Licensee may request the Government to initiate or join in any such suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any such suit, Licensee shall reimburse the Government for any costs, expenses, or fees which the Government incurs as a result of such motion or other action, including any and all reasonable costs incurred by the Government in opposing any such motion or other action. In all cases, Licensee agrees to keep PHS reasonably apprised of the status and progress of any litigation. Before Licensee commences an infringement action, Licensee shall notify PHS and give careful consideration to the views of PHS and to any potential effects of the litigation on the public health in deciding whether to bring suit.

11.03

In the event that a declaratory judgment action alleging invalidity or non-infringement of any of the Licensed Patent Rights shall be brought against Licensee or raised by way of counterclaim or affirmative defense in an infringement suit brought by Licensee under Paragraph 11.02, pursuant to this Agreement and the provisions of Chapter 29 of Xxxxx 00, Xxxxxx Xxxxxx Code or other statutes, Licensee may a) defend the suit in its own name, at its own expense, and on its own behalf for presumably valid claims in the Licensed Patent Rights; b) in any such suit, ultimately to enjoin infringement and to collect for its use, damages, profits, and awards of whatever nature recoverable for such infringement; and c) settle any claim or suit for declaratory judgment involving the Licensed Patent Rights-provided, however, that PHS and appropriate Government authorities shall have the first right to take such actions and shall have a continuing right to intervene in such suit. If PHS does not notify Licensee of its intent to respond to the legal action within a reasonable time, Licensee will be free to do so. Licensee shall take no action to compel the Government either to initiate or to join in any such declaratory judgment action. Licensee may request the Government to initiate or to join any such suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any such suit by motion or any other action of Licensee, Licensee shall reimburse the Government for any costs, expenses, or fees which the Government incurs as a result of such motion or other action. If Licensee elects not to defend against such declaratory judgment action, PHS, at its option, may do so at its own expense. In all cases, Licensee agrees to keep PHS reasonably apprised of the status and progress of any litigation. Before Licensee commences an infringement action, Licensee shall notify PITS and give careful consideration to the views of PHS and to any potential effects of the litigation on the public health in deciding whether to bring suit.

11.04

In any action under Paragraphs 11.02 or 11.03, the expenses including costs, fees, attorney fees, and disbursements, shall be paid by Licensee. Up to fifty percent (50%) of such expenses may be credited against the royalties payable to PHS under Paragraph 6.03 under the Licensed Patent Rights in the country in which such a suit is filed. In the event that fifty percent (50%) of such expenses exceed the amount of royalties payable by Licensee in any calendar year, the expenses in excess may be carried over as a credit on the same basis into succeeding calendar years. A credit against litigation expenses, however, may not reduce the royalties due in any calendar year to less than the minimum annual royalty. Any recovery made by Licensee, through court judgment or settlement, first shall be applied to reimburse PHS for royalties withheld as a credit against litigation expenses and then to reimburse Licensee for its litigation expense. Any remaining recoveries shall be shared equally by Licensee and PHS to the extent the legal action relates to the Licensed Patent Rights.

11.05

PHS shall cooperate fully with Licensee in connection with any action under Paragraphs 11.02 or 11.03. PHS agrees promptly to provide access to all necessary documents and to render reasonable assistance in response to a request by Licensee.

Licensee agrees to maintain a liability insurance program consistent with sound business practice. Notwithstanding any other provision to the contrary, Licensee shall have no obligation to indemnify and hold harmless PHS, its employees, students, fellows, agents, and consultants in connection with or arising out of the grossly negligent mishandling of Licensed Products, Licensed Processes or materials by PHS, its employees, students, fellows, agents, and consultants.

13.02

In the event that Licensee is in default in the performance of any material obligations under this Agreement, including but not limited to the obligations listed in Article 13.05, and if the default has not been remedied within ninety (90) days after the date of notice in writing of such default, PHS may terminate this Agreement by written notice,

Licensee shall have a unilateral right to terminate this Agreement and/or any licenses in any country by giving PHS sixty (60) days written notice to that effect.

13.05

PHS shall specifically have the right to terminate or modify, at its option, this Agreement, if PHS determines that the Licensee: 1) is not using reasonable best efforts in executing the Commercial Development Plan submitted with its request for a license and the Licensee cannot otherwise demonstrate to PIIS's satisfaction that the Licensee has taken, or can be expected to take svizlein a reasonable time, effective steps to achieve Practical Application of the Licensed Products or Licensed Processes; 2) has not achieved the Benchmarks as may be modified from time to time by prior mutual written consent under Paragraph 9.02; 3) has willfully made a false statement of, or willfully omitted, a material fact in the license application or in any report required by the license agreement; 4) has committed a material breach of a covenant or agreement contained in the license; 5) is not keeping Licensed Products or Licensed Processes reasonably available to the public after commercial use commences; 6) cannot reasonably satisfy unmet health and safety needs; or 7) cannot reasonably justify a failure to comply with the domestic production requirement of Paragraph 5.02 unless waived.

13.06

When the public health and safety so require, and after written notice to Licensee providing Licensee a sixty (60) day opportunity to respond, PHS shall have the right to require Licensee to grant sublicenses to responsible applicants, on reasonable terms, in any Licensed Fields of Use under the Licensed Patent Rights, unless Licensee can reasonably demonstrate that the granting of the sublicense would not materially increase the availability to the public of the subject matter of the Licensed Patent Rights. PHS will not require the granting of a sublicense unless the responsible applicant has first negotiated in good faith with Licensee.

Model PHS Patent License Agreement--Exclusive—Angiotech Pharmaceuticals, Inc.

Form 121895 Page 22 of 27 (1,103-96/11) (FINAL) CONFIDENTIAL 19971117

[***] (US$[***]) U.S. Dollars, payable within ninety (90) days of receipt thereof, wherein "any consideration" includes:

All payments received by the Licensee from a sublicensee under the terms and conditions of the sublicense, excluding; (i) earned royalties, (ii) minimum annual royalties to the extent that the total of all minimum annual royalties collected from all subticensees total less than or equal to the corresponding minimum annual royalties payable to the PHS by the Licensee under this Appendix C and to the extent that the minimum annual royalties represent actual earned royalties (iii) reimbursements for research and development expenses and other direct costs incurred by the Licensee to the extent that Licensee has not previously received any consideration or reimbursement for such expenses, (iv) the fair market value of equity investments by the sublicensee in the Licensee; and (v) any payments from any sublicensee to Licensee that correspond with and to the extent such payments are equal to or less than any royalties payable by Licensee to PHS as set forth in Section IV above of this Appendix C.

For "any consideration" received by Licensee from its sublicensee(s) relating to any Combined Product, the percentage of such consideration that PHS shall be entitled to pursuant to this section shall be adjusted by multiplying [***] percent ([***] %) by the fraction (based on the sale price of the Combined Product) a/(a+b), where a is the total market price of the Licensed Product if sold separately and b is the total market price of any other active product or component in the Combined Product if sold separately.
