ARTICLE 7
RECORDS; AUDIT

7.1 Record Retention. NK shall keep complete, accurate and correct records in sufficient detail to permit NeoPharm to confirm the accuracy of the calculation of Net Sales and Royalties provided for in this Agreement. Such records shall be retained for no less than a five (5) year period following the year in which any such payments were made hereunder.

7.2 Audit. NeoPharm and any Licensor shall each have the right for a period of five (5) years after receiving any report, statement or payment with respect to Net Sales or Royalties, to obtain, at its expense, from an accountant or auditor selected by NeoPharm and agreed by NK an audit of all relevant records of NK to verify such report, statement or payment. NK shall make its records available for inspection by such accountant or auditor during regular business hours at such place or places where such records are customarily kept, upon reasonable notice from

NeoPharm or any Licensor, to the extent reasonably necessary to verify the accuracy of the reports and payments. Neither NeoPharm nor any Licensor may exercise its inspection right more than once in any calendar year, nor more than once with respect to sales in any given period, unless a subsequent inspection reveals discrepancies which may have also occurred during such period.

If NeoPharm or its applicable Licensors do not notify NK of their intent to respond to the legal action within a reasonable time, NK will be free to do so. NK shall take no action to compel NeoPharm or its applicable Licensors either to initiate or to join in any such declaratory judgment action.

NK shall directly pay the attorneys or agents engaged to defend NeoPharm or its applicable Licensors in said action. If NK elects not to defend against such declaratory judgment action, NeoPharm or its applicable Licensors, at their option, may do so at their own expense. In all cases, NK agrees to keep NeoPharm and its applicable Licensors reasonably apprised of the status and progress of any litigation. Before NK commences an infringement action, NK shall notify NeoPharm and its applicable Licensors and give careful consideration to the views of NeoPharm and its applicable Licensors and to any potential effects of the litigation on the public health in deciding whether to bring suit.

If NK decides to initiate suit to enforce the Licensed Patent Rights, NK must notify NeoPharm in writing. NeoPharm or its applicable Licensors shall have a continuing right to intervene in such suit. NK will take no action to compel NeoPharm or any applicable Licensor to join in any such suit for patent infringement. If NeoPharm or any Licensor is made party to such a suit, NK agrees to reimburse them for any costs, expenses, or fees which they incur as a result of such suit, including any and all costs incurred by them in opposing joinder as a party to such suit. In all cases, NK agrees to keep NeoPharm and its Licensors (as applicable) reasonably apprised of the status and progress of any litigation. NK shall retain any damages or recoveries obtained from such action.

The Parties shall confer with each other and cooperate during the defense of any such action. NK shall assist and co-operate with NeoPharm in the defense of any such action where only NeoPharm is named and, if NeoPharm finds it necessary to have NK join as a party, NK shall execute all papers or perform such other acts as may reasonably be requested by NeoPharm.

(c) For purposes of this Article 10, an indemnified Party shall be deemed to include the officers, directors, employees, students, fellows, agents, representatives, attorneys and consultants, shareholders, and contractors of such Party and its Affiliates.

10.2 Indemnification Procedure. Promptly after an indemnified Party becomes aware of any actual or potential Claim hereunder, such Party shall promptly deliver written notice to the indemnifying Party stating the nature of the Claim; provided, however, that the failure to give such notification shall not affect the indemnification provided hereunder except to the extent the indemnifying Party is actually prejudiced as a result of such failure. The indemnified Party shall give the indemnifying Party such information with respect to the Claim as the indemnifying Party may from time to time reasonably request. NeoPharm or any Licensor shall have the first right to (a) bring suit in their own respective names, at their own expense, and on their own behalf for infringement of presumably Valid Claims in the Licensed Patent Rights; (b) in any such suit, enjoin infringement and collect for their 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; if NeoPharm or any Licensor do not notify NK within ninety (90) days of their intent to pursue legal action, NK will be free to initiate such action, provided that NeoPharm and any Licensor shall have a continuing right to intervene in such action. Subject to the foregoing, the indemnifying Party shall have the right to conduct the defense of any suit or action related to the Claim if it has assumed responsibility for the suit, action or other proceeding in writing; provided, however, that if in the reasonable judgment of the indemnified Party such suit, action or other proceeding involves an issue or matter which

could have a material adverse effect on the business, operations or assets of the indemnified Party, the indemnified Party may elect, at its own expense, to conduct a separate defense thereof, but in no event shall such election be construed as a waiver of any indemnification rights such indemnified Party may have under this Article 10, at law or in equity, or otherwise. If the indemnifying Party defends the suit or action, the indemnified Party may participate in (but not control) the defense thereof at its sole cost and expense; provided, however, that the indemnifying Party shall pay the reasonable fees and costs of any separate counsel required for the indemnified Party to the extent such representation is due to a conflict of interest between the Parties.

10.3 Settlements. Neither Party may settle any Claim, or any action or suit related to a Claim to a Third Party without the consent of the other Party, which consent shall not be unreasonably withheld, delayed or conditioned, if such settlement would impose any monetary obligation on the other Party or require the other Party to submit to an injunction or otherwise materially limit the other Party’s rights to conduct its business as then conducted or limit a Party’s rights under this Agreement, and any payment made by a Party in such a settlement without obtaining such consent shall be at its own cost and expense. Notwithstanding the foregoing, the indemnifying Party will be liable under this Article 10 for any settlement effected without its consent if the indemnifying Party has refused to acknowledge liability for indemnification hereunder and/or declines to defend the indemnified Party against any such Claim, or in any action or proceeding relating to a Claim and it is determined by dispute resolution pursuant to Article 13 hereof that the indemnifying Party was liable to the indemnified Party for indemnification related to such settlement.

10.4 Insurance. Each Party shall maintain suitable amounts of insurance coverage for clinical trials and commercial product liability proportionate to the risks and exposures and standard for the industry and the respective territories in which Products are developed and commercialized. The Parties shall work with one another to coordinate such appropriate insurance coverage for the activities contemplated by the Parties under this Agreement.

ARTICLE 11

11.1 Term of Agreement. This Agreement shall become effective as of the Effective Date and, unless earlier terminated pursuant to other provisions of this Article 11, shall continue in full force and effect until the date which is the tenth anniversary date of the First Commercial Sale of the Product in the Territory; provided, however, that in the event NK has obtained by such tenth anniversary date Governmental Approval for the sale of Product for an additional indication or new formulation or dosage or active component based on the Development conducted by NK according to the decision of the JSC, this Agreement shall continue in full force and effect until the date which is the tenth anniversary date of the date of such Governmental Approval (the “Term”). NK shall have the right, at its option, to extend the Term for such additional term (the “Additional Term”) as the Parties shall mutually agree in good faith, by giving NeoPharm the notice to that effect by [*] prior to the expiration of the Term or

each Additional Term. After expiration of this Agreement, including an Additional Term, if any, any and all rights and licenses granted hereunder regarding IL13, the Products and/or the Licensed Technology shall cease and terminate and shall revert back to NeoPharm.

11.2 Termination of Product Development. Should NK fail to actively pursue its efforts towards Development for a period of more than [] for any reason other than Force Majeure and a reasonable reason, such as a request by Governmental Authorities of the Territory, as determined in the reasonable judgment of the JSC, or should NK terminate at its discretion Development of IL13 and/or Products in the Territory by giving NeoPharm [] prior written notice, this Agreement shall terminate at the end of such applicable period and all rights of NK to the Licensed Technology or IL13 and/or the Products (including all data, information, physical manifestations and Regulatory Filings) in the Territory shall revert and be delivered to NeoPharm, and NK shall be free from any and all monetary or developmental obligations otherwise accruing thereafter. In addition, NeoPharm shall be granted a royalty-free worldwide exclusive license with sublicensing rights under the NK Technology and any Joint Inventions.

11.3 Default by NK. Upon any Default by NK under this Agreement, NeoPharm shall notify NK of such Default and, in the event such Default shall be a payment Default, require that NK cures such Default within fifteen (15) days or in the event such Default shall be a Default other than a payment Default, require that NK cures such Default within thirty (30) days. In the event NK shall not have cured the Default at the end of the applicable grace period, NeoPharm may terminate this Agreement. Upon termination of this Agreement pursuant to this Section 11.3, all rights of NK to the Licensed Technology, IL13 and the Products (including all data, information, physical manifestations and Regulatory Filings) in the Territory shall immediately revert to NeoPharm and NK will promptly return to NeoPharm all physical manifestations of the Licensed Technology. In addition, if NeoPharm terminates this Agreement pursuant to this Section 11.3, NK shall, free of charge, furnish promptly NeoPharm with NK Data which NK has at the time of such termination.

11.4 Default by NeoPharm. Upon the Default by NeoPharm under this Agreement, NK shall notify NeoPharm of such Default and require that NeoPharm cures such Default within thirty (30) days. In the event NeoPharm shall not have cured the Default at the end of the thirty (30) day grace period, at NK’s option, NK may terminate this Agreement or be relieved, without losing the license and sublicense to the Licensed Technology or any other right granted to NK under or pursuant to this Agreement (except to the extent NeoPharm’s license from any of its Licensors has been so terminated as to such Licensed Technology or other right), of any and all payment obligations other than those for supply of IL13 and/or Products by NeoPharm or any Third Party manufacturer to NK hereunder, until such time as NeoPharm has cured such Default. In addition, if NK has selected not to terminate this Agreement pursuant to this Section 11.4, NeoPharm shall, free of charge, furnish promptly NK with NeoPharm Data which NeoPharm has at the time of such selection. For Licensed Patent Rights for which the PHS is the Licensor, if NeoPharm’s license to any such patent estate is terminated, NK may either terminate this Agreement (with respect to the sublicense of such patent estate) or, at NK’s option, seek to convert such sublicense to a direct license between NK and PHS as specified in Section 2.5.

The Parties agree that the Parties as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code or other Applicable Laws. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against NK under the U.S. Bankruptcy Code or other Applicable Laws, NeoPharm shall to the extent legally possible be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and same, if not already in its possession, shall be promptly delivered to it (i) upon any such commencement of a bankruptcy proceeding upon its written request therefor, unless NK elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, upon the rejection of this Agreement by or on behalf of NK upon written request therefor by NeoPharm.

(c) Upon the termination of this Agreement by NeoPharm pursuant to this Section 11.5, all licenses to the Licensed Technology will revert to NeoPharm.

11.7 Termination or Modification by PHS. PHS has reserved the right according to 35 U.S.C. §209(f)(4) to terminate or modify NeoPharm’s license to the Licensed Patent Rights for which PHS is the Licensor if PHS determines that such action is necessary to meet requirements for public use specified by federal regulations issued after the date of the license and such requirements are not reasonably satisfied by NeoPharm. In the event NeoPharm

receives a notice relating to such termination or modification from PHS, NeoPharm shall immediately furnish to NK with a copy of such notice. In the event any license from PHS to NeoPharm relating to PHS’s Licensed Patent Rights is terminated, this Agreement shall terminate as to PHS’s Licensed Patent Rights, and within ninety (90) days of such termination, a final report shall be submitted by NK. Any Royalty payments, including those incurred but not yet paid, and those related to patent expense, due to NeoPharm shall become immediately due and payable. If terminated under this Section 11.7, NK may elect to seek to convert its sublicense to a direct license with PHS. If NK elects to convert the sublicense, such conversion will be subject to PHS approval and contingent upon acceptance by the sublicense of the remaining provisions of NeoPharm’s license with PHS, and if NK obtained such direct license from PHS, NK shall have the right to deduct the amount payable to PHS for such direct license from the License Fees, Milestone Payments and Royalties due pursuant to Article 4. Unless otherwise specifically provided for under this Agreement, upon such termination, NK shall return all materials included within the terminated Licensed Patent Rights to PHS or provide PHS with certification of the destruction thereof. If and to the extent PHS, or any other Licensor, shall modify NeoPharm’s license to the Licensed Patent Rights, the sublicense to NK granted hereunder shall be modified to the same extent, mutatis mutandis.

PHS shall not require the granting of a sublicense unless the responsible applicant has first negotiated in good faith with Licensee.

13.08		PHS reserves the right according to 35 U.S.C. §209(f)(4) to terminate or modify this Agreement if it is determined that such action is necessary to meet requirements for public use specified by federal regulations issued after the date of the license and such requirements are not reasonably satisfied by Licensee.

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 the materials.

8.01	Licensee agrees to keep accurate and correct records of Licensed Products made, used, or sold 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. They shall be available during normal business hours for inspection at the expense of PHS by an accountant or other designated auditor selected by PSH for the sole purpose of verifying reports and payments hereunder. The accountant or auditor shall only disclose to PHS information relating to the accuracy of reports and payments made under this Agreement. If an inspection shows an underreporting or underpayment in excess of five percent (5%) 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

D-1

	payments required under this Paragraph shall be due within thirty (30) days of the date PHS provides Licensee notice of the payment due.

10.01	Licensee shall use its reasonable best efforts to bring the License 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 D. 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.

12.05	Licensee shall indemnify and hold PHS, its employees, students, fellows, agents and consultants harmless from and against all liability, demands, damages, expenses, and losses, including but not limited to death, personal injury, illness, or property damage in connection with or arising out of a) the use by or on behalf of Licensee, its sublicensees, directors, employees, or third parties of any Licensed Patent Rights, or b) the design, manufacture, distribution, or use of any License Products, Licensed Processes or materials by Licensee, or other products or processes developed in connection with or arising out of the Licensed Patent Rights. Licensee agrees to maintain a liability insurance program consistent with sound business practice.

13.07	PHS reserves the right according to 35 U.S.C. §209(f)(4) to terminate or modify this Agreement if it is determined that such action is necessary to meet requirements for public use specified by federal regulations issued after the date of the license and such requirements are not reasonably satisfied by Licensee.

13.08	Within thirty (30) days of receipt of written notice of PHS’s unilateral decision to modify or terminate this Agreement, Licensee may, consistent with the provisions of 37CFR 404.11, appeal the decision by written submission to the designated PHS official. The decision of the designated PHS official shall be the final agency decision. Licensee may thereafter exercise any and all administrative or judicial remedies that may be available.

13.09	Within ninety (90) days of termination of this Agreement under this Article 13 or expiration under Paragraph 3.02, a final report shall be submitted by Licensee. Any royalty payments, including those related to patent expense, due to PHS shall become immediately due and payable upon termination or expiration. If terminated under this Article 13, sublicensees may elect to convert their sublicenses to direct licenses with PHS pursuant to Paragraph 4.03.

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 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 D.

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, and sales during the preceding calendar year, as well as plans for 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. 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 amend the Benchmarks at any Lime 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.

With each

E-8

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 certified as correct by an authorized officer of Licensee and shall include a detailed listing of all deductions made under Paragraph 2.11 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 sublicense.

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.

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. The taxes paid by Licensee on behalf of PHS may be deducted from the earned royalty due under paragraph 6.03.

9.08 Late charges will be assessed by PHS as additional royalties on any overdue payments at a rate of one (I) percent per month compounded monthly. 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, 5 U.S.C. § 552 shall be subject to the predisclosure notification requirements of 45 CFR § 5.65(d).

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, as well as any facts which may affect the validity, scope, or enforceability of the Licensed 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 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 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 Title 35, United States 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

E-10

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. H 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 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.

11.04 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 twenty-five percent (25%) 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 twenty-five percent (25%) 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 royal ties due in any calendar year to less than the minimum annual royalty.

REVISED PROPOSAL FOR THE CLINICAL AND

COMMERCIAL

DEVELOPMENT OF hIL13-PE38QQR AS ANTICANCER AGENT.

(U.s. Patent 5,614,191)

NeoPharm, Inc.

225 E. Deerpath Road

Suite 250

Lake Forest, IL 60045

E-25

NeoPharm’s Action Plan

The studies performed by Dr. Puri et al described the expression of interleukin-13 receptor on solid human tumor cells. The technology describes the fusion of receptor binding ligand, IL-13, to mutant form of a bacterial toxin, Pseudomonas exotoxin (PE38QQR). The chimeric protein known as hIL13-PE38QQR is expressed in Escherichia coli. The resulting fusion protein is obtained from the inclusion bodies in E. coli, from where they are isolated and purified. Based on this technology, the fusion protein has been extracted in sufficient quantities to perform the in vitro experiments in several human cell lines to derme the therapeutic potential of this technology. It has been demonstrated that the chimeric human protein hIL13-PE38QQR is cytotoxic in picomole concentration to human glioblastomas cells and renal cancer cells. These are highly exciting observations since IL-13 receptors are very exclusively expressed by the human solid tumors and not by the normal cells of the body so far examined. Hence, specific targeting to tumor sites with this chimeric protein should be more effective while avoiding the toxicities to the normal cells. This modality of treatment in cancer chemotherapy will be potentially preferred since treatment limiting toxicities of anticancer drugs are the major obstacles for the successful management of the disease. At present the technology describes the in vitro application, however, some preliminary in vivo efficacy data recently became available. Hence, a major thrust of our Development Plan will be to a) obtain large quantities of this chimeric protein and to derme whether b) chimeric protein is as effective in vivo as in vitro, c) to identify other tumor types which express IL-13 receptors such as pancreatic cancers, Kaposi’s sarcoma, prostate cancer and colon cancers, etc., d) to identify the toxicities of this chimeric protein in at least two animal species by administering it through i.v., or i.p., and to define the

E-26

LD₁₀, LD₅₀ and LD₁₀₀ doses in animals and e) to perform the clinical trials of this chimeric protein in various indications leading to the approval and marketing of this product.

1. Implement Plans to Independently Secure future Continuing Supplies of hIL13-PE38QQR for Preclinical and Clinical Development:

The chimeric protein hIL13-PE38QQR is extracted from Escherichia Coli from the inclusion bodies. The process which is developed by Dr. Puri, Dr. Pas tan and Dr. Debinski provides quantities which are sufficient for in vitro and in a limited scale for in vivo studies. However, for enlarged preclinical evaluation and for Phase I clinical use, the chimeric fusion protein has to be produced in larger quantities under Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP). NeoPharm believes that this task can be easily achieved by contracting out the scale-up production. With that consideration, NeoPharm has already identified three places where this chimeric protein can potentially be scaled-up. One of these is Inland Laboratories of Houston, Texas (contact person: Dr. Jerry Fulton), the second is Advanced Biosciences Laboratory, Kensington, MD (contact person: Dr. Phil Markhum) and the third is Biological Response Modifier Programs of NCI, Frederick, MD, where fee-for-service contracts are now accepted (contact person: Dr. Steve Creekmore). NeoPharm will select one of these sites for scale-up production after the formal approval of this licensing application. The scale-up production of this chimeric protein will be achieved with the full cooperation and participation of the inventors of this technology. The exact methodology of transfecting the E. Coli with the combined gene of IL-13R binding domain and the exotoxin gene expressing PE38QQR will be provided to contract manufacturer. The manufacturer will perform this transfection, the E. Coli are grown in controlled media and from the inclusion bodies, IL13-PE38QQR is extracted, purified by gel chromatography and HPLC method and analyzed by Western Blot for biological

E-27

characterization and cytotoxic characterization in Renal Cells Carcinoma (RCC cells). The scale-up chimeric protein has to meet all the criteria which are established by Dr. Puri’s laboratory at FDA. It is expected that the production of hIL13-PE38QQR in either of the places mentioned above would be sufficient for preclinical and Phase I studies with this protein. We expect that this chimeric protein should be available to us in sufficient quantity within one year of signing agreement. However, a major challenge would be to have enlarged quantities for Phase II trial leading to commercialization. This will involve identifying a pharmaceutical manufacturer with large fermentation capacity and resources to biologically characterize the chimeric protein production with full compliance of GLP and GMP requirements. We will undertake this task while the Phase I trials are in progress and the data supports the biological activity of hIL13-PE38QQR in a particular cancer type. In any situation, the investigators at FDA and NCI have to interact closely with the pharmaceutical manufacturer to validate the method and biologic activity of this chimeric protein with the established laboratory methods.

2. To further enhance the in vitro and in vivo studies of hIL13-PE38QQR:

Within four months following the availability of sufficiently large quantities of this chimeric protein hIL13-PE38QQR, further studies will be performed to evaluate its cytotoxicity in Kaposi’s sarcoma cells, prostate cancer and pancreatic cancer established cell lines. These cell lines will be maintained at Dr. Puri’s laboratory and necessary experiments will be performed there.

The in vivo therapeutic evaluation of the chimeric protein hIL13-PE38QQR will be performed in nude mice implanted with renal carcinoma cells and Kaposi’s sarcoma cells. These tumor cells will be implemented S.C. and when the tumor mass becomes about 50 mm3, mice will be randomly divided in a group of ten and will be injected i. v. with this chimeric protein. The

E-28

chimeric protein doses will range from 5 jlg/kg to 50 jlg/kg and will be administered three times at alternate days. The tumor volume will be calculated based on the formula, volume = (length) x (width)2 x (0.4). These doses will give a determination of minimal effective dose, most optimal dose as well as toxic therapeutic dose. The mice will be observed till day 60. The dose range employed in this study will determine the effectiveness of this modality of treatment in delaying the growth of the tumor, in completely curing the mice with tumor and also the cure rate of tumor with associated toxicities. It is expected that it will take about six months to complete these studies with necessary reporting to the company by the contractor.

3. In Vivo Toxicity Evaluation

It is possible that the chimeric protein hIL13-PE38QQR would bind and internalize non-specifically into normal tissues, particularly the liver, thus adversely compromising the therapeutic potential of this modality of treatment. Further, a safe starting dose for clinical trial in humans will be derived by the LDIO doses in mice and rats. Hence, nude mice will be injected i.v. with this chimeric protein at doses of 50 p.g - 250 p.g/kg on day 1, 3 and 5, having 10 mice at each dose level. Three days after the last dose, half of the mice in each group will be bled by orbital sinus, blood will be collected and chemistries will be performed. Mice will then be sacrificed by cervical dislocation and tissues will be fixed in formalin for histopathologic evaluation. The blood chemistry determination will define the alterations in liver function tests as well as any abnormalities in metabolic processes. The tissues such as liver and spleen with abnormalities will identify the possible non-specific binding of this chimeric protein to these organs and pathological lesions observed therein. All these studies will be performed in a GLP laboratory which is approved by FDA such as Hazelton Labs of Virginia.

E-29

A major concern with this chimeric protein is the manifestation of Vasculature Leakage Syndrome, VLS. This phenomenon has been observed with other immunotoxins such as LMB-l. Though the chimeric protein LMB-l is much bigger than the chimeric protein hIL13-PE38QQR, it is hoped that manifestations of VLS will be minimal with this agent. However, it will be highly prudent to evaluate the occurrence of this syndrome in mice and rats by histopathologic determinations established in Dr. Puri’s laboratory. This methodology will be established in the contract laboratory of NeoPharm to perform the VLS studies. In addition, the dose range we have selected with this chimeric protein hIL13 PE38QQR will define the LD₁₀ and LD₅₀ doses in nude mice. The understanding of these doses will define the safe starting dose of this chimeric protein in humans. The same studies will be performed in rats at equivalent doses of mice.

We expect these studies to be completed within six months.

Pharmacokinetic Studies

The phannacokinetic studies of the chimeric protein hIL13-PE38QQR will be performed in nude mice at a dose of 25 jLg/kg Lv. For this study, thirty mice will be used and three mice at specified time will be bled from orbital sinus and 100-200 jLl of blood will be collected at 5, 10, 15, 20, 30, 60 and 120 minutes and at 4, 6 and 24 hours. The serum will be separated and stored at -70°C before the determination of toxin levels. Levels of recombinant toxin will be determined by their cytotoxic activity toward renal cell carcinoma (RCC) cells using a standard curve generated by the cytotoxic activity of purified toxin toward RCC cells. (These methods are well established in Dr. Puri’s laboratory). The levels of toxin in the serum will be assayed by the contract laboratory as identified by NeoPharm. In addition, the tissues will be homogenized in saline, centrifuged and supernatant will be assayed for the toxin levels by the established

E-30

methods. These studies will provide the plasma half-life, area under the plasma concentration curve, clearance, and volume of distribution as well as tissue distribution of this toxin. The attached chart describes the major activities which NeoPharm will be supporting for hIL13-PE38QQR. We expect that this portion of studies will be completed within six months.

4. Clinical Evaluation of hIL13-PE38QQR Chimeric Protein:

Within six months of having performed the in vivo toxicity and therapeutic evaluation of this chimeric protein, NeoPharm will submit an IND for the initiation of Phase I clinical trial. This Phase I trial will be designed by NeoPharm and Dr. Puri and other collaborators at FDA and NCI. A major thrust of this Phase I protocol would be to identify the toxicities and if possible, efficacy of this chimeric protein at various dose levels. The starting Phase I dose of this chimeric protein will be 1/10h of the LD₁₀ dose in mice. Assuming the LD₁₀ dose of hIL13-PE38QQR to be 500 fJ.g/kg, the starting dose of Phase I in patients will be 50 fLg/kg. Three patients will receive this dose level and will be evaluated fully for the next three weeks for any toxicities. If no toxicities are observed, a cohort of three patients will be started with 50 % higher dose level of the initial dose and will be observed similarly for three weeks. If no grade 3 or 4 toxicities are observed, then the dose will be escalated to 100% i.e. 100 fJ.g/kg in the next cohort of 3 patients. This scheme of dose escalation will be continued in patients till grade 3 or 4 toxicities are encountered. If that happens, then the dose will be reduced to half the previous dose to describe in more detail the toxicities in 3 more patients. This will then be defined as the maximum tolerated dose (MTD). It is expected that the whole Phase I trial will enroll about 25 patients. It is executed that this Phase I trial will take about one year to be completed with full clinical evaluation of the data.

E-31

Patients eligible for this study will have a histologic diagnosis of a malignant solid tumor and have exhausted the available chemotherapeutic protocols for their disease, or have a malignant disease for which no palliable therapy is available. Where possible, biopsy samples of the tumor will be obtained to determine the IL-13 receptor sites. To enroll in the study, patients must be over 18 years of age and a KPS of at least 70%, with adequate bone marrow reserves and no organ function abnormality. All patients must provide an informed, written consent in accordance with Federal and Institutional guidelines. Though patients with any kind of malignancies will be enrolled, the investigators will give preference to enroll kidney cancer patients with distant metastasis to have some feeling about the performance of the chimeric protein hIL13-PE38QQR in the planned Phase II setting. In this Phase I trial all the patients, before therapy, will be required to have a medical history, physical examination, complete blood counts, biochemical profile analysis, electrocardiograms, chest x-rays and CAT scans as required for establishing the index of lesions. Patients will be monitored weekly for most of the above tests to define the occurrence of any toxicities as well as for the appearance of any antibodies either related to the recombinant protein receptor or recombinant exotoxin. Toxicities will be documented according to the Common Toxicity Criteria, Clinical Trials Evaluation Program, National Cancer Institute. Patients will be very carefully evaluated for Vascular Leakage Syndrome, fluid retention, hypotension, pulmonary edema and dyspnea.

NeoPharm’s Plan and Support for Clinical Development Leading to FDA Approval for Marketing.

After the completion of Phase I trial of hIL13-PE38QQR, NeoPharm will start a Phase II trial with the MTD doses of this chimeric protein in kidney cancer patients with metastasis. This trial will enroll 20 patients to defme the efficacy of this chimeric protein for this indication. The

E-32

enrollment criteria will include histologic diagnosis of a malignant tumor which has not responded to conventional chemotherapy. Those patients should not have been treated with any immune modulator and do not express any antibodies for any known immune modulator. This exclusion criteria ensures that overlapping toxicities are not manifested to mask any effect of this therapy. This Phase II trial will take six to nine months to be completed. If there are two responders in this limited Phase II trial, then NeoPharm, in concurrence with FDA, will start an enlarged Phase II trial at various cancer centers. This enlarged Phase II trial will enroll at least 150 patients who have been newly diagnosed with the cancer. It is estimated that this Phase II trial will take about 18 months to be completed. Since there is no approved drug for kidney cancer patients, a randomized Phase II trial would possibly be not required under the present guidelines of Cancer Drug Approval of FDA as initiated by Clinton Administration. Though IL-2 is indicated for kidney cancer patients with KPS 0-1, however, patients with KPS 2-4 are contraindicated and therapy does not appear to have any clinical activity rather appears to be more toxic to those patient population. Hence, it is expected that this enlarged Phase II trial will serve as a pivotal trial leading to the approval of drug from FDA depending on the clinical outcome and eventual approval for commercialization of this chimeric protein. NeoPharm expects to submit a BLA application six months after the enlarged Phase II trial is completed. However, if the FDA feels that we have to perform a Phase II trial to justify the approval of this agent for commercialization, NeoPharm will undertake the trial which will enroll 300 patients to establish the efficacy of this agent for renal cell carcinoma and will take a minimum of two years to complete it.

To seek further indications for this chimeric protein as cancer therapeutic agent, NeoPharm will support Phase II trials of hIL13-PE38QQR in Kaposi’s sarcoma and brain cancer patients. The

E-33

preliminary data which is gathered in the laboratory of Dr. Puri provides the justification for the initiation of these trials. Depending on the clinical outcome of these trials and the clinical efficacy of this chimeric protein for these neoplasms, decisions will be made by NeoPharm and FDA and NCI investigators to either up-scale the efforts or downsize the efforts. In any situation, it will be prudent for the company to seek one indication aggressively and dedicate most of the resources for that clinical indication.

NeoPharm will collect all the clinical data, perform the statistical analysis, compile the clinical efficacy and for each patient list the adverse reactions observed. The company will compile the whole CMC relating to the commercial production of this chimeric protein. All this work will be done independently by the Company to avoid any perceived or factual appearance of the conflict of interest with FDA due to the association of the inventors. As has been described in the various action plan of the company, NeoPharm will become a major partner with FDA and NCI investigators in promoting efforts and clinical trials for this chimeric protein hIL13-PE38QQR. However, when the approval application for marketing of this chimeric protein is prepared, there will be an arms length relationship between the company and FDA, NCI investigators. The eventual marketing of this compound at reasonable cost will have a major impact on overall well being of the cancer patients. It is hoped that these efforts by NeoPharm will provide access for this compound to community oncologist for a wider spectrum of needy patients and will eventually improve their quality of life, and as well as extend the survival rates of those patients.

ADDENDUM TO PROTOCOL

The following is the addendum for the quality control testing of the IL-13 chimeric protein. This addendum becomes an integral part of the attached protocol.

The homogeneity of the chimeric protein will be performed by:

1. SDS - polyacrylamide gel filtration

2. Reverse- phase HPLC

In addition, the final product will also be tested for endotoxin levels. If the desired levels are not achieved, the endotoxin will be removed by chromatographic methods until satisfactory levels are achieved.

6.07 No multiple royalties shall be payable because any Licensed Product(s) or Licensed Process(es) are covered by more than one of the Licensed Patent Rights.

E-42

6.08 On sales of Licensed Product(s) by Licensee to sublicensees or on sales made in other than an arm’s length transaction, the value of the Net Sales attributed under this Article 6 to such a transaction shall be that which would have been received in an arm’s length transaction, based on sales of like quantity and quality products on or about the time of such transaction.

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 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.

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 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 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 Patent Rights and shall furnish copies of relevant patent related documents to Licensee.

E-43

7.02 Upon PHS’s written request, Licensee shall assume the responsibility for the preparation, filing, prosecution, and 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 consult 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 VHS deems necessary to undertake such responsibilities. If PHS elects to assume control of the preparation, filing, prosecution and maintenance of any and all patent applications or patents included in the Licensed Patent Rights for a reason other than Licensee’s failure to perform under this Agreement, PHS shall be responsible for all costs associated with transferring patent prosecution responsibilities to an attorney or agent of PHS’s choice.

7.04 Each party 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. RECORD KEEPING

8.01 Licensee agrees to keep accurate and correct records of Licensed Product(s) made, used, sold, or imported and Licensed Process(es) 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 disclose to PHS information relating to the accuracy of reports and payments made under this Agreement. If an inspection shows an

E-44

underreporting or underpayment in excess of five percent (5%) 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 and royalties conducted by an independent auditor at least every two (2) years if annual sales of the Licensed Product or Licensed Process(es) are over two (2) million dollars. The audit may be conducted in conjunction with the annual audit performed on behalf of Licensee. 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 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 for 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. 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 amend the Benchmarks 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

E-45

request is supported by a reasonable showing by Licensee of diligence in its performance under the Commercial Development Plan and toward bringing the Licensed Product(s) to the point of Practical Application as defined in 37 CFR Part 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 Licensed 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 Product(s) sold or Licensed Process(es) 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 certified 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 PUS by Licensee for activities under the sublicense.

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 ###-###-####. 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.

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. The taxes paid by Licensee on behalf of PHS maybe deducted from the earned royalty due under paragraph 6.03.

E-46

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 front 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: §552 shall be subject to the predisclosure notification requirements of 45 CFR part 5.65(d).

10. PERFORMANCE

10.01 Licensee shall use its reasonable commercial efforts to bring the Licensed Product(s) and Licensed Process(es) to Practical Application. “Reasonable commercial 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 commercial efforts to make Licensed Product(s) and Licensed Process(es) reasonably accessible to the United States public.

10.03 Licensee agrees, after its First Commercial Sale, to make reasonable quantities of Licensed Product(s) or materials produced through the use of Licensed Process(es) available on a compassionate use basis to patients, either through the patient’s physician(s) and/or the medical center treating the patient.

10.04 Licensee further agrees, after its First Commercial Sale and as part of its marketing arid product promotion, to develop written educational materials (e.g., brochures, advertisements, etc.) directed to patients and physicians detailing the Licensed Product(s) and its use to treat cancer.

10.05 PHS acknowledges that information and materials related to the Licensed Patent Rights may be of assistance to Licensee in its commercialization efforts. Accordingly, PHS, at its discretion, will consider reasonable requests by Licensee for access to the inventors of the Licensed Patent Rights with regard to this information and materials. More specifically, PHS agrees to provide Licensee with information and materials, if available, related to the cDNA, mRNA, sequence data. etc., that might be necessary for the development and commercialization of the Licensed Product(s) and/or the Licensed Process(es) in the Licensed Fields of Use.

E-47

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, as well as any facts which may affect the validity, scope, or enforceability of the Licensed 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 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 shall 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 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.

APPENDIX F - Commercial Development Plan

The technology described in the Licensed Patent Rights will be used as gene therapy for various types of cancers. Several years ago Dr. Raj Puri at FDA identified the receptors for Interleukin 13 (IL-13) on various human tumors. Subsequently, he showed that a chimeric protein IL-13 PE38QQR is highly cytotoxic to those cancers, which express high levels of IL-13 receptors, such as renal cell carcinoma, glioblastoma and Kaposi’s sarcoma. In addition, it was demonstrated that the primary IL-13 binding protein, IL-13 Ra2 chain, plays a dominant role in ligand binding and internalization. This chain is expressed on a variety of cancer cell lines; however, some cancer cell types express low levels of this receptor chain. Because of this low level expression of IL-13-Ra2 chain, these cells show very little sensitivity to the targeted toxin IL-13-PE38QQR. It was proposed that gene transfer of this chain with cancer cells might increase their sensitivity to IL-13 toxin. Hence, IL-13-Ra2-chain gene was cloned from human glioma cell lines and inserted into expression vector for gene transfer. It has been demonstrated that head and neck cancer cells that are not sensitive to IL-13 PE38QQR acquired pronounced sensitivity as a result of gene transfer of IL-13-Ra2. In addition, remarkable antitumor activity was observed in two tumor models of head and neck cancer cells transfected with IL-13-Ra2 gene in vivo.

The field of use for this gene transfer modality could be quite important in cancer chemotherapy for localized tumors such as head and neck cancers, prostate cancers and brain cancers. It is possible to sensitize these cancers by intratumoral or systemic transfer of IL-13-Ra2 gene.

A major thrust of the Licensee’s Commercial Development plan will be a) to obtain large quantities of this cDNA and identify the most effective vector for the plasmid; b) to evaluate the in vivo efficacy of this gene therapy in various tumor models by systemic administration; c) to identify the toxicities of this plasmid and the vector in at least two animal species by administering it through i.v. and s.c. administration; to define LD₁₀, LD₅₀ and LD₁₀₀ doses in animals and d) to perform the clinical trials of this plasmid with the appropriate vector in various indications leading to the regulatory approval and marketing of this technology.

The various steps of drug development outlined above are defined more elaborately as benchmarks mutually agreed upon between Licensee and PHS and are listed in Appendix E of this Agreement. The Licensee will perform quite diligently to achieve these defined benchmarks leading to the marketing of this product, The Licensee is already performing Phase Il/III trials with IL-13-PE38QQQR in brain cancer, glioblastoma. The Licensee intends to expedite the commercial development of this immunotoxin with the concurrent development of this gene therapy technology for cancer cells to overexpress high levels of IL-13 receptors. The Licensee is willing to commit the necessary financial resources for the successful development of this technology.
