PRA INTERNATIONAL

FORM OF OPTION AGREEMENT

THIS OPTION AGREEMENT (the “Agreement”) evidences an agreement made as of the (the “Date of Grant”), by and between (the “Optionee”), and PRA INTERNATIONAL, a Delaware corporation (the “Corporation”).

1. Option. In consideration of the Optionee’s employment with the Corporation, the Corporation hereby grants to the Optionee the option to purchase that number of shares of the Corporation’s Common Stock at the exercise price set forth on Schedule 1 hereto (the “Option”), subject to the terms and conditions of this Option Agreement and the PRA International 2004 Incentive Award Plan (the “Plan”) (attached at Exhibit 1). The Option is intended to qualify as an “incentive stock option” within the meaning of Section 422 of the Code. To the extent that the Option does not so qualify that portion of the Option shall be treated as a non-qualified option under Section 422 of the Code. All capitalized terms not otherwise defined herein shall have the meanings ascribed thereto in the Plan.

2. Vesting of Options.

(a) The Option shall vest in accordance with the terms set forth on Schedule 1 and the terms of Section 3 hereof.

(b) Unless sooner terminated in accordance with the terms hereof, the Option shall terminate (whether or not vested) on the seventh (7th) anniversary of the Date of Grant.

3. Expiration of the Option.

(a) Death or Disability of Optionee. In the event that the Optionee’s employment is terminated by reason of death or disability, the unvested portion of the Option that would otherwise vest on the next anniversary of the Date of Grant will automatically vest on a pro rata basis for the period commencing on the Date of Grant or, if applicable, the most recent anniversary of the Date of Grant and ending on the date the Optionee’s employment is so terminated, and all other unvested Options will automatically terminate. The vested portion of the Option shall be exercisable by the Optionee’s beneficiary or estate for a period of the earlier of (i) eighteen (18) months following Optionee’s death or disability or (ii) the seventh (7th) anniversary of the Date of Grant. If the vested portion of the Option is not exercised within the earlier of (i) eighteen (18) months following Optionee’s death or disability or (ii) the seventh (7th) anniversary of the Date of Grant, then such vested portion of the Option shall expire and shall no longer be exercisable.

(b) Cause. In the event that the Optionee’s employment is terminated by the Corporation for Cause (as defined below) the Option will automatically terminate and expire and shall no longer be exercisable, whether or not previously vested. For purposes of this Agreement, “Cause” shall mean: (i) a material failure of the Optionee to perform his duties and functions as an employee; (ii) Optionee engaging in or causing an act that has a material adverse impact on the reputation, business, business relationships or financial condition of the Corporation; (iii) the conviction of or plea of guilty or nolo contendere by Optionee to a felony

or any crime involving moral turpitude; or (iv) Optionee’s gross misconduct, dishonesty, or fraud.

(c) Other Termination. In the event that the Optionee’s employment is terminated for any reason other than death, disability or Cause, the unvested portion of the Option will automatically terminate. The Optionee shall have the right, in the Optionee’s sole discretion, for a period of ninety (90) days following such termination of employment to exercise the Option. If the Optionee does not exercise the vested portion of the Option within 90 days after his/her employment so terminates, then the Option shall expire and shall no longer be exercisable. Notwithstanding the foregoing, if the Optionee is precluded from selling shares upon expiration of such 90 day period because of the Corporation’s policies on insider trading or applicable securities laws restrictions, the Optionee shall have the right to exercise the vested portion of the Option for thirty (30) days following the date Optionee is able to sell shares under the Corporation’s policies on insider trading or applicable securities laws restrictions (but not beyond the seventh (7th) anniversary of the Date of Grant).

(d) Forfeiture for Competition.

(1) If Optionee is terminated under Section 7(a), 8(i)(A), or 8(ii)(A) of Optionee’s Employment Agreement (hereby incorporated by reference), Optionee agrees that during Optionee’s employment and during a period of 12 months thereafter (the “Noncompetition Period”), Optionee, shall not, whether as owner, manager, officer, director, employee, consultant or otherwise, be engaged or employed by a Competing CRO to provide Customer Services that are the same or substantially related to the Customer Services that Optionee performed for the Corporation at any time during the twenty-four (24) months prior to the termination of Optionee’s employment (the “Prohibited Services”).

(2) If Optionee is terminated under either Section 8(i)(B) or 8(ii)B) of Optionee’s Employment Agreement, Optionee agrees that for a period of 12 months after Optionee’s employment with the Corporation ceases (the “Change in Control Noncompetition Period”), Optionee will not whether as owner, manager, officer, director, employee, consultant or otherwise, be engaged or employed by a Change in Control Competing CRO to provide Customer Services that are the same or substantially related to the Customer Services that Optionee performed for the Corporation at any time during the twenty-four (24) months prior to the Termination Date.

(3) In the event that Optionee breaches either Section 3(d)(1) or 3(d)(2) of this Agreement, then in addition to other remedies available to the Corporation, Optionee shall immediately forfeit all rights under the Option that may have been granted to Optionee or to which Optionee may be entitled, whether the same are then vested or not. In addition, to the extent that Optionee exercises any of the Option during the Noncompetition Period and provides Prohibited Services then such exercise shall be rescinded and all such shares of common stock of the Corporation purchased by Optionee pursuant to the exercise of such Option during the Noncompetition Period may be repurchased by the Corporation, in its sole discretion, at the price paid by Optionee for such shares of common stock. To the extent that the Optionee has sold or otherwise disposed of any shares acquired upon exercise of the Option, then the Optionee shall pay back to the Corporation any and all proceeds received by the Optionee as

a result of such sale or other disposition. The Optionee shall also return all dividends or other distributions, if any, paid on such shares. The Corporation acknowledges and agrees that ownership by Optionee of not more than one percent (1.0%) of the shares of any corporation having a class of equity securities actively traded on a national securities exchange shall not be deemed, in and of itself, to violate the prohibitions set forth in this section.

For the purposes of this Agreement, the term “Customer Services” means any product or service provided by the Corporation to a third party for remuneration, including, but not limited to on a contract or outsourced basis, assisting pharmaceutical or biotechnology companies in developing and taking drug compounds, biologics, and drug delivery devices through appropriate regulatory approval processes, (i) during Optionee’s employment with the Corporation or (ii) about which Optionee has material knowledge and that Optionee knows the Corporation will provide or has contracted to provide to third parties during the twelve (12) months following the Optionee’s employment with the Corporation. “Customer” means any person or legal entity (and its subsidiaries, agents, employees and representatives) about whom Optionee has acquired material information based on employment with the Corporation and as to whom Optionee has been informed that the Corporation provides or will provide Customer Services. “Competing CRO” means any of the following entities and their affiliates and successors to the extent that and for so long as those said entities, affiliates, and successors directly compete with the Corporation in the provision of Customer Services to Customers: Charles River Laboratories International, Inc., Covance Inc., ICON plc, INC Research, Inc., Kendle International Inc., MDS Pharma Services, Omnicare, Inc., PAREXEL International Corporation, Pharmaceutical Product Development, Inc., PharmaNet Development Group, Inc., Quintiles Transnational Corp., United BioSource Corporation, and United HealthCare Corporation. “Change in Control Competing CRO” means any entity (and its respective affiliates and successors) that competes with the Corporation in the provision of Customer Services to Customers as a contract research organization and assumes, as an independent contractor with a drug sponsor, one or more of the obligations of a drug sponsor, e.g., design of a protocol, selection or monitoring of investigations, evaluating reports, and preparation of material to be submitted to the Food and Drug Administration or applicable regulatory agency. For purposes of this Section, “Change in Control” shall be as defined under the Plan.

4. Exercise of Option. To the extent exercisable, the Optionee may exercise the vested portion of the Option at anytime in whole or in part prior to its termination under Section 2(b) or Section 3 above by giving written notice of such exercise to the Corporation, in such form and at such time as the Corporation may specify from time to time. As a condition to the exercise of any portion of the Option, the Optionee may be required to execute such documents and make such representations as the Corporation may require in order to comply with applicable law. The Option may not be exercised until Optionee shall have delivered to the Corporation the aggregate exercise price per Share of the number of Shares for which the Option is being exercised. The exercise price may be paid by any method prescribed in Section 5.1(c) of the Plan.

5. Construction and Binding Effect. This Agreement shall be construed according to the laws of the State of Delaware, without giving effect to any conflict or choice of law provision, and shall bind the parties, their permitted assigns and their personal representatives.
