The amount of the actual loss and the amount of the indemnity payment shall be computed by taking into account the timing of the loss or payment, as applicable, using a Prime Rate plus 2% interest or discount rate, as appropriate (not to exceed the maximum rate permitted by applicable Law). Upon the request of the Indemnifying Party, the Indemnified Party shall provide the Indemnifying Party with information sufficient to allow the Indemnifying Party to calculate the amount of the indemnity payment in accordance with this Section 8(f) . Each Party shall use its Commercially Reasonable Efforts to recover under insurance policies or similar agreements for any Losses prior to seeking indemnification under this Agreement. If the Indemnified Party receives insurance proceeds for Obligations after an indemnification payment for such Losses has been made by the Indemnifying Party to the Indemnified Party, the Indemnified Party will refund the Indemnifying Party the amount of such insurance proceeds received by the Indemnified Party.
