SECTION 9 - INDEMNIFICATION AND INSURANCE 9.1 By CELGENE. CELGENE will defend, indemnify and hold harmless ENTREMED, its successors, AFFILIATES and licensors and their employees, agents, officers, trustees, shareholders and directors and each of them (the "ENTREMED Indemnified Parties") from and against any and all THIRD PARTY claims, causes of action and costs (including - 34 - <PAGE> reasonable attorney's fees) of any nature made or lawsuits or other proceedings filed or otherwise instituted against the ENTREMED Indemnified Parties in connection with any claims, suits or judgments arising out of any theory of product liability concerning the development, testing, manufacture, sale or use of any PRODUCT by CELGENE, its AFFILIATES or its SUBLICENSEES. 9.1.1 CELGENE's indemnification under this Section 9.1 shall not apply to any liability, damage, loss or expense to the extent that it is directly attributable to the negligent activity, reckless misconduct or intentional misconduct of ENTREMED. 9.1.2 Commencing not later than the date of FIRST COMMERCIAL SALE of a PRODUCT, CELGENE shall obtain and carry in full force and effect product liability insurance against any claims, judgments, liabilities and expenses for which it is obligated to indemnify ENTREMED and others under Section 9.1 of this Agreement, in such amounts and with such deductibles as are customary at the time for companies engaged in a similar business, and shall provide ENTREMED with written evidence of such insurance upon request. 9.2 By ENTREMED.

SECTION 12 - TERMINATION 12.1 Term.

If and only if ENTREMED exercises its right and option to terminate the license granted to CELGENE in - 39 - <PAGE> the entire TERRITORY, pursuant to Section 3.1(f) of this Agreement, or ENTREMED exercises its right and option to terminate the license granted to CELGENE in Europe, Canada, or the PACIFIC RIM, pursuant to Section 3.2(c)(i) of this Agreement, then, either in the entire TERRITORY or in the region in which such termination has occurred, i.e., Europe, Canada, or the PACIFIC RIM, as applicable: a) CELGENE's rights under this Agreement to ENTREMED INTELLECTUAL PROPERTY shall terminate; and b) CELGENE shall grant to ENTREMED, to the extent not prohibited by the United States Government or by prior contractual obligations to any THIRD PARTY, an exclusive, worldwide, royalty-free license, with the right to sublicense, under CELGENE DEVELOPED INTELLECTUAL PROPERTY to make, use, offer to sell, sell, and import PRODUCTS. The grant of rights by CELGENE to ENTREMED under this Section 12.4 expressly excludes rights in any CELGENE EXISTING INTELLECTUAL PROPERTY. (c) Termination under this Section 12.4 will be effective upon the date specified in the written notice. All termination rights shall be in addition to and not in substitution for any other remedies that may be available to the Non-Defaulting Party. Termination pursuant to this Section 12.4 shall not relieve the Defaulting Party from liability and damages to the Non-Defaulting Party for default.
