TERM AND TERMINATION 7.1 This Agreement is effective as of the Effective Date and shall continue in full force and effect, with respect to a Party, on a country by country basis until the last expiration date of all patents encompassed within the Licensed Patents licensed to such Party hereunder. 7.2 If a Party shall fail in any material respect to perform or observe any term, covenant or understanding contained in this Agreement or in any of the other documents or instruments delivered pursuant to, or concurrently with, this Agreement, and any such failure shall remain unremedied for 90 days after written notice to the defaulting Party, the Party not responsible may, by notice to the defaulting Party, terminate the license granted by such Party to the defaulting Party. 7.3 OSI shall have the right to terminate the Agreement if either AHPC or ACC makes an assignment for the benefit of its creditors, becomes insolvent, files a petition in bankruptcy, petitions or applies to any tribunal for the appointment of a custodian, receiver or any trustee for it or a substantial part of its assets, or commences any proceeding under any bankruptcy, reorganization, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction, whether now or hereafter in effect; or if there has been filed any such petition or application against either AHPC or ACC, or any such proceeding has been commenced against it, in which an order for relief is entered or which remains 7 9 undismissed for a period of 60 days or more; or if either AHPC or ACC, by any act or omission, indicates its consent to, approval of or acquiescence in, any such petition, application or proceeding or order for relief or the appointment of a custodian, receiver or any trustee for it or any substantial part of any of its properties, or is the subject of any such custodianship, receivership or trusteeship that continues undischarged for a period of 60 days or more. 7.4 AHPC and ACC shall have the right to terminate the Agreement if OSI makes an assignment for the benefit of its creditors, becomes insolvent, files a petition in bankruptcy, petitions or applies to any tribunal for the appointment of a custodian, receiver or any trustee for it or a substantial part of its assets, or commences any proceeding under any bankruptcy, reorganization, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction, whether now or hereafter in effect; or if there has been filed any such petition or application against OSI, or any such proceeding has been commenced against it, in which an order for relief is entered or which remains undismissed for a period of 60 days or more; or if OSI, by any act or omission, indicates its consent to, approval of or acquiescence in, any such petition, application or proceeding or order for relief or the appointment of a custodian, receiver or any trustee for it or any substantial part of any of its properties, or is the subject of any such custodianship, receivership or trusteeship that continues undischarged for a period of 60 days or more. 8. MISCELLANEOUS 8.1 Binding Effect; Assignment. This Agreement shall be binding upon the Parties' respective successors and permitted assigns. Neither Party may assign this Agreement or any of its rights or obligations hereunder without the prior written consent of the other Party (not to be unreasonably withheld) except that either Party may assign this Agreement as part of a merger or consolidation in which the surviving entity assumes all of the Party's rights and obligations hereunder or a sale of substantially all of the assets of such Party to which this Agreement relates. In addition, if AHPC sells to a Third Party all of the stock of ACC or if ACC sells all or substantially all of its assets to a Third Party, AHPC or ACC, as the case may be, may assign the license granted by OSI in Section 2.1 to such Third Party purchaser, without the consent of OSI, only to the extent that such license is for the research and development of products for agricultural purposes (i.e., subsection (b) of Section 1.1), provided that such Third Party purchaser assumes the obligations of AHPC or ACC, as the case 8 10 may be, to grant the license set forth in Section 2.2. In the event of such a sale, the license granted in Section 2.1 to AHPC shall remain in effect as to AHPC and its Affiliates only with respect to the research and development of products for human therapeutic purposes (i.e., subsection (a) of Section 1.1). 8.2 Effect of Waiver. No waiver of any default, condition, provisions or breach of this Agreement shall be deemed to imply or constitute a waiver of any other default, condition, provision or breach of this Agreement. 8.3 Force Majeure. No Party shall lose any rights hereunder or be liable to the other Parties for damages or losses (except for payment obligations) on account of failure of performance by the defaulting Party if the failure is occasioned by war, strike, fire, acts of God, earthquake, flood, lockout, embargo, governmental acts or orders or restrictions, failure of suppliers, or any other reason where failure to perform is beyond the reasonable control and not caused by the negligence or intentional conduct or misconduct of the nonperforming Party, and such Party has exerted all reasonable efforts to avoid or remedy such force majeure; provided, however, that in no event shall a Party be required to settle any labor dispute or disturbance. 8.4 Amendment. No modification, supplement to or waiver of this Agreement or any of the provisions hereof or any Exhibit hereto shall be binding upon a Party hereto unless made in writing and duly signed by an authorized representative of OSI, AHPC or ACC. 8.5 Entire Agreement.

It is further the intention of the Parties that in lieu of each such provision which is invalid, illegal, or unenforceable, there shall be substituted or added as part of this Agreement by such court of competent jurisdiction a provision which shall be as similar as possible in terms of the economic and business objectives intended by the Parties, to such invalid, illegal or unenforceable provision, but shall be valid, legal and enforceable. 8.9 Independent Contractors.
