         FLOATING RATE JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE

                                DUE JUNE 30, 2032

No. _________                               Four Million One Hundred Twenty-Five
Thousand Dollars ($4,125,000)

         United Bancorporation of Alabama, Inc., a Delaware corporation (the
"Company," which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to, Wells
Fargo Bank, National Association or any successor thereto, as property trustee
of United Bancorp Capital Trust I or registered assigns, the principal sum of
Four Million One Hundred Twenty-Five Thousand Dollars ($4,125,000) on June 30,
2032 (the "Stated Maturity"), and to pay interest on said principal sum from
June 27, 2002, or from the most recent interest payment date to which interest
has been paid or duly provided for, quarterly (subject to deferral as set forth
herein) in arrears on March 30, June 30, September 30 and December 30 of each
year (each such date, an "Interest Payment Date") commencing September 30, 2002,
at the rate of 3.65% per annum over the Three-Month LIBOR Rate (the "Floating
Interest Rate"), applied to the aggregate principal amount of the Debentures
Outstanding as of such Interest Payment Date, until the principal hereof shall
have become due and payable, and on any overdue principal and (without
duplication and to the extent that payment of such interest is enforceable under
applicable law) on any overdue installment of interest at the same rate per
annum compounded quarterly. In no event shall the Floating Interest Rate exceed
12% prior to June 30, 2007.

         The "Three-Month LIBOR Rate" shall mean the rate determined in
accordance with the following provisions:

                  (i) On the second LIBOR BUSINESS DAY (provided that on such
         day commercial banks are open for business (including dealings in
         foreign currency deposits) in London (a "LIBOR Banking Day") preceding
         each of January 15, April 15, July 15 and October 15 (except with
         respect to June 27, 2002 (each such date, a "Interest Reset Date"),
         Wells Fargo Bank, National Association (the "Calculation Agent"), will
         determine the Three-Month LIBOR Rate which shall be the rate for
         deposits in the London interbank market in U.S. dollars having a
         three-month maturity which appears on the Telerate Page 3750 as of
         11:00 a.m., London time, on such Interest Reset Date. "Telerate Page
         3750" means the display on Page 3750 of the Bloomberg Financial Markets
         Commodities News (or such other page as may replace that page on that
         service for the purpose of displaying London interbank offered rates of
         major banks for U.S. dollar deposits). If the Three-Month LIBOR Rate on
         such Interest Reset Date does not appear on the Tleerate Page 3750,
         such Three-Month LIBOR Rate will be determined as described in (ii)
         below. "LIBOR Business Day" means any day that is not a Saturday,
         Sunday or other day on which commercial banking institutions in New
         York, New York or Wilmington, Delaware are authorized or obligated by
         law or executive order to be closed. If such rate is superseded on
         Telerate Page 3750 by a corrected rate before 12:00

                                       -3-
<PAGE>

         noon (London time) on the same Interest Reset Date, the corrected rate
         as so substituted will be the applicable LIBOR for that Interest Reset
         Date.

                  (ii) If, on any Interest Reset Date, such rate does not appear
         on Telerate Page 3750 as reported by Bloomberg Financial Markets
         Commodities News or such other page as may replace such Telerate Page
         3750, the Calculation Agent shall determine the arithmetic mean of
         quotations of the Reference Banks (defined below) to leading banks in
         the London interbank market for three-month U.S. Dollar deposits in
         Europe (in an amount determined by the Calculation Agent) by reference
         to requests for quotations as of approximately 11:00 a.m. (London time)
         on the Interest Reset Date made by the Calculation Agent to the
         Reference Banks. If, on any Interest Reset Date, at least two of the
         Reference Banks provide such quotations, LIBOR shall equal the
         arithmetic mean of such quotations. If, on any Interest Reset Date,
         only one or none of the Reference Banks provide such a quotation, LIBOR
         shall be deemed to be the arithmetic mean of the offered quotations
         that at least two leading banks in the City of New York (as selected by
         the Calculation Agent) are quoting on the relevant Interest Reset Date
         for three-month U.S. Dollar deposits in Europe at approximately 11:00
         a.m. (London time) (in an amount determined by the Calculation Agent).
         As used herein, "Reference Banks" means four major banks in the London
         interbank market selected by the Calculation Agent.

                  If the Calculation Agent is required but is unable to
         determine a rate in accordance with at least one of the procedures
         provided above, LIBOR shall be LIBOR in effect on the previous Interest
         Reset Date (whether or not LIBOR for such period was in fact determined
         on such Interest Reset Date).

         The amount payable for any Interest Payment Period shall be computed on
the basis of a 360-day year and the actual number of days in such Interest
Payment Period. In the event that any date on which interest is payable on this
Debenture is not a Business Day, then payment of interest payable on such date
shall be made on the next succeeding day that is a Business Day except that, if
such Business Day is in the next succeeding calendar year, payment of such
interest will be made on the immediately preceding Business Day. The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date shall, be paid to the Person in whose name this Debenture
(or one or more Predecessor Debentures, as defined in said Indenture) is
registered as provided in the Indenture.

         The amount of interest for each day that a Debenture is outstanding
(the "Daily Interest Amount") will be calculated by dividing the Floating
Interest Rate in effect for such day by 360 and multiplying the result by the
principal amount of such Debenture.

         The Floating Interest Rate will in no event be higher than the maximum
rate permitted by the law of the State of Delaware, or, if higher, the law of
the United States of America.

         The principal of and the interest on this Debenture shall be payable at
or through the office or agency of the Trustee maintained for that purpose in
any coin or currency of the United States of America that at the time of payment
is legal tender for payment of public and private debts; provided, however, that
payment of interest may be made at the option of the Company by check mailed to
the registered holder at such address as shall appear in the Debenture Register.

                                      -4-
<PAGE>

Notwithstanding the foregoing, so long as the holder of this Debenture is the
Property Trustee, the payment of the principal of and interest on this Debenture
shall be made at such place and to such account as may be designated by the
Property Trustee.

         The Floating Interest Rate and amount of interest to be paid on the
Debentures for each Interest Payment Period will be determined by the
Calculation Agent. All calculations made by the Calculation Agent shall, in the
absence of manifest error, be conclusive for all purposes and binding on the
Company and the holders of this Debenture. In the event that any then acting
Calculation Agent shall be unable or unwilling to act, or that such Calculation
Agent shall fail duly to establish the Floating Interest Rate for any Interest
Payment Period, or that the Company proposes to remove such Calculation Agent,
or that the Calculation Agent proposes to terminate its service as Calculation
Agent, the Company shall appoint another Person, which is a bank, trust company,
investment banking firm or other financial institution, to act as the
Calculation Agent. The Calculation Agent shall certify the Floating Interest
Rate on each Interest Reset Date and shall provide a copy of such certification
to the Trustee under the Indenture and to the Property Trustee as soon as
practicable following each Interest Reset Date. The Trustee will provide written
notice of the Floating Interest Rate as certified by the Calculation Agent to
the holder of this Debenture within five Business Days following each Interest
Reset Date.

         Subject to the Company having received prior approval of the Federal
Reserve if then required under applicable capital guidelines, policies or
regulations of the Federal Reserve, the Company may redeem this Debenture prior
to the Stated Maturity in the manner and at the times set forth in the
Indenture.

         The payment by the Company of the principal and interest on the
indebtedness evidenced by this Debenture is, to the extent and in the manner
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all Senior Indebtedness. This Debenture is issued
subject to the provisions of the Indenture with respect thereto. Each holder of
this Debenture, by accepting the same, (a) agrees to and shall be bound by such
provisions; (b) authorizes and directs the Trustee on his or her behalf to take
such action as the Company advises the Trustee in writing is necessary or
appropriate to acknowledge or effectuate the subordination so provided; and (c)
appoints the Trustee his or her attorney-in-fact for any and all such purposes.
Each holder hereof, by his or her acceptance hereof, hereby waives all notice of
the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

         This Debenture shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

         Capitalized terms used and not defined in this Debenture shall have the
meanings assigned in the Indenture.

         The provisions of this Debenture are continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.

                        FLOATING RATE JUNIOR SUBORDINATED

                          DEFERRABLE INTEREST DEBENTURE

                                   (CONTINUED)

         This Debenture is one of the subordinated debentures of the Company
(herein sometimes referred to as the "Debentures"), specified in the Indenture,
all issued or to be issued under and pursuant to an Indenture effective as of
June 27, 2002 (the "Indenture") duly executed and delivered between the Company
and Wells Fargo Bank, National Association, as Trustee (the "Trustee"), to which
Indenture reference is hereby made for a description of the rights, limitations
of rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the holders of the Debentures and of the terms upon which the
Debentures are, and are to be, authenticated and delivered. The Debentures are
limited in aggregate principal amount as specified in the Indenture.

         Because of the occurrence and continuation of a Special Event, in
certain circumstances, this Debenture may become due and payable at the
principal amount together with any interest accrued thereon (the "Redemption
Price"). The Redemption Price shall be paid prior to 12:00 noon, Eastern
Standard Time, on the date of such redemption or at such earlier time as the
Company determines. The Company shall have the right as set forth in the
Indenture to redeem this Debenture at the option of the Company, without premium
or penalty, (i) in whole or in part, at any time on or after June 30, 2007 (an
"Optional Redemption"), or (ii) in whole, but not in part, at any time in
certain circumstances upon the occurrence of a Special Event, at a Redemption
Price equal to 103% of the principal amount plus any accrued but unpaid interest
hereon, to the date of such redemption. Any redemption pursuant to this
paragraph shall be made upon not less than 30 days' nor more than 60 days'
notice, at the Redemption Price. The Redemption Price shall be paid at the time
and in the name provided therefor in the Indenture. If the Debentures are only
partially redeemed by the Company pursuant to an Optional Redemption, the
Debentures shall be redeemed pro rata or by lot or by any other method utilized
by the Trustee as described in the Indenture.

         In the event of redemption of this Debenture in part only, a new
Debenture or Debentures for the unredeemed portion hereof shall be issued in the
name of the holder hereof upon the cancellation hereof. In case an Event of
Default, as defined in the Indenture, shall have occurred and be continuing, the
principal of all of the Debentures may be declared, and upon such declaration
shall become, due and payable, in the manner, with the effect and subject to the
conditions provided in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Debentures at the time Outstanding, as defined
in the Indenture, to execute supplemental indentures for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of the Indenture or of any supplemental indenture or of modifying in any manner
the rights of the holders of the Debentures; provided, however, that no such
supplemental indenture shall, except as provided in the Indenture (i) extend the
fixed maturity of

                                      -8-
<PAGE>

the Debentures, reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon, without the consent of the
holder of each Debenture so affected thereby; or (ii) reduce the aforesaid
percentage of Debentures, the holders of which are required to consent to any
such supplemental indenture, without the consent of the holders of each
Debenture then Outstanding and so affected thereby. The Indenture also contains
provisions permitting the holders of a majority in aggregate principal amount of
the Debentures at the time outstanding, on behalf of all of the holders of the
Debentures, to waive any past default in the performance of any of the covenants
contained in the Indenture, or established pursuant to the Indenture, and its
consequences, except a default in the payment of the principal of or interest on
any of the Debentures. Any such consent or waiver by the registered holder of
this Debenture (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such holder and upon all future holders and owners of this
Debenture and of any Debenture issued in exchange herefor or in place hereof
(whether by registration of transfer or otherwise), irrespective of whether or
not any notation of such consent or waiver is made upon this Debenture.

         No reference herein to the Indenture and no provision of this Debenture
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal and interest on this
Debenture at the time (subject to the Company's right to defer payment of
interest during an Extended Interest Payment Period as described herein) and
place and at the rate and in the money herein prescribed.

         As further described in the Indenture, the Company shall have the right
at any time during the term of the Debentures and from time to time to defer
payments of interest by extending the interest payment period of such Debentures
for up to 20 consecutive quarters (each, an "Extended Interest Payment Period"),
at the end of which period the Company shall pay all interest then accrued and
unpaid (together with interest thereon at the rate specified for the Debentures
to the extent that payment of such interest is enforceable under applicable
law). Before the termination of any such Extended Interest Payment Period, so
long as no Event of Default shall have occurred and be continuing, the Company
may further extend such Extended Interest Payment Period, provided that such
Extended Interest Payment Period together with all such further extensions
thereof shall not exceed 20 consecutive quarters, extend beyond the Stated
Maturity or end on a date other than an Interest Payment Date. At the
termination of any such Extended Interest Payment Period and upon the payment of
all accrued and unpaid interest and any additional amounts then due and subject
to the foregoing conditions, the Company may commence a new Extended Interest
Payment Period.

         As provided in the Indenture and subject to certain limitations therein
set forth, this Debenture is transferable by the registered holder hereof on the
Debenture Register at the office or agency of the Company designated for such
purpose upon surrender of this Debenture for registration of transfer
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company duly executed by the registered holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Debentures of
authorized denominations and for the same aggregate principal amount shall be
issued to the designated transferee or transferees. No service charge shall be
made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

                                      -9-
<PAGE>

         Prior to due presentment for registration of transfer of this
Debenture, the Company, the Trustee, any Paying Agent and the Debenture
Registrar may deem and treat the registered holder hereof as the absolute owner
hereof (whether or not this Debenture shall be overdue and notwithstanding any
notice of ownership or writing hereon made by anyone other than the Debenture
Registrar) for the purpose of receiving payment of or on account of the
principal hereof and interest due hereon and for all other purposes, and neither
the Company nor the Trustee nor any Paying Agent nor any Debenture Registrar
shall be affected by any notice to the contrary (by anyone other than the
Debenture Registrar).

         No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

         Subject to Section 2.3 of the Indenture, the Debentures are issuable
only in registered form without coupons in denominations of $1,000 and any
integral multiple thereof.

into the Company's Common Stock, $0.001 par value per share (the "COMMON
STOCK"), in accordance with the terms hereof. The unpaid principal balance
hereof shall automatically increase daily at the rate of 5% per annum from the
date of original issuance hereof (the "ISSUANCE DATE") until the same becomes
due and payable on the Maturity Date, or such earlier date upon acceleration or
by conversion or redemption in accordance with the terms hereof or of the other
Agreements. Such principal accretion under this Note shall occur daily
commencing on the Issuance Date and shall be computed on the basis of a 360-day
year and shall be payable in accordance with Section 2 hereof. Notwithstanding
anything contained herein, this Note shall bear interest on the due and unpaid
Principal Amount from and after the occurrence and during the continuance of an
Event of Default pursuant to Section 5(a), at the rate (the "DEFAULT RATE")
equal to the lower of eighteen percent (18%) per annum or the highest rate
permitted by law. Unless otherwise agreed or required by applicable law,
payments will be applied first to any unpaid collection costs, then to unpaid
default interest and Accreted Amounts, and fees and any remaining amount to
principal.

         All payments of principal (including accreted principal) and default
interest on this Note which are not paid in shares of Common Stock as permitted

time to time designate by written notice in accordance with the provisions of
this Note or by Company check. This Note may not be prepaid in whole or in part

<PAGE>

         "PER SHARE SELLING PRICE" shall include the amount actually paid by
third parties for each share of Common Stock in a sale or issuance by the
Company. In the event a fee is paid by the Company in connection with such
transaction directly or indirectly to such third party or its affiliates, any
such fee shall be deducted from the selling price pro rata to all shares sold in
the transaction to arrive at the Per Share Selling Price. A sale of shares of
Common Stock shall include the sale or issuance of Convertible Securities, and
in such circumstances the Per Share Selling Price of the Common Stock covered
thereby shall also include the exercise, exchange or conversion price thereof
(in addition to the consideration received by the Company upon such sale or
issuance less the fee amount as provided above). In case of any such security
issued in a Variable Rate Transaction, the Per Share Selling Price shall be
deemed to be the lowest conversion or exercise price at which such securities
are converted or exercised or might have been converted or exercised, or the
lowest adjustment price, as the case may be, over the life of such securities.
If shares are issued for a consideration other than cash, the Per Share Selling
Price shall be the fair value of such consideration as determined in good faith
by independent certified public accountants mutually acceptable to the Company
and the Holder. In the event the Company directly or indirectly effectively
reduces the conversion, exercise or exchange price for any Convertible
Securities which are currently outstanding, then the Per Share Selling Price
shall equal such effectively reduced conversion, exercise or exchange price.

such Prepayment Rate is being determined.

         "PRINCIPAL AMOUNT" shall refer to the sum of (i) the original principal

         "TRADING DAY" shall mean a day on which there is trading on the
Principal Market.

for the Common Stock on the Principal Market on any particular Trading Day
during the period beginning at 9:30 a.m., New York City Time (or such other time

ending at 4:00 p.m., New York City Time (or such other time as the Principal
Market publicly announces is the official close of trading), as reported by
Bloomberg through its "Volume at Price" functions or, if the foregoing does not
apply, the dollar volume-weighted average price of such security in the
over-the-counter market on the

                                       4
<PAGE>

electronic bulletin board for such security during the period beginning at 9:30
a.m., New York City Time (or such other time as the Principal Market publicly
announces is the official open of trading), and ending at 4:00 p.m., New York
City Time (or such other time as the Principal Market publicly announces is the
official close of trading), as reported by Bloomberg, or, if no dollar
volume-weighted average price is reported for such security by Bloomberg for
such hours, the average of the highest closing bid price and the lowest closing
ask price of any of the market makers for such security as reported in the "pink
sheets" by the National Quotation Bureau, Inc. If the VWAP cannot be calculated
for such security on such date on any of the foregoing bases, the VWAP of such
security on such date shall be the fair market value as mutually determined by
the Company and the holders of at least a majority of the principal amount of
the Notes then outstanding. All such determinations of VWAP shall to be
appropriately and equitably adjusted in accordance with the provisions set forth
herein for any stock dividend, stock split, stock combination or other similar
transaction occurring during any period used to determine the Market Price (or
other period utilizing VWAPs).

         SECTION 2. ACCRETION.

                  (a) Payment Dates. On October 1 and April 1 of each year (each
an "ACCRETION PAYMENT DATE") after the Issuance Date, the Company shall either
pay the dollar amount accrued and accreted to the principal amount hereunder
since the prior Accretion Payment Date (or Issuance Date if no such Accretion
Payment Date has yet to occur) ("ACCRETED AMOUNT") or effect the automatic
conversion of such Accreted Amount as provided in this Section 2.

                  (b) Payment or Automatic Conversion. Subject to the terms
hereof, the Company shall either (i) pay the Accreted Amount in full in cash on
each Accretion Payment Date or (ii) effect an automatic conversion of such
Accreted Amount into shares of Common Stock in accordance with the terms hereof,
but not both, at the Company's option. Prior to each Accretion Payment Date the
Company shall deliver to all the holders of Notes a written irrevocable notice
electing to pay such Accreted Amount in cash or effect such automatic conversion
on such Accretion Payment Date. Such notice shall be delivered at least five (5)
days prior to the applicable Accretion Payment Date but no more than twenty (20)
days prior to such Accretion Payment Date. If such notice is not delivered
within the prescribed period set forth in the preceding sentence, then the
Accreted Amount shall be paid in cash. If the Company elects to pay any Accreted
Amount in cash on an Accretion Payment Date, then on such date the Company shall
pay to the Holder an amount equal to the Accreted Amount due in satisfaction of
such obligation. If the Company elects to effect an automatic conversion of such
Accreted Amount into shares of Common Stock, the number of such shares to be
issued for such Accretion Payment Date shall be the number determined by
dividing (x) the Accreted Amount due, by (y) the Market Price as of such
Accretion Payment Date. Such shares shall be issued and delivered within three
(3) Trading Days following such Accretion Payment Date and shall be duly
authorized, validly issued, fully paid, non-assessable and free and clear of all
encumbrances, restrictions and legends. If any Holder does not receive the
requisite number of shares of Common Stock in the form required above within
such three Trading Day period, the Holder shall have the option of either (a)
requiring the Company to issue and deliver all or a portion of such shares or
(b) canceling such election to effect such automatic conversion of the Accreted
Amount (in whole or in part), in which case the Company shall immediately pay in
cash the Accreted Amount due hereunder or such portion as the Holder specifies
is to be paid in cash instead of being converted. Except as otherwise provided
in this Section 2, all holders of

                                       5
<PAGE>

Notes must be treated equally with respect to such payment and conversion of
Accreted Amounts. Any conversion of the Accreted Amount hereunder into shares of
Common Stock pursuant to the terms hereof shall constitute and be deemed a
conversion of such portion of the Principal Amount of this Note for all purposes
under this Note and the other Agreements (except that such conversion shall be
at the Market Price and except as otherwise provided herein).

                  (c) Limitations to Automatic Conversion into Common Stock.
Notwithstanding anything to the contrary herein, the Company shall be prohibited
from exercising its right to effect an automatic conversion of any Accreted
Amount hereunder (and must deliver cash in respect thereof) on the applicable
Accretion Payment Date (1) if at any time within ten (10) Trading Days prior to
the Accretion Payment Date there fails to exist Effective Registration or an
Event of Default hereunder exists or occurs, unless otherwise waived in writing
by the Holder in whole or in part at the Holder's option, and (2) to the extent,
and only to the extent, that such conversion into shares of Common Stock would
result in the Holder hereof exceeding the limitations contained in Section 3(i)
below or the Cap Regulations.

         SECTION 3. CONVERSION.

                  (a) Conversion Right. Subject to the terms hereof and
restrictions and limitations contained herein, the Holder shall have the right,
at such Holder's option, at any time and from time to time to convert the
outstanding Principal Amount under this Note in whole or in part by delivering
to the Company a fully executed notice of conversion in the form of conversion
notice attached hereto as Exhibit A (the "CONVERSION NOTICE"), which may be
transmitted by facsimile. Notwithstanding anything to the contrary herein, this
Note and the outstanding Principal Amount hereunder shall not be convertible
into Common Stock to the extent that such conversion would result in the Holder
hereof exceeding the limitations contained in, or otherwise violating the
provisions of, Section 3(i) below or the Cap Regulations.

                  (b) Common Stock Issuance Upon Conversion.

                           (i) Conversion Date Procedures. Upon conversion of
this Note pursuant to Section 3(a) above, the outstanding Principal Amount
hereunder shall be converted into such number of fully paid, validly issued and
non-assessable shares of Common Stock, free of any liens, claims and
encumbrances, as is determined by dividing the outstanding Principal Amount
being converted by the then applicable Conversion Price. The date of any
Conversion Notice hereunder shall be referred to herein as the "CONVERSION
DATE". If a conversion under this Note cannot be effected in full for any
reason, or if the Holder is converting less than all of the outstanding
Principal Amount hereunder pursuant to a Conversion Notice, the Company shall
promptly deliver to the Holder (but no later than five Trading Days after the
Conversion Date) a Note for such outstanding Principal Amount as has not been
converted if this Note has been surrendered to the Company for partial
conversion. The Holder shall not be required to physically surrender this Note
to the Company upon any conversion hereunder unless the full outstanding
Principal Amount represented by this Note is being converted. The Holder and the
Company shall maintain records showing the outstanding Principal Amount so
converted and the dates of such conversions or shall use such other method,
reasonably satisfactory to the Holder and the Company, so as not to require
physical surrender of this Note upon each such conversion.

                                       6
<PAGE>

                           (ii) Stock Certificates or DWAC. The Company will
deliver to the Holder not later than three (3) Trading Days after the Conversion
Date, a certificate or certificates, which shall be free of restrictive legends
and trading restrictions if the Registration Statement has been declared
effective, representing the number of shares of Common Stock being acquired upon
the conversion of this Note. In lieu of delivering physical certificates
representing the shares of Common Stock issuable upon conversion of this Note,
provided the Company's transfer agent is participating in the Depository Trust
Company ("DTC") Fast Automated Securities Transfer ("FAST") program, upon
request of the Holder, the Company shall use commercially reasonable efforts to
cause its transfer agent to electronically transmit such shares issuable upon
conversion to the Holder (or its designee), by crediting the account of the
Holder's (or such designee's) prime broker with DTC through its Deposit
Withdrawal Agent Commission system (provided that the same time periods herein
as for stock certificates shall apply). If in the case of any conversion
hereunder, such certificate or certificates are not delivered to or as directed
by the Holder by the fifth Trading Day after the Conversion Date, the Holder
shall be entitled by written notice to the Company at any time on or before its
receipt of such certificate or certificates thereafter, to rescind such
conversion, in which event the Company shall immediately return this Note
tendered for conversion. If the conversion has not been rescinded in accordance
with the previous sentence and the Company fails to deliver to the Holder such
certificate or certificates (or shares through DTC) pursuant to this Section
3(b) (free of any restrictions on transfer or legends, if such shares have been
registered) in accordance herewith, prior to the seventh Trading Day after the
Conversion Date, the Company shall pay to the Holder, in cash, an amount equal
to 2% of the Principal Amount per month until such delivery takes place.

                  (c) Conversion Price Adjustments.

                           (i) Stock Dividends, Splits and Combinations. If the
Company or any of its subsidiaries, at any time while the Notes are outstanding
(A) shall pay a stock dividend or otherwise make a distribution or distributions
on any equity securities (including instruments or securities convertible into
or exchangeable for such equity securities) in shares of Common Stock, (B)
subdivide outstanding Common Stock into a larger number of shares, or (C)
combine outstanding Common Stock into a smaller number of shares, then each
Affected Conversion Price (as defined below) shall be multiplied by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
before such event and the denominator of which shall be the number of shares of
Common Stock outstanding after such event. Any adjustment made pursuant to this
Section 3(c)(i) shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a
subdivision or combination.

                  As used in this Note, the Affected Conversion Prices (each an
"AFFECTED CONVERSION PRICE") shall refer to: (i) the Conversion Price; and (ii)
each reported VWAP occurring on any Trading Day included in the period used for
determining the Market Price, which Trading Day occurred before the record date
in the case of events referred to in clause (A) of this subparagraph 3(c)(i) and
before the effective date in the case of the events referred to in clauses (B)
and (C) of this subparagraph 3(c)(i).

                                       7
<PAGE>

                           (ii) Distributions. If the Company or any of its
subsidiaries, at any time while the Notes are outstanding, shall distribute to
all holders of Common Stock evidences of its indebtedness or assets or cash or
rights or warrants to subscribe for or purchase any security of the Company or
any of its subsidiaries (excluding those referred to in Section 3(c)(i) above),
then concurrently with such distributions to holders of Common Stock, the
Company shall distribute to holders of the Notes the amount of such
indebtedness, assets, cash or rights or warrants which the holders of Notes
would have received had all their Notes then held been converted into Common
Stock at the applicable Prepayment Rate immediately prior to the record date for
such distribution.

                           (iii) Common Stock Issuances. In the event that the
Company or any of its subsidiaries (A) issues or sells any Common Stock or
Convertible Securities or (B) directly or indirectly effectively reduces the
conversion, exercise or exchange price for any Convertible Securities which are
currently outstanding, at or to an effective Per Share Selling Price which is
less than the greater of (I) the closing sale price per share of the Common
Stock on the Principal Market on the Trading Day next preceding such issue or
sale or, in the case of issuances to holders of its Common Stock, the date fixed
for the determination of stockholders entitled to receive such warrants, rights,
or options ("FAIR MARKET PRICE"), or (II) the Conversion Price, then in each
such case the Conversion Price in effect immediately prior to such issue or sale
or record date, as applicable, shall be automatically reduced effective
concurrently with such issue or sale to an amount determined by multiplying the
Conversion Price then in effect by a fraction, (x) the numerator of which shall
be the sum of (1) the number of shares of Common Stock outstanding immediately
prior to such issue or sale, plus (2) the number of shares of Common Stock which
the aggregate consideration received by the Company for such additional shares
would purchase at such Fair Market Price or Conversion Price, as the case may
be, and (y) the denominator of which shall be the number of shares of Common
Stock of the Company outstanding immediately after such issue or sale. The
foregoing provision shall not apply to any issuances or sales of Common Stock or
Convertible Securities (i) pursuant to any Convertible Securities currently
outstanding on the date hereof in accordance with the terms of such Convertible
Securities in effect on the date hereof, (ii) pursuant to the Notes or Warrants,
(iii) pursuant to any capital raising which is not a Variable Rate Transaction
and which is consummated on or prior to September 30, 2002, or (iv) to any
officer, director, employee or Consultant (as defined below) of the Company
pursuant to a bona fide option or equity incentive plan duly adopted by the
Company, provided that any such issuances or sales to Consultants must be
reasonable consideration for the services rendered by such Consultants and shall
not exceed more than $1 million in market value to all Consultants in the
aggregate under any circumstances. "Consultant" shall mean any natural person
providing bona fide services to the Company which are not in connection with the
offer or sale of securities in a capital raising transaction and which do not
directly or indirectly promote or maintain a market for the Company's
securities. The Company shall give to the Holder written notice of any such sale
of Common Stock within 24 hours of the closing of any such sale and shall within
such 24 hour period issue a press release announcing such sale if such sale is a
material event for, or otherwise material to, the Company.

                           (iv) Rounding of Adjustments. All calculations under
this Section 3 or Section 2 shall be made to the nearest cent or the nearest
1/100th of a share, as the case may be.

                                       8
<PAGE>

                           (v) Notice of Adjustments. Whenever any Affected
Conversion Price is adjusted pursuant to Section 3(c)(i), (ii) or (iii) above,
the Company shall promptly deliver to each holder of the Notes, a notice setting
forth the Affected Conversion Price after such adjustment and setting forth a
brief statement of the facts requiring such adjustment, provided that any
failure to so provide such notice shall not affect the automatic adjustment
hereunder.

                           (vi) Change in Control Transactions. In case of any
Change in Control Transaction, the Holder shall have the right thereafter to, at
its option, (A) convert this Note, in whole or in part, at the then applicable
Conversion Price into the shares of stock and other securities, cash and/or
property receivable upon or deemed to be held by holders of Common Stock
following such Change in Control Transaction, and the Holder shall be entitled
upon such event to receive such amount of securities, cash or property as the
shares of the Common Stock of the Company into which this Note could have been
converted immediately prior to such Change in Control Transaction would have
been entitled if such conversion were permitted, subject to such further
applicable adjustments set forth in this Section 3 or (B) require the Company or
its successor to redeem this Note, in whole or in part, at a redemption price
equal to 110% of the outstanding Principal Amount being redeemed. The terms of
any such Change in Control Transaction shall include such terms so as to
continue to give to the Holders the right to receive the amount of securities,
cash and/or property upon any conversion or redemption following such Change in
Control Transaction to which a holder of the number of shares of Common Stock
deliverable upon such conversion would have been entitled in such Change in
Control Transaction, and default interest and Accreted Amounts payable hereunder
shall be in cash or such new securities and/or property, at the Holder's option.
This provision shall similarly apply to successive reclassifications,
consolidations, mergers, sales, transfers or share exchanges.

                           (vii) Notice of Certain Events. If:

                                 A.  the Company shall declare a dividend (or
                                     any other distribution) on its Common
                                     Stock; or

                                 B.  the Company shall declare a special
                                     nonrecurring cash dividend on or a
                                     redemption of its Common Stock; or

                                 C.  the Company shall authorize the granting to
                                     all holders of the Common Stock rights or
                                     warrants to subscribe for or purchase any
                                     shares of capital stock of any class or of
                                     any rights; or

                                 D.  the approval of any stockholders of the
                                     Company shall be required in connection
                                     with any reclassification of the Common
                                     Stock of the Company, any consolidation or
                                     merger to which the Company is a party, any
                                     sale or transfer of all or substantially
                                     all of the assets of the Company, or any
                                     compulsory share of exchange whereby the
                                     Common Stock is converted into other
                                     securities, cash or property; or

                                 E.  the Company shall authorize the voluntary
                                     or involuntary dissolution, liquidation or
                                     winding up of the affairs of the

                                       9
<PAGE>

                                     Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of this Note, and shall cause to be mailed to the
Holder at its last address as it shall appear upon the books of the Company, on
or prior to the date notice to the Company's stockholders generally is given, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution, redemption, rights or warrants, or if a record is
not to be taken, the date as of which the holders of Common Stock of record to
be entitled to such dividend, distributions, redemption, rights or warrants are
to be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange.

                  (d) Reservation and Issuance of Underlying Securities. The
Company covenants that it will at all times reserve and keep available out of
its authorized and unissued Common Stock solely for the purpose of issuance upon
conversion of this Note (including repayments in stock), free from preemptive
rights or any other actual contingent purchase rights of persons other than the
holders of the Notes, not less than such number of shares of Common Stock as
shall (subject to any additional requirements of the Company as to reservation
of such shares set forth in the Purchase Agreement) be issuable (taking into
account the adjustments under this Section 3 but without regard to any ownership
limitations contained herein) upon the conversion of this Note hereunder in
Common Stock (including conversion of Accreted Amounts or Prepayment Amounts
into Common Stock). The Company covenants that all shares of Common Stock that
shall be so issuable shall, upon issue, be duly authorized, validly issued,
fully paid, nonassessable.

                  (e) No Fractions. Upon a conversion hereunder the Company
shall not be required to issue stock certificates representing fractions of
shares of Common Stock, but may if otherwise permitted, make a cash payment in
respect of any final fraction of a share based on the closing price of a share
of Common Stock at such time. If the Company elects not, or is unable, to make
such a cash payment, the Holder shall be entitled to receive, in lieu of the
final fraction of a share, one whole share of Common Stock.

                  (f) Charges, Taxes and Expenses. Issuance of certificates for
shares of Common Stock upon the conversion of this Note (including conversion of
Accreted Amounts and Prepayment Amounts) shall be made without charge to the
holder hereof for any issue or transfer tax or other incidental expense in
respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the Holder or in such name or names as may be directed by the Holder;
provided, however, that in the event certificates for shares of Common Stock are
to be issued in a name other than the name of the Holder, this Note when
surrendered for conversion shall be accompanied by an assignment form; and
provided further, that the Company shall not be required to pay any tax or taxes
which may be payable in respect of any such transfer.

                  (g) Cancellation. After all of the Principal Amount (including
accrued but unpaid interest and Accreted Amounts and default payments at any
time owed on this Note) have been paid in full or converted into Common Stock,
this Note shall automatically be deemed

                                       10
<PAGE>

canceled and the Holder shall promptly surrender the Note to the Company at the
Company's principal executive offices.

                  (h) Notices Procedures. Any and all notices or other
communications or deliveries to be provided by the Holder hereunder, including,
without limitation, any Conversion Notice, shall be in writing and delivered
personally, by confirmed facsimile, or by a nationally recognized overnight
courier service to the Company at the facsimile telephone number or address of
the principal place of business of the Company as set forth in the Purchase
Agreement. Any and all notices or other communications or deliveries to be
provided by the Company hereunder shall be in writing and delivered personally,
by facsimile, or by a nationally recognized overnight courier service addressed
to the Holder at the facsimile telephone number or address of the Holder
appearing on the books of the Company, or if no such facsimile telephone number
or address appears, at the principal place of business of the Holder. Any notice
or other communication or deliveries hereunder shall be deemed delivered (i)
upon receipt, when delivered personally, (ii) when sent by facsimile, upon
receipt if received on a Business Day prior to 5:00 p.m. (Eastern Time), or on
the first Business Day following such receipt if received on a Business Day
after 5:00 p.m. (Eastern Time) or (iii) upon receipt, when deposited with a
nationally recognized overnight courier service.

                  (i) Beneficial Ownership Limitation. Notwithstanding anything
to the contrary contained herein, the number of shares of Common Stock that may
be acquired by the Holder upon conversion pursuant to the terms hereof
(including conversion of Accreted Amounts and Prepayment Amounts into Common
Stock hereunder) shall not exceed a number that, when added to the total number
of shares of Common Stock deemed beneficially owned by such Holder (other than
by virtue of the ownership of securities or rights to acquire securities
(including the Notes and Warrants) that have limitations on the Holder's right
to convert, exercise or purchase similar to the limitation set forth herein),
together with all shares of Common Stock deemed beneficially owned at such time
(other than by virtue of the ownership of securities or rights to acquire
securities that have limitations on the right to convert, exercise or purchase
similar to the limitation set forth herein) by the holder's "affiliates" at such
time (as defined in Rule 144 of the Securities Act) ("AGGREGATION PARTIES") that
would be aggregated for purposes of determining whether a group under Section
13(d) of the Exchange Act exists, would exceed 9.9% of the total issued and
outstanding shares of the Common Stock (the "RESTRICTED OWNERSHIP PERCENTAGE").
Each holder shall have the right (x) at any time and from time to time to reduce
its Restricted Ownership Percentage immediately upon notice to the Company and
(y) (subject to waiver) at any time and from time to time, to increase its
Restricted Ownership Percentage immediately in the event of the announcement as
pending or planned, of a Change in Control Transaction. The Company's obligation
to issue shares of Common Stock which would exceed such limits referred to in
this Section 3(i) shall be suspended to the extent necessary until such time, if
any, as shares of Common Stock may be issued in compliance with such
restrictions.

         SECTION 4. PREPAYMENTS AND REDEMPTION.

                  (a) Monthly Prepayment Right.

                           (i) Company Prepayment Right. Subject to the terms
and conditions herein (including without limitation Section 4(c) below), the
Company shall have the right to

                                       11
<PAGE>

prepay up to $250,000 in outstanding principal hereunder, together with all
Accreted Amounts accrued thereon through the date of payment (collectively each
a "PREPAYMENT AMOUNT"), in any calendar month either in cash or by automatically
converting such amount into shares of Common Stock, or a combination thereof at
the Company's option, provided that the Company may not exercise such right, or
deliver a Prepayment Election Notice (as defined below), with respect to this
Note during a Notice Blockage Period (as defined in subsection 4(a)(iv) below).

                           (ii) Exercise Procedure. In order to exercise such
prepayment right, the Company shall deliver to all the holders of Notes (other
than during a Notice Blockage Period to Holders which have elected a Notice
Blockage Period) a written irrevocable notice electing to make such prepayment
("PREPAYMENT ELECTION NOTICE"), specifying the dollar amount of the Prepayment
Amount to be converted into Common Stock and the dollar amount of the Prepayment
Amount to be prepaid in cash. Such Prepayment Payment Notice must be delivered
on or prior to the fifteenth (15th) day of any calendar month, and the
prepayment and/or conversion corresponding to such Prepayment Election Notice
shall be paid and/or effected on the first Trading Day of the following calendar
month (and not before) (the "PREPAYMENT DATE", and the period from the date of
such Prepayment Election Notice until the Prepayment Date shall be hereinafter
referred to as the "PREPAYMENT NOTICE PERIOD"). Except as otherwise provided in
this Section 4, all holders of Notes must be treated equally with respect to
such prepayments and conversions.

                           (iii) Payment/Conversion. On the Prepayment Date, (x)
the Company shall pay to the Holder in cash the portion of the Prepayment Amount
elected to be prepaid in cash in the Prepayment Election Notice and (y) the
portion of the Prepayment Amount elected to be converted into stock in the
Prepayment Election Notice shall be automatically converted into Common Stock in
accordance with the terms hereof. If the Holder does not receive the requisite
amount of cash in connection with such prepayment within three (3) Trading Days
following the Prepayment Date, such amount shall bear interest hereunder at the
Default Rate. To the extent the Company elects to make any such prepayment by
converting all or a portion of the Prepayment Amount into shares of Common Stock
pursuant to this Section 4(a), the number of such shares to be issued upon such
conversion for such Prepayment Date shall be the number determined by dividing
(x) the portion of the Prepayment Amount to be converted into Common Stock, by
(y) the Prepayment Rate as of such Prepayment Date. Such shares shall be issued
and delivered within three (3) Trading Days following such Prepayment Date and
shall be duly authorized, validly issued, fully paid, non-assessable and free
and clear of all encumbrances, restrictions and legends. If any Holder does not
receive the requisite number of shares of Common Stock in the form required
above within such three Trading Day period, the Holder shall have the option of
either (a) requiring the Company to issue and deliver all or a portion of such
shares, (b) canceling such election to prepay any portion of this Note, or (c)
requiring the Company to prepay in cash all or a portion of the Prepayment
Amount which had been elected for conversion into Common Stock. Notwithstanding
anything to the contrary herein, the Company shall be prohibited from exercising
its right to convert any portion of the Prepayment Amount into shares of Common
Stock on the applicable Prepayment Date to the extent, and only to the extent,
that such conversion into shares of Common Stock would result in the Holder
hereof exceeding the limitations contained in Section 3(i) above or the Cap
Regulations. Any conversion hereunder into shares of Common Stock pursuant to
the terms hereof shall constitute and be deemed a conversion of such portion of
the Principal Amount of this Note for all

                                       12
<PAGE>

purposes under this Note and the other Agreements (except that such conversion
shall be at the Prepayment Rate and except as otherwise provided herein).

                           (iv) Notice Blockage Period. At any time on any one
occasion, the Holder may elect to prohibit any prepayments (whether in cash or
by conversion of a Prepayment Amount) pursuant to this Section 4(a) above for a
period of one (1) year ("NOTICE BLOCKAGE PERIOD") by delivering a written notice
to the Company specifying the commencement date of such Notice Blockage Period,
provided, however, that if prior to delivery of such notice the Company has
already delivered a Prepayment Election Notice but the applicable Prepayment
Date has not yet occurred, then the 1-year Notice Blockage Period shall not
commence until the end of the full calendar month following such Prepayment
Election Notice.

                  (b) Redemption Right. Subject to the terms and conditions
herein (including without limitation Section 4(c) below), in the event that the
Company enters into an agreement with a nationally recognized investment banking
firm ("UNDERWRITER") to effect a firm commitment registered underwritten public
offering of Common Stock (excluding equity-line transactions and transactions
with affiliates) yielding proceeds for the Company in excess of $10 million
("OFFERING") and such Underwriter requires that the Company redeem all or part
of the outstanding Notes in full as a condition for consummating such Offering,
then the Company shall have the right to redeem for cash such portion of the
outstanding Notes as the Underwriter requires to be redeemed at a redemption
price equal to (a) the Principal Amount outstanding of the Notes (which includes
default interest and Accreted Amounts accrued hereunder through the redemption
date), plus (b) the dollar amount of default interest and Accreted Amounts (in
cash) which would have accrued and accreted on the outstanding Notes being
redeemed from the redemption date through the originally scheduled Maturity Date
had such Notes remained outstanding until the Maturity Date. In order to
exercise such redemption right, the Company shall deliver to all holders of
Notes an irrevocable redemption notice ("REDEMPTION NOTICE") electing to so
redeem at least 30 days prior to any such redemption (the period between such
Redemption Notice and such actual redemption hereinafter referred to as the
"REDEMPTION NOTICE PERIOD"), provided that the Company may not deliver such
notice if there is not Effective Registration at such time. The redemption date
shall occur no earlier than the closing of the Offering and no later than
fifteen (15) days following the closing of the Offering. If the Offering is not
consummated as contemplated herein, the Company shall not have the right to
redeem the Notes in connection with such Offering and the applicable Redemption
Notice shall be deemed null and void and of no further force or effect. For
clarification purposes, the Holder shall have the right to convert any or all of
this Note at any time and from time to time during the Redemption Notice Period.

                  (c) No Effective Registration. Notwithstanding anything to the
contrary herein, the Company shall be prohibited from exercising its right to
prepay or redeem this Note pursuant to Section 4(a) or 4(b) above if at any time
during the Prepayment Notice Period or Redemption Notice Period, as the case may
be, there fails to exist Effective Registration or an Event of Default hereunder
exists or occurs, unless otherwise waived in writing by the Holder in whole or
in part at the Holder's option. If there fails to exist Effective Registration
or an Event of Default hereunder exists or occurs after the delivery a
Prepayment Election Notice or Redemption Notice, as the case may be, then such
Prepayment Election Notice or Redemption Notice shall be deemed null and void
and of no force or effect.

         SECTION 5. DEFAULTS AND REMEDIES.

                  (a) Events of Default. An "EVENT OF DEFAULT" is:

                           (i) a default in payment of the Principal Amount
under any of the Notes on or after the date such payment is due, which default
continues for five (5) Business Days after written notice of such non-payment
has been received by the Company, or a default in payment of accrued but unpaid
Accreted Amounts under any of the Notes on or after the date such payment is
due, which default continues for fifteen (15) days after written notice of such
non-payment has been received by the Company;

                           (ii) a default in the timely issuance of Underlying
Shares upon and in accordance with terms hereof, which default continues for
five (5) Business Days after the Company has received written notice informing
the Company that it has failed to issue shares or deliver stock certificates
within the third Trading Day following the Conversion Date;

                           (iii) failure by the Company or the Operating
Subsidiary for thirty (30) days after written notice has been received by the
Company to comply with any material provision of any of the Notes, the Purchase
Agreement, the Registration Rights Agreement, the Subsidiary Guaranty, the
Mortgage or the Warrants or any other agreement between the Holder and the
Company (including without limitation the failure to issue the requisite number
of shares of Common Stock upon conversion hereof and the failure to redeem Notes
upon the Holder's request following a Change in Control Transaction pursuant to
this Note);

                           (iv) any representation, warranty or statement made
or furnished by the Company or any of its subsidiaries to the Holder (or any
collateral agent on behalf of the Holder) under the Purchase Agreement,
Registration Rights Agreement, Subsidiary Guaranty, Mortgage or Warrants, or any
other agreement between the Holder and the Company or any certificate of
schedule required thereby, is false or misleading in any material respect when
made;

                           (v) the Subsidiary Guaranty or Mortgage ceases to be
in full force and effect (including failure to create a valid and perfected
first priority lien on and security interest in the Mortgaged Property (as
defined in the Mortgage)) at any time for any reason;

                           (vi) any material adverse change in the condition,
value or operation of a material portion of the Mortgaged Property;

                           (vii) any acceleration prior to maturity of, any
mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any indebtedness for money borrowed by the
Company or any of its subsidiaries for in excess of $2 million or for money
borrowed the repayment of which is guaranteed by the Company or any of its
subsidiaries for in excess of $2 million, whether such indebtedness or guarantee
now exists or shall be created hereafter;

                           (viii) the dissolution or termination of the Company

or the Operating Subsidiary as a going concern; or

                           (ix) if the Company is subject to any Bankruptcy
Event.

                                       14
<PAGE>

                  (b) Remedies. If an Event of Default occurs and is continuing
with respect to any of the Notes, the Holder may declare all of the then
outstanding Principal Amount of this Note and all other Notes held by the
Holder, including any default interest and Accreted Amounts due thereon, to be
due and payable immediately, except that in the case of an Event of Default
arising from events described in clauses (viii) through (ix) of Section 5(a),
this Note shall become due and payable without further action or notice. In the
event of such acceleration, the amount due and owing to the Holder shall be the
greater of (1) 120% of the outstanding Principal Amount of the Notes held by the
Holder (plus all accrued and unpaid default interest and Accreted Amounts, if
any) and (2) the product of (A) the highest closing price for the five (5)
Trading Days immediately preceding the Holder's acceleration and (B) the
outstanding Principal Amount divided by the lower of the Conversion Price and
the Prepayment Rate. In either case the Company shall pay interest on such
amount in cash at the Default Rate to the Holder if such amount is not paid
within 7 days of Holder's request. The remedies under this Note shall be
cumulative.

         SECTION 6. SECURITY AND GUARANTY. The Company's and the Operating
Subsidiary's obligations under this Note and the other Agreements are secured by
Mortgaged Property (as defined in the Mortgage) pursuant to the terms of the
Mortgage and the obligations under this Note are guaranteed by the Operating
Subsidiary pursuant to the Subsidiary Guaranty.

         SECTION 7. GENERAL.

                  (a) Payment of Expenses. The Company agrees to pay all
reasonable charges and expenses, including attorneys' fees and expenses, which
may be incurred by the Holder in successfully enforcing this Note and/or
collecting any amount due under this Note. This includes, without limitation and
subject to any limits under applicable law, Holder's reasonable collection costs
under Section 5(b) and Holder's reasonable attorneys' fees and legal expenses
whether or not there is a lawsuit, including reasonable attorneys' fees and
legal expenses for bankruptcy proceedings (including efforts to modify or vacate
any automatic stay or injunction), appeals and any anticipated post-judgment
collection services. If not prohibited by applicable law, the Company also will
pay any court costs, in addition to all other sums provided by law.

                  (b) Savings Clause. In case any provision of this Note is held
by a court of competent jurisdiction to be excessive in scope or otherwise
invalid or unenforceable, such provision shall be adjusted rather than voided,
if possible, so that it is enforceable to the maximum extent possible, and the
validity and enforceability of the remaining provisions of this Note will not in
any way be affected or impaired thereby. In no event shall the amount of
interest paid or converted hereunder (which for this purpose shall include all
default interest, all Accreted Amounts and all other consideration or charges
deemed to be interest) exceed the maximum rate of interest on the unpaid
principal balance hereof allowable by applicable law. If any sum is collected in
excess of the applicable maximum rate, the excess collected shall be applied to
reduce the principal debt. If the interest actually collected hereunder is still
in excess of the applicable maximum rate, the interest rate shall be reduced so
as not to exceed the maximum allowable under law.

                  (c) Amendment. Neither this Note nor any term hereof may be
amended, waived, discharged or terminated other than by a written instrument
signed by the Company and the Holder.

                                       15
<PAGE>

                  (d) Assignment, Etc. The Holder may assign or transfer this
Note to any transferee only with the prior written consent of the Company, which
may not be unreasonably withheld or delayed, provided that (i) the Holder may
assign or transfer this Note to any of such Holder's Affiliates without the
consent of the Company and (ii) upon any Event of Default, the Holder may assign
or transfer this Note without the consent of the Company, provided in each case
that such Affiliate, transferee or assignee acknowledges in writing to the
Company that the representations and warranties contained in Section 5 of the
Purchase Agreement shall apply to such Affiliate, transferee or assignee. The
Holder shall notify the Company of any such assignment or transfer promptly.
This Note shall be binding upon the Company and its successors and shall inure
to the benefit of the Holder and its successors and permitted assigns.

                  (e) Waiver.

                           (i) No failure on the part of the Holder to exercise,
and no delay in exercising any right, remedy or power hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise by the Holder of any
right, remedy or power hereunder preclude any other or future exercise of any
other right, remedy or power. Each and every right, remedy or power hereby
granted to the Holder or allowed it by law or other agreement shall be
cumulative and not exclusive of any other, and may be exercised by the Holder
from time to time. The release of any party liable under this Note shall not
operate to release any other party liable under this Note.

                           (ii) Except as otherwise provided herein, the Company
and any other person who signs, guarantees or endorses this Note, to the extent
allowed by law, hereby expressly waives demand and presentment for payment,
notice of nonpayment, protest, notice of protest, notice of dishonor, notice of
acceleration or intent to accelerate, all other notices whatsoever and bringing
of suit and diligence in taking any action to collect amounts called for
hereunder, and will be directly and primarily liable for the payment of all sums
owing and to be owing hereunder, regardless of and without any notice,
diligence, act or omission as or with respect to the collection of any amount
called for hereunder.

                  (f) Governing Law; Jurisdiction.

                           (i) Governing Law. THIS NOTE WILL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
ANY CONFLICTS OF LAWS PROVISIONS THEREOF THAT WOULD OTHERWISE REQUIRE THE
APPLICATION OF THE LAW OF ANY OTHER JURISDICTION.

                           (ii) Jurisdiction. The Company irrevocably submits to
the exclusive jurisdiction of any State or Federal Court sitting in the State of
New York, County of New York, over any suit, action, or proceeding arising out
of or relating to this Note. The Company irrevocably waives, to the fullest
extent permitted by law, any objection which it may now or hereafter have to the
laying of the venue of any such suit, action, or proceeding brought in such a
court and any claim that suit, action, or proceeding has been brought in an
inconvenient forum.

                                The Company agrees that the service of process
upon it mailed by certified or registered mail (and service so made shall be
deemed complete three days after the

                                       16
<PAGE>

same has been posted as aforesaid) or by personal service shall be deemed in
every respect effective service of process upon it in any such suit or
proceeding. Nothing herein shall affect Holder's right to serve process in any
other manner permitted by law. The Company agrees that a final non-appealable
judgement in any such suit or proceeding shall be conclusive and may be enforced
in other jurisdictions by suit on such judgment or in any other lawful manner.

                           (iii) No Jury Trial. THE COMPANY HERETO KNOWINGLY AND
VOLUNTARILY WAIVES ANY AND ALL RIGHTS IT MAY HAVE TO A TRIAL BY JURY WITH
RESPECT TO ANY LITIGATION BASED ON, OR ARISING OUT OF, UNDER, OR IN CONNECTION
WITH, THIS NOTE.

                  (g) Replacement Notes. This Note may be exchanged by Holder at
any time and from time to time for a Note or Notes with different denominations
representing an equal aggregate outstanding Principal Amount, as reasonably
requested by Holder, upon surrendering the same. No service charge will be made
for such registration or exchange. In the event that Holder notifies the Company
that this Note has been lost, stolen or destroyed, a replacement Note identical
in all respects to the original Note (except for registration number and
Principal Amount, if different than that shown on the original Note), shall be
issued to the Holder, provided that the Holder executes and delivers to the
Company an agreement reasonably satisfactory to the Company to indemnify the
Company from any loss incurred by it in connection with this Note.
