WHEREAS, as of the date hereof, the Stockholder is the Beneficial Owner or record owner of 2,649,000 shares of common stock, par value $0.001 per share (“Aegerion Common Stock”), of Aegerion;

WHEREAS, the Merger Agreement is required under Section 251 of the Delaware General Corporation Law (the “DGCL”) to be adopted by the affirmative vote of the holders of a majority of the outstanding Shares (as defined below) entitled to vote on such matter; and

WHEREAS, as a condition to the willingness of QLT and MergerCo to enter into the Merger Agreement, and in order to induce QLT and MergerCo to enter into the Merger Agreement, the Stockholder has agreed to enter into this Voting Agreement.

NOW, THEREFORE, in consideration of the premises and of the mutual agreements and covenants set forth herein and in the Merger Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto agree as follows:

DEFINITIONS

1.1 Capitalized Terms. Capitalized terms used but not defined in this Voting Agreement shall have the meanings ascribed to them in the Merger Agreement.

Without duplicative counting of the same securities by the same holder, securities Beneficially Owned by a Person shall

include securities Beneficially Owned by all other Persons who are Affiliates of such Person and who together with such Person would constitute a “group” within the meaning of Section 13(d)(3) of the Exchange Act, but excluding any Owned Shares that may be owned by employees of the Stockholder or its Affiliates in their capacity as directors of Aegerion.

(b) “Owned Shares” means, collectively, all (i) Shares and other voting securities of Aegerion held of record or Beneficially Owned by the Stockholder as of the date hereof and (ii) Shares and other voting securities of Aegerion that become owned (whether Beneficially Owned or of record) by the Stockholder, whether upon the exercise of Adjusted Options or Adjusted RSUs, conversion of convertible securities or otherwise, after the execution of this Voting Agreement.

(c) “QLT Common Shares” means, the common shares without par value of QLT to be received by the Stockholder as Merger Consideration pursuant to the Merger Agreement.

(d) “Shares” means shares of Aegerion Common Stock.

ARTICLE II

TRANSFER AND VOTING OF SHARES

2.1 No Transfer of Shares. The Stockholder shall not, directly or indirectly, (a) sell, pledge, encumber, assign, transfer or otherwise dispose of any or all of the Owned Shares or any interest in the Owned Shares, (b) deposit the Owned Shares or any interest in the Owned Shares into a voting trust or enter into a voting agreement or arrangement with respect to any of his, her or its Shares or grant any proxy or power of attorney with respect thereto or (c) enter into any contract, commitment, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, assignment, pledge, encumbrance, transfer or other disposition (whether by actual disposition or effective economic disposition due to hedging, cash settlement or otherwise) of any of the Owned Shares (any such action in clause (a), (b) or (c) above, a “transfer”). Notwithstanding anything to the contrary in the foregoing sentence, this Section 2.1 shall not prohibit a transfer of Owned Shares by the Stockholder if (a) the Stockholder is an individual, (i) to any member of the Stockholder’s immediate family or to a trust for the benefit of the Stockholder or any member of the Stockholder’s immediate family, or (ii) upon the death of the Stockholder to such Stockholder’s heirs, or (b) the Stockholder is a partnership or limited liability company, to one or more partners or members of the Stockholder or to an Affiliate under common control with the Stockholder, as applicable; provided, however, that in each case a transfer shall be permitted only if as a condition precedent to the effectiveness of such transfer, the transferee agrees in a writing, satisfactory in form and substance to QLT, to be bound by all of the terms of this Voting Agreement.

2.2 Vote in Favor of the Merger and Related Matters. The Stockholder, solely in the Stockholder’s capacity as a stockholder of Aegerion (and not, if applicable, in the Stockholder’s capacity as an officer or director of Aegerion), agrees that, from and after the date hereof until the Expiration Date (as defined below), at any meeting of the stockholders of Aegerion or any adjournment thereof, or in connection with any action by written consent of the stockholders of Aegerion, the Stockholder shall:

(a) appear at each such meeting or otherwise cause all of the Owned Shares to be counted as present thereat for purposes of calculating a quorum;

(b) vote (or cause to be voted), in person or by proxy, or deliver a written consent (or cause a consent to be delivered) covering, all of the Owned Shares: (i) in favor of the adoption of the Merger Agreement and approval of the Merger and the other transactions contemplated by the Merger Agreement, including, but not limited to, any stockholder vote required by the Aegerion Organizational Documents or Section 251 of the DGCL, and (ii) except for the Merger and the Merger Agreement, against any Aegerion Acquisition Proposal.

During the term of this Voting Agreement, the Stockholder shall retain, at all times, the right to vote its Owned Shares in its sole discretion and without any other limitation on those matters other than those set forth in this Section 2.2 that are at any time or from time to time presented for consideration to Aegerion’s stockholders, generally.

2.3 Termination. This Voting Agreement and the obligations of the Stockholder pursuant to this Voting Agreement shall terminate upon the earlier to occur of (a) the date the Merger Agreement shall have been validly terminated pursuant to its terms, (b) the date of (i) any amendment, modification, change or waiver to any provision of the Merger Agreement that reduces the amount or changes the form of the Merger Consideration, (ii) any amendment, modification, change or waiver to any provision any of Section 5.12 of the Merger Agreement or (iii) any other material amendment, modification, change or waiver to any provision of the Merger Agreement, (c) in the event of an Aegerion Change of Recommendation or a QLT Change of Recommendation, in any such case in accordance with the terms of the Merger Agreement, and (d) the Effective Time (such earlier date, the “Expiration Date”).

2.4 Stockholder Capacity. The parties acknowledge that this Voting Agreement is entered into by the Stockholder in his, her or its capacity as owner of the Owned Shares and that nothing in this Voting Agreement shall in any way restrict, limit or prohibit the Stockholder or any Affiliate or representative of the Stockholder from exercising his or her fiduciary duties in his or her capacity as a director or officer of Aegerion.

GENERAL PROVISIONS

6.1 Entire Agreement; Amendments. This Voting Agreement, the Merger Agreement and the other agreements referred to therein constitute the entire agreement of the parties hereto and supersede all prior agreements and undertakings, both written and oral, between the parties hereto with respect to the subject matter hereof.

6.7 No Waiver. No failure or delay by any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. None of the parties hereto shall be deemed to have waived any claim available to such party arising out of this Voting Agreement, or any right, power or privilege hereunder, unless the waiver is expressly set forth in writing duly executed and delivered on behalf of such waiving party.
