encumbrance or Lien and the receipt of the usual official notice for the payment

or under any other agreement between Borrower and Lender.

               (b) Lender may declare all Obligations to be due and payable
immediately, whereupon they shall immediately become due and payable without
presentment, demand, protest or notice of any kind, all of which are hereby
expressly waived by Borrower.


                                     - 16 -

   17



               (c) Lender may set off against the Obligations all Collateral,
balances, credits, deposits, accounts, or moneys of Borrower then or thereafter
held with Lender, including amounts represented by certificates of deposit.

               (d) Lender may pay, purchase, contest or compromise any
encumbrance, charge or Lien that, in the opinion of Lender, appears to be prior
or superior to its Lien and pay all reasonable expenses incurred in connection
therewith.

               (e) Lender may (i) notify Account Debtors to make payment on
Accounts directly to Lender; (ii) settle, adjust, compromise, extend or renew
Accounts, whether before or after legal proceedings to collect such Accounts
have commenced; (iii) prepare and file any bankruptcy proofs of claim or similar
documents against any Account Debtor; (iv) prepare and file any notice,
assignment, satisfaction, or release of Lien, UCC termination statement or any
similar document; (v) sell or assign Accounts, individually or in bulk, upon
such terms, for such amounts, and at such time or times as Lender deems
advisable; and (vi) complete the performance required of Borrower under any
contract or agreement to which Borrower is a party and out of which Accounts
arise or may arise.

               (f) Lender may (i) endorse Borrower's name on all checks, notes,
drafts, money orders or other forms of payment of or security for Accounts or
other Collateral; (ii) sign Borrower's name on drafts drawn on Account Debtors
or issuers of letters of credit; and (iii) notify the postal authorities in
Borrower's name to change the address for delivery of Borrower's mail to an
address designated by Lender, receive and open all mail addressed to Borrower,
copy all mail, return all mail relating to Collateral, and hold all other mail
available for pickup by Borrower.

               SECTION 11.2. POWER OF ATTORNEY Borrower hereby appoints Lender
(and any of Lender's officers, employees, or agents designated by Lender) as
Borrower's attorney, with power whether before or after the occurrence of an
Event of Default: (a) to endorse Borrower's name on any checks, notes,
acceptances, money orders, drafts or other forms of payment or security that may
come into Lender's possession; (b) to sign Borrower's name on drafts against
Account Debtors, on schedules and assignments of Accounts, on verifications of
Accounts, and on notices to Account Debtors; (c) to notify the post office
authorities to change the address for delivery of Borrower's mail to an address
designated by Lender, to receive and open all mail addressed to Borrower and to
retain all mail relating to the Collateral and forward all other mail to
Borrower; (d) to send requests for verification of Accounts; (e) to execute UCC
Financing Statements; and (f) to do all things necessary to carry out this
Agreement. The appointment of Lender as Borrower's attorney and each and every
one of Lender's rights and powers, being coupled with an interest, are
irrevocable as long as any Obligations are outstanding. Lender agrees not to
exercise the power granted in clause 11.2(b) prior to the occurrence of an Event
of Default and agrees not to exercise the power granted in clause 11.2(d) prior
to notification of Borrower of its intent to do so, but such limitations do not
limit the effectiveness of such power of attorney at any time. Any person
dealing with Lender shall be entitled to rely conclusively on any written or
oral statement of Lender that this power of attorney is in effect. Lender may
also use Borrower's stationery in connection with exercising its rights and
remedies and performing the Obligations of Borrower.

               SECTION 11.3. EXPENSES SECURED All expenses, including attorney
fees, incurred by Lender in the exercise of its rights and remedies provided in
this Agreement, in the other Loan Documents or by law shall be payable by
Borrower to Lender, shall be part of the Obligations, and shall be secured by
the Collateral.

               SECTION 11.4. EQUITABLE RELIEF Borrower recognizes that in the
event Borrower fails to perform, observe, or discharge any of its Obligations or
liabilities under this Agreement, no remedy of law will provide adequate relief
to Lender, and Borrower agrees that Lender shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages.

               SECTION 11.5. REMEDIES ARE CUMULATIVE No remedy set forth herein
is exclusive of any other available remedy or remedies, but each is cumulative
and in addition to every other right or remedy given under this Agreement or
under any other agreement between Lender and Borrower or now or hereafter
existing at law or in equity or by statute. Lender may pursue its rights and
remedies concurrently or in any sequence, and no exercise of one right or remedy
shall be deemed to be an election. No delay by Lender shall constitute a waiver,
election or acquiescence by it.

                                   SECTION 12

                                    INDEMNITY

               SECTION 12.1. GENERAL INDEMNITY Borrower shall protect, indemnify
and defend and save harmless Lender and its directors, officers, agents and
employees from and against any and all loss, cost, liability (including
negligence, tort and strict liability), expense, damage, suits or demands
(including fees and disbursements of counsel) on account of any suit or
proceeding before any Governmental Authority which arises from the transactions
contemplated in this Agreement or otherwise arising in connection with or
relating to the Loan and any security therefor, unless such suit, claim or
damages are caused by the negligence or intentional malfeasance of Lender or its
directors, officer, agents or employees. Upon receiving knowledge of any suit,
claim or demand asserted by A third-party that Lender believes is covered by
this indemnity, Lender shall give Borrower timely notice of the matter and an
opportunity to defend it, at Borrower's sole cost and expense, with legal
counsel acceptable to Lender. Lender may, at its option, also require Borrower
to so defend the matter. This obligation on the part of Borrower shall survive
the termination of this Agreement and the repayment of the Note.

                                   SECTION 13

                                  MISCELLANEOUS

               SECTION 13.1. DELAY AND WAIVER No delay or omission to exercise
any right shall impair any such right or be a waiver thereof, but any such right
may be exercised from time to time and as often as may be deemed expedient. A
waiver on one occasion shall be limited to that particular occasion.

               SECTION 13.2. COMPLETE AGREEMENT This Agreement and the Schedules
are the complete agreement of the parties hereto and supersede all previous
understandings relating to the subject matter hereof. This Agreement may be
amended only by an instrument in writing that explicitly states that it amends
this Agreement and is signed by the party against whom enforcement of the
amendment is sought. This Agreement may be executed in counterparts, each of
which will be an original and all of which will constitute a single agreement.

               SECTION 13.3. SEVERABILITY; HEADINGS If any part of this
Agreement or the application thereof to any Person or circumstance is held
invalid, the remainder of this Agreement shall not be affected thereby. The
section headings herein are included for convenience only and shall not be
deemed to be a part of this Agreement.

               SECTION 13.4. BINDING EFFECT This Agreement shall be binding upon
and inure to the benefit of the respective legal representatives, successors and
assigns of the parties hereto; however, Borrower may not assign any of its
rights or delegate any of its Obligations hereunder. Lender (and any subsequent
assignee) may transfer and assign this Agreement and deliver the Collateral to
the assignee, who shall thereupon have all of the rights of Lender; and Lender
(or such subsequent assignee who in turn assigns as aforesaid) shall then be
relieved and discharged of any responsibility or liability with respect to this
Agreement and said Collateral.

               SECTION 13.5. NOTICES Any notices under or pursuant to this
Agreement shall be deemed duly sent when delivered in hand or when mailed by
registered or certified mail, return receipt requested, or when
