SECTION II. LICENSE.

1. License Grant. CSURF hereby grants Company the sole and exclusive, worldwide license to the Technology to develop, manufacture, use and sell Products. Such license shall continue for the longer of 15 years or the life of any and all Patent(s).

2. Sublicenses. The Company shall have the right to grant sublicenses of any rights granted to it under this License, provided that Company shall have received the prior approval of CSURF, which shall not be unreasonably withheld. CSURF’s consent shall not be required for sublicenses to Company Subsidiaries or for contract processing or manufacturing sublicenses entered into to facilitate the Company’s development or production of Products.

3. Performance Goals. The Company agrees to use its reasonable best efforts to achieve performance goals agreed upon by CSURF and the Company. The Company’s performance goals for the 1996 Calendar year are set forth on “Exhibit A” attached hereto. Performance goals will be determined by CSURF and the Company upon consultation with the Principal Investigator in the years following 1996. The performance goals shall be replaced by the Company’s payment of minimum royalties under Section III(3) once payments are first made pursuant to Section III(3)(b).

4. Receipt and Delivery of Technology. The Company acknowledges both the receipt of the information which presently constitutes the Technology and fact that neither CSURF nor Principal Investigator represent or promise that they will develop or acquire any additional information or rights that would fall within the definition of Technology. To the extent CSURF or Principal Investigator develop or acquire any such information or rights, CSURF agrees to promptly disclose same to the Company.

SECTION III. PAYMENT OBLIGATIONS.

1. Percentage Royalties. Company shall pay CSURF a royalty on Net Sales (gross sales minus sales tax, returns, discounts and freight, if any) of Product(s) in each country where Product(s) are protected by a Patent(s) equal to:

(i) 6% of the first $1 million in Net Sales;

(ii) 4% of Net Sales in excess of $1 million and up to and including $5 million; plus

(iii) 3% of Net Sales in excess of $5 million.

Percentage Royalties on Net Sales of Product(s) where Product(s) are not protected by Patent(s) shall be payable at one-half of the foregoing rates.

2. Sublicenses. In the event that the Company sublicenses the License granted in Section II(1), the Company shall remain obligated to the terms of this agreement. Company shall either require the sublicensee to pay the Percentage Royalties required by this Section III(1)

3

or, at the election of the Company in sublicenses that are not to Subsidiaries, the Company shall pay CSURF one third of the Percentage Royalties received by Company from such sublicenses. Company shall also pay CSURF one third of any upfront, milestone, benchmark or any other miscellaneous income received from a sublicensee.

3. Minimum Royalties. In consideration of the exclusive nature of the license grant contained in Section II, Company agrees to pay CSURF Minimum Royalties as follows:

(a) $10,000 per year beginning with a first payment on March 31, 1996 and continuing each year thereafter until such time as the Company receives U.S. Government approval permitting Commercialization of Products.

(b) $20,000 per year beginning in two equal $10,000 installments payable on January 31, and July 31, in each of the first two years after the Company receives U.S. Government approval permitting Commercialization of the Products; and,

(c) $50,000 per year thereafter in quarterly installments of $12,500 each payable on January 31, April 30, July 31, and October 31.

The Company shall be entitled to credit Minimum Royalties paid in any year against Percentage Royalties earned in the same year but not against Percentage Royalties earned in prior years or subsequent years.

4. Milestone Payments. The Company shall make the following Milestone Payments to CSURF:

(a) $10,000 within 30 days after the filing of a product license application.

(b) $20,000 within 30 days after receipt of premarket approval from the FDA permitting Commercialization of the Products within the United States.

The Company shall be entitled to credit Milestone Payments made as well as out-of-pocket expenses incurred by the Company in the prosecution of the Patent(s) against future Percentage Royalties but the amount of the credit that may be taken in any year shall be limited, in that year, to the 50% of the amount by which Percentage Royalties exceed Minimum Royalties in that year. For example, if $30,000 in Milestone Payments and Patent prosecution costs were incurred before year 2 and Percentage Royalties in year 2 exceeded Minimum Royalties paid in year 2 by the sum of $40,000, the Company would be entitled to credit only $20,000 of such amount as a credit to Milestone Payments and Patent prosecution costs in that year. The remaining $10,000 of Milestone Payments and unreimbursed Patent prosecution costs would be reimbursed in the same, fashion in future years.

5. Nonexclusive License Payments. At any time after the third anniversary of Commercialization, the Company may elect to convert this License from an exclusive license to a nonexclusive license by notifying CSURF in writing. In the event the license is converted to a nonexclusive license as provided in the preceding sentence, the Company’s obligation thereafter

4

to make minimum royalty and milestone payments shall terminate. If CSURF thereafter relicenses the Technology to any third party at a lower percentage royalty rate than that provided in this Agreement, CSURF shall notify the Company of the lower royalty rate and offer the Company the opportunity to thereafter pay such lower royalty rate in lieu of the rate it would otherwise be obligated to pay hereunder.

6. Accounting for Payments.

(a) Payments of Percentage Royalties shall be made on or before the last business day of January, April, July and October of each year for the sale of all Products sold during the preceding quarterly periods ending on the last days of December, March, June and September. Such payments shall be accompanied by a statement showing the sales of the Products by the Company to all parties, and such other particulars as are necessary or which may be reasonably requested by CSURF for an account of the royalties payable pursuant to this Agreement. Payment of the amount of royalties due shall accompany such statement.

(b) The Company shall keep complete and accurate records of the sales by the Company of Products. Within 60 days following the end of each quarter of a calendar year during which the royalties are due under this Agreement, the Company shall render to CSURF a written report setting forth the amount of royalties due and payable based on sales of Products during such quarter, and upon rendering such report, remit to CSURF the amount of royalties shown thereby to be due on sales of products.

(c) CSURF shall have the right for a period of five years after receiving any royalty report to appoint an independent certified public accountant who is acceptable to the Company who shall have access to the Company’s records during reasonable business hours for the purpose of verifying the royalties payable under this Agreement, but this right may not be exercised more than once in any calendar year, and the accountant shall disclose to CSURF only information relating solely to the accuracy of the royalty report and the royalty payments made in accordance with this Agreement. The failure of CSURF to request verification of any royalty report during said five year period shall be considered acceptance of the accuracy of such report and the Company shall have no obligation to maintain any records pertaining to such report beyond said five year period.

SECTION IV. REGULATORY AND PATENT RESPONSIBILITIES.

1. Regulatory Approvals. The Company agrees, at its own expense, to take reasonable steps to obtain regulatory approval from the FDA to manufacture, use and sell Product(s) within the United States. If at any time the Company ceases to use reasonable efforts to seek regulatory approval from the FDA, the Company shall notify CSURF in writing identifying the reasons the Company no longer seeks FDA approval and the Agreement shall terminate. However, if CSURF is successful in licensing the Technology to a third party, CSURF will pay to the Company 50% or any income (royalties, upfront payments, milestone, benchmark or other miscellaneous payments) received from such license in any given fiscal year, for the term of such license in consideration of the Company’s efforts and expenses incurred in

5

development and commercialization costs and in consideration of patent related expenses incurred by the Company in connection with the Technology.

2. Patent Prosecution.

(a) The Company shall upon written request from CSURF bear the reasonable costs and responsibility for the preparation, filing and prosecution of the United States Patent Applications under the Technology, but in no case beyond an appeal to and a decision by the United States Patent and Trademark Office Board of Appeals, unless the Company specifically agrees otherwise in writing. With respect to foreign patent applications, the procedure shall be as follows: foreign patent applications shall be filed by the Company on behalf of CSURF in such countries as selected by the Company. Such selection of countries is to be made in writing by the Company to CSURF within nine months after the filing date of any corresponding U.S. application, and the filing of such designated foreign patent application will be made, in CSURF’s name within one year after the filing date of the corresponding U.S. application. The Company will pay the reasonable costs of the preparation, filing and prosecution of such foreign applications and the maintenance of the resulting patents for so long as the Company remains a licensee under the patents. CSURF may file and prosecute applications and maintain the resulting foreign patents at its own expense in countries not selected by the Company. The Company having elected to file a foreign patent application, may advise CSURF without loss of any right granted by this Agreement that it does not wish to pursue further prosecution or maintenance in a particular country and the Company will have no further obligations for payment of any costs for patent prosecution or maintenance in the country. CSURF may then, if it so desires, continue such prosecution or maintenance at its expense. Such election by the Company to discontinue prosecution or maintenance in a particular country shall not prejudice the Company’s rights under this Agreement in other countries.

(b) Company will keep CSURF informed of all patent activity related to the Technology by sending CSURF copies of all Patent filings (U.S. and foreign) and Patent prosecution related information. Company will also notify and allow the Principal Investigator the opportunity to be involved in the decisions related to the Science of any Patent application or Patent prosecution related to the Technology.

(c) In the event that during the course of this Agreement, a patentable invention is made jointly by one or more members of the Company and one or more researchers at CSU, as determined by the laws of patent inventorship, title to any Patent or Patents maturing therefrom shall be held by CSURF.

(d) If CSURF files Patent applications or otherwise obtains rights which relate to the Technology, the Company shall have a right to an exclusive worldwide license under such Patent rights as are set forth in Section II(1) and the exclusive license granted to the Company under Section II(1) shall be extended to the expiration date of the last expired patent which issues in any particular country. If CSURF decides not to file a Patent application on any CSURF invention which relates to the Technology, CSURF will promptly notify the Company of the decision and disclose such invention to the Company. The Company will then, at its option, have the right to file Patent applications throughout the world and to have an exclusive license,

6

with a right to grant sublicenses, under such Patent rights as are set forth in Section II(1) and exclusive license granted to the Company under Section II(1) shall be extended through the expiration date of the last to expire patent which issues in any particular country.

(e) CSURF shall be the sole and exclusive owner of said Patent(s), subject to the terms of this Agreement.

3. Patent Enforcement.

(a) CSURF does not warrant that the Technology licensed hereunder shall not infringe any patents. However, CSURF is not presently aware of the existence of such patents owned by third parties.

(b) CSURF and Company agree to inform each other in the event that it becomes aware of any potential infringement of the Technology. CSURF shall then, at its expense, have the right to take appropriate action against any potential infringer. In the event that CSURF elects not to take action against the potential infringer, the Company may elect to do so at its expense, in either its own name or in CSURF’s name. In either event, CSURF and the Company agree to cooperate fully with any such proceedings. The Company may not, as part of settlement negotiations, offer or grant non-exclusive licenses without the written consent of CSURF, such consent shall not be unreasonably withheld. If the Company pursues litigation, it shall be entitled to offset the cost of litigation against 50% of the royalty payments coming due during the litigation. If the Company succeeds in obtaining a damage judgment in the litigation, it shall be entitled to recoup its costs of litigation, to the extent not previously recouped out of royalties, plus 2/3 of the remaining amount of the judgment, if any. The remainder of the judgment, if any, shall be paid to CSURF as payment, in full, of royalties withheld by the Company during the litigation. If neither party pursues litigation and there is no acceptable settlement, the Company shall be entitled to withhold royalties until a settlement is reached, but only after obtaining an opinion from patent counsel reasonably acceptable to both parties that the Patents have been infringed.

SECTION V. ASSISTANCE FROM DR. ORTON AND REPORTING.

1. Assistance from Dr. Orton. CSURF warrants, that at the time of the signing of this Agreement, Dr. Orton has agreed to provide reasonable assistance (as long as he is a CSU employee) to the Company, as reasonably requested by the Company, in evaluating or testing Product(s) prototypes. The Company agrees to pay Dr. Orton a reasonable amount for out-of-pocket expenses and time in excess of ten hours per month associated with Dr. Orton’s assistance.

2. Reporting Responsibilities. CSURF, through the Principal Investigator, will provide semi-annual written reports to the Company summarizing the progress of ongoing research conducted by Dr. Orton and CSU on the Technology and will otherwise keep the Company fully and promptly informed of all progress on the Technology. The Company will provide semi-annual written reports to CSURF which summarize the progress of the Company’s efforts to meet its Performance Goals and to complete development of the Product.
