4. | In the event that either party, as a Receiving Party or any of its Representatives, receives a request, or is required, to disclose all or any part of the Confidential Information (or to make any disclosure otherwise prohibited hereby) under the terms of a subpoena, deposition, interrogatory, request for information or documents, civil investigative demand or other legal process or order issued by a court or governmental, regulatory or administrative body of competent jurisdiction or under any law, regulation, governmental proceeding or stock exchange rule, each party, as a Receiving Party, agrees to, and to cause its Representatives to, (a) to the extent permitted by the applicable law, regulation or body of competent jurisdiction, promptly notify the Disclosing Party of the existence, terms and circumstances surrounding such a request or requirement so that it may seek an appropriate protective order and/or waive the Receiving Party’s compliance with the provisions of this letter agreement (and, if the Disclosing Party seeks such an order, to provide such reasonable cooperation during normal business hours as the Disclosing Party shall reasonably request at the Disclosing Party’s sole expense) and (b) if, following the failure of the Disclosing Party to obtain such protective order, disclosure of such Confidential Information is required in the opinion of the Receiving Party’s legal counsel, exercise reasonable efforts (other than expenditure of funds) to obtain an order or other reliable assurance that confidential treatment will be accorded to such of the disclosed information which the Disclosing Party so designates. Following the failure of the Disclosing Party to obtain such protective order prior to the required disclosure, if in the opinion of the Receiving Party’s legal counsel, disclosure of such Confidential Information is required, the Receiving Party and its Representatives shall be permitted to disclose only that portion of the Confidential Information that is, in the opinion of the Receiving Party’s legal counsel, required to be disclosed. For the avoidance of doubt, it is understood and agreed that the Receiving Party shall not be deemed to be requested or required under applicable law or applicable rules or regulations of any national securities exchange to disclose any Confidential Information solely by virtue of the fact that, absent such disclosure, the Receiving Party or any person acting on its behalf or in concert with the Receiving Party may be prohibited from purchasing, selling or engaging in derivative or other voluntary transactions with respect to the securities of the Disclosing Party or that the Receiving Party may be unable to file any proxy or other solicitation materials or tender or exchange offer materials, in compliance with Section 14 of the Securities Exchange Act of 1934, as amended or the rules or regulations promulgated thereunder (the “Exchange Act”). |
