Any license granted by the Licensor under the terms of this Agreement shall be subject to this right of the United States Government.

4.5 The Parties acknowledge that the United States Government (acting through its agent National Institutes of Health) reserves the right to require the Licensor, or Can-Fite, to grant sublicenses to responsible applicants, on terms that are reasonable under the circumstances when necessary to fulfill health or safety needs or when necessary to meet requirements for public use specified by United States Federal regulations.

5. Payment

5.1 Within thirty (30) days of the Commencement Date, Can-Fite shall pay to the Licensor a license signing fee (“Signing Fee”) of twenty five thousand Euros (Euro 25,000).

5.2 In addition, as of the year of 2009, Can-Fite shall pay to the Licensor an annual non-refundable minimum royalty of ten thousand Euros (Euro 1 0,000) (“Minimum Annual Royalty”) within sixty (60) days of the start of each calendar year.

5.3 Can-Fite agrees to pay to the Licensor a royalty of three percent (3%) on Net Sales Value provided that Can-Fite shall be entitled to a credit of one-half percent (0.5%) against the royalty rate for each percent point in excess of two percent (2.0%) that Can-Fite must pay to an unaffiliated licensor for the manufacture and sale of Products. Said credit, however, shall not reduce the earned royalty due to the Licensor below two percent (2.0%) of Net Sales value.

Can-Fite agrees to pay the Licensor milestone payments in relation to the undernoted key milestones being achieved by Can-Fite or a sublicensee as follows:

1. Start of Phase I studies	EURO 50,000
2. Start of Phase II studies	EURO 100,000

(b)     Ten percent (10%) of all non-creditable and non-refundable consideration received for granting a sublicense. Fees paid expressly for research and development of Products and Processes, such as clinical trial support, shall be excluded.

5.5 In the event that Can-Fite shall transfer to a transferee that aspect of its business involving this agreement, Can-Fite agrees to pay the Licensor an assignment royalty of ten percent 10%) of all payments received for such a transfer of this agreement, provided, however, that no such royalty shall be owed to the Licensores in the event that the foregoing transfer is part of or results from a merger, consolidation or other reorganization of the Can-Fite or from a sale, exchange or other transfer of all or substantially all of its assets. For the removal of any doubt, for any transaction in which an assignment royalty as stipulated in this clause 5.5 will be due, no sublicensing royalty will be payable, as set out in Clause 5.4; and vice versa. Further Can-Fite will ensure that the transferee will be bound by the terms of this agreement, including, but not limited to, the payment of royalties set out in Clauses 5.1 to 5.4 above as well as that set out in this clause 5.5..

5.7 Payments due under Clauses 5.3 and 5.5 shall be made to Leiden within [30] days of the end of each calendar year in respect of royalties accruing on Products invoiced in that calendar year failing which interest shall be payable at the rate of three per centum above the Base Lending Rate.

5.8 All sums due under this Agreement shall be made in full without deduction of taxes, charges and other duties that may be imposed except in so far as any such deduction may be credited in full by the Licensor against the Licensor’s own tax liabilities. The parties agree to cooperate in all respects necessary to take advantage of such double taxation agreements as may be available.

5.9 For the avoidance of doubt, Leiden shall make arrangements to share the revenue received under this Clause 5 with National Institutes of Health, all in accordance with the terms of a separate interinstitutional agreement.

The accountant may take copies of the records and books of account but shall not disclose to the Licensor any information relating to the business or affairs of Can-Fite other than such information as properly should have been contained in any statement required to be furnished by Can-Fite to the Licensor. The Licensor shall be solely responsible for the costs of the accountant unless he certifies that any reports are inaccurate in any material respect in which event Can-Fite shall reimburse the Licensor for all his costs.

6.2 Can-Fite shall submit to Leiden within [30] days of the end of each calendar year a statement setting forth the quantity of Products made, used or sold, the Net Sales Value of Products and all income associated with sublicensing activity, for the immediately preceding calendar year.

9.1 During the continuance of this Agreement:

9.1.1 Can-Fite shall use its reasonable commercial efforts to develop the Products. Can-Fite will submit a commercial development plan within 12 months from the Agreement Date. The commercial development plan will then be incorporated into this Agreement as Part 2 of the Schedule. It is understood that it is within the nature of research and development that development route and the expected timelines may change and that the commercial development plan may have to be modified. Accordingly, Can-Fite may request Licensor from time to time to amend the commercial development plan, a request which will not be unreasonable denied.

6

In order to safeguard the Patent Rights, however, each of the joint owners shall consult with Can-Fite before providing to commercial entities research samples of Products.

7

10. Patents

10.1 It is acknowledged by all parties that Can-Fite has borne all costs associated with the prosecution of the Patent Rights since the Effective Date. In addition it is now agreed that this responsibility shall continue from the Commencement Date such that for the duration of this Agreement, Can-Fite shall at its own cost diligently prosecute to grant all subsisting patent applications within the Patent Rights in at least the Primary Territories, as defined below, so as to secure the broadest monopoly reasonably obtainable consistent with avoiding serious prejudice to the validity of such granted patents and shall maintain all patents within the Patent Rights in force for the full terms thereof. Said Primary Territories include the US, UK, France, Germany, Italy, Switzerland, Japan, Canada and Australia.

10.2 In the event of any infringement by a third party of any of the Patent Rights in the Territory on such a scale as to affect prejudicially Can-Fite’s business in the Products to a substantial extent, Can-Fite may take all legitimate steps to halt such infringement. Can-Fite may request the Licensor or any of the Inventors or any other inventor of the Patent Rights to lend its names to such proceedings and provide reasonable assistance subject to Can-Fite giving them an indemnity in respect of all costs, damages and expenses that they may incur including any award of costs against them [in so far as the aggregate of all such costs and damages may exceed that recoverable under the next following provisions]. Where such infringement proceedings are conducted by Can-Fite under the name of the Licensor, Can-Fite may apply all royalties due under Clauses 5.2 and 5.3 subsequent to the date of notification by Can-Fite to the Licensor of the relevant infringement to defray any costs directly incurred by Can-Fite (excluding award of costs in favour of third parties) provided however that the total liabilities or waiver of royalties of the Licensor hereunder shall in no circumstances exceed the sum of all royalties due subsequent to that date and up to the date of the delivery of the final decision in the relevant infringement proceedings and provided further that this provision shall only apply subject to Can-Fite exercising all due diligence in pursuing the proceedings to a conclusion. Any damages recovered shall be dealt with in a manner which shall be fair and reasonable as between the Licensor and Can-Fite.

10.3 As at the Commencement Date, to the best of the Licensor’s knowledge and belief the exercise of the rights granted or to be granted to Can-Fite hereunder will not result in the infringement of valid patents of third parties. Subject thereto, the Licensor gives no warranty in this respect and do not give Can-Fite any indemnity against costs, damages, expenses or royalties arising out of proceedings brought against Can-Fite or any customer of Can-Fite by any third party. Should Can-Fite be sued for infringement of any patent or patents of the third party by reason of its operation of the Process or manufacture, use or sale of the Products, the Licensor shall, on request, assist Can-Fite in its defence to such action to the extent that in all the circumstances it is reasonable to do so but shall otherwise be under no obligations in respect thereof. All costs of any such action shall be borne by Can-Fite to whom shall belong all sums that may be recovered from the third party.

10.4 If at any time during this Agreement Can-Fite directly or indirectly opposes or assists any third party to oppose the grant of letters patent on any patent application within the Patent Rights or disputes or directly or indirectly assists any third party to dispute the validity of any patent within the Patent Rights or any of the claims thereof, the Licensor shall be entitled at any time thereafter to terminate all or any of the licences granted hereunder forthwith by notice thereof to Can-Fite.

8

11. Termination

11.1 If any party is in breach of any of its obligations and, in the case of a breach capable of remedy, it shall not have been remedied by the defaulting party within 90 days of written notice specifying the breach and requiring its remedy, or if Can-Fite becomes apparently insolvent, has a receiver or administrator appointed over the whole or any part of its assets, enters into any compound with creditors, or has an order made or resolution passed for it to be wound up (otherwise than in furtherance of a scheme for amalgamation or reconstruction) then the Licensor or, in the case of breach, the party not in breach of the obligation or condition, may forthwith terminate this Agreement by written notice without prejudice to the accrued rights of either party.

11.2 On termination of this Agreement for any reason, Can-Fite shall continue to have the right for a period of twelve (12) months from the date of termination to complete deliveries on contracts in force at that date and to dispose of Products already manufactured subject to payment to the Licensor of royalties thereon in accordance with Clause 5 above.

11.3

11.3 .1 During the term of this Agreement, the Licensor may terminate this Agreement when:

(a) it is determined by the Licensor in discussion with National Institutes of Health Office of Technology Transfer that:

(i) Termination is necessary to alleviate health or safety needs which are not reasonably satisfied by Can-Fite;

(ii) Termination is necessary to meet requirements for public use specified by Federal law or regulations and these requirements are not reasonably satisfied by Can-Fite; or

(iii) Termination is necessary because the requirements of 35 U.S.C. §204 have not been satisfied or waived or because a licensee of the exclusive right to use or sell the Patent Rights in the United States is in breach of its agreement obtained pursuant to Section 204; and

(b) Can-Fite has been notified of this determination and has been given at least ninety (90) days to provide a response to this determination, and the response is deemed to be unsatisfactory by the Licensor, in consultation with National Institutes of Health.

Patent costs incurred by Can-Fite prior to termination under this Article 11.4 shall be promptly reimbursed by the Licensor.

12. General

12.1 This Agreement shall be binding upon and ensure to the benefit of the parties hereto and their respective legal successors but shall not otherwise be assignable by Can-Fite without the written consent of the Licensor, which consent shall not be unreasonably withheld.

9

12.3 Each and every provision of this Agreement shall be read (where possible) as entirely independent and severable from the other provisions. In all cases where a provision of this Agreement is reducible, invalid or unenforceable in terms of any legislation or other legal authority, such provision shall not affect the validity of the remaining portion of this Agreement which shall remain in force and effect as if this Agreement had been granted with no such provision and it is hereby declared the intention of the parties that they would have executed the remaining portion of this Agreement without including therein any such provisions.

12.4 A failure by a party to exercise or enforce any rights conferred upon it by this Agreement shall not be deemed to be a waiver of any such rights or operate so as to bar the exercise or enforcement thereof at any subsequent time or times.

12.7 The text of any press release or other communication to be published by or in the media concerning the subject matter of this Agreement shall require the approval of each party.

13. Notices

13.1 Any notice required to be given hereunder by any party shall be in writing and shall be served by sending the same by registered post to the address of the other party as given herein.
