10.7. Net Losses and Subrogation.

(a) Notwithstanding anything contained herein to the contrary, the amount of any Losses incurred or suffered by a Person entitled to indemnification hereunder (an “Indemnified Person”) shall be calculated after giving effect to (i) any insurance proceeds received by the Indemnified Person (or any of its Affiliates) with respect to such Losses reduced to the extent of any actual increase in insurance premiums arising from the insurer’s payment with respect to such Losses, (ii) any Tax benefit realized by the Indemnified Person (or any of its Affiliates) arising from the facts or circumstances giving rise to such Losses and realized by the Indemnified Person, and (iii) any recoveries obtained by the Indemnified Person (or any of its Affiliates) from any other third party. Each Indemnified Person shall exercise commercially reasonable efforts to obtain such proceeds, benefits and recoveries where commercially reasonable to do so. If any such proceeds, benefits or recoveries are received by an Indemnified Person (or any of its Affiliates) with respect to any Losses after an Indemnified Person with respect thereto, the Indemnified Person (or such Affiliate) shall pay to the person providing the indemnification (the “Indemnifying Person”) the amount of such proceeds, benefits or recoveries (up to the amount of the Indemnifying Person’s payment). Any Tax benefit realized by the Indemnified Person pursuant hereto shall be calculated based on the highest marginal federal and state tax rate for Buyer or Seller Entities, as applicable, and assuming that the Tax benefit can be fully utilized, either currently or in a carryback. Any Tax benefit derived from depreciation or amortization shall be based on the present value of the Tax benefit computed using the prime lending rate of Citibank at the time of computation of the indemnity at issue.

(b) Upon making any payment to an Indemnified Person in respect of any Losses, the Indemnifying Person will, to the extent of such payment, be subrogated to all rights of the Indemnified Person (and its Affiliates) against any third party in respect of the Losses to which such payment relates. Such Indemnified Person (and its Affiliates) and Indemnifying Person will execute upon request all instruments reasonably necessary to evidence or further perfect such subrogation rights.
