* CONFIDENTIAL TREATMENT REQUEST(ED)

other applicable United States or foreign laws, rules and regulations, will not be accepted by AMYLIN. In an attempt to meet Product Specifications for each Lot of Product rejected by AMYLIN pursuant to Paragraph 4.5, UCB may reprocess such material if there is a validated process to reprocess the Lot and AMYLIN agrees in advance to the reprocessing of the Lot. Product Specifications shall not be modified without AMYLIN’s prior written agreement. UCB shall promptly advise AMYLIN of any Major Changes, including Major Changes to any processes or in-process testing proposed by UCB for the manufacture of Product. No such Major Changes will be implemented by UCB unless AMYLIN has agreed to such changes in writing in advance. UCB will not change the vendors of, or the acceptance criteria for, any raw materials used in the manufacture of Product without prior approval from AMYLIN.

4.3 Testing. On or before the date specified in each Firm Purchase Order for delivery of each Lot, UCB shall deliver samples (in sample sizes specified by AMYLIN) of such Lot of Product to AMYLIN for testing (“Testing Samples”). The Testing Samples will be prepared and packed by UCB in accordance with AMYLIN’s applicable standard operating procedures then in effect. If such Lot is accepted by AMYLIN in accordance with Paragraph 4.5, UCB shall promptly deliver the remainder of such Lot of Product (“Commercial Material”) to a carrier specified by AMYLIN for shipment to the location(s) specified by AMYLIN. Each Lot of Commercial Material will be packed by UCB in accordance with AMYLIN’s applicable standard operating procedures then in effect. For any amendment to such standard operating procedures applicable to shipping Testing Samples, the associated costs shall be reviewed in good faith by the parties and if the parties determine that such amendment results in significant increased shipping costs, then AMYLIN shall be responsible for payment

of the amount of the increase. UCB shall prepare Product for shipment and arrange for shipment of Testing Samples and Commercial Material. AMYLIN shall pay all reasonable delivery charges for Testing Samples and Commercial Material, provided that such delivery charges are supported with receipts documenting such delivery charges and that such deliveries were made in accordance with AMYLIN’s instructions. Each shipment must be accompanied by a packing slip which describes the articles, states the purchase order number and shows the shipment’s destination. UCB agrees promptly to forward the original ▇▇▇▇ of lading or other shipping receipt for each shipment in accordance with AMYLIN’s written instructions.

4.4 Shipment and Delivery. The Product to be furnished pursuant to this Agreement (including both the Testing Samples and Commercial Material referenced in Paragraph 4.3 above), shall be shipped FCA (Incoterms 2000) UCB’s facilities, [***]. Each delivery of Product shall be governed by the terms of this Agreement, and none of the conflicting terms or conditions of AMYLIN’s Firm Purchase Order form or UCB’s purchase order form, acknowledgment or invoice form shall be applicable, except those specifying special shipping instructions and invoice information.

4.5 Acceptance of Product. Not later than ninety (90) days after receipt of Testing Samples for each Lot of Product, AMYLIN shall examine such Testing Samples for compliance with the Product Specifications, and any damage, defects or shortage. If AMYLIN believes that any such Testing Samples do not comply with the Product Specifications or are otherwise deficient, AMYLIN shall promptly, but not later than ninety (90) days from receipt of such Testing Samples (which period may be extendible should AMYLIN be able to justify to UCB that an unusual situation arose which made it not possible for

* CONFIDENTIAL TREATMENT REQUEST(ED)

AMYLIN to determine whether or not the Testing Samples are in compliance with Product Specifications after receipt of the shipment), notify UCB. The 90-day period referred to in the preceding two sentences shall be reevaluated after 2004 to determine whether or not 90 days is a reasonable period of time. In any case, on or before the end of 2004, AMYLIN agrees to make its reasonable efforts to reduce this 90-day testing period.

If UCB is satisfied that the relevant Testing Samples do not comply with the representations and warranties in Paragraph 4.2 (including Product Specifications) or are otherwise deficient, AMYLIN shall dispose of the non-complying Testing Samples as UCB shall lawfully direct and at UCB’s sole cost and expense, and UCB shall upon request from AMYLIN, and at AMYLIN’s option, replace the shipment or remedy the deficiency promptly, at UCB’s sole cost and expense. UCB shall not be liable, however, for any incidental or consequential damages associated with a non-complying Lot of Product.

If UCB should deny that the relevant Lot of Product does not comply with any of the representations and warranties in Paragraph 4.2 (including Product Specifications) or is otherwise deficient or should admit such non-compliance or deficiency but deny that it is at fault, UCB and AMYLIN may submit documentation regarding the relevant Lot of Product to an independent expert agreed upon by the parties, and the decision of this independent expert shall be final and binding upon the parties. The fees of such expert shall be borne by the losing party. Failure of AMYLIN to notify UCB of a claim, non-compliance or deficiency as set forth under this Agreement shall constitute acceptance of such Lot of Product subject to Paragraph 4.6.

Title and risk of the Product will be transferred to AMYLIN upon delivery of the Testing Samples and the Commercial Material to a carrier specified by AMYLIN as referred to in Paragraph 4.4 above.

4.6 Hidden Defect. If there is subsequently found to be a defect in any Lot of Product, which could not reasonably be expected to have been found by diligent and adequate inspection by AMYLIN pursuant to its obligations under this Article, such as stability or the presence of any Contaminant (a “Hidden Defect”), the party discovering the Hidden Defect shall notify the other party (“Hidden Defect Notice”), and AMYLIN and UCB shall enter into discussions in good faith about what action should be taken, if any (including actions as to the handling and disposal of the defective Lot). If the Hidden Defect is caused by UCB’s negligence, acts or omissions, then, in addition to any other remedies available to AMYLIN, AMYLIN shall have the right to require UCB, at AMYLIN’s election, to either (A) replace the defective Product (any such replacement shall be at the sole cost and expense of UCB and occur promptly but in no event later than ninety (90) days after the date of the Hidden Defect Notice), or (B) refund AMYLIN an amount equal to the price paid by AMYLIN for the defective Product.

4.7 Invoice. UCB shall invoice AMYLIN with a single invoice upon delivery of Testing Samples for each Lot of Product at the address to be specified by AMYLIN in writing on its Firm Purchase Order. AMYLIN shall pay UCB on the earlier of (A) [***] (or if extended based on an unusual situation pursuant to Paragraph 4.5, such longer extended time period) of its receipt of the invoice, and (B) AMYLIN’s acceptance of

* CONFIDENTIAL TREATMENT REQUEST(ED)

the Lot; provided that the Lot of Product is not definitively rejected as described in Paragraph 4.5.

To the extent an indemnified party makes a claim for indemnification hereunder, the indemnified party shall give written notice to the indemnifying party reasonably setting forth the facts and circumstances in connection with the claim for indemnification.

In the event of UCB’s assignment to a UCB Affiliate, UCB shall remain liable for such Affiliate’s performance of this Agreement. Any consent that AMYLIN elects to provide under this Paragraph 14.1 shall not be provided unless and until UCB furnishes AMYLIN with a copy of the proposed assignment.

ARTICLE XV - TERM & TERMINATION

15.1 Term. This Agreement shall remain in effect, unless earlier terminated pursuant to the provisions of this Article or Article XVII, for an initial period of eight (8) years starting from the Effective Date. Thereafter, it shall be automatically renewed for consecutive one (1) year periods unless either party gives written notice at least thirty-six (36) months prior to the expiration of the initial term or any consecutive renewal period.

15.2 Breach. Either party, at its option, may terminate this Agreement for default if any of the following acts of default occur: (1) the other party is in material breach of this Agreement, which breach is not cured within sixty (60) days of notice of such breach by the terminating party; or (2) the other party becomes insolvent or a petition under bankruptcy act or similar statute is filed by or against the other party and is not vacated within thirty (30) days after such filing.

15.3 AMYLIN Termination. Upon thirty (30) days prior written notice to UCB, AMYLIN may terminate this Agreement at any time after the Effective Date should it determine that the development and/or commercialization of pramlintide will not continue. Termination under this Paragraph 15.3 shall not

relieve AMYLIN of its obligation to purchase Product pursuant to an issued Firm Purchase Order.

15.4 Remedies. The rights and remedies of the parties provided in this Article XV are in addition to any other rights and remedies provided by law or under this Agreement.

ARTICLE XVI - CALENDAR DATES

All periods of days referred to in this Agreement shall be measured in calendar days.

ARTICLE XVII - FORCE MAJEURE

If the performance by a 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 party immediately and explain the nature, details and expected duration thereof.

The affected party will advise the other party 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 an event beyond the reasonable control of a party including, but not limited to, fire, flood, sabotage, shipwreck, embargo, explosion, accident, riot, act of governmental authority, acts of God and acts of war.

In the event of a Force Majeure affecting UCB, UCB may prorate and allocate its supply of manufacturing resources among its Affiliates and its then current contract customers, and in such manner as may be deemed fair and reasonable based upon purchases over the past year.

If, as a result of a Force Majeure event, UCB is unable to supply Product in such quantities as AMYLIN shall request and in compliance with the delivery periods set forth in this Agreement, UCB and AMYLIN will consult with each other to determine what measures to take to solve the supply problem with the understanding that it may be necessary for AMYLIN to obtain supply from a Third Party source using UCB Technology in accordance with Article IX, and in such event, AMYLIN shall be permitted (with no obligation to UCB) to obtain Product from such Third Party source and require UCB to transfer UCB Technology and provide the training required and described in Article IX. As soon as the Force Majeure event affecting UCB’s ability to supply Product terminates, (i) UCB shall provide written notice thereof to AMYLIN so that AMYLIN may resume issuing Firm Purchase Orders to UCB in accordance with Paragraph 3.4, and (ii) within sixty (60) days of AMYLIN’s receipt from UCB of Product ordered under the first Firm Purchase Order issued after the termination of the Force Majeure event, such Third Party source’s right to use UCB

Technology to supply Product to AMYLIN shall terminate. If the Force Majeure event affecting UCB’s ability to supply Product under this Agreement persists for a period of 540 consecutive days, then AMYLIN shall have the right to terminate this Agreement by providing written notice to UCB, and the terms of Paragraph 8.2 and Article IX shall apply.

ARTICLE XVIII - CHANGES

AMYLIN ‘s personnel may, from time to time, render assistance or give technical advice to, or effect an exchange of information with UCB’s personnel in a liaison effort concerning the work hereunder. However, such exchange of information or advice shall not vest UCB with authority to change the work hereunder or the provisions of this Agreement, nor shall any change in the work or provisions of this Agreement be binding on AMYLIN unless effected as a modification in accordance with the terms of this Agreement.

ARTICLE XXII - NOTICE TO AMYLIN OF POSSIBLE DELAYS

Whenever UCB has knowledge or a reasonable belief that any actual or potential condition is delaying or threatens to delay the timely performance of this Agreement, it shall immediately give notice thereof, including all relevant information with respect thereto, to AMYLIN, and shall identify in detail the steps being taken to remedy the condition and when such remedy is anticipated to be completed and delivery accomplished.
