Vesting Eligibility of PRSUs. Subject to the terms and conditions set forth in the Plan and this Agreement, the PRSUs will be eligible for vesting as follows:

General. Except as otherwise provided in Section 2(b), the PRSUs will be eligible for vesting based on the attainment of certain Performance Goals during the Performance Periods as set forth on Appendix A. The Committee will, promptly after the filing of the Company’s Form 10-K (or other report publicly furnished to the U.S. Securities and Exchange Commission (“SEC”)) for each of the Performance Periods, review the applicable financial data as reported in the Form 10-K (or such other report referenced above) and determine whether and to what extent the Performance Goals for each Performance Period set forth in

Effect of Involuntary Termination in connection with Change in Control. Any portion of the Total Award not previously forfeited will become fully vested immediately upon the Participant’s termination of Service in the event that (A) the Participant’s Service is terminated by the Company or a Subsidiary for any reason other than Cause, death or Disability or (B) the Participant resigns for Good Reason, in each case, at the time of, or during the period commencing on the date three (3) months prior to a Change in Control and ending twenty-four (24) months following such Change in Control. (either of such events of termination within such period, a “CIC Termination”).

For purposes of this Agreement, “Cause,” “Change in Control,” and “Good Reason” shall have the meanings ascribed to such terms in the INC Research Holdings, Inc. Executive Severance Plan (the “Severance Plan”).

This Section 2(b) shall be interpreted consistently with the provisions of the Severance Plan to give effect to the benefits intended to be provided under the Severance Plan, without regard to whether the Participant is an Eligible Executive under the Severance Plan. Further, the vesting acceleration benefits provided under this Section 2(b) shall be subject to the conditions set forth in the Severance Plan.

Any vesting acceleration provisions contemplated under this Section 2(b) shall be subject to the limitations provided in Section 5.5 of the Plan.

Any PRSUs that vest pursuant to this Section 2(b) shall also be subject to the additional settlement provisions and subject to the conditions set forth in the Severance Plan.

The provisions in this Section 2(b) shall apply without regard to whether the Participant is an Eligible Executive under the Severance Plan.

Settlement in Stock. PRSUs eligible for vesting as described in Section 2 above will be settled by delivering to Participant a number of Shares equal to the number of PRSUs that are eligible to vest on the Vesting Date (as hereafter defined). For purposes of this Agreement, the “Vesting Date” will be the earlier of (x) the date on which the Committee approves the achievement of the Performance Goals after the filing of the Form 10-K for the year ending December 31, 2019 (or such other report referenced in Section 2(a) above), provided that the Participant must remain in Service through such date, or (y) the date on which a CIC Termination occurs, in each case subject to the provisions of Section 14(l) of this Agreement and any additional restrictions on settlement and subject to the conditions set forth in the Severance Plan.

Book-­Entry Registration of the Shares; Delivery of Shares. The Company shall issue the Shares payable pursuant to this Agreement within the settlement period set forth in Section 3(b) by registering such Shares with the Company’s transfer agent (or another custodian selected by the Company) in book­-entry form in the Participant’s name. In any case, the Company may provide a reasonable delay in the issuance or delivery of the Shares to address Tax­-Related Items, withholding, and other administrative matters provided that any such delay does not result in a violation of Section 409A of the Code (to the extent the Participant is a U.S. taxpayer). Neither the Company nor the Committee will be liable to the Participant or any other Person for damages relating to any delays in issuing the Shares or any mistakes or errors in the issuance of the Shares.

Shareholder Rights. The Participant will not have any rights of a stockholder with respect to the Shares subject to the PRSUs, including voting and dividend rights, unless and until the Shares are delivered as described in Section 3(b) above.

Responsibility for Taxes. The Participant acknowledges that, regardless of any action taken by the Company or, if different, the Subsidiary employing or retaining the Participant (the “Employer”), the ultimate liability for all Tax-Related Items is and remains the Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer. The Participant further acknowledges that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PRSUs, including, but not limited to, the grant or vesting of the PRSUs, the delivery of Shares following the Vesting Date, the subsequent sale of Shares acquired pursuant to such vesting/delivery and the

Withholding Requirements. Prior to any relevant taxable or tax withholding event, as applicable, the Participant agrees to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Participant authorizes the Company and/or the Employer, or their respective agents, at the Company’s and/or the Employer’s discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following: (1) cash payment by the Participant to the Company prior to the day of vesting of an amount that the Company will apply to the required withholding; (2) withholding from the Participant’s wages or other cash compensation paid to the Participant by the Company and/or the Employer; (3) withholding from proceeds of the sale of Shares acquired upon vesting/settlement of the PRSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on the Participant’s behalf pursuant to this authorization); or (4) withholding in Shares to be issued upon settlement of the PRSUs. For purposes of alternative (4) above, any Shares withheld shall be credited for purposes of the withholding requirements at the Fair Market Value of the Shares on the date that the tax withholding is determined. Until such time as the Company provides notice to the contrary, it will collect withholding for Tax-Related Items pursuant to alternative (3) above; provided, however, that if such method (A) cannot be processed by the broker or (B) the Participant is subject to the Company’s Policy on Insider Trading and Communications with the Public (the “Insider Trading Policy”), the sale of Shares pursuant to alternative (3) is prohibited under the Insider Trading Policy and the Participant has not entered into an arrangement that is intended to comply with the requirements of Rule 10b5-1(c)(1) of the Exchange Act and that provides for the sale of all of the Shares subject to this Agreement, the Company will instead collect withholding for Tax-Related Items pursuant to alternative (4).

Forfeiture. Except as provided in Section 2(b) above relating to certain terminations of Service occurring in connection with a Change in Control, all PRSUs (whether eligible for vesting or not) will be forfeited immediately, automatically and without consideration upon a termination of the Participant’s Service for any reason (whether or not later to be found invalid or in breach of employment laws in the jurisdiction where the Participant is employed or the terms of the Participant’s employment agreement, if any), including a Participant’s change in status from employee to consultant or other personal service provider, prior to the Vesting Date. In addition, any PRSUs for a given Performance Period which are not eligible for vesting after determination of the attainment of the Performance Goals for such Performance Period will be forfeited as of the date of certification by the Committee and will not carry over to subsequent Performance Periods. Without limiting the generality of the foregoing, the PRSUs and the Shares (and any resulting proceeds) will continue to be subject to Section 13 of the Plan.

Adjustment to PRSUs. In the event of any change with respect to the outstanding Shares contemplated by Section 4.5 of the Plan, the PRSUs may be adjusted in accordance with Section 4.5 of the Plan.

the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan;

the grant of the PRSUs is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of PRSUs, or benefits in lieu of PRSUs, even if PRSUs have been granted in the past;

the PRSUs and the Participant’s participation in the Plan shall not create a right to employment or be interpreted as forming an employment or services contract with the Company or any Subsidiary;

the Participant is voluntarily participating in the Plan;

the PRSUs and the Shares subject to the PRSUs are not intended to replace any pension rights or compensation;

the PRSUs and the Shares subject to the PRSUs, and the income and value of same, are not part of normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, holiday pay, long-service awards, pension or retirement or welfare benefits or similar payments;

unless otherwise agreed with the Company, the PRSUs and the Shares subject to the PRSUs, and the income and value of same, are not granted as consideration for, or in connection with, the service that the Participant may provide as a director of a Subsidiary;

the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

no claim or entitlement to compensation or damages shall arise from forfeiture of the PRSUs resulting from the termination of the Participant’s Service (for any reason whatsoever whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or the terms of the Participant’s employment agreement, if any);

the following provision shall not apply to Participants in the state of California: In consideration of the grant of the PRSUs to which the Participant is otherwise not entitled, the Participant irrevocably agrees never to institute any claim against the Company or any of its Subsidiaries, waives his or her ability, if any, to bring any such claim, and releases the Company and its Subsidiaries from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, the Participant shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim;

The following provision applies if the Participant is providing services outside the United States: neither the Company nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between the Participant’s local currency and the United States Dollar that may affect the value of the PRSUs or of any amounts due to the Participant pursuant to the settlement of the PRSUs or the subsequent sale of any Shares acquired upon settlement.
