<PAGE>

     (a) No Other Encumbrances. Except for the security interests granted by
this Agreement and subordinate security interests granted as part of Borrower's
present lending arrangements on the assets of Borrower, Borrower is the sole
owner of the Collateral free and clear of all liens, claims and encumbrances.

     (b) Location of Collateral. The Collateral shall be located at the
Borrower's Morehouse-COWLES Division's place of business in Fullerton,
California. Borrower will not change the location of the Collateral or cause
such Collateral to be moved, maintained or stored in any other location without
notifying the Secured Party. In no event without the prior written consent of
the Secured Party shall the collateral be shipped to a location outside the
United States unless such shipment is part of the sale of the Collateral.

                              ARTICLE 4 COVENANTS

     Section 4.01 The Borrower covenants and agrees with the Secured Party that:

     (a) Inspection of Collateral. The Secured Party or its agents may at any
time and from time to time inspect the Collateral and the books and records of
the Borrower pertaining thereto upon reasonable notice to Borrower and during
regular business hours.

     (b) Expenses. Borrower shall be liable for and agree to pay the Secured
Party any and all expenses incurred or paid by the Secured Party in protecting
or enforcing its rights under this Agreement including reasonable attorneys'
fees and legal expenses.

     (c) Application of Net Proceeds. Upon an Event of Default, the Secured
Party shall have the right to apply the net proceeds of the sale or other
disposition of the Collateral, first, to the principal indebtedness due under
the Note and then to any other indebtedness of the Borrower owed to the Secured
Party.

     (d) Maintenance of Collateral. Borrower will keep all Collateral in good
condition and repair at Borrower's own expense. Any loss or destruction of the
Equipment shall be at Borrower's risk and shall not release Borrower from any
Obligation set forth herein.

     Section 4.02 Insurance. Borrower agrees at its expense to insure its
respective Collateral against such risks and hazards. Borrower will use
reasonable efforts to have its policy of insurance contain a clause that in the
event of loss, payments shall be made to the Secured Party as its interest may
appear; that Borrower hereby grants the Secured Party a security interest in the
proceeds of any insurance, whether paid by reason of loss, injury, return
premium or otherwise, and such proceeds may be applied toward the repair or
replacement of the Collateral or payment of the Obligations secured hereby at
Borrower's option.

     Section 4.03 Proceeds from Resale of Collateral. Borrower agrees that all
Net Proceeds (as hereinafter defined) from the sale of the Collateral, or any
part of it, shall be paid as herein provided to the Secured Party as provided in
Section 4.04, it being expressly understood and agreed by the parties that, in
the event a case under the United States Bankruptcy Code is commenced by or
against Borrower, the Net Proceeds (meaning the proceeds from the sale of any of
the collateral, less reasonable transportation costs, storage and reconditioning
costs, and costs of sale including but not limited to commissions and taxes
attributable to the sale of such


                                       2
<PAGE>

collateral) shall not constitute property of Borrower's bankruptcy estate, but
shall belong to Secured Party.

     Section 4.04 Sale and Sale Notice of Collateral. In the event Borrower
sells the Collateral, or any part of it, prior to the satisfaction of the Note,
Borrower shall promptly give notice of the sale to the Secured Party three (3)
business days before Borrower is required to ship the collateral to any buyer.
Prior to the scheduled date for shipping, the Secured Party shall release its
security interest in the portion of the Collateral sold by Borrower. For
purposes of releasing its security therein upon a sale of the Collateral, the
Secured Party hereby appoints the Borrower through any officer designated by the
Borrower, as attorney-in-fact for the Secured Party, with power to act in
Secured Party's name with respect to the release of the Secured Party's security
interest. Within ten (10) business days following such sale(s), the Borrower
shall provide notice ("Sale Notice") of the Net Proceeds to be received from
such sale(s) to Secured Party. Such Sale Notice(s) shall contain: (a) a detailed
description of the sales terms, including, without limitation, a description of
the Collateral being sold, the price received, and a statement setting forth
what portion, if any, of the Collateral remains unsold; (b) a detailed statement
of the following costs actually incurred by Borrower in connection with such
sale(s) (the "Sales Costs"): (i) all transportation costs incurred by Borrower
to ship the Collateral sold from Secured Party's location to Borrower's
Morehouse-COWLES Division in Fullerton, California; (ii) reasonable storage and
reconditioning costs incurred by Borrower as to the Collateral sold; and (iii)
costs related to the sale of the Collateral sold, including but not limited to
commissions and taxes actually incurred and paid by Borrower; and (c) a
statement of the Net Proceeds, calculated by subtracting the Sales Costs from
the price received in the sale. Borrower shall direct the purchaser(s) of the
Collateral, or any part of it, to pay an amount equal to the Net Proceeds from
each sale of Collateral directly to the Secured Party.

                          ARTICLE 5 EVENTS OF DEFAULT

federal Bankruptcy Code or any other federal or state bankruptcy, insolvency or
other similar law or regulation, and such proceeding or case is not dismissed or
stayed within 60 days of filing.

                               ARTICLE 6 REMEDIES

     Section 6.01 If the Borrower fails to make a payment on the Note when due
or if any of the Events of Default specified herein shall occur, and Borrower
fails to cure the Event of Default within thirty (30) days from the date of
written notice from the Secured Party in the event of a non-payment Event of
Default, or three (3) business days in the event of a payment Event of Default,
then in such event and at any time thereafter the Secured Party may declare all
Obligations secured hereby to be immediately due and payable without
presentment, demand, protest, or other notice of any kind, all of which are
hereby expressly waived. The Secured Party in addition to such other rights and
remedies as are or may be set forth in this Agreement and in any other agreement
between the parties or any Obligation secured hereby or thereby may exercise and
shall have the rights and remedies of a Secured Party under the Uniform
Commercial Code in effect in the State of Georgia at the date of this Agreement.
The Secured Party may require and Borrower agrees upon demand to assemble the
Collateral and make it available at a place to be designated by the Secured
Party which is reasonably convenient to the parties or the Secured Party may
enter any premises and take possession of the Collateral or any part thereof.
Unless the Collateral is perishable or threatens to decline speedily in value or
is of a type customarily sold on a recognized market, the Secured Party will
give Borrower reasonable notice of time and place of any public sale thereof or
the time after which any private sale or any other intended disposition thereof
is to be made. The requirement of reasonable notice shall be met if notice is
mailed, postage prepaid to Borrower at its above mentioned address, at least ten

the Secured Party in protecting or enforcing its rights, powers and remedies
hereunder or under any other agreement between the parties or any Obligation
secured hereby or thereby or in any way connected with any proceeding or action
by whatsoever initiated concerning the protection or enforcement thereof.

     Section 6.02 No delay in taking any action with respect to any Event of
Default shall affect the rights of the Secured Party later to take such action
with respect thereto and no waiver by the Secured Party of any default shall
operate as a waiver of any other default, or the same default on a future
occasion.
