NOW, THEREFORE, in consideration of the covenants and agreements herein set forth and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Parties agree as follows:

1.                                      Termination .  The Parties hereby agree that the Combination Agreement, including all schedules and exhibits thereto, and all ancillary agreements contemplated thereby, including the Ancillary Agreements (other than the Confidentiality Agreement) and the irrevocable undertakings executed by certain shareholders of Oxford in favor of Cambridge and Oxford (collectively, the “ Transaction Documents ”), are hereby terminated effective immediately (the “ Termination Time ”) and, notwithstanding anything to the contrary in the Transaction Documents, including Section 11.2 of the Combination Agreement, the Transaction Documents are terminated in their entirety and shall become null and void and be of no further force or effect whatsoever (the “ Termination ”).

Each of the Releasors hereby expressly waives to the fullest extent permitted by Law the provisions, rights and benefits of California Civil Code section 1542 (or any similar Law), which provides:

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.

Nothing in this Section 3 shall (i) apply to any action by any Party to enforce the rights and obligations imposed pursuant to this Agreement or the Confidentiality Agreement or (ii) constitute a release by any Party for any Claim arising under this Agreement or the Confidentiality Agreement.

4.                                      Publicity .  The Parties mutually agree to issue a joint press release in the form attached hereto as Exhibit A regarding this Agreement and the Termination.

8.                                      Entire Agreement .  This Agreement and the Confidentiality Agreement constitute the entire agreement of the Parties with respect to the subject matter hereof and supersede all prior representations, warranties, agreements and understandings, both written and oral, between the Parties or any of them with respect to the subject matter hereof.

9.                                      Governing Law and Venue .  THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN, AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN, ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE WITHOUT REGARD TO ITS RULES OF CONFLICTS OF LAW THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY STATE OTHER THAN THE STATE OF DELAWARE. The Parties hereby irrevocably submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware located in Wilmington, Delaware, or, in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, the federal courts of the United States of America located in the City of Wilmington in the State of Delaware in respect of all matters arising out of or relating to this Agreement, the interpretation and enforcement of the provisions of this Agreement, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the Parties irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined exclusively in such courts. The Parties hereby consent to and grant any such court jurisdiction over the person of such Parties solely for such purpose and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 12.1 of the Combination Agreement or in such other manner as may be permitted by applicable Laws shall be valid and sufficient service thereof.

10.                               Counterparts; Effectiveness .  This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which, when taken together, shall constitute one and the same instrument. This Agreement shall become effective when each Party shall have received counterparts thereof signed and delivered by the other Parties. Signatures transmitted electronically shall be accepted as originals for all purposes of this Agreement.

11.                               Specific Performance .  The Parties agree that irreparable injury will occur in the event that any of the provisions of this Agreement is not performed in accordance with its specific terms or is otherwise breached.  Each Party shall be entitled to an injunction or injunctions to prevent or remedy any breaches or threatened breaches of this Agreement by any other Party, to a decree or order of specific performance to specifically enforce the terms and provisions of this Agreement and to any further equitable relief.  The Parties’ rights in this Section 11 are an integral part of this Agreement and each Party hereby waives any objections to any remedy referred to in this Section 11 (including any objection on the basis that there is an adequate remedy at Law or that an award of such remedy is not an appropriate remedy for any

3

reason at Law or equity).  For the avoidance of doubt, each Party agrees that there is not an adequate remedy at Law for a breach of this Agreement by any Party.  In the event any Party seeks any remedy referred to in this Section 11 , such Party shall not be required to obtain, furnish, post or provide any bond or other security in connection with or as a condition to obtaining any such remedy.
