to materially adversely affect the assets, business or any activity of the
Borrower and the Guarantors as a whole, and (iv) do not conflict with any
provision of the corporate charter or bylaws of the Borrower or any Guarantor
or any agreement or other instrument binding upon the Borrower or any
Guarantor.

    (b)      The execution, delivery and performance of this Second Amendment
and the Credit Agreement, as modified by this Second Amendment, will result in
valid and legally binding obligations of the Borrower and the Guarantors party
thereto enforceable against each in accordance with the respective terms and
provisions hereof and thereof, except as enforceability is limited by
bankruptcy, insolvency, reorganization, moratorium or other laws relating to or
affecting generally the enforcement of creditors rights and except to the
extent that availability of the remedy of specific performance or injunctive
relief is subject to the discretion of the court before which any proceeding
therefor may be brought.

    (c)      The execution, delivery and performance by the Borrower and the
Guarantors of this Second Amendment and the Credit Agreement, as modified by
this Second Amendment, and the consummation by the Borrower and the Guarantors

or consent of, or filing with, any governmental agency or authority other than
those already obtained and those required after the date hereof in connection
with the Borrower's and the Guarantors' performance of their covenants
contained in Sections 7, 8 and 9 of the Credit Agreement.

    (d)      The representations and warranties contained in Section 6 of the
Credit Agreement are true and correct in all material respects as of the date
hereof as though made on and as of the date hereof.

the Guarantors hereby confirms that its guaranty of the Guaranteed Obligations
contained in Section 27 of the Credit Agreement remains in full force and
effect.  This Second Amendment and the Credit Agreement shall hereafter be read
and construed together as a single document, and all references in the Credit
Agreement, any other Loan Document or any agreement or instrument related to
the Credit Agreement shall hereafter refer to the Credit Agreement as amended
by this Second Amendment.
