        (a) the Maker fails to make any payment of principal or interest
hereunder when due;

        (c) a receiver or trustee shall be appointed for Maker or any
substantial part of its assets, or any proceedings shall be instituted for the
dissolution or the full or partial liquidation of Maker and such receiver or
trustee shall not be discharged within 30 days of his appointment, or such

business.

protest of this Note (other than any notices required herein).

     8. ACCELERATION. If an Event of Default set forth in Section 6 occurs and
is continuing, the Holder may, by written notice (the "Acceleration Notice") to
the Maker, declare all unpaid principal and accrued interest on this Note then

or any notice of any kind, all of which are hereby expressly waived anything
contained herein to the contrary notwithstanding.

     9. RESCISSION; REMEDIES. The Holder by written notice to the Maker may
rescind a declaration of acceleration. A delay or omission by the Holder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. No remedy is exclusive of any other remedy. All available
remedies are cumulative to the extent permitted by law.

                   SECTION 3 - DEBTOR'S AFFIRMATIVE COVENANTS

     Debtor covenants and agrees that, from and after the date of this Agreement
and so long as Debtor shall be indebted to Secured Party, unless Secured Party
shall otherwise consent in writing, it will comply with the following covenants:

     3.1 NOTICE OF DEFAULT. If any officer of Debtor knows of any Event of
Default which shall have occurred or knows of the occurrence of any event which,
upon notice or passage of time, or both, would constitute an Event of Default,
Debtor shall immediately, upon acquiring knowledge of same, furnish to Secured
Party a statement as to such occurrence, specifying the nature and extent
thereof. If Debtor receives a notice of default from any creditor other than
Secured Party, Debtor shall deliver to Secured Party a copy of such notice of
default immediately upon its receipt thereof.

     3.2 DEFENSE OF TITLE AND FURTHER ASSURANCES. Debtor shall, at its sole
expense, defend title to the Collateral and promptly, upon Secured Party's
request, do, execute, acknowledge and deliver or cause to be done, executed,
acknowledged and delivered, all such further acts, deeds, instruments,
transfers, powers of attorney, mortgages or assurances as may be required in
connection with the transactions contemplated by this Agreement, including any
security agreement, financing statement or other writing necessary to evidence,
preserve, protect or enforce Secured Party's rights and interests to or in the
Collateral or in any other collateral security agreed to by the parties hereto.

     3.3 LIMITATION ON SALE OF PURCHASED ASSETS. Debtor shall not sell, assign,
transfer, lease, convey, abandon or otherwise dispose of, voluntarily or
involuntarily, any of the Purchased Assets or income or profits therefrom.

     3.4 MAINTENANCE OF COLLATERAL. Debtor shall not move any of the Collateral
from the locations specified in Section 4.2 without (a) giving Secured Party 30
days prior written notice and (b) first taking all action required by Section
2.3 with respect to such Collateral.

     3.5 COMPLIANCE WITH AGREEMENT. Debtor shall observe, perform and comply
with all of Debtor's covenants made in this Agreement and with all material
agreements to which it is subject.

                   SECTION 4 - REPRESENTATIONS AND WARRANTIES

     To induce Secured Party to enter into this Agreement, Debtor represents and
warrants to Secured Party as follows:

     4.1 SECURITY. The provisions of this Agreement are effective to create in
favor of Secured Party a legal, valid and enforceable security interest in all
right, title and interest of Debtor in the Collateral as described herein, and
when financing statements have been filed in the offices of the jurisdictions in
which such property is located, this Agreement shall constitute a fully
perfected Lien on all right, title and interest of Debtor in the Collateral
described herein, subject to no prior Liens. The property which is subject to
the Lien hereunder constitutes all the property of any nature of Debtor acquired
pursuant to the Asset Purchase Agreement.

     4.2 LOCATION OF COLLATERAL. The location of the collateral is at the
address set forth on Exhibit A hereto. In the event that Debtor discovers that
any representation made in this

<PAGE>

Section is untrue or incorrect for any reason, it will immediately notify
the Secured Party and take such actions as may be necessary to make such
representation true and correct.

     4.3 ASSET PURCHASE AGREEMENT REPRESENTATIONS. No representation or warranty
by Debtor contained in the Asset Purchase Agreement or in any certificate or
other document furnished by Debtor pursuant thereto contains any untrue
statement of material fact or omits to state a material fact necessary to make
such representation or warranty not misleading in light of the circumstances
under which it was made.

     4.4 LOAN REPRESENTATIONS. No representation or warranty by Debtor contained
herein or in any certificate or other document furnished by Debtor pursuant
hereto contains any untrue statement of material fact or omits to state a
material fact necessary to make such representation or warranty not misleading
in light of the circumstances under which it was made.

                               SECTION 5 - DEFAULT

     5.1 EVENTS OF DEFAULT. The occurrence of any one or more of the following
shall constitute an Event of Default hereunder:

        (a) Debtor shall fail to pay when due, any payment of principal,
interest, fees or expenses payable under the Note.

        (b) Debtor shall fail to observe or perform any obligation (including,
but not limited to, the obligations contained in Section 7.2 of the Asset
Purchase Agreement), other than the obligation for payment of money under the
Note, and such failure shall continue for 10 days after the earlier of (1) the
date written notice of such failure is mailed by Secured Party, or (2) the date
Secured Party is notified of such failure or should have been so notified
pursuant to the provisions hereof.

        (c) Any representation, warranty or certificate made or furnished by or
on behalf of Debtor to Secured Party in connection with this Agreement shall be
materially false, incorrect, incomplete or misleading when made.

        (d) Debtor shall admit its inability to pay its debts as they mature, or
shall make an assignment for the benefit of its creditors.

        (e) Proceedings in bankruptcy, or for reorganization of Debtor, or for
the readjustment of any of its debts, under the Bankruptcy Code or any part
thereof, or under any other Laws, whether state or federal, for the relief of
debtors, now or hereafter existing, shall be commenced by Debtor, or shall be
commenced against Debtor, which proceedings against Debtor shall not be
discharged within 30 days of their commencement.

        (f) A receiver or trustee shall be appointed for Debtor or any
substantial part of its assets, or any proceedings shall be instituted for the
dissolution or the full or partial liquidation of Debtor and such receiver or
trustee shall not be discharged within 30 days of his appointment, or such
proceedings shall not be discharged within 30 days of their commencement, or
Debtor shall discontinue business or materially change the nature of its
business.

<PAGE>

        (g) Debtor shall suffer a final judgment for the payment of money in
excess of $500,000 and shall not discharge the same within a period of 30 days
unless execution thereon is effectively bonded or stayed pending further
proceedings.

        (h) Any execution or attachment shall be levied against the Collateral
or any properties of Debtor, and such execution or attachment shall not be set
aside, discharged or stayed within 30 days after the same shall have been
levied.

          SECTION 6 - SECURED PARTY'S RIGHTS AND REMEDIES UPON DEFAULT

     6.1 ACCELERATION. Upon the occurrence of an Event of Default (other than
under Section 5.1(f)), and in every such event and at any time thereafter,
Secured Party may, at its option, declare all Obligations due and payable,
without presentment, demand, protest or any notice of any kind, all of which are
hereby expressly waived, anything contained herein or in any of the other Loan
Documents to the contrary notwithstanding. Upon the occurrence of an Event of
Default under Section 5.1(f), all Obligations shall immediately become due and
payable, without presentment, demand, protest or any notice of any kind, all of
which are hereby expressly waived anything contained herein or in any of the
other Loan Documents to the contrary notwithstanding.

     6.2 REMEDIES. Secured Party shall have, in addition to the rights and
remedies given it by this Agreement, all those allowed by all applicable Laws,
including, without limitation, the Uniform Commercial Code. Without limiting the
generality of the foregoing, Secured Party may immediately, without demand or
notice of any kind to Debtor (except as specifically required by this
Agreement), all of which are hereby expressly waived, and without advertisement,
sell at public or private sale or otherwise realize upon the whole or, from time
to time, any part of the Collateral, or any interest which Debtor may have
therein. After deducting from the proceeds of sale or other disposition of the
Collateral all expenses (including all expenses for legal services), Secured
Party shall apply such proceeds toward the satisfaction of the Obligations, in
such order as it shall determine in its sole discretion. Any remainder of the
proceeds after satisfaction in full of the Obligations shall be distributed as
required by applicable Laws. At any such sale or other disposition, Secured
Party may, to the extent permissible under applicable Laws, purchase the whole
or any part of the Collateral, free from any rights of redemption or
appraisement on the part of Debtor, which rights are hereby waived and released.
Notice of any sale or other disposition shall be given to Debtor at the address
hereinafter set forth, or such other address of Debtor as may from time to time
be shown on Secured Party's records, at least five days before the time of any
intended public sale or the time after which any intended private sale or other
disposition of the Collateral is to be made, which Debtor hereby agrees shall be
reasonable notice of such sale or other disposition. Debtor agrees to assemble,
or to cause to be assembled, at its own expense, the Collateral at such place or
places as Secured Party shall designate. Without limiting the generality of any
of the rights and remedies conferred upon Secured Party under this section,
Secured Party may, to the full extent permitted by applicable Laws:

        (a) enter upon the premises of Debtor, exclude and remove therefrom all
officers, directors and employees of Debtor and take immediate possession of the
Collateral, either personally or through any agent, or by means of a receiver
appointed by a court of competent jurisdiction, using all necessary force to do
so (in Secured Party's sole discretion);

        (b) at Secured Party's option, use, operate, manage and control the
Collateral in any lawful manner;

<PAGE>

        (c) collect, receive and administer all rents, income, revenue,
earnings, issues and profits (including the Accounts), and proceeds therefrom;

        (d) maintain, repair, renovate, alter or remove all or any part of the
Collateral, as Secured Party may determine in its sole discretion;

        (e) make exchanges, substitutions or surrenders of all or any part of
the Collateral;

        (f) compromise, extend or renew any of the Collateral or deal with the
same as it may deem advisable;

        (g) notify postal authorities to change the address for the delivery of
mail to Debtor to such address or post office box as Secured Party may designate
and receive and open all mail addressed to Debtor;

        (h) remove from Debtor's place of business all records relating to or
evidencing any of the Collateral or without cost or expense to Secured Party
make such use of the Debtor's place of business as may be reasonably necessary
to administer, manage and collect the Collateral;

        (i) institute and prosecute legal and equitable proceedings to enforce
collection of the Obligations of Debtor to Secured Party, or to realize upon any
of the Collateral;

        (j) settle, renew, extend, compromise, compound, exchange or adjust
claims in respect of any of the Collateral or any legal proceedings brought in
respect thereof;

        (k) subrogate to all of Debtor's interests, rights and remedies in
respect to the Collateral, including the right to stop delivery and to reclaim
Collateral which the account debtor has returned, rejected, revoked acceptance
of or failed to return, and which have been consigned or diverted, to take
possession of and to sell or dispose of the Collateral;

        (l) set off and apply to all or any part of the Obligations all moneys,
credits and other property of any nature whatsoever of Debtor now or any time
hereafter in the possession of Secured Party or of any Person on behalf of
Secured Party, in transit to or from Secured Party, or under the control or
custody of or on deposit with Secured Party;

        (m) if Debtor shall fail to pay the Obligations or otherwise fail to
perform, observe or comply with any of the conditions, covenants, terms,
stipulations or agreements contained in this Agreement, Secured Party, without
notice to or demand upon Debtor and without waiving or releasing any of the
Obligations or any Event of Default, may (but shall be under no obligation to)
at any time thereafter make such payment or perform such act for the account and
at the expense of Debtor, and may enter upon the premises of Debtor for that
purpose and take all such action thereon as Secured Party may consider necessary
or appropriate for such purpose. All sums so paid or advanced by Secured Party
and all costs and expenses (including, without limitation, attorneys' fees and
expenses) incurred in connection therewith, together with interest thereon at
the interest rate charged on the Note from the date of payment, advance or
incurring until paid in full, shall be paid by Debtor to Secured Party, on
demand, and shall constitute and become a part of the Obligations; and

<PAGE>

        (n) such other and further acts and deeds in the name of Debtor as
Secured Party may deem necessary or advisable to the extent necessary for
Secured Party to realize upon any of the Collateral.

     6.3 ENFORCEMENT AND WAIVER BY SECURED PARTY. Secured Party shall have the
right at all times to enforce the provisions of this Agreement and the documents
delivered pursuant hereto in strict accordance with the terms hereof and
thereof, notwithstanding any conduct or custom on the part of Secured Party in
refraining from so doing at any time or times. The failure or delay of Secured
Party at any time or times to enforce its rights and remedies under such
provisions, strictly in accordance with the same, shall not be construed as
having created a custom in any way or manner contrary to specific provisions of
this Agreement or as having in any way or manner modified or waived the same.
All rights and remedies of Secured Party are cumulative and concurrent, may be
exercised by Secured Party singly, successively or together, or at such time or
times and in such order of preference as Secured Party may so determine, and the
exercise of one right or remedy by Secured Party shall not be deemed a waiver of
any other right or remedy.

                            SECTION 7 - MISCELLANEOUS

     7.1 CONSTRUCTION. The provisions of this Agreement shall be in addition to
those of any guaranty, security agreement, note or other evidence of liability
held by Secured Party, all of which shall be construed as complementary to each
other. In the event of ambiguity or inconsistency between this Agreement and any
agreement, document or instrument made pursuant hereto, the terms of this
Agreement shall govern. Nothing herein contained shall prevent Secured Party
from enforcing the Note, any or all other notes, guarantees or security
agreements in accordance with their respective terms.

     7.2 FURTHER ASSURANCE. From time to time, Debtor will execute and deliver
to Secured Party such additional documents and will provide such additional
information as Secured Party may reasonably require, to carry out the terms of
this Agreement and to be informed of Debtor's status and affairs.

     7.3 COSTS, EXPENSES AND FEES PAID AND PAYABLE TO SECURED PARTY.

         (a) Debtor agrees to pay on demand all attorneys' fees, search fees,
filing fees and other expenses incurred by Secured Party in connection with the
preparation, administration or enforcement of this Agreement or other Loan
Documents, or any renewal, extension, amendment or modification of this
Agreement and other Loan Documents, and all such fees and expenses shall be a
part of the Obligations hereunder and shall be paid on the Closing Date or at
such later time as services are performed or expenses incurred.

         (b) Debtor agrees that all costs, expenses and reasonable attorneys'
fees incidental to the custody, care, management, sale or collection of, or
realization upon, any of the Collateral or in any way relating to the care,
enforcement or protection of the Collateral or the enforcement of any and all
rights of Secured Party either hereunder or under any applicable law or custom,
shall become part of the Obligations, be payable on demand, and be entitled to
the benefit of this Agreement, and Secured Party may at any time apply to the
payment of all such costs and expenses all moneys of Debtor or other proceeds
arising from the possession or disposition of all or any portion of the
Collateral.
