BELLICUM will keep, and will require its Affiliates and Permitted Sublicensees to keep, complete, true and accurate books of accounts and records for the purpose of determining the existence and accuracy of the payments to be made under this Agreement. Such books and records must be kept for at least […***…] following the end of the calendar quarter to which they pertain. Such records will be open for inspection during such […***…] period by independent accountants selected by AGENSYS and reasonably acceptable to BELLICUM, solely for the purpose of verifying the accuracy of payments and payment-related reports to be made by BELLICUM hereunder. All such accountants will be required to enter into a confidentiality agreement with BELLICUM. The records for any calendar year may be inspected only once by AGENSYS. Except for for-cause audits, such inspections may be made no more than once each calendar year, during normal business hours that are mutually agreed by the Parties, and upon at least […***…] prior written notice. The accountants will disclose to AGENSYS, and AGENSYS will disclose to […***…], only information directly pertaining to the accuracy of payments and payment-related reports to be made by BELLICUM to AGENSYS, and by AGENSYS to […***…], respectively. The inspection report will be copied to BELLICUM. If any errors, that if corrected would favor AGENSYS, are discovered in the course of such inspection, then within […***…] after its receipt of the inspection report, BELLICUM will pay AGENSYS those amounts (plus interest as provided under Section 4.7, in the case of AGENSYS, and interest as provided under Section 22.1 of the […***…] License Agreement, in the case of amounts AGENSYS is obligated to pay to […***…] as a result of such errors) that AGENSYS would have received in the absence of such errors. Inspections conducted under this Section 4.8 will be at the expense of AGENSYS, unless a variation or error, that if corrected would favor AGENSYS exceeding […***…] percent ([…***…]%) of the amount stated for any calendar year covered by the inspection is established in the course of such inspection, whereupon all reasonably incurred fees and expenses for the inspection for such period will be paid promptly by BELLICUM.
