Continued growth in outsourced research and development spendingGrowth in our industry derives both from growth in the research and development budgets of the biopharmaceutical industry and from increases in the proportion of those budgets directed to outsourced service providers. According to Frost and Sullivan, research and development spending by the biopharmaceutical industry is expected to grow at a rate of approximately 7.7% per year from 2009 to 2015. This growth is expected to be driven by increased competition, product

AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER, dated as of April 26, 2007 (this “Agreement”), by and among Cross Shore Acquisition Corporation, a Delaware corporation (“Parent”), Longxia Acquisition, Inc., a Pennsylvania corporation (“Merger Sub”), ReSearch Pharmaceutical Services, Inc., a Pennsylvania corporation (“Target”), the RPS Securityholders that execute a signature page to this Agreement or a Letter of Transmittal and Daniel M. Perlman and Daniel Raynor (the “RPS Securityholders Committee”).

     WHEREAS, Target and Parent believe that it is in the best interests of their companies and their respective stockholders for Parent to acquire all of the outstanding capital stock of Target through the merger of Merger Sub with and into Target with Target being the surviving corporation (the “Merger”), upon the terms and subject to the conditions set forth in this Agreement and in accordance with the relevant provisions of the Pennsylvania Business Corporation Law of 1988, as amended (the “PABCL”), followed by the merger of the surviving corporation of the Merger with and into Merger Sub Two (the “Second Merger”); and

     WHEREAS, Target and Parent desire to make certain representations, warranties, covenants and agreements in connection with the transactions contemplated hereby.

     NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement, the parties agree as follows:

Article I.
The Merger

     Section 1.1 The Merger. At the Effective Time and upon the terms and subject to satisfaction or waiver of the conditions set forth in this Agreement, Merger Sub shall be merged with and into Target. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and Target shall continue as the surviving corporation of the Merger (the “Surviving Corporation”).

     Section 1.2 Effective Time. Unless this Agreement is terminated pursuant to Section 8.1, as promptly as practicable, and in any event within three (3) business days, after the conditions set forth in Article VII hereof are satisfied or waived (other than those conditions that by their nature are to be satisfied at the Closing), the parties shall cause the Merger to be consummated by executing and filing a certificate of merger, substantially in the form attached hereto as Exhibit A (the “Certificate of Merger”), with the Secretary of the Commonwealth of the Commonwealth of Pennsylvania (the date and time of such filing, or such later date or time as is specified in the Certificate of Merger, is referred to herein as the “Effective Time”). A closing (the “Closing”) will take place at the offices of McDermott Will & Emery LLP, 227 West Monroe Street, Chicago, Illinois 60606, on the date of such filing (such date on which the Closing actually occurs, the “Closing Date”).

     Section 1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the PABCL. Without limiting the generality of the foregoing, at the Effective Time all the properties, rights, privileges, powers and franchises of

Target and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities, obligations and duties of Target and Merger Sub shall become the debts, liabilities, obligations and duties of the Surviving Corporation.

     Section 1.4 Governing Documents. At the Effective Time, the articles of incorporation and by-laws of Target, as in effect immediately prior to the Effective Time, shall automatically, and without further action, become the articles of incorporation and by-laws of the Surviving Corporation and thereafter will continue to be its articles of incorporation and by-laws until further amended as provided therein and in accordance with the relevant provisions of the PABCL.

     Section 1.5 Directors and Officers. The initial directors of the Surviving Corporation at the Effective Time shall be Daniel M. Perlman (as Chair), Edward V. Yang, Harris Koffer, Dennis M. Smith, Stephen E. Stonefield, Daniel Raynor and James Macdonald, each to hold office in accordance with the articles of incorporation and by-laws of the Surviving Corporation until his or her successor is duly elected or appointed and qualified. The initial officers of the Surviving Corporation and Parent at the Effective Time and of Merger Sub Two following consummation of the Second Merger shall be Daniel M. Perlman as Chief Executive Officer and Chairman of the Board; Harris Koffer as President and Chief Operating Officer; and Steven Bell as Executive Vice President, Chief Financial Officer, Treasurer and Secretary, each to hold office in accordance with the by-laws of Parent and of the Surviving Corporation and in accordance with the Amended and Restated Limited Liability Company Agreement of Merger Sub Two substantially in the form attached hereto as Exhibit B, as applicable, until his successor is duly elected or appointed and qualified.

     Section 1.6 Tax Consequences. It is intended by the parties that the Merger, together with the Second Merger, shall constitute a reorganization within the meaning of Section 368(a) of the Code and the parties shall not take income tax positions inconsistent with such qualification.

Article II.
Effect of Merger on Capital Stock

     Section 2.1 Conversion of Securities in the Merger. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Target, Merger Sub or any other Person:

          (a) Conversion of Merger Sub Capital Stock. Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time will automatically be canceled and converted into one fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

          (b) Cancellation of Certain Shares. Each share of Target Capital Stock held by Parent or Merger Sub, if any, or held in the treasury of Target, immediately prior to the Effective Time shall automatically be canceled, without any conversion thereof, and no payment shall be made with respect thereto.

          (c) Conversion of Target Common Stock.

               (i) Each share of Target Common Stock issued and outstanding immediately prior to the Effective Time (other than those held by Daniel M. Perlman and any Dissenting Shares) will be canceled and will, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive the Per Share Merger Consideration and each holder thereof will cease to have any rights with respect thereto, except the right to receive the Per Share Merger Consideration subject to and in accordance with Section 2.3.

               (ii) Each share of Target Common Stock issued and outstanding immediately prior to the Effective Time that is held by Daniel M. Perlman (other than Dissenting Shares) will be canceled and will, by virtue of the Merger and without any action on the part of Daniel M. Perlman, be converted into the right to receive the Perlman Per Share Merger Consideration and Daniel M. Perlman will cease to have any rights with respect thereto, except the right to receive the Perlman Per Share Merger Consideration subject to and in accordance with Section 2.3.

               (iii) Each Target Option Share issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares) will be canceled and will, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive the Target Optionholder Merger Consideration and each holder thereof will cease to have any rights with respect thereto, except the right to receive the Target Optionholder Merger Consideration subject to and in accordance with Section 2.3.

          (d) Conversion of Target Warrants. Each Target Warrant issued and outstanding immediately prior to the Effective Time will be canceled and will, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive the Warrant Per Share Merger Consideration for each share of Target Common Stock for which such Target Warrant is exercisable and each holder of a Certificate therefor will cease to have any rights with respect thereto, except the right to receive the Warrant Per Share Merger Consideration for each share of Target Common Stock for which such Target Warrant is exercisable subject to and in accordance with Section 2.3.

          (e) Conversion of Target Preferred Stock. Each share of Target Preferred Stock issued and outstanding immediately prior to the Effective Time will automatically be canceled, retired and cease to exist and (other than Dissenting Shares) will, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive (i) the Per Share Merger Consideration plus (ii) a cash payment equal to the amount of any accrued but unpaid dividends thereon (“Accrued Dividends”) and each holder thereof will cease to have any rights with respect thereto, except the right to receive the Per Share Merger Consideration and Accrued Dividends subject to and in accordance with Section 2.3.

          (f) Target Options. Each Target Option issued and outstanding immediately prior to the Effective Time will, as of the Effective Time, automatically be terminated and converted (the “Option Termination and Conversion”) into a Parent Option exercisable for that number of whole shares of Parent Common Stock equal to the product (rounded down to the nearest whole number of shares Parent Common Stock, with no cash being payable for any fractional share eliminated by such rounding) of the number of shares of Target Common Stock

that were issuable upon exercise of the Target Option immediately prior to the Effective Time, multiplied by 1.9947. The per share exercise price for the Parent Option shall be equal to the quotient (rounded up to the nearest whole cent) obtained by dividing the exercise price per share of Target Common Stock at which such Target Option was exercisable immediately prior to the Effective Time by 1.9947. The Parent Options shall be granted pursuant and subject to the Parent Option Plan and the applicable award agreement.

          (g) Solely for illustrative purposes, Schedule 2.1(g) attached hereto sets forth the conversion of shares of Target Capital Stock and Target Warrants in accordance with the terms of this Section 2.1 in respect of each holder thereof. In the event of any discrepancy or inconsistency between Exhibit C and this Section 2.1, the terms of this Section 2.1 shall prevail.

     Section 2.2 Dissenters’ Rights.

          (a) Notwithstanding anything in this Agreement to the contrary, shares of Target Capital Stock that are issued and outstanding immediately prior to the Effective Time and that are owned by any Target Shareholder who has not voted in favor of the Merger or consented thereto in writing and who has demanded payment of the fair value of such shares in accordance with Section 1575 of the PABCL (the “Dissenting Shares”) will not be converted into or be exchangeable for the right to receive the consideration set forth in Section 2.1 with respect thereto, unless and until such Target Shareholder fails to perfect, effectively withdraws or otherwise loses the right to payment of the fair value of such shares, and instead, such Target Shareholder will be entitled to payment of the fair value of such Dissenting Shares in accordance with the PABCL. If any such Target Shareholder fails to perfect or effectively withdraws or loses such payment rights, each share of Target Capital Stock held by such Target Shareholder will thereupon be deemed to have been converted into the right to receive and become exchangeable for, at the Effective Time, the consideration set forth in Section 2.1.

          (b) Target will give Parent (i) prompt notice of any demands for payment filed pursuant to Section 1575 of the PABCL, withdrawals of such demands and any other instruments served or delivered in connection with such demands pursuant to the PABCL and received by Target and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands under the PABCL. Target will not, except with the prior written consent of Parent, (a) make any payments with respect to any such demand or (b) settle any such demand.

     Section 2.3 Exchange of Certificates.

          (a) Exchange Procedures. An RPS Securityholder will have satisfied the “Delivery Requirements” if such RPS Securityholder (i) executes and delivers a counterpart signature page to this Agreement, (ii) executes and delivers a Letter of Transmittal (as defined below) and (iii) delivers original Certificates representing such RPS Securityholder’s Target Capital Stock and Target Warrants, if any, or an Affidavit of Loss to Parent. From and after the Effective Time, Parent shall have and make available a sufficient amount of cash and a sufficient number of shares of Parent Common Stock and New Parent Warrants for exchange in accordance with the terms and conditions of this Agreement. No RPS Securityholder shall be entitled to receive its share of the applicable Merger Consideration provided in Section 2.1 until it has satisfied the Delivery Requirements. Target shall use commercially reasonable efforts to

mail or deliver (or cause to be mailed or delivered) within fourteen (14) days after the date of this Agreement a letter of transmittal substantially in the form attached hereto as Exhibit C (the “Letter of Transmittal”) and a copy of the Information and Offering Memorandum to each RPS Securityholder that did not previously satisfy the Delivery Requirements. Target shall, upon receiving any original Letter of Transmittal, Certificate, Affidavit of Loss or other communication or correspondence concerning the Letter of Transmittal or the Merger, promptly inform Parent of the same and deliver such original to Parent (it being understood that in all cases Parent shall receive and hold the original of the Letter of Transmittal in escrow pending the Closing and the RPS Securityholders Committee shall receive and hold a copy of the Letter of Transmittal). From and after the Effective Time, Parent shall within three (3) Business Days after an RPS Securityholder has satisfied the Delivery Requirements (x) pay such RPS Securityholder in cash, by wire transfer of immediately available funds the amount of any cash to which such RPS Securityholder is entitled pursuant to Section 2.1 to the account(s) specified in such RPS Securityholder’s Letter of Transmittal and (y) deliver to such RPS Securityholder the number of shares of Parent Common Stock and New Parent Warrants to which such RPS Securityholder is entitled pursuant to Section 2.1 (if any). Until surrendered as contemplated by this Section 2.3, each Certificate shall be deemed upon and at any time after the Effective Time to represent only the right to receive the appropriate amount of the consideration without interest as provided in Section 2.1.

          (b) Transfer Restrictions. The shares of Parent Common Stock and the New Parent Warrants to be issued by Parent in connection with the Merger may not be transferred or resold thereafter, except in compliance with the terms of this Agreement and the other Ancillary Documents and following registration under the Securities Act or in reliance on an exemption from registration under the Securities Act. Shares of Parent Common Stock and the New Parent Warrants shall also be subject to the restrictions on transfer, sale and other disposition as set forth in the by-laws of Parent and in such agreements as may exist between Parent and its stockholders. In connection therewith, Parent shall be entitled to affix appropriate legends to the certificates representing the shares of Parent Common Stock and the New Parent Warrants issued in connection with the Merger.

          (c) No Further Ownership Rights. At the Effective Time, the stock transfer books of Target will be closed, and there will be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Target Capital Stock or Target Warrants that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for transfer or any other reason, they will be canceled and exchanged for the applicable portion of the Merger Consideration provided in Section 2.1.

          (d) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed, which shall be in form and substance reasonably satisfactory to Parent (an “Affidavit of Loss”), Parent will deliver in exchange for such lost, stolen or destroyed Certificate, the applicable portion of the Merger Consideration provided in Section 2.1 for each share of Target Capital Stock and each Target Warrant formerly evidenced by such Certificate, and such certificate shall then be canceled. Each Affidavit of Loss shall require the return of any original certificate located subsequent to the delivery of the applicable

portion of the Merger Consideration and the indemnification of Parent for any loss, cost, expense or damage related thereto.

     Section 2.4 Withholding Rights. Each of the Surviving Corporation, Parent, Merger Sub and the RPS Securityholders Committee shall be entitled to deduct and withhold from the consideration otherwise payable in connection with this Agreement to any RPS Securityholder such amounts as it is required pursuant to applicable Law to deduct and withhold with respect to Taxes; provided that the Surviving Corporation, Parent, Merger Sub or the RPS Securityholders Committee, as the case may be, promptly pays when due such amount deducted and withheld to the appropriate Governmental Authority for the account of such RPS Securityholder. To the extent that amounts are so withheld and paid, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the RPS Securityholder in respect of which such deduction and withholding was made.

     Section 2.5 Further Actions. If, at any time after the Effective Time, Parent or the Surviving Corporation shall consider or be advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either Merger Sub or Target acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement and the Merger, the officers and directors of Parent and the Surviving Corporation are hereby authorized to execute and deliver, in the name and on behalf of each of Merger Sub or Target or otherwise, all such deeds, bills of sale, assignments and assurances and to take and do, in the name and on behalf of each of Merger Sub or Target or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement and the Merger.

Article III.
Representations and Warranties Concerning Target

          Target hereby represents and warrants to Parent and Merger Sub that, except as set forth in the Disclosure Letter furnished by Target to Parent simultaneously with the execution hereof (the “Target Disclosure Letter”), the statements contained in this Article III are true, complete and correct as of the date hereof, and will be true and correct as of the Effective Time, except to the extent such representations and warranties are specifically made as of a particular date (in which case such representations and warranties are true, complete and correct as of such date).

     Section 3.1 Organization and Qualification. Target is a corporation duly incorporated and subsisting under the laws of Pennsylvania. Each of Target’s Subsidiaries is a business entity validly formed and organized in jurisdictions outside the United States as set forth in Section 3.1 of the Target Disclosure Letter. Target and each of its Subsidiaries has all requisite power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted. Target is in good standing, and Target and each of its Subsidiaries is duly qualified or licensed to do business, in each jurisdiction in which the nature of its business or its ownership or leasing of property requires such qualification, except for those jurisdictions in which the

failure to be so qualified or in good standing, individually or in the aggregate, has not had and would not reasonably be expected to have, a Target Material Adverse Effect. Section 3.1 of the Target Disclosure Letter sets forth a true, complete and correct list of all foreign jurisdictions in which Target or any of its Subsidiaries is so qualified or licensed.

     Section 3.2 Governing Documents; Corporate Records. Copies of the articles of incorporation and by-laws of Target, as currently in effect (collectively, the “Target Governing Documents”), and the articles of incorporation and by-laws or comparable organizational documents, each as currently in effect, for each of Target’s Subsidiaries (collectively, the “Subsidiary Governing Documents”), heretofore delivered to Parent are true, complete and correct copies of such instruments as in effect as of the date hereof. The Target Governing Documents and the Subsidiary Governing Documents are in full force and effect. Target is not in material violation of any provision of the Target Governing Documents, and none of Target’s Subsidiaries is in material violation of any provision of the Subsidiary Governing Documents applicable to it. The books and records, minute books, stock record books and other similar records of Target and each of its Subsidiaries, all of which have been delivered to Parent, are true, complete and correct in all material respects.

     Section 3.3 Corporate Power and Authority; Vote Required.

          (a) Target has all requisite corporate power and authority to execute and deliver this Agreement and each other document contemplated hereby to which Target is a party (each, a “Target Document” and collectively, the “Target Documents”). Subject to obtaining the Target Shareholder Approval, the execution and delivery by Target of this Agreement and each of the Target Documents, the performance by Target of its obligations hereunder and thereunder and the consummation by Target of the transactions contemplated hereby and thereby (including, without limitation, the Second Merger) have been duly authorized by all necessary corporate actions on the part of Target, and no other proceedings on the part of Target are necessary to authorize this Agreement or any of the Target Documents or to consummate the transactions contemplated hereby or thereby (including, without limitation, the Second Merger). This Agreement has been duly executed and delivered by Target and, assuming the due authorization, execution and delivery hereof by Parent and Merger Sub, constitutes legal, valid and binding obligations of Target, enforceable against Target in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar Laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity) (collectively, “Equitable Limitations”). Each of the Target Documents, assuming the due authorization, execution and delivery thereof by each other party thereto at the Closing, will constitute legal, valid and binding obligations of Target, enforceable against Target in accordance with their respective terms, except as such enforceability may be limited by Equitable Limitations.

          (b) The Target Board, at a meeting duly called and held prior to execution of this Agreement or by written consent in lieu of a meeting of the Target Board, unanimously adopted resolutions (i) approving and adopting this Agreement, the Merger, the Option Termination and Conversion and the other transactions contemplated by this Agreement and (ii) recommending that the Target Shareholders approve and adopt this Agreement.

          (c) The only vote of the holders of any class or series of Target Capital Stock necessary to approve this Agreement and the consummation of the Merger and the other transactions contemplated hereby is the affirmative vote, at a meeting duly called and held, or by written consent in lieu of such meeting, of (i) the holders of a majority of the outstanding shares of Target Common Stock and Target Preferred Stock, voting together as a single class on an as-converted to Target Common Stock basis, (ii) the holders of a majority of the outstanding shares of Target Series A Preferred Stock, voting together as a single class on an as-converted to Target Common Stock basis, and (iii) the holders of a majority of the outstanding shares of Target Series B Preferred Stock, voting together as a single class on an as-converted to Target Common Stock basis, (collectively, the “Target Shareholder Approval”), in accordance with the provisions of the Target Governing Documents and applicable Laws.

     Section 3.4 Capitalization.

          (a) As of the date hereof, the authorized capital stock of Target consists of 18,000,000 shares of Target Common Stock, of which there are 3,914,046 shares issued and outstanding; 5,401,960 shares of Target Series A Preferred Stock, all of which are issued and outstanding; and 910,000 shares of Target Series B Preferred Stock, of which there are 904,705 shares issued and outstanding.

          (b) As of the date hereof, the Target Capital Stock is held of record by the Persons and in the amounts set forth in Section 3.4(b) of the Target Disclosure Letter. Each of the issued and outstanding shares of Target Capital Stock: (i) has been offered and sold in material compliance with all applicable securities Laws; (ii) has been duly authorized and validly issued in material compliance with all applicable Laws and the provisions of the Target Governing Documents; (iii) is fully paid and nonassessable; and (iv) is free of preemptive rights. The amount of all accrued and unpaid dividends in respect of the Target Capital Stock is set forth in Section 3.4(b) of the Target Disclosure Letter.

     Section 3.22 Employee Benefit Plans.

          (a) Section 3.22(a) of the Target Disclosure Letter contains a true, correct and complete list of each deferred compensation, bonus, incentive compensation, stock purchase, stock option and other equity or equity-based compensation plan, program, agreement or

arrangement; each separation or termination pay, medical, surgical, hospitalization, life insurance and other “welfare plan,” fund or program (within the meaning of Section 3(1) of Employee Retirement Income Security Act of 1974, as amended (“ERISA”)); each profit-sharing, stock bonus or other “pension plan,” fund or program (within the meaning of Section 3(2) of ERISA); and each other material employee benefit plan, fund, program, agreement or arrangement, in each case, that is, or was within the past six (6) years, sponsored, maintained or contributed to or required to be contributed to by Target or by any trade or business, whether or not incorporated, that together with Target would be deemed a “single employer” within the meaning of Section 414(b), (c), (m) or (o) of the Code (each, an “ERISA Affiliate”), or to which Target or any ERISA Affiliate is party, whether written or oral, for the benefit of any current or former employee, officer, director or consultant of Target (collectively, “Target Benefit Plans”).

          (b) Neither Target nor any of its Subsidiaries, nor any ERISA Affiliate, has any commitment or formal plan, whether legally binding or not, to create any additional material employee benefit plan or modify or change, in any material way, any existing Target Benefit Plan that would affect any current or former employee, officer, director or consultant of Target or any of its Subsidiaries.

          (c) With respect to each Target Benefit Plan and Subsidiary Benefit Plan, Target has heretofore delivered to Parent a current, true, correct and complete copy (or, to the extent no such copy exists, an accurate written description) thereof (including any amendments thereto) and, to the extent applicable: (i) any related trust agreement or other funding instrument; (ii) the most recent IRS determination, opinion or notification letter and any pending application requesting issuance of a determination letter; (iii) any summary plan descriptions, summaries of material modifications or other reports and summaries required under ERISA or the Code; (iv) for the two most recent years for which such documents are available, the Form 5500 and attached schedules, audited financial statements, actuarial valuation reports and any related correspondence; (v) copies of any material documents and correspondence relating to any Target Benefit Plan received from or provided to the IRS of the United States Department of Labor; and (vi) all summaries furnished employees, officers and directors of Target or any of its Subsidiaries of all incentive compensation, bonus or other plans and fringe benefits for which a summary plan description is not available.

No Target Benefit Plan is a voluntary employees’ beneficiary association under Section 501(c)(9) of the Code.

          (d) Neither Target nor any ERISA Affiliate, sponsors, maintains, contributes to or has an obligation to contribute to, or has at any time within the last six (6) years sponsored, maintained, contributed to or had an obligation to contribute to, any “multiemployer plan,” as such term is defined in Section 3(37) or Section 4001(a)(3) of ERISA or comparable provisions of any other applicable Law; any “multiple employer plan,” as such term is defined in Treasury Regulation Section 1.413-2(a)(2); any “multiple employer welfare arrangement,” as such term is

          (e) Each Target Benefit Plan and each Subsidiary Benefit Plan has been operated and administered in all material respects in accordance with its terms and applicable Law, including but not limited to ERISA and the Code to the extent applicable, and all contributions required to be made under the terms of any of the Target Benefit Plans and each Subsidiary Benefit Plan as of the date hereof have been timely made or, if not yet due, have been properly reflected in the Target Financial Statements except for any failure to do so which would not result in any material Liability to Target or any of its Subsidiaries. All premiums or other payments required for applicable insurance coverage for all periods ending on or before the Effective Time have been paid or accrued for each Target Benefit Plan and each Subsidiary Benefit Plan.

          (f) Except for benefits provided under the Material Employment Agreements, no Target Benefit Plan or Subsidiary Benefit Plan provides medical, surgical, hospitalization, death or similar benefits (whether or not insured) for employees or former employees of Target or any of its Subsidiaries for periods extending beyond their retirement or other termination of service, other than coverage mandated by applicable Law.

          (g) Except as described in Section 3.22(g) of the Target Disclosure Letter, the consummation of the transactions contemplated by this Agreement (including, without limitation, the Second Merger), either alone or in combination with another event, will not: (i) entitle any current or former employee, director, officer or consultant of Target or any of its Subsidiaries to severance pay, unemployment compensation, loan forgiveness or any other payment; (ii) except as provided in this Agreement, accelerate the time of payment or vesting, or increase the amount of, any compensation or benefits due any such employee, director, officer or consultant, including without limitation under any Target Benefit Plan or Subsidiary Benefit Plan; or (iii) prevent Target or any of its Subsidiaries from amending or terminating any Target Benefit Plan or Subsidiary Benefit Plan.

          (i) Each Target Benefit Plan that is a “nonqualified deferred compensation plan” within the meaning of Section 409A of the Code has been operated, in all material respects, in good faith compliance with Section 409A of the Code and IRS Notices 2005-1, 2006-4 and 2006-79.

          (j) Except as set forth in Section 3.22(j) of the Target Disclosure Letter, Target does not sponsor or contribute to or have any Liability with respect to any employee benefit plan, program or arrangement that provides or provided benefits to employees who perform or performed services for Target outside of the United States.

          (k) There is no agreement, contract, plan or arrangement to which Target or any of its Subsidiaries is a party that may result, separately or in the aggregate, in the payment of any amount by Target or any of its Subsidiaries that is not deductible under Section 404 of the Code or that may be an “excess parachute payment” within the meaning of Section 280G of the Code and no action by Target or any of its Subsidiaries, whether pursuant to this Agreement or otherwise, shall result in the making of any such payment.

     Section 3.23 No Illegal Payments. To the Knowledge of Target, neither Target nor any of its Subsidiaries, nor any of their respective officers, directors or agents, nor any other Person acting on behalf of Target or any of its Subsidiaries, nor any Affiliate, has: (i) used any corporate or other funds of Target or any of its Subsidiaries for unlawful contributions, payments, gifts or entertainment, or made any unlawful expenditures relating to political activity to government officials or others, or established or maintained any unlawful or unrecorded funds, in violation of any applicable Law; (ii) made any payment for the account or benefit, or using funds, of Target or any of its Subsidiaries in violation of applicable Law to foreign or domestic government officials or employees or to foreign or domestic political parties or campaigns or violated any provision of the Foreign Corrupt Practices Act of 1977, as amended; (iii) accepted or received any unlawful contributions, payments, expenditures or gifts; or (iv) made any false or fictitious entries in the books and records of Target or any of its Subsidiaries.

provided, however, that the Parent Indemnitors shall have no obligation to indemnify any Target Indemnitee to the extent any such Losses are attributable to statements or information supplied by Target concerning Target or its financial condition or operations for inclusion or incorporation by reference in the “Letter from the Chairman of Cross Shore – Background to RPS,” “Risk Factors – Risks Related to RPS/The Biopharmaceutical Outsourcing Industry,” “Information on RPS/The Enlarged Group – Information on RPS” and “Financial Information on RPS” sections of the Readmission Document or in such other sections of the Readmission Document containing statements or information supplied by Target concerning Target or its financial condition or operations for inclusion or incorporation by reference in such other sections, or any amendments or supplements to such sections mutually agreed to by Parent and Target.

     Section 9.4 Survival.

          (a) The representations and warranties of (i) Target made in or pursuant to this Agreement and the closing certificate to be delivered pursuant to Section 7.2(c) and (ii) the RPS Securityholders made in or pursuant to this Agreement will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby for a period of six (6) months; provided, however, that: (a) the representations and warranties set forth in Sections 3.3 (Corporate Power and Authority; Vote Required), 3.4 (Capitalization), 3.13 (Environmental Matters), 3.14(a) (Title to Assets; Real Estate), 3.17 (Private Information), 3.19 (Taxes), 3.22 (Employee Benefit Plans), 4.2 (Authorization) and 4.4 (Target Capital Stock and Target Warrants) will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby for a period of two (2) years; and (b) any representation or warranty the violation or alleged violation of which is made the basis of a Claim for indemnification pursuant to Section 9.1(a) or Section 9.2(a) will survive until such Claim is finally resolved if Parent notifies the RPS Securityholders Committee in writing of such Claim in reasonable detail prior to the date on which such representation or warranty would otherwise expire hereunder. Notwithstanding the foregoing, Parent shall not be entitled to pursue a claim for indemnification against the RPS Securityholders Committee in respect of the breach of any representation or warranty contained in this Agreement after the second anniversary of the Closing.

          (b) The representations and warranties of Parent and Merger Sub made in or pursuant to this Agreement and the closing certificate to be delivered pursuant to Section 7.3(c) will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby for a period of six (6) months; provided, however, that the representations and warranties set forth in Sections 5.3 (Corporate Power and Authority; Vote Required) and 5.4 (Capitalization) will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby for a period of two (2) years; and (b) any representation or warranty the violation or alleged violation of which is made the basis of a Claim for indemnification pursuant to Sections 9.3(a) will survive until such Claim is finally resolved if the RPS Securityholders Committee notifies Parent in writing of such Claim in reasonable detail prior to the date on which such representation or warranty would otherwise expire hereunder.

          (c) The covenants and agreements of each party made in or pursuant to this Agreement will survive until fully performed or fulfilled.

     Section 9.5 Limitations. Absent fraud or intentional misrepresentation, after the Closing, the aggregate amount of indemnifiable Losses for which the Target Indemnitors shall be liable pursuant to Section 9.1(a) shall not exceed $5,000,000 (the “Cap”); provided, however, that the Target Indemnitors shall not be liable pursuant to Section 9.1(a) (i) for Losses in respect of any single breach if the amount of such Losses does not exceed a $20,000 minimum value per claim (the “Threshold”), it being understood that the amount of two (2) or more claims reasonably related in subject matter or arising out of the same facts or circumstances shall be combined for purposes of determining whether the Threshold has been met (any Losses in respect of a breach which do not meet the Threshold being “Disregarded Losses”), and (ii) until the aggregate amount of all Losses (not including any Disregarded Losses) exceeds $500,000 (the “Basket”), in which event the Parent Indemnitees shall be entitled to recover such Losses (other than Disregarded Losses) to the extent in excess of the Basket, but not exceeding the Cap. The limitations in this Section 9.5 shall not apply to any breach by Target of the representations set forth in Section 3.4(a). Absent fraud or intentional misrepresentation, after the Closing, the Parent Indemnitees’ exclusive right to monetary damages shall be solely for indemnification pursuant to this Article IX and subject to the applicable limitations contained herein; provided, however, that this Section 9.5 in no way limits any party’s rights to applicable equitable remedies. For the avoidance of doubt, the limitations contained in this Section 9.5 shall not apply in respect of claims for indemnification made pursuant to Section 9.2. The computation of the amount of any Loss shall be done on an after-tax basis that takes into account the tax benefits, if any, that result from the Loss and the event giving rise to the Loss and the tax costs, if any, that result from any indemnification payment under this Agreement. All indemnification payments under this Agreement shall, except as otherwise required by Federal income tax law, be treated for Federal income tax purposes as an adjustment to the Merger Consideration provided to the RPS Securityholders. For purposes of determining whether there has been any misrepresentation or breach of a representation or warranty for purposes of Section 9.1, and for purposes of determining the amount of Losses resulting therefrom, all qualifications or exceptions therein relating to or referring to the terms “material”, “materiality”, “in all material respects”, “Material Adverse Effect” or any similar term or phrase shall be disregarded, it being the understanding of the parties that for purposes of determining liability under Section 9.1, the representations and warranties of the parties contained in this Agreement shall be read as if such terms and phrases were not included in them.

     Section 9.6 Third Party Claims.

          (a) The following procedures shall be applicable with respect to indemnification for third party Claims. Promptly after receipt by any Parent Indemnitee or Target Indemnitee (each, an “Indemnified Party”), as applicable, of notice of the commencement or assertion of any Claim by a third party (whether by legal process or otherwise), against which Claim the Target Indemnitors or the Parent Indemnitors (each, an “Indemnifying Party”), as applicable, are, or may be, required to indemnify such Indemnified Party, shall, if a Claim thereon is to be, or may be, made against the Indemnifying Party, notify the RPS Securityholders Committee (if any Target Indemnitor is an Indemnifying Party) or Parent (if any Parent Indemnitor is an Indemnifying Party), as applicable, in writing of the commencement or

assertion thereof and give the RPS Securityholders Committee or Parent, as applicable, a copy of such Claim, process and all legal pleadings. The Indemnifying Party shall have the right to: (i) participate in the defense of such Claim with counsel of reputable standing; and (ii) assume the defense of such Claim by agreeing in writing to assume such defense within ten (10) days of transmittal of the notice of the Claim by such Indemnified Party, unless: (a) such Claim may result in criminal proceedings, injunctions or other equitable remedies in respect of such Indemnified Party or its business; (b) such Claim may result in Liabilities that, taken with other then existing Claims under this Article IX, would not be fully indemnified hereunder or exceed the Cap, if applicable; (c) the Indemnifying Party fails to vigorously prosecute or defend such Claim, in which case such Indemnified Party shall have the right to assume the defense and shall have the full right to defend such Claim, or (d) such Claim is with respect to Taxes, in which case the Target Indemnitors shall have the right to assume the defense or settlement of such third party Claim only if it relates solely to Taxes of Target or its Subsidiaries for a taxable year or other taxable period ending on or before the Closing Date.

          (b) The parties shall reasonably cooperate in the defense of any third party Claim. In the event that the Indemnifying Party assumes or participates in the defense of such third party Claim as provided herein, the Indemnified Party shall make available to the Indemnifying Party all relevant records and take such other action and sign such documents as are reasonably necessary to defend such third party Claim in a timely manner. No Indemnifying Party in the defense of any such Claim, shall, except with the consent of any Indemnified Party consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all Liability with respect to such Claim or that requires any admission of Liability by any Indemnified Party. In addition, with respect to a third party Claim for Taxes, the Target Indemnitors shall not consent to entry of any judgment or enter into any settlement of (or otherwise compromise) such Claim without the written consent of Parent, which consent shall not be unreasonably withheld or delayed. In the event that the Indemnifying Party does not exercise its right to assume the defense of any matter for which it is entitled to assume as set forth in this Section 9.6, the Indemnified Party shall have the full right to defend such Claim. In the event that an Indemnified Party assumes the defense of any Claim, the Indemnifying Party shall be entitled to participate in the defense of such Claim at its own expense.

          (c) Prior to paying or settling any Claim against which the Indemnifying Party is, or may be, obligated under this Agreement to indemnify any Indemnified Party, such Indemnified Party must first: (i) supply the RPS Securityholders Committee or Parent, as applicable, with a copy of a final court judgment or decree holding such Indemnified Party liable on such Claim; or (ii) receive written Approval to the terms and conditions of such settlement from the RPS Securityholders Committee or Parent, as applicable, which Approval shall not be unreasonably withheld or delayed; provided, however, that no written Approval is required from the RPS Securityholders Committee or Parent as to any third party Claim: (a) that results solely in injunctions or other equitable remedies in respect of the Indemnified Party or its business; or (b) that settles Liabilities, or portions thereof, that are not subject to indemnification hereunder.

          (d) Any Indemnified Party shall have the right to employ its own counsel with respect to any Claim, and the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless: (i) the employment of such counsel shall have been authorized in

writing by the RPS Securityholders Committee or by Parent, as applicable, in connection with the defense of such Claim; (ii) the RPS Securityholders Committee or Parent, as applicable, shall not have employed counsel in the defense of such Claim after twenty (20) days notice and only if such Indemnified Party’s position has been materially prejudiced by the failure of the Indemnifying Party to assume the defense thereof; or (iii) such Indemnified Party shall have reasonably concluded that there may be defenses available to it that are contrary to, or inconsistent with, those available to the Indemnifying Party; and in any of the foregoing events such reasonable fees and expenses shall be borne by the Indemnifying Party.

     Section 9.7 Payment of Indemnification Claims.

          (a) Subject to the limitations set forth in this Article IX, Indemnifying Parties shall be entitled to pay or reimburse Indemnified Parties for Losses in the form of Parent Common Stock. For purposes of this Section 9.7, the value of each share of Parent Common Stock shall be deemed to be the average of the closing sale price of Parent Common Stock as quoted on the AIM (or any successor market or index) for the ten (10) consecutive trading days ending the trading day that is three (3) trading days preceding the day the indemnification claim is paid.

          (b) If the Indemnifying Parties are the Target Indemnitors, liability for the applicable Losses shall be allocated and shared among such Target Indemnitors in accordance with each such Target Indemnitor’s Proportionate Share.

          (c) If the Indemnifying Parties are the Parent Indemnitors, the payment for the applicable Losses shall be allocated and shared among the Target Indemnitees in accordance with each such Target Indemnitee’s Proportionate Share.

     Section 9.8 RPS Securityholders Contribution.

          (a) Each RPS Securityholder other than an Exercising Target Optionholder or holders of Dissenting Shares (each a “Participating Securityholder,” and collectively, the “Participating Securityholders”) agrees that it shall be responsible for and agrees to contribute and promptly pay to the RPS Securityholders Committee, an amount equal to (x) each and every amount due and payable in respect of any obligations of the RPS Securityholders pursuant to this Agreement, including, without limitation, indemnification obligations pursuant to Section 9.1 and related costs and expenses, and each and every amount incurred by the RPS Securityholders Committee in carrying out its duties and responsibilities as the RPS Securityholders Committee under this Agreement and the transactions contemplated hereby (not including any Individual Liabilities, “Shared Liabilities”), multiplied by (y) such RPS Securityholder’s Proportionate Share. Notwithstanding the foregoing, any and all obligations in respect of a breach by any RPS Securityholder of a representation, warranty, covenant or agreement made by such RPS Securityholder solely as to himself, herself or itself, as the case may be, under this Agreement (including indemnification obligations pursuant to Section 9.2 of this Agreement) or in any other agreement to which such RPS Securityholder is or becomes a party, shall be the sole and individual obligations of such RPS Securityholder, and Losses and related liabilities, costs and expenses resulting from such breach by such RPS Securityholder shall not be subject to

contribution by the other RPS Securityholders pursuant to this Agreement (“Individual Liabilities”), or be payable from the Deposit (as defined below).

          (b) At the Closing, Parent shall deduct from the portion of the Merger Consideration payable to the Participating Securityholders (i) cash in the aggregate amount of $250,000 (the “Cash Deposit”) and pay such Cash Deposit to the RPS Securityholders Committee to be held and used in accordance with this Agreement, and (ii) 1,500,000 shares of Parent Common Stock (the “Stock Deposit,” and together with the Cash Deposit, the “Deposit”) and deposit such Stock Deposit with the Escrow Agent to be held and disbursed in accordance with the Escrow Agreement.

          (c) Each Participating Securityholder shall be deemed to have contributed its Proportionate Share of the Cash Deposit and the Stock Deposit out of the portion of the Merger Consideration payable to such Participating Securityholder. Each Participating Securityholder authorizes and consents to the deduction by Parent from, and hereby directs Parent to deduct from, such Participating Securityholder’s portion of the Merger Consideration an amount of cash equal to such Participating Securityholder’s Proportionate Share of the Cash Deposit and a number of shares of Parent Common Stock equal to such Participating Securityholder’s Proportionate Share of the Stock Deposit. Each Participating Securityholder shall take all such actions and execute and deliver all such documents as are reasonably necessary or requested by the RPS Securityholders Representative Committee or Parent in order to ensure the delivery of the Deposit to the RPS Securityholders Committee and/or the Escrow Agent, as applicable, in accordance with this Agreement and to give effect to, confirm, or otherwise in furtherance of the provisions of this Section 9.8.

          (d) (i) The Stock Deposit shall be held in escrow pursuant to the terms of the Escrow Agreement. The Stock Deposit shall be the sole and exclusive source for the payment and satisfaction of, and the sole recourse of the Parent Indemnitees with respect to, any obligations of the Target Indemnitors to Parent Indemnitees pursuant to Section 9.1(a). The maximum aggregate value of the shares of Parent Common Stock that may be released from the Stock Deposit to Parent Indemnitees in satisfaction of indemnifiable Losses under Section 9.1(a) shall not exceed the Cap (for purposes of determining the aggregate value of the shares of Parent Common Stock released in satisfaction of indemnified Losses, each such share of Parent Common Stock shall have the value ascribed to such share of Parent Common Stock for purposes of determining the number of shares of Parent Common Stock required to satisfy the applicable Losses, determined in accordance with Section 9.7(a)). If and when there are no remaining shares of Parent Common Stock held in the Stock Deposit, Parent Indemnitees shall have no further recourse against any Target Indemnitors with respect to Section 9.1(a). For the avoidance of doubt, the limitations contained in this Section 9.8 shall not apply in respect of claims for indemnification made pursuant to Section 9.2.

               (ii) The Stock Deposit shall terminate on the earliest to occur of (x) the second anniversary of the Closing Date, (y) the date as of which the aggregate value of the shares of Parent Common Stock released from the Stock Deposit to Parent Indemnitees in satisfaction of indemnifiable Losses equals the Cap, or (z) the date as of which there are no shares of Parent Common Stock remaining in the Stock Deposit.

          (e) (i) The Cash Deposit shall be held by the RPS Securityholders Committee as the initial source for effecting the payment and discharge of Shared Liabilities other than those required to be satisfied out of the Stock Deposit. The RPS Securityholders Committee shall, and the Participating Securityholders hereby authorize and direct the RPS Securityholders Committee to, use the Cash Deposit to pay and discharge Shared Liabilities (to the extent not required to be satisfied out of the Stock Deposit) in its discretion. To the extent cash in excess of the Cash Deposit is required to satisfy Shared Liabilities (other than Shared Liabilities required to be satisfied out of the Stock Deposit), the Participating Securityholders shall each pay their respective Proportionate Share of such excess cash to the RPS Securityholders Committee in immediately available funds subject to and in accordance with paragraph (f) of this Section 9.8. Nothing herein shall be construed to release any Participating Securityholder from its responsibility to contribute for Shared Liabilities (other than Shared Liabilities required to be satisfied out of the Stock Deposit) in the event the Cash Deposit is insufficient to pay and discharge in full all such Shared Liabilities.

               (ii) The RPS Securityholders Committee shall hold the Cash Deposit for a period ending on the second anniversary of the Closing Date (the “Initial Term”), or such longer period as the RPS Securityholders Committee deems to be necessary to resolve claims for indemnification pursuant to Section 9.1 of this Agreement which remain outstanding after such date (together with the Initial Term, the “Term”), subject to the terms and conditions of this Agreement.

               (iii) The Cash Deposit shall be held in an account with an institution as determined by the RPS Securityholders Committee. The RPS Securityholders Committee shall have no obligation to invest the Cash Deposit. No interest shall be paid on the Cash Deposit.

               (iv) As promptly as is reasonably practicable after the expiration of the Initial Term, the RPS Securityholders Committee shall return or cause to be returned to the Participating Securityholders, in accordance with their respective Proportionate Shares, the balance of the Cash Deposit, less such portion of the Cash Deposit that the RPS Securityholders Committee determines in good faith to withhold pending resolution of any outstanding claims relating to Shared Liabilities. The RPS Securityholders Committee shall return to the Participating Securityholders (in accordance with their respective Proportionate Shares) the balance, if any, of any portion of the Cash Deposit withheld in respect of outstanding claims, as promptly as reasonably practicable after all such claims have been fully and finally resolved.

          (f) Whenever any amount shall be due and payable by any Participating Securityholder under this Agreement, the RPS Securityholders Committee shall promptly send notice thereof in writing, by facsimile transmission, recognized overnight delivery service, regular mail, electronic mail or hand delivery, to such Participating Securityholder at the address for such Participating Securityholder as set forth in his, her or its Letter of Transmittal, or such other address as such Participating Securityholder shall specify in a written notice given to the RPS Securityholders Committee in accordance with Section 10.1. Each such notice shall specify the aggregate amount of the applicable Shared Liabilities and the portion thereof payable by the Participating Securityholder. Each Participating Securityholder shall pay, in accordance with the payment instructions contained in such notice, to the RPS Securityholders Committee within five

(5) days after receipt of said notice the amount specified to be paid by such Participating Securityholder in said notice.

          (g) The RPS Securityholders Committee shall have no liability to any RPS Securityholders for any acts or omissions of the RPS Securityholders Representative Committee in connection with this Section 9.8, except to the extent expressly provided in Section 6.11.

          (h) The provisions of this Section 9.8 are intended solely to govern certain agreements among the RPS Securityholders and between the RPS Securityholders and the RPS Securityholders Committee. Nothing in this Section 9.8 shall be construed to limit in any way any of the obligations or liabilities of any RPS Securityholder under any other Section of this Agreement or any other Ancillary Document. Other than delivering the Cash Deposit to the RPS Securityholders Committee and the Stock Deposit to the Escrow Agent pursuant to Section 9.8(b), or taking such other actions as reasonably directed in writing by the RPS Securityholders Committee, Parent and Merger Sub shall have no liability or obligation of any kind under this Section 9.8.
