Records and Audits RBNC will keep complete and accurate records of the underlying revenue and expense data relating to the calculations of Net Sales generated in the then current Calendar Year and payments required under this Agreement, and during the preceding [***] Calendar Years. AMGEN will have the right, [***] at its own expense, to have a nationally recognized, independent, certified public accounting firm, selected by it and subject to RBNC’s prior written consent (which shall not be unreasonably withheld), review any such records of RBNC and its Affiliates and Sublicensees (the “Audited Party”) in the location(s) where such records are maintained by the Audited Party upon reasonable written notice (which shall be no less than [***] days’ prior written notice) and during regular business hours and under obligations of strict confidence, for the sole purpose of verifying the basis and accuracy of payments made under Section 3.2 (Royalties) within the [***] month period preceding the date of the request for review. No Calendar Year will be subject to audit under this Section 3.9 more than once. RBNC will receive a copy of each such report concurrently with receipt by AMGEN. Should such inspection lead to the discovery of a discrepancy to AMGEN’s detriment, RBNC will, within [***] days after receipt of such report from the accounting firm, pay any undisputed amount of the discrepancy together with interest at the rate set forth in Section 3.8 (Late Payments). AMGEN will pay the full cost of the review unless the underpayment of amounts due to AMGEN is [***] of the amount due for the entire period being examined, in which case RBNC will pay the cost charged by such accounting firm for such review. Should the audit lead to the discovery of a discrepancy to RBNC’s detriment, RBNC may credit the amount of the discrepancy, without interest, against future payments payable to AMGEN under this Agreement, and if there are no such payments payable, then AMGEN shall pay to RBNC the amount of the discrepancy, without interest, within [***] days of AMGEN’s receipt of the report.
Inspection of Records Upon reasonable notice to the Administrative Trustees and the Property Trustee, the records of the Trust shall be open to inspection by Securityholders during normal business hours for any purpose reasonably related to such Securityholder's interest as a Securityholder.
