CONFIDENTIAL TREATMENT REQUESTED

This Agreement is effective on the date last subscribed below (the “Effective Date”), and is by and between Sloan-Kettering Institute for Cancer Research (hereinafter referred to as “SKI”), a New York membership corporation with principal offices at 1275 York Avenue, New York, New York 10065, and MabVax Therapeutics, Inc., a corporation with principal offices located at 11588 Sorrento Valley Road, Suite 20, San Diego, CA 92121 (“Company”).

WITNESSETH

WHEREAS, SKI has been engaged in research efforts focused on the development of conjugated tumor antigens as cancer vaccines; and

WHEREAS, SKI plans to conduct human clinical trials on such cancer vaccines which are expected to generate antisera against tumor antigens; and

WHEREAS, Company has expertise in the discovery, development and production of monoclonal antibodies using the lymphocytes of naturally exposed or vaccinated donors; and

WHEREAS, Company seeks to commercially develop monoclonal antibodies derived from the SKI human clinical trials for therapeutic and diagnostic uses through a vigorous and diligent program whereby public utilization shall result therefrom;

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein, the parties hereto agree as follows:

ARTICLE 1

DEFINITIONS

For the purpose of this Agreement, the following words and phrases shall have the following meanings:

1.1 “Affiliate” shall mean any person, firm, corporation or other entity controlling, controlled by, or under common control with a party hereto. For the purpose of the preceding sentence, the term “control” shall mean ownership, directly or indirectly, of more than 50% of the equity capital or the authority, directly or indirectly, to appoint a majority of the directors of another entity. With regard to SKI, “Affiliate” shall mean the Memorial Sloan-Kettering Cancer Center and the Memorial Hospital for Cancer and Allied Diseases.

1.2 “Biological Material” shall mean human blood and lymphocytes obtained from patients enrolled in the Participating SKI Clinical Trials.

1.3 “Collaboration Materials” shall mean (i) any and all materials (including without limitation monoclonal antibodies) developed in the course of the Development Program using the Biological Material and (ii) any derivatives of the foregoing materials.

CONFIDENTIAL TREATMENT REQUESTED

1.4 “Commercially Reasonable Efforts” shall mean the efforts and resources of similarly situated companies that are consistent with sound business judgment taking into consideration product labeling, the development potential, regulatory environment, market potential, economic return, and competitive market conditions, all measured by the facts and circumstances at the time such efforts are due.

1.5 “Development Program” shall mean the research to be conducted by Company as described in Exhibit B.

1.6 “Development Technology” shall mean (i) any and all Collaboration Materials, and (ii) any and all intellectual property rights in and to any Program Inventions (including, without limitation, Program Patent Rights).

1.7 “FDA” shall mean the United States Food and Drug Administration, its equivalent in another country, or successor agencies thereto.

1.8 “First Commercial Sale” means, in each country, the first commercial sale, where sale means delivery, billing out or invoicing, whichever comes first, of a Licensed Product by Company, its Affiliates or sublicensees to any person or entity other than Company, its Affiliates or sublicensees following Regulatory Approval in the country in which the sale is made.

1.9 A “Licensed Process” shall mean any process which is covered in whole or in part by a Valid Claim of the SKI Program Patent Rights or Joint Program Patent Rights in any country in which such process is practiced.

1.10 A “Licensed Product” shall mean any product or part thereof made, leased, used or sold by or on behalf of Company which:

(a) is or contains a Collaboration Material; or

(b) is covered in whole or in part by a Valid Claim of SKI Program Patent Rights or Joint Program Patent Rights in the country in which any product or part thereof is made, leased, used or sold; or

1.11 “Net Sales” shall mean Company’s and its Affiliates and sublicensees’ gross invoiced sales of Licensed Products or Licensed Processes less the sum of the following:

(a) Discounts actually allowed and granted (including, without limitation, cash discounts and quantity discounts), retroactive price reductions, charge-back payments and rebates granted to managed health care organizations or to federal, state and local governments, their agencies, and purchasers and reimbursers or to trade customers (a “Discount”); provided however, that where any such Discount is based on sales of a bundled set of products in which such Licensed Product is included, the Discount shall be allocated to such Licensed Product on a

CONFIDENTIAL TREATMENT REQUESTED

pro rata basis based on the sales value (i.e., the unit average selling price multiplied by the unit volume) of the Licensed Product relative to the sales value contributed by the other constituent products in the bundled set, with respect to such sale;

(b) Credits or allowances actually granted upon claims, damaged goods, rejections or returns of such Licensed Product, including such Licensed Product returned in connection with recalls or withdrawals;

(d) Taxes, tariffs, excise, sales, duties, or other taxes levied on, absorbed or otherwise imposed on the sale of such Licensed Product or Licensed Process, including, without limitation, value-added taxes, or other governmental charges otherwise imposed upon the billed amount, as adjusted for rebates and refunds, to the extent not paid by a third party; and

(e) Bad debts and uncollectible receivables provided that, in any calendar year, such deduction for bad debts and uncollectible receivables will not exceed four percent (4%) of the total billings for sales of Licensed Products and Licensed Processes sold in that year.

In the event a drug product in a finished dosage form contains a Licensed Product in combination with one or more other therapeutically active ingredients or with a carrier molecule or an immunological adjuvant (in each case, a “Combination Product”), the Net Sales of the Licensed Product, for the purposes of calculating royalty payments of this Agreement, shall be determined by multiplying the Net Sales (as defined above in this Section) of the Combination Product by the fraction, A/(A+B) where A is the weighted (by sales volume) average invoice price in a particular country of the Licensed Product when sold separately in finished form and B is the weighted average invoice price in that country of the other active ingredient(s) sold separately in finished form. In the event that such average invoice price cannot be determined for both the Licensed Product and the other active ingredient(s) in the Combination Product, Net Sales for purposes of determining royalty payments shall be agreed by the parties based on the relative value contributed by each component. In the case of a Combination Product that contains one or more other therapeutically active ingredients, in no event shall Net Sales for purposes of determining royalty payments be less than fifty percent (50%) of the Net Sales of the Combination Product. In the case of a Combination Product that contains a carrier molecule or adjuvant but does not contain another therapeutically active ingredient, in no event shall Net Sales for purposes of determining royalty payments be less than seventy five percent (75%) of the Net Sales of the Combination Product.

For purposes of calculating Net Sales, sales between or among Company or its Affiliates or sublicensees shall be excluded from the computation of Net Sales, but sales by Company or its Affiliates or sublicensees to third parties shall be included in the computation of Net Sales.

CONFIDENTIAL TREATMENT REQUESTED

Licensed Products shall be considered “sold” when billed or invoiced. In the case of any sale which is not invoiced or is delivered before invoice, Net Sales shall be calculated at the time of shipment or when the Licensed Product is paid for, if paid for before shipment or invoice.

In the case of any sale or other disposal for value, such as barter or counter-trade, of the Licensed Product, or part thereof, other than in an arm’s-length transaction exclusively for money, Net Sales shall be calculated as above on the value of the non-cash consideration received or the fair market price (if higher) of the Licensed Product in the country of sale or disposal.

No deductions shall be made for commissions paid to individuals whether they be with independent sales agencies or regularly employed by Company and on its payroll, or for cost of collections.

Net Sales shall be determined in accordance with GAAP.

Notwithstanding the foregoing or any other provision of this Agreement to the contrary, Licensed Products for which Company receives no consideration used (i) for promotional or sampling purposes and (ii) in preclinical studies or clinical trials or in compassionate use programs, shall not be considered in determining Net Sales.

1.12 “Non-Royalty Sublicense Revenue” shall mean the amount actually received by Company from sublicensees arising from the grant of a sublicense of the right to make or sell Licensed Products or Licensed Processes, including, but not limited to, up-front license fees, license issue fees, maintenance fees and milestone payments paid by a sublicensee to Company in consideration for the grant by Company of a sublicense of the right to make or sell Licensed Products or Licensed Processes; provided, however, that “Non-Royalty Sublicense Revenue” shall in any event exclude: (A) royalties paid to Company by a sublicensee based on such sublicensee’s sale of Licensed Products or Licensed Processes; (B) any payments by a sublicensee to Company that are tied directly to the provision of goods and services by Company to such sublicensee (including, without limitation, research and development funding) to compensate Company for the fair market value of the provision of such goods and services; (C) payments for equity or debt securities of Company (except to the extent such payments exceed the fair market value of such securities on the date of issuance); and (D) reimbursement of patent costs actually incurred by Company.

ARTICLE 8

REPORTS AND RECORDS

8.1 Company shall keep, and shall require its Affiliates and sublicensees to keep, full, true and accurate books of account containing all particulars that may be necessary for the purpose of showing the amounts payable to SKI hereunder. Said books and records shall be maintained for a period of no less than four (4) years following the period to which they pertain. SKI shall have the right to cause an independent, certified public accountant reasonably acceptable to Company to audit such records to confirm payments due hereunder for a period covering not more than the preceding four (4) years. Such audits may be exercised no more than once per year during normal business hours upon reasonable prior written notice to Company. No accounting period of Company shall be subject to audit more than one time for the same purpose. SKI shall bear the full cost of such audit unless such audit discloses an underpayment by Company of more than ten percent (10%) or $50,000, for any twelve (12) month period, in which case, Company shall bear the full cost of such audit and shall promptly remit to SKI the amount of any underpayment, plus interest as stipulated in Section 6.5.

8.2 Company, within sixty (60) days after June 30 and December 31 of each year, shall deliver to SKI true and accurate reports, giving such particulars of the business conducted by Company and its sublicensees during the preceding six-month period under this Agreement as shall be pertinent to a royalty accounting hereunder. Company shall use commercially reasonable efforts to obtain such reports from sublicensees as are necessary to fulfill its reporting requirements under this Section 8.2, but it shall not be deemed a material breach of this Agreement by Company if, notwithstanding Company’s commercially reasonable efforts, Company is unable to timely report regarding its sublicensees’ activities as a result of such sublicensees’ failure to timely provide the requisite information to Company. These shall include at least the following, to be itemized per Licensed Product and Licensed Process:

(a) Number of Licensed Products and Licensed Processes commercially used, manufactured and sold, rented or leased.

(b) Total billings for Licensed Products and Licensed Processes commercially used, sold, rented or leased.

Development Program

1.1

Collection of Lymphocytes from Target Donors and Incorporation into the MabVax Antibody Generation Process

MabVax will coordinate the initial antibody generation efforts with the currently planned Phase I and 11 clinical trial program scheduled to begin in the first quarter of 2008 at MSKCC.

MabVax will make reasonable efforts to rescue human monoclonal antibodies derived from SKI Biological Materials using established MabVax know-how and technology that has been used successfully in the past. SKI will provide the respective antigens and cell lines in sufficient amount and quality to enable screening for antibody producing cells and evaluation of antibody binding (ELISA and other assays). The initial goal is to generate antibody producing hybridoma cells that are specific for the antigens used for vaccination. Multiple sequential antibody generation efforts will be initiated as lymphocytes become available from individuals with a demonstrated immune response to at least one of the antigens.

1.2

Generation of Primary Panel of Antibodies to Each Cancer Antigen

Cells that produce specific antibodies of interest will be expanded and subcloned, if possible, and the variable sequence of the antibodies will be cloned and rescued by Molecular Biology technology (PCR). The variable sequence will be inserted into a full length human IgG antibody and expressed in mammalian cells to generate recombinant human antibodies. MabVax intends to generate a panel of 10 or more distinct antibodies specific for each of the antigens used in the vaccines. The isolated antibodies will be sequenced and classified according to the current antibody nomenclature.

1.3

Evaluation of Each Panel of Antibodies to Select Lead Antibody for In Vitro Testing

The human antibodies will initially be selected based on binding to the specific antigen as measured by ELISA. Subsequent testing will establish antigen specificity and reactivity with the native antigen expressed on cells by flow cytometry. More stringent functional assays will also be used to probe the utility of antibodies. For example, the ability of the antibody candidates to mediate complement mediated lysis utilizing human complement will be evaluated. In addition, the antibodies will be tested for in vitro activity in complement dependent and complement independent cell mediated lysis assays (ADCC assays). Small scale production (1-10 mg amounts) and purification will be done to obtain sufficient material to perform these in vitro assays.

1.4

Selection of Lead Antibody Candidates for Each Antigen

CONFIDENTIAL TREATMENT REQUESTED

SK#13624

The next goal is to select the most promising candidates for further development. Antibody candidates with promising specificity, affinity and effector function activity in vitro will be scaled up further to produce antibodies at the several 100 mg scale. Selection of a high producing cell line(s) and adaptation to serum-free media will be performed. Once sufficient antibody is generated, the efficacy of the selected candidates will be determined in suitable murine cancer models. Initially it is planned to focus on [*****] which is expressed on an available syngeneic murine malignancy (the EL4 lymphoma). Xenogenic models involving subcutaneous or intravenous administration of human cancer cells lines into nude mice or, as recently described for a series of SCLC cell lines, NK depleted SCID mice will also be pursued.

The efficacy of selected, most promising lead candidate antibodies may be further evaluated to compare stand alone or combination treatment. It is anticipated that the proposed in vivo studies will lead to the selection of antibody lead candidates that merit further preclinical and clinical development efforts.
