 2.4     For each gram of Product supplied hereunder
by LONZA, AMYLIN will pay to LONZA a price [...***...] based on the cumulative volume of Product ordered for delivery during any given Contract Year. The [...***...] price to be billed to AMYLIN for any Lot or other discrete

 2.5     In the event the amount of Product delivered by LONZA pursuant to any purchase
order is less than the amount of Product ordered by such purchase order, LONZA will use its best commercial efforts to supply the amount of Product ordered but not delivered as soon as is feasible. In the event the amount of Product manufactured by

 2.6     If, with respect to any given Contract Year, the annual
volume assumptions on which the Product Prices reflected in any one or more invoices for Product shipped to AMYLIN during such Contract Year are based are incorrect, then within [...***...] after the end of such Contract Year, LONZA will send
corrected invoices to AMYLIN indicating the actual per gram price for Product shipped during such Contract Year with respect to such invoices based on the actual volume of Product ordered for delivery during such Contract Year. If, on the basis of
all such corrected invoices with respect to a particular Contract Year, when considered in the aggregate, the amount paid or payable by AMYLIN for Product shipped during such Contract Year against invoices previously issued by LONZA is in excess of
the amount payable by AMYLIN pursuant to all such corrected invoices then LONZA shall, contemporaneous with the delivery of such corrected invoices and at AMYLIN’s option, give AMYLIN a full refund of the excess amount or, with respect to any
previously issued but as yet unpaid invoice, issue an appropriate credit equal to the excess amount of any such invoice. If, on the basis of all such corrected invoices with respect to a particular Contract Year, when considered in the aggregate,
the amount paid or payable by AMYLIN for Product shipped during such Contract Year against invoices previously issued by LONZA is less than the amount payable by AMYLIN pursuant to all such corrected invoices, then AMYLIN shall, within

 2.7     AMYLIN shall have the right (through any
independent agents or representatives that are reasonably acceptable to LONZA and upon reasonable advance notice to LONZA), with respect to any Contract Year ending not more than thirteen [...***...] prior to the date of notice
requesting an audit, to audit the books and records of LONZA to determine whether or not the amounts reflected on any original invoices relevant to any such Contract Year or any corrected invoices issued by LONZA to AMYLIN in accordance with
Paragraph 2.5 set forth immediately above are accurate. In the event that, as a consequence of any such audit or examination, AMYLIN reasonably disagrees with any amounts set forth on original or corrected invoices issued by LONZA, AMYLIN shall
inform LONZA in writing and in reasonable detail of the amounts to be refunded and, unless and to the extent LONZA disputes the amounts set forth by AMYLIN in any such notice, LONZA will refund to AMYLIN any such undisputed amounts within
[...***...] of the receipt of any such notice from AMYLIN. In the event LONZA does dispute all or any portion of any refund claimed by AMYLIN, LONZA will so notify AMYLIN within such [...***...] period and the parties will attempt
thereafter to resolve such dispute amicably and, if they cannot do so, may agree to submit the dispute to binding arbitration or independently pursue any other remedies available to them to resolve such dispute. AMYLIN shall bear the expense of such
audit; provided, however, that, if such audit reflects overpayments by AMYLIN, which are undisputed or confirmed as overpayments pursuant to the dispute resolution procedure referred to in the preceding sentence, in excess of [...***...] of
the payments actually due by AMYLIN hereunder for the applicable period, then LONZA shall reimburse AMYLIN for the reasonable expenses of such audit. 
 2.8     LONZA shall invoice AMYLIN with a single invoice equal to [...***...] of the campaign price upon start of the production. Then, LONZA shall invoice AMYLIN with an
additional single invoice for the remaining [...***...] of the campaign price upon LONZA release of the Product by LONZA issuance of a COA in accordance with Section 6. Invoices shall be due within [...***...] of submission by
LONZA. In acknowledgement of the current invoicing process of LONZA, AMYLIN receipt and LONZA submission of the invoice is deemed to occur on the same day. In the event LONZA modifies its invoicing process, LONZA

AMYLIN shall submit to LONZA a rolling forecast of Product that AMYLIN in good faith estimates it will order for delivery from LONZA for the [...***...] (as updated on a rolling basis, a [...***...]). Thereafter, on and as of the

	4.	 Recalls and Similar Actions 

4.1     If there is a recall, withdrawal or field correction with respect to, or any governmental
seizure of, any finished formulated drug product containing the Product (“Recall Action”), which Recall Action is due in part to (i) the failure of Product manufactured by LONZA to meet any of the Product Requirements, or
(ii) the alleged negligent or intentional wrongful act or omission of LONZA in connection with the manufacture of Product, then AMYLIN or, in the case of OUS Sales subject to a Recall Action, Collaboration Partner, will notify LONZA promptly of
the details regarding such Recall Action, including providing copies of all relevant documentation concerning such Recall Action. LONZA will assist AMYLIN and its Collaboration Partner in investigating any such Recall Action, if AMYLIN or its
Collaboration Partner so requests, and all regulatory contacts that are made and all activities concerning such Recall Action will be initiated and coordinated by AMYLIN or, in the case of OUS Sales subject to a Recall Action, Collaboration Partner
with LONZA’s involvement and assistance, as reasonably requested by AMYLIN or its Collaboration Partner.

	5.	 Shipment and Delivery 

 On or before the delivery date of each shipment of Product LONZA shall deliver to AMYLIN the Batch Release Documents for each Lot of Product being shipped. Delivery of the Batch Release Documents
by LONZA to AMYLIN shall mean LONZA has tested and analyzed such Lot of Product to ensure compliance with Product Specifications as defined in Exhibit B and other Product Requirements and, if applicable, Validation Requirements. AMYLIN is
entitled to rely on the LONZA Batch Release Documents for all purposes of this Agreement. LONZA shall be primarily responsible for all such initial testing of Product; provided, however, AMYLIN shall have the right to subsequent inspection and final
acceptance or rejection of such Product pursuant to the terms of this Agreement. LONZA shall prepare Product for shipment and subject to the prior approval of AMYLIN and the terms of the Quality Agreement, arrange for shipment of Product to the
location specified by AMYLIN in its Purchase Order for such Lot. Shipment terms are F.C.A. LONZA’s Facility (Incoterms 2000). All shipments must be accompanied by a packing slip which describes the articles, states the purchase order number and
shows the shipment’s designation. LONZA agrees to promptly forward the original bill of lading or other shipping receipt for each shipment in accordance with AMYLIN’s instructions. In accordance with AMYLIN’s written instructions and
at AMYLIN’s expense, LONZA will arrange for the shipment of Product by the carrier designated by AMYLIN and for appropriate shipping insurance, and LONZA shall ship Product in containers reasonably sufficient for delivery of Product in
accordance with Product Specifications.

 6.1     Not later than [...***...] after AMYLIN’s receipt of all LONZA Batch Release Documents, AMYLIN shall examine the LONZA Batch Release Documents for the Product’s
compliance with the Product Specifications and other warranties set forth in Section 8. Without AMYLIN’s written notice within such period, it is deemed that AMYLIN accepts the Product. 

  

***Confidential Treatment Requested 
 23 

 CONFIDENTIAL 
  

 If AMYLIN believes that any such shipment does not comply with the Product
Specifications or other warranties, or is otherwise deficient, AMYLIN shall promptly, but not later than [...***...] after receipt of all LONZA Batch Release Documents, notify LONZA. AMYLIN and LONZA will work together in good faith to resolve
any deviations from any manufacturing processes then in effect and to issue closed deviation reports for the Product. LONZA will evaluate process issues and other reasons for the deviations. Notwithstanding anything to the contrary set forth herein,
AMYLIN may reject any shipment of Product (or part thereof) that does not conform to the Product Specifications or other warranties in Section 8 (any Product failing to comply with the foregoing a “Defective Product”). Any such notice
of rejection shall be in writing and shall indicate the reasons for such rejection. Notwithstanding the foregoing, if there is subsequently found to be a Hidden Defect in any shipment of Product, AMYLIN shall promptly notify LONZA in writing and
AMYLIN and LONZA shall enter into discussions in good faith as to the handling and disposal of the defective shipment, having due regard to where responsibility for such defect lies, with the understanding that LONZA shall be responsible with
respect to matters existing prior to delivery of Product to AMYLIN. 
 6.2     LONZA shall
notify AMYLIN as promptly as reasonably possible, and in any event within [...***...] whether it accepts AMYLIN’s basis for any rejection or in good faith disagrees with AMYLIN’s determination that certain Product does not meet the
Product Specifications. If no such notice of dispute is received from LONZA, LONZA shall be deemed to have agreed that the rejection is necessary and justified. If there is a dispute as to the reasons for rejection of the Product, such Product shall
be submitted to a mutually acceptable third party laboratory. Such third party shall determine whether such Product meets the Product Specifications and other warranties set forth in Section 8, and the Parties agree that such third party’s
determination shall be final and determinative. The party against whom the third party tester rules shall bear all costs of the third party testing. Whether or not LONZA accepts

24 

 CONFIDENTIAL 
  

 
AMYLIN’s basis for rejection, promptly on receipt of a notice of rejection of Product, LONZA shall use commercially reasonable best efforts to replace such rejected Product, at its cost. If
the third party tester rules that the lot meets Product Specifications and the other warranties in Section 8, AMYLIN shall purchase that lot at the agreed-upon price, irrespective of whether LONZA has already replaced it. All replacement
Product shall be invoiced as well and AMYLIN is to pay for such product as otherwise provided under the terms of this Agreement. Upon acceptance by LONZA of AMYLIN’s rejection of Product or determination by the third party tester that the
Product does not meet the Production Specifications and other warranties in Section 8, AMYLIN shall promptly return said Product or quality control sample to LONZA, at LONZA’s cost based on LONZA’s instruction.

selected by it, provided the Indemnifying Party gives written notice to the Indemnified Party of its election to do so within twenty (20) days after receipt of notice in accordance with the preceding sentence. If the Indemnifying Party fails to
so notify the Indemnified Party of its election to defend any such Third Party claim, the Indemnified Party will (upon further notice to the Indemnifying Party) have the right to undertake the defense, compromise or settlement of such claim on
behalf of and for the account and expense of the Indemnifying Party, subject to the right of the Indemnifying Party to assume the defense of such claim at any time prior to settlement, compromise or final determination thereof if and only if such

shall include, without limitation, providing documents, making employees available for interviews, depositions and testimony and consultation on technical matters. 

9.3.3     An Indemnifying Party shall not under any circumstances, without the
written consent of the Indemnified Party, settle or compromise any claim or consent to the entry of any judgment which might in any material way prejudice or adversely affect the Indemnified Party or its continued business activities and which does
not include as an unconditional term thereof the giving by the claimant or the plaintiff to the Indemnified Party a release from all liability in respect of such claim, in form and substance reasonably satisfactory to the Indemnified Party.

 9.3.4     Notwithstanding anything to the contrary contained herein, with
respect to a Third Party claim that can be settled by the payment of money, if a Third Party claim is made which the Third Party is unequivocally willing to settle but an Indemnified Party elects not to settle, then the Indemnifying Party shall not
be liable hereunder, with respect to any Damage Claim arising from such Third Party claim, for more than the amount which such Third Party at any time unequivocally agrees in writing to accept in payment or compromise of the claim plus any related
costs and expenses incurred by the Indemnified Party as of the date of such offer of settlement. 
 9.3.5     All Damage Claims for indemnification hereunder shall be made in a written notice setting forth, with particularity, the nature of the claim for which indemnification is

 10.2     The nondisclosure and non-use obligations
of Paragraph 10.1 above shall not apply to Confidential Information which: 

(i)     is publicly known prior to disclosure or, subsequent to disclosure hereunder,
has become publicly known and the recipient can demonstrate became publicly known without fault on the part of the receiving party, 
 (ii)     the recipient can demonstrate was otherwise known by the receiving party prior to disclosure hereunder or was generated for the receiving party by persons who have not had

 (iii)    the
recipient party can demonstrate was received by the receiving party at any time from a source other than the disclosing party or its agents, lawfully having possession of such information and under no obligation of confidentiality with respect to
such information. 
 Notwithstanding Paragraph 10.1, the recipient party may disclose Confidential Information of the
disclosing party, without violating the obligations of this Agreement, to the extent the disclosure is required by a valid order of a court or other governmental body having jurisdiction, by any Governmental Agency or by Applicable Laws; provided
that, the recipient party gives reasonable prior written notice to the disclosing party of such required disclosure and cooperates with the disclosing party in obtaining, a protective order preventing or limiting the disclosure and/or requiring that

	11.	 Force Majeure 

 If the performance by either party of any obligation under this Agreement is prevented or impaired by an event of “Force Majeure”, such party shall be excused from performance so long as such
event continues to prevent or impair performance, provided the party claiming such excuse shall have promptly notified the other party of the existence, nature, expected duration and other significant details of such event and shall at all times use
diligent and commercially reasonable efforts to resume performance. If either party anticipates that a Force Majeure event may occur, that party shall notify the other immediately and explain the nature, significant details and expected duration
thereof. The party affected by an event of Force Majeure will advise the other from time to time as to its progress in remedying the situation and as to the time when the affected party expects to resume its performance of its obligations.
Additionally, the party affected by an event of Force Majeure shall notify the other party of the expiration of any event of Force Majeure as soon as the affected party knows the date thereof. For purposes hereof, an event of “Force
Majeure” shall mean an event beyond the reasonable control of a party including, but not limited to, fire, flood, sabotage, shipwreck, embargo, acts of terrorism, explosion, accident, riot, act of governmental authority, acts of God, acts of
war, and unusually severe weather; provided that, LONZA’s capacity constraints shall not be considered an event of Force Majeure hereunder. Notwithstanding the occurrence of a Force Majeure event, if LONZA shall be unable to supply during any
Contract Year any Product ordered by AMYLIN that is not in excess of the LONZA required capacity set forth in Section 2.2, AMYLIN and LONZA will consult with each other to determine what measures may reasonably be taken to solve the supply
problem. Notwithstanding the foregoing, if LONZA undergoes a Force Majeure event that results in LONZA failing to manufacture Product pursuant to any Purchase Order under this Agreement, the volume of any Product purchased by AMYLIN from alternate
Third-Party suppliers during the duration of the Force Majeure event shall be applied towards the minimum purchase amounts in Paragraph 2.3 above for the applicable Contract Year.

	17.	 Entire Agreement 

 This Agreement sets forth the entire agreement between AMYLIN and LONZA with respect to its subject matter, and fully supersedes any and all prior and contemporaneous agreements or understandings
pertaining to the subject matter hereof. 
  

	18.	 Severability 

 A determination that any portion of this Agreement is unenforceable or invalid shall not affect the enforceability or validity of any of the remaining portions hereof or of this Agreement as a whole,
unless such unenforceability or invalidity goes to the essence of the agreement between the parties, in which case this Agreement shall be and become null and void as and from the date of such unenforceability or invalidity. In the event that any
part of any of the covenants, sections or provisions herein may be determined by a court of law or equity to be overly broad or against applicable precedent or public policy, thereby making such covenants, sections or provisions invalid or
unenforceable, and such determination does not go to the essence of this Agreement for either one of the parties hereto, then the parties shall attempt to reach agreement with respect to a valid and enforceable substitute for the deleted provisions,
which shall be as close in its intent and effect as possible to the deleted portions. 
  

	19.	 Waiver - Modification of Agreement 

No waiver or modification of any of the terms of this Agreement shall be valid unless in writing and signed by authorized
representatives of both parties hereto. No course of dealing or usage of trade shall be applicable unless expressly incorporated in this Agreement. Failure by 

  
 39 

 CONFIDENTIAL 
  

 
either party on any occasion to enforce any rights under this Agreement shall not be construed as a waiver of such rights nor shall a waiver by either party in one or more instances be construed
as constituting a continuing waiver or as a waiver in other instances. 
  

	20.	 Publicity 

 In the absence of specific agreement between the parties, neither party shall originate any publicity, news release or other public announcement, written or oral, whether to the public press, to
stockholders or otherwise relating to this Agreement or to performance hereunder, save only such announcement as in the opinion of legal counsel to the party making such announcement is required by law to be made. 

 

	21.	 Exhibits 

 All Exhibits referenced herein are hereby made a part of this Agreement. 
  

	22.	 Counterparts

interpretation of any part hereof.

be in New York, New York, USA, and the language that the proceedings are held in shall be English. The decision or award rendered by the arbitrator shall be final and non-appealable, and judgment may be entered upon it in any court of competent

	2.	 Amendment to Provisions Regarding Purchase and Sale of Product. 

2.1     Amendment to Purchase Order Procedures. Paragraph 2.2 of the Agreement is hereby
amended and restated in its entirety as follows: 
 “2.2     LONZA
agrees to manufacture and supply to AMYLIN the amounts of Product (subject to the minimum percentage of AMYLIN’s total annual requirements of Product as set forth in Paragraph 2.3 below) as ordered by AMYLIN pursuant to written purchase
orders issued hereunder by AMYLIN (“Purchase Order”), specifying the quantity, Nominal Lot quantity, and delivery date. The weight of Product shall be determined according to net peptide weight (“NPW”). AMYLIN shall submit each
Purchase Order to LONZA at least [...***...] in advance of the shipment date specified in the Purchase Order and otherwise in accordance with the requirements hereof; provided that for the manufacturing campaign using fragments already
produced as of April 1, 2009 resuming production in 2010, AMYLIN shall submit the Purchase Order to LONZA [...***...] in advance of the shipment date specified in such Purchase Order. Within [...***...] of LONZA’s receipt of a

change to a Purchase Order after written confirmation of receipt, LONZA shall use commercially reasonable efforts to accommodate such request. Notwithstanding any other provision hereof, except

either party that is in any manner additional to, different from or varies the terms and conditions hereof shall be deemed to be of any force or effect. LONZA agrees that it will be able to manufacture at least [...***...] of Product per

2.2     Amendment to Purchase Obligations. Paragraph 2.3 of the Agreement is hereby
amended and restated in its entirety as follows: 
 “2.3 AMYLIN agrees to purchase from

 (1)     For
Contract Years 2010 through and including 2012, AMYLIN’s total annual Product requirements exclude all quantities of Product [...***...]. 

Notwithstanding the above, AMYLIN shall not be required to purchase Product under this Agreement in the
event that: 
 (i)     LONZA has not manufactured and delivered all Product
Validation Lots meeting all Product Requirements in accordance with the Development Agreement, 

(ii)     LONZA is not an FDA approved commercial supplier of Product or fails to
successfully complete its Pre-Approval Inspection or equivalent non-United States inspection, 

(iii)     the FDA or other applicable Government Agency does not approve the NDA
filed in the United States relative to Product, 
 (iv)     AMYLIN withdraws
the NDA relative to the Product, or

in progress which LONZA, despite best commercial efforts, cannot utilize for other customers.

 The Executive Steering Committee will
assess compliance with the Performance Criteria on a regular basis and, in the event of non-compliance, monitor plans to re-establish compliance. The parties will, through the Executive Steering Committee, discuss how to resolve difficult issues
relating to compliance with the Performance Criteria. Any failure to comply with the Performance Criteria is expected to be corrected within no more than a [...***...] duration. If non-compliance with the Performance Criteria persists beyond a
[...***...] duration, the parties will discuss corrective measures and AMYLIN will have the right to reduce the percentage of AMYLIN’s annual Product requirements allocated to LONZA under this Agreement to a level determined by AMYLIN. If
AMYLIN does not purchase at least the percentage of AMYLIN’s total annual requirements of Product specified above due to any failure to deliver Product in accordance with the Performance Criteria, it will not be deemed a breach of this
Paragraph 2.3 or any other provision of this Agreement. 
 LONZA shall have the right, upon
reasonable advance notice to AMYLIN, to have an independent Third Party reasonably acceptable to AMYLIN audit the books and records of AMYLIN with respect to any Contract Year ending not more than [...***...] prior to the date of notice
requesting an audit to confirm through its review of forecasts, contracts, purchase orders, invoices and other documentation reasonably related to Product purchases that AMYLIN has complied with its obligations under this Paragraph 2.3.

 Should AMYLIN in any Contract Year purchase less than
the required minimum percentage of AMYLIN’s annual Product requirements set forth above (unless due to any failure to deliver Product in accordance with the Performance Criteria), AMYLIN will make up any shortage as soon as practicable
following discovery of such shortage.” 
 2.3     Amendment to Product Price.
Paragraph 2.4 of the Agreement is hereby amended and restated in its entirety as follows: 

“2.4 For each [...***...] of Product supplied hereunder by LONZA, AMYLIN will pay to LONZA a

Contract Year will be at the applicable price for Product based on the most recent [...***...] submitted by AMYLIN prior to the shipment by LONZA of any such amount of Product. All prices are calculated and shall be paid in Swiss Francs (CHF).
Based on the foregoing, AMYLIN will pay to LONZA a [...***...] price for Product (“Product Price”) in accordance with the table below and in accordance with Product ordered for delivery in a Contract Year.

2.5     Future Overage/Underage. Paragraph 2.5 of the Agreement is hereby amended and
restated in its entirety as follows: 
 “2.5     In the event the
amount of Product delivered by LONZA pursuant to any purchase order is less than the amount of Product ordered by such purchase order, LONZA will use its best commercial efforts to supply the amount of Product ordered but not delivered as soon as is
feasible. In the event the amount of Product manufactured by LONZA pursuant to any purchase order is less than [...***...] greater than the amount of Product ordered by such purchase order, LONZA shall deliver such additional amounts of
Product to AMYLIN as if AMYLIN had ordered them pursuant to such purchase order. In the event the amount of Product manufactured by LONZA pursuant to any purchase order is equal to or more than [...***...], but less than or equal to
[...***...], greater than the amount of Product ordered by such purchase order, LONZA shall deliver such additional amounts of Product to AMYLIN as early delivery of Product ordered by AMYLIN on the next purchase order pursuant to which AMYLIN
has ordered Product. In the event the amount of Product manufactured by LONZA pursuant to any purchase order is more than [...***...] greater than the amount of Product ordered by such purchase order, LONZA and AMYLIN shall negotiate in good
