STATUTORY AND PHS REQUIREMENTS AND RESERVED GOVERNMENT RIGHTS 5.01 (a) PHS reserves on behalf of the Government an irrevocable, nonexclusive, nontransferable, royalty-free license for the practice of all inventions licensed under the Licensed Patent Rights and/or Background Patent Rights throughout the world by or on behalf of the Government and on behalf of any foreign government or international organization pursuant to any existing or future treaty or agreement to which the Government is a signatory. Prior to the First Commercial Sale, Licensee agrees to provide PHS with quantities of Licensed Products or materials made by the Licensed Processes for PHS research use and/or for PHS use in conducting pre-clinical, Phase I, Phase II, Phase III Clinical Trials. (b) In the event that Licensed Patent Rights are Subject Inventions made under a Cooperative Research and Development Agreement (CRADA), Licensee grants to the Government, pursuant to 15 U.S.C. 3710a(b)(1)(A), a nonexclusive, nontransferable, irrevocable, paid-up license to practice Licensed Patent Rights or have Licensed Patent Rights practiced throughout the world by or on behalf of the Government. In the exercise of such license, the Government shall not publicly disclose trade secrets or commercial or financial information that is privileged or confidential within the meaning of 5 U.S.C. 552(b)(4) or which would be considered as such if it had been obtained from a non- Federal party. Prior to the First Commercial Sale, Licensee agrees to provide PHS reasonable quantities of Licensed Products or materials made through the Licensed Processes for PHS research use and/or for PHS use in conducting pre- clinical, Phase I, Phase II, Phase m Clinical Trials. 5.02 Licensee agrees that products used or sold in the United States embodying Licensed Products or produced through use of Licensed Processes shall be manufactured in the United States, unless a written waiver is obtained in advance from PHS. 7 5.03 Licensee agrees, after First Commercial Sale, to make reasonable quantities of Licensed Products or materials produced through the use of Licensed Processes available on a compassionate use basis to patients, either through the patient's physician(s) and/or the medical center treating the patient. 5.04 Licensee agrees, after First Commercial Sale and as part of their marketing and product promotion, to develop written educational materials (e.g., brochures, advertisements, etc.) directed to patients and physicians detailing the Licensed Products and/or medical aspects and the therapeutic treatment(s) of ovarian carcinomas and mesotheliomas. 5.05 Licensee acknowledge that PHS may enter into future Cooperative Research and Development Agreements (CRADAs) under the Federal Technology Transfer Act of 1986 that relate to the subject matter of this Agreement. Licensee agrees not to unreasonably deny requests for a Research License from such future collaborators with PHS when acquiring such rights is necessary in order to make a Cooperative Research and Development Agreement (CRADA) project feasible. Licensee may request an opportunity to join as a party to the proposed Cooperative Research and Development Agreement (CRADA). 5.06 (a) In addition to the reserved license of Paragraph 5.01 above, PHS reserves the right to grant nonexclusive Research License directly or to require Licensee to grant nonexclusive Research License on reasonable terms. The purpose of this Research License is to encourage basic research, whether conducted at an academic or corporate facility. In order to safeguard the Licensed Patent Rights, however, PHS shall consult with Licensee before granting to commercial entities a Research License or providing to them research samples of materials made through the Licensed Processes. b) In exceptional circumstances, and in the event that Licensed Patent Rights are Subject Inventions made under a Cooperative Research and Development Agreement (CRADA), the Government, pursuant to 15 U.S.C. 3710a(b)(1)(B), retains the right to require the Licensee to grant to a responsible applicant a nonexclusive, partially exclusive, or exclusive sublicensee to use Licensed Patent Rights in Licensee's field of use on terms that are reasonable under the circumstances; or if Licensee fails to grant such a license, the Government retains the right to grant the license itself. The exercise of such rights by the Government shall only be in exceptional circumstances and only if the Government determines (1) the action is necessary to meet health or safety needs that are not reasonably satisfied by Licensee, (ii) the action is necessary to meet requirements for public use specified by Federal regulations, and such requirements are not reasonably satisfied by the Licensee; or (iii) the Licensee has failed to comply with an agreement containing provisions described in 15 U.S.C. 3710a(c)(4)(B). The determination made by the Government under this 8 Article is subject to administrative appeal and judicial review under 35 U.S.C. 203(2). 6.

The minimum annual royalty is due and payable on January 1 of each calendar year and may be credited against any earned royalties due for sales made in that year. The minimum annual royalty due for the first calendar year of this Agreement may be prorated according to the fraction of the calendar year remaining between the effective date of this Agreement and the next subsequent January 1. 6.03 Licensee agrees to pay PHS earned royalties as set forth in Appendix C. 6.04 Licensee agrees to pay PHS benchmark royalties as set forth in Appendix C. 6.05 Licensee agrees to pay PHS sublicensing royalties as set forth in Appendix C. 6.06 A patent or patent application licensed under this Agreement shall cease to fall within the Licensed Patent Rights and/or Background Patent Rights for the purpose of computing earned royally payments in any given country on the earliest of the dates that a) the application has been abandoned and not continued, b) the patent expires or irrevocably lapses, or c) the claim has been held to be invalid or unenforceable by an unappealed or unappealable decision of a court of competent jurisdiction or administrative agency. 6.07 No multiple royalties shall be payable because any Licensed Products or Licensed Processes are covered by more than one of the Licensed Patent Rights and Background Patent Rights. 6.08 (a) Transfer of Licensed Products by Licensee to sublicensees or an Affiliated party made in other than an arm's-length for no furler resale shall be attributed a value which would have been recovered in an arm's length transaction of like quantity and quality of products sold on or about the time of the transfer of Licensed Products for the purpose of calculating Net Sales. 6.08 (b) Transfer of Licensed Products by Licensee to sublicensees or Affiliated party for furler resale shalt have attributed either a value which would have been received in an arm's- length transaction based on sales or like 9 quantity and quality of products transferred on or about the time of each transfer of Licensed Products or the actual value received in a later arm's length transaction, whichever is greater, for purposes of calculating Net Sales. 6.09 With regard to expenses associated with the preparation, filing, prosecution, and maintenance of all patent applications and patents included within the Licensed Patent Rights and Background Patent Rights incurred by PHS prior to the effective date of this Agreement, Licensee shall pay to PHS, as an additional royalty, within sixty (60) days of PHS's submission of a statement and request for payment to Licensee, an amount equivalent to such patent expenses previously incurred by PHS and detailed in Appendix G. 6.10 With regard to expenses associated with the preparation, filing, prosecution, and maintenance of all patent applications and patents included within the Licensed Patent Rights and Background Patent Rights incurred by PHS on or after the effective date of this Agreement, PHS, at its sole option, may require Licensee: (a) to pay PHS on an annual basis, within sixty (60) days of PHS's submission of a statement and request for payment, a royalty amount equivalent to all such patent expenses incurred during the previous calendar year(s); or (b) to pay such expenses directly to the law firm employed by PHS to handle such functions. However, in such event, PHS and not Licensee shall be the client of such law firm. In limited circumstances, Licensee may be given the right to assume responsibility for the preparation, filing, prosecution, or maintenance of any patent application or patent included with the Licensed Patent Rights. In that event, Licensee shall directly pay the attorneys or agents engaged to prepare, file, prosecute, or maintain such patent applications or patents and shall provide to PHS copies of each invoice associated with such services as well as documentation that such invoices have been paid. 6.11 Licensee may elect to surrender its rights in any country of the Licensed Territory under any Licensed Patent Rights and Background Patent Rights upon ninety (90) days written notice to PHS and owe no payment obligation under Article 6.10 for patent-related expenses incurred in that country after ninety (90) days of the effective date of such written notice. 7. PATENT FILING, PROSECUTION, AND MAINTENANCE 7.01 Except as otherwise provided in this Article 7, PHS agrees to take responsibility for, but to consult with, the Licensee in the preparation, filing, prosecution, and maintenance of any and all patent applications or patents included in the Licensed 10 Patent Rights and shall furnish copies of relevant patent-related documents to Licensee. 7.02 Upon PHS's written request, Licensee shall assume the responsibility for the preparation, filing, prosecution, end maintenance of any and all patent applications or patents included in the Licensed Patent Rights and shall on an ongoing basis promptly furnish copies of all patent-related documents to PHS. In such event, Licensee shall, subject to the prior Approval of PHS, select registered patent attorneys or patent agents to provide such services on behalf of Licensee and PHS. PHS shall provide appropriate powers of attorney and other documents necessary to undertake such actions to the patent attorneys or patent agents providing such services. Licensee and its attorneys or agents shall consort with PHS in all aspects of the preparation, filing, prosecution and maintenance of patent applications and patents included within the Licensed Patent Rights and shall provide PHS sufficient opportunity to comment on any document that Licensee intends to file or to cause to be filed with the relevant intellectual property or patent office. 7.03 At any time, PHS may provide Licensee with written notice that PHS wishes to assume control of the preparation, filing, prosecution, and maintenance of any and all patent applications or patents included in the Licensed Patent Rights. If PHS elects to assume such responsibilities, Licensee agrees to cooperate fully with PHS, its attorneys, and agents in the preparation, filing, prosecution, and maintenance of any and all patent applications or patents included in the Licensed Patent Rights and to provide PHS with complete copies of any and all documents or other materials that PHS deems necessary to undertake such responsibilities. Licensee shall be responsible for all costs associated with transferring patent prosecution responsibilities to an attorney or agent of PHS's choice. 7 04 Each park shall promptly inform the other as to all matters that come to its attention that may affect the preparation, filing, prosecution, or maintenance of the Licensed Patent Rights and permit each other to provide comments and suggestions with respect to the preparation, filing, prosecution, and maintenance of Licensed Patent Rights, which comments and suggestions shall be considered by the other party. 8. RECORDKEEPING 8.01 Licensee agrees to keep accurate and correct records of Licensed Products made, used, sold, or imported and Licensed Processes practiced under this Agreement appropriate to determine the amount of royalties due PHS. Such records shall be retained for at least five (5) years following a given reporting period and shall be available during normal business hours for inspection at the expense of PHS by an accountant or other designated auditor selected by PHS for the sole purpose of verifying reports and payments hereunder. The accountant or auditor shall only 11 disclose to PHS information relating to the accuracy of reports and payments made under this Agreement. If an inspection shows an under reporting or underpayment in excess of five percent (5%/0) for any twelve (12) month period, then Licensee shall reimburse PHS for the cost of the inspection at the time Licensee pays the unreported royalties, including any late charges as required by Paragraph 9.08 of this Agreement. All payments required under this Paragraph shall be due within thirty (30) days of the date PHS provides Licensee notice of the payment due. 8.02 Licensee agrees to have an audit of sales end royalties conducted by an independent auditor at least every two (2) years if annual sales of the Licensed Product or Licensed Processes are over two (2) million dollars. The audit shall address, at a minimum, the amount of gross sales by or on behalf of Licensee during the audit period, terms of the license as to percentage or fixed royalty to be remitted to the Government, the amount of royalty funds owed to the Government under this Agreement, and whether the royalty amount owed has been paid to the Government and is reflected in the records of the Licensee. The audit shall also indicate the PHS license number, product, and the time period being audited. A report certified by the auditor shall be submitted promptly by the auditor directly to PHS on completion. Licensee shall pay for the entire cost of the audit. 9. REPORTS ON PROGRESS BENCHMARKS, SALES AND PAYMENTS 9.01 Prior to signing this Agreement, Licensee has provided to PHS the Commercial Development Plan at Appendix F, under which Licensee intends to bring the subject matter of the Licensed Patent Rights and/or Background Patent Rights to the point of Practical Application. This Commercial Development Plan is hereby incorporated by reference into this Agreement. Based on this plan, performance Benchmarks are determined as specified in Appendix E. 9.02 Licensee shall provide written annual reports on its product development progress or efforts to commercialize under the Commercial Development Plan for each of the Licensed Fields of Use within sixty (60) days after December 31 of each calendar year. These progress reports shall include, but not be limited to: progress on research and development, status of applications for regulatory approvals, manufacturing, sublicensing, marketing, importing, and sales during the preceding calendar year, as well as plans far the present calendar year. PHS also encourages these reports to include information on any of Licensee's public service activities that relate to the Licensed Patent Rights and Background Patent Rights. If reported progress differs from that projected in the Commercial Development Plan and Benchmarks, Licensee shall explain the reasons for such differences. In any such annual report, Licensee may propose amendments to the Commercial Development Plan, acceptance of which by PHS may not be denied unreasonably. Licensee agrees to provide any additional information reasonably required by PHS to evaluate Licensee's performance under this Agreement. Licensee may 12 amend the Benchmark at any time upon written consent by PHS. PHS shall not unreasonably withhold approval of any request of Licensee to extend the time periods of this schedule if such request is supported by a reasonable showing by Licensee of diligence in its performance under the Commercial Development Plan and toward bringing the Licensed Products to the point of Practical Application as defined in 37 CFR 404.3(d). Licensee shall amend the Commercial Development Plan and Benchmarks at the request of PHS to address any Licensed fields of Use not specifically addressed in the plan originally submitted. 9.03 Licensee shall report to PHS the dates for achieving Benchmarks specified in Appendix E and the First Commercial Sale in each country in the Incensed Territory within thirty (30) days of such occurrences. 9.04 Licensee shall submit to PHS within sixty (60) days after each calendar half-year ending June 30 and December 31 a royalty report setting forth for the preceding half-year period the amount of the Licensed Products sold or Licensed Processes practiced by or on behalf of Licensee in each country within the Licensed Territory, the Net Sales, and the amount of royalty accordingly due. With each such royalty report, Licensee shall submit payment of the earned royalties due. If no earned royalties are due to PHS for any reporting period, the written report shall so state. The royalty report shall be recorded as correct by an authorized officer of Licensee and shall include a detailed listing of all deductions made under Paragraph 2.10 to determine Net Sales made under Article 6 to determine royalties due. 9.05 Licensee agrees to forward semi-annually to PHS a copy of such reports received by Licensee from its sublicensees during the preceding half-year period as shall be pertinent to a royalty accounting to PHS by Licensee for activities under the sublicensee. 9.06 Royalties due under Article 6 shall be paid in U.S. dollars. For conversion of foreign currency to U.S. dollars, the conversion rate shall be the New York foreign exchange rate quoted in THE WALL STREET JOURNAL on the day that the payment is due. All checks and bank drafts shall be drawn on United States banks and shall be payable, as appropriate, to "NIH/Patent Licensing." All such payments shall be sent to the following address: NIH, P.O. Box 360120, Pittsburgh, PA 15251-6120. Any loss of exchange, value, taxes, or other expenses incurred in the transfer or conversion to U.S. dollars shall be paid entirely by Licensee. The royalty report required by Paragraph 9.04 of this Agreement shall accompany each such payment, and a copy of such report shall also be mailed to PHS at its address for notices indicated on the Signature Page of this Agreement. 13 9.07 Licensee shall be solely responsible for determining if any tax on royalty income is owed outside the United States and shall pay any such tax and be responsible for all filings with appropriate agencies of foreign governments. 9.08 Interest and penalties may be assessed by PHS on any overdue payments in accordance with the Federal Debt Collection Act. The payment of such late charges shall not prevent PHS from exercising any other rights it may have as a consequence of the lateness of any payment. 9.09 All plans and reports required by this Article 9 and marked "confidential" by Licensee shall, to the extent permitted by law, be treated by PHS as commercial and financial information obtained from a person and as privileged and confidential, and any proposed disclosure of such records by the PHS under the Freedom of Information Act (FOIA), 5 U.S.C. Section 552 shall be subject to the predisclosure notification requirements of 45 CFR Section 5.65(d). 10. PERFORMANCE 10.01 Licensee shall use its reasonable best efforts to bring the Licensed Products and Licensed Processes to Practical Application. "Reasonable best efforts" for the purposes of this provision shall include adherence to the Commercial Development Plan at Appendix F and performance of the Benchmarks at Appendix E. The efforts of a sublicensee shall be considered the efforts of Licensee. 10.02 Upon the First Commercial Sale, until the expiration of this Agreement, Licensee shall use its reasonable best efforts to make Licensed Products and Licensed Processes reasonably accessible to the United States public. 11. INFRINGEMENT AND PATENT ENFORCEMENT 11.01 PHS and Licensee agree to notify each other promptly of each infringement or possible infringement of the Licensed Patent Rights and for Background Patent Rights, as well as any facts which may affect the validity, scope, or enforceability of the Licensed Patent Rights and/or Background Patent Rights of which either Party becomes aware. 11.02 Pursuant to this Agreement and the provisions of Chapter 29 of title 35, United States Code, Licensee may: a) bring suit in its own name, at its own expense, and on its own behalf for infringement of presumably valid claims in the Licensed Patent Rights; b) in any such suit, enjoin infringement and collect for its use, damages, profits, and awards of whatever nature recoverable for such infringement; and c) settle any claim or suit for infringement of the Licensed Patent Rights provided, however, that PHS and appropriate Government authorities shall have the first right to take such actions. If Licensee desires to 14 initiate a suit for patent infringement, Licensee shall notify PHS in writing. If PHS does not notify Licensee of its intent to pursue legal action within ninety (90) days, Licensee will be free to initiate suit. PHS shall have a continuing right to intervene in such suit. Licensee shall take no action to compel the Government either to initiate or to join in any such suit for patent infringement. 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 costs incurred by the Government in opposing any such motion or other action. In all cases, Licensee agrees to keep PHS reasonably appraised of the status and progress of any litigation.
