Payments under this Agreement:



(a) Payments and
Reports. Genentech shall make Royalty Payments to Curis or its designee quarterly within ninety (90) days following the end of each calendar quarter in which Royalty Payments are due. Each Royalty Payment shall be accompanied by a written
report, setting forth all the information necessary for the calculation of such payment. Unless otherwise requested, or consented to in writing, by Curis, all Royalty Payments and reports related to Net Sales by Genentechs Sublicensees shall
be made to Curis by Genentech together with (or as a part of) Genentechs payments and reports.



(b) Records. Genentech shall keep full, true and accurate books of account containing all particulars that may be necessary for the purpose of
showing Net Sales and demonstrating the calculation of Royalty Payments. Such books of account and the supporting data and other records shall be kept at the principal place of business of Genentech. Genentechs books and records shall be open
at all reasonable times, for two (2) calendar years following the end of the calendar quarter to which they pertain, for examination in accordance with the provisions of Section 7.5(c); provided, however, any given set of books and records may only
be examined once.



(c) Audits. At the request and
expense of Curis, Genentech shall permit a nationally recognized independent certified public accountant, selected by Curis and reasonably acceptable to Genentech, to examine, not more than once in any four (4) consecutive calendar quarters during
the period in which Genentech has an obligation to pay Royalty Payments under this Agreement, such books of account and records under Section 7.5(b) as may be necessary to determine the correctness of any report or payment related to Royalty

uncontested, understated Royalty Payments. Any overpayment of Royalty Payments shall be promptly refunded or fully creditable against amounts payable in subsequent payment periods, at Genentechs election. Genentech shall pay contested,
understated Royalty Payments, if any, that are due promptly after the dispute is resolved, in accordance with the provisions of Article 14. If such accountant reasonably determines that Royalty Payments payable under this Agreement have been, for
any four (4) consecutive calendar quarters in total, understated by more than five percent (5%), and such determination is uncontested by Genentech (or if contested, such determination is found to be correct), Genentech shall pay the reasonable
costs of the examination. The Parties agree that all information subject to review under this Section 7.5(c) is Confidential Information of Genentech and may only be used for purposes germane to this Section 7.5(c), and that Curis shall retain and
cause its accountant to retain all such information in confidence.

Sales of Licensed Products sold in such country shall continue to be accrued without interest in such country, and shall continue to be reported, but such Royalty Payments will not be paid until they may be removed from such country. At such time as
