D. Recoupment of Capital. No payments shall be made to RLV under its 22% NPI until both Amax and RLV have recouped from net operating cash flow from the Property all of their respective actual investments in the Property, including cumulative exploration, evaluation, and development expenditures ("Capital Investment") in the Property ("Payback"). The parties shall agree on the procedures by which Capital Investment is to be calculated. In recouping Capital Investment, the parties agree that each item of Capital Investment shall be recouped only once and neither party shall impose a "cost of capital" expense on the operation (but interest expense actually paid to third-party institutions will be considered part of Capital Investment). Prior to Payback for both Amax and RLV, the net operating cash flow shall be distributed 90% to Amax and 10% to RLV. If Amax reaches Payback before RLV, RLV shall receive 100% of the net operating cash flow until RLV Payback occurs. If RLV reaches Payback before Amax, Amax shall receive 100% of the net operating cash flow until Amax Payback occurs. Subsequent to Payback for Amax and RLV, all net operating cash flow shall be distributed to Amax, subject to RLV's 22% NPI. The distribution of net operating cash flow set forth in this Section 8D is subject to revision if so required by lending institutions providing financing for the project. If such institutions require a larger portion of cash flow to be dedicated to loan repayment, a revised distribution shall be agreed by the parties. E. Separate Mining Units. If separate mining units are created on the Property, each mining unit shall be treated as a stand-alone unit for the purpose of calculating production royalty and Payback. 9. Area of Interest. If either party or if any affiliate of a party now has or hereafter acquires any property interest within the boundaries of the Property or within one mile of the perimeter of such boundaries, such party shall give prompt notice to the other party and such property interests shall, at the option of the other party, exercised within 45 days after notice of such acquisition by the acquiring party, become part of the Property and become subject to this Agreement and to the definitive agreement described in Section 10 below (the "Additional Property"). The acquiring party shall be entitled to include all acquisition expense for such Additional Property in the calculation of its Capital Investment, for the purpose of Payback pursuant to Section 8D. If Amax does not exercise the Purchase Option and the Lease is terminated, RLV shall have the right to retain any Additional Property acquired by Amax, provided that RLV must reimburse Amax for its acquisition cost of the Additional Property within 30 days following such termination. 10.
