GOVERNMENT RIGHTS. This Agreement is subject to all of the terms and conditions of Title 35 United States Code Sections 200 through 204, including an obligation that Licensed Product(s) sold or produced in the United States be "manufactured substantially in the United States," and RIGEL agrees to take all reasonable action necessary on its part as licensee to enable STANFORD to satisfy its obligation thereunder. STANFORD agrees to provide reasonable assistance to RIGEL in the event RIGEL decides to seek a waiver under such domestic manufacture requirement. 5. DILIGENCE. 5.1 As an inducement to STANFORD to enter into this Agreement, RIGEL agrees to use all reasonable efforts and diligence to proceed with the development, manufacture and sale of Licensed Product(s) and to develop diligently markets for the Licensed Product(s). RIGEL shall demonstrate such diligence to STANFORD by achieving proof of principle though written documentation of the following achievements: (a) Construction of a retroviral vector library; (b) Infection of cells with such vector library; (c) Detection of a physiological response to such infection in an infected cell; [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 OF THE SECURITIES ACT OF 1933, AS AMENDED. 3 <PAGE> (d) Isolation and analysis of the peptide eliciting such physiological response from the cell; and (e) Identification of two novel targets for drug design, or demonstration that two previously known targets have a novel activity suitable for drug design. 5.2 If RIGEL is unable to demonstrate items 5.1(a) through (d) within eighteen (18) months after the Effective Date, and item 5.1(e) within thirty six (36) months after the Effective Date, STANFORD may request that RIGEL meet with STANFORD to discuss RIGEL's lack of diligence. The parties shall meet within thirty (30) days after RIGEL receives any such notice to develop a mutually agreeable plan for remedying any such lack of diligence (the "Proposed Remedy"). If RIGEL fails to perform the Proposed Remedy within one hundred eighty (180) days after the Proposed Remedy is agreed upon, STANFORD may elect to terminate this Agreement, which termination shall not have any effect upon the rights granted to RIGEL pursuant to the 1996 License Agreement. 5.3 On or before each anniversary of the Effective Date during the Exclusivity Term, RIGEL shall make a written annual report to STANFORD covering RIGEL's progress during the preceding year toward commercial use of the Licensed Product(s). Such report shall include as a minimum information sufficient to enable STANFORD to satisfy relevant reporting requirements of the U.S. Government and to ascertain RIGEL's progress toward meeting the diligence requirements of this Article 5. 6. LICENSE FEE AND ROYALTIES. 6.1 In partial consideration for the Exclusive License granted by STANFORD to RIGEL with respect to the [ * ] cell lines included in the Materials, RIGEL agrees to pay to STANFORD the following: (a) A noncreditable, nonrefundable license issue royalty of ______________________, which amount shall be paid within thirty (30) days after the Effective Date.
