(“ATN”), including, without limitation, information regarding the Services, potential acquisitions, investment opportunities, the Company’s billing and other systems, or the Company’s finances, plans, marketing, customers, vendors, products, technology, research and know how, in addition to information regarding other companies or persons (a “Third Party”) which the Consultant may have received from the Company, ATN or directly from such Third Party, and which has been designated as confidential information or would reasonably be considered confidential based on the nature of the information and the circumstances of the disclosure (collectively, the “Confidential Information”).

4.2           Consultant will hold the Confidential Information in confidence and protect it in accordance with the security measures by which he protects his own proprietary and/or Confidential Information of similar kind, provided that Consultant will use at least a reasonable degree of care.

4.3           If Consultant or any of his Representatives become legally compelled by law, regulation, rule, or by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process, or is advised by legal counsel to disclose any of the Confidential Information, Consultant will use reasonable efforts to provide the Company with prompt notice of such requirement or advice prior to disclosure so that the Company or Third Party, as the case may be, may seek a protective order or other appropriate remedy and/or waive compliance with the terms of this Agreement. If such protective order or other remedy is not obtained prior to the date that the Consultant or his Representative is compelled to disclose any of the Confidential Information, or the Company or such Third Party waives compliance with the provisions hereof, the Consultant or his Representative will furnish only that portion of the Confidential Information which he is legally required to so furnish and use reasonable efforts to obtain assurance that confidential treatment will be accorded such Confidential Information. Notwithstanding anything herein to the contrary, nothing in this agreement shall (i) prohibit the consultant from making reports of possible violations of federal law or regulation to any governmental agency or entity in accordance with the provisions of and rules promulgated under Section 21F of the United States Securities Exchange Act of 1934 or Section 806 of the United States Sarbanes-Oxley Act of 2002, or of any other whistleblower protection provisions of local, state or federal law or regulation, or (ii) require notification or prior approval by the Company of any reporting described in clause (i).

4.4           Upon the Company’s request or in any event upon completion of the Services, Consultant will return to the Company all notes, data, documents, media and other items containing, or relating in any way to the Confidential Information or the Results (as defined below) and any copies in Consultant’s possession or control.
