 WITNESSETH: 
 The Company desires to employ the Executive, and the Executive wishes to accept such employment with the
Company, upon the terms and conditions set forth in this Agreement. 
 In consideration of the mutual promises and agreements set forth

Executive hereby accepts such employment by the Company upon the terms and conditions hereinafter set forth. 
 2. Employment Period.
Subject to the provisions of Section hereof, the term of this Agreement shall be for an initial period of five (5) years from the Effective Date, and may be renewed for an additional period to be mutually determined by the parties hereto on the
same terms and conditions as set forth herein. The term of the Executive’s employment hereunder, including any continuation of the original term, is hereinafter referred to as the “Employment Period.”

but not limited to incentive stock options, pursuant to the Company’s stock incentive plan, in recognition of the Executive’s performance for the preceding year. Nothing herein should be interpreted as a guarantee of a salary increase,
merit bonus, or 








 
grant of stock incentives. The Company shall use commercially reasonable efforts to pay any cash bonuses that the Executive receives by April lst of the
following year. 
 4. Duties. The Executive shall be employed as an executive of the Company, and shall have such executive level
duties as are assigned or delegated to him by the Board or its designee. The Executive shall devote his entire working time, attention and energy exclusively to the business of the Company and shall cooperate fully with the Board in the advancement
of the best interests of the Company. The Executive agrees not to engage in any activities outside of the scope of the Executive’s employment that would detract from, or interfere with, the fulfillment of his responsibilities or duties under
this Agreement. The Executive agrees that the Executive will not serve as a director or the equivalent position of any company or entity, except for not-for-profit entities, and will not render services of a business, professional or commercial
nature to any other person or firm, except for not-for-profit entities without the prior written consent of the Board, which consent shall not be unreasonably withheld. If elected as a director of the Company, the Executive agrees to fulfill the
duties of such offices without additional compensation. 
 5. Expenses. Subject to compliance by the Executive with such policies
regarding expenses and expense reimbursement as may be adopted from time to lime by the Company, the Executive is authorized to incur reasonable expenses in the performance of his duties hereunder in furtherance of the business and affairs of the
Company, and the Company will reimburse the Executive for all such reasonable expenses, upon the presentation by the Executive of an itemized account satisfactory to the Company in substantiation of such expenses when claiming reimbursement.

 6. Employee Benefits; Vacations. The Executive shall be eligible to participate in such life insurance, medical and other employee
benefit plans of the Company that may be in effect from time to time, to the extent he is eligible under the terms of those plans, on the same basis as other similarly-situated executive officers of the Company. The Company may from time to time
modify or eliminate any or all benefits extended or provided in its sole discretion. The Executive shall be entitled to paid vacations in accordance with the policies of the Company in effect from time to time, as determined by the Board.

 7. Termination. Upon termination of the Executive’s employment, the Executive will be entitled to any earned but unpaid base
salary and bonus as well as the following additional benefits: 
 (a) In the event that the Executive’s employment is
terminated by the Company for reasons other than Cause (as such term is defined in Section 11 below) or in the event the Executive resigns his employment for Good Reason (as defined in Section 11 below), the Executive will be
provided a severance package with continuation of salary and benefits and, at the discretion of the Board, prorated bonus to the target level. Such severance package will be paid for a period of nine (9) months from the date of termination. The
Executive’s severance will be subject to set off in the event that the Executive obtains other employment during such severance period. 
  

 2 








 (b) In the event that the Executive’s employment is terminated for Cause or the
Executive resigns without Good Reason, the Executive will not be entitled to a severance package. 
 (c) In the event that the
Executive’s employment is terminated by reason of his death or Disability (as such term is defined in Section 11 below) the Executive or his estate will be provided a severance package with continuation of salary and benefits and,
at the discretion of the Board, prorated bonus to the target level. Such severance package will be paid for a period of six (6) months from the date of termination. 
 (d) Pursuant to tax regulations, with respect to any incentive stock options the Executive may be granted, in the event that the
Executive’s employment with the Company is terminated for any reason, (i) the Executive will have 90 days to exercise the vested portion of such stock options or they will be forfeited and (ii) any unvested stock options as of such
date of termination shall be cancelled, provided, however, that if the Executive’s employment terminates by reason of death or disability, and in all events in the case of nonqualified stock options, the Executive or the Executive’s
personal representatives will have twelve (12) months in which to exercise such vested stock options.

Notwithstanding any termination of the Executive’s employment for any reason (with or without Cause), the Executive will continue to be bound by the provisions of the Confidentiality Agreement (as defined below). 
 (f) All payments and benefits provided pursuant to Sections 7(a) and (c) shall be conditioned upon the Executive’s
execution and non-revocation of a general release substantially in the form attached hereto as Exhibit A at the time of termination. The Executive’s refusal to execute a general release shall constitute a waiver by the Executive of
any and all benefits referenced in Sections 7(a) an (c). The Company will not be obligated to continue any such payments to the Executive under Sections 7(a) and (c) in the event the Executive materially breaches the terms of
this Agreement or the Confidentiality Agreement (as defined below).

the Company and any other materials or information related to the Company, including all work product, whether finished or unfinished, prepared or produced by the Executive for the benefit of the Company under this Agreement.

 Amendment to Employment Agreement 
 This FIRST AMENDMENT TO EMPLOYMENT AGREEMENT dated as of February 7, 2007 is between Aegerion Pharmaceuticals, Inc., a Delaware corporation (the “Company”), and William H. Lewis (the
“Executive”). 
 WHEREAS, the Executive is currently employed as a senior executive of the Company under an Employment Agreement dated
April 29, 2005 (the “Agreement”); 
 WHEREAS, Section 7 of the Agreement contains certain severance provisions in respect of the
Executive; and 
 WHEREAS, the parties hereto consider it appropriate that the Agreement be amended pursuant to Section 14 of the Agreement to prevent
adverse tax treatment of severance payments to the Executive upon termination. 
 NOW, THEREFORE, the Company and the Executive agree to the following
amendment to the Agreement. Defined terms used in this Amendment shall have the same meanings as in the Agreement. 
  

	1.	Definitions. Capitalized terms used in this Amendment and not otherwise defined herein shall have the meaning given to such terms in the Agreement. 

  

	2.	Termination. Section 7 of the Agreement is amended adding a new subsection (g) as follows: 

 Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s termination of employment, the Executive is considered
a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Internal Revenue Code of 1986, as amended (the “Code”), and if any payment that the Executive becomes entitled to under this Agreement is
considered deferred compensation subject to interest and additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, then no such payment shall be payable prior to
the date that is the earliest of (i) six months and one day after the Executive’s date of termination, (ii) the Executive’s death, or (iii) such other date as will cause such payment not to be subject to such interest and
additional tax, and the initial payment shall include a catch-up amount covering amounts that would otherwise have been paid during the first six-month period but for the application of this Section 7(g). 
  

	3.	Scope of Amendment. Except as expressly set forth in this Amendment, the Agreement remains in effect without modification. 

  

	4.	Counterparts. This Amendment may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by different parties hereto in separate
counterparts, each of which when executed shall be deemed to be an original but all of which when taken together shall constitute one and the same agreement. 








 IN WITNESS WHEREOF, the Executive and Company have executed this Amendment as of the date set forth above.
