                       ENLIGHTEN SOFTWARE SOLUTIONS, INC.

                             CONVERTIBLE DEMAND NOTE

$1,118,250                                                         March 6, 2001

               Enlighten Software Solutions, Inc. (the "Company"), a California
corporation, promises to pay to Maden Tech Consulting, Inc. or its assigns (the
"Lender"), at the time described below, the unpaid principal amount at any time
outstanding, which shall not exceed One Million One Hundred Eighteen Thousand
Two Hundred Fifty Dollars ($1,118,250) (the "Loan"), on demand of the Lender
made on or after July 15, 2001 (the "Maturity Date") or otherwise at the time
and in the manner set forth in the Loan Agreement dated as of February 14, 2001
by and between the Company and the Lender (as it may be amended, supplemented or
otherwise modified from time to time, the "Loan Agreement"). This Note is
referred to in, and is entitled to the benefits of, the Loan Agreement. The Loan
Agreement, among other things, (i) provides for the making of the Loan by the
Lender to the Company in the U.S. dollar amount first mentioned above, (ii)
contains provisions for acceleration of the maturity hereof upon the happening
of certain stated events upon the terms and conditions therein specified, and
(iii) contains provisions defining an Event of Default and the rights and
remedies of the Lender in such Event of Default. This Note, and any notes which
may be issued as a result of transfers, partial payments or partial conversions,
are referred to as "Notes." Capitalized terms used but not defined herein shall
have the meanings given to such terms in the Loan Agreement.

               1.     Interest and Payments.

               (a) The Company promises to pay interest on the outstanding
principal balance of the Loan from the date of any Advance under the Loan until
such principal amount is paid in full. Interest on outstanding Advances shall be
paid quarterly, in arrears, on the first day of January, April, July and October
of each year (each an "Interest Payment Date"), with the first interest payment
to be made on April 1, 2001 (or such later day as is the first Interest Payment
Date after the date of this Note). Interest shall be computed monthly at a rate
for each month equal to the applicable Federal short-term rate announced by the
Internal Revenue Service pursuant to Section 1274(d) of the Internal Revenue
Code of 1986, as amended, through a Revenue Ruling published in the Internal
Revenue Bulletin during the preceding month based on the actual number of days
elapsed in such month in a year of 365 or 366 days. If any Interest Payment Date
is not a Business Day, the Interest Payment Date will be deferred until the next
Business Day, and interest will be payable through that next Business Day.

               (b) Each Advance made by the Lender to the Company, and all
payments made on account of principal thereof, shall be recorded by the Lender
and, prior to any permitted transfer hereof, endorsed on Schedule A attached
hereto which is part of this Note; provided, however, that the failure to make
any such recordation or endorsement shall not affect the obligation of the
Company under this Note.

               (c) Each payment of principal or interest will be made to the
Lender by certified or bank cashier's check or wire transfer of immediately
available funds, at such address

<PAGE>   3

or to such account as the Lender specifies to the Company in writing at least
three business days before the payment is to be made, except that the Company
may, with the written consent of the Lender, make any interest payment due with
Common Stock with a value, based on the Current Market Price (as defined in
Section 3(c) hereof) of the Common Stock on the applicable Interest Payment Date
equal to the amount of the interest payment due. Any fractional interest in
respect of a share of Common Stock arising upon an interest payment made in
Common Stock will be paid in cash (computed to the nearest cent) based on the
Current Market Price of the Common Stock.

               (d) If the Obligations exceed the Facility Cap, and such excess
continues for a period of more than five (5) Business Days during any month
following notice to the Company, then that portion of the Obligations that
exceeds such limitation shall bear interest at the rate as calculated above plus
an additional 2% per annum until paid.

               (e) If any interest payment or other payment due hereunder is not
received by Lender within five (5) Business Days of the day such payment is due
and payable, then the Company shall pay to the Lender a late charge equal to 15%
of the amount of such interest or other payment not timely made.

               (f) Upon the occurrence of an Event of Default and during the
continuation thereof, and after notice to the Company by the Lender, the rate of
interest in effect at such time with respect to the Obligations shall be
increased to the Default Rate.

               (g) The Obligations under this Note may not be repaid in whole or
from time to time in part without the written consent of the Lender.

               (h) This Note is hereby expressly limited so that in no
contingency or event whatsoever, whether by reason of acceleration or otherwise,
shall the amount paid or agreed to be paid to the Lender for the use,
forbearance or detention of money hereunder exceed the maximum amount
permissible under applicable law. If, due to any circumstance whatsoever,
fulfillment of any provision hereof, at the time performance of such provision
shall be due, shall exceed any limits prescribed by law, then, ipso facto, the
obligation to be fulfilled shall be reduced to such lawful limit, and if the
Lender shall have received interest, or any other payment of any kind which
might be deemed to be interest under applicable law in excess of the highest
lawful rate, then such excess amount shall be applied to the reduction of the
outstanding principal balance owing under this Note and not to the payment of
interest, or if such excess interest exceeds the unpaid balance of principal of
this Note and any other Obligations (other than any Obligations in respect of
indemnification and expense reimbursement hereunder and under any other Loan
Document to the extent such Obligations are not then due and payable) hereunder
or under the Loan Agreement that lawfully may be satisfied with such excess
interest, such excess interest shall be refunded to the Company. The terms and
provisions of this Section shall control to the extent inconsistent with other
provisions of this Note.

               2.     Lender's Rights upon Certain Events.

               (a) The Company may not sell all or substantially all its assets
or consent to or participate in a transaction which involves a sale of a
majority of its outstanding stock, unless (a) at least forty days before the
record date for the transaction (or if there is no record date, at least 40 days
before the expected date of the transaction) the Company has notified the Lender
that (i) the transaction will take place (describing the transaction in
reasonable detail), (ii) this Note will be repaid on the date the transaction
takes place (specifying the expected date), and (iii) the Lender will have the
right to convert this Note into Common Stock at any time before 5:00 p.m. on the
day before the record date for determining the shareholders of the Company
entitled to participate in the transaction (or if there is no record date, the
tenth day before the expected date of the transaction), (b) if not later than
ten days after the Company gives the notice to the Lender, either the Lender or
the Company notifies the other of them that, in its opinion (based upon advice
of counsel), the shares the Company is required to issue upon conversion of this
Note may not be issued until filings have been made under the HSR Act and the
waiting periods required by the HSR Act have either expired or terminated, the
record date for the transaction (or if there is no record date, the date of the
transaction) will be not earlier than the day specified in clause (z) of Section
4(a), and (c) the Lender consents to the proposed transaction in writing. If the
Lender presents this Note for conversion within 30 days after the Company gives
a notice of the type described in the preceding sentence, the Lender may specify
that the conversion will be subject to, and will be effective immediately
before, completion of the transaction described in the notice.

               (b) If at any time there is to be a Change of Control, in
addition to its right to demand payment hereunder (whether in cash or by
conversion pursuant to Section 3 below), the Lender will have the option, which
the Lender may exercise upon notice to the Company given not later than ten
Business Days after the Company notifies the Lender of the Change of Control, to
require the Company to repurchase this Note for an amount equal to 100% of the
principal amount then outstanding plus accrued but unpaid interest to the date
of repurchase. If the Lender presents this Note for conversion after the Company
gives notice that a Change of Control is to occur, the Lender may specify that
the conversion is subject to the Change of Control's occurring, and will be
effective immediately before the Change of Control occurs.

               3. Conversion. The Lender will have the right at any time
(subject to the provisions of Section 2 hereof), at the Lender's option, to
convert all or any of the outstanding principal amount of all Advances
outstanding under this Note, together with any accrued but unpaid interest on
such principal amount to be converted (the "Conversion Amount"), into the number
of fully paid and non-assessable shares of Common Stock of the Company
(calculated as to each conversion to the nearest 1/100th of a share) equal to
(x) the Conversion Amount divided by (y) the Conversion Price (as defined in
Section 3(c)), or such other securities or assets as the Lender is entitled to
receive in accordance with Section 3(c); provided, however, that the maximum
number of shares of Common Stock issuable by the Company upon any such
conversion or series of conversions shall not exceed 49.99% of the aggregate
number of shares of Common Stock outstanding immediately after (and giving
effect to) such conversion.

                      (a) (i) In order to exercise the conversion privilege, the
Lender must surrender this Note, with the Notice of Election to Convert duly
completed and signed, to

<PAGE>   5

the Company at its principal office (or, if the Company has appointed a
conversion agent other than itself, to the conversion agent at the office
specified by the Company in a notice to the Lender). If the Conversion Amount is
less than the aggregate principal amount of all Advances outstanding under this
Note, the Company will issue to the Lender a new Note, with the same terms as
this Note, in a principal amount equal to the face amount of this Note less all
Advances of principal being converted.

                             (ii) Each conversion will be at the Conversion
Price in effect at the close of business on the day when all the conditions in
Section 3(a)(i) and Section 4(a) have been satisfied.

                             (iii) The Company will not make any payment or
adjustment for accrued interest (including overdue interest) with regard to any
Advances of principal under this Note which are converted, or for dividends on
the shares of Common Stock issued upon the conversion.

                             (iv) As promptly as practicable after this Note is
surrendered and all the other conditions in Section 3(a)(i) and Section 4(a)
have been satisfied, the Company will issue and will deliver to the Lender at
the office of the Company, or on the Lender's written order, a certificate or
certificates for the number of full shares of Common Stock issuable upon the
conversion. Any fractional interest in respect of a share of Common Stock
arising upon a conversion will be settled as provided in Section 3(b).

                             (v) A conversion under this Note will be deemed to
be effected immediately prior to the close of business on the day on which all
the conditions specified in Section 3(a)(i) and Section 4(a) have been
satisfied, and the Lender will be deemed to have become the holder of record at
that time of the shares of Common Stock into which the Conversion Amount is
converted, regardless of when certificates representing those shares are issued.
All shares of Common Stock delivered upon conversion of the Conversion Amount
will upon delivery be duly and validly issued and fully paid and nonassessable,
free of all liens and charges and not subject to any preemptive rights.

                      (b) No fractional shares of Common Stock will be issued
upon any conversion of this Note. Any fractional interest in a share of Common
Stock resulting from any conversion of this Note will be paid in cash (computed
to the nearest cent) based on the Current Market Price of the Common Stock on
the Trading Day (as defined in Section 3(d)(vii)) next preceding the day of
conversion.

                      (c) The "Conversion Price" initially will be $0.225, and
will be adjusted as follows from time to time if any of the events described
below occurs after February 14, 2001.

                             (i) If the Company (A) pays a stock dividend or
makes a distribution on its Common Stock in shares of its Common Stock, (B)
subdivides its outstanding Common Stock into a greater number of shares, or (C)
combines its outstanding Common Stock into a smaller number of shares, the
Conversion Price in effect immediately prior to that event will be adjusted so
that upon conversion of any Conversion Amount under this Note after that

<PAGE>   6

event, the Lender will receive the number of shares of Common Stock which the
Lender would have received if the Conversion Amount had been converted
immediately before the happening of the event (or, if there is more than one
such event, if the Conversion Amount had been converted immediately before the
first of those events and the Lender had retained all the Common Stock or other
securities or assets received after the conversion). An adjustment made pursuant
to this Section 3(c) will become effective immediately after the record date in
the case of a dividend or distribution, except as provided in Section
3(c)(viii), and will become effective immediately after the effective date in
the case of a subdivision or combination. If a dividend or distribution is
declared but is not paid or made, the Conversion Price then in effect will be
appropriately readjusted. However, a readjustment of the Conversion Price will
not affect any conversion which takes place before the readjustment.

                             (ii) If the Company issues rights or warrants to
the holders of its Common Stock as a class entitling them (for a period expiring
within 45 days after the record date for issuance of the rights or warrants) to
subscribe for or purchase Common Stock at a price per share less than the
Conversion Price at the record date for the determination of shareholders
entitled to receive the rights or warrants, the Conversion Price in effect
immediately before the issuance of the rights or warrants will be reduced so
that it will be the amount determined by multiplying the Conversion Price in
effect immediately before the record date for the issuance of the rights or
warrants by a fraction of which the numerator is the number of shares of Common
Stock outstanding on the record date for the issuance of the rights or warrants
plus the number of shares of Common Stock which the aggregate exercise price of
all the rights or warrants would purchase at the Conversion Price at that record
date, and of which the denominator is the number of shares of Common Stock
outstanding on the record date for the issuance of the rights or warrants plus
the number of additional shares of Common Stock issuable on exercise of all the
rights or warrants. The adjustment provided for in this Section 3(c)(ii) will be
made successively whenever any rights or warrants are issued, and will become
effective immediately, except as provided in Section 3(c)(viii), after each
record date. In determining whether any rights or warrants entitle the holders
of the Common Stock to subscribe for or purchase shares of Common Stock at less
than the Conversion Price, and in determining the aggregate sale price of the
shares of Common Stock issuable on the exercise of rights or warrants, there
will be taken into account any consideration received by the Company for the
rights or warrants, with the value of that consideration, if other than cash, to
be determined by the Board of Directors of the Company (whose determination, if
made in good faith, will be conclusive). If any rights or warrants which lead to
an adjustment of the Conversion Price expire or terminate without having been
exercised, the Conversion Price then in effect will be appropriately readjusted.
However, a readjustment of the Conversion Price will not affect any conversions
which take place before the readjustment.

                             (iii) If the Company distributes to the holders of
its Common Stock as a class any shares of capital stock of the Company (other
than Common Stock) or evidences of indebtedness or assets (other than cash
dividends or distributions of cash paid from retained earnings of the Company)
or rights or warrants (other than those referred to in Section 3(c)(ii)) to
subscribe for or purchase any of its securities, then, in each such case, the
Conversion Price will be reduced so that it will equal the price determined by
multiplying the Conversion Price in effect immediately prior to the record date
for the distribution by a fraction of which the numerator is the Current Market
Price of the Common Stock on the record date for the

<PAGE>   7

distribution less the then fair market value (as determined by the Board of
Directors, whose determination, if made in good faith, will be conclusive) of
the capital stock, evidences of indebtedness, assets, rights or warrants which
are distributed with respect to one share of Common Stock, and of which the
denominator is the Current Market Price of the Common Stock on that record date.
Each adjustment will, except as provided in Section 3(c)(viii), become effective
immediately after the record date for the determination of the shareholders
entitled to receive the distribution. If any distribution is declared but not
made, or if any rights or warrants expire or terminate without having been
exercised, effective immediately after the decision is made not to make the
distribution or the rights or warrants expire or terminate, the Conversion Price
then in effect will be appropriately readjusted. However, a readjustment will
not affect any conversions which take place before the readjustment.

                             (iv) If there is a reclassification or change of
outstanding shares of Common Stock (other than a change in par value, or as a
result of a subdivision or combination), or a merger or consolidation of the
Company with any other entity that results in a reclassification, change,
conversion, exchange or cancellation of outstanding shares of Common Stock, or a
sale or transfer of all or substantially all of the assets of the Company, upon
any subsequent conversion of any Conversion Amount under this Note, the Lender
will be entitled to receive the kind and amount of securities, cash and other
property which the Lender would have received if the Lender had converted such
Conversion Amount into Common Stock immediately before the first of those events
and had retained all the securities, cash and other assets received as a result
of all those events.

                             (v) For the purpose of any computation under this
Note, the "Current Market Price" of the Common Stock on a day will be the
average of the last reported sale price per share of the Common Stock on each of
the five consecutive Trading Days (as defined below) preceding the date of the
computation. The last reported sale price of the Common Stock on a day will be
(A) the last sale price of the Common Stock before 4:00 p.m. reported on the
principal stock exchange on which the Common Stock is listed, or (B) if the
Common Stock is not listed on a stock exchange, the last sale price of the
Common Stock before 4:00 p.m. reported on the principal automated securities
price quotation system on which sale prices of the Common Stock are reported, or
(C) if the Common Stock is not listed on a stock exchange and sale prices of the
Common Stock are not reported on an automated quotation system, the mean of the
high bid and low asked price quotations for the Common Stock as reported by
National Quotation Bureau Incorporated if at least two securities dealers have
inserted both bid and asked quotations for the Common Stock on at least five of
the ten preceding Trading Days. If the Common Stock is not traded or quoted as
described in any of clause (A), (B) or (C), the Current Market Price of the
Common Stock on a day will be the fair market value of the Common Stock on that
day as determined in good faith by the Company's Board of Directors based upon
(and consistent with) written advice from a member firm of the New York Stock
Exchange, Inc. selected by the Board of Directors. As used in this Note, the
term "Trading Day" means (x) if the Common Stock is listed on at least one stock
exchange, a day on which there is trading on the principal stock exchange on
which the Common Stock is listed, (y) if the Common Stock is not listed on a
stock exchange, but sale prices of the Common Stock are reported on an automated
quotation system, a day on which trading is reported on the principal automated
quotation system on which sales of the Common Stock are reported, or (z) if the
Common Stock is not listed on a stock exchange and sale prices of the Common
Stock are

<PAGE>   8

not reported on an automated quotation system, a day on which quotations are
reported by National Quotation Bureau Incorporated.

                             (vi) No adjustment in the Conversion Price will be
required unless the adjustment would require a change of at least 1% in the
Conversion Price; provided, however, that any adjustments which are not made
because of this Section 3(c)(vi) will be carried forward and taken into account
in any subsequent adjustment. All calculations under this Section 3 will be made
to the nearest cent or to the nearest 1/100th of a share, as the case may be.

                             (vii) Whenever the Conversion Price is adjusted,
the Company will promptly send the holder of this Note a notice of the
adjustment of the Conversion Price setting forth the adjusted Conversion Price
and the date on which the adjustment becomes effective and containing a brief
description of the events which caused the adjustment.

                             (viii) In any case in which this Section 3 provides
that an adjustment will become effective immediately after a record date for an
event, the Company may defer until the occurrence of the event (A) issuing to
the holder of this Note, if the Conversion Amount is converted after the record
date and before the occurrence of the event, the additional shares of Common
Stock issuable upon the conversion by reason of the adjustment and (B) paying to
the Lender any cash in lieu of any fractional share as required by Section 3(b).

                      (d)    If:

                             (i) the Company declares a dividend (or any other
distribution) on the Common Stock (other than a dividend payable in cash out of
retained earnings); or

                             (ii) the Company authorizes the granting to the
holders of the Common Stock of rights or warrants to subscribe for or purchase
any shares of any class or any other rights or warrants; or

                             (iii) the Company issues, or changes the
conversion, exchange or exercise price of, any Convertible Securities (other
than the Notes), rights, options (other than stock options issued to employees
or directors of the Company or its subsidiaries under a plan approved by the
Company's shareholders) or warrants; or

                             (iv) the Company sells any Common Stock for less
than the Conversion Price on the date of the sale; or

                             (v) there is any reclassification of the Common
Stock (other than a subdivision or combination of the outstanding Common Stock
and other than a change in the par value, or from par value to no par value, or
from no par value to par value), or any consolidation, merger, or statutory
share exchange to which the Company is a party and for which approval of any
shareholders of the Company is required, or any sale or transfer of all or
substantially all the assets of the Company; or

                             (vi) there is a voluntary or an involuntary
dissolution, liquidation or winding up of the Company, then the Company will
mail to the Lender, at least 15 days before the applicable date specified below,
a notice stating the applicable one of (A) the

<PAGE>   9

date on which a record is to be taken for the purpose of the dividend,
distribution or grant of rights or warrants, or, if no record is to be taken,
the date as of which the holders of Common Stock of record who will be entitled
to the dividend, distribution or rights or warrants will be determined, (B) the
date on which it is expected the Convertible Securities will be issued or the
date on which the change in the conversion, exchange or exercise price of the
Convertible Securities, rights, options or warrants will be effective, or (C)
the date on which the reclassification, consolidation, merger, share exchange,
sale, transfer, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of record of
Common Stock will be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon the reclassification,
consolidation, merger, share exchange, sale, transfer, dissolution, liquidation
or winding up. Failure to give any such notice or any defect in the notice will
not affect the legality or validity of the reclassification, consolidation,
merger, share exchange, sale, transfer, dissolution, liquidation or winding up.

               4.     Covenants Relating to Conversion.

               (a) If (i) at or after the time when the Lender surrenders this
Note for conversion of any Conversion Amount into Common Stock and before the
Common Stock is issued, or (ii) under the circumstances described in Section 2
hereof, either the Lender or the Company notifies the other of them that, in its
opinion (based on advice of counsel), shares the Company is required to issue
upon conversion of such Conversion Amount may not be issued until filings have
been made under the HSR Act and the waiting periods required by the HSR Act have
either expired or been terminated, (w) the Lender and the Company will each make
as promptly as practicable the filing it is required to make under the HSR Act
with regard to the issuance of those shares upon conversion of this Note, (x)
each of them will provide information and cooperate in all other respects to
assist the other of them in making its filing under the HSR Act, (y) each of
them will take all reasonable steps within its control (including providing
information to the Federal Trade Commission or the Department of Justice) to
cause the waiting periods required by that Act to be terminated or to expire as
promptly as practicable, and (z) the time when the Company will issue the shares
of Common Stock which are the subject of the filing under the HSR Act will be
deferred until the day after the day on which the waiting periods under the HSR
Act expire or the Company is notified that the waiting periods under the HSR Act
have been terminated.

                      (b) If at the time when the Lender surrenders this Note
for conversion of any Conversion Amount into Common Stock (i) the Company's
shareholders have not approved the issuance upon such conversion of the shares
into which the Lender has elected to convert such Conversion Amount, and (ii)
the issuance of those shares on conversion of such Conversion Amount without
approval of the Company's shareholders would violate the rules of any stock
exchange or automated quotation system, the time when the Company will issue the
shares of Common Stock into which the Lender has elected to convert such
Conversion Amount will be deferred until the day after the day on which the
Company's shareholders approve the issuance of those shares.

                      (c) The Company will at all times reserve and keep
available, free from preemptive rights, out of the authorized but unissued
shares of Common Stock or the issued shares of Common Stock held in its
treasury, or both, for the purpose of effecting conversion of

<PAGE>   10

the Note, the maximum number of shares of Common Stock, if any, which the
Company would be required to deliver upon the conversion of the aggregate amount
of Advances under this Note then outstanding.

                      (d) Before taking any action which would cause an
adjustment reducing the Conversion Price below the then par value (if any) of
the shares of Common Stock deliverable upon conversion of this Note, the Company
will take all corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
non-assessable shares of Common Stock at the adjusted Conversion Price.

                      (e) The Company will endeavor to list the shares of Common
Stock it may be required to deliver upon conversion of this Note, as promptly as
practicable after the date of this Note, and in any event before they are
delivered, upon each national securities exchange or automated quotation system,
if any, upon which the Common Stock is listed at the time of delivery.

                      (f) Before the Company delivers any securities upon
conversion of this Note, the Company will endeavor, in good faith and as
expeditiously as possible, to comply with all federal and state laws and
regulations requiring the registration of those securities with, or any approval
of or consent to the delivery of those securities by, any governmental
authority. Inability of the Company to issue securities on conversion of this
Note within 90 days after it is presented for conversion, because of failure to
cause registration of those securities to become effective or to obtain any
approval of or consent to the delivery of those securities will constitute a
failure by the Company to fulfill its obligations under this Note, even if the
failure to cause a registration to become effective or to obtain an approval or
consent was due to factors beyond the Company's control, unless the registration
did not become effective or the approval or consent was not obtained because of
acts or failures to act by the Lender.

                      (g) The Company will pay any documentary stamp or similar
issue or transfer taxes payable in respect of the issue or delivery of shares of
Common Stock on conversion of this Note; except that the Company will not be
required to pay any foreign tax or any other tax which may be payable in respect
of any transfer involved in the issue or delivery of shares of Common Stock in a

unless and until the person requesting the issue or delivery has paid to the
Company the amount of any such tax or has established to the reasonable
satisfaction of the Company that the tax has been paid.

                                  EXHIBIT 10.3

<PAGE>   2

                       ENLIGHTEN SOFTWARE SOLUTIONS, INC.
                                WARRANT AGREEMENT

               THIS WARRANT AGREEMENT (this "Agreement") is made and entered
into as of March 6, 2001 between ENLIGHTEN SOFTWARE SOLUTIONS, INC., a
California corporation (the "Company"), and MADEN TECH CONSULTING, INC., a
Delaware corporation ("Maden Tech"). Certain capitalized terms used herein are
defined in Section 24 hereof.

               WHEREAS, the Company desires to obtain a credit facility from
Maden Tech upon the terms and subject to the conditions specified in the certain
Loan Agreement by and between the Company and Maden Tech dated as of February
14, 2001 (the "Loan Agreement"); and

               WHEREAS, as an inducement to Maden Tech to enter into the Loan
Agreement and provide the Credit Facility (as such term is defined in the Loan
Agreement), the Company has agreed to issue to Maden Tech Warrants, as
hereinafter described, to purchase shares of the Company's common stock, no par
value per share (the "Common Stock"), upon the terms and subject to the
conditions set forth herein; and

               WHEREAS, the Company wishes to set forth, among other things, the
provisions of such Warrants and the terms and conditions on which such Warrants
may be issued, exchanged, exercised and replaced.

               NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto agree as follows:

        1.     GRANT; FORM OF WARRANTS.

               The Company shall issue and deliver to Maden Tech on the date
hereof, a warrant (the "Warrant") to purchase 2,000,000 shares of Common Stock.
For all purposes of this Agreement, all shares of Common Stock which Maden Tech
may acquire upon exercise of a Warrant may be referred to as "Warrant Shares."
The number of Warrant Shares for which a Warrant shall be exercisable shall be
calculated in each case based on the criteria set forth herein. The Warrant, and
any additional Warrants which may be issued upon partial exercise, replacement
or transfer of such Warrant or Warrants, shall be evidenced by, and subject to
the terms of a Warrant Certificate (including the Forms of Election to Purchase
and Assignment attached thereto, a "Warrant Certificate") in the form of Exhibit
1 attached hereto, in each case executed on behalf of the Company by the manual
or facsimile signature of the President or Vice President of the Company, or in
facsimile, and attested by the Secretary or an Assistant Secretary of the
Company.

        2.     EXERCISE PRICE.

               Subject to the terms, conditions and adjustments herein set
forth, the Warrants shall be exercisable at a price per share equal to the
Current Market Price ("Exercise Price").

        3.     REGISTRATION.

               All Warrant Certificates shall be numbered and shall be
registered in a warrant register (the "Warrant Register") as they are issued.
Subject to its compliance with the foregoing, the Company shall be entitled to
treat the registered holder of any Warrant on the Warrant Register as the owner
in fact of such Warrant for all purposes and shall not be bound to recognize any
equitable or other claim to or interest in such Warrant on the part of any other
person or entity, and shall not be liable for any registration or transfer of
Warrants which are registered or to be registered in the name of a fiduciary or
the nominee of a fiduciary unless made with the actual knowledge that a
fiduciary or nominee is committing a breach of trust in requesting such
registration or transfer, or with the knowledge of such facts that its
participation therein amounts to bad faith.

<PAGE>   3

        4.     TRANSFER OF WARRANTS.

               (a) Neither any Warrant nor any Warrant Shares obtained upon
exercise of any Warrant may be offered, sold, transferred, pledged or otherwise
disposed of, in whole or in part, to any Person other than in accordance with
applicable federal and state securities laws.

               (b) Except as otherwise permitted by this Section 4, each Warrant
Certificate and each certificate evidencing any Warrant Shares issued upon
exercise of a Warrant shall be stamped or otherwise imprinted with a legend in
substantially the form as set forth on the form of Warrant Certificate attached
hereto as Exhibit 1. Notwithstanding the foregoing, a holder of a Warrant
Certificate or a certificate evidencing any Warrant Shares issued upon exercise
of a Warrant (a "Holder") may require the Company to issue a Warrant Certificate
or stock certificate, in each case without a legend, if and to the extent
permitted by, and in accordance with, applicable law.

               (c) Provided that a transfer is permitted under applicable law, a
Warrant may be transferred or endorsed to another party in whole or in part by
surrendering to the Company, or its duly authorized agent, for cancellation the
existing Warrant Certificate evidencing the Warrant to be transferred, endorsed
or accompanied by a written instrument of transfer, in form satisfactory to the
Company, duly executed by the holder thereof in person or by a duly authorized
representative, agent or attorney-in-fact appointed in writing. Upon receipt
thereof by the Company or such agent, the Company shall issue and deliver, or
cause such agent to issue and deliver, in the name of the transferee, a new
Warrant Certificate containing the same terms as the surrendered Warrant
Certificate. In the case of the transfer of fewer than all of the rights
evidenced by the surrendered Warrant Certificate, the Company shall issue a new
Warrant Certificate to the transferring Holder for the remaining number of
shares specified in the Warrant Certificate so surrendered.

        5.     EXERCISE OF WARRANTS.

               (a) Term of Exercise. Each Warrant Certificate shall entitle the
holder thereof to purchase up to such number of Warrant Shares as are specified
in the Warrant Certificate at the Exercise Price, in whole or in part, at any
time or from time to time, on any Business Day during the Exercise Period.

               (b) Mechanics of Exercise. To exercise a Warrant, the holder
thereof shall deliver to the Company, or its duly authorized agent, the Warrant
Certificate or Certificates evidencing such Warrant, with the Form of Election
to Purchase attached thereto duly completed and signed, together with payment to
the Company of the Exercise Price for the number of Warrant Shares in respect of
which the Warrant is then exercised. Upon such surrender of the Warrant
Certificate and payment of the Exercise Price as aforesaid, the Company shall
issue and cause to be delivered with all reasonable dispatch (and in any event
within five (5) Business Days of the surrender of such Warrant Certificate and
payment of the applicable Exercise Price) to or upon the written order of the
Holder of such Warrant, in such name or names as such Holder may designate on
the completed Election to Purchase, a certificate or certificates for the number
of Shares so purchased, together with cash, as provided in Section 13 of this
Agreement, in respect of any fraction of a Warrant Share otherwise issuable upon
such surrender. Such certificate or certificates shall be deemed to have been
issued and any person or entity so designated to be named therein shall be
deemed to have become a holder of record of such Warrant Shares as of the date
of the surrender of the Warrant Certificate and payment of the Exercise Price as
aforesaid. If any Warrant is exercised by its Holder in part, the Company shall
issue a new Warrant Certificate to the Holder exercisable for the remaining
number of Warrant Shares specified in the Warrant Certificate so surrendered
(which shall be in all other respects identical to the Warrant Certificate
surrendered).

               (c) Payment of Exercise Price. Payment of the Exercise Price may
be made in cash, by certified check or bank draft payable to the order of the
Company, by wire transfer of immediately available funds.

<PAGE>   4

               (d) Payment of Taxes. The Company shall pay all expenses, taxes
and other governmental charges with respect to the issue or delivery of the
Warrant Shares, unless such tax or charge is required by law to be imposed upon
the Holder. The Company shall not be required, however, to pay any transfer tax
or other similar charge imposed in connection with the issue of any certificate
for Warrant Shares in any name other than that of the Holder, and in such case
the Company shall not be required to issue or deliver any stock certificate
until such tax or other charge has been paid or it has been established to the
satisfaction of the Company that no such tax or other charge is due.

        6.     MUTILATED OR MISSING WARRANT CERTIFICATE.

               If a Warrant Certificate is mutilated, lost, stolen or destroyed,
the Company shall issue and deliver (a) in exchange and substitution for and
upon cancellation of any mutilated Warrant Certificate or (b) in lieu of and in
substitution for any Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor representing an equivalent right or interest;
but only upon receipt of evidence reasonably satisfactory to the Company of such
loss, theft or destruction of such Warrant Certificate including, without
limitation, an Affidavit of Loss executed by the Holder.

        7.     RESERVATION OF COMMON STOCK, ETC.

               The Company shall reserve, for so long as any Warrant remains
outstanding, a number of authorized and unissued Warrant Shares sufficient to
provide for the exercise in full of any and all such Warrants, and the transfer
agent for the Common Stock, which may be the Company (the "Transfer Agent"), is
hereby irrevocably authorized and directed at all times until all such Warrants
have been exercised in full or otherwise surrendered for cancellation to reserve
such number of authorized and unissued Warrant Shares as necessary for such
purpose. The Company shall keep copies of this Agreement on file with the
Transfer Agent and shall supply the Transfer Agent with duly executed stock
certificates for issue and delivery for such purpose and will itself provide or
otherwise make available any cash payable as provided in Section 13 of this
Agreement. All Warrant Certificates surrendered upon the exercise of a Warrant
shall be, and such Warrant Certificates shall constitute, sufficient evidence of
the number of Warrant Shares which have been issued upon the exercise of
Warrants. The Company covenants and agrees that upon exercise of the Warrants
and payment of the Exercise Price therefor, all Warrant Shares issuable upon
such exercise shall be duly and validly issued, fully paid and non-assessable,
not subject to the preemptive rights of any shareholder, and free from all
taxes, liens, security interests, charges, and other encumbrances with respect
to the issuance thereof, other than taxes in respect of any transfer occurring
contemporaneously with such issuance.

        8.     ADJUSTMENTS.

               The number of Warrant Shares and the Exercise Price of each
Warrant shall be subject to adjustment from time to time as set forth in this
Section 8. The Company shall give the Holder notice of any event described below
which requires an adjustment pursuant to this Section 8 in accordance with
Section 12.

               (a) Mechanical Adjustments. The number of Warrant Shares
purchasable upon the exercise of each Warrant and the Exercise Price shall be
subject to adjustment as follows:

                      (1) Adjustment for Change in Capital Stock. Subject to
paragraph 8(a)(6) below, in case the Company shall (i) pay a dividend on its
outstanding shares of Common Stock in shares of Common Stock or make a
distribution of shares of Common Stock on its outstanding shares of Common
Stock, (ii) make a distribution on its outstanding shares of Common Stock in
shares of its capital stock other than Common Stock, (iii) subdivide its
outstanding shares of Common Stock into a greater number of shares of Common
Stock, (iv) combine its outstanding shares of Common Stock into a smaller number
of shares of

<PAGE>   5

Common Stock, or (v) issue, by reclassification of its shares of Common Stock,
other securities of the Company (including any such reclassification in
connection with a consolidation or merger in which the Company is the surviving
entity), then the number of Warrant Shares purchasable upon exercise of a
Warrant immediately prior thereto shall be adjusted so that the Holder shall be
entitled to receive the kind and number of Warrant Shares or other securities of
the Company which such Holder would have owned or have been entitled to receive
upon the happening of any of the events described above had such Warrant been
exercised in full immediately prior to the happening of such event or any record
date with respect thereto. An adjustment made pursuant to this paragraph 8(a)(1)
shall become effective immediately after the record date for such event or, if
none, immediately after the effective date of such event. Such adjustment shall
be made successively whenever such an event occurs.

                      (2) Adjustment for Rights Issue. Subject to paragraph
8(a)(6) below, in case the Company shall issue rights, options or warrants
(collectively, "Rights") to all holders of its outstanding Common Stock
entitling them to subscribe for or purchase shares of Common Stock at a Price
Per Share (as defined in paragraph 8(a)(5) below) which is lower at the record
date mentioned below than the then Current Market Price per share of Common
Stock, the number of Warrant Shares thereafter purchasable upon the exercise of
a Warrant shall be determined by multiplying the number of Warrant Shares
theretofore purchasable upon exercise of such Warrant by a fraction, the
numerator of which shall be the sum of (a) the total number of shares of Common
Stock and shares of Common Stock issuable upon the exercise of Convertible
Securities (as defined in paragraph 8(a)(4) below), each as outstanding on the
date of issuance of such Rights plus (b) the additional Number of Shares (as
defined in paragraph 8(a)(5) below) of Common Stock offered for subscription or
purchase in connection with such Rights and the denominator of which shall be
the sum of (x) the total number of shares of Common Stock and shares of Common
Stock issuable upon the exercise of Convertible Securities, each as outstanding
on the date of issuance of such Rights plus (y) the number of shares which the
aggregate Proceeds (as defined in paragraph 8(a)(5) below) received or
receivable by the Company upon exercise of such Rights would purchase at the
Current Market Price per share of Common Stock at such record date. Such
adjustment shall be made whenever Rights are issued, and shall become effective
immediately after the record date for the determination of shareholders entitled
to receive Rights, provided, that except as provided in paragraph 8(a)(10)
below, no further adjustment of the number of Warrant Shares issuable upon
exercise of such Warrant shall be made upon the actual issue of Warrant Shares.

                      (3) Adjustment for Other Distributions. Subject to
paragraph 8(a)(6) below, in case the Company shall distribute to all holders of
its shares of Common Stock (x) evidences of indebtedness or assets (excluding
cash dividends or distributions payable out of the consolidated earnings or
surplus legally available for such dividends or distributions and dividends or
distributions referred to in paragraphs 8(a)(1) or (2) above) of the Company or
any corporation or other legal entity a majority of the voting equity or equity
interests of which are owned, directly or indirectly, by the Company (a
"Subsidiary"), or (y) shares of capital stock of a Subsidiary (such evidences of
indebtedness, assets and securities as set forth in clauses (x) and (y) above,
collectively, "Assets"), then in each case the number of Warrant Shares
thereafter purchasable upon the exercise of a Warrant shall be determined by
multiplying the number of Warrant Shares theretofore purchasable upon the
exercise of such Warrant by a fraction, the

<PAGE>   6

numerator of which shall be the Current Market Price per share of Common Stock
on the date of such distribution and the denominator of which shall be the
difference between (a) such Current Market Price per share of Common Stock and
(b) the fair value as of such record date as determined reasonably and in good
faith by the Board of Directors of the portion of the Assets applicable to one
share of Common Stock. Such adjustment shall be made whenever any such
distribution is made, and shall become effective on the date of distribution
retroactive to the record date for the determination of shareholders entitled to
receive such distribution.

               (4) Adjustment for Common Stock and Convertible Securities Issue.
Subject to paragraph 8(a)(6) below, in case the Company shall issue shares of
its Common Stock, or securities convertible into, or exchangeable or exercisable
for Common Stock or Rights to subscribe for or purchase such securities
(collectively, "Convertible Securities") (excluding the issuance of (i) Common
Stock or Convertible Securities issued in any of the transactions described in
paragraphs 8(a)(1), (2) or (3) above or Section 8(d) below, (ii) securities
issued pursuant to or in connection with any Permitted Issuance, or (iii) shares
of Common Stock issued upon the exercise of the Warrants) at a Price Per Share
of Common Stock, in the case of the issuance of Common Stock, or at a Price Per
Share of Common Stock initially deliverable upon conversion or exercise of
exchange of such Convertible Securities, in each case, together with any other
consideration received by the Company in connection with such issuance, below
the then Current Market Price per share of Common Stock on the date the Company
fixed the offering, conversion or exercise or exchange price of such additional
shares, then the number of Warrant Shares thereafter purchasable upon the
exercise of a Warrant shall be determined by multiplying the number of Warrant
Shares theretofore purchasable upon exercise of such Warrant by a fraction, the
numerator of which shall be the sum of (a) the total number of shares of Common
Stock and shares of Common Stock issuable upon the exercise of Convertible
Securities (in each case, excluding all shares being issued for which adjustment
is being made pursuant to this paragraph 8(a)(4)), each as outstanding on such
date plus (b) the additional Number of Shares of Common Stock offered for
subscription or purchase, and the denominator of which shall be the sum of (x)
the total number of shares of Common Stock and shares of Common Stock issuable
upon the exercise of Convertible Securities (in each case, excluding all shares
being issued for which adjustment is being made pursuant to this paragraph
8(a)(4)), each as outstanding on such date plus (y) the number of shares of
Common Stock which the aggregate Proceeds of the total amount of Convertible
Securities so offered would purchase at the Current Market Price Per Share of
Common Stock at such record date. In case the Company shall issue and sell
Convertible Securities for a consideration consisting, in whole or in part, of
property other than cash or its equivalent, then in determining the "Price Per
Share" of Common Stock and the "consideration received by the Company" for
purposes of the first sentence and the immediately preceding sentence of this
paragraph 8(a)(4), the Board of Directors shall reasonably and in good faith
determine the fair value of such property. The determination of whether any
adjustment is required under this paragraph 8(a)(4), by reason of the sale and
issuance of any Convertible Securities and the amount of such adjustment, if
any, shall be made at such time and not at the subsequent time of issuance of
shares of Common Stock upon the exercise, conversion or exchange of Convertible
Securities.

               (5) Price Per Share. For purposes of this Section 8(a), "Price
Per Share" shall be defined and determined according to the following formula:

                             P      =       R/N

                             where

                             P      =       Price Per Share;

                             R      =       the "Proceeds" received or
                                            receivable by the Company which (x)
                                            in the case of shares of Common
                                            Stock is the total amount received
                                            or receivable by the Company in
                                            consideration for the

<PAGE>   7

                                             issuance and sale of such shares;
                                             (y) in the case of Rights or of
                                             Convertible Securities with respect
                                             to shares of Common Stock, is the
                                             total amount received or receivable
                                             by the Company in consideration for
                                             the issuance and sale of Rights or
                                             such Convertible Securities, plus
                                             the minimum aggregate amount of
                                             additional consideration, other
                                             than the surrender of such
                                             Convertible Securities, payable to
                                             the Company upon exercise,
                                             conversion or exchange thereof; and
                                             (z) in the case of Rights to
                                             subscribe for or purchase such
                                             Convertible Securities, is the
                                             total amount received or receivable
                                             by the Company in consideration for
                                             the issuance and sale of such
                                             Rights plus the minimum aggregate
                                             amount of additional consideration,
                                             other than the surrender of such
                                             Convertible Securities, payable
                                             upon the conversion or exchange or
                                             exercise of such Convertible
                                             Securities; provided that in each
                                             case the proceeds received or
                                             receivable by the Company shall be
                                             the net cash proceeds after
                                             deducting therefrom any
                                             compensation paid or discount
                                             allowed in the sale, underwriting
                                             or purchase thereof by underwriters
                                             or dealers or others performing
                                             similar services; and

                              N     =        the "Number of Shares," which (x)
                                             in the case of Common Stock is the
                                             number of shares issued; and (y) in
                                             the case of Rights or of
                                             Convertible Securities with respect
                                             to shares of Common Stock, is the
                                             maximum number of shares of Common
                                             Stock initially issuable upon
                                             exercise, conversion or exchange
                                             thereof.

                      (6) Minimum Adjustment. No adjustment in the number of
Warrant Shares purchasable hereunder shall be required unless such adjustment
would require an increase or decrease of at least one percent (1%) in the number
of Warrant Shares purchasable upon the exercise of this Warrant; provided that
any adjustments which by reason of this paragraph 8(a)(6) are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment, and provided further that notwithstanding the foregoing, all such
adjustments shall be made no later than three years from the date of the first
event that would have required an adjustment but for this paragraph. All
calculations shall be made to the nearest one-thousandth of a Warrant Share and
the nearest cent.

                      (7) Adjustment in Exercise Price. Whenever the number of
Warrant Shares purchasable upon the exercise of this Warrant is adjusted as
herein provided, the Exercise Price payable upon exercise of this Warrant
immediately prior to such adjustment shall be adjusted by multiplying such
Exercise Price by a fraction, the numerator of which shall be the number of
Warrant Shares purchasable upon the exercise of this Warrant immediately prior
to such adjustment and the denominator of which shall be the number of Warrant
Shares purchasable immediately thereafter.

<PAGE>   8

                      (8) Shares of Common Stock. For all purposes of this
Agreement, the term "shares of Common Stock" shall mean (i) the Common Stock
and/or (ii) any other class of stock resulting from successive changes or
reclassification of such shares consisting solely of changes in par value, or
from par value to no par value, or from no par value to par value. If at any
time, as a result of an adjustment made pursuant to this Section 8(a), the
Holder shall become entitled to purchase any securities of the Company other
than shares of Common Stock, thereafter the number of such other shares so
purchasable upon exercise of a Warrant and the Exercise Price shall be subject
to adjustment from time to time in a manner and on terms substantially identical
to the provisions with respect to the Warrant Shares contained in paragraphs (1)
through (7) above, and the provisions of this Agreement with respect to the
Warrant Shares shall apply on like terms to any such other securities.

                      (9) Expiration of Rights, Etc. Upon the expiration of any
Rights or the expiration of any conversion or exchange rights, if any thereof
shall not have been exercised, the Exercise Price and the number of Warrant
Shares purchasable upon the exercise of this Warrant shall, upon such
expiration, be readjusted and shall thereafter be such as it would have been had
it been originally adjusted (or had the original adjustment not been required,
as the case may be) as if (i) the only shares of Common Stock so issued were the
shares of Common Stock, if any, actually issued or sold upon the exercise of
such Rights or conversion or exchange or exercise rights and (ii) such shares of
Common Stock, if any, were issued or sold for the consideration actually
received by the Company upon such exercise plus the aggregate consideration, if
any, actually received by the Company for the issuance, sale or grant of all of
such Rights or conversion or exchange or exercise rights whether or not
exercised; provided that no such readjustment shall have the effect of
increasing the Exercise Price or decreasing the number of Warrant Shares
purchasable upon the exercise of a Warrant by an amount in excess of the amount
of the adjustment initially made in respect of the issuance, sale or grant of
such Rights or conversion or exchange or exercise rights.

               (b) Voluntary Adjustment by the Company. The Company may, at its
option and at any time during the term of a Warrant, reduce the then current
Exercise Price to any amount deemed appropriate by the Board of Directors.

               (c) Notice of Adjustment. Whenever the number of Warrant Shares
purchasable upon the exercise of a Warrant or the Exercise Price of Warrant
Shares is adjusted as herein provided, the Company shall promptly mail to the
Holder, at the sole expense of the Company by first class mail, postage prepaid,
notice of such adjustment or adjustments and shall prepare and cause to be
executed and delivered an officer's certificate setting forth the number of
Warrant Shares purchasable upon the exercise of such Warrant and the Exercise
Price of Warrant Shares after such adjustment, setting forth a brief statement
of the facts requiring such adjustment and setting forth in reasonable detail
the computations by which such adjustment was made.

               (d) Preservation of Purchase Rights upon Merger or Consolidation.
In case of any consolidation of the Company with or merger of the Company into
another entity, prior to the consummation of such consolidation or merger the
Company and such successor entity shall execute and deliver an agreement, which
shall be binding on the Holder, that the Holder shall have the right upon the
consummation of such consolidation or merger and upon payment of the Exercise
Price in effect immediately prior to such action (after giving effect to any
applicable adjustments under Section 8(a) hereof) to purchase upon exercise of a
Warrant the kind and amount of shares and other securities and property
(including cash) which such Holder would have owned or have been entitled to
receive after the happening of such consolidation or merger had such Warrant
been exercised immediately prior to such action. The Company shall at its sole
expense mail by first class mail, postage prepaid, to the Holder notice of the
execution of any such agreement. Such agreement shall provide for adjustments,
which shall be substantially identical to the adjustments provided for in this
Section 8. The provisions of this Section 8(d) shall similarly apply to
successive consolidations or mergers.

               (e) Statement on Warrant. Irrespective of any adjustments in the
Exercise Price or the number or kind of shares purchasable upon the exercise of
this Warrant, this Warrant theretofore or thereafter issued may continue to
express the same Exercise Price and number and kind of Warrant Shares as are
stated in this Warrant as initially issued.

               (f) Notices to Holders. In case, at any time or from time to
time:

                      (1) the Company shall authorize the issuance to all
holders of shares of Common Stock of rights, options or warrants to subscribe
for or purchase shares of Common Stock or of any other subscription rights or
warrants; or

                      (2) the Company shall authorize the distribution to all
holders of shares of Common Stock of securities or assets or cash; or

                      (3) of any consolidation or merger to which the Company is
a party and for which approval of any shareholders of the Company is required,
or of the conveyance or transfer of a substantial portion of the assets of the
Company for which approval of any shareholders of the Company is required, or of
any reclassification or change of Common Stock issuable upon exercise of the
Warrants (other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a subdivision or
combination), or a tender offer or exchange offer for shares of Common Stock; or

                      (4) of the voluntary or involuntary dissolution,
liquidation or winding up of the Company; or

                      (5) the Company takes any significant action toward a
public offering or sale of shares of Common Stock (including, without
limitation, the engagement of an investment banking firm, underwriter or other
consultant); or

                      (6) the Company receives a notice from any holder of its
other equity securities that such holder desires to exercise its right to "put"
such securities so held back to the Company;

               then the Company shall cause to be given to the Holder at its
address appearing hereon, at least ten (10) Business Days prior to the
applicable record date hereinafter specified or the date on which a registration
statement relating to such public offering is to be filed with the Securities
and Exchange Commission (the "SEC"), or promptly in the case of events for which
there is no record date, by first class mail, postage prepaid, a written notice
stating (i) the date as of which the holders of record of shares of Common Stock
entitled to receive any such rights, options, warrants or distribution are to be
determined, (ii) the initial expiration date set forth in any tender offer or
exchange offer for shares of Common Stock, (iii) the date on which any such
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding up is expected to become effective or consummated, as
well as the date as of which it is expected that holders of record of shares of
Common Stock shall be entitled to exchange such shares for securities or other
property, if any, deliverable upon such reclassification, consolidation, merger,

<PAGE>   10

conveyance, transfer, dissolution, liquidation, or winding up, (iv) that the
Company intends to proceed with a public offering and notifying the Holder of
the date such registration statement is scheduled to be filed with the SEC, or
(v) the date on which the purchase of shares by the Company is to be effected
pursuant to the exercise of such a put option, together with, in such case, an
officer's certificate stating whether the Company has sufficient funds legally
available to it to make the purchase required in connection with such exercise,
and describing in sufficient detail the calculations made by the Company in
making such statement. The failure to give the notice required by this Section
8(f) or any defect therein shall not affect the legality or validity of any
distribution, right, option, warrant, reclassification, consolidation, merger,
conveyance, transfer, dissolution, liquidation, winding up or action, or the
vote upon any of the foregoing.

        9.     SECURITIES ACT REGISTRATION.

               (a) By acceptance of a Warrant Certificate evidencing the
Warrant, each Holder:

                      (1) represents and agrees that such Holder is acquiring
the Warrant, and that upon exercise thereof it will acquire the Warrant Shares,
with its own funds for its own account for investment, not as a nominee or
agent, and not with a view to any sale, distribution or transfer thereof in
violation of the Securities Act. By acceptance of a Warrant Certificate
evidencing the Warrant, each Holder further represents that it does not have any
contract, undertaking, agreement or arrangement with any person to sell,
transfer, or grant participations to such person or to any third person, with
respect to the Warrant or the Warrant Shares.

                      (2) acknowledges that such Holder has been informed by the
Company or by the previous Holder of the Warrant that the Warrant and any
Warrant Shares obtained upon exercise of any Warrant may not, under the
Securities Act and applicable regulations thereunder, be re-sold, transferred or
otherwise disposed of without registration under the Securities Act or an
applicable exemption from the registration requirements of the Securities Act.

                      (3) acknowledges that the Warrant and any Warrant Shares
obtained upon exercise of any Warrant at the time of issuance may not be
registered under the Securities Act, and applicable state securities laws, on
the ground that the issuance of such securities is exempt pursuant to Section
4(2) of the Act and state law exemptions relating to offers and sales not by
means of a public offering, and that the Company's reliance on such exemptions
is predicated on the undersigned's representations set forth herein.

                      (4) acknowledges that an investment in the Company is
highly speculative and represents that the Holder is able to fend for itself in
the transactions contemplated by this Warrant Agreement, has such knowledge and
experience in financial and business matters as to be capable of evaluating the
merits and risks of its investments, and has the ability to bear the economic
risks (including the risk of a total loss) of its investment. Each Holder
represents that it has had the opportunity to ask questions of the Company
concerning the Company's business and assets and to obtain any additional
information which it considered necessary to verify the accuracy of or to
amplify the Company's disclosures, and has had all questions which have been
asked by it satisfactorily answered by the Company.

               (b) As of the date hereof, the parties hereto have executed and
delivered the Registration Rights Agreement pursuant to which the Warrant Shares
shall be considered Registrable Securities (as defined therein). The parties
agree that the Registration Rights Agreement shall govern all matters relating
to the registration of the Warrant Shares under the Securities Act.

        10.    INFORMATION COVENANTS.

               (a) Notice of Shareholder Meetings. Nothing contained in this
Agreement shall be construed as conferring upon any Holder the right to vote or
to consent to or receive notice as a shareholder in respect of the

<PAGE>   11

meetings of shareholders or the election of directors of the Company or any
other matter, or any rights whatsoever as a shareholder of the Company;
provided, however, that if a meeting of the shareholders of the Company is
called or if consents of the Company's shareholders are solicited to consider
and take action on a proposal for (i) the declaration of a dividend with respect
to the Common Stock, other than in cash, (ii) the voluntary dissolution of the
Company, or (iii) any consolidation, merger or sale of all or substantially all
of its property, assets, business and good will as an entirety, then the Company
shall cause a notice thereof to be sent by first class mail, postage prepaid, at
least five (5) Business Days prior to the record date for determining
shareholders entitled to vote at such meeting or to take action with respect to
such consent, to each Holder of Warrants at such Holder's address appearing on
the Warrant Register.

               (b) Cooperation. The Company shall cooperate with the Holder and
each holder of Warrant Shares in supplying such information as may be reasonably
necessary for such holders to complete and file any information reporting forms
presently or hereafter required by the SEC and any state securities agency as a
condition to the availability of an exemption under the Securities Act and any
applicable state securities law for the sale of this Warrant or any Warrant
Shares.

               (c) Proper Books and Records. The Company covenants that it will
keep proper books and records in which full, true and correct entries in
conformity with generally accepted accounting principles shall be made of all
dealings and transactions in relation to its business and activities.

        11.    REPRESENTATIONS AND WARRANTIES.

the Registration Rights Agreement (collectively, the "Transaction Documents"),
the Company represents and warrants to Maden Tech as of the date hereof as
follows:

               (a) Validity of Securities. The Warrants, when issued and
delivered in accordance with the terms of this Agreement, and the Warrant Shares
issued upon exercise of the Warrants when issued, paid for and delivered in
accordance with the terms of this Agreement and the Warrant Certificates, shall
be duly and validly issued and outstanding, fully paid and nonassessable, not
subject to the preemptive rights of any shareholder and free from all taxes,
liens, security interests, charges, and other encumbrances with respect to the
issuance thereof, other than taxes in respect of any transfer occurring
contemporaneously with such issuance, other than the transfer and other

of the Company's capital stock have been duly authorized and validly issued and
are fully paid and nonassessable, are not subject to the preemptive rights of
any shareholder, have been issued in compliance with all applicable federal and
state securities laws and are free from all taxes, liens, security interests,
charges, and other encumbrances with respect to the issuance thereof, other than
taxes in respect of any transfer occurring contemporaneously with such issuance.

               (b) Registration Rights. Except for parties to the Registration
Rights Agreement and as set forth on Schedule 11(b) hereto, no Person has any
right to cause the Company to effect the registration under the Securities Act
of any securities of the Company.

               The Company shall not be required to issue fractions of Warrant
Shares on the exercise of Warrants. If the Company elects not to issue fractions
of Warrant Shares, then with respect to any fraction of a Share that would

Current Market Price of such fractional Share.

        14.    SURVIVAL.

               This Agreement shall survive the exercise of the Warrants.

        15.    NO IMPAIRMENT; NECESSARY ACTIONS.

               The Company shall not by any action (including, without
limitation, amending its articles of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action) avoid or seek to avoid the
observance or performance of any of the terms of this Agreement or any Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder against

<PAGE>   13

impairment. Without limiting the generality of the foregoing, the Company will:
(a) use its commercially reasonable efforts to obtain all such authorizations,
approvals, exemptions or consents from any Governmental Authority having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Agreement (including, without limitation, making all
necessary filings with such Governmental Authorities, except that the Company
shall not be required to make any such filings as would cause it to be required
to qualify to do business in any such jurisdiction where it would not otherwise
be required to so qualify); (b) take all necessary steps (including, without
limitation, making appropriate amendments to its certificate of incorporation)
to ensure that the Company has authorized a sufficient number of authorized but
unissued shares of its common stock to provide for the issuance of the Warrant
Shares; (c) reserve from such authorized but unissued shares of common stock a
sufficient number of shares to provide for the issuance of the Warrant Shares
upon the exercise of any and all Warrants issued pursuant to this Agreement; and
(d) take all actions as may be necessary or appropriate to ensure that the
Company may validly and legally issue fully paid and non-assessable shares of
Common Stock upon the exercise of any such Warrant that are not subject to any
preemptive rights and are free from all taxes, liens, security interests,
charges, and other encumbrances with respect to the issuance thereof, other than
taxes in respect of any transfer occurring contemporaneously with such issuance.

        16.    ENTIRE AGREEMENT.

               This Agreement constitutes the entire agreement between the
Company and the Holder with respect to this Warrant; provided, that the Company
and the Holder are parties to the Registration Rights Agreement, and the
provisions thereof are deemed incorporated into this Agreement as if the
provisions thereof were originally set forth in full in this Agreement. The
provisions of the Registration Rights Agreement shall be binding on the Holder
without giving effect to any amendment or modification of the Registration
Rights Agreement, unless such amendments or modifications shall have been made
pursuant to the provisions of such Registration Rights Agreement.

        17.    BINDING EFFECT; BENEFITS.

               This Agreement shall inure to the benefit of and shall be binding
upon the Company and the Holder and their respective permitted successors and
assigns. Nothing in this Agreement, expressed or implied, is intended to or
shall confer on any person other than the Company and the Holder, or their
respective permitted successors or assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement.

        18.    SECTION AND OTHER HEADINGS.

               The section and other headings contained in this Agreement are
for reference purposes only and shall not be deemed to be a part of this
Agreement or to affect the meaning or interpretation of this Agreement.

        19.    SEVERABILITY.

               Any term or provision of this Agreement which is invalid or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such invalidity or unenforceability without rendering invalid
or unenforceable the terms and provisions of this Agreement or affecting the
validity or enforceability of any of the terms or provisions of this Agreement
in any other jurisdiction.

        20.    RIGHTS TO CASH DIVIDENDS; NO OTHER RIGHTS OR LIABILITIES AS
               SHAREHOLDER.

               Notwithstanding anything to the contrary in this Agreement,
during the Exercise Period, the Company may not declare and pay any cash
dividends to holders of its Common Stock unless the Company pays to each Holder
a cash dividend in an amount equal to that which such Holder would have received

               THIS CERTIFIES THAT for value received, Maden Tech Consulting,

provided in the Warrant Agreement (as hereinafter defined) up to 2,000,000 fully
paid and nonassessable Shares of the voting common stock (the "Common Stock"),
of Enlighten Software Solutions, Inc., a California corporation (the "Company"),
at the purchase price per Share equal to the Current Market Price as defined in
the Warrant Agreement (the "Exercise Price") upon presentation and surrender of
this Warrant Certificate with the Form of Election to Purchase attached hereto
duly executed. As provided in the Warrant Agreement, the number and kind of
Shares which may be purchased upon the exercise of the Warrant evidenced by this
Warrant Certificate, and the Exercise Price at which such shares are
purchasable, are, upon the happening of certain events, subject to modification
and adjustment.

               This Warrant Certificate and the Warrant it represents are
subject to, and entitled to the benefits of, all of the terms, provisions and
conditions of a certain Warrant Agreement dated as of March 6, 2001 (the
"Warrant Agreement") between the Company and Maden Tech Consulting, Inc., which
Warrant Agreement is hereby incorporated herein by reference and made a part
hereof and to which Warrant Agreement reference is hereby made for a full

               Subject to the terms of the Warrant Agreement, this Warrant
Certificate, upon surrender at the principal office of the Company, may be
exchanged for another Warrant Certificate or Warrant Certificates of like tenor

               No fractional Shares of Common Stock need be issued upon the
exercise of any Warrant evidenced hereby, but in lieu thereof a cash payment may
be made, as provided in the Warrant Agreement.

               During the Exercise Period, the Company may not declare and pay
any cash dividends to holders of its Common Stock, unless the Company pays to
the holder of this Warrant Certificate a cash dividend in an amount equal to
that which such holder would have received had such holder's Warrants been
exercised immediately prior to the record date with respect to such dividend for
the number of Warrant Shares for which its Warrants would have been then
exercisable. No holder of this Warrant Certificate shall be entitled to vote or
receive

dividends (other than as described in the preceding sentence) or be deemed the
holder of Common Stock or any other securities of the Company which may at any
time be issuable on the exercise hereof for any purpose, nor shall anything
contained in the Warrant Agreement or herein be construed to confer upon the
holder hereof, as such, any of the rights of a shareholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
shareholders at any meeting thereof, to give or withhold consent to any
corporate action (whether upon any recapitalization, issue of stock,
reclassification of stock, change of par value or change of stock to no par
value, consolidation, merger, conveyance or otherwise), to receive notice of
meetings (except as provided in the Warrant Agreement), or to receive dividends
or subscription rights or otherwise, until the Warrant evidenced by this Warrant
Certificate shall have been exercised and the Common Stock purchasable upon the
exercise thereof shall have become deliverable as provided in the Warrant
Agreement.
