    Re:       Consent to Disclosure

     

    Dear Friedrich:

     

    Amylin Pharmaceuticals, Inc. (“Amylin”)
      has out-licensed its lipodystrophy program in certain countries and is presently contemplating the negotiation of additional licenses of its lipodystrophy program in other countries (collectively, such existing license and contemplated licenses are
      hereinafter referred to as the “Lipodystrophy Transaction”).

     

    In connection with the Lipodystrophy Transaction, Amylin would like to share with existing and potential licensees/partners
      the existence of its relationship with Sandoz GmbH (“Sandoz”), including the existence and terms of the Process Transfer and Initial Manufacturing
      Agreement, dated November 1, 2006, as amended, the Contract Manufacturing Agreement, dated September 30, 2010, as amended, and the Quality Agreement dated March 13, 2007, as amended, each by and between Amylin and Sandoz (each an “Agreement” and collectively, the “Agreements”), certain Confidential Information (as defined in each Agreement) and all documents and agreements related thereto (collectively, the “Disclosure”). Amylin would also like to make the Disclosure to existing and new licensees/partners to support such parties’ filings of regulatory documents, and communications related thereto, with
      applicable regulatory authorities. It is understood that Amylin will promptly provide Sandoz with the names of the existing and potential licensees/partners to which the Disclosure and/or the Agreements will be disclosed.

     

    The parties acknowledge that this Consent to Disclosure is not intended nor shall it be construed to amend the Agreements
      with respect to the specific regulatory or statutory requirements pursuant to which Sandoz has agreed to manufacture and/or release products. The parties further acknowledge that the compliance with the regulatory and statutory requirements of
      countries/jurisdictions in addition to those set forth in the Agreements will be evaluated by Sandoz and Amylin on a case-by-case basis and the relevant terms and conditions (including, but not limited to, the relevant financial provisions)
      will be subject to good faith negotiations.

     

    In light of the above, Amylin hereby requests Sandoz’s consent to the Disclosure in connection with the Lipodystrophy Transaction and
      also for the purpose of permitting Amylin’s licensees/partners to disclose and use information obtained pursuant to the Disclosure to the extent necessary for regulatory documents and/or communications with regulatory authorities for the development
      and/or commercialization of lipodystrophy products. The Disclosure will be pursuant to confidentiality agreements between Amylin and its existing and potential licensees/partners, which will include obligations of confidentiality consistent with
      those of the

    
      
        
 

    

    CONFIDENTIAL

    Agreements. Such confidential disclosure agreements with potential partners shall include restrictions on further disclosure of Sandoz
      Confidential Information by such potential partners. It is however understood that any such potential partners will have the right to disclose information on the Lipodystrophy Transaction to their respective agents, advisors, or representatives who
      need to know such information for purposes of assisting or advising such potential partners with respect to the Lipodystrophy Transaction.

     

    Please execute this consent and return a copy of the executed consent as soon as possible to [***] via e-mail at [***]. By signing
      below, you hereby confirm your grant of the requested consent. You should retain a duplicate copy of this letter for your records. Should you have any questions with respect to the foregoing, please call [***] at [***]. Your prompt attention to this
