AECOM will take all necessary action to reserve for Licensee exclusive rights to the technology developed by Investigator in the Field under the sponsorship of the government (and licensed to Licensee hereunder), with the proviso that such reservation shall be to the extent permitted under 35 U.S.C. Section 200 et. seq. and applicable regulations.

2.02		The continuance of such government sponsored research by AECOM and its Investigator during the term of this Agreement will not constitute a breach of this Agreement. All rights reserved to the U.S. Government under 35 U.S.C. §200 et. seq. and applicable regulations shall remain so reserved and shall in no way be affected by this Agreement. AECOM and its Investigator are not obligated under this Agreement to take any action which would conflict in any respect with their past, current or future obligations to the U.S. Government as to work already performed and to be performed in the future.

In the event that Licensee elects not to maintain or prosecute any patent or patent application within the Agreement Patents, Licensee shall give Licensor thirty (30) days prior written notice of such

		election. Any patents or patent applications so elected shall at the end of the notice period cease to be considered Agreement Patents, and Licensor shall then be free, at its election, to abandon or maintain the prosecution of such patent application or issued patent or grant rights to such patent application or issued patent to third parties. Licensee will also pay the costs of filing and prosecuting the foreign patent applications listed as Nos. 6, 7, 8, 9, 10 and 11 on Appendix A incurred by Licensors between * and the Effective Date, up to a maximum of * Dollars ($***).

Within thirty (30) business days of Licensee’s receipt of an Option Invention disclosure, Licensee will provide written notification to Licensors that either:

(a)

Licensee is not interested in expanding Agreement Patents to include the Option Invention, in which event Licensee’s option with respect to the subject Option Invention shall immediately expire; or

10.06		If Licensee terminates this Agreement pursuant to paragraph 10.02 or if Licensors terminate this Agreement pursuant to paragraphs 10.03 or 10.04, then Licensee hereby grants to Licensors, or shall use commercially reasonable efforts to procure for Licensors, a worldwide, royalty-bearing, non-exclusive license, with the right to grant sublicenses, under any Improvement Patents or Improvement Know-How (as defined below) developed by or for Licensee or its Affiliates during the term of this Agreement. As used in this paragraph, the term “Improvement Patents” means any U.S. or foreign patent application or patent which claims an invention the practice of which would be covered by a claim of patent or patent application of Agreement Patents, or practice of which results in a product covered by a claim of a patent or patent application of Agreement Patents. “Improvement Know How” means confidential information, including clinical trial information, the practical application of which would be covered by a claim of a patent or patent application of Agreement Patents, or which results in a product covered by a claim of a patent or patent application of Agreement Patents. The royalty-rate for such license shall be determined by good faith negotiations between the parties and which shall not exceed Licensee’s obligations under this agreement including license fees, milestone payments and royalty obligations. Further, Licensors shall bear the cost of any license procured from a third party by Licensee for the benefit of Licensors, so long as such license is accepted by Licensors.

Statement

Licensors and Licensee are parties to a License Agreement dated June 27, 2000, as amended by a First Amendment Agreement effective July 26, 2002 (collectively “the License Agreement”), and now wish to make changes to the License Agreement.

NOW, THEREFORE, in consideration of the mutual covenants contained in the License Agreement and in this Second Amendment Agreement and other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1. Subparagraph 6.05(b) of the License Agreement is hereby amended to read as follows:

(b)

Except as specified below, upon the initiation by Licensee (or an Affiliate) of Phase II clinical trials (i.e. the administration of a Licensed Product to a patient for the primary purpose of assessing clinical efficacy; and not Phase I clinical trials for the primary purpose of assessing safety or pharmacokinetics) for each Licensed Product (or each indication for a Licensed Product), Licensee shall pay to Licensors *** Dollars (US$***),
