MASTER CONTRACT SERVICES AGREEMENT 
 FOR PRECLINICAL AND CLINICAL SERVICES 
 THIS MASTER CONTRACT SERVICES AGREEMENT
(together with any Work Orders, the “Agreement”) is made as of January 2, 2012 (the “Effective Date”) by and between Portola Pharmaceuticals, Inc., a Delaware corporation with a principal place of
business at 270 East Grand Avenue, Suite 22, South San Francisco, CA 94080 (Tel: 650-246-7300) (“Portola”) and PPD Development, LP, a Texas Limited Partnership, with a principal office at 929 North Front Street, Wilmington, NC 28401
(Tel: 949-293-1016) (“Service Provider”). 
 1. Background and Agreement Structure. From time to time, Portola may want
Service Provider to provide certain preclinical and clinical research services (the “Services”). Service Provider provides preclinical analytical services and clinical research services for the development of pharmaceutical
products, and acts as a contract research organization to administer human clinical trials and perform pharmacokinetic data management and statistical services in connection with those trials. Portola is sponsoring human clinical trials (each, a
“Study”) of its proprietary compound(s) (each, a “Study Drug”) in accordance with clinical research protocol(s) (each, a “Protocol”). This Agreement contains general terms and conditions
under which Portola would engage Service Provider and under which Service Provider would provide Services. Portola and Service Provider must complete and execute a work order, project order or statement of work, (each, a “Work
Order”) before any Services are provided. For non-clinical services, each Work Order will include, at a minimum, the information relating to the specific Services outlined in the sample Work Order attached as Appendix A. For clinical
services, each Work Order will include, at a minimum, the information relating to the specific Services outlined in the sample Work Order attached as Appendix B. However, neither Portola nor Service Provider is obligated to execute any Work Order.
Once executed, a Work Order becomes part of this Agreement, although the terms in a Work Order will govern only Services described in that Work Order. A Work Order may not change any term in this Agreement unless the Work Order clearly and
specifically states that it is modifying the Agreement and provides reference to the term of this Agreement that is being modified, however, terms may be modified within a Work Order which will be in effect for that specific Work Order and that Work
Order only. 
  

	2.	Services. 

  

	 	2.1	Provision of Services. Service Provider agrees to provide all Services identified in any Work Order: (a) promptly, (b) at such times and at such
places as described in the applicable Work Order, (c) within the time period specified in the applicable Work Order, and (d) in accordance with the highest prevailing industry standards and practices for the performance of similar
services. For each Work Order, Service Provider will designate a “Project Leader” who will be available for frequent communications with Portola regarding the Services provided under that Work Order. For each Work Order, Portola will
designate a “Representative” who will be the point of contact for the Project Leader. 

  

	 	2.2	 Audits. Provided Portola provides reasonable advance notice to Service Provider [*], with [*], Service Provider will allow, at normal business
hours and at mutually agreeable times (a) Portola employees and representatives (representatives may include entities with whom Portola has license 










	 	
agreements or marketing and / or development collaborations to which the Services are related), provided that said representatives who in Service Provider’s discretion, not to be
unreasonably withheld, are not competitors of Service Provider (a competitor meaning an entity that is in the primary business of providing services for which Portola has engaged Service Provider), and (b) representatives of regulatory
agencies, to review Service Provider’s standard operating procedures and records, including financial records, pertaining to the Services and to inspect the facilities used to render the Services under the applicable Work Order. In addition,
the Project Leader and Representative and their designees will participate in meetings to review performance of the Services and to coordinate such Services as necessary. The Representative, or the Representative’s designee, will have access at
reasonable times to observe the Services in progress or review any and all records generated as a result of Service Provider’s performance of the Services. Any Representative designee who is not an employee of Portola shall execute a
confidentiality agreement with Service Provider prior to any such inspection/audit/review. 

  

	 	2.3	Standard Operating Procedures. Service Provider will, upon request, supply copies to Portola of all standard operating procedures of Service Provider relevant to
the Services rendered under a Work Order. 

  

	 	2.4	Regulatory Contacts. Unless otherwise required by applicable law, Portola will be solely responsible for all contacts and communications with any regulatory
authorities with respect to matters relating to any of the Services. Service Provider will notify Portola promptly, and in no event later than one (1) day, after Service Provider receives any contact or communication from any regulatory
authority directly relating in any way to the Services and will provide Portola with copies of any such communication within one (1) day of receipt of such communication by Service Provider. Service Provider will consult with Portola regarding
the response to any inquiry or observation from any regulatory authority relating in any way to the Services and will allow Portola to participate in any further contacts or communications relating to the Services. Service Provider will comply with
all reasonable requests and take into consideration all comments by Portola with respect to all contacts and communications with any regulatory authority relating in any way to the Services. 


 

	 	2.5	Subcontracting. Service Provider may subcontract the performance of certain portions of the Services, with Portola’s prior written consent, which consent
will not be unreasonably withheld, to an Affiliate (defined below) of Service Provider or to a qualified third party; provided, that (a) Service Provider notifies Portola in writing of the Affiliate or proposed subcontractor and identifies the
specific Services to be performed by such Affiliate or subcontractor, (b) such Affiliate or subcontractor performs those Services in a manner consistent with the terms, conditions and obligations of this Agreement, and (c) Service Provider
remains liable for the performance of such Affiliate or subcontractor. Notwithstanding the foregoing, Service Provider will not be liable for the performance of any subcontractor that is required to be used by Portola or any couriers, labeling,
shipping and manufacturing entities. “Affiliate” means, with respect to each party to this Agreement, any corporation, company, partnership, joint venture and/or firm which controls, is controlled by or is under common control with
that party. As used in this Section 2.5, “control” means (i) in the case of corporate entities, direct or indirect ownership of at least fifty percent (50%) of the stock or shares having the right to vote for the election of
directors (or such lesser percentage that is the maximum allowed to be owned by a foreign corporation in a particular jurisdiction), and (ii) in the case of non-corporate entities, the direct or indirect power to manage, direct or cause the
direction of the management and policies of the non-corporate entity or the power to elect at least fifty percent (50%) of the members of the governing body of such non-corporate entity. 


 

	 	2.6	Change Orders. If the scope of work under a Work Order changes, then the applicable Work Order may be amended as provided in this Section 2.6. If a required
modification to a Work Order is identified by Portola or by Service Provider, the identifying party will notify the other party in writing as soon as reasonably possible. Within fifteen (15) business days of receiving or sending such notice,


  
 [*] = Certain confidential information contained
in this document, marked by brackets, is filed with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended.

Service Provider will provide Portola with a change order containing a description of the required modifications and their effect on the scope, fees and timelines specified in the Work Order,
which change order must be substantially in the form of the sample change order attached hereto as Appendix C (each, a “Change Order”). No Change Order will be effective unless and until it has been signed by an authorized
representative of each party. If Portola does not approve such Change Order, then the parties will use reasonable efforts to agree on a Change Order that is mutually acceptable. If practicable, Service Provider will continue to provide Services
under the existing Work Order during any such negotiations, provided such efforts would facilitate the completion of the work envisioned in the proposed Change Order, but will not commence work in accordance with the Change Order until it is
authorized in writing by Portola. Nothing in this Section 2.6 will limit Portola’s right to terminate the affected Work Order or this Agreement under Section 8. For any Change Order that affects the scope of the regulatory obligations
that have been transferred to Service Provider, Service Provider and Portola will execute a corresponding amendment to the Transfer of Obligations Form. Portola will file such amendment where appropriate, or as required by applicable law or
regulation. 

  

	 	2.7	Portola Cooperation. Portola will cooperate with Service Provider in providing information to Service Provider, taking action and executing documents, as
appropriate, to achieve the objectives of this Agreement. Portola acknowledges and agrees that Service Provider’s performance under this Agreement is dependent on Portola’s timely and effective cooperation with Service Provider.
Accordingly, Portola acknowledges that any delay by Portola may result in Service Provider being released from an obligation or schedule deadline or in Portola having to pay extra fees in order for Service Provider to meet a specific obligation or
deadline despite the delay. Portola shall comply with all applicable laws, rules and regulations governing the performance of its obligations hereunder and the subject matter of this Agreement, including without limitation, the Deliverables (as
defined below). 

  

	 	2.8	Data Verification and Reports. Unless otherwise provided in the applicable Work Order, a copy of all raw data, databases and analytical reports of the data
resulting from the Services will be provided to Portola in a format mutually agreed upon by Portola and Service Provider, compatible with relevant existing databases of Portola and consistent with the Work Order. Service Provider will verify the
accuracy of the data contained in all databases and/or reports provided by it against the raw data and will attach a signed statement attesting to such verification to each database and/or report provided to Portola. 


 

	 	2.9	Transfer or Delegation of Obligations. Service Provider will be responsible for the obligations of a sponsor of a clinical study transferred or delegated by
Portola to Service Provider in Service Provider’s role as the designated contract research organization and as described in a document titled “The Transfer of Obligations of Client Under 21 CFR Subpart D,” (or other applicable
document) which will be included in a Work Order where appropriate. Any transfer of obligations will be construed as a transfer of those obligations described therein in accordance with 21 United States Code of Federal Regulations §312.52 or
other applicable regulation. 

  

	 	2.10	Key Service Provider Personnel. For Services which involve administration and/or monitoring of a Study on behalf of Portola, Service Provider guarantees that the
key Service Provider Personnel (the “Key Service Provider Personnel”) identified and mutually agreed upon in a particular Work Order will remain assigned to the Study covered by such Work Order as long as the individuals remain
employed by Service Provider, unless (a) an individual identified as Key Service Provider Personnel is unavailable for reasons of disability, death, maternity or paternity leave, leave of absence, demotion, illness, promotion or other reasons
not reasonably within Service Provider’s control, or (b) Portola requests, or has requested in connection with an earlier Study, the replacement of any such Key Service Provider Personnel who are not performing to Portola’s
standards. Service Provider will work with Portola in periodically reviewing the performance of the Key Service Provider Personnel and will seek to remedy any underperformance. Service Provider will work with Portola to promptly select a
replacement should any Key Service Provider Personnel resign or become otherwise unavailable as 

  
 [*] = Certain confidential information contained in this document, marked by brackets, is filed with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as
amended. 

  
 Page 3 of 22










	 	
specified above or should Portola request the replacement of such Key Service Provider Personnel, and Portola will have the right to approve the replacement, which approval will not be
unreasonably withheld. If a change of a Key Service Provider Personnel becomes necessary due to a Key Service Provider Personnel’s unavailability or his or her inability to perform or meet commercially reasonable standards of performance, the
replacement personnel will be adequately trained by Service Provider on the applicable protocol, at Service Provider’s expense, in advance of the replacement, and Service Provider will bear all reasonable costs, including without limitation
costs due to delays caused by the replacement. If a change of a Key Service Provider Personnel is requested by Portola and is not for any of the reasons described in the previous sentence, Portola shall be responsible for Service Provider’s
reasonable costs for training replacement personnel on the applicable Protocol and the parties will mutually agree on a timeline for such replacement. Service Provider shall not be responsible for any delays in meeting Study timelines to the extent
such delays are solely the result of a change in Key Service Provider Personnel requested by Portola in accordance with the foregoing sentence. 

  

	 	2.11	Personnel Retention. If, after Service Provider is authorized to commence Services under a Work Order, such Services are delayed at the request of Portola for
more than [*] and such request for delay is based solely on or results solely from causes which are beyond the control of Service Provider, Service Provider will use commercially reasonable efforts to re-allocate the personnel resources assigned to
the Services during the delay to minimize Portola’s costs of delay. If, however, Portola desires for Service Provider to keep Key Service Provider Personnel assigned to such Services during such delay period, Portola agrees that for the
duration of the delay Portola will pay a fee calculated on an FTE-day basis for each such Key Service Provider Personnel it wishes to remain assigned to the Services. Said personnel fees shall be invoiced by Service Provider on a monthly basis, and
shall be due and payable by Portola within [*] of its receipt of invoice. 

  

	 	2.12	Serious Adverse Event and Medical Management Plan. Notwithstanding anything to the contrary herein, in the event Service Provider and Portola agree upon a
serious adverse event and medical management plan relating to a specific Study (“SMMP”), the parties shall comply with the terms and conditions of any such SMMP. In the event of any conflict between the terms and conditions of the SMMP and
the relevant Work Order, the terms and conditions of the SMMP shall control. Sponsor shall be responsible for any additional costs associated with compliance with the SMMP. 


 

	 	2.13	MedDRA and WHODrug Dictonary License. The parties acknowledge that MedDRA and Uppsala Monitoring Centre product licenses are required by all parties who wish to
distribute or receive MedDRA or WHODrug dictionary terminology. Each party represents and warrants that it possesses a current MedDRA and/or Uppsala Monitoring Centre product license. In the event Portola requests that Service Provider
perform services which require Service Provider to distribute MedDRA terminology or WHODrug dictionary to third parties, Portola shall be responsible for ensuring that all such third parties possess the necessary MedDRA and/or Uppsala Monitoring
Centre product licenses. 

  

	 	2.14	Patient Enrollment. Enrollment numbers are good faith estimates and Service Provider shall exercise all reasonable diligence to meet such enrollment estimates.


  

	 	2.15	Final Protocol. Unless otherwise agreed to in writing by both parties, the parties agree that Portola shall be solely responsible for the final review, approval
and adoption of the Protocol and Service Provider shall not be liable for such Protocol. For clarity, Service Provider shall make commercially reasonable efforts to notify Portola of any errors or inaccuracies of which it becomes aware.

Act (HITECH), P.L. No. 111-005, Part I, Title XIII, Subpart D, 13401-13409, and state privacy laws) (collectively referred to as the “Applicable Data Privacy Laws”). 


 

	 	7.2	Compliance. Each party warrants to the other that it will Process the Personal Data in compliance with all Applicable Data Privacy Laws.


  

	 	7.3	Data Processing. Portola and Service Provider acknowledge that Portola is the Data Controller and Service Provider is the Data Processor with respect to the
Processing of Personal Data relating to the Services provided under this Agreement. In the event that the Services are performed by any Service Provider Affiliate then such Service Provider Affiliate shall be a sub-Processor. Service Provider shall
Process the Personal Data only in accordance with instructions from Portola or as may be required or permitted by law. (The instructions may be specific instructions or instructions of a general nature as set out in this Agreement, a Project
Addendum, Protocol, SOP or SMMP or as otherwise notified by Portola to Service Provider during the Term). 

  

	 	7.4	Representative. If Portola wishes to appoint Service Provider as representative to comply with Applicable Data Privacy Law in any EU Member State pursuant to
Article 4 of Directive 95/46/EC and Service Provider is willing to provide such services to Portola, Portola and Service Provider shall enter into a mutually acceptable agreement for such representative purposes. Unless and until such an agreement
is entered into, Service Provider shall not be deemed to be a representative under any Applicable Data Privacy Law. 

  

	 	7.5	Security. Service Provider shall implement appropriate technical and organisational measures to protect the Personal Data as required by ICH-GCP and Applicable
Data Privacy Laws.

authority or other regulatory authority, and provide Portola with cooperation and assistance in relation to any such communication. Service Provider shall be entitled to charge Portola for such
assistance, at its usual hourly rate, unless the communication relates to a breach or violation by Service Provider or a Service Provider Affiliate of its obligations under this Section 7. However, Service Provider and Portola recognize that
any fees charged to the requesting party must comply with Applicable Data Privacy Laws. 

  

	 	7.7	Security Breaches. If Service Provider becomes aware of any breach of an Applicable Data Privacy Law relating to the Services, then it shall promptly notify
Portola and, if requested, assist Portola in meeting any obligations under Applicable Data Privacy Law to notify Data Subjects, regulatory authorities or other required parties. Service Provider shall be entitled to charge Portola for such
assistance, at its usual hourly rate, unless Service Provider or a Service Provider Affiliate was solely responsible for such breach. 

  

	 	7.8	Data Transfers. Service Provider shall only Process or otherwise transfer Personal Data outside the European Economic Area (member states of the European Union
plus, Norway, Iceland & Liechtenstein) as set out in this Agreement, any Work Order, Protocol, SOP or SMMP or with the prior consent of Portola. 

  

	8.	Indemnification, Insurance and Liability. 

  

	 	8.1	Indemnification by Service Provider. Service Provider agrees to indemnify Portola and its directors, officers, and employees (collectively, the “Portola
Indemnitees”) from and against any and all liability, loss, damage, cost, and expense, including reasonable attorneys’ fees and costs (collectively, “Losses”) they may suffer in connection with any claim or lawsuit
brought by a third party arising from a Service Provider Indemnitee’s (defined below) or Service Provider’s approved subcontractors’ (a) negligence or willful misconduct, or (b) material breach of this Agreement.
Notwithstanding the foregoing, Service Provider’s obligation to indemnify the Portola Indemnitees will be proportionally reduced to the extent that such Losses fall within Portola’s indemnification obligations under Section 8.2 below.


  

	 	8.2	Indemnification by Portola. Portola agrees to indemnify Service Provider and its directors, officers, and employees (collectively, the “Service Provider
Indemnitees”) from and against any and all Losses they may suffer in connection with any claim or lawsuit brought by a third party arising from (a) personal injury, or death of a Study subject caused by (i) any Study Drug or other
materials supplied by Portola or anyone acting on Portola’s behalf that is dispensed in strict accordance with the relevant Protocol and Portola’s written instructions, (ii) any non-standard of care procedure required by the Protocol,
(b) any deviations from the applicable Protocol necessary to preserve the health, safety and welfare of the Study subjects that meets all applicable standards of care, (c) any claims for patent infringement related to a Study Drug,
compound or other materials supplied by Portola, or anyone acting on Portola’s behalf, to Service Provider in connection with a Study, provided Service Provider Indemnitee has acted in strict compliance with the relevant Protocol and
Portola’s instructions, (d) after regulatory approval of a Study Drug that was the subject of the Services, personal injury or death caused by such Study Drug, or (e) a Portola Indemnitees’ use of the Deliverables, negligence,
willful misconduct, or material breach of this Agreement. Notwithstanding the foregoing, Portola’s obligation to indemnify the Service Provider Indemnitees will be proportionally reduced to the extent that such Losses fall within Service
Provider’s indemnification obligations under Section 8.1 above. 

  

	 	8.3	Indemnification Procedures. Each party agrees to notify the other party within fifteen (15) days of receipt of any claims made for which the other party
might be liable under Section 8.1 or 8.2, as the case may be. The indemnifying party will have the right, but not the obligation, to defend, negotiate, and settle such claims. The indemnified party will be entitled to participate in the

defense of such matter and to employ counsel at its expense to assist therein; provided, however, that if the indemnifying party elects to defend the indemnified party, the indemnifying
party will have final decision-making authority regarding all aspects of the defense of any claim. The party seeking indemnification will provide the indemnifying party with such information and assistance as the indemnifying party may reasonably
request, at the expense of the indemnifying party. Neither party will be responsible or bound by any settlement of any claim or suit made without its prior written consent; provided, however, that the indemnified party will not
unreasonably withhold or delay such consent. If a settlement contains an absolute waiver of liability for the indemnified party, and each party has acted in compliance with the requirements of this Section 8.3, then the indemnified party’s
consent will be deemed given. Notwithstanding the foregoing, neither party will agree to settle any claim on such terms or conditions as would impair the other party’s ability or right to research, develop, manufacture, market, sell or
otherwise use the Study Drug, or as would impair a party’s ability, right or obligation to perform its obligations under this Agreement. 

  

	 	8.4	Insurance. Portola and Service Provider will each undertake to purchase and maintain insurance of such types and amounts reasonably adequate to cover any
liabilities arising out of its obligations hereunder. Portola further undertakes to purchase and maintain insurance of such types and amounts reasonably adequate (including but not limited to that required by law) to cover any
liabilities arising in relation to all clinical trials contracted to Service Provider pursuant to this Agreement. 

 Portola and Service Provider will each undertake, upon request by the other party, to provide the other party a certificate (or certificates) of insurance setting forth the liability limits,
exclusions and deductibles of the insurance such party is required to carry pursuant to this Agreement. 
  

	 	8.5	Liability. 

  

	 	(a)	For Failure to Perform. In the event that the Services provided hereunder (or any portion thereof) do not meet the specifications or other performance criteria
agreed to by Service Provider and Portola in a Work Order, then Service Provider will, at Portola’s first option, promptly (i) re-perform such Services at Service Provider’s cost, or (ii) refund to Portola all amounts paid by
Portola to Service Provider in connection with such Services. 

  

	 	(b)	Limitation. NEITHER PARTY WILL BE LIABLE UNDER ANY LEGAL THEORY (WHETHER TORT, CONTRACT OR OTHERWISE) FOR SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR
PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, INCLUDING LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, HOWEVER CAUSED, EVEN IF THE PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES, EXCEPT AS A RESULT OF A BREACH OF THE CONFIDENTIALITY AND NON-USE OBLIGATIONS IN SECTION 6. NOTHING IN THIS SECTION 8.5 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY. TO
THE FULLEST EXTENT PERMITTED BY LAW, AND NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT OR ANY WORK ORDER, THE TOTAL LIABILITY, IN THE AGGREGATE, OF [*] AND ITS AGENTS, AND ANY OF THEM, TO [*] AND ANYONE CLAIMING BY OR THROUGH [*], FOR ANY
AND ALL CLAIMS, LOSSES, COSTS OR DAMAGES, INCLUDING WITHOUT LIMITATION, ATTORNEYS’ FEES AND COSTS AND EXPERT-WITNESS FEES AND COSTS OF ANY NATURE WHATSOEVER OR CLAIMS EXPENSES RESULTING FROM OR IN ANY WAY RELATED TO THIS AGREEMENT OR ANY WORK
ORDER FROM ANY CAUSE OR CAUSES SHALL NOT EXCEED [*] OR [*] THE [*] OR [*], WHICH IS OR ARE [*]. IT IS INTENDED THAT THIS LIMITATION APPLY TO ANY AND ALL LIABILITY OR CAUSE OF ACTION HOWEVER ALLEGED OR ARISING EXCEPT FOR THE PARTIES’ INDEMNITY
OBLIGATIONS UNDER SECTIONS 8.1 AND 8.2.

	 	8.6	Each party agrees that its obligations hereunder are necessary and reasonable in order to protect the other party and the other party’s business, and
expressly agrees that monetary damages would be inadequate to compensate the other party for any breach of the terms of this Agreement. Accordingly, each party agrees and acknowledges that any such violation or threatened violation may cause
irreparable injury to the other party, and that, in addition to any other remedies that may be available, in law, in equity or otherwise, the other party shall be entitled to obtain injunctive relief against the threatened breach of this Agreement
or a Work Order or the continuation of any such breach, without the necessity of proving actual damages. 

  

	9.	Expiration and Termination. 

  

	 	9.1	Expiration. This Agreement will expire on the later of (a) three (3) years from the Effective Date or (b) the completion of all Services under the

	 	9.4	Insolvency. Either party hereto may terminate this Agreement immediately upon the occurrence of an “Insolvency Event” with respect to the other party.
For purposes of this Agreement, “Insolvency Event” shall mean (1) a party or any of its subsidiaries commences a voluntary proceeding seeking liquidation, reorganization or other relief with respect to itself or its
debts under any bankruptcy, insolvency or other similar law or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, or consents to any such relief or to the

	 	(f)	The terms, conditions and obligations under Sections 2.2, 2.4, 4, 5, 6, 8, 9.5, 10.2, 10.3, 10.4, 10.7, 10.8, 10.9, and 10.15 will survive any such termination or
expiration. 

  

	10.	Miscellaneous. 

  

	 	10.1	Independent Contractor. All Services will be rendered by Service Provider as an independent contractor and this Agreement does not create an employment
relationship, partnership or joint venture between Portola and Service Provider. Neither party will in any way represent itself to be a partner or joint venturer of or with the other party. 


 

	 	10.2	Use of Names. Neither party has the right to use the other party’s name, symbol, trade name or the names of the other party’s employees in any

	 	10.5	Entire Agreement. This Agreement constitutes the entire agreement of the parties with regard to its subject matter, and supersedes all previous written or oral
representations, agreements and understandings between Portola and Service Provider with regard to such subject matter, including without limitation a Mutual Confidentiality Agreement dated April 30, 2010 and a Letter of Intent dated
January 13, 2012 (the “LOI”). Upon execution of this Agreement, Services (as defined in the LOI) performed under the LOI shall be subject to the terms of this Agreement. In the event of any conflict, discrepancy, or inconsistency
between the terms set forth in the body of this Agreement, any Work Order or any purchase order issued under this Agreement, the terms of the body of this Agreement will control unless specifically stated otherwise in a Work Order. Further, the
terms of a Work Order will control over the terms of any purchase order issued by Portola for the Services under that Work Order. 

  

	 	10.6	No Modification. This Agreement may be changed only by a writing signed by an authorized representative of each party. 


 

	 	10.7	Severability; Reformation. Any of the provisions of this Agreement which are determined to be invalid or unenforceable in any jurisdiction will be
ineffective to the extent of such invalidity or unenforceability in such jurisdiction, without rendering invalid or unenforceable the remaining provisions hereof and without affecting the validity or enforceability of any of the other terms of this
Agreement in such jurisdiction, or the terms of this Agreement in any other jurisdiction. The parties will substitute for the invalid or unenforceable provision a valid and enforceable provision that conforms as nearly as possible with the original
intent of the parties. 

  

	 	10.8	Governing Law. This Agreement will be construed and interpreted and its performance governed by the laws of the State of New York, without regard to any choice
of law principle that would dictate the application of the law of another jurisdiction. The parties expressly reject any application to this Agreement of (a) the United Nations Convention on Contracts for the International Sale of Goods, and
(b) the 1974 Convention on the Limitation Period in the International Sale of Goods, as amended by that certain Protocol adopted in Vienna on April 11, 1980. 


 

	 	10.9	Waiver. No waiver of any term, provision or condition of this Agreement in any one or more instances will be deemed to be or construed as a further or continuing
waiver of any other term, provision or condition of this Agreement. Any such waiver must be evidenced by an instrument in writing executed by an officer authorized to execute waivers. 


 

	 	10.10	Counterparts. This Agreement may be executed in any number of counterparts, each of which will be deemed an original and all of which together will constitute
one and the same instrument. A facsimile or scanned copy of this Agreement that includes a party’s signature will be deemed an original. 

  

	 	10.11	Headings. This Agreement contains headings only for convenience and such headings should not be used in the construction of this Agreement.


  

	 	10.12	Force Majeure. If either party shall be delayed, hindered, or prevented from the performance of any act required hereunder by reason of strike, lockouts, labor
troubles, restrictive governmental or judicial orders or decrees, riots, insurrection, war, acts of God, inclement weather, or other cause beyond such party’s reasonable control (each, a “Disability”), then performance
of such act shall be excused for the length of time necessary to cure such Disability and resume performance. A party shall not be liable for any delays resulting from a Disability, and any affected timelines shall be extended for a period at least
equal to that of the Disability. The party incurring the Disability shall provide notice to the other of the commencement and termination of the Disability.

	 	10.13	Construction. Except where the context otherwise requires, wherever used the singular shall include the plural, the plural the singular, the use of any gender
shall be applicable to all genders and the word “or” is used in the inclusive sense. The captions of this Agreement are for convenience of reference only and in no way define, describe, extend or limit the scope or intent of this Agreement
or the intent of any provision contained in this Agreement. The language of this Agreement shall be deemed to be the language mutually chosen by the parties and no rule of strict construction shall be applied against either party hereto.

or other Service Provider representative on Line 15 of Form FDA 1571 or as the Senior Medical Officer in Canada on Line 87 of Form HC/SC 3011 or in any similar capacity for clinical trials conducted in other countries without Service Provider’s
written consent. Portola acknowledges and understands that if Portola desires Service Provider to be responsible for review and evaluation of information relevant to the safety of the drug, Portola will have to enter into a separate contract with
Service Provider for the provision of these services. 

  

	 	10.15	Covenant Not to Interfere. Neither party will hire for employment any employee of the other party involved in providing or receiving Services under a Work Order
while the employee is still employed by the other party during the active term of the Work Order. 

 IN WITNESS
WHEREOF, the parties have caused this Agreement to be executed by their duly authorized representatives as of the Effective Date.

 APPENDIX D 

 

	1.	Currency Management. 

  

	 	a)	Direct Fees: All Direct Fees owed to CRO for Services performed under this Agreement or any Schedule shall generally be invoiced to and paid by Portola in $ USD
for Services performed in the North America (NA), Latin America (LA) and Asia-Pacific (APAC) regions and invoiced to and paid by Portola in € Euros for Services performed in Europe, the Middle East and Africa (EMEA); the “Regional Contract
Currency/Currencies”. 

 Should Portola wish to be invoiced in $ USD for Services performed in EMEA, CRO shall
specify in the proposal and the contract the estimated exchange rate (“Exchange Rate”) used to prepare the budget or payment schedule for such Project Addendum. This Exchange Rate will be the one used for the preparation of
each invoice for Services and payment by Portola. The “Spot Rate” for purposes of reconciliation, shall mean the actual spot rate in the Wall Street Journal at the close of the day before the date on which the invoice is raised. At the
conclusion of each calendar year, a reconciliation shall be undertaken. 
 If requested by Portola, CRO shall compare the USD
total of the invoices billed to Portola that year at the Exchange Rate with the USD total of those same invoices when converted using the Spot Rate. In the event the comparison demonstrates that the difference in such amounts is [*] or more or is
greater than USD $[*] such difference shall be [*] with the difference invoiced or credited, as the case may be, to Portola (an example of which follows below). The reconciliation invoice or credit note will be issued by CRO in $ USD. The process of
reconciliation is not cumulative but shall be conducted on a calendar year basis and completed by the end of March in the subsequent year. 
 Shared Reconciliation Examples: 
  

	 	•	 	 FX Variance is $[*] representing [*] of the total FX component of the annual invoicing: 



 

	 	•	 	 An adjustment (cash) is made between Portola and CRO for $[*] being the excess of the variance over $[*] ($[*] for $[*])



  

	 	•	 	 FX Variance is $[*] representing [*] of the total FX component of the annual invoicing: 



 

	 	•	 	 An adjustment (cash) is made between Portola and CRO for $[*] being the excess of the variance over [*] ($[*] for $[*])



  

	 	•	 	 FX Variance is $[*] representing [*] of the total FX component of the annual invoicing: 



 

	 	•	 	 No adjustment is required 


  

	 	b)	Pass Through Costs: Where CRO incurs Pass Through Costs in a currency other than $ USD in NA, LA or APAC and other than € Euros in EMEA, the Regional
Contract Currency/Currencies, CRO shall, for Portola invoicing and payment purposes, convert such costs to the applicable Regional Contract Currency based on an average exchange rate between the local currency and the regional Contract Currency for
the month in which such costs were incurred. 

  

	 	c)	Investigator Fees: CRO shall pay investigator fees in the currency specified in the investigator agreements. For Portola invoicing and payment purposes, CRO
shall convert all investigator fees that are to be paid in a currency other than the Regional Contract Currency to the Regional Contract Currency. The conversion to the Regional Contract Currency shall be based on an average exchange rate between
the currency specified in an investigator agreement and the Regional Contract Currency

for the month prior to the month the Portola invoice is raised. All amounts invoiced to Portola will be based upon an accrual of costs owed to investigators. At the end of the project a
reconciliation will be completed between the estimated exchange rate used for the purposes of billing on the basis of the accrued costs versus the exchange rate when the actual payment is made to the sites, and any variation will be billed or
credited to Portola as applicable.

 THIS AMENDMENT NO. 1 (the “Amendment”) to the Master Contract Services Agreement (defined below) is made effective as of
March 5, 2012 by and between Portola Pharmaceuticals, Inc., (“Portola”) and PPD Development, LLC, (formerly PPD Development, LP, “Service Provider”) and upon execution will be incorporated into the Master Contract Services
Agreement for Preclinical and Clinical Services between Portola and Service Provider dated January 2, 2012 (the “Master Contract Services Agreement”). All capitalized terms not defined in this Amendment shall have the same meaning as
in the Master Contract Services Agreement. 
 WHEREAS, a Master Contract Services Agreement, effective January 2,
2012, was entered into by and between Portola and Service Provider; and 
 WHEREAS, the parties now wish to amend
Section 8.2 of the Master Contract Services Agreement. 
 NOW, THEREFORE, in consideration of the premises contained
herein and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows: 
  

	 	1.	Indemnification by Portola. Section 8.2 of the Master Contract Services Agreement is hereby deleted in its entirety and replaced with the following:


 Portola agrees to indemnify Service Provider and its directors, officers, and employees and Service
Provider’s Affiliates authorized by Portola under a Power of Attorney, or similar instrument, to perform Services on behalf of Portola (collectively, the “Service Provider Indemnitees”) from and against any and all Losses they
may suffer in connection with any claim or lawsuit brought by a third party arising from (a) personal injury, or death of a Study subject caused by (i) any Study Drug or other materials supplied by Portola or anyone acting on
Portola’s behalf that is dispensed in strict accordance with the relevant Protocol and Portola’s written instructions, (ii) any non-standard of care procedure required by the Protocol, (b) any deviations from the applicable
Protocol necessary to preserve the health, safety and welfare of the Study subjects that meets all applicable standards of care, (c) any claims for patent infringement related to a Study Drug, compound or other materials supplied by Portola, or
anyone acting on Portola’s behalf, to Service Provider in connection with a Study, provided Service Provider Indemnitee has acted in strict compliance with the relevant Protocol and Portola’s instructions, (d) after regulatory
approval of a Study Drug that was the subject of the Services, personal injury or death caused by such Study Drug, or (e) a Portola Indemnitees’ use of the Deliverables, negligence, willful misconduct, or material breach of this Agreement.
Notwithstanding the foregoing, Portola’s obligation to indemnify the Service Provider Indemnitees will be proportionally reduced to the extent that such Losses fall within Service Provider’s indemnification obligations under
Section 8.1 above.
