 The deductions set forth in clauses (i) through (v) above will be determined in
accordance with GAAP, as consistently applied by Virobay across all of its products. 
 (b) A “sale” will include the
transfer or other disposition of an Assigned Product for consideration other than cash, in which case such consideration will be valued at the fair market value thereof. In the event that an Assigned Product is sold either for consideration other
than cash or as part of a bundled product, the Net Sales of such Assigned Product will be the greater of (i) the recognized amount attributable to the Assigned Product, or (ii) the average unit price of such Assigned Product in Dosage Form
when sold (other than as part of a bundle) in cash transactions in such country. If Virobay, its Affiliates or Licensees do not separately sell such Assigned Product in such country, the Net Sales for such Assigned Product will be calculated based
on the average unit price of such Assigned Product when sold (other than as part of a bundle) in cash transactions in Major Market Countries collectively. 

(c) Amounts received by Virobay, its Affiliates or Licensees for the sale of Assigned Products among Virobay, its Affiliates and
Licensees for resale will not be included in the computation of Net Sales hereunder. Distributors of Virobay selling Assigned Products will not be deemed to be Licensees of Virobay. 

(d) If Virobay, its Affiliates or Licensees sell an Assigned Product in Bulk Form to a Third Party who is not a Licensee, for resale
(and in such event such Third Party’s sales would not then constitute “Net Sales” of a Licensee ), then the amount to be included in the calculation of Net Sales arising from such sale by Virobay, its Affiliates or Licensees will be
the amount that would have been recognized as gross revenue (minus the deductions set forth above) if such Assigned Product had been sold in Dosage Form, to be determined using the average units of Assigned Product in Dosage Form expected to be
produced from the quantity of Assigned Product in Bulk Form sold and the average amount of gross revenue recognized by Virobay, its Affiliates or Licensees for the same Assigned Product in Dosage Form sold in the same country during the preceding
three calendar months. If there have been no sales of the same Assigned Product in Dosage Form in the same country during the preceding three calendar months, the Parties will agree upon an amount for such Bulk Form sale which will not be less than
a good faith determination of the amount invoiced by the Third Party upon resale of Assigned Product in Dosage Form obtained from the quantity of Assigned Products purchased in Bulk Form. 

(e) In the event that, on a country by-country basis, an Assigned Product is sold in the form of a Combination Product, the Net Sales
for such Combination Product will be calculated as follows: 
 (i) If Virobay, its Affiliates or Licensees separately sell, in such
country, (x) Assigned Products as contained in such Combination Product and (y) other products containing as their sole active ingredient(s) the other Active Components in such Combination Product, the Net Sales attributable to such
Combination Product will be calculated by multiplying actual Net Sales of the Combination Product (calculated in accordance with Section 1.28(a)-(d))

by the fraction A/(A+B) where: A is Virobay’s (or its Affiliates or Licensees, as applicable) average wholesale price during the period to which the Net Sales calculation applies to its
three (3) largest distributors of the Assigned Product in such country, and B is Virobay’s (or its Affiliate’s or Licensee’s, as applicable) average wholesale price during the period to which the Net Sales calculation applies to
its three (3) largest distributors in such country of products which contain as their sole active ingredient(s) the other Active Components in the Combination Product. 

(ii) If Virobay, its Affiliates or Licensees separately sell, in such country, Assigned Products as contained in such Combination
Product but do not separately sell, in such country, other products containing as their sole active ingredient(s) the other Active Components in such Combination Product, the Net Sales attributable to such Combination Product will be calculated by
multiplying the Net Sales of such Combination Product (calculated in accordance with Section 1 .28(a)-(d)) by the fraction A/C where: A is Virobay’s (or its Affiliate’s or Licensee’s, as applicable) average wholesale price for
the Assigned Product(s) as contained in such Combination Product during the period to which the Net Sales calculation applies to its three (3) largest distributors of an Assigned Product in such country, and C is Virobay’s (or its
Affiliate’s or Licensee’s, as applicable) average wholesale price for the Combination Product during the period to which the Net Sales calculation applies to its three (3) largest distributors of the Combination Product in such
country. 
 (f) If Virobay, its Affiliates or Licensees do not separately sell, in such country, Assigned Products, the Net Sales
attributable to such Combination Product will be calculated by multiplying the Net Sales of such Combination Product (calculated in accordance with Section 1.28(a)-(d)) by the fraction D/D+E where D is the actual total cost of the Assigned
Product(s) at the point of formulation into the Combination Product and E is the actual total cost of the other Active Component(s) in the Combination Product. 

1.30 “New Drug Application” or “NDA” means (a) a FDA new drug application, biologics license
application or its equivalent in the United States, or (b) any corresponding application to a Regulatory Authority in any country. 

1.31 “Patent” means (a) an issued, unexpired patent (with the term “patent” being deemed to encompass,
without limitation, an inventor’s certificate) in any country which has not been held invalid or unenforceable by a court of competent jurisdiction from which no appeal can be taken or has been taken within the required time period, including
without limitation any substitution, extension, registration, confirmation, reissue, re-examination, renewal or any like filing thereof; (b) an application for a patent pending in any country, including without limitation any provisional,
converted provisional, continued prosecution application, continuation, divisional or continuation-in-part thereof; any patents issuing therefrom; and any substitution, extension, registration, confirmation, reissue, reexamination, renewal or like
filing thereof. 
 1.32 “Phase 3 Clinical Trial” means a pivotal human clinical trial in any country the results of
which could be used to establish safety and efficacy of an Assigned Product or a Combination Product as a basis for a regulatory filing or that would otherwise satisfy requirements of 21 C.F.R. §312.21(c) in the United States, or its foreign
equivalent.

 6.5 Royalty Payments and Reports. All Royalties payable to Celera under this Agreement
will be paid in Dollars by wire transfer of immediately available funds into an account designated by Celera within [* * *] days after the end of each calendar quarter, except as otherwise specifically provided herein. Each payment of Royalties
owing to Celera will be accompanied by a statement, certified by an executive officer of Virobay as accurate to the best of its ability consistent with Virobay’s standard practices in performing such computations and in accordance with GAAP, on
a country-by-country basis, setting forth (a) the amount of gross sales of Assigned Products and, if applicable, Combination Products in such quarter, (b) any deductions from such amount of gross sales as permitted pursuant to

with GAAP, the accuracy of calculations of all sums or credits due to Celera under this Agreement. Such records will be retained for no less than a [* * *] year period following the year in which a payment was made hereunder. Once per calendar year,
Celera may engage, at its own expense, an independent certified public accountant appointed by Celera and reasonably acceptable to Virobay, to examine, in confidence, the records of Virobay as may be necessary to determine, with respect to any
calendar year, the correctness or completeness of any report or payment required to be made under this Agreement. The report of such accountant will be limited to a certificate verifying any report made or payment submitted by Virobay during such
period but may include, in the event the accountant is unable to verify the correctness of any such payment, information relating to why such payment is unverifiable. All information contained in any such certificate will be Confidential Information
of Virobay hereunder. If any audit performed under this Section 6.8 discloses an underpayment, Virobay will promptly remit to Celera the underpaid amount, plus interest as provided in Section 6.12 and, if the underpayment is more than [* *

is required by law, rule or regulation to withhold taxes from such types of payments due Celera hereunder, Virobay will (a) deduct those taxes from the remittable amount, (b) pay the taxes to the proper taxing authority, and (c) send
original copies of all official receipts evidencing such tax obligation together with written evidence of payment to Celera within [* * *] business days following such payment. In the event of any such withholding, the Parties agree to confer
regarding other reasonable, lawful measures to minimize such withholding. 
 6.8 Blocked Currency. In any country where conversion of
the local currency is blocked and such currency cannot be removed from the country, Virobay will make payments of any Royalties due hereunder in respect of Net Sales of Assigned Products or Combination Products in such country in local currency by
depositing such amount to an interest-bearing account in the name of Celera, in a bank within such country designated by Celera.

Wall Street Journal (at http://www.interactive.wsj.com) for the calendar quarter in which such sales or other distributions were made. 

6.10 Late Payments. Any amounts not paid by Virobay when due under this Agreement will be subject to interest from and including the

obligations only if the failure by the Virobay Indemnitee to deliver prompt notice is prejudicial to its ability to defend such action. Each Virobay Indemnitee will provide Celera with the exclusive ability to defend such claim (with the reasonable
cooperation of Virobay Indemnitees), subject to Virobay’s right to participate in and have counsel selected by it participate, at Virobay’s expense. Virobay may not settle any claim under this Section 9.1 without Celera’s prior
written consent. Celera’s obligation to Indemnify the Virobay Indemnitees pursuant to this Section 9.1 will not apply to the extent of any Losses (i) that arise from the negligence or intentional misconduct of any Virobay Indemnitee;
or (ii) that arise from Virobay’s material breach of this Agreement; or (iii) for which Virobay is obligated to Indemnify the Celera Indemnitees pursuant to Section 9.2 of this Agreement. 

9.2 Indemnification by Virobay. Virobay hereby agrees to Indemnify Celera, its Affiliates, and their respective agents, directors,

or in the case of a Licensee, will self-insure to cover such obligations. Virobay, its Affiliates, or Licensees (as appropriate) will carry comprehensive general liability, property damage, and product liability insurance with a minimum insurance
limit of [* * *]. Each insurance policy required by, and procured under, this Section 9.3 by Virobay will name Celera as an additional insured. The existence of such insurance will not limit the insuring Party’s liability with respect to

material change in such insurance or self-insurance which materially adversely affects the rights of Celera hereunder.

successors and assigns of the assigning Party, and the name of a Party appearing herein will be deemed to include the name(s) of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Agreement.
Any assignment or attempted assignment by either Party in violation of the terms of this Section 13.6 will be null and void and of no legal effect. Celera may assign its right of payments under this Agreement without the prior approval of
Virobay. 
 13.7 Performance by Affiliates and Licensees. Each of Celera and Virobay acknowledge that obligations under this
Agreement may be performed by Affiliates of Celera and Virobay or Virobay’s Licensees. Wherever in this Agreement the Parties delegate responsibility to Affiliates or Licensees, the Parties agree that such entities may not make decisions
inconsistent with this Agreement, amend the terms of this Agreement or act contrary to its terms in any way. 
 13.8 Counterparts.
This Agreement may be executed in two (2) or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. 

13.9 Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of
competent jurisdiction from which no appeal can be or is taken, the provision will be considered severed from this Agreement and will not serve to invalidate any remaining provisions hereof. The Parties must make a good faith effort to replace any
invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

13.11 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts,
as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. If Celera is offered Control of any Celera Patents or Celera Technology pursuant to the Schering Agreement after the Effective Date, Celera shall so
inform Virobay in writing, and Virobay shall have the right to elect whether or not to obtain all of Celera’s rights in such Patent, Technology or other intellectual property right pursuant to the terms of the Schering Agreement; provided that
such actions will be at Virobay’s sole expense and at no expense to Celera and that Celera will have no liability to any Third Party in connection therewith. If Celera obtains Control of any such Patents or Celera Technology, whether pursuant
to the preceding sentence or otherwise, Celera will transfer such items to Virobay, at Virobay’s expense. Celera will use commercially reasonable efforts to provide all cooperation, assistance and access to data reasonably requested by Virobay

name or logo of the other Party, including the names “Celera”, “Applera”, and “Virobay”, without the prior written consent of the owning Party. 

13.14 No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other
matter will not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time
