                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:  WHAT IS THE MERGER? (PAGE 50)

     A:  The merger is the combination of two businesses, Broadbase and
         Servicesoft, which will result in Servicesoft becoming a wholly-owned
         subsidiary of Broadbase. Based on the exchange ratio of 1.4404 and the
         capitalization of Broadbase and Servicesoft as of September 30, 2000,
         Servicesoft stockholders before the merger will own approximately 34.7%
         of Broadbase after the merger, and Broadbase stockholders before the
         merger will own approximately 65.3% of Broadbase after the merger, on a
         fully-diluted basis.

Q:  WHY ARE BROADBASE AND SERVICESOFT PROPOSING TO MERGE? (PAGES 53 AND 55)

     A:  Broadbase and Servicesoft are proposing to merge because we believe the
         combination of our two companies will enable us to:

          - address increasing market demand for a more complete software
            solution;

          - respond more quickly and effectively to technological change,
            increased competition and market demands;

          - more effectively sell and market our products and services;

          - increase market penetration by selling both companies' software
            solutions through both companies' sales and distribution channels;
            and

          - accelerate the growth of our combined businesses.

Q:  WHAT WILL SERVICESOFT STOCKHOLDERS RECEIVE IN THE MERGER? (PAGE 68)

     A:  Servicesoft stockholders will receive 1.4404 shares of Broadbase common
         stock for each share of Servicesoft common stock and preferred stock
         that they own, including each share of Servicesoft common stock and
         preferred stock received upon conversion of the exchangeable common
         stock and exchangeable preferred stock of Servicesoft Canada. No
         fractional shares will be issued, but Servicesoft stockholders will
         receive cash for any fractional shares that they would otherwise
         receive. For example, if you own 100 shares of Servicesoft common
         stock, you will receive 144 shares of Broadbase common stock in
         exchange for your Servicesoft shares, and an amount of cash equal to
         0.04 times the market price of a share of Broadbase common stock as of
         the closing date of the merger.

Q:  WHAT WILL HAPPEN IF THE TRADING PRICE OF BROADBASE COMMON STOCK CHANGES?

     A:  The number of shares of Broadbase common stock to be issued for each
         share of Servicesoft stock is fixed and will not be adjusted based upon
         changes in the value of Broadbase common stock. As a result, the value
         of the Broadbase shares that Servicesoft stockholders will receive in
         the merger will not be known before the closing of the merger, and will
         increase or decrease as the market price of Broadbase common stock
         increases or decreases. Servicesoft is not permitted to terminate its
         obligations to complete the merger based solely on changes in the value
         of Broadbase common stock.

Q:  WILL SERVICESOFT STOCKHOLDERS RECEIVE ALL OF THEIR BROADBASE SHARES
    IMMEDIATELY FOLLOWING THE MERGER? (PAGE 70)

     A:  An escrow agent will hold 10% of the shares to be issued in the merger
         in an escrow account for a period of one year after the closing of the
         merger. These shares will be held as collateral to satisfy any
         indemnification claims that may be made by Broadbase. Shares that have
         not been used to satisfy indemnification claims will be released to
         former Servicesoft stockholders on the first anniversary of the closing
         of the merger unless indemnification claims made before the first
<PAGE>   9

         anniversary remain unresolved, in which case a portion of the shares
         will be retained until those claims are resolved.

         Servicesoft has appointed Mark S. Skapinker, the current Chairman of
         the Board of Directors of Servicesoft, as the representative of the
         Servicesoft stockholders with respect to the escrow account. Mr.
         Skapinker will be authorized to make decisions and take actions
         regarding the escrow account on the stockholders' behalf.

Q:  WILL THERE BE RESTRICTIONS ON RESELLING BROADBASE SHARES ISSUED IN THE
    MERGER? (PAGE 73)

     A:  All of Servicesoft's stockholders, other than Servicesoft affiliates,
         will generally be permitted to resell the Broadbase common stock they
         receive in the merger in exchange for their Servicesoft stock without
         restriction. Servicesoft affiliates have agreed not to sell any shares
         until 90 days after the merger is completed. In addition, they will
         have to comply with securities laws in reselling shares and will
         generally be subject to other contractual restrictions and Broadbase
         trading policies. Shares that were subject to a right of repurchase by
         Servicesoft before the merger will generally be subject to a right of
         repurchase after the merger.

Q:  WHAT WILL HAPPEN TO SERVICESOFT STOCK OPTIONS AND WARRANTS AS A RESULT OF
    THE MERGER? (PAGE 69)

     A:  Each Servicesoft stock option and warrant will automatically be
         converted into an option or warrant to purchase Broadbase common stock.
         The number of shares subject to each new Broadbase stock option or
         warrant will be equal to 1.4404, multiplied by the number of shares
         subject to the Servicesoft stock option or warrant, rounded down to the
         nearest whole share. The exercise price per share for each new
         Broadbase stock option and warrant will be equal to the exercise price
         per share of the Servicesoft stock option or warrant, divided by
         1.4404, rounded up to the nearest whole cent. The other terms of the
         new Broadbase stock options and warrants will be substantially the same
         as those of the former Servicesoft stock options and warrants. Holders
         of Servicesoft stock options and warrants do not have to take any
         action to receive their Broadbase stock options and warrants.

Q:  WHAT IF I CURRENTLY OWN SHARES OF SERVICESOFT PREFERRED STOCK OR
    EXCHANGEABLE SHARES OF SERVICESOFT CANADA? (PAGE 68)

     A.  It is a condition to the closing of the merger that holders of shares
         of exchangeable common and exchangeable preferred stock of Servicesoft
         Canada exchange those shares for shares of common or preferred stock of
         Servicesoft. In addition, it is a condition to the closing of the
         merger that holders of Servicesoft preferred stock convert those shares
         into Servicesoft common stock before the closing of the merger.
         Servicesoft will separately solicit these stockholders regarding the
         conversion or exchange of their shares. As a result, each share of
         Servicesoft Canada's exchangeable common stock will be exchanged for
         one share of Servicesoft common stock, each share of Servicesoft
         Canada's exchangeable preferred stock will be exchanged for one share
         of Servicesoft Series H preferred stock, and each share of Servicesoft
         preferred stock will be converted into one share of Servicesoft common
         stock.

Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED? (PAGE 82)

     A:  We are working toward completing the merger as quickly as possible. We
         hope to complete the merger during the fourth quarter of 2000. However,
         the merger is subject to several conditions that could affect the
         timing of its completion.

Q:  HOW DO SERVICESOFT'S EXECUTIVE OFFICERS AND DIRECTORS PLAN TO VOTE ON THE
    MERGER? (PAGE 88)

     A:  Servicesoft's board of directors has unanimously approved the merger
         agreement and the merger, and recommends approval by Servicesoft's
         stockholders. Servicesoft's executive officers and

                                        2
<PAGE>   10

directors, together with certain venture capital firms affiliated with some of
these directors and other designated stockholders, have already agreed to vote
in favor of the merger agreement and the merger. These stockholders hold
        approximately      % of the voting power of the Servicesoft common and
        preferred stock entitled to vote on these matters as of the record date,
        and approximately      % of the Servicesoft preferred stock entitled to
        a separate vote on these matters as of the record date. Accordingly,
        these stockholders possess enough votes to approve these matters, even
        if no other stockholder votes in favor of these matters.

Q:  HOW DO BROADBASE'S EXECUTIVE OFFICERS AND DIRECTORS PLAN TO VOTE ON THE
    ISSUANCE OF SHARES OF BROADBASE COMMON STOCK IN THE MERGER? (PAGE 88)

     A:  Broadbase's board of directors has unanimously approved the merger
         agreement, the merger and the issuance of shares of Broadbase common
         stock to Servicesoft stockholders, and recommends that Broadbase's
         stockholders approve the issuance of shares of Broadbase common stock
         in the merger. Broadbase's executive officers and directors, together
         with certain venture capital firms affiliated with some of these
         directors, have already agreed to vote in favor of the issuance of
         shares of Broadbase common stock in the merger. These stockholders hold
         approximately      % of the total shares entitled to vote on these
         matters as of the record date.

Q:  ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE
    MERGER? (PAGE 19)

     A:  Yes. For example, Broadbase might not realize the expected benefits of
         the merger. Also, the value of the Broadbase shares to be issued to
         Servicesoft stockholders in the merger will decrease if the trading
         price of Broadbase common stock decreases before or after the merger.

Q:  WHAT DO I NEED TO DO NOW? (PAGES 35 AND 47)

     A:  We urge you to read this document carefully, including the annexes, and
         to consider how the merger affects you. Then, mail your signed proxy
         card in the enclosed return envelope as soon as possible so that your
         shares may be represented at your stockholders' meeting. If you return
         your signed proxy but do not include instructions on how to vote it,
         your shares will be voted "FOR" the merger-related proposal. If you do
         not return your proxy card or otherwise vote your shares, you will, in
         effect, be voting against the merger.

Q:  WHAT DO I DO IF I WANT TO CHANGE OR REVOKE MY VOTE? (PAGES 36 AND 48)

     A:  If you want to change your vote and you have already submitted your
         proxy, you may attend your stockholders' meeting and vote in person, or
         sign and date another proxy card as of a date later than the proxy you
         submitted originally, and submit this proxy to the secretary of
         Broadbase or Servicesoft, as appropriate. You may also revoke your
         proxy by sending written notice to the secretary of Broadbase or
         Servicesoft, as appropriate, before your meeting.

Q:  IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
    SHARES FOR ME? (PAGE 36)

     A:  No, unless you instruct your broker to do so. We urge you to instruct
         your broker to vote your shares, following the procedure provided by
         your broker.

Q:  IF I AM A SERVICESOFT STOCKHOLDER, SHOULD I SEND IN MY SERVICESOFT STOCK
    CERTIFICATES NOW? (PAGE 70)

     A:  No. After the merger is completed, we will send you written
         instructions for exchanging your Servicesoft stock certificates for
         Broadbase stock certificates.

                                        3
<PAGE>   11

Q:  WHAT ARE THE ANTICIPATED TAX CONSEQUENCES OF THE MERGER? (PAGE 71)

     A:  Broadbase and Servicesoft intend the exchange of Servicesoft common
         stock for Broadbase common stock to be tax-free to Servicesoft
         stockholders for United States federal income tax purposes, except that
         Servicesoft stockholders will recognize gain or loss with respect to
         cash received instead of fractional shares or if they exercise their
         appraisal rights. However, tax matters are complicated, and we urge
         Servicesoft stockholders to consult their own tax advisors to determine
         their particular tax consequences.

Q:  AM I ENTITLED TO DISSENTERS' OR APPRAISAL RIGHTS? (PAGE 71)

     A:  Under Delaware law, holders of Servicesoft stock may exercise appraisal
         rights in the merger. Holders of Broadbase common stock are not
         entitled to dissenters' or appraisal rights in the merger.

Q:  WHOM SHOULD I CALL WITH QUESTIONS?

     A:  Servicesoft stockholders should call Daniel J. Kossmann, Chief
         Financial Officer of Servicesoft, at (508) 653-4000, with any questions
         about the merger. Broadbase stockholders should call Broadbase's
         Investor Relations Department at (650) 614-8300 with any questions
         about the merger.

         You may also obtain additional information about Broadbase and

     Broadbase software integrates information from numerous points of customer
interaction by pulling information from multiple data sources and transforming
it into a standard format that can be analyzed. Broadbase software then analyzes
this reformatted information to provide a comprehensive understanding of the
customer life cycle from initial identification through acquisition and
retention. Broadbase products then allow businesses to translate this analysis
into specific actions such as targeting profitable customers, personalizing
customer interactions and identifying opportunities to sell complementary or
higher-end products and services. In addition, Broadbase's eMA (eMarketing
Automation) application enables businesses to act on this analysis through
automated marketing campaigns over the Internet and traditional channels. By
integrating, analyzing and acting on valuable customer information, Broadbase
products enable businesses to build long-lasting and profitable customer
relationships.

                           SUMMARY OF THE TRANSACTION

THE MERGER

     In the proposed merger, a wholly-owned subsidiary of Broadbase will merge
into Servicesoft, with Servicesoft surviving the merger as a wholly-owned
subsidiary of Broadbase. The merger agreement is attached to this document as
Annex A. We encourage you to read the merger agreement carefully.

THE MERGER CONSIDERATION (PAGE 68)

     Each outstanding share of Servicesoft common stock will be converted into
the right to receive 1.4404 shares of Broadbase common stock upon the completion
of the merger. Servicesoft is required under the merger agreement to cause
holders of its preferred stock to convert their preferred stock into common
stock before the closing of the merger. Servicesoft will separately solicit
these stockholders regarding the conversion of their shares. However, if any
shares of Servicesoft preferred stock remain outstanding at the time of the
merger and Broadbase agrees to waive this condition, the preferred shares will
also be converted into Broadbase common stock at the exchange ratio of 1.4404.
Broadbase will not issue any fractional shares of Broadbase common stock in the
merger. Instead, Servicesoft stockholders will receive cash for any fractional
shares they would otherwise have received.

TREATMENT OF SERVICESOFT'S OPTIONS AND WARRANTS (PAGE 69)

     Each Servicesoft stock option and warrant will automatically be converted
into an option or warrant to purchase Broadbase common stock. The number of
shares subject to each new Broadbase stock option or warrant will be equal to
1.4404, multiplied by the number of shares subject to the Servicesoft stock
option or warrant, rounded down to the nearest whole share. The exercise price
per share for each new Broadbase stock option and warrant will be equal to the
exercise price per share of the Servicesoft stock option or warrant, divided by
1.4404, rounded up to the nearest whole cent.

ESCROW (PAGE 70)

     An escrow agent will hold 10% of the shares to be issued in the merger in
an escrow account for a period of one year after the closing of the merger.
These shares will be held as collateral to satisfy any indemnification claims
made by Broadbase. For additional information, please refer to the section of
this summary entitled "Escrow agreement."

RECOMMENDATIONS OF BROADBASE'S AND SERVICESOFT'S BOARDS OF DIRECTORS

     Broadbase (page 55). Broadbase's board of directors unanimously approved
the issuance of shares of Broadbase common stock in the merger, the amendment to
Broadbase's certificate of incorporation and the amendments to Broadbase's 1999
Equity Incentive Plan and 1999 Employee Stock Purchase Plan, and recommends that
Broadbase's stockholders approve these items.

     Servicesoft (page 58). Servicesoft's board of directors unanimously
approved the merger agreement and the merger, and recommends that Servicesoft's
stockholders approve these items.

REASONS FOR THE MERGER (PAGES 53 AND 55)

     Broadbase and Servicesoft believe the merger will allow them to:

     - combine complementary technologies, products and services into a
       comprehensive, integrated e-customer relationship management suite;

     - strengthen and enhance their competitive market positions by addressing a
       broader range of customer needs;

     - cross-sell products and services, particularly in view of the absence of
       a significant overlap in their customer bases;

     - expand the size and productivity of their sales forces; and

     - combine their engineering, professional service and managerial resources
       to expand and enhance the operations of both companies.

                                        6
<PAGE>   14

     Broadbase and Servicesoft caution you that these benefits may not be
realized. You should carefully consider the discussion of risks relating to the
merger contained in the section entitled "Risk Factors" beginning on page 19.

OPINIONS OF FINANCIAL ADVISORS (PAGES 58 AND 62)

     In deciding to approve the merger, Broadbase's and Servicesoft's boards of
directors considered, among other things, opinions from their respective
financial advisors as to the fairness of the exchange ratio from a financial
point of view. Broadbase received an opinion from its financial advisor, Dain
Rauscher Wessels, and Servicesoft received an opinion from its financial
advisor, Morgan Stanley & Co. Incorporated. The Dain Rauscher opinion letter is
attached as Annex F, and the Morgan Stanley opinion letter is attached as Annex
G. We urge you to read these letters carefully.

     Broadbase retained Morgan Stanley as its financial advisor, and Servicesoft
retained Morgan Stanley to provide it with a fairness opinion, each with the
consent of the other party. Morgan Stanley will receive customary fees for such
services. Broadbase and Servicesoft also consented to the use of separate teams
by Morgan Stanley to represent each company, and to share information regarding
each company. Broadbase was aware before engaging Morgan Stanley that Morgan
Stanley owned a pre-existing 0.55% equity interest in Servicesoft. The decision
to retain Morgan Stanley was based on its reputation, its extensive knowledge of
each company's business and its past relationships with each company. Morgan
Stanley did not participate in the negotiation of the exchange ratio. The
exchange ratio was negotiated through arm's length negotiations between
Broadbase and Servicesoft and was approved by each company's board of directors.

THE STOCKHOLDER MEETINGS

     Broadbase (page 35). Broadbase's board of directors has called a special
meeting of the Broadbase stockholders to vote on the issuance of stock in the
merger, the amendment to Broadbase's certificate of incorporation and amendments
to its employee benefits plans. The meeting is scheduled for                ,
               , 2000 at        , Pacific Time, at the Stanford Park Hotel
located at 100 El Camino Real, Menlo Park, California 94025. Broadbase will
solicit proxies from its stockholders before the meeting.

     Servicesoft (page 47). Servicesoft's board of directors has called a
special meeting of the Servicesoft stockholders to vote on the merger and the
merger agreement. The meeting is scheduled for                ,                ,
2000 at        , Eastern Time, at Servicesoft's executive offices located at Two
Apple Hill Drive, Natick, Massachusetts 01760. Servicesoft will solicit proxies
from its stockholders before the meeting.

VOTES REQUIRED FOR APPROVAL

     Broadbase (page 35). The holders of a majority of the shares of Broadbase
common stock outstanding must approve the proposal to issue shares of Broadbase
common stock in the Servicesoft acquisition and to amend Broadbase's certificate
of incorporation. Directors, executive officers and other affiliated
stockholders of Broadbase who entered into voting agreements in connection with
the merger collectively held approximately      % of the outstanding shares of
Broadbase common stock as of the record date. Each of these stockholders has
agreed to vote in favor of the merger-related proposal.

     Servicesoft (page 47). The holders of a majority of the outstanding shares
of Servicesoft common stock and preferred stock, voting together as a class, and
a majority of the outstanding shares of Servicesoft preferred stock, voting as a
separate class, must approve the merger agreement and the merger. For purposes
of these votes, the holders of exchangeable common stock of Servicesoft Canada,
a subsidiary of Servicesoft, vote with the holders of Servicesoft common stock,
and the holders of exchangeable preferred stock of Servicesoft Canada vote with
the holders of Servicesoft preferred stock. Directors, executive officers and
designated stockholders of Servicesoft who entered into voting agreements in
connection with the merger collectively held approximately      % of the voting
power of the Servicesoft common and preferred stock and approximately      % of
the voting power of the Servicesoft preferred
                                        7
<PAGE>   15

stock entitled to vote on these matters as of the record date. Each of these
stockholders has agreed to vote in favor of the merger agreement and the merger.
These voting agreements also contain agreements to vote against various actions
that could impede the merger, including other mergers or substantial sales of
assets of Servicesoft. Accordingly, stockholders holding enough shares of
Servicesoft stock to approve the merger have already agreed to vote in favor of
the merger.

CONDITIONS TO CLOSING THE MERGER (PAGE 82)

     The obligations of Broadbase and Servicesoft to complete the merger are
contingent upon the satisfaction of several conditions, including the following:

     - Servicesoft's stockholders must have approved the merger agreement and
       the merger;

     - Broadbase's stockholders must have approved the issuance of the shares of
       Broadbase common stock in the merger and the amendment to Broadbase's
       certificate of incorporation;

     - Servicesoft's stockholders must have approved the agreements that could
       reasonably give rise to payment of any compensation that, in the absence
       of such approval, would not be deductible under Section 280G of the
       Internal Revenue Code, or the parties to these agreements must have
       agreed to waive receipt of any such non-deductible amounts;

     - all shares of exchangeable preferred stock and exchangeable common stock
       of Servicesoft Canada must have been exchanged for Servicesoft Series H
       preferred stock or Servicesoft common stock, as applicable, and all
       shares of Servicesoft preferred stock must have been converted into
       shares of Servicesoft common stock;

     - Broadbase's registration statement must be effective, no stop order
       suspending its effectiveness may be in effect and no proceedings for
       suspending its effectiveness may be pending before or threatened by the
       SEC;

     - the applicable waiting periods under antitrust laws must have expired or
       been terminated;

     - the representations and warranties of each party in the merger agreement
       must be true and correct in all material respects;

     - the parties must have complied in all material respects with their
       respective agreements in the merger agreement;

     - no material adverse effect, as defined on page 84 of this document, with
       respect to Broadbase or Servicesoft shall have occurred;

     - all third party consents and approvals that, if not obtained, would have
       a material adverse effect on Servicesoft, must have been obtained by
       Servicesoft;

     - Broadbase must have appointed designated individuals to its board of
       directors; and

     - holders of no more than 10% of Servicesoft common stock shall have
       exercised appraisal rights.

     If either Broadbase or Servicesoft waives any conditions, Broadbase and
Servicesoft will consider the facts and circumstances at that time and make a
joint determination as to whether a resolicitation of proxies from stockholders
is appropriate.

NO OTHER NEGOTIATIONS (PAGE 79)

     Until the merger is completed or the merger agreement is terminated,
Servicesoft has agreed not to solicit or initiate any proposals by third parties
to acquire 15% or more of the voting stock of Servicesoft or 10% or more of the
assets of Servicesoft. However, if Servicesoft receives an unsolicited, written,
bona fide proposal for such an acquisition that its board of directors
reasonably concludes based on written advice of its financial advisor is a
superior offer, as described on page 79 of this document, Servicesoft may
furnish non-public information regarding itself and may enter into discussions
with the person or group who has made the proposal if it provides written notice
to Broadbase and follows other specified procedures. Servicesoft has agreed to
inform Broadbase promptly as to any such proposal, or request for non-public
information or inquiry that it reasonably believes would lead to such a
proposal, and of the status and details of the proposal.
                                        8
<PAGE>   16

     Servicesoft's board of directors may change its recommendation in favor of
the merger, without causing Servicesoft to violate the merger agreement, if it
receives a superior offer and Broadbase does not respond with a corresponding
offer at least as favorable as the superior offer. However, even if
Servicesoft's board of directors changes its recommendation, certain
stockholders of Servicesoft that hold enough shares of Servicesoft stock to
approve the merger have already entered into voting agreements and agreed to
vote in favor of the merger. See the section of this summary entitled "Votes
required for approval."

     Until the merger is completed or the merger agreement is terminated,
Broadbase has agreed not to, directly or indirectly, solicit or initiate the
making, submission or announcement of any acquisition of Broadbase by another
company. Broadbase's board of directors may change its recommendation in favor
of the merger if another company offers to buy Broadbase, and requires as a
condition of the acquisition that the merger with Servicesoft be abandoned,
provided that Broadbase's board of directors follows specified procedures.

TERMINATION OF THE MERGER AGREEMENT (PAGE 84)

     The merger agreement can be terminated and the merger abandoned at any time
prior to the closing of the merger:

     - by the mutual written consent of Broadbase and Servicesoft;

     - by either Broadbase or Servicesoft if the terminating party has not
       materially breached the merger agreement, the other has materially
       breached the merger agreement and the breach is not cured within 15 days
       of written notice of the breach;

     - by either Broadbase or Servicesoft if the merger is not completed by
       February 28, 2001 for any reason, provided that the terminating party has
       not caused the delay through a breach of the merger agreement;

     - by either Broadbase or Servicesoft if there is a final nonappealable
       order of a federal or state court in effect that prevents consummation of
       the merger, or if any statute, rule, regulation or order becomes
       applicable to the merger that would make its consummation illegal; and

     - by either Broadbase or Servicesoft if the required approval of either
       company's stockholders contemplated by the merger agreement has not been
       obtained because of the failure to obtain the required vote, except that
       this right to terminate the agreement will not be available to a party if
       it caused the failure to obtain the approval of its stockholders through
       a breach of the merger agreement.

TERMINATION FEES (PAGE 85)

     If the merger agreement is terminated by either party because of a failure
to obtain the required consent of the other party's stockholders, the breaching
party must, within two days after the date of the termination, pay the
non-breaching party a termination fee of $12.5 million. In addition, if the
merger agreement is terminated by either party because of an uncured material
breach of the agreement by the other party, an acquisition of the breaching
party is publicly announced prior to the termination of the merger agreement and
either the breaching party is acquired or enters into an agreement to be
acquired within nine months of the termination, the breaching party must pay the
non-breaching party the $12.5 million fee within two days of the acquisition of
the breaching party.

     If the merger agreement is terminated by either party because of a failure
to obtain the required consent of Broadbase's stockholders and Broadbase's board
of directors did not recommend the merger to Broadbase's stockholders, then, in
addition to the $12.5 million termination fee, Broadbase will pay Servicesoft
any portion of the $15 million loan amount that has not yet been provided to
Servicesoft and any outstanding principal and accrued interest under this loan
will be forgiven.

VOTING AGREEMENTS (PAGE 88)

     At the time that the merger agreement was signed, executive officers,
directors and designated stockholders of each party entered into a voting
agreement with the other party. The voting agreements require these stockholders
to vote all the shares of voting stock that they own in favor of the merger and
any proposals that must be approved for the merger to occur, and to vote against
competing proposals or proposals in opposition to the merger. The percentage
ownership of these stockholders is summarized in the section of this summary
entitled "Votes required for approval." The voting agreement forms are attached
to this document as Annex C and Annex D. We urge you to read them in their
entirety.

ESCROW AGREEMENT (PAGE 89)

     The escrow agent will hold 10% of the shares to be issued in the merger in
an escrow account for a period of one year following the merger. The escrow
account is similar to a security deposit. Servicesoft has made various
representations and covenants to Broadbase in the merger agreement. If these
representations turn out to be incorrect, or if Servicesoft does not comply with
its covenants, Broadbase may recover its damages out of the escrow account. An
escrow agreement to be signed before the closing of the merger will govern how
Broadbase can recover against the escrow account, how a representative of the
Servicesoft stockholders can dispute Broadbase claims, and the rights and
responsibilities of the escrow agent. The escrow agent will be State Street Bank
and Trust Company of California. The Servicesoft stockholders' representative
will be Mark S. Skapinker, the current Chairman of the Board of Directors of
Servicesoft. The form of the escrow agreement is attached to this document as
Annex E. We urge you to read it in its entirety.

BRIDGE LOANS (PAGE 89)

     Broadbase has agreed to loan Servicesoft up to $15 million during the
pre-closing period. Servicesoft will issue a convertible promissory note in
exchange for each of these loans. The notes will accrue interest at a rate of
8.5% per year and will become due on December 31, 2002. If the merger agreement
is terminated, Broadbase can require Servicesoft to apply up to 50% of the funds
received by Servicesoft in any sales of Servicesoft stock during the one-year
period following the termination towards repayment of the loans, and Servicesoft
must repay any unpaid portion of the loans on the first anniversary of the
termination. In addition, Broadbase can require Servicesoft to repay the loans
in advance of the due date if Servicesoft is acquired during this period.
Broadbase can also elect to convert the loans into shares of Servicesoft stock
if Servicesoft does not repay the loans when due or if the merger agreement is
terminated and Servicesoft sells stock in a fundraising transaction.

EMPLOYMENT AGREEMENTS (PAGE 90)

     At the time the merger agreement was signed, designated employees of
Servicesoft entered into employment agreements with Broadbase. These employment
agreements include non-competition and severance provisions.

ACCOUNTING TREATMENT OF THE MERGER (PAGE 72)

     Broadbase intends to account for the merger as a purchase for financial
accounting purposes under generally accepted accounting principles.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS IN THE MERGER (PAGE 68)

     The executive officers and directors of Broadbase and Servicesoft have
interests in the merger that are different from, or are in addition to, those of
Broadbase and Servicesoft stockholders generally. These interests include the
following:

     - Massood Zarrabian, the Chief Executive Officer and President of
       Servicesoft, and Robert E. Davoli, a director of Servicesoft, will become
       members of Broadbase's board of directors after the merger;

                                       10
<PAGE>   18

     - Mr. Zarrabian, Daniel J. Kossmann, Paul R. Maguire and Alf Saggesse, each
       an executive officer of Servicesoft, have employment agreements with
       Broadbase that provide for benefits upon completion of the merger,
       including severance and other payments and acceleration of restricted
       stock and stock option vesting;

     - Executive officers of Servicesoft may become officers of Broadbase after
       the merger;

     - Many executive officers and directors of Servicesoft hold substantial
       interests, in the form of Servicesoft shares or stock options, that will
       be exchanged for Broadbase shares or options in the merger;

     - Several executive officers and directors of Servicesoft have agreements
       that provide for benefits, including severance and other payments and
       acceleration of stock option vesting, that may be triggered upon the
       closing of the merger or termination of employment after the closing of
       the merger; and

     - Executive officers and directors of both Broadbase and Servicesoft have
       customary rights to indemnification against specified liabilities.

As a result, these executive officers and directors could be more likely to vote
in favor of and to recommend the approval of the merger than if they did not
hold these interests.

CHANGES IN BROADBASE'S BOARD OF DIRECTORS

     In connection with the merger, Massood Zarrabian, the Chief Executive
Officer and President of Servicesoft, and Robert E. Davoli, currently a director
of Servicesoft, will become members of Broadbase's board of directors. Broadbase
expects that the size of its board of directors will remain fixed at five
members after the completion of the merger.

ANTITRUST APPROVAL REQUIRED TO COMPLETE THE MERGER (PAGE 73)

     The merger is subject to antitrust laws. Broadbase, Servicesoft and Sigma
Partners IV, L.P., a Servicesoft stockholder that will acquire a reportable
amount of Broadbase shares as a result of the merger, have made the required
filings with the Department of Justice and the Federal Trade Commission and will
make any necessary filings with foreign regulatory agencies. However, the
Department of Justice or the Federal Trade Commission, as well as a foreign
regulatory agency or government, state or private person, may challenge the
merger at any time before or after its completion.

RESTRICTIONS ON THE ABILITY TO SELL BROADBASE STOCK (PAGE 73)

     All shares of Broadbase common stock received in the merger in exchange for
outstanding shares of Servicesoft stock will be freely transferable, except for
shares held in escrow or subject to lock-up agreements or unless the holder is
considered an affiliate of either Broadbase or Servicesoft under the federal
securities laws.

ADDITIONAL MATTERS TO BE VOTED UPON BY BROADBASE STOCKHOLDERS (PAGES 40 AND 44)

     As part of the proposal to approve the issuance of shares in the
Servicesoft acquisition, Broadbase stockholders will vote on an amendment to
Broadbase's certificate of incorporation to increase the number of authorized
shares of Broadbase common stock from 90,000,000 shares to 350,000,000 shares.
This amendment is a condition to the completion of the merger. Broadbase's
stockholders will also be asked to approve an increase of 4,000,000 shares
reserved for issuance under Broadbase's 1999 Equity Incentive Plan and an
increase of 1,000,000 shares reserved for issuance under Broadbase's 1999
Employee Stock Purchase Plan.

reference contains forward-looking statements within the safe harbor provisions
of the Private Securities Litigation Reform Act. These statements include
statements with respect to Broadbase's and Servicesoft's financial condition,
results of operations and business and on the expected impact of the merger on

       in the merger will increase or decrease prior to completion of the
       merger;

     - the possibility that the merger will not be consummated;

     - the possibility that the anticipated benefits from the merger will not be
       realized;

     - the possibility that costs or difficulties related to the integration of
       our operations, products and technologies will be greater than expected;

     - our dependence on the timely development, introduction and customer
       acceptance of new products and services;

     - the impact of competition on revenues and margins;

     - other risks and uncertainties, including the risks and uncertainties
       involved in continued acceptance of the combined company's products and
       services, the unsettled conditions in the Internet software and other
       high-technology industries and the ability to attract and retain key
       personnel;

     - other risk factors as may be detailed from time to time in Servicesoft's
       public announcements, and Broadbase's public announcements and filings
       with the Securities and Exchange Commission.

     In evaluating the merger, you should carefully consider the discussion of
these and other factors in the section entitled "Risk Factors" beginning on page
19.

COMPARATIVE MARKET PRICE INFORMATION

     The following table sets forth the closing prices per share of Broadbase
common stock on the Nasdaq National Market on September 15, 2000, the last full
trading day prior to the public announcement of the proposed merger, and on
October 25, 2000, the latest practicable trading day before the printing of this
document. The table also sets forth the equivalent per share prices for
Servicesoft common stock on those dates. The equivalent price per share is equal
to the closing price of a share of Broadbase common stock on that date
multiplied by 1.4404, the number of shares of Broadbase common stock to be
issued in exchange for each share of Servicesoft common stock and preferred
stock.

</TABLE>

     The trading price of Broadbase common stock may fluctuate. However, the
exchange ratio will not be adjusted to compensate Servicesoft stockholders for
decreases in the market price of Broadbase common stock that could occur before
the merger is completed. Accordingly, if the market price of Broadbase common
stock decreases before the merger is completed, the value of the Broadbase
common stock to be received in the merger in exchange for Servicesoft common
stock would correspondingly decrease. Servicesoft stockholders are urged to
obtain current market quotations for Broadbase common stock.

                 BROADBASE'S SELECTED HISTORICAL FINANCIAL DATA

     The following selected historical consolidated financial data of Broadbase
has been derived from Broadbase's audited consolidated financial statements and
related notes for the same periods and should be read together with those
financial statements and related notes that are incorporated into this document
by reference.

     The consolidated statement of operations data for the six-month periods
ended June 30, 2000 and June 30, 1999 and the balance sheet data as of June 30,
2000 has been derived from Broadbase's unaudited interim consolidated financial
statements. The unaudited interim financial statements have been prepared on the
same basis as Broadbase's audited financial statements and, in Broadbase's
opinion, include all adjustments, consisting only of normal recurring
adjustments, which Broadbase considers necessary for a fair presentation of its
results of operations and financial position for these periods. There is no
difference between historical basic and diluted net loss per common share since
potential common shares from the conversion of preferred stock and the exercise
of options and warrants are anti-dilutive for all periods presented. Broadbase's
results for the six months ended June 30, 2000 reflect the merger with Rubric,
Inc. which was accounted for using the purchase method of accounting.
Accordingly, the results of operations of Rubric are included in Broadbase's
results from February 1, 2000, the closing date of the merger. Historical
results are not necessarily indicative of future results.

               SERVICESOFT'S SELECTED CONSOLIDATED FINANCIAL DATA

     The following selected consolidated financial data should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations", beginning on page 127 of this document, and
Servicesoft's consolidated financial statements and related notes, beginning on
page F-1 of this document. The statement of operations data for the years ended
December 31, 1997, 1998 and 1999 and the balance sheet data as of December 31,
1998 and 1999 are derived from Servicesoft's audited consolidated financial
statements, which are included in this document. The statement of operations
data for the years ended December 31, 1995 and 1996 and the balance sheet data
as of December 31, 1995, 1996 and 1997 are derived from Servicesoft's audited
consolidated financial statements not included in this document.

     The statement of operations data for the six-month period ended June 30,
2000 and the balance sheet data as of June 30, 2000 are derived from
Servicesoft's unaudited interim consolidated financial statements. The unaudited
interim financial statements have been prepared on the same basis as
Servicesoft's audited financial statements and, in Servicesoft's opinion,
include all adjustments, consisting only of normal recurring adjustments, which
Servicesoft considers necessary for a fair presentation of its results of
operations and financial position for these periods. There is no difference
between historical basic and diluted net loss per common share since potential
common shares from the conversion of preferred stock and the exercise of options
and warrants are anti-dilutive for all periods presented. Historical results are
not necessarily indicative of future results.

     Servicesoft's results for the year ended December 31, 1999 reflect the
February 12, 1999 merger with Balisoft and the December 17, 1999 acquisition of
Internet Business Advantages which were accounted for using the purchase method.
Accordingly, the results of operations of Balisoft and Internet Business
Advantages are included in Servicesoft's results from the applicable closing
dates. Since the merger with Balisoft and the acquisition of Internet Business
Advantages were completed in 1999, the effects of these transactions are
reflected in the balance sheet data as of December 31, 1999.

         SELECTED UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL DATA

     The selected unaudited pro forma combined condensed financial data set
forth below reflect Broadbase's proposed acquisition of Servicesoft, its
recently completed acquisition of Panopticon, Inc. on September 15, 2000, and
its acquisition of Rubric, Inc. on February 1, 2000, and are derived from the
unaudited pro forma combined condensed financial information, which give effect
to each of the transactions as a purchase. This pro forma financial data should
be read in conjunction with the unaudited pro forma combined condensed financial
information and related notes, which are included in this document, the
historical financial statements and related notes of Servicesoft, Balisoft and
Internet Business Advantages that appear elsewhere in this document, and the
historical financial statements and related notes of Broadbase, Rubric and
Panopticon that are incorporated into this document by reference.

     For pro forma purposes, Broadbase's, Servicesoft's, Panopticon's and
Rubric's historical statements of operations for the six months ended June 30,
2000 and for the year ended December 31, 1999 have been combined to give effect
to the acquisitions as if they had occurred on January 1, 1999. The unaudited
pro forma combined condensed balance sheet data assumes that each of these
acquisitions each took place on June 30, 2000. The total estimated purchase cost
of the acquisition of Servicesoft has been allocated on a preliminary basis to
assets and liabilities based on management's best estimates of their fair value
with the excess cost over the net tangible and intangible assets acquired
allocated to goodwill. This allocation is subject to change pending a final
analysis of the total purchase cost and the fair value of the assets acquired
and liabilities assumed. The impact of these changes could be material.

     The unaudited pro forma combined condensed information is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have occurred if the transactions had
been consummated at the times indicated, nor is it necessarily indicative of
future operating results or financial position of Broadbase.

                                  RISK FACTORS

     The merger involves a high degree of risk. Also, by voting in favor of the
merger, Servicesoft's stockholders will be choosing to invest in Broadbase
common stock. An investment in Broadbase common stock involves a high degree of
risk. Both Broadbase's and Servicesoft's stockholders should carefully consider
the following risk factors, in addition to the other information contained or
incorporated by reference in this document, in deciding whether to vote for the
merger. The risks described below are not the only risks Broadbase and
Servicesoft face. Additional risks that we are unaware of or that we currently
believe are immaterial may become important factors that affect our business.
Any of these risks could result in serious harm to our business, operating
results and financial condition. The trading price of Broadbase's common stock
could decline due to any of these risks, and you may lose all or part of your
investment.

     This document contains and incorporates by reference forward-looking
statements within the safe harbor provisions of the Private Securities
Litigation Reform Act. Forward-looking statements are based on current
expectations that involve a number of uncertainties, including those disclosed
in the risk factors below. Actual results could differ materially from those
projected in the forward-looking statements. Please see the section entitled
"Cautionary Note on Forward-Looking Statements" on page 151.

RISKS RELATED TO THE PROPOSED MERGER

SERVICESOFT'S STOCKHOLDERS WILL RECEIVE A FIXED RATIO OF 1.4404 SHARES OF
BROADBASE COMMON STOCK PER SHARE OF SERVICESOFT STOCK, EVEN IF THERE ARE CHANGES
IN THE TRADING PRICE OF BROADBASE COMMON STOCK BEFORE THE MERGER CLOSES.

     The exchange ratio of 1.4404 shares of Broadbase common stock for each
outstanding share of Servicesoft stock is fixed. The exchange ratio will not be
adjusted, regardless of fluctuations in the trading price of Broadbase common
stock. The specific dollar value of Broadbase common stock that Servicesoft
stockholders will receive upon the completion of the merger will depend on the
market value of Broadbase common stock at the time of the merger. The share
price of Broadbase's common stock is subject to price fluctuations in the market
and has experienced significant volatility. We cannot predict the market price
for Broadbase common stock at any time before or after the merger closes. We
encourage you to obtain current market quotations of Broadbase common stock,
which is quoted on the Nasdaq National Market.

BROADBASE'S PROFITABILITY WILL BE DELAYED AND THEREAFTER REDUCED AS A RESULT OF
ACCOUNTING CHARGES RELATING TO THE ACQUISITION OF SERVICESOFT.

     Broadbase will account for the acquisition of Servicesoft using the
purchase method of accounting. Under the purchase method, the purchase price of
Servicesoft will be allocated to the assets acquired and liabilities assumed
from Servicesoft. As a result, based on an approximate purchase price of $652.9
million, Broadbase expects to record a charge to operations upon the completion
of the merger related to acquired in-process research and development of
approximately $13.0 million. Also, Broadbase expects to record approximately
$550.7 million of intangible assets and goodwill from the Servicesoft
acquisition on its balance sheet which will result in annual amortization
expense of approximately $112.3. These charges will delay and thereafter reduce
Broadbase's profitability.

BROADBASE'S PRO FORMA ACCOUNTING FOR THE SERVICESOFT MERGER MAY CHANGE.

     Broadbase has allocated the total estimated purchase price for the
Servicesoft merger on a preliminary basis for pro forma presentation purposes to
assets and liabilities based on Broadbase's best estimates of the fair value of
these assets and liabilities, with the excess costs over the net assets acquired
allocated to goodwill and other intangible assets and in-process research and
development. This allocation is subject to change pending a final analysis of
the fair values of the assets acquired and liabilities assumed. The impact of
these changes could have a material, negative impact on Broadbase's future
results of operations.

                                       19
<PAGE>   27

IF BROADBASE DOES NOT SUCCESSFULLY INTEGRATE THE OPERATIONS AND PERSONNEL OF
SERVICESOFT IN A TIMELY MANNER, THIS WILL DISRUPT THE COMBINED COMPANY'S
BUSINESS AND COULD NEGATIVELY AFFECT ITS OPERATING RESULTS.

     Broadbase's acquisition of Servicesoft involves risks related to the
integration and management of Servicesoft's operations and personnel. The
integration of Broadbase and Servicesoft will be a complex, time consuming and
expensive process and may disrupt the businesses of both companies if not
completed in a timely and efficient manner. After the merger, Broadbase must
operate as a combined organization utilizing common information and
communication systems, operating procedures, financial controls and human
resources practices.

     Broadbase and Servicesoft may encounter substantial difficulties, costs and
delays involved in integrating their operations, including:

     - potential incompatibility of business cultures;

     - perceived adverse changes in business focus;

     - potential conflicts in distribution, marketing or other important
       relationships; and

     - the loss of key employees and diversion of the attention of management
       from other ongoing business concerns.

     Broadbase's headquarters are located in Menlo Park, California, while
Servicesoft's headquarters are located in Natick, Massachusetts. There are
currently no plans to relocate either of these headquarters. Broadbase's
integration of Servicesoft's operations and personnel may be particularly
difficult due to the bi-coastal locations. Failure to complete the integration
successfully could result in the loss of key personnel and customers. Broadbase
and Servicesoft will need to devote significant resources to the integration of
the acquired operations and personnel, and if unsuccessful, the business of the
combined company will suffer. In addition, the attention and effort devoted to
the integration of the two companies will significantly divert management's
attention from other important issues, which could negatively affect the
business and operating results of the combined company.

IF BROADBASE AND SERVICESOFT DO NOT INTEGRATE THEIR PRODUCTS AND TECHNOLOGIES
QUICKLY AND EFFECTIVELY, MANY OF THE POTENTIAL BENEFITS OF THE MERGER MAY NOT BE
REALIZED.

     Broadbase and Servicesoft will need to integrate their product development
operations, technologies and products. This integration may be difficult and
unpredictable because Broadbase's and Servicesoft's products are highly complex
and were developed independently and without regard to this integration.
Successful integration of Servicesoft's product development operations and
product lines with Broadbase's also requires coordination of different
development and engineering teams, as well as sales and marketing efforts and
personnel. This, too, may be difficult and unpredictable because of possible
differences between Broadbase's and Servicesoft's corporate cultures and
organizations, different product and technology decisions and the geographic
distance between their headquarters. In addition, this integration may take
longer than expected, and the companies may be required to expend more resources
on integration than anticipated. The need to expend additional resources on
integration would reduce the resources which would otherwise be spent on
developing each companies' own products and technologies. If the companies
cannot successfully integrate their products and technologies, or if this
integration takes longer than anticipated, the combined company may not be able
to operate efficiently or realize the expected benefits of the merger.

IN ORDER TO ACHIEVE THE ANTICIPATED BENEFITS OF THE MERGER, THE COMBINED COMPANY
WILL NEED TO SUCCESSFULLY DEVELOP AND INTRODUCE ENHANCED AND NEW PRODUCTS.

     The combined company expects to develop and introduce new products, and
enhanced versions of Servicesoft's and Broadbase's current products, that
interoperate as a single platform. In addition to the risks and uncertainties
inherent in the development and introduction of new products, the need to
develop

                                       20
<PAGE>   28

and introduce, in a timely manner, new products and versions that work
effectively together and allow customers to achieve the benefits of a broader
product offering presents significant additional obstacles. In particular,
because our market is characterized by rapidly shifting customer requirements,
we may not be able to assess these requirements accurately, or our joint
products may not sufficiently satisfy these requirements. In addition, the
introduction of these anticipated new products and versions may result in longer
sales cycles and product implementations, which may cause revenue and operating
income to fluctuate and fail to meet expectations.

     To date, the companies have not thoroughly investigated the obstacles,
technological, market-driven or otherwise, to developing and marketing these new
products and services in a timely and efficient way. The combined company may
not be able to overcome these obstacles, or market acceptance of new products
and services developed by the combined company after the merger may not meet
expectations.

PARTNERS AND CUSTOMERS OF BOTH COMPANIES MAY REACT UNFAVORABLY TO THE MERGER.

     Both Broadbase and Servicesoft have entered into relationships with other
technology companies, including software and services firms, to deliver their
products to customers. Some of these other companies may feel that the combined
company poses new competitive threats to their businesses and as a result may
terminate their relationships with Broadbase or Servicesoft, or reduce their
level of activity on behalf of the combined company. In addition, Broadbase will
need to educate its indirect sales channels regarding Servicesoft's products and
services, and these indirect channels may not market these products and services
effectively or at all.

     The merger may also have the effect of disrupting customer relationships.
Broadbase and Servicesoft customers may not continue their current buying
patterns during the pendency of, and following, the merger. Customers may defer
purchasing decisions as they evaluate the likelihood of successful integration
of Broadbase's and Servicesoft's products and services and the combined
company's future product and service strategy. Also, because of the broader
product and service offering that Broadbase will offer after the merger, some
customers of Broadbase or Servicesoft may view the combined company as more of a
direct competitor than either Broadbase or Servicesoft as an independent
company, and may therefore cancel or fail to place additional orders after the
merger. Any significant delay or reduction in orders for Broadbase's or
Servicesoft's products could have a material, negative impact on the combined
company's operating results after the merger.

IF BROADBASE AND SERVICESOFT ARE NOT BE ABLE TO SUCCESSFULLY CROSS-SELL PRODUCTS
AND SERVICES OF EACH COMPANY TO CUSTOMERS OF THE OTHER, THIS MAY NEGATIVELY
AFFECT THE COMBINED COMPANY'S OPERATING RESULTS.

     After the merger, the combined company intends to offer Broadbase's current
products to existing Servicesoft customers, and Servicesoft's current products
to existing Broadbase customers. There can be no assurance that either company's
customers will have an interest in the other company's products and services.
The failure of cross-marketing efforts would diminish the ability of the
companies to achieve one of the benefits that they expect to realize in the
merger, and could have a material, negative impact on the combined company's
business, financial condition and operating results.

FAILURE TO RETAIN KEY EMPLOYEES COULD DIMINISH THE ANTICIPATED BENEFITS OF THE
MERGER.

     The successful combination of Broadbase and Servicesoft will depend in part
on the retention of personnel critical to the business and operations of the
combined company due to, for example, their technical skills or management
expertise. Employees may experience uncertainty about their future role with
Broadbase until Broadbase's strategies with regards to Servicesoft's employees
are announced or executed. Broadbase and Servicesoft have different corporate
cultures, and Servicesoft employees may not want to work for a larger,
publicly-traded company instead of a smaller, start-up company. Some officers,
including the Chief Executive Officer and President, and all directors of
Servicesoft have agreements that provide for benefits, including severance and
other payments and acceleration of vesting of stock options or restricted stock
grants, that may be triggered upon the closing of the merger, and this may
affect

                                       21
<PAGE>   29

Broadbase's ability to retain these employees. In addition, competitors may
recruit employees before the merger and during integration, as is common in high
technology mergers. If the combined company is unable to retain personnel that
are critical to the successful integration of Servicesoft with Broadbase, it
could face disruptions to its operations, loss of key information, expertise or
know-how and unanticipated additional recruitment and training costs. In
addition, the loss of key personnel could diminish the anticipated benefits of
the merger.

FAILURE TO COMPLETE THE MERGER COULD HARM BROADBASE'S STOCK PRICE AND EACH
COMPANY'S FUTURE BUSINESS AND OPERATIONS.

     The merger is subject to several closing conditions, including approval by
Servicesoft's and Broadbase's stockholders and regulatory agencies, and we
cannot assure you that the merger will be successfully completed. In the event
that the merger is not successfully completed, Servicesoft and Broadbase may be
subject to a number of material risks, including the following:

     - either party may be required to pay the other a termination fee of $12.5
       million;

     - Servicesoft may be required to repay loans of up to $15 million that may
       be borrowed from Broadbase during the interim period;

     - Broadbase may be required to forgive any portion of the loans that are
       outstanding, and to pay any portion of the loans that are not funded to
       Servicesoft;

     - the trading price of Broadbase common stock may decline to the extent
       that the current market price reflects a market assumption that the
       merger will be completed; and

     - costs related to the proposed merger, such as legal, accounting and
       financial advisory fees and employee retention bonuses, must be paid by
       each of the parties, whether or not the merger is completed.

     The announcement of the proposed merger may have a negative impact on
either company's ability to sell its services and products, attract and retain
employees and clients, and maintain strategic relationships with third parties
in the future. If the merger is not completed, either company may not be able to
restore the status of its business as it existed prior to the announcement of
the merger. Furthermore, if the merger is not completed and Servicesoft's board
of directors determines to seek another merger or business combination, it may
not be able to find a partner willing to pay an equivalent or more attractive
price than that which would have been paid in the merger with Broadbase. If the
merger is not completed and Broadbase's board of directors determines to seek
another merger or business combination, it may not be able to find a partner
with comparable technology, products or business.

RISKS RELATED TO THE BUSINESS OF THE COMBINED COMPANY

     Unless otherwise stated, the terms "we" and "our" in this section refer to
the combined company after the merger.

BROADBASE AND SERVICESOFT HAVE INCURRED LOSSES SINCE INCEPTION, AND WE EXPECT
THE COMBINED COMPANY TO INCUR LOSSES FOR THE FORESEEABLE FUTURE.

     Both Broadbase and Servicesoft incurred net losses and losses from
operations for each period from inception through the first six months of 2000.
As of June 30, 2000, Broadbase had accumulated net losses of approximately
$109.8 million, and Servicesoft had accumulated net losses of approximately
$89.8 million. Neither company has achieved profitability to date, and we expect
the combined company to continue to incur substantial losses for the foreseeable
future. We expect to incur increasing sales and marketing, research and
development and general and administrative expenses. As a result, we will need
to significantly increase our revenue to achieve profitability. Although each
company's revenues grew significantly in 1999 and during the first six months of
2000, our growth may not continue at the current

                                       22
<PAGE>   30

rate or at all. Even if we do achieve profitability, we may not be able to
sustain or increase profitability on a quarterly or annual basis in the future.

OUR BUSINESS IS DIFFICULT TO EVALUATE BECAUSE OUR OPERATING HISTORY IS LIMITED.

     The merger will combine two companies that have limited operating histories
in the e-business software industry. Broadbase was incorporated in 1995 and only
recently released several of its current software applications. Although
Servicesoft was formed in 1987, Servicesoft has operated as a developer of
e-service software only since 1996. Because each of the companies is still in
the early stages of its development, we will be subject to the risks, expenses
and uncertainties frequently encountered by young companies. For example,
because Broadbase introduced a number of its products in May 1999, and
Servicesoft just recently introduced its 2001 suite of products, it is difficult
to predict whether our products will continue to be accepted by the market and
the level of revenues we can expect to derive from sales of our products.
Furthermore, several members of our management team have been with us for only a
short period of time. Our revenue and income potential is unproven and depends
on emerging, rapidly changing markets and on acceptance of products that we have
only recently introduced. Because of our limited operating histories and
evolving product offerings, we have limited insights into trends that may emerge
and affect our business.

WE EXPECT OUR QUARTERLY REVENUES AND OPERATING RESULTS TO FLUCTUATE.

     Our revenues and operating results are likely to vary significantly from
quarter to quarter. The factors that affect our quarterly operating results
include:

     - the demand for our products, particularly our e-business applications;

     - the size and timing of customer orders for our products and our
       professional services;

     - uncertainty regarding the timing of the implementation cycle for
       Servicesoft products;

     - increased expenses for sales and marketing, product development and
       administration;

     - changes in the level of sales of professional services as compared to
       product licenses;

     - the timing of new product and service introductions by us or our
       competitors, which could affect the demand for our existing products and
       services;

     - changes in our pricing policies, or changes in the pricing policies of
       our competitors;

     - the purchasing and budgeting cycles of our customers, which could result
       in seasonality;

     - costs incurred with respect to acquisitions of technology or businesses;

     - changes in the mix of our domestic and international sales; and

     - changes in general economic and market conditions.

     Broadbase's quarterly revenues increased 406% from the second quarter of
1999 to the second quarter of 2000, and Servicesoft's quarterly revenues
increased 405% during this same period. We do not believe that this rate of
growth is indicative of the growth in revenues, if any, that we can expect in
the future. Accordingly, we believe that period-to-period comparisons of our
operating results may not be meaningful and you should not rely on these
comparisons as an indication of our future performance. Our operating results
may fall below the expectations of investors. In this event, the market price of
Broadbase common stock would likely decrease.

THE UNPREDICTABLE TIMING OF OUR SALES AND IMPLEMENTATION CYCLE MAKES IT
DIFFICULT TO FORECAST OUR OPERATING RESULTS.

     Our products can have a long and unpredictable sales cycle. Potential
customers often require time to weigh the costs and benefits of our products
compared to those of in-house development and integration

                                       23
<PAGE>   31

efforts. As a result, the companies' sales cycles have typically ranged from
approximately two to seven months, although it can take longer. Consequently, we
face difficulty predicting the quarter in which sales to expected customers will
occur. This contributes to the uncertainty of our future operating results.

     Delays and uncertainty in product and service implementation can compound
the difficulty of forecasting our operating results. In most customer sales,
Broadbase and Servicesoft are involved in the installation of their software
products at the customer site, and each company recognizes revenue from a
customer sale based in part on when the installation is complete. However, the
timing of the commencement and completion of the installation process is subject
to factors that may be beyond either company's control, as this process requires
access to the customer's facilities and coordination with the customer's
personnel after delivery of the software. In addition, customers may elect to
delay product implementations. These factors make it difficult to forecast
operating results and can result in significant variability in period-to-period
results.

OUR OPERATING EXPENSES ARE INCREASING AND CANNOT BE REDUCED QUICKLY IF WE FAIL
TO ACHIEVE EXPECTED REVENUES.

     We plan to significantly increase our operating expenses as we expand our
sales, marketing, research and development, professional services, customer
support and administrative groups. These expenses will be incurred before we
generate any revenues from our increased spending. If we do not significantly
increase revenues as a result of these efforts, we will not achieve
profitability. Our operating expenses are based on our expectations of future
revenues and are relatively fixed in the short term. As a result, we would not
be able to reduce spending quickly if our revenue was lower than we had
projected. Our ability to accurately forecast our quarterly revenue is limited
because of our limited operating history, the rapidly evolving nature of our
market and the sales cycle for our products, which can be long and
unpredictable. If our revenue falls below our expectations in any quarter, or if
we increase our spending ahead of our revenue growth, our operating results will
be lower than expected.

IF WE ACQUIRE ADDITIONAL COMPANIES, PRODUCTS OR TECHNOLOGIES, WE MAY FACE RISKS
SIMILAR TO THOSE THAT WE CURRENTLY FACE IN CONNECTION WITH OUR ACQUISITION OF
SERVICESOFT.

     Broadbase recently acquired Panopticon, Inc., has agreed to acquire
Servicesoft and Decisionism, Inc., and if it is presented with appropriate
opportunities, it may acquire additional companies or make investments in other
companies, products or technologies in the future. We may not realize the
anticipated benefits of any other acquisition or investment. If we acquire
another company, we will likely face the same risks, uncertainties and
disruptions as discussed above with respect to Broadbase's proposed acquisition
of Servicesoft. For example, we may not be able to successfully assimilate the
additional personnel, operations, acquired technology and products into our
business. In particular, we will need to assimilate and retain key professional
services, engineering and marketing personnel. The integration of the operating
personnel, products and technologies of acquired companies into our own will be
a complex, time consuming and expensive process and may disrupt our business if
not completed efficiently or in a timely manner. Furthermore, we may have to
incur debt or issue equity securities to pay for any additional future
acquisitions or investments, the issuance of which could be dilutive to our
existing stockholders.

ACCOUNTING CHARGES RELATING TO CURRENT AND FUTURE ACQUISITIONS WILL PREVENT US
FROM ACHIEVING POSITIVE NET INCOME UNDER GAAP AS QUICKLY AS WE MIGHT OTHERWISE.

     Broadbase has acquired several companies recently in addition to its
proposed acquisition of Servicesoft, and has accounted for these acquisitions
using the purchase method of accounting. Under the purchase method, the purchase
price of the acquired company is allocated based on an independent valuation, to
the specific tangible and intangible assets acquired and liabilities assumed.
Broadbase expects to incur merger related costs in the third quarter of 2000 as
it completes product implementations in connection with its acquisition of
Rubric in February 2000. Also, Broadbase recorded approximately $362.0 million
of intangible assets and goodwill on its balance sheet which will result in
amortization expense of $66.9 million for 2000, $72.7 million for 2001, $72.7
million for 2002, $72.1 million for 2003, $71.6 million
                                       24
<PAGE>   32

for 2004 and $6.0 million for 2005. Broadbase also recorded $28.8 million in
intangible assets and goodwill in connection with its acquisition of Aperio, and
will record approximately $88 million in intangible assets and goodwill in
connection with its acquisition of Panopticon. We will likely record additional
intangible assets and goodwill and merger related costs in connection with
potential future acquisitions. These charges will reduce our net income reported
under GAAP.

WE NEED TO ATTRACT, TRAIN AND RETAIN ADDITIONAL QUALIFIED PERSONNEL IN A
COMPETITIVE EMPLOYMENT MARKET.

     Our success depends on our ability to attract, train and retain qualified,
experienced employees. There is substantial competition for experienced
management, engineering, sales and marketing personnel, particularly in the
market segment in which we compete. If we are unable to retain our existing key
personnel, or to attract, train and retain additional qualified personnel, we
may experience inadequate levels of staffing to develop and sell our products
and perform services for our customers.

     The market price of Broadbase common stock has fluctuated substantially
since Broadbase's initial public offering in September 1999. We have relied
historically on our ability to attract employees using equity incentives, and
any perception by potential and existing employees that our equity incentives
are less attractive could harm our ability to attract and retain qualified
employees.

     We believe that our success will depend on the continued services of our
executive officers. These employees serve "at-will" and may elect to pursue
other opportunities at any time. The loss of any of our executive officers could
harm our business. Several of our executive officers joined us only recently and
have had a limited time to work together. For example, five of Broadbase's
executive officers have joined us during 2000. We cannot assure you that our new
executive officers will be able to work effectively together to manage our
growth and continuing operations.

OUR GROWTH DEPENDS ON MARKET ACCEPTANCE OF OUR APPLICATIONS DESIGNED FOR
INTERNET-BASED SYSTEMS.

     Broadbase first introduced applications designed for Internet-based systems
in May 1999. Servicesoft first introduced its 2000 suite of products in the
fourth quarter of 1999, and only released its 2001 suite of products, on which
it intends to rely for an increasing amount of software license revenue, in the
third quarter of 2000. We expect that our future growth will depend
significantly on revenue from licenses of these applications and related
services. There are significant risks inherent in introducing these new
products. Market acceptance of these new products will depend on the growth of
the market for e-business solutions. This growth may not occur. We cannot assure
you that our new e-business applications will meet customer performance
expectations. If they do not meet customer expectations or the market for these
products fails to develop or develops more slowly than we expect, our business
would be harmed.

OUR BUSINESS WILL SUFFER IF WE DO NOT INCREASE MARKET AWARENESS OF OUR PRODUCTS
BY SIGNIFICANTLY EXPANDING OUR SALES CAPABILITIES.

     We sell our products primarily through our direct sales force. We must
significantly expand our direct sales operations to increase market awareness of
our products and increase revenue. We cannot be certain that we will be
successful in these efforts. Our products and services require sophisticated
sales efforts. As a result, our ability to increase our direct sales operation
will depend on our ability to recruit, train and retain top sales people with
advanced sales skills and technical knowledge. There is a shortage of sales
personnel with these qualifications, and competition for qualified personnel is
intense in our industry. If we are unable to hire or retain qualified sales
personnel, or if newly hired personnel fail to develop the necessary skills or
reach productivity more slowly than anticipated, our business could be harmed.
If we are unable to expand our sales and marketing organizations in a timely
manner, our growth could be limited.

                                       25
<PAGE>   33

WE ARE DEPENDENT ON MARKETING, TECHNOLOGY AND DISTRIBUTION RELATIONSHIPS THAT
MAY GENERALLY BE TERMINATED AT ANY TIME, AND IF OUR CURRENT AND FUTURE
RELATIONSHIPS ARE NOT SUCCESSFUL, OUR GROWTH MAY BE LIMITED.

     We rely on marketing and technology relationships with a variety of
companies which, in part, generate leads for the sale of our products. These
marketing and technology relationships include relationships with:

     - system integrators and consulting firms;

     - vendors of e-commerce and Internet software;

     - vendors of software designed for customer relationship management or for
       management of organizations' operational information;

     - vendors of key technology and platforms;

     - demographic data providers; and

     - an application service provider and an Internet hoster.

If we cannot maintain successful marketing and technology relationships or
cannot enter into additional marketing and technology relationships, we may have
difficulty expanding the sales of our products and our growth may be limited.
While these companies do not sell or distribute our products, we believe that
many of our direct sales are the result of leads generated by vendors of
e-business and enterprise applications that work with our products. Our
marketing and technology relationships are generally not documented in writing,
or are governed by agreements that can be terminated by either party with little
or no prior notice. In addition, companies with which we have marketing,
technology or distribution relationships may promote products of several
different companies. If these companies choose not to promote our products or if
they develop, market or recommend software applications that compete with our
products, our business will be harmed.

     Broadbase and Servicesoft also currently have distribution relationships
with companies located around the world that distribute or resell our products.
Sales through these indirect sales channels accounted for approximately 28.7% of
Broadbase's total revenues for 1998, 35.3% for 1999 and 12.7% for the first six
months of 2000. If we cannot maintain successful relationships with our indirect
sales channel partners, we may have difficulty expanding the sales of our
products and our international growth may be limited.

     In addition, Servicesoft sometimes relies on distributors, value-added
resellers, systems integrators, consultants and other third-party resellers to
recommend Servicesoft products and to install and support these products. If
these companies fail to implement Servicesoft products successfully for their
customers, we may be unable to complete implementation on the schedule required
by the customers. We may not be able to maintain these relationships and enter
into additional relationships that will provide timely and cost-effective
customer support and service.

WE MAY BE UNABLE TO ATTRACT NEW CUSTOMERS IF WE DO NOT DEVELOP NEW PRODUCTS AND
ENHANCEMENTS.

     If we do not continue to improve our products and develop new products that
keep pace with competitive product introductions and technological developments,
satisfy diverse and rapidly evolving customer requirements and achieve market
acceptance, we may be unable to attract new customers. For example, Broadbase
has recently released new versions of a number of our existing analytic
applications. In addition, Servicesoft recently released the Servicesoft 2001
family of software e-service products. We may not be successful in marketing and
supporting these new versions, or developing and marketing other product
enhancements and new products that respond to technological advances and market
changes, on a timely or cost-effective basis. In addition, even if these
products are developed and released, they may not achieve market acceptance. We
have in the past experienced delays in releasing new products and product
enhancements and may experience similar delays in the future. These delays or
problems in the installation or implementation of our new releases may cause
customers to forego purchases of our products.

WE DEPEND ON INCREASED BUSINESS FROM OUR NEW CLIENTS, AND IF WE FAIL TO GROW OUR
CLIENT BASE OR GENERATE REPEAT BUSINESS, OUR OPERATING RESULTS COULD BE HARMED.

     If we fail to grow our client base or generate repeat and expanded business
from our current and future clients, our business and operating results will be
seriously harmed. Some of our clients initially make a limited purchase of our
products and services for pilot programs. These clients may not choose to
purchase additional licenses to expand their use of our products. These clients
have not yet developed or deployed initial applications based on our products.
If these clients do not successfully develop and deploy these initial
applications, they may choose not to purchase deployment licenses or additional
development licenses. The effectiveness of software solutions depends in part on
the widespread adoption and use of our products by customer-support personnel.
Some of our clients who have made initial purchases of our software have
deferred or suspended implementation of our products due to slower than expected
rates of internal adoption by customer support personnel. If more clients decide
to defer or suspend implementation of our products in the future, we will be
unable to increase our revenue from these clients from additional licenses or
maintenance agreements, and our financial position will be seriously harmed. Our
business model depends on the expanded use of our products within our clients'
organizations.

     In addition, as we introduce new versions of our products or new products,
our current clients may not require the functionality of our new products and
may not ultimately license these products. Because the total amount of
maintenance and support fees we receive in any period depends in large part on
the size and number of licenses that we have previously sold, any downturn in
our software license revenue would negatively affect our future services
revenue. In addition, if clients elect not to renew their maintenance
agreements, our services revenue could decline significantly.

MARKET ACCEPTANCE OF OUR PRODUCTS MAY SUFFER IF WE ARE UNABLE TO KEEP PACE WITH
RAPID TECHNOLOGICAL CHANGES AND INDUSTRY STANDARDS.

     Rapidly changing technology and operating system standards, changes in
customer requirements and evolving industry standards may impede market
acceptance of our products. Our new applications have been designed based upon
currently prevailing Internet technology. If new Internet technologies emerge
that are incompatible with our applications, or if competing products emerge
which are based on new technologies or new industry standards which perform
better or cost less than our products, our key products may become obsolete and
our existing and potential customers may seek alternatives to our products. We
may not be able to quickly adapt our products to any new Internet technology,
customer requirements or industry standards.

     Broadbase and Servicesoft have designed their products to work with
databases such as Oracle and Microsoft SQL Server. Any changes to those
databases, or increasing popularity of other databases, could require us to
modify our products, and could cause us to delay releasing future products and
enhancements. Furthermore, software adapters are necessary to integrate our
products with other systems and data sources used by our customers. We must
develop and update these adapters to reflect changes to these systems and data
sources in order to maintain the functionality provided by our products. As a
result, uncertainties related to the timing and nature of new product
announcements, introductions or modifications by vendors of operating systems,
databases, customer relationship management software, web servers and other
enterprise and Internet-based applications could delay our product development,
increase our product development expense or cause customers to delay evaluation,
purchase and deployment of our products.

OUR BUSINESS DEPENDS ON THE ACCEPTANCE AND USE OF THE WINDOWS NT OPERATING
SYSTEM.

     Broadbase's analytic software products and Servicesoft's e-service software
products currently run only on the Windows NT operating system. Any change to
this operating system could require us to modify our products and could cause us
to delay product releases. Any decline in the market acceptance of the Windows
NT operating system for any reason, including as a result of errors or delayed
introduction of enhancement or upgrades, could seriously harm our business. If
potential customers do not want to use the

                                       27
<PAGE>   35

Windows NT operating system, we will need to develop products that run on other
operating systems such as UNIX. The development of new products in response to
these risks would require us to commit a substantial investment of resources,
and we may not be able to successfully develop or introduce such products on a
timely or cost-effective basis, or at all, which could lead potential customers
to choose alternative products.

FAILURE TO LICENSE NECESSARY THIRD PARTY SOFTWARE INCORPORATED IN OUR PRODUCTS
MAY CAUSE DELAYS OR REDUCTIONS IN OUR SALES.

     We license third party software that we incorporate into our products.
These licenses may not continue to be available on commercially reasonable terms
or at all. Some of this technology would be difficult to replace. The loss of
any such license could result in delays or reductions of our applications until
equivalent software is identified, licensed and integrated or developed by us.
If we are required to enter into license agreements with third parties for
replacement technology, we could be subject to higher royalty payments and a
loss of product differentiation.

WE FACE INTENSE COMPETITION THAT COULD MAKE IT DIFFICULT TO ACQUIRE AND RETAIN
CUSTOMERS.

     Our market is intensely competitive, and we expect competition to intensify
in the future. Competitive pressures may make it difficult for us to acquire and
retain customers and may require us to reduce the price of our products. Our
failure to maintain and enhance our competitive position could seriously harm
our business. Our customers' requirements and the technology available to
satisfy those requirements are continually changing. Therefore, we must be able
to respond to these changes in order to remain competitive. Our competitors vary
in size and in the scope and breadth of products and services offered.

     Broadbase currently faces competition from providers of consulting-based
analysis solutions, vendors of point technologies that provide website analysis
and in-house development efforts by potential customers. Servicesoft currently
faces competition from providers of similar e-service software products, and may
compete with companies providing customer relationship management, e-commerce
and communications solutions. In addition, both of us face potential competition
from vendors of other enterprise applications as they expand the functionality
of their product offerings, including companies that design software for
decision support, management of customer relationships or of organizations'
operational information, as well as vendors of database applications.
Accordingly, it is possible that new competitors may emerge and acquire our
market share.

     Some of our current and potential competitors have longer operating
histories and significantly greater financial, technical, marketing and other
resources than we do, and thus may be able to respond more quickly to new or
changing opportunities, technologies and customer requirements. Also, many
current and potential competitors have wider name recognition and more extensive
customer bases that they could leverage, thereby gaining market share to our
detriment. They may be able to undertake more extensive promotional activities,
adopt more aggressive pricing strategies, and offer purchasers more attractive
terms than we can. Our competitors may develop products that are superior to
ours or that achieve greater market acceptance. In addition, we expect that
competition may increase as a result of software industry consolidations and
formations of alliances among industry participants or with third parties. For
example, Kana Communications, Inc. recently acquired Silknet Software, Inc.,
eGain Communications Corp. recently acquired Inference Corporation, Siebel
Systems Inc. recently acquired Onlink Technologies, Inc. and E.piphany, Inc.
recently acquired Octane Software, Inc.

WE DEPEND ON OUR INTELLECTUAL PROPERTY, AND LITIGATION REGARDING OUR
INTELLECTUAL PROPERTY COULD HARM OUR BUSINESS.

     The success of our business is largely dependent on our ability to protect
our intellectual property. Our intellectual property includes our proprietary
technology, trade secrets, trademarks and copyrights in our software products.
We have no patents, although patents may become increasingly important in
software and e-business applications. Unauthorized use or misappropriation of
our intellectual property

                                       28
<PAGE>   36

could seriously harm our business. Copyrights and trademarks discourage
unauthorized use of our software and company and product names and provide us
with a way to enforce our rights in the event that this unauthorized use occurs.
Trade secret laws protect the confidentiality of our propriety technology and
other business information. However, existing copyright, trademark and trade
secret laws afford only limited protection, and the laws of some foreign
countries do not protect our proprietary rights to the same extent as do the
laws of the United States. Third parties may infringe upon our intellectual
property rights, and we may be unable to detect this unauthorized use or
effectively enforce our rights. In addition, any legal action that we may bring
to protect our intellectual property rights could be expensive and distract
management from day-to-day operations.

     Our business activities may infringe upon the proprietary rights of others,
and other parties may assert infringement claims against us. If we become liable
to any other third party for infringing their intellectual property rights, we
could be required to pay substantial damage awards and to develop non-infringing
technology, obtain licenses or cease selling the applications that contain the
infringing intellectual property. We could have to redesign our products, which
could be costly and time-consuming and could substantially delay product
shipments, assuming that a redesign is even feasible. We may be unable to
develop non-infringing technology or obtain licenses on commercially reasonable
terms, if at all. Litigation is subject to inherent uncertainties and any of
these results in connection with a lawsuit could seriously harm our business.
Furthermore, we could incur substantial costs in defending against any
intellectual property litigation, and these costs could increase significantly
if any dispute were to go to trial. Our defense of any litigation, regardless of
the merits of the complaint, will likely be time-consuming, costly and a
distraction for our management personnel. Publicity related to any intellectual
property litigation could also harm the sale of our products and disrupt our
relationships with existing clients.

SOFTWARE DEFECTS COULD LEAD TO LOSS OF REVENUE OR DELAY IN MARKET ACCEPTANCE FOR
OUR PRODUCTS.

     Our software products are internally complex and may contain defects,
especially when they are first introduced or when new versions are released. In
the past, we have discovered software errors in some of our products after their
introduction. Broadbase recently released new versions of a number of its
existing analytic software applications, and Servicesoft recently released the
Servicesoft 2001 family of products. As a result, these products may be
particularly susceptible to errors. Although we continue to evaluate our
products for errors following the commencement of commercial shipments and
receive information from customers regarding errors they detect, if we are not
able to detect and correct errors in products or releases before commencing
commercial shipments, we may experience loss of or delay in revenues, loss of
market share or failure to achieve market acceptance for our products, diversion
of development resources or injury to our reputation.

     We may encounter product liability claims in the future as a result of any
product defects. Our license agreements with our customers typically contain
provisions designed to limit our exposure to potential product liability claims.
However, all domestic and international jurisdictions may not enforce these
limitations. Product liability claims brought against us could divert the
attention of management and key personnel, could be expensive to defend and may
result in adverse settlements and judgments.

BARRIERS TO INTERNATIONAL EXPANSION COULD LIMIT OUR FUTURE GROWTH.

     We have only a limited history of marketing, selling and supporting our
products and services internationally. We conduct our international sales
primarily through direct sales offices in Europe and Asia, through Servicesoft's
subsidiary in Canada and through distributors in Japan. International sales
represented approximately 5.1% of Broadbase's total revenue for the year ended
December 31, 1998, 23.2% for 1999 and 28.2% for the first six months of 2000,
substantially all of which consisted of sales to customers in Canada, Europe and
Japan. International sales represented approximately 10.1% of Servicesoft's
total revenue for the year ended December 31, 1998, 24.9% for the year ended
1999 and 9.9% for the first six months of 2000. We intend to expand our
international operations, but we may face significant barriers to this
expansion. Our failure to manage our international operations effectively could

                                       29
<PAGE>   37

limit the future growth of our business. The expansion of our existing
international operations and entry into additional international markets will
require significant management attention and financial resources.

     Our products must be localized, or customized to meet local user needs, in
order to be sold in particular foreign countries. Developing local versions of
our products for foreign markets is difficult and can take longer than we
anticipate. We currently have limited experience in localizing products and in
testing whether these localized products will be accepted in the targeted
countries. For example, we are currently marketing localized products only in
Germany and Japan. We cannot assure you that our localization efforts will be
successful.

     We also face certain other risks inherent in conducting business
internationally, such as:

     - difficulties and costs of staffing and managing international operations;

     - difficulties in recruiting and training an international staff;

     - difficulties in entering into strategic relationships with companies in
       international markets, particularly in Japan where all of our sales have
       been made through distributors;

     - language and cultural differences;

     - difficulties in collecting accounts receivable and longer collection
       periods;

     - seasonal business activity in certain parts of the world;

     - fluctuations in currency exchange rates;

     - legal and governmental regulatory requirements;

     - tariffs, duties, price controls and other trade barriers; and

     - potentially adverse tax consequences.

Any of these factors could seriously harm our international operations and,
consequently, our business.

     To date, a majority of our international revenue and costs have been
denominated in foreign currencies. We have not engaged in any foreign exchange
hedging transactions to mitigate exchange rate risk. Accordingly, our results of
operations could be harmed by foreign currency exchange rate fluctuations.

WE ARE GROWING RAPIDLY, AND THE FAILURE TO MANAGE OUR GROWTH, INCLUDING
EXPANSION OF OUR MANAGEMENT SYSTEMS, COULD HARM OUR BUSINESS.

     We have grown rapidly and will need to continue to grow in all areas of
operation in order to execute our business strategy. Broadbase's total number of
full-time employees grew from 131 at December 31, 1999 to 320 at September 30,
2000. Servicesoft's total number of full-time employees grew from 243 at
December 31, 1999 to 312 at September 30, 2000. We anticipate further
significant increases in the number of our employees. Our growth has placed
significant demands on management as well as on our administrative, operational
and financial resources and controls. We expect our future growth to cause
similar, and perhaps increased, strain on our systems and controls. If we cannot
effectively establish and improve our processes, we may not be able to manage
our growth successfully or sustain and manage the growth rates we have
experienced in the past.

OUR PROSPECTS FOR OBTAINING ADDITIONAL FINANCING, IF REQUIRED, ARE UNCERTAIN AND
FAILURE TO OBTAIN NEEDED FINANCING COULD AFFECT OUR ABILITY TO PURSUE FUTURE
GROWTH.

     We expect that our cash on hand, cash equivalents and proceeds from our
initial and secondary public offerings will be sufficient to meet our working
capital and capital expenditure needs for the foreseeable future. However, we
may need to raise additional funds to fund expansion, to respond to competitive
pressures or to acquire complementary products, businesses or technologies. We
cannot assure you that we would be able to obtain additional financing on
favorable terms, if at all. If we issue additional equity securities,
stockholders may experience additional dilution or the new equity securities may
have rights, preferences or privileges senior to those of existing holders of
common stock. If we cannot raise necessary

                                       30
<PAGE>   38

additional funds on acceptable terms, we may not be able to fund expansion, take
advantage of future opportunities or respond to competitive pressures or
unanticipated requirements.

OUR STOCK PRICE MAY BE VOLATILE, WHICH COULD LEAD TO LOSSES BY INVESTORS AND TO
SECURITIES LITIGATION.

     The market price of Broadbase common stock has been and is likely to
continue to be highly volatile due to several factors, such as:

     - variations in our actual and anticipated operating results;

     - changes in our earnings estimates by analysts;

     - our failure to meet analysts' performance expectations; and

     - the volume of trading in our common stock.

     In addition, stock markets, particularly the Nasdaq National Market, have
experienced extreme price and volume fluctuations, and the market prices of
securities of technology companies, particularly Internet-related companies,
have been highly volatile. These fluctuations have often been unrelated to the
operating performance of such companies. Fluctuations such as these may affect
the market price of Broadbase common stock. Substantial sales of Broadbase
common stock could also cause the stock price to decline.

     In the past, securities class action litigation has often been instituted
against companies following periods of volatility in their stock price. This
type of litigation could result in substantial costs and could divert our
management's attention and resources.

RISKS RELATED TO THE INDUSTRY OF THE COMBINED COMPANY

OUR BUSINESS DEPENDS ON THE GROWTH IN THE USE OF THE INTERNET FOR BUSINESS.

     Our future success depends heavily on the increased acceptance and use of
the Internet for business. Although the Internet is experiencing rapid growth in
the number of users and traffic, this growth is a recent phenomenon and may not
continue. Furthermore, despite this growth in usage, the use of the Internet for
business transactions is relatively new. If use of the Internet for business
does not continue to increase or increases more slowly than expected, our
business would be seriously harmed. Consumers and businesses may reject the
Internet as a viable commercial medium, or be slow to adopt it, for a number of
reasons, including potentially inadequate network infrastructure, slow
development of enabling technologies, concerns about the security of
transactions and confidential information and insufficient commercial support.
The Internet infrastructure may not be able to support the demands placed on it
by increased Internet usage and bandwidth requirements. In addition, delays in
the development or adoption of new standards and protocols required to handle
increased levels of Internet activity, or increased governmental regulation,
could cause the Internet to lose its viability as a commercial medium.

     If these or any other factors cause use of the Internet for business to
slow or decline, our business would be harmed. For example, Servicesoft's
products address a new and emerging market for e-service solutions. Therefore,
our future success depends substantially upon the widespread adoption of the
Internet as a significant medium for commerce and business applications. If this
market fails to develop or develops more slowly than expected, demand for our
products and services will be reduced. Even if the required infrastructure,
standards, protocols or complementary products, services or facilities are
developed, we may incur substantial expenses adapting our products and services
to changing or emerging technologies.

INCREASING GOVERNMENTAL REGULATION OF THE INTERNET COULD LIMIT THE MARKET FOR
OUR PRODUCTS.

     A number of legislative and regulatory proposals under consideration by
federal, state, local and foreign governmental organizations may lead to laws or
regulations concerning various aspects of the Internet, such as user privacy,
taxation of goods and services provided over the Internet, pricing, content and
quality of products and services. Legislation could dampen the growth in
Internet usage and decrease or limit its acceptance as a communications and
commercial medium. If enacted, these laws and regulations could limit the market
for our products. In addition, existing laws could be applied to the Internet,
including consumer privacy laws. Legislation or application of existing laws
could expose companies involved in electronic commerce, or e-commerce, to
increased liability, which could limit the growth of e-commerce generally.

GOVERNMENT REGULATION OF THE COLLECTION AND USE OF PERSONAL DATA COULD REDUCE
DEMAND FOR OUR PRODUCTS.

     Our products connect to and analyze data from various applications,
including Internet applications, that enable businesses to capture and use
information about their customers. Government regulation which limits our
customers' use of this information could reduce the demand for our products. A
number of jurisdictions have adopted, or are considering adopting, laws that
restrict the use of customer information from Internet applications. The
European Union has required that its member states adopt legislation that
imposes restrictions on the collection and use of personal data, and that limits
the transfer of personally-identifiable data to countries that do not impose
equivalent restrictions. In the United States, the Children's Online Privacy
Protection Act was enacted in October 1998. This legislation directs the Federal
Trade Commission to regulate the collection of data from children on commercial
Web sites. In addition, the Federal Trade Commission has begun investigations
into the privacy practices of businesses that collect information on the
Internet. These and other privacy-related initiatives could reduce demand for
some of the Internet applications with which our products operate, and could
restrict the use of our products in some e-commerce applications. This could
reduce demand for our products.

                                       32
<PAGE>   40

THE IMPOSITION OF SALES AND OTHER TAXES ON PRODUCTS SOLD BY OUR CUSTOMERS OVER
THE INTERNET COULD HAVE A NEGATIVE EFFECT ON ONLINE COMMERCE AND THE DEMAND FOR
OUR PRODUCTS AND SERVICES.

     The imposition of new sales or other taxes could limit the growth of
Internet commerce generally and, as a result, the demand for our products and
services. Recent federal legislation limits the imposition of state and local
taxes on Internet-related sales. Congress may choose not to renew this
legislation in 2001, in which case state and local governments would be free to
impose taxes on electronically purchased goods. We believe that most companies
that sell products over the Internet do not currently collect sales or other
taxes on shipments of their products into states or foreign countries where they
are not physically present. However, one or more states or foreign countries may
seek to impose sales or other tax collection obligations on out-of-jurisdiction
companies that engage in e-commerce. A successful assertion by one or more
states or foreign countries that companies that engage in e-commerce should
collect sales or other taxes on the sale of their products over the Internet,
even though not physically in the state or country, could indirectly reduce
demand for our products.

PRIVACY CONCERNS RELATING TO THE INTERNET ARE INCREASING, WHICH COULD RESULT IN
LEGISLATION THAT NEGATIVELY AFFECTS OUR BUSINESS, IN REDUCED SALES OF OUR
PRODUCTS, OR BOTH.

     Businesses using our products capture information regarding their customers
when those customers contact them on-line with customer service inquiries.
Privacy concerns may cause visitors to resist providing the personal data
necessary to allow our customers to use our software products most effectively.
More importantly, even the perception of privacy concerns, whether or not valid,
may indirectly inhibit market acceptance of our products. In addition,
legislative or regulatory requirements may heighten these concerns if businesses
must notify Web site users that the data captured after visiting certain Web
sites may be used by marketing entities to unilaterally direct product promotion
and advertising to that user. While we are not aware of any such legislation or
regulatory requirements currently in effect in the United States, other
countries and political entities, such as the European Union, have adopted such
legislation or regulatory requirements and the United States may do so as well.
If consumer privacy concerns are not adequately addressed, our business could be
harmed.

ADDITIONAL RISKS RELATED TO SERVICESOFT'S BUSINESS

     In addition to the risks of the combined company described above, this
section describes additional risks related to Servicesoft's business in
particular.

A SMALL NUMBER OF CLIENTS ACCOUNT FOR A SUBSTANTIAL PORTION OF SERVICESOFT'S
REVENUE, AND IF SERVICESOFT LOSES ONE OR MORE OF THESE CLIENTS, ITS REVENUES
WILL BE AFFECTED NEGATIVELY.

     Historically, Servicesoft has derived a significant portion of its revenue
from providing products and services to a limited number of clients. For the six
months ended June 30, 2000, Servicesoft's five largest clients, InsLogic,
National Tech Team, Bell Atlantic, Citrix Systems and Akamai, accounted for
approximately 52% of its revenue. Servicesoft expects that a limited number of
clients will continue to account for a substantial portion of its revenues for
the foreseeable future. As a result, if Servicesoft loses a major client or if a
contract with a major client or prospect is delayed, cancelled, reduced or
deferred, Servicesoft's revenue will decline substantially.

SERVICESOFT EXPECTS TO DERIVE SUBSTANTIALLY ALL OF ITS REVENUE FOR THE
FORESEEABLE FUTURE FROM ITS SERVICESOFT 2001 SUITE OF PRODUCTS AND PROFESSIONAL
SERVICES, AND IF THESE PRODUCTS AND SERVICES ARE NOT WIDELY ACCEPTED BY THE
MARKET, SERVICESOFT MAY BE UNABLE TO SUSTAIN OR INCREASE ITS REVENUE.

     Servicesoft currently derives substantially all of its revenue from sales
of its Servicesoft 2000 family of products, which was released in the fourth
quarter of 1999, its Servicesoft 2001 suite of products, which was released in
the third quarter of 2000, and from its professional services. Servicesoft
expects that an increasing amount of Servicesoft's software license revenue will
be dependent upon market acceptance of the Servicesoft 2001 suite of products.
Servicesoft's target clients may not widely adopt and deploy the Servicesoft
2001 products and Servicesoft's services, because they may not value the
differentiating features of Servicesoft's products and services, such as
Servicesoft's knowledge base. Furthermore, Servicesoft's competitors may
introduce e-service products that are more appealing to Servicesoft's target
clients. If Servicesoft's products do not achieve and maintain broad market
acceptance, Servicesoft may be unable to sustain or increase its revenue.

CUSTOMER SATISFACTION AND DEMAND FOR SERVICESOFT'S PRODUCTS WILL DEPEND ON ITS
ABILITY TO EXPAND ITS PROFESSIONAL SERVICES GROUP, WHICH ASSISTS ITS CUSTOMERS
WITH THE IMPLEMENTATION OF ITS PRODUCTS.

     To date, customers that have licensed Servicesoft's software products have
typically engaged Servicesoft's professional services organization to assist
with support, training, consulting and implementation of their e-business
solutions. Servicesoft believes that growth in its product sales depends on its
ability to provide its customers with professional services to assist with
support, training, consulting and initial implementation of its products and to
educate third-party systems integrators in the use of its products. As a result,
Servicesoft plans to increase the number of professional services personnel to
meet these needs. New professional services personnel will require training and
take time to reach full productivity. Servicesoft may not be able to attract or
retain a sufficient number of highly qualified professional services personnel.
Competition for qualified professional services personnel with the appropriate
knowledge is intense. Servicesoft is in a new market and there is a limited
number of people who have the necessary skills. To meet its customers' needs for
professional services, Servicesoft may also need to use more costly third-party
consultants to supplement its own professional services group. To date,
Servicesoft's cost of services have been significantly higher than services
revenues, and Servicesoft expects this trend to continue for the foreseeable
future. In addition, Servicesoft could experience delays in recognizing revenue
if its professional services group falls behind schedule in connecting its
products to customers' systems and data sources.

                             THE BROADBASE MEETING

DATE, TIME, PLACE AND PURPOSE OF THE BROADBASE MEETING

     Broadbase Software, Inc. will hold a special meeting of its stockholders at
the Stanford Park Hotel located at 100 El Camino Real, Menlo Park, California,
on             ,             , 2000, at      a.m., Pacific Time. At the meeting,
Broadbase stockholders at the close of business on             , 2000 will be
asked:

     1. To approve the issuance of shares of Broadbase common stock in
        connection with its proposed acquisition of Servicesoft and adoption of
        Broadbase's first amended and restated certificate of incorporation,
        which will increase the authorized number of shares of Broadbase common
        stock from 90,000,000 to 350,000,000 shares. The merger agreement is
        attached as Annex A and Broadbase's first amended and restated
        certificate of incorporation is attached as Annex B.

     2. To approve an amendment to Broadbase's 1999 Equity Incentive Plan to
        increase the number of shares authorized and reserved for issuance under
        this plan by 4,000,000 shares.

     3. To approve an amendment to Broadbase's 1999 Employee Stock Purchase Plan
        to increase the number of shares authorized and reserved for issuance
        under this plan by 1,000,000 shares.

     Broadbase does not anticipate that any other matter will be presented for
action at the meeting. If any other matters are properly brought before the
meeting, the persons named in the proxies for the Broadbase meeting will have
discretion to vote on these matters in accordance with their respective
judgments.

NOTICE REQUIREMENTS

     Broadbase's bylaws provide that no business may be transacted at the
Broadbase special meeting unless it is set forth in the notice of the Broadbase
special meeting.

RECORD DATE AND OUTSTANDING SHARES

     The record date for the Broadbase stockholders' meeting is             ,
2000. Only holders of record of Broadbase common stock at the close of business
on the record date are entitled to notice of and to vote at the meeting. As of
the close of business on the record date, there were           shares of
Broadbase common stock outstanding and entitled to vote, held of record by
approximately           stockholders, although Broadbase has been informed that
there are in excess of           beneficial owners.

     On the record date, directors, executive officers and other affiliated
stockholders of Broadbase as a group beneficially owned           shares of
Broadbase common stock. These shares constituted approximately      % of all of
the outstanding shares of Broadbase common stock as of the record date.

VOTE AND QUORUM REQUIREMENTS

     Each Broadbase stockholder is entitled to one vote for each share of
Broadbase common stock held as of the record date.

     Proposal No. 1 -- Issuance of Shares in the Servicesoft Acquisition and
Amendment to Broadbase's Certificate of Incorporation.  This proposal must be
approved by the holders of a majority of the shares of Broadbase common stock
outstanding as of the record date.

     Proposal No. 2 -- Amendment to Broadbase's 1999 Equity Incentive
Plan.  This proposal must be approved by the holders of a majority of the shares
of Broadbase common stock held by those present at the meeting or represented by
proxy at the meeting that are voted "for," "against" or "abstain" on this
proposal.

     Proposal No. 3 -- Amendment to Broadbase's 1999 Employee Stock Purchase
Plan.  This proposal must be approved by the holders of a majority of the shares
of Broadbase common stock held by those present at the meeting or represented by
proxy at the meeting that are voted "for," "against" or "abstain" on this
proposal.

     Quorum.  The holders of a majority of the shares of Broadbase common stock
entitled to vote at the Broadbase stockholders' meeting, present in person or
represented by proxy, will constitute a quorum for the purposes of the meeting.

     Effect of Abstentions and Broker Non-Votes.  Abstentions will have the same
effect as votes against the proposals. If a broker, bank, custodian, nominee or
other record holder of Broadbase common stock indicates on a proxy that it does
not have discretionary authority to vote shares on a particular matter, which is
called a broker non-vote, those shares will be counted for purposes of
determining the presence or absence of a quorum for the Broadbase stockholders'
meeting, which will have the same effect as votes against Proposal No. 1, but
will not be considered present at the meeting with respect to Proposal No. 2 and
Proposal No. 3 and therefore will have no effect on these proposals.

     Broadbase stockholders holding approximately   % of the outstanding shares
of Broadbase common stock as of the record date have agreed to vote all of their
shares of Broadbase common stock in favor of Proposal No. 1. See the section
entitled "Related Agreements -- Voting Agreements" beginning on page 88.

     In the event that sufficient votes in favor of the proposals are not
received by the date of the meeting, the persons named as proxies may propose
one or more adjournments of the meeting to permit further solicitation of
proxies. Adjournment would require the affirmative vote of the holders of a
majority of the outstanding shares of Broadbase common stock present in person
or represented by proxy at the Broadbase stockholders' meeting.

VOTING AND REVOCABILITY OF PROXIES

     The proxy relating to the Broadbase stockholders' meeting that accompanies
this document is solicited on behalf of Broadbase's board of directors for use
at the Broadbase stockholders' meeting. Please complete, date and sign the
accompanying proxy card and promptly return it in the enclosed envelope or
otherwise mail it to Broadbase. All properly signed proxies that Broadbase
receives and that are not revoked prior to the vote at the Broadbase
stockholders' meeting will be voted at the meeting according to the instructions
indicated on the proxies or, if no vote is indicated, in favor of each proposal.
A Broadbase stockholder may revoke his or her proxy at any time before it is
exercised at the meeting by taking any of the following actions:

     - delivering to the secretary of Broadbase a written notice, bearing a date
       later than the date of the proxy, stating that the proxy is revoked;

     - signing and delivering to the secretary of Broadbase a proxy relating to
       the same shares and bearing a later date prior to the vote at the
       meeting; or

     - attending the Broadbase stockholders' meeting and voting in person,
       although attendance at the meeting will not, by itself, revoke a proxy.
       Please note, however, that if your shares are held of record by a broker,
       bank or other nominee and you wish to vote at the Broadbase stockholders'
       meeting, you must bring to the meeting a letter from the broker, bank or
       other nominee confirming your beneficial ownership of the shares.

EXPENSES OF PROXY SOLICITATION

     Broadbase will pay the expenses of soliciting proxies to be voted at the
Broadbase stockholders' meeting. Following the original mailing of the proxies
and other soliciting materials, Broadbase and its agents also may solicit
proxies by mail, telephone or in person. Also, Broadbase will request brokers,
custodians, nominees and other record holders of Broadbase common stock to
forward copies of the proxy

                                       36
<PAGE>   44

and other soliciting materials to persons for whom they hold shares of Broadbase
common stock and to request authority for the exercise of proxies. In these
cases, upon the request of the record holders, Broadbase will reimburse these
holders for their reasonable expenses.

NO DISSENTERS' OR APPRAISAL RIGHTS

     Holders of Broadbase common stock are not entitled to dissenters' rights or
appraisal rights with respect to any of the proposals to be considered at the
Broadbase stockholders' meeting.

    PROPOSAL NO. 1 -- ISSUANCE OF SHARES IN THE SERVICESOFT ACQUISITION AND
             AMENDMENT TO BROADBASE'S CERTIFICATE OF INCORPORATION

THE MERGER

     Based on the capitalization of Servicesoft as of September 30, 2000 and the
exchange ratio of 1.4404, Broadbase will issue approximately 28,962,886 shares
of Broadbase common stock and options and warrants to acquire approximately
6,097,619 shares of Broadbase common stock in the merger. For more information
about this proposal, please refer to the sections entitled "The Merger"
beginning on page 50 and "The Merger Agreement" beginning on page 75. The merger
agreement is included as Annex A to this document.

AMENDMENT TO BROADBASE'S CERTIFICATE OF INCORPORATION

     Broadbase's certificate of incorporation currently authorizes Broadbase to
issue 90,000,000 shares of common stock and 5,000,000 shares of preferred stock.
On             , 2000, Broadbase's board of directors adopted Broadbase's first
amended and restated certificate of incorporation, subject to stockholder
approval. This new certificate of incorporation increases the number of shares
of common stock authorized for issuance to 350,000,000. Approval of this new
certificate of incorporation is required to complete the Servicesoft
acquisition. Broadbase's first amended and restated certificate of incorporation
is included as Annex B to this document.

  Current commitments for use of shares

     As of September 30, 2000, there were:

     - 50,466,772 shares of Broadbase common stock outstanding;

     - 475,366 shares of Broadbase common stock reserved for future issuance in
       connection with Broadbase's pending acquisition of Decisionism, Inc.;

     - 20,749,550 shares reserved for future issuance under employee stock
       option and employee stock purchase plans, of which 15,347,066 shares were
       subject to issuance upon the exercise of stock options currently
       outstanding or committed to be granted.

     Based upon these numbers, Broadbase has 18,308,312 shares of common stock
remaining available for other purposes. However, based on the capitalization of
Servicesoft as of September 30, 2000 and an exchange ratio of 1.4404, Broadbase
will need approximately 40,060,505 shares available for issuance in the
Servicesoft acquisition and shares to be issued upon the exercise of stock
options and purchase rights to be issued in the future if Proposal No. 2 and
Proposal No. 3 are approved. Therefore, without amending its certificate of
incorporation to authorize additional shares of common stock, Broadbase would
not have a sufficient number of shares authorized for issuance to complete the
Servicesoft acquisition and for purposes of Proposals 2 and 3.

  Purpose and possible effects of the amendment

     Purpose of Increasing the Authorized Stock.  Broadbase's board of directors
believes that it is in Broadbase's best interests to increase the number of
shares of common stock that it is authorized to issue in order to give Broadbase
the number of shares required to complete the Servicesoft acquisition and to
reserve shares for issuance upon the exercise of options and purchase rights to
be issued in the future if Proposal No. 2 and Proposal No. 3 are approved.

     Broadbase's board also believes that the availability of additional
authorized shares will provide Broadbase with the flexibility to undertake
various types of transactions in the future, including equity capital
financings, future acquisitions of companies, adopting additional employee
benefit plans or increasing the shares reserved for issuance under employee
benefit plans, or stock splits in the form of stock dividends. The additional
shares of authorized common stock would be available for issuance by

                                       38
<PAGE>   46

Broadbase without further stockholder action, unless required by applicable law
or the rules of any stock exchange or national securities association trading
system on which Broadbase common stock is then listed or quoted. Broadbase has
no current plans to issue the remainder of the additional authorized shares
other than shares issued in connection with exercises of options currently
outstanding or to be issued in the future under its employee benefit plans, and
in connection with its pending acquisition of Decisionism.

     Dilutive Effect of Potential New Stock Issuances.  Broadbase's stockholders
do not have preemptive rights with respect to its common stock. Should
Broadbase's board of directors elect to issue additional shares of common stock
in the future, existing stockholders would not have any preferential rights to
purchase these shares. Therefore, additional issuances of Broadbase common stock
in the future could have a dilutive effect on the earnings per share, voting
power and share holdings of current stockholders.

     Potential Anti-takeover Effect of an Increase in Authorized Stock.  The
proposed increase in the authorized number of shares of Broadbase common stock
could, under some circumstances, have an anti-takeover effect, although this
proposal is prompted by business and financial considerations, rather than any
threat of an attempt to gain control of Broadbase. For example, in the event of
a hostile attempt to take over control of Broadbase, it may be possible for
Broadbase to seek to impede the attempt by issuing shares of its common stock,
which could dilute the voting power of the other outstanding shares and increase
the potential cost to acquire control of Broadbase. Therefore, the increase in
authorized shares may have the effect of discouraging unsolicited takeover
attempts. By potentially discouraging unsolicited takeover attempts, the
increase may limit the opportunity for the stockholders of Broadbase to dispose
of their shares at the higher price generally available in takeover attempts or
that may be available under a merger or acquisition proposal. The increase may
also have the effect of providing Broadbase's management, including its board of
directors, with extra security, and place it in a better position to resist
changes that stockholders may wish to make if they are dissatisfied with the
conduct of Broadbase's business. However, Broadbase's board of directors is not
aware of any attempt to take control of Broadbase and has not presented this
proposal with the intent that it be utilized as a type of anti-takeover device.

   BROADBASE'S BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSAL TO ISSUE
 SHARES IN THE SERVICESOFT ACQUISITION AND TO AMEND BROADBASE'S CERTIFICATE OF
                                 INCORPORATION.

     PROPOSAL NO. 2 -- AMENDMENT TO BROADBASE'S 1999 EQUITY INCENTIVE PLAN

     Broadbase is asking its stockholders to approve an amendment to Broadbase's
1999 Equity Incentive Plan to provide for an increase in the number of shares of
common stock reserved for issuance under the plan from 9,933,938 shares to
13,933,938 shares. Broadbase's board of directors believes the share increase is
necessary for Broadbase to continue to have a sufficient reserve of shares
available under the plan to attract and retain the services of key employees and
other qualified personnel essential to Broadbase's long-term success and to
compete effectively for qualified personnel in its markets. In particular,
Broadbase's board of directors believes that the share increase is necessary to
secure sufficient additional shares under the plan for option grants that it
believes will be necessary to retain key employees of Servicesoft after the
merger. Broadbase believes that approval of the increase under the 1999 Equity
Incentive Plan is critical to the success of the combined company after the
merger.

SUMMARY OF THE PLAN

     History of Broadbase's 1999 Equity Incentive Plan.  In July 1999,
Broadbase's board of directors adopted and its stockholders approved Broadbase's
1999 Equity Incentive Plan and reserved 7,000,000 shares of common stock for
issuance under the plan, and 1,128,930 shares reserved under the 1996 plan
became available for issuance under the 1999 Equity Incentive Plan upon its
adoption. The plan serves as the successor to Broadbase's 1996 Equity Incentive
Plan, which is referred to as the 1996 plan. On January 1, 2000, an automatic
increase of 1,805,008 shares reserved for issuance under the 1999 Equity
Incentive Plan became effective. On                  , 2000, Broadbase's board
of directors approved this proposed amendment to the 1999 Equity Incentive Plan,
subject to stockholder approval.

     As of September 30, 2000, options to purchase an aggregate of 8,551,976
shares of common stock were outstanding under the 1999 Equity Incentive Plan,
18,383 shares had been issued pursuant to options exercised and restricted stock
awards under the plan, and there were 1,363,579 shares available for issuance,
but not subject to outstanding options, under the plan. As of September 30,
2000, Broadbase had granted options to purchase an aggregate of 9,775,932 shares
under the plan to employees of Broadbase, including all current officers who are
not executive officers, which number includes options to purchase 2,420,000
shares granted to executive officers. Broadbase had also granted options to
purchase 120,000 shares to non-employee directors.

     2000 Equity Incentive Plan.  In May 2000, Broadbase's board of directors
adopted Broadbase's 2000 Stock Incentive Plan and reserved 3,000,000 shares of
common stock for issuance under this plan. This plan has been designed to meet
the "broadly based plans" exemption from the stockholder approval requirement
for stock option plans under the Nasdaq National Market listing requirements.
The terms of the plan are substantially similar to the terms of the 1999 Equity
Incentive Plan, except that this plan does not provide for grants of incentive
stock options that qualify under Section 422 of the Internal Revenue Code, no
more than 40% of the shares reserved for grant under this plan may be issued to
Broadbase officers, and no more than 40% of all restricted stock awards under
this plan may be made to Broadbase officers.

     Shares Subject to the 1999 Equity Incentive Plan.  If this amendment is
approved, the total number of shares of common stock reserved for issuance under
the plan will be 13,933,938, plus:

     - shares issued under the 1996 plan that are forfeited by the holder or
       repurchased by Broadbase; and

     - shares subject to options granted under the 1996 plan that expire or
       become unexercisable for any reason.

In addition, on January 1 of each year beginning in 2000, the shares reserved
for issuance under the 1999 Equity Incentive Plan will be increased
automatically by 5% of the total outstanding shares of Broadbase common stock as
of the immediately preceding December 31, provided that no more than 20,000,000
shares may be issued upon exercises of incentive stock options. The number of
shares reserved for issuance under the plan is subject to proportional
adjustment to reflect stock splits, stock dividends and other similar events.
                                       40
<PAGE>   48

     Shares will again be available for grant and issuance under the 1999 Equity
Incentive Plan if they:

     - are issuable upon exercise of an option granted under this plan that
       cease to be subject to such option for any reason other than exercise of
       such option;

     - are subject to an award granted under this plan but are forfeited or are
       repurchased by us at the original issue price; or

     - are subject to any other award granted under this plan that otherwise
       terminates without shares being issued.

     Types of Awards.  The 1999 Equity Incentive Plan authorizes the award of:

     - stock options;

     - restricted stock awards, which are offers by Broadbase to sell shares of
       common stock subject to a right of repurchase by Broadbase or other
       restrictions on ownership or transfer; and

     - stock bonuses, which are awards of shares, which may be subject to the
       restrictions described above, for services rendered to Broadbase or any
       parent or subsidiary of Broadbase.

     Termination.  The 1999 Equity Incentive Plan will terminate in July 2009,
unless terminated beforehand by the board.

     Eligibility.  The plan provides for the grant of both incentive stock
options that qualify under section 422 of the Internal Revenue Code and
nonqualified stock options. Incentive stock options may be granted only to
employees of Broadbase or of a parent or subsidiary of Broadbase. Nonqualified
stock options, restricted stock awards or stock bonuses may be granted to
employees, officers, directors, consultants, independent contractors and
advisors of Broadbase or any parent or subsidiary of Broadbase, provided such
consultants, independent contractors and advisors render bona fide services not
in connection with the offer and sale of securities in a capital-raising
transaction. No person will be eligible to receive more than 2,000,000 shares in
any calendar year pursuant to awards under the plan other than a new employee of
Broadbase or a parent or subsidiary of Broadbase, who will be eligible to
receive no more than 3,000,000 shares in the calendar year in which such
employee commences employment. The administrator of the plan has the authority
to determine the restrictions applied to the stock.

     Automatic Grants to Directors.  Each person who becomes a non-employee
director of Broadbase will automatically be granted an option to purchase 10,000
shares of Broadbase common stock. Immediately following each annual meeting of
Broadbase stockholders, all non-employee directors will automatically be granted
an option to purchase 10,000 shares of Broadbase common stock, provided the
non-employee director has served continuously as a director for at least one
year. Each stock option will be 100% vested and immediately exercisable on the
date of grant. The exercise price of each option will be equal to the closing
price of Broadbase common stock on the date of grant.

STANDARD TERMS OF OPTIONS

     - Vesting.  Options under the plan generally become exercisable or vest
       over a four-year period.

     - Expiration Date.  The maximum term of options granted under the plan is
       ten years.

     - Exercise Price.  The exercise price of incentive stock options must be at
       least equal to the fair market value of Broadbase common stock on the
       date of grant. The exercise price of incentive stock options granted to
       10% stockholders must be at least equal to 110% of that value. The
       exercise price of nonqualified stock options must be at least equal to
       85% of the fair market value of Broadbase common stock on the date of
       grant.

                                       41
<PAGE>   49

     - Option Exercise and Payment Alternatives.  To exercise an option, the
       optionee must deliver to us an executed stock option exercise agreement
       and full payment for the shares being purchased. Subject in some cases to
       approval by the compensation committee, payment may be made:

        -- in cash or by check;

        -- by cancellation of indebtedness of Broadbase to the optionee;

        -- by surrender of fully paid shares of Broadbase common stock that have
           been owned by the optionee for more than six months, or were obtained
           in the public market;

        -- by tender of a full recourse promissory note, provided that
           participants who are not employees or directors of Broadbase may not
           purchase shares with a note unless it is secured by collateral other
           than the shares;

        -- by waiver of compensation due or accrued to an optionee for services
           rendered;

        -- through a same day sale;

        -- through a margin commitment; or

        -- through any combination of the foregoing.

     - Termination of Employment.  Options granted under the plan generally
       expire three months after the termination of the optionee's service to
       Broadbase or a parent or subsidiary of Broadbase, except that if the
       optionee is terminated for cause, options expire on the date of such
       termination. However, in the case of death or disability, options
       generally may be exercised up to 12 months following the date of death or
       termination of service. Options cease vesting on the date of death or
       termination of service.

     - Change in Control.  In the event one or more of the corporate
       transactions specified in the plan occurs, any or all outstanding awards
       may be assumed or replaced by the successor corporation. The successor
       corporation may also substitute equivalent awards or provide
       substantially similar consideration to option holders as was provided to
       stockholders in the transaction. Any awards that are not assumed or
       replaced, or substituted with other awards or similar consideration, will
       expire upon the consummation of the transaction, except for awards that
       the Broadbase compensation committee deems shall accelerate in the event
       of such a transaction.

UNITED STATES FEDERAL INCOME TAX INFORMATION

     THE FOLLOWING IS A GENERAL SUMMARY AS OF THE DATE OF THIS PROXY STATEMENT
OF THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO BROADBASE AND
PARTICIPANTS UNDER THE 1999 EQUITY INCENTIVE PLAN. THE FEDERAL TAX LAWS MAY
CHANGE AND THE FEDERAL, STATE AND LOCAL TAX CONSEQUENCES FOR ANY PARTICIPANT
WILL DEPEND UPON HIS OR HER INDIVIDUAL CIRCUMSTANCES. EACH PARTICIPANT HAS BEEN
AND IS ENCOURAGED TO SEEK THE ADVICE OF A QUALIFIED TAX ADVISOR REGARDING THE
TAX CONSEQUENCES OF PARTICIPATION IN THE PLAN.

     Incentive Stock Options.  A participant will recognize no income upon grant
of an incentive stock option and will incur no tax on its exercise unless the
participant is subject to the alternative minimum tax. If the participant holds
the stock acquired upon exercise of an incentive stock option, or the incentive
stock option shares, for more than one year after the date the option was
exercised and for more than two years after the date the option was granted, the
participant generally will realize long-term capital gain or loss, rather than
ordinary income or loss, upon disposition of the incentive stock option shares.
This gain or loss will be equal to the difference between the amount realized
upon such disposition and the amount paid for the incentive stock option shares.

     If the participant disposes of incentive stock option shares prior to the
expiration of either required holding period, which is referred to as a
disqualifying disposition, the gain realized upon such disposition, up to the
difference between the fair market value of the incentive stock option shares on
the date of exercise and the option exercise price, will be treated as ordinary
income. Any additional gain will be long-

                                       42
<PAGE>   50

term or short-term capital gain, depending upon the amount of time the incentive
stock option shares were held by the participant.

     The difference between the fair market value of the incentive stock option
shares on the date of exercise and the exercise price is an adjustment to income
for purposes of the alternative minimum tax. The alternative minimum tax, which
is imposed to the extent it exceeds the taxpayer's regular tax, is 26% of an
individual taxpayer's alternative minimum taxable income and 28% in the case of
alternative minimum taxable income in excess of $175,000. Alternative minimum
taxable income is determined by adjusting regular taxable income for certain
items, increasing that income by certain tax preference items, including the
difference between the fair market value of the incentive stock option shares on
the date of exercise and the exercise price, and reducing this amount by the
applicable exemption amount, $45,000 in case of a joint return, subject to
reduction under certain circumstances. If a disqualifying disposition of the
incentive stock option shares occurs in the same calendar year as exercise of
the incentive stock option, there is no alternative minimum tax adjustment with
respect to those incentive stock option shares. Also, upon a sale of incentive
stock option shares that is not a disqualifying disposition, alternative minimum
taxable income is reduced in the year of sale by the excess of the fair market
value of the incentive stock option shares at exercise over the amount paid for
the incentive stock option shares.

     Nonqualified Stock Options.  A participant will not recognize any taxable
income at the time a nonqualified stock option is granted. However, upon
exercise of a nonqualified stock option, the participant must include in income
as compensation an amount equal to the difference between the fair market value
of the shares on the date of exercise and the participant's exercise price. The
included amount must be treated as ordinary income by the participant and may be
subject to withholding by Broadbase, either by payment in cash or withholding
out of the shares to be received. Upon resale of the shares by the participant,
any subsequent appreciation or depreciation in the value of the shares will be
treated as capital gain or loss.

     Tax Treatment of Broadbase.  Broadbase generally will be entitled to a
deduction in connection with the exercise of a nonqualified stock option by a
participant to the extent that the participant recognizes ordinary income and
Broadbase withholds tax. Broadbase will be entitled to a deduction in connection
with the disposition of incentive stock option shares only to the extent that
the participant recognizes ordinary income on a disqualifying disposition of the
incentive stock option shares.

  ERISA

     The plan is not subject to any of the provisions of the Employee Retirement
Income Security Act of 1974.

 BROADBASE'S BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSED AMENDMENT TO
                    BROADBASE'S 1999 EQUITY INCENTIVE PLAN.

        PROPOSAL NO. 3 -- AMENDMENT OF 1999 EMPLOYEE STOCK PURCHASE PLAN

     Stockholders are being asked to approve an amendment to Broadbase's 1999
Employee Stock Purchase Plan to increase the number of shares of common stock
reserved for issuance under the plan from 1,361,000 shares to 2,361,000 shares.
Broadbase's board of directors believes the share increase is necessary for
Broadbase to continue to have a sufficient reserve of shares available under the
plan to attract and retain the services of key employees and other qualified
personnel essential to Broadbase's long-term success and to effectively compete
for qualified personnel in its markets. In particular, because Servicesoft does
not currently offer a similar plan to its employees, Broadbase's board of
directors believes that the share increase is necessary in order to allow
Servicesoft employees to participate in Broadbase's 1999 Employee Stock Purchase
Plan after the merger. Broadbase believes that approval of the increase under
the plan is critical to the success of the combined company after the merger.

SUMMARY OF THE PLAN

     History of Broadbase's 1999 Employee Stock Purchase Plan. Broadbase's board
of directors adopted and stockholders approved Broadbase's 1999 Employee Stock
Purchase Plan and reserved 1,000,000 shares of common stock for issuance under
the plan. On January 1, 2000, an automatic increase of 361,000 shares reserved
for issuance under the 1999 Employee Stock Purchase Plan became effective. On
         , 2000, Broadbase's board of directors approved this proposed amendment
to the 1999 Employee Stock Purchase Plan, subject to stockholder approval.

     Purpose. The plan has been established to provide employees of Broadbase
and its subsidiaries designated by the board as eligible to participate in the
plan with a convenient means of acquiring an equity interest in Broadbase, to
enhance such employees' sense of participation in our affairs and to provide an
incentive for continued employment. Participating employees may purchase shares
of our common stock from Broadbase at a discount from the market price and to
pay for these shares through payroll deductions.

     Termination. The plan will terminate in July 2009, unless terminated
beforehand by the board or unless all shares reserved for issuance under the
plan are issued prior to this date.

     Eligibility. All employees of Broadbase, or any parent or subsidiary, are
eligible to participate in an offering period (defined below) under the plan,
except the following:

     - employees who are not employed by Broadbase 10 days before the beginning
       of such offering period;

     - employees who are customarily employed for 20 hours or less per week;

     - employees who are customarily employed for five months or less in a
       calendar year; and

     - employees who own stock or hold options to purchase stock or who, as a
       result of participation in the plan, would own stock or hold options to
       purchase stock, possessing 5% or more of the total combined voting power
       or value of all classes of our capital stock.

     As of September 30, 2000, approximately 307 persons were eligible to
participate in the plan and 157,990 shares had been issued to our employees
pursuant to the plan. As of that date, 1,203,010 shares were available for
future issuance under the plan, not including the proposed amendment to the
plan. As of September 30, 2000, Broadbase had granted an aggregate of 16,542
shares under this plan to its executive officers, and Broadbase had granted no
shares to non-employee directors.

     Participating employees participate in the plan through payroll deductions.
A participating employee sets the rate of such payroll deductions, which may not
be less than 2% nor more than 10% of the participating employee's base salary,
commissions, bonuses and shift premiums; provided, however, that for purposes of
determining a participant's compensation, any election by that participant to
reduce his or her regular cash remuneration under Sections 125 or 401(k) of the
Internal Revenue Code shall be treated as if the participant did not make this
election. No participating employee is permitted to purchase shares

                                       44
<PAGE>   52

under the plan at a rate which, when aggregated with such employee's rights to
purchase stock under all similar purchase plans of Broadbase, exceeds $25,000 in
fair market value determined as of the offering date for each calendar year in
which a participating employee participates in the plan.

     Offering Period. Each offering under the plan will be for a period of 24
months. Offering periods begin on February 1 and August 1 of each year. Each
offering period generally consists of four six-month purchase periods during
which payroll deductions of the participating employees are accumulated under
the plan. The board has the power to set the beginning of any offering period
and to change dates or the duration of offering periods or purchase periods
without stockholder approval if such change is announced at least 15 days before
the scheduled beginning of the first offering period or purchase period to be
affected. The first day of each offering period is the offering date for such
offering period and the last business day of each purchase period is the
purchase date for such purchase period.

     Participating employees will participate in the purchase plan during each
offering period through regular payroll deductions as described above.
Participating employees may elect to participate in any offering period by
enrolling as provided under the terms of the plan. Once enrolled, a
participating employee will automatically participate in each succeeding
offering period unless the participating employee withdraws from the offering
period or the plan is terminated. After the rate of payroll deductions for an
offering period has been set by a participating employee, that rate will
continue to be effective for the remainder of the offering period and for all
subsequent offering periods in which the participating employee is automatically
enrolled unless otherwise changed by the participating employee. A participant
may increase or decrease the rate of payroll deductions at any time during a
purchase period, which change will continue for the remainder of the offering
period, unless changed in a subsequent purchase period. Only one change in the
rate of payroll deductions may be made during a purchase period. Participating
employees may not purchase more than twice the number of shares the
participating employee would have been eligible to purchase at 85% of the market
price of a share on the offering date if the market price of a share on the
purchase date drops to less than one-half of the market price on the offering
date. If the number of shares calculated for purchase on a purchase date exceeds
the number of shares available for issuance under the plan, Broadbase will make
a pro rata allocation of the shares among participating employees.

     Purchase Price. The purchase price of shares that may be acquired in any
purchase period under the plan will be 85% of the lesser of: (1) the fair market
value of the shares on the offering date; or (2) the fair market value of the
shares on the purchase date. The fair market value of a share of the common
stock is deemed to be the closing price of the common stock on the Nasdaq
National Market on the date of determination as reported in The Wall Street
Journal. As of October 18, 2000, the closing price of Broadbase common stock as
quoted on the Nasdaq National Market was $10.19 per share.

     Capitalization Events. The number of shares reserved for issuance under the
plan is subject to proportional adjustment to reflect stock splits, stock
dividends and other similar events.

UNITED STATES FEDERAL INCOME TAX INFORMATION

     THE FOLLOWING IS A GENERAL SUMMARY AS OF THE DATE OF THIS PROXY STATEMENT
OF THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO BROADBASE AND EMPLOYEES
PARTICIPATING IN THE 1999 EMPLOYEE STOCK PURCHASE PLAN. FEDERAL TAX LAWS MAY
CHANGE AND THE FEDERAL, STATE AND LOCAL TAX CONSEQUENCES FOR ANY PARTICIPATING
EMPLOYEE WILL DEPEND UPON HIS OR HER INDIVIDUAL CIRCUMSTANCES. EACH
PARTICIPATING EMPLOYEE HAS BEEN AND IS ENCOURAGED TO SEEK THE ADVICE OF A
QUALIFIED TAX ADVISER REGARDING THE TAX CONSEQUENCES OF PARTICIPATION IN THE
PLAN.

     The 1999 Employee Stock Purchase Plan is intended to qualify as an
"employee stock purchase plan" within the meaning of Section 423 of the Internal
Revenue Code.

     Tax Treatment of the Participating Employee. Participating employees will
not recognize income for federal income tax purposes either upon enrollment in
the plan or upon the purchase of shares. All tax

                                       45
<PAGE>   53

consequences are deferred until a participating employee sells the shares,
disposes of the shares by gift or dies.

     If shares are held for more than one year after the date of purchase and
more than two years from the beginning of the applicable offering period, or if
the participating employee dies while owning the shares, the participating
employee realizes ordinary income on a sale, or a disposition by way of gift or
upon death, to the extent of the lesser of: (1) 15% of the fair market value of
the shares at the beginning of the offering period; or (2) the actual gain (the
amount by which the market value of the shares on the date of sale, gift or
death exceeds the purchase price). All additional gain upon the sale of shares
is treated as long-term capital gain. If the shares are sold and the sale price
is less than the purchase price, there is no ordinary income and the
participating employee has a long-term capital loss for the difference between
the sale price and the purchase price.

     If the shares are sold or are otherwise disposed of including by way of
gift, but not death, bequest or inheritance, within either the one-year or the
two-year holding periods described above, which is referred to as a
disqualifying disposition, the participating employee realizes ordinary income
at the time of sale or other disposition, taxable to the extent that the fair
market value of the shares at the date of purchase is greater than the purchase
price. This excess will constitute ordinary income (not currently subject to
withholding) in the year of the sale or other disposition even if no gain is
realized on the sale or if a gratuitous transfer is made. The difference, if
any, between the proceeds of sale and the aggregate fair market value of the
shares at the date of purchase is a capital gain or loss. Capital gains may be
offset by capital losses, and up to $3,000 of capital losses may be used
annually against ordinary income.

     Tax Treatment of Broadbase. Broadbase will be entitled to a deduction in
connection with the disposition of shares acquired under the plan only to the
extent that the participating employee recognizes ordinary income on a
disqualifying disposition of the shares. Broadbase will treat any transfer of
record ownership of shares as a disposition, unless Broadbase is notified to the
contrary. In order to enable Broadbase to learn of disqualifying dispositions
and ascertain the amount of the deductions to which Broadbase is entitled,
participating employees will be required to notify Broadbase in writing of the
date and terms of any disposition of shares purchased under the plan.

ERISA

     The plan is not subject to any of the provisions of Employee Retirement
Income Security Act of 1974, nor is it qualified under Section 401(a) of the
Internal Revenue Code.

     The approval of the amendment to the plan requires the affirmative vote of
the holders of a majority of the total voting power of the shares of common
stock represented in person or by proxy at the meeting and entitled to vote on
this proposal.

 BROADBASE'S BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSED AMENDMENT TO
                 BROADBASE'S 1999 EMPLOYEE STOCK PURCHASE PLAN.

                               NEW PLAN BENEFITS

     The amounts of future option and share grants under Broadbase's 1999 Equity
Incentive Plan and future purchases under Broadbase's 1999 Employee Stock
Purchase Plan to and by our executive officers, directors and employees are not
determinable because under the terms of the 1999 Equity Incentive Plan such
grants are made in the discretion of Broadbase's board of directors or the
compensation committee, and under the terms of the 1999 Employee Stock Purchase
Plan such purchases are based on participant contributions. Future option
exercise and share purchase prices under the 1999 Equity Incentive Plan are not
determinable because they are based upon the fair market value of Broadbase
common stock on the date of grant, and future purchase prices under the 1999
Employee Stock Purchase Plan are not determinable because they are based on the
fair market value of Broadbase common stock at the beginning of each offering
period and on each purchase date.

                                   THE MERGER

     This section describes aspects of the proposed merger and the merger
agreement. While Broadbase and Servicesoft believe that the description covers
the material terms of the merger and the related transactions, it may not
contain all of the information that is important to you. You should read this
entire document and the other documents we refer to carefully for a more
complete understanding of the merger.

BACKGROUND OF THE MERGER

     Broadbase completed its initial public offering in September 1999, and
since then has acquired several companies in order to expand the breadth of its
product offerings or otherwise complement its business. In February 2000,
Broadbase acquired Rubric, Inc., a developer of products that automate planning,
execution and measurement of Internet-based marketing campaigns. In June 2000,
Broadbase acquired Aperio, Inc., a provider of e-commerce marketing solutions.
In September 2000, Broadbase acquired Panopticon, Inc., a developer of software
that produces real-time, context-sensitive, personalized recommendations across
web, wireless, e-mail and call center customer interaction points. Also, in
August 2000, Broadbase entered into a definitive agreement to acquire
Decisionism, Inc., a provider of software that enables business-to-business
e-commerce companies to incorporate analytical tools in their web sites to
assist customers in making decisions with respect to product purchases.

     Before the merger discussions between Broadbase and Servicesoft began,
Servicesoft was in the registration process for an initial public offering of
its common stock. Servicesoft had selected Morgan Stanley & Co. Incorporated to
act as the lead underwriter for its proposed offering in January 2000, and filed
its initial registration statement with the SEC on February 15, 2000. It filed
several amendments to the registration statement during the period from March
2000 through August 2000. However, in July 2000, Servicesoft decided to delay
the offering due to poor market conditions for initial public offerings of
Internet-related software companies. During the registration period, Servicesoft
continued to search for ways to build its business, including considering other
possible business relationships, and in July 2000, representatives of Morgan
Stanley suggested to Servicesoft that it might pursue a relationship with
Broadbase or a similar company.

     On July 14, 2000, Massood Zarrabian, Servicesoft's President and Chief
Executive Officer, called Chuck Bay, Broadbase's President and Chief Executive
Officer, described Servicesoft's business and raised the possibility of creating
a relationship between Broadbase and Servicesoft. Mr. Bay replied indicating
interest in discussing the possibility of a relationship.

     On July 26, 2000, representatives of Broadbase met with Gene Zylkuski,
Servicesoft's Vice President of Product Operations and other Servicesoft
engineers to discuss the companies' respective products and technology and
possible product integration. On August 2, 2000, Mr. Zarrabian and Mr. Bay met
to review and discuss possible markets, customers and business strategies that
could result from an alliance between Broadbase and Servicesoft. On August 10,
2000, Mr. Bay and Brian Kelly, Broadbase's Executive Vice President of Product
Strategy, met with Mr. Zarrabian, Mr. Zylkuski and other Servicesoft engineers
to view a demonstration of Servicesoft's products and continue discussions of
possible strategic alliances.

     From August 10 to August 20, 2000, Mr. Bay discussed approaches to a
strategic alliance between Broadbase and Servicesoft with various members of
Broadbase's executive management and with members of Broadbase's board of
directors. On August 11, 2000, Mr. Bay and a representative of Morgan Stanley
discussed the potential risks and benefits of a strategic alliance and a
possible business combination with Servicesoft. Later that day, Mr. Bay
contacted Mr. Zarrabian and suggested the possibility of a business combination,
and Mr. Zarrabian replied indicating his interest in pursuing a possible
transaction.

     On August 15, 2000, Broadbase formally retained Morgan Stanley to act as a
financial advisor in connection with a possible transaction with Servicesoft.
Broadbase was aware that Morgan Stanley had acted as a lead underwriter and a
financial advisor to Servicesoft before it engaged Morgan Stanley to act as its
financial advisor and Broadbase's board of directors consented to Morgan
Stanley's role and the use of separate teams by Morgan Stanley that shared
information regarding Broadbase and Servicesoft.

                                       50
<PAGE>   58

Broadbase was also aware, before engaging Morgan Stanley, that Morgan Stanley
owned a 0.55% equity interest in Servicesoft. Broadbase's decision to retain
Morgan Stanley was based on Morgan Stanley's reputation, its extensive knowledge
of Broadbase's business and its past relationship with Broadbase. Morgan Stanley
did not participate in the negotiation of the exchange ratio. The exchange ratio
was negotiated through arm's-length negotiations between Broadbase and
Servicesoft and was approved by each company's board of directors.

     On August 16, 2000, Broadbase and Servicesoft signed a confidentiality
agreement in order to facilitate the exchange of information and the detailed
evaluation of each other's business. From August 16, 2000 to August 30, 2000,
Mr. Bay and Mr. Zarrabian and their respective management teams continued
discussions regarding the desirability of a business combination between
Broadbase and Servicesoft and began discussing potential ranges of valuations
and other issues relating to a potential business combination. From August 21
through August 22, 2000, Chris Maeda, Broadbase's Executive Vice President of
Engineering, Brent Arslanger, Broadbase's Vice President of Product Strategy,
and other Broadbase engineers met with Mr. Zarrabian, Mr. Zylkuski and other
Servicesoft engineers and reviewed the possible technical integration of the two
companies.

     On August 28, 2000, Broadbase delivered to Servicesoft an outline of
principal terms for a proposed transaction between Broadbase and Servicesoft.
Also on August 28, Servicesoft held a special meeting of its board of directors
at which Servicesoft's management reviewed the possibility of a business
combination between Broadbase and Servicesoft, including the potential strategic
benefits and risks of such a transaction, Servicesoft's prospects as an
independent company and the likelihood of a successful initial public offering.
Representatives of Morgan Stanley and McDermott, Will & Emery, Servicesoft's
legal counsel, also attended the meeting. Following this discussion,
Servicesoft's board of directors authorized its representatives to proceed with
further discussions in connection with the potential transaction. Between August
28 and August 31, 2000, representatives of Broadbase and Servicesoft, including
their respective legal counsel, discussed and modified the principal terms of
the proposed transaction. However, no agreements were reached. Also during this
period, a director of Servicesoft contacted another company to inquire whether
it was interested in pursuing a business combination with Servicesoft.

     At the August 31, 2000 meeting of Servicesoft's board of directors,
Servicesoft's management and its financial and legal advisors reviewed the
principal terms of the proposed merger with Broadbase. Servicesoft's board of
directors approved Servicesoft's execution of an agreement not to solicit
alternative acquisition transactions involving Servicesoft until the earlier of
September 23, 2000 or the approval and execution of a definitive merger
agreement with Broadbase, and Broadbase and Servicesoft signed the non-
solicitation agreement later that day. However, no final agreement on an
exchange ratio or other significant terms of the proposed transaction was
reached at this time.

     On September 1, 2000, Broadbase also directed its legal counsel, Fenwick &
West LLP, to prepare drafts of the definitive agreements and to conduct legal
due diligence.

     On September 5, 2000, Broadbase's legal counsel sent a draft merger
agreement to Servicesoft's legal counsel. From September 5 through September 18,
2000, Servicesoft's and Broadbase's respective legal counsel negotiated the
terms of the merger agreement and related agreements. During this period,
Broadbase and its legal and financial advisors conducted business, legal and
financial due diligence review of Servicesoft, and Servicesoft and its legal and
financial advisors conducted business, legal and financial due diligence review
of Broadbase. Also during this period, senior management of both companies held
numerous discussions regarding various business, financial, operational and
technical issues involved in combining the companies.

     On September 8, 2000, Broadbase retained Dain Rauscher Wessels to act as a
financial advisor and to render a fairness opinion to Broadbase's board of
directors. This fairness opinion is described in greater detail in "Opinion of
Broadbase's financial advisor" and the full opinion is provided in Annex F to
this document.

                                       51
<PAGE>   59

     On September 8, 2000, Servicesoft retained Morgan Stanley to render a
financial opinion to holders of shares of Servicesoft common stock in connection
with the merger. Prior to its engagement of Morgan Stanley, Servicesoft was
aware of the existing relationship between Morgan Stanley and Broadbase, and
Servicesoft's Board of Directors consented to Morgan Stanley's role and the use
of separate teams by Morgan Stanley that shared information regarding Broadbase
and Servicesoft. Servicesoft's decision to retain Morgan Stanley was based on
Morgan Stanley's reputation, its extensive knowledge of Servicesoft and its
industry and its past relationship with Servicesoft. Morgan Stanley's financial
opinion letter is described in greater detail in "Opinion of Servicesoft's
financial advisor" and the full opinion is provided in Annex G to this document.

     On September 11, 2000, Broadbase held a meeting of its board of directors
at which Mr. Zarrabian made a presentation regarding Servicesoft's business. Mr.
Zarrabian then left the meeting and Broadbase's management, financial and legal
advisors reviewed the status of negotiations and the principal terms of the
possible business combination. In addition, Servicesoft's management and
directors discussed Servicesoft's business and products, and the strategic
rationale for the proposed transaction. Following this discussion, Broadbase's
board of directors authorized its representatives to proceed with further
discussions and due diligence in connection with a possible transaction with
Servicesoft.

     Following this meeting, the companies and their legal counsel continued to
negotiate the terms of the merger agreement, including the conditions to the
merger, the obligations of Servicesoft and Broadbase not to solicit competing
proposals, termination fees in the event of termination of the merger agreement,
the terms of employment agreements with key Servicesoft executives and other
matters. The companies and their financial advisors also negotiated and made
preliminary calculations of the proposed exchange ratio, and Broadbase and its
advisors and counsel continued their due diligence review.

     Broadbase's board of directors held another meeting on September 15, 2000
at which Broadbase's management described the status and results of their due
diligence investigations and the status of negotiations of the merger agreement.
At this meeting, representatives of Fenwick & West reviewed the responsibilities
of the board of directors in considering the proposed transaction. Broadbase's
directors and management then discussed the strategic rationale and potential
benefits and risks of the proposed transaction. The board of directors
authorized management to continue their discussions with Servicesoft.

     On September 15, 2000, Servicesoft's board of directors held a meeting to
consider the proposed transaction. At the meeting, Servicesoft's legal counsel
reviewed the principal terms of the merger and summarized the material
provisions of the draft merger agreement. In addition, Morgan Stanley presented
its financial analysis and rendered its oral opinion to the board of directors,
later confirmed in writing, to the effect that, as of September 15, 2000 and
based on and subject to the considerations described in its opinion, the
exchange ratio set forth in the merger agreement was fair to holders of shares
of Servicesoft common stock from a financial point of view. Following this
discussion, the directors in attendance unanimously approved the merger and the
merger agreement, and determined to recommend that Servicesoft's stockholders
vote to approve the proposed transaction.

     On September 16, 2000, Broadbase's board of directors held a meeting at
which Dain Rauscher Wessels summarized the financial analyses it had performed
relating to the proposed transaction and rendered its oral opinion to the board
of directors, subsequently confirmed in writing as of September 18, 2000, as to
the fairness of the proposed exchange ratio in the merger to Broadbase and its
stockholders. On September 17 and 18, 2000, Broadbase's management, directors
and the financial advisors completed their due diligence review and analysis of
the transaction, and on September 18, 2000, the companies completed their
negotiation of the definitive agreements and calculated and reached final
agreement on the exchange ratio.

     On September 18, 2000, Broadbase's board of directors held a meeting at
which its legal advisors reviewed the principal terms of the merger agreement.
Following this discussion, Broadbase's board of directors approved the merger
agreement and related agreements. Broadbase's board of directors also determined
to recommend to the Broadbase stockholders that they approve the issuance of
shares of

                                       52

Broadbase common stock in the merger and the amendment of Broadbase's
certificate of incorporation, together with any other approvals required in
order to consummate the merger.

     On September 18, 2000, after the close of trading on the Nasdaq National
Market, the parties signed the merger agreement and the executive officers,
directors and affiliated stockholders of Broadbase and Servicesoft, as well as
certain significant stockholders of Servicesoft, executed voting agreements. The
parties then issued a joint press release announcing the transaction.

BROADBASE'S REASONS FOR THE MERGER

     At its meeting on September 18, 2000, the board of directors of Broadbase
unanimously concluded that the merger was in the best interests of Broadbase and
its stockholders, approved the execution and delivery of the merger agreement
and the issuance of the shares, together with the other actions necessary for
the merger to occur, and determined to recommend that its stockholders approve
the proposals relating to the merger.

     The decision of the board of directors of Broadbase was based upon a number
of potential benefits of the merger, including the following:

     - the complementary nature of the technologies, products and services of
       Broadbase and Servicesoft and the resulting opportunity to further
       Broadbase's strategic objective of transforming its software product
       offering from a marketing automation and analytics suite to a broad
       e-customer relationship management suite that integrates and addresses a
       more complete range of customer interactions;

     - the opportunity provided by the merger for Broadbase to strengthen and
       enhance its market position by offering a broad, integrated e-customer
       relationship management suite, as businesses are increasingly seeking to
       reduce the number of vendors from which they purchase software
       applications and services and to increase the degree of integration among
       the products they purchase, and as industry consolidation increases the
       size and product breadth of a number of other software companies;

     - the absence of a significant overlap of the customer bases of Servicesoft
       and Broadbase and the resulting opportunity provided by the merger to
       cross-sell products and services, offering existing customers of each
       company the products and services of the other and potentially increasing
       overall combined sales;

     - the potential advantages of Servicesoft's technology and products,
       including the fact that they combine an intelligent knowledge-base
       platform with e-service application modules, including self-help, and the
       fact that they integrate with multiple data systems to provide a complete
       customer view, each of which is consistent with Broadbase's intelligent
       customer interaction strategy;

     - the potential strategic synergies between Servicesoft's and Broadbase's
       intelligent customer interaction platforms and applications, which can
       provide Broadbase the opportunity to enhance its relationships with
       strategic partners and attract other such partners;

     - the service requirements associated with Servicesoft's knowledge-based
       solutions, which can enhance Broadbase's ability to attract and build
       upon relationships with system integrators;

     - the ability for Broadbase to expand its direct and indirect sales force
       and the opportunity for Broadbase to increase the productivity of the
       combined sales force by providing a broader range of products and
       services for the sales professionals to sell; and

     - the access that Broadbase would gain to Servicesoft's software engineers,
       professional service personnel, management and other employees.

                                       53

     In its evaluation of the merger, Broadbase's board of directors reviewed a
number of factors, including:

     - the benefits anticipated to be received by Broadbase and the potential
       dilution to Broadbase's stockholders in the merger;

     - the consideration that Servicesoft stockholders will receive in the
       merger as compared to similar merger transactions and the percentage
       ownership of the combined company by Broadbase's stockholders;

     - the strengths and limitations of Servicesoft's products, services and
       technology, including its recently introduced Servicesoft 2001 suite of
       products;

     - the status of existing customer deployment of Servicesoft's products;

     - Servicesoft's competitive position in the marketplace for e-customer
       service applications, market acceptance of its recently introduced
       Servicesoft 2001 suite of products and potential future demand for its
       products and services;

     - possible alternative means of achieving the anticipated benefits of the
       merger, including the possibility of a combination with a different
       provider of products and services for e-customer service applications,
       possible strategic alliances that would not involve a combination, and
       internal development of these products and services, including the
       feasibility of these alternatives, their potential timing and resource
       requirements;

     - trends of consolidation in Broadbase's market and the resultant increase
       in product breadth of Broadbase's competitors;

     - Broadbase's prospects without the merger or an alternative means of
       achieving its potential benefits;

     - historical information and the views of Broadbase's management and
       financial advisors concerning Broadbase's and Servicesoft's respective
       businesses, financial performance, operations, technology, products,
       management and prospects;

     - the expectations of Broadbase's management and financial advisors
       regarding possible reactions by Broadbase's stockholders to the
       announcement of the merger;

     - current financial market conditions and historical market prices,
       volatility and trading information with respect to Broadbase's common
       stock;

     - detailed financial analysis and pro forma and other information with
       respect to the companies presented to the board, including the opinion of
       Dain Rauscher Wessels that the exchange ratio would be fair from a
       financial point of view to Broadbase;

     - the anticipated impact of the merger on Broadbase's customers, strategic
       partners and employees; and

     - reports from management, legal, financial and accounting advisors as to
       the results of their due diligence investigations of Servicesoft.

     The Broadbase board of directors also identified and considered a number of
potentially negative factors in its deliberations concerning the merger
including the following:

     - the risk that the potential benefits of the merger may not be realized;

     - the risk that Broadbase would not be able to integrate Servicesoft's
       products and technology into its product offering and the risk that
       Broadbase would not be able to successfully develop enhanced or new
       products based on Servicesoft's technology;

     - the challenges of integrating the management teams, products,
       technologies, cultures and organizations of the two companies,
       particularly in view of their location in different geographic regions;

                                       54
<PAGE>   62

     - the risk of disruption of sales momentum as a result of the merger;

     - the risk of management and employee disruption as a result of the merger,
       including the risk that despite the efforts of the combined company, key
       technical, sales and management personnel might leave the combined
       company;

     - the risk that the merger could adversely affect Broadbase's or
       Servicesoft's relationships with customers and strategic partners;

     - the risk that the investment community may not immediately embrace the
       proposed combination, which could lead to a decline in Broadbase's stock
       price;

     - the possibility that the merger may not be approved, notwithstanding the
       voting agreements signed by large stockholders of both companies, or
       that, even if it is approved by the stockholders of both companies, the
       merger may not be completed;

     - the impact on Broadbase's financial statements of the one-time charges
       and amortization of goodwill and other intangible assets arising from the
       expected purchase accounting for the merger; and

     - other applicable risks described in this document under the heading "Risk
       Factors."

     Broadbase's board of directors concluded that, on balance, the potential
benefits to Broadbase and its stockholders of the merger outweighed the risks
associated with the merger. The discussion of the information and factors
considered by Broadbase's board of directors is not intended to be exhaustive.
In view of the variety of factors considered in connection with its evaluation
of the merger, Broadbase's board of directors did not find it practicable to,
and did not quantify or otherwise assign relative weight to, the specific
factors considered in reaching its determination.

RECOMMENDATION OF BROADBASE'S BOARD OF DIRECTORS

     After careful consideration, Broadbase's board of directors has determined
the merger agreement and the merger to be fair to and in the best interests of
Broadbase. In connection with the merger, Broadbase's board of directors
unanimously recommends approval of the issuance of shares of Broadbase common
stock in the merger and the amendment of Broadbase's certificate of
incorporation as described in this document.

SERVICESOFT'S REASONS FOR THE MERGER

     At the meeting of Servicesoft's board of directors on September 15, 2000,
the board voted unanimously to enter into the merger agreement. The board of
directors of Servicesoft unanimously concluded that the merger agreement and
merger are fair to and in the best interests of Servicesoft and its
stockholders, and determined to recommend that the stockholders of Servicesoft
vote to approve the merger and adopt the merger agreement. This decision was
based upon several potential benefits of the merger that Servicesoft's board
believes will contribute to the success of the combined company compared to
Servicesoft continuing to operate as an independent business. The decision of
the board of directors of Servicesoft was based upon several potential benefits
of the merger to Servicesoft and its stockholders, including the following:

     - the complementary nature of the technologies, products and services of
       Servicesoft and Broadbase and the resulting opportunity for Servicesoft
       to realize its strategic objectives;

     - the opportunity for Servicesoft's stockholders to participate in the
       potential for growth of the combined company after the merger, and to
       receive publicly-traded stock in the transaction, possibly providing them
       with an opportunity to realize a return on their investment sooner than
       if Servicesoft continued as a separate entity;

     - the possibility of providing a customer interaction software suite that
       integrates Servicesoft's technologies and products with Broadbase's
       marketing automation and analytics software and in

                                       55
<PAGE>   63

       doing so covers a broad range of the combined company's customers'
       demands and increases the likelihood that the companies can enhance the
       competitive position of their products;

     - the potential strategic synergies between Servicesoft's and Broadbase's
       intelligent customer interaction platforms and applications, which can
       provide Servicesoft the opportunity to enhance its relationships with
       strategic partners and attract other such partners;

     - the larger base of significant customers of the combined company, and the
       opportunity provided by the merger to cross-sell products and services,
       offering existing customers of each company the products and services of
       the other and potentially increasing overall sales;

     - the fact that, as of the date of the board meeting, the consideration to
       be received by Servicesoft's stockholders in the merger would be at a
       significant premium over the price most recently paid to Servicesoft for
       shares of its capital stock, and be comparable to the proposed price per
       share used by Servicesoft in its calculation of its registration fee for
       its registration statement on Form S-1;

     - in light of the volatility of the financial markets, particularly for the
       stock of companies like Servicesoft, the possibility that the merger
       could provide a faster and surer alternative, compared to the delayed
       initial public offering of its common stock, for Servicesoft to gain the
       resources it needs to continue growing its business and to maintain its
       competitive position;

     - the ability for Servicesoft to expand its direct and indirect sales force
       and to increase its sales quota capacity by providing Servicesoft access
       to Broadbase's team of sales professionals; and

     - the access that Servicesoft would gain to Broadbase's software engineers,
       professional service personnel, management and other employees.

     In its evaluation of the merger, the board of Servicesoft reviewed several
factors, including:

     - historical information and the views of Servicesoft's management and
       financial advisers concerning Servicesoft's and Broadbase's respective
       businesses, financial performance, operations, technology, products,
       management and prospects;

     - Servicesoft's management's view of the financial condition, results of
       operations and businesses of Servicesoft and Broadbase before and after
       giving effect to the merger and the board's determination of the merger's
       effect on stockholders;

     - the prospects of Servicesoft independent of Broadbase, including risks
       and potential rewards associated with remaining independent, including,
       among other things, the risks associated with continuing to wait for a
       public offering of its stock for its financing needs and with remaining
       independent in the face of industry-wide consolidation, and the rewards
       associated with maintaining an established marketing strategy and
       business organization and with the opportunity for existing stockholders
       of Servicesoft to participate in the future growth of Servicesoft;

     - possible alternative means of achieving the anticipated benefits of the
       merger, including the possibility of a combination with a different
       provider of customer analytics and e-marketing products, possible
       strategic alliances that would not involve a combination, and internal
       development of these products and services, including the feasibility of
       these alternatives, their potential timing and resource requirements;

     - Servicesoft's prospects without the merger or an alternative means of
       achieving its potential benefits;

     - the amount and form of the consideration that Servicesoft's stockholders
       would receive in the merger as compared to similar merger transactions
       and the percentage ownership of the combined company of Servicesoft's
       stockholders, including a comparison of the value of the consideration to
       be received by Servicesoft's stockholders and the prior implied values of
       Servicesoft's stock based on several metrics, including prices paid in
       the most recent sales of Servicesoft's securities and the valuation given
       to Servicesoft by its underwriters in its proposed public offering;

                                       56
<PAGE>   64

     - the expectations of Servicesoft's management and financial advisors
       regarding possible reactions by Servicesoft's stockholders to the
       announcement of the merger;

     - current financial market conditions and historical market prices,
       volatility and trading information with respect to Broadbase's common
       stock;

     - financial analysis and the opinion of Morgan Stanley & Co. Incorporated
       dated September 15, 2000 that, subject to and based on the considerations
       described in its opinion, the exchange ratio set forth in the merger
       agreement was fair from a financial point of view to holders of shares of
       Servicesoft common stock;

     - the anticipated impact of the merger on Servicesoft's customers,
       strategic partners and employees;

     - reports from management, legal, financial and accounting advisors as to
       the results of their due diligence investigations of Broadbase; and

     - the expectation that the merger would be accounted for as a purchase.

     Servicesoft's board of directors also identified and considered a number of
potentially negative factors in its deliberations concerning the merger,
including the following:

     - the risk that the potential benefits of the merger may not be realized;

     - the risk that Servicesoft would not be able to integrate Broadbase's
       products and technology into its product offering and the risk that
       Servicesoft would not be able to successfully develop enhanced or new
       products based on Broadbase's technology;

     - the possibility that the merger may not be approved, notwithstanding the
       voting agreements signed by certain large stockholders of both companies,
       and the possibility that, even if it is approved by the stockholders of
       both companies, the merger may not be completed;

     - the risk to Servicesoft's stockholders that Broadbase's trading prices
       could fall substantially before the merger is completed, decreasing the
       value of the merger consideration to the Servicesoft stockholders;

     - the risk of management and employee disruption resulting from the merger,
       including the risk that despite the efforts of the combined company, key
       technical, sales and management personnel might leave the combined
       company;

     - the risk of disruption of sales momentum as a result of the merger;

     - the challenges of integrating the management teams, products,
       technologies, cultures and organizations of the two companies,
       particularly in view of their location in different geographic regions;

     - the risk that the merger could adversely affect Broadbase's or
       Servicesoft's relationships with customers and strategic partners; and

     - other applicable risks described in this document under the heading "Risk
       Factors."

     Servicesoft's board of directors also evaluated the potential advantages
and disadvantages of completing an initial public offering of its common stock
as an alternative to pursuing the merger, including the following:

     - the value that stockholders could be expected to realize after an initial
       public offering, based on comparable public companies, relative to the
       consideration to be received in the merger;

     - uncertainties with respect to future market conditions and the
       receptivity of the market to Servicesoft's common stock; and

     - the anticipated restrictions on liquidity for Servicesoft's existing
       stockholders after an initial public offering relative to those after a
       merger.

unanimously determined that the terms of the merger are fair to and in the best
interests of Servicesoft and its stockholders and recommends to its stockholders
that they vote in favor of the proposal to approve and adopt the merger and the
merger agreement.

     In considering the recommendation of Servicesoft's board of directors with

are in addition to, the interests of Servicesoft's stockholders generally.

in the merger" beginning on page 68.

OPINION OF BROADBASE'S FINANCIAL ADVISOR

     On September 8, 2000, Broadbase retained Dain Rauscher Wessels (DRW), a
division of Dain Rauscher Incorporated, to act as financial advisor and to
furnish an opinion as to the fairness, from a financial point of view, of the
exchange ratio to Broadbase.

     On September 16, 2000, DRW rendered its oral opinion to Broadbase's board
of directors (subsequently confirmed in writing on September 18, 2000) that, as
of such date and based on the procedures followed, factors considered and
assumptions made by DRW and certain other limitations, the exchange ratio was
fair to Broadbase, from a financial point of view. A copy of DRW's written
opinion is attached as Annex F to this document. Broadbase stockholders are
urged to read the DRW opinion in its entirety. This summary of the opinion is
qualified in its entirety by reference to the full text of DRW's opinion.

     DRW's opinion applies only to the fairness to Broadbase, from a financial
point of view, of the exchange ratio. DRW's opinion was provided for the
information and assistance of Broadbase's board of directors in connection with
its consideration of the business combination. DRW's opinion was not prepared on
behalf of, and was not intended to confer rights or remedies upon, Broadbase,
Servicesoft, any stockholder of Broadbase or Servicesoft, or any persons other
than the Broadbase board of directors. DRW's opinion does not address the
relative merits of the business combination and any other transactions or
business strategies discussed by Broadbase's board of directors as alternatives
to the business combination, or the underlying business decision of Broadbase's
board of directors to proceed with the business combination. DRW's opinion and
presentation to the Broadbase board of directors were only two of many factors
taken into consideration by the Broadbase board of directors in making its
determination to approve the merger agreement. The opinion does not constitute a
recommendation to any stockholder as to how such stockholder should vote with
respect to the business combination. Broadbase's board of directors did not
impose any limitations on the scope of the investigation by DRW with respect to
rendering its opinion.

     In rendering its opinion, DRW assumed and relied upon the accuracy and
completeness of the financial, legal, tax, operating and other information
provided by Broadbase and Servicesoft including the financial statements and
related notes of Broadbase and Servicesoft. DRW did not assume responsibility
for independently verifying and did not independently verify this information.

     Additionally, DRW was not asked to and did not consider the possible
effects of any litigation, other legal claims or any other contingent matters.
DRW did not assume responsibility for and did not perform any independent
evaluation or appraisal of any of the respective assets or liabilities of
Broadbase or

                                       58
<PAGE>   66

Servicesoft, nor was DRW furnished with any evaluations or appraisals. DRW did
not assume any obligation to conduct, and did not conduct, any physical
inspection of the property or facilities of Broadbase or Servicesoft. DRW
assumed that the business combination will be treated as a purchase under
generally accepted accounting principles and as a reorganization for U.S.
federal income tax purposes. DRW's opinion is based on the economic, market and
other conditions as they existed and the information supplied to DRW as of the
date of its opinion. Events occurring after the date of DRW's opinion may
materially affect the assumptions used in preparing the opinion, and DRW assumes
no obligation to update, revise or reaffirm its opinion.

     In arriving at its opinion, DRW:

     - reviewed and analyzed the financial terms of the merger agreement;

     - reviewed and analyzed publicly available financial and other data with
       respect to Broadbase and Servicesoft and certain other historical
       operating data relating to Broadbase and Servicesoft made available to it
       from published sources and from the internal records of the companies;

     - conducted discussions with members of the senior management of
       Servicesoft with respect to the business prospects and financial outlook
       of Servicesoft;

     - conducted discussions with members of the senior management of Broadbase
       with respect to the business prospects and financial outlook of Broadbase
       and the combined entity;

     - received and reviewed financial forecasts prepared by Servicesoft's
       management and Broadbase's management relating to the potential future
       performance of Servicesoft, both as a stand alone entity and as a part of
       Broadbase;

     - reviewed certain projections of Broadbase's financial results, compiled
       from publicly-available research;

     - analyzed the impact of the merger on Broadbase's earnings per share;

     - reviewed the reported prices and trading activity for Broadbase common
       stock;

     - compared the financial performance of Broadbase and Servicesoft and the
       implied valuation of Servicesoft with that of certain other comparable
       publicly-traded companies and their securities;

     - reviewed the financial terms, to the extent publicly available, of
       certain comparable merger transactions; and

     - compared the relative contribution to certain income statement items of
       each company with their pro-forma ownership in the combined company.

     In addition, DRW has conducted such other analyses and examinations and
considered such other financial, economic and market criteria as DRW deemed
necessary in arriving at its opinion.

     The following is a summary of the financial analyses performed and other
information deemed material by DRW in connection with the delivery of its
opinion but is not a comprehensive description of all analyses performed or
factors considered. These summaries of financial analyses include information
presented in tabular format. In order to fully understand the summary of the
financial analyses used by DRW, the tables must be read together with the text
of each summary. The tables alone do not constitute a complete description of
the financial analysis.

     Comparable Company Analysis.  DRW used a comparable company analysis to
analyze Servicesoft's implied valuation relative to a group of publicly traded
companies that DRW deemed for purposes of its analysis to be comparable to
Servicesoft. In this analysis, DRW compared the enterprise value of Servicesoft
implied by the exchange ratio based on the trading price of Broadbase's common
stock at closing on September 15, 2000, expressed as a multiple of actual and
projected revenue in calendar years 1999, 2000, and 2001, to the range, mean and
median multiples of enterprise values of comparable companies implied by the
public trading price of their common stock, expressed as a multiple of the same

                                       59
<PAGE>   67

operating data. Enterprise value is defined as market capitalization, or equity
value, plus debt less cash and cash equivalents. Multiples of future revenue for
Servicesoft were based on projected revenue as estimated by Broadbase's
management and, for the comparable companies, on publicly available estimates.
The analysis was limited to revenue multiples due to the lack of profitability
of Servicesoft and the comparable companies through calendar year 2001. DRW
compared enterprise value to revenue multiples of Servicesoft with those of the
following publicly traded companies: AskJeeves, Inc., Chordiant Software, Inc.,
eGain Communications Corp., E.piphany, Inc., Kana Communications, Inc., Primus
Knowledge Solutions, Inc., Quintus Corporation, and Serviceware Technologies,
Inc. Although these companies were considered comparable to Servicesoft for the
purpose of this analysis based on certain characteristics of their respective
businesses and financial performance, none of these companies possesses
characteristics identical to those of Servicesoft.

     The following table presents, as of September 15, 2000, Servicesoft's
implied enterprise value to revenue multiples and the range, mean and median
enterprise value to revenue multiples for the aforementioned comparable
companies in the calendar years 1999, 2000 and 2001:

     Precedent Transaction Analysis.  DRW compared transaction value to revenue
multiples relating to the proposed combination of Servicesoft and Broadbase with
transaction value to revenue multiples paid in selected business combination and
acquisition transactions since September 1, 1999 for companies that compete in
the electronic Customer Relations Management market, or eCRM market. For the
purpose of calculating multiples, revenue values were taken as the actual or
estimated revenue of the target companies in the last twelve months prior to the
announcement of the transaction, or LTM revenue. Financial data regarding the
precedent transactions was taken from SEC filings, press releases and DRW
estimates.

     DRW noted that many of these transactions involved target companies that
were small and whose transaction value to revenue multiples were therefore not
comparable to that of Servicesoft. To account for this, DRW excluded from its
calculations of low, high, mean and median those transactions where the target
company had LTM revenues of less that $1 million. DRW also noted that public
company valuations in the eCRM market have changed materially since the
beginning of the year. As such, DRW analyzed the precedent transactions both in
terms of the implied transaction value at announcement and an adjusted
transaction value which takes into account the changes in stock prices of the
acquirers since announcement. In addition to analyzing the low, high, mean and
median of values for the 25 transactions, DRW selected six transactions that it
deemed most comparable to this transaction based on the financial and business
characteristics of the target companies in those transactions. The selected
transactions were:

     - the acquisition of DataSage Inc. by Vignette Corporation, announced on
       January 10, 2000;

     - the acquisition of Silknet Software Inc. by Kana Communications, Inc.,
       announced on February 6, 2000;

     - the acquisition of Octane Software Inc. by E.piphany, Inc., announced on
       March 14, 2000;

     - the acquisition of Inference Corp. by eGain Communications Corp.,
       announced on March 16, 2000;

     - the acquisition of OnDisplay, Inc. by Vignette Corporation, announced on
       May 21, 2000; and

     - the acquisition of OnLink Technologies, Inc. by Siebel Systems, Inc.,
       announced on August 7, 2000.

     Relative Contribution Analysis.  DRW analyzed the relative contribution of
each of Broadbase and Servicesoft in calendar years 1999, 2000 and 2001 in terms
of various financial statement categories relative to the pro forma combined
financial statements where the two stand-alone companies were combined assuming
no synergies. Due to lack of profitability, the financial statement categories
included revenue and gross profit. DRW compared the relative contributions to
the pro forma ownership percentage of Broadbase and Servicesoft security holders
in the pro forma post-business combination combined company based on the
fully-diluted equity ownership of the combined entity. DRW observed that, based
upon the exchange ratio set forth in the merger agreement, the relative
ownership of the combined company by Servicesoft and Broadbase security holders,
on a fully-diluted basis, would be 34.3% and 65.7%, respectively, at the close
of the business combination. DRW also noted that the implied Servicesoft and
Broadbase pro forma ownership, on an enterprise value basis, would be 38.3% and
61.7%, respectively. The following is a summary of this analysis:

     Merger Analysis. DRW analyzed the pro forma impact of the transaction on
the projected earnings per share of the combined company for fiscal 2001 using
Broadbase management estimates. DRW noted that an analysis of earnings excluding
the impact of goodwill amortization was most relevant for examining the
financial impact of the transaction. Excluding goodwill amortization and
one-time transaction-related costs, DRW estimated that the impact of the
transaction on the combined company's earnings per share would be neutral by the
fourth quarter of fiscal 2001. DRW also noted that the analysis indicated the
merger should not delay Broadbase's objective to reach profitability in the
second half of fiscal 2001.

     The preparation of a fairness opinion is a complex process that involves
the application of subjective business judgment in determining the most
appropriate and relevant methods of financial analysis and the application of
those methods to the particular circumstances and, therefore, is not necessarily
susceptible to partial consideration of the analyses or summary description. DRW
believes that its analyses must be considered as a whole and that selecting
portions of the analyses and of the factors considered by it, without
considering all factors and analyses, could create an incomplete or misleading
view of the processes underlying its opinion. In arriving at its fairness
determination, DRW considered the results of all of its analyses as well as
qualitative factors, including the enhanced competitive position of the combined
company from a broader suite of products, the management team of Servicesoft,
and the greater size and critical mass of the combined company. In view of the
wide variety of factors considered in connection with its evaluation of the
fairness of the merger consideration to Broadbase from a financial point of
view, DRW did not find it practicable to assign relative weights to the factors
considered in reaching its opinion. No single company or transaction used in the
above analyses as a comparison is identical to Broadbase or Servicesoft or the
proposed business combination. The analyses were prepared solely for purposes of
DRW providing an opinion as to the fairness to Broadbase and its stockholders of

                                       61
<PAGE>   69

the business combination consideration and do not purport to be appraisals or
necessarily reflect the prices at which businesses or securities actually may be
sold, which are inherently subject to uncertainty. In connection with its
analyses, DRW made, and was provided by Broadbase's management with, numerous
assumptions with respect to industry performance, general business and economic
conditions and other matters, many of which are beyond Broadbase's or
Servicesoft's control. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than suggested by such analyses. Because such analyses are
inherently subject to uncertainty, being based upon numerous factors or events
beyond the control of Broadbase, Servicesoft or their advisors, none of
Broadbase, DRW or any other person assumes responsibility if future results or
actual values are materially different from these forecasts or assumptions. DRW
was not provided with long-term projections for Servicesoft and, thus, DRW did
not prepare a discounted cash flow analysis for purposes of its opinion.

     DRW is a nationally recognized investment banking firm and is regularly
engaged in the valuation of businesses and securities in connection with
business combinations and acquisitions, corporate restructurings, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. DRW
regularly publishes research reports regarding the eCRM industry and the
businesses and securities of publicly owned companies in that industry. In the
ordinary course of business, DRW and its affiliates may actively trade
securities of Broadbase for their own account or the account of their customers
and, accordingly, may from time to time hold a long or short position in those
securities. Broadbase selected DRW to render its opinion based on DRW's
knowledge of the technology industry and its experience in business combinations
and acquisitions and in securities valuation generally.

     Pursuant to an engagement letter, Broadbase paid DRW a nonrefundable fee of
$500,000 upon the rendering of its opinion. Payment of this fee to DRW was not
contingent upon the closing of the business combination. Broadbase has agreed to
pay DRW an additional transaction fee of $2,000,000 for investment banking and
financial advisory services. The transaction fee is contingent upon the closing
of the business combination before September 7, 2001. Whether or not the
transaction closes Broadbase has agreed to reimburse DRW for its reasonable
out-of-pocket expenses and to indemnify DRW against liabilities incurred. These
include liabilities under the federal securities laws in connection with the
engagement of DRW by Broadbase's board of directors. The terms of the engagement
letter, which Broadbase believes are customary for transactions of this nature,
were negotiated at arms'-length between Broadbase and DRW, and the Broadbase
board of directors was aware of this fee arrangement at the time of its approval
of the merger agreement.

OPINION OF SERVICESOFT'S FINANCIAL ADVISOR

     Under an engagement letter dated September 1, 2000, Servicesoft retained
Morgan Stanley to provide it with certain financial advisory services in
connection with the merger. Morgan Stanley was selected by Servicesoft based on
Morgan Stanley's qualifications, expertise, reputation and its knowledge of the
business and affairs of Servicesoft. At the meeting of Servicesoft's Board on
September 15, 2000, Morgan Stanley rendered its oral opinion, subsequently
confirmed in writing, that as of September 15, 2000, based upon and subject to
the various considerations set forth in the opinion, the exchange ratio pursuant
to the merger agreement was fair from a financial point of view to holders of
shares of Servicesoft common stock.

MEETING. THE SUMMARY OF THE OPINION OF MORGAN STANLEY SET FORTH IN THIS DOCUMENT
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF ITS OPINION.

     Broadbase retained Morgan Stanley as its financial advisor, and Servicesoft
retained Morgan Stanley to provide it with a fairness opinion, each with the
consent of the other party. Morgan Stanley will receive customary fees for such
services. Broadbase and Servicesoft also consented to the use of separate teams
by Morgan Stanley to represent each of them and to share information regarding
each company. Broadbase was aware, before engaging Morgan Stanley, that Morgan
Stanley owned a pre-existing 0.55% equity interest in Servicesoft. The decision
to retain Morgan Stanley was based on its reputation, its extensive knowledge of
each company's business and its past relationships with each company. Morgan
Stanley did not participate in the negotiation of the exchange ratio. The
exchange ratio was negotiated through arm's length negotiations between
Broadbase and Servicesoft and was approved by each company's board of directors.

     In rendering its opinion, Morgan Stanley, among other things:

     - reviewed certain publicly-available financial statements and other
       information of Servicesoft and Broadbase;

     - reviewed certain internal financial statements and other financial and
       operating data concerning Servicesoft and Broadbase prepared by the
       managements of Servicesoft and Broadbase, respectively;

     - discussed certain financial projections of Servicesoft and Broadbase
       prepared by the managements of Servicesoft and Broadbase, respectively;

     - discussed the past and current operations and financial condition and the
       prospects of Servicesoft and Broadbase, including information relating to
       certain strategic, financial and operational benefits anticipated from
       the merger, with senior executives of Servicesoft and Broadbase,
       respectively;

     - reviewed the reported prices and trading activity for Broadbase common
       stock;

     - compared the financial performance of Servicesoft and Broadbase and the
       prices and trading activity of Broadbase common stock with that of
       certain other comparable publicly-traded companies and their securities;

     - reviewed the financial terms, to the extent publicly available, of
       certain comparable acquisition transactions;

     - reviewed the merger agreement and certain related documents; and

     - considered such other factors and analyses as it deemed appropriate.

     Morgan Stanley assumed and relied upon, without independent verification,
the accuracy and completeness of the information reviewed by it for the purposes
of its opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from the merger, Morgan Stanley assumed that they were reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance and prospects of Broadbase and Servicesoft. Morgan
Stanley relied upon the assessment by the managements of Broadbase and
Servicesoft of their ability to retain key employees of Servicesoft and
Broadbase. Morgan Stanley also relied upon, without independent verification,
the assessment by the management of Servicesoft of Broadbase's technologies and
products, the timing and risks associated with the integration of Servicesoft
with Broadbase and the validity of, and risks associated with, Servicesoft's
existing and future products and technologies.

     In addition, Morgan Stanley assumed that the merger will be consummated in
accordance with the terms set forth in the merger agreement, including, among
other things, that the merger will be treated as a tax-free reorganization
and/or exchange pursuant to the Internal Revenue Code. Morgan Stanley did not
make any independent valuation or appraisal of the assets or liabilities of
Servicesoft or Broadbase, nor was it furnished with any such appraisals. Morgan
Stanley's opinion was necessarily based on financial, economic, market and other
conditions as in effect on, and the information made available to it as of, the
date of its opinion.

                                       63
<PAGE>   71

     In arriving at its opinion, Morgan Stanley was not authorized to solicit,
and did not solicit interest from any party with respect to the acquisition of
Broadbase.

     The following is a brief summary of certain analyses performed by Morgan
Stanley in connection with its opinion dated September 15, 2000. In the
following analyses, Morgan Stanley used publicly-available research analyst
estimates with respect to Broadbase's projected results of operations. These
summaries of financial analyses include information presented in tabular format.
In order to fully understand the financial analyses used by Morgan Stanley, the
tables must be read together with the text of each summary. The tables alone do
not constitute a complete description of the financial analyses.

     Contribution Analysis.  Morgan Stanley analyzed the relative contribution
of Servicesoft and Broadbase to historical and estimated revenues and gross
profit of the combined company for calendar years 2000 to 2001 based on
estimates published by securities research analysts for Broadbase and estimates
developed by Morgan Stanley for Servicesoft. Morgan Stanley's contribution
analysis assumed no synergies. The following table presents the results of that
analysis:

     Morgan Stanley noted that the pro forma ownership of the combined company

merger agreement would be 36.5% based on the treasury method of calculating
shares outstanding for Broadbase and Servicesoft.

     Comparable Company Analysis.  Morgan Stanley compared selected financial
information for Broadbase with publicly available information for comparable
software companies, including Kana Communications, Inc., E.piphany, Inc., Accrue
Software, Inc., Pivotal Corporation, Firepond, Inc., Net Perceptions, Inc.,
eGain Communications Corporation, Quintus Corporation, Calico Commerce, Inc. and
Prime Response, Inc. Based upon calendar year 2001 projected revenue estimates
published by securities research analysts and using the closing prices as of
September 13, 2000, Morgan Stanley calculated, for

                                       64

each of these companies, the multiple of aggregate value to projected calendar

</TABLE>

     Morgan Stanley noted that the multiple of aggregate value to projected
calendar year 2001 revenue estimates implied by the exchange ratio set forth in
the merger agreement would be 13.7x.

     No company included in the comparable company analyses is identical to
Servicesoft or Broadbase. In evaluating the comparable companies, Morgan Stanley
made judgments and assumptions with regard to industry performance, general
business, economic, market and financial conditions and other matters. Many of
these matters are beyond the control of Servicesoft or Broadbase, such as the
impact of competition on the business of Servicesoft or Broadbase and the
industry in general, industry growth and the absence of any material adverse
change in the financial condition and prospects of Servicesoft or Broadbase or
the industry or in the financial markets in general. Mathematical analysis, such
as determining the average or median, is not in itself a meaningful method of
using comparable company data.

     Initial Pubic Offering Valuation Analysis.  Morgan Stanley analyzed
selected financial information for Servicesoft and compared such information
with publicly available information for comparable software companies to
establish a preliminary filing range for Servicesoft's initial public offering.
Morgan Stanley reviewed the forward revenue multiples of selected comparable
companies, as well as software companies that had recently completed their
initial public offerings, at three points in time:

     - upon initial filing of their registration statements;

     - upon pricing of their initial public offerings; and

     - just prior to filing Servicesoft's preliminary registration statement
       with the Securities and Exchange Commission.

     Forward revenue multiples were calculated using research analyst estimates
then available. Morgan Stanley reviewed the forward revenue multiples for the
following software companies:

     - Art Technology Group

     - E.piphany, Inc.

     - eGain Communications Corporation

     - Interwoven, Inc.

     - Kana Communications, Inc.

     - Silknet Software, Inc.

     - webMethods, Inc.

                                       65
<PAGE>   73

     Morgan Stanley noted that the capitalization for Servicesoft implied by the
preliminary IPO analysis would range between $375 million and $425 million.

     No company included in the IPO analyses is identical to Servicesoft. In
evaluating the comparable companies, Morgan Stanley made judgments and
assumptions with regard to industry performance, general business, economic,
market and financial conditions and other matters. Many of these matters are
beyond the control of Servicesoft, such as the impact of competition on the
business of Servicesoft and the industry in general, industry growth and the
absence of any material adverse change in the financial condition and prospects
of Servicesoft or the industry or in the financial markets in general.

     Precedent Transaction Analysis.  Morgan Stanley compared certain
publicly-available statistics for selected transactions in the software sector
from January 26, 2000 to May 22, 2000. Morgan Stanley estimated the multiple of
the acquired company's next twelve months' revenue, based on projected revenue
estimates published by securities research analysts, at the time of announcement
of the transaction, implied by the transaction value for each of the following
transactions:

     - OnDisplay/Vignette

     - Active Software/webMethods

     - Spyglass/OpenTV

     - Silknet Software/Kana Communications

     - INTERVU/Akamai Technologies

     - Interleaf/BroadVision

     Morgan Stanley then compared this multiple to the next twelve months
revenue multiple of the acquiring company, based on projected revenue estimates
published by securities research analysts, for each of the above transactions.
The following table presents the indicated next twelve months revenue multiple
for the acquired company and the percentage that this number represents of the
acquirer's next twelve months revenue multiple in each instance:

</TABLE>

     Morgan Stanley noted that the next twelve months revenue multiple for
Servicesoft implied by the exchange ratio set forth in the merger agreement
would be 16.1x, which reflects 142.5% of the Broadbase next twelve months
revenue multiple.

     No transaction included in the precedent transaction analyses is identical
to the merger. In evaluating the precedent transactions, Morgan Stanley made
judgments and assumptions with regard to industry performance, general business,
economic, market and financial conditions and other matters. Many of these
matters are beyond the control of Servicesoft or Broadbase, such as the impact
of competition on the business of Servicesoft or Broadbase and the industry in
general, industry growth and the absence of any material adverse change in the
financial condition and prospects of Servicesoft or Broadbase or the industry or
in the financial markets in general. Mathematical analysis, such as determining
the average or median, is not in itself a meaningful method of using precedent
transaction data.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. In
arriving at its opinion, Morgan Stanley considered the results of

                                       66
<PAGE>   74

all of its analyses as a whole and did not attribute any particular weight to
any particular analysis or factor considered by it. Furthermore, Morgan Stanley
believes that the summary provided and the analysis described above must be
considered as a whole and that selecting any portion of Morgan Stanley's
analyses, without considering all its analyses, would create an incomplete view
of the process underlying Morgan Stanley's opinion. In addition, Morgan Stanley
may have deemed various assumptions more or less probable than other
assumptions, so that the range of valuations resulting from any particular
analysis described above should not be taken to be Morgan Stanley's view of the
actual value of Servicesoft or Broadbase.

     In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Servicesoft or Broadbase.
Any estimates contained in Morgan Stanley's analysis are not necessarily
indicative of future results or actual values, which may be significantly more
or less favorable than those suggested by such estimates. The analyses performed
were prepared solely as part of Morgan Stanley's analysis of the fairness of the
exchange ratio pursuant to the merger agreement from a financial point of view
to Servicesoft and were conducted in connection with the delivery of the Morgan
Stanley opinion to the board of directors of Servicesoft. The analyses do not
purport to be appraisals or to reflect the prices at which Servicesoft common
stock or Broadbase common stock might actually trade. The exchange ratio
pursuant to the merger agreement and other terms of the merger agreement were
determined through arm's length negotiations between Servicesoft and Broadbase
and were approved by the Servicesoft board of directors. Morgan Stanley provided
advice to Servicesoft during such negotiations; however, Morgan Stanley did not
recommend any specific consideration to Servicesoft or that any specific
consideration constituted the only appropriate consideration for the merger. In
addition, as described above, Morgan Stanley's opinion and presentation to the
Servicesoft board of directors was one of many factors taken into consideration
by Servicesoft's board of directors in making its decision to approve the
merger. Consequently, the Morgan Stanley analyses as described above should not
be viewed as determinative of the opinion of the Servicesoft board of directors
with respect to the value of Servicesoft or of whether the Servicesoft board of
directors would have been willing to agree to a different consideration.

     The Servicesoft board of directors retained Morgan Stanley based upon
Morgan Stanley's qualifications, experience and expertise. Morgan Stanley is an
internationally recognized investment banking and advisory firm. Morgan Stanley,
as part of its investment banking and financial advisory business, is
continuously engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwriting, competitive bidding,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. With Servicesoft's consent,
Morgan Stanley acted as a financial advisor to Broadbase in connection with the
merger and will receive a fee in connection with the merger. In the ordinary
course of Morgan Stanley's trading and brokerage activities, Morgan Stanley or
its affiliates may at any time hold long or short positions, trade or otherwise
effect transactions, for its own account or for the account of customers, in the
equity or debt securities or senior loans of Broadbase.

     Pursuant to an engagement letter dated September 1, 2000, Morgan Stanley
provided Servicesoft advisory services and a financial opinion in connection
with the merger, and Servicesoft agreed to pay Morgan Stanley a customary fee
for its services. Servicesoft has also agreed to reimburse Morgan Stanley for
its expenses incurred in performing its services. In addition, Servicesoft has
agreed to indemnify Morgan Stanley and its affiliates, their respective
directors, officers, agents and employees and each person, if any, controlling
Morgan Stanley or any of its affiliates against certain liabilities and
expenses, including certain liabilities under the federal securities laws,
related to or arising out of Morgan Stanley's engagement and any related
transactions. In the past, Morgan Stanley and its affiliates have provided
financial advisory services for Servicesoft and have received fees for the
rendering of these services.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS IN THE MERGER

     The executive officers and directors of Broadbase and Servicesoft have
interests in the merger that are different from, or are in addition to, those of
Broadbase and Servicesoft stockholders generally. These interests include the
following:

     - Massood Zarrabian, the Chief Executive Officer and President of
       Servicesoft, and Robert E. Davoli, a director of Servicesoft, will become
       members of Broadbase's board of directors after the merger;

     - Mr. Zarrabian, Daniel J. Kossmann, Paul R. Maguire and Alf Saggesse, each
       an executive officer of Servicesoft, have employment agreements with
       Broadbase that provide for benefits upon completion of the merger,
       including severance and other payments and acceleration of restricted
       stock and stock option vesting;

     - Executive officers of Servicesoft may become officers of Broadbase after
       the merger;

     - Many executive officers and directors of Servicesoft hold substantial
       interests, in the form of Servicesoft shares or stock options, that will
       be exchanged for Broadbase shares or options in the merger;

     - Several executive officers and directors of Servicesoft have agreements
       that provide for benefits, including severance and other payments and
       acceleration of stock option vesting, that may be triggered upon the
       closing of the merger or termination of employment after the closing of
       the merger; and

     - Executive officers and directors of both Broadbase and Servicesoft have
       customary rights to indemnification against specified liabilities.

     As a result, these executive officers and directors could be more likely to
vote in favor of and to recommend the approval of the merger than if they did
not hold these interests.

COMPLETION AND EFFECTIVENESS OF THE MERGER

     The merger will be completed when all of the conditions to completion of
the merger are satisfied or waived, including approval and adoption of the
merger agreement, approval of the merger by the stockholders of Servicesoft,
approval of the issuance of shares of Broadbase common stock in the merger and
approval of the amendment to Broadbase's certificate of incorporation by
Broadbase's stockholders. The merger will become effective upon the filing of a
certificate of merger with the State of Delaware.

STRUCTURE OF THE MERGER

     Soldier Acquisition Corp., a newly-formed and wholly-owned subsidiary of
Broadbase, will be merged with and into Servicesoft. As a result of the merger,
the separate corporate existence of Soldier Acquisition Corp. will cease and
Servicesoft will survive the merger as a wholly-owned subsidiary of Broadbase.

TREATMENT OF SERVICESOFT COMMON STOCK, PREFERRED STOCK, OPTIONS AND WARRANTS

  Treatment of Servicesoft common stock and preferred stock

     At the closing, each outstanding share of Servicesoft common stock will be
converted into the right to receive 1.4404 shares of Broadbase common stock,
except for any shares with respect to which appraisal rights are exercised and
for the outstanding shares of Servicesoft Series X and Series Y preferred stock.
The single share of Series X preferred stock and the single share of Series Y
preferred stock will each be redeemed by Servicesoft for $1.00 prior to the
completion of the merger. The number of shares of Broadbase common stock
issuable in the merger will be proportionately adjusted for any stock split,
stock dividend or similar event with respect to Broadbase common stock or
Servicesoft common stock effected between the date of the merger agreement and
the completion of the merger.

     To the extent any shares of Servicesoft stock that are outstanding
immediately prior to the closing of the merger are unvested or are subject to a
right of repurchase by Servicesoft upon termination of the

                                       68
<PAGE>   76

stockholder's relationship with Servicesoft, then the shares of Broadbase common
stock issued in the merger will continue to be unvested and subject to the same
repurchase options, risks of forfeiture or other conditions.

     Servicesoft is required under the merger agreement to cause holders of its
preferred stock to convert their preferred stock into common stock before the
closing of the merger, with the exception of holders of of its single shares of
Series X preferred stock and Series Y preferred stock, which will each be
redeemed for $1.00 before the closing in accordance with their terms.
Servicesoft will solicit the consent of holders of its preferred stock to the
conversion of their shares separately from this document and from the
Servicesoft stockholder meeting. Each share of Servicesoft preferred stock is
convertible into one share of Servicesoft common stock. If shares of preferred
stock remain outstanding and Broadbase agrees to waive the condition that they
be converted, they will also be converted by virtue of the merger into Broadbase
common stock at the exchange ratio of 1.4404.

     Servicesoft's subsidiary, Servicesoft Canada, has issued and outstanding
shares of stock that are exchangeable on a one-for-one basis for shares of
Servicesoft's Series H preferred stock (Servicesoft Canada exchangeable
preferred stock) and for Servicesoft common stock (Servicesoft Canada
exchangeable common stock). The stockholders of Servicesoft Canada received
these exchangeable shares in connection with the acquisition by Servicesoft of
Servicesoft Canada, formerly Balisoft Technologies Inc., in February 1999.

     Servicesoft is required by the terms of the merger agreement to cause
holders of Servicesoft Canada's exchangeable preferred stock and exchangeable
common stock to exchange that stock for the corresponding Servicesoft stock
before the closing of the merger. To that end, Servicesoft Canada will hold a
special meeting of its holders of exchangeable common stock prior to the
Servicesoft stockholders' meeting to obtain the necessary approvals for this
exchange. Servicesoft Canada will request a similar approval from the holders of
exchangeable preferred stock by way of a written stockholders' resolution. This
exchange will require the approval of stockholders representing at least
two-thirds of the total votes cast at the meeting, or by written consent, as
applicable, and the approval will also require that the holders of at least 50%
of the then-outstanding exchangeable shares be present in person or represented
by proxy at the meeting, as applicable.

     No certificate or scrip representing fractional shares of Broadbase common
stock will be issued in connection with the merger. Instead, Servicesoft
stockholders will receive cash, without interest, in lieu of a fraction of a
share of Broadbase common stock.

  Treatment of Servicesoft's options and warrants

     Upon completion of the merger, each outstanding Servicesoft stock option or
warrant will be converted into an option or warrant to purchase shares of
Broadbase common stock. The number of shares subject to each new Broadbase stock
option or warrant will be equal to 1.4404, multiplied by the number of shares
subject to the Servicesoft stock option or warrant, rounded down to the nearest
whole share. The exercise price per share for each new Broadbase stock option
and warrant will be equal to the exercise price per share of the Servicesoft
stock option or warrant, divided by 1.4404, rounded up to the nearest whole
cent. The other terms of Servicesoft's warrants and options and, with respect to
options, the existing Servicesoft option plans under which Servicesoft issued
the options, will continue to apply to the converted warrants and options,
including any provisions providing for vesting.

     In connection with the merger, Broadbase has also agreed to assume
Servicesoft's Employee Stock Purchase Plan. Servicesoft is currently obligated
to issue approximately 64,515 shares of Servicesoft common stock under this
plan, which will each be converted into the right to receive shares of Broadbase
common stock at the conversion rate of 1.4404. Servicesoft's board of directors
has suspended offers of Servicesoft stock under the plan.

     Under the merger agreement, Broadbase is required to file a registration
statement on Form S-8 within 15 days after the closing of the merger for the
shares of Broadbase common stock issuable with respect to options outstanding
under the Servicesoft stock option plans and shares issuable under the
Servicesoft Employee Stock Purchase Plan. Broadbase has agreed to use reasonable
efforts to maintain the effectiveness of that registration statement for as long
as any of the options or shares remain outstanding.
                                       69
<PAGE>   77

ESCROW ARRANGEMENT

     A total of 10% of the shares of Broadbase common stock issued in the merger
in exchange for outstanding shares of Servicesoft stock will be deposited in an
escrow account to be administered by State Street Bank and Trust Company of
California, the escrow agent. By approving the merger agreement, the Servicesoft
stockholders will authorize the creation of the escrow account, the terms of the
escrow agreement and the appointment of Mark S. Skapinker, the current Chairman
of the Board of Directors of Servicesoft, as their agent with respect to
indemnification matters. The purpose of the escrow account is to provide a
source of indemnification for Broadbase and its representatives in the event
that they suffer damages as a result of a breach of Servicesoft's
representations, warranties and covenants in the merger agreement and a source
of the recovery of fees and expenses, other than investment bankers' fees,
incurred by Servicesoft in connection with the merger in excess of $500,000.

     The escrow fund will serve as Broadbase's exclusive remedy for damages for
which Broadbase is entitled to indemnification under the merger agreement, other
than with respect to claims of intentional fraud or relating to ownership of the
Servicesoft stock exchanged in the merger. Please refer to the section entitled
"The Merger Agreement -- Indemnification obligations of Servicesoft's
stockholders" on page 86 for further detail about the indemnification
obligations of Servicesoft's stockholders.

EXCHANGE OF SERVICESOFT STOCK CERTIFICATES FOR BROADBASE STOCK CERTIFICATES

     When the merger is completed, Broadbase's exchange agent will mail to
Servicesoft stockholders a letter of transmittal and instructions for use in
surrendering Servicesoft stock certificates in exchange for Broadbase stock
certificates, together with other documents for execution by the stockholders as
required by the merger agreement.

     When a Servicesoft stockholder delivers its Servicesoft stock certificates
to the exchange agent along with

     - an executed letter of transmittal,

     - an executed letter agreement indicating the stockholder's agreement to
       indemnify Broadbase and its representatives in accordance with the
       indemnification provisions of the merger agreement and making
       representations and warranties relating to the stockholder's ownership of
       its Servicesoft stock, and

     - with respect to executive officers, directors and other affiliated
       stockholders of Servicesoft, an executed agreement not to sell any of the
       shares of Broadbase common stock received in the merger for a period of
       90 days,

the Servicesoft stock certificates will be canceled and the stockholder will
receive Broadbase stock certificates representing the number of full shares of
Broadbase common stock to which it is entitled under the merger agreement,
subject to the escrow arrangement described above.

     Servicesoft stockholders will receive payment in cash, without interest,
instead of any fractional shares of Broadbase common stock that would otherwise
be issued to them in the merger. Stockholders should not submit their
Servicesoft stock certificates for exchange unless and until they receive the
transmittal instructions and a form of letter of transmittal from the exchange
agent.

     Generally, after the closing of the merger, an unexchanged Servicesoft
stock certificate is deemed to evidence, for all purposes, the applicable number
of shares of Broadbase common stock issued in the merger with respect to the
Servicesoft stock represented by that certificate, except that a Servicesoft
stockholder will not be entitled receive any dividends or other distributions on
Broadbase common stock until the stockholder has surrendered its Servicesoft
stock certificates in exchange for Broadbase stock certificates.

     Broadbase will only issue Servicesoft stockholders a Broadbase stock
certificate or a check instead of a fractional share in a name in which the
surrendered Servicesoft stock certificate is registered. If any

                                       70
<PAGE>   78

Servicesoft stockholder wishes to have a certificate or check issued in another
name, such stockholder must present the exchange agent with all documents
required to show and effect the unrecorded transfer of ownership and show that
it paid any applicable stock transfer taxes. If any Servicesoft stockholder has
lost its Servicesoft stock certificate, that stockholder will be required to
furnish an affidavit of loss and a bond in addition to the documents
accompanying the letter of transmittal to receive the corresponding Broadbase
stock certificate.

SERVICESOFT STOCKHOLDERS' APPRAISAL RIGHTS

     Even if the merger is approved by Servicesoft's stockholders, any
Servicesoft stockholders who do not vote in favor of or consent to the merger
can take steps to exercise rights of appraisal under Delaware law, rather than
receiving the shares of Broadbase stock in the merger. Generally, under Section
262 of the Delaware General Corporation Law, a stockholder who, among other
things

     - holds shares of Servicesoft's stock on the date that it makes a demand in
       accordance with Section 262 with respect to those shares,

     - continuously holds those shares through the effective time of the merger,
       and

     - has not voted in favor of the merger or consented to the merger,

will be entitled to an appraisal by the Delaware Court of Chancery of the fair
value of the stockholder's shares of stock, exclusive of any element of value
arising from the accomplishment or expectation of the merger or consolidation,
together with a fair rate of interest, if any, to be paid upon the amount
determined to be the fair value. The surviving corporation in the merger will
then be required to pay the stockholder the fair value determined by the court.
A stockholder who wishes to exercise appraisal rights must deliver a written
demand for appraisal to Servicesoft before the vote of Servicesoft's
stockholders is completed. Broadbase's stockholders are not entitled to
dissenters' rights or appraisal rights with respect to the merger.

     The provisions of Delaware law governing appraisal rights are complex, and
you should study them carefully if you wish to exercise appraisal rights;
certain courses of conduct by a stockholder can prevent that stockholder from
successfully asserting these rights, and there are multiple steps involved to
properly perfect the rights. See "Appraisal Rights" on page 145 for more detail.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The following discussion summarizes the material United States federal
income tax consequences of the merger. This discussion is based on the Internal
Revenue Code, the related regulations, existing administrative interpretations
and court decisions, all of which are subject to change, possibly with
retroactive effect. This discussion assumes that Servicesoft stockholders hold
their shares of Servicesoft common stock as capital assets within the meaning of
Section 1221 of the Internal Revenue Code. This discussion does not address all
aspects of United States federal income taxation that may be important to you in
light of your particular circumstances or if you are subject to special rules.
These special rules include rules relating to:

     - stockholders who are not citizens or residents of the United States;

     - financial institutions;

     - tax-exempt organizations;

     - insurance companies;

     - dealers in securities;

     - stockholders who acquired their shares of Servicesoft common stock
       through the exercise of options or similar derivative securities or
       otherwise as compensation; or

     - stockholders who hold their shares of Servicesoft common stock as part of
       a straddle, conversion or other integrated transaction.
                                       71
<PAGE>   79

     We believe, based on the advice of our respective counsel, that the merger
will have the United States federal income tax consequences discussed below. The
advice of our counsel referred to above assumes the absence of changes in
existing facts and relies on assumptions, representations and covenants by the
parties to the merger. No assurance can be given that contrary positions will
not be successfully asserted by the IRS or adopted by a court if the positions
were litigated. Neither of us intends to obtain a ruling from the IRS with
respect to the tax consequences of the merger.

  Tax consequences to Broadbase stockholders.

     Current stockholders of Broadbase will not recognize gain or loss for
United States federal income tax purposes as a result of the merger.

  Tax consequences to Servicesoft stockholders.

     Except as discussed below, current stockholders of Servicesoft will not
recognize gain or loss for United States federal income tax purposes on the
exchange of Servicesoft common stock for Broadbase common stock in the merger.
The aggregate tax basis of the Broadbase common stock received as a result of
the merger will be the same as the aggregate tax basis in the Servicesoft common
stock surrendered in the exchange, reduced by the tax basis of any shares of
Servicesoft common stock for which cash is received instead of fractional shares
of Broadbase common stock. The holding period of the Broadbase common stock
received as a result of the exchange will include the period during which the
Servicesoft common stock exchanged in the merger was held.

     Servicesoft stockholders will recognize gain or loss for United States
federal income tax purposes with respect to the cash they receive instead of a
fractional share interest in Broadbase common stock. The gain or loss will be
measured by the difference between the amount of cash they receive and the
portion of the tax basis of their shares of Servicesoft common stock allocable
to the shares of Servicesoft common stock exchanged for the fractional share
interest. This gain or loss will be capital gain or loss and will be a long-
term capital gain or loss if the shares of Servicesoft common stock have been
held for more than one year at the time the merger is completed.

  Tax consequences to Broadbase and Servicesoft.

     Broadbase, including its merger subsidiary, and Servicesoft will not
recognize gain or loss for United States federal income tax purposes as a result
of the merger.

     THIS DISCUSSION IS ONLY INTENDED TO PROVIDE YOU WITH A GENERAL SUMMARY, AND
IT IS NOT INTENDED TO BE A COMPLETE ANALYSIS OR DESCRIPTION OF ALL POTENTIAL
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER. IN ADDITION, THIS
DISCUSSION DOES NOT ADDRESS TAX CONSEQUENCES THAT MAY VARY WITH, OR ARE
CONTINGENT ON, YOUR INDIVIDUAL CIRCUMSTANCES. MOREOVER, THIS DISCUSSION DOES NOT
ADDRESS ANY NON-INCOME TAX OR ANY FOREIGN, STATE OR LOCAL TAX CONSEQUENCES OF
THE MERGER. ACCORDINGLY, YOU ARE STRONGLY URGED TO CONSULT WITH YOUR TAX ADVISOR
TO DETERMINE THE PARTICULAR UNITED STATES FEDERAL, STATE, LOCAL OR FOREIGN
INCOME OR OTHER TAX CONSEQUENCES TO YOU OF THE MERGER.

ACCOUNTING TREATMENT OF THE MERGER

     Broadbase intends to account for the merger as a purchase for financial
reporting and accounting purposes, under generally accepted accounting
principles. After the merger, Broadbase will include the results of operations
of Servicesoft in its consolidated financial statements. The purchase price from
the merger, estimated at $652.9 as of October 16, 2000, will be allocated based
on the fair values of the assets acquired and the liabilities assumed. Any
excess of cost over fair value of the net tangible assets of Servicesoft
acquired will be recorded as goodwill and other intangible assets and will be
amortized by charges to operations over their useful lives under generally
accepted accounting principles. These allocations will be made based upon
valuations and other studies that have not yet been finalized.

REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE MERGER

     The merger is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act, which prevents certain transactions from being
completed until required information and materials are furnished to the
Antitrust Division of the Department of Justice and the Federal Trade Commission
and the appropriate waiting periods end or expire. Broadbase, Servicesoft and
Sigma Partners IV, L.P., a Servicesoft stockholder which will, as a result of
the merger, make a reportable acquisition of Broadbase stock, have filed the
required information and materials with the Department of Justice and the
Federal Trade Commission. The requirements of Hart-Scott-Rodino will be
satisfied if the merger is completed within one year from the termination of the
waiting period.

     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the merger on antitrust grounds either before or after
expiration of the waiting period. Accordingly, at any time before or after the
completion of the merger, either the Antitrust Division of the Department of
Justice or the Federal Trade Commission could take action under the antitrust
laws. Certain other persons could take action under the antitrust laws,
including seeking to enjoin the merger. Additionally, at any time before or
after the completion of the merger, notwithstanding that the applicable waiting
period expired or ended, any state could take action under the antitrust laws. A
challenge to the merger could be made, and if a challenge is made, we may not
prevail.

     Neither of us is aware of any other material governmental or regulatory
approval required for completion of the merger, other than the effectiveness of
the registration statement of which this document is a part, and compliance with
applicable corporate law of Delaware.

RESTRICTIONS ON SALES OF SHARES BY AFFILIATES OF SERVICESOFT AND BROADBASE

     The shares of Broadbase common stock to be issued in the merger in exchange
for outstanding shares of Servicesoft stock will be registered under the
Securities Act. These shares will be freely transferable under the Securities
Act, except for shares of Broadbase common stock issued to any person who is an
affiliate of either of us. Persons who may be deemed to be affiliates include
individuals or entities that control, are controlled by, or are under common
control of either of us and may include some of our officers and directors, as
well as our principal stockholders. Affiliates of Servicesoft and Broadbase may
not sell shares of Broadbase common stock that they acquire in the merger except
pursuant to:

     - an effective registration statement under the Securities Act covering the
       resale of those shares;

     - an exemption under paragraph (d) of Rule 145 under the Securities Act; or

     - another applicable exemption under the Securities Act.

In addition, Servicesoft affiliates will be required, in conjunction with the
exchange of Servicesoft stock certificates for Broadbase stock certificates, to
agree not to sell any shares they receive in the merger until 90 days after the
merger is completed.

LISTING ON THE NASDAQ NATIONAL MARKET OF BROADBASE COMMON STOCK TO BE ISSUED IN
THE MERGER

     Broadbase will seek approval, subject to its filing an official notice of
issuance, for the listing on the Nasdaq National Market of the shares of its
common stock to be issued in the merger.

OPERATIONS OF THE COMBINED COMPANY AFTER THE MERGER

     After completion of the merger, Servicesoft will continue its operations as
a wholly-owned subsidiary of Broadbase. The stockholders of Servicesoft will
become stockholders of Broadbase, and their rights as stockholders will be
governed by Broadbase's certificate of incorporation and bylaws and by the laws
of Delaware. For additional information, please see the section entitled
"Comparison of Rights of Broadbase Stockholders and Servicesoft Stockholders"
beginning on page 104.

                              THE MERGER AGREEMENT

     This section describes the merger agreement. While we believe that the
description covers the material terms of the merger agreement, this summary may
not contain all of the information that is important to you. The merger
agreement is attached to this document as Annex A, and we urge you to read it in
its entirety.

REPRESENTATIONS AND WARRANTIES

     We each made representations and warranties in the merger agreement
regarding aspects of our respective businesses, financial conditions, ownership
structure and other facts pertinent to the merger. A summary of the
representations and warranties made by each company is provided below.

  Servicesoft's representations and warranties.

     Generally, Servicesoft's representations and warranties include
representations as to:

     - its and its subsidiaries' corporate organization, good standing and
       qualification to do business, and their certificates of incorporation and
       bylaws or other similar charter documents;

     - its subsidiaries, ownership interests in other entities and obligations
       to make future investments in entities;

OTHER AGREEMENTS

  Public announcements

     We each agreed that we will consult with the other before issuing any press
release or making any public announcement with respect to the merger. In
addition, Servicesoft agreed to take all reasonable precautions to prevent
trading in Broadbase's securities by officers, directors, employees and agents
of Servicesoft who have any material non-public information about Broadbase
until the information has been publicly disclosed.

  Fees and expenses

     Generally, each party agreed to pay the expenses and fees of its own
accountants, attorneys, investment bankers and other professionals incurred with
respect to the merger. However, Servicesoft's stockholders will be required to
indemnify the surviving corporation for fees and expenses in excess of $500,000
incurred by Servicesoft with respect to the merger, other than the fees and
expenses of investment bankers. Any such fees and expenses will be paid from the
escrow account. The parties will share equally in the fees and expenses, other
than attorneys' and accountants fees and expenses, incurred with respect to the
preparation of this document.

  Resale restrictions for Servicesoft affiliates

     The merger agreement specifies that, from the date of the merger agreement
until the date that is 90 days after the closing of the merger, no executive
officer, director or other affiliate of Servicesoft may transfer or otherwise
reduce its risk of ownership or investment in any shares of capital stock of
Broadbase. This restriction terminates if Broadbase enters into an agreement to
be acquired.

CONDUCT OF EACH COMPANY'S BUSINESS BEFORE THE CLOSING OF THE MERGER

     Servicesoft and Broadbase have each agreed that until the closing of the
merger, or unless the other consents in writing, each of them and its

its commercially reasonable efforts consistent with past practices and policies
to:

     - keep its present business intact;

     - keep available the services of its present officers;

     - preserve its relationships with customers, suppliers and others with
       which it has business dealings.

       course of business;

       outstanding options, plus additional options to purchase up to 200,000
       shares of Servicesoft common stock to be granted during the pre-closing

take any of the following actions without the prior written consent of
Servicesoft:

     - acquire or agree to acquire other entities, other than the acquisitions

       of more than 4,789,769 shares of Broadbase common stock;

     - issue any securities other than issuances of shares upon exercise of
       outstanding options and warrants, plus additional options to purchase up
       to 800,000 shares of Broadbase common stock under its employee benefit

       connection with permitted acquisitions, and certain option grants in

       stock, or redeem any of its capital stock;

     - change accounting practices or revalue its assets;

     - agree to or complete the sale of Broadbase to an acquirer; and

     - take any action that it knows will cause the merger to fail to qualify as
       a tax-free reorganization.

     The agreements related to the conduct of the companies' business in the
merger agreement are complicated and not easily summarized. We urge you to read
carefully the "Conduct of Business" sections of the merger agreement under the
articles of the merger agreement entitled "Servicesoft Pre-Closing Covenants"
and "Broadbase Pre-Closing Covenants."

NO OTHER NEGOTIATIONS

     Until the merger is completed or the merger agreement is terminated,
Servicesoft has agreed not to solicit or initiate certain kinds of corporate
transactions. The following terms will be used throughout this section and the
section entitled "Termination fee" beginning on page 83:

     - An Acquisition means any transaction or series of related transactions
       that results in the holders of record of an entity's capital stock
       immediately prior to that transaction or those transactions holding less
       than 50% of the voting power in that entity immediately after the
       transaction, or that results in a sale of all or substantially all of the
       assets of an entity.

     - An Acquisition Proposal means any offer or proposal relating to an
       Acquisition Transaction of Servicesoft, other than those contemplated by
       the merger agreement.

     - An Acquisition Transaction with respect to any entity means any
       transaction or series of related transactions, other than those
       contemplated by the merger agreement, involving:

        -- an acquisition or purchase from that entity of more than a 15%
           interest in the total outstanding voting securities of the entity or
           any of its subsidiaries;

        -- a tender offer or exchange offer that if consummated would result in
           any person or group holding 15% or more of the total outstanding
           voting securities of the entity or any of its subsidiaries; or

        -- any sale, exchange, transfer, acquisition or disposition, or any
           lease or license outside the ordinary course of business, of more
           than 10% of the assets of the entity, or any liquidation or
           dissolution of the entity.

     - A Superior Offer means an unsolicited, bona fide offer made by a third
       party to consummate either of the following transactions, and where
       Servicesoft's board of directors determines, in its reasonable judgment,
       based on the written advice of a financial advisor of national standing,
       to be more favorable to Servicesoft's stockholders than the terms of the
       merger with Broadbase:

        -- a merger or consolidation involving Servicesoft pursuant to which the
           stockholders of Servicesoft immediately preceding that transaction
           hold less than 50% of the equity interest in the surviving entity of
           that transaction; or

        -- an acquisition by any person or group, directly or indirectly, of
           ownership of 100% of the outstanding shares of capital stock of
           Servicesoft.

        An offer will not be a Superior Offer if any financing required to
        complete the transaction is not committed and is not likely in the
        reasonable judgment of Servicesoft's board of directors, based on the
        advice of its financial advisor, to be obtained on a timely basis.

                                       78
<PAGE>   86

  Servicesoft

     Until the merger is completed or the merger agreement is terminated,
Servicesoft has agreed not to, directly or indirectly:

     - solicit or initiate the making, submission or announcement of any
       Acquisition Proposal;

     - furnish to any person any non-public information with respect to any
       Acquisition Proposal;

     - take any other action to facilitate any inquiries regarding any
       Acquisition Proposal;

     - participate or engage in any discussions or negotiations with any person
       with respect to any Acquisition Proposal, except that Servicesoft may
       inform third parties, in response to unsolicited inquiries, of the
       provisions relating to non-solicitation in the merger agreement;

     - approve, endorse or recommend any Acquisition Proposal; and

     - enter into any letter of intent or similar document or any agreement
       contemplating or otherwise relating to any Acquisition Proposal.

     However, if Servicesoft receives a Superior Offer, then Servicesoft may
furnish non-public information regarding itself and its subsidiaries and may
enter discussions or negotiations with the party that has made the Superior
Offer, if:

     - neither Servicesoft nor any of its or its subsidiaries' representatives
       has violated any of the restrictions regarding non-solicitation;

     - Servicesoft's board of directors concludes, in good faith, after
       consultation with its outside legal counsel, that this action is required
       in order for the board of directors to comply with its fiduciary duties
       to Servicesoft's stockholders under applicable law;

     - prior to furnishing any non-public information to or entering into any
       discussions with the party making the offer, Servicesoft provides
       Broadbase with written notice of the identity of that party and the
       material terms and conditions of the offer;

     - the party making the offer signs a confidentiality agreement;

     - Servicesoft gives Broadbase at least two business days advance written
       notice of its intent to furnish non-public information to or enter into
       any discussions with the offeror; and

     - Servicesoft provides any non-public information to Broadbase at the same
       time that it provides the information to the party making the offer.

     If one of Servicesoft's advisors violates these requirements, the violation
will not be a breach of the merger agreement by Servicesoft if the violation was
not authorized by Servicesoft and Servicesoft terminates its relationship with
the advisor. Furthermore, Servicesoft agreed that it would immediately cease any
discussions with third parties with respect to any Acquisition Proposal.
Servicesoft has also agreed to inform Broadbase promptly as to any request for
non-public information or any other inquiry that Servicesoft believes is likely
to lead to an Acquisition Proposal, and of any actual Acquisition Proposal,
together with the identity of the person or group making any such request,
inquiry or Acquisition Proposal and any modifications to any such request,
inquiry or Acquisition Proposal.

  Broadbase

     Until the merger is completed or the merger agreement is terminated,
Broadbase has agreed not to directly or indirectly solicit or initiate the
making, submission or announcement of any Acquisition with respect to Broadbase.
If one of Broadbase's advisors violates this requirement, the violation will not
be a breach of the merger agreement by Broadbase if the violation was not
authorized by Broadbase and Broadbase terminates its relationship with the
advisor.

<PAGE>   87

STOCKHOLDER APPROVALS

     Each of Broadbase and Servicesoft has agreed to hold a special
stockholders' meeting as promptly as practicable after the SEC declared the
registration statement relating to this document effective and, in any event, no
more than 40 days after the effective date of the registration statement. Each
party has also agreed to solicit proxies from its stockholders in favor of the
approval of the merger-related proposals, and, subject to its directors'
fiduciary obligations, to use all reasonable efforts to take all other action
necessary or advisable to secure the required votes or consents approving the
merger-related proposals.

     Recommendation of Servicesoft's board of directors

     Servicesoft's board of directors unanimously recommends to Servicesoft's
stockholders that they approve the merger agreement and the merger.
Servicesoft's board can, without breaching the merger agreement, withhold,
withdraw or modify its recommendation in favor of the merger if:

     - a Superior Offer is made to Servicesoft and not withdrawn;

     - Servicesoft provides Broadbase with written notice of the Superior Offer,
       including the terms of the offer and the identity of the offeror;

     - Broadbase, within three business days after receiving notice of the
       Superior Offer, has not made another offer that Servicesoft's board of
       directors determines in good faith to be at least as favorable to
       Servicesoft's stockholders;

     - Servicesoft's board of directors concludes, in good faith, after
       consultation with its outside counsel, that, in light of the Superior
       Offer, withholding, withdrawing or modifying its recommendation is
       required in order for Servicesoft's board of directors to comply with its
       fiduciary obligations to Servicesoft's stockholders under applicable
       laws; and

     - Servicesoft has not violated any restrictions in the stockholder approval
       provisions and the non-solicitation provisions of the merger agreement.

     Servicesoft agreed further that it would provide Broadbase with at least
two business days prior notice, or the same notice as is given to Servicesoft's
board of directors, but not less than 24 hours prior notice, of any meeting of
Servicesoft's board of directors where the board is reasonably expected to
consider whether an Acquisition Proposal is a Superior Offer.

     Even if Servicesoft's board of directors changes its recommendation,
stockholders of Servicesoft that hold enough shares of Servicesoft stock to
approve the merger have already entered into voting agreements and agreed to
vote in favor of the merger.

     Recommendation by Broadbase's board of directors

     Broadbase agreed that its board of directors would unanimously recommend to
Broadbase's stockholders that they approve the issuance of shares of Broadbase
common stock in the merger. Broadbase's board of directors can, without
breaching the merger agreement, withhold, withdraw or modify its recommendation
in favor of the merger if:

     - Broadbase receives an unsolicited bona fide offer by a third party to
       consummate an Acquisition of Broadbase, where the third party requires as
       a condition to closing the proposed Acquisition that the merger agreement
       between Broadbase and Servicesoft be terminated and the combination of
       Broadbase and Servicesoft be abandoned;

     - Broadbase provides Servicesoft with written notice of the Acquisition
       offer described above, including the terms of the offer and the identity
       of the offeror; and

     - Broadbase's board of directors concludes, in good faith, after
       consultation with its outside legal counsel and a financial advisor of
       national standing, that, in light of this Acquisition offer, withholding,
       withdrawing or modifying such recommendation is required in order for
       Broadbase's

                                       80
<PAGE>   88

       board of directors to comply with its fiduciary obligations to
       Broadbase's stockholders under applicable laws.

LOANS

     Broadbase agreed to loan up to $15 million to Servicesoft, as needed by
Servicesoft for financing operating expenses until the merger is completed. For
a description of the terms of the loan, see the section of this document
entitled "Related Agreements--Convertible promissory note" on page 89.

EMPLOYEE BENEFITS PLANS

     Broadbase and Servicesoft will work together to agree on mutually
acceptable employee benefit and compensation arrangements. Servicesoft will
terminate its employee benefit plans as requested by Broadbase before the
closing of the merger, provided that employees of Servicesoft and its
subsidiaries, who are eligible to participate in each such Servicesoft employee
benefit plan will be given the opportunity to participate in a substantially
comparable employee benefit plan maintained by Broadbase. To the extent
permissible under Broadbase's employee benefit plans, Broadbase has agreed to
give full credit for all service provided to Servicesoft by its employees for
purposes of eligibility, vesting and benefits accrued. Servicesoft agreed to
terminate its severance, separation, retention and salary continuation plans,
programs or arrangements before the closing of the merger, other than the
employment agreements contemplated by merger agreement.

       Section 280G of the Internal Revenue Code, must have agreed to forfeit
       any payments that would otherwise be non-deductible if the requisite
       stockholder approval is not obtained.

     - Broadbase must have received signed copies of all material third-party
       consents, approvals, assignments, waivers, authorizations or other
       certificates required by the merger agreement and any other written

DEFINITION OF MATERIAL ADVERSE EFFECT

     The term material adverse effect, as used in the merger agreement means any
change, event, circumstance or effect that is materially adverse to the
business, employees, assets (including intangible assets), capitalization,
financial condition, operations or results of operations of such entity taken as
a whole with its subsidiaries, unless the entity can sustain the burden of
proving that any such change, event, circumstance or effect results from

     - changes in general economic conditions, or

     - changes affecting the industry generally in which the entity operates
       which do not affect such entity disproportionately.

TERMINATION OF THE MERGER AGREEMENT

     The merger agreement may be terminated and the merger abandoned at any time
before the closing of the merger, whether before or after approval by
Servicesoft's stockholders:

     - by the mutual written consent of Broadbase and Servicesoft;

     - by either Broadbase or Servicesoft if the party who seeks to terminate
       the merger agreement is not in material breach of any representation,
       warranty, covenant or agreement contained in the agreement, and the other
       party is in material breach of any representation, warranty, covenant or
       agreement contained in the merger agreement, or if any representation of
       the other party has become untrue, in either case to an extent that would
       cause the merger closing conditions not to be

                                       83
<PAGE>   91

       satisfied and the breaching party fails to cure the material breach
       within 15 days of receiving written notice of the breach from the
       non-breaching party;

     - by either Servicesoft or Broadbase if the merger is not completed by
       February 28, 2001 for any reason, except that this right to terminate the
       merger agreement will not be available to a party where that party's
       action or failure to act was a principal cause of or resulted in the
       failure of the merger to occur on or before such date and the action or
       failure to act constituted a breach of the merger agreement;

     - by either Servicesoft or Broadbase if there is a final nonappealable
       order of a federal or state court in effect preventing completion of the
       merger, or if any statute, rule, regulation or order becomes applicable
       to the merger that would make completion of the merger illegal; and

     - by either Servicesoft or Broadbase if the required approval of either
       company's stockholders contemplated by the merger agreement has not been
       obtained, except that this right to terminate the agreement will not be
       available to a party where the failure to obtain the approval of its own
       stockholders was caused by an action or failure to act by that party that
       constitutes a material breach of the merger agreement.

     If either of us wants to terminate the merger agreement, we must deliver to
the other party a written notice stating that we are terminating the agreement
and setting forth a brief description of the basis for the termination. The
termination of the merger agreement will be effective upon the delivery of such
notice.

TERMINATION FEES

     Payment by Servicesoft

     If either Broadbase or Servicesoft terminates the merger agreement because
of a failure to obtain the required consent of Servicesoft's stockholders,
Servicesoft must, within two days of the termination, pay $12.5 million to
Broadbase. If Broadbase terminates the merger agreement because of an uncured
material breach of the merger agreement by Servicesoft, and

     - prior to the termination of the merger agreement, a person has publicly
       announced an Acquisition Proposal with respect to Servicesoft and

     - within nine months after the termination of the merger agreement, either
       an Acquisition Transaction with respect to Servicesoft is completed, or
       Servicesoft enters into an agreement providing for an Acquisition
       Transaction,

then Servicesoft must pay $12.5 million to Broadbase within two days of the
completion of the Acquisition Transaction.

     Payment by Broadbase

     If either Broadbase or Servicesoft terminates the merger agreement because
of a failure to obtain the required consent of Broadbase's stockholders,
Broadbase must, within two days of the termination, pay $12.5 million to
Servicesoft. If Servicesoft terminates the merger agreement because of an
uncured material breach of the merger agreement by Broadbase, and

     - prior to the termination of the merger agreement, a person has publicly
       announced a proposal for the Acquisition of Broadbase and

     - within nine months after the termination of the merger agreement, either
       an Acquisition Transaction with respect to Broadbase is completed, or
       Broadbase enters into an agreement providing for an Acquisition
       Transaction,

then Broadbase must pay $12.5 million to Servicesoft within two days of the
completion of the Acquisition Transaction.

                                       84
<PAGE>   92

     If any principal or interest under any of the loans advanced by Broadbase
to Servicesoft under the merger agreement remain outstanding at the date of the
termination, then the fee payable by Broadbase pursuant to these provisions will
be reduced by the amount of the outstanding loans owed by Servicesoft.

     Special payment by Broadbase

     If the merger agreement is terminated by Broadbase or Servicesoft because
of a failure to obtain the required approval of Broadbase's stockholders, and
either

     - this document did not include a recommendation by Broadbase's board of
       directors that Broadbase's stockholders vote in favor of the merger, or

     - Broadbase's board of directors otherwise withdrew, amended or modified
       its recommendation that Broadbase's stockholders vote in favor of the
       merger,

then the outstanding principal and any accrued interest on the loans advanced by
Broadbase to Servicesoft will be immediately deemed to have been repaid in full,
and any remaining amount available under the loans will be paid to Servicesoft
in addition to the termination fee discussed above.

INDEMNIFICATION OBLIGATIONS OF SERVICESOFT'S STOCKHOLDERS

     Servicesoft's stockholders are required, as part of the merger, to
indemnify Broadbase and its representatives for claims arising under the merger
agreement. Ten percent of the shares of Broadbase common stock to be issued to
the Servicesoft stockholders in the merger will be withheld and transferred to
an escrow account as security for these indemnification obligations.

     Subject to the limitations described below, the stockholders of Servicesoft
will each indemnify Broadbase and its representatives from and against any and
all claims and liabilities, including reasonable legal fees and costs, directly
or indirectly arising or resulting under the merger agreement, including:

     - breaches of the representations and warranties in the merger agreement,

     - any expenses of Servicesoft for accountants, attorneys and other
       professionals, other than for the fees and expenses of investment
       bankers, incurred with respect to the merger agreement, to the extent
       these fees exceed $500,000; or

     - any failure of any Servicesoft stockholder to have proper title to the
       shares of Servicesoft's stock that they submit for exchange, except that,
       for this kind of indemnification claim, the indemnified parties can only
       recover damages from the particular stockholder who failed to have proper
       title.

  Limitations on indemnification obligations

     Except for indemnification with respect to fees and expenses of
professionals in excess of $500,000 and claims relating to ownership of the
Servicesoft stock exchanged in the merger, the indemnification provided for by
the merger agreement will not apply until the aggregate indemnification claims
exceed $1,000,000, at which point the indemnification obligations of the
stockholders will include the aggregate of all the indemnification claims.

     The indemnified parties cannot initiate any claim for damages under the
merger agreement after expiration of the escrow on the first anniversary of the
closing of the merger. Except with respect to claims involving intentional fraud
or relating to ownership of the shares of Servicesoft stock exchanged in the
merger, the shares of Broadbase stock held in escrow will be the exclusive
source of remedy of the indemnified parties against any Servicesoft stockholder
under any theory of liability. The maximum liability of a Servicesoft
stockholder for claims related to ownership of Servicesoft stock exchanged in
the merger or claims of intentional fraud by persons other than that stockholder
is limited to the shares of Broadbase stock received in the merger. There is no
limit to the liability of a stockholder for claims of intentional fraud by that
stockholder.

                                       85
<PAGE>   93

     For claims of intentional fraud, Broadbase has agreed to seek
indemnification first against the shares held in escrow pro rata and that it
will only be entitled to receive indemnification for those claims directly from
the Servicesoft stockholders if all of the shares withheld in escrow have
already been released to it in accordance with escrow agreement.

  Escrow

     Broadbase will deposit 10% of the shares to be issued in the merger in
exchange for Servicesoft stock into an escrow account as security for the
indemnification obligations of the Servicesoft stockholders. The shares will be
deducted, pro rata, from each Servicesoft stockholder's merger consideration and
deposited with State Street Bank and Trust Company of California, N.A., which
will serve as the escrow agent. In addition, any tax-free stock dividends with
respect to the shares withheld in escrow in order to effect a stock split of
Broadbase's common stock will also be held in the escrow account. Shares
remaining in the escrow account (and any other property held in escrow) at the
end of the escrow period will be released within five days of that date to the
Servicesoft stockholders in accordance with their relative interests in the
escrow shares. The escrow period will end at 12:01 a.m. on the first anniversary
of the date of the closing of the merger. For a description of the escrow
agreement governing the escrow account, see the section of this document
entitled "Related agreements -- Escrow agreement" on page 89.

  Related agreements of Servicesoft's stockholders

     Servicesoft's stockholders, by their approval of the merger and/or the
tender of their stock certificates in exchange for Broadbase stock certificates,
will be deemed to agree to:

     - the indemnification provisions of the merger agreement;

     - the terms of the escrow agreement;

     - the appointment of Mark S. Skapinker, the current Chairman of
       Servicesoft's board of directors, as their representative under the
       escrow agreement and as their attorney-in-fact and agent, as provided in
       the escrow agreement; and

     - the authorization of this representative to take any actions or make any
       decisions required or permitted under the escrow agreement.

  Liability of the representative

     In general, neither the representative nor any of his partners, members,
directors, officers, employees or agents will be liable to any of Servicesoft's
stockholders in connection with his services pursuant to the merger agreement,
unless the damages are caused by his own gross negligence or willful misconduct.

AMENDMENT, EXTENSION AND WAIVER OF THE MERGER AGREEMENT

     At any time prior to the closing of the merger, we may amend the merger
agreement if the party to be bound by the change signs the amendment. Either of
us can extend the other's time for the performance of any of the obligations or
other acts under the merger agreement, waive any inaccuracies in the other's
representations and warranties and waive compliance by the other with any of the
agreements or conditions contained in the merger agreement.

                               RELATED AGREEMENTS

     This section of the document describes the following agreements related to
the merger agreement: voting agreements, an escrow agreement, a form of
convertible promissory note and employment agreements. While we believe that
these descriptions cover the material terms of the agreements, they are
summaries and may not contain all the information that is important to you. The
voting agreements are attached to this document as Annexes C and D, and the
escrow agreement is attached as Annex E. We urge you to read each of these
documents carefully.

VOTING AGREEMENTS

     Each of the parties required a certain percentage of the other's
stockholders to enter into voting agreements before signing the merger
agreement.

  Servicesoft stockholders

     The voting agreement for Servicesoft's stockholders, between Broadbase and
each of the relevant Servicesoft stockholders, requires each signing stockholder
to vote its Servicesoft stock in favor of the merger agreement and the merger,
and against any proposals in opposition to or competition with the merger. As
part of the agreement, each such stockholder also granted Broadbase an
irrevocable proxy to vote the stockholder's shares of Servicesoft stock at the
Servicesoft special meeting.

     Stockholders holding the following percentages of Servicesoft's capital
stock, measured at the record date and organized by classes entitled to vote,
entered into the voting agreement prior to the signing of the merger agreement:

     -   % of the voting power of the Servicesoft common stock and preferred
       stock, voting together; and

     -   % of the voting power of the Servicesoft preferred stock.

     For purposes of the votes to be considered regarding the merger, the
holders of exchangeable common stock of Servicesoft Canada vote with the holders
of Servicesoft common stock, and the holders of exchangeable preferred stock of
Servicesoft Canada vote with the holders of Servicesoft Series H preferred
stock.

     The stockholders who signed the voting agreement also agreed not to sell or
transfer their Servicesoft stock, or to enter into any other voting agreements
with respect to their Servicesoft stock, until the termination of the voting
agreement. The voting agreement will terminate upon the earlier of the
termination of the merger agreement or the completion of the merger.

  Broadbase stockholders

     The voting agreement between Servicesoft and each of the relevant Broadbase
stockholders requires each signing stockholder to vote its Broadbase stock in
favor of the issuance of the shares in the merger, in favor of an amendment to
Broadbase's certificate of incorporation increasing the authorized number of
shares of Broadbase common stock to permit the issuance of the shares in the
merger and, to the extent required by applicable law, in favor of the merger
agreement and the merger and against any proposals in opposition to or
competition with the merger. As part of the agreement, each such stockholder
also granted Servicesoft an irrevocable proxy to vote the stockholder's shares
of Broadbase stock at the Broadbase special meeting. Stockholders representing
  % of the outstanding shares of Broadbase common stock as of the record date
for the stockholders' meeting entered into the voting agreement prior to the
signing of the merger agreement. The stockholders who signed the voting
agreement also agreed not to enter into any other voting agreements with respect
to their Broadbase stock until the termination of the voting agreement. The
voting agreement will terminate upon the earlier of the termination of the
merger agreement or the completion of the merger.

                                       87
<PAGE>   95

ESCROW AGREEMENT

     The parties have agreed on a form of escrow agreement to be executed by
Broadbase, Mark S. Skapinker, the current Chairman of Servicesoft's board of
directors, as the representative of the Servicesoft stockholders, and by State
Street Bank and Trust Company of California, the escrow agent, prior to the
closing of the merger. The escrow agreement contains provisions governing the
following:

     - the procedures for Broadbase and its agents to bring claims against the
       escrow account and for Mr. Skapinker to dispute these claims in his
       capacity as the stockholder representative;

     - the timing and manner of the release of the shares and other property (if
       any) withheld in escrow; and

     - the duties and limitations of liability for the escrow agent.

     While shares issued by Broadbase in the merger remain in escrow, the former
Servicesoft stockholders will be able to vote the shares, but may not sell,
assign, transfer, pledge or otherwise encumber them, except for transfers made
for estate planning purposes and transfers by operation of law or laws of
descent and distribution.

CONVERTIBLE PROMISSORY NOTE

     The parties also have agreed upon a form of promissory note that will be
issued by Servicesoft to Broadbase in exchange for each loan from Broadbase to
Servicesoft of up to a total of $15 million, as needed by Servicesoft, under the
merger agreement. Generally, payment of the notes is due December 31, 2002.
However, if the merger agreement is terminated before the closing of the merger,
the notes will become due and payable by Servicesoft one year after the date of
that termination. If Servicesoft raises funds by selling shares of its stock
before the due date, then Broadbase can require Servicesoft to apply up to 50%
of the funds received by Servicesoft in that financing toward repayment of the
loans, and Servicesoft must repay any remaining portion on the first anniversary
of the termination date. In addition, Broadbase can require full repayment of
the loans if Servicesoft is acquired during this period.

     The unpaid principal amounts under the promissory notes will accrue
interest at a rate of 8.5% per year. If Servicesoft fails to repay the notes
when due, Broadbase can elect to convert any outstanding principal and interest
under notes into Servicesoft common stock at $10.00 per share. In addition, if
the merger agreement is terminated and Servicesoft sells shares of its stock in
a fundraising transaction, Broadbase can elect to convert any outstanding
principal and interest into the type of Servicesoft stock sold in that
transaction at the price per share paid in that fundraising transaction. To
date, Servicesoft has issued convertible promissory notes representing
$          in aggregate principal amount to Broadbase.

     If Servicesoft defaults on any of the notes and does not cure the default
or pay off the note within 10 days of receiving notice of the default from
Broadbase, Broadbase can declare the debt represented by that note immediately
due and payable in full, and can elect to increase the applicable interest rate
by the lesser of four percent or the highest rate permitted under applicable
usury laws. The new interest rate would become effective on the date of the
election notice from Broadbase. Servicesoft will be deemed in default on the
note if:

     - it fails to pay when due any principal, interest or fees payable under
       the note;

     - any of its representations or warranties contained in the note proves to
       be materially incorrect;

     - it fails to comply with any covenant in the merger agreement and fails to
       cure it within ten days of its occurrence (provided the merger agreement
       is still in effect);

     - it becomes subject to various kinds of bankruptcy proceedings; or

     - it fails to perform or observe any agreements relating to its debt, where
       the debt represented by such agreements totals, in the aggregate, more
       than $1,000,000.

                                       88

EMPLOYMENT AGREEMENTS

     Prior to the execution of the merger agreement, Massood Zarrabian, Paul R.
Maguire, Alf Saggesse and Daniel J. Kossmann of Servicesoft entered into
employment agreements with Broadbase and will be employed by Broadbase after the
completion of the merger. Each employment agreement sets forth the employee's
position, duties, scope of employment and compensation with Broadbase. Under the
terms of these employment agreements, each of these employees will be "at will"
employees. In addition to salary and Broadbase's assumption of options and
restricted stock, Messrs. Zarrabian's and Kossmann's compensation packages will
include partial acceleration of the vesting of their Servicesoft options assumed
by Broadbase.

     Each of the agreements provides a severance package in case any of the
employees is terminated by Broadbase without cause or if Broadbase improperly
changes the employee's duties or fails to pay a material portion of the
employee's consideration, and the employee then leaves Broadbase. The severance
arrangement provides for a cash payment and for acceleration of vesting with
respect to restricted stock and options held by the employees.

     Under the agreements, each of these employees was required to sign
Broadbase's standard Proprietary Information and Inventions Agreement.
Furthermore, all of the employees except Mr. Kossmann entered into
non-competition agreements with Broadbase, prohibiting them from competing with
Broadbase for the longer of one year after the closing of the merger and one
year after termination of their employment. The prohibited activities include:

     - being connected to any other business engaged in developing and marketing
       software in the field of customer relationship management or any business
       engaged in developing any product or providing any services that is
       substantially the same as customer relationship management software;

     - recruiting away employees of Broadbase or Servicesoft; and

     - soliciting Broadbase or Servicesoft customers to sell them products that
       compete with those of Broadbase or Servicesoft.

     The trading price of Broadbase common stock may fluctuate. However, the
exchange ratio will not be adjusted to compensate Servicesoft stockholders for
decreases in the market price of Broadbase common stock which could occur before
the merger is completed. Accordingly, if the market price of Broadbase common
stock decreases before the merger is completed, the value of the Broadbase
common stock to be received in the merger in exchange for Servicesoft common
stock would correspondingly decrease. Servicesoft stockholders are urged to
obtain current market quotations for Broadbase common stock on the Nasdaq
National Market.

SERVICESOFT

     The common stock of Servicesoft is not presently traded on an established
public trading market.

DIVIDENDS

     Neither Broadbase nor Servicesoft has ever paid cash dividends on their
respective shares of capital stock. Pursuant to the merger agreement, each of
Broadbase and Servicesoft has agreed not to pay cash dividends before the
closing of the merger without the written consent of the other. If the merger is
not completed, Servicesoft presently intends that, if the merger is not
completed, it would retain future earnings, if any, for use in its business and
would not pay any cash dividends in the foreseeable future.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

     The following unaudited pro forma combined condensed financial statements
give effect to Broadbase's acquisitions of Rubric, Inc. in February 2000 and
Panopticon, Inc. in September 2000, and Broadbase's proposed acquisition of
Servicesoft. The acquisitions of both Rubric and Panopticon were recorded using
the purchase method of accounting for business combinations; when completed, the
acquisition of Servicesoft will also be recorded using the purchase method of
accounting. The following pro forma statements reflect these acquisitions using
the purchase method of accounting for business combinations and include the pro
forma adjustments described in the accompanying notes.

     The pro forma combined condensed balance sheet as of June 30, 2000 combines
Broadbase's, Panopticon's and Servicesoft's consolidated balance sheets as of
June 30, 2000 as if the acquisitions had been consummated on that date. Because
Broadbase's acquisition of Rubric was completed on February 1, 2000, the effect
of this transaction is already reflected in Broadbase's consolidated balance
sheet at June 30, 2000.

     The pro forma combined condensed statement of operations of Broadbase for
the year ended December 31, 1999 and the six months ended June 30, 2000 assume
that the acquisitions of Rubric, Panopticon and Servicesoft took place on
January 1, 1999.

     Broadbase's, Rubric's and Panopticon's results, included in the pro forma
combined condensed statements of operations for the year ended December 31, 1999
is derived from their respective December 31, 1999 audited financial statements.
Broadbase's and Panopticon's results included in the pro forma combined
condensed balance sheet as of June 30, 2000 and pro forma combined condensed
statements of operations for the six months ended June 30, 2000 are derived from
their respective June 30, 2000 unaudited consolidated financial statements. All
of these financial statements are or will be incorporated by reference into this
document.

     The Servicesoft's results included in the pro forma combined condensed
statement of operations for the year ended December 31, 1999 are derived from
Servicesoft's unaudited pro forma combined financial statements included
elsewhere in this document. These unaudited pro forma combined financial
statements give effect to Servicesoft's acquisitions of Balisoft Technologies,
Inc. and Internet Business Advantages, Inc. as if they had been completed on
January 1, 1999. These acquisitions by Servicesoft were recorded using the
purchase method of accounting. Servicesoft's condensed financial information as
of and for the six months ended June 30, 2000 included in the pro forma
financial statements is derived from Servicesoft's June 30, 2000 unaudited
consolidated financial statements, which are included elsewhere in this proxy
statement/prospectus.

     The unaudited condensed consolidated financial information of Broadbase,
Rubric, Panopticon and Servicesoft has been prepared in accordance with
generally accepted accounting principles applicable to interim financial
information and, in the opinion of management, includes all adjustments
necessary for a fair presentation of the financial information for such interim
periods.

     The unaudited pro forma combined condensed information is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have actually occurred if the
acquisitions had been consummated as of the date indicated, nor is it
necessarily indicative of future operating results or financial position. The
pro forma adjustments are based on the information available at the date of this
document and are subject to change based upon completion of the transactions and
final purchase price allocations, including completion of third party
appraisals.

     Broadbase issued 5,984,192 shares of its common stock, valued at $50.42 per
share, the average market price per share of Broadbase common stock in a range
of seven trading days before and after December 9, 1999, the announcement date
of the acquisition. In addition, Broadbase issued 1,216,000 options and warrants
to purchase shares of its common stock in exchange for all options and warrants
to purchase shares of Rubric common stock. The value of the options and warrants
to be issued by Broadbase was determined by estimating their fair value as of
December 9, 1999 using the Black-Scholes option pricing model with the following
weighted average assumptions:

     - risk free interest rate of 5.0%;

     - dividend yield of 0.0%;

     - expected life of 0.5 years for vested options and warrants;

     - expected life of 3.4 years for unvested options and warrants; and

     - volatility factor for the expected market price of Broadbase common stock
       of 0.60.

     Tangible assets of Rubric acquired principally included cash and cash
equivalents, accounts receivable, fixed assets, and other assets. Liabilities of
Rubric assumed principally included accounts payable, accrued liabilities,
capital lease obligations, and long-term debt.

     To determine the value of the developed technology, the expected future
cash flows attributable to all existing technology was discounted, taking into
account risks related to the characteristics and applications of the developed
technology, existing and future markets, and assessments of the stage of the
technology's life cycle. The analysis resulted in a valuation for developed
technology that had reached technological

                                       95
<PAGE>   103

feasibility and therefore was capitalizable. The developed technology is being
amortized on a straight-line basis over one year.

     The value allocated to projects identified as in-process research and
development of the Rubric eMA product release version 3.0 and 4.0 was charged to
expense in February 2000 immediately following the completion of the Rubric
acquisition. This write-off was necessary because the acquired in-process
research and development had not yet reached technological feasibility and had
no future alternative uses, and the related products under development may not
have achieved commercial viability. The nature of the efforts required to
develop the purchased in-process research and development into commercially
viable products principally relate to the completion of all planning, designing,
prototyping, verification and testing activities that are necessary to establish
that the product can be produced to meet its design specifications, including
functions, features and technical performance requirements.

     The value of the purchased in-process research and development was
determined by estimating the projected net cash flows related to the products,
including costs to complete the development of the technology and the future
revenues to be earned upon commercialization of the products. These cash flows
were then discounted back to their net present value. The projected net cash
flows from the project were based on management's estimates of revenues and
operating profits related to the projects.

     To determine the revenue attributable to the in-process technology,
consideration was also given to the contribution of the existing technology
which will be utilized in the development of the in-process technology, referred
to as "core technology." The value allocated to the core technology was
determined by assigning a "leverage factor" of 25% to the estimated projected
net cash flows related to the products under development after analysis of both
the effort and work completed as well as the expected value of the in-process
technology. The projected net cash flows attributable to core technology using
the leverage factor were then discounted back to their net present value. The
core technology is being amortized over its estimated useful life of five years.

     The value allocated to the assembled workforce is attributable to the
Rubric workforce in place after the acquisition, which eliminated the need to
hire new replacement employees. The value was determined by estimating the cost
involved in assembling a new workforce, including costs of salaries, benefits,
training and recruiting. The value of the assembled workforce is being amortized
on a straight-line basis over three years.

     The value of the Rubric tradename was determined by considering, among
other factors, the assumption that in lieu of ownership of the tradename, a
third party would be willing to pay a royalty in order to exploit the related
benefits of such tradename. Estimated royalties to be received over the next
four years were then discounted to their present value using an appropriate rate
of return. The value of tradename is being amortized on a straight-line basis
over five years.

     The value of the OEM distribution contract was determined by computing the
present value of the estimated net cash flows to be generated over three years,
the remaining life of the agreement at the time the Rubric acquisition closed.
This asset is being amortized on a straight-line basis over three years.

     Goodwill was determined based on the residual difference between the amount
of consideration paid and the values assigned to identifiable tangible and
intangible assets. The goodwill is being amortized on a straight-line basis over
five years.

     A charge for in-process research and development of $10.1 million
attributable to the completed purchase of Rubric on February 1, 2000, has been
excluded from the pro forma combined condensed statement of operations for the
year ended December 31, 1999 because it is non-recurring, but has been included
in the pro forma combined condensed balance sheet at June 30, 2000 and the pro
forma combined condensed statement of operations for the six months ended June
30, 2000 because Broadbase recorded this amount in its historical financial
statements upon close of the transaction.

     Costs of integrating the operations of Broadbase and Rubric and other
merger-related costs of $10.2 million are included in the pro forma combined
condensed statement of operations for the six

                                       96
<PAGE>   104

months ended June 30, 2000 because these costs were incurred and recorded by
Broadbase during the period. However, these charges have not been included in
the pro forma combined condensed statement of operations for the year ended
December 31, 1999 because at the time of the merger they represented costs which
would affect future operations and did not qualify as liabilities in connection
with a purchase business combination under EITF 95-3, "Recognition of
Liabilities in Connection with a Purchase Business Combination."

     Broadbase issued 2,659,808 shares of its common stock, valued at $32.09 per
share, the average market price per share of Broadbase common stock in a range
of seven trading days before and after the announcement date (July 7, 2000) of
the acquisition. In addition, Broadbase issued 534,824 options and warrants to
purchase shares of its common stock in exchange for all options and warrants to
purchase shares of Panopticon common stock. The value of the options and
warrants to be issued by Broadbase was determined by estimating their fair value
as of July 7, 2000 using the Black-Scholes option pricing model with the
following weighted average assumptions:

     - risk free interest rate of 5.90% to 5.97%

     - dividend yield of 0.0%

     - expected life of 0.5 years for vested options.

     - expected life of 2.9 to 3.5 years for unvested options and warrants.

     - volatility factor for the expected market price of Broadbase common stock
       of 0.60.

     Tangible assets of Panopticon acquired principally included cash and cash
equivalents and other assets. Liabilities of Panopticon assumed principally
included accrued liabilities and short-term debt.

upon the close of the merger. This write-off was necessary because the acquired
in-process research and development had not yet reached technological
feasibility and had no future alternative uses, and the related products under
development may not have achieved commercial viability. The nature of the
efforts required to develop the purchased in-process research and development
into commercially viable products principally relate to the completion of all
planning, designing, prototyping, verification and testing activities that are
necessary to establish that the products could be produced to meet their design
specifications, including functions, features and technical performance

including costs to complete the development of the technology and the future
revenues to be earned upon commercialization of the products. These cash flows
were then discounted back to their net present value. The projected net cash
flows from the project were based on management's estimates of revenues and
operating profits related to the projects.

     To determine the revenue attributable to the in-process technology,
consideration was also given to the contribution of the existing technology
which will be utilized in the development of the in-process technology, referred
to as "core technology." The value allocated to the core technology was
determined by assigning a "leverage factor" of 15% to the estimated projected
net cash flows related to the products under development after analysis of both
the effort and work completed as well as the expected value of the in-process
technology. The projected net cash flows attributable to core technology using
the leverage factor were then discounted back to their net present value. The
core technology is being amortized over its estimated useful life of five years.

     The value allocated to the assembled workforce is attributable to the
Panopticon workforce in place after the acquisition, which eliminated the need
to hire new replacement employees. The value was determined by estimating the
cost involved in assembling a new workforce including costs of salaries,
benefits, training and recruiting. The value of the assembled workforce is being
amortized on a straight-line basis over three years.

     The value allocated to the patent application was determined by
considering, among other factors, the assumption that in lieu of ownership of
the patent applications, a third party would be willing to pay a royalty in
order to exploit the related benefits of such patent applications. Estimated
royalties to be received over the next four years were then discounted to their
present value using an appropriate rate of return. This asset is being amortized
on a straight-line basis over three years.

     Deferred compensation represents a portion of the estimated intrinsic value
of unvested Panopticon stock options assumed by Broadbase in the merger
agreement to the extent that employee service is required after the closing date
of the acquisition in order to vest. In March 2000, the Financial Accounting
Standards Board issued FASB Interpretation No. 44, Accounting for Certain
Transactions Involving Stock Compensation, an Interpretation of APB No. 25. The
interpretation, which is effective as of July 1, 2000, requires that the
intrinsic value of assumed unvested options be recorded as compensation expense
subsequent to the merger over the remaining term of the option's vesting period,
whereas options assumed from mergers and acquisitions prior to July 2000
resulted in no compensation charges but were included in Broadbase's allocation
of purchase price consideration as a component of goodwill. Broadbase is
amortizing the value assigned to deferred compensation on a graded vesting
method over the remaining vesting period of each option of up to three and
one-half years.

     Goodwill was determined based on the residual difference between the amount
of consideration to be paid and the values assigned to identifiable tangible and
intangible assets. The goodwill is being amortized on a straight-line basis over
five years.

     A charge for in-process research and development attributable to the
purchase of Panopticon of $2.8 million has been included in accumulated deficit
in the pro forma combined condensed balance sheet, but has been excluded from
the pro forma combined condensed statements of operations because the charge is
non-recurring.

     Broadbase anticipates issuing approximately 28,962,828 shares of its common
stock, valued at $18.75 per share, the average market price per share of
Broadbase common stock in a range of seven trading days before and after

Broadbase anticipates issuing approximately 6,097,617 options and warrants to
purchase shares of its common stock in exchange for all options and warrants to

warrants to be issued by Broadbase was determined by estimating their fair value
as of September 18, 2000 using the Black-Scholes option pricing model with the
following weighted average assumptions:

     - risk free interest rate of 6.02% to 6.17%;

     - dividend yield of 0.0%;

     - expected life of 0.5 years for vested options;

     - expected life of 3 to 4 years for unvested options and warrants; and

     - volatility factor for the expected market price of Broadbase common stock
       of 0.60.

     Tangible assets of Servicesoft principally include cash and cash
equivalents, accounts receivable, fixed assets and other assets. Liabilities of
Servicesoft that would be assumed by Broadbase principally include accounts
payable, accrued liabilities and capital lease obligations.

     To determine the value of the developed technology, the expected future
cash flows attributable to all existing technology was discounted, taking into
account risks related to the characteristics and applications of the developed

feasibility and therefore was capitalizable. The developed technology will be
amortized on a straight-line basis over one year.

     The value allocated to projects identified as in-process research and
development of the next generation of Servicesoft's product suite will be
charged to expense by Broadbase immediately following the completion of the
Servicesoft acquisition, but has not been reflected in the Broadbase proforma
combined condensed statements of operations as it is non-recurring in nature.
This write-off will be necessary because the acquired in-process research and
development has not yet reached technological feasibility and has no future
alternative uses, and the related products under development may not achieve
commercial viability. The nature of the efforts required to develop the
purchased in-process research and development into commercially viable products
principally relate to the completion of all planning, designing, prototyping,

of such tradename. Estimated royalties to be received over the next four years
were then discounted to their present value using an appropriate rate of return.
The value assigned to the tradename will be amortized on a straight-line basis
over five years.

     The value of Servicesoft's customer base was determined by computing the
present value of the estimated net cash flows to be generated from payment of
maintenance fees and service contracts from Servicesoft's existing customer
base. The value of this customer basis will be amortized on a straight-line
basis over two years.

     Deferred compensation represents a portion of the estimated intrinsic value
of unvested Servicesoft stock options assumed by Broadbase in the merger
agreement to the extent that employee service is required after the closing date
of the merger in order for the options to vest. In March 2000, the Financial
Accounting Standards Board issued FASB Interpretation No. 44, Accounting for

25. The interpretation, which became effective as of July 1, 2000, requires that
the intrinsic value of assumed unvested stock options be recorded as
compensation expense subsequent to the merger over the remaining term of the

prior to July 2000 resulted in no compensation charges but were included in
Broadbase's allocation of purchase price consideration as a component of

                                       100
<PAGE>   108

goodwill. Broadbase will amortize the value assigned to deferred compensation on
a graded vesting method over the remaining vesting period of each option of up
to four years.

     Goodwill is determined based on the residual difference between the amount
of consideration to be paid and the values assigned to identifiable tangible and
intangible assets. The goodwill will be amortized on a straight-line basis over
five years.

     A charge for in-process research and development attributable to the
purchase of Servicesoft of $13.0 million has been included in accumulated
deficit in the pro forma combined condensed balance sheet, but has been excluded
from the pro forma combined condensed statements of operations because the
charge is non-recurring.

PRO FORMA NET LOSS PER SHARE

     Pro forma basic and diluted net loss per share are based on the weighted
average number of shares of Broadbase common stock outstanding during the period
and the number of shares of Broadbase common stock issued or to be issued in

                            COMPARISON OF RIGHTS OF
                           BROADBASE STOCKHOLDERS AND
                            SERVICESOFT STOCKHOLDERS

     This section of the document summarizes the differences between Broadbase
stock and Servicesoft stock. While we believe that the description covers the
material differences between the two, this summary may not contain all of the
information that is important to you. You should read this entire document and
the other documents we refer to carefully for a more complete understanding of
the differences between Broadbase stock and Servicesoft stock.

     After the merger, the holders of Servicesoft stock will become stockholders
of Broadbase. Because Broadbase and Servicesoft are both Delaware corporations,
the Delaware General Corporation Law, or the DGCL, will continue to govern the
rights of these stockholders. The Servicesoft certificate of incorporation and
bylaws currently govern the rights of the Servicesoft stockholders. After the
merger, the Broadbase certificate of incorporation and bylaws will instead
govern their rights.

     This summary reflects the changes to Broadbase's certificate of
incorporation that Broadbase's board of directors approved on                ,
2000, and that Broadbase stockholders are being asked to approve at the
Broadbase stockholders' meeting.

VOTES PER SHARE

     Broadbase.  Broadbase's bylaws provide that each Broadbase stockholder has
the right to one vote for each share of stock held by such stockholder.

     Servicesoft.  Servicesoft's certificate of incorporation and bylaws provide
that, except as otherwise provided by law, the holders of shares of common stock
shall be entitled to one vote for each share so held with respect to all matters
voted on by the stockholders of the corporation. Servicesoft's certificate of
incorporation provides that each share of convertible preferred stock entitles
the holder to the number of votes per share on each such action equal to the
number of shares of common stock, including fractions of a share rounded up to
the nearest whole number, into which each such share of convertible preferred
stock is then convertible.

     Servicesoft also has outstanding one share each of Series X preferred stock
and Series Y preferred stock. These shares are held by a trustee for the holders
of exchangeable preferred stock and exchangeable common stock of Servicesoft
Canada under a Voting and Exchange Trust Agreement. Under this Agreement, the
holders of exchangeable common stock are entitled to exercise voting rights
equivalent to voting rights attaching to the same number of shares of
Servicesoft common stock through the trustee of the share of Series X preferred
stock. Also under this agreement, the holders of exchangeable preferred stock
are entitled to exercise voting rights equivalent to voting rights attaching to
the same number of shares of Servicesoft Series H preferred stock through the
trustee of the share of Series Y preferred stock.

     Cumulative Voting.  The DGCL also provides that a certificate of
incorporation may allow cumulative voting for elections of directors of a
corporation or elections held under specified circumstances. Neither Broadbase's
nor Servicesoft's certificate of incorporation provide for cumulative voting.

STOCKHOLDER ACTIONS GENERALLY

     Under the bylaws of both Broadbase and Servicesoft, a majority of the
shares entitled to vote, present in person or represented by proxy, constitute a
quorum for the transaction of business at any meeting of stockholders. Please
also see "Action by written consent in lieu of a stockholders' meeting" below.

     Broadbase.  Broadbase's bylaws provide that, except for elections of
directors, stockholder actions generally require the affirmative vote of a
majority of the shares of stock entitled to vote on the matter that are present
in person or represented by proxy at the meeting and are voted for or against
the matter.

                                       103
<PAGE>   111

     Servicesoft.  Servicesoft's bylaws provide that stockholder actions, other
than elections of directors, generally require the affirmative vote of a
majority of the shares of stock entitled to vote on the matter that are present
in person or represented by proxy at the meeting and are voted on such matter,
except where a larger vote is required by law or by applicable law or
Servicesoft's certificate of incorporation.

SPECIAL MEETINGS OF STOCKHOLDERS

     Broadbase.  Broadbase's bylaws provide that special meetings of the
stockholders may be called at any time by the chairperson of the board of
directors, the chief executive officer, the president, or by a majority of the
members of the Board of Directors. Broadbase's bylaws require that special
meetings called by any person or persons other than by a majority of the members
of the board of directors be held not more than 120 nor fewer than 35 days after
a written request to call a special meeting was delivered to each member of the
board of directors.

     Servicesoft.  Servicesoft's bylaws provide that special meetings of the
stockholders may be called by the President or the Secretary at the request of
any two directors, stockholders owning 10% or more of Servicesoft's stock then
outstanding and entitled to vote, or by holders of 25% or more of Servicesoft's
preferred stock then outstanding and entitled to vote. Servicesoft's bylaws
require that the Secretary, an Assistant Secretary or other authorized person
give notice of a special meeting of the stockholders, stating the hour, date and
place of the meeting, as well as the purpose or purposes for which the meeting
has been called, to each stockholder entitled to vote at the meeting and to any
stockholder who, by law or under the certificate of incorporation or the bylaws
of Servicesoft, is otherwise entitled to notice. The notice must be given to the
stockholders not less than 10 days nor more than 60 days before the special
meeting.

ACTION BY WRITTEN CONSENT IN LIEU OF A STOCKHOLDERS' MEETING

     Broadbase.  Broadbase's certificate of incorporation provides that
stockholder actions may only be taken at annual or special meetings of
stockholders, and not by written consent.

     Servicesoft.  Section 228 of the DGCL provides that any action that is
permitted or required to be taken at any annual or special meeting of
stockholders may be taken without a meeting and without prior notice. Instead,
stockholders may take action by a written consent signed by the holders of at
least the number of shares that would be necessary to authorize the action at a
meeting at which all shares entitled to vote were present and voted.
Servicesoft's certificate of incorporation and bylaws do not restrict the
ability of Servicesoft stockholders to act by written consent.

VOTING BY WRITTEN BALLOT

     Broadbase.  Broadbase's bylaws provide that voting at meetings of
stockholders need not be by written ballot unless demanded by stockholders
holding shares representing at least 1% of the votes entitled to vote at the
meeting, or by such stockholders' proxy. However, an election of directors shall
be by written ballot if demanded by any stockholder at the meeting before voting
begins.

     Servicesoft.  Servicesoft's bylaws do not contain any provision requiring
written ballots.

RECORD DATE FOR DETERMINING STOCKHOLDERS

     Broadbase.  Broadbase's bylaws provide that the board of directors may fix
a record date which shall not be more than 60 nor less than 10 days before the
date of a stockholder meeting, nor more than 60 days prior to any other action.
If the board of directors does not fix a record date in the manner described
above, then:

     - the record date for determining stockholders entitled to notice of or to
       vote at a meeting of stockholders shall be the close of business on the
       day next preceding the day on which notice is given, or if notice is
       waived, at the close of business on the day next preceding the day on
       which the meeting is held; and

                                       104
<PAGE>   112

     - the record date for determining stockholders for any other purpose shall
       be at the close of business on the same day that the board of directors
       adopts the related resolution.

     Servicesoft.  Servicesoft's bylaws provide that the board of directors may
fix a record date for determining stockholders entitled to vote at a meeting of
the stockholders a date that is not more than sixty 60 nor more than 10 days
before the date of the meeting, and for any other action, a date that is not
more than 60 days prior to the other action. If the board does not fix a record
date in the manner described above, then, under the DGCL:

     - the record date for determining stockholders entitled to notice of or to
       vote at a meeting of stockholders shall be the close of business on the
       day next preceding the day on which notice is given, or, if notice is
       waived, at the close of business on the day next preceding the day on
       which the meeting is held; and

     - the record date for determining stockholders for any other purpose shall
       be at the close of business on same day that the board of directors

     Broadbase.  Broadbase's bylaws provide that written notice, stating the
place, date and time of the meeting, shall be delivered not less than 10 nor
more than 60 days before the date of the meeting to each stockholder of record
entitled to vote at such meeting.

     Nominations of persons for election to the board of directors and the
proposal of business to be considered by the stockholders at the annual meeting
may be made:

     - pursuant to Broadbase's notice of the meeting to each stockholder;

     - by or at the direction of the Broadbase board of directors; or

     If made by a Broadbase stockholder, the proposal or nomination must
generally be made by advance written notice given to the secretary of Broadbase
between 60 and 90 days before the first anniversary of the preceding year's
annual meeting of stockholders. However, if the date of the annual meeting at
which the nomination or business is proposed by a stockholder is more than 30
days before or more than 60 days after that anniversary, then the notice may be

REMOVAL OF DIRECTORS

     Broadbase.  Broadbase's certificate of incorporation and bylaws provide
that any director may be removed, with cause, by the holders of a majority of
the shares then entitled to vote at an election of directors, and without cause
by the same vote unless the votes cast against removal or not consenting in
writing to the removal would be sufficient to elect the director if voted
cumulatively.

     Servicesoft.  Servicesoft's bylaws provide that any director, or the entire
board of directors, may be removed, with or without cause, by the holders of a
majority of the shares entitled to vote at an election of directors.

BOARD OF DIRECTORS VACANCIES

that, subject to the rights of the holders of any series of preferred stock, any
vacancy occurring in the Broadbase board of directors for any reason, and any
newly created directorship resulting from any increase in the authorized number
of directors shall, unless Broadbase's board determines that those vacancies
shall be filled by its stockholders or as otherwise provided by law, be filled
by the vote of a majority of the directors then in office, even if less than a
quorum, or by a sole remaining director, and not by the stockholders.

     Servicesoft.  Servicesoft's bylaws provide that, subject to any rights of
holders of preferred stock to elect directors and fill vacancies on the board,
any and all vacancies on the board and newly created directorships will be
filled by the vote of a majority of the directors then in office, even if the
number of remaining directors constitutes less than a quorum. If there are no
directors then in office, an election of directors may be held in the manner
provided for by statute. If at any time the directors seeking to fill a vacancy
on the board do not constitute a majority of the board as determined prior to
stock increase, the applicable court, at the request of 10% of Servicesoft's
stockholders, may order an election.

NOTICE OF SPECIAL MEETINGS OF THE BOARD OF DIRECTORS

     Broadbase.  Broadbase's bylaws provide that special meetings of the board
may be called by the chairperson of the board, the president or a majority of
the members of the board then in office. Notice of the time, date and place of
such meeting shall be given, orally or in writing, by the person or persons
calling the meeting to all directors at least four days before the meeting if

quorum is present shall be the act of the board of directors. A majority of the
total number of authorized directors constitutes a quorum. Any action required
or permitted to be taken at any board meeting may be taken without a meeting if
all members of the board consent in writing.

     Servicesoft.  Servicesoft's bylaws provide that a majority of the directors

ACTION BY COMMITTEES

     Broadbase.  Broadbase's bylaws authorize the board of directors to
designate one or more committees, each committee to consist of one or more
directors of the corporation. The board of directors may authorize any committee
to have and exercise all powers and authority of the board of directors, except
that no committee shall have the power or authority to adopt, amend or repeal
Broadbase's bylaws, or approve or adopt, or recommend to Broadbase's
stockholders, any action expressly required under the DGCL to be approved by
Broadbase's stockholders.

membership one or more committees, and may delegate some or all of its powers to
those committees, except those powers that, by law or by its certificate of
incorporation or bylaws, cannot be delegated.

AMENDMENT OF CERTIFICATE OF INCORPORATION

     Broadbase and Servicesoft.  Section 242 of the DGCL authorizes a
corporation to amend its certificate of incorporation in any way so long as the
certificate as amended would only contain provisions lawful and proper for
insertion in an original certificate of incorporation. Section 242 of the DGCL
generally requires that, to amend a certificate of incorporation:

     - that corporation's board of directors must approve a resolution
       describing the proposed amendment;

     - a majority of the outstanding stock entitled to vote on the proposed
       amendment must approve the amendment at a special or annual meeting of
       that corporation's stockholders; and

     - a certificate setting forth the amendment and certifying that it has been
       duly adopted must be executed and filed with the Delaware secretary of
       state.

     Servicesoft.  In addition to the requirements of Delaware law, Servicesoft
must comply with the terms of a shareholders agreement to amend its certificate
of incorporation. Under the shareholders agreement, Servicesoft may not:

     - amend or repeal any provision of, or add any provision to, its
       certificate of incorporation that changes the voting powers, preferences
       or other special rights or privileges, or any restrictions, of any class
       of its preferred stock without obtaining the affirmative vote or written
       consent of the holders of more than 50% of the affected series, voting as
       a separate class; or

     - authorize or designate, whether by reclassification or otherwise, any new
       class or series of stock or any other securities convertible into equity
       securities that rank senior or evenly with any class of its preferred
       stock, without obtaining the affirmative vote or written consent of the
       holders of more than 50% of the affected series, voting as a separate
       class.

AMENDMENT OF BYLAWS

     Broadbase.  Broadbase's certificate of incorporation provides that the
board of directors has the power to adopt, amend or repeal the bylaws.
Broadbase's bylaws also provide that stockholders holding a majority of
Broadbase's outstanding voting stock then entitled to vote at an election of
directors may adopt, amend or repeal the bylaws.

     Servicesoft.  Servicesoft's bylaws provide that they may be amended by the
affirmative vote of a majority of the stockholders or by the board of directors
if it is empowered to do so by Servicesoft's certificate of incorporation.
Servicesoft's certificate of incorporation does not address the issue of
amending Servicesoft's bylaws.

     In addition to these requirements, Servicesoft must comply with the terms
of its shareholders agreement to amend its bylaws. Under the shareholders
agreement, Servicesoft may not amend or repeal any provision of, or add any
provision to, its bylaws that changes the voting powers, preferences or other
special rights or privileges, or any restrictions, of any class of its preferred
stock without obtaining the

                                       108
<PAGE>   116

affirmative vote or written consent of the holders of more than 50% of the
affected series, voting as a separate class.

LIMITATION OF DIRECTOR LIABILITY

     Broadbase.  Broadbase's certificate of incorporation provides that, to the
fullest extent permitted by law, a director of Broadbase will not be personally
liable for monetary damages for breach of fiduciary duty as a director.

     Servicesoft.  Servicesoft's certificate of incorporation provides that no
director will be personally liable to Servicesoft or its stockholders for
monetary damages for a breach of the director's fiduciary duty as a director.

     Broadbase and Servicesoft.  With respect to both Broadbase and Servicesoft,
the DGCL prohibits limitation of liability of directors for:

     - breaches of the director's duty of loyalty to the corporation or its
       stockholders;

     - acts or omissions by the director not in good faith or that involve
       intentional misconduct or a knowing violation of law;

     - any liability arising under Section 174 of the DGCL, which relates to
       unlawful payment of dividends or unlawful stock purchases or redemptions;
       and

     - any transaction from which the director derives an improper personal
       benefit.

INDEMNIFICATION

     Broadbase.  Broadbase's bylaws provide that its directors and officers
shall be indemnified to the fullest extent authorized by the DGCL. This
indemnification shall apply to all expenses, liabilities and losses reasonably
incurred in connection with any action, proceeding or suit brought against that
person by reason of the fact that he or she is or was a director or officer of
Broadbase, provided such person acted in good faith and in a manner which the
person reasonably believed to be in or not opposed to the best interest of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe the person's conduct was unlawful. Broadbase's
bylaws require Broadbase to pay all expenses incurred by a director or officer
in defending any proceeding described above as these expenses are incurred in
advance of the final disposition of the proceeding. However, Broadbase's bylaws
do not require Broadbase to advance any expenses to a person against whom
Broadbase directly brings a claim alleging that that person breached a duty of
loyalty to Broadbase, committed an act or omission not in good faith or that
involves intentional misconduct or a knowing violation of law, or derived an
improper benefit from a transaction.

     Broadbase's bylaws also authorize the Broadbase board of directors to
authorize Broadbase to enter into indemnification contracts with its directors,
officers and employees, or anyone serving in such capacity with another
enterprise at Broadbase's request, with rights that may be broader than those
described above with regard to Broadbase's bylaws.

     Servicesoft.  Servicesoft's bylaws provide that its directors and officers
shall be indemnified to the fullest extent authorized by the DGCL. This
indemnification applies to all reasonable expenses, liabilities and losses
incurred in connection with the director's status as a director Servicesoft,
acting in his or her capacity as a director, provided the director acted in good
faith and in a manner he or she reasonably believed to be in or not opposed to
the best interest of Servicesoft, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful. Servicesoft will advance all expenses incurred by or on behalf of any
director in connection with any proceeding in which the director is involved by
reason of the director's corporate status following the receipt by Servicesoft
of a written statement from the director requesting the advance.

                                       109
<PAGE>   117

     Servicesoft's bylaws also provide that the indemnification provisions will
be deemed to be a contract between Servicesoft and each director entitled to the
benefits of those provisions at any time while the indemnification provisions
are in effect. They specify that any repeal or modification of the bylaw
provisions relating to indemnification will not affect any rights or obligations
then existing with respect to indemnification obligations existing at or prior
to that repeal or modification.

     Broadbase and Servicesoft.  Section 145 of the DGCL generally provides for
broad indemnification of a director or officer if that person acted in good
faith and in a manner the person reasonably believed to be in the best interests
of the corporation. We urge you to refer to Section 145 of the DGCL for further
detail.

INTERESTED DIRECTORS

     Broadbase and Servicesoft.  Section 144 of the DGCL and Broadbase's bylaws
provide that a transaction between either corporation and an interested director
will not be void or voidable solely for this reason if:

     - the material facts as to the interested director's relationship or
       interest to the transaction are disclosed to or known by the directors,
       and a majority of the disinterested directors present at the meeting vote
       in good faith in favor of the transaction, even if the disinterested
       directors do not constitute a quorum;

     - the material facts as to the interested director's relationship or
       interest to the transaction are disclosed to or known by the
       stockholders, and the stockholders vote in good faith in favor of the
       transaction; or

     - the transaction is fair to Broadbase as of the time it is authorized,
       approved or ratified by the board of directors, a committee of the board
       or the stockholders.

     Interested directors may be counted in determining the presence of a quorum
at a meeting of the board or of a committee which authorizes the contract or
transaction.

AUTHORIZED CAPITAL STOCK

     Broadbase.  Broadbase's certificate of incorporation currently authorizes
Broadbase to issue 95,000,000 shares, all of which have a par value of $0.001
per share, consisting of two classes: 90,000,000 shares of common stock and
5,000,000 shares of preferred stock. Broadbase's First Amended and Restated
Certificate of Incorporation, if approved by Broadbase's stockholders, will
authorize Broadbase to issue 355,000,000 shares, consisting of 350,000,000
shares of common stock and 5,000,000 shares of preferred stock.

     In addition, Broadbase's board of directors is authorized to provide for
the issuance of the shares of preferred stock in one or more series, and, by
filing a certificate of designation pursuant to the applicable law of the State
of Delaware, to establish from time to time the number of shares to be included
in each such series, to fix the designation, powers, preferences and rights of
the shares of each such series and any qualifications, limitations or
restrictions thereof, and to increase or decrease the number of shares of any
such series.

     Servicesoft.  Servicesoft's certificate of incorporation authorizes
Servicesoft to issue 46,450,002 shares of all classes of stock, all of which
have a par value of $0.01 per share, consisting of 30,000,000 shares of common
stock and 16,450,002 shares of preferred stock. There are five series of
Servicesoft preferred stock. The first series consists of 8,000,000 shares and
is designated Series H preferred stock. The second series consists of 4,450,000
shares and is designated Series I preferred stock. The third series consists of
4,000,000 shares and is designated Series J preferred stock. The fourth series
consists of one share of Series X Special Preferred Voting Stock. The fifth
series consists of one share of Series Y Special Preferred Voting Stock.

                                       110
<PAGE>   118

CONVERSION RIGHTS

     Broadbase.  Broadbase has not authorized or issued any shares of capital
stock that are convertible into or exchangeable for its common stock.

     Servicesoft.  Any shares of Servicesoft's preferred stock (other than
shares of its Series X Special Preferred Voting Stock and Series Y Special
Preferred Voting Stock) are convertible into common stock at the option of the
holder. All unconverted outstanding preferred stock is automatically converted
into common stock upon the earlier of:

     - the affirmative vote of the holders of a majority of at least two-thirds
       of the shares of preferred stock then outstanding (including the holders
       of Servicesoft Canada's exchangeable preferred stock voting as described
       under "Votes per share" above) and, with respect to conversion of each of
       the Series I and Series J preferred stock, the affirmative vote of the
       holders of at least two-thirds of the Series I and Series J preferred
       stock then outstanding, each voting as a separate series; and

     - the effectiveness of a firm commitment underwritten public offering of
       Servicesoft's securities pursuant to an effective registration statement
       under the federal securities laws, with aggregate gross proceeds to
       Servicesoft of not less than $30,000,000, where Servicesoft is valued at
       not less than $250,000,0000.

     Each share of any series of Servicesoft's Series H, I and J preferred stock
is initially convertible into one share of Servicesoft common stock. The
conversion ratio is subject to proportional adjustment for stock splits and
combinations, stock dividends, reclassifications and reorganizations.

     In addition, the conversion ratio for a given series of Servicesoft's
preferred stock is subject to adjustment if, after the date its certificate of
incorporation was filed, Servicesoft sells or is deemed to sell additional
shares of its common stock at price that is lower than the original issue price
for that series of preferred stock. Servicesoft will be deemed to have sold
additional shares of its common stock for less than the original issue price of
a series of preferred stock if, for example, it issues other securities that are
convertible into common stock at an exercise price that is lower than the
original issue price.

     The conversion ratio is equal to the quotient of the original issue price
for a series of preferred stock and the conversion value, which is initially
equal to the original issue price. If the corporation issues additional shares
of its common stock at a price that is lower that the original issue price, then
the conversion value is reduced, thereby increasing the number of shares of
common stock issuable upon conversion of that series of preferred stock.

     Certain issuances of common stock at a price lower than the original issue
price of any series of preferred stock do not trigger this price-based
anti-dilution protection. These include shares of common stock:

     - issued or issuable upon conversion of shares of Servicesoft's preferred
       stock or Servicesoft Canada's exchangeable common stock or exchangeable
       preferred stock;

     - issued or issuable to officers, employees, directors or consultants of
       Servicesoft pursuant to Servicesoft's stock option and grant plans
       approved by its board of directors where the approval includes a majority
       of members of the board who are not employees of Servicesoft;

     - issued or issuable upon exercise of warrants to purchase shares of common
       stock outstanding as of the date of the filing of Servicesoft's
       certificate of incorporation; and

     - issued as a dividend or distribution in preferred stock pursuant to stock
       splits and combinations, stock dividends, reclassifications and
       reorganizations.

DIVIDENDS

     Broadbase.  According to Section 154 of the DGCL, Broadbase stockholders
are entitled to receive dividends, subject to preferences of any outstanding
preferred stock, out of assets legally available for

                                       111
<PAGE>   119

dividend distribution at such times and in such amounts as the board of
directors may from time to time determine. Under Section 170 of the DGCL,
Broadbase's board of directors may declare and pay dividends out of surplus or
out of net profits for the current and/or preceding fiscal year as long as the
dividends will not reduce capital below the total amount of capital represented
by the issued and outstanding stock of all classes having a preference on the
distribution of assets. In addition, under the DGCL, a corporation may generally
redeem or repurchase shares of its stock if the redemption or repurchase will
not impair the capital of the corporation.

     Servicesoft.  In addition to the provisions of the DGCL relating to
dividends described above, Servicesoft is subject to the requirements of its
certificate of incorporation, which provides that, subject to any preferences of
holders of Servicesoft's preferred stock, the holders of common stock shall be
entitled to receive dividends out of funds legally available for dividend
distribution at such times and in such amounts as Servicesoft's board of
directors may from time to time determine.

     Holders of Servicesoft's preferred stock, prior and in preference to the
holders of its common stock, are entitled to receive, when, as and if declared
by the board of directors, non-cumulative cash dividends at the rate of 6% per
year on the original issue prices of each outstanding share of preferred stock
held by such holder. The original issue price of the Series H preferred stock is
$2.53 per share, the original issue price of the Series I preferred stock is
$4.10 per share and the original issue price of the Series J preferred stock is
$9.03 per share. After the holders of preferred stock have been paid the 6%
dividend preference, then any further dividends paid to the common stockholders
must also be paid to the preferred stockholders as if they had converted their
preferred stock to common stock.

     If the board pays or sets aside dividends for the holders of the preferred
stock in an amount less than the aggregate dividends payable at the preferred
dividend rate, then the amount to be paid or declared and set apart for payment
is divided between the holders of the Series H, Series I, and Series J preferred
stock, ratably in the same proportion such holders would have received had the
full amount of the dividends been declared and paid.

REDEMPTION

     Broadbase.  Broadbase's charter documents do not provide for redemption
rights, and Broadbase is not a party to any agreement that provides these rights
to stockholders.

     Servicesoft.  To the extent permitted by Delaware law, Servicesoft's Series
H preferred stock is redeemable by Servicesoft upon the affirmative vote of the
holders of a majority of shares of the Series H preferred stock, on each of
February 10, 2004, February 10, 2005 and February 10, 2006, on each such
redemption date with respect to a number of shares equal to one-third of the
outstanding shares of Series H preferred stock outstanding on the first
redemption date.

     To the extent permitted by Delaware law, Servicesoft's Series I and Series
J preferred stock is redeemable by Servicesoft, at the option of a holder of any
such shares on each of February 10, 2004, February 10, 2005 and February 10,
2006, on each such redemption date with respect to a number of shares equal to
one-third of the outstanding shares of Series I and Series J preferred stock
outstanding, respectively, on the first redemption date.

     Servicesoft is required to redeem the shares in cash equal to the same
amount per share as would be payable if there were to be a liquidation event,
plus 10% per annum "redemption value," compounded on each redemption date, plus
any declared and unpaid dividends with respect to the shares.

LIQUIDATION

     Broadbase.  In the event of liquidation, dissolution or winding up of
Broadbase, after payment of any amounts owed to creditors, subject to
preferences of any outstanding preferred stock, the remaining assets of
Broadbase will be divided equally, on a share for share basis, to the holders of
the common stock of Broadbase.

                                       112
<PAGE>   120

     Servicesoft.  In the event of a liquidation event, as defined below, after
payment of any amounts owed to creditors, the holders of Servicesoft's preferred
stock are entitled to receive a preferential payment, prior and in preference to
holders of its common stock. The holders of Servicesoft's Series H preferred
stock share an aggregate liquidation preference of $19,203,186. The per-share
liquidation preference for the holders of Series I and Series J preferred stock
is equal to the original issue price per share for each of those series ($4.10
for the Series I preferred stock and $9.03 for the Series J preferred stock).
Holders of Servicesoft Canada's exchangeable preferred stock participate with
the holders of Servicesoft's Series H preferred stock in receiving the Series H
liquidation preference. If Servicesoft's assets are insufficient to permit
payment of the full liquidation preferences of the preferred stockholders, then
the existing assets are to be distributed ratably among the preferred
stockholders in proportion to the preference amounts each holder would otherwise
be entitled to receive.

     After the preferred stock has received its liquidation preference, then
holders of Servicesoft common stock, which for purposes of the liquidation
preference includes Servicesoft Canada exchangeable common stock, will be
entitled to receive an amount per share equal to the liquidation preference of
the Series H preferred stock. Thereafter, further amounts must be paid in
accordance with the following distribution scheme:

     - the holders of common stock, and the holders of Series H preferred stock
       who have received the same per-share distribution as the common stock,
       will be entitled to receive an amount per share equal to the difference
       between the amount already received by them and the amount received by
       the holders of Series H preferred stock who received the next highest
       per-share amount (from any other series of preferred stock that they
       hold); then

     - the holders of common stock and Series H preferred stock, together with
       those holders of Series H preferred stock who have received the same
       per-share distribution as the common stock, will be entitled to receive
       an amount per share equal to the difference between the amount already
       received by them and the maximum per-share amount already paid to holders
       of Series H preferred stock; then

     - the holders of common stock and Series H preferred stock will be entitled
       to receive an amount per share equal to the difference between the amount
       already received by them and the maximum per share amount paid to holders
       of Series I preferred stock; then

     - the holders of common stock, the Series H and the Series I preferred
       stock will be entitled to receive an amount per share equal to the
       difference between the amount already received by them and the maximum
       per share amount paid to holders of Series J preferred stock; then

     - the holders of Series H, Series I and Series J preferred stock and common
       stock will be entitled to participate pro rata on an as-converted basis
       in the distribution of any remaining Servicesoft assets.

     A liquidation event is defined to include:

     - an involuntary or voluntary liquidation;

     - any sale of all or substantially all the assets of Servicesoft; or

     - the acquisition of Servicesoft by another entity in which the
       stockholders of Servicesoft immediately prior to the transaction own less
       than 50% of the corporation's voting power immediately after that
       transaction or any transaction or series of related transactions to which
       Servicesoft is a party in which the excess of 50% of the voting power of
       Servicesoft is transferred, except for reincorporations.

PREEMPTIVE AND CO-SALE RIGHTS AND RIGHTS OF FIRST REFUSAL

     Broadbase.  Broadbase's certificate of incorporation and bylaws do not
provide for preemptive rights, co-sale rights or rights of first refusal, and
Broadbase is not a party to any agreements which provide for these rights to
stockholders generally.

                                       113
<PAGE>   121

     Servicesoft.  Servicesoft's certificate of incorporation provides that if
at any time a holder of its common stock or preferred stock, with the exception
of holders of Series I or Series J preferred stock, desires to sell or transfer
part or all of its shares to another person, the holder will first submit an
offer to Servicesoft to sell the shares, and Servicesoft has the opportunity to
purchase the shares on the same terms as the proposed transfer. Also, under a
shareholders agreement, holders of Servicesoft's preferred stock have
pre-emptive rights with respect to new securities issued by Servicesoft, co-sale
rights and rights of first refusal if certain Servicesoft stockholders seek to
transfer their stock to a third party, and rights to receive financial
statements and reports of Servicesoft.

CORPORATE LAW RELATING TO ACQUISITIONS AND BUSINESS COMBINATIONS

     Broadbase.  Because Broadbase's certificate of incorporation and bylaws do
not contain a provision expressly electing for Broadbase not to be governed by
Section 203 of the DGCL, Broadbase is subject to the Delaware takeover statute.
Section 203 of the DGCL prohibits a Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for 3 years following
the date that the person becomes an interested stockholder.

     Business combination is defined broadly to include mergers with or caused
by the interested stockholder, sales or other dispositions made
disproportionately to the interested stockholder and other transactions. With
some exceptions, an interested stockholder is a person or group that owns 15% or
more of the corporation's outstanding voting stock, including rights to acquire
stock, or is an affiliate or associate of the corporation and was the owner of
15% or more of the corporation's voting stock at any time within the previous
three years.

     The three-year moratorium imposed on business combinations by Section 203
does not apply if:

     - before the person becomes an interested stockholder the board of
       directors approves either the business combination or the transaction
       resulting in the person becoming an interested stockholder;

     - the interested stockholder owns 85% of the corporation's voting stock
       upon completion of the transaction resulting in the person becoming an
       interested stockholder; or

     - on or after the date the person becomes an interested stockholder, the
       business combination is approved by the board and at a stockholders
       meeting by holders of 66 2/3% of the voting stock not owned by the
       interested stockholder.

     Servicesoft.  Because Section 203 of the DGCL also does not apply to
corporations that do not have a class of voting stock that is listed on a
national securities exchange, authorized for quotation on the Nasdaq National
Market or held of record by more than 2,000 stockholders, Servicesoft is not
subject to the Delaware takeover statute.

VOTE REQUIRED TO APPROVE MERGERS, ACQUISITIONS AND OTHER TRANSACTIONS

     Broadbase.  Section 251 of the DGCL generally provides that an agreement of
merger or consolidation requires the affirmative vote of a majority of the board
of directors present at the board meeting and a majority of the outstanding
shares of stock entitled to vote on the merger. This section also defines
several exceptions where stockholder approval is not required. For example, the
DGCL does not require a stockholder vote of the surviving corporation in a
merger, unless the corporation provides otherwise in its certificate of
incorporation, if:

     - the merger agreement does not amend the existing certificate of
       incorporation;

     - each share of the corporation outstanding before the merger is an
       identical outstanding or treasury share of the surviving corporation
       after the merger; and

     - the number of shares to be issued by the surviving corporation in the
       merger does not exceed 20% of the shares of that corporation outstanding
       immediately before the merger.

                                       114
<PAGE>   122

     Similarly, Section 271 of the DGCL generally provides that a corporation
may dispose of all or substantially all of its assets with the vote of a
majority of the board of directors present at the board meeting and a majority
of the outstanding shares of stock entitled to vote on the transaction.

     Servicesoft.  Servicesoft is subject to the voting requirements of the
DGCL. In addition, Servicesoft has entered into a shareholders agreement which
provides that, so long as any shares of its Series H, Series I or Series J
preferred stock are outstanding, Servicesoft will not, without first obtaining
the affirmative vote or written consent of more than 50% of the outstanding
shares of these series and the outstanding shares of exchangeable preferred
stock of Servicesoft Canada, preferred stock with all these series voting
together as a single class:

     - consolidate or merge into or with any other entity or entities (except a
       consolidation or merger in which the beneficial owners of Servicesoft's
       capital stock immediately prior the transaction continue to hold 51% or
       more of the voting power in the resulting entity);

     - sell, mortgage or transfer all or substantially all of Servicesoft's
       assets;

     - enter into any other transaction or series of transactions that would
       result in a transfer of all or substantially all of its assets; or

     - permit any subsidiary to engage in such a transaction or series of
       transactions.

APPRAISAL AND DISSENTERS' RIGHTS

     Broadbase.  As described below, Section 262 of the DGCL generally provides
for appraisal rights in connection with merger or consolidation transactions.
However, no appraisal rights are available for:

     - shares of stock of the surviving corporation if approval of the
       stockholders of the surviving corporation was not required by the DGCL;
       or

     - shares of stock that, as of the record date for the stockholder vote on
       the merger-related proposals, are either:

        -- listed on a national securities exchange,

        -- designated as a national market system security on an interdealer
           quotation system by the National Association of Securities Dealers,
           Inc., or

        -- held of record by more than 2,000 holders;

unless the agreement of merger or consolidation provides that stockholders will
receive consideration other than cash in lieu of fractional shares, stock of the
surviving corporation, stock of another corporation which meets at least one of
the three criteria listed above, or any combination of these three forms of
consideration.

     So long as Broadbase common stock is quoted on the Nasdaq National Market,
appraisal rights will not be available for Broadbase stockholders in a merger or
consolidation transaction unless the associated merger agreement provides that
stockholders will receive consideration other than the forms of consideration
listed in the preceding paragraph.

     Servicesoft.  Section 262 of the DGCL provides that a stockholder of a
corporation involved in a merger or consolidation may be entitled to an
appraisal by the Court of Chancery of the fair value of the stockholder's shares
if the requirements for eligibility described in this section are satisfied. For
a description of the eligibility requirements and procedural requirements
associated with perfecting appraisal rights, see "Appraisal Rights" beginning on
page 145 and Annex H of this document.

STOCKHOLDER RIGHTS PLAN

     Neither Broadbase nor Servicesoft has adopted a stockholder rights plan.

                                       115
<PAGE>   123

                               SHARE OWNERSHIP BY
                       PRINCIPAL STOCKHOLDERS, MANAGEMENT
                           AND DIRECTORS OF BROADBASE

     The following table sets forth information concerning the beneficial
ownership of common stock of Broadbase as of September 30, 2000 for:

     - each person or entity who is known by Broadbase to own beneficially more
       than 5% of the outstanding shares of Broadbase common stock;

     - Broadbase's Chief Executive Officer and each of Broadbase's four other
       most highly compensated executive officers during 1999;

     - each of Broadbase's current directors; and

     - all directors and executive officers of Broadbase as a group.

     The pre-merger percentage ownership is based on 50,466,772 shares of
Broadbase common stock outstanding as of September 30, 2000. The post-merger
percentage ownership is based on 79,429,658 shares to be outstanding after the
merger. This figure is an estimate derived by assuming that all shares of
Servicesoft Canada stock has been exchanged for Servicesoft stock, and all
shares of Servicesoft preferred stock, other than Series X and Series Y
preferred stock, outstanding as of September 30, 2000 had been converted into
Servicesoft common stock as of this date, and then applying the 1.4404 exchange
ratio to the 20,107,530 aggregate shares of Servicesoft common stock outstanding
as of this date.

     All shares subject to options and warrants exercisable on or before
November 29, 2000, or within 60 days after September 30, 2000, are deemed to be
beneficially owned by the person or entity holding such options or warrants and
to be outstanding solely for calculating such person's or entity's percentage
ownership. Unless otherwise indicated below, the address of each director and
executive officer listed below is Broadbase Software, Inc., 181 Constitution

     Fifty percent of the unvested Servicesoft options or shares of restricted
Servicesoft stock held by Ms. Forest, Mr. Davoli, Mr. Skapinker, Mr. Greendale
and Mr. Rubinoff will vest upon the closing of the merger. Mr. Kossmann entered
into an employment agreement with Broadbase which provides that the unvested
portion of Mr. Kossmann's option to purchase 180,000 shares of Servicesoft
common stock will vest upon the closing of the merger. In addition, the vesting
of Mr. Zarrabian's Servicesoft stock options will accelerate in connection with
the merger as described in the section of this document entitled "Related Party
Transactions" beginning on page 123.

                           RELATED PARTY TRANSACTIONS

     This section describes some agreements and arrangements between Broadbase
and its directors and executive officers. This is not an exhaustive list.
Descriptions of additional agreements and arrangements are incorporated into
this document by reference to definitive proxy statement for the 2000 annual
meeting of Broadbase stockholders.

BROADBASE TRANSACTIONS

  Offer letters and stock option grants

     In May 2000, Broadbase granted to each of its non-employee directors an
option to purchase 20,000 shares of Broadbase common stock at an exercise price
of $20.81 per share. Each option was fully vested and exercisable upon grant.

     In May 2000, Broadbase granted to Chris Maeda, Executive Vice President and
Chief Technical Officer, an option to purchase 100,000 shares of Broadbase
common stock at an exercise price of $1.00. This option vests as to 4,166 shares
each month over two years. In addition, Broadbase granted to Rusty Thomas,
Executive Vice President and Chief Financial Officer, an option to purchase
100,000 shares of Broadbase common stock at an exercise price of $1.00. This
option vests as to 2,083 shares each month over four years, subject to full
acceleration should Broadbase be acquired by another company and Mr. Thomas is
not retained in the role of Chief Financial Officer.

     Fabio Angelillis' offer letter for the position of Executive Vice
President, Engineering, dated August 21, 2000, provides for an initial annual
base salary of $200,000 and bonuses of up to $40,000 per year. In September
2000, Broadbase granted Mr. Angelillis an option to purchase 268,000 shares of
Broadbase common stock at an exercise price of $17.94 per share. This option
will vest as to 16,750 shares in December 2000, and as to 5,583 shares each
month thereafter. Also in September 2000, Broadbase granted Mr. Angelillis an
option to purchase 132,000 shares of Broadbase common stock at an exercise price
of $1.00 per share. This option vests as to 2,750 shares each month over four
years. The offer letter provides that Broadbase will provide Mr. Angelillis with
its standard health, holiday, vacation, 401(k) and other benefits. Mr.
Angelillis' employment is considered an "at-will" agreement. Broadbase or Mr.
Angelillis may terminate the employment relationship at any time for any reason.

     In October 2000, Broadbase granted an option to purchase 100,000 shares of
Broadbase common stock at an exerice price of $11.375 to each Tom Doyle,
Executive Vice President and Chief Operating Officer, and Brian Kelly, Executive
Vice President Product Strategy. These options each vest as to 2,083 shares each
month over four years. In addition, Broadbase granted an option to purchase
50,000 shares of Broadbase common stock at an exercise price of $11.375 to each
Rusty Thomas and David Milam, Executive Vice President of Marketing. These
options each vest as to 1,042 shares each month over four years.

     Massood Zarrabian, Chief Executive Officer and President of Servicesoft,
entered into an employment agreement with Broadbase on September 18, 2000. The
agreement provides that, upon the closing of the merger, Mr. Zarrabian will
become an employee of Broadbase and will receive a salary of $200,000 per year,
with bonuses of up to $60,000 per year. Also, under the agreement, Broadbase
will assume Mr. Zarrabian's three Servicesoft stock options, discussed below,
which, at the conversion rate of 1.4404 will become options to purchase an
aggregate of 878,644 shares of Broadbase common stock. Under the employment
agreement, 50% of the unvested portion of one of Mr. Zarrabian's options,
originally for 430,000 shares of Servicesoft common stock, which at the
conversion rate equals 619,372 shares of Broadbase common stock, will become
vested as of the closing of the merger and any remaining shares will vest
ratably over two years. That option is immediately exercisable, but the
underlying shares, once issued, remain subject to vesting and a right of
repurchase. If within two years of the closing of the merger Mr. Zarrabian is
terminated by Broadbase without cause or is effectively terminated because of a
change in the terms of his employment, then Mr. Zarrabian will receive one year
of salary, plus bonuses, payable

                                       122
<PAGE>   130

in one lump sum and any unvested shares under the option to purchase 619,372
shares plus 50% of any unvested shares subject to Mr. Zarrabian's other options
will become vested.

SERVICESOFT TRANSACTIONS

  Offer letters and stock option grants

     Massood Zarrabian's offer letter from Servicesoft, dated June 9, 1999,
provides for an initial annual salary of $180,000, which has since been
increased to $200,000. Upon the closing of the merger, Mr. Zarrabian's
employment agreement with Broadbase described above will supersede this offer
letter. In August 1999, Mr. Zarrabian was granted an option to purchase 120,000
shares of Servicesoft common stock at an exercise price of $0.50 per share. This
option vested as to 30,000 shares in August 1999, and vests as to 2,500 shares
per month thereafter. In December 1999, Mr. Zarrabian was granted an option to
purchase 60,000 shares of Servicesoft common stock at an exercise price of $1.00
per share. This option vested as to 16,800 shares in June 2000, and vests as to
1,200 shares each month thereafter. In July 2000, Mr. Zarrabian was granted an
option to purchase 430,000 shares of Servicesoft common stock at an exercise
price of $14.00 per share. Each of these options were assumed by Broadbase in
connection with the merger on the terms described above.

     In November 1999, Servicesoft sold 25,000 shares of its common stock to
Robert E. Davoli, a director of Servicesoft, for $1.00 per share. These shares
are subject to a right of repurchase that lapses as to 2,063 shares each
quarter. Upon the closing of the merger, 50% of Mr. Davoli's unvested shares
will become vested.

  Preferred stock financings

     In February 1998, Servicesoft raised capital to finance its operations
through the sale of an aggregate of 4,667,969 shares of its Series G preferred
stock to various investors for $5,975,000, or $1.28 per share. Entities
affiliated with Sigma Partners purchased an aggregate of 1,562,500 shares for an
aggregate purchase price of $2,000,000. Mr. Davoli is the Managing Director of
the general partner of each of these entities. In connection with Servicesoft's
acquisition of Balisoft in February 1999, each share of Series G preferred stock
was converted into 0.53781 shares of Series H preferred stock.

     In June and August 1999, Servicesoft issued an aggregate of 3,982,271
shares of Series I convertible preferred stock for $16,327,310, or $4.10 per
share. Entities affiliated with Sigma Partners purchased an aggregate of 123,825
shares for a purchase price of $507,683.

     In January 2000, Servicesoft issued an aggregate of 3,481,478 shares of its
Series J preferred stock for an aggregate of $31,437,989, or $9.03 per share.
Entities affiliated with Sigma Partners purchased an aggregate of 385,271 shares
for an aggregate purchase price of $3,478,997. Also in this financing, Mr.
Zarrabian purchased 22,148 shares of Series J preferred stock for an aggregate
purchase price of $199,996.

  Director representation

     Robert E. Davoli, currently a Servicesoft director, will serve on the board
of directors of the combined company. Mr. Davoli also served on the board of
directors of Internet Business Advantages, which was acquired by Servicesoft in
December 1999. He is a General Partner of Sigma Partners, whose affiliated
entities hold Servicesoft's Series I and J preferred stock.

               SERVICESOFT'S SELECTED CONSOLIDATED FINANCIAL DATA

     The following selected consolidated financial data should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and Servicesoft's consolidated financial statements
and related notes included elsewhere in this document. The statement of
operations data for the years ended December 31, 1997, 1998 and 1999 and the
balance sheet data as of December 31, 1998 and 1999 are derived from
Servicesoft's audited consolidated financial statements appearing elsewhere in
this document. The statement of operations data for the years ended December 31,
1995 and 1996 and the balance sheet data as of December 31, 1995, 1996 and 1997
are derived from Servicesoft's audited consolidated financial statements not
included in this document.

     The statement of operations data for the six-month periods ended June 30,
1999 and 2000 and the balance sheet data as of June 30, 2000 are derived from
Servicesoft's unaudited interim consolidated financial statements. The unaudited
interim financial statements have been prepared on the same basis as
Servicesoft's audited financial statements and, in Servicesoft's opinion,
include all adjustments, consisting only of normal recurring adjustments, which
Servicesoft considers necessary for a fair presentation of its results of
operations and financial position for these periods. There is no difference
between historical basic and diluted net loss per common share since potential
common shares from the conversion of preferred stock and the exercise of options
and warrants are anti-dilutive for all periods presented. Historical results are
not necessarily indicative of future results.

     Servicesoft's results for the year ended December 31, 1999 reflect the
February 12, 1999 merger with Balisoft and the December 17, 1999 acquisition of
Internet Business Advantages which were accounted for using the purchase method.
Accordingly, the results of operations of Balisoft and Internet Business
Advantages are included in Servicesoft's results from the applicable closing
dates. Since the merger with Balisoft and the acquisition of Internet Business
Advantages were completed in 1999, the effects of these transactions are
reflected in the balance sheet data as of December 31, 1999.

              SERVICESOFT MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     This document contains forward-looking statements that involve risks and
uncertainties. Actual results may differ materially from those indicated in such
forward-looking statements. See "Cautionary Note Concerning Forward-Looking
Statements" on page 151.

OVERVIEW

     Servicesoft develops, markets and delivers software products and
professional services that help businesses provide superior e-service to their
customers, employees and business partners. Servicesoft licenses its software
products to clients across a variety of industries, including
telecommunications, e-commerce, financial services, technology, manufacturing
and healthcare.

     Servicesoft derives its revenue from three sources: the sale of software
licenses, implementation assistance and other professional services and software
maintenance services. Servicesoft plans to generate future revenue from both
existing and new clients. As existing clients either expand their usage or
implement new Servicesoft products, they may be required to pay additional
license fees under existing license agreements or license additional copies of
Servicesoft software. Servicesoft recognizes software license fees and
implementation assistance fees on a percentage of completion basis when it
assists its clients in implementing its products, there is evidence of a binding
arrangement, the fees are fixed or determinable and collection is probable. If
Servicesoft is not implementing its software solution, it recognizes software
license fees when the software is delivered to the end user, so long as the fees
are fixed or determinable, there is evidence of a binding arrangement and
collection is probable. Professional services other than implementation
assistance or maintenance services are contracted for on either a time-
and-materials or fixed-price basis. Servicesoft recognizes service fees
contracted for on a time-and-materials basis as the services are performed.
Servicesoft recognizes service fees contracted for on a fixed-price basis on an
estimated percentage of completion as work progresses. Clients purchasing
maintenance services receive unspecified product upgrades on a when- and
if-available basis and unlimited e-service and telephone technical support.
Servicesoft's clients typically purchase maintenance services annually, and
Servicesoft prices maintenance services based on a fixed percentage of its
current product list price. Servicesoft recognizes revenue on maintenance
services ratably over the term of the period covered, typically one year, and
records cash receipts and contracted amounts due from clients in excess of
revenue recognized as deferred revenue. The timing and amount of cash receipts
from clients can vary significantly depending on specific contract terms and can
therefore have a significant impact on the amounts of receivables due or
deferred revenue in any given period.

     Servicesoft's cost of software license revenue includes royalties due to
third parties for technology included in Servicesoft's products, the cost of
manuals and product documentation, media used to deliver products, shipping and
fulfillment costs. Servicesoft's cost of services revenue includes salaries and
related costs for its consulting and support organizations and costs of third
parties contracted to provide consulting services to its clients.

     Servicesoft's operating expenses are classified as sales and marketing,
research and development, general and administrative, amortization of goodwill
and other intangible assets and stock compensation expense for issuance of and
modification to stock options and restricted stock. Sales and marketing expenses
consist primarily of salaries and other related costs for sales and marketing
personnel, sales commissions, travel, public relations, advertising, promotional
materials and tradeshows. Research and development expenses consist primarily of
salaries and related costs for product development personnel and for consulting
fees to support product development. To date, Servicesoft has not capitalized
any research and development costs. General and administrative expenses consist
primarily of salaries and other related costs for finance, human resources,
internal systems and other administrative employees, legal and accounting fees
and insurance premiums. Stock compensation expenses for the issuance of stock
options and restricted stock represent the difference between the exercise price
or purchase price of options or

                                       126
<PAGE>   134

restricted stock granted and the estimated fair market value for financial
reporting purposes of the common stock on the date of the grant or modification.

     Over the past several years, Servicesoft has incurred substantial costs to
develop and acquire its technology and products, to recruit and train personnel
for engineering, sales, marketing and professional services departments and to
establish an administrative organization. As a result, the company has incurred
significant losses during this period and, as of June 30, 2000, it had an
accumulated deficit of $89.8 million. Servicesoft believes that its success
depends on increasing its client base and on the emerging e-service market.
Accordingly, Servicesoft intends to continue to invest heavily in sales,
marketing, professional services, research and development and in its
operational and financial systems. Furthermore, Servicesoft expects to continue
to incur substantial operating losses at least through 2001, and the increase in
operating expenses will require a significant increase in revenue before
Servicesoft becomes profitable.

     Servicesoft had 312 full-time employees at September 30, 2000, up from 118
at September 30, 1999. This rapid growth places a significant demand on
Servicesoft's management and operational resources. In order to manage growth
effectively, Servicesoft must implement and improve its operational systems,
procedures and controls on a timely basis. In addition, Servicesoft expects that
future expansion will continue to challenge its ability to hire, train, motivate
and manage its employees. Competition is intense for highly qualified technical,
sales, marketing, administrative and management personnel. If Servicesoft's
revenue does not increase relative to the company's operating expenses, its
management systems do not expand to meet increasing demands, it fails to
attract, assimilate and retain qualified personnel or its management otherwise
fails to manage the company's expansion effectively, there would be a material
adverse effect on Servicesoft's business, operating results and financial
condition.

     In February 1999, Servicesoft merged with Balisoft, a developer of e-mail
management and real-time Internet collaboration applications, in exchange for
2.2 million shares of exchangeable common stock and 2.3 million shares of
exchangeable preferred stock; Servicesoft also assumed or issued employee stock
options and warrants to purchase approximately 641,000 shares of its common
stock. The total cost of the merger, including transaction costs, was $12.6
million. Servicesoft accounted for the merger as a purchase business
combination. Accordingly, the results of operations of Balisoft have been
included with the results of operations for Servicesoft for periods subsequent
to the date of the merger and the acquired net assets were recorded at their
estimated fair values at the effective date of the merger, resulting in $8.6
million recorded as goodwill and other intangibles.

     In December 1999, Servicesoft acquired Internet Business Advantages, an
e-services consulting organization, in exchange for $1.2 million in cash and 1.1
million shares of its common stock; Servicesoft also assumed or issued to former
employees and warrant holders of Internet Business Advantages stock options and
warrants to purchase approximately 72,000 shares of its common stock. The total
cost of the acquisition, including transaction costs, was $12.1 million.
Servicesoft accounted for the acquisition as a purchase business combination.
Accordingly, the results of operations of Internet Business Advantages have been
included with the results of operations for Servicesoft for periods subsequent
to the date of the acquisition and the acquired net assets were recorded at
their estimated fair values at the effective date of the acquisition, resulting
in $11.4 million recorded as goodwill and other intangibles.

     Of the $24.7 million total cost of the Balisoft and Internet Business
Advantages transactions, Servicesoft allocated $19.9 million of the combined
transaction prices to goodwill and other intangible assets to be amortized over
three years commencing on the date of the respective transactions.

RESULTS OF SERVICESOFT OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 2000
COMPARED TO THE SIX MONTHS ENDED JUNE 30, 1999

  Revenue

     Total revenue increased $9.8 million, or 444%, to $12.0 million in the
first six months of 2000 from $2.2 million in the same period of the prior year.
Software license revenue increased $3.6 million, or 275%,

                                       127
<PAGE>   135

to $4.9 million in the first six months of 2000 from $1.3 million in the same
period of the prior year. Services revenue increased $6.2 million, or 688%, to
$7.1 million in the first six months of 2000 from $903,000 in the same period of
the prior year. The increase in software license revenue was primarily due to
increased market demand for and acceptance of Servicesoft's products, the
expansion of Servicesoft's product offerings and an expanding customer base. The
remainder of the increase was largely attributable to revenues generated from
the additional professional service staff added from Servicesoft's December 1999
acquisition of Internet Business Advantages. In August 1999, Servicesoft
released its 2000 suite of products, including integrated self-service, e-mail
management and live interaction applications. This expanded product offering has
been a significant factor in the increased demand for Servicesoft's products.
Servicesoft believes that growth in software license revenue depends on its
ability to provide its clients with the support, training, consulting and
implementation services they require to successfully build, deploy and maintain
e-service applications. Accordingly, Servicesoft expects that services revenue
will increase in the future to the extent that additional clients license its
products and as it expands both its capacity to deliver professional services
and the scope of its professional services offerings.

  Cost of Revenue

     Cost of software license revenue increased $213,000, or 135%, to $371,000
in the first six months of 2000 from $158,000 in the same period of the prior
year. The increase was attributable to an increase in licenses sold during the
first six months of 2000 and an increase in third-party products embedded in or
licensed with the Servicesoft 2000 suite of products. Cost of services revenue
increased $7.1 million, or 695%, to $8.1 million in the first six months of 2000
from $1.0 million in the same period of the prior year. Of this increase, $3.7
million was due to the expansion of the professional services organization
through Servicesoft's acquisition of Internet Business Advantages in December
1999. The remainder of the increase was related to additional headcount that
resulted in increased salary and benefits and recruitment, and facility,
computer and communication expenses. Servicesoft expects the cost of software
license revenue to increase in the future in absolute dollar terms as additional
clients license its products and as Servicesoft licenses technology that it may
choose to embed in or license with its products. Servicesoft further expects the
cost of services revenue to increase in the future to the extent that it
continues to gain new clients. Cost of services revenue can be expected to vary
significantly from period to period, depending on the mix of services
Servicesoft provides, whether such services are provided by Servicesoft or
third-party contractors, and overall utilization rates of Servicesoft's services
professionals.

  Operating Expenses

     Research and Development.  Research and development expenses increased $2.3
million, or 133%, to $3.9 million in the first six months of 2000 from $1.7
million in the same period of the prior year. The increase was due to increases
in personnel costs and facility, computer and communication expenses related to
the increase in headcount from Servicesoft's merger with Balisoft in February
1999 and additional hiring. Servicesoft believes that continued investment in
research and development will be crucial to achieving and maintaining leadership
in the market for e-service software. As a result, Servicesoft expects research
and development costs to increase in future periods.

     Sales and Marketing.  Sales and marketing expenses increased $10.4 million,
or 232%, to $14.9 million in the first six months of 2000 from $4.5 million in
the same period of the prior year. Of this increase, approximately $3.3 million
was due to the expansion of the sales and marketing workforce, approximately
$1.9 million was due to the development of strategic alliances and vertical
marketing organizations, approximately $1.7 million was due to increased
marketing promotions and approximately $1.3 million resulted from increased
commissions. The remainder of the increase was due to the opening of satellite
offices and an increase in computer and communication expenses related to the
increase in headcount. Servicesoft believes that sales and marketing expenses
will increase in future periods as it continues to expand its sales and
marketing efforts. Sales and marketing expenses can be expected to fluctuate as
a percentage of total revenue from period to period resulting from the hiring
and training of new sales personnel and the timing of the marketing activities
of Servicesoft.

                                       128
<PAGE>   136

     General and Administrative.  General and administrative expenses increased
$3.1 million, or 194%, to $4.7 million in the first six months of 2000 from $1.6
million in the same period of the prior year. Of this increase, approximately
$735,000 was due to increased personnel. The remainder of the increase was due
to an increase in accounting fees, legal fees and facility, computer and
communication expenses. Servicesoft believes that general and administrative
costs will increase as it invests in the personnel and systems necessary to
support its expanding operations and as it incurs the expenses associated with
being a public company.

     Amortization of Goodwill and Other Intangible Assets.  Amortization expense
increased $2.3 million, or 215%, to $3.4 million in the first six months of 2000
from $1.1 million in the same period of the prior year. This increase resulted
from Servicesoft's merger with Balisoft in February 1999 and its acquisition of
Internet Business Advantages in December 1999. For the full year ending December
31, 2000, Servicesoft expects to incur amortization expense of approximately
$6.7 million as a result of goodwill and other intangible assets recorded in
connection with these transactions.

     Stock Compensation.  Servicesoft incurred compensation charges of $3.6
million in the first six months of 2000 and $27,000 in the same period of the
prior year related to stock options and restricted stock with exercise or
purchase prices below the deemed fair market value of the common stock for
financial reporting purposes on the date of grant and related to modifications
of certain stock options. Additionally, unvested outstanding options and
restricted stock will continue to vest over the next four years, and related
deferred stock compensation of $19.7 million recorded as of June 30, 2000 will
be amortized to compensation expense over that period. In connection with the
resignation of the President and Chief Executive Officer of Servicesoft in July
2000, Servicesoft is allowing him to continue to vest on certain restricted
common shares, for which Servicesoft recorded a non-cash stock compensation
charge of $4.1 million.

     During the six months ended June 30, 2000, Servicesoft issued options to
purchase 1,575,541 shares of common stock at various exercise prices resulting
in deferred compensation of approximately $5.7 million, which has been recorded
as of the option issuance dates. Such deferred compensation is being amortized
to stock compensation expense over the vesting term of the options, generally
four years.

  Interest and Other Income (Expense), Net

     Interest and other income (expense), net was $453,000 of net income in the
first six months of 2000 and was $1,000 of net expense in the same period of the
prior year. Interest income increased $437,000 to $499,000 in the first six
months of 2000 from $62,000 in the same period of the prior year. The increase
is primarily attributable to investment of the funds raised by Servicesoft
through the issuance of its Series J redeemable convertible preferred stock in
January 2000. Interest expense increased $29,000 to $32,000 in the first six
months of 2000 from $3,000 in the same period of the prior year. Other expense,
net decreased $46,000 to $14,000 in the first six months of 2000 from $60,000 in
the same period of the prior year. The majority of this expense in the first six
months of 1999 was related to the settlement of a patent infringement dispute.

  Cost of Revenue

     Cost of software license revenue increased $258,000, or 174%, to $406,000

embedded in or licensed with the Servicesoft 2000 suite of products. Cost of
services revenue increased $2.3 million, or 207%, to $3.4 million in 1999 from
$1.1 million in 1998. Of this increase, $1.3 million was due to the expansion of
the professional services workforce to meet customer demand and to provide
support to the increased number of clients. The remainder of the increase was
related to an increase in recruitment, facilities, computers and communications
expenses related to the increase in headcount.

  Operating Expenses

     Research and Development.  Research and development expenses increased $3.0
million, or 258%, to $4.2 million in 1999 from $1.2 million in 1998. Of this

Servicesoft merged with Balisoft for total consideration of $12.6 million. In
December 1999, Servicesoft acquired Internet Business Advantages for total
consideration of $12.1 million. In 1999, Servicesoft incurred amortization
expense of $2.7 million.

related to the issuance of stock options and restricted stock with exercise or
purchase prices below the deemed fair market value of the common stock for
financial reporting purposes on the date of the grant and related to
modifications of certain stock options. Servicesoft incurred no stock
compensation charges in 1998.

  Interest and Other Income (Expense), Net

     Interest and other income (expense), net was $214,000 of net income in 1999
and was $620,000 of net expense in 1998. Interest income increased $152,000 to
$320,000 in 1999 from $168,000 in 1998. The increase is directly attributable to
the investment of funds received as part of Servicesoft's merger with Balisoft
and funds raised by Servicesoft through the issuance of its Series I convertible
preferred stock. Interest expense decreased $503,000 to $35,000 in 1999 from
$538,000 in 1998. Of the $538,000 recorded in 1998, $530,000 related to the

</TABLE>

     Servicesoft's total revenue increased in each quarter of 1999 and the first
two quarters of 2000 due to an expanding e-service market and as it increased
its product and services offerings and its sales and marketing activities.
Particularly, Servicesoft has seen a significant increase in customer demand
since it released the Servicesoft 2000 suite of products in the third quarter of
1999.

     Cost of revenue has increased each quarter in conjunction with the
increases in total revenue. Cost of software license revenue was
disproportionately higher in the quarter ended September 30, 1999 primarily due
to higher than normal sales of a third-party product. Cost of services revenue
increased during each quarter of 1999 as Servicesoft increased the number of
professional services consultants and customer care representatives in response
to its growing customer base. The increase in cost of services revenue during
the quarter ended March 31, 2000 was the result of Servicesoft's acquisition of
Internet Business Advantages.

     Operating expenses have generally increased in absolute dollars each
quarter as Servicesoft has increased staffing in sales and marketing, research
and development and general and administrative functions. In addition,
Servicesoft's merger with Balisoft in February 1999 significantly increased its
research and development costs commencing in the second quarter of 1999. With
the release of Servicesoft's 2000 suite of products early in the third quarter
of 1999, Servicesoft increased its marketing activities, which has had a
significant impact on sales and marketing expenses. As part of the purchase
accounting for its merger with Balisoft in February and its acquisition of
Internet Business Advantages in December, Servicesoft recorded goodwill and
other intangible assets of $19.9 million. These intangible assets are being
amortized over a three year period as reflected in amortization of goodwill and
other intangible assets. Also, during 1999 and the first two quarters of 2000,
Servicesoft recorded deferred stock compensation charges totaling $23.1 million
in connection with stock options and restricted stock granted during 1999 and
the first two quarters of 2000. Servicesoft is amortizing this amount over the
vesting

                                       133
<PAGE>   141

periods of the applicable options or restricted stock, and it has recognized
stock compensation expense of $8,000, $19,000, $1.1 million and $793,000 in the
four quarters of 1999, and $2.0 million and $1.6 million for the first two
quarters of 2000. The increased amounts in the third and fourth quarters of 1999
and the first two quarters of 2000 are due to the significant increase in the
deemed fair market value of Servicesoft's stock for financial reporting purposes
during 1999 and 2000 and the increase in the number of stock options and
restricted stock granted.

     Because of the significant changes to Servicesoft's business in 1999,
Servicesoft cannot forecast operating expenses based on historical results.
Accordingly, Servicesoft bases its expenses in part on future revenue
projections. Most of these expenses are fixed in the short term, and Servicesoft
may not be able to quickly reduce spending if revenue is lower than it has
projected. Servicesoft's availability to forecast accurately its quarterly
revenue is limited due to the long sales cycle of its software products, which
makes it difficult to predict the quarter in which license sales will occur, and
the variability of client demand for professional services. Servicesoft would
expect its business, operating results and financial condition to be materially
adversely affected if revenue does not meet projections and that net losses in a
given quarter would be even greater than expected.

     Servicesoft expects its revenue and operating results may vary
significantly from quarter to quarter. A number of factors are likely to cause
these variations, including:

     - demand for Servicesoft's products and services;

     - the timing of sales of Servicesoft's products and services;

     - unexpected delays in introducing new products and services;

     - increased expenses, whether related to sales and marketing, product
       development or administration;

     - changes in the rapidly evolving market for e-service solutions;

     - the mix of product license and services revenue;

     - the mix of services provided and whether services are provided by
       Servicesoft staff or third-party contractors;

     - the mix of domestic and international sales; and

     - costs related to possible acquisitions of technology or business.

     Accordingly, Servicesoft believes that quarter-to-quarter comparisons of
its operating results are not necessarily meaningful. Servicesoft plans to
increase its operating expenses to expand sales and marketing operations,
develop new distribution channels, fund greater levels of research and
development, broaden professional services and support and improve operational
financial systems. If Servicesoft's revenue does not increase along with these
expenses, its business, operating results or financial condition could be
materially adversely affected and net losses in a given quarter would be even
greater than expected. Investors should not rely on the results of one quarter
as an indication of future performance.

  Net Operating Losses and Tax Credit Carryforwards

     As a result of taxable losses generated, Servicesoft has not recorded any
provisions for income taxes for the years ended December 31, 1997, 1998 and
1999. As of December 31, 1999, Servicesoft had net operating loss carryforwards
of $37.6 million, $29.1 million and $5.1 million for federal, state and foreign
income tax purposes. The net operating loss carryforwards will expire at various
dates through 2019, if not used. Under the provisions of the Internal Revenue
Code, substantial changes in Servicesoft's ownership may limit the amount of net
operating loss carryforwards that could be utilized annually in the future to
offset taxable income. Servicesoft has established a full valuation allowance in
its consolidated financial statements reflecting the uncertainty of its ability
to use available net operating loss carryforwards and other deferred tax assets.

  Liquidity and Capital Resources

     Since Servicesoft's inception, it has primarily funded its operations and
met its capital expenditure requirements through the private sale of equity
securities, resulting in net proceeds of $48.5 million through December 31,
1999. In addition, in January 2000, Servicesoft sold additional equity
securities in a private sale resulting in additional net proceeds of $31.2
million. Cash used in operating activities was $1.2 million, $3.6 million, $13.8
million and $18.4 million in 1997, 1998, 1999 and the six months ended June 30,
2000. The $13.8 million of cash used in operating activities for the year ended
December 31, 1999 results from a net loss adjusted for non-cash charges and
includes an increase in client accounts receivables of approximately $4.2
million from December 31, 1998. This increase is directly attributable to
increased client contracts signed at the close of the quarter ended December 31,
1999 containing immediate invoicing terms. The $18.4 million of cash used in
operating activities for the six months ended June 30, 2000 results from a net
loss adjusted for non-cash charges offset by an increase in deferred revenue.
This increase is directly attributable to increased client contracts signed at
the close of the six months ended June 30, 2000 for which no services were
performed prior to June 30, 2000.

     To date, Servicesoft's investing activities have consisted primarily of
capital expenditures totaling $25,000, $337,000 and $2.3 million in 1997, 1998
and 1999. For the six months ended June 30, 2000, Servicesoft's investing
activities have primarily consisted of capital expenditures of $3.9 million and
purchases of marketable securities of $3.9 million. In 1999, Servicesoft's
capital expenditures were offset by cash acquired in its merger with Balisoft
and its acquisition of Internet Business Advantages, which totaled $3.4 million
after cash paid in the Internet Business Advantages acquisition and for
transaction expenses. Capital expenditures consist primarily of property and
equipment, mainly furniture and computer hardware and software, for
Servicesoft's growing employee base. Servicesoft expects that its capital
expenditures will increase as its employee base grows. At June 30, 2000,
Servicesoft did not have any material commitments for capital expenditures.

     At June 30, 2000, Servicesoft had $14.3 million in cash, cash equivalents
and marketable securities and $8.9 million in working capital. Net cash provided
by financing activities in 1997, 1998, 1999 and the six months ended June 30,
2000 was $817,000, $6.0 million, $17.2 million and $30.3 million. On January 13,
2000, Servicesoft completed an offering of 3,481,478 shares of its Series J
redeemable convertible preferred stock for net proceeds to it of $31,241,000. As
the fair market value of Servicesoft's common stock, for financial reporting
purposes, was greater than the issuance price of its Series J preferred stock,
the right of conversion incorporated into the Series J preferred stock
constitutes a beneficial conversion feature which was determined to have a value
of $17,303,000 and has been treated as a deemed preferred stock dividend as of
the date of issue, thus increasing the net loss attributable to common
stockholders.

     Servicesoft believes that its cash, cash equivalents, short-term
investments and commercial credit facilities will be sufficient to meet its
working capital needs through the end of the fiscal year. Thereafter,
Servicesoft may require additional funds to support its working capital
requirements or for other purposes and may seek to raise additional funds. Such
additional financing may not be available at all, or if available, such
financing may not be obtained on terms favorable to Servicesoft and may be
dilutive.

  Recent Accounting Pronouncements

     In December 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued Statement of Position
No. 98-9, "Modification of SOP No. 97-2, Software Revenue Recognition, with
Respect to Certain Transactions" ("SOP 98-9"). SOP 98-9 amends SOP 97-2 to
require recognition of revenue using the "residual method" in circumstances
outlined in SOP 98-9. Under the residual method, revenue is recognized as
follows: (1) the total fair value of undelivered elements, as indicated by
vendor specific objective evidence, is deferred and subsequently recognized in
accordance with the relevant sections of SOP 97-2 and (2) the difference between
the total arrangement fee and the amount deferred for the undelivered elements
is recognized as revenue related to the delivered elements. SOP 98-9 is
effective for transactions entered into during fiscal years beginning

                                       135
<PAGE>   143

after March 15, 1999 (fiscal year 2000 for Servicesoft), however early adoption
is permitted. Servicesoft has adopted SOP 98-9.

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability measured at its fair value.
SFAS No. 133, as recently amended, is effective for fiscal years beginning after
June 15, 2000. Because Servicesoft does not currently hold any derivative
instruments and does not currently engage in hedging activities, it expects the
adoption of SFAS No. 133 will not have a material impact on its financial
position or operating results.

     In March 2000, the Financial Accounting Standard Board issued FASB
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation -- an interpretation of APB Opinion No. 25" ("FIN 44"). FIN 44
clarifies the application of APB Opinion No. 25 and among other issues clarifies
the following: the definition of an employee for purposes of applying APB
Opinion No. 25; the criteria for determining whether a plan qualifies as a
noncompensatory plan; the accounting consequence of various modifications to the
terms of previously fixed stock options or awards; and the accounting for an
exchange of stock compensation awards in a business combination. FIN 44 became
effective on July 1, 2000, but certain conclusions in FIN 44 cover specific
events that occurred after either December 15, 1998 or January 12, 2000.
Servicesoft does not expect the application of FIN 44 to have a material impact
on its financial position or results of operations.

  Quantitative and Qualitative Disclosures about Market Risk

     Servicesoft develops its products in Canada and the United States.
Servicesoft sells its products globally, primarily through its direct sales
force. As a result, Servicesoft's financial results are affected by factors such
as changes in foreign currency exchange rates and weak economic conditions in
foreign markets. In the future, Servicesoft expects to increase its
international operations in its existing markets and in geographic locations
where it does not have any current operations.

     Servicesoft collects a portion of its revenue and pays a portion of its
operating expenses in foreign currencies. As a result, changes in currency
exchange rates from time to time may affect Servicesoft's operating results.
Currently, Servicesoft does not engage in hedging transactions to reduce its
exposure to changes in currency exchange rates, although it may do so in the
future. Servicesoft cannot assure you, however, that any efforts it may make in
the future to hedge its exposure to currency exchange rate change will be
successful.

     Servicesoft's object-oriented knowledge-base technology allows diverse
domains of knowledge to be easily and accurately represented and links related
pieces of information together and promotes re-use of knowledge in multiple
contexts. The foundation of the knowledge base representation lies in using
terms and associations familiar to the authors within an organization. Multiple
knowledge access strategies and algorithms, such as search, case-based
reasoning, decision trees, and expert models, are combined into a single
knowledge engine. Servicesoft's knowledge base technology allows e-service
application developers, using a simple browser function, to set up a knowledge
framework that is specific to their domain and to build and deploy applications
that can manage multiple types of data including content, relations data and
flat files through a single knowledge engine and a single application
programming interface model. This simplifies knowledge authoring and
significantly reduces time to deployment by uncoupling decisions about storage
and data formats from authoring.

  Research and Development

     Servicesoft's future success will depend in part on its ability to
anticipate changes, enhance its current products, develop and introduce new
products that keep pace with technological advancements and address the
increasingly sophisticated needs of its clients. In order to keep pace with this
rapidly changing environment, Servicesoft devotes significant resources toward
research and development. Servicesoft's research and development expenditures
for fiscal 1997, 1998 and 1999 and the six months ended June 30, 2000 were
approximately $930,000, $1.2 million, $4.2 million and $3.9 million,
respectively. Servicesoft expects that it will continue to commit significant
resources to research and development in the future. All research and
development expenses have been expensed as incurred.

  Competition

     The market for the Servicesoft products and services is intensely
competitive, evolving and subject to rapid technological change. Servicesoft
expects the intensity of competition to increase as current competitors expand
their product offerings and new competitors enter the market. Servicesoft
currently faces competition for its products primarily from systems designed by
other e-service software vendors such as Brightware, eGain, Inference, Kana,
Primus, Quintus and ServiceWare, and expects that these vendors will continue to
be a principal source of competition for the foreseeable future. In addition,
from time to time, Servicesoft also competes with companies providing customer
relationship management and call center communications software such as Clarify,
E.piphany, Lucent, Nortel, Siebel and Vantive.

     Servicesoft believes that the principal competitive factors affecting its
market include referenceable customers, the breadth and depth of a given
solution including the integration of a knowledge base, product quality and
performance, customer service, core technology, product scalability and
reliability, product features, the ability to implement solutions quickly and
the value of a given solution. Although Servicesoft believes that its solution
currently competes favorably with respect to these factors, its market is
relatively new and is evolving rapidly. Servicesoft may not be able to maintain
its competitive position against current and potential competitors, especially
those with significantly greater financial, marketing, service, support,
technical and other resources.

     Many of Servicesoft's competitors have longer operating histories,
significantly greater financial, technical, marketing and other resources,
significantly greater name recognition and a larger installed base of customers
than Servicesoft does. In addition, many of Servicesoft's competitors have
well-established relationships with Servicesoft's current and potential clients
and have extensive knowledge of the e-service industry. It is possible that new
competitors or alliances among competitors may emerge and rapidly acquire
significant market share. Servicesoft also expects that competition will
increase as a result of industry consolidations.

OPTION GRANTS IN LAST FISCAL YEAR

     The following table sets forth information with respect to stock options
granted by Servicesoft during the fiscal year ended December 31, 1999 to Mr.
Zarrabian. These options will be assumed by Broadbase in connection with the
merger at the exchange ratio of 1.4404.

     In addition, in July 2000, Servicesoft granted an option to purchase
430,000 shares of Servicesoft common stock at a per-share purchase price of
$14.00. This option will be assumed by Broadbase in connection with the merger
on the terms described in the section of this document entitled "Related Party
Transactions -- Broadbase Transactions" on page 123.

     In November 1999, Servicesoft issued 25,000 shares of restricted
Servicesoft common stock to Mr. Davoli pursuant to its 1999 Stock Option and
Grant Plan. Under the restricted stock agreement, one-third of these shares vest
in April 2000, and the remaining shares vest quarterly thereafter over two years
as long as a service relationship exists between Servicesoft and Mr. Davoli.
Under the 1999 Stock Option and Grant Plan, one-half of Mr. Davoli's unvested
shares will vest in full upon the closing of the merger. Mr. Davoli's remaining
unvested shares will be assumed by Broadbase in connection with the merger.

     The amounts described in the following table under the heading "Potential
Realizable Value at Assumed Rates of Stock Price Appreciation for Option Term"
represents hypothetical gains for Servicesoft common stock that could be
achieved for the options if exercised at the end of the option term. These gains
are based on assumed rates of stock appreciation of 0%, 5% and 10% compounded
annually from the date the options were granted at their expiration date. Actual
gains, if any, on stock option exercises will depend on the future performance
of the common stock and the date on which the options are exercised.

                                APPRAISAL RIGHTS

     Under the Delaware General Corporation Law, Servicesoft stockholders may
object to the merger and demand in writing that Servicesoft pay the fair value
of their shares. Determination of fair value is based on all relevant factors,
but excludes any appreciation or depreciation in anticipation of the applicable
merger. Stockholders who elect to exercise appraisal rights must comply with all
of the procedures to preserve those rights. A copy of Section 262 of the
Delaware General Corporation Law, which sets forth the appraisal rights, is
attached as Annex H to this document.

     Section 262 sets forth the required procedure a stockholder requesting
appraisal must follow. These procedures are complicated and must be followed
completely. Failure to comply with the procedure may cause a termination of your
appraisal rights. The following information is only a summary of the required
procedures, is qualified in its entirety by the provisions of Section 262.
Please review Section 262 for the complete procedures. Neither Broadbase nor
Servicesoft will give you any notice other than as described in this document
and as required by the Delaware General Corporation Law.

     General Requirements.  Section 262 requires generally requires the
following:

     - Written Demand for Appraisal.  You must deliver a written demand for
       appraisal to Servicesoft before the vote is taken at the Servicesoft
       stockholders' meeting. This written demand for appraisal must be separate
       from the action by written consent. In other words, failure to return the
       proxy or returning the proxy with a notation on it will not alone
       constitute demand for appraisal. You should read the paragraphs below for
       more details on making a demand for appraisal;

     - Refrain from Voting for the Merger Proposal.  You must not vote in favor
       of the merger agreement or the merger. If you return a properly executed
       proxy or otherwise vote in favor of the merger agreement or the merger,
       your right to appraisal will terminate, even if you previously filed a
       written demand for appraisal; and

     - Continuous Ownership of Servicesoft Shares.  You must continuously hold
       your shares of Servicesoft stock from the date you make the demand for
       appraisal through the closing of the merger.

     Requirements for Written Demand for Appraisal

     A written demand for appraisal of Servicesoft stock is only effective if it
is signed by, or for, the stockholder of record who owns such shares at the time
the demand is made. The demand must be signed as the stockholder's name appears
on its stock certificate(s). If you are the beneficial owner of Servicesoft
stock but not the stockholder of record, you must have the stockholder of record
sign a demand for appraisal.

     If you own Servicesoft stock in a fiduciary capacity, such as a trustee,
guardian or custodian, you must disclose the fact that you are signing the
demand for appraisal in that capacity.

     If you own Servicesoft stock with more than one person, such as in a joint
tenancy or tenancy in common, all of the owners must sign, or have signed for
them, the demand for appraisal. An authorized agent, which could include one or
more of the joint owners, may sign the demand for appraisal for a stockholder of
record; however, the agent must expressly disclose who the stockholder of record
is and that he or she is signing the demand as that stockholder's agent.

     If you are a record owner, such as a broker, who holds Servicesoft stock as
a nominee for others, you may exercise a right of appraisal with respect to the
shares held for one or more beneficial owners, while not exercising such right
for other beneficial owners. In such a case, you should specify in the written
demand the number of shares as to which you wish to demand appraisal. If you do
not expressly specify the number of shares, we will assume that your written
demand covers all the shares of Servicesoft stock that are in your name.

                                       145
<PAGE>   153

     If you are a Servicesoft stockholder, you should address the written demand
to Servicesoft, Inc., Two Apple Hill Drive, Natick, Massachusetts 01760,
Attention: Daniel J. Kossmann. It is important that Servicesoft receive all
written demands before the vote concerning the merger is taken. As explained
above, this written demand should be signed by, or on behalf of, the stockholder
of record. The written demand for appraisal should specify the stockholder's
name and mailing address, the number of shares of stock owned, and that the
stockholder is thereby demanding appraisal of such stockholder's shares.

     Written Notice.  Within 10 days after the closing of the merger,
Servicesoft must give written notice that the merger has become effective to
each stockholder who has fully complied with the conditions of Section 262.

     Petition with the Chancery Court.  Within 120 days after the closing of the
merger, either Servicesoft or any stockholder who has complied with the
conditions of Section 262, may file a petition in the Delaware Court of
Chancery. This petition should request that the chancery court determine the
value of the shares of Servicesoft stock held by all of the stockholders who are
entitled to appraisal rights. If you intend to exercise your rights of
appraisal, you should file such a petition in the chancery court. Servicesoft
has no intentions at this time to file such a petition. Because Servicesoft has
no obligation to file such a petition, if you do not file such a petition within
120 days after the closing, you will lose your rights of appraisal.

     Withdrawal of Demand.  If you change your mind and decide you no longer
want appraisal rights, you may withdraw your demand for appraisal rights at any
time within 60 days after the closing of the merger. You may also withdraw your
demand for appraisal rights after 60 days after the closing of the merger, but
only with the written consent of Servicesoft. If you withdraw your demand for
appraisal rights, you will receive the merger consideration provided in the
merger agreement.

     Request for Appraisal Rights Statement.  If you have complied with the
conditions of Section 262, you are entitled to receive a statement from
Servicesoft setting forth the number of shares that have demanded appraisal
rights and the number of stockholders who own those shares. In order to receive
this statement, you must send a written request to Servicesoft within 120 days
after the closing of the merger. After the merger, Servicesoft has 10 days after
receiving a request to mail the statement to the stockholder.

     Chancery Court Procedures.  If you properly file a petition for appraisal
in the chancery court and deliver a copy to Servicesoft, Servicesoft will then
have 20 days to provide the chancery court with a list of the names and
addresses of all stockholders who have demanded appraisal rights and have not
reached an agreement with Servicesoft as to the value of their shares. The
chancery court will then send notice to all of the stockholders who have
demanded appraisal rights. If the chancery court decides it is appropriate, it
has the power to conduct a hearing to determine whether the stockholders have
fully complied with Section 262 of the Delaware General Corporation Law and
whether they are entitled to appraisal rights under that section. The chancery
court may also require you to submit your stock certificates to the Registry in
Chancery so that it can note on the certificates that an appraisal proceeding is
pending. If you do not follow the chancery court's directions, you may be
dismissed from the proceeding.

     Appraisal of Chancery Shares.  After the chancery court determines which
stockholders are entitled to appraisal rights, the chancery court will appraise
the shares of stock. To determine the fair value of the shares, the chancery
court will consider all relevant factors except for any appreciation or
depreciation due to the anticipation or accomplishment of the merger. After the
chancery court determines the fair value of the shares, it will direct
Servicesoft to pay that value to the stockholders who are entitled to appraisal
rights. The chancery court can also direct Servicesoft to pay interest, simple
or compound, on that value if the chancery court determines that interest is
appropriate. In order to receive the fair value for your shares, you must
surrender your stock certificates to Servicesoft.

     The chancery court could determine that the fair value of shares of
Servicesoft stock is more than, the same as, or less than the merger
consideration. In order words, if you demand appraisal rights, you could receive
less consideration than you would under the merger agreement.

                                       146
<PAGE>   154

     Costs and Expenses of Appraisal Proceeding.  The costs and expenses of the
appraisal proceeding may be assessed against Servicesoft and the stockholders
participating in the appraisal proceeding, as the chancery court deems equitable
under the circumstances. You can request that the chancery court determine the
amount of interest, if any, Servicesoft should pay on the value of stock owned
by stockholders entitled to the payment of interest. You may also request that
the chancery court allocate the expense of the appraisal action incurred by any
stockholder pro rata against the value of all of the shares entitled to
appraisal.

     Loss of Stockholder's Rights.  If you demand appraisal rights, after the
closing of the merger you will not be entitled to:

     - vote your shares of stock, for any purpose, for which you have demanded
       appraisal rights;

     - receive payment of dividends or any other distribution with respect to
       such shares, except for dividends or distributions, if any, that are
       payable to holders of record as of a record date prior to the effective
       time of the merger; or

     - receive the payment of the consideration provided for in the merger
       agreement.

     However, you can regain these rights if no petition for an appraisal is
filed within 120 days after the closing of the merger, or if you deliver to
Servicesoft a written withdrawal of your demands for an appraisal and your
acceptance of the merger, either within 60 days after the closing of the merger
or with the written consent of Servicesoft. As explained above, these actions
will also terminate your appraisal rights. However, an appraisal proceeding in
the chancery court cannot be dismissed without the chancery court's approval.
The chancery court may condition its approval upon any terms that it deems just.

     IF YOU FAIL TO COMPLY STRICTLY WITH THESE PROCEDURES YOU WILL LOSE YOUR
APPRAISAL RIGHTS. CONSEQUENTLY, IF YOU WISH TO EXERCISE YOUR APPRAISAL RIGHTS,
WE STRONGLY URGE YOU TO CONSULT A LEGAL ADVISOR BEFORE ATTEMPTING TO EXERCISE
YOUR APPRAISAL RIGHTS.

             CAUTIONARY NOTE CONCERNING FORWARD-LOOKING STATEMENTS

     This document and the documents incorporated in this document by reference
contain forward-looking statements within the "safe harbor" provisions of the
Private Securities Litigation Reform Act of 1995 with respect to our financial
condition, results of operations and business, and on the expected impact of the
merger on Broadbase's financial performance. Words such as "anticipates,"
"expects," "intends," "plans," "believes," "seeks," "estimates" and similar
expressions identify forward-looking statements. These forward-looking
statements are not guarantees of future performance and are subject to certain
risks and uncertainties that could cause actual results to differ materially
from the results contemplated by the forward-looking statements. These risks and
uncertainties include:

     - the possibility that the value of the Broadbase common stock to be issued
       to Servicesoft stockholders in the merger will decrease before the merger
       closes, in which event the number of shares of Broadbase common stock to
       be received by Servicesoft stockholders would not be adjusted;

     - the possibility that the anticipated benefits from the merger, including
       the potential strategic synergies and the possibility of increased
       overall sales, will not be fully realized;

     - the possibility that the integration of Broadbase's and Servicesoft's
       software products may not be completed in a timely manner, or at all, or
       may cost more than anticipated;

     - the uncertainty of Servicesoft customers' acceptance of Broadbase's
       software products, Broadbase customers' acceptance of Servicesoft's
       software products, and overall market acceptance of the integrated
       Broadbase/Servicesoft software solution;

     - the operational and personnel-related challenges in integrating Broadbase
       and Servicesoft;

     - the possible loss of key employees as a result of the merger;

     - other risks and uncertainties, including the risk of disruption of sales
       momentum as a result of the merger, the risk that the merger could
       adversely affect Broadbase's or Servicesoft's relationships with
       strategic partners, the risk that the investment community may not
       embrace the proposed merger, which could lead to a decline in Broadbase's
       stock price, and the possibility that the merger may not be completed;
       and

     - other risk factors as may be detailed from time to time in Broadbase's
       public announcements and filings with the SEC.

     In evaluating the merger, you should carefully consider the discussion of
these and other factors in the section entitled "Risk Factors" beginning on page
19.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of Servicesoft, Inc.

     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of redeemable convertible preferred stock
and stockholders' deficit and of cash flows present fairly, in all material
respects, the financial position of Servicesoft, Inc. (formerly Servicesoft
Technologies, Inc.) and its subsidiaries at December 31, 1999 and 1998, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1999 in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF THE BUSINESS AND BASIS OF PRESENTATION:

     Servicesoft, Inc. ("Servicesoft") was originally incorporated as Rosh
Intelligent Systems in 1987, was renamed ServiceSoft Corporation in 1993, was
renamed Servicesoft Technologies, Inc. in 1999 and was subsequently renamed
Servicesoft, Inc. in 2000. Servicesoft develops, markets and delivers software
products and professional services that help businesses provide Internet-based
services to their customers, employees and business partners. To date,
Servicesoft's revenue has been reported and managed through one operating
segment and has resulted from the sale of its products and services to major
corporations in the United States and Europe.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Principles of Consolidation

     The consolidated financial statements include the accounts of Servicesoft
and its wholly owned subsidiaries. Intercompany transactions and balances have
been eliminated.

  Translation of Foreign Currencies

     The functional currency of Servicesoft's foreign subsidiaries is the local
currency, except for a subsidiary in Israel, whose functional currency is the
U.S. dollar. Assets and liabilities of Servicesoft's foreign operations whose
functional currencies are other than the U.S. dollar are translated into U.S.
dollars at the exchange rate in effect at the balance sheet date; revenues and
expenses are translated using the average exchange rates in effect during the
period. The resultant cumulative translation adjustments are included in
accumulated other comprehensive income or loss, which is a separate component of
stockholders' deficit. Foreign currency transaction gains and losses are
included in the determination of net income or loss for the period.

  Unaudited Interim Financial Statements

     The interim consolidated financial statements as of June 30, 2000 and for
the six months ended June 30, 1999 and 2000 are unaudited. Management believes
these unaudited financial statements have been prepared on the same basis as the
audited consolidated financial statements and include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the financial position and results of operations for such
periods. Results for the six months ended June 30, 2000 are not necessarily
indicative of results to be expected for the full fiscal year.

  Revenue Recognition

     Servicesoft recognizes revenue in accordance with Statement of Position
97-2, "Software Revenue Recognition ("SOP 97-2"), as amended by Statement of
Position 98-9. Revenue from software license sales and related implementation
services are recognized using the percentage-of-completion method over the
implementation period, assuming the contract price is fixed and determinable,
binding evidence of the arrangement has been received and collection is
probable. Percentage-of-completion is measured by the percentage of
implementation hours incurred to date compared to the estimated total required
implementation hours. The total amount of revenue to be earned under these
contracts is generally fixed by contractual terms. Servicesoft regularly reviews
its progress on these contracts and revises the estimated time for completing
its implementations. Anticipated losses, if any, on contracts in progress are
recognized when identified. When Servicesoft is not engaged to complete the
software implementation, Servicesoft recognizes revenue upon delivery of the
software to the end user, provided all other revenue recognition criteria are
met. Revenue from software support and maintenance agreements, which are priced
based on a fixed percentage of the related products' current list prices, is
deferred and recognized ratably over the

                                       F-9

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

term of the agreements generally twelve months. Frequently, Servicesoft's sales
include software licenses, related implementation services and a maintenance and
support arrangement. The total contract value is attributed first to the
maintenance and support arrangement based on its fair value, equal to its stated
price as a fixed percentage of the related product's current list price; the
remainder of the total contract value is then attributed to the software license
and related implementation services, with the effect that discounts inherent in
the total contract value are attributed to the software license and related
implementation services. The Company does not offer its customers any rights of
return.

  Cash and Cash Equivalents

     Servicesoft considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. Cash
equivalents consist of overnight certificates of deposit. Restricted cash
represents required collateral on certain capital leases. The restricted cash is
released to Servicesoft after one year.

  Financial and Credit Risk

     Financial instruments which expose Servicesoft to concentrations of credit
risk consist primarily of cash equivalents and accounts receivable. Servicesoft
invests primarily in money market accounts with large commercial banks with
strong credit ratings. Servicesoft provides credit to customers in the normal
course of business. Collateral is not required for accounts receivable, but
evaluation of customers' credit and financial condition is performed
periodically. Servicesoft maintains reserves for potential credit losses and
such losses have been within management's expectations.

  Fair Value of Financial Instruments

     Financial instruments, including cash, cash equivalents, accounts
receivable, accounts payable and redeemable convertible preferred stock, are
carried in the consolidated financial statements at amounts that approximated
fair value as of December 31, 1997, 1998 and 1999. Fair values are based on
quoted market prices and assumptions concerning the amount and timing of
estimated future cash flows and assumed discount rates, reflecting varying
degrees of perceived risk.

  Property and Equipment

     Property and equipment are stated at cost. Depreciation is provided using
the straight-line method, over the estimated useful lives of the assets,
typically three to five years.

  Goodwill and Other Intangible Assets

     Intangible assets result from Servicesoft's mergers or acquisitions of
businesses (Note 3) accounted for under the purchase method and consist of
identifiable assets, including completed technology, non-compete agreements and
workforce, as well as goodwill. Intangible assets are recorded at cost, net of
accumulated amortization. Identifiable intangible assets and goodwill are
amortized on a straight-line basis over their estimated useful lives of three
years. Servicesoft periodically evaluates its goodwill for potential impairment.
Recoverability of goodwill not identified with other impaired assets is assessed
based on the expected cash flows of Servicesoft, considering a number of factors
including past operating results, budgets and economic projections, market
trends and product development cycles.

  Impairment of Long-Lived Assets

     In accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to be
Disposed of," Servicesoft periodically

evaluates its long-lived assets, including intangible assets, for potential
impairment. Recoverability of these assets is assessed based on undiscounted
expected cash flows from the assets, considering a number of factors including
past operating results, budgets and economic projections, market trends and
product development cycles. An impairment in the carrying value of each asset is
assessed when the undiscounted expected cash flows derived from the asset are
less than its carrying value. Through December 31, 1999, Servicesoft has not
recognized an impairment loss on its long-lived assets.

  Research and Development and Software Development Costs

     Research and development expenditures, except for certain software
development expenditures, are expensed as incurred. Software development costs
incurred after technological feasibility has been achieved and until the
products are available for sale are capitalized and amortized over the life of
the product. Costs of internally developed software which qualify for
capitalization have not been material to date.

  Stock Compensation

     Stock options and restricted stock issued to employees and members of
Servicesoft's Board of Directors are accounted for in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and
related interpretations ("APB 25"); accordingly, compensation expense is
recorded for options and restricted stock awarded to employees and directors to
the extent that the exercise/purchase prices are less than the common stock's
fair market value, for financial reporting purposes, on the date of grant, where
the number of shares and exercise/purchase price are fixed. The difference
between the fair value of Servicesoft's common stock and the exercise/purchase
price of the stock option or restricted stock awards is recorded as deferred
stock compensation. Deferred stock compensation is amortized to compensation
expense over the vesting period of the underlying stock option or restricted
stock. Servicesoft follows the disclosure requirements of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS
123") (Note 7). All stock-based awards to non-employees are accounted for at
their fair value in accordance with SFAS 123.

  Advertising Costs

     Advertising costs are included in sales and marketing expenses and are
expensed as incurred. Advertising costs were $2,000, $140,000 and $298,000 for
the years ended December 31, 1997, 1998 and 1999, respectively.

  Income Taxes

     Deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect in the years in which the differences are expected
to reverse. A valuation allowance against deferred tax assets is recorded if,
based upon the weight of available evidence, it is more likely than not that
some or all of the deferred tax assets will not be realized. Servicesoft does
not provide for U.S. income taxes on the undistributed earnings of its foreign
subsidiaries, which Servicesoft considers to be permanent investments.

  Net Loss Per Common Share

     Servicesoft computes net loss per common share in accordance with Statement
of Financial Accounting Standards No. 128, "Earnings per Share," ("SFAS 128").
Under the provisions of SFAS 128, basic net loss per common share is computed by
dividing net loss attributable to common stockholders by the weighted average
number of common shares outstanding. There is no difference between basic and
diluted net loss per share since potential common shares from the conversion of
redeemable convertible preferred stock and the exercises of options and warrants
are anti-dilutive for all periods presented. The

calculations of diluted net loss per common share for the years ended December
31, 1997, 1998, 1999 and the six months ended June 30, 1999 and 2000 do not
include 3,437,000, 10,955,000, 14,700,000, 13,620,000 (unaudited) and 19,029,000
(unaudited) potential shares of common stock equivalents, including common stock
options, common and preferred stock warrants, and redeemable convertible
preferred stock, respectively.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

  Recent Accounting Pronouncements

     In December 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued Statement of Position
No. 98-9, "Modification of SOP No. 97-2, Software Revenue Recognition, with
Respect to Certain Transactions" ("SOP 98-9"). SOP 98-9 amends SOP 97-2 to
require recognition of revenue using the "residual method" in circumstances
outlined in SOP 98-9. Under the residual method, revenue is recognized as
follows: (1) the total fair value of undelivered elements, as indicated by
vendor specific objective evidence, is deferred and subsequently recognized in
accordance with the relevant sections of SOP 97-2 and (2) the difference between
the total arrangement fee and the amount deferred for the undelivered elements
is recognized as revenue related to the delivered elements. SOP 98-9 is
effective for transactions entered into during fiscal years beginning after
March 15, 1999 (fiscal year 2000 for Servicesoft), however early adoption is
permitted. Servicesoft has adopted SOP 98-9.

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability measured at its fair value.
SFAS 133, as recently amended by SFAS 137, "Accounting for Derivative
Instruments and Hedging Activities -- Deferral of the Effective Date of FASB
Statement No. 133," is effective for fiscal years beginning after June 15, 2000.
Because Servicesoft does not currently hold any derivative instruments and does
not currently engage in hedging activities, Servicesoft does not expect the
adoption of SFAS 133 will not have a material impact on its financial position
or operating results.

     In March 2000, the Financial Accounting Standard Board issued FASB
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation -- an interpretation of APB Opinion No. 25" ("FIN 44"). FIN 44
clarifies the application of APB Opinion No. 25 and among other issues clarifies
the following: the definition of an employee for purposes of applying APB
Opinion No. 25; the criteria for determining whether a plan qualifies as a
noncompensatory plan; the accounting consequence of various modifications to the
terms of previously fixed stock options or awards; and the accounting for an
exchange of stock compensation awards in a business combination. FIN 44 will
become effective July 1, 2000, but certain conclusions in FIN 44 cover specific
events that occurred after either December 15, 1998 or January 12, 2000.
Servicesoft does not expect the application of FIN 44 to have a material impact
on its financial position or results of operations.

3. ACQUISITIONS

  Balisoft Technologies Inc.

     On February 12, 1999, Servicesoft completed its merger with Balisoft
Technologies Inc. ("Balisoft"), a company that develops e-mail management and
real-time internet collaboration applications. In connection with the
acquisition, Servicesoft issued 2,205,915 shares of exchangeable common stock
(Note 6) valued at $3,760,000, issued 2,281,653 shares of exchangeable preferred
stock (exchangeable into Series H redeemable convertible preferred stock) (Note
5) valued at $7,773,000, and assumed or issued options and warrants to purchase
641,275 shares of Servicesoft common stock valued at $780,000. Servicesoft
valued the options and warrants included in the purchase consideration based on
a Black Scholes computation of their fair value at the date of grant;
assumptions used included a risk-free interest rate of 5.25%, no dividend yield,
volatility of 100%, weighted average expected life of 5 years, and fair value of
the underlying common stock of $1.70 per share. The total consideration of
$12,313,000 represented by the Servicesoft stock and options was determined
based on an independent appraisal. In connection with this merger, Servicesoft
incurred costs of $273,000, which are included in the total purchase price for
accounting purposes.

     The merger was accounted for under the purchase method of accounting.
Accordingly, the fair market values of the acquired assets and assumed
liabilities have been included in the consolidated financial statements of
Servicesoft as of the merger date and the results of operations of Balisoft have
been included thereafter. The purchase price was allocated to the acquired
assets and assumed liabilities as follows (in thousands):

  Internet Business Advantages, Inc.

     On December 17, 1999, Servicesoft completed its acquisition of Internet
Business Advantages, Inc. ("IBA"), a company that provides consulting services
primarily focused on using Internet and Intranet technologies. In connection
with the acquisition, Servicesoft paid $1,156,000, issued 1,124,010 shares of
common stock valued at $10,150,000, and assumed or issued options and warrants
to purchase 71,745 shares of Servicesoft common stock valued at $475,000.
Servicesoft valued the options included in the purchase consideration based on a
Black Scholes computation of their fair value at the date of grant; assumptions
used included a risk-free interest rate of 5.25%, no dividend yield, volatility
of 100%, weighted average expected life of 5 years, and fair value of the
underlying common stock of $9.03 per share. The total consideration of
$11,781,000 represented by the Servicesoft stock and options was determined in
connection with an independent appraisal. In connection with this acquisition,
Servicesoft incurred costs of $295,000, which are included in the total purchase
price for accounting purposes.

     The acquisition was accounted for under the purchase method of accounting.

</TABLE>

     On February 12, 1999, all outstanding shares of Series F and Series G
preferred stock were converted into 5,323,420 shares of Series H preferred
stock. On the date of the conversion, Servicesoft reclassified the book value of
the Series F and Series G preferred stock of $25,602,000 to Series H preferred
stock. As part of the Balisoft merger, Servicesoft issued 2,281,653 shares of
exchangeable preferred stock. The exchangeable preferred stock has rights
identical to the outstanding Series H preferred stock and is exchangeable into
shares of Series H preferred stock at any time at the option of the holder;
accordingly, the exchangeable preferred stock has been included within the
balance of outstanding Series H preferred stock. During 1999, Servicesoft
recorded $1,680,000 of accretion to reflect cumulative amounts payable to the
Series H preferred stockholders upon redemption.

     On June 18, 1999, Servicesoft issued 3,982,271 shares of Series I preferred
stock for proceeds to Servicesoft of $16,327,000, prior to any fees or offering
costs. During 1999, Servicesoft recorded $884,000 of accretion to reflect
cumulative amounts payable to the Series I preferred stockholders upon
redemption.

     The Series H preferred stock and the Series I preferred stock
(collectively, the "preferred stock") have the following characteristics:

  Conversion

     Each share of preferred stock is convertible at any time, at the option of
the holder based on specified formula (one-for-one as of December 31, 1999),
subject to anti-dilution adjustments, as defined. All shares of preferred stock
will automatically convert into common stock upon the vote of the holders of
two-thirds of the outstanding shares of preferred stock or upon an initial
public offering of common stock with gross proceeds to Servicesoft of at least
$30,000,000 and an offering which places the value of Servicesoft at not less
than $150,000,000.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  Voting and Dividends

     Holders of the preferred stock are entitled to votes equaling the number of
shares of common stock into which their shares may be converted. The holders of
preferred stock are entitled to annual, noncumulative dividends of 6% of the
original issue price, as defined, when and if declared by Servicesoft's Board of
Directors.

  Liquidation

     In the event of liquidation, dissolution or winding up of Servicesoft, the
holders of Series I preferred stock are entitled to a liquidation preference of
$4.10 per share plus all declared and unpaid dividends thereon, prior to any
distribution to holders of Series H preferred stock or common stock. Upon the
satisfaction of the Series I preferred stock liquidation preference, the holders
of Series H preferred stock are entitled to an aggregate liquidation preference
of $19,203,186, prior to any distribution to holders of common stock. Any
remaining assets after the liquidation preference payments made to the preferred
stock will be shared ratably by the common stockholders until the holders
receive the per share liquidation amount that the Series H preferred
stockholders received. After that point, the remaining assets will be shared
ratably by the Series H stockholders, on an as-converted basis, and the common
stockholders until the Series H stockholders and the common stockholders receive
the per share liquidation amount that the Series I preferred stockholders
received. Any remaining assets will be shared ratably among the Series I and
Series H stockholders, on an as-converted basis, and the common stockholders.

  Redemption

     On each of February 10, 2004, 2005 and 2006, Servicesoft, upon the written
election of at least a majority of the holders of preferred stock, at the option
of any holder, is obligated to redeem one-third of the shares of the preferred
stock outstanding on February 10, 2004. The redemption price for each share of
Series H and Series I preferred stock will be $2.53 and $4.10 per share,
respectively, plus 10% per year compounded on each anniversary date of the
issuance of each series of preferred stock, plus declared and unpaid dividends
on each series of preferred stock.

  Series J Preferred Stock Offering

     On January 13, 2000, Servicesoft completed an offering of 3,481,478 shares
of its Series J redeemable convertible preferred stock (the "Series J preferred
stock") for proceeds to Servicesoft of $31,438,000, prior to any fees or
offering costs. The Series J preferred stock has substantially identical voting,
dividend, redemption and conversion rights as the Series H and Series I
preferred stock, except the redemption amount per share. In the event of any
liquidation, dissolution or winding-up of Servicesoft, the holders of Series J
preferred stock have a liquidation preference above Series H and Series I
preferred stock and are entitled to receive $9.03 per share prior to any
distributions to holders of Series H and Series I preferred stock and common
stock. As the fair market value of Servicesoft's common stock, for financial
reporting purposes, was greater than the issuance price of the Series J
preferred stock, the right of conversion incorporated into the Series J
preferred stock constitutes a beneficial conversion feature which was determined
to have a value of $17,303,000 and has been treated as a deemed preferred stock
dividend as of the date of issue, thus increasing the net loss attributable to
common stockholders.

  Preferred Stock Warrant

     In January 1998, Servicesoft issued a warrant to purchase 117,188 shares of
Series G preferred stock. This warrant, which was issued in connection with a
software development and license agreement, was immediately exercisable at a
price of $2.56 per share and expires in 2003. In connection with the conversion
of the Series G preferred stock to Series H preferred stock, this warrant was
amended to

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

provide for the purchase of 63,025 shares of Series H preferred stock at an
exercise price of $4.76 per share. This warrant was determined to have an
immaterial value on the date of issue.

     As of December 31, 1999, Servicesoft had 11,650,369 shares of common stock
reserved for issuance upon the conversion and exchange of preferred stock and
the exercise of the outstanding preferred stock warrant.

6. STOCKHOLDERS' DEFICIT

  Stock Split

     On February 12, 1999, the Board of Directors approved a 1-for-0.53781
reverse stock split. All share data have been restated in these consolidated
financial statement to reflect this stock split.

  Exchangeable Common Stock

     As part of the Balisoft acquisition, Servicesoft issued 2,205,915 shares of
exchangeable common stock. The exchangeable common stock has rights identical to
Servicesoft's outstanding common stock and is exchangeable into shares of common
stock at any time at the option of the holder; accordingly, the exchangeable
common stock has been included within the balance of outstanding common stock.

  Series X and Y Preferred Stock

     As of December 31, 1999, Servicesoft had one share of Series X preferred
stock outstanding and one share of Series Y preferred stock outstanding which
were issued in connection with the Balisoft merger to a trustee of the former
Balisoft stockholders pursuant to a Voting and Exchange Trust Agreement. Under
this agreement, the holders of exchangeable common stock are entitled to
exercise voting rights equivalent to voting rights attaching to the same number
of Servicesoft's common stock by and through the trustee of the share of Series
X preferred stock. The holders of exchangeable preferred stock are entitled to
exercise voting rights equivalent to voting rights attaching to the same number
of shares of Series H preferred stock through the trustee of the share of Series
Y preferred stock. The share of Series X preferred stock will be automatically
redeemed at such time that no shares of exchangeable common stock are
outstanding and the share of Series Y preferred stock will be automatically
redeemed, at such time that no shares of exchangeable preferred stock are
outstanding.

  Restricted Stock

     During October and November 1999, Servicesoft granted 1,060,502 shares of
$.01 par value restricted common stock to certain employees and members of its
Board of Directors. These shares vest annually over a four-year term for those
shares issued to employees and annually over a three-year term for those shares
issued to Board of Directors members. Unvested restricted shares are subject to
forfeiture in the event that an employee ceases to be employed by Servicesoft or
a Board of Director member ceases to be on the Board of Directors. Servicesoft
recorded deferred stock compensation of $4,710,000, which represents the excess
of the fair value of the restricted shares at the date of the award, for
financial reporting purposes, over the purchase price. Compensation expense will
be recognized ratably over the vesting period of the restricted stock. For the
year ended December 31, 1999, Servicesoft recognized $323,000 of related stock
compensation expense.

     In connection with the issuance of the restricted stock, Servicesoft
accepted notes payable from two officers in the total amount of $1,013,000.
These notes have an interest rate of 7% compounded annually; interest is payable
annually on the anniversary date of the notes. The principal and any accrued but
unpaid interest is payable on the earlier of the sale or other disposition of
the underlying stock or on the tenth anniversary of the notes. The principal and
interest may not be prepaid. Interest earned during the year

ended December 31, 1999 was $11,000 and is included in interest income. These
notes are secured by the underlying shares of stock and have recourse to the
officers' personal assets of up to 30% of the principal amount and 100% of any
outstanding interest.

  Stock Option Modifications

     In August 1999, a former employee of Servicesoft exercised stock options to
purchase 368,122 shares of common stock, through the issuance of a recourse note
payable to Servicesoft in the amount of $68,000. This note has an interest rate
of 6% and is due on the earlier of (i) the third anniversary of issuance, (ii)
one year after completion of an initial public offering of common stock or (iii)
upon the sale or disposition of the underlying stock. Interest earned during the
year ended December 31, 1999 was $2,000 and is included in interest income. As a
result of modifying these options, Servicesoft recorded stock compensation
expense of $1,036,000 during the year ended December 31, 1999.

     During 1999, Servicesoft also authorized other stock option modifications,
such as extended exercise periods, which resulted in the recording of $217,000
of additional stock compensation expense during the year ended December 31,
1999.

  Common Stock Purchase Warrants

     As of December 31, 1999, Servicesoft had warrants outstanding for the
purchase of 2,797 shares of common stock. These warrants, which were issued in
connection with services rendered, were immediately exercisable and expire in
the year 2003. The holder of these warrants may purchase 2,634 shares of common
stock at $0.18 per share and 163 shares of common stock at $7.36 per share.
These warrants were determined to have an immaterial value on the date of issue.

     As part of the Balisoft acquisition, Servicesoft issued warrants for the
purchase of 77,855 shares of exchangeable common stock at a price of $3.53 per
share. These warrants were immediately exercisable and expire in June 2000.

     As part of the IBA acquisition, Servicesoft issued warrants for the
purchase of 17,985 shares of common stock. These warrants were immediately
exercisable at a price of $4.10 per share and expire on December 17, 2004. The
value of these warrants has been included in the purchase price of IBA (Note 3).

     As of December 31, 1999, Servicesoft had 2,304,552 shares of common stock
reserved for issuance upon the exchange of the exchangeable common stock and the
exercise of outstanding common stock warrants.

  Bridge Loan Conversion

     During 1996 and 1997, Servicesoft received proceeds of approximately
$724,000 and $782,000, respectively, from the issuance of bridge loans. As of
December 31, 1997, accrued interest related to these loans was $83,000. The
terms of the bridge loans included an interest rate of 8% and an original
maturity date of November 14, 1997. On February 18, 1998, Servicesoft converted
all amounts outstanding under the bridge loan, including accrued interest, into
2,118,735 shares of Series F preferred stock at a value of $0.75 per share.
Associated with this conversion, Servicesoft recorded an additional $530,000 of
interest expense to reflect the issuance of Series F preferred stock at below
fair market value.

7. STOCK OPTION PLAN:

     In accordance with Servicesoft's 1994 Stock Option Plan (the "94 Plan"), as
amended, incentive stock options ("ISOs") and nonqualified stock options to
purchase a maximum of 2,200,000 shares of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

common stock may be granted to qualified individuals by Servicesoft's Board of
Directors. On November 1, 1999, Servicesoft adopted the 1999 Stock Option and
Grant Plan (the "99 Plan"). The 99 Plan provides for the granting of ISOs and
nonqualified stock options, restricted stock awards and unrestricted stock
awards to officers, employees, directors, consultants, advisors and other key
persons, for up to 1,876,498 shares of common stock. The 99 Plan provides that
upon an initial public offering of Servicesoft's common stock and on each
January 1 beginning on January 1, 2001, the number of reserved shares authorized
under the 99 Plan will automatically increase to equal the greater of 4% of the
issued and outstanding capital stock on a fully-diluted basis or that number of
shares as would be necessary to maintain the reserved number of shares at 20% of
the issued and outstanding capital stock on a fully-diluted basis. ISOs are
granted to employees of Servicesoft with exercise prices not less than the fair
market value of Servicesoft's common shares on the date of grant, as determined
by Servicesoft's Board of Directors, typically vest over a four-year period, and
are exercisable over a period not to exceed ten years from the date of grant.
Nonqualified options may be granted to employees, directors, consultants and
other advisors to Servicesoft on terms set forth by the Board of Directors on an
individual case basis.

     The following table summarizes activity of the 94 Plan and the 99 Plan
since January 1, 1997:

weighted-average exercise prices of $1.73, $1.19 and $0.75, respectively. The
weighted average fair value per share of options granted during 1997, 1998 and
1999 was $0.03, $0.12 and $5.18, respectively.

     As of December 31, 1999, 100,215 and 797,603 shares were available for

     Under APB 25, prior to 1999, no compensation expense had been recognized
for stock option grants made by Servicesoft. For the year ended December 31,
1999, compensation expense recognized for stock option and restricted stock
grants totaled $1,900,000. Had compensation cost for Servicesoft's stock option
plans been determined based on the fair value at the date of grant for awards
granted in 1999 and all prior periods (excluding those common stock options
converted and issued in connection with the Balisoft and IBA transactions),
consistent with the provisions of SFAS 123, Servicesoft's net loss attributable

     For this purpose, the fair value of options at the date of grant was
estimated using the minimum value method with the following weighted-average
assumptions for 1997, 1998 and 1999: risk-free interest rates of 6.5%, 5.0% and
5.25%, respectively; no dividend yields or volatility factors; and
weighted-average expected life of the options of five years. However, because
most options vest over periods of up to four years and because additional option
grants are expected to be made subsequent to December 31, 1999, the pro forma
effects of applying the fair value method may be materially different in future
years.

     [Unaudited] For the six months ended June 30, 2000, Servicesoft issued
options to purchase 1,575,541 shares of common stock at various exercise prices
resulting in deferred compensation of $5,741,000, which has been recorded as of
the option issuance dates. Such deferred compensation is being amortized to
expense over the vesting term of the options, generally four years.

8. LINES OF CREDIT:

  Revolving Line of Credit

     On June 3, 1999, Servicesoft entered into a revolving credit facility with
a bank which provides up to $2,000,000 in revolving credit. Under the terms of
this agreement, Servicesoft paid a non-refundable facility fee of $3,750 and
must pay on the first date of each calendar quarter thereafter a non-refundable

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

facility fee in the amount of $2,500. The interest rate assessed on outstanding
borrowings is equal to the bank's prime rate plus 0.5% per year (9.0% at
December 31, 1999). Additionally, Servicesoft is required to maintain certain
financial ratios and is bound by covenants over the life of the agreement. As of
December 31, 1999, Servicesoft had $1,000,000 outstanding under this facility
and $1,000,000 remained available.

  Equipment Line

     On June 3, 1999, Servicesoft entered into equipment financing arrangements
with a bank for aggregate borrowings of $750,000 with an interest rate of the
bank's prime rate plus 0.75% per year (9.25% at December 31, 1999). Borrowings
are collateralized by certain assets of Servicesoft. Servicesoft had no
borrowings against this facility as of December 31, 1999.

9. COMMITMENTS:

  Operating Leases

     Servicesoft has entered into operating leases for its office facilities and
certain equipment, which expire at various dates through 2005. Total rent
expense for the years ended December 31, 1997, 1998 and 1999 was $162,000,
$157,000 and $818,000, respectively.

  Capital Leases

     Servicesoft has entered into various lease agreements for computer and
office equipment and software that have been recorded as capital leases. Certain
of these leases required Servicesoft to deposit restricted cash on account of
$187,000 as of December 31, 1999; other capital leases required Servicesoft to
obtain $400,000 of standby letters of credit. Servicesoft would be required to
reimburse the bank for any amounts paid under these letters of credit.

     Future minimum lease payments under all noncancelable operating and capital
leases as of December 31, 1999 were as follows (in thousands):

carryforwards expire in the years 2000 through 2019, and are subject to
additional annual limitations as a result of changes in Servicesoft's ownership.

     Management of Servicesoft has evaluated the positive and negative evidence
bearing upon the realizability of its deferred tax assets. Through December 31,
1999, management was unable to conclude that it is more likely than not that
Servicesoft will realize the benefit of the deferred tax assets and,
accordingly, Servicesoft has recorded a valuation allowance for the full amount
of the net deferred tax assets.

12. SAVINGS PLAN:

     Servicesoft sponsors a savings plan for its employees which is designed to
be qualified under section 401(k) of the Internal Revenue Code. Eligible
employees are permitted to contribute to the 401(k) plan through payroll
deductions within statutory and plan limits. Servicesoft does not contribute to
the plan.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Directors of
Balisoft Technologies Inc.

     We have audited the consolidated balance sheets of Balisoft Technologies
Inc. as at December 31, 1998 and 1997 and the consolidated statements of loss
and deficit and changes in financial position for the year ended December 31,
1998 and for the period from the date of incorporation, June 5, 1997, to
December 31, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in Canada. Those standards require that we plan and perform an audit to
obtain reasonable assurance whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation.

     In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the Company as at December 31,
1998 and 1997 and the results of its operations and the changes in its financial
position for the year ended December 31, 1998 and for the period from the date
of incorporation, June 5, 1997, to December 31, 1997 in accordance with
accounting principles generally accepted in Canada.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         (AMOUNTS IN CANADIAN DOLLARS)

1. SIGNIFICANT ACCOUNTING POLICIES

     The consolidated financial statements of Balisoft Technologies Inc. [the
"Company"] have been prepared by management in accordance with generally
accepted accounting principles in Canada. The significant accounting policies
are as follows:

  Basis of consolidation

     These consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary, Balisoft Ltd., incorporated under the laws of
Israel. These consolidated financial statements are expressed in Canadian
dollars, the operating currency of the Company.

  Use of estimates

     In preparing the Company's consolidated financial statements, management is
required to make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the consolidated financial statements and reported amounts of
revenue and expenses during the period. Actual results may differ from these
estimates.

  Cash and cash equivalents

     Cash includes cash equivalents, which are investments that are generally
held to maturity and have terms of three months or less at the time of
acquisition. Cash equivalents typically consist of discounted and short-term
notes. Cash equivalents are stated at fair value, which approximates cost.

  Capital assets

     Capital assets are recorded at cost less accumulated amortization.
Amortization is provided on a straight-line basis over the following periods:

<TABLE>
<S>                                                      <C>
Office equipment.......................................  5 years
Computer hardware and software.........................  3 years
Furniture and fixtures.................................  6 to 15 years
Motor vehicles.........................................  6.67 years
Leasehold improvements.................................  5 years
Equipment under capital leases.........................  3 years
</TABLE>

  Leases

     A lease that transfers substantially all the benefits and risks incidental
to the ownership of the property is accounted for as if it were an acquisition
of an asset and the incurrence of an obligation at the inception of the lease.
All other leases are accounted for as operating leases with rental payments
being expensed as incurred.

  Revenue recognition

     Revenue from software sales is recognized on delivery of the software.

  Foreign exchange translation

     The Company's subsidiary is considered to be an integrated operation.
Accordingly, monetary assets and liabilities denominated in foreign currencies
are translated into Canadian dollars at the rates of

                                      F-29

exchange prevailing at period end while other consolidated balance sheet items
are translated at historic rates. Revenue and expenses are translated at the
rates of exchange in effect on the transaction dates. Realized and unrealized
foreign exchange gains and losses are included in income in the period in which
they occur, except where they arise from translation of non-current monetary
items. Such gains and losses are deferred and amortized to income on a
straight-line basis over the remaining life of the underlying non-current
monetary items.

  Research and development

     Research costs are expensed in the period incurred. Development costs are
expensed in the period incurred unless a development project meets generally
accepted accounting criteria for deferral and amortization. No development costs
have been deferred to date.

  Income taxes

     The Company follows the deferral method of income tax allocation. Deferred
income taxes result from claiming deductions for income tax purposes in amounts
which differ from those charged in the accounts.

2. CASH EQUIVALENTS

     As at December 31, 1998, cash equivalents consist of bankers' acceptances
of U.S. $2,604,090 and $2,372,496 [$995,960 at December 31, 1997], which mature
on January 15, 1999 and January 20, 1999, respectively [January 21, 1998 for
December 31, 1997], and bear interest at rates ranging from 4.3% to 4.4%.

3. CAPITAL ASSETS

     The Canada Israel Industrial Research and Development Foundation ["CIIRDF"]
has advanced $200,000 of a total $600,000 due under the terms of an agreement
with the Company and its subsidiary, dated November 24, 1997. The balance of the
monies was due in two equal annual tranches on November 24, 1998 and 1999,
however, owing to the discontinuance of operations of the subsidiary, no further
amounts will be advanced. The provisions of the agreement require repayment of
the loan at 2.5% of gross sales, calculated semi-annually commencing at the date
of the first commercial transaction. The loan will be forgiven in the event that
no commercial sales of the products funded by CIIRDF are made. No interest is
charged on this loan.

     The U.S. dollar loan from Bank Leumi is collateralized against certain
assets of the subsidiary, bears interest at 8.5% per annum and is repayable in
monthly installments of U.S. $331.

     The common shares and preferred shares participate equally with respect to
voting rights. Any preferred shares which may be issued shall rank prior to the
common shares with respect to dividends and with respect to the return of
property or assets upon the liquidation, dissolution or winding-up of the
Company. After the payment of preferred share dividends, the preferred shares
participate equally with the common shares in any further dividends.

     The preferred shares may be converted pro rata, at any time, at the option
of the holder, into fully paid, non-accessible common shares of the Company on a
one-for-one basis. Each outstanding preferred share shall be automatically
converted into one common share at the earlier of June 1, 2002, any initial
public offering of common shares of the Company, or the closing date of a change
of control transaction.

     [a] Warrants.  On April 9, 1998, 250 common shares were issued for
aggregate proceeds of approximately $14,300 [U.S. $10,000]. In connection with
this issue of common shares, the Company granted 5,000 warrants that are
exercisable at any time up to June 3, 2000, at an exercise price of U.S. $54.92.

     [b] Special warrants.  Pursuant to an agreement dated June 3, 1998, the
Company completed the issuance, by way of a private placement, of 112,013
special warrants for gross proceeds of $8,851,000 [U.S. $5,700,000 and Cdn.
$650,000]. The net proceeds of the offering totalled approximately $8,631,439.

     Each special warrant [other than 1,898 special warrants that are
convertible into common shares only] is exercisable without additional
consideration for one preferred share or, at the election of the holder, such a
number of common shares as would be issuable upon conversion of one preferred
share into common shares in accordance with the Articles of Incorporation.

     In the event that a final prospectus is not issued and the Company fails to
complete an initial public offering on or before the 3rd anniversary date of the
agreement, any special warrants exercised after this date shall entitle the
holders to receive 1.15 shares, without payment of additional consideration. Any
outstanding warrants shall be deemed to have been exercised by the holder on the
expiry date, being the 4th anniversary of the closing date.

     [c] Exchangeable preferred shares.  On June 3, 1998, the Company issued 100
exchangeable preferred shares in its subsidiary for aggregate proceeds of
approximately $2,877,600 [U.S. $2,000,000], to be used specifically to fund
research and development. The associated costs of the exchangeable preferred
share issue were approximately $75,500.

     These exchangeable preferred shares are exchangeable on the basis of
364.16605 preferred shares or 364.16605 common shares of the Company at the
holder's option for each exchangeable preferred share subject to adjustment as
set forth in the Articles of Incorporation and share exchange agreement. The
exchangeable preferred shares rank equally with the common shares of the Company
in respect of voting rights and entitlement to dividends. Upon liquidation,
proceeds will be allocated U.S. $54.92 plus 8% interest from June 1, 1998 to
each issued preferred share and then U.S. $54.92 to each common share. The
common and preferred shares then share equally in any remaining liquidation
surplus.

                         (AMOUNTS IN CANADIAN DOLLARS)

     An automatic exchange of the exchangeable preferred shares into either
common or preferred shares may occur if any of the following transactions takes
place:

     [i]  Upon insolvency of the Company or the subsidiary;

     [ii]  Upon the proposed sale of all or substantially all, or the proposed
           amalgamation, merger or other business combination of the subsidiary;

     [iii] From June 3, 2003, after a resolution of the board of directors of
           the subsidiary; or

     [iv] Upon a mandatory conversion event defined in the Articles of Amendment
          as either the closing date of any initial public offering by the
          Company or the closing date of any transaction approved by the board
          of directors of the Company in a resolution designating such
          transaction as a "change in control transaction" for the purposes of
          the Articles of Amendment and resulting in the acquisition of control
          of the Company, the sale of all or substantially all of the business
          or assets of the Company, or the amalgamation, merger or other
          business combination of the Company.

     Accordingly, the preferred shares of the subsidiary held by non-controlling
interests is regarded in substance as a residual equity interest of the Company
and has been presented as equity in these consolidated financial statements.

     [d] Stock options.  As at December 31, 1998, 10,000 founder's options are
outstanding to acquire 10,000 common shares at an exercise price per common
share of $0.01 which expire on April 6, 2007.

     The Company has established two stock option plans [Option Plan A and
Option Plan B] to encourage ownership in the Company's common shares by
executives, directors and employees of the Company and its subsidiary. As at
December 31, 1998, under these plans there were options granted to purchase
32,525 common shares exercisable at various prices which range from Cdn. $0.10
to $55.00 and U.S. $1.00 to $40.00. These options expire on various dates to
April 29, 2001.

10. RECONCILIATION OF GENERALLY ACCEPTED ACCOUNTING PRINCIPLES

     The Company prepares its consolidated financial statements in accordance
with accounting principles generally accepted in Canada ["Canadian GAAP"],
which, as applied in these consolidated financial statements, conform in all
material respects to those accounting principles generally accepted in the

     Under Canadian GAAP, the accompanying consolidated statements of changes in
financial position report the changes in financial position of each major
balance sheet item, reconciling to the net change in cash. Under U.S. GAAP, the

11. UNCERTAINTY DUE TO THE YEAR 2000 ISSUE

     The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
year 2000 dates is processed. In addition, similar problems may arise in some
systems which use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 Issue may be experienced before, on, or after
January 1, 2000, and, if not addressed, the impact on operations and financial
reporting may range from minor errors to significant systems failure which could
affect an entity's ability to conduct normal business operations. It is not
possible to be certain that

fully resolved.

12. SUBSEQUENT EVENT

     Subsequent to December 31, 1998, in February 1999, the Company entered into
a combination transaction with a U.S. based company, ServiceSoft Corporation.
The shareholders of the Company received 45% of the common and preferred share
equity in the new combined entity. As part of the transaction, the Company
merged with Servicesoft Technologies (Canada) Inc., a wholly-owned subsidiary of
ServiceSoft Corporation. As part of the terms, 20% of the exchangeable shares of
Servicesoft Technologies (Canada) Inc. and 20% of ServiceSoft Corporation's
shares have been placed in escrow until the earlier of completion of an initial
public offering or 60 days after the completion of the fiscal 1999 audit.

                         NOTES TO FINANCIAL STATEMENTS

1. NATURE OF THE BUSINESS AND BASIS OF PRESENTATION

     Internet Business Advantages, Inc. ("IBA") is a professional service
consulting and systems firm. IBA's principal market is domestic businesses. IBA
manages its business as a single segment.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Cash Equivalents

     IBA invests its excess cash primarily in money market funds of major
financial institutions. These investments are subject to minimal credit and
market risk. IBA considers all highly liquid investments with original
maturities of three months or less to be cash equivalents. Cash equivalent
investments are classified as available-for-sale and carried at cost, which
approximates fair market value.

  Fair Value of Financial Instruments

     The carrying amount of IBA's financial instruments, which include cash and
cash equivalents, accounts receivable, accounts payable, accrued expenses and
long-term debt, approximate their fair values at December 31, 1997 and 1998.

  Revenue Recognition

     IBA receives fees for application development and consulting which
constitute the majority of IBA's revenue. Revenue is recognized using the
percentage-of-completion method based on the ratio that the hours expended to
date bears to the estimated total hours at completion. Losses, if any, are
provided for at the time that management determines costs will exceed fees.
Maintenance contract revenue is deferred and recognized ratably over the
contract period, generally six months or less. Unbilled accounts receivable
represents revenue recognized in excess of amounts billed. Deferred revenue
represents the unrecognized portion of maintenance contract revenue and amounts
billed in excess of revenue recognized on application development and consulting
contracts.

  Concentration of Credit Risk and Significant Customers

     Financial instruments which potentially expose IBA to concentrations of
credit risk consist primarily of trade accounts receivable. Management believes
its credit policies are prudent and reflect normal industry terms and business
risk. IBA performs ongoing credit evaluations of customers' financial condition
but does not require collateral. IBA maintains reserves for potential credit
losses and such losses, in the aggregate, have not exceeded management's
expectations.

     At December 31, 1997, four customers accounted for 27%, 22%, 16% and 12% of
total accounts receivable. At December 31, 1998, four customers accounted for
27%, 24%, 19% and 14% of total accounts receivable.

     Revenue from three customers accounted for 28%, 19% and 15% of total
revenue for the year ended December 31, 1997. Revenue from one customer
accounted for 32% of total revenue for the year ended December 31, 1998.

  Fixed Assets

     Fixed assets are recorded at cost and depreciated using the straight-line
method over the estimated useful lives of the assets. Repair and maintenance
costs are expensed as incurred.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Stock-Based Compensation

     IBA accounts for stock-based awards to employees in accordance with
Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued
to Employees," and related interpretations. IBA has adopted the provisions of
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation," through footnote disclosure only.

  Advertising Costs

     Advertising costs are expensed as incurred. Advertising costs were $33,000
and $17,000 in the years ended December 31, 1997 and 1998.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual amounts could differ from those estimates.

  Recently Issued Accounting Pronouncements

     In February 1998, the Accounting Standards Executive Committee ("AcSEC")
issued Statement of Position ("SoP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." SoP 98-1 establishes the
accounting for costs of software products developed or purchased for internal
use, including when such costs should be capitalized. SoP 98-1 will be effective
for IBA beginning in 1999, and IBA does not expect adoption of this SoP to have
a material effect on its financial position or results of operations.

     In April 1998, the AcSEC issued SoP 98-5, "Reporting on the Costs of
Start-Up Activities." Start-up activities are defined broadly as those one-time
activities related to the opening of a new facility, introducing a new product
or service, conducting business in a new territory, conducting business with a
new class of customer, commencing some new operation or organizing a new entity.
SoP 98-5 requires that the cost of start-up activities be expensed as incurred.
SoP 98-5 is effective for IBA beginning in 1999 and IBA does not expect adoption
of this SoP to have a material effect on its financial position or results of
operations.

3. INVESTMENT IN INTERNET SECURITY ADVANTAGES, INC. AND GAIN ON DISPOSAL OF
   SUBSIDIARY

     In November 1997, IBA and Axent Technologies, Inc. ("Axent") established
Internet Security Advantages, Inc. ("ISA"), a joint venture, to provide Internet
network security consulting services. Axent contributed $50,000 for the purchase
of 50,000 shares of common stock, or 5% ownership. IBA contributed its
capability to manage consulting services ("Know-how") in exchange for 950,000
shares of common stock, or 95% ownership. In addition, ISA entered into a term
loan agreement with Axent which enabled ISA to borrow up to $950,000 through
November 1998. At December 31, 1998, ISA had borrowed $350,000. Axent may
convert all or any portion of the principal at any time into shares of ISA
common stock in accordance with a formula in the term loan agreement. The joint
venture also authorized 600,000 shares of common stock for issuance under
restricted stock and stock option plans and 100,000 shares of preferred stock.
At December 31, 1998, no shares of restricted stock, stock options or preferred
stock had been issued. IBA accounts for such investment in accordance with the
equity method as Axent holds certain participating rights over operating and
capital decisions.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     IBA's initial investment in ISA was recorded at zero. The difference
between the carrying amount of the investment and IBA's share of the underlying
equity in net assets of ISA represents a deferred gain, which is being amortized
to equity income (loss) over seven years, the estimated life of the Know-how
contributed to ISA at the inception of the joint venture. The amount of the
deferred gain at the inception of ISA was $47,500, and at December 31, 1997 and
1998, the unamortized portion of the deferred gain is approximately $46,400 and
$39,600, respectively. At December 31, 1997 and 1998, IBA recognized a liability
for its proportionate share of ISA's losses, net of amortization of the deferred
gain, in excess of the carrying amount of the investment as ISA's losses are
primarily attributable to start-up costs and profitable operations are expected.

     The equity loss from investment in affiliate and the accumulated losses
from investment in affiliate would not have been materially different from the
reported amounts at December 31, 1997 and 1998 and for the years then ended, if
Axent had converted the term loan into ISA common stock.

     Condensed financial information of ISA at December 31, 1997 and 1998 and
for the period from inception (November 10, 1997) through December 31, 1997 and
the year ended December 31, 1998 is summarized below:

</TABLE>

     Unaudited -- In May 1999, IBA acquired Axent's 5% interest in the assets
and liabilities of ISA for total cash consideration of $50,000. IBA accounted
for the acquisition of Axent's interest under the purchase method of accounting
and allocated the purchase price to the assets acquired and liabilities assumed
based on their fair values at the date of acquisition. Following the acquisition
of Axent's interest, IBA has accounted for ISA as a 100% owned and consolidated
subsidiary.

     Unaudited -- In August 1999, IBA disposed of ISA for $600,000 in cash. The
difference between the total cash consideration received and the net book value
of the assets disposed was recorded as gain on disposal of ISA in the nine
months ended September 30, 1999.

5. LINES OF CREDIT

     In October 1998, IBA entered into an agreement with a bank under which IBA
has the ability to borrow up to $750,000 for working capital purposes ("Working
Capital Facility") and $500,000 for purchases of equipment and software
("Equipment Facility"), subject to certain limitations. All borrowings under
this agreement are collateralized by substantially all of IBA's assets and bear
interest at the bank's prime rate plus 0.50% (8.25% at December 31, 1998).
Borrowings against the Working Capital Facility and accrued interest are due and
payable by November 1, 1999. As of December 31, 1998, no borrowings had been
made against the Working Capital Facility. Accrued interest on Equipment
Facility advances will be payable monthly through August 1, 1999. Equipment
Facility advances outstanding on August 1, 1999 will convert to a term loan to
be repaid in 36 equal monthly installments of principal, plus accrued interest.
Borrowings against the Equipment Facility totaled $133,363 at December 31, 1998.
In addition, IBA is required to comply with certain restrictive covenants,
including the maintenance of specific financial ratios. As of December 31, 1998,
IBA was in compliance with all financial and nonfinancial covenants.

     In May 1999, IBA entered into a $500,000 term note agreement bearing
interest at the bank's prime rate plus 1.0%. The term note is due in May 2002
and is secured by substantially all of IBA's assets and requires IBA to comply
with certain financial and nonfinancial covenants.

  Convertible Demand Note

     In March 1999, IBA obtained debt financing in the form of convertible
demand notes ("Demand Notes") totaling $2,200,000 from shareholders of IBA. The
Demand Notes bear interest at an annual interest rate of 6.5% and are
convertible into Series D redeemable convertible preferred stock ("Series D
Preferred Stock") at the issuance price. If the Series D Preferred Stock is not
issued within nine months of the Demand Notes, the principal and accrued
interest balances will be payable in full. In connection with the Demand Notes,
IBA issued warrants to investors for the purchase of $550,000 in shares of
Series D Preferred Stock at the issuance price. Should the Series D Preferred
Stock not be issued within nine months of the debt financing, the warrants will
become convertible into 167,683 shares of Series C redeemable convertible
preferred stock at $3.28 per share. The warrants are exercisable for a period of
four years.

6. REDEEMABLE CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' DEFICIT

  Redeemable Convertible Preferred Stock

     The Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock (collectively, the "Redeemable Convertible Preferred Stock")
have the following characteristics:

          Conversion.  Each share of the Redeemable Convertible Preferred Stock
     is convertible at any time at the option of the holder into one share of
     common stock, subject to certain anti-dilution adjustments, except that
     holders of the Series B Preferred Stock may only opt for conversion upon
     either (i) the closing of an initial public offering of IBA's common stock
     or (ii) the sale of all or substantially all of the assets of IBA. All
     shares of the Redeemable Convertible Preferred Stock automatically convert
     into common stock upon the closing of a public offering of IBA's common
     stock involving aggregate proceeds to IBA of at least $15 million and a
     price of not less than $9.00 per share.

          At December 31, 1998, IBA has reserved 4,999,998 shares of its common
     stock for issuance upon conversion of the Redeemable Convertible Preferred
     Stock.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

          Dividend Rights.  Holders of the Redeemable Convertible Preferred
     Stock are entitled to receive dividends when and if declared by the Board
     of Directors. Any dividends declared must be distributed to the holders of
     each series of the Redeemable Convertible Preferred Stock equally and no
     dividends may be paid on the common stock until any and all dividends
     declared on the Redeemable Convertible Preferred Stock have been paid in
     full. Through December 31, 1998, no dividends have been declared or paid by
     IBA.

          Redemption.  At the request of the holders of a majority of the Series
     A Preferred Stock, on December 31, 2003 and each anniversary thereafter,
     IBA shall redeem the then outstanding shares of Series A Preferred Stock
     held by the requesting shareholders at a per share price of $1.10 plus all
     declared but unpaid dividends, subject to certain anti-dilution
     adjustments. The Series B Preferred Stock and Series C Preferred Stock are
     redeemable under the same terms as the Series A Preferred Stock except that
     they are redeemable at a per share price of $0.91 and $3.28, respectively,
     plus all declared but unpaid dividends, subject to certain anti-dilution
     adjustments.

          Liquidation, Dissolution or Winding-Up.  In the event of any
     liquidation, dissolution or winding-up of the affairs of IBA, the holders
     of the then outstanding Series A Preferred Stock, Series B Preferred Stock
     and Series C Preferred Stock will be entitled to receive, in preference to
     the holders of the common stock, a payment of $1.10, $0.91 and $3.28 per
     share, respectively, plus any declared but unpaid dividends. Any assets
     remaining following the distributions to the holders of the Redeemable
     Convertible Preferred Stock will be distributed ratably among the common
     stockholders.

          Voting Rights.  Each holder of the Series A Preferred Stock and Series
     C Preferred Stock is entitled to the number of votes equal to the number of
     shares of common stock into which such holder's shares are convertible at
     the record date for such vote. Holders of the Series B Preferred Stock are
     not entitled to vote on the affairs of IBA.

  Stock Restriction Agreements

     At December 31, 1997 and 1998, all of IBA's outstanding shares of common
stock were subject to stock restriction agreements. Under these agreements, IBA
has the option to repurchase any or all unvested shares of common stock held by
a given stockholder in the event of voluntary resignation or termination of
their employment by IBA. The number of shares that may be repurchased by IBA
upon termination is reduced over a four-year period. At December 31, 1998,
125,000, 7,000 and 120,000 shares of common stock are subject to repurchase at a
price of $0.001, $0.05 and $0.01 per share, respectively.

  Treasury Stock

     During 1998, IBA repurchased 178,875 shares of common stock at cost.

7. 1996 STOCK PLAN

     During 1996, IBA adopted the 1996 Stock Incentive Plan (the "1996 Plan").
The 1996 Plan provides for the granting of incentive and non-qualified stock
options, performance shares, restricted stock and other stock-based awards to
management, other key employees, consultants and directors of IBA. The total
number of shares of common stock that may be issued pursuant to awards granted
under the 1996 Plan is 466,667. The exercise price under each stock option shall
be specified by the Board of Directors at the time of grant. However, incentive
stock options may not be granted at less than the fair market value of IBA's
common stock at the date of grant or for a term in excess of ten years. For
holders of more than 10% of IBA's total combined voting power of all classes of
stock, incentive stock options may not be granted at less than 110% of the fair
market value of IBA's common stock at the date of grant and for a term not to
exceed five years.

</TABLE>

     At December 31, 1998, no options were exercisable. The weighted average
remaining contractual life of options granted in 1998 is 9.63 years.

  Fair Value Disclosures

     No compensation cost has been recognized under APB Opinion No. 25 for
options granted to employees during the year ended December 31, 1998. Had
compensation costs for these awards been determined based on the fair value at
the date of grant consistent with the method prescribed by SFAS No. 123, IBA's
net loss for the year ended December 31, 1998 would not have differed
significantly from the amount reported. However, because options vest over
several years and because additional option grants are expected to be made
subsequent to December 31, 1998, the pro forma effects of applying the fair
value method may be material to reported net income or loss in future years.

     The fair value of each option grant is estimated on the date of grant using
the minimum value option-pricing method with the following assumptions used for
option grants made in 1998: no dividend yield, risk-free interest rate of 5.0%,
no volatility and an expected option term of five years.

8. INCOME TAXES

     Deferred tax assets consist of the following:

     At December 31, 1997 and 1998, IBA has provided a valuation allowance for
the full amount of the deferred tax assets since realization of any future
benefit from deductible temporary differences and net operating loss and tax
credit carryforwards cannot be sufficiently assured.

     At December 31, 1998, IBA has net operating loss carryforwards for federal
and state tax purposes of approximately $3,940,000 which are available to reduce
future taxable income and expire at various dates through 2018. IBA also has
federal and state investment tax credit carryforwards of $19,000 and $25,000,

respectively, available to reduce future tax liabilities. These tax credit
carryforwards expire at various dates between 2011 and 2013.

     Under the provisions of the Internal Revenue Code, certain substantial
changes in IBA's ownership may limit the amount of net operating loss and tax
credit carryforwards which could be utilized annually to offset future taxable
income and taxes payable. The amount of this annual limitation is determined
based, in part, upon IBA's value prior to an ownership change.

                              FINANCIAL STATEMENTS

     During the year ended December 31, 1999, Servicesoft, Inc. ("Servicesoft")
completed two transactions which are comprehended by these unaudited pro forma
combined financial statements.

BALISOFT TECHNOLOGIES INC.

     On February 12, 1999, Servicesoft completed its merger with Balisoft
Technologies Inc. ("Balisoft"), a company that develops e-mail management and
real-time internet collaboration applications. In connection with the
acquisition, Servicesoft issued 2,205,915 shares of exchangeable common stock
valued at $3,760,000, issued 2,281,653 shares of exchangeable preferred stock
(exchangeable into Series H redeemable convertible preferred stock) valued at
$7,773,000, and assumed or issued options and warrants to purchase 641,275
shares of Servicesoft common stock valued at $780,000. Servicesoft valued the
options and warrants included in the purchase consideration based on a Black
Scholes computation of their fair value at the date of grant; assumptions used
included a risk-free interest rate of 5.25%, no dividend yield, volatility of
100%, weighted average expected life of 5 years, and fair value of the
underlying common stock of $1.70 per share. The total consideration of

based on an independent appraisal. In connection with this merger, Servicesoft
incurred costs of $273,000, which are included in the total purchase price for
accounting purposes.

     The merger was accounted for under the purchase method of accounting.
Accordingly, the fair market values of the acquired assets and assumed
liabilities have been included in the consolidated financial statements of
Servicesoft as of the merger date and the results of operations of Balisoft have
been included thereafter. The purchase price was allocated to the acquired
assets and assumed liabilities as follows (in thousands):

UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS

     The unaudited pro forma combined statement of operations for the year ended
December 31, 1999 presents the results of operations of Servicesoft, Balisoft
and IBA on a combined basis assuming the acquisitions had occurred on January 1,
1999. The transactions were accounted for under the purchase method;
accordingly, the results of operations of Balisoft and IBA were included in the
results of Servicesoft as reported from the applicable closing dates. The pro
forma columns for Balisoft and IBA represent their results of operations in 1999
prior to the transactions. All material adjustments to reflect the effects of
the transactions are set forth in the Adjustments column. An unaudited pro forma
combined balance sheet is not presented here since all effects of the
transactions are reflected in the consolidated balance sheet of Servicesoft as
of December 31, 1999, which is presented elsewhere herein.

     The pro forma data is for informational purposes only and does not
necessarily reflect future results of operations or what the results of
operations would have been had Servicesoft, Balisoft, and IBA been operating as
a combined entity for the specified period. The unaudited pro forma combined
financial statements should be read in conjunction with the historical
consolidated financial statements of Servicesoft, including the notes thereto.

(c) The calculation of pro forma weighted-average number of shares outstanding
    includes the weighted-average number of common shares outstanding of
    Servicesoft for the year ended December 31, 1999, adjusted to give effect to
    the issuance of 2,205,915 shares of Servicesoft's common stock in connection
    with the Balisoft merger and the issuance of 1,124,010 shares of
    Servicesoft's common stock in connection with the IBA acquisition, as if
    such shares had been outstanding since January 1, 1999. The calculation does
    not include the effect of common stock equivalents as their inclusion would
    be anti-dilutive.

shall be the time of filing of the Certificate of Merger unless otherwise
specified in the Certificate of Merger. On the terms and subject to the
conditions of this Agreement and the Certificate of Merger, at the Effective
Time, Newco will be merged with and into Servicesoft (such remaining entity, as
appropriate, the "Surviving Corporation") in a statutory merger pursuant to the
Certificate of Merger and in accordance with applicable provisions of Delaware
Law as follows:

          (a) Conversion of Servicesoft Securities.

          (i) Conversion of Servicesoft Shares. On the terms and subject to the
     conditions of this Agreement, at the Effective Time, (i) each share of
     Servicesoft Common Stock and Servicesoft Preferred Stock that is issued and
     outstanding immediately prior to the Effective Time, including shares of
     Servicesoft Common Stock or Servicesoft Preferred Stock issued or issuable
     upon the exchange of Servicesoft Canada Common Stock and Servicesoft Canada
     Preferred Stock, but excluding any Dissenting Shares (as defined in Section
     2.1(a)(ii)) and any shares of Servicesoft Series X Preferred Stock and

     Series X Preferred Stock and Servicesoft Series Y Preferred Stock that

                                       A-3
<PAGE>   220

     is issued and outstanding immediately prior to the Effective Time shall be
     redeemed for a redemption price of $1.00.

          (ii) Dissenting Shares. Holders of shares of Servicesoft's capital
     stock who have duly complied with all requirements for perfecting
     stockholders' rights of appraisal, as set forth in Section 262 of the
     Delaware General Corporation Law ("Delaware Law"), shall be entitled to
     their rights under the Delaware Law with respect to such shares
     ("Dissenting Shares").

          (iii) Assumption and Conversion of Servicesoft Options and Restricted
     Stock.

          (A) Effective at the Effective Time, Broadbase will assume all
     outstanding Servicesoft Options, and each of the Servicesoft Options shall
     by its terms be converted into an option to purchase that number of shares
     of Broadbase common stock (a "Broadbase Option") which equals the number of
     shares of Servicesoft Common Stock issuable pursuant to such Servicesoft
     Option immediately prior to the Effective Time, multiplied by the
     Conversion Ratio, rounded down to the nearest whole share. The per share
     exercise price for each Broadbase Option will equal the per share exercise
     price of each such Servicesoft Option immediately prior to the Effective
     Time divided by the Conversion Ratio, rounded up to the nearest whole cent.
     No cash will be paid in lieu of fractional shares which are rounded down
     pursuant to this Section 2.1(a)(iii) (A). No Broadbase Options or Exchange
     Shares shall be issued with respect to Servicesoft Options that are
     canceled subsequent to the date of this Agreement and prior to the
     Effective Time.

          (B) Continuation Of Vesting And Repurchase Rights. If any shares of
     capital stock of Servicesoft ("SERVICESOFT CAPITAL STOCK") that are
     outstanding immediately prior to the Effective Time are unvested or are
     subject to a repurchase option, risk of forfeiture or other condition
     providing that such shares may be forfeited or repurchased by Servicesoft,
     upon any termination of a stockholder's employment, directorship or other
     relationship with Servicesoft (and/or any affiliate of Servicesoft), as the
     case may be, under the terms of any restricted stock purchase agreement or
     other agreement with Servicesoft, then the Exchange Shares issued upon the
     conversion of such shares of Servicesoft Capital Stock in the Merger will,
     subject to compliance with applicable laws, continue to be unvested and
     subject to the same repurchase options, risks of forfeiture or other
     conditions following the Effective Time, and the certificates representing
     such Exchange Shares may accordingly be marked with appropriate legends
     noting such repurchase options, risks of forfeiture or other conditions.
     Servicesoft shall take all actions that may be necessary to ensure that,
     from and after the Effective Time, Broadbase is entitled to exercise any
     such repurchase option or other right set forth in any such restricted
     stock purchase agreement or other agreement.

          (C) Terms of Assumption of Stock Options and Restricted Stock;
     Vesting. The term, exercisability, vesting schedule, status as an
     "incentive stock option" under Section 422 of the Code, if applicable, and
     all other terms of each Broadbase Option will be the same in all material
     respects as the corresponding Servicesoft Option, and no material number of
     options or shares of restricted stock will be accelerated as a result of
     the Merger, or actual or constructive termination of employment following
     the Merger, except as set forth in Item 2.1(a)(iii)(C) of the Servicesoft
     Disclosure Letter. Except as set forth in Item 2.1(a)(iii)(C) of the
     Servicesoft Disclosure Letter, no vesting of shares subject to Servicesoft
     Options, warrants or restricted stock will be accelerated as a result of
     the Merger or any event associated with the Merger and if any holder of
     Servicesoft Options, warrants or restricted stock has acceleration
     provisions that would be triggered by the Merger or any event associated
     with the Merger, Servicesoft shall cause each such holder to waive such
     acceleration provisions except for those Servicesoft Options, warrants and
     restricted stock listed in Item 2.1(a)(iii)(C) of the Servicesoft
     Disclosure Letter. Continuous employment with Servicesoft will be credited
     to holders of Broadbase Options received upon exchange of Servicesoft
     Options pursuant to Section 2.1(a)(iii)(A) for purposes of determining the
     vesting of such Broadbase Options from and after the Effective Time.

          (iv) Servicesoft Warrants and Preferred Stock.

          (A) Assumption and Conversion of Servicesoft Warrants. Effective at
     the Effective Time, Broadbase will assume all outstanding Servicesoft
     Warrants (as defined in Section 4.3(b)), and each of the Servicesoft
     Warrants shall by its terms be converted into a warrant to purchase that
     number of shares of Broadbase common stock (a "Broadbase Warrant") which
     equals the number of shares of Servicesoft Common Stock issuable pursuant
     to such Servicesoft Warrant immediately prior to the Effective Time,
     multiplied by the Conversion Ratio, rounded down to the nearest whole
     share. The per share exercise price for each Broadbase Warrant will equal
     the per share exercise price of each such Servicesoft Warrant immediately
     prior to the Effective Time divided by the Conversion Ratio, rounded up to
     the nearest whole cent. No cash will be paid in lieu of fractional shares
     which are rounded down pursuant to this Section 2.1(a)(iv). No Broadbase
     Warrants or Exchange Shares shall be issued with respect to Servicesoft
     Warrants that are canceled subsequent to the date of this Agreement and
     prior to the Effective Time.

          (B) Preferred Stock. Prior to the Closing, Servicesoft shall use all
     reasonable efforts to cause each holder of shares of Servicesoft Preferred
     Stock to convert such shares of Servicesoft Preferred Stock, effective as
     of and contingent upon the consummation of the Merger, into Servicesoft
     Common Stock in accordance with the terms of the applicable instruments and
     agreements governing such Servicesoft Preferred Stock.

          (v) Adjustment for Capital Changes. If prior to the Merger, Broadbase
     or Servicesoft (A) recapitalizes either through a split-up of the
     outstanding shares of Broadbase or Servicesoft capital stock into a greater
     number, or through a combination of such outstanding shares into a lesser
     number, (B) reorganizes, reclassifies or otherwise changes such outstanding
     shares into the same or a different number of shares of other classes or
     into securities of another company (other than through a split-up or
     combination of shares provided for in the previous clause), or (C) declares
     a dividend on its outstanding shares payable in shares or securities
     convertible into shares, the calculation of the Conversion Ratio and the
     Escrow Shares (as defined in Section 2.2(b)) will be adjusted appropriately
     so as to maintain the proportionate interests of the Servicesoft
     Stockholders and the holders of shares of Broadbase capital stock at the
     time of such recapitalization.

          (vi) Fractional Shares. No fractional shares of Broadbase common stock
     will be issued in connection with the Merger. However, in lieu thereof,
     each Servicesoft Stockholder who would otherwise be entitled to receive a
     fraction of a share of Broadbase common stock (excluding with respect to
     Servicesoft Options) will receive from Broadbase, together with the
     Exchange Shares to be delivered to such Servicesoft Stockholder, pursuant
     to Section 8.2(a)(i), an amount of cash equal to the product obtained by
     multiplying (A) the closing price of a share of Broadbase common stock on
     the Nasdaq National Market on the last trading day before the Effective
     Time by (B) the fraction of a share of Broadbase common stock that such
     holder would otherwise have been entitled to receive.

          (b) Effects of the Merger. At the Effective Time: (i) Newco will merge
     with and into Servicesoft, Servicesoft will be the Surviving Corporation
     pursuant to the terms of the Certificate of Merger and the separate
     existence of Newco will thereupon cease; (ii) each share of Servicesoft
     Common Stock and each Servicesoft Option outstanding immediately prior to
     the Effective Time will be converted as provided in this Section 2.1,
     subject to the escrow provisions of Section 2.2; (iii) each share of common
     stock of Newco that is issued and outstanding immediately prior to the
     Effective Time will, by virtue of the Merger and without further action on
     the part of the sole stockholder of Newco, be converted into and become one
     share of common stock of the Surviving Corporation (and the shares of
     Surviving Corporation into which the shares of Newco common stock are so
     converted shall be the only shares of Servicesoft Common Stock that are
     issued and outstanding immediately after the Effective Time); (iv) the
     certificate of incorporation and bylaws of Servicesoft shall be amended and
     restated to contain provisions in substantially the form set forth in the
     certificate of incorporation and bylaws of Newco; (v) the sole director and
     officers of Newco immediately prior to the Effective Time will become the
     sole director and officers of the Surviving Corporation; (vi) each

                                       A-5
<PAGE>   222

     share of Servicesoft's capital stock held by Servicesoft or owned by Newco,
     Broadbase or any direct or indirect wholly-owned subsidiary of Servicesoft
     or of Broadbase immediately prior to the Effective Time shall be canceled
     and extinguished without any conversion thereof; and (vii) the Merger will,
     from and after the Effective Time, have all of the effects provided by
     applicable law.

     2.2  Escrow

     (a) Escrow Agent. State Street Bank and Trust Company of California, N.A.,
or such other escrow agent selected by Broadbase prior to the Closing and
reasonably acceptable to Servicesoft (the "Escrow Agent") shall hold, release
and perform other tasks related to the Escrow Shares pursuant to the provisions
of the Escrow Agreement.

     (b) Escrow Shares. Broadbase shall withhold from the number of Exchange
Shares to be issued to each Servicesoft Stockholder pursuant to Section
2.1(a)(i), upon surrender of such Stockholder's Servicesoft Certificates, that
number of Exchange Shares equal to ten percent (10%) of the Exchange Shares to
be issued to such Servicesoft Stockholder pursuant to Section 2.1(a)(i), rounded
to the nearest whole share (collectively, the "Escrow Shares"). As soon as
practicable after the Effective Time, and in accordance with the provisions of
the Escrow Agreement, Broadbase will deposit with the Escrow Agent certificates
representing the Escrow Shares, issued in the name of each Servicesoft
Stockholder according to the number of Escrow Shares withheld from such
Servicesoft Stockholder hereunder, together with related stock transfer powers.

     For the purposes of this Agreement and the Escrow Agreement, Escrow Shares
will be deemed to have a per share value equal to the average of the closing
prices of Broadbase Common Stock for the 10 trading days ending 2 trading days
prior to the Closing (provided that such price shall be subject to adjustment to
reflect any capital change in Broadbase of the type referred to in Section
2.1(a)(v), whether occurring at or after the Effective Time, and Broadbase shall
promptly provide the Escrow Agent with written notice of such capital change) as
provided in the Escrow Agreement.

     (c) Escrow Period. The Escrow Agent will hold the Escrow Shares and any
dividends and distributions on the Escrow Shares as collateral for Servicesoft's
indemnification obligations, and shall release such Escrow Shares and any
dividends or distributions thereon in accordance with the terms of the Escrow
Agreement and Article 12.

     (d) Consent to Escrow Agreement. In the event that the Merger is approved
by the Servicesoft Stockholders as provided herein, the Servicesoft Stockholders
shall, without any further act of any Servicesoft Stockholder, be deemed to have
consented to and approved (i) the use of the Escrow Shares as collateral for
Servicesoft's indemnification obligations under Article 12 in the manner set
forth in the Escrow Agreement, (ii) the appointment of Mark Skapinker as the
representative of the Servicesoft Stockholders (the "Representative") under the
Escrow Agreement and as the attorney-in-fact and agent for and on behalf of each
Servicesoft Stockholder (other than holders of Dissenting Shares), and the
taking by the Representative of any and all actions and the making of any
decisions required or permitted to be taken by him under the Escrow Agreement
(including, without limitation, exercising the power to: authorize delivery to
Broadbase of Escrow Shares in satisfaction of claims by Broadbase; agreeing to,
negotiating, entering into settlements and compromises of and demanding
arbitration and complying with orders of courts and awards of arbitrators with
respect to such claims; resolving any claim made pursuant to Section 12.2; and
taking all actions necessary in the judgment of the Representative for the
accomplishment of the foregoing) and (iii) to all of the other terms, conditions
and limitations in the Escrow Agreement.

     2.3  Securities Law Compliance.

     (a) Issuance of Exchange Shares in Exchange for Servicesoft Common
Stock. The offer, sale and issuance of the Exchange Shares to be issued in the
Merger shall be registered under the Securities Act on Form S-4 promulgated
thereunder. As promptly as practicable after the date of this Agreement,
Broadbase and Servicesoft shall prepare and file with the SEC a Form S-4
registration statement (the "Form S-4") together with the prospectus/proxy
statement included therein (the "Prospectus/Proxy

                                       A-6
<PAGE>   223

Statement") and any other documents required by the Securities Act or the
Exchange Act in connection with the Merger. Each of Broadbase and Servicesoft
shall use all reasonable efforts to have the Form S-4 declared effective under
the Securities Act as promptly as practicable after such filing. Broadbase shall
also take any action required to be taken under any applicable state securities
or "Blue Sky" laws in connection with the issuance of the Exchange Shares in the
Merger. Servicesoft shall furnish to Broadbase all information concerning
Servicesoft and the Servicesoft Stockholders as may be reasonably requested in
connection with any action contemplated by this Section 2.3(a). Broadbase shall
furnish to Servicesoft all information concerning Broadbase as may be reasonably
requested in connection with any action contemplated by this Section 2.3(a).

     (b) Issuance of Exchange Shares Pursuant to Exercises of Exchange
Options. Broadbase shall cause the Exchange Shares that are issuable upon
exercise of the Broadbase Options to be registered under the Securities Act on
Form S-8 or any other applicable form within 15 days after the Closing Date.
Broadbase will use reasonable efforts to maintain the effectiveness of such
registration statement (and maintain the current status of the prospectus or
prospectuses incorporated therein) so long as the Broadbase Options (or shares
issued upon exercise thereof) remain outstanding.

     (c) Resale of Exchange Shares. Holders of Exchange Shares will be wholly
responsible for compliance with all federal and state securities laws regarding
the sale, transfer or other disposition of such shares.

     2.4  Tax and Accounting Aspects of the Merger.

     (a) Tax Free Reorganization. The parties intend to adopt this Agreement as
a tax-free plan of reorganization and to consummate the Merger in accordance
with the provisions of Section 368(a)(1)(A) and Section 368(a)(2)(E) 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

promptly with any requests to it from the Federal Trade Commission or United
States Department of Justice for additional information.

     2.6  Further Assurances. Servicesoft agrees that if, at any time before or
after the Effective Time, Broadbase considers or is advised that any further
deeds, assignments or assurances are reasonably deemed necessary or desirable by
Broadbase to vest, perfect or confirm in Broadbase title to any property or
rights of Servicesoft or the Surviving Corporation as provided herein,
Broadbase, the Surviving Corporation and their respective proper officers and
directors are hereby authorized by Servicesoft to execute and deliver all such

to such property or rights in Broadbase and otherwise to carry out the purpose
of this Agreement, in the name of Servicesoft or otherwise. The officers and

this Agreement.

     3. Additional Agreements

regulatory rules provided that such press releases or other disclosures
regarding the Merger shall not be made without the prior consent and approval of
both parties with respect to the content of such releases and disclosures and
with respect to the decision to release such press releases or disclosures.

                                       A-7
<PAGE>   224

precautions to prevent any trading in the securities of Broadbase by officers,
directors, employees and agents of Servicesoft, having knowledge of any material
information regarding Broadbase provided hereunder, including, without
limitation, the existence of the transactions contemplated by this Agreement
until the information in question has been publicly disclosed.

     3.2  Fees and Expenses. Each party will bear its respective expenses and
fees of its own accountants, attorneys, investment bankers and other
professionals incurred with respect to this Agreement and the transactions
contemplated hereby. Any such fees and expenses of Servicesoft in excess of
$500,000, excluding the fees and expenses of investment bankers, ("Excess
Expenses"), shall be paid by the Servicesoft Stockholders. All other fees and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses whether

Servicesoft shall share equally all fees and expenses, other than attorneys' and
accountants fees and expenses, incurred in relation to the printing and filing
with the SEC of the Form S-4 (including financial statements and exhibits) and
any amendments or supplements thereto) and the Proxy Statement/Prospectus

Stockholder's risk of ownership or investment in, or make any offer or enter
into any agreement relating to any of the foregoing with respect to any shares
of the capital stock of Broadbase (including, without limitation, the Exchange
Shares and any additional shares of capital stock of Broadbase acquired by such
Servicesoft Stockholder, whether upon exercise of a stock option or otherwise),
or any option or other right to purchase any shares of capital stock of
Broadbase, during the period beginning on the date of this Agreement and ending
on the date that is 90 days after the Closing Date. Notwithstanding the
foregoing, in the event Broadbase enters into an agreement with respect to a
Broadbase Acquisition (as such term is defined in Section 7.2(g)), the
restrictions described in the previous sentence shall terminate on the date that
is two days after the record date for a Broadbase stockholders' meeting to
consider such Broadbase Acquisition, except with respect to a Servicesoft
Affiliate who is at such time an Affiliate (as defined in the Securities Act) of
Broadbase. Any such Servicesoft Affiliate shall be subject to any and all
restrictions on transfer that are applicable to all officers, directors and
other affiliates of Broadbase, whether by contract or pursuant to Broadbase
policy.

     3.4  Integration Matters. Servicesoft and Broadbase will cooperate in good
faith to identify and, to the extent practicable, to resolve matters regarding
the orderly integration of their respective operations.

     4. Representations and Warranties of Servicesoft

     Except as set forth in the Servicesoft Disclosure Letter delivered to
Broadbase and Newco herewith, (which, subject to Section 13.14, shall
specifically refer to the Sections of this Agreement to which the specific Items
of the Servicesoft Disclosure Letter therein constitute an exception),
Servicesoft hereby represents and warrants to Broadbase as follows:

          4.1  Organization and Good Standing. Servicesoft and each Subsidiary
     (as defined in Section 4.2) is a corporation duly organized, validly
     existing and, where applicable, in good standing under the laws of the
     jurisdiction of its incorporation and has all requisite corporate power and
     authority, and all requisite qualifications to do business as a foreign
     corporation, to conduct its business in the manner in which its business is
     currently being conducted, except where the failure to be so organized,
     existing or in good standing or to have such power, authority or
     qualifications would not, individually or in the aggregate, reasonably be
     expected to have a Material Adverse Effect on Servicesoft. Except as set
     forth on Item 4.1 of the Servicesoft Disclosure Letter, Servicesoft has
     delivered or made available to Broadbase a true and correct copy of its
     certificate of incorporation and bylaws and similar governing instruments
     of each Subsidiary, each as amended to date (collectively, the "Servicesoft
     Charter Documents"), and each such instrument is in full force and effect.
     Neither Servicesoft nor any Subsidiary is in violation of any of the
     provisions of the Servicesoft Charter

                                       A-8
<PAGE>   225

     Documents. Servicesoft has delivered or made available to Broadbase all
     proposed or considered amendments to the Servicesoft Charter Documents.

          4.2  Subsidiaries and Guarantees. Except for the subsidiaries of
     Servicesoft listed in Item 4.2 of the Servicesoft Disclosure Letter
     (collectively the "Subsidiaries" and each a "Subsidiary"), Servicesoft does
     not have any subsidiaries or any interest, direct or indirect, in any
     corporation, partnership, joint venture or other business entity. Neither
     Servicesoft nor any Subsidiary has agreed or is obligated to make, or is
     bound by any written agreement, contract, subcontract, lease, letter of
     intent, instrument, note, option, warranty, purchase order, license,
     sublicense, insurance policy, or benefit plan as in effect as of the date
     hereof pursuant to which it is required to make any future investment in or
     capital contribution to any other entity. Neither Servicesoft, nor any
     Subsidiary, is a general partner of any general partnership, limited
     partnership or other entity. Item 4.2 of the Servicesoft Disclosure Letter
     indicates the jurisdiction of organization of each entity listed therein
     and Servicesoft's direct or indirect equity interest therein.

          4.3  Capitalization.

          (a) Authorized/Outstanding Capital Stock. As of the close of business

     liability for dividends accrued but unpaid; or (vi) condition or
     circumstance, to Servicesoft's knowledge, that likely would directly or
     indirectly give rise to or provide a basis for the assertion of a claim by
     any person to the effect that such person is entitled to acquire or receive
     any shares of capital stock or other securities of Servicesoft, including
     but not limited to promises to issue or grant securities of Servicesoft or
     to recommend to Servicesoft's board of directors to issue or grant
     securities of Servicesoft.

     authority to: (i) carry on its business as now conducted; (ii) own, operate

     are proposed to be owned, used and leased; (iii) perform its obligations
     under all Servicesoft Contracts, and (iv) enter into and perform its

     Servicesoft's stockholders (the "Servicesoft Stockholder Approval") and the

     of Servicesoft Common Stock, Series H Preferred Stock, Series I Preferred
     Stock, Series J Preferred Stock, Series X Special Preferred Stock and

     Document. Neither Servicesoft, nor any Subsidiary is required to file any
     forms, reports or other documents with the SEC.

     No. 333-30476), as amended by Amendment No. 4 thereto, filed with the SEC
     on August 25, 2000 (the "Servicesoft S-1") (such financial statements, the

     the respective dates thereof and the consolidated results of Servicesoft's
     and its Subsidiaries' operations and cash flows for the periods indicated,
     except that the unaudited interim financial statements may not contain
     footnotes and were or are subject to normal and recurring year-end
     adjustments. Except as set forth in Item 4.7 of the Servicesoft Disclosure
     Letter, since Servicesoft's June 30, 2000 balance sheet (the "Servicesoft
     Balance Sheet", with June 30, 2000 hereinafter referred to as the
     "Servicesoft Balance Sheet Date") contained in the Servicesoft S-1, neither
     Servicesoft nor any Subsidiary has any liabilities (absolute, accrued,
     contingent or otherwise) which are, individually or in the aggregate,
     material to the business, results of operations or financial condition of
     Servicesoft and the Subsidiaries taken as a whole, except for (i)

     adversely to Servicesoft or any Subsidiary, may reasonably be expected to
     have a Material Adverse Effect on Servicesoft. There is no judgment,
     decree, injunction or ruling

                                      A-12

     of an administrative agency or arbitrator outstanding against Servicesoft
     or any Subsidiary, except as may reasonably be expected to have a Material
     Adverse Effect on Servicesoft or any Subsidiary of Servicesoft. To the
     knowledge of Servicesoft, there is no basis for any person, firm,
     corporation or entity to assert a claim against Servicesoft or any

     between Servicesoft and any Servicesoft securities holder or former
     Servicesoft securities holder in such holder's capacity as such. As of the
     date hereof, there is no action, suit, proceeding, claim, arbitration or
     investigation pending as to which Servicesoft has received notice of
     assertion against Servicesoft, which in any manner challenges or seeks to
     prevent, enjoin, alter or materially delay any of the transactions
     contemplated by this Agreement.

     and encumbrances of any kind, except: (i) Permitted Liens and (ii)
     imperfections in title which do not, individually or in the aggregate,
     prevent such assets from being used for the purpose for which they are
     currently being used or otherwise materially impair the operations of
     Servicesoft.

             (xii) been the subject of any pending or, to Servicesoft's
        knowledge, threatened labor dispute or claim of unfair labor practices;

        any of the foregoing (other than as disclosed in Item 4.11(b)).

          4.12  Intellectual Property.

     Rights" shall mean all worldwide industrial and intellectual property
     rights, including, without limitation, patents, patent applications, patent
     rights, trademarks, trademark applications, trade names, service marks,
     service mark applications, URLs, copyright, copyright applications, mask
     work rights, moral rights, franchises, licenses, inventories, know-how,

     and media constituting, describing or relating to the above, including,
     without limitation, manuals, memoranda and records.

          (b) Ownership of Intellectual Property. Servicesoft and each
     Subsidiary of Servicesoft owns all right, title and interest in, or has
     license (sufficient for the conduct of its business as presently
     conducted), to all Intellectual Property Rights used in or reasonably
     necessary to the conduct of its business as presently conducted (with such
     Intellectual Property Rights being hereinafter collectively referred to as
     the "Servicesoft IP Rights"). Except as set forth in Item 4.12(b)(i) of the
     Servicesoft Disclosure Letter, Servicesoft has the unrestricted, worldwide
     right to design, develop, use, reproduce, manufacture, sell, license and
     distribute all of its products and services (such products and services
     being set forth in Item 4.12(b)(ii) of the Servicesoft Disclosure Letter
     and hereinafter collectively referred to as the "Servicesoft Products and
     Services") as such Servicesoft Products and Services are currently being
     designed, developed, used, reproduced, manufactured, sold, licensed and
     distributed, and the right to use all of its customer and supplier lists.
     Except as set forth in Item 4.12(b)(iii), neither Servicesoft nor any
     Subsidiary has granted any reseller, distributor, sales representative,
     original equipment manufacturer, value added reseller or other third party
     any right to reproduce, manufacture, sell, license or distribute any of its
     products or services in any market segment or geographic location. Set
     forth in Item 4.12(b)(iv) is a true and complete list of all copyright,
     mask work and trademark registrations and applications and all patents and
     patent applications for Servicesoft IP Rights owned by Servicesoft or its
     Subsidiaries. Except for licensed materials pursuant to agreements set
     forth in Item 4.12(b)(i) of the Servicesoft Disclosure Letter and except
     for widely available commercial software licensed by Servicesoft from third
     parties on standard commercial terms, all Servicesoft IP Rights are owned
     by Servicesoft or its U.S. or Canadian Subsidiaries (or, with respect to
     customer lists of other Subsidiaries or consulting work product created by
     other Subsidiaries, such other Subsidiaries). Except as set forth in Item
     4.12(b)(i) and Item 4.14 of the Servicesoft Disclosure Letter, Servicesoft
     has not transferred ownership of or granted any third parties any rights in
     or with respect to any Servicesoft IP Rights, other than non-exclusive
     licenses granted in the ordinary course of business. Servicesoft is not
     aware of any loss, cancellation, termination or expiration of any such
     registration or patent except as set forth in Item 4.12(b)(v) of the
     Servicesoft Disclosure Letter. The execution, delivery and performance of
     this Agreement and the consummation of the transactions contemplated hereby
     will not constitute a material breach of any instrument or agreement
     governing any Servicesoft IP Right, will not cause forfeiture or
     termination or give rise to a right of forfeiture or termination of any
     Servicesoft IP Right or materially impair the right of Servicesoft to use,
     sell or license any Servicesoft IP Right or portion thereof.

          (c) No Violation of Rights of Others. The business of Servicesoft and
     each Subsidiary of Servicesoft and the design, development, use,
     manufacture, sale, license or provision of any Servicesoft Product and
     Service does not, and will not as a result of the Merger, cause Servicesoft
     or any Subsidiary of Servicesoft to infringe or violate any of the
     Intellectual Property Rights of any other person nor will any claim of such
     infringement or violation after the Effective Date arise from facts prior
     to the Effective Date; provided that with respect to infringement of
     patents, the representation in the preceding clause of this sentence only
     relates to patents known to Servicesoft. Except as set forth in Item
     4.12(c) of the Servicesoft Disclosure Letter, neither Servicesoft nor any
     Subsidiary has received any written or oral claim or notice of infringement
     or potential infringement of the Intellectual Property Rights of any other
     person. To the knowledge of Servicesoft, neither Servicesoft nor any
     Subsidiary is using any confidential information or trade secrets of third
     party, including, but not limited to, any past or present employees or
     their respective past employers. There are no royalties, honoraria, fees or
     other payments payable by Servicesoft or any Subsidiary of Servicesoft to
     any third party under any written or oral contract or understanding or
     otherwise by reason of the ownership, use, license, sale, or disposition of
     any Intellectual Property that is or was Servicesoft IP Rights (other than
     as set forth in Item 4.12(c) of the Servicesoft Disclosure Letter).

          (d) Protection of Rights. Servicesoft has taken commercially
     reasonable and practicable steps designed to safeguard and maintain the
     secrecy and confidentiality of, and its proprietary rights in, all

                                      A-17
<PAGE>   234

     Servicesoft IP Rights. To the knowledge of Servicesoft, there is no
     material unauthorized use, infringement or misappropriation of any
     Servicesoft IP Rights by any third party, including, to the knowledge of
     Servicesoft, any Servicesoft employee or Subsidiary employee. All current
     Servicesoft and Subsidiary officers, employees and consultants (other than
     employees and consultants who are not and have not been involved in
     developing Servicesoft IP Rights or providing services to customers and who
     have no managerial responsibilities) have executed and delivered to
     Servicesoft an agreement regarding the protection of proprietary
     information and the assignment to Servicesoft of all Intellectual Property
     Rights arising from the services performed for Servicesoft or any
     Subsidiary by such persons, and Servicesoft made available or has delivered
     to Broadbase or its counsel copies of all such agreements.

          (e) Conformity of Products and Services. All software developed by
     Servicesoft or any Subsidiary and licensed by Servicesoft or any Subsidiary
     to customers and all other products manufactured, sold, licensed, leased or
     delivered by Servicesoft or any Subsidiary to customers and all services
     provided by Servicesoft or any Subsidiary to customers on or prior to the
     Closing Date conform in all material respects (to the extent required in
     Contracts with such customers) to applicable contractual commitments,
     express and implied warranties, product specifications and product
     documentation and to any representations provided to customers and
     Servicesoft has no material liability or obligation (and, to Servicesoft's
     knowledge, there is no legitimate basis for any present or future action,
     suit, proceeding, hearing, investigation, charge, complaint, claim or
     demand against Servicesoft giving rise to any material liability or
     obligation) for replacement or repair thereof or other damages in
     connection therewith in excess of any reserves therefor set forth on the
     Balance Sheet. Servicesoft and its Subsidiaries have no obligations with
     respect to any product or service to deliver any new or additional
     functionalities, versions, ports or products, or to perform any additional
     services, except for (i) maintenance and support obligations incurred in
     the ordinary course of business and consistent with past practices, made
     available on substantially similar terms to all customers who have obtained
     substantially similar products or services, and (ii) future consulting
     service or license obligations incurred in the ordinary course of business
     with respect to prior consulting engagements, and not resulting from the
     failure of any products licensed or sold or services rendered by
     Servicesoft or its Subsidiaries to comply in a material respect with any
     applicable commitments, specifications or warranties, and (iii) obligations
     which are reflected in reserves on the Balance Sheet identified to the
     future obligation(s) in question. Servicesoft and its Subsidiaries have
     good commercial working relationships with their customers and suppliers.
     Servicesoft and each Subsidiary of Servicesoft has taken such actions as
     are necessary or appropriate to document the software and its operations
     found in the Servicesoft Products and Services and any software used in the
     development, compilation, maintenance and support of the Servicesoft
     Products and Services, such that the materials comprising such software,
     including the source code and documentation, have been written in a clear
     and professional manner so that they may be understood, modified and
     maintained in an efficient manner by reasonably competent programmers.

          4.13  Compliance with Laws. Servicesoft and each Subsidiary is and
     will be at the Closing Date in compliance, in all respects material to
     Servicesoft, with all applicable laws, ordinances, regulations and rules,
     and all orders, writs, injunctions, awards, judgments and decrees,
     applicable to Servicesoft or any Subsidiary, or to the assets, properties
     and business of Servicesoft or any Subsidiary, including, without
     limitation:

             (a) all applicable federal and state securities laws and
        regulations;

             (b) all applicable federal, state and local laws, ordinances and
        regulations, and all orders, writs, injunctions, awards, judgments and
        decrees, pertaining to (i) the sale, licensing, leasing, ownership or
        management of Servicesoft's or any Subsidiary's owned, leased or
        licensed real or personal property, products or technical data, (ii)
        employment or employment practices, terms and conditions of employment,
        or wages and hours or (iii) safety, health, fire prevention,
        environmental protection (including toxic waste disposal and related
        matters described in Section 4.16), building standards, zoning or other
        similar matters;

                                      A-18
<PAGE>   235

             (c) the Export Administration Act and regulations promulgated
        thereunder or other laws, regulations, rules, orders, writs,
        injunctions, judgments or decrees applicable to the export or re-export
        of controlled commodities or technical data;

             (d) the Immigration Reform and Control Act; and

             (e) all governmental and nongovernmental regulations related to the
        operation and use of the Internet.

          Servicesoft and each Subsidiary has received all material permits and
     approvals from, and has made all material filings with, third parties,
     including government agencies and authorities, that are necessary to the
     conduct of its business as presently conducted.

          4.14  Agreements and Commitments. Except as set forth in Item 4.14 of
     the Servicesoft Disclosure Letter and delivered or made available by
     Servicesoft to Broadbase herewith, or as listed in Item 4.12 or Item 4.15
     as required by Section 4.12 or Section 4.15, as the case may be, neither

        or any advance to any employee of Servicesoft or of any Subsidiary
        incurred or made in the ordinary course of business, and except as
        disclosed in the Servicesoft Financial Statements;

             (l) Any Contract containing covenants purporting to limit

          All agreements, obligations and commitments listed in Item 4.12, Item
     .14, or Item 4.15, as required by Section 4.12, this Section 4.14, or
     Section 4.15, as the case may be, are valid and in full force and effect,
     and except as expressly noted, a true and complete copy of each has been
     delivered or made available to Broadbase. Except as noted in Item 4.14,
     neither Servicesoft nor, to the knowledge of Servicesoft, any other party
     is in material breach of or default under any material term of any such
     agreement, obligation or commitment. Neither Servicesoft nor any Subsidiary
     has any liability for renegotiation of government Contracts or
     sub-Contracts which are material to Servicesoft.

          4.15  Employees.

          (a) General Compliance. Servicesoft and each of the Subsidiaries is in
     compliance in all material respects with all applicable laws relating to
     employment, employment practices, wages, hours, and terms and conditions of
     employment, including, but not limited to, employee compensation matters,
     and has correctly classified employees as exempt employees and non-exempt
     employees under the Fair Labor Standards Act. Except as set forth in Item
     4.15(a) of the Servicesoft Disclosure Letter, neither Servicesoft nor any
     Subsidiary has employment or consulting Contracts currently in effect that
     are not terminable at will (other than agreements with the sole purpose of
     providing for the confidentiality of proprietary information or assignment
     of inventions). All independent contractors have been properly classified
     as independent contractors for the purposes of federal and applicable state
     Tax laws, laws applicable to employee benefits and other applicable laws.
     All Servicesoft or Subsidiary employees are legally permitted to be
     employed by Servicesoft or the Subsidiary in the United States of America.
     Servicesoft will have no liability to any employee or to any organization
     or any other entity as a result of the termination of any employee leasing
     arrangement.

          (b) Good Labor Relations. Servicesoft and each of the Subsidiaries:
     (i) has never been and is not now subject to a union organizing effort;
     (ii) is not subject to any collective bargaining agreement with respect to
     any of its employees; (iii) is not subject to any other Contract with any
     trade or labor union, employees' association or similar organization; and
     (iv) has no current labor disputes and has had no material labor disputes
     or claims of unfair labor practices since December 31, 1999. Servicesoft
     and the Subsidiaries have good labor relations, and have no knowledge of
     any facts

                                      A-20
<PAGE>   237

     indicating that the consummation of the Merger or any of the other
     transactions contemplated hereby will have a Material Adverse Effect on
     such labor relations. Between January 1, 2000 and the date of this
     Agreement, to Servicesoft's knowledge, no executive officer of Servicesoft
     or any of its Subsidiaries, or material number of other employees of
     Servicesoft or any of its Subsidiaries, has given notice that such employee
     intends to terminate his or her employment with Servicesoft or any such
     Subsidiary. As of the date of this Agreement, Servicesoft has no knowledge
     that any key personnel or other employees intend to leave its or a
     Subsidiary's employment. There are no controversies pending or, to
     Servicesoft's knowledge, threatened, between Servicesoft or any Subsidiary
     and any of their employees that would be reasonably likely to result in
     Servicesoft incurring any material liability.

          (c) Employee Plans. Item 4.15(c) of the Servicesoft Disclosure Letter
     identifies: (i) each "employee benefit plan", as defined in Section 3(3) of
     the Employee Retirement Income Security Act of 1974, as amended ("ERISA");
     and (ii) all other written or formal plans or Contracts involving direct or
     indirect compensation or benefits (including any employment Contracts
     entered into between Servicesoft or any Subsidiary and any employee of
     Servicesoft or any Subsidiary, but excluding workers' compensation,
     unemployment compensation and other government-mandated programs) currently
     or previously maintained, contributed to or entered into by Servicesoft or
     any Subsidiary under which Servicesoft or any Subsidiary or any ERISA
     Affiliate (as defined below) has any present or future Liability
     (collectively, the "Servicesoft Employee Plans"). For purposes of this
     Section 4.15, "ERISA Affiliate" shall mean any entity which is a member of:
     (i) a "controlled group of corporations", as defined in Section 414(b) of
     the Code; (ii) a group of entities under "common control", as defined in
     Section 414(c) of the Code; or (iii) an "affiliated service group", as
     defined in Section 414(m) of the Code, or treasury regulations promulgated
     under Section 414(o) of the Code, any of which includes Servicesoft or any
     Subsidiary. Copies of all Servicesoft Employee Plans (and, if applicable,
     related trust agreements) and all related documents, amendments and written
     interpretations (including summary plan descriptions) thereto have been
     made available to Broadbase or its counsel, together with the two most
     recent annual reports (Form 5500, including, if applicable, Schedule B
     thereto) prepared in connection with any such Servicesoft Employee Plan. No
     "prohibited transaction," as defined in Section 406 of ERISA or Section
     4975 of the Code, has occurred with respect to any Servicesoft Employee
     Plan which is covered by Title I of ERISA which would result in a material
     liability to Servicesoft, excluding transactions effected pursuant to a
     statutory or administrative exemption. Nothing done or omitted to be done
     and no transaction or holding of any asset under or in connection with any
     Servicesoft Employee Plan has or will make Servicesoft, any Subsidiary or
     any Servicesoft or Subsidiary officer or director subject to any material
     liability under Title I of ERISA or liability for any material Tax (as
     defined in Section 4.9) or penalty pursuant to Sections 4972, 4975, 4976 or
     4979 of the Code or Section 502 of ERISA. Except as set forth in Item
     4.15(c) of the Servicesoft Disclosure Letter, no Servicesoft Employee Plans
     will be subject to any surrender fees or service fees upon termination
     other than the normal and reasonable administrative fees associated with
     the termination of benefit plans. All contributions due from Servicesoft or
     any Subsidiary with respect to any of the Servicesoft Employee Plans have
     been made as required under such plans and, to the extent applicable,
     ERISA, other than contributions accrued in the ordinary course of business
     consistent with past practice after the Servicesoft Balance Sheet Date as a
     result of operations of Servicesoft and its Subsidiaries after the
     Servicesoft Balance Sheet Date, all of which have been paid or will be paid
     when and as required or, if not required to be made, have been accrued on
     the Servicesoft Financial Statements. Servicesoft and each of the
     Subsidiaries has performed in all material respects all obligations
     required to be performed by it under each Servicesoft Employee Plan, and
     each Servicesoft Employee Plan has been maintained substantially in
     compliance with its terms and with the requirements prescribed by any and
     all statutes, orders, rules and regulations, including, without limitation,
     ERISA and the Code, which are applicable to such Servicesoft Employee
     Plans. All individuals who, pursuant to the terms of any Servicesoft
     Employee Plans, are entitled to participate in any Servicesoft Employee
     Plan, currently are participating in such Servicesoft Employee Plan or have
     been offered an opportunity to do so. No employee of Servicesoft

                                      A-21
<PAGE>   238

     or any of its Subsidiaries, and no person subject to any health plan of
     Servicesoft or any of its Subsidiaries has made medical claims through such
     health plan during the 12 months preceding the date hereof for more than
     $100,000 in the aggregate for which Servicesoft is responsible, or has any
     catastrophic illness.

          (d) Pension Plans. All Servicesoft Employee Plans which individually
     or collectively would constitute an "employee pension benefit plan", as
     defined in Section 3(2) of ERISA (collectively, the "Servicesoft Pension
     Plans"), are identified as such in Item 4.15(d) of the Servicesoft
     Disclosure Letter. Any Servicesoft Pension Plan which is intended to be
     qualified under Section 401(a) of the Code (a "Servicesoft 401(a) Plan") is
     so qualified and has been so qualified during the period from its adoption
     to date, and the trust forming a part is exempt from Tax pursuant to
     Section 501(a) of the Code. No Servicesoft Pension Plan constitutes, or has
     since the enactment of ERISA constituted, a "multiemployer plan," as
     defined in Section 3(37) of ERISA. No Servicesoft Pension Plans are subject
     to Title IV of ERISA. Servicesoft has delivered to Broadbase or its counsel
     a complete and correct copy of the most recent Internal Revenue Service
     determination letter with respect to each Servicesoft 401(a) Plan, if any
     exists.

          (e) Benefit Arrangements. Item 4.15(e) of the Servicesoft Disclosure
     Letter lists each employment, severance (including all post-employment
     Liabilities) or other similar Contract or policy and each Contract
     providing for insurance coverage (including any self-insured arrangements),
     workers' benefits, vacation benefits, severance benefits, disability
     benefits, death benefits, hospitalization benefits, retirement benefits,
     deferred compensation, profit-sharing, bonuses, stock options, stock
     purchase, phantom stock, stock appreciation or other forms of incentive
     compensation or post-retirement insurance, compensation or benefits for
     employees, consultants or directors which: (i) is not a Servicesoft
     Employee Plan; (ii) is entered into, maintained or contributed to by
     Servicesoft or any Subsidiary; and (iii) covers any employee or former
     employee or independent contractor or consultant of Servicesoft or any
     Subsidiary. Such Contracts and policies as are described in this Section
     4.15(e) are herein referred to collectively as the "Servicesoft Benefit
     Arrangements." Each Servicesoft Benefit Arrangement has been maintained in
     substantial compliance with its terms and with the requirements prescribed
     by any and all statutes, orders, rules and regulations which are applicable
     to such Servicesoft Benefit Arrangement. Servicesoft has delivered to
     Broadbase or its counsel a complete and correct copy or description of each
     Servicesoft Benefit Arrangement. All individuals who, pursuant to the terms
     of any Servicesoft Benefit Arrangement, are entitled to participate in any
     such Servicesoft Benefit Arrangement, are currently participating in such
     Servicesoft Benefit Arrangement or have been offered an opportunity to do
     so and have declined.

          (f) Since December 31, 1999, there has been no amendment to, written
     interpretation or announcement (whether or not written) by Servicesoft or
     any Subsidiary relating to, or change in employee participation or coverage
     under, any Servicesoft Employee Plan or Servicesoft Benefit Arrangement
     that would increase materially the expense of maintaining such Servicesoft
     Employee Plan or Servicesoft Benefit Arrangement in the future.

          (g) COBRA Compliance. Servicesoft and each of the Subsidiaries has
     complied in all material respects prior to the date hereof, with the
     continuation coverage requirements of Section 4980B of the Code and the
     Consolidated Omnibus Budget Reconciliation Act of 1985, as amended
     ("COBRA"), Sections 601 through 608 of ERISA, the American Civil
     Disabilities Act of 1990, as amended, and the Family Medical Leave Act of
     1993, as amended, and the regulations thereunder, and no material Tax
     payable on account of Section 4980B of the Code has been incurred with
     respect to any current or former employees (or their beneficiaries) of
     Servicesoft or any Subsidiary.

          (h) No Violation of Contracts. To the knowledge of Servicesoft, no
     Servicesoft or Subsidiary employee or consultant is in violation of any
     term of any employment Contract, patent disclosure agreement,
     non-competition agreement, or any other Contract, or any restrictive
     covenant relating to the right of any such employee to be employed by
     Servicesoft or any Subsidiary, or to use Intellectual Property Rights of
     others.

     or threatened releases of Hazardous Materials on, from or under any of such
     properties or facilities that may have occurred prior to Servicesoft or a
     Subsidiary having taken possession of any of such properties or facilities.

          4.17  Certain Transactions and Agreements. To Servicesoft's knowledge,
     no person who is an officer or director of Servicesoft or any Subsidiary,
     or a member of any such officer's or director's immediate family:

             (a) has any direct or indirect ownership interest in or any
        employment or consulting agreement with any firm or corporation that
        competes with Servicesoft or any Subsidiary, or with Broadbase (except
        with respect to any interest in less than 2% of the outstanding voting
        shares of any corporation whose stock is publicly traded);

             (b) is directly or indirectly interested in any Contract with
        Servicesoft or any Subsidiary, including, but not limited to, any loan
        arrangements, except for compensation for services as an officer (listed
        in Item 4.17 of the Servicesoft Disclosure Letter), director or employee
        of Servicesoft and except for the normal rights of a stockholder or
        optionholder.

             (c) has any interest in any (i) Servicesoft IP Rights or (ii)
        property (other than Servicesoft IP Rights) used in the business of
        Servicesoft or any Subsidiary whether such property is real or personal,
        tangible or intangible.

          To Servicesoft's knowledge, no Servicesoft or Subsidiary officer or
     director, or any "affiliate" or "associate" (as those terms are defined in
     Rule 405 promulgated under the Securities Act) of any such person has had,
     either directly or indirectly, a material interest in: (i) any entity which
     purchases from or sells, licenses or furnishes to Servicesoft or any
     Subsidiary any goods, property, technology or intellectual or other
     property rights or services, or (ii) any Contract to which Servicesoft or
     any Subsidiary is a party or by which it may be bound or affected other
     than with respect to arms-length transactions.

          4.18  Accounts Receivable. The receivables shown on the balance sheet
     of Servicesoft on the Servicesoft Balance Sheet Date arose in the ordinary
     course of business consistent with past practice and have been collected
     or, as of the date of this Agreement, are collectible in the book amounts
     thereof, less an amount not in excess of the allowance for doubtful
     accounts provided for in the balance sheet of Servicesoft on the
     Servicesoft Balance Sheet Date. Allowances for doubtful accounts and
     warranty returns have been prepared in accordance with GAAP consistently
     applied and in accordance with the past practices of Servicesoft and its
     Subsidiaries. The receivables of Servicesoft and its Subsidiaries arising
     after the Servicesoft Balance Sheet Date and prior to the Closing Date
     arose or will arise in the ordinary course of business consistent with past
     practice and have been collected or are, as of the date of this Agreement,
     collectible in the book amounts thereof, less allowances for doubtful
     accounts and warranty returns determined in accordance with the past
     practices of Servicesoft and its Subsidiaries. None of Servicesoft's
     receivables is subject to any material claim of offset, recoupment, setoff
     or counter-claim and it has no knowledge of any specific facts or
     circumstances (whether asserted or unasserted) that could give rise to any
     such claim. No material amount of receivables are contingent upon the
     performance by Servicesoft or any of its

                                      A-24
<PAGE>   241

     Subsidiaries of any obligation or contract other than normal warranty
     repair and replacement and other than products' progress bills in the
     ordinary course of business consistent with past practice. No person has
     any lien on any of such receivables (except Permitted Liens) and no
     agreement for deduction or discount has been made with respect to any of
     such receivables. Item 4.18 of the Servicesoft Disclosure Letter sets forth
     as of August 31, 2000, or such other date as specified therein, an aging of
     accounts receivable of Servicesoft and its Subsidiaries in the aggregate
     and by customer. There are no accounts receivable which are subject to
     asserted warranty claims known to Servicesoft made within the last year,
     including the type and amounts of such claims.

          4.19  Board of Directors, Officers and Key Personnel. Item 4.19 of the
     Servicesoft Disclosure Letter accurately sets forth, as of the date of this
     Agreement: (a) the name and title of each of Servicesoft's officers and its
     Subsidiaries' officers; (b) the name and title of supervisory,
     developmental or other key personnel of Servicesoft and its Subsidiaries;
     and (c) the name and address of each member of Servicesoft's board of
     directors, except as otherwise indicated thereon, and its Subsidiaries'
     boards of directors.

          4.20  Insurance. Servicesoft and each Subsidiary maintains, and at all
     times since its inception has maintained, fire and casualty, workers
     compensation, general liability, business interruption and product
     liability insurance (which policies are listed in Item 4.20 of the
     Servicesoft Disclosure Letter) which it believes to be reasonably prudent
     for similarly sized and similarly situated businesses. Item 4.20 sets forth
     all material claims made under insurance policies since December 31, 1997
     and the premiums that apply with respect to such insurance policies as of
     the date of this Agreement.

          4.21  Voting Arrangements. Except for the Voting Agreements, or as set
     forth in Item 4.5 of the Servicesoft Disclosure Letter, there are no
     outstanding stockholder agreements, voting trusts, proxies or other
     Contracts to which Servicesoft or, to Servicesoft's knowledge, to which any
     other person or entity is a party, relating to the voting of any shares of
     Servicesoft's capital stock.

          4.22  Ownership of Shares of Broadbase Capital Stock. Except as set
     forth in Item 4.22 of the Servicesoft Disclosure Letter, as of the date
     hereof, neither Servicesoft nor any Subsidiary nor, to Servicesoft's
     knowledge, any of Servicesoft's affiliates or associates (as such terms are
     defined under the Exchange Act of 1934): (a) beneficially owns, directly or
     indirectly; or (b) is party to any Contract for the purpose of acquiring,
     holding, voting or disposing of, in each case, shares of Broadbase capital
     stock (except for shares of Broadbase capital stock in the aggregate
     representing less than 1% of the outstanding shares of Broadbase capital
     stock).

          4.23  Information Supplied. None of the information supplied or to be
     supplied by Servicesoft for inclusion in the Form S-4 and the
     Prospectus/Proxy Statement (both as defined in Section 2.3(a)), at the date
     such information is supplied, at the time of the meeting of the
     stockholders of Broadbase to approve the Merger, and at the time of the
     meeting, or the date of the written consent, of the Servicesoft
     Stockholders to approve the Merger, contains or will contain any untrue
     statement of a material fact or omits or will omit to state any material
     fact required to be stated therein or necessary in order to make the
     statements therein, in light of the circumstances under which they are
     made, not misleading, or will, in the case of the Form S-4, at the time the
     Form S-4 becomes effective under the Securities Act, contains any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements therein, in light of
     the circumstances under which they are made, not misleading.

          4.24  Accuracy of Disclosure. The representations and warranties
     contained in this Agreement, taken together with the Servicesoft Disclosure
     Letter and any exhibits, schedules, certificates and documents to be
     delivered by Servicesoft to Broadbase pursuant to this Agreement, do not
     contain any untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements contained herein and
     therein, in light of the circumstances under which such statements were
     made, not misleading.

     5. Representations and Warranties of Broadbase and Newco

     Except as set forth in the Broadbase Disclosure Letter, (which, subject to
Section 13.14, shall specifically refer to the Sections of this Agreement to
which the specific Items of the Servicesoft Disclosure Letter therein constitute
an exception), each of Broadbase and Newco, where applicable, hereby represents
and warrants to Servicesoft as follows:

          5.1  Organization and Good Standing. Each of Broadbase and Newco is a
     corporation duly organized, validly existing and, where applicable, in good
     standing under the laws of the jurisdiction of its incorporation and has
     all requisite corporate power and authority, and all requisite
     qualifications to do business as a foreign corporation, to conduct its
     business in the manner in which its business is currently being conducted,
     except where the failure to be so organized, existing or in good standing
     or to have such power, authority or qualifications would not, individually
     or in the aggregate, reasonably be expected to have a Material Adverse
     Effect on Broadbase. Broadbase has delivered or made available to
     Servicesoft a true and correct copy of its and Newco's certificate of
     incorporation and bylaws, each as amended to date (collectively, the
     "Broadbase Charter Documents"), and each such instrument is in full force
     and effect. Neither Broadbase nor Newco is in violation of any of the
     provisions of the Broadbase Charter Documents. Broadbase has delivered or
     made available to Servicesoft all proposed or considered amendments to the
     Broadbase Charter Documents.

          5.2  Capitalization.

          (a) Authorized/Outstanding Capital Stock. As of the close of business
     on September 11, 2000, the authorized capital stock of Broadbase consisted
     solely of 90,000,000 shares of Broadbase common stock and 5,000,000 shares
     of Broadbase preferred stock. As of the close of business on September 11,
     2000, there were issued and outstanding 47,887,765 shares of Broadbase
     common stock and no shares of Broadbase preferred stock. All issued and
     outstanding shares of Broadbase common stock have been duly authorized and
     validly issued, are fully paid and nonassessable, are not subject to any
     right of rescission, are not subject to preemptive rights by statute,
     Broadbase's certificate of incorporation or bylaws, or any agreement or
     document to which Broadbase is a party or by which it is bound, and have
     been offered, issued, sold and delivered by Broadbase in compliance with
     all registration or qualification requirements (or applicable exemptions
     therefrom) of applicable federal and state securities laws.

          (b) Options/Warrants/Rights. As of the close of business on September
     11, 2000, options to purchase 15,023,519 shares of Broadbase common stock

     Warrants to purchase shares of Broadbase common stock were issued and are
     outstanding as of such date. Between September 11, 2000, and the date of
     this Agreement, Broadbase has not granted any options or warrants or issued
     any shares except pursuant to the acquisitions of Panopticon, Inc. and
     Decisionism, Inc. and as set forth in Item 5.8(b) of the Broadbase
     Disclosure Letter. A list of all holders of Broadbase Options as of
     September 11, 2000, is set forth in Item 5.2(b) of the Broadbase Disclosure
     Letter. Item 5.2(b) of the Broadbase Disclosure Letter lists for each
     person who held Broadbase Options as of September 11, 2000, the exercise
     price for each such Broadbase Option, the number of shares or other
     securities covered by each such Broadbase Option and the term of
     exercisability of each such Broadbase Option. Except as set forth in this
     Section 5.2(b) and in Item 5.2(b) of the Broadbase Disclosure Letter, as of
     the close of business on September 11, 2000, there is no: (i) outstanding
     preemptive right, stock appreciation right, subscription, option, call,
     warrant or right (whether or not currently exercisable) to acquire from
     Broadbase or, to Broadbase's knowledge, from affiliates of Broadbase, any
     shares of the capital stock or other securities of Broadbase; (ii)
     outstanding security, instrument or obligation issued by Broadbase or

     to sell or otherwise issue any shares of its capital stock or any other
     securities; (iv) Contract to which Broadbase is a party relating to the
     voting or registration of or restricting any person from purchasing,
     selling, pledging or otherwise disposing of (or

                                      A-26
<PAGE>   243

     granting any option or similar right with respect to) any shares of
     Broadbase common stock; (v) liability for dividends accrued but unpaid; or
     (vi) condition or circumstance, to Broadbase's knowledge, that likely would
     directly or indirectly give rise to or provide a basis for the assertion of
     a claim by any person to the effect that such person is entitled to acquire
     or receive any shares of capital stock or other securities of Broadbase,
     including, but not limited to, promises to issue or grant securities of
     Broadbase or to recommend to Broadbase's board of directors to issue or
     grant securities of Broadbase. Broadbase is not required to issue any
     shares of Broadbase common stock or options to acquire shares of Broadbase
     common stock in connection with its acquisitions of Panopticon, Inc. and
     Decisionism, Inc. in excess of the amounts set forth in Item 5.2(b) of the
     Broadbase Disclosure Letter.

          (c) The authorized capital stock of Newco consists of 1,000 shares of
     common stock, $0.001 par value per share, all of which, as of the date
     hereof, are issued and outstanding and are held by Broadbase. All of the
     outstanding shares of Newco's common stock have been duly authorized and
     validly issued, and are fully paid and nonassessable. Newco was formed for
     the purpose of consummating the Merger and has no material assets or
     liabilities except as necessary for such purpose.

          (d) The shares of Broadbase common stock to be issued in the Merger,
     when issued in accordance with the provisions of this Agreement, will be
     validly issued, fully paid and non-assessable will not be subject to any
     right of rescission, will not be subject to preemptive rights or rights of
     first refusal by statute, Broadbase's certificate of incorporation or
     bylaws, or any agreement or document to which Broadbase is a party or by
     which it is bound, and will be offered, issued, sold and delivered by
     Broadbase in compliance with all registration or qualification requirements
     (or applicable exemptions therefrom) of applicable federal and state
     securities laws.

          5.3  Power, Authorization and Non-Contravention.

          (a) Each of Broadbase and Newco has the corporate power and authority
     to: (i) carry on its business as now conducted; (ii) own, operate and lease
     its properties in the manner in which its properties are currently owned,
     used and leased and in the manner in which its properties are proposed to
     be owned, used and leased; (iii) perform its obligations under all
     Contracts to which it is a party, and (iv) enter into and perform its
     obligations under this Agreement, and all agreements to which Broadbase or
     Newco is or will be a party that are required to be executed pursuant to
     this Agreement (the "Broadbase Ancillary Agreements"). The execution,
     delivery and performance of this Agreement and the Broadbase Ancillary
     Agreements have been duly and validly approved and authorized by
     Broadbase's Board of Directors and Newco's Board of Directors, as
     applicable. The execution and delivery of this Agreement and the
     consummation of the transactions contemplated hereby have been duly
     authorized by all necessary corporate action on the part of Broadbase and
     Newco, subject only to the approval and adoption of this Agreement and the
     approval of the Merger by Broadbase's stockholders (the "Broadbase
     Stockholder Approval") and the filing of the Certificate of Merger pursuant
     to Delaware Law. The affirmative vote of the holders of a majority in
     interest of the stock present or represented by proxy at a valid meeting of
     Broadbase's stockholders is sufficient for the Broadbase Stockholder
     Approval, and no other approval of any holder of any securities of
     Broadbase is required in connection with the consummation of the
     transactions contemplated hereby.

          (b) No consent, approval, order or authorization of, or registration,
     declaration or filing with any Governmental Entity or other person is
     required to be obtained or made by Broadbase or Newco in connection with
     the execution and delivery of this Agreement or the consummation of the
     Merger, except for (i) the filing of the Certificate of Merger with the
     Secretary of State of the State of Delaware, (ii) the filing with the SEC
     of the Form S-4, the Form S-8 and the Prospectus/Proxy Statement and a
     Current Report on Form 8-K with respect to the Merger, each in accordance
     with the Securities Act and the Exchange Act, and the effectiveness of the
     Form S-4, (iii) the filing with the Nasdaq Stock Market of a Notification
     Form for Listing of Additional Shares with respect to the shares of Parent
     Common Stock issued in the Merger, (iv) such consents, approvals, orders,

                                      A-27
<PAGE>   244

     authorizations, registrations, declarations and filings as may be required
     under applicable federal, foreign and state securities (or related) laws
     and the HSR Act and the securities or antitrust laws of any foreign
     country, and (v) such other consents, authorizations, filings, approvals
     and registrations which if not obtained or made would not be material to
     Broadbase or the Surviving Corporation or prevent, alter or materially
     delay the consummation of the Merger or any of the other transactions
     contemplated hereby.

          (c) This Agreement and the Broadbase Ancillary Agreements are, or when
     executed by Broadbase and Newco (as applicable) and the other parties
     thereto will be, valid and binding obligations of Broadbase and Newco,
     enforceable against Broadbase and Newco in accordance with their respective
     terms, except as to the effect, if any, of (i) applicable bankruptcy and
     other similar laws affecting the rights of creditors generally, (ii) rules
     of law governing specific performance, injunctive relief and other
     equitable remedies and (iii) the enforceability of provisions requiring
     indemnification; provided, however, that the Certificate of Merger and the
     Broadbase Ancillary Agreements will not be effective until the earlier of
     the Effective Time or the date provided for therein.

          5.4  No Violation of Charter Documents, Contracts or Laws. Neither the
     execution and delivery of this Agreement or any Broadbase Ancillary
     Agreement, nor the consummation of the transactions provided for herein or
     therein, will conflict with, or (with or without notice or lapse of time,
     or both) result in a termination, breach, impairment or violation of: (a)
     any provision of the certificate of incorporation, bylaws or other charter
     documents of Broadbase or Newco, as currently in effect; (b) any material
     Broadbase Contract; or (c) any federal, state, local or foreign judgment,
     writ, decree, order, statute, rule or regulation applicable to Broadbase or
     its assets or properties. The consummation of the Merger and succession by
     Broadbase to all rights, licenses, franchises, leases and agreements of
     Broadbase will not require the consent of any third party, and will not
     have a Material Adverse Effect on Broadbase or the Surviving Corporation.

          5.5  SEC Filings.

          (a) Broadbase has filed all forms, reports and documents required to
     be filed by Broadbase with the SEC since the effective date of the
     registration statement of Broadbase's initial public offering, and has made
     available to Servicesoft such forms, reports and documents in the form
     filed with the SEC. All such required forms, reports and documents
     (including those that Broadbase may file subsequent to the date hereof) are
     referred to herein as the "Broadbase SEC Documents." As of their respective
     dates, the Broadbase SEC Documents: (i) were prepared in accordance with
     the requirements of the Securities Act or the Exchange Act, as the case may
     be, and the rules and regulations of the SEC thereunder applicable to such
     Broadbase SEC Documents; and (ii) did not at the time they were filed (or
     if amended or superseded by a filing prior to the date of this Agreement,
     then on the date of such filing) contain any untrue statement of a material
     fact or omit 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, except to the
     extent corrected prior to the date of this Agreement by a subsequently
     filed Broadbase SEC Document. None of Broadbase's subsidiaries is required
     to file any forms, reports or other documents with the SEC.

          5.6  Broadbase Financial Statements. Each of the consolidated
     financial statements (including, in each case, any related notes thereto)
     contained in the Broadbase SEC Documents (the "Broadbase Financial
     Statements"), including any Broadbase SEC Documents filed after the date
     hereof until the Closing: (i) complied (or will comply as of their dates in
     the case of Broadbase SEC Documents filed after the date of this Agreement)
     as to form in all material respects with the published rules and
     regulations of the SEC with respect thereto; (ii) was prepared (or will be
     prepared in the case of Broadbase SEC Documents prepared after the date of
     this Agreement) in accordance with GAAP applied on a consistent basis
     throughout the periods involved (except as may be indicated in the notes
     thereto or, in the case of unaudited interim financial statements, as may
     be permitted by the SEC on Form 10-Q, 8-K or any successor form under the
     Exchange Act); and (iii) fairly presented the

                                      A-28
<PAGE>   245

     consolidated financial position of Broadbase and its subsidiaries as at the
     respective dates thereof and the consolidated results of Broadbase's
     operations and cash flows for the periods indicated, except that the
     unaudited interim financial statements may not contain footnotes and were
     or are subject to normal and recurring year-end adjustments. The balance
     sheet of Broadbase contained in the Broadbase SEC Documents as of June 30,
     2000 is hereinafter referred to as the "Broadbase Balance Sheet", with June
     30, 2000 hereinafter referred to as the Broadbase Balance Sheet Date.
     Except as disclosed in the Broadbase Financial Statements, since the date
     of the Broadbase Balance Sheet neither Broadbase nor any of its
     subsidiaries has any liabilities required under GAAP to be set forth on a
     balance sheet (absolute, accrued, contingent or otherwise) which are,
     individually or in the aggregate, material to the business, results of
     operations or financial condition of Broadbase and its subsidiaries taken
     as a whole, except for liabilities incurred since the date of the Broadbase
     Balance Sheet in the ordinary course of business consistent with past
     practices and liabilities incurred in connection with this Agreement. There
     has been no change in Broadbase's accounting policies, except as described
     in the notes to the Broadbase Financial Statements.

          5.7  Litigation. There is no action, suit, arbitration, mediation,
     proceeding, claim or, to Broadbase's knowledge, investigation pending, nor,
     to Broadbase's knowledge, are any of the foregoing threatened against
     Broadbase or Newco before any court, administrative agency or arbitrator
     that, if determined adversely to Broadbase or Newco, may reasonably be
     expected to have a Material Adverse Effect on Broadbase or Newco. There is
     no judgment, decree, injunction or ruling of an administrative agency or
     arbitrator outstanding against Broadbase or Newco, except as may reasonably
     be expected to have a Material Adverse Effect on Broadbase or Newco. As of
     the date hereof, there is no action, suit, proceeding, claim, arbitration
     or investigation pending as to which Broadbase or Newco has received notice
     of assertion against Broadbase or Newco, which in any manner challenges or
     seeks to prevent, enjoin, alter or materially delay any of the transactions
     contemplated by this Agreement. To the knowledge of Broadbase, there is no
     basis for any person, firm, corporation or entity to assert a claim against
     Broadbase or any subsidiary of Broadbase based upon rights to ownership of
     any shares of Broadbase common stock or any option, warrant or other right
     to acquire any shares of Broadbase common stock, other than shares,
     options, warrants or rights included in the amounts therefor set forth in
     Section 5.2.

          5.8  Absence of Certain Changes or Events. Since the Broadbase Balance
     Sheet Date, Broadbase has carried on its business in the ordinary course
     substantially in accordance with the procedures and practices in effect on
     the Broadbase Balance Sheet Date.

          (a) Except as set forth in Item 5.8 of the Broadbase Disclosure
     Letter, since the Broadbase Balance Sheet Date there has not been any
     change, circumstance or effect that is or is reasonably likely to be
     materially adverse to the business, employees, assets (including intangible
     assets), capitalization, financial condition, operations or results of
     operations of Broadbase and its subsidiaries, taken as a whole.

          (b) Except as set forth in Item 5.8 or permitted by the terms of this
     Agreement, since the Broadbase Balance Sheet Date, Broadbase has not:

             (i) amended its certificate of incorporation, bylaws or any other
        charter document;

             (ii) declared, set aside or paid any dividend on, or made any other
        distribution in respect of, its capital stock, or made any changes in
        any rights, preferences, privileges or restrictions of any of its
        outstanding capital stock;

             (iii) effected any split, stock dividend, combination or
        recapitalization of its capital stock or any direct or indirect
        redemption, purchase or other acquisition by Broadbase of its capital
        stock; or

             (iv) consummated any transaction relating to a merger,
        consolidation, sale of all or substantially all of its assets;

                                      A-29
<PAGE>   246

             (v) incurred any obligation or liability to any of its officers,
        directors, stockholders or affiliates, or made any loans or advances to
        any of its officers, directors, stockholders or affiliates, except
        normal compensation and expense allowances payable to officers or
        directors;

             (vi) sold, issued, granted or authorized the issuance or grant of:
        (A) any shares of its capital stock of any class or other security
        (other than (1) options issued to employees in the ordinary course of
        business consistent with past practice, or (2) pursuant to exercise of
        outstanding stock options); (B) any option, call, warrant, obligation,
        subscription, or other right to acquire any capital stock or any other
        security or (C) any instrument convertible into or exchangeable for any
        capital stock or other security; or accelerated the vesting of any
        outstanding option or other security;

             (vii) made or entered into any agreement or understanding to do any
        of the foregoing other than as disclosed in Item 5.8 of the Broadbase
        Disclosure Letter.

          5.9  Intellectual Property.

          (a) Ownership of Intellectual Property. Broadbase owns all right,
     title and interest in, or has the right to use, all Intellectual Property
     Rights used in or reasonably necessary to the conduct of its business as
     presently conducted and the business of the licensing and use of Broadbase
     products and the sale of commercial services using such Intellectual
     Property Rights (with such Intellectual Property Rights being hereinafter
     collectively referred to as the "Broadbase IP Rights"). The execution,
     delivery and performance of this Agreement and the consummation of the
     transactions contemplated hereby will not constitute a material breach of
     any instrument or agreement governing any Broadbase IP Right, will not
     cause forfeiture or termination or give rise to a right of forfeiture or
     termination of any Broadbase IP Right or materially impair the right of
     Servicesoft to use, sell or license any Broadbase IP Right or portion
     thereof.

          (b) No Violation of Rights of Others. The business of Broadbase, as
     conducted as of the date hereof, does not, and the business of the
     licensing and use of Broadbase products, and the sale of Broadbase
     commercial services after the Effective Time will not, cause Broadbase to
     infringe or violate any of the Intellectual Property Rights of any other
     person. Broadbase has not received any written or oral claim or notice of
     infringement or potential infringement of the Intellectual Property Rights
     of any other person which could be reasonably expected to have a Material
     Adverse Effect on Broadbase. To its knowledge, Broadbase is not using any
     confidential information or trade secrets of any past or present employees.

          (c) Protection of Rights. Broadbase has taken reasonable and
     practicable steps designed to safeguard and maintain the secrecy and
     confidentiality of, and its proprietary rights in, all Broadbase IP Rights.
     To the knowledge of Broadbase, there is no material unauthorized use,
     infringement or misappropriation of any Broadbase IP Rights by any third
     party, including, to the knowledge of Broadbase, any Broadbase employee.
     Except as set forth in Item 5.9(c), Broadbase is not aware of any
     infringement of any Broadbase IP Rights by any third party. All officers,
     employees and consultants of Broadbase and its subsidiaries (other (i) than
     employees and consultants who are not and have not been involved in
     developing Broadbase IP Rights or providing services to customers and who
     have no managerial responsibilities and (ii) officers, employees and
     consultants of Panopticon, Inc. and Decisionism, Inc.) have executed and
     delivered to Broadbase an agreement regarding the protection of proprietary
     information and the assignment to Broadbase of all Intellectual Property
     Rights arising from the services provided for Broadbase or any subsidiary
     of Broadbase by such persons.

          5.10  Compliance with Laws. Broadbase has complied, or prior to the
     Closing Date will have complied, and is or will be at the Closing Date in
     compliance, in all respects material to Broadbase, with all applicable
     laws, ordinances, regulations and rules, and all orders, writs,
     injunctions, awards,

                                      A-30
<PAGE>   247

     judgments and decrees, applicable to Broadbase, or to the assets,
     properties and business of Broadbase, including, without limitation:

             (a) all applicable federal and state securities laws and
        regulations;

             (b) all applicable federal, state and local laws, ordinances and
        regulations, and all orders, writs, injunctions, awards, judgments and
        decrees, pertaining to (i) the sale, licensing, leasing, ownership or
        management of Broadbase's owned, leased or licensed real or personal
        property, products or technical data, (ii) employment or employment
        practices, terms and conditions of employment, or wages and hours or
        (iii) safety, health, fire prevention, environmental protection
        (including toxic waste disposal and related matters described in Section
        4.16), building standards, zoning or other similar matters;

             (c) the Export Administration Act and regulations promulgated
        thereunder or other laws, regulations, rules, orders, writs,
        injunctions, judgments or decrees applicable to the export or re-export
        of controlled commodities or technical data;

             (d) the Immigration Reform and Control Act; and

             (e) all governmental and nongovernmental regulations related to the
        operation and use of the Internet.

          Broadbase has received all material permits and approvals from, and
     has made all material filings with, third parties, including government
     agencies and authorities, that are necessary to the conduct of its business
     as presently conducted.

          5.11  Information Supplied. None of the information supplied or to be
     supplied by Broadbase for inclusion in the Form S-4 and the
     Prospectus/Proxy Statement, at the date such information is supplied, at
     the time of the meeting of the stockholders of Broadbase to approve the
     Merger, and at the time of the meeting, or the date of the written consent,
     of the Servicesoft Stockholders to approve the Merger, contains or will
     contain any untrue statement of a material fact or omits or will omit to
     state any material fact required to be stated therein or necessary in order
     to make the statements therein, in light of the circumstances under which
     they are made, not misleading, or will, in the case of the Form S-4, at the
     time the Form S-4 becomes effective under the Securities Act, contains any
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they are made, not misleading.

          5.12  Accuracy of Disclosure. The representations and warranties
     contained in this Agreement, taken together with the Broadbase Disclosure
     Letter and any exhibits, schedules, certificates and documents to be
     delivered by Broadbase to Servicesoft pursuant to this Agreement, do not
     contain any untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements contained herein and
     therein, in light of the circumstances under which such statements were
     made, not misleading.

     6. Servicesoft Pre-closing Covenants

     During the period from the date of this Agreement until the earlier to
occur of (a) the Effective Time and (b) the termination of this Agreement in
accordance with the provisions of Article 11 hereof, Servicesoft covenants to
and agrees with Broadbase (and, where Broadbase explicitly agrees to perform
certain actions pursuant to specific provisions in this Article 6, Broadbase
covenants to and agrees with Servicesoft) as follows:

          6.1  Access to Information. Until the Closing Date and subject to the
     terms and conditions hereof relating to the confidentiality and use of
     confidential and proprietary information, Servicesoft will provide
     Broadbase and its agents with reasonable access, during regular business
     hours, to the files, books, records and offices of Servicesoft and the
     Subsidiaries, including, without limitation, any and all information
     relating to Servicesoft and Subsidiary taxes, commitments, Contracts,
     leases,

                                      A-31
<PAGE>   248

     licenses, real, personal and intangible property, and financial condition.
     Servicesoft will cause its accountants to cooperate with Broadbase and its
     agents in making available all financial information reasonably requested,
     including, without limitation, the right to examine all working papers
     pertaining to all financial statements prepared or audited by such
     accountants.

          6.2  Advice of Changes. Servicesoft will promptly advise Broadbase in
     writing of: (i) the discovery by Servicesoft of any event, condition, fact
     or circumstance occurring on or prior to the date of this Agreement that
     would render any representation or warranty by Servicesoft contained in
     this Agreement untrue or inaccurate in any material respect; (ii) any
     event, condition, fact or circumstance occurring subsequent to the date of
     this Agreement that would render any representation or warranty by
     Servicesoft contained in this Agreement, if made on or as of the date of
     such event or the Closing Date, untrue or inaccurate in any material
     respect; (iii) any breach of any covenant or obligation of Servicesoft
     pursuant to this Agreement or any Ancillary Agreement; (iv) any event,
     condition, fact or circumstance that may make the timely satisfaction of
     any of the conditions set forth in Article 10 impossible or unlikely; and
     (v) any Material Adverse Effect on Servicesoft.

          6.3  Conduct of Business. During the period from the date of this
     Agreement and continuing until the earlier of the termination of this
     Agreement pursuant to its terms or the Effective Time, Servicesoft and each
     of its subsidiaries shall, except to the extent that Broadbase shall
     otherwise consent in writing, carry on its business in the usual, regular
     and ordinary course, in substantially the same manner as heretofore
     conducted and in compliance in all material respects with all applicable
     laws and regulations, pay its debts and Taxes when due, pay or perform
     other material obligations when due, and use all reasonable efforts
     consistent with past practices and policies to (i) preserve intact its
     present business organization, (ii) keep available the services of its
     present officers, (iii) preserve its relationships with customers,
     suppliers, licensors, licensees, and others with which it has business
     dealings, (iv) maintain its equipment and other assets in good working
     condition and repair according to the standards it has maintained to the
     date of this Agreement, subject only to ordinary wear and tear, and (v)
     keep in full force all insurance policies identified in Item 4.20 of the
     Servicesoft Disclosure Letter and obtain any additional insurance required
     consistent with past practices for its business and property. In addition,
     during that period, Servicesoft will promptly notify Broadbase of any
     material event involving its business or operations consistent with the
     agreements contained herein.

          In addition, except as provided otherwise herein or as approved or
     recommended by Broadbase, Servicesoft will not, without the prior written
     consent of an executive officer of Broadbase, which consent shall not be
     unreasonably withheld or delayed:

             (a) sell, lease, license, encumber or otherwise dispose of any
        properties or assets which are material, individually or in the
        aggregate, to the business of Servicesoft and its Subsidiaries or which

        or indebtedness exceed $250,000 in the aggregate; provided, however,

        with a nationally recognized financial institution on reasonable terms;

             (c) enter into any licensing or other agreement with regard to the

        the terms of which transactions are not in the ordinary course of
        business consistent with past practice;

             (m) waive any stock repurchase rights, accelerate, amend or change

          Notwithstanding any provision to the contrary contained herein, in the
     event that Broadbase does not comply with its obligation to provide
     Servicesoft with Loans as required under Section 7.12, then Servicesoft
     shall be entitled to borrow up to $15 million or issue equity securities
     for net proceeds of up to $15 million on such terms as Servicesoft may deem
     appropriate, provided that in the event of any issuance of equity
     securities, rights to acquire equity securities or convertible securities,
     appropriate adjustment shall be made to the Conversion Ratio so that the
     percentage of the fully-diluted outstanding common stock of Broadbase owned
     in aggregate by the Servicesoft Stockholders and former holders of
     Servicesoft options and warrants immediately following the Effective Time
     (determined using the treasury method) will not be increased as a result of
     such issuance; and provided further that such transaction does not involve
     an Acquisition Transaction.

          6.4  Prospectus/Proxy Statement.

          (a) SEC Filings. As promptly as practicable after the execution of
     this Agreement, Servicesoft and Broadbase will prepare and file with the
     SEC, the Prospectus/Proxy Statement and Broadbase will prepare and file
     with the SEC the Form S-4 in which the Prospectus/Proxy Statement will be
     included. Each of Servicesoft and Broadbase will respond to any comments of
     the SEC, will use its

                                      A-34
<PAGE>   251

     respective reasonable efforts to have the Form S-4 registration statement
     declared effective under the Securities Act as promptly as practicable
     after such filing, and each of Servicesoft and Broadbase will cause the
     Prospectus/Proxy Statement to be mailed to its respective stockholders at
     the earliest practicable time after the Registration Statement is declared
     effective by the SEC. Each of Servicesoft and Broadbase will promptly
     provide all information relating to its business or operations necessary
     for inclusion in the Form S-4 and Prospectus/Proxy Statement to satisfy all
     requirements of applicable state and federal securities laws, and will be
     solely responsible for any statement, information or omission in the
     Prospectus/Proxy Statement relating to it or its affiliates based upon
     written information furnished by it. Servicesoft will not provide or
     publish to its stockholders any material concerning it or its affiliates
     that violates the Securities Act or Exchange Act with respect to the
     transactions contemplated hereby.

          (b) HSR Filings. As promptly as practicable after the date of this
     Agreement, each of Servicesoft and Broadbase will prepare and file (i) with
     the United States Federal Trade Commission and the Antitrust Division of
     the United States Department of Justice Notification and Report Forms
     relating to the transactions contemplated herein if required by the HSR
     Act, as well as comparable pre-merger notification forms required by the
     merger notification or control laws and regulations of any applicable
     jurisdiction, as agreed to by the parties (the "Antitrust Filings") and
     (ii) any other filings required to be filed by it under the Exchange Act,
     the Securities Act or any other Federal, state or foreign laws relating to
     the Merger and the transactions contemplated by this Agreement (the "Other
     Filings"). Servicesoft and Broadbase each shall promptly supply the other
     with any information which may be required in order to effectuate any
     filings pursuant to this Section 6.4. Neither Broadbase nor Servicesoft nor
     any of their respective affiliates shall be under any obligation to make
     proposals, execute or carry out agreements or submit to orders providing
     for the sale or other disposition or holding separate (through the
     establishment of a trust or otherwise) of any assets or categories of
     assets of Broadbase or Servicesoft, any of their respective affiliates or
     subsidiaries, or the holding separate of the shares of Servicesoft capital
     stock to be acquired or the Exchange Shares, or imposing or seeking to
     impose any limitation on the ability of Broadbase or Servicesoft or any of
     their respective subsidiaries or affiliates to conduct their business or
     own such assets or to acquire, hold or exercise full rights of ownership of
     the shares of Servicesoft capital stock to be acquired by Broadbase or the
     Exchange Shares to be issued to Servicesoft Stockholders.

          (c) Joint Participation. Each of Servicesoft and Broadbase will notify
     the other promptly upon the receipt of any comments from the SEC or its
     staff or any other government officials in connection with any filing made
     pursuant hereto and of any request by the SEC or its staff or any other
     government officials for amendments or supplements to the Form S-4, the
     Prospectus/Proxy Statement or any Antitrust Filings or Other Filings or for
     additional information and will supply the other with copies of all
     correspondence between such party or any of its representatives, on the one
     hand, and the SEC, or its staff or any other government officials, on the
     other hand, with respect to the Form S-4, the Prospectus/Proxy Statement,
     the Merger or any Antitrust Filing or Other Filing. Each of Servicesoft and
     Broadbase will cause all documents that it is responsible for filing with
     the SEC or other regulatory authorities under this Section 6.5 to comply in
     all material respects with all applicable requirements of law and the rules
     and regulations promulgated thereunder. Whenever any event occurs which is
     required to be set forth in an amendment or supplement to the Prospectus/
     Proxy Statement, the Form S-4 or any Antitrust Filing or Other Filing,
     Servicesoft or Broadbase, as the case may be, will promptly inform the
     other of such occurrence and cooperate in filing with the SEC or its staff
     or any other government officials, and/or mailing to stockholders of the
     Servicesoft and/or Broadbase, such amendment or supplement.

          6.5  Stockholder Approval.

          (a) Servicesoft will hold a special meeting or solicit written consent
     of the Servicesoft Stockholders as promptly as practicable, and in any
     event (to the extent permissible under applicable law) no more than forty
     (40) days after the SEC has declared the Form S-4 effective. Servicesoft
     will solicit from the Servicesoft Stockholders proxies in favor of the
     approval of this Agreement and

                                      A-35
<PAGE>   252

     the Merger, and, subject to the fiduciary obligations of Servicesoft's
     directors, Servicesoft will use all reasonable efforts to take all other
     action necessary or advisable to secure the vote or consent of the
     Servicesoft Stockholders required under Delaware Law to obtain such
     approvals. Any meeting of the Servicesoft Stockholders shall be called,
     held and conducted, and any proxies or shareholder written consents will be
     solicited, in compliance with all applicable federal laws, Delaware Law and
     Servicesoft's certificate of incorporation and bylaws, and all other
     applicable legal requirements. Servicesoft's obligation to call, give
     notice of, convene, hold and conduct the Servicesoft Stockholders Meeting
     (as defined in Section 6.5(b)) or solicit a written consent of the
     Servicesoft Stockholders in accordance with this Section 6.5 shall not be
     limited or otherwise affected by the commencement, disclosure, announcement
     or submission to Servicesoft of any Acquisition Proposal (as defined in
     Section 6.6(a)) or Superior Offer (as defined in Section 6.5(d)), or by any
     withdrawal, amendment or modification of the recommendation of the Board of
     Directors of Servicesoft to the Servicesoft Stockholders to approve this
     Agreement and the Merger.

          (b) In the event a meeting of the Servicesoft Stockholders is held to
     approve this Agreement and the Merger (the "Servicesoft Stockholders
     Meeting"), then notwithstanding anything to the contrary contained in this
     Agreement, Servicesoft may adjourn or postpone the Servicesoft Stockholders
     Meeting if as of the time for which the Servicesoft Stockholders Meeting is
     originally scheduled there are insufficient shares of Servicesoft capital
     stock represented (either in person or by proxy) to constitute a quorum
     necessary to conduct the business of the Servicesoft Stockholders Meeting,
     in which case the Servicesoft Stockholders Meeting shall be re-convened as
     soon as a quorum is available. Servicesoft shall ensure that the
     Servicesoft Stockholders Meeting is called, noticed, convened, held and
     conducted prior to and separate from any meeting of the Servicesoft
     Stockholders at which any Acquisition Proposal or Acquisition Transaction
     (as defined in Section 6.6(a)) is considered or voted upon.

          (c) Subject to Section 6.5(d): (i) the Board of Directors of
     Servicesoft shall unanimously recommend that the Servicesoft Stockholders
     approve this Agreement and the Merger; (ii) the Form S-4 and
     Prospectus/Proxy Statement, and the written consent of stockholders, if
     any, shall include a statement to the effect that the Board of Directors of
     Servicesoft has recommended that the Servicesoft Stockholders approve this
     Agreement and the Merger; and (iii) neither the Board of Directors of
     Servicesoft nor any committee thereof shall withdraw, amend or modify, or
     propose or resolve to withdraw, amend or modify in a manner adverse to
     Broadbase, the recommendation of the Board of Directors of Servicesoft that
     the Servicesoft Stockholders vote in favor of and approve this Agreement
     and the Merger.

          (d) Nothing in this Agreement shall prevent the Board of Directors of
     Servicesoft from withholding, withdrawing, amending or modifying its
     recommendation in favor of the Merger if (i) a Superior Offer (as defined
     below) is made to Servicesoft and is not withdrawn, (ii) Servicesoft shall
     have provided written notice to Broadbase (a "Notice of Superior Offer")
     advising Broadbase that Servicesoft has received a Superior Offer,
     specifying all of the material terms and conditions of such Superior Offer
     and identifying the person or entity making such Superior Offer, (iii)
     Broadbase shall not have, within three business days of Broadbase's receipt
     of the Notice of Superior Offer, made an offer that Servicesoft's Board of
     Directors by a majority vote determines in its good faith judgment (based
     on the written advice of a financial advisor of national standing) to be at
     least as favorable to Servicesoft's stockholders as such Superior Offer (it
     being agreed that the Board of Directors of Servicesoft shall convene a
     meeting to consider any such offer by Broadbase promptly following the
     receipt thereof), (iv) the Board of Directors of Servicesoft concludes in
     good faith, after consultation with its outside counsel, that, in light of
     such Superior Offer, the withholding, withdrawal, amendment or modification
     of such recommendation is required in order for the Board of Directors of
     Servicesoft to comply with its fiduciary obligations to Servicesoft's
     stockholders under applicable law and (v) Servicesoft shall not have
     violated any of the restrictions set forth in Section 6.6 or this Section
     6.5. Servicesoft shall provide Broadbase with at least two business days
     prior notice (or such lesser prior notice as provided to the members of
     Servicesoft's Board of Directors but in no event less than

                                      A-36
<PAGE>   253

     twenty-four hours) of any meeting of Servicesoft's Board of Directors at
     which Servicesoft's Board of Directors is reasonably expected to consider
     any Acquisition Proposal to determine whether such Acquisition Proposal is
     a Superior Offer. Nothing contained in this Section 6.5(d) shall limit
     Servicesoft's obligation to hold and convene Servicesoft Stockholders'
     Meeting (regardless of whether the recommendation of the Board of Directors
     of Servicesoft shall have been withdrawn, amended or modified). For
     purposes of this Agreement, "Superior Offer" shall mean an unsolicited,
     bona fide offer made by a third party to consummate any of the following
     transactions: (i) a merger or consolidation involving Servicesoft pursuant
     to which the stockholders of Servicesoft immediately preceding such
     transaction hold less than 50% of the equity interest in the surviving or
     resulting entity of such transaction or (ii) the acquisition by any person
     or group (including by way of a tender offer or an exchange offer or a two
     step transaction involving a tender offer followed with reasonable
     promptness by a merger involving Servicesoft), directly or indirectly, of
     ownership of 100% of the then outstanding shares of capital stock of
     Servicesoft, on terms that the Board of Directors of Servicesoft
     determines, in its reasonable judgment (based on the written advice of a
     financial advisor of national standing) to be more favorable to Servicesoft
     stockholders than the terms of the Merger; provided, however, that any such
     offer shall not be deemed to be a "Superior Offer" if any financing
     required to consummate the transaction contemplated by such offer is not
     committed and is not likely in the reasonable judgment of Servicesoft's
     Board of Directors (based on the advice of its financial advisor) to be
     obtained by such third party on a timely basis.

          6.6  No Solicitation.

          (a) Definitions.

          (i) "Acquisition Proposal" means any offer or proposal (other than an
     offer or proposal by Broadbase) relating to an Acquisition Transaction with
     respect to Servicesoft.

          (ii) "Acquisition Transaction" with respect to any entity means any
     transaction or series of related transactions other than the transactions
     contemplated by this Agreement involving: (a) any acquisition or purchase
     from such entity by any person or "group" (as defined under Section 13(d)
     of the Exchange Act and the rules and regulations thereunder) of more than
     a 15% interest in the total outstanding voting securities of such entity or
     any of its subsidiaries or any tender offer or exchange offer that if
     consummated would result in any person or "group" (as defined under Section
     13(d) of the Exchange Act and the rules and regulations thereunder)
     beneficially owning 15% or more of the total outstanding voting securities
     of such entity, or any of its subsidiaries or any merger, consolidation,
     business combination or similar transaction involving such entity; (b) any
     sale, lease (other than in the ordinary course of business), exchange,
     transfer, license (other than in the ordinary course of business),
     acquisition or disposition of more than 10% of the assets of such entity;
     or (c) any liquidation or dissolution of such entity.

          (b) From and after the date of this Agreement until the Effective Time
     or termination of this Agreement pursuant to Article 11, Servicesoft and
     its Subsidiaries will not, nor will they authorize or permit any of their
     respective officers, directors, affiliates or employees or any investment
     banker, attorney or other advisor or representative retained by any of them
     to, directly or indirectly:

             (i) solicit, or initiate the making, submission or announcement of
        any Acquisition Proposal;

             (ii) furnish to any person any non-public information with respect
        to any Acquisition Proposal or take any other action to facilitate any
        inquiries regarding any Acquisition Proposal;

             (iii) participate or engage in any discussions or negotiations with
        any person with respect to any Acquisition Proposal, except that
        Servicesoft may inform third parties, in response to unsolicited
        inquiries, of the existence of these provisions;

             (iv) approve, endorse or recommend any Acquisition Proposal
        (except, in the case of a Superior Offer, if (1) neither Servicesoft nor
        any representative of Servicesoft and its Subsidiaries shall have
        violated any of the restrictions set forth in this Section 6.6 and (2)
        the

                                      A-37
<PAGE>   254

        Board of Directors of Servicesoft concludes in good faith, after
        consultation with its outside legal counsel, that it must approve,
        endorse or recommend such Superior Offer in order for it to comply with
        its fiduciary obligations to Servicesoft's stockholders under applicable
        law); or

             (v) enter into any letter of intent or similar document or any
        Contract contemplating or otherwise relating to any Acquisition
        Transaction;

        provided, however, that notwithstanding the foregoing, prior to the
        approval of this Agreement and the Merger at the Servicesoft
        Stockholders' Meeting, this Section 6.6(b) shall not prohibit
        Servicesoft from furnishing nonpublic information regarding Servicesoft
        and its Subsidiaries to, or entering into discussions or negotiations
        with, any person or group who has submitted (and not withdrawn) to
        Servicesoft an unsolicited, written, bona fide Acquisition Proposal that
        the Board of Directors of Servicesoft reasonably concludes (based on the
        written advice of a financial advisor of national standing) may
        constitute a Superior Offer if (1) neither Servicesoft nor any
        representative of Servicesoft and its Subsidiaries shall have violated
        any of the restrictions set forth in this Section 6.6, (2) the Board of
        Directors of Servicesoft concludes in good faith, after consultation
        with its outside legal counsel, that such action is required in order
        for the Board of Directors of Servicesoft to comply with its fiduciary
        obligations to Servicesoft's stockholders under applicable law, (3)
        prior to furnishing any such nonpublic information to, or entering into
        any such discussions with, such person or group, Servicesoft gives
        Broadbase written notice of the identity of such person or group and all
        of the material terms and conditions of such Acquisition Proposal and of
        Servicesoft's intention to furnish nonpublic information to, or enter
        into discussions with, such person or group, and Servicesoft receives
        from such person or group an executed confidentiality agreement
        containing terms at least as restrictive with regard to Servicesoft's
        confidential information as the confidentiality agreement entered into
        by the parties hereto, (4) Servicesoft gives Broadbase at least two
        business days advance notice of its intent to furnish such nonpublic
        information or enter into such discussions, and (5) contemporaneously
        with furnishing any such nonpublic information to such person or group,
        Servicesoft furnishes such nonpublic information to Broadbase (to the
        extent such nonpublic information has not been previously furnished by
        Servicesoft to Broadbase). Servicesoft and its Subsidiaries will
        immediately cease any and all existing activities, discussions or
        negotiations with any parties conducted heretofore with respect to any
        Acquisition Proposal. Without limiting the foregoing, it is understood
        that any violation of the restrictions set forth in the preceding two
        sentences by any officer, director or employee of Servicesoft or any of
        its Subsidiaries or any investment banker, attorney or other advisor or
        representative of Servicesoft or any of its Subsidiaries shall be deemed
        to be a breach of this Section 6.6 by Servicesoft; provided that if such
        violation consists of a communication by any such advisor which was
        unauthorized by Servicesoft and Servicesoft terminates its relationship
        with such advisor and with such advisor's employer immediately upon
        becoming aware of such communication, then such from and after such
        termination, then such communication shall no longer be deemed to
        constitute a material breach of this Agreement for purposes of Sections
        10.2 and 11.1(a)(ii).

          (c) In addition to the obligations of Servicesoft set forth in Section
     6.6(b), Servicesoft as promptly as practicable shall advise Broadbase
     orally and in writing of any request for non-public information or any
     other inquiry which Servicesoft believes is likely to lead to an
     Acquisition Proposal or of any Acquisition Proposal, the material terms and
     conditions of such request, inquiry or Acquisition Proposal, and the
     identity of the person or group making any such request, inquiry or
     Acquisition Proposal. Servicesoft will keep Broadbase informed as promptly
     as practicable in all material respects of amendments to any such request,
     inquiry or Acquisition Proposal.

          6.7  Regulatory Approvals. Servicesoft will execute and file, or join
     in the execution and filing, of any application or other document that may
     be necessary in order to obtain the authorization, approval or consent of
     any governmental body, federal, state, local or foreign, which may be
     reasonably required, or which Broadbase may reasonably request, in
     connection with the consumma-

                                      A-38
<PAGE>   255

     tion of the transactions provided for in this Agreement. Servicesoft will
     use all reasonable efforts to obtain or assist Broadbase in obtaining all
     such authorizations, approvals and consents.

          6.8  Necessary Consents. Servicesoft will use all reasonable efforts
     to obtain such written consents and take such other actions as may be
     necessary or appropriate for Servicesoft, in addition to those set forth in
     Section 6.4, to allow the consummation of the transactions provided for
     herein and to facilitate and allow Broadbase to carry on Servicesoft's
     business after the Closing Date.

          6.9  Blue Sky Laws. Servicesoft shall use all reasonable efforts to
     assist Broadbase to the extent necessary to comply with the securities and
     Blue Sky laws of all jurisdictions applicable in connection with the
     Merger.

          6.10  Servicesoft Dissenting Shares. As promptly as practicable after
     the date the Prospectus/Proxy Statement is distributed to Servicesoft
     Stockholders and prior to the Closing Date, Servicesoft shall furnish
     Broadbase with the name and address of each Servicesoft Stockholder who has
     up to such time dissented and the number of shares owned by such
     Servicesoft Stockholders.

          6.11  Litigation. Servicesoft will notify Broadbase in writing
     promptly after learning of any material action, suit, proceeding or
     investigation by or before any court, board or governmental agency,
     initiated by or against Servicesoft or threatened against it. In addition,
     Servicesoft will notify Broadbase in writing promptly after learning of any
     action, suit, proceeding, claim, arbitration or investigation threatened or
     pending for the purpose or with the probable effect of enjoining or
     preventing the consummation of any of the transactions contemplated by this
     Agreement, or which would be reasonably expected to have a Material Adverse
     Effect on Broadbase. If Servicesoft becomes subject to a review by the
     Internal Revenue Service or any other taxing agency or authority for
     accounting periods prior to the Closing Date (including but not limited to
     any short tax year resulting from the Merger), then Servicesoft
     acknowledges that Broadbase will be entitled to participate in such review.
     Servicesoft will not enter into any settlement or other stipulation with
     respect to any such review without the written consent of Broadbase, which
     consent will not be unreasonably withheld.

          6.12  Certain Employee Benefits. As soon as practicable after the
     execution of this Agreement, Servicesoft and Broadbase shall confer and
     work together in good faith to agree upon mutually acceptable employee
     benefit and compensation arrangements for employees of Servicesoft and its
     Subsidiaries following the Merger. Servicesoft shall take such actions as
     are necessary to terminate such Servicesoft Employee Plans as are requested
     by Broadbase to be terminated, provided that those employees of Servicesoft
     and its Subsidiaries who are eligible to participate in each such
     Servicesoft Employee Plan shall be provided the opportunity to participate
     in a substantially comparable employee benefit plan maintained by Broadbase
     and provided further that Broadbase requests such termination no later than
     ten days prior to the Closing Date. Servicesoft agrees that it shall
     terminate any and all group severance, separation, retention and salary
     continuation plans, programs or arrangements (other than the Employment
     Agreements) prior to the Closing.

          6.13  Notification of Employee Problems. Servicesoft will promptly
     notify Broadbase if any of Servicesoft's officers becomes aware that any of
     its officers and software developer managers, or any material number of
     other employees intends or threatens to leave its employ.

          6.14  Certain Agreements. Servicesoft will use all reasonable efforts
     to cause all present employees and consultants of Servicesoft who have not
     previously executed Servicesoft's forms of assignments of copyright and
     other intellectual property rights to Servicesoft to execute such forms.

          6.15  Servicesoft Affiliates. To help ensure that the issuance of the
     Exchange Shares complies with the Securities Act, prior to the Closing Date
     Servicesoft will deliver a letter identifying all persons who are, in
     Servicesoft's reasonable judgment, "affiliates" of Servicesoft at that time
     (the "Servicesoft Affiliates"). Servicesoft will provide Broadbase with all
     information and documents needed to evaluate this list for compliance with
     securities laws. Broadbase will cause the Exchange

                                      A-39
<PAGE>   256

     Shares issued to the Servicesoft Affiliates to bear legends with respect to
     any application limitations on transfer under Rule 145 promulgated under
     the Securities Act.

          6.16  Satisfaction of Closing Conditions. Servicesoft will use all
     reasonable efforts to satisfy or cause to be satisfied all the conditions
     precedent which are set forth in Article 10 or elsewhere in this Agreement
     on or before the Closing. Servicesoft will use all reasonable efforts to
     cause the transactions contemplated by this Agreement to be consummated,
     and, without limiting the generality of the foregoing, to obtain all
     consents and authorizations of third parties and to make all filings with,
     and give all notices to, third parties that may be necessary or reasonably
     required on its part in order to effect the transactions contemplated
     hereby.

          6.17  Conversion of Servicesoft Preferred Stock and Servicesoft
     Warrants. Servicesoft agrees to solicit from the holders of each series of
     Servicesoft Canada Preferred Stock consent to exchange all of the shares of
     Servicesoft Canada Preferred Stock into shares of Servicesoft Series H
     Preferred Stock prior to the Effective Time of the Merger. Servicesoft
     further agrees to solicit from the holders of each series of Servicesoft
     Preferred Stock consent to convert all of the shares of Servicesoft
     Preferred Stock (other than the Servicesoft Series X Preferred Stock and
     Servicesoft Series Y Preferred Stock) into shares of Servicesoft Common
     Stock prior to the Effective Time, and to use all reasonable efforts to
     cause such conversion. In addition, Servicesoft agrees to use all
     reasonable efforts to cause each holder of Servicesoft Warrants to
     exercise, effective as of, and contingent upon, the consummation of the
     Merger, all Servicesoft Warrants beneficially owned by such person in full
     in accordance with the terms of such Servicesoft Warrants. Subject to
     Section 7.18, Servicesoft shall use all reasonable efforts to cause each
     share of Servicesoft Canada Preferred Stock and Servicesoft Canada Common
     Stock to be exchanged, prior to the Effective Time of the Merger, for
     shares of Servicesoft Preferred Stock and Servicesoft Common Stock,
     respectively, in accordance with the terms of such Servicesoft Canada
     Preferred Stock and the constituent documents of Servicesoft Canada.

          6.18  Confirmation of Equity Interests. Prior to the Effective Time
     (and, in the case of any convertible securities which are to be converted,
     or warrants which are to be exercised, prior to the Effective Time, prior
     to such conversion or exercise), Servicesoft will provide Broadbase with
     such information and documents as Broadbase may from time to time
     reasonably request with respect to the calculations of antidilution
     adjustments, dividends and share and warrant issuances that are reflected
     in the Servicesoft Disclosure Letter. If, prior to the Effective Time, any
     person shall notify Servicesoft of its election to exercise any warrants or
     convert any convertible securities of Servicesoft, or exchange any
     Servicesoft Canada Preferred Stock or Servicesoft Canada Common Stock for
     Servicesoft Capital Stock, in each case where the terms of such exercise or
     conversion would give effect to any antidilution adjustments or dividends
     by Servicesoft, or where the number of shares to be issued upon such
     exercise or conversion would differ from the number set forth or reflected
     in the Servicesoft Disclosure Letter, then Servicesoft shall notify
     Broadbase in writing of such exercise, conversion or exchange prior to
     issuing or delivering any shares of Servicesoft Capital Stock upon such
     exercise or conversion, and, if requested by Broadbase, shall not deliver
     any such shares of Servicesoft Capital Stock until the holder of the
     warrant being exercised, or the security being converted or exchange, has
     confirmed to Servicesoft and Broadbase its concurrence with the number set
     forth or reflected in the Servicesoft Disclosure Letter.

     7. Broadbase Pre-closing Covenants

     During the period from the date of this Agreement until the Effective Time,
Broadbase covenants to and agrees with Servicesoft (and, where Servicesoft
explicitly agrees to perform certain actions pursuant to specific provisions in
this Article 7, Servicesoft covenants to and agrees with Broadbase) as follows:

          7.1  Advice of Changes. Broadbase will promptly advise Servicesoft in
     writing of: (i) the discovery by Broadbase of any event, condition, fact or
     circumstance occurring on or prior to the date of this Agreement that would
     render any representation or warranty by Broadbase contained in this
     Agreement untrue or inaccurate in any material respect; (ii) any event,
     condition, fact or

                                      A-40
<PAGE>   257

     circumstance occurring subsequent to the date of this Agreement that would
     render any representation or warranty by Broadbase contained in this
     Agreement, if made on or as of the date of such event or the Closing Date,
     untrue or inaccurate in any material respect; (iii) any breach of any
     covenant or obligation of Broadbase pursuant to this Agreement or any
     Ancillary Agreement; (iv) any event, condition, fact or circumstance that,
     to its knowledge, would cause the Merger not to qualify as a tax-free
     reorganization in accordance with the provisions of Section 368(a)(1)(A)
     and Section 368(a)(2)(E) of the Code; (v) any event, condition, fact or
     circumstance that may make the timely satisfaction of any of the conditions
     set forth in Article 9 impossible or unlikely; and (v) any Material Adverse
     Effect on Broadbase.

          7.2  Conduct of Business. During the period from the date of this
     Agreement and continuing until the earlier of the termination of this
     Agreement pursuant to its terms or the Effective Time, Broadbase and each
     of its subsidiaries shall, except to the extent that Servicesoft shall
     otherwise consent in writing, carry on its business in the usual, regular
     and ordinary course, in substantially the same manner as heretofore
     conducted and in compliance in all material respects with all applicable
     laws and regulations, pay its debts and Taxes when due subject to good
     faith disputes over such debts or Taxes, pay or perform other material
     obligations when due, and use all reasonable efforts consistent with past
     practices and policies to (i) preserve intact its present business
     organization, (ii) keep available the services of its present officers,
     (iii) preserve its relationships with customers and licensees, (iv)
     maintain its equipment and other assets in good working condition and
     repair according to the standards it has maintained to the date of this
     Agreement, subject only to ordinary wear and tear, and (v) keep in full
     force all of its insurance policies and obtain any additional insurance
     required consistent with past practices for its business and property. In
     addition, during that period, Broadbase will promptly notify Servicesoft of
     any material event involving its business or operations consistent with the
     agreements contained herein, subject to any obligations of confidentiality.

          In addition, except as provided otherwise herein or as approved or
     recommended by Servicesoft, Broadbase will not, without the prior written
     consent of an executive officer of Servicesoft, which consent shall not be
     unreasonably withheld or delayed:

             (a) acquire or agree to acquire by merging or consolidating with,
        or by purchasing any equity interest in or a portion of the assets of,
        or by any other manner, any business or any corporation, partnership,
        association or other business organization or division thereof, in each
        case which involve the issuance of equity securities, or securities
        convertible into or exchangeable for equity securities, which in the
        aggregate represent more than 4,789,769 shares of common stock; provided
        that the pending acquisitions of Panopticon, Inc. and Decisionism, Inc.
        by Broadbase shall not be restricted by this Section 7.2;

             (b) issue or sell any shares of its capital stock of any class or
        any other of its securities, or issue, grant or create any warrants,
        obligations, subscriptions, options, convertible securities, stock
        appreciation rights or other commitments to issue shares of capital
        stock other than (i) in connection with permitted acquisitions of the
        type described in Section 7.2(a) and in the acquisitions of Panopticon,
        Inc. and Decisionism, Inc., (ii) upon exercise of outstanding options or
        warrants, or (iii) option grants not to exceed 800,000 shares of
        Broadbase Common Stock in the aggregate issuable thereunder, to
        employees, consultants and directors of Broadbase in the ordinary
        course, consistent with past practice plus options issuable (or which
        may be assumed) in connection with the acquisitions of Panopticon, Inc.
        and Decisionism, Inc.;

             (c) sell, lease, license, encumber or otherwise dispose of any
        properties or assets which are material, individually or in the
        aggregate, to the business of Broadbase, other than non-exclusive
        licenses of Broadbase IP in the ordinary course of business;

             (d) amend or cause or permit any amendment of its certificate of
        incorporation, bylaws or any other charter document, other than the
        amendment of Broadbase's certificate of incorporation to authorize
        additional shares of Broadbase common stock to be issued to Servicesoft
        Stockholders pursuant to the Merger;

                                      A-41
<PAGE>   258

             (e) declare, set aside or pay any cash or stock dividend or other
        distribution in respect of capital stock, or redeem or otherwise acquire
        any of its capital stock;

             (f) materially revalue any of its assets or, except as required by
        GAAP, make any change in accounting methods, principles or practices;

             (g) Consummate, or enter into any agreement to consummate, or hold
        any stockholders' meeting to consider and approve, any Broadbase
        Acquisition (as defined below), unless the record date for the meeting
        of Broadbase stockholders to approve such Broadbase Acquisition is (or
        will be) after the Effective Time. Notwithstanding anything in this
        Agreement to the contrary, Broadbase may enter into an agreement with a
        third party regarding a Broadbase Acquisition as long as the record date
        for a Broadbase stockholders' meeting to consider such Acquisition
        Proposal for Broadbase falls on a date after the Effective Time. As used
        herein, "Broadbase Acquisition" shall mean an Acquisition of Broadbase.

             (h) take any action that Broadbase knows will cause the Merger to
        fail to qualify as a tax-free reorganization.

             (i) agree to do, or permit a Subsidiary to do or agree to do, any
        of the things described in the preceding clauses 7.2(a) through (h).

          7.3  Regulatory Approvals. Broadbase will execute and file, or join in
     the execution and filing of, any application or other document that may be
     necessary in order to obtain the authorization, approval or consent of any
     governmental body, federal, state, local or foreign, which may be
     reasonably required, or which Servicesoft may reasonably request, in
     connection with the consummation of the transactions provided for in this
     Agreement including, without limitation, the Form S-4 and any applicable
     filings under the HSR Act. Broadbase will use all reasonable efforts to
     obtain all such authorizations, approvals and consents.

          7.4  Amendment of Certificate of Incorporation. Broadbase will amend
     its certificate of incorporation to authorize additional shares of
     Broadbase Common Stock to be issued to Servicesoft Stockholders.

          7.5  Broadbase Stockholders' Approval. Broadbase will call a special
     meeting of its stockholders, to be held within forty (40) days after the
     Form S-4 shall have been declared effective by the SEC (the "Broadbase
     Stockholders' Meeting"). Broadbase will solicit from its stockholders
     proxies in favor of the approval of the issuance of the Exchange Shares
     pursuant to the Merger, an amendment to Broadbase's Certificate of
     Incorporation to increase the authorized number of shares of Broadbase
     Common Stock in order to permit the issuance of Exchange Shares pursuant to
     the Merger, and any related matters and, to the extent required by
     applicable law or by Broadbase's certificate of incorporation or bylaws, in
     favor of the approval of this Agreement and the Merger (such approvals, the
     "Broadbase Stockholder Approvals"). Broadbase will use all reasonable
     efforts to take all other action necessary or advisable to secure the vote
     of its stockholders required under Delaware Law to obtain the Broadbase
     Stockholder Approvals. Subject to the following sentence, (i) the Board of
     Directors of Broadbase shall unanimously recommend that the stockholders of
     Broadbase give the Broadbase Stockholder Approvals; (ii) the Form S-4 and
     the Prospectus/Proxy Statement will include a statement to the effect that
     Broadbase's Board of Directors has recommended that the stockholders of
     Broadbase vote in favor of the Broadbase Stockholder Approvals; and (iii)
     neither the Board of Directors of Broadbase nor any committee thereof shall
     withdraw, amend or modify, or propose or resolve to withdraw, amend or
     modify in a manner adverse to Servicesoft, the recommendation of the Board
     of Directors of Broadbase that the stockholders of Broadbase vote in favor
     of the Broadbase Stockholder Approvals. Notwithstanding the foregoing,
     nothing in this Agreement shall prevent the Board of Directors of Broadbase
     from withholding, withdrawing, amending or modifying its recommendation in
     favor of the Broadbase Stockholder Approvals if (i) an unsolicited bona
     fide offer made by a third party to consummate a Broadbase Acquisition
     (including, without limitation, the acquisition by any person or group,
     including by way of tender offer or an

                                      A-42
<PAGE>   259

     exchange offer or a two step transaction involving a tender offer followed
     with reasonable promptness by a merger involving Broadbase, directly or
     indirectly, of ownership of 100% of the then outstanding shares of capital
     stock of Broadbase) in which, such third party has required as a condition
     to closing such transaction, that this Agreement shall have been terminated
     and the Merger not effected (a "Broadbase Acquisition Offer") is made to
     Broadbase and is not withdrawn, (ii) Broadbase shall have provided written
     notice to Servicesoft advising Servicesoft that Broadbase has received a
     Broadbase Acquisition Offer, specifying all of the material terms and
     conditions of such Broadbase Acquisition Offer and identifying the person
     or entity making such Broadbase Acquisition Offer and (iii) the Board of
     Directors of Broadbase concludes in good faith, after consultation with its
     outside legal counsel and a financial advisor of national standing, that,
     in light of such Broadbase Acquisition Offer, the withholding, withdrawal,
     amendment or modification of its recommendation that the stockholders of
     Broadbase give the Broadbase Stockholder Approvals is required in order for
     the Board of Directors of Broadbase to comply with its fiduciary
     obligations to Broadbase's stockholders under applicable law. The Broadbase
     Stockholders' Meeting will be called, held and conducted, and any proxies
     will be solicited, in compliance with applicable law. Broadbase's
     obligation to call, give notice of, convene, hold and conduct the Broadbase
     Stockholders' Meeting shall not be limited or otherwise affected by the
     commencement, disclosure, announcement or submission to the stockholders of
     Broadbase of a Broadbase Acquisition Offer, or by any withdrawal, amendment
     or modification of the recommendation of the Board of Directors of
     Broadbase at such Broadbase Stockholders' Meeting. Broadbase may not hold a
     meeting of its stockholders to consider a Broadbase Acquisition unless the
     record date for such meeting is after the Effective Time.

          7.6  Litigation. Broadbase will notify Servicesoft in writing promptly
     after learning of any action, suit, proceeding, claim, arbitration or
     investigation threatened or pending for the purpose or with the probable
     effect of enjoining or preventing the consummation of any of the
     transactions contemplated by this Agreement, or which would be reasonably
     expected to have a Material Adverse Effect on Broadbase.

          7.7  Certain Employee Benefits. As soon as practicable after the
     execution of this Agreement, Servicesoft and Broadbase shall confer and
     work together in good faith to agree upon mutually acceptable employee
     benefit and compensation arrangements for Servicesoft employees following
     the Merger. Broadbase's benefit arrangements and employee plans shall, to
     the extent that this provision does not violate the applicable plan,
     policy, program or arrangement, give full credit (including, without
     limitation, for purposes of eligibility, vesting and benefits accrued) for
     each participant's service to Servicesoft for all purposes for which such
     service was recognized under Servicesoft's benefit arrangements or employee
     plans prior to the effective time.

          7.8  Satisfaction of Conditions Precedent. Broadbase will use all
     reasonable efforts to satisfy or cause to be satisfied all the conditions
     precedent which are set forth in Article 9 on or before the Closing Date.
     Broadbase will use all reasonable efforts to cause the transactions
     provided for in this Agreement to be consummated, and, without limiting the
     generality of the foregoing, to obtain all consents and authorizations of
     third parties and to make all filings with, and give all notices to, third
     parties that may be necessary or reasonably required on its part in order
     to effect the transactions provided for herein.

          7.9  Blue Sky Laws. Broadbase shall take such steps as may be
     necessary to comply with the securities and Blue Sky laws of all
     jurisdictions which are applicable in connection with the Merger.

          7.10  Nasdaq Listing. Broadbase agrees to authorize for listing on the
     Nasdaq Stock Market the shares of Broadbase Common Stock issuable, and
     those required to be reserved for issuance, in connection with the Merger,
     upon official notice of issuance.

          7.11  Board Representation. Broadbase shall appoint the chief
     executive officer of Servicesoft and Robert Davoli (or such other person as
     may be designated by the mutual agreement of Broadbase and Servicesoft) to
     Broadbase's Board of Directors as of the Effective Time; provided however,
     that if upon such appointment and any concurrent resignations of any
     present Broadbase directors, the Board

                                      A-43
<PAGE>   260

     of Directors of Broadbase shall consist of seven (7) or more members, then
     Broadbase shall appoint one additional person (who shall be mutually
     acceptable to Servicesoft and Broadbase) to the Board of Directors of
     Broadbase.

          7.12  Bridge Loan.

          (a) Provided this Agreement has not been terminated as provided in
     Article 11, Broadbase agrees to advance to Servicesoft, on an
     as-needed-basis, bridge loans of up to an aggregate of $15 million (the
     "Loans") for the purpose of financing operating expenses incurred in the
     ordinary course of business, pursuant to the terms set forth in the form of
     convertible promissory note attached hereto as Exhibit D, and subject to
     execution and delivery of such note by Servicesoft. Each advance of all or
     any portion of the Loan shall be subject to the conditions that (i) the
     representations and warranties of Servicesoft set forth in this Agreement
     shall be true and correct in all material respects as of the time of such
     advance, (ii) Servicesoft shall not have breached in any material respect
     any covenant contained in this Agreement, and (iii) Servicesoft shall have
     given Broadbase at least five (5) days' written notice requesting such
     advance and affirming that the conditions described in clauses (i) and (ii)
     have been satisfied.

          (b) If this Agreement is terminated pursuant to Article 11, then all
     unpaid principal and accrued interest under the Loan (at the rate of 8.5%
     per annum) shall become due and payable by Servicesoft on the date that is
     one year after the date of such termination (the "Due Date"); provided;
     however, that Broadbase shall be entitled to require earlier repayment
     either upon (i) the closing of any equity financing following such
     termination, in which case, Broadbase shall be entitled to receive the
     lesser of (1) the aggregate amount of the unpaid principal and accrued
     interest under the Loan and (2) 50% of the funds raised in such equity
     financing, in either case, in payment for the unpaid principal and accrued
     interest under the Loan, with the remainder to be paid off in full on the
     Due Date, or (ii) an Acquisition of Servicesoft. Servicesoft agrees to
     provide Broadbase with at least ten days' prior written notice of the
     closing of Servicesoft's next equity financing and of any Acquisition of
     Servicesoft, including the terms thereof. At the election of Broadbase, the
     Loans may at any time be converted into shares of Servicesoft common stock
     at $10 per share or into the same securities as are issued in the next
     equity financing following such termination at a conversion price equal to
     the price per share of the equity securities sold in such equity financing,
     and each party hereto will take all steps necessary or advisable to effect
     such result.

          7.13  Section 16. Provided that Servicesoft delivers to Broadbase the
     Section 16 Information (as defined below) in a timely fashion, the Board of
     Directors of Broadbase, or a committee of two or more Non-Employee
     Directors thereof (as such term is defined for purposes of Rule 16b-3 under
     the Exchange Act), shall adopt resolutions prior to the consummation of the
     Merger, providing that the receipt by the Company Insiders (as defined
     below) of Broadbase Common Stock upon conversion of the Servicesoft Common
     Stock, and of options for Broadbase Common Stock upon conversion of the
     Servicesoft Options, in each case pursuant to the transactions contemplated
     hereby and to the extent such securities are listed in the Section 16
     Information, are intended to be exempt from liability pursuant to Section
     16(b) under the Exchange Act. Such resolutions shall comply with the
     approval conditions of Rule 16b-3 under the Exchange Act for purposes of
     such Section 16(b) exemption, including, but not limited to, specifying the
     name of the Company Insiders, the number of securities to be acquired or
     disposed of for each such person, the material terms of any derivative
     securities, and that the approval is intended to make the receipt of such
     securities exempt pursuant to Rule 13b-3(d). "Section 16 Information" shall
     mean information regarding the Company Insiders, the number of shares of
     Servicesoft capital stock held by each such Company Insider and expected to
     be exchanged for Broadbase Common Stock in connection with the Merger, and
     the number and description of the Servicesoft Options held by each such
     Company Insider and expected to be converted into options for Broadbase
     Common Stock in connection with the Merger. "Company Insiders" shall mean
     those officers and directors of Servicesoft who will be subject to the
     reporting requirement of Section 16(b) of the Exchange Act with respect to
     Broadbase and who are listed in the Section 16 Information.

          7.14  Access to Information. Until the Closing Date and subject to the
     terms and conditions hereof relating to the confidentiality and use of
     confidential and proprietary information, Broadbase will provide
     Servicesoft and its agents with reasonable access, during regular business
     hours, to the files, books, records and offices of Broadbase and its
     subsidiaries, including, without limitation, any and all information
     relating to Broadbase's taxes, commitments, Contracts, leases, licenses,
     real, personal and intangible property, and financial condition; provided
     that Broadbase shall not be required to provide Servicesoft or its agents
     with access to any files, books, records or information where (a) such
     access would waive any privileges available under applicable law, or (b)
     would violate the terms of any nondisclosure agreement with any third party
     after Broadbase shall have used all reasonable efforts to obtain a waiver
     of, or consent to disclosure under, such agreement.

          7.15  Necessary Consents. Broadbase will use all reasonable efforts to
     obtain such written consents and take such other actions as may be
     necessary or appropriate for Broadbase, in addition to those set forth in
     Section 7.5, to allow the consummation of the transactions provided for
     herein.

          7.16  Director and Officer Indemnification. From and after the
     Effective Time, Broadbase shall cause the certificate of incorporation and
     by-laws of the Surviving Corporation to include indemnification provisions
     substantially identical in all material respects to the corresponding
     existing provisions in the certificate of incorporation and by-laws of
     Servicesoft.

          7.17  No Solicitation. From and after the date of this Agreement until
     the Effective Time or termination of this Agreement pursuant to Article 11,
     Broadbase and its Subsidiaries will not, nor will they authorize or permit
     any of their respective officers, directors, affiliates or employees or any
     investment banker, attorney or other advisor or representative retained by
     any of them to, directly or indirectly solicit or initiate the making,
     submission or announcement of any Acquisition with respect to Broadbase.
     Without limiting the foregoing, it is understood that any violation of the
     restrictions set forth in the preceding sentence by any officer, director
     or employee of Broadbase or any of its Subsidiaries or any investment
     banker, attorney or other advisor or representative of Broadbase or any of
     its Subsidiaries shall be deemed to be a breach of this Section 7.17 by
     Broadbase; provided that if such violation consists of a communication by
     any such advisor which was unauthorized by Broadbase and Broadbase
     terminates its relationship with such advisor and with such advisor's
     employer, or terminates the employment of such employee, immediately upon
     becoming aware of such communication, then from and after such termination,
     such communication shall no longer be deemed to constitute a material
     breach of this Agreement for purposes of Sections 9.2 and 11.1(a)(ii).

     Servicesoft, Broadbase shall enter into such amendments of this Agreement
     as may be necessary to allow the holders of Servicesoft Canada Common to

     for both Servicesoft and Broadbase reach agreement on the structure of any
     amendment required to the constituent documents of Servicesoft Canada;
     provided that any such amendment and any such deferred exchange of shares
     of Servicesoft Canada Common stock for Exchange Shares: (i) provides for
     the issuance of Exchange Shares to the holders of Servicesoft Canada common
     stock upon their exchange on the same basis as if they had exchanged at or
     before the Effective Time of the Merger, including the retention of ten
     percent (10%) of such Exchange Shares in escrow; (ii) would not involve any
     adverse tax consequences for such holders or for Servicesoft, Servicesoft
     Canada or Broadbase, (iii) provides that the Exchange Shares to be issued

     on the Form S-4 (or other applicable form) to be filed with the SEC in
     connection with the registration of the other Exchange Shares, (iv) would
     not require the issuance or creation of any new class of preferred stock of
     Broadbase, or other amendments to Broadbase's charter documents, (v) would
     not involve any adverse accounting consequences for Broadbase, and (vi) be
     reasonably practicable to implement.

certificate and a bond in form and amount reasonably satisfactory to Broadbase
or the Exchange Agent (a "Bond"), (2) will execute and deliver an

<PAGE>   263

Agent to issue to such surrendering holder certificate(s) the number of Exchange
Shares to which such holder is entitled pursuant to Section 2.1, less the Escrow
Shares to be deposited into escrow on behalf of such holder pursuant to Section
2.2, and will distribute any cash payable under Section 2.1(a)(vi); provided
that if the information set forth in the Servicesoft Stockholder Representations
is inconsistent with the information set forth in the Servicesoft Disclosure
Letter, then Broadbase shall be entitled to condition such issuance upon its
confirmation, to its reasonable satisfaction, that such difference will not have
any material adverse consequences to Broadbase or require the issuance of a
greater number of Exchange Shares than would have been required had such
information been consistent.

     (ii) At the Effective Time, the stock transfer books of Servicesoft will be
closed and no transfer of shares of Servicesoft capital stock will thereafter be
made. If, after the Effective Time, Servicesoft Certificates are presented for
any reason, they will be canceled and exchanged as provided in this Section 8.2;
provided, however, that subject to applicable law any Servicesoft Certificate
that is not properly submitted to Broadbase for exchange and cancellation within
three years after the Effective Time shall no longer evidence ownership of or
any right to receive shares of Broadbase common stock and all rights of the
holder of such Servicesoft Certificate, with respect to the shares previously
evidenced by such Servicesoft Certificate, shall cease.

     (iii) Subject to the provisions of Section 2.2 and the Escrow Agreement
with respect to the Escrow Shares, all Exchange Shares delivered upon the
surrender of Servicesoft Certificates in accordance with the terms hereof will
be deemed to have been delivered in full satisfaction of all rights pertaining
to the Servicesoft common stock evidenced by such Servicesoft Certificates.

     (b) Unexchanged Shares. Until Servicesoft Certificates outstanding prior to
the Merger (or affidavits of lost (or non-issued) certificates and attendant
Bonds) are surrendered pursuant to Section 8.2(a), such Servicesoft Certificates
will be deemed, for all purposes, to evidence ownership of (i) the number of
Exchange Shares into which the Servicesoft common stock will have been converted
(less the number of shares to be withheld as Escrow Shares pursuant to Section
2.2) and (ii) if applicable, cash in lieu of fractional shares.

     (c) Payment of Dividends. No dividends or distributions payable to holders
of record of Broadbase common stock after the Effective Time, or cash payable in
lieu of fractional shares, will be paid to holders of any unsurrendered
Servicesoft Certificates until such holders surrender their Servicesoft
Certificates (or affidavits of lost (or non-issued) certificates and attendant
Bonds). Upon such surrender, subject to the effect, if any, of applicable
escheat and other laws, there will be delivered to such tendering holder the
amount of any dividends and distributions paid with respect to Exchange Shares
so withheld as of any date subsequent to the Effective Time and prior to such
date of delivery, less any non-cash dividends and distributions paid with
respect to the Escrow Shares (which shall be held until the Escrow Shares are
released as and to the extent provided in the Escrow Agreement).

     (d) Miscellaneous.

     (i) If any certificates for Exchange Shares are to be issued in a name
other than that in which the Servicesoft Certificate surrendered in exchange
therefor is registered, the following shall be conditions of such exchange: (A)
the Servicesoft Certificate must be properly endorsed and otherwise in proper
form for transfer, and (B) the person requesting such exchange shall either pay
to the Exchange Agent any transfer or other taxes required by reason of the
issuance of certificates for such Exchange Shares in a name other than that of
the registered holder of the Servicesoft Certificate surrendered or establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
applicable.

     (ii) Notwithstanding anything in this Agreement to the contrary, neither
the Exchange Agent nor any party hereto shall be liable to a Servicesoft
Stockholder for any Exchange Shares or dividends thereon or the cash payments
otherwise due hereunder delivered to a public official pursuant to applicable
abandoned property, escheat or other similar laws following the passage of time
specified therein.

     8.3  Dissenting Shares. Notwithstanding anything to the contrary in this
Agreement:

          (a) No Dissenting Shares will be converted into or represent a right
     to receive the consideration described in Section 2.1(a)(i). Instead, each
     holder of Dissenting Shares will be entitled only to such rights as are
     granted by Delaware Law for Dissenting Shares. The Exchange Shares to which
     such dissenting Servicesoft Stockholders would have been entitled had each
     assented to the merger, will have the status of authorized and unissued
     shares of Broadbase.

          (b) For each Servicesoft Stockholder who complies with all
     requirements for obtaining stockholders' rights of appraisal with respect
     to such shares, but subsequently loses (through the failure to perfect or
     otherwise) or effectively withdraws such demand for such rights of
     appraisal in accordance with Delaware Law, such holder's shares shall, as
     of the Effective Time (or, if after the Effective Time, upon the occurrence
     of such event) automatically be converted into and represent only the right
     to receive the consideration described in Section 2.1 upon surrender of the
     applicable certificate(s) as provided in Section 8.2.

          (c) Servicesoft shall comply with the notice and other procedural
     requirements set forth in Section 262 of Delaware Law with respect to any
     Servicesoft Stockholder that properly demands stockholders' rights of
     appraisal for such Servicesoft shares and that has not lost or effectively
     withdrawn such demand for such rights of appraisal rights. Broadbase shall
     have the opportunity to participate in all negotiations and proceedings
     with respect to such demands. Servicesoft shall not, except with the prior
     written consent of Broadbase, voluntarily make any payment with respect to
     any demands for the exercise of appraisal rights or offer to settle or
     settle any such demands.

     8.4  Employee Plans. As of the Effective Time, Broadbase and Servicesoft
shall take such actions as are necessary to effect the mutually acceptable
employee benefit and compensation arrangements as determined pursuant to Section
6.12.

prior to the Effective Time, whether before or after approval by the Servicesoft
Stockholders:

          (i) by the mutual written consent of Servicesoft and Broadbase;

          (ii) by either Servicesoft or Broadbase, if such party (including its
     stockholders) is not in material breach of any representation, warranty,
     covenant or agreement contained in this Agreement, and such other party is
     in material breach of any representation, warranty, covenant or agreement
     contained in this Agreement, or if any representation of such other party
     will have become untrue, in either case to an extent that would cause the
     conditions set forth in Article 9 (for Servicesoft) or Article 10 (for
     Broadbase) not to be satisfied and such breaching party fails to cure such
     material breach within 15 days of written notice of such material breach
     from the non-breaching party (except that no cure period will be provided
     for a breach which by its nature cannot be cured);

          (iii) by either Servicesoft or Broadbase, if the Merger shall not have
     been consummated by February 28, 2001 for any reason; provided, however,
     that the right to terminate this Agreement under this Section 11(a)(iii)
     shall not be available to any party whose action or failure to act has been
     a principal cause of or resulted in the failure of the Merger to occur on
     or before such date and such action or failure to act constitutes a breach
     of this Agreement;

          (iv) by either Servicesoft or Broadbase, if there is a final
     nonappealable order of a federal or state court in effect preventing
     consummation of the Merger, or if any statute, rule, regulation or order is
     enacted, promulgated or issued or deemed applicable to the Merger by any
     governmental body that would make consummation of the Merger illegal;

          (v) by either Servicesoft or Broadbase if the required approval of the
     Servicesoft Stockholders contemplated by this Agreement shall not have been
     obtained by reason of the failure to obtain the required vote by written
     consent or at a meeting of the Servicesoft Stockholders duly convened
     therefore or at any adjournment thereof; provided, however, that the right
     to terminate this Agreement under this 11.1(a)(v) shall not be available to
     Servicesoft where the failure to obtain the Servicesoft Stockholder
     approval shall have been caused by the action or failure to act of
     Servicesoft (or an officer or director of Servicesoft) and such action or
     failure to act constitutes a material breach of this Agreement;

          (vi) by either Servicesoft or Broadbase, if the required approval of
     Broadbase Stockholders contemplated by this Agreement shall not have been
     obtained by reason of the failure to obtain the required votes at a meeting
     of Broadbase stockholders duly convened therefore or at any adjournment
     thereof; provided, however, that the right to terminate this Agreement

     shall not be available to Broadbase where the failure to obtain the
     Broadbase stockholder approvals shall have been caused by the action or
     failure to act of Broadbase and such action or failure to act constitutes a
     material breach by Broadbase of this Agreement;

     11.2  Termination Procedures. If either party wishes to terminate this
Agreement pursuant to Section 11.1, such party shall deliver to the other party
a written notice stating that such party is terminating this Agreement and
setting forth a brief description of the basis of such termination. Termination
of this Agreement will be effective upon the delivery of such notice.

     11.3  Continuing Obligations. In the event of the termination of this
Agreement as provided in Section 11.1, this Agreement shall be of no further
force or effect, except (i) as set forth in Section 7.12(b), this Section 11.3,
Section 11.4 and Article 12, each of which shall survive the termination of this
Agreement, and (ii) nothing herein shall relieve any party from liability for
any willful breach of this Agreement. No termination of this Agreement shall
affect the obligations of the parties pursuant to any agreement to maintain the
confidentiality of information regarding the other party, all of which
obligations shall survive termination of this Agreement in accordance with their
terms.

     11.4  Termination Fee.

     (a) In the event that this Agreement is terminated (x) by Broadbase under
Section 11.1(a)(ii) or (y) by either Broadbase or Servicesoft under Section
11.1(a)(v), Servicesoft shall promptly, but in no event later than two days
after the date of such termination, pay Broadbase a fee equal to $12.5 million
in immediately available funds (the "Servicesoft Termination Fee"); provided,
however, that in the case of termination pursuant to Section 11.1(a)(ii), such
payment shall be made only if (1) following the date of this Agreement and prior
to the termination of this Agreement, a person has publicly announced an
Acquisition Proposal and (2) within nine months following the termination of
this Agreement, either an Acquisition Transaction is consummated, or Servicesoft
enters into an agreement providing for an Acquisition Transaction, in which case
such termination fee shall be paid within two days of the consummation of such
Acquisition Transaction.

     (b) In the event that this Agreement is terminated by Servicesoft under
Section 11.1(a)(ii) or by either Broadbase or Servicesoft under Section
11.1(a)(vi), Broadbase shall promptly, but in no event later than two days after
the date of such termination, pay Servicesoft a fee equal to $12.5 million in
immediately available funds (the "Broadbase Termination Fee"); provided,
however, that in the case of termination pursuant to Section 11.1(a)(ii), such
payment shall be made only if (1) following the date of this Agreement and prior
to the termination of this Agreement, a person has publicly announced an
Acquisition Proposal and (2) within nine months following the termination of
this Agreement, either an Acquisition Transaction is consummated, or Broadbase
enters into an agreement providing for an Acquisition Transaction. If any
principal or interest under any of the Loans contemplated by Section 7.12 remain
outstanding, then the Broadbase Termination Fee payable by Broadbase pursuant to
this Section 11.4(b) shall be reduced by the amount of the outstanding Loans
owed by Servicesoft. In addition, in the event that (1) this Agreement is
terminated by Broadbase or Servicesoft under Section 11.1(a)(vi) and (2) either
(x) the Form S-4 and the Prospectus/Proxy Statement did not include, pursuant to
Section 7.5 of this Agreement, a statement to the effect that Broadbase's Board
of Directors has recommended that Broadbase Stockholders vote in favor of the
Broadbase Stockholder Approvals or (y) the Board of Directors of Broadbase (or a
committee thereof) shall have withdrawn, amended or modified, in a manner
adverse to Servicesoft, the recommendation of the Board of Directors of
Broadbase that the stockholders of Broadbase vote in favor of the Broadbase
Stockholder Proposals, then the outstanding principal of, and accrued interest
on, the Loans shall be immediately deemed to have been repaid in full and all
remaining amounts available with respect to the Loans shall be paid to
Servicesoft at such time as the payment of the Broadbase termination fee,
without any recourse to, or further obligation on the part of, Servicesoft.

     (c) Each party hereto acknowledges that the agreements contained in this
Section 11.4 are an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, the other party would not enter
into this Agreement. Accordingly, if any party hereto fails to pay in a timely

                                      A-52
<PAGE>   269

manner the amounts due pursuant to this Section 11.4, and, in order to obtain
such payment, the other party makes a claim that results in a judgment against
the breaching party for the amounts set forth in this Section 11.4, the
breaching party shall pay to the other party such other party's reasonable costs
and expenses (including reasonable attorneys' fees and expenses) in connection
with such suit, together with interest on the amounts set forth in this Section
11.4 at the prime rate of The Chase Manhattan Bank in effect on the date such
payment was required to be made. Absent a willful breach of this Agreement, any
Servicesoft Termination Fee or Broadbase Termination Fee paid pursuant to this
Section 11.4 shall be the sole liability of the paying party.

     12.  Survival of Representations, Indemnification and Remedies, Continuing
Covenants

     12.1  Survival of Representations. All representations, warranties,
covenants and agreements of Broadbase and Servicesoft contained in this
Agreement will remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the parties to this Agreement, until the
earlier of the termination of this Agreement and the expiration of the Escrow
Period, whereupon such representations, warranties, covenants and agreements
will expire.

     12.2  Agreement to Indemnify. Subject to the limitations set forth in this
Article 12, the Servicesoft Stockholders will severally indemnify and hold
harmless Broadbase and its officers, directors, agents and employees, and each
person, if any, who controls or may control Broadbase within the meaning of the
Securities Act (hereinafter referred to individually as an "Indemnified Person"
and collectively as "Indemnified Persons") from and against any and all claims,
demands, actions, causes of actions, losses, costs, damages, liabilities and
expenses, including without limitation, reasonable legal fees and costs
(hereinafter referred to as "Damages") directly or indirectly arising out of or
resulting from:

          (a) any misrepresentation or breach of or default in connection with
     any of the representations, warranties, agreements and covenants given or
     made by Servicesoft in this Agreement or any certificate, document or
     instrument delivered by or on behalf of Servicesoft pursuant hereto;

          (b) any Excess Expenses; or

          (c) any failure of each Servicesoft Stockholder to have good, valid
     and marketable title to the issued and outstanding Servicesoft Capital
     Stock identified in Schedule 1 to such Servicesoft Stockholder's Letter of
     Transmittal, free and clear of all liens, claims, pledges, options, adverse
     claims, assessments or charges of any nature whatsoever ("Ownership
     Losses");

provided, however, that for purposes of the foregoing clause (c), the
Indemnified Person may only seek and recover Damages from the Servicesoft
Stockholder who failed to have good, valid and marketable title to such shares
of Servicesoft Capital Stock free and clear of all liens, claims, pledges,
options, adverse claims, assessments or charges.

     12.3  Limitations on Liability; Exceptions.

     (a) Limitations on Liability. Subject to Section 12.3(c), the Escrow Shares
and any other assets deposited in escrow pursuant to the Escrow Agreement shall
be the Indemnified Persons' sole recourse against the Servicesoft Stockholders
under this Agreement, and no claim for Damages shall first be made under Section
12.2 after expiration of the Escrow Period. Except as set forth in Section
12.3(c), the remedies set forth in this Article 12 shall be the exclusive
remedies of Broadbase and the other Indemnified Persons against any Servicesoft
Stockholder under any theory or liability.

     (b) Threshold. Except for indemnification with respect to Excess Expenses,
the indemnification provided for in this Article 12 shall not apply unless and
until the aggregate Damages for which one or more Indemnified Persons seeks
indemnification exceeds $1,000,000, in which event the indemnification provided
for in this Article 12 will include the aggregate of all Damages; provided,
however, that this Section 12.3(b) shall not apply to liability or
indemnification obligations of the Servicesoft Stockholders with respect to any
matter or claim described in Section 12.2(b).

                                      A-53
<PAGE>   270

     (c) Exceptions to Limitations on Liability. None of the limitations set
forth in Sections 12.3(a) or 12.3(b) shall in any manner limit the liability or
indemnification obligations of the Servicesoft Stockholders with respect to: (i)
intentional fraud; or (ii) any Ownership Losses. Notwithstanding the foregoing,
in no event shall any Servicesoft Stockholder be liable for any amounts in
excess of the value of the aggregate consideration received by such Servicesoft
Stockholder in connection with the Merger (determined as set forth in Section
4.5 of the Escrow Agreement); provided, however, that such limitation shall not
apply to Damages resulting from intentional fraud by such Servicesoft
Stockholder. In the event of intentional fraud, the Indemnified Persons agree
that they shall seek indemnification against the Escrow Shares pro rata pursuant
to the terms of the Escrow Agreement then available under the Escrow Agreement
and shall only be entitled to receive indemnification for such claims directly
from the Servicesoft Stockholders if all of the Escrow Shares have been released
pursuant to the terms of the Escrow Agreement.

     12.4  Survival of Claims. Notwithstanding anything herein to the contrary,
if, prior to the expiration of the Escrow Period, an Indemnified Person makes a
claim for indemnification under either this Agreement or the Escrow Agreement
with respect to a misrepresentation or breach of such representation, warranty
or covenant, then the Indemnified Person's rights to indemnification under this
Article 12 for such claim shall survive the expiration of the Escrow Period. In
addition, notwithstanding anything herein to the contrary, the obligation of
each Servicesoft Stockholder to indemnify the Indemnified Persons for any
Damages resulting directly or indirectly from the failure of such Servicesoft
Stockholders to have good, valid and marketable title to the issued and
outstanding Servicesoft Capital Stock identified in Schedule 1 to such
Servicesoft Stockholder's Letter of Transmittal, free and clear of all liens,
claims, pledges, options, adverse claims, assessments or charges of any nature
whatsoever shall continue in effect for the duration of the applicable statute
of limitations.

     12.5  No Indemnity for Corporate Agents. Each of the indemnifying
Servicesoft Stockholders agrees that such Servicesoft Stockholder will not make
any claim for indemnification against Servicesoft by reason of the fact that
such indemnifying stockholder was a director, officer, employee or agent of any
such entity or was serving at the request of any such entity as a partner,
trustee, director, officer, employee or agent of another entity (whether such
claims is for judgments, damages, penalties, fines, costs, amounts paid in
settlement, losses, expense or otherwise and whether such claim is pursuant to
any statute, charter document, bylaw, agreement or otherwise) with respect to
any action, suit, proceeding, complaint, claim or demand brought by Broadbase
against the indemnifying stockholder pursuant to Section 12.2 or otherwise in
its capacity as a Servicesoft Stockholder (whether such action, suit,
proceeding, complaint, claim or demand is pursuant to this Agreement, applicable
law or otherwise).

     12.6  Servicesoft Stockholders' Representative.

     (a) Authority. The Servicesoft Stockholders, by their approval of the
Merger and/or their tender pursuant to Section 8.2 of Servicesoft Certificates,
will be conclusively deemed to have consented to, approved and agreed to be
personally bound by: (a) the indemnification provisions of Article 12, (b) the
Escrow Agreement, (c) the appointment of Mark Skapinker as the Representative of
the Servicesoft Stockholders under the Escrow Agreement and as the
attorney-in-fact and agent for and on behalf of the Servicesoft Stockholders
(including their successors and assigns) as provided in the Escrow Agreement and
(d) the taking by the Representative of any and all actions and the making of
any decisions required or permitted to be taken by the Representative under the
Escrow Agreement, including, without limitation, the exercise of the power to:
(i) authorize delivery to Broadbase of Escrow Shares in satisfaction of
indemnity claims by Broadbase or any other Indemnified Person (as defined
herein) pursuant to Article 12 and/or the Escrow Agreement; (ii) agree to,
negotiate, enter into settlements and compromises of, demand arbitration of, and
comply with orders of courts and awards of arbitrators with respect to, such
claims; (iii) arbitrate, resolve, settle or compromise any claim for indemnity
made pursuant to Article 12; (iv) waive any right of any or all of the
Servicesoft Stockholders following the Merger with respect to matters set forth
in this Agreement, the Escrow Agreement or any other agreement contemplated by
this Agreement; (v) give and receive all notices required to be given under this
Agreement and the Escrow Agreement; and (vi) take all actions necessary in the
sole judgment of the Representative for the

                                      A-54
<PAGE>   271

accomplishment of the foregoing. The Representative will have unlimited
authority and power to act on behalf of the Servicesoft Stockholders with
respect to the Escrow Agreement and the disposition, settlement or other
handling of all claims governed by the Escrow Agreement, and all rights or
obligations arising under the Escrow Agreement so long as all Servicesoft
Stockholders are treated in the same manner. The Representative is authorized to
take any actions deemed by him to be appropriate or reasonably necessary to
carry out the provisions of Article 12 hereof. In addition, the Representative
is authorized to accept service of process upon the Servicesoft Stockholders.
All decisions and actions of the Representative in connection with this
Agreement and the Escrow Agreement shall be binding and conclusive upon the
Servicesoft Stockholders, and Broadbase, the Surviving Corporation and the
Escrow Agent will be entitled to rely on any action or decision of the
Representative. The Representative will not be a trustee for any Servicesoft
Stockholder or have any fiduciary duty to any Servicesoft Stockholder, and in
performing the functions specified in this Agreement and the Escrow Agreement,
the Representative will not be liable to any Servicesoft Stockholders for any
act or omission the Representative made in good faith and in the exercise of
reasonable judgment. As provided in the Escrow Agreement, any out-of-pocket
costs and expenses reasonably incurred by the Representative in connection with
actions taken pursuant to the terms of the Escrow Agreement, at the
Representative's option, either (i) will be paid by the Servicesoft Stockholders
to the Representative or (ii) if shares are available for distribution to the
Servicesoft Stockholders pursuant to the Escrow Agreement, at the request of the
Representative, a portion of those shares will be sold by the Escrow Agent and
the proceeds paid to or at the direction of the Representative, in either case,
pro rata in proportion to the Servicesoft Stockholders' respective percentage
interests in the Escrow Shares.

     (b) Standard of Conduct. Neither the Representative nor any of his
partners, members, directors, officers, employees or agents shall be liable to
any of the Servicesoft Stockholders for any error of judgment, act done or
omitted by them, or mistake of fact or law in connection with his services
pursuant to Article 12, unless caused by his own gross negligence or willful
misconduct. In taking any action or refraining from taking any action whatsoever
the Representative shall be protected in relying upon any notice, paper or other
document reasonably believed by him to be genuine, or upon any evidence
reasonably deemed by him to be sufficient. The Representative shall not be
required to take any action which is contrary to this Agreement, the Escrow
Agreement or applicable law. The Representative may consult with counsel in
connection with his duties and shall be fully protected in any act taken,
suffered or permitted by them in good faith in accordance with the advice of
counsel. In connection with their services under Article 12, the Representative
shall not be responsible for determining or verifying the authority of any
person acting or purporting to act on behalf of any party to this Agreement.

     (c) Indemnification. Each Servicesoft Stockholder agrees to indemnify the
Representative, ratably in accordance with his or her pro rata share of the
Escrow Shares, for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may at any time be imposed on, incurred by or
asserted against the Representative in any way relating to or arising out of
this Agreement or any documents contemplated by or referred to herein or therein
or the transactions contemplated hereby or thereby or the enforcement of any of
the terms hereof or thereof or of any such other documents; provided, however,
that no Servicesoft Stockholder shall be liable for any of the foregoing to the
extent they arise from the Representative's gross negligence or willful
misconduct. The Representative shall be fully justified in refusing to take or
to continue to take any action hereunder unless he shall first be indemnified to
his reasonable satisfaction by the Servicesoft Stockholders against any and all
liability and expense which may be incurred by him by reason of taking or
continuing to take any such action.

     (d) Resignation or Removal of the Representative. Subject to the
appointment and acceptance of a successor Representative as provided below, the
Representative may (i) resign at any time thirty (30) days subsequent to giving
notice thereof to the Servicesoft Stockholders, and (ii) be removed at any time
with or without cause by action of the Servicesoft Stockholders who represented
a majority of the rights to the Escrow Shares. Upon any such resignation or
removal, holders of a majority of the Escrow Shares may appoint a successor
Representative, which successor shall be reasonably acceptable to

                                      A-55
<PAGE>   272

Broadbase. If no successor Representative shall have been appointed by the
Servicesoft Stockholders and accepted such appointment within twenty (20) days
after the retiring Representative's giving of notice of resignation or the
Servicesoft Stockholders' removal of the Representative, then the retiring or
removed Representative may, on behalf of the Servicesoft Stockholders, appoint a
successor, which shall be reasonably acceptable to Broadbase. Upon the
acceptance of any appointment as the Representative hereunder, such successor
Representative shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring or removed Representative, and the
retiring or removed Representative shall be discharged from his duties and
obligations hereunder. After any retiring Representative's resignation or
removal hereunder as the Representative, the provisions of Article 12 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as the Representative.

     (e) Representative as Servicesoft Stockholder. The Representative, to the
extent he is or was a Servicesoft Stockholder, shall have the same rights and
powers under this Agreement as any other Servicesoft Stockholder and may
exercise the same as though he were not serving as the Representative, and the
term "Servicesoft Stockholder" shall include the Representative in his capacity
as such.

     13.  Miscellaneous

     13.1  Entire Agreement. The Letter Agreement between Servicesoft and
Broadbase dated August 17, 2000 with respect to non-disclosure of confidential
information, this Agreement and the exhibits hereto constitute the entire
understanding and agreement of the parties hereto with respect to the subject
matter hereof and supersede all prior and contemporaneous agreements or
understandings, inducements or conditions, express or implied, written or oral,
between the parties with respect to the subject matter hereof. The express terms
hereof control and supersede any course of performance or usage of trade
inconsistent with any of the terms hereof.

     13.2  Assignment; Binding Upon Successors and Assigns. Neither party hereto
may assign any of its rights or obligations hereunder without the prior written
consent of the other party hereto. This Agreement will be binding upon and inure
to the benefit of the parties hereto and their respective successors and
permitted assigns.

     13.3  No Third Party Beneficiaries. No provisions of this Agreement are
intended, nor will be interpreted, to provide or create any third party
beneficiary rights or any other rights of any kind in any client, customer,
affiliate, stockholder, partner, employee or any party hereto or any other
Person unless specifically provided otherwise herein, and, except as so
provided, all provisions hereof will be personal solely between the parties to
this Agreement.

     13.4  No Joint Venture. Nothing contained in this Agreement will be deemed
or construed as creating a joint venture or partnership between the parties
hereto. No party is by virtue of this Agreement authorized as an agent, employee
or legal representative of any other party. No party will have the power to
control the activities and operations of any other, and the parties' status is,
and at all times, will continue to be, that of independent contractors with
respect to each other. No party will have any power or authority to bind or
commit any other. No party will hold itself out as having any authority or
relationship in contravention of this Section.

     13.5  Construction of Agreement. This Agreement has been negotiated by the
respective parties hereto and their attorneys and have been reviewed by each
party hereto. Accordingly, no ambiguity in the language hereof will be construed
for or against either party.

     13.6  Severability. If any provision of this Agreement, or the application
thereof, is for any reason held to any extent to be invalid or unenforceable,
the remainder of this Agreement and application of such provision to other
persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto. The parties further agree to replace such
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the extent possible, the economic, business and other
purposes of the void or unenforceable provision.

                                      A-56
<PAGE>   273

     13.7  Section Headings. A reference to an Article, Section, Exhibit or
Schedule will mean an Article or Section in, or an Exhibit or Schedule to, this
Agreement, unless otherwise explicitly set forth. The titles and headings in
this Agreement are for reference purposes only and will not in any manner limit
the construction of this Agreement. For the purposes of such construction, this
Agreement will be considered as a whole.

     13.8  Amendment, Extension and Waivers. At any time prior to the Effective
Time, Broadbase, Newco and Servicesoft may, to the extent legally allowed: (a)
extend the time for performance of any of the obligations of the other party;
(b) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant thereto; and (c)
waive compliance with any of the agreements, covenants or conditions for the
benefit of such party contained herein. Any term or provision of this Agreement
may be amended. Any agreement to any amendment, extension or waiver will be
valid only if set forth in writing and signed by the party to be bound. The
waiver by a party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default or any succeeding
breach or default. The failure of any party to enforce any of the provisions
hereof will not be construed to be a waiver of the right of such party
thereafter to enforce such provisions. The Agreement may be amended by the
parties hereto at any time before or after approval of the Servicesoft
Stockholders, but, after such approval, no amendment will be made which by
applicable law requires the further approval of the Servicesoft Stockholders
without obtaining such further approval.

     13.9  Governing Law. The validity of this Agreement the construction of its
terms, and the interpretation and enforcement of the rights and duties of the
parties of this Agreement will be exclusively governed by and construed in
accordance with the internal laws of the State of Delaware, as applied to
agreements entered into solely between residents of and to be performed entirely
in the State of California, without reference to that body of law relating to
conflicts of law or choice of law.

     13.10  Dispute Resolution. Any dispute hereunder ("Dispute") shall be
settled by arbitration, to be held in Wilmington, Delaware, and, except as
herein specifically stated, in accordance with the commercial arbitration rules
of the American Arbitration Association ("AAA Rules") then in effect. However,
in all events, these arbitration provisions shall govern over any conflicting
rules which may now or hereafter be contained in the AAA Rules. Any judgment
upon the award rendered by the arbitrator may be entered in any court having
jurisdiction over the subject matter thereof. The arbitrator shall have the
authority to grant any equitable and legal remedies that would be available in
any judicial proceeding instituted to resolve a Dispute.

     (a) Compensation of Arbitrator. Any such arbitration will be conducted
before a single arbitrator who will be compensated for his or her services at a
rate to be determined by the parties or by the American Arbitration Association,
but based upon reasonable hourly or daily consulting rates for the arbitrator in
the event the parties are not able to agree upon his or her rate of
compensation.

     (b) Selection of Arbitrator. The American Arbitration Association will have
the authority to select an arbitrator from a list of arbitrators who are lawyers
familiar with Delaware contract law; provided, however, that such lawyers cannot
work for a firm then performing services for either party, that each party will
have the opportunity to make such reasonable objection to any of the arbitrators
listed as such party may wish and that the American Arbitration Association will
select the arbitrator from the list of arbitrators as to whom neither party
makes any such objection. In the event that the foregoing procedure is not
followed, each party will choose one person from the list of arbitrators
provided by the American Arbitration Association (provided that such person does
not have a conflict of interest), and the two persons so selected will select
from the list provided by the American Arbitration Association the person who
will act as the arbitrator.

     (c) Payment of Costs. Broadbase and Servicesoft, or Broadbase and the
Servicesoft Stockholders after the Closing, will bear the expense of deposits
and advances required by the arbitrator in equal proportions, but either party
may advance such amounts, subject to recovery as an addition or offset to any
award. The arbitrator will award to the prevailing party, as determined by the
arbitrator, all costs, fees and

                                      A-57
<PAGE>   274

expenses related to the arbitration, including reasonable fees and expenses of
attorneys, accountants and other professionals incurred by the prevailing party.

     (d) Burden of Proof. For any Dispute submitted to arbitration, the burden
of proof will be as it would be if the claim were litigated in a judicial
proceeding.

     (e) Award. Upon the conclusion of any arbitration proceedings hereunder,
the arbitrator will render findings of fact and conclusions of law and a written
opinion setting forth the basis and reasons for any decision reached and will
deliver such documents to each party to this Agreement along with a signed copy
of the award.

     (f) Terms of Arbitration. The arbitrator chosen in accordance with these
provisions will not have the power to alter, amend or otherwise affect the terms
of these arbitration provisions or the provisions of this Agreement.

     (g) Exclusive Remedy. Except as specifically otherwise provided in this
Agreement, arbitration will be the sole and exclusive remedy of the parties for
any Dispute arising out of this Agreement.

     13.11  Other Remedies. Except as otherwise provided in Section 12.3 or
elsewhere herein, any and all remedies herein expressly conferred upon a party
will be deemed cumulative with and not exclusive of any other remedy conferred
hereby or by law on such party, and the exercise of any one remedy will not
preclude the exercise of any other.

     13.12  Notices. Any notice or other communication required or permitted to
be given under this Agreement will be in writing, will be delivered personally
or by mail or express delivery, postage prepaid, and will be deemed given upon
actual delivery or, if mailed by registered or certified mail, on the third
business day following deposit in the mails, addressed as follows:

                           FIRST AMENDED AND RESTATED
                        CERTIFICATE OF INCORPORATION OF
                            BROADBASE SOFTWARE, INC.

                                   ARTICLE I

     The name of the corporation is Broadbase Software, Inc.

                                   ARTICLE II

     The address of the registered office of the corporation in the State of
Delaware is 15 E. North Street, City of Dover 19901, County of Kent. The name of
its registered agent at that address is Incorporating Services, Ltd.

                                  ARTICLE III

     The purpose of the corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of the
State of Delaware.

                                   ARTICLE IV

     A. Authorization of Shares. The total number of shares of all classes of
stock which the corporation has authority to issue is three hundred fifty-five
million (355,000,000) shares, consisting of two classes: three hundred fifty
million (350,000,000) shares of Common Stock, $0.001 par value per share, and
five million (5,000,000) shares of Preferred Stock, $0.001 par value per share.

     B. Designation of Future Series of Preferred Stock. The Board of Directors
is authorized, subject to any limitations prescribed by the law of the State of
Delaware, to provide for the issuance of the shares of Preferred Stock in one or
more series, and, by filing a certificate of designation pursuant to the
applicable law of the State of Delaware, to establish from time to time the
number of shares to be included in each such series, to fix the designation,
powers, preferences and rights of the shares of each such series and any
qualifications, limitations or restrictions thereof, and to increase or decrease
the number of shares of any such series (but not below the number of shares of
such series then outstanding). Subject to approval by the Board of Directors,
the number of authorized shares of Preferred Stock may be increased or decreased
(but not below the number of shares thereof then outstanding) by the affirmative
vote of the holders of a majority of the stock of the corporation entitled to
vote, unless a vote of any other holders is required pursuant to a certificate
or certificates establishing a series of Preferred Stock.

     Except as expressly provided in any certificate of designation designating
any series of Preferred Stock pursuant to the foregoing provisions of this
Article IV, any new series of Preferred Stock may be designated, fixed and
determined as provided herein by the Board of Directors without approval of the
holders of Common Stock or the holders of Preferred Stock, or any series
thereof, and any such new series may have powers, preferences and rights,
including, without limitation, voting rights, dividend rights, liquidation
rights, redemption rights and conversion rights, senior to, junior to or pari
passu with the rights of the Common Stock, the Preferred Stock, or any future
class or series of Preferred Stock or Common Stock.

     If the certificate of designation creating a series of Preferred Stock so
provides, any shares of a series of Preferred Stock that are acquired by the
corporation, whether by redemption, purchase, conversion or otherwise, so that
such shares are issued but not outstanding, may not be reissued as shares of
such series or as shares of the class of Preferred Stock. Upon the retirement of
any such shares and the filing of a certificate of retirement pursuant to
Sections 103 and 243 of the Delaware General Corporation Law with respect
thereto, the shares of such series shall be eliminated and the number of shares
of Preferred Stock shall be reduced accordingly.

                                   ARTICLE V

     The Board of Directors of the corporation shall have the power to adopt,
amend or repeal the Bylaws of the corporation.

                                   ARTICLE VI

     For the management of the business and for the conduct of the affairs of
the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

          (A) The conduct of the affairs of the corporation shall be managed
     under the direction of its Board of Directors. The number of directors
     shall be fixed from time to time exclusively by resolution of the Board of
     Directors.

          (B) Notwithstanding the foregoing provision of this Article VI, each
     director shall hold office until such director's successor is elected and
     qualified, or until such director's earlier death, resignation or removal.
     No decrease in the authorized number of directors constituting the Board of
     Directors shall shorten the term of any incumbent director.

          (C) Subject to the rights of the holders of any series of Preferred
     Stock, any vacancy occurring in the Board of Directors for any cause, and
     any newly created directorship resulting from any increase in the
     authorized number of directors, shall, unless (i) the Board of Directors
     determines by resolution that any such vacancies or newly created
     directorships shall be filled by the stockholders, or (ii) as otherwise
     provided by law, be filled only by the affirmative vote of a majority of
     the directors then in office, although less than a quorum, or by a sole
     remaining director, and not by the stockholders. Any director elected in
     accordance with the preceding sentence shall hold office for the remainder
     of the full term of the director for which the vacancy was created or
     occurred.

          (D) Subject to the rights of the holders of any series of Preferred
     Stock, any director or the entire Board of Directors may be removed, with
     or without cause, by the holders of at least a majority of the shares then
     entitled to vote at an election of directors; provided, however, that a
     director may not be removed without cause if the votes cast against removal
     of the director, or not consenting in writing to the removal, would be
     sufficient to elect the director if voted cumulatively (without regard to
     whether shares may otherwise be voted cumulatively) at an election at which
     the same total number of votes were cast (or, if the action is taken by
     written consent, all shares entitled to vote were voted) and either the
     number of directors elected at the most recent annual meeting of
     stockholders, or if greater, the number of directors for whom removal is
     being sought, were then being elected.

          (E) Subject to the rights of the holders of any series of Preferred
     Stock to elect additional directors under specified circumstances, the
     directors shall be divided, with respect to the time for which they
     severally hold office, into three classes designated as Class I, Class II
     and Class III, respectively. Directors shall be assigned to each class in
     accordance with a resolution or resolutions adopted by the Board of
     Directors, with the number of directors in each class to be divided as
     equally as reasonably possible. The term of office of the Class I directors
     shall expire at the corporation's 2000 annual meeting of stockholders, the
     term of office of the Class II directors shall expire at the corporation's
     2001 annual meeting of stockholders, and the term of office of the Class
     III directors shall expire at the corporation's 2002 annual meeting of
     stockholders. At each annual meeting of stockholders commencing with the
     corporation's 2000 annual meeting of stockholders, directors elected to
     succeed those directors of the class whose terms then expire shall be
     elected for a term of office to expire at the third succeeding annual
     meeting of stockholders after their election.

          (F) Election of directors need not be by written ballot unless the
     Bylaws of the corporation shall so provide.

                                       B-2
<PAGE>   279

          (G) No action shall be taken by the stockholders of the corporation
     except at an annual or special meeting of stockholders called in accordance
     with the Bylaws of the corporation, and no action shall be taken by the
     stockholders by written consent.

          (H) Advance notice of stockholder nominations for the election of
     directors of the corporation and of business to be brought by stockholders
     before any meeting of stockholders of the corporation shall be given in the
     manner provided in the Bylaws of the corporation. Business transacted at
     special meetings of stockholders shall be confined to the purpose or
     purposes stated in the notice of meeting.

                                  ARTICLE VII

     To the fullest extent permitted by law, no director of the corporation
shall be personally liable for monetary damages for breach of fiduciary duty as
a director. Without limiting the effect of the preceding sentence, if the
Delaware General Corporation Law is hereafter amended to authorize the further
elimination or limitation of the liability of a director, then the liability of
a director of the corporation shall be eliminated or limited to the fullest
extent permitted by the Delaware General Corporation Law, as so amended.

     Neither any amendment nor repeal of this Article VII, nor the adoption of
any provision of this Certificate of Incorporation inconsistent with this
Article VII, shall eliminate, reduce or otherwise adversely affect any
limitation on the personal liability of a director of the corporation existing
at the time of such amendment, repeal or adoption of such an inconsistent
provision.

     A. Concurrently with the execution of this Agreement, Broadbase,

hereafter be amended from time to time, the "Merger Agreement") which provides
for the merger of Merger Sub with and into Servicesoft (the "Merger"). Pursuant
to the Merger, shares of common stock of Servicesoft, par value $0.01 per share
("Servicesoft Common Stock") will be converted into shares of common stock of
Broadbase, par value $.001 per share ("Broadbase Common Stock") on the basis
described in the Merger Agreement. Capitalized terms used but not defined herein
shall have the meanings ascribed to such terms in the Merger Agreement.

     B. Stockholder owns of record or has the power to direct the voting with
respect to such number of Shares (as defined herein) as are indicated on the
final page of this Agreement;

     C. Stockholder is entering into this Agreement as a material inducement and

     NOW, THEREFORE, in consideration of the foregoing and the mutual premises,
representations, warranties, covenants and agreements contained herein, the
parties hereto hereby agree as follows:

     1. Definitions.

     (b) "Shares" means all issued and outstanding shares of Broadbase Common
Stock owned of record by Stockholder or over which Stockholder exercises voting
power, in each case, as of the record date for persons entitled (i) to receive
notice of, and to vote at the meeting of the stockholders of Broadbase called
for the purpose of voting on the matters referred to in Section 2.1, or (ii) to
take action by written consent of the stockholders of Broadbase with respect to
the matters referred to in Section 2.1; provided, however, that any shares of
capital stock of Broadbase that Stockholder purchases or with respect to which
Stockholder otherwise exercises voting power after the execution of this
Agreement and prior to the Expiration Date shall be subject to the terms and
conditions of this Agreement to the same extent as if they constituted Shares on
the date hereof.

     (c) "Transfer" with respect to any security means to directly or
indirectly: (i) sell, pledge, encumber, transfer or disposes of, or grant an
option with respect to, such security or any interest in such security; or (ii)
enter into an agreement or commitment providing for the sale, pledge,
encumbrance, transfer or disposition of, or grant of an option with respect to,
such security or any interest therein.

     2. Agreement to Vote.

     2.1  Voting Agreement. Stockholder hereby covenants and agrees that, prior
to the Expiration Date, at any meeting (whether annual or special and whether or
not an adjourned or postponed meeting) of the stockholders of Broadbase, however
called, unless otherwise directed in writing by Servicesoft, Stockholder will
appear at the meeting or otherwise cause the Shares to be counted as present
thereat for purposes of establishing a quorum and vote or consent (or cause to
be voted or consented) the Shares

                                       C-1
<PAGE>   281

     (a) in favor of the Merger, the execution and delivery by Broadbase of the
Merger Agreement and the adoption and approval of the terms thereof, including
the issuance of the Exchange Shares pursuant to the Merger, and in favor of the
other actions contemplated by the Merger Agreement and any action required in
furtherance hereof and thereof;

     (b) in favor of an amendment to Broadbase's Certificate of Incorporation to
increase the authorized number of shares of Broadbase Common Stock in order to
permit the issuance of the Exchange Shares pursuant to the Merger; and

     (c) against the approval of any proposal made in opposition to or in
competition with the issuance of the Exchange Shares pursuant to the Merger,
including, without limitation, any Broadbase Acquisition.

     Prior to the Expiration Date, Stockholder will not enter into any agreement
or understanding with any person or entity to vote or give instructions in any
manner inconsistent with any provision of this Section 2.1.

     2.2  Irrevocable Proxy. Contemporaneously with the execution of this
Agreement, Stockholder will deliver to Servicesoft a proxy with respect to the
Shares in the form attached hereto as Exhibit 1, which proxy will be irrevocable
to the fullest extent permitted by applicable law (the "Proxy").

     2.3  Transfer and Other Restrictions. Prior to the termination of this
Agreement, Stockholder agrees not to, directly or indirectly:

          (i) grant any proxy, power of attorney, deposit any of the Shares into
     a voting trust or enter into a voting agreement or arrangement with respect
     to the Shares except as provided in this Agreement; or

          (ii) take any other action that would make any representation or
     warranty of Stockholder contained herein untrue or incorrect or have the
     effect of preventing or disabling Stockholder from performing its
     obligations under this Agreement.

     4. Representations, Warranties and Covenants of Stockholder. Stockholder
hereby represents, warrants and covenants as follows:

          4.1  Authority, Enforceability. Stockholder has full power and
     authority to enter into, execute, deliver and perform Stockholder's
     obligations under this Agreement and to make the representations,
     warranties and covenants contained herein. This Agreement has been duly
     executed and delivered by Stockholder and constitutes a legal, valid and
     binding obligation of Stockholder, enforceable against Stockholder in
     accordance with its terms, 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.

          4.2  No Conflicts, No Defaults and Consents. The execution and
     delivery of this Agreement by Stockholder do not, and the performance of
     this Agreement by Stockholder will not: (i) conflict with or violate any
     order, decree or judgment applicable to Stockholder or by which Stockholder
     or any of Stockholder's properties or Shares is bound or affected; (ii)
     violate any agreement to which Stockholder is a party or is subject,
     including, without limitation, any voting agreement or voting trust; (iii)
     result in any breach of or constitute a default (with notice or lapse of
     time, or both) under, or give to others any rights of termination,
     amendment, acceleration or cancellation of, or result in the creation of
     any lien, restriction, adverse claim, option on, right to acquire, or any
     encumbrance or security interest in or to any of the Shares, pursuant to
     any written, oral or other agreement, contract or legally binding
     commitment to which Stockholder is a party or by which Stockholder or any
     of Stockholder's properties (including, without limitation, the Shares) is
     bound or affected, or (iv) require any written, oral or other agreement,
     contract or legally binding commitment of any third party.

          4.3  Shares Owned. As of the Effective Date of this Agreement,
     Stockholder owns of record or has the power to direct the voting with
     respect to, in the aggregate, the number of shares of

                                       C-2
<PAGE>   282

     Broadbase Common Stock set forth below Stockholder's name on the signature
     page of this Agreement, and does not own of record, or have the power to
     direct the voting with respect to, any shares of capital stock of
     Broadbase, other than the shares set forth below Stockholder's name on the
     signature page hereof.

          4.4  Accuracy of Representations; Reliance by Servicesoft. The
     representations and warranties contained in this Agreement are accurate in
     all respects as of the date of this Agreement, will be accurate in all
     respects at all times through the Expiration Date and will be accurate in
     all respects as of the Effective Time of the Merger as if made on that date
     except as to representations that speak only as of the date of this
     Agreement. Stockholder understands and acknowledges that Servicesoft is
     entering into the Merger Agreement in reliance upon Stockholder's execution
     and delivery of this Agreement.

          4.5  Further Assurances. Stockholder agrees to execute and deliver any
     additional documents reasonably necessary or desirable, in the opinion of
     Broadbase or Servicesoft, to carry out the purposes and intent of this
     Agreement and the Proxy.

     5. Miscellaneous.

     5.1  Severability. If any provision of this Agreement is found by any
arbitrator or court of competent jurisdiction to be invalid or unenforceable,
then the parties hereby waive such provision to the extent that it is found to
be invalid or unenforceable and to the extent that to do so would not deprive
one of the parties of the substantial benefit of its bargain. Such provision
will, to the extent allowable by law and the preceding sentence, not be voided
or canceled but will instead be modified by such arbitrator or court so that it
becomes enforceable and, as modified, will be enforced as any other provision
hereof, all the other provisions hereof continuing in full force and effect.

     5.2  Amendment; Waiver. This Agreement may be amended, modified,
superseded, canceled, renewed or extended only by an agreement in writing
executed by Servicesoft and Stockholder. The failure by either party at any time
to require performance or compliance by the other of any of its obligations or
agreements will in no way affect the right to require such performance or
compliance at any time thereafter. The waiver by either party of a breach of any
provision of this Agreement will not be treated as a waiver of any preceding or
succeeding breach of such provision or as a waiver of the provision itself. No
waiver of any kind will be effective or binding, unless it is in writing and is
signed by the party against whom such waiver is sought to be enforced.

     5.3  Entire Agreement. This Agreement, together with the Merger Agreement,
constitutes the entire agreement between the parties with respect to the subject
matter hereof and supersedes all other prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof.

     5.4  Assignment. This Agreement and all rights and obligations hereunder
are personal to Stockholder and may not be transferred or assigned by
Stockholder at any time. Servicesoft may assign its rights, and may delegate its
obligations hereunder, to any parent, subsidiary or affiliate of Servicesoft;
provided, however, that any such assignee assumes Servicesoft's obligations
hereunder. This Agreement will be binding upon, and inure to the benefit of, the
persons or entities who are permitted, by the terms of this Agreement, to be
successors, assigns and personal representatives of the respective parties
hereto.

     5.5  Governing Law. This Agreement will be governed by and construed in
accordance with the internal laws of the State of Delaware, excluding that body
of laws pertaining to conflict of laws.

     5.6  Costs of Enforcement. If any party to this Agreement seeks to enforce
its rights under this Agreement by legal proceedings or otherwise, the
non-prevailing party will pay all costs and expenses incurred by the prevailing
party, including, without limitation, all reasonable attorneys' and experts'
fees.

<PAGE>   283

     5.7  Notices. Any and all notices required or permitted to be given to a
party pursuant to the provisions of this Agreement will be in writing and will
be effective and deemed to provide such party sufficient notice under this
Agreement on the earliest of the following: (i) at the time of personal
delivery, if delivery is in person; (ii) one (1) business day after deposit with
an express overnight courier for United States deliveries, or two (2) business
days after such deposit for deliveries outside of the United States; or (iii)
three (3) business days after deposit in the United States mail by registered or

                               IRREVOCABLE PROXY

     The undersigned stockholder (the "Stockholder") of Broadbase, Inc., a
Delaware corporation ("Broadbase"), hereby irrevocably (to the fullest extent
permitted by applicable law) appoints and constitutes the members of the Board
of Directors of Servicesoft, Inc., a Delaware corporation ("Servicesoft"), and
each of them (collectively the "Proxyholders"), the agents, attorneys and
proxies of the undersigned, with full power of substitution and resubstitution,
to the fullest extent of the undersigned's rights with respect to (i) the shares
of capital stock of Broadbase owned of record by the undersigned, or over which
the undersigned has voting power, as of the date of this proxy, which shares are
specified on the final page of this proxy; (ii) any and all other shares of
capital stock of Broadbase which the undersigned may acquire or with respect to
which the undersigned shall acquire voting power after the date hereof,
including without limitation, in the event of a dividend or distribution of
capital stock of Broadbase, or any change in Broadbase's capital stock by reason
of any stock dividend, split-up, recapitalization, combination, exchange of
shares or the like, all shares of Broadbase's capital stock issued or
distributed pursuant to such stock dividends and distributions and any shares of
Broadbase's capital stock into which or for which any or all of the shares
otherwise held by the undersigned may be so changed or exchanged. (The shares of
the capital stock of Broadbase referred to in clauses (i) and (ii) of the
immediately preceding sentence are collectively referred to as the "Shares.")
Upon the execution hereof, all prior proxies given by the undersigned with
respect to any of the Shares are hereby revoked, and no subsequent proxies will
be given with respect to any of the Shares until such time as this proxy shall
be terminated in accordance with its terms.

     The Proxyholders named above will be empowered, and may exercise this
proxy, to vote the Shares at any time until the Expiration Date (as defined in
the Voting Agreement dated as of the date hereof, between Servicesoft and the
undersigned (the "Voting Agreement")) at any meeting of the stockholders of
Broadbase, however called, or in any action by written consent of stockholders
of Broadbase:

          (i) in favor of the merger (the "Merger") contemplated by the
     Agreement and Plan of Merger by and among Broadbase, Soldier Acquisition
     Corp., and Servicesoft, dated as of the date hereof (the "Merger
     Agreement"), the execution and delivery by Broadbase of the Merger
     Agreement and the adoption and approval of the terms thereof and in favor
     of the other actions contemplated by the Merger Agreement and any action
     required in furtherance hereof and thereof;

          (ii) against any action or agreement that would result in a breach of
     any representation, warranty, covenant or obligation of Broadbase in the
     Merger Agreement or that would preclude fulfillment of a condition
     precedent under the Merger Agreement to Servicesoft's or Broadbase's
     obligation to consummate the Merger; and

          (iii) against approval of any proposal made in opposition to or in
     competition with the consummation of the Merger including, without
     limitation, any Acquisition Proposal or Superior Offer (each as defined in
     the Merger Agreement).

     The Proxyholders may not exercise this proxy on any other matter. The
Stockholder may vote the Shares on all such other matters. The proxy granted by
the Stockholder to the Proxyholders hereby is granted as of the date of this
Irrevocable Proxy in order to secure the obligations of the Stockholder set
forth in Section 2 of the Voting Agreement.

     This proxy will terminate upon the termination of the Voting Agreement in
accordance with its terms. Any obligation of the undersigned hereunder shall be
binding upon the successors and assigns of the undersigned. The undersigned
Stockholder authorizes the Proxyholders to file this proxy and any substitution
or revocation of substitution with the Secretary of Broadbase and with any
Inspector of Elections at any meeting of the stockholders of Broadbase.

     This proxy is irrevocable, is coupled with an interest, and shall survive
the insolvency, incapacity, death or liquidation of the undersigned and will be
binding upon the heirs, successors and assigns of the undersigned (including any
transferee of any of the Shares).

               SERVICESOFT VOTING AGREEMENT AND IRREVOCABLE PROXY

     THIS VOTING AGREEMENT AND IRREVOCABLE PROXY (this "Agreement") is made and
entered into as of September 18, 2000 (the "Effective Date"), by and between
Broadbase Software, Inc., a Delaware corporation ("Broadbase"), and the
undersigned stockholder ("Stockholder") of Servicesoft, Inc., a Delaware
corporation ("Servicesoft").

                                    RECITALS

     A. Concurrently with the execution of this Agreement, Broadbase,
Servicesoft and Soldier Acquisition Corporation, a Delaware corporation and a
wholly-owned subsidiary of Broadbase ("Merger Sub"), are entering into an
Agreement and Plan of Merger of even date herewith (as such agreement may
hereafter be amended from time to time, the "Merger Agreement") which provides
for the merger of Merger Sub with and into Servicesoft (the "Merger"). Pursuant
to the Merger, shares of common stock of Servicesoft, par value $0.01 per share
("Servicesoft Common Stock") will be converted into shares of common stock of
Broadbase, par value $.001 per share ("Broadbase Common Stock") on the basis
described in the Merger Agreement; capitalized terms that are used in this
Agreement and are not otherwise defined herein will have the same meanings that
such terms have in the Merger Agreement.

     B. Stockholder owns of record or has the power to direct the voting with
respect to such number of Shares (as defined herein) as are indicated on the
final page of this Agreement;

     C. Stockholder is entering into this Agreement as a material inducement and
consideration to Broadbase to enter into the Merger Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual premises,
representations, warranties, covenants and agreements contained herein, the
parties hereto hereby agree as follows:

     1. Definitions.

     (a) "Expiration Date" means the earlier to occur of (i) the Effective Time
of the Merger; and (ii) such time as the Merger Agreement may be terminated in
accordance with its terms.

     (c) "Shares" means all issued and outstanding shares of Servicesoft Common
Stock or each series of Servicesoft preferred stock owned of record by
Stockholder or over which Stockholder exercises voting power, in each case, as
of the record date for persons entitled (i) to receive notice of, and to vote at
the meeting of the stockholders of Servicesoft called for the purpose of voting
on the matters referred to in Section 2.1, or (ii) to take action by written
consent of the stockholders of Servicesoft with respect to the matters referred
to in Section 2.1; provided, however, that any shares of capital stock of
Servicesoft that Stockholder purchases or with respect to which Stockholder
otherwise exercises voting power after the execution of this Agreement and prior
to the Expiration Date shall be subject to the terms and conditions of this
Agreement to the same extent as if they constituted Shares on the date hereof.

     (d) "Transfer" with respect to any security means to directly or
indirectly: (i) sell, pledge, encumber, transfer or dispose of, or grant an
option with respect to, such security or any interest in such security; or (ii)
enter into an agreement or commitment providing for the sale, pledge,
encumbrance, transfer or disposition of, or grant of an option with respect to,
such security or any interest therein.

     2. Agreement to Vote.

     2.1  Voting Agreement. Stockholder hereby covenants and agrees that, prior
to the Expiration Date, at any meeting (whether annual or special and whether or
not an adjourned or postponed meeting) of the stockholders of Servicesoft,
however called, and in any action taken by the written consent of stockholders
of Servicesoft without a meeting, unless otherwise directed in writing by
Broadbase, Stockholder will

                                       D-1
<PAGE>   288

appear at the meeting or otherwise cause the Shares to be counted as present
thereat for purposes of establishing a quorum and vote or consent for cause to
be voted or consented the Shares:

          (a) in favor of the Merger, the execution and delivery by Servicesoft
     of the Merger Agreement and the adoption and approval of the terms thereof
     and in favor of the other actions contemplated by the Merger Agreement and,
     to the extent that a vote is solicited in connection with this Voting
     Agreement or the Merger Agreement, any other action required in furtherance
     hereof or thereof;

          (b) against any action or agreement that would result in a breach of
     any representation, warranty, covenant or obligation of Servicesoft in the
     Merger Agreement or that would preclude fulfillment of a condition
     precedent under the Merger Agreement to Servicesoft's or Broadbase's
     obligation to consummate the Merger; and

          (c) against approval of any proposal made in opposition to or in
     competition with the consummation of the Merger, including, without
     limitation, any Acquisition Proposal or Superior Offer (each as defined in
     the Merger Agreement).

     Prior to the Expiration Date, Stockholder will not enter into any agreement
or understanding with any person or entity to vote or give instructions in any
manner inconsistent with any provision of this Section 2.1.

     2.2  Irrevocable Proxy. Contemporaneously with the execution of this
Agreement, Stockholder will deliver to Broadbase a proxy with respect to Shares
in the form attached hereto as Exhibit 1, which proxy will be irrevocable to the
fullest extent permitted by applicable law (the "Proxy").

     2.3 Transfer and Other Restrictions. (a) Prior to the termination of this
Agreement, Stockholder agrees not to, directly or indirectly:

          (i) except pursuant to the terms of the Merger Agreement, Transfer any
     or all of the Shares or any interest therein except as provided in Section
     2.2 hereof;

          (ii) grant any proxy, power of attorney, deposit any of the Shares
     into a voting trust or enter into a voting agreement or arrangement with
     respect to the Shares except as provided in this Agreement; or

          (iii) take any other action that would make any representation or
     warranty of Stockholder contained herein untrue or incorrect or have the
     effect of preventing or disabling Stockholder from performing its
     obligations under this Agreement.

     (b) To the extent Stockholder is, as of the date hereof, party to a
contract or agreement that requires Stockholder to Transfer Shares to another
person or entity (excluding a contract or agreement pledging Shares to
Servicesoft), Stockholder will not effect any such Transfer unless and until the
transferee agrees to be bound by and executes an agreement in the form of this
Agreement with respect to the Shares to be Transferred. Nothing herein shall
prohibit Stockholder from exercising (in accordance with the terms of the option
or warrant, as applicable) any option or warrant Stockholder may hold; provided,
however, that the securities acquired upon such exercise shall be deemed Shares.

     (c) Stockholder agrees with, and covenants to, Broadbase that Stockholder
shall not request that Servicesoft register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing any
Shares, unless such transfer is made pursuant to and in compliance with this
Agreement.

     3. Waivers. Stockholder agrees not to exercise any rights of appraisal and
any dissenters' rights that Stockholder may have (whether under applicable law
or otherwise) or could potentially have or acquire in connection with the
Merger.

     4. Representations, Warranties and Covenants of Stockholder. Stockholder
hereby represents, warrants and covenants as follows:

     4.1  Authority, Enforceability. Stockholder has full power and authority to
enter into, execute, deliver and perform Stockholder's obligations under this
Agreement and to make the representations,
                                       D-2
<PAGE>   289

warranties and covenants contained herein. This Agreement has been duly executed
and delivered by Stockholder and constitutes a legal, valid and binding
obligation of Stockholder, enforceable against Stockholder in accordance with
its terms, 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.

     4.2  No Conflicts, No Defaults and Consents. The execution and delivery of
this Agreement by Stockholder do not, and the performance of this Agreement by
Stockholder will not: (i) conflict with or violate any order, decree or judgment
applicable to Stockholder or by which Stockholder or any of Stockholder's
properties or Shares is bound or affected; (ii) violate any agreement to which
Stockholder is a party or is subject, including, without limitation, any voting
agreement or voting trust; (iii) result in any breach of or constitute a default
(with notice or lapse of time, or both) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of any lien, restriction, adverse claim, option on, right to acquire,
or any encumbrance or security interest in or to any of the Shares, pursuant to
any written, oral or other agreement, contract or legally binding commitment to
which Stockholder is a party or by which Stockholder or any of the Shares is
bound or affected, or (iv) require any written, oral or other agreement,
contract or legally binding commitment of any third party.

     4.3  Certain Agreements. Stockholder is not a party to any agreement with
Servicesoft or any subsidiary of Servicesoft (i) the benefits of which are
contingent, or the terms of which are materially altered, upon the occurrence of
a transaction in the nature of any transaction contemplated by the Merger
Agreement, (ii) providing any term of employment or compensation guarantee, or
(iii) providing severance benefits or other benefits after termination of
employment regardless of the reason for such termination of employment, in each
case, except as set forth in the Servicesoft Disclosure Letter.

     4.4  Shares Owned. As of the Effective Date of this Agreement, Stockholder
owns of record or has the power to direct the voting with respect to, in the
aggregate the number of shares of Servicesoft Common Stock and of each series of
Servicesoft Preferred Stock set forth below Stockholder's name on the signature
page of this Agreement, and does not own of record, or have the power to direct
the voting with respect to, any shares of capital stock of Servicesoft other
than the Shares set forth below Stockholder's name on the signature page hereof.
All Shares are, and at all times until and through the Expiration Date will be,
free and clear of any rights of first refusal, co-sale rights, security
interests, liens, pledges, claims, options, charges or other encumbrances,
except as set forth in the Servicesoft Disclosure Letter.

     4.5  Accuracy of Representations; Reliance by Broadbase. The
representations and warranties contained in this Agreement are accurate in all
respects as of the date of this Agreement, will be accurate in all respects at
all times through the Expiration Date and will be accurate in all respects as of
the Effective Time of the Merger as if made on that date. Stockholder
understands and acknowledges that Broadbase is entering into the Merger
Agreement in reliance upon Stockholder's execution and delivery of this
Agreement.

     4.6  Further Assurances. Stockholder agrees to execute and deliver any
additional documents reasonably necessary or desirable, in the opinion of
Broadbase or Servicesoft, to carry out the purposes and intent of this Agreement
and the Proxy.

     5. Miscellaneous.

     5.1  Severability. If any provision of this Agreement is found by any
arbitrator or court of competent jurisdiction to be invalid or unenforceable,
then the parties hereby waive such provision to the extent that it is found to
be invalid or unenforceable and to the extent that to do so would not deprive
one of the parties of the substantial benefit of its bargain. Such provision
will, to the extent allowable by law and the preceding sentence, not be voided
or canceled but will instead be modified by such arbitrator or court so that it
becomes enforceable and, as modified, will be enforced as any other provision
hereof, all the other provisions hereof continuing in full force and effect.

                                       D-3
<PAGE>   290

     5.2  Amendment; Waiver. This Agreement may be amended, modified,
superseded, canceled, renewed or extended only by an agreement in writing
executed by Broadbase and Stockholder. The failure by either party at any time
to require performance or compliance by the other of any of its obligations or
agreements will in no way affect the right to require such performance or
compliance at any time thereafter. The waiver by either party of a breach of any
provision of this Agreement will not be treated as a waiver of any preceding or
succeeding breach of such provision or as a waiver of the provision itself. No
waiver of any kind will be effective or binding, unless it is in writing and is
signed by the party against whom such waiver is sought to be enforced.

     5.3  Entire Agreement. This Agreement, together with the Merger Agreement,
constitutes the entire agreement between the parties with respect to the subject
matter hereof and supersedes all other prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof.

     5.4  Assignment. This Agreement and all rights and obligations hereunder
are personal to Stockholder and may not be transferred or assigned by
Stockholder at any time. Broadbase may assign its rights, and may delegate its
obligations hereunder, to any parent, subsidiary, affiliate or successor of
Broadbase, or in connection with any sale, transfer or other disposition of all
or substantially all the business and assets of Broadbase or any of its
subsidiaries or affiliates, whether by sale of stock, sale of assets, merger,
consolidation or otherwise; provided however, that any such assignee assumes
Broadbase's obligations hereunder. This Agreement will be binding upon, and
inure to the benefit of, the persons or entities who are permitted, by the terms
of this Agreement, to be successors, assigns and personal representatives of the
respective parties hereto.

     5.5  Governing Law. This Agreement will be governed by and construed in
accordance with the internal laws of the State of Delaware, excluding that body
of laws pertaining to conflict of laws.

     5.6  Costs of Enforcement. If any party to this Agreement seeks to enforce
its rights under this Agreement by legal proceedings or otherwise, the
non-prevailing party will pay all costs and expenses incurred by the prevailing
party, including, without limitation, all reasonable attorneys' and experts'
fees.

     5.7  Notices. Any and all notices required or permitted to be given to a
party pursuant to the provisions of this Agreement will be in writing and will
be effective and deemed to provide such party sufficient notice under this
Agreement on the earliest of the following: (i) at the time of personal
delivery, if delivery is in person; (ii) one (1) business day after deposit with
an express overnight courier for United States deliveries, or two (2) business
days after such deposit for deliveries outside of the United States; or (iii)
three (3) business days after deposit in the United States mail by registered or
certified mail (return receipt requested) for United States deliveries. All
notices for delivery outside the United States will be sent by express courier.
All notices not delivered personally will be sent with postage and/or other
charges prepaid and properly addressed to the party to be notified at the
address set forth below, or at such other address as such other party may
designate by ten (10) days advance written notice to the other parties hereto.

                               IRREVOCABLE PROXY

     The undersigned stockholder (the "Stockholder") of Servicesoft, Inc., a
Delaware corporation ("Servicesoft"), hereby irrevocably (to the fullest extent
permitted by applicable law) appoints and constitutes Rusty Thomas, Eric
Willgohs and/or the members of the Board of Directors of Broadbase, Inc., a
Delaware corporation ("Broadbase"), and each of them (collectively the
"Proxyholders"), the agents, attorneys and proxies of the undersigned, with full
power of substitution and resubstitution, to the fullest extent of the
undersigned's rights with respect to (i) the shares of capital stock of
Servicesoft owned of record by the undersigned, or over which the undersigned
has voting power, as of the date of this proxy, which shares are specified on
the final page of this proxy; (ii) any and all other shares of capital stock of
Servicesoft which the undersigned may acquire or with respect to which the
undersigned shall acquire voting power after the date hereof, including, without
limitation, in the event of a dividend or distribution of capital stock of
Servicesoft, or any change in Servicesoft's capital stock by reason of any stock
dividend, split-up, recapitalization, combination, exchange of shares or the
like, all shares of Servicesoft's capital stock issued or distributed pursuant
to such stock dividends and distributions and any shares of Servicesoft's
capital stock into which or for which any or all of the shares otherwise held by
the undersigned may be so changed or exchanged. (The shares of the capital stock
of Servicesoft referred to in clauses (i) and (ii) of the immediately preceding
sentence are collectively referred to as the "Shares.") Upon the execution
hereof, all prior proxies given by the undersigned with respect to any of the
Shares are hereby revoked, and no subsequent proxies will be given with respect
to any of the Shares until such time as this proxy shall be terminated in
accordance with its terms.

     The Proxyholders named above will be empowered, and may exercise this
proxy, to vote the Shares at any time until the Expiration Date (as defined in
the Voting Agreement) at any meeting of the stockholders of Servicesoft, however
called, or in any action by written consent of stockholders of Servicesoft:

          (i) in favor of the merger (the "Merger") contemplated by the

     Corp., and Servicesoft, dated as of the date hereof (the "Merger
     Agreement"), the execution and delivery by Servicesoft of the Merger

     of the other actions contemplated by the Merger Agreement and, to the
     extent that a vote is solicited in connection with this Voting Agreement or
     the Merger Agreement, any other action required in furtherance hereof or
     thereof;

          (ii) against any action or agreement that would result in a breach of
     any representation, warranty, covenant or obligation of Servicesoft in the
     Merger Agreement or that would preclude fulfillment of a condition
     precedent under the Merger Agreement to Servicesoft's or Broadbase's
     obligation to consummate the Merger; and

          (iii) against approval of any proposal made in opposition to or in
     competition with the consummation of the Merger including, without
     limitation, any Acquisition Proposal or Superior Offer (each as defined in
     the Merger Agreement).

     The Proxyholders may not exercise this proxy on any other matter. The

     This proxy will terminate upon the termination of the Voting Agreement in
accordance with its terms. Any obligation of the undersigned hereunder shall be
binding upon the successors and assigns of the undersigned. The undersigned
Stockholder authorizes the Proxyholders to file this proxy and any substitution
or revocation of substitution with the Secretary of Servicesoft and with any
Inspector of Elections at any meeting of the stockholders of Servicesoft.

                                ESCROW AGREEMENT

     THIS ESCROW AGREEMENT is made and entered into as of             , 2000 by
and among Broadbase Software, Inc., a Delaware corporation ("Broadbase"), Mark
Skapinker, as representative (the "Representative") of all of the holders of
common stock (the "Stockholders") of SERVICESOFT, Inc., a Delaware corporation
("Servicesoft"), and State Street Bank and Trust Company of California, N.A.
(the "Escrow Agent").

                                    RECITALS

     A. Broadbase, Servicesoft and Soldier Acquisition Corp., a Delaware
corporation and wholly owned subsidiary of Broadbase ("Merger Sub"), have
entered into an Agreement and Plan of Merger (the "Merger Agreement") dated as
of September 18, 2000, pursuant to which Merger Sub will merge with and into
Servicesoft in a reverse triangular merger (the "Merger"), with Servicesoft to
be the surviving corporation of the Merger. Capitalized terms used in this
Agreement and not otherwise defined herein shall have the meanings given to such
terms in the Merger Agreement, a copy of which is attached hereto;

     B. Section 2.2 of the Merger Agreement provides that, at the Effective
Time, Broadbase will be entitled to withhold from the Stockholders an aggregate
number of the shares of Broadbase common stock equal to ten percent (10%) of the
shares of Broadbase common stock issuable to the Stockholders at the Effective
Time for the purpose of securing the Stockholders' indemnification obligations
to Broadbase and the other Indemnified Persons pursuant to the terms and
conditions set forth in Article 12 of the Merger Agreement and in this
Agreement;

     C. The Representative is entering into this Agreement on behalf of the
Stockholders as a material inducement and consideration for Broadbase to enter
into the Merger Agreement and to consummate the transactions contemplated
therein and as a material inducement and condition precedent to consummation of
the Merger; and

     D. The parties desire to set forth in this Agreement the terms and
conditions pursuant to which the Escrow Shares shall be deposited in, held in
and delivered from an escrow account.

     NOW, THEREFORE, in consideration of the facts stated in the foregoing
recitals and the mutual promises hereinafter set forth, the parties hereby agree
as follows:

     1. Escrow and Indemnification

     1.1  Establishment of Escrow.

     (a) Deposit of Escrow Shares. On the Closing Date, Broadbase will deposit
with U.S. Stock Corporation, transfer agent for Broadbase common stock (the
"Exchange Agent"), the Exchange Shares, including shares to be subsequently held
in escrow. The Exchange Agent will give the Escrow Agent prompt written notice
of the Closing Date and Effective Time of the Merger. Promptly after the
Closing, the Exchange Agent will issue to the Escrow Agent the Escrow Shares to
be withheld from the Stockholders upon the surrender of their Servicesoft
Certificates (including any Additional Escrow Shares, as defined in Section
2.1(b)), each registered in the name of the applicable Stockholder.

     (b) Delivery of Stock Powers. As promptly as practicable after receipt of
the letter of transmittal from the Exchange Agent, each Stockholder will deliver
to the Escrow Agent three duly endorsed stock powers (each a "Stock Power")
substantially in the form attached hereto as Exhibit A and bearing a "medallion"
signature guarantee. In the event any Additional Escrow Shares are issued, or if
the Escrow Agent reasonably requires an additional Stock Power to effect a
transfer, each Stockholder will, upon request, promptly execute and deliver an
additional Stock Power to the Escrow Agent.

                                       E-1
<PAGE>   296

     (c) Legends. Stock certificates representing Escrow Shares will (until they
are released to the Stockholders or Broadbase in accordance with this Agreement)
bear the following legend indicating that they are subject to this Agreement (in
addition to any other legends which might be applicable to such shares):

        "THE SECURITIES REPRESENTED HEREBY MAY BE OFFERED, SOLD OR OTHERWISE
        TRANSFERRED, PLEDGED OR HYPOTHECATED ONLY IN ACCORDANCE WITH THE TERMS
        OF AN ESCROW AGREEMENT AMONG THE ISSUER, THE HOLDER THEREOF AND STATE
        STREET BANK AND TRUST COMPANY OF CALIFORNIA, N.A. A COPY OF SUCH
        AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE ISSUER."

Such legend shall be removed from certificates representing Escrow Shares prior
to the release of such Escrow Shares.

     (d) Investments of Cash. The Escrow Agent shall invest cash, if any, held
in the Escrow, other than amounts immediately distributable by the Escrow Agent,
in the SSgA U.S. Treasury Money Market Fund. For tax reporting and withholding
purposes, the income on such investments shall be allocated to the Stockholders
in accordance with their proportionate interests in the Escrow Shares as set
forth in the Escrow Ledger (defined in Section 2.2).

     1.2  Indemnification. Broadbase and the other Indemnified Persons are
entitled to be indemnified by the Stockholders pursuant to the terms of Article
12 of the Merger Agreement against any Damages during the Escrow Period. Each of
the Stockholders has agreed to the use of the Escrow Shares as collateral for
these indemnity obligations, subject to the terms and limitations set forth in
Article 12 of the Merger Agreement and in this Agreement.

     2. Ownership Interests in and Release of the Escrow Shares

     2.1  Stockholders' Interests in the Escrow Shares.

     (a) Individual Stockholder Interests. The Escrow Shares shall be evidenced
by certificates issued in the name of each Stockholder. All of the Escrow Shares
shall be deemed to be issued and outstanding capital stock of Broadbase.

     (b) Dividends. If Broadbase declares any cash dividends, dividends payable
in other property or other distributions of any kind with respect to Escrow
Shares held by the Escrow Agent, Broadbase will issue such distributions
directly to the Stockholders. Tax-free (pursuant to Section 305(a) of the Code)
stock dividends declared on the Escrow Shares during the Escrow Period in order
to effect a stock split of Broadbase common stock ("Additional Escrow Shares")
will be delivered promptly to the Escrow Agent, held in escrow and distributed
to the Stockholders in the same manner and in the same proportions as the Escrow
Shares. For all purposes of this Agreement, the Additional Escrow Shares will be
treated the same as the Escrow Shares. Unless and until the Escrow Agent
receives certificates representing Additional Escrow Shares, the Escrow Agent
may assume, without inquiry, that no Additional Escrow Shares have been, or are
required to be, issued and that the stock certificates that the Escrow Agent
possesses represent all of the Escrow Shares.

     (c) Voting and Other Rights of Ownership. While the Escrow Shares remain in
the possession of the Escrow Agent, each Stockholder beneficially owning Escrow
Shares will retain and will be able to exercise with respect to such Escrow
Shares: (i) voting rights, and (ii) all other incidents of ownership of such
Escrow Shares which are not inconsistent with the terms of this Agreement.
Subject to the rights of Broadbase under the Merger Agreement and this
Agreement, all beneficial interest in the Escrow Shares shall be the property of
the Stockholders from and after the Closing, and Broadbase shall have no
interest therein. Each of the Stockholders shall be obligated for all federal,
state or local taxes applicable to such Stockholder's interest in the Escrow
Shares.

     (d) No Transfers or Encumbrances. Prior to the Release Date, as defined in
Section 2.3(a), (or the release of the Escrow Shares, with respect to shares
held with respect to pending Claims pursuant to
                                       E-2
<PAGE>   297

Section 2.3(b) of this Agreement), Stockholders may not sell, assign, transfer,
pledge or otherwise place any encumbrance on, any Escrow Shares or any
beneficial interest therein, except: (i) transfers made for estate planning
purposes, and (ii) transfers by operation of law or laws of descent and
distribution. In the case of any permitted transfer, the transferee will be
subject to all terms and provisions of this Agreement. Also, prior to the
Release Date (or the release of the Escrow Shares, with respect to shares held
with respect to pending Claims pursuant to Section 2.3(b) of this Agreement), no
Escrow Shares nor any beneficial interest therein shall be taken or reached by
any legal or equitable process in satisfaction of any debt or other liability of
a Stockholder, except to satisfy such Stockholder's obligations under Article 12
of the Merger Agreement. The Escrow Agent shall have no responsibility for
determining or enforcing compliance with this paragraph, other than by retaining
possession of the Escrow Shares.

     (e) Right of Escrow Agent to Transfer Shares. Notwithstanding the other
provisions of this Section 2.1, the Escrow Agent shall have the power to effect
any transfer of Escrow Shares required by this Agreement or necessary for
administrative purposes. Broadbase shall cooperate with the Escrow Agent in
promptly issuing, or causing its transfer agent to promptly issue, such stock
certificates as shall be required to effect such transfers.

     2.2  Escrow Ledger. The Escrow Agent shall create and maintain a written
record of each Stockholder's interest in the Escrow Shares, in substantially the
form attached as Exhibit B (the "Escrow Ledger"). The Escrow Agent shall adjust
the Escrow Ledger to reflect changes in each Stockholder's interests in the
Escrow Shares. This duty will continue until the Escrow Agent is required to
deliver each Stockholder's Escrow Shares pursuant to Section 2.3. Absent
manifest error, all of the Escrow Agent's determinations as to the Escrow Ledger
shall be binding and conclusive on all parties to this Agreement. Adjustments to
the Escrow Ledger shall include, but are not limited to, the following:

          (a) Adjustments for Capital Changes. The Escrow Agent shall adjust the
     Escrow Ledger to reflect the Escrow Agent's receipt of Additional Escrow
     Shares pursuant to Section 2.1(b).

          (b) Adjustments for Claims. The Escrow Agent shall deduct Escrow
     Shares that become subject to pending Contested Claims (as defined in
     Section 4.3) of Broadbase or other Indemnified Persons from column 6 of
     each Stockholder's account in the Escrow Ledger and add such Escrow Shares
     to column 5 of each Stockholder's account. The Escrow Agent shall deduct
     Escrow Shares that are charged and allocated to each Stockholder's account
     pursuant to Article 4 in satisfaction of Claims (as defined in Section 3.1)
     by Broadbase or other Indemnified Persons from columns 2-6, as appropriate.

     2.3  Release of Escrow Shares to Stockholders.

     (a) Release of Escrow Shares Generally. On the first anniversary of the
Closing Date (the "Release Date"), in accordance with Section 2.3(c), the Escrow
Agent shall certify the Escrow Share balances reflected in the Escrow Ledger as
of that date and direct the Exchange Agent to release the appropriate number of
Escrow Shares to each Stockholder as designated in column 6 of the Escrow
Ledger, which shall equal such Stockholder's original Escrow Shares plus any
Additional Escrow Shares issued to such Stockholder, minus: (i) any Escrow
Shares attributable to such Stockholder that were returned to Broadbase in
accordance with Article 4 in satisfaction of a Claim(s) by Broadbase or another
Indemnified Person(s), and (ii) any Escrow Shares attributable to such
Stockholder that are subject to pending Claims of Broadbase or other Indemnified
Persons, to be held pursuant to Section 2.3(b). The Escrow Agent will direct the
Exchange Agent to remove the legend described in Section 1.1(c) from all Escrow
Shares distributed by it.

     (b) Escrow Shares Subject to Pending Claims.

     (i) Upon the Release Date and thereafter, the Escrow Agent shall continue
to hold any Escrow Shares that are subject to pending Claims until the ten (10)
business day period in Section 4.2 expires. At that time, the Escrow Agent
shall, as appropriate, either instruct the Exchange Agent to distribute the
Escrow Shares subject to such Claims pursuant to Section 4.2, or continue to
hold the Escrow Shares subject to such Claims pursuant to Section 2.3(b)(ii).
                                       E-3
<PAGE>   298

     (ii) Upon the Release Date and thereafter, the Escrow Agent shall continue
to hold any Escrow Shares that are subject to Contested Claims of Broadbase or
other Indemnified Persons, as designated in column 5 of the Escrow Ledger, until
the Escrow Agent receives written notice of resolution of each specific Claim
pursuant to Section 4.3(c). After the Escrow Agent receives such notice, in
accordance with Section 2.3(c), the Escrow Agent shall: (a) either deliver or
instruct the Exchange Agent to deliver to each Stockholder the number of Escrow
Shares, if any, due to each Stockholder in accordance with the resolution of the
Claim; (b) if applicable, charge and allocate Escrow Shares against each
Stockholder's account in satisfaction of the resolution of the Claim and either
return or instruct the Exchange Agent to return such Escrow Shares back to
Broadbase; and (c) notify the Representative in writing of any deduction of
Escrow Shares as promptly as reasonably practicable. The Escrow Agent shall make
the appropriate entries in the Escrow Ledger.

     (c) Procedure for Release and Delivery. Subject to Section 2.3(b)(i),
within five (5) days after the Release Date (or with respect to Escrow Shares
held pursuant to Section 2.3(b)(ii), within five (5) days after the Escrow
Agent's receipt of written notice of a resolution of a Claim pursuant to Section
4.3(c)), the Escrow Agent shall instruct the Exchange Agent to deliver to each
Stockholder by mailing (by registered or certified mail, return receipt
requested) to the address set forth opposite each Stockholder's name on the
Escrow Ledger (or such other address as provided in writing by the
Representative to the Escrow Agent) the number of Escrow Shares determined in
accordance with Section 2.3(a). No fractional Escrow Shares will be delivered.
Broadbase shall have provided to the Escrow Agent prior to the expiration of the
Escrow Period, and the Escrow Agent shall distribute to each Stockholder at the
time Escrow Shares, if any, are distributed to each Stockholder, cash in lieu of
any fractions of Escrow Shares in an amount equal to the product of such
fraction multiplied by the value of an Escrow Share as determined in accordance
with Section 4.5. The Escrow Agent need not invest cash on hand pending
distribution.

     3. Claims

     3.1  "Claim" Defined. As used herein, the term "Claim" means a claim for
indemnification under Article 12 of the Merger Agreement made by Broadbase or by
any other Indemnified Person.

     3.2  Notice of Claim.

     (a) When a Notice of Claim is Required. An officer of Broadbase shall
execute and deliver written notice of a Claim (a "Notice of Claim") to the
Representative and the Escrow Agent as promptly as reasonably practicable, and
in no event after the Release Date, upon Broadbase's discovery of any Damages
directly or indirectly arising out of or resulting from:

          (i) any misrepresentation or breach of or default in connection with
     any of the representations, warranties, agreements and covenants given or
     made by Servicesoft in the Merger Agreement or any certificate, document or
     instrument delivered by or on behalf of Servicesoft pursuant to the Merger
     Agreement;

          (ii) any Excess Expenses;

          (iii) any order or proceeding brought by any third person against
     Broadbase and/or any Indemnified Person that is based upon or includes
     assertions that would, if true, constitute a misrepresentation, breach of
     or default in connection with any of the representations, warranties,
     agreements and covenants given or made by Servicesoft in the Merger
     Agreement or any certificate, document or instrument delivered by or on
     behalf of Servicesoft pursuant to the Merger Agreement (a "Third Party
     Proceeding"); or

          (iv) any failure of a Servicesoft Stockholder to have good, valid and
     marketable title to the issued and outstanding Servicesoft common stock
     disclosed on Item 4.3(a) of the Servicesoft Disclosure Letter as being held
     by such Servicesoft Stockholder;

     (b) Failure to Provide Notice of Claim. Failure to provide such notice in a
timely manner shall not reduce Broadbase's indemnification rights or the
indemnification obligations of the Stockholders in this
                                       E-4
<PAGE>   299

Agreement and under the Merger Agreement, unless the failure to provide such
timely notice impairs the indemnifying party's ability to defend the Claim, and
then only to the extent of such impairment, and except as set forth in Section
3.2(c) below.

     (c) All claims for Damages under Article 12 of the Merger Agreement must be
initiated prior to the expiration of the Escrow Period.

     3.3  Contents of Each Notice of Claim. Each Notice of Claim given by
Broadbase pursuant to Section 3.2 shall be set forth in writing and shall
contain the following information to the extent it is reasonably available to
Broadbase:

          (a) Statement of Damages. The statement of Damages shall include
     Broadbase's good faith estimate of the reasonably foreseeable maximum
     amount of the alleged Damages that will ultimately be incurred by Broadbase
     and/or any other Indemnified Person in connection with such Claim,
     including, without limitation, any Damages from a potential Third Party
     Proceeding.

          (b) Statement of Basis for Damages. The statement of basis for Damages
     shall include: (i) a brief description of the facts, circumstances or
     events giving rise to the alleged Damages based on Broadbase's or any other
     affected Indemnified Person's good faith belief, and (ii) if applicable,
     specific references to the provisions of the Merger Agreement alleged to
     have been breached.

     3.4  Requirement of Resolution of Claims. The Escrow Agent shall not act
regarding any of the Escrow Shares held pursuant to a Notice of Claim until such
Notice of Claim has been resolved in accordance with Article 4 and, in the case
of a Contested Claim, it receives appropriate notice pursuant to Section 4.3(c).

     4. Resolution of Claims

     Any Notice of Claim received by the Representative and the Escrow Agent
pursuant to Article 3 shall be resolved as follows:

     4.1  Third Party Proceedings. Broadbase shall have the right, at the
Stockholders' expense (to be paid in Escrow Shares subject to the provisions of
Section 12 of the Merger Agreement), to select counsel in connection with
conducting the defense or handling each Third Party Proceeding and defend or
handle such Third Party Proceeding in such manner as Broadbase may deem
reasonably appropriate (including, without limitation, consent to an entry of
judgement or settlement of such Third Party Proceeding); provided, however, that
Broadbase shall keep the Representative timely apprised of the status of such
Third Party Proceeding. The reasonable costs and expenses incurred by Broadbase
in connection with such defense (including, but not limited to, reasonable
attorneys' fees, other professionals' and experts' fees and court or arbitration
costs) shall be included in the Damages for which Broadbase may seek indemnity
pursuant to a Claim made by Broadbase or an Indemnified Person hereunder. The
Representative and the Stockholders shall cooperate with Broadbase and shall be
entitled to participate in the defense or handling of the Third Party Proceeding
with their own counsel and at their own expense.

     4.2  Uncontested Claims. If, within ten (10) business days after the Escrow
Agent and the Representative receive a Notice of Claim, the Representative does
not contest such Notice of Claim (an "Uncontested Claim") in a written notice
delivered to the Escrow Agent pursuant to Section 4.3, then the Escrow Agent
shall: (a) immediately charge and allocate against each Stockholder's accounts
in the Escrow Ledger the number of Escrow Shares required, pursuant to Section
4.5, to satisfy the amount of Damages specified in such Notice of Claim (reduced
by any recovery to date under policies of insurance not reflected in the Notice
of Claim); (b) update the Escrow Ledger to reflect the effect of the deduction
pursuant to Section 2.2(b); and (c) notify the Representative in writing of the
deduction of Escrow Shares as promptly as reasonably practicable. The number of
Escrow Shares deducted hereunder shall be charged to and allocated among the
Stockholders pro rata according to each Stockholder's percentage share, as set
forth in column 4 of the Escrow Ledger, except as otherwise provided for in
Section 12.2 of the Merger Agreement.

                                       E-5
<PAGE>   300

     4.3  Contested Claims. If Broadbase and the Escrow Agent receive a written
notice contesting all, or a portion of, a Notice of Claim within the ten (10)
business day period described in Section 4.2 (a "Contested Claim"), then the
parties will work together in good faith to resolve their dispute for up to
thirty (30) days. If the Contested Claim is not resolved in such thirty (30) day
period, then: (a) such Contested Claim shall be resolved by binding arbitration
in accordance with Section 13.10 of the Merger Agreement, and (b) the Escrow
Agent shall continue to hold the number of Escrow Shares sufficient, pursuant to
Section 4.5, to satisfy the maximum potential award to all Indemnified Persons
under such Claim. Any portion of the Notice of Claim that is not contested by
the Representative in accordance with the foregoing provisions of this Section
4.3 shall be resolved as an Uncontested Claim in accordance with Section 4.2. In
addition to the provisions of Section 13.10 of the Merger Agreement, resolution
of Contested Claims shall be subject to the following additional provisions:

          (a) Award.

          (i) Upon the conclusion of any arbitration proceedings hereunder, the
     arbitrator shall render findings of fact and conclusions of law and a final
     written arbitration award setting forth the basis and reasons for any
     decision reached (the "Final Award") and shall deliver such documents to
     the Escrow Agent, the Representative and Broadbase. The Final Award shall
     constitute a conclusive determination of all issues in question, binding
     upon the Representative, the Stockholders and Broadbase, and shall not be
     contested by the Representative, the Stockholders or Broadbase.

          (ii) To the extent that the Final Award determines that Broadbase or
     any other Indemnified Person has actually incurred Damages in connection
     with the Contested Claim through the date of the Final Award ("Incurred
     Damages"), the Final Award will set forth and award to Broadbase the amount
     of such damages, reduced by any recovery under policies of insurance to
     date that were not specified in the Notice of Claim. In addition, the Final
     Award will set forth an additional amount of Damages equal to the
     reasonably foreseeable amount of alleged Damages that the arbitrator
     determines (based on the evidence submitted by the parties in the
     arbitration) are reasonably likely to be incurred by Broadbase and any
     other Indemnified Person as a result of the facts giving rise to the
     Contested Claim ("Estimated Damages"), which amount of Estimated Damages
     may, without limitation, include the amount of damages claimed by a third
     party in an action brought against any Indemnified Person based on alleged
     facts which, if true, would give rise to Damages. The Escrow Agent will
     continue to hold Escrow Shares representing the Estimated Damages, in
     accordance with Section 4.5, in escrow, including, if appropriate, beyond
     the expiration of the Escrow Period, until and to the extent that: (A) the
     arbitrator deems that Broadbase has actually incurred such Estimated
     Damages, reduced by any recovery under policies of insurance to date that
     were not specified in the Notice of Claim; (B) the arbitrator deems that
     Broadbase will not actually incur any additional Estimated Damages; or (C)
     the parties come to a written settlement agreement pursuant to Section 4.4.
     Both Incurred Damages and Estimated Damages owed to Indemnified Persons are
     deemed to be Damages for purposes of this Agreement. Upon issuance and
     delivery of the Final Award pursuant to Section 4.3(a)(i), and subject to
     receipt by the Escrow Agent of a written notice of resolution of the Claim
     pursuant to Section 4.3(c), Broadbase will immediately be entitled to
     recover the amount of any Incurred Damages awarded to Broadbase under such
     Final Award.

          (b) Timing. The Representative, Broadbase and the arbitrator shall
     conclude each arbitration pursuant to this Section 4.3 as promptly as
     practicable. Time is of the essence with regards to all aspects of this
     Agreement.

          (c) Notice of Resolution of Claim. The Escrow Agent shall not deliver
     Escrow Shares held pursuant to a Contested Claim until the Escrow Agent
     receives appropriate notice. Such notice must consist of: (i) written
     notice of the resolution of such Claim executed by both the Representative
     and Broadbase; (ii) a written settlement agreement pursuant to Section 4.4;
     (iii) delivery to the Escrow Agent of an appropriate final non-appealable
     order by a court of competent jurisdiction; or (iv) delivery to the Escrow
     Agent of a copy of the Final Award of an arbitrator or court. The Escrow
     Agent shall act on such notice without further inquiry in accordance with
     Sections 2.3(b) and (c).

                                       E-6
<PAGE>   301

          (d) Multiplicity of Claims. The assertion of any single Claim for
     indemnification hereunder will not bar Broadbase from asserting other
     Claims hereunder.

     4.4  Settled Claims. If a Claim (including a Contested Claim) is settled by
a written settlement agreement executed by the Representative and Broadbase,
then the Representative and Broadbase shall promptly deliver such written
settlement agreement to the Escrow Agent with written instructions on the
appropriate charges or adjustments to be made to the Escrow Ledger, and the
Escrow Agent shall promptly release and/or return the Escrow Shares subject to
such claim in accordance with Sections 2.3(b) and 2.3(c). Any settlement which
is effected without the consent of the Representative, which consent shall not
be unreasonably withheld or delayed, shall not be determinative of the amount of
Damages for which indemnification may be sought.

     4.5  Determination of Number of Escrow Shares for Claims. Unless a specific
number of Escrow Shares is specified, or unless any claim asserts that a
different allocation should be made pursuant to Section 12.2 of the Merger
Agreement, any amount owed to Broadbase under this Agreement will be immediately
payable to Broadbase, subject to Section 4.3(c), by deducting pro rata from each
Stockholder's account in the Escrow Ledger the number of Escrow Shares equal to:
(a) the Damages for that Claim, divided by, (b) the average of the closing
prices of Broadbase common stock for the ten (10) trading days ending 2 trading
days prior to the Closing (subject to adjustment for changes in Broadbase
capital stock as set forth in a certificate of Broadbase delivered to the Escrow
Agent).

     4.6  Election of Remedies. Broadbase may institute Claims against the
Escrow Shares and in satisfaction thereof may elect to have such Escrow Shares
deducted from the Escrow Ledger, after any notice to the Representative required
hereunder, without making any other claims directly against the Stockholders and
without rescinding or attempting to rescind the transactions consummated
pursuant to the Merger Agreement. Broadbase need not exhaust any other remedies
that may be available to it but may proceed directly in accordance with the
provisions of this Agreement.

     5. The Escrow Agent

     5.1  Limitation of Escrow Agent's Liability/Responsibility. In performing
any of its duties under this Escrow Agreement, the Escrow Agent shall not be
liable to any party for damages, losses or expenses, except in the event of
gross negligence or willful misconduct on its part. In no event shall the Escrow
Agent be liable for punitive, consequential or incidental damages. The Escrow
Agent shall not incur any such liability for any action taken or omitted in
reliance upon any instrument, including any written statement or affidavit
provided for in this Escrow Agreement that the Escrow Agent shall in good faith
believe to be genuine; nor will the Escrow Agent be liable or responsible for
forgeries, fraud, impersonations or determining the scope of any agent's
authority. In addition, the Escrow Agent may consult with legal counsel of its
choice in connection with its duties under this Escrow Agreement and shall be
fully protected in any act taken, suffered or permitted by it in good faith in
accordance with the advice of counsel. The Escrow Agent is not responsible for
determining and verifying the authority of any person acting or purporting to
act on behalf of any party to this Escrow Agreement. The Escrow Agent undertakes
to perform such duties as are specifically set forth in this Escrow Agreement,
and the Escrow Agent shall not be liable except for the performance of such
duties as are specifically set forth in this Escrow Agreement. No implied
covenants or obligations shall be read into this Escrow Agreement against the
Escrow Agent.

     5.2  Indemnification of the Escrow Agent.

     (a) For the purposes of this Section 5.2, references to the Escrow Agent
shall include the Escrow Agent's officers, directors, employees, counsel and
agents.

     (b) Each party to this Agreement other than the Escrow Agent and the
Representative in his capacity as the Representative (each an "Indemnifying
Party" and together the "Indemnifying Parties") will severally reimburse,
indemnify and hold harmless the Escrow Agent from and against any damage,
liability or loss suffered, incurred by, or asserted against the Escrow Agent
(including amounts paid in settlement of any action, suit, proceeding, or claim
brought or threatened to be brought and including
                                       E-7
<PAGE>   302

reasonable expenses of legal counsel, collectively, "Loss") arising out of, in
connection with or based upon any act or omission by the Escrow Agent relating
in any way to this Agreement or the Escrow Agent's services hereunder. This
indemnity will exclude any indemnification for any Loss arising in whole or in
part, directly or indirectly, from any fraud, gross negligence or willful
misconduct on the Escrow Agent's part. Anything in this Agreement to the
contrary notwithstanding, in no event will the Escrow Agent be liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits) suffered by another party to this
Agreement or by any Stockholder, even if the Escrow Agent has been advised of
the likelihood of such loss or damage and regardless of the form of action. The
Escrow Agent's right to indemnification hereunder will survive the Escrow
Agent's resignation or removal as the Escrow Agent and will survive the
termination of this Agreement by lapse of time or otherwise.

     (c) Each Indemnifying Party may participate at its own expense in the
defense of any claim or action that may be asserted against the Escrow Agent
related to this Agreement, and if the Indemnifying Parties so elect, the
Indemnifying Parties may assume the defense of such claim or action; provided,
however, that, if there exists a conflict of interest that would make it
inappropriate, in the sole discretion of the Escrow Agent, for the same counsel
to represent both Escrow Agent and the Indemnifying Parties, the Escrow Agent's
retention of separate counsel will be reimbursable as provided in Section
5.2(b).

     (d) The Escrow Agent will notify each Indemnifying Party by letter, or by
telephone or telecopy confirmed by letter, of any receipt by Escrow Agent of a
written assertion of a claim against the Escrow Agent arising out of this
Agreement, or any action commenced against the Escrow Agent arising out of this
Agreement, within five (5) business days after the Escrow Agent's receipt of
written notice of such claim. However, the Escrow Agent's failure to so notify
each Indemnifying Party will not operate in any manner whatsoever to relieve an
Indemnifying Party from any liability that it may have to the Escrow Agent under
this Section 5.2 or otherwise unless such failure by the Escrow Agent to give
such notice materially prejudices such Indemnifying Party.

     5.3  Compensation and Expenses of Escrow Agent. All fees and expenses of
the Escrow Agent incurred in the ordinary course of performing its
responsibilities hereunder shall be paid by Broadbase upon receipt of a written
invoice by Escrow Agent in accordance with Exhibit C attached hereto.

     5.4  Resolution of Conflicting Demands. In the event conflicting demands
are made or conflicting notices are served upon the Escrow Agent with respect to
the Escrow Shares or the Escrow Ledger, the Escrow Agent shall have the right,
at the Escrow Agent's election, to either: (a) give written notice to the other
parties to this Agreement that it has received conflicting instructions from
Broadbase and the Representative and is refraining from taking action until it
receives instructions consented to in writing by both Broadbase and the
Representative, or (b) resign so that a successor escrow agent can be appointed
pursuant to Section 5.5. In the further event that the Escrow Agent gives
written notice under "(a)" above and does not receive instructions consented to
in writing by both Broadbase and the Representative within thirty (30) calendar
days, then the Escrow Agent may file a suit in interpleader and obtain an order
from a court of competent jurisdiction located in Wilmington, Delaware,
requiring the parties to interplead and litigate in such court their several
claims and rights among themselves. In this case, the Escrow Agent shall thereby
be fully released and discharged from all further obligations imposed upon it
under this Agreement with respect to the matters that are the subject of such
interpleader suit, and Broadbase shall pay the Escrow Agent all costs, expenses
and reasonable attorneys' fees expended or incurred by the Escrow Agent pursuant
to the exercise of Escrow Agent's rights under this paragraph.

     5.5  Successor Escrow Agent.

     (a) In the event the Escrow Agent becomes unavailable or unwilling to
continue in its capacity as Escrow Agent hereunder, the Escrow Agent may resign
and be discharged from its duties hereunder by giving notice of resignation to
the parties to this Agreement, specifying a date not less than thirty (30) days
following such notice date of when such resignation shall take effect and
refunding to Broadbase any prepaid but unearned fees previously paid by
Broadbase to the Escrow Agent hereunder. Broadbase shall designate a successor
Escrow Agent reasonably satisfactory to the Representative prior to the
expiration of
                                       E-8
<PAGE>   303

such thirty (30) day period by giving written notice to the Escrow Agent and the
Representative. If no successor escrow agent is named by Broadbase, then the
Escrow Agent may apply to a court of competent jurisdiction for the appointment
of a successor Escrow Agent. In either case, the Escrow Agent shall promptly
transfer the Escrow Shares and Escrow Ledger to the designated successor Escrow
Agent.

     (b) In the event Escrow Agent is merged with, acquired or otherwise
combined with another entity, or Escrow Agent transfers all or substantially all
of its corporate trust business (including the escrow contemplated by this
Agreement) to another institution, the successor as a result of such transaction
will be the Escrow Agent hereunder without any further action by the parties
hereto.

     6. The Representative

     6.1  Duties as Provided in Merger Agreement. From and after the deposit of
the Escrow Shares as provided in Article 1, the Stockholders shall be
represented by the Representative, or, upon written notice to the Escrow Agent,
by his successor appointed in accordance with Section 12.6(d) of the Merger
Agreement. The Representative (a) shall have the duties and obligations set
forth in Section 12.6(a) of the Merger Agreement, (b) shall not be liable to the
Stockholders in connection with the performance of his duties and obligations
under this Agreement except as set forth in Section 12.6(b) of the Merger
Agreement, and (c) shall be indemnified by the Stockholders in connection with
the performance of the his duties and obligations under this Agreement as
provided in Section 12.6(c) of the Merger Agreement.

     6.2  No Compensation; Reimbursement for Expenses. Except as stated in
Section 12.6(c) of the Merger Agreement and in this paragraph, the
Representative shall not be entitled to receive any compensation for his
services in connection with this Agreement. Any out-of-pocket costs and expenses
reasonably incurred by the Representative in connection with actions taken
pursuant to the terms of this Agreement shall be paid by the Stockholders in
proportion to their percentage interest in the aggregate Escrow Shares set forth
in column 4 of the Escrow Ledger promptly upon the Representative's written
request to the Stockholders and, at the Representative's option, may be taken by
the Representative from the Escrow Shares reflected in the Escrow Ledger after
the final resolution of all Claims made under this Agreement.

     6.3  Tax Reporting Documentation. The Representative agrees to use all
reasonable efforts to obtain for the Escrow Agent certified tax identification
numbers for each of the Stockholders consisting of appropriate Forms W-9 (or
Forms W-8, in the case of non-U.S. persons) and other forms and documents that
the Escrow Agent may reasonably request (collectively, "Tax Reporting
Documentation") to the Escrow Agent within 30 days after the date of such
request. The parties hereto understand that, if such Tax Reporting Documentation
is not so certified to the Escrow Agent, the Escrow Agent may be required by the
Code, as it may be amended from time to time, to withhold a portion of the
interest earned on the investment of monies or other property held by the Escrow
Agent pursuant to this Agreement.

     7. Miscellaneous

     7.1  Term of Escrow Agreement. This Escrow Agreement shall terminate upon
the distribution by the Escrow Agent of all Escrow Shares and other property
held in escrow.

     7.2  Entire Agreement. This Agreement, the Merger Agreement and the
exhibits hereto and thereto constitute the entire understanding and agreement of
the parties with respect to the subject matter of this Agreement and supersede
all prior agreements or understandings, written or oral, between the parties
with respect to the subject matter hereof. As between the Escrow Agent and the
other parties hereto, all such parties agree that the Escrow Agent's duties are
defined only in this Agreement, any contrary provisions of the Merger Agreement
notwithstanding.

     7.3  Further Assurances. Each party agrees to cooperate fully with the
other parties and to execute such further instruments, documents and agreements
and to give such further written assurances, as may be reasonably requested by
any other party to better evidence and reflect the transactions described herein
and contemplated hereby and to carry into effect the intents and purposes of
this Agreement.

                                       E-9
<PAGE>   304

     7.4  Assignment; Binding Nature. Broadbase may not assign all or any of its
rights and obligations hereunder without the prior written consent of the Escrow
Agent and the Representative, which consent shall not be unreasonably withheld.
Except for assignments in connection with permitted transfers of Escrow Shares
under Section 2.1(d) of this Agreement, neither the Stockholders, nor the
Representative on their behalf, may assign any of rights or obligations of the
Stockholders hereunder, nor may their rights or obligations be assigned by
operation of law, without the prior written consent of Broadbase. This Agreement
and shall be binding upon, and inure to the benefit of, the parties hereto and
their respective successors and permitted assigns.

     7.5  Absence of Third Party Beneficiary Rights. No provisions of this
Escrow Agreement are intended, nor shall be interpreted, to provide or create
any third party beneficiary rights or any other rights of any kind in any
client, customer, affiliate, Stockholder, partner of any party hereto or any
other person or entity unless specifically provided otherwise herein, and,
except as so provided, all provisions hereof shall be solely between the parties
to this Escrow Agreement.

     7.6  Construction of Agreement. This Agreement has been negotiated by the
respective parties hereto and their attorneys and have been reviewed by each
party hereto. Accordingly, no ambiguity in the language of this Agreement will
be construed for or against either party.

     7.7  Section Headings. A reference to a section, article or exhibit will
mean a section in, article in or exhibit to this Agreement unless otherwise
explicitly set forth. The titles and headings herein are for reference purposes
only and will not in any manner limit the construction of this Agreement, which
will be considered as a whole.

     7.8  Amendment. This Agreement may be amended by the written agreement of
Broadbase, the Escrow Agent and the Representative; provided, however, that, if
the Escrow Agent does not agree to an amendment agreed upon by Broadbase and the
Representative, then the Escrow Agent shall resign and a successor Escrow Agent
shall be appointed in accordance with the provisions of Section 5.5. No
amendment of the Merger Agreement shall increase or alter the Escrow Agent's
duties, responsibilities or liability hereunder without the Escrow Agent's
written agreement.

     7.9  Waiver. No waiver by any party hereto of any condition or of any
breach of any provision of this Agreement shall be effective unless it is set
forth in a writing signed by such party. No waiver by any party of any such
condition or breach, in any one instance, shall be deemed to be a further or
continuing waiver of any such condition or breach or a waiver of any other
condition or breach of any other provision contained herein. The failure of any
party to enforce any of the provisions hereof will not be construed to be a
waiver of the right of such party thereafter to enforce such provisions.

     7.10  Severability. If any provision of this Agreement or its application
will for any reason and to any extent be invalid or unenforceable, the remainder
of this Agreement and application of such provision to other persons or
circumstances will be interpreted so as to effect the intent of the parties
hereto. The parties will replace such void or unenforceable provision of this
Agreement with a valid and enforceable provision that will achieve, to the
extent possible, the economic, business and other purposes of the void or
unenforceable provision.

     7.11  Governing Law. The validity of this Agreement the construction of its
terms, and the interpretation and enforcement of the rights and duties of the
parties of this Agreement will be exclusively governed by and construed in
accordance with the internal laws of the State of Delaware, as applied to
agreements entered into solely between residents of and to be performed entirely
in the State of Delaware, without reference to that body of law relating to
conflicts of law or choice of law.

     7.12  Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy will not preclude the exercise of any other.

September 18, 2000

CONFIDENTIAL
The Board of Directors
Broadbase Software, Inc.
181 Constitution Drive
Menlo Park, CA 94025

Members of the Board:

     You have requested our opinion as to the fairness, from a financial point
of view, ("Opinion") to Broadbase Software, Inc., a Delaware corporation (the
"Company"), of the Conversion Ratio set forth in the proposed Agreement and Plan
of Merger, anticipated to be dated as of September 18, 2000 (the "Agreement"),
by and among the Company, Soldier Acquisition Corp., a Delaware corporation and
wholly owned subsidiary of the Company ("Merger Sub"), and Servicesoft, Inc., a
Delaware corporation (the "Target"). Capitalized terms used herein shall have
the meanings used in the Agreement, unless otherwise defined herein.

     Pursuant to the Agreement, the Conversion Ratio is defined such that each
outstanding share of common stock of the Target (the "Target Common Stock"),
will be converted into 1.440 shares of common stock of the Company (the "Company
Common Stock"). Options and warrants of Target will be converted into options
and warrants of the Company based on the Conversion Ratio. The transaction is
intended to qualify as a reorganization under the provisions of Section 368(a)
of the Internal Revenue Code and to be accounted for as a purchase for financial
accounting purposes. The terms and conditions of the Merger are set forth more
fully in the Agreement.

     Dain Rauscher Wessels, a division of Dain Rauscher Incorporated ("Dain
Rauscher Wessels"), as part of its investment banking services, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, corporate restructurings, underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. As financial advisor to the Company
in connection with the Merger, it has been requested that we provide this
Opinion, and we will receive a fee for providing this Opinion. Our fee for this
Opinion is not contingent upon consummation of the Merger. Dain Rauscher Wessels
will receive an additional advisory fee contingent upon consummation of the
Merger. In addition, the Company has agreed to indemnify us for certain
liabilities arising out of our engagement. In the ordinary course of business,
Dain Rauscher Wessels acts as a market maker and broker in the publicly traded
securities of the Company and receives customary compensation in connection
therewith, and also actively trades securities of the Company for its own
account and for the accounts of its customers and, accordingly, may at any time
hold a long or short position in such securities. Dain Rauscher Wessels has also
acted as a managing underwriter for the initial public offering and a follow-on
offering of Company Common Stock and provides research coverage for Company
Common Stock.

     In connection with our review of the Merger, and in arriving at our
opinion, we have: (i) reviewed and analyzed the financial terms of the draft
Agreement dated September 15, 2000; (ii) reviewed and analyzed certain publicly
available financial and other data with respect to the Company and Target and
certain other historical operating data relating to the Company and Target made
available to us from published sources and from the internal records of the
Company and Target; (iii) conducted discussions with members of the senior
management of the Target with respect to the business prospects and financial
outlook of the Target; (iv) conducted discussions with members of the senior
management of the Company with respect to the business prospects and financial
outlook of the Company and the combined entity; (v) received and reviewed
financial forecasts prepared by the Target's management and the Company's
management on the potential future performance of Target, both as a stand alone
entity and as a part of the Company; (vi) analyzed the impact on the Company's
earnings per share; (vii) reviewed the

reported prices and trading activity for the Company Common Stock; (viii)
compared the financial performance of the Company and the Target and the prices
of the Company Common Stock and the implied valuation of Target with that of
certain other comparable publicly-traded companies and their securities; (ix)
reviewed the financial terms, to the extent publicly available, of certain
comparable merger transactions; and (x) compared the relative contribution to
certain income statement items of each company with their pro-forma ownership in
the combined company. In addition, we have conducted such other analyses and
examinations and considered such other financial, economic and market criteria
as we have deemed necessary in arriving at our opinion.

     With respect to the data and discussions relating to the business prospects
and financial outlook of the Company and the Target, upon advice of the Company
we have assumed that such data has been reasonably prepared on a basis
reflecting the best currently available estimates and judgments of the
management of the Company and Target as to the future financial performance of
the Company and the Target, and that the Company and the Target will perform
substantially in accordance with such financial data and estimates. We express
no opinion as to such financial data and estimates or the assumptions on which
they were based. We were not provided long-term projections on Target and thus,
we did not prepare a discounted cash flow analysis for purposes of this opinion.

     In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of the financial, legal, tax, operating and other information
provided to us by the Company and the Target (including, without limitation, the
financial statements and related notes thereto of the Company and the Target),
and have not assumed responsibility for independently verifying and have not
independently verified such information. We have not assumed any responsibility
to perform, and have not performed, an independent evaluation or appraisal of
any of the respective assets or liabilities of the Company or the Target, and we
have not been furnished with any such valuations or appraisals. In addition, we
have not assumed any obligation to conduct, and have not conducted, any physical
inspection of the property or facilities of the Company or the Target.
Additionally, we have not been asked and did not consider the possible effects
of any litigation or other legal claims. Further, we have assumed that the
Company will account for the Merger as a purchase transaction under generally
accepted accounting principles and will qualify as a reorganization for U.S.
federal income tax purposes.

     Our opinion speaks only as of the date hereof, is based on the conditions
as they exist and information which we have been supplied as of the date hereof,
and is without regard to any market, economic, financial, legal or other
circumstances or event of any kind or nature which may exist or occur after such
date. We have not undertaken to reaffirm or revise this Opinion or otherwise
comment upon events occurring after the date hereof and do not have any
obligations to update, revise or reaffirm this Opinion. Our advisory services
and the opinion expressed herein are provided for the information and assistance
of the Board of Directors of the Company in connection with its consideration of
the transactions contemplated by the Agreement and is not intended to be and
does not constitute a recommendation to any stockholder of the Company. Further,
our opinion does not address the merits of the underlying decision by the
Company to engage in such transaction. This Opinion shall not be published or
otherwise used, nor shall any public references to us be made without our prior
written approval, except that the Opinion may be included in full in the
prospectus/proxy statement distributed to the Company's shareholders in
connection with this transaction.

     We are not expressing any opinion herein as to the prices at which the
Company Common Stock has traded or will trade following the announcement or
consummation of the Merger.

     Our opinion relates solely to the Conversion Ratio. We have not reviewed,
nor does our opinion in any way address, other Merger terms or arrangements,
including without limitation the financial or other terms

of any employment or non-competition agreement with Target management, any
interim financing with Target or any break-up or termination fee.

     Based on our experience as investment bankers and subject to the foregoing,
including the various assumptions and limitations set forth herein, it is our
opinion that, as of the date hereof, the Conversion Ratio is fair, from a
financial point of view, to the Company.

                                          Very truly yours,

                                          DAIN RAUSCHER WESSELS,

                   [LETTERHEAD OF MORGAN STANLEY DEAN WITTER]

September 15, 2000

Board of Directors
Servicesoft, Inc.
2 Apple Hill Drive
Natick, MA 01760

Members of the Board:

     We understand that Servicesoft, Inc. ("Servicesoft" or the "Company"),
Broadbase Software, Inc. ("Broadbase") and Soldier Acquisition Corp., a
wholly-owned subsidiary of Broadbase ("Acquisition Sub"), propose to enter into
an Agreement and Plan of Merger, substantially in the form of the draft dated
September 12, 2000 (the "Merger Agreement"), which provides, among other things,
for the merger (the "Merger") of Acquisition Sub with and into the Company.
Pursuant to the Merger, Servicesoft will become a wholly-owned subsidiary of
Broadbase and each outstanding share of common stock, par value $0.01 per share,
of Servicesoft ("Servicesoft Common Stock"), other than shares held in treasury
or held by Broadbase or as to which dissenters' rights have been perfected, will
be converted into the right to receive 1.4406 shares (the "Exchange Ratio") of
common stock, par value $0.01 per share, of Broadbase ("Broadbase Common
Stock"). We note that immediately prior the Closing of the Merger (as defined in
the Merger Agreement) Servicesoft shall have caused each holder of Servicesoft
Warrants and Servicesoft Preferred Stock (each as defined in the Merger
Agreement) to have exercised or converted such securities into shares of
Servicesoft Common Stock in accordance with their terms. The terms and
conditions of the Merger are more fully set forth in the Merger Agreement.

     You have asked for our opinion as to whether the Exchange Ratio pursuant to
the Merger Agreement is fair from a financial point of view to Servicesoft.

     For purposes of the opinion set forth herein, we have:

          (i) reviewed certain publicly-available financial statements and other
     information of Servicesoft and Broadbase;

          (ii) reviewed certain internal financial statements and other
     financial and operating data concerning Servicesoft and Broadbase prepared
     by the managements of Servicesoft and Broadbase, respectively;

          (iii) reviewed certain financial projections of Servicesoft and
     Broadbase prepared by the managements of Servicesoft and Broadbase,
     respectively;

          (iv) discussed the past and current operations and financial condition
     and the prospects of Servicesoft and Broadbase, including information
     relating to certain strategic, financial and operational benefits
     anticipated from the Merger, with senior executives of Servicesoft and
     Broadbase, respectively;

          (v) reviewed the reported prices and trading activity for the
     Broadbase Common Stock;

          (vi) compared the financial performance of Servicesoft and Broadbase
     and the prices and trading activity of the Broadbase Common Stock with that
     of certain other comparable publicly traded companies and their securities;

          (vii) reviewed the financial terms, to the extent publicly available,
     of certain comparable acquisition transactions;

                                       G-1
<PAGE>   311

          (viii) reviewed the Merger Agreement and certain related documents;
     and

          (ix) considered such other factors and analyses as we have deemed
     appropriate.

     We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from the Merger, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance and prospects of Broadbase and Servicesoft. We have
relied upon the assessment by the managements of Broadbase and Servicesoft of
their ability to retain key employees of Servicesoft and Broadbase. We have also
relied upon, without independent verification, the assessment by the management
of Servicesoft of Broadbase's technologies and products, the timing and risks
associated with the integration of Servicesoft with Broadbase and the validity
of, and risks associated with, Servicesoft's existing and future products and
technologies.

     In addition, we have assumed that the Merger will be consummated in
accordance with the terms set forth in the Merger Agreement, including, among
other things, that the Merger will be treated as a tax-free reorganization
and/or exchange, each pursuant to the Internal Revenue Code of 1986. We have not
made any independent valuation or appraisal of the assets or liabilities of
Servicesoft or Broadbase, nor have we been furnished with any such appraisals.
Our opinion is necessarily based on financial, economic, market and other
conditions as in effect on, and the information made available to us as of, the
date hereof.

     In arriving at our opinion, we were not authorized to solicit, and did not
solicit interest from any party with respect to the acquisition of the Company.

     We have been retained to provide a fairness opinion to the Board of
Directors of the Company in connection with this transaction and will receive a
fee for our services. As you know, and with your consent, Morgan Stanley has
acted as a financial advisor to Broadbase in connection with this transaction
and is receiving fees in connection with this transaction.

     It is understood that this letter is for the information of the Board of
Directors of the Company only and may not be used for any other purpose without
our prior written consent, except that this opinion may be included in its
entirety, if required, as part of a public filing in connection with this
transaction. In addition, this opinion does not in any manner address the prices
at which the Broadbase Common Stock will trade at any time, and Morgan Stanley
expresses no opinion or recommendation as to how the shareholders of the Company
should vote at the shareholders' meeting held in connection with the Merger.

     Based on and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a
financial point of view to the holders of shares of Servicesoft Common Stock.

                                          Very truly yours,

                                          MORGAN STANLEY & CO.

                               APPRAISAL RIGHTS:
                 DELAWARE GENERAL CORPORATIONS LAW SECTION 262

SEC. 262. APPRAISAL RIGHTS.

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d)of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 264 of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each consitutent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constitutent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constitutent corporation shall send a second notice before
     the effective date of the merger or consolidation notifying each of the
     holders of any class or series of stock of such constitutent corporation
     that are entitled to appraisal rights of the effective date of the merger
     or consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the
                                       H-2
<PAGE>   314

     facts stated therein. For purposes of determining the stockholders entitled
     to receive either notice, each constitutent corporation may fix, in
     advance, a record date that shall be not more than 10 days prior to the
     date the notice is given, provided, that if the notice is given on or after
     the effective date of the merger or consolidation, the record date shall be
     such effective date. If no record date is fixed and the notice is given
     prior to the effective date, the record date shall be the close of business
     on the day next preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has
                                       H-3
<PAGE>   315

submitted such stockholder's certificates of stock to the Register in Chancery,
if such is required, may participate fully in all proceedings until it is
finally determined that such stockholder is not entitled to appraisal rights
under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

          PART II:  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and executive officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities, including
reimbursement for expenses incurred arising under the Securities Act.

     As permitted by the Delaware General Corporation Law, our certificate of
incorporation, as amended, includes a provision that eliminates the personal
liability of its directors for monetary damages for breach of fiduciary duty as
a director, except for liability:

     - for any breach of the director's duty of loyalty to us or our
       stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - under Section 174 of the Delaware General Corporation Law (regarding
       unlawful dividends and stock purchases); or

     - for any transaction from which the director derived an improper personal
       benefit.

     As permitted by the Delaware General Corporation Law, our bylaws provide
that:

     - we are required to indemnify our directors and executive officers to the
       fullest extent permitted by the Delaware General Corporation Law, subject
       to limited exceptions;

     - we may indemnify our other employees and agents as set forth in the
       Delaware General Corporation Law;

     - we are required to advance expenses, as incurred, to our directors and
       officers in connection with a legal proceeding to the fullest extent
       permitted by the Delaware General Corporation Law, subject to limited
       exceptions; and

     - the rights conferred in the bylaws are not exclusive.

     We entered into indemnity agreements with each of our current directors and
executive officers to give such directors and executive officers additional
contractual assurances regarding the scope of the indemnification set forth in
our certificate of incorporation and to provide additional procedural
protections. The indemnification provisions in our certificate of incorporation,
bylaws and the indemnity agreements may be sufficiently broad to permit
indemnification of our directors and executive officers for liabilities arising
under the Securities Act.

     We entered into underwriting agreements with investment banks and certain
of our stockholders in connection with our initial public offering and secondary
public offering pursuant to which the underwriters agreed to indemnify us, our
directors and executive officers against certain liabilities, including
liabilities arising under the Securities Act. Likewise, pursuant to our Fourth
Amended and Restated Investors' Rights Agreement, stockholders exercising rights
pursuant to this agreement have agreed to indemnify us, our directors and our
officers who sign the registration statement against certain liabilities
including liabilities arising under the Securities Act.

     We have also obtained directors' and officers' liability insurance that
will include coverage for securities matters. At present, there is no pending
litigation or proceeding involving any of our directors, officers or employees
regarding which indemnification is sought, nor are we aware of any threatened
litigation that may result in claims for indemnification.

     See also the undertakings set out in response to Item 22.

ITEM 22.  UNDERTAKINGS.

     We hereby undertake:

     (1) To file, during any period in which offers or sales are being made, a
         post-effective amendment to this registration statement:

        (a) to include any prospectus required by Section 10(a)(3) of the
            Securities Act;

        (b) to reflect in the prospectus any facts or events arising after the
            effective date of the registration statement (or the most recent
            post-effective amendment thereof) which, individually or in the
            aggregate, represent a fundamental change in the information set
            forth in the registration statement; and

        (c) to include any material information with respect to the plan of
            distribution not previously disclosed in the registration statement
            or any material change to such information in the registration
            statement;

       provided, however, that (a) and (b) do not apply if the information
       required to be included in a post-effective amendment by (a) and (b) is
       contained in periodic reports filed with or furnished to the Commission
       by us pursuant to Section 13 or Section 15(d) of the Exchange Act that
       are incorporated by reference in the registration statement.

     (2) That, for the purpose of determining any liability under the Securities
         Act, each such post-effective amendment shall be deemed to be a new
         registration statement relating to the securities offered therein, and
         the offering of such securities at that time shall be deemed to be the
         initial bona fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
         of the securities being registered which remain unsold at the
         termination of the offering.

     (4) That, for purposes of determining any liability under the Securities
         Act, each filing of our annual report pursuant to Section 13(a) or
         Section 15(d) of the Exchange Act that is incorporated by reference in
         the registration statement shall be deemed to be a new registration
         statement relating to the securities offered in the registration
         statement, and the offering of the securities at that time shall be
         deemed to be the initial bona fide offering of those securities.

     (5) That, prior to any public reoffering of the securities registered
         hereunder through use of a prospectus which is a part of this
         registration statement, by any person or party who is deemed to be an
         underwriter within the meaning of Rule 145(c), the issuer undertakes
         that such reoffering prospectus will contain the information called for
         by the applicable registration form with respect to reofferings by
         persons who may be deemed underwriters, in addition to the information
         called for by the other items of the applicable form.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to our directors, officers and controlling persons pursuant to
the foregoing provisions, or otherwise, we have been advised that in the opinion
of the Commission such indemnification is against public policy as expressed in
the Securities Act and is, therefore unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by us of
expenses incurred or paid by one or more of our directors, officers or
controlling persons in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in connection with
the securities being registered, we will, unless in the opinion of our counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of Form S-4 within one business day of receipt of such
request, and to send the incorporated documents by first class main or

                                      II-4
<PAGE>   320

other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
