THERACLONE VOTING AND LOCK-UP AGREEMENT

This THERACLONE VOTING AND LOCK-UP AGREEMENT (this “Agreement”), dated as of July 31, 2013, is by and between, PharmAthene, Inc., a Delaware corporation (the “Company”), and each of the undersigned stockholders (each, a “Stockholder,” and, collectively, the “Stockholders”) of Theraclone Sciences, Inc., a Delaware corporation (“Theraclone”), identified on the signature page hereto.

A.           The Company, Theraclone and Taurus Merger Sub, Inc., a Delaware corporation and direct, wholly owned subsidiary of the Company (“Merger Sub”) and Steven Gillis, Ph.D., solely in its capacity as the representative of the Theraclone Stockholders, are entering into an Agreement and Plan of Merger (as amended from time to time, the “Merger Agreement”), dated as of the date hereof, pursuant to which Merger Sub will merge with and into Theraclone (the “Merger”), after which time Theraclone will be a direct, wholly owned subsidiary of the Company;

B.           As of the date hereof, each Stockholder is the Beneficial Owner (as defined below) of, and has the sole (subject to applicable community property laws) right to vote and dispose of, that number of each class of the issued and outstanding capital stock (the “Theraclone Shares”) of Theraclone set forth opposite such Stockholder’s name on Schedule A hereto; and

C.           Concurrently with the entry by the Company, Theraclone and Merger Sub into the Merger Agreement, and as a condition and inducement to the willingness of the Company to enter into the Merger Agreement and incur the obligations set forth therein, the Company has required that the Stockholders enter into this Agreement.

Accordingly, and in consideration of the foregoing and the mutual representations, warranties, covenants and agreements contained herein, the parties hereto, intending to be legally bound, hereby agree as follows:

ARTICLE I.
Definitions

Capitalized terms used but not defined in this Agreement are used in this Agreement with the meanings given to such terms in the Merger Agreement. In addition, for purposes of this Agreement:

“Affiliate” means, with respect to any specified person, a person who, at the time of determination, directly or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such specified person. For purposes of this Agreement, with respect to a Stockholder, “Affiliate” does not include Theraclone and the persons that directly, or indirectly through one or more intermediaries, are controlled by Theraclone. For the avoidance of doubt, no officer or director of Theraclone will be deemed an Affiliate of another officer or director of Theraclone by virtue of his or her status as an officer or director of Theraclone.

“Beneficially Owned” or “Beneficial Ownership” with respect to any securities means having beneficial ownership of such securities (as determined pursuant to Rule 13d-3 under the Exchange Act, disregarding the phrase “within 60 days” in paragraph (d)(1)(i) thereof), including pursuant to any agreement, arrangement or understanding, whether or not in writing. Without duplicative counting of the same securities, securities Beneficially Owned by a person include securities Beneficially Owned by (i) all Affiliates of such person, and (ii) all other persons with whom such person would constitute a “group” within the meaning of Section 13(d) of the Exchange Act and the rules promulgated thereunder.

“Beneficial Owner” with respect to any securities means a person that has Beneficial Ownership of such securities.

“person” has the meaning ascribed thereto in the Merger Agreement.

“Subject Shares” means, with respect to a Stockholder, without duplication, (i) the Theraclone Shares owned by such Stockholder on the date hereof as described on Schedule A, (ii) any additional shares of Theraclone acquired by such Stockholder, over which such Stockholder acquires Beneficial Ownership from and after the date hereof, whether pursuant to existing stock option agreements, warrants or otherwise, and (iii) any shares into which the Theraclone Shares may be converted, exchanges or reclassified. Without limiting the other provisions of this Agreement, in the event that Theraclone changes the number of Theraclone Shares issued and outstanding prior to the Expiration Date (as defined below) as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, combination, recapitalization, subdivision, or other similar transaction, the number of Subject Shares subject to this Agreement will be equitably adjusted to reflect such change.

“Transfer” means, with respect to a security, the sale, transfer, pledge, hypothecation, encumbrance, assignment or disposition of such security or the Beneficial Ownership thereof, and each option, agreement, arrangement or understanding, whether or not in writing, to effect any of the foregoing. As a verb, “Transfer” has a correlative meaning.

ARTICLE II.
Covenants of Stockholders

2.1         Irrevocable Proxy. Concurrently with the execution of this Agreement, each Stockholder agrees to deliver to the Company a proxy in the form attached hereto as Exhibit A (the “Proxy”), which will be irrevocable to the extent provided in Section 212 of the Delaware General Corporation Law, with respect to the Subject Shares referred to therein.

2.2         Agreement to Vote.

(a)          At each and every meeting of the stockholders of Theraclone held prior to the Expiration Date, however called, and at every adjournment or postponement thereof prior to the Expiration Date, or in connection with each and every written consent of, or any other action by, the stockholders of Theraclone given or solicited prior to the Expiration Date, each Stockholder will vote, or provide a consent with respect to, all of the Subject Shares entitled to vote or to consent thereon (i) in favor of the adoption of the Merger Agreement and any actions required in furtherance thereof, (ii) in favor of the approval of the conversion of all outstanding shares of Theraclone Preferred Stock into Theraclone Common Shares on a 1:1 basis (as of immediately prior to the Effective Time and contingent upon the Merger occurring) pursuant to Theraclone’ Restated Certificate of Incorporation, (iii) against any other proposal or transaction involving Theraclone, the effect of which amendment or other proposal or transaction is to delay, impair, prevent or nullify the Merger or the transactions contemplated by the Merger Agreement, (iv) against any amendment of Theraclone’s certificate of incorporation or bylaws that changes in any manner the voting rights of any capital stock of Theraclone (other than the conversion of Theraclone Preferred Stock into Theraclone Common Shares), and (v) against any other action or agreement that would result in a breach in any material respect of any covenant, representation or warranty of the Merger Agreement.

(b)          No Stockholder will enter into any agreement with any person (other than the Company) prior to the Expiration Date (with respect to periods prior to or after the Expiration Date) directly or indirectly to vote, grant any proxy or give instructions with respect to the voting of, the Subject Shares in respect of the matters described in Section 2.2 hereof, or the effect of which would be inconsistent with or violate any provision contained in this Section 2.2.

(b)          Unless required by applicable Law or permitted by the Merger Agreement, such Stockholder will not, and will not authorize or direct any of its Affiliates or Representatives to, make any press release or public announcement with respect to this Agreement or the Merger Agreement or the transactions contemplated hereby or thereby, without the prior written consent of the Company in each instance.

No Stockholder may assign any of its rights or delegate any of its obligations under this Agreement without the prior written consent of the Company, except a Transfer by a Stockholder to a Permitted Transferee in accordance with Section 2.4.

Nothing expressed or referred to in this Agreement will be construed to give any person, other than the parties to this Agreement, any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement except such rights as may inure to a successor or permitted assignee under this Section.

8.8           Enforcement of Agreement. Each Stockholder acknowledges and agrees that the Company could be damaged irreparably if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by any Stockholder could not be adequately compensated by monetary damages. Accordingly, each Stockholder agrees that, (a) it will waive, in any action for specific performance, the defense of adequacy of a remedy at law, and (b) in addition to any other right or remedy to which the Company may be entitled, at law or in equity, the Company will be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.

8.9           Waiver. The rights and remedies of the parties to this Agreement are cumulative and not alternative. Neither any failure nor any delay by a party in exercising any right, power or privilege under this Agreement, the Proxy or any of the documents referred to in this Agreement will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. To the maximum extent permitted by applicable Law, (a) no claim or right arising out of this Agreement, the Proxy or any of the documents referred to in this Agreement can be discharged by one party, in whole or in part, by a waiver or renunciation of the claim or right unless in a written document signed by the other party, (b) no waiver that may be given by a party will be applicable except in the specific instance for which it is given, and (c) no notice to or demand on one party will be deemed to be a waiver of any obligation of that party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement, the Proxy or the documents referred to in this Agreement.

8.10         Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto will be governed by, construed under and enforced in accordance with the laws of the State of Delaware, without giving effect to principles of conflict or choice of laws.

8.11         Consent to Jurisdiction.

Process in any suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any of the named courts. Without limiting the foregoing, each party agrees that service of process on it by notice as provided in Section 8.2 will be deemed effective service of process.
