The Transition Fee and the fee for Other Services provided shall be due and payable by TriQuint Germany to Infineon by wire transfer of immediately available funds within thirty (30) days after such written statement is sent to TriQuint Germany from Infineon. Notwithstanding this paragraph, amounts due and payable pursuant to Schedule 1 shall be due and payable according to the terms thereof.

TriQuint Germany shall have no right to set-off against any claims for payment of the Transition Fee or of the fee for Other Services provided to be made by TriQuint Germany pursuant to this Agreement, any claims for payment of TriQuint Germany resulting from the Acquisition Agreement.

Infineon shall have the right, at its option, to discontinue providing the respective Transition Services and/ or the respective Other Services if full payment of fees for the respective Services is not received from TriQuint Germany in a timely manner. This provision shall not apply, however, in case that TriQuint Germany delivers written notice to Infineon that it in good faith disputes the amount it was billed for the respective Services. In such case TriQuint Germany and Infineon will negotiate in good faith to resolve such dispute and Infineon will continue to render the respective Services and TriQuint Germany will pay the amount which is not in dispute pending the resolution of any such good faith dispute.

Furthermore, the parties agree that in the event of a discontinuance of Services for nonpayment pursuant to the provision above, Infineon will as promptly as reasonably practicable recommence such Services upon full payment by TriQuint Germany of such amount of fees owed.
