AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and of the respective covenants and agreements set forth below, the Parties hereto agree as follows:

1. Employment.

(a)     General. The Company shall employ Executive and Executive shall enter the employ of the Company, for the period and in the position set forth in this Section 1, and upon and subject to the other terms and conditions herein provided.

(b)     Employment Term. The term of employment under this Agreement (the “Term”) shall be for the period beginning on the Effective Date and ending on December 31, 2014, subject to earlier termination as provided inSection 3. The Term shall automatically renew for additional one (1) year periods unless no later than sixty (60) days prior to the end of the otherwise applicable Term either Party

gives written notice ofnon-extension of the Term to the other, in which case Executive’s employment will terminate at the end of the then applicable Term or any other date set by the Company in accordance with Section 3, subject to earlier termination as provided in Section 3.

(c)     Position and Duties. Executive shall serve as the Chief Operating Officer of the Company and Parent and shall report directly to the Company’s and Parent’s Chief Executive Officer. As Chief Operating Officer, Executive shall have such customary responsibilities, duties and authority normally associated with such position and as may from time to time be assigned to Executive by the Chief Executive Officer of the Company or the Board (as defined below). Executive shall devote substantially all of Executive’s working time and efforts to the business and affairs of the Company (which shall include service to its subsidiaries and affiliates) and shall not engage in outside business activities (including serving on outside boards or committees) without the consent of the Board, provided that Executive shall be permitted to (i) manage Executive’s personal, financial and legal affairs, (ii) participate in trade associations and (iii) serve on the board of directors ofnot-for-profit ortax-exempt charitable organizations, in each case, subject toSection 5 and provided that such activities do not interfere with Executive’s performance of Executive’s duties and responsibilities hereunder. The Executive agrees to observe and comply with the rules and policies of the Company and its affiliates as adopted from time to time, in each case as amended from time to time, as delivered or made available to Executive (each, a “Policy”).

2. Compensation and Related Matters.

(a)     Annual Base Salary. Beginning on the Effective Date, Executive shall receive a base salary at a rate of $475,000 per annum, which shall be paid in accordance with the customary payroll practices of the Company. Such annual base salary shall be reviewed and may be adjusted from time to time by the board of directors of the Company or an authorized committee thereof, (in any case, the “Board”), provided that the annual base salary may not be decreased without Executive’s consent (such annual base salary, as it may be increased from time to time, the “Annual Base Salary”). Not later than the end of the first payroll period following the date this Agreement is executed by Executive, the Company shall pay to Executive a lump sum payment equal to the additional base salary that would have been paid to Executive from and after December 5, 2011 if Executive’s base salary was increased to $475,000 effective December 5, 2011.

(b)     Bonus. Executive will be eligible to participate in an incentive program established by the Board. Executive’s annual bonus compensation under such incentive program (the “Annual Bonus”) shall be targeted at 75% of the Annual Base Salary (the “Target Bonus Amount”). The Annual Bonus shall initially be based 70% upon a Company-wide bonus pool to be determined by the Board based upon the achievement of Company performance metrics established by the Board in good faith after consultation with the Company’s Chief Executive Officer and 30% upon achievement of individual qualitative factors as determined by the Board in its discretion. The payment of any Annual Bonus shall be subject to Executive’s continued employment with the Company through the date of payment; provided however that if Executive’s employment shall terminate (other than as a result of the Company’s termination of the Executive’s employment for Cause pursuant to Section 3(a)(iii) or as a result of the Executive’s resignation without Good Reason pursuant to Section 3(a)(vi)) on or after January 1 of an applicable year, Executive shall be entitled to receive any earned but unpaid Annual Bonus for the prior year pursuant to this Section 2(b). For sake of clarity, Executive’s Annual Bonus for 2012 shall be calculated and determined as if Executive’s base salary was increased to $475,000 per annum effective as of January 1, 2012.

(c)     Benefits. During the Term, Executive shall be eligible to participate in employee benefit plans, programs and arrangements of the Company to the same extent as other senior-level executives

2

(excluding aircraft use, severance benefits or the right to receive equity compensation) consistent with the terms thereof and as such plans, programs and arrangements may be amended from time to time. In no event shall Executive be eligible to participate in any severance plan or program of the Company, except as set forth inSection 4 of this Agreement.

(d)     Vacation. During the Term, Executive shall be entitled to not less than 30 days of paid personal leave in accordance with the Company’s Policies. Any vacation shall be taken at the reasonable and mutual convenience of the Company and Executive.

(e)     Expenses. During the Term, the Company shall reimburse Executive for all reasonable travel and other business expenses incurred by Executive in the performance of Executive’s duties to the Company in accordance with the Company’s expense reimbursement Policy.

(f)     Key Person Insurance. At any time during the Term, the Company shall have the right to insure the life of Executive for the Company’s sole benefit. The Company shall have the right to determine the amount of insurance and the type of policy. Executive shall reasonably cooperate with the Company in obtaining such insurance by submitting to physical examinations, by supplying all information reasonably required by any insurance carrier, and by executing all necessary documents reasonably required by any insurance carrier, provided that any information provided to an insurance company or broker shall not be provided to the Company without the prior written authorization of Executive. Executive shall incur no financial obligation by executing any required document, and shall have no interest in any such policy. Additionally, and notwithstanding the preceding to the contrary, in the event the amount of insurance adversely affects the amount of life insurance the Executive seeks and is qualified to obtain at any time during the Term, then the Company agrees to reduce the amount of the insurance.

(g)     Aircraft Use. Executive shall be entitled to use the Company’s aircraft for personal use up to a maximum of 10,000 miles per year, subject to the terms and conditions of the Company’s aircraft use policy as may be amended from time to time. The Parties acknowledge that at any time the Company may elect to discontinue its ownership of an aircraft and for any period during the Term when the Company does not own an aircraft, Executive shall be entitled to receive as compensation in lieu of such personal use of the Company’s aircraft an amount in cash equal to $25,000 per annum, which amount shall be prorated for any partial year and shall be payable in accordance with the Company’s standard payroll practices, except as otherwise explicitly provided herein.

A Notice of Termination submitted by the Company may provide for a Date of Termination on the date Executive receives the Notice of Termination, or any date thereafter elected by the Company in its sole discretion. The failure by the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause shall not waive any right of the Company hereunder or preclude the Company from asserting such fact or circumstance in enforcing the Company’s rights hereunder.

(c)     Company Obligations upon Termination. Upon termination of Executive’s employment pursuant to any of the circumstances listed inSection 3(a), Executive (or Executive’s estate) shall be entitled to receive the sum of: (i) the portion of Executive’s Annual Base Salary earned through the Date of Termination but not yet paid to Executive; (ii) any expenses owed to Executive pursuant toSection 2(e); and (iii) any amount accrued and arising from Executive’s participation in, or benefits accrued under any employee benefit plans, programs or arrangements, which amounts shall be payable in accordance with the terms and conditions of such employee benefit plans, programs or arrangements (collectively, the “Company Arrangements”). Except as otherwise expressly required by law (e.g., COBRA) or as specifically provided herein, all of Executive’s rights to salary, severance, benefits, bonuses and other compensatory amounts hereunder (if any) shall cease upon the termination of Executive’s employment hereunder. In the event that Executive’s employment is terminated by the Company for any reason and the Company is not in breach of this Agreement, Executive’s sole and exclusive rights under this Agreement shall be to receive the payments and benefits described inSection 2(b), thisSection 3(c) and/orSection 4, as applicable.

5. Competition.

Executive acknowledges that the Company has provided and, during the Term, the Company from time to time will continue to provide Executive with access to its confidential information. Ancillary to the rights provided to Executive as set forth in this Agreement and the Company’s provision of confidential information, and Executive’s agreements regarding the use of same, in order to protect the value of any confidential information, the Company and Executive agree to the following provisions against unfair competition, which Executive acknowledges represent a fair balance of the Company’s rights to protect its business and Executive’s right to pursue employment:

(a)     Executive shall not, at any time during the Restricted Period (as defined below), directly or indirectly engage in, have any equity interest in, interview for a potential employment or consulting relationship with or manage, provide services to or operate any person, firm, corporation, partnership or business (whether as director, officer, employee, agent, representative, partner, security holder, consultant or otherwise) that engages in any business which competes with any portion of the Business (as defined below) of the Company anywhere in the world. Nothing in thisSection 5(a) shall prohibit Executive from working for a pharmaceutical, biotechnology or medical device organization that is not a clinical research organization or being a passive owner of not more than 2% of the outstanding voting securities of an entity that is publicly traded, so long as Executive has no active participation in the business of such entity.

(b)     Executive shall not, at any time during the Restricted Period, directly or indirectly, recruit or otherwise solicit or induce any employee, customer, subscriber or supplier of the Company to (i) terminate its employment or arrangement with the Company, or (ii) to otherwise change its relationship with the Company. Executive shall not, at any time during the Restricted Period, directly or indirectly, either for Executive or for any other person or entity, (x) solicit any employee of the Company to terminate his or her employment with the Company, (y) employ any such individual during his or her employment with the Company and for a period of twelve months after such individual terminates his or her employment with the Company or (z) solicit any vendor or business affiliate of the Company to cease to do business with the Company.

(c)     In the event the terms of thisSection 5 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

(d)     As used in thisSection 5, (i) the term “Company” shall include the Company and its direct and indirect parents and subsidiaries; (ii) the term “Business” shall mean the business of the Company and shall include providing drug discovery or development services to pharmaceutical, biotechnology, medical device, government and academic organizations, as such business may be conducted or contemplated during the Term and (iii) the term “Restricted Period” shall mean the period beginning on the Effective Date and ending on the date that is 18 months following the Date of

6

Termination, provided, however, that if Executive’s employment is terminated by the Company without Cause or the Executive resigns for Good Reason as a result of Executive not reporting directly to the Chief Executive Officer of the Company and Parent or the Board (which the parties hereto agree shall constitute Good Reason), in either case on or before December 5, 2012, the Restricted Period shall mean the period beginning on the Effective Date and ending on the date that is 12 months following the Date of Termination.

(e)     Each of the Parties (which, in the case of the Company, shall mean its officers and the members of the Board) agrees, during the Term and following the Date of Termination, to refrain from Disparaging (as defined below) the other Party and its affiliates, including, in the case of the Company, any of its services, technologies or practices, or any of its directors, officers, agents, representatives or stockholders, either orally or in writing. Nothing in this paragraph shall preclude any Party from making truthful statements that are reasonably necessary to comply with applicable law, regulation or legal process, or to defend or enforce a Party’s rights under this Agreement. For purposes of this Agreement, “Disparaging” means making remarks, comments or statements, whether written or oral, that impugn the character, integrity, reputation or abilities of the Person being disparaged.

(f)     Executive represents that Executive’s employment by the Company does not and will not breach any agreement with any former employer, including anynon-compete agreement or any agreement to keep in confidence or refrain from using information acquired by Executive prior to Executive’s employment by the Company. During Executive’s employment by the Company, Executive agrees that Executive will not violate anynon-solicitation agreements Executive entered into with any former employer or improperly make use of, or disclose, any information or trade secrets of any former employer or other third party, nor will Executive bring onto the premises of the Company or use any unpublished documents or any property belonging to any former employer or other third party, in violation of any lawful agreements with that former employer or third party.

6. Injunctive Relief.

It is recognized and acknowledged by Executive that a breach of any covenant contained inSection 5 will cause irreparable damage to Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, Executive agrees that in the event of a breach of any covenant contained inSection 5, in addition to any other remedy which may be available at law or in equity, the Company will be entitled to specific performance and injunctive relief.

7. Assignment and Successors.

The Company may assign its rights and obligations under this Agreement to any of its affiliates provided that the Company remains secondarily liable hereunder or to any successor to all or substantially all of the business or the assets of the Company (by merger or otherwise), and may assign or encumber this Agreement and its rights hereunder as security for indebtedness of the Company and its affiliates. This Agreement shall be binding upon and inure to the benefit of the Company, Executive and their respective successors, assigns, personnel and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable. None of Executive’s rights or obligations may be assigned or transferred by Executive, other than Executive’s rights to payments hereunder, which may be transferred only by will or operation of law. Notwithstanding the foregoing, Executive shall be entitled, to the extent permitted under applicable law and applicable Company Arrangements, to select and change a beneficiary or beneficiaries to receive compensation hereunder following Executive’s death by giving written notice thereof to the Company.

The Company shall be entitled to rely on an opinion of counsel if any questions as to the amount or requirement of withholding shall arise.

(1)    Sections 409A and 280G.

(i)     General.The intent of the Parties is that the payments and benefits under this Agreement comply with or be exempt from Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations and guidance promulgated thereunder (collectively, “Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith.

(ii)     Separation from Service.Notwithstanding anything in this Agreement to the contrary, any compensation or benefits payable under this Agreement that is designated under this Agreement as payable upon Executive’s termination of employment shall be payable only upon Executive’s “separation from service” with the Company within the meaning of Section 409A (a “Separation from Service”) and, except as provided below, any such compensation or benefits shall not be paid, or, in the case of installments, shall not commence payment, until the thirtieth (30th) day following Executive’s Separation from Service. Any installment payments that would have been made to Executive during the thirty (30) day period immediately following Executive’s Separation from Service but for the preceding sentence shall be paid to Executive on the thirtieth (30th) day following Executive’s Separation from Service and the remaining payments shall be made as provided in this Agreement.

11

(iii)     Specified Employee.Notwithstanding anything in this Agreement to the contrary, if Executive is deemed by the Company at the time of Executive’s Separation from Service to be a “specified employee” for purposes of Section 409A, to the extent delayed commencement of any portion of the benefits to which Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A, such portion of Executive’s benefits shall not be provided to Executive prior to the earlier of (i) the expiration of thesix-month period measured from the date of Executive’s Separation from Service with the Company or (ii) the date of Executive’s death. Upon the first business day following the expiration of the applicable Section 409A period, all payments deferred pursuant to the preceding sentence shall be paid in a lump sum to Executive (or Executive’s estate or beneficiaries), and any remaining payments due to Executive under this Agreement shall be paid as otherwise provided herein.

(iv)     Expense Reimbursements.To the extent that any reimbursements under this Agreement are subject to Section 409A, any such reimbursements payable to Executive shall be paid to Executive no later than December 31 of the year following the year in which the expense was incurred; provided that Executive submits Executive’s reimbursement request promptly following the date the expense is incurred, the amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year, other than medical expenses referred to in Section 105(b) of the Code, and Executive’s right to reimbursement under this Agreement will not be subject to liquidation or exchange for another benefit.

(v)     Installments.Executive’s right to receive any installment payments under this Agreement, including without limitation any continuation salary payments that are payable on Company payroll dates, shall be treated as a right to receive a series of separate payments and, accordingly, each such installment payment shall at all times be considered a separate and distinct payment as permitted under Section 409A. Except as otherwise permitted under Section 409A, no payment hereunder shall be accelerated or deferred unless such acceleration or deferral would not result in additional tax or interest pursuant to Section 409A.

(vi)     Certain Terminations.The Parties acknowledge that the Transaction constituted a “change in control event” for purposes of Treasury Regulation§1.409A-3(i)(5) and a “Change in Control” as defined in the Severance Agreement. The Parties further acknowledge that severance payments provided for under the Severance Agreement were payable in a lump sum thirty (30) days following a qualifying termination of Executive employment as provided in the Severance Agreement, and the Parties intend to provide for the same payment timing for severance payments underSection 4(c) of this Agreement as would have applied in the event Executive had become entitled to severance payments under Section 2.01 of the Severance Agreement. Therefore, in the event that Executive’s employment is terminated as set forth inSection 4(c) on or before December 5, 2012, notwithstanding anything else in this Agreement to the contrary, the payments, if any, paid to Executive underSection 4(b)(i)(A) (as modified bySection 4(c)) shall be paid in a lump sum within thirty (30) days following the Date of Termination, subject to Executive’s executing and not revoking the Release as set forth inSection 4(b)(i).

(vii)     Section 280G.Parent and the Company agree that, if and to the extent Executive so requests, any payments or benefits that Executive might receive under this Agreement or otherwise that may constitute “parachute payments” (as defined in Section 280G of the Code) shall be submitted for stockholder approval in accordance with the requirements of Section 280G(b)(5) of the Code and the regulations thereunder (to the extent the stockholder approval exemption set forth in Section 280G(b)(5) is available in connection with such payments or benefits), and the Company and Parent shall recommend approval of such payments or benefits to the stockholders whose approval is required pursuant to regulations under Section 280G(b)(5) of the Code.

12

(m)     Indemnification; Insurance. During the term of this Agreement and thereafter, the Company shall indemnify and hold Executive (including Executive’s heirs, personal representatives, executors and administrators) harmless, to the maximum extent permitted by law, against any and all damages, costs, liabilities, and losses as a result of any third party (excluding the Company and any of its affiliates) claim or proceeding, or any threatened third-party (excluding the Company and any of its affiliates) claim or proceeding, against Executive that arises out of or relates to Executive by reason of Executive having been or having provided service as an officer, director or employee, as the case may be, of the Company, or Executive’s service in any such capacity or similar capacity with an affiliate of the Company or other entity at the request of the Company (in all cases, subject to limitations on bad acts and any other limitations under applicable law which preclude such indemnification and excluding any and all damages, costs, liabilities and losses related to Executive’s remuneration). The Company shall maintain or cause to be maintained for the Executive Directors’ and Officers’ insurance to the same extent provided to active officers of the Company in respect of those liabilities which Executive may incur as a director or officer of the Company or any of its affiliates for which such insurance is normally available.

(n)     Parent Guarantee. In the event that the Company shall fail to satisfy any matured payment obligation to Executive under this Agreement, Parent agrees to satisfy such payment obligation, subject to all of the terms and conditions of this Agreement and applicable law.

(o)     Reimbursement of Legal Fees. The Company shall promptly (but in no event later than December 31, 2012) reimburse Executive for legal fees incurred by Executive in connection with advice relating to this Agreement and the terms and conditions of Executive’s employment by the Company, subject to a maximum reimbursement of $20,000.

10. Employee Acknowledgement.

Executive acknowledges that Executive has read and understands this Agreement, is fully aware of its legal effect, has not acted in reliance upon any representations or promises made by the Company other than those contained in writing herein, and has entered into this Agreement freely based on Executive’s own judgment.
