The Parties commit to instruct their respective counsel to cooperate with each other and use commercially reasonable efforts to facilitate and expedite the identification and resolution of any issues arising under the Competition Laws at the earliest practicable dates. Such commercially reasonable efforts and cooperation include counsel’s undertaking # to keep each other appropriately informed of communications from and to personnel of the reviewing Governmental Authorities and # to confer with each other regarding appropriate contacts with and response to personnel of such Governmental Authorities and the content of any such contacts or presentations. Neither Sellers nor Purchaser will participate in any meeting or discussion with any Governmental Authority with respect of any such filings, applications, investigation or other inquiry without giving the other Parties prior notice of the meeting or discussion and, to the extent permitted by the relevant Governmental Authorities, the opportunity to attend and participate in such meeting or discussion (which, at the request of either Purchaser or Sellers, will be limited to outside antitrust counsel only). Purchaser and Sellers will have the right to review (subject to appropriate redactions for confidentiality and attorney-client privilege concerns) the content of any presentations, white papers or other written materials to be submitted to any Governmental Authority in advance of any such submission. Notwithstanding the foregoing, any Party may, as it deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other Parties under this Section 6.1(c) as “outside counsel only.” Such materials and the information contained therein shall be given only to the outside counsel of the recipient Party, and the recipient Party shall cause such outside counsel not to disclose such materials or information to any employees, officers, directors or other representatives of the recipient Party, unless express written permission is obtained in advance from the source of the materials.
