becomes publicly available without default hereunder by the receiving party;



(b) is lawfully acquired by the receiving party from a third party not under any obligation of confidentiality to the disclosing party with respect to such information;

form of any court or other governmental authority, or by oral questions, interrogatories, requests for information or documents or by any court or other governmental authority or other person in legal proceedings, subpoenas, civil investigative
demands or other similar processes) to disclose any of the Confidential Information received from the other party, the receiving party so requested or required, or whose representative has been so requested or required, shall provide the other party

representative may, without liability hereunder, disclose to such tribunal only that portion of the Confidential Information which is legally required to be disclosed.

the receiving party shall return all the Confidential Information including all copies, or shall certify in writing that all such Confidential Information and copies have been destroyed.

arbitrator panel determines. Judgment upon that decision or award may be entered in any court having jurisdiction over either or both of the parties or their respective assets, and the enforcement of that decision or award will be in accordance with
