 ARTICLE 2 
 PRODUCT DEVELOPMENT 
 2.1. Development by Millennium. Commencing on
the Effective Date, Millennium shall be responsible for undertaking a development program aimed at ultimately seeking Regulatory Approval for Licensed Products. 
 2.2. Co-Funding Option. Sunesis shall have the right, on a Licensed Product-by-Licensed Product basis, to elect to fund a portion of post Phase I Development Costs of a Licensed Product in all
countries worldwide other than Japan (the “Initial Territory”); provided, however, that Sunesis shall not have the Co-Funding Option with respect to any Licensed Product directed against a Designated Target for which Sunesis has entered
into a Phase II Drug Collaboration. In the event that Sunesis elects to exercise its Co-Funding Option with respect to the Initial Territory for a particular Licensed Product pursuant to the preceding sentence, then Sunesis shall have the right to
elect to fund a portion of post Phase I Development Costs of such Licensed Product in Japan, all in accordance with this Section 2.2. 
 2.2.1 Election. For so long as Sunesis continues to have a Co-Funding Option for a Licensed Product, Millennium shall notify Sunesis [ * ] for each Licensed Product in each of the applicable
territories described above in Section 2.2 where the primary endpoint of such trial involves a preliminary determination of efficacy. Such notice shall include the date [ * ] Sunesis may elect, by so notifying Millennium in writing [
* ] (the “Notice Period”), to participate in funding the further development of such Licensed Product in the applicable territory, as described in this Section 2.2 (such notice, the “Election Notice”). [ * ] until
the end of the Notice Period, Millennium shall cooperate fully with Sunesis, and shall promptly provide Sunesis with access to such material information, to the extent such information is not included in the Initial Development Plan or otherwise has
not been communicated previously to Sunesis, as Sunesis may reasonably request to enable Sunesis to make an informed decision whether to exercise its Co-Funding Option under this Section 2.2 with respect to such Licensed Product. Such
cooperation shall include consulting with Sunesis in good faith regarding the Initial Development Plan, and the financial, scientific and regulatory assumptions reflected therein. In the event Sunesis exercises its Co-Funding Option with respect to
a particular Licensed Product (such Licensed Product, a “Co-Funded Product”), the provisions of Sections 2.2.2 through 2.2.4 below shall apply with respect to such Co-Funded Product in the Co-Funded Territory. The “Co-Funded
Territory” shall consist of the Initial Territory for each Co-Funded Product, and in the event Sunesis elects to exercise its Co-Funding Option for Japan with respect to a particular Co-Funded Product, the Co-Funded Territory shall mean all
territories worldwide for such Co-Funded Product. In the event that Sunesis elects not to exercise the Co-Funding Option with respect to a Licensed Product or fails to provide an Election Notice within the applicable Notice Period, Sunesis shall no
longer have the right to exercise the Co-Funding Option, and Millennium shall have no further obligations under this Section 2.2.1, with respect to such Licensed Product. 
 2.2.2 JDC. For each Co-Funded Product, the Parties shall establish and maintain a JDC in accordance with Section 4.3 below, which shall be responsible for establishing

the plan and budget for the development of each Co-Funded Product (each, a “Co-Development Plan and Budget”) and overseeing the implementation of such plan. Such Co-Development Plan and
Budget shall be comprehensive (as of the time of preparation and delivery hereunder) and shall fully describe at least the proposed activities and data related to [ * ], and other activities and timelines directed to obtaining the initial and
subsequent Regulatory Approvals in each applicable country. Unless otherwise specified in a Co-Development Plan and Budget amounts reflected for a full year shall be deemed budgeted in equal amounts for each calendar quarter of such year.

 2.2.3 Co-Funding Obligation. In the event Sunesis exercises its Co-Funding Option with respect to a Licensed Product,
Sunesis shall be obligated to reimburse Millennium for a percentage (the “Co-Funding Percentage”) of post Phase I Development Costs for such Licensed Product, subject to the provisions of this Section 2.2. It is understood and agreed
that the Co-Funding Percentage shall initially be [ * ] percent ([ * ]%) for each Co-Funded Product. In addition the following shall apply: 
 (a) The Co-Development Plan and Budget will be updated on a quarterly basis. Millennium shall provide to Sunesis its then current estimates for each upcoming budget year for each Co-Funded Product by
November 15 of each year. Promptly following April 1 of each calendar year during the development activities for a particular Co-Funded Product or such other date as is mutually agreed by the Parties, the JDC shall update and amend the
Co-Development Plan and Budget for such Co-Funded Product for the period ending March 31 of the subsequent calendar year. Millennium shall provide Sunesis with reasonable opportunity to provide input into each Co-Development Plan and Budget,
and, subject to Article 4, Millennium shall reasonably consider Sunesis’s comments in establishing and updating each Co-Development Plan and Budget. 
 (b) Within thirty (30) days after the end of each calendar quarter, Millennium shall provide to Sunesis a statement reflecting the total post Phase I Development Costs incurred by Millennium in
accordance with the then-current Co-Development Plan and Budget during such calendar quarter with respect to each Co-Funded Product. Within thirty (30) days after Sunesis’s receipt of such statement, Sunesis shall reimburse Millennium for
the applicable Co-Funding Percentage of the post Phase I Development Costs incurred by Millennium during such calendar quarter for such Co-Funded Product. 
 (c) Upon [ * ] days written notice to Millennium, Sunesis may terminate its Co-Funding Option for a particular Co-Funded Product. In such event, Sunesis’s funding obligation under this
Section 2.2.3 above shall apply only with respect to post Phase I Development Costs for activities conducted with respect to such Co-Funded Product prior to the effective date of such termination. Should Sunesis terminate its Co-Funding Option
under this Section 2.2.3(c) with respect to a particular Co-Funded Product, (i) any royalties payable to Sunesis on such Co-Funded Product shall be paid in accordance with Section 6.3.1, subject to Section 6.3.2(b), and
(ii) Sunesis shall relinquish its right to participate in the JDC pursuant to Section 4.3 and any right to its Co-Promotion Option under Section 3.2 for such Co-Funded Product.

 (d) Upon written notice to Millennium at least ninety (90) days prior to the end
of a budget year, Sunesis may elect to [ * ], by so notifying Millennium in writing, referencing this Section 2.2.3(d) and specifying [ * ]. In such event, Sunesis shall receive a [ * ] in accordance with the schedule set
forth in Section 6.3.2(c) below [ * ]. Upon such election, Sunesis’s previous Co-Funding Percentage under this Section 2.2.3 shall apply only with respect to post Phase I Development Costs for activities conducted with respect
to such Co-Funded Product [ * ] with respect to such Co-Funded Product. Sunesis may [ * ] provided that (i) Sunesis shall not be permitted [ * ] its Co-Funding Percentage for such Co-Funded Product, and (ii) Sunesis
may [ * ]. As used herein, “budget year” shall mean April 1 through March 31, provided that Millennium shall have the right to change the budget year to coincide with Millennium’s annual budget cycle, provided that
Millennium provides Sunesis with at least one hundred twenty (120) days notice of such change. 
 (e) Notwithstanding the
foregoing, in the event that Sunesis experiences a Change in Control, then Sunesis’s Co-Promotion rights under Section 3.2, the right to participate in the JDC under Section 4.3, the right to participate in the JCC under
Section 4.4, and any Licensed Product Teams under Section 2.3 shall terminate. In addition: 
 (i) With respect to
any Co-Funded Product for which Sunesis has exercised its Co-Funding Option prior to such Change of Control, Sunesis’s rights and obligations under this Section 2.2.3 shall continue, provided that Millennium shall no longer be obligated to
provide the detailed plans required of a Co-Development Plan and Budget to Sunesis (or its successor entity), but shall provide Sunesis (or its successor entity) with annual budgets of post Phase I Development Costs for such Co-Funded Product.

 (ii) Sunesis’s Co-Funding Option with respect to future Licensed Products shall continue as well (i.e., with respect to
Licensed Products that are not Co-Funded Products as of the date of such Change of Control), provided that Millennium shall no longer be obligated to provide for each Licensed Product the detailed plans and clinical data required of an Initial
Development Plan and Phase II Notice. Millennium shall, however, provide Sunesis (or its successor entity) with annual budgets of post Phase I Development Costs for such Co-Funded Product in accordance with the timetable for a Phase II Notice set
forth in Section 2.2.1, and shall provide reasonable cooperation to Sunesis (or its successor entity) in evaluating such Licensed Product and the post Phase I Development Costs related thereto, including consulting with Sunesis (or its
successor entity) in good faith regarding such annual budgets and the financial, scientific and regulatory assumptions reflected therein. 
 2.2.4 Certain Terms. As used in this Section 2.2, the following terms shall have the meanings set forth below: 
 (a) “Change in Control” shall mean, [ * ] 
 (b) “Millennium
Competitor” shall mean [ * ] 
 (c) “post Phase I Development Costs” shall mean, with respect to a
particular Co-Funded Product, the Development Costs incurred by Millennium or its Affiliates

following Sunesis’s exercise of the Co-Funding Option for such Co-Funded Product in the Co-Funded Territory for such Co-Funded Product. For the avoidance of doubt, (i) post Phase I
Development Costs shall not include any Development Costs incurred by Millennium or its Affiliates for any subsequent Phase I trials, and (ii) Development Costs relating to activities directed at obtaining Regulatory Approval in Japan for a
Co-Funded Product shall not be considered post Phase I Development Costs to the extent such Development Costs are incurred (A) prior to completion of the Phase I trials for such Co-Funded Product in Japan, or (B) if no Phase I trials are
necessary or performed for such Co-Funded Product in Japan, then prior to initiation of any clinical trial other than a Phase I trial. 
 2.3. Licensed Product Team. Upon identification of a Development Candidate for any Licensed Compound other than BIIB024, the Parties shall form a product team with respect to such Licensed Compound
(which team shall report to the JDC if Sunesis exercises its Co-Funding Option with respect to such Licensed Compound), comprised of Millennium and Sunesis personnel, that will share all relevant information and implement the further development and
regulatory affairs with respect to that Co-Funded Product (each a “Licensed Product Team”) in accordance with the Co-Development Plan and Budget. It is understood that both Millennium and Sunesis shall have the opportunity for meaningful
participation in the activities of a Licensed Product Team commensurate with their respective levels of funding participation; it being further understood that Millennium shall control the Development of the Licensed Product. Sunesis shall be
notified at least two weeks in advance of the date of each Licensed Product Team meeting, which meetings shall be held quarterly by in-person meetings or electronic conference, and shall have the opportunity to have its representatives attend such
meeting. Millennium shall provide such Sunesis representatives with all information distributed to Millennium members of the Licensed Product Team, and such other material information as Sunesis may reasonably request from time to time. With respect
to [ * ], within thirty (30) days after the Effective Date, the Parties shall establish a Licensed Product Team for [ * ] as a Licensed Product (i.e., even though the such Licensed Product is not yet a Co-Funded Product). The
Parties shall maintain any such Licensed Product Team under this Section 2.3 until the Co-Funding Option lapses or is declined with respect to such Licensed Product. For clarity, it is understood that the establishment of a Licensed Product
Team hereunder for a Licensed Product directed at the Raf Target or the [ * ] Target shall not obligate Sunesis to subsequently exercise the Co-Funding Option with respect to such Licensed Product. The Licensed Product Team will be composed
of three (3) representatives of Millennium (at Millennium’s discretion) and three (3) representatives of Sunesis, who shall be appointed (and may be replaced at any time) by the respective Party on written notice to the other Party in
accordance with this Agreement. The Parties may invite additional employee observers based on the subject matter of the meeting, who shall be able to participate in such meetings. The Sunesis representatives shall not be entitled to vote on any
Licensed Product Team matters. In any event, the Licensed Product Team shall terminate in the event that Sunesis does not exercise its Co-Funding Option. 
 2.4. Regulatory Matters. Millennium shall file and be the owner of all regulatory filings for Licensed Compounds or Licensed Products (including Co-Funded Products) developed pursuant to this
Agreement, including all NDAs and Regulatory Approvals, unless otherwise agreed by the Parties.

Co-Funded Product-by-Co-Funded Product and country-by-country basis for any Co-Funded Product, by so notifying Millennium in writing within [ * ] for such Co-Funded Product in such country (each such Co-Funded Product for which Sunesis
exercises the Co-Promotion Option being referred to as a “Co-Promoted Licensed Product”). [ * ] Millennium shall provide Sunesis with a good faith estimate of the number of field force personnel to be deployed for such Co-Funded
Product in the applicable territory for [ * ], together with a then-current Sales and Marketing Plan for such Co-Funded Product. The estimate of the number of field force personnel to be deployed shall be prepared by the JCC, and shall take
into consideration the then-current marketing and promotion practices in the relevant markets and the number and nature of other products, if any, including the detail position, if applicable, that such field force personnel will be selling. In
situations where field force personnel will be selling multiple products, the JCC shall make a good faith allocation of the field force personnel’s time to be spent on each product. In the event that Sunesis elects not to exercise the
Co-Promotion Option with respect to a Co-Funded Product or fails to notify Millennium in writing of its election within the applicable [ * ] in any country, Sunesis shall no longer have the right to exercise the Co-Promotion Option with
respect to such Co-Funded Product in such country. 
 As used in this Agreement, “co-promote” or
“co-promotion” shall mean to promote jointly or joint promotion of a Licensed Product through Millennium’s and Sunesis’s respective sales forces under the same brand name, with Millennium booking all sales of such Co-Promoted
Licensed Product, all as shall be more specifically set forth in a co-promotion agreement for each of the countries in which Sunesis co-promotes, such agreement to be negotiated in good faith as soon as practicable following the exercise by Sunesis

Co-Promoted Licensed Product) and benefits, pension, insurance, social security and any other related obligations. 
 3.2.2
Co-Promotion Obligations. Sunesis shall employ a professional and trained sales force to co-promote the Co-Promoted Licensed Product, and such sales force shall meet standards of competence and professionalism as are common in the
pharmaceutical industry. In all events, Sunesis’s co-promotion shall be conducted as directed by the JCC and in accordance with the then current Sales and Marketing Plan and in accordance with all applicable laws. Millennium shall provide to

to the deadline, that Millennium should continue to file or prosecute such Collaboration Patent. Millennium shall then have the option to decide, with at least twenty (20) business days notice to Sunesis to: (i) continue to file or
prosecute such Collaboration Patent at its cost and expense, or (ii) allow Sunesis to file or prosecute such Collaboration Patent at its own cost and expense using counsel of its own choice. In the event that Millennium elects option (ii), then
Millennium shall cooperate with Sunesis to promptly transfer relevant prosecution materials to Sunesis. It is understood and agreed that transfer of prosecution of particular Collaboration Patents pursuant to subsection (ii) above shall not
affect the ownership or licenses otherwise provided in this Agreement. 
 9.3. Enforcement. Subject to the rights of
Biogen Idec under the Millennium-Biogen Agreement: 
 9.3.1 Notice. In the event a Party becomes aware of any actual or
potential infringement or misappropriation of the Sunesis Licensed Technology (a “Subject Infringement”), such Party shall notify the other Party. 
 9.3.2 Millennium. Subject to the terms of this Section 9.3.2, Millennium shall have the sole right, but not the obligation, to take legal action to enforce and defend the Sunesis Licensed
Technology against Subject Infringements by Third Parties at its sole cost and expense, to the extent such Subject Infringement is within the field of use of Millennium’s exclusive license under Section 5.1.1 above. If, within [ * ]
following a request by Sunesis to do so, Millennium fails to take such action to enforce the Sunesis Licensed Patents with respect to a Subject Infringement, Sunesis or its designee shall, in its sole discretion, have the right, at its sole expense,
to take such action. In addition, Millennium shall have the sole right, but not the obligation, to take legal action to enforce and defend any actual or potential infringement or misappropriation of the Biogen Idec Collaboration Technology.

 9.3.3 Sunesis. To the extent a Subject Infringement is not covered by Section 9.3.2 above, Sunesis (or its
designee) shall have the initial right, but not the obligation, to take reasonable legal action to enforce and defend the Sunesis Licensed Technology against such Subject Infringements by Third Parties at its sole cost and expense. If, within [ *
] following a request by Millennium to do so, Sunesis fails to take such action to enforce the Sunesis Licensed Patents with respect to such Subject Infringement, and the Subject Infringement is in a field not then licensed exclusively to
Sunesis hereunder, Millennium or its designee shall, in its sole discretion, have the right, at its sole expense, to take such action. 
 9.3.4 Cooperation; Costs and Recoveries. If a Party (the “Controlling Party”) brings an action with respect to a Subject Infringement in accordance with this Section 9.3 (an
“Infringement Action”), then the other Party (the “Cooperating Party”) shall cooperate as reasonably requested, at such Controlling Party’s expense, in the pursuit of such Infringement Action, including if necessary by
joining as a nominal Party to the Infringement Action. In any case, the Cooperating Party shall have the right, even if not required to be joined, to participate in

such Infringement Action with its own counsel at its own expense. The costs and expenses of the Infringement Action shall be the responsibility of the Controlling Party, and any damages or other
monetary rewards or settlement payments actually received and retained by the Controlling Party shall first be applied to reimburse the Controlling Party’s out-of-pocket expenses directly attributed to the Infringement Action, then the other
Party’s out-of-pocket expenses directly attributed to the Infringement Action, and the remainder shall be shared as follows: [ * ] 
 ARTICLE 10 
 CONFIDENTIALITY 

10.1. Confidentiality. During the Term of this Agreement and for a period of [ * ] years following the expiration or
earlier termination hereof, each Party shall maintain in confidence the Confidential Information of the other Party, shall not use or grant the use of the Confidential Information of the other Party except as expressly permitted hereby, and shall
not disclose the Confidential Information of the other Party (in each case, irrespective of whether such Confidential Information is also the Confidential Information of the receiving Party), except (i) on a need-to-know basis to such
Party’s directors, officers and employees, (ii) to such Party’s consultants performing work contemplated by the Agreement, and to any bona fide subcontractor performing work for such Party hereunder, or (iii) to the extent such
disclosure is reasonably necessary in connection with such Party’s activities under rights and licenses expressly authorized by this Agreement (including the permitted sublicensees). To the extent that disclosure to any person is authorized by
this Agreement, prior to disclosure, a Party shall obtain written agreement of such person to hold in confidence and not disclose, use or grant the use of the Confidential Information of the other Party except as expressly permitted under this
Agreement. Each Party shall notify the other Party promptly upon discovery of any unauthorized use or disclosure of the other Party’s Confidential Information. 
 10.2. Permitted Use and Disclosures. The confidentiality obligations under this Article 10 shall not apply to the extent that a Party is required to disclose information by applicable law,
regulation or order of a governmental agency or a court of competent jurisdiction; provided, however, that such Party shall provide written notice thereof to the other Party (to the extent not prohibited by law or court order), and
consult with the other Party with respect to such disclosure to the extent reasonably protectable and provide the other party reasonable opportunity to object to any such disclosure or to request confidential treatment thereof. Notwithstanding the
provisions of this Section, either Party may, to the extent necessary, disclose Confidential Information of the other Party, to any governmental or regulatory authority in connection with the development of a product which it has the right to
develop under this Agreement. 
 10.3. Nondisclosure of Terms. Each of the Parties hereto agrees not to disclose the
financial terms of this Agreement to any Third Party without the prior written consent of the other Party hereto, which consent shall not be unreasonably withheld, except (a) to such Party’s attorneys, advisors, investors, potential
bona fide collaborators and Sublicensees, and others on a need-to-know basis under circumstances that reasonably protect the confidentiality thereof; (b) or to the extent required by law (and with appropriate requests made for
confidential treatment),

including filings required to made by law with the Securities and Exchange Commission or any national securities exchange; provided, however, that, with respect to any filing required to made by
law with the Securities and Exchange Commission or any national securities exchange, the Party subject to such filing requirement shall, at least ten (10) business days in advance of any such filing, provide the other Party with a draft set of
redactions to this Agreement for which confidential treatment will be sought, reasonably incorporate the other Party’s comments as to additional terms it would like to see redacted, and seek confidential treatment for such additional terms
(except only in the limited circumstances where confidential treatment is in the opinion of outside counsel unavailable); or (c) to Biogen Idec, to the extent required under the Three Party Agreement or Millennium-Biogen Agreement.
Notwithstanding the foregoing, (i) Sunesis may issue the press release to be mutually agreed by the Parties, and (ii) each Party may disclose the information contained in such press release (and related Securities and Exchange Commission
filing) without the consent of the other Party. 
 10.4. Publication. 

10.4.1 By Sunesis. Any manuscript by Sunesis on subject matter in connection with the Research Program relating to the Designated
Targets or Licensed Compounds to be published or publicly disclosed shall be subject to the prior review of Millennium at least [ * ] prior to submission. Further, to avoid loss of patent rights as a result of premature public disclosure of
patentable information, Millennium shall notify Sunesis in writing within [ * ] after receipt of any disclosure whether Millennium desires to file a patent application on any invention disclosed in such scientific results. In the event that
Millennium desires to file such a patent application, Sunesis shall withhold publication or disclosure of such scientific results until the earlier of (i) a patent application is filed thereon, (ii) the Parties determine after consultation
that no patentable invention exists, or (iii) [ * ] after receipt by Sunesis of Millennium’s written notice of Millennium’s desire to file such patent application. Further, if such scientific results contain the information of
Millennium that is subject to use and nondisclosure restrictions under this Article 10, Sunesis agrees to remove such information from the proposed publication or disclosure. For clarity, nothing in this Section 10.4 shall be deemed to
limit the publication or disclosure right of Sunesis with respect to a Reverted Licensed Product. 
 10.4.2 By
Millennium. Millennium shall have the right, but not the obligation, to publish or publicly disclose, in its sole discretion, any manuscript containing scientific or clinical results generated during the Term relating to the Designated Targets,
Licensed Compounds or Licensed Products, and shall provide Sunesis with a courtesy copy of such manuscript prior to its publication. 
 10.4.3 Patent Applications. Following the filing of any patent application within the Collaboration Technology, in the period prior to the publication of such a patent application, neither Party
shall make any written public disclosure regarding any invention claimed in such patent application without the prior consent of the other Party.

 ARTICLE 12 
 INDEMNIFICATION 

12.1. Millennium. Millennium shall indemnify, defend and hold harmless Sunesis and its Affiliates and their respective directors,
officers, employees, agents and their respective successors, heirs and assigns from and against any losses, costs, claims, damages, liabilities or expense (including reasonable attorneys’ and professional fees and other expenses of litigation)
(collectively, “Liabilities”) resulting from any claims, demands, actions or other proceedings by any Third Party to the extent resulting from: (i) the manufacture, use, sale, handling or storage of Licensed Products by Millennium or
its Affiliates or Sublicensees or other designees (except with respect to claims of infringement or violation of intellectual property rights, which shall be governed solely by clause (iv)); (ii) the breach by Millennium of the
representations and warranties made in this Agreement; (iii) [ * ] Millennium or any of its agents or employees or failure of Millennium or any of its agents or employees to comply with applicable laws and regulations; or (iv) a
claim that the use, manufacture, sale or importation of a Licensed Product infringes or violates the intellectual property rights of a Third Party (other than if such infringement or violation results solely from the practice of any Sunesis Licensed
Technology (excluding any Joint Sunesis-Biogen Idec Collaboration Patents and Joint Sunesis-Biogen Idec Collaboration Know-How) and Sunesis Core Technology in accordance with this Agreement); except, in each of cases (i)–(iv), to the extent

Sunesis or its Affiliates or Sublicensees or other designees, (ii) the breach by Sunesis of its representations and warranties made in this Agreement or the Original Agreement, or
(iii) [ * ] Sunesis or any of its agents or employees or failure of Sunesis or any of its agents or employees to comply with applicable laws and regulations; except, in each case, to the extent such Liabilities result from a breach of
this Agreement by Millennium, [ * ] Millennium or any of its agents or employees (including sales representatives involved in co-promoting any Co-Promoted Licensed Product) or failure of Millennium or any of its employees or agents to comply
with applicable laws or regulations. 
 12.3. Procedure. If a Party (the “Indemnitee”) intends to claim
indemnification under this Article 12, it shall promptly notify the other Party (the “Indemnitor”) in writing of any claim, demand, action or other proceeding for which the Indemnitee intends to claim such indemnification, and the
Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel mutually satisfactory to the Parties; provided, however, that an Indemnitee shall have the right to retain
its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between the Indemnitee and
any other Party represented by such counsel in such proceeding. The obligations of this Article 12 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the consent of
the Indemnitor, which consent shall not be withheld or delayed unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve the Indemnitor of any obligation to the Indemnitee under this Article 12. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any claim,
demand, action or other proceeding covered by this Article 12. The Indemnitor shall not, without the Indemnitee’s consent, which consent shall not be withheld or delayed unreasonably, consent to the entry of any judgment or accept any
settlement with respect to such claim, demand, action or proceeding which imposes liability not covered by this indemnification or restrictions on the Indemnitee. 
 ARTICLE 13 
 TERM AND TERMINATION 

13.1. Term. The Term of this Agreement shall commence on the Effective Date, and shall continue in full force and effect on a
country-by-country and Product-by-Product basis until expiration of both Parties’ royalty payment obligations in such country with respect to such Products, in each case unless earlier terminated as provided in this Article 13 (the
“Term”). 
 13.2. Termination for Breach. Either Party to this Agreement may terminate this Agreement in the
event the other Party hereto shall have materially breached or defaulted in the performance of any of its material obligations hereunder, and such default shall have continued for [ * ] after written notice thereof was provided to the
breaching Party by the non-breaching Party. Any termination shall become effective at the end of such [ * ] period unless the breaching Party has cured any such breach or default prior to the expiration of the [ * ] period.

Notwithstanding the foregoing, failure by either Party to use Commercially Reasonable and Diligent Efforts with respect to the development and commercialization of a Product shall not be deemed a
breach of this Agreement. Sunesis hereby waives any breaches or defaults by Biogen Idec under the Original Agreement and acknowledges and agrees that any future breaches or defaults by Biogen Idec under the New Sunesis-Biogen Agreement shall have no
bearing on this Agreement. 
 13.3. Termination For Bankruptcy. Either Party hereto shall have the right to terminate
this Agreement forthwith by written notice to the other Party (i) if the other Party is declared insolvent or bankrupt by a court of competent jurisdiction, (ii) if a voluntary or involuntary petition in bankruptcy is filed in any court of
competent jurisdiction against the other Party and such petition is not dismissed within ninety (90) days after filing, (iii) if the other Party shall make or execute an assignment of substantially all of its assets for the benefit of
creditors, or (iv) substantially all of the assets of such other Party are seized or attached and not released within ninety (90) days thereafter. All rights and licenses granted under this Agreement by one Party to the other Party are,
and shall otherwise be deemed for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 (56) of the Bankruptcy Code. The Parties agree that the
licensing Party under this Agreement shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code in the event of a bankruptcy by the other Party. The Parties further agree that in the event of the commencement of a
bankruptcy proceeding by or against one Party under the Bankruptcy Code, the other Party shall be entitled to complete access to any such intellectual property pertaining to the rights granted in the licenses hereunder of the Party by or against
whom a bankruptcy proceeding has been commenced and all embodiments of such intellectual property. 
 13.4. Termination for
Convenience by Millennium. Provided that Millennium is not in breach of this Agreement, Millennium will have the right to terminate this Agreement at any time, by providing [ * ] prior written notice. 

13.5. Effect of Breach or Termination. 
 13.5.1 Accrued Rights and Obligations. Termination of this Agreement for any reason shall not release either Party hereto from any liability which, at the time of such termination, has already
accrued to the other Party or which is attributable to a period prior to such termination nor preclude either Party from pursuing any rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement.

 13.5.2 Termination by Millennium for Breach or Bankruptcy of Sunesis. In the event of termination of this Agreement by
Millennium pursuant to Section 13.2 due to Sunesis’s breach or by Millennium pursuant to Section 13.3 for Sunesis’s bankruptcy, in addition to those provisions surviving under Section 13.8, the following shall apply:

survive with respect to Co-Funded Products for which Sunesis has exercised its Co-Funding Option prior to such termination, and Millennium shall pay royalties on any such Co-Funded Products in accordance with Section 6.3.2. Millennium shall no
longer be obligated to provide the detailed plans required of a Co-Development Plan and Budget to Sunesis, but shall provide Sunesis with annual budgets of post Phase I Development Costs for any such Co-Funded Products. Sunesis’s Co-Funding
Option with respect to future Licensed Products shall terminate, as will Article 3, as well as Sunesis’s right to participate in the JDC under Section 4.3 and any Licensed Product Teams under Section 2.3. 

13.5.3 Termination by Sunesis for Breach or Bankruptcy of Millennium. In the event of any termination by Sunesis pursuant to

 13.6.3 Millennium’s rights with respect to Co-Funded Products and the Co-Funded Option shall be as follows: 

(a) With respect to any Co-Funded Product for which Sunesis has exercised its Co-Funding Option, and for which Millennium has not
obtained Regulatory Approval in any territory in the Co-Funded Territory for such Co-Funded Product, in each case as of the effective date of such termination, such Co-Funded Product shall become a Reverted Licensed Product in accordance with
Section 8.2 and Exhibit 8.2 and Sunesis shall thereafter pay royalties to Millennium on Net Sales of such Reverted Licensed Product in accordance with Section 6.4. 
 (b) With respect to any Co-Funded Product for which Sunesis has exercised its Co-Funding Option, and for which Millennium has obtained Regulatory Approval in any territory in the Co-Funded Territory for
such Co-Funded Product, in each case as of the effective date of such termination, Sunesis’s rights and obligations under Section 2.2.3 shall survive, and Millennium shall pay royalties on any such Co-Funded Products in accordance with
Section 6.3.2. Millennium shall no longer be obligated to provide the detailed plans required of a Co-Development Plan and Budget to Sunesis, but shall provide Sunesis with annual budgets of post Phase I Development Costs for any such Co-Funded
Products. Sunesis’s Co-Funding Option with respect to future Licensed Products shall terminate, as will Article 3, as well as Sunesis’s right to participate in the JDC under Section 4.3 and any Licensed Product Teams under
Section 2.3. 
 (c) Sunesis’s Co-Funding Option under Section 2.2 with respect to future Licensed Products shall
continue (i.e., with respect to Licensed Products that are not Co-Funded Products as of the effective date of such termination), provided that Millennium shall no longer be obligated to provide for each Licensed Product the detailed plans and
clinical data required of an Initial Development Plan and Phase II Notice pursuant to Section 2.2.1. Millennium shall, however, provide Sunesis with annual budgets of post Phase I Development Costs for such Co-Funded Product in accordance with
the timetable for a Phase II Notice set forth in Section 2.2.1, and shall provide reasonable cooperation to Sunesis in evaluating such Co-Funded Product and the post Phase I Development Costs related thereto, including consulting with Sunesis
in good faith regarding such annual budgets and the financial, scientific and regulatory assumptions reflected therein. 
 13.7.
Transition of Information and Materials. With respect to a Party’s obligation to transition Collaboration Technology, information and material with respect to a particular Licensed Compound, each Party shall cooperate fully (and cause
its Affiliates to cooperate fully) with the other Party to facilitate a smooth and prompt transition of Collaboration Technology,

information and materials that are necessary or useful for the receiving Party to exercise its licensed rights hereunder with respect to such Licensed Compound. 

13.8. Survival Sections. In addition to the provisions set forth in Sections 13.5.2, 13.5.3 and 13.6 above, as applicable, the
following provisions shall survive the expiration or termination of this Agreement for any reason: Articles 1 (Definitions), 7 (Payments, Books and Records), 10 (Confidentiality), 11 (Representations and Warranties), 12 (Indemnification), 13

 ARTICLE 14

 DISPUTE RESOLUTION 
 14.1. Escalation to Senior Executives. In the event of a dispute or matter of significant concern arises between the Parties, then at the request of either Party, the matter shall be escalated to a
senior executive from each Party. Such senior executive shall be either the CEO of such Party, or another senior executive of such Party who both reports to the CEO and who has direct management responsibility for the matter in dispute. Upon such
request, such senior executives shall make themselves reasonably available to meet, and shall meet either by telephone or if, specifically requested, in person, to attempt to resolve such matter, and shall thereafter continue to use good faith
efforts to attempt to resolve such matter unless it becomes clear that the matter cannot be resolved by mutual agreement. Thereafter either Party may pursue such legal process as is otherwise available under applicable law. 

14.2. Injunctive Relief. This Article 14 shall not be construed to prohibit either Party from seeking preliminary or permanent
injunctive relief, restraining order or degree of specific performance in any court of competent jurisdiction to the extent not prohibited by this Agreement. For avoidance of doubt, any such equitable remedies provided under this Article 14 shall be
cumulative and not exclusive and are in addition to any other remedies, which either Party may have under this Agreement or applicable law. 
 14.3. Matters to Proceed to Court. Notwithstanding the foregoing, any dispute relating to the determination of validity of a Party’s patents or other issues relating solely to a Party’s
intellectual property and any dispute asserting breach of this Agreement or of the representations and warranties made hereunder shall be submitted exclusively to the federal court in Delaware, and the Parties hereby consent to the jurisdiction and
venue of such court. 
 ARTICLE 15 
 MISCELLANEOUS 
 15.1. Governing Laws. This Agreement and any dispute
arising from the construction, performance or breach hereof shall be governed by and construed, and enforced in accordance with, the laws of the state of Delaware, without reference to conflicts of laws principles.

 15.3. Assignment. This Agreement shall not be assignable by either Party without the written consent of the other Party hereto, except either Party may assign this Agreement without such consent to
its Affiliates, or to an entity that acquires all or substantially all of the business or assets of such Party whether by merger, reorganization, acquisition, sale, or otherwise; provided, however, that the assignee shall agree in writing to be

 15.8. Severability. In the event that any provision of this Agreement becomes or is declared by a
court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect to the fullest extent permitted by law without said provision, and the Parties shall amend the Agreement to the extent
feasible to lawfully include the substance of the excluded term to as fully as possible realize the intent of the Parties and their commercial bargain. If a Party seeks to avoid a provision of this Agreement by asserting that such provision is
invalid, illegal or otherwise unenforceable, the other Party shall have the right to terminate this Agreement upon sixty (60) days’ prior written notice to the asserting Party, unless such assertion is eliminated and cured within such
sixty (60) day period. If Millennium has sought to so avoid a provision of this Agreement, such termination shall be deemed a termination by Millennium under Section 13.4 above, and if Sunesis has sought such an avoidance, such termination
shall be deemed a termination by Millennium for breach by Sunesis under Section 13.2 above. 
 15.9. Advice of
Counsel. Sunesis and Millennium have each consulted counsel of their choice regarding this Agreement, and each acknowledges and agrees that this Agreement shall not be deemed to have been drafted by one Party or another and will be construed

agreement, both written and oral, between the Parties with respect to the subject matter hereof, and all prior agreements respecting the subject matter hereof, either written or oral, express or implied, shall be abrogated, canceled, and are null
and void and of no effect. No amendment or change hereof or addition hereto shall be effective or binding on either of the Parties hereto unless reduced to writing and executed by the respective duly authorized representatives of Sunesis and
Millennium.
