Upon such application, Amylin shall be deemed to have discharged
outstanding Indebtedness in an amount equal to that applied against Lillys
share of the Impairment Charge. 
Notwithstanding anything to the contrary, if Amylin or Amylin Ohio LLC
incurs an Impairment Charge at any time during the Advance Period, Amylin shall
be deemed, without any further action or notice required hereunder, to have
forfeited its right to make any additional Borrowing Requests of Lilly.  3.6Payments

that any payment of any principal, interest, fees or any other amounts payable
by Amylin under or pursuant to this Loan Agreement, or under any other Loan

applicable, interest shall continue to accrue and be payable at the applicable
rate(s) for and during any such extension.  3.7Payment
Procedures.  All sums payable by
Amylin to Lilly under or pursuant to this Loan Agreement, or any other Loan

funds, and without setoff, deduction or counterclaim.  3.8Optional
Prepayments.  Amylin may prepay the
outstanding Indebtedness, in whole or in part, without premium or penalty, at
any time and from time to time.  Any
partial prepayment shall be applied first to any Indebtedness consisting of
amounts other than principal and interest, second to accrued but unpaid
interest and finally to outstanding principal. 
Any partial prepayment applied to outstanding principal shall be deemed
applied to the outstanding Advances in the order in which they were made.  3.9Collection

of Amylin included in its SEC Filings correctly and fairly present the
financial condition, results of operations and cash flows of Amylin as of the
dates and for the periods shown and covered thereby, in accordance with GAAP
