2. Appointment of the Sarissa Group’s Nominee and the Additional Designee to the Board, and Committees of the Board.

2.1 The Company will on the date hereof add Xx. Xxxxxxxxx X. Xxxxxx (the “Sarissa Designee”) to the Board as a Class 1 director with a term expiring at the Company’s 2016 annual meeting of stockholders by increasing the size of the Board by one seat and appointing the Sarissa Designee to fill the resulting vacancy. Upon his appointment to the Board and while a member of the Board, the Company also agrees to appoint the Sarissa Designee to the Nominating and Corporate Governance Committee of the Board. The Company represents that the only Board committees are: the Audit Committee, the Compensation Committee, the Nominating and Corporate Governance Committee, the NOL Committee and the Science and Medicine Committee. So long as the Sarissa Designee is a member of the Board, (a) the Board will not form an Executive Committee unless the Sarissa Designee is a member and (b) all Board consideration of Extraordinary Transactions will take place only at the full Board level.

2.2 The Sarissa Designee agrees to submit (to the extent not already submitted) to the Company a fully completed copy of the Company’s standard directors’ and officers’ questionnaire, conflict of interest questionnaire, and other reasonable and customary director onboarding documentation required by the Company in connection with the appointment or election of a new director as soon as practicable on or after the date of this Agreement and to be governed by the same obligations regarding conflicts of interest, fiduciary duties, trading and disclosure policies and other governance guidelines as are applicable to all other directors of the Company. As a condition to the Sarissa Designee’s appointment to the Board and nomination at any annual meeting, the Sarissa Group, including the Sarissa Designee, agrees to provide to the Company such information as is required to be disclosed in proxy statements under applicable law or would otherwise be necessary for inclusion of the Sarissa Designee on any slate.

2.3 The Nominating and Corporate Governance Committee of the Board agrees to, and agrees to direct the Board’s search firm to, work with the Sarissa Designee to review and consider potential candidates identified by them as possible additional directors to be added to the Board. The Company agrees to appoint to the Board as a Class 2 director with a term expiring at the Company’s 2017 annual meeting of stockholders one person (the “Additional Designee”) who is (a) selected by the Board and (b) approved by the Sarissa Designee. The Company will increase the size of the Board from nine to ten members to accommodate this appointment and will make this appointment as promptly as reasonably practicable following such person becoming an Additional Designee; provided that it is expected that the Additional Designee will be appointed to the Board promptly following the 2014 Annual Meeting. Should the Additional Designee resign from the Board or be

rendered unable to, or refuse to, be appointed to, or for any other reason fail to serve or is not serving, on, the Board (other than due to the expiration of his or her term as a Class 2 director), for so long as the Sarissa Designee is a member of the Board, the Company shall cause to be added as a member of the Board a replacement (an “Additional Designee Replacement”) who is (i) selected by the Board and (ii) approved by the Sarissa Designee. Any such Additional Designee Replacement who becomes a Board member in replacement of the Additional Designee shall be deemed to be the Additional Designee for all purposes under this Agreement. For the avoidance of doubt, any discussions and matters considered with respect to any potential Additional Designee or Additional Designee Replacement, including which potential Additional Designees or Additional Designee replacement are discussed and whether or not the Board approves of any potential Additional Designee or Additional Designee Replacement, shall constitute Evaluation Material under the Confidentially Agreement.

2.4 The Company shall not be obligated to include either or both of the Sarissa Designee or the Additional Designee on the slate of directors proposed for election at any of the Company’s annual meetings of stockholders. So long as the Sarissa Designee is a member of the Board, the Company shall notify the Sarissa Group in writing no less than 25 calendar days before the advance notice deadline set forth in the Company’s bylaws if the Sarissa Designee or the Additional Designee will not be nominated by the Company for election as a director at such meeting. If the Sarissa Group is so notified by the Company that the Sarissa Designee or the Additional Designee is to be so nominated, the Company shall use reasonable best efforts to cause the election of the Sarissa Designee or the Additional Designee so nominated by the Company (including listing the Sarissa Designee or the Additional Designee in the proxy statement and proxy card prepared, filed and delivered in connection with such meeting and recommending that the Company’s stockholders vote in favor of the election of the Sarissa Designee or the Additional Designee (along with all other Company nominees) and otherwise supporting him or her for election in a manner no less rigorous and favorable than the manner in which the Company supports its other nominees in the aggregate).

2.5 Notwithstanding anything to the contrary in this Agreement, if at any time after the date hereof, the members of the Sarissa Group (together with their controlled Affiliates) cease collectively to Beneficially Own an aggregate Net Long Position in at least 6,000,000 shares of Common Stock (as adjusted from time to time for any stock dividends, combinations, splits, recapitalizations and the like), then the Sarissa Designee shall promptly tender his resignation from the Board and any committee of the Board on which he is a member and the Company shall have no further obligations under this Agreement. In furtherance of the foregoing, the Sarissa Designee shall, prior to his appointment to the Board, execute an irrevocable resignation as director in the form attached hereto as Exhibit A.

2.6. The Company agrees that, from and after the date of this Agreement, so long as the Sarissa Designee is a member of the Board, (a) prior to the appointment of the Additional Designee, the Company shall not take any action, or support any person who is seeking to, increase the size of the Board above 9 directors, (b) after the appointment of the Additional Designee, the Company shall not take any action, or support any person who is seeking to, increase the size of the Board above 10 directors and (c) neither the Company nor the Board shall take any action (i) to cause a member of the Board to be part of a director class other than the class of which he or she is a member as of the date hereof or, in the case of any new director, will be a member of at the time of such director’s appointment or election or (ii) to otherwise increase or decrease the classes of directors of the Board.

CONFIDENTIALITY AGREEMENT

ARIAD Pharmaceuticals, Inc.

Xxxxxxxxx, Xxxxxxxxxxxxx 00000

February 20, 2014


To: Each of the persons listed on Schedule A hereto (the “Sarissa Group” or “you”)

Ladies and Gentlemen:

This letter agreement shall become effective upon the appointment of the Sarissa Designee to the Board of Directors (the “Board”) of ARIAD Pharmaceuticals, Inc. (the “Company”). Capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the Nomination and Standstill Agreement (the “Nomination Agreement”), dated as of February 20, 2014, among the Company and the Sarissa Group. The Company understands and agrees that, subject to the terms of, and in accordance with, this letter agreement, the Sarissa Designee may, if and to the extent he desires to do so, disclose information he obtains while serving as a member of the Board to you and your Representatives (as hereinafter defined), and may discuss such information with any and all such persons, subject to the terms and conditions of this Agreement. As a result, you may receive certain non-public information regarding the Company. You acknowledge that this information is proprietary to the Company and may include trade secrets or other business information the disclosure of which could harm the Company. In consideration for, and as a condition of, the information being furnished to you and, subject to the restrictions in paragraph 2, the persons set forth on Schedule B hereto (collectively, the “Representatives”), you agree to treat any and all information concerning or relating to the Company or any of its subsidiaries or affiliates that is furnished to you or your Representatives (regardless of the manner in which it is furnished, including in written or electronic format or orally, gathered by visual inspection or otherwise) by the Sarissa Designee, or by or on behalf of the Company, together with any notes, analyses, reports, models, compilations, studies, interpretations, documents, records or extracts thereof containing, referring, relating to, based upon or derived from such information, in whole or in part (collectively, “Evaluation Material”), in accordance with the provisions of this letter agreement, and to take or abstain from taking the other actions hereinafter set forth.

1. The term “Evaluation Material” does not include information that (a) is or has become generally available to the public other than as a result of a direct or indirect disclosure by you or your Representatives in violation of this letter agreement or any obligation of confidentiality, (b) was within your or any of your Representatives’ possession on a non-confidential basis prior to its being furnished to you by the Sarissa Designee, or by or on behalf of the Company or its agents, representatives, attorneys,

advisors, directors, officers or employees (collectively, the “Company Representatives”) or (c) is received from a source other than the Sarissa Designee, the Company or any of the Company Representatives; provided, that in the case of (b) or (c) above, the source of such information was not believed by you, after reasonable inquiry of the disclosing person, to be bound by a confidentiality agreement with or other contractual, legal or fiduciary obligation of confidentiality to the Company or any other person with respect to such information at the time the information was disclosed to you.

2. You will, and you will cause your Representatives to, (a) keep the Evaluation Material strictly confidential and (b) not disclose any of the Evaluation Material in any manner whatsoever without the prior written consent of the Company; provided, however, that you may privately disclose any of such information: (A) to your Representatives (i) who need to know such information for the sole purpose of advising you on your investment in the Company and (ii) who are informed by you of the confidential nature of such information; provided, further, that you will be responsible for any violation of this letter agreement by your Representatives as if they were parties hereto; and (B) to the Company and the Company Representatives. It is understood and agreed that the Sarissa Designee shall not disclose to you or your Representatives any Legal Advice (as defined below) that may be included in the Evaluation Material with respect to which such disclosure would constitute waiver of the Company’s attorney client privilege or attorney work product privilege; provided, however, that the Sarissa Designee may provide such disclosure of Legal Advice if the Sarissa Designee shall not have taken any action, or failed to take any action, that has the purpose or effect of waiving attorney-client privilege or attorney work product privilege with respect to any portion of such Legal Advice and if reputable outside legal counsel of national standing provides the Company with a written opinion that such disclosure will not waive the Company’s attorney client privilege or attorney work product privilege with respect to such Legal Advice. “Legal Advice” as used herein shall be solely and exclusively limited to the advice provided by legal counsel and shall not include factual information or the formulation or analysis of business strategy that is not protected by the attorney-client or attorney work product privilege.

3. In the event that you or any of your Representatives are required by applicable subpoena, legal process or other legal requirement to disclose any of the Evaluation Material, you will promptly notify (except where such notice would be legally prohibited) the Company in writing by email, facsimile and certified mail so that the Company may seek a protective order or other appropriate remedy (and if the Company seeks such an order, you will provide such cooperation as the Company shall reasonably request), at its cost and expense. Nothing herein shall be deemed to prevent you or your Representatives, as the case may be, from honoring a subpoena, legal process or other legal requirement that requires discovery, disclosure or production of the Evaluation Material if (a) you produce or disclose only that portion of the Evaluation Material which your outside legal counsel of national standing advises you is legally required to be so produced or disclosed and you inform the recipient of such Evaluation Material of the

existence of this letter agreement and the confidential nature of such Evaluation Material; or (b) the Company consents in writing to having the Evaluation Material produced or disclosed pursuant to the subpoena, legal process or other legal requirement. In no event will you or any of your Representatives oppose action by the Company to obtain a protective order or other relief to prevent the disclosure of the Evaluation Material or to obtain reliable assurance that confidential treatment will be afforded the Evaluation Material. For the avoidance of doubt, it is understood that there shall be no “legal requirement” requiring you to disclose any Evaluation Material solely by virtue of the fact that, absent such disclosure, you would be prohibited from purchasing, selling or engaging in derivative or other voluntary transactions with respect to the Common Stock of the Company or otherwise proposing or making an offer to do any of the foregoing, or you would be unable to file any proxy materials in compliance with Section 14(a) of the Exchange Act or the rules promulgated thereunder.

4. You acknowledge that (a) none of the Company or any of the Company Representatives makes any representation or warranty, express or implied, as to the accuracy or completeness of any Evaluation Material, and (b) none of the Company or any of the Company Representatives shall have any liability to you or to any of your Representatives relating to or resulting from the use of the Evaluation Material or any errors therein or omissions therefrom. You and your Representatives (or anyone acting on your or their behalf) shall not directly or indirectly initiate contact or communication with any executive or employee of, or advisor to, the Company other than the Chief Executive Officer, the Chief Financial Officer, the General Counsel, Chief Scientific Officer, Chief Medical Officer and/or such other persons approved in writing by the foregoing or the Board concerning Evaluation Material, or to seek any information in connection therewith from any such person other than the foregoing, without the prior consent of the Company; provided, however, the restriction in this sentence shall not in any way apply to the Sarissa Designee or other Board members.

5. All Evaluation Material shall remain the property of the Company. Neither you nor any of your Representatives shall by virtue of any disclosure of and/or your use of any Evaluation Material acquire any rights with respect thereto, all of which rights (including all intellectual property rights) shall remain exclusively with the Company. At any time after the date on which the Sarissa Designee is no longer a director of the Company, upon the request of the Company for any reason, you will promptly return to the Company or destroy all hard copies of the Evaluation Material and use reasonable best efforts to permanently erase or delete all electronic copies of the Evaluation Material in your or any of your Representatives’ possession or control (and, upon the request of the Company, shall certify to the Company that such Evaluation Material has been erased or deleted, as the case may be). Notwithstanding the return or erasure or deletion of Evaluation Material, you and your Representatives will continue to be bound by the obligations contained herein.

6. You acknowledge, and will advise your Representatives, that the Evaluation Material may constitute material non-public information under applicable federal and state securities laws, and that you shall not, and you shall use your reasonable best efforts to ensure that your Representatives, do not, trade or engage in any derivative or other transaction, on the basis of such information in violation of such laws.

7. You hereby represent and warrant to the Company that (i) you have all requisite company power and authority to execute and deliver this letter agreement and to perform your obligations hereunder, (ii) this letter agreement has been duly authorized, executed and delivered by you, and is a valid and binding obligation, enforceable against you in accordance with its terms, (iii) this letter agreement will not result in a violation of any terms or conditions of any agreements to which you are a party or by which you may otherwise be bound or of any law, rule, license, regulation, judgment, order or decree governing or affecting you, and (iv) your entry into this letter agreement does not require approval by any owners or holders of any equity or other interest in you (except as has already been obtained).

8. It is agreed that no delay or omission by the Company to exercise any right, power or remedy accruing to it upon any breach or default of any other party under this letter agreement shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach or default, or any acquiescence therein, or of any similar breach or default thereafter occurring; nor shall any waiver by the Company of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. It is further agreed that any waiver, permit, consent or approval of any kind or character by the Company of any breach or default under this letter agreement, or any waiver by the Company of any provisions or conditions of this letter agreement must be in writing and shall be effective only to the extent specifically set forth in writing, and that all remedies, either under this letter agreement, by law or otherwise, shall be cumulative and not alternative. Any permission, consent, or approval of any kind or character under this letter agreement shall be in writing and shall be effective only to the extent specifically set forth in such writing.

9. YOU ACKNOWLEDGE AND AGREE THAT THE VALUE OF THE EVALUATION MATERIAL TO THE COMPANY IS UNIQUE AND SUBSTANTIAL, BUT MAY BE IMPRACTICAL OR DIFFICULT TO ASSESS IN MONETARY TERMS. YOU FURTHER ACKNOWLEDGE AND AGREE THAT IRREPARABLE DAMAGE WOULD OCCUR IN THE EVENT THAT ANY OF THE PROVISIONS OF THIS LETTER AGREEMENT WERE NOT PERFORMED IN ACCORDANCE WITH ITS SPECIFIC INTENT OR WERE OTHERWISE BREACHED. ACCORDINGLY YOU AGREE THAT THE COMPANY SHALL BE ENTITLED TO AN INJUNCTION OR INJUNCTIONS, WITHOUT BOND, TO PREVENT OR CURE BREACHES OF THE PROVISIONS OF THIS LETTER AGREEMENT AND TO ENFORCE SPECIFICALLY THE TERMS AND PROVISIONS HEREOF, THIS BEING IN ADDITION TO ANY OTHER REMEDY TO WHICH THE COMPANY MAY BE ENTITLED BY LAW OR EQUITY, AND YOU EXPRESSLY WAIVE ANY DEFENSE THAT A REMEDY IN DAMAGES WOULD BE ADEQUATE.

10. This letter agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of Delaware without giving effect to the principles of conflicts of laws. Any legal action or other legal proceeding relating to this letter agreement or the enforcement of any provision of this letter agreement may be brought or otherwise commenced in any state or federal court located in the State of Delaware. Each party hereto agrees to the entry of an order to enforce any resolution, settlement, order or award made pursuant to this paragraph 10 by the state and federal courts located in the State of Delaware and in connection therewith hereby waives, and agrees not to assert by way of motion, as a defense, or otherwise, any claim that such resolution, settlement, order or award is inconsistent with or violative of the laws or public policy of the laws of the State of Delaware or any other jurisdiction.

11. This letter agreement and the Nomination and Standstill Agreement constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof. Any previous agreements among the parties relative to the specific subject matter hereof are superseded by this letter agreement and the Nomination and Standstill Agreement. Neither this letter agreement nor any provision hereof may be amended, changed, waived, discharged or terminated other than by a written instrument signed by the party against who enforcement of any such amendment, change, waiver, discharge or termination is sought.
