(d) Buyer will forward to Seller copies of any reports received from or on behalf of Celgene in any way relating to Applicable Net Sales, Celgene Cumulative Net Sales and/or the Net Celgene Payments within 10 business days after receipt thereof by Buyer.

Buyer shall keep full and accurate books of account containing all particulars relevant to its receipt of Applicable Net Celgene Payments and other records that may be necessary for the purpose of determining whether and when any -7- <PAGE> 11 amounts are payable by Buyer to Seller under Section 2.05 hereof or this Section 2.06. Such books of account shall be kept at a place of business in the United States and shall be open for inspection by an independent certified public accountant reasonably acceptable to Buyer upon reasonable notice during normal business hours at Seller's expense, for the sole purpose of verifying compliance with this Agreement; provided, however, that Buyer shall have no obligation to open such books of account for inspection until the earlier to occur of (i) such time as any amounts are payable by Buyer to Seller or (ii) such time as Seller reasonably believes that any payments should have been made to Seller by Buyer under Section 2.05 hereof or this Section 2.06. In the event the inspection determines that amounts due Seller for any period have been underpaid by five percent (5%) or more, then Buyer shall pay for all costs of the inspection. All information and data reviewed in the inspection shall be used only for the purpose of verifying royalties and shall be treated as confidential information. No inspection by an agent of Seller shall occur more frequently than once during any twelve (12) month period. 2.07. OFFSET. Notwithstanding anything to the contrary in Sections 2.05 and 2.06, the provisions of this Section 2.07 shall apply. If Seller owes any amount to Buyer or its Affiliates pursuant to Article VII of this Agreement, and such amount shall have been finally determined by written agreement with Seller or by final judgment for which the time of appeal has expired, then Buyer shall be entitled to offset against any amount payable to Seller under Section 2.05 or 2.06 the amount so owed to Buyer or its Affiliates. If Buyer or any of its Affiliates has claimed any amount from Seller pursuant to Article VII of this Agreement, but there shall not yet be any such written agreement or final judgment, Buyer shall pay to an escrow agent, which shall be a financial institution located in the United States with which neither Buyer nor Seller has a material relationship, out of the amount payable pursuant to Section 2.05 or 2.06, an amount equal to the amount claimed by Buyer or its Affiliates, such amount to be held in escrow subject to joint instructions from Buyer and Seller. If it shall be agreed or determined that Seller owes Buyer or its Affiliates any amount, then Buyer and Seller shall execute joint instructions to the escrow agent to deliver, out of the funds held in escrow, such amount to Buyer and the remaining amount, if any, to Seller. If it shall be agreed or determined that Seller owes no amount to Buyer or its Affiliates, then Buyer and Seller shall execute joint instructions to the escrow agent to deliver the entire amount of the funds held in escrow to Seller. Buyer shall bear the costs of the escrow agent if Seller is entitled to the escrowed funds. Seller shall bear the costs of the escrow agent if Buyer or its Affiliates are entitled to the escrowed funds. If any portion of the escrowed funds are payable to Buyer, then the costs of the escrow agent shall be borne pro rata, the largest portion by the Person paid the smallest portion of the escrowed funds.

Except as set forth on Appendix D to the Celgene Agreement and Schedule 3.08(g), to Seller's knowledge, there does not exist any Third Party patent or patent application that contains any interfering subject matter, nor any issued Third Party patents that would be infringed by the making, using, selling, offering for sale, or importing by Celgene of Products covered by the EntreMed Existing Patent Rights or the EntreMed Existing Technology Rights in any country in the Territory, nor by the exercise by Celgene of any right granted to it under the Celgene Agreement. All capitalized terms used in this Section 3.08(g) but not defined herein shall have the meanings ascribed to such terms in the Celgene Agreement. 3.09. CMCC AGREEMENT. (a) Terms Unmodified. A true, correct and complete copy of the CMCC Agreement is attached hereto as Exhibit C. The CMCC Agreement is in full force and effect in the form attached hereto as Exhibit C, and has not been altered or modified in any respect.

(c) No Satisfaction or Discharge; Entire Agreement. The CMCC Agreement has not been satisfied, discharged, canceled, terminated, subordinated or rescinded, in whole or in part. The CMCC Agreement is the entire agreement between Seller and CMCC relating to the subject matter thereof and, other than the Celgene Agreement, constitutes the only agreement or instrument to which Seller is a party that relates to the Net Celgene Payments.

(e) License. Seller has, pursuant to the CMCC Agreement, the exclusive worldwide right and license to use, lease and sell the Licensed Products (which are sublicensed to Celgene pursuant to the Celgene Agreement), and to practice the Licensed Processes (which are sublicensed to Celgene pursuant to the Celgene Agreement) to the end of the term for which the Patent Rights are granted unless sooner terminated. On the Closing Date, after consummation of the transactions contemplated by this Agreement, Seller will no longer have any such right or license.

Subject to the terms and conditions of this Agreement, each party will use its commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary under applicable laws and regulations to consummate the transactions contemplated by this Agreement; -14- <PAGE> 18 provided that Buyer shall not be obligated to pay any amount of money or deliver any goods or services to Seller or any third party except as otherwise expressly provided in this Agreement. Buyer and Seller agree to execute and deliver such other documents, certificates, agreements and other writings (including any UCC filings requested by Buyer) and to take such other actions as may be reasonably necessary in order to consummate or implement expeditiously the transactions contemplated by this Agreement. 5.06. SELLER'S CONTINUING COVENANTS. (a) If Celgene should exercise its right to reduce any royalty payments pursuant to Section 7.3(g) of the Celgene Agreement or that section of the New Thalidomide Agreement that is equivalent to Section 7.3(g) of the Celgene Agreement, and such exercise results in a reduction in any Net Celgene Payments, then Seller shall, promptly after notice from Buyer that such right to reduce royalty payments has been exercised, pay to Buyer the amount that Celgene applied in such reduction. Seller's obligations under this Section 5.06(a) shall expire on the due date, if it shall occur, for payment of the Contingent Purchase Price pursuant to Section 2.05(a) hereof. (b) From and after the Closing Date until such time as Buyer shall have received the last Net Celgene Payment under the New Thalidomide Agreement (or any amendment, modification or successor agreement thereto), Seller shall: (i) Upon the request of Buyer, from time to time execute, acknowledge and deliver, or cause to be executed, acknowledged and delivered, such further instruments and take such further action as may be reasonably necessary to effectuate the intention, performance and provisions of this Agreement; (ii) Provide Buyer, as promptly as practicable (and in any event within three business days of Seller's receipt thereof), of (A) copies of any correspondence or other written communication from CMCC relating to thalidomide or from Celgene relating to thalidomide and (B) notice (in writing in reasonable detail) of any oral communication from CMCC or Celgene which could reasonably be understood to be a material development with respect to thalidomide; and (iii) Cooperate and provide assistance as reasonably requested and to the extent reasonably necessary in connection with any litigation, arbitration or other proceeding (whether threatened, existing, initiated, or contemplated prior to, on or after the date hereof) to which Buyer, its affiliates or any of its officers, directors, shareholders, agents or employees is or may become a party or is or may become otherwise directly or indirectly affected or as to which any such Persons have a direct or indirect interest relating to this Agreement, the Net Celgene Payments or the transactions described herein or therein. With respect to the foregoing obligations, it is understood that, as result of the New Thalidomide Agreement, Buyer may bring actions against Celgene directly and, therefore, it is expected that the need for Seller's cooperation and assistance, if any, will be limited. Buyer shall reimburse Seller for reasonable out-of-pocket expenses (including -15- <PAGE> 19 the reasonable fees and expenses of counsel) incurred by Seller in connection with the foregoing cooperation and assistance. 5.07. BUYER'S CONTINUING COVENANTS.
