The other Party shall have [***] to notify the first Party in writing whether it agrees or disagrees that such potential target is within the RSPO-LGR Pathway. If the other Party agrees in writing that such potential target is within the RSPO-LGR Pathway, then such potential target shall be added to Exhibit C-2 and shall be a RSPO Umbrella Target. If the other Party disagrees in writing that such potential target is within the RSPO-LGR Pathway, then such dispute shall be resolved in accordance with Section 2.2.9 below. If [***] such potential target is within the RSPO-LGR Pathway in accordance with Section 2.2.9, then such potential target shall be added to Exhibit C-2 and shall be a RSPO Umbrella Target. If [***] such potential target is not within the RSPO-LGR Pathway, then such potential target shall not be added to Exhibit C-2, shall not be deemed a RSPO Umbrella Target, and shall be deemed an Excluded Target and added to the Excluded Target List. Notwithstanding anything to the contrary contained herein, if such potential target is an Excluded Target with respect to the RSPO-LGR Pathway, then such potential target may not be added to Exhibit C-2, [***], and shall not be deemed a RSPO Umbrella Target.

(ii) For clarity, a RSPO Umbrella Target may be removed from the list set forth on Exhibit C-2 only upon the Parties’ mutual consent, or will be automatically removed from Exhibit C-2, upon designation of a RSPO Umbrella Target as a RSPO Designated Target pursuant to Section 2.2.4(c) or 2.2.5.

(i) The Target for the applicable RSPO Designated Program shall be the target set forth in the RSPO Designation Notice provided by Celgene to OncoMed in accordance with the following procedure: During the applicable Pathway Designation Term, OncoMed shall at each JSC meeting (but in no event later than [***] after the end of each Calendar Quarter), (A) issue a written notice identifying any RSPO Umbrella Targets that are on the list of RSPO Umbrella Targets on Exhibit C-2, and any Protein Therapeutics Specifically Directed to each RSPO Umbrella Target, (B) provide all material data and information relating to each RSPO Umbrella Target and each Protein Therapeutic identified in such notice (provided, that if such data and information was previously disclosed to Celgene as set forth in this Section 2.2.4(c)(i), in lieu of disclosing such data and information, OncoMed may provide a general description of such data and information and state that it was previously disclosed), including

[***]

[***], and (C) identify any Protein Therapeutic Specifically Directed to a RSPO Umbrella Target that has met the Candidate Selection Criteria (as determined by the JSC pursuant to Section 4.2.3), and provide Celgene with material data and information relating thereto, so that Celgene may determine whether it would like to designate such RSPO Umbrella Target as a RSPO Designated Target (a “Candidate RSPO Umbrella Target”). The draft initial development plan for Development of any such Protein Therapeutic is set forth on Exhibit D-4a. Celgene may request [***]. Further, upon Celgene’s reasonable request, OncoMed shall provide samples and/or materials [***], in accordance with Section 2.5.1, to the extent necessary or reasonably useful to enable Celgene to evaluate whether it wishes to designate a RSPO Umbrella Target (including a Candidate RSPO Umbrella Target) as a RSPO Designated Target.

(ii) Within [***] after OncoMed provides notice to the JSC of a Candidate RSPO Umbrella Target pursuant to 2.2.4(c)(i), Celgene shall determine and notify OncoMed in writing whether it will designate such Candidate RSPO Umbrella Target as a RSPO Designated Target pursuant to Section 2.2.4(c)(iii); provided, that if Celgene requests [***] during the first [***] of such [***] period, then such period will be automatically extended (as necessary) so that such period ends on the [***] following [***].

(iii) At any time during the applicable Pathway Designation Term, and subject to Sections 2.2.5 and 2.2.6, Celgene may, in its sole discretion, elect to designate any RSPO Umbrella Target (including any Candidate RSPO Umbrella Target) as a “RSPO Designated Target” by issuing a written notice to OncoMed so identifying such RSPO Umbrella Target (such notice, a “RSPO Designation Notice”), upon which Exhibit C-2a, C-2b, etc. shall be automatically added to this Agreement listing such RSPO Designated Target. Effective as of such RSPO Designation Notice delivery, such RSPO Designated Target shall no longer be a RSPO Umbrella Target (or Candidate RSPO Umbrella Target, if applicable) and shall no longer be within the RSPO Umbrella Program, and each Protein Therapeutic that is Specifically Directed to such RSPO Umbrella Target shall be a “RSPO Product Candidate” (if it otherwise satisfies such definition) with respect to such RSPO Designated Program. The Parties shall establish and mutually agree upon the IDP for each RSPO Designated Target within [***] after designation thereof, which shall be automatically added to this Agreement as Exhibit D-4b, D-4c, etc.

(iv) The Parties hereby acknowledge and agree that, notwithstanding the definition of “RSPO Product Candidate” with respect to a RSPO Designated Program, OncoMed may [***]. Solely in such event, for purposes of this Section 2.2.4(c), the “RSPO Designated Target” shall consist of [***], and the “RSPO Designated Program” shall include each Protein Therapeutic directed to [***] as a “RSPO Product Candidate” (if it otherwise satisfies such definition) with respect to such RSPO Designated Program.

For the avoidance of doubt, termination of any particular Program(s) or the [***]SM Program pursuant to this Section 11.2.1 shall not terminate (i) this Agreement with respect to any other Program(s) or the [***]SM Program, as applicable, or (ii) any Development & Commercialization Agreement for any other Program, or the [***]SM Agreement.

If the Executive Officers are unable to resolve a dispute within such [***] period after it is referred to them, the matter will be resolved as provided in Section 12.7.

11.2.3 Payments. [***]; provided, however, if either Party provides notice of a dispute pursuant to Section 11.2.2 or otherwise and such dispute is resolved in a manner in which no termination of this Agreement occurs with respect to such breach or the breaching Party cures the applicable breach during the Cure Period, then upon such resolution or cure [***].

11.3 Voluntary Termination. Celgene may terminate this Agreement in its entirety or with respect to one or more Programs or the [***]SM Program upon one hundred twenty (120) days’ prior written notice to OncoMed hereunder at any time (it being understood and agreed that Celgene shall be entitled to terminate upon sixty (60) days’ written notice at any time it reasonably determines that such termination is necessary to comply with any Antitrust Law), except that any such termination of this Agreement with respect to any Program as to which Celgene has exercised its Option shall not be permitted during the term of such Development & Commercialization Agreement for such Program, and except that any such termination of this Agreement with respect to the [***]SM Program shall not be permitted during the term of the [***]SM Agreement. For the avoidance of doubt, any such termination of any particular Program(s) or the [***]SM Program pursuant to this Section 11.3 shall not terminate any other Program(s) or the [***]SM Program, and any such termination of the [***]SM Program shall not terminate any Programs.

In connection therewith, the provisions of Section 7.1.5 shall apply.

11.5 Termination for Patent Challenge. OncoMed shall have the right to terminate this Agreement on a Program-by-Program basis upon written notice if Celgene or any Affiliate (as defined in Section 1.3(a)) challenges the validity, scope or enforceability of or otherwise opposes any Patent included in the OncoMed IP or the OncoMed Platform Technology that is licensed to Celgene under this Agreement (other than as may be necessary or reasonably required to [***]) it being understood and agreed that OncoMed’s right to terminate this Agreement under this Section 11.5 shall not apply to [***]; provided that OncoMed’s right to terminate this Agreement under this Section 11.5 shall apply to such [***]. If a Sublicensee of Celgene challenges the validity, scope or enforceability of or otherwise opposes any Patent included in the OncoMed IP or the OncoMed Platform Technology under which such Sublicensee is sublicensed, then Celgene shall, upon written notice from OncoMed, terminate such sublicense. For the avoidance of doubt, an action [***], shall not constitute a challenge under this Section 11.5.

MISCELLANEOUS

12.1 Severability. If any one or more of the terms or provisions of this Agreement is held by a court of competent jurisdiction or arbitrator to be void, invalid or unenforceable in any situation in any jurisdiction, such holding shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the invalid, void or unenforceable term or provision in any other situation or in any other jurisdiction and the term or provision shall be considered severed from this Agreement, unless the invalid or unenforceable term or provision is of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid or unenforceable term or provision.

Any such counterpart, to the extent delivered by means of a fax machine or by .pdf, .tif, .gif, .jpeg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party hereto shall raise the use of Electronic Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery as a defense to the formation of a contract, and each Party forever waives any such defense, except to the extent that such defense relates to lack of authenticity.

12.11 Equitable Relief. Notwithstanding anything to the contrary herein, the Parties shall be entitled to seek equitable relief, including injunction and specific performance, as a remedy for any breach of this Agreement. Such remedies shall not be deemed to be the exclusive remedies for a breach of this Agreement but shall be in addition to all other remedies available at law or equity. The Parties further agree not to raise as a defense or objection to the request or granting of such relief that any breach of this Agreement is or would be compensable by an award of money damages.

12.12 Interpretation.

12.12.1 Generally. This Agreement has been diligently reviewed by and negotiated by and among the Parties, and in such negotiations each of them has been represented by competent counsel, and the final agreement contained herein, including the language whereby it has been expressed, represents the joint efforts of the Parties and their counsel. Accordingly, in interpreting this Agreement or any provision hereof, no presumption shall apply against any Party as being responsible for the wording or drafting of this Agreement or any such provision, and ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision.

RECITALS

WHEREAS, OncoMed, Celgene and Celgene Alpine entered into that certain Master Research and Collaboration Agreement, dated as of December 2, 2013 (the “Master Collaboration Agreement”), pursuant to which Celgene has an exclusive option to obtain an exclusive license to develop, manufacture and commercialize Product Candidates arising out of activities conducted pursuant to a Program (each, as defined in the Master Collaboration Agreement);

[***]

Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

WHEREAS, as a result of one of the foregoing circumstances with respect to a particular Licensed Program (as defined below), Celgene and OncoMed are obligated to enter into this License Agreement pursuant to which OncoMed grants to Celgene exclusive and worldwide rights with respect to the development, manufacture and commercialization of the Licensed Candidates (as defined below), and products containing such Licensed Candidates, on the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements set forth below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

ARTICLE 1

DEFINITIONS

Capitalized terms used, but not defined, herein will have the meanings ascribed to them in the Master Collaboration Agreement.

1.1 “Comparable License Third Party Product” means, on a Licensed Product-by-Licensed Product and country-by-country basis, any pharmaceutical or biological product (a) that contains (i) [***] such Licensed Product, or (ii) a [***], (b) for which [***], (c) is [***], or any other equivalent [***] in such country, and (d) is sold in the same country as such Licensed Product by [***].

1.2 “First License Sale” means, on a Licensed Product-by-Licensed Product and Diagnostic Product-by-Diagnostic Product basis, the first sale [***] by Celgene or its Affiliates or Sublicensees for use or consumption by the general public of such Licensed Product (or Diagnostic Product, as applicable) in the Territory for which all Regulatory Approvals that may be legally required in order to sell such Licensed Product (or Diagnostic Product, as applicable) in such country have been granted; in each case, provided, however, that the following shall not constitute a First License Sale: (a) any sale to an Affiliate or Sublicensee unless the Affiliate or Sublicensee is the last entity in the distribution chain of the Licensed Product (or Diagnostic Product, as applicable); (b) any use of such Licensed Product or Diagnostic Product in Clinical Trials, non-clinical development activities or other development activities with respect to such Licensed Product or Diagnostic Product by or on behalf of a Party, or disposal or transfer of such Licensed Product or Diagnostic Product for a bona fide charitable purpose; and (c) compassionate use, in each case for which no payment is received by Celgene, its Affiliates or Sublicensees.

1.3 “License Annual Net Sales” means, on a Licensed Product-by-Licensed Product and Diagnostic Product-by-Diagnostic Product basis, total License Net Sales by Celgene, its Affiliates and Sublicensees in the Territory of such Licensed Product in a particular Calendar Year.

1.4 “License Net Sales” means, with respect to any Licensed Product, the gross amounts invoiced by Celgene, its Affiliates and Sublicensees (each, a “License Selling Party”) to Third Party customers for sales of such Licensed Product, less the following deductions actually incurred, allowed, paid, accrued or specifically allocated in its financial statements in accordance with (as applicable to the License Selling Party) the Accounting Principles, for:

[***]

Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

(a) discounts (including trade, quantity and cash discounts) actually allowed, cash and non-cash coupons, retroactive price reductions, and charge-back payments and rebates granted to any Third Party (including to Governmental Authorities, purchasers, reimbursers, customers, distributors, wholesalers, and group purchasing and managed care organizations or entities (and other similar entities and institutions));

(b) credits or allowances, if any, on account of price adjustments, recalls, claims, damaged goods, rejections or returns of items previously sold (including Licensed Product returned in connection with recalls or withdrawals) and amounts written off by reason of uncollectible debt; provided, that if the debt is thereafter paid, the corresponding amount shall be added to the License Net Sales of the period during which it is paid;

(c) rebates (or their equivalent), administrative fees, chargebacks and retroactive price adjustments and any other similar allowances granted by a License Selling Party (including to Governmental Authorities, purchasers, reimbursers, customers, distributors, wholesalers, and group purchasing and managed care organizations and entities (and other equivalent entities and institutions)) which effectively reduce the selling price or gross sales of the Licensed Product, as well as costs of distribution and wholesale;

(d) insurance, customs charges, freight, postage, shipping, handling, and other transportation costs incurred by a License Selling Party in shipping Licensed Product to a Third Party;

(e) import taxes, export taxes, excise taxes (including annual fees due under Section 9008 of the United States Patient Protection and Affordable Care Act of 2010 (Pub. L. No. 111-48) and other comparable Laws), sales tax, value-added taxes, consumption taxes, duties or other taxes levied on, absorbed, determined and/or imposed with respect to such sales (excluding income or net profit taxes or franchise taxes of any kind); and

(f) reasonable discounts due to factoring of receivables that are incurred consistent with its other pharmaceutical products of like character in a given country.

If non-monetary consideration is received by a License Selling Party for any Licensed Product in the relevant country, License Net Sales will be calculated based on the average price charged for such Licensed Product, as applicable, during the preceding royalty period, or in the absence of such sales, the fair market value of the Licensed Product, as applicable, as determined by the Parties in good faith. Notwithstanding the foregoing, License Net Sales shall not be imputed to transfers of Licensed Products, as applicable, for use in Clinical Trials, non-clinical development activities or other development activities with respect to Licensed Products by or on behalf of the Parties, for bona fide charitable purposes or for compassionate use or for Licensed Product samples, if no monetary consideration is received for such transfers.

License Net Sales shall be determined on, and only on, the first sale by Celgene or any of its Affiliates or Sublicensees to a non-Sublicensee Third Party.

If a Licensed Product is sold as part of a License Combination Product (as defined below), License Net Sales will be the product of (i) License Net Sales of the License Combination Product calculated as above (i.e., calculated as for a non-License Combination Product) and (ii) the fraction (A/(A+B)), where:

“A” is the gross invoice price in such country of the Licensed Product comprising a Lead Candidate as the sole therapeutically active ingredient; and

“B” is the gross invoice price in such country of the other therapeutically active ingredients contained in the License Combination Product.

If “A” or “B” cannot be determined by reference to non-License Combination Product sales as described above, then License Net Sales will be calculated as above, but the gross invoice price in the above equation shall be determined by mutual agreement reached in good faith by the Parties prior to the end of the accounting period in question based on an equitable method of determining the same that takes into account, in the applicable country, variation in dosage units and the relative fair market value of each therapeutically active ingredient in the License Combination Product.

As used in this definition of “License Net Sales,” “License Combination Product” means a Licensed Product that contains one or more additional active ingredients (whether co-formulated or co-packaged) that are neither Licensed Candidates nor generic or other non-proprietary compositions of matter. Pharmaceutical dosage form vehicles, adjuvants and excipients shall be deemed not to be “active ingredients.” For clarity, solely for the purposes of determining what constitutes License Annual Net Sales of Diagnostic Products, and for no other purpose, the foregoing definition of License Net Sales will apply to sales of Diagnostic Products as if such Diagnostic Products were Licensed Products.

1.5 “License Regulatory-Based Exclusivity” means, on a Licensed Product-by-Licensed Product and country-by-country basis, that (a) Celgene or any of its Affiliates or Sublicensees has been granted the exclusive legal right by a Regulatory Authority (or is otherwise entitled to the exclusive legal right by operation of Law) in such country to market and sell the Licensed Product or the active ingredient comprising such Licensed Product in such country, or (b) the data and information submitted by Celgene or any of its Affiliates or Sublicensees to the relevant Regulatory Authority in such country for purposes of obtaining Regulatory Approval may not be disclosed, referenced or relied upon in any way by any Person other than Celgene, its Affiliates or Sublicensees (including by relying upon the Regulatory Authority’s previous findings regarding the safety or effectiveness of the Licensed Product) to support the Regulatory Approval or marketing of any product by a Third Party in such country.

1.6 “License Royalty Term” means, on a Licensed Product-by-Licensed Product and country-by-country basis, the period of time commencing on the First License Sale of such Licensed Product in such country and expiring upon the latest of (a) the expiration of the last Valid Claim of [***] of such Licensed Product in such country, (b) the expiration of License Regulatory-Based Exclusivity of such Licensed Product in such country, and (c) the [***] anniversary of the date of First License Sale of such Licensed Product in such country. “License

[***]

Royalty Term” means, with respect to Diagnostic Products related to Licensed Products, on a Diagnostic Product-by-Diagnostic Product and country-by-country basis, the period of time commencing on the First License Sale of such Diagnostic Product in such country and expiring upon the latest of (x) the expiration of the last Valid Claim of [***] of such Diagnostic Product in such country, and (y) the [***] anniversary of the date of First License Sale of such Diagnostic Product in such country.

1.7 “Manufacturing Transition Costs” means the [***] costs associated with the transfer by OncoMed, following the License Agreement Effective Date, of responsibility for Manufacturing and CMC Activities to Celgene or a Third Party, including [***], and [***] in relation to such transfer. Manufacturing Transition Costs shall [***].

1.8 “OncoMed Licensed IP” means, with respect to the Licensed Program, (a) all OncoMed IP Controlled by OncoMed and/or its Affiliates as of the License Agreement Effective Date or at any time thereafter during the License Term that is (i) [***] or (ii) [***], (b) OncoMed’s interest in Joint Collaboration IP, and (c) OncoMed’s interest in [***]. The Patents set forth on Schedule 7.11 are included in the OncoMed Licensed IP. Notwithstanding anything to the contrary in this Section 1.8 or on Schedule 7.11, Patents included in the OncoMed Licensed IP shall not include (A) any Patents to the extent such Patents [***], or (B) any Patents to the extent such Patents [***], unless and until [***] for the Licensed Program (to the extent such Licensed Program was the subject of a Co-Development and Co-Commercialization Agreement previously).

7.5.2 Enforcement of OncoMed Licensed Patents and Celgene Patents.

(a) Initial Enforcement. As between the Parties, and subject to Sections 7.7 and 7.8:

(i) Celgene shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to any License Competitive Infringement of (A) any [***] under this License Agreement that [***] (such Patents, the “OncoMed Licensed Product Patents”), and (B) any Celgene Patent or any Collaboration Patent [***] pursuant to the terms of the Master Collaboration Agreement (the “Celgene Licensed Patents”), in each case by counsel of its own choice, in Celgene’s own name and under Celgene’s direction and control. The foregoing right of Celgene shall include the right to perform all actions of a reference product sponsor set forth in the U.S. ▇▇▇▇▇-▇▇▇▇▇▇ Act or Public Health Service Act, and any ex-U.S. equivalent of the ▇▇▇▇▇-▇▇▇▇▇▇ Act (the “▇▇▇▇▇-▇▇▇▇▇▇ Act”).

(ii) OncoMed shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to any License Competitive Infringement of any OncoMed Licensed Patent that is exclusively licensed to Celgene under this License Agreement that is not an OncoMed Licensed Product Patent, by counsel of its own choice, in OncoMed’s own name and under OncoMed’s direction and control, provided that with respect to enforcement in relation to Licensed Product, OncoMed shall keep Celgene, through the JSC, reasonably informed as to the status of, and all material developments in such action, and shall consider in good faith the input of Celgene regarding the strategy and handling of such enforcement activities. The foregoing right of OncoMed shall include the right to perform all actions of a reference product sponsor set forth in the ▇▇▇▇▇-▇▇▇▇▇▇ Act to the extent permitted under applicable Law, and if OncoMed is limited in performing such actions, Celgene shall reasonably cooperate to enable OncoMed to perform such actions.

(b) Timing. The Party with the first right to institute, prosecute, and control any action or proceeding with respect to any License Competitive Infringement described in Section 7.5.2(a) (a “License Enforcement Proceeding”) will have a period of [***] after its receipt or delivery of notice and evidence pursuant to Section 7.5.1 or receipt of written notice from a Third Party that reasonably evidences License Competitive Infringement, to elect to so enforce such OncoMed Licensed Patent or Celgene Licensed Patent (other than a Celgene Background Patent) in the applicable jurisdiction (or to settle or otherwise secure the abatement

[***]

of such License Competitive Infringement), provided however, that such period will be (i) more than [***] to the extent applicable Law prevents earlier enforcement of such OncoMed Licensed Patent or Celgene Licensed Patent (such as the enforcement process set forth in or under the ▇▇▇▇▇-▇▇▇▇▇▇ Act), and provided further that if such period is extended because applicable Law prevents earlier enforcement, the enforcing Party shall have until the date that is [***] following the date upon which applicable Law first permits such License Enforcement Proceeding, and (ii) less than [***] to the extent that a delay in bringing such License Enforcement Proceeding against such alleged Third Party infringer would limit or compromise the remedies (including monetary relief, and stay of regulatory approval) available against such alleged Third Party infringer. In the event the enforcing Party does not so elect (or settle or otherwise secure the abatement of such License Competitive Infringement) before the first to occur of (A) the expiration of the applicable period of time set forth in the preceding subsections (i) and (ii), or (B) [***] before the expiration of any time period under applicable Law, that would, if a License Enforcement Proceeding was not filed within such time period, limit or compromise the remedies available from such License Enforcement Proceeding, it will so notify the other Party in writing and in the case where such other Party then desires to commence a suit or take action to enforce the applicable OncoMed Licensed Patent or Celgene Licensed Patent (excluding any Celgene Background Patent) with respect to such License Competitive Infringement in the applicable jurisdiction, such other Party will thereafter have the right to commence such a suit or take such action to enforce the applicable OncoMed Licensed Patent or Celgene Licensed Patent (excluding any Celgene Background Patent), as applicable (such action, a “License Step-In Proceeding”), at such other Party’s expense.

(c) Right to Participate; Joinder. The non-enforcing Party in relation to any enforcement action or proceeding set forth in Section 7.5.2(a) will have the right, at its own expense and by counsel of its choice, to be represented in any such action or proceeding. In the case of any License Enforcement Proceeding or License Step-In Proceeding, at the enforcing Party’s written request, and at the enforcing Party’s expense (subject to Section 7.5.4), the other Party will join any such action or proceeding as a party and will use Commercially Reasonable Efforts to cause any Third Party as necessary to join such action or proceeding as a party if doing so is necessary for the purposes of establishing standing or is otherwise required by applicable Law to pursue such action or proceeding. All time periods set forth in Section 7.5.2(b) shall be subject to applicable Law, which may prevent earlier enforcement.

(d) Cooperation. In addition to the obligations set forth in Sections 7.5.2(a) and 7.5.2(c), each Party will provide to the Party enforcing any such rights under Section 7.5.2(a) reasonable assistance and cooperation in such enforcement, at such enforcing Party’s request and expense. The enforcing Party will keep the other Party regularly informed of the status and progress of such enforcement efforts. The Parties will coordinate any License Enforcement Proceeding with respect to the OncoMed Licensed Patents or Celgene Licensed Patents (other than Celgene Background Patents) through the JSC. Each Party bringing any such action or proceeding in accordance with this Section 7.5 shall have an obligation to consult with the other Party and will take comments of such other Party into good faith consideration with respect to the infringement, claim construction, or defense of the validity or enforceability of any claim in any OncoMed Licensed Patent or Celgene Patent that is the subject of such proceeding, provided that the foregoing shall not apply to any such action or proceeding relating to the Celgene Background Patents, which Celgene may conduct at its sole discretion.

(a) Initial Allocation.

If such recovery is insufficient to cover all such costs and expenses of both Parties, it shall be [***]; and

(b) Remaining Proceeds. Any remaining proceeds shall, in case of suits with respect to a License Enforcement Proceeding or a License Step-In Proceeding relating to any Licensed Product or related Diagnostic Product under Section 7.5, be allocated between the Parties such that [***] and the [***] of such amount.

7.6 Patent Term Extensions.

Any exclusive licenses that are granted under this License Agreement that constitute sublicenses under the Existing Agreements are exclusive only to the extent of the exclusive nature of the license granted to OncoMed under the Existing Agreements.

8.2 Michigan Agreement. Without limiting Section 8.1:

(a) Reservation of Rights. Celgene acknowledges that the University of Michigan reserves the right to: (i) practice the Michigan Patents for internal academic research, non-revenue producing public service, and, internal educational (including clinical trials) purposes; and, (ii) grant a Limited Research License (as such term is defined in the Michigan Agreement) to other non-profit research institutions.

CO-DEVELOPMENT AND CO-COMMERCIALIZATION AGREEMENT

This CO-DEVELOPMENT AND CO-COMMERCIALIZATION AGREEMENT (this “Co-Co Agreement”) is entered into and made effective as of [•], 20 (the “Co-Co Agreement Effective Date”) by and between OncoMed Pharmaceuticals, Inc., a Delaware corporation (“OncoMed”), and Celgene Corporation, a Delaware corporation (“Celgene Corp.”), with respect to all rights and obligations under this Co-Co Agreement in the United States (subject to Section 11.6), and Celgene Alpine Investment Company II, LLC, a Delaware limited liability company (“Celgene Alpine”), with respect to all rights and obligations under this Agreement outside of the United States (subject to Section 11.6) (Celgene Alpine and Celgene Corp., together, “Celgene”). Celgene and OncoMed are each referred to herein by name or as a “Party” or, collectively, as the “Parties.”

RECITALS

WHEREAS, pursuant to the terms of the Master Collaboration Agreement, upon exercise by Celgene of its option with respect to a Program (other than [***]) (each, as defined in the Master Collaboration Agreement), the Parties shall enter into a co-development and co-commercialization agreement with respect to such Program; and

WHEREAS, Celgene has exercised its Option with respect to such Program and has elected to obtain from OncoMed, and OncoMed has agreed to grant to Celgene, exclusive and worldwide rights with respect to the Development, Manufacture and Commercialization of the Co-Co Candidates (each, as defined below), and products containing such Co-Co Candidates, on the terms and subject to the conditions set forth herein, including that commercialization in the U.S. shall be co-exclusive with OncoMed.

ARTICLE 1

DEFINITIONS

Capitalized terms used, but not defined, herein will have the meanings ascribed to them in the Master Collaboration Agreement.

1.1 “Co-Co Annual Net Sales” means, on a Co-Co Product-by-Co-Co Product and Diagnostic Product-by-Diagnostic Product basis, total Co-Co Net Sales by Celgene, its Affiliates and Sublicensees in the ROW of such Co-Co Product in a particular Calendar Year.

[***]

Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

1.2 “Co-Co Net Sales” means, with respect to any Co-Co Product, the gross amounts invoiced by Celgene, its Affiliates and Sublicensees (to the extent invoiced for sales of Co-Co Products in ROW) (each, a “Co-Co Selling Party”) to Third Party customers for sales of such Co-Co Product, less the following deductions actually incurred, allowed, paid, accrued or specifically allocated in its financial statements in accordance with (as applicable to the Co-Co Selling Party) the Accounting Principles, for:

(b) credits or allowances, if any, on account of price adjustments, recalls, claims, damaged goods, rejections or returns of items previously sold (including Co-Co Product returned in connection with recalls or withdrawals) and amounts written off by reason of uncollectible debt; provided, that if the debt is thereafter paid, the corresponding amount shall be added to the Co-Co Net Sales of the period during which it is paid;

(c) rebates (or their equivalent), administrative fees, chargebacks and retroactive price adjustments and any other similar allowances granted by a Co-Co Selling Party (including to Governmental Authorities, purchasers, reimbursers, customers, distributors, wholesalers, and group purchasing and managed care organizations and entities (and other equivalent entities and institutions)) which effectively reduce the selling price or gross sales of the Co-Co Product, as well as costs of distribution and wholesale;

(d) insurance, customs charges, freight, postage, shipping, handling, and other transportation costs incurred by a Co-Co Selling Party in shipping Co-Co Product to a Third Party;

(f) reasonable discounts due to factoring of receivables that are incurred consistent with its other pharmaceutical products of like character in a given country.

If non-monetary consideration is received by a Co-Co Selling Party for any Co-Co Product in the relevant country, Co-Co Net Sales will be calculated based on the average price charged for such Co-Co Product, as applicable, during the preceding royalty period, or in the absence of such sales, the fair market value of the Co-Co Product, as applicable, as determined by the Parties in good faith. Notwithstanding the foregoing, Co-Co Net Sales shall not be imputed to transfers of Co-Co Products, as applicable, for use in Clinical Trials, non-clinical development activities or other development activities with respect to Co-Co Products by or on behalf of the Parties, for bona fide charitable purposes or for compassionate use or for Co-Co Product samples, if no monetary consideration is received for such transfers.

[***]

Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

Co-Co Net Sales shall be determined on, and only on, the first sale by Celgene or any of its Affiliates or Sublicensees to a non-Sublicensee Third Party.

If a Co-Co Product is sold as part of a Co-Co Combination Product (as defined below), Co-Co Net Sales will be the product of (i) Co-Co Net Sales of the Co-Co Combination Product calculated as above (i.e., calculated as for a non-Co-Co Combination Product) and (ii) the fraction (A/(A+B)), where:

“A” is the gross invoice price in such country of the Co-Co Product comprising a Co-Co Candidate as the sole therapeutically active ingredient; and

“B” is the gross invoice price in such country of the other therapeutically active ingredients contained in the Co-Co Combination Product.

If “A” or “B” cannot be determined by reference to non-Co-Co Combination Product sales as described above, then Co-Co Net Sales will be calculated as above, but the gross invoice price in the above equation shall be determined by mutual agreement reached in good faith by the Parties prior to the end of the accounting period in question based on an equitable method of determining the same that takes into account, in the applicable country, variation in dosage units and the relative fair market value of each therapeutically active ingredient in the Co-Co Combination Product.

As used in this definition of “Co-Co Net Sales,” “Co-Co Combination Product” means a Co-Co Product that contains one or more additional active ingredients (whether co-formulated or co-packaged) that are neither Co-Co Candidates nor generic or other non-proprietary compositions of matter. Pharmaceutical dosage form vehicles, adjuvants and excipients shall be deemed not to be “active ingredients.” For clarity, solely for the purposes of determining what constitutes Co-Co Annual Net Sales of Diagnostic Products, and for no other purpose, the foregoing definition of Co-Co Net Sales will apply to sales of Diagnostic Products as if such Diagnostic Products were Co-Co Products.

1.3 “Co-Co Regulatory-Based Exclusivity” means, on a Co-Co Product-by-Co-Co Product and country-by-country basis, that (a) Celgene or any of its Affiliates or Sublicensees has been granted the exclusive legal right by a Regulatory Authority (or is otherwise entitled to the exclusive legal right by operation of Law) in such country to market and sell the Co-Co Product or the active ingredient comprising such Co-Co Product in such country, or (b) the data and information submitted by Celgene or any of its Affiliates or Sublicensees to the relevant Regulatory Authority in such country for purposes of obtaining Regulatory Approval may not be disclosed, referenced or relied upon in any way by any Person other than Celgene, its Affiliates or Sublicensees (including by relying upon the Regulatory Authority’s previous findings regarding the safety or effectiveness of the Co-Co Product) to support the Regulatory Approval or marketing of any product by a Third Party in such country.

[***]

Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

1.4 “Co-Co Royalty Term” means, on a Co-Co Product-by-Co-Co Product and country-by-country basis, the period of time commencing on the First Co-Co Sale of such Co-Co Product in such country and expiring upon the latest of (a) the expiration of the last Valid Claim of [***] of such Co-Co Product in such country, (b) the expiration of Co-Co Regulatory-Based Exclusivity of such Co-Co Product in such country, and (c) the [***] anniversary of the date of First Co-Co Sale of such Co-Co Product in such country. “Co-Co Royalty Term” means, with respect to Diagnostic Products related to Co-Co Products, on a Diagnostic Product-by-Diagnostic Product and country-by-country basis, the period of time commencing on the First Co-Co Sale of such Diagnostic Product in such country and expiring upon the latest of (x) the expiration of the last Valid Claim of [***] of such Diagnostic Product in such country, and (y) the [***] anniversary of the date of First Co-Co Sale of such Diagnostic Product in such country.

1.5 “Comparable Co-Co Third Party Product” means, on a Co-Co Product-by-Co-Co Product and country-by-country basis, any pharmaceutical or biological product (a) that contains (i) [***] such Co-Co Product, or (ii) a [***], (b) for which [***], (c) is [***] or any other equivalent [***] in such country, and (d) is sold in the same country as such Co-Co Product by [***].

The Party with the first right to institute, prosecute, and control any action or proceeding with respect to any Competitive Infringement described in Section 7.5.2(a), 7.5.2(b) or 7.5.2(c) (each, a “Co-Co Enforcement Proceeding”) will have a period of [***] after its receipt or delivery of notice and evidence pursuant to Section 7.5.1 or receipt of written notice from a Third Party that reasonably evidences Competitive Infringement, to elect to so enforce such OncoMed Co-Co Patent or Celgene Co-Co Patent (other than a Celgene Background Patent) in the applicable jurisdiction (or to settle or otherwise secure the abatement of such Competitive Infringement), provided however, that such period will be (i) more than [***] to the extent applicable Law prevents earlier enforcement of such OncoMed Co-Co Patent or Celgene Co-Co Patent (such as the enforcement process set forth in or under the ▇▇▇▇▇-▇▇▇▇▇▇ Act), and provided further that if such period is extended because applicable Law prevents earlier enforcement, the enforcing Party shall have until the date that is [***] following the date upon which applicable Law first permits such Co-Co Enforcement Proceeding, and (ii) less than [***] to the extent that a delay in bringing such Co-Co Enforcement Proceeding against such alleged Third Party infringer would limit or compromise the remedies (including monetary relief, and stay of regulatory approval) available against such alleged Third Party infringer. In the event the enforcing Party does not so elect (or settle or otherwise secure the abatement of such Competitive Infringement) before the first to occur of (A) expiration of the applicable period of time set forth in the preceding subsections (i) and (ii), or (B) [***] before the expiration of any time period under applicable Law that would, if an Co-Co Enforcement Proceeding was not filed within such time period, limit or compromise the remedies available from such Co-Co Enforcement Proceeding, it will so notify the other Party in writing and in the case where such other Party then desires to commence a suit or take action to enforce the applicable OncoMed Co-Co Patent or Celgene Co-Co Patent (excluding any Celgene Background Patent) with respect to such Competitive Infringement in the applicable jurisdiction, such other Party will thereafter have the right to commence such a suit or take such action to enforce the applicable OncoMed Co-Co Patent or Celgene Co-Co Patent (excluding any Celgene Background Patent), as applicable (such action, a “Co-Co Step-In Proceeding”), at such other Party’s expense.

(e) Right to Participate; Joinder. The non-enforcing Party in relation to any enforcement action or proceeding set forth in Sections 7.5.2(a) through 7.5.2(c) will have the right, at its own expense and by counsel of its choice, to be represented in any such action or proceeding. In the case of any Co-Co Enforcement Proceeding or Co-Co Step-In Proceeding, at the enforcing Party’s written request, and at the enforcing Party’s expense (subject to Section 7.5.4), the other Party will join any such action or proceeding as a party and will use Commercially Reasonable Efforts to cause any Third Party as necessary to join such action or proceeding as a party if doing so is necessary for the purposes of establishing standing or is otherwise required by applicable Law to pursue such action or proceeding, or if the JSC (with respect to enforcement activities relating to Co-Co Product for U.S. Administration) determines that such joinder is necessary or desirable. All time periods set forth in this Section 7.5.2 shall be subject to applicable Law, which may prevent earlier enforcement.

The enforcing Party will keep the other Party regularly informed of the status and progress of such enforcement efforts. The Parties will coordinate any Co-Co Enforcement Proceeding with respect to the OncoMed Co-Co Patents or Celgene Co-Co Patents (other than Celgene Background Patents) through the JSC. Each Party bringing any such action or proceeding in accordance with this Section 7.5 shall have an obligation to consult with the other Party and will take comments of such other Party into good faith consideration with respect to the infringement, claim construction, or defense of the validity or enforceability of any claim in any OncoMed Co-Co Patent or Celgene Co-Co Patent that is the subject of such proceeding, provided that the foregoing shall not apply to any such action or proceeding relating to the Celgene Background Patents, which Celgene may conduct at its sole discretion.

(ii) OncoMed does not have the right to enforce the Patents licensed to OncoMed pursuant to the MorphoSys Agreement; and

notwithstanding the foregoing subsections (i) through (iii), each Party’s rights to enforce an OncoMed Co-Co Patent pursuant to this Section 7.5, or to defend against a challenge in any action or proceeding described in Section 7.4, shall be subject to the applicable provisions of any agreements between the OncoMed and its licensor.

of such sales, the fair market value of the [***]SM Product, as applicable, as determined by the Parties in good faith. Notwithstanding the foregoing, [***]SM Net Sales shall not be imputed to transfers of [***]SM Products, as applicable, for use in Clinical Trials, non-clinical development activities or other development activities with respect to [***]SM Products by or on behalf of the Parties, for bona fide charitable purposes or for compassionate use or for [***]SM Product samples, if no monetary consideration is received for such transfers.

[***]SM Net Sales shall be determined on, and only on, the first sale by Celgene or any of its Affiliates or Sublicensees to a non-Sublicensee Third Party.

If a [***]SM Product is sold as part of a [***]SM Combination Product (as defined below), [***]SM Net Sales will be the product of (i) [***]SM Net Sales of the [***]SM Combination Product calculated as above (i.e., calculated as for a non-[***]SM Combination Product) and (ii) the fraction (A/(A+B)), where:

“A” is the gross invoice price in such country of the [***]SM Product comprising a [***]SM Program Compound as the sole therapeutically active ingredient; and

“B” is the gross invoice price in such country of the other therapeutically active ingredients contained in the [***]SM Combination Product.

If “A” or “B” cannot be determined by reference to non-[***]SM Combination Product sales as described above, then [***]SM Net Sales will be calculated as above, but the gross invoice price in the above equation shall be determined by mutual agreement reached in good faith by the Parties prior to the end of the accounting period in question based on an equitable method of determining the same that takes into account, in the applicable country, variation in dosage units and the relative fair market value of each therapeutically active ingredient in the [***]SM Combination Product.

As used in this definition of “[***]SM Net Sales,” “[***]SM Combination Product” means a [***]SM Product that contains one or more additional active ingredients (whether co-formulated or co-packaged) that are neither [***]SM Program Compounds nor generic or other non-proprietary compositions of matter. Pharmaceutical dosage form vehicles, adjuvants and excipients shall be deemed not to be “active ingredients.” For clarity, solely for the purposes of determining what constitutes Annual [***]SM Net Sales of Diagnostic Products, and for no other purpose, the foregoing definition of [***]SM Net Sales will apply to sales of Diagnostic Products as if such Diagnostic Products were [***]SM Products.

1.14 “[***]SM OncoMed Assays” means any OncoMed Assay Technology that OncoMed provides to Celgene pursuant to Section 2.12.

1.15 “[***]SM Regulatory-Based Exclusivity” means, on a [***]SM Product-by-[***]SM Product and country-by-country basis, that (a) Celgene or any of its Affiliates or Sublicensees has been granted the [***] in such country to market and sell the [***]SM Product, or the applicable [***]SM Program Compound as the active ingredient comprising such [***]SM Product in such country, or (b) the [***] in such country for purposes of obtaining Regulatory Approval [***] of any product by a Third Party in such country.

1.16 “[***]SM Research Plan” means the research plan governing the initial research activities to be conducted by the Parties in furtherance of the [***]SM Program pursuant to this [***]SM Agreement, attached hereto as Exhibit B, which may be amended from time to time by the JSC pursuant to Section 2.10.1(b).

1.17 “[***]SM Royalty Term” means, on a [***]SM Product-by-[***]SM Product and country-by-country basis, the period of time commencing on the First [***]SM Sale of such [***]SM Product in such country and expiring upon the latest of (a) the expiration of the last Valid Claim of any [***] or [***], (b) the expiration of Regulatory-Based Exclusivity of such [***]SM Product in such country, and (c) the [***] anniversary of the date of First [***]SM Sale of such [***]SM Product in such country. “[***]SM Royalty Term” means, with respect to Diagnostic Products related to [***]SM Products, on a Diagnostic Product-by-Diagnostic Product and country-by-country basis, the period of time commencing on the First [***]SM Sale of such Diagnostic Product in such country and expiring upon the latest of (x) the expiration of the last Valid Claim of any [***], and (y) the [***] anniversary of the date of First [***]SM Sale of such Diagnostic Product in such country.

1.18 “[***]SM Selected Target” means a [***]SM Target that is selected by Celgene, for further research and development, including the identification and further development of [***]SM Program Compounds with respect to such [***]SM Target, in accordance with the [***]SM Research Plan.

(a) Initial Enforcement. As between the Parties, and subject to Section 7.7 and Section 7.8:

(i) Celgene shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to any [***]SM Competitive Infringement of (A) any [***] under this [***]SM Agreement and that [***] (such Patents, the “OncoMed [***]SM Product Patents”), and (B) any [***] pursuant to the terms of the Master Collaboration Agreement (the “Celgene [***]SM Patents”), in each case by counsel of its own choice, in Celgene’s own name and under Celgene’s direction and control.

Press Release

OncoMed and Celgene Announce Strategic Collaboration Advancing Multiple Anti-Cancer Stem Cell Therapeutics to Offer Potential Benefits to Cancer Patients

Celgene Invests in OncoMed’s Demcizumab and Up to Five Additional Preclinical Biologics Programs; OncoMed Leads Early Clinical Trials and Retains Co-Development, Co-Commercialization and Profit Sharing Rights

OncoMed to Receive $177.25 Million Upfront, Including a $22.25 Million Equity Investment

OncoMed to Host a Conference Call this Morning for Investors at 8:30 a.m. ET

REDWOOD CITY, Calif., Dec. 3, 2013 — OncoMed Pharmaceuticals, Inc. (Nasdaq:OMED) and Celgene Corporation (Nasdaq:CELG) today announced an agreement to jointly develop and commercialize up to six anti-cancer stem cell (CSC) product candidates from OncoMed’s biologics pipeline, including demcizumab (OMP-21M18, Anti-DLL4).

OncoMed will control and conduct initial clinical studies at which point Celgene has an option to license worldwide rights to up to six novel anti-CSC therapeutic candidates. OncoMed retains global co-development and U.S. co-commercialization rights for five of the six anti-CSC product candidates with 50/50 U.S. profit sharing, and royalties to be received in other territories. Celgene will also have research, development and commercialization rights to small molecule compounds in an undisclosed cancer stem cell pathway.

Celgene obtains an exclusive option on one of OncoMed’s most advanced clinical candidates, demcizumab, during or after the completion of certain future planned Phase II clinical trials to be conducted by OncoMed. Demcizumab is currently in three Phase Ib clinical studies in combination with standard-of-care therapeutics, including a trial in patients with first-line advanced pancreatic cancer. Subsequent to option exercise, the parties will co-develop demcizumab, sharing global development costs on a 1/3 OncoMed and 2/3 Celgene basis. The companies will co-commercialize demcizumab in the United States with 50/50 profit sharing. Outside the United States, Celgene would lead development and commercialization, with OncoMed eligible to receive milestones and tiered double-digit royalties on sales outside the United States.

In addition to demcizumab, the collaboration includes up to five preclinical- or discovery-stage biologics programs: OncoMed’s anti-DLL4/VEGF bispecific antibody and up to four additional biologics programs targeting either the RSPO-LGR CSC pathway or an additional undisclosed CSC pathway. Celgene obtains exclusive options on these programs during or after completion of certain Phase I clinical trials to be conducted by OncoMed. For the anti-DLL4/VEGF bispecific antibody and three of the four additional biologics programs, OncoMed retains 50/50 U.S. profit sharing and co-commercialization terms, plus 1/3 OncoMed and 2/3 Celgene global development cost-

I - 1

sharing and mid-single digit to mid-double digit royalties outside the profit-sharing territory. On the fourth biologics program, Celgene would receive an exclusive worldwide license, with OncoMed receiving high-single digit to mid-double digit royalties on worldwide sales. Celgene also obtains an option to conduct small molecule research, development, and commercialization in an undisclosed CSC pathway, with OncoMed eligible to receive milestones and low- to mid-single digit royalties on any resulting small molecule anti-cancer product candidates.

Under the terms of the agreement, OncoMed will receive an upfront payment of $155 million, and Celgene will also purchase approximately $22.25 million in a private placement of newly issued shares of OncoMed’s common stock at a price of $15.13 per share.

The collaboration also includes option exercise payments and payments for achievement of development, regulatory and commercial milestones, paid on a per-program basis. For demcizumab, these payments could total up to approximately $790 million, and include an undisclosed payment for achievement of pre-determined safety criteria in Phase II clinical trials. For the anti-DLL4/VEGF bispecific antibody, option exercise, development, regulatory and commercial payments could total up to $505 million. For the other four biologics, each program is eligible for approximately $440 million of option exercise, development, regulatory and commercial payments. OncoMed could also receive more than $100 million in option exercise, development and regulatory approval payments for the small molecule program. Such total payments include milestones for regulatory approvals in multiple indications per program. OncoMed retains worldwide rights to certain targets in multiple pathways that do not become collaboration programs with Celgene.

“Through this major alliance with Celgene, we gain substantial resources that will enable us to continue to discover and develop new therapeutics independently while positioning OncoMed for substantial potential downstream value and profits. Importantly, by retaining co-development and co-commercialization rights to up to five biologic product candidates in our pipeline, we expect to add commercial capabilities to our core research and development competencies as we continue to build a premier oncology biotherapeutics company,” said ▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, OncoMed’s Chairman and CEO. “Celgene is a preeminent biopharmaceutical innovator with a successful track record of translating unique science into disease-altering therapies that benefit patients, healthcare and society. We can greatly benefit from their expertise and look forward to many years of successful collaboration.”

▇▇▇ ▇▇▇▇▇▇, President, Global Research & Early Development, of Celgene said, “We are very pleased to enter into this broad based collaboration with OncoMed, one that holds great promise for cancer patients. Demcizumab’s substantial early clinical activity warrants aggressive yet careful evaluation in several indications where we have strength, including non-small cell lung cancer and pancreatic cancer. The earlier partnerships in the RSPO-LGR and another, undisclosed cancer stem cell pathway provide us complementary and strategically valuable targeting opportunities across both biologic and small molecule modalities in the cancer stem cell arena where OncoMed has provided leadership and great strength.”

▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP and Leerink ▇▇▇▇▇ LLC acted as advisors to OncoMed for this transaction.

About Cancer Stem Cells

Cancer stem cells, or CSCs, are the subpopulation of cells in a tumor responsible for driving growth and metastasis of the tumor. CSCs, also known as tumor-initiating cells, exhibit certain properties which include the capacity to divide and give rise to new CSCs via a process called self-renewal and the capacity to differentiate or change into the other cells that form the bulk of the tumor. Common cancer drugs target bulk tumor cells but have limited impact on CSCs, thereby providing a path for recurrence of the tumor. OncoMed has advanced five distinct anti-CSC targeting product candidates into clinical trials, including demcizumab (OMP-21M18). OncoMed believes its product candidates are distinct from the current generations of chemotherapies and targeted therapies, and have the potential to significantly impact cancer treatment and the clinical outcome of patients with cancer.

About Demcizumab (OMP-21M18)

Demcizumab is a humanized monoclonal antibody that inhibits Delta-Like Ligand 4 (DLL4) in the Notch signaling pathway. Two Phase Ib combination trials of demcizumab are ongoing: demcizumab with standard-of-care in first-line advanced pancreatic cancer patients, and demcizumab with standard-of-care carboplatin and pemetrexed (Alimta™) in first-line advanced non-small cell lung cancer (NSCLC) patients. In addition, a Phase Ib/II trial of demcizumab and paclitaxel in patients with platinum-resistant ovarian cancer is ongoing at MD ▇▇▇▇▇▇▇▇ Cancer Center. Demcizumab is part of OncoMed’s collaboration with Celgene Corporation.

About OncoMed Pharmaceuticals

OncoMed Pharmaceuticals is a clinical-stage company focused on discovering and developing novel therapeutics targeting cancer stem cells. OncoMed has five anti-cancer product candidates in clinical development, including demcizumab (Anti-DLL4, ▇▇▇-▇▇▇▇▇), ▇▇▇-▇▇▇▇ (Anti-Notch2/3), OMP-52M51 (Anti-Notch1), vantictumab (Anti-Fzd7, OMP-18R5), and OMP-54F28 (Fzd8-Fc), which target key cancer stem cell signaling pathways including Notch and Wnt. OncoMed has two other antibodies in preclinical development, Anti-DLL4/Anti-VEGF bispecific and Anti-RSPO3, with Investigational New Drug filings planned for as early as 2014. OncoMed is also

All remaining portions will remain in full force and effect as if the original Agreement had been executed without the invalidated, unenforceable, or illegal part.

15. Any notices [or payments] required or permitted hereunder shall be given to the appropriate party at the address specified above or at such other address as the party shall specify in writing. Such notice shall be deemed given upon personal delivery, or four (4) days after the date of mailing when sent by certified or registered mail, postage prepaid, or upon the day sent by facsimile (subject to electronically confirmed delivery).

16. The parties shall perform their obligations under this Agreement as independent contractors and nothing contained herein shall be construed to be inconsistent with such relationship or status. This Agreement shall not constitute, create or in any way be interpreted as a joint venture or partnership of any kind.
