QUESTIONS AND ANSWERS ABOUT THE MERGERS Q: WHAT IS PROPOSED? A: Allscripts and Channelhealth propose to combine their businesses and Allscripts will create a new holding company for itself and Channelhealth. Q: WHAT WILL HAPPEN IN THE MERGERS? A: In the mergers, Allscripts and Channelhealth will become separate wholly- owned subsidiaries of a new holding company, Allscripts Holding, Inc., which we refer to in the attached document as "New Allscripts." Channelhealth stockholders will become New Allscripts stockholders and will own approximately 22.6% of the New Allscripts common shares that will be outstanding after the mergers, or 22.0% on a fully diluted basis and treating option holders and warrant holders as stockholders, with the potential to receive additional shares if the Channelhealth business meets certain revenue goals through the end of the year 2002. Current Allscripts stockholders will own the remaining approximately 77.4%, or 78.0% on a fully diluted basis. Q: WHY ARE ALLSCRIPTS AND CHANNELHEALTH PROPOSING TO MERGE? A: Our companies are proposing to merge because we expect as a combined company to grow revenues and gross profit faster and beyond the levels that either company could achieve individually. We believe that the companies have complementary skills, and that the combined portfolio of product and service offerings will be more attractive to our respective current customers and potential future customers than either company's individual portfolio. In addition, we expect the combined company, through a ten-year strategic alliance agreement with IDX that will become effective upon completion of the merger transactions, to gain access to IDX's universe of doctors including approximately 118,000 physicians and over 2,000 client sites. Finally, we believe that the merger will create other cost savings opportunities through administrative and operational synergies. Please read the more detailed description of our reasons for the merger on pages 37 through 38. Q: WHAT WILL THE NEW COMPANY BE CALLED AND WHERE WILL IT BE HEADQUARTERED? A: The combined company will be called Allscripts Holding, Inc. and will be headquartered in Allscripts' current headquarters in Libertyville, Illinois. Q: WHAT WILL HAPPEN TO CHANNELHEALTH SHARES AND STOCK OPTIONS IN THE MERGERS? A: Channelhealth common and preferred stockholders will receive 0.33730 New Allscripts common shares for each share of Channelhealth common or preferred stock they own. Channelhealth stockholders also will receive cash for any fractional New Allscripts shares they would be otherwise entitled to receive. In addition, Channelhealth stock options will be converted into options to purchase New Allscripts common shares based on the same exchange ratio as applies to the conversion of Channelhealth stock, at an exercise price equal to the former exercise price under the Channelhealth option divided by the 0.33730 exchange ratio. The New Allscripts common shares will be authorized for quotation on the Nasdaq National Market under the ticker symbol "MDRX," which is Allscripts' current trading symbol. Q: WHAT WILL HAPPEN TO ALLSCRIPTS COMMON SHARES, STOCK OPTIONS AND WARRANTS IN THE MERGERS? A: Allscripts common stockholders and holders of Allscripts stock options or warrants will receive one New Allscripts common share, option or warrant for each share of Allscripts common stock they own or each option or warrant to purchase Allscripts common stock they hold. Allscripts warrants and stock options will be converted into warrants and options to purchase the same number of New Allscripts common shares, at the same exercise price and otherwise on the same terms, as currently apply. The New Allscripts 1

common shares will be authorized for quotation on the Nasdaq National Market under the trading symbol "MDRX," which is Allscripts' current trading symbol. Q: WHEN IS ALLSCRIPTS' SPECIAL STOCKHOLDERS' MEETING? A: Allscripts' special meeting of stockholders will take place on [ ], 2000. The location of the special meeting is specified on the cover page of this document. Q: HOW DO I VOTE MY ALLSCRIPTS SHARES IF MY SHARES ARE HELD IN "STREET NAME"? A: You should vote your shares in accordance with the instructions provided to you by your broker. Your broker will not vote your shares unless the broker receives appropriate instructions from you. Q: MAY I CHANGE MY VOTE EVEN AFTER RETURNING A PROXY CARD? A: Yes. If you are an Allscripts stockholder and want to change your vote, you may do so at any time before the Allscripts special meeting by sending to LaSalle Bank N.A., Allscripts' solicitation agent for the merger, at 135 South LaSalle Street, Chicago, Illinois 60603, a proxy with a later date. Alternatively, you may revoke your proxy by delivering to LaSalle Bank N.A., at 135 South LaSalle Street, Chicago, Illinois 60603, Room 1811, a written revocation prior to the Allscripts special meeting or by voting in person at the Allscripts special meeting. Allscripts stockholders that require assistance in changing or revoking a proxy should contact LaSalle Bank N.A. at (800) 246-5761. Q: IF I HAVE MORE QUESTIONS ABOUT THE MERGERS OR ALLSCRIPTS, WHERE CAN I FIND ANSWERS? A: In addition to reading this document, its annexes and the documents we have incorporated in this document by reference, you can find more information about the mergers or about Allscripts in its filings with the Securities and Exchange Commission and with the Nasdaq National Market. Q: WHAT WILL HAPPEN AT ALLSCRIPTS' SPECIAL STOCKHOLDERS' MEETING? A: At the Allscripts special meeting, Allscripts stockholders will vote on the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of New Allscripts common shares to Channelhealth stockholders in the merger with Channelhealth. We cannot complete the mergers unless, among other things, Allscripts stockholders vote to adopt and approve the merger agreement and the transactions contemplated by the merger agreement, including the issuance of New Allscripts shares to Channelhealth stockholders, and Channelhealth common and preferred stockholders, voting separately by class, vote to approve the merger agreement. Q: WHAT DO I NEED TO DO TO VOTE? A: Mail your signed proxy card in the enclosed return envelope as soon as possible so that your shares may be represented at the special meeting. In order to assure that we obtain your vote, please vote as instructed on your proxy card even if you currently plan to attend the special meeting in person. The members of the Allscripts board of directors unanimously recommend that Allscripts stockholders vote for the merger agreement and the transactions contemplated by the merger agreement, including the merger and issuance of New Allscripts shares to Channelhealth stockholders. Q: ARE THERE RISKS ASSOCIATED WITH THE MERGERS THAT I SHOULD CONSIDER IN DECIDING HOW TO VOTE? A: Yes. There are risks associated with all business combinations, including the mergers. In particular, you should be aware that the number of New Allscripts common shares that Channelhealth stockholders will receive is fixed and will not change as the market price of shares of Allscripts common stock fluctuates in the period before the mergers. Accordingly, the value of the New Allscripts common shares that 2

Channelhealth stockholders will receive in return for their shares of Channelhealth stock may be either less than or more than the current market price of the Allscripts common shares. There also are a number of other risks that are discussed in this document and in other documents incorporated by reference in this document. Please read with particular care the more detailed description of the risks associated with the mergers on pages 23 through 27. Q: WHEN DO YOU EXPECT TO COMPLETE THE MERGERS? A: We expect to complete the mergers as quickly as possible once all the conditions to the mergers, including obtaining the approvals of the Allscripts stockholders and the Channelhealth common and preferred stockholders at the special meetings, are fulfilled. Fulfilling some of these conditions is not entirely within our control. Q: SHOULD I SEND IN MY ALLSCRIPTS STOCK CERTIFICATES NOW? A: No. After the merger is completed, we will send written instructions to you that explain how to exchange your Allscripts stock certificates for New Allscripts stock certificates. New Allscripts will also send a letter of transmittal that you must execute. Please do not send in any stock certificates until you receive these written instructions and the letter of transmittal. 3

The Mergers (Page 35) Pursuant to the merger agreement, Bursar Acquisition, Inc. and Bursar Acquisition No. 2, Inc., each a separate subsidiary of New Allscripts, will merge with and into Allscripts and Channelhealth, respectively, and each of Allscripts and Channelhealth will survive the mergers as separate wholly-owned subsidiaries of New Allscripts. Allscripts Merger In the merger of Bursar with and into Allscripts, which we refer to as the Allscripts merger, each share of Allscripts common stock will be exchanged for one share of New Allscripts common stock. As of November 1, 2000, there were 29,351,770 shares outstanding (32,698,416 on a fully diluted basis and treating option and warrant holders as stockholders). Therefore, upon completion of the mergers, former Allscripts stockholders will own about 77.4% of the New Allscripts common stock (78.0% on a fully diluted basis) and former Channelhealth stockholders will own the remainder of the outstanding common stock. Channelhealth Merger In the merger of Bursar No. 2 with and into Channelhealth, which we refer to as the Channelhealth merger, each share of preferred stock and each share of common stock of Channelhealth will be exchanged for 0.33730 shares of common stock of New Allscripts. As of October 27, 2000 there were 25,527,425 shares of Channelhealth common stock and 2,719,429 shares of Channelhealth preferred stock, or 28,246,854 shares in the aggregate, outstanding (30,060,930 as of October 27, 2000 on a fully diluted basis and treating option holders as stockholders), but this total will be reduced by 2,771,009 shares of Channelhealth common stock pursuant to the Channelhealth/IDX asset purchase agreement described later in this document. Consequently, New Allscripts will issue 8,593,003 shares of its common stock to Channelhealth stockholders in exchange for the 25,475,845 shares of Channelhealth common and preferred stock that will be outstanding at the closing date for the mergers. Earnout Shares In addition, if, following completion of the mergers, Channelhealth meets specified revenue goals through the end of the year 2002, New Allscripts will issue up to an additional 1,599,374 shares of common stock to former Channelhealth stockholders on the basis of an exchange ratio of 0.06278 shares of New Allscripts common stock for each Channelhealth common or preferred share held at the effective time of the mergers.

NEW ALLSCRIPTS PRO FORMA CONSOLIDATED FINANCIAL INFORMATION Overview Effective May 9, 2000 and May 17, 2000, Allscripts, Inc. (the Company) acquired MasterChart, Inc. and Medifor, Inc., respectively (the Previously Acquired Companies). These acquisitions have been accounted for using the purchase method of accounting and, accordingly, the purchase price has been allocated to the tangible and identifiable intangible assets acquired and liabilities assumed on the basis of their respective fair values on the acquisition dates, with the excess of the purchase price recorded as goodwill. As soon as practicable after the filing of this joint proxy statement/prospectus, the Company expects to acquire the Physician Channel business of Channelhealth Incorporated. This acquisition will be accounted for using the purchase method of accounting and, accordingly, the purchase price will be allocated to the tangible and identifiable intangible assets acquired and liabilities assumed on the basis of their respective fair values on the acquisition date, with the excess of the purchase price recorded as goodwill. The MasterChart, Inc. total purchase price of approximately $132.7 million consisted of 1,617,873 shares of the Company's common stock with a fair value of approximately $127.4 million, cash of approximately $5 million and transaction costs totalling approximately $.3 million. The Medifor, Inc. total purchase price of approximately $38.8 million consisted of 935,858 shares of the Company's common stock with a fair value of approximately $34.4 million and the issuance of 142,786 common stock options as replacement of Medifor, Inc. common stock options with a fair value of approximately $4.2 million and transaction costs totalling approximately $.2 million.

Additional consideration may be granted relative to the Physician Channel acquisition if certain revenue targets are achieved during 2002. Those revenue targets, if achieved, will result in the recording of additional purchase price at the time that the targets are met. Allscripts has not yet performed a final valuation of the tangible and identifiable intangible assets and liabilities to be acquired relative to the Physician Channel acquisition. As such, the pro forma adjustments related to the Physician Channel are preliminary estimates that are subject to change. The following unaudited pro forma consolidated statements of operations reflects the Company's results of operations for the year ended December 31, 1999, and six months ended June 30, 2000, as if the acquisitions had occurred on January 1, 1999, after giving effect to purchase accounting adjustments. The following unaudited pro forma consolidated balance sheet reflects the Company's financial position as of June 30, 2000, as if the Physician Channel acquisition had occurred on June 30, 2000, after giving effect to purchase accounting adjustments.

Net Loss per Share Basic net loss per share for the year ended December 31, 1999 and the six months ended June 30, 2000 is computed using the weighted average number of common shares outstanding during the respective period. Diluted net loss per share is computed excluding the weighted average number of common equivalent shares outstanding because such common equivalents are anti-dilutive. Differences between historical weighted average shares outstanding used to compute net loss per share result from the inclusion of shares issued in conjunction with the acquisitions as if such shares were outstanding from January 1, 1999. 19

CAUTIONARY STATEMENT ABOUT FORWARD-LOOKING STATEMENTS This proxy statement/prospectus and the documents incorporated by reference in this proxy statement/prospectus contain forward-looking statements with respect to the mergers and the financial condition, results of operations, plans, objectives, future performance and business of Allscripts, New Allscripts and Channelhealth. These statements appear in a number of places and include statements regarding our plans, beliefs or current expectations including those plans, beliefs and expectations of our officers and directors with respect to, among other things, future operating results, the ability to generate revenue, profitability or cost savings following completion of the mergers. These forward-looking statements involve certain risks and uncertainties. When considering such forward-looking statements, you should keep in mind the risk factors and other cautionary statements in this proxy statement/prospectus and the documents incorporated by reference in this proxy statement/prospectus. You should understand that various factors, in addition to those discussed elsewhere in this proxy statement/prospectus and in the documents referred to or incorporated by reference in this proxy statement/prospectus, could affect the future results of the combined company following the mergers and could cause results to differ materially from those expressed in these forward- looking statements, including: . changes in general economic conditions or in political, regulatory or competitive forces; . changes in the securities markets; . dependence on key personnel to manage the integration of the two companies; . risk that our analyses of these risks and forces could be incorrect or that the strategies developed to address them could be unsuccessful; . risks described below under "Risk Factors;" and . description of future tax consequences. Stockholders are cautioned not to place undue reliance on these forward- looking statements, which speak only as of the date of this proxy statement/prospectus or, in the case of documents incorporated by reference in this proxy statement/prospectus, the dates of those documents. All subsequent written and oral forward-looking statements attributable to Allscripts, New Allscripts or Channelhealth or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. None of Allscripts, New Allscripts or Channelhealth undertakes any obligations to release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date of this proxy statement/prospectus or to reflect the occurrence of unanticipated events. 22

RISK FACTORS In addition to the other information contained in this proxy statement/prospectus and the documents incorporated by reference in this proxy statement/prospectus, you should carefully consider the following risk factors before you decide how to vote on the proposed transaction. The value of the New Allscripts shares to be received in the mergers will fluctuate. Pursuant to the terms of the merger agreement, at the effective time of the mergers, each outstanding share of Channelhealth common stock and each outstanding share of Channelhealth preferred stock, other than shares held in the treasury of Channelhealth and shares held by persons who have perfected appraisal rights, will be converted into the right to receive 0.33730 shares of New Allscripts common stock, plus cash in lieu of fractional share interests, and each outstanding share of Allscripts common stock, other than shares held in the treasury of Allscripts, will be converted into one share of New Allscripts common stock. The merger agreement does not provide for any adjustment of the number of shares of New Allscripts common stock issuable for each share of Channelhealth common or preferred stock or Allscripts common stock based upon fluctuations in the price of Allscripts common stock. Accordingly, the value of the stock consideration to be received by holders of Channelhealth common or preferred stock upon the consummation of the transaction, and the corresponding dilution, if any, to holders of Allscripts common stock, are not presently ascertainable and will depend upon the market price of New Allscripts common stock at the effective time of the mergers, which in turn will be affected by the market price of Allscripts common stock at that time. On July 12, 2000, the last trading day prior to the public announcement of the execution of the merger agreement, the closing price of Allscripts common stock on the Nasdaq National Market was $29.125 per share. On [ ], 2000 (the latest practicable date prior to the printing of this proxy statement/prospectus), the closing price of Allscripts common stock on the Nasdaq National Market was $[ ] per share. Holders of Allscripts common stock and holders of Channelhealth stock are urged to obtain current market quotations for Allscripts common stock prior to making any decisions with respect to the merger proposals. The merger agreement does not provide Allscripts, Channelhealth or IDX the right to terminate the agreement based upon fluctuation in the price of Allscripts common stock. Such variations may be the result of: . actual or anticipated variations in Allscripts' quarterly operating results; . announcements of technological innovations or new services or products by Allscripts or its competitors; . timeliness of Allscripts' introductions of new products; . changes in financial estimates by securities analysts; . conditions and trends in the electronic healthcare information, Internet, e-commerce and pharmaceutical markets; and . general market conditions and other factors. In addition, the stock markets, especially the Nasdaq National Market, have recently experienced extreme price and volume fluctuations that have affected the market prices of equity securities of many technology companies, and Internet-related companies in particular. These fluctuations have often been unrelated or disproportionate to operating performance. These broad market factors may materially affect the trading price of Allscripts' common stock. General economic, political and market conditions like recessions and interest rate fluctuations may also have an adverse effect on the market price of Allscripts' common stock. Volatility in the market price for Allscripts' common stock may result in the filing of securities class action litigation. On October 26, 2000, Allscripts announced that its previously reported revenues for the second quarter of 2000 were being revised from $12.6 million to $12.1 million. Two complaints, styled as shareholder class action complaints, have been filed in the United States District Court for the Northern District of Illinois against Allscripts and its President and Chief Financial Officer, David B. Mullen, alleging that the defendants failed to disclose that revenue relating to Allscripts' relationship with IMS Health was not properly recorded in the second quarter of 2000. The complaints in these actions purport to be brought on behalf of 23

individuals who purchased common stock of Allscripts during the period of July 27, 2000 through and including October 26, 2000. The plaintiffs allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and seek unspecified damages. According to reports on the Internet, at least one additional similar complaint has been filed against Allscripts. At this time, management is unable to determine the likely outcome of this matter or to reasonably estimate the amount of loss with respect to this matter. In addition, these actions could result in substantial costs and the diversion of management's attention and resources. New Allscripts may face difficulties in integrating the operations and products of Channelhealth and Allscripts. Channelhealth and Allscripts have previously operated separately. The proposed management team of New Allscripts does not have experience with the combined business. Integration of product lines will involve consolidation of products with duplicative functionality, coordination of research and development activities and convergence of the technologies supporting the various products. New Allscripts may not be able to integrate the products, product development, information systems and operations of Channelhealth and Allscripts without a loss of key officers, employees, customers or suppliers, a loss of revenues or an increase in net loss, an increase in operating or other costs or other difficulties. In addition, New Allscripts may not be able to realize the operating efficiencies, the material expansion of its customer base to IDX customers or the other benefits expected from the Channelhealth merger and related transactions such as the strategic alliance with IDX. Any unexpected costs or delays incurred in connection with such integration could have an adverse effect on New Allscripts' business, results of operations or financial condition. Allscripts is currently experiencing losses and New Allscripts may not become profitable in the future. Allscripts is currently experiencing losses and cannot assure you that New Allscripts will become profitable in the foreseeable future, if ever. For the six months ended June 30, 2000 and the year ended December 31, 1999, Allscripts had losses of $26.9 million and $11.2 million, respectively. Even if New Allscripts does achieve profitability it may be unable to sustain or increase its profitability in the future. The business separation of Channelhealth from IDX may impair assets. The separation of Channelhealth from the rest of IDX's businesses, assets and liabilities pursuant to the asset purchase agreement between IDX and Channelhealth requires the transfer of assets, including intellectual property rights, between Channelhealth and IDX. Some of these transfers may trigger Channelhealth liabilities that will not become payable by Channelhealth until after the mergers are completed. Generally, IDX will be responsible for these liabilities but IDX would not be required to indemnify Channelhealth for any losses that are consequential, in the nature of lost profits, diminution in value, damage to reputation or the like, special or punitive damages or otherwise not actual losses. Channelhealth expects to continue to incur losses and may never achieve profitability, which may cause New Allscripts' stock price to fall. Historically, Channelhealth has incurred significant net losses, and since Channelhealth has only recently implemented its business strategy, Allscripts and Channelhealth expect Channelhealth to continue to incur losses at least through 2001. Additionally, Channelhealth has spent significant amounts on research and development and sales and marketing efforts, and Channelhealth expects these costs to continue. Channelhealth and Allscripts cannot be certain that Channelhealth will achieve profitability and if it is unable to do so, New Allscripts' business prospects may be harmed and New Allscripts' stock price may fall. Channelhealth recently began independent operations and its limited operating history makes an evaluation of its business and prospects difficult. Since its inception as an independent company in September 1999, Channelhealth's operating activities have consisted largely of developing the applications necessary to provide its services and Channelhealth has only recently begun to sell its services to provider organizations. In addition, Channelhealth's long-term success 24

will depend largely on the success of its strategic relationships and the strategic alliance between New Allscripts and IDX. Channelhealth is still in the early stages of its current strategic relationships and it is unable to predict whether the goals of those relationships will be achieved. Channelhealth's limited operating history and limited experience with its strategic business partners make it difficult to evaluate its business following the Channelhealth merger and prospects. Channelhealth's historical financial information may not be representative of its results as a company separate from IDX. Channelhealth's financial statements, which reflect the operations and net assets of the "Physician Channel" business of Channelhealth and exclude the operations and net assets of the "Patient Channel" business and the "eCommerce Channel" business to be retained by IDX, have been derived from the consolidated financial statements of IDX using the historical results of operations and historical bases of the assets and liabilities of IDX. Accordingly, the historical financial information included in this proxy statement/prospectus does not necessarily reflect what Channelhealth's financial position, results of operations and cash flows would have been as a separate, stand-alone entity during the periods presented. In addition, such information may not necessarily be indicative of what Channelhealth's financial position, results of operations and cash flows will be in the future as a wholly-owned subsidiary of New Allscripts. Its historical costs and expenses include allocations from IDX for centralized administrative services and infrastructure costs, including accounting, cash management, information management, property management, human resources, legal services and purchasing of materials, equipment and supplies. Channelhealth and IDX have determined these allocations on bases that they consider to be reasonable reflections of Channelhealth's utilization of services provided or the benefit Channelhealth received from such services. Channelhealth has not made adjustments to its historical financial information to reflect many significant changes that will occur in its cost structure, funding and operations as a result of its separation from IDX. Channelhealth's and New Allscripts' growth and revenues could suffer if they are unable to enter into and maintain relationships with IDX customers. Channelhealth seeks to increase its subscriber base through targeting provider organizations that use IDX practice management systems or other IDX services, and affiliates of these organizations. Channelhealth's services use the Web FrameWork technology, which it licenses from IDX, and which enables its software applications and services to be tightly integrated with IDX practice management systems and provide real-time synchronization of data. If Channelhealth's relationship with IDX terminates, its services might not be as attractive to IDX customers and Channelhealth may not have access to this potential customer base, IDX might enter into arrangements that would allow Channelhealth's competitors to utilize IDX technology and IDX could compete against Channelhealth. If any of these situations were to occur, Channelhealth's and New Allscripts' expected revenues may be lower, their business may be harmed and New Allscripts' stock price may fall. Channelhealth's and New Allscripts' business will be harmed if they cannot maintain Channelhealth's strategic alliance agreement with Healtheon/WebMD. On June 8, 2000, Channelhealth and IDX entered into agreements with Healtheon/WebMD Corp. pursuant to which Healtheon/WebMD agreed to provide electronic transaction and content services to Channelhealth and IDX. Pursuant to the agreement, Healtheon/WebMD's content is to be integrated into Channelhealth's Physician Channel and Patient Channel internet services. Healtheon/WebMD further committed to a multi-million dollar campaign promoting IDX and Channelhealth products and services that incorporate Healtheon/WebMD content and transactions. Healtheon/WebMD has recently informed IDX that it believes Channelhealth and IDX will be unable to perform their obligations to Healtheon/WebMD if the proposed strategic alliance between Allscripts and IDX is consummated. Healtheon/WebMD also stated that it would seek to terminate the Channelhealth 25

agreement and would propose a "restructured" relationship with IDX. Such proposal has not been received by IDX. Allscripts and Channelhealth believe that Channelhealth's and IDX's performance will not be impaired by the strategic alliance with Allscripts and that Healtheon/WebMD does not have a basis for unilaterally terminating the Channelhealth or restructuring the IDX agreement. In addition, pursuant to the strategic alliance agreement between Allscripts and IDX, each of Allscripts and IDX agree not to take any action which would cause a default under or termination of the agreement between Channelhealth and Healtheon/WebMD. In the event the Healtheon/WebMD agreement is terminated, Channelhealth's and New Allscripts' expected revenues for 2001 may be significantly lower than currently anticipated, their business' may be harmed and New Allscripts' stock price may fall. Channelhealth's and New Allscripts' business will be harmed if they cannot maintain the strategic alliance agreement and the cross license agreement with IDX. Upon completion of the mergers, New Allscripts will enter into a 10-year strategic alliance agreement with IDX pursuant to which New Allscripts and IDX will agree to coordinate product development and align their respective marketing processes. Under this agreement IDX will grant New Allscripts the exclusive right to market, sell, license and distribute ambulatory point-of- care and clinical application products to IDX customers. This agreement does not, however, limit IDX's continued development and distribution of its own "LastWord" or radiology products and services. Channelhealth's and New Allscripts' business strategy includes targeting current and prospective IDX customers and their affiliates. If Channelhealth and New Allscripts fail to successfully implement that business strategy, Channelhealth and New Allscripts may not be able to achieve projected results or support the price paid for Channelhealth. If IDX does not renew the strategic alliance agreement, or if such agreement is terminated, Channelhealth and New Allscripts would lose access to an important customer base. After the expiration or termination of the strategic alliance agreement, New Allscripts may not be able to align with another company to market and distribute its products on as favorable a basis as that represented by the IDX strategic alliance. This would harm New Allscripts' growth and revenue. In addition, prior to the termination of this agreement, New Allscripts cannot allow certain specified IDX direct competitors to market, distribute or sell its or Channelhealth's services, even if such an agreement would benefit New Allscripts' business. Also upon completion of the mergers, Channelhealth will enter into an amended and restated cross license and software maintenance agreement with IDX pursuant to which Channelhealth grants IDX a license to use, market and sublicense its products combined with IDX products, and IDX grants Channelhealth a license to use, market and sublicense IDX software for use with Channelhealth products. If this agreement is terminated, Channelhealth will not have access to IDX software, which would harm its and New Allscripts' ability to integrate their services with IDX systems and provide real-time data synchronization. This would make Channelhealth's systems less desirable to IDX customers and would harm its business. New Allscripts may have substantial sales of its common stock after the transaction closes that could cause its stock price to fall. Allscripts' common stock began trading on the Nasdaq National Market on July 23, 1999. After the mergers are completed, a substantial number of New Allscripts shares will be eligible for public sale at various times thereafter. Sales of a substantial number of shares of New Allscripts common stock after the transaction closes could cause New Allscripts' stock price to fall. Because New Allscripts' executive officers and directors will have substantial control of its voting stock, takeovers not supported by them will be more difficult, possibly preventing New Allscripts stockholders from obtaining an optimal share price. Upon completion of the merger, New Allscripts executive officers and directors will beneficially own or control [ ] shares or [ ]% of the outstanding New Allscripts common stock. If the New Allscripts executive officers and directors choose to act or vote together, they will have the power to influence 26

significantly all matters requiring the approval of New Allscripts stockholders, including the election of directors and the approval of significant corporate transactions. Without the consent of these stockholders, New Allscripts could be prevented from entering into transactions that could be beneficial to it or its stockholders as a whole. Pursuant to the stock rights and restrictions agreement by and between IDX and New Allscripts, IDX will be subject to various limitations and restrictions surrounding its ownership of voting securities of New Allscripts. In limited circumstances, under the stock rights and restrictions agreement, IDX must vote all of its shares of New Allscripts securities in accordance with the recommendation of the New Allscripts board of directors. This voting limitation permits New Allscripts' directors to have substantial control over New Allscripts' voting stock. Certain stockholders, directors and/or officers may have interests that are diverse or in addition to the remaining stockholders of Channelhealth. In considering the recommendation of the Channelhealth board of directors with respect to the Channelhealth merger, stockholders of Channelhealth should be aware that certain members of Channelhealth's management, certain stockholders and the Channelhealth board of directors have certain interests in the merger that may present them with actual or potential conflicts of interests. Completion of the merger will result in the appointment of Richard E. Tarrant, Channelhealth's current Chairman of the Board, Chief Executive Officer and President, to the New Allscripts board of directors to serve initially as New Allscripts' sole non-executive Vice Chairman. Additionally, New Allscripts will enter into an employment agreement with Pamela Pure, currently Channelhealth's Vice President and Chief Operating Officer, with a term of three years and a renewal option. New Allscripts will also enter into severance agreements with certain specified Channelhealth management employees, which will provide upon termination of the employee's employment with New Allscripts prior to the first anniversary date following the completion of the merger transactions for any reason other than cause, that the employee will receive a cash severance payment equal to one-half of his or her annual salary. Pursuant to the merger agreement, New Allscripts will assume all outstanding Channelhealth employee stock options, excluding those stock options granted under IDX's stock option plans, and convert each of those options into an option to purchase New Allscripts common stock. New Allscripts and Allscripts also agreed to guarantee, and to cause Channelhealth to maintain and perform, Channelhealth's existing indemnification obligations to present and former directors and officers of Channelhealth, with respect to matters occurring through completion of the mergers to the extent required under Channelhealth's certificate of incorporation and by-laws. In addition, pursuant to the Channelhealth/IDX asset purchase agreement, IDX, the majority stockholder of Channelhealth, will acquire the eCommerce Channel and certain components of the Patient Channel in exchange for shares of Channelhealth common stock held by IDX. Channelhealth did not obtain a fairness opinion in connection with the transactions contemplated by the merger agreement. Stockholders of Channelhealth should be aware that Channelhealth did not retain a financial advisor to assist it in its negotiations with Allscripts (including, without limitation, rendering a fairness opinion) and its consideration of other alternative transactions available to Channelhealth. In reaching its conclusion not to retain a financial advisor, the Channelhealth board of directors considered the expertise and experience of the non-employee members of Channelhealth's board of directors. As a result, the Channelhealth board of directors was confident that it possessed the sophistication and expertise to evaluate the fairness of the merger and to recommend it to Channelhealth's stockholders consistent with its fiduciary duties without incurring the expense of retaining a financial advisor. 27

THE TRANSACTION Overview The merger agreement provides for a business combination between Allscripts and Channelhealth and the creation of a new holding company, which we refer to in this document as "New Allscripts," for Allscripts and Channelhealth. To implement these transactions, prior to signing the merger agreement Allscripts formed New Allscripts as a wholly-owned subsidiary of Allscripts and formed Bursar Acquisition, Inc. and Bursar Acquisition No. 2, Inc. as wholly-owned subsidiaries of New Allscripts. The merger agreement provides for the merger of Bursar with and into Allscripts and the merger of Bursar No. 2 with and into Channelhealth, in each case in exchange for shares of New Allscripts' common stock, with Allscripts and Channelhealth surviving the mergers as wholly-owned subsidiaries of New Allscripts. In the mergers, each outstanding share of Allscripts common stock will be converted into one share of New Allscripts common stock and each outstanding share of Channelhealth common stock and Channelhealth preferred stock will be converted into the right to receive 0.33730 shares of New Allscripts common stock. As a result of the mergers, the former holders of Allscripts common stock collectively will hold approximately 77.4% (approximately 78.0% on a fully diluted basis and treating option and warrant holders as former stockholders) of the issued and outstanding shares of New Allscripts common stock and the former holders of Channelhealth common and preferred stock collectively will hold approximately 22.6% (approximately 22.0% on a fully diluted basis and treating option and warrant holders as former stockholders) of the issued and outstanding shares of New Allscripts common stock. In addition, if following the completion of the mergers the Channelhealth business generates specified minimum sales revenue during 2002, New Allscripts will issue additional shares to former Channelhealth stockholders with the result that their fully diluted percentage ownership interest in New Allscripts would increase to as much as 24.3%, based on the number of fully diluted New Allscripts shares calculated at the effective time of the merger. Prior to the closing of the mergers, pursuant to an asset purchase agreement executed at the same time as the merger agreement, IDX will acquire Channelhealth's "eCommerce Channel" and "Patient Channel" businesses and associated assets, rights, obligations and liabilities in consideration of the return to Channelhealth of 2,771,009 shares of Channelhealth common stock currently owned by IDX. In addition, upon completion of the mergers, New Allscripts and IDX will execute a stock rights and restrictions agreement, a 10-year strategic alliance agreement and a cross license agreement. The material terms of these agreements are summarized in "The Related Transaction Agreements." Background In early 1999, IDX established a division to conduct its Internet business under the brand name "IDX.com." On October 1, 1999, IDX reorganized its Internet business by combining IDX.com and Channelhealth, Inc., an independent privately held company acquired by IDX in April 1999. In January 2000, Channelhealth completed the placement of 2,719,429 shares of its Series A Convertible Preferred Stock to Pequot Private Equity Fund II, L.P., as lead investor, and others. In the first quarter of 2000, Channelhealth considered an initial public offering, but aborted the plan following the general decline in the stock market price of equity securities of technology and Internet-related companies that commenced late in the first quarter of 2000. As part of its strategy of expanding its product and service offerings and growing its business by reaching new customers, Allscripts regularly evaluates acquisition opportunities involving businesses that it believes are complementary. In April 2000, representatives of Allscripts and IDX met to discuss the possible merger of Allscripts and Channelhealth. On April 26, 2000, Allscripts and IDX executed a non-disclosure agreement and commenced furnishing non-public information regarding Allscripts and Channelhealth, respectively. In May 2000, Allscripts engaged Goldman Sachs as its exclusive financial advisor in connection with the Channelhealth opportunity. An 35

Allscripts team conducted preliminary due diligence on Channelhealth at IDX's facilities in Burlington, Vermont in early May 2000. Members of Channelhealth's management team, including Vincent Estrada and Pamela Pure, as well as IDX's General Counsel, Robert W. Baker, Jr., and Chief Financial Officer, Jack Kane participated in the diligence meetings and IDX's Chief Executive Officer, Richard E. Tarrant, attended via teleconference. Allscripts completed its preliminary valuation analyses and preliminary due diligence on Channelhealth on May 9, 2000. Between May 9, 2000 and June 16, 2000, representatives of Allscripts, Channelhealth and IDX held several discussions about various transaction structures. Based on those discussions, Allscripts and IDX concluded that Allscripts' acquisition of Channelhealth, without the "eCommerce" and "Patient Channel" businesses, was the transaction structure most likely to meet the strategic goals of both parties. On June 16, 2000, Allscripts delivered an offer to IDX to acquire Channelhealth, without its "eCommerce Channel" and "Patient Channel" businesses, in consideration of a 21.3% equity ownership in Allscripts for former Channelhealth stockholders on a fully diluted basis, with additional shares to be issued to increase the former Channelhealth stockholders' aggregate fully diluted ownership percentage to as much as 24.3% if the Channelhealth business generated specified minimum post-closing sales revenue. IDX's management preliminarily approved the Allscripts proposal, subject to approval of the parties' boards of directors, the negotiation and execution of definitive agreements and the completion of further confirmatory due diligence. On July 2, 2000, Allscripts' counsel provided an initial draft of a share exchange agreement and the stock rights and restrictions agreement to IDX, Channelhealth and their respective counsel. Over the Fourth of July holiday weekend, representatives of the parties conducted negotiations by telephone and e-mail, and concluded that the transaction should go forward using the holding company structure reflected in the merger agreement. Allscripts' counsel circulated a draft merger agreement reflecting the holding company structure on July 3, 2000. On July 5, 2000, Mr. Baker of IDX provided an initial draft of the strategic alliance agreement to Allscripts and its counsel. Thereafter, negotiations continued among representatives of Allscripts, Channelhealth and IDX on the merger agreement, the stock rights and restrictions agreement, the strategic alliance agreement and the other transaction agreements, and among representatives of IDX and Channelhealth on an asset purchase agreement pursuant to which the assets, rights, obligations and liabilities associated with Channelhealth's "eCommerce Channel" and "Patient Channel" businesses would be transferred to IDX prior to completion of the mergers in consideration of the return by IDX to Channelhealth of a number of shares of Channelhealth's common stock owned by IDX. On July 6, 2000, the Allscripts board of directors was updated by Allscripts management as to the status of the merger negotiations. The Allscripts board of directors met by telephone conference call during the morning of July 12, 2000 to receive an update on negotiations with respect to the merger agreement and related transaction agreements. The board received a report from Glen E. Tullman, Chairman of the Board and Chief Executive Officer of Allscripts, representatives of Goldman Sachs and representatives of Weil, Gotshal & Manges LLP, outside counsel to Allscripts. The board reconvened by telephone conference call late in the evening of July 12, again with the participation of representatives of Goldman Sachs and Weil Gotshal. At this meeting, the board reviewed with management, their financial advisors and counsel the terms of the merger agreement and the other significant transaction agreements. Goldman Sachs made a presentation as to the fairness from a financial point of view, of the merger consideration to be paid to the holders of Channelhealth common stock by Allscripts pursuant to the merger agreement. Following discussion and a question and answer period with representatives of Goldman Sachs and Weil Gotshal, the Allscripts board unanimously approved the merger agreement and the merger contemplated by the merger agreement, approved the related transaction agreements and authorized management to proceed with execution and delivery of the merger agreement, subject to confirmation that Goldman Sachs would be prepared to issue its written fairness opinion based upon the final language of the merger agreement and related transaction agreements as negotiated by management and counsel with their counterparts at IDX, Channelhealth and their respective counsels. On July 11, 2000, the Channelhealth board of directors appointed a special committee comprised of the two directors not employed by IDX or Channelhealth. On July 12, the special committee reviewed with 36

management and legal counsel the transaction agreements and voted to recommend approval of the merger agreement and the transactions contemplated by the merger agreement, including the transfer of assets to IDX pursuant to the Channelhealth/IDX asset purchase agreement and determined that the transactions were in the best interests of the stockholders of Channelhealth. Later that day, the Channelhealth board of directors unanimously approved the merger agreement and the transactions contemplated by it and the Channelhealth/IDX asset purchase agreement. On July 13, 2000, prior to the commencement of trading on the Nasdaq National Market, the parties executed the merger agreement and announced the transaction. Recommendation of the Allscripts Board of Directors; Allscripts' Reasons for the Transaction At its second meeting on July 12, 2000, the Allscripts board of directors unanimously approved the merger agreement and the transactions contemplated by the merger agreement, including the issuance to the stockholders of Channelhealth of the number of shares of New Allscripts common stock necessary to complete the merger with Channelhealth, and determined that the transactions were in the best interests of the stockholders of Allscripts. THE ALLSCRIPTS BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT HOLDERS OF ALLSCRIPTS COMMON STOCK VOTE FOR THE MERGER PROPOSAL. In reaching its determination to approve the merger agreement and the transactions contemplated by the merger agreement, the Allscripts board considered a number of factors, including, without limitation, the factors listed below. . New Allscripts, through the strategic alliance agreement, will gain access to IDX's universe of doctors including approximately 118,000 physicians and over 2,000 client sites comprised of over 265 large-group practices (greater than 75 physicians), over 510 small group practices (fewer than 75 physicians) and over 280 integrated delivery networks representing more than 370 hospitals. . The transaction adds potentially high-growth businesses, which are expected to increase 2001-2003 annual revenues. . The potential exists for revenue synergies if New Allscripts can achieve its goal of significantly penetrating the installed base of existing IDX customers with sales of Allscripts' current products and the potential exists for cost savings if New Allscripts can achieve its goal of reducing materially Channelhealth's overhead expenses. . The transaction is not expected to postpone Allscripts' projected profitability in the first quarter of 2002 (on a cash earnings per share basis), while adding potentially high-growth businesses. . The Allscripts merger is expected to be completed on a tax-deferred basis for federal income tax purposes. . The transaction is expected to accelerate Channelhealth's ability to increase physician adoption of its "Physician Channel" services through the contribution by Allscripts of direct sales representatives as well as service and support technicians, and the contribution by IDX of sales representatives committed to meeting sales quotas for Channelhealth offerings and combined Allscripts/Channelhealth product offerings. . The transaction represents a cost-effective way for Allscripts to broaden the functionality of its TouchScript product by (1) providing methodology for reporting medically significant results such as transcriptions and lab results, (2) strengthening its point-of-care offerings through inclusion of lab ordering, referrals, charge capture and other clinical transactions and (3) integrating its TouchScript point-of-care applications with Channelhealth's Physician Homebase product. . The presentation to the Allscripts board of directors by representatives of Goldman Sachs and the opinion of Goldman Sachs delivered to the Allscripts board of directors to the effect that the merger 37

consideration to be paid to the holders of Channelhealth common stock by Allscripts pursuant to the merger agreement was fair to Allscripts from a financial point of view. See "--Opinion of Allscripts' Financial Advisor." In view of the number and wide variety of factors considered in connection with its evaluation of the transaction, the Allscripts board did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors considered in reaching its determination. In addition, the Allscripts board did not undertake to make any specific determination as to whether any particular factor (or any aspect of any particular factor) was favorable or unfavorable to its ultimate determination; rather, it reached a general consensus that the transaction was in the best interest of Allscripts and its stockholders. In considering the factors described above, individual members of the Allscripts board may have given different weight to different factors. The Allscripts board members realize that there are risks associated with the transaction, including that some of the potential benefits set forth above may not be realized or that there may be significant costs associated with realizing such benefits. The Allscripts board also considered factors such as the risks associated with (1) New Allscripts' ability to retain Channelhealth's management, key employees and sales personnel, (2) New Allscripts' ability to maintain and expand relationships with IDX's customers, (3) New Allscripts' and Channelhealth's ability to maintain licensing, marketing and distribution arrangements with IDX following completion of the mergers and (4) the limited operating history and historical losses of Channelhealth. These factors are discussed more fully in this proxy statement/prospectus on page 23 under "Risk Factors." Recommendation of the Special Committee and the Board of Directors of Channelhealth; Channelhealth's Reasons for the Transaction On July 11, 2000, the Channelhealth board of directors appointed a special committee comprised of the two directors not employed by IDX or Channelhealth. On July 12, the special committee voted to recommend approval of the merger agreement and the transactions contemplated by the merger agreement and the transfer of assets to IDX pursuant to the Channelhealth/IDX asset purchase agreement and determined that the transactions were fair and in the best interests of the stockholders of Channelhealth. Later that day, the Channelhealth board of directors unanimously approved the merger agreement and the transactions contemplated by it and the Channelhealth/IDX asset purchase agreement. THE CHANNELHEALTH BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT HOLDERS OF CHANNELHEALTH VOTING STOCK VOTE FOR THE MERGER PROPOSAL. The special committee, in resolving to recommend approval of the merger agreement and the transactions contemplated by the merger agreement, and the Channelhealth board of directors, in reaching its determination to approve the merger agreement and the transactions contemplated by the merger agreement, considered a number of factors, including, without limitation, the factors listed below: . The potential exists for revenue synergies if New Allscripts can achieve its goal of accelerating significantly Channelhealth's product rollout and market penetration and the potential exists for cost savings if New Allscripts can achieve its goal of reducing materially Channelhealth's overhead expenses. . The mergers are expected to be completed on a tax-deferred basis for federal income tax purposes (other than with respect to cash received in lieu of fractional shares). . The transaction is anticipated to accelerate Channelhealth's ability to increase physician adoption of its "Physician Channel" services through the contribution by Allscripts of direct sales representatives as well as service and support technicians, and the contribution by IDX of sales representatives committed to meeting sales quotas for Channelhealth offerings and combined Allscripts/Channelhealth product offerings. 38

. The transaction represents a cost-effective way for Channelhealth to broaden the functionality of its "Physician Channel" services by (1) providing linkage to transcription services which, combined with Allscripts' MasterChart technology, provides a highly competitive offering and (2) integrating with Allscripts' TouchScript point-of-care applications. . The transaction is anticipated to enable Channelhealth to more effectively distribute its product offerings through Allscripts' sales distribution channels. . The structure of the merger that affords Channelhealth stockholders a choice of whether to seek complete or increased liquidity after the merger through a sale of New Allscripts common stock on the open market or to continue their investment in Channelhealth, through New Allscripts. . By receiving New Allscripts common stock, the Channelhealth stockholders will have an investment in a larger company, which the Channelhealth board of directors believes offers greater financial resources and flexibility, competitive strength and business opportunities than would be possible for Channelhealth alone. Thus, the Channelhealth board of directors has concluded that the merger provides Channelhealth stockholders with better long-term prospects and liquidity than if they continued to hold their Channelhealth common shares and preferred shares. . During the period of March 2000 through April 2000, the Channelhealth board of directors considered an initial public offering of equity securities of Channelhealth. Considering the various factors necessary to complete a successful initial public offering and given the current market climate, the Channelhealth board of directors concluded that Channelhealth could not reasonably anticipate completing such a transaction in the near future. Furthermore, there could be no assurances that the market would be amenable to a public offering by Channelhealth at the time or that a favorable price could be achieved. . The Channelhealth board of directors reviewed with its counsel and with management the provisions of the merger agreement and determined that its terms permitted Channelhealth to achieve the tax-deferred disposition of its business for marketable securities in a manner that is fair to the Channelhealth stockholders. Based upon the foregoing, the Channelhealth board of directors concluded at its July 12, 2000 meeting that the merger represents the best strategic alternative currently available to maximize the return to Channelhealth stockholders. In view of the wide variety of factors considered in connection with the evaluation of the merger, the Channelhealth board of directors did not find it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it considered in reaching its determination. Opinion of Allscripts' Financial Advisor On July 13, 2000, Goldman Sachs delivered its oral opinion, which it confirmed in a written opinion dated as of July 13, 2000, to the Allscripts board of directors, that as of the date of such opinion the merger consideration to be paid to the holders of Channelhealth common stock by Allscripts pursuant to the merger agreement was fair from a financial point of view to Allscripts. The full text of the written opinion of Goldman Sachs dated July 13, 2000, which sets forth assumptions made, matters considered and limitations on the review undertaken in connection with the opinion, is contained in Annex B. Goldman Sachs provided its advisory services and its opinion for the information and assistance of the Allscripts board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Allscripts common stock should vote at the Allscripts special meeting. Stockholders of Allscripts are urged to read such opinion in its entirety. In connection with its opinion, Goldman Sachs reviewed, among other things: . the merger agreement; 39

. the form of strategic alliance agreement; . the form of stock rights and restrictions agreement; . the annual report to stockholders and annual report on Form 10-K of Allscripts for the year ended December 31, 1999; . the annual reports to stockholders and annual reports on Form 10-K of IDX for the five years ended December 31, 1999; . a number of interim reports to stockholders and quarterly reports on Form 10-Q of Allscripts and IDX; . certain other communications from Allscripts and IDX to their respective stockholders; and . a number of internal financial analyses and forecasts for Allscripts and Channelhealth prepared by their respective managements, including certain cost savings and operating synergies projected by the management of Allscripts to result from the transactions contemplated by the merger agreement. Goldman Sachs also held discussions with members of the senior management of Allscripts regarding the strategic rationale for, and the potential benefits of, the transactions contemplated by the merger agreement and its past and current business operations, financial condition and future prospects. In addition, Goldman Sachs reviewed the reported price and trading activity for the Allscripts common stock, compared financial and stock market information for Allscripts and financial information for Channelhealth with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the healthcare information technology industry specifically and in other industries generally. Goldman Sachs also performed such other studies and analyses that it considered appropriate. Goldman Sachs relied upon the accuracy and completeness of all of the financial and other information discussed with or reviewed by it and assumed such accuracy and completeness for purposes of rendering its opinion. In that regard, Goldman Sachs assumed, with the consent of the Allscripts board of directors, that the forecasts for Allscripts and Channelhealth prepared by the management of Allscripts and Channelhealth and the synergies have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of Allscripts, and that such synergies will be realized in the amounts and the time periods contemplated thereby. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities of Allscripts, Channelhealth, IDX or any of their subsidiaries. No evaluation or appraisal of the assets and liabilities of Allscripts, Channelhealth, IDX or any of their subsidiaries was furnished to Goldman Sachs. Goldman Sachs relied upon the assumption that the strategic alliance agreement and the stock rights and restrictions agreement, when entered into by New Allscripts and IDX, will be in the forms attached as Exhibit D and Exhibit E to the merger agreement, respectively. The following is a summary of the material financial analyses used by Goldman Sachs in connection with providing its July 13, 2000 written opinion to the Allscripts board of directors. Some of the summaries of the financial analyses include information presented in tabular format. In order to more fully understand the financial analyses used by Goldman Sachs, the tables must be read together with the full text of each summary. The tables alone are not a complete description of Goldman Sachs' financial analyses. Selected Transactions Analysis Goldman Sachs analyzed certain information relating to selected business combinations in the healthcare information technology industry announced in 2000. This analysis demonstrates how some financial data about the merger compares to that of recent transactions in the healthcare information technology industry. Goldman Sachs compared the following transactions: . Royal Philips Electronics' transaction with MedQuist, Inc. announced in May 2000; . Siemens Corp.'s transaction with Shared Medical Systems Corporation announced in May 2000; 40

. MedicaLogic, Inc.'s transaction with Medscape, Inc. announced in February 2000; . Healtheon/WebMD Corp.'s transaction with OnHealth Network Company announced in February 2000; . Healtheon/WebMD Corp.'s transaction with Medical Manager Corporation announced in February 2000; and . Healtheon/WebMD Corp.'s transaction with CareInsite, Inc. announced in February 2000. Goldman Sachs calculated and compared for each of the selected transactions levered consideration as a multiple of: . latest twelve months' revenues; . latest twelve months' earnings before interest, taxes, depreciation and amortization, sometimes referred to as EBITDA; and . latest twelve months' earnings before interest and taxes, sometimes referred to as EBIT. Goldman Sachs also calculated and compared for each of the selected transactions equity as a multiple of latest twelve months' net income, using metrics and shares outstanding as of the transaction announcement date. The following tables present the results of this analysis. Transaction Value Ranges for the as a Multiple of Selected Transactions Median ----------------- --------------------- ------ Latest Twelve Months' Revenues............... 1.7x-1232.6x 44.9x Latest Twelve Months' EBITDA................. 11.4x-121.0x 20.0x Latest Twelve Months' EBIT................... 15.7x-269.9x 25.3x Ranges for the Equity Multiple of Selected Transactions Median ------------------ --------------------- ------ Latest Twelve Months' Net Income............. 26.0x-294.7x 39.9x Discounted Cash Flow Analysis Goldman Sachs performed a discounted cash flow analysis to determine the theoretical enterprise value of Channelhealth utilizing its management projections, which were refined and approved by Allscripts management. Goldman Sachs applied discount rates ranging from 15.0% to 25.0% and terminal value multiples of estimated 2004 EBITDA ranging from 5.0x to 10.0x. The various ranges for discount rates and terminal value multiples were chosen by Goldman Sachs based upon theoretical analyses of cost of capital ranges that could be applicable. Based on these discount rates and terminal value multiples, Goldman Sachs derived theoretical enterprise values ranging from: . $127.4 million to $389.5 million. Goldman Sachs also performed a discounted cash flow analysis to determine the theoretical value of the revenue synergies that might result from the transaction utilizing Allscripts' management projections. Goldman Sachs applied discount rates ranging from 15.0% to 20.0% and terminal value multiples of estimated 2010 EBITDA ranging from 6.0x to 10.0x. The various ranges for discount rates and terminal value multiples were chosen by Goldman Sachs based upon theoretical analyses of cost of capital ranges that could be applicable. Based on these discount rates and terminal value multiples, Goldman Sachs derived theoretical revenue synergies values ranging from: . $158.4 million to $358.5 million. 41

Selected Companies Analysis Goldman Sachs reviewed and compared financial information of Channelhealth to corresponding financial information, ratios and public market multiples for selected publicly traded healthcare information technology Internet companies. Goldman Sachs selected the following companies for comparison because they are publicly traded companies with certain operations that for purposes of analysis may be considered similar to certain operations of Channelhealth: The selected publicly traded healthcare information technology Internet companies consisted of: . Allscripts, Inc.; . Healtheon/WebMD Corp. (not pro forma for acquisitions of Envoy, CareInsite, Medical Manager and OnHealth); . MedicaLogic/Medscape, Inc.; and . The TriZetto Group, Inc. (pro forma for acquisition of ERISCO). Goldman Sachs calculated and compared various financial multiples and ratios for the selected companies based on financial data as of July 10, 2000, estimated 2000 revenue data primarily based on Goldman Sachs research and estimated 2001 revenue data primarily based on Institutional Broker's Estimate System, sometimes referred to as IBES, and Wall Street research (estimated 2000 and 2001 revenue data for Allscripts based on its management projections as of June 2000). The multiples for the selected companies were calculated using closing per share prices as of July 10, 2000. With respect to each of the selected healthcare information technology companies, Goldman Sachs considered: . estimated 2000 and estimated 2001 revenue multiples; and . IBES long-term growth rates. The results of these analyses are summarized in the following charts. Revenue Multiple -------------------- IBES LT Selected Companies 2000E 2001E Growth Rate ------------------ ---------- --------- ----------- Selected HCIT Internet Companies Median................................. 7.1x 4.4x 49.3% Range.................................. 5.3x-15.1x 1.5x-7.8x 45.0%-75.0% Pro-Forma Merger Analysis Goldman Sachs prepared a pro forma analysis of the financial impact of the merger using Allscripts management estimates for Allscripts and Channelhealth. Goldman Sachs analyzed, assuming synergies projected by Allscripts management, on a pro forma basis: . the accretion or dilution to cash earnings per share of the common stock of the combined company for each of the years 2001 and 2002. The analysis indicated that the proposed transaction would be dilutive to cash EPS in estimated year 2001 and accretive to cash EPS in estimated year 2002. Contribution Analysis Goldman Sachs reviewed historical and estimated future operating and financial information, including, among other things, revenues and gross profit, for Allscripts, Channelhealth and the pro forma combined entity resulting from the merger based on Allscripts' and Channelhealth's management projections. A contribution 42

analysis demonstrates the parties' respective historical and projected contributions, on a percentage basis, to certain income statement items of the combined company and compares such contributions to the parties' stockholders' relative equity interests in the combined company following the merger. Goldman Sachs analyzed the relative income statement contribution of Allscripts and Channelhealth to the combined company on a pro forma basis based on financial data and on the assumptions provided to Goldman Sachs by Allscripts and Channelhealth managements for estimated years 2000 through 2003 and for estimated years 2001 through 2003 with 50% synergies. Allscripts Contribution ------------ Revenues 2000E....................... 90.9% 2001E....................... 87.3% 2002E....................... 80.6% 2003E....................... 74.0% 2001E + 50% Synergies....... 75.1% 2002E + 50% Synergies....... 64.2% 2003E + 50% Synergies....... 59.0% Gross Profits 2000E.......................

Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs' opinion. In arriving at its fairness determination, Goldman Sachs considered the results of each of these analyses in their totality. No company or transaction used in the above analyses as a comparison is directly comparable to Channelhealth or the merger. The analyses were prepared for purposes of Goldman Sachs' providing its opinion to Allscripts' board of directors as to the fairness from a financial point of view of the merger consideration to be paid to the holders of Channelhealth common stock by Allscripts and do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. These analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their advisors. As described above, Goldman Sachs' opinion to Allscripts' board of directors was one of many factors taken into consideration by Allscripts' board of directors in making its determination to approve the merger agreement. The terms of the merger, including the merger consideration, were determined through arm's-length negotiations between Allscripts, IDX and Channelhealth. This summary is not a complete description of the analysis performed by Goldman Sachs and is qualified by reference to the written opinion of Goldman Sachs set forth in Annex B. Goldman Sachs, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. Allscripts selected Goldman Sachs as its financial advisor because it is 43

a nationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Goldman Sachs is familiar with Allscripts, having provided certain investment banking services to Allscripts from time to time, including having acted as managing underwriter of the initial public offering of Allscripts common stock on July 23, 1999 and having acted as managing underwriter of the public offering of Allscripts common stock on March 6, 2000. In addition, Goldman Sachs has acted as Allscripts' financial advisor in connection with, and has participated in certain of the negotiations leading to, the merger agreement. Goldman Sachs provides a full range of financial advisory and securities services and, in the course of its normal trading activities, may from time to time effect transactions and hold securities, including derivative securities, of Allscripts or IDX for its own account and for the accounts of customers. Pursuant to a letter agreement dated May 9, 2000, Allscripts engaged Goldman Sachs to act as its financial advisor in connection with the possible acquisition of all or a portion of the stock or assets of Channelhealth. Pursuant to the terms of the letter agreement, Allscripts has agreed to pay Goldman Sachs a fee in an amount customary for similar transactions upon consummation of the merger. Allscripts has agreed to reimburse Goldman Sachs for its reasonable out-of-pocket expenses, including attorney's fees, and to indemnify Goldman Sachs against certain liabilities, including certain liabilities under the federal securities laws. Interests of Certain Persons in the Transaction In considering the recommendation of the Channelhealth board of directors with respect to the merger agreement, Channelhealth stockholders should be aware that some members of the management of Channelhealth and the board of directors of Channelhealth have interests in the Channelhealth merger that may be different from, or in addition to, the interests of the other Channelhealth stockholders generally. New Allscripts Board Of Directors Richard E. Tarrant, Channelhealth's current Chairman of the Board, Chief Executive Officer and President, will be appointed to the New Allscripts board of directors to serve initially as the board's sole non-executive Vice Chairman. For information about the benefits to be received by New Allscripts directors, see "Management of New Allscripts--Directors--Compensation of Directors" and for information about the circumstances in which IDX remains entitled to appoint a designee to the New Allscripts board and Mr. Tarrant remains entitled to serve as the board's sole non-executive Vice Chairman, see "The Related Transaction Agreements--The Stock Rights and Restrictions Agreement--New Allscripts Board of Directors." IDX In connection with the mergers, 2,771,009 shares of Channelhealth common stock will be returned to Channelhealth by IDX pursuant to the Channelhealth/IDX asset purchase agreement in exchange for certain assets, including the "eCommerce Channel" and certain components of the "Patient Channel," from Channelhealth. In addition, upon completion of the mergers, IDX will enter into a 10-year strategic alliance agreement with New Allscripts and a cross license agreement with Channelhealth. The material terms of the asset purchase agreement are summarized in "The Merger Agreement--Channelhealth/IDX Asset Purchase Agreement," and the material terms of the strategic alliance agreement and the amended and restated cross license and software maintenance agreement are summarized in "The Related Transaction Agreements." Employment Agreement In connection with the mergers, New Allscripts will enter into an employment agreement with Pamela Pure, currently Channelhealth's Vice President and Chief Operating Officer, with a term of three years and a renewal option on terms agreeable to New Allscripts and Ms. Pure. Under the agreement, Ms. Pure will receive an annual salary of $210,000, plus other specified benefits for serving as President of Channelhealth. Ms. Pure will also receive an annual performance bonus of up to $73,500, with the exact amount to be determined by Allscripts' Chief Executive Officer and its President. The employment agreement also provides for the grant to 44

Ms. Pure of options to purchase [ ] shares of New Allscripts common stock at an exercise price of $[ ] per share. These options are in addition to the New Allscripts stock options into which the Channelhealth stock options currently held by Ms. Pure will be converted pursuant to the merger agreement. New Allscripts' employment agreement with Ms. Pure will also provide that if she is terminated other than for "cause" or if she resigns as President of Channelhealth for "good reason," she will receive severance pay in an amount equal to one year's salary. In the event Ms. Pure resigns her employment with New Allscripts other than for good reason or her employment is terminated for cause, she will not be entitled to a severance benefit. A termination by Ms. Pure of her employment agreement for good reason means a termination by her following: . an intentional, willful and material failure of New Allscripts to meet its obligations in any material respect under the employment agreement, which remains uncured one week after Ms. Pure has provided written notice of such failure; . a substantial adverse diminution in the nature or status of Ms. Pure's responsibilities with New Allscripts; or . a requirement that Ms. Pure relocate her residence to a location greater than 100 miles from her then current residence without her consent. A termination by New Allscripts of Ms. Pure's employment for cause means a termination by New Allscripts following: . her willful or grossly negligent failure to perform her duties and obligations under the employment agreement; . her commission of acts of gross misconduct that materially impair the goodwill or business of New Allscripts or cause material damage to its property, goodwill or business; . her conviction of a felony involving moral turpitude; or . her violation of law in connection with her employment in a manner that is materially injurious to New Allscripts, monetarily or otherwise. The employment agreement will also include provisions that restrict Ms. Pure during the term of her employment with New Allscripts and for one year thereafter from (1) conspiring with other New Allscripts employees to engage in or have an interest in "directly competitive" businesses, (2) working for or having an interest in "directly competitive" businesses (subject to her right to own up to 2% of a publicly traded entity), (3) soliciting the services of or hiring other New Allscripts employees or (4) contacting or soliciting New Allscripts' customers for the purpose of selling products or services to them that are the same as or substantially similar to the products or services offered by New Allscripts. Severance Agreements In connection with the mergers, New Allscripts will enter into severance agreements with certain specified Channelhealth management employees. The agreement will provide that upon a termination of the employee's employment with New Allscripts prior to the first anniversary date following completion of the merger transactions for any reason other than for cause, the employee will receive a cash severance payment equal to one-half of his or her annual salary. A termination by New Allscripts of an employee's employment for cause means a termination by New Allscripts following: . the employee's refusal or willful failure to perform the duties and obligations of his or her employment in any material respect that remains uncured 30 days following receipt of written notice of the refusal or failure from New Allscripts; 45

. the employee's commission of acts of gross misconduct that materially impair the goodwill or business of New Allscripts or cause material damage to its property, goodwill or business; . the employee's conviction of or entering of a plea of nolo contendere to a felony involving moral turpitude; or . the employee's violation of law in connection with his or her employment in a manner that is materially injurious to New Allscripts, monetarily or otherwise. The severance agreements will also include provisions that restrict the employee during the term of his or her employment with New Allscripts from (1) conspiring with other New Allscripts employees to engage in or have an interest in "directly competitive" businesses, (2) working for or having an interest in "directly competitive" businesses (subject to the employee's right to own up to 2% of a publicly traded entity), (3) soliciting the services of or hiring other New Allscripts employees or (4) contracting or soliciting New Allscripts' customers for the purpose of selling products or services to them that are the same as or substantially similar to the products or services offered by New Allscripts. Stock Options Upon completion of the mergers, New Allscripts will assume all outstanding Channelhealth stock options and convert each of those options into an option to purchase a number of shares of New Allscripts common stock equal to the number of shares of Channelhealth common stock subject to the Channelhealth option multiplied by 0.33730, which is the exchange ratio for converting Channelhealth common and preferred stock into New Allscripts common stock in the Channelhealth merger, at an exercise price equal to the former exercise price under the Channelhealth option divided by the 0.33730 exchange ratio. Generally these assumed options will be subject to the same terms and conditions, including with respect to expiration date, vesting and exercise provisions, as previously applied to the converted Channelhealth options. Upon completion of the merger transactions, there will be outstanding among these assumed options, options to purchase approximately 1,198,225 shares of Channelhealth common stock held by individuals other than Channelhealth employees, which will convert into options to purchase approximately 404,161 shares of New Allscripts common stock. Of those options, options to purchase approximately 396,909 shares of New Allscripts common stock will be fully vested and exercisable as of the date of grant at an exercise price of $29.65 (subject to adjustment for any stock split or reclassification) per share and will be exercisable at any time up to the tenth anniversary of the date of grant, and options to purchase approximately 7,252 shares of New Allscripts common stock will be exercisable ratably over four years at an exercise price of $29.65 (subject to adjustment for any stock split or reclassification) per share up to the tenth anniversary of the date of grant. Indemnification of Channelhealth Officers And Directors From and after the effective time of the mergers, New Allscripts and Allscripts agreed jointly and severally to guarantee, and to cause Channelhealth to maintain and perform, Channelhealth's existing indemnification obligations to present and former directors and officers of Channelhealth with respect to matters occurring through completion of the mergers to the extent required under Channelhealth's certificate of incorporation and by-laws in effect as of the date of the merger agreement and as permitted under and consistent with applicable law, for a period of not less than six years after the completion of the mergers. In addition, for six years from the effective time of the mergers, New Allscripts agreed to maintain in effect Channelhealth's current directors' and officers' liability insurance covering those persons who are currently covered by Channelhealth's directors' and officers' liability insurance policy, provided that in no event is New Allscripts required to expend for any one year an amount in excess of 200% of the annual premiums currently paid by Channelhealth for this insurance. However, if the annual premiums exceed the 200% cap, New Allscripts agreed to obtain a policy with the greatest coverage available for a cost not exceeding the cap. 46

Regulatory Approval Hart-Scott-Rodino Act Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which we refer to as the Hart-Scott-Rodino Act, and the regulations promulgated thereunder, transactions such as the mergers may not be consummated until notifications have been given and certain information has been furnished to the Antitrust Division of the United States Department of Justice and the Federal Trade Commission and specified waiting period requirements have expired or terminated. We have filed all appropriate notification and report forms with the Antitrust Division and the Federal Trade Commission with respect to the mergers, and the waiting period with respect to such filings terminated on August 23, 2000. Other Antitrust Other antitrust authorities may also bring legal action under state or federal antitrust laws. Such action could include seeking to enjoin the consummation of the mergers or seeking divestiture of certain assets of Allscripts or Channelhealth. Private parties may also seek to take legal action under the antitrust laws under certain circumstances. We cannot predict whether or not a challenge to the mergers on antitrust grounds will be made or, if such a challenge is made, what the result might be. Status of Regulatory Approvals and Other Information We have filed applications with all applicable domestic regulatory agencies and have taken, or will take, other appropriate action with respect to any requisite approvals or other action of any court, administrative agency or commission or other governmental authority or instrumentality, whose consent, approval, order or authorization, or with whom registration, declaration or filing of the merger agreement is required to consummate the mergers, subject to the provisions of the merger agreement. The merger agreement provides that the obligation of each of the parties to consummate the mergers is conditioned upon, among other things, the absence of any statute, rule, regulation, order or decree of any governmental body or authority prohibiting consummation of the mergers. We cannot predict whether or not any governmental agency will approve or take any other required action with respect to the mergers, and, if approvals are received or action is taken, whether or not those approvals or action will be conditioned upon matters that would cause us to abandon the mergers. In addition, we cannot predict whether or not an action will be brought challenging such approvals or action, or, if such challenge is made, what the result might be. We are not aware of any material governmental approvals or actions that may be required for consummation of the merger transactions other than as described above. Accounting Treatment New Allscripts will account for the merger transactions under the purchase method of accounting, with Allscripts treated as the acquiror. As a result, New Allscripts will record the assets and liabilities of Allscripts at historical amounts, without restatement to fair values. New Allscripts will record the assets (including both tangible and identifiable intangible assets) and liabilities of Channelhealth at their estimated fair values at the date of the mergers, with the excess of the purchase price over the sum of such fair values recorded as goodwill. For this purpose, the purchase price is based upon the market capitalization of Allscripts using an average trading price of Allscripts common shares for a period immediately before and after the announcement of the merger transactions. See "New Allscripts Consolidated Condensed Pro Forma Financial Statements." United States Federal Income Tax Consequences The following discussion is a general summary of the material federal income tax consequences of the Allscripts and Channelhealth mergers and is based on the Internal Revenue Code of 1986, as amended, the final, proposed and temporary Treasury Regulations promulgated thereunder, administrative rulings and interpretations, and judicial decisions, in each case as in effect as of the date hereof. All of the foregoing are subject to change at any time, possibly with retroactive effect. The discussion set forth below does not address all aspects of federal income taxation that may be relevant to a stockholder in light of such stockholder's particular circumstances or to stockholders subject to special rules under the federal income tax laws, such as 47

non-United States persons, financial institutions, tax-exempt organizations, insurance companies, dealers in securities or stockholders who acquired their Allscripts or Channelhealth shares pursuant to the exercise of employee stock options or otherwise as compensation, nor any consequences arising under the laws of any state, local or foreign jurisdiction. This discussion assumes that holders of Allscripts common stock and holders of Channelhealth common stock or preferred stock hold their respective shares of stock as capital assets within the meaning of Section 1221 of the Internal Revenue Code. None of Allscripts, New Allscripts, Channelhealth or IDX intends to secure a ruling from the Internal Revenue Service with respect to the tax consequences of the merger transactions. Weil, Gotshal & Manges LLP has delivered to Allscripts an opinion dated [ ], 2000, a copy of which is filed as Exhibit 8.1 to the registration statement filed by New Allscripts, to the effect that (based upon and subject to the facts, representations, covenants and assumptions set forth therein) the Allscripts merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. It is a condition to the obligation of Allscripts to complete the merger transactions that Allscripts shall have received an opinion, dated the date of completion of the mergers, from Weil, Gotshal & Manges LLP to the effect that the Allscripts merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code or an exchange under Section 351 of the Internal Revenue Code. Hale and Dorr LLP has delivered to IDX an opinion dated [ ], 2000, a copy of which is filed as Exhibit 8.2 to the registration statement filed by New Allscripts, to the effect that (based upon and subject to the facts, representations, covenants and assumptions set forth therein) the Channelhealth merger will be treated as an exchange under Section 351 of the Internal Revenue Code. The opinions of Weil, Gotshal & Manges LLP and Hale and Dorr LLP, filed as exhibits to the registration statement filed by New Allscripts, are based on facts existing at the date hereof and at the date of completion of the mergers. In rendering such opinions, Weil, Gotshal & Manges LLP and Hale and Dorr LLP have assumed the absence of changes in existing facts and have relied on representations and covenants made by Allscripts, New Allscripts, Channelhealth, IDX and others. The opinion of Weil, Gotshal & Manges LLP dated the date of the completion of the mergers will be based on facts existing at such date and will also rely on representations and covenants made by Allscripts, New Allscripts, Channelhealth, IDX and others. Federal Income Tax Implications to Allscripts Stockholders Based on the advice of Weil, Gotshal & Manges LLP, counsel to Allscripts, assuming the Allscripts merger is treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code: . no gain or loss will be recognized for federal income tax purposes by a holder of Allscripts common stock upon the exchange of Allscripts common stock for New Allscripts common stock pursuant to the Allscripts merger; . a stockholder's aggregate tax basis in New Allscripts common stock received pursuant to the Allscripts merger will be the same as such stockholder's aggregate tax basis in the Allscripts common stock that was exchanged therefor; and . a stockholder's holding period in New Allscripts common stock received pursuant to the Allscripts merger will include the period during which such stockholder held the Allscripts common stock exchanged therefor. Federal Income Tax Implications to Channelhealth Stockholders Based on the advice of Hale and Dorr LLP, counsel to IDX, assuming the Channelhealth merger is treated as an exchange under Section 351 of the Internal Revenue Code and that the only consideration received by the Channelhealth stockholders is New Allscripts common stock, cash in lieu of a fractional share of New Allscripts common stock and earnout shares: . no income, gain or loss will be recognized for federal income tax purposes by a holder of Channelhealth stock upon the exchange of Channelhealth common or preferred stock for New Allscripts common stock pursuant to the Channelhealth merger, except as described below with respect to cash received in lieu of 48

a fractional share of New Allscripts common stock and the portion of the earnout shares that is characterized as interest for federal income tax purposes; . a stockholder's aggregate tax basis in New Allscripts common stock received pursuant to the Channelhealth merger (excluding the portion of the earnout shares which will be characterized as interest for federal income tax purposes as described below) will be the same as such stockholder's aggregate tax basis in the Channelhealth stock exchanged therefor; . a stockholder's holding period of the New Allscripts common stock received pursuant to the Channelhealth merger (excluding the portion of the earnout shares which will be characterized as interest for federal income tax purposes as described below) will include the period during which such stockholder held the Channelhealth common and preferred stock exchanged therefor; . cash received by holders of Channelhealth stock in lieu of a fractional share of New Allscripts common stock will be treated as received in exchange for such fractional share interest, and capital gain or loss will be recognized for federal income tax purposes, measured by the difference between the amount of cash received and the portion of the basis of the Channelhealth stock allocable to the fractional share interest, and such capital gain or loss will be long-term if the Channelhealth stock had been held for more than one year at the time of the Channelhealth merger; and . a portion of the earnout shares received pursuant to the Channelhealth merger will be characterized as interest and taxable to the Channelhealth stockholders as ordinary income for federal income tax purposes if and when such holder receives the earnout shares. A holder of Channelhealth stock who receives or may receive earnout shares and who sells less than all of the shares he, she or it received or may receive in the Channelhealth merger should consult his, her or its tax advisor as to the proper method of determining the basis and holding period of the shares that are sold. The above discussion does not apply to stockholders who exercise appraisal rights. A holder of Channelhealth stock who exercises appraisal rights with respect to the Channelhealth merger and receives cash for shares of Channelhealth stock will generally recognize capital gain (or loss) measured by the difference between the amount of cash received and the stockholder's basis in those shares. The capital gain or loss will be long-term capital gain or loss if the holder's holding period for the shares is more than one year. HOLDERS OF ALLSCRIPTS COMMON STOCK, CHANNELHEALTH COMMON STOCK AND CHANNELHEALTH PREFERRED STOCK ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTION, WHICH MAY VARY FOR HOLDERS IN DIFFERENT TAX SITUATIONS, INCLUDING THE APPLICABILITY AND EFFECT OF FOREIGN, STATE, LOCAL AND OTHER TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX LAWS. Stock Market Listing New Allscripts will apply to authorize the New Allscripts common stock for quotation on the Nasdaq National Market and anticipates that its shares will trade on the Nasdaq National Market, upon official notice of issuance, under the symbol "MDRX." Federal Securities Laws Consequences All shares of New Allscripts common stock received by Allscripts stockholders and Channelhealth common and preferred stockholders upon completion of the merger transactions will be freely transferable under federal securities laws, except that shares of New Allscripts common stock received by persons who are deemed to be "affiliates" (as such term is defined under the Securities Act of 1933, as amended) of Allscripts or Channelhealth prior to the consummation of the merger transactions may be resold by them only in transactions permitted by the resale provisions of Rule 145 promulgated under the Securities Act (or Rule 144 49

in the case of such persons who become affiliates of New Allscripts) or as otherwise permitted under the Securities Act. Persons who may be deemed to be affiliates of Allscripts or Channelhealth generally include individuals or entities that control, are controlled by or are under common control with such party and may include certain officers and directors of such party as well as principal stockholders of such party. In addition, pursuant to the stock rights and restrictions agreement to be entered into between New Allscripts and IDX upon completion of the merger transactions, IDX will agree to certain restrictions on the transferability of the shares of New Allscripts common stock received by IDX upon consummation of the merger transactions. See "The Transaction Agreements--Stock Rights and Restrictions Agreement." Any shares of New Allscripts common stock issued pursuant to the earnout clause of the merger agreement will be issued in reliance upon the exemption from the registration requirements of the Securities Act afforded by Rule 506 of the Securities and Exchange Commission's Regulation D. However, if any earnout shares are issued, within five business days of issuance New Allscripts will file a non-exclusive resale "shelf" registration statement to permit the unrestricted resale of those shares to the public on a continuous basis. New Allscripts will use its best efforts to cause the resale shelf registration statement to be declared effective by the Securities and Exchange Commission as soon as practicable after filing and to cause the registration statement to remain effective for a period of two years or such earlier time as all of the earnout shares covered by the registration statement have been sold. Appraisal Rights The following summary of the provisions of Section 262 of the Delaware General Corporation Law is not intended to be a complete statement of these provisions and is qualified in its entirety by reference to the full text of Section 262 of the Delaware General Corporation Law, a copy of which is attached to this proxy statement/prospectus as Annex C and is incorporated into this summary by reference. Under Delaware law, Allscripts common stockholders are not entitled to appraisal rights in connection with the merger. However, holders of Channelhealth common and preferred stock are entitled to appraisal rights under Delaware law. A holder of Channelhealth common or preferred stock who elects to exercise appraisal rights must satisfy each of the following conditions: (1) such holder must deliver to Channelhealth, before the taking of the vote with respect to the merger agreement, written notice of his or her intention to demand payment of the fair value of his or her shares (this written notice must be in addition to and separate from any proxy or vote against the merger agreement; neither voting against adoption nor a failure to vote for the merger agreement will constitute such a notice); and (2) such holders must not vote in favor of adoption of the merger agreement (a failure to vote will satisfy the requirement, but a vote in favor of adoption of the merger agreement, by proxy or in person, will constitute a waiver of such holder's appraisal rights and will nullify any previously filed written notice of intent to demand payment). A stockholder who fails to comply with either of these conditions will have no appraisal rights with respect to his or her shares. A stockholder who elects to exercise his or her appraisal rights should mail or deliver his or her written notice to: Channelhealth Incorporated, 25 Green Mountain Drive, Burlington, Vermont 05403, Attention: Secretary. Such notice must be executed by, or with the consent of, the holder of record. The notice must identify the stockholder and indicate the intention of such stockholder to demand payment of the fair value of his or her shares. In the notice, the stockholder's name should be stated as it appears on his or her stock certificate(s). If the shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, the demand should be executed in that capacity, and if the shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including one or more joint owners, may execute a demand for appraisal on behalf of a record holder; however, in the demand the agent must identify the record owner or owners and expressly disclose that the agent is executing the demand as an agent for the record owner or owners. A record holder such as a broker who holds shares as nominee for several beneficial owners may exercise appraisal rights for the shares held for one or more beneficial owners and not exercise rights for the shares held for other beneficial owners. In this case, the written demand should state the number of shares for which appraisal rights 50

are being demanded. When no number of shares is stated, the demand will be presumed to cover all shares held of record by the broker or nominee. If the merger is completed, each holder of Channelhealth common or preferred stock who complies with (1) and (2) above will be entitled to be paid for his, her or its shares of Channelhealth common or preferred stock by the surviving corporation the fair value in cash of the shares of Channelhealth common or preferred stock. The Delaware Court of Chancery will appraise the shares, determining the fair value arising from the consummation of the merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be fair value. In determining such fair value, the court may take into account all relevant factors and upon such determination will then direct the payment of the fair value of the shares, together with any interest, to the holders of Channelhealth common or preferred stock who have perfected their appraisal rights. The shares of Channelhealth common or preferred stock with respect to which holders have perfected their appraisal rights in accordance with Section 262 and have not effectively withdrawn or lost their appraisal rights are referred to in this proxy statement/prospectus as the "dissenting shares." Stockholders considering seeking appraisal for their shares should note that the fair value of their shares determined under Section 262 could be more, the same or less than the consideration they would receive pursuant to the merger agreement if they did not seek appraisal of their shares. The costs of the appraisal proceeding may be determined by the court and allocated among the parties as the court deems equitable under the circumstances. Upon application of a stockholder, the court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all shares entitled to appraisal. In the absence of such determination or assessment, each stockholder bears his or her own expenses. Within ten days after the effective date of the mergers, Channelhealth, as the surviving corporation in the merger, must mail notice to all stockholders who have complied with (1) and (2) above notifying such stockholders of the effective date of the Channelhealth merger. Within 120 days after the effective date, holders of Channelhealth common or preferred stock may file a petition in the Delaware court of Chancery for the appraisal of their shares, although they may, within 60 days of the effective date, withdraw their demand for appraisal and accept the merger consideration to which he or she would have otherwise been entitled. At the hearing on such petition, the Court will determine the stockholders who have perfected their appraisal rights. The Court may require the holders of dissenting shares to submit their stock certificates to the Register in Chancery for notation thereon of the pending of appraisal proceedings; the failure of a stockholder to comply with such direction may result in the Court dismissing the proceedings as to such stockholder. In addition, within 120 days of the effective date, the holders of dissenting shares may, upon written request, receive from Channelhealth as statement setting forth the aggregate number of shares not voted in favor of adopting the merger agreement and with respect to which demands for appraisals have been received and the aggregate number of holders of such shares. If any holder of Channelhealth common or preferred stock who demands appraisal of his, her or its shares under Section 262 fails to perfect, or effectively withdraws or loses the right to appraisal, his, her or its shares will be converted into a right to receive a number of New Allscripts common shares calculated in accordance with the terms of the merger agreement. Dissenting shares lose their status as dissenting shares if: . the merger is abandoned; . the stockholder seeking appraisal rights fails to make a timely written demand for appraisal; . neither Channelhealth nor the stockholder files a complaint or intervenes in a pending action within 120 days after the effective date of the merger; or . the stockholder delivers to Channelhealth, as the surviving corporation, within 60 days of the effective date of the merger, or thereafter with Channelhealth's approval, a written withdrawal of the 51

stockholder's demand for appraisal of the dissenting shares, although no appraisal proceeding in the Delaware Court of Chancery may be dismissed as to any stockholder without the approval of the court. Failure to follow the steps required by Section 262 for perfecting appraisal rights may result in the loss of appraisal rights, in which event a Channelhealth stockholder will be entitled to receive the consideration with respect to the holder's dissenting shares in accordance with the merger agreement. In view of the complexity of the provisions of Section 262, Channelhealth stockholders are encouraged to consult with their own advisors regarding these appraisal rights. 52

THE MERGER AGREEMENT This section describes the material provisions of the merger agreement. Because the description of the merger agreement contained in this document is a summary, it does not contain all of the information that is in the merger agreement. A copy of the merger agreement is attached as Annex A to this document and you are encouraged to read the full text of the merger agreement before you decide how to vote. The Merger At the effective time of the mergers, Bursar will merge with and into Allscripts and Bursar No. 2 will merge with and into Channelhealth. Allscripts and Channelhealth, which will be the surviving corporations in these mergers, each will become a separate wholly-owned subsidiary of New Allscripts. The closing date of the mergers will occur no later than the second business day following the date on which all conditions to the mergers, other than those conditions that by their nature are to be satisfied at the closing, have been satisfied or waived, unless the parties agree on another time. As soon as practicable on or after the closing date of the merger, certificates of merger will be filed with the Secretary of State of the State of Delaware. The effective time of the mergers will be the time the certificates of merger are filed with the Secretary of State of the State of Delaware or at a later time as the parties may agree and specify in the certificates of merger. The parties currently anticipate that the merger will be completed shortly after the Channelhealth and Allscripts special meetings, assuming their respective stockholders adopt and approve at these meetings the merger and the issuance of New Allscripts common shares in connection with the Channelhealth merger and all other conditions to the mergers have been satisfied or waived. Merger Consideration Exchange Ratios At the effective time of the mergers, . each share of Channelhealth common stock and each share of Channelhealth preferred stock issued and outstanding immediately before the effective time of the merger (other than shares of Channelhealth stock held by Channelhealth, which will be canceled and retired without the right to receive any consideration in exchange therefor and shares held by persons who have perfected appraisal rights) will be converted into the right to receive 0.33730 New Allscripts common shares; and . each issued and outstanding share of Allscripts common stock will be converted into the right to receive one New Allscripts common share. Fractional Shares Certificates for fractional New Allscripts common shares will not be issued in the Channelhealth merger. Channelhealth stockholders who would otherwise receive fractional shares will instead be entitled to receive a cash payment equal to the value of these fractional share interests. Earnout Earnout Shares. In further consideration of the Channelhealth merger, on or before March 31, 2003, New Allscripts agreed to issue additional shares of New Allscripts common stock to the former Channelhealth stockholders if the following conditions are satisfied: . If for the period from January 1, 2002 through December 31, 2002, which we refer to as the earnout period, New Allscripts or any of its affiliates recognizes revenues from sales generated from the Channelhealth service lines set forth on a schedule to the merger agreement, which we refer to as gross qualifying revenues, of greater than or equal to $180 million but less than or equal to $210 million, New Allscripts will issue an additional .04131 shares of its common stock for each share of Channelhealth common or preferred stock held at the effective time of the mergers; 53

. If during the earnout period, New Allscripts either (1) recognizes gross qualifying revenues in excess of $210 million or (2) sells, transfers or otherwise disposes of, or causes any of its affiliates to sell, transfer or otherwise dispose of all or substantially all of its business or intellectual property related to physician-focused, Internet-based services that automate clinical, financial and administrative functions involved in the healthcare delivery process, New Allscripts will issue an additional 0.06278 shares of its common stock for each share of Channelhealth common or preferred stock held at the effective time of the mergers; and . If during the earnout period, New Allscripts recognizes gross qualifying revenues of less than $180 million, New Allscripts will not issue any additional shares of its common stock. No Channelhealth stockholder will be entitled to receive any earnout shares otherwise issuable on account of any share of Channelhealth stock with respect to which appraisal rights shall have been demanded and perfected and not effectively withdrawn or forfeited prior to the effective time of the merger. Registration of Earnout Shares. Any shares of New Allscripts common stock issued pursuant to the earnout clause of the merger agreement will be, and the right to receive such shares is being, issued in reliance upon the exemption from the registration requirements of the Securities Act afforded by Rule 506 of the Securities and Exchange Commission's Regulation D. If any earnout shares are issued, within five business days of issuance New Allscripts will file a non-exclusive resale "shelf" registration statement to permit the unrestricted resale of those shares to the public on a continuous basis. New Allscripts will use its best efforts to cause the resale shelf registration statement to be declared effective by the Securities and Exchange Commission as soon as practicable after filing and to cause the registration statement to remain effective until the second anniversary of the filing of the registration statement or such earlier time as all of the earnout shares covered by the registration statement have been sold. New Allscripts may suspend sales of earnout shares pursuant to the registration statement during any period when New Allscripts is involved in discussions concerning or is otherwise engaged in any material financing, offering, investment, acquisition or divestiture transaction if New Allscripts determines that amending the registration statement or supplementing the related resale prospectus would be required to permit sales to continue, but the disclosure would interfere with the transaction or other business purpose giving rise to the need for the amendment or supplement. However, New Allscripts agreed to use its reasonable efforts to permit sales of earnout shares pursuant to the resale shelf registration statement for at least 180 days during any 360-day period. Any earnout shares issued to IDX by New Allscripts will be subject to the stock rights and restrictions agreement to be entered into between New Allscripts and IDX upon completion of the merger transactions. See "The Related Transaction Agreements--Stock Rights and Restrictions Agreement." Exchange Procedures As soon as reasonably practicable after the effective time of the mergers, an exchange agent will mail a letter of transmittal to each holder of record of Channelhealth or Allscripts stock certificates. This letter of transmittal must be used in surrendering Channelhealth or Allscripts stock certificates to the exchange agent for cancellation. Upon surrender of a Channelhealth or Allscripts stock certificate for cancellation, together with a duly executed letter of transmittal and any other documents that the exchange agent may reasonably require, the holder of the Channelhealth or Allscripts stock certificate will be entitled to receive in exchange therefor (1) a New Allscripts certificate representing the number of whole New Allscripts common shares that the holder has the right to receive, (2) in the case of Channelhealth holders, a check representing the amount of cash payable in lieu of any fractional New Allscripts common shares, if any and (3) unpaid dividends and distributions, if any, that the holder has the right to receive pursuant to the merger agreement, after giving effect to any required withholding tax. NEITHER CHANNELHEALTH NOR ALLSCRIPTS STOCKHOLDERS SHOULD SEND IN THEIR CHANNELHEALTH OR ALLSCRIPTS STOCK CERTIFICATES UNTIL THEY RECEIVE THE LETTER OF TRANSMITTAL. In the event any certificates representing Channelhealth common stock or preferred stock or any certificates representing Allscripts common stock have been lost, stolen or destroyed, the exchange agent will 54

issue shares of New Allscripts common stock and, if applicable, cash in exchange for such lost, stolen or destroyed certificates upon the making of an affidavit of that fact by the owner of such certificates and delivery of a bond in a reasonable sum as indemnity against any claim that may be against New Allscripts or the exchange agent with respect to the certificates alleged to have been lost, stolen or destroyed. After the effective time of the mergers, each Channelhealth and Allscripts stock certificate, until surrendered and exchanged, will represent only the right to receive a certificate representing New Allscripts common shares and, in the case of Channelhealth stock certificates, cash in lieu of fractional shares, if any, and unpaid dividends and distributions, if any. Holders of Channelhealth and Allscripts stock certificates will not be entitled to receive any dividends or other distributions with respect to New Allscripts common shares declared or made by New Allscripts having a record date after the effective time of the mergers until the Channelhealth or Allscripts stock certificates are surrendered. Subject to applicable law, following surrender of the Channelhealth or Allscripts stock certificates, as the case may be, such dividends and distributions, if any, will be paid without interest. Accrued Liabilities Adjustment Following completion of the mergers, New Allscripts will cause Channelhealth to prepare a balance sheet as of the closing date, which shall be audited by Ernst & Young LLP, IDX's regular independent public accountants. To the extent there are accounts payable or other current and accrued liabilities, excluding only liabilities for taxes for which IDX is otherwise indemnifying New Allscripts pursuant to the merger agreement, reflected on the Channelhealth closing date balance sheet, IDX will make a payment to New Allscripts equal to that amount, which we refer to as the accrued liabilities adjustment. Channelhealth/IDX Asset Purchase Agreement Pursuant to the Channelhealth/IDX asset purchase agreement, Channelhealth agreed to assign, sell, convey, transfer and deliver to IDX, on or before the closing date for the merger transactions, the assets identified in that agreement and also on a schedule to the merger agreement in consideration of the return to Channelhealth of 2,771,009 shares of its common stock currently held by IDX. The merger agreement provides that these assets, which we refer to as the retained assets, are not included in the properties or assets of Channelhealth to be acquired by New Allscripts through the Channelhealth merger. Also in the merger agreement, IDX agreed to indemnify and hold harmless New Allscripts, Allscripts, Channelhealth and their respective directors, officers, employees, affiliates, agents, successors and assigns harmless from and against any and all losses, liabilities, obligations, claims, damages, costs and expenses arising out of or related to: . the ownership or operation of the business or properties comprising the retained assets; and . the authorization, approval, execution, delivery and performance of the Channelhealth/IDX asset purchase agreement. Representations and Warranties The merger agreement contains various representations and warranties made by IDX, Channelhealth and New Allscripts and Allscripts. The table below summarizes what the most important of these representations and warranties relate to and by which party they are made: Representation and New Allscripts Warranty as to: IDX Channelhealth and Allscripts - ------------------------------------------------------------------------------------------------ Capitalization of Channelhealth X X - ------------------------------------------------------------------------------------------------ Options, warrant, calls, rights, commitments or other agreements to issue, sell, redeem, transfer or otherwise dispose of Channelhealth securities; X voting agreements with respect to Channelhealth capital stock 55

Each of Channelhealth, Allscripts and New Allscripts have made representations and warranties as to corporate power and authority to do business and Channelhealth has further represented and warranted as to foreign qualifications to do business and the absence of any liens on its properties or assets. Each of Allscripts and IDX have represented and warranted as to fairness opinions to be received from their respective financial advisors. The representations and warranties contained in the merger agreement form the basis of certain conditions to the parties' obligations to complete the merger, and will survive the closing of the merger transactions, provided that any claims or actions with respect to representations and warranties will terminate unless by March 31, 2002 written notice of such claims is delivered or such actions are commenced by that date, except for Channelhealth's tax matters representations and warranties, which will survive the closing until 60 days after the expiration of the applicable tax statute of limitations. Covenants Each of the parties to the merger agreement has undertaken certain covenants in the merger agreement. The following summarizes the more significant of these covenants. Stockholders Meetings Subject to the terms and conditions of the merger agreement, Channelhealth and Allscripts agreed to submit the merger agreement for approval to their respective stockholders at a meeting to be duly held for that purpose. Board of Directors Covenant to Recommend Channelhealth and Allscripts have agreed that their respective boards of directors will recommend the approval of the merger agreement and authorize the merger and the other transactions contemplated by the merger agreement, and have otherwise agreed to use best efforts to obtain their respective stockholders' approval of the merger transactions. Operations of the Companies Pending Closing Channelhealth. Channelhealth and IDX have undertaken a series of covenants that impose restrictions on Channelhealth until either the effective time of the mergers or the termination of the merger agreement. In general, Channelhealth is required to conduct its business in the ordinary course and to use its commercially reasonable efforts to preserve its present business operations and organization and preserve its present relationship with the Channelhealth customers and suppliers identified on a schedule to the merger agreement.

Channelhealth Employee Matters From and after the effective time of the mergers, Channelhealth will continue the employment at will of the current Channelhealth employees at initially the same or greater rate of base pay as that at which they were employed immediately prior to the completion of the mergers. In addition, following completion of the mergers through December 31, 2001, which we refer to as the transition period, New Allscripts will provide those employees of Channelhealth with benefits that, in the aggregate, are substantially comparable to the benefits currently provided under Channelhealth's existing employee benefit plans, at no additional cost to the employees. For eligibility and vesting purposes with respect to Channelhealth or New Allscripts employee benefit plans covering Channelhealth employees after completion of the mergers, they will retain any credit for their past service under the existing Channelhealth employee benefit plans. Without limiting the foregoing, during the transition period, continuing Channelhealth employees will be provided with benefits under the New Allscripts plans that are no less favorable than the benefits provided to similarly situated employees of Allscripts. Continuing Channelhealth employees will be eligible to participate in the New Allscripts employee benefit plans without any evidence of insurability and without the application of any pre-existing physical or mental condition restrictions except to the extent applicable under the existing Channelhealth employee benefit plans, but counting expenditures made prior to the completion of the mergers for purposes of applying deductible, out-of-pocket maximums and other such matters. Treatment of Stock Options Channelhealth Options. Each outstanding option to purchase shares of Channelhealth common stock will be assumed by New Allscripts and converted into an option to purchase a number of New Allscripts common shares equal to 0.33730 multiplied by the number of shares of Channelhealth common stock that could have 59

been obtained immediately prior to the effective time of the mergers upon the exercise of the Channelhealth option, at an exercise price per share equal to (1) the exercise price per share of Channelhealth common stock purchasable pursuant to the Channelhealth stock option divided by (2) 0.33730. Assumption of Channelhealth Obligations; Form S-8. New Allscripts will assume the obligations of Channelhealth under the Channelhealth stock option plan. The other terms of the Channelhealth options and the plan under which they were issued, shall continue to apply in accordance with their terms. Promptly after the effective time of the mergers, and in any event within 30 days after the effective time, New Allscripts will file with the Securities and Exchange Commission a registration statement on Form S-8 or other appropriate form under the Securities Act to register the New Allscripts common shares issuable upon exercise of the Channelhealth options assumed by New Allscripts, and use its reasonable efforts to cause the registration statement to remain effective until the exercise or expiration of those options. Allscripts Employee Incentive Plans. The Allscripts Amended and Restated 1993 Stock Option Plan and each option outstanding under that plan, and each other outstanding award (including restricted stock, stock equivalents and stock units) under any employee incentive or benefit plans, programs or arrangements and non-employee director plans maintained by Allscripts as of the date of the merger agreement that provide for grants of equity-based awards will be amended or converted into a similar plan or instrument of New Allscripts without any adjustment as to the number of shares eligible for purchase or issuance or as to the exercise or purchase price. The other terms of each Allscripts option or award, and the plans or agreements under which they were issued, will be assumed by New Allscripts and will continue to apply in accordance with their terms. IDX Stock Options. IDX agreed that it will remain responsible for all of its obligations and rights with respect to any stock options held on the closing date of the mergers under IDX's stock option plan by any employees of Channelhealth. Upon completion of the merger transactions, all such stock options will vest. Reservation, Issuance and Listing of Shares. New Allscripts will (1) reserve for issuance the number of New Allscripts common shares that will become subject to the benefit plans, programs and arrangements referred to above, (2) issue the appropriate number of New Allscripts common shares pursuant to these plans, programs and arrangements, upon the exercise or maturation of rights existing thereunder on the effective time of the merger or thereafter granted or awarded and (3) take all actions necessary to authorize the New Allscripts common shares for quotation on the Nasdaq National Market. Proxy Statement/Prospectus; Registration Statement As promptly as practical after execution of the merger agreement, Allscripts and New Allscripts agreed to prepare and file with the Securities and Exchange Commission a proxy statement/prospectus and to use their commercially reasonable efforts to have the proxy materials cleared by the Securities and Exchange Commission and the registration statement of which the proxy materials will form a part declared effective by the Securities and Exchange Commission as promptly as practicable after filing. Allscripts and New Allscripts agreed: . to keep IDX and Channelhealth informed of any comments or correspondence received from the Securities and Exchange Commission with respect to the proxy materials and registration statement; . to cause all documents that Allscripts is required to file with the Securities and Exchange Commission to comply with all applicable legal requirements; and . to amend or supplement the registration statement and/or the proxy statement/prospectus if and as required. In connection with the preparation of the registration statement, each of IDX and Allscripts agreed to obtain for inclusion in the registration statement the opinion of their respective tax counsel concerning the federal income tax consequences of the Channelhealth merger to the stockholders of Channelhealth and the 60

Allscripts merger to the stockholders of Allscripts, respectively. Each of Hale and Dorr LLP and Weil, Gotshal & Manges LLP are permitted to require and rely on representations made by Allscripts, New Allscripts, Channelhealth, IDX and others in rendering their respective opinions. Listing of New Allscripts Shares and Earnout Shares Prior to the effective time of the merger, New Allscripts agreed to take all actions necessary to authorize the shares of New Allscripts common stock to be issued in the mergers and the earnout shares for quotation on the Nasdaq National Market, subject to official notice of issuance. Rule 144 New Allscripts agreed to file all reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time prior to the seventh anniversary of the effective time of the mergers, New Allscripts is not required to file such reports, it will, on the request of the former Channelhealth stockholders, make publicly available other information so long as is necessary to permit sales of its securities pursuant to Rule 144 promulgated under the Securities Act, and take such further action as the Channelhealth stockholders may reasonably request to enable the former Channelhealth stockholders to sell shares of New Allscripts common stock without registration under the Securities Act as provided by Rule 144. Allscripts Tax Covenant Prior to the effective time of the mergers, Allscripts undertook not to agree to all or substantially all of the material terms of a transaction that (1) would be integrated with the mergers for federal income tax purposes, which we refer to as an integrated transaction and (2) would cause the stockholders of Allscripts and the Channelhealth stockholders immediately before the mergers and any "integrated transferors" not to be in control (within the meaning of Section 368(c) of the Internal Revenue Code) of New Allscripts immediately after the mergers. For purposes of this covenant, an "integrated transferor" includes any person who receives shares of New Allscripts capital stock in an integrated transaction and would be treated as a transferor of property to New Allscripts in that transaction for purposes of Section 351 of the Internal Revenue Code. Repayment of Loans by IDX On or prior to the closing date for the merger transactions, any loans or other advances by Channelhealth to IDX or any of its affiliates (including interest) will be repaid to Channelhealth. Use of Names IDX agreed that upon completion of the mergers, New Allscripts and Channelhealth will have the sole right to use each of the following names, and that IDX will not and will not permit any of its affiliates to use any of these names or any variation or simulation of any of them in any business involving the provision of healthcare information and/or point-of-care clinical application or devices or any related business: . CHANNELPHARMACY . NOTEWORKS . CHANNELHEALTH . ORDERWORKS . CHANNELHEALTH.COM . PHARMACYCHANNEL . CHARGEWORKS . PHYSICIAN CHANNEL . DOCWORKS . PHYSICIAN HOMEBASE . KNOWLEDGE FOR LIFE . RESULTWORKS .

The foregoing restrictions will lapse if after completion of the mergers Channelhealth changes its name, or, with respect to a particular name, the restrictions will lapse if Channelhealth ceases to use that name in any of its businesses for a period of 12 consecutive months. Stock Rights and Restrictions Agreement At or prior to the effective time, New Allscripts and Allscripts agreed to take actions under the Delaware General Corporation Law or their respective certificates of incorporation or by-laws as may be required to enable New Allscripts to comply with its obligations under the stock rights and restrictions agreement to be entered into upon completion of the mergers between New Allscripts and IDX. See "The Related Transaction Agreements--Stock Rights and Restrictions Agreement." No Solicitation IDX has agreed that IDX, Channelhealth and their respective directors, officers, employees, representatives and agents: . other than in connection with the transactions contemplated by the merger agreement, will not, directly or indirectly, discuss, negotiate, authorize, recommend, propose or enter into any transaction involving a merger, consolidation, business combination, purchase or disposition of any amount of the assets or capital stock of or other equity interest in Channelhealth or the Enterprise Solutions Division or Systems Division of IDX as currently conducted, which we refer to as a "Channelhealth acquisition transaction"; . facilitate, encourage, solicit or initiate discussions, negotiations or submissions of proposals or offers in respect of a Channelhealth acquisition transaction; . furnish to any person any information concerning Channelhealth or IDX in connection with any Channelhealth acquisition transaction; or . otherwise cooperate in any way, or assist or participate in, or encourage, any effort or attempt by any person to do or seek to do any of the foregoing.

In addition, for six years from the effective time of the mergers, New Allscripts agreed to maintain in effect Channelhealth's current directors' and officers' liability insurance covering those persons who are currently covered by Channelhealth's directors' and officers' liability insurance policy, provided that in no event is New Allscripts required to expend for any one year an amount in excess of 200% of the annual premiums currently paid by Channelhealth for this insurance.

The Allscripts Voting Agreements In connection with the execution and delivery of the merger agreement, Channelhealth entered into a voting agreement with Morgan Stanley Venture Partners III, L.P., Morgan Stanley Venture Investors III, L.P. and The Morgan Stanley Venture Partners Entrepreneur Fund, L.P. and a voting agreement with Liberty Partners Holdings 6, L.L.C. under which these stockholders agreed to vote their shares of Allscripts capital stock in favor of the approval and adoption of the merger agreement and approval of the merger, and each of these stockholders also granted an irrevocable proxy to Channelhealth to vote their shares accordingly. As of the record date for the special meeting, these stockholders owned shares of Allscripts common stock representing approximately [ ]% of the total voting power of the outstanding Allscripts capital stock. The Allscripts voting agreements terminate upon the first to occur of the completion of the mergers and the termination of the merger agreement in accordance with its terms. The Channelhealth Voting Agreements In connection with the execution and delivery of the merger agreement, Allscripts entered into a voting agreement with IDX and a voting agreement with Pequot Private Equity Fund II, L.P. under which these stockholders agreed to vote their shares of Channelhealth capital stock in favor of approval and adoption of the merger agreement and approval of the mergers and each of these stockholders also granted an irrevocable proxy to Allscripts to vote their shares accordingly. As of the record date for the special meeting, IDX owned Channelhealth common shares representing approximately 97.9% of the total number of outstanding shares of Channelhealth common stock and Pequot owned Channelhealth preferred shares representing approximately 93.5% of the total number of outstanding shares of Channelhealth preferred stock. The Channelhealth voting agreements prohibit these stockholders from selling, assigning, pledging, transferring or otherwise disposing of any their Channelhealth shares prior to the Channelhealth stockholders meeting. The Channelhealth voting agreements terminate upon the first to occur of the completion of the mergers and the termination of the merger agreement in accordance with its terms. Because IDX, which owns more than a majority of the outstanding shares of Channelhealth common stock, and Pequot, which owns more than two-thirds of the outstanding shares of Channelhealth preferred stock, have each agreed to vote their shares of Channelhealth stock in favor of the merger, the Channelhealth merger proposal is expected to be approved. The Stock Rights and Restrictions Agreement Upon completion of the mergers, IDX and New Allscripts will execute the stock rights and restrictions agreement, substantially in the form of Exhibit E to the merger agreement. This summary of the stock rights and restrictions agreement is qualified in its entirety by reference to the form of stock rights and restrictions agreement, which is incorporated by reference into this proxy statement/prospectus. New Allscripts Board of Directors From and after the date of the stock rights and restrictions agreement until the earlier of (1) termination of the agreement or (2) the date that IDX and its affiliates beneficially own fewer than 25% of the New Allscripts 69

common shares issued to IDX upon completion of the Channelhealth merger, IDX will be entitled to designate an individual to the New Allscripts board of directors. The initial IDX designee to the New Allscripts board will be Richard E. Tarrant, the Chief Executive Officer of IDX and the Chairman of the Board, Chief Executive Officer and President of Channelhealth. In addition, so long as (1) the IDX designee is Mr. Tarrant and (2) IDX and its affiliates beneficially own greater than 75% of the New Allscripts common shares issued to IDX upon completion of the Channelhealth merger, Mr. Tarrant will be the sole non- executive Vice Chairman of the New Allscripts board. IDX will commit to make Mr. Tarrant reasonably available for initial "road show" efforts undertaken by Allscripts in connection with the merger agreement and for subsequent meetings with customers of the Channelhealth business, which will occur at least once a month. Limitation on Business Combination Transactions During the term of the stock rights and restrictions agreement, each of IDX and New Allscripts agrees not to engage in or propose any transaction referred to in the agreement as a "business combination," which means a merger, consolidation, "business combination" as defined in Section 203 of the Delaware General Corporation Law as currently in effect, compulsory share exchange or other transaction involving the other and pursuant to which the other party's voting securities are exchanged for cash, securities or other property, or any sale of all or substantially all of the assets or liquidation of the other party, including by means of a tender or exchange offer, or request or solicit any other person to engage in or propose a business combination, unless the transaction is approved by a majority of the other party's continuing directors or the party engaging in or proposing the transaction beneficially owns less than 5% of the other party's voting securities and has no representative on the other party's board of directors. IDX and New Allscripts also agreed that for the term of the stock rights and restrictions agreement, the operative provisions, as presently in effect, of Section 203 of the Delaware General Corporation Law will apply to any business combination between the parties notwithstanding that those provisions might otherwise apply for a shorter period of time. "Continuing director" of a party as used in the stock rights and restrictions agreement means any member of that party's board who was a member of the board at the date the agreement is signed or who is recommended or elected to the board by a majority of the continuing directors to fill a vacancy arising as a result of an increase in the number of directors after that date, and any successor of a continuing director, who was recommended or elected to succeed a continuing director by a majority of the continuing directors. Limitation on Acquisition of Additional Voting Securities Without the consent of a majority of the other party's continuing directors, neither party may acquire any additional voting securities of the other. Notwithstanding the foregoing, in the event IDX sells any of its shares of New Allscripts common stock, it may acquire additional shares without having to obtain New Allscripts' consent up to an aggregate amount that would cause IDX to hold the same number of shares of New Allscripts common stock that it held at the date the agreement is signed, provided that IDX cannot acquire additional shares until six months have lapsed from the date of any sale of shares by IDX and if IDX acquires additional shares pursuant to this clause of the agreement, it cannot sell any New Allscripts shares until 30 days have lapsed from the date of acquisition. Restrictions on Transfer by IDX During the term of the stock rights and restrictions agreement, without the prior written consent of a majority of the New Allscripts continuing directors, IDX agrees not to transfer beneficial ownership of any of its New Allscripts voting securities except as follows: . to affiliates of IDX that agree to be bound by the same restrictions applicable to IDX under the stock rights and restrictions agreement; . to New Allscripts or a subsidiary of New Allscripts; 70

. pursuant to a merger, consolidation or compulsory share exchange to which New Allscripts is a party; . as a pro rata dividend or distribution to holders of IDX common stock; provided that if such a dividend or distribution is made to a non-public stockholder of IDX, such holder must agree to the restrictions provided under the stock rights and restriction agreement; . pursuant to a tender or exchange offer commenced by any person other than IDX or any of its affiliates, if at the time of public announcement of the tender or exchange offer (1) IDX and its affiliates beneficially own collectively fewer than 5% of the then outstanding voting securities of New Allscripts and no representative of IDX in serving on the New Allscripts board or (2) IDX and its affiliates beneficially own collectively greater than 5% of the then outstanding voting securities of New Allscripts and a majority of the New Allscripts continuing directors recommends acceptance of the offer to New Allscripts stockholders; . from and after the first anniversary of the date of the stock rights and restrictions agreement, pursuant to a private placement, or pursuant to Rule 144 as described below, provided that in any year, IDX cannot transfer more than 25% of the number of New Allscripts common shares held by IDX at the date of the agreement, plus any additional New Allscripts voting securities that IDX or its affiliates may from time to time own after that date, and during any particular year IDX cannot transfer more than 16.6667% of those shares in any month in that year and provided further than IDX is not permitted to cumulate, or carry forward for transfer in subsequent periods either (1) unsold maximum monthly eligible transfer amounts from month to month during any particular year or (2) unsold maximum annual eligible transfer amounts from year to year; and . pursuant to Rule 144 under the Securities Act, subject to the volume limitations set forth in the bullet point above, provided that no transfers are permitted pursuant to Rule 144 except through a market maker in New Allscripts common stock approved in advance by New Allscripts, or as otherwise previously approved by New Allscripts. Additionally, during each of the periods from and after the first anniversary of the date of the stock rights and restrictions agreement through the second anniversary of that date and from and after the third anniversary through the fourth anniversary of that date, IDX has the right to notify New Allscripts that IDX wants to transfer in a single transaction either 50% or 100% of the maximum number of New Allscripts shares that it would be permitted to transfer in that period, and the price at which IDX would be willing to transfer those shares. Upon receipt of that notice, New Allscripts will have a period of 10 days within which to arrange for the purchase of the offered shares by a purchaser selected by New Allscripts in its sole discretion for cash at a price per share equal to the average of the last sale price for New Allscripts common stock for the five trading days immediately preceding the date that New Allscripts notifies IDX that New Allscripts has arranged for the purchase of the IDX shares, provided that IDX has no obligation to transfer any of the shares to the proposed purchaser if the purchase price does not equal at least 90% of the price named by IDX in its notice to New Allscripts of IDX's desire to transfer shares. If New Allscripts does not arrange for a purchase of the IDX shares covered by a notice delivered by IDX under this clause of the agreement, IDX is free to transfer those shares, but subject to and in accordance with the time, volume and other restrictions set forth above. After the fifth anniversary of the date of the stock rights and restrictions agreement, if IDX wants to transfer a number of New Allscripts common shares in excess of 2.5% of the then issued and outstanding shares of New Allscripts common stock, IDX must first notify New Allscripts and set forth in the notice the number of shares or a minimum and maximum number of shares that IDX wants to transfer, and the price at which IDX would be willing to transfer those shares. New Allscripts will have a period of 10 days within which to arrange for purchase of the offered shares by a purchaser selected by New Allscripts in its sole discretion for cash at a price equal to the average of the last sales price for New Allscripts common stock for the five trading days immediately preceding the date that New Allscripts notifies IDX that New Allscripts has arranged for the purchase of the IDX shares, provided that IDX has no obligation to transfer any of the shares to the proposed purchaser if the purchase price does not equal at least 90% of the price named by IDX in its notice to New Allscripts of IDX's desire to transfer shares. 71

The stock rights and restrictions agreement also provides that if during the period from the third anniversary through the fourth anniversary of the agreement, New Allscripts proposes to file a registration statement under the Securities Act with respect to a primary firm commitment underwritten public offering of New Allscripts common stock, IDX will have the right to "piggyback" on the offering by notifying New Allscripts that IDX wants to include some or all of its New Allscripts shares in the registration, subject to customary "cutback" provisions. New Allscripts will pay all of the expenses of the piggyback registration, except underwriting discounts and commissions on shares sold by IDX, fees of IDX's counsel and any transfer taxes applicable to the sale of the IDX shares. Additionally, New Allscripts agreed to enter into customary underwriting arrangements and to indemnify IDX against Securities Act liabilities arising from the offering to the extent customarily undertaken by issuers in connection with piggyback registrations. In addition, Richard E. Tarrant, Chief Executive Officer of each of IDX and Channelhealth, and who will be appointed to the New Allscripts board as its sole non-executive Vice Chairman upon completion of the mergers, signed the stock rights and restrictions in his individual capacity for the purpose of agreeing that for the six-month period following completion of the merger, he will not transfer any of the New Allscripts common shares he receives in the Channelhealth merger unless prior to the expiration of that period Glen E. Tullman, Chairman and Chief Executive Officer of New Allscripts, transfers for his own account any New Allscripts common shares. "Transfer" as used in the stock rights and restrictions agreement means any sale, transfer, writing of options or other conveyance of beneficial ownership in the securities to which the term relates. Voting of New Allscripts Shares Held by IDX Generally the stock rights and restrictions agreement permits IDX to vote in its complete discretion on all matters voted on by New Allscripts stockholders. Notwithstanding the foregoing, unless both of the conditions described below are met, IDX must vote all of its New Allscripts shares in accordance with the recommendation of the New Allscripts continuing directors on any matter that: . constitutes a business combination; . involves the acquisition by any person other than IDX or its affiliates of beneficial ownership of greater than 50% of the then outstanding New Allscripts voting securities; . involves the issuance by New Allscripts of its own securities for cash; or . involves any acquisition by New Allscripts, whether through merger, share exchange, purchase of assets or otherwise; provided that, if both of the following conditions are met, IDX may vote its New Allscripts shares on the matters listed above in IDX's complete discretion: . the average of the last sale price of New Allscripts common stock for the 90 trading days immediately preceding the date in which the matter is voted upon is less than $14.5625 per share, which equals 50% of the last sale price of New Allscripts common stock on July 12, 2000, the last trading day before announcement of the transaction; and . there exists no continuing and uncured default by IDX under the merger agreement, the stock rights and restrictions agreement, the strategic alliance agreement or the cross-licensing agreement that shall have resulted in a material adverse effect on the business, properties, results of operation, prospects, conditions (financial or otherwise) or per share market value of New Allscripts common stock. IDX's Right to Participate in Securities Issuances by New Allscripts If at any time during the term of the stock rights and restrictions agreement New Allscripts plans to issue New Allscripts voting securities, or securities exercisable, exchangeable for or convertible into New Allscripts voting securities and as a result, IDX's beneficial ownership of all outstanding New Allscripts voting securities 72

would be reduced to below 2% after giving effect to the proposed transaction, then New Allscripts must offer to sell to IDX a number or amount of the securities proposed to be issued that, if purchased by IDX, would permit IDX and its affiliates to beneficially own a number of New Allscripts voting securities determined by dividing the aggregate number of outstanding New Allscripts common shares then beneficially owned by IDX by the total number of New Allscripts common shares then outstanding. Termination The stock rights and restrictions agreement will terminate by its terms on its tenth anniversary, but it may be terminated earlier as follows: . by mutual written consent of IDX and New Allscripts; or . by IDX if New Allscripts files for bankruptcy, or another person commences a bankruptcy proceeding against New Allscripts and the proceeding is not dismissed or stayed within 60 days, or if an order for relief under a bankruptcy law is entered against New Allscripts. The Strategic Alliance Agreement Upon completion of the mergers, IDX and New Allscripts will execute the strategic alliance agreement, substantially in the form of Exhibit D to the merger agreement. This summary of the strategic alliance agreement is qualified in its entirety by reference to the form of strategic alliance agreement, which is incorporated by reference into this proxy statement/prospectus. Marketing of Channelhealth Products The strategic alliance agreement provides for a ten-year strategic alliance under which the parties will cooperate to develop and market Channelhealth products pursuant to a development plan to be updated at least quarterly during the term of the alliance. Each of New Allscripts and IDX will be required to develop connectivity between their respective products to facilitate data exchange and ease of use. Each party will develop and maintain interfaces with respect to identified products of the other party and will reasonably maintain compatibility of their respective products with any updates to the other party's products. Under the alliance, the parties will mutually develop and regularly update a plan for marketing New Allscripts products to IDX customers and prospects. The marketing plan will describe detailed activities, responsibilities and sales forecasts over two-year periods during the term of the alliance. The parties will cooperate to publicize the alliance, will jointly develop and produce product marketing materials and will feature each other at trade shows and user group meetings. The parties will be required to compensate and incent their sales forces to sell New Allscripts' products to IDX customers and prospects. Marketing Restrictions on New Allscripts During the term of the alliance, New Allscripts will be prohibited from developing, or cooperating with specified direct competitors of IDX to develop or provide, practice management products other than those currently marketed by Allscripts. New Allscripts will also be prohibited from marketing, selling, licensing, cooperatively marketing or otherwise distributing any products competitive with the "virtual office" component of IDX's "Patient Channel" product. Notwithstanding the foregoing, New Allscripts may cooperatively market its products to non-IDX customers with any vendor of practice management products that is not one of the specified direct competitors of IDX. New Allscripts may also cooperate with any vendor of practice management products on a case-by-case basis in the deployment of such vendor's practice management products, provided that any interface and data exchange development services performed by New Allscripts in that connection are provided at a charge that is consistent with the ordinary and customary practice of New Allscripts. New Allscripts may market its products directly to IDX customers. 73

Marketing Restrictions on IDX During the term of the alliance, IDX will be prohibited from cooperating with direct competitors of New Allscripts to develop or provide any products similar to or in competition with New Allscripts' products other than such products currently marketed by IDX. Notwithstanding the foregoing, IDX may provide products and services similar to New Allscripts' products as an offering integrated with IDX's "LastWord," "IDXrad," "Imaging Suite" and other non-practice management products and may cooperate with others who provide products similar to New Allscripts' products on a case-by-case basis in the deployment of such products, provided that any interface and data exchange development services performed by IDX in that connection are provided at a charge that is consistent with the ordinary and customary practices of IDX. In connection with its "EDiX" product, IDX is restricted from providing hand-held devices (except for dictation), but this restriction terminates if IDX ceases to control EDiX Corporation. Except with respect to its "LastWord" product, IDX may establish direct connections only for pharmaceutical benefit managers, drug manufacturers and drug distributors involving a direct message to a patient via IDX's "Patient Channel" product. IDX may market and re-sell the "Clinical Management Suite" product, although New Allscripts is entitled to a share of the revenues generated from sales of this product. Termination of Marketing Restrictions Either party may terminate the marketing restrictions to which it is subject upon the occurrence of a material adverse change in the business, properties, results of operations or condition (financial or otherwise) of the other party (other than changes that are the result of economic factors affecting the economy as a whole or changes that are the result of factors generally affecting the specific industry or markets in which the party competes). The determination of whether a change is a material adverse change giving rise to a termination right is subject to arbitration. Compensation New Allscripts and IDX will be entitled to agreed upon revenue sharing for sales of each other's products. Under the strategic alliance agreement, IDX will guarantee gross revenues to New Allscripts of $6,667 per day from sales of Allscripts products from the date of completion of the mergers until December 31, 2000. IDX will guarantee gross revenues from those sales of $4.5 million in 2001. New Allscripts Change of Control If during the term of the alliance, a change of control occurs with respect to New Allscripts whereby a direct competitor of IDX will control New Allscripts, IDX will, for the remainder of the term of the alliance, receive a revenue share on sales of all New Allscripts products (other than pharmaceutical products) equal to the percentage of revenue share to which IDX was entitled on such products at the time of the change of control and, at the end of the term of the alliance, IDX will receive the source code for all Allscripts products. IDX Change of Control If during the term of the alliance, a change of control occurs with respect to IDX whereby a direct competitor of New Allscripts will control IDX, New Allscripts will, for the remainder of the term of the alliance, receive a revenue share on sales of all IDX "Patient Channel" products equal to the percentage of revenue share to which New Allscripts was entitled at the time of the change of control and, at the end of the term of the alliance, New Allscripts will receive the source code for all IDX "Patient Channel" products. Termination of Alliance Either of New Allscripts or IDX may terminate the alliance in the event such party becomes insolvent or if the other party has defaulted under or breached any material term of the strategic alliance agreement and has not cured such default or breach within 120 days after it occurs. 74

The Amended and Restated Cross License and Software Maintenance Agreement Upon completion of the mergers, IDX and Channelhealth will execute the amended and restated cross license and software maintenance agreement, substantially in the form of Exhibit F to the merger agreement. This summary of the amended and restated cross license and software maintenance agreement is qualified in its entirety by reference to the form of amended and restated cross license and software maintenance agreement, which is incorporated by reference into this proxy statement/prospectus. Cross License The amended and restated cross license and software maintenance agreement provides for, in the case of IDX, the granting of a perpetual, non-exclusive, non-cancelable and non-terminable, fully paid-up license to Channelhealth permitting Channelhealth to copy, use, display, perform, adopt, modify and maintain certain IDX software applications and related intellectual property rights, and create derivative works with regard to the software, for the purpose of merging IDX software with New Allscripts' products and to market and sublicense IDX software in connection with the marketing of those products and, in the case of Channelhealth, the granting of a perpetual, non-exclusive, non- cancelable and non-terminable, fully paid-up license to IDX permitting IDX to copy, use, display, perform, market, sublicense, transmit, create and own derivative works and to distribute certain Channelhealth software applications and related intellectual property rights in connection with IDX's "Patient Channel" business. Support Under the amended and restated cross license and software maintenance agreement, each of IDX and Channelhealth will agree to provide the other with software maintenance and updates during the term of the strategic alliance between IDX and New Allscripts. IDX and Channelhealth will also provide customer specific implementation services and consulting services at the same service level and compensation rates as provided to their own customers. Termination The amended and restated cross license and software maintenance agreement is subject in part to the terms of the strategic alliance entered into between New Allscripts and IDX. In the event that the strategic alliance agreement is terminated or not renewed, the license granted by IDX to Channelhealth will terminate with respect to certain IDX technologies developed by IDX and incorporated by IDX into IDX software, except as used by Channelhealth to create or maintain compatibility or connectivity between New Allscripts products and IDX products. 75

BUSINESS OF CHANNELHEALTH Channelhealth sells physician-focused, Internet-based software applications and services that automate many of the clinical and administrative functions involved in the healthcare delivery process. Channelhealth's solution is designed to help healthcare providers lower healthcare costs and improve decision making by managing information flows in an efficient and timely manner. Channelhealth's suite of applications, which are known collectively as the "Physician Channel," consists of: Application Key Applications and Services - ------------------------------------------------------------------------------------------ Physician Access to practice management and clinical functions (schedules, tasks, Homebase patient lists, e-mail), personally configured links to clinically relevant content and continuing medical education and non-clinical content - ------------------------------------------------------------------------------------------ WebWorks Office automation and work-flow integration tools that create task lists for the physicians and their support teams - ------------------------------------------------------------------------------------------ ChargeWorks Automated encounter form that includes regulatory compliance decision support - ------------------------------------------------------------------------------------------ DocWorks Electronic dictation and transcription services with on-line tracking, viewing and printing capabilities - ------------------------------------------------------------------------------------------ MedWorks Medication management and prescription communication for ambulatory patients with drug utilization review and plan-specific formulary checking - ------------------------------------------------------------------------------------------ ResultWorks Display of clinical results and text documents - ------------------------------------------------------------------------------------------ OrderWorks Ordering of diagnostic tests, supplies and other items for ambulatory patients - ------------------------------------------------------------------------------------------ NoteWorks Structured clinical note creation and editing Channelhealth delivers its Physician Channel services through an application services provider model and integrates them with a provider organization's existing practice management system and databases. Channelhealth has designed its services to be implemented on a modular basis. Thus, the Physician Channel services can be implemented incrementally with minimal disruption and up-front investment. Channelhealth has entered into strategic agreements with various providers of on-line medical resources to better service the healthcare providers using the Physician Channel. These agreements provide users of the Physician Channel with access to continuing medical information courses, clinical reference and health awareness information, as well as access to prescription benefit management rules and eligibility, pertinent patient medication history and network pharmacy listings. Channelhealth has also entered into an administrative services agreement, a marketing, development and service agreement and a cross license and software maintenance agreement with IDX. Upon the closing of the mergers, the marketing, development and service agreement and the cross license and software maintenance agreement will terminate and be replaced with the strategic alliance agreement and the amended and restated cross license and software maintenance agreement. The administrative services agreement will terminate as of December 31, 2000. See "The Related Transaction Agreements" on page 69. Channelhealth's target customers are large healthcare provider organizations, primarily consisting of large physician group practices, hospitals and integrated delivery networks. Channelhealth competes for customers with other providers of Internet-based healthcare solutions and clinical systems for the key service offerings of connectivity, content, applications and the browser-based desktop and personal digital assistant user interface. While it enjoys the advantage of access to a large installed base of provider organizations in the United States and strong relationships with executive management at prestigious healthcare organizations nationwide, Channelhealth expects competitors to aggressively target that customer base. Channelhealth distributes its services to clients under license agreements that typically grant customers nonexclusive, nontransferable licenses to use the software and services. To provide complete services for its clients, Channelhealth provides technical service and support to its customers 24 hours a day and seven days a week. 76

As of July 31, 2000, Channelhealth employed a total of 91 full time employees for its "Physician Channel" business at its corporate headquarters in Burlington, Vermont and regional office in Boston, Massachusetts. None of its employees is represented by a labor union. Channelhealth's principal executive and corporate offices, development, and customer support operations are located in Burlington, Vermont and Boston, Massachusetts. Channelhealth leases both facilities from IDX. 77

CHANNELHEALTH MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS General The Physician Channel business of Channelhealth reported a net loss of $6,276,000 for the six months ended June 30, 2000. Excluding a compensation charge related to the issuance of stock options of $269,000, the net loss amounted to $6,007,000, as compared to a net loss of $3,089,000 for the same period of 1999. The Physician Channel business reported a net loss of $9,649,000, $3,616,000 and $2,771,000 for the years ended December 31, 1999, 1998 and 1997, respectively. For comparison purposes the net loss for 1999 after excluding a compensation charge of $4,561,000 related to the issuance of vested stock options to employees of the parent company of Channelhealth in the fourth quarter of 1999 amounted to $5,088,000. Results of Operations Six Months Ended June 30, 2000 Compared to Six Months Ended June 30, 1999 Revenue. The Physician Channel business' total revenue increased to $815,000 for the six months ended June 30, 2000 from $690,000 for the same period in 1999, an increase of $125,000, or 18.1%. Revenue from system sales decreased from $305,000 for the six months ended June 30, 1999 to $42,000 for the six months ended June 30, 2000, a decrease of $263,000, or 86.2%. The decrease in sales was due to certain of the Physician Channel business' customers delaying purchasing decisions with respect to certain Physician Channel business software systems. Management believes such delays are due to a number of factors, including the announced migration of the Physician Channel business' software systems to Internet-based applications and services, customer organizational changes, government applied pressures on customers to reduce expenses, product complexity, and customer preoccupation with internal Year 2000 issues. Maintenance and service revenue increased to $773,000 during the six months ended June 30, 2000 (94.8% of total revenue) compared to $385,000 (55.8% of total revenue) in the corresponding period in 1999, an increase of $388,000, or 100.8%. The increase was primarily due to an increase in maintenance and service revenue from new customers obtained in 1999 and the decision by customers to continue to support historical software systems rather than purchase new ones for the reasons noted above. Cost of Revenues. The cost of revenues decreased to $941,000 for the six months ended June 30, 2000 from $1,199,000 for the same period in 1999, a decrease of $258,000 or 21.5%. The cost of revenues decreased between the periods primarily due to a reduction in amortization expense of capitalized software for the period ended June 30, 2000. The gross profit margin increased from -73.8% for the six months ended June 30, 1999 to -15.5% for the same period in 2000. The improvement in gross profit margin was due to both the reduction in amortization expense and the more efficient utilization of installation and support services personnel in performing revenue generating customer maintenance and support. The overall negative gross margins during both periods are primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development, particularly with its Internet-based applications and services. Selling, General and Administrative Expenses. Selling, general and administrative expenses increased to $1,685,000 for the six months ended June 30, 2000 from $837,000 for the same period in 1999, an increase of $848,000 or 101.3%. As a percentage of total revenue, selling, general and administrative expenses increased to 206.7% for the six months ended June 30, 2000 from 121.3% for the same period in 1999. The increase in selling, general and administrative expenses is due to incremental expenses, primarily additional personnel and marketing expenses, incurred to sell, market and administrate the Physician Channel business' new business initiatives in the Internet-based software applications and services markets. The overall high percentage of selling, general and administrative expenses to revenue during both periods is primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development, particularly with its Internet-based applications and services. 79

Research and Development. Research and development expenses increased to $2,539,000 for the six months ended June 30, 2000 from $1,282,000 for the same period in 1999, an increase of $1,257,000, or 98.0%. As a percentage of total revenues, research and development expenses increased to 311.5% for the six months ended June 30, 2000 from 185.8% for the same period in 1999. The increase in research and development expenses was primarily due to additional personnel and efforts utilized to develop the Physician Channel business' new Internet-based applications and services. The overall high percentage of research and development expenses to revenue during both periods is primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development, particularly with its Internet-based software applications and services. Compensation Charge Related to Issuance of Stock Options. In the first quarter of 2000, Channelhealth issued immediately vested options to certain employees of the parent company. Accordingly, the Physician Channel business has recognized compensation expense of approximately $269,000 related to the issuance of the vested stock options, based on the fair market value of the options on the date of issuance. Settlement of Litigation. In connection with the settlement of litigation arising from a contractual dispute with respect to an exclusivity provision from a supply contract, Channelhealth has incurred settlement and legal costs as of June 30, 2000 of $936,736. Accordingly, the costs have been recognized in the statement of operations for the six month period ended June 30, 2000. Interest Expense. Interest expense has increased to $720,000 for the six months ended June 30, 2000 from $460,000 for the same period in 1999, an increase of $260,000 or 56.5%. The increase in interest expense is a result of the increase of IDX's investment in the Physician Channel business. Year Ended December 31, 1999 Compared to Year Ended December 31, 1998 Revenue. The Physician Channel business' total revenue increased to $2,369,000 for the year ended December 31, 1999 from $1,113,000 for the year ended December 31, 1998, an increase of $1,256,000, or 112.8%. Revenue from system sales increased from $671,000 for the year ended December 31, 1998 to $1,050,000 in system sales revenue for the year ended December 31, 1999, an increase of $379,000, or 56.4%. The increase in sales was primarily due to the sale of clinical software systems to several new customers in 1999. Maintenance and service revenue increased to $1,319,000 during the year ended December 31, 1999 (55.7% of total revenue) compared to $441,000 (39.6% of total revenue) in 1998, an increase of $878,000, or 199.1%. The increase was primarily due to an increase in maintenance and service revenue from new contracts obtained in 1998 and 1999, and 1999 service revenues related to supporting Year 2000 issues. Cost of Revenues. The cost of revenues decreased slightly to $2,461,000 for the year ended December 31, 1999 from $2,579,000 in 1998, a decrease of $118,000, or 4.6%. The cost of revenues decreased due to the consistent level of personnel utilized in client services to support incremental system sales revenue and maintenance and service revenue. The gross profit margin increased from -131.7% for the year ended December 31, 1998 to -3.9% for the same period in 1999. The improvement in gross profit margin was primarily due to an increase in revenue, including the $379,000 increase in system sales with higher gross margins than maintenance and service revenue, combined with the more efficient utilization of installation and support personnel in 1999. The negative gross margins during both years are primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development. Selling, General and Administrative Expenses. Selling, general and administrative expenses increased to $1,551,000 for the year ended December 31, 1999 from $804,000 in 1998, an increase of $747,000, or 92.9%. As a percentage of total revenue, selling, general and administrative expenses decreased to 65.5% in 1999 from 72.2% in 1998. The increase in selling, general and administrative expenses is due to incremental expenses, primarily additional personnel and marketing expenses, incurred to sell and market the Physician Channel 80

business' software systems and support services. As a percentage of revenue, the expenses decreased due to the increase in revenue combined with a relative high fixed cost component of the expenses. The overall high percentage of selling, general and administrative expenses to revenue during both years is primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development. Research and Development. Research and development expenses increased to $2,407,000 for the year ended December 31, 1999 from $710,000 in 1998, an increase of $1,697,000, or 239%. As a percentage of total revenues, research and development expenses increased to 101.6% for the year ended December 31, 1999 from 63.8% for the same period in 1998. The increase in research and development expenses in dollars and as a percentage of revenue was primarily due to significant additional personnel and activities initiated in 1999 to begin development of the Physician Channel business' new Internet-based software applications and services. The overall high percentage of research and development expenses to revenue during both years is primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development. Compensation Charge Related to Issuance of Stock Options. In the fourth quarter of 1999, Channelhealth issued immediately vested options to certain employees of the parent company. Accordingly, the Physician Channel business has recognized compensation expense of approximately $4,561,000 related to the issuance of the vested stock options based on the fair market of the options on the date of issuance. Interest Expense. Interest expense has increased to $1,038,000 for the year ended December 31, 1999 from $636,000 for the same period in 1998, an increase of $402,000 or 63.2%. The increase in interest expense is a result of the increase of IDX's investment in the Physician Channel business. Year Ended December 31, 1998 Compared to Year Ended December 31, 1997 Revenue. The Physician Channel business' total revenue decreased to $1,113,000 for the year ended December 31, 1998 from $1,473,000 in 1997, a decrease of $360,000, or 24.4%. Revenue from system sales decreased from $933,000 for the year ended December 31, 1997 to $671,000 in system sales revenue in 1998, a decrease of $262,000, or 28.1%. The disappointing decrease in sales was due to fewer than anticipated software system sales in 1998. Maintenance and service revenue also decreased to $441,000 during the year ended December 31, 1998 (39.6% of total revenue) compared to $540,000 (36.7% of total revenue) in 1997, a decrease of $99,000, or 18.3%. The decrease was primarily due to a decrease in maintenance and service revenue resulting from the decrease in system sales and fewer contracts for support services in 1998. Cost of Revenues. The cost of revenues increased to $2,579,000 for the year ended December 31, 1998 from $1,931,000 in 1997, an increase of $648,000, or 33.6%. The cost of revenues increased between the periods due to the addition of installation and support personnel in anticipation of increased sales in 1998 and an increase in amortization expense of capitalized software. The gross profit margin decreased from -31.1% for the year ended December 31, 1997 to - 131.7% in 1998. The decrease in gross profit margin was primarily due to significantly lower revenue combined with the incremental expenses of additional personnel and amortization of capitalized software. The overall negative gross margins during both years are primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development. Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased to $804,000 for the year ended December 31, 1998 from $984,000 in 1997, a decrease of $180,000, or 18.3%. As a percentage of total revenue, selling, general and administrative expenses increased to 72.2% for the year ended December 31, 1998 from 66.8% in 1997. The decrease in selling, general and administrative expenses is due primarily to lower sales commission expenses resulting from the significant decrease in revenue from 1997 to 1998. The overall high percentage of selling, general and administrative expenses to revenue during both years is primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development. 81

Research and Development. Research and development expenses decreased to $710,000 for the year ended December 31, 1998 from $947,000 in 1997, a decrease of $237,000, or 25.0%. As a percentage of total revenues, research and development expenses decreased to 63.8% for the year ended December 31, 1998 from 64.3% in 1997. Research and development expenses decreased between 1997 and 1998 due to a decrease in new development activities and the corresponding reduction in personnel. The overall high percentage of research and development expenses to revenue during both years is primarily due to the high fixed costs relative to sales volume resulting from the early stage nature of the Physician Channel business' development. Interest Expense. Interest expense has increased to $636,000 for the year ended December 31, 1998 from $382,000 for the same period in 1997, an increase of $254,000 or 66.5%. The increase in interest expense is a result of the increase of IDX's investment in the Physician Channel business. Liquidity and Capital Resources The Physician Channel business has funded its operations, working capital needs and capital expenditures primarily through net proceeds from its parent company, IDX Systems Corporation, of which approximately $32 million is attributable to venture capital financing secured by Channelhealth. Cash flows related to operating activities are comprised principally of net loss and depreciation and are also affected by the changes in accounts receivable and deferred revenue. Due to the nature of the Physician Channel business, accounts receivable and deferred revenue fluctuate considerably. This is due to, among other things, the length of the sales cycle and installation efforts that are dependent upon the size of the transaction, the changing business plans of the customer, the effectiveness of the customers' management and general economic conditions. Cash flows related to investing activities have principally been related to the purchase of computers and office equipment. Computer and equipment purchases have been financed through net proceeds from the parent company. Cash flows from financing activities have principally been related to net proceeds from the parent company, of which approximately $32 million is attributable to venture capital financing secured by Channelhealth. In the first quarter of 2000, Channelhealth issued preferred stock to Pequot Private Equity Fund II, L.P. for approximately $30 million, representing an equity interest in Channelhealth of approximately 9%. In the same round of financing, Channelhealth also raised approximately $2 million additional from various other minority stockholders, representing an equity interest in Channelhealth of less than 1%. The proceeds from the issuance of this preferred stock combined with other funds from the parent has been the source of the net proceeds provided to the Physician Channel business of Channelhealth. Channelhealth is currently leasing its facilities in South Burlington, Vermont from its parent company. Management believes that current operating funds and capital available from its current parent company would be sufficient to meet its operating requirements at least through the next twelve months. Upon completion of the proposed transaction, capital will not be available to Channelhealth from its current parent company. On September 29, 2000, Channelhealth entered into a 3-year lease with a leasing company for computer equipment. This lease will allow Channelhealth to establish its data center and continue its planned expansion as an ASP provider. Total lease payments for this equipment will be approximately $806,000. In October 2000, Healtheon/WebMD, a provider of content and transaction processing for Channelhealth's Internet services under an agreement dated June 8, 2000, indicated to Channelhealth that it would seek to terminate the June 8, 2000 agreement. As of November 3, 2000, no proposal for a renegotiated agreement, and no notice of termination or breach of the agreement, has been received from Healtheon/WebMD by Channelhealth. The effect on Channelhealth's business of Healtheon/WebMD's actions with respect to this agreement is not yet determinable but could have an adverse effect. 82

BUSINESS OF ALLSCRIPTS AND NEW ALLSCRIPTS Allscripts Allscripts provides physicians with Internet and client/server medication management solutions designed to improve the quality and cost effectiveness of pharmaceutical healthcare.

Allscripts currently offers products in four categories: point-of-care medication management, Internet products and services, including e-detailing, information products and prepackaged medications. Allscripts TouchScript software enables electronic prescribing, routing of prescription information and capturing of prescription data at the point of care.

New Allscripts New Allscripts is currently a wholly-owned subsidiary of Allscripts that has not conducted any business activities except in connection with the mergers. As a result of the mergers, Allscripts and Channelhealth will each become a wholly-owned subsidiary of New Allscripts. Accordingly, the business of New Allscripts will be the business currently conducted by Allscripts and the Physician Channel business of Channelhealth. Legal Proceedings Two complaints, styled as shareholder class action complaints, have been filed in the United States District Court for the Northern District of Illinois against Allscripts and its President and Chief Financial Officer, David B. Mullen, alleging that the defendants failed to disclose that revenue relating to Allscripts' relationship with IMS Health was not properly recorded in the second quarter of 2000. The complaints are captioned Bredeson v. Allscripts, Inc. and David B. Mullen, Civ. No. 00C-6796 (N. D. Ill., filed on October 31, 2000), and Karmazin v. Allscripts, Inc. and David B. Mullen, Civ. No. 00C-6864 (N.D. Ill., filed on November 2, 2000). The complaints in these actions purport to be brought on behalf of individuals who purchased common stock of Allscripts during the period of July 27, 2000 through and including October 26, 2000. The plaintiffs allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and seek unspecified damages. According to reports on the Internet, at least one additional similar complaint has been filed against Allscripts. At this time, management is unable to determine the likely outcome of this matter or to reasonably estimate the amount of loss with respect to this matter. 83

DESCRIPTION OF NEW ALLSCRIPTS CAPITAL STOCK The following summary of the capital stock of New Allscripts is qualified in its entirety by reference to the complete text of the Amended and Restated Certificate of Incorporation of New Allscripts, a copy of which is filed as Exhibit 3.1 to the registration statement filed by New Allscripts. Authorized Capital Stock New Allscripts Common Stock Holders of shares of New Allscripts common stock will be entitled to one vote for each share held on all matters subject to a vote of stockholders, subject to the rights of holders of any outstanding preferred stock, and will not have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors will be able to elect all of the directors standing for election, subject to the rights of holders of any outstanding preferred stock. Holders of common stock will be entitled to receive ratably any dividends that the board of directors may declare out of funds legally available therefor, subject to any preferential dividend rights of outstanding preferred stock. Upon the liquidation, dissolution or winding up of New Allscripts, the holders of common stock would be entitled to receive ratably the net assets of New Allscripts available after the payment of all debts and other liabilities and subject to the prior rights of holders of any outstanding preferred stock. Holders of common stock will have no preemptive, subscription, redemption or conversion rights. New Allscripts Preferred Stock Under its certificate of incorporation, New Allscripts will be authorized to issue 1,000,000 shares of preferred stock, which may be issued from time to time in one or more series upon authorization by the board of directors. The board of directors, without further approval of the stockholders, will be authorized to fix the number of shares constituting any series, as well as the dividend rights and terms, conversion rights and terms, voting rights and terms, redemption rights and terms, liquidation preferences and any other rights, preferences, privileges and restrictions applicable to each series of preferred stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could also adversely affect the voting power of the holders of common stock. The issuance of preferred stock could also, under some circumstances, have the effect of making it more difficult for a third party to acquire, or discouraging a third party from acquiring, a majority of New Allscripts outstanding voting stock or otherwise adversely affect the market price of New Allscripts common stock. The management of Allscripts is not aware of any plans by a third party to seek control of Allscripts or New Allscripts, and has no current plans to issue any preferred stock. New Allscripts Warrants Upon completion of the mergers, New Allscripts will assume Allscripts warrants outstanding to purchase, as of August 31, 2000, an aggregate of 27,703 shares of Allscripts common stock at an average weighted exercise price of $2.41 per share. Registration Rights of Certain Holders of New Allscripts Common Stock Liberty Partners Holdings 6, L.L.C., Morgan Stanley Venture Investors III, L.P., Morgan Stanley Venture Partners III, L.P. and The Morgan Stanley Venture Partners Entrepreneur Fund, L.P., which collectively hold 8,502,233 shares of Allscripts common stock, are entitled to registration rights with respect to these shares. Under a registration rights agreement, Morgan Stanley Venture Partners III, L.P., Morgan Stanley Venture Investors III, L.P. and The Morgan Stanley Venture Partners Entrepreneur Fund, L.P., collectively, on the one hand, and Liberty Partners Holdings 6, L.L.C., on the other hand, each are entitled to require Allscripts to register their shares of common stock three times, but not more than once in any six-month period. As of the date of filing of this proxy statement/prospectus, the Morgan Stanley parties, collectively, on the one hand, and Liberty Partners, on the other hand, have each exercised their rights to require Allscripts to register their shares 90

of Allscripts common stock one time. After completion of the merger transactions, they will be entitled to require New Allscripts to register their shares of New Allscripts common stock two times, but no more than once in any six-month period. In addition, if New Allscripts proposes or is required to register any of its common stock, either for its own account or for the account of other of its stockholders, New Allscripts will be required to notify Liberty and the Morgan Stanley partnership stockholders, and subject to the limitations specified in the registration agreement, to include in the registration all of the common stock requested to be included by those holders. New Allscripts will be obligated to bear the expenses, other than underwriting commissions, of the first registration required by Liberty or the Morgan Stanley partnerships, and of all incidental registrations. Any exercise of these registration rights may hinder New Allscripts' efforts to arrange future financings and have an adverse effect on the market price of New Allscripts' common stock. Description of Registration Rights for Earnout Shares Any shares of New Allscripts common stock issued pursuant to the earnout clause of the merger agreement will be, and the right to receive such shares is being, issued in reliance upon the exemption from the registration requirements of the Securities Act afforded by Rule 506 of the Securities and Exchange Commission's Regulation D. If any earnout shares are issued, within five business days of issuance New Allscripts will file a non-exclusive resale "shelf" registration statement to permit the unrestricted resale of those shares to the public on a continuous basis. New Allscripts will use its best efforts to cause the resale shelf registration statement to be declared effective by the Securities and Exchange Commission as soon as practicable after filing and to cause the registration statement to remain effective for a period of two years from the date of filing or such earlier time as all of the earnout shares covered by the registration statement have been sold. Certain Limited Liability, Indemnification and Anti-takeover Provisions Indemnification and Limitation of Liability New Allscripts' certificate of incorporation and by-laws provide that New Allscripts shall, with some limitations, indemnify its directors and officers against expenses, including attorneys' fees, judgments, fines and certain settlements, actually and reasonably incurred by them in connection with any suit or proceeding to which they are a party so long as they acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of New Allscripts. This indemnification also applies to a criminal action or proceeding, so long as the director or officer had no reasonable cause to believe their conduct to have been unlawful. Section 102 of the Delaware General Corporation Law permits a Delaware corporation to include in its certificate of incorporation a provision eliminating or limiting a director's liability to a corporation or its stockholders for monetary damages for breaches of fiduciary duty. However, this Section 102 provides that liability for breaches of the duty of loyalty, acts or omissions not in good faith or involving intentional misconduct, or knowing violation of the law, and the unlawful purchase or redemption of stock or payment of unlawful dividends or the receipt of improper personal benefits cannot be eliminated or limited in this manner. New Allscripts' certificate of incorporation includes a provision that eliminates, to the fullest extent permitted, director liability for monetary damages for breaches of fiduciary duty. Section 203 of the Delaware General Corporation Law Section 203 of the Delaware General Corporation Law prohibits certain transactions between a Delaware corporation and an "interested stockholder," which is defined as a person who, together with any affiliates or associates, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. This provision prohibits certain business combinations between an interested stockholder and a corporation for a period of three years after the date the interested stockholder becomes an interested stockholder, unless: . the business combination is approved by the corporation's board of directors prior to the date the interested stockholder becomes an interested stockholder; 91

. the interested stockholder acquired at least 85% of the voting stock of the corporation (other than stock held by directors who are also officers or by certain employee stock plans) in the transaction in which it becomes an interested stockholder; or . the business combination is approved by a majority of the board of directors and by the affirmative vote of 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder. For this purpose, business combinations include mergers, consolidations, sales or other dispositions of assets having an aggregate value in excess of 10% of the consolidated assets of the corporation, and certain transactions that would increase the interested stockholder's proportionate share ownership in the corporation. Upon completion of the Channelhealth merger, IDX will become an interested stockholder of New Allscripts for purposes of Section 203. Pursuant to the stock rights and restrictions agreement to be entered into between IDX and New Allscripts, IDX and Allscripts agreed that for the term of that agreement, the operative provisions, as presently in effect, of Section 203 will apply to any business combination between the parties notwithstanding that those provisions might otherwise apply for a shorter period of time. Special Meetings of Stockholders; No Stockholder Action By Written Consent New Allscripts' certificate of incorporation provides that special meetings of its stockholders may be called only by a majority of the board of directors, the Chairman or the President. In addition, the New Allscripts' certificate of incorporation provides that its stockholders may only take actions at a duly called annual or special meeting of stockholders and may not take action by written consent. Advance Notice Requirements for Stockholder Proposals and Nomination of Directors New Allscripts' by-laws provide that stockholders seeking to bring business before, or nominate directors at, any annual meeting of stockholders, must provide timely notice in writing. To be timely, a stockholder's notice must be given in writing to the Secretary of New Allscripts not fewer than 120 days prior to the meeting. The by-laws also specify requirements for a stockholder's notice to be in proper written form. Classified Board of Directors The New Allscripts certificate of incorporation and by-laws provide that the board of directors is divided into three classes of directors serving staggered three-year terms. As a result, one-third of New Allscripts' board of directors will be elected each year. See "Management of New Allscripts--Directors." Number of Directors; Removal; Vacancies The New Allscripts by-laws provide that New Allscripts will have at least three directors, with the exact number to be fixed by the board of directors. Vacancies on the board of directors may be filled only by the affirmative vote of the remaining directors then in office. The New Allscripts certificate of incorporation provides that directors may be removed only for cause and only by the holders of at least 80% of the outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. Currently the number of Allscripts directors is fixed at eight. Prior to completion of the mergers, the New Allscripts board will fix the number of New Allscripts directors at nine to accommodate the appointment to the board of Richard E. Tarrant pursuant to the stock rights and restrictions agreement. See "The Related Transaction Agreements--The Stock Rights and Restrictions Agreement--New Allscripts Board of Directors." Consideration of Constituencies with Respect to Acquisitions The New Allscripts certificate of incorporation provides that in determining whether an acquisition proposal is in the best interests of New Allscripts and its stockholders, its board of directors may, to the extent 92

permitted by law, consider all factors it deems relevant, including the effects of the acquisition upon New Allscripts' employees, suppliers and customers and the communities in which New Allscripts is located. Transfer Agent and Registrar The transfer agent and registrar for the New Allscripts common stock is LaSalle Bank N.A. 93

COMPARISON OF RIGHTS OF STOCKHOLDERS OF NEW ALLSCRIPTS AND STOCKHOLDERS OF ALLSCRIPTS New Allscripts and Allscripts are both organized under the laws of the State of Delaware. Therefore, any differences in the rights of holders of Allscripts common stock and New Allscripts common stock arise primarily from differences in their respective certificates of incorporation and by-laws. The New Allscripts certificate of incorporation and the New Allscripts by-laws are substantially similar to the Allscripts certificate of incorporation and the Allscripts by-laws, respectively. 96

COMPARISON OF CERTIFICATES OF INCORPORATION AND BY-LAWS OF NEW ALLSCRIPTS AND CHANNELHEALTH Channelhealth and New Allscripts are both organized under the laws of the state of Delaware. Therefore, any differences in the rights of holders of Channelhealth common stock or preferred stock, on the one hand, and the holders of New Allscripts common stock, on the other, arise primarily from differences in their respective certificates of incorporation and by-laws. The following is a summary of certain of the material differences between the rights of the holders of New Allscripts common stock, on the one hand, and the rights of the holders of Channelhealth common stock and the holders of Channelhealth preferred stock, on the other.

Conversion Rights New Allscripts The New Allscripts certificate of incorporation provides that the board of directors shall fix the terms, if any, upon which the shares of each series of preferred stock shall be convertible into or exchangeable for any other shares of stock of New Allscripts.

by reason of being a director or officer of Channelhealth or, at the request of Channelhealth, a director, officer or trustee of, or acting in a similar capacity with, another enterprise, against expenses (including attorneys' fees), judgments, fines and settlement amounts actually and reasonably incurred in connection with such action, suit or proceeding (but may indemnify such person only against expenses incurred in a derivative action on behalf of such corporation) or incurred by reason of being or having been a representative of Channelhealth, if such person acted in good faith and reasonably believed that his or her actions were in or not opposed to the best interests of Channelhealth and, with respect to any criminal proceeding, had no reasonable cause to believe that his or her conduct was unlawful. Channelhealth's certificate of incorporation also provides that Channelhealth may advance to any such director or officer expenses incurred in defending any action, upon receipt of an undertaking by or on behalf of the person to repay the amount advanced if it is ultimately determined that he or she is not entitled to indemnification. A determination as to the amount of the indemnification to be made by Channelhealth shall be made either (1) by a majority vote of the directors who are not parties to such action, even though less than a quorum, or, if there are no such directors or if such directors so direct, by a committee of disinterested directors designated by independent legal counsel, (2) by a majority vote of a quorum of the outstanding shares of stock of all classes entitled to vote for directors, voting as a single class, consisting of stockholders who are not parties to such action or (3) by a court of competent jurisdiction. Channelhealth's certificate of incorporation provides further that the provisions for indemnification are not exclusive of any other rights to which the person may be entitled under any law, agreement or vote of stockholders or disinterested directors.

Channelhealth The Channelhealth by-laws provide that any one or more or all of the directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors, except that the directors elected by the holders of a particular class or series of stock may be removed without cause only by vote of the holders of a majority of the outstanding shares of such class or series. Special Meetings New Allscripts The New Allscripts certificate of incorporation and by-laws provide that special meetings of stockholders may be called only by the chairman of the board, the president or by a majority of the entire New Allscripts board of directors.

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS (Information as of June 30, 2000 and for the periods ended June 30, 1999 and 2000 is unaudited) 1. Basis of Presentation The Physician Channel (PC or the Company) Business of Channelhealth Incorporated (CH), a majority owned subsidiary of IDX Systems Corporation (IDX) is engaged in developing, producing, marketing, selling and servicing modular and web-based software for physicians and their patients. The software allows physicians to access web-based content and services and includes a set of web- based software applications for the physician to manage clinical workflow. The web-based software is not expected to be available until early 2001. Prior to its availability, the Physician Channel Business' product revenue has been comprised of the license of non web-based software with many of the same functional and performance capabilities of the web-based software in development. As more fully described in Note 2, Proposed Transaction, the accompanying financial statements have been prepared in connection with the proposed sale of the PC Business to Allscripts, Inc. (Acquiror or Allscripts). The PC Business is not a separate legal entity and the financial balances associated with the PC Business are components of a larger business. Therefore, while separate financial information with respect to the PC Business assets and liabilities, revenues, costs and expenses have been presented herein, no separate asset, liability, revenue, costs and expense accounts have been specifically maintained for the PC Business in the IDX consolidated financial records. Consequently, the financial information herein has been derived from the consolidated financial records of IDX and as a result, the statements do not purport to reflect the financial position or results of operations that would have resulted if the PC Business had operated as an unaffiliated company. Certain costs and expenses incurred by IDX and CH on behalf of the PC Business have been allocated to the PC Business on various bases as discussed below that, in the opinion of management, are reasonable. These allocated costs and expenses, however, are not necessarily indicative of costs and expenses that would have been incurred had the PC Business been operating as an unaffiliated company. Revenues System sales, which include software licenses and hardware, of the PC Business were identified by specific classification codes within the CH and IDX financial accounting records representing the PC Business product lines. Revenues from services were determined from the value of maintenance contracts and specific customer projects and product installations for each customer. Cost of Revenues Costs of system sales and services were identified by specific classification codes within the CH and IDX financial accounting records representing the PC Business product lines and services. Such codes are consistent with those used to identify system sales and service revenues. Selling, General and Administrative Expenses Certain selling, general and administrative expenses, not otherwise specifically identifiable with the PC Business, are allocated on the basis of estimates of time and effort spent and number of dedicated and allocated employees. Such allocated expenses primarily include finance and accounting, human resources, information systems, selling and other administrative activities. In the opinion of management, these allocations of direct expenses were made on a reasonable basis. However, such expenses are not necessarily indicative of the level of expenses which might have been incurred had the PC Business been operating as an unaffiliated company. F-7

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) Research and Development Research and development activities related to web-based software and services are allocated on specific development projects and, if not specifically identifiable, on the basis of estimates of time and effort spent and number of dedicated and allocated employees. In the opinion of management, these allocations of direct expenses were made on a reasonable basis. However, such expenses are not necessarily indicative of the level of expenses which might have been incurred had the PC Business been operating as an unaffiliated company. Income Taxes For the purposes of these financial statements, management has applied the estimated effective income tax rate to the taxable revenues in excess of tax deductible costs and expenses as if the Physician Channel Business were an unaffiliated company for income tax reporting purposes. No benefit for available net operating loss carryforwards (NOL's) has been allocated to the PC Business because of the uncertainty that NOL's would be realizable on an unaffiliated company basis. Determination of Net Assets Assets and liabilities have been included in these statements only when they are exclusively related or attributable to the operations of the PC Business. No allocation of common assets, such as facilities, or liabilities, such as accrued officers' compensation, has been made. To the extent assets have been acquired or liabilities incurred, the PC Business has financed these activities and shown these amounts in the accompanying financial statements as net proceeds provided to the PC Business from IDX Systems Corporation. However, as discussed above, allocations of shared costs and expenses have been made in the statements of net assets of the PC Business and related statements of operations. In connection with the Proposed Transaction, the carrying value of accounts receivable, unbilled receivables and deferred revenues as of the closing date will be included in the settlement of the Merger Agreement described in Note 2. Management Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in them and the accompanying disclosures. The more significant estimates that affect these statements include allocations of costs and expenses to the PC Business and collectibillity of accounts receivable. In the opinion of management, the allocation of costs and expenses are reasonable and not materially different than if it had operated as an unaffiliated entity. However, the allocations are not necessarily indicative of costs and expenses that would have been incurred had the PC Business been operating as an unaffiliated company. Although management regularly assesses these estimates, which are based on management's knowledge of current events and actions that may be taken in the future, actual results could differ from those estimates. 2. Proposed Transaction (unaudited) On July 13, 2000, IDX announced an agreement (Merger Agreement) to sell the PC Business of CH to Allscripts, a provider of ambulatory point-of-care e- prescribing and productivity solutions for physicians. In connection with the Proposed Transaction, IDX entered into an Asset Purchase Agreement with CH whereby IDX will acquire from CH, at the closing of the Proposed Transaction, the net assets and operations of the e-Commerce Channel and certain components of the Patient Channel. Under the terms of this agreement, IDX will pay for the acquisition of these assets and operations through the cancellation of 2,771,009 shares of CH's common stock owned by IDX. In addition to the acquisition, IDX has agreed to enter into a 10-year strategic alliance whereby Allscripts will become the exclusive provider of point-of-care clinical applications sold by IDX to physician practices. F-8

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) As a result of the Asset Purchase Agreement executed as of the closing of the Proposed Transaction, the operations, assets and liabilities of CH will be comprised of the PC Business alone. Under the terms of the Proposed Transaction, which is subject to regulatory and Allscript's and CH's shareholder approval, Allscripts will exchange approximately 8.6 million shares of Allscripts common stock for all of the outstanding shares of capital stock of CH. The historical capital stock of CH as of December 31, 1999 and June 30, 2000 and on a pro forma basis as of the closing is as follows: December 31, June 30, Date of 1999 2000 Closing ------------ ----------- ----------- (unaudited) (pro forma) Series A, Convertible Preferred Stock, $0.001 par value, 3,000,000 shares authorized, none in 1999 and 2,719,429 shares issued and outstanding in 2000 and at date of closing, respectively.... -- $ 2,719 $ 2,719 Common stock, $0.001 par value, 100,000,000 shares authorized, 25,422,425, 25,527,425 and 22,756,416 shares issued and outstanding in 1999, 2000 and at date of closing, respectively............................ $25,422 25,527 22,756 Each holder of outstanding shares of Series A Preferred Stock is entitled to the number of votes equal to the number of whole shares of common stock into which the shares of Series A Preferred Stock held are then convertible. Each holder of Series A Preferred Stock is entitled to a liquidation preference in the event of a liquidation, dissolution or winding up of Channelhealth equal to the consideration paid of $11.80 per share of Series A Preferred Stock plus all dividends declared and accrued but not paid. Each share of Series A Preferred Stock is convertible at any time by the holder into one share of common stock, subject to certain anti-dilutive provisions. The Series A Preferred Stock is subject to mandatory conversion in the event of an initial public offering resulting in at least $35 million of net proceeds to Channelhealth and a market capitalization of at least $500 million. The Series A Preferred Stock is also redeemable at the option of the holder commencing on the fifth anniversary of the date of issuance. The redemption price is equal to $11.80 per share plus any declared but unpaid dividends, payable in three equal installments over three years. As described above, the pro forma information reflects the cancellation of 2,771,009 shares of CH's common stock owned by IDX as consideration for IDX's purchase of the net assets and operations of the eCommerce Channel Business and certain components of the Patient Channel Business. 3. Summary of Significant Accounting Policies Revenue Recognition In 1997, the Company recognized revenue in accordance with the provisions of Statement of Position ("SOP") No. 91-1, "Software Revenue Recognition." In October 1997 and December 1998, the American Institute of Certified Public Accountants issued SOP No. 97-2, as amended by SOP No. 98-4 and SOP 98-9, which supersedes SOP 91-1. In 1998, the PC Business adopted SOP No. 97-2, which generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on the relative fair values of those elements. The fair value of an element must be based on objective evidence that is specific to the vendor. If the vendor does not have evidence of the fair value for all the elements in a multiple-element arrangement, all revenue from the arrangement is deferred until such evidence exists or until all elements are delivered. Additionally, the Company periodically enters into certain long term contracts to which SOP 81-1, "Accounting for Performance of Construction-Type and Certain Production-Type Contracts," is applied. For these agreements, revenue is recognized under a percentage of completion basis as appropriate measures of completion for each contract is achieved. The Company generates revenues from system sales, which include the licenses of software and sale of hardware, maintenance contracts and consulting contracts. Accordingly, revenue from software licensing F-9

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) arrangements is principally recognized upon delivery, subject to specified milestones and dates. Revenue from consulting services is recognized in the period in which services are performed. Revenue from hardware sales is recognized upon delivery. Revenue from maintenance contracts is recognized ratably over the term of the support period, which is typically one year. Any material anticipated contract losses are recognized in the period that they are determined. Deferred revenue is recorded to the extent that billings exceed revenue recognized under service contracts. Unbilled accounts receivable is recorded to the extent that revenue recognized exceeds billings under service contracts. In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin (SAB) No. 101 "Revenue Recognition in Financial Statements". The SAB formalizes positions the staff has expressed in speeches and comment letters. SAB 101 is effective no later than the fourth fiscal quarter of the fiscal year beginning after December 15, 1999. The Company is presently analyzing the impact, if any, that adherence to the SAB will have on its financial condition or results of operations. Research and Development Research and development costs are expensed as incurred. Software development costs incurred after the establishment of technological feasibility and until the product is available for general release are capitalized, provided recoverability is reasonably assured. Technological feasibility is established upon the completion of a working model. Software development costs, when material, are stated at the lower of unamortized cost or net realizable value. Net realizable value for each software product is assessed based on anticipated profitability applicable to revenues of the related product in future periods. Amortization is provided on a straight-line basis over three years and is included in cost of revenues. During 1997, 1998 and 1999, the Company capitalized $661,289, $885,154 and $124,640, respectively, of non web- based software development costs. Amortization expense of capitalized software for the years ended December 31, 1997, 1998 and 1999 was $277,996, $795,220 and $537,888, respectively. Costs related to the web-based software have not been capitalized since technological feasibility has not yet been achieved. Software development costs related to the development of the Company's web hosting capabilities are expensed or capitalized based upon the nature of the costs incurred in accordance with Statement of Position 98-1 "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use" (SOP 98- 1). Planning and feasibility costs are expensed as incurred. Cost of internal and external labor related to web infrastructure and applications are capitalized. Capitalized costs are amortized on a straight-line basis over their useful life. Maintenance and operating costs are expensed as incurred. As of December 31, 1998 and 1999 and June 30, 2000, the Company has not yet incurred any costs related to the development of web hosting and related capabilities. Concentration of Credit Risk Financial instruments that potentially subject the PC Business to concentration of credit risk consist primarily of trade accounts receivables. The customers are substantially all large integrated healthcare delivery enterprises principally located in the United States. To reduce credit risk, credit evaluations of the financial condition of its customers are performed. Although the PC Business is directly affected by the overall financial condition of the healthcare industry, management does not believe significant credit risk exists at December 31, 1999. The losses related to collection of accounts receivables have consistently been within management's expectations. Equipment Until 1999, CH did not maintain separate accountability for the purchase and usage of equipment, principally computer and related equipment. Accordingly, an equipment usage charge has been recognized in F-10

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) the accompanying 1997 and 1998 financial statements based on the estimated usage of IDX equipment by the PC Business personnel. In 1999, equipment being used by the PC Business was specifically identified and has been included at cost less accumulated depreciation in the statement of net assets as of December 31, 1999. During 1999, depreciation has been provided on this equipment by the straight-line method over the estimated useful lives of two to three years. Income Taxes The Company accounts for income taxes under the liability method as required by Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of differences between the tax and financial accounting of assets and liabilities at each year end. Deferred income taxes are based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. A valuation allowance is established when necessary to reduce deferred tax assets to the amounts expected to be realized. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. Stock-Based Compensation The Company adopted the disclosure-only provisions of SFAS No. 123, "Accounting for Stock-Based Compensation" for options granted to employees. As permitted by SFAS No. 123, the Company accounts for stock options granted to employees in accordance with Accounting Principles Board Opinion (APB) No. 25, "Accounting for Stock Issued to Employees," and has included the pro forma disclosures required by SFAS No. 123 for all periods presented. Stock options issued to non-employees, including IDX personnel who are not employees of CH, are accounted for under SFAS No. 123 and FASB Interpretation (FIN) No. 44 "Accounting for Certain Transactions involving Stock Compensation, an interpretation of APB Opinion No. 25." These transactions are accounted for based on the fair value of the goods or services received or on the fair value of the equity instruments issued, using the Black-Scholes methodology, dependent on which measure is more reliable. All expenses related to these transactions were recognized based upon the vesting of the options, generally at the date of grant. Accounting for Derivatives and Hedging Activities In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivatives and Hedging Activities" (SFAS No. 133) as amended by SFAS No. 137, which establishes accounting and reporting standards for derivative instruments, including derivative instruments embedded in other contracts, (collectively referred to as derivatives) and for hedging activities. SFAS No. 133 is effective for all fiscal quarters of fiscal years beginning after June 15, 2000. The Company is presently analyzing the impact, if any, that the adoption of SFAS No. 133 will have on its financial condition or results of operations. Segment Information In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 131, "Disclosures about Segments of an Enterprise and Related Information." The Company adopted SFAS No. 131 effective with the fiscal year ended December 31, 1998. SFAS No. 131 establishes standards for reporting information regarding operating segments in annual financial statements and requires selected information for those segments to be presented in interim financial reports issued to stockholders. SFAS No. 131 also establishes standards for related disclosures about major customers, products F-11

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) and services, and geographic areas. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision making group, in making decisions how to allocate resources and assess performance. The Company views its operations and manages its business as principally one segment, healthcare web-based information solutions that include software, hardware and related services. Substantially all of the Company's operations are in the United States. For the year ended December 31, 1997, four customers accounted for approximately 69% or more of the Company's revenues. For the year ended December 31, 1998, two customers accounted for approximately 46% or more of the Company's revenues. For the year ended December 31, 1999, three customers accounted for approximately 62% or more of the Company's revenues. As a result, the financial information disclosed herein represents all of the material financial information related to the Company's principal operating segment. Interim Reporting (unaudited) The interim unaudited financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission and in accordance with accounting principles generally accepted in the United States. Accordingly, certain information and footnotes disclosure normally included in annual financial statements have been omitted or condensed. In the opinion of management, all necessary adjustments (consisting of only normal recurring accruals) have been made to provide a fair presentation. 4. Financing Arrangements The net proceeds provided to the PC Business from IDX included in the accompanying financial statements represents a net balance as a result of various transactions between the PC Business and IDX. The amount represents IDX's investment in the PC Business. Interest at a rate of 9.0% has been charged on the net balance. The balance is primarily the result of the PC Business's participation in IDX's cash management program, wherein all of the PC Business's cash receipts are remitted to IDX and all operating expenses, including the allocation of certain costs and expenses described above, are funded by IDX. An analysis of transactions with IDX for each of the periods presented follows: December 31, -------------------------------------- 1997 1998 1999 ----------- ----------- ------------ Balance at beginning of year........ $(3,516,299) $(5,873,214) $ (9,830,247) Net cash remitted to IDX............ 2,293,218 1,506,999 1,069,694 Operating expenses..................

Benefit Plans Stock Option Plan Effective October 1, 1999, CH established a stock option plan to provide employees, consultants or advisors to CH and members of the Board the ability to acquire an ownership interest in CH. Options to employees under the plan generally vest 25% per year and expire ten years after issuance. As of December 31, 1999, CH reserved 2,500,000 shares of common stock for issuance under the Plan. At December 31, 1999, F-12

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) there were a total of 1,248,475 options granted under this plan. In connection with the Proposed Transaction, outstanding options of CH will be exchanged for options of Allscripts based on their fair value. In November 1999, options to purchase an aggregate of 1,232,725 shares of common stock, which vest immediately, were granted to IDX personnel who were not employees of CH at an exercise price of $10 per share. Based on the provisions of FIN No. 44, the Company has recognized a compensation charge of $4,561,083 relating to these option grants. The Compensation Committee has the right, in its discretion, to select the individuals eligible to receive awards, determine the terms and conditions of the awards granted, accelerate the vesting schedule of any award and generally administer and interpret the plan. The Compensation Committee determines the exercise prices of options granted under the 1999 Stock Option and Incentive Plan. Under present law, incentive stock options and options intended to qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986 may not be granted at an exercise price less than the fair market value of the common stock on the date of grant or less than 110% of the fair market value in the case of incentive stock options granted to optionees holding more than 10% of the voting power. Non-qualified stock options may be granted at prices that are less than the fair market value of the underlying shares on the date granted. Options, other than those granted to IDX personnel described above, are typically subject to vesting schedules, terminate ten years from the date of grant and may be exercised for specified periods after the termination of the optionee's employment or other service relationship with the Company. Upon the exercise of options, the option exercise price must be paid in full either in cash or other instrument acceptable to the committee or by delivery of shares of common stock that have been owned by the optionee free of restrictions for at least six months. The 1999 Stock Option and Incentive Plan and all awards issued under the plan will terminate upon a merger, reorganization or consolidation, the sale of all or substantially all of the Company's assets or all of the outstanding capital stock or a liquidation or other similar transaction, unless CH and the other parties to such transactions have agreed otherwise. A summary of the Company's stock option activity and related information is as follows at December 31: June 30, 2000 1999 (unaudited) ------------------ ------------------ Weighted Weighted Average Average Exercise Exercise Options Price Options Price --------- -------- --------- -------- Outstanding--beginning of period.......... -- -- 1,248,475 $10.00 Granted................................... 1,248,475 $10.00 532,775 10.70 Exercised................................. -- -- -- -- Cancelled................................. -- -- -- -- --------- ------ --------- ------ Outstanding--end of period................ 1,248,475 $10.00 1,781,250 $10.21 ========= ====== ========= ====== Exercisable--end of period................ 1,236,663 1,405,107 ========= ========= Available for grant--end of period........ 1,251,525 718,750 ========= ========= Weighted--average fair value of options granted during the period................ $ 3.78 $ 4.58 ====== ====== F-13

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) The following table summarizes information about stock options outstanding at December 31, 1999: Outstanding Exercisable ------------------------------------------ -------------------------- Remaining Weighted Weighted Range of Contractual Average Average Exercise Number Life Exercise Number of Exercise Price Outstanding (Years) Price Exercisable Price - -------- ----------- ----------- -------- ----------- -------- $10.00 1,248,475 9.9 $10.00 1,236,663 $10.00 Pro forma disclosure information regarding net loss is required by SFAS No. 123 and has been determined as if the Company has accounted for its employee stock options under the fair value method of that statement. The fair value of these options was estimated at the date of grant using the Black Scholes option pricing model with the following weighted average assumptions for 1999: risk- free interest rates of 6.07%; dividend yields of 0%; and a weighted average life of the options of two years and volatility of 60.27%. Option valuation models require the input of highly subjective assumptions. The Company's employee stock options have characteristics significantly different from those of traded stock options and because changes in subjective assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the vesting period of such options. The pro forma net loss, as if compensation cost for the Plan had been determined based on the fair value at the grant date in accordance with the provisions of SFAS No. 123, is approximately $6,700 higher than the actual reported net loss for the year ended December 31, 1999. The effects on 1999 pro forma net loss of expensing the estimated fair value of stock options and shares issued to employees pursuant to the 1999 Stock Option and Incentive Plan are not necessarily representative of the effects on reporting the results of operations for future years. 401(K) Retirement Savings Plan The Company provides its employees a 401(k) retirement savings plan benefit as a participating subsidiary in the IDX Systems Corporation Retirement Income Plan that covers all full-time employees eligible to participate. Under the IDX plan, employees are eligible to participate in the plan on the first day of the month following the date of employment. The Company matches participant contributions up to 3%. 6. Income Taxes A reconciliation of the federal statutory rate to the effective income tax rate during 1997, 1998, and 1999 as if the Company were an unaffiliated Company for income tax reporting purposes is as follows: 1997 1998 1999 ----- ----- ----- Tax at federal statutory rate........................ 34.0% 34.0% 34.0% State taxes, net of federal benefit.................. 5.4 5.4 5.4 Change in valuation allowance........................ (39.4) (39.4) (39.4) ----- ----- ----- 0.0% 0.0% 0.0% ===== ===== ===== F-14

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's deferred tax assets as of December 31, 1998 and 1999 are shown below. Years ended December 31, ---------------------- 1998 1999 ---------- ---------- Deferred tax assets: Net operating loss carryforward................. $3,584,838 $7,386,696 ---------- ---------- Total deferred tax assets......................... 3,584,838 7,386,696 Valuation allowance............................... (3,584,838) (7,386,696) ---------- ---------- Net deferred tax assets........................... $ 0 $ 0 ========== ========== At December 31, 1999, the Company's net operating loss carry forward for federal income tax purposes would be approximately $19.0 million, if the Company were an unaffiliated Company for income tax reporting purposes. For income tax provision purposes a valuation allowance has been recorded for the full amount of the net operating loss carryforward due to the uncertainty of recovery. 7. Commitments and Contingencies The Company is from time to time involved in routine litigation incidental to the conduct of its business. The Company believes that routine litigation currently pending will not have a material adverse effect on the financial condition or results of operations of the PC Business. In February 2000, IDX and the Company were notified of a contractual dispute with respect to an exclusivity provision from a supply contract with a third party. In September 2000, IDX, the Company and the third party settled the dispute and related litigation. In connection with the settlement and defense of the litigation, IDX and the Company incurred total costs of approximately $1,034,000. The settlement of the litigation and the legal costs incurred as of June 30, 2000 totaling $936,736 have been recognized in the statement of operations as of June 30, 2000. 8. Year 2000 Costs (unaudited) In late 1999, the Company completed its remediation and testing of systems to become Year 2000 ready. As a result of those planning and implementation efforts, PC experienced no significant disruptions in mission critical information technology and non-information technology systems and believes those systems successfully responded to the Year 2000 date change. No significant costs were incurred in connection with remediating its systems. PC is not aware of any material problems resulting from Year 2000 issues, either with its products, its internal systems, or the products and services of third parties. PC will continue to monitor its mission critical computer applications and those of its suppliers and vendors throughout the year 2000 to ensure that any latent Year 2000 matters that may arise are addressed promptly. 9. Subsequent Events On January 10, 2000, CH sold 2,542,243 shares of Series A Convertible Preferred Stock to Pequot Private Equity Fund II, L.P. for a purchase price of $29,998,467 (representing approximately 9.0% of the outstanding shares of stock, on an as converted basis, of CH). On January 31, 2000, CH sold additional 177,186 shares of Series A Convertible Preferred Stock to other shareholders for a purchase price of $2,090,795. Under certain circumstances, the Series A Convertible Preferred Stock is convertible into common stock of CH. Any unexpended proceeds from the sale of CH Series A Convertible Preferred Stock will be distributed to IDX prior to the Proposed Transaction and accordingly have not been reflected on the accompanying statements of net assets. F-15

PHYSICIAN CHANNEL BUSINESS OF CHANNELHEALTH INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) On January 24, 2000, IDX and CH announced a strategic alliance with Healtheon/WebMD, and CH announced, subject to regulatory approval, an investment in Healtheon/WebMD. As a result of the anticipated extensive regulatory review process, among other considerations, the agreement with Healtheon/WebMD was revised to exclude the investment by CH in Healtheon/WebMD. On June 8, 2000, the new agreement, which is not subject to regulatory approval, included the following terms. Healtheon/WebMD will provide electronic transaction services for IDX's practice management systems and CH Internet services. Healtheon/WebMD's content will be integrated into CH's Physician Channel and Patient Channel Internet services. Healtheon/WebMD will commit to a multi-million dollar co-branded marketing campaign promoting IDX and CH products and services that incorporate Healtheon/WebMD content and transactions. In September 2000, Healtheon/WebMD indicated that it may modify or terminate certain business relationships, and in October 2000, indicated to CH that it would seek to terminate the new agreement. As of November 3, 2000, no proposal for a renegotiated agreement, and no notice of termination or breach of the new agreement, has been received from Healtheon/WebMD by CH. F-16

As of the Effective Time and without any action on the part of the holders thereof, all such shares of ChannelHealth Stock shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder (each, a "ChannelHealth Stockholder") of a certificate or certificates that immediately prior to the Effective Time represented outstanding shares of ChannelHealth Stock (the "ChannelHealth Certificates" and together with the Allscripts Certificates, the "Certificates") shall cease to have any rights with respect thereto, except the right to receive (i) the applicable ChannelHealth Merger Consideration, (ii) if applicable, certain dividends and other distributions in accordance with Section 2.3(c), without interest, (iii) if applicable, cash in lieu of fractional shares of Parent Common Stock in accordance with Section 2.3(e), without interest and (iv) Earnout Shares, if applicable.

(d) ChannelHealth Stock Options. As soon as practicable following the date of this Agreement, Parent shall take such action as may be required to effect the following provisions of this Section 2.2(d). As of the time of Closing each option to purchase shares of ChannelHealth Common Stock (a "ChannelHealth Option") which is then outstanding shall be assumed by Parent and converted into an option (an "Assumed Option") to purchase the number of shares of Parent Common Stock (rounded up to the nearest whole share) equal to (i) the number of shares of ChannelHealth Common Stock subject to such option multiplied by (ii) the ChannelHealth Exchange Ratio, at an exercise price per share of Parent Common Stock (rounded down to the nearest penny) equal to (A) the former exercise price per share of ChannelHealth Common Stock under such option immediately prior to the Closing divided by (B) the ChannelHealth Exchange Ratio; provided, however, that in the case of any ChannelHealth Option to which Section 421 of the Code applies by reason of its qualification under Section 422 of the Code, the conversion formula shall be adjusted, if necessary, to comply with Section 424(a) of the Code. Except as provided above, the Assumed Options shall be subject to the same terms and conditions (including expiration date, vesting and exercise provisions) as were applicable to the converted ChannelHealth Option immediately prior to the Closing. As soon as practicable after the Effective Time, Parent shall deliver to the holders of Assumed Options appropriate notices setting forth such holders' rights pursuant to such Assumed Options, as amended by this Section 2.2(d), and the agreements evidencing such Assumed Options shall continue in effect on the same terms and conditions (subject to the amendments provided for in this Section 2.2(d) and such notice). Parent shall take such actions as are reasonably necessary for the assumption of the ChannelHealth Options pursuant to this Section 2.2(d), including the reservation, 4

issuance and listing of shares of Parent Common Stock as is necessary to effectuate the transactions contemplated by this Section 2.2(d). Parent shall prepare and file with the SEC a registration statement on Form S-8 or other appropriate form with respect to the shares of Parent Common Stock subject to the Assumed Options as soon as practicable, and in any event within thirty (30) days after the Closing Date, and to maintain the effectiveness of such registration statement or registration statements covering such Assumed Options (and maintain the current status of the prospectus or prospectuses contained therein) for so long as any Assumed Options remain outstanding. (e) ChannelHealth Dissenting Shares. (i) For purposes of this Agreement, "ChannelHealth Dissenting Shares" means shares of ChannelHealth Common Stock held as of the Effective Time by a stockholder who has not voted such shares of ChannelHealth Common Stock in favor of the adoption of this Agreement and the ChannelHealth Merger and with respect to which appraisal shall have been duly demanded and perfected in accordance with Section 262 of the DGCL and not effectively withdrawn or forfeited prior to the Effective Time. ChannelHealth Dissenting Shares shall not be converted into or represent the right to receive shares of Parent Common Stock, unless such stockholder shall have forfeited his, her or its right to appraisal under the DGCL or properly withdrawn his, her or its demand for appraisal. If such stockholder has so forfeited or withdrawn his, her or its right to appraisal of ChannelHealth Dissenting Shares, then (A) as of the occurrence of such event, such holder's ChannelHealth Dissenting Shares shall cease to be ChannelHealth Dissenting Shares and shall be converted into and represent the right to receive the shares of Parent Common Stock issuable in respect of such shares of ChannelHealth Common Stock pursuant to Section 2.2(b), and (B) promptly following the occurrence of such event, Parent shall deliver to the Exchange Agent a certificate representing the shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(b). (ii) ChannelHealth shall give Parent (A) prompt notice of any written demands for appraisal of any shares of ChannelHealth Common Stock, withdrawals of such demands, and any other instruments that relate to such demands received by ChannelHealth and (B) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. ChannelHealth shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal of shares of ChannelHealth Common Stock or offer to settle or settle any such demands. 2.3 Exchange of Certificates. (a) Exchange Agent. Prior to the Effective Time, Parent, Allscripts and ChannelHealth shall enter into an agreement with such bank or trust company as may be designated by Allscripts and ChannelHealth to act as exchange agent for the purpose of exchanging Certificates for the applicable Merger Consideration (the "Exchange Agent"). At or prior to the Effective Time, Parent shall deposit with the Exchange Agent, in trust for the benefit of the holders of shares of Allscripts Common Stock and ChannelHealth Stock, for exchange in accordance with this Article II through the Exchange Agent, Parent Certificates representing the number of whole shares of Parent Common Stock issuable pursuant to Section 2.1 in exchange for outstanding shares of Allscripts Common Stock and issuable pursuant to Section 2.2 in exchange for outstanding shares of ChannelHealth Stock. Parent Certificates deposited with the Exchange Agent shall hereinafter be referred to as the "Exchange Fund". Parent shall make available to the Exchange Agent, from time to time as required after the Effective Time, cash necessary to pay dividends and distributions in accordance with Section 2.3(c) and to make payments in lieu of any fractional shares in accordance with Section 2.3(e). (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a Certificate whose shares were converted into the Allscripts Merger Consideration pursuant to Section 2.1, or the ChannelHealth Merger Consideration pursuant to Section 2.2 (collectively, the "Merger Consideration"), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Allscripts and ChannelHealth may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates 5

in exchange for the applicable Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a Parent Certificate representing that number of whole shares of Parent Common Stock which such holder has the right to receive pursuant to the provisions of this Article II, certain dividends or other distributions, if any, in accordance with Section 2.3(c) and cash in lieu of any fractional share in accordance with Section 2.3(e), and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of ChannelHealth Stock that is not registered in the transfer records of ChannelHealth, or of Allscripts Common Stock that is not registered in the transfer records of Allscripts, a Parent Certificate representing the proper number of shares of Parent Common Stock may be issued to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such issuance shall pay any transfer or other non-income taxes required by reason of the issuance of shares of Parent Common Stock to a person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.3, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable Merger Consideration that the holder thereof has the right to receive pursuant to the provisions of this Article II, if applicable, certain dividends or other distributions in accordance with Section 2.3(c) and, if applicable, cash in lieu of any fractional share in accordance with Section 2.3(e). No interest will be paid or will accrue on any cash payable to holders of Certificates pursuant to the provisions of this Article II. (c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Parent Common Stock with a record date on or after the Closing Date shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.3(e), and all such dividends, other distributions and cash in lieu of fractional shares of Parent Common Stock shall be paid by Parent to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Certificate in accordance with this Article II. Subject to the effect of applicable escheat or similar laws, following surrender of any such Certificate there shall be paid to the holder of the Parent Certificate representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date on or after the Closing Date theretofore paid with respect to such whole shares of Parent Common Stock and the amount of any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.3(e) and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date on or after the Closing Date but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock. Parent shall make available to the Exchange Agent cash for these purposes. (d) No Further Ownership Rights in Allscripts Common Stock or ChannelHealth Stock. All shares of Parent Common Stock issued, and all cash paid, upon the surrender for exchange of Certificates in accordance with the terms of this Article II shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Allscripts Common Stock or ChannelHealth Stock theretofore represented by such Certificates, subject, however, to the applicable Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Closing Date that may have been authorized or made by Allscripts on such shares of Allscripts Common Stock or by ChannelHealth on such shares of ChannelHealth Stock that remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of the applicable Surviving Corporation of the shares of Allscripts Common Stock or ChannelHealth Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the applicable Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II, except as otherwise provided by law. 6

(e) No Fractional Shares. (i) No Parent Certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution of Parent shall relate to such fractional share interests and such fractional share interests will not entitle the owner thereof to vote or to any rights of a stockholder of Parent. (ii) The Surviving Corporations shall pay each former holder of Allscripts Common Stock or ChannelHealth Stock, as applicable, an amount in cash equal to the product obtained by multiplying (A) the fractional share interest to which such former holder (after taking into account all shares of Allscripts Common Stock or ChannelHealth Stock held at the Effective Time by such holder) would otherwise be entitled by (B) the closing price for a share of Parent Common Stock as reported on the Nasdaq Stock Market, Inc. (the "Nasdaq") (as reported in The Wall Street Journal, or, if not reported thereby, any other authoritative source) on the first trading day following the Closing Date. (iii) As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Allscripts Common Stock and ChannelHealth Stock with respect to any fractional share interests, the Exchange Agent will make available such amounts to such holders of Allscripts Common Stock and ChannelHealth Common Stock subject to and in accordance with the terms of Section 2.3(c). (f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates for six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to Parent for payment of their claim for the applicable Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to Parent Common Stock. (g) No Liability. None of Parent, Allscripts, ChannelHealth or the Exchange Agent shall be liable to any person in respect of any shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to seven years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration, any cash payable to the holder of such Certificate pursuant to this Article II or any dividends or distributions payable to the holder of such Certificate would otherwise escheat to or become the property of any governmental body or authority) any such Merger Consideration or cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable law, become the property of Parent, free and clear of all claims or interest of any person previously entitled thereto. (h) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent. 2.4 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the related Surviving Corporation, the posting by such person of a bond in such reasonable amount as the related Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration and, if applicable, any cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Parent Common Stock deliverable in respect thereof, in each case pursuant to this Agreement. 2.5 Withholding Rights. Each of the Surviving Corporations and Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Allscripts Common Stock or ChannelHealth Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or 7

any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by either of the Surviving Corporations or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Allscripts Common Stock or ChannelHealth Stock in respect of which such deduction and withholding was made by either of the Surviving Corporations or Parent, as the case may be. 2.6 Stockholders' Representative. (a) In order to efficiently administer the transactions contemplated hereby, including (i) the waiver of any condition to the obligation of ChannelHealth to consummate the transactions contemplated hereby, (ii) any adjustment in the Cash Reserves (as defined in Section 5.1(d) below) pursuant to Article V, (iii) the ability to consent, approve and agree on behalf of the holders of ChannelHealth Stock at the Effective Time (the "ChannelHealth Stockholders") to the calculation of the Earnout Revenue pursuant to Article III and (iv) the orderly distribution of the ChannelHealth Merger Consideration and, if applicable, the Earnout Shares from Parent to the ChannelHealth Stockholders, the ChannelHealth Stockholders (other than IDX) hereby designate IDX as their representative (in such capacity, the "Stockholders' Representative") in the manner described in Section 2.6(d) below. (b) The ChannelHealth Stockholders hereby authorize the Stockholders' Representative (i) to make all decisions on behalf of the ChannelHealth Stockholders relating to any adjustment in the Cash Reserves pursuant to Section 4.2, (ii) to make all decisions and grant all consents and approvals on behalf of the ChannelHealth Stockholders relating to the calculation of the Earnout Revenue and any distribution of Earnout Shares pursuant to Article III, (iii) to take all action necessary in connection with the waiver of any condition to the obligation of ChannelHealth to consummate the transactions contemplated hereby, (iv) to determine the ChannelHealth Stockholders to whom ChannelHealth Merger Consideration shall be distributed the amount of consideration to be so distributed, and the address of such ChannelHealth Stockholders, (v) to give and receive all notices required to be given under this Agreement and (vi) to take any and all additional action as is contemplated to be taken by or on behalf of the ChannelHealth Stockholders by the terms of this Agreement. (c) All decisions and actions by the Stockholders' Representative shall be binding upon all of the ChannelHealth Stockholders and no ChannelHealth Stockholder shall have the right to object, dissent, protest or otherwise contest the same. (d) By virtue of the adoption of this Agreement and the approval of the ChannelHealth Merger by the ChannelHealth Stockholders at a meeting of the ChannelHealth Stockholders (or by written consent in lieu of a meeting) pursuant to, and in accordance with, the applicable provisions of the DGCL, each ChannelHealth Stockholder that is not a holder of ChannelHealth Dissenting Shares hereby agrees that: (i) Parent shall be able to rely conclusively on the instructions and decisions of the Stockholders' Representative as to any actions required or permitted to be taken by the Stockholders' Representative hereunder, and no party hereunder shall have any cause of action against Parent or Allscripts to the extent the Parent has relied upon the instructions or decisions of the Stockholders' Representative; (ii) all actions, decisions and instructions of the Stockholders' Representative shall be conclusive and binding upon all of the ChannelHealth Stockholders and no ChannelHealth Stockholder shall have any cause of action against the Stockholders' Representative for any action taken, decision made or instruction given by the Stockholders' Representative under this Agreement, except for fraud or willful breach of this Agreement by the Stockholders' Representative; (iii) the provisions of this Section 2.6 are independent and severable, are irrevocable and coupled with an interest and shall be enforceable notwithstanding any rights or remedies that any ChannelHealth Stockholder may have in connection with the transactions contemplated by this Agreement; (iv) the provisions of this Section 2.6 shall be binding upon the executors, heirs, legal representatives, personal representatives, successor trustees, and successors of each ChannelHealth Stockholder, and any 8

references in this Agreement to a ChannelHealth Stockholder or the ChannelHealth Stockholders shall mean and include the successors to the ChannelHealth Stockholders' rights hereunder, whether pursuant to testamentary disposition, the laws of descent and distribution or otherwise; and (v) All fees and expenses incurred by the Stockholders' Representative shall be paid by the ChannelHealth Stockholders (other than holders of ChannelHealth Dissenting Shares) in proportion to their ownership of ChannelHealth Stock immediately prior to the Effective Time. 2.7 Effect of ChannelHealth Stockholders' Approval of the ChannelHealth Merger. Subject to the provisions of the last sentence of this Section 2.7, the adoption of this Agreement and the approval of the ChannelHealth Merger by the ChannelHealth Stockholders at a meeting of the ChannelHealth Stockholders (or by written consent in lieu of a meeting) pursuant to, and in accordance with, the applicable provisions of the DGCL shall be deemed to constitute approval by each ChannelHealth Stockholder individually, to the same extent as if such ChannelHealth Stockholder were a party to this Agreement, of (i) all of the provisions of this Agreement that pertain to the ChannelHealth Stockholders and that impose liabilities, obligations or burdens on the ChannelHealth Stockholders or that limit the rights of the ChannelHealth Stockholders (including, without limitation, with respect to the rights of the ChannelHealth Stockholders to receive all or any portion of the ChannelHealth Merger Consideration), (ii) the appointment of the Stockholders' Representative, (iii) the grant to the Stockholders' Representative of all of the powers, rights and privileges contemplated under this Agreement, (iv) the provisions of this Agreement concerning the replacement and substitution of the Stockholders' Representative and (v) any and all provisions of this Agreement that contemplate, authorize or provide for any adjustment in the ChannelHealth Merger Consideration payable to the ChannelHealth Stockholders pursuant to the ChannelHealth Merger (including, without limitation, any provisions of this Agreement that specify or provide a procedure for determining or implementing any such increase, reduction or other adjustment in the ChannelHealth Merger Consideration). Notwithstanding the foregoing, the provisions of this Section 2.7 shall not apply to those ChannelHealth Stockholders that duly exercise the appraisal rights afforded to dissenting stockholders pursuant to Section 262 of the DGCL. 2.8 Further Assurances. At and after the Effective Time, the officers and directors of the Surviving Corporations shall be authorized to execute and deliver, in the name and on behalf of Allscripts or ChannelHealth, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Allscripts or ChannelHealth, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporations any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporations as a result of, or in connection with, the Mergers. ARTICLE III Earnout 3.1 Earnout. (a) In further consideration of the ChannelHealth Merger, the Parent shall issue and deliver or cause to be issued and delivered to the Stockholders' Representative for the benefit of the ChannelHealth Stockholders on or before March 31, 2003 (the "Earnout Date"), if the following conditions are satisfied: (i) if the Gross Qualifying Revenues (as defined below) to Parent, or any Affiliate of Parent from January 1, 2002 to December 31, 2002 (the "Earnout Revenue") is greater than or equal to $180 million but less than or equal to $210 million, .03167 additional shares of Parent Common Stock for each share of ChannelHealth Stock held at the Effective Time (subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Parent Common Stock or the Allscripts Common Stock between the date of this Agreement and the Earnout Date); (ii) if Earnout Revenue is greater than $210 million, .04750 additional shares of Parent Common Stock for each share of ChannelHealth Stock held at the Effective Time (subject to equitable adjustment in 9

the event of any stock split, stock dividend, reverse stock split or similar event affecting the Parent Common Stock or the Allscripts Common Stock between the date of this Agreement and the Earnout Date); (iii) if Earnout Revenue is less than $180 million, no additional shares of Parent Common Stock; or (iv) if, prior to December 31, 2002, Parent sells, transfers or otherwise disposes of, or causes any of its Affiliates to sell, transfer or otherwise dispose of all or substantially all of its business or intellectual property related to physician-focused, internet based services that automate clinical, financial and administrative functions involved in the healthcare delivery process, .04750 additional shares of Parent Common Stock for each share of ChannelHealth Stock held at the Effective Time (subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Parent Common Stock or the Allscripts Common Stock between the date of this Agreement and the Earnout Date). Any shares of Parent Common Stock issued by Parent pursuant to this Section 3.1(a) are referred to in this Agreement as the "Earnout Shares." Parent shall issue the Parent Certificates representing the Earnout Shares, if any, pursuant to this Section 3.1(a) in the name of each ChannelHealth Stockholder and representing a number of shares of Parent Common Stock equal to such ChannelHealth Stockholder's percentage interest in the Earnout Shares, which percentage interests shall be based upon each holder's pro rata interest in all shares of ChannelHealth Stock issued and outstanding immediately prior to the Effective Time. No Parent Certificates or scrip representing fractional shares of Parent Common Stock shall be issued pursuant to this Section 3.1(a), and in lieu thereof the ChannelHealth Stockholders entitled thereto will be paid cash for their fractional share interests pursuant to the procedures set forth in Section 2.3(e). Notwithstanding anything herein to the contrary, no ChannelHealth Stockholder shall be entitled to any Earnout Shares in respect of such ChannelHealth Stockholder's ownership of ChannelHealth Dissenting Shares. (b) For the purposes of this Agreement, the following terms shall have the respective meanings set forth below: (i) "Gross Qualifying Revenues" means revenues from Qualifying Sales (as defined below) which are recognized by Parent or any Affiliate of Parent in accordance with GAAP, prior to any reductions of any kind, including reductions of commissions paid to IDX. (ii) "Qualifying Sales" are sales generated from the service lines set forth on Schedule 3.1(b)(ii), less the commissions payable to IDX set forth on such Schedule. (c) Parent will report Gross Qualifying Revenues to the Stockholders' Representative on a monthly basis during the period from January 1, 2002 through December 31, 2002 not later than 30 days after the end of the month. After receiving a report from Parent and upon 15 business days written notice, up to four times per year, the Stockholders' Representative shall have the right at its expense to have reasonable access, during normal business hours, to inspect the books and records of Parent and any Affiliate of Parent relating to Gross Qualifying Revenues for the limited purpose of verifying Parent's compliance with this Article III. Parent shall make such books and records available at its offices in Libertyville, Illinois and such books and records shall be made available in the manner which they are regularly maintained by Parent. In addition, at the request of the Stockholders' Representative in accordance with this Section 3.1(c), Parent shall also make photocopies of such books and records available at IDX's primary Vermont office for inspection by the Stockholders' Representative. (d) Following receipt from Parent of the final report of Gross Qualifying Revenues as provided in Section 3.1(c), the Stockholders' Representative shall have a period of 20 days after delivery to present in writing to Parent any objections thereto, which objections shall be set forth in reasonable detail. If no objections are raised within such 20-day period, the report shall be deemed accepted and approved by the Stockholders' Representative. However, in the event of a dispute, the parties shall follow the procedures set forth in Sections 5.1(c) and 5.1(e). 10

3.2 Registration of Earnout Shares. If any Earnout Shares are issued pursuant to Section 3.1, Parent shall file with the Commission, within five business days following the Earnout Date, a non-exclusive "shelf" registration statement pursuant to Rule 415 under the Securities Act covering the resale to the public by the holders of all of the Earnout Shares on a continuous basis (the "Earnout Registration Statement"). The Earnout Registration Statement will be on Form S-3 unless Parent ceases to be eligible to register the Earnout Shares for resale on such Form, in which case such registration will be on another appropriate form in accordance herewith. Parent shall use its best efforts to cause the Earnout Registration Statement to be declared effective by the Commission as soon as practicable after the filing thereof. Parent shall cause the Earnout Registration Statement to remain effective until the second anniversary of the filing thereof or such earlier time as all of the Earnout Shares covered by the Earnout Registration Statement have been sold pursuant thereto. 3.3 Registration Procedures. In connection with Parent's registration obligations hereunder, Parent will: (a) Not less than two business days prior to the filing of the Earnout Registration Statement, or any related prospectus or amendment or supplement thereto (but excluding any documents incorporated or deemed to be incorporated by reference), furnish to each ChannelHealth Stockholder and its counsel copies of all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review of each ChannelHealth Stockholder and its counsel. Parent will in good faith seek to address any questions or issues raised by any ChannelHealth Stockholder or its counsel as a result of such review. (b) (i) Prepare and file with the Commission such amendments, including post-effective amendments, as may be necessary to keep the Earnout Registration Statement continuously effective for resale of all of the Earnout Shares; (ii) cause the prospectus included therein to be amended or supplemented as required; (iii) promptly provide each ChannelHealth Stockholder and its counsel with copies of all correspondence from and to the Commission relating to the Earnout Registration Statement; and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Earnout Shares covered by the Earnout Registration Statement. (c) Notify each ChannelHealth Stockholder and its counsel immediately: (i) when a prospectus, prospectus supplement or post-effective amendment to the Earnout Registration Statement is proposed to be filed; (ii) on effectiveness of the Earnout Registration Statement or any post-effective amendment; (iii) of any request by the Commission, or other federal or state governmental authority, for amendments or supplements to the Earnout Registration Statement or prospectus or for additional information; (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Earnout Registration Statement or the initiation of any proceedings for that purpose; (v) of the receipt by Parent of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Earnout Shares for sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose; and (vi) of the occurrence of any event that makes any statement made in the Earnout Registration Statement or prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to the Earnout Registration Statement, prospectus or other documents so that such document will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. (d) Furnish to each ChannelHealth Stockholder and its counsel without charge (i) at least one conformed copy of each Earnout Registration Statement and amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits to the extent requested reasonably promptly after the filing of such documents with the Commission, and (ii) as many copies of the prospectus or prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request; and Parent hereby consents to the use of such prospectus and each amendment or supplement thereto by the ChannelHealth Stockholders and any underwriters in connection with the offering and sale of the Earnout Shares covered by such prospectus and any amendment or supplement thereto. 11

(e) Use its best efforts to register or qualify the Earnout Shares covered by the Earnout Registration Statement under the securities laws of each jurisdiction as any ChannelHealth Stockholder may reasonably request; provided, however that Parent will not be required in connection with this paragraph (e) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction. (f) If Parent has delivered preliminary or final prospectuses to the ChannelHealth Stockholders and after having done so the prospectus is amended to comply with the requirements of the Securities Act, promptly notify each ChannelHealth Stockholder and promptly provide each ChannelHealth Stockholder with revised or supplemented prospectuses. (g) Pay the following expenses incurred in complying with Sections 3.2 and 3.3: all registration and filing fees, exchange listing fees, fees and expenses of counsel for Parent, and fees and expenses of accountants for Parent, but excluding any brokerage fees, selling commissions or underwriting discounts and legal fees incurred by each ChannelHealth Stockholder in connection with sales under the Earnout Registration Statement. 3.4 Requirements of ChannelHealth Stockholders. Each ChannelHealth Stockholder shall furnish to Parent in writing such information regarding such ChannelHealth Stockholder and the proposed sale of Earnout Shares by such ChannelHealth Stockholder as is required by law to be disclosed in the Earnout Registration Statement. 3.5 Indemnification and Contribution. (a) Indemnification by Parent. Parent will indemnify and hold harmless each ChannelHealth Stockholder, its agents (including any underwriters retained by such ChannelHealth Stockholder in connection with the offer and sale of Earnout Shares) and any directors, officers and employees of any such Person, each Person who controls any such Person (within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and the directors, officers, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all debts, obligations and other liabilities, monetary damages, fines, fees, penalties, interest obligations, deficiencies, losses, costs and expenses (including without limitation reasonable attorneys' fee and expenses) (collectively, "Damages") arising out of or relating to any untrue or alleged untrue statement of a material fact contained in the Earnout Registration Statement, any prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding such ChannelHealth Stockholder furnished in writing to Parent by such ChannelHealth Stockholder expressly for use therein or by such ChannelHealth Stockholder's failure to deliver a copy of the Earnout Registration Statement or prospectus or amendment or supplement thereto. Parent will notify each ChannelHealth Stockholder promptly of the institution, threat or assertion of any proceeding of which Parent is aware in connection with the subject matter of this Section 3.5. (b) Indemnification by the ChannelHealth Stockholders. Each ChannelHealth Stockholder will indemnify and hold harmless Parent, the directors, officers, agents and employees of Parent, each person who controls Parent (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), and the directors, officers, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all Damages arising solely out of or relating solely to any untrue or alleged untrue statement of a material fact contained in the Earnout Registration Statement, any prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising solely out of or relating solely to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, to the extent, but only to the extent, that such untrue statement or omission is contained in any information regarding such 12

ChannelHealth Stockholder so furnished in writing by such ChannelHealth Stockholder to Parent specifically for inclusion in the Earnout Registration Statement or such prospectus. In no event will the liability of any ChannelHealth Stockholder hereunder be greater in amount than the net proceeds actually received by such ChannelHealth Stockholder from the sale of Earnout Shares pursuant to the Earnout Registration Statement. Each ChannelHealth Stockholder will notify Parent promptly of the institution, threat or assertion of any proceeding of which such ChannelHealth Stockholder is aware in connection with the subject matter of this Section 3.5. (c) Conduct of Indemnification Proceedings. A party entitled, or seeking to assert rights, to indemnification under this Section 3.5 (an "Indemnified Party") shall give written notification to the party from whom indemnification is sought (an "Indemnifying Party") of the commencement of any action, suit or proceeding relating to a third-party claim for which indemnification pursuant to this Section 3.5 may be sought or, if earlier, upon the assertion of any such claim by a third party. Such notification shall be given within 20 days after receipt by the Indemnified Party of notice of such action, suit, proceeding or claim, and shall describe (to the extent known by the Indemnified Party) the facts constituting the basis for such action, suit, proceeding or claim and the amount of the claimed damages; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent the Indemnifying Party thereby is prejudiced. Within 30 days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such action, suit, proceeding or claim with counsel reasonably satisfactory to the Indemnified Party. If the Indemnifying Party does not so assume control of such defense, the Indemnified Party shall control such defense. The Party not controlling such defense (the "Non-controlling Party") may participate therein at its own expense; provided that if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim, the reasonable fees and expenses of counsel to the Indemnified Party shall be considered "Damages" for purposes of this Agreement; provided, however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one counsel per jurisdiction for all Indemnified Parties. The Party controlling such defense (the "Controlling Party") shall keep the Non- controlling Party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such action, suit, proceeding or claim (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such action, suit, proceeding or claim. The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any such action, suit, proceeding or claim that does not include a complete release of the Indemnified Party from all liability with respect thereto or that imposes any liability or obligation on the Indemnified Party without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld or delayed. The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party. (d) Contribution. If a claim for indemnification under Section 3.5(a) or 3.5(b) is unavailable to an Indemnified Party because of a failure or refusal of a governmental authority to enforce such indemnification in accordance with its terms (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or 13

Indemnified Party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any losses shall be deemed to include any reasonable attorneys' or other reasonable fees or expenses incurred by such party in connection with any proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 3.5 was available to such party in accordance with its terms. The Parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 3.5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 3.5(d), no ChannelHealth Stockholder shall be required to contribute any amount in excess of the amount by which the net proceeds actually received by such ChannelHealth Stockholder from the sale of Earnout Shares pursuant to the Earnout Registration Statement exceeds the amount of any damages that such ChannelHealth Stockholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (e) the indemnity and contribution agreements contained in this Section 3.5 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties. 3.6 Registrations on behalf of Other Holders. Parent may, at its election, include securities of other holders of Parent's securities in the Earnout Registration Statement. 3.7 Assignment of Rights. No ChannelHealth Stockholder may assign any of its rights under Section 3.2 through 3.7 except in connection with the transfer of some or all of its Earnout Shares to a child or spouse, or trust or other entity for their benefit; provided, however, each such transferee agrees in a written instrument delivered to Parent to be bound by the provisions of Section 3.2 through 3.7. Any such permitted transferee shall be deemed to be a "ChannelHealth Stockholder" for purposes of Section 3.2 through 3.7 3.8 Blackouts. Anything in this Agreement to the contrary notwithstanding, it is understood and agreed that Parent shall not be required to keep any Earnout Registration Statement effective or useable for offers and sales of the Earnout Shares, file a post effective amendment to an Earnout Registration Statement or any prospectus supplement or to supplement or amend any Earnout Registration Statement, if Parent is then involved in discussions concerning, or otherwise engaged in, any material financing, offering or investment, acquisition or divestiture transaction or other material business purpose if Parent determines in good faith that the making of such a filing, supplement or amendment at such time would interfere with such transaction or purpose. Parent shall promptly give the holders of Earnout Shares written notice of such postponement containing a general statement of the reasons for such postponement and an approximation of the anticipated delay. Upon receipt by a holder of Earnout Shares of notice of an event of the kind described in this Section 3.8, such holder shall forthwith discontinue such holder's disposition of Earnout Shares until such holder's receipt of notice from Parent that such disposition may continue and of any supplemented or amended prospectus indicated in such notice. Parent shall use its reasonable efforts to permit sales of Earnout Shares on such shelf registration statement for at least 180 days during any 360-day period. ARTICLE IV Retention of Assets 4.1 Assets Retained by IDX. Notwithstanding anything in this Agreement to the contrary, it is specifically understood and agreed that the assets of ChannelHealth identified on Schedule 4.1 hereto shall be assigned, sold, conveyed, transferred and delivered by ChannelHealth to IDX on or before the Closing Date as contemplated by the ChannelHealth/IDX Asset Purchase Agreement and shall not be included in the properties or assets of ChannelHealth acquired by Parent through the ChannelHealth Merger (the "Retained Assets"). 14

ARTICLE V Accrued Liabilities Adjustment 5.1 Adjustment to ChannelHealth Cash Reserves. (a) As soon as practicable following the Closing Date and in any event within 60 days of the Closing Date, Parent shall cause the ChannelHealth Surviving Corporation to prepare and deliver to Parent and the Stockholders' Representative a balance sheet of ChannelHealth as at the close of business on the Closing Date (the "Closing Date Balance Sheet"). The Closing Date Balance Sheet shall be audited and certified by Ernst & Young LLP, ChannelHealth's regular independent certified public accountants ("ChannelHealth's Accountants"), shall be based upon the books and records of ChannelHealth, shall be prepared in accordance with GAAP applied on a basis consistent with that of the preceding fiscal year, and shall present fairly the financial position of ChannelHealth as at the Closing Date. All accruals as at the Closing Date which, in accordance with GAAP applied on a basis consistent with ChannelHealth's practice of the preceding fiscal year, should be reflected on a balance sheet, shall be reflected on the Closing Date Balance Sheet, including, without limitation, with respect to such items as employee bonuses, profit- sharing plan contributions and promotional expenses. Allscripts's regular independent public accountants, PricewaterhouseCoopers LLP ("Allscripts's Accountants") and the Stockholders' Representative's regular independent public accountants, Ernst & Young LLP (the "Stockholders' Representative's Accountants"), shall each have the opportunity to observe the taking of inventories in connection with the preparation of the Closing Date Balance Sheet, to consult with and to examine the work papers, schedules and other documents prepared or reviewed by ChannelHealth's Accountants in connection with the preparation of their report and of the Accrued Liabilities Certificate referred to in Section 5.1(b). (b) "Accrued Liabilities" shall be the accounts payable, other current liabilities and accrued liabilities of ChannelHealth as reflected on the Closing Date Balance Sheet; provided, however, the Closing Date Balance Sheet shall not include accrued liabilities relating to Taxes for which IDX is indemnifying Allscripts pursuant to Article XI. The calculation of Accrued Liabilities shall be made by ChannelHealth's Accountants, who shall render a certificate (the "Accrued Liabilities Certificate") showing such calculation and stating that such calculation has been made in accordance with the provisions of this Article V.

(a) In the event that any Legal Proceedings shall be instituted or that any claim or demand ("Claim") shall be asserted by any Person in respect of which payment may be sought under Section 11.1 hereof, the indemnified party shall reasonably and promptly cause written notice of the assertion of any Claim of which it has knowledge which is covered by this indemnity to be forwarded to the indemnifying party. The indemnifying party shall have the right, at its sole option and expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the indemnified party, and to defend against, negotiate, settle or otherwise deal with any Claim which relates to any Losses indemnified against hereunder. If the indemnifying party elects to defend against, negotiate, settle or otherwise deal with any Claim which relates to any Losses indemnified against hereunder, it shall within five days (or sooner, if the nature of the Claim so requires) notify the indemnified party of its intent to do so. If the indemnifying party elects not to defend against, negotiate, settle or otherwise deal with any Claim which relates to any Losses indemnified against hereunder, fails to notify the indemnified party of its election as herein provided or contests its obligation to indemnify the indemnified party for such Losses under this Agreement, the indemnified party may defend against, negotiate, settle or otherwise deal with such Claim. If the indemnified party defends any Claim, then the indemnifying party shall reimburse the indemnified party for the Expenses of defending such Claim upon submission of periodic bills. If the indemnifying party shall assume the defense of any Claim, the indemnified party may participate, at his or its own expense, in the defense of such Claim; provided, however, that such indemnified party shall be entitled to participate in any such defense with separate counsel at the expense of the 44

indemnifying party if, so requested by the indemnifying party to participate or (ii) in the reasonable opinion of counsel to the indemnified party, a conflict or potential conflict exists between the indemnified party and the indemnifying party that would make such separate representation advisable; and provided, further, that the indemnifying party shall not be required to pay for more than one such counsel for all indemnified parties in connection with any Claim. The parties hereto agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such Claim. The indemnified party shall not agree to such settlement of any such Legal Proceeding or Claim without the prior written consent of the indemnifying party. The indemnifying party shall have full discretion to agree to any settlement of any such Legal Proceeding or Claim; provided, however, that the indemnifying party may not agree to any settlement of such Legal Proceeding or Claim that does not include a release of the indemnified party from all liability with respect thereto without the prior written consent of the indemnified party, which consent shall not be unreasonably withheld or delayed. (b) After any final judgment or award shall have been rendered by a court, arbitration board or administrative agency of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement shall have been consummated, or the indemnified party and the indemnifying party shall have arrived at a mutually binding agreement with respect to a Claim hereunder, the indemnified party shall forward to the indemnifying party notice of any sums due and owing by the indemnifying party pursuant to this Agreement with respect to such matter and the indemnifying party shall be required to pay all of the sums so due and owing to the indemnified party by wire transfer of immediately available funds within 10 business days after the date of such notice. (c) Notwithstanding the foregoing, IDX shall continue to defend the Claim comprising the ChannelHealth Litigation until such Claim is disposed of as described in Section 11.2(b). (d) The failure of the indemnified party to give reasonably prompt notice of any Claim shall not release, waive or otherwise affect the indemnifying party's obligations with respect thereto except to the extent that the indemnifying party can demonstrate actual loss and prejudice as a result of such failure. 11.3 Tax Matters. (a) Tax Indemnification. IDX agrees to be responsible for and to indemnify and hold the Allscripts Indemnified Parties harmless from and against any and all Taxes that may be imposed upon or assessed against ChannelHealth or the assets thereof: (A) with respect to all taxable periods ending on or prior to the Closing Date; (B) with respect to any and all Taxes of ChannelHealth for the period allocated to IDX pursuant to Section 11.3(b)(iv); (C) arising by reason of any breach by ChannelHealth or any inaccuracy of any of the representations contained in Section 6.10 hereof; (D) by reason of being a successor-in-interest or transferee of another entity; (E) with respect to any and all Taxes of any member of a consolidated, combined or unitary group of which ChannelHealth (or any predecessor) is or was a member on or prior to the Closing Date, by reason of the liability of ChannelHealth pursuant to Treasury Regulation Section 1.1502-6(a) or any analogous or similar state, local or foreign Law or regulation; and (F) by reason of the transactions contemplated by Article IV hereof. IDX shall also pay and shall indemnify and hold harmless the Allscripts Indemnified Parties from and against any losses, damages, liabilities, obligations, deficiencies, costs and expenses (including, without limitation, reasonable expenses and fees for attorneys and accountants) ("Related Costs") incurred in connection with the Taxes for which IDX is responsible to indemnify the Allscripts Indemnified Parties pursuant to this Section 11.3(a) (or any asserted deficiency, claim, demand, action, suit, proceeding, judgment or assessment, including the defense or settlement thereof, relating to such Taxes) or the enforcement of this Section 11.3(a). 45

(b) Preparation of Tax Returns; Payment of Taxes. (i) IDX shall (A) include ChannelHealth and (where applicable) any of its Subsidiaries in (1) the U.S. consolidated federal income Tax Returns of IDX required to be filed after the date hereof for all taxable periods ending on or before the Closing Date and (2) where applicable, all combined consolidated or unitary Tax Returns that are required to be filed by IDX for any taxable period ending on or before the Closing Date and (B) cause ChannelHealth to file all Tax Returns required to be filed by ChannelHealth on or prior to the Closing Date. IDX shall pay any and all Taxes due with respect to such Tax Returns. All Tax Returns described in this Section 11.3(b)(i) shall be prepared in a manner consistent with prior practice unless a past practice has been finally determined to be incorrect by the applicable taxing authority or a contrary treatment is required by applicable tax Laws (or judicial or administrative interpretations thereof). IDX shall cause ChannelHealth to provide Allscripts with copies of such completed Tax Returns at least 10 days prior to the filing date, and Allscripts shall be provided an opportunity to review such Tax Returns and supporting workpapers and Schedules prior to the filing of such Tax Returns. The failure of Allscripts to propose any changes to any such Tax Return within such 10 days shall be deemed to be an indication of its approval thereof. IDX and Allscripts shall attempt in good faith mutually to resolve any disagreements regarding such Tax Returns prior to the due date for filing thereof. Any disagreements regarding such Tax Returns which are not resolved prior to the filing thereof shall be promptly resolved pursuant to Section 11.3(f) which shall be binding on the parties. (ii) Following the Closing, Allscripts shall be responsible for preparing or causing to be prepared all federal, foreign, state and local Tax Returns required to be filed by ChannelHealth after the Closing Date. (iii) Not later than five days before the due date for payment of Taxes with respect to any Tax Returns which Allscripts has the responsibility to file, IDX shall pay to Allscripts an amount equal to that portion of the Taxes shown on such return for which IDX has an obligation to indemnify Allscripts and its Affiliates pursuant to the provisions of Section 11.3(a). (iv) For federal income Tax purposes, the taxable year of ChannelHealth shall end as of the close of the Closing Date and, with respect to all other Taxes, IDX and Allscripts will, unless prohibited by applicable law, close the taxable period of ChannelHealth as of the close of the Closing Date. Neither IDX nor Allscripts shall take any position inconsistent with the preceding sentence on any Tax Return. In any case where applicable law does not permit ChannelHealth to close its taxable year on the Closing Date or in any case in which a Tax is assessed with respect to a taxable period which includes the Closing Date (but does not begin or end on that day), then Taxes, if any, attributable to the taxable period of ChannelHealth beginning before and ending after the Closing Date shall be allocated (i) to IDX for the period up to and including the Closing Date, and (ii) to Allscripts for the period subsequent to the Closing Date. Any allocation of income or deductions required to determine any Taxes attributable to any period beginning before and ending after the Closing Date shall be prepared by Allscripts and shall be made by means of a closing of the books and records of ChannelHealth as of the close of the Closing Date, provided that exemptions, allowances or deductions that are calculated on an annual basis (including, but not limited to, depreciation and amortization deductions) shall be allocated between the period ending on the Closing Date and the period after the Closing Date in proportion to the number of days in each such period. Allscripts shall provide IDX with a schedule showing the computation of the allocation at least 30 days prior to the due date for filing a Tax Return which includes the Closing Date. IDX shall have the right to review such schedule, and Allscripts and IDX shall attempt in good faith mutually to resolve any disagreements regarding the determination of such allocation. Any disagreements regarding such determination shall be resolved pursuant to Section 11.3(f). Any amount owing from IDX under this Section 11.3(b)(iv) shall be paid no later than five days prior to the filing of the underlying Tax Return. (v) With respect to any Tax Returns required to be filed by Allscripts with respect to any taxable period of ChannelHealth ending on or before the Closing Date, Allscripts shall provide IDX with a copy of such completed Tax Returns at least 10 days prior to the due date for filing of such Tax Returns. IDX shall have the right to review such Tax Returns, and Allscripts and IDX shall attempt in good faith 46

mutually to resolve any disagreements regarding the preparation thereof prior to filing thereof. The failure of IDX to propose any changes to any such Tax Return within such 10 days shall be deemed to be an indication of its approval thereof. Any disagreements regarding such determination shall be resolved pursuant to Section 11.3(f). If such disagreement cannot be resolved prior to the due date for filing such Tax Return, Allscripts may cause such Tax Return to be filed in the manner proposed by Allscripts, without prejudice to IDX's right to pursue a final resolution of such disagreement. Any amount owing from IDX under this Section 11.3(b)(v) shall be paid no later than five days prior to the filing of the underlying Tax Return. (c) Cooperation with Respect to Tax Returns. Allscripts and IDX agree to furnish or cause to be furnished to each other, and each at their own expense, as promptly as practicable, such information (including access to books and records) and assistance, including making employees available on a mutually convenient basis to provide additional information and explanations of any material provided, relating to ChannelHealth as is reasonably necessary for the filing of any Tax Return, for the preparation for any audit, and for the prosecution or defense of any claim, suit or proceeding relating to any adjustment or proposed adjustment with respect to Taxes. Allscripts or ChannelHealth shall retain in its possession, and shall provide IDX reasonable access to (including the right to make copies of), such supporting books and records and any other materials that IDX may specify with respect to Tax matters relating to any taxable period ending on or prior to the Closing Date until the relevant statute of limitations has expired. After such time, Allscripts may dispose of such material, provided that prior to such disposition Allscripts shall give IDX a reasonable opportunity to take possession of such materials. (d) Carrybacks. IDX shall pay to Allscripts the amount of any Tax benefit (including interest thereon) realized by IDX or any Affiliate thereof as a result of the carryback of any Tax loss, deduction or credit of ChannelHealth from any taxable period beginning after the Closing Date to a taxable period ending on or before the Closing Date. IDX shall pay such amount to Allscripts within 10 business days after such Tax benefit is realized by IDX or any Affiliate of it as a refund or otherwise, provided that Allscripts shall return to IDX the amount, if any, by which the amount of such Tax benefit is thereafter reduced pursuant to a final determination. (e) Transfer Taxes. IDX shall be liable for and shall pay (and shall indemnify and hold harmless Allscripts against) all sales, use, stamp, documentary, filing, recording, transfer or similar fees or Taxes or governmental charges (including, without limitation, real property transfer gains Taxes, UCC-3 filing fees, FAA, ICC, DOT, real estate and motor vehicle registration, title recording or filing fees and other amounts payable in respect of transfer filings) as levied by any taxing authority or governmental agency in connection with the transactions contemplated by this Agreement (other than Taxes measured by or with respect to income imposed on Allscripts or its Affiliates). IDX hereby agree to file all necessary Documents (including, but not limited to, all Tax Returns) with respect to all such amounts in a timely manner. (f) Dispute Resolution. Any dispute as to any matter covered hereby shall be resolved by an independent accounting firm mutually acceptable to IDX and Allscripts. The fees and expenses of such accounting firm shall be borne equally by IDX and Allscripts. (g) Sole Remedy. The indemnification provided for in this Section 11.3 shall be the sole remedy for any claim in respect of Taxes and the provisions of Sections 11.1 through 11.2 hereof shall not apply to such claims. (h) Survival. Any claim for indemnity under this Section 11.3 may be made at any time prior to 60 days after the expiration of the applicable Tax statute of limitations with respect to the relevant taxable period (including all periods of extension, whether automatic of permissive). (i) Certain Representations. Each of Parent and Allscripts has no present intention to merge or liquidate Parent or Allscripts with or into another Person or transfer any of the assets thereof other than in the ordinary 47

course of business or, in the case of Allscripts, other than pursuant to a transaction described in Section 368(a)(2)(C) of the Code or Treasury Regulation Sections 1.368-2(f) or 1.368-2(k). As of the date of consummation of the Mergers, Parent and Allscripts have no plan or intention to engage in a transaction that (i) would be an Integrated Transaction (as defined in Section 8.20 hereof) and (ii) would cause the stockholders of Allscripts and the ChannelHealth Stockholders immediately before the Mergers and any Integrated Transferors (as defined in Section 8.20 hereof) not to be in control (within the meaning of Section 368(c) of the Code) of Parent immediately after the Mergers. (j) Plan of Reorganization This Agreement and the transactions contemplated hereby are intended to constitute a "plan of reorganization" within the meaning of Treasury Regulation Section 1.368-2(g). Following the Closing Date, Parent and IDX shall report and otherwise treat for Tax purposes the exchange of ChannelHealth Stock for Parent Common Stock under Section 351 of the Code. 11.4 Employee Benefits and Labor Indemnity. IDX hereby agrees to indemnify and hold the Allscripts Indemnified Parties harmless from and against any and all Losses, if any, (i) arising out of or based upon or with respect to any Employee Benefit Plan or Pension Plan or any other "employee benefit plan" within the meaning of Section 3(3) of ERISA maintained by, contributed to or to which there is or was an obligation to contribute to by IDX, ChannelHealth or any ERISA Affiliate and (ii) as a result of any Claim made with respect to employment prior to or on the Closing Date with ChannelHealth including, without limitation, any Claim with respect to, relating to arising out of or in connection with discrimination by ChannelHealth or wrongful discharge (including constructive discharge) prior to the Closing Date. 11.5 Tax Treatment of Indemnity Payments. IDX and Allscripts agree to treat any indemnity payment made pursuant to this Article XI as an adjustment to the consideration paid hereunder for federal, state, local and foreign income Tax purposes. If any indemnification payment under Article XI (including, without limitation, this Section 11.5) is determined to be taxable to Allscripts or ChannelHealth by any taxing authority, IDX shall also indemnify Allscripts or ChannelHealth for any Taxes incurred by reason of the receipt of such payment and any Related Costs incurred by Allscripts or ChannelHealth in connection with such Taxes (or any asserted deficiency, claim, demand, action, suit, proceeding, judgment or assessment, including the defense or settlement thereof, relating to such Taxes). 11.6 Limitations. (a) Except with respect to Claims based on actual fraud, the rights of the Indemnified Parties under this Article XI shall be the sole and exclusive remedies of the Indemnified Parties and their respective Affiliates with respect to Claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement contained in this Agreement or otherwise relating to the transactions that are the subject of this Agreement. Without limiting the generality of the foregoing sentence, in no event shall any party hereto, nor its successors or permitted assigns be entitled to claim or seek rescission of the transactions consummated under this Agreement. (b) Notwithstanding anything to the contrary contained in this Agreement, each of the following three limitations shall apply: (i) the aggregate liability of IDX for the sum of all Losses under Sections 11.1(a)(i), (iii), (v), (vi) and (vii) (insofar as the Expenses referred to therein relate to Losses arising under Sections 11.1(a)(i), (iii), (v) or (vi)) and clause (ii) of Section 11.4 shall not exceed $50 million; (ii) the aggregate liability of Allscripts for the sum of all Losses under Sections 11.1(b)(ii) (excluding Losses arising from a breach of Section 11.3(i)), (iii) and (v) (insofar as the Expenses referred to therein relate to Losses arising under Sections 11.1(b)(ii) or (iii)) shall not exceed $50 million; provided, however, any issuance of Earnout Shares shall not be counted against such amount; and (iii) IDX shall not be liable for any individual Loss under Sections 11.1(a)(i), (iii), (v), (vi) or (vii) (insofar as the Expenses referred to therein relate to Losses arising under Sections 11.1(a)(i), (iii), (v) or 48

(vi)) and clause (ii) of Section 11.4 unless such Loss exceeds $50,000 and IDX shall not be liable for any such individual Losses in excess of $50,000 unless and until the aggregate amount of such individual Losses in excess of $50,000 exceeds $1 million (it being understood that in such case IDX shall be liable only for the amount of such Losses in excess of $500,000). (c) In no event shall any Indemnifying Party be responsible and liable for any Losses or other amounts under this Article XI that are consequential, in the nature of lost profits, diminution in value, damage to reputation or the like, special or punitive or otherwise not actual Losses. Allscripts shall (and shall cause the ChannelHealth Surviving Corporation to) use commercially reasonable efforts to pursue all legal rights and remedies available in order to minimize the Losses for which indemnification is provided to Allscripts by IDX under Article XI. (d) The amount of any Losses for which indemnification is provided under this Article XI shall be reduced by any related recoveries to which the Indemnified Party is entitled under insurance policies or other related payments received or receivable from third parties and any tax benefits actually received by the Indemnified Party or any of its Affiliates or for which the Indemnified Party or any of its Affiliates is eligible on account of the matter resulting in such Losses or the payment of such Losses. (e) Notwithstanding anything to the contrary in this Agreement, the amount of any Losses for which indemnification by IDX is provided under this Article XI shall be calculated net of any accruals, reserves or provisions reflected in the Closing Date Balance Sheet. (f) Effective as of the Effective Time, each of Parent and Allscripts hereby waives and releases (and shall cause the ChannelHealth Surviving Corporation to waive and release), any claim ChannelHealth may have against IDX, except (i) any claims or rights hereunder or under any Ancillary Agreement and (ii) any claims or rights under the ChannelHealth/IDX Asset Purchase Agreement. Effective as of the Effective Time, IDX hereby waives and releases any claim IDX may have against the ChannelHealth Surviving Corporation, except any claims or rights hereunder or under any Ancillary Agreement. 11.7 Acknowledgement by Allscripts.

ANNEX B PERSONAL AND CONFIDENTIAL July 13, 2000 Board of Directors Allscripts, Inc. 2401 Commerce Drive Libertyville, IL 60048 Gentlemen: You have requested our opinion as to the fairness from a financial point of view to Allscripts, Inc. ("Allscripts") of the ChannelHealth Common Stock Merger Consideration (as defined below) to be paid by Allscripts pursuant to the Agreement and Plan of Merger (the "Agreement"), dated as of July 13, 2000, among Allscripts Holding, Inc., a wholly-owned subsidiary of Allscripts ("Parent"), Allscripts, Bursar Acquisition, Inc., a wholly-owned subsidiary of Parent ("SubA"), Bursar Acquisition No.2, Inc., a wholly-owned subsidiary of Parent ("SubB"), IDX Systems Corporation ("IDX") and ChannelHealth Incorporated, a corporation owned 88.49% by IDX ("ChannelHealth"). Pursuant to the Agreement, (i)(a) SubA will merge with and into Allscripts, (b) each share of common stock, par value $0.01 per share ("Allscripts Shares"), of Allscripts (other than Allscripts Shares to be canceled pursuant to section 2.1(a) of the Agreement) will be converted into the right to receive one (1) share of common stock, par value $0.01 ("Parent Shares"), of Parent, and (c) Allscripts will become a wholly-owned subsidiary of Parent, and (ii)(a) SubB will merge with and into ChannelHealth (the "ChannelHealth Merger"), and (b) each share of common stock, par value $0.001 per share (the "ChannelHealth Common Stock"), of ChannelHealth (other than shares of ChannelHealth Common Stock to be canceled pursuant to Section 2.2 of the Agreement and ChannelHealth Dissenting Shares (as defined in the Agreement)) will be converted into the right to receive 0.33730 Parent Shares (the "ChannelHealth Common Stock Merger Consideration"). Additionally, pursuant to the Agreement, each share of Series A Convertible Preferred Stock, $0.001 par value per share (the "ChannelHealth Preferred Stock"), of ChannelHealth (other than shares of ChannelHealth Preferred Stock to be canceled pursuant to Section 2.2 of the Agreement) will be converted into the right to receive 0.33730 Parent Shares. Section 3.1 of the Agreement also provides that, if certain financial milestones are achieved in the future, Parent will issue and deliver additional Parent Shares for the benefit of the holders of ChannelHealth Common Stock and the holders of ChannelHealth Preferred Stock. Goldman, Sachs & Co., as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. We are familiar with Allscripts having provided certain investment banking services to Allscripts from time to time, including having acted as managing underwriter of the initial public offering of Allscripts Shares on July 23, 1999 and having acted as managing underwriter of the public offering of Allscripts Shares on March 6, 2000. In addition, we have acted as Allscripts' financial advisor in connection with, and have participated in certain of the negotiations leading to, the Agreement. In addition, we may provide investment banking services to IDX in the future. Goldman, Sachs & Co. provides a full range of financial advisory and securities services and, in the course of its normal trading activities, may from time to time effect transactions and hold securities, including derivative securities, of Allscripts or IDX for its own account and for the accounts of customers. In connection with this opinion, we have reviewed, among other things, the Agreement; the Strategic Alliance Agreement, in the form of Exhibit D to the Agreement; the Stock Rights and Restrictions Agreement, in the form of Exhibit E to the Agreement; the Registration Statements on Form S-1 of Allscripts including the Prospectuses therein dated July 23, 1999 and March 6, 2000; Annual Reports to Stockholders and Annual Reports on Form 10-K of Allscripts for the year ended December 31, 1999 and Annual Reports to Stockholders and Annual Reports on Form 10-K of IDX for the five years ended December 31, 1999; certain interim reports

to stockholders and Quarterly Reports on Form 10-Q of Allscripts and IDX; certain other communications from Allscripts and IDX to their respective stockholders; certain internal financial analysis and forecasts for ChannelHealth prepared by the management of ChannelHealth and adjusted by the management of Allscripts; certain internal financial analyses and forecasts for Allscripts prepared by the management of Allscripts; and certain cost savings and operating synergies projected by the management of Allscripts to result from the transactions contemplated by the Agreement, including the Strategic Alliance Agreement (the "Synergies"). We also have held discussions with members of the senior management of Allscripts and ChannelHealth regarding their assessment of the strategic rationale for, and the potential benefits of, the transactions contemplated by the Agreement and their past and current business operations, financial condition and future prospects. In addition, we have reviewed the reported price and trading activity for the Allscripts Shares, compared certain financial and stock market information for Allscripts and certain financial information for ChannelHealth with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the healthcare information technology industry specifically and in other industries generally and performed such other studies and analyses as we considered appropriate. We have relied upon the accuracy and completeness of all of the financial and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the forecasts for Allscripts and ChannelHealth and the Synergies have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of Allscripts, and that the Synergies will be realized in the amounts and the time periods contemplated thereby. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities of Allscripts, ChannelHealth, IDX or any of their subsidiaries and we have not been furnished with any such evaluation or appraisal. We have also assumed that the Strategic Alliance Agreement and the Stock Rights and Restrictions Agreement will be executed in the forms attached as Exhibit D and Exhibit E to the Agreement, respectively. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of Allscripts in connection with its consideration of the transactions contemplated by the Agreement and such opinion does not constitute a recommendation as to how any holder of Allscripts Shares should vote with respect to such transactions. Based upon and subject to the foregoing and based upon such other matters as we consider relevant, it is our opinion that as of the date hereof the ChannelHealth Common Stock Merger Consideration to be paid by Allscripts pursuant to the Agreement is fair from a financial point of view to Allscripts. 2

ANNEX C DELAWARE GENERAL CORPORATION LAW SECTION 262 -- APPRAISAL RIGHTS 262 APPRAISAL RIGHTS. (a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to sec.228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository. (b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to sec.251 (other than a merger effected pursuant to sec.251 (g) of this title), sec.252, sec.254, sec.257, sec.258, sec.263 or sec.264 of this title: (1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of sec.251 of this title. (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to Sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except: a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof; b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders; c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph. (3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under sec.253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable. (d) Appraisal rights shall be perfected as follows: (1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsections (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or (2) If the merger or consolidation was approved pursuant to sec.228 or sec.253 of this title, each constituent corporation, either before the effective date of the merger or consolidation or within ten days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section; provided that, if the notice is given on or after the effective date of the merger or consolidation, such notice shall be given by the surviving or resulting corporation to all such holders of any class or series of stock of a constituent corporation that are entitled to appraisal rights. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given. 2

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later. (f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by one or more publications at least one week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation. (g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. (h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section. (i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of 3

uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state. (j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal. (k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just. (l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation. 4

PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 20. Indemnification of Directors and Officers Section 102(b) of the Delaware General Corporation Law ("DGCL") allows a corporation to include in its certificate of incorporation a provision to eliminate or limit the personal liability of a director to the registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except in cases where the director breached his or her duty of loyalty to the registrant or its stockholders, failed to act in good faith, engaged in intentional misconduct or a knowing violation of a law, willfully or negligently authorized the unlawful payment of a dividend or approved an illegal stock repurchase (as provided in Section 174 of the DGCL) or derived an improper personal benefit. The registrant's certificate of incorporation, as amended, contains provisions that eliminate directors' personal liability, in certain circumstances, as set forth below. The registrant's certificate of incorporation, as amended, provides that a director will not be personally liable to the registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit. The registrant's certificate of incorporation, as amended, provides that each person who has been or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a "proceeding"), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the registrant, or is or was serving at the request of the registrant as a director, officer, employee or agent of another corporation, partnership joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the registrant to the fullest extent authorized by the DGCL, or any other applicable law, as the same exists or may hereafter be amended (but, in case of any such amendment, only to the extent that such amendment permits the registrant to provide broader indemnification rights than said law permitted the registrant to provide prior to such amendment), against all expense, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators. The registrant has a duty to indemnify any person seeking indemnification pursuant to the registrant's certificate of incorporation in connection with a proceeding (or part thereof) initiated by that person only if the proceeding (or part thereof) was authorized by the board of directors of the registrant. The registrant may, by action of its board of directors, provide indemnification to employees or agents of the registrant to the fullest extent of the foregoing indemnification of directors and officers. The registrant may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the registrant or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the registrant would have the power to indemnify such person against expense, liability or loss under the DGCL, or any other applicable law.

Item 22. Undertakings. (a) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (b) (1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by other items of the applicable form. (2) The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. (d) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. (e) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

THIRD: The nature of the business and the objects and purposes to be conducted or promoted by the Corporation are to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware. FOURTH: 1. Authorized Shares. The total number of shares of stock of all classes which the Corporation shall have authority to issue is seventy-six million (76,000,000), of which one million (1,000,000) shall be shares of Preferred Stock with a par value of $0.01 per share ("Preferred Stock"), and seventy-five million (75,000,000) shall be shares of Common Stock with a par value of $0.01 per share ("Common Stock"). 2. Preferred Stock. (a) The Preferred Stock shall be issuable in series, and in connection with the issuance of any series of Preferred Stock and to the extent now or hereafter permitted by the laws of the State of Delaware, the Board of Directors is authorized to fix by resolution the designation of each series, the stated value of the shares of each series, the dividend rate or rates of each series (which rate or rates may be expressed in terms of a formula or other method by which such rate or rates shall be calculated from time to time) and the date or dates and other provisions respecting the payment of dividends, the provisions, if any, for a sinking fund for the shares of each series, the preferences of the shares of each series in the event of the liquidation or dissolution of the Corporation, the provisions, if any, respecting the redemption of the shares of each series and, subject to requirements of the laws of the State of Delaware, the voting rights (except that such shares shall not have more than one vote per share), the terms, if any, upon which the shares of each series shall be convertible into or exchangeable for any other shares of

stock of the Corporation and any other relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, of the shares of each series. (b) Preferred Stock of any series redeemed, converted, exchanged, purchased, or otherwise acquired by the Corporation shall constitute authorized but unissued Preferred Stock. (c) All shares of any series of Preferred Stock, as between themselves, shall rank equally and be identical (except that such shares may have different dividend provisions); and all series of Preferred Stock, as between themselves, shall rank equally and be identical except as set forth in resolutions of the Board of Directors authorizing the issuance of such series. 3. Common Stock. (a) After dividends to which the holders of Preferred Stock may then be entitled under the resolutions creating any series thereof have been declared and after the Corporation shall have set apart the amounts required pursuant to such resolutions for the purchase or redemption of any series of Preferred Stock, the holders of Common Stock shall be entitled to have dividends declared in cash, property, or other securities of the Corporation out of any net profits or net assets of the Corporation legally available therefor, if, as and when such dividends are declared by the Corporation's Board of Directors. (b) In the event of the liquidation or dissolution of the Corporation's business and after the holders of Preferred Stock shall have received amounts to which they are entitled under the resolutions creating such series, the holders of Common Stock shall be entitled to receive ratably the balance of the Corporation's net assets available for distribution. (c) Each share of Common Stock shall be entitled to one vote upon all matters upon which stockholders have the right to vote, but shall not be entitled to vote for the election of any directors who may be elected by vote of the Preferred Stock voting as a class if so provided in the resolution creating such Preferred Stock pursuant to Section 2(a) of this Article FOURTH. 4. Preemptive Rights. No holder of any shares of the Corporation shall have any preemptive right to subscribe for or to acquire any additional shares of the Corporation of the same or of any other class whether now or hereafter authorized or any options or warrants giving the right to purchase any such shares, or any bonds, notes, debentures or other obligations convertible into any such shares. FIFTH: The Corporation is to have perpetual existence. SIXTH: The private property of the stockholders shall not be subject to the payment of corporate debts to any extent whatever. SEVENTH: Except as may otherwise be fixed by resolution of the Board of Directors pursuant to the provisions of Article FOURTH hereof relating to the rights of the holders of Preferred Stock to elect directors as a class, the number of directors of the Corporation shall be 2

fixed from time to time by or pursuant to the By-Laws of the Corporation. The directors, other than those who may be elected by the holders of Preferred Stock, shall be classified, with respect to the time for which they severally hold office, into three classes, as nearly equal in number as possible. The first class shall be initially elected for a term expiring at the next ensuing annual meeting, the second class shall be initially elected for a term expiring one year thereafter, and the third class shall be elected for a term expiring two years thereafter, with each member of each class to hold office until his successor is elected and qualified. At each annual meeting of the stockholders of the Corporation held after the initial classification and election of directors, the successors of the class of directors whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election. Advance notice of stockholder nominations for the election of directors shall be given in the manner provided in the By-Laws of the Corporation. Except as may otherwise be fixed by resolution of the Board of Directors pursuant to the provisions of Article FOURTH hereof relating to the rights of the holders of Preferred Stock to elect directors as a class, newly created directorships resulting from any increase in the number of directors and any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or any other cause shall be filled by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors. Any director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the class of directors in which the new directorship was created (subject to the requirements of this Article SEVENTH that all classes be as nearly equal in number as possible) or in which the vacancy occurred and until such director's successor shall have been elected and qualified. No decrease in the number of directors constituting the Board of Directors shall shorten the term of an incumbent director. Subject to any rights of the holders of Preferred Stock to elect directors as a class, a director may be removed only for cause and only by the affirmative vote of the holders of 80% of the combined voting power of the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized: 1. To adopt, amend and repeal the By-Laws of the Corporation. Any ByLaws adopted by the directors under the powers conferred hereby may be amended or repealed by the directors or by the stockholders. Notwithstanding the foregoing or any other provision in this Certificate of Incorporation or the By-Laws of the Corporation to the contrary, Article 11, Sections 3 and 7 and Article 111, Sections 1, 2 and 3 of the ByLaws shall not be amended or repealed and no provision inconsistent therewith shall be adopted without the affirmative vote of the holders of at least 80% of the voting power of all the shares of the Corporation entitled to vote generally in the election of directors, voting together as a single class. 3

2. To fix and determine, and to vary the amount of, the working capital of the Corporation, and to determine the use or investment of any assets of the Corporation, to set apart out of any of the funds of the Corporation available for dividends a reserve or reserves for any proper purpose and to abolish any such reserve or reserves. 3. To authorize the purchase or other acquisition of shares of stock of the Corporation or any of its bonds, debentures, notes, scrip, warrants or other securities or evidence of indebtedness. 4. Except as otherwise provided by law, to determine the places within or without the State of Delaware, where any or all of the books of the Corporation shall be kept. 5. To authorize the sale, lease or other disposition of any part or parts of the properties of the Corporation and to cease to conduct the business connected therewith or again to resume the same, as it may deem best. 6. To authorize the borrowing of money, the issuance of bonds, debentures and other obligations or evidences of indebtedness of the Corporation, secured or unsecured, and the inclusion of provisions as to redeemability and convertibility into shares of stock of the Corporation or otherwise; and the mortgaging or pledging, as security for money borrowed or bonds, notes, debentures or other obligations issued by the Corporation, of any property of the Corporation, real or personal, then owned or thereafter acquired by the Corporation. 7. To authorize the negotiation and execution on behalf of the Corporation of agreements with officers and other employees of the corporation relating to the payment of severance compensation to such officers or employees. In addition to the powers and authorities herein or by statute expressly conferred upon it, the Board of Directors may exercise all such powers and do all such acts and things as may be exercised or done by the Corporation, subject, nevertheless, to the provisions of the laws of the State of Delaware, of this Certificate of Incorporation and of the By-Laws of the Corporation. Subject to any limitation in the By-Laws, the members of the Board of Directors shall be entitled to reasonable fees, salaries, or other compensation for their services, as determined from time to time by the Board of Directors, and to reimbursement for their expenses as such members. Nothing herein contained shall preclude any director from serving the Corporation or its subsidiaries or affiliates in any other capacity and receiving compensation therefor. Notwithstanding anything contained in this Amended and Restated Certificate of Incorporation to the contrary, the affirmative vote of the holders of at least 80% of the voting power of all shares of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend, adopt any provision inconsistent with or repeal this Article SEVENTH. EIGHTH: Both stockholders and directors shall have power, if the By-Laws so provide, to hold their meetings and to have one or more offices within or without the State of Delaware. 4

Except as may otherwise be fixed by resolution of the Board of Directors pursuant to the provisions of Article FOURTH hereof relating to the rights of the holders of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation may be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders. Except as otherwise required by law and subject to the rights of the holders of Preferred Stock, special meetings of stockholders may be called only by the Chairman, if any, on his own initiative, the President on his own initiative or by the Board of Directors pursuant to a resolution approved by a majority of the entire Board of Directors. Notwithstanding anything contained in this Amended and Restated Certificate of Incorporation to the contrary, the affirmative vote of the holders of at least 80% of the voting power of all shares of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend, adopt any provision inconsistent with or repeal this Article EIGHTH. NINTH: Except as otherwise provided in this Amended and Restated Certificate of Incorporation, the Corporation reserves the right to amend, alter, change or repeal any provision contained in this Amended and Restated Certificate of Incorporation in the manner now or hereafter prescribed by statute, and all rights conferred upon stockholders herein are granted subject to this reservation. TENTH: (a) A director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law of the State of Delaware or (iv) for any transaction from which the director derived an improper personal benefit. If the General Corporation Law of the State of Delaware, or any other applicable law, is amended to authorize corporation action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of the State of Delaware, or any other applicable law, as so amended. Any repeal or modification of this Section (a) by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification. (b) (1) Each person who has been or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a "proceeding"), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is an alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the General Corporation Law of the State of Delaware, or any other applicable law, as the same exists or may hereafter be 5

amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all expenses, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that except as provided in paragraph (2) of this Section (b) with respect to proceedings seeking to enforce rights to indemnification, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation. The right to indemnification conferred in this Section (b) shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that if the General Corporation Law of the State of Delaware, or any other applicable law, requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding shall be made only upon delivery to the Corporation of an undertaking by or on behalf of such director or officer to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section (b) or otherwise. (2) If a claim under paragraph (1) of this Section (b) is not paid in full by the Corporation within thirty days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standard of conduct which make it permissible under the General Corporation Law of the State of Delaware, or any other applicable law, for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, stockholders or independent legal counsel) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the General Corporation Law of the State of Delaware, or any other applicable law, nor an actual determination by the Corporation (including its Board of Directors, stockholders or independent legal counsel) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct. (3) The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Section (b) shall not be exclusive of any other right which any person may have or hereafter acquire under any 6

statute, provision of this Certificate of Incorporation, By-Law, agreement, vote of stockholders or disinterested directors or otherwise. (4) The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the General Corporation Law of the State of Delaware, or any other applicable law. (5) The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification, and rights to be paid by the Corporation the expenses incurred in defending any proceeding in advance of its final disposition, to any employee or agent of the Corporation to the fullest extent of the provisions of this Section (b) with respect to the indemnification and advancement of expenses of directors and officers of the Corporation. (6) Any repeal or modification of this Section (b) by the stockholders of the Corporation shall not adversely affect any right or protection of a director, officer, employee or agent of the Corporation existing at the time of such repeal or modification. ELEVENTH: In determining whether an "Acquisition Proposal" is in the best interests of the Corporation and its stockholders, the Board of Directors may, to the extent permitted by law, consider all factors it deems relevant including, without limitation, the following: (a) The consideration being offered in the Acquisition Proposal, not only in relation to the then current market price, but also in relation to the then current value of the Corporation in a freely negotiated transaction and in relation to the Board of Directors' estimate of the future value of the Corporation as an independent entity; and (b) Such other factors the Board of Directors determines to be relevant, including among others the social, legal and economic effects upon employees, suppliers, customers and the communities in which the Corporation is located, as well as on the long term business prospects of the Corporation. "Acquisition Proposal" means any proposal of any person (i) for a tender offer, exchange offer or any other method of acquiring any equity securities of the Corporation with a view to acquiring control of the Corporation, (ii) to merge or consolidate the Corporation with another corporation, or (iii) to purchase or otherwise acquire all or substantially all of the properties and assets of the Corporation. This Article ELEVENTH shall not be interpreted to create any rights on behalf of third persons, such as employees, suppliers, or customers. TWELFTH: The Corporation has elected to be governed by Section 203 of the General Corporation Law of Delaware." 7
