1.      INTEREST RATE. Maker shall pay interest ("INTEREST") on the unpaid

maturity or judgment). Interest due hereunder shall be paid in arrears monthly
beginning on March 13, 2002.

        Anything contained in this Note to the contrary notwithstanding, Payee

other charges in excess of the maximum rate permitted by applicable law. Any
payments in excess of such maximum rate shall be refunded to Maker or credited
against principal.

2.      PAYMENTS OF PRINCIPAL AND INTEREST. All outstanding principal, together
with accrued and unpaid Interest thereon, shall be due and payable by Maker to
Payee on February 13, 2007.

3.      PREPAYMENTS.

without penalty or premium, by paying to Payee the principal amount to be
prepaid together with interest accrued thereon to the date of prepayment.
Prepayments pursuant to the immediately preceding sentence or Section 3(b) below
shall first be applied to accrued and unpaid interest, and then to unpaid
principal. Any principal amount of this Note prepaid may not be reborrowed.

        (b)    Mandatory Prepayment. Without limiting the provisions of Sections
2 and 3(a) above, after satisfaction and payment in full of all of Maker's
obligations under that certain Secured Promissory Note in the principal amount
of $500,000 issued by Maker to Payee (the "FIRST INSTALLMENT NOTE"), Maker shall
in addition prepay this Note in the following amounts, in each case exclusive of
any proceeds applied toward prepayment of the First Installment Note (it being
understood that such prepayments shall be applied first to accrued and unpaid
Interest and then to principal): (i) 100% of the cash proceeds (net of
collection costs (including reasonable attorney's fees and disbursements related
to such collection)) received by Maker after the date of the First Installment
Note with respect to the first $600,000, in the aggregate, of accounts
receivable derived from Maker's "Professional Services" business or "Managed
Services" business (the "RECEIVABLES"), (ii) 20% of the excess (if any) of the

disbursements related to such collection)) received by Maker with respect to the
Receivables in excess of $600,000, in the aggregate, from the date of the First
Installment Note, (iii) 100% of the amount of the direct or indirect (including
from any disposition of any non-cash consideration for cash or marketable
securities) cash proceeds or marketable securities (at fair market value, taking
into account any applicable illiquidity and minority discounts) (net of
reasonable attorney's fees and disbursements related to such sale or
disposition) received on account of or with respect to any sale or other
disposition of all or any portion of Maker's interest in E-Sync Networks, LLC,
and (iv) 100% of all cash payments received by Maker with respect to any
exercise of that certain Common Stock Purchase Warrant issued by Maker to Payee
on the date of the First Installment Note. Prepayments pursuant to the

constitute an "EVENT OF DEFAULT":

        (a)    Maker shall fail to make any payment of any principal, Interest
or other amount when due under this Note or the First Installment Note;
provided, however, that the failure of Maker to make any payment of Interest due

this Note shall not constitute an Event of Default, provided that Interest shall
accrue at the rate of fifteen percent (15%) until all accrued and payable
Interest thereof is paid in full.

        (b)    Maker shall be dissolved or shall make an assignment of all or
substantially all of its assets for the benefit of creditors; or shall have a

Maker, the same remains undismissed for a period of thirty (30) days).

        (d)    Maker shall admit in writing its inability to pay its debts as
they become due; provided, however, that any such admission to which Payee has

Default, Payee, at Payee's option and without the need for presentment, demand,
protest or other notice of any kind, may declare all unpaid principal hereof and
Interest hereunder to be immediately due and payable, and the same shall become

the provisions of JAMS' comprehensive Arbitration Rules and Procedures in effect
at the time of filing of the demand for arbitration. The parties will cooperate

remedy hereunder or under any guaranty hereof, or with respect to any collateral
or other security or surety related to this Note or Maker's obligations
hereunder, shall operate as a waiver of such right or remedy or any other right
or remedy, and a waiver on one occasion of any right or remedy shall not be a
bar to, or constitute a waiver, of such right or remedy on any other occasion or
of any other right or remedy on any occasion. All rights and remedies of Payee
hereunder, under any other applicable document and under applicable law shall be
cumulative and not in the alternative. No provision of this Note or any guaranty
