and (ii) no Event of Default exists, (b) agree that the term "Credit
Agreement," as defined in the Security Agreement ("Security Agreement") is
redefined to mean the Credit Agreement dated as of March 31, 1995 between the
Borrowers and the Bank, as amended, restated, modified or/or supplemented
from time to time, and (c) acknowledge and agree that the security interest

respect of the Revolving Credit, as increased hereby and the Revolving Credit
Note, as amended in connection herewith.

     8.   All terms and conditions of the Credit Agreement shall remain in

waiver of any right, power or remedy of the Bank under the Credit Agreement
or any agreement or instrument related to or executed in connection therewith
(including the Guaranty Agreement dated as of April 13, 1995 executed by CMI
in favor of the Bank), nor constitute a waiver of any provision of the Credit
Agreement or any such agreement or instrument.

and substance satisfactory to the Bank, and (b) a legal opinion from counsel
to the Borrowers in form and substance satisfactory to the Bank.

     10.  This First Amendment may be executed in any number of counterparts,
all of which taken together shall constitute one and the same instrument and

counterpart.  This First Amendment shall be governed and construed in
