any shareholder, officer, director or partner of any entity that signs this
Settlement Agreement or the Mutual General Release, or to any individual who was
deposed in any capacity in the Civil



                                      -7-

 
Action; (ii) any Settlement Agreement Party may disclose this Settlement

be required under a lawful order of any court or governmental agency, or
otherwise specifically required by law, regulation or other controlling legal
requirement, the Settlement Agreement Party wishing to make such disclosure
shall provide reasonable advance notice to each other Settlement Agreement Party
of its intention to disclose in order to enable the other Settlement Agreement
Parties, if they so desire, to seek to prevent



                                      -8-

 
such disclosure by appropriate legal means.  Such notice need not be given to
each individual entity or individual that is a member of any of the Settlement

shall be construed to have any effect on (i) Boyle's rights, if any, to
indemnification from the Plaintiffs for any claims made against Boyle arising
out of conduct prior to the execution of this Settlement Agreement; or (ii) any
invoices from D. Quinn Mills to Boyle for services rendered as a mediator in the
Civil Action, or on the obligations, if any, of Boyle to make any payment with
