documents and instruments referred to therein or at any time executed and/or
delivered in connection therewith or related thereto, including this Amendment
(all of the foregoing, including the Credit Agreement, as the same now exists or
may hereafter be further amended, modified, supplemented, extended, renewed,

      WHEREAS, Borrowers have requested that Lender agree to certain amendments

      NOW, THEREFORE, in consideration of the mutual conditions and agreements

agree as follows:

      Section 1. INTERPRETATION. For purposes of this Amendment, all terms used

      "12.19  CONFIDENTIALITY.
<PAGE>

            (a) Lender shall use all reasonable efforts to keep confidential, in
      accordance with its customary procedures for handling confidential
      information and safe and sound lending practices, any non-public
      information supplied to it by Borrowers or Borrowers' accountants or
      attorneys pursuant to this Agreement or prior to the date of this
      Agreement in connection with Lender's credit evaluation of Borrowers, in
      any case which is clearly confidential by its nature or which is clearly
      and conspicuously marked as confidential at the time such information is
      furnished by Borrowers to Lender, PROVIDED, THAT, nothing contained herein
      shall limit the disclosure of any such information: (i) to the extent
      required by statute, rule, regulation, subpoena or court order, (ii) to
      bank examiners and other regulators, auditors and/or accountants, (iii) in
      connection with any litigation to which Lender is a party, (iv) to any
      assignee or participant (or prospective assignee or participant) so long
      as such assignee or participant (or prospective assignee or participant)
      shall have first agreed in writing to treat such information as
      confidential in accordance with this Section 12.19, or (v) to counsel for
      Lender or any participant or assignee (or prospective participant or
      assignee).

            (b) In no event shall this Section 12.19 or any other provision of
      this Agreement or applicable law be deemed: (i) to apply to or restrict
      disclosure of information that has been or is made public by Borrowers or
      any third party without breach of this Section 12.19 or otherwise become
      generally available to the public other than as a result of a disclosure
      in violation hereof, (ii) to apply to or restrict disclosure of
      information that was or becomes available to Lender on a non-confidential
      basis from a person other than Borrowers, (iii) to require Lender to
      return any materials furnished by Borrowers to Lender or (iv) to prevent
      Lender from responding to routine informational requests in accordance
      with the CODE OF ETHICS FOR THE EXCHANGE OF CREDIT INFORMATION promulgated
      by The Robert Morris Associates or other applicable industry standards
      relating to the exchange of credit information. The obligations of Lender
      under this Section 12.19 shall supersede and replace the obligations of
      Lender under any confidentiality letter signed prior to the date hereof."

      Section 3. CONDITIONS PRECEDENT. The effectiveness of the amendment
contained herein shall be subject to Lender's receipt of an original of this
Amendment, in form and substance satisfactory to Lender, duly authorized,
executed and delivered by Borrowers and the execution of this Amendment by
