Third Party Infringement Claims If a Third Party Infringement Claim occurs in the Territory with respect to one or more elements of the RLS Licensed Technical Information or RLS Licensed Software, or in Teletrac's opinion is likely to occur, Teletrac will use reasonable commercial efforts, at its option and expense, either to challenge such Third Party Infringement Claim or otherwise procure for Licensee the right to continue to use, maintain and provide support for the Radio Location System, or to replace or modify the alleged infringing element so that such element becomes non-infringing, provided that such replacement or modification does not materially affect performance of the Radio Location System. If Teletrac has spent, or anticipates that it will be required to spend, more than U.S. $100,000 for such efforts, then Teletrac may give Licensee a ninety (90) day option to pursue such efforts on its own and at its own expense. If Licensee elects to pursue such efforts on its own, then Licensee may deduct from the Annual Royalty Payments due to Teletrac in the future, the reasonable expenses Licensee has incurred in obtaining non-infringing elements, up to a maximum amount of U.S.$250,000. If Licensee has not elected to pursue such efforts on its own within such ninety (90) day option period, then Licensee must notify Teletrac in writing either (i) that this License Agreement shall continue in full force and effect without regard to such Third Party Infringement Claim and without any reduction in the Annual Royalty Payment, or (ii) that Licensee elects to terminate this License Agreement due to such Third Party Infringement Claim, which shall be deemed to be a termination under Section 7.1. If the use of any RLS Licensed Software or RLS Licensed Technical Information is enjoined and the foregoing remedies cannot reasonably be accomplished, or if Licensee elects to continue this License Agreement but fails to procure the right to use the infringing element or to replace or modify the infringing element so that it becomes non-infringing, then Teletrac may require the return of the infringing RLS Licensed Software or RLS Licensed Technical Information, and Licensee's right to use such RLS Licensed Software or RLS Licensed Technical Information shall thereupon terminate. In no event shall Teletrac have any obligation to repay or refund any amounts previously paid to it by Licensee.
