(a) Initial Closing.

(i) The initial closing of the sale and purchase of the Notes (the “Initial Closing”) shall be held at such date and time (the “Initial Closing Date”) as the Company and Required Purchasers (as defined below) shall agree. At the Initial Closing the Purchasers will purchase an aggregate of at least $2,500,000.00 of Notes as follows: (A) each Purchaser shall deliver to the Company by check or wire transfer of immediately available funds such Purchaser’s Initial Loan Amount set forth opposite each such Purchaser’s name under the heading “Initial Loan Amount” on the Schedule of Purchasers attached hereto (such Purchaser’s “Initial Loan Amount”) and (B) the Company shall issue and deliver to each Purchaser a Note in favor of such Purchaser in the corresponding principal amount equal to such Purchaser’s Initial Loan Amount.

(ii) After the Initial Closing, subsequent sale(s) and purchase(s) of Notes may occur from time to time (each such closing an “Additional Initial Closing” and together with the Initial Closing, the “Initial Closings”) to one or more purchasers (the “Additional Purchasers”) on the same terms and conditions as those contained in this Agreement, provided that (A) in no event shall the aggregate principal amount of all Notes sold at the Initial Closings exceed $3,814,759.51, (B) any Additional Initial Closing(s) shall be consummated no later than twenty-one (21) days after the Initial Closing Date (the date of any Additional Initial Closing shall be referred to herein as an “Additional Initial Closing Date”), (C) each Additional Purchaser shall become a party to the Transaction Agreements, and (D) each of the Purchasers is given prompt notice of the consummation of any such Additional Initial Closing. The Schedule of Purchasers to this Agreement shall be updated to reflect the aggregate principal amount of any Notes purchased at each such Additional Initial Closing and the parties purchasing such Notes. The Schedule of Purchasers shall also be updated to reflect the Additional Purchaser(s)’ pro rata share of the $5,000,000.00 in aggregate principal amount of Notes to be purchased at any Subsequent Closing, as set forth below. At any Additional Initial Closing, the representations and warranties of the Company in Section 3 hereof (and the Schedule of Exceptions delivered to the Purchasers in the Initial Closing (the “Schedule of Exceptions”)) shall be deemed to speak as of the date of the Additional Initial Closing and the Company shall, if necessary, update the Schedule of Exceptions as of the Additional Initial Closing.

(b) Subsequent Closing(s). Subject to the pay-to-play and automatic conversion provisions of Section 2(h), a subsequent sale and purchase of the Notes (the “Subsequent Closing”) shall occur in one subsequent closing, if at all, at such time as the Required Purchasers unanimously determine, such determination currently expected to be made upon the later of (i) the completion of a reasonable review by the Purchasers with the Company’s Scientific Advisory Board of clinical data from the following studies: “A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Safety and Efficacy of the Combination of AEGR-733 (formerly BMS 201038) and Atorvastatin 20 Mg vs. Monotherapy in Subjects with Moderate Hypercholesterolemia,” “A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate Low Doses of the MTP-Inhibitor AEGR-733 on Hepatic Fat Accumulation as Measured by Magnetic Resonance Spectroscopy,” and “A Randomized, Double-Blind, Comparator-Controlled, Parallel-Group Study to Evaluate the Safety and Efficacy of the Combination of AEGR-733 and Atorvastatin 20 Mg vs. Atorvastatin Monotherapy in Subjects with Moderate Hypercholesterolemia,” such review currently expected to take place at or around the same dates as the American Heart Associations Scientific Sessions in November 2008, but in any event not to exceed three (3) weeks following the release of such data to the Required Purchasers; and (ii) such time as the Company’s operating capital falls below $4,000,000.00. The Subsequent Closing shall be held at such date and time, at least 10 days after written notice to the Purchasers (the “Subsequent Closing Date”), as the Company and the Required Purchasers shall agree. At the Subsequent Closing, the Purchasers shall purchase an aggregate of up to $5,000,000.00 of Notes as follows: (i) each Purchaser shall deliver to the Company by check or wire transfer of immediately available funds an amount equal to such Purchaser’s pro rata share (determined in proportion to such Purchaser’s share of all Notes purchased at the Initial Closings) of the aggregate principal amount of all Notes to be purchased at the Subsequent Closing and set forth opposite each such Purchaser’s name under the heading “Subsequent Loan Amount” on the Schedule of Purchasers attached hereto, as amended from time to time in accordance with this Agreement (such Purchaser’s “Subsequent Loan Amount”), and (ii) the Company shall issue and deliver to each Purchaser a Note in favor of such Purchaser in the corresponding principal amount equal to such Purchaser’s Subsequent Loan Amount.

SENIOR SUBORDINATED CONVERTIBLE PROMISSORY NOTE


$[ ]		June 14, 2010

FOR VALUE RECEIVED, Aegerion Pharmaceuticals, Inc., a Delaware corporation (the “Company”), hereby promises to pay to the order of [ ] (or its successors or assigns, the “Holder”), the principal amount of [ ] ($[ ]), plus interest in arrears from and including the date hereof on the principal balance from time to time outstanding, accruing daily, at a rate per annum equal to eight percent (8%) for the time period beginning on the date hereof and ending on the Maturity Date. This Senior Subordinated Convertible Promissory Note (this “Note”) may not be prepaid in whole or in part without the written consent of the Required Purchasers. For avoidance of doubt, no interest payments shall be due prior to the earlier of: (i) Maturity as set forth in Section 2 of this Note, (ii) acceleration due to an Event of Default (defined below), or (iii) conversion of the Note as set forth in Sections 3, 4 and 5 of this Note, as the case may be. Interest shall be calculated on the basis of actual number of days elapsed over a year of 365 days. Notwithstanding any other provision of this Note, the Holder hereof does not intend to charge and the Company shall not be required to pay any interest or other fees or charges in excess of the maximum interest permitted by applicable law, and any payments in excess of such maximum shall be refunded to the Company or credited to reduce principal hereunder. All payments received by the Holder hereunder will be applied first to costs of collection, if any, then to interest and the balance to principal.

This Note is one of a series of Senior Subordinated Convertible Promissory Notes of like tenor (collectively, the “Notes”) to be issued by the Company pursuant to the terms of that certain Third Amended and Restated Note Purchase Agreement dated as of June 14, 2010 (as may be amended and/or restated from time to time, the “Purchase Agreement”) among the Company and the purchasers set forth on the Schedule I thereto (the “Schedule of Purchasers”). Capitalized terms not otherwise defined herein shall have the respective meanings ascribed to such terms in the Purchase Agreement. By acceptance of this Note, the Holder and the Company each hereby agree that each of the Notes shall rank equally and ratably without priority over one

another, and the Company covenants and agrees that none of the Notes shall be paid, in whole or in part, unless a reasonably equivalent, pro rata payment is made with respect to all other Notes so as to maintain as near as possible the amount of the debt owing under the Notes pro rata according to the respective balances owed as of the date immediately prior to such payment. This Note will be registered on the books of the Company or its agent as to principal and interest. Any transfer of this Note may be effected only by surrender of this Note to the Company and reissuance of a new Note to the transferee. Payments of principal and interest will be made by wire transfer in immediately available United States funds transferred to the account of the Holder, which account information shall have been furnished to the Company by the Holder for that purpose.

Subordination. This Note is subordinate and junior in right of payment to the prior payment in full of all obligations of the Company under that certain Loan and Security Agreement between the Company and Hercules Technology Growth Capital, Inc. (“Hercules”) dated March 20, 2007, all promissory notes issued by the Company to Hercules pursuant thereto and any other such obligations agreed to in the Third Amended and Restated Subordination Agreement among the purchasers set forth on Schedule I to the Purchase Agreement, the Company and Hercules dated as of June 14, 2010.

Maturity. The entire outstanding principal balance hereof, together with all accrued and unpaid interest thereon, shall be due and payable (i) automatically upon the occurrence of an Event of Default (as defined below) specified in Section 6.1(c), 6.1(d), 6.1(e) or 6.1(f), or (ii) if occurring earlier than any Event of Default described in (i) above, upon demand made in writing by the Required Purchasers at any time upon the earlier of (a) December 31, 2011, unless such date is extended to a later date by an agreement in writing between the Company and the Required Purchasers (such original date or such later date, the “Maturity Date”), (b) a Sale of the Company (as defined below) or (c) the occurrence of an Event of Default specified in Section 6.1(a) or 6.1(b). In order to extend the Maturity Date, the Required Purchasers and the Company shall agree in writing to extend the Maturity Date (an “Extension Agreement”), and the Extension Agreement shall specify the date they elect to extend the Maturity Date. Following such Extension Agreement, every reference in the Note Purchase Agreement and the Notes to the Maturity Date shall be deemed to refer to the Maturity Date set forth in the Extension Agreement.

Reserved

Conversion upon Equity Sale.

Qualified Equity Sale. Immediately upon the closing of a Qualified Equity Sale (as defined below), the Note Balance shall automatically be converted into fully paid and non-assessable shares of New Stock (as defined below). The type and class of capital stock of the Company to be issued to the Holder of this Note upon conversion pursuant to this Section 5(a) (and the rights and privileges of the Holder thereof) shall be identical to the type and class of the capital stock issued by the Company in connection with the Qualified Equity Sale (the “New Stock”). Upon conversion of this Note pursuant to this Section 5(a), subject to the provisions of Section 5(c) hereof, the holder of this Note shall be entitled to receive a number of shares of New Stock determined by dividing (A) the Note Balance as of the Investor Conversion Date (as defined below) by (B) an amount equal to eighty-five percent (85%) of the price per share of New Stock paid by the investors in connection with the Qualified Equity Sale (the “New Stock Price”). A “Qualified Equity Sale” shall mean and include the sale of shares of capital stock of the Company (other than a sale of shares of the Company’s Common Stock, $0.001 par value per share (the “Common Stock”), or other securities to officers, directors or employees of, or consultants to, the Company in connection with their provision of services to the Company) in one transaction or series of related transactions, which sale or sales, including without limitation any initial public offering, result in gross proceeds to the Company, not including any Note Balance converted to New Stock, of at least Ten Million Dollars ($10,000,000).

Conversion upon Alternative Equity Sale. In the event that the Company intends to consummate an Alternative Equity Sale (as defined below), the Company shall send written notice at least ten (10) business days prior to the closing of such Alternative Equity Sale to the Holder hereof (the “Company Notice”), which Company Notice shall describe the Alternative Equity Sale in reasonable detail. Upon written notice to the Company delivered prior to the closing of such Alternative Equity Sale, the Required Purchasers may elect to convert the Note Balance of all, but not less than all, of the Notes issued to all Purchasers under the Purchase Agreement then outstanding into fully paid and non-assessable shares of Alternative Stock (as defined below); provided that if the Required Purchasers do not so elect, then the Holder hereof may, by written notice to the Company not more than five (5) business days following receipt by the Holder of the Company Notice, elect to convert all or part of the Note Balance into fully paid and non-assessable shares of Alternative Stock. The type and class of capital stock of the Company to be issued to the holder of this Note upon conversion pursuant to this Section 5(b) (and the rights and privileges of the holders thereof) shall be identical to the type and class of the capital stock issued by the Company in connection with the Alternative Equity Sale (the “Alternative Stock”). Upon conversion of this Note pursuant to the provisions of this Section 5(b), subject to the provisions of Section 5(c) hereof, the Holder of this Note shall be entitled to receive a number of shares of Alternative Stock determined by dividing (A) the Note Balance to be converted by (B) an amount equal to eighty five percent (85%) of the price per share of Alternative Stock paid by the purchasers of such equity securities in connection with the Alternative Equity Sale (the “Alternative Stock Price”). “Alternative Equity Sale” shall mean and include any sale of shares of capital stock of the Company (other than a sale of shares of Common Stock or other securities to officers, directors or employees of, or consultants to, the Company in connection with their provision of services to the Company) in one transaction or series of related transactions, which sale or sales result in gross proceeds to the Company of less than Ten Million Dollars ($10,000,000).

Fractional Shares. No fractional shares of capital stock of the Company shall be issued upon conversion of this Note. In lieu of any fractional shares to which the holder would otherwise be entitled, the Company shall pay cash equal to such fraction multiplied by the New Stock Price or the Alternative Stock Price, as applicable.

Mechanics of Conversion; Investor Sale.

Upon the closing (the “Investor Conversion Date”) of a Qualified Equity Sale or an Alternative Equity Sale if either (y) the Required Purchasers have elected to convert the Note Balance of all Notes then outstanding or (z) the Holder hereof has elected to convert the Note Balance of this Note (each being referred to herein as an “Investor Sale”), this Note, or any portion hereof, as applicable, shall be converted automatically without any further action by the holder and whether or not this Note is surrendered to the Company or the transfer agent for this Note, provided, however, that the Company shall not be obligated to issue a certificate or certificates evidencing the shares of New Stock or Alternative Stock (each being referred to herein as “Investor Stock”) into which this Note is convertible unless this Note is delivered to the Company, or the holder notifies the Company that the Note has been lost, stolen, or destroyed and executes and delivers an agreement satisfactory to the Company to indemnify the Company from any loss incurred by it in connection therewith and, if the Company so elects, provides an appropriate indemnity.

The Company shall cause notice of the Investor Sale to be mailed to the registered holder of this Note, at such holder’s address appearing in the records of the Company, as promptly as practicable after the Investor Conversion Date. Thereafter, the holder shall surrender this Note at the place designated in such notice, together with a written notice by the holder of this Note stating such holder’s name or the names of his, her or its nominees in which such holder wishes the certificate or certificates for shares of Investor Stock to be issued. If required by the Company, the Note surrendered shall be endorsed or accompanied by a written instrument or instruments of surrender, in form satisfactory to the Company, duly executed by the registered holder or his or its attorney duly authorized in writing.

Upon authorization of the sale of shares of its capital stock in an Investor Sale, for the purpose of effecting the conversion of this Note as provided in Section 5(a) or 5(b) hereof, the Company shall have (A) authorized a sufficient number of shares of Investor Stock to effect the conversion of the Note Balance, or any portion thereof, as applicable, (B) reserved such stock as to which the Holder would be entitled upon conversion of such Investor Stock and (C) taken all other actions reasonably requested by the Holder to effect the foregoing. The Company shall take all such reasonable actions as may be necessary to assure that all Investor Stock which may be issuable upon the conversion of this Note and all shares of stock issuable upon conversion or exercise thereof may be issued without violation of any applicable law or governmental regulation.

Immediately upon the Investor Conversion Date, this Note shall be cancelled and no longer be deemed to be outstanding and all rights with respect to this Note shall immediately cease and terminate on the Investor Conversion Date, except only the right of the holder to receive the shares of Investor Stock to which it is entitled as a result of the conversion on the Investor Conversion Date, together with any cash in lieu of fractional shares. Notwithstanding the foregoing, upon the Investor Conversion Date, the Company shall be released from all obligations arising under this Note.

The Company shall pay any and all issue and other taxes that may be payable in respect of any issuance or delivery of shares of Investor Stock upon conversion of this Note pursuant to Section 5(a) or 5(b) hereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Investor Stock in a name other than that of the registered holder of this Note, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Company the amount of any such tax or has established, to the satisfaction of the Company, that such tax has been paid.

any case or proceeding is commenced against the Company to have an order for relief entered against it as debtor or seeking reorganization, arrangement, adjustment, liquidation, dissolution or composition of its structure or its debts under any law relating to bankruptcy, insolvency, reorganization or relief of debtors, or seeking other similar official relief for it or any part of its property, and such case or proceeding (x) results in the entry of an order for relief against it which is not fully stayed within five (5) business days after the entry thereof or (y) is not dismissed within one hundred twenty (120) days of commencement.

Remedies Upon Event of Default. Upon any Event of Default, the Required Purchasers may, by written notice to the Company, declare this Note to be due and payable, whereupon the outstanding principal and accrued interest under this Note shall be immediately due and payable; provided that, in the case of an Event of Default pursuant to any of Sections 6.1(c), 6.1(d), 6.1(e) or 6.1(f), the outstanding principal and accrued interest under this Note shall become due and payable without notice or demand.

Amendment to Amended and Restated Certificate of Incorporation (Initial Closing)

CERTIFICATE OF AMENDMENT

AMENDED AND RESTATED

CERTIFICATE OF INCORPORATION

AEGERION PHARMACEUTICALS, INC.

AEGERION PHARMACEUTICALS, INC., a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the “Corporation”), does hereby certify as follows:

FIRST: That the Board of Directors of the Corporation (the “Board”) duly adopted resolutions in accordance with Section 242 of the General Corporation Law of the State of Delaware (i) proposing an amendment to the Amended and Restated Certificate of Incorporation of the Corporation (the “Certificate of Incorporation”), (ii) declaring such amendment to be advisable and in the best interests of the Corporation, and (iii) directing that such amendment be submitted to and be considered by the stockholders of the Corporation entitled to vote thereon for approval by the affirmative vote of such stockholders. Such resolution proposed to amend the Certificate of Incorporation in the following manner:

1. To increase the number of shares of Common Stock the Corporation shall have authority to issue to from 25,000,000 to 30,000,000 by amending the first paragraph of Article FOURTH to read as follows:

FOURTH: The aggregate number of shares which the Corporation shall have the authority to issue shall be 49,650,000 shares, consisting of 30,000,000 shares of Common Stock, par value $0.001 per share (the “Common Stock”) and 19,650,000 shares of Preferred Stock, par value 0.001 per share (the “Preferred Stock”), of which 13,000,000 shares are designated Series A Convertible Preferred Stock (the “Series A Preferred”) and 6,650,000 shares are designated Series B Convertible Preferred Stock (“Series B Preferred” and together with the Series A Preferred, the “Designated Preferred”).

2. To amend Section B.2(d)(i)(C)(I) of Article Fifth of the Certificate of Incorporation of the Corporation to increase by 253,344 the number of Options included in the definition of “Excluded Securities” by deleting “1,206,809” in part (a) and replacing it with “1,460,153”.

3. To insert the following paragraph as the last paragraph of Section B.2 of Article Fifth of the Certificate of Incorporation of the Corporation:

(f)	Special Mandatory Conversion.

(i) Trigger Event. In the event that any holder of shares of Designated Preferred who is also a holder of 2008 Convertible Notes (as defined below) issued pursuant to the 2008 Note Purchase Agreement (as defined below) (each, a “Note Holder”) does not purchase (together with its Affiliates, as defined in the 2008 Note Purchase Agreement) 100% of such Note Holder’s Subsequent Loan Amount (as defined in the 2008 Note Purchase Agreement) at a Subsequent Closing (as defined in the 2008 Note Purchase Agreement), if any, then each share of Designated Preferred held by such Note Holder shall automatically, and without any further action on the part of such holder, be converted into shares of Common Stock at the conversion ratio determined pursuant to Section B.2(a) of this Article Fifth immediately prior to the consummation of such Subsequent Closing, effective upon, subject to, and concurrently with, the consummation of such Subsequent Closing. For purposes of this Section B.2(f), the number of shares of Designated Preferred held by a Note Holder shall include all shares of Designated Preferred held by Affiliates (as defined in the 2008 Note Purchase Agreement) of such holder. The conversion of Designated Preferred pursuant to this Section B.2(f) is referred to as a “Special Mandatory Conversion”.

(ii) Procedural Requirements. Upon a Special Mandatory Conversion, all shares of Designated Preferred subject to the Special Mandatory Conversion shall be converted automatically without any further action by any holder of such shares and whether or not the certificate or certificates representing such shares are surrendered to the Corporation. All rights with respect to the Designated Preferred converted pursuant to Subsection (i), including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate, except only the rights of the holders thereof, upon surrender of their certificate or certificates therefor (or lost certificate affidavit and agreement), to receive cash in lieu of fractional shares, as provided for in the last sentence of this Subsection (ii). Each holder of Designated Preferred subject to the Special Mandatory Conversion shall surrender the certificate or certificates representing such holder’s shares of Designated Preferred at the office of the Corporation. Thereupon, there shall be issued and delivered to such holder, promptly at such office and in such holder’s name as shown on such surrendered certificate or certificates, a certificate or certificates for the number of shares of Common Stock into which the shares of Designated Preferred surrendered were convertible on the date on which such automatic conversion occurred; provided, however, that the Corporation shall not be obligated to issue a certificate or certificates evidencing the shares of Common Stock into which such shares of Designated Preferred were convertible unless the certificate or certificates representing such shares of Designated Preferred being converted are either delivered to the Corporation, or the holder notifies the Corporation that such certificate or certificates have been lost, stolen, or destroyed and executes and delivers an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection therewith and, if the Corporation so elects, provides an appropriate indemnity. No fractional shares of Common Stock shall be issued upon the conversion of Designated Preferred pursuant to this Section B.2(f). In lieu of any fractional shares of Common Stock to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then effective Applicable Conversion Price.

failure of the holder or holders thereof to surrender the certificates for such shares on or prior to such time, all rights with respect to such shares shall immediately cease and terminate at the time of the Special Mandatory Conversion, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor and to receive payment of any dividends declared but unpaid thereon. Such converted Designated Preferred shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Designated Preferred accordingly.

(iv) Definitions. For purposes of this Section B.2(f), the following definitions shall apply:

(A) “2008 Convertible Notes” shall mean those certain promissory notes issued pursuant to the 2008 Note Purchase Agreement (as defined below) at the Initial Closing (as defined in the Note Purchase Agreement), as such promissory notes may be amended from time to time.

(B) “2008 Note Purchase Agreement” shall mean that certain Note Purchase Agreement among the Corporation and the Purchasers named therein, dated on or about September 2, 2008, as such agreement may be amended from time to time.

SECOND: That thereafter, the aforesaid amendment was approved and duly adopted by written consent of the holders of outstanding shares of capital stock having not less than the minimum number of votes that would be necessary to authorize the aforesaid amendment at a meeting at which all shares entitled to vote thereon were present and voted, in accordance with the provisions of Sections 228 and 242 of the General Corporation Law of the State of Delaware and the terms of the Certificate of Incorporation of the Corporation.

[Remainder of Page Intentionally Left Blank]

IN WITNESS WHEREOF, this Certificate of Amendment of Amended and Restated Certificate of Incorporation has been executed by a duly authorized officer of the Corporation on this 2nd day of September 2008.

All Work Product shall be delivered either to Company, or to the client upon request and, in any event, upon any termination or expiration of this Agreement. Employee hereby releases any right, title and interest Employee may have to any Work Product during the term of this Agreement. To the extent the Work Product is not, by operation of law, considered work for hire for the Company, or ownership of all right, title and interest of the intellectual property rights in the Work Product has not otherwise vested exclusively in Company, Employee hereby irrevocably assigns to Company, without further consideration, Employee’s entire right, title, and interest in and to such Work Product.

(b) In this regard, Employee has attached hereto, as Exhibit II, a list describing with particularity all intellectual property, including, but not limited to, property inventions, copyrights, copyright applications or registrations, original works of authorship, developments, improvements, patents, patent applications, trademarks, trademark applications, trade names or trade secrets which were created or owned by Employee prior to the commencement of his employment and which belong solely to Employee or belongs to Employee jointly with another, which relate in any way to any of the Company’s Businesses, products or research and development (collectively referred to as “Prior Inventions”), and which are not assigned to the Company hereunder; or, if no such list is attached, Employee represents that there are no such Prior Inventions. If, in the course of employment, Employee agrees to incorporate into a Company product, process or machine a Prior Invention owned by him or in which he has an interest, absent a prior written agreement or license between himself and the Company for such incorporation of the Prior Invention into a Company product, process or machine, then the Company is hereby granted and shall have a non-exclusive, royalty-free, irrevocable, perpetual, worldwide license (with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell and otherwise distribute such Prior Invention as part of or in connection with such product, process or machine.

(c) Employee agrees to execute documents reasonable or necessary to vest all right, title, and interest in and to any Work Product, including, but not limited to, patents, patent applications and trademark, and copyright filings. Employee shall maintain backup procedures during his/her employment with the Company to ensure that no data, documentation, program, text, specifications, notes, texts, drawings or other information prepared by Employee on behalf of Company or any client are lost or destroyed. If the Company is unable, after reasonable

effort, to secure Employee’s signature on any application for patent, copyright, trademark or other analogous protection or other documents regarding any legal protection relating to Work Product, for any reason whatsoever, Employee hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as his/her agent and attorney-in-fact, to act for and in his/her behalf and stead to execute and file any such application or applications or other documents and to do all other lawfully permitted acts to further the prosecution and issuance of patent, copyright or trademark registrations or any other legal protection thereon with the same legal force and effect as if executed by Employee.

(d) This provision shall not apply to an invention that Employee developed entirely on his or her own time without using the Company’s equipment, supplies, facilities, or trade secret information except for those inventions that either: (i) relate at the time of conception or reduction to practice of the invention to the Company’s business, or actual or demonstrably anticipated research or development of the Company; (ii) result from any work performed by Employee for the Company or any client; or (iii) result from Employee’s use of Company resources or Property.

Remedies:

(a) Employee acknowledges that compliance with Sections 3, 4, 5, 6 and 7 hereof is necessary to protect the business and goodwill of the Company and that any breach of such Sections will irreparably and continually damage the Company in such a manner that money damages will not be an adequate remedy. Consequently, Employee agrees that, in the event of any breach or threatened breach any of the covenants contained in Sections 3 through 7 hereof, the Company shall be entitled to a preliminary and/or permanent injunction in order to prevent the continuation of such damage without having to prove actual damages. The Company may apply for such injunctive relief in any court of competent jurisdiction without the necessity of posting any bond or other security. Nothing contained in this Agreement shall limit the Company’s right to any other remedies at law or in equity.

(b) Employee agrees that if he/she violates any restrictive covenant in this Agreement (including Sections 3, 4 and 5) after his/her employment with the Company has terminated, the term of any such covenant shall be tolled during the period of any such violation.

9. Waiver of Rights: If, in one or more instances, either party shall fail to insist that the other party perform any of the terms of this Agreement, such failure shall not be construed as a waiver by such party of any past, present or future right granted under this Agreement but the obligations of both parties under this Agreement shall continue in full force and effect. This Agreement may not be modified except by an instrument in writing signed by the parties hereto.

10. Applicability and Assignability: The Company shall have the right to assign this Agreement, or any rights and obligations hereunder to its successors and assigns, and all covenants and agreements hereunder shall inure to the benefit of and be enforceable by said successors or assigns. Employee may not assign this Agreement or any rights or obligations hereunder without the prior written consent of Company.

11. Indemnification: Employee, and Employee’s successors, assigns, executors, administrators and personal representatives, shall defend, indemnify and hold the Company harmless from and against any and all liabilities, losses, damages, claims or demands whatsoever (including expenses, court costs and reasonable attorneys’ fees) asserted against or incurred by the Company as a result of or by reason of (a) the damage, destruction or theft of property, (b) the death or injury of Employee or third persons, (c) Company having to defend any claim arising from Employee’s use of proprietary or trade secret information of a prior employer, and from any damages resulting from a final judgment or reasonable settlement of such claims, or (d) any negligence or intentional or willful act or omission of Employee, including errors and omissions arising out of, through or during the performance of Employee’s duties under this Agreement. This indemnification shall include, but not be limited to, claims for infringement of patents, trademarks or copyrights, misappropriation of trade secrets or Confidential Information, and/or breach of any restrictive covenants set forth herein, and is without prejudice to any of Company’s other rights or remedies at law.

12. Reimbursement: Employee hereby authorizes the Company at any time during or after the term of his/her employment to withhold from any amounts otherwise owed to Employee (including, but not limited to, salary, bonus, commissions and expense reimbursements) to the fullest extent permitted by applicable law: any and all amounts due to the Company from Employee, including, but not limited to, cash advances, draws, travel advances, overpayments made by the Company to Employee, amounts received by Employee due to the Company’s error, unpaid personal credit card or phone charges or any other debt Employee owes to the Company for any reason, including amounts with respect to misuse or misappropriation of Company assets or breach of this Agreement.

13.	Survival: Sections 3-12, 14, 15 and 17 hereof shall survive any termination or expiration of this Agreement.

14. Severability: If any of the provisions of this Agreement shall be invalid or unenforceable, such invalidity or unenforceability shall not invalidate or render unenforceable the remainder of this Agreement, but rather the remainder of this Agreement shall be construed as if not containing the particular invalid or unenforceable provision or provisions, and the rights and obligations of the parties shall be enforced accordingly. Moreover, if one or more of the provisions contained in this Agreement shall for any reason be held to be excessively broad as to scope, activity, subject or otherwise so as to be unenforceable at law, such provision or provisions shall be construed by the appropriate judicial body by limiting, revising or reducing it or them, so as to be enforceable to the maximum extent compatible with the applicable law as it shall then appear. Employee hereby further agrees that the language of all parts of this Agreement shall in all cases be construed as a whole according to its fair meaning and not strictly for or against any of the parties.

15. Choice of Law: The construction, interpretation and performance of this Agreement shall be governed and construed in accordance with the laws of the state of New Jersey, without giving effect to New Jersey’s principles of conflicts of laws. Any claims or legal actions by one party against the other shall be commenced and maintained in any state or federal court located in New Jersey, and Employee hereby submits to the jurisdiction and venue of any such court.

16. Headings: The various headings in the Agreement are inserted for convenience only and shall have no effect on the interpretation of this Agreement or any part hereof.

17. Entire Agreement: This Agreement constitutes the entire Agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior understandings and agreements between the parties hereto relating to the subject matter hereof. Employee acknowledges that Employee is not entering into this Agreement in reliance upon any statement or representation except as otherwise expressly set forth herein.

IN WITNESS WHEREOF, this Agreement has been duly executed and delivered by the parties as of date first above written.

Opinion of ▇▇▇▇▇▇▇ Procter LLP

[▇▇▇▇▇▇▇ Procter LLP Letterhead]

September 2, 2008

To: The Purchasers Listed on the Schedule of Purchasers to the Purchase Agreement referred to below at the Initial Closing

Ladies and Gentlemen:

We have acted as counsel to Aegerion Pharmaceuticals, Inc., a Delaware corporation (the “Company”), in connection with the sale to you today of a series of Senior Subordinated Convertible Promissory Notes of like tenor pursuant to that certain Note Purchase Agreement, dated as of September 2, 2008, by and among the Company and the Purchasers named therein (the “Purchase Agreement”). We are furnishing this opinion letter to you pursuant to Section 5(d) of the Purchase Agreement. Capitalized terms that are defined in the Purchase Agreement and not otherwise defined in this opinion letter are used in this opinion letter as so defined.

The Purchase Agreement and the Notes being delivered by the Company under the Purchase Agreement are referred to collectively in this opinion letter as the “Transaction Documents.”

We have reviewed such documents and made such examination of law as we have deemed appropriate to give the opinions expressed below. We have relied, without independent verification, on certificates of public officials and, as to matters of fact material to the opinions set forth below, on representations in the Purchase Agreement and certificates of officers of the Company.

Our opinions regarding valid existence and good standing in numbered paragraph 1 are based solely on certificates of the Delaware Secretary of State and, in the case of valid existence, a review of the Company’s certificate of incorporation and an officer’s certificate confirming that the Company has taken no action looking to its dissolution. Our opinions in numbered paragraph 1 below regarding the due qualification and good standing of the Company as a foreign corporation are based solely on certificates of the Secretaries of State or other appropriate officials of the respective jurisdictions identified on Schedule A to this opinion letter in which the Company is qualified as a foreign corporation.

Our opinions set forth below are limited to the Delaware General Corporation Law and the federal law of the United States. Our opinions set forth below do not address securities laws. We note that the Transaction Documents provide that they are to be governed by New Jersey law. The opinions in numbered paragraph 3 regarding the validity, binding effect and enforceability of the Transaction Documents are given as though each of the Transaction Documents were governed by the internal law of Massachusetts.

Based upon the foregoing and subject to the additional qualifications set forth below, we are of the opinion that:

The Company is validly existing as a corporation in good standing under Delaware law and is qualified as a foreign corporation and in good standing in the jurisdictions set forth on Schedule A hereto.

The Company has the corporate power to execute and deliver each of the Transaction Documents and perform its obligations thereunder.

Each of the Transaction Documents has been duly authorized, executed and delivered by the Company and constitutes its valid and binding obligation enforceable against it in accordance with its terms.

The execution and delivery by the Company of the Transaction Documents and the performance by the Company of its obligations under the Transaction Documents, including (i) its sale and issuance of the Notes; and (ii) its issuance of Common Stock issuable to a Defaulting Purchaser pursuant to the terms of Section 2(d) of the Purchase Agreement (the “Pay-to-Play Conversion Shares”), do not and will not (a) violate the Delaware General Corporation Law or any federal statute, rule or regulation, (b) result in a breach of, or constitute a default under, any of the agreements or instruments listed in Schedule B to this opinion letter, or (iv) violate the Company’s certificate of incorporation or by-laws.

No consent, approval, license or exemption by, order or authorization of, or filing, recording or registration with any Delaware governmental authority pursuant to the Delaware General Corporation Law or any federal governmental authority is required to be obtained or made by the Company in connection with its execution and delivery of the Transaction Documents to which it is a party or the performance by it of its obligations thereunder, including (i) its sale and issuance of the Notes; and (ii) its issuance of Pay-to-Play Conversion Shares pursuant to the terms of Section 2(d) of the Purchase Agreement, other than those that have been obtained or made.

We are not representing the Company in any pending litigation in which it is a named defendant that challenges the validity or enforceability of, or seeks to enjoin the performance of, the Transaction Documents.

Our opinions above are subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general application affecting the rights and remedies of creditors and to general principles of equity.

We note that some of the Purchasers and affiliates of some of the Purchasers are directors or officers of the Company; we express no opinion as to compliance with fiduciary duties or legal requirements applicable to transactions in which directors or officers have an interest or legal doctrines applicable to fairness of directors’ conduct to each other. We also express no opinion as to the validity, binding effect and enforceability of (a) provisions in the Transaction Documents relating to the choice of forum for resolving disputes or (b) the indemnification obligations of the Company in the Purchase Agreement.

This opinion letter and the opinions it contains shall be interpreted in accordance with the Legal Opinion Principles issued by the Committee on Legal Opinions of the American Bar Association’s Business Law Section as published in 53 Business Lawyer 831 (May 1998).

This opinion letter is being furnished only to you for your use solely in connection with the Purchase Agreement and the transactions contemplated thereby, and neither it nor the opinions it contains may be relied on for any other purpose or by anyone else.

Very truly yours,

/s/ ▇▇▇▇▇▇▇ Procter
