                                     WARRANT

          To purchase shares of common stock, $.01 par value per share
                              ("Common Stock"), of

                                PEGASYSTEMS INC.
                                 (the "Company")

THIS CERTIFIES that, for value received, and subject to the terms and conditions
set forth in this warrant (the "Warrant"), [________] (the "Holder") or its
registered successors and assigns is entitled to purchase:

                  (i) [______ (____)] fully paid and nonassessable shares of
         Common Stock (the "Initial Warrant Shares"); and

                  (ii) the Additional Warrant Shares (as hereinafter defined).

Subject to the terms and conditions set forth herein, this Warrant shall be
exercisable, in whole or in part, at any time after the earlier to occur of (i)
receipt by the Holder of the Earnout Notice (as hereinafter defined) or (ii) the
closing of a merger or consolidation between the Company and another corporation
or other entity (other than a merger between the Company and a wholly owned
subsidiary of the Company or a merger or consolidation in which the Company is
the surviving corporation) or a sale of all or substantially all of the
Company's consolidated assets. In any event, this Warrant may not be exercised
later than 5:00 p.m., Eastern Standard Time on ______ __, 2012 (the "Expiration
Date"). If not exercised prior to the Expiration Date, this Warrant shall
terminate and shall be of no further force and effect.



         1. Purchase Agreement; Earnout.

                  1.1 Purchase Agreement. This Warrant is issued pursuant to
         that certain Asset Purchase Agreement dated as of January 29, 2002 by
         and among the Company, 1Mind Corporation, 1Mind.com, LLC and the
         Company Equity Holders named therein, as amended from time to time (the
         "Purchase Agreement"). Capitalized terms used herein but not defined
         shall have the meanings ascribed to them in the Purchase Agreement.

                  1.2 Earnout Notice. After the amount of the Earnout
         Consideration, if any, has been finally determined in accordance with
         the Purchase Agreement (including the amount of any setoffs or
         deductions therefrom), the Company shall deliver to the Holder a notice
         in the form attached hereto as Exhibit A (the "Earnout Notice") at the
         address set forth below the Holder's name on the signature page hereof.

                  1.3 Additional Warrant Shares. This Warrant shall be
         exercisable for an additional number of fully paid and nonassessable
         shares of Common Stock (the "Additional Warrant Shares") equal to the
         product obtained by multiplying (a) the Total Additional Warrant Shares
         (as hereinafter defined) by (b) the Applicable Multiple (as hereinafter
         defined). The per share value of such Additional Warrant Shares shall
         be deemed to be equal to the average of the last reported sale prices
         per share of Common Stock on the Nasdaq National Market over the ten
         consecutive trading days ending on the third trading day prior to the
         Earnout Payment Date, subject to equitable adjustment in the event of
         any stock split, stock dividend, reverse stock split or similar event
         affecting the Common Stock.

                  1.4 Certain Definitions.

                  "Applicable Multiple" shall mean an amount equal to the
         quotient obtained by dividing (y) the number of Initial Warrant Shares
         by (z) [_________] (the total number of initial warrant shares subject
         to the Warrant issued to the Company at Closing - to be determined at
         the Closing).

                  "Total Additional Warrant Shares" shall mean that number of
         shares of Common Stock as shall have a value equal to the Warrant
         Holder Earnout Consideration. The value of such Total Additional
         Warrant Shares shall be determined in accordance with the second
         sentence of Section 1.3 hereof.

                  "Warrant Holder Earnout Consideration" shall mean the product
         obtained by multiplying (i) 17.782% by (ii) an amount equal to the
         Earnout Consideration (after giving effect to any setoffs or deductions
         therefrom pursuant to Section 1.10 and Section 6.5(b) of the Purchase
         Agreement).

         2. Exercise.

                  2.1 Cash Exercise. This Warrant may be exercised, in whole or
         in part, by the surrender of this Warrant certificate (with a duly
         completed and executed


                                       2



         notice of exercise in the form attached hereto as Exhibit B) at the
         principal office of the Company (or at such other office or agency of
         the Company as it may designate by notice in writing to the registered
         holder hereof at such holder's last address appearing on the books of
         the Company) and upon payment to the Company by a check payable to the
         order of the Company in an amount calculated by multiplying the number
         of shares of Common Stock for which the Warrant is then being exercised
         by the Exercise Price. As used herein, "Exercise Price" shall mean an
         amount equal to the quotient obtained by dividing (a) the sum of (i)
         [_________] (the total number of initial warrant shares subject to the
         Warrant issued to the Company at Closing - to be determined at the
         Closing) plus (ii) the Total Additional Warrant Shares, by (b)
         [$______] (the aggregate exercise price of all Company Options - to be
         determined at the Closing). The certificate(s) for such shares of
         Common Stock shall be delivered to the registered holder hereof as soon
         as practicable but in any event, not later than fifteen (l5) days after
         the Warrant shall have been so exercised and a new Warrant certificate
         evidencing the number of shares of Common Stock, if any, remaining
         unexercised under the Warrant shall also be issued to the registered
         holder within such period of time unless the Warrant has expired. The
         registered holder of the Warrant evidenced by this certificate shall
         have all the rights of a holder of Common Stock to be issued upon
         exercise of the Warrant when such registered holder tenders payment of
         the Exercise Price to the Company along with this Warrant certificate
         duly endorsed in accordance with this Section 2. No fractional shares
         of Common Stock, or scrip for any such fractional shares, shall be
         issued upon any exercise of the Warrant; but the holder hereof shall be
         entitled to cash equal to such fraction multiplied by the then
         effective Fair Market Value (as hereinafter defined).

                  2.2 Cashless Exercise. In lieu of exercising this Warrant, the
         registered holder hereof may elect at any time after this Warrant has
         become exercisable in accordance with Section 2.1 up through and
         including the Expiration Date to receive shares of Common Stock equal
         to the value of this Warrant (or the portion thereof being cancelled)
         by surrender of this Warrant certificate (with a duly completed and
         executed notice of exercise in the form attached hereto as Exhibit B)
         at the principal office of the Company (or at such other office or
         agency of the Company as it may designate by notice in writing to the
         registered holder hereof at such holder's last address appearing on the
         books of the Company), in which event the Company shall issue to the
         holder hereof a number of shares of Common Stock computed using the
         following formula:

                                X = Y (A - B)
                                    ---------
                                       A

         Where:

                  X = The number of shares of Common Stock to be issued to the
         registered holder upon exercise.

                  Y = The number of shares of Common Stock purchasable under
         this Warrant (or upon the portion thereof being cancelled).


                                       3



                  A = The Fair Market Value of one share of Common Stock.

                  B = Exercise Price (as adjusted to the date of such
         calculations).

                  For purposes of this Section, "Fair Market Value" of the
         Common Stock shall mean the average of the closing bid and asked prices
         of the Common Stock quoted in the over-the-counter market summary or
         the closing sales price per share quoted on any exchange on which the
         Common Stock is listed, whichever is applicable, as published in the
         Eastern Edition of The Wall Street Journal for the ten (10) consecutive
         trading days ending on the third trading day prior to the date of
         determination of Fair Market Value. If the Common Stock is not then
         traded over-the-counter or on an exchange, the Fair Market Value shall
         be determined in good faith by the Board of Directors of the Company.

                  2.3 Adjustment in Exercise Price and Number of Shares. Prior
         to the Expiration Date, the Exercise Price shall be subject to
         adjustment from time to time as hereinafter provided. Upon each
         adjustment of the Exercise Price pursuant to Sections 3.1 or 3.2
         hereof, the holder of this Warrant shall thereafter be entitled to
         purchase at the Exercise Price resulting from such adjustment, the
         number of shares obtained by dividing (1) the product of (x) the number
         of shares purchasable pursuant hereto immediately prior to such
         adjustment and (y) the Exercise Price immediately preceding such
         adjustment by (2) the Exercise Price resulting from such adjustment.

         3. Adjustments.

                  3.1 Stock Dividends. If at any time while this Warrant is
         outstanding the Company shall declare a dividend or make any other
         distribution upon any class or series of stock of the Company payable
         in Common Stock or securities convertible into or exercisable for
         Common Stock, the Exercise Price shall be adjusted, from and after the
         date of determination of stockholders entitled to receive such dividend
         or distribution, to that price determined by multiplying the Exercise
         Price in effect immediately prior to such date of determination by a
         fraction (a) the numerator of which shall be the total number of shares
         of Common Stock outstanding immediately prior to such dividend or
         distribution (assuming the conversion, exchange or exercise of all
         securities convertible into, exchangeable for or exercisable for Common
         Stock), and (b) the denominator of which shall be the total number of
         shares of Common Stock outstanding immediately after such dividend or
         distribution (assuming the conversion, exchange or exercise of all
         securities convertible into, exchangeable for or exercisable for Common
         Stock).

                  3.2 Subdivision or Combination of Stock. If and whenever the
         Company shall at any time subdivide its outstanding shares of Common
         Stock into a greater number of shares, the Exercise Price in effect
         immediately prior to such subdivision shall be proportionately reduced,
         and conversely, in case the outstanding shares of Common Stock of the
         Company shall be combined into a smaller number of shares,


                                       4



         the Exercise Price in effect immediately prior to such combination
         shall be proportionately increased.

                  3.3 Recapitalizations. If at any time or from time to time
         there shall be any capital reorganization or reclassification of the
         capital stock of the Company, consolidation or merger of the Company
         with another corporation (other than a consolidation or merger in which
         the Company is the surviving corporation and which does not result in
         any reclassification of the Common Stock) (any such event being
         referred to herein as a "Recapitalization") provision shall be made so
         that the registered holders shall thereafter be entitled to receive
         upon exercise of the Warrant the number of shares of stock or other
         securities of the Company or otherwise, to which a holder of Common
         Stock deliverable upon exercise of the Warrant would have been entitled
         on such Recapitalization. In any such case, appropriate adjustment
         shall be made in the application of the provisions of this Section 3
         with respect to the rights of the holders of the Warrant after the
         Recapitalization to the end that the provisions of this Section 3
         (including adjustment of the Exercise Price then in effect and the
         number of shares for which the Warrant may be exercised) shall be
         applicable after that event in as nearly an equivalent manner as may be
         practicable.

         4. Company to Provide Stock. The Company covenants and agrees that all
shares of Common Stock which may be issued upon the exercise of the Warrant,
evidenced hereby, upon due exercise of the Warrant, will be duly authorized,
validly issued fully paid and nonassessable and free from all taxes, liens and
charges with respect to the issue thereof to the registered holder hereof other
than those which the Company shall promptly pay or discharge. The Company
further covenants and agrees that during the period within which the Warrant
evidenced hereby may be exercised, the Company will at all times reserve such
number of shares of Common Stock as may be sufficient to permit the exercise in
full of the Warrants.

         5. Other Notices. If any time prior to the Expiration Date:

                  (a) The Company shall declare any dividend on the Common
         Stock; or

                  (b) The Company shall authorize the issue of any options,
         warrants or rights pro rata to all holders of Common Stock entitling
         them to subscribe for or purchase any shares of stock of the Company or
         to receive any other rights; or

                  (c) The Company shall authorize the distribution pro rata to
         all holders of Common Stock of evidences of its indebtedness or assets
         (including cash dividends or distributions paid out of retained
         earnings or retained surplus); or

                  (d) There shall occur any reclassification of the Common
         Stock, or any consolidation or merger of the Company with or into
         another


                                       5



         corporation (other than a consolidation or merger in which the Company
         is the surviving corporation and which does not result in any
         reclassification of the Common Stock) or a sale or transfer to another
         corporation of all or substantially all of the consolidated assets of
         the Company; or

                  (e) There shall occur the voluntary or involuntary
         liquidation, dissolution or winding up of the affairs of the Company;

then and in each of such cases, the Company shall mail to the registered holder
hereof at its last address appearing on the books of the Company, as promptly as
practicable but in any event at least twenty days prior to the applicable record
date (or determination date) mentioned below, a notice stating to the extent
such information is available, (i) the date on which a record is to be taken for
the purpose of such dividend, distribution or rights, or, if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution or rights are to be determined, or (ii)
the date on which such liquidation, dissolution or winding up is expected to
become effective and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, liquidation, dissolution or winding up.

         6. Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant certificate, and in the case of any such loss, theft or destruction of
any Warrant certificate, on delivery of an indemnity agreement or security
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, on surrender and cancellation of such Warrant certificate,
unless the Company has received notice that any such Warrant has been acquired
by a bona fide purchaser, the Company at its expense will execute and deliver,
in lieu thereof, a new Warrant certificate of like tenor.

         7. Registered Holder. The registered holder of this Warrant
certificate, as registered with the Company, shall be deemed the owner hereof
and of the Warrants evidenced hereby for all purposes. The registered holder of
this Warrant certificate shall not be entitled by virtue of ownership of this
Warrant certificate to any rights whatsoever as a stockholder of the Company.

         8. Amendments and Waivers. Any provision in this Warrant certificate to
the contrary notwithstanding, changes to this Warrant certificate may be made
and compliance with any covenant or provision herein set forth may be omitted or
waived if the Company shall obtain consent thereto in writing from the Company
Equity Holder Representative (as defined in the Purchase Agreement).

         9. Transfer.

                  9.1 No Transfer Prior to Receipt of Earnout Notice. Except as
         provided in Section 1.8(c)(ii) of the Purchase Agreement, this Warrant
         may not be sold,


                                       6



         assigned, transferred, pledged, hypothecated or otherwise disposed of
         until after receipt by the Holder of the Earnout Notice.

                  9.2 General. Subject to the provisions of Section 9.1 above,
         this Warrant and the shares of Common Stock issued upon exercise hereof
         may not be transferred or assigned without compliance with applicable
         federal and state securities laws by the transferor and the transferee
         and in accordance with the legend appearing on the face of this Warrant
         (including the delivery of investment representation letters and legal
         opinions reasonably satisfactory to the Company). Any transferee of
         this Warrant shall be bound by the terms hereof. Subject to the
         provisions of this Section 9, title to this Warrant may be transferred
         in the same manner as a negotiable instrument transferable by
         endorsement and delivery with a properly executed assignment (in the
         form of Exhibit C hereto) at the principal office of the Company (or at
         such other office or agency of the Company as it may designate by
         notice in writing to the registered holder hereof at such holder's last
         address appearing on the books of the Company).

                            [Signature page follows]


                                       7



         IN WITNESS WHEREOF, this Warrant has been executed as an instrument
under seal as of the date first set forth above.
