Dear E.piphany stockholder:

     You are cordially invited to attend a special meeting of the stockholders
of E.piphany, Inc. to be held at 9:00 a.m. local time, on May 31, 2000, at the
Hotel Sofitel located at 223 Twin Dolphin Drive, Redwood City, California 94065.
At the meeting, you will be asked to consider and vote upon the following
proposals:

     1. To approve the issuance of shares of E.piphany common stock to
        shareholders of Octane Software, Inc. in connection with the merger of a
        wholly-owned subsidiary of E.piphany with Octane.

     2. To transact such other business as may properly come before the special
        meeting or at any postponements or adjournments of the special meeting.

     The merger between E.piphany and Octane and related transactions are more
fully described in the proxy statement/prospectus and the annexes thereto,
including the merger agreement, accompanying this letter.

     AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE MERGER AND THE ISSUANCE OF E.PIPHANY SHARES IN THE MERGER, AND HAS
DETERMINED THESE TRANSACTIONS TO BE FAIR TO AND IN THE BEST INTERESTS OF
E.PIPHANY AND ITS STOCKHOLDERS. YOUR BOARD OF DIRECTORS RECOMMENDS A VOTE FOR
THE ISSUANCE OF E.PIPHANY SHARES IN THE MERGER.

     Any action may be taken on any of the foregoing proposals at the special
meeting on the date specified above or on any date to which the special meeting
may properly be postponed or adjourned. Only stockholders of record at the close
of business on April 14, 2000 are entitled to notice of and to vote at the
special meeting or any postponement or adjournment of the meeting.

     Your vote is very important. Whether or not you expect to attend the
meeting, please complete, date, sign and promptly return the accompanying proxy
in the enclosed postage paid envelope so that your shares may be represented at
the meeting. Returning the proxy does not deprive you of your right to attend
the meeting and vote your shares in person.

                                          On behalf of the Board of Directors,

                                          Roger S. Siboni
                                          Chairman of the Board

                                 [Octane Logo]

Dear Octane shareholder:

     You are cordially invited to attend a special meeting of the shareholders
of Octane Software, Inc. to be held at 8:00 a.m. local time, on May 31, 2000 at
the offices of Octane, 2929 Campus Drive, San Mateo, CA 94403.

     At the special meeting, you will be asked to:

     1. Approve and adopt the merger agreement, dated March 14, 2000, pursuant
        to which a wholly-owned subsidiary of E.piphany, Inc., will merge into
        Octane, causing Octane to become a wholly-owned subsidiary of E.piphany,
        and to approve such merger.

     2. To approve the conversion of all outstanding shares of Octane preferred
        stock into Octane common stock immediately prior to the merger.

     3. To transact such other business as may properly come before the special
        meeting or at any postponements or adjournments of the special meeting.

     Pursuant to the merger agreement, each outstanding share of common stock of
Octane will be converted into the right to receive approximately 0.5 of one
share of the common stock of E.piphany. In addition, each outstanding option and
warrant to purchase Octane common stock will be deemed to constitute the right
to acquire, on the same terms and conditions, a number of shares of E.piphany
common stock and at a price based on the exchange ratio described above. Please
note that the exchange ratio is subject to change based on the actual number of
shares of Octane common stock, and rights to purchase Octane common stock,
outstanding on the date of the merger, as well as other factors.

     YOUR BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND HAS DETERMINED
THAT THE MERGER AND THE CONVERSION OF THE PREFERRED STOCK IS IN THE BEST
INTERESTS OF OCTANE AND ITS SHAREHOLDERS. AFTER CAREFUL CONSIDERATION, THE BOARD
UNANIMOUSLY RECOMMENDS A VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT, THE MERGER
AND THE CONVERSION OF THE PREFERRED STOCK.

     The accompanying proxy statement/prospectus provides detailed information
concerning the proposed merger, the proposed conversion of Octane preferred
stock and additional information concerning E.piphany and Octane, which you are
urged to read carefully. The complete text of the merger agreement is attached
as Annex I to the proxy statement/prospectus.

     Only shareholders of record as of the close of business on April 14, 2000
are entitled to notice of and to vote at the special meeting or any postponement
or adjournment of the meeting. It is important that your shares of Octane stock
be represented at the special meeting, regardless of the number of shares you
hold. The required vote of Octane shareholders for approval of the merger
agreement is based on the number of outstanding shares of Octane stock and not
the number of shares which are actually voted. Accordingly, the failure to
submit a proxy card or to vote in person at the special meeting and the
abstention from voting by a shareholder will each have the same effect as a vote
against approval of the merger agreement, the merger and the conversion of
preferred stock. Therefore, please complete, sign, date and return your proxy
card as soon as possible, whether or not you plan to attend the special meeting.
You may revoke your proxy at any time prior to its exercise by filing written
notice of such revocation with the Secretary of Octane or by signing and
delivering
<PAGE>   4

to such Secretary a proxy bearing a later date. In addition, you may attend the
special meeting and vote your shares in person if you wish, even though you have
previously returned your proxy.

     OCTANE SHAREHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXIES.
THE OCTANE SHAREHOLDERS' TRANSMITTAL LETTER INCLUDED WITH THIS PROXY
STATEMENT/PROSPECTUS IS ONLY FOR USE AFTER THE MERGER HAS CLOSED. AFTER THE
MERGER IS COMPLETED, E.PIPHANY WILL SEND OCTANE SHAREHOLDERS WRITTEN NOTICE TO
SEND IN THEIR OCTANE STOCK CERTIFICATES IN EXCHANGE FOR E.PIPHANY STOCK
CERTIFICATES.

     As a holder of Octane stock you have certain dissenters' rights with
respect to the proposed merger. In order to exercise such rights, you must vote
against approval of the merger agreement. Please note that a signed proxy which
does not vote against approval of the merger agreement will be voted for such
approval. Your dissenters' rights are governed by specific legal provisions
contained in Chapter 13 of the California Corporations Code. A summary of
certain provisions of Chapter 13 of the California Corporations Code pertaining
to the rights of dissenting shareholders in connection with the merger is
included in this proxy statement/prospectus in the section entitled "Dissenters'
Rights of Octane Shareholders." The complete text of Chapter 13 of the
California Corporations Code is set forth as Annex IV to this proxy
statement/prospectus.

                                          On behalf of the Board of Directors,

                                          Aditya (Tim) Guleri
                                          Chairman of the Board of Directors and

        PROXY STATEMENT/PROSPECTUS                         PROXY STATEMENT

                    OF                                           OF
              E.PIPHANY, INC.                           OCTANE SOFTWARE, INC.
</TABLE>

     The boards of directors of E.piphany, Inc. and Octane Software, Inc. have
agreed to merge a wholly-owned subsidiary of E.piphany with and into Octane,
causing Octane to become a wholly-owned subsidiary of E.piphany. The closing of
this merger is subject to the approvals of E.piphany's stockholders and Octane's
shareholders and certain other closing conditions.

     Upon the completion of the merger, E.piphany will acquire each outstanding
share of Octane stock from Octane's shareholders in return for approximately 0.5
of a share of E.piphany common stock. Of this number, approximately 0.06 of a
share of E.piphany common stock will be placed into an escrow fund. In addition,
E.piphany will assume each outstanding option, warrant and other rights to
purchase Octane stock. The number of shares of E.piphany common stock for which
these options, warrants and other rights are exercisable, and the related
exercise price, will be adjusted based on the exchange ratio described above.
The exchange ratio is subject to change based on the actual number of shares of
Octane stock, and rights to purchase Octane stock, outstanding on the date of
the merger, as well as other factors.

     Assuming this exchange ratio and based on the capitalization of Octane as
of March 31, 2000, the approximately 11,755,138 shares of E.piphany common stock
expected to be issued in the merger, excluding the 1,038,372 shares of E.piphany
common stock subject to stock options held by Octane optionholders and assumed
by E.piphany in the merger, would represent approximately 26.6% of the shares of
E.piphany common stock outstanding and subject to options immediately following
the merger. An aggregate of approximately 1,280,000 shares to be issued in the
merger will be placed into the escrow fund.

     E.piphany common stock trades on the Nasdaq Stock Market under the symbol
"EPNY." On April 20, 2000 the closing price of E.piphany common stock was $72.25
per share.

                            ------------------------

     WE STRONGLY URGE YOU TO READ AND CONSIDER CAREFULLY THIS PROXY STATEMENT/
PROSPECTUS IN ITS ENTIRETY, INCLUDING THE MATTERS REFERRED TO UNDER "RISK
FACTORS" BEGINNING ON PAGE 16.

                            ------------------------

     NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED THE E.PIPHANY COMMON STOCK TO BE ISSUED
IN THE MERGER OR DETERMINED IF THIS PROXY STATEMENT/PROSPECTUS IS ACCURATE OR
ADEQUATE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

     The date of this proxy statement/prospectus is April   , 2000 and this
proxy statement/ prospectus and the accompanying proxy cards are first being
mailed to the stockholders of E.piphany and shareholders of Octane on or about
April   , 2000.

                             QUESTIONS AND ANSWERS
                       ABOUT THE E.PIPHANY/OCTANE MERGER

Q:  WHY ARE THE TWO COMPANIES PROPOSING TO MERGE?

A:  E.piphany and Octane believe that E.piphany's acquisition of Octane will
    enable the combined company to:

     - create a more complete software solution,

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

     - more effectively sell and market its solutions,

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

     - create a unified applications platform.

Q:  WHEN ARE THE SPECIAL STOCKHOLDERS' MEETINGS RELATING TO THE MERGER AND WHAT
    SPECIFIC PROPOSALS WILL I BE ASKED TO CONSIDER?

A1: The Octane special shareholders' meeting will take place on May 31, 2000. At
    the special meeting:

     - Octane shareholders will be asked to approve the merger agreement and the
       merger whereby a wholly-owned subsidiary of E.piphany will merge with and
       into Octane, resulting in Octane shareholders becoming stockholders of
       E.piphany, and

     - Holders of Octane preferred stock will also be asked to approve the
       automatic conversion of all Octane preferred stock into Octane common
       stock immediately prior to the completion of the merger.

The Octane board of directors unanimously recommends voting in favor of these
proposals.

    In addition, Octane shareholders will be asked to vote on any other matters
    that properly come before the meeting.

A2: The E.piphany special stockholders' meeting will take place on May 31, 2000.
    At the special meeting:

     - E.piphany stockholders will be asked to approve the issuance of shares of
       E.piphany common stock to shareholders of Octane in connection with the
       merger.

The E.piphany board of directors unanimously recommends voting in favor of this
proposal.

    In addition, E.piphany stockholders will be asked to vote on any other
    matters that properly come before the meeting.

Q:  IF I AM NOT GOING TO ATTEND THE STOCKHOLDERS' MEETING, SHOULD I RETURN MY
    PROXY CARD INSTEAD?

A:  Yes. Please fill out and sign your proxy card and return it in the enclosed
    envelope as soon as possible. Returning your proxy card ensures that your

Q:  HOW DO OCTANE'S OFFICERS AND DIRECTORS PLAN TO VOTE ON THE MERGER?

A:  Octane's board of directors has unanimously approved the merger agreement,
    the merger and the conversion of Octane preferred stock into Octane common
    stock, and recommends that Octane's shareholders approve the merger
    agreement, the merger and the conversion of Octane preferred stock into
    Octane common stock. You should also be aware that Octane's executive
    officers, directors, certain venture capital firms affiliated with the
    directors and all other affiliates of Octane have already agreed to vote in
    favor of the merger agreement, the merger and the conversion of Octane
    preferred stock into Octane common stock at the Octane special meeting.
    These shareholders possess enough votes to approve these matters even if no
    other shareholder votes in favor of these matters.

Q:  HOW DO E.PIPHANY'S OFFICERS AND DIRECTORS PLAN TO VOTE ON THE ISSUANCE OF
    SHARES OF E.PIPHANY COMMON STOCK TO OCTANE SHAREHOLDERS?

A:  E.piphany's board of directors has unanimously approved the merger
    agreement, the merger, and the issuance of shares of E.piphany common stock
    to Octane shareholders, and recommends that E.piphany's stockholders approve
    the proposed issuance of E.piphany's common stock to Octane shareholders in
    connection with the merger. You should also be aware that E.piphany's
    executive officers, directors and certain venture capital firms affiliated
    with some of these directors have already agreed to vote in favor of the
    proposed issuance of E.piphany's shares of common stock. These stockholders
    hold 31.1% of the total shares entitled to vote on these matters.

Q:  WHAT WILL HOLDERS OF OCTANE COMMON STOCK RECEIVE AS A RESULT OF THE MERGER?

A:  Based on Octane's current stock outstanding and stock subject to outstanding
    options and warrants, each Octane shareholder will be entitled to receive
    approximately 0.5 of a share of E.piphany common stock for each share of
    Octane common stock held by the shareholder at the time of the merger.

    For example, if you currently own 10,000 shares of Octane common stock, then
    after the merger you will receive approximately 5,000 shares of E.piphany
    common stock, subject to the escrow provisions described below.

Q:  WHAT IF I CURRENTLY OWN SHARES OF OCTANE PREFERRED STOCK?

A.  It is a condition of the merger that all shares of Octane preferred stock
    convert into Octane common stock prior to the merger. One of the proposals
    to be voted on at the Octane shareholders' special meeting will provide for
    automatic conversion of Octane preferred stock if the requisite vote is
    obtained. As a result of the conversion, each share of Octane preferred
    stock will convert into one share of Octane common stock.

Q:  HOW MANY SHARES OF E.PIPHANY COMMON STOCK WILL BE ISSUED IN THE MERGER?

A:  E.piphany will issue approximately 12.8 million shares of its common stock
    for all of Octane's outstanding shares of stock and shares underlying
    options and warrants to purchase Octane stock.

Q:  HOW MANY SHARES OF E.PIPHANY COMMON STOCK WILL OCTANE'S SHAREHOLDERS OWN
    AFTER THE MERGER?

A:  Based on the number of outstanding shares of Octane stock and shares
    underlying

                                        2
<PAGE>   9

options and warrants to purchase Octane stock as of March 31, 2000:

    - After the merger, shareholders of Octane will own approximately 11,755,138
      shares of E.piphany common stock.

    - In addition, Octane's outstanding options and warrants will be assumed by
      E.piphany and become options and warrants to purchase approximately
      1,038,372 shares of E.piphany common stock.

    These shares, excluding assumed options and warrants, will represent
    approximately 26.6% of E.piphany's total common stock, including options and
    warrants to purchase common stock, outstanding as of March 31, 2000.

Q:  WHAT IS THE ESCROW FUND?

A:  At the time of the merger, approximately 1.28 million shares of E.piphany
    common stock, will be placed into the escrow fund. The escrow fund will be
    held by U.S. Bank Trust, National Association.

    The escrow fund is similar to a security deposit. Octane has made various
    representations, warranties and covenants in the merger agreement. If these
    representations and warranties are inaccurate or the covenants are breached,
    E.piphany will be entitled to be compensated for its resulting losses from
    the escrow fund.

    Subject to any unresolved claims that E.piphany may have against the escrow
    fund, shares of E.piphany common stock will be released from escrow to
    Octane shareholders soon after the one year anniversary of the closing of
    the merger.

Q:  WHO IS THE OCTANE INVESTOR REPRESENTATIVE?

A:  Octane has appointed David Strohm, a director of Octane and a general
    partner of Greylock Management Corporation, Octane's largest shareholder, as
    the securityholder representative for the Octane shareholders. As such, Mr.
    Strohm will represent your interests after the merger and will be entitled
    to make certain decisions regarding the escrow fund. By approving the merger
    agreement, you will consent to the appointment of Mr. Strohm as your
    representative.

Q:  ARE OCTANE SHAREHOLDERS FREE TO IMMEDIATELY RESELL THE E.PIPHANY COMMON
    STOCK RECEIVED IN THE MERGER?

A:  Yes. However, Octane's executive officers, directors and affiliates and
    their respective affiliates will be able to resell their common stock only
    if they comply with certain securities laws that will impose additional
    restrictions on their resales.

Q:  WILL OCTANE SHAREHOLDERS RECEIVE FRACTIONAL SHARES AS A RESULT OF THE
    MERGER?

A:  No. All fractional shares of E.piphany common stock will be rounded down to
    the nearest whole share, and Octane shareholders who are entitled to receive
    less than 200 shares of E.piphany common stock will receive a cash payment
    in lieu of any fractional share equal to the fraction multiplied by $192.85.

Q:  WHAT ARE THE TAX CONSEQUENCES TO OCTANE SHAREHOLDERS OF THE MERGER?

A:  The merger is intended to be treated as a tax-free reorganization for
    federal income tax purposes. If the merger qualifies as a reorganization,
    Octane shareholders generally will not recognize gain or loss on the
    exchange of their stock in the merger. Tax matters, however, are very
    complicated and the tax consequences of the merger to you will depend on the
    facts of your particular situation. We encourage you to contact your tax
    advisors to determine the tax consequences of the merger to you. To review
    the tax consequences to Octane shareholders in greater detail, see the
    section entitled "The Merger and Related Agreements -- Certain United States
    Federal Income Tax Considerations" in this proxy statement/prospectus.

Q:  DO OCTANE SHAREHOLDERS HAVE DISSENTERS' RIGHTS IN CONNECTION WITH THE
    MERGER?

A:  Yes. Octane shareholders are entitled to dissenters' rights in connection
    with the merger. These rights are described in the section entitled
    "Dissenters' Rights of Octane Shareholders" in this proxy
    statement/prospectus.

Q:  WILL AN OCTANE SHAREHOLDER'S RIGHTS AS AN E.PIPHANY STOCKHOLDER BE DIFFERENT
    THAN AN OCTANE SHAREHOLDER'S RIGHTS AS AN OCTANE SHAREHOLDER?

A:  Yes. At the time of the merger and upon the exchange of Octane common stock
    for E.piphany common stock, each Octane shareholder will become an E.piphany
    stockholder. There are important differences between the rights of
    shareholders of Octane and stockholders of E.piphany. Please carefully
    review the description of these differences in the section entitled
    "Comparison of Capital Stock" in this proxy statement/prospectus.

Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A:  E.piphany and Octane expect to complete the merger immediately after the
    Octane and E.piphany special meetings on May 31, 2000.

Q:  WHO SHOULD I CALL WITH QUESTIONS?

A:  If you have any questions about the merger, please call James Doehrman, the
    Senior Vice President and Chief Financial Officer of Octane, at (650)
    295-6200 or Todd Friedman, the Director of Investor Relations of E.piphany

                        OF INTEREST TO OCTANE EMPLOYEES

Q:  WHAT WILL HAPPEN TO EMPLOYEE STOCK OPTIONS HELD BY OCTANE EMPLOYEES?

A:  All outstanding options to purchase shares of Octane common stock under
    Octane's 1997 Stock Option Plan, 2000 Nonstatutory Stock Option Plan and
    2000 Pennsylvania Plan, whether or not exercisable, will be assumed by
    E.piphany and be generally subject to the same terms and conditions
    governing outstanding Octane options immediately prior to the completion of
    the merger, except that the number of E.piphany common shares into which
    each outstanding Octane option will be exercisable and the exercise price
    will be appropriately adjusted to reflect the ratio of E.piphany common
    stock issuable in exchange for Octane common stock pursuant to the merger
    agreement.

Q:  MAY AN OCTANE EMPLOYEE EXERCISE OCTANE STOCK OPTIONS BETWEEN NOW AND THE
    COMPLETION OF THE MERGER?

A:  Yes. Any shares you receive by exercise of stock options prior to completion
    of the merger will be exchanged in the merger and subject to the escrow
    provisions described above.

APPROVAL OF THE MERGER AND OTHER MATTERS

     E.piphany Required Vote. Under the rules of the Nasdaq Stock Market,
approval of the issuance of shares of E.piphany common stock to Octane
shareholders in connection with the merger requires the affirmative vote of
holders of a majority of the shares of E.piphany common stock voting on this
proposal.

     All E.piphany executive officers, directors and certain of their affiliates
have agreed to vote all shares over which they exercise voting control for the
approval of The issuance of shares of E.piphany common stock to Octane
shareholders in connection with the merger. As of April 14, 2000, there were 334
stockholders of record of E.piphany common stock, and a substantially greater
number of beneficial owners, and 32,444,364 shares of E.piphany common stock
outstanding.

     Recommendation of the E.piphany Board of Directors. The E.piphany board of
directors has unanimously approved the merger agreement, the merger and the
issuance of shares of E.piphany common stock to Octane shareholders in
connection with the merger, and believes that the merger is fair to, and in the
best interests of, E.piphany and its stockholders. The E.piphany board of
directors, therefore, unanimously recommends that holders of E.piphany stock
vote FOR approval of the proposed issuance of shares of E.piphany common stock
to Octane shareholders.

     Opinion of E.piphany's Financial Advisor. E.piphany's financial advisor,
Credit Suisse First Boston, has delivered a written opinion to the E.piphany
board of directors as to the fairness, from a financial point of view, to
E.piphany of the consideration provided for in the merger, which for purposes of

shares of E.piphany common stock and options, warrants and other rights to
purchase E.piphany common stock to be issued to Octane shareholders in the
merger. The full text of Credit Suisse First Boston's written opinion is
attached to this document as Annex V. We encourage you to read this opinion
carefully in its entirety for a description of the procedures followed,
assumptions made, matters considered and limitations on the review undertaken.

DIRECTORS AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY E.PIPHANY STOCKHOLDER
OR ANY OCTANE SHAREHOLDER AS TO ANY MATTER RELATING TO THE MERGER.

                                        6
<PAGE>   13

     Octane Required Vote. Under applicable California law and the charter
documents of Octane, approval of the merger requires the affirmative vote of
holders of:

     - a majority of the outstanding shares of Octane common stock,

     - a majority of the outstanding shares of Octane preferred stock, and

     - a majority of all outstanding shares of Octane common stock and preferred
       stock, voting together on an as-converted to common stock basis.

     In addition to the merger and the merger agreement, the holders of Octane
preferred stock are being asked to approve the automatic conversion of the
Octane preferred stock into Octane common stock effective immediately prior to
the merger. Approval of the preferred stock conversion requires the affirmative
vote of the holders of 66 2/3% of the outstanding shares of Octane preferred
stock voting together.

     All Octane executive officers, directors, venture capital firms affiliated
with the directors and all other affiliates have agreed to vote all shares over
which they exercise voting control for the approval of the merger agreement, the
merger and conversion of the preferred stock.

     As of April 14, 2000, there were:

     - 214 shareholders of record of Octane common stock and 9,729,189 shares of
       Octane common stock outstanding,

     - 60 shareholders of record of Octane preferred stock and 12,951,320 shares
       of Octane preferred stock outstanding,

     - 271 shareholders of record of Octane common stock and preferred stock and
       22,680,509 shares of Octane common stock and preferred stock outstanding
       on an as-converted to common stock basis.

     Recommendation of the Octane Board of Directors. The Octane board of
directors has unanimously approved the merger agreement, the merger and the
conversion of preferred stock and believes that the merger agreement, the merger
and the conversion of preferred stock is fair to, and in the best interests of,
Octane and its shareholders. The Octane board of directors, therefore,
unanimously recommends that holders of Octane stock vote FOR approval of the
merger agreement, the merger and the conversion of preferred stock.

     Interests of Octane Officers and Directors in the Merger. In considering
the Octane board of directors' recommendation that you approve the merger
agreement, the merger and the conversion of preferred stock, you should note
that Octane's officers and directors have interests in the merger that are
different from, or in addition to, your interests. Specifically, as a result of
or in connection with the merger:

     - certain Octane officers and directors will become officers of E.piphany,
       and

     - the vesting of some of the stock and stock options held by Octane's
       officers and directors will accelerate as a result of the merger.

     As a result of, or in connection with, the merger Octane's directors and
officers could be more likely to vote to approve the merger agreement, the
merger and the conversion of preferred stock than Octane shareholders generally.

THE MERGER AND MERGER AGREEMENT

     Effective Time of the Merger. The merger will become effective upon the
effectiveness of the filing of articles of merger with the Secretary of State of
California. Assuming all conditions to the merger are met or waived prior
thereto, it is anticipated that the closing of the merger will be on or about
May 31, 2000.

     Effect of the Merger. At the closing of the merger, Orchid Acquisition
Corporation, a wholly-owned subsidiary of E.piphany, will be merged with and
into Octane, the separate corporate existence of Orchid Acquisition Corporation
will cease and Octane will continue as the surviving corporation and as a
wholly-owned subsidiary of E.piphany.

     Subject to the approval of the holders of Octane preferred stock, all
shares of Octane preferred stock will be converted into Octane common stock
immediately prior to the merger.
                                        7
<PAGE>   14

     As of the closing of the merger, by virtue of the merger and without any
action on the part of Orchid Acquisition Corporation, Octane or the holder of
any shares of Octane capital stock, the following will occur in accordance with
the terms and conditions of the merger agreement:

     - All outstanding shares of Octane common stock will be converted into the
       right to receive approximately 0.5 of a share of E.piphany common stock,
       and

     - All outstanding options, warrants and other rights to purchase Octane
       capital stock will be assumed by E.piphany and will become options,
       rights and warrants to purchase E.piphany common stock. The exercise
       price and number of shares of E.piphany common stock for which they are
       convertible will be adjusted to reflect the exchange ratio of
       approximately 0.5 of a share of E.piphany common stock for each share of
       Octane common stock.

     Escrow Fund. In connection with the merger, approximately 1.28 million
shares of E.piphany common stock issuable in connection with the merger will be
placed in escrow with U.S. Bank Trust, National Association. Each Octane
shareholder will be deemed to have contributed into the escrow fund in
proportion to the aggregate number of shares of E.piphany common stock that such
shareholder would otherwise have been entitled under the merger agreement. The
escrow fund will be available to compensate E.piphany for any losses as a result
of any inaccuracy or breach of a representation or warranty of Octane contained
in the merger agreement or any failure to comply with any covenant contained in
the merger agreement. E.piphany may not receive any shares from the escrow fund
for a breach of a representation, warranty or covenant unless and until
E.piphany suffers cumulative losses in excess of $1.75 million ($500,000 in the
event of representations, warranties or covenants related to intellectual
property issues). Subject to any unresolved claims that E.piphany may have
against the escrow fund, shares of E.piphany common stock will be released from
escrow to Octane shareholders soon after the one year anniversary of the closing
of the merger.

     Conduct Prior to the Merger. Octane has generally agreed to operate its
business in the ordinary course and consistent with past practice prior to the
merger. Octane has also agreed not to initiate or engage in discussions
regarding a business combination with any party other than E.piphany unless and
until the merger agreement is terminated.

     Conditions to the Merger. Consummation of the merger is subject to the
satisfaction of various conditions, including:

     - approval of the issuance of shares of E.piphany common stock to Octane
       shareholders in connection with the merger by the requisite vote of the

       of representations, warranties or covenants contained in the merger
       agreement,

     - by either E.piphany or Octane if the other suffers a material adverse
       change prior to the merger, or

OTHER CONSIDERATIONS

     Market Price Data. E.piphany common stock has been traded on the Nasdaq
Stock Market's National Market under the symbol "EPNY" since E.piphany's initial
public offering in September 1999. On March 14, 2000, the last trading day
before the announcement by E.piphany and Octane that they had signed the merger
agreement, the closing price of E.piphany common stock as reported on the Nasdaq
Stock Market's National Market was $248.94 per share. On April 20, 2000, the
closing price of E.piphany common stock as reported on the Nasdaq Stock Market's
National Market was $72.25. There can be no assurance as to the actual price of
E.piphany common stock prior to, at, or at any time following the closing of the
merger.

     No established trading market exists for Octane stock.

     Certain Federal Income Tax Considerations. The merger is intended to
qualify as a reorganization under Section 368(a) of the Internal Revenue Code.
If the merger so qualifies, no gain or loss will generally be recognized by the
holders of shares of Octane stock on the exchange of their shares of Octane
stock for shares of E.piphany common stock. All Octane shareholders should read
carefully the discussion in the "The Merger and Related Transactions -- Certain
United States Federal Income Tax Considerations" section of this proxy
statement/prospectus. FURTHER, ALL OCTANE SHAREHOLDERS ARE URGED TO CONSULT
THEIR OWN TAX ADVISORS AS TO THE TAX CONSEQUENCES OF THE MERGER TO THEM.

     Accounting Treatment. E.piphany intends to account for the merger as a
purchase for financial reporting purposes in accordance with generally accepted
accounting principles. See the sections entitled "The Merger and Related
Transactions -- Accounting Treatment" and "E.piphany Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Octane Acquisition"
in this proxy statement/prospectus.

     Adjustments to Exchange Ratio. The number of shares of E.piphany common
stock issuable in the merger, and the resulting exchange ratio, are subject to
adjustment in the event that E.piphany effects a stock split, stock dividend,
cash dividend, distribution, reorganization or recapitalization prior to the
merger.

     Regulatory Approvals. As required under federal antitrust law, E.piphany
and Octane have notified the Department of Justice and Federal Trade Commission
of the proposed merger. If neither of these agencies request additional
information concerning the merger or object to the merger within thirty days of
the notice, E.piphany and Octane may proceed with the merger.

     Dissenters' Rights. Holders of Octane stock who do not vote in favor of the
merger may, under certain circumstances and by following procedures prescribed
by California law, exercise dissenters' rights and receive cash for their shares
of Octane stock. A dissenting shareholder of Octane must follow the appropriate
procedures under California law or he or she will lose such rights. See the
section entitled "Dissenters' Rights of Octane Shareholders" in this proxy
statement/prospectus.

                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

     The unaudited summary pro forma combined condensed financial information of
E.piphany, RightPoint and Octane is derived from, and should be read in
conjunction with, the unaudited pro forma combined condensed financial

operations data, the operations of RightPoint and Octane have been included as
if each merger had occurred at the beginning of the earliest period presented.
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 beginning of the earliest period
presented, nor is it necessarily indicative of future operating results or
financial position of the combined companies.

                           COMPARATIVE PER SHARE DATA

     The following table sets forth certain historical per share data of
E.piphany and Octane and combined per share data on an unaudited pro forma basis
after giving effect to the merger (and the acquisition of RightPoint by
E.piphany) and assuming that 0.5179 of a share of E.piphany common stock is
issued in exchange for each outstanding share of Octane common stock and stock
underlying options and warrants. This data should be read in conjunction with
the selected historical financial information, the pro forma unaudited combined
condensed financial information and the separate historical financial statements
of E.piphany and notes thereto and historical consolidated financial statements
of Octane and notes thereto, included elsewhere in this proxy
statement/prospectus. All historical and pro forma share amounts are computed as
if the preferred shares of E.piphany and Octane were converted to common stock
from their date of issuance. The pro forma unaudited combined condensed
financial information is not necessarily indicative of the operating results
that would have been achieved had the transaction been in effect as of the
beginning of the periods presented and should not be construed as representative
of future operating results.

     The equivalent Octane pro forma share amounts are calculated by multiplying
the combined pro forma per share amounts by the estimated exchange ratio of
0.5179 of a share of E.piphany common stock for each share of Octane common
stock, assuming the conversion of all Octane preferred stock into Octane common
stock.

     Pro forma combined net loss per share reflects E.piphany's and Octane's
respective net loss for the year ended December 31, 1999 and the three months
ended March 31, 2000 and is based upon E.piphany's weighted average common
shares outstanding for the periods presented, and approximately 11,755,138
shares of E.piphany's common stock assumed to be issued in the merger, which
excludes options and warrants to purchase approximately 1,038,372 shares of
common stock which will be assumed in the merger.

     There is no established trading market for Octane capital stock.

     As of April 14, 2000, E.piphany estimates that there were approximately 334
holders of record of E.piphany common stock and a substantially greater number
of beneficial owners. As of April 14, 2000, there were approximately 271 holders
of record of Octane capital stock.

     To date, E.piphany has not declared or paid dividends on its common stock.
The board of directors of E.piphany presently intends to retain all earnings for
use in E.piphany's business and therefore does not anticipate declaring or
paying any cash dividends in the foreseeable future. In addition, E.piphany's
credit facilities restrict the payment of dividends. To date, Octane has not
declared or paid dividends on its common stock. In addition, Octane's credit
facilities restrict the payment of dividends. The board of directors of Octane
presently intends to retain all earnings for use in Octane's business and
therefore does not anticipate declaring or paying any cash dividends in the
foreseeable future.

     The table below sets forth the high and low sales prices per share of
E.piphany common stock on the Nasdaq Stock Market's National Market on March 14,
2000, the last completed trading day prior to the signing and announcement of
the merger agreement, and on April 20, 2000. Also set forth is the implied
equivalent value of one share of Octane common stock on each such date assuming
an exchange ratio of approximately 0.5 of a share of E.piphany common stock for
each share of Octane common stock and the conversion of all Octane preferred
stock into Octane common stock.

     As the table above indicates, fluctuations in the market price of E.piphany
common stock affect the value of the Octane shares for which they are exchanged.
The table illustrates that between March 14, 2000, and April 20, 2000, the value
of a share of Octane common stock, had it been exchanged for E.piphany common
stock at the assumed exchange ratio, would have fluctuated between $145.00 and
$31.50.

     The foregoing table shows only historical comparisons. These comparisons
may not provide meaningful information to you in determining whether to approve
the merger and the merger agreement. Because the number of shares of E.piphany
to be issued to the holders of Octane common stock is fixed, changes in the
market price of E.piphany common stock will affect the dollar value of E.piphany
common stock to be received by shareholders of Octane in the merger. Octane
shareholders are urged to obtain current market quotations for E.piphany common
stock, and to review carefully the other information contained in this proxy
statement/prospectus, prior to considering whether to approve the merger
agreement, the merger and the conversion of preferred stock.

                                  RISK FACTORS

     You should carefully consider the risks described below before making your
decision to consent to the issuance of E.piphany shares to Octane shareholders,
the merger agreement and the merger. The risks and uncertainties described below
are not the only ones facing E.piphany and Octane. Additional risks and
uncertainties not presently known to us or that we do not currently believe are
important to an investor may also harm our business operations.

     If any of the events, contingencies, circumstances or conditions described
in the following risks actually occur, our business, financial condition or our
results of operations could be seriously harmed. If that happens, the trading
price of E.piphany common stock could decline, and you may lose part or all of
the value of any E.piphany shares held by you.

RISKS RELATED TO THE MERGER.

E.PIPHANY AND OCTANE MAY NOT REALIZE ANY BENEFITS FROM THE MERGER.

     Achieving the benefits of the merger will depend in part on the integration
of technology, operations and personnel. The integration of E.piphany and Octane
will be a complex, time consuming and expensive process and may disrupt
E.piphany's business if not completed in a timely and efficient manner. Among
the challenges involved in this integration are demonstrating to customers and
suppliers that the merger will not result in adverse changes in client service
standards or business focus, persuading our employees that E.piphany's and
Octane's business cultures are compatible and retaining key personnel. Neither
E.piphany nor Octane has experience in integrating operations on the scale
represented by the merger, and it is not certain that E.piphany and Octane can
be successfully integrated in a timely manner or at all or that any of the
anticipated benefits of the merger will be realized. Failure to do so could
seriously harm the business, financial condition and operating results of the
combined company.

BECAUSE THE TOTAL MERGER CONSIDERATION IS FIXED, DECREASES IN E.PIPHANY'S
TRADING PRICE WILL REDUCE THE VALUE OF WHAT OCTANE SHAREHOLDERS RECEIVE IN THE
MERGER.

     All of the outstanding shares of Octane capital stock and the options to
purchase shares of Octane's capital stock shall be exchanged for a fixed number
of shares of E.piphany common stock and options to purchase E.piphany common
stock totaling approximately 12.8 million shares. There will be no adjustment
for changes in the market price of E.piphany common stock, and Octane is not
permitted to withdraw from the merger or resolicit the vote of its shareholders
solely because of changes in the market price of E.piphany common stock.
Accordingly, the actual dollar value of E.piphany common stock that Octane
shareholders will receive upon completion of the merger will depend on the
market value of E.piphany common stock at the time of completion of the merger.

     For a description of how E.piphany's market price has in the past
fluctuated greatly and may continue to fluctuate in the future, refer to
"-- Risks Related to E.piphany and to the Combined Company Following the
Merger -- Variations in Quarterly Operating Results Due to Such Factors as
Changes in Demand For Our Products and Changes in Our Mix of Revenues May Cause
Our Stock Price to Decline." The market price of E.piphany common stock on a
recent date is set forth under "Market Price Information."

IF E.PIPHANY AND OCTANE DO NOT INTEGRATE THEIR TECHNOLOGY QUICKLY AND
EFFECTIVELY, MANY OF THE POTENTIAL BENEFITS OF THE MERGER MAY NOT BE REALIZED.

     E.piphany intends to integrate Octane's technology into its own software
solutions as well as offer Octane's solutions separately. E.piphany and Octane
cannot assure you that they will be able to integrate their technology quickly
and effectively. In order to obtain the benefits of the merger,

                                       16
<PAGE>   23

E.piphany must make Octane's technology, products and services operate together
with E.piphany's technology, products and services. E.piphany may be required to
spend additional time or money on integration which would otherwise be spent on
developing its own business and services. If E.piphany does not integrate the
technology effectively or if management spends too much time on integration
issues, it could harm the combined companies' business, financial condition and
results of operations.

THE MERGER MAY RESULT IN A LOSS OF OCTANE OR E.PIPHANY EMPLOYEES.

     Despite E.piphany's efforts to hire and retain quality employees, E.piphany
might lose some of Octane's or its own employees following the merger.
Competition for qualified management, engineering and technical employees in the
software industry is intense. E.piphany and Octane have different corporate
cultures, and Octane employees may not want to work for a larger,
publicly-traded company instead of a smaller, start-up company. Some key
employees of Octane hold options which will partially vest as a result of the
merger, and this may affect E.piphany's ability to retain these employees. In
addition, competitors may recruit employees prior to the merger and during
integration, as is common in high technology mergers. As a result, employees of
Octane or the combined company could leave with little or no prior notice.
E.piphany and Octane cannot assure you that the combined company will be able to
attract, retain and integrate employees following the merger.

     As a condition to the merger, Aditya (Tim) Guleri, William Walsh, Kira
Makagon, James Doehrman, Robert Loughan, Robert Gryphon, Todd Rowe, Andrew
Sherman, Gary Schaumburg and Manu Kumar have entered into employment and
non-competition agreements which will restrict their ability to compete with
E.piphany if they leave E.piphany. E.piphany and Octane cannot assure you of the
enforceability of these non-competition agreements or that these employees will
continue to work at E.piphany under their employment agreements after the
merger.

THE MERGER MAY RESULT IN A LOSS OF CUSTOMERS.

     As a result of the merger some customers or potential customers may not
continue to do business with Octane. In such case, we may lose significant
revenue Octane might have otherwise received had the merger not occurred.

MERGER RELATED ACCOUNTING CHARGES WILL DELAY AND REDUCE E.PIPHANY'S
PROFITABILITY.

     The Octane acquisition is being accounted for by E.piphany under the
"purchase" method of accounting. Under the purchase method, the purchase price
of Octane will be allocated to the assets and liabilities acquired from Octane.
As a result, E.piphany will incur accounting charges from the merger which will
delay and reduce E.piphany's profitability. These charges are currently
estimated to include:

     - amortization of intangible assets estimated to be approximately $2.7
       billion amortized over three years,

     - in-process research and development of approximately $25 million, to be
       expensed in the quarter ended June 30, 2000, and

     - other costs not currently known.

IF THE CONDITIONS TO THE MERGER ARE NOT MET, THE MERGER WILL NOT OCCUR.

     Several conditions must be satisfied or waived to complete the merger.
These conditions are described under "Terms of the Merger -- Conditions to the
Merger" and in detail in the merger agreement. E.piphany and Octane cannot
assure you that each of the conditions will be satisfied. If the conditions are
not satisfied or waived, the merger will not occur or will be delayed, and
E.piphany and Octane each may lose some or all of the intended benefits of the
merger. For example, if either

                                       17
<PAGE>   24

party's representations and warranties are not materially true and correct at
the closing or either party suffers a material adverse change in its condition
prior to closing, the other party may not be required to close. If the merger is
not completed, Octane will require substantial additional capital resources to
continue its business, which resources may not be available on favorable terms,
or at all.

OCTANE OFFICERS AND DIRECTORS HAVE CONFLICTS OF INTEREST THAT MAY INFLUENCE THEM
TO SUPPORT OR APPROVE THE MERGER.

     Some of the directors and officers of Octane have entered into agreements
with E.piphany that provide them with interests in the merger that are different
from, or are in addition to, your interests. In particular, Aditya (Tim) Guleri,
William Walsh, Kira Makagon, James Doehrman, Robert Loughan, Robert Gryphon,
Todd Rowe, Andrew Sherman, Gary Schaumburg and Manu Kumar have entered into
employment agreements with E.piphany, and some of these Octane officers and
directors may become officers of E.piphany following the merger. In addition,
the vesting of a portion of the stock options held by directors and officers of
Octane will accelerate as a result of the merger. As a result, these directors
and officers could be more likely to vote to approve the merger agreement than
if they did not hold these interests. Octane shareholders should consider
whether these interests may have influenced these directors and officers to
support or recommend the merger.

RISKS RELATED TO AN INVESTMENT IN E.PIPHANY AND TO THE COMBINED COMPANY
FOLLOWING THE MERGER.

E.PIPHANY AND OCTANE HAVE A HISTORY OF LOSSES, EXPECT LOSSES IN THE FUTURE AND
THE COMBINED COMPANY MAY NOT EVER BECOME PROFITABLE.

     E.piphany incurred net losses of $67.0 million for the quarter ended March
31, 2000, $22.4 million in the year ended December 31, 1999, $10.3 million in
the year ended December 31, 1998 and $3.1 million in the year ended December 31,
1997. E.piphany had an accumulated deficit of $102.8 million as of March 31,
2000, and $35.9 million as of December 31, 1999. Octane incurred net losses of
$14.0 million for the quarter ended March 31, 2000, $14.4 million for the year
ended December 31, 1999 and $1.4 million for the year ended December 31, 1998.
Octane had an accumulated deficit of $33.9 million at March 31, 2000, and $18.3
million at December 31, 1999. E.piphany expects to continue to incur losses
before amortization charges for the foreseeable future. In addition, in
connection with the acquisitions of Octane and RightPoint, E.piphany will incur
significant accounting charges for the amortization of intangible assets over
the three years following these mergers. These losses will be substantial, and
E.piphany may not ever become profitable. In addition, E.piphany expects to
significantly increase its expenses in the near term, especially research and
development and sales and marketing expenses. Therefore, E.piphany's operating
results will be harmed if E.piphany's revenue does not keep pace with its
expected increase in expenses or is not sufficient for E.piphany to achieve
profitability. If E.piphany does achieve profitability in any period, it cannot
be certain that it will sustain or increase profitability on a quarterly or
annual basis.

E.PIPHANY'S AND OCTANE'S LIMITED OPERATING HISTORY MAKES FINANCIAL FORECASTING
AND EVALUATION OF THE COMBINED COMPANY'S BUSINESS DIFFICULT.

     E.piphany's and Octane's limited operating history makes it difficult to
forecast the combined company's future operating results. E.piphany was founded
in November 1996 and began developing products in 1997. Octane was founded in
1997 and began developing products in 1998. E.piphany's revenue and income
potential is unproven. E.piphany received its first revenues from licensing its
software and performing related services in early 1998, and began shipping the
E.piphany E.4 System software in June 1999. Octane began offering its products
in the third quarter of 1999. Since neither company has a long history upon
which to base forecasts of future operating results, any predictions about our
future revenues and expenses may not be as accurate as they would be if
E.piphany and Octane had a longer business history.

                                       18
<PAGE>   25

VARIATIONS IN QUARTERLY OPERATING RESULTS DUE TO SUCH FACTORS AS CHANGES IN
DEMAND FOR OUR PRODUCTS AND CHANGES IN OUR MIX OF REVENUES MAY CAUSE OUR STOCK
PRICE TO DECLINE.

     E.piphany expects its and Octane's quarterly operating results to
fluctuate. We therefore believe that quarter-to-quarter comparisons of our
operating results may not be a good indication of our future performance, and
you should not rely on them to predict our future performance or the future
performance of E.piphany's stock price. Our short-term expense levels are
relatively fixed and are based on our expectations of future revenues. As a
result, a reduction in revenues in a quarter may harm our operating results for
that quarter. Our quarterly revenues, expenses and operating results could vary
significantly from quarter-to-quarter. If our operating results in future
quarters fall below the expectations of market analysts and investors, the
trading price of E.piphany's common stock will fall. Factors that may cause our
operating results to fluctuate on a quarterly basis are:

     - varying size, timing and contractual terms of orders for our products,

     - our ability to timely complete its service obligations related to product
       sales,

     - changes in the mix of revenue attributable to higher-margin product
       license revenue as opposed to substantially lower-margin service revenue,

     - customers' decisions to defer orders or implementations, particularly
       large orders or implementations, from one quarter to the next,

     - changes in demand for our software or for enterprise software and real
       time marketing solutions generally,

     - announcements or introductions of new products by our competitors,

     - software defects and other product quality problems,

     - any increase in our need to supplement our professional services
       organization by subcontracting to more expensive consulting organizations
       to help provide implementation, support and training services when our
       own capacity is constrained, and

     - our ability to hire, train and retain sufficient engineering, consulting,
       training and sales staff.

THE LOSS OF KEY PERSONNEL OR ANY INABILITY TO ATTRACT AND RETAIN ADDITIONAL
PERSONNEL COULD AFFECT E.PIPHANY'S ABILITY TO SUCCESSFULLY GROW ITS BUSINESS.

     E.piphany's future success will depend in large part on its ability to hire
and retain a sufficient number of qualified personnel, particularly in sales,
marketing, research and development, service and support. If E.piphany is unable
to do so, this inability could affect its ability to grow its business.
Competition for qualified personnel in high technology is intense, particularly
in the Silicon Valley region of Northern California where E.piphany's principal
offices are located. E.piphany's future success also depends upon the continued
service of its executive officers and other key sales, engineering and technical
staff. The loss of the services of E.piphany's executive officers and other key
personnel would harm E.piphany's operations. None of E.piphany's officers or key
personnel is bound by an employment agreement, other than Gayle Crowell, and the
Octane employees who entered into agreements in connection with the merger, and
E.piphany does not maintain key person insurance on any of its employees.
E.piphany would also be harmed if one or more of E.piphany's officers or key
employees decided to join a competitor or otherwise compete with E.piphany.

     The market price of E.piphany's common stock has increased substantially
since its initial public offering in September 1999. Consequently, potential
employees may perceive E.piphany's equity incentives such as stock options as
less attractive. In that case, E.piphany's ability to attract employees will be
adversely affected. Furthermore, a substantial portion of the equity incentives
previously granted to Octane employees will accelerate and become substantially
vested upon the

                                       19
<PAGE>   26

closing of the mergers. New options granted to Octane employees at the current
market price of E.piphany's common stock may not be sufficient to retain Octane
employees. Finally, should E.piphany's stock price decline substantially, the
retention value of stock options granted since E.piphany's initial public
offering will decline and E.piphany's employees may choose not to remain
employed by E.piphany.

IF CUSTOMERS DO NOT CONTRACT DIRECTLY WITH CONSULTING ORGANIZATIONS TO IMPLEMENT
AND SUPPORT E.PIPHANY'S AND OCTANE'S PRODUCTS, OUR REVENUES, PROFITABILITY AND
MARGINS MAY BE HARMED.

     E.piphany's and Octane's principal focus is providing software solutions
rather than services. As a result, we encourage our customers to purchase
consulting, implementation, maintenance and training services directly from
consulting organizations instead of purchasing these services from us. While we
do not receive any fees directly from these consulting organizations when they
contract directly with our customers, we believe that these consulting
organizations increase market awareness and acceptance of our software solutions
and allow us to focus on software development and licensing. If consulting
organizations are unwilling or unable to provide a sufficient level and quality
of services directly to our customers or if customers are unwilling to contract
directly with these consulting organizations, we may not realize these benefits
and our revenues and profitability may be harmed.

     Further, to the extent that consulting organizations do not provide
consulting, implementation, maintenance and training services directly to our
customers, we need to provide these services to our customers. We provide these
services to our customers either directly through our internal professional
services organization or indirectly through subcontractors we hire to perform
the services on our behalf. Because our margins on service revenues are less
than our margins on license revenues, our overall margins decline when we
provide services to customers. This is particularly true if we hire
subcontractors to perform these services because it costs us more to hire
subcontractors to perform these services than to provide the services ourselves.

IF THE COMBINED COMPANY'S INTERNAL PROFESSIONAL SERVICES ORGANIZATION DOES NOT
PROVIDE IMPLEMENTATION SERVICES EFFECTIVELY AND ACCORDING TO SCHEDULE, OUR
REVENUES AND PROFITABILITY WOULD BE HARMED.

     Customers that license E.piphany's products typically require consulting,
implementation, maintenance and training services and obtain them from
E.piphany's internal professional services organization, which employed a staff
of 93 as of March 31, 2000, or from outside consulting organizations. Octane
employed a staff of 60 in its internal professional services organization as of
March 31, 2000. When we provide these services, we generally recognize revenue
from the licensing of our software products as the implementation services are
performed. If our internal professional services organization does not
effectively implement and support our products or if we are unable to expand our
internal professional services organization as needed to meet our customers'
needs, our ability to sell software, and accordingly our revenues, will be
harmed.

     In addition, when we sell licenses together with professional services for
implementation, we generally recognize the revenue from both the license and the
services as we perform the implementation services. Therefore, delays in
providing implementation services will delay our recognition of revenue. If we
are unable to expand our internal professional services organization to keep
pace with sales, we will be required to increase our use of subcontractors to
help meet our implementation and service obligations, which will result in lower
gross margins. In addition, we may be unable to negotiate agreements with
subcontractors to provide a sufficient level and quality of services. If we fail
to retain sufficient subcontractors, our ability to sell software for which
these services are required will be harmed and our revenues will suffer.

                                       20
<PAGE>   27

OUR SERVICES REVENUES HAVE A SUBSTANTIALLY LOWER MARGIN THAN OUR PRODUCT
REVENUES, AND AN INCREASE IN SERVICE REVENUES RELATIVE TO LICENSE REVENUES COULD
HARM OUR GROSS MARGINS.

     E.piphany's services revenues, which includes fees for consulting,
implementation, maintenance and training, were 43% of its revenues for the
quarter ended March 31, 2000, 47% of its revenues for the year ended December
31, 1999 and 34% of E.piphany's revenues for the year ended December 31, 1998.
Octane's services revenues were 46% of its revenues for the quarter ended March
31, 2000, 81% of its revenues for the year ended December 31, 1999 and 100% of
revenues for the year ended December 31, 1998. Both companies' services revenues
have substantially lower gross margins than license revenues. E.piphany's cost
of services revenues for the quarter ended March 31, 2000 and the year ended
December 31, 1999 was 98% and 102%, respectively, of its services revenues.
Octane's cost of services revenues for the quarter ended March 31, 2000 and the
year ended December 31, 1999 was 94% and 59%, respectively, of its services
revenues. An increase in the percentage of total revenues represented by
services revenues could adversely affect our overall gross margins.

     Services revenues as a percentage of total revenues and cost of services
revenues as a percentage of total revenues have varied significantly from
quarter to quarter due to our relatively early stage of development. The
relative amount of services revenues as compared to license revenues has varied
based on the volume of software solution orders compared to the volume of
additional user orders. In addition, the amount and profitability of services
can depend in large part on:

     - the software solution which has been licensed,

     - the complexity of the customers' information technology environment,

     - the resources directed by customers to their implementation projects,

     - the number of users licensed, and

     - the extent to which outside consulting organizations provide services
       directly to customers.

NEW PRODUCT INTRODUCTIONS AND PRICING STRATEGIES BY E.PIPHANY'S COMPETITORS
COULD ADVERSELY AFFECT E.PIPHANY'S ABILITY TO SELL ITS PRODUCTS AND COULD RESULT
IN PRESSURE TO PRICE E.PIPHANY'S PRODUCTS IN A MANNER THAT REDUCES ITS MARGINS.

     Competitive pressures could prevent E.piphany from growing, reduce
E.piphany's market share or require E.piphany to reduce prices on its products
and services, any of which could harm E.piphany's business.

     E.piphany competes principally with vendors of:

     - data management and data analysis software tools, such as Brio
       Technology, Broadbase, Business Objects, Informatica, Microstrategy and
       Sagent Technology,

     - enterprise application software, such as Oracle, PeopleSoft, SAP and
       Siebel Systems,

     - marketing campaign management software tools, such as Exchange
       Applications, Prime Response, and Recognition Systems,

     - software that recommends products to customers in real-time based on
       simple analytics rules such as Net Perceptions, and

     - electronic customer relations management software, such as Kana
       Communications (Silknet Software), eGain, Primus Knowledge Solutions,
       Nortel (Clarify), PeopleSoft (Vantive), and Siebel Systems (Scopus).

                                       21
<PAGE>   28

     Many of these companies have significantly greater financial, technical,
marketing, service and other resources. Many of these companies also have a
larger installed base of users, have been in business longer or have greater
name recognition than we do. For example, in fiscal 1999, Oracle's annual
revenue exceeded $8.0 billion, and the annual revenue of Siebel Systems in
fiscal 1999 exceeded $790 million. Some large companies may attempt to build
capabilities into their products that are similar to the capabilities of our
products. Some of our competitors' products may be more effective than our
products at performing particular functions or be more customized for particular
needs. Even if these functions are more limited than those provided by our
products, our competitors' software products could discourage potential
customers from purchasing our products. For example, our competitors' software
products may incorporate other capabilities, such as recording accounting
transactions, customer orders or inventory management data. A software product
that performs these functions, as well as some of the functions of our software
solutions, may be appealing to some customers because it would reduce the number
of different types of software necessary to effectively run their business.
Further, our competitors may be able to respond more quickly than we can to
changes in customer requirements.

     In addition, our products must integrate with software solutions provided
by a number of our existing or potential competitors. These competitors could
alter their products so that our products no longer integrate well with them, or
they could deny or delay access by us to advance software releases that allow us
to timely adapt our products to integrate with their products.

     E.piphany's competitors have made and may also continue to make strategic
acquisitions or establish cooperative relationships among themselves or with
other software vendors. This may increase the ability of their products to
address the need for software solutions such as ours which provide both the
ability to collect data from multiple sources and analyze that data to profile
customer characteristics and preferences. E.piphany's competitors may also
establish or strengthen cooperative relationships with our current or future
distributors or other parties with whom we have relationships, thereby limiting
our ability to sell through these channels, reducing promotion of E.piphany's
products and limiting the number of consultants available to implement
E.piphany's software.

E.PIPHANY'S REVENUES MIGHT BE HARMED BY RESISTANCE TO ADOPTION OF E.PIPHANY'S
SOFTWARE BY INFORMATION TECHNOLOGY DEPARTMENTS.

     Some businesses may have already made a substantial investment in other
third party or internally developed software designed to integrate data from
disparate sources and analyze this data or manage marketing campaigns. These
companies may be reluctant to abandon these investments in favor of our
software. In addition, information technology departments of potential customers
may resist purchasing our software solutions for a variety of other reasons,
particularly the potential displacement of their historical role in creating and
running software and concerns that packaged software products are not
sufficiently customizable for their enterprises. If the market for our products
does not grow for any of these reasons, our revenues will be harmed.

                                       22
<PAGE>   29

IF THE MARKET IN WHICH WE SELL OUR PRODUCTS AND SERVICES DOES NOT GROW AS WE
ANTICIPATE, OUR REVENUES WILL BE REDUCED.

     If the market for software that enables companies to establish, manage,
maintain and continually improve customer relationships by collecting and
analyzing data to design and manage marketing campaigns and customize products
and services and providing timely, consistent, multichannel customer interaction
does not grow as quickly or become as large as we anticipate, our revenues will
be reduced. Our market is still emerging, and our success depends on its growth.
Our potential customers may:

     - not understand or see the benefits of using these products,

     - not achieve favorable results using these products,

     - experience technical difficulty in implementing or using these products,
       or

     - use alternative methods to solve the same business problems.

     In addition, because our products can be used in connection with Internet
commerce and we are currently developing additional Internet commerce solutions,
if the Internet commerce market does not grow as quickly as we anticipate, we
may experience sales which are lower than our expectations.

IF THE COMBINED COMPANY FAILS TO DEVELOP NEW PRODUCTS OR IMPROVE ITS EXISTING
PRODUCTS TO MEET OR ADAPT TO THE CHANGING NEEDS AND STANDARDS OF OUR INDUSTRY,
SALES OF OUR PRODUCTS MAY DECLINE.

     E.piphany's future success depends on its ability to address the rapidly
changing needs of its customers and potential customers. E.piphany must maintain
and improve its E.piphany E.4 System and the Octane 2000 suite of products and
develop new products that include new technological developments, keep pace with
products of its competitors and satisfy the changing requirements of its
customers. If E.piphany does not, it may not achieve market acceptance and it
may be unable to attract new customers. E.piphany may also lose existing
customers, to whom it seeks to sell additional software solutions and
professional services.

     To achieve increased market acceptance of its products, E.piphany must,
among other things, continue to:

     - improve and introduce new software solutions for reporting and analysis,
       distributed database marketing and e-commerce,

     - integrate Octane's offerings with the E.piphany E.4 System offerings,

     - improve the effectiveness of its software, particularly in
       implementations involving very large databases and large numbers of
       simultaneous users,

     - enhance its software's ease of administration,

     - improve its software's ability to extract data from existing software
       systems, and

     - adapt to rapidly changing computer operating system and database
       standards and Internet technology.

     E.piphany may not be successful in developing and marketing these or other
new or improved products. If E.piphany is not successful, it may lose sales to
competitors.

     In addition, E.piphany has entered into customer contracts which contain
specific performance goals relating to new product releases or enhancements, and
if we are not able to meet these goals, we may be required to, among other
things, return fees, pay damages and offer discounts.

                                       23
<PAGE>   30

IF E.PIPHANY'S PRODUCTS DO NOT STAY COMPATIBLE WITH CURRENTLY POPULAR SOFTWARE
PROGRAMS, WE MAY LOSE SALES AND REVENUES.

     The E.piphany E.4 System and the Octane 2000 suite of products must work
with commercially available software programs that are currently popular. If
these software programs do not remain popular, or E.piphany does not update its
software to be compatible with newer versions of these programs, E.piphany may
lose customers.

     In order to operate the E.piphany E.4 System or the Octane 2000 suite of
products, each of these systems must be installed on both a computer server
running the Microsoft Windows NT or Windows 2000 computer operating systems and
a computer server running database software from Microsoft or Oracle. E.piphany
and Octane are each currently modifying their respective software to also
operate on UNIX operating systems and IBM DB2 databases. If we fail to
successfully complete these modifications in a timely manner, E.piphany may lose
sales and revenues. In addition, users access the E.piphany E.4 System and
certain of Octane's products through standard Internet browsers such as
Microsoft Internet Explorer. If we fail to obtain access to developer versions
of these software products, we may be unable to build and enhance our products
on schedule.

     After installation, each of the E.piphany E.4 System and the Octane 2000
suite of products collects and analyzes data to profile customers'
characteristics and preferences. This data may be stored in a variety of our
customers' existing software systems, including leading systems from Oracle,
PeopleSoft, Siebel Systems, SAP and Vantive, running on a variety of computer
operating systems. If E.piphany fails to enhance its software to collect data
from new versions of these products, it may lose potential customers. If it
loses customers, E.piphany's revenues and profitability may be harmed.

IF DATABASE ACCESS BECOMES STANDARDIZED, DEMAND FOR E.PIPHANY'S PRODUCTS WILL BE
REDUCED.

     E.piphany's products are useful for integrating data from a variety of
disparate data sources. Adoption of uniform, industry-wide standards across
various database and analytic software programs could minimize the importance of
the data integration capabilities of our products. This, in turn, could
adversely affect the competitiveness and market acceptance of E.piphany's
products. Also, a single competitor in the market for database and analytic
software programs or Internet relationship management may become dominant, even
if there is no formal industry-wide standard. If large numbers of E.piphany's
customers adopt a single standard, this would similarly reduce demand for
E.piphany's product. If E.piphany loses customers because of the adoption of
standards, E.piphany may have lower revenues and profitability.

E.PIPHANY'S AND OCTANE'S PRODUCTS HAVE LONG SALES CYCLES WHICH MAKES IT
DIFFICULT TO PLAN EXPENSES AND FORECAST RESULTS.

     It takes E.piphany between three and six months to complete the majority of
its sales, but it can take E.piphany up to one year or longer. Octane faces
similar sales cycles. It is therefore difficult to predict the quarter in which
a particular sale will occur and to plan expenditures accordingly. The period
between initial contact with a potential customer and their purchase of products
and services is relatively long due to several factors, including:

     - the complex nature of our products,

     - our need to educate potential customers about the uses and benefits of
       its products,

     - the purchase of our products requires a significant investment of
       resources by a customer,

     - our customers have budget cycles which affect the timing of purchases,

     - many of E.piphany's customers require competitive evaluation and internal
       approval before purchasing E.piphany's products,

                                       24
<PAGE>   31

     - potential customers may delay purchases due to announcements or planned
       introductions of new products by E.piphany or its competitors, and

     - many of E.piphany customers are large organizations which may require a
       long time to make decisions.

     The delay or failure to complete sales in a particular quarter could reduce
E.piphany's revenues in that quarter, as well as subsequent quarters over which
revenues for the sale would likely be recognized. If E.piphany's sales cycle
unexpectedly lengthens in general or for one or more large orders, it would
adversely affect the timing of its revenues. If E.piphany were to experience a
delay of several weeks on a large order, it could harm its ability to meet its
forecasts for a given quarter.

IF E.PIPHANY FAILS TO ESTABLISH, MAINTAIN OR EXPAND ITS RELATIONSHIPS WITH THIRD
PARTIES, OUR ABILITY TO GROW REVENUES COULD BE HARMED.

     In order to grow E.piphany's business, we must generate, retain and
strengthen relationships with third parties. To date, E.piphany has established
relationships with several companies, including consulting organizations and
system integrators that implement E.piphany's software, including Cambridge
Technology Partners, Ernst & Young and KPMG; resellers, including Acxiom,
Harte-Hanks and Pivotal; and application service providers that provide access
to E.piphany's software to their customers over the Internet, including Corio,
Exactis.com, Bullseye Interactive and Interrelate. Similarly, Octane has also
entered into reseller agreements with several companies including TeleTech,
Eltrax, RISC Management, e-Assist.com, Brigade Solutions, e-Convergent, and
MISNet. If the third parties with whom E.piphany and Octane have relationships
do not provide sufficient, high-quality service or integrate and support our
software correctly, our revenues may be harmed. In addition, the third parties
with whom we have relationships may offer products of other companies, including
products that compete with our products. We typically enter into contracts with
third parties that generally set out the nature of our relationships. However,
our contracts do not require these third parties to devote resources to
promoting, selling and supporting our products. Therefore we have little control
over these third parties. We cannot assure you that we can generate and maintain
relationships that offset the significant time and effort that are necessary to
develop these relationships.

     E.piphany must also effectively take advantage of the resources and
expertise of third parties to help it develop the E.piphany E.4 System and the
Octane 2000 product suite. Our agreements with third parties do not require them
to help us develop new software. If we fail to effectively work with third
parties, our ability to increase revenues by broadening our software solution
offerings, particularly in additional specific industries, will be limited.

IF THE COMBINED COMPANY FAILS TO EXPAND ITS DIRECT AND INDIRECT SALES CHANNELS,
WE WILL NOT BE ABLE TO INCREASE REVENUES.

     In order to grow its business, E.piphany needs to increase market awareness
and sales of its and Octane's products and services. To achieve this goal,
E.piphany needs to increase both its direct and indirect sales channels. If
E.piphany fails to do so, this failure could harm its ability to increase
revenues. E.piphany and Octane currently receive substantially all of their
revenues from direct sales, but we intend to increase sales through indirect
sales channels in the future. We also need to expand our direct sales force by
hiring additional salespersons and sales management.

     We intend to derive revenues from indirect sales channels by selling our
software through value added resellers. These resellers offer our software
products to their customers together with consulting and implementation services
or integrate our software solutions with other software. We also intend to
increasingly offer our software through application service providers, who
install our software on their

                                       25
<PAGE>   32

own computer servers and charge their customers for access to that software. We
need to expand our indirect sales channels by entering into additional
relationships with these third parties.

     E.piphany has not derived a material amount of revenues from international
sales to date, but we expect as part of our strategy to increase international
sales principally through the use of indirect sales channels. E.piphany will be
even more dependent on indirect sales channels in the future due to its
international strategy. E.piphany also plans to use international direct sales
personnel and therefore must hire additional sales personnel outside the United
States. E.piphany's ability to develop and maintain these channels will
significantly affect its ability to penetrate international markets.

E.PIPHANY HAS GROWN VERY QUICKLY AND IF E.PIPHANY FAILS TO MANAGE ITS GROWTH,
ITS ABILITY TO GENERATE NEW REVENUES AND ACHIEVE PROFITABILITY WOULD BE HARMED.

     E.piphany has grown significantly since its inception and will need to grow
quickly in the future. Any failure to manage this growth could impede
E.piphany's ability to increase revenues and achieve profitability. E.piphany
has increased its number of employees from 21 at December 31, 1997 to 333 as of
March 31, 2000. Following the acquisition of Octane, E.piphany expects to have
over 500 employees. The acquisition of Octane and future expansion could be
expensive and strain E.piphany's management and other resources. In order to
manage growth effectively, E.piphany must:

     - hire, train and integrate new personnel,

     - continue to augment its financial and accounting systems,

     - manage its sales operations, which are in several locations, and

     - expand its facilities.

IF OTHERS CLAIM THAT WE ARE INFRINGING THEIR INTELLECTUAL PROPERTY, WE COULD
INCUR SIGNIFICANT EXPENSES OR BE PREVENTED FROM SELLING OUR PRODUCTS.

     E.piphany cannot assure you that others will not claim that the combined
company is infringing their intellectual property rights or that we do not in
fact infringe those intellectual property rights. We have not conducted a search
for existing intellectual property registrations and we may be unaware of
intellectual property rights of others that may cover some of its technology.

     E.piphany has been contacted by a company which has asked E.piphany to
evaluate the need for a license of a patent the company holds directed to data
extraction technology. This company has filed litigation alleging infringement
of its patent against three of E.piphany's competitors. E.piphany cannot assure
you that the holder of the patent will not file litigation against E.piphany or
that E.piphany would prevail in the case of such litigation. In addition, the
patent holder has informed E.piphany that it has applications pending in
numerous foreign countries. The patent holder may also have applications on file
in the United States covering related subject matter which are confidential
until the patent is issued.

     Any litigation regarding intellectual property rights could be costly and
time-consuming and divert the attention of our management and key personnel from
its business operations. The complexity of the technology involved and the
uncertainty of intellectual property litigation increase these risks. Claims of
intellectual property infringement might also require us to enter into costly
royalty or license agreements.

     However, we may not be able to obtain royalty or license agreements on
terms acceptable to it, or at all. We also may be subject to significant damages
or an injunction against use of its products. A successful claim of patent or
other intellectual property infringement against us would have an immediate
material adverse effect on its business and financial condition.

                                       26
<PAGE>   33

     In addition, in all of Octane's software license agreements, Octane has
agreed to indemnify its customers against losses attributable to intellectual
property infringement by Octane's software. Should a third party claim that
Octane infringes their intellectual property, E.piphany could incur substantial
costs in defending and resolving such claims.

IF WE ARE UNABLE TO PROTECT ITS INTELLECTUAL PROPERTY RIGHTS, THIS INABILITY
COULD WEAKEN OUR COMPETITIVE POSITION, REDUCE ITS REVENUES AND INCREASE ITS
COSTS.

     The success of the combined company depends in large part on its
proprietary technology. We rely on a combination of patent, copyright, trademark
and trade secrets, confidentiality procedures and licensing arrangements to
establish and protect its proprietary rights. We may be required to spend
significant resources to monitor and police its intellectual property rights. If
we fail to successfully enforce its intellectual property rights, its
competitive position may be harmed.

     Our pending patent and trademark registration applications may not be
allowed or competitors may successfully challenge the validity or scope of these
registrations. In addition, our patents may not provide a significant
competitive advantage.

     Other software providers could copy or otherwise obtain and use our
products or technology without authorization. They also could develop similar
technology independently which may infringe our proprietary rights. We may not
be able to detect infringement and may lose a competitive position in the market
before it does so. In addition, competitors may design around our technology or
develop competing technologies. The laws of some foreign countries do not
protect proprietary rights to the same extent as do the laws of the United
States.

     In addition, one of the ways in which we charge for our software is based
on the number of users at a particular site that will be permitted to use the
software. Organizations that have a site license for a fixed number of users for
E.piphany products could allow unauthorized use of our software by unlicensed
users. Unauthorized use is difficult to detect and, to the extent that
E.piphany's software is used without authorization, we may lose potential
license fees.

PRIVACY AND SECURITY CONCERNS, PARTICULARLY RELATED TO THE USE OF OUR SOFTWARE
ON THE INTERNET, MAY LIMIT THE EFFECTIVENESS OF AND REDUCE THE DEMAND FOR
E.PIPHANY'S PRODUCTS.

     The effectiveness of our software products relies on the storage and use of
customer data collected from various sources, including information collected on
Web sites, as well as other data derived from customer registrations, billings,
purchase transactions and surveys. Our collection and use of such data for
customer profiling may raise privacy and security concerns. Our customers
generally have implemented security measures to protect customer data from
disclosure or interception by third parties. However, the security measures may
not be effective against all potential security threats. If a well publicized
breach of customer data security were to occur, our software products may be
perceived as less desirable, impacting our future sales and profitability.

     In addition, due to privacy concerns, some Internet commentators, consumer
advocates, and governmental or legislative bodies have suggested legislation to
limit the use of customer profiling technologies. The European Union and some
European countries have already adopted some restrictions on the use of customer
profiling data. In addition, Internet users can, if they choose, configure their
Web browsers to limit the collection of user data for customer profiling. Should
many Internet users choose to limit the use of customer profiling technologies,
or if major countries or regions adopt legislation or other restrictions on the
use of customer profiling data, E.piphany's software would be less useful to
customers, and E.piphany's sales and profits could decrease.

                                       27
<PAGE>   34

E.PIPHANY'S AND OCTANE'S PRODUCTS ARE NEW, AND IF THEY CONTAIN DEFECTS OR OUR
SERVICES ARE NOT PERCEIVED AS HIGH QUALITY, WE COULD LOSE POTENTIAL CUSTOMERS OR
BE SUBJECT TO DAMAGES.

     E.piphany began shipping its first products in early 1998, and in June
1999, began shipping its E.piphany E.4 System software. Octane began shipping
its current software product in February 2000. These products are complex and
may contain currently unknown errors, defects or failures, particularly since
they are new and recently released. In the past we have discovered software
errors in some of its products after introduction. We may not be able to detect
and correct errors before releasing its products commercially. If its commercial
products contain errors, E.piphany may be required to:

     - expend significant resources to locate and correct the error,

     - delay introduction of new products or commercial shipment of products, or

     - experience reduced sales and harm to its reputation from dissatisfied
       customers.

     Our customers also may encounter system configuration problems which
require us to spend additional consulting or support resources to resolve these
problems.

     In addition, E.piphany's customers generally store their data across
computer networks, which are often connected to the Internet. E.piphany's
software operates across its customers' computer networks and can, at the
customer's option, be accessed through an Internet connection. E.piphany
software contains technology designed to prevent theft or loss of data.
Nevertheless, customers may encounter security issues with their existing
databases installed across networks, particularly the Internet, or with
E.piphany's software. A security breach involving E.piphany's software, or a
widely publicized security breach involving the Internet generally, could harm
E.piphany's sales. A security breach involving E.piphany's software could also
expose E.piphany to claims for damages.

     Because E.piphany's software products are used for important
decision-making processes and Octane's software products enable our customers to
interact with their customers, product defects may also give rise to product
liability claims. Although E.piphany's license agreements with customers
typically contain provisions designed to limit E.piphany's exposure, some courts
may not enforce all or part of these limitations. Although E.piphany has not
experienced any product liability claims to date, it may encounter these claims
in the future. Product liability claims, whether or not successful, could:

     - divert the attention of E.piphany's management and key personnel from
       E.piphany's business,

     - be expensive to defend, and

     - result in large damage awards.

     E.piphany's product liability insurance may not be adequate to cover all of
the expenses resulting from a claim. In addition, if E.piphany's customers do
not find E.piphany's services to be of high quality, they may elect to use other
training, consulting and product integration firms rather than contract for
E.piphany's services. If customers are dissatisfied with E.piphany's services,
E.piphany may lose revenues.

E.PIPHANY INTENDS TO EXPAND ITS INTERNATIONAL SALES EFFORTS BUT WE DO NOT HAVE
SUBSTANTIAL EXPERIENCE IN INTERNATIONAL MARKETS.

     Although E.piphany's international sales have been immaterial to date,
E.piphany intends to expand its international sales efforts in the future.
E.piphany has limited experience in marketing, selling and supporting its
products and services abroad. If E.piphany is unable to grow its international
operations successfully and in a timely manner, its business and operating
results could

                                       28
<PAGE>   35

be seriously harmed. In addition, doing business internationally involves
greater expense and many additional risks, particularly:

     - unexpected changes in regulatory requirements, taxes, trade laws and
       tariffs,

     - differing intellectual property rights,

     - differing labor regulations,

     - unexpected changes in regulatory requirements,

     - changes in a specific country's or region's political or economic
       conditions,

     - greater difficulty in establishing, staffing and managing foreign
       operations, and

     - fluctuating exchange rates.

     E.piphany plans to expand its international operations in the near future,
and this will require a significant amount of attention from E.piphany's
management and substantial financial resources. E.piphany has begun its efforts
at international expansion in Europe and, as of March 31, 2000, including
RightPoint's international presence, had nine sales and marketing professionals
located in the United Kingdom and France. Octane has sales operations based in
the United Kingdom, Australia, and Germany including 23 professionals employed
in those locations. E.piphany is also exploring other regions for future
expansion.

IF E.PIPHANY ACQUIRES ADDITIONAL COMPANIES OR TECHNOLOGIES IN THE FUTURE, THEY
COULD PROVE DIFFICULT TO INTEGRATE, DISRUPT E.PIPHANY'S BUSINESS, DILUTE
STOCKHOLDER VALUE OR ADVERSELY AFFECT E.PIPHANY'S OPERATING RESULTS.

     In addition to the acquisition of Octane, E.piphany may acquire or make
investments in other complementary companies, services and technologies in the
future. If E.piphany fails to properly evaluate and execute acquisitions and
investments, they may seriously harm E.piphany's business and prospects. To
successfully complete an acquisition, E.piphany must:

     - properly evaluate the technology,

     - accurately forecast the financial impact of the transaction, including
       accounting charges and transactions expenses,

     - integrate and retain personnel,

     - combine potentially different corporate cultures, and

     - effectively integrate products and research and development, sales,
       marketing and support operations.

     If E.piphany fails to do any of these, it may suffer losses or its
management may be distracted from E.piphany's day-to-day operations. In
addition, if E.piphany conducts acquisitions using convertible debt or equity
securities, existing stockholders may be diluted which could affect the market
price of E.piphany's stock.

SEASONAL TRENDS IN SALES OF BUSINESS SOFTWARE MAY AFFECT E.PIPHANY'S QUARTERLY
REVENUES.

     The market for business software has experienced seasonal fluctuations in
demand. The first and third quarters of the year have been typically
characterized by lower levels of revenue growth. E.piphany's believes that these
fluctuations are caused in part by customer buying patterns, which are
influenced by year-end budgetary pressures and by sales force commission
structures. As our revenues grow, we may experience seasonal fluctuations in our
revenues.

FUTURE SALES OF OUR COMMON STOCK, INCLUDING THOSE PURCHASED IN OUR INITIAL
PUBLIC OFFERING AND THOSE ISSUED IN THE MERGER, MAY DEPRESS OUR STOCK PRICE.

     If our stockholders or optionees sell substantial amounts of our common
stock in the public market, the market price of our common stock could fall. In
addition, such sales could create the perception to the public of difficulties
or problems with our products and services. As a result, these sales also might
make it more difficult for us to sell equity or equity-related securities in the
future at a time and price that we deem appropriate.

     On April 14, 2000, we had 32,444,364 shares of common stock outstanding. Of
these shares, 31,182,693 are currently available for sale in the public market,
20,515,245 of which first became freely tradeable on April 20, 2000. In
addition, we will issue up to approximately 12,800,000 freely tradable shares to
Octane's shareholders in the merger. The remaining outstanding shares of
E.piphany's common stock will become eligible for sale in the public market as
follows:

<TABLE>

</TABLE>

     The above table excludes options and warrants (including those assumed in
the merger). Shares issued upon the exercise of outstanding options (including
those assumed in the merger) may generally also be sold in the public market.
E.piphany and its underwriters may remove the lock-up restrictions in advance
without prior notice.

E.PIPHANY DOES NOT INTEND TO PAY DIVIDENDS, YOU WILL NOT RECEIVE FUNDS WITHOUT
SELLING SHARES AND YOU MAY LOSE THE ENTIRE AMOUNT OF YOUR INVESTMENT.

     E.piphany has never declared or paid any cash dividends on its capital
stock and does not intend to pay dividends in the foreseeable future. E.piphany
intends to invest its future earnings, if any, to fund our growth. Therefore,
you will not receive any funds without selling your shares. We further cannot
assure you that you will receive a return on your investment when you sell your
shares or that you will not lose the entire amount of your investment.

BECAUSE SOME EXISTING STOCKHOLDERS TOGETHER OWN 22.4% OF E.PIPHANY'S STOCK, THE
VOTING POWER OF OTHER STOCKHOLDERS MAY BE LIMITED.

     After the closing of the merger, it is anticipated that E.piphany's
officers, directors and five percent or greater stockholders will beneficially
own or control, directly or indirectly, approximately 10,220,773 shares of
common stock, which in the aggregate represented approximately 22.4% of the
outstanding shares of common stock. As a result, if some of these persons or
entities act together, they may have the ability to control matters submitted to
E.piphany's stockholders for approval, including the election and removal of
directors and the approval of any business combination. This may delay or
prevent an acquisition or cause the market price of E.piphany's stock to
decline. Some of these persons or entities may have interests different than
yours. For example, they may be more interested in selling E.piphany to an
acquiror than other investors or may want E.piphany to pursue strategies that
are different from the wishes of other investors.

PROVISIONS IN E.PIPHANY'S CHARTER DOCUMENTS AND DELAWARE LAW MAY DELAY OR
PREVENT AN ACQUISITION OF E.PIPHANY.

     E.piphany's certificate of incorporation and bylaws contain provisions
which could make it harder for a third party to acquire E.piphany without the
consent of E.piphany's board of directors. For example, if a potential acquiror
were to make a hostile bid for E.piphany, the acquiror would not be able to call
a special meeting of stockholders to remove E.piphany's board of directors or
act by written consent without a meeting. In addition, E.piphany's board of
directors has staggered terms, which makes it difficult to remove them all at
once. The acquiror would also be required to provide advance notice of its
proposal to remove directors at an annual meeting. The acquiror also will not be
able to cumulate votes at a meeting, which will require the acquiror to hold
more shares to gain representation on the board of directors than if cumulative
voting were permitted.

     E.piphany's board of directors also has the ability to issue preferred
stock which would significantly dilute the ownership of a hostile acquiror. In
addition, Section 203 of the Delaware General Corporation Law limits business
combination transactions with 15% stockholders that have not been approved by
the board of directors. These provisions and other similar provisions make it
more difficult for a third party to acquire E.piphany without negotiation. These
provisions may apply even if the offer may be considered beneficial by some
stockholders.

     E.piphany's board of directors could choose not to negotiate with an
acquiror that it did not feel was in the strategic interests of E.piphany. If
the acquiror was discouraged from offering to acquire E.piphany or prevented
from successfully completing a hostile acquisition by the antitakeover measures,
you could lose the opportunity to sell your shares at a favorable price.

                         THE E.PIPHANY SPECIAL MEETING

DATE, TIME AND PLACE OF MEETING

     The special meeting of the stockholders of E.piphany will be held at the
Hotel Sofitel located at 223 Twin Dolphin Drive, Redwood City, California 94065,
on May 31, 2000, at 9:00 a.m., local time.

PURPOSE OF THE SPECIAL MEETING

     At the special meeting, E.piphany stockholders will consider and vote upon
a proposal to issue shares of E.piphany common stock to shareholders of Octane
in connection with the merger of a wholly-owned subsidiary of E.piphany into
Octane.

     E.piphany stockholders will also be asked to consider and vote upon such
other matters as may be properly submitted at the special meeting. Additionally,
E.piphany stockholders may be asked to vote upon a proposal to adjourn or
postpone the special meeting. Any adjournment or postponement could be used for
the purpose of allowing additional time for soliciting additional votes to
approve the proposed issuance of shares of E.piphany common stock in connection
with the merger.

     THE E.PIPHANY BOARD HAS UNANIMOUSLY APPROVED THE MERGER, THE MERGER
AGREEMENT AND THE PROPOSED ISSUANCE OF SHARES OF E.PIPHANY COMMON STOCK TO
OCTANE SHAREHOLDERS IN CONNECTION WITH THE MERGER, AND BELIEVES THAT THE TERMS
OF THE MERGER, THE MERGER AGREEMENT AND THE ISSUANCE OF THE SHARES ARE FAIR TO,
AND IN THE BEST INTERESTS OF, E.PIPHANY AND ITS STOCKHOLDERS, AND UNANIMOUSLY
RECOMMENDS THAT HOLDERS OF SHARES OF E.PIPHANY STOCK VOTE "FOR" THE PROPOSED
ISSUANCE OF SHARES OF E.PIPHANY COMMON STOCK TO OCTANE SHAREHOLDERS IN
CONNECTION WITH THE MERGER.

RECORD DATE; VOTING RIGHTS; PROXIES

     Only holders of E.piphany capital stock at the close of business on April
14, 2000, the record date, are entitled to notice of and to vote at the special
meeting.

     As April 14, 2000, there were 32,444,364 shares of E.piphany common stock
issued and outstanding.

     The accompanying form of proxy is for use at the special meeting if a
stockholder will be unable to attend the special meeting. All shares of
E.piphany common stock represented by properly executed proxies will, unless
such proxies have been previously revoked, be voted in accordance with the
instructions indicated in such proxies. IF NO INSTRUCTIONS ARE INDICATED, SHARES
OF E.PIPHANY COMMON STOCK REPRESENTED BY SUCH PROXIES WILL BE VOTED "FOR" THE
ISSUANCE OF SHARES OF E.PIPHANY COMMON STOCK TO OCTANE SHAREHOLDERS IN
CONNECTION WITH THE MERGER OF A WHOLLY-OWNED SUBSIDIARY OF E.PIPHANY INTO
OCTANE. E.piphany does not know of any matters other than as described in the
notice of special meeting of stockholders that are to come before the special
meeting. If any other matter is properly presented for action at the special
meeting, the persons named in the enclosed form of proxy will have the
discretion to vote on such matters in accordance with their best judgment.

     A stockholder who has given a proxy may revoke it at any time prior to its
exercise by giving written notice to the Assistant Secretary of E.piphany, by
signing and returning a later-dated proxy, or by voting in person at the special
meeting. However, mere attendance at the special meeting will not in and of
itself have the effect of revoking the proxy. Votes cast by proxy or in person
at the special meeting will be tabulated by the inspector of election appointed
for the special meeting.

SOLICITATION OF PROXIES

     Proxies are being solicited by and on behalf of the E.piphany board of
directors. E.piphany will bear all expenses in connection with such
solicitation. In addition to solicitation by use of the mails, proxies may be
solicited by directors, officers and employees of E.piphany in person or by
telephone,

                                       34
<PAGE>   41

telegram or other means of communication. Such directors, officers and employees
will not be additionally compensated for, but may be reimbursed by E.piphany for
out-of-pocket expenses incurred in connection with, such solicitation.
Arrangements have also been made with brokerage firms, banks, custodians,
nominees and fiduciaries for the forwarding of proxy and solicitation materials
to owners of E.piphany common stock held of record by such persons, and these
firms will be reimbursed for reasonable expenses incurred in forwarding the
proxy and solicitation materials.

QUORUM; ABSTENTIONS; BROKER NON-VOTES

     The presence in person or by properly executed proxy of holders of a
majority of all the issued and outstanding shares of E.piphany common stock
entitled to vote is necessary to constitute a quorum at the special meeting. For
purposes of determining whether a quorum is present, the inspector of election
will include shares that are present or represented by proxy, even if the
holders of such shares abstain from voting on any particular matter. In the
event that a broker, bank, custodian, nominee or other record holder of
E.piphany common stock indicates on a proxy that it does not have discretionary
authority to vote certain shares on a particular proposal -- known as a broker
non-vote -- those shares will not be considered for purposes of determining the
number of shares entitled to vote with respect to a particular proposal on which
the broker has expressly not voted, but will be counted for purposes of
determining the presence or absence of a quorum for the transaction of business.
Accordingly, abstentions and broker non-votes will not affect the outcome of the
voting on a proposal that requires a majority of the shares entitled to vote
thereon.

REQUIRED VOTE

     Pursuant to rules promulgated by the National Association of Securities
Dealers relating to the Nasdaq Stock Market, E.piphany stockholders are required
to approve the issuance of shares of E.piphany common stock to the Octane
shareholders in connection with the merger because the number of shares of
E.piphany common stock to be issued will be in excess of 20% of the number of
shares of E.piphany common stock outstanding immediately prior to the proposed
issuance of shares. The approval of the issuance of shares of E.piphany common
stock to the Octane shareholders requires the affirmative vote of the holders of
a majority of the shares of E.piphany common stock present or represented at the
E.piphany special meeting of stockholders. For all purposes, each share of
E.piphany common stock entitles the holder thereof to one vote per share.

     For purposes of determining whether the proposed issuance of shares of
E.piphany common stock to the Octane shareholders has been approved, the
inspector of election will include abstentions and broker non-votes as a portion
of the number of shares deemed to have voted on such matters at the special
meeting. Accordingly, abstentions and broker non-votes will have the effect of a
"no" vote on the proposal to approve the proposed issuance of shares of
E.piphany common stock in connection with the merger.

     As of April 14, 2000, directors and executive officers of E.piphany and
their affiliates were beneficial owners of an aggregate of 10,220,773 shares of
E.piphany common stock, or approximately 31.1% of the outstanding shares of
common stock.

     All of the E.piphany directors, executive officers and certain of their
affiliates have entered into agreements to vote all shares of E.piphany capital
stock beneficially owned by them in favor of the proposed issuance of shares of
E.piphany common stock to the Octane shareholders in connection with the merger.

     The matters to be considered at the special meeting are of great importance
to the stockholders of E.piphany. Accordingly, stockholders are urged to read
and carefully consider the information presented in the proxy
statement/prospectus, and to complete, date, sign and promptly return the
enclosed proxy in the enclosed postage-paid envelope.

                           THE OCTANE SPECIAL MEETING

DATE, TIME AND PLACE OF MEETING

     The special meeting of the shareholders of Octane will be held at the
offices of Octane located at 2929 Campus Drive #101, San Mateo, California
94403, on May 31, 2000, at 8:00 a.m., local time.

PURPOSE OF THE SPECIAL MEETING

     At the special meeting, Octane shareholders will consider and vote upon:

     - a proposal to approve the merger agreement and the merger, and

     - a proposal that all Octane preferred stock be converted into Octane
       common stock immediately prior to the closing.

     Octane shareholders will also be asked to consider and vote upon such other
matters as may be properly submitted at the special meeting. Additionally,
Octane shareholders may be asked to vote upon a proposal to adjourn or postpone
the special meeting. Any adjournment or postponement could be used for the
purpose of allowing additional time for soliciting additional votes to approve
the merger agreement and the conversion of the Octane preferred stock.

     THE OCTANE BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT, THE MERGER
AND THE PREFERRED STOCK CONVERSION, BELIEVES THAT THE TERMS OF THE MERGER
AGREEMENT, THE MERGER AND THE PREFERRED STOCK CONVERSION ARE FAIR TO, AND IN THE
BEST INTERESTS OF, OCTANE AND ITS SHAREHOLDERS, AND UNANIMOUSLY RECOMMENDS THAT
HOLDERS OF SHARES OF OCTANE STOCK VOTE "FOR" ADOPTION AND APPROVAL OF THE MERGER
AGREEMENT, THE MERGER AND THE PREFERRED STOCK CONVERSION.

RECORD DATE; VOTING RIGHTS; PROXIES

     Only holders of Octane capital stock at the close of business on April 14,
2000, the record date, are entitled to notice of and to vote at the special
meeting.

     As of April 14, there were 9,729,189 shares of Octane common stock issued
and outstanding, and 12,951,320 shares of Octane preferred stock issued and
outstanding.

     The accompanying form of proxy is for use at the special meeting if a
shareholder will be unable to attend the special meeting. All shares of Octane
common stock and preferred stock represented by properly executed proxies will,
unless such proxies have been previously revoked, be voted in accordance with
the instructions indicated in such proxies. IF NO INSTRUCTIONS ARE INDICATED,
SHARES OF OCTANE COMMON STOCK AND PREFERRED STOCK REPRESENTED BY SUCH PROXIES
WILL BE VOTED "FOR" ADOPTION AND APPROVAL OF THE MERGER AGREEMENT AND THE MERGER
AND "FOR" THE PREFERRED STOCK CONVERSION. Octane does not know of any matters
other than as described in the notice of special meeting of shareholders that
are to come before the special meeting. If any other matter is properly
presented for action at the special meeting, the persons named in the enclosed
form of proxy will have the discretion to vote on such matters in accordance
with their best judgment.

     A shareholder who has given a proxy may revoke it at any time prior to its
exercise by giving written notice to the Secretary of Octane, by signing and
returning a later-dated proxy, or by voting in person at the special meeting.
However, mere attendance at the special meeting will not in and of itself have
the effect of revoking the proxy. Votes cast by proxy or in person at the
special meeting will be tabulated by the inspector of election appointed for the
special meeting.

SOLICITATION OF PROXIES

     Proxies are being solicited by and on behalf of the Octane board of
directors. Octane will bear all expenses in connection with such solicitation.
In addition to solicitation by use of the mails, proxies may be solicited by
directors, officers and employees of Octane in person or by telephone, telegram
or other means of communication. Such directors, officers and employees will not
be additionally compensated for, but may be reimbursed by Octane for
out-of-pocket expenses incurred in connection with, such solicitation.

QUORUM; ABSTENTIONS

     The presence in person or by properly executed proxy of holders of a
majority of all the issued and outstanding shares of Octane common stock and
preferred stock entitled to vote is necessary to constitute a quorum at the
special meeting. While there is no definitive statutory or case law authority in
California as to the proper treatment of abstentions, Octane believes that
abstentions should be counted for purposes of determining the presence or
absence of a quorum for the transaction of business, but should not be counted
for purposes of determining the number of shares entitled to vote on a
particular proposal as the shareholder has expressly declined to vote on the
proposal. Accordingly, abstentions and broker non-votes will not affect the
outcome of the voting on a proposal that requires a majority of the shares
entitled to vote thereon.

REQUIRED VOTE

     Adoption and approval of the merger agreement and the merger requires the
affirmative vote of the holders of a majority of the outstanding shares of
Octane common stock, a majority of the outstanding shares of Octane preferred
stock, and a majority of the outstanding shares of Octane common stock and
preferred stock voting together as a single class.

     Approval of the preferred stock conversion requires the affirmative vote of
the holders of 66 2/3% of the outstanding shares of Octane preferred stock.

     For all purposes, each share of Octane common stock entitles the holder
thereof to one vote per share and each share of Octane preferred stock entitles
the holder thereof to one vote per share.

     For purposes of determining whether the merger, the merger agreement and
preferred stock conversion have been approved, the inspector of election will
include abstentions as a portion of the number of shares deemed to have voted on
such matters at the special meeting. Accordingly, abstentions will have the
effect of a "no" vote on the proposals to approve merger agreement, the merger
and preferred stock conversion.

     As of April 14, 2000, directors and executive officers of Octane and their
affiliates were beneficial owners of an aggregate of 7,271,360 shares of Octane
common stock and 9,626,519 shares of preferred stock, or approximately:

     - 74.7% of the outstanding shares of common stock, and

     - 74.3% of the outstanding shares of preferred stock.

     All of the Octane directors, executive officers, venture capital firms
affiliated with some of the Octane directors, and all other affiliates of Octane
have entered into agreements to vote all shares of Octane common stock and
preferred stock of Octane beneficially owned by them in favor of the merger, the

                   DISSENTERS' RIGHTS OF OCTANE SHAREHOLDERS

     THE FOLLOWING SUMMARY OF DISSENTERS' RIGHTS UNDER CALIFORNIA LAW IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO CHAPTER 13 OF THE CALIFORNIA GENERAL
CORPORATION LAW, THE COMPLETE TEXT OF WHICH IS ATTACHED HERETO AS ANNEX IV.

     FAILURE TO STRICTLY FOLLOW THE PROCEDURES SET FORTH IN CHAPTER 13 OF THE
CALIFORNIA CORPORATIONS CODE MAY RESULT IN THE LOSS, TERMINATION OR WAIVER OF
DISSENTERS' RIGHTS. AN OCTANE SHAREHOLDER WHO SIGNS A PROXY CARD APPROVING AND
AUTHORIZING THE MERGER AND THE MERGER AGREEMENT OR WHO RETURNS A BLANK EXECUTED
PROXY WILL NOT HAVE A RIGHT TO DISSENT FROM THE MERGER OR THE MERGER AGREEMENT.

     The rights of Octane shareholders who dissent in connection with the merger
are governed by specific legal provisions contained in Chapter 13 (Sections
1300 - 1312) of the California Corporations Code, the text of which is attached
as Annex IV hereto. The description of dissenters' rights contained in this
proxy statement/prospectus is qualified in its entirety by reference to those
sections of the California Corporations Code. FAILURE TO FOLLOW THE STEPS
REQUIRED BY CHAPTER 13 OF THE CALIFORNIA CORPORATIONS CODE FOR PERFECTING
DISSENTERS' RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.

     If the merger is completed, certain of the Octane shareholders who object
to the merger and who have fully complied with all applicable provisions of
Chapter 13 of the California Corporations Code may have the right to require
Octane to purchase the shares of Octane common stock held by them for cash at
the fair market value of those shares on the day before the terms of the merger
were first announced, excluding any appreciation or depreciation because of the
merger. Persons who are beneficial owners of shares of Octane common stock but
whose shares are held by another person, such as a broker or nominee, should
instruct the record holder to follow the procedures outlined below if such
persons wish to dissent with respect to any or all of their shares. Under the
California Corporations Code, no shareholder who is entitled to exercise
dissenters' rights has any right at law or in equity to attack the validity of
the merger or to have the merger set aside or rescinded, except in an action to
test whether the number of shares required to authorize or approve the merger
had been legally voted in favor of the merger.

     Shares of Octane common stock must be purchased by Octane upon demand from
a dissenting shareholder if all applicable requirements are complied with, but
only if (a) demands for payment are filed with respect to 5% or more of the
outstanding shares of such Octane common stock, or (b) the shares are subject to
a restriction on transfer imposed by Octane or by any law or regulation.

     Octane is not aware of any restriction on transfer of any of the shares of
Octane common stock except restrictions that may be imposed upon shareholders
who are deemed to be "affiliates" of Octane as that term is defined in Rule 144
under the Securities Act. Those shareholders who believe there is some such
restriction affecting their shares should consult with their own legal counsel
as to the nature and extent of any dissenters' rights they may have.

     For an Octane shareholder to exercise the right to have Octane purchase his
or her shares of Octane common stock, the procedures to be followed under
Chapter 13 of the California Corporations Code include the following
requirements:

     - The shareholder of record must have voted the shares against the merger.
       It is not sufficient to abstain from voting. However, the shareholder may
       abstain as to part of his or her shares or

                                       38
<PAGE>   45

       vote part of those shares for the merger without losing the right to have
       purchased those shares which were voted against the merger, and

     - Any such shareholder who voted against the merger, and who wishes to have
       his or her shares that were voted against the merger purchased by Octane,
       must make a written demand to have Octane purchase those shares for cash
       at their fair market value. The demand must include the information
       specified below and must be received by Octane or its transfer agent not
       later than the date of the Octane special meeting, which is May 31, 2000.

     Within ten days after the approval of the merger by Octane shareholders,
the respective holders of shares of Octane common stock who voted against the
merger and made a timely demand for purchase (and who are entitled to require
Octane to purchase their shares because either (a) holders of 5% or more of the
outstanding shares filed demands by the date of the Octane special meeting, or
(b) the shares are restricted as to transfer) must be notified by Octane of the
approval and Octane must offer all of these shareholders a cash price for their
shares that Octane considers to be the fair market value of the shares on the
day before the terms of the merger were first announced, excluding any
appreciation or depreciation because of the proposed merger. The notice also
must contain a brief description of the procedures to be followed under Chapter
13 of the California Corporations Code in order for a shareholder to exercise
the right to have Octane purchase his or her shares, including the 30-day time
period for submitting certificates representing shares as to which dissenters'
rights are being exercised, and attach a copy of the relevant provisions of the
California Corporations Code.

DEMAND FOR PURCHASE

     Merely voting or delivering a proxy directing a vote against the approval
of the merger does not constitute a demand for purchase. A written demand is
essential.

     In all cases, the written demand that the dissenting shareholder must
deliver to Octane must:

     - be made by the person who was the shareholder of record, including a
       transferee of record, on the Octane record date set for voting on the
       merger, April 14, 2000, or his or her duly authorized representative, and
       not by someone who is merely a beneficial owner of the shares,

     - state the number and class of dissenting shares, and

     - include a demand that Octane purchase the shares at what the shareholder
       claims to be the fair market value of such shares on the day before the
       terms of the merger were first announced, excluding any appreciation or
       depreciation because of the proposed merger. It is Octane's position that
       this day is March 14, 2000. A shareholder may take the position in the
       written demand that a different date is applicable. The shareholder's
       statement of fair market value constitutes an offer by such dissenting
       shareholder to sell the shares to Octane at such price.

     In addition, it is recommended that the following conditions be complied
with to ensure that the demand is properly executed and delivered:

     - the demand should be sent by registered or certified mail, return receipt
       requested,

     - the demand should be signed by the shareholder of record, or his or her
       duly authorized representative, exactly as his or her name appears on the
       stock certificates evidencing the shares,

     - a demand for the purchase of shares owned jointly by more than one person
       should identify and be signed by all such holders, and

     - any person signing a demand for purchase in any representative
       capacity -- such as attorney-in-fact, executor, administrator, trustee or
       guardian -- should indicate his or her title and, if

                                       39
<PAGE>   46

       Octane so requests, furnish written proof of his or her capacity and
       authority to sign the demand.

     A shareholder may not withdraw a demand for payment without the consent of
Octane. Under the terms of the California Corporations Code, a demand by a
shareholder is not effective for any purchase unless it is received by Octane
(or any transfer agent thereof).

OTHER REQUIREMENTS

     Within 30 days after the date on which the notice of the approval of the
merger is mailed by Octane to its shareholders, the shareholders' certificates
representing any shares which any shareholder demands be purchased must be
submitted to Octane at its principal office, or at the office of any transfer
agent thereof, to be stamped with a statement that the shares are dissenting
shares. Upon subsequent transfer of these shares, the new certificates will be
similarly stamped, together with the name of the original dissenting
shareholder.

     If Octane and a dissenting shareholder agree that the shares held by such
shareholder are eligible for dissenters' rights and agree upon the price of such
shares, the dissenting shareholder is entitled to receive from Octane the agreed
price with interest thereon at the legal rate on judgments from the date of such
agreement. Any agreement fixing the fair market value of dissenting shares as
between Octane and the holders thereof must be filed with the Secretary of
Octane at the address set forth below. Subject to certain provisions of Section
1306 and Chapter 5 of the California Corporations Code, payment of the fair
market value of the dissenting shares shall be made within 30 days after the
amount thereof has been agreed upon or within 30 days after the statutory or
contractual conditions to the merger are satisfied, whichever is later. Cash
dividends declared and paid by Octane upon the dissenting shares after the date
of approval of the merger by its shareholders and prior to payment for the
shares shall be credited against the total amount to be paid by Octane.

     If Octane and a dissenting shareholder fail to agree on either the fair
market value of the shares or on the eligibility of the shares to be purchased,
then either the shareholder or Octane may file a complaint for judicial
resolution of the dispute in the superior court of the proper county. The
complaint must be filed within six months after the date on which the respective
notice of approval is mailed to the shareholders. If a complaint is not filed
within six months, the shares will lose their status as dissenting shares. Two
or more dissenting shareholders may join as plaintiffs or be joined as
defendants in such an action. If the eligibility of the shares is at issue, the
court will first decide this issue. If the fair market value of the shares is in
dispute, the court will determine, or shall appoint one or more impartial
appraisers to assist in its determination of the fair market value. The costs of
the action will be assessed or apportioned as the court considers equitable, but
if the fair market value is determined to exceed 125% of the price offered to
the shareholder, Octane will be required to pay such costs.

     Any demands, notices, certificates or other documents required to be
delivered to Octane may be sent to the Secretary, Octane Software, Inc., 2929
Campus Drive #101, San Mateo, CA 94403.

                      THE MERGER AND RELATED TRANSACTIONS

     The following discussion summarizes the proposed merger and related
transactions. The discussion is not, however, a complete statement of all
provisions of the merger agreement and related agreements. Detailed terms of and
conditions to the merger and related transactions are contained in the merger
agreement, a copy of which is attached to this proxy statement/prospectus as
Annex I. Statements made in this proxy statement/prospectus with respect to the
terms of the merger and related transactions are qualified in their respective
entireties by reference to, and you are urged to read the more detailed
information set forth in the merger agreement and the other documents attached
to the back of this proxy statement/prospectus.

BACKGROUND OF THE MERGER AND RELATED TRANSACTIONS

     E.piphany from time to time has evaluated entering into strategic
relationships with and strategic acquisitions of companies with complementary
businesses and technologies. Octane Software, Inc. has been growing its
organization, customer base and revenue and was preparing to file a registration
statement to conduct an initial public offering. Octane was also in the process
of developing strategic partnerships to complement its operational customer
relationship management solutions.

     In early 1999, Aditya (Tim) Guleri, Chairman of the Board of Directors,
Chief Executive Officer of Octane, and Roger Siboni, President and Chief
Executive Officer of E.piphany, became aware of each others' companies through
common acquaintances and business partners.

     In June 1999, Mr. Siboni and Mr. Guleri met at E.piphany's headquarters to
discuss their respective companies and strategies. The two executives agreed
that a strategic partnership would be beneficial to both companies in the
future.

     On November 11, 1999, Phil Fernandez, E.piphany's Executive Vice President
of Engineering and Paul Rodwick, E.piphany's Vice President of Product Marketing
and Strategy, met with Mr. Guleri and Kira Makagon, Octane's Chief Technical
Officer, at E.piphany's headquarters. They briefly discussed their respective
software products and how the two companies might work together. They agreed to
set up another meeting in which they could provide product demonstrations to
each other.

     On December 2, 1999, Mr. Rodwick and Don Fornes, E.piphany's Director of
Strategic Planning, met with Mr. Guleri and Tom Clark, Octane's Director of
Product Marketing, at Octane's headquarters. They provided each other with
product demonstrations and again discussed how the two companies might work
together.

     On January 26, 2000, Mr. Siboni and Mr. Guleri met at a local restaurant to
discuss the nature of the strategic partnership that was being discussed. At
that meeting, Mr. Siboni suggested that there could be merits to combining the
two companies. Both executives agreed that the idea should be pursued
concurrently with the development of a business relationship.

     On February 3, 2000, Mr. Siboni met with Mr. Guleri and David Strohm, a
member of the Octane Board of Directors, and continued the previous discussions
regarding the potential combination of the companies.

     On February 8, 2000, Mr. Rodwick and Mr. Fornes met with Todd Rowe,
Octane's Vice President of Business Development and John Diorio, a Product
Manager at Octane, at E.piphany's headquarters. The meeting focused on outlining
the growth strategies of both companies.

     On February 9, 2000, Mr. Rodwick, Mr. Fornes and Ron Barale, E.piphany's
Vice President of Application Development, met with Ms. Makagon, Mr. Rowe and
Mr. Diorio at Octane's headquarters. The meeting focused on technical aspects of
the Octane product and how best to integrate that product with E.piphany's
products.

                                       41

     On February 12, 2000, the executive teams of both companies met at
E.piphany's headquarters. At that meeting, Mr. Siboni made an informal
presentation to the senior Octane executives regarding the synergies and
strategic benefits that could accrue to both companies if a business combination
was effected. Mr. Siboni asked that serious discussions begin toward agreeing on
a business combination. Representatives of the two companies then discussed
their growth strategies and cultures and how the two companies might come
together in a business combination.

     Later on February 12, 2000, Octane's management proceeded to have internal
discussions, and, after a discussion with the Octane board of directors on
February 13, 2000, Octane agreed to engage in merger discussions with E.piphany.
At an informal meeting of the Octane board of directors on February 13, 2000,
the board discussed the retention of an investment banking firm to advise Octane
and its board of directors on the merger transaction, but a final decision to
proceed in this direction was not made.

     On February 13, 2000, valuation discussions began on an informal basis
between Mr. Siboni and Mr. Guleri.

     Between February 15, 2000 and March 15, 2000, Mr. Siboni met with Mr.
Guleri on numerous occasions to discuss the terms of a potential acquisition.
Some of these meetings included Kevin Yeaman, E.piphany's Chief Financial
Officer and James Doehrman, Octane's Chief Financial Officer.

     On February 16, 2000, senior executives from both companies met and
performed due diligence so that valuation discussions could be refined.

     On February 17, 2000, at the direction of E.piphany, a representative from
Credit Suisse First Boston reviewed mechanics of valuation calculation generally
with the Octane board of directors and senior executives. This meeting was
inconclusive and informal discussions about valuation metrics continued into the
next week.

     On February 18, 2000, at a regularly scheduled meeting of the E.piphany
board of directors, Mr. Siboni updated the board on the discussions with Octane
and other strategic alternatives available to E.piphany. The board directed
E.piphany's management to continue its discussions with Octane.

     On February 22, 2000, Mr. Guleri and Mr. Siboni reached tentative agreement
on the mechanics of the valuation calculation and that any E.piphany offer would
be presented as a fixed number of E.piphany shares based on a negotiated
ownership percentage to be held by Octane in the combined company. It was
further agreed that the share calculation would be based on the fully diluted
number of shares of E.piphany common stock outstanding at the latest practicable
date prior to the consummation of the merger.

     Due diligence meetings were held between various senior executives of both
companies during the weeks of February 21, 2000 and February 28, 2000. On
February 23, 2000, senior executives of Octane met with representatives of
Credit Suisse First Boston to discuss the financial advisor's due diligence
being conducted on behalf of E.piphany. Follow-up discussions were held during
the next several days.

     On February 26, 2000, Mr. Guleri had an informal meeting with Mr. Strohm
and Mr. Robert Davoli, another member of the Octane Board of Directors, and
discussed various other strategic alternatives, which included Octane's
continued pursuit of an initial public offering and possible business
combinations with other companies. The Octane board concluded that discussions
should continue between E.piphany and Mr. Guleri, and the board reached
agreement on the range of valuation that the Octane board of directors would
consider acceptable. All parties agreed that if consensus could not be achieved
within that valuation range within one week, Octane should continue to
aggressively pursue its initial public offering. The parties again discussed the
potential need for

                                       42
<PAGE>   49

Octane to hire an investment banking firm to advise it and its board of
directors on the transaction, but did not reach a final conclusion.

     On February 29, 2000, Mr. Strohm met with Mr. Siboni and had further
informal discussions on the valuation range that was acceptable to Octane and
conducted due diligence on behalf of the Octane board.

     On March 3, 2000, Mr. Siboni met with Mr. Guleri, and both began serious
discussions with an intent to reach a consensus on valuation so that drafting of
a definitive agreement of merger could begin. After lengthy discussions, Mr.
Siboni presented Mr. Guleri with a verbal offer for Octane that equaled
approximately 12.8 million shares of E.piphany common stock, or a 26.5% interest
in the combined companies. This offer was accepted verbally by Mr. Guleri. Both
parties agreed to begin negotiation of a definitive merger agreement.

     Negotiation of a definitive agreement of merger and legal due diligence
began on March 4, 2000. Shortly after negotiations began, the Octane board made
a final recommendation that Octane retain an investment banking firm to advise
Octane and its board of directors during the negotiations of the definitive
agreement of merger. On March 8, 2000, Octane contacted Morgan Stanley Dean
Witter and hired them to provide advisory services.

     Discussions about the final valuation continued on an informal basis until
both parties agreed on March 13, 2000 that the March 3, 2000 agreement of 12.8
million shares of E.piphany common stock, or 26.5% of the combined companies,
would be the final agreed valuation.

     On March 13, 2000 the Octane board received copies of the proposed merger
agreement.

     On March 14, 2000 the Octane board met again telephonically to discuss the
status of negotiations. Mr. Guleri discussed the status of key points in the
negotiation. Octane's legal counsel then advised the board of its fiduciary
obligations in considering a possible transaction with E.piphany, and reviewed
with the Octane board the terms of the proposed merger agreement and the status
of the negotiation on those terms. Representatives of Morgan Stanley Dean Witter
then further reviewed with the board its analysis of valuations of comparable
companies and comparable transactions and answered the board's questions about
comparable transactions. The board asked numerous questions of Morgan Stanley
Dean Witter and Octane's legal counsel, and a discussion ensued regarding open
issues and strategic alternatives. The board authorized Mr. Guleri and Mr.
Doehrman to proceed with negotiations toward finalizing the definitive agreement
subject to the satisfactory resolution of certain open issues and unanimously
voted to approve the merger.

     On March 14, 2000, the E.piphany board of directors met telephonically with
its legal counsel and financial advisors. Mr. Siboni, Mr. Yeaman and E.piphany's
legal counsel reviewed with the board the terms of the merger agreement and the
status of negotiations relating to those terms. Also at this meeting,
representatives of Credit Suisse First Boston reviewed with the board its
financial analysis with respect to the proposed merger consideration.
Representatives of Credit Suisse First Boston then rendered to the E.piphany
board an oral opinion, which opinion was subsequently confirmed by delivery of a
written opinion dated March 14, 2000, to the effect that, as of that date and
based on and subject to the matters described in its opinion, the consideration
provided for in the merger was fair, from a financial point of view, to
E.piphany. The board asked numerous questions and discussed the merits of the
transaction at length. After this discussion, the board unanimously voted to
approve the merger.

     The definitive agreement was signed during the evening of March 14, 2000
and a joint press release was issued by E.piphany and Octane announcing the
signing of the merger agreement on March 15, 2000.

JOINT REASONS FOR THE MERGER

     The boards of directors of E.piphany and Octane have each unanimously
approved the merger agreement and the merger, and each of the E.piphany and the
Octane board unanimously recommends approval of the merger agreement and the
merger by their respective stockholders. The boards of both companies have
identified a number of potential benefits which they believe will contribute to
the success of the combined company, including:

     - creation of a more complete solution that includes software for both
       analyzing customer data as well as automating customer interactions
       across all points of customer interaction,

     - enabling the combined company to respond more quickly and effectively to
       technological change, increased competition and market demands in an
       industry experiencing rapid innovation and change,

     - enabling the combined company to more effectively sell and market its
       solutions,

     - enabling the combined company to increase market penetration by selling
       both companies' solutions through both companies' sales and distribution
       channels, and

     - creation of a unified enterprise application platform, allowing the
       combined company to more effectively develop and market additional
       applications.

E.PIPHANY'S REASONS FOR THE MERGER

     The E.piphany board has unanimously approved the merger and has identified
several potential benefits of the merger that it believes will contribute to the
success of the combined entity following the merger. The E.piphany board
believes that Octane possesses technology that will be valuable to E.piphany's
product and service offerings. In the process of approving the merger, the
E.piphany board considered a number of factors, including:

     - the opportunity to enhance the E.piphany E.4 System with Octane's
       technology,

     - the ability to automate customer interactions in addition to analyzing
       customer data,

     - the ability to integrate multiple channels of customer interaction,
       including the Web, call center, email, fax and wireless devices,

     - the ability to offer a more complete solution to customers that are
       looking to reduce the number of vendors from which they have to purchase
       software products,

     - the opportunity to accelerate the development of other new product
       initiatives by utilizing the greater engineering resources of the
       combined company,

     - increased capacity across the entire organization through the addition of
       over 200 Octane employees,

     - the ability to cross-sell E.piphany's and Octane's products, thereby
       increasing revenue without a commensurate increase in selling costs, and

     - the extent to which the increased size of the combined company will
       enable it to compete with larger competitors.

     In the course of its deliberations, the E.piphany board reviewed a number
of additional factors relevant to the merger. These factors included:

     - information concerning the respective businesses, prospects, historical
       financial performance and conditions, operations, technologies,
       management, products, competitive positions, customers and future
       development plans of both E.piphany and Octane,

                                       44
<PAGE>   51

     - the terms of the merger agreement,

     - the likelihood of realizing superior benefits through alternative
       strategies,

     - the value of Octane as a part of E.piphany's operations,

     - the compatibility of management and businesses of E.piphany and Octane,
       and

     - results from E.piphany's management's due diligence investigation of
       Octane.

     The E.piphany board also considered a variety of potentially negative
factors in its deliberations concerning the merger. These factors include:

     - the potential loss of revenue from E.piphany's business following the
       merger as a result of confusion in the marketplace and the possible
       exploitation of such confusion by competitors of E.piphany,

     - the possibility of management distraction associated with the
       acquisition,

     - the risk that benefits sought to be achieved by the acquisition might not
       be realized,

     - accounting charges from the merger, and

     - the risks described above in the section entitled "Risk Factors."

     Additionally, in evaluating the proposed acquisition, the E.piphany board
of directors considered the pro forma contribution from Octane to revenue and
net losses of the combined company, both historically and in the near term.
Although based on such analyses the E.piphany board of directors concluded that
the acquisition would increase losses in the near term, for the strategic
reasons set forth above, the board unanimously determined that E.piphany should
proceed with the merger agreement and the merger.

     The preceding discussion of the information and factors considered by the
E.piphany board is not, and is not intended to be, exhaustive, but is believed
to include the material factors considered by the E.piphany board in evaluating
the merger and the issuance of shares of E.piphany common stock to Octane
shareholders in connection therewith. In view of the variety of factors
considered in connection with its evaluation of the merger, the E.piphany board
did not find it practicable to, and did not, quantify or otherwise assign
relative weights to the specific factors considered in reaching its
determination. In addition, individual members of the E.piphany board may have
given different weights to different factors. In the course of its
deliberations, the E.piphany board did not establish a range of values for
E.piphany capital stock; however, based on the factors outlined above and after
consultation with its financial advisor, Credit Suisse First Boston, the
E.piphany board unanimously determined that the terms of the merger are fair to,
and that the merger is in the best interest of, E.piphany and its stockholders.

VOTE REQUIRED

     Under the rules of the Nasdaq Stock Market, approval of the issuance of
shares of E.piphany common stock to Octane shareholders in connection with the
merger requires the affirmative vote of holders of a majority of the shares of
E.piphany common stock present or represented at the special meeting of
E.piphany stockholders.

RECOMMENDATION OF E.PIPHANY BOARD OF DIRECTORS

     After careful consideration, the E.piphany board of directors has
unanimously determined that the merger agreement and the transactions
contemplated thereby, including the merger and the issuance of shares of
E.piphany common stock to Octane shareholders, to be fair and in the best
interests of its stockholders and unanimously approved the merger agreement and
the transactions

                                       45
<PAGE>   52

contemplated thereby, including the merger and the proposed issuance of the
shares of E.piphany common stock, and recommend that the E.piphany stockholders
vote for approval of the proposed issuance of shares of E.piphany common stock
to Octane shareholders in connection with the merger.

OPINION OF E.PIPHANY'S FINANCIAL ADVISOR

     Credit Suisse First Boston has acted as E.piphany's exclusive financial
advisor in connection with the merger. E.piphany selected Credit Suisse First
Boston based on Credit Suisse First Boston's experience, expertise and
reputation, and familiarity with E.piphany's business. Credit Suisse First
Boston is an internationally recognized investment banking firm and is regularly
engaged in the valuation of businesses and securities in connection with mergers
and acquisitions, leveraged buyouts, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for corporate and other purposes.

     In connection with Credit Suisse First Boston's engagement, E.piphany
requested that Credit Suisse First Boston evaluate the fairness, from a
financial point of view, to E.piphany of the consideration provided for in the
merger. On March 14, 2000, at a meeting of the E.piphany board of directors held
to evaluate the merger, Credit Suisse First Boston rendered to the E.piphany
board of directors an oral opinion, which opinion was confirmed by delivery of a
written opinion dated March 14, 2000, to the effect that, as of that date and
based on and subject to the matters described in its opinion, the consideration
provided for in the merger was fair, from a financial point of view, to
E.piphany. For purposes of its opinion, Credit Suisse First Boston defined the
consideration as the aggregate number of shares of E.piphany common stock and
options, warrants and other rights to purchase E.piphany common stock to be
issued to Octane shareholders in the merger.

     The full text of Credit Suisse First Boston's written opinion, dated March
14, 2000, to the E.piphany board of directors, which sets forth, among other
things, the procedures followed, assumptions made, matters considered and
limitations on the review undertaken, is attached as Annex V and is incorporated
into this document by reference. Holders of E.piphany common stock are urged to,
and should, read this opinion carefully and in its entirety. Credit Suisse First
Boston's opinion is addressed to the E.piphany board of directors and relates
only to the fairness of the consideration from a financial point of view, does
not address any other aspect of the proposed merger or any related transaction
and does not constitute a recommendation to any E.piphany stockholder or any
Octane shareholder as to any matter relating to the merger. The summary of
Credit Suisse First Boston's opinion in this document is qualified in its
entirety by reference to the full text of the opinion.

     In arriving at its opinion, Credit Suisse First Boston reviewed the merger
agreement and related documents, as well as publicly available business and
financial information relating to E.piphany and available business and financial
information relating to Octane. Credit Suisse First Boston also reviewed other
information relating to E.piphany and Octane, including financial forecasts,
that were provided to or discussed with Credit Suisse First Boston by E.piphany
and Octane. Credit Suisse First Boston also met with the managements of
E.piphany and Octane to discuss the businesses and prospects of E.piphany and
Octane, including the ability to integrate the businesses of E.piphany and
Octane. Credit Suisse First Boston considered financial and stock market data of
E.piphany and financial data of Octane, and compared those data with similar
data for publicly held companies in businesses similar to those of E.piphany and
Octane. Credit Suisse First Boston considered, to the extent publicly available,
the financial terms of other business combinations and other transactions which
have recently been effected. Credit Suisse First Boston also considered other
information, financial studies, analyses and investigations and financial,
economic and market criteria which it deemed relevant.

     In connection with its review, Credit Suisse First Boston did not assume
any responsibility for independent verification of any of the foregoing
information and relied on that information being complete and accurate in all
material respects. Credit Suisse First Boston reviewed and discussed with the
management of E.piphany publicly available financial forecasts relating to
E.piphany and was advised, and assumed, that the forecasts represented
reasonable estimates and judgments as to the future financial performance of
E.piphany. With respect to the financial forecasts for Octane, Credit Suisse
First Boston was advised, and assumed, that the forecasts were reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the managements of E.piphany and Octane as to the future financial
performance of Octane. In addition, Credit Suisse First Boston relied on,
without independent verification, the assessment of the managements of E.piphany
and Octane as to E.piphany's and Octane's ability to retain key employees of
Octane, the strategic benefits anticipated by the managements of E.piphany and
Octane to result from the merger, Octane's existing technology and products and
the validity of, and risks associated with, Octane's future technology and
products and the ability to integrate the businesses of E.piphany and Octane.
Credit Suisse First Boston also assumed, with E.piphany's consent, that the
merger would be treated as a tax-free reorganization for federal income tax
purposes. In addition, Credit Suisse First Boston was not requested to make, and
did not make, an independent evaluation or appraisal of the assets or
liabilities, contingent or otherwise, of E.piphany and Octane, nor was Credit
Suisse First Boston furnished with any evaluations or appraisals.

     Credit Suisse First Boston's opinion is necessarily based on information
available to it, and financial, economic, market and other conditions as they
existed and could be evaluated, on the date of the Credit Suisse First Boston
opinion. Credit Suisse First Boston did not express any opinion as to what the
value of E.piphany common stock actually will be when issued or the prices at
which E.piphany common stock will trade following the merger. Although Credit
Suisse First Boston evaluated the consideration in the merger from a financial
point of view, Credit Suisse First Boston was not requested to, and did not,
recommend the specific consideration payable in the merger, which consideration
was determined through negotiation between E.piphany and Octane. No other
limitations were imposed on Credit Suisse First Boston with respect to the
investigations made or procedures followed in rendering its opinion.

     In preparing its opinion to the E.piphany board of directors, Credit Suisse
First Boston performed a variety of financial and comparative analyses,
including those described below. The summary of Credit Suisse First Boston's
analyses described below is not a complete description of the analyses
underlying Credit Suisse First Boston's opinion. The preparation of a fairness
opinion is a complex process involving various determinations as to the most
appropriate and relevant methods of financial analyses and the application of
those methods to the particular circumstances and, therefore, a fairness opinion
is not readily susceptible to partial analysis or summary description. In
arriving at its opinion, Credit Suisse First Boston made qualitative judgments
as to the significance and relevance of each analysis and factor that it
considered. Accordingly, Credit Suisse First Boston believes that its analyses
must be considered as a whole and that selecting portions of its analyses and
factors or focusing on information presented in tabular format, without
considering all analyses and factors or the narrative description of the
analyses, could create a misleading or incomplete view of the processes
underlying its analyses and opinion.

     In its analyses, Credit Suisse First Boston considered industry
performance, regulatory, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of E.piphany
and Octane. No company, transaction or business used in Credit Suisse First
Boston's analyses as a comparison is identical to E.piphany and Octane or the
proposed merger, and an evaluation of the results of those analyses is not
entirely mathematical. Rather, the analyses involve complex considerations and
judgments concerning financial and operating characteristics and other factors
that could affect the acquisition, public trading or other values of the
companies,

                                       47

business segments or transactions being analyzed. The estimates contained in
Credit Suisse First Boston's analyses and the ranges of valuations resulting
from any particular analysis are not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than those suggested by the analyses. In addition, analyses relating
to the value of businesses or securities do not purport to be appraisals or to
reflect the prices at which businesses or securities actually may be sold.
Accordingly, Credit Suisse First Boston's analyses and estimates are inherently
subject to substantial uncertainty.

     Credit Suisse First Boston's opinion and financial analyses were only one
of many factors considered by the E.piphany board of directors in its evaluation
of the proposed merger and should not be viewed as determinative of the views of
the E.piphany board of directors or management with respect to the merger or the
consideration.

     The following is a summary of the material financial analyses performed by
Credit Suisse First Boston in connection with the preparation of its opinion and
reviewed with the E.piphany board of directors at a meeting of the E.piphany
board of directors held on March 14, 2000. THE FINANCIAL ANALYSES SUMMARIZED
BELOW INCLUDE INFORMATION PRESENTED IN TABULAR FORMAT. IN ORDER TO FULLY
UNDERSTAND CREDIT SUISSE FIRST BOSTON'S FINANCIAL ANALYSES, 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. CONSIDERING THE DATA IN THE
TABLES BELOW WITHOUT CONSIDERING THE FULL NARRATIVE DESCRIPTION OF THE FINANCIAL
ANALYSES, INCLUDING THE METHODOLOGIES AND ASSUMPTIONS UNDERLYING THE ANALYSES,
COULD CREATE A MISLEADING OR INCOMPLETE VIEW OF CREDIT SUISSE FIRST BOSTON'S
FINANCIAL ANALYSES.

     IPO Analysis. Credit Suisse First Boston estimated the present value of
Octane's fully-distributed equity value assuming an initial public offering of
Octane in the third quarter of 2000. Credit Suisse First Boston applied a range
of multiples from 40.0x to 90.0x of estimated calendar year 2001 revenues to the
estimated financial forecasts for Octane as provided by Octane management. This
analysis indicated an implied aggregate reference range for Octane of
approximately $1,260 million to $2,835 million. Credit Suisse First Boston also
applied the multiples of calendar year 2001 revenues observed for two companies
which had recently effected an initial public offering, Selectica, Inc. and
Webmethods, Inc., which resulted in implied aggregate values for Octane of
$5,302 million and $8,959 million. Credit Suisse First Boston noted that the
implied fully-diluted aggregate transaction value of the consideration based on
the closing price for E.piphany common stock as of March 13, 2000 was $3,624
and, based on the average price of E.piphany common stock over the 30 trading
days preceding March 14, 2000 was $2,438 million.

     Transaction Matrix Analysis. Credit Suisse First Boston reviewed the
implied aggregate transaction value of the consideration based on the closing
price for E.piphany as of March 13, 2000 and the average price of E.piphany
common stock over the 30 trading days preceding March 14, 2000 and the implied
multiples of estimated calendar years 2000 and 2001 revenues for Octane. The
revenues of Octane were based upon both the estimates of Octane management,
referred to as the Octane case, and E.piphany management, referred to as the
E.piphany case. This analysis indicated the following implied aggregate
transaction values and multiples of calendar year 2000 and 2001 revenues, as
compared to the multiples for E.piphany on a stand-alone basis and for selected
companies in the e-commerce enabling and e-analytics business categories:

     Contribution Analysis. Credit Suisse First Boston analyzed the relative
contributions of E.piphany and Octane to the revenue of the combined company for
the estimated second half of calendar year 2000 and estimated calendar years
2000 and 2001. E.piphany's revenue estimates were based on securities research
analysts' estimates, and Octane's revenue estimates were based on both the
E.piphany case and the Octane case. Credit Suisse First Boston then analyzed the
pro forma ownership of the combined company implied by Octane's relative
contribution. This analysis indicated the following:

     The above estimates yielded a mean implied Octane stockholder pro forma
ownership of 28.7%. Credit Suisse First Boston noted that the pro forma fully
diluted ownership of the Octane stockholders in the combined company implied by
the merger was 26.3%.

     Pro Forma Impact Analysis. Credit Suisse First Boston analyzed the
potential pro forma effects of the merger on the estimated revenues per share
for E.piphany for the second half of calendar year 2000 and for calendar year
2001. Estimated financial data for E.piphany were based on securities research
analysts' estimates and estimated financial data for Octane were considered
based upon both the E.piphany case and the Octane case. This analysis indicated
the following accretion to E.piphany's estimated revenues per share:

     Pro Forma Trading Analysis. Credit Suisse First Boston reviewed the
potential pro forma effects of the merger on the aggregate value of the combined
company as multiples of estimated calendar years 2000 and 2001 revenues for the
combined company under both the E.piphany case and the Octane case using average
closing stock prices for E.piphany over various periods. Credit Suisse First
Boston compared the results of this analysis with the aggregate value of
E.piphany, the four software companies listed below and the median of the
selected e-commerce enabler companies as

     E.piphany has agreed to pay Credit Suisse First Boston for its financial
advisory services customary fees based on the aggregate value of the merger, a
significant portion of which is contingent upon the consummation of the merger.
Credit Suisse First Boston also received a fee upon delivery of its opinion.
E.piphany also has agreed to reimburse Credit Suisse First Boston for its
out-of-pocket expenses, including fees and expenses of legal counsel and any
other advisor retained by Credit Suisse First Boston, and to indemnify Credit
Suisse First Boston and related parties against liabilities, including
liabilities under the federal securities laws, arising out of its engagement.

     Credit Suisse First Boston and its affiliates have in the past provided and
are currently providing financial services to E.piphany unrelated to the
proposed merger, for which services Credit Suisse First Boston and its
affiliates have received and in the future may receive compensation. In the
ordinary course of business, Credit Suisse First Boston and its affiliates may
actively trade the securities of E.piphany for their own accounts and for the
accounts of customers and, accordingly, may at any time hold long or short
positions in such securities.

OCTANE'S REASONS FOR THE MERGER

     The board of directors of Octane has unanimously approved the merger. In
reaching its determination, the Octane board consulted with Octane's management,
as well as its financial advisor and legal counsel, and gave significant
consideration to a number of factors bearing on its decision.

     The Octane board believes that the proposed merger would afford Octane the
following advantages:

     - the merger would allow the integration of Octane's Internet-based
       customer relationship products, services and technology with the customer
       information collection and analysis products and technology of E.piphany,
       creating a product offering which is broader than Octane's current
       offering. The Board considered Octane's prospects for developing
       products,

                                       51
<PAGE>   58

       services and technology similar to E.piphany's on a stand-alone basis and
       determined that the merger would give the combined enterprise a greater
       competitive advantage and technological lead than Octane could achieve on
       its own,

     - the merger would potentially create increased sales of Octane's products
       and services by exposing Octane to E.piphany's customer base, as well as
       creating additional cross-selling opportunities with Octane's existing
       customers,

     - the merger would allow Octane to more rapidly establish indirect
       distribution channels by leveraging E.piphany's existing relationships,

     - the merger would allow Octane and E.piphany to combine their sales and
       marketing forces, giving Octane greater resources than it could achieve
       on its own for at least twelve months,

     - the merger would give Octane access to E.piphany's substantial capital
       resources to accelerate the development of Octane's products, services
       and technology, and

     - the merger would provide liquidity for Octane's shareholders through
       their ownership of E.piphany common stock.

     In the course of its deliberations, the Octane board also considered a
number of additional factors relevant to the merger. These factors included:

     - information concerning the respective businesses, prospects, historical
       financial results and condition, operations, management and future
       development plans of Octane and E.piphany,

     - the limited trading history and volume of E.piphany common stock,

     - the market value of the E.piphany common stock to be issued or issuable
       in respect of Octane capital stock, including options and warrants to
       purchase Octane capital stock,

     - the terms of the merger agreement and the transactions contemplated by
       the merger agreement,

     - the compatibility of the respective management teams and employees of
       Octane and E.piphany,

     - levels of interest in and potential valuations of Octane offered by other
       potential investors or acquirors,

     - the results of financial and operational due diligence on E.piphany,

     - the expectation that the merger will qualify as a tax-free
       reorganization, and

     - the fact that the merger will be accounted for as a purchase.

     The Octane board also considered a variety of potential negative factors
relating to the proposed merger, including:

     - the volatility of E.piphany's stock price and the volatility of the
       prices for technology companies generally,

     - the potential disruption of existing and prospective relationships with
       Octane's customers that could result from the announcement or
       consummation of the merger,

     - the potential disruption of Octane's management team and employees that
       could result from the announcement or consummation of the merger,

     - the risk that the anticipated benefits of the merger might not be
       realized,

                                       52
<PAGE>   59

     - the risk that Octane shareholders might incur liability for claims of
       indemnification by E.piphany after the merger, and

     - the risks described above in the section entitled "Risk Factors."

     The Octane board also considered the possibility of pursuing an initial
public offering, or IPO, of Octane's common stock as an alternative to the
merger. The board considered, among other things:

     - the value that Octane's stockholders could be expected to realize after
       an IPO, 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 Octane's common stock, and

     - the anticipated restrictions on liquidity for Octane's existing
       shareholders after an IPO relative to those after the merger.

     Considering each of the above factors and the relative risks and merits of
an IPO and the merger, the Octane board concluded that, on balance, the merger
was likely to be more favorable to Octane's shareholders than a possible future
IPO.

     The preceding discussion of the information and factors considered by the
Octane board is not, and is not intended to be, exhaustive, but is believed to
include the material factors considered by the Octane board in evaluating the
merger. In view of the variety of factors considered in connection with its
evaluation of the merger, the Octane board did not find it practicable to, and
did not, quantify or otherwise assign relative weights to the specific factors
considered in reaching its determination. In addition, individual members of the
Octane board may have given different weights to different factors. Based on the
factors outlined above and after consultation with its financial adviser, Morgan
Stanley Dean Witter, the Octane board unanimously determined that the terms of
the merger are fair to, and that the merger is in the best interest of, Octane
and its shareholders.

VOTE REQUIRED

     Under applicable California law and the charter documents of Octane,
approval of the merger and the merger agreement requires the affirmative vote of
holders of:

     - a majority of the outstanding shares of Octane common stock,

     - a majority of the outstanding shares of Octane preferred stock, and

     - a majority of all outstanding shares of Octane common stock and preferred
       stock, voting together on an as-converted basis.

RECOMMENDATION OF OCTANE'S BOARD OF DIRECTORS

     After careful consideration of the foregoing factors, the Octane board of
directors has unanimously determined that the merger agreement and the
transactions contemplated thereby, including the merger and the automatic
conversion of Octane preferred stock into Octane common stock to be fair and in
the best interests of its shareholders and unanimously approved the merger
agreement and the transactions contemplated thereby, including the merger and
the automatic conversion of Octane preferred stock into Octane common stock and
recommend that the Octane shareholders vote to approve and adopt the merger
agreement, the merger and the automatic conversion of the Octane preferred stock
into Octane common stock.

INTERESTS OF CERTAIN OFFICERS, DIRECTORS AND AFFILIATES OF OCTANE IN THE MERGER

     In considering the recommendation of the Octane board with respect to the
merger agreement and the transactions contemplated thereby, including the merger
and the automatic conversion of

                                       53

Octane preferred stock, shareholders of Octane should be aware that certain
members of the Octane board and management have certain interests in the merger
that are in addition to the interests of Octane's shareholders generally. These
interests are as follows:

     - In accordance with the merger agreement, Aditya (Tim) Guleri, William
       Walsh, Kira Makagon, James Doehrman, Robert Loughan, Robert Gryphon and
       Manu Kumar have entered into employment and noncompetition agreements

       and target incentive in the same amount as such executive had previously
       agreed with Octane, subject to annual review and adjustment.

     - E.piphany currently anticipates that most employees of Octane, including
       all of its officers, will be employed by E.piphany after the merger.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion summarizes the material federal income tax
consequences of the exchange of shares of Octane capital stock for E.piphany
common stock pursuant to the merger. This discussion is based on currently
existing provisions of the Internal Revenue Code, referred to herein as the
Code, existing Treasury Regulations thereunder and current administrative
rulings and court decisions, all of which are subject to change. Any such
change, which may or may not be retroactive, could alter the U.S. federal income
tax consequences to E.piphany, Octane or the Octane shareholders.

     Octane shareholders should be aware that this discussion does not address
all U.S. federal income tax considerations that may be relevant to particular
shareholders of Octane in light of their particular circumstances, such as
shareholders who are banks, insurance companies, tax-exempt organizations,
dealers in securities, foreign persons, shareholders who do not hold their
Octane stock as capital assets, shareholders who acquired their shares in
connection with stock option or stock purchase plans or in other compensatory
transactions, shareholders who hold Octane capital stock as part of an
integrated investment (including a "straddle") comprised of shares of Octane
capital stock and one or more other positions, or shareholders who have
previously entered into a constructive sale of Octane capital stock. In
addition, the following discussion does not address the tax consequences of the
merger under foreign, state or local tax laws.

     It is a condition to the obligation of each of E.piphany and Octane to
complete the merger that E.piphany receive an opinion of Wilson Sonsini Goodrich
& Rosati, Professional Corporation, and Octane receive an opinion of Venture Law
Group, A Professional Corporation, to the effect that the merger will be treated
for federal income tax purposes as a reorganization within the meaning of
Section 368(a) of the Code. However, if either tax counsel does not render an
opinion, such condition nonetheless will be satisfied if tax counsel to the
other party renders an opinion to such other party. Tax counsel's opinions
neither bind the Internal Revenue Service, referred to herein as the IRS, nor
preclude the IRS or the courts from adopting a contrary position. Neither
E.piphany nor Octane intends to obtain a ruling from the IRS on the tax
consequences of the merger.

     In delivering their opinions, tax counsel will rely on certain customary
representations made by E.piphany and Octane, including those contained in
certificates of officers of E.piphany and Octane. Provided that such
representations are correct as of the effective time of the merger, that the
merger is consummated in the manner described in the merger agreement and this
proxy statement/ prospectus and that there are no changes in the Code or other
applicable law, the merger will be a

                                       55
<PAGE>   62

reorganization within the meaning of Section 368(a) of the Code. Assuming that
the merger is a reorganization, the merger will have the following federal
income tax consequences:

     - No gain or loss will be recognized by holders of Octane stock upon their
       receipt of E.piphany common stock solely in exchange for Octane stock in
       the merger.

     - The aggregate tax basis of the E.piphany common stock received by Octane
       shareholders in the merger (including the escrow shares) will be the same
       as the aggregate tax basis of Octane stock surrendered in exchange
       therefor.

     - The holding period of the E.piphany common stock (including the escrow
       shares) received in the merger will include the period for which the
       Octane stock surrendered in exchange therefor was held.

     - A shareholder who exercises dissenters' rights with respect to a share of
       Octane stock and who receives payment for such stock in cash will
       generally recognize capital gain or loss measured by the difference
       between the shareholder's tax basis in such share and the amount of cash
       received, provided that such payment is neither essentially equivalent to
       a dividend nor has the effect of a distribution of a dividend. Generally,
       a disposition of Octane stock pursuant to an exercise of dissenters'
       rights will not be essentially equivalent to a dividend and will not have
       the effect of the distribution of a dividend if the shareholder
       exercising such rights will no longer own any shares of E.piphany or
       Octane stock after such exercise (either actually or constructively
       pursuant to certain attribution rules in Section 318 of the Code).

       Any Octane shareholder who exercises dissenters' rights may be subject to
       backup withholding at a rate of 31% on cash payments received. Backup
       withholding will not apply, however, if the shareholder exercising
       dissenters' rights is an exempt recipient (such as a corporation or
       financial institution) or is otherwise exempt from backup withholding, if
       the shareholder furnishes a correct taxpayer identification number and
       certifies that he, she or it is not subject to backup withholding on the
       substitute Form W-9 included in the letter of transmittal, or if the
       shareholder provides a certificate of foreign status on Form W-8.

     - E.piphany, Orchid Acquisition Corporation and Octane will not recognize
       any gain solely as a result of the merger.

     A failure of the merger to qualify as a reorganization would result in
Octane shareholders recognizing taxable capital gain or loss with respect to
each share of Octane stock surrendered equal to the difference between the
shareholder's tax basis in such share and the fair market value, as of the
closing of the merger, of the E.piphany common stock received in exchange
therefor. In such event, a shareholder's aggregate basis in the E.piphany common
stock so received would equal its fair market value as of the closing of the
merger and the holding period for such stock would begin the day after the
closing of the merger.

     This discussion of material federal income tax consequences is intended to
provide only a general summary, and is not a complete analysis or description of
all potential federal income tax consequences of the merger. This discussion
does not address tax consequences that may vary with, or are contingent on,
individual circumstances. In addition, it does not address any non-income tax or
any foreign, state or local tax consequences of the merger. Accordingly, Octane
shareholders are urged to consult their own tax advisors as to the specific tax
consequences of the merger, including the applicable federal, state, local and
foreign tax consequences to them of the merger in their particular
circumstances.

ACCOUNTING TREATMENT

     The merger will be accounted for under the "purchase" method of accounting
in accordance with generally accepted accounting principles.

LISTING ON THE NASDAQ STOCK MARKET'S NATIONAL MARKET

     The shares of E.piphany common stock to be issued in the merger will be

REGULATORY APPROVALS

     As required under federal antitrust law, E.piphany and Octane notified the
Department of Justice and Federal Trade Commission of the proposed merger. If
neither of these agencies request additional information concerning the merger,
or object to the merger, within thirty days of the filing, then E.piphany and
Octane may proceed with the merger.

or about May 31, 2000.

MERGER CONSIDERATION

     A total of approximately 12.8 million shares of E.piphany common stock,
less an amount of shares of E.piphany common stock equal to the amount by which
estimated third party expenses exceed $1,500,000 divided by $192.85 (as
appropriately adjusted for stock splits, dividends, combinations and the like),
will be issued or issuable in the merger to Octane shareholders, optionholders
and warrantholders, subject to the escrow provisions described below.

DIRECTORS AND OFFICERS OF OCTANE AFTER THE MERGER

     The current directors and officers of Octane will not be directors and
officers of Octane after the merger. Upon consummation of the merger, the
directors of Octane will be:

     - Roger S. Siboni, the President and Chief Executive Officer of E.piphany,

     - Kevin J. Yeaman, the Chief Financial Officer of E.piphany, and

     - Deborah E. Townsend, the Director, Legal Affairs of E.piphany.

     In addition, the officers of Octane will be:

     - Roger S. Siboni, as President,

     - Kevin J. Yeaman, as Treasurer, and

     - Deborah E. Townsend, as Secretary.

ARTICLES OF INCORPORATION AND BYLAWS OF OCTANE AFTER THE MERGER

     The current articles of incorporation and bylaws of Orchid Acquisition
Corporation will become the articles of incorporation and bylaws of Octane upon
the merger.

CONVERSION OF OCTANE CAPITAL STOCK AS A RESULT OF THE MERGER

     As a condition to the closing of the merger, all outstanding shares of
Octane preferred stock must be converted into shares of Octane common stock. For
a more detailed explanation of the

                                       58
<PAGE>   65

conversion of Octane shares, see "Conversion of Octane Preferred Stock." As
specified in the merger agreement, each share of Octane common stock issued and
outstanding immediately prior to the merger -- excluding shares held by a holder
who has demanded and perfected dissenters' rights for his or her shares in
accordance with the applicable provisions of California law and has not
withdrawn or lost his or her rights -- will be cancelled and extinguished and be
converted automatically into the right to receive a number of shares of
E.piphany common stock equal to the exchange ratio calculated in accordance with
the merger agreement. No fractional shares of E.piphany common stock will be
issued in the merger. Instead, any fractional share will be rounded down to the
nearest whole share of E.piphany common stock. The number of shares of E.piphany
common stock to be received by Octane shareholders is an approximation based on
information available at this time. The actual numbers may differ based on the
actual number of shares of Octane common stock and options and warrants for
Octane common stock outstanding at the time of the merger.

CALCULATION OF EXCHANGE RATIO

     Upon the completion of the merger, E.piphany will acquire all outstanding
shares of Octane stock. Octane shareholders will receive approximately 0.5179 of
a share of E.piphany common stock for each share of Octane stock held by Octane
shareholders. Of this number, approximately 0.0564 of a share of E.piphany
common stock will be placed into an escrow fund. In addition, E.piphany will
assume each outstanding option, warrant and other rights to purchase Octane
stock. The exchange ratio represents the fraction of a share of E.piphany common
stock to be issued for each share of Octane stock in the merger, and is
calculated as follows:

     - the quotient of 12,793,510 shares of E.piphany common stock minus the
       number of shares of E.piphany common stock equivalent to the dollar
       amount by which estimated third party expenses, excluding investment
       banking advisory fees, exceed $1,500,000, and

     - the aggregate number of shares of Octane common stock, including all
       shares underlying convertible securities, options and warrants to
       purchase Octane common stock, outstanding immediately prior to the
       effective time of the merger.

     As of March 31, 2000, there were no estimated third party expenses,
excluding investment banking advisory fees, exceeding $1,500,000 and the
aggregate amount of outstanding shares of Octane common stock plus aggregate
shares issuable upon exercise or conversion of all outstanding convertible
securities, options and warrants equaled 24,700,281 shares. Thus, a holder of
one share of Octane stock would receive approximately 0.5179, less the
approximately 0.0564 of a share to be placed into the escrow fund, of one share
of E.piphany common stock for each share of Octane stock.

     Assuming the same exchange ratio and based on the capitalization of
E.piphany and Octane as of March 31, 2000, the approximately 11,755,138 shares
of E.piphany common stock expected to be issued in the merger, excluding the
1,038,372 shares of E.piphany common stock subject to stock options held by
Octane optionholders -- and assumed by E.piphany in the merger -- would
represent approximately 26.6% of the shares of E.piphany common stock
outstanding and subject to options immediately following the merger.

Octane Stock Options and Warrants

     In the merger, all outstanding options and warrants to purchase shares of
Octane common stock at the effective time of the merger will be assumed by
E.piphany and remain outstanding. However, each Octane option will be
exercisable for E.piphany common stock. The number of shares of E.piphany common
stock issuable upon exercise of an Octane option or warrant and the exercise
price of Octane options and warrants will be adjusted to reflect the exchange
ratio discussed above.

                                       59
<PAGE>   66

E.piphany Stock Split and Similar Matters.

     The number of shares of E.piphany common stock issuable in the merger, and
the resulting exchange ratio, are subject to adjustment in the event that
E.piphany effects a stock split, stock dividend, cash dividend, distribution,
reorganization or recapitalization prior to the merger.

PROCEDURE FOR EXCHANGING OCTANE COMMON STOCK FOR E.PIPHANY COMMON STOCK

     The merger agreement requires E.piphany, as soon as practicable after the
merger, to deposit with Equiserve, E.piphany's exchange agent, or such other
institution as it may select, for the benefit of the holders of shares of Octane
capital stock, certificates representing the shares of E.piphany common stock to
be issued in the merger.

Exchange Procedures

     E.piphany has included with this proxy statement/prospectus a letter of
transmittal for each Octane shareholder to utilize to exchange Octane stock
certificates for E.piphany stock certificates after the merger is consummated.
After the merger is completed, E.piphany will send each Octane shareholder
written notice advising the shareholder to send in his or her Octane stock
certificates to be exchanged for E.piphany stock certificates. Once an Octane
shareholder has delivered his or her Octane stock certificate to E.piphany's
exchange agent, together with an executed letter of transmittal and such other
documents as may reasonably be required by the exchange agent, the Octane
shareholder will receive his or her E.piphany stock certificates, less the
portion placed in the escrow fund. See "-- Escrow Fund and Indemnification."

Octane shareholders should not forward Octane stock certificates to the exchange
agent until they have received written notice from E.piphany to so do. Octane
shareholders should not return Octane stock certificates with their proxy or
consent.

     Octane shareholders should also note:

     No dividends or other distributions on E.piphany common stock declared or
made after the merger will be paid to any holder of any unsurrendered Octane
stock certificate with respect to the shares of E.piphany common stock
represented by the unsurrendered certificate until the certificate is
surrendered to the Exchange Agent.

     If any certificate for shares of E.piphany common stock is to be issued in
a name other than that in which the Octane stock certificate surrendered in
exchange therefor is registered, the Octane stock certificate so surrendered
must be properly endorsed and otherwise in proper form for transfer and the
person requesting the exchange will have to pay E.piphany or any agent
designated by E.piphany any transfer or other taxes required by reason of
issuance of a certificate for shares of E.piphany common stock in any name other
than that of the registered holder of the Octane stock certificate surrendered,
or establish to the satisfaction of E.piphany or any agent designated by
E.piphany that the tax has been paid or is not payable.

     In the event that any Octane stock certificates representing shares of
Octane capital stock have been lost, stolen or destroyed, the exchange agent
will issue shares of E.piphany common stock in exchange for the lost, stolen, or
destroyed Octane stock certificates upon the making of an affidavit of that fact
by the owner of the Octane stock certificates and, at the request of E.piphany,
upon delivery of a bond in an amount as E.piphany may reasonably direct as
indemnity against any claim that may be made against E.piphany or the exchange
agent with respect to the Octane stock certificates alleged to have been lost,
stolen or destroyed.

FORM S-8 FILING

     E.piphany has agreed to file with the Securities and Exchange Commission,
within 15 days after the closing of the merger, a registration statement on Form
S-8 to register shares of E.piphany common stock issuable as a result of the
exercise of Octane options assumed in the merger.

     By Octane and E.piphany, if they mutually agree,

     By E.piphany or Octane if:

     - the merger has not occurred by October 15, 2000, unless the party seeking
       to terminate the merger agreement had acted or failed to act in such a
       manner as to be the principal cause of or resulted in the failure of the

       constitutes a breach of the merger agreement,

     - there is a final nonappealable order of a federal or state court in
       effect preventing the merger, or

     - there is any statute, rule, regulation or order enacted, promulgated or
       issued or deemed applicable to the merger by any governmental entity that
       would make consummation of the merger illegal.

     By E.piphany if:

     - any governmental entity has prohibited E.piphany's or Orchid Acquisition
       Corporation's ownership or operation of any portion of the business of
       Octane, or required E.piphany or Octane to dispose of or hold separate
       all or a portion of the business or assets of Octane or E.piphany as a
       result of the merger,

     - E.piphany is not in material breach of its obligations under the merger
       agreement and there has been a material breach of any representation,
       warranty, covenant or agreement contained in the merger agreement on the
       part of Octane and the breach has not been cured within ten days after
       written notice to Octane, but no cure period is required for a breach

<PAGE>   72

ESCROW FUND AND INDEMNIFICATION

     An aggregate of 10% of the total number of shares of E.piphany common stock
that constitute the merger consideration under the merger agreement will
automatically be contributed to the escrow fund. The escrow fund will be the
exclusive remedy available to compensate E.piphany and its officers, directors
and affiliates -- referred to in the paragraphs to follow as the indemnified
parties -- for:

     - any losses incurred by E.piphany or for which E.piphany would otherwise
       be liable as a result of any inaccuracy or breach of a representation or
       warranty of Octane contained in the merger agreement or any related
       agreement, and

     - any failure by Octane to perform or comply with any covenant in the
       merger agreement or any related agreement.

     For purposes of compensating E.piphany for its losses, the escrow shares
will be valued at $192.85 per share. The escrow fund shall not be available to
compensate the indemnified parties for any losses until the aggregate losses for
which indemnification is sought exceeds $1,750,000, in which case the full
amount of the loss, including the $1,750,000, will be subject to
indemnification. However, if aggregate losses attributable to breaches of
representations and warranties relating to intellectual property exceed $500,000
before such time as the total aggregate losses exceed $1,750,000, then Octane
will have liability to the indemnified parties to the extent of the losses
attributable to breaches of representations and warranties relating to
intellectual property, including the $500,000. In addition, if Octane has
liability to the indemnified parties for losses attributable to breaches of
representations and warranties relating to intellectual property over and
including the $500,000, then the $1,750,000 limitation will be reduced to
$1,250,000 for losses other than losses relating to intellectual property.

     Octane shareholders will have voting rights with respect to the escrow
shares while in escrow, and will receive dividends, if any, attributable to the
escrow shares.

     Subject to any unresolved claims, the escrow fund and the indemnity will
terminate on the one year anniversary of the closing date of the merger, and the
remaining escrow shares will be distributed to the former shareholders of
Octane. The escrow shares and the indemnity will be the exclusive remedy of the
indemnified parties to recover for any losses they suffer by reason of the
breach of any representation, warranty or covenant of Octane. However, the
indemnified party's remedy will not be so limited in the case of fraud or
willful misconduct by Octane.

SECURITYHOLDER AGENT

     BY APPROVING THE MERGER AGREEMENT, OCTANE SHAREHOLDERS WILL HAVE CONSENTED
TO THE APPOINTMENT OF DAVID STROHM, A MEMBER OF THE BOARD OF DIRECTORS OF
OCTANE, TO ACT AS THE SECURITYHOLDER AGENT ON BEHALF OF OCTANE SHAREHOLDERS, TO

RESPECT TO SUCH CLAIMS, AND TO TAKE CERTAIN OTHER ACTION ON BEHALF OF OCTANE

obligation of the respective party incurring the fees and expenses.

OTHER COVENANTS

     The merger agreement also contains various other covenants and agreements
that are customary in transactions of this nature, including:

     - E.piphany and Octane have agreed to prepare and cause to be filed with
       the Securities and Exchange Commission a registration statement on Form
       S-4 including this proxy statement/prospectus for (a) the solicitation of
       approval of the shareholders of Octane of the merger agreement, the
       merger and the conversion of the shares of Octane preferred stock, and
       (b) the solicitation and approval of the stockholders of E.piphany of the
       issuance of shares of E.piphany common stock to Octane shareholders in
       connection with the merger, and (c) to register the sale of the shares of
       E.piphany common stock issuable in the merger.

     - E.piphany and Octane have agreed to respond promptly to any comments of
       the staff of the Securities and Exchange Commission and to use their
       respective reasonable best efforts to have the registration statement on

       resource policy, and will be given credit for service with Octane prior
       to the merger.

any customer of E.piphany or its subsidiaries.

AFFILIATE AGREEMENTS

     All directors, executive officers and affiliates of Octane and their
respective affiliates have entered into agreements with E.piphany. The
agreements provide, among other things, that Octane affiliates will not sell,
transfer or otherwise dispose of the shares of E.piphany common stock issued to
such affiliate in the merger other than in compliance with Rule 145 promulgated
under the Securities Act of 1933 unless the affiliate delivers to E.piphany a
written opinion from counsel, reasonably acceptable to E.piphany, that the sale,
transfer or disposition is otherwise exempt from registration under the

will place legends on the stock certificates and place stop transfer orders with
its transfer agent to ensure compliance with Rule 145.

VOTING AGREEMENTS

     Octane Voting Agreements. As a condition to E.piphany entering into the
merger agreement, the executive officers, directors, venture capital firms
affiliated with the directors, and other affiliates of Octane entered into
voting agreements with E.piphany. By entering into the voting agreements, these
Octane shareholders have agreed to vote their shares of Octane stock in favor of
the merger agreement, the merger and the preferred stock conversion and to
irrevocably appoint E.piphany as their lawful attorney and proxy. These proxies
give E.piphany the limited right to vote the shares of Octane capital stock
beneficially owned by these Octane shareholders, including shares of Octane
capital stock acquired after the date of the voting agreement, in favor of the
approval and adoption of the merger agreement and the merger and, in the case of
holders of Octane preferred stock, to vote in favor of the automatic conversion
of Octane preferred stock into Octane common stock immediately prior to the
merger and in favor of each other matter that could reasonably be expected to
facilitate the merger. These Octane shareholders may vote their shares of Octane
capital stock on all other matters.

     As of April 14, 2000, these Octane shareholders collectively beneficially
owned:

     - 74.7% of the outstanding shares of common stock,

     - 74.3% of the outstanding shares of preferred stock, and

     - 74.5% of the outstanding shares of common stock and preferred stock
       voting as a class.

     None of the Octane shareholders who are parties to the voting agreement
were paid additional consideration in connection with entering into a voting
agreement.

                                       68
<PAGE>   75

     Pursuant to the voting agreements, and except as otherwise waived by
E.piphany, each Octane shareholder who is party to a voting agreement agreed not
to sell the Octane stock and options owned, controlled or acquired, either
directly or indirectly, by that person until the earlier of the termination of
the merger agreement or the completion of the merger, unless the transfer is in
accordance with any affiliate agreement between the Octane shareholder and
E.piphany and each person to which any shares or any interest in any shares is
transferred agrees to be bound by the terms and provisions of their voting
agreement.

THE OCTANE VOTING AGREEMENTS WILL TERMINATE UPON THE EARLIER TO OCCUR OF THE
TERMINATION OF THE MERGER AGREEMENT AND THE COMPLETION OF THE MERGER. THE FORM
OF VOTING AGREEMENT IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS ANNEX II
AND YOU ARE URGED TO READ IT IN ITS ENTIRETY.

connection with the merger, and in favor of each other matter that could
reasonably be expected to facilitate the merger. These E.piphany stockholders
may vote their shares of Octane capital stock on all other matters.

     As of April 14, 2000, these E.piphany stockholders collectively
beneficially owned 31.1% of the outstanding shares of common stock.

THE E.PIPHANY VOTING AGREEMENTS WILL TERMINATE UPON THE EARLIER TO OCCUR OF THE
TERMINATION OF THE MERGER AGREEMENT AND THE COMPLETION OF THE MERGER. THE FORM
OF VOTING AGREEMENT IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS ANNEX III,
AND YOU ARE URGED TO READ IT IN ITS ENTIRETY.

                      CONVERSION OF OCTANE PREFERRED STOCK

     In connection with the proposed merger, Octane's board of directors is
requesting the approval of holders of its preferred stock of a proposal to
automatically convert all Octane preferred stock into Octane common stock
effective immediately prior to the merger. The Octane board adopted this
proposal at its meeting on March 14, 2000 subject to approval by the holders of
Octane preferred stock.

THE PROPOSAL

     Octane's amended and restated articles of incorporation provide that Octane
preferred stock is convertible into Octane common stock at any time at the
election of the holder, and that all Octane preferred stock will automatically
convert into Octane common stock upon the affirmative vote of at least 66 2/3%
of the Octane preferred stock, voting as a single class. Each share of Octane
preferred stock is presently convertible into one share of Octane common stock.

     Upon conversion into common stock, holders of preferred stock will no
longer be entitled to preferential dividend, liquidation, antidilution or voting
rights presently enjoyed by the various series of Octane preferred stock. There
are no declared but unpaid dividends with respect to any shares of Octane
preferred stock.

OCTANE'S REASONS FOR THE PREFERRED STOCK CONVERSION

     Under the terms of Octane's preferred stock, the proposed merger would be
deemed a "liquidation" of Octane, thereby triggering the liquidation preferences
and distribution of consideration as set forth in Octane's amended and restated
articles of incorporation. Based on the value of the consideration to be paid by
E.piphany in the merger at the time the merger agreement was signed

                                       69
<PAGE>   76

and the number of shares of Octane capital stock outstanding or subject to
outstanding options or warrants, holders of Octane common stock and preferred
stock would receive the same aggregate consideration per share on a common stock
equivalent basis, even in such a "liquidation."

     The per share consideration to be paid for Octane capital stock in the
merger was determined based on the average trading price of E.piphany's common
stock for a thirty-day period ending the day before the merger agreement was
signed. By contrast, the liquidation preference provisions of Octane's amended
and restated articles of incorporation determine the distribution of merger
consideration based on the average price of the acquiror's common stock for a
thirty-day period expiring three days before the acquisition closes.

     As a result of this disparity, a reduction in the price of E.piphany's
common stock in the period between signing and closing could result in the
holders of Octane common stock receiving substantially less per share than
holders of Octane preferred stock in the merger. The Octane board, which is
comprised predominantly of members designated by holders of Octane preferred
stock, determined that such an outcome would not be an equitable distribution of
the proceeds of the merger. The conversion of all preferred stock into common
stock immediately prior to the merger prevents disparate treatment of holders of
Octane preferred and common stock.

REQUIRED VOTE AND BOARD RECOMMENDATION

     Octane's board of directors unanimously recommends that all holders of
Octane preferred stock vote FOR this proposal. Approval of this proposal
requires the affirmative vote of holders of preferred stock representing at
least 66 2/3% of the votes attributable to Octane preferred stock. Abstentions
will thus have the effect of a vote against the proposal.

     All of Octane's executive officers, directors, venture capital firms
affiliated with some of the directors, and other affiliates have agreed to vote
all of their shares of Octane preferred stock in favor of the preferred stock
conversion.

                          COMPARISON OF CAPITAL STOCK

DESCRIPTION OF E.PIPHANY CAPITAL STOCK

     E.piphany is authorized to issue 100,000,000 shares of common stock,
$0.0001 par value, and 5,000,000 shares of undesignated preferred stock, $0.0001
par value. The following description of E.piphany's capital stock is subject to
and qualified in its entirety by E.piphany's amended certificate of
incorporation and bylaws, and by the provisions of applicable Delaware law.

E.PIPHANY COMMON STOCK

     As of April 14, 2000, there were 32,444,364 shares of common stock
outstanding which were held of record by approximately 334 stockholders. This
does not include the number of persons whose stock is in nominee or "street
name" accounts through brokers. As of the date hereof there are no shares of
preferred stock outstanding.

     The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the board of directors out of funds legally available for that
purpose. For a more detailed explanation, see "Payment of Dividends and
Repurchase of Shares." In the event of the liquidation, dissolution or winding
up of E.piphany, the holders of common stock are entitled to share ratably in
all assets remaining after payment of liabilities, subject to prior distribution
rights of preferred stock, if any, then outstanding. The holders of common stock
have no preemptive or conversion rights or other subscription rights. There are
no redemption or sinking fund provisions applicable to the common stock.

E.PIPHANY PREFERRED STOCK

     E.piphany's board of directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, which may be
greater than the rights of the common stock. It is not possible to state the
actual effect of the issuance of any shares of preferred stock upon the rights
of holders of the common stock until E.piphany's board of directors determines
the specific rights of the holders of such preferred stock. However, the effects
might include, among other things:

     - restricting dividends on the common stock,

     - diluting the voting power of the common stock,

     - impairing the liquidation rights of the common stock, or

     - delaying or preventing a change in control of E.piphany without further
       action by the stockholders.

No shares of preferred stock are outstanding and we have no present plans to
issue any shares of preferred stock.

E.PIPHANY WARRANTS

     As of April 14, 2000, there were warrants outstanding to purchase up to
70,745 shares of common stock of E.piphany.

                                       71
<PAGE>   78

E.PIPHANY REGISTRATION RIGHTS

     As of April 14, 2000, the holders of 17,289,188 shares of common stock were
entitled to the following rights with respect to registration of such shares
with the Securities and Exchange Commission.

     These rights are provided under the terms of an agreement between E.piphany
and the holders of registrable securities. If holders of at least 50% of the
outstanding registrable securities request that at least 30% of the outstanding
registrable securities be registered, E.piphany may be required, on up to two
occasions, to register their shares for public resale. E.piphany is obligated to
register these shares only if the outstanding registrable securities have an
anticipated public offering price of at least $6,000,000. Also, holders of
registrable securities may require on two separate occasions within any twelve
month period that E.piphany registers their shares for public resale on Form S-3
or similar short-form registration, if available, if the value of the securities
to be registered is at least $2,000,000. Depending on market conditions,
however, E.piphany may defer such registration for up to 120 days. Furthermore,
in the event E.piphany elects to register any E.piphany shares of common stock
for purposes of effecting any public offering, the holders of the registrable
securities described above are entitled to include their shares of common stock
in the registration, but E.piphany may reduce the number of shares proposed to
be registered in view of market conditions. All expenses in connection with any
registration, other than underwriting discounts and commissions, will be borne
by E.piphany. All registration rights will terminate on September 21, 2004, or,
with respect to each holder of registrable securities, at such time as the
holder is entitled to sell all of its shares in any three month period under
Rule 144 promulgated under the Securities Act of 1933.

LIMITATION OF LIABILITY OF DIRECTORS OF E.PIPHANY

     The Delaware General Corporation Law permits a corporation to include a
provision in its certificate of incorporation eliminating or limiting the
personal liability of a director or officer to the corporation or its
stockholders for damages for a breach of the director's fiduciary duty, subject
to certain limitations. E.piphany's certificate of incorporation includes such a
provision to the maximum extent permitted by law.

     While these provisions provide directors with protection from awards for
monetary damages for breaches of their duty of care, they do not eliminate that
duty. Accordingly, these provisions will have no effect on the availability of
equitable remedies such as an injunction or rescission based on a director's
breach of his or her duty of care.

INDEMNIFICATION OF DIRECTORS AND OFFICERS OF E.PIPHANY

     The Delaware General Corporation Law permits a corporation to indemnify
officers and directors for actions taken in good faith and in a manner they
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and with respect to any criminal action, which they had no
reasonable cause to believe was unlawful.

     E.piphany's certificate of incorporation and bylaws provide that any person
who was or is a party or is threatened to be a party to or is involved in any
action, suit, or proceeding, whether civil, criminal, administrative or
investigative, because that person is or was a director or officer, or is or was
serving at the request of E.piphany as a director, officer, employee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, will be indemnified against expenses, including attorney's fees, and
held harmless by E.piphany to the fullest extent permitted by the Delaware
General Corporation Law. The indemnification rights conferred by E.piphany are
not exclusive of any other right to which persons seeking indemnification may be
entitled under any statute, E.piphany's certificate of incorporation or bylaws,
any agreement, vote of stockholders or

                                       72
<PAGE>   79

disinterested directors or otherwise. In addition, E.piphany is authorized to
purchase and maintain insurance on behalf of its directors and officers.

     Additionally, E.piphany may pay expenses incurred by its directors or
officers in defending a civil or criminal action, suit or proceeding because
that person is a director or officer, in advance of the final disposition of
that action, suit or proceeding. However, such payment will be made only if
E.piphany receives an undertaking by or on behalf of that director or officer to
repay all amounts advanced if it is ultimately determined that he or she is not
entitled to be indemnified by E.piphany.

ANTI-TAKEOVER EFFECTS OF E.PIPHANY'S CERTIFICATE AND BYLAWS AND DELAWARE LAW

     Some provisions of Delaware law and E.piphany's certificate of
incorporation and bylaws could make the following more difficult:

     - acquisition of E.piphany by means of a tender offer,

     - acquisition of E.piphany by means of a proxy contest or otherwise, or

     - removal of E.piphany's incumbent officers and directors.

These provisions, summarized below, are expected to discourage coercive takeover
practices and inadequate takeover bids. These provisions are also designed to
encourage persons seeking to acquire control of E.piphany to first negotiate
with E.piphany's board of directors. E.piphany believes that the benefits of
increased protection of its potential ability to negotiate with the proponent of
an unfriendly or unsolicited proposal to acquire or restructure E.piphany
outweighs the disadvantages of discouraging such proposals because negotiation
of such proposals could result in an improvement of their terms.

     Election and Removal of Directors. E.piphany's board of directors is
divided into three classes. The directors in each class will serve for a
three-year term, one class being elected each year by the stockholders. For more
information on the classified board, see the sections entitled "Classification
of Board of Directors" and "Management -- Classified Board." This system of
electing and removing directors may tend to discourage a third party from making
a tender offer or otherwise attempting to obtain control of E.piphany because it
generally makes it more difficult for stockholders to replace a majority of the
directors.

     Stockholder Meetings. Under E.piphany's bylaws, only the board of
directors, the chairman of the board and the president may call special meetings
of stockholders.

     Requirements for Advance Notification of Stockholder Nominations and
Proposals. E.piphany's bylaws establish advance notice procedures with respect
to stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board of directors.

     Delaware Anti-Takeover Law. E.piphany is subject to Section 203 of the
Delaware General Corporation Law, an anti-takeover law. In general, Section 203
prohibits a publicly held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years
following the date the person became an interested stockholder, unless the
"business combination" or the transaction in which the person became an
interested stockholder is approved in a prescribed manner. Generally, a
"business combination" includes a merger, asset or stock sale, or other
transaction resulting in a financial benefit to the interested stockholder.
Generally, an "interested stockholder" is a person who, together with affiliates
and associates, owns or within three years prior to the determination of
interested stockholder status, did own, 15% or more of a corporation's voting
stock. The existence of this provision may have an anti-takeover effect with
respect to transactions not approved in advance by the board of directors,
including discouraging

                                       73
<PAGE>   80

attempts that might result in a premium over the market price for the shares of
common stock held by stockholders.

     Elimination of Stockholder Action By Written Consent. E.piphany's
certificate of incorporation eliminates the right of stockholders to act by
written consent without a meeting.

     Elimination of Cumulative Voting. E.piphany's certificate of incorporation
and bylaws do not provide for cumulative voting in the election of directors.
Cumulative voting provides for a minority stockholder to vote a portion or all
of its shares for one or more candidates for seats on the board of directors.
Without cumulative voting, a minority stockholder will not be able to gain as
many seats on E.piphany's board of directors based on the number of shares of
E.piphany stock that such stockholder holds than if cumulative voting were
permitted. The elimination of cumulative voting makes it more difficult for a
minority stockholder to gain a seat on E.piphany's board of directors to
influence the board of directors' decision regarding a takeover.

     Undesignated Preferred Stock. The authorization of undesignated preferred
stock makes it possible for the board of directors to issue preferred stock with
voting or other rights or preferences that could impede the success of any
attempt to change control of E.piphany. These and other provisions may have the
effect of deferring hostile takeovers or delaying changes in control or
management of E.piphany.

     Amendment of Charter Provisions. The amendment of any of the above
provisions would require approval by holders of at least 66 2/3% of the
outstanding common stock of E.piphany.

E.PIPHANY TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the E.piphany common stock is
Equiserve, Limited Partnership.

votes in connection with the election of directors. Subject to the preferential
rights of the Octane preferred stock, the holders of shares of Octane common

                                       74
<PAGE>   81

     Octane common stock has no preemptive or conversion rights or other
subscription rights. There are no redemption or sinking fund provisions
available to Octane common shareholders. All outstanding shares of Octane common
stock are fully paid and non-assessable.

OCTANE PREFERRED STOCK

outstanding of which 4,650,000 shares are designated as Series A preferred
stock, 4,778,780 shares are designated as Series B preferred stock and 3,522,540
shares are designated as Series C preferred stock. Octane preferred stock is
convertible into shares of Octane common stock on a one-for-one basis, subject
to adjustments, and, certain events will trigger automatic conversion of
Octane's preferred stock into common stock. Octane's preferred stock is held by
60 shareholders of record.

     Dividend Rights. Holders of Octane preferred stock are entitled to receive
dividends before holders of common stock in the following amounts per annum:
$0.1067 per share of Series A preferred stock, $0.2568 per share of Series B
preferred stock and $0.65444 per share of Series C preferred stock. Such
dividends are not cumulative and are paid only when and if declared by the
Octane board of directors.

     Liquidation Preference. In the event of any liquidation, dissolution or
winding up of Octane, such as the merger, holders of Octane preferred stock are
entitled to be paid first out of the assets of Octane available for distribution
before any amounts or assets are distributed among the holders of common stock.
Holders of preferred stock are entitled to receive $1.33 per share of Series A
preferred stock, $3.21 per share of Series B preferred stock and $8.18 per share
of Series C preferred stock, plus any accrued and unpaid dividends thereon. Any
remaining assets of Octane available for distribution to shareholders are to be
distributed among the holders of preferred stock and common stock pro rata based
on the number of shares of common stock held by each, assuming conversion of all
preferred stock into common stock, until:

     - holders of Series A preferred stock receive an aggregate of $4.00 per
       share of Series A preferred stock if such distribution takes place prior
       to January 27, 2001, or $6.6666 per share if such distribution takes
       place on or after January 27, 2001,

     - holders of Series B preferred stock receive an aggregate of $9.63 per
       share of Series B preferred stock if such distribution takes place prior
       to January 27, 2001, or $16.05 per share if such distribution takes place
       on or after January 27, 2001, and

     - holders of Series C preferred stock receive an aggregate of $24.54 per
       share of Series C preferred stock if such distribution takes place prior
       to January 27, 2001, or $40.90 per share if such distribution takes place
       on or after January 27, 2001.

     If assets remain in Octane after the above liquidation preferences are
fully satisfied, the holders of common stock shall receive all of the remaining
assets on a pro rata basis.

     Other Rights. Octane preferred stock is subject to broad-based,
weighted-average anti-dilution provisions in the event of additional issuances
of securities by Octane. Also, Octane is required to obtain the approval of the

certain corporate actions including actions impacting preferred stock and
corporate dispositions, sales and mergers.

COMPARISON OF CAPITAL STOCK OF E.PIPHANY AND OCTANE

     This section of the proxy statement/prospectus describes material
differences between the rights of holders of Octane capital stock and E.piphany
common 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 carefully read this entire document and the
other documents we refer to for a more complete understanding of the differences
between being a shareholder of Octane and being a stockholder of E.piphany.

     E.piphany is incorporated in the State of Delaware and Octane is
incorporated in the State of California. Following the merger, the surviving
corporation of the merger of Octane and Orchid Acquisition Corporation will be
governed by the California Corporations Code and E.piphany will continue to be
governed by the Delaware General Corporation Law. Shareholders of Octane,
however, will hold E.piphany common stock rather than Octane common stock.
Therefore, the rights of such shareholders will be governed by Delaware law and
the provisions of the E.piphany amended and restated certificate of
incorporation and the E.piphany bylaws, rather than the Octane amended and
restated articles of incorporation and the Octane bylaws.

     The following is a summary of the comparison of some provisions of
California law and Delaware law and the charters and bylaws of the respective
corporations. This summary does not purport to be complete and is qualified in
its entirety by reference to the corporate statutes of Delaware and California
and the corporate charters and bylaws of E.piphany and Octane.

PREFERRED STOCK

     E.piphany's certificate of incorporation provides that E.piphany's board of
directors is authorized to issue shares of undesignated preferred stock in one
or more series, and to fix the designations, powers, preferences and rights of
the shares of each series and any qualifications, limitations or restrictions
thereof.

     Octane's articles of incorporation provides that Octane's board of
directors is authorized to issue shares of designated preferred stock in three
series. The holders of preferred stock receive preferences as to dividends and
liquidation. The holders of preferred stock are entitled to a number of votes
equal to the number of shares of common stock into which the shares of preferred
stock could be converted at the record date for determination of the
shareholders entitled to vote on such matters.

AMENDMENT OF BYLAWS

     Under Delaware and California law, stockholders entitled to vote have the
power to adopt, amend or repeal bylaws. In addition, under Delaware and
California law a corporation may, in its certificate or articles of
incorporation, as the case may be, confer such power upon the board of
directors. The stockholders under both California and Delaware law always have
the power to adopt, amend or repeal bylaws, even though the board may also be
delegated such power. Each of E.piphany's and Octane's boards of directors is
expressly authorized to adopt, amend and repeal their respective bylaws by an
affirmative vote of a majority of the total number of authorized directors at
that time, regardless of any vacancies, except for certain changes to the number
of directors as described below in "Size of the Board of Directors."

AMENDMENT OF E.PIPHANY'S CERTIFICATE AND OCTANE'S ARTICLES

     Under Delaware law, a certificate of incorporation of a Delaware
corporation may be amended by approval of the board of directors of the
corporation and the affirmative vote of the holders of a majority of the
outstanding shares entitled to vote on the amendment, unless a higher vote is
required by the corporation's certificate of incorporation. Under E.piphany's
certificate of incorporation, certain provisions may be amended only with the
affirmative vote of the holders of at least two-thirds of the combined voting
power of all of the then-outstanding shares of E.piphany capital stock entitled
to vote, unless the amendment is approved by a majority of the directors of
E.piphany.

     Under California law, except for certain amendments such as stock splits,
the articles of incorporation may be amended by the approval of the board of
directors and a majority of the outstanding shares entitled to vote. Octane's
articles of incorporation contain provisions requiring a vote greater than that
required by California law to amend certain sections of Octane's articles of
incorporation. For example, Octane's articles of incorporation require a
two-thirds majority class vote of the preferred shareholders to convert all
shares of Octane preferred stock into shares of Octane common stock in
connection with the merger.

STOCKHOLDERS' ABILITY TO ACT BY WRITTEN CONSENT WITHOUT A MEETING

     The Octane bylaws allow for the Octane shareholders to act by written
consent without a meeting, whereas E.piphany's certificate of incorporation
eliminates the ability of E.piphany stockholders to act by written consent
without a meeting. The elimination of the ability of stockholders to act by
written consent could lengthen the amount of time required to take stockholder
actions by requiring all actions to occur at a duly noticed and formally called
stockholders' meeting. This lengthening of time has the potential to deter
hostile takeover attempts. If the ability of stockholders to act by written
consent is eliminated, a holder or group of holders controlling a majority in
interest of a corporation's capital stock, for example, would not be able to
amend such corporation's bylaws or remove its directors pursuant to a
stockholders' written consent. E.piphany's board of directors, chairman of the
board or president may call special meetings of E.piphany stockholders at any
time. E.piphany stockholders do not have the ability to call special meetings.
Octane's board of directors, chairman of the board, president, or the holders of
at least 10% of the outstanding shares of capital stock of Octane entitled to
vote may call special meetings of Octane shareholders.

SIZE OF THE BOARD OF DIRECTORS

     Delaware law provides that the board of directors of a Delaware corporation
shall consist of one or more members. The number of directors may be fixed by,
or in the manner provided in, the corporation's bylaws unless the certificate of
incorporation fixes the number of directors. E.piphany's certificate of
incorporation states that the number of directors of E.piphany will be fixed.
The number of directors may be changed by an amendment to the E.piphany bylaws
approved by its board of directors, by its stockholders or by a duly adopted
amendment to its certificate of incorporation. E.piphany's bylaws provide that
its board of directors will consist of seven directors. There are currently six
directors serving and one vacancy on the board.

     Under California law, although changes in the number of directors must in
general be approved by the shareholders, the board of directors may fix the
exact number of directors within a stated range set forth in the articles of
incorporation or bylaws, if the stated range has been approved by the
shareholders.

     Octane's board of directors currently consists of five seats, with four
directors currently serving on Octane's board of directors and one seat
currently vacant. The number of directors on Octane's board of directors may be
changed by Octane shareholders by a duly adopted amendment to the
                                       77
<PAGE>   84

articles of incorporation or by an amendment to the bylaws adopted by the vote
or written consent of holders of a majority of the outstanding shares entitled
to vote. However, an amendment reducing the fixed number or the minimum number
of directors to a number less than five (5) cannot be adopted if the votes cast
against its adoption at a meeting, or the shares not consenting in the case of
an action by written consent, are equal to more than 16 2/3% of the outstanding
shares entitled to vote thereon. Under Octane's articles of incorporation, the
holders of Series A, Series B and Series C preferred stock, voting together as a
class, have the right to elect two members of the board of directors of Octane.
Holders of common stock, voting together as a class, have the right to elect two
members of the board of directors. The other director is to be elected by the
holders of preferred stock and common stock, voting together on an as-converted
to common stock basis.

CLASSIFICATION OF BOARD OF DIRECTORS

     A classified board is one with respect to which a certain number of
directors, but not necessarily all, are elected on a rotating basis each year.
The Delaware General Corporation Law permits, but does not require, a classified
board of directors, pursuant to which the directors can be divided into as many
as three classes with staggered terms of office, with only one class of
directors standing for election each year. E.piphany's certificate of
incorporation and bylaws provide for a classified board of directors.
E.piphany's board of directors is divided into three classes designated as Class
I, Class II, and Class III, respectively. Directors are assigned to each class
in accordance with a resolution or resolutions adopted by the board of
directors. At the 2000 annual meeting of stockholders, the term of office of the
Class I directors will expire and Class I directors will be elected for a full
term of three years. At the 2001 annual meeting of stockholders, the term of
office of the Class II directors will expire and Class II directors will be
elected for a full term of three years. At the 2002 annual meeting of
stockholders, the term of office of the Class III directors will expire and
Class III directors will be elected for a full term of three years. At each
succeeding annual meeting of stockholders, directors will be elected for a full
term of three years to succeed the directors of the class whose terms expire at
such annual meeting.

     California law generally requires that directors be elected annually but
does permit a "classified" board of directors if the corporation is "listed." A
listed corporation is defined under California law as one (a) which is listed on
the New York or American Stock Exchange or (b) with a class of securities
designated as a national market system security on NASDAQ. If eligible,
California law permits corporations to provide for a board of directors divided
into as many as three classes by adopting an amendment to the articles of
incorporation or bylaws, which amendment must be approved by the shareholders.
Octane is not listed and its articles of incorporation and bylaws do not provide
for a classified board.

CUMULATIVE VOTING

     In an election of directors under cumulative voting, each share of stock
normally having one vote is entitled to a number of votes equal to the number of
directors to be elected. A stockholder may then cast all such votes for a single
candidate or may allocate them among as many candidates as the stockholder may
choose. Without cumulative voting, the holders of a majority of the shares
present at an annual meeting would have the power to elect all the directors to
be elected at that meeting, and no person could be elected without the support
of holders of a majority of the shares.

     Under Delaware law, cumulative voting in the election of directors is not
available unless specifically provided for in the certificate of incorporation.
E.piphany's certificate of incorporation does not provide for cumulative voting.

     California law provides that any shareholder is entitled to cumulate his or
her votes in the election of directors upon proper notice of his or her
intention to do so, except that a "listed"

                                       78
<PAGE>   85

corporation may eliminate cumulative voting with shareholder approval. If any
one shareholder gives such notice, all shareholders may cumulate their votes.
The Octane bylaws permit any person entitled to vote at an election for
directors to cumulate the votes to which such person is entitled. However, no
shareholder is entitled to cumulate his or her votes unless the candidates for
which the shareholder is voting have been placed in nomination prior to the
voting and a shareholder has given notice at the meeting, prior to the vote, of
an intention to cumulate votes.

REMOVAL OF DIRECTORS

     Under Delaware law, a director of a corporation that does not have a
classified board of directors or cumulative voting may be removed without cause
by a majority stockholder vote. A director of a corporation with a classified
board of directors can be removed only for cause unless the certificate of
incorporation otherwise provides. E.piphany's directors, or the entire E.piphany
board, may be removed with cause by the affirmative vote of the holders of at
least a majority of the outstanding shares of E.piphany common stock entitled to
vote in the election of directors. "Cause" is not defined in E.piphany's
certificate of incorporation or bylaws.

     Under California law, any director, or the entire board of directors, may
be removed, with or without cause, with the approval of a majority of the
outstanding shares entitled to vote. However, no directors may be removed
(unless the entire board is removed) if the number of votes cast against the
removal would be sufficient to elect the director under cumulative voting.
Octane's articles of incorporation permit removal of a director, with or without
cause, by the vote or consent of the holders of the outstanding class or series
with voting power to elect the director in accordance with the California
Corporations Code. "Cause" is not defined in Octane's articles of incorporation
or bylaws.

FILLING VACANCIES IN THE BOARD OF DIRECTORS

     Vacancies and newly created directorships in E.piphany's board of directors
resulting from any increase in the authorized number of directors elected by all
of the stockholders having the right to vote as a single class may be filled by
a majority of the directors then in office, although less than a quorum, or by a
sole remaining director. However, a vacancy created by the removal of a director
by the vote of the stockholders or by court order may be filled only by the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present -- which shares, voting affirmatively,
also constitute a majority of the required quorum. If, at the time of filling
any vacancy or any newly created directorship of E.piphany, the directors then
in office constitute less than a majority of the whole board -- as constituted
immediately prior to any such increase -- then the Delaware Court of Chancery
may, upon application of any stockholder or stockholders holding at least 10% of
the total number of the shares then outstanding having the right to vote for
such directors, summarily order an election to be held to fill any such
vacancies or newly created directorships, or to replace the directors chosen by
the directors then in office, which election will be governed by the provisions
of the Delaware General Corporation Law as far as applicable.

     Any vacancies on Octane's board of directors resulting from any increase in
the number of authorized directors or by the departure of a director (other than
vacancies created by the removal of a director by the vote or written consent of
the shareholders or by court order), may be filled by a majority of the
remaining members of the Octane board of directors, even though less than a
quorum, or by a sole remaining director. If a vacancy on the board of directors
is to be filled by the Octane board of directors, only a director or directors
elected by the same class of shareholders as those who would be entitled to vote
to fill the vacancy, if any, will vote to fill the vacancy. A vacancy created by
a removal of a director by the vote or written consent of the shareholders or by
court order may be filled only by the affirmative vote of a majority of the
shares represented and voting at a duly

                                       79
<PAGE>   86

held meeting at which a quorum is present -- which shares, voting affirmatively,
also constitute a majority of the required quorum -- or by the unanimous written
consent of all shares entitled to vote thereon.

PAYMENT OF DIVIDENDS AND REPURCHASES OF SHARES

     Delaware law permits a corporation, unless otherwise restricted by its
certificate of incorporation, to declare and pay dividends out of surplus or, if
there is no surplus, out of net profits for the fiscal year in which the
dividend is declared, and/or for the preceding fiscal year, as long as the
amount of capital of the corporation is not less than the aggregate amount of
the capital represented by the issued and outstanding stock of all classes
having a preference upon the distribution of assets. In addition, Delaware law
generally provides that a corporation may redeem or repurchase its shares only
if the redemption or repurchase would not impair the capital of the corporation.
The ability of a Delaware corporation to pay dividends on, or to make
repurchases or redemptions of, its shares is dependent on the financial status
of the corporation standing alone and not on a consolidated basis. In
determining the amount of surplus of a Delaware corporation, the assets of the
corporation, including stock of subsidiaries owned by the corporation, must be
valued at their fair market value as determined by the board of directors,
regardless of their historical book value.

     Under California law, a corporation may not make any distribution
(including dividends, whether in cash or other property, and repurchases of its
shares) unless either the corporation's retained earnings immediately prior to
the proposed distribution equal or exceed the amount of the proposed
distribution or, immediately after giving effect to such distribution, the
corporation's assets (exclusive of goodwill, capitalized research and
development expenses and deferred charges) would be at least equal to 125% of
its liabilities (not including deferred taxes, deferred income and other
deferred credits), and the corporation's current assets, as defined, would be at
least equal to its current liabilities (or 125% of its current liabilities if
the average pre-tax and pre-interest earnings for the preceding two fiscal years
were less than the average interest expenses for such years). These tests are
applied to California corporations on a consolidated basis. Under California
law, there are certain exceptions to the foregoing rules for repurchases of
shares in connection with certain rescission actions or pursuant to certain
employee stock plans.

DISSENTERS' AND APPRAISAL RIGHTS

     Under both California and Delaware law, a stockholder of a corporation
participating in certain major corporate transactions may, under varying
circumstances, be entitled to appraisal rights under Delaware law, or,
dissenters' rights under California law, pursuant to which the stockholder may
receive cash in the amount of the fair market value of the shares held by the
stockholder (as determined by a court or by agreement of the corporation and the
stockholder) in lieu of the consideration the stockholder would otherwise
receive in the transaction.

     Under Delaware law, appraisal rights are not available to:

     - stockholders with respect to a merger or consolidation by a corporation
       whose shares are 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 are held of record by more than 2,000 holders if such stockholders
       receive only shares of the surviving corporation or shares of any other
       corporation having shares that are 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 are held of record by more than 2,000 holders; or

     - stockholders of a corporation surviving a merger if no vote of the
       stockholders of the surviving corporation is required to approve the
       merger because, among other things, the number of
                                       80
<PAGE>   87

       shares to be issued in the merger does not exceed 20% of the shares of
       the surviving corporation outstanding immediately prior to the merger and
       if certain other conditions are met.

     Delaware law also does not provide stockholders of a corporation with
appraisal rights when the corporation acquires another business through the
issuance of its stock:

     - in exchange for the assets of the business to be acquired,

     - in exchange for the outstanding stock of the corporation to be acquired,
       or

     - in a merger of the corporation to be acquired with a subsidiary of the
       acquiring corporation.

     California law treats these kinds of acquisitions in the same manner as a
direct merger of the acquiring corporation with the corporation to be acquired.

     The limitations on the availability of dissenters' rights under California
law are different from those under Delaware law. Shareholders of a California
corporation whose shares are listed on a national securities exchange or on a
list of over-the-counter margin stocks issued by the Board of Governors of the
Federal Reserve System generally do not have dissenters' rights unless the
holders of at least 5% of the class of outstanding shares claim the right.
Dissenters' rights are not available, however, if the shareholders of a
corporation or the corporation itself, or both, immediately prior to a
reorganization own, immediately after the reorganization, more than five-sixths
of the voting power of the surviving or acquiring corporation or its parent.

     Dissenters' rights are available to shareholders of Octane with respect to
the merger. For a more complete description of these rights, see the section
entitled "Dissenters' Rights" and reference Sections 1300 through 1312 of the
California Corporations Code attached as Annex IV to this proxy
statement/prospectus.

INSPECTION OF BOOKS AND RECORDS

     Both California and Delaware law allow any stockholder to inspect the
stockholder list for a purpose reasonably related to such person's interest as a
stockholder. California law provides, in addition, an absolute right to inspect
and copy the corporation's shareholder list by a person or persons holding 5% or
more of a corporations voting shares, or any shareholder or shareholders holding
1% or more of such shares who has filed a Schedule 14A with the Commission
relating to the election of directors. Delaware law does not provide for any
such absolute right of inspection.

LIMITATION OF LIABILITY OF DIRECTORS

     California and Delaware laws have similar provisions and limitations
respecting indemnification by a corporation of its officers, directors and
employees. Both California and Delaware law permit a corporation to adopt a
provision in its charter documents eliminating the liability of a director to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided such liability does not arise from certain
proscribed conduct, including intentional misconduct and breach of the duty of
loyalty.

INDEMNIFICATION

     The Delaware General Corporation Law generally permits indemnification of
expenses incurred in the defense or settlement of a derivative or third-party
action, provided there is a determination by a disinterested quorum of the
directors, by independent legal counsel or by the stockholders, that the person
seeking indemnification acted in good faith and in a manner reasonably believed
to be in or (in contrast to California law) not opposed to the best interests of
the corporation and, with respect to a criminal proceeding, which such person
had no reasonable cause to believe his or her conduct

                                       81
<PAGE>   88

was unlawful. Without court approval, however, no indemnification may be made in
respect of any derivative action in which such person is adjudged liable to the
corporation. Delaware law requires indemnification of expenses when the
individual being indemnified has successfully defended the action on the merits
or otherwise.

     The E.piphany bylaws provide that E.piphany will indemnify its directors
and executive officers and may indemnify other offices to the maximum extent
permitted by law. Under E.piphany's bylaws, indemnified parties are entitled to
indemnification to the extent permitted by law for actions made in good faith
and in a manner such person reasonably believes to be in, or not opposed to, the
best interests of E.piphany. The E.piphany bylaws also require E.piphany to
advance litigation expenses in the case of stockholder derivative actions or
other actions, against an undertaking by the indemnified party to repay such
advances if it is ultimately determined that the indemnified party is not
entitled to indemnification. E.piphany also has indemnification agreements with
its officers and directors.

     The California Corporations Code permits indemnification of expenses
incurred in derivative or third-party actions, except that with respect to
derivative actions (a) no indemnification may be made when a person is adjudged
liable to the corporation in the performance of that person's duty to the
corporation and its shareholders, unless a court determines such person is
entitled to indemnity for expenses, and then such indemnification may be made
only to the extent that the court shall determine, and (b) no indemnification
may be made without court approval in respect of amounts paid in settling or
otherwise disposing of an action or expenses incurred in defending an action
which is settled or otherwise disposed of without court approval.

     Indemnification is permitted by California law only for acts taken by the
person seeking indemnification in good faith and in a manner the person
reasonably believed to be in the best interests of the corporation and its
shareholders and with respect to a criminal proceeding, which such person had no
reasonable cause to believe the conduct of the person was unlawful, as
determined by a majority vote of a quorum of disinterested directors,
independent legal counsel (if a quorum of disinterested directors is not
obtainable), a majority vote of a quorum of the shareholders (excluding shares
owned by the indemnified party), or the court handling the action. California
law requires indemnification when the individual has successfully defended the
action on the merits. California corporations may include in their articles of
incorporation a provision which extends the scope of indemnification through
agreements, bylaws or other corporate actions beyond that specifically
authorized by law. The Octane bylaws include a provision that provides Octane
with the authority to indemnify its agents to the fullest extent permitted by
California law.

STOCKHOLDER APPROVAL OF CERTAIN BUSINESS COMBINATIONS

     The Delaware General Corporation Law makes it more difficult to effect
certain transactions between a corporation and a person or group who or which
owns 15% or more of the corporation's outstanding voting stock (including any
rights to acquire stock pursuant to an option, warrant, agreement, arrangement
or understanding, or upon the exercise of conversion or exchange rights, and
stock with respect to which the person has voting rights only), or is an
affiliate or associate of the corporation and was the owner of 15% or more of
such voting stock at any time within the previous three years (excluding persons
who became 15% stockholders by action of the corporation alone). For a period of
three years following the date that a stockholder became a holder of 15% or more
of the corporation's outstanding voting stock, the following types of
transactions between the corporation and the 15% stockholder are prohibited
(unless certain conditions, described below, are met):

     - mergers or consolidations,

     - sales, leases, exchanges or other transfers of 10% or more of the
       aggregate assets of the corporation,

                                       82
<PAGE>   89

     - issuances or transfers by the corporation of any stock of the corporation
       which would have the effect of increasing the 15% stockholder's
       proportionate share of the stock of any class or series of the
       corporation,

     - receipt by the 15% stockholder of the benefit (except proportionately as
       a stockholder) of loans, advances, guarantees, pledges or other financial
       benefits provided by the corporation, and

     - any other transaction which has the effect of increasing the
       proportionate share of the stock of any class or series of the
       corporation which is owned by the 15% stockholder.

     The three-year ban does not apply if either the proposed transactions or
the transaction by which the 15% stockholder became a 15% stockholder is
approved by the board of directors of the corporation prior to the date the
stockholder became a 15% stockholder. Additionally, a 15% stockholder may avoid
the statutory restriction if, upon the consummation of the transaction whereby
the stockholder became a 15% stockholder, the stockholder owns at least 85% of
the outstanding voting stock of the corporation without regard to those shares
owned by the corporation's officers and directors or certain employee stock
plans. Business combinations are also permitted within the three year period if
approved by the board of directors and, at an annual or special meeting, by the
holders of 66 2/3% of the voting stock not owned by the 15% stockholder.

     A corporation may, at its option, exclude itself from the coverage of this
Delaware law provision by providing in its certificate of incorporation or
bylaws at any time to exempt itself from coverage, provided that a bylaw or
charter amendment cannot become effective for 12 months after the amendment is
adopted.

     In addition, any transaction is exempt from the statutory ban if it is
proposed at a time when the corporation has proposed, and a majority of certain
continuing directors of the corporation have approved, a transaction with a
party who is not a 15% stockholder of the corporation (or who became such with
board approval) if the proposed transaction involves:

     - certain mergers or consolidations involving the corporation,

     - a sale or other transfer of over 50% of the aggregate assets of the
       corporation, or

     - a tender or exchange offer for 50% or more of the outstanding voting
       stock of the corporation.

STOCKHOLDER VOTING ON MERGERS AND SIMILAR TRANSACTIONS

     The laws of both California and Delaware generally require that a majority
of the shareholders of both acquiring and target corporations approve statutory
mergers. Delaware law 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 stock of the surviving corporation outstanding before the
       merger is an identical outstanding or treasury share 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 outstanding immediately prior to
       the merger.

     California law contains a similar exception to its voting requirements for
reorganization where shareholders, or the corporation itself, or both,
immediately prior to the reorganization will own immediately after the
reorganization equity securities constituting more than five-sixths of the
voting power (assuming the conversion of convertible equity securities) of the
surviving or acquiring corporation or its parent entity.

                                       83
<PAGE>   90

     The laws of both California and Delaware also generally require that a sale
of all or substantially all of the assets of a corporation be approved by a
majority of the voting shares of the corporation transferring such assets.

     With certain exceptions, California law also requires that mergers,
reorganizations, and similar transactions be approved by a majority vote of each
class of shares outstanding. In contrast, Delaware law generally does not
require class voting, except for amendments to the certificate of incorporation
that change the number of authorized shares or the par value of shares of a
specific class or that adversely affect such class of shares.

LOANS TO DIRECTORS, OFFICERS AND EMPLOYEES

     Under Delaware law, a corporation may make loans to, guarantee the
obligations of, or otherwise assist its officers or other employees and those of
its subsidiaries when such action, in the judgment of the directors, may
reasonably be expected to benefit the corporation.

     Under California law, any such loan or guaranty to or for the benefit of a
director or officer of the corporation or any of its subsidiaries requires
approval of the shareholders unless such loan or guaranty is provided under a
plan approved by shareholders owning a majority of the outstanding shares of the
corporation. In addition, under California law, shareholders of any corporation
with 100 or more shareholders of record may approve a bylaw authorizing the
board of directors alone to approve a loan or guaranty to or on behalf of an
officer (whether or not a director) if the board determines that such a loan or
guaranty may reasonably be expected to benefit the corporation.

INTERESTED DIRECTOR TRANSACTIONS

     Under both California and Delaware law, certain contracts or transactions
in which one or more of a corporation's directors has an interest are not void
or voidable because of such interest provided that certain conditions, such as
obtaining the required approval and fulfilling the requirements of good faith
and full disclosure, are met. With certain exceptions, the conditions are
similar under California and Delaware law. Under California and Delaware law,
(a) either the stockholders or the board of directors must approve any such
contract or transaction after full disclosure of the material facts, and, in the
case of board of director approval, the contract or transaction must also be
"just and reasonable" (in California) or "fair" (in Delaware) to the
corporation, or (b) the contract or transaction must have been just and
reasonable or fair as to the corporation at the time it was approved. In the
latter case. California law explicitly places the burden of proof on the
interested director. Under California law, if shareholder approval is sought,
the interested director is not entitled to vote his or her shares at a
shareholder meeting with respect to any action regarding such contract or
transaction. If board of director approval is sought, the contract or
transaction must be approved by a majority vote of a quorum of the directors,
without counting the vote of any interested directors (except that interested
directors may be counted for purposes of establishing a quorum). Therefore,
certain transactions that the board of directors of a California corporation
might not be able to approve because of the number of interested directors could
be approved by a majority of the disinterested directors of a Delaware
corporation although less than a majority of a quorum.

STOCKHOLDER DERIVATIVE SUIT

     The Delaware General Corporation Law provides that a person may only bring
a derivative action on behalf of the corporation if the person was a stockholder
of the corporation at the time of the transaction in question or his or her
stock thereafter devolved upon him or her by operation of law.

     The California Corporations Code provides that a shareholder bringing a
derivative action on behalf of a corporation need not have been a shareholder at
the time of the transaction in question, provided that certain criteria are met.
California law also provides that the corporation or the

                                       84
<PAGE>   91

defendant in a derivative suit may, under certain circumstances, make a motion
to the court for an order requiring the plaintiff shareholder to furnish a
security bond. Delaware does not have a similar bonding requirement.

DISSOLUTION

     Under Delaware law, a dissolution must be approved by stockholders holding
100% of the total voting power or the dissolution must be initiated by the board
of directors and approved by a simple majority of the stockholders of the
corporation. In the event of such a board-initiated dissolution, Delaware law
allows a Delaware corporation to include in its certificate of incorporation a
supermajority voting requirement in connection with dissolutions.

     Under California law, shareholders holding 50% or more of the voting power
may authorize a corporation's dissolution, with or without the approval of the
corporation's board of directors and this right may not be modified by the
articles of incorporation.

RECENT EVENTS

     On January 4, 2000, E.piphany acquired RightPoint Software, Inc. in a
merger transaction. RightPoint develops and markets real-time marketing
software. RightPoint's software solutions enable companies to optimize and
present marketing offers, promotions, and communications while a customer is
interacting with a web site, call center agent or other point of customer
interaction. RightPoint's real-time marketing software applications provide a
single integrated view of the customer across multiple channels, allowing
consistent marketing messages and promotions to customers regardless of which
channel a customer is using. In connection with the acquisition, E.piphany
issued approximately 3.1 million shares of its common stock. In addition,
options and warrants of RightPoint were converted into options and warrants to
purchase approximately 530,000 shares of E.piphany's common stock. This
transaction has been accounted for under the purchase method of accounting.

     On January 20, 2000, E.piphany completed a follow-on public offering of
3,700,000 shares of common stock. E.piphany sold 1,993,864 shares of its common
stock and the selling stockholders sold 1,706,136 shares of E.piphany's common
stock. In addition, on February 15, 2000 the underwriters exercised their option
to purchase 418,500 shares, of which 104,342 were from E.piphany and 314,158
were from selling stockholders, to cover over-allotments of shares. E.piphany
expects to use the net proceeds from the offering of $356 million for working
capital and general corporate purposes. E.piphany may also use a portion of the
net proceeds to acquire complementary products, technologies or businesses.

     On March 27, 2000, E.piphany entered into a definitive agreement to acquire
privately held iLeverage Corporation, a start-up company that is developing
marketing solutions for digital marketplaces, for 181,649 shares of E.piphany
common stock. The acquisition will be accounted for as a purchase and is subject
to customary closing conditions, including the approval of iLeverage
stockholders.

     On April 14, 2000, E.piphany entered into a definitive agreement to acquire
privately held eClass Direct, an application service provider of
permission-based e-mail marketing services, for approxi-
                                       86

mately 750,000 shares of E.piphany common stock. The acquisition will be
accounted for as a purchase and is subject to customary closing conditions,
including the approval of eClass Direct stockholders.

INDUSTRY BACKGROUND

     The Internet is fundamentally changing the way businesses interact with
their customers and suppliers. Consumers can use the Internet to more quickly
evaluate products and prices from a wide range of vendors without regard to
geographical constraints. At the same time, companies across a variety of
industries are using the Internet to redefine the way that goods and services
are marketed, sold and distributed.

     To remain competitive in this dynamic business environment, many companies
are seeking to increase the longevity and profitability of their customer
relationships. E.piphany believes companies that improve their understanding of
their customers can gain the loyalty of their most profitable customers by
personalizing products, services and related interactions based on each
customer's characteristics and preferences. Furthermore, when companies
understand individual customer preferences, they can market complementary
products, known as "cross-selling," or market higher-end products, known as
"up-selling." To execute on these marketing strategies, companies need to
establish a single view of each customer across all of the company's various
departments, distribution channels and points of customer interaction. Companies
must then leverage this knowledge to market to customers through proactive
marketing campaigns, as well as by making marketing decisions in real time when
a customer initiates contact with the company. Finally, to better serve
customers, companies can use their knowledge of their customers to better
anticipate customer demand and optimize their processes for fulfilling customer
orders. For example, a company that identifies that many customers prefer a
particular product can increase inventories of that product to meet anticipated
demand.

     Over the past two decades, companies have invested in software applications
that reduce costs by automating business processes. AMR Research, an industry
and market analysis firm, estimates that, from 1995 through 1998, companies
spent more than $56 billion on industrial enterprise software applications that
are focused on automating sales, support, manufacturing, distribution and
finance processes. More recently, companies have begun investing in Internet
infrastructure software, including systems that enable commercial transactions
over the Web, as well as systems that monitor and track customers' behavior on
Web sites. Many companies also continue to operate older, custom-built systems
that automate critical business processes, such as order processing and
accounting. All of these applications have allowed companies to collect and
store enormous volumes of customer data, including customer demographic
information, historical purchasing information or delivery specifications. This
data is often augmented by marketing data from third-party data providers.

     Despite the vast amounts of data generated, these applications remain
focused on automating business processes, rather than helping companies better
understand their customers or manage marketing campaigns. Moreover, because
these data reside in disparate computer systems in different departments or are
delivered from third parties, combining and analyzing this information to
provide a single view of the customer is a significant challenge. For example, a
company may have over time acquired sales, customer service, and distribution
software applications, each operating on a different computer system. In
addition, many companies' Internet commerce systems operate independently of
systems that automate their traditional sales channels and fulfillment
processes. Because these applications and systems serve different purposes, they
collect vastly different types of customer data. To analyze and act on disparate
corporate data, many companies have attempted to integrate multiple software
tools designed to either extract data from various software systems, store it in
a central repository, analyze the data or manage marketing campaigns. Many of
these internally assembled

                                       87
<PAGE>   94

software systems require substantial amounts of time to integrate and customize,
making them expensive to implement and maintain. Moreover, these tools often
have complex user interfaces that are not accessible to all business users in a
company. Finally, these tools are typically not able to collect and analyze data
in real time to rapidly make marketing offers when a customer initiates contact
with the company.

     To allow all business users within a company to better understand and act
on customer information collected from multiple sources, companies need new
software solutions. These software solutions should be:

     - Focused on establishing, maintaining and improving customer
       relationships. Software should allow companies to identify and
       differentiate their current and potential customers and act on that
       knowledge to provide products, services, and related interactions
       personalized to each customer's preferences.

     - Deployable to all business users and points of interaction with
       customers. Software should be designed to offer the ease of use and
       availability of the Web to enable all business users -- not just
       information technology professionals and specialized analysts -- to
       access, understand and act on customer information. Additionally,
       software should easily integrate with companies' existing software to
       collect all relevant customer information and enable personalized
       interactions at each point of customer interaction.

     - Packaged to offer faster and less expensive implementation. Software
       should minimize the time and expense of implementation and maintenance by
       including in a single integrated system all of the technologies required
       to extract, store, analyze and act on customer data. In addition, the
       software should be designed to solve specific business problems without
       substantial customization.

     - Designed to generate marketing recommendations in real time. Software
       should enable companies to market to customers in real time during
       interactions initiated by the customer, such as Web site visits or
       contact with a customer support call center. This capability requires
       software systems to collect and analyze customer information and then
       immediately make a personalized marketing recommendation in real time.

THE E.PIPHANY SOLUTION

     Companies can use E.piphany's software to establish, maintain and
continually improve customer relationships across both Internet and traditional
sales, marketing and distribution channels. The E.piphany E.4 System allows
companies to profile customers' characteristics and preferences by collecting
and analyzing data from their existing software systems and third party data
providers. Business users within these companies can then act on this
information by using E.piphany's E.4 System to design and execute marketing
campaigns as well as personalize products, services and related interactions.
E.piphany believes that its software is differentiated by its combination of the
following characteristics:

     Software designed to establish, maintain and improve customer
relationships. E.piphany's software helps companies establish, maintain and
improve customer relationships by:

     - Identifying customers. E.piphany's software can be used by companies to
       better identify their customers by aggregating and analyzing data from
       existing software systems as well as from third-party data providers,

     - Differentiating customers. E.piphany's software allows companies to
       differentiate their customers by analyzing customer groups according to
       demographics, profitability, length of sales cycle, cross-sell success
       rates and other company-defined criteria,

                                       88
<PAGE>   95

     - Interacting with customers more personally. E.piphany's software helps
       companies to extend customer information to all employees that interact
       with customers as well as integrate this information with Internet
       infrastructure software that generates Web pages and e-mail. Moreover,
       E.piphany's software can be used to design and execute marketing
       campaigns that tailor marketing messages to each customer based on his or
       her specific characteristics and preferences, and

     - Personalizing products, services and related interactions. E.piphany's
       software helps companies collect and analyze the data required to
       personalize products, services and related interactions based on customer
       characteristics and preferences. In addition, companies can use
       E.piphany's software to better anticipate customer demand and to manage
       their processes for fulfilling orders in a more efficient manner.

     Web-based design to promote ease of use and wide-scale deployment to
business users. E.piphany's software offers an easy to use interface that is
similar to those used on most Web sites. The interface is accessed by business
users across a corporate network or the Internet using a Web browser, such as
Microsoft Internet Explorer. The software is installed by the customer in a
central location, either on the customer's own computer servers or on those of a
third-party hosting service. This Web-based design does not require E.piphany's
software to be installed on each user's computer, which reduces the costs of
deploying and maintaining software.

     Packaged software for faster and less expensive implementation. E.piphany's
software solutions are integrated to combine all of the technologies required to
collect and analyze customer data and manage marketing campaigns. As a result,
companies do not need to combine multiple vendors' software tools -- each of
which offers only limited capabilities -- into a single software solution and
then customize this software solution to meet their needs. E.piphany's software
solutions can generally be implemented in 16 weeks or less.

     Designed to generate marketing recommendations in real time. E.piphany's
software has been designed to generate marketing recommendations in real time
during interactions initiated by a customer. For example, the E.piphany E.4
System can collect data while a customer navigates a company's Web site or
speaks to a call center operator. E.piphany's software immediately analyzes that
data along with existing customer data to determine a customized marketing offer
to present to the customer. The offer is then delivered through integration at
the point of customer contact, such as dynamically presenting Web site content
or presenting a script to a call center operator within their existing call
center software application.

E.piphany E.4 System software solutions. Experience gained by E.piphany's
professional services organization through repeated implementation of
E.piphany's products is routinely conveyed to E.piphany's research and
development staff. E.piphany's research and development staff then uses this
experience to design new features into new releases of its software.

E.PIPHANY E.4 SYSTEM TECHNOLOGY

     The E.piphany E.4 System includes core technologies that enable E.piphany's
software solutions to extract, manage and analyze data from existing systems as
well as manage marketing campaigns. These software technologies allow
E.piphany's internal research and development organization to rapidly build and
deploy new software solutions as market opportunities arise, without
re-developing and configuring the underlying technologies. The major elements of
the E.piphany E.4 System's core technologies include:

     EpiCenter. EpiCenter is the E.piphany E.4 System software technology
E.piphany developed for storing and managing data. E.piphany's software
solutions utilize EpiCenter to retrieve the data that they require to perform
their analysis and distributed database marketing. Key functional elements of
EpiCenter include:

     - Adaptive Schema Generator. The Adaptive Schema Generator is the software
       technology that E.piphany developed and market as a part of the E.piphany
       E.4 System. It automatically reconfigures EpiCenter, based on high-level
       specifications, each time a customer's software solutions are modified.
       This technology enables rapid customization of E.piphany's products to
       meet the specific and dynamic business needs of E.piphany's customers and
       allows system administrators to avoid having to manage complex data
       storage design tasks.

     - Metadata integration. All of the components of the E.piphany E.4 System
       are integrated through E.piphany's metadata, which is a high-level,
       software-based description of a customer's E.piphany E.4 System and the
       data which resides in that system. Generic metadata is included in the
       E.piphany E.4 System when shipped, and is continually updated by the
       E.piphany E.4 System as consultants or users make changes to any portion
       of the system. As a result, when new data elements or functions are added
       to any software component of a customer's E.piphany E.4 System, all other
       software components are able to recognize the change and adapt
       accordingly.

                                       93
<PAGE>   100

     - Accelerators. E.piphany has integrated into the E.piphany E.4 System
       mathematical formulas called accelerators that improve the performance of
       E.piphany's software by pre-computing some information, creating special
       indices and providing "hints" to the system on how to optimize the
       processing of user queries.

     Data extraction and transformation. The E.piphany E.4 System offers a
powerful approach to extracting data from various sources and transforming that
data before loading it into EpiCenter. Central to this capability are
E.piphany's Packaged Semantic Transformations, which are rules that change
customer data into a format well-suited for data analysis by business users.

     Software application server. E.piphany's software application server is the
software technology that E.piphany developed to manage the mathematical formulas
that are used to analyze data in response to user queries. In addition, the
software application server generates the user interface that end-users interact
with through their Web browsers.

     Real-Time Personalization Solution. E.piphany's Real-Time Personalization
Solution executes the marketing campaigns developed by end users for real-time
marketing recommendations. When a customer makes contact with the company
through, for example, a Web site or a call center, E.piphany's Real-Time
Campaign Server accesses existing customer information, pre-defined campaigns
and information gathered during the current interaction to provide the most
appropriate recommendation to the customer.

RELATIONSHIPS AND ALLIANCES

     An important element of E.piphany's strategy is to establish relationships
and alliances to assist E.piphany in marketing, selling and implementing
E.piphany's software solutions. These relationships and alliances fall into the
following four categories:

     Consulting and implementation relationships. E.piphany works with Cambridge
Technology Partners, Ernst & Young and KPMG through subcontractor relationships
whereby these firms implement E.piphany's software on customers' computer
systems. In return for the services provided under these subcontractor
agreements, E.piphany pays fees to these entities and provides personnel and
technical resources to support their implementation of E.piphany's software. In
order to improve their opportunity to generate service fees from E.piphany's
customers, each of these entities has committed resources to training their
consultants on E.piphany's products, co-marketing E.piphany's products with
their services and incorporating E.piphany's products into their customer
relationship management marketing strategies. E.piphany has a contractual
relationship with Marketing 1:1 -- a marketing consulting firm -- under which
they provide consulting services to E.piphany and co-market and promote
E.piphany's software. In return, E.piphany pays consulting fees and other
compensation to the firm as well as fees for customer referrals. Cambridge
Technology Partners, KPMG and Marketing 1:1 are also investors in E.piphany.
E.piphany believes that these relationships will facilitate the adoption and
deployment of E.piphany's software and expand the capabilities of E.piphany's
software to target specific industries.

     Platform relationships. To help ensure that E.piphany's products are based
on industry standards and take advantage of current and emerging technologies,
E.piphany has formed relationships with vendors of software and hardware
technology platforms. E.piphany currently maintains platform relationships with
Hewlett-Packard, Microsoft, Oracle and Sun Microsystems. These companies
voluntarily provide E.piphany with early releases of new technology platforms,
education related to those platforms and limited access to their technical
resources to facilitate adoption of their technology. As a result, E.piphany is
able to more easily integrate E.piphany's products with these vendors'
platforms, and E.piphany can also anticipate required changes to E.piphany's
products based on new versions of these vendors' platforms. E.piphany believes
that these

                                       94
<PAGE>   101

relationships allow E.piphany to focus on E.piphany's core competencies,
simplify the task of designing and developing E.piphany's software and reduce
the time it takes E.piphany to make E.piphany's software compatible with their
software or hardware.

     Technology relationships. E.piphany has formed relationships with vendors
of complementary software products. These relationships consist of non-exclusive
contractual agreements to co-market each other's products and share technical
resources in order to better integrate each other's products. These agreements
also provide, in some instances, for the payment of referral fees to each other
for customer referrals. E.piphany currently has such agreements with Art
Technology Group, BroadVision, FirePond and Vignette, all of which are providers
of Internet infrastructure software.

     Reseller and applications service provider relationships. E.piphany has
entered into contractual reseller agreements with vendors under which E.piphany
sells software solutions to them for resale to their customers. E.piphany
believes that these relationships will extend its sales presence in new and
existing markets. E.piphany has entered into reseller agreements with Acxiom and
Harte-Hanks -- two providers of customer data and strategic marketing
services -- and a reseller agreement with Pivotal Software -- a vendor of sales
force automation and customer support software. E.piphany has also recently
entered into a relationship with Corio -- an Internet-based application service
provider. Under these agreements, E.piphany sells its software solutions to
these companies at a discount from E.piphany's list prices, provide some
marketing and training support and must provide advance notice of price
increases. Each of these companies has committed resources to training their
employees, developing co-marketing programs and incorporating E.piphany's
products into their customer relationship management marketing strategies.
E.piphany provides sales materials, training and support services to these
resellers on the implementation of E.piphany's software solutions. E.piphany
also has contractual relationships with Exactis.com, Bullseye Interactive and
Interrelate under which these companies host E.piphany's software solutions as
Internet-based application service providers. E.piphany has not yet generated
any significant revenues from any of these reseller and applications service
provider agreements.

CUSTOMERS

     E.piphany's customers represent large global institutions from industries
such as high technology, financial services, communications, and internet
commerce. For the quarter ended March 31, 2000 no individual customer accounted
for more than 10% of E.piphany's total revenues. For the year ended December 31,
1999, Sallie Mae accounted for 11% of E.piphany's total revenues. For the year
ended December 31, 1998, Autodesk, Charles Schwab, Hewlett-Packard, KPMG and
Macromedia, accounted for 30%, 17%, 16%, 11% and 11%, respectively, of
E.piphany's total revenues.

RESEARCH AND DEVELOPMENT

     E.piphany's research and development organization is responsible for
developing new software products, product architecture, core technologies,
product testing, quality assurance and ensuring the compatibility of E.piphany's
products with hardware and software platforms. In addition, this organization
supports some pre-sale and customer support activities. E.piphany's research and
development organization is divided into teams consisting of development
engineers, product managers, quality assurance engineers and technical writers.
In addition, E.piphany's professional services staff helps E.piphany's research
and development organization identify potential new product features.

     E.piphany's research and development staff consisted of 86 employees as of
March 31, 2000. E.piphany's total expenses for research and development were
$7.1 million for the year ended December 31, 1999 and $3.8 million for the year
ended December 31, 1998. E.piphany expects that

                                       95
<PAGE>   102

research and development expenses will increase in absolute dollars and may
increase as a percentage of revenue in future periods.

SALES, MARKETING AND DISTRIBUTION

     To date, E.piphany has marketed its products primarily through its direct
sales force. However, E.piphany intends to expand its sales channels through
additional relationships with systems integrators and value-added resellers. In
selling E.piphany's products, E.piphany typically approaches both business users
and information technology professionals with an integrated team from
E.piphany's sales and professional services organizations. Initial sales
activities typically include a demonstration of E.piphany's product capabilities
followed by one or more detailed technical reviews. E.piphany also seeks to
establish relationships and alliances with major industry vendors that will add
value to E.piphany's products and expand E.piphany's distribution opportunities.
E.piphany's sales and marketing organization consisted of 117 employees as of
March 31, 2000.

     E.piphany uses a variety of marketing programs to build market awareness of
E.piphany's company, E.piphany's brand name and E.piphany's products, as well as
to attract potential customers. These programs include E.piphany's own market
research, product and strategy updates with industry analysts, public relations
activities, direct mail programs, telemarketing and telesales, seminars, trade
shows, reseller programs, speaking engagements and Web site marketing.
E.piphany's marketing organization also produces marketing materials in support
of sales to prospective customers that include brochures, data sheets, white
papers, presentations and demonstrations.

INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS

     E.piphany's future success depends in part on legal protection of
E.piphany's technology. To protect its technology, E.piphany relies on a
combination of the following among others:

     - patent laws,

     - copyright laws,

     - trademark laws,

     - trade secret laws, and

     - employee and third-party nondisclosure agreements and confidentiality
       procedures.

     E.piphany holds one patent and has applied for seven other patents on
E.piphany's technology in the United States and made one international
application. E.piphany has also applied for additional trademarks. E.piphany's
pending patent and trademark applications may not be allowed. Even if they are
allowed, these patents may not provide E.piphany a competitive advantage.
Competitors may successfully challenge the validity and scope of E.piphany's
patents and trademarks.

     E.piphany's end-user licenses are designed to prohibit unauthorized use,
copying and disclosure of E.piphany's software and technology. However, these
provisions may be unenforceable under the laws of some jurisdictions and foreign
countries. Unauthorized third parties may be able to copy some portions of
E.piphany's products or reverse engineer or obtain and use information and
technology that E.piphany regards as proprietary. Third parties could also
independently develop competing technology or design around E.piphany's
technology. If E.piphany is unable to successfully detect infringement and
enforce its rights to its technology, E.piphany may lose competitive position in
the market. E.piphany cannot assure you that its means of protecting its
proprietary rights in the United States or abroad will be adequate or that
competing companies will not independently develop similar technology. In
addition, some of E.piphany's licensed users may allow additional unauthorized
users to use E.piphany's software, and if E.piphany does not detect such use it
could lose potential license fees.

                                       96
<PAGE>   103

     From time to time, E.piphany may encounter disputes over rights and
obligations concerning intellectual property. E.piphany believes that its
products do not infringe the intellectual property rights of third parties.
However, E.piphany cannot assure you that E.piphany will prevail in all
intellectual property disputes. E.piphany has not conducted a search for
existing patents and other intellectual property registrations, and E.piphany
cannot assure you that its products do not infringe upon issued patents. In
addition, because patent applications in the United States are not publicly
disclosed until the patent is issued, applications may have been filed which
would relate to E.piphany's products.

     E.piphany indemnifies some of its customers against claims that its
products infringe upon the intellectual property rights of others. E.piphany
could incur substantial costs in defending its company and its customers against
infringement claims. In the event of a claim of infringement, E.piphany or its
customers may be required to obtain one or more licenses from third parties.
E.piphany cannot assure you that such licenses could be obtained from third
parties at a reasonable cost, or at all. Defense of any lawsuit or failure to
obtain any such required license would have a material adverse effect on
E.piphany's business.

COMPETITION

     The market for E.piphany's products is intensely competitive, subject to
rapid change and significantly affected by new product introductions and other
market activities of industry participants. E.piphany's integrated software
competes against various vendors' software tools designed to accomplish specific
elements of a complete process, including extracting data, storing and managing
data, analyzing data, or managing marketing campaigns. E.piphany's competitors
include companies that sell:

     - data management and data analysis software tools, such as Brio
       Technology, Broadbase, Business Objects, Informatica, Microstrategy and
       Sagent Technology,

     - enterprise application software, such as Oracle, PeopleSoft, SAP and
       Siebel Systems,

     - marketing campaign management software tools, such as Exchange
       Applications, Prime Response, and Recognition Systems,

     - software that recommends products to customers in real-time based on
       simple analytics rules such as Net Perceptions, and

     - electronic customer relations management software, such as Kana
       Communications (Silknet Software), eGain, Primus Knowledge Solutions,
       Nortel (Clarify), PeopleSoft (Vantive), and Siebel Systems (Scopus).

     Many of E.piphany's competitors have longer operating histories,
significantly greater financial, technical, marketing, or other resources, or
greater name recognition than E.piphany does. E.piphany's competitors may be
able to respond more quickly to new or emerging technologies and changes in
customer requirements. Competition could seriously harm E.piphany's ability to
sell additional software, maintenance renewals, and services on terms favorable
to E.piphany. Competitive pressures could reduce E.piphany's market share or
require E.piphany to reduce the price of its products and services, any of which
could materially and adversely affect E.piphany's business, financial condition
and operating results.

     E.piphany competes on the basis of certain factors, including:

     - product performance,

     - product features,

     - user scalability,

                                       97
<PAGE>   104

     - open architecture,

     - ease of use,

     - product reliability,

     - analytic capabilities,

     - time to market,

     - customer support, and

     - product pricing.

     E.piphany believes that it presently competes favorably with respect to
each of these factors. However, the markets for E.piphany's products are still
rapidly evolving, and E.piphany may not be able to compete successfully against
current and potential competitors.

EMPLOYEES

     As of March 31, 2000, E.piphany has 333 full-time employees. Of these
employees, 86 are engaged in research and development, 117 are engaged in sales
and marketing, 93 are engaged in professional services and 37 are engaged in
finance and administration.

     None of E.piphany's employees is represented by a labor union or a
collective bargaining agreement. E.piphany has not experienced any work
stoppages and considers its relations with its employees to be good.

FACILITIES

     E.piphany currently leases approximately 32,500 square feet of office space
for E.piphany's headquarters in one building in San Mateo, California. E.piphany
also leases approximately 35,500 square feet of additional office space in two
additional buildings in San Mateo, California. E.piphany also leases sales
offices near Atlanta, Boston, Chicago, Detroit, Dallas, London, Los Angeles,
Minneapolis, Phoenix, St. Louis and Stamford, Connecticut. E.piphany believes
that its facilities are adequate for its current needs. E.piphany may need to
locate additional space to meet its needs in the future.

LEGAL PROCEEDINGS

     From time to time, E.piphany may become involved in litigation relating to
claims arising from its ordinary course of business. E.piphany believes that
there are no claims or actions pending or threatened against E.piphany, the
ultimate disposition of which would have a material adverse effect on E.piphany.

                 E.PIPHANY MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion of E.piphany's financial condition and results of
operations should be read in conjunction with E.piphany's financial statements
and related notes. This discussion contains forward-looking statements that
involve risks and uncertainties. Forward-looking statements include statements
regarding the extent and timing of future revenues and expenses and customer
demand, statements regarding the deployment of E.piphany's products, and
statements regarding E.piphany's reliance on third parties. All forward-looking
statements included in this document are based on information available to
E.piphany as of the date hereof, and E.piphany assumes no obligation to update
any such forward-looking statement. E.piphany's actual results could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including but not limited to, those discussed in the
section entitled "Risk Factors" in this proxy statement/prospectus.

OVERVIEW

     The E.piphany E.4 System is an integrated set of software solutions that
provide capabilities for analysis of customer data and managing distributed
database marketing. Companies can implement the E.piphany E.4 System to collect
and analyze data from their existing software systems, and from third party data
providers, to profile their customers' characteristics and preferences. Business
users within these companies can then act on this information by using the
E.piphany E.4 System to design and execute marketing campaigns as well as
personalize products, services and related interactions.

     E.piphany was founded in November 1996. From E.piphany's founding through
the end of 1997, E.piphany primarily engaged in research activities, developing
products and building business infrastructure. E.piphany began shipping its
first software product and first generated revenues from software license fees,
implementation and consulting fees, and maintenance fees in early 1998. During
1998, E.piphany introduced several other software products, and in June 1999,
E.piphany began shipping its E.piphany E.4 System software solutions. Although
E.piphany's revenues consistently increased from quarter to quarter during 1998
and 1999, E.piphany incurred significant costs to develop its technology and
products, to continue the recruitment of research and development personnel, to
build a direct sales force and a professional services organization, and to
expand its general and administrative infrastructure. E.piphany's total
headcount has increased from 69 employees at December 31, 1998 to 333 employees
at March 31, 2000.

ACQUISITIONS

THE OCTANE ACQUISITION

     On March 14, 2000, E.piphany entered into a definitive agreement to acquire
Octane Software, Inc. E.piphany expects to complete the acquisition during the
quarter ending June 30, 2000. Octane is a next-generation provider of
multi-channel customer interaction applications and infrastructure software for
sales, service and support. Under the terms of the agreement, E.piphany will
issue up to approximately 12.8 million shares of its common stock in return for
all outstanding shares of Octane capital stock and options, warrants and other
rights to purchase Octane capital stock. The acquisition is subject to customary
closing conditions, including regulatory approval and the approval of
E.piphany's stockholders and Octane's shareholders.

     Octane began offering its Internet relationship management applications in
the second quarter of 1999, and began generating revenue from its Internet
relationship management applications in its fiscal quarter ended December 31,
1999. Octane has also experienced significant increases in headcount during 1999
and the first quarter of 2000. As of March 31, 2000, Octane had 263 employees.
Octane has incurred substantial costs to develop its products, and to recruit
and train personnel for its engineering, sales and marketing services
organizations.

                                       101
<PAGE>   108

     E.piphany expects that the combination of the companies will result in
significant increases in all expense categories. As of March 31, 2000, Octane
had 60 employees engaged in the delivery of services, 85 employees engaged in
research and development, 84 employees engaged in sales and marketing and 34
employees engaged in general and administrative activities. E.piphany expects
that operating expenses will increase in absolute dollars and may increase as a
percentage of revenue as a result of the acquisition.

     E.piphany expects that it will continue to add employees across all
departments to invest in the development of technology, to continue to build a
direct sales force and professional services organization and to expand
E.piphany's general and administrative infrastructure following the acquisition.
This expansion places significant demands on E.piphany's management and
operational resources. To manage rapid growth and increased demand, E.piphany
must continue to invest in and implement additional operational systems,
procedures and controls.

     E.piphany will account for the acquisition under the purchase method of
accounting and expects to incur a write-off related to in-process research and
development of approximately $25 million in the quarter ending June 30, 2000
upon closing of the transaction, as the in-process technology acquired has not
reached technological feasibility and, in the opinion of management, has no
alternative future use. In addition to the in-process research and development
charge E.piphany will incur, E.piphany expects to allocate a portion of the
purchase price to intangible assets of approximately $2.7 billion which will be
amortized ratably over their estimated useful life of three years.

THE ILEVERAGE ACQUISITION

     On March 27, 2000, E.piphany entered into a definitive agreement to acquire
privately held iLeverage Corporation, a start-up company that is developing
marketing solutions for digital marketplaces, for 181,649 shares of E.piphany
common stock. The acquisition will be accounted for as a purchase and is subject
to customary closing conditions, including the approval of iLeverage
stockholders.

THE ECLASS DIRECT ACQUISITION

     On April 14, 2000, E.piphany entered into a definitive agreement to acquire
privately held eClass Direct, an application service provider of
permission-based e-mail marketing services, for approximately 750,000 shares of
E.piphany common stock. The acquisition will be accounted for as a purchase and
is subject to customary closing conditions, including the approval of eClass
Direct stockholders.

THE RIGHTPOINT ACQUISITION

     E.piphany acquired RightPoint Software, Inc. on January 4, 2000 in a merger
transaction. RightPoint develops and markets real time marketing software
solutions that enable companies to optimize and present marketing offers,
promotions, and communications while a customer is interacting with a web site,
call center agent or other point of customer interaction. In connection with
this transaction, E.piphany acquired all of the outstanding shares of capital
stock of RightPoint in exchange for approximately 3.1 million shares of
E.piphany's common stock. In addition, options and warrants of RightPoint were
converted into options and warrants to purchase approximately 530,000 shares of
E.piphany's common stock.

     RightPoint began offering its current real-time marketing applications in
April 1998. RightPoint began generating revenue from its real-time marketing
applications in its fiscal year ended June 30, 1998. RightPoint's revenues grew
from $806,000 in its fiscal 1998 to $3.5 million in its fiscal 1999. RightPoint
also experienced significant increases in headcount during this period.
RightPoint grew

                                       102
<PAGE>   109

from 34 employees on June 30, 1998 to 79 employees as of December 31, 1999.
RightPoint incurred substantial costs to develop its products, and to recruit
and train personnel for its engineering, sales and marketing services
organizations.

     E.piphany accounted for the acquisition under the purchase method of
accounting and incurred a write-off related to in-process research and
development of $22 million which was reflected in the results of operations for
the quarter ended March 31, 2000, as the in-process technology acquired had not
reached technological feasibility and, in the opinion of management, has no
alternative future use. In addition to the in-process research and development
charge E.piphany incurred, E.piphany recorded intangible assets of approximately
$479 million which are being amortized ratably over an estimated useful life of
three years.

SOURCE OF REVENUES AND REVENUE RECOGNITION POLICY

     E.piphany generates revenues principally from licensing its software
products directly to customers and providing related professional services
including implementation, consulting, support and training. Through March 31,
2000, substantially all of E.piphany's revenues have been derived from sales
within the United States through E.piphany's direct sales force. E.piphany's
license agreements generally provide that customers pay a software license fee
for one or more software solutions for a specified number of users. The amount
of the license fee varies based on which software solution is purchased, the
number of software solutions purchased and the number of users licensed.
Customers can subsequently pay additional license fees to allow additional users
to use previously purchased software solutions or to purchase additional
software solutions. Each software solution included in the E.piphany E.4 System
contains the same core technology, allowing for easy integration of additional
software solutions as they are purchased from E.piphany. Customers that purchase
software solutions receive the software on compact disc or via Internet
delivery.

     Customers generally require consulting and implementation services which
include evaluating their business needs, identifying the data sources necessary
to meet these needs and installing the software solution in a manner which
fulfills their needs. Customers have generally purchased these services directly
from E.piphany through E.piphany's internal professional services organization
on either a fixed fee or a time and expense basis. E.piphany has historically
supplemented the capacity of its internal professional services organization by
subcontracting some of these services to consulting organizations, especially to
those organizations with which E.piphany has relationships such as KPMG,
Cambridge Technology Partners and Ernst & Young. However, E.piphany intends to
increasingly encourage customers to purchase services directly from these
consulting organizations. E.piphany believes that this would increase the number
of consultants which can provide consulting and implementation services related
to E.piphany's software products and that it would increase E.piphany's overall
gross margins by increasing E.piphany's percentage of license revenue, which has
substantially higher gross margins than services revenue, as a percentage of
total revenue. E.piphany also believes that it will encourage these consulting
organizations to generate sales leads within their customer base.

     Customers also generally purchase maintenance contracts which provide
software upgrades and technical support over a stated term, generally twelve
months. Revenue on software upgrades and technical support is recognized ratably
over the term of the maintenance contract.

                                       103
<PAGE>   110

     E.piphany recognizes product license revenues in accordance with the
provisions of American Institute of Certified Public Accounts (AICPA) Statement
of Position (SOP) 97-2, "Software Revenue Recognition." Pursuant to the
requirements of SOP 97-2, E.piphany recognizes product license revenues when all
of the following conditions are met:

     - E.piphany has signed a noncancellable agreement with the customer,

     - E.piphany has delivered the software product to the customer,

     - the amount of fees to be paid by the customer is fixed or determinable,
       and

     - E.piphany believes that collection of these fees is probable.

     To date, when E.piphany manages the implementation process for its
customers, the implementation services have been considered essential to the
functionality of the software products. Accordingly, both the product license
revenues and services revenues are recognized in accordance with the provisions
of SOP 81-1, "Accounting for Performance of Construction Type and Certain
Production Type Contracts." Prior to 1999, E.piphany recognized substantially
all of its revenues using the completed contract method as estimates of costs
and efforts necessary to complete the implementation were generally not reliable
given E.piphany's lack of history with implementing its products. In 2000 and
future periods, E.piphany expects to recognize most of its revenues using the
percentage of completion method, and therefore both product license and services
revenues are recognized as work progresses. While E.piphany's software solutions
can generally be implemented in less than 16 weeks, implementation can take
longer depending on the solution which has been licensed, the number of software
solutions licensed, the complexity of the customer's information technology
environment and the resources directed by customers to the implementation
projects. To date, E.piphany has managed the implementation of E.piphany's
solutions for the substantial majority of its customers. When E.piphany
subcontracts services to consulting organizations, E.piphany is responsible for
managing the implementation. To the extent that customers contract directly with
consulting organizations to provide implementation services, E.piphany does not
manage the implementation, and license revenues are recognized when the relevant
conditions of SOP 97-2 are met. Some of E.piphany's contracts provide for the
delivery of unspecified future products over a period of time. Accordingly,
payments received from E.piphany's customers upon the signing of these
agreements are deferred and the revenues are recognized ratably over the
contract period. Revenue allocated to training and other services is recognized
as the services are performed.

COST OF REVENUES AND OPERATING EXPENSES

     E.piphany's cost of license revenues primarily consists of license fees due
to third parties for integrated technology. E.piphany's cost of services
revenues include salaries and related expenses for E.piphany's implementation,
consulting support and training organizations, costs of subcontracting to
consulting organizations to provide consulting services to customers and an
allocation of facilities, communications and depreciation expenses. E.piphany's
operating expenses are classified into three general categories: sales and
marketing, research and development, and general and administrative. E.piphany
classifies all charges to these operating expense categories based on the nature
of the expenditures. E.piphany allocates the costs for overhead and facilities
to each of the functional areas that use the overhead and facilities services
based on their headcount. These allocated charges include facility rent for
corporate offices, communication charges and depreciation expenses for office
furniture and equipment.

     Software development costs incurred prior to the establishment of
technological feasibility are included in research and development costs as
incurred. Since license revenues from E.piphany's software solutions are not
recognized until after technological feasibility has been established, software

                                       104
<PAGE>   111

development costs are not generally expensed in the same period in which license
revenues for the developed products are recognized.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2000 AND 1999

     E.piphany's results of operations for the three months ended March 31, 2000
include the results of RightPoint, which was acquired on January 4, 2000.

REVENUES

     Total revenues increased to $14.4 million for the three months ended March
31, 2000, from $1.9 million for the three months ended March 31, 1999. For the
three months ended March 31, 2000, there were no customers that made up more
than 10% of revenue. For the three months ended March 31, 1999, KPMG, FileNET,
Pivotal, and Hilton accounted for 22%, 13%, 10%, and 10% of total revenues,
respectively.

     Product license revenues increased to $8.3 million, or 57% of total
revenue, for the three months ended March 31, 2000 from $1.1 million, or 60% of
total revenue, for the three months ended March 31, 1999. The increase in dollar
amount of product license revenues was due to both an increase in the number of
licenses sold and the average size of the licenses, and resulted primarily from
the growth of E.piphany's direct sales force and the introduction and shipment
of new products.

     Services revenues increased to $6.1 million, or 43% of total revenues, for
the three months ended March 31, 2000 from $0.8 million, or 40% of revenues, for
the three months ended March 31, 1999. The increase in dollar amount of service
revenues was primarily attributable to increased implementation and consulting
services performed in connection with increased license sales and to maintenance
contracts sold to E.piphany's new customers.

     Services revenues as a percentage of total revenues has varied
significantly from quarter to quarter due to E.piphany's relatively early stage
of development. The relative amount of services revenues as compared to license
revenues has varied based on the volume of license fees for software solutions
compared to the volume of license fees for additional users, which generally do
not require services. In addition, the amount of services E.piphany provides for
a software solution can vary greatly depending on the solution which has been
licensed, the complexity of the customers' information technology environment,
the resources directed by customers to their implementation projects, the number
of users licensed and the extent to which consulting organizations provide
services directly to customers. Services revenues have substantially lower
margins relative to product license revenues. To the extent that services
revenues become a greater percentage of our total revenues and services margins
do not increase, E.piphany's overall gross margins will decline.

     This is especially true when E.piphany is required to subcontract with
consulting organizations to supplement its internal professional services
organization. It generally costs E.piphany more to subcontract with consulting
organizations to provide these services than to provide these services itself.
To offset the effect that providing services itself or through subcontractors
has on E.piphany's gross margins, E.piphany intends to further encourage
customers to contract directly with consulting organizations for implementation
and consulting services. Encouraging direct contracts between E.piphany's
customers and consulting organizations may also increase the overall amount of
services available to customers and generate sales leads. E.piphany does not
receive any services revenues when customers contract directly with consulting
organizations for implementation and consulting services.

COST OF REVENUES

     Total cost of revenues increased to $6.1 million for the three months ended
March 31, 2000 from $0.8 million for the three months ended March 31, 1999. Cost
of product license revenues consists primarily of license fees paid to third
parties under technology license arrangements and have not been

                                       106
<PAGE>   113

significant to date. Cost of services revenues consists primarily of the costs
of consulting and customer service and support. Cost of services revenues
increased to $6.0 million, or 98% of services revenues, for the three months
ended March 31, 2000 from $0.8 million, or 109% of services revenues, for the
three months ended March 31, 1999. The increase in cost of services revenues in
absolute dollars resulted primarily from the hiring of additional employees and
the subcontracting of consulting services to consulting organizations to support
increased customer demand for consulting services. Cost of services revenues has
almost exceeded service revenues, and during the three months ended March 31,
1999 exceeded services revenues, due to the rapid growth of E.piphany's services
organization from 5 employees at September 30, 1998 to 93 employees at March 31,
2000 and E.piphany's investment in experienced management in anticipation of
future revenue growth.

OPERATING EXPENSES

Research and Development

     Research and development expenses consist primarily of personnel and
related costs associated with E.piphany's product development efforts. Research
and development expenses increased to $3.8 million for the three months ended
March 31, 2000 from $1.3 million for the three months ended March 31, 1999. The
increase in absolute dollars was primarily due to an increase in the number of
employees engaged in research and development from 22 employees as of March 31,
1999 to 86 employees as of March 31, 2000. Research and development expenses as
a percentage of total revenues decreased from 68% for the three months ended
March 31, 1999 to 26% for the three months ended March 31, 2000. Research and
development expenses as a percentage of total revenues decreased primarily due
to growth in E.piphany's revenues. E.piphany believes that investments in
product development are essential to its future success and expects that the
absolute dollar amount of research and development expenses will increase in
future periods.

Sales and Marketing

     Sales and marketing expenses consist primarily of employee salaries,
benefits and commissions, and the costs of trade shows, seminars, promotional
materials and other sales and marketing programs. Sales and marketing expenses
increased to $11.2 million for the three months ended March 31, 2000 from $2.8
million for the three months ended March 31, 1999. Sales and marketing expenses
as a percentage of total revenues decreased from 146% for the three months ended
March 31, 1999 to 78% for the three months ended March 31, 2000. The increase in
sales and marketing expenses in absolute dollars was primarily attributable to
an increase in the number of direct sales, pre-sales support and marketing
employees from 27 as of March 31, 1999 to 117 as of March 31, 2000. E.piphany
expects that the absolute dollar amount of sales and marketing expenses will
continue to increase due to the planned growth of its sales force, including the
establishment of sales offices in additional domestic and international
locations including Europe and Asia, and due to expected additional increases in
advertising and marketing programs and other promotional activities.

General and Administrative

     General and administrative expenses consist primarily of employee salaries
and related expenses for executive, finance and administrative personnel.
General and administrative expenses increased to $2.3 million for the three
months ended March 31, 1999 from $0.5 million for the three months ended March
31, 2000. The increase in general and administrative expenses in absolute
dollars was primarily attributable to an increase in the number of executive,
finance and administrative employees from 7 as of March 31, 1999 to 37 as of
March 31, 2000. E.piphany expects general and administrative expenses to
increase in absolute dollars in future periods.

Amortization of Goodwill and Purchased Intangibles

     Goodwill represents the purchase price of RightPoint in excess of
identified tangible and intangible assets. In January 2000, E.piphany recorded
$479.3 million of goodwill, which is being amortized on a straight-line basis
over three years. E.piphany recorded amortization expense of $39.9 million for
the three months ended March 31, 2000.

In-Process Research and Development Charge

     In connection with the RightPoint acquisition, E.piphany expensed $22.0
million of acquired in-process research and development which, in the opinion of
management, had not reached technological feasibility and had no alternative
future use.

     E.piphany allocated values to in-process research and development based on
an assessment of the R&D projects. The value assigned to these assets was
limited to significant research projects for which technological feasibility had
not been established, including development, engineering and testing activities
associated with the introduction of RightPoint's next-generation technologies.

     The value assigned to purchased in-process technology was determined by
estimating the costs to develop the purchased in-process technology into
commercially viable products, estimating the resulting net cash flows from the
projects and discounting the net cash flows to their present value. The revenue
projection used to value the in-process research and development was based on
estimates of relevant market sizes and growth factors, expected trends in
technology, and the nature and expected timing of new product introductions by
RightPoint and its competitors.

     The nature of the efforts to develop the acquired in-process technology
into commercially viable products and services principally related to the
completion of certain planning, designing, coding, prototyping, and testing
activities that were necessary to establish that the developmental RightPoint
technologies met their design specifications including functional, technical,
and economic performance requirements. Anticipated completion dates ranged from
3 to 11 months, at which times RightPoint expected to begin selling the
developed products. Development costs to complete the R&D were estimated at
approximately $6.0 million.

     RightPoint's primary in-process R&D projects involved the development of
additional features and functionality to make the RealTime product suite a
complete e-marketing solution rather than a component technology. The estimated
revenues for the in-process projects were expected to peak within four years of
introduction and then decline as other new products and technologies are
expected to enter the market.

     Operating expenses were estimated based on historical results and
management's estimates regarding anticipated profit margin improvements. Due to
purchasing power increases and general economics of scale, estimated operating
expenses as a percentage of revenues were expected to decrease after the
acquisition.

     The rates utilized to discount the net cash flows to their present value
were based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the projected growth, profitability and
developmental projects, a discount rate of 25 percent was appropriate for the
in-process R&D, and a discount rate of 20 percent was appropriate for the
existing products and technology. These discount rates were commensurate with
RightPoint's stage of development and the uncertainties in the economic
estimates described above.

     The estimates used by E.piphany in valuing in-process research and
development were based upon assumptions E.piphany believes to be reasonable but
which are inherently uncertain and unpredictable. E.piphany's assumptions may be
incomplete or inaccurate, and no assurance can be given that unanticipated
events and circumstances will not occur. Accordingly, actual results may vary

                                       108
<PAGE>   115

from the projected results. Any such variance may result in a material adverse
effect on the financial condition and results of operations of E.piphany.

Stock-Based Compensation

     Stock-based compensation consists of amortization of deferred compensation
in connection with stock option grants and sales of stock to employees at
exercise or sales prices below the deemed fair market value of Epiphany's common
stock and compensation related to equity instruments issued to non-employees for
services rendered. E.piphany has recorded aggregate deferred compensation of
$5.9 million related to stock-based compensation to employees. This amount is
being amortized over the respective vesting periods of these equity instruments
in a manner consistent with Financial Accounting Standards Board Interpretation
No. 28. Total stock-based compensation was $477,000 for the three months ended
March 31, 2000. E.piphany expects amortization of approximately $1,023,000 in
the last three quarters of 2000 and $781,000, $309,000, and $25,000 for the
years ended December 31, 2001, 2002, and the first half of 2003, respectively.
See Note 6 to E.piphany's Notes to Financial Statements for further discussion
regarding the accounting treatment for stock-based compensation.

INTEREST INCOME, NET

     The increase in interest income, net of interest expense, for the three
months ended March 31, 2000 when compared to the same period in the prior year
was due to increased cash balances as a result of the completion of E.piphany's
initial public offering in September 1999 and its secondary offering in January
2000.

YEARS ENDED DECEMBER 31, 1999 AND 1998

REVENUES

     Total revenues increased to $19.2 million for the year ended December 31,
1999, from $3.4 million for the year ended December 31, 1998. This rapid growth
in revenues reflects E.piphany's relatively early stage of development, and
E.piphany does not expect revenues to increase at the same rate in the future.
For the year ended December 31, 1999, Sallie Mae accounted for 11% of
E.piphany's total revenues, and for the year ended December 31, 1998, Autodesk,
Charles Schwab, Hewlett-Packard, KPMG, and Macromedia accounted for 30%, 17%,
16%, 11%, and 11% of total revenues, respectively.

     Product license revenues increased to $10.2 million, or 53% of total
revenue, for the year ended December 31, 1999 from $2.2 million, or 66% of total
revenue, for the year ended December 31, 1998. The increase in dollar amount of
product license revenues was due to both an increase in the number of licenses
sold and the average size of the licenses, and resulted primarily from the
growth of E.piphany's direct sales force and the introduction and shipment of
new products.

     Services revenues increased to $9.0 million, or 47% of total revenues, for
the year ended December 31, 1999 from $1.2 million, or 34% of revenues, for the
year ended December 31, 1998. The increase in dollar amount of service revenues
was primarily attributable to increased implementation and consulting services
performed in connection with increased license sales and to maintenance
contracts sold to E.piphany's new customers.

COST OF REVENUES

     Total cost of revenues increased to $9.3 million for the year ended
December 31, 1999 from $1.4 million for the year ended December 31, 1998. Cost
of services revenues increased to $9.2 million, or 102% of services revenues,
for the year ended December 31, 1999 from $1.4 million,

                                       109
<PAGE>   116

or 120% of services revenues, for the year ended December 31, 1998. The increase
in cost of services revenues in absolute dollars resulted primarily from the
hiring of additional employees and the subcontracting of consulting services to
consulting organizations to support increased customer demand for consulting
services. Cost of services revenues has exceeded services revenues due to the
rapid growth of E.piphany's services organization from 11 employees at December
31, 1998 to 53 employees at December 31, 1999 and E.piphany's investment in
experienced management in anticipation of future revenue growth.

OPERATING EXPENSES

Research and Development

     Research and development expenses increased to $7.1 million for the year
ended December 31, 1999 from $3.8 million for the year ended December 31, 1998.
The increase in absolute dollars was primarily due to an increase in the number
of employees engaged in research and development from 23 employees as of
December 31, 1998 to 55 employees as of December 31, 1999. Research and
development expenses as a percentage of total revenues decreased from 112% for
the year ended December 31, 1998 to 37% for the year ended December 31, 1999.
Research and development expenses as a percentage of total revenues decreased
primarily due to growth in E.piphany's revenues. E.piphany believes that
investments in product development are essential to E.piphany's future success
and expects that the absolute dollar amount of research and development expenses
will increase in future periods.

Sales and Marketing

     Sales and marketing expenses increased to $18.7 million for the year ended
December 31, 1999 from $6.5 million for the year ended December 31, 1998. Sales
and marketing expenses as a percentage of total revenues decreased from 193% for
the year ended December 31, 1998 to 98% for the year ended December 31, 1999.
The increase in sales and marketing expenses in absolute dollars was primarily
attributable to an increase in the number of direct sales, pre-sales support and
marketing employees from 30 as of December 31, 1998 to 70 as of December 31,
1999. E.piphany expects that the absolute dollar amount of sales and marketing
expenses will continue to increase due to the planned growth of E.piphany's
sales force, including the establishment of sales offices in additional domestic
and international locations including Europe and Asia, and due to expected
additional increases in advertising and marketing programs and other promotional
activities.

General and Administrative

     General and administrative expenses increased to $4.6 million for the year
ended December 31, 1999 from $1.5 million for the year ended December 31, 1998.
The increase in general and administrative expenses in absolute dollars was
primarily attributable to an increase in the number of executive, finance and
administrative employees from 5 as of December 31, 1998 to 22 as of December 31,
1999. E.piphany expects general and administrative expenses to increase in
absolute dollars in future periods.

Stock-Based Compensation

     Total stock-based compensation was $2.9 million for the year ended December
31, 1999. E.piphany expects amortization of approximately $1,500,000, $781,000,
$309,000, and $25,000 in the years ended December 31, 2000, 2001, 2002, and the
first half of 2003, respectively. See Note 6 to E.piphany's Notes to Financial
Statements for further discussion regarding the accounting treatment for
stock-based compensation.

<PAGE>   117

INTEREST INCOME, NET

     Interest income, net of interest expense, for the year ended December 31,
1999 increased by $0.8 million compared to the same period in the prior year.
The increase was primarily attributable to interest income resulting from higher
average cash balances during the more recent period.

YEARS ENDED DECEMBER 31, 1998 AND 1997

REVENUES

     E.piphany's total revenues were $3.4 million in 1998 and were comprised of
the first commercial sales of software products and related services fees from
implementation, training and support. Product license revenues were $2.2 million
in 1998. Services revenues were $1.2 million in 1998. For 1998, product license
revenues and services revenues accounted for 66% and 34% of revenues,
respectively. E.piphany did not recognize any revenues in 1997.

     In 1998, Autodesk, Charles Schwab, Hewlett-Packard, KPMG and Macromedia,
accounted for 30%, 17%, 16%, 11% and 11% of total revenues, respectively.

COST OF REVENUES

     Cost of revenues was $1.4 million in 1998. Cost of services revenues as a
percentage of services revenues was 120%. Cost of services revenues in 1998
resulted primarily from the hiring of employees and, to a lesser extent, the
subcontracting of consulting organizations to support customer demand for
consulting and maintenance services. E.piphany did not have any revenues in 1997
and thus had no cost of revenues in 1997.

OPERATING EXPENSES

Research and Development

     Research and development expenses increased to $3.8 million, or 112% of
total revenues, in 1998 from $1.6 million in 1997. The increase in research and
development expenses was related primarily to an increase in the number of
employees engaged in research and development to support the development of new
products.

Sales and Marketing

     Sales and marketing expenses increased to $6.5 million, or 193% of total
revenues, in 1998 from $1.2 million in 1997. The increase in sales and marketing
expenses resulted primarily from building a direct sales force and investing in
sales and marketing infrastructure which included significant personnel-related
expenses, recruiting fees, travel expenses, and related facility and equipment
costs, as well as increased marketing activities, including trade shows, public
relations, direct mail campaigns and other promotional expenses.

General and Administrative

     General and administrative expenses increased to $1.5 million, or 45% of
total revenues, in 1998 from $0.4 million in 1997. The increase in dollar amount
of general and administrative expenses resulted primarily from the addition of
executive, finance and administrative personnel to support the growth of
E.piphany's business.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash used in operating activities totaled $4.2 million and $3.2 million
for the three months ended March 31, 2000 and 1999, respectively. Cash used in
operating activities for each period

                                       111
<PAGE>   118

resulted from net losses in those periods. For the period ended March 31, 2000,
cash used in operating activities also resulted from an increase in accounts
receivable and a decrease in accounts payable. These uses of cash were partially
offset by an increase in accrued liabilities. Net cash used in operating
activities totaled $17.8 million and $8.7 million for the years ended December
31, 1999 and 1998, respectively. Cash used in operating activities for each
period resulted primarily from net losses in those periods, and to a lesser
extent, increases in accounts receivable. These uses of cash were partially
offset by increases in accrued liabilities and deferred revenue.

     Net cash used in investing activities totaled $24.2 million and $0.5
million for the three months ended March 31, 2000 and 1999, respectively. The
increase resulted from purchases of short-term investments and to a lesser
extent, purchases of property and equipment. Net cash used in investing
activities totaled $25.9 million and $1.1 million for the years ended December
31, 1999 and 1998, respectively. The increase resulted primarily from the
purchase of short-term investments and to a lesser extent, purchases of
furniture and equipment, consisting largely of computer servers and
workstations.

     Net cash provided by financing activities totaled $348.7 million and $3.0
million for the three months ended March 31, 2000 and 1999, respectively. The
increase was due primarily to the receipt of proceeds from E.piphany's recently
completed secondary offering. Net cash provided by financing activities totaled
$88.2 million and $23.0 million for the years ended December 31, 1999 and 1998,
respectively. The increase was due primarily to the receipt of proceeds from
E.piphany's recently completed initial public offering.

     At March 31, 2000, E.piphany had $401.3 million in cash and cash
equivalents and $23.5 million in short-term investments. E.piphany has a $3.0
million term loan under a senior credit facility that is repayable ratably over
a 36-month period beginning March 1, 2000. The term loan bears variable interest
at the bank's prime rate plus 0.5%, currently 9.0%. As of December 31, 1999,
E.piphany had borrowed $3.0 million against this term loan. This loan is secured
by essentially all of E.piphany's assets and was paid in full during January
2000.

     On January 20, 2000, E.piphany completed a follow-on public offering.
E.piphany issued 1,993,864 shares of common stock in exchange for net proceeds
of approximately $338.6 million, after deduction of the underwriters' discount
and expenses. In connection with the follow-on offering on February 15, 2000,
the underwriters' exercised an option to purchase from E.piphany an additional
104,342 shares of common stock, resulting in additional net proceeds of
approximately $17.7 million, after the underwriters' discount and expenses. The
aggregate number of shares of E.piphany common stock issued in the follow-on
offering was 2,098,206, resulting in aggregate net proceeds of approximately
$365.4 million, after the underwriters' discount and expenses.

     In addition, E.piphany has a subordinated debt facility with Comdisco, Inc.
under which E.piphany is entitled to borrow up to $10.0 million, of which $5.0
million was outstanding as of December 31, 1999, over 42 months beginning June
1999 at a fixed interest rate of 10.0%. All borrowings under the subordinated
facility are secured by essentially all of E.piphany's assets after the rights
of senior creditors, and E.piphany cannot maintain more than $5.0 million of
senior debt without approval of the lender. This loan was paid in full during
January 2000. E.piphany also has a $2.0 million equipment lease line with
Comdisco. Under the equipment lease line, E.piphany is entitled to lease
equipment with payment terms extending over 42 months. The ability to lease new
equipment expires on May 31, 2000 and borrowings bear interest at 8.5% for the
first six months of the lease, and 8.0% thereafter. E.piphany is currently
considering whether to seek to extend this equipment lease line.

     As of March 31, 2000, E.piphany's principal sources of liquidity included
$401.3 million of cash and cash equivalents and $23.5 million in short-term
investments. E.piphany anticipates a substantial

                                       112
<PAGE>   119

increase in its capital expenditures consistent with anticipated growth in
operations, infrastructure and personnel. E.piphany believes that its current
cash and cash equivalents and short-term investments will be sufficient to meet
its anticipated liquidity needs for working capital and capital expenditures for
the foreseeable future. If E.piphany requires additional capital resources to
grow its business internally or to acquire complementary technologies and
businesses at any time in the future, E.piphany may seek to sell additional
equity or debt securities or secure an additional bank line of credit. The sale
of additional equity or convertible debt securities could result in additional
dilution to E.piphany's stockholders. E.piphany cannot assure you that any
financing arrangements will be available in amounts or on terms acceptable to it
in the future.

MARKET RISK

     The following discusses E.piphany's exposure to market risk related to
changes in interest rates, equity prices and foreign currency exchange rates.
This discussion contains forward-looking statements that are subject to risks
and uncertainties. Actual results could vary materially as a result of a number
of factors including those set forth in the risk factors section of this
prospectus.

Foreign Currency Exchange Rate Risk

     To date, all of E.piphany's recognized revenues have been denominated in
U.S. dollars and primarily from customers in the United States, and E.piphany's
exposure to foreign currency exchange rate changes has been immaterial.
E.piphany expects, however, that future product license and services revenues
may also be derived from international markets and may be denominated in the
currency of the applicable market. As a result, E.piphany's operating results
may become subject to significant fluctuations based upon changes in the
exchange rates of certain currencies in relation to the U.S. dollar.
Furthermore, to the extent that E.piphany engages in international sales
denominated in U.S. dollars, an increase in the value of the U.S. dollar
relative to foreign currencies could make E.piphany's products less competitive
in international markets. Although E.piphany will continue to monitor its
exposure to currency fluctuations, and, when appropriate, may use financial
hedging techniques in the future to minimize the effect of these fluctuations,
E.piphany cannot assure you that exchange rate fluctuations will not adversely
affect its financial results in the future.

Interest Rate Risk

     As of March 31, 2000, E.piphany had cash and cash equivalents of $401.3
million which consist of cash and highly liquid short-term investments. Declines
of interest rates over time will reduce E.piphany's interest income from its
short-term investments. Based upon E.piphany's balance of cash and cash
equivalents, a decrease in interest rates of 0.5% would cause a corresponding
decrease in E.piphany's annual interest income by approximately $2.0 million. As
of March 31, 2000, E.piphany did not have any short-term or long term debt
outstanding.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which requires companies to
record derivative financial instruments on their balance sheets as assets or
liabilities, measured at fair value. Gains or losses resulting from changes in
the values of those derivatives would be accounted for depending on the use of
the derivative and whether it qualifies for hedge accounting. The key criterion
for hedge accounting is that the hedging relationship must be highly effective
in achieving offsetting changes in fair value or cash flows. In June 1999, the
FASB issued SFAS No. 137, "Accounting For Derivative Instruments and Hedging
Activities -- Deferral of the Effective Date of FASB Statement No. 133," which
amends SFAS No. 133 to be effective for all fiscal quarters or all fiscal years
beginning after June 15, 2000, or

                                       113
<PAGE>   120

January 1, 2001 for E.piphany. E.piphany believes that this statement will not
have a material impact on the financial condition or results of E.piphany's
operations.

     In December 1998, the AICPA issued Statement of Position (SOP) 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions." SOP 98-9 amends SOP 97-2 and SOP 98-4 by extending the deferral
of the application of some provisions of SOP 97-2 amended by SOP 98-4 through
fiscal years beginning on or before March 15, 1999. All other provisions of SOP
98-9 are effective for transactions entered into in fiscal years beginning after
March 15, 1999. E.piphany does not anticipate that this statement will have a
material adverse impact on E.piphany's statement of operations.

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements." SAB 101 provides guidance on applying generally accepted accounting
principles to revenue issues in financial statements. E.piphany will adopt SAB
101 as required in the second quarter of 2000. E.piphany does not expect the
adoption of SAB 101 to have a material impact on its consolidated results of
operations and financial position.

CLASSIFIED BOARD

     E.piphany's certificate of incorporation provides for a classified board of
directors consisting of three classes of directors, each serving staggered
three-year terms. As a result, a portion of E.piphany's board of directors will
be elected each year. To implement the classified structure, prior to the
consummation of E.piphany's initial public offering, two of the nominees to the
board were elected to one-year terms, two were elected to two-year terms and two
were elected to three-year terms. Thereafter, directors will be elected for
three-year terms. Sam H. Lee and Roger S. Siboni were designated Class I
directors whose term expires at the 2000 annual meeting of stockholders. Douglas
J. Mackenzie and Gayle Crowell were designated Class II directors whose term
expires at the 2001 annual meeting of stockholders. Paul M. Hazen and Robert L.
Joss were designated Class III directors whose term expires at the 2002 annual
meeting of stockholders. For more information on the classified board, see the
section entitled "Description of Capital Stock -- Anti-takeover Effects of our
Certificate and Bylaws and Delaware Law."

     Executive officers are appointed by the board of directors on an annual
basis and serve until their successors have been duly elected and qualified.
There are no family relationships among any of E.piphany's directors, officers
or key employees.

BOARD COMMITTEES

     E.piphany established an Audit Committee in June 1999. The Audit Committee
of the Board of Directors currently consists of Messrs. Lee and Hazen. The Audit
Committee has met once in 2000, but did not meet in 1999. The Audit Committee
reviews the internal accounting procedures of E.piphany and consults with and
reviews the services provided by E.piphany's independent accountants.

     E.piphany established the Compensation Committee in June 1999. The
Compensation Committee of the Board of Directors currently consists of Messrs.
Mackenzie and Joss. The Compensation Committee held two meetings during fiscal
1999 and has held two meetings thus far in fiscal 2000. The Compensation
Committee reviews and recommends to the Board of Directors the compensation and
benefits of employees of E.piphany.

     The board of directors selects the directors who will serve as members of
these committees and may reduce or enlarge the size of the committees or change
the scope of their responsibilities. The board has no current plans to take any
of these actions. The rules of The Nasdaq Stock Market's National Market, on
which E.piphany's common stock is listed, require E.piphany to maintain an audit
committee consisting of at least two directors who are not employees of
E.piphany.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Prior to establishing the compensation committee, the board of directors as
a whole performed the functions delegated to the compensation committee. No
member of the board of directors or the compensation committee serves as a
member of the board of directors or compensation committee of any entity that
has one or more executive officers serving as a member of E.piphany's board of
directors or compensation committee.

DIRECTOR COMPENSATION

     Directors do not currently receive any cash compensation from E.piphany for
their service as members of the board of directors. Under E.piphany's 1999 stock
plan, outside directors are granted an option to purchase 25,000 shares of
E.piphany's common stock upon appointment to E.piphany's board of directors. In
addition, an option to purchase up to 12,500 shares of common stock is granted
to each outside director at the start of each of the second and third years of
his service at the then fair market value of E.piphany's common stock at that
time. During 1999, the board of directors granted options to purchase 25,000
shares to each of Robert L. Joss and Paul M. Hazen at an exercise price of $6.00
per share under E.piphany's 1997 stock plan. Following E.piphany's initial
public offering, E.piphany ceased making grants under its 1997 stock plan. See
the section entitled "-- Incentive Stock Plans."

(1) Messrs. Fernandez and Leach joined E.piphany in 1999.

     The other compensation paid to Mr. Siboni in 1998 represents amounts loaned
to Mr. Siboni in connection with his relocation to E.piphany in 1998, plus
accrued interest through December 31, 1998. The other compensation paid to Mr.
Siboni in 1999 represents accrued interest on Mr. Siboni's relocation loan from
January 1, 1999 to March 31, 1999. As provided in Mr. Siboni's employment
agreement, these amounts were forgiven by E.piphany on March 31, 1999.

OPTION GRANTS IN LAST FISCAL YEAR

     The following table sets forth information with respect to stock options
granted to each of the named executive officers in the fiscal year ended
December 31, 1999, including the potential realizable value over the ten-year
term of the options, based on assumed rates of stock appreciation of 0%, 5% and
10%, compounded annually. These assumed rates of appreciation comply with the
rules of the Securities and Exchange Commission and do not represent E.piphany's
estimate of future stock price. Actual gains, if any, on stock option exercises
will be dependent on the future performance of E.piphany's common stock.

     In the fiscal year ended December 31, 1999, E.piphany granted options to
purchase up to an aggregate of 3,436,078 shares to employees, directors and
consultants. All options were granted under E.piphany's 1997 stock option plan
and E.piphany's 1999 stock plan at exercise prices at or above the fair market
value of E.piphany's common stock on the date of grant, as determined in good
faith by

                                       118
<PAGE>   125

the board of directors. All options have a term of ten years. Optionees may pay
the exercise price by cash, check, cancellation of any outstanding indebtedness
of the option holder to us or delivery of already-owned shares of E.piphany's
common stock. All options listed below are immediately exercisable upon grant;
however, any unvested shares are subject to repurchase by E.piphany at their
cost if the optionee's service with Octane terminates. All option shares listed
in the table below vest over four years, with 25% of the option shares vesting
one year after the option grant date, and the remaining option shares vesting
ratably each month thereafter.

AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES

     The following table describes for the named executive officers their option
exercises for the fiscal year ended December 31, 1999, and exercisable and
unexercisable options held by them as of December 31, 1999.

     The "Value of Unexercised In-the-Money Options at December 31, 1999" is
based on a value of $223.125 per share, the closing price of E.piphany's common
stock on the Nasdaq Stock Market's National Market as of December 31, 1999, less
the per share exercise price, multiplied by the number of shares issued upon
exercise of the option. Options were granted under E.piphany's 1997 stock option
plan or 1999 stock option plan. All options listed below are immediately
exercisable; however, as a condition of exercise, the optionee must enter into a
restricted stock purchase agreement granting us the right to repurchase any
unvested portion of the shares issuable by such exercise at their cost in the
event of the optionee's termination of employment. The shares vest over four
years, with 25% of the shares vesting one year after the grant date and the
remaining shares vesting ratably each month thereafter.

INCENTIVE STOCK PLANS

1997 Stock Option Plan

     E.piphany's 1997 stock plan provides for the granting to employees of
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended, and for the

                                       119
<PAGE>   126

granting to employees and consultants of nonstatutory stock options and stock
purchase rights. As of March 31, 2000, options to purchase an aggregate of
2,824,214 shares of common stock were outstanding under E.piphany's 1997 stock
plan. E.piphany's board of directors determined that no further options will be
granted under the 1997 stock plan after the initial public offering. The 1997
stock plan provides that if E.piphany merges with or into another corporation,
or sell substantially all of E.piphany's assets, each outstanding option must be
assumed or substituted for by the successor corporation. If the successor
corporation refuses to assume or substitute for the E.piphany options, the
E.piphany options will terminate as of the closing of the merger or sale of
assets.

1999 Stock Plan

     E.piphany's 1999 stock plan was adopted by E.piphany's board of directors
in June 1999 and approved by the stockholders in July 1999. As of March 31,
2000, 845,200 options were outstanding under E.piphany's 1999 stock plan.
E.piphany's 1999 stock plan provides for the grant of incentive stock options to
employees, including officers and employee directors, and for the grant of
nonstatutory stock options and stock purchase rights to employees, directors and
consultants.

     A total of 4,696,577 shares of E.piphany's common stock are reserved for
issuance under the 1999 stock plan.

     Annual increases will be added to the 1999 stock plan equal to the lesser
of: (a) 2,500,000 shares, (b) 4% of all outstanding shares of E.piphany's common
stock or (c) a lesser amount determined by E.piphany's board of directors.

     Unless terminated sooner, E.piphany's 1999 stock plan will terminate on
September 21, 2009.

     The administrator of E.piphany's 1999 stock plan, which is currently
E.piphany's board of directors, has the power to determine among other things:

     - the terms of the options or stock purchase rights granted, including the
       exercise price of each option or stock purchase right,

     - the number of shares subject to each option or stock purchase right,

     - the exercisability of each option or stock purchase right, and

     - the form of consideration payable upon the exercise of each option or
       stock purchase right.

     In addition, the administrator has the authority to amend, suspend or
terminate E.piphany's 1999 stock plan, so long as the action does not affect any
shares of common stock previously issued and sold or any option previously
granted under E.piphany's 1999 stock plan. During any fiscal year, each optionee
may be granted options to purchase a maximum of 750,000 shares. In addition, in
connection with an optionee's initial employment with E.piphany, such optionee
may be granted an option covering an additional 750,000 shares.

     Options and stock purchase rights granted under E.piphany's 1999 stock plan
are generally not transferable by the optionee, and each option and stock
purchase right is exercisable during the lifetime of the optionee only by the
optionee. Options granted under E.piphany's 1999 stock plan must generally be
exercised within three months after the end of the optionee's status as an
employee, director or consultant of E.piphany, or within twelve months after
such optionee's termination by death or disability, but not later than the
expiration of the option's term.

     In the case of stock purchase rights, unless the administrator determines
otherwise, the restricted stock purchase agreement grants us a repurchase
option, exercisable for any unvested stock purchase rights, upon the voluntary
or involuntary termination of the purchaser's employment or consulting
relationship with E.piphany for any reason, including death or disability. The
purchase price for

                                       120
<PAGE>   127

shares repurchased pursuant to the restricted stock purchase agreement shall be
the original price paid by the purchaser and may be paid by cancellation of any
indebtedness of the purchaser to E.piphany. The repurchase option lapses at a
rate determined by the administrator.

     The exercise price of all incentive stock options granted under the 1999
stock plan must be at least equal to the fair market value of the common stock
on the date of grant. The exercise price of nonstatutory stock options and stock
purchase rights granted under the 1999 stock plan is determined by the
administrator, but with respect to nonstatutory stock options intended to
qualify as "performance-based compensation" within the meaning of Section 162(m)
of the Internal Revenue Code, the exercise price must be at least equal to the
fair market value of E.piphany's common stock on the date of grant. With respect
to any participant who owns stock having more than 10% of the voting power of
all classes of E.piphany's outstanding capital stock, the exercise price of any
incentive stock option granted must be at least equal to 110% of the fair market
value on the grant date and the term of such incentive stock option must not
exceed five years. The term of all other options granted under the 1999 stock
plan may not exceed ten years.

     The 1999 stock plan provides that if E.piphany merges with or into another
corporation, or sells substantially all of its assets, each option and stock
purchase right must be assumed or an equivalent option or stock purchase right
substituted for by the successor corporation. If the outstanding options and
stock purchase rights are not assumed or substituted for by the successor
corporation, the optionees shall become fully vested in and have the right to
exercise such options or stock purchase rights. If an option or stock purchase
right becomes fully vested and exercisable in the event of a merger or sale of
assets, the administrator must notify the optionee that the option or stock
purchase right is fully exercisable for a period of 15 days from the date of the
notice, and the option or stock purchase right will terminate upon the
expiration of the 15 day period.

RightPoint 1996 Stock Option Plan

     In connection with the acquisition of RightPoint Software, Inc., E.piphany
assumed each outstanding and unexercised option granted under the RightPoint
Software, Inc. (formerly Datamind Corporation) 1996 Stock Option Plan. The
RightPoint 1996 Stock Option Plan provided for the grant of incentive stock
options and non-statutory stock options to employees, consultants and directors
of RightPoint Software, Inc. As of March 31, 2000, there were options to
purchase 412,026 shares of our common stock outstanding under the RightPoint
1996 Stock Option Plan. E.piphany will not grant additional options under the
RightPoint 1996 Stock Option Plan.

1999 Employee Stock Purchase Plan

     E.piphany's 1999 employee stock purchase plan was adopted by E.piphany's
board of directors in June 1999, and approved by the stockholders in July 1999.
As of March 31, 2000, a total of 3,081,964 shares of E.piphany's common stock
have been reserved for issuance under the 1999 purchase plan, plus annual
increases equal to the lesser of: (a) 2,000,000 shares, (b) 4% of the
outstanding shares on such date or (c) a lesser amount determined by E.piphany's
board of directors. As of March 31, no shares have been issued under the 1999
purchase plan.

     The 1999 purchase plan, which is intended to qualify under Section 423 of
the Internal Revenue Code, contains consecutive, overlapping, twenty-four month
offering periods. Each offering period includes four six-month purchase periods.
The offering periods generally start on the first trading day on or after May 1
and November 1 of each year, except for the first such offering period which
commenced on September 21, 1999 and ends on the last trading day on or before
October 31, 2001.

                                       121
<PAGE>   128

     Employees are eligible to participate if they are customarily employed by
E.piphany or any participating subsidiary for at least 20 hours per week and for
more than five months in any calendar year. However, employees may not be
granted an option to purchase stock under the 1999 purchase plan if they either:

     - immediately after grant, own stock possessing 5% or more of the total
       combined voting power or value of all classes of our capital stock, or

     - hold rights to purchase stock under E.piphany's employee stock purchase
       plans which accrue at a rate which exceeds $25,000 worth of stock for
       each calendar year.

     The 1999 purchase plan permits participants to purchase E.piphany's common
stock through payroll deductions of up to 15% of the participant's
"compensation." Compensation is defined as the participant's base straight time
gross earnings, overtime, shift premium and bonuses, but excludes other
compensation. The maximum number of shares a participant may purchase during a
single purchase period is 20,000 shares.

     Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each purchase period. The price of stock
purchased under the 1999 purchase plan is generally 85% of the lower of the fair
market value of the common stock either:

     - at the beginning of the offering period, or

     - at the end of the purchase period.

     In the event the fair market value at the end of a purchase period is less
than the fair market value at the beginning of the offering period, the
participants will be withdrawn from the current offering period following
exercise and automatically re-enrolled in a new offering period. The new
offering period will use the lower fair market value as of the first date of the
new offering period to determine the purchase price for future purchase periods.
Participants may end their participation at any time during an offering period,
and they will be paid their payroll deductions to date. Participation ends
automatically upon termination of employment with E.piphany.

     Rights granted under the 1999 purchase plan are not transferable by a
participant other than by will, the laws of descent and distribution, or as
otherwise provided under the 1999 purchase plan. The 1999 purchase plan provides
that, in the event of a merger with or into another corporation or a sale of
substantially all of E.piphany's assets, each outstanding option may be assumed
or substituted for by the successor corporation. If the successor corporation
refuses to assume or substitute for the outstanding options, the offering period
then in progress will be shortened and a new exercise date will be set. The new
exercise date will be set prior to the proposed date of the merger or sale of
assets.

     E.piphany's board of directors has the authority to amend or terminate the
1999 purchase plan, except that they may not adversely affect any outstanding
rights to purchase stock under the 1999 purchase plan. However, the board of
directors may terminate an offering period on any exercise date if the board
determines that the termination of the 1999 purchase plan is in E.piphany's best
interest and the best interest of E.piphany's stockholders. Notwithstanding
anything to the contrary, the board of directors may in its sole discretion
amend the 1999 purchase plan to the extent necessary and desirable to avoid
unfavorable financial accounting consequences by altering the purchase price for
any offering period, shortening any offering period or allocating remaining
shares among the participants. The 1999 purchase plan will terminate
automatically on September 21, 2009 unless terminated earlier by E.piphany's
board of directors.

                                       122
<PAGE>   129

401(k) Plan

     In January 1999, E.piphany adopted a 401(k) plan to provide eligible
employees with a tax preferential savings and investment program. Employees
become eligible to participate in the 401(k) plan on the first day they perform
an hour of service for E.piphany. Eligible participants may elect to reduce
their current compensation up to the lesser of 15% of eligible compensation or
the statutorily prescribed annual limit, currently $10,000, and have such
reduction contributed to the 401(k) plan. The 401(k) plan permits, but does not
require, E.piphany to make additional matching contributions to the 401(k) plan
on behalf of eligible participants. E.piphany has not made any matching
contributions to the 401(k) plan to date. All contributions made by and on
behalf of participants are subject to a maximum contribution limitation
currently equal to the lesser of 25% of their compensation or $30,000 per year.
At the direction of each participant, the trustee of the 401(k) plan invests the
assets of the 401(k) plan in selected investment options. Contributions by
participants or by E.piphany to the 401(k) plan, and income earned on plan
contributions, are generally not taxable to the participants until withdrawn,
and contributions by E.piphany, if any, are generally deductible by E.piphany
when made.

CHANGE IN CONTROL, SEVERANCE AND EMPLOYMENT ARRANGEMENTS

     In connection with E.piphany's hiring of Roger S. Siboni as its President
and Chief Executive Officer in July 1998, E.piphany sold 1,600,000 shares of its
common stock to him at a purchase price of $0.40 per share in exchange for a
promissory note and cash. E.piphany has a right to repurchase these shares of
stock at a price of $0.40 per share. E.piphany's right to repurchase Mr.
Siboni's shares lapses as to 1/48 of his total number of shares at the end of
each month after May 1, 1998. As of April 1, 2000, E.piphany's repurchase right
had lapsed with respect to 766,667 of Mr. Siboni's shares, leaving 833,333 of
his shares subject to the repurchase right. However, E.piphany's right to
repurchase Mr. Siboni's shares terminates as to all of his shares upon a change
in control of E.piphany in which Mr. Siboni is not given equivalent compensation
and title in the post change of control entity. See the sections entitled
"Certain Relationships and Related Transactions -- Common Stock Purchases and
Sales" and "-- Employee Loans."

     In a merger or a sale of substantially all of E.piphany's assets, if the
options under E.piphany's 1997 stock plan are not assumed or substituted for,
each outstanding option will terminate as of the closing of the merger or sale
of assets. In a merger or a sale of substantially all of E.piphany's assets, if
the options outstanding under E.piphany's 1999 stock plan are not assumed or
substituted, each outstanding option will vest fully and become immediately
exercisable.

     In connection with E.piphany's acquisition of RightPoint, E.piphany entered
into an employment agreement with Gayle Crowell, E.piphany's Chief Privacy
Officer, and former President, Chief Executive Officer and Director of
RightPoint. Pursuant to her employment agreement, Ms. Crowell is guaranteed a
base salary at an annualized rate of $280,000 plus a bonus of not less than
$40,000 on an annualized basis. The agreement also guarantees Ms. Crowell
severance payments for up to 12 months in the event of a termination without
cause.

LIMITATIONS OF LIABILITY AND INDEMNIFICATION MATTERS

     E.piphany's certificate of incorporation limits the liability of directors
to the maximum extent permitted by Delaware law. Delaware law provides that
directors of a corporation will not be personally liable for monetary damages
for breach of their fiduciary duties as directors, except liability for any of
the following:

     - any breach of their duty of loyalty to the corporation or its
       stockholders,

     - acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law,

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions, or

     - any transaction from which the director derived an improper personal
       benefit.

This limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

     E.piphany's certificate of incorporation and bylaws provide that E.piphany
shall indemnify its directors and executive officers and may indemnify
E.piphany's other officers and employees and other agents to the fullest extent
permitted by law. E.piphany believes that indemnification under its bylaws
covers at least negligence and gross negligence on the part of indemnified
parties. E.piphany's bylaws also permit it to secure insurance on behalf of any
officer, director, employee or other agent for any liability arising out of his
or her actions in such capacity, regardless of whether E.piphany's bylaws would
permit indemnification.

     E.piphany has entered into agreements to indemnify its directors and
executive officers, in addition to the indemnification provided for in its
bylaws. These agreements, among other things, provide for indemnification of
E.piphany's directors and executive officers for expenses, judgments, fines and
settlement amounts incurred by any such person in any action or proceeding
arising out of such person's services as a director or executive officer or at
E.piphany's request. E.piphany believes that these provisions and agreements are
necessary to attract and retain qualified persons as directors and executive
officers.

     The foregoing purchases and sales were exempt from registration under the

COMMON STOCK PURCHASES AND SALES

     At the time of E.piphany's founding, E.piphany entered into stock purchase
agreements with Steven G. Blank and Eliot L. Wegbreit, founders of E.piphany. On
January 24, 1997, Mr. Blank and Dr. Wegbreit each purchased 2,100,000 shares of
E.piphany's common stock under their agreements at a purchase price of $0.0005
per share for $1,050 each. Mr. Blank was an officer of E.piphany and Dr.
Wegbreit was an officer of E.piphany and chairman of E.piphany's board of
directors. E.piphany had the right to repurchase Mr. Blank's and Dr. Wegbreit's
shares at their original purchase price of $0.0005 per share if E.piphany
terminated their respective employment for cause or upon their death or
disability. E.piphany's repurchase right lapsed as to 1/48 of the total number
of shares at the end of each month after November 1, 1996.

     In March 1999, Dr. Wegbreit resigned as Executive Vice President,
Engineering of E.piphany. In accordance with the terms of his stock purchase
agreement, Dr. Wegbreit's remaining shares of common stock are no longer subject
to E.piphany's repurchase right.

     On August 6, 1999, Steven G. Blank, who was at the time E.piphany's
Executive Vice President of Marketing, resigned from E.piphany to pursue other
interests. In connection with Mr. Blank's resignation, 125,000 shares of his
common stock were repurchased by E.piphany for a total purchase price of $62.50.
In accordance with the terms of his stock purchase agreement, Mr. Blank's
remaining shares of common stock are no longer subject to E.piphany's repurchase
right. Mr. Blank has agreed to continue as a consultant to E.piphany for up to
five days per month, until February 6, 2000. E.piphany will not be required to
pay any consulting fees to Mr. Blank, however, after the earlier of February 6,
2000 or the termination of the lock-up period which restricts Mr. Blank's sale
of his shares of E.piphany's common stock for up to 180 days following
E.piphany's initial public offering.

     In connection with E.piphany's hiring of Roger S. Siboni, E.piphany's
President and Chief Executive Officer, on July 7, 1998 E.piphany sold an
aggregate of 1,600,000 shares of common stock to Mr. Siboni at a purchase price
of $0.40 per share. Mr. Siboni paid for his shares with a promissory note in the
amount of $639,680 and $320 in cash. The principal amount of the note accrues
simple interest at a rate of 5.88% per year. See the section entitled
"Management -- Change in Control, Severance and Employment Arrangements."

     On January 16, 1998, in connection with E.piphany's Series B financing,
E.piphany sold an aggregate of 250,000 shares of its common stock to entities
affiliated with Kleiner Perkins Caufield & Byers, a 5% stockholder of E.piphany,
at a purchase price of $0.25 per share.

EMPLOYEE LOANS

     In addition to the loan to purchase stock given to Mr. Siboni, in
connection with his offer of employment as E.piphany's President and Chief
Executive Officer, Mr. Siboni received a loan of $175,000 for relocation
expenses. The entire amount of the loan was forgiven under the terms of the loan
on March 31, 1999. E.piphany has also offered to loan to Mr. Siboni up to
$250,000 per year for two years, drawable monthly. Mr. Siboni is currently
drawing down this loan at a rate of $20,833 per month. As of March 31, 2000, the
total outstanding principal amount of this loan is $63,000. In January 2000, the
board of directors awarded Mr. Siboni a bonus of $175,000 and applied this bonus
to the outstanding balance of the loan. This loan bears interest at a rate per
annum of 5.6%

                                       128
<PAGE>   135

compounded monthly and is repayable upon Mr. Siboni's first sales of E.piphany's
stock. Mr. Siboni is also eligible for an annual bonus of up to $125,000, which
is first applied to any outstanding loan balance that Mr. Siboni has with
E.piphany including the loan described above.

INDEMNIFICATION AGREEMENTS

     E.piphany has entered into agreements to indemnify its directors and
executive officers, in addition to indemnification provided for in its bylaws.
These agreements, among other things, provide for indemnification of E.piphany's
directors and executive officers for expenses, judgments, fines and settlement
amounts incurred by any such person in any action or proceeding arising out of
such person's services as a director or executive officer or at E.piphany's
request. E.piphany believes that these provisions and agreements are necessary
to attract and retain qualified persons as directors and executive officers.

     E.piphany believes that the shares sold in transactions described above
were sold at fair market value and the terms of the other arrangements described
above were no less favorable than E.piphany could have obtained from
unaffiliated third parties.

     In addition to the transactions described above, E.piphany has compensation
arrangements with directors and officers which are described under the section
entitled "Management."

                                OCTANE BUSINESS

     The discussion in this proxy statement/prospectus contains forward-looking
statements which involve risks and uncertainties. Octane's actual results could
differ materially from those discussed in the forward-looking statements.
Factors that could cause or contribute to such differences include, without
limitation, those discussed in this section and the section entitled "Risk
Factors," as well as those discussed elsewhere in this proxy
statement/prospectus.

OVERVIEW

     Octane Software, Inc. is a developer and marketer of a new category of
customer care software called Internet relationship management software.
Octane's Internet relationship management applications are 100 percent
Internet-based and enable businesses engaged in Internet commerce to acquire,
build and sustain long-term, loyal customer relationships. Octane's products
facilitate customer interactions across multiple channels of communication,
including Internet, email, text chat, phone and fax technologies. Covering both
automated and human-assisted communication channels, Octane's products can
collect, consolidate, analyze and distribute customer information captured
across multiple communication media to provide a complete view of the customer.

PRODUCTS

     Octane's product suite, Octane 2000, is designed for the unique customer
care requirements of companies engaged in Internet commerce. Octane 2000
consists of an Internet-based relationship management application called iCare
and an Internet application infrastructure called iBusiness. Octane99, the
predecessor product suite to Octane 2000, is no longer offered by Octane but is
still being supported by Octane for customers who have not yet transitioned to
Octane 2000.

     iCare and iBusiness

     iCare provides companies engaged in Internet commerce with a single system
to effectively manage the complete customer life cycle, including marketing,
sales, and service over multiple channels of communication. iBusiness is the
Internet application infrastructure upon which iCare is based. iBusiness
features a high-performance business process engine, support for multiple
communications channels and integration to third-party systems. iBusiness also
embodies real-time business intelligence and analysis functionality. All
application functionality is designated in Octane's visual development
environment, which is called iBusiness Studio. The heart of the iBusiness
application infrastructure is the iBusiness Transaction Server, a distributed
business process engine. Individual components of the system work independently
and allow the Internet relationship management product to scale to meet the
needs of an organization as it expands and as transaction volumes grow.

     Octane Online

     Octane's iCare application is available in a fully functional offering
hosted by Octane called Octane Online. Octane Online provides all the benefits
of the iCare solution without the up-front expense, resources, or time required
for traditional software-based implementations. Unlike client-server
applications that must overcome two-tier architectures, iCare is better suited
for remote hosting than traditional client-server software applications because
it is Internet-based. Octane Online users access their remote server through a
regular web browser, the same way users of the standard version of iCare access
the application.

CUSTOMERS

     Octane targets both business-to-consumer and business-to-business segments
of the Internet commerce marketplace. Octane's customers include traditional
brick-and-mortar companies seeking to establish an Internet presence, as well as
Internet-only "dot.com" companies. As of March 31, 2000, over 60 customers have
entered into agreements to purchase software licenses since Octane first began
shipping its products in the third quarter of 1999. Critical Path, EDS
Cashiering and Ybook accounted for 17%, 24% and 24%, respectively, of Octane's
revenue for the year ended December 31, 1999, and, IVUS and Total Solutions
accounted for 22% and 10% of Octane's revenue, respectively, for the three
months ended March 31, 2000.

PROFESSIONAL SERVICES AND CUSTOMER SUPPORT

     Octane offers a range of professional services to its clients that includes
support, consulting and education resources. Octane offers a broad range of
consulting services including needs analysis, product implementation,
configuration, integration and customization in order to meet customer-specific
Internet commerce requirements. Consulting services are delivered by Octane
consulting specialists as well as through implementation partners. Octane also
offers extensive training programs for its customers and partners to accelerate
implementation and end-user adoption of Octane solutions. Octane also offers a
full range of customer support services.

SALES AND MARKETING

     Octane sells its products through a direct sales force and indirectly
through resellers, distributors, application service providers and outsourcers.
As of March 31, 2000, Octane's sales and marketing force consisted of 84
professionals, including sales representatives, major account representatives,
sales engineers, channel/partner salespeople and marketing professionals. Octane
has salespeople located in sales offices in cities in the United States and in
the United Kingdom, Germany and Australia. Octane has also entered into reseller
agreements with several companies including TeleTech, Eltrax, RISC Management,
e-Assist.com, Brigade Solutions, e-Convergent and MISNet. Some of these Octane
partners also host Octane applications as an application service provider and
provide a full range of services such as the outsourcing of contact center
management and staff. Octane currently has relationships with 10 domestic and
international resellers, distributors, application service providers and
outsourcers.

RESEARCH AND DEVELOPMENT

     Octane's research and development organization is responsible for product
and technology development and enhancements, quality assurance and product
architecture. Octane's research and development organization is divided into
several design teams, including the core development group that designs the
iBusiness Transaction Server, the application development group that designs the
iCare application, the database development group that designs Octane's
underlying data schema and data marts, and the tools development group that
designs iBusiness Studio and management tools. The research and development
organization also includes a Quality Assurance team, as well as the Product
Marketing organization. As of March 31, 2000, the research and development
organization consisted of 85 employees.

COMPETITION

     The market for Octane's Internet relationship management products is new,
rapidly evolving and is expected to become increasingly competitive as current
competitors expand their product offerings

                                       131
<PAGE>   138

and new companies enter the market. The main competitive factors in the Internet
relationship management market include:

     - adherence to emerging web-based technology standards,

     - integration with a variety of communications media,

     - adaptability, flexibility and scalability,

     - integration with other Internet commerce applications and legacy systems,

     - completeness of application functionality,

     - ease of application use, deployment and maintenance,

     - speed of implementation,

     - customer service, support and training, and

     - price and total cost of ownership.

     Octane has three primary sources of competition:

     - in-house and third-party custom development efforts,

     - client-server based customer relationship management applications, such
       as Siebel Systems, Nortel (Clarify) and PeopleSoft (Vantive), and
       stand-alone point-solutions for email response such as Kana and e-Gain,
       and

     - providers of other Internet commerce solutions, such as Kana (Silknet)
       and e-Gain.

     Potential future competitors of Octane include telecommunication and
networking vendors, as well as enterprise software vendors and system
integrators. There can be no assurance that Octane can maintain its competitive
position against current and potential future competitors, especially
competitors with longer operating histories, greater name recognition and
substantially greater financial, technical, marketing, management, service,
support and other resources.

FACILITIES

     Octane currently leases approximately 31,400 square feet of office space
for Octane's headquarters in two buildings in San Mateo, California. These
leases expire in 2002, 2004 and 2005. Octane also leases office space in
Atlanta, Boston, Chicago, London, Melbourne, Australia, New York and Pittsburgh.
Octane believes that its facilities are adequate for its current needs. Octane
is currently in the process of negotiating a new lease for its headquarters in
San Mateo, California.

                   OCTANE SELECTED HISTORICAL FINANCIAL DATA
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

     The following selected financial data and other operating information of
Octane as of and for the years ended December 31, 1997, 1998 and 1999, are
derived from Octane's consolidated financial statements, which have been audited
by Deloitte & Touche LLP, independent auditors, and are included elsewhere in
this proxy statement/prospectus. The financial data as of and for the three
months ended March 31, 1999 and 2000 are derived from Octane's unaudited
consolidated financial statements included elsewhere in this proxy
statement/prospectus. Octane has prepared this unaudited information on the same
basis as the audited consolidated financial statements and has included all
adjustments, consisting only of normal recurring adjustments that it considers
necessary for a fair presentation of its financial position and operating
results for such periods. When you read this selected financial data, it is
important that you also read the historical consolidated financial statements
and related notes included in this proxy statement/prospectus, as well as the
section of this prospectus entitled "Octane Management's Discussion and Analysis
of Financial Condition and Results of Operations." Historical results are not
necessarily indicative of future results.

                  OCTANE MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion and analysis of Octane's financial condition and
results of operations should be read in conjunction with Octane's consolidated
financial statements and notes thereto appearing elsewhere in this proxy
statement/prospectus. This discussion and analysis contains forward-looking
statements that involve risks and uncertainties. Actual results may differ
materially from those indicated in such forward-looking statements.

OVERVIEW

     Octane is a developer and marketer of a new category of customer care
software called Internet relationship management software. Octane's Internet
relationship management applications are 100 percent Internet-based and enable
businesses engaged in Internet commerce to acquire, build and sustain long-term,
loyal customer relationships. Octane's products facilitate customer interactions
across multiple channels of communication, including Internet, email, text chat,
phone and fax technologies. Covering both automated and human-assisted
communication channels, Octane's products can collect, consolidate, analyze and
distribute customer information captured across multiple communication media to
provide a complete view of the customer.

REVENUES

     Octane derives its revenue from:

      - licensing software, and

      - providing professional consulting, maintenance and support services.

     Product license revenue is recognized when:

      - persuasive evidence of an agreement exists,

      - the product has been delivered, and no uncertainty exists about customer
        acceptance,

      - the license fee is fixed or determinable, and

      - collection of the fee is probable.

     If the customer uses Octane to install the product, product license revenue
is deferred until installation has occurred. To date, Octane has been
responsible for substantially all of its product installations.

     Services revenue consists of fees from:

      - professional services, including integration of software, application
        development, training and software installation,

      - maintenance of Octane software, and

      - customer support.

     Octane recognizes professional services fees billed on a time-and-materials
basis as the services are performed. For fixed price arrangements, Octane
recognizes professional services fees upon the completion of specific
contractual milestone events, or based on an estimated percentage of completion
as work progresses. Octane's clients typically purchase maintenance agreements
annually. Octane recognizes revenue from maintenance agreements (the term of
which is typically one year) ratably over the remaining term of the maintenance
obligation.

                                       134
<PAGE>   141

COST OF REVENUES

     Cost of license revenues consists of costs to manufacture, package, and
distribute Octane's products. Cost of license revenues have been insignificant
to date because Octane typically distributes its software by permitting
customers to download its software from Octane's web site. Cost of service
revenues consists primarily of employee-related costs and third-party consultant
fees incurred to provide services for consulting projects, customer support, and
training.

OPERATING EXPENSES

     Operating expenses are classified into four general categories:

     - research and development expenses, which consists primarily of
       employee-related costs and fees for outside consultants and related costs
       associated with the development of new products, the enhancement of
       existing products, quality assurance, testing, and documentation,

     - sales and marketing expenses, which consists primarily of employee
       salaries, commissions, and costs associated with marketing programs,

     - general and administrative expenses, which consists primarily of employee
       salaries and other personnel related costs for executive, financial,
       legal, and accounting as well as other professional service fees, and

     - Stock based compensation expense, which consists of amortization of
       deferred compensation in connection with stock option grants and sales of
       stock to employees at exercise or sales prices below the deemed fair
       market value of Octane's common stock and compensation related to equity
       instruments issued to non-employees for services rendered.

     All charges to these operating expense categories are based on the nature
of the expenditures. The costs for facilities and fixed asset depreciation are
allocated to these categories based on headcount.

ACQUISITION

     On March 13, 2000, Octane acquired all of the outstanding capital stock of
Sneakerlabs, Inc., a developer of chat and web collaboration software and
services. In connection with the acquisition, Octane issued 1,049,992 shares of
its common stock and issued options to purchase approximately 69,000 shares of
Octane common stock. The acquisition was accounted for as a purchase in the
three month period ended March 31, 2000.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2000 AND 1999

REVENUES

     Total revenue increased to $3.5 million for the three months ended March
31, 2000 from $879,000 for the three months ended March 31, 1999. The increase
in revenue was primarily a result of the introduction of Octane's first software
product in the second quarter of 1999 and the related transition from a
primarily service-based business to a software product-based business.

     License revenues were $1.9 million for the three months ended March 31,
2000 compared to none for the three months ended March 31, 1999. The increase in
license revenues coincided with the introduction of the Octane 2000 product
suite.

     Total services revenues increased to $1.6 million for the three months
ended March 31, 2000 from $879,000 for the three months ended March 31, 1999.
Services revenues from activity relating to Octane's products increased to $1.5
million for the three months ended March 31, 2000 from none

                                       135
<PAGE>   142

for the three months ended March 31, 1999. This increase in services revenue
principally reflected an increase in overall services activity relating to
Octane's own software products, offset by a reduction in services activity
relating to third party software.

COST OF REVENUES

     Total cost of revenues increased to $1.5 million for the three months ended
March 31, 2000, from $570,000 for the three months ended March 31, 1999. Cost of
license revenues consists primarily of license fees paid to third parties under
technology license arrangements and have not been significant to date. Cost of
services revenues consists primarily of the costs of consulting and customer
service and support.

     Cost of services revenues increased to $1.5 million or 94% of services
revenue for the three months ended March 31, 2000, compared to $570,000 or 65%
of services revenues for the three months ended March 31, 1999. The cost of
services revenues increased on a percentage basis due to the time required to
train the existing consulting organization to support Octane's own products as
well as the hiring and training of employees to provide for anticipated growth
in consulting, customer support, and training services. The number of employees
engaged in services increased to 60 as of March 31, 2000 from 13 as of March 31,
1999.

OPERATING EXPENSES

     Research and development expenses consist primarily of personnel and
related costs associated with our product development efforts. Research and
development expenses increased to $2.4 million for the three months ended March
31, 2000, from $735,000 for the three months ended March 31, 1999. This increase
primarily resulted from salaries associated with newly hired development
personnel. The number of employees engaged in research and development increased
to 85 as of March 31, 2000 from 24 as of March 31, 1999.

     Sales and marketing expenses consist primarily of employee salaries,
benefits and commissions, and the costs of trade shows, seminars, promotional
materials and other sales and marketing programs. Sales and marketing expense
increased to $5.4 million for the three months ended March 31, 2000, from
$773,000 for the three months ended March 31, 1999. The increase primarily
resulted from salaries associated with newly hired sales and marketing
personnel, commissions from licenses of Octane99 and Octane2000, and an increase
in marketing programs. The number of employees engaged in sales and marketing
duties increased to 84 as of March 31, 2000 from 16 as of March 31, 1999.

     General and administrative expenses consist primarily of employee salaries
and related expenses for executive, finance and administrative personnel.
General and administrative expenses increased to $4.0 million for the three
months ended March 31, 2000, from $511,000 for the three months ended March 31,
1999. A charge of $1.6 million was taken for goodwill amortization related to
the Sneakerlabs acquisition, which was completed on March 13, 2000. The
remaining increase primarily resulted from salaries associated with newly hired
personnel and related costs required to manage growth and facilities expansion.
The number of employees engaged in general and administrative duties increased
to 34 as of March 31, 2000 from 8 as of March 31, 1999.

     Stock-based compensation increased to $4.4 million for the first quarter of
2000 from $95,000 for the first quarter of 1999. This increase principally
resulted from an increase in stock option grant activity coupled with a more
rapid rate of increase in the deemed fair market value of Octane's common stock.

                                       136

RESULTS OF OPERATIONS

FISCAL YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

REVENUE

     Total revenue increased to $3.5 million in 1999 from $2.9 million for 1998.
Prior to the fourth quarter of 1999, Octane's revenues were derived from the
implementation of third party software products. Octane introduced its first
software product in the second quarter of 1999 and first began recognizing
product revenues in the fourth quarter of 1999. The increase in revenue was
primarily a result of the introduction of Octane's software product and the
related transition from a primarily services-based business. Octane's 1997
revenues of $248,000 consisted of entirely services revenue and reflected the
fact that Octane was only in operation for a limited portion of the year and
only provided professional services at that time.

     License revenues were $647,000 in 1999. Octane had no license revenues in
either 1998 or 1997. The increase in license revenues coincided with the
introduction of the Octane99 product suite, which was replaced by the Octane
2000 product suite.

     Services revenue decreased to $2.8 million for 1999 from $2.9 million for
1998. This decrease in services revenue reflected reduction in services activity
relating to third party software offset by an increase in consulting activity
relating to Octane's own software products.

COST OF REVENUES

     Total cost of revenues remained at $1.7 million in 1999, when compared to
the fiscal year ended December 31, 1998.

     Cost of license revenues have been insignificant for all periods.

     Cost of services revenue remained at $1.7 million, or 59% of services
revenue in 1999, compared to $1.7 million, or 56% of services revenue, in 1998
and $139,000, or 56% of services revenue, in 1997. The cost of services revenue
increased on a percentage basis during 1999 due to reduced productivity caused
by the need to train the existing consulting organization to support Octane's
own products as well as the hiring and training of employees to provide for
anticipated growth in consulting, customer support, and customer training. The
number of employees engaged in services increased to 37 as of December 31, 1999
from 17 as of December 31, 1998 and 2 as of December 31, 1997.

OPERATING EXPENSES

     Research and development expenses increased to $4.5 million in 1999, from
$1.1 million in 1998 and $50,000 in 1997. This increase primarily resulted from
salaries associated with newly hired development personnel. The number of
employees engaged in research and development increased to 53 as of December 31,
1999 from 19 as of December 31, 1998 and 1 as of December 31, 1997.

     Sales and marketing expenses increased to $6.8 million in 1999, from
$515,000 in 1998. The increase primarily resulted from salaries associated with
newly hired sales and marketing personnel, sales commissions from licenses of
Octane99, and an increase in marketing programs. The number of employees engaged
in sales and marketing duties increased to 41 as of December 31, 1999 from 8 as
of December 31, 1998. Octane had no sales and marketing personnel or other
expenses during the fiscal year ended December 31, 1997 as it had not yet
introduced any products.

     General and administrative expenses increased to $3.8 million in 1999, from
$1.1 million in 1998 and $34,000 in 1997. These increases primarily resulted
from salaries associated with newly hired personnel and related costs required
to manage growth and facilities expansion. The number of

                                       137
<PAGE>   144

employees engaged in general and administrative duties increased to 11 as of
December 31, 1999 from 7 as of December 31, 1998 and 1 as of December 31, 1997.

     Stock-based compensation increased to $1.2 million for 1999 from none in
1998 and 1997, principally as a result of an increase in stock option grant
activity coupled with the rapid rise in deemed fair market value of Octane's
common stock.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash used in operating activities totalled $7.1 million and $1.4
million for the three months ended March 31, 2000 and 1999, respectively. Cash
used in operating activities for each period resulted primarily from net losses
in those periods. Net cash used in operating activities totaled $10.0 million
and $1.7 million for the years ended December 31, 1999 and 1998, respectively.
Cash used in operating activities for each period resulted primarily from net
losses in those periods, and to a lesser extent, increases in accounts
receivable. These uses of cash were partially offset by increases in accrued
liabilities and unearned revenues.

     Net cash provided (used in) in investing activities totaled ($1 million)
and $1.9 million for the three months ended March 31, 2000 and 1999,
respectively. The increase resulted primarily from the purchases of furniture
and equipment, consisting largely of computer servers and workstations. Net cash
provided (used in) in investing activities totaled $354,000 and ($2.6 million)
for the years ended December 31, 1999 and 1998, respectively. The decrease
resulted primarily from the sale of short-term investments offset, to a lesser
extent, by purchases of furniture and equipment, consisting largely of computer
servers and workstations.

     Net cash provided by financing activities totaled $30 million and $17,000
for the three months ended March 31, 2000 and 1999, respectively. The increase
was primarily due to the proceeds from Octane's Series C Financing. Net cash
provided by financing activities totaled $16.0 million and $6.2 million for the
years ended December 31, 1999 and 1998, respectively. The increase was due
primarily to the receipt of proceeds from Octane's 1999 equity financings.

     In April 1999, Octane entered into a loan agreement with a lending
corporation that allows the company to borrow up to a total of $1.5 million for
the purchase and financing of property and equipment. Borrowings under the loan
agreement bear interest at a fixed rate of 8.50% and are collateralized by the
purchased property and equipment. As of December 31, 1999, Octane had $537,272
outstanding under the loan agreement, which is payable as follows: $197,863 in
2000; $215,353 in 2001; and $124,056 in 2002. The loan agreement expires in June
2000 with all payment due as noted in the preceding sentence and contains
certain covenants and restrictions as to various matters, including dividend
payments. Octane does not have any other credit facilities.

     As of March 31, 2000, Octane's principal sources of liquidity were $30.6
million of cash and cash equivalents. In January and February 2000, Octane
conducted a private placement of its Series C preferred stock, raising $29
million in cash. Octane believes that its current cash and cash equivalents and
short-term investments will be sufficient to meet its anticipated liquidity
needs for working capital and capital expenditures for at least 12 months in the
absence of additional financing or consummation of the merger.

EFFECT OF RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998 and June 1999, FASB issued SFAS No. 133, Accounting for
Derivative Instruments and Hedging Activities and SFAS No. 137, Accounting for
Derivative Instruments and Hedging Activities: Deferral of the Effective Date of
SFAS No. 133. These statements define derivatives, require that all derivatives
be carried at fair value, and provide for hedge accounting when certain
conditions are met. SFAS No. 133, as amended, is effective for Octane in fiscal

                                    EXPERTS

     The audited financial statements of E.piphany, Inc. for the years ended
December 31, 1997, 1998 and 1999 included in this proxy statement/prospectus and
elsewhere in this registration statement have been audited by Arthur Andersen
LLP, independent public accountants, as indicated in their reports with respect
thereto, and are included in this proxy statement/prospectus in reliance upon
the authority of said firm as experts in giving said reports.

     Octane's consolidated financial statements as of December 1998 and 1999 and
for the period from September 9, 1997 (inception) through December 31, 1997 and
each of the years in the two-year period ended December 31, 1999 included in
this document have been audited by Deloitte & Touche LLP, independent auditors,
as stated in their report appearing herein, and have been so

                                       147
<PAGE>   154

included in reliance upon the report of such firm given upon their authority as
experts in accounting and auditing.

     The consolidated financial statements of RightPoint as of June 30, 1999 and
1998 for the years then ended included in this proxy statement/prospectus have
been included herein and in the registration statement in reliance upon the
report of KPMG LLP, independent certified public accountants, appearing
elsewhere herein, and upon the authority of said firm as experts in auditing and
accounting.

              CHANGE IN E.PIPHANY'S INDEPENDENT PUBLIC ACCOUNTANTS

     In July 1998, KPMG LLP resigned as E.piphany's independent public
accountants, as KPMG LLP became an integrator of E.piphany's products and
purchased E.piphany's preferred stock. The former independent accountants'
report on E.piphany's financial statements for the year ended December 31, 1997
did not contain an adverse opinion, a disclaimer of opinion or any
qualifications or modifications related to uncertainty, limitation of audit
scope or application of accounting principles. The former independent public
accountants' report does not cover any of E.piphany's financial statements in
this registration statement. KPMG LLP did not issue an audit opinion on
E.piphany's financial statements for any other period. There were no
disagreements with the former public accountants on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure with respect to E.piphany's financial statements up through the time
of dismissal that, if not resolved to the former accountants' satisfaction,
would have caused them to make reference to the subject matter of the
disagreement in connection with their report. In September 1998, E.piphany
retained Arthur Andersen LLP as its independent public accountants. The decision
to retain Arthur Andersen LLP was approved by resolution of E.piphany's board of
directors. Prior to retaining Arthur Andersen LLP, E.piphany had not consulted
with Arthur Andersen LLP regarding accounting principles.

               CHANGE IN OCTANE'S INDEPENDENT PUBLIC ACCOUNTANTS

     In February 2000, Octane terminated its relationship with
PricewaterhouseCoopers LLP for reasons unrelated to the preparation of Octane's
financial statements. There was no disagreement between Octane and
PricewaterhouseCoopers LLP regarding accounting principles. This registration
statement does not include any report on Octane's financial statements for any
period from Octane's former independent public accountants. In February 2000,
Octane retained Deloitte & Touche LLP as its independent public accountants. The
decision to retain Deloitte & Touche LLP was approved by resolution of Octane's
board of directors. Prior to retaining Deloitte & Touche LLP, Octane had not
consulted with Deloitte & Touche LLP regarding accounting principles. For
purposes of issuing its audit opinion included in this registration statement,
Deloitte & Touche LLP re-audited Octane's financial statements as of and for the
year ended December 31, 1998, and for the period from September 9, 1997 to
December 31, 1997 which had originally been audited by Octane's former
independent public accountants.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

     On January 4, 2000, E.piphany, Inc. acquired RightPoint Software, Inc.
("RightPoint"). The acquisition of RightPoint was accounted for under the
purchase method of accounting.

     In March 2000, E.piphany signed a definitive agreement to acquire Octane
Software, Inc. ("Octane"). When completed, the acquisition of Octane will also
be accounted for under the purchase method of accounting.

     The pro forma combined condensed statement of operations of E.piphany for
the twelve months ended December 31, 1999 assume that the acquisitions of
RightPoint and Octane took place on January 1, 1999. The pro forma combined
condensed statements of operations of E.piphany for the three months ended March
31, 2000 assume that the acquisition of Octane took place on January 1, 2000.
The statements combine E.piphany's, RightPoint's and Octane's consolidated
statements of operations for the twelve months ended December 31, 1999 and
E.piphany's and Octane's consolidated statements of operations for the three
months ended March 31, 2000, as if the acquisitions took place at the beginning
of each period.

     The pro forma combined condensed balance sheet as of March 31, 2000
combines E.piphany's and Octane's consolidated balance sheets as of March 31,
2000 as if the acquisition had been consummated on that date.

     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
proxy statement/prospectus and are subject to change based upon completion of
the transactions and final purchase price allocations, including completion of
third party appraisals.

     E.piphany's and Octane's condensed financial information included in these
pro forma financial statements is derived from their December 31, 1999 audited
consolidated financial statements and their March 31, 2000 unaudited condensed
consolidated financial statements included elsewhere in this proxy
statement/prospectus. The results of operations of RightPoint included in the
unaudited pro forma combined condensed statements of operations of the year
ended December 31, 1999 were derived from its unaudited consolidated financial
statements for the same period that have been included in this proxy
statement/prospectus.

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

     The historical consolidated financial statements of E.piphany, RightPoint
and Octane are included elsewhere in this proxy statement/prospectus and the
unaudited pro forma combined condensed information presented herein should be
read in conjunction with those consolidated financial statements and related
notes.

     E.piphany allocated approximately $22.0 million of the purchase price to
RightPoint's in-process research and development, which was expensed upon
consummation of the merger as it has not reached technological feasibility and,
in the opinion of management, has no alternative future use. This amount has not
been reflected in the accompanying pro forma statements of operations as it is a
nonrecurring charge.

     The total purchase price of the Octane acquisition has been allocated to
acquired assets based on estimates of their fair values. The purchase price of
approximately $2.7 billion has been assigned to the assets acquired as follows

     E.piphany expects to allocate approximately $25.0 million of the purchase
price to Octane's in-process research and development, which will be expensed
upon consummation of the merger as it has not reached technological feasibility
and, in the opinion of management, has no alternative future use. The estimated
amount is subject to adjustment based upon completion of third party appraisals.
This amount has not been reflected in the accompanying pro forma statements of
operations as it is a nonrecurring charge, but has been reflected as an
adjustment to accumulated deficit in the accompanying pro forma balance sheet.

     The adjustments to the unaudited pro forma combined condensed balance sheet
as of March 31, 2000 are as follows:

     (A) To offset the Octane deferred revenue and related uncollected
         receivable as of March 31, 2000.

                                       153
<PAGE>   160

      (B) To reflect Goodwill and other intangibles of approximately $2.7
          billion resulting from the acquisition of Octane.

      (C) To reflect the purchase price paid for Octane as follows: issuance of
          approximately 11,755,138 shares of our common stock and the assumption
          of options and warrants to purchase approximately 1,038,372 shares of
          our common stock, valued at approximately $2.7 billion and
          acquisition-related expenses of approximately $30.0 million. The
          valuation of the E.piphany common stock is based on its weighted
          average closing price three days prior to and three days following the
          announcement of the acquisition. The valuation of options and warrants
          to purchase E.piphany common stock is based upon the Black-Scholes
          valuation model.

     The adjustments to the pro forma combined condensed statements of
operations for the year ended December 31, 1999 assume the acquisitions occurred
on January 1, 1999 and are as follows:

      (D) To reflect the amortization of approximately $1.1 billion of estimated
          goodwill and other intangibles resulting from the RightPoint and
          Octane acquisitions. The intangible assets will be amortized over
          three years.

      (E) To remove the effect of the amortization of stock-based compensation
          taken by Octane.

      (F) To remove the effect of the accretion and deemed dividend on preferred
          stock assuming conversion occurred on January 1, 1999.

     The adjustments to the pro forma combined statements of operations for the
three months ended March 31, 2000 assume the Octane acquisition occurred on
January 1, 2000 and are as follows:

      (G) To remove the effect of the in-process research and development charge
          taken by E.piphany as a result of the RightPoint acquisition.

      (H) To reflect the amortization of approximately $222.9 million of
          estimated goodwill and other intangibles resulting from the Octane
          acquisition. The intangible assets will be amortized over three years.

      (I) To remove the effect of the amortization of stock-based compensation
          taken by Octane.

      (J) To remove the effect of the accretion and deemed dividend on preferred
          stock assuming conversion occurred on January 1, 2000.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To E.piphany, Inc.:

     We have audited the accompanying balance sheets of E.piphany, Inc. (a
Delaware corporation) as of December 31, 1998 and 1999, and the related
statements of operations, stockholders' equity and comprehensive loss, and cash
flows for each of the three years in the period ended December 31, 1999. These
financial statements are the responsibility of E.piphany'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 the United States. Those standards 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. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of E.piphany, Inc. as of
December 31, 1998 and 1999, and the results of its operations and its 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.

                         NOTES TO FINANCIAL STATEMENTS

 1. ORGANIZATION AND OPERATIONS

     E.piphany, Inc. ("E.piphany" or the "Company"), formerly Epiphany Marketing
Software, Inc., was incorporated in Delaware in November 1996, and develops and
markets software that companies can use to establish, maintain and continually
improve customer relationships across both Internet and traditional sales,
marketing and distribution channels. In 1997, E.piphany was in the development
stage and was primarily engaged in obtaining equity financing and performing
research and development activities. Although E.piphany began actively selling
its products in 1998 and no longer considers itself to be in the development
stage, it has not operated profitably to date and there are no assurances that
it will operate profitably in the future.

     E.piphany has incurred net operating losses since inception and, as of
December 31, 1999, had an accumulated deficit of $35.9 million. E.piphany is
subject to various risks associated with companies in a comparable stage of
development, including having a limited operating history; competition from
substitute products and larger competitors; dependence on a limited number of
customers; dependence on key individuals; and the ability to obtain adequate
financing to support its growth.

 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates in Preparation of Financial Statements

     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 amounts of expenses during the reporting period.
Actual results could differ from those estimates.

Statements of Cash Flows

     For purposes of the statements of cash flows, E.piphany considers all
highly liquid investments purchased with original maturities of three months or
less to be cash equivalents. Cash equivalents consist of amounts on deposit at a
commercial bank and investments in commercial paper and other securities.

Concentration of Credit Risk and Significant Customers

     E.piphany provides credit to its customers in the normal course of
business, performs ongoing credit evaluations of its customers and maintains
allowances for potential credit losses which, to date, have not been material.

     In September 1998, the President and Chief Executive Officer of E.piphany
was elected to the board of directors of Customer D. E.piphany recognized
$357,000 and $273,000 in revenue from this customer in 1998 and 1999,
respectively, and had $146,000 and $118,000 in accounts receivable due from
Customer D at December 31, 1998 and 1999, respectively. The majority of the
agreements relating to this revenue were entered into before the chief executive
officer was employed by E.piphany or elected to Customer D's board of directors.

     The President and Chief Executive Officer of E.piphany is a member of the
board of directors of an additional customer. E.piphany recognized a total of
$296,000 in revenue from this customer in 1999, and had a total of $280,000 in
accounts receivable at December 31, 1999 from this customer. An outside director
of E.piphany is also a member of the board of directors of this customer.

     An outside director of E.piphany is a member of the board of directors of
two additional customers. E.piphany recognized $233,000 and $704,000 in revenue
from these customers in 1998 and 1999, and had a total of $57,000 and $112,000
in accounts receivable as of December 31, 1998 and 1999, respectively. The first
agreement with one of these customers was entered into before the outside
director was elected to E.piphany's board of directors.

Software Development Costs

     Software development costs incurred prior to the establishment of
technological feasibility are included in research and development expenses.
E.piphany defines establishment of technological feasibility as the completion
of a working model. Software development costs incurred subsequent to the
establishment of technological feasibility through the period of general market
availability of the products are capitalized, if material, after consideration
of various factors, including net realizable value. To date, software
development costs that are eligible for capitalization have not been material
and have been expensed.

Stock-Based Compensation

     The Financial Accounting Standards Board ("FASB") issued Statement of
Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation," in October 1995. This accounting standard permits the use of
either a fair value based method of accounting or the method defined in
Accounting Principles Board Opinion 25 ("APB 25"), "Accounting for Stock Issued
to Employees" to account for stock-based compensation arrangements. Companies

to employ the method proscribed by APB 25 are required to disclose the pro forma
net income (loss) that would have resulted from the use of the fair value based
method. E.piphany has elected to continue to account for its stock-based
compensation arrangements under the provisions of APB 25, and accordingly, has
included in Note 6 the pro forma disclosures required under SFAS No. 123.

Revenue Recognition

     E.piphany generates several types of revenue including the following:

     License Fees. E.piphany's standard end user license agreement for
E.piphany's products provides for an initial fee to use the product in
perpetuity up to a maximum number of users. E.piphany also enters into other
license agreement types, which allow for the use of E.piphany's products,
usually restricted by the number of employees, the number of users, or the
license term. Fees from licenses are recognized as revenue upon contract
execution, provided all shipment obligations have been met, fees are fixed or
determinable, collection is probable, and vendor specific objective evidence
exists to allocate the total fee between all elements of the arrangement. Fees
from license agreements which include the right to receive unspecified future
products are recognized over the term of the arrangement or, if not specified,
the estimated economic life of the product.

     When licenses are sold together with consulting and implementation
services, license fees are recognized upon shipment, provided that (1) the above
criteria have been met, (2) payment of the license fees is not dependent upon
the performance of the consulting services, and (3) the services do not include
significant alterations to the features and functionality of the software. To
date, services have been essential to the functionality of the software products
for substantially all license agreements entered into which included
implementation services. For these arrangements and other arrangements which
don't meet the above criteria, both the product license revenues and services
revenues are recognized in accordance with the provisions of Statement of
Position ("SOP") 81-1, "Accounting for Performance of Construction Type and
Certain Production Type Contracts." When reliable estimates are available for
the costs and efforts necessary to complete the implementation services, the
Company accounts for the arrangements under the percentage completion contract
method pursuant to SOP 81-1. When such estimates are not available, the
completed contract method is utilized. License revenue recognized pursuant to
SOP 81-1 comprised 76% and 66% of total product revenue for the years ended
December 31, 1998 and 1999, respectively.

     E.piphany provides for sales returns based on historical rates of return
which, to date, have not been material.

     Maintenance Agreements. Maintenance agreements generally call for E.piphany
to provide technical support and software updates to customers. Revenue on
technical support and software update rights is recognized ratably over the term
of the maintenance agreement and is included in services revenue in the
accompanying statements of operations.

     Consulting, Implementation and Training Services. E.piphany provides
consulting, implementation and training services to its customers. Revenue from
such services, when not sold in conjunction with product licenses, is generally
recognized as the services are performed.

     As of December 31, 1999, $545,000 of accounts receivable was unbilled due
to services performed in advance of billings.

Advertising Costs

     The Company expenses all advertising costs as incurred. The Company does
not incur any direct-response advertising costs.

Comprehensive Income (Loss)

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which E.piphany adopted beginning on January 1, 1998. SFAS No. 130
establishes standards for reporting and display of comprehensive income and its
components in a full set of general purpose financial statements. The objective
of SFAS No. 130 is to report a measure of all changes in equity of an enterprise
that results from transactions and other economic events of the period other
than transactions with shareholders ("comprehensive income"). Comprehensive
income is the total of net income and all other non-owner changes in equity. For
each of the three years ended December 31, 1999, E.piphany's comprehensive
income did not differ materially from reported net loss.

Computation of Basic and Diluted Net Loss Per Share and Pro Forma Basic and
Diluted Net Loss Per Share

     Basic and diluted net loss per common share are presented in conformity
with SFAS No. 128, "Earnings Per Share," for all periods presented. In
accordance with SFAS No. 128, basic net loss per common share has been computed
using the weighted average number of shares of common stock outstanding during
the period, less shares subject to repurchase. Basic and diluted pro forma net
loss per common share, as presented in the statements of operations, has been
computed as described above and also gives effect to the conversion of the
convertible preferred stock (using the if-converted method) from the original
date of issuance (in thousands, except per share amounts).

     E.piphany has excluded all convertible preferred stock, warrants for
convertible preferred stock, outstanding stock options, and shares subject to
repurchase from the calculation of diluted net loss per common share because all
such securities are antidilutive for all periods presented. The total number of
shares excluded from the calculations of diluted net loss per share were
approximately 8,124,000, 14,952,000, and 16,256,000 for the years ended December
31, 1997, 1998 and 1999, respectively. See Note 6 for further information on
these securities.

Segment Reporting

     During 1998, E.piphany adopted SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information." SFAS No. 131 requires a new basis of
determining reportable business segments (i.e., the management approach). This
approach requires that business segment information used by management to assess
performance and manage company resources be the source for segment information
disclosure. On this basis, E.piphany is organized and operates as one business
segment, the design, development, and marketing of software solutions.

     During the years ended December 31, 1997, 1998 and 1999, E.piphany did not
generate significant revenues in foreign countries and did not have any material
assets in foreign countries.

Recent Accounting Pronouncements

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which requires companies to record
derivative financial instruments on the balance sheet as assets or liabilities,
measured at fair value. Gains or losses resulting from changes in the values of
those derivatives would be accounted for depending on the use of the derivative
and whether it qualifies for hedge accounting. The key criterion for hedge
accounting is that the hedging relationship must be highly effective in
achieving offsetting changes in fair value or cash flows. In June 1999, the FASB
issued SFAS No. 137, "Accounting For Derivative Instruments and Hedging
Activities -- Deferral of the Effective Date of FASB Statement No. 133," which
amends SFAS No. 133 to be effective for all fiscal quarters of all fiscal years
beginning after June 15, 2000 (or January 1, 2001 for E.piphany). Management
believes that this Statement will not have a material impact on the financial
condition or results of the operations of E.piphany.

     In December 1998, the AICPA issued Statement of Position ("SOP") 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions." SOP 98-9 amends SOP 97-2 and SOP 98-4 by extending the deferral
of the application of certain provisions of SOP 97-2 amended by SOP 98-4 through
fiscal years beginning on or before March 15, 1999. All other provisions of SOP
98-9 are effective for transactions entered into in fiscal years beginning after
March 15, 1999. E.piphany does not anticipate that this statement will have a
material impact on its statement of operations.

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 "SAB 101," "Revenue Recognition in Financial
Statements." SAB 101 provides guidance on applying generally accepted accounting
principles to revenue recognition issues in financial statements. We will adopt
SAB 101 as required in the first quarter of 2000. We do not expect the adoption
of SAB 101 to have a material impact on our consolidated results of operations
and financial position.

     All of the debt arrangements above are collateralized by substantially all
of E.piphany's assets. E.piphany must comply with certain covenants under some
of these arrangements including minimum deposits and liquidity ratios.

     The subordinated convertible debt facility lender had the option to convert
a portion of the outstanding borrowings under the facility to 351,563 shares of
E.piphany's Series C preferred stock at a price of $6.40 per share. The fair
value of the warrant at the date of issuance was determined to be $391,000 and
was estimated using the Black-Scholes model with the following assumptions:
risk-free interest rate of 5.6%; expected life of 0.25 years; and expected
volatility of 85%. This amount will be recognized as additional interest expense
over the term of this arrangement with the lender. As of December 31, 1999, this
warrant has been exercised.

     Borrowings outstanding as of December 31, 1999 are payable as follows (in

 5. PREFERRED STOCK

     Since inception, E.piphany has issued 11,560,000 shares of preferred stock.
These shares were converted to shares of common stock upon the closing of the
Company's initial public offering (IPO). All outstanding warrants to purchase

IPO, E.piphany authorized 5,000,000 shares of undesignated preferred stock for
future issuance.

 6. COMMON STOCK

     During January and February 1997, E.piphany issued 5,600,000 shares of

original purchase price. The repurchase right expires over a 48-month period. In
July 1998, E.piphany's chief executive officer purchased 1,600,000 shares of
common stock under a restricted stock purchase agreement in exchange for a
promissory note (see Note 8). Pursuant to the stock purchase agreement,
E.piphany has the right to repurchase the common stock at the original purchase
price. The repurchase right expires over a 48-month period. As of December 31,
1999, 1,189,583 shares of common stock were subject to repurchase under these
founders agreements. All exercised but unvested stock options are also subject
to repurchase by E.piphany at the original purchase price. As of December 31,
1999 2,115,282 shares of common stock were subject to repurchase under these
stock options agreements.

     Effective upon the closing of the IPO, the number of authorized shares of

Warrants

     In May 1997, E.piphany issued a warrant to purchase 22,124 shares of Series
A preferred stock at $1.13 per share in connection with obtaining a line of
credit. The fair value of the warrant at the date of issuance was estimated
using the Black-Scholes model with the following assumptions: risk-free interest
rate of 6.4%; expected life of 4 years; and expected volatility of 85%. The
value was determined to be immaterial. As of December 31, 1999, this warrant has
been exercised.

     In January 1998, E.piphany issued a warrant to purchase shares of Series B
preferred stock at $2.50 per share in connection with obtaining a line of credit
with a bank. The number of shares is calculated based on $97,500 plus a
percentage of borrowings under the revolving line of credit divided by the share
price. The fair value of the warrant at the date of issuance was estimated using
the Black-Scholes model with the following assumptions: risk-free interest rate
of 5.6%; expected life of 3 years; and expected volatility of 85%. The value was
determined to be immaterial. As of December 31, 1999, this warrant has been
exercised for 75,000 shares.

     In June 1999, E.piphany issued a warrant to purchase 31,250 shares of
Series C preferred stock at $3.38 per share in connection with obtaining an
equipment lease line. The warrant is exercisable immediately and expires in June
2009. The fair value of the warrant at the date of issuance was determined to be
$141,000 and was estimated using the Black-Scholes model with the following
assumptions: risk-free interest rate of 5.2%; expected life of 3 years; and
expected volatility of 85%. This amount will be recognized as additional
interest expense over the term of this arrangement with the lender.

     Upon the closing of the Company's IPO, all warrants to purchase preferred
stock converted to warrants to purchase common stock.

Stock-Based Compensation

     In connection with the grant of certain stock options to employees during
the years ended December 31, 1998 and 1999, the Company recorded deferred
compensation of approximately $5.9 million, representing the difference between
the deemed value of the common stock for accounting purposes and the option
exercise price or stock sale price at the date of the option grant or stock
sale. Such amount is presented as a reduction of stockholders' equity and
amortized over the vesting period of the applicable options in a manner
consistent with FASB Interpretation No. 28. Approximately $0.7 million and $2.5
million was expensed during the years ended December 31, 1998 and 1999,
respectively. Compensation expense is decreased in the period of forfeiture for
any accrued but unvested compensation arising from the early termination of an
option holder's services.

     During the years ended December 31, 1997, 1998 and 1999, E.piphany recorded
stock-based compensation of $1,000, $58,000, and $435,000, respectively, related
to equity instruments issued to non-employees. Stock-based compensation related
to stock options to purchase common stock which are issued to non-employees is
determined based upon the fair value at the date of issuance in accordance with
the provisions of SFAS No. 123.

1999 Employee Stock Purchase Plan

     On June 30, 1999, the board of directors approved the adoption of
E.piphany's 1999 Employee Stock Purchase Plan (the "Purchase Plan"). A total of
2,000,000 shares of common stock have been reserved for issuance under the
Purchase Plan. The Purchase Plan permits eligible employees to purchase shares
of common stock through payroll deductions at 85% of the fair market value of
the common stock, as defined in the Purchase Plan. As of December 31, 1999, no
shares had been purchased.

Initial Public Offering

     On September 21, 1999, E.piphany completed an IPO of 4,772,500 shares of
its common stock at a price of $16.00 per share and received net proceeds of
approximately $69.9 million.

Stock Split

     On June 30, 1999, E.piphany's board of directors approved a 1-for-2 reverse
stock split of E.piphany's outstanding common and preferred shares which was
effective upon E.piphany's IPO. All share and per share information included in
these financial statements have been retroactively adjusted to reflect this
reverse stock split.

Stock Options

     In 1997, E.piphany adopted the 1997 Stock Plan (the "1997 Plan") under
which incentive stock options and nonstatutory stock options may be granted to
employees and consultants of E.piphany. The exercise price for incentive stock
options is at least 100% of the fair market value on the date of grant for
employees owning less than 10% of the voting power of all classes of stock and
at least 110% of the fair market value on the date of grant for employees owning
more than 10% of the voting power of all classes of stock. For nonstatutory
stock options, the exercise price is at least 110% of the fair market value on
the date of grant for employees owning more than 10% of voting power of all
classes of stock and at least 85% for employees owning less than 10% of the
voting power of all classes of stock. Options generally expire in 10 years.
Options are immediately exercisable, but shares

so purchased vest over periods determined by the board of directors, generally
four years. Upon termination of employment, unvested shares may be repurchased
by E.piphany for the original purchase price.

     On June 30, 1999, the board of directors approved the adoption of
E.piphany's 1999 Stock Plan (the "1999 Plan"). A total of 3,500,000 shares of
common stock have been reserved for issuance related to stock options under the
1999 Plan. As of December 31, 1999, 203,797 shares have been granted.

     E.piphany's board of directors determined that no further options would be
granted under the 1997 Plan after the IPO. In addition to the 3,500,000 shares
authorized for the 1999 Plan, the 1997 Plan options authorized but not granted
as of the IPO date were made available for grant under the 1999 Plan.
Accordingly as of December 31, 1999, an aggregate of 3,410,816 shares were
available for future option grants under the 1999 Plan.

     E.piphany accounts for its stock option plans pursuant to APB 25 whereby
the difference between the exercise price and the fair value at the date of
grant is recognized as compensation expense. Had compensation expense for stock
option plans been determined consistent with SFAS No. 123, net losses would have
increased to the following pro forma amounts (in thousands, except per share
amounts):

     As of December 31, 1999, E.piphany had net operating loss carryforwards of
approximately $27.5 million and $19.7 million for federal and state tax
purposes, respectively. The federal net operating loss and other credit
carryforwards expire on various dates beginning on 2012 through 2019. The state
net operating loss carryforwards will expire in 2004.

     Under current tax law, net operating loss and credit carryforwards
available to offset future income in any given year may be limited upon the
occurrence of certain events, including significant changes in ownership
interests.

     The provision for income taxes differs from the expected tax benefit amount
computed by applying the statutory federal income rate of 34% to income (loss)
before taxes as follows:

8. RELATED PARTY TRANSACTIONS

     In 1998, E.piphany loaned its chief executive officer $175,000 for
relocation expenses. In accordance with the loan agreement, the entire amount of
the loan was forgiven on March 31, 1999. The loan was charged to compensation
expense and is included in general and administrative expense in the
accompanying statement of operations for the year ended December 31, 1998. The
chief executive officer was also offered a loan of $250,000 per year for two
years, drawable monthly. This loan bears interest at 5.6% per annum compounded
monthly and is repayable by the officer's first stock sales. As of December 31,
1999, $368,000 was outstanding on this loan. As the repayment of this amount was
contingent on future stock sales, this amount has been expensed as paid.

under the loan were charged to compensation expense in the period in which the
amounts were loaned to the officer, and thus, $104,000 and $250,000 are included
in general and administrative expense in the accompanying statements of
operations for the years ended December 31, 1998 and 1999, respectively. This
chief executive officer was also given a loan to purchase 1,600,000 shares of
common stock at $0.40 per share. This loan is due on July 1, 2008 and accrues
interest at 5.88% per annum.

9. 401(k) PLAN

     In January 1999, the Company adopted a 401(k) plan (the "401(k)").
Participation in the 401(k) is available to all employees. Employees are
eligible to participate in the 401(k) at any time beginning with their first day
of employment. Each participant may elect to contribute an amount up to 15% of
his or her annual base salary plus commission and bonus, but not to exceed the
statutory limit as prescribed by the Internal Revenue Code. The Company may make
discretionary contributions to the 401(k). To date, no contributions have been
made by the Company.

10. ACQUISITIONS (UNAUDITED)

The RightPoint Acquisition

     On January 4, 2000, E.piphany acquired RightPoint Software, Inc. in a
merger transaction. Under the terms of the Merger Agreement, stockholders of
RightPoint exchanged approximately 0.1185 shares of E.piphany common stock for
each share of RightPoint common stock they owned at the time the merger was
consummated. In addition, options and warrants to acquire RightPoint common
stock were converted as a result of the merger into equivalent options and
warrants for E.piphany common stock, based upon the exchange ratio. E.piphany
expects that the costs directly related to the Merger will be approximately $4.8
million. The total purchase price was approximately $496.8 million, of which
approximately $22.0 million was allocated to in-process research and development
and expensed upon closing of the acquisition as it had not reached technological
feasibility and, in management's opinion, had no alternative future use. The
remaining purchase price consists principally of acquired intangibles and
goodwill which will be amortized over a period of 3 years.

The Octane Acquisition

     On March 15, 2000, E.piphany entered into a definitive agreement to acquire
Octane Software, Inc. Octane Software is a next-generation provider of
multi-channel customer interaction applications and infrastructure software for
sales, service and support. Octane Software enables companies to provide
real-time, interactive customer care to engage, acquire and retain customers in
the new Internet economy. Under the terms of the agreement, we will issue
approximately 12.8 million shares of its common stock to the stockholders of
Octane Software. The acquisition is subject to customary closing conditions,
including regulatory approval and the approval of E.piphany's and Octane
Software's stockholders.

     E.piphany will account for the acquisition under the purchase method of
accounting and E.piphany expects to allocate a portion of the purchase price to
intangible assets which will be amortized ratably over their estimated useful
lives. In addition, E.piphany expects to incur a write-off related to in-process
research and development upon closing of the transaction.

privately held eClass Direct, an application service provider of
permission-based e-mail marketing services, for approximately 750,000 shares of
E.piphany common stock. The acquisition will be accounted for as a purchase and
is subject to customary closing conditions, including the approval of eClass
Direct stockholders.

11. SECONDARY OFFERING (UNAUDITED)

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1. BASIS OF PRESENTATION

     The condensed consolidated financial statements included herein have been
prepared by the Company, without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations. However, the Company believes that the
disclosures are adequate to make the information presented not misleading. These
condensed consolidated financial statements should be read in conjunction with
the Company's audited financial statements and notes for the year ended December
31, 1999, included elsewhere in this proxy statement/prospectus.

     The unaudited condensed consolidated financial statements included herein
reflect all adjustments (which include only normal, recurring adjustments) which
are, in the opinion of management, necessary to state fairly the results for the
three month period ended March 31, 2000. The results for the three month period
ended March 31, 2000 are not necessarily indicative of the results expected for
the full fiscal year.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

     During the three months ended March 31, 2000, E.piphany established
subsidiaries primarily to extend its direct sales force into international
locations. The consolidated financial statements include the accounts of
E.piphany, Inc. and its wholly owned subsidiaries E.piphany (UK) Limited,
RightPoint Software, Inc., RightPoint Software S.A.R.L. and RightPoint LTD. All
significant intercompany accounts and transactions have been eliminated in
consolidation.

FOREIGN CURRENCY TRANSLATION

     The functional currency of the Company's subsidiaries is the local
currency. Accordingly, all assets and liabilities are translated into U.S.
dollars at the current exchange rate as of the applicable balance sheet date.
Revenues and expenses are translated at the average exchange rate prevailing
during the period. Gains and losses resulting from the translation of the
financial statements are reported as a separate component of stockholders'
equity. Foreign currency transaction gains and losses are included in other
income (expense) and as of March 31, 2000 these transactions have not been
material.

3. COMPREHENSIVE INCOME (LOSS)

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which E.piphany adopted beginning on January 1, 1998. SFAS No. 130
establishes standards for reporting and display of comprehensive income and its
components in a full set of general purpose financial statements. The objective
of SFAS No. 130 is to report a measure of all changes in equity of an enterprise
that results from transactions and other economic events of the period other
than transactions with shareholders ("comprehensive income"). Comprehensive
income is the total of net income and all other non-owner changes in equity. For
the three months ended March 31, 1999, and the three months ended March 31,
2000, E.piphany's comprehensive income (loss) did not differ materially from
reported net loss.

4. COMPUTATION OF BASIC AND DILUTED NET LOSS PER SHARE AND PRO FORMA BASIC AND
DILUTED NET LOSS PER SHARE

     Basic and diluted net loss per common share are presented in conformity
with SFAS No. 128, "Earnings Per Share," for all periods presented. In
accordance with SFAS No. 128, basic net loss per common share has been computed
using the weighted average number of shares of common stock outstanding during
the period, less shares subject to repurchase. Basic and diluted pro forma net
loss per common share, as presented in the statements of operations, has been
computed as described above and also gives effect to the conversion of the
convertible preferred stock (using the if-converted method) from the original
date of issuance.

     The following table presents the calculation of basic and pro forma basic
net loss per share (in thousands, except per share amounts):

</TABLE>

     E.piphany has excluded all convertible preferred stock, warrants for
convertible preferred stock, outstanding stock options, and shares subject to
repurchase from the calculation of diluted net loss per common share because all
such securities are antidilutive for all periods presented. The total number of
shares excluded from the calculations of basic and diluted net loss per share
were approximately 17,471,000 and 7,389,000 for the three months ended March 31,
1999 and March 31, 2000, respectively.

5. RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which requires companies to record
derivative financial instruments on the balance sheet as assets or liabilities,
measured at fair value. Gains or losses resulting from changes in the values of
those derivatives would be accounted for depending on the use of the derivative
and whether it qualifies for hedge accounting. The key criterion for hedge
accounting is that the hedging

                                      F-26

                                  (UNAUDITED)

relationship must be highly effective in achieving offsetting changes in fair
value or cash flows. In June 1999, the FASB issued SFAS No. 137, "Accounting For
Derivative Instruments and Hedging Activities -- Deferral of the Effective Date
of FASB Statement No. 133," which amends SFAS No. 133 to be effective for all
fiscal quarters of all fiscal years beginning after June 15, 2000 (or January 1,
2001 for E.piphany). This Statement will not have a material impact on the
financial condition or results of the operations of E.piphany.

     In December 1998, the AICPA issued Statement of Position ("SOP") 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions." SOP 98-9 amends SOP 97-2 and SOP 98-4 by extending the deferral
of the application of certain provisions of SOP 97-2 which were amended by SOP
98-4 through fiscal years beginning on or before March 15, 1999. All other
provisions of SOP 98-9 are effective for transactions entered into in fiscal
years beginning after March 15, 1999. E.piphany does not anticipate that this
statement will have a material impact on its statement of operations.

6. THE RIGHTPOINT ACQUISITION

     On January 4, 2000, E.piphany acquired RightPoint Software, Inc. in a
merger transaction. Under the terms of the Merger Agreement, stockholders of
RightPoint exchanged approximately 0.1185 shares of E.piphany common stock for
each share of RightPoint common stock they owned at the time the merger was
consummated. In addition, options and warrants to acquire RightPoint common
stock were converted as a result of the merger into equivalent options and
warrants for E.piphany common stock, based upon the exchange ratio. The total
purchase price was approximately $496.8 million, of which $22.0 million was
allocated to in-process research and development and expensed upon closing of
the acquisition as it has not reached technological feasibility and, in
management's opinion, had no alternative future use. Purchased intangibles,
representing purchase price in excess of identified tangible and intangible
assets, of approximately $479.3 million were recorded and are being amortized on
a straight-line basis over a useful life of three years. Accumulated
amortization was approximately $39.9 million at March 31, 2000.

     The value assigned to acquired in-process research and development was
determined by identifying research projects in areas for which technological
feasibility has not been established. The value was determined by estimating the
costs to develop the acquired in-process technology into commercially viable
products, estimating the resulting net cash flows from such projects, and
discounting the net cash flows back to their present values. The discount rate
includes a factor that takes into account the uncertainty surrounding the
successful development of the acquired in-process technology. If these projects
are not successfully developed, future revenue and profitability of the Company
may be adversely affected. Additionally, the value of the other purchased
intangible assets may be impaired.

     In connection with the acquisition, net assets acquired were as follows (in
thousands):

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
RightPoint Software, Inc.:

     We have audited the accompanying consolidated balance sheets of RightPoint
Software, Inc. and subsidiary (the Company) as of June 30, 1998 and 1999, and
the related consolidated statements of operations and comprehensive loss,
stockholders' equity, and cash flows for the years then ended. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of RightPoint
Software, Inc. and subsidiary as of June 30, 1998 and 1999, and the results of
their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   (INFORMATION AS OF DECEMBER 31, 1999 AND FOR THE SIX MONTHS THEN ENDED IS
                                   UNAUDITED)

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) DESCRIPTION OF THE COMPANY

     RightPoint Software, Inc. was originally incorporated under the laws of
France in 1991. The Company was reincorporated under the laws of California in
October 1995 and reincorporated under the laws of Delaware in July 1997. The
Company designs, develops, markets, and supports real-time marketing software
for business environments. The Company operates as one business segment.

(b) PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the financial
statements of the Company and its wholly owned subsidiary, RightPoint Software
France SARL (formerly neurOagent, S.A.). All significant intercompany accounts
and transactions have been eliminated.

(c) CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

     The Company considers all highly liquid investments with an original
maturity of three months or less when purchased to be cash equivalents. Cash
equivalents as of December 31 1999, June 30, 1999 and 1998 consisted primarily
of money market funds, recorded at cost, which approximates fair value.

     The Company classifies its investments as trading and records them at fair
market value.

(d) SOFTWARE DEVELOPMENT COSTS

     Statement of Financial Accounting Standard ("SFAS") No. 86, "Accounting for
the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed",
requires the capitalization of software development costs once technological
feasibility has been established. Software development costs are included in
research and development and expensed as incurred. To date, no software
development costs have been capitalized after technological feasibility was
reached, as such costs have not been significant.

(e) PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets, ranging
from three to five years. Equipment recorded under capital lease and leasehold
improvements are amortized using the straight-line method over the shorter of
the lease-term or estimated useful life of the asset.

(f) REVENUE RECOGNITION

     Revenues consist of fees for licenses of the Company's software products,
maintenance, support, consulting, and training.

     License revenues are recognized when persuasive evidence of an arrangement
exists, delivery has occurred, the fee is fixed and determinable and
collectibility is probable.

                                 AND SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
   (INFORMATION AS OF DECEMBER 31, 1999 AND FOR THE SIX MONTHS THEN ENDED IS
                                   UNAUDITED)

     Maintenance and support revenues are recognized ratably over the term of
the contract, which is generally 12 months. Revenues from consulting and
training are recognized when the services are performed.

(g) FOREIGN CURRENCY

     The functional currency of the Company's French subsidiary is the local
currency. All foreign assets and liabilities are translated into U.S. dollars at
the current exchange rates as of the applicable balance sheet date. Revenues and
expenses are translated at the average exchange rate prevailing during the
period. Gains and losses resulting from the translation of the subsidiary's
financial statements are reported as cumulative translation adjustment as a
component of accumulated other comprehensive income in stockholders' equity. Net
gains and losses resulting from foreign exchange transactions are included in
the consolidated statements of operations and were not significant during any of
the periods presented.

(h) USE OF ESTIMATES

     The preparation of consolidated 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 consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

(i) CONCENTRATIONS OF CREDIT RISK

     Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash, cash equivalents,
short-term investments and accounts receivable. The Company maintains its cash
and cash equivalents in commercial checking and money market accounts with
high-quality financial institutions.

     As of and for the year ended June 30, 1998, two customers comprised 21% and
20%, respectively, of revenue and 0% and 16%, respectively, of accounts
receivable. As of and for the year ended June 30, 1999, three customers
comprised approximately 41%, 13% and 12%, respectively of revenue and 5%, 52%
and 0%, respectively, of accounts receivable. As of and for the six months ended
December 31, 1999, three customers comprised 24%, 12% and 12%, respectively, of
revenue and 18%, 6% and 1%, respectively of accounts receivable.

(j) INCOME TAXES

     Income taxes are computed using the asset and liability method. Under this
method, deferred income tax assets and liabilities are determined based on the
differences between the financial reporting and tax bases of assets and
liabilities and are measured using the current enacted tax rates and laws.

(k) STOCK-BASED COMPENSATION

     The Company accounts for its stock-based compensation using the
intrinsic-value method prescribed in the Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees, and related interpretations.

     The Company provides additional pro forma disclosures as required under
SFAS No. 123, Accounting for Stock-Based Compensation.

(l) COMPREHENSIVE INCOME AND LOSS

     Comprehensive loss consists of net loss and foreign currency translation
adjustments, and is presented in the accompanying consolidated statements of
operations and comprehensive loss. Accumulated other comprehensive loss consists
entirely of cumulative foreign currency translation adjustments. No tax effects
have been recorded.

(m) COMPUTATION OF NET LOSS PER SHARE

     Basic net loss per common share has been computed using the weighted
average number of shares of common stock outstanding during the period, less
shares subject to repurchase. Basic and diluted pro forma net loss per common
share, as presented in the statements of operations, has been computed as
described above and also gives effect to the conversion of the convertible
preferred stock (using the if-converted method) from the original date of
issuance.

     Calculations of historical and pro forma net loss per share are as follows
(in thousands):

     The Company has excluded all convertible preferred stock, warrants for
convertible preferred stock, outstanding stock options, and shares subject to
repurchase from the calculation of diluted net loss per common share because all
such securities are antidilutive for all periods presented. The total number of
shares excluded from the calculations of diluted net loss per share were
approximately 15,098,000, 25,671,000, 18,157,000, and 28,553,000 for the years
ended June 30, 1998 and 1999 and the six months ended December 31, 1998 and
1999, respectively.

     Pro forma diluted net loss per share gives effect to the conversion of
convertible preferred stock. However, outstanding warrants, stock option, and
shares subject to repurchase have been excluded from the calculations of pro
forma diluted net loss per share because all such securities are antidilutive
for all periods presented. The total number of shares excluded from the
calculations of pro forma diluted net loss per share were approximately
6,239,000, 3,526,000 and 7,447,000 for the year ended June 30, 1999 and the six
months ended December 31, 1998 and 1999, respectively.

(n) NEW ACCOUNTING PRONOUNCEMENTS

     SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities". SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives), and for hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. For a derivative not designated as a hedging
instrument, changes in the fair value of the derivative are recognized in
earnings in the period of change. SFAS No. 133, as amended by SFAS No. 137,
"Deferral of the Effective Date of FASB Statement No. 133" is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000. Management does
not believe the adoption of SFAS No. 133 will have a material effect on the
Company's consolidated financial position.

     In July, 1999 the Company signed a five year lease agreement for its main
U.S. facilities. Annual rent is approximately $891,000 in the first year with
annual incremental increases to $1,042,000 in the fifth year. The lease expires

(4) FINANCING ARRANGEMENTS

REPAYABLE GRANT AGREEMENTS

     As of June 30, 1998 and 1999 and December 31, 1999, the Company had
$330,000, $236,000 and $123,000 respectively, outstanding in the form of an
interest-free repayable grant from a French organization. Under the grant
agreement, payment is due in fiscal 2000.

NOTE PAYABLE

     As of June 30, 1998, the Company had a balance outstanding of approximately
$140,000 under a bridge loan agreement that was signed in conjunction with a
convertible debt offering. All outstanding debt was subsequently converted into
Series E Preferred Stock in January 1999.

LEASE AGREEMENT

     As of December 31, 1999, the Company had a lease line of credit available
up to a minimum commitment amount of $400,000 and $100,000 for the financing of
equipment and leasehold improvements, respectively. Upon request and formal
approval by the Lessor, these lines would be extended for an additional $400,000
and $100,000, respectively. As of December 31, 1999 there was no outstanding
balance under this line of credit.

(5) STOCKHOLDERS' EQUITY

(a) CONVERTIBLE PREFERRED STOCK

     The rights, preferences, and privileges of the preferred stock are as
follows:

     - The holders of Series A, B, C, D, and E preferred stock are entitled to
       receive noncumulative annual dividends at the rate of $0.07, $0.18,
       $0.35, $0.18, and $0.11 per share, respectively, with certain adjustments
       for stock splits, stock dividends, recapitalization, and similar events,
       when and if declared by the Board of Directors, in preference and
       priority to any payment of dividends to holders of common stock.

       The liquidation preference for the Series A, B, C, D, and E preferred
       stock is $0.89, $2.27, $4.43, $2.30, and $1.38 per share, respectively,
       plus all declared but unpaid dividends. If the assets are insufficient to
       make payments in full to all holders of preferred stock, assets will be
       distributed ratably among the holders of preferred stock in proportion to
       the full amounts to which they would have otherwise been entitled. Any
       remaining assets shall be distributed ratably among the holders of common
       and preferred stock on an "as if converted" basis until such time that
       aggregate distributions to holders of Series A, B, C, D, and E preferred
       stock equals $1.78, $4.54, $8.86, $6.90, and $4.14 per share,
       respectively. After that time, any remaining assets will be distributed
       on a pro rata basis to the holders of common stock and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
   (INFORMATION AS OF DECEMBER 31, 1999 AND FOR THE SIX MONTHS THEN ENDED IS
                                   UNAUDITED)

       preferred stock, based on the number of shares of common stock held by
       each, assuming conversion of all preferred stock.

     - At June 30, 1999, each share of Series A, B, C, D and E preferred stock
       is convertible into 1.51, 1.55, 2.00, 1.20, and 1.00 shares of common
       stock subject to future adjustments for antidilution. Each share of
       preferred stock will automatically convert into one share of common
       stock, subject to certain adjustments for antidilution, upon the closing
       of an underwritten public offering with a per share price reflecting a
       valuation of the Company of at least $50,000,000, and with gross proceeds
       of at least $20,000,000 or the role of two-thirds of the holders of the
       preferred stocks, voting together.

     - The holders of preferred stock have voting rights on an "as if converted"
       basis.

     - The holders of preferred stock have certain registration rights and a
       right of first offer in future rounds of financing under certain
       conditions.

     The Company has reserved 19,431,358 shares of common stock for the
conversion of the preferred stock.

(b) STOCK-BASED COMPENSATION

     In connection with the grant of stock options and the sale of common stock
to certain employees during the six months ended December 31, 1999, the Company
recorded deferred compensation of approximately $7,224,000, representing the
difference between the fair value of the common stock and the option exercise
price or stock sale price at the date of the option grant or stock sale. Such
amount is presented as a reduction of stockholders' equity and amortized over
the vesting period of the applicable options in a manner consistent with
Financial Accounting Standards Board Interpretation No. 28. Approximately
$1,382,000 was expensed during the six months ended December 31, 1999.

(c) STOCK OPTION PLANS

     The Company adopted stock option plans in October 1995 and July 1996 that
provide for the issuance of incentive and nonstatutory options to purchase
shares of common stock. As of June 30, 1999, the Company has reserved 1,978,176
and 5,458,612 shares of common stock for issuance under the 1995 and 1996 plans,
respectively. Nonstatutory options may be granted to employees and consultants
and incentive options to employees. Options have a term no greater than 10 years
and generally vest 25% at the end of the first year and at a rate of 1/48 per
month thereafter. Options granted under the 1995 and 1996 plans may be exercised
prior to being fully vested. However exercised and unvested shares are subject
to repurchase by the Company at the exercise price. The Company's repurchase
right decreases as shares vest under the original option terms. As of June 30,
1998, 1999, and December 31, 1999 the number of shares outstanding and subject
to repurchase were 466,650, 31,169 and 30,827, respectively.

     Vesting of certain options accelerates in full upon a change in control of
the Company.

     Nonstatutory options are exercisable at a price not less than 85% of fair
market value of the stock at the date of grant, as determined by the Company's
Board of Directors, unless they are granted to an individual who owns more than
10% of the voting rights of all classes of stock, in which case the exercise
price shall be no less than 110% of the fair market value. Incentive stock
options are exercisable at a price not less than 100% of fair market value of
the stock at the date of grant, as determined by the Company's Board of
Directors, except when they are granted to an employee who owns greater than 10%
of the voting power of all classes of stock, in which case they are exercisable
at a price not less than 110% of fair market value.

     The Company has elected to continue using the intrinsic-value-based method
to account for all of its stock-based employee compensation plans. Pursuant to
SFAS No. 123, the Company is required to disclose the pro forma effects on the
net losses of the Company as if the Company had elected to use the fair value
approach to account for all of its stock-based employee compensation plans. Had
compensation cost for the Company's plans been determined consistent with the
fair value approach enumerated in SFAS No. 123, the Company's 1998 and 1999 net
losses would have increased to the following pro forma amounts (in thousands,
except per share data):

     For the years ended June 30, 1998 and 1999 and the six months ended
December 31, 1999, the fair value of each option was estimated using the minimum
value-based method on the date of grant with the following weighted-average
assumptions: no dividend yield; a risk-free interest rate of 7%; and an expected
life of five years.

the following assumptions: no dividend yield; risk-free interest rates ranging
between 5.5% and 7.0%; contractual lives ranging from five to ten years, and 65%
expected volatility. The fair value assigned to warrants is recorded as

federal and state income tax purposes of approximately $17,500,000 and
$11,100,000, respectively, available to reduce future income subject to income
taxes. The federal carryforward will expire from 2010 to 2019. The California
net operating loss carryforwards expire in 2003.

(7) RELATED PARTY TRANSACTIONS

     In June 1994, the Company's French subsidiary entered into an exclusive
license agreement with its founder, who is also a director, to use and market
certain technology in certain territories in exchange for an annual royalty fee
payable in quarterly installments. The Company also has an option to purchase
the technology for $700,000 in the event that the licensor fails to perform any
significant obligations or during the six months prior to the contract
expiration in 2004. This agreement was amended and restated in October 1995
under substantially the same terms and conditions. The amounts paid under this
license arrangement for the years ended June 30, 1999 and 1998, was $51,000 per
year.

     A second license for the technology was entered into on October 23, 1995,
between the Company and the same individual owner of this technology. Annual
royalties of $800 are payable under the agreement. The agreement licensed the
Company to distribute the technology in certain territories. The license expires
on July 18, 2004, with the licensee having the option to purchase all interests
in the technology for $10,000 provided that the Company's option to purchase the
first technology license is exercised.

     In January 1999, the Company entered into an agreement with Edify
Corporation, who is also a Series E preferred shareholder, to distribute certain
RightPoint software products at a discounted price to Edify for a minimum
nonrefundable distribution fee payable to the Company in quarterly installments
over 12 months. As of June 30, 1999 and December 31, 1999, the Company has
recognized $417,000 and $667,000, respectively, of this minimum nonrefundable
distribution fee as revenue.

To the Board of Directors and Shareholders of
Octane Software, Inc.:

     We have audited the accompanying consolidated balance sheets of Octane
Software, Inc. and subsidiaries (the "Company") as of December 31, 1998 and 1999
and the related consolidated statements of operations, shareholders' equity
(deficiency) and cash flows for the period from September 9, 1997 (inception) to
December 31, 1997 and for the years ended December 31, 1998 and 1999. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards 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. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company at December 31,
1998 and 1999 and the results of its operations and its cash flows for the
period from September 9, 1997 (inception) to December 31, 1997 and for the years

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
        PERIOD FROM SEPTEMBER 9, 1997 (INCEPTION) TO DECEMBER 31, 1997,
       THE YEARS ENDED DECEMBER 31, 1998 AND 1999 AND THREE MONTHS ENDED
                MARCH 31, 1999 (UNAUDITED) AND 2000 (UNAUDITED)

 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Organization -- Octane Software, Inc. (the "Company"), was formed on
September 9, 1997 (inception). The Company provides customer care solutions for
electronic commerce and other critical Internet operations. Since its inception,
the Company has primarily been involved in raising capital, recruiting
personnel, and developing and marketing its software products.

     Principles of Consolidation -- The consolidated financial statements
include the Company and its wholly-owned subsidiaries: Octane International and
Octane Australia Pty Ltd. All significant intercompany transactions and amounts
are eliminated in consolidation.

     Use of Estimates -- The preparation of consolidated 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 amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

     Concentration of Credit Risk -- Financial instruments that potentially
subject the Company to concentration of credit risk consist of trade
receivables. However, the Company's credit risk is mitigated by its credit
evaluation process and the reasonably short collection terms. The Company does
not require collateral or other security to support accounts receivable and
maintains reserves for potential credit losses.

     Cash and Equivalents -- The Company considers all highly liquid
investments, with a remaining maturity from the date of purchase of ninety days
or less, to be cash equivalents. Cash equivalents consisted of $1,264,494 and
$4,094,414 held in a money market account with a bank at December 31, 1998 and
1999, respectively, and $4,000,652 in commercial paper at December 31, 1999.

     Restricted Cash -- Restricted cash consisted of certificates of deposit
which were restricted from use pursuant to certain lease agreements.

     Short-Term Investments -- The Company's short-term investments are
classified as available-for-sale. The investments are carried at cost, which
approximated fair value at December 31, 1998. Short-term investments at December
31, 1998 consisted of $2,035,327 in certificates of deposit with a bank.

     Property and Equipment -- Property and equipment are stated at cost.
Depreciation is computed using the straight-line method over the estimated
useful lives of three to five years. Leasehold improvements are amortized over
the shorter of the lease term or the useful lives of the improvements.

     Software Development Costs -- Costs for the development of new software
products and substantial enhancements to existing software products are expensed
as incurred until technological feasibility has been established, at which time
any additional development costs would be capitalized in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 86, Computer

                                AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
        PERIOD FROM SEPTEMBER 9, 1997 (INCEPTION) TO DECEMBER 31, 1997,
       THE YEARS ENDED DECEMBER 31, 1998 AND 1999 AND THREE MONTHS ENDED
                MARCH 31, 1999 (UNAUDITED) AND 2000 (UNAUDITED)

Software To Be Sold, Leased, or Otherwise Marketed. Because the Company believes
its current process for developing software is essentially completed
concurrently with the establishment of technological feasibility, no costs have
been capitalized to date.

     Costs of Software Developed for Internal Use -- Effective January 1, 1999,
the Company adopted the American Institute of Certified Public Accountants
Statement of Position ("SOP") 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use, which requires the
capitalization of direct costs after management commits to funding a project it
believes will be completed and used to perform the functions intended. The
adoption of SOP 98-1 did not have a significant impact on the Company's
financial position, results of operations or cash flows as of and for the year
ended December 31, 1999, as the Company generally does not develop software for
internal use.

     Revenue Recognition -- The Company's revenue recognition policy is
consistent with SOP No. 97-2, Software Revenue Recognition, as amended. License
revenues are comprised of fees for the Company's software products. Revenue from
license fees is recognized when an agreement has been signed, delivery of the
product has occurred, no uncertainty exists about customer acceptance, the fee
is fixed or determinable, collectibility is probable and vendor-specific
objective evidence of fair value exists to allocate a portion of the total fee
to any undelivered elements of the arrangement. For electronic delivery, the
software is considered to have been delivered when the Company has provided the
customer with the access codes that allow for immediate possession of the
software. If the fee due from the customer is not fixed or determinable, revenue
is recognized as payments become due from the customer. If the customer uses the
Company to install the product, license revenue is deferred until installation
has occurred.

     Services revenues are comprised of revenue from support arrangements and
consulting fees. Support arrangements do not provide for specified upgrade
rights and provide technical support and the right to unspecified upgrades on an
if-and-when-available basis. Revenue from support arrangements (which are
typically one year) is recognized ratably over the remaining term of the support
agreement. If support or consulting services are included in an arrangement that
includes a license agreement, amounts related to support or consulting are
allocated based on vendor-specific objective evidence. Vendor-specific objective
evidence for support and professional services is based on the price when such
elements are sold separately, or, when not sold separately, the price as
established by management having the relevant authority. Consulting and training
revenue is recognized when provided to the customer.

     Income Taxes -- Deferred tax liabilities are recognized for future taxable
amounts, and deferred tax assets are recognized for future deductions, net of a
valuation allowance to reduce net deferred tax assets to amounts that are more
likely than not to be realized.

     Stock-Based Compensation -- The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with Accounting
Principles Board ("APB") Opinion No. 25, Accounting for Stock Issued to
Employees.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
        PERIOD FROM SEPTEMBER 9, 1997 (INCEPTION) TO DECEMBER 31, 1997,
       THE YEARS ENDED DECEMBER 31, 1998 AND 1999 AND THREE MONTHS ENDED
                MARCH 31, 1999 (UNAUDITED) AND 2000 (UNAUDITED)

     Impairment of Long-Lived Assets and Long-Lived Assets To Be Disposed
Of -- The Company evaluates its long-lived assets and certain identifiable
intangibles for impairment whenever events or changes in circumstances indicate
that the carrying amount of such assets or intangibles may not be recoverable.
Recoverability of assets to be held and used is measured by a comparison of the
carrying amount of an asset to future undiscounted net cash flows expected to be
generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceeds the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell.

     Certain Significant Risks and Uncertainties -- The Company operates in the
software industry, and accordingly, can be affected by a variety of factors. For
example, management of the Company believes that changes in any of the following
areas could have a significant negative effect on the Company in terms of its
future financial position, results of operations or cash flows: the ability to
increase revenues; the hiring, training and retention of key employees;
development of sales distribution capabilities; market acceptance of the
Company's products under development; fundamental changes in the technology
underlying the Company's software products; arbitration, litigation or other
claims against the Company; adverse changes in international market conditions;
successful and timely completion of product development efforts; product
introductions by competitors and the ability to obtain additional financing.

     Comprehensive Income (Loss) -- Comprehensive income, as defined, includes
all changes in shareholders' equity (deficiency) during a period from non-owner
sources. To date, the Company has not had any significant transactions that are
required to be reported in other comprehensive income (loss).

     Recently Issued Accounting Standards -- In June 1998, the FASB issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities, which
defines derivatives, requires that all derivatives be carried at fair value, and
provides for hedge accounting when certain conditions are met. SFAS No. 133 is
effective for the Company in fiscal 2001. Although the Company has not fully
assessed the implications of SFAS No. 133, the Company does not believe adoption
of this statement will have a material impact on its financial position or
results of operations.

     Unaudited Interim Financial Information -- The interim financial
information as of March 31, 2000 and for the three months ended March 31, 1999
and 2000 is unaudited and has been prepared on the same basis as the audited
financial statements. In the opinion of management, such unaudited financial
information includes all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the interim information.
Operating results for the three months ended March 31, 2000 are not necessarily
indicative of the results that may be expected for the year ending December 31,
2000.

 4. FINANCING ARRANGEMENTS

     In February 1999, the Company entered into a revolving line of credit
arrangement with a commercial bank that enables the Company to borrow up to a
total of $1,000,000. Borrowings under the revolving line of credit bear interest
at the bank's prime rate (8.25% at December 31, 1999) and are collateralized by
substantially all of the Company's assets. As of December 31, 1999, the Company
had no amounts outstanding under the revolving line of credit. The credit
arrangement expires in February 2000 and contains certain covenants and
restrictions as to various matters, including dividend payments.

     In April 1999, the Company entered into a loan agreement with a lending
corporation that allows the company to borrow up to a total of $1.5 million for
the purchase and financing of property and equipment through June 2000.
Borrowings under the loan agreement bear interest at a fixed rate of 8.50% and
are collateralized by the purchased property and equipment. As of December 31,
1999, the Company had $537,272 outstanding under the loan agreement, which is
payable as follows: $197,863 in 2000; $215,353 in 2001; and $124,056 in 2002.
The loan agreement contains certain covenants and restrictions as to various
matters, including dividend payments.

     The Company's deferred income tax assets at December 31 are comprised of
the following:

</TABLE>

     The Company has no income tax provision due to its history of operating
losses. Due to the uncertainty surrounding the realization of the benefits of
its favorable tax attributes in future tax returns, the Company has fully
reserved its net deferred tax assets as of December 31, 1998 and 1999.

     At December 31, 1999, the Company had net operating loss carryforwards of
approximately $13.9 million for federal and state income tax purposes. These
carryforwards begin to expire in 2018 for federal purposes and 2006 for state
purposes. Additionally, Section 382 of the Internal Revenue Code and the
applicable California law impose annual limitations on the use of net operating
loss carryforwards if there is a change in ownership, as defined, within any
three-year period. The utilization of certain net operating loss carryforwards
may be limited due to the Company's capital stock transactions.

 6. REDEEMABLE CONVERTIBLE PREFERRED STOCK

     During 1998, the Company issued 4,650,000 shares of Series A redeemable
convertible preferred stock for cash of $6,177,705 (net of issuance costs of
$22,295). During 1999, the Company issued 4,778,780 shares of Series B
redeemable convertible preferred stock for cash of $15,301,456 (net of issuance
costs of $28,492).

     At December 31, 1999, the rights, preferences, and privileges of the
holders of preferred stock are as follows (see Note 11 regarding subsequent
changes to certain provisions of the Series A and B preferred stock):

     - Dividends are noncumulative and payable only upon declaration by the
       Company's Board of Directors at a rate of $0.1067 and $0.2568 per share
       per annum for Series A and B preferred stock, respectively. No dividends
       on preferred stock or common stock have been declared by the Board from
       inception through December 31, 1999.

     - The holders of Series A and B preferred stock have voting rights
       equivalent to the number of shares of common stock into which it is
       convertible.

     - Each share of Series A and B preferred stock is convertible at any time
       into one share of common stock at the option of the holder, subject to
       adjustment to protect against dilution. The Company can be required to
       convert the preferred stock into common stock with the consent of not
       less than two-thirds of the outstanding Series A and B preferred
       stockholders, voting together as a single class. Each share of preferred
       stock automatically converts into common stock upon the closing of the
       sale of the Company's common stock in a public offering in which the
       aggregate cash proceeds, net of underwriting discounts and commissions,
       exceed $20,000,000 and the offering price equals or exceeds $10.00 per
       share.

     - In the event of liquidation, dissolution or winding up of the Company,
       the holders of Series A and B preferred stock are entitled to receive
       $1.3333 and $3.21 per share, respectively, as well as any declared but
       unpaid dividends on each share, prior to any distribution to the holders
       of common stock. Any remaining distributable assets of the Company would
       be distributed among the holders of Series A and B preferred stock and
       common stock on a pro rata basis, up to a total distribution of $4.00 and
       $9.63 per share of Series A and B preferred stock, respectively, if such
       distribution takes place prior to the first anniversary of the purchase
       date of Series B preferred stock, and up to a total distribution of
       $6.6666 and $16.05 per share of Series A and B preferred stock,
       respectively, if such distribution takes place on or after the first
       anniversary of the purchase date of the Series B preferred stock; after
       which any remaining assets are distributed solely to the holders of
       common stock.

     - At any time following 6 years after the purchase date of Series B
       preferred stock, but on a date within 30 days of a written request from
       the holders of a majority of the then outstanding Series A and B
       preferred stock, voting together as a single class, that all of the
       outstanding shares of preferred stock be redeemed, the Company shall
       redeem for cash a sum equal to the redemption value of $1.3333 and $3.21
       per share of Series A and B preferred stock, respectively, plus all
       declared but unpaid dividends.

     In April 1999, the Company issued a warrant to purchase 22,500 shares of
Series A preferred stock at $1.33 per share to a commercial bank in connection
with obtaining a line of credit. The warrant is exercisable after February 9,
2000 and expires June 30, 2005. The fair value of the warrant at the date of
issuance was estimated using the Black-Scholes model with the following
assumptions: risk free interest rate of 6%, contractual life of 6.5 years and
expected volatility of 75%. The value was deemed to be $22,429.

Deemed Dividend

     In December 1999, the Company sold 778,816 shares of Series B preferred
stock to an investor at $3.21 per share. In accordance with Emerging Issues Task
Force ("EITF") Issue No. 98-5, Accounting for Convertible Securities with
Beneficial Conversion Features or Contingently Adjustable Conversion Ratios, the
Company has recognized a deemed dividend of $2,500,000, representing the

 7. SHAREHOLDERS' EQUITY (DEFICIENCY)

Stock Splits

     In September 1998, the Board of Directors authorized a three for two stock
split of the Company's common stock and preferred stock. All share and per share
amounts in these consolidated financial statements have been adjusted to give
effect to this split.

Warrants

     In February 1999, the Company issued a warrant to purchase 18,750 shares of
common stock at $0.25 per share to a lending corporation in connection with
obtaining an equipment financing arrangement. The warrant is exercisable after
February 9, 2000 and expires June 30, 2005. The fair value of the warrant at
date of issuance was estimated using the Black-Scholes model with the following
assumptions: risk free interest rate of 6%, contractual life of 6.5 years and
expected volatility of 75%. The value was determined to be $34,098. Under the
terms of the equipment financing arrangement, the Company would be required to
issue an additional warrant to purchase 18,750 shares of common stock if
outstanding borrowings under the arrangement exceed $750,000. As of December 31,
1999, this warrant had not been earned or issued.

Common Stock

     A portion of the Company's shares of common stock were issued under
restricted stock purchase agreements. Under these agreements, in the event of
termination, the Company has the right to repurchase the common stock at the
original purchase price. The repurchase right expires over a 48 month period. At
December 31, 1998 and 1999 there were 2,581,792 and 1,735,923 shares subject to
repurchase, respectively.

     Pursuant to the restricted stock grant noted above, the Company accelerated
the vesting of certain shares subject to repurchase. Accordingly, the Company
recognized compensation expense of $113,000 during fiscal 1999.

     Certain shares were issued in exchange for notes receivable, which are full
recourse and additionally collateralized by the underlying shares of common
stock. These notes receivable have been included in shareholders' equity
(deficiency).

     On March 14, 2000, the Company amended certain common stock purchase and
option agreements with key employees to adjust for the effect of the merger
between the Company and E.piphany on accelerated vesting provisions set forth in
such agreements.

Stock Option Plans

     The Company's 1997 Stock Option Plan (the "Plan") provides for the granting
of stock options to employees and consultants of the Company. Options granted
under the Plan may be either incentive stock options or nonqualified stock
options. Incentive stock options ("ISOs") may be granted only to Company
employees (including officers and directors who are also employees).
Nonqualified stock options ("NSOs") may be granted to Company employees and
consultants. The Company has reserved 2,742,500 shares of common stock for
issuance under the Plan.

     Options under the Plan may be granted for periods of up to ten years. The
exercise price of an ISO and NSO shall not be less than 100% and 85% of the
estimated fair value of the shares on the date of grant, respectively, and the
exercise price of an ISO and NSO granted to a 10% shareholder shall not be less
than 110% of the estimated fair value of the shares on the date of grant.
Options are exercisable immediately in the event of termination, subject to
repurchase. This repurchase right generally lapses over the original vesting
schedule. To date, options granted generally vest over four years.

     Stock option activity is summarized as follows:

     At December 31, 1999, 587,934 shares remained available for future grant.

     Stock-Based Compensation -- In connection with options granted to purchase
common stock, the Company recorded deferred stock compensation of $5,880,709 in
1999. Such amounts represent, for employee stock options, the difference between
the exercise price and the fair value of the Company's common stock at the date
of grant, and for non-employee options, the deemed fair value of the option at
the date of vesting. The deferred charges for employee and non-employee options
are being amortized to expense through 2003. Stock-based compensation expense of
$1,218,769 was recognized during 1999. Deferred stock compensation and related
stock-based compensation expense of $71,070,812 and $4,433,188, respectively,
was recorded in the three-months ended March 31, 2000.

     Options granted to nonemployees -- The Company has granted options to
non-employees for consulting and legal services performed. The initial vesting
period for these options ranged from immediate vesting to vesting over 4 years
and an option exercise period of up to 10 years. Stock options issued to
non-employees are accounted for in accordance with provisions of SFAS No. 123,
Accounting for Stock-Based Compensation and EITF No. 96-18. Accounting for
Equity Instruments That Are Issued To Other Than Employees for Acquiring, or in
Conjunction With Selling, Goods or Services. The fair value of stock options
issued to non-employees was calculated using a risk free interest rate of 6%,
expected volatility of 75% and actual length of the option.

     During fiscal year 1998, options for 52,500 shares were granted at an
exercise price of approximately $0.01 and options for 4,500 shares were granted
at an exercise price of approximately $0.17. At December 31, 1998, unvested
non-employee options totaled 57,000 shares.

     During 1999, non-employee options for 27,250 shares were granted at an
exercise price of $0.25, options for 7,000 shares were granted at an exercise
price of $0.35, options for 15,750 shares were granted at an exercise price of
$0.45 and 1,500 shares were granted at an exercise price of $1.50. In connection
with these non-employee options, the Company recorded deferred stock
compensation of

unvested non-employee options totaled 50,551 shares and unamortized deferred
stock based compensation related to unvested options totaled $296,087.

Additional Stock Plan Information

     As discussed in Note 1, the Company accounts for its stock-based awards to
employees using the intrinsic value method in accordance with APB Opinion No.
25, Accounting for Stock Issued to Employees, and its related interpretations.

     SFAS No. 123, Accounting for Stock-Based Compensation, requires the
disclosure of pro forma net income (loss) had the Company adopted the fair value
method since the Company's inception. Under SFAS No. 123, the fair value of
stock-based awards to employees is calculated through the use of option pricing
models, even though such models were developed to estimate the fair value of
freely tradable, fully transferable options without vesting restrictions, which
significantly differ from the Company's stock option awards. These models also
require subjective assumptions, including expected time to exercise, which
greatly affect the calculated values.

     The Company's calculations for employee grants were made using the minimum
value model for grants with the following weighted average assumptions: expected
life; one year following vesting; risk free interest rate of 5.25% in 1998 and
6% in 1999; and no dividends during the expected term. In addition, volatility
of 70% was used for nonemployee grants valued under the fair value method. The
Company's calculations are based on a multiple award valuation approach and
forfeitures are recognized as they occur. If the computed values of the
Company's stock-based awards to employees had been amortized to expense over the
vesting period of the awards as specified under SFAS No. 123, net loss would
have been $1,421,998 and $14,789,619 for the years ended December 31, 1998 and
1999, respectively.

     The number and estimated weighted-average value per option for employee and
nonemployee awards, granted at December 31 are as follows:

11. SUBSEQUENT EVENTS

Proposed Acquisition by E.piphany, Inc.

     On March 15, 2000, the Company announced that it would be acquired by
E.piphany, Inc. ("E.piphany"), for approximately 12.8 million shares of
E.piphany common stock, pending the approval of both the Company's and
E.piphany's stockholders, certain regulatory approvals and completion of other
standard closing procedures.

Issuance of Series C Preferred Stock

     In January 2000, the Board and shareholders approved the amendment and
restatement of the Company's articles of incorporation to increase the total
number of authorized shares of common stock from 22,500,000 to 25,000,000 and to
increase the total number of authorized shares of preferred stock from 9,600,000
to 13,350,000 in the form of 3,750,000 shares of Series C preferred stock. As a
result, the Company reserved 3,750,000 shares of common stock for issuance upon
conversion of the Series C preferred stock. In addition, the rights, preferences
and privileges of the holders of Series A, B and C preferred stock were modified
as follows:

     - The mandatory redemption clause for holders of Series A and B preferred
       stock was annulled, and, accordingly, the amounts recorded for such stock
       were reclassified in the accompanying consolidated balance sheets as of
       March 31, 2000 from redeemable preferred stock to shareholders' equity
       (deficiency).

     - Dividends for Series C are noncumulative and payable only upon
       declaration by the Company's Board of Directors at a rate of $0.65444 per
       share per annum.

     - The holders of Series C preferred stock have voting rights equivalent to
       the number of shares of common stock into which it is convertible.

     - Each share of Series A, B and C preferred stock is convertible at any
       time into one share of common stock at the option of the holder, subject
       to adjustment to protect against dilution. The Company can be required to
       convert the preferred stock into common stock at the consent of not less
       than two-thirds of the outstanding Series A, B and C preferred
       stockholders, voting together as a single class. Each share of preferred
       stock automatically converts upon the closing of the sale of the
       Company's common stock in a public offering in which the aggregate cash
       proceeds, net of underwriting discounts and commissions, total at least
       $20,000,000 and the offering price is not less than $12.00 per share.

     - In the event of liquidation, dissolution or winding up of the Company,
       the holders of Series A, B and C preferred stock are entitled to receive
       $1.3333, $3.21 and $8.18 per share, respectively, as well as any declared
       but unpaid dividends on each share, prior to any distribution to the
       holders of common stock. Any remaining distributable assets of the
       Company would be distributed among the holders of Series A, B and C
       preferred stock and common stock on a pro rata basis, up to a total
       distribution of $4.00, $9.63 and $24.54 per share of Series A, B and C
       preferred stock, respectively, if such distribution takes place prior

        PERIOD FROM SEPTEMBER 9, 1997 (INCEPTION) TO DECEMBER 31, 1997,

       to the first anniversary of the purchase date of Series C preferred
       stock, and up to a total distribution of $6.6666, $16.05 and $40.90 per
       share of Series A, B and C preferred stock, respectively, if such
       distribution takes place on or after the first anniversary of the
       purchase date of the Series C preferred stock; after which any remaining
       assets are distributed solely to the holders of common stock.

     In January and February 2000, the Company sold 3,522,540 shares of Series C
preferred stock at $8.18 per share for gross proceeds of approximately $28.8
million. Pursuant to EITF Issue No. 98-5, the Company recognized a deemed
dividend of $1,677,667 on 205,094 shares of Series C preferred stock sold in
February 2000.

1997 Stock Option Plan Amendment

     In January and February 2000, the Board of Directors approved amendments to
the 1997 Stock Option Plan to increase the number of shares of common stock
reserved for issuance under the plan to an aggregate of 5,092,500.

2000 Nonstatutory Stock Option Plan

     In March 2000, the Company established a Nonstatutory Stock Option Plan,
which provides for the granting of stock options to employees and consultants as
nonstatutory stock options. The Company has reserved 1,000,000 shares of common
stock for issuance under the Plan. The term of each option shall be 10 years
from the date of grant, with the exercise price determined by the Administrator.
Options granted generally become exercisable at 20% per year over 5 years,
subject to repurchase with the repurchase right lapsing 20% per year over 5
years from the date the option is granted.

Acquisition of Sneaker Labs, Inc.

     On March 13, 2000, Octane acquired all of the outstanding capital stock of
Sneakerlabs, Inc. (Sneakerlabs), a developer of chat and web collaboration
software and services, for 1,049,992 shares of Octane common stock plus the
issuance of options to purchase approximately 69,000 shares of Octane common
stock at $3.00 per share. The terms of the agreement were accepted by both
parties concurrent with the closing of the acquisition on March 13, 2000. The
acquisition has been accounted for as a purchase and, accordingly, the Octane
shares and options issued to purchase Sneakerlabs have been valued at their
estimated fair value. Such Octane shares and options were valued at
approximately $101 million, based on a value of approximately $91 per share of
Octane stock. This per share value of Octane stock was derived principally by
reference to the closing share price of E.piphany stock on the date the proposed
merger with E.piphany, Inc. was publicly announced (March 15, 2000), adjusted by
the share exchange ratio to be used in the proposed merger between E.piphany and
Octane (See "Proposed Acquisition by E.piphany, Inc." above).

     The acquisition cost of approximately $101 million has been allocated to
acquired assets and assumed liabilities based on estimates of their fair values.

acquired from Sneakerlabs was less than $0.5 million, substantially all the
acquisition cost has been allocated to goodwill and other intangibles. The
allocation among the intangible assets has not been finalized; the expected
useful life of all intangibles, including goodwill, is three years.

     As of the acquisition date, Sneakerlabs had recently released its first two
products, iMeet and iServe, for commercial use. As of that date, Sneakerlabs had
no projects in process with respect to significant enhancements to those
products or with respect to new products. Accordingly, no amount of the purchase
price was assigned to in-process research and development.

     The results of operations of SneakerLabs are included in the accompanying
consolidated financial statements from the date of acquisition, and were not
significant during the period from March 14, 2000 through March 31, 2000.

          (b) Effect on Capital Stock. At the Effective Time, by virtue of the
     Merger and without any action on the part of the Sub, the Company or the
     Shareholders, each share of Company Common Stock issued and outstanding
     immediately prior to the Effective Time (other than any Dissenting Shares
     (as defined in Section 1.7) will be canceled and extinguished and be
     converted automatically into the right to receive, upon surrender of the
     certificate representing such share of Company Common Stock and upon the
     terms and subject to the conditions set forth below and throughout this
     Agreement, including, without limitation Sections 1.6(e) and (f) hereof and
     the escrow provisions set forth in Article VII and/or described in Section
     1.8(b) hereof, a fraction of a share of Parent Common Stock equal to the
     Stock Exchange Ratio.

          (c) Assumption of Company Stock Options, Warrants and Other Rights to
     Purchase Company Capital Stock.

             (i) At the Effective Time, under this Agreement, each Company
        Option will be assumed by Parent, and will continue to have, and be
        subject to, the same terms and conditions governing such Company Option
        immediately prior to the Effective Time (including, without limitation,
        any vesting schedule or repurchase rights), except that (i) each Company
        Option will be exercisable (or will become exercisable in accordance
        with its terms) for that number of whole shares of Parent Common Stock
        equal to the product of the number of shares of Company Common Stock
        that were issuable upon exercise of such Company Option immediately
        prior to the Effective Time multiplied by the Stock Exchange Ratio,
        rounded down to the nearest whole number of shares of Parent Common
        Stock, and (ii) the per share exercise price for the shares of Parent
        Common Stock issuable upon exercise of such assumed Company Option will
        be equal to the quotient determined by dividing the exercise price per
        share of Company Common Stock at which such Company Option was
        exercisable immediately prior to the Effective Time by the Stock
        Exchange Ratio, rounded up to the nearest whole cent. It is the
        intention of the parties that the assumed Company Options qualify to the
        maximum extent possible following the Effective Time as incentive stock
        options as defined in Section 422 of the Code to the extent such options
        qualified as incentive stock options prior to the Effective Time. Within
        thirty (30) days following the Effective Time, Parent will issue to each
        holder of an outstanding Company Option a notice describing the
        foregoing assumption of such Company Options by Parent.

             (ii) Prior to the Effective Time, the Company shall take all action
        necessary to effect the transactions anticipated by this Section 1.6(c)
        under all Company Option agreements and any other plan or arrangement of
        the Company.

          (d) Capital Stock of Sub. Each share of common stock of Sub issued and
     outstanding immediately prior to the Effective Time shall be converted into
     and exchanged for one validly issued, fully paid and nonassessable share of
     common stock of the Surviving Corporation. Each stock certificate of Sub
     evidencing ownership of any such shares shall continue to evidence
     ownership of such shares of capital stock of the Surviving Corporation.

          (e) Withholding Taxes. All Parent Common Stock issuable pursuant to
     Section 1.6 shall be subject to, and reduced by, the amount of any state,
     federal and foreign withholding taxes incurred by or applicable to a
     Shareholder (and that has not been previously paid by or on behalf of such
     Shareholder or the Company) in connection with the Merger, the acquisition
     of Company Capital Stock upon the exercise of Company Options, the
     acceleration of the vesting of any Company Option or any Company Capital
     Stock or the payment of a bonus in the form of Company Capital Stock.

<PAGE>   234

          (f) Fractional Shares. No fractional share of Parent Common Stock
     shall be issued in the Merger. In lieu thereof, any fractional share, after
     aggregating all shares held by a Shareholder, shall be rounded down to the
     nearest whole share of Parent Common Stock and to the extent required by
     Section 407 of the California Law, such Shareholder will be entitled to
     receive an amount of cash equal to the fractional shares to which such
     Shareholder would be entitled, multiplied by the Trading Price.

          (g) Adjustments to Stock Exchange Ratio. The Stock Exchange Ratio
     shall be adjusted to reflect fully the effect of any stock split, reverse
     split, dividend (including any dividend or distribution of cash, assets or
     securities convertible into Parent Capital Stock or Company Capital Stock),
     distribution, reorganization or recapitalization with respect to Parent
     Common Stock or Company Capital Stock occurring after the date hereof and
     prior to the Effective Time.

     1.7  Dissenting Shares.

          (a) Notwithstanding any provision of this Agreement to the contrary,
     any shares of Company Capital Stock held by a holder who has exercised and
     perfected appraisal rights for such shares in accordance with California
     Law and who, as of the Effective Time, has not effectively withdrawn or
     lost such dissenter's rights ("Dissenting Shares"), shall not be converted
     into or represent a right to receive the consideration for Company Capital
     Stock pursuant to Section 1.6, but the holder thereof shall only be
     entitled to such rights as are granted by California Law.

          (b) Notwithstanding the provisions of subsection (a), if any holder of
     Dissenting Shares shall effectively withdraw or lose (through failure to
     perfect or otherwise) his or her dissenter's rights, then, as of the later
     of Effective Time and the occurrence of such event, such holder's shares
     shall automatically be converted into and represent only the right to
     receive the consideration for Company Capital Stock as provided in Section
     1.6, without interest thereon, upon surrender of the certificate
     representing such shares.

          (c) The Company shall give Parent (i) prompt notice of any written
     demand for purchase received by the Company pursuant to the applicable
     provisions of California Law and (ii) the opportunity to participate in all
     negotiations and proceedings with respect to such demands. The Company
     shall not, except with the prior written consent of Parent, voluntarily
     make any payment with respect to any such demands or offer to settle or
     settle any such demands. To the extent that Parent or the Company makes any
     payment or payments in respect of any Dissenting Shares, Parent shall be
     entitled to recover under the terms of Article VII hereof the aggregate
     amount by which such payment or payments exceed the aggregate consideration
     that otherwise would have been payable in respect of such shares.

     1.8  Surrender of Certificates.

          (a) Exchange Agent. The Corporate Secretary of Parent or an
     institution selected by Parent and reasonably satisfactory to the Company
     shall serve as exchange agent (the "Exchange Agent") in the Merger.

          (b) Parent to Provide Shares. Promptly after the Effective Time,
     Parent shall make available to the Exchange Agent for exchange in
     accordance with this Article I, Certificates representing the shares of
     Parent Common Stock representing the Parent Common Stock Consideration (in
     the aggregate amount to be issued in the Merger); provided, however, that
     on behalf of the Shareholders, pursuant to Section 7.3 hereof, Parent shall
     deposit into an escrow account the number of shares of Parent Common Stock
     issued in respect of Company Common Stock held by such Shareholders
     pursuant to Section 1.6(b) to the Escrow Agent on behalf of

                                       -5-
<PAGE>   235

     the Shareholders equal to the product obtained by multiplying (x) ten
     percent (10%) by (y) the Parent Common Stock Consideration (the "Escrow
     Amount"). The portion of the Escrow Amount contributed on behalf of each
     Shareholder shall be in proportion to the aggregate number of shares of
     Parent Common Stock which such Shareholder would otherwise be entitled to
     receive in the Merger by virtue of ownership of outstanding shares of
     Company Common Stock.

          (c) Exchange Procedures. Concurrently with the distribution of the
     Proxy Statement/ Prospectus (as hereinafter defined), Parent shall cause
     the Exchange Agent to mail to each holder of record (as of such date) of a
     certificate or certificates (the "Certificates") which immediately prior to
     the Effective Time represented outstanding shares of Company Capital Stock
     whose shares were converted into the right to receive shares of Parent
     Common Stock pursuant to Section 1.6, (i) a letter of transmittal (which
     shall specify that delivery shall be effected, and risk of loss and title
     to the Certificates shall pass, only upon delivery of the Certificates to
     the Exchange Agent and shall be in such form and have such other provisions
     as Parent may reasonably specify) and (ii) instructions for use in
     effecting the surrender of the Certificates in exchange for certificates
     representing shares of Parent Common Stock. Upon surrender of Certificates
     for cancellation to the Exchange Agent or to such other agent or agents as
     may be appointed by Parent, together with such letter of transmittal, duly
     completed and validly executed in accordance with the instructions thereto,
     the holders of such Certificates shall be entitled to receive in exchange
     therefor certificates representing the number of whole shares of Parent
     Common Stock, and the Certificates so surrendered shall forthwith be
     canceled. Until so surrendered, outstanding Certificates will be deemed
     from and after the Effective Time, for all corporate purposes, subject to
     Section 1.8(d) as to the payment of dividends, to evidence the ownership of
     the number of full shares of Parent Common Stock into which such shares of
     Company Capital Stock shall have been so converted and the right to receive
     any dividends or distributions payable pursuant to Section 1.8(d).

          (d) Distributions With Respect to Unexchanged Shares. No dividends or
     other distributions declared or made after the date of this Agreement with
     respect to Parent Common Stock with a record date after the Effective Time
     will be paid to the holders of any unsurrendered Certificates with respect
     to the shares of Parent Common Stock represented thereby until the holders
     of record of such Certificates shall surrender such Certificates. Subject
     to applicable law, following surrender of any such Certificates, the
     Exchange Agent shall deliver to the record holders thereof, without
     interest, certificates representing whole shares of Parent Common Stock
     issued in exchange therefor and the amount of any such dividends or other
     distributions with a record date after the Effective Time payable with
     respect to such whole shares of Parent Common Stock. No interest shall
     accrue or be owed to a Shareholder with respect to any amounts which the
     Shareholder has the right to receive.

          (e) Transfers of Ownership. If certificates for shares of Parent
     Common Stock are to be issued in a name other than that in which the
     Certificates surrendered in exchange therefor are registered, it will be a
     condition of the issuance thereof that the Certificates so surrendered will
     be properly endorsed and otherwise in proper form for transfer and that the
     persons requesting such exchange will have paid to Parent or any agent
     designated by it any transfer or other taxes required by reason of the
     issuance of certificates for shares of Parent Common Stock in any name
     other than that of the registered holder of the Certificates surrendered,
     or established to the satisfaction of Parent or any agent designated by it
     that such tax has been paid or is not payable.

          (f) No Liability. Notwithstanding anything to the contrary in this
     Section 1.8, none of the Exchange Agent, the Surviving Corporation or any
     party hereto shall be liable to a holder of

                                       -6-
<PAGE>   236

     shares of Company Capital Stock for any amount properly paid to a public
     official pursuant to any applicable abandoned property, escheat or similar
     law.

     1.9  No Further Ownership Rights in Company Capital Stock. All
consideration paid in respect of the surrender for exchange of shares of Company
Capital Stock in accordance with the terms hereof, shall be deemed to be full
satisfaction of all rights pertaining to such shares of Company Capital Stock,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Company Capital Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article I.

     1.10  Lost, Stolen or Destroyed Certificates. In the event any Certificates
evidencing shares of Company Capital Stock shall have been lost, stolen or
destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or
destroyed certificates, upon the making of an affidavit of that fact by the
holder thereof, such shares of Parent Common Stock as may be required pursuant
to Section 1.8; provided, however, that Parent may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed certificates to deliver a bond in such sum as it may
reasonably direct against any claim that may be made against Parent or the
Exchange Agent with respect to the certificates alleged to have been lost,
stolen or destroyed.

     1.11  Taking of Necessary Action; Further Action. If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company, Parent and Sub, the officers and directors of the
Company, Parent and Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.

     1.12  Tax and Accounting Consequences. It is intended by the parties hereto
that the Merger shall constitute a reorganization within the meaning of Section
368 of the Internal Revenue Code of 1986, as amended (the "Code") and the
parties hereby adopt this Agreement as a plan of reorganization. Each party has
consulted with its own tax advisors and accountants with respect to the tax and
accounting consequences, respectively, of the Merger.

exceptions as are specifically disclosed in the disclosure schedule (referencing
the appropriate Section and paragraph numbers) supplied by the Company to Parent
and attached hereto as Exhibit C (the "Disclosure Schedule"), that on the date
hereof and as of the Effective Time as though made at the Effective Time as
follows:

     2.1  Organization of the Company. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
California. The Company has the corporate power to own its properties and to
carry on its business as now being conducted. The Company is duly qualified to
do business and in good standing as a foreign corporation in each jurisdiction
in which the failure to be so qualified could have a Company Material Adverse
Effect. Each of the Subsidiaries (as defined in Section 2.2 below) of the
Company is duly organized, validly existing and in good standing under the laws
of the jurisdiction of its formation and has the corporate or other applicable
power to own its properties and to carry on its business as now being conducted.
Each of the Subsidiaries is duly qualified to do business and in good standing
in each jurisdiction

                                       -7-
<PAGE>   237

outside of the jurisdiction of its formation in which the failure to be so
qualified would have a Company Material Adverse effect. For all purposes of this
Agreement, the term "Company Material Adverse Effect" means any change, event or
effect that is materially adverse to the business, assets (including intangible
assets), condition (financial or otherwise), results of operations or prospects
of the Company and its subsidiaries, taken as a whole; provided, however, that a
change, event or effect resulting directly from the announcement of this
Agreement and the Merger shall not be deemed to have a Company Material Adverse
Effect. The Company has delivered a true and correct copy of its Articles of
Incorporation and Bylaws, each as amended to date, to Parent. Section 2.1 of the
Disclosure Schedule lists the directors and officers of the Company. The
operations now being conducted by the Company have not been conducted under any
other name.

     2.2  Subsidiaries. Except as set forth in Section 2.2 of the Disclosure
Schedule, the Company does not have, and has never had, any subsidiaries and
does not otherwise own, and has not otherwise owned, any shares in the capital
of or any interest in, or control of, directly or indirectly, any corporation,
partnership, association, joint venture or other business entity. The entities
set forth in Section 2.2 of the Disclosure Schedule are hereinafter occasionally
referred to individually as a "Subsidiary" and, collectively, as the
"Subsidiaries." Section 2.2 of the Disclosure Schedule also sets forth or
references the form and percentage interest of the Company in the Subsidiaries
and, to the extent that a Subsidiary set forth thereon is not wholly owned by
the Company, lists the other person, persons, entity or entities who have an
interest in such Subsidiary and references the percentage of such interest.

     2.3  Company Capital Structure.

          (a) The authorized Company Capital Stock consists of 30,000,000 shares
     of authorized Company Common Stock, with no par value, of which 9,707,353
     shares are issued and outstanding as of the date hereof, and 13,350,000
     shares of Preferred Stock, with no par value, of which 4,750,000 shares are
     designated Series A Preferred Stock, of which 4,650,000 are issued and
     outstanding as of the date hereof 4,850,000 shares are designated Series B

     hereof and 3,750,000 shares are designated Series C Preferred Stock, of

     share of Company Series A Preferred Stock is convertible into 1 share of
     Company Common Stock. Each share of Company Series B Preferred Stock is
     convertible into 1 share of Company Common Stock. Each share of Company
     Series C Preferred Stock is convertible into 1 share of Company Common

pursuant to resolution of each such entity's Board of Directors (the form and
substance of which resolutions shall be subject to review and reasonable
approval of Parent), effective as of the day immediately preceding the Closing
Date.

     and Parent will notify the other promptly upon the receipt of any comments
     from the SEC or its staff and of any request by the SEC or its staff or any

     event occurs which is required to be set forth in an amendment or
     supplement to the Proxy Statement/Prospectus, the S-4 or any Other Filing,
     the Company or Parent, as the case may be, will promptly inform the other

     California Law and its Articles of Incorporation and Bylaws to convene a
     special meeting of its Shareholders to be held on the twenty-first day
     after the mailing of the Proxy Statement/Prospectus to the Shareholders for
     the purpose of voting upon this Agreement and the Merger. The Company will
     use commercially reasonable efforts to solicit from its shareholders
     proxies in favor of the adoption and approval of this Agreement and the
     approval of the Merger and will take all other action necessary or
     advisable to secure the vote or consent of its shareholders required to
     obtain such approvals. The materials submitted to the Company's
     Shareholders shall have been subject to review and approval by Parent and

     its stockholders for the purpose of approving the issuance of the Parent
     Common Stock consideration in the Merger. Parent will use commercially
     reasonable efforts to solicit from its stockholders proxies in favor of the

          SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

     7.1  Survival of Representations and Warranties. The Company's
representations and warranties in this Agreement shall survive the Merger and
shall continue until the date that is twelve (12) months after the Closing Date
(the "Escrow Termination Date"). All of the Parent's and Sub's representations
and warranties in this Agreement shall survive the Merger and shall continue
until the date that is twelve (12) months after the Closing Date.

     7.2  Indemnification. The Company agrees to indemnify and hold Parent and
its officers, directors and affiliates harmless against all claims, losses,
liabilities, damages, deficiencies, costs and expenses, including reasonable
attorneys' fees and expenses of investigation and defense (hereinafter
individually a "Loss" and collectively "Losses") incurred by Parent, its
officers, directors, or affiliates (including the Surviving Corporation)
directly or indirectly as a result of (a) any inaccuracy or breach of a
representation or warranty of the Company contained in this Agreement or any
Related Agreements (b) any failure by the Company to perform or comply with any
covenant contained in this Agreement or any Related Agreements or (c) the Third
Party Expenses of the Company exceeding the greater of the Estimated Third Party
Expenses or $500,000. The Shareholders shall not
                                      -39-
<PAGE>   269

have any right of indemnification or contribution from the Company with respect
to any Loss claimed by an indemnified party after the Effective Time.
Notwithstanding the foregoing, the Company shall not have any liability under
subsections (a) or (b) of this Section 7.2, unless and until the aggregate
Losses for which indemnification is sought (aggregating all of the claims
against the Company under subsections (a) or (b)) exceed $1,750,000 (the
"Basket"), in which case the full amount of such Losses (including the
$1,750,000) shall be subject to indemnification; provided, however, that in the
event that aggregate Losses attributable to breaches of Section 2.13 ("Section
2.13 Losses") exceed $500,000 prior to such time as total aggregate Losses
exceed the Basket, then the Company shall have liability to Parent to the extent
of such Section 2.13 Losses (including the $500,000), and provided, further,
that in the event the Company has liability to Parent for Section 2.13 Losses
pursuant to the foregoing proviso, then the Basket shall be reduced to
$1,250,000 for Losses other than Section 2.13 Losses.

     7.3  Exclusive Contractual Remedy. Except in the case of fraud or willful
misconduct, the rights of the Parent to make claims upon the Escrow Fund in
accordance with this Section 7 shall be the sole and exclusive remedy of Parent,
the Surviving Corporation and any other Indemnified Persons after the Closing
with respect to any representation, warranty, covenant or agreement made by
Company under this Agreement and no Shareholder of Company shall have any
personal liability to Parent, the Surviving Corporation or any other Indemnified
Persons after the Closing in connection with the Merger.

     7.4  Escrow Arrangements.

          (a) Escrow Fund. As security for the indemnity provided for in Section
     7.2 hereof and by virtue of this Agreement and the Merger Agreement, the
     Company and the Shareholders will be deemed to have received and deposited
     with the Escrow Agent (as defined below) the Escrow Amount (plus any
     additional shares as may be issued upon any stock split, stock dividend or
     recapitalization effected by Parent after the Effective Time with respect
     to the Escrow Amount) without any act of the Company or any Shareholders.
     As soon as practicable after the Effective Time, the Escrow Amount, without
     any act of any Shareholders, will be deposited with U.S. Bank Trust N.A.
     (or other institution acceptable to Parent and the Securityholder Agent (as
     defined in Section 7.4(g) below)) as Escrow Agent (the "Escrow Agent"),
     such deposit to constitute an escrow fund (the "Escrow Fund") to be
     governed by the terms set forth herein. The Escrow Agent may execute this
     Agreement following the date hereof and prior to the Effective Time, and
     such latter execution shall not affect the binding nature of this Agreement
     as of the date hereof among the signatories hereto.

          (b) Escrow Period; Distribution upon Termination of Escrow
     Periods. Subject to the following requirements, the Escrow Fund shall be in
     existence immediately following the Effective Time and shall terminate at
     5:00 p.m., Pacific time, on the Escrow Termination Date (the "Escrow
     Period"); provided that, the Escrow Period shall not terminate with respect
     to such remaining portion of the Escrow Fund (or some portion thereof) that
     in the reasonable judgement of Parent, subject to the objection of the
     Securityholder Agent (as defined below) and the subsequent arbitration of
     the matter in the manner provided in Section 7.4(f) hereof, is necessary to
     satisfy (i) any then pending unsatisfied claims specified in any Officer's
     Certificate delivered to the Escrow Agent prior to the termination of the
     Escrow Period and (ii) any unsatisfied claims specified in any Officer's
     Certificate delivered to the Escrow Agent prior to three days after the
     termination of the Escrow Period with respect to facts and circumstances
     existing prior to the termination of such Escrow Period (including, in the
     case of both (i) and (ii) above, an Officer's Certificate delivered to the
     Escrow Agent that states that the Parent reasonably believes that it may
     have a claim against the Escrow Fund and describing the grounds for such
     claim). As soon as all such claims have been resolved, the Escrow Agent
     shall deliver

                                      -40-
<PAGE>   270

     to the Shareholders the remaining portion of the Escrow Fund not required
     to satisfy such claims. Deliveries of Escrow Amounts to the Shareholders
     pursuant to this Section 7.4(b) shall be made in proportion to their
     respective original contributions to the Escrow Fund.

          (c) Protection of Escrow Fund.

             (i) The Escrow Agent shall hold and safeguard the Escrow Fund
        during the Escrow Period, shall treat such fund as a trust fund in
        accordance with the terms of this Agreement and not as the property of
        Parent and shall hold and dispose of the Escrow Fund only in accordance
        with the terms hereof.

             (ii) Any shares of Parent Common Stock or other equity securities
        issued or distributed by Parent (including shares issued upon a stock
        split) ("New Shares") in respect of Parent Common Stock in the Escrow
        Fund which have not been released from the Escrow Fund shall be added to
        the Escrow Fund and become a part thereof. New Shares issued in respect
        of shares of Parent Common Stock which have been released from the
        Escrow Fund shall not be added to the Escrow Fund but shall be
        distributed to the record holders thereof. Cash dividends on Parent
        Common Stock, if any, shall not be added to the Escrow Fund but shall be
        distributed to the record holders thereof.

             (iii) Each Shareholder shall have voting rights and the right to
        distributions of dividends with respect to the shares of Parent Common
        Stock contributed to the Escrow Fund by such Shareholders (and on any
        voting securities added to the Escrow Fund in respect of such shares of
        Parent Common Stock).

          (d) Claims Upon Escrow Fund.

             (i) Upon receipt by the Escrow Agent at any time on or before three
        days after the last day of the Escrow Period of a certificate signed by
        any officer of Parent (an "Officer's Certificate"): (A) stating that
        Parent has paid Losses, (B) specifying in reasonable detail the
        individual items of Losses included in the amount so stated, the date
        each such item was paid, and the nature of the misrepresentations,
        breach of warranty or covenant to which such items are related and (C)
        specifying the number of Escrow Shares necessary to satisfy such claim,
        the Escrow Agent shall, subject to the provisions of Section 7.4(e),
        deliver to Parent out of the Escrow Fund as promptly as practicable,
        shares of Parent Common Stock held in the Escrow Fund in an amount equal
        to such Losses.

             (ii) For the purposes of determining the number of shares of Parent
        Common Stock to be delivered to Parent out of the Escrow Fund as
        indemnity pursuant to Section 7.4(b) and 7.4(d)(i) hereof, the shares of
        Parent Common Stock shall be valued at the Trading Price.

          (e) Objections to Claims. At the time of delivery of any Officer's
     Certificate to the Escrow Agent, a duplicate copy of such certificate shall
     be delivered to the Securityholder Agent and for a period of thirty (30)
     days after such delivery, the Escrow Agent shall make no delivery to Parent
     of any Escrow Amounts pursuant to Section 7.4(d) hereof unless the Escrow
     Agent shall have received written authorization from the Securityholder
     Agent to make such delivery. After the expiration of such thirty (30) day
     period, the Escrow Agent shall make delivery of shares of Parent Common
     Stock from the Escrow Fund in accordance with Section 7.4(d) hereof,
     provided that no such payment or delivery may be made if the Securityholder
     Agent shall object in a written statement to the claim made in the
     Officer's Certificate, and such statement shall have been delivered to the
     Escrow Agent prior to the expiration of such thirty (30) day period.

                                      -41-
<PAGE>   271

          (f) Resolution of Conflicts; Arbitration.

             (i) In case the Securityholder Agent shall so object in writing to
        any claim or claims made in any Officer's Certificate, the
        Securityholder Agent and Parent shall attempt in good faith to agree
        upon the rights of the respective parties with respect to each of such
        claims. If the Securityholder Agent and Parent should so agree, a
        memorandum setting forth such agreement shall be prepared and signed by
        both parties and shall be furnished to the Escrow Agent. The Escrow
        Agent shall be entitled to rely on any such memorandum and distribute
        shares of Parent Common Stock from the Escrow Fund in accordance with
        the terms thereof.

             (ii) If no such agreement can be reached after good faith
        negotiation, either Parent or the Securityholder Agent may demand
        arbitration of the matter unless the amount of the damage or loss is at
        issue in pending litigation with a third party, in which event
        arbitration shall not be commenced until such amount is ascertained or
        both parties agree to arbitration; and in either such event the matter
        shall be settled by arbitration conducted by one arbitrator mutually
        agreeable to Parent and the Securityholder Agent. In the event that
        within forty-five (45) days after submission of any dispute to
        arbitration, Parent and the Securityholder Agent cannot mutually agree
        on one arbitrator, Parent and the Securityholder Agent shall each select
        one arbitrator, and the two arbitrators so selected shall select a third
        arbitrator. The arbitrator or arbitrators, as the case may be, shall set
        a limited time period and establish procedures designed to reduce the
        cost and time for discovery while allowing the parties an opportunity,
        adequate in the sole judgement of the arbitrator or majority of the
        three arbitrators, as the case may be, to discover relevant information
        from the opposing parties about the subject matter of the dispute. The
        arbitrator or a majority of the three arbitrators, as the case may be,
        shall rule upon motions to compel or limit discovery and shall have the
        authority to impose sanctions, including attorneys' fees and costs, to
        the extent as a court of competent law or equity, should the arbitrator
        or a majority of the three arbitrators, as the case may be, determine
        that discovery was sought without substantial justification or that
        discovery was refused or objected to without substantial justification.
        The decision of a the arbitrator or a majority of the three arbitrators,
        as the case may be, as to the validity and amount of any claim in such
        Officer's Certificate shall be binding and conclusive upon the parties
        to this Agreement, and notwithstanding anything in Section 7.4(e)
        hereof, the Escrow Agent shall be entitled to act in accordance with
        such decision and make or withhold payments out of the Escrow Fund in
        accordance therewith. Such decision shall be written and shall be
        supported by written findings of fact and conclusions which shall set
        forth the award, judgment, decree or order awarded by the arbitrator(s).

             (iii) Judgment upon any award rendered by the arbitrator(s) may be
        entered in any court having jurisdiction. Any such arbitration shall be
        held in San Mateo County, California under the rules then in effect of
        the American Arbitration Association. The arbitrator(s) shall determine
        how all expenses relating to the arbitration shall be paid, including
        without limitation, the respective expenses of each party, the fees of
        each arbitrator and the administrative fee of the American Arbitration
        Association.

          (g) Securityholder Agent of the Shareholders; Power of Attorney.

             (i) In the event that the Merger is approved, effective upon such
        vote, and without further act of any Shareholders, David N. Strohm shall
        be appointed as agent and attorney-in-fact (the "Securityholder Agent")
        for each Shareholder of the Company, for and on behalf of Shareholders,
        to give and receive notices and communications, to authorize

                                      -42-
<PAGE>   272

        delivery to Parent of shares of Parent Common Stock from the Escrow Fund
        in satisfaction of claims by Parent, to object to such deliveries, to
        agree to, negotiate, enter into settlements and compromises of, and
        demand arbitration and comply with orders of courts and awards of
        arbitrators with respect to such claims, and to take all actions
        necessary or appropriate in the judgment of Securityholder Agent for the
        accomplishment of the foregoing. Such agency may be changed by the
        Shareholders from time to time upon not less than thirty (30) days prior
        written notice to Parent; provided that the Securityholder Agent may not
        be removed unless holders of a majority interest of the Escrow Fund
        agree to such removal and to the identity of the substituted agent. No
        bond shall be required of the Securityholder Agent, and the
        Securityholder Agent shall not receive compensation for his or her
        services, but shall be entitled to reimbursement of reasonable and
        documented out-of-pocket expenses (including reasonable legal fees)
        incurred in carrying out the Securityholder Agent's duties as such out
        of the Escrow Fund to the extent available. Notices or communications to
        or from the Securityholder Agent shall constitute notice to or from each
        of the Shareholders. The Securityholder Agent may execute this Agreement
        following the date hereof and prior to the Effective Time, and such
        latter execution shall not affect the binding nature of this Agreement
        as of the date hereof among the signatories hereto.

             (ii) The Securityholder Agent shall not be liable for any act done
        or omitted hereunder as Securityholder Agent while acting in good faith
        and in the exercise of reasonable judgment. The Shareholders on whose
        behalf the Escrow Amount was contributed to the Escrow Fund shall
        severally indemnify the Securityholder Agent and hold the Securityholder
        Agent harmless against any loss, liability or expense incurred without
        negligence or bad faith on the part of the Securityholder Agent and
        arising out of or in connection with the acceptance or administration of
        the Securityholder Agent's duties hereunder, including the reasonable
        fees and expenses of any legal counsel retained by the Securityholder
        Agent.

          (h) Actions of the Securityholder Agent. A decision, act, consent or
     instruction of the Securityholder Agent shall constitute a decision of all
     the Shareholders for whom a portion of the Escrow Amount otherwise issuable
     to them are deposited in the Escrow Fund and shall be final, binding and
     conclusive upon each of such Shareholders, and the Escrow Agent and Parent
     may rely upon any such decision, act, consent or instruction of the
     Securityholder Agent as being the decision, act, consent or instruction of
     each and every such Shareholder. The Escrow Agent and Parent are hereby
     relieved from any liability to any person for any acts done by them in
     accordance with such decision, act, consent or instruction of the
     Securityholder Agent.

          (i) Third-Party Claims. In the event Parent becomes aware of a
     third-party claim which Parent believes may result in a demand against the
     Escrow Fund, Parent shall notify the Securityholder Agent of such claim,
     and the Securityholder Agent and the Shareholders of the Company shall be
     entitled, at their expense, to participate in any defense of such claim.
     Parent shall have the right in its sole discretion to settle any such
     claim; provided, however, that except with the consent of the
     Securityholder Agent, no settlement of any such claim with third-party
     claimants shall be determinative of the amount of any claim against the
     Escrow Fund. In the event that the Securityholder Agent has consented to
     any such settlement, the Securityholder Agent shall have no power or
     authority to object under any provision of this Article VII to the amount
     of any claim by Parent against the Escrow Fund with respect to such
     settlement.

                                      -43-
<PAGE>   273

          (j) Escrow Agent's Duties.

             (i) The Escrow Agent shall be obligated only for the performance of
        such duties as are specifically set forth herein, and as set forth in
        any additional written escrow instructions which the Escrow Agent may
        receive after the date of this Agreement which are signed by an officer
        of Parent and the Securityholder Agent, and may rely and shall be
        protected in relying or refraining from acting on any instrument
        reasonably believed to be genuine and to have been signed or presented
        by the proper party or parties. The Escrow Agent shall not be liable for
        any act done or omitted hereunder as Escrow Agent while acting in good
        faith and in the exercise of reasonable judgment, and any act done or
        omitted pursuant to the advice of counsel shall be conclusive evidence
        of such good faith.

             (ii) The Escrow Agent is hereby expressly authorized to disregard
        any and all warnings given by any of the parties hereto or by any other
        person, excepting only orders or process of courts of law, and is hereby
        expressly authorized to comply with and obey orders, judgments or
        decrees of any court. In case the Escrow Agent obeys or complies with
        any such order, judgment or decree of any court, the Escrow Agent shall
        not be liable to any of the parties hereto or to any other person by
        reason of such compliance, notwithstanding any such order, judgment or
        decree being subsequently reversed, modified, annulled, set aside,
        vacated or found to have been entered without jurisdiction.

             (iii) The Escrow Agent shall not be liable in any respect on
        account of the identity, authority or rights of the parties executing or
        delivering or purporting to execute or deliver this Agreement or any
        documents or papers deposited or called for hereunder.

             (iv) The Escrow Agent shall not be liable for the expiration of any
        rights under any statute of limitations with respect to this Agreement
        or any documents deposited with the Escrow Agent.

             (v) In performing any duties under the Agreement, the Escrow Agent
        shall not be liable to any party for damages, losses, or expenses,
        except for negligence or willful misconduct on the part of the Escrow
        Agent. The Escrow Agent shall not incur any such liability for (A) any
        act or failure to act made or omitted in good faith, or (B) any action
        taken or omitted in reliance upon any instrument, including any written
        statement of affidavit provided for in this 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 representative authority. In addition, the
        Escrow Agent may consult with the legal counsel in connection with
        Escrow Agent's duties under this Agreement and shall be fully protected
        in any act taken, suffered, or permitted by him/her 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 Agreement.

             (vi) If any controversy arises between the parties to this
        Agreement, or with any other party, concerning the subject matter of
        this Agreement, its terms or conditions, the Escrow Agent will not be
        required to determine the controversy or to take any action regarding
        it. The Escrow Agent may hold all documents and shares of Parent Common
        Stock and may wait for settlement of any such controversy by final
        appropriate legal proceedings or other means as, in the Escrow Agent's
        discretion, the Escrow Agent may be required, despite what may be set
        forth elsewhere in this Agreement. In such event, the Escrow Agent will
        not be liable for damages.

             Furthermore, the Escrow Agent may at its option, file an action of
        interpleader requiring the parties to answer and litigate any claims and
        rights among themselves. The Escrow Agent is authorized to deposit with
        the clerk of the court all documents and shares of Parent Common Stock
        held in escrow, except all cost, expenses, charges and reasonable
        attorney fees incurred by the Escrow Agent due to the interpleader
        action and which the parties jointly and severally agree to pay. Upon
        initiating such action, the Escrow Agent shall be fully released and
        discharged of and from all obligations and liability imposed by the
        terms of this Agreement.

             (vii) The parties and their respective successors and assigns agree
        jointly and severally to indemnify and hold Escrow Agent harmless
        against any and all losses, claims, damages, liabilities, and expenses,
        including reasonable costs of investigation, counsel fees, including
        allocated costs of in-house counsel and disbursements that may be
        imposed on Escrow Agent or incurred by Escrow Agent in connection with
        the performance of his/her duties under this Agreement, including but
        not limited to any litigation arising from this Agreement or involving
        its subject matter other than arising out of its negligence or willful
        misconduct provided, however, that the Shareholder's maximum liability
        hereunder shall not exceed the amounts then available from the Escrow
        Fund.

             (viii) The Escrow Agent may resign at any time upon giving at least
        thirty (30) days written notice to Parent and the Securityholder Agent;
        provided, however, that no such resignation shall become effective until
        the appointment of a successor escrow agent which shall be accomplished
        as follows: the parties shall use their best efforts to mutually agree
        on a successor escrow agent within thirty (30) days after receiving such
        notice. If the parties fail to agree upon a successor escrow agent
        within such time, the Escrow Agent shall have the right to appoint a
        successor escrow agent authorized to do business in the state of
        California. The successor escrow agent shall execute and deliver an
        instrument accepting such appointment and it shall, without further
        acts, be vested with all the estates, properties, rights, powers, and
        duties of the predecessor escrow agent as if originally named as escrow
        agent. Upon appointment of a successor escrow agent, the Escrow Agent
        shall be discharged from any further duties and liability under this
        Agreement.

          (k) Fees. All fees of the Escrow Agent for performance of its duties
     hereunder shall be paid by Parent in accordance with the standard fee
     schedule of the Escrow Agent. It is understood that the fees and usual
     charges agreed upon for services of the Escrow Agent shall be considered
     compensation for ordinary services as contemplated by this Agreement. In
     the event that the conditions of this Agreement are not promptly fulfilled,
     or if the Escrow Agent renders any service not provided for in this
     Agreement, or if the parties request a substantial modification of its
     terms, or if any controversy arises, or if the Escrow Agent is made a party
     to, or intervenes in, any litigation pertaining to the Escrow Fund or its
     subject matter, the Escrow Agent shall be reasonably compensated for such
     extraordinary services and reimbursed for all costs, attorney's fees,
     including allocated costs of in-house counsel, and expenses occasioned by
     such default, delay, controversy or litigation. The Parent promises to pay
     these sums upon demand.

otherwise) arising out of or relating to this agreement or the actions of
Parent, Company or Sub in the negotiation, administration, performance and
enforcement hereof.

represented by counsel during the negotiation and execution of this Agreement
and, therefor, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

enforcement of any provision of this Agreement is brought by any party hereto,

     (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or

shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.

     (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

     (1) Which were not immediately prior to the reorganization or short-form
merger either (A) listed on any national securities exchange certified by the
Commissioner of Corporations under subdivision (o) of Section 25100 or (B)

Federal Reserve System, and the notice of meeting of shareholders to act upon
the reorganization summarizes this section and Sections 1301, 1302, 1303 and
1304; provided, however, that this provision does not apply to any shares with
respect to which there exists any restriction on transfer imposed by the
corporation or by any law or regulation; and provided, further, that this
provision does not apply to any class of shares described in subparagraph (A) or
(B) if demands for payment are filed with respect to 5 percent or more of the
outstanding shares of that class.

     (2) Which were outstanding on the date for the determination of
shareholders entitled to vote on the reorganization and (A) were not voted in
favor of the reorganization or, (B) if described in subparagraph (A) or (B) of
paragraph (1) (without regard to the provisos in that paragraph), were voted
against the reorganization, or which were held of record on the effective date
of a short-form merger; provided, however, that subparagraph (A) rather than
subparagraph (B) of this paragraph applies in any case where the approval
required by Section 1201 is sought by written consent rather than at a meeting.

     (3) Which the dissenting shareholder has demanded that the corporation
purchase at their fair market value, in accordance with Section 1301.

     (4) Which the dissenting shareholder has submitted for endorsement, in
accordance with Section 1302.

     (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

     1301 DEMAND FOR PURCHASE.

     (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such

                                        1
<PAGE>   293

shareholder a notice of the approval of the reorganization by its outstanding
shares (Section 152) within 10 days after the date of such approval, accompanied
by a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of
the price determined by the corporation to represent the fair market value of
the dissenting shares, and a brief description of the procedure to be followed
if the shareholder desires to exercise the shareholder's right under such
sections. The statement of price constitutes an offer by the corporation to
purchase at the price stated any dissenting shares as defined in subdivision (b)
of Section 1300, unless they lose their status as dissenting shares under
Section 1309.

     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

     (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

     1302 ENDORSEMENT OF SHARES.

     Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.

     1303 AGREED PRICE -- TIME OF PAYMENT.

     (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

     (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in

                                        2
<PAGE>   294

the case of certificated securities, subject to surrender of the certificates
therefor, unless provided otherwise by agreement.

     1304 DISSENTER'S ACTION TO ENFORCE PAYMENT.

     (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of the
shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

     (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.

     (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

     1305 APPRAISERS' REPORT -- PAYMENT -- COSTS.

     (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.

     (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

     (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.

     (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

     (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

<PAGE>   295

     1306 DISSENTING SHAREHOLDERS' STATUS AS CREDITOR.

     To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

     1307 DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.

     Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.

     1308 CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING SHAREHOLDERS.

     Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder may not withdraw a demand for payment unless the corporation
consents thereto.

     1309 TERMINATION OF DISSENTING SHAREHOLDER STATUS.

     Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:

     (a) The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

     (b) The shares are transferred prior to their submission for endorsement in
accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.

     (c) The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

     (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

     1310  SUSPENSION OF PROCEEDINGS FOR PAYMENT PENDING LITIGATION.

     If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.

     1311  EXEMPT SHARES.

     This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

     1312  ATTACKING VALIDITY OF REORGANIZATION OR MERGER.

     (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.

     (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

             [LETTERHEAD OF CREDIT SUISSE FIRST BOSTON CORPORATION]

March 14, 2000

Board of Directors
E.piphany, Inc.
1900 South Norfolk Street, Suite 310
San Mateo, California 94403

Members of the Board:

You have asked us to advise you with respect to the fairness, from a financial
point of view, to E.piphany, Inc. ("E.piphany") of the Consideration (as defined
below) set forth in the Agreement and Plan of Reorganization, dated as of March
14, 2000 (the "Agreement"), by and among E.piphany, Orchid Acquisition
Corporation, a wholly owned subsidiary of E.piphany ("Merger Sub"), and Octane
Software, Inc. ("Octane"). The Agreement provides for, among other things, the
merger of Merger Sub with and into Octane (the "Merger") pursuant to which
E.piphany will acquire all of the outstanding shares of capital stock of Octane
and assume all obligations relating to outstanding options, warrants and other
rights to purchase capital stock of Octane, in exchange for aggregate
consideration consisting of that number of shares of the common stock, par value
$0.0001 per share, of E.piphany (the "E.piphany Common Stock") and options,
warrants and other rights to purchase E.piphany Common Stock equal to (i)
12,793,510 less (ii) an amount equal to (a) the amount by which the estimated
fees and expenses incurred by Octane in connection with the Merger exceed
$1,500,000 divided by (b) $192.85 (the "Consideration").

In arriving at our opinion, we have reviewed the Agreement and certain related
documents, certain publicly available business and financial information
relating to E.piphany and certain available business and financial information
relating to Octane. We have also reviewed certain other information relating to
E.piphany and Octane, including financial forecasts, provided to or discussed
with us by E.piphany and Octane, and have met with the managements of E.piphany
and Octane to discuss the businesses and prospects of E.piphany and Octane,
including the ability to integrate the businesses of E.piphany and Octane. We
have also considered certain financial and stock market data of E.piphany and
certain financial data of Octane, and we have compared those data with similar
data for publicly held companies in businesses similar to E.piphany and Octane,
and we have considered, to the extent publicly available, the financial terms of
certain other business combinations and other transactions which have recently
been effected. We also considered such other information, financial studies,
analyses and investigations and financial, economic and market criteria which we
deemed relevant.

In connection with our review, we have not assumed any responsibility for
independent verification of any of the foregoing information and have relied on
such information being complete and accurate in all material respects. With
respect to the financial forecasts, we have been advised, and have assumed, that
the management of E.piphany has reviewed publicly available financial forecasts
for E.piphany and that such publicly available forecasts represent reasonable
estimates and judgments as to the future financial performance of E.piphany, and
that the financial forecasts for Octane have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
managements of E.piphany and Octane as to the future financial performance of
Octane. In addition, we have relied upon, without independent verification, the
assessments of the managements
<PAGE>   298
Board of Directors
E.piphany, Inc.

Page  2

of E.piphany and Octane as to (i) their ability to retain key employees of
Octane, (ii) the strategic benefits anticipated by the managements of E.piphany
and Octane to result from the Merger, (iii) Octane's existing technology and
products and the validity of, and risks associated with, Octane's future
technology and products and (iv) the ability to integrate the businesses of
E.piphany and Octane. We also have assumed, with your consent, that the Merger
will be treated as a tax-free reorganization for federal income tax purposes. We
have not been requested to make, and have not made, an independent evaluation or
appraisal of the assets or liabilities (contingent or otherwise) of E.piphany or
Octane, nor have we been furnished with any such evaluations or appraisals. Our
opinion is necessarily based upon information available to us, and financial,
economic, market and other conditions as they exist and can be evaluated, on the
date hereof. We are not expressing any opinion as to what the value of the
E.piphany Common Stock actually will be when issued pursuant to the Merger or
the prices at which the E.piphany Common Stock will trade subsequent to the
Merger.

We have acted as financial advisor to E.piphany in connection with the Merger
and will receive a fee for our services, a significant portion of which is
contingent upon the consummation of the Merger. We will also receive a fee upon
delivery of this opinion. We and our affiliates have in the past provided and
are currently providing financial services to E.piphany unrelated to the
proposed Merger, for which services we have received and in the future may
receive compensation. In the ordinary course of business, we and our affiliates
may actively trade the securities of E.piphany for our and such affiliates'
accounts and for the accounts of customers and, accordingly, may at any time
hold long or short positions in such securities.

It is understood that this letter is for the information of the Board of
Directors of E.piphany in connection with its evaluation of the Merger, does not
constitute a recommendation to any stockholder as to how such stockholder should
vote with respect to any matter relating to the Merger, and is not to be quoted
or referred to, in whole or in part, in any registration statement, prospectus
or proxy statement, or in any other document used in connection with the
offering or sale of securities, nor shall this letter be used for any other
purposes, without our prior written consent.

Based upon and subject to the foregoing, it is our opinion that, as of the date
hereof, the Consideration is fair, from a financial point of view, to E.piphany.

Very truly yours,

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

     Article VII of E.piphany's Restated Certificate of Incorporation provides
for the indemnification of directors to the fullest extent permissible under
Delaware law.

     Article VI of E.piphany's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of E.piphany if such
person acted in good faith and in a manner reasonably believed to be in and not
opposed to the best interest of E.piphany, and, with respect to any criminal
action or proceeding, the indemnified party had no reason to believe his or her
conduct was unlawful.

     E.piphany has entered into indemnification agreements with its directors
and executive officers, in addition to indemnification provided for in
E.piphany's Bylaws, and intends to enter into indemnification agreements with
any new directors and executive officers in the future.

     E.piphany has entered into underwriting agreements with the underwriters
for its recent public offerings which provide for indemnification by E.piphany
of the underwriters for some liabilities, including liabilities arising under
the Securities Act of 1933, as amended.

ITEM 22. UNDERTAKINGS

     The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act;

             (ii) 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

        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) The undersigned registrant hereby undertakes that, for purposes of
     determining any liability under the Securities Act, each filing of the
     registrant's annual report pursuant to section 13(a) or section 15(d) of
     the Exchange Act (and, where applicable, each filing of an employee benefit
     plan's annual report pursuant to 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 therein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (5) The undersigned registrant hereby undertakes as follows: 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.

          (6) The registrant undertakes that every prospectus (i) that is filed
     pursuant to paragraph (6) immediately preceding, or (ii) that purports to
     meet the requirements of section 10(a)(3) of the Securities Act and is used
     in connection with an offering of securities subject to Rule 415, will be
     filed as a part of an amendment to the registration statement and will not
     be used until such amendment is effective, and that, for purposes 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.

          (7) The undersigned registrant hereby undertakes to respond to
     requests for information that is incorporated by reference into the
     prospective pursuant to Items 4, 10(b), 11, or 13 of this Form, within one
     business day of receipt of such request, and to send the incorporated
     documents by first class mail or 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.

          (8) 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.

the proceedings taken and are familiar with the proceedings proposed to be taken
