NOTICE REGARDING PROPOSAL TWO – APPROVAL OF THE AMENDMENT AND RESTATEMENT

OF THE ALLSCRIPTS 2019 STOCK INCENTIVE PLAN

To the Stockholders of Allscripts Healthcare Solutions, Inc.:

As described in the proxy statement dated April 6, 2020 (the “Proxy Statement”) of Allscripts Healthcare Solutions, Inc. (the “Company”) for the Annual Meeting of Stockholders to be held on May 21, 2020 (the “Annual Meeting”), the Company is requesting that the stockholders of the Company approve an amendment and restatement of the Allscripts Healthcare Solutions, Inc. 2019 Stock Incentive Plan (as amended and restated, the “Amended and Restated 2019 Stock Incentive Plan”).

After distributing the Proxy Statement, the Company approved an update to the proposed Amended and Restated 2019 Stock Incentive Plan to reduce the increase in the number of new shares that may be granted as awards under the Amended and Restated 2019 Stock Incentive Plan from 5,100,000 shares to 3,900,000 shares, thereby reducing the aggregate number of shares authorized for issuance under the Amended and Restated 2019 Stock Incentive Plan from 10,600,000 shares to 9,400,000 shares, of which 6,799,197 shares (consisting of 2,899,197 shares available for grant as of May 1, 2020 plus 3,900,000 shares being requested for stockholder approval), rather than 7,000,563 shares, would be available for new awards, not including any shares that would become available again upon the expiration, termination, cancellation, cash settlement or forfeiture of certain previously-issued awards, as described on pages 48 and 51 of the Proxy Statement. Other than the changes described above, all other terms of the Amended and Restated 2019 Stock Incentive Plan remain the same as those described in the Proxy Statement. As updated, Section 1.5 of the Amended and Restated 2019 Stock Incentive Plan is as marked below.

To provide context, we are updating the historical award data disclosure included in Proposal Two of the Proxy Statement to reflect the 2020 equity grants through May 1, 2020, which includes the equity grants made under the Company’s annual equity grant program.

The table below summarizes outstanding equity awards of the Company as of May 1, 2020.

Overhang Data

The following table summarizes, as of May 1, 2020, 2019, the Company’s issued and total equity overhang as compared with the Company’s peer group described in the “Compensation Discussion and Analysis” section of this proxy statement. The peer group data was compiled by Compensia, the Compensation Committee’s compensation consultant, based on publicly available data as of January 2020.

Marked Change to Section 1.5 of the Amended and Restated 2019 Stock Incentive Plan.

1.5. Shares Available. Subject to adjustment as provided in Section 5.7 and to all other limits set forth in this Section 1.5, the number of shares of Common Stock that shall initially be available for all awards under this Plan shall be (i) 9,400,000, plus (ii) the number of available shares of Common Stock under the Allscripts Healthcare Solutions, Inc. Second Amended and Restated 2011 Stock Incentive Plan as of the Effective Date. The number of shares of Common Stock that remain available for future grants under the Plan shall be reduced by the sum of the aggregate number of shares of Common Stock that become subject to outstanding options, outstanding Free-Standing SARs, outstanding Stock Awards and outstanding Performance Units denominated in shares of Common Stock, other than Substitute Awards. If this Plan is approved by the stockholders of the Company, no further awards may be granted under any Prior Plan.

To the extent that shares of Common Stock subject to an outstanding option, SAR or stock award granted under this Plan or under any Prior Plan are not issued or delivered by reason of (i) the expiration, termination, cancellation or forfeiture of such award (excluding shares subject to an option cancelled upon settlement in shares of a related tandem SAR or shares subject to a tandem SAR cancelled upon exercise of a related option) or (ii) the settlement of such award in cash, then such shares of Common Stock shall again be available under this Plan; provided, however, that shares of Common Stock subject to an award under this Plan or any Prior Plan shall not again be available under this Plan if such shares are (x) shares that were subject to a stock-settled SAR and were not issued or delivered upon the net settlement of such SAR, (y) shares delivered to or withheld by the Company to pay the purchase price or the withholding taxes related to an outstanding award and (z) shares repurchased by the Company on the open market with the proceeds of an option exercise. The number of shares subject to outstanding awards granted under a Prior Plan that shall become available under this Plan pursuant to this paragraph shall be based on whatever factor or factors that were applied to determine the number of shares originally deducted from the available shares under the Prior Plan. The number of shares of Common Stock available for awards under this Plan shall not be reduced by (i) the number of shares of Common Stock subject to Substitute Awards or (ii) available shares under a stockholder approved plan of a company or other entity which was a party to a corporate transaction with the Company (as appropriately adjusted to reflect such corporate transaction) which become subject to awards granted under this Plan (subject to applicable stock exchange requirements). Shares of Common Stock to be delivered under this Plan shall be made available from authorized and unissued shares of Common Stock, or authorized and issued shares of Common Stock reacquired and held as treasury shares or otherwise or a combination thereof.

The Amended and Restated 2019 Stock Incentive Plan, as updated, will be presented for stockholder approval at the Annual Meeting, and its effectiveness remains conditioned on the receipt of such approval. If a stockholder returns his or her proxy card or votes via the Internet or by telephone at any time (either prior to or after the date of this Notice) indicating in favor of Proposal Two, such vote will constitute a vote in favor of such Proposal, as updated by this Notice. If any stockholder has already returned his or her properly executed proxy card or voted via the Internet or by telephone and would like to change his or her vote on any matter, such stockholder may revoke his or her proxy and change his or her vote prior to the applicable cutoff time. A stockholder may change his or her vote using the Internet or telephone methods described in the Proxy Statement, in which case only his or her latest Internet or telephone proxy submitted prior to the Annual Meeting will be counted. A stockholder may also revoke his or her proxy and change his or her vote by signing and returning a new proxy card or voting instruction form dated as of a later day or by properly registering for and voting during the Annual Meeting. If any stockholder would like a new proxy card or has any questions, he or she should contact the Company’s Corporate Secretary at legal.notices@allscripts.com.

Sincerely,

Brian P. Farley

Executive Vice President, Chief Administrative Officer,

General Counsel and Corporate Secretary
