         THE SECURITIES REPRESENTED BY THIS CERTIFICATE AND ISSUABLE UPON
         EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"), OR UNDER THE PROVISIONS OF ANY
         APPLICABLE STATE SECURITIES LAWS, BUT HAVE BEEN ACQUIRED BY THE
         REGISTERED HOLDER HEREOF FOR PURPOSES OF INVESTMENT AND IN RELIANCE ON
         STATUTORY EXEMPTIONS UNDER THE SECURITIES ACT, AND UNDER ANY APPLICABLE
         STATE SECURITIES LAW. THESE SECURITIES AND THE SECURITIES ISSUED UPON
         EXERCISE HEREOF MAY NOT BE SOLD, PLEDGED, TRANSFERRED OR ASSIGNED, NOR
         MAY THIS WARRANT BE EXERCISED, EXCEPT IN ACCORDANCE WITH TERMS SET

         PROVISIONS OF THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES
         LAWS OR PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT; AND IN THE
         CASE OF AN EXEMPTION, ONLY IF THE COMPANY HAS RECEIVED AN OPINION OF
         COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH TRANSACTION DOES NOT
         REQUIRE REGISTRATION OF ANY SUCH SECURITIES.

                             ADAYTUM SOFTWARE, INC.

                          COMMON STOCK PURCHASE WARRANT

               ADAYTUM SOFTWARE, INC., a Delaware corporation (the
"Company"), hereby agrees that, for value received, Dyadic Systems Limited
(the "Holder") or assigns, is entitled, subject to the terms set forth below,
to purchase from the Company at any time or from time to time after the date
hereof and before 5:00 p.m., Central Standard Time, on June 8, 2007, Twelve
Thousand Five Hundred (12,500) shares of the common stock of the Company,
$0.01 par value (the "Common Stock"), at a price per share of $4.00 USD,
subject to adjustments as described herein.

               1.  EXERCISE OF WARRANT.  The purchase rights exercisable
under this Warrant shall be exercised by the Holder surrendering this Warrant
with the Exercise Form attached hereto duly executed by such Holder, to the
Company at its principal office, accompanied by payment, in cash or by
certified or official bank check payable in USD to the order of the Company,
of the purchase price payable in respect of the Common Stock being purchased.
If less than all of the Common Stock is purchased, the Company will, upon
such exercise, execute and deliver to the Holder hereof a new Warrant (dated
the date hereof) evidencing the number of shares of the Common Stock not so
purchased. As soon as practicable after the exercise of this Warrant and
payment of the purchase price, the Company will cause to be issued in the
name of and delivered to the Holder hereof, or as such Holder may direct
(subject to the provisions of Section 3 below), a certificate or certificates
representing the shares purchased upon such exercise. The Company may require
that such certificate or certificates contain on the face thereof a legend
substantially as follows:


                                       1
<PAGE>


               "The transfer of the shares represented by this certificate is
               restricted pursuant to the terms of a Common Stock Purchase
               Warrant dated April __, 2000, issued by Adaytum Software,
               Inc., a copy of which is available for inspection at the
               offices of Adaytum, Inc. Transfer may not be made except in
               accordance with the terms of the Common Stock Purchase
               Warrant. In addition, no sale, offer to sell or transfer of
               the shares represented by this certificate shall be made
               unless a Registration Statement under the Securities Act of
               1933, as amended, and applicable state laws with respect to
               such shares is then in effect or exemptions from the
               registration requirements of such Act and applicable state
               laws are available."

               No fractional shares of Common Stock are to be issued upon the
exercise of this Warrant, but the Company shall pay a cash adjustment in
respect of any fraction of a share which would otherwise be issuable in an
amount equal to the same fraction of the fair market value per share of
Common Stock on the day of exercise as determined in good faith by the
Company, less the exercise price that would have otherwise been paid for such
fractional share. The shares purchased on exercise of this Warrant shall be
deemed to be issued as of the close of business on the date on which this
Warrant has been exercised by payment of the purchase price. The exercise of
this Warrant or any portion hereof shall only be effective at such time that
the issuance and sale of shares of the Company's Common Stock pursuant to
such exercise will not violate any applicable securities or other laws.

                    1.1. EXERCISE UPON LIQUIDATING EVENT. This Warrant will,
without any decision or action from the Holder, be exercised under this
Section 1 upon a Liquidating Event and upon the following conditions:

                             1.1.1. EVENT NOTICE. The Company will give the
Holder at least 30 days' prior notice describing such Liquidating Event, the
consideration to be received by holders of Common Stock, the anticipated
closing date of such Liquidating Event (the "Anticipated Closing Date") and
other information reasonably required to decide whether to exercise or
forfeit the Warrant.

                             1.1.2. FORFEIT NOTICE. Investor will instead
forfeit the Warrant if Investor gives the Company notice of its intent to
forfeit at least five days before the Anticipated Closing Date.

                             1.1.3. LIQUIDATING EVENT DEFINED. "Liquidating
Event," as such term is used in this Warrant, means (1) the sale of all or
substantially all of the Company's securities or assets to a non-affiliate of
the Company; (2) a public offering of Common Stock which is registered with
the Securities and Exchange Commission; or (3) any transaction,


                                       2
<PAGE>


including without limitation the closing of an offering of securities of the
Company, which results upon its closing in a net cash inflow to the Company
of at least $20,000,000.00 USD.

               2.  ADJUSTMENT OF PURCHASE PRICE, REORGANIZATION, ETC.  In the
event the Company shall at any time hereafter subdivide or combine its
outstanding shares of Common Stock, or declare a dividend payable in Common
Stock, the exercise price in effect immediately prior to the subdivision,
combination or record date for such dividend payable in Common Stock shall
forthwith be proportionately increased, in the case of combination, or
proportionately decreased, in the case of subdivision or declaration of a
dividend payable in Common Stock, and each share of Common Stock purchasable
upon exercise of this Warrant shall be changed to the number determined by
dividing the then current exercise price by the exercise price as adjusted
after such subdivision, combination or dividend payable in Common Stock.

               In the event of any capital reorganization or any
reclassification of the shares of Common Stock of the Company, or in the case
of any consolidation with or merger of the Company into or with another
corporation, or the sale of all or substantially all of its assets to another
corporation effected in such a manner that the holders of common shares shall
be entitled to receive stock, securities or assets with respect to or in
exchange for Common Stock, then, as a part of such reorganization,
reclassification, consolidation, merger or sale, as the case may be, lawful
provision shall be made so that the Holder of this Warrant shall have the
right thereafter to receive, upon the exercise hereof, the kind and amount of
shares of stock or other securities or property which the Holder would have
been entitled to receive if, immediately prior to such reorganization,
reclassification, consolidation, or merger or sale, the Holder had held the
number of shares of Common Stock which were then purchasable upon the
exercise of this Warrant. In any such event, appropriate adjustment (as
determined in good faith by the Board of Directors of the Company) shall be
made in the application of the provisions set forth herein with respect to
the rights and interest thereafter of the Holder of this Warrant, to the end
that the provisions set forth herein (including provisions with respect to
adjustments of the exercise price) shall thereafter be applicable, as nearly
as reasonably may be, in relation to any shares of stock or other property
thereafter deliverable upon the exercise of this Warrant.

               3.  TRANSFERABILITY; SECURITIES LAWS MATTERS.  Neither the
issuance and sale of this Warrant nor the issuance and sale of shares of
Common Stock of the Company issuable upon exercise of this Warrant have been
registered under the Securities Act of 1933, as amended (the "Securities
Act"), or any state securities laws. Prior to making any disposition of this
Warrant or of any Common Stock purchased or purchasable upon exercise of this
Warrant, the Holder will give written notice to the Company describing
briefly the manner of any such proposed disposition. The Holder will not make
any such disposition until (i) the Company has notified the Holder that, in
the opinion of its counsel, registration under the Securities Act and
applicable state laws is not required with respect to such disposition, or
(ii) appropriate registrations covering the proposed disposition have been
filed by the Company


                                       3
<PAGE>

and have become effective. The Company agrees that, upon receipt of written
notice from a Holder with respect to such proposed transfer or disposition,
it will use its best efforts, in consultation with such Holder's counsel, to
ascertain as promptly as possible whether or not registration is required and
will advise the Holder promptly with respect thereto.

               The Company has no obligation to file any registrations under
the Securities Act, as amended, or applicable state laws, nor in the event of
any such registration, to include this Warrant or the shares of Common Stock
purchased or purchasable hereunder in any such registration statement.

               The Company shall have no obligation to recognize any transfer
of this Warrant or the Common Stock purchased upon exercise of this Warrant
which is not made in compliance with this provision. Until the Warrant or the
Common Stock purchased hereunder is transferred on the books of the Company,
the Company may treat the Holder as the absolute owner hereof and thereof for
all purposes without being affected by any notice to the contrary.

               Holder hereby represents and agrees that any securities
acquired upon exercise of this Warrant will be acquired for long-term
investment purposes and not with the view toward distribution or sale thereof
in a public offering within the meaning of the Securities Act.

               4. RESERVATION OF COMMON STOCK. A number of shares of Common
Stock sufficient to provide for the exercise of the Warrant upon the basis
herein set forth shall at all times be reserved for the exercise thereof.

               5. NO RIGHTS AS STOCKHOLDER. This Warrant shall not entitle
the Holder to any voting rights or other rights as a stockholder of the
Company.

               6. MISCELLANEOUS. The Company will not, by amendment of its
Certificate of Incorporation or through reorganization, consolidation,
merger, dissolution or sale of assets, or by any other voluntary act or deed,
avoid or seek to avoid the observance or performance of any of the covenants,
stipulations or conditions to be observed or performed hereunder by the
Company, but will at all times in good faith assist, insofar as it is able,
in the carrying out of all provisions hereof and in the taking of any other
action which may be necessary in order to protect the rights of the Holder
hereof.

               The provisions of Section 3 hereof shall survive the exercise
of this Warrant.

               All shares of Common Stock or other securities issued upon the
exercise of the Warrant shall be validly issued, fully paid and nonassessable.

               Neither this Warrant nor any term hereof may be changed,
waived, discharged or terminated orally, but only by an instrument in writing
signed by the party against which enforcement of the change, waiver,
discharge or termination is sought.

               IN WITNESS WHEREOF this Warrant been duly executed by Adaytum
Software, Inc., the 8th day of June, 2000.
