         FOR VALUE RECEIVED, Indus International, Inc., a Delaware corporation
(the "Company"), hereby promises to pay to the order of [_____] (the "Holder")
at the address of the Holder indicated on the signature page(s) hereto, or at
such other place as the Holder may designate in writing to the undersigned, in
lawful money of the United States of America, and in immediately available
funds, the principal amount of [_____] Dollars ($[_____]) (the "Principal
Amount"), together with interest on the principal balance hereof as hereinafter
set forth. This Note is one of the "Notes" issued pursuant to the Purchase
Agreement, dated as of the date hereof (as amended, modified or supplemented,
the "Purchase Agreement"). Capitalized terms used and not otherwise defined
herein shall have the respective meanings ascribed thereto in the Purchase
Agreement.

         1.       Payment Terms. Until paid in full, interest on the principal
balance of this Convertible Note (this "Note") from time to time outstanding
shall accrue from the date hereof at a rate per annum of eight percent (8.0%).
Interest shall be payable quarterly in arrears on each three month anniversary
of the date hereof, beginning three months from the date hereof. Interest shall
be computed on the basis of a three hundred and sixty-five day year and shall
be paid for the actual number of days on which principal is outstanding. In any
event, the entire outstanding principal balance of this Note, together with any
accrued interest and other charges as may be due hereunder, shall be paid on
December 5, 2003 (the "Maturity Date").

         In no event shall the amount of interest due or payable under this
Note exceed the maximum rate of interest allowed by applicable law and, in the
event any such payment is inadvertently paid by the undersigned or
inadvertently received by the Holder, then such excess sum shall be credited as
a payment of principal, unless the undersigned shall notify the Holder in
writing that the undersigned elects to have such excess sum returned to it
forthwith. It is the express intent of the parties hereto that the undersigned
not pay and the Holder not receive, directly or indirectly, in any manner
whatsoever, interest in excess of that which may be lawfully paid by the
undersigned under the applicable law.

         2.       Solicitation of Stockholder Approval; Conversion. The Company
will use its commercially reasonable efforts to file as promptly as
practicable, but in no event later than thirty (30) days from the date hereof,

approval of the Company's stockholders (the "Stockholder Approval") to the
issuance of the shares of the Company's common stock, which are issuable upon
conversion of this Note (the "Conversion


                                       1
<PAGE>
Shares"). Upon receipt of the Stockholder Approval (such date, the "Conversion
Date"), this Note will automatically and immediately convert into whole
Conversion Shares at a price equal to $1.50 per share, subject to adjustment
pursuant to Section 6 hereof (as it may be so adjusted, the "Conversion
Price"). Any and all accrued interest on the Note will also be paid to the
Holder in whole Conversion Shares. The amount of accrued interest to be paid in
Conversion Shares will be based upon the Principal Amount of this Note.

         At the Conversion Date, or as promptly as practicable thereafter, the
Company shall issue and deliver to the Holder (or such other person as directed
by the Holder) a certificate or certificates for the full number of shares of
Conversion Shares to which the Holder is entitled. The Company will not issue
any fractional interests in Conversion Shares, and the Company will pay to the
Holder is cash the amount of the unconverted principal balance of this Note
that would otherwise be converted into such fractional interests. Such
conversion shall be deemed to have been made immediately prior to the close of
business on the Conversion Date, and the person or persons entitled to receive
Conversion Shares issuable upon such conversion shall be treated for all
purposes as the record holder or holders of such Conversion Shares as of such
date. At the Conversion Date, this Note shall evidence the Holder's right to
receive the Conversion Shares to which the Holder is entitled.

         3.       Prepayment. This Note shall not be subject to prepayment
unless the Stockholder Approval is not obtained by the Company by the
Expiration Date, whereafter the outstanding principal balance of this Note, and
accrued interest thereon, may be prepaid in whole or in part at any time
without premium or penalty and without the prepayment of unearned interest.

         4.       Costs; Waivers. The Company agrees to pay all costs
(including reasonable attorney's fees, expenses and disbursements) of Holder in
connection with the collection and/or enforcement of this Note. The Company
hereby forever waives demand, presentment for payment, protest, notice of
protest, notice of dishonor of this Note and all other demands and notices in
connection with the delivery, acceptance, performance and enforcement of this
Note. No delay or omission on the part of Holder in exercising any rights
hereunder shall operate as a waiver of such rights or any other rights of
Holder, nor shall any delay, omission or waiver on one occasion be deemed a bar
to or waiver of the same or any other right on future occasions.

         5.       Change of Control. If at any time after the date of issuance
of this Note and prior to the Maturity Date, the Company shall undergo a Change
of Control (as defined below), then the holder hereof shall have the option to
accelerate the Maturity Date to the date of the consummation of such Change of
Control and demand payment of all outstanding principal and unpaid accrued
interest on this Note in full in lawful money of the United States of America
payable at the principal office of the Company, or at such other place as the
holder hereof may from time to time designate in writing to the Company. A

assuming for purposes hereof that all of the Shares are issued and outstanding
as of such date, no longer retain stock or other equity interests representing
a majority of the voting power of the Company.

presentment, demand, protest or notice of any kind. Upon the occurrence and
