In consideration of one Party (the “Disclosing Party”) making available its Confidential Information to the other (the “Recipient Party”), the Recipient Party hereby undertakes that it shall, and shall procure that each of its Permitted Recipients, shall:

treat and safeguard as private and confidential all the Confidential Information;

use the Confidential Information only during the Term for those purposes reasonably necessary for or anticipated under this Agreement and without prejudice to the generality of the foregoing, not use any Confidential Information to obtain any commercial advantage over the Disclosing Party;

ensure the proper and secure storage of all Confidential Information applying standards of care reasonably expected and no less stringent than standards applied to protection of Recipient Party's own confidential information; and

not at any time without the Disclosing Party’s prior written consent disclose or reveal, whether directly or indirectly, any of the Confidential Information to any person whatsoever except its Permitted Recipients, and then only on a limited need to know basis, who shall be informed by it of the confidential nature of the Confidential Information and of the confidentiality terms of this Agreement and for whom it hereby accepts full responsibility in the event that any such person shall breach the duty of confidence imposed upon them;

The obligations in this Agreement regarding Confidential Information do not apply to information:

which, at the time of its disclosure by the Disclosing Party, was available to the public and could be obtained without reference to the Confidential Information by any person with no more than reasonable diligence;

which becomes generally available to the public after such disclosure otherwise than by reason of a breach of any of the undertakings in this Agreement or any breaches of confidence by the Recipient Party or its Permitted Recipients;

which is, at the time of such disclosure and as evidenced by the Recipient Party's written records, lawfully already within its possession; or

to the extent that the Recipient Party or any of its Permitted Recipients is compelled to disclose the Confidential Information by law or by any stock exchange or other regulatory authority having jurisdiction over it or them.

CONFIDENTIAL

Other than the limited and restricted rights of use set out in this Section 10 nothing in this Agreement intends to or has the effect of granting any right, title, license or interest in or to the Recipient Party or Permitted Recipients in respect of the Disclosing Party's Confidential Information.

If the Recipient Party or any of its Permitted Recipients becomes aware of any misuse of the Confidential Information, compelled to disclose any Confidential Information in the circumstances described in Section 10.2.4 of this Agreement or a breach or threatened breach of this Section 10 occurs or becomes apparent, the Recipient Party shall inform the Disclosing Party in writing of such obligation or fact as soon as possible after it is informed, or becomes aware, of it and if possible, before any Confidential Information is disclosed, so that (if the Disclosing Party in its absolute discretion shall see fit) a protective order or other appropriate remedy may be sought. The Recipient Party agrees to assist and co‑operate (and shall procure that each of its Permitted Recipients shall, as appropriate, assist and co-operate) in any action which the Disclosing Party may decide to take. The Recipient Party shall notify the Disclosing Party prior to each disclosure of Confidential Information if it is under any obligation which would or might compel it to disclose any Confidential Information and subsequent to such disclosure it shall not voluntarily assume any such obligation.

Except as otherwise provided for in this Agreement or otherwise required by law or administrative authorities, neither Customer nor CMC shall disclose any terms or conditions of the Agreement to any third party without the prior written consent of the other Party.

Upon termination or expiry of this Agreement or at the request of the Disclosing Party, the Recipient Party shall promptly destroy (on request) or return to the Disclosing Party any and all Confidential Information (including copies of documents, computer records and records on all other media) then in its possession or under its control except where such Confidential Information is covered under surviving license rights between the Parties. Notwithstanding the foregoing, the Parties may retain a single copy of any document contained the Disclosing Party's Confidential Information solely for the purpose of determining the scope of the obligations under this Agreement.

The Parties acknowledge that they have received Confidential Information under the Existing Agreement.  The Parties hereby agree that Confidential Information received under the Existing Agreement may be used for the purposes of performing the Services under this Agreement.  

The Parties acknowledge that any breach or threatened breach of this Section 10 by the Recipient Party may cause immediate and irreparable harm to the Disclosing Party that may not be adequately compensated by damages.  Each Party therefore agrees that in the event of such breach or threatened breach by the Recipient Party, the Disclosing Party shall be entitled to obtain timely injunctive relief, without the posting of a bond or other security, as well as such further relief as may be granted by a court of competent jurisdiction.    

The provisions of this Section 10 shall survive termination or expiration of the Agreement for a period of [*] years.
