All activities undertaken under this Agreement by Labcorp shall comply in all material respects with College of American Pathologists (CAP) rules. Labcorp represents that it has and shall maintain Clinical Laboratory Improvement Act (CLIA) certification. This Agreement shall contain all the conditions under which Labcorp will provide clinical laboratory Services. Labcorp makes no other express or implied commitments or warranties concerning the performance of the Study.

4.2 In the event that compliance with any new Regulatory Requirements necessitates a change in this Agreement, Labcorp will submit to Sponsor a revised technical and cost proposal for Sponsor’s acceptance prior to performing Services.

4.3 In the event of a material conflict in applicable Regulatory Requirements, the Sponsor will designate which regulations shall be followed by Labcorp in its performance of the Services and the Sponsor shall be fully responsible, to the extent permitted by law, for the outcome of such a decision.

5.1 Fees for the Project are set forth in the attached Budget. Sponsor acknowledges that SOW finalization, changes and/or modifications to the Project may result in a revised Budget. The Budget contains all the applicable discounts and Services that will be provided for that Project.

5.2 During performance of Services, Labcorp may be required to provide certain items including but not limited to ancillary supplies, logistics and minor modifications to database design (“Items”). Items may not appear in Sponsor’s Budget and will require written approval from Sponsor prior to the commencement of work on said items. Total fees for these items will be capped at $150,000. Sponsor agrees to remit payment for Items invoiced in accordance with payment terms provided in Section 5.4.

5.3 Upon execution, Labcorp will assess a fee equal to five per cent (5%) of the value of the contract Budget (Deposit). Sponsor will pay the Deposit within thirty (30) calendar days after receipt of invoice.

5.4 Each month, Labcorp will invoice Sponsor for all fees due and expenses incurred while providing Services during the previous month. Payment is due thirty (30) calendar days from invoice receipt. Payments not received within five business days of Labcorp’s notice to Sponsor of non-payment may be subject to a fifteen per cent (15%) per annum late payment fee.

5.5 Labcorp shall retain the Deposit until the Study invoices have reached ninety-five percent (95%) of the total Study Budget at which point the Deposit will be applied to monthly invoices. At the end of each Study, Labcorp shall conduct a final account reconciliation and will refund to Sponsor any remaining amounts of the Deposit within sixty (60) days after the date of the final invoice.

5.6 For budgeting purposes, Labcorp creates the Budget using local unit pricing. The local unit pricing is then converted to the billing currency, as requested by Sponsor, using the Reuters exchange rate for the month the Budget is first created. Unless specified otherwise, this exchange rate remains unchanged during the course of the Study to simplify budget comparisons and enable Sponsor to track changes to the Study unrelated to changes in currency exchange rates.

5.7 For invoicing purposes, Services are billed based on the contracted local unit prices. Each month, at the time of invoice creation, the local unit prices are converted to the billing currency using the Reuters exchange rate for the month in which the Services were performed.

5.8 Labcorp will hold prices unchanged for twelve (12) months from Project start up. Thereafter, fees may be adjusted annually by Labcorp upon thirty (30) days written notice to Sponsor.

5.9 Invoices will be provided by Labcorp to: ProKidney Accounts Payable ***@***
