The parties hereby agree as follows:

The parties also agree that all Affiliates and agents of the parties to whom confidential information is disclosed will be bound by the provisions of this Section 5 and that the parties will be responsible for any breaches by their respective Affiliates or agents of the terms of this Section 5. If a party (the “Disclosing Party”) receives a request to disclose all or any part of the confidential information of another party (the “Target Party”) under the terms of a valid and effective subpoena, decree or order issued by a court of competent jurisdiction or by a governmental body, such party hereby agrees to, and agrees to cause its Affiliates to: (a) immediately notify the Target Party in writing of the existence, terms and circumstances surrounding the request so that the Target Party may seek an appropriate protective order or waive the Disclosing Party’s compliance with the provisions of this Agreement (and, if the Target Party seeks an order, to provide the cooperation as the Target Party shall reasonably request); and (b) if disclosure of the Target Party’s confidential information is required in the written opinion of the Disclosing Party’s counsel, then the Disclosing Party shall exercise reasonable efforts, with the cooperation of the Target Party, to obtain an order or other reliable assurance that confidential treatment will be accorded to the disclosed the Target Party’s confidential information that the Target Party so designates.

5.1.6                     Each party hereby agrees that the breach of this Section 5 would cause irreparable harm to the non-breaching party or parties for which money damages would not be adequate compensation. If any party, or any Affiliate or agent of any party, breaches or threatens a breach of the provisions of this Section 5, the non-breaching party shall be entitled to seek an injunction in any court of competent jurisdiction restraining the breaching party from violating the provisions without the necessity of posting a bond or other security therefore. Nothing herein shall be construed as prohibiting the non-breaching party from pursuing any other remedies available to it at law or in equity.

5.2                               Excluded Information.  Notwithstanding anything in this Agreement to the contrary, Supplier Confidential Information and Customer Confidential Information shall not be deemed to include information that any party can demonstrate: (a) was in the public domain before the time of its disclosure by any party; (b) entered the public domain before the time of its disclosure by any party through means other than an unauthorized disclosure resulting from an act or omission by the disclosing party; (c) is independently developed by any party without use of Supplier Confidential Information or

6.3                               Remedy for Force Majeure.  The cause of the Force Majeure shall so far as possible be remedied with all reasonable dispatch. If any Force Majeure prevails for a continuous period in excess of fourteen (14) days, both Parties’ performance hereunder shall be suspended and Customer and Supplier shall enter into good faith discussions with a view to alleviating its effects, or agreeing upon alternative arrangements.
