 AMENDED AND RESTATED 
 RESEARCH AND DEVELOPMENT AGREEMENT 
  
 This AMENDED AND RESTATED RESEARCH AND DEVELOPMENT AGREEMENT (this “Agreement”) is entered into as of June 9, 2005 (the “Effective Date”) by and among EXELIXIS, INC., a
Delaware corporation (“Exelixis”), SYMPHONY EVOLUTION, INC., a Delaware corporation (“Symphony Evolution”) (each of Exelixis and Symphony Evolution being a “Party,” and
collectively, the “Parties”), and SYMPHONY EVOLUTION HOLDINGS LLC, a Delaware limited liability company (“Holdings”) (which shall be a Party to this Agreement solely with respect to Article 1
and Section 7.5). Capitalized terms used herein and not defined herein shall have the meanings assigned to such terms in Annex A attached hereto. 
  

PRELIMINARY STATEMENT 
  
 Exelixis and Holdings have entered into that certain Research and Development Agreement, dated as of June 9, 2005 (the “Research and
Development Agreement”). Pursuant to this Agreement, Holdings desires to assign all of its rights and delegate its obligations under the Research and Development Agreement to Symphony Evolution, and Exelixis and Symphony Evolution
desire to amend and restate the terms and conditions of the Research and Development Agreement. 
  
 In the Novated and Restated Technology License Agreement, Exelixis grants Symphony Evolution an exclusive license to develop and commercialize certain
compounds. Symphony Evolution wishes for Exelixis to continue to develop such compounds. Symphony Evolution and Exelixis desire to establish, and agree on the responsibilities of, a Development Committee to oversee such development. Exelixis and
Symphony Evolution further desire to comply with and perform certain agreements and obligations related thereto. 
  
 The Parties hereto agree as follows: 
  

	1.	Assignment. The Parties agree that from and after the Effective Date, all of the rights and obligations of Holdings under the Research and Development Agreement will
be assigned and transferred to, and assumed by, Symphony Evolution. 

  

	2.	Overview of the Development. The Parties shall develop the Programs in a collaborative and efficient manner. The Parties shall engage in joint decision-making for the
Programs as set forth in Articles 3 and 4. As between the Parties, Exelixis shall be the sole Party performing pre-clinical and clinical development, all scientific and technical services associated with such development, and patent work
under the Programs, including all matters set forth in the Clinical Plan, and Symphony Evolution shall be responsible for all matters set forth in the Management Plan. 

  

	3.	Development Committee. The Parties shall establish and maintain a committee (the “Development Committee”) to oversee the development of the
Programs. The Development Committee shall be established, operated and governed in accordance with 

  

 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 the policies and procedures set forth in Annex B hereto (the “Development Committee
Charter”). The Development Committee Charter may only be amended with the consent of the Development Committee and the approval of Symphony Evolution and Exelixis. In no event shall the Development Committee have the power to amend the
terms of any Operative Documents. 
  

	4.	Development Plan and Development Budget. 

  
 4.1 Generally. The Parties have agreed to a Development Plan and Development Budget as of the Effective Date, which are attached hereto and
incorporated herein as Annex C and Annex D, respectively. Such Development Plan consists of two (2) plans: (a) a plan that governs all clinical, scientific, technical, regulatory and patent work to be performed under the Operative
Documents (the “Clinical Plan”), and (b) a plan that governs all other matters pertaining to Symphony Evolution (the “Management Plan”). The Clinical Plan includes without limitation (i) an outline of
the clinical plan for each Program, (ii) all available Protocols for each Program, (iii) detailed synopses for each Program for which Protocols have not yet been developed, and (iv) outlines of non-clinical activities, key regulatory and quality
activities, and CMC activities for each Program. The Development Budget consists of a budget for the Clinical Plan (the “Clinical Budget”) and a budget for the Management Plan (the “Management
Budget”). The Clinical Budget is further divided into a separate budget for each Protocol, and shall include without limitation budget spreadsheets summarizing anticipated costs of engaging third party service providers for such
Protocol and scope of Protocol-related work to be performed by such third parties. Notwithstanding the foregoing, the number of full-time equivalents (“FTEs”) to be dedicated to the Programs by Exelixis shall be specified in
the Clinical Budget, by function and work responsibilities, on a Program by Program basis. All anticipated or actual expenditures of Symphony Evolution, including without limitation, compensation of members of the Symphony Evolution Board, are
included in the Development Budget attached hereto as Annex D and will be continue to be included in any amendments thereof. 
  
 4.2 Amendments. 
  
 (a) Subject to Sections 5.1 and 8.3, all amendments of and, subject to Sections 5.1, 6.2 and 8.3, all deviations from the Development Plan and
Development Budget shall be made in accordance with the procedures described in this Article 4 or the Management Services Agreement, as applicable, and the Development Committee Charter, including obtaining the approval of the Symphony Evolution
Board. 
  
 (b) The Development Committee shall review the
Development Plan and Development Budget [ * ] to determine whether any changes are needed and shall comply with all procedures required to amend the Development Plan or Development Budget to implement such changes. 
  
 (c) Notwithstanding anything in this Agreement to the contrary, if
Exelixis desires to: (i) add a Protocol for which there is no detailed synopsis in the Clinical Plan; (ii) adopt a Protocol which materially deviates from its corresponding synopsis in the Clinical Plan; (iii) eliminate a Protocol (including for a
Medical Discontinuation Event); (iv) pursue a new

 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 indication for a Program; (v) make any material change to the non-clinical activities or CMC activities described in the
Program outlines; (vi) make any change in a Protocol that, based on Exelixis’ reasonable judgment, would result in a delay of more than [ * ] in the completion of a Protocol; (vii) make any material change in the entry criteria for a
Protocol; (viii) make any change to the primary study endpoint of a Protocol; or (ix) make any change to other endpoints or outcome measures of a Protocol that, based on Exelixis’ reasonable judgment, is likely to materially affect the label,
cost, feasibility or timeline of such Protocol, then it shall propose to the Development Committee that the Clinical Plan and, if applicable, the Clinical Budget be amended to reflect such change; provided, however that with respect to the adoption
of a Protocol that materially deviates from its corresponding detailed synopsis, the Clinical Plan need only be amended to account for such material deviations. Subject to Section 4.3, Exelixis shall not implement any of the changes described
in this Section 4.2(c) until the Clinical Plan and, if applicable, Clinical Budget are so amended. 
  
 (d) The Clinical Budget shall be periodically amended to account for any additional expenditures approved by a Development Committee Member
appointed by Symphony Evolution (“Symphony Member”) in accordance with Section 8.3(b). If the Symphony Member denies an Exelixis additional expenditure request made pursuant to Section 8.3(b), the Development
Committee shall convene an Ad Hoc Meeting as soon as practical thereafter to consider amending the Clinical Budget to include such additional expenditure. 
  
 (e) If Exelixis brings to the Development Committee’s attention a potential additional expenditure pursuant to Section 8.3(c), the
Development Committee shall consider amending the Clinical Budget to include such additional expenditure at the next meeting of the Development Committee. 
  
 (f) A Protocol may only be discontinued or abandoned in the event that either (i) (A) a Medical Discontinuation Event arises in such Protocol or
(B) the Parties mutually agree, based on scientific evidence (regardless of whether such evidence was generated by a Party or a third party), that [ * ] (a “Scientific Discontinuation Event”), or (ii) the Symphony
Board, by unanimous vote, resolves to discontinue or abandon a Protocol. The Development Committee shall promptly thereafter amend the Clinical Plan to reflect such discontinuation or abandonment and amend the Clinical Budget to reallocate to any or
all of the remaining Protocols the funds previously allocated to the discontinued or abandoned Protocol (with any funds not then allocated to another Protocol to be held for reallocation by the Development Committee at another time). 
  
 (g) A Program may only be discontinued or abandoned in the event that
either (i) the Parties mutually agree to discontinue or abandon such Program based on a Medical Discontinuation Event or Scientific Discontinuation Event that arose in a Protocol in such Program, or (ii) the Symphony Board, by unanimous vote,
resolves to discontinue or abandon such Program. The Development Committee shall promptly thereafter amend the Clinical Plan to reflect such discontinuation or abandonment and amend the Clinical Budget to reallocate to any or all of the remaining
Programs the funds previously allocated to the discontinued or abandoned Program (with any funds not then allocated to be held for reallocation by the Development Committee at another time).

 (h) The Parties acknowledge that Exelixis has diligence obligations to GlaxoSmithKline with
respect to the Products and Programs. To assure Exelixis’ fulfillment of such obligations, the activities set forth in the Clinical Plan (including any and all amendments thereto) shall always involve [ * ] develop Products. Such efforts
shall include but not be limited to [ * ] such Product. 
  
 (i) The Clinical Plan shall never be amended in any manner that would require Exelixis or Symphony Evolution to perform any assignments or tasks in a manner that would violate any applicable law or regulation. In the event of a
change in any applicable law or regulation, the Development Committee shall consider amending the Clinical Plan to enable Exelixis or Symphony Evolution (as the case may be) to comply fully with such law or regulation. If the Development Committee
does not approve such an amendment, the affected Party shall be excused from performing any activity specified in the Clinical Plan that would violate or result in a violation of any applicable law or regulation. 
  
 4.3 Exelixis Funded Research. Each of Symphony Evolution and
Exelixis hereby agrees that, until the end of the Term, Exelixis, using commercially reasonable methods, may expend its own funds to extend, increase, or otherwise modify, outside the scope of the Clinical Plan, the trials and development activities
run by Exelixis, subject to the approval of the Development Committee (which approval shall not be withheld unless the Development Committee determines in good faith that such changes would have a material adverse effect on the development of the
Program). Such additional Exelixis-supplied funds shall not be included in the calculations used to determine the Program Option Exercise Price (pursuant to Section 11.1 hereof) or the Purchase Price (pursuant to Section 2(b) of the
Purchase Option Agreement). Exelixis agrees that the results of such research and development shall immediately become part of the Licensed Intellectual Property and shall thereafter be subject to the terms of the Operative Documents. Exelixis’
rights pursuant to this Section 4.3 are in addition to, and separate from, its rights pursuant to Sections 8.3(b) and 8.3(c). 
  

	5.	Regulatory Matters. 

  
 5.1 FDA Sponsor. Notwithstanding any governance provision contained herein or in any Operative Document, the Parties agree that, until the
expiration of the unexercised Purchase Option, Exelixis shall be the FDA Sponsor for the Programs (except any Programs which were the subject of a Discontinuation Option that was not exercised by Exelixis). Exelixis shall have the responsibility and
the authority to act as the sponsor and make those decisions and take all actions necessary to assure compliance with all regulatory requirements. Exelixis agrees to be bound by, and perform all obligations set forth in, 21 C.F.R. § 312 related
to its role as the FDA sponsor for the Programs (the “FDA Sponsor”). Notwithstanding anything to the contrary in Article 4 or the Development Committee Charter, Exelixis may discontinue or modify any Program without the
approval of the Development Committee or the Symphony Evolution Board in the event such actions are: (a) triggered by an event that is reportable to the FDA; and (b) reasonably necessary to avoid the imposition of criminal or civil liability.

  
 5.2 Correspondence. Each Party hereto
acknowledges that Exelixis shall be the Party responding to any regulatory correspondence or inquiry. However, each Party shall: (a) notify the other Parties promptly of any FDA or other governmental or regulatory inspection or 
  

 4 
  


 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 inquiry concerning any study or project under the Programs, including, but not limited to, inspections of investigational
sites or laboratories; and (b) forward to the other Parties copies of any correspondence from any regulatory or governmental agency relating to such a study or project, including, but not limited to, Form FD-483 notices and FDA refusal to file,
action or warning letters, even if they do not specifically mention the other Parties. Symphony Evolution shall obtain the written consent of Exelixis, which consent will not be unreasonably withheld, before referring to Exelixis or its Affiliates
in any regulatory correspondence, except to the extent that such reference is required by law or simply refers to the existence of this Agreement or any of the other Operative Documents. Exelixis shall be the Party responsible for responding to or
handling any FDA or regulatory inspection. Exelixis shall notify the Development Committee (i) within twenty-four (24) hours of the commencement of a clinical hold for any Protocol, and (ii) concurrently with its submission to the FDA of any IND
safety reports for the Programs. 
  
 5.3
Inspections. Each Party agrees that during an inspection by the FDA or other Regulatory Authority concerning any study or project under the Programs, it will not disclose information and materials that are not required to be disclosed to
such agency without the prior consent of the other Parties, which consent shall not be unreasonably withheld. Such information and materials include, but are not limited to, the following: (a) financial data and pricing data (including, but not
limited to, the budget and payment schedule); (b) sales data (other than shipment data); and (c) personnel data (other than data as to qualification of technical and professional persons performing functions subject to regulatory requirements).

  
 5.4 Transfer of FDA Sponsorship. 
  
 (a) Within a reasonable time after the expiration of the unexercised
Purchase Option and as of a date to be agreed upon by Symphony Evolution and Exelixis, Exelixis shall cease to act as the FDA sponsor for the Programs for which Exelixis has not exercised the Program Option or Discontinuation Option, and Exelixis
and Symphony Evolution shall, at Symphony Evolution’s expense, take all actions necessary to effect the transfer of the Regulatory Files solely related to such Programs to Symphony Evolution or its designee in accordance with Section 2.7
of the Novated and Restated Technology License Agreement. In conjunction with such transfer, Exelixis shall assign to Symphony Evolution or its designee all of the material agreements to which Exelixis is a Party and which: (i) are related to such
Programs; (ii) provide Exelixis with goods and services (clinical and manufacturing) from third party suppliers and subcontractors; and (iii) are assignable to Symphony Evolution or its designee. Exelixis shall use commercially reasonable efforts to
cause the transfer of any non-assignable material agreements meeting the criteria set forth in (i) and (ii) above. Such efforts shall not include any obligation for Exelixis to incur any out-of-pocket costs in connection with such transfer.

  
 (b) Upon the discontinuation or abandonment of any of
the Protocols pursuant to Section 4.2(f), Exelixis shall have no further obligations with respect to such Protocols under the Operative Documents. Upon the discontinuation or abandonment of any of the Programs pursuant to Section
4.2(g), Exelixis shall have no further obligations with respect to such Programs under the Operative Documents. If such Programs are transferred or licensed to GlaxoSmithKline or a third party in accordance with Section 11.1(f) (such
third party or GlaxoSmithKline, as applicable, the “Transferee”), then Exelixis shall cooperate with

 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 
Symphony Evolution and the Transferee to effect the assignment to the Transferee of the sponsorship to the Regulatory Files with respect to the Program for
which Transferee has acquired rights; provided, however, that Exelixis shall not be obligated to take any action pursuant to this Section 5.4(b) for which it will not receive full reimbursement from Symphony Evolution or another party. The
assignment of such Regulatory Files to the Transferee does not include an assignment of any Licensed Intellectual Property. 
  

	6.	Exelixis’ Obligations. 

  
 6.1 Generally. Exelixis will be responsible for all matters set forth in the Clinical Plan (collectively, the “Exelixis
Obligations”). Each of the Parties agrees that Exelixis will work diligently and use commercially reasonable efforts to develop the Programs in a good scientific manner and, subject to Section 6.2 below, in accordance with the
Clinical Plan, the Clinical Budget, and the terms of this Agreement. 
  
 6.2 Discretion. Exelixis shall have the right to use commercially reasonable discretion in carrying out the Exelixis Obligations including without limitation (a) carrying out day-to-day planning and implementation of
activities under the Clinical Plan; (b) managing regulatory compliance matters, including adverse event reporting; (c) preparing and submitting all regulatory filings; (d) managing clinical research organizations engaged to carry out activities
under the Clinical Plan; (e) managing the clinical trials that have been specified under the Clinical Plan; and (f) maintaining and managing its internal budget in accordance with established internal processes. 
  
 6.3 Subcontracting. Exelixis shall have the right to negotiate
and enter into arms’ length agreements with third parties (including without limitation clinical research organizations and contract manufacturers) for such third parties to perform activities called for or consistent with the Clinical Plan
(each such third party, a “Subcontractor” and each such agreement, a “Subcontracting Agreement”). All such agreements entered into by Exelixis prior to the Closing Date (except for those master
services agreements executed prior to the Closing Date that, only through the subsequent addition of a new work order, change order, project or the like after the Closing Date, become Subcontracting Agreements) are set forth in Schedule 6.3 and
shall be deemed to be acceptable to the Parties in all respects. After the Closing Date, Exelixis shall obtain the approval of the Development Committee before (i) entering into any Subcontracting Agreement that (a) is not [ * ], (b) is not
[ * ], or (c) [ * ] or (ii) amending any Subcontracting Agreement in a manner that would cause such agreement to satisfy the criteria set forth in (a), (b) or (c); provided, however, if Exelixis subcontracts any work under the Programs
through submitting a work order, change order, or the like under an existing master services agreement with a third party (for the avoidance of doubt, such work order or change order shall then become a Subcontracting Agreement), Exelixis shall not
be required to seek the approval from the Development Committee for the submission of such work order or change order or to amend such existing master services agreement unless (1) such work order or change order would alter the terms of an existing
master services agreement that had not previously satisfied the criteria set forth in (a), (b) or (c) in a manner that causes such existing master services agreement to thereafter satisfy the criteria set forth in (a), (b) or (c), in which case
Exelixis would obtain approval of the Development Committee for the submission of such work order or change order or (2) such amendment would take effect concurrently with or after the submission of a 
  

 6 
  


 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 work order or change for work under the Programs and would alter the terms of an existing master services agreement that
had not previously satisfied the criteria set forth in (a), (b) or (c) in a manner that causes such existing master services agreement to thereafter satisfy the criteria set forth in (a), (b) or (c), in which case Exelixis would need to obtain
approval of the Development Committee for the execution of such amendment. Exelixis need not obtain Development Committee approval prior to entering into or amending any other Subcontracting Agreement. Exelixis shall provide the Development
Committee with a copy of each executed Subcontracting Agreement within [ * ] after its execution. The terms of each such agreement shall be deemed the Confidential Information of Exelixis and be subject to the rights and obligations set forth
in the Confidentiality Agreement. Exelixis shall monitor the performance of its Subcontractors and shall use its reasonable discretion to address any Subcontractor performance issues, including without limitation, terminating or amending the
relevant Subcontracting Agreement. Exelixis shall promptly notify the Development Committee with respect to any Subcontractor performance issues that may have a material effect on the Programs. Provided that Exelixis so informs the Development
Committee and follows the Development Committee’s reasonable advice regarding such issues, which may include terminating the Subcontracting Agreement or exercising other remedies, Exelixis shall not be considered in breach of this Agreement or
the other Operative Documents in the event that it is unable to fulfill its obligations under this Agreement on account of a Subcontractor’s failure to perform its obligations pursuant to a Subcontracting Agreement so long as Exelixis (a)
exercised commercially reasonable efforts in supervising such Subcontractor, and (b) used commercially reasonable efforts to mitigate the effects of such failure or to replace such Subcontractor after learning of such Subcontractor’s failure to
perform. 
  
 6.4 Reports. Exelixis shall keep the
Development Committee informed of its activities under the Clinical Plan through regular written reports. At each Quarterly Meeting of the Development Committee, Exelixis shall provide the Development Committee with a summary report of
Exelixis’ activities and developments with respect to the Programs for the preceding quarter. Each such summary report shall be consistent, in terms of topics covered and level of detail provided, with the quarterly report that Exelixis
provides to the Exelixis-GlaxoSmithKline collaboration committee. Once a [ * ], Exelixis shall provide the Development Committee with either (a) a written report that includes the information specified in the next sentence or (b) access to an
Exelixis computer system that contains such information. Each [ * ] written report shall include: (i) a copy of each new Protocol being drafted by Exelixis; (ii) a copy of each standard clinical study progress report received by Exelixis
during the preceding [ * ] from any of the clinical research organizations engaged by Exelixis pursuant to Subcontracting Agreements; (iii) updates regarding (A) [ * ], and (B) [ * ]; (iv) a financial report, in the format
agreed upon by the Parties, itemizing actual spending under the Clinical Plan as well as any variation from planned spending; and (v) if the budget related to a particular Program is altered to the extent that available funding for such Program no
longer appears to be adequate to complete the Program, an updated budget forecast. 
  
 6.5 Staffing. Exelixis shall use commercially reasonable efforts to provide such sufficient and competent staff and Personnel (including, without limitation, such employees or agents of, or independent
contractors retained by, Exelixis) that have the skill and expertise necessary to perform Exelixis’ obligations under the Clinical Plan. Exelixis shall notify Symphony Evolution of any change in key personnel involved in the Programs.

 6.6 QA Audit. During the Term, Exelixis will permit Symphony Evolution’s
representatives, such representatives to be identified by Symphony Evolution in advance and reasonably acceptable to Exelixis, to audit the work performed by Exelixis hereunder and the Exelixis facilities at which such work is conducted to determine
that the project assignment is being conducted in accordance with the agreed upon services (“QA Audits”), which review will last no more than eight (8) hours during regular business hours and will take place no more than once
per year unless (i) there are significant changes to Exelixis’ Standard Operating Procedures, which may require additional QA Audits or (ii) the Development Committee determines additional QA Audits are necessary. Symphony Evolution shall give
Exelixis reasonable advance notice of such QA Audits specifying the scope of the audit, which shall not include work that has previously undergone QA Audits. Symphony Evolution shall reimburse Exelixis for its time associated with QA Audits;
provided, however, that should a particular QA Audit reveal a material deficiency in the work performed, then Symphony Evolution will not be responsible for costs associated with such QA Audit, the work to be re-performed or the costs or expenses
associated with curing any material deficiencies. Symphony Evolution and Exelixis shall meet to discuss the results of the QA Audit and, if required, jointly agree upon any actions that will be required as a result of such audits including defining
material deficiencies to be addressed. Exelixis shall make commercially reasonable efforts to reconcile all such deficiencies found by Symphony Evolution during such QA Audit. 
  
 6.7 Financial Audit. During the Term, Exelixis will permit Symphony Evolution’s representatives, such
representatives to be identified by Symphony Evolution in advance and reasonably acceptable to Exelixis, to verify Exelixis’ receipts and FTE records that are related to Exelixis’ performance of the work under the Programs
(“Financial Audits”), which review shall be conducted during regular business hours and (i) last only as long as necessary to achieve the purpose of such Financial Audit and (ii) will take place no more than once per year,
unless otherwise agreed to by the Parties. Symphony Evolution shall give Exelixis reasonable advance notice of such Financial Audits specifying the scope of the audit, which shall not include work that has previously undergone Financial Audits.
Symphony Evolution shall reimburse Exelixis for its time associated with Financial Audits; provided, however, that should a particular Financial Audit reveal a material discrepancy between such financial records and the reports submitted by Exelixis
to Symphony Evolution for reimbursement purposes, then Symphony Evolution will not be responsible for costs associated with such Financial Audit. Symphony Evolution and Exelixis shall meet to discuss the results of the Financial Audit and, if
required, jointly agree upon any actions that will be required as a result of such audits including defining material discrepancies to be addressed. Exelixis shall make commercially reasonable efforts to reconcile all such discrepancies found by
Symphony Evolution during such Financial Audit.

 8.3 Budget Allocation and Deviations 
  
 (a) Exelixis shall have the discretion to incur out-of-pocket fees, expenses and costs and allocate Exelixis
resources in a manner that is generally consistent with the Clinical Budget, including without limitation deviating from the specific allocations set forth in the Clinical Budget, except as otherwise provided in Sections 8.3(b) or 8.3(c) (as
applicable). In addition, Exelixis shall amend the Clinical Budget accordingly in respect of any such fees, expenses, costs and allocations on a quarterly basis. Exelixis shall be fully compensated for all amounts to which Sections 8.3(b) and
8.3(c) do not apply and all amounts that are approved pursuant to Section 8.3(b) or are included in an amended Clinical Budget. 
  
 (b) If Exelixis reasonably anticipates that the actual cost for a Protocol will exceed that portion of the Clinical Budget allocated for such
Protocol by [ * ] or more in the aggregate, then Exelixis shall contact a Symphony Member to request approval for such additional expenditure. Such Symphony Member shall approve or deny such request within [ * ] of the time when
Exelixis speaks with such Symphony Member via telephone or in person. If such Symphony Member does not inform Exelixis of such approval or denial within such period, then such Symphony Member shall be deemed to have approved such additional
expenditure. If, despite Exelixis’ reasonable efforts to speak with a Symphony Member (which efforts shall include leaving voicemail and email messages for at least two (2) Symphony Members), Exelixis does not succeed in speaking with any
Symphony Member within [ * ] after Exelixis initiated such efforts, such additional expenditure request shall be deemed approved by a Symphony Member unless any Symphony Member informs Exelixis, within [ * ] of the end of such [ *
] period, that such request has been denied. If the Symphony Member approves such additional expenditure, then Exelixis shall be reimbursed pursuant to Sections 8.2 and 8.3 for such additional expenditure. If the Symphony Member denies
such request, then Exelixis may, in its discretion, (i) suspend performance of those incremental activities under the Clinical Plan that are expected to give rise to some or all of such additional expenditure until such time as the Clinical Budget
is amended to include such additional expenditure or (ii) proceed with performance of those incremental activities under the Clinical Plan that are expected to give rise to some or all of such additional expenditure, with the understanding that if
the Clinical Budget is not subsequently amended to include the entirety of such additional expenditures, then Exelixis may not be reimbursed for those resulting expenditures that exceed the Clinical Budget, and further that if the Clinical Budget is
subsequently amended to include some or all of such additional expenditures, then Exelixis shall be reimbursed pursuant to Sections 8.2 and 8.3 for such additional expenditures included in the amended Clinical Budget. If Exelixis incurs
expenditures as described in the preceding sentence for which it is not entitled to be reimbursed by Symphony Evolution pursuant to the preceding sentence, then none of such expenditures shall be included in the calculations used to determine the
Program Option Exercise Price (pursuant to Section 11.1 hereof) or the Purchase Price (pursuant to Section 2(b) of the Purchase Option Agreement). Exelixis agrees that the results of any research and development that it funds pursuant
to this Section 8.3(b) shall immediately become part of the Licensed Intellectual Property and shall thereafter be subject to the terms of the Operative Documents.

 (c) If Exelixis reasonably anticipates that the actual cost in the aggregate of all other
activities covered by the Clinical Budget but not included in those portions of the Clinical Budget allocated to particular Protocols specified in the Clinical Plan, such as CMC, non-clinical and regulatory activities, will exceed that portion of
the Clinical Budget allocated for such activities by [ * ] or more in the aggregate, then Exelixis shall bring such potential additional expenditure to the attention of the Development Committee and Exelixis may, in its discretion, (i)
suspend performance of those incremental activities under the Clinical Plan that are expected to give rise to some or all of such additional expenditure until such time as the Clinical Budget is amended to include such additional expenditure or (ii)
proceed with performance of those incremental activities under the Clinical Plan that are expected to give rise to some or all of such additional expenditure, with the understanding that if the Clinical Budget is not subsequently amended to include
the entirety of such additional expenditures, then Exelixis may not be reimbursed for those resulting expenditures that exceed the Clinical Budget, and further that if the Clinical Budget is subsequently amended to include some or all of such
additional expenditures, then Exelixis shall be reimbursed pursuant to Sections 8.2 and 8.3 for such additional expenditures included in the amended Clinical Budget. If Exelixis incurs expenditures as described in the preceding sentence for
which it is not entitled to be reimbursed by Symphony Evolution pursuant to the preceding sentence, then none of such expenditures shall be included in the calculations used to determine the Program Option Exercise Price (pursuant to Section
11.1 hereof) or the Purchase Price (pursuant to Section 2(b) of the Purchase Option Agreement). Exelixis agrees that the results of any research and development that it funds pursuant to this Section 8.3(c) shall immediately become
part of the Licensed Intellectual Property and shall thereafter be subject to the terms of the Operative Documents. 
  
 (d) If the Clinical Budget is not amended to include any additional expenditure brought to the attention of the Development Committee pursuant to
Section 8.3(b) or 8.3(c) and Exelixis does not elect to fund such additional expenditures, then the Development Committee shall recommend and the Symphony Evolution Board shall approve an amendment of the Clinical Plan that adjusts the scope
of the work to that which can be reasonably accomplished within the constraints of the Clinical Budget. Under no circumstances shall Exelixis be obligated to incur out-of-pocket fees, expenses or costs or to utilize Exelixis resources in connection
with its performance of the work under the Programs for which Exelixis will not be reimbursed by Symphony Evolution. 
  
 8.4 Employee Benefits. Symphony Evolution shall not be responsible for providing or paying any benefits (including, but not limited to,
unemployment, disability, insurance, or medical, and any pension or profit sharing plans) to Exelixis or to any employees of Exelixis or any persons retained or used by Exelixis to perform activities pursuant to the Clinical Plan, including
independent contractors, Subcontractors and agents (collectively, “Exelixis Personnel”). As to Exelixis or any Exelixis Personnel, Symphony Evolution shall not be responsible for: (a) any federal, state or local income tax
withholding; (b) “FICA” contributions; (c) contributions to state disability funds or liability funds or similar withholdings; (d) payment of any overtime wages; (e) workers’ compensation; or (f) compliance with any laws, rules or
regulations governing employees. Exelixis agrees that, as between Symphony Evolution and Exelixis, Exelixis is and will continue to be solely responsible for: (i) all matters relating to the payment of compensation and provision of benefits to
Exelixis Personnel; and (ii) compliance with all applicable laws, rules and regulations governing Exelixis’ employees.

 8.5 Taxes on Program Option, Discontinuation Option and Sale to Third Party. In the event
of an exercise of the Program Option, an exercise of the Discontinuation Option or a sale of a discontinued or abandoned Program to GlaxoSmithKline or other third party, any and all corporate taxes required to be paid by Symphony Evolution as a
result of the receipt of the proceeds of such Program Option, Discontinuation Option or sale to a third party shall be satisfied by Symphony Evolution from such proceeds of such Program Option, Discontinuation Option or sale, as applicable.

  

	9.	Covenants. 

  
 9.1 Mutual Covenants. Each of Exelixis and Symphony Evolution covenants and agrees that, with respect to the Programs and any other rights
and obligations set forth in the Operative Documents, it shall: 
  
 (a) perform all of its obligations pursuant to this Agreement in material compliance with: (i) all applicable federal and state laws, statutes, rules, regulations and orders (including all applicable approval and qualification
requirements thereunder), including, without limitation, the Federal Food, Drug and Cosmetic Act and the regulations promulgated pursuant thereto; (ii) all applicable good clinical practices and guidelines; (iii) all applicable standard operating
procedures; (iv) all applicable Protocols; and (v) the provisions of this Agreement; 
  
 (b) keep complete, proper and separate books of record and account, including a record of all costs and expenses incurred, all charges made, all credits made and received, and all income derived in connection
with the operation of its business, all in accordance with GAAP; 
  
 (c) not employ (or, to the best of its knowledge without further duty of inquiry, shall not use any contractor or consultant that employs) any individual or entity debarred by the FDA (or subject to a similar sanction of any other
Regulatory Authority), or, to the best of its knowledge without further duty of inquiry, any individual who or entity which is the subject of an FDA debarment investigation or proceeding (or similar proceeding of any other Regulatory Authority), in
the conduct of the Programs; 
  
 (d) promptly deliver to
the other, upon receipt thereof, notice of all actions, suits, investigations, litigation and proceedings before any Governmental Authority, which would reasonably be expected to affect such Party’s ability to perform its obligations under this
Agreement; 
  
 (e) upon it receiving knowledge of a
material event or development with respect to any Program, such Party shall notify the other Party in writing within [ * ] of the receipt of such knowledge by any executive officer of such Party, provided that the failure to provide such
notice shall not impair or otherwise be deemed a waiver of any rights any Party may have arising from such material event. Furthermore, the provision of such notice of material event or development shall not be deemed an admission by the Party
providing such notice of its breach of any of its covenants, representations or obligations under the Operative Documents; and

 (f) with reasonable promptness, deliver to the other such data and information relating to the
ability of such Person to perform its obligations hereunder as from time to time may be reasonably requested by the other (subject to the maintenance of the confidentiality of any such information by the receiving Party). For the avoidance of doubt,
this Section 9.1(f) includes Exelixis’ obligations to provide financial and other necessary information to Symphony Evolution and the Manager to enable Symphony Evolution to fulfill its obligations to Exelixis under Section 5(d)
of the Purchase Option Agreement, and to enable the Manager to fulfill its obligations to Symphony Evolution and Exelixis under Sections 5(a) and 5(b) of the Management Services Agreement. 
  

	10.	Confidentiality. 

  
 10.1 Confidentiality Agreement. It is understood that during the course of this Agreement each of the Parties shall be bound by the terms of
the Confidentiality Agreement. In addition, the Parties’ employees, subcontractors and agents shall be bound by terms substantially similar to the Confidentiality Agreement. The foregoing shall not be construed to require Exelixis to amend or
supplement any of the agreements it entered into prior to the Closing Date, even if the confidentiality provisions in such agreements do not satisfy the foregoing requirement. 
  
 10.2 Permitted Disclosure of Information. The Parties agree that Exelixis shall have access to, and may use
and disclose the Clinical Plan and any existing or newly generated data or intellectual property developed with respect to the Programs (i) to GlaxoSmithKline or the Exelixis-GlaxoSmithKline Collaboration Committee in accordance with the mutual
agreements of Exelixis and GlaxoSmithKline, (ii) to obtain the assistance of one or more third parties to develop and/or commercialize the Programs subject to the terms of this Agreement, the other Operative Documents and appropriate confidentiality
agreements pursuant to Section 10.1 or as approved by Symphony Evolution, and (iii) through press releases, public presentations or other appropriate public disclosures; provided that all such disclosure under this Section 10.2
shall be subject to the terms of the Confidentiality Agreement. 
  

	11.	Options and Licensing. 

  
 11.1 Program Option. 
  
 (a) In consideration for entering into the Operative Documents to which both Exelixis and Symphony Evolution are parties, Symphony Evolution hereby
grants Exelixis an exclusive option (the “Program Option”) to purchase the rights to one Program at any time during the period (the “Program Option Period”) after Exelixis has, by itself or through its
subcontractor(s), [ * ] and before the earlier of (A) the termination of the Term, and (B) the eighteenth (18th) month anniversary of the Closing Date, in accordance with this Section 11.1. 
  
 (b) Exelixis may exercise the Program Option by delivery of a written
notice (the “Program Option Exercise Notice”) during the Program Option Period. The Program

 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 Option Exercise Notice shall be delivered on a Business Day to Holdings and Symphony Evolution and shall be irrevocable
once delivered. The date on which the Program Option Exercise Notice is first delivered to Holdings and Symphony Evolution is referred to as the “Program Option Exercise Date.” The Program Option Exercise Notice shall specify
a closing date for the settlement of the Program Option, which date shall not be less than [ * ]s after the Program Option Exercise Date. 
  
 (c) The exercise price (the “Program Option Exercise Price”) shall be an amount equal to the sum of (A) [ * ], plus
(B) an amount equal to [ * ], provided that such return thereon shall be calculated starting from [ * ] and through the Program Option Closing Date. In the event that, subsequent to its exercise of the Program Option, Exelixis
exercises the Purchase Option under the Purchase Option Agreement, the Purchase Option Exercise Price shall be reduced by an amount equal to the Program Option Exercise Price. 
  
 (d) The entire amount of the Program Option Exercise Price shall be paid in cash on the date specified in the Program
Option Exercise Notice (the “Program Option Closing Date”). 
  
 (e) Promptly after the Program Option Closing Date, the Parties hereby agree to amend the Novated and Restated Technology License Agreement and such other Operative Documents as may be required to reflect that
the Licensed Intellectual Property related to the applicable Program shall thereafter be the sole and exclusive property of Exelixis or its assignee or licensee. 
  
 (f) Within a reasonable time after the Program Option Closing Date, Symphony Evolution shall transfer and deliver to
Exelixis any and all materials, documents, files and other information relating to the applicable compound and Product (or, where necessary, copies thereof if such materials, documents, files or other information also relate to Programs (including
compounds and Products) that are not the subject of the Program Option), including without limitation any and all administrative files relating to the applicable compound and Product, and, to the extent applicable, any and all clinical and protocol
results, analytical methodologies, bulk and final product manufacturing processes, batch records, vendor information, validation documentation, regulatory documentation, patent information, regulatory filings, transfer of information related to
regulatory information and filings, pre-clinical and clinical data, adverse event data, regulatory correspondence, analyses, and manufacturing data. 
  
 (g) In the event that, following the Program Option Closing Date, either Party objects to the calculation of the portion of the Funded Capital
expended on the development of the applicable Program as of the Program Option Closing Date used to determine the final Program Option Exercise Price (the “Program Funding”), then, within [ * ] of the Program Option
Closing Date, such objecting party shall provide written notice to the other party (a “Program Purchase Price Dispute Notice”) specifying the amount disputed and the basis for the dispute, together with supporting
documentation reflecting the analysis of and justification for any re-computation made. In the event that a Program Purchase Price Dispute Notice is issued by either party, such dispute shall be resolved in accordance with the terms of Section
11.1(h). The Program Option Exercise Price shall be final, binding and conclusive, shall be non-appealable and shall not be subject to further review if the disputing party does not deliver a

 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 Program Purchase Price Dispute Notice within such [ * ] period. For the avoidance of doubt, nothing in this
Section 11.1(g) shall restrict or delay the Parties’ performance of those activities identified in this Agreement or the Novated and Restated Technology License Agreement as taking place following the exercise of the Program Option.

  
 (h) Program Option Exercise Price Adjustment.

  
 (i) In the event that either Party delivers to the
other a Program Purchase Price Dispute Notice within the time limit set forth in Section 11.1(g), then both Parties shall make good faith efforts to resolve any dispute relating to the calculation of the Program Funding through negotiations
for a period of [ * ] following the date on which a Program Purchase Price Dispute Notice is delivered. If the Parties agree on the calculation of the Program Funding (or a revision thereto) before or within such [ * ] period, or the
calculation of the Program Option Exercise Price becomes final pursuant to Section 11.1(g), and (x) the recalculated Program Funding results in a recalculated Program Option Exercise Price (including as revised through negotiations) that is
less than the Program Option Exercise Price paid on the Program Option Closing Date, then Symphony Evolution shall promptly, and in any event within [ * ] of the date on which the Program Option Exercise Price recalculation becomes final, pay
to Exelixis the amount by which the recalculated Program Option Exercise Price is less than Program Option Exercise Price paid on the Program Option Closing Date, or (y) the recalculated Program Funding results in a recalculated Program Option
Exercise Price (including as revised through negotiations) that is greater than the Program Option Exercise Price paid on the Program Option Closing Date, then Exelixis shall promptly, and in any event within [ * ] of the date on which the
recalculated Program Option Exercise Price becomes final, pay to Symphony Evolution the amount by which the recalculated Program Option Exercise Price is greater than the Program Option Exercise Price paid on the Program Option Closing Date. In the
event that neither of the conditions set forth in the previous clauses (x) and (y) exist, then no payment shall be made. 
  
 (ii) To the extent that any matter remains unresolved following negotiations during such [ * ] period (as determined by notice by any party
to the other party), the Parties shall jointly select an independent accountant of recognized national standing to resolve any remaining disagreements, which independent accountant shall not have provided services to either of the Parties or any of
their respective Affiliates during the five-year period preceding the date of its selection (the “Independent Accountant”). The Parties shall use their respective commercially reasonable efforts to cause such Independent
Accountant to make its determination of the Program Option Exercise Price (the “Final Program Option Exercise Price”) within [ * ] of accepting its selection. The decision of the Independent Accountant shall be a
final, binding and conclusive resolution of the parties’ dispute, shall be non-appealable and shall not be subject to further review. The costs and expenses of the Independent Accountant shall be split between the Parties in proportion to the
difference between the Final Program Option Exercise Price and the Program Option Exercise Price (recalculated, if applicable, pursuant to Section 11.1(h)(i)). Notwithstanding the foregoing, in any case, each Party shall be responsible for
the payment of its respective costs and expenses, including any attorneys’ and accountants’ fees (other than any accountants’ fees payable to the Independent Accountant, which shall be split between the Parties in accordance with this
Section 11.1(h)) incurred in 
  

 15 
  


 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 connection with the dispute. If the Final Program Option Exercise Price is less than the Program Option Exercise Price
paid on the Program Option Closing Date, then Symphony Evolution shall promptly, and in any event within [ * ] of the date on which the Independent Accountant makes its determination of the Final Program Option Exercise Price, pay to Exelixis
the amount by which the Final Program Option Exercise Price is less than the Program Option Exercise Price paid on the Program Option Closing Date. If the Final Program Option Exercise Price is greater than the Program Option Exercise Price paid on
the Program Option Closing Date, then Exelixis shall promptly, and in any event within [ * ] of the date on which the Independent Accountant makes its determination of the Final Program Option Exercise Price, pay to Symphony Evolution the
amount by which the Final Program Option Exercise Price is greater than the Program Option Exercise Price paid on the Program Option Closing Date. In the event that neither of the conditions set forth in the previous two sentences exist, then no
payment shall be made. 
  
 11.2 Discontinuation Option.

  
 (a) A Program may only be discontinued or abandoned in
accordance with Section 4.2(g). In the event of such a Program discontinuation or abandonment during the Term, (i) Symphony Evolution shall so notify Exelixis and GlaxoSmithKline promptly and in writing of such discontinuance or abandonment,
and (ii) Exelixis shall have the right and option (the “Discontinuation Option”), exercisable for [ * ] after receipt of written notice from Symphony Evolution of such discontinuance or abandonment, to buy back the
Licensed Intellectual Property related to such discontinued or abandoned Program for a price (the “Discontinuation Price”) to be determined between the Parties, or, if the Parties are unable to come to a resolution, for a
Discontinuation Price determined in accordance with Section 11.2(c) hereof. If the Discontinuation Price is determined in accordance with Section 11.2(c), then such [ * ] period shall be extended by the time needed by the
Experts for such determination. Any Discontinuation Price paid under this Section 11.2(a) shall reduce the Purchase Option Exercise Price in the amount of such payment. 
  
 (b) Following the expiration of the Discontinuation Option without exercise by Exelixis, if Symphony Evolution
proposes to transfer or license the discontinued Program to a third party, then (i) Symphony Evolution shall so notify GlaxoSmithKline (with a copy to Exelixis) of its intention promptly and in writing, and (ii) GlaxoSmithKline shall have, for a
period of [ * ] after receipt of such written notice, the exclusive right to negotiate with Symphony Evolution for the acquisition or the license of the rights to such discontinued or abandoned Program. At GlaxoSmithKline’s request,
Symphony Evolution shall negotiate in good faith with GlaxoSmithKline the terms of such acquisition or license and upon any agreement of terms, shall enter into a binding agreement setting forth such terms. Following such [ * ] period,
Symphony Evolution may transfer or license such rights relating to such discontinued or abandoned Program to any third party. If Symphony Evolution so transfers or licenses such Program rights before the termination of the Term, all amounts that
Symphony Evolution receives from such third party shall reduce the Purchase Option Exercise Price in the amount of such payment. During the Term, under no circumstances may Symphony Evolution or Exelixis (unless Exelixis has exercised a
Discontinuation Option in respect of such Program) reinitiate work on a discontinued or abandoned Program.

 (c) If Exelixis and Symphony Evolution cannot agree on the Discontinuation Price, with respect to
Section 11.2(a), Exelixis and Symphony Evolution shall each appoint a nationally recognized expert in the field of pharmaceutical technology and licensing (each, an “Expert”) (that, in each case, has had no prior
dealings with either of Exelixis and Symphony Evolution in the preceding twelve (12) months), and such two (2) Experts shall appoint a third Expert. In accordance with this Section 11.2(c), such three (3) Experts shall jointly determine, or,
if all three (3) Experts shall not be able to agree on such Discontinuation Price as applicable, two (2) of such three (3) Experts shall jointly determine, the Discontinuation Price, which determination shall be made within [ * ] of the
appointment of the third Expert and, absent manifest error, shall be (i) binding and conclusive and (ii) the Discontinuation Price at which the Discontinuation Option shall be exercised by Exelixis. All costs and expenses incurred in appointing the
Experts shall be shared equally between Exelixis and Symphony Evolution. 
  
 11.3 Post-Term. Following the expiration or termination of the Term without exercise of the Purchase Option by Exelixis, Symphony Evolution may offer to transfer or license any of the Programs for which
Exelixis has not exercised its Program Option or Discontinuation Option to any third party, provided that, if Symphony Evolution proposes to transfer or license any such Program (other than a Program that was the subject of a Discontinuation
Option) to a third party, then (a) Symphony Evolution shall so notify GlaxoSmithKline (with a copy to Exelixis) of its intention promptly and in writing, and (b) GlaxoSmithKline shall have, for a period of [ * ] after receipt of such written
notice, the exclusive right to negotiate with Symphony Evolution for the acquisition or the license of the rights to any such Program (and Licensed Intellectual Property relating thereto, including without limitation Symphony Evolution
Enhancements), and for an additional [ * ] the right to negotiate on a non-exclusive basis for such rights. If such [ * ] period ends without Symphony Evolution and GlaxoSmithKline entering into an agreement governing the terms and
conditions of such acquisition or license, then Symphony Evolution may subsequently transfer or license such rights relating to such Program to any third party; provided, however, that if any new data is gained subsequent to such [
* ] period relating to a Program, Symphony shall, as soon as practicable thereafter and subject to the Operative Documents and customary confidentiality restrictions, disclose such new data to GlaxoSmithKline, to enable GlaxoSmithKline to
determine if it is interested in acquiring or licensing such Program within an additional [ * ] period, but only if Symphony Evolution has not, as of such time, entered into a binding agreement (including a binding letter of intent) for the
transfer or license of such Program to a third party.

 rules), Exelixis has all requisite corporate power and authority to execute, deliver and perform its obligations under
this Agreement and the Novated and Restated Technology License Agreement and to consummate the transactions contemplated thereby. The execution, delivery and performance by Exelixis of this Agreement and the Novated and Restated Technology License
Agreement and the consummation of the transactions contemplated thereby have been duly and validly authorized by all necessary action required on the part of Exelixis (other than as set forth in the Operative Documents, and in respect of the
exercise of the Program Option pursuant to Section 11.1 hereof and the Discontinuation Option pursuant to Section 11.2 hereof (which are subject to future approval by Exelixis’ board of directors and potentially Exelixis’
stockholders if required by applicable NASDAQ or other stock exchange rules)), and no other proceedings on the part of Exelixis are necessary to authorize this Agreement or the Novated and Restated Technology License Agreement or for Exelixis to
perform its obligations under this Agreement or the Novated and Restated Technology License Agreement. This Agreement and the Novated and Restated Technology License Agreement constitute the lawful, valid and legally binding obligations of Exelixis,
enforceable in accordance with their terms, except as the same may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and general equitable
principles regardless of whether such enforceability is considered in a proceeding at law or in equity. 
  
 (c) No Violation or Conflict. The execution, delivery and performance of this Agreement and the Novated and Restated Technology License
Agreement and the transactions contemplated thereby do not and will not (i) violate, conflict with or result in the breach of any provision of the Organizational Documents of Exelixis, (ii) conflict with or violate any law or Governmental Order
applicable to Exelixis or any of its assets, properties or businesses, or (iii) conflict with, result in any breach of, constitute a default (or event that with the giving of notice or lapse of time, or both, would become a default) under, require
any consent under, or give to others any rights of termination, amendment, acceleration, suspension, revocation or cancellation of, or result in the creation of any Encumbrance on any of the assets or properties of Exelixis, pursuant to, any note,
bond, mortgage or indenture, contract, agreement, lease, sublease, license, permit, franchise or other instrument or arrangement to which Exelixis is a party except, in the case of clauses (ii) and (iii), to the extent that such conflicts, breaches,
defaults or other matters would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Exelixis. 
  
 (d) Governmental Consents and Approvals. Other than any HSR Act Filings and Additional Regulatory Filings which, if the Program Option or
Discontinuation Option is exercised by Exelixis, will be obtained on or prior to the Program Option Closing Date or Discontinuation Option Closing Date, the execution, delivery and performance of this Agreement and the Novated and Restated
Technology License Agreement by Exelixis do not, and the consummation of the transactions contemplated thereby do not and will not, require any Governmental Approval which has not already been obtained, effected or provided, except with respect to
which the failure to so obtain, effect or provide would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Exelixis. 
  
 (e) Litigation. There are no actions by or against Exelixis pending before any Governmental Authority or, to

Adverse Effect on Exelixis. There are no pending or, to the knowledge of Exelixis, threatened actions, to which Exelixis is a party (or is threatened to be named as a party) to set aside, restrain, enjoin or prevent the execution, delivery or
performance of this Agreement or the Operative Documents or the consummation of the transactions contemplated hereby or thereby by any party hereto or thereto. Exelixis is not subject to any Governmental Order (nor, to the knowledge of Exelixis, is
there any such Governmental Order threatened to be imposed by any Governmental Authority) that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Exelixis or a material adverse effect on the
Programs. 
  
 (f) No Contracts. Except as disclosed
on Schedule 12.1(f) hereto, there are no material contracts between Exelixis and any third party, including contractors, manufacturers or suppliers, used with or otherwise necessary for the Programs. With respect to the contracts disclosed on
Schedule 12.1(f) hereto, the absence of such contracts (due to the inability or impracticability of assigning such contracts to Symphony Evolution following a termination of this Agreement without the exercise of the Purchase Option) would
not have a material adverse effect on any of the Programs or on Symphony Evolution’s rights under the Novated and Restated Technology License Agreement. 
  
 12.2 Symphony Evolution Representations and Warranties. Symphony Evolution hereby represents and warrants to Exelixis that, as of the
Effective Date:

Symphony Evolution are necessary to authorize this Agreement or the Novated and Restated Technology License Agreement or for Symphony Evolution to perform its obligations under this Agreement or the Novated and Restated Technology License Agreement.
This Agreement and the Novated and Restated Technology License Agreement constitute the lawful, valid and legally binding obligations of Symphony Evolution, enforceable in accordance with its terms, except as the same may be limited by applicable

the aggregate, reasonably be expected to have a Material Adverse Effect on Symphony Evolution. 
  
 (d) Governmental Consents and Approvals. The execution, delivery and performance of this Agreement and the Novated and Restated Technology License Agreement by Symphony Evolution do not, and the
consummation of the transactions contemplated thereby do not and will not, require any Governmental Approval which has not already been obtained, effected or provided, except with respect to which the failure to so obtain, effect or provide would
not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Symphony Evolution. 
  
 (e) Litigation. There are no actions by or against Symphony Evolution pending before any Governmental Authority or, to the knowledge of
Symphony Evolution, threatened to be brought, by or before any Governmental Authority that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Symphony Evolution. There are no pending or, to the
knowledge of Symphony Evolution, threatened actions to which Symphony Evolution is a party (or is threatened to be named as a party) to set aside, restrain, enjoin or prevent the execution, delivery or performance of this Agreement or the Operative
Documents or the consummation of the transactions contemplated hereby or thereby by any party hereto or thereto. Symphony Evolution is not subject to any Governmental Order (nor, to the knowledge of Symphony Evolution, is there any such Governmental
Order threatened to be imposed by any Governmental Authority) that would, individually or in the aggregate reasonably be expected to have a Material Adverse Effect on Symphony Evolution or a material adverse effect on the Programs. 
  

	13.	Relationship Between Exelixis and Symphony Evolution. Nothing contained in this Agreement or any acts or omissions hereunder shall constitute or be construed so as to
create any joint venture or partnership relationship between Exelixis and Symphony Evolution, and the Parties acknowledge and agree that Exelixis is acting as an independent contractor in the performance of its obligations under this Agreement.

(iii) arranged for an appropriate senior executive of the Surviving Entity to [ * ], including, but not limited to, the Surviving Entity’s commitment to [ * ] under the Operative Documents, as well as the strategic importance of
the [ * ] to the Surviving Entity. 
  

	15.	No Restrictions; Indemnification. 

  
 15.1 No Restrictions. Nothing in this Agreement shall limit or restrict the right of any director, officer or employee of Exelixis or any director,
officer, or employee of any of its subsidiaries or its Affiliates to engage in any other business or to devote his or her time and attention to the management or other aspects of any other business, whether of a similar or dissimilar nature, nor

 (a) To the greatest extent permitted by applicable law, Exelixis shall indemnify and hold harmless Symphony Evolution and RRD and each of their
respective Affiliates, officers, directors, employees, agents, members, managers, successors and assigns (each, a “Symphony Indemnified Party”), and Symphony Evolution shall indemnify and hold harmless Exelixis, and its
Affiliates and each of their respective officers, directors, employees, agents (other than Subcontractors), members, managers, successors and assigns (each, an “Exelixis Indemnified Party”), from and against any and all
claims, losses, diminution in value, costs, interest, awards, judgments, penalties, fees (including reasonable fees for attorneys and other professionals), court costs, liabilities, damages and expenses incurred by any Symphony Indemnified Party or
Exelixis Indemnified Party (irrespective of whether any such Indemnified Party is a party to the action for which indemnification hereunder is sought) (hereinafter, a “Loss”) as a result of, or arising out of, or relating to
any and all third party suits, claims, actions, proceedings or demands based upon: 
  
 (i) in the case of Exelixis being the Indemnifying Party, (A) any breach of any representation or warranty made by Exelixis herein or in any certificate, instrument or document delivered hereunder, (B) any
breach of any covenant, agreement or obligation of Exelixis contained herein, or in any certificate, instrument or document delivered hereunder, except to the extent such covenant, agreement or obligation relates to Exelixis’ performance under
the Development Plan, (C) any gross negligence or willful misconduct of Exelixis (and not that of its Subcontractors) in connection with Exelixis’ performance of its obligations under this Agreement (including the Development Plan), (D) any

 Subcontractor’s failure to follow applicable law, regulations or protocols, in each case solely to the extent that
such Subcontractor is obligated pursuant to the applicable Subcontracting Agreement to indemnify Exelixis for such Loss, it being understood and agreed by the Parties that (1) if both Symphony Indemnified Parties and Exelixis Indemnified Parties
incur Losses addressed in this Section 15.2(a)(i)(E) and the total amount received from such Subcontractor as a result of such indemnification obligation is less than the total applicable Losses suffered by the Symphony Indemnified Parties
and Exelixis Indemnified Parties, then Exelixis shall distribute among the relevant Symphony Indemnified Parties a total amount equal to [ * ] of the such amount received from such Subcontractor (which amount shall be decreased to the extent
that the total applicable Losses suffered by the Symphony Indemnified Parties is less that such [ * ] or increased to the extent that the total applicable Losses suffered by the Exelixis Indemnified Parties is less than the [ * ]
otherwise to be retained by Exelixis hereunder) and (2) if the Symphony Indemnified Parties and Exelixis Indemnified Parties are held to be joint and severally liable with respect to any Losses under this Section 15.2(a)(i)(E) and such Losses
exceed the total amount received from such Subcontractor as a result of such indemnification obligation, the recovery from such Subcontractor shall first be applied to such Losses and notwithstanding the joint and several liability judgment, the
remainder of such Losses shall be shared equally by Symphony Evolution and Exelixis, (F) activities that are solely related to Exelixis funded research pursuant to Section 4.3, provided that such research pertains to a new Protocol developed
by Exelixis, rather than an extension, continuation or modification of any Protocol included in the Development Plan, or (G) in the event Licensor exercises a Program Option or Discontinuation Option for a Program, any action undertaken and/or
performed by or on behalf of Licensor after the Program Option Closing Date or Discontinuation Closing Option Date and relating to the Product that was the subject of such Program (including the development, manufacture, use, handling, storage, sale
or other disposition of such Product); in each case, except (1) with respect to Losses for which Exelixis is entitled to indemnification under this Article 15 or (2) to the extent such Loss arises from the gross negligence or willful
misconduct of a Symphony Indemnified Party; and 
  
 (ii)
in the case of Symphony Evolution being the Indemnifying Party, (A) any breach of any representation or warranty made by Symphony Evolution herein or in any certificate, instrument or document delivered hereunder, (B) any breach of any covenant,
agreement or obligation of Symphony Evolution contained herein or in any certificate, instrument or document delivered hereunder, (C) any and all activities by or on behalf of the Parties under the Development Plan (including (1) any activities
performed by RRD pursuant to the Management Services Agreement and (2) any claim arising out of any condition caused by XL647, XL784, XL999 or the Products after the Closing Date but prior to the expiration of the Term), (D) any gross negligence or
willful misconduct of Symphony Evolution (and not that of its subcontractors) in connection with Symphony Evolution’s performance of its obligations under this Agreement, or (E) the development, manufacture, use, handling, storage, sale or
other disposition of the Products (including in the course of conducting the Programs) during the Term (except with respect to the development, manufacture, use, handling, storage, sale or other disposition, after Exelixis’ exercise of the
Program Option or Discontinuation Option as applicable, of Products covered under Section 15.2(a)(i)(G)); in each case, except (1) with respect to Losses for which Symphony Evolution is entitled to indemnification under this Article 15, or
(2) Losses deemed to have arisen from the breach by Exelixis of any covenant, agreement

 or obligation under this Agreement that relates to Exelixis’ performance under the Development Plan, as determined
by a court, arbitrator or pursuant to a settlement agreement, or (3) to the extent such Loss arises from the gross negligence or willful misconduct of an Exelixis Indemnified Party. Solely for the purposes of claims arising under (C) above,
Subcontractors shall also be deemed to be Exelixis Indemnified Parties. 
  
 To the
extent that the foregoing undertaking by Exelixis or Symphony Evolution may be unenforceable for any reason, such Party shall make the maximum contribution to the payment and satisfaction of any Loss that is permissible under applicable law.

  
 (b) Notice of Claims. Any Indemnified Party that
proposes to assert a right to be indemnified under this Section 15.2 shall notify Exelixis or Symphony Evolution, as applicable (the “Indemnifying Party”), promptly after receipt of notice of commencement of any
action, suit or proceeding against such Indemnified Party (an “Indemnified Proceeding”) in respect of which a claim is to be made under this Section 15.2, or the incurrence or realization of any Loss in respect of
which a claim is to be made under this Section 15.2, of the commencement of such Indemnified Proceeding or of such incurrence or realization, enclosing a copy of all relevant documents, including all papers served and claims made, but the
omission so to notify the applicable Indemnifying Party promptly of any such Indemnified Proceeding or incurrence or realization shall not relieve (x) such Indemnifying Party from any liability that it may have to such Indemnified Party under this
Section 15.2 or otherwise, except, as to such Indemnifying Party’s liability under this Section 15.2, to the extent, but only to the extent, that such Indemnifying Party shall have been prejudiced by such omission, or (y) any
other indemnitor from liability that it may have to any Indemnified Party under the Operative Documents. 
  
 (c) Defense of Proceedings. In case any Indemnified Proceeding shall be brought against any Indemnified Party, it shall notify the
applicable Indemnifying Party of the commencement thereof as provided in Section 15.2(b), and such Indemnifying Party shall be entitled to participate in, and provided such Indemnified Proceeding involves a claim solely for money damages and
does not seek an injunction or other equitable relief against the Indemnified Party and is not a criminal or regulatory action, to assume the defense of, such Indemnified Proceeding with counsel reasonably satisfactory to such Indemnified Party, and
after notice from such Indemnifying Party to such Indemnified Party of such Indemnifying Party’s election so to assume the defense thereof and the failure by such Indemnified Party to object to such counsel within [ * ] following its
receipt of such notice, such Indemnifying Party shall not be liable to such Indemnified Party for legal or other expenses related to such Indemnified Proceedings incurred after such notice of election to assume such defense except as provided below
and except for the reasonable costs of investigating, monitoring or cooperating in such defense subsequently incurred by such Indemnified Party reasonably necessary in connection with the defense thereof. Such Indemnified Party shall have the right
to employ its counsel in any such Indemnified Proceeding, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless: 
  

(i) the employment of counsel by such Indemnified Party at the expense of the applicable Indemnifying Party has been authorized in writing by
such Indemnifying Party; 
  

 23 
  


 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 








 (ii) such Indemnified Party shall have reasonably concluded in its good faith (which conclusion
shall be determinative unless a court determines that such conclusion was not reached reasonably and in good faith) that there is or may be a conflict of interest between the applicable Indemnifying Party and such Indemnified Party in the conduct of
the defense of such Indemnified Proceeding or that there are or may be one or more different or additional defenses, claims, counterclaims, or causes of action available to such Indemnified Party (it being agreed that in any case referred to in this
clause (ii) such Indemnifying Party shall not have the right to direct the defense of such Indemnified Proceeding on behalf of the Indemnified Party); 
  
 (iii) the applicable Indemnifying Party shall not have employed counsel reasonably acceptable to the Indemnified Party to assume the defense of
such Indemnified Proceeding within a reasonable time after notice of the commencement thereof (provided, however, that this clause shall not be deemed to constitute a waiver of any conflict of interest that may arise with respect to
any such counsel); or 
  
 (iv) any counsel employed by the
applicable Indemnifying Party shall fail to timely commence or diligently conduct the defense of such Indemnified Proceeding; 
  
 in each of which cases the fees and expenses of counsel for such Indemnified Party shall be at the expense of such Indemnifying Party. Only one counsel
shall be retained by all Indemnified Parties with respect to any Indemnified Proceeding, unless counsel for any Indemnified Party reasonably concludes in good faith (which conclusion shall be determinative unless a court determines that such
conclusion was not reached reasonably and in good faith) that there is or may be a conflict of interest between such Indemnified Party and one or more other Indemnified Parties in the conduct of the defense of such Indemnified Proceeding or that
there are or may be one or more different or additional defenses, claims, counterclaims, or causes or action available to such Indemnified Party. 
  
 (d) Settlement. Without the prior written consent of such Indemnified Party, such Indemnifying Party shall not settle or compromise, or
consent to the entry of any judgment in, any pending or threatened Indemnified Proceeding, unless such settlement, compromise, consent or related judgment (i) includes an unconditional release of such Indemnified Party from all liability for Losses
arising out of such claim, action, investigation, suit or other legal proceeding, (ii) provides for the payment of money damages as the sole relief for the claimant (whether at law or in equity), (iii) involves no finding or admission of any
violation of law or the rights of any Person by the Indemnified Party, and (iv) is not in the nature of a criminal or regulatory action. No Indemnified Party shall settle or compromise, or consent to the entry of any judgment in, any pending or
threatened Indemnified Proceeding in respect of which any payment would result hereunder or under the Operative Documents without the prior written consent of the Indemnifying Party, such consent not to be unreasonably conditioned, withheld or
delayed.

within the authority of) Exelixis (and such Subcontractors and vendors it may retain) hereunder, and (b) supervising, compensating or discharging, or any other liability to or with respect to, any vendor retained by Exelixis (or, in the case of a
vendor engaged by both RRD and Exelixis, to and for such vendor to the extent that such vendor performs services for Exelixis), except that RRD shall make payments out of an account held in the name of Symphony Evolution to reimburse Exelixis, in

the Operative Documents, and Exelixis does not cure such breach within [ * ] after its receipt of written notice thereof from Symphony Evolution, then Symphony Evolution may by subsequent written notice to Exelixis terminate this Agreement.
Such cure period may be extended to [ * ] if (i) Exelixis believes that such breach can be cured within [ * ] of Exelixis’ receipt of Symphony Evolution’s written notice of such breach (and notifies Symphony Evolution in

been incurred or become uncancellable prior to such termination). 
  

	18.	Miscellaneous. 

  
 18.1 No Petition. Exelixis covenants and agrees that, prior to the date which is one (1) year and one (1) day after the expiration of the
