                                 March 10, 2000

Dear fellow stockholder,

     Oberon Software Incorporated has entered into a merger agreement with
OnDisplay, Inc., ObiOne Acquisition Corporation, a Massachusetts corporation and
wholly-owned subsidiary of OnDisplay, and Joseph Chappell as representative of
Oberon's stockholders. Under that agreement, as amended, OnDisplay will acquire
Oberon through the statutory merger of ObiOne Acquisition Corporation, with and
into Oberon. This proxy statement/prospectus is being sent to you to solicit
your proxy to vote for adoption of the merger agreement, as amended, at a
special meeting of stockholders to be held on Thursday, March 30, 2000, at 10:00
a.m. local time at the headquarters of Oberon at 215 First Street, Cambridge,
Massachusetts 02142 and at any adjournment or postponement of that meeting.

     In the merger, each share of Oberon common stock and preferred stock will
be exchanged for .0912 shares of OnDisplay common stock. There is no public
trading market for Oberon common stock or preferred stock. OnDisplay common
stock is quoted on the Nasdaq Stock Market under the symbol "ONDS". The closing
price for OnDisplay common stock reported on the Nasdaq Stock Market on March 6,
2000 was $101.00 per share.

     The merger has been structured with the intent that you will not recognize
gain or loss for federal income tax purposes on the receipt of OnDisplay common
stock in exchange for your Oberon stock. A more detailed discussion of the
material federal income tax consequences of the merger is contained in the
accompanying proxy statement/prospectus.

     Attached is a notice of special meeting of stockholders and a proxy
statement/prospectus relating to the merger. This document describes the merger
in detail. We encourage you to read it carefully and to consider the risk
factors relating to the merger that are described starting on page 22 of this

     A SPECIAL COMMITTEE OF THE BOARD OF DIRECTORS, AS WELL AS THE FULL BOARD OF
DIRECTORS, HAS CAREFULLY CONSIDERED THE TERMS OF THE PROPOSED MERGER, AND

enclosed proxy card and return it promptly in the enclosed prepaid envelope,
whether or not you plan to attend the special meeting of stockholders. Your
prompt cooperation and continued support of Oberon is greatly appreciated.

          QUESTIONS AND ANSWERS FOR ONDISPLAY AND OBERON STOCKHOLDERS

Q: WHY ARE THE COMPANIES PROPOSING TO MERGE? (SEE PAGES 39 AND 40)

A: OnDisplay and Oberon are proposing to merge because we believe the resulting
   combination will strengthen the combined company's product offerings,
   competitive position, management depth, research and development capabilities
   and growth potential.

   We believe that Oberon's business process automation and technology
   integration solutions for business-to-business, business-to-consumer and
   electronic marketplace applications are highly complimentary to existing
   OnDisplay e-business offerings. Creating a combined entity that is stronger
   and more competitive than either company on a standalone basis.

Q: WHAT IS THE OBERON MERGER? (SEE PAGE 38)

A: The board of directors of OnDisplay and Oberon, as well as a special
   committee of the Oberon board of directors, have voted to merge a
   wholly-owned subsidiary of OnDisplay into Oberon, resulting in the exchange
   of Oberon's shares for shares of OnDisplay. This exchange will make Oberon a
   wholly-owned subsidiary of OnDisplay.

Q: WHAT WILL OBERON COMMON AND PREFERRED STOCKHOLDERS RECEIVE IN THE MERGER?

A: When the Oberon merger is completed, Oberon stockholders will receive .0912
   shares of OnDisplay common stock in exchange for each share of Oberon common
   stock or preferred stock they hold. After the merger, the former stockholders
   of Oberon will own approximately 8.8% of OnDisplay. No fractional shares will
   be issued. Instead of any fractional share, Oberon stockholders will receive
   cash, based on such fraction multiplied by $91.575.

   Options or warrants to purchase shares of Oberon common stock will become
   options or warrants to purchase shares of OnDisplay common stock.

Q: WHAT ARE THE TRANSFER RESTRICTIONS ON THE ONDISPLAY COMMON STOCK OBERON
   STOCKHOLDERS WILL RECEIVE IN THE MERGER? (SEE PAGE 55)

A: The OnDisplay common stock to be received by the Oberon stockholders in the
   merger may not be sold or otherwise transferred without the prior written
   consent of OnDisplay until June 14, 2000. However, if OnDisplay stockholders
   whose shares are restricted from transfer by agreements made in connection
   with OnDisplay's initial public offering are permitted to sell their shares
   before June 14, 2000, the former Oberon stockholders will also be permitted
   to sell at that time. In addition, shares of OnDisplay issued in the merger
   to Oberon directors and officers who may be deemed to be affiliates of Oberon
   may be sold during the first year after the merger only under Rule 145
   limitations. Any such persons who become affiliates of OnDisplay will be
   under Rule 144 limitations so long as they have that status.

Q: WILL A PORTION OF THE SHARES ISSUED IN THE MERGER BE PLACED IN ESCROW?

A: Yes. Ten percent of the shares of OnDisplay common stock to be received by
   the stockholders of Oberon will be deposited in escrow to serve as security
   for indemnification of OnDisplay and its affiliates against losses resulting
   from:

   - a breach or inaccuracy of a representation or warranty of Oberon in the
     merger agreement or an instrument delivered in connection with the merger
     agreement;

   - Oberon's failure to perform or comply with a covenant in the merger
     agreement; and

   - Oberon incurring expenses in excess of the amount estimated in the merger
     agreement.

   Escrowed shares that are not needed to satisfy indemnification claims made
   within one year after the merger will be distributed to the former Oberon
   stockholders.

                                        4
<PAGE>   11

Q: DOES THE BOARD OF DIRECTORS OF ONDISPLAY RECOMMEND VOTING IN FAVOR OF THE
   ISSUANCE OF ONDISPLAY SHARES IN THE MERGER?

A: Yes. After careful consideration, OnDisplay's board of directors recommends
   that its stockholders vote in favor of the issuance of shares of OnDisplay
   common stock in the merger.

Q: DOES THE BOARD OF DIRECTORS OF OBERON RECOMMEND VOTING IN FAVOR OF THE OBERON
   MERGER?

A: Yes. Both a special committee of the Oberon board of directors, as well as
   the full board of directors, unanimously recommend that Oberon stockholders
   vote in favor of the Oberon merger agreement, as amended, and the proposed
   merger.

Q: WHAT STOCKHOLDER VOTE IS REQUIRED TO APPROVE THE MERGER?

A: Approval of the merger agreement and the merger under Massachusetts law and
   Oberon's articles of organization requires the affirmative vote of the
   holders of:

   - at least two-thirds of the outstanding shares of common stock and shares of
     series 1 and 2 preferred stock on an as converted basis voting as a single
     class; and

   - at least a majority of the outstanding shares of series 1 and 2 preferred
     stock, each voting as a separate class.

    Holders of at least two-thirds of the outstanding shares of Oberon common
    stock, series 1 and series 2 preferred stock as well as 100% of the
    outstanding series 1 and approximately 64.7% of the outstanding series 2
    preferred stock have agreed, by way of voting agreements, to provide the
    requisite approval.

    Approval of the issuance of OnDisplay common stock in the merger is required
    by a majority of the shares of common stock of OnDisplay present or
    represented by proxy at the special meeting. A majority of the outstanding
    shares of OnDisplay common stock have agreed, by way of voting agreements,
    to approve the issuance.

Q: ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE OBERON
   MERGER?

A: Yes. In evaluating the Oberon merger, you should carefully consider the
   factors discussed in the section entitled "Risk Factors" beginning on page
   22.

A: Mail your signed proxy card in the enclosed return envelope as soon as
   possible so that your shares may be represented at the appropriate meeting.

Q: AS AN OBERON STOCKHOLDER, SHOULD I SEND IN MY OBERON STOCK CERTIFICATES NOW?

   instructions for exchanging your Oberon stock certificates for OnDisplay
   stock certificates.

   Cambridge, Massachusetts 02142.

Q: IF MY ONDISPLAY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER
   VOTE MY SHARES FOR ME?

A: Your broker will vote your shares only if you provide instructions on how to
   vote by following the information provided to you by your broker.

Q: WHAT DO I DO IF I WANT TO CHANGE MY VOTE? (SEE PAGES 33 AND 36)

A: If you want to change your vote, send to the secretary of OnDisplay or the
   clerk of Oberon, as relevant, a later-dated, signed proxy card before your
   meeting or attend the meeting in person. You may also revoke your proxy by

                                        5
<PAGE>   12

   sending written notice to the relevant secretary or clerk before the meeting

A: We hope to complete the merger during the second calendar quarter of 2000.

Q: WILL I RECOGNIZE AN INCOME TAX GAIN OR LOSS ON THE EXCHANGE OF MY OBERON
   SHARES IN THE MERGER?

A: We expect that you will not recognize gain or loss for United States federal
   income tax purposes in connection with the merger, except with respect to
   cash received instead of fractional shares. However, you are urged to consult
   your own tax advisor to determine your particular tax consequences.

Q: AM I ENTITLED TO DISSENTERS' OR APPRAISAL RIGHTS? (SEE PAGE 36)

A: OnDisplay stockholders are not entitled to dissenter's or appraisal rights in
   connection with the merger.

   Each Oberon stockholder is entitled to dissenter's rights. If the merger is
   consummated and if:

   - before the vote on approval of the merger agreement is taken, you file with
     the clerk of Oberon a written objection to the proposed merger stating your
     intention to demand payment for your Oberon shares if the merger is
     consummated;

   - you do not vote in favor of the merger; and

   - you demand in writing from Oberon, within twenty days after notice to you

                          SUMMARY OF THE OBERON MERGER

THE OBERON MERGER (SEE PAGE 38)

     In the Oberon merger, Oberon will merge with a wholly-owned subsidiary of
OnDisplay, called ObiOne Acquisition Corporation. Oberon will survive the merger
as a wholly-owned subsidiary of OnDisplay. Following the merger, Oberon common
and preferred stockholders will be entitled to exchange each of their shares for
 .0912 shares of OnDisplay common stock. The shares of OnDisplay common stock
which Oberon common and preferred stockholders will be entitled to receive may
not be sold or otherwise transferred without the prior written consent of
OnDisplay until June 14, 2000. However, if OnDisplay stockholders whose shares
are restricted from

                                        7
<PAGE>   14

transfer by agreements made in connection with OnDisplay's initial public
offering are permitted to sell those shares prior to June 14, 2000, Oberon
stockholders will be allowed to sell at that time as well.

     The merger agreement, as amended, is attached to this proxy
statement/prospectus as Annex A and Annex AA. You are encouraged to read it
carefully.

ESCROW FUND

     Ten percent of the OnDisplay shares of common stock to be received by the
holders of outstanding Oberon common stock and preferred stock will be deposited
in an escrow fund for a period of one year to serve as security for
indemnification of OnDisplay and its officers, directors and affiliates against
losses resulting from:

     - any breach or inaccuracy of a representation or warranty of Oberon in the
       merger agreement or an instrument delivered in connection to the merger
       agreement;

     - any failure by Oberon to perform or comply with a covenant in the merger
       agreement; or

     - Oberon incurring expenses in excess of the amount estimated in the merger
       agreement.

CONDITIONS TO COMPLETION OF THE OBERON MERGER (SEE PAGE 60)

     OnDisplay's and Oberon's obligations to complete the Oberon merger are
subject to certain closing conditions. These conditions, which must be satisfied
or waived before the completion of the merger, include:

  - No statute, rule, regulation or order is enacted or issued which prohibits
    the merger or makes it illegal.

  - No injunction or other legal restraint prohibiting or preventing the
    consummation of the merger is entered.

  - The merger agreement must be approved by the stockholders of Oberon and the
    issuance of OnDisplay common stock in the merger must be approved by the
    stockholders of OnDisplay.
  - OnDisplay's S-4 registration statement must be declared effective with no
    stop orders or proceedings for suspension pending.

  - OnDisplay and Oberon must each receive from their respective tax counsel, an
    opinion stating that the merger will constitute a reorganization within the
    meaning of Section 368(a) of the Internal Revenue Code.

  - Approvals from any governmental entity required to consummate the merger
    shall have been obtained.

     If either OnDisplay or Oberon waives any conditions, we will each consider
the facts and circumstances at that time and make a determination whether a
resolicitation of proxies from our respective stockholders is appropriate.

VOTE REQUIRED FOR APPROVAL

     The holders of a majority of the shares of OnDisplay common stock present
or represented by proxy at the stockholders' meeting must approve the issuance
of OnDisplay common stock in the merger. OnDisplay stockholders are entitled to
cast one vote per share of OnDisplay common stock owned as of the record date.
As of the record date, OnDisplay stockholders holding approximately 54.2% of
outstanding OnDisplay common stock have agreed to vote their shares of OnDisplay
common stock in favor of the issuance of OnDisplay common stock in the merger.

     The holders of at least two-thirds of the shares of Oberon common stock and
preferred stock outstanding voting together as a single class on an as converted
basis, must approve the merger agreement and the merger. In addition, holders of
at least a majority of each of the series 1 and series 2 preferred stock
outstanding, voting as a separate class, must approve the merger agreement and
the merger. As of March 6, Oberon stockholders who collectively held
approximately 87.6% of the outstanding capital stock and 100% of the series 1
and 64.7% of the series 2 preferred stock outstanding, have agreed to vote their
shares of Oberon capital stock in favor of the merger agreement and the merger.

point of view. The full text of the written opinions of the financial advisors
are attached to the back of this document as Annex B and Annex C, and should be
read carefully in their entireties for a description of the assumptions made,
matters considered and limitations on the review undertaken. The opinion of
Robertson Stephens is directed to the OnDisplay board and the opinion of
SoundView is directed to the special committee of Oberon's board, and these
opinions do not address the prices at which OnDisplay's common stock will trade
after the proposed merger and do not constitute a recommendation as to how to
vote with respect to any matter relating to the proposed merger.

U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (SEE PAGE 53)

     We have structured the Oberon merger so that, in general, OnDisplay,
OnDisplay's stockholders, Oberon and Oberon's stockholders will not recognize
gain or loss for United States federal income tax purposes in the merger, except
for cash payments received by Oberon stockholders instead of fractional shares.
It is a condition to the merger that both OnDisplay and Oberon receive legal
opinions to the effect that the merger will constitute a reorganization within
the meaning of Section 368(a) of the Internal Revenue Code.

ACCOUNTING TREATMENT OF THE OBERON MERGER (SEE PAGE 55)
     OnDisplay intends to account for the merger as a "purchase" for financial
accounting purposes, in accordance with generally accepted accounting
principles.

INTERESTS OF CERTAIN PERSONS IN THE OBERON MERGER (SEE PAGE 49)

     When considering the recommendations of OnDisplay's board of directors and
Oberon's special committee of the board of directors, as well as its full board
of directors, you should be aware that certain OnDisplay and Oberon directors
and executive officers have interests in the merger that are different from, or
are in addition to, yours. These interests include:

  - OnDisplay has agreed to cause the surviving corporation to fulfill and honor
    the obligations pursuant to Oberon's articles of organization and bylaws
    relating to indemnification of directors and officers and any
    indemnification agreements between Oberon and its directors and officers
    existing prior to completion of the merger.

  - M. McMahon and M. Wick have agreed to be employees of OnDisplay after
    completion of the merger and J. Chappell and D. Collard have entered into
    severance agreements effective upon completion of the merger.

  - Oberon has agreed to grant options to certain executive officers prior to
    the completion of the merger that have exercise prices of approximately
    $27.43 per OnDisplay share.

  - J. Mandile is on the board of directors of both OnDisplay and Oberon.
    Entities affiliated with Matrix Partners, a venture capital firm, are
    stockholders of both OnDisplay and Oberon and general partners of Matrix
    Partners serve as directors of both OnDisplay and Oberon.

  - Upon completion of the merger, options to purchase an aggregate of
    approximately 578,000 shares of Oberon common stock granted to directors and
    executive officers of Oberon will accelerate. The foregoing amounts do not
    include options that have

                                       10
<PAGE>   17

    been or may be issued by Oberon after December 31, 1999.

     In considering the fairness of the merger to each of the OnDisplay and
Oberon stockholders, OnDisplay's board of directors and the special committee of
Oberon's board of directors, as well as its full board, took into account these
interests. J. Mandile and T. Barrows, general partners of Matrix Partners and
members of the OnDisplay board of directors were excused from the meetings of
the OnDisplay directors considering and approving the merger. J. Mandile and M.
Humphreys, general partners of Matrix Partners and members of the Oberon board
of directors, were not members of the special committee of the Oberon board of
directors that approved the merger.

DISSENTERS' RIGHTS

     If the merger is completed, Oberon stockholders who object to the merger
are entitled to appraisal rights under Massachusetts law. In order to exercise
appraisal rights, Oberon stockholders must strictly adhere to the provisions of
Massachusetts law governing appraisal rights. A copy of the relevant provisions
of Massachusetts law are attached hereto as Annex D.

     In order to exercise your appraisal rights, you must take the following
steps:

     - send a written objection to the merger to Oberon before the special
       meeting stating your intention to demand payment for your shares of
       Oberon capital stock if the merger occurs;

     - do NOT vote in favor of the merger; and

     - send a written demand to Oberon for payment for your Oberon shares within
       twenty days after you received notice from Oberon that the merger has
       occurred. Oberon will send the notice within 10 days after the merger is
       completed.

     The written objection and written demand should be delivered registered or
certified mail, return receipt requested to Oberon Software Incorporated, 215
First Street, Cambridge, Massachusetts 02142, Attention: Clerk.

RESTRICTIONS ON THE ABILITY TO SELL ONDISPLAY STOCK (SEE PAGE 55)

     All shares of OnDisplay common stock received by Oberon stockholders in
connection with the Oberon merger will be freely transferable unless the holder
is considered an affiliate of either Oberon or OnDisplay under the Securities
Act. Shares of OnDisplay held by affiliates may only be sold pursuant to a
registration statement or an exemption from the Securities Act.

     The shares of OnDisplay common stock that Oberon stockholders will be
entitled to receive, may not be sold or otherwise transferred without the prior
written consent of OnDisplay until June 14, 2000. However, if OnDisplay
stockholders whose shares are restricted from transfer by agreements made in
connection with OnDisplay's initial public offering not to sell their shares of
OnDisplay common stock are permitted to sell their shares before June 14, 2000,
Oberon stockholders will also be permitted to sell at that time. In addition,
shares of OnDisplay common stock deposited on behalf of Oberon stockholders into
the escrow fund may not be transferred during the one year term of the escrow
fund unless the shares are sold by the stockholder representative on the owner's
behalf and at least $91.5750 per share from the sale is placed in the fund in
lieu of the shares sold.

FORWARD-LOOKING STATEMENTS IN THIS PROSPECTUS/ PROXY STATEMENT

     This proxy statement/prospectus contains forward-looking statements within
the safe harbor provisions of the Private Securities Litigation Reform Act.
These statements include statements with respect to OnDisplay's and Oberon's
financial condition, results of operations and business and on the expected
impact of the Oberon merger on OnDisplay's financial performance. Words such as
anticipates, expects, intends, plans, believes, seeks, estimates and similar
expressions identify forward-looking statements.

     These forward-looking statements are not guarantees of future performance
and are subject to certain risks and uncertainties that could cause actual
results to differ materially from the results contemplated by the
forward-looking statements.

                                       11
<PAGE>   18

These risks and uncertainties include the following:

     General risks relating to the proposed merger

     - OnDisplay and Oberon may not achieve the benefits they expect from the
       merger which may have a material adverse effect on the combined company's
       business, financial condition and operating results and/or could result
       in loss of key personnel.

     - Oberon stockholders will receive a fixed number of shares of OnDisplay
       common stock despite changes in market value of OnDisplay common stock.

     Risks relating to OnDisplay and the combined company

     - We have a history of losses and expect losses in the future. If we do not
       achieve or sustain profitability in the future, our viability will be in
       doubt and our stock price will decline.

     - We may need to raise additional capital that may not be available on
       terms favorable to us, if at all.

     - Our quarterly operating results are volatile and difficult to predict and
       if we fail to meet the expectations of public market analysts and
       investors, the market price of our common stock may decrease
       significantly.

     - Our revenues depend on a limited number of product lines.

     - The market for e-business portals and e-marketplaces is new and emerging
       and if it does not grow as rapidly as we anticipate or fails to emerge at
       all, our planned growth and financial objectives will not be met.

     - Our products have long and variable sales cycles; it is therefore
       difficult to predict the timing of individual orders and match revenues
       with operating expenses, which are relatively fixed in the short term.

     - We face competition primarily from companies developing their own
       internal e-business infrastructure systems and other providers of
       e-business infrastructure solutions, and if we are unable to compete
       successfully, we will not achieve our financial objectives.

     - We need to expand our direct sales operations if we are to increase
       market awareness of and revenues derived from our products and related
       services.

     - Our operations and growth prospects may be significantly impeded if we
       are unable to retain our key personnel or attract additional key
       personnel, especially because experienced and skilled personnel are in
       short supply.

     - If we fail to successfully manage our planned expansion of operations,
       our growth prospects will be diminished and our operating expenses could
       exceed budgeted amounts.

     - If we fail to adequately respond to rapid technological changes, our
       existing products will become obsolete or unmarketable.

     - If our products contain errors, our revenues and net operating results
       will be negatively impacted and our reputation and the market acceptance
       of these products will be jeopardized.

     - If we fail to adequately protect our intellectual property rights our
       ability to compete could be seriously harmed, and if other companies
       bring lawsuits claiming that we infringe their intellectual property
       rights we could be liable for significant damages.

     - There is substantial risk that future regulations could be enacted that
       either directly restrict our business or indirectly impact our business
       by limiting the growth of Internet commerce.

     - Our planned international operations may not be successful and will make
       us susceptible to various risks.

     - Our systems are susceptible to external events that may impact our
       ability to conduct our business operations.

                                       12
<PAGE>   19

     - Problems related to the "year 2000 issue" could adversely affect our
       business.

     - We may need to raise additional capital that may not be available on
       terms favorable to us, if at all.

     - This document contains forward-looking statements; these statements are
       not guarantees of future performance and are susceptible to risks,
       uncertainties and other factors, some of which are beyond our control.

     In evaluating the Oberon merger, you should carefully consider the
discussion of these and other factors in the section entitled "Risk Factors" on
page 22.

                     NOTES TO UNAUDITED PRO FORMA COMBINED
                              FINANCIAL STATEMENTS

NOTE 1 -- PRO FORMA BASIS OF PRESENTATION:

     The unaudited pro forma combined balance sheet as of December 31, 1999
reflects the combination of the financial statements of OnDisplay and Oberon as
of December 31, 1999 and the unaudited pro forma combined statement of
operations reflects the combined results of operations of OnDisplay and Oberon
or if the merger had taken place on January 1, 1999.

     These unaudited pro forma combined financial statements reflect the
issuance of 1,922,371 shares of OnDisplay common stock in exchange for an

     The actual number of shares of OnDisplay common stock to be issued will be
determined at the Effective Time based on the number of shares of Oberon common
stock outstanding at that date. In addition, based on the number of Oberon
options estimated to be outstanding at the Effective Time, OnDisplay would
assume options to purchase 343,180 shares of OnDisplay common stock. The actual
number of options to be assumed will depend on the actual number of Oberon
options outstanding at the Effective Time.

NOTE 2 -- PRO FORMA ADJUSTMENTS:

     The unaudited pro forma combined financial statements give effect to the
allocation of the total purchase price to the assets and liabilities of Oberon
based on their respective fair values and the related amortization over the
estimated useful lives of amounts allocated to intangible assets, including
goodwill. The unaudited pro forma combined balance sheet also reflect the write
off of in-process research and development at December 31, 1999. The unaudited
pro forma combined statement of operations reflects the write off of in-process
research & development as of December 31, 1999. The unaudited pro forma net loss
per share is based on the weighted average number of shares of OnDisplay common
stock outstanding during the year plus the shares issued in the merger, assumed
to have been issued on January 1, 1999.

     Oberon stockholders are advised to obtain current market quotations for
OnDisplay common stock. No assurance can be given as to the market prices of
OnDisplay common stock at any time before the consummation of merger or at any
time after merger. Because the exchange ratio is fixed, the exchange ratio will
not be adjusted to compensate Oberon stockholders for any decrease in the market
price of OnDisplay common stock which could occur before the merger becomes
effective. In the event the market price of OnDisplay common stock decreases or
increases prior to the consummation of the merger, the value of the OnDisplay
common stock to be received in the merger in exchange for Oberon capital stock
would correspondingly decrease or increase.

     OnDisplay and Oberon have never paid cash dividends on their respective
shares of capital stock. The OnDisplay board presently intends to retain any
earnings for use in its business and has no present intention to pay cash
dividends before or after the merger.

                                  RISK FACTORS

     The merger involves a high degree of risk. By voting in favor of the Oberon
merger, you will be choosing to invest in OnDisplay common stock. An investment
in OnDisplay common stock involves a high degree of risk. In addition to the
other information contained in this proxy statement/prospectus, you should
carefully consider the following risk factors in deciding whether to vote for
the merger.

GENERAL RISKS RELATING TO THE PROPOSED MERGER

ONDISPLAY AND OBERON MAY NOT ACHIEVE THE BENEFITS THEY EXPECT FROM THE MERGER
WHICH MAY HAVE A MATERIAL ADVERSE EFFECT ON THE COMBINED COMPANY'S BUSINESS,
FINANCIAL CONDITION AND OPERATING RESULTS AND/OR COULD RESULT IN LOSS OF KEY
PERSONNEL.

     OnDisplay will need to overcome significant issues in order to realize any
benefits or synergies from the merger, including the timely, efficient and
successful execution of a number of post-merger events. Key events include:

     - integrating the operations of the two companies;

     - retaining and assimilating the key personnel of each company;

     - offering the existing products and services of each company to the other
       company's customers;

     - retaining the existing customers and strategic partners of each company;

     - developing new services that utilize the assets of both companies; and

     - maintaining uniform standards, controls, procedures and policies.

     The successful execution of these post-merger events will involve
considerable risk and may not be successful. These risks include:

     - the potential disruption of the combined company's ongoing business and
       distraction of its management;

     - the difficulty of incorporating acquired technology and rights into the
       combined company's products and services;

     - unanticipated expenses related to technology integration;

     - the impairment of relationships with employees and customers as a result
       of any integration of new management personnel; and

     - potential unknown liabilities associated with the acquired business.

     The combined company may not succeed in addressing these risks or any other
problems encountered in connection with the merger. If the benefits of the
merger do not exceed the costs associated with the merger, including any
dilution to OnDisplay's stockholders resulting from the issuance of shares in
connection with the merger, OnDisplay's financial results, including earnings
per share, could be adversely affected.

OBERON STOCKHOLDERS WILL RECEIVE A FIXED NUMBER OF SHARES OF ONDISPLAY COMMON
STOCK DESPITE CHANGES IN MARKET VALUE OF ONDISPLAY COMMON STOCK.

     Upon the merger's completion, each share of Oberon common and preferred
stock, will be exchanged for .0912 shares of OnDisplay common stock. There will
be no adjustment for changes in the market price of OnDisplay common stock. In
addition, neither Oberon nor OnDisplay may terminate the merger agreement or
"walk away" from the merger solely because of changes in the market price of
OnDisplay common stock. Accordingly, the specific dollar value of OnDisplay
common stock that Oberon stockholders will receive upon the merger's completion
will depend on the market value of OnDisplay common stock when the merger is
completed and may decrease from the date you submit your proxy. The

                                       22
<PAGE>   29

share price of OnDisplay common stock has risen substantially over a short
period which could increase its susceptibility to a sharp decline in the event
of any adverse development affecting OnDisplay or technology company stock
prices. We urge you to obtain recent market quotations for OnDisplay common
stock. OnDisplay cannot predict or give any assurances as to the market price of
OnDisplay common stock at any time before or after the completion of the merger.

THE MARKET PRICE OF ONDISPLAY COMMON STOCK MAY DECLINE AS A RESULT OF THE
MERGER.

     The market price of OnDisplay common stock may decline as a result of the
merger for a number of reasons including if:

     - the integration of OnDisplay and Oberon is unsuccessful;

     - OnDisplay does not achieve the perceived benefits of the merger as
       rapidly or to the extent anticipated by financial or industry analysts;

     - the effect of the merger on OnDisplay's financial results is not
       consistent with the expectations of financial or industry analysts; or

     - investors react negatively to the effect on OnDisplay's net operating
       results from the annual amortization over four years of the approximately
       $184,620,000 of goodwill created by the merger.

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

     The directors and officers of Oberon participate in arrangements that
provide them with interests in the merger that are different from, or in
addition to, yours, including the following:

     - Options to purchase shares of Oberon common stock granted to directors
       and executive officers of Oberon will accelerate upon the completion of
       the merger. These options cover an aggregate of approximately 578,000
       shares, excluding any options that may be granted by Oberon after
       December 31, 1999.

     - M. McMahon and M. Wick have agreed to be employees of OnDisplay after
       completion of the merger and J. Chappell and D. Collard have entered into
       severance agreements in the form attached to the merger agreement.

     - J. Mandile is on the board of directors of both OnDisplay and Oberon and
       owns OnDisplay common stock. Entities affiliated with Matrix Partners, a
       venture capital firm, are stockholders of both OnDisplay and Oberon. One
       general partner of Matrix Partners serves as a director of OnDisplay and
       another serves as a director of Oberon.

     - OnDisplay has agreed to cause the surviving corporation in the merger to
       fulfill and honor in all respects the obligations of Oberon pursuant to
       its articles of organization and bylaws and any indemnification
       agreements between Oberon and each of its directors and officers existing
       prior to the completion of the merger.

     For the above reasons, the directors and officers of Oberon could be more
likely to vote to favor the merger than if they did not hold these interests.
Oberon stockholders should consider whether these interests may have influenced
these directors and officers to support or recommend the merger.

FAILURE TO COMPLETE THE MERGER COULD NEGATIVELY IMPACT ONDISPLAY'S STOCK PRICE
AND OBERON AND/OR ONDISPLAY'S FUTURE BUSINESS AND OPERATIONS.

     If the merger is not completed for any reason, Oberon and OnDisplay may be
subject to a number of material risks, including the following:

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

                                       23
<PAGE>   30

     - costs related to the merger, such as legal, accounting and financial
       advisor fees, must be paid even if the merger is not completed.

     In addition, Oberon's and/or OnDisplay's customers and strategic partners,
in response to the announcement of the merger, may delay or defer decisions
concerning either company. Any delay or deferral of those decisions by
customers, strategic partners or suppliers could have a material adverse effect
on the business of the affected company, regardless of whether the merger is
ultimately completed. Similarly, current and prospective Oberon and/or OnDisplay
employees may experience uncertainty about their future roles with the combined
companies until OnDisplay's strategies with regard to Oberon are announced or
executed. This may adversely affect Oberon's and/or OnDisplay's ability to
attract and retain key management, sales, marketing and technical personnel.

     Further, if the merger is terminated and Oberon's board of directors
determines to seek another merger or business combination, there can be no
assurance that it will be able to find a partner willing to pay an equivalent or
more attractive price than the price to be paid in the merger. In addition,
while the merger agreement is in effect, Oberon is prohibited from soliciting,
initiating or encouraging or entering into certain extraordinary transactions,
such as a merger, sale of assets or other business combination, with any party
other than OnDisplay.

RISKS RELATING TO ONDISPLAY AND THE COMBINED COMPANY

WE HAVE A HISTORY OF LOSSES AND EXPECT LOSSES IN THE FUTURE. IF WE DO NOT
ACHIEVE OR SUSTAIN PROFITABILITY IN THE FUTURE, OUR VIABILITY WILL BE IN DOUBT
AND OUR STOCK PRICE WILL DECLINE.

     We were incorporated in August 1996 and first recognized revenues in the
fourth quarter of 1997. As of December 31, 1999, we had an accumulated deficit
of approximately $31.2 million. To date, we have not had a profitable quarter
and do not expect to have a profitable quarter in 2000. If we do achieve
profitability, we cannot be certain that we can sustain profitability in the
future. To date, we have funded our operations from the sale of equity
securities and have not generated cash from operations. We expect to continue to
incur significant costs developing and introducing enhancements to our suite of
e-business infrastructure applications and related services and expanding our
direct sales and marketing activities, leading to losses at least through 2002.
Included in our expenses will be stock-based compensation as a result of stock
options granted through December 15, 1999, of $15.4 million in 2000, $8.0
million in 2001, $4.2 million in 2002 and $1.6 million in 2003. These losses
could impede our ability to compete effectively by creating doubt among our
potential customers as to our long-term viability, and cause a decrease in the
market price of our common stock. Although our revenues have grown in recent
quarters, we do not believe that we can sustain these growth rates, or that
these growth rates are indicative of future revenue growth rates. See "Selected
Financial Data" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

WE MAY NEED TO RAISE ADDITIONAL CAPITAL THAT MAY NOT BE AVAILABLE ON TERMS
FAVORABLE TO US, IF AT ALL.

     We may need to raise additional capital and we cannot be certain that we
will be able to obtain additional financing on favorable terms, if at all. If we
cannot raise additional capital on acceptable terms, we may not be able to
develop or enhance our products and services, take advantage of future
opportunities or respond to competitive pressures or unanticipated requirements.

OUR QUARTERLY OPERATING RESULTS ARE VOLATILE AND DIFFICULT TO PREDICT AND IF WE
FAIL TO MEET THE EXPECTATIONS OF PUBLIC MARKET ANALYSTS AND INVESTORS, THE
MARKET PRICE OF OUR COMMON STOCK MAY DECREASE SIGNIFICANTLY.

     Our quarterly operating results have varied in the past and may vary
significantly in the future. Because our business is evolving rapidly and we
have a limited operating history, we have little experience in forecasting our
revenues. Since our operating results are volatile and difficult to predict, we
believe that period-to-period comparisons of our operating results are not a
reliable indication of our future performance. Our future quarterly operating
results may be below the expectations of public market

                                       24
<PAGE>   31

analysts and investors. In this event, the market price of our common stock may
decrease significantly. Our future quarterly operating results may vary for
several reasons, including the numerous risk factors discussed below.

     In the past, we have recognized a substantial portion of our revenues in
the last few days of a quarter, which is typical of many companies in the
software industry, and we believe is primarily due to the budgetary cycles of
and the timing of purchasing decisions by our customers. Accordingly, we cannot
accurately predict our financial results for any quarter until very late in that
quarter. In addition, we derive a significant portion of our revenues in each
quarter from a small number of large orders. A delay in completing an
anticipated sale near the end of a quarter can seriously harm our net operating
results for that quarter.

     Our expense levels are relatively fixed in the short term and are based, in
part, on our expected future revenues. Our inability to adjust spending in a
timely manner to compensate for any unexpected revenue shortfall could
accentuate the negative effect on our quarterly results.

OUR REVENUES DEPEND ON A LIMITED NUMBER OF PRODUCT LINES.

     Most of our revenues in 1998 and 1999, were derived from software licenses
and service fees from one suite of products, CenterStage, which until recently
has consisted of CenterStage eContent and CenterStage eIntegrate. We have
recently introduced three new products to our CenterStage product suite,
CenterStage eNotify, CenterStage eBizXchange and CenterStage eSyndicate.
Additionally, upon completion of this offering, we will offer an
Oberon-developed product, eEnterprise. We expect that the CenterStage suite of
products will continue to account for the substantial majority of our total
revenues for at least the next several quarters.

     Our products are at an early stage of commercialization, particularly our
three new products. Therefore, the level of market acceptance they will attain
is difficult to forecast. Market acceptance could be seriously impeded in the
following circumstances:

     - broad standards for conducting e-business emerge and become widely
       adopted, thus reducing the need for our infrastructure products;

     - information services departments of potential customers choose instead to
       create their e-business portals and e-marketplaces internally or use
       third-party professional developers to create and maintain their sites;

     - competitors develop products, technologies or capabilities that render
       our CenterStage products and related services obsolete or noncompetitive
       or that shorten the life cycles of these products and services;

     - our CenterStage products do not meet customer performance needs or fail
       to remain free of significant software defects or bugs; or

     - we are unable to recruit and retain the additional sales personnel needed
       to effectively market our CenterStage products.

     Furthermore, to remain competitive, software products like ours typically
require frequent updates that add new features. There can be no assurance that
we will succeed in creating and selling updated or new versions of our
CenterStage products. A decline in demand for, or in the average selling price
of, our CenterStage products would have a direct negative effect on our primary
source of revenues and could cause our stock price to fall.

IT DOES NOT GROW AS RAPIDLY AS WE ANTICIPATE OR FAILS TO EMERGE AT ALL, OUR
PLANNED GROWTH AND FINANCIAL OBJECTIVES WILL NOT BE MET.

     Our success is dependent on the emergence of the market for e-business
portals and e-marketplaces. We are planning to dedicate all of our sales,
marketing and product development efforts toward e-business portals and
e-marketplaces. If these markets do not develop as rapidly as we expect, our
planned growth and financial objectives will not be met. A number of factors
could prevent or hinder the emergence of these markets, including the following:

     - the unwillingness of customers to change their traditional method of
       conducting commerce;

     - the failure of the Internet network infrastructure to keep pace with
       substantial growth; and

     - adverse publicity and consumer concern about the security of electronic
       commerce transactions.

OUR CENTERSTAGE PRODUCTS HAVE LONG AND VARIABLE SALES CYCLES; IT IS THEREFORE
DIFFICULT TO PREDICT THE TIMING OF INDIVIDUAL ORDERS AND MATCH REVENUES WITH
OPERATING EXPENSES, WHICH ARE RELATIVELY FIXED IN THE SHORT TERM.

     Variations in the length of our sales cycles could cause our revenues to
fluctuate widely from period to period. Because our operating expenses are
relatively fixed over the short term, these revenue fluctuations could have an
accentuated effect on our net operating results in some future periods. While
the average sales cycle for our CenterStage products has been approximately 75
days, our sales cycles could be much longer for larger opportunities with new
customers. Since a number of factors influence the sales process, the period
between our initial contact with a new customer and the time we recognize
revenues from that customer varies widely. We spend significant time educating
and providing information to our prospective customers regarding the use and
benefits of our CenterStage products. Even after purchase, our customers tend to
deploy our solution slowly and deliberately. Deployment schedules depend on the
specific technical capabilities of each customer, the size of the deployment,
the complexity of each customer's network environment, and the quantity of
hardware and the degree of hardware configuration required.

WE FACE COMPETITION PRIMARILY FROM COMPANIES DEVELOPING THEIR OWN INTERNAL
E-BUSINESS INFRASTRUCTURE SYSTEMS AND OTHER PROVIDERS OF E-BUSINESS
INFRASTRUCTURE SOLUTIONS, AND IF WE ARE UNABLE TO COMPETE SUCCESSFULLY, WE WILL
NOT ACHIEVE OUR FINANCIAL OBJECTIVES.

     The market for e-business infrastructure applications and services is
intensely competitive, rapidly evolving and susceptible to significant
technological change. We expect the intensity of our competition to increase in
the future. Many of our competitors have longer operating histories,
significantly greater financial, technical, marketing and other resources,
significantly greater name recognition and a larger installed base of customers
than we have. In addition, many of our competitors have well-established
relationships with current and potential customers of ours, have extensive
knowledge of our industry and are capable of offering alternative solutions. As
a result, our competitors may be able to respond more quickly to new or emerging
technologies and changes in customer requirements, or to devote greater
resources to the development, promotion and sale of their products and services
than we can. In addition, many of our current and potential competitors have
established or may establish cooperative relationships among themselves or with
third parties that may improve their ability to address customer needs.
Accordingly, it is possible that new competitors or alliances among competitors
may emerge and rapidly acquire significant market share. Increased competition
is likely to result in price reductions, reduced gross margins and loss of
market share, any of which could negatively impact our ability to sell our
products at the price levels required to support our continuing operations. See
"Business -- Competition" for a discussion of our current and potential
competitors.

WE NEED TO EXPAND OUR DIRECT SALES OPERATIONS IF WE ARE TO INCREASE MARKET
AWARENESS OF AND REVENUES DERIVED FROM OUR CENTERSTAGE PRODUCTS AND RELATED
SERVICES.

     If we fail to expand our direct sales capabilities as we have planned, our
prospects for revenue growth will be diminished. Our CenterStage products and
related services require a sophisticated sales effort targeted at senior
management of our prospective customers. We have recently expanded our direct
sales force and plan to hire additional sales personnel. Competition for
qualified sales personnel is intense in each of the locations we plan to expand,
and we might not be able to hire and retain the type and number of sales
personnel we are targeting. New hires will require extensive training and
typically take several months to achieve productivity. We cannot be certain that
our recent hires will be as productive as necessary.

OUR OPERATIONS AND GROWTH PROSPECTS MAY BE SIGNIFICANTLY IMPEDED IF WE ARE
UNABLE TO RETAIN OUR KEY PERSONNEL OR ATTRACT ADDITIONAL KEY PERSONNEL,
ESPECIALLY BECAUSE EXPERIENCED AND SKILLED PERSONNEL ARE IN SHORT SUPPLY.

     Competition for key personnel is intense, particularly in the San Francisco
Bay Area, where our headquarters are located. We have experienced difficulties
attracting, hiring, training and retaining new personnel in the past, and our
key personnel, including members of our management team, may terminate their
employment with us or decide to work for one of our competitors at any time for
any reason. Currently, we are particularly dependent upon the services of our
founder and Chief Executive Officer, M. Pine, and founder and Chief Technical
Officer, T. Dung. The loss of M. Pine's or T. Dung's services would materially
impede the operation and growth of our business. We do not maintain key person
life insurance for any of our personnel.

IF WE FAIL TO SUCCESSFULLY MANAGE OUR PLANNED EXPANSION OF OPERATIONS, OUR
GROWTH PROSPECTS WILL BE DIMINISHED AND OUR OPERATING EXPENSES COULD EXCEED
BUDGETED AMOUNTS.

     Our ability to offer our CenterStage products and related services in a
quickly evolving market requires an effective planning and management process.
We have expanded our operations rapidly since inception, and we intend to
continue to expand them in the foreseeable future. This rapid growth places
significant demand on our managerial and operational resources and our internal
training capabilities. In addition, we have recently hired a significant number
of employees and plan to further increase our total headcount. We also plan to
expand the geographic scope of our operations, both domestically and
internationally. This expansion will continue to substantially burden our
management team. To manage growth effectively, we must:

     - implement and improve our operational, financial and other systems,
       procedures and controls on a timely basis;

     - expand, train and manage our workforce, particularly our sales and
       marketing and support organizations; and

     - identify and move into suitable office space to expand our facilities.

     We cannot be certain that our systems, procedures or controls will be
adequate to support our current or future operations or that our management will
be able to manage expansion and still achieve the rapid execution necessary to
meet our growth expectations. Failure to manage our growth effectively could
diminish our growth prospects and could result in lost opportunities as well as
operating expenses exceeding the amount budgeted.

IF WE FAIL TO ADEQUATELY RESPOND TO RAPID TECHNOLOGICAL CHANGES, OUR EXISTING
PRODUCTS WILL BECOME OBSOLETE OR UNMARKETABLE.

     New approaches to gather, exchange, integrate, personalize and syndicate
information over the Internet based on new technologies and industry standards
could render our CenterStage products obsolete and unmarketable. We believe that
to succeed we must enhance our CenterStage products, develop new
                                       27
<PAGE>   34

products on a timely basis to keep pace with technological developments and
satisfy the increasingly sophisticated requirements of our customers. Therefore,
we cannot be certain that we will successfully respond to technological change,
evolving industry standards or customer requirements. If we are unable to
adequately respond to these changes, our revenues and market share could rapidly
decline. In connection with the introduction of new products and enhancements,
we have experienced development delays and related cost overruns, which are not
unusual in the software industry. We could encounter these problems or more
serious delays in the future. Any delays in developing and releasing new
products or enhancements to our CenterStage products could result in:

     - customer dissatisfaction;

     - cancellation of orders and license agreements;

     - negative publicity;

     - loss of revenues;

     - slower market acceptance; and

     - legal action by customers against us.

     Our CenterStage products are designed to work on a variety of hardware and
software platforms used by our customers. However, these products may not
operate well with future versions of hardware and software platforms,
programming languages, database environments, accounting and other systems that
our customers use. We must constantly modify and improve our technology to keep
pace with changes made to these platforms and to operational applications and
other Internet-related applications. This may result in uncertainty relating to
the timing and nature of new product announcements, introductions or
modifications, which may harm our business. If we fail to modify or improve our
CenterStage products in response to evolving industry standards, they could
rapidly become obsolete or unmarketable, which would have a direct negative
effect on our revenues.

IF OUR CENTERSTAGE PRODUCTS CONTAIN ERRORS, OUR REVENUES AND NET OPERATING
RESULTS WILL BE NEGATIVELY IMPACTED AND OUR REPUTATION AND THE MARKET ACCEPTANCE
OF THESE PRODUCTS WILL BE JEOPARDIZED.

     Our e-business infrastructure applications are complex and may contain
undetected errors or result in system failures, especially when first introduced
or when new versions or enhancements are released. Despite extensive testing,
errors could occur in any of our current or future product offerings after
commencement of commercial shipments. We have discovered software defects in our
new products after their introduction. Testing of our CenterStage products is
particularly challenging because it is difficult to simulate the wide variety of
computer environments into which they are deployed. The implementation of our
CenterStage products typically involves working with sophisticated software,
computing and communications systems. If our software contains undetected errors
or we fail to meet our customers' expectations in a timely manner we could
experience:

     - loss of or delay in revenues and loss of market share;

     - loss of customers;

     - failure to achieve market acceptance;

     - diversion of development resources;

     - diversion of customer support resources;

     - negative publicity;

     - increased service and warranty costs;

     - legal actions by customers against us; and

     - increased insurance costs.

                                       28
<PAGE>   35

     Because our customers use our CenterStage products for mission-critical
applications, errors or defects in or other performance problems associated with
these products could result in financial or other damages to our customers. Our
customers may then seek damages from us for their losses. We have not
experienced any product liability claims to date. However, a product liability
claim brought against us, even if not successful, would likely be time-consuming
and costly and could harm our reputation.

     Our licenses with customers generally contain provisions designed to limit
our exposure to potential product liability claims such as disclaimers of
warranties and limitations on liability for special, consequential and
incidental damages. In addition, our license agreements generally limit the
amounts recoverable for damages to the amounts paid by our customers to us for
the products or services giving rise to the damages. We cannot be certain that
the limitations of liability we include in our contracts will be enforceable
since existing or future laws or unfavorable judicial decisions could negate
these liability limiting provisions. The successful assertion of one or more
large claims that exceed contractual limitations on our liability could have a
significant negative impact on our results of operations and cause our stock
price to fall.

IF WE FAIL TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS OUR ABILITY TO
COMPETE COULD BE SERIOUSLY HARMED, AND IF OTHER COMPANIES BRING LAWSUITS
CLAIMING THAT WE INFRINGE THEIR INTELLECTUAL PROPERTY RIGHTS WE COULD BE LIABLE
FOR SIGNIFICANT DAMAGES.

     Our success depends in large part on our ability to adequately protect our
intellectual property rights. We seek to protect our source code, documentation
and other written materials under trade secret and copyright laws, which afford
only limited protection. We require our customers to enter into license
agreements, which impose restrictions on our customers' ability to utilize our
CenterStage products. In addition, we seek to avoid disclosure of our trade
secrets by, among other methods, restricting access to our source code and
requiring those persons with access to our proprietary information to sign
confidentiality agreements with us. However, some of these confidentiality
agreements contain provisions that may permit these persons, in some
circumstances, to develop products based on our proprietary information as a
result of their access to our source code. If these persons develop products
based on our proprietary information, the value of our proprietary information
will be adversely impacted. Despite our efforts to protect our proprietary
rights, unauthorized parties may attempt to copy aspects of our technology or to
obtain and use information that we regard as proprietary. Policing unauthorized
use of our technology is difficult, and while we are unable to determine the
extent to which piracy of our CenterStage products exists, software piracy can
be a persistent problem. In addition, as we expand our operations globally, we
become increasingly exposed to intellectual property infringement since the laws
of some foreign countries do not protect our proprietary rights to as great an
extent as the laws of the United States. Our means of protecting our proprietary
rights may not be adequate and our competitors may copy our CenterStage
products, independently develop similar technology, or design around our
intellectual property. If we fail to adequately protect our intellectual
property, our ability to compete may be seriously harmed.

     There has been a substantial amount of litigation in the software industry
regarding intellectual property rights. It is possible that in the future third
parties may claim that our current or future products infringe their
intellectual property. We expect that software developers will increasingly be
susceptible to infringement claims as the number of products and competitors in
our industry segment grows and the functionality of products in different
industry segments overlaps. Any intellectual property claims, with or without
merit, could be time-consuming, result in costly litigation, cause product
shipment delays or require us to enter into royalty or licensing agreements. Any
royalty or licensing agreements, if required, may not be available on terms
acceptable to us, or may not be available at all, which could jeopardize the
viability of our business.

                                       29
<PAGE>   36

THERE IS SUBSTANTIAL RISK THAT FUTURE REGULATIONS COULD BE ENACTED THAT EITHER
DIRECTLY RESTRICT OUR BUSINESS OR INDIRECTLY IMPACT OUR BUSINESS BY LIMITING THE
GROWTH OF INTERNET COMMERCE.

     As Internet commerce evolves, we expect federal, state or foreign agencies
to adopt regulations covering many issues, including user privacy, pricing,
content and quality of products and services. If enacted, these laws, rules or
regulations could limit the market for our CenterStage products and related
services, which could adversely affect our operating results and business
prospects. Although many of these regulations may not apply to our business
directly, we expect that laws regulating the solicitation, collection or
processing of personal/consumer information could indirectly affect our
business. The Telecommunications Act of 1996 prohibits some types of information
and content from being transmitted over the Internet. The prohibition's scope
and the liability associated with a Telecommunications Act violation are
currently unsettled. In addition, although substantial portions of the
Communications Decency Act were held to be unconstitutional, we are unsure
whether similar legislation will be enacted and upheld in the future. It is
possible that legislation could expose companies involved in Internet commerce
to liability, which could limit the growth of Internet commerce generally.
Legislation like the Telecommunications Act and the Communications Decency Act
could dampen the growth of Internet usage and decrease its acceptance as a
commercial medium. Moreover, the applicability to the Internet of existing laws
in various jurisdictions governing issues such as property ownership, sales tax,
libel and personal privacy is uncertain and may take years to resolve. Our costs
could increase and our growth could be harmed by any new legislation or
regulation, the application of laws and regulations from jurisdictions whose
laws do not currently apply to our business, or the application of existing laws
and regulations to the Internet and on-line businesses.

OUR PLANNED INTERNATIONAL OPERATIONS MAY NOT BE SUCCESSFUL AND WILL MAKE US
SUSCEPTIBLE TO VARIOUS RISKS.

     We began our international operations in the fourth quarter of 1999 by
hiring our initial employees in Europe. Establishing our international
operations will require significant management attention and financial resources
and could harm our financial performance by increasing our costs. We have very
limited experience in marketing, selling and distributing our CenterStage
products and related services internationally. We may encounter difficulties in
staffing and managing offices in foreign countries because of our inexperience
and unfamiliarity with local conditions, as well as shortages of qualified
personnel in some countries. Some countries provide little or no protection of
intellectual property rights. Our products may be copied with impunity in such
countries. We may find that the costs of customizing our products in some
foreign countries exceeds our estimates or results in delays in product
readiness. Some countries provide only minimal levels of protection to trade
creditors in collecting amounts due, which could result in difficulties in
collecting accounts receivable.

OUR SYSTEMS ARE SUSCEPTIBLE TO EXTERNAL EVENTS THAT MAY IMPACT OUR ABILITY TO
CONDUCT OUR BUSINESS OPERATIONS.

     We are vulnerable to a major earthquake and other calamities. Our
operational facilities are located in the San Francisco Bay area, a seismically
active region. Our computer systems, as well as the telecommunications and other
infrastructure serving our operations, are potentially vulnerable to a major
earthquake. We have not undertaken a systematic analysis of the potential
consequences to our business and financial results from a major earthquake and
do not have a recovery plan for earthquake, fire, flood, systemic power or
communication failure, sabotage or similar disasters. We are unable to predict
the effects of any such event, but the effects could be seriously harmful to our
business.

PROBLEMS RELATED TO THE "YEAR 2000 ISSUE" COULD ADVERSELY AFFECT OUR BUSINESS.

     The "year 2000 issue" refers generally to the problems that some software
may have in determining the correct century for the year. For example, software
with date-sensitive functions that is not year 2000 compliant may not be able to
distinguish whether "00" means 1900 or 2000, which may result in failures or the
creation of erroneous results. We designed our CenterStage products to be year
2000 compliant provided that the operating system of the host computer and any
other software used with our products are
                                       30
<PAGE>   37

year 2000 compliant. Risks are posed if, despite our investigation and
remediation efforts, one or more of the following occurs:

     - our own CenterStage software products contain undetected errors or
       defects associated with the year 2000 problem;

     - third party hardware and software used with our CenterStage products
       experiences problems which are wrongly attributed to us;

     - our suppliers, internal information technology systems or non-information
       technology systems, including telecommunications systems and utilities,
       experience problems; and

     - our customers experience year 2000 problems.

     Although we have not to date experienced these problems to any significant
extent the occurrence of any of these problems later in the year 2000 is
possible and could result in delays or losses of revenues, diversion of our
development resources, damage to our reputation, increased service and warranty
costs and litigation costs. Our current or future customers may incur
significant expenses to achieve year 2000 compliance. If our customers are not
year 2000 compliant, they may experience material costs to remedy problems, they
may face litigation costs and they may delay purchases or implementation of our
CenterStage products. Year 2000 issues could reduce or eliminate the budgets
that current or potential customers could have for purchases of our CenterStage
products and related services. As a result, our revenues could be adversely
affected. Regardless of whether we experience year 2000 problems, enterprises
may reduce their spending on software and systems during early 2000 in
connection with the potential effects of the year 2000 or to concentrate their
resources on remediation. In addition, we may experience material problems and
costs with year 2000 compliance that could adversely affect our net operating
results. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Year 2000 Compliance." We have not developed a
contingency plan to address situations that may result if we are unable to
achieve year 2000 readiness of our critical operations or if our customers or
vendors encounter significant year 2000 compliance problems.

                         THE ONDISPLAY SPECIAL MEETING

DATE, TIME AND PLACE OF ONDISPLAY'S SPECIAL MEETING

     The date, time and place of the special meeting of OnDisplay stockholders
are as follows:

                                 March 30, 2000
                             9:00 a.m. Pacific Time
                       12667 Alcosta Boulevard, Suite 300
                          San Ramon, California 94583

PURPOSE OF THE SPECIAL MEETING

     The special meeting is being held so that OnDisplay stockholders may
consider and vote upon a proposal to approve issuance of OnDisplay common stock
in a merger with Oberon Software Incorporated that will cause Oberon to become a
wholly-owned subsidiary of OnDisplay. The meeting is also being held so that
OnDisplay stockholders may consider and vote upon a proposal to approve an
increase of the number of shares of common stock reserved for issuance of stock
options under the 1996 Stock Plan from 4,975,000 to 6,975,000 and such other
business as may properly come before the special meeting. The merger agreement
is included as Annex A to the attached proxy statement/prospectus. If the merger
is approved, among other things:

     - ObiOne Acquisition Corporation, a wholly-owned subsidiary of OnDisplay,
       will merge with and into Oberon.

     - OnDisplay will issue shares of common stock in the merger as contemplated
       by the merger agreement. OnDisplay will issue .0912 shares of OnDisplay
       common stock for each share of outstanding Oberon capital stock.

  RECORD DATE AND OUTSTANDING SHARES

     OnDisplay's board of directors has fixed the close of business on March 3,
2000 as the record date for the special meeting. Only holders of record of
OnDisplay common stock at the close of business on the record date are entitled
to notice of and to vote at the meeting. As of the close of business on the
record date, there were approximately 20,175,507 shares of OnDisplay common
stock outstanding and entitled to vote, held of record by approximately 177
stockholders.

VOTE AND QUORUM REQUIRED

     Under OnDisplay's certificate of incorporation and bylaws, and under
Delaware law, no vote of OnDisplay stockholders is required to approve the
merger and issuance of OnDisplay shares. However, because Mr. J. Mandile is a
director of both Oberon and OnDisplay and owns OnDisplay common stock, entities
affiliated with Matrix Partners are stockholders of both Oberon and OnDisplay
and one of the general partners of Matrix Partners serves as a director of
OnDisplay while another serves as a director of Oberon, a stockholder vote is
required under rule 4460(i) of the NASD rules relating to the Nasdaq Stock
Market.

     Holders of OnDisplay's common stock are entitled to one vote for each share
held as of the record date. Approval of each of the proposals to be voted upon
by OnDisplay stockholders requires the affirmative vote of a majority of the
common stock of OnDisplay present in person or represented by proxy at the
meeting. Attendance at the meeting in person or by proxy of a majority of the
outstanding common stock of OnDisplay is required for a quorum.

     THE HOLDERS OF APPROXIMATELY 54.2% OF THE OUTSTANDING SHARES OF ONDISPLAY
HAVE AGREED TO VOTE FOR APPROVAL OF THE ISSUANCE OF ONDISPLAY COMMON STOCK IN
THE MERGER. THEREFORE, THE REQUISITE STOCKHOLDER APPROVAL IS ASSURED.

                                       32
<PAGE>   39

     On the record date, directors, executive officers and affiliates of
OnDisplay as a group beneficially owned approximately 11,039,342 shares of
OnDisplay common stock, excluding any shares that may have been purchased by
affiliates since February 15, 2000.

ABSTENTIONS; BROKER NON-VOTES

     Abstentions will be included in determining the number of shares present
and voting at the meeting and will have the same effect as votes against these
proposals. In the event that a broker, bank, custodian, nominee or other record
holder of OnDisplay common stock indicates on a proxy that it does not have
discretionary authority to vote certain shares on a particular matter, which is
called 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.

EXPENSES OF PROXY SOLICITATION

     OnDisplay will pay the expenses of soliciting proxies to be voted at the
meeting. Following the original mailing of the proxies and other soliciting
materials, OnDisplay and its agents also may solicit proxies by mail, telephone,
telegraph or in person. Following the original mailing of the proxies and other
soliciting materials, OnDisplay will request brokers, custodians, nominees and
other record holders of OnDisplay common stock to forward copies of the proxy
and other soliciting materials to persons for whom they hold shares of OnDisplay
common stock and to request authority for the exercise of proxies. In such
cases, OnDisplay upon the request of the record holders, will reimburse such
holders for their reasonable expenses.

PROXIES

     The proxy accompanying this proxy statement/prospectus is solicited on
behalf of the OnDisplay board of directors for use at the meeting. Please
complete, date and sign the accompanying proxy and promptly return it in the
enclosed envelope or otherwise mail it to OnDisplay. All properly signed proxies
that OnDisplay receives prior to the vote at the meeting and that are not
revoked will be voted at the meeting according to the instructions indicated on
the proxies or, if no direction is indicated, to approve the issuance of
OnDisplay common stock in connection with the Oberon merger and increase of the
number of shares reserved under the 1996 Stock Plan.

REVOCABILITY OF PROXIES

     Unless you have signed a voting agreement, you may revoke your proxy at any
time before it is exercised at the meeting by taking any of the following
actions:

     - delivering a written notice to the secretary of OnDisplay by any means,
       including facsimile, bearing a date later than the date of the proxy,
       stating that the proxy is revoked;

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

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

     OnDisplay's board of directors does not know of any matter that is not
referred to in this proxy statement/prospectus to be presented for action at the
meeting. If any other matters are properly brought before the meeting, the
persons named in the proxies will have discretion to vote on such matters in
accordance with their best judgment.

                           THE OBERON SPECIAL MEETING

GENERAL: DATE, PLACE AND TIME

     This document is being furnished to holders of Oberon stock in connection
with the solicitation of proxies by the Oberon board of directors for use at the
special meeting of stockholders of Oberon to be held on March 30, 2000, at 10:00
a.m. local time at the headquarters of Oberon located at 215 First Street,
Cambridge, Massachusetts 02142, and at any adjournment or postponement of the
meeting.

MATTERS TO BE CONSIDERED

     At the special meeting, Oberon stockholders will be asked to consider and
vote upon a proposal to adopt and approve the merger agreement and the merger.

BOARD OF DIRECTORS' RECOMMENDATION

     A special committee of Oberon's board of directors, as well as the full
board, has unanimously approved the merger agreement and the merger and
recommends a vote FOR adoption of the merger agreement and approval of the
merger.

RECORD DATE

     Pursuant to Massachusetts law, the close of business on the next day
preceding the date on which notice is given is the record date for the special
meeting. Accordingly, only holders of Oberon capital stock of record at the
close of business will be entitled to notice of, and to vote at, the special
meeting.

STOCKHOLDERS ENTITLED TO VOTE

     As of the close of business on March 6, 2000, there were approximately
6,633,062 shares of common stock, 11,300,000 shares of series 1 convertible
participating preferred stock and 3,399,598 shares of series 2 convertible
non-participating preferred stock of Oberon outstanding and entitled to vote.
The holders of common stock are entitled to cast one vote for each share of
common stock they hold on each matter submitted to the common stockholders for a
vote at the special meeting. The holders of series 1 and 2 preferred stock are
entitled to cast one vote for each share of common stock into which their series
1 and 2 preferred stock, as the case may be, could then be converted on each
matter submitted to a vote at the special meeting. The presence in person or by
proxy of the holders of a majority of the shares of Oberon stock entitled to
vote is necessary to constitute a quorum for the transaction of business at the
special meeting.

REQUIRED VOTE

     Approval of the merger agreement under Massachusetts law and Oberon's
articles of organization requires the affirmative vote of the holders of:

     - at least two-thirds of the outstanding shares of common stock and shares
       of series 1 and 2 preferred stock voting as a single class on an as

PROXIES

     This document is being furnished to Oberon stockholders in connection with
the solicitation of proxies by the Oberon board of directors for use at the
special meeting, and is accompanied by a form of proxy.

     All shares of Oberon stock that are entitled to vote and are represented at
the Oberon special meeting by properly executed proxies received before or at
the meeting, and not revoked, will be voted at the meeting in accordance with
the instructions indicated on the proxies. If a proxy is properly executed but
no vote is specified, the proxy will be voted for adoption of the merger
agreement and approval of the merger, except for proxies submitted by record
holders of shares of Oberon stock who indicate that they have not received
voting instructions from the beneficial holders of those shares.

     If any other matters are properly presented for consideration at the Oberon
special meeting, the persons named in the enclosed form of proxy will have the
discretion to vote on those matters using their best judgment. Additional
matters which may come before the meeting include consideration of a motion to
adjourn the meeting to another time and/or place, which may be necessary for the
purpose of soliciting additional proxies from Oberon stockholders. The proxy
holders will not adjourn the meeting if there are insufficient votes to approve
the proposals at the date of the meeting.

REVOCABILITY OF PROXIES

     Any person who gives a proxy pursuant to this solicitation may revoke it at
any time before it is voted. To revoke a proxy, you must:

     - submit a later dated proxy with respect to the same shares at any time
       before the vote on the adoption of the merger agreement;

     - deliver written notice of revocation to the Clerk of Oberon at any time
       before the vote; or

     - attend the special meeting and vote in person.

     Your attendance at the special meeting alone is not sufficient to revoke a
proxy.

     Any written notice of revocation or subsequent proxy must be delivered at
or before the taking of the vote at the special meeting to Oberon Software
Incorporated, 215 First Street, Cambridge, Massachusetts 02142, Attention:
Clerk.

     If you have signed a voting agreement, you may not revoke your proxy.

SOLICITATION OF PROXIES

     The expense of the solicitation of proxies for the special meeting will be
borne by OnDisplay, including the cost of printing and mailing this document. In
addition to solicitation by mail, directors,

                                       35
<PAGE>   42

officers and employees of Oberon may solicit proxies in person or by telephone,
fax or other means of communications. These directors, officers and employees
will not receive additional compensation.

OBERON STOCKHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THEIR PROXY
CARDS.

                                APPRAISAL RIGHTS

     If the merger is completed, holders of Oberon capital stock who object to
the merger are entitled to appraisal rights under Massachusetts law. In order to
exercise appraisal rights, Oberon stockholders must strictly adhere to the
provisions of Massachusetts law governing appraisal rights. The following is a
summary of the relevant provisions of Massachusetts law. The description below
is only a summary and is qualified by reference to the relevant provisions of
Massachusetts law, a copy of which is attached hereto as Annex D.

     In order to exercise your appraisal rights, you must take the following
steps:

     - send a written objection to the merger to Oberon before the special
       meeting stating your intention to demand payment for your shares of
       Oberon capital stock if the merger is approved and the merger occurs;

     - do NOT vote in favor of the merger; and

     - send a written demand to Oberon for payment for your Oberon shares within
       twenty days after you received notice from Oberon that the merger has
       occurred. Oberon will send the notice within 10 days after the merger is
       completed.

     The written objection and written demand should be delivered to Oberon
Software Incorporated, 215 First Street, Cambridge, Massachusetts 02142,
Attention: Clerk. We recommend that you send the objection and demand by
registered or certified mail, return receipt requested.

     Please note that, if you file a written objection with Oberon prior to the
special meeting, you do not need to vote against the merger. However, if you
file a written objection with Oberon prior to the special meeting and vote in
favor of the merger, you will be deemed to have waived your right to exercise
appraisal rights.

     If you have followed the procedures set forth above and the merger is
completed, Oberon will contact you within 10 days after the effective time of
the merger in order to determine the fair value of your Oberon capital stock.
The "fair value" of your Oberon capital stock will be determined as of the day
before approval of the merger by the Oberon stockholders and will exclude any
value arising from the expectation of the merger. If Oberon and you have not
agreed as to the fair value of your stock within 30 days after you receive
notice from Oberon that the merger has occurred, both you and Oberon will have
the right to have the court determine the fair value by filing a bill in equity
in the Superior Court Department of Middlesex County, Massachusetts no later
than four months after the expiration of the negotiation period.

     After filing the bill in equity, the court or special master will hold a
hearing and enter a decree determining the fair value of your Oberon capital
stock and ordering Oberon to make payment to you of such value. You will also be
paid interest from the date of the special meeting to the time that you
surrender your certificates representing your shares of Oberon capital stock to
the exchange agent. The determination of fair value made by the court or special
master will be binding on and enforceable by you and the other Oberon
stockholders who have properly executed their appraisal rights.

     The fair value of the Oberon capital stock could be worth more than, the
same as, or less than the value of the OnDisplay common stock you would
otherwise have received by exchanging your shares of Oberon capital stock for
share of OnDisplay common stock.

                                       36
<PAGE>   43

     Your appraisal rights are your only remedy if you object to the merger,
unless the merger is determined to have been illegal, fraudulent or in breach of
the fiduciary duties of the Oberon board of directors.

     If you exercise your appraisal rights, after the merger is completed you
will not have any rights as an Oberon or OnDisplay stockholder, including the
right to receive notices of meetings, vote at meeting or receive dividends, if
any.

                               THE OBERON MERGER

     This section of the proxy statement/prospectus describes the proposed
Oberon merger. While we believe that the description covers the material terms
of the merger and the related transactions, 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 referred to for a more complete
understanding of the merger.

BACKGROUND OF THE OBERON MERGER AND RELATED AGREEMENTS

     OnDisplay is regularly involved in the review of private and public
companies with which it may form strategic partnerships to further its
objectives in the Internet commerce market. During the course of 1997, OnDisplay
was made aware of Oberon by J. Mandile, an OnDisplay director and an Oberon
director who is affiliated with Sigma Partners, a venture capital firm. In 1997
the two companies were in different markets with similar challenges. The Chief
Executive Officers of each company, M. Pine of OnDisplay and J. Chappell of
Oberon, were introduced and began a series of infrequent discussions on the
markets and the companies.

     On August 25, 1999, Mr. Pine met Mr. Chappell and certain executives at
Oberon's headquarters in Cambridge, Massachusetts to discuss potential strategic
opportunities for the two companies.

     On September 1, 1999, Mr. Pine invited Mr. Chappell to visit OnDisplay's
headquarters in San Ramon, California, to provide an overview of Oberon and
discuss strategic opportunities for the two companies. On September 9, 1999, Mr.
Chappell made a strategic overview presentation to the OnDisplay board of
directors on the potential benefits of a strategic partnership with Oberon.

     No further meetings or discussions ensued until December 16, 1999, when Mr.
Pine, who was in New York City on other business, met with Mr. Chappell for
breakfast. Mr. Pine invited Mr. Chappell to meet with OnDisplay management in
San Ramon and broaden the scope of the September discussions.

     At a December 20, 1999 meeting of the Oberon board of directors, Mr.
Chappell reviewed the discussions with Mr. Pine and the potential benefits of a
strategic relationship. Mr. Chappell was authorized to begin discussions with
OnDisplay about a potential business combination.

     On December 23, 1999, Mr. Pine and Mr. Chappell met with OnDisplay's V.
Mohan, Chief Operating Officer, S. Pierini, Vice President of Product Marketing,
and other managers of OnDisplay and Mr. Chappell presented an overview of
Oberon. Following the meeting, Mr. Pine and Mr. Chappell discussed the
possibility of a business combination and scheduled a visit to Cambridge,
Massachusetts for exchange of business and technical information.

     On January 4, 2000, OnDisplay and Oberon both signed a confidentiality
agreement.

     From January 4 through January 17, 2000 the two companies and their
respective financial and legal advisors conducted due diligence and negotiations
relating to a potential strategic relationship and proposed terms of the merger
agreement.

     At a January 10, 2000 meeting of the Oberon board of directors, Mr.
Chappell updated the directors concerning ongoing discussions with OnDisplay,
including a proposed merger in which OnDisplay would issue shares having a value
of approximately $200 million for all shares of Oberon capital stock and
options. The directors discussed the proposal and authorized a special committee
composed of all of the directors other than J. Mandile and M. Humphreys, a
general partner of Matrix Partners, to engage SoundView, as financial advisor,
and authorized the execution of a letter in which Oberon agreed not to engage in
any discussions with third parties with regard to possible business combinations
prior to January 20, 2000 and directed management to continue negotiations with
OnDisplay. Following this meeting, the special committee retained SoundView as a
financial advisor.

     On January 10, 2000, OnDisplay engaged Robertson Stephens, Inc. to provide
financial advisory services to OnDisplay in connection with a combination with
Oberon.

                                       38
<PAGE>   45

     On January 13, 2000, OnDisplay held a special board of directors meeting to
discuss the proposed business combination. At the outset of the meeting, J.
Mandile and T. Barrows, a general partner of Matrix Partners, were excused from
any discussions on the matter. The board of directors discussed the proposed key
terms of the transaction and the results of the investigations of Oberon by the
management and attorneys of OnDisplay. The board of directors received a
presentation from its financial advisor and authorized management to continue
discussions.

     On January 14, 2000, the Oberon special committee met to review a draft
merger agreement, including the representations and warranties, closing
conditions and indemnification and escrow provisions. Management was directed to
continue negotiations with OnDisplay.

     On January 16, 2000, the Oberon special committee met with its legal and
financial advisors. At this meeting, the special committee reviewed the terms of
the merger agreement and related agreements. Representatives of SoundView
reviewed the financial aspects of the proposed transaction and rendered an oral
opinion, subsequently confirmed in writing, that the terms of the proposed
transaction were fair, from a financial point of view, to the Oberon
stockholders. The special committee subsequently unanimously recommended
approval of the Oberon merger and merger agreement to the full Oberon board of
directors. At a meeting of the Oberon board immediately following the special
committee meeting, the Oberon board unanimously voted to approve the merger and
the merger agreement.

     On January 17, 2000, the OnDisplay board of directors met. At this meeting
the board of directors reviewed final terms of the transaction documents and
received from Robertson Stephens, Inc., its financial advisor, its oral opinion,
subsequently confirmed in writing, that the consideration to be paid by
OnDisplay in the merger was fair from a financial point of view, to OnDisplay.
Thereafter, the board of directors of OnDisplay, with J. Mandile and T. Barrows
excused, unanimously approved the merger and merger agreement.

     On January 18, 2000 prior to the opening of the Nasdaq Stock Market,
OnDisplay announced the execution of the merger agreement.

ONDISPLAY'S REASONS FOR THE MERGER

     In deciding to approve the merger and merger agreement, the OnDisplay board
concluded that acquiring Oberon was in the best interests of OnDisplay and its
stockholders. In reaching this decision, the OnDisplay board discussed and
considered several potential benefits created by the pending business
combination:

     - Merging with Oberon should expand the functionality and breadth of our
       product offerings to existing and prospective OnDisplay
       clients -- particularly, in fulfilling the need for business process
       automation software and application integration for business-to-business,
       business-to-consumer and electronic marketplace applications. OnDisplay
       should be able to integrate Oberon's eEnterprise software suite and broad
       selection of application adapters, or Oberon Building Blocks, into the
       OnDisplay product line. Oberon's software suite and Oberon Building
       Blocks represent a highly complementary solution to OnDisplay's existing
       CenterStage platform for e-business portals and e-marketplaces.

     - Using the combined product set, OnDisplay customers should be able to
       implement standard business processes -- including order acknowledgements
       and inventory status checks -- without the need to know which
       applications their trading partners have deployed, and without having to
       write code. When combined with our additional content aggregation,
       syndication and notification products, the integrated suite provides one
       of the industry's most comprehensive e-business infrastructure solutions.

     - Merging with Oberon should give OnDisplay a competitive advantage in the
       business-to-business integration market. The addition of Oberon's
       business process automation capabilities to OnDisplay's already strong
       aggregation, integration and exchange technologies creates one of the

                                       39
<PAGE>   46

       most comprehensive, easy to use, and high-performance e-business
       infrastructure software solutions on the market, thereby erecting a
       significant competitive barrier to other vendors.

     - Merging with Oberon will expand On Display's research and development
       resources, making available a stable and productive engineering team in
       Cambridge, Massachusetts, a visual software design environment and domain
       expertise in the business process automation and application integration
       market.

     The discussion of the information and factors considered by the OnDisplay
board is not intended to be exhaustive. In view of the variety of factors
considered in connection with its evaluation of the merger, the OnDisplay board
did not find it practicable to, and did not quantify or otherwise assign
relative weight to, the specific factors considered in reaching its
determination.

RECOMMENDATION OF ONDISPLAY'S BOARD OF DIRECTORS

     AFTER CAREFUL CONSIDERATION, THE ONDISPLAY BOARD OF DIRECTORS HAS
DETERMINED THE MERGER AGREEMENT AND THE MERGER TO BE FAIR TO AND IN THE BEST
INTERESTS OF ITS STOCKHOLDERS. IN CONNECTION WITH THE MERGER, ONDISPLAY'S BOARD
OF DIRECTORS, WITH THE EXCEPTION OF TWO DIRECTORS WHO WERE RECUSED FOR A
POTENTIAL CONFLICT OF INTEREST, RECOMMENDS APPROVAL OF THE ISSUANCE OF SHARES OF
ONDISPLAY COMMON STOCK IN THE MERGER AS DESCRIBED IN THIS PROSPECTUS/PROXY
STATEMENT.

OBERON'S REASONS FOR THE OBERON MERGER

     Oberon believes the following are reasons why the merger will be beneficial
to Oberon and its stockholders:

     - the exchange ratio;

     - the merger will enable Oberon to capitalize on OnDisplay's strong direct
       sales organization with proven marketing and distribution expertise in
       the e-business market, and the significant financial resources of
       OnDisplay will increase the visibility and accessibility of Oberon's
       products;

     - OnDisplay's research and development staff will enable Oberon to focus
       and accelerate its product development activities and OnDisplay's larger
       professional services staff will enable Oberon to accelerate its product
       implementation activities;

     - the merger will provide Oberon with immediate access to additional
       financial resources to accelerate its growth, as well as access to the
       public markets for further capital, if needed; and

     - the consideration to be paid to Oberon's stockholders in the merger will
       be shares of OnDisplay common stock, which are publicly traded on the
       Nasdaq National Market and more readily marketable than shares of Oberon
       stock.

RECOMMENDATION OF OBERON'S BOARD OF DIRECTORS

     AFTER CAREFUL CONSIDERATION, A SPECIAL COMMITTEE OF OBERON'S BOARD OF
DIRECTORS, AS WELL AS THE FULL BOARD OF DIRECTORS, UNANIMOUSLY DETERMINED THAT
THE MERGER IS IN THE BEST INTERESTS OF ITS STOCKHOLDERS AND UNANIMOUSLY APPROVED
THE MERGER AGREEMENT AND RECOMMEND THAT THE STOCKHOLDERS VOTE FOR APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT AND THE MERGER, AS DESCRIBED IN THIS
PROSPECTUS/PROXY STATEMENT.

     In considering the recommendation of a special committee of Oberon's board
of directors, as well as the full board of directors, with respect to the merger
agreement, you should be aware that some directors and officers of Oberon have
interests in the merger that are different from, or are in addition to the
interests of Oberon stockholders generally. Please see the section entitled
"Interests of Certain Directors, Officers and Affiliates in the Merger" on page
49 of this proxy statement/prospectus.

OPINION OF ONDISPLAY'S FINANCIAL ADVISOR (SEE APPENDIX B FOR A COPY OF THE FULL
OPINION)

     Under a letter agreement dated January 10, 2000, OnDisplay engaged
Robertson Stephens to render an opinion as to the fairness of the exchange
ratio, from a financial point of view, to OnDisplay.

     On January 16, 2000, at a meeting of the OnDisplay board held to evaluate
the proposed merger, Robertson Stephens delivered to OnDisplay's board its oral
opinion that, as of January 16, 2000 and based on the matters considered and the
limitations on the review undertaken described in the opinion, the 0.0912
exchange ratio was fair from a financial point of view to OnDisplay. Shortly
thereafter, Robertson Stephens delivered a written opinion, dated January 17,
2000 to the same effect. The 0.0912 exchange ratio was determined through
negotiations between the respective managements of OnDisplay and Oberon.
Robertson Stephens was not asked by, and did not recommend to, OnDisplay that
any specific exchange ratio constituted the appropriate exchange ratio for the
merger.

     You should consider the following when reading the discussion of the
opinion of OnDisplay's financial advisor in this document:

     - We urge you to read carefully the entire opinion of Robertson Stephens,
       which is set forth in appendix B to this proxy statement/prospectus and
       is incorporated by reference.

     - The following description of the Robertson Stephens opinion is qualified
       by reference to the full opinion located in appendix B to this proxy
       statement/prospectus. The full opinion sets forth, among other things,
       the assumptions made by Robertson Stephens, the matters it considered and
       the limitations on the review undertaken.

     - The Robertson Stephens opinion was prepared for the benefit and use of
       the OnDisplay board in its consideration of the merger and does not
       constitute a recommendation to stockholders of OnDisplay as to how they
       should vote at the special meeting, or take any other action, in
       connection with the merger.

     - The Robertson Stephens opinion does not address the relative merits of
       the merger and any other transactions or business strategies discussed by
       the OnDisplay board as alternatives to the merger agreement or the
       underlying business decision of the OnDisplay board to proceed with or
       effect the merger.

     Although developments following the date of the Robertson Stephens opinion
may affect the opinion, Robertson Stephens assumed no obligation to update,
revise or reaffirm its opinion. The Robertson Stephens opinion is necessarily
based upon market, economic and other conditions that were in effect on, and
information made available to Robertson Stephens as of, the date of the opinion.
You should understand that subsequent developments may affect the conclusion
expressed in the Robertson Stephens opinion, and that Robertson Stephens
disclaims any undertaking or obligation to advise any person of any change in
any fact or matter affecting its opinion. The Robertson Stephens opinion is
limited to the fairness, from a financial point of view and as of the date
thereof, of the 0.0912 exchange ratio to OnDisplay.

Opinion and Analysis of Robertson Stephens

     In connection with the preparation of the Robertson Stephens opinion,
Robertson Stephens:

     - reviewed certain internal financial statements and other financial and
       operating data, including certain financial forecasts and other forward
       looking information, concerning (a) Oberon prepared by the managements of
       Oberon and OnDisplay, respectively, and (b) OnDisplay prepared by the
       management of OnDisplay;

     - reviewed with OnDisplay certain publicly available research estimates of
       research analysts regarding OnDisplay;

     - held discussions with the respective managements of Oberon and OnDisplay
       concerning the businesses, past and current operations, financial
       condition and future prospects of both Oberon and
                                       41
<PAGE>   48

       OnDisplay, independently and combined, including discussions with the
       managements of Oberon and OnDisplay concerning their views regarding the
       strategic rationale for the merger;

     - reviewed the financial terms and conditions set forth in the draft merger
       agreement;

     - reviewed the stock price and trading history of OnDisplay common stock;

     - compared the financial performance of Oberon with that of certain
       publicly traded companies that it deemed comparable with Oberon;

     - compared the financial terms of the merger with the financial terms, to
       the extent publicly available, of other transactions that it deemed
       relevant;

     - reviewed the pro forma impact of the merger on OnDisplay's revenue per
       share and earnings per share;

     - prepared an analysis of the relative contributions of Oberon and
       OnDisplay to the combined company;

     - participated in discussions and negotiations among representatives of
       Oberon and OnDisplay and their financial and legal advisors; and

     - made such other studies and inquiries, and reviewed such other data, as
       it deemed relevant.

     In its review and analysis, and in arriving at its opinion, Robertson
Stephens assumed and relied upon the accuracy and completeness of all the
financial and other information provided to it (including information furnished
to it orally by the managements of OnDisplay and Oberon) or publicly available
and neither attempted independently to verify, nor assumed responsibility for
verifying, any of such information. Robertson Stephens relied upon the
assurances of the managements of OnDisplay and Oberon that they were not aware
of any facts that would make the information inaccurate or misleading.
Furthermore, Robertson Stephens did not make or obtain, or assume responsibility
for making or obtaining, any independent evaluation or appraisal of the
properties, assets or liabilities (contingent or otherwise) of OnDisplay or
Oberon, nor was it furnished with any such evaluations or appraisals.

     With respect to the financial forecasts and projections (and the
assumptions and bases therefor) for each of OnDisplay and Oberon that Robertson
Stephens reviewed, upon the advice of the managements of OnDisplay and Oberon,
Robertson Stephens assumed that:

     - these forecasts and projections were reasonably prepared in good faith on
       the basis of reasonable assumptions;

     - these forecasts and projections reflected the best currently available
       estimates and judgments as to the future financial condition and
       performance of OnDisplay and Oberon; and

     - these projections and forecasts would be realized in the amounts and in
       the time periods currently estimated.

     In addition, Robertson Stephens assumed that:

     - the merger will be consummated upon the terms set forth in the draft
       merger agreement made available to it without material alteration,
       including, among other things, that the merger will be accounted for as a
       "purchase method" business combination in accordance with United States
       generally accepted accounting principles;

     - the merger will be treated as a "reorganization" as defined in the
       Internal Revenue Code of 1986, as amended;

     - the historical financial statements of each of OnDisplay and Oberon
       reviewed by it were prepared and fairly presented in accordance with
       United States generally accepted accounting principles consistently
       applied; and

     - the exchange ratio will not be increased as a result of provisions of the
       draft merger agreement.
                                       42
<PAGE>   49

     Robertson Stephens relied as to all legal matters relevant to rendering its
opinion on the advice of its legal counsel.

     Robertson Stephens expressed no opinion as to:

     - the value of any employee agreement or other arrangements entered into in
       connection with the merger;

     - any tax or other consequences that may result from the merger; or

     - the value of OnDisplay common stock when issued to Oberon's stockholders
       in connection with the merger or the price at which shares of OnDisplay
       common stock may be traded in the future.

     The following is a summary of the material financial analyses performed by
Robertson Stephens in connection with rendering its opinion. The summary of the
financial analyses is not a complete description of all of the analyses
performed by Robertson Stephens. Certain of the information in this section is
presented in tabular form. IN ORDER TO BETTER UNDERSTAND THE FINANCIAL ANALYSES
PERFORMED BY ROBERTSON STEPHENS, THESE TABLES MUST BE READ TOGETHER WITH THE
TEXT OF EACH SUMMARY. THE ROBERTSON STEPHENS OPINION IS BASED ON THE TOTALITY OF
THE VARIOUS ANALYSES WHICH IT PERFORMED, AND NO PARTICULAR PORTION OF THE
ANALYSIS HAS ANY MERIT STANDING ALONE.

     Comparable Company Analysis. Using publicly available information,
Robertson Stephens analyzed, among other things, the trading multiples of
OnDisplay and the following selected publicly traded companies in the Internet
infrastructure software segment:

     - Active Software

     - BEA Systems

     - New Era of Networks

     - TIBCO

     - TSI Software

     - Vitria

     Revenues. As set forth in the following table, applying a range of
multiples for these companies for calendar years 1999 and 2000 to corresponding
revenue data for OnDisplay resulted in the following range of implied exchange
ratios and equity values for calendar years 1999 and 2000.

     Precedent Transaction Analysis. Robertson Stephens analyzed the aggregate
value and implied transaction value multiples paid or proposed to be paid in
selected precedent transactions in the Internet infrastructure software
industry, including:

     Mergent Systems, Inc./Commerce One (January 5, 2000)

     Signio/VeriSign (December 17, 1999)

     Tradex/Ariba (December 16, 1999)

     Trading Dynamics/Ariba (November 15, 1999)

     TheoryCenter/BEA Systems (November 10, 1999)

     Robertson Stephens compared, among other things, the aggregate value in
these transactions as a multiple of the preceding twelve months' revenues
("LTM"), the following 12 months' revenues ("NTM") and the number of employees.
Applying these multiples to similar revenue figures for OnDisplay resulted in
the following range of implied exchange ratios and implied equity values.
Revenue data was not publicly available for a number of the companies
represented in the selected precedent transactions.

     No company, transaction or business used in the Comparable Company Analysis
or the Selected Precedent Transaction Analysis as a comparison is identical to
OnDisplay, Oberon or the merger. Accordingly, an analysis of the results of the
foregoing is not entirely mathematical; rather it involves complex
considerations and judgments concerning differences in financial and operating
characteristics and other factors that could affect the acquisition, public
trading and other values of the comparable companies or the business segment,
company or transactions to which they are compared.

     Contribution Analysis. Robertson Stephens analyzed the respective
contributions of OnDisplay and Oberon to the estimated revenues of the combined
company for fiscal years 1999, 2000 and 2001. The

     Pro Forma Merger Analysis. Robertson Stephens analyzed the impact of the
merger on the revenues of the combined company for fiscal years 2000 and 2001
based on management estimates for OnDisplay and Oberon. The following table

     The actual results achieved by the combined company may vary from projected
results and such variations may be material.

     Other Factors. While this summary describes the analysis and factors that
Robertson Stephens deemed material in its presentation to the OnDisplay board,
it is not a comprehensive description of all analysis and factors considered by
Robertson Stephens. The preparation of a fairness opinion is a complex process
that involves various determinations as to the most appropriate and relevant
methods of financial analysis and the application of these methods to the
particular circumstances. Therefore, a fairness opinion is not readily
susceptible to partial analysis or summary description. In arriving at its
opinion, Robertson Stephens did not attribute any particular weight to any
analysis or factor considered by it, but rather made qualitative judgments as to
the significance and relevance of each analysis and factor. Accordingly,
Robertson Stephens believes that its analyses must be considered as a whole and
that selecting portions of its analyses and of the factors considered by it,
without considering all analyses and factors, could create a misleading or
incomplete view of the evaluation process underlying its opinion. Several
analytical methodologies were employed and no one method of analysis should be
regarded as critical to the overall conclusion reached by Robertson Stephens.
Each analytical technique has inherent strengths and weaknesses, and the nature
of the available information may further affect the value of particular
techniques. The conclusion reached by Robertson Stephens is based on all
analyses and factors taken as a whole and also on application of Robertson
Stephens' own experience and judgment. This conclusion may involve significant
elements of subjective judgment and qualitative analysis. Robertson Stephens
gives no opinion as to the value or merit standing alone of any one or more
parts of the analysis it performed. In performing its analyses, Robertson
Stephens made numerous assumptions with respect to industry performance, general
business and other conditions and matters many of which are beyond the control
of Oberon or Robertson Stephens. Any estimates contained in these analyses 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 these analyses. Accordingly, analyses relating to the value of businesses do
not purport to be appraisals or to reflect the prices at which these businesses
actually may be sold in the future, and these estimates are inherently subject
to uncertainty. Furthermore, no opinion is being expressed as to the prices at
which shares of OnDisplay common stock may be traded at any future time.

     OnDisplay's engagement letter with Robertson Stephens provides that, for
its services, Robertson Stephens is entitled to receive $500,000 due and payable
as follows: $250,000 in cash upon execution of the engagement letter and the
remaining $250,000 in cash upon delivery of the opinion, whether or not the
opinion is favorable. OnDisplay has also agreed to reimburse Robertson Stephens
for its out-of-pocket expenses and to indemnify and hold harmless Robertson
Stephens and its affiliates and any other person, director, employee or agent of
Robertson Stephens or any of its affiliates, or any person controlling Robertson
Stephens or its affiliates, for certain losses, claims, damages, expenses and
liabilities relating to or arising out of services provided by Robertson
Stephens as financial advisor to OnDisplay. The terms of the fee arrangement
with Robertson Stephens, which OnDisplay and Robertson Stephens believe are
customary in transactions of this nature, were negotiated at arm's length
between OnDisplay and Robertson Stephens, and the OnDisplay board was aware of
these fee arrangements.

     Robertson Stephens was retained based on Robertson Stephens' experience as
a financial advisor in connection with mergers and acquisitions and in
securities valuations generally, as well as Robertson Stephens' investment
banking relationship and familiarity with OnDisplay. Robertson Stephens has
provided financial advisory and investment banking services to OnDisplay from
time to time, including acting as lead managing underwriter for OnDisplay's
initial public offering. Robertson Stephens may actively trade the equity of
OnDisplay for its own account and for the account of its customers and,
accordingly, may at any time hold a long or short position in these securities.

     Robertson Stephens is an internationally recognized investment banking
firm. As part of its investment banking business, Robertson Stephens is
frequently engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of securities, private placements and other purposes.

OPINION OF OBERON'S FINANCIAL ADVISOR

     SoundView Technology Group was retained by the special committee of the
board of directors of Oberon to render an opinion as to whether the exchange
ratio to be offered in the merger is fair, from a financial point of view, to
the Oberon stockholders.

     On January 16, 2000, SoundView delivered its opinion to the special
committee of the board of directors of Oberon that, as of such date, based upon
the facts and circumstances as they existed at that time, and subject to certain
assumptions made, matters considered and limits of review set forth therein, the
exchange ratio to be offered in the merger is fair, from a financial point of
view, to the Oberon stockholders.

     The full text of the written opinion of SoundView, dated January 16, 2000,
which sets forth, among other things, the assumptions made, matters considered,
and the scope and limitations of the review undertaken and procedures followed
by SoundView in rendering its opinion, is included in Appendix C to this proxy
statement/prospectus. SoundView's opinion is directed only to the fairness of
the exchange ratio to be offered in the merger, from a financial point of view,
to the Oberon stockholders. SoundView's opinion was delivered for the use and
benefit of the special committee of the board of directors of Oberon in its
consideration of the Merger and is not intended to be and does not constitute a
recommendation to any Oberon stockholder as to how such stockholder should vote
with respect to the proposed merger. The summary of the opinion of SoundView set
forth below is qualified by reference to the full text of the opinion. Oberon
stockholders are urged to read this opinion in its entirety.

     In connection with rendering its opinion, SoundView, among other things:

     (i)    reviewed the Agreement and Plan of Reorganization and the specific
            terms of the merger set forth therein, and have assumed that the
            final form of the Agreement and Plan of Reorganization would not
            vary in any regard that is material to its analysis;

     (ii)   reviewed Oberon's financial and operating information for the
            two-year period ended September 30, 1999 and the three-month period
            ended December 31, 1999;

                                       46
<PAGE>   53

     (iii)  reviewed OnDisplay's financial and operating information for the
            three year period ended December 31, 1999;

     (iv)   reviewed certain financial and operating information regarding the
            businesses, operations and prospects of Oberon and OnDisplay,
            including forecasts and projections, provided to us by the
            managements of Oberon and OnDisplay, respectively;

     (v)   reviewed certain publicly available financial information concerning
           certain other companies it deemed to be reasonably similar to Oberon
           and OnDisplay and the trading markets for certain of such companies'
           securities;

     (vi)  reviewed the financial terms of the merger and compared them with the
           financial terms, to the extent publicly available, of certain recent
           mergers and acquisitions that it deemed relevant;

     (vii)  conducted discussions with certain members of senior management of
            Oberon and OnDisplay concerning their respective businesses and
            operations, assets, present condition and future prospects; and

     (viii)  performed such other analyses, examinations and procedures,
             reviewed such other agreements and documents, and considered such
             other factors as it deemed, in its sole judgment, to be necessary,
             appropriate or relevant to render its opinion.

     SoundView also took into account its assessment of general economic, market
and financial conditions and its experience in similar transactions, as well as
its experience in securities valuation in general. Its opinion is necessarily
based upon conditions as they existed and could be evaluated as of January 16,
2000.

     In arriving at its opinion, SoundView did not make, obtain or assume any
responsibility for any independent evaluation or appraisal of the properties and
facilities or of the assets and liabilities, contingent or otherwise of either
Oberon or OnDisplay. SoundView assumed and relied upon the accuracy and
completeness of the financial and other information supplied to or otherwise
used by it in arriving at its opinion, and did not attempt independently to
verify, or undertake any obligation to verify, such information. SoundView
further relied upon the assurances of the managements of Oberon and OnDisplay
that they were not aware of any facts that would make such information
inaccurate or misleading. In addition, SoundView assumed that the forecasts and
projections provided to it by OnDisplay and Oberon represented the best
currently available estimates and judgments of OnDisplay's and Oberon's
managements as to the future financial condition and results of operations of
OnDisplay and Oberon, respectively, and assumed that such forecasts and
projections were reasonably prepared based on such currently available estimates
and judgments. SoundView assumed no responsibility for and expressed no view as
to such forecasts and projections or the assumptions on which they were based.

     SoundView did not express any view as to the price at which OnDisplay's
stock will trade prior to or subsequent to the closing of the merger. Its
opinion did not constitute a recommendation of the merger over any other
alternative transactions which may have been available to Oberon and did not
address the underlying business decision of the special committee of the board
of directors of Oberon to proceed with or effect the merger.

     The following is a brief summary of all material aspects of the analyses
performed by SoundView in connection with rendering its opinion.

Analyses Relating to Oberon:

Analysis of Selected Comparable Publicly Traded Companies

     Using publicly available information, SoundView compared certain financial,
market and operating information of selected publicly traded enterprise
application integration vendors that were, in SoundView's judgment, similar to
Oberon. Companies analyzed by SoundView in connection with this analysis were
Active Software, Inc., BEA Systems, Inc., IONA Technologies plc, New Era of
Networks, Inc., Persistence Software, Inc., Tibco Software Inc., TSI
International Software Ltd. and Vitria Technology, Inc. For each of

                                       47

the selected companies, SoundView calculated a multiple of market capitalization
to projected calendar 2000 and 2001 revenues and a multiple of market
capitalization to one-year forward revenues at the time of that company's
initial public offering. The table below sets forth the results of such
analysis.

Comparable Transaction Analysis

     Using publicly available information, SoundView analyzed the purchase
prices and multiples paid in selected acquisitions of enterprise application
integration software vendors that, in SoundView's judgment, were comparable to
the business of Oberon. However, SoundView noted that none of such acquisitions
took place under market conditions or competitive conditions or circumstances
that are directly comparable to a merger as of the date of SoundView's opinion
and that, accordingly, qualitative judgments must be made concerning the
difference between the characteristics of these transactions and other factors
and issues which would affect the price an acquiror is willing to pay in an
acquisition. For each of the selected targets, SoundView calculated a multiple
of transaction value to LTM revenue. Transaction value was calculated by adding
net debt to the company's market capitalization. Net debt was calculated by
subtracting cash and cash equivalents from total debt. SoundView analyzed 11
transactions that were completed between December 27, 1997 and December 27,
1999. The table below sets forth the results of such analysis.

Analysis of Selected Comparable Publicly Traded Companies

     Using publicly available information, SoundView analyzed certain financial,
market and operating information of selected publicly traded Internet
infrastructure companies that were, in SoundView's judgment, similar to
OnDisplay. Companies analyzed by SoundView were Allaire Corporation, Art
Technology Group, Inc., Bluestone Software, Inc., BroadVision, Inc., InterWoven,
Inc., Open Market, Inc. Tibco Software Inc. and Vignette Corporation. For each
of the selected companies, SoundView calculated a multiple of market

Implied Exchange Ratio Analysis

     SoundView calculated ranges of implied exchange ratios using the implied
share prices of OnDisplay and Oberon. SoundView derived implied market
capitalizations for Oberon and OnDisplay from the comparable company analyses
discussed above and from OnDisplay's multiple of market capitalization calendar
2000 revenue as of January 13, 2000, respectively. SoundView then derived an
implied market capitalization of Oberon from the comparable company analyses
discussed above and discounted this market capitalization by a range of private
company discounts between 30% and 50%. Based on calendar 2000 revenue multiples
and an implied market capitalization for OnDisplay based on the comparable
company analyses, the analysis implied an exchange ratio range of 0.10225 to
0.14315. Assuming OnDisplay's multiple of market capitalization to calendar 2000
revenue as of January 13, 2000, the analysis implied an exchange ratio range of
0.07189 to 0.10065.

     In arriving at its opinion and in discussing its opinion with Oberon's
special committee of the board of directors, SoundView performed various
financial analyses. While the foregoing summary describes all material analyses
and factors considered by SoundView in rendering its opinion, such summary does
not purport to be a complete description of SoundView's analyses. SoundView
believes that its analyses and summaries should be considered as a whole, and
that selecting portions of its analyses or the factors considered by it, without
considering all factors and analyses, could create a misleading view of the
process underlying its opinion. The preparation of a fairness opinion is a
complex process and is not necessarily susceptible to partial analyses and
summary description. In performing its analyses, SoundView considered general
economic, market and financial conditions and other matters, many of which are
beyond the control of Oberon and OnDisplay. The analyses performed by SoundView
are not necessarily indicative of actual values or future results, which may be
significantly more or less favorable than those suggested by such analyses.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty.

     SoundView is a nationally recognized investment banking firm. As part of
its investment banking services, SoundView is frequently engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions, underwritings, secondary distributions of securities, private
placements and valuations for estate, corporate and other purposes. SoundView
was retained by the special committee of the Oberon board of directors to act as
its financial advisor in connection with the merger based upon SoundView's
experience as a financial advisor in mergers and acquisitions as well as
SoundView's familiarity with the enterprise application integration and Internet
infrastructure industries.

     SoundView was retained by the Oberon special committee pursuant to an
engagement letter dated January 10, 2000. Oberon agreed to pay SoundView a fee
of $290,000, one half at the time of the agreement and one half at the time the
fairness opinion was rendered. Oberon has also agreed to indemnify and hold
harmless SoundView and its affiliates and any other person, director, employee
or agent of SoundView or any of its affiliates, or any person controlling
SoundView or its affiliates, for certain losses, claims, damages, expenses and
liabilities arising out of services provided by SoundView as financial advisor
to Oberon.

     Except as described above, SoundView has not rendered material financial
advisory or investment banking services to Oberon or to OnDisplay during the
last three years. In the ordinary course of its business, SoundView may actively
trade in the equity securities of OnDisplay for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in such security.

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

     When considering the recommendation of the special committee of Oberon's
board of directors, as well as the full board of directors, you should be aware
that certain Oberon directors and officers have interests in the merger that are
different from, or are in addition to, your interests. The Oberon board of
directors was aware of these potential conflicts and considered them.

OnDisplay. In addition, as of February 15, 2000, J. Mandile holds 145,551 shares
of common stock of OnDisplay.

     Oberon Stock Options and Common Stock Subject to Repurchase. Assuming the
merger is completed on February 29, 2000, options to purchase an aggregate of
approximately 578,000 shares of Oberon common stock granted to directors and
executive officers of Oberon will accelerate upon the completion of the merger.
The foregoing amounts do not include options that have been or may be issued by
Oberon after December 31, 1999.

     The option acceleration and termination of repurchase rights for the
executive officers and directors of Oberon are set forth below as of December
31, 1999, assuming the merger occurs on February 29, 2000.

     Employment Agreements. M. McMahon and M. Wick have agreed to be employees
of OnDisplay after completion of the merger. They have executed employment
agreements with OnDisplay that become effective upon the completion of the
merger and terminate two years after the merger. Each of these agreements
provides for the following:

     - a minimum of six months severance payments unless the employee's
       termination is for cause or at the election of the employee;

     - each employee is entitled to participate in the employee benefit plans
       and programs of OnDisplay; and

     - each employee shall be considered for any employee bonus program,
       including retention bonus programs.

     Severance Agreements. Certain officers of Oberon have entered into
severance agreements with Oberon including J. Chappell and D. Collard. J.
Chappell's agreement provides for the following:

     - $150,000 in severance pay paid in one lump sum payment on the date of
       termination of his employment;

     - each outstanding option to purchase shares of common stock becoming
       immediately exercisable and each outstanding restricted stock award fully
       vesting on the date of termination of his employment; and

     - eligibility for continuing benefits under COBRA and reimbursement for
       COBRA premiums until the earlier of one year from termination of his
       employment or the loss of COBRA eligibility.

        D. Collard's agreement provides for the following:

     - $70,000 in severance pay paid in one lump sum payment on the date of
       termination of his employment;

                                       51
<PAGE>   58

     - each outstanding option to purchase shares of common stock becoming
       immediately exercisable and each outstanding restricted stock award fully
       vesting on the date of termination of his employment; and

     - eligibility for continuing benefits under COBRA and reimbursement for
       COBRA premiums until the earlier of six months from termination of his
       employment or the loss of COBRA benefits.

     Retention Options. Pursuant to the merger agreement, on January 16, 2000
Oberon granted options to certain of its employees, including M. McMahon and M.
Wick, to acquire shares of Oberon common stock. These options have an exercise
price of $2.50 per share and become exercisable as to 50% of the shares subject
to options on the first anniversary of the merger, with the balance becoming
exercisable over the next 36 months. M. McMahon was granted options to purchase
305,789 shares and M. Wick was granted options to purchase 175,000 shares.

INDEMNIFICATION AND INSURANCE

     The merger agreement provides that for six years after the completion of
the merger, OnDisplay will not alter or impair any exculpatory or
indemnification provision now existing in the Oberon bylaws. In addition, the
merger agreement provides that OnDisplay will fulfill and honor in all respects
the obligations of Oberon pursuant to Oberon's articles of organization and
bylaws and any indemnification agreements between Oberon of its respective
directors and officers existing prior to the closing of the merger. Oberon has
entered into indemnification agreements with each of its directors and with J.
Chappell, D. Collard, M. McMahon and M. Wick.

     Insofar as indemnification for liabilities arising under the Securities Act
or 1933 is permitted to directors or officers, the companies have been informed
that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed on the Act and is therefor
unenforceable.

COMPLETION AND EFFECTIVENESS OF THE MERGER

     The merger will be completed when all of the conditions to completion of
the merger are satisfied or waived, including approval and adoption of the
merger agreement and the merger by the stockholders of Oberon and approval of
the issuance of OnDisplay common stock in the merger by stockholders of
OnDisplay. The merger will become effective upon the filing of the certificate
of merger with the State of Massachusetts.

STRUCTURE OF THE MERGER AND CONVERSION OF OBERON COMMON STOCK

     Pursuant to the merger agreement, ObiOne Acquisition Corporation, a
wholly-owned subsidiary of OnDisplay, will merge with and into Oberon. Oberon
will then be a wholly-owned subsidiary of OnDisplay.

     Upon completion of the Oberon merger, each outstanding share of Oberon
capital stock will be converted into the right to receive .0912 shares of
OnDisplay common stock. No fractional shares of OnDisplay common stock will be
issued pursuant to the merger. In lieu of the issuance of any fractional shares
of OnDisplay common stock, OnDisplay will distribute cash equal to the product
of any fractional share amount, after aggregating all fractional shares
otherwise due to such holder otherwise due to a former Oberon stockholder and
$91.575.

EXCHANGE OF OBERON STOCK CERTIFICATES FOR ONDISPLAY STOCK CERTIFICATES

     When the Oberon merger is completed, OnDisplay's exchange agent will mail
to Oberon stockholders a letter of transmittal and instructions for use in
surrendering Oberon stock certificates in exchange for OnDisplay stock
certificates. When you deliver your Oberon stock certificates to the exchange
agent along with an executed letter of transmittal and any other required
documents, your Oberon stock certificates will be canceled and you will receive
OnDisplay stock certificates representing the number of full shares of OnDisplay
common stock to which you are entitled under the merger agreement. You will
receive
                                       52
<PAGE>   59

payment in cash, without interest, in lieu of any fractional shares of OnDisplay
common stock which would have been otherwise issuable to you in the merger.

     OBERON STOCKHOLDERS SHOULD NOT SUBMIT THEIR OBERON STOCK CERTIFICATES FOR
EXCHANGE UNTIL THEY RECEIVE THE TRANSMITTAL INSTRUCTIONS AND A FORM OF LETTER OF
TRANSMITTAL FROM THE EXCHANGE AGENT.

NO DIVIDENDS

     Oberon stockholders are not entitled to receive any dividends or other
distributions on OnDisplay common stock until the Oberon merger is completed and
they have surrendered their Oberon stock certificates in exchange for OnDisplay
stock certificates.

     Subject to the effect of applicable laws, promptly following surrender of
Oberon stock certificates and the issuance of the corresponding OnDisplay
certificates, Oberon stockholders will be paid the amount of dividends or other
distributions, without interest, with a record date after the completion of the
merger which were previously paid with respect to their whole shares of
OnDisplay common stock. At the appropriate payment date, Oberon stockholders
will also receive the amount of dividends or other distributions, without
interest, with a record date after the completion of the merger and a payment
date after they exchange their Oberon stock certificates for OnDisplay stock
certificates.

     OnDisplay will only issue Oberon stockholders an OnDisplay stock
certificate or a check in lieu of a fractional share in a name in which the
surrendered Oberon stock certificate is registered. If Oberon stockholders wish
to have their certificates issued in another name they must present the exchange
agent with all documents required to show and effect the unrecorded transfer of
ownership and show that they paid any applicable stock transfer taxes.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS OF THE OBERON MERGER

     In the opinion of Wilson Sonsini Goodrich & Rosati, PC, and Hale and Dorr
LLP, the following are the material United States federal income tax
consideration of the merger assuming that the merger is effected as described in
the merger agreement and in this proxy-statement prospectus. These opinions and
the following discussion are based on and subject to the Internal Revenue Code
of 1986, as amended, the regulations promulgated under the Internal Revenue
Code, existing administrative rulings and court decisions, all of which are
subject to change, possibly with retroactive effect, and assumptions,
limitations, representations and covenants, including those contained in
certificates of officers of OnDisplay and Oberon. We do not discuss all United
States federal income tax considerations that may be relevant to you in light of
your particular circumstances or if you are subject to special rules. Factors
which could alter the tax consequences of the merger to you include:

     - if you are a dealer in securities;

     - if you are subject to the alternative minimum tax provisions of the
       Internal Revenue Code;

     - if you are a foreign person or entity;

     - if you are a financial institution or insurance company;

     - if you do not hold your Oberon shares as capital assets;

     - if you acquired your shares in connection with stock option or stock
       purchase plans or in other compensatory transactions;

     - if you hold Oberon capital stock as part of an integrated investment,
       including a "straddle," comprised of shares of Oberon capital stock and
       one or more other positions; or

     - if you hold Oberon capital stock subject to the constructive sale
       provisions of Section 1259 of the Internal Revenue Code.

                                       53
<PAGE>   60

     In addition, we do not discuss the tax consequences of the merger under
foreign, state or local tax laws, the tax consequences of transactions
effectuated prior or subsequent to, or concurrently with, the merger whether or
not any such transactions are undertaken in connection with the merger,
including, without limitation, any transactions in which Oberon shares are
acquired or shares of OnDisplay are disposed of, or the tax consequences to
holders of options, warrants or similar rights to acquire Oberon capital stock.

     The obligations of OnDisplay and Oberon to complete the merger are
conditioned on, among other things, the receipt by OnDisplay of an opinion from
Wilson Sonsini Goodrich & Rosati, PC and the receipt of an opinion by Oberon
from Hale and Dorr LLP, in each case dated as of the completion of the merger
and stating that the merger will constitute a reorganization within the meaning
of Section 368(a) of the Internal Revenue Code. Alternatively, this condition
also will be satisfied upon the delivery of such tax opinion to OnDisplay and
Oberon from either Wilson Sonsini Goodrich & Rosati, PC or Hale and Dorr LLP.
The opinions of counsel to be provided at the completion of the merger will be
based on the existing law, will assume the absence of changes in existing facts,
and will rely on assumptions, representations and covenants including those
contained in certificates executed by officers of OnDisplay, ObiOne Acquisition
Corporation and Oberon. The opinions neither bind nor preclude the Internal
Revenue Service from adopting a contrary position, and it is possible that the
Internal Revenue Service may assert successfully a contrary position in
litigation or other proceedings. Neither OnDisplay nor Oberon intends to obtain
a ruling from the Internal Revenue Service with respect to the tax consequences
of the merger.

     In the opinion of counsel to OnDisplay and Oberon, the following material
federal income tax consequences will result from the merger constituting a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code:

     - You will not recognize any gain or loss upon your receipt of OnDisplay
       common stock in the merger, except on cash received for a fractional
       share of OnDisplay common stock.

     - The aggregate tax basis of the OnDisplay common stock received by you in
       the merger, including any fractional share of OnDisplay common stock not
       actually received, will be the same as the aggregate tax basis as the
       Oberon capital stock surrendered in exchange therefor.

     - If you hold your Oberon shares as a capital asset at the time of the
       merger, the holding period of the OnDisplay common stock received by you
       in the merger will include the period for which the Oberon capital stock
       surrendered in exchange therefor was considered to be held.

     - Cash payments received by you for a fractional share of OnDisplay common
       stock will be treated as if such fractional share had been issued in the
       merger and then redeemed by OnDisplay. You will recognize gain or loss
       with respect to such cash payment, measured by the difference, if any,
       between the amount of cash received and the basis in such fractional
       share.

     - You will be treated as having received the OnDisplay common stock
       deposited into the escrow fund upon consummation of the merger. Until
       such shares are released, the interim basis of the OnDisplay stock you
       received will be determined as though you received the maximum number of
       shares of OnDisplay. You will not recognize gain or loss and no amount
       will be included in your income by reason of the release of the OnDisplay
       shares from escrow. However, you may recognize gain or loss upon the
       return of such shares to OnDisplay. If gain is recognized, the value of
       such returned shares will be added to the tax basis of the OnDisplay
       common stock you retain.

     - You will recognize gain or loss if you exercise appraisal rights and
       receive payment for Oberon capital stock in cash, measured by the
       difference, if any, between the amount of cash received and the basis in
       such shares, provided that the payment is not treated as a dividend
       distribution for tax purposes. An appraisal rights payment should not be
       treated as a dividend distribution if, after the payment, you own no
       shares of OnDisplay or Oberon, actually or constructively.

     - OnDisplay, ObiOne Acquisition Corporation and Oberon will not recognize
       gain or loss solely as a result of the merger.

                                       54
<PAGE>   61

     Even if the merger qualifies as a reorganization, you could recognize gain
to the extent that shares of OnDisplay common stock are considered to be
received in exchange for services or property, other than solely for Oberon
capital stock. All or a portion of such gain may be taxable as ordinary income.
Gain also may have to be recognized to the extent that you are treated as
receiving, directly or indirectly, consideration other than OnDisplay common
stock in exchange for your Oberon capital stock.

     If the Internal Revenue Service successfully challenges the status of the
merger as a reorganization, you would recognize taxable gain or loss with
respect to each share of Oberon capital stock surrendered equal to the
difference between your basis in such share and (a) the fair market value, as of
the completion of the merger, of the OnDisplay common stock, and (b) cash in
lieu of a fractional share of OnDisplay common stock received in exchange
therefor. In such event, your aggregate basis in the OnDisplay common stock so
received would equal its fair market value as of the effective time of the
merger, and your holding period for such stock would begin the day after the
merger.

     THE FOREGOING DISCUSSION IS NOT INTENDED TO BE A COMPLETE ANALYSIS OR
DESCRIPTION OF ALL POTENTIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OR
ANY OTHER CONSEQUENCES OF THE MERGER. IN ADDITION, THE DISCUSSION DOES NOT
ADDRESS TAX CONSEQUENCES WHICH MAY VARY WITH, OR ARE CONTINGENT ON, YOUR
INDIVIDUAL CIRCUMSTANCES. ACCORDINGLY, WE URGE YOU TO CONSULT YOUR OWN TAX
ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE
APPLICABLE FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES TO YOU OF THE
MERGER.

TREATMENT OF OBERON COMMON AND PREFERRED STOCK

     In the merger, each share of Oberon capital stock will be exchanged for
shares of OnDisplay common stock.

     HOLDERS OF OBERON CAPITAL STOCK SHOULD NOT SEND THEIR OBERON CAPITAL STOCK
CERTIFICATES AT THIS TIME. FOLLOWING THE EFFECTIVE TIME OF THE MERGER, HOLDERS
OF OBERON CAPITAL STOCK WILL RECEIVE INSTRUCTIONS FOR THE SURRENDER AND EXCHANGE
OF SUCH STOCK CERTIFICATES.

ACCOUNTING TREATMENT OF THE MERGER

     OnDisplay intends to account for the merger as a "purchase" for financial
reporting and accounting purposes, under generally accepted accounting
principles.

REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE MERGER

     OnDisplay is not aware of any material governmental or regulatory approval
required for completion of the merger, other than the effectiveness of the
registration statement of which this proxy statement/prospectus is a part, and
compliance with applicable corporate laws of Massachusetts.

RESTRICTIONS ON SALES OF SHARES OF ONDISPLAY TO BE ISSUED IN THE MERGER

     The OnDisplay common stock to be received by the Oberon stockholders in the
merger may not be sold or otherwise transferred without the prior written
consent of OnDisplay until June 14, 2000. However, if OnDisplay stockholders
whose shares are restricted from transfer by agreements made in connection with
OnDisplay's initial public offering are permitted to sell their shares before
June 14, 2000, the former Oberon stockholders will also be permitted to sell at
that time.

     Ten percent of the OnDisplay shares of common stock to be received by the
holders of Oberon common stock and preferred stock will be deposited in an
escrow fund to serve security for indemnification of OnDisplay and its officers,
directors and affiliates against losses resulting from:

     - a breach or inaccuracy of a representation or warranty of Oberon in the
       merger agreement or an instrument delivered pursuant to the merger
       agreement;

     - Oberon's failure to perform or comply with a covenant in the merger
       agreement; and

     - expenses in excess of the amount estimated in the merger agreement.
                                       55
<PAGE>   62

     Escrowed shares that are not needed to satisfy indemnification claims made
within one year after the merger will be distributed to the former Oberon
stockholders.

     These shares may not be transferred during the one year period unless a
sale is effectuated through the stockholder representative, J. Chappell, and at
least $91.575 per share from the sale of such shares is placed in the escrow
fund in lieu of such shares.

     The shares of OnDisplay common stock to be issued in the merger will be
registered under the Securities Act. These shares will be freely transferable
under the Securities Act, except for shares of OnDisplay common stock issued to
any person who is an affiliate of Oberon. Persons who may be deemed to be
affiliates include individuals or entities that control, are controlled by, or
are under common control of Oberon and may include some of their respective
officers and directors, as well as their respective principal stockholders.
Affiliates may not sell their shares of OnDisplay common stock acquired in the
merger except pursuant to an effective registration statement under the
Securities Act covering the resale of those shares, an exemption under paragraph
(d) of Rule 145 under the Securities Act or any other applicable exemption under
the Securities Act.

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

     OnDisplay has agreed to cause the shares of OnDisplay common stock to be
issued in the merger to be approved for listing on Nasdaq.

Effective Time."

NO OTHER NEGOTIATIONS INVOLVING OBERON; SOLICITATION BY OBERON

     Until the merger is completed or the merger agreement is terminated, Oberon
has agreed not to, nor permit any of its officers, directors, affiliates,
employees, stockholders, agents or representatives to, directly or indirectly
take any of the following actions with any party other than OnDisplay and its
designees:

  - solicit, knowingly encourage, initiate or participate in any inquiry,
    negotiations or discussions, or enter into any agreement, with respect to
    any proposal to acquire any material part of Oberon's business, properties
    or technologies, or any material amount of Oberon's stock, whether or not
    outstanding; by merger, purchase of assets, tender offer, license or

     In the event Oberon receives any offer, proposal or request of the type

information as to the identity of the offeror and the specific terms of such
offer or proposal, and such other information related thereto as OnDisplay may
reasonably request.

OBERON'S EMPLOYEE BENEFIT PLANS

     OnDisplay has agreed, to the extent permitted by applicable law and
existing benefit plans and arrangements provided by Oberon are terminated after
completion of the merger, to provide benefits to Oberon employees that are on
parity with the benefits currently provided to employees of OnDisplay. Oberon
employees will get credit for all service with Oberon prior to the merger for
eligibility and vesting purposes and vacation accrual, to the extent possible.
With respect to any medical or dental benefit plan of OnDisplay, OnDisplay shall
waive any preexisting condition exclusion and actively-at-work requirements and
any covered expenses incurred before the merger will be taken into account for

<PAGE>   66

TREATMENT OF OBERON STOCK OPTIONS AND WARRANTS

     Upon completion of the merger, each outstanding option to purchase Oberon
common stock will be converted into an option to purchase the number of shares
of OnDisplay common stock adjusted based on the exchange ratio, rounded down to
the nearest whole number of shares. The exercise price will be equal to the
exercise price per share of Oberon common stock divided by the exchange ratio,
rounded up to the nearest whole cent. Upon completion of the merger, all
outstanding warrants to purchase Oberon common stock will be assumed by
OnDisplay, except that each warrant will be exercisable for the number of shares
of OnDisplay common stock adjusted based on the exchange ratio, rounded down to
the nearest whole number of shares. The exercise price of the warrants will be
equal to the exercise price per share for Oberon common stock divided by the
exchange ratio, rounded up to the nearest whole cent.

     Prior to the completion of the merger, outstanding purchase rights under
Oberon's Employee Stock Purchase Plan will be exercised, and each share of
Oberon common stock purchased will be converted into the right to receive a
number of shares of OnDisplay common stock equal to the exchange ratio in the
merger.

     OnDisplay will file a registration statement on Form S-8 for the shares of
OnDisplay common stock issuable with respect to options under the Oberon stock
option plans.

<PAGE>   68

ESCROW FUND

     Ten percent of the OnDisplay shares of common stock to be received by the
holders of outstanding Oberon common stock and preferred stock will be deposited
in an escrow fund for a period of one year to serve as security for
indemnification of OnDisplay and its officers, directors and affiliates against
losses resulting from:

     - any breach or inaccuracy of a representation or warranty of Oberon in the
       merger agreement or an instrument delivered pursuant to the merger
       agreement;

     - any failure by Oberon to perform or comply with a covenant in the merger
       agreement; or

     - Oberon incurring third party expenses in excess of the amount estimated
       in the merger agreement.

     Shares of OnDisplay common stock deposited on behalf of Oberon stockholders
into the escrow fund may not be transferred during the one year term of the
escrow fund unless the shares are sold by the stockholder representative on the
owner's behalf and at least $91.575 per share from the sale is placed in the
fund in lieu of the shares sold.

TERMINATION OF THE MERGER AGREEMENT

     The merger agreement may be terminated at any time prior to completion of
the merger:

     - By mutual written consent of OnDisplay and Oberon.

     - By OnDisplay or Oberon, if the merger is not completed before July 31,
       2000, except that this right of termination is not available to any party
       whose action or failure to act has been a principal cause of or resulted
       in the failure of the merger to occur on or before July 31, 2000, and
       such action or failure to act constitutes a breach of the merger
       agreement.

     - By OnDisplay or Oberon, if there shall be a final order of any court in
       effect preventing consummation of the merger, or there shall be any
       statute, rule, regulation or order enacted, promulgated or issued that
       would make it illegal.

     - By OnDisplay if there shall be any action taken, or any statute, rule,
       regulation or order enacted, promulgated or issued by any governmental
       entity, which would prohibit OnDisplay's ownership or operation of any
       portion of Oberon's business or compel OnDisplay or Oberon to dispose of
       or hold separate all or any portion of their business or assets as a
       result of the merger.

     - By OnDisplay, upon a breach of any representation, warranty, covenant or
       agreement of OnDisplay contained in the merger agreement so that the
       corresponding condition to completion of the merger would not be met.
       However, if the breach or inaccuracy is curable by OnDisplay, Oberon may
       not terminate the merger agreement for 10 days after delivery of written
       notice from OnDisplay of the breach.

     - By Oberon, upon a breach of any representation, warranty, covenant or
       agreement of Oberon contained in the merger agreement so that the
       corresponding condition to completion of the merger would not be met.
       However, if the breach or inaccuracy is curable by Oberon, OnDisplay may
       not terminate the merger agreement for 10 days after delivery of written
       notice from Oberon of the breach.

EXTENSION, WAIVER AND AMENDMENT OF THE MERGER AGREEMENT

     OnDisplay, Oberon and J. Chappell, as representative at the Oberon
stockholders, may amend the merger agreement before completion of the merger by
unanimous written consent.

     Either OnDisplay or Oberon may, to the extent legally allowed, in writing,
extend the other's time for the performance of any of the obligations or other
acts under the merger agreement, waive any inaccuracies in the other's
representations and warranties and waive compliance by the other with any of the
agreements or conditions contained in the merger agreement, prior to completion
of the merger.

                        AGREEMENTS RELATED TO THE MERGER

     This section of the proxy statement/prospectus describes agreements related
to the merger agreement, including the OnDisplay voting agreements and the
Oberon voting agreements. While we believe that these descriptions cover the
material terms of these agreements, these summaries may not contain all of the
information that is important to you.

ONDISPLAY VOTING AGREEMENTS

     As a condition to Oberon's entering into the merger agreement, Oberon and
each of Matrix IV Entrepreneurs Fund, L.P., Matrix IV Management Co. L.L.C.,
Atlas Venture Fund II, L.P., O. Sermet, D. Larson, M. Pine, V. Mohan, T. Dung,
Norwest Venture Partners VI, M. Deppe, M. Taylor, and C. Villani entered into
voting agreements. By entering into the voting agreements these OnDisplay
stockholders have irrevocably appointed Oberon as their lawful attorney and
proxy. These proxies give Oberon the limited right to vote the shares of
OnDisplay common stock beneficially owned by these OnDisplay stockholders,
including shares of OnDisplay common stock acquired after the date of the voting
agreements, in favor of issuance of shares of OnDisplay common stock in the
merger in accordance with the merger agreement. These OnDisplay stockholders may
vote their shares of OnDisplay common stock on all other matters.

     As of the record date, 10,927,330 shares, all the shares owned by these
individuals, or approximately 54.2% of the outstanding OnDisplay common stock,
are subject to the voting agreement. None of the OnDisplay stockholders who are
parties to the voting agreements were paid any consideration in connection with
this agreement.

     Under these voting agreements, each of these OnDisplay stockholders agrees
not to sell the OnDisplay common stock and options owned, controlled or
acquired, either directly or indirectly, by that person until the earlier of the

OBERON VOTING AGREEMENT

     As a condition to OnDisplay's entering into the merger agreement, OnDisplay

IV Entrepreneurs Fund, L.P., Charles River VIII-A L.L.C., and Charles River
Partnership VIII entered into voting agreements. By entering into the voting
agreements these Oberon stockholders have irrevocably appointed OnDisplay as
their lawful attorney and proxy. These proxies give OnDisplay the limited right
to vote all the shares of Oberon capital stock beneficially owned by these
Oberon stockholders, including shares of Oberon common stock acquired after the
date of the voting agreements in favor of approval of the merger agreement as
modified or amended from time to time, and the merger and against any other
alternative transaction. These Oberon stockholders may vote their shares of
Oberon common stock on all other matters.

     As of March 6, 2000, these individuals and entities collectively
beneficially owned approximately 87.6% of the outstanding capital stock and 100%
of the series 1 and 64.7% of the series 2 preferred stock outstanding and have
agreed to vote their shares of Oberon capital stock in favor of the merger
agreement and the merger. None of the Oberon stockholders who are parties to the
voting agreements were paid additional consideration in connection with this
agreement.

     Under these voting agreements, each of these Oberon stockholders agreed not
to sell the Oberon common 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 the stockholder agreement 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 the voting agreement. These voting agreements will
terminate upon the earlier to occur of the termination of the merger agreement
and the completion of the merger.

AFFILIATE AGREEMENTS

     OnDisplay will be entitled to place appropriate legends on the certificates
evidencing any OnDisplay common stock to be received by these persons and to
issue stop transfer instructions to the transfer agent for the OnDisplay common
stock. These persons have acknowledged the resale restrictions imposed by Rule
145 under the Securities Act on shares of OnDisplay common stock to be received
by them in the merger. OnDisplay and Oberon have agreed to use commercially
reasonable efforts to cause its affiliates to execute affiliate agreements as
promptly as possible.

EMPLOYMENT AGREEMENTS

     M. McMahon and M. Wick have agreed to be employees of OnDisplay after
completion of the merger. They have executed employment agreements with
OnDisplay that become effective upon the merger and terminate two years after
the merger. Each of these agreements provides for the following:

     - a minimum of six months severance payments unless the employee's
       termination is for cause or at the election of the employee;

     - an agreement to enter into non-competition agreements;

     - each employee is entitled to participate in the employee benefit plans
       and programs of OnDisplay; and

     - each employee shall be considered for any employee bonus program,
       including retention bonus programs.

SEVERANCE AGREEMENTS

     Certain officers of Oberon have entered into severance agreements with
Oberon. These persons include J. Chappell and D. Collard. Mr. Chappell's
agreement provides for the following:

     - $150,000 in severance pay paid in one lump sum on the date of termination
       of his employment;

     - each outstanding option to purchase shares of common stock will
       accelerate and become immediately exercisable and each outstanding
       restricted stock award shall fully vest; and

     - eligibility for continuing benefits under COBRA and reimbursement for
       COBRA premiums until the earlier of one year from termination of his
       employment or the loss of COBRA eligibility.

     Mr. Collard's agreement provides for the following:

     - $70,000 in severance pay paid in one lump sum on the date of termination
       of his employment;

     - each outstanding option to purchase shares of common stock will
       accelerate and become immediately exercisable and each outstanding
       restricted stock award shall fully vest; and

     - eligibility for continuing benefits under COBRA or reimbursement for
       COBRA premiums until the earlier of six months from termination of his
       employment or the loss of COBRA eligibility.

     Indemnification and Insurance. The merger agreement provides that for six
years after the completion of the merger, OnDisplay will not alter or impair any
exculpatory or indemnification provision now existing in the Oberon bylaws. In
addition, the merger agreement provides that OnDisplay will fulfill and honor in
all respects the obligations of Oberon pursuant to Oberon's articles of
organization and bylaws relating to indemnification and any indemnification
agreements between Oberon and its respective directors and officers existing
prior to the closing of the merger. In connection with the merger agreement,
Oberon has entered into indemnification agreements with each of its directors
and with J. Chappell, D. Collard, M. McMahon and M. Wick.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 is permitted to directors or officers, the companies have been informed
that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is therefor
unenforceable.

                       COMPARISON OF RIGHTS OF HOLDERS OF
                            OBERON COMMON STOCK AND
                             ONDISPLAY COMMON STOCK

     This section of the proxy statement/prospectus describes certain
differences between Oberon capital stock and OnDisplay capital 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 Oberon
stockholders, including the certificate of incorporation and bylaws of OnDisplay
and the articles of incorporation and bylaws of Oberon. Oberon stockholders
should read this entire document and the other documents referred to carefully
for a more complete understanding of the differences between Oberon common stock
and OnDisplay common stock.

     Oberon's articles of incorporation and bylaws currently govern the rights
of stockholders of Oberon. After the completion of the Oberon merger, Oberon's
common stockholders will become stockholders of OnDisplay. As a result, former
Oberon stockholders' rights will be governed by OnDisplay's certification of
incorporation and bylaws. Furthermore, because OnDisplay is a Delaware
corporation, after the Oberon merger former Oberon stockholders' rights will be
governed by the Delaware General Corporation Law, rather than by Massachusetts
law. The following paragraphs summarize certain differences between the rights
of OnDisplay stockholders and Oberon stockholders under the certificate of
incorporation and bylaws of OnDisplay and articles of incorporation and bylaws
of Oberon, and under Delaware and Massachusetts law, as applicable.

INDUSTRY BACKGROUND

     Companies in all industries around the world face the strategic imperative
of re-creating themselves into electronic commerce, or e-commerce, companies. By
augmenting or even replacing their traditional distribution, supply chain and
customer-service channels with Internet-based channels, these companies seek to
build new revenue streams and gain competitive advantage. Although the first
generation of e-commerce consisted primarily of basic Web sites offering product
information for marketing purposes, today the stakes are higher. We believe
successful companies now need to create value-added relationships with suppliers
and distributors and offer differentiated and unique online services to
customers. By extending core business processes over the Internet and
integrating systems with suppliers, distributors and customers, these companies
seek to achieve significant competitive advantage, increased customer
satisfaction and new sources of revenues. This next generation of e-commerce,
often referred to as e-business, is transforming the way business is done and
has given rise to the "Internet economy."

     With the evolution of the Internet as a primary means of conducting
business, both in business-to-business and business-to-consumer markets,
competitive pressures have driven new and more sophisticated forms of e-commerce
to emerge. In the Internet economy, companies find it increasingly difficult to
differentiate their offerings on the basis of products, price or location. As a
result, vendors must deliver comprehensive business services and information to
offer enhanced value to their suppliers, distributors and customers. In
particular, companies seek to participate in two complementary e-business
channels -- e-business portals and e-marketplaces -- as distinct ways to
capitalize on the Internet, expand their businesses and protect their revenue
opportunities. These channels are complementary since many vendors will create
an e-business portal to directly sell their own goods and services in addition
to offering those goods and services through participation in an e-marketplace.

     E-BUSINESS PORTALS. An e-business portal is an online destination site
where vendors create value-added relationships with their suppliers,
distributors and customers by offering an expanded set of information and
services. For example, a business-to-consumer, travel-oriented e-business portal
enables visitors to gain information about all aspects of the travel experience,
including airfare, hotel availability, cultural activities, weather and current
events, and then purchase all of the goods and services for a particular trip
without having to leave the portal at any point in the process.

     E-MARKETPLACES. An e-marketplace is a comprehensive trading hub designed to
efficiently manage transactions and services among multiple buyers and sellers.
For example, a business-to-business e-marketplace acts as an intermediary to
enable businesses to interact with potentially thousands of discrete vendors,
compare parts, prices and configurations among those vendors, and then purchase
all of the goods and services from one or several vendors without having to
leave the e-marketplace at any point in the process.

                                       74
<PAGE>   81

     The Internet economy is poised for rapid growth, across both
business-to-business and business-to-consumer markets. According to Forrester
Research, the volume of business-to-business e-commerce transacted through
e-business portals, e-marketplaces and other e-business offerings will grow from
$43 billion in 1998 to $1.3 trillion in 2003.

     There are many demands placed on the infrastructure of e-business portals
and e-marketplaces. Companies deploying e-business portals and e-marketplaces
must be able to offer a broad range of dynamic information and services from a
large, diverse set of trading partners, and do so faster than their competitors.
Compounding this challenge is the fact that these e-business relationships
require agility in terms of flexible, adaptable connections that accommodate
rapid change. No single standard can be imposed on all suppliers of information
and services offered by e-business portals and e-marketplaces.

     To successfully address these business requirements, e-business portals and
e-marketplaces must meet complicated technical requirements. Key technical
requirements include:

     - Aggregation -- capturing and transforming diverse information from a
       broad range of sources and in multiple formats;

     - Integration -- integrating e-business portals and e-marketplaces with
       operational systems to synchronize and automate services and
       transactions; and

     - Exchange -- enabling the exchange of business documents, including
       purchase orders and invoices, for secure, real-time business process
       automation.

     Given these requirements, e-business portals and e-marketplaces face
significant challenges in effectively expanding their businesses to fully
capitalize on the opportunities created by the Internet. Existing approaches for
addressing these challenges are limited. The most common approaches consist of
manual, custom systems, which may be adequate initially, but tend to break down
as the e-business portals and e-marketplaces expand to provide additional
services and information from an ever-increasing number of suppliers,
distributors and customers. Many of these custom approaches incorporate
single-function products that address particular infrastructure needs but do not
offer a comprehensive solution that spans each of the important requirements.
These custom approaches often lack:

     - speed of deployment;

     - ability to accommodate growth to thousands of discrete participants;

     - agility to accommodate rapid change; and

     - comprehensiveness to meet the demands of a broad range of e-business
       relationships and interactions.

     As a result, there is a need for e-business infrastructure applications
that provide a comprehensive solution for enabling e-business portals and
e-marketplaces. This solution must be open, expandable to many concurrent users
and adaptable to enable the rapid aggregation, integration, and exchange of
dynamic information and services.

       and extend their market leadership.

       customers to be more agile in responding to the rapid pace of change
       associated with the Internet economy. By delivering an easy-to-use and
       highly flexible product suite, we provide our customers with the ability
       to handle a broad range of rapidly changing business relationships. Our
       solution is capable of growing to support thousands of participants,
       flexible to accommodate rapidly changing relationships and industry
       standards, and adaptable to manage disparate systems and ways of doing
       business.

ONDISPLAY STRATEGY

     Our objective is to become the leading provider of comprehensive e-business
infrastructure solutions that enable the creation of e-business portals and
e-marketplaces. Key elements of our strategy to achieve this objective are:

     - TARGET E-BUSINESS PORTAL AND E-MARKETPLACE MARKETS. We intend to
       establish our brand and expand market share in two large and growing
       e-business markets: e-business portals and e-marketplaces. In the
       e-business portal market we will target both traditional and
       Internet-based businesses across specific markets with critical and
       urgent e-business needs. Our strategy is to pursue industries that have a
       large number of fragmented buyers and sellers and conduct large amounts
       of commerce. At the same time, we intend to aggressively expand our
       presence in the e-marketplace market, which we believe represents a major
       opportunity as e-marketplace businesses become pioneers in the use of
       automated, robust and expandable information exchange solutions.

     - ADDITIONAL EXPOSURE THROUGH NETWORK EFFECTS. As our customers use our
       solution across their network of suppliers, buyers and other market
       participants, numerous other e-businesses become aware of our products
       and their features and are continually exposed to our products with
       subsequent exchanges of critical business information. We believe this
       allows participants in e-business transactions to experience the benefits
       that our products deliver first hand, which creates a powerful network
       effect to drive more rapid product recognition and adoption. We intend to
       take maximum advantage of this visibility across our targeted markets in
       order to drive increased sales.

     - CONTINUE OUR TECHNOLOGICAL INNOVATION. We intend to continue to innovate
       comprehensive e-business infrastructure solutions based on our technology
       and emerging industry standards. Our core CenterStage technology provides
       a powerful foundation for seamless information exchange among e-business
       participants. With each succeeding generation of our technology, we have
       extended this foundation and added features that increase the range of
       functions and ease-of-use of our solutions. For example, as the Internet
       becomes the preferred medium for business transactions of all types,
       companies are increasingly using extensible markup language, or XML, as
       the software protocol upon which to base their interactions with
       suppliers, distributors and customers. We intend

                                       76
<PAGE>   83

       to take advantage of this trend by continually enhancing our highly
       automated, easy-to-use XML solution.

     - BUILD UPON OUR NETWORK OF RELATIONSHIPS. We are building relationships
       with a variety of industry leading independent software vendors, platform
       providers and systems integrators. We intend to utilize and extend this
       network to reach target markets, accelerate the adoption of our
       technologies, and test and validate our next-generation product and
       technology. These relationships enable us to focus on our core
       competencies, while offering our customers highly complementary
       technologies from industry leaders and innovators. We believe that these
       relationships, in addition to others that we intend to pursue, will help
       validate and accelerate the widespread adoption of our e-business
       infrastructure solutions.

     - EXPAND OUR INTERNATIONAL PRESENCE. We intend to penetrate global markets
       by establishing a worldwide field sales, marketing, and services
       organization. We are currently establishing and staffing international
       headquarters and field sales offices in Europe. We also expect to
       establish relationships with international distributors and systems
       integrators.

PRODUCTS

     We provide an integrated solution for enabling the rapid deployment and
seamless management of e-business portals and e-marketplaces. Our products are
complementary, but can be purchased separately, so that online businesses can
select the individual products they need to meet their immediate business
objectives and then add additional CenterStage products as their requirements
evolve.

     The license fee for each CenterStage product is based on the number of
servers running the software and the number of different information sources
accessed. The list price of each CenterStage product starts at $75,000. License
fees for installations typically range from $100,000 to $400,000. The
CenterStage product suite includes:

     - CENTERSTAGE ECONTENT -- Our CenterStage eContent application enables our
       customers to aggregate, or gather, and transform a wide range of
       information, or content, for their e-business portals and e-marketplaces.
       Whether the source format is structured, as with database or application
       data, or unstructured, as with Web pages, CenterStage eContent lets users
       specify, select, transform, update and manage diverse content rapidly and
       easily. CenterStage eContent can handle high volumes of data, for
       example, aggregating text and graphics on hundreds of thousands of
       products. As a result, CenterStage eContent enables e-business portals
       and e-marketplaces to deliver a wide array of rich, relevant information
       to keep their customers from having to leave their Web sites to access
       this information.

       Travel portals, for example, use CenterStage eContent to pull up-to-date
       airline, hotel, cruise package, car rental and weather information onto
       their Web sites from hundreds of affiliated companies. By presenting
       customers with this pertinent and timely information, these travel
       portals are better able to engage and retain their customers and increase
       their bookings.

     - CENTERSTAGE EBIZXCHANGE -- Our CenterStage eBizXchange application takes
       advantage of advanced technologies to rapidly and securely exchange
       business transaction information across a wide array of trading partners.
       This information exchange can be accomplished across corporate security
       systems, or firewalls, using both "tight" and "loose" collaboration
       models. CenterStage eBizXchange's tight collaboration model allows
       business partners to define a standard approach for secure
       business-to-business information exchange, using a mutually agreed upon
       format. The product's loose collaboration model, enables the e-business
       to complete a transaction with its online trading partner by mimicking a
       user's actions on the trading partner's Web site, without the need for an
       explicit format agreement between the partners. CenterStage eBizXchange
       can handle thousands of transactions simultaneously, which enables our
       customers to expand their e-business applications to meet the needs of
       increasing numbers of users.

                                       77
<PAGE>   84

       Industrial supplies e-marketplaces, for example, use CenterStage
       eBizXchange to manage transactions among multiple buyers and sellers,
       using a range of transaction formats and protocols. These e-marketplaces
       use CenterStage eBizXchange to automatically request and route electronic
       business documents including purchase orders, requisitions, inventories
       and pick lists. These e-marketplaces may use tight collaboration for
       large buyers and suppliers, while they employ loose collaboration for
       smaller groups that might not have the resources to implement specific
       technology formats.

     - CENTERSTAGE eINTEGRATE -- Our CenterStage eIntegrate product provides a
       complete solution for linking the e-business portal or e-marketplace with
       its existing internal applications, including enterprise resource
       planning, or ERP, systems. This linking, or integration, enables the
       portal's customers, partners and suppliers to perform a range of
       functions on the Web-based portal, including placing an order with the
       source data, such as inventory availability, accessible from an internal
       system. CenterStage eIntegrate can handle thousands of internal
       application updates and data requests simultaneously, which enables our
       customers to expand their e-business applications to meet the needs of
       increasing numbers of users. CenterStage eIntegrate can use existing
       technologies, including popular message brokers, to request and route
       data. In addition, customers can purchase and use integration toolkits to
       create tighter links between their e-business portals and their internal
       applications, including those from Oracle, PeopleSoft and SAP.

       A computer and electronics portal, for example, may use CenterStage
       eIntegrate to process customer orders and enter these orders directly
       into the e-business's internal accounting system. The portal's customers
       could also check the status of their orders by accessing that information
       directly from the internal accounting system using CenterStage
       eIntegrate.

     - CENTERSTAGE eNOTIFY -- Our CenterStage eNotify product allows
       e-businesses to offer customer-requested updates, or alerts, to build
       relationships with their customers. Unlike many existing programs that
       track each user's behavior patterns to create targeted sales offers,
       CenterStage eNotify enables online visitors to enter their own
       information requests about specific events on the e-business Web site.
       The CenterStage eNotify system would then deliver notifications of new
       requested information via email or pager update directly to the customer.
       CenterStage eNotify can support thousands of information requests, which
       enables our customers to meet the needs of increasing numbers of users.
       This event-based execution enables customers to receive notifications
       based on timely information.

       An online gift store, for example, can use CenterStage eNotify to invite
       customers to specify the product and price they want, and to then alert
       those customers when the requested item is available.

     - CENTERSTAGE eSYNDICATE -- Our CenterStage eSyndicate product enables
       e-businesses to offer, or publish, select information from their
       e-business portals or e-marketplaces, based on customers' information
       requests, or subscriptions. CenterStage eSyndicate intelligently manages
       and routes the requested information using any electronic format, open
       standard or industry protocol. CenterStage eSyndicate is capable of
       routing a wide range of continuously changing information from an array
       of original sources, including databases and Web pages.

       An automotive manufacturer, for example, may use CenterStage eSyndicate
       to publish parts catalogs to its dealer network. Dealers in the network
       would select the parts information they need and specify how often they
       want the manufacturer to update the information. As the manufacturer adds
       new parts or changes prices on its Web site, CenterStage eSyndicate would
       automatically update dealers on the changes relevant to them.

                                       78

     - XML CONNECT(TM) -- Our XML Connect product is a free, downloadable
       software product that allows e-commerce participants -- including buyers,
       suppliers and e-marketplaces -- to establish secure, reliable, guaranteed
       XML business document exchange, without the need to install and manage
       closed or proprietary XML servers. With XML Connect acting as a
       standardized XML transport, e-commerce participants can achieve secure
       online document exchange quickly and easily.

       A chemical supplies e-marketplace, for example, may use XML Connect to
       quickly establish secure online document exchange with multiple suppliers
       of laboratory equipment. The e-marketplace and each of its suppliers
       would simply download the free XML Connect product, and then use XML
       Connect to select and schedule documents for exchange.

     Using the CenterStage application suite, an e-business portal can rapidly
automate and continuously manage the flow of information among its suppliers,
distributors and customers. In the diagram above, the e-business portal uses
CenterStage eContent to quickly gather and transform diverse product and other
information from a large community of suppliers, regardless of source format. In
addition, the e-business portal uses CenterStage eBizXchange to automate
business transactions with suppliers and also with e-marketplaces and other
affiliates. CenterStage eIntegrate is used to link the e-business portal with
internal systems. The e-business portal may use CenterStage eNotify to
proactively deliver requested notifications to customers, while it uses
CenterStage eSyndicate to publish customized product catalogs and price lists to
affiliates and e-marketplaces.

     An e-marketplace may use the CenterStage product suite to automate and
seamlessly manage the flow of information and transactions among multiple
buyers, suppliers and distributors. The e-marketplace is able to use CenterStage
eContent to capture and transform diverse data from multiple suppliers, while
using CenterStage eBizXchange to handle multiple simultaneous transactions among
buyers, affiliates and suppliers. CenterStage eSyndicate can be used to
proactively publish information of interest to buyers and affiliates using a
variety of formats. Concurrently, participant buyers and suppliers can use
CenterStage eIntegrate to link their e-business operations with their internal
applications.

     Each of the participants in the e-business value chain are able to use our
CenterStage product suite to exchange information and services with other
participants. For example, suppliers may use CenterStage eSyndicate to publish
information to multiple e-marketplaces simultaneously, just as an e-business
portal is able to publish information to its customers. Similarly, corporate
buyers may use CenterStage eIntegrate to link their Web-based procurement
applications to operational systems.

ARCHITECTURE

     Our CenterStage product suite is based on the CenterStage technology
platform. This platform provides a means to develop and execute agents for
accessing, gathering, transforming and distributing information and transactions
using multiple approaches. Our CenterStage technology platform provides easy
application customization capabilities along with a high-performance execution
engine for production environments.

     The CenterStage architecture provides the following environments:

     - rapid development environment -- graphical development environment for
       creating CenterStage agents and for customizing the resulting information
       display; and

     - execution/routing environment -- featuring a high-volume execution server
       for processing information agents.

and the rectangle on the bottom is labeled "Sources."]

     Rapid Development Environment

     At the core of our CenterStage technology platform is a graphical
development environment to create and test information retrieval and
transformation agents. These agents have the ability to access

                                       83
<PAGE>   90

information from multiple sources in many different formats. Some of these
sources include the Web, databases, software applications and various
information systems.

     Flexible Execution/Routing Environment

     Our flexible CenterStage technology architecture can process agents in
three ways:

     - the Agent Engine processes large batches of information on a one-time or
       regularly scheduled basis;

     No customer accounted for more than 10% of our revenues in the year ended
December 31, 1999. For the year ended December 31, 1998, one customer accounted
for 13% of total revenue and a second customer accounted for 11%.

SALES AND MARKETING

     We market our CenterStage products and related services primarily through a
direct sales organization. Our direct sales organization focuses on sales to
recently formed companies that are creating e-business portals and
e-marketplaces and larger corporate customers building or improving their Web
presence. We maintain a sales office in our headquarters in San Ramon,
California and in offices located in the following metropolitan areas: Atlanta,
Boston, Denver, Farmington, Connecticut, Houston, Indianapolis, Kansas City, Los
Angeles, Mt. Laurel, New Jersey, Vienna, Virginia and West Orange, New Jersey.
We intend to increase our North American sales force by opening additional field
sales offices and adding sales representatives to our existing territories.
Additionally, we are expanding our presence in international markets by building
an international sales force.

     Since our inception, we have invested substantial resources in a broad
range of marketing activities to generate demand, gain corporate brand identity,
establish the e-business portal and e-marketplace product category and educate
the market about our products and services. These activities have included
advertising, including both print and online, direct marketing, including direct
mail and e-mail and online seminars, public relations, participating in trade
shows and conferences and providing product information through our Web site.

     In addition to the direct sales channel, we have also entered into several
marketing and referral agreements with industry leading software companies. As
part of these agreements these companies

                                       84
<PAGE>   91

introduce our products and services to prospective customers to generate
qualified sales leads. In some cases we pay a referral fee for these leads.
These fees are based on the net license revenue we receive from these leads and
are included in marketing expense when paid. These agreements enable us to
expand our potential market and help to validate our solution.

     As part of our sales and service offerings, we provide comprehensive
product support through a variety of methods. Our experienced support team
members understand the problems our customers face and work closely with them to
help provide solutions. This comprehensive support enables us to ensure our
customers' satisfaction and increases opportunities for repeat sales and
positive customer references.

COMPETITION

     The market for our products and services is intensely competitive, evolving
and prone to rapid technological change. We expect the intensity of competition
to increase in the future. Competitors vary in size and in the scope and breadth
of the products and services offered. To date, we have faced competition and
sales resistance from the internal information technology departments of current
and potential customers that have developed or may develop in-house systems that
may substitute for those we offer. We expect that internally developed
infrastructure systems will continue to be a principal source of competition for
the foreseeable future. In the business to business integration market, we
encounter competition from webMethods and Vitria Technology, Inc. If we are
successful, we expect to encounter many additional competitors in the future. In
addition, because there are relatively low barriers to entry in the software
market, we expect additional competition from other established and emerging
companies as the Internet software market continues to develop and expand. In
particular, we believe we may face competition from IBM, Microsoft, Oracle and
Sun Microsystems as those companies may perceive entry into our market segment
as strategic. We also may face competition from established companies in the
enterprise application integration and e-business platform markets, any of which
could build and market products that would reduce or eliminate the need for our
technology.

     We believe that the principal competitive factors affecting our market
include core technology, product features, product quality and performance and
customer service. Although we believe that our products and services currently
compete favorably with respect to these factors, our market is relatively new
and is rapidly evolving. We may not be able to maintain our competitive position
against current and potential competitors, especially those with significantly
greater financial, marketing, service, support, technical and other resources.

     Many of our competitors have longer operating histories, significantly
greater financial, technical, marketing and other resources, significantly
greater name recognition and a larger installed base of customers than we have.
In addition, many of our competitors have well-established relationships with
current and potential customers of ours, have extensive knowledge of our
industry and are capable of offering a comparable solution. As a result, our
competitors may be able to respond more quickly to new or emerging technologies
and changes in customer requirements, or to devote greater resources to the
development, promotion and sale of their products and services than we can. In
addition, current and potential competitors have established or may establish
cooperative relationships among themselves or with third parties to increase the
ability of their products and services to address customer needs. Accordingly,
it is possible that new competitors or alliances among competitors may emerge
and rapidly acquire significant market share. We also expect that competition
will increase as a result of software industry consolidations.

     Increased competition is likely to result in price reductions, reduced
gross margins and loss of market share, any of which could seriously harm our
business, operating results and financial condition. We may not be able to
compete successfully against current and future competitors.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

     Our success and ability to compete are substantially dependent on our
internally developed technologies and trademarks, which we seek to protect
through a combination of copyright, trade secret

                                       85
<PAGE>   92

and trademark law. We also enter into confidentiality or license agreements with
our employees and consultants, and other companies with whom we have concluded
marketing agreements and generally seek to control access to and distribution of
our documentation and other proprietary information. Despite these precautions,
it may be possible for a third party to copy or otherwise obtain and use our
proprietary information without authorization or to develop similar technology
independently. We pursue the registration of our trade and service marks in the
United States and internationally, and we have registered the trademarks
OnDisplay and CenterStage in the United States. Effective trademark, service
mark, copyright and trade secret protection may not be available in every
country in which our services are distributed or made available through the
Internet, and policing unauthorized use of our proprietary information is
difficult.

     Legal standards relating to the validity, enforceability and scope of
protection of certain proprietary rights in Internet-related businesses are
uncertain and still evolving. We cannot give any assurance as to the future
viability or value of any of our proprietary rights. In addition, we cannot give
any assurance that the steps taken by us will prevent misappropriation or
infringement of our proprietary information. Any intellectual property
infringement or misappropriation, should it occur, could have a material adverse
effect on our business, operating results and financial condition.

     In addition, litigation may be necessary in the future to enforce our
intellectual property rights, to protect our trade secrets or to determine the
validity and scope of the proprietary rights of others. Any intellectual
property litigation would result in substantial costs and diversion of resources
and management attention and could have a material adverse effect on our
business, operating results and financial condition. Our business activities may
infringe upon the proprietary rights of others, and other parties may assert
infringement claims against us. Any claim and resultant litigation, should it
occur, might subject us to significant liability for damages and might result in
invalidation of our proprietary rights and even if not meritorious, would be
time consuming and expensive to defend and would result in the diversion of
management time and attention, any of which might have a material adverse effect
on our business, operating results and financial condition.

EMPLOYEES

     As of December 31, 1999, we employed 175 persons. Our success will depend
in large part upon our ability to attract and retain employees. We face
competition in this regard from other companies, but we believe that we maintain
good relations with our employees.

FACILITIES

     We sublease approximately 38,000 square feet of office space in two office
locations in San Ramon, California and smaller sales offices located in the
following metropolitan areas: Atlanta, Boston, Denver, Farmington, Connecticut,
Houston, Indianapolis, Kansas City, Missouri, Los Angeles, Mt. Laurel and West
Orange, New Jersey and Vienna, Virginia. We believe that our San Ramon
facilities will meet our space requirements for the next year. The sublease for
the San Ramon facilities expire in July 2000 and July 2002 with no option to
extend.

LEGAL PROCEEDINGS

     We are not a party to any material legal proceeding.

                 ONDISPLAY MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements based upon current
expectations that involve risks and uncertainties. When used in this prospectus,
the words "intend," "anticipate," "believe," "estimate," "plan" and "expect" and
similar expressions as they relate to OnDisplay are included to identify
forward-looking statements. The following discussion should be read in
conjunction with the Financial Statements and Notes included elsewhere in this
prospectus. Our actual results and the timing of certain events could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including those set forth under "Risk Factors" and
elsewhere in this prospectus.

OVERVIEW

     We expect that the significant majority of our revenues will continue to be
derived from our CenterStage product suite and related services for the
foreseeable future. Our revenues, which consist of software license revenues and
service revenues, totaled $265,000, $3.3 million and $11.1 million for the years
ended December 31, 1997, 1998, and 1999. Substantially all of our revenues since
inception have been derived from the license of applications based on our
CenterStage technology platform and related services. Our product pricing is
principally based on the number of servers running the software and the number
of different information sources accessed by each customer. Service revenues
consist of fees received for consulting, maintenance, customer support and
training.

     We sell our CenterStage products and related services primarily through a
direct sales force based in the United States. In addition, we have entered into
co-marketing arrangements to enhance our indirect sales channels. In the future,
we expect that the majority of our revenues will continue to be derived from our
direct sales force.

     Revenues from software license agreements are recognized upon shipment or
upon notification to the customer of the downloadable software location,
provided that a signed contract exists, the fee is fixed and determinable, and
collection of the resulting receivable is probable and, if applicable,
acceptance criteria are met. Service revenues are recognized as services are
performed or, with respect to maintenance, ratably over the contract term,
typically over one year.

     Our cost of revenues includes costs associated with the electronic
transmission of software and royalties for third party embedded software, which
are not material, salaries and related expenses for our consulting and training
services and customer support organizations, cost of third parties contracted to
provide consulting services to customers and an allocation of our facilities and
depreciation expenses.

     We allocate the total costs for facilities to each functional area that
uses the overhead and facilities services based on their headcount. These
allocated charges include facility rent for the corporate office, communication
charges, and depreciation expense for office furniture and equipment.

     Since inception, we have incurred substantial research and development
costs and invested heavily in the expansion of our sales, marketing and
professional services organizations to support our long-term growth strategy.
The number of our full-time employees increased from 39 as of December 31, 1997,
to 65 as of December 31, 1998, and to 175 as of December 31, 1999. As a result
of these expenses, we have incurred net losses in each fiscal quarter since
inception and, as of December 31, 1999, had an accumulated deficit of $31.2
million. We intend to continue expanding our sales and marketing groups and to
implement significant marketing programs to solidify our market position, gain
name recognition, establish an international presence and introduce new products
and services. We also intend to increase our research and development and
professional services groups so that we can continue investing in new products
and adding additional services to benefit our customers. As a result of these
anticipated expenditures we expect to incur net losses in the foreseeable
future.

     Through December 31, 1999, we have recorded aggregate deferred stock-based
compensation of $33.5 million in connection with stock option grants. This
compensation will be amortized over the four-
                                       87
<PAGE>   94

year vesting period of the options. Included in our expenses will be stock-based
compensation as a result of stock options granted through December 31, 1999, of
$15.4 million in 2000, $8.0 million in 2001, $4.2 million in 2002 and $1.6
million in 2003.

     We believe that period-to-period comparisons of our operating results
should not be relied upon as indicative of future performance. Our prospects
must be considered in light of the risks, expenses and difficulties frequently
encountered by companies in early stages of development, particularly companies
in new and rapidly evolving markets. There can be no assurance we will be
successful in addressing such risks and difficulties. Although we have
experienced revenue growth recently, this growth may not continue. In addition,
we may not achieve or maintain profitability in the future.

</TABLE>

YEARS ENDED DECEMBER 31, 1998 AND 1999

  Revenues

     Our revenues are derived from software licenses and related services. Our
revenues were $3.3 million and $11.1 million for the years ended December 31,
1998 and 1999. In 1998 two customers accounted for more than 10.0% of our total
revenues. In 1999 no customer accounted for more than 10.0% of our total
revenues.

     License Revenues. Our license revenues were $2.2 million and $6.8 million
for 1998 and 1999, and represented 66.7% and 61.6% of total revenues. This
dollar increase reflected initial market acceptance of our CenterStage products
in the e-commerce markets in 1999, and an increase in the size and productivity
of the sales force. During 1998, license revenues were derived primarily from
enterprise resource planning markets.

     Service Revenues. Our service revenues were $1.1 million and $4.3 million
for 1998 and 1999, and represented 33.3% and 38.4% of total revenues. The
increase in 1999 service revenues, compared to the 1998 service revenues, was
primarily due to the increase in our customer base and service contracts
performed during this period. We expect that the proportion of our service
revenues to total revenues will fluctuate in the future, depending in part on
our customers' breadth and scope of implementation and the mix of products
implemented.

                                       88
<PAGE>   95

  Cost of Revenues

     Our cost of revenues was $1.6 million, representing 48.5% of revenues, and
$4.3 million, representing 38.4% of revenues, for 1998 and 1999. This dollar
increase was primarily due to an increase in professional service support
personnel to manage and support our growing customer base. Cost of service
revenues, which constitutes substantially all of cost of revenues, has exceeded
service revenues primarily due to our investment in our consulting and training
services and customer support organizations. Cost of revenues as a percentage of
revenues may vary between periods due to the mix of services we provide and the
extent to which we utilize outside subcontractors to perform our service work.

  Operating Expenses

     Sales and Marketing. Our sales and marketing expenses increased 107.4% from
$5.7 million, representing 171.9% of revenues, in 1998 to $11.9 million,
representing 107.4% of revenues, in 1999. This dollar increase was primarily due
to an increase of approximately $3.7 million in compensation and recruiting
expenses, resulting principally from increased staffing and higher sales
commissions related to the period to period increase in revenues, and increased
spending of $1.5 million on marketing programs. We believe sales and marketing
will increase substantially in future periods as we continue to expand our sales
force, establish our international presence and expand our marketing programs.

     Research and Development. Our research and development expenses increased
78.8% from $2.6 million, representing 78.9% of revenues, in 1998 to $4.7
million, representing 42.5% of revenues, in 1999. This dollar increase was
primarily due to an increased personnel costs of approximately $900,000 as well
as increased costs related to contract development personnel of approximately
$823,000. We believe that research and development expenditures will increase
substantially in future periods as we continue to develop additional products
and enhance existing products. Technological feasibility of our software is
generally not established until substantially all product development is
complete. Historically, software development costs eligible for capitalization
have been insignificant, and all costs related to research and development have
been expensed as incurred.

     General and Administrative. Our general and administrative expenses
increased 184.6% from $1.2 million, representing 35.9% of revenues in 1998, to
$3.4 million, representing 30.8% of revenues, in 1999. This dollar increase was
primarily due to increased personnel costs of approximately $777,000, facilities
expansion costs of approximately $446,000, professional and outside service fees
of approximately $586,000, and other costs related to supporting the expansion
of our business. We believe that general and administrative costs will increase
in future periods as we incur additional costs related to the overall growth of
our company.

     Amortization of Deferred Stock-Based Compensation. During 1998 and 1999, we
recorded deferred compensation of $2.2 million and $31.3 million in connection
with stock option grants. We are amortizing this amount over the vesting periods
of the applicable options, resulting in amortization expense of $618,000 and
$3.7 million for 1998 and 1999.

     Loss From Operations. For 1999 we had an operating loss of $16.9 million
compared to an operating loss of $8.5 million for 1998. The increase in our
operating loss from the prior year period was the result of our operating
expenses increasing $13.5 million, the largest components of which were the $6.2
million increase in sales and marketing expenses and the $3.1 million increase
in amortization of stock-based compensation, while gross profit increased $5.1
million.

     Interest Income and Other. Our Interest income and other was $174,000 and
$532,000 for 1998 and 1999. The increase in interest income was primarily the
result of higher average cash balances available for investment.

     Interest Expense. Our interest expense was $43,000 and $394,000 for 1998
and 1999. Increased interest expense resulted from additional borrowings and
higher capital lease obligations during 1999; including the expense related to
the valuation of warrants granted to a lender as part of these borrowings.

<PAGE>   96

YEARS ENDED DECEMBER 31, 1997 AND 1998

  Revenues

     Our revenues were $265,000 and $3.3 million for 1997 and 1998. In 1997,
three customers accounted for more than 10.0% of total revenues, and in 1998 two
customers accounted for more than 10.0% of our total revenues.

     License Revenues. Our license revenues were $265,000 and $2.2 million in
1997 and 1998. This increase in license revenues was attributable to an increase
in sales to new customers resulting from increased headcount in our sales force.

     Service Revenues. Our service revenues were $1.1 million in 1998, which was
the first year we offered consulting, implementation, maintenance, training and
customer support services. We began recognition of revenues from maintenance
contracts in 1998. Service revenues represented 33.3% of our total revenues in
1998.

  Cost of Revenues

     Our cost of revenues was $1.6 million in 1998, which was the first year we
offered consulting, implementation, maintenance, training and customer support
services. In 1998 we established our consulting and customer support
organization, which required hiring and training of personnel prior to selling
and recognizing revenues for such services.

  Operating Expenses

     Sales and Marketing. Our sales and marketing expenses were $2.8 million and
$5.7 million, in 1997 and 1998. This increase was primarily due to our
investment in our sales and marketing infrastructure, which included significant
personnel-related expenses such as salaries, benefits and commissions,
recruiting fees, and related costs of hiring sales management, sales
representatives, sales engineers and marketing personnel. Personnel-related
expenses increased approximately $2.0 million in 1998.

     Research and Development. Our research and development expenses were $2.0
million and $2.6 million, in 1997 and 1998. These increases were primarily due
to the increase in the number of software developers, quality assurance
personnel and outside contractors to support our product development and testing
activities related to the development and release of our CenterStage suite of
products. Personnel-related expenses increased approximately $644,000 in 1998.

     General and Administrative. Our general and administrative expenses were
$1.2 million in both 1997 and 1998. These expenses remained flat from 1997 to
1998, as we directed our resources toward growing our sales and marketing and
our research and development organizations, rather than expanding our general
and administrative organization.

     Amortization of Deferred Stock-Based Compensation. During 1998 we recorded
deferred compensation of $2.2 million in connection with stock option grants. We
are amortizing this amount over the vesting periods of the applicable options,
resulting in amortization expenses of $618,000 in 1998.

     Loss From Operations. Our operating losses were $5.7 million and $8.5
million for 1997 and 1998. The year to year increase in our operating loss from
the prior year period was the result of our operating expenses increasing at a
rate higher than our revenues and gross profit.

     Interest Income and Other. Our interest income and other were $173,000 and
$174,000 in 1997 and 1998. Interest income and other was earned from the
investment of cash generated from the proceeds of preferred stock sales.

     Interest Expense. Our interest expense was $18,000 and $43,000 in 1997 and
1998. Interest expense resulted from a financing agreement established in June
1997 to purchase equipment.

QUARTERLY RESULTS OF OPERATIONS

     The following table sets forth unaudited statement of operations data for
the eight quarters in the two year period ended December 31, 1999 and data
expressed as a percentage of our total revenues for the periods indicated. This
data has been derived from our unaudited financial statements that have been
prepared on the same basis as the audited financial statements and, in the
opinion of our management, include all adjustments, consisting of normal
recurring adjustments, necessary for a fair presentation of the information when
read in conjunction with the financial statements and Notes. Our quarterly
results have been in the past and may in the future be susceptible to
significant fluctuations. As a result, we believe that results of operations for
interim periods should not be relied upon as any indication of the results to be
expected in any future period.

     Our quarterly operating results have fluctuated significantly in the past,
and will continue to fluctuate in the future, as a result of a number of
factors, many of which are outside our control. These factors include:

     - demand for and timing of the sales of our CenterStage products and
       related services;

     - actions taken by our competitors, including new product introductions and
       enhancements;

     - changes in the rapidly evolving market for e-business infrastructure
       applications;

     - our ability to develop, introduce and market e-business infrastructure
       applications and enhancements to our existing CenterStage products on a
       timely basis;

     - changes in our pricing policies and those of our competitors; and

     - our inability to complete large sales on schedule.

     We have experienced delays in the planned release dates of our new software
products or upgrades in the past, and have discovered software defects in our
new products after their introduction. Our new products or upgrades may not be
released according to schedule, or when released may contain defects. Either of
these situations could result in adverse publicity, loss of revenues, delay in
market acceptance and claims by customers brought against us, any of which could
harm our business. In addition, the timing of individual sales has been
difficult for us to predict, and large individual sales have, in some cases,
occurred in quarters subsequent to those anticipated by us. The loss or deferral
of one or more significant sales may harm our quarterly operating results.

     We expect that, based on seasonal factors that typically affect companies
in the software industry, our license revenues in the first quarter may in the
future tend to be lower than those in the fourth quarter.

LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 1999 we had cash and equivalents of $109.6 million,
compared to $4.6 million at December 31, 1998, an increase of $105 million.

     In December 1999, we completed our initial public offering of 3,500,000
shares of common stock and, concurrently, completed a private offering of
300,000 shares of common stock, generating total net proceeds of $97.6 million.
During 1999 we generated an additional $16.4 million from the sale of preferred
stock. We also raised $3.0 million from the issuance of long-term debt, and had
financed equipment purchases totaling approximately $729,000.

     During 1999 $11.2 million in cash was used in operating activities
primarily to fund ongoing operations.

     In 1999, our investing activities consisted of purchases of property and
equipment. Capital expenditures, including those under capital leases, totaled
$1.4 million.

     We expect to experience significant growth in our operating expenses in the
future, particularly in sales and marketing and research and development in
order to execute our business plan. As a result, we anticipate that these
operating expenses, as well as planned capital expenditures, will constitute a
material use of our cash resources. In addition, we may utilize cash resources
to fund acquisitions or investments in complementary businesses, technologies or
product lines. We believe that we have working capital sufficient to meet our
operational and capital expenditure requirements for at least the next twelve
months. Thereafter, we may find it necessary to obtain additional equity or debt
financing. In the event additional financing is required, we may not be able to
raise it on acceptable terms or at all.

YEAR 2000 COMPLIANCE

  Background of Year 2000 Issues

     Many currently installed computer systems and software products are unable
to distinguish between twentieth century dates and twenty-first century dates
because these systems were developed using two digits rather than four to
determine the applicable year. For example, computer programs that have
date-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This error could result in system failures or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities. As a result, many companies' software and
computer systems may need to be upgraded or replaced to comply with year 2000
requirements.

  State of Readiness

     Our business is dependent on the operation of numerous systems that could
potentially be affected by year 2000 related problems. Those systems include,
among others:

     - software products sold to customers;

     - hardware and software systems used by us to deliver products and services
       to customers, including our proprietary software systems as well as
       software supplied by third parties;

     - communications networks such as the Internet and private Intranets;

     - the internal systems of our customers and suppliers;

     - the hardware and software systems used internally by us in the management
       of our business; and

     - non-information technology systems and services, such as power, telephone
       systems and building systems.

     We have tested our software products and have determined that current
versions of all of our software products are year 2000 compliant by ensuring our
products support the use, output, storage, entry and creation of all dates
before, on, and after January 1, 2000. However, we cannot assure you that all
other hardware and software products used by our customers in conjunction with
our products can properly exchange accurate date data.

     We have established a year 2000 compliance team, composed of high-level
representatives of the product, information systems and general administrative
departments to evaluate our internal and external systems. The team was charged
with the responsibility of formulating and implementing our year 2000 readiness
and applied a phased approach to analyzing our operations and relationships as
they relate to the year 2000 problem. The phases of our year 2000 program were
as follows:

     Phase 1:  establishment of a year 2000 team;

     Phase 2:  assignment of responsibility for external issues, such as
               products licensed by us, internal issues, such as systems,
               facilities, equipment, software and legal audit;

     Phase 3:  inventory of all aspects of our operations and relationships
               susceptible to the year 2000 problem; and

     Phase 4:  remediation and testing.

     We have completed all of the phases of our program and have not experienced
any year 2000 issues.

  Cost of Product and Internal Systems Preparation

     To date, the total cost of year 2000 preparation and remediation have not
been material.

  Risks Related to Year 2000 Issues

     Based on our assessment to date, we believe the current versions of our
software products are year 2000 compliant. However, our products are generally
integrated into enterprise and other systems involving sophisticated hardware
and complex software products which may not be year 2000 compliant. In addition,
in some cases, some earlier year 2000 compliant versions of our software, while
compatible with earlier, non-year 2000 compliant versions of other software
products with which our software is integrated, are not compatible with some
more recent year 2000 compliant versions of other software providers. While we
do not believe we have any obligation under these circumstances given that these
customers are using our older versions of our software products, there can be no
assurance that we will not be susceptible to claims or complaints by our
customers. Our year 2000 compliance efforts may depend on our customers' ability
to manage their own year 2000 issues. We sell our products to companies in a
variety of industries, each of which is experiencing different year 2000
compliance issues. Customer difficulties with year 2000 issues might require us
to devote additional resources to resolve underlying problems.

     Although we have not been a party to any litigation or arbitration
proceeding related to year 2000 compliance issues to date involving our products
or services, there can be no assurance that we will not be required to defend
our products or services in such proceedings, or to negotiate resolutions of
claims based on year 2000 issues. The costs of defending and resolving year 2000
related disputes, regardless of the merits of such disputes, and any liability
for year 2000 related damages, including consequential damages, could have a
material adverse effect on our business, operating results and financial
condition.

     Purchases of our products by customers and potential customers may be
affected by year 2000 issues as companies expend significant resources to
correct or upgrade their current software systems for year 2000 compliance or to
deal with the consequences of any failures to achieve year 2000 compliance. To
the extent year 2000 issues cause significant delay in, or cancellation of,
decisions to purchase our products or services, our business would be adversely
affected.

     To date, we have not encountered any material year 2000 problems with our
internal computer systems or any other equipment that might be susceptible to
such problems. Our plan for the year 2000 called for compliance verification of
external vendors supplying software and information systems to us and
communication with significant suppliers to determine the readiness of third
parties' remediation of their own year 2000 issues. To date we have found none
of our suppliers to be year 2000 noncompliant. In the event that any such third
parties' products, services or systems do not meet year 2000 requirements on a
timely basis, we could experience substantial disruptions to our business. We
could also experience adverse effects on our business if we fail to identify all
year 2000 dependencies in our systems and in the systems of our suppliers,
customers and financial institutions. We may not identify and remediate all
significant year 2000 problems on a timely basis, remediation efforts may
involve significant time and expense, and unremediated problems may cause major
disruptions to our continuing operations and may lead to delays, lost sales and
material losses.

     We are unable to determine at this time whether these or other year 2000
failures will occur and will have a material impact on our business, results of
operations, or financial condition. This inability is particularly due to the
potential scope of the year 2000 problem and our inability to assure the year
2000 compliance of customers or to confirm the assurances received from vendors
and service providers such as utilities. Although we have considered our
possible responses to some year 2000 contingencies, we have not developed and
have no current effort underway to develop a contingency plan to attempt to deal
with the complex and extreme circumstances that could accompany a likely worst
case scenario involving year 2000 related failures in our internal systems, our
supply channels, our customers' businesses and the general business
infrastructure.

OPTION GRANTS IN LAST FISCAL YEAR

     The following table provides information relating to stock options granted
to each of OnDisplay's named executive officers during the fiscal year ended
December 31, 1999. All of these options were granted under our 1996 stock plan
and have a term of 10 years, subject to earlier termination in the event the
optionee's services terminate. The options vest over a four year period from the
date of grant but are exercisable at any time for all the option shares. If the
optionee exercises an option to purchase shares that are unvested and the
optionee's services to OnDisplay terminate before all the shares have vested, we
have the right to repurchase the then unvested shares at the original exercise
price. The exercise prices of the options are equal to the fair market value of
our common stock on the date of grant, as determined by our board of directors.

     The potential realizable value in the table is calculated by assuming that
the price of our common stock increases from $28.00 per share at assumed
appreciation rates of 5% and 10%, compounded annually over the 10-year term of
the option, and subtracting from that result the total option exercise price.
These assumed appreciation rates comply with the rules of the Securities and
Exchange Commission and do not represent our prediction of the performance of
our stock price. The base of $28.00 per share was the initial offering price of
the OnDisplay common stock in our public offering on December 17, 1999.

AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND VALUES OF UNVESTED OPTIONS AT
FISCAL YEAR END

     The following table sets forth for each of OnDisplay's named executive
officers information relating to option exercises during the fiscal year ended
December 31, 1999 and the number and value of securities underlying vested and
unvested options they held at December 31, 1999. As discussed in the text above
the preceding table, all options are fully exercisable from the date of grant,
but the underlying shares vest over a four year period. The "Value Realized for
Exercised Options" is based on $28.00 per share, the initial offering price of
our public offering on December 17, 1999. The "Value of Unexercised In-the-Money
Options" at December 31, 1999 is based on $90.875 per share, the closing price
on December 31, 1999. In each case, the per share exercise price is subtracted
and the resulting amount is multiplied by the applicable number of shares.

  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF ONDISPLAY

     The following table sets forth information regarding the beneficial
ownership of OnDisplay common stock as of December 31, 1999, by the following
individuals or groups:

     - each person, or group of affiliated persons, whom we know beneficially
       owns more than 5% of our outstanding stock;

     - each of our Named Executive Officers;

     - each of our directors; and

     - all of our directors and executive officers as a group.

     Unless otherwise indicated, the address for each stockholder in this table
is c/o OnDisplay, Inc., 12667 Alcosta Boulevard, Suite 300, San Ramon, CA 94583.
Except as otherwise noted, and dependent on applicable community property laws,
to the best of our knowledge, the persons named in this table have sole voting
and investing power with respect to all of the shares of common stock held by
them.

     This table sets forth percentage ownership based on 20,175,507 shares of
common stock outstanding as of February 15, 2000 as adjusted to reflect the
1,938,971 shares of common stock which would be issued in the merger if such
merger had been completed as of February 15, 2000. Options to purchase shares of
our common stock that are exercisable within 60 days of February 28, 2000 are
deemed to be beneficially owned by the persons holding these options for the
purpose of computing percentage ownership of that person, but are not treated as
outstanding for the purpose of computing any other person's ownership
percentage. Options held by the persons in the table are fully exercisable and
are therefore included in the table because the underlying shares are deemed to
be beneficially owned. However, some of the underlying shares, as well as some
shares that are held by such persons as a result of option exercises, are not
fully vested. See "OnDisplay Management -- Option Grants in Last Fiscal Year."

                      CERTAIN INFORMATION REGARDING OBERON

                             DESCRIPTION OF OBERON

BUSINESS

     Oberon is a leading developer of software solutions designed to automate
the integration required to enable a business's effective transition to an
e-business platform. Oberon's solutions enable the connection of customers and
suppliers, the automation of internal business processes required to work
effectively with customers and suppliers, and the ability to rapidly respond to
changes in these relationships. This is accomplished through Oberon's
e-Enterprise suite of integration products, a visual integration development
environment and suite of intelligent applications and technology adapters that
together simplify the integration of business applications, also known as Oberon
Building Blocks, and a growing network of third-party and service partners.
Oberon's products and services are designed to support each stage of e-business
integration including intra-enterprise, business-to-business,
business-to-consumer and e-marketplace.

     Oberon first shipped Oberon Prospero, now enhanced and reengineered for
e-business and renamed Oberon e-Enterprise, in November 1999. E-business is the
single largest factor influencing change in today's business community. It
continues to take hold in both traditional organizations and the expanding
number of Internet related companies. E-business will affect how every large
organization does business and will enable the creation of many new forms of
business. Oberon believes that a basic premise of enabling e-business is an
effective integration strategy. A strategy that leverages the high quality
information found in enterprise systems, and in the systems of outside services
and suppliers, and connects such information to the many systems that link to
the extended enterprise. Oberon's Oberon e-Enterprise product family fulfills
that premise by providing a continuous optimization of multi-company business
processes through a secure Internet-based platform architecture that integrates
suppliers, customers, and partners.

     A key strength of Oberon e-Enterprise is its visual integration environment
which allows customers to achieve the integration they desire using a unique
object-oriented approach and to develop a visual plan for integrating enterprise
systems. Using Oberon e-Enterprise Oberon's customers mix, match, and manipulate
Oberon Building Blocks, connecting them together and designing the business
processes which become the customer's integration solution. Oberon Building
Blocks are pre-packaged, intelligent components that automate function
integration that would otherwise require custom written interface codes. Oberon
Building Blocks completely remove the complexity of implementing business-level
processes that span enterprise applications, infrastructure, businesses, and
e-commerce systems.

     Currently, Oberon directly markets its products in North America and Europe
and has established distribution agreements in South America and Japan. Oberon
has OEM relationships on a worldwide basis with leading application and
technology vendors. As of December 31, 1999, Oberon's field operations
organization consisted of 16 sales executives and sales engineers.

     As of December 31, 1999, Oberon had a total of 91 employees: 39 in
engineering, 27 in sales and marketing, 16 in consulting services and customer
support, and 7 in finance and administration. From time to time Oberon also
employs independent contractors.

     Oberon was incorporated in Massachusetts in October 1989. Its executive
offices are located at 215 First Street, Cambridge, Massachusetts 02142. Its
telephone number is (617) 494-0990, and its Internet web site is located at
http://www.oberon.com, "Oberon Software Incorporated", "Oberon e-Enterprise" and
"Oberon Prospero" are all trademarks owned by Oberon.

               OBERON'S MANAGEMENT'S DISCUSSIONS AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

     Oberon has experienced substantial losses since its inception, and as of
December 31, 1999, it had an accumulated deficit of $36.8 million. These net
losses and accumulated deficit resulted from Oberon's lack of substantial
revenue and the significant costs incurred in the development of its products
and the establishment of its sales and marketing organization. Oberon expects to
increase its expenditures in all areas in order to execute its business plan,
particularly in sales and marketing and customer support. The planned increases
in sales and marketing will primarily result from the hiring of additional
business development personnel, expansion of direct sales into Europe and
expansion of marketing programs to increase awareness of Oberon. The planned
increase in customer support will be a combination of additional support
personnel and increasing the staffing in the professional service organization
to support its customers. Oberon will also continue to increase investments in
research and development.

     Although Oberon has experienced revenue growth in recent periods, there can
be no assurance that such growth rates are sustainable, and therefore such
growth rates should not be considered indicative of future operating results.
There can also be no assurance that Oberon will be able to continue to increase
its revenue or attain profitability or, if increases in revenue and
profitability are achieved, that they can be sustained. Oberon believes that
period-to-period comparisons of its historical operating results are not
meaningful and should not be relied upon as an indication of future performance.

RESULTS OF OPERATIONS

  COMPARISON OF RESULTS FOR THE THREE MONTHS ENDED DECEMBER 31, 1999 AND 1998

     Revenue

     Total revenue increased to $1.5 million for the three month period ended
December 31, 1999 from $796,000 for the three month period ended December 31,
1998.

     Software Licenses. Software license revenue decreased to $487,000 for the
three month period ended December 31, 1999 from $523,000 for the three month
period ended December 31, 1998. Software license revenue was below Oberon's
expectations as a number of potential customers delayed their purchase
decisions.

     Services Revenue. Services revenue increased to $691,000 for the three
month period ended December 31, 1999 from $274,000 for the three month period
ended December 31, 1998. This increase was primarily attributable to increasing
Oberon's consulting service capacity.

     Royalties Revenue. Royalties revenue was $295,000 in the three month period
ended December 31, 1999 versus zero in the three month period ended December 31,
1998. The increase in royalties revenue can be attributed to the commencement of
shipping of Oberon's software by its licensees as part of their integrated
solution.

     Cost of Revenue

     Cost of Software. Cost of software increased to $103,000, or 13.1% of
software and royalties revenue, for the three month period ended December 31,
1999 from $21,000, or 3.9% of software license and royalties revenue, for the
three month period ended December 31, 1998. This increase was primarily
attributable to incorporating more third party software into Oberon's products.
Oberon anticipates that the cost of software as a percentage of software license
and royalties revenue, primarily royalty obligations to third parties whose
products are incorporated into Oberon's products, will decrease as these
revenues increases.

     Cost of Services Revenue. Cost of services revenue increased to $581,000,
or 84.1% of services revenue, for the three month period ended December 31, 1999
from $272,000, or 99.4% of services

                                       105
<PAGE>   112

revenue, for the three month period ended December 31, 1998. The increase in the
cost of services was primarily attributed to increased staffing as the number of
service employees increased to 16 as of December 31, 1999 from 8 as of December
31, 1998.

     Operating Expenses

     Research and Development. Research and development expenses consist
primarily of personnel and related costs associated with developing its family
of software products. Research and development expenses increased to $1.2
million, or 83.7% of total revenue, for the three month period ended December
31, 1999 from $726,000, or 91.2% of total revenue, for the three month period
ended December 31, 1998. The increase primarily resulted from costs associated
with an increase in the number of research and development employees to 39 as of
December 31, 1999 from 26 as of December 31, 1998. Oberon anticipates that
research and development expenses will continue to increase in absolute dollars
but at a lower rate than revenue growth.

     Sales and Marketing. Sales and marketing expenses consist primarily of
compensation costs for sales and marketing personnel, including sales
commissions, travel expenses, trade shows, and other costs related to product
promotion and marketing programs. Sales and marketing expenses increased to $1.5
million, or 103.0% of total revenue, for the three month period ended December
31, 1999 from $922,000, or 115.8% of total revenue, for the three month period
ended December 31, 1998. The increase was primarily due to increasing the size
of the direct sales and business development organizations. Total sales and
marketing personnel increased to 29 as of December 31, 1999 from 17 as of
December 31, 1998. In addition, the increase in total sales and marketing
expense was attributable to costs associated with an increase in public
relations and marketing programs. Sales and marketing expenses are anticipated
to continue to increase with the expansion into international markets and higher
marketing expenditures to increase the awareness of Oberon.

     General and Administrative. General and administrative expenses consist
primarily of compensation costs for finance, administration and executive
management. General and administrative expenses decreased to $229,000, or 15.6%
of total revenue, for the three month period ended December 31, 1999 from
$279,000, or 35.0% of total revenue, for the three month period ended December
31, 1998.

     Other Income (Expense). Interest income increased to $79,000, or 5.4% of
total revenue, for the three month period ended December 31, 1999 from $54,000,
or 6.7% of total revenue for the three month period ended December 31, 1998. The
increase was due to higher average cash balances. Interest expense increased to
$80,000, or 5.4% of total revenue, for the three month period ended December 31,
1999 from $5,700, or 0.7% of total revenue, for the three month period ended
December 31, 1998. The increase in interest expense was the result of Oberon's
borrowing $4 million from Comdisco Ventures as of September 30, 1999. Other
expense increased to $15,000 or 1.0% of total revenue, for the three month
period ended December 31, 1999 from $1,000, or 0.1% of total revenue, for the
three month period ended December 31, 1998.

  COMPARISON OF RESULTS FOR THE YEARS ENDED SEPTEMBER 30, 1999 AND 1998

     Revenue

     Total revenue, consisting of software license, services revenue and
royalties, increased to $4.7 million for the year ended September 30, 1999 from
$2.0 million for the year ended September 30, 1998.

     Software Licenses. Software licenses revenue increased to $2.8 million for
the year ended September 30, 1999 from $1.4 million for the year ended September
30, 1998. Oberon's Prospero 2.0 product was released for sale in March 1998 and
was well received in the enterprise application integration, market place.

     Services Revenue. Services revenue increased to $1.4 million for the year
ended September 30, 1999 from $396,000 for the year ended September 30, 1998.
This increase was primarily attributable to

                                       106
<PAGE>   113

implementation services for the new sales of Prospero 2.0 and to a lesser extent
the increase in software maintenance contracts associated with the increase in
license sales in 1999.

     Royalties Revenue. Royalties revenue increased to $444,000 for the year
ended September 30, 1999 from $216,000 for the year ended September 30, 1998.
The increase in royalties revenue can be primarily attributed to the
commencement of shipping Oberon's software by its licensees as part of their
integrated solution.

     Cost of Revenue

     Cost of Software. Cost of software and royalty revenue increased to
$139,000, or 4.2% of software license and royalties revenue, for the year ended
September 30, 1999 from $100,000, or 6.4% of software license and royalties
revenue, for the year ended September 30, 1998. The major cost component consist
of royalty paid to third party software companies for the right to incorporate
their product in Oberon's software.

     Cost of Services Revenue. Cost of services revenue increased to $1.4
million, or 104% of services revenue, for the year ended September 30, 1999 from
$403,000, or 102% of services revenue, for the year ended September 30, 1998.
The increase in the cost of services was primarily attributable to an increase
in personnel as the number of service employees increased to 13 as of September
30, 1999 from 7 as of September 30, 1998.

     Operating Expenses

     Research and Development. Research and development expenses increased to
$3.7 million, or 79.1% of total revenue for the year ended September 30, 1999
from $2.4 million, or 120.7% of total revenue, for the year ended September 30,
1998. The increase primarily resulted from costs associated with an increase in
the number of research and development employees to 40 as of September 30, 1999
from 26 as of September 30, 1998.

     Sales and Marketing. Sales and marketing expenses increased to $4.9
million, or 106.1% of total revenue, for the year ended September 30, 1999 from
$2.9 million, or 145.7% of total revenue, for the year ended September 30, 1998.
The increase was primarily due to:

     - costs associated with increasing the size of direct sales organization;

     - investments in a business development organization to sign up software
       companies to incorporate the Oberon software into their integration
       solution; and

     - higher costs associated with a substantial marketing effort to increase
       market awareness of Oberon and its products.

     General and Administrative. General and administrative expenses consist
primarily of compensation costs for finance, administration and executive
management, legal and audit. General and administrative expenses decreased to $1
million, or 21.6% of total revenue, for the year ended September 30, 1999 from
$1.3 million, or 66% of total revenue, for the year ended September 30, 1998.
The decrease primarily resulted from a reduction in legal expenses.

     Other Income (Expense). Interest income increased to $321,000, or 6.9% of
total revenue, for the year ended September 30, 1999 from $209,000, or 10.6% of
total revenue, for the year ended September 30, 1998 as a result of higher
average cash balances during 1999. Interest expense decreased to $32,000 or 0.7%
of total revenue, for the year ended September 30, 1999 from $126,000, or 6.4%
of total revenue, for the year ended September 30, 1998. The decrease in
interest expense was the result of less debt financing as a result of the
recapitalization of the company in February 1998. Other expense increased to
$56,000 or 1.2% of total revenue, for the year ended September 30, 1999 from
$8,000, or 0.4% of total revenue, for the year ended September 30, 1998.

  COMPARISON OF RESULTS FOR THE YEARS ENDED SEPTEMBER 30, 1998 AND 1997

     Revenue

     Total revenue increased to $2.0 million for the year ended September 30,
1998 from $727,000 for the year ended September 30, 1997. The increase was due
to refocusing Oberon's activities from providing developer licenses, as well as
to providing broader applications for the enterprise application integration
market place. The average sales price is significantly higher in the enterprise
application integration market versus the developer market.

     Cost of Revenue

     Cost of Software. Cost of software and royalty revenue decreased to
$100,000, or 6.4% of software license and royalties revenue, for the year ended
September 30, 1998 from $110,000, or 19.7% of software license and royalties
revenue, for the year ended September 30, 1997. The major cost component
consists of royalty paid to third party software companies for the right to
incorporate their product in Oberon's software.

     Cost of Services Revenue. Cost of services revenue increased to $403,000,
or 104% of services revenue, for the year ended September 30, 1998 from
$331,000, or 195% of services revenue, for the year ended September 30, 1998.
The increase in the cost of services was primarily attributed to increased
staffing personnel as Oberon hired consultants to assist the customers in the
implementation of the software.

     Operating Expenses

     Research and Development. Research and development expenses increased to
$2.4 million for the year ended September 30, 1998 from $1.5 million for the
year ended September 30, 1997. The increase primarily resulted from an increase
in staffing as the company started investing in software development to assist
in the implementation of software from the enterprise revenue planning software
companies.

     Sales and Marketing. Sales and marketing expenses decreased to $2.9 million
for the year ended September 30, 1998 from $3.2 million for the year ended
September 30, 1997. The decrease was primarily attributable to reducing costs
associated with the indirect sales channel on a world wide basis as part of
Oberon's strategy to emphasize sales to major corporations in North America
through direct sales.

     General and Administrative. General and administrative expenses decreased
to $1.3 million for the year ended September 30, 1998 from $1.4 million for the
year ended December 31, 1997.

     Other Income (Expense). Interest income increased to $209,000 for the year
ended September 30, 1998 from $111,000 for the year ended September 30, 1997 due
to higher average cash balance. Interest expense decreased to $126,000 for the
year ended September 30, 1998 from $144,000 for the year ended September 30,
1997. Other expense decreased to $8,000 for the year ended September 30, 1998
from $16,000 for the year ended September 30, 1997.

LIQUIDITY AND CAPITAL RESOURCES

     Since its inception, Oberon has funded operations primarily through net
cash proceeds from private placements of preferred stock totaling $38.9 million
through December 31, 1999. As of December 31, 1999, Oberon had cash and cash
equivalents totaling $8.0 million.

     Cash used for operating activities for the three month period ended
December 31, 1999 was $2.1 million, primarily due to a net loss of $2.2 million
and a decrease in accounts payable, accruals and deferred revenue partially
offset by decreases in accounts receivables and prepaid expenses. Cash used for
operating activities for the year ended September 30, 1999 was $5.8 million,
primarily due to a net loss of $6.3 million and an increase in accounts
receivable, partially offset by increases in accrued expenses and deferred
revenue.

                                       108
<PAGE>   115

     Cash used for investing purposes for the three month period ended December
31, 1999 was $89,000 and for the year ended September 30, 1999 was $615,000.
Investing activities for both periods primarily consisted of purchases of
computers, networking equipment and software for internal use.

     No cash was provided by financing activities for the three month period
ended December 31, 1999. Cash provided by financing activities for the year
ended September 30, 1999 was $11.5 million, due to the issuance of preferred
stock for net proceeds totaling $7.3 million, the borrowing of $4 million from
Comdisco Ventures and $284,000 on an available equipment line of credit to
finance investing activities.

     Oberon's primary financial commitments consisted of $165,000 payable under
an equipment lease, a loan payable under the equipment line of credit of
$284,000 and a loan payable to Comdisco Ventures in the amount of $4 million as
of December 31, 1999 and $183,000, $284,000 and $4 million respectively as of
September 30, 1999.

     As of September 30, 1999, Oberon has net operating loss carryforwards and
research tax credit carryforwards of approximately $32 million and $1.13
million, respectively, available to reduce future federal and state income taxes
payable to the extent permitted under the Internal Revenue Code, expiring in
varying amounts through 2014. The net operating loss carryforwards and research
tax credit carryforwards will be subject to the limitations provided in Internal
Revenue Code sections 382 and 383.

     Oberon has a deferred tax asset at September 30, 1999 of approximately
$12.1 million, attributable primarily to net operating loss and research tax
credit carryforwards. This asset has been fully offset by a valuation allowance
at September 30, 1999. The valuation allowance increased approximately $2.3
million during 1999.

     Management believes that the company has the financial resources and
ability to meet its business and financial obligations in the normal course of
business through December 31, 2000.

YEAR 2000 READINESS DISCLOSURE

     The "Year 2000 Issue" refers generally to problems that some software
programs may have in determining the correct century for the year. For example,
software and computer systems with date-sensitive functions that are not Year
2000 compliant may not be able to distinguish whether "00" means 1900 or 2000,
which may result in failures or the creation of erroneous results.

     Oberon has defined "Year 2000 compliant" as the ability to:

     - correctly handle date information needed for changes after December 31,
       1999;

     - function according to the product documentation provided for this date
       change, without changes in operation, assuming correct configuration;

     - where appropriate, respond to two-digit date input in a way that resolves
       the ambiguity as to century in a disclosed, defined, and predetermined
       manner;

     - store and provide output of date information in ways that are unambiguous
       as to the century if the date elements in interfaces and data storage
       specify the century; and

     - recognize the year 2000 as a leap year.

     The risks imposed by Year 2000 issues could adversely affect Oberon's
business in a number of significant ways. Although Oberon believes that its
internally developed systems and technology are Year 2000 compliant, the
information and non-information technology systems Oberon uses nevertheless
could be substantially impaired or cease to operate due to Year 2000 problems.
Additionally, Oberon relies on information technology supplied by third parties.

     To date, Oberon has experienced no material adverse effects on any of its
products due to the transition to Year 2000. Oberon cannot assure you that it
will not experience problems resulting from any of the foregoing which could
have a material adverse impact on its business, operating results or financial

                                       109
<PAGE>   116

condition, that the implementation of modifications to any embedded products
will not be delayed or that Oberon will not experience unexpected Year 2000
problems with its products.

     Oberon has conducted a Year 2000 readiness review for all versions of its
products after version 2.0. This review included assessment, validation, testing
and, where necessary, remediation, upgrading and replacement of product
versions. Oberon continues to respond to customer questions about prior versions
of its products on a case-by-case basis.

     Based on Oberon's review, it believes the versions of its products that it
currently ships are Year 2000 compliant, when configured and used in accordance
with the related documentation, so long as the underlying operating system of
the host machine and any other software used with or in the host machine or with
its products are also Year 2000 compliant. Oberon is currently shipping version
3.0 of its product. Oberon does not believe that versions of its products prior
to version 2.0 are Year 2000 compliant, and has notified its customers of this
fact and encouraged users of these versions to upgrade to the latest version.
Oberon does not provide software patches or remedial software programs for
versions of its products prior to version 2.0. Oberon's customers who have
maintenance agreements with it each have the right to receive the latest version
of our products without additional charge. Oberon's customers who do not have
maintenance agreements may purchase the latest version of its products.

     Oberon has not separately tested software obtained from third parties that
is incorporated into its products. Oberon has tested this third-party software
as incorporated in its products as part of its product review. While Oberon
believes that the third party software as incorporated in the current versions
of its products is Year 2000 compliant, it has not been able to obtain
assurances from all vendors.

     Errors or defects in Oberon's products could result in delay or loss of
revenues, diversion of development resources, damage to reputation, increased
service and warranty costs, or liability to its customers, any of which could
materially and negatively affect Oberon's business and operating results. Some
commentators have predicted significant litigation regarding Year 2000
compliance issues.

     Oberon has completed an assessment of its material internal information
technology systems, including both software products and third-party software
and hardware. Oberon has also completed an assessment of its non-information
technology systems. To the extent that Oberon is not able to test the technology
provided by third party vendors, it is seeking assurances from these vendors
that their systems are Year 2000 compliant. Oberon is not currently aware of any
material operational issues associated with preparing its internal information
technology and non-information technology systems for the Year 2000. However,
Oberon may experience material unanticipated problems and costs caused by
undetected errors or defects in the technology used in its internal information
technology and non-information technology systems.

     If Oberon's customers are not Year 2000 compliant, they may incur material
costs to remedy problems, or they may face litigation expenses.

- ---------------
(1) Stock options were granted under Oberon's 1998 Stock Incentive Plan, as
    amended, at an exercise price equal to the fair market value of the Oberon
    common stock on the date of grant. Some options have a term of 5 1/2 years
    from the date of grant and become exercisable as to 20% of the shares
    covered on the first anniversary following the date of grant and as to an
    additional 5% of the original number of shares at the end of each successive
    full, three-month period. Other options have a term of 4 1/2 years from the
    date of grant and become exercisable as to 25% of the shares covered at the
    end of the first anniversary following the date of grant and as to an
    additional 6.25% of the original number of shares at the end of each
    successive full three-month period. Any shares subject to the Plan which
    have not already vested but would vest within 18 months after the closing of
    the merger will vest and become exercisable upon the closing of the merger.

(2) Amounts reported in these columns represent amounts that may be realized
    upon exercise of the options immediately prior to the expiration of their
    term assuming specified compounded rates of appreciation (5% and 10%) on
    Oberon common stock over the term of the options. These numbers are
    calculated based on rules promulgated by the Securities and Exchange
    Commission and do not reflect Oberon's estimate of future stock price
    growth. Actual gains, if any, on stock option exercises and common stock
    holdings are dependent on the timing of such exercise and the future
    performance of Oberon's common stock. There can be no assurance that the
    rates of appreciation assumed in this table can be achieved or that the
    amounts reflected will be received by the individuals.

                           RELATED PARTY TRANSACTIONS

     Upon completion of the merger, M. McMahon and M. Wick, have agreed to be
employees of OnDisplay and J. Chappell and D. Collard have agreed to enter into
severance agreements with OnDisplay in the form attached to the merger
agreement. For more information relating to these employment agreements, please
see the section entitled "Employment Agreements" under the caption "Agreements
Related to the Merger" on page 64 of this proxy statement/prospectus.

     Some of the directors and officers of Oberon participate in arrangements
and have continuing indemnification against liabilities that provide them with
interests in the merger that are different from, or are in addition to, your
interests.

     Under the merger agreement, OnDisplay has agreed to cause the corporation
surviving the merger to honor Oberon's obligations under indemnification
agreements between Oberon and its directors and officers in effect before the
completion of the merger and any indemnification provisions of Oberon's articles
of incorporation and bylaws. OnDisplay has also agreed to provide for
indemnification provisions in the articles of incorporation and bylaws of the
surviving corporation of the merger that are at least as favorable as Oberon's
provisions.

     As a result of these interests, these directors and officers of Oberon
could be more likely to vote to approve the merger agreement than if they did
not hold these interests. Oberon's stockholders should

                                       112
<PAGE>   119

consider whether these interests may have influenced these directors and
officers to support or recommend the merger.

          AGGREGATE OPTION EXERCISES IN FISCAL 1999 AND OPTION VALUES

     The following table sets forth certain information regarding stock options
exercised during the fiscal year ended September 30, 1999. There was no public
trading market for Oberon common stock as of September 30, 1999. Accordingly,
the unexercised stock options had no value as of September 30, 1999.

                                 PROPOSAL NO. 1

                    APPROVAL OF AMENDMENT TO 1996 STOCK PLAN

     OnDisplay stockholders are being asked to approve an amendment to the 1996
Stock Plan to provide for an increase in the number of shares of common stock
reserved for issuance from 4,975,000 shares to 6,975,000 shares. The board
believes that adding these shares to the plan is in the best interests of
OnDisplay because they will be needed to attract and retain key employees whose
efforts are critical to OnDisplay's success. Competition for key personnel is
intense, particularly in the San Francisco Bay area where our headquarters is
located. The plan plays an important role in OnDisplay's efforts to attract and
retain employees of outstanding ability.

     The board of directors adopted the 1996 Stock Plan on August 13, 1996 and
the stockholders initially approved the 1996 Stock Plan on September 17, 1996.
Set forth below is a summary of the principal features of the 1996 Stock Plan.
OnDisplay will provide, without charge, to each person to whom a proxy statement
is delivered, upon request of such person and by first class mail within three
business days of receipt of such request, a copy of the 1996 Stock Plan. Any
such request should be directed as follows: Secretary, OnDisplay, Inc., 12667
Alcosta Boulevard, Suite 300, San Ramon, CA 94583; telephone number (925)
480-2000.

ONDISPLAY'S 1996 STOCK PLAN

     The 1996 Stock Plan provides for the grant of incentive stock options
within the meaning of Section 422 of the Internal Revenue Code to employees, and
for the grant of nonstatutory stock options and stock purchase rights to
employees, directors and consultants.

  Number of Shares of Common Stock Available under the 1996 Stock Plan

     As of December 31, 1999, 4,975,000 shares of common stock were authorized
for issuance pursuant to the 1996 Stock Plan, of which options to acquire
2,986,985 shares were issued and outstanding as of that date and 182,225 shares
remained available for future option grants. On January 25, 2000 and February
29, 2000, the board of directors approved an increase of a total of 2,000,000
shares under the plan. The stockholders are being asked to approve this increase
at the special meeting. The 1996 Stock Plan provides for annual increases in the
number of shares available for issuance thereunder, on the first day of each new
fiscal year, effective beginning with fiscal year 2001, equal to the lesser of
4.0% of the outstanding shares of common stock on the first day of the fiscal
year, or 1,000,000 shares.

  Administration of the 1996 Stock Plan

     The administrator of the 1996 Stock Plan, which may be either the board of
directors or a committee of the board of directors, administers the 1996 Stock
Plan. In the case of options intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Internal Revenue Code,
the committee will consist of two or more "outside directors" within the meaning
of Section 162(m) of the Internal Revenue Code. The administrator has the power
to determine the terms of the options or stock purchase rights granted,
including the exercise price, the number of shares issuable upon exercise of
each option or stock purchase right, the exercisability of the options and the
form of consideration payable upon exercise.

  Options

     The administrator determines the exercise price of nonstatutory stock
options granted under the 1996 Stock Plan, 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
at least be equal to the fair market value of the common stock on the date of
grant. The exercise price of all incentive stock options granted under the 1996
Stock Plan must be at least equal to the fair
                                       115
<PAGE>   122

market value of the common stock on the date of grant and the term of such
option may not exceed ten years. With respect to any participant who owns stock
possessing more than 10% of the voting power of all classes of our outstanding
capital stock, the exercise price of any incentive stock option granted must
equal at least 110% of the fair market value on the grant date and the term of
such incentive stock option must not exceed five years. The administrator
determines the term of all other options.

     No optionee may be granted an option to purchase more than 500,000 shares
in any fiscal year. In connection with his or her initial service, an optionee
may be granted an option to purchase up to an additional 500,000 shares, which
shall not count against the yearly limit set forth in the previous sentence.

     An optionee generally must exercise an option granted under the 1996 Stock
Plan at the time set forth in the optionee's option agreement after termination
of the optionee's status as an employee, director or consultant. Generally, in
the case of the optionee's termination by death or disability, the option will
remain exercisable for twelve months. In all other cases, the option will
generally remain exercisable for a period of three months. However, an option
may never be exercised later than the expiration of the option's term.

  Stock Purchase Rights

     The administrator determines the exercise price of stock purchase rights
granted under the 1996 Stock Plan. In the case of stock purchase rights, unless
the administrator determines otherwise, the restricted stock purchase agreement
entered into in connection with the exercise of the stock purchase right shall
grant us a repurchase option that we may exercise upon the voluntary or
involuntary termination of the purchaser's service with us for any reason,
including death or disability. The purchase price for shares we repurchase
pursuant to restricted stock purchase agreements shall generally be the original
price paid by the purchaser and may be paid by cancellation of any indebtedness
of the purchaser to us. The repurchase option shall lapse at a rate that the
administrator determines.

  Transferability of Options and Stock Purchase Rights

     An optionee generally may not transfer options and stock purchase rights
granted under the 1996 Stock Plan and only the optionee may exercise an option
and stock purchase right during his or her lifetime.

  Adjustments upon Merger or Asset Sale

     The 1996 Stock Plan provides that in the event of a merger, sale or
reorganization of OnDisplay with or into any other corporation or the sale of
all or substantially all of the assets or outstanding stock of OnDisplay, in
which transaction our stockholders immediately prior to such transaction own
immediately after such transaction less than 50% of the equity securities of the
surviving corporation, vesting of outstanding options shall accelerate by 18
months. The 1996 Stock Plan also provides that in the event of a merger of
OnDisplay with or into another corporation, the successor corporation shall
assume or substitute for each option or stock purchase right. If the outstanding
options or stock purchase rights are not assumed or substituted, the
administrator shall provide notice to the optionee that he or she has the right
to exercise the option or stock purchase right as to all of the shares issuable
upon exercise of the option or stock purchase right, including unvested shares,
for a period of 15 days from the date of the notice. Any unexercised portion of
an option or stock purchase right will terminate upon the expiration of the
15-day period.

  Amendment and Termination of the 1996 Stock Plan

     Unless terminated sooner, the 1996 Stock Plan will terminate automatically
in 2006. In addition, the Board of Directors has the authority to amend, suspend
or terminate the 1996 Stock Plan, provided that no such action may affect any
share of common stock previously issued and sold or any option previously
granted under the 1996 Stock Plan.

  Stock Options Granted to Executive Officers

     The table on page 98 shows the stock options granted to the Named Executive
Officers in 1999. There were no grants to the Named Executive Officers from the
shares added to the 1996 Stock Plan by the amendment that is proposed to be
approved at the special meeting.

     THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE
AMENDMENT TO THE 1996 STOCK PLAN.

                                 PROPOSAL NO. 2

                 APPROVAL OF 1999 EMPLOYEE STOCK PURCHASE PLAN

     OnDisplay stockholders are being asked to approve the 1999 Employee Stock
Purchase Plan. The purchase plan, which is intended to qualify under Section 423
of the Internal Revenue Code, is similar to purchase plans adopted by many
companies with which OnDisplay competes to hire and retain qualified personnel.
Our board of directors, which approved the purchase plan in July 1999, believes
that it provides an incentive to such personnel by affording them an attractive
opportunity to purchase OnDisplay share.

     Set forth below is a summary of the principal features of the 1999 Employee
Stock Purchase Plan. OnDisplay will provide, without charge, to each person to
whom a proxy statement is delivered, upon request of such person and by first
class mail within three business days of receipt of such request, a copy of the
1999 Employee Stock Purchase Plan. Any such request should be directed as
follows: Secretary, OnDisplay, Inc., 12667 Alcosta Boulevard, Suite 300, San
Ramon, CA 94583; telephone number (925) 480-2000.

ONDISPLAY'S 1999 EMPLOYEE STOCK PURCHASE PLAN

  Number of Shares of Common Stock Available under the Purchase Plan

     A total of 1,500,000 shares of common stock is available for issuance under
the purchase plan. In addition, the purchase plan provides for annual increases
in the number of shares available for issuance under the purchase plan on the
first day of each fiscal year, beginning with the fiscal year 2001, equal to the
lesser of 1.5% of the outstanding shares of common stock on the first day of the
fiscal year, 350,000 shares, or such other amount as may be determined by the
board.

  Administration of the Purchase Plan

     The board of directors or a committee appointed by the board of directors
administers the purchase plan. The board of directors or its committee has
exclusive authority to interpret the terms of the purchase plan.

  Eligibility to Participate

     Employees are eligible to participate if they are customarily employed by
OnDisplay or any participating subsidiary for at least 20 hours per week and
more than five months in any calendar year. However, an employee may not
participate:

     - if such employee owns or holds options to purchase (including purchase
       rights under the purchase plan) 5% or more of the total capital stock of
       OnDisplay; or

     - if such employee's rights to purchase stock under all employee stock
       purchase plans of OnDisplay accrues at a rate that exceeds $25,000 for
       the calendar year.

  Offering Periods, Payroll Deductions and Purchases

     The purchase plan contains consecutive, overlapping 24-month offering
periods. Each offering period includes four 6-month purchase periods. The
offering periods generally start on the first trading day on or

                                       117
<PAGE>   124

after May 1 and November 1 of each year, except for the first such offering
period which commenced on December 17, 1999 and will end on the last trading day
on or before October 31, 2001.

     The purchase plan permits participants to purchase common stock through
payroll deductions of up to 15% of the participant's eligible compensation,
which includes the participant's base straight time gross earnings, commissions
and cash incentive compensation, but exclusive of payments for overtime, shift
premium, bonuses and other compensation. The maximum number of shares a
participant may purchase during a six-month purchase period is 10,000 shares.

     Amounts deducted and accumulated by the participant are used to purchase
shares of OnDisplay common stock at the end of each six-month purchase period.
The price is 85% of the market value of OnDisplay common stock at the beginning
of the offering period, or, if lower, at the end of the purchase period. In the
event the market value at the end of a purchase period is less than the market
value at the beginning of the offering period, participants will be withdrawn
from the current offering period following their purchase of shares and will be
automatically re-enrolled in the new offering period that begins immediately
after the date of their purchase. Participants may end their participation at
any time during an offering period, and they will be paid their accumulated
payroll deductions through the withdrawal date. Participation ends automatically
upon termination of employment.

  Transferability of Rights

     A participant may not transfer rights granted under the purchase plan other
than by will, the laws of descent and distribution or otherwise provided under
the purchase plan.

  Adjustments upon Merger or Asset Sale

     The purchase plan provides that, in the event of a merger of OnDisplay with
or into another corporation or a sale of all or substantially all of our assets,
a successor corporation may assume or substitute for each outstanding option. 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.

  Amendment and Termination of the Purchase Plan

     The purchase plan will terminate in 2009. However, the board of directors
has the authority to amend or terminate the purchase plan, except that,
contingent on some exceptions described in the purchase plan, no such action may
adversely affect any outstanding rights to purchase stock under the purchase
plan.

                                 LEGAL OPINION

     The validity of the shares of OnDisplay common stock offered by this proxy
statement/prospectus will be passed upon for OnDisplay by Wilson Sonsini

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of
OnDisplay, Inc.

     In our opinion, the accompanying balance sheet and the related statements
of operations, changes in stockholders' equity (deficit) and cash flows present
fairly, in all material respects, the financial position of OnDisplay, Inc. at
December 31, 1999 and 1998 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 generally accepted accounting principles in the United States. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- BUSINESS:

     OnDisplay, Inc. (the "Company") develops and markets applications for
powering e-business portals and e-marketplaces in both business-to-business and
business-to-consumer e-commerce. The Company's product suite provides an open,
scalable, adaptable solution to enable the rapid aggregation, exchange,
integration, personalization and syndication of e-business information and
services from a broad range of partners, suppliers and customers. Through the
use of the internet, customers are able to align information systems of business
allies without modification to existing applications or to migrate rapidly from
their existing systems to new enterprise applications. The Company operates in a
single business segment and does not have any separately reportable business
segments as of December 31, 1999.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES:

MANAGEMENT ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. These estimates include levels of reserves for accounts
receivable, valuation of deferred tax assets and value of the Company's capital
stock. Actual results could differ from these estimates.

CASH AND CASH EQUIVALENTS

     The Company considers all investments purchased with an original or
remaining maturity of three months or less to be cash equivalents.

CONCENTRATION OF CREDIT RISK

     The Company maintains its cash and cash equivalents in accounts with two
major financial institutions in the United States. The Company has not
experienced any losses on its deposits of cash and cash equivalents.

     The Company performs ongoing credit evaluations of its customers, and
collateral is not required. The Company records an allowance for doubtful
accounts for credit losses at the end of each period based on an analysis of
individual aged accounts receivable balances. As a result of this analysis, the
Company believes that its allowance for doubtful accounts is adequate but no
excessive at December 31, 1998 and 1999.

     At December 31, 1999 two customers accounted for 21% and 15% of accounts
receivable and at December 31, 1998 two different customers accounted for 24%
and 12% of accounts receivable.

     The Company derives most of its license service and support revenues from
one suite of products.

     In 1997, these customers represented 21%, 30% and 37% of total revenues and
in 1998 two customers represented 11% and 13% of total revenues. No customer
accounted for more than 10% of total revenues in 1999.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of certain of the Company's financial instruments,
including cash, cash equivalents, trade accounts receivable, accounts payable
and accrued liabilities approximate fair value due to their short maturities.
Based on borrowing rates currently available to the Company for loans with
similar terms, the carrying value of its long-term debt approximates fair value.

<PAGE>   134
                                ONDISPLAY, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful life of the related assets of
three years. Leasehold improvements and leased assets are amortized on a
straight line basis over the lesser of their estimated useful life or the lease
term. Gains and losses from the disposal of property and equipment are taken
into income in the year of disposition. Repairs and maintenance costs are
expensed as incurred.

REVENUE RECOGNITION

     Revenue consists of revenue earned under software license agreements,
service agreements, and maintenance agreements,. Revenue from software license
agreements is recognized upon shipment or upon notification to the customer of
the downloadable software location, provided that a signed contract exists, the
fee is fixed and determinable and collection of the resulting receivable is
probable and, if applicable, acceptance criteria are met. In cases where a fee
is due to a referring party under the Company's referral agreements, such fees
are recorded as sales and marketing expenses when the accompanying sales are
recorded.

     For contracts with multiple obligations (e.g., deliverable and
undeliverable products, maintenance, installation and other services), revenue
is allocated to each component of the contract based on objective evidence of
its fair value, which is specific to the Company, or for products not being sold
separately, the price established by management. The Company recognizes revenue
allocated to undelivered products when the criteria for product revenue set
forth above are met. The Company recognizes revenue from maintenance fees,
including amounts allocated from product revenues for ongoing customer support
and product updates ratably over the period of the maintenance contract.
Payments for maintenance fees are generally made in advance and are
non-refundable. For revenue allocated installation and training and for such
services sold separately, the Company recognizes revenue as the related services
are performed.

     Deferred revenue consists of payments received prior to delivery of
licenses, fulfillment of acceptance criteria, or performance of services.

COST OF REVENUES

     Cost of license revenues includes costs associated with the electronic
transmission of software and royalties for third party embedded software which
were not material. Cost of service revenue includes salaries and related
expenses for the service organization and cost of third parties contracted to
provide services to customers.

RESEARCH AND DEVELOPMENT EXPENDITURES

     Expenditures for research and development are charged to expense as
incurred. Under Statement of Financial Accounting Standards ("SFAS") No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise
Marketed" certain software development costs are capitalized after technological
feasibility has been established. Development costs incurred in the period
between achievement of technological feasibility, which the Company defines as
the establishment of working model, until the general availability of such
software to customers, has been short and software development costs qualifying
for capitalization have been insignificant. Accordingly, the Company has not
capitalized any software development costs to date.

STOCK-BASED COMPENSATION

     Pursuant to SFAS No. 123, "Accounting for Stock-Based Compensation," the
Company accounts for employee stock options under Accounting Principles Board
Opinion ("APB") No. 25 and follows the
                                       F-8
<PAGE>   135
                                ONDISPLAY, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

disclosure-only provisions of SFAS 123. Under APB No. 25, compensation expense
is based on the difference, if any, on the date of grant, between the estimated
fair value of the Company's stock and the exercise price of options to purchase
that stock.

INCOME TAXES

     Deferred income tax assets and liabilities are computed for differences
between the financial statement and tax bases of assets and liabilities that
will result in taxable or deductible amounts in the future based on enacted tax
laws and rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary to
reduce deferred tax assets to the amount expected to be realized.

NET LOSS PER SHARE

     Basic net loss per share is computed by dividing net loss available to
common stockholders by the weighted average number of vested common shares
outstanding for the period. Diluted net loss per share is computed giving effect
to all dilutive potential common stock, including nonvested common stock,
options, warrants and preferred stock. Options, warrants, common stock subject
to repurchase and preferred stock were not included in the computation of
diluted net loss per share in the periods reported because the effect would be
antidilutive.

     Antidilutive securities not included in net loss per share calculation for
the periods:

     Effective January 1, 1998, the Company adopted the provisions of SFAS No.
130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards for
reporting comprehensive income and its components in financial statements.
Comprehensive income, as defined, includes all changes in equity (net assets)
during a period from non-owner sources. The Company has no comprehensive income
components other than its net loss.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments and hedging activities and will be adopted
in the year 2000. It requires that an entity recognize all derivatives as either
assets or liabilities in the balance sheet and measure those instruments at fair
value. The Company is in process of evaluating the impact of this pronouncement.

     In December 1998, the Accounting Standards Executive Committee issued
Statement of Position 98-9, modification of SOP 97-2, "Software Revenue
Recognition," with Respect to Certain Transactions. SOP 98-9 will be effective
for transactions that are entered into in fiscal years beginning after March 15,
1999. Retroactive application is prohibited. The Company believes the adoption
of 98-9 will not have a material impact on its results of operation.

DIVIDENDS

     The holders of Series A, Series B, Series C and Series D preferred stock
are entitled to receive the above annual dividends, when and if declared by the
Board of Directors. After payment of any required dividends to the Series A,
Series B, Series C and Series D stockholders, declared dividends shall be
distributed among all holders of common stock and all holders of Series A,
Series B, Series C and Series D preferred stock in proportion to the number of
shares of common stock which would be held by each such holder if all shares of
Series A, Series B, Series C and Series D preferred stock were converted to
common stock. Dividends declared by the Company are contingent on approval by
the lender of the long-term loan.

LIQUIDATION

     In the event of any liquidation, dissolution, or winding up of the Company,
either voluntary or involuntary, the holders of Series A, Series B, Series C and
Series D preferred stock are entitled to receive, prior and in preference to any
distribution of any of the assets of the Company to the holders of common stock
by reason of their ownership, an amount equal to the sum of $1.00, $2.10, $4.00
and $9.52 for each outstanding share of Series A, Series B, Series C and Series
D preferred stock, (as adjusted for any stock dividends, combinations or splits)
plus any declared but unpaid dividends on such shares. If upon the occurrence of
such event, the assets distributed among the holders of preferred stock are
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then the entire assets of the Company legally available
for distribution are to be distributed first ratably among the holders of the
preferred stock in proportion to the aggregate liquidation preference of the
shares of preferred stock then held by them.

     After payment has been made to the holders of preferred stock, any
remaining assets and funds are to be distributed pro rata among the holders of
the preferred stock and the common stock on a per share basis, treating all
shares of preferred stock convertible into shares of common stock as if
converted; provided, however, that after the receipt by each share of preferred
stock of distributions equal to two times the original purchase price for the
preferred stock, then all remaining assets shall be distributed equally among
the holders of the common stock on a per-share basis.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

CONVERSION

     Each share of preferred stock, at the option of the holder thereof, shall
be convertible into such number of fully paid and nonassessable shares of common
stock which results from dividing the issuance price per share by the conversion
price per share in effect for the shares of preferred stock at the time of
conversion. The issuance price per share and initial conversion price per share
of Series A, B, Series C and Series D preferred stock are $1.00, $2.10, $4.00
and $9.52. The number of shares of common stock into which a share of a series
of preferred stock is convertible is referred to as the conversion rate of such
series. The initial conversion prices of Series A, B, C and D preferred stock
may be adjusted under circumstances described in the Company's Restated Articles
of Incorporation. At December 31, 1998 and September 30, 1999 the conversion
ratio was one to one.

     Conversion is automatic at the then effective conversion price of such
series immediately prior to the closing of a qualified initial public offering
at an aggregate offering price to the public of not less than 20 million
provided that the Series A, B and C preferred stock shall not be converted
without the majority approval of such series, and the Series D preferred stock
shall not be converted without the approval by more than 2/3 of the holders of
Series D preferred stock.

VOTING

     The holders of Series A, Series B, Series C and Series D preferred stock
are entitled to voting rights equal to the number of shares of common stock into
which each share of preferred stock could be converted at the record date for a
vote or consent of stockholders, except as otherwise required by law, and have
voting rights and powers equal to the voting rights and powers of the shares of
common stock.

REDEMPTION

     Preferred stock shall be redeemable at the option of the holders of a
majority of the outstanding shares of preferred stock at any time after
September 30, 2001 if the Company has not completed a firm commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
common stock for the account of the Corporation with an aggregate offering price
to the public of not less than $20,000,000 defined hereafter as a "Qualified
IPO." Such redemption right may be exercised by giving at least 120 day notice
prior to the date of commencement of the redemption. After receipt of such
notice of a redemption, the Company shall redeem all of the outstanding shares
of preferred stock in three equal annual installments on the last day of each
fiscal year (commencing with the first fiscal year ending after the 120 day
notice period). The redemption price of the preferred stock shall be the
original purchase price per share (as adjusted for any stock dividends,
combinations or splits) plus any accrued but unpaid dividends. Any redemption of
only a part of the outstanding preferred stock by the Company shall be pro rata
as among all holders of preferred stock in proportion to the aggregate
redemption price to be paid to such holders.

NOTE 8 -- STOCK OPTION AND STOCK PURCHASE PLANS:

STOCK OPTION PLAN

     Under the Company's 1996 Stock Plan as amended, incentive options to
purchase the Company's common stock may be granted to employees at prices not
lower than the fair market value per share on the date of grant, as determined

their options prior to complete vesting of shares, subject to the Company's
right of repurchase, such that, in the event of a termination of the optionee's
employment or consulting relationship, any unvested shares may be repurchased at
a price per share equal to the original exercise price per share for the option.
Unexercised vested options expire three months after termination of employment
with the Company. Shares repurchased by the Company were none, 41,394 and 71,554

</TABLE>

     For financial reporting purposes, the Company has determined that the
estimated value of common stock was in excess of the exercise price, which was
considered to be the fair market value as of the date of grant for 781,750
options issued in 1998 and 3,152,650 options issued in 1999. In connection with
the grants of such options, the Company has recognized deferred compensation of
approximately $2,220,000 in 1998 and $31,268,000 in 1999. Deferred stock-based
compensation will be amortized over the vesting period which is generally 48
months from the date of grant; approximately $618,000 was expensed in the year
ended December 31, 1998 and $3,697,000 in the year ended December 31, 1999.
Future amortization based on options granted through December 31, 1999 is
expected to be $15,441,000 and $7,987,000, $4,166,000 and $1,581,000 in the
years 2000, 2001, 2002 and 2003.

NOTE 9 -- WARRANTS:

     As part of a long-term borrowing agreement entered into in February 1999,
the Company issued a warrant to purchase an aggregate of 85,537 shares of common
stock at an exercise price of $6.05 per share. The warrant were exercisable upon
grant and expire in January 2009.

     The Company valued the warrant using the Black-Scholes method. The fair
value of $535,000 is amortized to interest expense over the term of the
long-term loan.

NOTE 10 -- INCOME TAXES:

     At December 31, 1999, the Company had net operating loss carryforwards of
approximately $23,800,000 and $18,600,000 for Federal and California purposes,
respectively, available to reduce future taxable income, if any. These
carryforwards expire through 2019 and 2004 for Federal and California purposes,
respectively, if not utilized beforehand.

     At December 31, 1999, the Company had research and development credit
carryforwards of approximately $479,000 and $302,000 for Federal and California
income tax purposes, respectively. The research and development credit
carryforwards expire beginning in the year 2011.

     The Tax Reform Act of 1986 limits the use of net operating loss and tax
credit carryforwards in certain situations where changes occur in the stock
ownership of a company. In the event the Company has had a change in ownership,
utilization of the carryforwards could be restricted.

     Temporary differences which gave rise to significant portions of deferred
tax assets and liabilities are as follows (in thousands):

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Oberon Software Incorporated

     We have audited the accompanying balance sheets of Oberon Software
Incorporated (the Company) as of September 30, 1999 and 1998, and the related
statements of operations, stockholders' equity (deficit), and cash flows for
each of the three years in the period ended September 30, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in 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 Oberon Software Incorporated
at September 30, 1999 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended September 30, 1999 in
conformity with accounting principles generally accepted in the United States.

                         NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1999

1. THE COMPANY AND ITS CAPITALIZATION

     Oberon Software Incorporated (the Company) is a leading provider of
e-business integration solutions. The Company's software provides an
unparalleled approach to integration that delivers rapid, flexible and highly
maintainable solutions for dynamic collaboration among employees, partners,
suppliers and their customers. The Company operates and reviews the performance
of the business as one segment and substantially all its sales are with in the
United States

     The environment of rapid technological change and intense competition which
is characteristic of the software development industry results in frequent new
products and evolving industry standards. The Company's ultimate success depends
largely upon its ability to enhance current products and develop new products on
a timely basis which keep pace with the changes in technology and competitors'
innovations.

     In 1999, the Company issued 2,919,598 shares of Series 2 Convertible
Non-Participating Preferred Stock in exchange for net proceeds of $7,269,033 in
cash. The Company also entered into a subordinated loan and security agreement
from which the Company received $4,000,000 in cash. Management believes that the
proceeds from these transactions combined with cash from operations will allow
the Company to operate through 2000.

2. SIGNIFICANT ACCOUNTING POLICIES

REVENUE RECOGNITION

     The Company recognizes revenues in accordance with Statement of Position
97-2, (SOP 97-2), Software Revenue Recognition, issued by the American Institute
of Certified Public Accountants. Under the provisions of SOP 97-2, revenue
related to the elements of software arrangements are recognized separately if no
significant modification or customization of the software is required and vendor
specific objective evidence of the pricing of each element of the arrangement
exists. Accordingly, revenue from software product sales is recognized upon
delivery of the software; services revenues are recognized as provided and
maintenance fees are recognized ratably over the term of the maintenance
agreement. The Company accrues the estimated cost of warranty and product
returns in the period in which the product revenue is recognized; historically,
these amounts have not been material.

     Royalties are recognized at the time the Company's third-party distributors
license the Company's software to their customers.

RESEARCH AND DEVELOPMENT COSTS

     Development costs incurred in the research and development of new software
products and enhancements are expensed as incurred to research and development
until technological feasibility has been established. After technological
feasibility is established, any additional development costs are capitalized in
accordance with Statement of Financial Accounting Standards No. 86, Accounting
for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed.
Capitalized software costs are amortized over their estimated economic lives. As
of September 30, 1999, no eligible costs have been capitalized due to the
uncertainty of their recoverability.

CONCENTRATIONS OF CREDIT RISK

     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash equivalents and
accounts receivable. Cash equivalents consist of temporary investments in money
market funds with maturity dates of three months or less and have limited credit
exposure. The risk with respect to accounts receivable is minimized by the
creditworthiness of the Company's customers and the Company's credit and
collection policies.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                               SEPTEMBER 30, 1999

USE OF ESTIMATES

     The preparation of the Company's financial statements under generally
accepted accounting principles requires management to make significant estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost and depreciated by the
straight-line method over estimated useful lives of three years. Capital lease
assets are depreciated over the estimated useful life or the term of the lease,
whichever is shorter.

STOCK-BASED COMPENSATION

     The Company grants stock options for a fixed number of shares to employees
with an exercise price equal to the fair value of the shares at the date of the
grant. The Company accounts for stock option grants to employees and directors
in accordance with Accounting Principles Board Opinion (APB) No. 25, Accounting
for Stock Issued to Employees, which is based on the intrinsic value method of
measuring stock-based compensation. The Company has adopted the disclosure
provisions only of Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation (SFAS 123), which is based on the
fair-value method of measuring stock-based compensation.

LOSS PER SHARE

     Loss per share is presented in accordance with SFAS No. 128, Earnings Per
Share, which requires the disclosure of basic and diluted earnings (loss) per
share. Basic loss per share is based upon the Company's net loss divided by the
number of weighted shares outstanding during the reporting period. Diluted loss
per share for loss periods is the same as basic loss per share since the effects
of including the conversion of preferred stock and common stock equivalents of
warrants and options is anti-dilutive.

INCOME TAXES

     The Company provides for income taxes under Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109). Under SFAS
109, the liability method is used in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.

RECLASSIFICATIONS

     Certain amounts in 1998 have been reclassified to permit comparison with
1999.

INTERIM REPORTING

     The interim unaudited condensed financial statements have been prepared by
the Company pursuant to the rules and regulations of the Securities and Exchange
Commission and in accordance with generally accepted accounting principles.
Accordingly, certain information and footnotes disclosure normally included in
annual financial statements have been omitted or condensed. In the opinion of
management, all necessary adjustments (consisting of only normal recurring
accruals) have been made to provide a fair presentation.

6. RECAPITALIZATION

     On February 13, 1998, the Company's then majority stockholder, Toyo
Information Systems (TIS), relinquished all of its shares of Preferred Stock
Series A and B and notes payable, together with accrued interest thereon of
$4,837,926, for 3,200,000 shares of Preferred Stock Series 1. In connection with
this transaction (Recapitalization), the Company surrendered certain rights
under an existing license agreement with TIS. Prior to the Recapitalization, the
Company and TIS were parties to a license agreement (License Agreement) whereby
TIS was obligated to pay the Company a 30% royalty on certain sales in Japan of
its product containing the Company's proprietary technology. Contemporaneous
with the Recapitalization, the Company waived its rights to future royalties
under this License Agreement for up to ten years. The Company obtained an
independent appraisal of the value of the royalty waiver to determine the amount
attributable to the transfer of the license to TIS as a return of capital in
conjunction with the relinquishment of previously outstanding Preferred Stock
and notes payable. The value of the royalty waiver of $1,800,000 has been
recognized as a deferred credit on the balance sheet, with a corresponding
reduction to stockholders' equity. The deferred credit will be recognized in
income as TIS completes sales

of the Company's products in Japan for which a royalty would otherwise have been
payable. In the event the deferred credit is not fully recognized in income upon
the expiration of the License Agreement, the remaining balance will be credited
to additional paid-in capital.

7. PREFERRED STOCK

     The Company's authorized capital includes Convertible Preferred Stock,
Series 1 Participating (Series 1) and Series 2 Non-Participating (Series 2).
Series 1 and 2 have been designated and issued. At September 30, 1999, Series 1
and 2 Preferred Stock represented all of the issued Convertible Preferred Stock.

CONVERSION

     Each share of Series 1 and 2 Preferred Stock is convertible at the
stockholder's option. Each share of Series 1 and 2 Preferred Stock may be
converted into shares of Common Stock at an initial conversion prices of $1.00
and $2.50 per share, respectively, as adjusted from time to time by a conversion
factor (the Conversion Price).

     The shares will automatically convert into Common Stock at the then
effective Conversion Price upon the closing of a public offering of the
Company's Common Stock pursuant to an effective registration statement under the
Securities Act of 1933.

DIVIDENDS

     The holders of Series 1 and 2 Preferred Stock shall be entitled to receive,
when and if declared by the Board of Directors of the Company, dividends in the
same amount per share as would be payable on the number of shares of Common
Stock into which the Preferred Stock is then convertible, payable in preference
and priority to any payment of any cash dividend on Common Stock or any other
class of stock or series thereof.

VOTING

     Series 1 and Series 2 Preferred shares are entitled to a number of votes on
any matter submitted to the stockholders of the Company equal to the number of
shares of Common Stock into which they are convertible.

LIQUIDATION

     Upon any liquidation of the Company, the holder of each share of Series 1
Preferred Stock shall be first entitled, before any distribution or payment is
made to holders of Series 2 Preferred Stock and Common Stock, to be paid $1.00
per share plus any declared and unpaid dividends thereon. Additionally, after
such payments have been made in full to the holders of Series 1 Preferred Stock,
Series 2 Preferred Stock shall be entitled, before any distribution or payment
is made to holders of Common Stock, to be paid $2.50 per share plus any declared
and unpaid dividends thereon. After payments have been made in full, such
holders of Series 1 Preferred Stock will participate with the holders of Common
Stock in the distribution of any remaining assets not to exceed $4.00 per share,
adjusted appropriately for stock splits, stock dividends and the like.

WARRANTS

     During 1998, in connection with the issuance of Series 1 Convertible
Preferred Stock, the Company issued warrants to purchase 3,075,006 shares of the
Company's Common Stock. The warrants are not

price of $2.50. The exercise period is ten years or five years from the
effective date of the Company's initial public offering, whichever is earlier.
As of September 30, 1999, none of the warrants issued had been exercised. The
fair market value of these warrants is being amortized over the term of the
Lease Agreement.

8. STOCK OPTION PLANS

     On December 27, 1990 (as amended on August 20, 1998), the Company
established a Stock Option Plan (the Plan) whereby 2,100,766 shares of Common

     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of January 17, 2000 by and among OnDisplay, Inc., a Delaware
corporation ("Parent"), ObiOne Acquisition Corporation, a Delaware corporation
and a wholly-owned subsidiary of Parent ("Sub"), Oberon Software Incorporated, a
Massachusetts corporation (the "Company"), and with respect to Article VII and
Article IX hereof, Joseph Chappell (the "Stockholder Representative").

                                    RECITALS

     A. The Boards of Directors of each of Parent, Sub and the Company believe
it is in the best interests of each company and its respective stockholders that
Parent acquire the Company through the statutory merger of Sub with and into the
Company (the "Merger") and, in furtherance thereof, have approved the Merger.

     B. Pursuant to the Merger, among other things, (i) all of the issued and
outstanding Company Capital Stock shall be converted into the right to receive
the consideration set forth herein, and (ii) the stock option plans of the
Company and all issued and outstanding options to purchase capital stock of the
Company shall be assumed by the Surviving Corporation with shares of common
stock of Parent being substituted for the shares of capital stock of the Company
issuable thereunder.

     C. A portion of the consideration otherwise payable by Parent in connection
with the Merger in respect of outstanding Company Capital Stock shall be placed
in escrow by Parent as security for the indemnification obligations set forth in
this Agreement.

     D. Concurrent with the execution and delivery of this Agreement, as a
material inducement to Parent and Sub to enter into this Agreement, certain
stockholders of the Company are entering into Voting Agreements, in the form
attached hereto as Exhibit A (the "Voting Agreements"), with Parent, certain
employees of the Company are entering into Non-Competition Agreements in the
form attached hereto as Exhibit B, and certain other employees of the Company
are entering into Non-Competition Agreements in the form attached hereto as
Exhibit B-1 (together with Exhibit B, the "Non-Competition Agreements").

     E. Concurrent with the execution and delivery of this Agreement, as a
material inducement to the Company to enter into this Agreement, certain
stockholders of Parent are entering Parent Voting Agreements in the form
attached hereto as Exhibit C (the "Parent Voting Agreements").

     F. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended.

     NOW, THEREFORE, in consideration of the mutual agreements, covenants and
other promises set forth herein, the mutual benefits to be gained by the
performance thereof, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged and accepted, the parties
hereby agree as follows:

                                   ARTICLE I

                                   THE MERGER

     1.1  The Merger. At the Effective Time (as defined in Section 1.2 hereof)
and subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the General Corporation Law of the Commonwealth of
Massachusetts ("Massachusetts Law"), Sub shall be merged with and into the
Company, the separate corporate existence of Sub shall cease and the Company
shall continue as the surviving corporation and as a wholly-owned subsidiary of
Parent. The surviving corporation after the Merger is sometimes referred to
hereinafter as the "Surviving Corporation."

                                       A-5
<PAGE>   162

     1.2  Effective Time. Unless this Agreement is earlier terminated pursuant
to Section 8.1 hereof, the closing of the Merger (the "Closing") will take place
as promptly as practicable after the execution and delivery hereof by the
parties hereto, but no later than five (5) business days following satisfaction
or waiver of the conditions set forth in Article VI hereof, at the offices of
Wilson Sonsini Goodrich & Rosati, Professional Corporation, Spear Street Tower,
One Market, San Francisco, California, 94105, unless another time and/or place
is mutually agreed upon in writing by Parent and the Company. The date upon
which the Closing actually occurs shall be referred to herein as the "Closing
Date." On the Closing Date, the parties hereto shall cause the Merger to be
consummated by filing Articles of Merger (or like instrument) with the Secretary
of the Commonwealth of Massachusetts (the "Articles of Merger"), in accordance
with the applicable provisions of Massachusetts Law (the time of acceptance by
the Secretary of the Commonwealth of Massachusetts of such filing, or such later
time as may be specified in the Articles of Merger, shall be referred to herein
as the "Effective Time").

     1.3  Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in the applicable provisions of Massachusetts Law. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, except as otherwise agreed to pursuant to the terms of this Agreement, all
the property, rights, privileges, powers and franchises of the Company and Sub
shall vest in the Surviving Corporation, and all debts, liabilities and duties
of the Company and Sub shall become the debts, liabilities and duties of the
Surviving Corporation.

     1.4  Certificate of Incorporation and Bylaws.

     (a) Unless otherwise determined by Parent prior to the Effective Time, the
articles of organization of Sub, as in effect immediately prior to the Effective
Time, shall be the articles of organization of the Surviving Corporation at the
Effective Time until thereafter amended in accordance with Massachusetts Law and
as provided in such articles of organization; provided, however, that at the
Effective Time, Article I of the Articles of Organization of the Surviving
Corporation shall be amended and restated in its entirety to read as follows:
"The name of the corporation is Oberon Software Incorporated."

     (b) Unless otherwise determined by Parent prior to the Effective Time, the
bylaws of Sub immediately prior to the Effective Time, shall be the bylaws of
the Surviving Corporation at the Effective Time until thereafter amended in
accordance with Massachusetts Law and as provided in the articles of
organization of the Surviving Corporation and such bylaws.

     1.5  Directors and Officers.

     (a) Unless otherwise determined by Parent prior to the Effective Time, the
directors of Sub immediately prior to the Effective Time shall be the directors
of the Surviving Corporation immediately after the Effective Time, each to hold
the office of a director of the Surviving Corporation in accordance with the
provisions of Massachusetts Law and the articles of organization and bylaws of
the Surviving Corporation until their successors are duly elected and qualified.

     (b) Unless otherwise determined by Parent prior to the Effective Time or as
otherwise provided herein, the officers of the Company immediately prior to the
Effective Time shall be the officers of the Surviving Corporation immediately
after the Effective Time, each to hold office in accordance with the provisions
of the bylaws of the Surviving Corporation.

     1.6  Effect of Merger on the Capital Stock of the Constituent
Corporations.

     (a) Conversion of Company Capital Stock. At the Effective Time, each
outstanding share of Company Common Stock and Preferred (collectively, the
"Company Capital Stock"), upon the terms and subject to the conditions set forth
below and throughout this Agreement, will be canceled and extinguished and be
converted automatically into the right to receive such number of shares of
Parent Common Stock equal to the Exchange Ratio, upon the terms and subject to
conditions set forth in this Section 1.6 and throughout this Agreement,
including, without limitation, the escrow provisions set forth in Article VII
hereof.

                                       A-6
<PAGE>   163

     (b) Assumption of Company Plans and Options. As soon as practicable
following the Closing but effective as of the Effective Time, the Company's 1990
and 1998 Stock Incentive Plans (collectively, the "Plan") and each Company
Option shall be assumed by the Surviving Corporation. Each Company Option so
assumed by Parent pursuant to this Section 1.6(b) shall continue to have, and be
subject to, the same terms and conditions (including vesting terms) set forth in
the Plan, and the option agreements relating thereto, as in effect immediately
prior to the Effective Time, except that (A) such assumed Company Option will be
exercisable 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 Exchange Ratio, rounded down to the nearest whole number of
shares of Parent Common Stock, and (B) the per share exercise price for the
shares of Parent Common Stock issuable upon exercise of such assumed Company
Option shall be equal to the quotient obtained by dividing the exercise price
per share of Company Common Stock at which such assumed Company Option was
exercisable immediately prior to the Closing Date by the Exchange Ratio, rounded
up to the nearest whole cent. Parent will issue to each holder of an outstanding
Company Stock Option a notice describing the foregoing assumption of such
Company Stock Option by Parent. It is intended that Company Stock Options
assumed by the Surviving Corporation shall qualify following the Effective Time
as incentive stock options as defined in Section 422 of the Code to the extent
Company Stock Options qualified as incentive stock options immediately prior to
the Effective Time and the provisions of this Section 1.6(b) shall be applied
consistent with such intent.

     (c) Withholding Taxes. Any amounts payable to any Stockholder pursuant to
this Section 1.6 shall be subject to, and reduced by an amount equal to, the
amount of any state, federal and foreign withholding taxes incurred (and not
previously paid by or on behalf of such stockholder of the Company) in
connection with the acquisition of Company Common Stock or Preferred upon the
exercise of Company Options, upon the lapsing of repurchase rights in respect of
shares of Company Common Stock, or upon payment of a bonus in the form of
Company Common Stock, if any, to such stockholder.

     (d) Stockholder Loans. In the event that any Stockholder has outstanding
loans from the Company as of the Effective Time, the consideration payable to
such stockholder pursuant to this Section 1.6 shall be reduced by an amount
equal to the outstanding principal plus accrued interest of such stockholder's
loans as of the Effective Time.

     (e) 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.

     (f) Fractional Shares. No fraction of a share of Parent Common Stock will
be issued, but in lieu thereof, each holder of shares of Company Common Stock
and Preferred (including Company Common Stock issuable upon exercise of
outstanding Company Options at the Effective Time) who would otherwise be
entitled to a fraction of a share of Parent Common Stock (after aggregating all
fractional shares of Parent Common Stock to be received by such holder) shall be
entitled to receive from Parent an amount of cash (rounded to the nearest whole
cent) equal to the product of (i) such fraction, multiplied by (ii) the Trading
Price.

     (g) Sufficient Reserved Shares. Parent will reserve sufficient shares of
Parent Common Stock for issuance under this Section 1.6.

     (h) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted to
reflect appropriately the effect of any stock split, reverse stock split, stock
dividend (including any dividend or distribution of securities convertible into
Parent Common Stock or Company Common Stock or Preferred), reorganization,
recapitalization, reclassification or other like change with respect to Parent
Common Stock or Company Common Stock or Preferred occurring on or after the date
hereof and prior to the Effective Time.

     1.7  Surrender of Certificates.

     (a) Exchange Agent. The Corporate Secretary of Parent shall serve as the
exchange agent (the "Exchange Agent") for the Merger.

     (b) Parent to Provide Parent Common Stock. Promptly after the Effective
Time, Parent shall make available to the Exchange Agent for exchange in
accordance with this Article I the shares of Parent Common Stock issuable
pursuant to Section 1.6 in exchange for outstanding shares of Company Common
Stock and Preferred; provided that, on behalf of the Stockholders, Parent shall
deposit into the Escrow Fund (as defined in Section 7.3(a)) a number of shares
of Parent Common Stock equal to the Escrow Amount out of the aggregate number of
shares of Parent Common Stock otherwise issuable to the Stockholders pursuant to
Section 1.6. Each Stockholder shall be deemed to have contributed his or her Pro
Rata Portion of the Escrow Amount to the Escrow Fund (as defined in Section
7.3(a) below).

     (c) Exchange Procedures. On or promptly after the Effective Time, the
Stockholders will surrender the certificates representing their Company Common
Stock and Preferred (the "Stock Certificates") to the Exchange Agent for
cancellation together with a letter of transmittal in such form and having such
provisions that Parent may reasonably request. Upon surrender of a Stock
Certificate for cancellation to the Exchange Agent, or 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,
subject to the terms of Section 1.7(f) hereof, the holder of such Stock
Certificate shall be entitled to receive from the Exchange Agent in exchange
therefor a certificate representing the number of whole shares of Parent Common
Stock (less the number of shares of Parent Common Stock to be deposited in the
Escrow Fund on such holder's behalf pursuant to Section 1.7(b) above and Article
VII hereof), and the Stock Certificate so surrendered shall be canceled. Until
so surrendered, each outstanding Stock Certificate will be deemed from and after
the Effective Time, and for all corporate purposes, to evidence only the
ownership of the number of full shares of Parent Common Stock into which such
shares of Company Common Stock and Preferred shall have been so converted.

     (d) Dissenting Stockholders.

          (i) Notwithstanding any provision of this Agreement to the contrary,
     any shares of Company Common Stock or Preferred held by a holder who,
     immediately prior to the Effective Time, acting in accordance with Sections
     86 to 98 of Chapter 156B of the Massachusetts Law, (i) prior to the special
     meeting at which the Stockholders vote to approve the Merger (the "Special
     Meeting") has delivered to the Company written notice of his intention to
     demand payment for his shares of Company Common Stock or Preferred if the
     Merger is effectuated and (ii) has not voted in favor of the Merger, shall
     not have his shares of Company Common Stock or Preferred converted into a
     right to receive shares of Parent Common Stock. If, however, after the
     Effective Time such holder withdraws or loses his right to demand payment
     for his Company Common Stock or Preferred, such Company Common Stock or
     Preferred shall be treated as if it had been converted as of the Effective
     Time and (i) as of the occurrence of such event, such holder's Company
     Common Stock or Preferred shall treated as if it had been converted as of
     the Effective Time into the right to receive that number of shares of
     Parent Common Stock as is set forth Section 1.6 hereof, and (ii) promptly
     following the occurrence of such event, the Parent shall deliver to the
     Exchange Agent a certificate representing 90% of the shares of Parent
     Common Stock to which such holder is entitled pursuant to Section 1.6(a)
     and shall deliver to the Escrow Agent a certificate representing the
     remaining 10% of the shares of Parent Common Stock to which such holder is
     entitled pursuant to Section 1.6(a) (which shares shall be considered part
     of the Escrow Fund for all purposes of this Agreement).

          (ii) The Company shall give the Parent (i) prompt notice of any
     written demands for payment of any Company Common Stock or Preferred,
     withdrawals of such demands, and any other instruments that relate to such
     demands received by the Company and (ii) the opportunity to direct all
     negotiations and proceedings with respect to demands for appraisal under
     the Massachusetts Law. The Company shall not, except with the prior written
     consent of Parent, make any payment with

                                       A-8
<PAGE>   165

     respect to any demands for appraisal of Company Common Stock or Preferred
     or offer to settle or settle any such demands.

     (e) Distributions With Respect to Unexchanged Shares. No dividends or other
distributions declared or made after the Effective Time with respect to Parent
Common Stock with a record date after the Effective Time will be paid to the
holder of any unsurrendered Stock Certificate with respect to the shares of
Parent Common Stock represented thereby until the holder of record of such Stock
Certificate shall surrender such Stock Certificate. Subject to applicable law,
following surrender of any such Stock Certificate, there shall be paid to the
record holder of the certificates representing whole shares of Parent Common
Stock issued in exchange therefor, without interest, at the time of such
surrender, the amount of dividends or other distributions with a record date
after the Effective Time theretofore paid with respect to such whole shares of
Parent Common Stock.

     (f) Transfers of Ownership. If any certificate for shares of Parent Common
Stock is to be issued in a name other than that in which the certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance and/or delivery thereof that the certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
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 a certificate
for shares of Parent Common Stock in any name other than that of the registered
holder of the certificate surrendered, or established to the satisfaction of
Parent or any agent designated by it that such tax has been paid or is not
payable.

     (g) No Liability. Notwithstanding anything to the contrary in this Section
1.7 hereof, neither the Exchange Agent, the Surviving Corporation nor any party
hereto shall be liable to a holder of shares of Company Common Stock or
Preferred for any amount properly paid to a public official pursuant to any
applicable abandoned property, escheat or similar law.

     1.8  No Further Ownership Rights in Company Common Stock. The shares of
Parent Common Stock paid in respect of the surrender for exchange of shares of
Company Common Stock and Preferred in accordance with the terms hereof, shall be
deemed to be full satisfaction of all rights pertaining to such shares of
Company Common Stock and Preferred, and there shall be no further registration
of transfers on the records of the Surviving Corporation of shares of Company
Common Stock and Preferred which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Stock Certificates are presented
to the Surviving Corporation for any reason, they shall be canceled and
exchanged as provided in this Article I.

     1.9  Lost, Stolen or Destroyed Certificates. In the event any certificates
evidencing shares of Company Common Stock/Preferred 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 amount, if any, as may be required pursuant to Section 1.6
hereof; provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the stockholder who is the owner of
such lost, stolen or destroyed certificates to deliver a bond in such amount 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.

disclosed to Parent in writing, or as required by this Agreement), or to enter
into any Company Employee Plan, International Employee Plan or Employment
Agreement.

     (c) Documents. The Company has made available to Parent (i) correct and
complete copies of all documents embodying each Company Employee Plan,
International Employee Plan, and each Employment Agreement including, without

     (d) Employee Plan Compliance. The Company has performed in all material
respects all obligations required to be performed by it under, is not in
material default or violation of, and has no Knowledge of any default or
violation by any other party to each Company Employee Plan, and each Company
Employee Plan has been established and maintained in all material respects in
accordance with its terms and in compliance with all applicable laws, statutes,
orders, rules and regulations, including but not limited to ERISA or the Code.
Each Company Employee Plan intended to qualify under Section 401(a) of the Code
and each trust intended to qualify under Section 501(a) of the Code has either
received a favorable determination, opinion, notification or advisory letter
from the IRS with respect to each such Company Employee Plan as to its qualified
status under the Code, including all amendments to the Code effected by the Tax
Reform Act of 1986 and subsequent legislation, or has remaining a period of time
under applicable Treasury regulations or IRS pronouncements in which to apply
for such a letter and make any amendments necessary to obtain a favorable
determination as to the qualified status of each such Company Employee Plan. No
"prohibited transaction," within the meaning of Section 4975 of the Code or
Sections 406 and 407 of ERISA, and not otherwise exempt under Section 4975 of
the Code or Section 408 of ERISA (or any administrative class exemption issued
thereunder), has occurred with respect to any Company Employee Plan which would
result in material liability to the Company. There are no actions, suits or
claims pending, or to the Knowledge of the Company and the Principal
Stockholders threatened or reasonably anticipated (other than routine claims for
benefits) against any Company Employee Plan or against the assets of any Company
Employee Plan that could reasonably be expected to result in material liability.
Each Company Employee Plan (other than any stock option plan) can be amended,
terminated or otherwise discontinued after the Effective Time in accordance with
its

                                      A-22
<PAGE>   179

terms, without liability to Parent, the Company or any Affiliate (other than
ordinary administration expenses and already accrued benefits). There are no
audits, inquiries or proceedings pending or to the Knowledge of the Company and
the Principal Stockholders or any Affiliates, threatened by the IRS or DOL with
respect to any Company Employee Plan. Neither the Company nor any Affiliate is
subject to any material penalty or tax with respect to any Company Employee Plan
under Section 502(i) of ERISA or Sections 4975 through 4980 of the Code.

     (e) No Pension Plan. Neither the Company nor any other Affiliate has ever
maintained, established, sponsored, participated in, or contributed to, any (i)
Pension Plan subject to Title IV of ERISA or Section 412 of the Code

     (f) Collectively Bargained, Multiemployer and Multiple Employer Plans. At
no time has the Company or any Affiliate contributed to or been obligated to
contribute to any Multiemployer Plan. Neither the Company, nor any Affiliate has
at any time ever maintained, established, sponsored, participated in, or
contributed to any multiple employer plan, or to any plan described in Section
413 of the Code.

     (g) No Post-Employment Obligations. No Company Employee Plan provides, or
reflects or represents any liability to provide, retiree life insurance, retiree
health or other retiree employee welfare benefits to any person for any reason,
except as may be required by COBRA or other applicable statute, and the Company
has never represented, promised or contracted (whether in oral or written form)
to any Employee (either individually or to Employees as a group) or any other
person that such Employee(s) or other person would be provided with retiree life
insurance, retiree health or other retiree employee welfare benefit, except to
the extent required by statute.

     (g) Health Care Compliance. Neither the Company nor any Affiliate has,
prior to the Effective Time and in any material respect, violated any of the
health care continuation requirements of COBRA, the requirements of FMLA, the
requirements of the Health Insurance Portability and Accountability Act of 1996,
the requirements of the Women's Health and Cancer Rights Act of 1998, the
requirements of the Newborns' and Mothers' Health Protection Act of 1996, or any
amendment to each such act, or any similar provisions of state law applicable to
its Employees.

     (h) Effect of Transaction. The execution of this Agreement and the
consummation of the transactions contemplated hereby will not (either alone or
upon the occurrence of any additional or subsequent events) constitute an event
under any Company Employee Plan, Employment Agreement, trust or loan that will
or may result in any payment (whether of severance pay or otherwise),
acceleration, forgiveness of indebtedness, vesting, distribution, increase in
benefits or obligation to fund benefits with respect to any Employee, except as
expressly required by this Agreement.

     (i) Employment Matters. The Company: (i) is in compliance in all material
respects with all applicable foreign, federal, state and local laws, rules and
regulations respecting employment, employment practices, terms and conditions of
employment and wages and hours, in each case, with respect to Employees,
including all applicable laws of foreign jurisdictions where the Company has
Employees; (ii) has withheld and reported all amounts required by law or by
agreement to be withheld and reported with respect to wages, salaries and other

liable for any payment to any trust or other fund governed by or maintained by
or on behalf of any governmental authority, with respect to unemployment
compensation benefits, social security or other benefits or obligations for
Employees (other than routine payments to be made in the normal course of
business and consistent with past practice). There are no pending, or to the
Knowledge of the Company threatened, claims or actions against the Company under
any worker's compensation policy or long-term disability policy.

     (j) International Employee Plan. Each International Employee Plan has been
established, maintained and administered in compliance with its terms and

                                      A-23
<PAGE>   180

Furthermore, no International Employee Plan has unfunded liabilities, that as of
the Effective Time, will not be offset by insurance or fully accrued. Except as
required by law, no condition exists that would prevent the Company or Parent
from terminating or amending any International Employee Plan at any time for any
reason without liability to the Company, the Parent or its Affiliates (other
than ordinary administration expenses or routine claims for benefits).

     2.21  Insurance. The Company maintains insurance policies and fidelity
bonds covering the assets, business, equipment, properties, operations,
employees, contract workers, officers and directors of the Company or any
Affiliate. There is no claim by the Company or any Affiliate pending under any
of such policies or bonds as to which coverage has been questioned, denied or
disputed by the underwriters of such policies or bonds. All premiums due and
payable under all such policies and bonds have been paid, and the Company and
its Affiliates are otherwise in material compliance with the terms of such
policies and bonds (or other policies and bonds providing substantially similar
insurance coverage). The Company has no Knowledge of threatened termination of,
or premium increase with respect to, any of such policies.

     2.22  Compliance with Laws. The Company has complied with and is not in
violation of any foreign, federal, state or local statute, law or regulation
except when the failure to comply would not have a Company Material Adverse
Effect. The Company has not received any notices of violation with respect to
any such statute, law or regulation.

     2.23  Representations Complete. Neither any of the representations or
warranties made by the Company (as modified by the Company Disclosure Schedule)
in this Agreement, contains or will contain at the Effective Time, any untrue
statement of a material fact, or omits or will omit at the Effective Time to
state any material fact necessary in order to make the statements contained

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                               OF PARENT AND SUB

     Parent and Sub hereby represent and warrant to the Company, subject to such
exceptions as are specifically disclosed in the disclosure letter (referencing
the appropriate section and paragraph numbers) supplied by the Parent and Sub to
the Company (the "Parent Disclosure Schedule") and dated as of the date hereof,
that on the date hereof and as of the Effective Time as though made at the
Effective Time as follows:

     3.1  Organization, Standing and Power. Parent is a corporation duly
organized, validly existing and in good standing under the laws of Delaware. Sub
is a corporation duly organized, validly existing and in good standing under the
laws of Delaware. Each of Parent and Sub has the corporate power to own its
properties and to carry on its business as now being conducted and is duly
qualified or licensed to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or licensed would have a
Parent Material Adverse Effect, provided that a drop in the Parent's stock price
shall not constitute such a material adverse effect.

     3.2  Authority. Each of Parent and Sub has all requisite corporate power
and authority to enter into this Agreement and any Related Agreements to which
it is a party and to consummate the transactions contemplated hereby and
thereby. The execution and delivery of this Agreement and any Related Agreements
to which it is a party and the consummation of the transactions contemplated
hereby and thereby have been duly authorized by all necessary corporate action
on the part of Parent and Sub, subject only to stockholder approval. This
Agreement and any Related Agreements to which Parent and Sub are
                                      A-24
<PAGE>   181

parties have been duly executed and delivered by Parent and Sub and constitute
the valid and binding obligations of Parent and Sub, enforceable in accordance
with their terms, except as such enforceability may be limited by principles of
public policy and subject to the laws of general application relating to
bankruptcy, insolvency and the relief of debtors and rules of law governing
specific performance, injunctive relief or other equitable remedies.

     3.3  Consents. No consent, waiver, approval, order or authorization of, or
registration, declaration or filing with, any Governmental Entity, or any third
party is required by or with respect to Parent or Sub in connection with the
execution and delivery of this Agreement and any Related Agreements to which
Parent or Sub is a party or the consummation of the transactions contemplated
hereby and thereby, except for (i) such consents, waivers, approvals, orders,
authorizations, registrations, declarations and filings as may be required under
applicable securities laws, (ii) such consents, waivers, approvals, orders,
authorizations, registrations, declarations and filings which, if not obtained
or made, would not have a Parent Material Adverse Effect, and (iii) the filing
of the Merger Agreement with the Secretary of the Commonwealth of Massachusetts.

     3.4  Parent Common Stock. The Parent Common Stock which constitutes the
Merger Shares has been duly authorized, and upon consummation of the
transactions contemplated by this Agreement, will be validly issued, fully paid
and nonassessable.

     3.5  Intellectual Property. To Parent's knowledge, the reproduction,
manufacturing, distribution, licensing, sublicensing, and/or sale of Parent's
products and services does not infringe on any patent, design right, trademark,
trade name, service mark, trade dress, Internet domain name, copyright,
database, trade secret, know-how, of any person, anywhere in the world. No
claims, other than with respect to Parent's licensed intellectual property, (i)
challenging the validity, effectiveness or, ownership by Parent's of any Parent
intellectual property, or (ii) to the effect that the use, distribution,
licensing, sublicensing, and/or sale or any of Parent's products or services,
infringes or will infringe on any intellectual property or other proprietary or
personal right of any person, have been asserted or, to the knowledge of Parent,
are threatened by any person, nor are there, to Parent's knowledge, any valid
grounds for any bona fide claim of any such kind. To Parent's knowledge, no
third party is materially infringing Parent owned intellectual property.

     3.6  Litigation. There is no material action, suit, claim or proceeding of
any nature pending, or to the Knowledge of Parent threatened, against Parent,
its properties (tangible or intangible) or any of its officers or directors.
There is no investigation or other proceeding pending or to the Knowledge of
Parent threatened, against Parent, any of its properties (tangible or
intangible) or any of their officers or directors by or before any Governmental
Entity. No Governmental Entity has at any time challenged or questioned the
legal right of Parent to develop or distribute any of its products.

     3.7  SEC Reports; Financial Statements. Parent has made available to
Company a correct and complete copy of each report, schedule, registration
statement and definitive proxy statement filed by Purchaser with the SEC on or
after September 30, 1999 (the "SEC Reports"), which are all the forms, reports
and documents required to be filed by Parent with the SEC since September 30,
1999. The Parent SEC Reports (A) were prepared in accordance with the
requirements of the Securities Act or the Exchange Act, as the case may be, and
(B) did not at the time they were filed (or if amended or superseded by a filing
prior to the date of this Agreement, then on the date of such filing) contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Since September 30, 1999, there has not occurred a Parent Material
Adverse Effect. Each set of consolidated financial statements (including, in
each case, any related notes thereto) contained in the Parent SEC Reports was
prepared in accordance with U.S. GAAP applied on a consistent basis throughout
the periods involved (except as may be indicated in the notes thereto or, in the
case of unaudited statements, do not contain footnotes as permitted by Form 10-Q
of the Exchange Act) and each fairly presents the consolidated financial
position of Parent and its subsidiaries at the respective dates thereof and the
consolidated results of its operations and cash flows for the periods indicated,
except that

                                      A-25
<PAGE>   182

the unaudited interim financial statements were or are subject to normal
adjustments which are not material in the aggregate.

     3.8  Representations Complete. Neither any of the representations or
warranties made by Parent (as modified by the Parent Disclosure Schedule) in
this Agreement contains or will contain at the Effective Time, any untrue
statement of a material fact, or omits or will omit at the Effective Time to
state any material fact necessary in order to make the statements contained
herein or therein, in the light of the circumstances under which made, not
misleading. The information furnished by Parent for inclusion in any documents
mailed, delivered or otherwise furnished to the stockholders of Parent in
connection with the solicitation of their consent to this Agreement and the
Merger, will not contain, at or prior to the Effective Time, any untrue
statement of a material fact and will not omit to state any material fact
necessary in order to make the statements made therein, in light of the
circumstances under which made, not misleading.

                                   ARTICLE IV

<PAGE>   191

     7.2  Indemnification. The Stockholders jointly and severally (severally in
the case of claims and Losses (or portions thereof), as defined below, after
exhaustion of the Escrow Fund) agree to indemnify and hold Parent and its
officers, directors and affiliates, including the Company after the Closing (the
"Indemnified Parties"), harmless against all claims, losses, liabilities,
damages, deficiencies, costs and expenses, including reasonable attorneys' fees
and expenses of investigation and defense relating to such claim, loss,
liability, damage, deficiency, cost or expense (hereinafter individually a
"Loss" and collectively "Losses") incurred or suffered by the Indemnified
Parties, or any of them (including the Company after the Closing), directly or
indirectly, as a result of (i) any breach or inaccuracy of a representation or
warranty of the Company contained in this Agreement or any certificate or
instrument delivered pursuant to this Agreement, (ii) any failure by the Company
to perform or comply with any covenant applicable to them contained in this
Agreement, and (iii) the failure of Estimated Third Party Expenses to equal or
exceed Third Party Expenses. The Stockholders shall not have any right of
contribution from the Company with respect to any Loss claimed by an Indemnified
Party after the Effective Time.

     7.3  Escrow Arrangements.

     (a) Escrow Fund. As partial security for the indemnity provided for in
Section 7.2 hereof and by virtue of this Agreement, the Stockholders will be
deemed to have received and deposited with the Escrow Agent the Escrow Amount
without any act of any Stockholder. The Escrow Fund shall be available to
compensate the Indemnified Parties, or any of them, for any claims by such
Indemnified Parties for any Losses suffered or incurred by them; provided,
however, that if the Escrow Period (as defined below) has terminated, and a
claim for Losses is made with respect to fraud, the claim shall be made directly
against the Stockholders. Within three days after the Closing, the Escrow
Amount, without any act of the Stockholders, will be deposited with the Escrow
Agent hereunder, or another institution acceptable to Parent and the Stockholder
Representative (as defined in Section 7.4 hereof), such deposit of the Escrow
Amount 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 Closing, and such later execution, if so
executed after the date hereof, shall not affect the binding nature of this
Agreement as of the date hereof between the other signatories hereto. Nothing
herein shall limit the liability of the Company for any breach or inaccuracy of
any representation, warranty or covenant contained in this Agreement if the
Merger does not close. Parent may not receive any proceeds from the Escrow Fund
unless and until one or more Officer's Certificates (as defined in Section
7.3(d) hereof) identifying Losses in excess of $1,000,000 in the aggregate (the
"Basket Amount") has or have been delivered to the Escrow Agent as provided in
Section 7.3(d) hereof, in which case Parent shall be entitled to recover all
Losses so identified in excess of the Basket Amount. Notwithstanding the
foregoing, Parent shall be entitled to receive payments out of the Escrow Fund
for, and the Basket Amount shall not apply as a threshold to, any and all claims
or payments made with respect to Third Party Expenses in excess of $750,000.

     (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., P.S.T., on
January 18, 2001 (the "Escrow Termination Period"); provided, however, that the
Escrow Period shall not terminate with respect to any amount which, in the
reasonable good faith judgment of Parent, subject to the objection of the
Stockholder Representative and the subsequent arbitration of the matter in the
manner provided in Section 7.3(f) hereof, is necessary to satisfy any then
pending and unsatisfied claims specified in any Officer's Certificate delivered
to the Escrow Agent prior to the thirtieth (30th) calendar day following the
termination of the Escrow Period with respect to facts and circumstances
existing prior to the termination of such Escrow Period. As soon as all such
claims have been resolved, the Escrow Agent shall deliver to the Stockholders
the remaining portion of the Escrow Fund, if any, not required to satisfy such
claims (the "Remaining Portion"). Deliveries of the Escrow Amount out of the
Escrow Fund to the Stockholders pursuant to this Section 7.3(b) shall be made in
proportion to their respective Pro Rata Portions of the Escrow Fund.

Substitution of Cash.

          (i) The Escrow Agent shall hold and safeguard the Escrow Fund during

     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 shall not be
     added to the Escrow Fund but shall be distributed to the record holders
     thereof.

          (iii) Each Stockholder shall have voting rights with respect to the
     shares of Parent Common Stock contributed to the Escrow Fund by such
     Stockholder (and on any voting securities added to the Escrow Fund in
     respect of such shares of Parent Common Stock).

          (iv) Subject to Section 1.11, the Stockholder Representative may
     effect a sale of any or all of the shares comprising the Escrow Fund by
     written direction given to the Escrow Agent provided that (i) the net
     proceeds per share are at least equal to the Trading Price and (ii) the net
     proceeds equal to the Trading Price multiplied by the number of shares of
     Parent Common Stock so sold (the "Equivalent Net Proceeds") are retained in
     the Escrow Fund and are held at the election of the Stockholder
     Representative in an interest-bearing or non-interest bearing demand
     deposit account on behalf of the Stockholders. The Equivalent Net Proceeds
     from any such disposition and any interest accruing thereon shall be
     allocated among the Stockholders in accordance with their Pro Rata Portions
     of the Escrow Fund. Any net proceeds in excess of the Equivalent Net
     Proceeds shall be distributed to the Stockholders in accordance with their
     Pro Rata Portions of the Escrow Fund. This sale will occur at the written
     direction of the Stockholder Representative.

          (v) In connection with the release to Parent of any shares in the
     Escrow Fund as a result of Losses incurred by Parent under the Merger
     Agreement, a Stockholder shall be permitted to deposit cash in escrow equal
     to the Trading Price times that number of shares in the Escrow Fund held on
     behalf of such Stockholder which are to be delivered to Parent as Losses
     (the "Cash Out Amount") and to obtain the release of such shares in the
     Escrow Fund held on behalf of such Stockholder (the "Cash Out Shares")
     equal to the amount of cash so deposited divided by the Trading Price. The
     Cash Out Amount shall be in the form of a cashier's check payable to the
     Escrow Agent. Parent shall provide the Escrow Agent with such instructions
     as may be required to cause the release of any shares to a Stockholder
     paying the Cash Out Amount.

     (d) Claims for Indemnification.

          (i) Upon receipt by the Escrow Agent at any time on or before the
     thirtieth (30th) day following the last day of the Escrow Period of an
     Officer's Certificate (as defined below) and, subject to the provisions of
     Section 7.3(e) and Section 7.5 hereof, the Escrow Agent shall deliver to
     Parent out of the Escrow Fund, as promptly as practicable, Parent Common
     Stock (or cash in lien thereof) held in the Escrow Fund equal to Losses
     specified in the Officer's Certificate. For purposes hereof, "Officer's
     Certificate" shall mean a certificate signed by any officer of Parent: (a)
     stating that Parent has paid or incurred or properly accrued or reasonably
     anticipates that it will have to pay, incur or accrue Losses, and (b)
     specifying in reasonable detail the individual items of Losses included in
     the amount so stated, the date each such item was paid, incurred or
     properly accrued, or the basis for such anticipated liability, and the
     nature of the misrepresentation, breach of warranty or covenant to which
     such item is related.

          (ii) For the purposes of determining the number of shares of Parent
     Common Stock or cash in lieu of such shares to be delivered to Parent out
     of the Escrow Fund as indemnity pursuant to
                                      A-36
<PAGE>   193

     Section 7.2 hereof, the shares of Parent Common Stock shall be valued at
     the Trading Price and any cash paid in lieu of such shares shall be
     calculated accordingly.

          (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 Stockholder Representative, 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 7.3(d) hereof unless and
     until the Escrow Agent shall have received written authorization from the
     Stockholder Representative to make such delivery. After the expiration of
     such thirty (30) day period, the Escrow Agent shall make delivery of the
     Parent Common Stock (or cash in lieu thereof) from the Escrow Fund in
     accordance with Section 7.3(d) hereof; provided, however, that no such
     payment or delivery may be made if the Stockholder Representative 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.

     (f) Resolution of Conflicts; Arbitration.

          (i) In case the Stockholder Representative shall object in writing to
     any claim or claims made in any Officer's Certificate to recover Losses
     from the Escrow Fund within thirty (30) days after delivery of such
     Officer's Certificate, the Stockholder Representative 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 Stockholder Representative and
     Parent should so agree, a memorandum setting forth such agreement shall be
     prepared and signed by both parties and, in the case of a claim against the
     Escrow Fund, shall be furnished to the Escrow Agent. The Escrow Agent shall
     be entitled to rely on any such memorandum and distribute amounts 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 Stockholder Representative may demand arbitration of
     the matter unless the amount of the 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 Stockholder
     Representative. In the event that within forty-five (45) days after
     submission of any dispute to arbitration, Parent and the Stockholder
     Representative cannot mutually agree on one arbitrator, Parent and the
     Stockholder Representative 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 judgment 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 competent court of law or
     equity, should the arbitrators 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 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. 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 Francisco 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.

                                      A-37
<PAGE>   194

     (g) Third-Party Claims. In the event Parent becomes aware of a third-party
claim which Parent reasonably believes may result in a demand against the Escrow
Fund, Parent shall notify the Stockholder Representative of such claim, and the
Stockholder Representative shall be entitled on behalf of the Stockholders, at
its expense, to participate in, but not to determine or conduct, the defense of
such claim. Parent shall have the right in its sole discretion to conduct the
defense of and settle any such claim; provided, however, that except with the
consent of the Stockholder Representative, no settlement of any such claim with
third-party claimants shall be determinative of the amount of Losses relating to
such matter. In the event that the Stockholder Representative has consented in
writing to any such settlement, the Stockholders 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.

     (h) Escrow Agent's Duties. Prior to the Effective Time, Parent shall select
the Escrow Agent. Unless otherwise set forth in a separate escrow agreement with
the Escrow Agent:

          (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 Stockholder Representative, 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
     legal 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 this 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
     legal counsel in connection with performing the 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 the Escrow Amount and may wait for settlement of any
     such controversy by

                                      A-38
<PAGE>   195

     final appropriate legal proceedings or other means as, in the Escrow
     Agent's discretion, 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 the Escrow Amounts
     held in escrow, except all costs, 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
     those arising out of the negligence or willful misconduct of the Escrow
     Agent.

          (viii) The Escrow Agent may resign at any time upon giving at least
     thirty (30) days written notice to the Parent and the Stockholder
     Representative; provided, however, that no such resignation shall become
     effective until the appointment of a successor escrow agent which shall be
     accomplished as follows: Parent and the Stockholder Representative 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 Commonwealth of Massachusetts. 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.

     (i) 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.

     (j) Consequential Damages. In no event shall the Escrow Agent be liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Escrow Agent has been
advised of the likelihood of such loss or damage and regardless of the form of
action.

     (k) Successor Escrow Agents. Any corporation into which the Escrow Agent in
its individual capacity may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Escrow Agent in its individual capacity shall be a
party, or any corporation to which substantially all the corporate trust
business of the Escrow Agent in its individual capacity may be transferred,
shall be the Escrow Agent under this Escrow Agreement without further act.

     7.4  Stockholder Representative.

     (a) Each of the Stockholders hereby appoints Joseph Chappell its agent and
attorney-in-fact, as the Stockholder Representative for and on behalf of the
Stockholders, to give and receive notices and communications, to authorize
payment to Parent of shares of Parent Common Stock or cash from the Escrow Fund
in satisfaction of claims by Parent, to object to such payments, 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 other actions that are either (i) necessary or
appropriate in the judgment of the Stockholder Representative for the
accomplishment of the foregoing or (ii) specifically mandated by the terms of
this Agreement. Such agency may be changed by the Stockholders from time to time
upon not less than thirty (30) days prior written notice to Parent; provided,
however, that the Stockholder Representative may not be removed unless holders
of a two-thirds interest of the Escrow Fund agree to such removal and to the
identity of the substituted agent. Any vacancy in the position of Stockholder
Representative may be filled by the holders of a majority in interest of the
Escrow Fund. No bond shall be required of the Stockholder Representative, and
the Stockholder Representative shall not receive compensation for its services.
Notices or communications to or from the Stockholder Representative shall
constitute notice to or from the Stockholders.

     (b) The Stockholder Representative shall not be liable for any act done or
omitted hereunder as the Stockholder Representative while acting in good faith
and in the exercise of reasonable judgment. The Stockholders on whose behalf the
Escrow Amount was contributed to the Escrow Fund shall indemnify the Stockholder
Representative and hold the Stockholder Representative harmless against any
loss, liability or expense incurred without negligence or bad faith on the part
of the Stockholder Representative and arising out of or in connection with the
acceptance or administration of the Stockholder Representative's duties
hereunder, including the reasonable fees and expenses of any legal counsel
retained by the Stockholder Representative. After all claims for Losses by
Parent set forth in Officers' Certificates delivered to the Escrow Agent and the
Stockholder Representative has been satisfied, or reserved against, the
Stockholder Representative, with the consent of the majority in interest in the
Escrow Fund, may recover from the Escrow Fund at the end of the Escrow Period
payments not yet paid for any expenses incurred in connection with the
Stockholder Representative's representation hereby.

     (c) A decision, act, consent or instruction of the Stockholder
Representative, including but not limited to an amendment, extension or waiver
of this Agreement pursuant to Section 8.3 and Section 8.4 hereof, shall
constitute a decision of the Stockholders and shall be final, binding and
conclusive upon the Stockholders; and the Escrow Agent and Parent may rely upon
any such decision, act, consent or instruction of the Stockholder Representative
as being the decision, act, consent or instruction of the Stockholders. 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 Stockholder Representative.

     (d) Subject to Parent's prior claims for indemnification against the Escrow
Fund, the Stockholder Representative shall be entitled to receive payment for
its reasonable and documented expenses therefrom, prior to any payments to the
Stockholders.

     7.5  Maximum Payments; Remedy. Notwithstanding anything to the contrary set
forth in this Article VII or elsewhere in this Agreement, if the Merger is
consummated the maximum amount the Indemnified Parties may recover from the
Stockholders pursuant to the indemnity obligations set forth in Section 7.2
hereof shall be limited to an amount equal to each such Stockholder's Pro Rata
Portion of the Escrow Fund; provided however, that such limitation shall not
apply with respect to fraud claims by taxing authorities relating to Taxes or
liabilities related to, assessable upon, or based upon, the transactions
undertaken in connection with that certain Recapitalization, Stock Purchase and
Shareholders Agreement, dated as of February 13, 1998 among the Company, Toyo
Information Systems Co. Ltd. and the other parties thereto.

     rule, regulation or order enacted, promulgated or issued or deemed
     applicable to the Merger by any Governmental Entity, which would: (i)
     prohibit Parent's ownership or operation of any portion of the business of
     the Company or (ii) compel Parent or the Company to dispose of or hold
     separate all or any portion of the business or assets of the Company or

          (e) by Parent if there has been a breach of any representation,

the other party hereto, (ii) waive any inaccuracies in the representations and
warranties made to such party contained herein or in any document delivered

     9.4  Entire Agreement; Assignment. This Agreement, the exhibits hereto, the
Company Disclosure Schedule, the Confidential Disclosure Agreement, and the
documents and instruments and other agreements among the parties hereto
referenced herein: (i) constitute the entire agreement among the parties with
respect to the subject matter hereof and supersede all prior agreements and
understandings both written and oral, among the parties with respect to the
subject matter hereof, (ii) are not intended to confer upon any other person any
rights or remedies hereunder, and (iii) shall not be assigned by operation of
law or otherwise, except that Parent and Merger Sub may assign its rights and

party to the Agreement.

     9.5  Severability. In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction

continue in full force and effect and the application of such provision to other
persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the extent possible, the economic, business and other
purposes of such void or unenforceable provision.

     9.6  Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

     9.7  Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Massachusetts, regardless of the
laws that might otherwise govern under applicable principles of conflicts of
laws thereof. Each of the parties hereto irrevocably consents to the exclusive
jurisdiction and venue of any court within the Commonwealth of Massachusetts, in
connection with any matter based upon or arising out of this Agreement or the
matters contemplated herein, agrees that process may be served upon them in any
manner authorized by the laws of the Commonwealth of Massachusetts for such
persons and waives and covenants not to assert or plead any objection which they
might otherwise have to such jurisdiction, venue and such process.

     9.8  Rules of Construction. The parties hereto agree that they have been
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

     A. The Company, Merger Sub (as defined below) and Parent have entered into
an Agreement and Plan of Reorganization (the "Reorganization Agreement"), which
provides for the merger (the "Merger") of a wholly-owned subsidiary of Parent
("Merger Sub") with and into the Company. Pursuant to the Merger, all

of shares of the outstanding capital stock of the Company and shares subject to
outstanding options and warrants as is indicated on the signature page of this
Agreement; and

     C. In consideration of the execution of the Reorganization Agreement by
Parent, Stockholder agrees to vote the Shares (as defined below) and other such
shares of capital stock of the Company over which Stockholder has voting power
so as to facilitate consummation of the Merger.

     NOW, THEREFORE, intending to be legally bound, the parties hereto agree as

(a "Third Party"), acquires more than 20% of the outstanding shares of the
Company common stock pursuant to a tender offer or exchange offer or otherwise,
(ii) a merger or other business combination involving the Company pursuant to
which any Third Party acquires more than 20% of the outstanding shares of
Company common stock or of the entity surviving such merger or business
combination, (iii) any other transaction pursuant to which any Third Party

securities of Subsidiaries of the Company, and the entity surviving any merger
or business combination including any of them) of the Company having a fair
market value equal to more than 20% of the fair market value of all the assets
of the Company immediately prior to such transaction, or (iv) any public
announcement by a Third Party of a proposal, plan or intention to do any of the
foregoing or any agreement to engage in any of the foregoing.

     (a) "Expiration Date" shall mean the earlier to occur of (i) such date and

grants an option with respect to, transfers or disposes of such security or any
interest in such security; or (ii) enters into an agreement or commitment
providing for the sale of, pledge of, encumbrance of, grant of an option with

Shares) subject to all of the terms and provisions of this Agreement.

     (b) Transfer of Voting Rights. Stockholder agrees that, during the period
from the date of this Agreement through the Expiration Date, Stockholder shall
not deposit (or permit the deposit of) any Shares in a voting trust or grant any

the Shares.

     3. Agreement to Vote Shares. At every meeting of the stockholders of the
Company called, and at every adjournment thereof, and on every action or
approval by written consent of the stockholders of the Company, Stockholder
shall cause the Shares to be voted (a) in favor of approval of the
Reorganization Agreement, as modified or amended from time to time in accordance
with its terms and with the approval of the Board of Directors of the Company,
and the Merger and (b) against any other Alternative Transaction.

     4. Irrevocable Proxy. Concurrently with the execution of this Agreement,

stockholder, to execute and delivery any additional documents necessary or
desirable, in the reasonable opinion of Parent, to carry out the intent of this
Agreement.

     7. Consent and Waiver. Stockholder (not in any other capacity) hereby gives
any consents or waivers that are reasonably required for the consummation of the
Merger under the terms of any agreements to which Stockholder is a party or

                           NON-COMPETITION AGREEMENT

     THIS NON-COMPETITION AGREEMENT (the "AGREEMENT") is made as of the
Effective Date (as defined below) by and among OnDisplay, Inc., a Delaware
corporation ("ONDISPLAY"), Oberon Software Incorporated, a Massachusetts
corporation, including any and all of its subsidiaries (collectively, "OSI") and
the undersigned employee ("EMPLOYEE"). Capitalized terms used but not otherwise
defined herein shall have the meanings ascribed to them in the Reorganization
Agreement (as defined below).

                                   BACKGROUND

     A. OnDisplay, ObiOne Acquisition Corporation, a Delaware corporation and
wholly-owned subsidiary of OnDisplay ("SUB"), and OSI have entered into an
Agreement and Plan of Reorganization dated as of January   , 2000 (the
"REORGANIZATION AGREEMENT"), which provides for the merger (the "MERGER") of Sub
with and into OSI. The effective date of the consummation of the Merger shall be
the "EFFECTIVE DATE" of this Agreement.

     B. Employee is receiving significant consideration pursuant to the terms of
the Reorganization Agreement.

     C. As a condition to the Merger, to preserve the value of the business
being acquired by OnDisplay, the Reorganization Agreement contemplates, among
other things, that Employee enter into this Agreement and that this Agreement
become effective upon the closing of the Merger.

     D. OSI is currently engaged or planning to engage in its business in each
of the fifty (50) states of the United States and worldwide. OnDisplay,
following the Merger, will continue conducting such business in all parts of the
United States and worldwide.

     NOW THEREFORE, in consideration of the mutual promises made herein,
OnDisplay and Employee (collectively referred to as the "PARTIES") hereby agree
as follows:

     1. Covenant Not to Compete or Solicit.

          (a) For the later of twenty-four (24) months after the Effective Date
     (the "NON-COMPETE PERIOD") or twelve (12) months after the date Employee
     ceases to be employed by OnDisplay, or OSI, Employee shall not directly or
     indirectly, without the prior written consent of OnDisplay, (i) as an
     individual proprietor, partner, stockholder, officer, employee, director,
     consultant, joint venturer, investor, lender or in any other capacity
     whatsoever (other than as the holder of not more than one percent (1%) of
     the total outstanding stock of a publicly held company), engage in any
     business which develops, produces, markets or offers any products or
     services which are competitive with any products being developed, produced
     or marketed, or with any services being offered or being proposed to be
     offered, by OSI or OnDisplay at any time during the term of my employment
     with OSI or OnDisplay; or (ii) approach, contact, solicit or interfere with
     the business of OnDisplay's or OSI's customers which are presently existing
     or which are existing on the date of Employee's termination from OnDisplay
     or OSI to the extent relating to a competing business purpose.

          (b) During the Non-Compete Period, Employee shall not, directly or
     indirectly, without the prior written consent of OnDisplay, (i) solicit,
     encourage, hire or take any other action which is intended to induce any
     employee of OnDisplay or OSI to terminate his or her employment with
     OnDisplay or OSI or (ii) interfere in any manner with the contractual or
     employment relationship between either OnDisplay or OSI and any employee of
     OnDisplay or OSI, respectively.

          (c) The covenants contained in the preceding paragraphs shall be
     construed as a series of separate covenants, one for each county, city and
     state of any geographic area where any business is presently carried on by
     OSI or OnDisplay. Except for geographic coverage, each such separate

                                      A-53
<PAGE>   210

     covenant shall be identical in terms to the covenant contained in the
     preceding paragraphs. If, in any judicial proceeding, a court refuses to
     enforce any of such separate covenants (or any part thereof), then such
     unenforceable covenant (or such part) shall be eliminated from this
     Agreement to the extent necessary to permit the remaining separate
     covenants (or portions thereof) to be enforced. In the event that the
     provisions of this Section 1 are deemed to exceed the time, geographic or
     scope limitations permitted by applicable law, then such provisions shall
     be reformed to the maximum time, geographic or scope limitations, as the
     case may be, permitted by applicable laws.

          (d) Employee acknowledges that breach of this Section 1 would cause
     irreparable injury to OnDisplay and OSI and agrees that in the event of
     such breach, OnDisplay or OSI shall be entitled to seek injunctive relief
     without the necessity of proving actual damages.

     2. Miscellaneous.

     (a) Severability. If any portion of this Agreement is held by a court of
competent jurisdiction to conflict with any federal, state or local laws, such
portion of this Agreement shall be of no force or effect and this Agreement
shall otherwise remain in full force and effect and be construed as if such
portion had not been included in this Agreement.

     (b) No Assignment. Employee shall not assign this Agreement or any rights
or obligations under this Agreement without the prior written consent of
OnDisplay and OSI.

     (c) Notice. All notices and other communications hereunder shall be in
writing and shall be deemed given if delivered personally or by commercial
delivery service, or mailed by registered or certified mail (return receipt
requested) or sent via facsimile (with acknowledgement of complete transmission)

                                   BACKGROUND

     A. OnDisplay, ObiOne Acquisition Corporation, a Delaware corporation and
wholly-owned subsidiary of OnDisplay ("SUB"), and OSI have entered into an
Agreement and Plan of Reorganization dated as of January   , 2000 (the
"REORGANIZATION AGREEMENT"), which provides for the merger (the "MERGER") of Sub
with and into OSI. The effective date of the consummation of the Merger shall be
the "EFFECTIVE DATE" of this Agreement.

     B. Employee is receiving significant consideration pursuant to the terms of
the Reorganization Agreement.

     C. As a condition to the Merger, to preserve the value of the business
being acquired by OnDisplay, the Reorganization Agreement contemplates, among
other things, that Employee enter into this Agreement and that this Agreement
become effective upon the closing of the Merger.

     D. OSI is currently engaged or planning to engage in its business in each
of the fifty (50) states of the United States and worldwide. OnDisplay,
following the Merger, will continue conducting such business in all parts of the
United States and worldwide.

     NOW THEREFORE, in consideration of the mutual promises made herein,
OnDisplay and Employee (collectively referred to as the "PARTIES") hereby agree
as follows:

     1. Covenant Not to Compete or Solicit.

     (a) For the later of eighteen (18) months after the Effective Date (the

employed by OnDisplay, or OSI, Employee shall not directly or indirectly,
without the prior written consent of OnDisplay, (i) as an individual proprietor,
partner, stockholder, officer, employee, director, consultant, joint venturer,
investor, lender or in any other capacity whatsoever (other than (i) as the
holder of not more than one percent (1%) of the total outstanding stock of a
publicly held company or as a "passive" investment in a limited partnership or
similar entity in which Employee owns not more than 2.5% of the equity interest,
(ii) investments in mutual funds which hold solely publicly traded securities,
or (iii) investments in a blind trust in which Employee has no input or control
over the investment selection), engage in any business which develops, produces,
markets or offers any products or services which are competitive with any
products being developed, produced or marketed, or with any services being
offered or being proposed to be offered, by OSI or OnDisplay at any time during
the term of my employment with OSI or OnDisplay; or (ii) approach, contact,
solicit or interfere with the business of OnDisplay's or OSI's customers which
are presently existing or which are existing on the date of Employee's
termination from OnDisplay or OSI to the extent relating to a competing business
purpose.

     (b) During the Non-Compete Period, Employee shall not, directly or
indirectly, without the prior written consent of OnDisplay, (i) solicit,
encourage, hire or take any other action which is intended to induce any
employee of OnDisplay or OSI to terminate his or her employment with OnDisplay
or OSI or (ii) interfere in any manner with the contractual or employment
relationship between either OnDisplay or OSI and any employee of OnDisplay or
OSI, respectively.

     (c) The covenants contained in the preceding paragraphs shall be construed
as a series of separate covenants, one for each county, city and state of any
geographic area where any business is presently carried on by OSI or OnDisplay.
Except for geographic coverage, each such separate covenant shall be identical
in terms to the covenant contained in the preceding paragraphs. If, in any
judicial proceeding, a court refuses to enforce any of such separate covenants
(or any part thereof), then such unenforceable covenant (or such part) shall be
eliminated from this Agreement to the extent necessary to permit the remaining
separate covenants (or portions thereof) to be enforced. In the event that the
provisions of this Section 1 are deemed to exceed the time, geographic or scope
limitations permitted by applicable law, then such provisions shall be reformed
to the maximum time, geographic or scope limitations, as the case may be,
permitted by applicable laws.

     (d) Employee acknowledges that breach of this Section 1 would cause
irreparable injury to OnDisplay and OSI and agrees that in the event of such
breach, OnDisplay or OSI shall be entitled to seek injunctive relief without the
necessity of proving actual damages.

and Exchange Commission (the "SEC") and of Opinion 16 of the Accounting
Principles Board and applicable SEC rules and regulations.

     C. The execution and delivery of this Agreement by Affiliate is a material
inducement to Parent to enter into the Reorganization Agreement.

     NOW, THEREFORE, intending to be legally bound, the parties hereto agree as
follows:

     1. Acknowledgments by Affiliate. Affiliate acknowledges and understands
that the representations, warranties and covenants by Affiliate set forth herein
shall be relied upon by Parent, the Company and their respective affiliates,
counsel and accounting firms, and that substantial losses and damages may be
incurred by these persons if Affiliate's representations, warranties or
covenants are breached. Affiliate has carefully read this Agreement and the
Reorganization Agreement and has discussed the requirements of this Agreement
with Affiliate's professional advisors, who are qualified to advise Affiliate
with regard to such matters.

     2. Beneficial Ownership of Company capital stock. The Affiliate is the sole
record and beneficial owner of the number of shares of Company capital stock set
forth next to its name on the signature page hereto (the "Shares"). The Shares
are not subject to any claim, lien, pledge, charge, security interest or other
encumbrance or to any rights of first refusal of any kind. There are no options,
warrants, calls, rights, commitments or agreements of any character, written or
oral, to which the Affiliate is party or by which it is bound obligating the
Affiliate to issue, deliver, sell, repurchase or redeem, or cause to be issued,
delivered, sold, repurchased or redeemed, any Shares or obligating the Affiliate
to grant or enter into any such option, warrant, call, right, commitment or
agreement. The Affiliate has the sole right to transfer such Shares. The Shares
constitute all shares of Company capital stock owned, beneficially or of record,
by the Affiliate. The Shares are not subject to preemptive rights created by any
agreement to which the Affiliate is party. The Affiliate has not engaged in any
sale or other transfer of the Shares in contemplation of the Merger. All shares
of Company capital stock and common stock of Parent ("Parent common stock")
acquired by Affiliate subsequent to the date hereof (including shares of Parent
common stock acquired in the Merger) shall be subject to the provisions of this
Agreement as if held by Affiliate as of the date hereof.

     3. Compliance with Rule 145 and the Securities Act.

          (a) Affiliate has been advised that (i) the issuance of shares of
     Parent common stock in connection with the Merger is expected to be
     effected pursuant to a registration statement on Form S-4 promulgated under
     the Securities Act of 1933, as amended (the "Securities Act"), and the
                                      A-95
<PAGE>   252

     resale of such shares shall be subject to restrictions set forth in Rule
     145 under the Securities Act, and (ii) Affiliate may be deemed to be an
     affiliate of the Company. Affiliate accordingly agrees not to sell,
     transfer or otherwise dispose of any Parent common stock issued to
     Affiliate in the Merger unless (i) such sale, transfer or other disposition
     is made in conformity with the requirements of Rule 145(d) promulgated
     under the Securities Act, or (ii) such sale, transfer or other disposition
     is made pursuant to an effective registration statement under the
     Securities Act or an appropriate exemption from registration, or (iii)
     Affiliate delivers to Parent a written opinion of counsel, reasonably
     acceptable to Parent in form and substance, that such sale, transfer or
     other disposition is otherwise exempt from registration under the
     Securities Act.

          (b) Parent shall give stop transfer instructions to its transfer agent
     with respect to any Parent common stock received by Affiliate pursuant to
     the Merger and there shall be placed on the certificates representing such
     common stock, or any substitutions therefor, a legend stating in substance:

        "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION
        TO WHICH RULE 145 APPLIES AND MAY ONLY BE TRANSFERRED IN CONFORMITY WITH
        RULE 145(d) OR PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED, OR IN ACCORDANCE WITH A WRITTEN
        OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO THE ISSUER IN FORM AND
        SUBSTANCE, THAT SUCH TRANSFER IS EXEMPT FROM REGISTRATION UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED."

     The legend set forth above shall be removed (by delivery of a substitute
certificate without such legend) and Parent shall so instruct its transfer
agent, if Affiliate delivers to Parent (i) satisfactory written evidence that
the shares have been sold in compliance with Rule 145 (in which case, the
substitute certificate shall be issued in the name of the transferee), or (ii)
an opinion of counsel, in form and substance reasonably satisfactory to Parent,
to the effect that public sale of the shares by the holder thereof is no longer
subject to Rule 145.

     4. Termination. This Agreement shall be terminated and shall be of no
further force and effect in the event of the termination of the Reorganization
Agreement pursuant to Article VIII of the Reorganization Agreement.

     5. Miscellaneous.

          (a) Waiver; Severability. No waiver by any party hereto of any
     condition or of any breach of any provision of this Agreement shall be
     effective unless in writing and signed by each party hereto. In the event
     that any provision of this Agreement, or the application of any such
     provision to any person, entity or set of circumstances, shall be
     determined to be invalid, unlawful, void or unenforceable to any extent,
     the remainder of this Agreement, and the application of such provision to
     persons, entities or circumstances other than those as to which it is
     determined to be invalid, unlawful, void or unenforceable, shall not be
     impaired or otherwise affected and shall continue to be valid and
     enforceable to the fullest extent permitted by law.

          (b) Binding Effect and Assignment. This Agreement and all of the
     provisions hereof shall be binding upon and inure to the benefit of the
     parties hereto and their respective successors and permitted assigns, but,
     except as otherwise specifically provided herein, neither this Agreement
     nor any of the rights, interests or obligations of the parties hereto may
     be assigned by either of the parties without prior written consent of the
     other party hereto.

          (c) Amendments and Modification. This Agreement may not be modified,
     amended, altered or supplemented except upon the execution and delivery of
     a written agreement executed by the parties hereto.

          (d) Injunctive Relief. Each of the parties acknowledge that (i) the
     covenants and the restrictions contained in this Agreement are necessary,
     fundamental, and required for the protection of Parent and the Company and
     to preserve for Parent the benefits of the Merger; (ii) such covenants

                                      A-96
<PAGE>   253

     relate to matters which are of a special, unique, and extraordinary
     character that gives each of such covenants a special, unique, and
     extraordinary value; and (iii) a breach of any such covenants or any other
     provision of this Agreement shall result in irreparable harm and damages to
     Parent and the Company which cannot be adequately compensated by a monetary
     award. Accordingly, it is expressly agreed that in addition to all other
     remedies available at law or in equity, Parent and the Company shall be
     entitled to the immediate remedy of a temporary restraining order,
     preliminary injunction, or such other form of injunctive or equitable
     relief as may be used by any court of competent jurisdiction to restrain or
     enjoin any of the parties hereto from breaching any such covenant or
     provision or to specifically enforce the provisions hereof.

          (e) Governing Law. This Agreement shall be governed by and construed,
     interpreted and enforced in accordance with the internal laws of the State
     of Delaware without giving effect to any choice or conflict of law
     provision or rule (whether of the State of Delaware or any other
     jurisdiction) that would cause the application of the laws of any
     jurisdiction other than the State of Delaware.

          (f) Entire Agreement. This Agreement, the Reorganization Agreement and
     any other agreements referred to in the Reorganization Agreement set forth
     the entire understanding of Affiliate and Parent relating to the subject
     matter hereof and thereof and supersede all prior agreements and
     understandings between Affiliate and Parent relating to the subject matter
     hereof and thereof.

          (g) Attorneys' Fees. In the event of any legal actions or proceeding
     to enforce or interpret the provisions hereof, the prevailing party shall
     be entitled to reasonable attorneys' fees, whether or not the proceeding
     results in a final judgment.

          (h) Further Assurances. Affiliate shall execute and/or cause to be
     delivered to Parent such instruments and other documents and shall take
     such other actions as Parent may reasonably request to effectuate the
     intent and purposes of this Agreement.

          (i) Third Party Reliance. Counsel to and independent auditors for
     Parent and the Company shall be entitled to rely upon this Affiliate
     Agreement.

          (j) Survival. The representations, warranties, covenants and other
     provisions contained in this Agreement shall survive the Merger.

          (k) Notices. All notices and other communications pursuant to this
     Agreement shall be in writing and deemed to be sufficient if contained in a
     written instrument and shall be deemed given if delivered personally,
     telecopied, sent by nationally-recognized overnight courier or mailed by
     registered or certified mail (return receipt requested), postage prepaid,

                                January 17, 2000

Board of Directors
OnDisplay, Inc.
12667 Alcosta Blvd.,
Suite 300
San Ramon, CA 94583

Members of the Board:

     We understand that Oberon Software Incorporated (the "Company"), OnDisplay,
Inc. ("Acquiror") and ObiOne Acquisition Corporation (a wholly owned subsidiary
of Acquiror, "Merger Sub") are proposing to enter into an Agreement and Plan of
Reorganization (the "Agreement") which will provide, among other things, for the
merger (the "Merger") of Merger Sub with and into the Company. Upon consummation
of the Merger, the Company will become a wholly owned subsidiary of Acquiror.
Under the terms set forth in a draft of the Agreement dated January 17, 2000
(the "Draft Agreement"), at the effective time of the Merger, each of the
outstanding shares of common stock of the Company, par value $.01 per share,
Series 1 Participating Convertible Preferred Stock, par value $.01 per share and
Series 2, Non-Participating Convertible Preferred Stock, par value $.01 per
share (collectively, "Company Capital Stock") other than certain shares to be
canceled pursuant to the Agreement and shares held by stockholders who properly
exercise dissenters' rights ("Dissenting Shares"), will be converted into the
right to receive .0912 shares (the "Exchange Ratio") of the common stock of
Acquiror, par value $0.001 per share ("Acquiror Common Stock"). Outstanding
options to acquire Company Capital Stock will be assumed and converted into
options to acquire Acquiror Common Stock pursuant to the terms of the Agreement.
The terms and conditions of the Merger are set out more fully in the Agreement.

     You have asked us whether, in our opinion, the Exchange Ratio is fair from
a financial point of view and as of the date hereof to Acquiror.

     For purposes of this opinion we have, among other things:

     (i)    reviewed certain internal financial statements and other financial
            and operating data, including certain financial forecasts and other
            forward looking information, concerning (a) the Company prepared by
            the managements of the Company and Acquiror, respectively, and (b)
            Acquiror prepared by the management of Acquiror;

     (ii)   reviewed with Acquiror certain publicly available research estimates
            of research analysts regarding Acquiror;

     (iii)  held discussions with the respective managements of the Company and
            Acquiror concerning the businesses, past and current operations,
            financial condition and future prospects of both the Company and
            Acquiror, independently and combined, including discussions with the
            managements of the Company and Acquiror concerning their views
            regarding the strategic rationale for the Merger;

     (iv)  reviewed the financial terms and conditions set forth in the Draft
           Agreement, dated January 17, 2000;

     (v)   reviewed the stock price and trading history of Acquiror Common
           Stock;

     (vi)  compared the financial performance of the Company with that of
           certain publicly traded companies that we deemed comparable with the
           Company;

     (vii)  compared the financial terms of the Merger with the financial terms,
            to the extent publicly available, of other transactions that we
            deemed relevant;

     (viii)  reviewed the pro forma impact of the Merger on Acquiror's revenue
             per share and earnings per share;

                                       B-1

     (ix)  prepared an analysis of the relative contributions of the Company and
           Acquiror to the combined company;

     (x)   participated in discussions and negotiations among representatives of
           the Company and Acquiror and their financial and legal advisors; and

     (xi)  made such other studies and inquiries, and reviewed such other data,
           as we deemed relevant.

     In our review and analysis, and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information provided to us (including information furnished to us orally or
otherwise discussed with us by the managements of the Company and Acquiror) or
publicly available and have neither attempted to verify, nor assumed
responsibility for verifying, any of such information. We have relied upon the
assurances of the managements of the Company and Acquiror that they are not
aware of any facts that would make such information inaccurate or misleading.
Furthermore, we did not obtain or make, or assume any responsibility for
obtaining or making, any independent evaluation or appraisal of the properties,
assets or liabilities (contingent or otherwise) of the Company or Acquiror, nor
were we furnished with any such evaluation or appraisal. With respect to the
financial forecasts and projections (and the assumptions and bases therefor) for
each of the Company and Acquiror that we have reviewed, upon the advice of the
managements of the Company and Acquiror, we have assumed that such forecasts and
projections have been reasonably prepared in good faith on the basis of
reasonable assumptions and reflect the best currently available estimates and
judgments as to the future financial condition and performance of the Company
and Acquiror, respectively, and we have further assumed that such projections
and forecasts will be realized in the amounts and in the time periods currently
estimated. In this regard, we note that each of the Company and the Acquiror
face exposure to the Year 2000 problem. We have not undertaken any independent
analysis to evaluate the reliability or accuracy of the assumptions made with
respect to the potential effect that the Year 2000 problem might have on the
Company's and the Acquiror's respective forecasts. We have assumed that the
Merger will be consummated upon the terms set forth in the Draft Agreement
without material alteration thereof, including, among other things, that the
Merger will be accounted for as a "purchase method" business combination in
accordance with U.S. generally accepted accounting principles ("GAAP") and that
the Merger will be treated as a tax-free reorganization pursuant to the Internal
Revenue Code of 1986, as amended. In addition, we have assumed that the
historical financial statements of each of the Company and Acquiror reviewed by
us have been prepared and fairly presented in accordance with U.S. GAAP
consistently applied. We have also assumed that the Exchange Ratio will not be
increased as a result of provisions of the Draft Agreement. We have relied as to
all legal matters relevant to rendering our opinion on the advice of counsel.

     This opinion is necessarily based upon market, economic and other
conditions as in effect on, and information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect the
conclusion expressed in this opinion and that we disclaim any undertaking or
obligation to advise any person of any change in any matter affecting this
opinion which may come or be brought to our attention after the date of this
opinion. Our opinion is limited to the fairness, from a financial point of view
and as of the date hereof, to Acquiror of the Exchange Ratio. We do not express
any opinion as to (i) the value of any employee agreement or other arrangement
entered into in connection with the Merger, (ii) any tax or other consequences
that might result from the Merger or (iii) what the value of Acquiror Common
Stock will be when issued to the Company's stockholders pursuant to the Merger
or the price at which shares of Acquiror Common Stock may be traded in the
future. Our opinion does not address the relative merits of the Merger and the
other business strategies that Acquiror's Board of Directors has considered or
may be considering, nor does it address the decision of Acquiror's Board of
Directors to proceed with the Merger.

     We will receive a fee contingent upon the delivery of this opinion, and
Acquiror has agreed to indemnify us for certain liabilities that may arise out
of our engagement. In the past, we have provided certain investment banking
services to the Acquiror for which we have been paid fees, including acting as
lead manager for the initial public offering of Acquiror Common Stock. We
maintain a market in the shares of Acquiror Common Stock. In the ordinary course
of business, we may trade in Acquiror's securities for our own account and the
account of our customers and, accordingly, may at any time hold a long or short
position in Acquiror's securities.

     Our opinion expressed herein is provided for the information of the Board
of Directors of Acquiror in connection with its evaluation of the Merger. Our
opinion is not intended to be and does not constitute a recommendation to any
stockholder of Acquiror or the Company as to how such stockholder should vote,
or take any other action, with respect to the Merger. This opinion may not be
summarized, described or referred to or furnished to any party except with our
express prior written consent.

     Based upon and subject to the foregoing considerations, it is our opinion
that, as of the date hereof, the Exchange Ratio is fair to Acquiror from a
financial point of view.

                                       Very truly yours,

January 16, 2000

Special Committee of the Board of Directors
Oberon Software Incorporated
215 First Street
Cambridge, MA 02142

Gentlemen:

     We understand that OnDisplay, Inc. ("OnDisplay"), ObiOne Acquisition Corp.
("Merger Sub"), a wholly owned subsidiary of OnDisplay, and Oberon Software
Incorporated ("Oberon" or the "Company") are considering entering into an
agreement and plan of reorganization substantially in the form of the draft
dated January 13, 2000 (the "Draft Merger Agreement") pursuant to which, among
other things, Merger Sub shall be merged with and into the Company in a
transaction (the "Merger") in which each share of Common Stock and Preferred
Stock of the Company, subject to the conditions and limitations set forth in the
Draft Merger Agreement, shall be converted into the right to receive, without
interest, 0.0911596 shares (the "Exchange Ratio") of the Common Stock of
OnDisplay. The terms and conditions of the Merger are set forth in more detail
in the Draft Merger Agreement, a copy of which has been furnished to us.

     You have requested the opinion of SoundView Technology Group, Inc.
("SoundView"), as of this date, as to the fairness, from a financial point of
view, to the stockholders of the Company, of the Exchange Ratio.

     In conducting our analysis and arriving at our opinion as expressed herein,
we have, among other things:

          (i) reviewed the Draft Merger Agreement and the specific terms of the
     Merger set forth therein, and have assumed that the final form of the Draft
     Merger Agreement will not vary in any regard that is material to our
     analysis;

          (ii) reviewed Oberon's financial and operating information for the
     two-year period ended September 30, 1999 and the three-month period ended
     December 31, 1999;

          (iii) reviewed OnDisplay's financial and operating information for the
     two year period ended December 31, 1999;

          (iv) reviewed certain financial and operating information regarding
     the businesses, operations and prospects of Oberon and OnDisplay, including
     forecasts and projections, provided to us by the managements of the Company
     and OnDisplay, respectively;

          (v) reviewed certain publicly available financial information
     concerning certain other companies we deemed to be reasonably similar to
     the Company and OnDisplay and the trading markets for certain of such
     companies' securities;

          (vi) reviewed the financial terms of the Merger and compared them with
     the financial terms, to the extent publicly available, of certain recent
     mergers and acquisitions that we deemed relevant;

          (vii) conducted discussions with certain members of senior management
     of the Company and OnDisplay concerning their respective business and
     operations, assets, present condition and future prospects; and

          (viii) performed such other analyses, examinations and procedures,
     reviewed such other agreements and documents, and considered such other
     factors as we have deemed, in our sole judgment, to be necessary,
     appropriate or relevant to render the opinion set forth herein.

     We have also taken into account our assessment of general economic, market
and financial conditions and our experience in similar transactions, as well as
our experience in securities valuation in general. Our opinion is necessarily
based upon conditions as they exist and can be evaluated on the date hereof.

     In arriving at our opinion, we have not made, obtained or assumed any
responsibility for any independent evaluation or appraisal of the properties and
facilities or of the assets and liabilities (contingent or otherwise) of either
the Company or OnDisplay. We have assumed and relied upon the accuracy and
completeness of the financial and other information supplied to or otherwise
used by us in arriving at our opinion and have not attempted independently to
verify, or undertaken any obligation to verify, such information. We have
further relied upon the assurances of the managements of Oberon and OnDisplay
that they were not aware of any facts that would make such information
inaccurate or misleading. In addition, we have assumed that the forecasts and
projections provided to SoundView by OnDiplay and the Company represent the best
currently available estimates and judgments of OnDisplay's and the Company's
managements as to the future financial condition and results of operations of
OnDisplay and the Company, respectively, and have assumed that such forecasts
and projects have been reasonably prepared based on such currently available
estimates and judgments. We assume no responsibility for and express no view as
to such forecasts and projections or the assumptions on which they are based.

     We do not express any opinion as to the price at which OnDisplay's stock
will trade prior to or subsequent to the closing of the Merger. This letter does
not constitute a recommendation of the Merger over any other alternative
transactions which may be available to the Company and does not address the
underlying business decision of the Special Committee of the Board of Directors
of the Company to proceed with or effect the Merger.

     SoundView, as part of its investment banking services, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, divestitures, restructurings, recapitalizations, underwritings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. We have been engaged to render
the financial opinion as expressed herein and we will receive a fee upon
delivery of this opinion. We also, from time to time, may in the future perform
certain financial advisory services for the Company for which we may receive a
fee. In the ordinary course of business, we may actively trade the securities of
OnDisplay for our own account and for the accounts of our customers and,
accordingly, may at any time hold a short or long position in such securities.
The Company has agreed to indemnify us for certain liabilities that may arise
out of the rendering of this opinion.

     This opinion has been prepared for the confidential use and benefit of the
Special Committee of the Board of Directors of the Company in its consideration
of the Merger, supersedes any previously rendered opinion and may not be
reproduced, summarized, described or referred to or given to any other person or
otherwise made public without our prior written consent.

     Based upon and subject to the foregoing, it is our opinion as investment
bankers that, as of the date hereof, the Exchange Ratio pursuant to the Draft
Merger Agreement is fair, from a financial point of view, to the Company's
stockholders.

                                          Very truly yours,

                                          /s/  SoundView Technology Group, Inc.

sections eighty-seven to ninety-eight, inclusive, shall apply except as
otherwise specifically provided in any section of this chapter. Except as
provided in sections eighty-two and eighty-three, no stockholder shall have such
right unless (1) he files with the corporation before the taking of the vote of
the shareholders on such corporate action, written objection to the proposed
action stating that he intends to demand payment for his shares if the action is
taken and (2) his shares are not voted in favor of the proposed action.

MEETING; FORM

     The notice of the meeting of stockholders at which the approval of such
proposed action is to be considered shall contain a statement of the rights of
objecting stockholders. The giving of such notice shall not be deemed to create
any rights in any stockholder receiving the same to demand payment for his
stock, and the directors may authorize the inclusion in any such notice of a
statement of opinion by the management as to the existence or non-existence of
the right of the stockholders to demand payment for their stock on account of
the proposed corporate action.

     St.1973, c. 749, sec. 749, approved Sept. 7, 1973, in the first sentence,

behalf of all other stockholders who have demanded payment for their shares and
with whom the corporation has not reached agreement as to the value thereof, and
service of the bill shall be made upon the corporation by subpoena with a copy
of the bill annexed. The corporation shall file with its answer a duly verified
list of all such other stockholders, and such stockholders shall thereupon be
deemed to have been added as parties to the bill. The corporation shall give
notice in such form and returnable on such date as the court shall order to each
stockholder party to the bill by registered or certified mail, addressed to the
last known address of such stockholder as shown in the records of the
corporation, and the court may order such additional notice by publication or
otherwise as it deems advisable. Each stockholder who makes demand as provided
in section eighty-nine shall be deemed to have consented to the provisions of
this section relating to notice, and the giving of notice by the corporation to
any such stockholder in compliance with the order of the court shall be a
sufficient service of process on him. Failure to give notice to any stockholder
making demand shall not invalidate the proceedings as to other stockholders to
whom notice was properly given, and the court may at any time before the entry
of a final decree make supplementary orders of notice.

Added by St.1964, c. 723, sec. 1.

156B SEC. 92. DECREE DETERMINING VALUE AND ORDERING PAYMENT; VALUATION DATE

the stock of those stockholders who have become entitled to the valuation of any
payment for their shares, and shall order the corporation to make payment of
such value, together with interest, if any, as hereinafter provided, to the
stockholders entitled thereto upon the transfer by them to the corporation of
the certificates

corporate action.

thereunder to a special master to hear the parties, make findings and report the
same to the court, all in accordance with the usual practice in suits in equity
in the superior court.

of any master appointed by the court, but exclusive of fees of counsel or of
experts retained by any party, shall be determined by the court and taxed upon

award from the date of the vote approving the proposed corporate action, and the

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act. The
Registrant's Bylaws provide for the mandatory indemnification of its directors,
officers, employees and other agents to the maximum extent permitted by Delaware
General Corporation Law, and the Company has entered into agreements with its
officers, directors and certain key employees implementing such indemnification.

ITEM 22. UNDERTAKINGS

     (1) The undersigned Registrant hereby undertakes as follows: that prior to
any public offering 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

                                      II-1
<PAGE>   267

undersigned Registrant undertakes that such offering 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.

     (2) The Registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the 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 of 1933, 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) Insofar as the indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to Directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     (4) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus 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.

     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.

     RE: REGISTRATION STATEMENT ON FORM S-4

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-4 to be filed by you
with the Securities and Exchange Commission on or about March 3, 2000 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of shares of your Common Stock (the
"Shares"). As your counsel in connection with this transaction, we have
examined the proceedings taken and are familiar with the proceedings proposed
to be taken by you in connection with the issuance of the Shares pursuant to
the acquisition transaction set forth and described in the Registration
Statement.

     It is our opinion that, when issued in the manner described in the
Registration Statement, the Shares will be legally and validly issued,
fully-paid and non-assessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name whenever appearing in the
Registration Statement and any amendments thereto.

                                        Very truly yours,

                                        /s/ Wilson Sonsini Goodrich & Rosati

                                 March 3, 2000



OnDisplay, Inc.
12667 Alcosta Boulevard, Suite 300
San Ramon, CA 94583

Ladies and Gentlemen:

        We have acted as counsel to OnDisplay, Inc., a Delaware corporation
("OnDisplay") in connection with the proposed merger (the "Merger") among
OnDisplay, ObiOne Acquisition Corporation, a Delaware corporation (?Merger Sub?)
and wholly-owned transitory merger subsidiary of OnDisplay, and Oberon Software
Incorporated, a Massachusetts corporation ("Oberon") pursuant to an Agreement
and Plan of Reorganization dated as of January 17, 2000, (the "Merger
Agreement"). The Merger and certain proposed transactions incident thereto are
described in the Registration Statement on Form S-4 (the "Registration
Statement") of OnDisplay which includes the Proxy Statement/Prospectus of Oberon
and OnDisplay (the "Proxy Statement/Prospectus"). This opinion is being rendered
pursuant to the requirements of Item 21(a) of Form S-4 under the Securities Act
of 1933, as amended. Unless otherwise indicated, any capitalized terms used
herein and not otherwise defined have the meaning ascribed to them in the Proxy
Statement/Prospectus.

        In connection with this opinion, we have examined and are familiar with
the Merger Agreement, the Registration Statement, and such other presently
existing documents, records and matters of law as we have deemed necessary or
appropriate for purposes of our opinion. In addition, we have assumed (i) that
the Merger will be consummated in the manner contemplated by the Proxy
Statement/Prospectus and in accordance with the provisions of the Merger
Agreement, (ii) the truth and accuracy of the representations and warranties
made by OnDisplay and Oberon in the Merger Agreement, and (iii) the truth and
accuracy of the certificates of representations to be provided to us by
OnDisplay, Oberon and Merger Sub.

        Based upon and subject to the foregoing, in our opinion, the discussion
contained in the Registration Statement under the caption "Material United
States federal income tax considerations of the Oberon merger," subject to the
limitations and qualifications described therein, sets forth the material United
States Federal income tax considerations generally applicable to the Merger.
Because this opinion is being delivered prior to the Effective Time of the
Merger, it must be considered prospective and dependent on future events. There
can be no assurance that changes in the law will not take place which could
affect

the United States Federal income tax consequences of the Merger or that contrary
positions may not be taken by the Internal Revenue Service.

        This opinion is furnished to you solely for use in connection with the
Registration Statement. We hereby consent to the filing of this opinion as
Exhibit 8.1 to the Registration Statement. We also consent to the reference to
our firm name wherever appearing in the Registration Statement with respect to
the discussion of the material federal income tax consequences of the Merger,
including the Proxy Statement/Prospectus constituting a part thereof, and any
amendment thereto. In giving this consent, we do not thereby admit that we are
in the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder, nor do we thereby admit that we
are experts with respect to any part of such Registration Statement within the
meaning of the term "experts" as used in the Securities Act of 1933, as amended,
or the rules and regulations of the Securities and Exchange Commission
thereunder.

                                Very truly yours,

        Re:    Merger pursuant to Agreement and Plan of Reorganization
               among OnDisplay, Inc., ObiOne Acquisition Corporation,
               and Oberon Software Incorporated

Ladies and Gentlemen:

        This opinion is being delivered to you in connection with the filing of
a registration statement (the "Registration Statement") on Form S-4, which
includes the Proxy Statement and Prospectus relating to the Agreement and Plan
of Reorganization dated as of January 17, 2000 (the "Merger Agreement"), by and
among OnDisplay, Inc., a Delaware corporation ("Parent"), ObiOne Acquisition
Corporation, a Delaware corporation and wholly owned subsidiary of Parent
("Sub"), and Oberon Software Incorporated, a Massachusetts corporation
("Target"). Pursuant to the Merger Agreement, Sub will merge with and into
Target (the "Merger"). Except as otherwise provided, capitalized terms not
defined herein have the meanings set forth in the Merger Agreement and the
exhibits thereto or in the letters delivered to Hale and Dorr LLP by Parent and
Target containing certain representations of Parent and Target relevant to this
opinion (the "Representation Letters"). All section references, unless otherwise
indicated, are to the United States Internal Revenue Code of 1986, as amended
(the "Code").

        In our capacity as counsel to Target in the Merger, and for purposes of
rendering this opinion, we have examined and relied upon the Registration
Statement, the Merger Agreement and the exhibits thereto, including the Escrow
Agreement, the Representation Letters, and such other documents as we considered
relevant to our analysis. In our examination of documents, we have assumed the
authenticity of original documents, the accuracy of copies, the genuineness of
signatures, and the legal capacity of signatories.

        We have assumed that all parties to the Merger Agreement and to any
other documents examined by us have acted, and will act, in accordance with the
terms of such Merger Agreement and documents and that the Merger will be
consummated at the Effective Time pursuant to the terms and conditions set forth
in the Merger Agreement without the waiver or modification of any such terms and
conditions. Furthermore, we
<PAGE>   2
Oberon Software Incorporated
March 3, 2000
Page 2


have assumed that all representations contained in the Merger Agreement, as well
as those representations contained in the Representation Letters, are, and at
the Effective Time will be, true and complete in all material respects, and that
any representation made in any of the documents referred to herein "to the best
of the knowledge and belief" (or similar qualification) of any person or party
is, and at the Effective Time will be, correct without such qualification. We
have also assumed that as to all matters for which a person or entity has
represented that such person or entity is not a party to, does not have, or is
not aware of, any plan, intention, understanding, or agreement, there is no such
plan, intention, understanding, or agreement. We have not attempted to verify
independently such representations, but in the course of our representation,
nothing has come to our attention that would cause us to question the accuracy
thereof.

        The conclusions expressed herein represent our judgment as to the proper
treatment of certain aspects of the Merger under the income tax laws of the
United States based upon the Code, Treasury Regulations, case law, and rulings
and other pronouncements of the Internal Revenue Service (the "IRS") as in
effect on the date of this opinion. No assurances can be given that such laws
will not be amended or otherwise changed prior to the Effective Time, or at any
other time, or that such changes will not affect the conclusions expressed
herein. Nevertheless, we undertake no responsibility to advise you of any
developments after the Effective Time in the application or interpretation of
the income tax laws of the United States.

        Our opinion represents our best judgment of how a court would decide if
presented with the issues addressed herein and is not binding upon either the
IRS or any court. Thus, no assurances can be given that a position taken in
reliance on our opinion will not be challenged by the IRS or rejected by a
court.

        This opinion addresses only the specific United States federal income
tax consequences of the Merger set forth below, and does not address any other
federal, state, local, or foreign income, estate, gift, transfer, sales, use, or
other tax consequences that may result from the Merger or any other transaction
(including any transaction undertaken in connection with the Merger). We express
no opinion regarding the tax consequences of the Merger to shareholders of
Target that are subject to special tax rules, and we express no opinion
regarding the tax consequences of the Merger arising in connection with the
ownership of options or warrants for Target stock.

        On the basis of, and subject to, the foregoing, and in reliance upon the
representations and assumptions described above, we are of the opinion that the
discussion under the section "Material United States Federal Income Tax
Consequences of the Merger" in the Registration Statement, subject to the
limitations and qualifications described therein, accurately describes the
material federal income tax considerations relevant to Target stockholders
receiving Parent Common Stock in the Merger.
<PAGE>   3
Oberon Software Incorporated
March 3, 2000
Page 3


        In rendering this opinion, we have assumed that Wilson, Sonsini,
Goodrich & Rosati has delivered, and has not withdrawn, an opinion that is
substantially similar to this one. No opinion is expressed as to any federal
income tax consequence of the Merger except as specifically set forth herein,
and this opinion may not be relied upon except with respect to the consequences
specifically discussed herein.

        This opinion is intended solely for the purpose of inclusion as an
exhibit to the Registration Statement. It may not be relied upon for any other
purpose or by any other person or entity, and may not be made available to any
other person or entity without our prior written consent. We hereby consent to
the filing of this opinion as an exhibit to the Registration Statement and
further consent to the use of our name in the Registration Statement in
connection with references to this opinion and the tax consequences of the
Merger. In giving this consent, however, we do not hereby admit that we are in
the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended.
