The above schedule shall start anew on January 1 of each calendar year.

Except as provided in Section 1.7.2, sales to an End User shall be deemed to have been made on the date of shipment.

3.4. LICENSEE shall have, at its option, the right to replace the royalty schedule set forth in Section 3.1 hereof or the method of calculating the royalty base (defined in this Agreement as “Net Annual Sales”) with any more favorable sublicense royalty rate or royalty base calculation method hereafter granted in the same Field of Use by LICENSOR or any assignee or successor of LICENSOR for sales to End Users, except that (i) such right shall not extend to any royalty rate or royalty base calculation method contained in any sublicense granted to any affiliate of LICENSOR or to [CONFIDENTIAL TREATMENT REQUESTED] /*/ or in any sublicense granted as part of a bona fide cross-licensing arrangement or in settlement of a claim, and (ii) to the extent that LICENSOR or its assignee or successor grants a more favorable sublicense royalty rate or royalty base calculation method that is limited to some portion of the Field of Use, LICENSEE shall be entitled to such more favorable rate or method only with respect to products sold in said limited portion of the Field of Use. Any cross-licensing arrangement shall be deemed to be bona fide unless LICENSOR’s purpose in entering such cross-license was to avoid its obligations under this subparagraph.

3.5. LICENSEE shall be liable for interest on any overdue royalty payments, commencing on the date any such payment becomes due, at an annual rate which is the greater of ten percent (10%) or one percentage point higher than the prime interest rate as quoted by the head office of Citibank, New York, New York, at the close of banking on such date, or on the fast business day thereafter if such date falls on a non-business day. If such interest rate exceeds the maximum legal rate in the jurisdiction where a claim therefor is being asserted, the interest rate shall be reduced to such maximum legal rate, to the extent that such interest rates are subject to the laws of such jurisdiction.

3.6. In the event an audit under the provisions of Section 4 hereof identifies an underpayment of royalties by LICENSEE, LICENSEE shall pay an amount equal to such underpayment within [CONFIDENTIAL TREATMENT REQUESTED] /*/ days of LICENSOR’s written request together with the interest due on such amount pursuant to the provisions of Section 3.5 above.

4.7. LICENSEE shall prepare and retain records in sufficient detail to permit the determination of products subject to this Agreement, the royalties due LICENSOR, and the accuracy of the information on LICENSEE’s written reports. Such records shall include, but not be limited to, detailed sales records supporting the information provided under Section 4.4.
