Patents and Improvements

3.1 Patent Applications.

3.2 Patent Prosecution. Licensor further agrees to use its best efforts to prosecute such patent applications and to maintain any patents issued thereon. Notwithstanding the foregoing sentence, in the event that Licensor within its sole judgment and discretion determines that prosecution or maintenance of a patent in a particular country is not economically viable or otherwise feasible, Licensor shall promptly notify Licensee of Licensor’s intention to abandon such patent application or patent. Licensor shall not otherwise abandon a patent or patent application within the Patent Rights. Upon receipt of such notice, Licensee, in its sole discretion, may elect to assume responsibility (and to pay associated fees and expenses generated after Licensee assumes such responsibility) with respect to a patent application or patent which Licensor intends to

abandon. The notice shall be provided sufficiently in advance of any deadlines or due dates such that Licensee has a reasonable time within which to assume responsibility and comply with the deadlines or due dates.

3.3 Licensor Improvements. Licensor agrees to make available promptly to Licensee during the term of this Agreement any Improvements now or hereafter found, owned, or controlled by Licensor, and to submit to Licensee all available Know-How pertaining thereto.

Any Improvements, whether patentable, copyrightable or not, now or hereafter made and found by agents or employees of Licensee either independently of agents or employees of Licensor (or an “Other Corporation”), or jointly with others, shall be owned by Licensor and shall be considered as part of the Licensed Proprietary Property. The world-wide rights in the corresponding patents, patent applications, copyrights

and/or know-how shall be the property of Licensor subject to all the terms and conditions of this Agreement, but licensed hereunder to Licensee by Licensor. Licensee agrees to do all things necessary and required to vest in Licensor all right, title and interest in and to any such Improvements.

3.6 Assistance. If patentable or otherwise protectable Improvements are now or hereafter made and found by agents or employees of Licensee or Licensor, either independently or jointly with others, and Licensor or Licensee considers it desirable to obtain patent, copyright or other protection thereon, the other party agrees to cooperate fully and to do all proper things necessary or desirable to obtain and maintain patent, copyright or other protection therefor throughout the world.

ARTICLE IV

Royalties and Other Consideration

4.1 License Fee. Upon Licensee’s execution of this Agreement, Licensee shall pay Licensor an up-front non-refundable license fee consisting of Four Hundred and Ten Thousand Dollars ($410,000) payable in shares of and by transferring to Licensor shares of the common stock of SuperGen, Inc. Licensee guarantees, as described herein, the value of such shares to be no less than such dollar amount (the “Guaranteed Value”) on the one (1) year anniversary of the date on which the shares are transferred to Licensor (hereafter the “Anniversary Date”). If, during the thirty (30) days preceding the Anniversary Date (or the next trading date if the Anniversary Date is not a trading date), the common stock of Licensee has not traded on a public stock exchange for an average price resulting in such shares being worth on average at least the Guaranteed Value, then within thirty (30) days Licensee will pay to Licensor a sum in cash (or, at Licensor’s option, in the equivalent value of additional unrestricted shares of the common stock of SuperGen, Inc.) equal to the difference between (a) the Guaranteed Value and (b) the average price at which the common stock of SuperGen, Inc. traded publicly during the thirty (30) days preceding the Anniversary Date multiplied by the number of shares transferred as the up-front non-refundable license fee under this Section 4.1. Any shares provided to Licensor will not be sold for at least one (1) year following the Anniversary Date, and no more than three thousand (3,000) of the shares shall be sold on any one trading date.

4.2 Royalty. Licensee shall pay Licensor during the term of this Agreement an earned royalty of six and one-half percent (6.5%) on Gross Revenues. Only one (1) royalty shall be payable on a Product, regardless of the number of licensed applications and licensed patents of the Licensed Proprietary Property under which such Product has been manufactured, used or sold. In the event that a Product is sold in combination as a single product with another product (“Combination Product”), active component or service (which product, component or service is not a portion of the Product) and whose sale and use are not covered by a Valid Claim of the Product in the country for which the combination product is sold, Gross Revenues from such sales for purposes of calculating the amounts due under this Agreement shall be calculated by multiplying the Gross Revenues of that combination by the fraction A/(A+B), where A is the gross selling price of the Product sold separately and B is the gross selling price of the other product, active component or service sold separately. In the event that no such separate sales are made by Licensee or its Sublicensee, Gross Revenues for royalty determination shall be reasonably allocated between the Product and such other product, active component or service, based upon their relative importance and proprietary protection. Without limitation, liposomal compounds, paclitaxel and analogues thereof, and aerosol containers (nebulizers) are deemed to be portions of the Product.

4.3 Term of Royalty Obligation. Royalty payments shall be paid on the Products commencing on the Effective Date, and unless earlier terminated as provided herein, shall continue on a country-by-country and Product-by-Product basis until there are no remaining royalty payment obligations in a country, at which time the Agreement shall expire in its entirety in such country. Royalty payments shall cease for any patent which has been declared invalid or unenforceable by a

final determination or judgment, or if this Agreement is terminated as hereinafter specified and provided.

4.4 Sublicenses. Licensee will pay to Licensor fifty percent (50%) of all consideration (including, but not limited to, royalties, minimum royalties, up-front payments, marketing, distribution, franchise, option, license or documentation fees, bonus and milestone payments, license maintenance fees, and equity-related securities) received from sublicensees of the Licensed Proprietary Property or the amount of royalty Licensee would have owed pursuant to Section 4.2 had it engaged in the same licensed conduct as said sublicensees, whichever is greater, as determined on a quarterly basis. Notwithstanding the above, it is understood and agreed that Licensor shall not be entitled to any share of amounts received by Licensee for pilot studies, research and development, the license or sublicense of any intellectual property other than the Licensed Proprietary Property, reimbursement for patent or other expenses, or as consideration for equity or debt of Licensee.

4.5 Deductions From Royalty Payments; Limitation on Deductions from Royalty Payments. If Licensee or its Sublicensee is required to pay a third party under a Valid Claim with respect to the third party’s intellectual property or technology in order to make, use or sell a Product, Licensee may deduct such amount from royalties due to Licensor for such Product. Notwithstanding the foregoing provisions of this Section 4.5, wherever this Agreement provides that Licensee may deduct expenses, payments or other amounts from royalties payable to Licensor, (a) such deduction shall be applied only against royalties payable from the territory with respect to which such deduction arose, and (b) such deduction shall be prorated over such time as is necessary

to assure that the royalties payable to Licensor from such territory in any period shall not be reduced by more than fifty percent (50%) of the amount that otherwise would be due Licensor pursuant to this Agreement.

4.6 Milestone Payments. In addition to the up-front license fee and royalties required under this Article IV, Licensee shall make milestone payments to Licensor as set forth in Exhibit 3 hereto. Such payments shall be made in common stock of Licensee in the amounts recited in Exhibit 3 and shall be transferred to Licensor within thirty (30) days of occurrence of each of the events indicated on such exhibit. Such common stock will not be sold for at least one (1) year following the date on which the stock is transferred to Licensor, and no more than three thousand (3,000) of the shares shall be sold on any one trading date. Licensee guarantees the value of such shares to be the Guaranteed Value calculated in the same manner as set forth in Section 4.1 of this Agreement.

4.7 Marketing Arrangements. Where Products are marketed by an entity other than Licensee under any type of commercial arrangement (including, without limitation, a sublicense, joint venture, distributorship, or collaboration agreement), the sales of the Products by such entity shall be used in calculating Gross Revenues for purposes of determining royalties payable to Licensor hereunder.

4.8 Conditions. The obligations of Licensee under this License Agreement are conditioned on Licensee’s satisfaction in its sole discretion at or prior to the date this License Agreement is executed with the results of its due diligence with respect to the business, operations, affairs, properties, assets, liabilities, obligations, profits and condition (financial or otherwise) of

Licensor; provided that compliance with any such conditions or parts thereof may be waived in writing by Licensee. Licensor agrees to provide Licensee with any information, including clinical or laboratory data or regulatory filings, that Licensor requests as part of the due diligence performed under this Section 4.8.

ARTICLE V

Payment and Reports

5.1 Notice of Commercial Sale. Licensee shall notify Licensor, in writing, within thirty (30) days of the date of the first commercial making, using or selling of Products.

5.2 Payments and Reports. Licensee agrees that Licensee shall provide within sixty (60) days after the end of each quarter of each calendar year:

(a) payment of amounts due to Licensor pursuant to this Agreement, including, but not limited to, amounts pursuant to Articles IV and VI; and

(b) a report summarizing the information and basis on which such amounts have been calculated.

5.3 U.S. Dollars. All amounts payable in cash by Licensee shall be paid in U.S. Dollars. Conversion from currencies other than U.S. Dollars shall be at the rate of exchange used by Licensee for its general accounting purposes, consistent with generally accepted accounting principles.

5.4 Progress Reports. Until such time as earned royalties become payable pursuant to this Agreement, Licensee agrees to make an annual report to Licensor on each annual anniversary

of the Effective Date covering Licensee’s progress during the previous year toward research, development and commercialization.

5.5 Report on Termination. Licensee also agrees to make a written report to Licensor within ninety (90) days after the termination of this Agreement, stating in such report the royalties payable hereunder and the basis therefor not previously reported to Licensor. Licensee shall also continue to make annual reports pursuant to the provisions of this Agreement covering making, using or selling of Products after termination thereof, such as the selling of stock on hand at termination which is specifically contemplated by this Agreement and the applicable earned royalties hereunder, until such time as all such makings, uses or sales shall have terminated. Concurrent with the submittal of each post-termination report, Licensee shall pay Licensor all applicable royalties.

5.6 Books and Records. Licensee shall keep accurate books and records with respect to the Products and/or Licensed Proprietary Property sufficient to enable the calculation of royalties payable hereunder to be verified. Upon thirty (30) days prior notice to Licensee, independent accountants selected by Licensor, reasonably acceptable to Licensee, after entering into a confidentiality agreement with Licensee, may have access to the books and records of Licensee to conduct a review or audit once per calendar year, for the sole purpose of verifying the accuracy of Licensee’s payments and compliance with this Agreement. The accounting firm shall report to Licensor only whether there has been a royalty underpayment and, if so, the amount thereof. Such access shall be permitted during Licensee’s normal business hours during the term of this Agreement and for three (3) years after the period to which the audit pertains. Any such inspection

or audit shall be at Licensor’s expense; provided that in the event the examination or audit results in a discrepancy in the correctness of the payments due under this Agreement in an amount in excess of five percent (5%) of the payments due Licensor for any single quarter audited, Licensee shall pay any and all costs or fees associated with such examination or audit. Neither such right to review or audit nor Licensor’s right to receive any such underpayment shall be affected by any statement to the contrary appearing on checks or otherwise, unless such statements appear in a letter, signed by the party having such right and delivered to the other party, expressly waiving such right. Notwithstanding the foregoing, Licensor may require Licensee to furnish any other information reasonably requested to enable Licensor to evaluate Licensee’s performance under this Agreement.

5.7 Delinquent Payments. Payments provided for in this Agreement shall, when overdue, bear interest at the then existing prime rate at Citibank of New York (or its successor) plus four percent (4%) per annum until paid, but in no event shall such interest exceed the usury limit, if any, as may exist from time to time in the State of Nevada.

ARTICLE VI

Effort to Commercialize

6.1 Commercialization Obligation. Licensee shall undertake to use commercially reasonable efforts with regard to commercialization of the Products.

6.2 Minimum Royalties. Licensee shall pay to Licensor within ninety (90) days after the date specified at least the following amounts of minimum royalties within the time periods specified:

(a) on or before the third anniversary of the Effective Date, at least Twenty-Five Thousand Dollars ($25,000.00).

(b) on or before the fourth anniversary of the Effective Date, at least Twenty-Five Thousand Dollars ($25,000.00).

(d) on or before each succeeding anniversary of the Effective Date, at least Seventy-Five Thousand Dollars ($75,000.00).

Minimum royalties paid in excess of earned royalties in a given year shall not be creditable to earned royalties for future years. Minimum royalties paid under this Section 6.2 may, at Licensee’s option, be paid in shares of the common stock of Licensee. Common stock transferred under this Section 6.2 will not be sold for at least one (1) year following the date on which the stock is transferred to Licensor, and no more than three thousand (3,000) of the shares shall be sold on any one trading date. Licensee guarantees the value of such shares to be the Guaranteed Value calculated in the same manner as set forth in Section 4.1 of this Agreement.

ARTICLE VII

Protection of Patents

7.1 Protection. Licensor agrees, where economically justified and within reasonable limits, to protect the Licensed Proprietary Property from infringement or misappropriation by third parties in the Field of Use and to prosecute such infringers or defendants, but the decision to undertake such protection shall be in the sole discretion of Licensor, and Licensor’s decision as to whether any such action shall be taken by it shall be accepted by Licensee. In the event that Licensor shall recover profits and/or damages from said infringer or defendant in the Field of Use, Licensor agrees to turn over to Licensee twenty-five percent (25%) of any amounts paid to it by said infringer or defendant after deducting any of its expenses, including costs and legal fees incurred in such litigation. Each party agrees to cooperate fully with the other party in protection of the Licensed Proprietary Property, including by joining as a party to any proceeding if required by applicable law.

7.2 Notice of Infringement; Third Party Infringement. Licensor and Licensee shall each give immediate written notice to the other of any infringement of a Patent Right or misappropriation of Know-How or Improvements by any third party in the Field of Use as may come to its knowledge. Notwithstanding Section 7.1, if Licensor has not within six (6) months from the date on which it is notified or otherwise becomes aware of an infringement or misappropriation of the Licensed Proprietary Property in the Field of Use either terminated such infringement or initiated legal action against the infringer or defendant, it shall, upon written request of Licensee, grant to Licensee the right to prosecute an action against the infringer or defendant at Licensee’s expense. Licensor agrees, in the event that Licensee cannot prosecute such infringement or misappropriation in its own name, to sign and give to Licensee, as soon as

practicable, all necessary documents in order for Licensee to prosecute at Licensee’s expense but in the name of Licensor, such infringement or misappropriation. Licensee shall be entitled to deduct all of its expenses, including costs and legal fees incurred in bringing and prosecuting such infringement or misappropriation action, from royalties due Licensor with respect to the country in which such action is prosecuted after commencement of such infringement or misappropriation action. In the event Licensee desires to settle or compromise such suit or action in a manner that may adversely impact Licensor or Licensed Proprietary Property, Licensee shall not so settle or compromise such suit or action without the prior written consent of Licensor. In the event Licensee shall recover profits and/or damages from said infringer or defendant, Licensee agrees to pay to Licensor twenty-five percent (25%) of any amounts paid to it by said infringer or defendant after deducting any of its expenses, including costs and legal fees incurred in such litigation.

7.3 Notice of Infringement; Claim of Licensee Infringement. Licensee shall promptly advise Licensor in writing of any notice or claim of any infringement and of the commencement against it of any suit or action for infringement of a third party patent made or brought against Licensee and based upon the use hereunder by Licensee of the Licensed Proprietary Property. Licensee shall have the right either to:

(a) request that Licensor enter into negotiations with such third party to obtain rights for Licensee under the third party patent; or

(b) request that Licensor defend such suit or action at Licensor’s expense.

7.4 Assistance. Licensor is neither obligated to enter into negotiations with such third party to obtain rights for Licensee under the third party patent nor obligated to defend such suit or

action. If Licensor, at its sole discretion, elects to enter into negotiations with such third party to obtain rights for Licensee under the third party patent or if Licensor, at its sole discretion, elects to undertake at its own expense the defense of any such suit or action to the extent that the alleged infringement is based upon such use hereunder of the Licensed Proprietary Property, Licensee shall render to Licensor all reasonable assistance that may be required by Licensor in the negotiations or in the defense of such suit or action. Licensor has the primary right to control the defense of any such suit or action by counsel of its own choice, and Licensee shall have the right, at its own expense, to be represented in any such suit or action in respect of which Licensee is a defendant by counsel of its own choice, subject to Licensor’s right of control. Notwithstanding the foregoing, if Licensor has not within ninety (90) days (or such lesser period of time as is necessary to avoid entry of a default judgment against Licensor or Licensee) from the date of receipt of a request from Licensee under Section 7.3 either entered into negotiations with such third party to obtain rights for Licensee under the third party patent or initiated legal action to defend such suit, it shall, upon written request of Licensee, grant to Licensee the right to enter such negotiations or defend such suit. Licensee shall be entitled to deduct all its expenses, including attorneys’ fees and specifically including costs and legal fees incurred in entering into such negotiations or defending such suit from royalties due Licensor after commencement of such action. Licensee shall not settle or compromise any such suit or action without the prior written consent of Licensor, which consent shall not be unreasonably withheld.

ARTICLE VIII

Disclaimer of Liability and/or Warranty

8.1 No Warranty. Nothing in this Agreement shall be construed as:

(a) a warranty or representation by Licensor as to the validity or scope of any Licensed Proprietary Property; or

(b) a warranty or representation that anything sold, used, produced or otherwise disposed of under any license granted in this Agreement is or will be free from infringement of patents, copyrights, and/or trademarks of third parties; or

8.2 No Damages. Licensor shall exercise reasonable care in verifying the accuracy of information provided under this Agreement but, subject to the provisions of the last sentence of Section 8.4, Licensor shall not be liable for any damages arising out of or resulting from any information made available hereunder or of the use thereof, nor shall it be liable to Licensee for consequential damages under any circumstances.

8.3 No Warranty of Quality or Usefulness. Licensor shall have no responsibility for the ability of Licensee to use such information, the quality or performance of any process or any product produced by Licensee with the aid of such information, or with respect to claims of third parties arising from Licensee’s use of such information.

8.4 Indemnification. Licensee shall assume all responsibility and liability for the sale, use, production, and/or commercialization of the Products, including, but not limited to, the safety,

effectiveness, and reliability of the process and/or products produced pursuant to this Agreement. Licensee further agrees to defend, indemnify, and hold Licensor, its trustees, directors, officers, employees, agents, representatives, successors, assigns, affiliated entities and controlled corporations (as defined herein) harmless from and against any and all liability, demands, damages, expenses and losses for death, personal injury, illness, or property damage, including the cost of defense against same, which may be asserted, or any claims which may be brought by third parties resulting from the sale, use, production, commercialization, or other disposition of the Licensed Proprietary Property or Products by Licensee. Licensee agrees that any sublicenses granted hereunder will include a similar indemnification provision for the benefit of Licensor. Licensee acknowledges that the Licensed Proprietary Property included herein is experimental and agrees to take all reasonable precautions to prevent death, personal injury, illness, and property damage. Licensor shall defend, indemnify, and hold Licensee and its directors, officers, employees and agents harmless as against any and all judgements, fees, expenses, liabilities, or other costs arising from or incidental to any product liability or other lawsuit, claim, demand or other action resulting from any claim, suit or proceeding brought by a third party against any of the foregoing entities, arising out of or in connection with any misrepresentation by Licensor with regard to, or in breach of, the representations and warranties set forth in Article X or to the extent due to the gross negligence or willful misconduct of Licensor.

8.5 Insurance. Licensee agrees to purchase and/or maintain insurance coverage sufficient, taking into account its other assets, to establish the ability of Licensee to honor the indemnity made herein, and Licensor shall be listed as an additional named insured on any such

insurance coverage. Licensee shall furnish evidence of its insurance coverage upon request of Licensor. For purposes of this agreement, the initial amount of insurance coverage required is in the face amount of Two Million Dollars ($2,000,000.00).

ARTICLE IX

Term and Termination

9.1 Term. The Term of this Agreement shall be for a period of ten (10) years extending from the first commercial revenue actually collected or for the life of the last to expire of the patents or patent applications of the Licensed Proprietary Property, whichever is earlier, unless sooner terminated as herein provided.

9.2 Termination for Cause; Insolvency. If Licensee shall determine that it intends to declare itself insolvent or file for bankruptcy or reorganization, it shall give immediate written notice to Licensor. Failure to give such notice shall cause immediate termination of this Agreement, and all rights of Licensee in the Licensed Proprietary Property shall automatically revert to Licensor. If Licensee shall become bankrupt or insolvent; if the business or any assets or property of Licensee shall be placed in the hands of a receiver, assignee or trustee, whether by the voluntary act of Licensee or otherwise; if Licensee institutes or suffers to be instituted any procedure in bankruptcy court for reorganization or rearrangement of its financial affairs; or if Licensee makes a general assignment for the benefit of creditors, this Agreement shall immediately terminate, and all rights of Licensee in the Licensed Proprietary Property shall automatically revert to Licensor. Upon occurrence of any of the foregoing events, Licensee shall give immediate written

notice thereof to Licensor.

9.3 Default. Upon any breach or default under this Agreement by Licensee, or upon any breach or default by Licensee under other legal agreements between Licensor and Licensee, Licensor may give written notice thereof to Licensee, and Licensee shall have thirty (30) days thereafter to cure such breach or default. If such breach or default is not so cured, Licensor may then in its sole discretion and option: (a) convert this exclusive License Agreement into a non-exclusive License Agreement, or (b) terminate this Agreement and the licenses granted by it, or (c) seek such other relief as may be provided by law in such circumstances by giving written notice thereof to Licensee.
