(a)

In addition to the reserved license of Paragraph 5.1, PHS reserves the right to grant Research Licenses directly or to require Licensee to grant Research Licenses on reasonable terms. The purpose of these Research Licenses is to encourage basic research, whether conducted at an academic or corporate facility. In order to safeguard the Licensed Patent Rights, however, PHS shall consult with Licensee before granting to commercial entities a Research License or providing to them research samples of materials made through the Licensed Processes; and

(b)

In exceptional circumstances, and in the event that Licensed Patent Rights are Subject Inventions made under a CRADA, the Government, pursuant to 15 U.S.C. §3710a(b)(1)(B), retains the right to require the Licensee to grant to a responsible applicant a nonexclusive, partially exclusive, or exclusive sublicense to use the Licensed Patent Rights in the Licensed Field of Use on terms that are reasonable under the circumstances, or if Licensee fails to grant this license, the Government retains the right to grant the license itself. The exercise of these rights by the Government shall only be in exceptional circumstances and only if the Government determines:

(i)

the action is necessary to meet health or safety needs that are not reasonably satisfied by Licensee;

(ii)

the action is necessary to meet requirements for public use specified by Federal regulations, and these requirements are not reasonably satisfied by the Licensee; or

(iii)

the Licensee has failed to comply with an agreement containing provisions described in 15 U.S.C. §3710a(c)(4)(B); and

8.	RECORD KEEPING

8.1

Licensee agrees to keep accurate and correct records of Licensed Products made, used, sold, or imported and Licensed Processes practiced under this Agreement appropriate to determine the amount of royalties due PHS. These 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 royalty payments hereunder. The accountant or auditor shall only disclose to PHS information relating to the accuracy of reports and royalty 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 additional royalties as required by Paragraph 9.8. All royalty payments required under this Paragraph shall be due within thirty (30) days of the date PHS provides Licensee notice of the payment due.

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

9.1

Prior to signing this Agreement, Licensee has provided PHS with the Commercial Development Plan in Appendix E, 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.

9.2

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 these differences. In the 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 approval by PHS. PHS shall not unreasonably withhold approval of any request of Licensee to extend the time periods of this schedule if the request is supported by a reasonable showing by Licensee of diligence in its performance under the Commercial Development Plan and toward bringing the Licensed Products to the point of Practical Application as defined in 37 CFR §404.3(d). Licensee shall amend the Commercial Development Plan and Benchmarks at the request of PHS to address any Licensed Fields of Use not specifically addressed in the plan originally submitted.

9.3

Licensee shall report to PHS the dates for achieving Benchmarks specified in Appendix D and the First Commercial Sale in each country in the Licensed Territory within thirty (30) days of such occurrences.

9.4

Licensee shall submit to PHS, within sixty (60) days after each calendar half year ending June 30 and December 31, a royalty report, as described in the example in Appendix F, setting forth for the preceding half year period the amount of the Licensed Products sold or Licensed Processes practiced by or on behalf of Licensee in each country within the Licensed Territory, the Net Sales, and the amount of royalty accordingly due. With each royalty report, Licensee shall submit payment of 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.

9.5

Licensee agrees to forward semi annually to PHS a copy of these 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.

9.6

Royalties due under Article 6 shall be paid in U.S. dollars and payment options are listed in Appendix G. 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. 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 9.4 shall be mailed to PHS at its address for Agreement Notices indicated on the Signature Page.

9.7

Licensee shall be solely responsible for determining if any tax on royalty income is owed outside the United States and shall pay the tax and be responsible for all filings with appropriate agencies of foreign governments.

9.8

Additional royalties may be assessed by PHS on any payment that is more than ninety (90) days overdue at the rate of one percent (1%) per month. This one percent (1%) per month rate may be applied retroactively from the original due date until the date of receipt by PHS of the overdue payment and additional royalties. The payment of any additional royalties shall not prevent PHS from exercising any other rights it may have as a consequence of the lateness of any payment.

9.9

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 these 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 §5.65(d).

10.	PERFORMANCE

10.1

Licensee shall use its reasonable commercial efforts to bring the Licensed Products and Licensed Processes to Practical Application. “Reasonable commercial efforts” for the purposes of this provision shall include adherence to the Commercial Development Plan in Appendix E and performance of the Benchmarks in Appendix D. The efforts of a sublicensee shall be considered the efforts of Licensee.

10.2

Upon the First Commercial Sale, until the expiration or termination of this Agreement, Licensee shall use its reasonable commercial efforts to make Licensed Products and Licensed Processes reasonably accessible to the United States public.

10.3

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

10.4

Licensee agrees, after its First Commercial Sale and as part of its marketing and product promotion, to develop educational materials (e.g., brochures, website, etc.) directed to patients and physicians detailing the Licensed Products or medical aspects of the prophylactic and therapeutic uses of the Licensed Products.

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.

11.2

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 suit, enjoin infringement and collect for its use, damages, profits, and awards of whatever nature recoverable for the infringement; or

(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; and

(d)

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 the suit. Licensee shall take no action to compel the Government either to initiate or to join in any suit for patent infringement. Licensee may request the Government to initiate or join in any suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any suit, Licensee shall reimburse the Government for any costs, expenses, or fees which the Government incurs as a result of the motion or other action, including all costs incurred by the Government in opposing the 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.

11.3

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 11.2, pursuant to this Agreement and the provisions of Chapter 29 of Xxxxx 00, Xxxxxx Xxxxxx 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 suit, ultimately to enjoin infringement and to collect for its use, damages, profits, and awards of whatever nature recoverable for the 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 these actions and shall have a continuing right to intervene in the suit; and

(d)

If PHS does not notify Licensee of its intent to respond to the legal action within a reasonable time, Licensee shall be free to do so. Licensee shall take no action to compel the Government either to initiate or to join in any declaratory judgment action. Licensee may request the Government to initiate or to join any suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any 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 the motion or other action. If Licensee elects not to defend against the 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.

11.4

In any action under Paragraphs 11.2 or 11.3 the expenses including costs, fees, attorney fees, and disbursements, shall be paid by Licensee. The value of any recovery made by Licensee through court judgment or settlement shall be treated as Net Sales and subject to earned royalties.

11.5

PHS shall cooperate fully with Licensee in connection with any action under Paragraphs 11.2 or 11.3. PHS agrees promptly to provide access to all necessary documents and to render reasonable assistance in response to a request by Licensee.

12.	NEGATION OF WARRANTIES AND INDEMNIFICATION

12.1

PHS offers no warranties other than those specified in Article 1.

12.2

PHS does not warrant the validity of the Licensed Patent Rights and makes no representations whatsoever with regard to the scope of the Licensed Patent Rights, or that the Licensed Patent Rights may be exploited without infringing other patents or other intellectual property rights of third parties.

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 Licensed Products, Licensed Processes or materials by Licensee, or other products or processes developed in connection with or arising out of the Licensed Patent Rights.

12.6

Licensee agrees to maintain a liability insurance program consistent with sound business practice.

13.	TERM, TERMINATION, AND MODIFICATION OF RIGHTS

13.1

This Agreement is effective when signed by all parties, unless the provisions of Paragraph 14.16 are not fulfilled, and shall extend to the expiration of the last to expire of the Licensed Patent Rights unless sooner terminated as provided in this Article 13.

13.2

In the event that Licensee is in default in the performance of any material obligations under this Agreement, including but not limited to the obligations listed in Paragraph 13.5, and if the default has not been remedied within ninety (90) days after the date of notice in writing of the default, PHS may terminate this Agreement by written notice and pursue outstanding royalties owed through procedures provided by the Federal Debt Collection Act.

13.3

In the event that Licensee becomes insolvent, files a petition in bankruptcy, has such a petition filed against it, determines to file a petition in bankruptcy, or receives notice of a third party's intention to file an involuntary petition in bankruptcy, Licensee shall immediately notify PHS in writing. Furthermore, PHS shall have the right to terminate this Agreement immediately upon Licensee's receipt of written notice.

13.4

Licensee shall have a unilateral right to terminate this Agreement or any licenses in any country or territory by giving PHS sixty (60) days written notice to that effect.

13.5

PHS shall specifically have the right to terminate or modify, at its option, this Agreement, subject to paragraph 13.2, if PHS determines that the Licensee:

(a)

is not executing the Commercial Development Plan submitted with its request for a license and the Licensee cannot otherwise demonstrate to PHS’ reasonable satisfaction that the Licensee has taken, or can be expected to take within a reasonable time, effective steps to achieve Practical Application of the Licensed Products or Licensed Processes;

(b)

has not achieved the Benchmarks as may be modified under Paragraph 9.2;

(c)

has willfully made a false statement of, or willfully omitted a material fact in the license application or in any report required by the license Agreement;

(d)

has committed a material breach of a covenant or agreement contained in this Agreement;

(e)

is not keeping Licensed Products or Licensed Processes reasonably available to the public after commercial use commences;

(f)

cannot reasonably satisfy unmet health and safety needs; or

(g)

cannot reasonably justify a failure to comply with the domestic production requirement of Paragraph 5.2 unless waived.

13.6

In making the determination referenced in Paragraph 13.5, PHS shall take into account the normal course of such commercial development programs conducted with sound and reasonable business practices and judgment and the annual reports submitted by Licensee under Paragraph 9.2. Prior to invoking termination or modification of this Agreement under Paragraph 13.5, PHS shall give written notice to Licensee providing Licensee specific notice of, and a ninety (90) day opportunity to respond to, PHS’ concerns as to the items referenced in 13.5(a)-13.5(g). If Licensee fails to alleviate PHS’ concerns as to the items referenced in 13.5(a)-13.5(g) or fails to initiate corrective action to PHS’ reasonable satisfaction, PHS may terminate this Agreement.

13.7

When the public health and safety so require, and after written notice to Licensee providing Licensee a sixty (60) day opportunity to respond, PHS shall have the right to require Licensee to grant sublicenses to responsible applicants, on reasonable terms, in any Licensed Fields of Use under the Licensed Patent Rights, unless Licensee can reasonably demonstrate that the granting of the sublicense would not materially increase the availability to the public of the subject matter of the Licensed Patent Rights. PHS shall not require the granting of a sublicense unless the responsible applicant has first negotiated in good faith with Licensee.

13.8

PHS reserves the right according to 35 U.S.C. §209(d)(3) to terminate or modify this Agreement if it is determined that this action is necessary to meet the requirements for public use specified by federal regulations issued after the date of the license and these requirements are not reasonably satisfied by Licensee.

13.9

Within thirty (30) days of receipt of written notice of PHS' unilateral decision to modify or terminate this Agreement, Licensee may, consistent with the provisions of 37 CFR §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.

13.10

Within ninety (90) days of expiration or termination of this Agreement under this Article 13, a final report shall be submitted by Licensee. Any royalty payments, including those incurred but not yet paid (such as the full minimum annual royalty), and 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 4.3. Unless otherwise specifically provided for under this Agreement, upon termination or expiration of this Agreement, Licensee shall return all Licensed Products or other materials included within the Licensed Patent Rights to PHS or provide PHS with certification of the destruction thereof.

14.	GENERAL PROVISIONS

14.1

Neither party may waive or release any of its rights or interests in this Agreement except in writing. The failure of the Government to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right by the Government or excuse a similar subsequent failure to perform any of these terms or conditions by Licensee.

14.2

This Agreement constitutes the entire agreement between the parties relating to the subject matter of the Licensed Patent Rights, Licensed Products and Licensed Processes, and all prior negotiations, representations, agreements, and understandings are merged into, extinguished by, and completely expressed by this Agreement.

14.3

The provisions of this Agreement are severable, and in the event that any provision of this Agreement shall be determined to be invalid or unenforceable under any controlling body of law, this determination shall not in any way affect the validity or enforceability of the remaining provisions of this Agreement.

14.4

If either party desires a modification to this Agreement, the parties shall, upon reasonable notice of the proposed modification by the party desiring the change, confer in good faith to determine the desirability of the modification. No modification shall be effective until a written amendment is signed by the signatories to this Agreement or their designees.

14.5

The construction, validity, performance, and effect of this Agreement shall be governed by Federal law as applied by the Federal courts in the District of Columbia.

14.6

All Agreement notices required or permitted by this Agreement shall be given by prepaid, first class, registered or certified mail or by an express/overnight delivery service provided by a commercial carrier, properly addressed to the other party at the address designated on the following Signature Page, or to another address as may be designated in writing by the other party. Agreement notices shall be considered timely if the notices are received on or before the established deadline date or sent on or before the deadline date as verifiable by U.S. Postal Service postmark or dated receipt from a commercial carrier. Parties should request a legibly dated U.S. Postal Service postmark or obtain a dated receipt from a commercial carrier or the U.S. Postal Service. Private metered postmarks shall not be acceptable as proof of timely mailing.

14.7

This Agreement may not be assigned without prior written permission from PHS except to an Affiliate, which permission shall not be unreasonably withheld. Licensee shall provide PHS a minimum of sixty (60) days to grant the written permission. In the event that no response from PHS during the sixty (60) day period is received, Licensee shall consider the permission granted. Licensee shall pay PHS, as an additional royalty, one percent (1%) of the fair market value of any consideration received for any assignment of this Agreement within thirty (30) days of the assignment.

14.8

Licensee agrees in its use of any PHS supplied materials to comply with all applicable statutes, regulations, and guidelines, including PHS and HHS regulations and guidelines. Licensee agrees not to use the materials for research involving human subjects or clinical trials in the United States without complying with 21 CFR Part 50 and 45 CFR Part 46. Licensee agrees not to use the materials for research involving human subjects or clinical trials outside of the United States without notifying PHS, in writing, of the research or trials and complying with the applicable regulations of the appropriate national control authorities. Written notification to PHS of research involving human subjects or clinical trials outside of the United States shall be given no later than sixty (60) days prior to commencement of the research or trials.

14.9

Licensee acknowledges that it is subject to and agrees to abide by the United States laws and regulations (including the Export Administration Act of 1979 and Arms Export Control Act) controlling the export of technical data, computer software, laboratory prototypes, biological material, and other commodities. The transfer of these items may require a license from the appropriate agency of the U.S. Government or written assurances by Licensee that it shall not export these items to certain foreign countries without prior approval of this agency. PHS neither represents that a license is or is not required or that, if required, it shall be issued.

14.10

Licensee agrees to xxxx the Licensed Products or their packaging sold in the United States with all applicable U.S. patent numbers and similarly to indicate “Patent Pending” status. All Licensed Products manufactured in, shipped to, or sold in other countries shall be marked in a manner to preserve PHS patent rights in those countries.

14.11

By entering into this Agreement, PHS does not directly or indirectly endorse any product or service provided, or to be provided, by Licensee whether directly or indirectly related to this Agreement. Licensee shall not state or imply that this Agreement is an endorsement by the Government, PHS, any other Government organizational unit, or any Government employee. Additionally, Licensee shall not use the names of NIH, FDA, PHS, or HHS or the Government or their employees in any advertising, promotional, or sales literature without the prior written approval of PHS.

14.12

The parties agree to attempt to settle amicably any controversy or claim arising under this Agreement or a breach of this Agreement, except for appeals of modifications or termination decisions provided for in Article 13. Licensee agrees first to appeal any unsettled claims or controversies to the designated PHS official, or designee, whose decision shall be considered the final agency decision. Thereafter, Licensee may exercise any administrative or judicial remedies that may be available.

14.13

Nothing relating to the grant of a license, nor the grant itself, shall be construed to confer upon any person any immunity from or defenses under the antitrust laws or from a charge of patent misuse, and the acquisition and use of rights pursuant to 37 CFR Part 404 shall not be immunized from the operation of state or Federal law by reason of the source of the grant.

14.14

Any formal recordation of this Agreement required by the laws of any Licensed Territory as a prerequisite to enforceability of the Agreement in the courts of any foreign jurisdiction or for other reasons will be carried out by Licensee at its expense, and appropriately verified proof of recordation will be promptly furnished to PHS.

14.15

Paragraphs 4.3, 8.1, 9.5-9.7, 12.1-12.5, 13.9, 13.10, and 14.13 of this Agreement shall survive termination of this Agreement.

14.16

The terms and conditions of this Agreement shall, at PHS’ sole option, be considered by PHS to be withdrawn from Licensee’s consideration and the terms and conditions of this Agreement, and the Agreement itself to be null and void, unless this Agreement is executed by the Licensee and a fully executed original is received by PHS within sixty (60) days from the date of PHS signature found at the Signature Page.

XXXXXXXX X – COMMERCIAL DEVELOPMENT PLAN

The ultimate objective of the CRADA is to identify, characterize, and bring to clinical trial regimens for the treatment of human brain tumors (GBMs) and other Central Nervous System (CNS) tumors. Lixte Biotechnology Holdings, Inc., the parent company of Licensee will most likely conduct such a clinical trial in association with NINDS.

Licensee is in contact with several large pharmaceutical companies with major programs in development and evaluation of anti-cancer drugs about co-developing one or more phosphatase ligands shown to have anti-cancer activity in vitro and in vivo in the CRADA studies. Licensee, however, is prepared to work with NINDS and /or other branches of NIH to develop these compounds through pre-clinical evaluation and clinical testing without the addition of a larger pharmaceutical partner.

To facilitate this approach, NINDS has submitted an application to the NIH RAID PILOT program to be reviewed in the summer of 2008. If approved, NINDS would collaborate with Licensee to complete pre-clinical development of one lead compound under the RAID program through to submission of an IND to the FDA for a Phase I trial. The Phase I trial could be done with one of several large academic brain tumor centers in the US, including the surgical neurology branch of NINDS. Following completion of Phase I testing, Licensee is committed to supporting Phase II evaluations with or without an additional partner from the pharmaceutical industry.
