WITNESSETH

WHEREAS, VICAL has certain Patent Rights as defined below and wishes to grant to Licensee, and Licensee wishes to obtain from VICAL, an exclusive license to such Patent Rights for use in Hepatocyte Growth Factor (“HGF”) gene therapy applications in accordance with the terms of this Agreement.

NOW THEREFORE, the parties agree as follows:

ARTICLE I — DEFINITIONS

1.1 Patent Rights shall mean the patents listed in Exhibit A, attached hereto and incorporated herein by reference and all foreign and domestic applications and patents derived therefrom, including all continuations, continuations-in-part, division, reexaminations, reissues, substitutions, renewals, extensions, supplementary protection certificates and all patents granted thereon, which claim priority to any of the patents listed in Exhibit A. Patent Rights shall also mean patent applications existing as of the Effective Date that read to the Licensed Field, and will be added from time to time to Exhibit A when such patents issue.

1.2 Licensed Products shall mean and include any and all products the making, using, selling or importing of which would, but for the license granted in this Agreement, constitute an infringement of one or more Valid Claims of the Patent Rights.

1.3 Valid Claim shall mean any claim in an unexpired patent included within Patent Rights which claim has not been disclaimed or held invalid or unenforceable by an unappealed or unappealable decision of a court.

1.4 Licensed Field shall mean the manufacture, use and/or sale of the Licensed Products using the HGF Gene.

1

1.5 Licensed Territory shall mean any country in which the making, using, selling or importing of Licensed Products would, but for the license granted in this Agreement, infringe one or more Valid Claims of the Patent Rights.

1.6 Net Sales shall mean the gross amount invoiced by Licensee or its Affiliates or its Partners from the sales of Licensed Products within the Licensed Field in the Licensed Territory to third party customers less:

a) cash, quantity and trade discounts actually allowed;

b) credits allowed for returned or damaged goods;

c) transportation costs, including insurance; and

d) sales, excise, value added, import and export taxes, and any tariffs and duties imposed on the transaction, if separately invoiced.

In the case of any sale of Licensed Products between or among Licensee and its Affiliates or Partners for resale, Net Sales shall be calculated as above only on the value charged or invoiced on the first arm’s length sale thereafter to a third party customer. In the case of any sale of Licensed Products between or among Licensee and its Affiliates or Partners where Licensee or its Affiliate or Partner is the end user of such Licensed Product, Net Sales shall be calculated as above on the value that would be charged or invoiced to a third party end user in an arm’s length sale.

1.7 Earned Royalties shall mean royalties paid or payable by Licensee to VICAL as determined with respect to Net Sales.

1.8 Affiliate means any corporation or other business entity in which Licensee owns or controls, directly or indirectly, at least fifty percent (50%) of the outstanding stock or other voting rights entitled to elect directors, or in which Licensee is owned or controlled directly or indirectly by at least fifty percent (50%) of the outstanding stock or other voting rights entitled to elect directors.

1.9 Partner means any third party company or legal entity which is not an Affiliate of Licensee, with which Licensee has a joint venture or collaboration or marketing/distribution or such other arrangement providing the third party company or entity the right to co-manufacture, co-develop, co-promote or co-market Licensed Products in the Licensed Field in conjunction with Licensee.

1.10 HGF Gene shall mean DNA sequences corresponding to the mRNA sequence defined by Genbank Accession number NM_000601 encoding human HGF (known variously as hepatocyte

2

growth factor, hepapoietin A, and scatter factor) which when expressed affords the human HGF protein or any isoform or therapeutically active truncation thereof.

1.11 IHD means ischemic heart disease.

ARTICLE II — THE GRANT

2.1 VICAL hereby grants to Licensee and its Affiliates, subject to the terms and conditions hereof, an exclusive license under Patent Rights, to make, have made, use, import, sell, offer to sell and have sold the Licensed Products within the Licensed Field in the Licensed Territory. No license is granted outside the Licensed Field.

2.2 Licensee acknowledges that certain of the rights granted by VICAL to Licensee under this Article II are licensed to VICAL by the Wisconsin Alumni Research Foundation (“Licensor” or “WARF”), and such rights are subject to the applicable terms and conditions of the license agreement between VICAL and WARF (the “Licensor Agreement”), a redacted copy of which is attached as Exhibit B. In the event that the Licensor Agreement is terminated, the rights granted by VICAL to Licensee under this Article II, which are licensed to VICAL by Licensor under the Licensor Agreement, shall continue as a direct license from Licensor to Licensee on the terms set forth in the Licensor Agreement. Licensee acknowledges that such license provided directly from Licensor shall be limited in scope to that commensurate with the license granted under this Agreement. In such event, Licensee agrees to be bound by the terms of the Licensor Agreement (including royalty rates, product liability and other rights owing Licensor thereunder) as if Licensee were the licensee thereunder in the event of such termination.

2.3 Licensee may grant sublicenses under the license granted in Section 2.1 above only to Licensee’s Partners and only to the extent that said sublicense is limited to the Partner’s right to manufacture, use, sell and import Licensed Products within the Licensed Field in conjunction with Licensee. Within thirty (30) days of the execution of this Agreement, or in the case of Licensee’s new Partner Agreements, within thirty (30) days of the execution of the Partner Agreement, Licensee shall notify its Partner(s) that Licensee may grant to the Partner only limited rights under the Patent

3

Rights for the Licensed Field and that the Partner will need a separate license from VICAL for the Partner’s use, manufacture or sale of any additional products which are not made in conjunction with Licensee. Licensee shall be responsible to VICAL within the Licensed Field with respect to any actions or omissions of its Affiliates and Partners as if they were actions or omissions of Licensee. Licensee and its Affiliates may not grant any sublicense under the Patent Rights except as expressly provided in this Section 2.3.

2.4 Licensee agrees that it, including its Affiliates and Partners, will diligently pursue development and commercialization of Licensed Products. Licensee will provide to VICAL a written summary report summarizing Licensee’s and its Affiliates’ and Partners’ development and commercialization plans and activities with respect to Licensed Products on an annual basis by December 31 of each year.

3.1 In consideration of the rights granted to Licensee pursuant to Article II of this Agreement, Licensee agrees to make the following payments to VICAL:

One (1) Million dollars ($1,000,000) to be paid within thirty (30) days upon execution of this Agreement.

Each milestone payment shall be payable by Licensee within thirty (30) days of the date that the applicable milestone event with respect to PAD occurs to retain license rights.

In the event that Vical grants to any third party a license under the Patent Rights for commercial human therapeutic use within the field of Angiogenesis upon royalty rates more favorable to such third party than those set forth in Section 3.1(f), Licensee shall have the right to such more favorable royalty rates, provided Licensee also accepts any less favorable terms which may accompany the same (which may include, without limitation, additional license fees and/or milestone payments).

3.2 After launch of Licensed Product, Licensee agrees to submit to VICAL within sixty (60) days after December 31, March 31, June 30 and September 30 of each calendar year, reports setting forth for the preceding three (3) month reporting period, the Net Sales of Licensed Products and royalty due thereon and with each such royalty report to pay the amount of royalty due. Each such royalty report will cover Licensee’s most recently completed calendar quarter and will show:

3.3 If no sales of Licensed Products have been made during any reporting period, a statement to this effect is required.

3.4 Licensee shall, and shall cause its Affiliates and Partners to, keep complete, true and accurate books of account and records of Licensed Products made, used and/or sold under this Agreement for the purpose of showing the derivation of all amounts payable to VICAL under this Agreement. Said books and records shall be kept at Licensee’s (or its Affiliate’s or Partner’s) principal place of business for at least five (5) years following the end of a reporting period to which they pertain. VICAL is hereby granted by Licensee the right, upon reasonable written notice to Licensee, to retain an independent certified public accountant reasonably acceptable to Licensee and appropriately bound by confidentiality, to audit Licensee’s (or its Affiliate’s or Partner’s) records solely to verify sales of the Licensed Products. VICAL shall bear the fees and expenses of such audit, but if an error in royalties of more than five percent (5%) of the total royalties due for any year is discovered in any audit, then Licensee shall bear the fees and expenses of that audit.

3.5 All payments due hereunder shall be payable in United States dollars. With respect to sales of Licensed Products invoiced in a currency other than United States dollars, the Net Sales amounts and the amounts due to Vical hereunder shall be expressed in the domestic currency of the party making the sale together with the US dollar equivalent, calculated using the arithmetic average of the mid-range exchange rates for the last business day of each month of the reporting period in which the Net Sales were made. The “Key Currency Cross Rates” as reported in The Wall Street Journal or any other publication as mutually agreed by the parties shall be used as the source for the exchange rates to calculate the average as defined in the preceding sentence. All payments due under this Agreement shall be without deduction of exchange, collection or other charges or any withholding tax.

ARTICLE IV — TERM AND TERMINATION

4.1 Unless terminated earlier in accordance with this Agreement, the term of this Agreement shall be until the expiration of the last to expire of the Patent Rights or until the Patent Rights are held invalid or unenforceable by a court or tribunal from which no appeal can be taken.

4.2 In the event that Licensee shall become insolvent, shall make an assignment for the benefit of its creditors, or shall have a petition in bankruptcy filed for or against it and such petition shall not have been discharged within ninety (90) days, VICAL may, at its option, terminate this Agreement upon thirty (30) days written notice. In addition, VICAL may terminate this Agreement upon or after the breach by Licensee of any material provision of this Agreement if Licensee has not cured such breach within thirty (30) days after written notice thereof by VICAL.

4.3 Licensee shall have the right to terminate this Agreement at any time by written notice to VICAL to that effect. Licensee shall have the right during a period of six (6) months following the effective date of such termination to sell or otherwise dispose of the Licensed Products existing at the time of such termination, and shall make a final report and payment of all royalties related thereto within sixty (60) days following the end of such period or the date of the final disposition of such inventory, whichever first occurs.
