Seller shall make available the necessary records to permit Buyer to conduct an audit of the Final Settlement Statement during the forty-five (45) period commencing on the date the Final Settlement Statement is delivered to Buyer (the “Audit Period”). As soon as reasonably practicable, but no later the end of the Audit Period, Buyer may deliver to Seller a written report containing any changes Buyer proposes to such statement. Any matters covered by the Final Settlement Statement as delivered by Seller to which Buyer fails to object in the written report shall be deemed correct and shall be final and binding on the parties and not subject to further review, audit or arbitration. The undisputed amounts (net of any amounts in dispute) will be paid or collected promptly in cash only. The parties agree to negotiate in good faith to resolve any disputes relating to items in the Final Settlement Statement and shall meet no later than fifteen (15) days after Seller receives Buyer's written report to attempt to agree on any adjustments to the Final Settlement Statement. If the parties fail to agree on final adjustments within that fifteen (15) day period, either Party may submit the disputed items, no later than the thirtieth (30th) day following the expiration of such fifteen (I5) day period, to KPMG or another nationally-recognized, United States-based accounting firm on which the parties agree in writing (the “Accounting Referee”). Any adjustment dispute that is not resolved by agreement of the parties or submitted to the Accounting Referee by such thirtieth (30th) day shall be deemed waived unless the thirty (30) day period is extended by mutual written agreement of the parties. The parties shall direct the Accounting Referee to resolve the disputes within thirty (30) days after its receipt of relevant materials pertaining to the dispute. The Accounting Referee shall act as an expert for the limited purpose of determining the specific disputed matters submitted by either Party and may not award damages or penalties to either Party with respect to any matter. Seller and Buyer shall share equally the Accounting Referee's fees and expenses. The Final Settlement Statement, whether as agreed between the parties or as determined by a decision of the Accounting Referee, shall be binding on and non-appealable by the parties and not subject to further review, audit or arbitration. Payment by Buyer or Seller, as applicable, for any disputed amount on the Final Settlement Statement shall be made within five (5) Business Days after the earlier of (i) the date such amount is agreed, or deemed agreed, by the parties and (ii) the date the parties receive the Accounting Referee's decision (such earlier date being the “Final Settlement Date”).

(b) All claims for indemnification under this Agreement shall be asserted and resolved pursuant to this Section 9.5(b). Any person claiming indemnification hereunder is hereinafter referred to as the “Indemnified Party” and any person against whom such claims are asserted hereunder is hereinafter referred to as the “Indemnifying Party.” In the event that any Losses are asserted against or sought to be collected from an Indemnified Party by a third party, and a Party wishes to assert a claim for indemnity hereunder such Party shall with reasonable promptness provide to the Indemnifying Party a written notice of the indemnity claim it wishes to assert on behalf of itself or another Indemnified Party, including the specific details of and specific basis under this Agreement for its indemnity claim (a “Claim Notice”). A Party seeking indemnity by an Indemnifying Party hereunder shall provide its Claim Notice promptly after such Party has actual knowledge of the claim for which it seeks indemnification and shall enclose a copy of all papers (if any) served by a third party on the applicable Indemnified Party with respect to the claim; provided that the failure of any Party to give notice of a claim as provided in this Section shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the claim or otherwise prejudices the Indemnifying Party's ability to defend against the claim. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Losses that the Indemnifying Party elects to contest. Such cooperation shall include, without limitation, the retention and provision to the Indemnifying Party of all records and other information that are reasonably relevant to the Losses at issue.

Suspense Funds. The responsibility for payment of amounts held in suspense by Seller for periods prior to the Effective Date as to any of the Assets (such as suspended royalties held in the ordinary course of business as a result of title defects or changes of ownership) and the funds so held shall be transferred to Buyer at the Final Settlement Date (along with all reasonable supporting documentation to the extent in Seller's possession). After such time, any items accruing to suspense on account of production from the Assets shall be the responsibility of Buyer. From and after the Closing Date, Buyer shall assume all responsibility for such accounts and shall indemnify and hold Seller harmless from any claim or liability with respect thereto.
