Collateral as the agent of, and as pledge holder for, the Secured Party.

perils, theft, burglary, and for any or all Collateral which are vehicles,
for risk of loss by collision, and where requested by Secured Party, against
other risks as required thereby, for the full replacement value thereof, with

change in the name of Debtor, (ii) any relocation of its chief executive

     (a)  Upon the occurrence of an Event of Default under this Agreement,
the Secured Party, at its option, may declare any or all of the Indebtedness,
including without limitation the Notes, to be immediately due and payable,
without demand or notice to Debtor or any Guarantor.  The obligations and
liabilities accelerated thereby shall bear interest (both before and after
any judgment) until paid in full at the lower of eighteen percent (18%) per
annum or the maximum rate not prohibited by applicable law.

     (b)  Upon such declaration of default, Secured Party shall have all of
the rights and remedies of a Secured Party under the Uniform Commercial Code,
and under any other applicable law.  Without limiting the foregoing, Secured
Party shall have the right to (i) notify any account debtor of Debtor or any
obligor on any instrument which constitutes part of the Collateral to make
payment to the Secured Party, (ii) with or without legal process, enter any
premises where the Collateral may be and take possession and/or remove said
Collateral from said premises, (iii) sell the Collateral at public or private
sale, in whole or in part, and have the right to bid and purchase at said

Collateral, applying proceeds therefrom to the obligations then in default.
If requested by Secured Party, Debtor shall promptly assemble the Collateral
and make it available to Secured Party at a place to be designated by Secured
Party which is reasonably convenient to both parties.  Secured Party may also
render any or all of the Collateral unusable at the Debtor's premises and may

<PAGE>

dispose of such Collateral on such premises without liability for rent or
costs.  Any notice which Secured Party is required to give to Debtor under
the Uniform Commercial Code of the time and place of any public sale or the
time after which any private sale or other intended disposition of the
Collateral is to be made shall be deemed to constitute reasonable notice if
such notice is given to the last known address of Debtor at least five (5)
days prior to such action.

     (c)  Proceeds from any sale or lease or other disposition shall be
applied: first, to all costs of repossession, storage, and disposition
including without limitation attorneys', appraisers', and auctioneers fees;
second, to discharge the obligations then in default; third, to discharge any
other Indebtedness of Debtor to Secured Party, whether as obligor, endorser,
guarantor, surety or indemnitor; fourth, to expenses incurred in paying or
settling liens claims against the Collateral; and lastly, to Debtor, if
there exists any surplus.  Debtor shall remain fully liable for any
deficiency.

     (d)  In the event this Agreement, any Note or any other Debt Documents
are placed in the hands of an attorney for collection of money due or to
become due or to obtain performance of any provision hereof, Debtor agrees to
pay all reasonable attorneys' fees incurred by Secured Party, and further
agrees that payment of such fees is secured hereunder.

     (e)  Secured Party's rights and remedies hereunder or otherwise arising
are cumulative and may be exercised singularly or concurrently.  Neither the
failure nor any delay on the part of the Secured Party to exercise any right,
power or privilege hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, power or privilege preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege.  Secured Party shall not be deemed to have waived any of its rights
hereunder or under any other agreement, instrument or paper signed by Debtor
unless such waiver be in writing and signed by Secured Party.  A waiver on
any one occasion shall not be construed as a bar to or waiver of any right or
remedy on any future occasion.

     (f)  DEBTOR HEREBY UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF
ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR
INDIRECTLY, THIS AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE
INDEBTEDNESS SECURED HEREBY, ANY DEALINGS BETWEEN DEBTOR AND SECURED PARTY
RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED
TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN
DEBTOR AND SECURED PARTY.  THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL
ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT
(INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY
CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS).  THIS WAIVER IS
IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,
SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT, ANY OTHER DEBT DOCUMENTS, OR
TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY
RELATED TRANSACTION.  IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED
AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

9.   MISCELLANEOUS.

     (a)  This Agreement, any Collateral Schedules, any Note and/or any of
the other Debt Documents may be assigned, in whole or in part, by Secured
Party without notice to Debtor, and Debtor hereby waives any defense,
counterclaim or cross-complaint by Debtor against any assignee, agreeing that
Secured Party shall be solely responsible therefor.  Debtor agrees that if
Debtor receives written notice of an assignment from Secured Party, Debtor
shall pay all payments and other amounts due under the assigned Note and
Collateral Schedule to such assignee or as instructed by Secured Party.
Debtor further agrees to confirm in writing receipt of the notice of
assignment as may be reasonably requested by Assignee.

     (b)  All notices to be given in connection with this Agreement shall be
in writing, shall be addressed to the parties at their respective addresses
set forth hereinabove (unless and until a different address may be specified
in a written notice to the other party), and shall be deemed given (i) on the
date of receipt if delivered in hand or by facsimile transmission, (ii) on
the next business day after being sent by express mail, and (iii) on the
fourth business day after being sent by regular, registered or certified
mail.  As used herein, the term "business day" shall mean and include any day
other than Saturdays, Sundays, or other days on which commercial banks in New
York, New York are required or authorized to be closed.

     (c)  Secured Party may correct patent errors herein and fill in all blanks
herein or in any Collateral Schedule consistent with the agreement of the
parties.

     (d)  Time is of the essence hereof.  This Agreement shall be binding,
jointly and severally, upon all parties described as the "Debtor" and their
respective heirs, executors, representatives, successors and assigns, and
shall inure to the benefit of Secured Party, its successors and assigns.

    (e)  This Agreement and its Collateral Schedules constitute the entire
agreement between the parties with respect to the subject matter hereof and
supersede all prior understandings (whether written, verbal or implied) with
respect thereto.  This Agreement and its Collateral Schedules shall not be
changed or terminated orally or by course of conduct, but only by a writing
signed by both parties hereto.  Section headings contained in this Agreement
have been included for convenience only, and shall not affect the
construction or interpretation hereof.

     (f)  This Agreement shall continue in full force and effect until all of
the Indebtedness has been indefeasibly paid in full to Secured Party.  The
surrender, upon payment or otherwise, of any Note or any of the other
documents evidencing any of the Indebtedness shall not affect the right of
Secured Party to retain the Collateral for such other Indebtedness as may
then exist or as it may be reasonably contemplated will exist in the future.
This Agreement shall automatically be reinstated in the event that Secured
Party is ever required to return or restore the payment of all or any portion
of the Indebtedness (all as though such payment had never been made).

     IN WITNESS WHEREOF, Debtor and Secured Party, intending to be legally
bound hereby, have duly executed this Agreement in one or more counterparts,
each of which shall be deemed to be an original, as of the day and year first
aforesaid.

Time is of the essence hereof.  If any installment or any other sum due under
this Note or any Security Agreement is not received within ten (10) days
after its due date, the Maker agrees to pay, in addition to the amount of
each such installment or other sum, a late payment charge of five percent
(5%) of the amount of said installment or other sum, but not exceeding any
lawful maximum.  In the event that (i) Maker fails to make payment of any
amount due hereunder within ten (10) days after the same becomes due and
payable; or (ii) Maker is in default under, or fails to perform under any
term or condition contained in any Security Agreement following any
applicable notice and/or cure period, then the entire principal sum remaining
unpaid, together with all accrued interest thereon and any other sum payable
under this Note or any Security Agreement, at the election of Payee, shall
immediately become due and payable, with interest thereon at the lesser of
500 basis points over the fixed interest rate payable hereunder or the
highest rate not prohibited by applicable law from the date of such
accelerated maturity until paid (both before and after any judgment).

The Maker may prepay in full, but not in part, its entire indebtedness
hereunder upon payment of an additional sum as a premium equal to the
following percentages of the remaining principal balance for the indicated
period:
          After the first anniversary and prior to the second annual
          anniversary date of this Note:  one percent (1)%
          Prior to the third annual anniversary date of this Note:  one
          percent (1)%
          Prior to the fourth annual anniversary date of this Note:  one
          percent (1)%
          and zero percent (0%) thereafter, plus all other sums due hereunder
          or under any Security Agreement

The Maker may not prepay the indebtedness prior to the first anniversary date
of this Note.

It is the intention of the parties hereto to comply with the applicable usury
laws; accordingly, it is agreed that, notwithstanding any provision to the
contrary in this Note or any Security Agreement, in no event shall this Note
or any Security Agreement require the payment or permit the collection of
interest in excess of the maximum amount permitted by applicable law.  If any
such excess interest is contracted for, charged or received under this Note
or any Security Agreement, or if all of the principal balance shall be
prepaid, so that under any of such circumstances the amount of interest
contracted for, charged or received under this Note or any Security Agreement
on the principal balance shall exceed the maximum amount of interest
permitted by applicable law, then in such event (a) the provisions of this
paragraph shall govern and control, (b) neither Maker nor any other person or
entity now or hereafter liable for the payment hereof shall be obligated to
pay the amount of such interest to the extent that it is in excess of the
maximum amount of interest permitted by applicable law, (c) any such excess
which may have been collected shall be either applied as a credit against the
then unpaid principal balance or refunded to Maker, at the option of the
Payee, and (d) the effective rate of interest shall be automatically reduced
to the maximum lawful contract rate allowed under applicable law as now or
hereafter construed by the courts having jurisdiction thereof.  It is further
agreed that without limitation of the foregoing, all calculations of the rate
of interest contracted for, charged or received under this Note or any
Security Agreement which are made for the purpose of determining whether such
rate exceeds the maximum lawful contract rate, shall be made, to the extent
permitted by applicable law, by amortizing, prorating, allocating and
spreading in equal parts during the period of the full stated term of the
indebtedness evidenced hereby, all interest at any time contracted for,
charged or received from Maker or otherwise by Payee in connection with such
indebtedness; provided, however, that if any applicable state law is amended
or the law of the United States of America preempts any applicable state law,
so that it becomes lawful for the Payee to receive a greater interest per
annum rate than is presently allowed, the Maker agrees that, on the effective
date of such amendment or preemption, as the case may be, the lawful maximum
hereunder shall be increased to the maximum interest per annum rate allowed
by the amended state law or the law of the United States of America.

The Maker and all sureties, endorsers, guarantors or any others (each such
person, other than the Maker, an "Obligor") who may at any time become liable
for the payment hereof jointly and severally consent hereby to any and all
extensions of time, renewals, waivers or modifications of, and all
substitutions or releases of, security or of any party primarily or
secondarily liable on this Note or any Security Agreement or any term and
provision of either, which may be made, granted or consented to by Payee, and
agree that suit may be brought and maintained against any one or more of
them, at the election of Payee without joinder of any other as a party
thereto, and that Payee shall not be required first to foreclose, proceed
against, or exhaust any security hereof in order to enforce payment of this
Note.  The Maker and each Obligor hereby waives presentment, demand for
payment, notice of nonpayment, protest, notice of protest, notice of
dishonor, and all other notices in connection herewith, as well as filing of
suit (if permitted by law) and diligence in collecting this Note or enforcing
any of the security hereof, and agrees to pay (if permitted by law) all
reasonable expenses incurred in collection, including Payee's actual
attorneys' fees.
