AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, IMS Health and the Quintiles Shareholders hereby agree as follows:

1. Agreement to Vote. Prior to the Termination Date (as defined herein), each Quintiles Shareholder irrevocably and unconditionally agrees that it shall, at any meeting

of the shareholders of Quintiles (whether annual or special and whether or not an adjourned or postponed meeting), however called, or in connection with any action proposed to be taken by written consent of the shareholders of Quintiles (a) when a meeting is held, appear at such meeting or otherwise cause the Covered Shares to be counted as present thereat for the purpose of establishing a quorum, and respond to each request by Quintiles for written consent, if any, and (b) vote (or consent), or cause to be voted at such meeting (or validly execute and return and cause such consent to be granted with respect to), all Covered Shares (i) in favor of the adoption of the Merger Agreement and any other matter that is required to facilitate the Merger and/or the other transactions contemplated by the Merger Agreement, including the Governance Matters, and (ii) against (A) any Acquisition Proposal with respect to Quintiles (a “Quintiles Acquisition Proposal”), (B) any other action, agreement or proposal that could reasonably be expected to impede, interfere with, delay, postpone, frustrate, prevent, nullify or adversely affect the Merger or any of the transactions contemplated by the Merger Agreement or this Agreement or change in any manner the voting rights of any class of the capital stock of Quintiles, (C) any change in the present capitalization or dividend policy of Quintiles or any amendment or other change to Quintiles’s articles of incorporation or bylaws, except the Governance Matters or if approved by IMS Health, and (D) any other change in Quintiles’s corporate structure or business. In the event that such Quintiles Shareholder’s proxy has been granted to IMS Health pursuant to Section 2(a), such Quintiles Shareholder shall have no obligations under this Section 1 with respect to the meeting of the shareholders of Quintiles for which such proxy has been granted. Except as explicitly set forth in this Section 1, nothing in this Agreement shall limit the right of each Quintiles Shareholder to vote (including by proxy or written consent, if applicable) in favor of, against or abstain with respect to any matters presented to Quintiles’s shareholders.

2. Grant of Irrevocable Proxy; Appointment of Proxy.

(a) EACH QUINTILES SHAREHOLDER HEREBY GRANTS TO, AND APPOINTS, IMS HEALTH AS SUCH QUINTILES SHAREHOLDER’S IRREVOCABLE (UNTIL THE TERMINATION DATE) PROXY AND ATTORNEY-IN-FACT (WITH FULL POWER OF SUBSTITUTION) TO VOTE THE COVERED SHARES AS INDICATED IN SECTION 1. EACH QUINTILES SHAREHOLDER INTENDS THIS PROXY TO BE IRREVOCABLE (UNTIL THE TERMINATION DATE) AND COUPLED WITH AN INTEREST AND WILL TAKE SUCH FURTHER ACTION OR EXECUTE SUCH OTHER INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY AND HEREBY REVOKES ANY PROXY PREVIOUSLY GRANTED BY SUCH QUINTILES SHAREHOLDER WITH RESPECT TO THE COVERED SHARES (SUCH QUINTILES SHAREHOLDER REPRESENTING TO IMS HEALTH THAT ANY SUCH PROXY IS NOT IRREVOCABLE).

(b) It is hereby agreed that IMS Health will use the proxy granted in Section 2(a) solely in accordance with applicable Law and will only vote the Covered Shares subject to such proxy with respect to the matters and in the manner specified in Section 1.

(c) The proxy granted in Section 2(a) shall automatically terminate, and any underlying appointment shall automatically be revoked and rescinded and of no force and effect, upon the Termination Date, in each case without any further action by any party.

3. No Inconsistent Agreements. Each Quintiles Shareholder hereby represents, covenants and agrees that, except as contemplated by this Agreement, such Quintiles Shareholder (a) has not, except for the Amended and Restated Shareholders Agreement, dated as of February 5, 2015, by and among Quintiles and the Shareholders (as defined therein) (the “Quintiles SHA”), entered into, and shall not enter into at any time prior to the Termination Date, any voting agreement or voting trust with respect to any Covered Shares and (b) has not granted, and shall not grant at any time prior to the Termination Date, a proxy or power of attorney with respect to any Covered Shares, in either case, which is inconsistent with such Quintiles Shareholder’s obligations pursuant to this Agreement.

(iii) Except for the applicable requirements of the Exchange Act, (i) no filing with, and no permit, authorization, consent or approval of, any Governmental Entity is necessary on the part of such Quintiles Shareholder for the execution, delivery and performance of this Agreement by such Quintiles Shareholder or the consummation by such Quintiles Shareholder of the transactions contemplated hereby and (ii) neither the execution, delivery or performance of this Agreement by such Quintiles Shareholder nor the consummation by such Quintiles Shareholder of the transactions contemplated hereby nor compliance by such Quintiles Shareholder with any of the provisions hereof shall (A) conflict with or violate any provision of the organizational documents of such Quintiles Shareholder, (B) result in any breach or violation of, or constitute a default (or an event which, with notice or lapse of time or both, would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a Lien on such property or asset of such Quintiles Shareholder pursuant to, any Contract to which such Quintiles Shareholder is a party or by which such Quintiles Shareholder or any property or asset of such Quintiles Shareholder is bound or affected or

6. Certain Covenants of Quintiles Shareholder. Each Quintiles Shareholder, for itself (severally and not jointly), hereby covenants and agrees as follows:

(a) Subject to Section 7, prior to the Termination Date, such Quintiles Shareholder shall not, and shall not authorize or permit any of its Subsidiaries or controlled affiliates, or authorized any of their respective directors, officers, employees, consultants, financial advisors, accountants, legal counsel, investment bankers, and other agents, advisors and representatives, directly or indirectly, to:

6

provided that the provisions of this Section 6(a) shall only apply to a Quintiles Shareholder’s or its Subsidiaries’ or controlled affiliates’ consultants, financial advisors, accountants, legal counsel, investment bankers, and other agents, advisors and representatives (each, a “Third Party”) to the extent such Third Party is acting on behalf of, or was encouraged by, the Quintiles Shareholder or its Subsidiaries or controlled affiliates.

(b) Such Quintiles Shareholder will immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any of the matters described in Section 6(a) above.

(c) Prior to the Termination Date, and except as contemplated hereby, such Quintiles Shareholder shall not, without the prior written consent of IMS Health, (i) tender any Covered Shares into any tender or exchange offer, (ii) sell (constructively or otherwise), transfer, pledge, hypothecate, grant, encumber, assign or otherwise dispose of (other than to an affiliate of such Quintiles Shareholder that agrees in writing to be bound by the terms hereof and that certain Shareholders Agreement, dated as of the date hereof, by and among Quintiles and certain shareholders party thereto) (collectively, “Transfer”), or enter into any contract, option, agreement or other arrangement or understanding with respect to the Transfer of, any of the Covered Shares or beneficial ownership or voting power thereof or therein (including by operation of law), (iii) grant any proxies or powers of attorney, deposit any Covered Shares into a voting trust or enter into a voting agreement with respect to any Covered Shares or (iv) knowingly take any action that would make any representation or warranty of such Quintiles Shareholder contained herein untrue or incorrect or have the effect of preventing or disabling such Quintiles Shareholder from performing its obligations under this Agreement.

7. Quintiles Shareholder Capacity. This Agreement is being entered into by each Quintiles Shareholder solely in its capacity as a shareholder of Quintiles, and nothing in this Agreement shall restrict or limit the ability of any Quintiles Shareholder who is a director or officer of Quintiles, or any Person who is a director or officer of Quintiles who may be affiliated or associated with, or nominated by, any Quintiles Shareholder or any of its affiliates, from exercising his or her fiduciary duties as a director or officer of Quintiles or from otherwise taking any action or inaction in his or her capacity as a director or officer of Quintiles to the extent specifically permitted by the Merger Agreement, or subject to his fiduciary duties to Quintiles, or as he may otherwise be required by Law, and no such exercise of fiduciary duties or action or inaction taken in such capacity as a director or officer of Quintiles shall be deemed to constitute a breach of this Agreement. For the avoidance of doubt, nothing in this Section 7 is intended to limit the obligations of Quintiles under the Merger Agreement.

13. Waiver. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder. Any agreement on the part of a party to any such waiver shall be valid only if set forth in a written instrument executed and delivered by a duly authorized officer on behalf of such party.
