engaged in conduct that could constitute Cause hereunder, the Company may, in its sole and absolute discretion, suspend Employee from performing Employee’s duties hereunder, and in no event shall any such suspension constitute an event pursuant
to which Employee may terminate employment with Good Reason or otherwise constitute a breach hereunder; provided, that no such suspension shall alter the Company’s obligations under this Agreement during such period of suspension.

 (k) “Release of Claims” shall mean a separation agreement in a form acceptable to the Company under which

 Section 3. Position, Duties, and Responsibilities; Place of Performance. 

(a) Position, Duties, and Responsibilities. During the Term, Employee shall be employed and serve as President—Global of the
Company (together with such other position or positions consistent with Employee’s title or as the Company shall specify from time to time) and shall have such duties and responsibilities commensurate therewith, and such other duties as may be
assigned and/or prescribed from time to time by the Chief Executive Officer and/or the Board. 
 (b) Performance.
Employee shall devote his full business time, attention, skill, and best efforts to the performance of his duties under this Agreement and shall not engage in any other business or occupation during the Term, including, without limitation, any
activity that (x) conflicts with the interests of the Company, (y) interferes with the proper and efficient performance of Employee’s duties for the Company, or (z) interferes with Employee’s exercise of judgment in the
Company’s best interests. Notwithstanding the foregoing, nothing herein shall preclude Employee from (i) serving, with the prior written consent of the Board, as a member of the boards of directors or advisory boards (or their equivalents
in the case of a non-corporate entity) of non-competing businesses and charitable organizations, (ii) engaging in charitable activities and community affairs, and (iii) managing Employee’s personal investments and affairs;
provided, however, that the activities set out in clauses (i), (ii), and (iii) shall be limited by Employee so as not to interfere, individually or in the aggregate, with the performance of Employee’s duties and
responsibilities hereunder. Employee represents that he has provided the Company with a comprehensive list of all outside professional activities with which he is currently involved or reasonably expects to become involved. In the event that, during
his employment by the Company, the Employee desires to engage in other outside professional activities, not included on such list, Employee will first seek written approval from the CEO or President and such approval shall not be unreasonably
withheld. 
 Section 4. Compensation. 
 (a) Base Salary. In exchange for Employee’s satisfactory performance of his duties and responsibilities, Employee initially shall be paid a bi-weekly Base Salary of $15,385 ($400,000 on an
annualized basis), payable in accordance with the regular payroll practices of the Company. All payments in this Agreement are on a gross, pre-tax basis and shall be subject to all applicable federal, state and local withholding, payroll and other
taxes. 
 (b) Bonus. In addition to the Base Salary, Employee will be eligible for the following bonus compensation:

 (i) Target Bonus: Employee will be eligible to earn an annual target bonus of up to 40% of his Base
Salary (the “Target Bonus”), prorated in 2012 to reflect his start date. There is an overachievement component to this bonus target, as determined by the Board and Employee’s manager in their sole discretion. The actual amount
of such bonus, if any, will be determined by the Board and Employee’s manager in their sole discretion, based upon Company performance, Employee’s achievement of a series of performance milestones, and any other factors that the Board, in
its discretion, deem appropriate. Please note that Employee’s achievement of such milestones, as well as the amount of any bonus, shall be determined by the Board and Employee’s manager in their sole discretion. Typically, bonuses, if any,
are paid out no later than March 15 of the year following the applicable bonus year. Please also note that Employee must be employed by Aegerion at the time of any such bonus payment in order to be eligible for any such payment.

 (c) Stock Options/Equity Grants. Subject to Board approval, the Company will offer to
Employee the option (the “Option Award”) to purchase 220,000 shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”). The Option Award shall have an exercise price equal to the
fair market value of the Common Stock on the date of grant (as determined by the Board or Compensation Committee thereof). The Option Award shall be subject to vesting and shall be issued pursuant to the terms of the Company’s 2010 Stock Option
and Incentive Plan (or a successor plan, if any) and subject to the terms of a stock option agreement thereunder (collectively the “Equity Documents”). The vesting schedule for Employee’s Option Award will be the vesting
schedules outlined in the Equity Documents (i.e., the option to purchase 220,000 shares will vest over four years in equal monthly installments commencing immediately upon the grant). The full terms and conditions related to the Option Award and the
option grants set forth below shall be set forth in the Equity Documents and to the extent that there is any inconsistency between this Agreement and the Equity Documents, the Equity Documents shall control. 

In addition to the Option Award, Employee will be eligible for two “milestone” grants, as determined by and subject to the
approval of the Board in its sole discretion, as follows: 
 (i) Upon meeting or exceeding the Company’s
2012 Profit and Loss corporate goal (both the goal and the achievement to be determined by the Board in its sole discretion), Employee will be granted an option to purchase an additional 15,000 shares of the Company’s common stock under the its
then-existing stock option program, subject to approval by the Company’s Board; and. 
 (ii) Upon meeting or
exceeding the Company’s 2013 Profit and Loss corporate goal (both the goal and the achievement to be determined by the Board in its sole discretion), Employee will be granted an option to purchase an additional 15,000 shares of the
Company’s common stock under the then-existing stock option program, subject to approval by the Company’s Board. 

Section 5. Employee Benefits. 
 During the Term, Employee shall be eligible to participate in health insurance and other benefits provided generally to similarly situated employees of the Company, subject to the terms and conditions of
the applicable benefit plans (which shall govern). Employee also shall be eligible for the same number of holidays and vacation days as well as any other benefits, in each case as are generally allowed to similarly situated employees of the Company
in accordance with the Company policy as in effect from time to time. Nothing contained herein shall be construed to limit the Company’s ability to amend, suspend, or terminate any employee benefit plan or policy at any time without providing
Employee notice, and the right to do so is expressly reserved. 
 Section 6. Reimbursement of Business Expenses; Relocation
Assistance. 
 (a) Business Expenses. During the Term of Employment, the Company shall pay (or promptly reimburse
Employee) for documented, out-of-pocket expenses reasonably incurred by Employee in the course of performing his duties and responsibilities hereunder, which are consistent with the Company’s policies in effect from time to time with respect to
business expenses, subject to the Company’s requirements with respect to reporting of such expenses. 

  
 4 








 (b) Relocation Assistance. In addition to the Company’s general business expense
reimbursement policy summarized above, the Company shall reimburse Employee up to a maximum amount of $100,000 (less applicable taxes) in expenses that directly relate to Employee’s relocation from Switzerland to Massachusetts, provided that
Employee submits supporting documentation in such form and containing such information as the Company may request. This allowance must be used within twenty-four months of the Effective Date. 

(c) Eligibility for Reimbursement of Previously Paid Relocation Expenses. If Employee is required to repay to his former employer,
Shire Human Genetic Therapies, a division of Shire, those relocation expenses that previously were provided to Employee, then Employee will be eligible to receive a one-time payment of up to $37,500 (less applicable taxes), as determined by Company.
This amount will be paid to Employee within a reasonable time (no greater than 30 days) after he has provided satisfactory documentation to the Company that evidences his repayment of such expenses. If Employee resigns or Aegerion terminates his
employment for Cause within 12 months of Aegerion making this payment to you, then Employee agrees to repay to Aegerion a prorated, net amount, as determined by Aegerion in its sole discretion, within 30 days of the termination of your employment.

 Section 7. Termination of Employment. 
 (a) General. Employee’s employment with the Company shall terminate upon the earliest to occur of: (i) Employee’s death, (ii) a termination by reason of a Disability,
(iii) a termination by the Company with or without Cause, and (iv) a termination by Employee with or without Good Reason. Notwithstanding anything herein to the contrary, the payment (or commencement of a series of payments) hereunder of
any nonqualified deferred compensation (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Employee has also undergone a “separation from service” as defined in Treas.
Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Employee’s termination of employment hereunder) shall be paid (or commence to be paid) to Employee on the schedule set forth in this
Section 7 as if Employee had undergone such termination of employment (under the same circumstances) on the date of Employee’s ultimate “separation from service.” 

(b) Termination Due to Death or Disability. Employee’s employment under this Agreement shall terminate automatically upon
Employee’s death. The Company also may terminate Employee’s employment immediately upon the occurrence of a Disability, such termination to be effective upon Employee’s receipt of written notice of such termination. In the event of
Employee’s termination as a result of Employee’s death or Disability, Employee or Employee’s estate or beneficiaries, as the case may be, shall be entitled only to the Accrued Obligations, and Employee shall have no further rights to
any compensation or any other benefits under this Agreement. 
 (c) Termination by the Company with Cause. 

(i) The Company may terminate Employee’s employment at any time with Cause, effective upon Employee’s receipt of
written notice of such termination; provided, however, that with respect to any Cause termination relying on clause (i) or (ii) of the definition of Cause set forth in Section 1(d) hereof, to the extent that such act or
acts or failure or failures to act are curable, Employee shall be given ten (10) days’ written notice by the Company of its intention to terminate him with Cause, such notice to state the act or acts or failure or failures to act that
constitute the grounds on which the proposed termination with Cause is based, and such termination shall be effective at the expiration of such ten (10) day notice period unless Employee has fully cured such act or acts or failure or failures
to act, to the Company’s complete satisfaction, that give rise to Cause during such period. 

  
 5 








 (ii) In the event that the Company terminates Employee’s employment
with Cause, Employee shall be entitled only to the Accrued Obligations. Following such termination of Employee’s employment with Cause, except as set forth in this Section 7(c)(ii), Employee shall have no further rights to any compensation
or any other benefits under this Agreement. For the avoidance of doubt, Employee’s sole and exclusive remedy upon a termination of employment by the Company with Cause shall be receipt of the Accrued Obligations. 

(d) Termination by the Company without Cause. The Company may terminate Employee’s employment at any time without Cause,
effective upon Employee’s receipt of written notice of such termination. In the event that Employee’s employment is terminated by the Company without Cause (other than due to death or Disability) and provided that he fully executes an
effective Release of Claims as described in Section 7(g), Employee shall be eligible for: 
 (i) The Accrued
Obligations; 
 (ii) The Severance Benefits; and 

(iii) Acceleration of the vesting of 100% of Employee’s then outstanding unvested equity awards, such that all
unvested equity awards vest and become fully exercisable or non-forfeitable as of the Date of Termination; provided that such termination without Cause and the Date of Termination occurs within eighteen (18) months after a Sale
Event (the “Accelerated Equity Benefit”), in which case Employee shall have ninety (90) days from the Date of Termination to exercise the vested equity awards. 
 Notwithstanding the foregoing, the Severance Benefits shall immediately terminate, and the Company shall have no further obligations to Employee with respect thereto, in the event that Employee breaches
any provision of the Confidentiality Agreement or the Release of Claims. Any such termination of payment or benefits shall have no effect on the Release of Claims or any of Employee’s post-employment obligations to the Company. Following such
termination of Employee’s employment by the Company without Cause, except as set forth in this Section 7(d), Employee shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt,
Employee’s sole and exclusive remedy upon a termination of employment by the Company without Cause shall be receipt of the Severance Benefits (and, in the case of such a termination within eighteen (18) months after a Sale Event, the
Accelerated Equity Benefit), subject to his execution of the Release of Claims, and the Accrued Obligations. 
 In addition, the Severance
Benefit set forth in Section 1(l)(i) shall be reduced dollar for dollar by any compensation Employee receives from another employer during the Severance Term. Employee agrees to give prompt notice of any employment during the Severance term and
promptly shall respond to any reasonable inquiries concerning her professional activities. If the Company makes overpayments of Severance Benefits, Employee promptly shall return any such overpayments to the Company and/or hereby authorizes
deductions from future Severance Benefit amounts. The foregoing shall not create any obligation on the Employee’s part to seek re-employment after the Date of Termination. 

(e) Termination by Employee with Good Reason. Employee may terminate his employment with Good Reason by providing the Company
thirty (30) days’ written notice setting forth in reasonable specificity the event that constitutes Good Reason, which written notice, to be effective, must be provided to the Company within sixty (60) days of the occurrence of such
event. During such thirty (30) day notice period, the Company shall have a cure right (if curable), and if not cured within such period, Employee’s termination will be effective upon the expiration of such cure period, and Employee


  
 6 








 
shall be entitled to the same payments and benefits as provided in Section 7(d) hereof for a termination by the Company without Cause, subject to the same conditions on payment and benefits
as described in Section 7(d) hereof. Following such termination of Employee’s employment by Employee with Good Reason, except as set forth in this Section 7(e), Employee shall have no further rights to any compensation or any other
benefits under this Agreement. For the avoidance of doubt, Employee’s sole and exclusive remedy upon a termination of employment with Good Reason shall be receipt of the Severance Benefits (and, in the case of such a termination within eighteen
(18) months after a Sale Event, the Accelerated Equity Benefit), subject to his execution of the Release of Claims, and the Accrued Obligations. 
 (f) Termination by Employee without Good Reason. Employee may terminate his employment without Good Reason by providing the Company thirty (30) days’ written notice of such termination.
In the event of a termination of employment by Employee under this Section 7(f), Employee shall be entitled only to the Accrued Obligations. In the event of termination of Employee’s employment under this Section 7(f), the Company
may, in its sole and absolute discretion, by written notice accelerate such date of termination without changing the characterization of such termination as a termination by Employee without Good Reason. Following such termination of Employee’s
employment by Employee without Good Reason, except as set forth in this Section 7(f), Employee shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt, Employee’s sole and
exclusive remedy upon a termination of employment by Employee without Good Reason shall be receipt of the Accrued Obligations. 
 (g) Release. Notwithstanding any provision herein to the contrary, the payment of the Severance Benefits pursuant to subsection (d) or (e) of this Section 7 (other than the Accrued
Obligations) shall be conditioned upon Employee’s execution, delivery to the Company, and non-revocation of the Release of Claims (and the expiration of any revocation period contained in such Release of Claims) in accordance with the time
limits set forth therein. If Employee fails to execute the Release of Claims in such a timely manner, or timely revokes Employee’s acceptance of such release following its execution, Employee shall not be entitled to any of the Severance
Benefits. Further, to the extent that any of the Severance Benefits constitutes “nonqualified deferred compensation” for purposes of Section 409A of the Code, any payment of any amount or provision of any benefit otherwise scheduled
to occur prior to the thirty-fifth (35th) day
following the date of Employee’s termination of employment hereunder, but for the condition on executing the Release of Claims as set forth herein, shall not be made until the first regularly scheduled payroll date following such thirty-fifth
(35th) day, after which any remaining Severance
Benefits shall thereafter be provided to Employee according to the applicable schedule set forth herein.  
 Section 8.
Confidentiality Agreement; Cooperation. 
 (a) Confidentiality Agreement. As a condition of Employee’s
employment with the Company under the terms of this Agreement, Employee shall execute and deliver to the Company the Confidentiality Agreement, in the form attached hereto as Exhibit A. The parties hereto acknowledge and agree that this Agreement
and the Confidentiality Agreement shall be considered separate contracts. In addition, Employee represents and warrants that she shall be able to and will perform the duties of this position without utilizing any confidential and/or proprietary
information that Employee may have obtained in connection with employment with any prior employer, and that she shall not (i) disclose any such information to Aegerion, or (ii) induce any Aegerion employee to use any such information, in
either case in violation of any confidentiality obligation, whether by agreement or otherwise. 

  
 7 








 (b) Litigation and Regulatory Cooperation. During and after Employee’s
employment, Employee shall cooperate fully with the Company in the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that
transpired while the Company employed Employee, provided, that the Employee will not have an obligation under this paragraph with respect to any claim in which the Employee has filed directly against the Company or related persons or entities. The
Employee’s full cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually
convenient times. During and after Employee’s employment, Employee also shall cooperate fully with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or
review relates to events or occurrences that transpired while Employee was employed by the Company, provided Employee will not have any obligation under this paragraph with respect to any claim in which Employee has filed directly against the
Company or related persons or entities. The Company shall reimburse Employee for any reasonable out-of-pocket expenses incurred in connection with Employee’s performance of obligations pursuant to this Section 8(b). 

Section 9. Taxes. 
 The Company may withhold from any payments made under this Agreement all applicable taxes, including but not limited to income, employment, and social insurance taxes, as shall be required by law.
Employee acknowledges and represents that the Company has not provided any tax advice to him in connection with this Agreement and that Employee has been advised by the Company to seek tax advice from Employee’s own tax advisors regarding this
Agreement and payments that may be made to him pursuant to this Agreement, including specifically, the application of the provisions of Section 409A of the Code to such payments. The Company shall have no liability to Employee or to any other
person if any of the provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A but that do not satisfy an exemption from, or the conditions of, that section. 

Section 10. Additional Section 409A Provisions. 
 Notwithstanding any provision in this Agreement to the contrary: 
 (a) If at the
time of the Employee’s separation from service within the meaning of Section 409A of the Code, the Company determines that the Employee is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code,
then to the extent any payment or benefit that the Employee becomes entitled to under this Agreement on account of the Employee’s separation from service would be considered deferred compensation subject to the 20 percent 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, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (i) six
months and one day after the Employee’s separation from service, or (ii) the Employee’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering
amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. 

(b) Each payment in a series of payments hereunder shall be deemed to be a separate payment for purposes of Section 409A of the
Code. Neither the Company nor Employee shall have the right to accelerate or defer the delivery of any such payments except to the extent specifically permitted or required by Section 409A. 

  
 8 








 (c) To the extent that any right to reimbursement of expenses or payment of any benefit
in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by the Company no later than the last day of the taxable year
following the taxable year in which such expense was incurred by Employee, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible
for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be
violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect. 

(d) To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation”
under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Employee’s termination of employment, then such payments or benefits shall be payable only upon the Employee’s “separation from
service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h). 

(e) The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any
provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. The parties agree that this
Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder
without additional cost to either party. While the payments and benefits provided hereunder are intended to be structured in a manner to avoid the implication of any penalty taxes under Section 409A of the Code, in no event whatsoever shall the
Company or any of its affiliates be liable for any additional tax, interest, or penalties that may be imposed on Employee as a result of Section 409A of the Code or any damages for failing to comply with Section 409A of the Code (other
than for withholding obligations or other obligations applicable to employers, if any, under Section 409A of the Code). 

Section 11. Successors and Assigns. 
 (a) The Company. This Agreement shall inure to the benefit of the Company and its respective successors and assigns. This Agreement may be assigned by the Company without Employee’s prior
consent. 
 (b) Employee. Employee’s rights and obligations under this Agreement shall not be transferable by
Employee by assignment or otherwise, without the prior written consent of the Company; provided, however, that if Employee shall die, all amounts then payable to Employee hereunder shall be paid in accordance with the terms of this
Agreement to Employee’s devisee, legatee, or other designee, or if there be no such designee, to Employee’s estate.

 Section 12. Waiver and Amendments. 

Any waiver, alteration, amendment, or modification of any of the terms of this Agreement shall be valid only if made in writing and signed
by each of the parties hereto; provided, however, that any such waiver, alteration, amendment, or modification must be consented to on the Company’s behalf by the Board. No waiver by either of the parties hereto of their rights
hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such waiver specifically states that it is to be construed as a continuing waiver. 

Section 13. Severability. 
 If any covenants or such other provisions of this Agreement are found to be invalid or unenforceable by a final determination of a court of competent jurisdiction, (a) the remaining terms and
provisions hereof shall be unimpaired, and (b) the invalid or unenforceable term or provision hereof shall be deemed replaced by a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid
or unenforceable term or provision hereof. 
 Section 14. Governing Law and Jurisdiction. This is a Massachusetts
contract and shall be construed under and be governed in all respects by the laws of the Commonwealth of Massachusetts without giving effect to the conflict of laws principles of such state. With respect to any disputes concerning federal law, such
disputes shall be determined in accordance with the law as it would be interpreted and applied by the United States Court of Appeals for the First Circuit. To the extent that any court action is initiated to enforce this Agreement, the parties
hereby consent to the jurisdiction of the state and federal courts of the Commonwealth of Massachusetts. Accordingly, with respect to any such court action, Employee (a) submits to the personal jurisdiction of such courts; (b) consents to
service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process. 

Section 15. Notices. 
 (a) Place of Delivery. Every notice or other communication relating to this Agreement shall be in writing, and shall be mailed to or delivered to the party for whom or which it is intended at such
address as may from time to time be designated by it in a notice mailed or delivered to the other party as herein provided; provided, that unless and until some other address be so designated, all notices and communications by Employee to the
Company shall be mailed or delivered to the Company at its principal executive office, and all notices and communications by the Company to Employee may be given to Employee personally or may be mailed to Employee at Employee’s last known
address, as reflected in the Company’s records. 
 (b) Date of Delivery. Any notice so addressed shall be deemed to
be given or received (i) if delivered by hand, on the date of such delivery, (ii) if mailed by courier or by overnight mail, on the first business day following the date of such mailing, and (iii) if mailed by registered or certified
mail, on the third business day after the date of such mailing. 
 Section 16. Section Headings. 

The headings of the sections and subsections of this Agreement are inserted for convenience only and shall not be deemed to constitute a
part thereof or affect the meaning or interpretation of this Agreement or of any term or provision hereof.

 Section 17. Entire Agreement.
