STRICTLY PRIVATE AND CONFIDENTIAL

AGREEMENT

This Agreement (“Agreement”) is entered into and signed as of November 21, 2011, by and between Can-Fite Biopharma Ltd., an Israeli corporation, of 10 Bareket Street, Petach Tikva, Israel (“Can-Fite”), for the first part; and Denali Concrete Management, Inc., a Nevada corporation, of 123 W. Nye Lane, Suite 129 Carson City, NV 89706 (“Denali”), for the second part. Can-Fite and Denali may be referred to herein individually as a “Party” or collectively as the “Parties”.

WHEREAS, Can-Fite desires to grant to Denali a worldwide exclusive license over its therapeutic drug CF 101 for the field of ophthalmic diseases (the “Field”) in exchange for the issuance to Can-Fite of shares and warrants of Denali representing approx. 86.7% of the issued share capital of Denali (the “Transaction”); and

WHEREAS, the Board of Directors of each of Can-Fite and Denali has determined that it is desirable to effect the Transactions.

NOW THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, and intending to be legally bound hereby, the Parties agree as follows

1.           Grant of License. Subject to the terms and conditions contained herein, Can-Fite shall grant to a newly incorporated Israeli subsidiary of Can-Fite (the “Sub”) an exclusive license to CF-101 for the Field (the “License”), in exchange for the issuance to Can-fite of 1,000 ordinary shares, nominal value NIS 0.01 each of the Sub, representing 100% of the issued and outstanding share capital of the Sub. The License shall be granted pursuant to a mutually agreed upon license agreement (the “License Agreement”), which shall include customary provisions as are typically included in such license agreements, including timetables for the development and commercialization for CF 101 in the field, and shall be signed and executed by the relevant parties at the Closing (as defined below).

2.          Recapitalization. Prior to the Closing and as a condition thereto, Denali shall perform a recapitalization of its share capital so that of the 11,370,430 Common Stock, par value US$0.001 each (the “Common Stock”) issued and outstanding as of the date hereof, 7,750,000 shall be repurchased by Denali and returned to treasury and 1,920,000 shall be issued to certain investors in exchange for an investment to be used in order to pay for all the liabilities of Denali prior to the Closing, so that immediately prior to the Closing the authorized share capital of Denali shall consist of 1,000,000 shares of Preferred Stock, none of which shall be issued and outstanding, and 50,000,000 shares of Common Stock, of which 5,540,430 shall be issued and outstanding (the “Recapitalization”).

3.          Transfer of Sub to Denali. At Closing, Can-Fite shall transfer 1,000 ordinary shares of the Sub (representing 100% of the outstanding interests in the Sub) to Denali, free and clear of all liens and encumbrances, pursuant to such stock transfer and conveyance instruments as shall be reasonable and customary for similar transfers.

4.          Issuance of Shares and Warrants to Can-Fite. In consideration for the grant of the License to the Sub and the transfer of all (100%) of the issued shares of the Sub to Denali, Denali shall issue to Can-Fite thirty-six million (36,000,000) shares of Common Stock of Denali, representing 86.7% of the issued and outstanding share capital (on a fully diluted basis) as of the Closing (the “Transaction Shares”). The capitalization table of Denali immediately prior to and after the Closing shall be set out herein as Exhibit A.

5.          Financing. Concurrently with the Closing and as a condition thereto or prior thereto, Denali shall raise not less than US$6.2 Million from investors through a private placement, of which US$3.8 Million shall be in cash (of which US$500,000 will be invested by Can-Fite prior to the grant of the License) and US$2.4 Million will be in ordinary shares of Can-Fite, whose value at the date of their issuance to Denali shall be equal to US$2.4 Million, all for the issuance to the investors and Can-Fite of 5,445,086 Common Stock of Denali at a price per share of US$1.144 per each such share, and an aggregate valuation, pre private placement, of US$50 Million. For each two (2) shares of Denali purchased in the Financing, each investor (including Can-Fite) will be issued, post Closing and conditional on the increase of the share capital of Denali, if increased, one (1) warrant valid for a period of 5 years from the closing of the Financing, to acquire one (1) share of Denali for an exercise price of $1.72, which is 50% higher than the price per share in the Financing ($1.144). Denali further agreed to apply a full-ratchet anti-dilution protective provisions for the benefit of the investors in the Financing (including Can-Fite) in the event that Denali enters into another financing during the 12 months following the closing of the Financing at a price which is lower than $1.144 per common stock of Denali. In connection with the Financing Denali expects to pay cash commissions to third parties in the amount of approximately $330,000 (the “Fundraising”). The proceeds of the Fundraising shall be used to continue the clinical development of CFIOI in the Field, it being understood that additional future financing will probably be required to complete such clinical development. The investors will invest in the Fundraising through a mutually agreed upon subscription agreement which shall include customary terms and conditions for such transactions, which shall include that upon the Closing the investment amount placed in escrow prior to the Closing shall be released to Denali immediately after the Closing upon issuance of the investment shares (the “Investment Shares”) to such investors (the “Subscription Agreement”). For avoidance of doubt, if the valuation of the Fundraising won’t be approved by Can-Fite, at its sole discretion, then the Agreement will expire and cease to have any legal effect.

6.          Service Agreement. Concurrently with the Closing, Can-Fite shall enter into a service agreement with Denali or its affiliate for the management of all activities relating to pre-clinical and clinical studies performed for the development of the ophthalmic indications in the Field, including pre-clinical studies, drug manufacturing and supply, QT study in human beings, payments to consultants such as Dr. Bill Kerns and Dr. Mike Silverman for their role involved in the on-going clinical trials and all activities need to be conducted in order to launch CF 101 to the market for the ophthalmic indications (the “Service Agreement”). The terms of the Service Agreement shall set out that Can-Fite shall invoice Denali for such services to be provided by Can-Fite at a rate of cost of such services + 15% (not including VAT, if applicable), and shall “pass through” any direct payments for intellectual property maintenance made to third parties. Furthermore, the Service Agreement shall include additional compensation for the services being performed under the Service Agreement in the form of a royalty to be paid to Can-Fite from any and all proceeds received by the Sub, Denali or any of its affiliates in relation to CF 101 in the Field, of 2.5% of any such proceeds (the “Royalty”). In addition, the Service Agreement shall contain customary provisions as typically set out in similar agreements. Denali will undertake to be obligated to all current ongoing ophthalmic clinical trials’ agreements signed by Can Fite, and will pay all payments according to those agreements from the date of the Closing onwards. Denali shall also undertake to pay all other costs related to the ophthalmic indications such as IP maintenance, regulatory activities etc. Can-Fite will have the right, at any time until the expiry of 5 years from the Closing, to convert the Royalty into an additional 2,160,102 shares of Common Stock of Denali, which shall be equal to 5% of the issued and outstanding share capital (on a fully diluted as converted basis) as of the Closing (the “Warrants”). The exercise price of the Warrants shall be as follows: (a) in the event that within 12 months of the Closing, Denali or its affiliates complete any transaction which has a “bio-dollar” value of more than US$100 Million, then the exercise price shall be the par value of the shares of Common Stock, and (b) at any other time, then exercise price for ALL the Warrants shall be US$2.5 Million (which represents an assumed valuation as of the Closing of US$50 Million). Additional terms and conditions of the Warrants shall include anti-dilution, cashless exercise and other customary terms and conditions which shall be set out in a mutually agreed upon Warrant agreement (the “Warrant Agreement”).

7.          Closing. The Parties contemplate that a closing will take place as soon as practical following the execution and delivery of this Agreement, but no later than November 22, 2011 (the “Closing”), at which all of the following shall occur concurrently: (a) CanFite shall grant the License to the Sub, (b) all of the Sub’s shares shall be transferred to Denali, (c) Denali shall issue to Can-Fite 36,000,000 shares of Common Stock representing 86.7% of the issued and outstanding share capital of Denali, (d) Denali shall issue to Can-Fite the Warrant, (e) Subscription Agreements in relation to not less than US$6.2 Million (including by way of receipt of Ordinary Shares of Can-Fite valued at US$2.4 Million) will have been signed and executed by investors with the respective investment amount placed in escrow to be released immediately following the Closing, and (f) all other Transaction Agreements shall be signed, executed and delivered by the parties thereto. “Transaction Agreements” shall mean this Agreement, the License Agreement, the Warrant Agreement, the Subscription Agreements, the Service Agreement and any additional agreements, documents or instruments required to complete the Transactions.
