                  CROSS-COLLATERAL AND CROSS-DEFAULT AGREEMENT

Caterpillar Financial Corporation

Gentlemen:

You have purchased one or more  conditional  sales contracts or lease agreements
(herein designated "Accounts"), arising from the bona fide sale, or lease to us,
by various  vendors or lessors of equipment  and  inventory  (herein  designated
"Collateral"),  and/or  you have made  direct  loans to, or  otherwise  extended
credit, to us evidenced Accounts creating security interests in Collateral.

In order to induce you to extend  our time of  payment on one or more  Accounts,
and/or to make additional loans to us, and/or to purchase  additional  Accounts,
and   inconsideration  of  you  so  doing,  and  for  other  good  and  valuable
consideration, the receipt of which we hereby acknowledge, we agree as follows:

All presently  existing and hereafter  acquired  Collateral in which you have or
shall have a security interest,  shall secure the payment and performance of all
of our liabilities and obligations to you, of every kind and character,  whether
joint or several, direct or indirect,  absolute or contingent,  due or to become
due,  and whether  under  presently  existing or hereafter  created  Accounts or
agreements, or otherwise.

We further  agree that your  security  interesting  the  property  covered by an
Account now held,  or hereafter  acquired by you,  shall not be  terminated,  in
whole or in part,  until and unless all  indebtedness  of every kind,  due or to
become  due,  owed by us to you are to  retain  your  security  interest  in all
property  covered by all  Accounts  held or acquired  by you,  as  security  for
payment and performance under each such Account,  notwithstanding  the fact that
one or more of such Accounts may become fully paid.

This instrument is intended to create  cross-default and cross-security  between
and among all the within described Accounts now owned, or hereafter acquired, by
you.

A default  under any Account or agreement  shall be deemed to be a default under
all other Accounts and agreements.  A default shall result if we fail to pay any
sum when due, on any Account or agreement, or if we beach any of the other terms
and conditions  thereof,  or if we became  insolvent,  cease to do business as a
going concern, make an assignment for the benefit of creditors, or if a petition
for a receiver  or if  bankruptcy  is filed by or  against  us, or if any of our
property  is seized,  attached  or levied  upon.  Upon our  default,  any or all
Accounts and  agreements  shall,  at your  option,  become  immediately  due and
payable,  without notice or demand to us or any other party  obligated  thereon,
and you shall  have,,  and may  exercise  any and all rights and  remedies  of a
secured party under the Uniform  Commercial  Code, as enacted in the  applicable
jurisdiction  and as  otherwise  granted  to you  under  any  Account  or  other
agreement.  We hereby waive, to the maximum extent  permitted by law, notices of
default,  notices of repossession  and sale or other  disposition of Collateral,
and all other  notices,  and in the event any such notice can not be waived,  we
agree that if such notice is mailed to us, postage prepaid, to

shall be in addition to and shall in no manner  impair or affect your rights and
remedies under any existing Account, agreement, statute or rule of law.

This Agreement shall be governed by and construed under the laws of the State of
Tennessee, without giving effect to the conflict-of-laws principles thereof, and
we hereby  consent to the  jurisdiction  of any state or federal  court  located
