 2.4.4 Substitute Compounds. Within [***] after selection by the JSC of a Candidate
Selection Compound pursuant to Section 2.4.2 or 2.4.3, the JSC shall determine whether such Candidate Selection Compound shall be deemed a compound that may be substituted as a backup compound at a later time for any previously selected
Candidate Selection Compound that binds to and/or directly modulates the same Collaboration Target if, based on properties of the previously selected Candidate Selection Compound, the previously selected Candidate Selection Compound Development is
terminated and the newly identified Candidate Selection Compound may possess improved properties more suitable for Development (any such Candidate Selection Compound, a “Substitute Compound” solely with respect to such previously
selected Candidate Selection Compound); provided that, for each Candidate Selection Compound that is not deemed a Substitute Compound itself, there may be no more than [***] that [***] a Substitute Compound therefor at any given time. If the JSC
cannot agree whether a particular compound should be designated as a Substitute Compound, neither Party will have final decision-making authority, and such dispute shall be first escalated as described in Section 12.2 and, if necessary, then
decided under the Expert Dispute Resolution Procedures set forth in Section 12.3. For clarity, this Section 2.4.4 is intended to address only the characterization of a Collaboration Compound as a Substitute Compound for purposes of
payments to be made pursuant to Section 6.3.4, and nothing in this Section 2.4.4 shall impact BSP’s or OncoMed’s own decisions on whether or not to Develop and/or Commercialize any Substitute Compound.  

2.5 Development Plans for Candidate Selection Compounds. The Parties have agreed on a Biologic Development Plan proposed by

earlier of ninety (90) days after the Effective Date, enrollment of the first patient in a Clinical Trial relating to a Collaboration Compound that is conducted by or on behalf of BSP, or the filing of the first IND for a Product by BSP, the
Parties will enter into a pharmacovigilance agreement to govern the investigation of and action to be taken with regard to Collaboration Compound-related serious adverse experiences. Such agreement shall contain reasonable terms and conditions as
are typically included in agreements of similar nature, including without limitation provisions enabling each of the Parties to comply with its legal obligations with respect to Collaboration Compound-related serious adverse experiences worldwide.
Such pharmacovigilance agreement will promptly be amended as changes in legal obligations require or as otherwise agreed by the Parties. 
 3. BSP OPTION; SMALL MOLECULE ADVANCEMENT; DEVELOPMENT AND COMMERCIALIZATION OF
BSP DEVELOPMENT COMPOUNDS 
 3.1 BSP Option. 

3.1.1 

3.1.1 BSP Option Exercise. Subject to the terms and conditions of this Agreement, OncoMed hereby grants to BSP the exclusive
right to elect, at its sole discretion, to obtain an exclusive, worldwide license under Section 5.1.1 to Develop and Commercialize Biologic Collaboration Compounds within a given Biologic Collaboration Compound Class as Products under the terms
and conditions set forth in this Agreement (each such right to elect, a “BSP Option”). The BSP Option for each Biologic Collaboration Compound Class shall expire at the end of the BSP Option Period relevant to such Class. BSP shall
exercise the BSP Option by written notice to OncoMed within the applicable BSP Option Period. Upon exercise of a BSP Option, all Biologic Collaboration Compounds in the Class for which the BSP Option has been exercised shall be designated as BSP
Development Compounds, except as otherwise provided in Section 3.1.2, unless and until Section 3.6.7 applies. For clarity, if OncoMed undergoes a Change of Control, BSP shall nonetheless be entitled to exercise the BSP Option as provided
in this Section 3.1. 
 3.1.2 Consequences of Exercise of BSP Option with Respect to Certain Payment Obligations or
Other Classes. In general, BSP may exercise the BSP Option on a Class-by-Class basis prior to expiration of the relevant BSP Option Period. However, the [***], as set forth in this Section 3.1.2 below. 

(a) BSP may exercise the BSP Option for the [***] Class in its entirety [***]. In such case, BSP shall [***], and BSP shall pay
the [***] payment set forth in

the column in Exhibit 6.3.2 [***] but BSP shall not be required to pay the [***] However, in such case, [***]. 
 (b) BSP may exercise the BSP Option for the [***] Class [***], in which case it shall pay the [***] payment set forth in the [***] 

(c) BSP may exercise the BSP Option for the [***] Class in its entirety [***]. In such case, BSP shall pay the [***] payment due
to OncoMed set forth in the [***] upon exercise of the BSP Option for the [***] Class [***]. 
 (d) BSP may exercise the
BSP Option for the [***] Class in either of the situations described in subsections (a) or (c), but choose to [***]. In such case, subsections (a) or (c) shall apply, as applicable, but (i) [***], (ii) BSP shall become
obligated to pay to OncoMed [***], upon such exercise of the BSP Option, and (iii) for clarity, if such exercise is in the situation described in subsection (c), BSP shall pay [***]. 

(e) BSP may exercise the BSP Option with respect to the [***] Class, in which case it shall pay to OncoMed [***]. 

3.1.3 Additional Studies. At least [***] prior to the end of the BSP Option Period for a Biologic Collaboration Compound Class,
BSP shall notify the JSC as to its determination as to whether the data resulting from the Phase Ib Trial for the first Collaboration Compound in such Class is reasonably sufficient for BSP to determine whether to exercise the BSP Option for such
Class, or whether additional preclinical studies or Phase I Trials should be performed to provide data reasonably sufficient for BSP to determine whether to exercise its BSP Option for such Class. If the JSC determines that additional preclinical
studies or Phase I Trials should be performed, OncoMed (reasonably considering any guidance and comments from BSP with respect to such additional preclinical studies or Phase I Trials), or at OncoMed’s discretion BSP, shall conduct such
additional preclinical studies or Phase I Trials, at BSP’s expense, pursuant to an updated Biologic Development Plan for such activities, which shall include a timeline for completion of such activities. If the JSC determines to conduct such
additional preclinical studies or Phase I Trials, the BSP Option Period for such Class will be extended until the date that is [***] after such additional preclinical activities have been completed or such additional Phase I Trials have been
Completed, whichever is later. If the JSC cannot agree whether additional preclinical studies or Phase I Trials should be conducted, [***]. Notwithstanding anything to the contrary, BSP can request such additional studies to be conducted under this
Section 3.1.3 [***]. 
 3.1.4 HSR. 
 (a) If the exercise of any BSP Option requires clearance under the Hart-Scott Rodino Act of 1976, as amended (the “HSR Act”), as determined by BSP, the Parties shall cooperate with
each other in the preparation, execution and filing of all documents that are required (as reasonably determined by BSP) to be filed pursuant to the HSR Act and will use reasonable good faith efforts with all deliberate speed to comply with any
information requests from the Federal Trade Commission (“FTC”) or Department of Justice in connection

with such filing, including without limitation a Request for Additional Information under 15 U.S.C. § 18a and 16 C.F.R. § 803.20 (a “Second Request”), if
applicable. 
 (b) Without limiting the foregoing, the Parties shall promptly make such filings after BSP’s notice
to OncoMed of BSP’s intention to exercise such BSP Option, pending HSR Act clearance. For purposes of clarification, in the event that clearance under the HSR Act is required with respect to any BSP Option, as described above, exercise of such
BSP Option shall not be effective, and no payment under Section 6.3.2 shall be due as a consequence of exercise of such BSP Option, until after the expiration or termination of all applicable waiting periods under the HSR Act; provided that, as
long as BSP has provided notice of its intention to exercise such BSP Option prior to the expiration of the applicable BSP Option Period, then the BSP Option Period will be deemed to extend until the expiration or termination of such waiting periods
(subject to Section 3.1.4(c)). Filing fees under the HSR Act shall be paid by BSP. 
 (c) If a Second Request
issues in connection with any filings required under the HSR Act as described in this Section 3.1.4 and notwithstanding the good faith efforts of the Parties under Section 3.1.4(a), clearance of the relevant exclusive license has not been
obtained from the FTC within [***] after the Parties’ initial premerger notification under the HSR Act in connection with the exercise of a BSP Option, then all Biologic Collaboration Compounds within the relevant Class shall become OncoMed
Development Compounds; provided, however, that if OncoMed has not certified its compliance with all FTC requests made of OncoMed in any Second Request within [***] after the Parties’ initial premerger notification under the HSR Act, such [***]
time period shall be extended by a number of days equal the number of days between the date that is [***] after such notification and the date upon which OncoMed certifies such compliance. 

(d) If BSP exercises the BSP Option but then fails to obtain clearance from the FTC with respect thereto prior to expiration of
the foregoing [***] time period (subject to extension as provided in Section 3.1.4(c)), and OncoMed subsequently itself or through a licensee Develops and Commercializes OncoMed Development Compounds within such Class, then [***], provided that
(i) such failure to clear HSR review was not attributed in material part by the FTC to BSP’s interest in any compound or product that was licensed or acquired by BSP after the Effective Date from a Third Party that modulates a target in
the Pathway and (ii) BSP did not divest its interest in such other compound or product, or take other actions, required by the FTC to obtain such clearance. Such reimbursement shall be paid in the form of an annual royalty of [***] of Net Sales
of OncoMed Development Compound, provided that such payments due to BSP pursuant to this Section 3.1.4(d) shall not [***]. Any disputes relating to [***] under this Section 3.1.4(d) shall be settled using the Expert Dispute Resolution
Procedure of Sections 12.2 and 12.3 to the extent such dispute relates to calculation of the relevant amounts, or, for any other such dispute, shall be settled using the Dispute Resolution Procedure of Sections 12.2 and 12.4. 

3.2 Small Molecule Advancement. Subject to the terms and conditions of this Agreement, OncoMed hereby grants to BSP the exclusive
right, at any time during the time period set forth in Section 6.3.3, to elect to advance Small Molecule Collaboration Compounds

into the Collaboration for further Development and potential Commercialization and to obtain the license under Section 5.1.1 with respect thereto. To exercise such right, BSP shall notify
OncoMed in writing. Upon OncoMed’s receipt of such notice and payment in accordance with Section 6.3.3, all Small Molecule Collaboration Compounds shall be designated as BSP Development Compounds. If BSP does not exercise such right as
provided herein, [***]. For clarity, if OncoMed undergoes a Change of Control, BSP shall nonetheless be entitled to advance Small Molecules into the Collaboration as provided in this Section 3.2. 

3.3 Additional Development. If, due to unexpected [***] factors, OncoMed determines that it is advisable to perform Early
Development work not anticipated in the then-current Biologic Development Plan that is necessary for OncoMed to progress [***] Collaboration Compounds to [***] (“Additional Development”), the costs of which, together with the costs of
previous Development activities OncoMed performed under this Agreement to meet its obligations under Section 2.2.1 prior to its first knowledge of such unexpected factors, are anticipated to exceed the amounts received from BSP under this
Agreement prior to such date by [***] or more (the foregoing, and “Unexpected Cost Increase”), the Parties shall meet to discuss the circumstances giving rise to the Unexpected Cost Increase and to evaluate possible ways of avoiding such
Unexpected Cost Increases, or updating the Development Plan and of [***]. If any such Unexpected Cost Increase is anticipated or occurs, [***].

 6.10 Taxes. In the event that BSP determines that it is required to withhold any tax
to the tax or revenue authorities in any country regarding any payment to OncoMed due to the Law of such country, BSP shall be entitled to deduct and withhold from the amount payable the tax for which BSP is liable under the applicable Law unless
and until an exemption or reduction is granted by the applicable tax or revenue authority. Each of BSP and OncoMed agrees to cooperate in claiming exemptions from such deductions or withholdings under any agreement or treaty from time to time in
effect. If neither Party is permitted to claim an exemption from such deductions or withholdings, BSP may deduct the amount of tax required to be paid (which may include a reduced amount if a reduction is granted by the applicable tax or revenue
authority) from the payment to be made by BSP to OncoMed after notice to OncoMed of such withholding. Within a reasonable amount of time after making such deduction, BSP shall furnish OncoMed with copies of any tax filing or other documentation
evidencing such withholding. Any tax withheld shall be treated as having been paid by BSP to OncoMed all purposes of this Agreement. If it is determined by the applicable tax or revenue authority that BSP failed to make a withholding tax
payment, OncoMed will promptly pay to BSP the amount due to enable BSP to make the missed payment. If it is determined that BSP overpaid withholding tax and OncoMed’s assistance is required to apply for a refund to the applicable tax or
revenue authority, OncoMed shall promptly furnish such information or assistance as may be required.

OncoMed shall provide to BSP copies of any papers relating to the infringement and/or validity litigation of any such involved OncoMed Patents promptly upon their being filed or received.

 (b) If OncoMed elects not to settle, or bring any action or proceeding as described in this Section 8.4.2 within
the earlier of (a) [***] after first notifying BSP or being notified by BSP with respect thereto, or (b) to the extent applicable, the applicable period for listing patents under Section 7002(a) of the Biologics Price Competition and
Innovation Act of 2009, then, upon and after the exercise by BSP of a BSP Option during the Term, BSP may bring such action or proceeding at its own expense, in its own name and entirely under its own direction and control, subject to the following.
OncoMed will reasonably assist BSP (at BSP’s expense) in any such action or proceeding if so requested, and will lend its name to such actions or proceedings if requested by BSP or required by Law. OncoMed shall have the right to participate
and be represented in any such suit by its own counsel at its own expense with respect to a Competitive Infringement relating to a BSP Development Compound. No settlement of any such action or proceeding which restricts the scope, or adversely
affects the enforceability, of any such OncoMed Patent shall be entered into by BSP without the prior written consent of OncoMed, which consent shall not be unreasonably withheld, delayed or conditioned. BSP shall not knowingly take any action
during such litigation of any such OncoMed Patent that would materially adversely affect them, without consultation with OncoMed. 
 (c) Notwithstanding Sections 8.4.2(a) and (b), BSP acknowledges that Article 11 of the Michigan License governs enforcement of the Michigan Patents. Accordingly, BSP agrees that the provisions of
Sections 11.1 through 11.3 of the Michigan License shall be given effect before the provisions of this Section 8.4.2 apply as to actions involving the Michigan Patents. Furthermore, BSP acknowledges that OncoMed does not have the right to
enforce the Patents licensed to OncoMed pursuant to the MorphoSys Agreement. 
 8.4.3 Enforcement of BSP Patents. BSP
will have the sole right, but not an obligation, to bring any action or proceeding involving Competitive Infringement, at its own expense, to enforce or defend, as applicable, any BSP Patent in its own name and entirely under its own direction and
control, subject to the following. OncoMed shall reasonably assist BSP (at BSP’s expense) in any such action or proceeding if so requested, and shall lend its name to such actions or proceedings if required by Law. BSP shall have the final
decision making authority with regard to any action involving the enforcement of a BSP Patent. BSP shall provide to OncoMed copies of any papers relating to the infringement and/or validity litigation of any such involved Relevant BSP Patents
promptly upon their being filed or received. 
 8.4.4 ODC Competitive Infringement. OncoMed will have the sole right,
but not an obligation, to bring any action or proceeding involving ODC Competitive Infringement, at its own expense, to enforce or defend, as applicable, any OncoMed Patent in its own name and entirely under its own direction and control. BSP shall
have the right to participate in such action if a challenge is made to the validity or enforceability of any OncoMed Patent that claims a Product that includes a Late BSP Development Compound. In any such

action in which BSP participates, the Parties will reasonably cooperate to conduct such action in view of each Party’s respective interest in such action. 

8.4.5 Damages. In the event that either Party exercises the rights conferred in this Section 8.4 and recovers any damages or
other sums in such action, suit or proceeding or in settlement thereof, such damages or other sums recovered shall first be subject to Section 8.4.2(c) if such damages relate to the Michigan Patents, and then shall be applied to all
out-of-pocket costs and expenses incurred by the Parties directly in connection with such litigation, including without limitation attorneys’ fees. If such recovery is insufficient to cover all such costs and expenses of both Parties, it shall
be [***]. If after such reimbursement any funds remain from such damages or other sums recovered, [***] (i) [***], and (ii) [***]. 
 8.4.6 Upstream Limitations. Each Party’s rights to enforce an OncoMed Patent pursuant to this Section 8.4, or to defend against a challenge in any action or proceeding described in
Section 8.4.1, shall be subject to the applicable provisions of any agreements between the OncoMed and its licensor. In the event of any conflict between this Section 8.4 and such other agreements, the provisions of the other agreements
shall control. 
 8.5 Patent Term Extension. OncoMed and BSP shall each cooperate with one another and shall use
Commercially Reasonable Efforts in obtaining patent term extension (including without limitation any pediatric exclusivity extensions as may be available) or supplementary protection certificates or their equivalents in any country with respect to
Patents claiming the Products, as applicable. If elections with respect to obtaining such patent term extensions are to be made, BSP shall have the right to elect to seek patent term extension or supplementary protection, provided that such election
will be made so as to maximize the period of marketing exclusivity for the Product. For such purpose, for all Regulatory Approvals, BSP shall provide OncoMed with written notice of any expected Regulatory Approval at least thirty (30) days
prior to the expected date of Regulatory Approval, as well as notice within three (3) Business Days of receiving each Regulatory Approval confirming the date of such Regulatory Approval. 

8.6 Notification of Patent Certification. Each Party shall notify and provide the other Party with copies of any
allegations of alleged patent invalidity, unenforceability or non-infringement of an OncoMed Patent or Relevant BSP Patent pursuant to a Paragraph IV Patent Certification by a Third Party filing an Abbreviated New Drug Application, an application
under Section 505(b)(2), a notification or claim analysis relating to patents under the Biologics Price Competition and Innovation Act of 2009, or other similar patent certification by a Third Party, and any foreign equivalent thereof. Such
notification and copies shall be provided to the other Party within ten (10) days after receipt of such certification. In addition, upon request by OncoMed, BSP shall provide reasonable assistance and cooperation (including without limitation
making available to OncoMed documents possessed by BSP that are reasonably required by OncoMed and making available personnel for interviews and testimony) in any actions reasonably undertaken by OncoMed in accordance with Section 8.4 to
contest any such patent certification or notification.

 8.7 Regulatory Data Protection. To the extent required by or permitted by Law,
BSP will, [***] decide whether to list with the applicable Regulatory Authorities during the Term any applicable Patents for any Collaboration Compound or Product that BSP intends to, or has begun to Commercialize, and that have become the subject
of a marketing application submitted to FDA. Such listings may include without limitation all so called “Orange Book” listings required under the Hatch-Waxman Act and all so called “Patent Register” listings as required in
Canada, or listing of Patents as provided in the patent dispute resolution procedures of the Biologics Price Competition and Innovation Act of 2009. Prior to such decision on listings, the Parties will meet to evaluate and identify all applicable
Patents to be listed and BSP shall listen to any information or opinions provided by OncoMed as to the listing or non-listing of any applicable Patents. 
 8.8 Defense Against Claims of Infringement of Third Party Patents. If a Third Party asserts that a Patent or other right owned by it is or has been infringed by the manufacture, use, sale, offer
for sale, or import of a Late BSP Development Compound or Product in the Territory, the Party first obtaining knowledge of such a claim shall immediately provide the other Party notice of such claim along with the related facts in reasonable detail.
In such event, unless the Parties otherwise agree, BSP shall have the right, but not the obligation, at its expense, to control such defense with respect to such Late BSP Development Compound or Product. OncoMed shall cooperate with BSP, at
BSP’s reasonable request and expense, and shall have the right to be represented separately by counsel of its own choice. BSP shall also control settlement of such claim; provided, however, that no settlement shall be entered into without the
prior consent of OncoMed if such settlement would adversely affect the rights and benefits of, or impose or adversely affect any obligations on, OncoMed. 
 8.9 Third Party Licenses. 
 8.9.1 If either Party reasonably
determines that any Third Party intellectual property rights may be necessary for the Early Development of a Collaboration Compound, where such Third Party intellectual property rights are necessary for use of any Collaboration Compound, or
otherwise that may be required for the use or exploitation of OncoMed Intellectual Property as contemplated under this Agreement for the discovery, research, manufacture, or use of Collaboration Compounds and Products, then such Party will notify
the JSC. 
 8.9.2 After receiving the notification provided in Section 8.9.1, the JSC, in consultation with the
Patent Representatives, will discuss whether the Parties should obtain one or more licenses from one or more Third Parties for such activities or take other appropriate measures in view of such Third Party rights, such as whether the Parties should
obtain an opinion relating to such Third Party intellectual property rights, or take alternative approaches to avoid using such Third Party intellectual property rights. If the JSC determines that the Parties should obtain one or more licenses from
one or more Third Parties for such activities, the JSC will

determine which Party [***]. The chosen Party shall use Commercially Reasonable Efforts obtain a license to such Third Party intellectual property, with the right to sublicense to the extent
necessary for the other Party to conduct its obligations under this Agreement. The non-chosen Party may elect to participate or be consulted in any negotiations for such license and, if the non-chosen Party will bear any obligation in the resulting
license or share costs under Section 8.9.4 with respect to such license, the non-chosen Party must approve the terms of the license. If such chosen Party elects not to obtain rights to such Third Party intellectual property, or is unsuccessful
in obtaining such rights within [***], then the other Party shall have the right (but not the obligation) to negotiate and obtain rights from such Third Party at its sole discretion and expense (subject to Section 8.9.4). 

8.9.3 If either Party reasonably determines that any Third Party intellectual property rights may be necessary for the Late
Development, manufacture, or Commercialization of a Product and are not otherwise described in Section 8.9.1, then BSP shall have the right, but not the obligation, to obtain a license to such Third Party intellectual property, with the right
to sublicense, in order to permit BSP to conduct its obligations under the Agreement. The terms and conditions involved in obtaining such rights shall be determined at BSP’s sole discretion and expense (subject to Section 8.9.4).

 8.9.4 BSP shall have the right to offset against royalties payable to OncoMed pursuant to Section 6.4 an amount
equal to [***] of the [***] owed by BSP to a Third Party pursuant to any license under such Third Party’s intellectual property rights that is necessary for and directly attributable to the exploitation of, and cover [***] (a “Necessary
License”) (other than payments potentially due pursuant to any of the Existing Agreements, which shall be borne solely by OncoMed); provided that the royalties payable to OncoMed under Section 6.4 may not be reduced by more than [***]
of those otherwise due to OncoMed pursuant to Section 6.4 in any Calendar Quarter as a result of such offset. Any unused offset earned in a Calendar Quarter may be carried forward from such Calendar Quarter to the subsequent Calendar Quarters
and may be used in such subsequent Calendar Quarters, subject to the [***] limitation set forth in the immediately preceding sentence. BSP shall pay OncoMed an amount equal to [***] of the royalties and other license fees and costs owed and payable
by OncoMed to a Third Party (other than pursuant to the Existing Agreements) pursuant to any Necessary License to which OncoMed is a party within [***] days after receiving an invoice therefor; excluding, for clarity, any amounts paid to such Third
Party to the extent directly attributable to the exploitation solely of an OncoMed Development Compound. The Parties shall discuss and determine whether any such Third Party License, other than an Existing Agreement, is a Necessary License.

 8.10 Trademarks and Domain Names. 
 8.10.1 BSP shall be responsible for the selection, registration and maintenance of all Trade Marks which it employs in connection with the commercialization of any Product under this Agreement. BSP
shall own and control such Trade Mark and pay all relevant costs thereto.

or trade dress confusingly similar for the marketing, sale or distribution of any goods or products, notwithstanding whether such goods or products have a different use or are dissimilar to the Products. 

8.10.3 Only BSP will be authorized to initiate at its own discretion legal proceedings against any infringement or threatened
infringement of any Trade Mark. 
 8.10.4 BSP shall be responsible for the registration, hosting, maintenance and
defense of any Domain Name. BSP may at its sole and absolute discretion register in its own name or in name of others, host on its own servers or on Third Party servers, maintain and defend such Domain Names and use them for websites.

10.1 BSP Indemnity. BSP shall indemnify, defend and hold harmless OncoMed and its Affiliates, and their respective
officers, directors, employees, agents, licensors, and their respective successors, heirs and assigns and representatives and the University of Michigan (the “OncoMed Indemnitees”), from and against any and all claims, damages,
losses, suits, proceedings, liabilities, costs (including without limitation reasonable legal expenses, costs of litigation and reasonable attorney’s fees) or judgments, whether for money or equitable relief, of any kind (“Losses and
Claims”), to the extent arising out of or relating to, directly or indirectly: (a) the negligence, recklessness or wrongful intentional acts or omissions of BSP, its Affiliates, and/or its Sublicensees and its or their respective
directors, officers, employees and agents, in connection with BSP’s performance of its obligations or exercise of its rights under this Agreement; (b) any breach by BSP of any representation, warranty, or covenant set forth in Article 7;
(c) [***] including without limitation for each of clauses (a), (b) and (c), above, claims and threatened claims based on (i) [***] or (ii) [***] except in any such case for Losses and Claims to the extent [***]. 

10.2 OncoMed Indemnity. OncoMed shall indemnify, defend and hold harmless BSP and its Affiliates, and their respective
officers, directors, employees, agents, licensors, and their respective successors, heirs and assigns and representatives (the “BSP Indemnitees”), from and against any and all Losses and Claims, to the extent arising out of or
relating to, directly or indirectly: (a) the negligence, recklessness or wrongful intentional acts or omissions of OncoMed, its Affiliates, and/or its Sublicensees and its or their respective directors, officers, employees and agents, in

 - 75 -









 
notify the other Party (the “Indemnitor”) in writing promptly upon becoming aware of any claim that may be an Indemnification Claim (it being understood and agreed, however, that
the failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give
notice). The Indemnitor shall have the right to assume and control the defense of the Indemnification Claim at its own expense with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee; provided, however, that an Indemnitee
shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing
interests between such Indemnitee and any other party represented by such counsel in such proceedings. If the Indemnitor does not assume the defense of the Indemnification Claim as described in this Section 10.3, above, the Indemnitee may
defend the Indemnification Claim but shall have no obligation to do so. The Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, and the Indemnitor shall not settle or compromise
the Indemnification Claim in any manner which would have an adverse effect on the Indemnitee’s interests (including without limitation any rights under this Agreement or the scope or enforceability of the OncoMed Intellectual Property, or
Confidential Information or Patent or other rights licensed to OncoMed by BSP hereunder), without the prior written consent of the Indemnitee, which consent, in each case, shall not be unreasonably withheld or delayed. The Indemnitee shall
reasonably cooperate with the Indemnitor at the Indemnitor’s expense and shall make available to the Indemnitor all pertinent information under the control of the Indemnitee, which information shall be subject to Article 9. 

10.4 Insurance. 
 10.4.1 By BSP. BSP hereby represents and warrants to OncoMed that it is self-insured against liability and other risks associated with its activities and obligations under this Agreement for the
activities to be conducted by it under this Agreement, and that such self-insurance is sufficient to meet the obligations set forth in Section 8.3 of the Michigan License.  

10.4.2 By OncoMed. OncoMed shall, beginning with the initiation of the first Clinical Trial for a Collaboration Compound,
maintain at all times thereafter during the Term, and for [***] after termination or expiration of this Agreement, commercial general liability insurance from a recognized, creditworthy insurance company, on an “occurrence basis” which
includes contractual liability coverage and product liability, on a “claims-made basis” with coverage limits of at least [***] per claim and annual aggregate, and is increased to at least [***] before the earlier of the date that OncoMed
initiates the First Commercial Sale of any Product containing an OncoMed Development Compound or BSP initiates the First Commercial Sale of any Product containing a BSP Development Compound. Within [***] following written request from BSP, OncoMed
shall furnish to BSP a certificate of insurance evidencing such coverage as of the date. In the case of a modification or cancellation of such coverage, OncoMed shall promptly provide BSP with a new certificate of insurance evidencing that
OncoMed’s coverage meets the requirements of this Section 10.4.2.

13.3 Force Majeure. Neither Party shall be liable for delay or failure in the performance of any of its obligations
hereunder if such delay or failure is due to causes beyond its reasonable control, including without limitation acts of God, fires, earthquakes, acts of war, terrorism, or civil unrest (“Force Majeure”); provided, however, that the
affected Party promptly notifies the other Party and further provided that the affected Party shall use its Commercially Reasonable Efforts to avoid or remove such causes of non-performance and to mitigate the effect of such occurrence, and shall
continue performance with the utmost dispatch whenever such causes are removed. When such circumstances arise, the Parties shall negotiate in good faith any modifications of the terms of this Agreement that may be necessary or appropriate in order
to arrive at an equitable solution. 
 13.4 Assignment. 

13.4.1 Each Party may, without the consent of the other Party, assign or transfer all of its rights and obligations hereunder to
an Affiliate of or to a successor in interest by reason of merger or consolidation or sale of all or substantially all of the assets of such Party relating to the subject matter of this Agreement; provided however, that (a) such assignment
includes, without limitation, all rights and obligations under this Agreement, (b) such successor in interest or Affiliate shall have agreed as of such assignment or transfer to be bound by the terms of this Agreement in a writing provided to
the non-assigning Party, and (c) where this Agreement is assigned or transferred to an Affiliate, the assigning Party remains responsible for the performance of this Agreement. 

13.4.2 Subject to Section 13.4.1, this Agreement shall inure to the benefit of and be binding on the Parties’
successors and assigns. Any assignment or transfer in violation of the foregoing shall be null and void and wholly invalid, the assignee or transferee in any such assignment or transfer shall acquire no rights whatsoever, and the non-assigning
non-transferring Party shall not recognize, nor shall it be required to recognize, such assignment or transfer. In the event that BSP assigns or otherwise transfers this Agreement to an Affiliate of BSP, BSP hereby agrees to be jointly and severally
liable with any such Affiliates for the actions of such Affiliates and for any and all amounts that become due and payable hereunder to OncoMed. 
 13.4.3 Notwithstanding anything to the contrary in this Agreement, in the event of any such assignment, the intellectual property rights of the acquiring party (if other than one of the Parties to
this Agreement) shall not be included in the technology licensed to the other Party hereunder to the extent held by such acquirer prior to such transaction, or to the extent such technology is developed outside the scope of activities conducted with
respect to Collaboration Compounds, Collaboration Targets or Products. The OncoMed Intellectual Property and the BSP Intellectual Property shall exclude any intellectual property owned or Controlled by a permitted


  
 - 87 -









 
assignee or successor and not developed in connection with Collaboration Compounds, Collaboration Targets or Products. 
 13.4.4 Notwithstanding anything to the contrary in this Agreement, OncoMed shall have the right to assign solely its rights to receive payments pursuant to Article 6, in whole or in part, to a
Third Party purchasing only such interest in such revenues in connection with the monetization of OncoMed’s revenue stream under Article 6, but not the performance of any obligation required under this Agreement without BSP’s written
consent in connection with such assignment; provided that, OncoMed may not assign such interest to any entity that has in active clinical development, under application for Regulatory Approval or in commercialization any compound [***] without the
consent of BSP, which may be withheld in BSP’s discretion. For clarity, this Section 13.4.4 shall not limit OncoMed’s right to assign its rights and obligations under this Agreement as provided in Sections 13.4.1 and 13.4.2.

 13.4.5 If BSP assigns this Agreement to an Affiliate, and such assignment has an adverse tax consequence to OncoMed,
then BSP shall make additional payments to OncoMed under this Agreement to provide OncoMed the payments that would have been due to OncoMed had such assignment not occurred. 
 13.5 BSP Election. BSP represents and warrants that as of the Effective Date it is not conducting Research, Development or Commercialization of any product that is primarily active against a
target in the Pathway (each, a “Section 13.5 Product”). If after the Effective Date either (a) BSP acquires, develops or otherwise comes into Control of any rights to any Section 13.5 Product other than by reason of
activities under this Agreement, or (b) BSP undergoes a Change of Control in which BSP, BSP’s successor or BSP’s Affiliate after such Change of Control occurs Controls rights to, or is otherwise Researching, Developing or
Commercializing, any Section 13.5 Product outside the scope of this Agreement, BSP shall promptly notify OncoMed of such fact in writing. BSP (or its successor) shall, within [***] after providing such notice, either (i) [***] BSP’s,
its successor’s or its Affiliate’s rights with respect to such Section 13.5 Product within [***], (ii) [***] or [***]. 
 13.6 Further Assurances. Each Party agrees to do and perform all such further acts and things and shall execute and deliver such other agreements, certificates, instruments and documents
necessary or that the other Party may deem advisable in order to carry out the intent and accomplish the purposes of this Agreement and to evidence, perfect or otherwise confirm its rights hereunder. Each Party and its Affiliates shall take all
measures reasonably requested by the other Party to give effect to the provisions of this Agreement. Any Affiliate that acquires rights hereunder will be deemed to be bound by the provisions of this 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. 


  
 - 88 -









 13.7 Waivers and Modifications. The failure of any Party to insist on the
performance of any obligation hereunder shall not be deemed to be a waiver of such obligation. Waiver of any breach of any provision hereof shall not be deemed to be a waiver of any other breach of such provision or any other provision on such
occasion or any succeeding occasion. No waiver, modification, release or amendment of any obligation under or provision of this Agreement shall be valid or effective unless in writing and signed by both of the Parties. 

13.8 Governing Law. This Agreement shall be governed by, enforced, and shall be construed in accordance with the Law of the
State of New York, U.S. without regard to any conflicts of law provision that would result in the application of the Law of any State other than the State of New York, U.S. 
 13.9 Relationship of the Parties. Each Party is an independent contractor under this Agreement. Nothing contained herein is intended or is to be construed so as to constitute OncoMed and BSP
as partners, agents or joint venturers. Neither Party shall have any express or implied right or authority to assume or create any obligations on behalf of or in the name of the other Party or to bind the other Party to any contract, agreement or
undertaking with any Third Party. There are no express or implied third party beneficiaries hereunder. 
 13.10 Entire
Agreement. This Agreement and the attached exhibits constitutes the entire agreement between the Parties as to the subject matter of this Agreement, and supersedes and merges all prior and contemporaneous negotiations, representations,
agreements and understandings regarding the same. 
 13.11 Exports. Each Party agrees not to export or re-export,
directly or indirectly, any information, technical data, the direct product of such data, samples or equipment received or generated under this Agreement in violation of any applicable export control Law. 

13.12 Interpretation. 
 13.12.1 Each of the Parties acknowledges and agrees that this Agreement has been diligently reviewed by and negotiated by and between them, that in such negotiations each of them has been
represented by competent counsel and that the final agreement contained herein, including the language whereby it has been expressed, represents the joint efforts of the Parties hereto 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, 

  
 - 89 -









 
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. 

13.12.2 Unless the context requires otherwise, (a) any definition of or reference to any agreement, instrument or other
document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth
herein or therein), (b) any reference to any Law herein shall be construed as referring to such Law as from time to time enacted, repealed or amended, (c) any reference herein to any Person shall be construed to include the Person’s
successors and assigns, and (d) all references herein to Articles, Sections or Exhibits, unless otherwise specifically provided, shall be construed to refer to Articles, Sections and Exhibits of this Agreement. 

13.12.3 Headings and captions are for convenience only and are not be used in the interpretation of this Agreement. 

13.13 Performance by Affiliates. Each Party recognizes that the other Party may perform some or all of its obligations
under this Agreement through Affiliates to the extent permitted under this Agreement, provided, however, that such other Party shall remain responsible for the performance by its Affiliates as if such obligations were performed by such other Party.

 13.14 Compliance with Law. For the avoidance of doubt, the Parties agree that nothing in this Agreement shall
require either Party to commit any act that is in breach of applicable Law. 
 13.15 Counterparts; Electronic
Delivery. This Agreement may be executed in counter-parts with the same effect as if both Parties had signed the same document. All such counterparts shall be deemed an original, shall be construed together and shall constitute one and
the same instrument. Signatures to this Agreement transmitted by facsimile, by email in “portable document format” (“.pdf”), or by any other electronic means intended to preserve the original graphic and pictorial appearance of
this Agreement shall have the same effect as physical delivery of the paper document bearing original signature.

 Press Releases 
 OncoMed Pharmaceuticals and Bayer Schering Pharma
Announce Strategic Alliance to Develop Anti-Cancer Stem Cell Therapeutics 
 Companies Collaborate to Discover and Develop
Multiple Antibody, Protein and Small Molecule Agents Targeting the Wnt Pathway 
 [Redwood City/Berlin] – June 16, 2010 –
OncoMed Pharmaceuticals, Inc. and Bayer Schering Pharma AG, Germany,today announced a global strategic alliance to discover, develop and commercialize novel anti-cancer stem cell therapeutics targeting the Wnt signaling pathway. Cancer stem cells
are a subset of tumor cells believed to play a significant role in the establishment, metastasis and recurrence of cancer. 
 The strategic
alliance leverages OncoMed’s leadership in cancer stem cell drug discovery and development. Under the terms of the agreement, Bayer and OncoMed will develop antibodies, protein therapeutics, and small molecules as potential novel anti-cancer
stem cell therapeutics targeting the Wnt signaling pathway. In addition to an upfront cash payment of $40 million, OncoMed is eligible to receive cash payments for product candidates that Bayer Schering Pharma options and possible additional
payments upon achievement of certain development and commercialization milestones described below. The collaboration could potentially include up to 5 compounds. The agreement includes potential significant near-term milestone payments from Bayer.

 OncoMed will utilize its proprietary human cancer stem cell models to discover and advance antibody and protein therapeutics through Phase 1
clinical studies. Bayer Schering Pharma receives an option to exclusively license antibody and protein therapeutic product candidates at any point up to the completion of Phase 1 testing. Following option exercise, Bayer will lead development and
commercialization of licensed product candidates. For each biotherapeutic drug candidate successfully developed through phase III clinical trials and regulatory approval, OncoMed’s payments could total up to $387.5 million per program,
including potential net sales milestones upon successful commercialization of biotherapeutic products. In addition, OncoMed will be eligible to receive double-digit royalties on net product sales. The agreement contains provisions under which
OncoMed may co-develop antibody and protein therapeutics with Bayer. The collaboration includes OncoMed’s lead Wnt pathway antibody, OMP-18R5, which is currently planned to enter clinical testing in 2011. 

In addition, Bayer will lead the discovery and advancement of small molecule therapeutic candidates that modulate Wnt pathway signaling. OncoMed will
assist Bayer in the evaluation and advancement of small molecule candidates, and is eligible to receive milestone payments of up to $112 million per candidate upon successful development and regulatory approval, including potential net sales
milestones upon successful commercialization of small molecule products. In addition, OncoMed will be eligible to receive single-digit royalties on net product sales. 







 “At Bayer, we recognize the high unmet medical need for cancer treatments. This collaboration with
OncoMed demonstrates our commitment to the development of new and innovative treatment options,” said Prof. Andreas Busch, Head of Global Drug Discovery and Member of the Board of Management at Bayer Schering Pharma. “The development of
anti-cancer stem cell therapeutics together with OncoMed is a highly innovative approach with the potential to perfectly complement our oncology portfolio. Anti-cancer stem cell research could turn out as one of the missing pieces in today’s
cancer therapy .” 
 “Our alliance with Bayer represents a major opportunity to discover and develop an entirely new class of
anti-cancer stem cell therapeutics with one of the leading pharmaceutical companies in the world. Bayer shares our vision for the potential of anti-cancer stem cell therapeutics, and we look forward to working closely with them,” said Paul J.
Hastings, President and CEO of OncoMed. “OncoMed has established a rich pipeline of product candidates targeting a number of critical cancer stem cell pathways. Through this collaboration, we will gain significant additional funding to support
the discovery and development of therapeutics targeting the Wnt pathway, as we continue, with our already strong cash position, and our other sources of collaborative revenue to fully finance and advance all of our programs for years to come.

 About Cancer Stem Cells and the Wnt Signaling Pathway 
 Cancer stem cells, a small, resilient subset of cells found in tumors, have the capacity to self-renew and differentiate, leading to tumor initiation and driving tumor growth, recurrence and metastasis.
Also referred to as “tumor-initiating cells”, these cells were first discovered by OncoMed’s scientific founders in breast cancer and have subsequently been identified in many other types of solid tumor cancers, including cancer of
head and neck, lung, prostate, pancreas, and glioblastoma. Cancer stem cells appear to be preferentially resistant to both standard chemotherapy and radiotherapy. OncoMed’s strategy is to improve cancer treatment by specifically targeting the
key biologic pathways which are thought to be critical to the activity and survival of cancer stem cells. OncoMed’s antibody therapeutics target cancer stem cell proteins and have the potential to be developed against a range of solid tumor
types. 
 The Wnt signaling pathway is one of several identified by OncoMed as an important therapeutic target in halting cancer stem cell
activity. In preclinical studies of monoclonal antibody drug candidates that target Wnt signaling, OncoMed scientists have observed broad-spectrum anti-tumor and anti-cancer stem cell activity in a number of solid tumor types.
