The royalty term shall be adjusted in the event a Product is launched in any country of the Taisho Territory without such patent protection in such country, if such patent protection is later obtained. In such event, the above royalty obligation shall expire not upon expiration of the last such patent, but instead on an earlier date that precedes the expiration date of such patent by the length of time between launch and the date patent protection was obtained. 3.11 Payment; Reports. All amounts payable to Tularik under this Agreement shall be paid in U.S. Dollars within [ * ] after the end of each June and December.

Tularik shall have the right to cause an independent, certified public accountant to whom Taisho has no reasonable objection to audit such records to confirm Taisho's Net Sales and royalty payments; provided, however, that such auditor shall not disclose Taisho's confidential information to Tularik, except to the extent such disclosure is necessary to verify the amount of royalties due under this Agreement. Such audits may be exercised once a fiscal year, within three (3) years after the royalty period to which such records relate, upon notice to Taisho and during normal business hours. Tularik shall bear the full cost of such audit unless such audit discloses a variance of more than [ * ] from the amount of the Net Sales [ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange pursuant to Rule 406 of the Securities Act of 1933, as amended. 9 <PAGE> or royalties previously paid.
