Bank:                                         Borrower:

BANK OF AMERICA, N.A.                         DALEEN TECHNOLOGIES, INC., a
Banking Center: CLSC CENTER                   Delaware corporation

                                              County: Palm Beach

================================================================================

FOR VALUE RECEIVED, the undersigned Borrower unconditionally (and jointly and
severally, if more than one) promises to pay to the order of Bank, its
successors and assigns, without setoff, at its offices indicated at the
beginning of this Note, or at such other place as may be designated by Bank in
writing, the principal amount of TEN MILLION AND 00/100 Dollars
($10,000,000.00), or so much thereof as may be advanced to Borrower hereunder in
immediately available funds, together with interest computed daily on the
outstanding principal balance hereunder, at an annual interest rate, and in
accordance with the payment schedule, indicated below.

1. RATE.

                  VARIABLE INTEREST RATE. The interest rate on this Note is
subject to change from time to time based on changes in an independent index
which is the "Wall Street Journal LIBOR Rate" which is a fluctuating rate of
interest equal to the 1 MONTH London interbank offered rate as published in the
"Money Rates" section of the Wall Street Journal on the immediately preceding
business day as adjusted from time to time in Lender's sole discretion for then
applicable reserve requirements, deposit insurance assessment rates and other
regulatory costs (the "Index"). The index is not necessarily the lowest charged
by Lender on its loans. If the Index becomes unavailable during the term of this
loan, Lender may designate a substitute index after notice to Borrower. Lender
will tell Borrower the current index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate will adjust on the same day as any change occurs in the index. The
index currently is 6.62% per annum. The interest rate to be applied to the
unpaid principal balance of this Note will be at a rate of 1.25 percentage
points over the index, resulting in an inital rate of 7.87% per annum. NOTICE:
Under no circumstances will the effected rate on this Note be more than the
maximum rate allowed by applicable law.

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by the applicable law of the State of Florida;
if any higher rate ceiling is lawful, then that higher rate ceiling shall apply.
Any payment in excess of such maximum shall be refunded to Borrower or credited
against principal, at the option of Bank.

2. ACCRUAL METHOD. Unless otherwise indicated, interest at the Rate set forth
above will be calculated by the actual/360 day method (a daily amount of
interest is computed for a hypothetical year of 360 days; that amount is
multiplied by the actual number of days for which any principal is outstanding
hereunder).

3. PAYMENT SCHEDULE. All payments received hereunder shall be applied first to
the payment of any expense or charges payable hereunder or under any other loan
documents executed in connection with this Note, then to interest due and
payable, with the balance applied to principal, or in such other order as Bank
shall determine at its option.

4. SINGLE PRINCIPAL PAYMENT. Principal shall be paid in full in a single payment
on the maturity date (`maturity") of February 28, 2002. Interest thereon shall
be paid MONTHLY, commencing on September 28, 2000, and continuing on the SAME
day of each successive month, thereafter, with a final payment of all unpaid
interest at the stated maturity of this Note.

5. REVOLVING FEATURE.

[X] Borrower may borrow, repay and reborrow hereunder at any time, up to a
maximum aggregate amount outstanding at any one time equal to the principal
amount of this Note, provided, that Borrower is not in default under any
provision of this Note, any other documents executed in connection with this
Note, or any other note or other loan documents now or hereafter executed in
connection with any other obligation of Borrower to Bank, and provided




                                       1
<PAGE>   2

that the borrowings hereunder do not exceed any borrowing base or other
limitation on borrowings by Borrower. Bank shall incur no liability for its
refusal to advance funds based upon its determination that any conditions of
such further advances have not been met. Bank records of the amounts borrowed
from time to time shall be conclusive proof thereof.

6. AUTOMATIC PAYMENT. Borrower authorizes Bank to effect payment of sums due
under this Note by means of debiting Borrower's account number 3446412343. This
authorization shall not affect the obligation of Borrower to pay such sums when
due, without notice, if there are insufficient funds in such account to make
such payment in full on the due date thereof, or if Bank fails to debit the
account.

7. WAIVERS, CONSENTS AND COVENANTS. Subject to the applicable cure periods set
forth in Section 11 below and in Section 6 of the "Loan Agreement" by and
between Bank and Borrower dated August 18, 2000, Borrower, any indorser or
guarantor hereof, or any other party hereto (individually an "Obligor" and
collectively "Obligors") and each of them jointly and severally: (a) waive
presentment, demand, protest, notice of demand, notice of intent to accelerate,
notice of acceleration of maturity, notice of protest, notice of nonpayment,
notice of dishonor, and any other notice required to be given under the law to
any Obligor in connection with the delivery, acceptance, performance, default or
enforcement of this Note, any indorsement or guaranty of this Note, or any other
documents executed in connection with this Note or any other note or other loan
documents now or hereafter executed in connection with any obligation of
Borrower to Bank (the "Loan Documents"); (b) consent to all delays, extensions,
renewals or other modifications of this Note or the Loan Documents, or waivers
of any term hereof or of the Loan Documents, or release or discharge by Bank of
any of Obligors, or release, substitution or exchange of any security for the
payment hereof, or the failure to act on the part of Bank, or any indulgence
shown by Bank (without notice to or further assent from any of Obligors), and
agree that no such action, failure to act or failure to exercise any right or
remedy by Bank shall in any way affect or impair the obligations of any Obligors
or be construed as a waiver by Bank of, or otherwise affect, any of Bank's
rights under this Note, under any indorsement or guaranty of this Note or under
any of the Loan Documents; and (c) agree to pay, on demand, all costs and
expenses of collection or defense of this Note or of any indorsement or guaranty
hereof and/or the enforcement or defense of Bank's rights with respect to, or
the administration, supervision, preservation, or protection of, or realization
upon, any property securing payment hereof, including, without limitation,
reasonable attorney's and paralegals fees, including fees related to any suit,
mediation or arbitration proceeding, out of court payment agreement, trial,
appeal, bankruptcy proceedings or other proceeding, in such amount as may be
determined reasonable by any arbitrator or court, whichever is applicable.

8. INDEMNIFICATION. Obligors agree to promptly pay, indemnify and hold Bank
harmless from all State and Federal taxes of any kind and other liabilities with
respect to or resulting from the execution and/or delivery of this Note or any
advances made pursuant to this Note. If this Note has a revolving feature and is
secured by a mortgage, Obligors expressly consent to the deduction of any
applicable taxes from each taxable advance extended by Bank.

9. PREPAYMENTS. Prepayments may be made in whole or in part at any time on any
loan for which the Rate is based on the Prime Rate or any other fluctuating Rate
or index which may change daily. All prepayments of principal shall be applied
in the inverse order of maturity, or in such other order as Bank shall determine
in its sole discretion. No prepayment of any other loan shall be permitted
without the prior written consent of Bank. Notwithstanding such prohibition, if
there is a prepayment of any such loan, whether by consent of Bank, or because
of acceleration or otherwise, Borrower shall, within 15 days of any request by
Bank, pay to Bank any loss or expense which Bank may incur or sustain as a
result of such prepayment. For the purposes of calculating the amounts owed
only, it shall be assumed that Bank actually funded or committed to fund the
loan through the purchase of an underlying deposit in an amount and for a term
comparable to the loan, and such determination by Bank shall be conclusive,
absent a manifest error in computation.

10. DELINQUENCY CHARGE. To the extent permitted by law, a delinquency charge may
be imposed in an amount not to exceed four percent (4%) of any payment that is
more than fifteen days late.

11. EVENTS OF DEFAULT. The following are events of default hereunder and are
subject to the following cure periods, thirty (30) days from Borrower's receipt
of written notice from Bank in the event of a non-monetary default and fifteen
(15) days in the case of a monetary default by Borrower (written notice shall
not be required for monetary defaults): (a) the failure to pay or perform any
obligation, liability or indebtedness of any Obligor to Bank, or to any
affiliate or subsidiary of Bank of America Corporation, whether under this Note
or any Loan Documents, as and when due (whether upon demand, at maturity or by
acceleration); (b) the commencement of a proceeding against any Obligor for
dissolution or liquidation, the voluntary or involuntary termination or
dissolution of any Obligor; (c) the insolvency of, the business failure of, the
appointment of a custodian, trustee, liquidator or receiver for or for any of
the property of, the assignment for the benefit of creditors by, or the filing
of a petition under bankruptcy, insolvency or debtor's relief law or the filing
of a petition for any adjustment of indebtedness, composition or extension by or
against any Obligor; (d) the determination by Bank that any representation or
warranty made to Bank by any Obligor in any Loan Documents or otherwise is or
was, when it was made, untrue or materially misleading; (e) the entry of a
judgment against any Obligor which will have a material adverse affect on the
business of the Borrower which Bank, in its reasonable opinion deems to be of a
material nature; (f) the seizure or forfeiture of, or the issuance of any writ
of possession, garnishment or attachment, or any turnover order for any property
of any Obligor; or (g) the failure of Borrower's business to materially comply
with any law or regulation controlling its operation.

12. REMEDIES UPON DEFAULT. Whenever there is a default under this Note which has
not been cured by Borrower during the applicable cure period, then (a) the
entire balance outstanding hereunder and all other obligations of any Obligor to
Bank (however acquired or evidenced) shall, at the



                                       2
<PAGE>   3
option of Bank, become immediately due and payable and any obligation of Bank to
permit further borrowing under this Note shall immediately cease and terminate,
and/or (b) to the extent permitted by law, the Rate of interest on the unpaid
principal shall be increased at Bank's discretion up to the maximum of the
Bank's Prime rate plus 3% (the "Default Rate"). The provisions herein for a
Default Rate shall not be deemed to extend the time for any payment hereunder or
to constitute a "grace period" giving Obligors a right to cure any default. At
Bank's option, any accrued and unpaid interest, fees or charges may, for
purposes of computing and accruing interest on a daily basis after the due date
of the Note or any installment thereof, be deemed to be a part of the principal
balance, and interest shall accrue on a daily compounded basis after such date
at the Default Rate provided in this Note until the entire outstanding balance
of principal and interest is paid in full. Upon a default under this Note, Bank
is hereby authorized at any time, at its option and without notice or demand, to
set off and charge against any deposit accounts of any Obligor (as well as any
money, instruments, securities, documents, chattel paper, credits, claims,
demands, income and any other property, rights and interests of any Obligor),
which at any time shall come into the possession or custody or under the control
of Bank or any of its agents, affiliates or correspondents, any and all
obligations due hereunder. Additionally, Bank shall have all rights and remedies
available under each of the Loan Documents, as well as all rights and remedies
available at law or in equity. Any judgment rendered on this Note shall bear
interest at the highest rate of interest permitted pursuant to Chapter 687,
Florida Statutes.

13. NON-WAIVER. The failure at any time of Bank to exercise any of its options
or any other rights hereunder shall not constitute a waiver thereof, nor shall
it be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of Bank's
rights under this Note. No waiver of any of its rights hereunder, and no
modification or amendment of this Note, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; each such
waiver shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Bank or the obligations of Obligors to Bank
in any other respect at any other time.

14. APPLICABLE LAW, VENUE AND JURISDICTION. This Note and the rights and
obligations of Borrower and Bank shall be governed by and interpreted in
accordance with the law of the State of Florida. In any litigation in connection
with or to enforce this Note or any indorsement or guaranty of this Note or any
Loan Documents, Obligors, and each of them, irrevocably consent to and confer
personal jurisdiction on the courts of the State of Florida or the United States
located within the State of Florida and expressly waive any objections as to
venue in any such courts. Nothing contained herein shall, however, prevent Bank
from bringing any action or exercising any rights within any other state or
jurisdiction or from obtaining personal jurisdiction by any other means
available under applicable law. The interest rate charged on this Note is
authorized by Chapter 655, Florida Statutes and Section 687.12, Florida
Statutes.

15. PARTIAL INVALIDITY. The unenforceability or invalidity of any provision of
this Note shall not affect the enforceability or validity of any other provision
herein and the invalidity or unenforceability of any provision of this Note or
of the Loan Documents to any person or circumstance shall not affect the
enforceability or validity of such provision as it may apply to other persons or
circumstances.

16. BINDING EFFECT. This Note shall be binding upon and inure to the benefit of
Borrower, Obligors and Bank and their respective successors, assigns, heirs and
personal representatives, provided, however, that no obligations of Borrower or
Obligors hereunder can be assigned without prior written consent of Bank.

17. CONTROLLING DOCUMENT. To the extent that this Note conflicts with or is in
any way incompatible with any other document related specifically to the loan
evidenced by this Note, this Note shall control over any other such document,
and if the Note does not address an issue, then each other such document shall
control to the extent that it deals most specifically with an issue.
