NOW, THEREFORE, the Parties hereto agree as follows: 1. PURCHASE AND SALE. Subject to the terms and conditions hereof, and in reliance upon the representations, warranties and agreements contained herein, Corixa hereby agrees to issue and sell to Purchaser, and Purchaser hereby agrees to purchase from Corixa, the aggregate number of shares of Common Stock determined in accordance with Section 1.1 hereof. 1.1 SALE OF SHARES. On the First Closing Date (as defined in Section 1.3), Corixa shall issue and sell to Purchaser, and Purchaser shall purchase from Corixa that number of shares of Common Stock (the "First Closing Shares") equal to the quotient of $5,000,000 divided by the First Closing Purchase Price (as hereinafter defined).
