9.1 Amylin shall defend, indemnify and hold Bachem and its Affiliates and their respective employees, directors, officers, shareholders and agents (each, an “Amylin Indemnitee”) harmless against any liability, judgment, demand, action, suit, loss, damage, cost and other expense (including reasonable attorney’s fees) (“Liability”) incurred by such Amylin Indemnitee resulting from any third party claims made or proceedings brought against Bachem or other

12

Amylin Indemnitee to the extent such Liability arises from (i) Amylin’s negligence or willful act or omission in the possession, use, importation, marketing or sale of Product, (ii) Amylin’s material breach of this Agreement, (iii) Amylin’s breach of any representation or warranty set forth in Article 8, or (iv) any repackaging or use by or on behalf of Amylin of Product after delivery to Amylin by Bachem hereunder, in each case, except to the extent Bachem is obligated to indemnify any Amylin Indemnitee for such claim or proceeding under Section 9.2 below.

9.2 Bachem shall defend, indemnify and hold Amylin and its Affiliates and their respective employees, directors, officers, shareholders and agents harmless against any Liability incurred by any of them resulting from any third party claims made or proceeding brought against Amylin or any such indemnitee to the extent that such Liability arises from (i) Bachem’s negligence or willful act or omission in the manufacture, storage or delivery of Product; (ii) Bachem’s material breach of this Agreement; or (iii) Bachem’s breach of any representation or warranty set forth in Article 8.

Each indemnified party agrees to give the indemnifying party prompt written notice of any matter upon which such indemnified party intends to base a claim for indemnification (an “Indemnity Claim”) under Article 9. The indemnifying party shall have the right to participate jointly with the indemnified party in the indemnified party’s defense, settlement or other disposition of any Indemnity Claim. With respect to any Indemnity Claim relating solely to the payment of money damages and which could not result in the indemnified party’s becoming subject to injunctive or other equitable relief or otherwise adversely affect the business of the indemnified party in any manner, and as to which the indemnifying party shall have acknowledged in writing the obligation to indemnify the indemnified party hereunder, the indemnifying party shall have the sole right to defend, settle or otherwise dispose of such Indemnity Claim, on such terms as the indemnifying party, in its sole discretion, shall deem appropriate, provided that the indemnifying party shall provide reasonable evidence of its ability to pay any damages claimed and with respect to any such settlement shall have obtained the written release of the indemnified party from the Indemnity Claim. The indemnifying party shall obtain the written consent of the indemnified party, which shall not be unreasonably withheld, prior to ceasing to defend, settling or otherwise disposing of any Indemnity Claim if as a result thereof the indemnified party would become subject to injunctive or other equitable relief or the business of the indemnified party would be adversely affected in any manner.

9.3  Each party shall at all times comply, through insurance, with all statutory workers’ compensation and employers’ liability requirements covering any and all employees with respect to activities performed under this Agreement.  In addition to the foregoing, each party shall obtain and maintain, occurrence-based or claims made Broad Form Comprehensive General Liability (“BFCGL”) Insurance with a reputable and financially secure insurance carrier(s) having at least an Excellent rating (A- rating or above by A.M.

10.                               Confidential Information

Confidential Information will be as defined by and treated in accordance with the Confidential Disclosure Agreement dated February 15, 2002 between Amylin and Bachem, a copy of which is attached hereto as Exhibit 2, which shall remain in full force and effect in accordance with its terms.  The parties, however, agree that the following shall apply to Confidential Information disclosed under this Agreement:  (A) each party shall use the other party’s Confidential Information solely for the purposes contemplated under this Agreement, (B) the non-disclosure and confidentiality obligations shall remain in effect during the term of this Agreement and for a period of five (5) years thereafter, and (C) Amylin shall have the right to disclose Bachem’s Confidential Information, without Bachem prior consent, to Regulatory Authorities in accordance with Article 3.

11.                               Force Majeure

If the performance by either party of any obligation under this Agreement, other than the payment of money, is prevented or impaired by Force Majeure for any cause beyond the reasonable control of the defaulting party, such party shall be excused from performance so long as such situation continues to prevent or impair performance, provided the party claiming such excuse shall have promptly notified the other party of the existence, nature, duration and other details of such cause and shall at all times use its reasonable efforts consistent with its normal business practices to resume a complete performance. If either party anticipates that a Force Majeure may occur, that party shall notify the other immediately and explain the nature, details and expected duration thereof.

The affected party will advise the other from time to time as to the progress in remedying the situation and as to the time when the affected party expects to resume its obligations and shall notify the other as to the expiration of any Force Majeure as soon as the affected party knows the date thereof.

“Force Majeure” shall mean fire, flood, sabotage, shipwreck, embargo, explosion, accident, riot, act of governmental authority (including, without limitation, acts relating to raw material or product allocation), acts of God, acts of war, and acts of terrorism and similar events beyond the reasonable control of the applicable party.

In the event of a Force Majeure affecting Bachem, Bachem may prorate and allocate manufacturing capacity among its Affiliates, Amylin and Bachem’s other customers, in proportion to purchases of products by such Affiliates, Amylin and other customers during the 12-month period preceding such Force Majeure event.

Notwithstanding the occurrence of a Force Majeure event, if Bachem shall be unable to supply Products in such quantities as Amylin shall request and in compliance with the delivery periods set forth in this Agreement, Amylin shall be permitted (with no obligation to Bachem) to exercise its rights under Section 7.4 and have another source manufacture Product on Amylin’s behalf using the process described in the master batch records for the Product, and Amylin shall thereafter have no obligation to purchase Products from Bachem until any contractual obligations that Amylin has assumed in connection with obtaining a substitute supply of Products shall have terminated. Amylin shall have no obligation to affirmatively terminate any such contractual

14

arrangements.

C O N F I D E N T I A L

CONFIDENTIAL DISCLOSURE AGREEMENT

THIS AGREEMENT is entered into as of February 15, 2002 by and between AMYLIN PHARMACEUTICALS, INC., a Delaware corporation (“AMYLIN”), having a place of business at 9373 Towne Centre Drive, Suite 250, San Diego, California 92121, and BACHEM, INC., a California corporation (“RECIPIENT”), with offices at 3132 Kashiwa Street, Torrance, California.

RECITALS

WHEREAS AMYLIN owns or is in possession of certain proprietary information relating to its products and research efforts, including therapy for and diagnosis of Type I and Type II diabetes mellitus, obesity and dyslipidemia and other metabolic and cardiovascular disorders, and compounds, procedures and processes related thereto (collectively, the “Products and Research”); and

WHEREAS RECIPIENT desires to be made aware of, and AMYLIN is willing to disclose on a confidential basis, certain information relating to the Products and Research solely to allow RECIPIENT to evaluate one or more mutual business relationships (each an “Evaluation”) which the parties have agreed to discuss; and

NOW, THEREFORE, in consideration of the foregoing, and of the mutual covenants, terms and conditions hereinafter expressed, RECIPIENT and AMYLIN agree as follows:

AGREEMENT

1.             “Confidential Information” shall mean information whether written or oral, relating to the Products and Research, financial, business and other information of AMYLIN, including patent disclosures, patent applications, structures, models, techniques, trade secrets, know-how, processes, compositions, compounds, apparatuses, projections, customer information, and business and marketing plans disclosed by AMYLIN or its agents, to RECIPIENT or obtained by RECIPIENT through observation or examination, but only to the extent that such foregoing information is identified or marked as “confidential”.

2.             RECIPIENT agrees the Confidential Information is proprietary information of AMYLIN and that for a period of five (5) years from the date of disclosure, RECIPIENT will not disclose any of the Confidential Information to any third parties, without the written consent of AMYLIN (except in accordance with the terms of Section 4 or Section 6 below).  RECIPIENT agrees not to use any of the Confidential Information at any time except for the purposes of an Evaluation and not to make any chemical analysis of any material without the written consent of AMYLIN.

3.             The obligations of confidentiality and non-use shall not apply to information which, as established by written records:

a.             is publicly known prior to disclosure or has become publicly known, without fault on the part of RECIPIENT, subsequent to disclosure hereunder; or

b.             is otherwise known by RECIPIENT prior to disclosure hereunder or is generated for RECIPIENT by persons who have not had access to or knowledge of the Confidential Information;  or

21

c.             is hereafter received by RECIPIENT at any time from a source other than AMYLIN or its agents, lawfully having possession of such information and under no obligation of confidentiality with respect to such information.

4.             RECIPIENT agrees that any disclosure of the Confidential Information will only be to employees or agents of RECIPIENT on a need to know basis; provided that (i) such employees and agents are bound by written agreements to maintain in confidence and not use the Confidential Information under terms at least as restrictive as the terms of this Agreement, and (ii) RECIPIENT will remain liable for any breach by its employees or agents of any obligations hereunder.  RECIPIENT further agrees, upon request, to identify to AMYLIN those persons to whom the Confidential Information was disclosed.  Confidential Information disclosed prior to the date of this Agreement for purposes of an Evaluation shall be deemed to fall within the scope of this Agreement.

5.             RECIPIENT agrees to promptly return to AMYLIN all tangible items relating to the Confidential Information, including all written materials, photographs, models, or samples and the like and all copies thereof, upon completion of an Evaluation (except for a single archive copy which may be retained for the sole purpose of determining the scope of the obligations under this Agreement).

6.             In the event that RECIPIENT is required by law, regulation, or court order to disclose any Confidential Information, RECIPIENT agrees to  promptly notify AMYLIN of such demand prior to such disclosure and to give AMYLIN a reasonable opportunity to contest such disclosure.  Such disclosed information shall remain Confidential Information.

7.             This Agreement may not be assigned by RECIPIENT and shall not be construed to grant any license or other rights to the Confidential Information to RECIPIENT.

8.             RECIPIENT’s evaluation of the Confidential Information shall be at its own risk and RECIPIENT agrees to hold harmless and to indemnify AMYLIN against any and all claims, judgments, costs, awards, expenses (including reasonable attorneys’ fees), and liabilities of every kind arising from any use of the Confidential Information by RECIPIENT.

9.             RECIPIENT shall not disclose the name of AMYLIN, the existence of this Agreement, or the subject matter hereof in any publicity, advertising, or public announcement without AMYLIN’s written consent.

10.           This Agreement sets forth the entire agreement between AMYLIN and RECIPIENT, and fully supersedes any and all prior and contemporaneous agreements or understandings pertaining to the subject matter hereof.  No modification to this Agreement shall be effective unless in writing and signed by both parties.

11.           The failure of AMYLIN to insist upon strict performance of any provision of this Agreement or to exercise any right hereunder shall not constitute a waiver of that provision or right under this Agreement or of any other provision or right under this Agreement.  If any provision of this Agreement is declared invalid, illegal or unenforceable, such provision shall be severed and all remaining provisions shall continue in full force and effect.

12.           This Agreement shall be construed and enforced in accordance with the laws of the State of California (except its choice of law rules), and RECIPIENT hereby submits to the jurisdiction and venue of the California courts, both state and federal.  RECIPIENT acknowledges that improper disclosure could cause irreparable harm to AMYLIN and agrees that AMYLIN may seek injunctive relief to enforce this Agreement.

13.           This Agreement shall be effective as of the date first written above, and shall remain in full force and effect until terminated by either party on thirty (30) days written notice; provided that the terms of this Agreement shall remain in effect with respect to any Confidential Information disclosed prior to such termination date.

22

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed by their duly authorized representatives as of the day and year above written.
