In the case of registration, qualification, exemption or compliance effected by Amicus pursuant to the Transaction Documents, Amicus will, upon request of any Purchaser, inform such Purchaser as to the status of such registration, qualification, exemption and compliance. Amicus shall, at its expense and in addition to its obligations under Section 7.1, as expeditiously as reasonably possible:

(a) use its commercially reasonable efforts to keep such registration, and any required qualification, exemption or compliance under state securities laws, continuously effective with respect to the Purchasers and its permitted assignees, until the date all Shares and Warrant Shares registered by such Registration Statement shall have been sold or may be sold pursuant to Rule 144 without regard to volume limitations. The period of time during which Amicus is required hereunder to keep the Registration Statement effective is referred to herein as the “Registration Period.”

(b) advise Purchasers promptly (and, in any event, within five business days):

(i) when the Registration Statement or any amendment thereto has been filed with the SEC and when the Registration Statement or any post-effective amendment thereto has become effective;

(ii) of the receipt by Amicus of any notification from the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for such purpose;

(iii) of the receipt by Amicus of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(iv) of the occurrence of any event that requires the making of any changes in the Registration Statement or the prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in the light of the circumstances under which they were made) not misleading;

(c) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(d) if any Purchaser so requests in writing, promptly furnish to such Purchaser, without charge, at least one copy of such Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if explicitly requested, all exhibits in the form filed with the SEC;

(e) during the Registration Period, promptly deliver to each Purchaser, without charge, at least one copy of the prospectus included in such Registration Statement and any amendment or supplement thereto and as many additional copies as each Purchaser may reasonably request; and Amicus consents to the use, consistent with the provisions hereof, of the prospectus or

any amendment or supplement thereto by each Purchaser in connection with the offering and sale of the Registrable Securities covered by the prospectus or any amendment or supplement thereto;

(f) during the Registration Period, if a Purchaser so requests in writing, deliver to such Purchaser, without charge, (i) one copy of the following documents, other than those documents available via XXXXX (and excluding, in each case, exhibits thereto): (A) its annual report to its stockholders, if any (which annual report will contain financial statements audited in accordance with GAAP by a firm of certified public accountants of recognized standing), (B) if not included in substance in its annual report to stockholders, its annual report on Form 10-K (or similar form), (C) its definitive proxy statement with respect to its annual meeting of stockholders, (D) each of its quarterly reports to its stockholders, and, if not included in substance in its quarterly reports to stockholders, its quarterly report on Form 10-Q (or similar form), and (E) a copy of the Registration Statement; and (ii) if explicitly requested, any exhibits filed with respect to the foregoing;

(g) upon the occurrence of any event contemplated by Section 7.3(b)(iv), Amicus will use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to the Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to the Purchasers, the prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(h) comply in all material respects with all applicable rules and regulations of the SEC which could affect the sale of the Registrable Securities;

(i) use its commercially reasonable efforts to cause all Registrable Securities to be listed on each securities exchange or market, if any, on which equity securities issued by Amicus have been listed;

(j) use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities contemplated hereby and to enable the Purchasers to sell Registrable Securities under Rule 144; and

(k) permit counsel for the Purchasers to review the Registration Statement and all amendments and supplements thereto, within two business days prior to the filing thereof with the SEC;

provided that, in the case of clause (k) above, Amicus will not be required to delay the filing of the Registration Statement or any amendment or supplement thereto to incorporate any comments to the Registration Statement or any amendment or supplement thereto by or on behalf of any Purchaser if such comments would require a delay in the filing of such Registration Statement, amendment or supplement, as the case may be.

7.4 Furnishing Information.

(a) It shall be a condition precedent to the obligations of Amicus to take any action pursuant to Section 7.1 that the selling Holders shall furnish to Amicus such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be legally required under the Securities Act or otherwise required by the SEC to effect the registration of their Registrable Securities.

7.5 Indemnification; Contribution.

(a) Amicus shall indemnify and hold harmless each Holder (including the employees, agents, representatives, officers and directors of each Purchaser and its Affiliates) (each a “Purchaser Indemnitee”) from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue, or allegedly untrue, statement of a material fact contained in any Registration Statement, prospectus or preliminary prospectus or notification or offering circular prepared by Amicus in connection with the registration and/or offering of the Registrable Securities (as amended or supplemented if Amicus shall have furnished any amendments or supplements thereto) or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information concerning such Holder furnished in writing to Amicus by such Holder specifically and expressly for inclusion in such document.

(b) Each Holder shall indemnify and hold harmless Amicus, and its respective directors, officers, employees and each Person who controls Amicus (within the meaning of the Securities Act and the Exchange Act) from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue, or allegedly untrue, statement of a material fact contained in any Registration Statement, prospectus or preliminary prospectus or notification or offering circular prepared by Amicus in connection with the registration and/or offering of the Registrable Securities (as amended or supplemented if Amicus shall have furnished any amendments or supplements thereto) or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, if such statement or omission was made in reliance upon and in conformity with any information concerning such Holder furnished in writing to Amicus by such Holder specifically and expressly for use in the preparation of such document.

(c) Each Person entitled to indemnification hereunder (the “Indemnified Party”) agrees to give prompt written notice to the indemnifying party (the “Indemnifying Party”) after the receipt by the Indemnified Party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to the Transaction Documents; provided, however, that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party hereunder unless, and only to the extent that, such failure results in the Indemnifying Party’s forfeiture of substantive rights or defenses. If notice of commencement of any such action is given to the Indemnifying Party as above provided, the Indemnifying Party shall be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense,

with counsel chosen by it and reasonably satisfactory to such Indemnified Party. The Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be paid by the Indemnified Party unless (i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party fails to assume the defense of such action with counsel reasonably satisfactory to the Indemnified Party in its reasonable judgment or (iii) the named parties to any such action (including any impleaded parties) have been advised by such counsel that either (x) representation of such Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct or (y) there may be one or more legal defenses available to it which are different from or additional to those available to the Indemnifying Party. In either of such cases, the Indemnifying Party shall not have the right to assume the defense of such action on behalf of such Indemnified Party. No Indemnifying Party shall be liable for any settlement entered into without its written consent (other than in the case where the Indemnifying Party is unconditionally released from liability and its rights are not adversely effected), which consent shall not be unreasonably withheld.

(d) If the indemnification provided for in this Section 7.5 from the Indemnifying Party pursuant to applicable law is unavailable to an Indemnified Party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative faults of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, Knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Sections 7.5(a), (b) and (c), any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7.5(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of an intentional or fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person.

7.6 Rule 144 Reporting. In order to make the benefits of the rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration available to the Holders, Amicus agrees to use commercially reasonable efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144(c)(1) or any similar or analogous rule promulgated under the Securities Act, at all times after the SPA Effective Date;

(b) file with the SEC, in a timely manner, all reports and other documents required of Amicus under the Exchange Act; and

(c) so long as any Holder owns any Registrable Securities, furnish such Holders forthwith upon request: (i) a written statement by Amicus as to its compliance with the reporting requirements of Rule 144 under the Securities Act, and of the Exchange Act; (ii) a copy of the most recent annual or quarterly report of Amicus; and (iii) such other reports and documents as a Holder may reasonably request in availing itself of any rule of regulation of the SEC allowing it to sell any such securities without registration.

7.7 Assignment of Registration Rights. The rights and obligations under this Section 7 may only be assigned by a Holder to a transferee or assignee of Registrable Securities that is (a) an Affiliate or (b) a successor (by operation of law or otherwise) to substantially all the business or assets of such Holder; provided, however, that such attempted assignment shall be void unless (i) such Holder, within 30 days after such transfer, furnishes to Amicus written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned, and (ii) such transferee agrees to be subject to all obligations and restrictions with respect to the Registrable Securities set forth in this Agreement.

8. Stock Ownership Governance.

8.1 Lock-Up Period. Excluding any transfers or intra-company disposal of the Securities between a Purchaser and any of its Affiliates, during the period beginning on the Closing Date and ending on the earlier of (a) the day after the date that is six months after the Closing Date and (b) the date such Registration Statement filed pursuant to Section 7.1 becomes effective (the “Lock-Up Period”), each Purchaser shall not, and shall cause any other Holder not to, without the prior written consent of Amicus, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Securities or enter into a transaction which would have the same effect.

8.2 Market Stand-Off Agreement. During the Lock-Up Period, each Purchaser agrees that in connection with any registration of Amicus’ securities that, upon the request of Amicus or the underwriters managing any underwritten offering of Amicus’ securities, not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registrable Securities without the prior written consent of Amicus or such underwriters, as the case may be, for such period of time from the effective date of such registration as Amicus or the underwriters may specify, provided that each executive officer and director of Amicus agrees to a similar lockup.

8.3 Remedies. Without prejudice to the rights and remedies otherwise available to the parties, Amicus shall be entitled to equitable relief by way of injunction if any Purchaser or any other Holder breaches or threatens to breach any of the provisions of this Section 8.

9. Covenants.

9.1 Covenant of Amicus.

(a) Amicus hereby covenants and agrees that it shall take all necessary and appropriate actions to ensure that it shall have available under its certificate of incorporation as in

effect on the Closing Date sufficient authorized but unissued shares of its Common Stock to issue and sell to Purchasers all of the Shares.

(b) Amicus will file with Nasdaq all documentation required by Nasdaq, if any, in connection with the issuance of the Shares and Units.

10. Miscellaneous.

10.1 Termination. This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect whatsoever on the obligations between Amicus and the other Purchasers, by written notice to the other parties, if the Closing has not been consummated on or before December 20, 2013; provided, however, that no such termination will affect the right of any Party to xxx for any breach by the other Party (or Parties). In the event of termination of this Agreement by the Purchasers, this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of the Purchasers or Amicus, other than the provisions of this Section 10.1, and except to the extent that such termination results from a material breach by a party of its representations, warranties, covenants or agreements set forth in this Agreement.

10.2 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of Delaware, without regard to the principles of conflicts of law thereof. Each Party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such Party at the address in effect for notices to it under the Transaction Documents and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law.

10.3 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by the Parties and delivered to the other Parties, it being understood that the Parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

10.4 Public Statements. Any statement to the public regarding this the Transaction Documents shall be approved in advance by Amicus and the Purchasers, except as otherwise required by law, rule, regulation, legal process or applicable SEC Guidance.

10.5 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their successors and permitted assigns. Amicus may not assign this Agreement or any rights or obligations hereunder without the prior written consent of Purchasers purchasing at least 85% of the Securities issuable hereunder. Subject to Section 7.7, any Purchaser

may assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Securities, provided such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”

10.6 Entire Agreement. The Transaction Documents, together with the exhibits and schedules hereto, contain the entire understanding of the Parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such matters (other than confidentiality agreements to which Amicus is a party to with the Purchasers), which the Parties acknowledge have been merged into such documents, exhibits and schedules.

10.7 Separability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the Parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the Parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

10.8 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and Amicus does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to Amicus, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

10.9 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, Amicus shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to Amicus of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances may also be required to pay a customary bond and any reasonable third-party costs associated with the issuance of such replacement Securities.

10.10 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and Amicus will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agrees to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

10.11 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in their review and negotiation of the Transaction Documents.

10.12 Amendment and Waiver. No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by Amicus and Purchasers purchasing at least 85% of the Securities issuable hereunder or, in the case of a waiver, by the Party against whom enforcement of any such waived provision is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

10.13 Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number set forth on the signature pages attached hereto prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number set forth on the signature pages attached hereto on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (c) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature pages attached hereto.

10.14 Fees and Expenses. Amicus shall pay up to $15,000 of fees and expenses actually incurred by Redmile Group, LLC in connection with the Offering. Except as expressly set forth in the Transaction Documents to the contrary, each Party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. Amicus shall pay all transfer agent fees, stamp taxes and other taxes and duties levied in connection with the delivery of any Securities to the Purchasers.

10.15 Titles and Subtitles. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.

10.16 Counterparts; Effectiveness. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one instrument. This Agreement shall become effective when each Party hereto shall have received counterparts thereof signed and delivered (by telecopy or other electronic means) by the other Parties hereto.

10.17 Construction. The Parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments hereto.

10.18 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the Parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 7.5.

This Securities Purchase Agreement is hereby executed as of the date first above written.
