Summary Description of Named Executive Officer
Oral At-Will Employment Agreement

Foletta, Orville G. Kolterman, M.D., Marcea Bland Lloyd and Roger Marchetti. Each of these executive officers receives our normal and customary employment benefits, generally on the same terms as all of our employees. The benefits include the right to (i) participate in our 401(k) Plan and our Employee Stock Purchase Plan, (ii) receive 10% of eligible compensation in the form of Amylin common stock under our Employee Stock Ownership Plan and (iii) receive stock option grants under our Equity Incentive Plan and cash bonuses under our cash bonus plan. The cash bonus plan is called the Executive Cash Bonus Plan when it applies to those employees with the title of executive director or above
