authorities to change the address for delivery of such Borrower's, EPSC's or
ADI's mail to an address designated by Lender, and to receive, open and dispose
of all mail addressed to such Borrower. Each Borrower, EPSC and ADI hereby
ratifies and approves all acts of the attorney. Neither Lender nor the attorney
will be liable for any acts or omissions or for any error of judgment or mistake
of fact or law. This power, being coupled with an interest, is irrevocable so
long as any Receivable which is assigned to Lender or in which Lender has a
security interest remains unpaid and until the Obligations have been fully
satisfied."

     (l)  Paragraph 19 is amended in its entirety to provide as follows:

          "19. Remedies.  Upon the occurrence of an Event of Default pursuant
to paragraph 18(k) herein, all Obligations shall be immediately due and
payable and this Agreement shall be deemed terminated; upon the occurrence and
continuation of any other of the Events of Default, Lender shall have the right
to demand repayment in full of all Obligations, whether or not otherwise due.
Until all Obligations have been fully satisfied, Lender shall retain its
security interest in all Collateral. Lender shall have, in addition to all other
rights provided herein, the rights and remedies of a secured party under the
UCC, and under other applicable law, all other legal and equitable rights to
which Lender may be entitled, including without limitation, the right to take
immediate possession of the Collateral, to require Borrowers, EPSC and ADI to
assemble the Collateral, at Borrowers', EPSC's or ADI's expense, and to make it
available to Lender at a place designated by Lender which is reasonably
convenient to both parties and to enter any of the premises of any Borrower,
EPSC or ADI or wherever the Collateral shall be located, with or without force
or process of law, and to keep and store the same on said premises until sold
(and if said premises be the property of a Borrower, EPSC or ADI, such Borrower,
EPSC and ADI agrees not to charge Lender for storage thereof), and the right to
apply for the appointment of a receiver for any Borrower's, EPSC's or ADI's
property. Further, Lender may, at any time or times after default by any
Borrower, EPSC or ADI sell and deliver all Collateral held by or for Lender at
public or private sale for cash, upon credit or otherwise, at such prices and
upon such terms as Lender, in Lender's sole discretion, deems advisable or
Lender may otherwise recover upon the Collateral in any commercially reasonable
manner as Lender, in its sole discretion, deems advisable. The requirement of
reasonable notice shall be met if such notice is mailed postage prepaid to
Borrowing Agent's address as shown in Lender's records, at least ten (10) days
before the time of the event of which notice is being given. Lender may be the
purchaser at any sale, if it is public. In connection with the exercise of the
foregoing remedies, Lender is granted permission to use all of Borrowers'
trademarks, tradenames, tradestyles, patents, patent applications, licenses,
franchises and other proprietary rights which are used in connection with

                                       10

(a) Inventory for the purpose of disposing of such Inventory and (b)
Equipment for the purpose of completing the manufacture of unfinished goods. The
proceeds of sale shall be applied first to all costs and expenses of sale,
including attorneys' fees, and second to the payment (in whatever order Lender
elects) of all Obligations. Lender will return any excess to Borrowers and
Borrowers shall remain liable to Lender for any deficiency. In addition to all
other sums due to Lender, Borrowers shall pay Lender, for costs and expenses
incurred by Lender for internal collection efforts to obtain or enforce payment
of Receivables and the ADC Receivables, an amount equal to fifteen percent (15%)
of the net face amount of any Receivables and ADC Receivables collected."

     (m)  Paragraph 25 is amended to include the following at the end thereof:

          "If to ADI: To Borrowing Agent as set forth above."

          If to EPSC: To Borrowing Agent as set forth above."
