ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

            On September 30, 1999, Accrue Software, Inc., a Delaware corporation
(the "Company"), acquired Marketwave Corporation, a Washington corporation
("Target"), by the statutory merger (the "Merger") of Marketwave Acquisition
Corp., a Washington corporation and a wholly-owned subsidiary of the Company
("Merger Sub"), with and into Target. The Merger was accomplished pursuant to an
Agreement and Plan of Merger and Reorganization, dated as of September 14, 1999,
among the Company, Merger Sub, Target and the shareholders of Target (the
"Merger Agreement") and a related Agreement of Merger (collectively, the "Merger
Agreements"). As a result of the Merger, the Company became the owner of 100% of
the issued and outstanding shares of Target's Common Stock and each outstanding
share of Target Common Stock was converted into 0.1858 shares of the Company's
Common Stock.

        A total of approximately 3,446,414 shares of the Company's Common Stock
will be issued to former Target shareholders and optionholders in exchange for
the acquisition by the Company of all outstanding Target capital stock and all
unexpired and unexercised options to acquire Target capital stock. The shares
issued to Target shareholders were issued pursuant to an exemption from the
registration requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and, accordingly, constitute "restricted securities" within
the meaning of the Securities Act. Target options to purchase Target Common
Stock were assumed by the Company and remain outstanding as options to purchase
shares of the Company's Common Stock. The Company has granted certain
registration rights for the shares issued in connection with the Merger.

        Under the terms of the Merger Agreement and a related Escrow Agreement
dated September 30, 1999, ten percent of the shares of the Company's Common
Stock issued in connection with the Merger will be held in escrow for the
purpose of indemnifying the Company, Merger Sub, and each of their respective
affiliates, officers, directors, employees, representatives and agents against
any damages that relate to or arise from a breach of any of Target's
representations and warranties contained in the Merger Agreement. Such escrow
will expire on the earlier of (i) the date of the issuance of the audit report
on the first financial statements of the Company containing combined operations
of Target and the Company and (ii) September 30, 2000.

        In connection with the Merger, certain employees of Target entered into
noncompetition agreements with the Company, which agreements restrict the
ability of such persons to compete with Target or the Company during the period
commencing on the effective date of the Merger and ending on the later of (a)
two years after the effective date of the Merger and (b) one year after the date
of such person's termination of employment with the Company.

        Effective upon the closing of the Merger, Steven Podradchik, an
executive officer of Target, was appointed as a member of the Company's Board of
Directors.

        For accounting purposes, the Merger will be accounted for as a "pooling
of interests".


<PAGE>   3

        The number of shares of the Company's Common Stock to be issued to the
shareholders of Target was determined by arm's-length negotiations among the
parties.

        Target is a developer and licensor of e-business intelligence and Web
mining software products that allow Internet marketers and Web developers to
identify and analyze how their Internet/Intranet presence is being used by
visitors. The Company intends to continue to use the assets acquired to conduct
such business.

                               AGREEMENT AND PLAN
                          OF MERGER AND REORGANIZATION

        THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("AGREEMENT") is
made and entered into as of September 14, 1999 by and among: ACCRUE SOFTWARE,
INC., a Delaware corporation ("PARENT"); MARKETWAVE ACQUISITION CORP., a
Washington corporation and a wholly owned subsidiary of Parent ("MERGER SUB");
MARKETWAVE CORPORATION, a Washington corporation (the "COMPANY"); and the
holders of all the outstanding capital stock of the Company (the
"SHAREHOLDERS"). Certain other capitalized terms used in this Agreement are
defined in Exhibit A.

                                    RECITALS

        A. Parent, Merger Sub and the Company intend to effect a merger of
Merger Sub with and into the Company in accordance with this Agreement and the
Washington Business Corporation Act (the "MERGER"). Upon consummation of the
Merger, Merger Sub will cease to exist, and the Company will become a wholly
owned subsidiary of Parent.

        B. It is intended that the Merger qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "CODE"). For accounting purposes, it is intended that the Merger be
treated as a "pooling of interests."

        C. This Agreement has been approved by the respective boards of
directors of Parent, Merger Sub and the Company.

        D. The Shareholders own a total of (i) 8,398,845 shares of the Common
Stock (par value $.001 per share) of the Company ("COMPANY COMMON STOCK"), (ii)
2,352,950 shares of the Series A Preferred Stock (par value $.001 per share) of
the Company ("SERIES A PREFERRED STOCK"), and (iii) 4,558,822 shares of the
Series B Preferred Stock (par value $.001 per share) of the Company ("SERIES B
PREFERRED STOCK" and, together with the Company Common Stock and the Series A
Preferred Stock, the "COMPANY STOCK"), which shares are all of the issued and
outstanding shares of capital stock of the Company.

                                    AGREEMENT

        For good and valuable consideration, the receipt of which is hereby
acknowledged, the parties to this Agreement agree as follows: SECTION 1.
DESCRIPTION OF TRANSACTION

        1.1 MERGER OF MERGER SUB INTO THE COMPANY. Upon the terms and subject to
the conditions set forth in this Agreement, at the Effective Time (as defined in
Section 1.3), Merger Sub shall be merged with and into the Company and the
separate existence of Merger Sub shall cease. The Company will continue as the
surviving corporation after the Merger (the "SURVIVING CORPORATION").

        1.2 EFFECT OF THE MERGER. The Merger shall have the effects set forth in
this Agreement and in the applicable provisions of the Washington Business
Corporation Act.

        1.3 CLOSING; EFFECTIVE TIME. The consummation of the transactions
contemplated by this Agreement (the "CLOSING") shall take place at the offices
of Orrick, Herrington & Sutcliffe LLP, 400 Capitol Mall, Suite 3000, Sacramento,
California 95814 at 10:00 a.m. on September 30, 1999, or at such other time and
date as Parent and the Company may agree. The



<PAGE>   8

date on which the Closing actually takes place is referred to in this Agreement
as the "Closing Date." Contemporaneously with or as promptly as practicable
after the Closing, a properly executed agreement of merger conforming to the
requirements of Chapter 23B.11 of the Washington Business Corporation Act shall
be filed with the Secretary of State of the State of Washington. The Merger
shall become effective at the time such agreement of merger is filed with the
Secretary of State of the State of Washington (the "EFFECTIVE TIME").

        1.4 ARTICLES OF INCORPORATION AND BYLAWS; DIRECTORS AND OFFICERS. Unless
otherwise determined by Parent and the Company prior to the Effective Time:

            (a) the Articles of Incorporation of the Surviving Corporation shall
be amended and restated as of the Effective Time to conform to Exhibit B;

            (b) the Bylaws of the Surviving Corporation shall be amended and
restated as of the Effective Time to conform to the Bylaws of Merger Sub as in
effect immediately prior to the Effective Time; and

            (c) the directors and officers of the Surviving Corporation
immediately after the Effective Time shall be the individuals identified on
Exhibit C.

        1.5 CONVERSION OF SHARES.

            (a) Subject to Section 1.8(c), at the Effective Time, by virtue of
the Merger and without any further action on the part of Parent, Merger Sub, the
Company or any Shareholder:

                (i) each share of Company Common Stock outstanding immediately
prior to the Effective Time (including the shares of Company Common Stock issued
upon conversion of all shares of the Company's Series A Preferred Stock and
Series B Preferred Stock) shall be converted into the right to receive the
"Applicable Fraction" (as defined in Section 1.5(b)) of a share of the common
stock (par value $.001 per share) of Parent ("PARENT COMMON STOCK"); and

                (ii) each share of the common stock (par value $.001 per share)
of Merger Sub outstanding immediately prior to the Effective Time shall be
converted into one share of common stock of the Surviving Corporation.

            (b) For purposes of this Agreement:

                (i) the "APPLICABLE FRACTION" shall be calculated by dividing
the Net Merger Shares (as defined below) by the aggregate number of outstanding
shares of Company Common Stock (after giving effect to the conversion of all
outstanding shares of the Company's Series A Preferred Stock and Series B
Preferred Stock into Common Stock) plus the aggregate number of shares
represented by Company Options (as defined in Section 1.6), in each case as of
the Effective Time;


                                      -2-
<PAGE>   9

                (ii) the term "TOTAL MERGER SHARES" shall mean 3,479,375 shares
of Parent Common Stock;

                (iii) the term "NET MERGER SHARES" shall mean the Total Merger
Shares less the number of Expense Shares (as defined below); and

                (iv) the term "EXPENSE SHARES" shall mean the number of shares
of Parent Common Stock calculated by dividing the amount of the Company Expenses
reflected on the Schedule of Expenses delivered pursuant to Section 7.5(j) (less
$300,000 of the Broadview Expenses (as defined in Section 2.22) and all
accounting and legal fees and expenses incurred by the Company in connection
with the transactions contemplated by this Agreement and reflected on the
Schedule of Expenses) by the Stipulated Value (as defined in Section 1.8(c)).

            (c) The Applicable Fraction shall be adjusted to reflect fully the
effect of any stock split, stock dividend (including any dividend or
distribution of stock convertible into Parent Common Stock or Company Common
Stock), reorganization, recapitalization or other similar change with respect to
Parent Common Stock or Company Common Stock after the date hereof and prior to
the Effective Time.

            (d) If any shares of Company Common Stock outstanding immediately
prior to the Effective Time are unvested or are subject to a repurchase option,
risk of forfeiture or other condition under any applicable restricted stock
purchase agreement or other agreement with the Company after giving effect to
any provisions providing for acceleration as a result of the Merger contained in
any applicable restricted stock agreement or other agreement with the Company,
then the shares of Parent Common Stock issued in exchange for such shares of
Company Common Stock will also be unvested and subject to the same repurchase
option, risk of forfeiture or other condition, and the certificates representing
such shares of Parent Common Stock may accordingly be marked with appropriate
legends.

        1.6 EMPLOYEE STOCK OPTIONS. At the Effective Time, each stock option
that is then outstanding under the Company's 1997 Stock Option Plan (the
"COMPANY OPTION PLAN"), whether vested or unvested (a "COMPANY OPTION"), shall
be assumed by Parent in accordance with the terms (as in effect as of the date
of this Agreement) of the Company Option Plan and the stock option agreement by
which such Company Option is evidenced. All rights with respect to Company
Common Stock under outstanding Company Options shall thereupon be converted into
rights with respect to Parent Common Stock. Accordingly, from and after the
Effective Time, (a) each Company Option assumed by Parent may be exercised
solely for shares of Parent Common Stock, (b) the number of shares of Parent
Common Stock subject to each such assumed Company Option shall be equal to the
number of shares of Company Common Stock that were subject to such Company
Option immediately prior to the Effective Time multiplied by the Applicable
Fraction, rounded down to the nearest whole number of shares of Parent Common
Stock (collectively, the "OPTION SHARES"), (c) the per share exercise price for
the Parent Common Stock issuable upon exercise of each such assumed Company
Option shall be determined by dividing the exercise price per share of Company
Common Stock subject to such Company Option, as in effect immediately prior to
the Effective Time, by the Applicable


                                      -3-
<PAGE>   10

Fraction, and rounding the resulting exercise price up to the nearest whole
cent, and (d) all restrictions on the exercise of each such assumed Company
Option shall continue in full force and effect, and the term, exercisability,
vesting schedule and other provisions of such Company Option shall otherwise
remain unchanged; provided, however, that each such assumed Company Option
shall, in accordance with its terms, be subject to further adjustment as
appropriate to reflect any stock split, reverse stock split, stock dividend,
recapitalization or other similar transaction effected by Parent after the
Effective Time. The Company and Parent shall take all action that may be
necessary (under the Company Option Plan and otherwise) to effectuate the
provisions of this Section 1.6. It is the intention of the parties that the
Company Options assumed by Parent qualify following the Effective Time as
incentive stock options as defined in Section 422 of the Code to the extent such
Company Options qualified as incentive stock options prior to the Effective
Time, and this Section 1.6 shall be interpreted consistent with such intent.
Following the Closing, Parent will send to each holder of an assumed Company
Option a written notice setting forth (i) the number of shares of Parent Common
Stock subject to such assumed Company Option, and (ii) the exercise price per
share of Parent Common Stock issuable upon exercise of such assumed Company
Option. No later than February 1, 2000, Parent shall file a registration
statement on Form S-8 for the shares of Parent Common Stock issuable with
respect to assumed Company Options that are eligible for inclusion on Form S-8
and shall maintain the effectiveness of such registration statement thereafter
for so long as any such options or other rights remain outstanding.

        1.7 CLOSING OF THE COMPANY'S TRANSFER BOOKS. At the Effective Time,
holders of certificates representing shares of the Company's capital stock that
were outstanding immediately prior to the Effective Time shall cease to have any
rights as shareholders of the Company and the stock transfer books of the
Company shall be closed with respect to all shares of such capital stock
outstanding immediately prior to the Effective Time. No further transfer of any
such shares of the Company's capital stock shall be made on such stock transfer
books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any of such shares of the Company's capital
stock (a "COMPANY STOCK CERTIFICATE") is presented to the Surviving Corporation
or Parent, such Company Stock Certificate shall be canceled and shall be
exchanged as provided in Section 1.8.

        1.8 EXCHANGE OF CERTIFICATES.

            (a) At or as soon as practicable after the Effective Time, Parent
will send to the holders of Company Stock Certificates (i) a letter of
transmittal in customary form and containing such provisions as Parent may
reasonably specify, and (ii) instructions for use in effecting the surrender of
Company Stock Certificates in exchange for certificates representing Parent
Common Stock. Upon surrender of a Company Stock Certificate to Parent for
exchange, together with a duly executed letter of transmittal and such other
documents as may be reasonably requested by Parent, the holder of such Company
Stock Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of whole shares of Parent Common Stock (and
cash in lieu of any fractional share of Parent Common Stock in accordance with
Section 1.8(c)) that such holder has the right to receive pursuant to the
provisions of this Section 1, and the Company Stock Certificate so surrendered
shall be canceled. Until


                                      -4-
<PAGE>   11

surrendered as contemplated by this Section 1.8, each Company Stock Certificate
shall be deemed, from and after the Effective Time, to represent only the right
to receive upon such surrender a certificate representing shares of Parent
Common Stock (and cash in lieu of any fractional share of Parent Common Stock in
accordance with Section 1.8(c)) as contemplated by this Section 1. If any
Company Stock Certificate shall have been lost, stolen or destroyed, Parent may,
in its discretion and as a condition precedent to the issuance of any
certificate representing Parent Common Stock, require the owner of such lost,
stolen or destroyed Company Stock Certificate to provide an appropriate
affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as
indemnity against any claim that may be made against Parent or the Surviving
Corporation with respect to such Company Stock Certificate.

            (b) No dividends or other distributions declared or made with
respect to Parent Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Company Stock Certificate with
respect to the shares of Parent Common Stock represented thereby and no cash
payment in lieu of any fractional share shall be paid to any such holder, until
such holder surrenders such Company Stock Certificate in accordance with this
Section 1.8 (at which time such holder shall be entitled to receive all such
dividends and distributions and such cash payment).

            (c) No fractional shares of Parent Common Stock shall be issued in
connection with the Merger and no certificates for any such fractional shares
shall be issued. In lieu of such fractional shares, any holder of capital stock
of the Company who would otherwise be entitled to receive a fraction of a share
of Parent Common Stock (after aggregating all fractional shares of Parent Common
Stock issuable to such holder) shall, upon surrender of such holder's Company
Stock Certificate(s), be paid in cash the dollar amount (rounded to the nearest
whole cent), without interest, determined by multiplying such fraction by the
closing price per share of Parent Common Stock on The Nasdaq Stock Market (as
reported in The Wall Street Journal, or, if not reported therein, any other
authoritative source) on the business day immediately prior to the Closing Date
(the "STIPULATED VALUE").

            (d) Parent and the Surviving Corporation shall be entitled to deduct
and withhold from any consideration payable or otherwise deliverable to any
holder or former holder of capital stock of the Company pursuant to this
Agreement such amounts as Parent or the Surviving Corporation may be required to
deduct or withhold therefrom under the Code or under any provision of state,
local or foreign tax law. To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the Person to whom such amounts would otherwise have been
paid.

            (e) Neither Parent nor the Surviving Corporation shall be liable to
any holder or former holder of capital stock of the Company for any shares of
Parent Common Stock (or dividends or distributions with respect thereto) or for
any cash amounts if, on or after the expiration of one (1) year after the
Effective Time, such shares are delivered to any public official pursuant to any
applicable abandoned property, escheat or similar law.

        1.9 DISSENTING SHARES.

            (a) Notwithstanding anything to the contrary contained in this
Agreement, any shares of capital stock of the Company that, as of the Effective
Time, are or may become held by a "dissenter" within the meaning of Chapter
23B.13 of the Washington Business Corporation Act shall not be converted into or
represent the right to receive Parent Common Stock in accordance with Section
1.5 (or cash in lieu of fractional shares in accordance with Section 1.8(c)),
and the holder or holders of such shares shall be entitled only to such rights
as may be granted to such holder or holders in Chapter 23B.13 of the Washington
Business Corporation Act; provided, however, that if the status of any such
holder as a "dissenter" shall not be perfected, or if such holder shall lose
his, her or its status as a "dissenter," then, as of the later of the Effective
Time or the time of the failure to perfect such status or the loss of such
status, such shares shall automatically be converted into and shall represent
only the right to receive (upon the surrender of the certificate or certificates
representing such shares) Parent Common Stock in accordance with Section 1.5
(and cash in lieu of fractional shares in accordance with Section 1.8(c)).

            (b) The Company shall give Parent (i) prompt notice of any written
demand received by the Company prior to the Effective Time to require the
Company to purchase shares of capital stock of the Company pursuant to Chapter
23B.13 of the Washington Business Corporation Act and of any other demand,
notice or instrument delivered to the Company prior to the Effective Time
pursuant to the Washington Business Corporation Act, and (ii) the opportunity to
participate in all negotiations and proceedings with respect to any such demand,
notice or instrument. The Company shall not make any payment (unless such
payment is pursuant to a court order in which event the Company shall give
Parent notice of any such court order or request therefor as soon as
practicable) or settlement offer prior to the Effective Time with respect to any
such demand unless Parent shall have consented in writing to such payment or
settlement offer.

        1.10 HOLDBACK SHARES.

            (a) Parent shall establish and maintain an escrow (the "ESCROW
ACCOUNT") comprised of ten percent (10%) of the Net Merger Shares less the
Option Shares (the "HOLDBACK SHARES"). Parent shall designate and appoint U.S.
Stock Transfer Corporation or such other third party escrow agent that is
mutually and reasonably acceptable to Parent and the Shareholders' Agent (as
hereinafter defined) in connection therewith (the "ESCROW AGENT") to serve in
accordance with the Escrow Agreement substantially in the form attached as
Exhibit D hereto (the "ESCROW AGREEMENT") to be entered into among Parent, the
Escrow Agent and the Shareholders' Agent at Closing. Such escrow of the Holdback
Shares shall be maintained for purposes of satisfying claims brought pursuant to
Section 10 and for the period of time set forth in such Section 10.1 (the
"HOLDBACK PERIOD").

            (b) The right to receive the Holdback Shares upon expiration of the
Holdback Period (i) is an integral part of the consideration in the Merger, and
(ii) shall be transferable or assignable only upon submission of evidence of
such transfer or assignment reasonably satisfactory to Parent and the Escrow
Agent. The value of any shares of Parent Common Stock


                                      -6-
<PAGE>   13

ultimately retained by Parent hereunder shall be treated for purposes of this
Agreement as a reduction of the consideration paid to the Shareholders in the
Merger.

        1.11 TAX CONSEQUENCES. For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code. The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

        1.12 ACCOUNTING TREATMENT. For accounting purposes, the Merger is
intended to be treated as a "pooling of interests."

        1.13 FURTHER ACTION. If, at any time after the Effective Time, any
further action is determined by Parent to be reasonably necessary or desirable
to carry out the purposes of this Agreement or to vest the Surviving Corporation
or Parent with full right, title and possession of and to all rights and
property of Merger Sub and the Company, the officers and directors of the
Surviving Corporation and Parent shall be fully authorized (in the name of
Merger Sub, in the name of the Company and otherwise) to take such action.

SECTION 2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE COMPANY
           EXECUTIVES

        The Company and Steve Podradchik and Barry Allen (collectively, the
"COMPANY EXECUTIVES") jointly and severally represent and warrant, to and for
the benefit of the Indemnitees, that, except as set forth in the Company
Disclosure Schedule:

        2.1 DUE ORGANIZATION; NO SUBSIDIARIES; ETC.

            (a) The Company is a corporation duly organized and validly existing
under the laws of the State of Washington and has all necessary corporate power
and authority to: (i) conduct its business in the manner in which its business
is currently being conducted; (ii) own and use its assets in the manner in which
its assets are currently owned and used; and (iii) perform its obligations under
all Company Contracts.

            (b) The Company has not conducted any business under or otherwise
used, for any purpose or in any jurisdiction, any fictitious name, assumed name,
trade name or other name, other than the names "Marketwave" and
"Marketwave.com."

            (c) The Company is not, and has not been required to be, qualified,
authorized, registered or licensed to do business as a foreign corporation in
any jurisdiction other than the jurisdictions identified in Part 2.1(c) of the
Company Disclosure Schedule, except where the failure to be so qualified,
authorized, registered or licensed has not had and could not reasonably be
expected to result in a Company Material Adverse Effect. The Company is in good
standing as a foreign corporation in each of the jurisdictions identified in
Part 2.1(c) of the Company Disclosure Schedule.


                                      -7-
<PAGE>   14

            (d) Part 2.1(d) of the Company Disclosure Schedule accurately sets
forth (i) the names of the members of the Company's board of directors, (ii) the
names of the members of each committee of the Company's board of directors, and
(iii) the names and titles of the Company's officers.

            (e) Except as set forth in Part 2.1(e) of the Company Disclosure

have been no formal meetings or other proceedings of the shareholders of the

Company's articles of incorporation or bylaws, and the Company has not taken any
action that is inconsistent in any material respect with any resolution adopted
by the Company's shareholders, the Company's board of directors or any committee
of the Company's board of directors. The books of account, stock records, minute
books and other records of the Company are accurate, up-to-date and complete in

business practices.

        2.3 CAPITALIZATION, ETC.

            (a) The authorized capital stock of the Company consists of: (i)
22,500,000 shares of Common Stock, of which 8,398,845 shares have been issued

date of this Agreement, and 5,000,000 of which have been designated "Series B
Preferred Stock," of which 4,558,822 shares have been issued and are outstanding
as of the date of this Agreement. Each outstanding share of Series A Preferred
Stock is convertible into approximately 1.08 shares of Company Common Stock and
each share of Series B Preferred Stock is convertible into one share of Company
Common Stock. All of the outstanding shares of Company Stock have been duly
authorized and validly issued, and are fully paid and non-assessable. Part 2.3
of the Company Disclosure Schedule (i) sets forth the name of each Shareholder
of the Company and the number and type of all shares of Company Common Stock,
Series A Preferred Stock and Series B Preferred Stock held by such Shareholder
and (ii) provides an accurate and complete description of the terms of each

number of shares of Company Common Stock that are subject to such Company Option
and the number of shares of Company Common Stock with respect to which such
Company Option is immediately exercisable; (iii) the date on which such Company
Option was granted and the term of such Company Option; (iv) the vesting
schedule for such Company Option; (v) the exercise price per share of Company
Common Stock purchasable under such Company Option; and (vi) whether such
Company Option has been designated an "incentive stock option" as defined in
Section 422 of the Code. Each Company Option designated as an "incentive stock
option" as defined in Section 422 of the Code on the applicable books and
records of the Company qualified as an "incentive stock option" within the
meaning of Section 422 of the Code on the date of grant of such Company Option.
Except as set forth in Part 2.3(b) of the Company Disclosure Schedule, there is
no: (i) outstanding subscription, option, call, warrant or right (whether or not
currently exercisable) to acquire any shares of the capital stock or other
securities of the Company; (ii) outstanding security, instrument or obligation

            (d) Except as set forth in Part 2.3(d) of the Company Disclosure
Schedule, the Company has never repurchased, redeemed or otherwise reacquired
any shares of capital stock or other securities of the Company. All securities

the date of such filing): (i) each of the Parent's SEC Documents complied in all
material respects with the applicable requirements of the Securities Act or the
Exchange Act, as the case may be, and the rules and regulations promulgated by
the SEC thereunder; and (ii) none of the Parent's SEC Documents contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading.

in the Parent's SEC Documents: (i) complied as to form in all material respects
with the published rules and regulations of the SEC applicable thereto; (ii)
were prepared in accordance with generally accepted accounting principles
applied on a consistent basis throughout the periods covered, except as may be
indicated in the notes to such financial statements and (in the case of
unaudited statements) as permitted by Form 10-Q of the SEC, and except that
unaudited financial statements may not contain footnotes and are subject to
normal and recurring year-end audit adjustments, which will not, individually or
in the aggregate, be material in magnitude; and (iii) fairly present in all
material respects the financial position of Parent as of the respective dates
thereof and the results of operations, shareholders' equity and cash flows of
Parent for the


                                      -29-
<PAGE>   36

periods covered thereby. There has been no material change in Parent's
accounting policies except as described in the notes to the financial statements
included as part of Parent's final Prospectus dated July 30, 1999.

        4.5 ABSENCE OF UNDISCLOSED LIABILITIES. Parent has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the
balance sheet included in Parent's Quarterly Report on Form 10-Q heretofore
provided to the Company for the period ended June 30, 1999 (the "PARENT BALANCE
SHEET"), (ii) those incurred in the ordinary course of business and not required
to be set forth in the Parent Balance Sheet under United States generally
accepted accounting principles, and (iii) those incurred in the ordinary course
of business since the Parent Balance Sheet Date and consistent with past
practice.

        4.6 ABSENCE OF CERTAIN CHANGES. Since June 30, 1999 (the "PARENT BALANCE
SHEET DATE"), Parent has conducted its business in the ordinary course in a
manner consistent with past practice and there has not occurred: (i) any change,
event or condition (whether or not covered by insurance) that has resulted in,
or might reasonably be expected to result in, a Parent Material Adverse Effect;
(ii) any declaration, setting aside, or payment of a dividend or other
distribution with respect to the shares of Parent, or any direct or indirect
redemption, purchase or other acquisition by Parent of any of its shares of
capital stock; (iii) any material amendment or change to Parent's Certificate of
Incorporation or Bylaws; or (iv) any negotiation or agreement by Parent to do
any of the things described in the preceding clauses (i) through (iii) (other
than negotiations with the Company and its representatives regarding the
transactions contemplated by this Agreement).

        4.7 LITIGATION. There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of Parent, threatened
against Parent or any of its subsidiaries or any of their respective properties
or any of their respective officers or directors (in their capacities as such)
that, individually or in the aggregate, could reasonably be expected to have a
Parent Material Adverse Effect. There is no judgment, decree or order against
Parent or any of its subsidiaries or, to the knowledge of Parent or any of its

as such) that could reasonably be expected to prevent, enjoin, or materially
alter or delay any of the transactions contemplated by this Agreement, or that
could reasonably be expected to have a Parent Material Adverse Effect.

        4.8 GOVERNMENTAL AUTHORIZATION. Each of Parent and its subsidiaries has
obtained each federal, state, county, local or foreign governmental consent,
license, permit, grant, or other authorization of a Governmental Body that is
required for the operation of Parent's or any of its subsidiaries' business
("PARENT AUTHORIZATIONS"), and all of such Parent Authorizations are in full
force and effect, except where the failure to obtain or have any of such Parent
Authorizations could not reasonably be expected to have a Parent Material
Adverse Effect.

        4.9 COMPLIANCE WITH LAWS. Each of Parent and its subsidiaries has
complied with, are not in violation of, and have not received any notices of
violation with respect to, any federal,


                                      -30-
<PAGE>   37

state, local or foreign statute, law or regulation with respect to the conduct
of its business, or the ownership or operation of its business, except for such
violations or failures to comply as could not reasonably be expected to have a
Parent Material Adverse Effect.

        4.10 ACCOUNTING AND TAX MATTERS; POOLING OF INTERESTS.

            (a) Parent is not aware of any agreement, plan or other circumstance
that would prevent the Merger from constituting a reorganization under Section
368(a) of the Code.

            (b) Neither Parent nor any of its subsidiaries nor, to the knowledge
of Parent, any of their respective directors, officers or stockholders has taken
any action which would interfere with Parent's ability to account for the Merger
as a "pooling-of-interests."

        4.11 AUTHORITY; BINDING NATURE OF AGREEMENT. Parent and Merger Sub have
the right, power and authority to perform their obligations under this Agreement
and the Related Agreements to which Parent or Merger Sub, as applicable, is a
party and the transactions contemplated hereby and thereby; and the execution,
delivery and performance by each of Parent and Merger Sub of this Agreement, the
Related Agreements to which it is a party and the transactions contemplated
hereby and thereby (including the contemplated issuance of Parent Common Stock
in the Merger in accordance with this Agreement) have been duly authorized by
all necessary corporate action on the part of Parent and Merger Sub, their
respective boards of directors and the shareholder of Merger Sub. No vote of
Parent's Shareholders is required to approve the Merger. This Agreement
constitutes the legal, valid and binding obligation of Parent and Merger Sub,
enforceable against them in accordance with its terms, and the Related
Agreements to which they are a party, when executed and delivered by Parent and
Merger Sub, as applicable, shall be legal, valid and binding obligations of
Parent and Merger Sub, as applicable, enforceable against them in accordance
with their respective terms, in each case subject to (i) laws of general
application relating to bankruptcy, insolvency and the relief of debtors, and
(ii) rules of law governing specific performance, injunctive relief and other
equitable remedies.

        4.12 VALID ISSUANCE. The Merger Shares will, when issued in accordance
with the provisions of this Agreement and the Agreement of Merger, be duly
authorized, validly issued, fully paid and nonassessable and free of preemptive
rights and Encumbrances. Parent owns all the outstanding shares of capital stock

Agreement and that caused or constitutes an inaccuracy in or breach of any
representation or warranty made by the Company or any of the Shareholders in
this Agreement;

                (ii) the discovery by the Company of any event, condition, fact
or circumstance that occurs, arises or exists after the date of this Agreement
and that would cause or constitute an inaccuracy in or breach of any
representation or warranty made by the Company or any of the Shareholders in
this Agreement if (A) such representation or warranty had been made as of the
time of the occurrence, existence or discovery of such event, condition, fact or
circumstance, or (B) such event, condition, fact or circumstance had occurred,

"NOTICE OF BREACH").

            (b) If any event, condition, fact or circumstance that is required

shall execute and deliver to Parent, and the Company shall use all commercially
reasonable efforts to cause each other Person identified on Exhibit E-1 (and any

untrue or inaccurate in any material respect and (ii) any Material Adverse
Change in Parent's business or financial condition, taken as a whole.

        6.9 REORGANIZATION TREATMENT. Neither Parent, the Shareholders nor the
Company shall take any action (either before or after the Closing) that would
cause the Merger to fail to qualify as a reorganization within the meaning of
Section 368(a) of the Code. Parent shall, and shall use its reasonable best
efforts to cause the Surviving Corporation to, report to the extent required by
the Code or the regulations thereunder, the Merger for United States federal

sections 601 through 609 of ERISA and section 4980B of the Code) to employees of
the Company who are terminated


                                      -36-
<PAGE>   43

in connection with the Merger and who elect such coverage notwithstanding
whether such employees are entitled to elect continuation coverage under ERISA
or the Code.

        6.11 SECTION 16 MATTERS. The Board of Directors of Parent shall, to the
extent permitted by applicable law, take or cause to be taken all actions

            (a) the mutual consent of Parent, Merger Sub and the Company; or


                                      -41-
<PAGE>   48

            (b) Parent and Merger Sub if the conditions set forth in Section 7
hereof shall not have been satisfied by October 15, 1999, except if such
conditions have not been satisfied solely as a result of the action or inaction
of Parent or Merger Sub, or such earlier date upon which Parent receives a
Notice of Breach from the Company; or

            (c) the Company if the conditions set forth in Section 8 hereof
shall not have been satisfied by October 15, 1999, except if such conditions
have not been satisfied solely as a result of the action or inaction of the
Company or the Shareholders; or

            (d) Parent and Merger Sub or the Company if, without fault of the
terminating party, there shall be any applicable federal or state law that makes
consummation of the Merger illegal or otherwise prohibited or if any court of
competent jurisdiction or Governmental Body shall have issued an order, decree,
ruling or taken any other action restraining, enjoining or otherwise prohibiting
the Merger and such order, decree, ruling or other action shall have become
final and nonappealable.

Any termination pursuant to this Section 9.1 (other than a termination pursuant
to Section 9.1(a) hereof) shall be effected by written notice from the party or
parties so terminating to the other parties hereto.

        9.2 EFFECT OF TERMINATION. In the event of the termination of this
Agreement as provided in Section 9.1, this Agreement shall be of no further
force or effect, except for this Section 9.2 and Section 11, each of which shall
survive the termination of this Agreement; provided, however, that the liability
of any party for any breach by such party of the representations, warranties,
covenants or agreements of such party set forth in this Agreement occurring
prior to the termination of this Agreement shall survive the termination of this
Agreement.

SECTION 10.  INDEMNIFICATION, ETC.

        10.1 SURVIVAL OF REPRESENTATIONS, ETC.

            (a) The representations and warranties made by the Company and the
Company Executives set forth in Section 2 shall survive the Closing and shall
expire on the earlier of (i) the date of the issuance of the audit report on the
first financial statements of Parent containing combined operations of the
Company and Parent and (ii) the first anniversary of the Closing Date (the
"TERMINATION DATE"); provided, however, that if, at any time prior to the
Termination Date, any Indemnitee (acting in good faith) delivers to the
Shareholders' Agent a written notice alleging the existence of an inaccuracy in
or a breach of any of the representations and warranties made by the Company and
the Company Executives set forth in Section 2 (and setting forth in reasonable
detail the basis for such Indemnitee's belief that such an inaccuracy or breach
may exist) and asserting a claim for recovery under Section 10.2 based on such
alleged inaccuracy or breach, then the claim asserted in such notice shall
survive the Termination Date until such time as such claim is fully and finally
resolved. All representations and warranties made by Parent shall terminate and
expire as of the Closing Date, and any liability of Parent with respect to such
representations and warranties shall thereupon cease.


                                      -42-
<PAGE>   49

            (b) The representations, warranties, covenants and obligations of
Company and the Shareholders, and the rights and remedies that may be exercised
by the Indemnitees, shall not be limited or otherwise affected by or as a result
of any information furnished to, or any investigation made by or knowledge of,
any of the Indemnitees or any of their Representatives.

            (c) For purposes of this Agreement, each statement or other item of
information set forth in the Company Disclosure Schedule shall be deemed to be a
representation and warranty made by the Company and the Shareholders in this
Agreement.

        10.2 INDEMNIFICATION.

            (a) Indemnification by Company Indemnitors. From and after the
Closing Date (but subject to Section 10.1(a)), the Merger Shareholders (the
"INDEMNITORS"), jointly and severally, shall hold harmless and indemnify each of
the Indemnitees from and against, and the Holdback Shares shall be available to
compensate and reimburse each of the Indemnitees for, any Damages that are
directly or indirectly suffered or incurred by any of the Indemnitees or to
which any of the Indemnitees may otherwise become subject (regardless of whether
or not such Damages relate to any third-party claim) and that arise from or as a
result of, or are directly or indirectly connected with: (i) any breach of any
representation or warranty set forth in Section 2 (without giving effect to any
"Company Material Adverse Effect" or other materiality qualification or any
similar qualification contained or incorporated directly or indirectly in such
representation or warranty), or (ii) any Legal Proceeding relating to any breach
of the type referred to in clause (i) above (including any Legal Proceeding
commenced by any Indemnitee for the purpose of enforcing any of its rights under
this Section 10).

            (b) Deductible. The Indemnitors shall not be required to make any
indemnification payment pursuant to Section 10.2(a) for any inaccuracy in or
breach of any representation and warranty set forth in Section 2 until such time
as the total amount of all Damages (including the Damages arising from such
inaccuracy or breach and all other Damages arising from any other inaccuracies
in or breaches of any representations or warranties) that have been directly or
indirectly suffered or incurred by any one or more of the Indemnitees, or to
which any one or more of the Indemnitees has or have otherwise become subject,
exceeds $500,000 in the aggregate. (If the total amount of such Damages exceeds
$500,000, then the Indemnitees shall be entitled to be indemnified against and
compensated and reimbursed for the entire amount of such Damages up to a maximum
of the full amount of the Holdback Shares.)

            (c) Limitation Due to Post-Closing Actions. None of the Indemnitors
shall have any liability for Damages which arise solely as a result of (i)
actions taken by or on behalf of, or omissions of, Parent or the Surviving
Corporation after the Closing; (ii) changes in accounting methods or policies of
the Surviving Corporation after the Closing; or (iii) the passing of, or any
change in, after the Closing, any law or administrative practice of any
Governmental Body in any such case not actually in force as of the date of this
Agreement (even if retroactive in effect), including any increase in the tax
rates in effect on the date of this Agreement or the imposition of any Tax not
in effect on the date of this Agreement.


                                      -43-
<PAGE>   50

        10.3 EXCLUSIVE REMEDY. With the exception of claims based upon fraud,
from and after the Closing, recourse of the Indemnitees to the Holdback Shares
pursuant to this Agreement and the Escrow Agreement shall be the sole and
exclusive remedy of the Indemnitees for monetary damages for any inaccuracy in
or breach of any representation or, warranty contained in Section 2 of this
Agreement or any Legal Proceeding related thereto. Any distribution of Holdback
Shares to satisfy a claim hereunder shall be done so as to reduce the Escrow
Account. Any Holdback Shares remaining upon termination of the Escrow Account
shall be distributed to the Merger Shareholders in accordance with the Escrow
Agreement.

        10.4 NO CONTRIBUTION. No Indemnitors shall have any right of
contribution, right of indemnity or other right or remedy against the Company in
connection with any indemnification obligation or any other liability to which
she, he or it may become subject under or in connection with this Agreement.

        10.5 DEFENSE OF THIRD PARTY CLAIMS. In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against the
Company, Parent or against any other Person) with respect to which any of the
Indemnitors may become obligated to hold harmless, indemnify, compensate or
reimburse any Indemnitee pursuant to this Section 10, Parent shall have the
right, at its election, to proceed with the defense of such claim or Legal
Proceeding on its own. If Parent so proceeds with the defense of any such claim
or Legal Proceeding:

            (a) all reasonable expenses relating to the defense of such claim or
Legal Proceeding by counsel reasonably satisfactory to the Shareholders' Agent
shall be borne and paid exclusively from the Holdback Shares;

            (b) each Indemnitor shall make available to Parent any documents and
materials in his, her or its possession or control that reasonably may be
necessary to the defense of such claim or Legal Proceeding; and

            (c) Parent shall have the right to settle, adjust or compromise such
claim or Legal Proceeding with the written consent of the Shareholders' Agent
(as defined in Section 11.2); provided, however, that such consent shall not be
unreasonably withheld.

Parent shall give the Shareholders' Agent prompt notice of the commencement of
any such Legal Proceeding against Parent or the Company; provided, however, that
any failure on the part of Parent to so notify the Shareholders' Agent shall not
limit any of the obligations of the Indemnitors under this Section 10 (except to
the extent such failure materially prejudices the defense of such Legal
Proceeding). Parent shall conduct the defense of such claim or Legal Proceeding
diligently and in good faith using all reasonable means and defenses available
to it or to the Company. The Shareholders' Agent shall have the right, if it so
notifies Parent with reasonable promptness after receipt of Parent's claim
notice, to assist at its own expense and with counsel of its choice in the
defense of such claim or Legal Proceeding by Parent (or in the case of a claim
or Legal Proceeding against the Company, by the Company). In such event, Parent
shall afford the Shareholders' Agent and its counsel a reasonable opportunity to
comment and the right to object (which right shall not be unreasonably
exercised) with respect to the conduct of the


                                      -44-
<PAGE>   51

defense of such claim or Legal Proceeding. Parent shall keep the Shareholders'
Agent reasonably informed of the progress of any claim or Legal Proceeding and
its defense, and shall with reasonable promptness provide the Shareholders'
Agent with copies of all material notices, written communications and filings
(including court papers) made by or on behalf of any of the parties to the
underlying claim or Legal Proceeding. If Parent does not elect to proceed with
the defense of any such claim or Legal Proceeding, the Shareholders' Agent may
proceed with the defense of such claim or Legal Proceeding with counsel
reasonably satisfactory to Parent; provided, however, that the Shareholders'
Agent may not settle, adjust or compromise any such claim or Legal Proceeding
without the prior written consent of the Parent (which consent may not be
unreasonably withheld).

SECTION 11.  MISCELLANEOUS PROVISIONS

        11.1 RESTRICTIONS ON TRANSFER

            (a) The shares of Parent Common Stock to be issued to each
Shareholder at the Effective Time pursuant to Section 1 of this Agreement and
any shares of capital stock or other securities received with respect thereto
(collectively, the "RESTRICTED SECURITIES") shall not be sold, transferred,
assigned, pledged, encumbered or otherwise disposed of (each, a "TRANSFER")
except upon the conditions specified in this Section 11.1, which conditions are
intended to insure compliance with the provisions of the Securities Act. Each
Shareholder shall observe and comply with the Securities Act and the rules and
regulations promulgated by the SEC thereunder as now in effect or hereafter
enacted or promulgated, and as from time to time amended, in connection with any
Transfer of Restricted Securities beneficially owned by the Shareholder.

            (b) Each certificate representing the Restricted Securities issued
to a Shareholder and each certificate for such securities issued to subsequent
transferees of any such certificate shall (unless otherwise permitted by the
provisions of Sections 11.1(c) and 11.1(d) hereof) be stamped or otherwise
imprinted with a legend in substantially the following form:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
        INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
        1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES OR "BLUE-SKY" LAWS.
        THESE SECURITIES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED,
        ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION
        OR AN EXEMPTION THEREFROM. ADDITIONALLY, THE TRANSFER OF THESE
        SECURITIES IS SUBJECT TO THE CONDITIONS SPECIFIED IN SECTION 11.1 OF THE
        AGREEMENT AND PLAN OF REORGANIZATION DATED AS OF SEPTEMBER 14, 1999
        AMONG ACCRUE SOFTWARE, INC., MARKETWAVE ACQUISITION CORP. AND MARKETWAVE
        CORPORATION AND THE OTHER SIGNATORIES THERETO AND NO TRANSFER OF THESE


                                      -45-
<PAGE>   52

        SECURITIES SHALL BE VALID OR EFFECTIVE UNTIL SUCH CONDITIONS HAVE BEEN
        FULFILLED. UPON THE FULFILLMENT OF CERTAIN OF SUCH CONDITIONS, PUBLIC
        CO, INC. HAS AGREED TO DELIVER TO THE HOLDER HEREOF A NEW CERTIFICATE,
        NOT BEARING THIS LEGEND, FOR THE SECURITIES REPRESENTED HEREBY
        REGISTERED IN THE NAME OF THE HOLDER HEREOF. COPIES OF SUCH AGREEMENT
        MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF
        RECORD OF THIS CERTIFICATE TO THE SECRETARY OF ACCRUE SOFTWARE, INC."

            (c) Each Shareholder agrees, prior to any Transfer of Restricted
Securities, to give written notice to Parent of such Shareholder's intention to
effect such Transfer and to comply in all other respects with the provisions of
this Section 11.1. Each such notice shall describe the manner and circumstances
of the proposed Transfer and shall be accompanied by the written opinion,
addressed to Parent, of counsel for the holder of such Restricted Securities,
stating that in the opinion of such counsel (which opinion and counsel shall be
reasonably satisfactory to Parent) such proposed transfer does not involve a
transaction requiring registration or qualification of such Restricted
Securities under the Securities Act or the securities or "blue-sky" laws of any
relevant state of the United States. The holder thereof shall thereupon, with
the written consent of Parent, be entitled to Transfer such Restricted
Securities in accordance with the terms of the notice delivered by it to Parent.
Each certificate or other instrument evidencing the securities issued upon the
Transfer of any such Restricted Securities (and each certificate or other
instrument evidencing any untransferred balance of such Restricted Securities)
shall bear the legend set forth in Section 11.1(b) unless (x) in such opinion of
counsel of Parent registration of any future Transfer is not required by the
applicable provisions of the Securities Act or (y) Parent shall have waived the
requirement of such legends. No Shareholder shall Transfer any Restricted
Securities until such opinion of counsel has been given (unless waived by Parent
or unless such opinion is not required in accordance with the provisions of this
Section 11.1(c)).

            (d) Notwithstanding the foregoing provisions of this Section 11.1,
the restrictions imposed by this Section 11.1 upon the transferability of
Restricted Securities shall cease and terminate when (i) any such shares are
sold or otherwise disposed of pursuant to an effective registration statement
under the Securities Act or as otherwise contemplated by Section 11.1(c) and,
pursuant to Section 11.1(c), the securities so transferred are not required to
bear the legend set forth in Section 11.1(b) or (ii) the holder of such
Restricted Securities has met the requirements for Transfer of such Restricted
Securities pursuant to Rule 144. Whenever the restrictions imposed by this
Section 11.1 shall terminate, as herein provided, the holder of Restricted
Securities as to which such restrictions have terminated shall be entitled to
receive from Parent, without expense, a new certificate not bearing the
restrictive legend set forth in Section 11.1(b) and not containing any other
reference to the restrictions imposed by this Section 11.1.

            (e) Each Shareholder understands and agrees that Parent, at its
discretion, may cause stop transfer orders to be placed with its transfer agent
with respect to certificates for


                                      -46-
<PAGE>   53

Restricted Securities owned by such Shareholder but not as to certificates for
such shares of Parent Common Stock as to which the legend set forth in this
Section 11.1(b) is no longer required because one or more of the conditions set
forth in Section 11.2(d) shall have been satisfied.

            (f) The provisions of this Section 11.1 shall be in addition to, and
shall not alter or otherwise limit, the provisions set forth in the Affiliate
Agreements.

        11.2 SHAREHOLDERS' AGENT. The Company and the Shareholders hereby
irrevocably appoint Steve Podradchik as their agent and as the agent for the
Indemnitors for purposes of all matters relating to Section 1.9, Section 10 and
the Escrow Agreement (the "SHAREHOLDERS' AGENT"), and Steve Podradchik hereby
accepts his appointment as the Shareholders' Agent. Parent shall be entitled to
deal exclusively with the Shareholders' Agent on all matters relating to Section
1.9, Section 10 and the Escrow Agreement, and shall be entitled to rely
conclusively (without further evidence of any kind whatsoever) on any document
executed or purported to be executed on behalf of any Shareholder or Indemnitor
by the Shareholders' Agent, and on any other action taken or purported to be
taken on behalf of any Shareholder or Indemnitor by the Shareholders' Agent, as
fully binding upon such Shareholder or Indemnitor. If the Shareholders' Agent
shall die, become disabled or otherwise be unable to fulfill his
responsibilities as agent of the Shareholders and Indemnitors, then the
Shareholders shall, within ten days after such death or disability, appoint a
successor agent and, promptly thereafter, shall notify Parent of the identity of
such successor. Any such successor shall become the "Shareholders' Agent" in
accordance with this Section 11.2. If for any reason there is no Shareholders'
Agent at any time, all references herein to the Shareholders' Agent shall be
deemed to refer to the Shareholders. The Shareholders' Agent shall be reimbursed
out of the Holdback Shares for his reasonable out-of-pocket expenses incurred in
connection with serving as the Shareholders' Agent under this Agreement and the
Escrow Agreement. Shareholders' Agent shall not be liable for any act done or
omitted hereunder as Shareholders' Agent while acting in good faith and in the
exercise of reasonable judgment. The Shareholders on whose behalf Holdback
Shares were contributed to the Escrow Account shall severally indemnify
Shareholders' Agent and hold Shareholders' Agent harmless against any loss,
liability or expense incurred without gross negligence, bad faith or willful
misconduct on the part of Shareholders' Agent and arising out of or in
connection with the acceptance or administration of Shareholders' Agent's duties
hereunder and under the Escrow Agreement, including the reasonable fees and
expenses of any legal counsel retained by Shareholders' Agent.

        11.3 FURTHER ASSURANCES. Each party hereto shall execute and cause to be
delivered to each other party hereto such instruments and other documents, and
shall take such other actions, as such other party may reasonably request (prior
to, at or after the Closing) for the purpose of carrying out or evidencing any
of the transactions contemplated by this Agreement.

        11.4 FEES AND EXPENSES. As used in this Agreement, "TRANSACTION COSTS"
shall mean, with respect to any party, all actual, out-of-pocket expenses
incurred by such party to third parties in connection with this Agreement, the
Agreement of Merger, the Related Agreements, the Merger and all other
transactions provided for herein and therein but shall not in any event


                                      -47-
<PAGE>   54

include general overhead; the time spent by employees of such party internally;
postage, telephone, telecopy, photocopy and delivery expenses of such party;
permit and filing fees; and other non-material expenses that are incidental to
the ordinary course of business. Each party hereto shall bear its own
Transaction Costs; provided, however, that in the event the Merger shall be
consummated, the Shareholders shall bear all Transaction Costs of the Company
(other than any severance payments paid by Parent in connection with the
Merger), whether or not such fees and expenses have been paid by the Company on
or before the Closing Date and whether or not such fees and expenses are
reflected in the Company Disclosure Schedule or the Schedule of Expenses (such
Transaction Costs of the Company being herein collectively referred to as the
"COMPANY EXPENSES"), other than $300,000 of the Broadview Expenses and all legal
and accounting fees incurred by the Company in connection with the transactions
contemplated by this Agreement.

        11.5 ATTORNEYS' FEES. If any action or proceeding relating to this
Agreement or the enforcement of any provision of this Agreement is brought
against any party hereto, the prevailing party shall be entitled to recover
reasonable attorneys' fees, costs and disbursements (in addition to any other

                            INVESTOR RIGHTS AGREEMENT

        THIS INVESTOR RIGHTS AGREEMENT (this "Agreement") is entered into as of
September 30, 1999, by and among Accrue Software, Inc., a Delaware corporation
(the "Company"), and the Marketwave Holders (as defined below).

                                    RECITALS

        A. The Company, Marketwave Corporation, a Washington corporation
("Marketwave"), and Marketwave Acquisition Corp., a Washington corporation and a
wholly owned subsidiary of the Company ("Merger Sub"), have entered into an
Agreement and Plan of Merger and Reorganization dated as of September 14, 1999
(the "Merger Agreement") providing for the merger of Merger Sub with and into
Marketwave (the "Merger") and the Merger Agreement contemplates that, upon
consummation of the Merger, (i) holders of shares of the capital stock of
Marketwave (collectively with all holders of Assumed Options that become a party
to this Agreement pursuant to Section 3.10, the "Marketwave Holders") will
receive shares of common stock of the Company ("Common Stock") in exchange for
their shares of capital stock of Marketwave and (ii) Marketwave will become a
wholly owned subsidiary of the Company;

        B. The execution of this Agreement by the Company is a condition to the
obligation of Marketwave and the Marketwave Holders to consummate the
transactions contemplated by the Merger Agreement; and

        C. The Company wishes to execute this Agreement and grant to the
Marketwave Holders the rights contained herein in order to fulfill such
condition.

        THE PARTIES AGREE AS FOLLOWS:

        1. Amendment.

            1.1 Procedure. Except as expressly provided herein, neither this
Agreement nor any term hereof may be amended, waived, discharged or terminated
other than by a written instrument signed by the party against whom enforcement
of any such amendment, waiver, discharge or termination is sought.
Notwithstanding the foregoing, any provision of this Agreement may be amended,
waived, discharged or terminated upon the written consent of the Company and the
holders of at least a majority of the outstanding Registrable Securities (as
defined below); provided, however, that no such amendment shall be effective
with respect to any Holder if such amendment materially adversely affects any of
the rights granted pursuant to this Agreement to such Holder (the "Uniquely
Affected Holder") in a manner different from the manner in which such amendment
affects all other Holders, unless such amendment is consented to in writing by
the Uniquely Affected Holder. If such Holder does not so consent, then the
amendment shall be effective as to all Holders other than the Uniquely Affected
Holder.

<PAGE>   4

            1.2 Rights of Holders. Each Holder (as defined below) shall have the
absolute right to exercise or refrain from exercising any right or rights that
such Holder may have by reason of this Agreement, including, without limitation,
the right to consent to the waiver or modification of any obligation under this
Agreement, and such Holder shall not incur any liability to any other Holder of
any securities of the Company as a result of exercising or refraining from
exercising any such right or rights.

        2. Registration Rights.

            2.1 Definitions. As used in this Agreement:

                (a) The terms "register," "registered," and "registration" refer
to a registration effected by preparing and filing a registration statement in
compliance with the Securities Act of 1933, as amended (the "Securities Act"),
and the subsequent declaration or ordering of the effectiveness of such
registration statement.

                (b) The term "Registrable Securities" means:

                    (i) The shares of Common Stock issued or issuable to the
Marketwave Holders pursuant to the terms of the Merger Agreement; provided,
however, that the Registrable Securities shall not include the Holdback Shares
(as defined in the Merger Agreement) until and unless such shares are released
from the Escrow Agreement (as defined in the Merger Agreement) and provided
further that the Registrable Securities shall not include shares of Common Stock
issued to Marketwave Holders upon the exercise of Assumed Options if such shares
are registered under a registration statement on Form S-8 (the shares of Common
Stock referred to in this clause (i) are collectively referred to hereafter as
the "Stock"); and

                    (ii) Any other shares of Common Stock issued as (or issuable
upon the conversion or exercise of any warrant, right or other security which is
issued as) a dividend or other distribution with respect to, or in exchange for
or in replacement of, the Stock, excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which his or her
rights under this Agreement are not assigned; provided, however, that Common
Stock or other securities shall only be treated as Registrable Securities if and
so long as they have not been (A) sold to or through a broker or dealer or
underwriter in a public distribution or a public securities transaction, or (B)
sold in a transaction exempt from the registration and prospectus delivery
requirements of the Securities Act under Section 4(1) thereof so that all
transfer restrictions, and restrictive legends with respect thereto, if any, are
removed upon the consummation of such sale.

                (c) The number of shares of "Registrable Securities then
outstanding" shall be determined by the number of shares of Common Stock or
other securities outstanding which are, and the number of shares of Common Stock
or other securities issuable pursuant to then exercisable or convertible
securities which are, Registrable Securities.

                (d) The term "Holder" means any holder of outstanding
Registrable Securities who, subject to the limitations set forth in Section 2.13
below, acquired such


                                      -2-
<PAGE>   5

Registrable Securities in a transaction or series of transactions not involving
any registered public offering.

                (e) The term "Form S-3" means such form under the Securities Act
as in effect on the date hereof or any registration form under the Securities
Act subsequently adopted by the Securities and Exchange Commission (the "SEC")
which permits inclusion or incorporation of substantial information by reference
to other documents filed by the Company with the SEC.

            2.2 Requested Registration.

                (a) If, at any time after December 1, 1999, the Company shall
receive a written request from any Holder that the Company file a registration
statement under the Securities Act covering the registration of that number of
shares of Registrable Securities whose anticipated aggregate offering price, net
of underwriting discounts and commissions, would equal at least $10,000,000,
then the Company shall, within ten (10) days of the receipt thereof, give
written notice of such request to all Holders and shall, subject to the
limitations of subsection 2.2(b), effect as soon as practicable, and in any
event within ninety (90) days of the receipt of such request, or, with respect
to any request received by the Company between December 1, 1999 and December 15,
1999, on or prior to February 1, 2000, the registration under the Securities Act
of all Registrable Securities which the Holders request to be registered within
twenty (20) days of the mailing of such notice by the Company in accordance with
Section 3.5.

                (b) If the Holder or Holders initiating the registration request
hereunder ("Initiating Holders") intend to distribute the Registrable Securities
covered by their request by means of an underwriting, they shall so advise the
Company as a part of their request made pursuant to this Section 2.2 and the
Company shall include such information in the written notice referred to in
subsection 2.2(a). The underwriter will be selected by the Company and shall be
reasonably acceptable to a majority in interest of the Initiating Holders. In
such event, the right of any Holder to include his Registrable Securities in
such registration shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting (unless otherwise mutually agreed by a majority in interest of the
Initiating Holders and such Holder) to the extent provided herein. All Holders
proposing to distribute their securities through such underwriting shall
(together with the Company as provided in subsection 2.4(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by a majority in interest of the Initiating
Holders. Notwithstanding any other provision of this Section 2.2, if the
underwriter advises the Initiating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the
Initiating Holders shall so advise all Holders of Registrable Securities which
would otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
allocated among all Holders thereof, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities of
the Company owned by each Holder; provided, however, that the number of shares
of Registrable Securities to be included in such


                                      -3-
<PAGE>   6

underwriting shall not be reduced unless all other securities proposed to be
sold by persons other than the Holders are first entirely excluded from the
underwriting.

                (c) The Company is obligated to effect only two (2) such
registrations pursuant to this Section 2.2.

                (d) Notwithstanding the foregoing, if the Company shall furnish
to Holders requesting a registration statement pursuant to this Section 2.2 a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company and its stockholders for such registration statement
to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
for a period of not more than ninety (90) days after receipt of the request of
the Initiating Holders; provided, however, that the Company may not utilize this
right more than once in any twelve month period.

            2.3 Company Registration. If (but without any obligation to do so)
the Company proposes to register (including for this purpose a registration
effected by the Company for stockholders other than the Holders) any of its
Common Stock or other securities under the Securities Act in connection with the
public offering of such securities solely for cash (other than a registration
relating either to the sale of securities to participants in a Company stock
option, stock purchase or similar plan or to an SEC Rule 145 transaction, or a
registration on any form which does not include substantially similar
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities), the Company shall, at such
time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within fifteen (15) days from receipt of
such notice by the Company in accordance with Section 3.5, the Company shall,
subject to the provisions of Section 2.8, cause to be registered under the
Securities Act all of the Registrable Securities that each such Holder has
requested to be registered.

            2.4 Obligations of the Company. Whenever required under this Section
2 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

                (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and keep such registration statement
effective for one hundred twenty (120) days, or until the distribution
contemplated in the Registration Statement has been completed; provided,
however, that (i) such 120-day period shall be extended for a period of time
equal to the period the Holder refrains from selling any securities included in
such registration at the request of an underwriter of Common Stock (or other
securities) of the Company; and (ii) in the case of any registration of
Registrable Securities on Form S-3 which are intended to be offered on a
continuous or delayed basis, such 120-day period shall be extended, if
necessary, to keep the registration statement effective until all such
Registrable Securities are sold, provided that Rule 415, or any successor rule
under the Securities Act, permits an offering on a continuous or delayed basis,
and provided further that applicable rules under the Securities Act governing
 the


                                      -4-
<PAGE>   7

obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment which (i) includes any prospectus required by Section
10(a)(3) of the Securities Act or (ii) reflects facts or events representing a
material or fundamental change in the information set forth in the registration
statement, the incorporation by reference of information required to be included
in (i) and (ii) above to be contained in periodic reports filed pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the
"1934 Act"), in the registration statement.

                (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                (c) Furnish to the Holders such reasonable numbers of copies of
a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

                (e) In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

                (g) Furnish, at the request of any Holder requesting
registration of Registrable Securities pursuant to this Section 2, on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Section 2, if such securities
are being sold through underwriters, or, if such securities are not being sold
through underwriters, on the date that the registration statement with respect
to such securities becomes effective, (i) an opinion, dated such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated such date, from
the independent public accountants of the Company, in form and substance as is
customarily given


                                      -5-
<PAGE>   8

by independent certified public accountants to underwriters in an underwritten
public offering, addressed to the underwriters, if any, and to the Holders
requesting registration of Registrable Securities.

                (h) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange or automated quotation system
on which similar securities issued by the Company are then listed.

            2.5 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 2 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

            2.6 Expenses of Demand Registration. All expenses other than stock
transfer taxes, the fees and disbursements of special counsel for individual
Holders, underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 2.2, including
(without limitation), all registration, filing and qualification fees, printers
and accounting fees, fees and disbursements of counsel for the Company, and the
reasonable fees and disbursements of one counsel for the selling Holders (not to
exceed $15,000) shall be borne by the Company; provided, however, that the
Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant to Section 2.2 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (in which case all Participating Holders
shall bear such expenses), unless the Holders of a majority of the Registrable
Securities agree to forfeit their right to one demand registration pursuant to
Section 2.2; provided further, however, that if at the time of such withdrawal,
the Holders have learned of a material adverse change in the condition,
business, or prospects of the Company from that known to the Holders at the time
of their request, then the Holders shall not be required to pay any of such
expenses and shall retain their rights pursuant to Section 2.2.

            2.7 Expenses of Company Registration. All expenses, other than stock
transfer taxes, the fees and disbursements of special counsel of individual
Holders, underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 2.3, including
(without limitation), all registration, filing and qualification fees, printers
and accounting fees, fees and disbursements of counsel for the Company, and the
reasonable fees and disbursements of one special counsel for all of the
participating Holders (not to exceed $15,000) shall be paid by the Company.

            2.8 Underwriting Requirements. In connection with any offering
involving an underwriting of shares being issued by the Company, the Company
shall not be required under Section 2.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it, and then
only in such quantity as will not, in the opinion of the underwriters, adversely
affect the success of the offering by the Company. If the total amount of
securities,


                                      -6-
<PAGE>   9

including Registrable Securities, requested by Holders to be included in such
offering exceeds the amount of securities sold other than by the Company that
the underwriters reasonably believe would not adversely affect the success of
the offering, then the Company shall be required to include in the offering only
that number of such securities, including Registrable Securities, which the
underwriters believe will not adversely affect the success of the offering (the
securities so included to be apportioned first to the Company, then pro rata
among the selling Holders and the selling holders participating in such
registration pursuant to the terms of the Second Amended and Restated
Registration Rights Agreement dated as of August 13, 1998 (the "Existing Rights
Agreement") among the Company and the parties listed on the signature pages
thereto according to the total amount of Registrable Securities (including
Registrable Securities as defined in the Existing Rights Agreement) entitled to
be included therein owned by each selling Holder and then to all other selling
stockholders, or in such other proportions as shall mutually be agreed to by
such selling stockholders); it being understood that with respect to any
offering, no exclusion may reduce the total number of Registrable Securities
plus Registrable Securities under the Existing Rights Agreement to less than
twenty-five percent (25%) of the total number of securities subject to the
registration. For purposes of the first parenthetical in the preceding sentence
concerning apportionment, for any selling stockholder which is a holder of
Registrable Securities and which is a partnership or corporation, the partners,
retired partners and stockholders of such holder, or the estates and family
members of any such partners and retired partners and any trusts for the benefit
of any of the foregoing persons shall be deemed to be a single "selling
stockholder," and any pro rata reduction with respect to such "selling
stockholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling stockholder," as defined in this sentence.

            2.9 No Delay of Registration. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 2.

            2.10 Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 2:

                (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Securities
Act) for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the 1934 Act, against
any losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Securities Act, the 1934 Act or other federal or state
law, insofar as such losses, claims, damages, or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement
or alleged untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading, or (iii) any violation
or alleged violation by the Company of the Securities Act, the 1934 Act, any
state securities law or any rule or regulation


                                      -7-
<PAGE>   10

promulgated under the Securities Act, the 1934 Act or any state securities law;
and the Company will pay, as incurred, to each such Holder, underwriter or
controlling person, any legal or other expenses reasonably incurred by them in
connection with defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
2.10(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability, or action if such settlement is effected without the consent
of the Company (such consent not to be unreasonably withheld), nor shall the
Company be liable in any such case for any such loss, claim, damage, liability,
or action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Holder,
underwriter or controlling person.

                (b) To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter,
any other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Securities Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such
Holder will pay, as incurred, any legal or other expenses reasonably incurred by
any person intended to be indemnified pursuant to this subsection 2.10(b) in
connection with defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
2.10(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Holder (such consent not to be unreasonably withheld); provided further,
that in no event shall any indemnity under this Section 2.10(b) exceed the net
proceeds from the offering received by such Holder, except in the case of
willful fraud by such Holder.

                (c) Promptly after receipt by an indemnified party under this
Section 2.10 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.10, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to


                                      -8-
<PAGE>   11

defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.10 (to the extent of such prejudicial
effect), but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 2.10.

                (d) No indemnifying party, in the defense of any claim arising
out of a Violation, shall, except with the consent of each indemnified party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such indemnified party of a release from all liability in respect to such
claim or litigation and, in the event the terms of such judgment or settlement
include any term other than the payment by the indemnifying party of money
damages, the indemnifying party shall not so consent or enter into such a
settlement without the consent of each indemnified party (which will not be
unreasonably withheld) whether or not the terms thereof include such a release.

                (e) The obligations of the Company and Holders under this
Section 2.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 2, and otherwise.

                (f) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

            2.11 Reports Under Securities Exchange Act of 1934. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

                (a) Make and keep public information available, as those terms
are understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the public;

                (b) take such action, including the voluntary registration of
its Common Stock under Section 12 of the 1934 Act, as is necessary to enable the
Holders to utilize Form S-3 for the sale of their Registrable Securities, such
action to be taken as soon as practicable after the end of the fiscal year in
which the first registration statement filed by the Company for the offering of
its securities to the general public is declared effective;

                (c) File with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the 1934 Act; and

                (d) Furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied


                                      -9-
<PAGE>   12

with the reporting requirements of SEC Rule 144 (at any time after ninety (90)
days after the effective date of the first registration statement filed by the
Company), the Securities Act and the 1934 Act (at any time after it has become
subject to such reporting requirements), or that it qualifies as a registrant
whose securities may be resold pursuant to Form S-3 (at any time after it so
qualifies), (ii) a copy of the most recent annual or quarterly report of the
Company and such other reports and documents so filed by the Company, and (iii)
such other information as may be reasonably requested in availing any Holder of
any rule or regulation of the SEC which permits the selling of any such
securities without registration.

            2.12 Form S-3 Registration. In case the Company shall receive from
any Holder or Holders (the "S-3 Initiating Holders") a written request or
requests that the Company effect a registration on Form S-3 and any related
qualification or compliance with respect to all or a part of the Registrable
Securities owned by such Holder or Holders, the Company will:

                (a) promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders; and

                (b) as soon as practicable, effect such registration and all
such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all or such portion of such Holder's
or Holders' Registrable Securities as are specified in such request, together
with all or such portion of the Registrable Securities of any other Holder or
Holders joining in such request as are specified in a written request given
within fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance pursuant to this Section 2.12 (1) if
Form S-3 is not available for such offering by the Holders; (2) if the Holders,
together with the holders of any other securities of the Company entitled to
inclusion in such registration, propose to sell Registrable Securities and such
other securities (if any) at an aggregate price to the public (net of any
underwriters' discounts or commissions) of less than $1,500,000; (3) if the
Company shall furnish to the Holders a certificate signed by the President of
the Company stating that in the good faith judgment of the Board of Directors of
the Company it would be seriously detrimental to the Company and its
stockholders for such Form S-3 Registration to be effected at such time, in
which event the Company shall have the right to defer the filing of the Form S-3
registration statement for a period of not more than sixty (60) days after
receipt of the request of the Holder or Holders under this Section 2.12;
provided, however, that the Company shall not utilize this right more than once
in any twelve month period; (4) at any time during the twelve (12) month period
following the Company's July 30, 1999 initial public offering; (5) if the
Company has, within the twelve (12) month period preceding the date of such
request, already effected one registration on Form S-3 for the Holders pursuant
to this Section 2.12; or (6) in any particular jurisdiction in which the Company
would be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance.
Notwithstanding any other provision of this Section 2.12, if the Company or an
underwriter advising the Company advises the S-3 Initiating Holders in writing
that marketing factors require a limitation of the number of shares to be
included in any registration on Form S-3, then the S-3 Initiating Holders shall
so advise all Holders of Registrable Securities which would otherwise be
included in such registration on


                                      -10-
<PAGE>   13

Form S-3 hereunder, and the number of shares of Registrable Securities that may
be included in the registration shall be allocated among all Holders thereof,
including the S-3 Initiating Holders, in proportion (as nearly as practicable)
to the amount of Registrable Securities of the Company owned by each Holder;
provided, however, that the number of shares of Registrable Securities to be
included in such registration shall not be reduced unless all other securities
proposed to be sold by persons other than the Holders are first entirely
excluded from the registration.

                (c) Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. All expenses other than stock transfer
taxes, the fees and disbursements of special counsel for individual Holders,
underwriting discounts and commissions incurred in connection with a
registration requested pursuant to Section 2.12, including (without limitation)
all registration, filing, qualification, printer's and accounting fees and the
reasonable fees and disbursements of counsel for the selling Holder or Holders
(not to exceed $15,000) and counsel for the Company, shall be borne by the
Company; provided, however, that the Company shall not be required to pay for
any expenses of any registration proceeding begun pursuant to this Section 2.12
if the registration request is subsequently withdrawn at the request of the
Holders of a majority of the Registrable Securities to be registered (in which
case all Participating Holders shall bear such expenses); provided further,
however, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business, or prospects of the Company
from that known to the Holders at the time of their request, then the Holders
shall not be required to pay any of such expenses and shall retain their rights
pursuant to this Section 2.12. Registrations effected pursuant to this Section
2.12 shall not be counted as demands for registration or registrations effected
pursuant to Section 2.2 or 2.3.

                (d) The Company is obligated to effect only five (5) such
registrations on Form S-3 pursuant to this Section 2.12.

            2.13 Assignment of Registration Rights. The rights to cause the
Company to register Registrable Securities pursuant to this Section 2 may only
be assigned by a Holder to a transferee who acquires at least 250,000 shares of
Registrable Securities (subject to appropriate adjustment for any stock split,
reverse stock split, stock dividend, recapitalization or similar transaction),
provided the Company is, prior to such transfer, furnished with written notice
of the name and address of such transferee; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Securities Act. The foregoing 250,000 share requirement
shall not apply, however, to any transferee which is a partner, retired partner
or affiliated or constituent partnership of any Holder which is a partnership,
(including spouses and ancestors, lineal descendants and siblings of such
partners or spouses who acquire Registrable Securities by gift, will or
intestate succession) or which is a family member (including a spouse, ancestor,
lineal descendant or sibling) or a trust for the benefit of any individual
Holder, if all such transferees or assignees agree in writing to be bound by the
terms of this Agreement and appoint a single representative as their attorney in
fact for the purpose of receiving any notices and exercising their rights under
this Section 2.

            2.14 Termination of Registration Rights. No Holder shall be entitled
to exercise any right provided for in this Agreement (a) after August 4, 2004 or
(b) at such time as such Holder may sell all of such Holder's Registrable
Securities in any single three (3) month period pursuant to Rule 144 (or such
successor rule as may be adopted).

FOR IMMEDIATE RELEASE

ACCRUE AND MARKETWAVE ANNOUNCE AGREEMENT TO MERGE, FURTHER STRENGTHENING
POSITION IN THE ENTERPRISE EBUSINESS ANALYSIS MARKET

MARKETWAVE ADDS SIGNIFICANTLY TO ACCRUE'S EMPLOYEE TALENT, TECHNOLOGY, CUSTOMER
BASE AND DISTRIBUTION CHANNELS

FREMONT, CALIF., -- SEPTEMBER 15, 1999 -- Accrue Software(TM), Inc., (NASDAQ:
ACRU), a leading provider of eBusiness analysis software and services, today
announced that it has signed a definitive agreement to merge with Marketwave
Corporation, a privately held company that develops the Hit List(R) family of
scalable solutions for analyzing Web traffic on Internet and intranet sites.
Upon closing of the transaction, Marketwave will become a wholly owned
subsidiary of Accrue Software. Specific terms of the agreement were not
released; however, Marketwave's outstanding stock will be exchanged for
approximately 3.5 million shares of Accrue common stock. The closing, which is
subject to certain customary closing conditions, is expected to occur on or
prior to September 30, 1999.

"We saw tremendous synergy between Marketwave's technology and expertise and our
own. By combining the two companies, Accrue will be a more powerful player in
the Web site eBusiness analysis market with critical mass of customers,
employees and revenue," said Richard Kreysar, president and CEO of Accrue. "The
merger provides five key benefits: broadest platform coverage, clear technology
leadership, outstanding people, an exceptional referencable customer list and
expanded worldwide sales channels."

"Accrue's Insight is the eBusiness analysis leader in the Solaris world, and
Marketwave's Hit List is the leader in the Windows NT world," said Steve
Podradchik, founder and CEO of Marketwave, who will take a seat on Accrue's
board of directors. "Combined, the two companies create a very strong unified
force in the market, being the leading vender of Web site analysis solutions."

The combined company will have more than 300 enterprise-class customers.
Marketwave brings Ask Jeeves, Broadcast.com, Buy.com, Citibank, Compaq, Dell,
Egghead.com, IBM, and Shopping.com. Coupled with Accrue's stellar customer list
of companies with significant Web initiatives that includes Oracle Corporation,
Preview Travel, Hearst New Media, Bank of America, ShopNow.com and
TheStreet.com, Accrue becomes the worldwide leader in number of customers for
enterprise eBusiness analysis applications.

The merger also expands the platform and database options from which customers
can choose to include Microsoft Windows NT and Sun Solaris operating systems
with SQL Server, DB2, Informix/Redbrick or Oracle databases.

"With this merger, Accrue now offers the most platform and database choices for
enterprise eBusiness analysis, as well as one of the largest customer bases in
the industry," said Kreysar. "Our expanded engineering, sales and customer
service efforts will be focused on Accrue Insight, Hit List Live and Hit List
Enterprise, all of which are aimed at the high-end market of companies with
significant Web initiatives and visitor traffic."
