Channel Inventory. From and after the Commencement Date, all amounts received by Riverdeep on account of Product distributed into the Channel shall be payable to Distributor, and to the extent any such funds are received by Riverdeep, the same shall be reported and paid thereto within fifteen (15) days of receipt thereof. During the Term, Distributor shall: (a) accept returns of Channel Inventory; and (b) provide Distributor's retail accounts with the Channel Inventory Credits.

(ii) If upon the receipt of a Third Party Consent and application of the applicable increase to the Guaranteed Royalty (each, a "Third Party Consent Increase") payments by Distributor to Riverdeep prior to the application of the Third Party Consent Increase were insufficient to cover the Guaranteed Royalty (including the retroactive application of the Third Party Consent Increase), Distributor shall make a "catch up" payment in an amount equal to the difference between the amount actually paid by Distributor to Riverdeep prior to the application of the Third Party Consent Increase and the amount of the Guaranteed Royalty following the application of the Third Party Consent Increase. This catch-up payment, if any, shall be payable by Distributor to Riverdeep not later than 30 days following the application of a Third Party Consent Increase. Thereafter, subject to adjustment pursuant to the terms and conditions set forth in the Agreements, the Guaranteed Royalty shall be increased by the amount of the Third Party Consent Increase. 4.
