AGREEMENT AND PLAN OF MERGER, dated as of January 19, 2007 (this “Agreement”), by and among Healthcare Acquisition Corp., a Delaware corporation (“Parent”), PAI Acquisition Corp., a Delaware corporation and a direct, wholly-owned subsidiary of Parent (“Merger Sub”), and PharmAthene, Inc., a Delaware corporation (“Company”).

WITNESSETH:

WHEREAS, the respective Boards of Directors of Parent and Company have determined that it is advisable and in the best interests of each corporation and its stockholders that Parent and Company engage in a business combination in order to advance the long-term strategic business interests of Parent and Company; and

WHEREAS, in furtherance of such determination, Parent and Company desire to engage in a business combination transaction by means of a merger pursuant to which Merger Sub, a direct, wholly-owned subsidiary of Parent formed solely for the purpose of effecting the merger, will merge with and into Company as a result of which Company will be the surviving corporation and a direct, wholly-owned subsidiary of Parent; and

WHEREAS, in furtherance of such desire, the respective Boards of Directors of Parent, Merger Sub and Company have adopted or approved this Agreement, pursuant to which, subject to the terms and conditions hereof and in accordance with the General Corporation Law of the State of Delaware, Merger Sub will be merged with and into Company with Company being the surviving corporation (the “Merger”); and

WHEREAS, prior to or concurrently with the execution of this Agreement, the holders of a Requisite Majority of the Company Capital Stock (each as defined herein) have executed or are executing an Allocation Agreement (as defined herein), pursuant to which they, among other things, are agreeing to the allocation of the Merger Consideration (as defined herein) as set forth therein;

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements of the parties set forth in this Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

THE MERGER

1.1. Defined Terms. All terms not otherwise defined throughout this Agreement shall have the meanings ascribed to such terms in Article X of this Agreement.

1.2. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the Delaware General Corporation Law (the “DGCL”), Merger Sub shall be merged with and into Company at the Effective Time (as defined in Section 1.4). Upon consummation of the Merger, the separate corporate existence of Merger Sub shall cease and Company shall continue as the surviving corporation (the “Surviving Corporation”).

1.3. Closing. Subject to the terms and conditions hereof, the closing of the Merger and the transactions contemplated by this Agreement (the “Closing”) will take place on or before the third Business Day after the satisfaction or waiver (subject to applicable law) of the conditions set forth in Article VI (other than any such conditions which by their terms cannot be satisfied until the Closing, which shall be required to be so satisfied or waived (subject to applicable law) on the Closing Date) unless another time or date is agreed to in writing by the parties hereto (the actual time and date of the Closing being referred to herein as the “Closing Date”). The Closing shall be held at the offices of Ellenoff ▇▇▇▇▇▇▇▇ & Schole, LLP, ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, unless another place is agreed to in writing by the parties hereto.

1.4. Effective Time. At the Closing, the parties shall file a certificate of merger (the “Certificate of Merger”) in such form as is required by and executed in accordance with the relevant provisions of the DGCL. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such subsequent time as Parent and Company shall agree and as shall be specified in the Certificate of Merger (the date and time that the Merger becomes effective being referred to herein as the “Effective Time”).

1.5. Effects of the Merger. At and after the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all of the property, rights, privileges, powers and franchises of Company and Merger Sub shall be vested in the Surviving Corporation, and all debts, liabilities and duties of Company and Merger Sub shall be the debts, liabilities and duties of the Surviving Corporation.

1.6. Certificate of Incorporation. At the Effective Time and without any further action on the part of Company or Merger Sub, the certificate of incorporation of Company, as in effect immediately prior to the Effective Time, shall be the certificate of incorporation of the Surviving Corporation, and thereafter shall continue to be the certificate of incorporation until changed or amended as provided therein and under applicable law. Notwithstanding the foregoing, the certificate of incorporation of Company shall be amended and restated as of the Effective Time to provide for the changing of the name of Company and to eliminate all classes of equity securities other than common stock.

1.7. Bylaws. At the Effective Time and without any further action on the part of Company and Merger Sub, the bylaws of Company, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation, and thereafter shall continue to be the bylaws until changed or amended or repealed as provided therein, in the certificate of incorporation of the Surviving Corporation and under applicable law.

1.8. Directors and Officers.

(a) Members of Board of Directors. From and after the Effective Time, the members of the Board of Directors of both the Parent and the Surviving Corporation shall consist of ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, M.D., ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇ St. ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇ ▇▇▇▇▇▇, each to serve until his or her successor is elected and qualified or until his or her earlier death, resignation or removal. If at or after the Effective Time a vacancy shall exist in the Board of Directors of Parent and the Surviving Corporation, such vacancy may thereafter be filled in the manner provided by law, the certificate of incorporation and bylaws of Parent and the Surviving Corporation, as the case may be.

-2-

(b) Officers of Parent and Surviving Corporation. From and after the Effective Time, the officers of Parent and of the Surviving Corporation shall be elected by the Board of Directors of each entity provided, however, that ▇▇▇▇▇ ▇▇▇▇▇▇ shall be elected Chief Executive Officer of each such entity to serve until his successor is elected and qualified or until his earlier death, resignation or termination.

1.9. Effect of Merger on Company Capital Stock and Options; Merger Consideration. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and this Agreement and without any action on the part of Merger Sub, Company or the holder of any shares of Company Capital Stock (as defined in clause (b)(i) below) the following shall occur:

(a) Company Treasury Shares. All shares of Company Common Stock (as defined in clause (b)(i) below) that are held by Company as treasury stock (the “Company Treasury Shares”) or owned by Merger Sub, Parent or any direct, or indirect, wholly-owned subsidiary of Parent immediately prior to the Effective Time shall be canceled and shall cease to exist and no cash, Parent Common Stock (as defined in clause (b)(i) below) or other consideration shall be delivered in exchange therefor.

(b) Company Capital Stock.

(i) The shares of common stock of Company, $.001 par value (the ‘‘Company Common Stock’’), Series A Convertible Preferred Stock of Company, $.001 par value (the “Company Series A Preferred Stock”‘), Series B Convertible Preferred Stock of Company, $.001 par value (the “Company Series B Preferred Stock”), and Series C Convertible Preferred Stock of Company, $.001 par value (the “Company Series C Preferred Stock” and together with the Company Series A Preferred Stock, and the Company Series B Preferred Stock, the “Company Preferred Stock” and together with the Company Common Stock collectively referred to as“Company Capital Stock”, outstanding immediately prior to the Effective Time, shall be deemed canceled and converted into the right to receive the merger consideration comprised of: (y) 12,500,000 shares of Common Stock of Parent, $.0001 par value (“Parent Common Stock”), subject to upward adjustment pursuant to clause (c) below (the “Stock Consideration”) and (z) to the extent applicable, the Milestone Payments (as defined in Article X).

-3-

(ii) The specific ratio of exchange for the Company Common Stock for shares of Parent Common Stock (“Share Exchange Ratio”) as well as the specific Merger Consideration to be received by the holders of other classes of Company Capital Stock have been prepared by Company in accordance with the Recapitalization and Proceeds Allocation Agreement, dated the date of this Agreement, entered into by and among Company and the holders of a Requisite Majority of the Company Common Stock and Company Preferred Stock and the holders of the PharmAthene Notes (as defined below) (the “Allocation Agreement”), and are set forth on Schedule 1.9(b)(i) and will be confirmed or adjusted by the Company, as applicable, at Closing. The holders of Company’s issued and outstanding secured 8% convertible notes and the Subsidiary’s issued and outstanding secured 8% convertible note, collectively with an aggregate principal amount of $11,800,000 (collectively the “PharmAthene Notes”) shall exchange such notes for 8% Convertible Notes of Parent in the aggregate principal amount of $12.5 million (the “Note Consideration”) in substantially the form of Exhibit A attached hereto, pursuant to the Note Exchange Agreement, as further described in Section 6.3(j)(viii) below. Parent shall issue the Merger Consideration (as defined in the next sentence) in accordance with the Allocation Agreement. For purposes of this Agreement, the term “Merger Consideration” shall be deemed to include (a) the Stock Consideration; (b) the Milestone Payments and (c) the Note Consideration.

(i) To the extent that the stockholders of Parent owning more than 5% of the outstanding Parent Common Stock exercise their conversion rights as set forth in Section 6.1(b), the number of shares of Parent Common Stock comprising the Stock Consideration shall be adjusted upward by the product of (x) the number (as a percentage) that is the difference between the percentage of Parent Common Stock that is converted and 5% and (y) 2.25 million.

(ii) To the extent that there are Outstanding Employee Options (as defined in clause (d) below) there shall be no increase in the number of shares of Stock Consideration being issued, but the number of shares of Parent Common Stock issued at the Closing as part of the Stock Consideration shall be adjusted downward by an amount equal to the number of shares necessary to reserve for issuances under any Outstanding Employee Options in accordance with the Allocation Agreement.

(iii) Except for any warrants issued pursuant to a Company Subsequent Issuance (as defined in clause (c)(iv) below), the terms of which shall be subject to the provisions of clause (c)(iv) below, to the extent that there are outstanding warrants to purchase shares of Company Common Stock (“Company Warrants”), there shall be no increase in the number of shares of Stock Consideration being issued, but the number of shares of Parent Common Stock issued at the Closing as part of the Stock Consideration shall be adjusted downward by an amount equal to the number of shares necessary to reserve for issuances under any outstanding Company Warrants in accordance with the Allocation Agreement.

-4-

(iv) If, prior to the date that the Proxy Statement (as defined in Section 4.1) to be filed by Parent pursuant to Article IV hereof is approved by the SEC, Company issues additional shares of its Common Stock (or any equity or debt securities convertible into Common Stock) for cash consideration of up to $5 million (subject to the limitation that the securities of the Company issued to the purchasers (the “Subsequent Issuance Securities”) thereof will not convert into more than 625,000 shares of Parent Common Stock in the Merger, which number of shares would be proportionately reduced to reflect the sale of less than $5 million) (a “Company Subsequent Issuance”), then the number of shares of Parent Common Stock comprising the Stock Consideration shall be increased by the number of shares of Parent Common Stock into which the Subsequent Issuance Securities will be converted in the Merger.

(d) Options.

(i) Immediately after the Effective Time, all options to purchase Company Common Stock then outstanding (individually, an “Outstanding Employee Option,” and collectively, the “Outstanding Employee Options”) under the PharmAthene, Inc. 2002 Long-Term Incentive Plan (as amended, the “Option Plan”) or issued under any other agreement shall, whether vested or unvested, be assumed by Parent. Each such Outstanding Employee Option so assumed by Parent under this Agreement shall continue to have, and be subject to, the same terms and conditions set forth in the Option Plan, option agreements thereunder and other relevant documentation in existence immediately prior to the Effective Time, except that each such Outstanding Employee Option will be converted into an option to purchase that number of shares of Parent Common Stock calculated by multiplying such Outstanding Employee Option by the Share Exchange Ratio and rounding down to the nearest whole share of Parent Common Stock. The per-share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Outstanding Employee Option will be equal to the quotient determined by dividing the exercise price per share of Company Common Stock at which such Outstanding Employee Option was exercisable immediately prior to the Effective Time by the Share Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent.

(ii) Parent shall establish a new option plan containing terms no less favorable to holders of Outstanding Employee Options as applicable to the Outstanding Employee Options and Parent shall reserve for issuance under such plan a sufficient number of shares of Parent Common Stock for delivery upon exercise of Outstanding Employee Options assumed by Parent under this Agreement plus an additional 3,000,000 shares.

(iii) Unless provided for in the option grant or Option Plan of Company, the vesting of each Outstanding Employee Option will not automatically accelerate pursuant to its terms as a result of, or in connection with, the transactions contemplated hereby. Company shall ensure that none of its Board of Directors nor any committee thereof nor any other body or person within its control shall take any discretionary action so as to cause the vesting of any Outstanding Employee Option which does not vest by its terms prior to the Effective Time.

-5-

1.10. Merger Sub Stock. Each share of common stock, par value $.0001, of Merger Sub outstanding immediately prior to the Effective Time shall be deemed canceled and converted into and shall represent the right to receive one share of common stock, $.01 par value, of the Surviving Corporation (the “Surviving Common Stock”).

1.11. Dissenters’ Rights. Notwithstanding Section 1.9(b)(i) and (ii), any shares of Company Common Stock outstanding immediately prior to the Effective Time and held by a person who has not voted in favor of the Merger and who has properly demanded in writing appraisal for such shares in accordance with Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration or be entitled to cash in lieu of fractional shares of Parent Common Stock or any dividends or other distributions pursuant to this Article I unless and until the holder thereof (“Dissenting Stockholder”) shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal of such shares of Company Common Stock held by such holder under Section 262 of the DGCL, and any Dissenting Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL with respect to shares of Company Common Stock owned by such Dissenting Stockholder. If any person who otherwise would be deemed a Dissenting Stockholder shall have failed to properly perfect or shall have effectively withdrawn or lost the right to dissent with respect to any shares of Company Common Stock, such shares of Company Common Stock shall thereupon be treated as though such shares of Company Common Stock had been converted into the right to receive the Merger Consideration pursuant to Section 1.9 hereof. Company shall give Parent (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands and any other instruments served pursuant to applicable law received by Company relating to stockholders’ rights of appraisal and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands for appraisal under the DGCL. Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisals of Dissenting Shares, offer to settle or settle any such demands or approve any withdrawal of any such demands.

1.12. Certain Other Adjustments. If, between the date of this Agreement and the Effective Time, the outstanding Parent Common Stock or Company Common Stock shall have been changed into a different number of shares or different class by reason of any reclassification, recapitalization, stock split, split-up, combination or exchange of shares or a stock dividend or dividend payable in any other securities shall be declared with a record date within such period, or any similar event shall have occurred, the Merger Consideration shall be appropriately adjusted to provide to the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event.

1.13. Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made with respect to shares of Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered certificate for Company Capital Stock (a “Company Certificate”) with respect to the shares of Parent Common Stock that such holder would be entitled to receive upon surrender of such Company Certificate until such holder shall surrender such Company Certificate. Subject to the effect of applicable laws, following surrender of any such Company Certificate, there shall be paid to such holder of shares of Parent Common Stock issuable in exchange therefor, without interest, (a) promptly after the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date prior to such surrender payable with respect to such shares of Parent Common Stock and (b) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such shares of Parent Common Stock.

-6-

1.14. No Further Ownership Rights in Company Capital Stock. The Merger Consideration delivered or deliverable to the holders of Company Capital Stock in accordance with the terms of this Article I shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to the shares of Company Capital Stock. Until surrendered as contemplated by this Agreement, each Company Certificate representing Company Capital Stock shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender solely the Merger Consideration (and any cash to be paid pursuant hereto for fractional shares). In addition, until surrendered as contemplated by this Agreement, each PharmAthene Note shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender solely an 8% Convertible Note hereunder and no further interest shall accrue on the PharmAthene Notes after the Effective Time.

1.15. No Fractional Shares of Parent Common Stock.

(a) Fractional Shares. No certificates or scrip representing fractional shares of Parent Common Stock or book-entry credit of the same shall be issued upon the surrender for exchange of Company Certificates and such fractional share interests will not entitle the owner thereof to vote or to have any rights of a stockholder of Parent.

(b) Cash for Fractional Shares. Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Company Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to the product of (i) such fractional part of a share of Parent Common Stock multiplied by (ii) the closing price for a share of Parent Common Stock on The American Stock Exchange LLC (the “AMEX”) on the date of the Effective Time or, if such date is not a Business Day, the Business Day immediately before the date on which the Effective Time occurs.

1.16. No Liability. None of Parent, Merger Sub, Company or the Surviving Corporation shall be liable to any Person (as defined in Section 2.3(z)) in respect of any Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

1.17. Surrender of Certificates. Upon surrender of Company Certificates at Closing, the holders of such Company Certificates shall receive in exchange therefor Merger Consideration in accordance with Schedule 1.9(b)(i) attached hereto, as amended if applicable, and the Company Certificates surrendered shall be canceled. Until so surrendered, outstanding Company Certificates shall be deemed, from and after the Effective Time, to evidence only the right to receive the applicable Merger Consideration issuable pursuant hereto and the Allocation Agreement.

-7-

1.18. Lost, Stolen or Destroyed Certificates. If any Company Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed, Parent shall issue in exchange for such lost, stolen or destroyed certificate the Merger Consideration payable in exchange therefor; provided, however, that as a condition precedent to the issuance of such Merger Consideration, the holder of such lost, stolen or destroyed Company Certificates shall indemnify Parent against any claim that may be made against Parent or the Surviving Corporation with respect to the Company Certificates alleged to have been lost, stolen or destroyed.

1.19. Withholding Rights. Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold from the Merger Consideration payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code and the rules and Treasury Regulations promulgated thereunder, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or Parent, as the case may be, such withheld amounts shall be treated for all purposes under this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or Parent, as the case may be, and such amounts shall be delivered by the Surviving Corporation or Parent, as the case may be, to the applicable taxing authority.

1.20. Further Assurances. If at any time after the Effective Time the Surviving Corporation shall consider or be advised that any deeds, bills of sale, assignments or assurances or any other acts or things are necessary, desirable or proper (a) to vest, perfect or confirm, of record of otherwise, in the Surviving Corporation its right, title or interest in, to or under any of the rights, privileges, powers, franchises, properties or assets of either Company or Merger Sub or (b) otherwise to carry out the purposes of this Agreement, the Surviving Corporation and its proper officers and directors or their designees shall be authorized to execute and deliver, in the name and on behalf of either Company or Merger Sub, all such deeds, bills of sale, assignments and assurances and do, in the name and on behalf of Company or Merger Sub, all such other acts and things necessary, desirable or proper to vest, perfect or confirm its rights, title or interest in, to or under any of the rights, privileges, powers, franchises, properties or assets of Company or Merger Sub, as applicable, and otherwise to carry out the purposes of this Agreement.

1.21. Stock Transfer Books. The stock transfer books of Company shall be closed immediately upon the Effective Time and there shall be no further registration of transfers of shares of Company Capital Stock thereafter on the records of Company. On or after the Effective Time, any Company Certificate presented to Parent for any reason shall be converted into the Merger Consideration with respect to the shares of Company Capital Stock formerly represented thereby, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled and any dividends or other distributions to which the holders thereof are entitled.

-8-

1.22. Tax Consequences. For U.S. federal income tax purposes, the parties intend that the Merger be treated as a reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code, and that this Agreement shall be, and is hereby, adopted as a plan of reorganization for purposes of Section 368 of the Code. Accordingly, unless otherwise required by Law (as defined in Section 2.3(z)), no party shall take any action that reasonably could be expected to jeopardize the treatment of the Merger as a reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code, and the parties shall not take any position on any Tax Return (as defined herein) or in any proceeding relating to the Tax consequences of the Merger inconsistent with this Section 1.22. Notwithstanding the forgoing, the parties understand and agree that only the Stock Consideration portion of the Merger Consideration shall be deemed eligible for a “tax free” exchange under Section 368 of the Code.

1.23. Escrow. As the sole remedy for the indemnity obligations set forth in Article VIII hereof, at the Closing, an aggregate of 1,375,000 shares of Parent Common Stock issued or issuable as a result of the Merger (the “Escrow Shares”) shall be deposited into escrow to be held during the period commencing on the Closing Date and ending on the one year anniversary thereof, which shares shall be allocated among the holders of Company Capital Stock and of Company Options and Company Warrants in accordance with the terms and conditions of the Allocation Agreement and the Escrow Agreement to be entered into between Parent, Stockholders’ Representative (as defined in Article VIII) and Continental Stock Transfer & Trust Company, as escrow agent, in substantially the form of Exhibit B (the “Escrow Agreement”).

1.24. Rule 145. All shares of Parent Common Stock issued pursuant to this Agreement to “affiliates” of Company identified on Schedule 1.24 attached hereto will be subject to certain resale restrictions under Rule 145 promulgated under the Securities Act (as defined herein) and all certificates representing such shares shall bear an appropriate restrictive legend.

ARTICLE II

REPRESENTATIONS AND WARRANTIES

2.1. Representations and Warranties of Parent. Parent represents and warrants to Company, that the statements contained in this Section 2.1 are correct and complete as of the date of this Agreement and will be correct and complete as of the Closing Date (as though made then and as though the Closing Date were substituted for the date of this Agreement throughout this Section 2.1), except as set forth in the disclosure schedule to be delivered to Company by Parent on the date hereof and initialed by the parties (the “Parent Disclosure Schedule”). Disclosures made in the Parent Disclosure Schedule shall not be deemed to constitute additional representations or warranties of Parent but set forth disclosures, exceptions and exclusions called for under this Agreement provided they are set forth with reasonable particularity and describe the relevant facts in reasonable detail. The Parent Disclosure Schedule will be arranged in paragraphs corresponding to the numbered and lettered paragraphs contained in this Section 2.1.

-9-

(a) Organization, Standing and Power. Parent is a corporation duly organized, validly existing and in good standing (as defined in Article X) under the laws of the State of Delaware, has the requisite power and authority to own, lease and operate its properties and to carry on its business as now being conducted. Parent is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its activities makes such qualification or licensing necessary, except for such failures to be so duly qualified or licensed and in good standing that could not reasonably be expected to have a Material Adverse Effect (as defined in Article X). Complete and correct copies of the certificate of incorporation and bylaws of Parent, as amended and currently in effect, have been provided to Company and Parent is not in violation of any of the provisions of such organization documents. Merger Sub is a newly-formed single purpose entity which has been formed solely for the purposes of the Merger and has not carried on, and prior to the Closing will not carry on, any business or engaged in any activities other than those reasonably related to the Merger.

Following the Merger, to the Knowledge of Parent, Surviving Corporation will hold at least 90% of the fair market value of the net assets and at least 70% of the fair market value of the gross assets that were held by Company immediately prior to the Effective Time, and at least 90% of the fair market value of the net assets and at least 70% of the fair market value of the gross assets that were held by Merger Sub immediately prior to the Effective Time. Insofar as this representation is dependent upon actions of Company prior to the Merger, Parent and Merger Sub have assumed that Company will take no action prior to the Merger that will cause Company not to hold at least 90% of the fair market value of its net assets and at least 70% of the fair market value of its gross assets immediately prior to the Effective Time. For purposes of this Section 5.8, cash or other property paid by Company or Merger Sub to stockholders, or used by Company or Merger Sub to pay reorganization expenses, or distributed by Company or Merger Sub with respect to or in redemption of its outstanding stock, other than regular dividends paid in the ordinary course and other than cash or other property transferred by Parent to Merger Sub in pursuance of the plan of Merger immediately preceding, or in contemplation of, the Merger are included as assets held by Company and Merger Sub immediately prior to the Effective Time. Additionally, Parent has not participated in any plan of Company to effect (i) any distribution with respect to any Company stock (other than regular dividend distributions made in the ordinary course), or (ii) any redemption or acquisition of any Company stock (other than in the Merger).

5.9. Composition of the Board of Directors of Parent. Notwithstanding anything to the contrary contained herein, for so long as at least 30% of the principal amount of 8% Convertible Notes issued as part of the Merger Consideration remains outstanding, the number of directors constituting the Board of Directors of Parent shall be fixed at seven (7) and the holders of the 8% Convertible Notes shall have the right, as a separate class (and notwithstanding the existence of less than three (3) such holders at any given time), to elect three (3) members to the Board of Directors of Parent and, to the extent that the holders elect to fill committee positions, they shall have the right, subject to applicable Law and the regulations of the AMEX, to appoint two (2) of the three (3) members of each committee of the Board of Directors including the nominating and corporate governance committee and the compensation committee of Parent. The Parent Charter shall reflect such right of the holders of the 8% Convertible Notes. Parent and its Board of Directors shall include the names of the three (3) nominees of the holders of the 8% Convertible Notes in every proxy statement delivered to stockholders of Parent for any special or annual meeting of Parent’s stockholders at which directors are to be elected during the period commencing on the Closing Date and ending upon the date that less than 30% of the principal amount of the 8% Convertible Notes issued as Merger Consideration remains outstanding, at which time the rights of such holders under this Section 5.9 shall terminate.

7.2. Effect of Termination.

(a) In the event of the termination of this Agreement pursuant to Section 7.1, the obligations of the parties under this Agreement shall terminate and there shall be no liability on the part of any party hereto, except for the obligations in the confidentiality provisions hereof, and all of the provisions of this Section 7.2, Section 7.3, Section 7.4 and Section 9.11; provided, however, that no party hereto shall be relieved or released from any liabilities or damages arising out of its willful breach of any provision of this Agreement.

(b) In the event that this Agreement is terminated by Parent pursuant to Section 7.1(d)(i) and 7.1(d)(ii)(and, in the case of the failure to fulfill conditions, such failure is within Company’s control which shall be deemed to include a failure of the Company, its stockholders or holders of PharmAthene Notes to agree upon the terms of any re-allocation of the Merger Consideration which may be made necessary as a result of a Company Subsequent Issuance or an issuance in connection with any financing transaction with General Electric Capital Corp.), then Company shall be obligated to pay to Parent, within five (5) business days of such termination, the sum of $250,000 (the “Termination Fee”) in cash.

ARTICLE VIII

REMEDIES FOR BREACH OF AGREEMENT

8.1. Survival of Representations and Warranties. All of the representations and warranties of the parties contained in this Agreement shall survive the Closing hereunder (unless the non-breaching party had received from the breaching party written notice of any misrepresentation or breach of warranty prior to the time of Closing and expressly waived in writing such breach or misrepresentation) and continue in full force and effect until a period of twelve (12) months from the Closing Date (“Survival Period”).

8.2. Indemnification Provisions for Benefit of Parent. In the event that Company violates, misrepresents or breaches (or in the event any third party alleges facts that are ultimately proven or conceded to represent a Company violation, misrepresentation or breach) any of its representations, warranties, and covenants contained herein including, without limitation, the covenants and agreements of Company and PA Management Team to provide Company Information contained in Section 4.1(b) hereof and, if there is an applicable Survival Period pursuant to Section 8.1 above, provided that the Parent Representative makes a written claim for indemnification against Company pursuant to Section 8.6 below within the Survival Period, then the Indemnifying Stockholders (as defined in Article X) agree to indemnify Parent from and against the entirety of any Adverse Consequences (as defined in Article X) that Parent may suffer through and after the date of the claim for indemnification (including any Adverse Consequences Parent may suffer after the end of any applicable Survival Period) resulting from, arising out of, relating to, in the nature of, or caused by the violation, misrepresentation or breach. Any liability incurred by the Indemnifying Stockholders pursuant to the terms of this Article VIII shall be limited to, and paid by, the Indemnifying Stockholders to Parent by return for cancellation of the Escrow Shares in accordance with Section 8.6 hereof which shall represent the sole and exclusive source for payment of any indemnification obligations of the Indemnifying Stockholders. All determinations relating to the submission of claims for the benefit of Parent hereunder shall be determined, in good faith, solely by the nominees of Parent to the Board of Directors. Notwithstanding Company’s disclosure in Item 2 of Section 2.3(h)(i) of the Company Disclosure Schedule (the “Section 2.3(h) disclosure”), Parent shall have the right to indemnification under this Article VIII, subject to all of the terms and conditions of this Article VIII (including, without limitation, meeting the indemnification threshold set forth in Section 8.7 and the limitations set forth in Section 8.5), with respect to any Adverse Consequences suffered by Parent as a result of any claims relating to such Section 2.3(h) disclosure which claims are not resolved prior to Closing. For the avoidance of doubt, the parties expressly acknowledge and agree that the resolution of any claims relating to the Section 2.3(h) disclosure occurring prior to Closing shall be within the sole discretion of Company and shall in no way effect the Merger Consideration or be applicable towards the indemnification threshold or otherwise be subject to indemnification.

8.3. Matters Involving Third Parties.

(a) If any third party shall notify any party (the “Indemnified Party”) with respect to any matter (a “Third Party Claim”) which may give rise to a claim for indemnification against any other party (the “Indemnifying Party”) under this Article VIII, then the Indemnified Party shall promptly (and in any event within ten (10) business days after receiving notice of the Third Party Claim) notify each Indemnifying Party and the Escrow Agent thereof in writing (an “Indemnification Notice”); provided, however, that no delay on the part of the Indemnified Party in notifying any Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party thereby is prejudiced.

-69-

(b) Any Indemnifying Party will have the right to defend the Indemnified Party against the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party so long as (i) the Indemnifying Party notifies the Indemnified Party in writing within thirty (30) business days (or earlier in the event the underlying Third Party claim requires action) after the Indemnified Party has given notice of the Third Party Claim that the Indemnifying Party will indemnify the Indemnified Party from and against the entirety of any Adverse Consequences the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim, (ii) the Indemnifying Party provides the Indemnified Party with evidence reasonably acceptable to the Indemnified Party that the Indemnifying Party will have the financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder, (iii) the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief, (iv) settlement of, or an adverse judgment with respect to, the Third Party Claim is not, in the good faith judgment of the Indemnified Party, likely to establish a precedent or practice materially adverse to the continuing business interests of the Indemnified Party, and (v) the Indemnifying Party conducts the defense of the Third Party Claim actively and diligently.

(c) So long as the Indemnifying Party is conducting the defense of the Third Party Claim in accordance with Section 8.3(b) above, (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (ii) the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (not to be withheld unreasonably) and (iii) the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be withheld unreasonably).

(d) In the event that any of the conditions in Section 8.3(b) above fail to be complied with, however, (i) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Third Party Claim in any manner it reasonably may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, any Indemnifying Party in connection therewith), (ii) the Indemnifying Parties will reimburse the Indemnified Party promptly and periodically for the costs of defending against the Third Party Claim (including reasonable attorneys’ fees and expenses), and (iii) the Indemnifying Parties will remain responsible for any Adverse Consequences the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim to the fullest extent provided in this Article VIII.

-70-

(e) Notwithstanding anything to the contrary contained in this Article VIII, Parent, Company and Merger Sub shall not settle and pay any Third Party Claim unless and until Parent shall have obtained the prior written consent of the Stockholders’ Representative to such settlement which consent the Stockholders’ Representative shall not unreasonably withhold or delay.

8.4. Determination of Adverse Consequences. All claims for indemnification payments under this Article VIII shall be made in good faith and although a claim may be made hereunder, no payments shall be made for the benefit of the Indemnified Party until the Indemnified Party has incurred actual out-of pocket expenses. In the event that Parent has made a claim for indemnification prior to the termination of any applicable Survival Period, no Escrow Shares held in escrow pursuant to this Article VIII and the Escrow Agreement shall be released from the escrow until such time as the claim has been resolved unless the Survival Period shall have expired after the making of such claim but before such claim is fully resolved, in which case the Escrow Shares in excess of the Fair Market Value of the amount of Adverse Consequence shall be released from Escrow.

8.5. Escrow of Shares by Indemnifying Stockholders. As the sole and exclusive source for the payment of the indemnification obligations of the Indemnifying Stockholders under this Article VIII, Company and the Indemnifying Stockholders hereby authorize Parent to withhold, from the delivery of the Stock Consideration otherwise deliverable to the Indemnifying Stockholders as part of the Merger Consideration, for delivery into escrow, pursuant to the Escrow Agreement, 1,375,000 shares of Parent Common Stock which shall be allocated among the Indemnifying Stockholders in accordance with the relative proportions established by the Allocation Agreement as provided to Parent in a certificate executed and delivered by Company at Closing (the “Company Closing Certificate”).

(a) Escrow Shares. The Escrow Shares shall be withheld from delivery to the Indemnifying Stockholders and segregated from shares issuable upon the exercise of Company Options and Company Warrants at Closing and placed in escrow pursuant to the terms of the Escrow Agreement. The Escrow Shares shall be registered in the name of each Indemnifying Stockholder in the amounts set forth on the Company Closing Certificate, and shall be held by Continental Stock Transfer & Trust Company (the “Escrow Agent”), and shall constitute the escrow fund (the “Escrow Fund”) governed by the terms of the Escrow Agreement. In the event that Parent issues any additional shares of Parent Common Stock to the Indemnifying Stockholders for any reason, such additional shares shall be issued in the name of such Indemnifying Stockholders as applicable and shall not be subject to escrow. Once released from the Escrow Fund, shares of Parent Common Stock shall cease to be Escrow Shares.

(b) Payment of Dividends; Voting. Any cash dividends, dividends payable in securities, or other distributions of any kind made in respect of the Escrow Shares will be delivered promptly to the Indemnifying Stockholders. The Indemnifying Stockholders (other than the holders of Company Options and Company Warrants) shall be entitled to vote the Escrow Shares on any matters to come before the stockholders of Parent, with each Indemnifying Stockholder being entitled to direct the voting of its or his Escrow Shares listed on the Company Closing Certificate.

-71-

(c) Distribution of Escrow Shares. At the times provided for in Section 8.5(e), the Escrow Shares shall be released to the Indemnifying Stockholders (and to Parent on behalf of holders of Company Options and Company Warrants) in accordance with the Company Closing Certificate unless the Stockholders’ Representative shall have instructed the Escrow Agent otherwise in writing, in which case the Escrow Agent and the Parent shall be entitled to rely upon such instructions. Parent will take such action as may be necessary to cause such certificates to be issued in the names of the appropriate persons. Certificates representing Escrow Shares so issued that are subject to resale restrictions under applicable securities laws will bear a legend to that effect. No fractional shares shall be released and delivered from the Escrow Fund to the Indemnifying Stockholders and all fractional shares shall be rounded to the nearest whole share.

(d) Assignability. No Escrow Shares or any beneficial interest therein may be pledged, sold, assigned or transferred, including by operation of law, by any Indemnifying Stockholders or be taken or reached by any legal or equitable process in satisfaction of any debt or other liability of any such stockholder, prior to the delivery to such Indemnifying Stockholders of its or his pro rata portion of the Escrow Fund by the Escrow Agent as provided herein.

(e) Release from Escrow Fund. Within five (5) business days following expiration of the Survival Period (the “Release Date”), the Escrow Shares will be released from the Escrow Fund to the Indemnifying Stockholders less the number of Escrow Shares, if any, with a Fair Market Value equal to the amount of Adverse Consequences set forth in any Indemnification Notice from Parent with respect to any pending but unresolved claim for indemnification. Prior to the Release Date, the Parent Representative and the Stockholder Representative shall issue to the Escrow Agent a certificate executed by each of them instructing the Escrow Agent to release such number of Escrow Shares determined in accordance with this Section 8.5(e). Any Escrow Shares retained in the Escrow Fund as a result of the immediately preceding sentence shall be released to the Indemnifying Stockholders or Parent, as appropriate, promptly upon resolution of the related claim for indemnification in accordance with the provisions of this Article VIII. For purposes of this Article VIII, the “Fair Market Value” shall be the average reported last sales price for the ten (10) trading days ending on the last day prior to the date that the claim for indemnification is publicly disclosed (or if there is no public disclosure, the date on which the Indemnification Notice is received) and the ten (10) trading days after such date; provided, however, the Stockholders’ Representative and the Parent Representative acting together shall have the right to assign a different value to the Escrow Shares in order to settle or pay any Third Party Claim in the event the third party claimant is willing to accept the Escrow Shares in full or partial settlement therefor.

(i) MPM BioVentures III-QP, L.P. is hereby constituted and appointed jointly as the Stockholders’ Representative for and on behalf of the Indemnifying Stockholders to give and receive notices and communications, to authorize delivery to Parent of shares of Parent Common Stock from the Escrow Fund in satisfaction of indemnification claims by Parent, to object to such deliveries, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to such claims (including Third Party Claims), and to take all actions necessary or appropriate in the judgment of the Stockholders’ Representative for the accomplishment of the foregoing. Such agency may be changed by from time to time upon not less than ten (10) days’ prior written notice, executed by the Stockholders’ Representative, to the Parent Representative. No bond shall be required of the Stockholders’ Representative, and the Stockholders’ Representative shall receive no compensation for his services. Notices or communications to or from the Stockholders’ Representative shall constitute notice to or from Company and each of the Indemnifying Stockholders.

-72-

(ii) The Stockholders’ Representative shall not be liable for any act done or omitted hereunder as Stockholders’ Representative while acting in good faith and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith.

(iii) A decision, act, consent or instruction of the Stockholders’ Representative shall constitute a decision of all Indemnifying Stockholders for whom Escrow Shares otherwise issuable to them are deposited in escrow and shall be final, binding, and conclusive upon each such Indemnifying Stockholder, and Parent may rely upon any decision, act, consent, or instruction of the Stockholders’ Representative as being the decision, act, consent or instruction of each and every such Indemnifying Stockholder. The Stockholders’ Representative shall have the right to consent to the use of the Escrow Shares to settle any claims made hereunder. For purposes of clarification, in connection with the settlement or payment of any claims for indemnification hereunder, the “Fair Market Value” of the Escrow Shares as defined under this Article VIII, shall not be binding upon the Parent or Stockholders’ Representative if they mutually agree upon any value other than Fair Market Value and shall also have the discretion to mutually agree to use the Escrow Shares to settle or pay any Third Party Claims.

(iv) ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ is hereby constituted and appointed jointly as the Parent Representative for and on behalf of the Parent to give and receive notices and communications, to negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to such claims (including Third Party Claims), and to take all actions necessary or appropriate in the judgment of the Parent Representative for the accomplishment of the foregoing. Such agency may be changed by from time to time upon not less than ten (10) days’ prior written notice, executed by the Parent Representative, to the Stockholders’ Representative. No bond shall be required of the Parent Representative, and the Parent Representative shall receive no compensation for his services. Notices or communications to or from the Parent Representative shall constitute notice to or from Parent.

-73-

(v) The Parent Representative shall not be liable for any act done or omitted hereunder while acting in good faith and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Parent shall indemnify the Parent Representative and hold him harmless against any loss, liability, or expense incurred without gross negligence or bad faith on the part of the Parent Representative and arising out of or in connection with the acceptance or administration of his duties hereunder.

(vi) A decision, act, consent or instruction of the Parent Representative shall constitute a decision of Parent under this Article VIII and shall be final, binding, and conclusive upon Parent. The Stockholders’ Representative and the Indemnifying Stockholders may rely upon any decision, act, consent, or instruction of the Parent Representative as being the decision, act, consent or instruction of the Parent. The Parent Representative shall have the right to consent to the use of the Escrow Shares to settle any claim for which Parent is entitled to indemnification under this Article VIII. For purposes of clarification, in connection with the settlement or payment of any claims for indemnification hereunder, the “Fair Market Value” of the Escrow Shares as defined under this Article VIII, shall not be binding upon the Parent Representative or Stockholders’ Representative if they mutually agree upon any value other than Fair Market Value and shall also have the discretion to mutually agree to use the Escrow Shares to settle or pay any Third Party Claims.

8.6. Determination/Resolution of Claims.

(a) If an Indemnified Party wishes to make a claim for indemnification against an Indemnifying Party, such Indemnified Party shall deliver the Indemnification Notice to the Indemnifying Party and to the Escrow Agent on or before the expiration of the Survival Period. Such Indemnification Notice shall contain the amount of Adverse Consequences for which the Indemnified Party is seeking indemnification and shall set forth the reasons therefore in reasonable detail.

(b) If Parent asserts a claim upon the Escrow Fund by delivering an Indemnification Notice to the Stockholders’ Representative and the Escrow Agent on or before the end of the Survival Period, the Escrow Agent shall retain in the Escrow Fund such number of shares of Parent Common Stock as shall be determined in accordance with Section 8.5(e) above.

-74-

(c) Unless the Stockholders’ Representative shall notify Parent in writing within thirty (30) days after receipt of an Indemnification Notice that the Stockholders’ Representative objects to any claim for indemnification set forth therein, which notice shall include a reasonable explanation of the basis for such objection, then such indemnification claim shall be deemed to be accepted by the Stockholders’ Representative and the parties shall issue to the Escrow Agent a certificate executed by the Parent Representative and the Stockholders’ Representative indicating what number of Escrow Shares are to be released to Parent. If the Stockholders’ Representative shall timely notify Parent in writing that it objects to any claim for indemnification made in such an Indemnification Notice, Parent shall have fifteen (15) days from receipt of such notice to respond in a written statement to such objection. If after thirty (30) days following receipt of Parent’s written statement, there remains a dispute as to any indemnification claims set forth in the Indemnification Notice, the Stockholders’ Representative and the Parent Representative shall attempt in good faith for sixty (60) days to agree upon the rights of the respective parties with respect to each of such claims. If the Stockholders’ Representative and the Parent Representative should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties. Based upon the memorandum, the parties shall issue to the Escrow Agent a certificate executed by the Parent Representative and the Stockholders’ Representative indicating what number of Escrow Shares are to be released to Parent. The Escrow Agent shall be entitled to rely on any such certificate and disburse Escrow Shares from the Escrow Fund in accordance with the terms thereof.

(d) If the Stockholders’ Representative and the Parent Representative cannot resolve a dispute during the sixty-day period (or such longer period as the parties may agree to in writing), then such dispute shall be submitted (and either party may submit such dispute) for arbitration before a single arbitrator in Wilmington, Delaware, in accordance with the commercial arbitration rules of the American Arbitration Association then in effect. The Stockholders’ Representative and the Parent Representative shall attempt to agree upon an arbitrator. In the event that the Stockholders’ Representative and the Parent Representative are unable to agree upon an arbitrator within ten (10) days after the date on which the disputed matter may, under this Agreement, be submitted to arbitration, then either the Stockholders’ Representative or the Parent Representative, upon written notice to the other, may apply for appointment of such arbitrator by the American Arbitration Association. Each party shall pay the fees and expenses of counsel used by it and 50% of the fees and expenses of the arbitrator and of the other expenses associated with the arbitration. The arbitrator shall render his decision within ninety (90) days after his appointment, such decision shall be in writing and shall be final and conclusive on the parties. The decision shall be submitted to the Escrow Agent which shall act in accordance therewith.

8.7. Indemnification Threshold. Notwithstanding anything to the contrary contained herein, no Person or Party shall have any obligation to indemnify Parent or Company, as the case may be, from and against any Adverse Consequences caused proximately by the breach of any representation or warranty of Parent or Company hereunder, as the case may be, until Parent or Company, as the case may be, has suffered Adverse Consequences by reason of all such breaches (or alleged breaches) in excess of $500,000 in the aggregate, with no single Adverse Consequence being valued at less than $50,000.

-75-

8.8. Other Indemnification Provisions.

(a) Any Indemnified Party seeking indemnification under this Article VIII shall be required to take all reasonable actions to mitigate the damages associated with the Adverse Consequences.

(b) Notwithstanding any provision contained in this Agreement, no indemnification claim shall be maintained by any party for breach of representations or warranties of the other party if such claiming party had knowledge of the breach of the representations and warranties on or before the Closing.

(c) No recovery for indemnification shall include recovery for special, incidental, punitive or consequential damages. All claims for indemnification shall be subject to reduction or offset for any tax benefits associated with or insurance proceeds applicable to the claim.
