Information which it is advised by opinion of its counsel is legally required to
be furnished and shall exercise all commercially reasonable efforts to obtain
reliable assurance that confidential treatment shall be accorded such
Confidential Information, it being understood that such reasonable efforts shall
be at the cost and expense of the disclosing party whose Confidential
Information has been sought.

          to perform its obligations under this agreement or to have a material
          adverse effect on the consolidated financial condition of each party
          or its Parent.

          or before or by any governmental department, board, agency or
          instrumentality, domestic or foreign, or any arbitrator which could,
          if adversely determined (or, in the case of an investigation could
          lead to any action, suit or proceeding, which if adversely determined
          could), reasonably be expected to materially impair such party's
          ability to perform its obligations under this agreement or to have a
          material adverse effect on the consolidated financial condition of
          such party or its parent; and such party or any of its Controlled
          Related Parties has not received any currently effective notice of any
          default, and such party or any of its Controlled Related Parties is
