Employer Identification No.) 92121-1117 (Zip Code) Item 5. Other Events On April 1, 2002, the Company received notice from a collaboration partner of its intent to sell up to 3,023,329 shares of our common stock, of which 412,504 shares are subject to Rule 144 restrictions. We have a right, exercisable for five (5) business days following the notice, to purchase all or none of those shares at prices specified on our stock purchase agreement with the partner. The Company has elected not to exercise its purchase rights. Under the stock purchase agreement, and following our election, the partner may sell the shares to others at any time within ninety (90) days of the expiration of its offer to the Company. Unless otherwise agreed, if all of the shares are not sold during those 90 days, our partner must submit subsequent offer notices to the Company. Absent such agreement, we anticipate that our partner will continue to submit such offer notices to the extent it does not sell all of the shares of our common stock during the current 90-day period. We have in the past received such notices from this partner and other partners. In some cases our partners, including this partner, did not sell shares following their notices to us. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has caused this report to be signed on its behalf by the undersigned.
