If BioChem, BV or TII does not exercise its Product Option for any CliniChem Product in any country prior to the expiration of such Product Option or, if BioChem, BV or TII notifies CliniChem expressly in writing that it will not exercise its Product Option for a CliniChem Product, BioChem shall make available to CliniChem for further development and commercialization activities, at no charge, all clinical supplies, materials and other tangible assets purchased, manufactured or developed for use exclusively in the development of such CliniChem Product (the "Development Assets") with respect to such country to the extent such assets are being used by CliniChem and will not be used under the Research and Development Agreement. 2.5 FAILURE TO EXERCISE PRODUCT OPTION. To the extent that BioChem, BV or TII does not exercise its Product Option with respect to any CliniChem Product, CliniChem will retain exclusive rights (subject to pre-existing third-party rights and subject to the receipt of certain third-party consents, as set forth in the Technology License Agreement) to develop and commercialize such CliniChem Product. 3. OBLIGATIONS WITH RESPECT TO ACQUIRED PRODUCTS. 3.1 DILIGENCE. Subject to Section 9.3 of this Agreement, if BioChem, BV or TII exercises its Product Option with respect to a CliniChem Product, such party shall use diligent efforts to conduct or have conducted any remaining activities necessary to complete the development of any Acquired Product through regulatory clearance to market the Acquired Product in each Major Market Country of the Territory; provided, however, that with respect to those Acquired Products for which BioChem, BV or TII has exercised its option to buy out royalty payments pursuant to Section 3.4 of this Agreement, such party shall have no such obligation. Such activities shall be undertaken at no cost to CliniChem, unless CliniChem agrees otherwise in writing. Promptly after regulatory clearance, BioChem or, to the extent applicable, BV or TII, shall commence and continue to use reasonable diligent efforts to commercialize the Acquired Product in each Major Market Country of the Territory through the manufacture and sale or the licensing of the Acquired Product, devoting to the Acquired Product the same resources as other pharmaceutical companies of similar size devote to products with similar market potential and with similar relative importance to their product portfolios. BioChem, BV and TII may use reasonable business discretion in the allocation of their technological and monetary resources in performing their obligations hereunder, taking into account not only the Acquired Product but also activities for their own account and their obligations under other agreements with third parties. CliniChem acknowledges that BioChem, BV and/or TII will continue to own and have the right to use any Development Assets relating to such Acquired Product without any additional payment to or reimbursement of CliniChem. -5- 6 3.2 PRODUCT PAYMENTS. BioChem, BV or TII, as applicable, shall make payments to CliniChem ("Product Payments") with respect to each Acquired Product as follows: (a) royalties of up to a maximum of six percent (6%) of Net Sales of the Acquired Product in the Territory determined as follows: (A) one percent (1%) of such Net Sales, plus (B) an additional one tenth of one percent (0.1%) of such Net Sales for each full one million dollars ($1,000,000) of Research and Development Costs of the Acquired Product that have been paid by CliniChem at the time BioChem, BV or TII exercised its Product Option with respect to such Acquired Product; plus (b) licensing fees of up to a maximum of twenty-five percent (25%) of Licensing Revenues received by the party exercising the Product Option with respect to such Acquired Product determined as follows: (A) ten percent (10%) of such Licensing Revenues, plus (B) an additional one percent (1%) of such Licensing Revenues for each full one million dollars ($1,000,000) of Research and Development Costs of the Acquired Product that have been paid by CliniChem at the time BioChem, BV or TII exercised its Product Option with respect to such Acquired Product. Notwithstanding the foregoing, Product Payments for any quarter will not exceed three percent (3%) of Net Sales plus twelve and one-half percent (12.5%) of Licensing Revenues in the Territory for the first twelve (12) calendar quarters during which the Acquired Product is commercially sold in the first Major Market Country. As a result of this provision, if an Acquired Product were to be cleared for marketing in countries that are not Major Market Countries prior to marketing clearance in the first Major Market Country and Product Payments in such countries would exceed three percent (3%) of Net Sales plus twelve and one-half percent (12.5%) of Licensing Revenues, the Product Payment rates in such countries will be reduced to three percent (3%) of Net Sales plus twelve and one-half percent (12.5%) of Licensing Revenues for the first twelve (12) calendar quarters during which the Acquired Product is commercially sold in the first Major Market Country. (c) In determining Product Payments, the amount of Net Sales by and Licensing Revenues of BioChem, BV and TII shall be reduced by the dollar amount of any license or similar payments made by or due from BioChem or its Affiliates to third parties with respect to sales or development of such Acquired Product in the Territory. BioChem, BV or TII, as applicable, shall allocate any such reduction between Net Sales and Licensing Revenues in a commercially reasonable manner. If license or similar payments are made to third parties with respect to sales of the Acquired Product in the Territory and to sales of other products, BioChem, BV or TII, as applicable, shall allocate such payments, if necessary, in a commercially reasonable manner. 3.3 TERM OF PAYMENT. The obligation to make Product Payments hereunder shall begin on the date of the first commercial sale of the Acquired Product in any country for which the Product Option has been exercised. Such obligation shall continue until ten (10) years after the date of the first commercial sale of the Acquired Product in any Major Market Country, and shall terminate as to all countries at the end of such ten (10) year period. -6- 7 3.4 BUY-OUT OF PAYMENTS. (a) BioChem, BV and TII shall have the option, in their discretion, at any time after the end of the twelfth calendar quarter during which the Acquired Product was commercially sold in any country, to buy out their respective remaining obligations to make Product Payments with respect to Net Sales and Licensing Revenues of such Acquired Product in such country. The buy-out price shall be an amount equal to fifteen (15) times the Product Payments made by or due from BioChem, BV or TII to CliniChem with respect to Net Sales and Licensing Revenues of such Acquired Product in such country for the four (4) calendar quarters immediately preceding the quarter in which the buy-out option is exercised, plus fifteen (15) times such additional Product Payments as would have been made but for the three percent (3%) of Net Sales plus twelve and one- half percent (12.5%) of Licensing Revenues limit set forth in Section 3.2 on Product Payments for such period. (b) BioChem shall have the option, in its discretion, at any time after the end of the twelfth calendar quarter during which the Acquired Product was commercially sold in either the United States or two other Major Market Countries, to buy out its remaining worldwide obligations to make Product Payments with respect to Net Sales and Licensing Revenues of such Acquired Product in the Territory. The buy-out price shall be an amount equal to (i) twenty (20) times (A) the Product Payments made by or due from BioChem, BV or TII to CliniChem for such Acquired Product in the Territory, plus (B) such payments as would have been made by or due from BioChem, BV or TII to CliniChem if BioChem had not exercised any country-specific buy-out option with respect to Net Sales and Licensing Revenues of such Acquired Product, plus (C) such additional Product Payments as would have been made but for the three percent (3%) of Net Sales plus twelve and one-half percent (12.5%) of Licensing Revenues limit set forth in Section 3.2 on Product Payments for such period, in each case, for the four (4) calendar quarters immediately preceding the quarter in which the buy-out option is exercised, less (ii) any amounts previously paid to exercise any country-specific buy-out option with respect to Net Sales and Licensing Revenues of such Acquired Product. 4. ACCOUNTING. 4.1 REPORTS. Within ninety (90) days after the end of each calendar quarter for which Product Payments are due, BioChem, BV and TII shall render an accounting to CliniChem, on a country-by-country basis, with respect to all Product Payments due for such quarter. Such report shall indicate, for such quarter, the quantity and dollar amount of Net Sales of and Licensing Revenues with respect to the Acquired Product by BioChem, BV, TII and their Affiliates or other consideration with respect to Net Sales and Licensing Revenues, with respect to which payments are due. In the event no Product Payments are due for any calendar quarter, BioChem, BV and TII shall so report. 4.2 RECORDS; REVIEW BY AUDITORS. BioChem, BV and TII shall keep and maintain, in accordance with Canadian generally accepted accounting principles, proper and complete records and books of account documenting all amounts paid or payable by BioChem, BV and TII to CliniChem.

Such examination shall take place not later than two (2) years following the year in question, and only one examination may take place with respect to any period as to which such books and records are examined. BioChem, BV and TII shall each use reasonable efforts to seek, for itself and for CliniChem, similar reasonable rights to audit information pertaining to Net Sales from each party appointed to commercialize any product as to which payments are due to CliniChem hereunder. 5. TIMES AND CURRENCIES OF PAYMENTS. 5.1 PAYMENTS. Payments shown by each calendar quarter report to have accrued shall be due and payable on the date such report is due and shall be paid in Canadian dollars. Any and all taxes due or payable on such payments or with respect to the remittance thereof shall be deducted from such payments and shall be paid by BioChem, BV or TII to the proper taxing authorities, and proof of payment shall be secured and sent to CliniChem as evidence of such payment. The rate of exchange to be used in computing the amount of the Canadian dollars due to CliniChem in satisfaction of payment obligations with respect to sales in foreign countries shall be calculated by converting the amount due in such foreign currency into Canadian dollars at the rate for the purchase of Canadian dollars with such currency as published in The Globe and Mail on the last business day of the calendar quarter for which payment is being made or the customary exchange rate posted by BioChem's bankers on such date. 5.2 CERTAIN FOREIGN PAYMENTS. If governmental regulations prevent remittance from any foreign country of any amounts due under Section 3.2 in respect of that country, BioChem, BV or TII shall so notify CliniChem in writing, and the obligation under this Agreement to make payments with respect to sales in that country shall be suspended (but the amounts due but not paid shall continue to accrue) until such remittances are possible. CliniChem shall have the right, upon written notice to BioChem, BV or TII, to receive payment in any such country in the local currency. 5.3 LATE PAYMENTS. Any payments due hereunder that are not made when due shall bear interest at the lesser of ten percent (10%) per annum or the maximum rate as may be allowed by law, beginning on the date when CliniChem has notified BioChem, BV or TII, as applicable, that such payments are overdue. 6. PATENT INFRINGEMENT. 6.1 NOTICE. Each party shall promptly notify the other in writing of any infringement or alleged infringement known to such party of any patent included in the BioChem Technology, by the manufacture, use, sale or offer for sale by a third party of any Infringing Product. 6.2 LEGAL ACTION. In the event of any infringement or alleged infringement as specified in Section 6.1, BioChem, BV and TII shall have the right, at their own expense, to take appropriate action to restrain such infringement or alleged infringement and for damages.
