rights and remedies hereunder with respect to any Collateral.  Without

legend in form and substance satisfactory to Secured Party, indicating that
such chattel paper is subject to the security interest granted hereby; (ii)

other reasonable and sound business practices, including a record of all
payments received and any credits granted on any of the Accounts, and
Secured Party shall have the right to inspect and copy such  records and to
inspect the Collateral at reasonable times.  Without  limiting the

through its authorized representatives, to conduct periodic field  audits

receivable methods and controls, and other matters relating to the  value
and maintenance of the Collateral and Debtor's financial reporting,  and
(ii) afford any authorized representative of Secured Party with access  to
any Property owned by Debtor, during business hours and upon reasonable
notice.  For the further security of Secured Party, Secured Party shall

taken such steps as Secured Party may deem necessary or advisable to
continue the perfection and priority of the security interest granted
pursuant hereto.

locations listed on Schedule II or, with the prior written consent of 
Secured Party, at such other location in a jurisdiction in which all
actions required by Subsection 4.2 shall have been taken with respect to
the Collateral as Debtor may have advised Secured Party at least thirty
(30) days prior to such removal.

4.6  Debtor Remains Liable.  Debtor shall remain liable under all
contracts or other agreements included in the Collateral to the extent set
forth therein to perform all of its duties and obligations thereunder to
the same extent as if this Agreement had not been executed.  The exercise
by Secured Party of any of the rights hereunder shall not release Debtor
from any of its duties or obligations under such contracts or agreements
included in the Collateral.  Secured Party shall not have any obligation or
liability under such contracts or agreements included in the Collateral by
reason of this Agreement, nor shall Secured Party be obligated to perform
any of the obligations or duties of Debtor thereunder or to take any action
to collect or enforce any claim for payment assigned hereunder.  Debtor
shall at its expense perform and observe all of the terms and provisions of
such contracts to be performed or observed by it to maintain such contracts
in full force and effect, enforce such contracts in accordance with their
terms, and take all such action to such ends as may from time to time be
reasonably requested by Secured Party.

being contested in good faith and by proper proceedings, (ii)  proper
reserves are being maintained in connection therewith, in accordance with
generally accepted accounting principles, consistently applied, and  (iii)
the proceedings referred to in clause (i) above could not subject  Secured
Party to any civil or criminal penalty or liability or involve any  risk of
sale, forfeiture or loss of any of the Collateral.

4.8  Transfers and Other Liens.  Debtor shall not: (a) sell,  assign, or
otherwise dispose of or grant any option with respect to any of the

Credit Agreement).

waive any provision of any agreement giving rise to an Account in any
manner which could reasonably be expected to materially adversely affect
the value of such Account as Collateral, or (ii) fail to exercise promptly
and diligently each and every material right which it may have under each
agreement giving rise to an Account (other than any right of termination).
Debtor will deliver to Secured Party a copy of each material demand,
notice or document sent or received by it relating in any way to any
amendment, modification, termination or waiver of any provision of any
agreement giving rise to an Account.

4.10 Secured Party's Rights and Duties.  Debtor shall remain liable under
the Accounts to observe and perform all the conditions and obligations to
be observed and performed by it thereunder, all in accordance with and
pursuant to the terms and provisions of each Account.  Secured Party shall
not have any obligation or liability under any Accounts by reason of or
arising out of this Agreement, or the receipt by Secured  Party of any
payment relating to any Account pursuant hereto, nor shall Secured Party
be required or obligated in any manner to perform or fulfill any of the
obligations of Debtor under or pursuant to any Account or to  make any
payment, or to make any inquiry as to the nature or the sufficiency of any
payment received by Secured Party or the sufficiency of any performance by
any party under any Account or to present or file any claim, or to take
any action to collect or enforce any performance or the payment of any
amounts which have been assigned to Secured Party or to which Secured
Party may be entitled at any time or times.

4.11 Collection of Accounts and Proceeds.  Debtor shall cause all payments
from account debtors on any of the Accounts to be remitted directly to a
"lockbox" maintained with Secured Party.  Until further  notice from
Secured Party, any proceeds of Accounts remitted to the lockbox, whether
consisting of checks, notes, drafts, bills of exchange, money orders,
commercial paper of any kind whatsoever, or other documents received in
payment of any Accounts or in payment for any Inventory, shall  be
deposited by Secured Party in an operating account maintained by Matrix 
with Secured Party (subject to Secured Party's established policies on 
availability of uncollected funds).  Such proceeds when deposited shall 
continue to be collateral security for all of the Indebtedness and shall 
not constitute payment thereof until applied as hereinafter provided.  Upon
the occurrence and during the continuation of an Event of Default, Secured
Party may apply all or any part of the funds on deposit in said operating
account on account of the principal of and/or interest on any of the
Indebtedness, the order and method of any such application to be in the
sole discretion of Secured Party.  If an Event of Default shall have
occurred and be continuing, at Secured Party's request Debtor shall deliver
to Secured Party all original and other documents evidencing and relating
to the sale and delivery of Inventory or the performance of labor or
services which created the Accounts, including, but not limited to, all 
original orders, invoices, and shipping receipts.  Secured Party may, at 
any time after the occurrence and during the continuation of any Event of 
Default, notify account debtors that the Accounts have been assigned to 
Secured Party and that payment shall be made directly to Secured Party, and
Debtor will so notify such account debtors on the request of Secured Party.
 Secured Party may in its own name or in the name of others, at any time
after the occurrence and during the continuation of any Event of Default,
communicate with account debtors in order to verify with them the existence,
amount, and terms of any Accounts.

the occurrence of an "Event of Default" as defined in the Credit Agreement.

Default, Secured Party may, at its option, without notice or demand,

defined in the Credit Agreement) and declare the Indebtedness to be
immediately due and payable, whereupon the same shall become forthwith due
and payable.

6.2  Other Remedies.  Upon the occurrence and during the continuation of
any Event of Default, Secured Party shall be entitled to exercise all
remedies available to it under the Loan Documents (as defined in the
Credit Agreement) or otherwise under applicable law, including, without
limitation, the following:

6.2.1All Legal Remedies.  Proceed to selectively and successively enforce
and exercise any and all rights and remedies which Secured Party may have
under this Agreement, any other applicable agreement or applicable law,
including, without limitation:  (i) commencing one or more actions against
Debtor and reducing the  claims of Secured Party against Debtor to judgment,
(ii) foreclosing,  realizing upon, or otherwise enforcing Secured Party's
security  interest in the Collateral, or any portion thereof, or other
enforcing  Secured Party's rights and remedies in respect of the Collateral,
through judicial action or otherwise, including all available remedies  under
the applicable provisions of the UCC, and (iii) paying or  discharging of any
claim or Lien, prior or subordinate, in respect of  or affecting the
Collateral.

6.2.2Cash Equivalent Items.  As regards any portion of the Collateral
consisting of cash equivalent items (i.e., checks, drafts or other items
convertible at face), immediately apply them  against the Indebtedness and
for this purpose Debtor agrees that such  items will be considered identical
in character to cash proceeds.

6.2.3Disposition.  Sell, lease or otherwise dispose of the Collateral at
private or public sale, in bulk or in parcels and, where permitted by law,
without having the Collateral present at the place of sale.  Unless the
Collateral is perishable or it appears that the value of the Collateral
will decline speedily or the Collateral is a type customarily sold on a
recognized market, or unless Debtor has  signed a statement (after the
occurrence of an Event of Default)  renouncing or modifying Debtor's right
to notice, Secured Party will  give Debtor reasonable notice of the time
and place of any public sale or other disposition thereof or the time
after which any private sale or other disposition thereof is to be made.
The requirements of  reasonable notice shall be met if such notice is given
to Debtor at least ten (10)days before the time of any such sale or
disposition.

6.2.4Costs and Expenses.  Recover from Debtor an amount equal to all costs,
expenses and attorney's fees incurred by Secured  Party in connection with
the exercise of the rights contained or  referred to herein, together with
interest on such sums at the default  rate applicable to the Term Note from
time to time.

6.2.5Collections.  Exercise any and all rights and remedies of Debtor
relating to the Collateral, including, but not by way of limitation, the
right to collect, demand, receive, settle, compromise, adjust or sue for
all amounts due thereon or thereunder  and the right either in Secured
Party's own name or in the name of  Debtor, to take such legal or other
action as Debtor might have taken  except for this Agreement.

6.3  Letters of Credit.  Upon the acceleration of the Indebtedness after
an Event of Default an amount equal to the aggregate stated amount of all
outstanding Letters of Credit issued by Secured Partyfor the account of
the Borrowers shall, at Secured Party's option and without demand upon or
further notice to Debtor, be deemed (as between Secured Party and the
Borrowers) to have been paid or disbursed by Secured Party under the Letters
of Credit (notwithstanding that such amounts may not in fact have been so
paid or disbursed), and a loan to the Borrowers in the amount of such Letters
of Credit to have been made and accepted, which loan shall be immediately
due and payable and shall bear interest at the post default rate provided in
the Revolving Note.  In lieu of the foregoing, at the election of Secured
Party, Debtor and/or the other Borrowers shall, upon Secured Party's demand,
deliver to Secured Party cash, or other collateral of a type satisfactory to
Secured Party, having a value, as determined by Secured Party, equal to the
aggregate outstanding Letters of Credit.  Any such collateral and/or any
amounts received by Secured Party in payment of the loan made pursuant to
this Section shall be held by Secured Party in a separate account
appropriately designated as a cash collateral account in relation to this
Agreement and the Letters of Credit and retained by Secured Party as
collateral security for the Indebtedness and each of the Letters of Credit.
Such amounts shall not be used by Secured Party to pay any amounts drawn or
paid under or pursuant to any Letter of Credit, but may be applied to
reimburse Secured Party for drawings or payments under or pursuant to Letters
 of Credit which Secured Party has paid or, if no such reimbursement is
 required, to payment of suchother Indebtedness as Secured Party shall
 determine.  At the option ofSecured Party, proceeds of sale of the
 Collateral may be used to fund thecash collateral account herein provided
 for.  Any amounts remaining in any cash collateral account established
 pursuant to this Section following payment in full of the Indebtedness,
 which amounts are not (as determined by Secured Party) to be applied to
 reimburse Secured Party for amounts actually paid by Secured Party in
 respect of a Letter of Credit, shall be returned to the Borrowers (after
 deduction of Secured Party's reasonable and necessary expenses).

6.4  Selective Enforcement.  In the event Secured Party shall elect to
selectively and successively enforce its rights and remedies in respect of
any of the Collateral, pursuant to any applicable agreements or otherwise,
such action shall not be deemed a waiver or discharge of any other right,
remedy, lien or encumbrance until such time as Secured Party shall have
been paid in full the Indebtedness.

6.5  Waiver of Default.  Secured Party may, by an instrument in writing
signed by Secured Party, waive any Event of Default which shall have
occurred and any of the consequences thereof and, in such event, Secured
Party and Debtor shall be restored to their respective former positions,
rights and obligations.  Any Event of Default so waived shall, for all
purposes of this Agreement, be deemed to have been cured and not to be
continuing, but no such waiver shall extend to any subsequent or other 
default or impair any consequence thereof.

6.6  Deposits; Setoff.  Regardless of the adequacy of any other Collateral
held by Secured Party, any deposits or other sums credited by or due from
Secured Party to Debtor shall at all times constitute collateral security
for the Indebtedness and may be set off against the Indebtedness. The
rights granted in this subsection shall be in addition to the rights of
Secured Party under any statutory banker's lien or common law right of
setoff.

6.7  Application of Payments.  During the continuance of any  Event of
Default, all payments received by Secured Party in respect of the 
Indebtedness, whether from Debtor, any of the other Borrowers, any 
guarantor, recoveries upon any portion of the Collateral or otherwise, may
be applied by Secured Party to any liabilities, obligations or indebtedness
included in the Indebtedness selected by Secured Party in its sole and
exclusive discretion.

6.8  Secured Party's Satisfaction of Debtor's Obligations.  Upon the
occurrence of any event which, but for the giving of notice or the passage
of time, would constitute an Event of Default, Secured Party may, but
shall not be obligated to, pay, satisfy or cure any liability or
obligation of Debtor arising out of or relating to this Agreement or the
Notes, upon prior notice to Debtor, and Debtor will from time to time
within ten (10) days after a request made by Secured Party, reimburse
Secured Party for all amounts expended, advanced or incurred by Secured
Party in connection with such payment, cure or satisfaction, together with
interest on such sums at the default rate applicable to the Term Note from
time to time.
