Item 1.01.              Entry into a Material Definitive Agreement.

 

On October 24, 2005, Rigel Pharmaceuticals, Inc. (“Rigel”) entered into a collaborative research and license agreement with Ares Trading S.A. (“Ares”), a wholly-owned subsidiary of Serono S.A., to develop and commercialize product candidates from Rigel’s Aurora kinase inhibitor program.

 

A copy of the press release further describing this collaboration is filed as Exhibit 99.1 to this report and is incorporated herein by reference.

 

Item 3.02.              Unregistered Sales of Equity Securities.

 

On October 24, 2005, Rigel entered into a common stock purchase agreement with Ares, pursuant to which Rigel will issue to Ares 546,018 shares of Rigel’s common stock for an aggregate purchase price of $15,000,000, payable in cash. The closing of the sale is to occur within 10 business days of the execution of the agreement.  The shares of common stock will be issued in reliance upon an exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Rule 506 of Regulation D promulgated under Section 4(2) of the Securities Act. Rigel determined that this exemption was available based on the representations and warranties made by Ares regarding its investment intent, experience and sophistication, including representations regarding Ares’ qualification as an “accredited investor,” as such term is defined under Rule 501 promulgated under the Securities Act.  In addition, the terms of the sale otherwise meet the requirements for the Rule 506 exemption
