5. CONFIDENTIALITY

(a) Confidential Information. All information that is disclosed or provided by one Party (in each case, the “Disclosing Party”) to any other Party (each, the “Recipient”) pursuant to this Agreement, whether in oral, written, graphic, electronic, or any other form, shall be the “Confidential Information” of the Disclosing Party. Except to the extent expressly authorized by this Agreement or by the other Party in writing, during the term of this Agreement and for five years thereafter, each Party shall maintain in strict trust and confidence and shall not disclose to any third party or use for any purpose other than as provided for in this Agreement any Confidential Information of the other Party. Each Party may use the other Party’s Confidential Information only in connection with the exercise of rights granted to such Party hereunder, and for no other purpose. Each Party agrees that it shall not use the other Party’s Confidential Information for any purpose or in any manner that would constitute a violation of applicable laws.

(b) Exceptions. The obligations of confidentiality and nonuse set forth in Section 5.1(a) shall not apply to any specific portion of information that the Recipient can demonstrate by competent written proof: (i) is in the public domain or comes into the public domain through no fault of the Recipient; (ii) is furnished to the Recipient by a third party rightfully in possession of such information and not subject to a duty of confidentiality with respect thereto; (iii) is already known by the Recipient at the time of receiving such Confidential Information from the Disclosing Party as evidenced by the Recipient’s prior written records; or (iv) is independently developed by the Recipient without access to the Disclosing Party’s Confidential Information.

(c) Authorized Disclosure. Notwithstanding the foregoing in this Section 5, the Recipient may disclose certain Confidential Information of the Disclosing Party to the extent such disclosure is required by law or regulation, or pursuant to a valid order of a court or other governmental body having jurisdiction; provided that the Recipient provides the Disclosing Party with reasonable prior written notice of such disclosure and reasonable assistance in obtaining a protective order or confidential treatment preventing or limiting the disclosure and/or requiring that the Confidential Information so disclosed be used only for the purposes for which the law or regulation required, or for which the order was issued.

(d) Return of Confidential Information. Upon termination or expiration of the Agreement, or upon written request of the Disclosing Party, the Recipient shall promptly return to the Disclosing Party or destroy all documents, notes and other tangible materials representing the Disclosing Party’s Confidential Information and all copies thereof; provided, however, that each Party may retain (i) a single archival copy of the other Party’s Confidential Information for the sole purpose of facilitating compliance with the surviving provisions of this Agreement and (ii) computer generated back-up copies that are difficult to locate.

(e) Injunctive Relief. The parties expressly acknowledge and agree that any breach or threatened breach of this Section 5 may cause immediate and irreparable harm to the non-breaching Party that may not be adequately compensated by damages. Each Party therefore agrees that in the event of such breach or threatened breach and in addition to any remedies available at law, the non-breaching Party shall have the right to secure equitable and injunctive relief, without the necessity of securing bond, in connection with such a breach or threatened breach.

6. TERM This Agreement shall become effective on the date hereof and shall continue in effect as long as any Genzyme Royalties or Tufts Royalties are due and payable under Genzyme Agreement or Tufts Agreement unless sooner terminated upon the mutual agreement of rEVO and LFB USA. Notwithstanding the foregoing, the provisions of Section 3 (Records; Audits), Section 5 (Confidentiality), this Section 6 (Term), Section 7 (Dispute Resolution) and Section 8 (Miscellaneous) shall survive any such expiration or termination of this Agreement.
