                       CONVERTIBLE SECURED PROMISSORY NOTE

                  For value received VIADOR INC., a Delaware corporation (the
"Company"), promises to pay               or his assigns ("Lender") the
 -------                    -------------                  ------
principal sum of                  (           ) together with interest, payable
                 -----------------  -----------
in arrears, at a rate per annum equal to the "prime rate" plus (i) one percent
                                              ----------
(1%) on the outstanding principal amount from the date hereof until the earlier
of the Maturity Date (as defined below) or conversion (as applicable) and (ii)
three percent (3%) on the outstanding principal amount from the Maturity Date,
compounded quarterly, until all outstanding principal and accrued interest are
paid in full if not converted. For the purpose of calculating interest, the
"prime rate" for any calendar month shall be the prime rate as quoted in the
 ----------
Western Edition of the Wall Street Journal (or any successor publication) on the
first business day of such month (or if on such date no Wall Street Journal is
published the date next preceding on which a Wall Street Journal quoting a prime
rate was published). All computations of interest shall be made on the basis of
a year of 365 or 366


                                       1

days, as the case may be, for the actual number of days (including the first day
but excluding the last day) occurring in the period for which such interest is
payable.

                  This Convertible Promissory Note (this "Note") is one in a
                                                          ----
series of promissory notes issued pursuant to that certain Convertible
Promissory Note and Warrant Purchase Agreement between the Company and the
Lender, dated as of July __, 2001 (as the same may from time to time be amended,
modified or supplemented, the "Purchase Agreement"). Lender is subject to
                               ------------------
certain restrictions set forth in the Purchase Agreement and shall be entitled
to certain rights and privileges set forth in the Purchase Agreement. This Note
is one of the Notes referred to as the "Notes" in the Purchase Agreement.
Capitalized terms not otherwise defined herein shall have the meaning ascribed
to them in the Purchase Agreement.

1. The outstanding principal amount of this Note and unpaid accrued interest
thereon shall be due and payable on September __, 2001 (the "Maturity Date");
provided, however, that the principal amount of this Note and accrued interest
thereon may be prepaid in whole or in part at any time, and from time to time,
without penalty or premium. Any prepayment will be applied first to the payment
of accrued unpaid interest and second to the payment of principal. Lender may,
subject to paragraphs 4 and 5 hereof, convert such outstanding principal of this
Note and unpaid accrued interest thereon (the "Lender's Conversion Option") into
                                               --------------------------
shares of the Company's Common Stock ("Common Stock") or other equity
                                       ------------
securities, in accordance with terms and conditions of paragraph 3 hereof.

2. All payments of interest and principal shall be in lawful money of the United
States of America not later than 5:00 p.m. Pacific Standard Time on the date for
payment, at the principal office of the Company, or at such other place as the
Lender may from time to time designate in writing to the Company in accordance
with the terms hereof. All payments shall be applied first to unpaid accrued
interest and thereafter to principal. Whenever any payment hereunder shall be
stated to be due, or whenever any interest payment date or any other date
specified hereunder would otherwise occur, on a day other than a Business Day
(as defined below), then such payment shall be made, and such interest payment
date or other date shall occur, on the next succeeding Business Day, and such
extension of time shall in such case be included in the computation of payment
of interest hereunder. As used herein, "Business Day" means a day (i) other than
                                        ------------
Saturday or Sunday, and (ii) on which commercial banks are open for business in
San Francisco, California

3.

(A) Lender shall have the option to convert any or all of the principal amount
and unpaid accrued interest on this Note into (i) shares of Common Stock at a
conversion price equal to the lower of (a) the average closing bid price of the
Common Stock as quoted on the Nasdaq National Market ("NASDAQ") or other
                                                       ------
over-the-counter exchange during the twenty (20) trading days prior to the date
of this Note, or (b) the average closing bid price of the Common Stock as quoted
on NASDAQ or other over-the-counter exchange during the twenty (20) days prior
to the date of conversion, or (ii) equity securities issued by the Company to a
third party or third parties in one or more bona fide, arms-length transactions
for the purpose of raising capital during the term of this Note, at a conversion
price equal to the price per share or unit at which such equity securities are
sold to such third party or third parties, provided that, the Company informs


                                      2

<PAGE>

Lender of its desire to have Lender convert such Note into the equity securities
and Lender agrees to such conversion. Notwithstanding the foregoing, if Lender
does not agree to convert the Note as provided in (ii) above, Lender may require
Company to pay in full the outstanding principal and accrued interest on the
Note up to the date the equity securities are issued.

(B) The Lender's Conversion Option is exercisable by Lender only by written
notification to the Company within fifteen (15) days of the date that the Lender
intends to exercise the Lender's Conversion Option. The Lender's Conversion
Option lapses on the later of (1) the Maturity Date or (2) the date all
principal and accrued interest is paid under the Note. The notice of election to
convert from the Lender shall specify the name or names (if other than the name
of the Lender) in which the certificate or certificates for conversion shares
are to be issued. The Lender shall surrender this Note at the principal offices
of the Company. The Company shall as soon as practicable following surrender of
this Note, issue and deliver to the Lender, or to the nominee or nominees of the
Lender, a certificate or certificates for the number of conversion shares into
which this Note shall have been converted.

(C) Notwithstanding the foregoing, in no event shall Lender be entitled to
convert this Note into a total number of shares of voting stock of Company that
exceeds that number of shares which is equal to 19.9% of the Company's total
issued and outstanding shares of voting stock as of the date of such conversion,
less such number of shares of common stock (if any) that are then held by Lender
or any other holder of a Note or Warrant (a "Holder") and that were (a)
                                             ------
purchased by Lender or a Holder from any officers, directors or substantial
shareholders (as defined by the National Association of Securities Dealers) of
Company, or (b) acquired by Lender or a Holder upon exercise of any Note or
Warrant, including any shares with respect to which Lender or any Holder has
exercised any Warrant or converted any Note, but which have not yet been
delivered to Lender or such Holder, or (c) otherwise acquired (or other
securities convertible into voting stock of the Company otherwise acquired) by
the Lender or a Holder from the Company, or any officers, directors or
substantial shareholders (as defined by the National Association of Securities
Dealers) of Company, in connection with the transactions represented by the
Notes, Warrants or Purchase Agreement.

4. If the principal amount and interest accrued on this Note is converted into
Common Stock as provided in paragraph 3 hereof, the provisions of this Note
relating to the obligation of the Company to repay principal and any interest
accrued but unpaid to Lender, set forth above, shall be null and void and no
repayment of principal or payment of interest or other amounts shall be owed or
paid by the Company.

5. No fractional shares shall be issued upon the conversion of this Note. In
lieu of such fractional entitlement the Company may round up the number of
conversion shares issued on such conversion to the next highest whole share or
may pay in lawful money of the United States by check a sum equivalent to such
fractional entitlement based on the market value of a conversion share.

6. The Company shall not, by amendment of the Company's Certificate of
Incorporation or through any reorganization, recapitalization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to



                                      3

<PAGE>


avoid  the  observance  or  performance  of any of the terms to be  observed  or
performed hereunder by the Company,  but shall at all times in good faith assist
in the carrying out of all the provisions of Section 3.

7. The Company shall at all times reserve and keep available out of its
authorized but unissued Common Stock solely for the purpose of effecting the
conversion of this Note, such number of its conversion shares as shall from time
to time be sufficient to effect the conversion of this Note; and if at any time
the number of authorized but unissued conversion shares shall not be sufficient
to effect the conversion of this Note, the Company will take such corporate
action as may be necessary to increase its authorized but unissued conversion
shares to such number of shares as shall be sufficient for such purposes,
including, without limitation, engaging in best efforts to obtain the requisite
stockholder approval for any necessary amendment to its Certificate of
Incorporation.

8.       This Note shall not entitle Lender to any voting rights or other rights
as a stockholder of the Company.

9. The Company hereby grants to the Lender a security interest in all of the
Company's right, title and interest in and to, whether now existing or hereafter
acquired or arising and wherever located, all of the following (as defined in
the California Uniform Commercial Code): all accounts, chattel paper, deposit
accounts, documents, equipment, instruments, inventory, investment property,
letters of credit rights, money, and all books and records of the Company with
respect to the foregoing (collectively, the "Collateral"), to secure the payment
                                             ----------
and performance of the obligations of the Company under this Note. The
Collateral shall not include any of the Company's Intellectual Property (as
defined below). The Company shall establish a lockbox and will indicate to their
customers on each invoice to pay their accounts receivable payments into an such
established lockbox. The Company shall execute and deliver to the Lender, from
time to time, all financing statements and all other documents and instruments
and take all other action, as the Lender may reasonably request, to perfect and
continue perfected, maintain the priority of or provide notice of the Lender's
security interest in the Collateral. This Note shall create a continuing
security interest in the Collateral which shall remain in effect until the
payment in full of this Note. As used herein, "Intellectual Property" means all
                                               ---------------------
of the Company's right, title and interest in and to all computer software,
source code, inventions, improvements, works of authorship, derivative works,
data, utility models, algorithms, trade dress, schematics, flow charts, trade
secrets, designs, proprietary rights, technologies, proprietary knowledge,
know-how, trade names, including without limitation, copyrights, copyright
registrations and copyright applications, patents and patent applications, and
all rights and licenses to the foregoing, used in or useful to the conduct of
the Company's business.

10. Subject to the terms of the Purchase Agreement, any amendment hereto or
waiver of any provision hereof may be made only with the written consent of the
Company and Lender. Subject to the terms of the Purchase Agreement, this Note
shall inure to the benefit of and bind the successors, permitted assigns, heirs,

(C) any sale, lease, assignment, transfer, or other conveyance of all or
substantially all of the assets of the Company, or any consolidation or merger
involving the Company or any reclassification or other change of any stock, or
any recapitalization of the Company, or any transaction or series of related
transactions in which, in any such case, stockholders of the Company prior to
such consolidation, merger, reclassification, reorganization or similar
transaction cease to hold, directly or indirectly, at least fifty percent (50%)
of the voting power of the corporation; or

(D) the filing of a petition by or against the Company under any provision of
applicable bankruptcy or similar law relating to insolvency; or appointment of a
receiver, trustee, custodian or liquidator of or for all or any substantial part

for the benefit of creditors by the Company.

                  Upon the occurrence, and during the continuation, of any Event
of Default, Lender, at its option, may (i) by notice to the Company, declare the
unpaid principal amount of this Note and all other amounts payable hereunder to
be immediately due and payable, whereupon the unpaid principal amount of this
Note and all such other amounts shall become immediately due and payable,
without presentment, demand protest or further notice of any kind, provided,
                                                                   --------
however, that if an event described in paragraph (D) above shall occur, the

such notice; and (ii) whether or not the actions referred to in clause (i) have

herewith,  would exceed the amount of such interest computed on the basis of the
Highest  Lawful Rate,  the Company shall not be obligated to pay, and the Lender
shall not be entitled to charge, collect,  receive, reserve or take, interest in

payable  hereunder shall be computed on the basis of the Highest Lawful Rate. As
used herein,  "Highest Lawful Rate" means the maximum  non-usurious rate
               -------------------
of interest,  as in effect from time to time, which may be charged,
