         the Borrowers and constitutes the legal, valid and binding obligation

         affecting creditor's rights generally and by general equitable
         principles.

                                       -3-

         authorization, consent or approval by any governmental department,
         commission, board, bureau, agency or instrumentality, domestic or
         foreign, (ii) violate any provision of any law, rule or regulation or
         of any order, writ, injunction or decree presently in effect, having
         applicability to the Borrowers, or the articles of incorporation or

                  (c) All of the representations and warranties contained in
         Article V of the Credit Agreement are correct in all material respects
         on and as of the date hereof as though made on and as of such date,
         except to the extent that such representations and warranties relate
         solely to an earlier date.

                  7. REFERENCES. All references in the Credit Agreement to "this
Agreement" shall be deemed to refer to the Credit Agreement as amended hereby;

                  8. NO OTHER WAIVER. Except as set forth in Paragraph 5 hereof,

Credit Agreement or breach, default or event of default under any Security
Document or other document held by the Lender, whether or not known to the
Lender and whether or not existing on the date of this Amendment.

                  9. RELEASE. The Borrowers hereby absolutely and

participants, parent corporations, subsidiary corporations, affiliated
corporations, insurers, indemnitors, successors and assigns thereof, together

any of the foregoing, from any and all claims, demands or causes of action of
any kind, nature or description, whether arising in law or equity or upon
contract or tort or under any state or federal law or otherwise, which the
Borrowers have had, now have or have made claim to have against any such person
for or by reason of any act, omission, matter, cause or thing whatsoever arising
from the beginning of time to and including the date of this Amendment, whether
such claims, demands and causes of action are matured or unmatured or known or
unknown.
