- 16 -

its representatives pursuant to this Agreement (except to the extent that such information can be shown to have been (i) previously known by the Party to which it was furnished, (ii) in the public domain through no fault of such Party, or (iii) later lawfully acquired from other sources by the Party to which it was furnished), and each Party shall not release or disclose such information to any other person, except its auditors, attorneys, financial advisors, bankers and other consultants and advisors who shall be advised of the provisions of this Agreement.
