THIS VOTING AGREEMENT (“Agreement”), dated as of December 18, 2009, is made by and among Myriad Pharmaceuticals, Inc., a Delaware corporation (“Parent”), Javelin Pharmaceuticals, Inc., a Delaware corporation (the “Company”), and the undersigned holder (“Stockholder”) of shares of capital stock of Parent (the “Shares”).

WHEREAS, Parent, MPI Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and the Company have entered into an Agreement and Plan of Merger, dated of even date herewith (as such agreement may be subsequently amended or modified, the “Merger Agreement”), providing for the merger of Merger Sub with and into the Company (the “Merger”);

WHEREAS, Stockholder beneficially owns and has sole voting power (or shares such power with Stockholder’s spouse) with respect to the number of Shares, and holds stock options or other rights to acquire the number of Shares indicated opposite Stockholder’s name on Schedule 1 attached hereto;

WHEREAS, as an inducement to, and a condition to the willingness of, the Company to enter into the Merger Agreement, and in consideration of the substantial expenses incurred and to be incurred by it in connection therewith, Stockholder has agreed to enter into and perform this Agreement; and

WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Merger Agreement.

NOW, THEREFORE, in consideration of, and as a condition to, the Company entering into the Merger Agreement and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by it in connection therewith, Stockholder, Parent, and the Company agree as follows:

1. Agreement to Vote Shares. Stockholder agrees that, prior to the Expiration Date (as defined in Section 2 below), at any meeting of the stockholders of Parent or any adjournment or postponement thereof, or in connection with any written consent of the stockholders of Parent, with respect to the Merger or the Merger Agreement, Stockholder shall:

(a) appear at such meeting or otherwise cause the Shares and any New Shares (as defined in Section 3 below) to be counted as present thereat for purposes of calculating a quorum;

(b) from and after the date hereof until the Expiration Date, vote (or cause to be voted), or deliver a written consent (or cause a written consent to be delivered) covering all of the Shares and any New Shares that such Stockholder shall be entitled to so vote, in favor of the issuance of shares of Parent Common Stock pursuant to the Merger Agreement and all other transactions contemplated by the Merger Agreement and any matter necessary for consummation of the Merger as to which stockholders of Parent are called upon to vote in favor of or consent to. The Stockholder shall not take or commit or agree to take any action inconsistent with the foregoing.

2. Expiration Date. As used in this Agreement, the term “Expiration Date” shall mean the earlier to occur of (a) the Merger Effective Time, (b) such date and time as the Merger Agreement shall be terminated pursuant to Article X thereof or otherwise, or (c) upon mutual written agreement of each of the parties to terminate this Agreement. This Agreement shall automatically terminate upon the Expiration Date. Upon termination or expiration of this Agreement, no party shall have any further obligations or liabilities under this Agreement; provided, however, such termination or expiration shall not relieve any party from liability for any willful breach of this Agreement or acts of bad faith prior to termination hereof.

3. Additional Purchases. Stockholder agrees that any shares of capital stock or other equity securities of Parent that Stockholder purchases or with respect to which Stockholder otherwise acquires sole voting power (or shared voting power with Stockholder’s spouse) after the execution of this Agreement and prior to the record date for determining the Parent stockholders entitled to vote with respect to the Merger, whether by the exercise of any stock options or otherwise (“New Shares”), shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted the Shares.

4. Agreement to Retain Shares. From and after the date hereof until the Expiration Date, Stockholder shall not, directly or indirectly, knowingly take any action that would make any representation or warranty of Stockholder contained herein untrue or incorrect in any material respect or have the effect of preventing or disabling Stockholder from performing Stockholder’s obligations under this Agreement. Notwithstanding the foregoing, Stockholder may make transfers of Shares (a) by will or by operation of law or other transfers for estate-planning purposes, in which case this Agreement shall bind all transferees and (b) as the Company may otherwise agree in writing in its sole discretion. Notwithstanding anything contained herein to the contrary, nothing in this Agreement shall prohibit or prevent the cashless exercise of any Parent Stock Options by Stockholder.

5. Representations and Warranties of Stockholder. Stockholder hereby represents and warrants to Parent and the Company as follows:
