    to reflect the Stock Split), multiplied by 14,108,498 shares.

either company before the merger is completed. Immediately after the merger,
based upon shares outstanding as of the record date, former stockholders of
Interleaf will own approximately      % of the outstanding shares of BroadVision
common stock, and persons who were stockholders of BroadVision immediately
before the merger will own approximately      % of the outstanding shares of
BroadVision common stock immediately after the merger.

    BroadVision common stock is listed on the Nasdaq National Market under the
symbol "BVSN," and on April   , 2000, BroadVision common stock closed at $
per share.

    Stockholders of Interleaf will be asked, at Interleaf's special meeting of
stockholders, to approve the merger agreement. After careful consideration,
Interleaf's board of directors has determined that the merger and the merger
agreement are fair to you and in your best interests. Interleaf's board of
directors has approved the merger agreement and unanimously recommends its

          QUESTIONS AND ANSWERS ABOUT THE BROADVISION/INTERLEAF MERGER

Q: WHY ARE WE PROPOSING TO MERGE? (see page 37)

A: BroadVision and Interleaf are proposing to merge because we believe the
    resulting combination will create a stronger, more competitive company
    capable of achieving greater financial strength, market share, operational
    efficiencies, technology development, earning power and growth potential
    than either company would have on its own.

Q: WHAT WILL I RECEIVE IN THE MERGER? (see page 55)

A: If the merger is completed, you will receive 1.0395 shares of BroadVision
    common stock for each share of Interleaf common stock you own. For example,
    if you own 100 shares of Interleaf common stock, you will receive 103 shares
    of BroadVision common stock in exchange for your Interleaf shares and a cash
    payment equal to the value of 0.95 of a share of BroadVision common stock.
    The number of shares of BroadVision common stock to be issued for each share
    of Interleaf common stock is fixed and will not be adjusted based upon
    changes in the values of BroadVision or Interleaf common stock. As a result,
    the value of the BroadVision shares you will receive in the merger will not
    be known before the merger and will go up or down as the market price of
    BroadVision common stock goes up or down. We encourage you to obtain current
    market quotations for BroadVision and Interleaf common stock.

Q: WHAT DO I NEED TO DO NOW?

A: We urge you to read this proxy statement/prospectus carefully, including its
    annexes, and to consider how the merger affects you. Then, mail your
    completed and signed proxy card in the enclosed return envelope as soon as
    possible so that your shares can be voted at the special meeting of
    Interleaf stockholders.

Q: WHAT HAPPENS IF I DO NOT RETURN A PROXY CARD?

A: The failure to return your proxy card will have the same effect as voting
    against the merger.

Q: MAY I VOTE IN PERSON?

A: Yes. You may attend the special meeting of Interleaf stockholders and vote
    your shares in person, rather than, or in addition to, signing and returning
    your proxy card.

Q: MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A: Yes. You may change your vote at any time before your proxy card is voted at
    the special meeting. You can do this in one of three ways. First, you can
    send a written notice stating that you would like to revoke your proxy.
    Second, you can complete and submit a new proxy card. Third, you can attend
    the meeting and vote in person. Your attendance alone will not revoke your
    proxy. If you have instructed a broker to vote your shares, you must follow
    directions received from your broker to change those instructions.

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

A: Your broker will not be able to vote your shares without instructions from
    you. You should instruct your broker to vote your shares, following the
    procedure provided by your broker.

Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: No. After the merger is completed, you will receive written instructions for
    exchanging your shares of Interleaf common stock for shares of BroadVision
    common stock and a cash payment for any fractional share of BroadVision
    common stock to which you otherwise would be entitled.

DESCRIPTION OF THE MERGER (PAGE 33)

    Under the merger agreement, a wholly owned subsidiary of BroadVision will
merge with and into Interleaf. After this merger, BroadVision will own all of
the outstanding stock of Interleaf. This will

                                       3
<PAGE>
make Interleaf a wholly owned subsidiary of BroadVision. You will receive shares
of BroadVision common stock in exchange for your shares of Interleaf common
stock.

MERGER CONSIDERATION; FIXED EXCHANGE RATIO (PAGE 55)

    As an Interleaf stockholder, you will receive 1.0395 shares of BroadVision
common stock in exchange for each share of Interleaf common stock you own. The
actual number of shares you will receive in the merger will be the whole number
of shares determined by multiplying 1.0395 by the number of shares of Interleaf
common stock that you own at the effective time of the merger. You will receive
cash for any fractional share of BroadVision common stock which you otherwise
would be entitled to receive.

    The exchange ratio is fixed and, regardless of fluctuations in the market
prices of BroadVision common stock or Interleaf common stock, will not change
between now and the date that the merger is completed. Neither BroadVision nor
Interleaf has the right to terminate the merger agreement or renegotiate the
exchange ratio as a result of market price fluctuations.

COMPARATIVE PER COMMON SHARE MARKET PRICE INFORMATION (PAGE 14)

    Interleaf common stock and BroadVision common stock are both listed on the
Nasdaq National Market. On January 26, 2000, the last full trading day prior to
the public announcement of the proposed merger, Interleaf common stock closed at
$43.13 and BroadVision common stock closed at $50.69. On March 2, 2000,
Interleaf common stock closed at $83.4375 and BroadVision common stock closed at
$82.83.

TAX MATTERS (PAGE 52)

    It is a condition to the respective obligations of BroadVision and Interleaf
to consummate the merger that each company receive an opinion from its counsel
substantially to the effect that the exchange of shares of Interleaf common
stock for shares of Interleaf common stock for shares of BroadVision common
stock in the merger will be tax-free to Interleaf stockholders for federal
income tax purposes. Cash received by you instead of fractional shares of
BroadVision common stock or in exchange for Interleaf common stock pursuant to
the exercise of dissenters' rights under the Massachusetts Business Corporation
law will result in the recognition of gain or loss for federal income tax
purposes. Your tax basis in the shares of BroadVision common stock that you
receive in the merger will equal your current tax basis in your shares of
Interleaf common stock, reduced by the basis allocable to any fractional share
interest for which you receive cash.

    TAX MATTERS CAN BE COMPLICATED, AND THE TAX CONSEQUENCES OF THE MERGER TO
YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR OWN
TAX ADVISOR TO FULLY UNDERSTAND THE TAX CONSEQUENCES OF THE MERGER TO YOU.

REASONS FOR THE MERGER

BROADVISION (PAGE 38).  BroadVision's board of directors believes that
BroadVision and its stockholders would realize a number of benefits from the
merger, including, among other benefits, the following:

    - BroadVision would acquire Interleaf's XML-based content management
      solution, which BroadVision considers to be one of the broadest XML-based
      content management solutions available today;

    - the combined company would have the ability to offer complementary product
      lines and to improve BroadVision's existing product offerings;

                                       4
<PAGE>
    - BroadVision would gain access to Interleaf's technically skilled
      employees;

    - BroadVision and Interleaf would have the ability to combine technological
      resources to develop a complete Web-based business solution;

    - BroadVision would gain access to Interleaf's customer base; and

    - the combined company would have the ability to commit greater resources to
      product development efforts and fund the future growth of its business.

INTERLEAF (PAGE 39).  The Interleaf board of directors believes that Interleaf
and its stockholders would realize a number of benefits from the merger,
including, among other benefits, the following:

    - the merger would provide Interleaf with access to BroadVision's capital
      and technical resources;

    - Interleaf's stockholders would have the opportunity to participate in the
      growth potential of the combined company after the merger;

    - the combination with BroadVision would enable Interleaf to create more
      long-term value for its customers and employees;

    - the integration of Interleaf's BladeRunner family of products with
      BroadVision's One-To-One product suite would enable Interleaf to offer a
      stronger end-to-end electronic content and electronic commerce solution to
      its customers and significantly shorten the time to market for its
      products;

    - BroadVision's established relationships with large, strategic customers,
      systems integrators and other third parties, larger sales force and
      well-established distribution channels, would increase the number of
      prospective customers and distributors for Interleaf products and
      providers of Interleaf services;

    - the exchange ratio in the merger represents a premium of 39.8% over the
      closing price of Interleaf common stock for the trading day immediately
      prior to announcement of the merger and a premium of 75.4% over the
      average closing price of Interleaf common stock for the 20 trading days
      prior to the announcement of the merger; and

    - Interleaf's financial advisor, Broadview, is of the opinion that, as of
      the date of the merger agreement and subject to the conditions set forth
      in Broadview's opinion addressed to the Interleaf board of directors, the
      exchange ratio is fair, from a financial point of view, to Interleaf
      stockholders.

RECOMMENDATION OF INTERLEAF'S BOARD OF DIRECTORS (PAGE 41)

    Interleaf's board of directors believes that the merger and the merger
agreement are fair to you and in your best interests. Interleaf's board of
directors has approved the merger agreement and unanimously recommends that you
vote FOR approval of the merger agreement.

OPINION OF INTERLEAF'S FINANCIAL ADVISOR (PAGE 42)

    In deciding to approve the merger, one of the factors that the Interleaf
board of directors considered was the opinion of its financial advisor,
Broadview International LLC, that, as of January 26, 2000, the consideration to
be received by the holders of Interleaf common stock in the merger was fair to
the holders from a financial point of view. The complete Broadview opinion
letter describes the basis for its opinion and is attached as Annex D to this
proxy statement/prospectus. WE URGE YOU TO READ THE ENTIRE OPINION LETTER
CAREFULLY.

THE INTERLEAF SPECIAL MEETING OF STOCKHOLDERS (PAGE 31)

    TIME, DATE AND PLACE.  A special meeting of the stockholders of Interleaf
will be held on May   , 2000, at the principal executive offices of Interleaf
located at 62 Fourth Avenue, Waltham, Massachusetts at 8:00 a.m. local time, to
consider and approve the merger agreement.

    RECORD DATE AND VOTING POWER FOR INTERLEAF.  You are entitled to vote at the
special meeting if you owned shares of Interleaf common stock at the close of
business on April   , 2000, which is the record date for the special meeting.
You will have one vote at the special meeting for each share of Interleaf common
stock you owned at the close of business on the record date. On the record date,
there were       shares of Interleaf common stock entitled to be voted at the
special meeting.

    INTERLEAF REQUIRED VOTE.  The approval of the merger agreement requires the
affirmative vote of holders of a majority of the shares of Interleaf common
stock outstanding at the close of business on the record date.

    SHARE OWNERSHIP OF MANAGEMENT.  The directors and executive officers of
Interleaf own approximately      % of the shares of Interleaf common stock
outstanding at the close of business on the record date. All of the directors
and executive officers of Interleaf have agreed to vote their shares in favor of
the approval of the merger agreement.

INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER (PAGE 51)

    When considering the recommendation of Interleaf's board of directors that
you vote for approval of the merger agreement, you should be aware that a number
of Interleaf's officers and directors have interests in the merger that are
different from, or in addition to, yours. These interests include the following:

    - the officers of Interleaf who were granted options prior to June 1999 are
      entitled to the acceleration of these options, which will become
      exercisable in full in connection with the merger;

    - Interleaf's executive officers are entitled to severance payments in the
      event of a termination without cause or if they resign for good reason
      within 12 months of the stockholder vote approving the merger; and

    - BroadVision will ensure that indemnification and insurance arrangements
      are maintained for the Interleaf's officers and directors.

In determining the fairness of the merger to Interleaf stockholders, Interleaf's
board of directors took into account these interests.

LIMITATION ON CONSIDERING OTHER ACQUISITION PROPOSALS (PAGE 59)

    Interleaf has agreed not to approve a business combination or other similar
transaction with another party while the merger is pending, unless the other
party has made an unsolicited acquisition proposal, Interleaf's board of
directors has given notice of the acquisition proposal to BroadVision,
Interleaf's board of directors determines that it is required by its fiduciary
duties to its stockholders to consider the acquisition proposal, Interleaf's
board of directors determines that the acquisition proposal is a superior offer
and Interleaf reimburses BroadVision for certain merger expenses and pays a fee
of $30.0 million to BroadVision.

<PAGE>
TERMINATION OF THE MERGER AGREEMENT (PAGE 63)

    BroadVision and Interleaf may agree by mutual written consent to terminate
the merger agreement at any time before the merger is completed. In addition,
either company may terminate the merger agreement if:

    - the merger is not completed on or before July 31, 2000;

    - a court or government entity issues a final order prohibiting the merger;

    - the Interleaf stockholders do not approve the merger agreement; or

    - the other company materially breaches its representations, warranties or
      covenants in the merger agreement and the breach is not curable through
      the exercise of reasonable efforts or the other company is not using
      reasonable efforts to cure the breach.

    In addition, BroadVision may terminate the merger agreement if Interleaf's
board of directors takes certain actions in connection with another acquisition
proposal, fails to reaffirm its recommendation to approve the merger under
certain circumstances or fails to take certain actions in response to another
acquisition proposal, each of which is termed a "triggering event." Interleaf
may terminate the merger agreement if its board of directors approves a superior
offer.

EXPENSES AND TERMINATION FEES (PAGE 63)

    The merger agreement provides that all expenses will be paid by the party
incurring them, except for expenses related to this proxy statement/prospectus
and regulatory filings, which will be shared, and except in connection with the
termination of the merger agreement as discussed below.

    Interleaf will pay BroadVision a termination fee of $30.0 million if a
triggering event occurs, Interleaf approves, endorses or recommends, or enters
into any letter of intent or similar document or any agreement contemplating or
relating to, a superior offer or Interleaf's board of directors withdraws or
modifies its recommendation that the Interleaf stockholders vote for approval of
the merger agreement.

    In addition, if any of the above occur, or if Interleaf's stockholders fail
to approve the merger agreement, Interleaf must reimburse BroadVision for up to
$2.0 million in merger expenses, including attorneys' fees, accountants' fees,
financial advisory fees and filing fees.

    If the merger agreement is terminated because the Interleaf stockholders do
not approve the merger, and at the time of the special meeting, an acquisition
proposal previously disclosed, announced, commenced, submitted or made is still
outstanding, then Interleaf will pay to BroadVision a termination fee in the
amount of $10.0 million. If, at any time within six months from that termination
of the merger agreement, Interleaf enters into a definitive agreement or
consummates a transaction relating to that acquisition proposal, Interleaf will
pay to BroadVision an additional termination fee in the amount of
$20.0 million.

    BroadVision will pay to Interleaf a fee of $30.0 million as liquidated
damages if Interleaf terminates the merger agreement because of a breach by
BroadVision of any of its representations, warranties or covenants in the merger
agreement.

STOCK OPTION AGREEMENT (PAGE 65)

    In order for BroadVision to proceed with the merger, BroadVision required
Interleaf to grant BroadVision an option to purchase newly issued shares of
Interleaf common stock representing up to 19.9% of the number of shares of
Interleaf common stock outstanding as of January 26, 2000. The option is
exercisable only if a triggering event has occurred or the Interleaf
stockholders do not approve the merger and at the time of the special meeting a
previously disclosed acquisition proposal is

                                       8
<PAGE>
still outstanding. The option's per share exercise price is the lesser of $52.69
or 1.0395 multiplied by the average of the closing price for BroadVision common
stock on the Nasdaq National Market for the 20 consecutive trading days
preceding the date of notice of exercise. The profit that BroadVision can
recognize under the option is limited. Interleaf granted the option to
BroadVision to induce BroadVision to enter into the merger agreement. The option
could discourage other companies from trying to combine with Interleaf before
BroadVision and Interleaf complete the merger.

ANTICIPATED ACCOUNTING TREATMENT (PAGE 54)

    The merger is expected to be accounted for as a purchase.

DISSENTERS' RIGHTS (PAGE 76)

    Interleaf stockholders will be entitled to dissenters' rights if the
stockholders satisfy all applicable legal procedures and requirements set forth
in the Massachusetts Business Corporation Law.

</TABLE>

    The estimated equivalent per share price of a share of Interleaf common
stock equals the exchange ratio of 1.0395 multiplied by the price of a share of
BroadVision common stock. You may use this calculation to determine what your
shares of Interleaf common stock will be worth if the merger is completed. If
the merger had occurred on March 2, 2000, you would have received 1.0395 shares
of BroadVision common stock, worth a total of $86.10, for each share of
Interleaf common stock you owned. The actual equivalent per share price of a
share of Interleaf common stock that you will receive if the merger closes may
be different from this price because the per share price of BroadVision common
stock fluctuates.

    Neither BroadVision nor Interleaf has ever declared or paid cash dividends
on its common stock. The policies of BroadVision and Interleaf are to retain
earnings for use in its business. Following the merger, BroadVision common stock
will continue to be listed on Nasdaq and there will be no further market for the
Interleaf common stock.

          SELECTED UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

    For pro forma purposes, BroadVision's consolidated statement of operations
for the fiscal year ended December 31, 1998 and the unaudited consolidated
statement of operations for the nine months ended September 30, 1999 have been
combined with the consolidated statement of operations of Interleaf for the
fiscal year ended March 31, 1999 and the unaudited consolidated statement of
operations for the nine months ended December 31, 1999, which dates end within
90 days of the BroadVision fiscal year end and interim reporting period,
respectively. In addition, BroadVision's unaudited consolidated balance sheet as
of September 30, 1999 has been combined with Interleaf's unaudited consolidated
balance sheet as of September 30, 1999. This selected unaudited pro forma
combined financial information should be read in conjunction with the separate
historical financial statements and accompanying notes of BroadVision and
Interleaf, which are incorporated by reference in this proxy
statement/prospectus. For a list of the BroadVision and Interleaf filings
incorporated by reference in this proxy statement/prospectus, we refer you to
the section entitled "Where You Can Find More Information" in this proxy
statement/prospectus. The unaudited pro forma combined financial data set forth
below do not reflect any cost savings anticipated as a result of the merger. You
should not rely on the selected unaudited pro forma combined financial
information as an indication of the results of operations or financial position
that would have been achieved if the merger had taken place earlier or of the
results of operations or financial position of BroadVision after completion of
the merger.

</TABLE>

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

(1) Basic income (loss) per share is computed using the weighted average number
    of common shares outstanding during the period. Diluted income (loss) per
    share is computed using the weighted average number of common and common
    equivalent shares outstanding during the period. Common equivalent shares
    consist of the shares issuable upon the exercise of stock options and
    warrants. Common equivalent shares are excluded from the computations if
    their effect is antidilutive.

(2) The historical book value per BroadVision share is computed by dividing
    stockholders' equity by the number of shares of common stock outstanding at
    September 30, 1999 and December 31, 1998. The historical book value per
    Interleaf share is computed by dividing stockholders' equity by the number
    of shares of common stock outstanding at December 31, 1999 and March 31,
    1999. The pro forma combined book value per BroadVision share is computed by
    dividing pro forma stockholders' equity by the pro forma number of shares of
    BroadVision common stock outstanding as of September 30, 1999, assuming the
    merger had occurred as of that date.

(3) The equivalent combined pro forma loss and book value per Interleaf share is
    calculated by dividing the combined pro forma share amounts by the exchange
    ratio of 1.0395 shares of BroadVision common stock for each share of
    Interleaf common stock.

                                  RISK FACTORS

    By voting to approve the merger agreement, you will be choosing to invest in
BroadVision common stock. When you decide whether to vote for approval of the
merger agreement, you should consider the following factors in conjunction with
the other information included or incorporated by reference in this proxy
statement/prospectus.

                          RISKS RELATING TO THE MERGER

YOU WILL RECEIVE A FIXED NUMBER OF SHARES OF BROADVISION COMMON STOCK IN THE
MERGER, NOT A FIXED VALUE.

    Upon completion of the merger, each of your Interleaf shares will be
converted into 1.0395 shares of BroadVision common stock. This exchange ratio is
fixed and the merger agreement neither provides for any adjustments in the
exchange ratio nor affords any termination rights to either Interleaf or
BroadVision, based solely on fluctuations in the price of BroadVision common
stock. Accordingly, the number of shares that Interleaf stockholders will
receive in the merger will not change, even if the market price of BroadVision
common stock changes. Recently the stock market and, in particular, the
securities of technology companies have experienced extreme price and volume
fluctuations. These market fluctuations may adversely affect the market price of
BroadVision common stock. The market price of BroadVision common stock upon and
after completion of the merger could be lower than the market price on the date
of the merger agreement or the current market price. You should obtain recent
market quotations for BroadVision common stock before you vote on the merger.

IF BROADVISION AND INTERLEAF ARE NOT SUCCESSFUL IN INTEGRATING THEIR
ORGANIZATIONS, THE COMBINED COMPANY WILL BE UNABLE TO OPERATE EFFICIENTLY AFTER
THE MERGER.

    The combined company's ability to realize the anticipated benefits of the
merger will depend in part on the integration of BroadVision's and Interleaf's
operations, products and personnel in a timely and efficient manner. In order
for the combined company to provide enhanced and more valuable products to its
customers after the merger, the combined company will need to integrate its
product development operations and product lines. This integration may be
difficult and unpredictable because BroadVision's products and Interleaf's
products are highly complex, have been developed independently and were designed
without regard to integration. Successful integration of the two companies'
product development operations and product lines also requires coordination of
different development and engineering teams, as well as sales and marketing
efforts and personnel. This, too, may be difficult and unpredictable because of
possible cultural conflicts between BroadVision and Interleaf and different
product and technology decisions. If the two companies cannot successfully
integrate their operations, products and personnel, BroadVision and Interleaf
may not realize the expected benefits of the merger.

EFFORTS TO INTEGRATE BROADVISION AND INTERLEAF MAY DIVERT MANAGEMENT'S ATTENTION
AWAY FROM DAY-TO-DAY OPERATIONS.

    The integration of BroadVision's and Interleaf's operations, products and
personnel may place a significant burden on the combined company's management
and other internal resources. The diversion of management attention and any
difficulties encountered in the transition and integration process could prevent
the combined company from operating efficiently.

BROADVISION EXPECTS TO INCUR SIGNIFICANT COSTS TO INTEGRATE THE COMPANIES INTO A
SINGLE BUSINESS.

    BroadVision expects to incur costs from integrating Interleaf's operations,
products and personnel. These costs may be significant and may include expenses
and other liabilities for:

    - employee redeployment, relocation or severance;

    - conversion of information systems;

                                       16
<PAGE>
    - combining teams and processes in various functional areas; and

    - reorganization or closures of facilities.

The integration costs incurred by BroadVision may negatively impact the
financial condition of the combined company and the market price of
BroadVision's stock.

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

    The successful combination of BroadVision and Interleaf will depend in part
on the retention of personnel critical to the business and operations of the
combined company due to, for example, unique technical skills or management
expertise. BroadVision may be unable to retain BroadVision and Interleaf
management, technical, sales and customer support personnel that are critical to
the successful integration of BroadVision and Interleaf, resulting in disruption
of operations, loss of key information, expertise or know-how and unanticipated
additional recruitment and training costs and otherwise diminishing anticipated
benefits of the merger.

FAILURE TO COMPLETE THE MERGER COULD CAUSE INTERLEAF'S STOCK PRICE TO DECLINE.

    If the merger is not completed for any reason, Interleaf's stock price may
decline due to any or all of the following potential consequences:

    - Interleaf may become obligated to pay BroadVision up to $2.0 million in
      merger-related expenses plus a termination fee of up to $30.0 million;

    - the option Interleaf granted to BroadVision to purchase up to 19.9% of the
      number of shares of Interleaf common stock outstanding as of January 26,
      2000 may become exercisable at a price below the then prevailing market
      price of Interleaf's common stock, creating both the potential for
      dilution to the equity interests of certain existing stockholders and
      possible impediments to an alternative transaction.;

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

    - Interleaf may have difficulty in retaining its key management, technical
      and sales personnel.

    In addition, if the merger is not completed, Interleaf's stock price may
decline to the extent that the current market price of Interleaf common stock
reflects a market assumption that the merger will be completed. If the merger is
not completed and Interleaf's board of directors determines to seek another
business combination, we may be unable to find a partner willing to pay an
equivalent or more attractive price than that which BroadVision will pay in the
merger, which could further depress Interleaf's stock price.

SALES OF BROADVISION AND INTERLEAF PRODUCTS COULD DECLINE IF CUSTOMER
RELATIONSHIPS ARE DISRUPTED BY THE MERGER.

    The merger may have the effect of disrupting customer relationships.
BroadVision and Interleaf customers may not continue their current buying
patterns during the pendency of, and following, the merger. Customers may defer
purchasing decisions as they evaluate the likelihood of successful integration
of BroadVision's and Interleaf's products and the combined company's future
product strategy. Customers of BroadVision may want the functionality of
Interleaf's products but may not want to purchase Interleaf's products.
Similarly, customers of Interleaf may want the functionality of BroadVision's
products but may not want to purchase BroadVision's products. For these and
other reasons, customers of BroadVision or Interleaf may instead purchase
products of competitors. In addition, by increasing the breadth of BroadVision's
and Interleaf's business, the merger may make it more difficult for the combined
company to enter into relationships with customers and strategic

                                       17
<PAGE>
partners, some of whom may view the combined company as a more direct competitor
than either BroadVision or Interleaf as an independent company. Any significant
delay or reduction in orders for BroadVision's or Interleaf's products could
cause sales of the combined company's products to decline.

INTERLEAF HAS DISCONTINUED DEVELOPMENT OF ITS WEB-SERVER PRODUCT IN FAVOR OF A
RESELLER ARRANGEMENT WITH BROADVISION UNDER WHICH INTERLEAF WILL INTEGRATE
BLADERUNNER WITH BROADVISION ONE-TO-ONE ENTERPRISE. IF THE INTEGRATION DOES NOT
OCCUR AS PLANNED, INTERLEAF'S REVENUES MAY SUFFER.

    In connection with the merger, on February 18, 2000 Interleaf entered into
an arm's length reseller agreement with BroadVision under which Interleaf has
the worldwide right to market and license the BroadVision One-to-One Enterprise
product for a term of two years. Interleaf had previously announced the
development of BR-Web, a Web-facing server for the delivery of content over the
Internet, originally scheduled for release in March 2000. BroadVision One-to-One
Enterprise currently provides the functionality planned to be included in
BR-Web. Because Interleaf believes that the integration of BladeRunner and
BroadVision One-to-One will enable Interleaf to offer a stronger solution to
customers and significantly shorten its time to market with a more
comprehensive, integrated product, Interleaf has discontinued development of
BR-Web and is instead working to integrate BladeRunner with BroadVision
One-to-One.

    Interleaf plans to complete the initial integration of BladeRunner and
BroadVision One-to-One by the end of March 2000 and to offer the combined
product for sale to customers in the current quarter as a replacement for
BR-Web. However, the integration may not proceed as planned if Interleaf
encounters difficulties in development and incompatibilities between the two
products. In that event, Interleaf may be unable to sell BladeRunner to
customers who require the BR-Web functionality, and its revenues may suffer as a
result.

    Interleaf will depend on BroadVision to provide upgrades, support, training
and assistance in promoting and implementing the BroadVision One-to-One product.
If BroadVision fails to perform its obligations under the reseller agreement,
Interleaf may be forced to re-initiate the development of BR-Web, which would
result in significant costs and a significant increase in the overall time to
market of its Web-server product.

THE COMBINED COMPANY'S ABILITY TO REALIZE EXPECTED REVENUES DEPENDS ON THE
SUCCESSFUL MARKETING AND SALE OF INTERLEAF'S CURRENT XML-BASED PRODUCTS AND OUR
SUCCESSFUL INTRODUCTION OF NEW XML-BASED PRODUCTS.

    Upon completion of the merger, the combined company will expect to derive
significant revenues from the license of, and services and support for, the
BladeRunner family of products. Market acceptance of BladeRunner depends upon
the continued growth of the market for products based on eXtensible Markup
Language, or XML, and continued customer demand for the specific functionality
of the BladeRunner products, either of which may not occur. The combined company
will expect to realize revenues from planned future BladeRunner releases,
including BladeRunner 2.0, components and products currently in development and
testing, such as Interleaf's XML Wireless Application Product known as X-WAP,
and related products that the combined company will expect to develop.

    BladeRunner 2.0 and X-WAP currently are being developed by Interleaf and are
designed for new market opportunities. Accordingly, there are significant risks
associated with their introduction. For example, the combined company may
encounter the following:

    - difficulties associated with the timely development and introduction of
      products;

    - a lack of existing or sustainable markets for these products, once
      introduced, or for complementary products, such as Web-enabled wireless
      devices;

    - unanticipated difficulties with the ability of these products to handle
      the simultaneous processing of a greater volume of transactions, while
      maintaining required levels of performance;

                                       18
<PAGE>
    - changes in XML and the related eXtensible Style Language, or XSL, that
      would require the combined company to redesign or modify these products,
      resulting in higher costs, additional delays and performance degradation;

    - the emergence of new standard programming languages or competing
      technologies that could render XML and Interleaf's products obsolete;

    - the development of similar XML-based products by other companies that
      could diminish the demand for these products; and

    - undetected flaws in these products that may not become apparent until
      after the products are introduced, resulting in product returns, damage to
      the combined company's reputation, loss of revenues and increased service
      and redevelopment costs.

If any of these products in development are delayed or, upon introduction, fail
to meet customer needs or expectations for any reason, the combined company
could suffer a loss of reputation, a market may not develop for the products or
the combined company may be forced to provide software modifications, upgrades
or enhancements, which could be costly and time consuming. As a result,
BroadVision and Interleaf may not realize expected revenues from the sale and
servicing of new BladeRunner products.

CERTAIN REGULATORY AGENCIES MUST APPROVE THE MERGER AND COULD IMPOSE CONDITIONS
ON, DELAY OR REFUSE TO APPROVE THE MERGER.

    To complete the merger, BroadVision and Interleaf must obtain approvals or
consents from certain federal regulatory commissions and other government
agencies. These agencies may seek to impose conditions on BroadVision or
Interleaf before giving their approval or consent, and those conditions could
harm the combined company's business. In addition, a delay in obtaining the
requisite regulatory approvals will delay the completion of the merger. The
companies may be unable to obtain the required regulatory approvals, or obtain
them within the time frame contemplated in the merger agreement.

                         RISKS RELATING TO BROADVISION

FLUCTUATIONS IN BROADVISION'S QUARTERLY OPERATING RESULTS MAY CAUSE
BROADVISION'S STOCK PRICE TO DECLINE AND MAKE IT DIFFICULT FOR BROADVISION TO
FORECAST QUARTERLY REVENUE AND OPERATING RESULTS.

    BroadVision's quarterly operating results have in the past fluctuated and
may in the future fluctuate significantly as a result of a variety of factors,
many of which are outside of BroadVision's control. It is likely that
BroadVision's operating results in one or more future quarters may be below the
expectations of securities analysts and investors. In that event, the trading
price of the common stock of BroadVision almost certainly would decline.

    Factors that may affect BroadVision's quarterly operating results include
the following:

    - the timing of introductions or enhancements of products and services of
      BroadVision or its competitors;

    - timing of receipt and fulfillment of significant orders;

    - market acceptance of new products;

    - the mix of products sold by BroadVision;

    - changes in pricing policies by BroadVision or its competitors;

    - changes in BroadVision's sales incentive plans;

                                       19
<PAGE>
    - the budgeting cycles of BroadVision's customers;

    - customer order deferrals in anticipation of new products or enhancements
      by BroadVision or its competitors;

    - nonrenewal of BroadVision's service agreements (which generally
      automatically renew for one-year terms unless earlier terminated by either
      party upon 90-days notice);

    - product life cycles;

    - changes in strategy;

    - seasonal trends;

    - the mix of distribution channels through which BroadVision's products are
      sold;

    - the mix of international and domestic sales;

    - the rate at which new sales people become productive; and

    - changes in the level of operating expenses to support projected growth.

    Due to these and other factors, it is difficult to accurately forecast the
quarterly revenues and operating results of BroadVision. BroadVision believes
that period-to-period comparisons of the company's operating results may not be
meaningful and you should not rely upon them as any indication of future
performance for BroadVision.

BROADVISION'S SUCCESS IS SUBSTANTIALLY DEPENDENT ON REVENUES FROM ITS
BROADVISION ONE-TO-ONE ENTERPRISE PRODUCT SUITE AND RELATED SERVICES.

    To date, substantially all of BroadVision's revenues have been attributable
to license sales of the BroadVision One-To-One Enterprise product and related
packaged application products and associated services. BroadVision currently
expects these products and services to account for most of its future revenues.
The inability of BroadVision's customers to successfully develop and deploy an
online marketplace using BroadVision One-To-One application products could
damage BroadVision's reputation and cause a loss of customers. In addition,
factors negatively affecting the pricing of or demand for the BroadVision
One-To-One application products, such as increased competition or rapid
technological change, could cause BroadVision's revenues to decline.

BROADVISION'S FUTURE FINANCIAL PERFORMANCE IS LARGELY DEPENDENT ON THE
SUCCESSFUL UPGRADING OF ITS CURRENT PRODUCTS AND INTRODUCTION OF NEW PRODUCTS.

    BroadVision's future financial performance will depend, in significant part,
on the successful development and sale of new and enhanced versions of its
BroadVision One-To-One application products and other new products. BroadVision
may be unable to upgrade and continue to market the BroadVision One-To-One
application products. BroadVision may be unable to successfully develop new
products and new products may not achieve market acceptance.

BROADVISION'S LENGTHY SALES AND PRODUCT IMPLEMENTATION CYCLES COULD CAUSE DELAYS
IN REVENUE RECOGNITION AND MAKE IT DIFFICULT TO PREDICT THE COMPANY'S QUARTERLY
RESULTS.

    BroadVision's sales and product implementation cycles are subject to delays
over which it has little or no control. These delays can affect the timing of
revenue recognition and make it difficult to predict BroadVision's quarterly
results. Licensing the BroadVision One-to-One application products is often an
enterprise-wide decision by prospective customers. The importance of this
decision requires that BroadVision engage in a lengthy sales cycle with
prospective customers. During the sales process, BroadVision provides a
significant level of education regarding the uses and benefits of its products.

                                       20
<PAGE>
Once the decision has been made to implement its products, BroadVision's
customers or its Worldwide Professional Services Organization consultants then
must commit significant resources over an extended period of time. Delays in
license transactions due to unusually lengthy sales cycles could cause
BroadVision's operating results to vary significantly from quarter to quarter.

THE MARKET FOR BROADVISION'S PRODUCTS AND SERVICES IS IN ITS EARLY STAGES OF
DEVELOPMENT AND MAY FAIL TO MATURE INTO A SUSTAINABLE MARKET.

    BroadVision's products and services facilitate online commerce and
communication over public and private networks. The market for these products
and services is in its early stages of development and is rapidly evolving. A
viable market may fail to emerge or be sustainable. BroadVision cannot predict
the level of demand for and market acceptance of its products and services,
especially because acquisition of its products and services requires a large
capital or other significant resource commitment. If the market for
BroadVision's products and services does not continue to mature, BroadVision
will be unable to execute successfully its business plan.

    Adoption of electronic commerce and knowledge management, particularly by
those individuals and companies that have historically relied upon traditional
means of commerce and communication, will require a broad acceptance of new and
different methods of conducting business and exchanging information.
BroadVision's future revenues and profits will substantially depend on the
Internet being accepted and widely used for commerce and communication. If
Internet commerce does not continue to grow or grows more slowly than expected,
BroadVision's future revenues and profits may not meet its expectations or those
of analysts. In the emerging marketplace of Internet commerce, BroadVision's
products and services involve a new approach to the conduct of online business.
As a result, intensive marketing and sales efforts may be necessary to educate
prospective customers regarding the uses and benefits of its products and
services, thereby generating demand. Companies that have already invested
substantial resources in other methods of conducting business may be reluctant
to adopt a new approach that may replace, limit or compete with their existing
systems. Similarly, purchasers with established patterns of commerce may be
reluctant to alter those patterns or may otherwise resist providing the personal
data necessary to support BroadVision's consumer profiling capability. In
addition, the security and privacy concerns of existing and potential online
purchasers may inhibit the growth of online business generally and the market's
acceptance of its products and services in particular. Accordingly, a viable
market for BroadVision's products and services may not emerge or be sustainable.

A BREACH OF THE ENCRYPTION TECHNOLOGY THAT BROADVISION USES COULD EXPOSE THE
COMPANY TO LIABILITY AND HARM ITS REPUTATION, CAUSING A LOSS OF CUSTOMERS.

    If any breach of the security technology embedded in BroadVision's products
were to occur, the company would be exposed to liability and its reputation
could be harmed, which could cause BroadVision to lose customers. A significant
barrier to online commerce and communication is the secure exchange of valuable
and confidential information over public networks. BroadVision relies on
encryption and authentication technology, including public key cryptography
technology licensed from RSA Security Inc., to provide the security and
authentication necessary to effect the secure exchange of confidential
information. Advances in computer capabilities, new discoveries in the field of
cryptography or other events or developments could cause a breach of the RSA or
other algorithms that BroadVision uses to protect customer transaction data.

BROADVISION'S PRODUCTS ARE ESPECIALLY SUSCEPTIBLE TO PRODUCT DEFECTS BECAUSE
THEY ARE COMPLEX.

    Sophisticated software products, like those sold by BroadVision, may contain
undetected errors that will not become apparent until after the products are
introduced or when the volume of provided services increases. It is possible
that, despite testing by BroadVision and prospective customers, errors

                                       21
<PAGE>
will be found in its products. Product defects could result in all or any of the
following consequences to BroadVision's business:

    - loss of revenues;

    - delay in market acceptance;

    - diversion of development resources;

    - damage to its reputation; or

    - increased service and warranty costs.

BROADVISION IS CONTINUING TO SUBSTANTIALLY EXPAND ITS BUSINESS AND OPERATIONS
AND WILL NEED TO MANAGE AND SUPPORT THIS EXPANSION EFFECTIVELY IN ORDER FOR ITS
BUSINESS PLAN TO SUCCEED.

    BroadVision has substantially expanded its business and operations since its
inception in 1993. BroadVision expects to continue to experience periods of
rapid change. If BroadVision is unable to support this growth effectively, it
will have to divert additional resources away from executing its business plan
and toward internal administration. BroadVision's past expansion has placed, and
any future expansion is expected to place, significant demands on its
administrative, operational, financial and other resources. BroadVision expects
operating expenses and staffing levels to increase substantially in the future.
In particular, BroadVision intends to continue hiring a significant number of
additional personnel this year and in later years. BroadVision also expects to
expend resources on expanding accounting and internal management systems and
implementing a variety of new systems and procedures. If its revenues do not
increase in proportion to its operating expenses, its management systems do not
expand to meet increasing demands or the company's management otherwise fails to
support its expansion effectively, BroadVision's business plan may not succeed.

BROADVISION IS DEPENDENT ON DIRECT SALES PERSONNEL AND THIRD-PARTY DISTRIBUTION
CHANNELS TO ACHIEVE REVENUE GROWTH.

    To date, BroadVision has sold its products primarily through its direct
sales force. BroadVision's ability to achieve significant revenue growth in the
future largely will depend on its success in recruiting and training sufficient
direct sales personnel and establishing and maintaining relationships with
distributors, resellers and systems integrators. BroadVision's products and
services require a sophisticated sales effort targeted at the senior management
of its prospective customers. New hires as well as employees of BroadVision's
distributors, resellers and systems integrators require training and take time
to achieve full productivity. BroadVision's recent hires may not become as
productive as necessary, and BroadVision may be unable to hire sufficient
numbers of qualified individuals in the future. BroadVision has entered into
strategic alliance agreements with partners, including Hewlett-Packard Company,
Sema Group and Security First Network Bank, under which these partners have
agreed to resell and

                                       22
<PAGE>
support BroadVision's current BroadVision One-to-One product suite. These
contracts are generally terminable by either party upon 30 days' notice of an
uncured material breach. Termination of the Hewlett-Packard, Sema, Security
First or other similar alliances could harm BroadVision's expected revenues.
BroadVision may be unable to expand its other distribution channels, and any
expansion may not result in revenue increases. If BroadVision fails to expand
its direct sales force or other distribution channels, its revenues may not grow
or they may decline.

BROADVISION'S CUSTOMERS MAY RELY ON THIRD-PARTY SYSTEMS INTEGRATORS FOR THE
SUCCESS OF ONLINE MARKETPLACES.

    BroadVision's current and prospective customers may rely on third-party
systems integrators to develop, deploy and manage online marketplaces. If
BroadVision is unable to adequately train these systems integrators who, as a
result, ineffectively assist customers with their online marketplaces,
BroadVision's reputation may be harmed and it may lose customers. In addition,
if for any reason a large number of these integrators adopt a different product
or technology instead of the BroadVision One-To-One application products, sales
of these products may not grow or they may decline.

BROADVISION IS SUSCEPTIBLE TO NUMEROUS RISKS ASSOCIATED WITH INTERNATIONAL
OPERATIONS.

    BroadVision's international activities expose BroadVision to numerous
additional risks. In the year ended December 31, 1999, approximately 31% of
BroadVision's revenues were derived from sales outside of North America.
BroadVision has ten offices in Europe and Asia and one office in Australia. A
key component of BroadVision's business strategy is to expand its international
activities. Reflecting BroadVision's commitment to a significant international
presence, BroadVision listed its shares of common stock on the Neuer Markt
segment of the Frankfurt Stock Exchange beginning on November 3, 1999. As
BroadVision continues to expand internationally, it will be increasingly subject
to risks of doing business internationally, including:

    - unexpected changes in regulatory requirements;

    - export controls relating to encryption technology and other export
      restrictions;

    - tariffs and other trade barriers;

    - difficulties in staffing and managing foreign operations;

    - political and economic instability;

    - fluctuations in currency exchange rates;

    - reduced protection for intellectual property rights in some countries;

    - cultural barriers;

    - seasonal reductions in business activity during the summer months in
      Europe and certain other parts of the world; and

    - potentially adverse tax consequences.

    BroadVision's international sales growth will be limited if it is unable to
establish additional foreign operations, expand international sales channel
management and support, hire additional personnel, customize products for local
markets and develop relationships with international service providers,
distributors and system integrators. Even if BroadVision is able to successfully
expand its international operations, BroadVision may not succeed in maintaining
or expanding international market demand for its products.

                                       23
<PAGE>
BROADVISION'S SUCCESS AND COMPETITIVE POSITION WILL DEPEND ON ITS ABILITY TO
PROTECT ITS PROPRIETARY TECHNOLOGY.

    It will be essential to the success of BroadVision's business that it
adequately protect its proprietary technology. Although BroadVision holds a U.S.
patent, issued in January 1998, on elements of the BroadVision One-To-One
Enterprise product, this patent may not provide an adequate level of
intellectual property protection. BroadVision also relies on copyright, trade
secret and trademark law to protect its technology. BroadVision has registered
"BroadVision" and "BroadVision One-To-One" as trademarks in the United States.
It is possible that BroadVision's competitors or other companies will adopt
product names similar to these trademarks, impeding BroadVision's ability to
build brand identity and possibly confusing customers. BroadVision provides its
products to end users generally under nonexclusive, nontransferable licenses
during the term of the relevant agreement, which is usually in perpetuity.
BroadVision makes the source code available for some portions of its products.
BroadVision protects the source code for its proprietary software both as a
trade secret and as a copyrighted work. However, disclosing the source code may
increase the likelihood of third-party misappropriation.

    As a matter of company policy, BroadVision enters into confidentiality and
assignment agreements with its employees, consultants and vendors. BroadVision
also controls access to and distribution of its software, documents and other
proprietary information. Notwithstanding these precautions, it may be possible
for an unauthorized third party to copy or otherwise obtain and use its software
or other proprietary information or to develop similar software independently.
Policing unauthorized use of BroadVision's products will be difficult,
particularly because the global nature of the Internet makes it difficult to
control the ultimate destination or security of software and other transmitted
data. The laws of other countries may afford BroadVision little or no effective
protection of its intellectual property. The steps BroadVision has taken to
prevent misappropriation of its technology, including entering into agreements
for that purpose, may be insufficient. In addition, litigation may be necessary
in the future to enforce BroadVision's intellectual property rights, to protect
its trade secrets, to determine the validity and scope of the proprietary rights
of others or to defend against claims of infringement or invalidity. Litigation
like this, whether successful or unsuccessful, could result in substantial costs
and diversions of BroadVision's management resources, either of which could harm
its business.

BROADVISION WILL BE SUBJECT TO CLAIMS OF INTELLECTUAL PROPERTY INFRINGEMENT,
WHICH COULD DIVERT MANAGEMENT RESOURCES, CAUSE PRODUCT DELAYS OR REQUIRE THAT
BROADVISION ENTER INTO LICENSING OR ROYALTY AGREEMENTS.

    Third parties may claim that BroadVision has infringed their patent,
trademark, copyright or other proprietary rights. It is also possible that
claims will be made for indemnification resulting from allegations of
infringement. In addition, intellectual property infringement claims may be
asserted against BroadVision as a result of the use by BroadVision, its
customers or other third parties of its products for the transmission,
dissemination or display of information on the Internet. Any claims, with or
without merit, could be time consuming, costly, cause product shipment delays or
require that BroadVision enter into royalty or licensing agreements. These
licenses might not be available on reasonable terms, or at all.

THE LOSS OR MALFUNCTION OF TECHNOLOGY LICENSED FROM THIRD PARTIES COULD DELAY
THE INTRODUCTION OF BROADVISION'S PRODUCTS AND SERVICES.

    BroadVision relies in part on technology that it licenses from third
parties, including relational database management systems from Sybase, object
request broker software from IONA Technologies PLC, database access technology
from Rogue Wave Software Inc. and other software. BroadVision integrates or
sublicenses this technology with internally developed software to perform key
functions. For example, BroadVision's products and services incorporate data
encryption and authentication technology licensed from RSA. Third-party
technology licenses might not continue to be available to BroadVision on
commercially reasonable terms, or at all. Moreover, the licensed technology may

                                       24
<PAGE>
contain defects that BroadVision cannot control. The loss of any of these
technology licenses could cause delays in introducing BroadVision's products or
services until equivalent technology, if available, is identified, licensed and
integrated. Delays in introducing BroadVision's products and services could harm
its business.

    BROADVISION'S EXECUTIVE OFFICERS, KEY EMPLOYEES AND HIGHLY SKILLED TECHNICAL
AND MANAGERIAL PERSONNEL ARE CRITICAL TO ITS BUSINESS, AND THEY MAY NOT REMAIN
WITH BROADVISION IN THE FUTURE.

    BroadVision's performance will substantially depend on the performance of
its executive officers and key employees. BroadVision also will rely on its
ability to retain and motivate qualified personnel, especially its management
and highly skilled development teams. The loss of the services of any of its
executive officers or key employees, particularly its founder and Chief
Executive Officer, Dr. Pehong Chen, could cause BroadVision to incur increased
operating expenses and divert senior management resources in searching for
replacements. The loss of their services also could harm BroadVision's
reputation if its customers were to become concerned about BroadVision's future
operations. BroadVision does not carry "key person" life insurance policies on
any of its employees. BroadVision's future success also depends on its
continuing ability to identify, hire, train and retain other highly qualified
technical and managerial personnel. Competition for these personnel is intense,
especially in the Internet industry. BroadVision has in the past experienced and
will continue to experience difficulty in hiring and retaining sufficient
numbers of highly skilled employees.

CURRENT AND POTENTIAL COMPETITORS COULD MAKE IT DIFFICULT FOR BROADVISION TO
ACQUIRE AND RETAIN CUSTOMERS NOW AND IN THE FUTURE.

    If BroadVision fails to compete successfully with current or future
competitors, BroadVision may lose market share. The market for e-business
solutions is rapidly evolving and intensely competitive. BroadVision's
customers' requirements and the technology available to satisfy those
requirements will continually change. BroadVision expects competition in this
market to persist and increase in the future. BroadVision's primary competition
currently includes:

    - in-house development efforts by prospective customers or partners;

    - other vendors of application software or application development platforms
      and tools directed at interactive commerce and financial services, such as
      Art Technology Group Inc., InterWorld Corporation, Open Market, Inc. and
      Vignette Corporation;

    - Web content developers that develop custom software or integrate other
      application software into custom solutions;

    - International Business Machines Corporation; and

    - Microsoft Corporation.

    Compared to BroadVision, many of these and other current and future
competitors have longer operating histories and significantly greater financial,
technical, marketing and other resources than those of BroadVision. As a result,
they may be able to respond more quickly to new or changing opportunities,
technologies and customer requirements. Many of these companies also can use
their greater name recognition and more extensive customer base to gain market
share at BroadVision's expense. Competitors may be able to undertake more
extensive promotional activities, adopt more aggressive pricing policies and
offer more attractive terms to purchasers. Current and potential competitors may
bundle their products to discourage users from purchasing BroadVision's
products. In addition, competitors have established or may establish cooperative
relationships among themselves or with third parties to enhance their products.
Accordingly, it is possible that new competitors or alliances among competitors
may emerge and rapidly acquire significant market share. Competitive pressures
may make it difficult for BroadVision to acquire and retain customers and may
require

                                       25
<PAGE>
BroadVision to reduce the price of its products. BroadVision may be unable to
compete successfully with current or new competitors.

LIMITATIONS ON THE ONLINE COLLECTION OF PROFILE INFORMATION COULD IMPAIR THE
EFFECTIVENESS OF BROADVISION'S PRODUCTS.

    Online users' resistance to providing personal data and laws and regulations
prohibiting use of personal data gathered online without express consent or
requiring businesses to notify their Web site visitors of the possible
dissemination of their personal data could limit the effectiveness of
BroadVision's products. One of the principal features of the BroadVision
One-To-One application products is the ability to develop and maintain profiles
of online users to assist business managers in determining the nature of the
content to be provided to these online users. Typically, profile information is
captured when consumers, business customers and employees visit a Web site and
volunteer information in response to survey questions concerning their
backgrounds, interests and preferences. Profiles can be augmented over time
through the subsequent collection of usage data. Although BroadVision One-To-One
products are designed to enable the development of applications that permit Web
site visitors to prevent the distribution of any of their personal data beyond
that specific Web site, privacy concerns may nevertheless cause visitors to
resist providing the personal data necessary to support this profiling
capability. The mere perception by prospective customers that substantial
security and privacy concerns exist among online users, whether or not valid,
may indirectly inhibit market acceptance of BroadVision's products. In addition,
new laws and regulations could heighten privacy concerns by requiring businesses
to notify Web site users that the data captured from them while online may be
used by marketing entities to direct product messages to them. While BroadVision
is not aware of any laws or regulations like this currently in effect or in
development in the United States, other countries and political entities,
including the European Union and its member states, have adopted legal
requirements imposing restrictions on the collection, use and processing of
personal data. It is possible that similar legal requirements could be adopted
in the United States. If the privacy concerns of consumers are not adequately
addressed, the effectiveness of the BroadVision One-to-One application products
could be impaired.

IF BROADVISION IS UNABLE TO MEET THE RAPID TECHNOLOGICAL CHANGES IN ONLINE
COMMERCE AND COMMUNICATION, ITS PRODUCTS AND SERVICES MAY FAIL TO BE
COMPETITIVE.

    BroadVision's products and services may fail to be competitive if
BroadVision does not maintain or exceed the pace of technological developments
in Internet commerce and communication. The information services, software and
communications industries are characterized by rapid technological change,
changes in customer requirements, frequent new product and service introductions
and enhancements and evolving industry standards and practices. The introduction
of products and services embodying new technologies and the emergence of new
industry standards and practices can render existing products and services
obsolete. BroadVision's future success will depend, in part, on its ability to:

    - develop leading technologies;

    - enhance its existing products and services;

    - develop new products and services that address the increasingly
      sophisticated and varied needs of its prospective customers; and

    - respond to technological advances and emerging industry standards and
      practices on a timely and cost-effective basis.

    Internet commerce technology is complex and new products and enhancements
can require long development periods. If BroadVision is unable to develop and
introduce new products and services or

                                       26
<PAGE>
enhancements in a timely manner in response to changing market conditions or
customer requirements, or if new products and services do not achieve market
acceptance, BroadVision's business may fail to be competitive.

NEW AND EXISTING LAWS COULD EITHER DIRECTLY RESTRICT BROADVISION'S BUSINESS OR
INDIRECTLY AFFECT ITS BUSINESS BY LIMITING THE GROWTH OF INTERNET COMMERCE.

    The adoption of any laws or regulations that restrict BroadVision's methods
of doing business or limit the growth of the Internet could decrease demand for
its products and services and increase its cost of doing business. Today, there
are relatively few laws specifically directed towards online services. However,
due to the increasing popularity of the Internet generally and Internet commerce
specifically, BroadVision expects that federal, state or foreign agencies will
enact laws and regulations with respect to the Internet. These new laws and
regulations would be likely to address issues like online user privacy, pricing,
content and quality of products and services. If enacted, these laws and
regulations could limit the market for BroadVision's products and services. For
example, because BroadVision's products involve the solicitation of personal
data regarding individual consumers, its business could be limited by laws
regulating the solicitation, collection or processing of this data. The
Telecommunications Act of 1996 prohibits the transmission of some types of
information and content over the Internet. The prohibition's scope and the
liability associated with a Telecommunications Act violation are currently
unsettled. Legislation imposing potential liability upon BroadVision for
information carried on or disseminated through its products would likely cause
the company to implement costly measures to reduce its exposure to this
liability or to discontinue some of its services. BroadVision's business could
be harmed by the expense involved in reacting to actual or potential liability
associated with the Telecommunications Act or other Internet-related laws and
regulations. In addition, the increased attention focused upon liability issues
as a result of the Telecommunications Act could limit the growth of Internet
commerce, which could decrease demand for its products.

    The United States government regulates the export of encryption technology,
which BroadVision's products incorporate. Export regulations, either in their
current form or as may be subsequently enacted, may limit BroadVision's ability
to distribute its software outside the United States. Any revocation or
modification of its export authority or adoption of new laws or regulations
relating to the export of software and encryption technology could limit
BroadVision's international operations. The unlawful export of BroadVision's
software could also harm BroadVision's reputation. Although BroadVision takes
precautions against unlawful export of their software, the global nature of the
Internet makes it difficult to effectively control the distribution of software.

THE IMPOSITION OF SALES AND OTHER TAXES ON PRODUCTS SOLD BY BROADVISION'S
CUSTOMERS OVER THE INTERNET COULD HAVE A NEGATIVE EFFECT ON ONLINE COMMERCE AND,
AS A RESULT, ON DEMAND FOR BROADVISION'S PRODUCTS.

    The imposition of new sales or other taxes could limit the growth of
Internet commerce generally and, as a result, the demand for BroadVision's
products. Recent federal legislation limits the imposition of state and local
taxes on Internet-related sales. In 1998, Congress passed the Internet Tax
Freedom Act, which places a three-year moratorium on state and local taxes on:

    - Internet access, unless the tax was already imposed prior to October 1,
      1998; and

    - discriminatory taxes on electronic commerce.

There is a possibility that Congress may not renew this legislation in 2001. If
Congress chooses not to renew this legislation, state and local governments
would be free to impose taxes on electronically purchased goods.

    BroadVision believes that, in accordance with current industry practice,
most companies that sell products over the Internet do not currently collect
sales or other taxes on shipments of their products

                                       27
<PAGE>
into states or foreign countries where they are not physically present. However,
one or more states or foreign countries may seek to impose sales or other tax
collection obligation on out-of-jurisdiction companies that engage in electronic
commerce. A successful assertion by one or more states or foreign countries that
companies engaged in electronic commerce should collect sales or other taxes on
the sale of their products over the Internet, even though not physically present
in the state or foreign country, could indirectly reduce demand for
BroadVision's products.

BROADVISION'S STOCK PRICE HAS BEEN AND IS LIKELY TO CONTINUE TO BE HIGHLY
VOLATILE.

    The trading price of BroadVision's common stock has been and is likely to
continue to be highly volatile. BroadVision's stock price is subject to wide
fluctuations in response to a variety of factors, including:

    - quarterly variations in operating results;

    - announcements of technological innovations;

    - announcements of new software or services by BroadVision or its
      competitors;

    - changes in financial estimates by securities analysts; or

    - other events or factors that are beyond BroadVision's control.

    In addition, the stock market has experienced significant price and volume
fluctuations that have particularly affected the trading prices of equity
securities of many high technology companies. These fluctuations have often been
unrelated or disproportionate to the operating performance of these companies.
Any negative change in the public's perception of the prospects of Internet or
electronic commerce companies could depress BroadVision's stock price regardless
of BroadVision's results. Other broad market fluctuations may decrease the
trading price of our common stock. In the past, following declines in the market
price of a company's securities, securities class action litigation has often
been instituted against that company. Litigation could result in substantial
costs and a diversion of management's attention and resources.

BROADVISION'S BUSINESS COULD BE HARMED BY YEAR 2000 COMPLIANCE ISSUES.

    The "year 2000 problem" is typically the result of limitations of certain
software written using two digits rather than four digits to define the
applicable year resulting in certain programs recognizing "00" as the year 1900
rather than the year 2000. If software does not correctly recognize date
information in connection with the year change to 2000, BroadVision could
experience system failures or miscalculations that could disrupt operations and
cause, among other things, a temporary inability to process transactions, issue
invoices or engage in similar normal business activities. The most likely
worst-case scenarios could include hardware failure and the failure of
infrastructure services provided by government agencies and other third parties,
such as electricity, telephone service, water transport and Internet services.

    Undetected Year 2000 errors or defects could result in delay or loss of
revenue, diversion of development resources, damage to our reputation and
increased service and warranty costs. Each of BroadVision and Interleaf believes
that the purchasing patterns of customers could potentially be affected by Year
2000 issues as companies expend significant resources to correct or patch their
current software systems for Year 2000 compliance. These expenditures may result
in reduced funds available to purchase software products like those of
BroadVision. Other systems or software used by the BroadVision's customers may
not be Year 2000 compliant. The failure of noncompliant third-party software or
systems could affect the perceived performance of BroadVision's products.

                               Waltham, MA 02451

PURPOSE OF THE SPECIAL MEETING

    The special meeting is being held so that stockholders of Interleaf may
consider and vote upon a proposal to approve the Agreement and Plan of Merger
and Reorganization, dated as of January 26, 2000, by and among BroadVision,
Infiniti Acquisition Sub, Inc., a newly formed and wholly owned subsidiary of
BroadVision, and Interleaf and to transact any other business that properly
comes before the special meeting or any adjournment. Approval of the merger
agreement will constitute approval of the merger and the other transactions
contemplated by the merger agreement.

    If the stockholders of Interleaf approve the merger agreement, Infiniti will
merge with and into Interleaf and Interleaf will survive the merger as a wholly
owned subsidiary of BroadVision. You will receive 1.0395 shares of BroadVision
common stock for each share of Interleaf common stock you hold.

RECOMMENDATION OF INTERLEAF'S BOARD OF DIRECTORS

    AFTER CAREFUL CONSIDERATION, INTERLEAF'S BOARD OF DIRECTORS HAS UNANIMOUSLY
DETERMINED THAT THE MERGER AND THE MERGER AGREEMENT ARE FAIR TO YOU AND IN YOUR
BEST INTERESTS. INTERLEAF'S BOARD HAS APPROVED THE MERGER AGREEMENT AND
UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

RECORD DATE AND VOTING POWERS

    Interleaf's board of directors has fixed the close of business on April   ,
2000 as the record date for determination of Interleaf stockholders entitled to
notice of and entitled to vote at the special meeting. On the record date, there
were       shares of Interleaf common stock outstanding held by approximately
      holders of record. Each holder of Interleaf common stock is entitled to
one vote for each share of Interleaf common stock held on the record date.

VOTING AND REVOCATION OF PROXIES

    The shares represented by the enclosed proxy card, if the proxy card is
executed and returned, will be voted in accordance with your instructions or, if
no choice is specified, the proxy will be voted in favor of approval of the
merger agreement. If any other matters properly come before the special meeting,
the proxy will vote the shares represented by the enclosed proxy card in
accordance with his

                                       31
<PAGE>
best judgment, unless authority to do so is withheld by you in your proxy. You
may revoke your proxy at any time prior to its exercise at the special meeting
by:

    - notifying in writing the Clerk of Interleaf at 62 Fourth Avenue, Waltham,
      Massachusetts 02451;

    - granting a subsequent proxy; or

    - appearing in person and voting at the special meeting.

Attendance at the special meeting will not in and of itself constitute
revocation of a proxy.

REQUIRED VOTE

    A majority of the outstanding shares of Interleaf common stock entitled to
vote at the special meeting, represented in person or by proxy, constitutes a
quorum at the special meeting. The affirmative vote of the holders of at least a
majority of Interleaf's common stock outstanding and entitled to vote at the
special meeting is required to approve the merger agreement.

    As of the record date for the special meeting, Interleaf directors and
executive officers beneficially owned approximately       shares of Interleaf
common stock, which represented approximately      % of all outstanding shares
of Interleaf common stock entitled to vote at the special meeting. All of
Interleaf's directors and executive officers have agreed to vote their shares in
favor of the approval of the merger agreement.

VOTING; PROXIES

    All shares of Interleaf common stock represented by properly executed proxy
cards received before or at the special meeting will, unless the proxy cards are
revoked, be voted in accordance with the instructions indicated on the proxy
cards. If no instructions are indicated on a properly executed proxy card, the
shares will be voted FOR adoption of the merger agreement. You are urged to mark
the box on the proxy card to indicate how to vote your shares.

    If a properly executed proxy card is returned and the stockholder has
abstained from voting on adoption of the merger agreement, the Interleaf common
stock represented by the proxy will be considered present at the special meeting
for the purposes of determining a quorum but will not be considered to have been
voted in favor of the merger agreement. Similarly, if an executed proxy card is
returned by a broker holding shares of Interleaf common stock in street name
that indicates the broker does not have discretionary authority to vote for
approval of the merger agreement, the shares will be considered present at the
meeting for purposes of determining the presence of a quorum but will not be
considered to have been voted in favor of the merger agreement. Your broker will
vote your shares only if you indicate how you want the broker to vote by
following the instructions provided to you by your broker.

    Because approval of the merger agreement requires the affirmative vote of
holders of at least a majority of Interleaf's common stock outstanding as of the
record date, abstentions, failures to vote and broker non-votes all will have
the same effect as votes against approval of the merger agreement.

    Interleaf and BroadVision will equally share the expenses incurred in
connection with the printing and mailing of this proxy statement/prospectus.
Interleaf has retained Corporate Investor Communications, Inc. at an estimated
cost of $5,500 plus reimbursement of expenses to assist in the solicitation of
proxies. Interleaf and Corporate Investor Communications also will request
banks, brokers and other intermediaries holding shares beneficially owned by
others to send this proxy statement/prospectus and related materials to and
obtain voting instructions from the beneficial owners and will reimburse the
holders for their reasonable expenses in so doing.

    YOU SHOULD NOT SEND IN ANY STOCK CERTIFICATES WITH YOUR PROXY CARD.
INSTRUCTIONS FOR THE EXCHANGE OF YOUR SHARES WILL BE MAILED TO YOU AS SOON AS
PRACTICABLE AFTER COMPLETION OF THE MERGER.

                                   THE MERGER

    THIS SECTION OF THE PROXY STATEMENT/PROSPECTUS DESCRIBES MATERIAL ASPECTS OF
THE PROPOSED MERGER AND THE RELATED TRANSACTIONS, BUT IT MAY NOT CONTAIN ALL OF
THE INFORMATION THAT IS IMPORTANT FOR YOU TO KNOW. FOR A MORE COMPLETE
UNDERSTANDING OF THE MERGER, YOU SHOULD CAREFULLY READ THIS ENTIRE PROXY
STATEMENT/ PROSPECTUS AND THE OTHER DOCUMENTS TO WHICH WE REFER.

GENERAL DESCRIPTION OF THE MERGER

    At the effective time, Infiniti Acquisition Sub, Inc., a wholly owned
subsidiary of BroadVision, will be merged with and into Interleaf. Interleaf
will be the surviving corporation and will continue to exist as a wholly owned
subsidiary of BroadVision. In the merger, each share of Interleaf common stock
outstanding at the effective time automatically will be converted into 1.0395
shares of BroadVision common stock.

    Based on the number of shares of Interleaf common stock and BroadVision
common stock outstanding as of the record date,       shares of BroadVision
common stock will be issuable pursuant to the merger agreement, representing
approximately      % of the total BroadVision common stock expected to be
outstanding after such issuance. This assumes that no Interleaf or BroadVision
stock options or warrants are exercised prior to the merger.

BACKGROUND

    During the summer of 1999, Interleaf's senior management became convinced
that Interleaf's e-content products were successfully addressing a new and
rapidly growing market, and that there would be a very short window of
opportunity for Interleaf to secure a strong position in that market. To
capitalize on this opportunity, Interleaf's senior management believed that
Interleaf needed to accelerate its investments in research and development and
sales and marketing initiatives, which would require additional capital.
Accordingly, in August 1999, Interleaf's management proposed, and the company's
board of directors approved, the exploration of two alternative strategies:

    - a registered public offering of shares of Interleaf's common stock to
      raise proceeds of $100.0 million or more; and

    - joint ventures, acquisitions or a merger of Interleaf with another
      company.

THE PROPOSED MANAGEMENT BUY-OUT

    As early as August 1999, Interleaf's management realized that a successful
registered public offering of Interleaf's common stock would require divestiture
of those portions of Interleaf's business unrelated to its e-content business.
This realization was confirmed in December 1999, after consultation with a
number of potential managing underwriters for its proposed public offering of
common stock. Accordingly, Interleaf began to consider various potential
strategies for divesting these portions of its business, known as Interleaf's
e-Publishing division.

    Pursuant to a letter agreement dated December 7, 1999, Interleaf engaged
Stanford Keene to identify prospective purchasers for Interleaf's e-Publishing
division, introduce these prospective purchasers to Interleaf and negotiate with
prospective purchasers through the closing of a transaction. From that date
through the execution of the merger agreement on January 26, 2000, members of
Interleaf's management regularly discussed strategic alternatives for
Interleaf's e-Publishing division with Stanford Keene. With Stanford Keene's
advice, Interleaf decided that the most expedient strategy for a divestiture
would be a management buy-out transaction. In this transaction, as envisioned by
Interleaf, the e-Publishing division's management team, led by Graham Marshall,
Interleaf's Vice President of e-Publishing Solutions, would purchase an 81%
interest in a newly formed company called

                                       33
<PAGE>
e-Publishing Corp., which in turn would hold all of the capital stock of the
three Interleaf subsidiaries that focused on the e-publishing market.

    Interleaf engaged James E. Dawson of Nutter, McClennan & Fish as legal
counsel and Charles C. Hale as a consultant on financial and planning matters
for the e-Publishing management team. Interleaf also engaged David H. Murphree
of Brown, Rudnick, Freed & Gesmer LLP to represent Interleaf in this
transaction. On December 15, 1999, Jaime Ellertson, Interleaf's Chief Executive
Officer, President and Chairman of the Board of Directors, and Peter Rice,
Interleaf's Chief Financial Officer, met with Mr. Marshall to discuss the
specifics of a proposed transaction, including the particular resources that
would be transferred to e-Publishing Corp., and the manner in which the
management team would finance the transaction. On December 23, 1999, Mr. Dawson
proposed initial drafts of a stock purchase agreement and other documents under
which the management buy-out would be consummated. On December 31, 1999, the
respective management representatives reached agreement on preliminary terms of
the management buy-out transaction, subject to review and approval by
Interleaf's board of directors. Until the execution of the merger agreement on
January 26, 2000, various members of Interleaf's management team and its counsel
met with Mr. Marshall and other employees of the e-Publishing division and their
representatives to discuss the possible management buy-out transaction.

    On January 26, 2000, after the merger agreement was executed, Mr. Ellertson
of Interleaf advised Mr. Marshall of Interleaf's e-publishing division of
Interleaf's merger agreement with BroadVision and that, accordingly, the
management buy-out would not take place.

THE PROPOSED PUBLIC OFFERING

    On December 21, 1999, Interleaf held at its offices an organizational
meeting for a proposed public offering. The meeting was attended by: senior
management of Interleaf; Interleaf's outside counsel, Skadden, Arps, Slate,
Meagher & Flom LLP; the four proposed managing underwriters for the public
offering; and counsel to the underwriters. At that meeting, Interleaf
distributed to the attendees a preliminary draft prospectus for the proposed
public offering that had been prepared by its outside counsel. At this
organizational meeting, the proposed lead managing underwriter confirmed that
the registered public offering would likely have a greater chance of success if
Interleaf could divest those portions of its business unrelated to its e-content
market prior to initiating the offering.

    Commencing the week of January 3, 2000 and continuing through January 18,
2000, representatives of Interleaf and the managing underwriters, together with
their respective counsel, participated in business and legal due diligence
reviews related to the proposed public offering. At the same time, a working
group consisting of representatives of Interleaf, Interleaf's outside counsel,
the managing underwriters and underwriters' counsel met between one and two
times each week to work on the draft prospectus for the proposed public
offering. On or about January 18, 2000, Interleaf, in consultation with the
proposed lead managing underwriter for the public offering, postponed further
meetings on the public offering pending resolution of concurrent acquisition
negotiations with BroadVision.

    On January 26, 2000, after the merger agreement was executed, Mr. Rice of
Interleaf advised the proposed lead managing underwriter for Interleaf's
proposed public offering of Interleaf's merger agreement with BroadVision and
that, accordingly, the public offering would not take place.

POSSIBLE STRATEGIC TRANSACTIONS

    On May 14, 1998, Interleaf and Broadview International LLC entered into a
letter agreement that contained the terms of Interleaf's financial advisory
relationship with Broadview, including Broadview's fee structure. On
October 13, 1999, Mr. Ellertson and Mr. Rice of Interleaf met with Scott
Sedlacek, Managing Director of Broadview, Kevin McClelland, Principal of
Broadview, and Jason Auerbach, Vice President of Broadview, to evaluate
Interleaf's strategic alternatives, including potential joint ventures,

                                       34
<PAGE>
acquisitions or a merger of Interleaf with another company. From this date
through the execution of the merger agreement with BroadVision, members of
Interleaf's management regularly discussed Interleaf's strategic alternatives
with Broadview.

    On October 21, 1999, Mr. Sedlacek and Mr. Auerbach of Broadview and
Mr. Ellertson and Mr. Rice of Interleaf held a telephonic meeting to discuss
eleven potential strategic partners for Interleaf, including BroadVision. On
October 22, 1999, Interleaf's board of directors authorized Broadview to
approach eight potential strategic partners, including BroadVision, regarding a
potential strategic transaction with Interleaf. On October 22, 1999, Interleaf's
board of directors also authorized Interleaf's management to continue to prepare
for a registered public offering and a management buy-out of its e-publishing
business.

THE BROADVISION OPPORTUNITY

    On November 5, 1999, representatives of Broadview contacted Perry Thorndyke,
BroadVision's Vice President of Business Development, regarding a potential
combination with an unidentified publicly traded client in the Web-based content
management area. Mr. Thorndyke expressed interest in learning more about the
opportunity at which time Broadview disclosed, on the basis of strict
confidentiality, that its client was Interleaf. At the conclusion of the call,
Broadview sent publicly available background material on Interleaf to
BroadVision.

    On November 15, 1999, Mr. Thorndyke of BroadVision indicated that
BroadVision was interested in meeting with representatives of Interleaf to learn
more about Interleaf and to further discuss a possible business combination.

    On December 9, 1999, Mr. Ellertson and Mr. Rice of Interleaf, Mr. Sedlacek
and Mr. Auerbach of Broadview and Eric Golin, BroadVision's Chief Technology
Officer, Simon King, BroadVision's Vice President of Product Marketing, and
Mr. Thorndyke held a telephonic meeting to discuss Interleaf's business as well
as the merits of a possible acquisition of Interleaf by BroadVision. At the
meeting, Mr. Ellertson and Mr. Rice reviewed Interleaf's operations, technology,
products and marketing strategy with the representatives of BroadVision. On
December 10, 1999, Mr. Thorndyke of BroadVision contacted Broadview to express
its desire to move forward with discussions relating to a possible business
combination.

    On December 20, 1999, representatives of Interleaf, Broadview and
BroadVision held a meeting at BroadVision's headquarters in Redwood City,
California to further discuss the merits of a business combination. Prior to
this meeting, a bilateral confidentiality agreement between Interleaf and
BroadVision was executed. At the meeting, Mr. Ellertson, Mr. Rice and Barry
Briggs, Interleaf's Chief Technology Officer, provided a more detailed overview
of Interleaf's technology, operations and financial condition to members of
BroadVision's management, including Pehong Chen, BroadVision's Chief Executive
Officer, President and Chairman of the Board of Directors, Dr. Golin and
Mr. King. At the conclusion of the meeting, Dr. Chen requested confirmation from
Interleaf of its interest in moving forward with discussions relating to a
possible business combination with BroadVision, which Interleaf agreed to
provide, subject to consultation with Interleaf's board of directors.

    On December 23, 1999, in a telephonic meeting, Mr. Ellertson provided
Interleaf's board of directors with an overview of BroadVision and a summary of
the discussions that had taken place to date and reviewed the potential impact
of continued discussions with BroadVision on Interleaf's proposed public
offering. Mr. Sedlacek and Mr. Auerbach of Broadview presented the board of
directors with an analysis of Interleaf's strategic opportunities, background
information on BroadVision and preliminary valuation information on Interleaf.
Interleaf's board of directors authorized Mr. Ellertson and Mr. Sedlacek to
communicate Interleaf's continued interest in a potential transaction to
BroadVision. In a telephone conversation on December 23, 1999, Mr. Sedlacek of
Broadview communicated Interleaf's continued interest in a potential transaction
to Dr. Chen.

                                       35
<PAGE>
    On December 27, 1999, Dr. Chen expressed to Mr. Sedlacek BroadVision's
interest in continuing to move forward with the potential transaction. Pursuant
to a letter agreement dated January 4, 2000, BroadVision engaged Goldman
Sachs & Co. as its financial advisor for the potential transaction. Thereafter,
through the execution of the agreement, members of BroadVision's management
regularly held internal meetings regarding, and regularly discussed with Goldman
Sachs, a possible business combination with Interleaf. On December 29, 1999,
representatives of Goldman Sachs and Broadview held a telephonic meeting to
discuss the next steps in moving forward with the possible business combination,
including scheduling an initial business and financial due diligence session for
early January 2000. On December 30, 1999, Mr. Ellertson and Mr. Rice of
Interleaf and representatives of Broadview and Goldman Sachs held a telephonic
conference call to provide an overview of Interleaf's market positioning,
technology, operations and financial condition as well as discuss timing
considerations relative to Interleaf's standalone strategy and proposed public
offering.

    On January 3, 2000, BroadVision transmitted an initial business due
diligence request to Interleaf. From January 6, 2000 through January 8, 2000,
several meetings were held at the Westin Waltham Hotel adjacent to Interleaf's
headquarters in Waltham, Massachusetts, involving representatives of Interleaf,
BroadVision, Broadview and Goldman Sachs to review Interleaf's operations,
technology and financial condition, as well as to discuss BroadVision's
operations and the potential synergies of a business combination with Interleaf.
At the meetings, members of Interleaf's management, including Mr. Ellertson,

Counsel, Amanda L. Radice, Interleaf's Vice President of Marketing, Carolyn

    On January 10, 2000 and January 13, 2000, Mr. Ellertson updated Interleaf's
board of directors in telephonic meetings of the board of directors regarding
discussions with BroadVision, and on each such occasion Interleaf's board of
directors authorized Mr. Ellertson to continue the discussions.

    On January 11, 2000, a special meeting of BroadVision's board of directors
was held during which Goldman Sachs made a detailed presentation regarding the

<PAGE>
differences in results and outcomes include those discussed in the sections of
this proxy statement/ prospectus entitled "Summary--Forward-Looking Information"
and "Risk Factors."

BROADVISION'S REASONS FOR THE MERGER

    BroadVision's board of directors believes that the following are reasons
that a business combination with Interleaf would be beneficial to BroadVision
and its stockholders:

    - BroadVision would acquire Interleaf's XML-based content management
      solution, which BroadVision considers to be one of the broadest XML-based
      content solutions available today;

    - the combined company would have the ability to offer complementary product
      lines and to improve BroadVision's existing product offerings;

    - BroadVision would gain access to Interleaf's employees who have specific
      XML-based content management expertise and technical skills;

    - BroadVision and Interleaf would have the ability to combine their
      technological resources to develop a complete Web-based business solution
      and reduce time to market for the combined company's products;

    - BroadVision would gain access to Interleaf's customer base; and

    - the combined company would have the ability to commit greater resources to
      both current and emerging product development efforts and fund the future
      growth of its business.

    The conclusions reached by BroadVision's board of directors with respect to
the factors described above support its determination that the merger and the
issuance of shares of BroadVision common stock in the merger are in the best
interests of BroadVision and its stockholders. In reaching its determination,
BroadVision's board of directors also considered:

    - the judgment, advice and analyses of BroadVision's management with respect
      to the potential strategic, financial and operational benefits of the
      merger, including a favorable recommendation of the merger by
      BroadVision's management based in part on the business, technical,
      financial, accounting and legal due diligence investigations performed
      with respect to Interleaf;

    - the results of operations and financial condition of BroadVision and
      Interleaf and the anticipated accretive effect of the combination on
      BroadVision common stock;

    - the complementary fit between BroadVision's and Interleaf's cultures and
      market segments, which management believes will facilitate integration of
      the two companies; and

    - the terms of the merger agreement and related agreements, including price
      and structure, which were considered by both the board of directors and
      management of BroadVision to provide a fair and equitable basis for the
      merger.

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

    - the possibility that the merger might not be completed in a timely manner
      or at all;

    - the possibility of customer or supplier confusion after the announcement
      of the proposed merger;

    - the substantial accounting charges to be incurred in connection with the
      merger, including costs of integrating the businesses and transaction
      expenses arising from the merger, as well as a significant amount of
      goodwill that would have to be amortized as a result of the merger being
      accounted for as a purchase;

                                       38
<PAGE>
    - the potential negative effect on BroadVision's stock price if revenue and
      earnings expectations of the combined company are not met;

    - the potential loss of Interleaf and BroadVision employees critical to the
      ongoing success of the Interleaf products and to the successful
      integration of the BroadVision and Interleaf product lines;

    - the general difficulties of integrating products, technologies and
      companies;

    - the difficulty of managing separate operations at different geographic
      locations;

    - the possibility of cultural conflicts between the two companies; and

    - the other risks described in the section of this proxy
      statement/prospectus entitled "Risk Factors."

    The foregoing discussion is not exhaustive of all factors considered by
BroadVision's board of directors. Moreover, in view of the variety of factors
considered in connection with its evaluation of the merger and the merger
agreement, BroadVision's board of directors considered the factors as a whole
and did not find it practicable to, and did not, quantify or otherwise assign
relative weight to the specific factors considered in reaching its determination
to approve the merger and the merger agreement. In addition, each member of
BroadVision's board of directors may have considered other factors on an
individual basis, including factors unknown to BroadVision, or given different
weight to different factors considered.

INTERLEAF'S REASONS FOR THE MERGER

    Interleaf's board of directors believes that the following are reasons that
the merger will be beneficial to Interleaf and its stockholders and that
stockholders of Interleaf should vote FOR approval of the merger agreement:

    - the merger would provide Interleaf with access to BroadVision's capital
      and technical resources, which would accelerate Interleaf's research and
      development and sales and marketing efforts, thus shortening Interleaf's
      time to market for its products;

    - Interleaf's stockholders would have the opportunity to participate in the
      growth potential of the combined company after the merger;

    - the combination with BroadVision would enable Interleaf to create more
      long-term value for its customers and employees;

    - the integration of Interleaf's BladeRunner family of products with
      BroadVision's One-To-One product suite would enable Interleaf to offer a
      stronger end-to-end electronic content and electronic commerce solution to
      its customers and significantly shorten the time to market for its
      products;

    - BroadVision's established relationships with large, strategic customers,
      systems integrators and other third parties, larger sales force and
      well-established distribution channels, would increase the number of
      prospective customers and distributors for Interleaf products and
      providers of Interleaf services;

    - the exchange ratio in the merger represents a premium of 39.8% over the
      closing price of Interleaf common stock for the trading day immediately
      prior to announcement of the merger and a premium of 75.4% over the
      average closing price of Interleaf common stock for the 20 trading days
      prior to the announcement of the merger; and

    - Interleaf's financial advisor, Broadview, is of the opinion that, as of
      the date of the merger agreement and subject to the conditions set forth
      in Broadview's opinion addressed to the

                                       39
<PAGE>
      Interleaf board of directors, the exchange ratio is fair, from a financial
      point of view, to Interleaf stockholders.

    In the course of its deliberations, the Interleaf board reviewed with
Interleaf management and outside advisors a number of additional factors
relevant to the merger, including:

    - historical information concerning BroadVision's and Interleaf's respective
      businesses, financial performance and condition, operations, technology,
      management and competitive position, including public reports concerning
      results of operations during the most recent fiscal year and fiscal
      quarter for each company, as filed with the Securities and Exchange
      Commission;

    - Interleaf management's view as to the financial condition, results of
      operations and businesses of BroadVision and Interleaf before and after
      giving effect to the merger based on publicly available earnings estimates
      and business, financial and legal due diligence investigations and
      conducted by Interleaf management and Interleaf's financial and legal
      advisors;

    - current industry and financial market conditions and historical market
      prices, volatility and trading information with respect to BroadVision
      common stock and Interleaf common stock;

    - the consideration to be received by Interleaf stockholders in the merger
      and an analysis of the market value of BroadVision common stock to be
      issued in exchange for each share of Interleaf common stock in light of
      comparable merger transactions;

    - the belief that the terms of the merger agreement and the stock option
      agreement, including the parties' representations, warranties, covenants
      and the conditions to the parties' respective obligations, are reasonable;

    - Interleaf management's view as to the prospects of Interleaf as an
      independent company, including its prospects for a successful public
      offering and concurrent management buy-out;

    - Interleaf management's view as to the potential for other third parties to
      enter into strategic relationships with or to acquire Interleaf;

    - detailed financial analysis and pro forma and other information with
      respect to the companies presented to Interleaf's board of directors by
      Broadview, including Broadview's opinion that the exchange ratio set forth
      in the merger agreement is fair, from a financial point of view, to
      Interleaf's stockholders;

    - the impact of the merger on Interleaf's customers and employees; and

    - reports from Interleaf's management, legal advisors and financial advisors
      as to the results of their due diligence investigation of BroadVision.

    Interleaf's board of directors also specifically considered the terms of the
merger agreement regarding Interleaf's right to consider and negotiate other
strategic transaction proposals and termination fees as well as the stock option
agreement. In addition, Interleaf's board of directors noted that the merger is
expected to be a tax-free reorganization under Section 368(a) of the Internal
Revenue Code of 1986, as amended, and accounted for as a purchase transaction in
which a significant amount of goodwill is expected to be created on the books of
the combined company as a result of the transaction. Interleaf's board of
directors considered various alternatives to the merger for enhancing long-term
stockholder value, including the possibility of other potential strategic
transactions, such as completing the proposed management buy-out transaction and
public offering described in the section of this proxy statement/prospectus
entitled "The Merger--Background," or otherwise remaining as an independent
company.

                                       40
<PAGE>
    Interleaf's board of directors also identified and considered a variety of
potentially negative factors in its deliberations concerning the merger,
including:

    - the risk that the operations of Interleaf and BroadVision might not be
      successfully integrated, including the risk that the two companies'
      products are not technically compatible;

    - the risk that the potential benefits sought in the merger might not be
      fully realized;

    - recognizing that BroadVision common stock has traded at high multiples,
      the risk that these multiples might not be sustained in the future;

    - the possibility that the merger might not be completed, and the effect of
      the public announcement of the merger on:

       - Interleaf's sales and operating results,

       - Interleaf's ability to attract and retain key management, marketing and
         technical personnel;

       - the progress of ongoing Interleaf development projects;

    - the possibility of customer or supplier confusion after the announcement
      of the proposed merger;

    - the substantial accounting charges to be incurred in connection with the
      merger, including costs of integrating the businesses and transaction
      expenses arising from the merger, as well as the significant amount of
      goodwill that would have to be amortized as a result of the merger being
      accounted for as a purchase;

    - the possibility that the option provided for in the stock option
      agreement, if exercised, would result in significant dilution to existing
      Interleaf stockholders;

    - the potential loss of Interleaf and BroadVision employees critical to the
      ongoing success of the Interleaf products and to the successful
      integration of the BroadVision and Interleaf product lines;

    - the fact that the exchange ratio is fixed at 1.0395;

    - the difficulty of managing separate operations at different geographic
      locations; and

    - the other risks described in the section of this proxy
      statement/prospectus entitled "Risk Factors."

    Interleaf's board of directors believed that these factors, together with
its review of the merger agreement, supported its recommendation of the merger.

    The foregoing discussion is not exhaustive of all factors considered by
Interleaf's board of directors. Moreover, in view of the variety of factors
considered in connection with its evaluation of the merger and the merger
agreement, Interleaf's board of directors considered the factors as a whole and
did not find it practicable to, and did not, quantify or otherwise assign
relative weight to the specific factors considered in reaching its determination
to approve the merger and the merger agreement. In addition, each member of
Interleaf's board may have considered other factors on an individual basis,
including factors unknown to Interleaf, or given different weight to different
factors considered.

RECOMMENDATION OF INTERLEAF'S BOARD OF DIRECTORS

    AFTER CAREFUL CONSIDERATION, INTERLEAF'S BOARD OF DIRECTORS BELIEVES THAT
THE MERGER AND THE MERGER AGREEMENT ARE FAIR TO YOU AND IN YOUR BEST INTERESTS.
INTERLEAF'S BOARD OF DIRECTORS HAS APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY
RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

                                       41

    In considering the recommendation of Interleaf's board of directors with
respect to the merger and the merger agreement, you should be aware that certain
directors and officers of Interleaf have certain interests in the merger that
may be different from, or are in addition to, yours. For a more complete
discussion of the interests of certain officers and directors, we refer you to
the section of this proxy statement/prospectus entitled "Interests of Officers
and Directors in the Merger."

OPINION OF INTERLEAF'S FINANCIAL ADVISOR

    Pursuant to a letter agreement dated as of May 14, 1998, Broadview
International LLC was engaged to act as financial advisor to Interleaf's board
of directors. Interleaf's board of directors regarding the fairness of the
exchange ratio, from a financial point of view, to Interleaf stockholders.
Interleaf's board of directors selected Broadview to act as financial advisor
based on Broadview's reputation and experience in the information technology,
communication and media sector and the e-business software industry in
particular. At the January 26, 2000 Interleaf board meeting, Broadview rendered
its opinion that, as of that date, based upon and subject to the various factors
and assumptions, the exchange ratio was fair, from a financial point of view, to
Interleaf stockholders.

    BROADVIEW'S LETTER OPINION IS ATTACHED AS ANNEX D TO THIS PROXY
STATEMENT/PROSPECTUS. INTERLEAF STOCKHOLDERS ARE URGED TO, AND SHOULD, READ THE
BROADVIEW LETTER OPINION CAREFULLY AND IN ITS ENTIRETY. THE BROADVIEW LETTER
OPINION IS DIRECTED TO INTERLEAF'S BOARD OF DIRECTORS AND ADDRESSES ONLY THE
FAIRNESS OF THE EXCHANGE RATIO TO INTERLEAF STOCKHOLDERS FROM A FINANCIAL POINT
OF VIEW AS OF THE DATE OF THE OPINION. THE BROADVIEW LETTER OPINION DOES NOT
ADDRESS ANY OTHER ASPECT OF THE MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION
TO ANY INTERLEAF STOCKHOLDER AS TO HOW TO VOTE AT THE SPECIAL MEETING. THE
SUMMARY OF THE BROADVIEW LETTER OPINION SET FORTH IN THIS PROXY
STATEMENT/PROSPECTUS, ALTHOUGH MATERIALLY COMPLETE, IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.

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

    - reviewed the terms of the draft merger agreement furnished to Broadview by
      Skadden, Arps on January 26, 2000;

    - reviewed certain publicly available financial statements and other
      information of Interleaf and BroadVision;

    - reviewed Interleaf's draft registration statement on Form S-3 which had
      been prepared in connection with a potential registered public offering of
      Interleaf common stock;

    - reviewed certain internal financial and operating information (including
      certain preliminary financial results and projections) for Interleaf
      prepared for and provided to Broadview by Interleaf management;

    - participated in discussions with Interleaf and BroadVision management
      concerning the operations, business strategy, financial performance and
      prospects for Interleaf and BroadVision;

    - discussed the strategic rationale for the merger with Interleaf and
      BroadVision management;

    - reviewed the reported closing prices and trading activity for Interleaf
      common stock and BroadVision common stock;

    - compared certain aspects of the financial performance of Interleaf and
      BroadVision with other comparable public companies;

    - analyzed available information, both public and private, concerning other
      comparable mergers and acquisitions;

    - reviewed recent equity research analyst reports covering Interleaf and
      BroadVision;

                                       42
<PAGE>
    - analyzed the anticipated effect of the merger on the future financial
      performance of BroadVision;

    - participated in negotiations and discussions related to the merger with
      representatives of Interleaf, Interleaf's legal advisors, representatives
      of BroadVision and BroadVision's financial and legal advisors; and

    - conducted other financial studies, analyses and investigations as
      Broadview deemed appropriate for purposes of its opinion.

    In rendering its opinion, Broadview relied, without independent
verification, on the accuracy and completeness of all the financial and other
information, including without limitation the representations and warranties
contained in the merger agreement, that was publicly available or furnished to
Broadview by Interleaf or BroadVision. With respect to the financial projections
examined by Broadview, Broadview assumed that they were reasonably prepared and
reflected the best available estimates and good faith judgment of Interleaf's
management as to the future performance of Interleaf. Broadview also assumed
that neither Interleaf nor BroadVision was currently involved in any material
transaction as of the date of Broadview's opinion other than the merger of
Interleaf and BroadVision, other publicly announced transactions and those
activities undertaken in the ordinary course of conducting their respective
businesses.

    Broadview did not make or obtain any independent appraisal or valuation of
any of Interleaf's assets. Broadview's opinion is necessarily based upon market,
economic, financial and other conditions as they existed and could be evaluated
as of January 26, 2000, and any change in those conditions after that date would
require a reevaluation of Broadview's opinion. The Broadview opinion did not
express any opinion as to the price at which BroadVision common stock will trade
at any time.

    The following is a brief summary of the sources of information and valuation
methodologies employed by Broadview in rendering Broadview's opinion. These
analyses were presented to the Interleaf board at its meeting on January 26,
2000. This summary includes the financial analyses used and deemed to be
material by Broadview, but does not purport to be a complete description of
analyses performed by Broadview in arriving at its opinion. This summary of
financial analyses includes information presented in tabular format. In order to
fully understand the financial analyses used by Broadview, the tables must be
read together with the text of each summary. The tables alone do not constitute
a complete description of the financial analyses.

INTERLEAF STOCK PERFORMANCE ANALYSIS

    Broadview compared the recent stock performance of Interleaf with that of
the S&P 500 and with the performance of an index of eight public companies that
Broadview deemed comparable to Interleaf's e-content business, referred to as
the Comparable E-Content Company Index. Broadview selected companies competing
in the Web content management and Web tools software industry with revenues
between $5 million and $75 million and revenue growth greater than 35% for the
last reported twelve months. The Comparable E-Content Company Index includes the
following companies, referred to as the Comparable E-Content Companies: Allaire
Corporation; BackWeb Technologies Ltd.; Bluestone Software, Inc.;
Interwoven, Inc.; IntraNet Solutions, Inc.; SilverStream Software, Inc.;
Viador Inc. and Vignette Corporation.

PUBLIC COMPANY COMPARABLE ANALYSIS

    Broadview considered ratios of share price and market capitalization,
adjusted for cash and debt when necessary, to selected historical and projected
operating results in order to derive multiples placed on a company in a
particular market segment. In order to perform this analysis, Broadview compared
financial information of Interleaf's e-content business with publicly available
information for the Comparable E-Content Companies. While earnings-based
multiples are metrics often used to value public companies, they were not used
in this analysis since neither Interleaf's e-content business nor the majority
of the Comparable E-Content Companies are profitable. For this analysis, as well
as other analyses, Broadview examined publicly available information, as well as
a range of estimates based on securities research analyst reports and financial
projections prepared by Interleaf management.

    Broadview also compared financial information of Interleaf's e-publishing
business with four public companies that Broadview deemed comparable to
Interleaf's e-publishing business, referred to as the Comparable E-Publishing
Companies. Broadview selected companies competing in the document outsourcing
services market with revenues between $5 million and $75 million for the last
reported twelve months. The Comparable E-Publishing Companies include the
following companies: Docucon, Inc.; ImageMax, Inc.; Innodata Corporation and
Saztec International, Inc.

    In analyzing the e-content business, forward multiples for the Comparable
E-Content Companies were derived from projections in equity analyst reports.
These multiples were then applied to Interleaf's internal management
projections, which assumed that Interleaf would raise an additional
$100 million in a registered public offering of common stock in the first half
of calendar year 2000.

    The following table presents, as of January 25, 2000, the median and range
of multiples for the Comparable E-Content Companies of total market
capitalization (defined as equity market capitalization plus total debt, minus
cash and cash equivalents) divided by selected operating metrics:

    No company utilized in the public company comparables analysis as a
comparison is identical to Interleaf. In evaluating the comparables, Broadview
made numerous assumptions with respect to Web content management, Web tools
software and e-publishing industry performance and general economic conditions,
many of which are beyond the control of Interleaf. Mathematical analysis, such
as determining the median, average, or range, is not in itself a meaningful
method of using comparable company data.

TRANSACTION COMPARABLES ANALYSIS

    Broadview considered ratios of equity purchase price, adjusted for the
seller's cash and debt when appropriate, to selected historical operating
results in order to indicate multiples that strategic and financial acquirers
have been willing to pay for companies in a particular market segment. In order
to perform this analysis, Broadview reviewed a number of transactions Broadview
considered similar to Interleaf's e-content business, referred to as E-Content
Transaction Comparables. Broadview selected these transactions by choosing
recent transactions involving sellers in the Web-based customer relationship
management, or CRM, software industry and Web-based tools software industry with
revenues between $2 million and $30 million in the last reported twelve months
before the acquisition. For this analysis, as well as other analyses, Broadview
examined publicly available information, as well as information from Broadview's
proprietary database of published and confidential merger and acquisition
transactions in the information technology, communication and media industries.
These transactions consisted of three confidential transactions and the

of businesses that Broadview considered similar to Interleaf's e-publishing
business, referred to as the E-Publishing Transaction Comparables. Broadview
selected these transactions by choosing recent transactions involving sellers in
the document outsourcing services industry with revenues less than $50 million
in the last reported twelve months before the acquisition. These transactions
consisted of two confidential transactions and the acquisition of:

    No transaction utilized as a comparable in the transaction comparables
analysis is identical to the merger of Interleaf and BroadVision. In evaluating
the comparables, Broadview made numerous assumptions with respect to the
Web-based CRM software industry and Web-based tools software industry's
performance and general economic conditions, many of which are beyond the
control of Interleaf or BroadVision. Mathematical analysis, such as determining
the average, median or range, is not in itself a meaningful method of using
comparable transaction data.

TRANSACTION PREMIUMS ANALYSIS

    Broadview considered the premiums paid above a seller's share price in order
to determine the additional value strategic and financial acquirers, when
compared to public stockholders, are willing to pay for companies in a
particular market segment. In order to perform this analysis, Broadview reviewed
a number of transactions, selected from its proprietary database, involving
publicly held software companies with an equity purchase price between
$100.0 million and $1.0 billion. These transactions consisted of the acquisition
of:

PRESENT VALUE OF PROJECTED SHARE PRICE ANALYSIS

    Broadview calculated the present value of potential future share prices of
Interleaf common stock on a standalone basis using Interleaf management's
projections for the twelve months ending December 31, 2000. The implied share
price was calculated using the median total market capitalization to last twelve
months revenue multiple for the Comparable E-Content Companies and a discount
rate determined by an industry standard capital asset pricing model with the
risk implied by the past stock performance of the Comparable E-Content
Companies. Broadview assumed that the median multiple would remain constant
going forward and that Interleaf would raise $100.0 million in a registered
public offering of common stock in the first half of calendar year 2000. The
implied share value adjusted for the median implied value from the e-publishing
public company comparables and transaction comparables was $220.69.

EXCHANGE RATIO ANALYSIS

    Broadview compared the ratios of the closing prices of Interleaf common
stock divided by the corresponding prices of BroadVision common stock over the
period from January 26, 1999 through January 25, 2000 with the exchange ratio
contained in the merger agreement, referred to as the historical exchange ratio,
which was not adjusted to reflect BroadVision's three-for-one stock split
effective on February 21, 2000. The historical exchange ratio has ranged from
0.1288 to 0.5155, with an average of 0.2870.

RELATIVE CONTRIBUTION ANALYSIS

    Broadview examined the relative contribution of Interleaf to BroadVision for
a number of historical and projected operating metrics. In this analysis,
projected figures for Interleaf are based on management estimates for the
e-content business and projected figures for BroadVision are derived from
analyst estimates.

    The following reflect the relative contribution of Interleaf and BroadVision
for each operating metric:

RELATIVE OWNERSHIP ANALYSIS

    A relative ownership analysis measures each of the merging companies'
relative equity ownership and relative entity ownership. Entity ownership
compares the relative entity values of the combining companies; entity value
equals equity value plus total debt, plus the median implied value from the
e-publishing public company comparables and transaction comparables, minus cash
and cash equivalents. At the exchange ratio, the implied equity ownership is
6.0% for Interleaf and 94.0% for BroadVision, while the implied entity ownership
is 5.9% for Interleaf and 94.1% for BroadVision.

BROADVISION STOCK PERFORMANCE ANALYSIS

    Broadview compared the recent stock performance of BroadVision with that of
the S&P 500 and with an index of five public companies that Broadview deemed
comparable to BroadVision, referred to as the BroadVision Comparable Company
Index. Broadview selected companies competing in the Web-based CRM e-commerce
application software industry, with revenue between $20.0 million and
$100.0 million for the last reported twelve months. The BroadVision Comparable
Company Index consists of the following companies: Vignette Corporation; Art
Technology Group, Inc.; InterWorld Corporation; Calico Commerce, Inc. and Open
Market, Inc.

EVALUATION OF BROADVISION PUBLIC COMPANY COMPARABLES

    Broadview compared financial information of BroadVision with publicly
available information for the BroadVision Comparable Companies. For this
analysis, as well as other analyses, Broadview examined publicly available
information, as well as a range of estimates based on securities research
analyst reports.

PRO FORMA COMBINATION ANALYSIS

    Broadview calculated the pro forma impact of the merger on the combined
entity's projected earnings per share for the calendar years 2000 and 2001
taking into consideration various financial effects that will result from
consummation of the merger. This analysis relied upon certain financial and
operating assumptions derived from equity research analysts and publicly
available data about BroadVision, certain internal financial projections
provided by Interleaf management about Interleaf and synergy assumptions
determined through discussions with Interleaf management, BroadVision management
and BroadVision's financial advisors. Broadview assumed that the merger would be
treated as a purchase transaction and that the combination would result in
revenue enhancements of $7.5 million and $3.6 million in cost savings to the
combined entity in calendar year 2000, and revenue enhancements of
$20.4 million and $7.2 million in cost savings to the combined entity in
calendar year 2001. Based on this analysis, the pro forma purchase model
indicates earnings per share dilution of $0.91, excluding any purchased research
and development write-off, for the fiscal year ending December 31, 2000, $0.34
dilution for the three months ending September 30, 2000, $0.31 dilution for the
three months ending December 31, 2000 and $1.07 dilution for the fiscal year
ending December 31, 2001. Excluding the amortization of goodwill, the pro forma
purchase model indicates earnings per share accretion of $0.02, excluding
purchased research and development write-off, for the fiscal year ending
December 31, 2000, $0.00 dilution for the three months ending September 30,
2000, $0.03 accretion for the three months ending December 31, 2000 and $0.28
accretion for the fiscal year ending December 31, 2001. Broadview also examined
the effects of varying amounts of potential cost savings and revenue
enhancements and the incremental accretion or dilution related to those synergy
assumptions.

CONSIDERATION OF THE DISCOUNTED CASH FLOW METHODOLOGY

    While discounted cash flow is a commonly used valuation methodology,
Broadview did not employ such an analysis for the purposes of this opinion.
Discounted cash flow analysis is most appropriate for companies that exhibit
relatively steady or somewhat predictable streams of future cash flow. For a
company with high projected revenue growth, such as Interleaf, a preponderance
of the value in a valuation based on discounted cash flow will be in the
terminal value of the entity, which is extremely sensitive to assumptions about
the sustainable long-term growth rate of the company. Given the uncertainty in
estimating both the future cash flows and a sustainable long-term growth rate
for Interleaf, Broadview considered a discounted cash flow analysis
inappropriate for valuing Interleaf.

                                       50
<PAGE>
    In connection with the review of the merger by the Interleaf board of
directors, Broadview performed a variety of financial and comparative analyses.
The summary set forth above does not purport to be a complete description of the
analyses performed by Broadview in connection with the merger.

    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Broadview considered the results of all of its analyses as a
whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, Broadview believes that selecting any portion of
its analyses, without considering all analyses, would create an incomplete view
of the process underlying its opinion.

    In performing its analyses, Broadview made numerous assumptions with respect
to industry performance and general business and economic conditions and other
matters, many of which are beyond the control of Interleaf or BroadVision. The
analyses performed by Broadview are not necessarily indicative of actual values
or actual future results, which may be significantly more or less favorable than
suggested by such analyses. The exchange ratio under the merger agreement and
other terms of the merger agreement were determined through arm's length
negotiations between Interleaf and BroadVision and were approved by the
Interleaf board of directors. Broadview provided advice to the Interleaf board
of directors during such negotiations; however, Broadview did not recommend any
specific consideration to the Interleaf board of directors or that any specific
consideration constituted the only appropriate consideration for the merger. In
addition, Broadview's opinion and presentation to the Interleaf board of
directors was one of many factors taken into consideration by the Interleaf
board of directors in making its decision to approve the merger. Consequently,
the Broadview analyses as described above should not be viewed as determinative
of the opinion of the Interleaf board of directors with respect to the value of
Interleaf or of whether the Interleaf board of directors would have been willing
to agree to a different consideration.

    Upon consummation of the merger, Interleaf would be obligated to pay
Broadview a transaction fee of approximately $7.5 million. Interleaf has already
paid Broadview a fairness opinion fee of $1.25 million, which will be credited
against the transaction fee payable by Interleaf upon completion of the merger.
In addition, Interleaf has agreed to reimburse Broadview for its reasonable
expenses, including fees and expenses of its counsel, and to indemnify Broadview
and its affiliates against certain liabilities and expenses related to their
engagement, including liabilities under the federal securities laws. The terms
of the fee arrangement with Broadview, which Interleaf and Broadview believe are
customary in transactions of this nature, were negotiated at arm's length
between Interleaf and Broadview, and the Interleaf board of directors was aware
of the nature of the fee arrangement, including the fact that a significant
portion of the fees payable to Broadview is contingent upon completion of the
merger.

INTERESTS OF INTERLEAF'S OFFICERS AND DIRECTORS IN THE MERGER

    When considering the recommendation of Interleaf's board of directors to
approve the merger agreement, you should be aware that certain Interleaf
directors and officers have interests in the merger that are different from, or
are in addition to, yours.

STOCK OPTIONS

    All directors and executive officers of Interleaf hold options to purchase
Interleaf common stock. Under the merger agreement, all stock options of
Interleaf outstanding immediately prior to the merger, including those held by
directors and officers of Interleaf, will be assumed by BroadVision and will be
deemed to constitute options to acquire shares of BroadVision common stock with
appropriate adjustments in share amounts and exercise prices to reflect the
exchange ratio in the merger. You should read the section of this proxy
statement/prospectus entitled "Certain Terms of the Merger

                                       51
<PAGE>
Agreement-Interleaf Stock Options" for a more complete description of the
treatment of outstanding stock options in the merger. Under the terms of
Interleaf's option agreements with officers, the vesting of all options granted
prior to June 1999 accelerates and the options become fully exercisable upon a
change in control of Interleaf, which includes the stockholder vote approving
the merger. Options granted to officers from and after June 1999 become fully
vested and exercisable only if the officer is terminated without cause or if he
or she resigns for good reason, as those terms are defined in the option
agreement, within 12 months following a change in control of Interleaf, which
includes the stockholder vote approving the merger.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

    BroadVision has agreed to indemnify the officers and directors of Interleaf
for their acts and omissions as officers and directors of Interleaf prior to the
merger to the maximum extent permitted by Massachusetts law for a period of six
years and to provide and maintain insurance coverage for these purposes for a
period of at least three years after the consummation of the merger.

CHANGE OF CONTROL SEVERANCE PLAN

    Prior to signing the merger agreement, Interleaf had in place a change in
control severance plan that provides a cash severance benefit to all executive
officers. The plan provides for a severance payment equal to 12 months' salary
plus bonus to be made to each executive officer who is terminated by Interleaf
without cause or resigns for good reason, as those terms are defined in the
severance plan, within 12 months following a change in control of Interleaf,
which includes the stockholder vote approving the merger.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

    The following is a summary of certain U.S. federal income tax consequences
of the merger generally applicable to the holders of Interleaf common stock that
exchange their Interleaf common stock for BroadVision common stock in the
merger. This summary addresses only those stockholders who hold their Interleaf
common stock as a capital asset and will hold BroadVision common stock received
in exchange therefor as a capital asset. This discussion does not address all
U.S. federal income tax considerations that may be relevant to particular
stockholders in light of their individual circumstances or to stockholders that
are subject to special rules, such as financial institutions, tax-exempt
organizations, insurance companies, dealers in securities, foreign stockholders,
to stockholders who hold Interleaf common stock as part of a straddle, hedge, or
conversion transaction, to stockholders who acquired their Interleaf common
stock pursuant to the exercise of employee stock options or otherwise as
compensation, to stockholders whose shares are qualified small business stock
for purposes of Section 1202 of the Internal Revenue Code of 1986, as amended,
referred to as the Code, and persons who hold, directly or indirectly, 10% or
more of Interleaf common stock. The following summary is based upon the
provisions of the Code, applicable Treasury Regulations thereunder, judicial
decisions and current administrative rulings, as of the date hereof, all of
which are subject to change, possibly on a retroactive basis. Tax consequences
under state, local, foreign and other laws are not addressed in this discussion.
Furthermore, the following discussion does not address the tax implications of a
failure of the merger to qualify as a reorganization within the meaning of
Section 368(a) of the Code. Each stockholder is advised to consult his or her
tax advisor as to the particular facts and circumstances which may be unique to
that stockholder and also as to any estate, gift, state, local or foreign tax
considerations arising out of this merger.

    No rulings have been or will be requested from the Internal Revenue Service
with respect to any of the matters addressed in this discussion. There can be no
assurance that future legislation, regulations, administrative rulings or court
decisions would not alter the tax consequences set forth below. It is a
condition to the obligation of BroadVision to consummate the merger that
BroadVision

                                       52
<PAGE>
receive an opinion from its counsel, Cooley Godward LLP, and it is a condition
to the obligation of Interleaf to consummate the merger that Interleaf receive
an opinion from its counsel, Skadden, Arps, Slate, Meagher & Flom LLP, in each
case substantially to the effect that, based upon certain facts,
representations, and assumptions, the merger will be treated as a reorganization
within the meaning of section 368(a) of the Code. In the event that counsel for
either BroadVision or Interleaf fails to provide the opinion, the conditions
will nonetheless be deemed satisfied if counsel to the other company provides
the opinion. The issuance of these opinions is conditioned, among other things,
on the receipt by Cooley Godward and Skadden, Arps, Slate, Meagher & Flom of
representation letters, which will be reconfirmed prior to the closing of the
merger, from each of BroadVision and Interleaf, in each case, in form and
substance reasonably satisfactory to Cooley Godward and Skadden, Arps, Slate,
Meagher & Flom. The following summary assumes that the merger will be
consummated as described in the merger agreement and this proxy
statement/prospectus and that the merger will be treated as a reorganization
within the meaning of section 368(a) of the Code.

    TREATMENT OF INTERLEAF, BROADVISION AND INFINITI ACQUISITION SUB.  No gain
or loss will be recognized by Interleaf, BroadVision or Infiniti Acquisition Sub
as a result of the merger.

    EXCHANGE OF INTERLEAF COMMON STOCK FOR BROADVISION COMMON STOCK.  A holder
of Interleaf common stock whose shares of Interleaf common stock are exchanged
in the merger for BroadVision common stock will not recognize gain or loss,
except to the extent of cash, if any, received in lieu of fractional shares. See
the section below entitled "Cash in Lieu of Fractional Shares." The aggregate
tax basis of BroadVision common stock received by the holder will be equal to
the aggregate tax basis of the Interleaf common stock exchanged therefor,
excluding any portion of the holder's basis allocated to fractional shares, and
the holding period of BroadVision common stock received will include the holding
period of the Interleaf common stock exchanged therefor.

    CASH IN LIEU OF FRACTIONAL SHARES.  A holder of Interleaf common stock who
receives cash in lieu of fractional shares of BroadVision common stock will be
treated as having received the fractional shares pursuant to the merger and then
as having exchanged the fractional shares for cash in a redemption by
BroadVision. The amount of any gain or loss will be equal to the difference
between the ratable portion of the tax basis of the Interleaf common stock
exchanged in the merger that is allocated to the fractional shares and the cash
received in lieu thereof. Any gain or loss will constitute long-term capital
gain or loss if the Interleaf common stock has been held by the holder for more
than one year at the time of the consummation of the merger.

    REPORTING REQUIREMENTS.  Each holder of Interleaf common stock that receives
BroadVision common stock in the merger will be required to retain records and
file with the stockholder's federal income tax return a statement setting forth
certain facts relating to the merger.

    DISSENTING HOLDERS OF INTERLEAF COMMON STOCK.  A holder of Interleaf common
stock that receives solely cash in exchange for the holder's stock pursuant to
the exercise of dissenters' rights under Massachusetts Business Corporation Law
will recognize gain or loss equal to the difference between the adjusted tax
basis of the Interleaf common stock surrendered and the amount of cash received
therefor. The gain or loss will constitute long-term capital gain or loss if the
Interleaf common stock has been held by the holder for more than one year at the
time of the consummation of the merger.

    With respect to a cash payment received by an Interleaf stockholder in lieu
of a fractional share of BroadVision common stock, a noncorporate stockholder of
Interleaf may be subject to backup withholding at a rate of 31%. However, backup
withholding will not apply to a stockholder who either (i) furnishes a correct
taxpayer identification number and certifies that he or she is not subject to
backup withholding by completing the substitute Form W-9 that will be included
as part of the transmittal letter, or (ii) otherwise proves to BroadVision and
its exchange agent that the stockholder is exempt from backup withholding.

ANTICIPATED ACCOUNTING TREATMENT

    The merger will be accounted for using the purchase method of accounting
under which the total consideration paid in the merger will be allocated to the
tangible and identifiable intangible assets acquired and liabilities assumed of
Interleaf on the basis of their estimated fair values on the acquisition date.
The excess of purchase price over tangible and identifiable intangible assets
acquired and liabilities assumed will be recorded as goodwill.

GOVERNMENTAL APPROVALS

    Transactions such as the merger are subject to review by the Department of
Justice and the Federal Trade Commission to determine whether they comply with
applicable antitrust laws. Under the provisions of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, the merger may not be
consummated until the specified waiting period requirements of that Act have
been satisfied. BroadVision and Interleaf filed notification reports, together
with requests for early termination for the waiting period, with the Department
of Justice and the Federal Trade Commission under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, on February 11, 2000. Interleaf
and BroadVision received notice of early termination of the waiting period on
February 24, 2000.

RESTRICTIONS ON RESALES

    The shares of BroadVision common stock to be received by Interleaf
stockholders in the merger have been registered under the Securities Act of
1933, as amended, and, except as described in this paragraph, may be freely
traded without restriction. The shares of BroadVision common stock to be issued
in the merger and received by persons who may be considered to be affiliates of
Interleaf within the meaning of Rule 144 under the Securities Act before the
merger may be resold by them only 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.

BroadVision's registration statement on Form S-4, of which this proxy
statement/prospectus forms a part, does not cover the resale of shares of
BroadVision common stock to be received by Interleaf affiliates in the merger.

                     CERTAIN TERMS OF THE MERGER AGREEMENT

    THE FOLLOWING SUMMARY DESCRIBES THE MATERIAL TERMS OF THE AGREEMENT AND PLAN
OF MERGER AND REORGANIZATION, DATED AS OF JANUARY 26, 2000, AMONG BROADVISION,
INFINITI ACQUISITION SUB, INC., A WHOLLY OWNED SUBSIDIARY OF BROADVISION, AND
INTERLEAF. THE FULL TEXT OF THE MERGER AGREEMENT IS ATTACHED AS ANNEX A TO THIS
PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. WE ENCOURAGE
YOU TO READ THE ENTIRE MERGER AGREEMENT.

THE MERGER

    The merger agreement provides that at the effective time, Infinity
Acquisition Sub will be merged with and into Interleaf. Upon completion of the
merger, Interleaf will continue as the surviving corporation and will be a
wholly owned subsidiary of BroadVision.

EFFECTIVE TIME OF THE MERGER

    The merger will become effective when articles of merger are filed with the
Secretary of the Commonwealth of the Commonwealth of Massachusetts. If all of
the conditions to the merger contained in the merger agreement are satisfied or
waived, we anticipate that the effective time will occur on the date of the
special meeting or as soon as practicable following the special meeting.

MANNER AND BASIS OF CONVERTING SHARES

    At the effective time, each share of Interleaf common stock will
automatically be converted into 1.0395 shares of BroadVision common stock. This
multiple is referred to in this proxy statement/ prospectus as the exchange
ratio.

    As soon as reasonably practicable following the effective time, American
Securities Transfer & Trust, Inc., which has been selected by BroadVision to act
as exchange agent, will mail a transmittal letter to each record holder of
Interleaf common stock to exchange their Interleaf common stock certificates for
BroadVision common stock certificates and cash for any fractional share.
Transmittal letters also will be available following completion of the merger at
the offices of the exchange agent, American Securities Transfer & Trust, Inc.,
c/o Kathy Hagerty, 12039 W. Alameda Parkway, Lakewood, Colorado 80228.
Additionally, holders of Interleaf common stock may, at their option, after the
effective time, physically surrender in person at the offices of the exchange
agent their Interleaf stock certificates for BroadVision common stock
certificates. Interleaf stockholders should not exchange their stock
certificates before the effective time. After the effective time, transfers of
Interleaf common stock will not be registered on the stock transfer books of
Interleaf.

    No fractional shares of BroadVision common stock will be issued in the
merger. Instead of any fractional share, you will receive a cash amount, rounded
to the nearest whole cent, without interest, based on the closing price for
BroadVision common stock reported by Nasdaq on the date the merger becomes
effective.

    After the effective time, and until it is surrendered and exchanged, each
certificate that previously evidenced Interleaf common stock will be deemed to
evidence shares of BroadVision common stock and the right to receive cash
instead of any fractional share. BroadVision will not pay dividends or other
distributions on any shares of BroadVision common stock to be issued in exchange
for any unsurrendered Interleaf common stock certificate until the Interleaf
common stock certificate is surrendered as provided in the merger agreement.

INTERLEAF STOCK OPTIONS

    At the effective time, BroadVision will assume each outstanding Interleaf
stock option, and each outstanding Interleaf stock option will become an option
to purchase that number of shares of

                                       55
<PAGE>
BroadVision common stock equal to the number of shares of Interleaf common stock
subject to that Interleaf stock option immediately before the effective time,
multiplied by the exchange ratio and rounded down to the nearest whole share.
The exercise price per share of BroadVision common stock subject to each assumed
stock option will be equal to the exercise price per share of the Interleaf
common stock subject to the corresponding Interleaf stock option divided by the
exchange ratio and rounded up to the nearest cent. All other terms and
conditions of the Interleaf stock options will not change.

    Based on the Interleaf stock options outstanding at the record date, and
assuming no Interleaf stock options are exercised prior to the effective time,
BroadVision will be required at the effective time to reserve       shares of
BroadVision common stock for issuance upon exercise of the Interleaf stock
options assumed by BroadVision.

REPRESENTATIONS AND WARRANTIES

    The merger agreement contains customary representations and warranties of
Interleaf and BroadVision relating to, among other things, certain aspects of
their respective businesses and assets and other matters. The representations
and warranties expire at the effective time.

COVENANTS; CONDUCT OF BUSINESS PRIOR TO THE MERGER

    AFFIRMATIVE COVENANTS OF INTERLEAF.  Interleaf has agreed that prior to the
effective time it will:

    - conduct its business and operations in the ordinary course and in
      accordance with past practices, use all commercially reasonable efforts to
      preserve intact its current business organization, keep available the
      services of its current officers and employees and maintain its relations
      and goodwill with all suppliers, customers, landlords, creditors,
      licensors, licensees, employees and other persons having business
      relationships with it, provide all contractually required notices,
      assurances and support relating to any of its proprietary assets to ensure
      that no contractual condition arises that could increase the likelihood of
      any transfer, disclosure or release from escrow of any source code and
      promptly notify BroadVision of any notice or other communication from any
      person alleging that consent is or may be required in connection with the
      merger and any legal proceeding commenced or, to its knowledge, threatened
      against it relating to the merger;

    - provide BroadVision with access to its personnel, assets, books, records,
      tax returns and other documents;

    - deliver to BroadVision certain financial statements and reports, any
      written materials sent by Interleaf to its stockholders, any material
      notices or other communications relating to any material contracts and any
      material notice, reports or other documents received from any governmental
      agency;

    - promptly notify BroadVision of the discovery of anything that would
      constitute a material inaccuracy in any representation or warranty made by
      Interleaf, a material breach of any covenant or obligation of Interleaf
      and anything that would make the timely satisfaction of any of the closing
      conditions impossible or unlikely or that could be deemed to have a
      material adverse effect on Interleaf;

    - use all reasonable efforts to file all notices, reports and other
      documents required to be filed with any governmental agency with respect
      to the merger, including the notifications required under the
      Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and any
      applicable foreign antitrust laws or regulations;

                                       56
<PAGE>
    - call and hold a meeting of its stockholders to vote on a proposal to
      approve the merger agreement; and

    - use reasonable efforts to take, or cause to be taken, all actions
      necessary to consummate the merger.

    Interleaf's board of directors has agreed to recommend that the Interleaf
stockholders vote for approval the merger agreement. However, at any time before
the Interleaf special meeting, Interleaf's board of directors is entitled to
withdraw or modify its recommendation that the Interleaf stockholders vote to
approve the merger agreement if certain requirements, including the following,
are satisfied:

    - an unsolicited, BONA FIDE written offer to purchase all of the outstanding
      shares of Interleaf common stock is made and is not withdrawn;

    - Interleaf satisfies certain notice requirements;

    - Interleaf's board of directors determines that the offer constitutes a
      superior offer;

    - Interleaf's board of directors determines in good faith, after taking into
      account the advice of outside legal counsel, that withdrawal or
      modification of its recommendation is required for the board of directors
      to comply with its fiduciary obligations to Interleaf stockholders under
      applicable law; and

    - Interleaf reimburses BroadVision for up to $2.0 million in merger
      expenses, including attorneys' fees, accountants' fees, financial advisory
      fees and filing fees, and pays a fee of $30.0 million to BroadVision.

For purposes of the merger agreement, the term "superior offer" means an
unsolicited, BONA FIDE written offer made by a third party to purchase all of
the outstanding shares of Interleaf common stock on terms that Interleaf's board
of directors determines, in its reasonable judgment, based upon advice of an
independent financial advisor of nationally recognized reputation, to be more
favorable to Interleaf stockholders than the merger, which offer is financed or
is reasonably capable of being financed.

    NEGATIVE COVENANTS OF INTERLEAF.  Interleaf has agreed that, before the
effective time, except as otherwise agreed to in writing by BroadVision, it will
not, will not agree to and will not permit any of its subsidiaries to:

      distribution in respect of any shares of capital stock or repurchase,
      redeem or otherwise reacquire any shares of capital stock or other

      maintenance polices, service policies, product modification or upgrade
      policies, personnel policies or other business policies, other than

      obtained.

Interleaf and BroadVision received notice of early termination of the waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, on February 24, 2000.

    As used in the merger agreement, "material adverse effect" means, with
respect to Interleaf, any event, violation, inaccuracy, circumstance or other
matter that individually, or when considered with all other events,
circumstances or other matters, had or could reasonably expected to have a
material adverse effect on the business, financial condition, capitalization,
assets, liabilities, operations or results of operations of Interleaf and its
subsidiaries taken as a whole or the ability of Interleaf to consummate the
merger or any of the other transactions contemplated by the merger agreement or
stock option agreement or to perform any of its obligations under the merger
agreement or stock option agreement. For purposes of determining whether there
has been a material adverse effect, one shall disregard, any change, effect,
event or occurrence relating to:

    - the merger agreement or the merger or the announcement of the merger;

    - the economy or securities markets in general;

                                       61

    - the software industry in general, and not specifically related to
      Interleaf or any of its subsidiaries; and

    - the failure, in and of itself, to meet the predictions of equity analysts.

    CONDITIONS TO THE OBLIGATION OF INTERLEAF.  The obligation of Interleaf to
complete the merger is subject to the satisfaction of the following conditions:

    - BroadVision's representations and warranties in the merger agreement must
      be true and accurate in all respects as of the date of the merger

      disregarding any inaccuracies that, considered collectively, are deemed to
      have a material adverse effect on BroadVision;

    - BroadVision must have complied in all material respects with all covenants
      and obligations required to be complied with by it under the merger
      agreement at or prior to the closing date;

    - Interleaf shall have received:

       - a tax opinion that the merger will constitute a reorganization for
         federal income tax purposes; and

       - a certificate from an executive officer of BroadVision confirming that
         certain conditions have been satisfied;

    - there shall not have occurred anything that is deemed to have a material
      adverse effect on BroadVision; and

    - all applicable waiting periods under the Hart-Scott-Rodino Antitrust
      Improvements Act of 1976, as amended, shall have expired or been
      terminated, and any consent required under any applicable foreign
      antitrust law or regulation shall have been obtained.

period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, on February 24, 2000.

    As used in the merger agreement, "material adverse effect" means, with
respect to BroadVision, any event, violation, inaccuracy, circumstance or other

subsidiaries taken as a whole or the ability of BroadVision to consummate the
merger or any of the other transactions contemplated by the merger agreement or
stock option agreement or to perform any of its obligations under the merger
agreement or stock option agreement. A decline in BroadVision's stock price, in
and of itself, shall not be deemed to have a material adverse effect. In

effect, one shall disregard any change, effect, event or occurrence relating to:

    - the merger agreement or the merger or the announcement of the merger;

    - the economy or securities markets in general;

    - the software industry in general, and not specifically related to
      BroadVision or any of its subsidiaries; and

TERMINATION OF THE MERGER AGREEMENT

    BroadVision and Interleaf may agree by mutual written consent to terminate
the merger agreement at any time before the merger is completed. In addition,
either company may terminate the merger agreement if:

    - the merger is not completed on or before July 31, 2000, unless the failure
      to consummate the merger is attributable to a failure on the part of the
      party seeking to terminate the merger agreement to perform any material
      obligation;

    - a court or government entity issues a final order prohibiting the merger;

    - the Interleaf stockholders do not approve the merger agreement, unless the
      failure to obtain their approval is attributable to a failure on the part
      of the party seeking to terminate the merger agreement to perform any
      material obligation; or

    - breaches of the other company's representations and warranties are deemed
      to have a material adverse effect on that company, that company materially
      breaches the covenants in the merger agreement and these breaches are not
      curable through the exercise of reasonable efforts, or that company is not
      using reasonable efforts to cure these breaches.

    In addition, BroadVision may terminate the merger agreement if any of the
following occur, which are each referred to as a "triggering event:"

    - Interleaf breaches its agreement not to solicit, encourage or participate
      in discussions or negotiations with respect to acquisition proposals with
      parties other than BroadVision or its agreement to hold a special meeting
      and recommend the proposal to approve the merger agreement;

    - Interleaf's board of directors withdraws its recommendation of, or
      otherwise fails to support, the proposal to approve the merger agreement,
      or recommends another acquisition proposal;

    - Interleaf enters into any letter of intent or similar agreement
      contemplating or relating to any acquisition proposal;

    - Interleaf's board of directors fails to reaffirm its recommendation of the
      proposal to approve the merger agreement within eight business days after
      BroadVision requests that reaffirmation; or

    - an acquisition proposal is publicly announced and Interleaf fails to issue
      a press release announcing its opposition to that acquisition proposal
      within eight business days.

In addition, Interleaf may terminate the merger agreement if its board of
directors approves a superior offer in compliance with the terms of the merger
agreement.

    Subject to limited exceptions, including the survival of any obligations to
pay a termination fee, if the merger agreement is terminated, then it is void.
Except as otherwise provided, there will be no liability on the part of
BroadVision, Infiniti Acquisition Sub or Interleaf to the other, and all rights
and obligations of the parties will cease. However, no party will be relieved
from its obligations with respect to any breach of the merger agreement.

EXPENSES AND TERMINATION FEES

    If the merger is abandoned because the merger agreement is terminated, all
expenses will be paid by the party incurring them, except as follows:

    - BroadVision and Interleaf will share equally all fees and expenses, other
      than attorneys' fees, incurred in connection with the filing, printing and
      mailing of this proxy statement/prospectus and the related registration
      statement on Form S-4 and the filing of all notices, reports and

                                       63
<PAGE>
      other documents required to be filed under the Hart-Scott-Rodino Antitrust
      Improvements Act of 1976, as amended, and any applicable foreign antitrust
      laws or regulations in connection with the merger; and

    - Interleaf will reimburse BroadVision for up to $2.0 million in merger
      expenses, including attorneys' fees, accountants' fees, financial advisory
      fees and filing fees, if:

       - the merger agreement is terminated because the Interleaf stockholders
         fail to approve the principal terms of the merger;

       - the merger agreement is terminated by BroadVision because a triggering
         event has occurred;

       - it is required pursuant to the terms of the merger agreement in
         connection with Interleaf's approving, endorsing, recommending or
         entering into any letter of intent or similar document or agreement
         contemplating or relating to a superior offer; or

       - it is required pursuant to the terms of the merger agreement in
         connection with its board of directors' withdrawal or modification of
         its recommendation that the Interleaf stockholders vote to approve the
         merger agreement.

    Interleaf will pay to BroadVision a termination fee of $30.0 million if:

       - the merger agreement is terminated by BroadVision because a triggering
         event has occurred;

       - it is required pursuant to the terms of the merger agreement in
         connection with Interleaf's approving, endorsing, recommending or
         entering into any letter of intent or similar document or agreement
         contemplating or relating to a superior offer; or

       - it is required pursuant to the terms of the merger agreement in
         connection with its board of directors' withdrawal or modification of
         its recommendation that the Interleaf stockholders vote to approve the
         merger agreement.

    If the merger agreement is terminated because the Interleaf stockholders do
not approve the merger agreement and at the time of the special meeting an
acquisition proposal disclosed, announced, commenced, submitted or made prior to
the special meeting is still outstanding, then Interleaf will pay to BroadVision
a termination fee in the amount of $10.0 million and if, at any time within six
months from the termination, Interleaf enters into a definitive agreement or
consummates a transaction relating to that acquisition proposal, Interleaf will
pay to BroadVision an additional termination fee in the amount of
$20.0 million.

    BroadVision will pay to Interleaf a fee of $30.0 million as liquidated
damages if Interleaf terminates the merger agreement because of a breach by
BroadVision of any of its representations, warranties or covenants in the merger
agreement.

                             STOCK OPTION AGREEMENT

    THE FOLLOWING SUMMARY DESCRIBES THE MATERIAL TERMS OF THE STOCK OPTION
AGREEMENT BETWEEN BROADVISION AND INTERLEAF, DATED AS OF JANUARY 26, 2000. THE
FULL TEXT OF THE STOCK OPTION AGREEMENT IS ATTACHED AS ANNEX B TO THIS PROXY
STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. WE ENCOURAGE YOU
TO READ THE ENTIRE STOCK OPTION AGREEMENT.

    In order to induce BroadVision to enter into the merger agreement, Interleaf
granted to BroadVision an irrevocable option to purchase newly issued shares of
Interleaf common stock representing up to 19.9% of Interleaf common stock
outstanding as of January 26, 2000. The purchase price per option share is the
lesser of $52.69 or the exchange ratio multiplied by the average of the closing
price for BroadVision common stock on the Nasdaq National Market for the 20
consecutive trading days preceding the date of notice of exercise.

PURPOSE OF THE OPTION

    The option is intended to increase the likelihood that the merger will be
completed on its agreed terms. The option could prevent an alternative
acquisition transaction with Interleaf from being accounted for as a pooling of
interests for financial accounting purposes. The option therefore may have the
effect of discouraging others from making acquisition proposals to Interleaf
before completion of the merger with BroadVision, even from others prepared to
offer greater consideration to Interleaf stockholders than BroadVision.

EXERCISABILITY OF THE OPTION

    The option may be exercised at any time after the occurrence of an event
that would allow either Interleaf or BroadVision to terminate the merger
agreement because of the following, each of which is referred to as an "exercise
event:"

    - the Interleaf stockholders do not approve the merger agreement and at the
      time of the special meeting, an acquisition proposal disclosed, announced,
      commenced, submitted or made prior to the special meeting is still
      outstanding; or

    - a triggering event has occurred.

    The option will remain in effect until the earliest of the effective time,
the date six months after the receipt by BroadVision of notice from Interleaf of
the occurrence of an exercise event or termination of the merger agreement prior
to the occurrence of an exercise event. BroadVision may exercise the option in
whole or in part at any time during the option term following the occurrence of
an exercise event.

PROFIT LIMITATION

    The stock option agreement limits the cash payment that may be received by
BroadVision pursuant to the exercise of the option and sale of the underlying
shares of Interleaf common stock. If BroadVision exercises the option, sells any
underlying shares and receives proceeds which, together with any termination
fees received by BroadVision from Interleaf, exceeds the greater of
(a) $35.0 million or (b) the product of (i) 200,000 and (ii) the average of the
closing prices of BroadVision common stock on the Nasdaq National Market for the
five consecutive trading days preceding the first occurrence of an exercise
event, then all proceeds to BroadVision in excess of that amount shall be
promptly remitted in cash by BroadVision to Interleaf.

                                       65
<PAGE>
OTHER

    The stock option agreement contains provisions governing the procedures for
exercise of the option, payment for the underlying shares and adjustments to the
number of shares and the option exercise price upon the occurrence of certain
events, such as the issuance of additional shares, stock dividends, divisions,
combinations, recapitalizations and exchanges of shares.

    The stock option agreement also requires Interleaf to repurchase the option
and any shares of Interleaf common stock issued upon the the exercise of the
option at BroadVision's request under certain circumstances. Other circumstances
require BroadVision to sell to Interleaf shares of Interleaf common stock it has
acquired upon the the exercise of the option. The stock option agreement also
mandates that BroadVision offer to sell shares of Interleaf common stock
acquired by it upon the exercise of the option to Interleaf before selling these
shares to a third party.

    Finally, the stock option agreement contains provisions obligating Interleaf
to register under the Securities Act the offer, sale and delivery by BroadVision
of shares of Interleaf common stock acquired by BroadVision upon the exercise of
the option.

footnotes, by each director and executive officer of Interleaf and by each
person or group known to the management of Interleaf to be the beneficial owner
of more than 5% of the Interleaf common stock outstanding as of February 15,
2000. This table is based upon information supplied to Interleaf by officers,
directors and principal stockholders and information set forth in Schedules 13D
and 13G filed with the Securities and Exchange Commission. Where information
regarding stockholders is based on Schedules 13D and 13G, the number of shares

as noted. Unless otherwise indicated in the footnotes to this table and subject
to community property laws where applicable and the voting agreements entered
into between the executive officers and directors of Interleaf and BroadVision,
Interleaf believes that each of the stockholders named in this table has sole

that are currently exercisable or are exercisable within 60 days of

person holding them for the purpose of computing the percentage ownership of
that person but are not treated as outstanding for the purpose of computing the
percentage ownership of any other stockholder.

                           BROADVISION AND INTERLEAF

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

    The following unaudited pro forma condensed combined financial statements
give effect to the proposed acquisition of Interleaf by BroadVision under the
purchase method of accounting as defined in APB Opinion No. 16.

    When reviewing the following pro forma information, you should note that:

    - the pro forma condensed combined balance sheet as of September 30, 1999
      assumes that the merger took place on September 30, 1999 and combines
      BroadVision's September 30, 1999 unaudited consolidated balance sheet with
      Interleaf's September 30, 1999 unaudited consolidated balance sheet;

    - the pro forma condensed combined statement of income for the fiscal year
      ended December 31, 1998 assumes the merger took place as of January 1,
      1998 and combines BroadVision's consolidated statement of income for its
      fiscal year ended December 31, 1998 with Interleaf's consolidated
      statement of operations for the comparable twelve-month period ending
      March 31, 1999; and

    - the pro forma condensed combined statement of income for the nine-month
      period ended September 30, 1999 assumes that the merger took place as of
      January 1, 1998 and combines the unaudited consolidated statement of
      income of BroadVision for the nine-month period ending September 30, 1999
      with Interleaf's unaudited consolidated statement of operations for the
      comparable nine-month period ending December 31, 1999.

    The unaudited pro forma condensed combined financial statements have been
included for illustrative purposes only, and do not reflect any cost savings and
other synergies anticipated by BroadVision's management as a result of the
merger or any nonrecurring charges directly attributable to the merger. The
unaudited pro forma condensed combined financial statements are not necessarily
indicative of the results of operations or financial position that would have
occurred had the merger been completed on the dates indicated, nor are they
necessarily indicative of future results of operations or financial position of
the consolidated company.

    The purchase price reflected in the accompanying pro forma condensed
combined financial statements has been calculated based upon an estimated fair

accompanying pro forma condensed combined financial statements at values
representing a preliminary allocation of the purchase price. BroadVision is
currently in the process of obtaining valuations for the tangible and intangible
assets of Interleaf. The effects resulting from any differences in the final
allocation of the purchase price may differ significantly from the estimates
used herein.

      NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

NOTE 1--PURCHASE PRICE ALLOCATION

    BroadVision estimates that the purchase price for the acquisition will be
approximately $801.7 million, based on an estimated fair market value of
BroadVision's common stock of $47.73 per share which was the average market
price of BroadVision common stock for the five-day period before and after the
date the merger was agreed to and announced, and the issuance of 14.210 million
shares of BroadVision common stock in exchange for all shares of Interleaf
common stock plus the fair market value of the 2.4 million BroadVision stock
options issued in exchange for the outstanding Interleaf stock options.

    The acquired assets and liabilities of Interleaf are stated in the
accompanying unaudited pro forma condensed consolidated financial statements at
values representing a preliminary allocation of purchase price. BroadVision is
currently in the process of obtaining valuations for the tangible and intangible
assets of Interleaf. The effects resulting from any differences in the final
allocation of the purchase price may differ significantly from the estimates
used herein.

    Total purchase consideration and allocation of purchase price used in the
preparation of these statements was computed as follows, (in thousands):

NOTE 2--PRO FORMA ADJUSTMENTS

    Certain pro forma adjustments have been made to the historical amounts in
the unaudited pro forma condensed consolidated financial data:

    a.) Total costs associated with the merger are estimated to be approximately
       $16.6 million. Costs to be incurred by BroadVision and Interleaf in
       connection with the merger include investment banking, legal, accounting
       and other related fees, and have been reflected in the accompanying
       unaudited pro forma condensed consolidated balance sheet as a reduction
       to cash.

    b.) Reflects (i) the issuance of 14.210 million shares of BroadVision common
       stock in exchange for all shares of Interleaf common stock based upon an
       exchange ratio of 1.0395 of BroadVision common stock for each share of
       Interleaf common stock at an estimated fair value of $47.73 per share of
       BroadVision common stock and (ii) the fair market value of 2.4 million
       BroadVision stock options issued in exchange for the outstanding
       Interleaf stock options. Also reflects the elimination of Interleaf
       equity accounts.

    c.) Excess of purchase price consideration over fair market value of
       identifiable tangible and intangible assets, including $8.6 million
       related to acquired in-process research and

       development. Due to the nature of the non-recurring charge and the rules
       governing the pro forma financial information, the charge for acquired
       in-process research and development has been reflected as a reduction of
       stockholders' equity and is excluded from the unaudited pro forma
       condensed combined statement of operations.

    d.) Estimated severance costs that will be accrued at the acquisition date
       and paid over the following year.

    e.) Amortization of intangible assets on a straight-line basis over a
       three-year life.

    f.)  Reflects the impact of common stock issued in the acquisition as if
       outstanding from the beginning of the period presented.

    g.) To eliminate the effect of stock options and other convertible
       securities that would be antidilutive to the combined company given the
       loss on a pro forma basis. Potentially dilutive securities eliminated
       totaled 20,763,000 and 28,341,000 in the year ended December 31, 1998 and
       nine months ended September 30, 1999, respectively.

                               DISSENTERS' RIGHTS

    If the merger is consummated, dissenting stockholders of Interleaf will be
entitled to have the "fair value" of their shares at the effective time of the
merger, exclusive of any element of value arising from the accomplishment or
expectation of the merger, judicially determined and paid to them provided they
comply with the provisions of Sections 85 to 98, inclusive, of the Massachusetts
Business Corporation Law, referred to as the MBCL. The rights to this
determination and payment are commonly referred to as appraisal rights or
dissenters' rights.

    The following is a brief summary of the provisions of the MBCL that set
forth the procedures for dissenting from the merger and demanding statutory
appraisal rights. This summary does not purport to be a complete statement of
the provisions of Massachusetts law relating to the rights of stockholders of
Interleaf to an appraisal of the value of their shares and is qualified in its
entirety by reference to Sections 85 to 98 of the MBCL, the text of which is
attached to this proxy statement/prospectus as Annex E.

    Stockholders of Interleaf electing to exercise their appraisal rights under
the MBCL must file with Interleaf, before the vote to approve the merger
agreement, a written objection to the merger stating that they intend to demand
payment for their Interleaf common stock if the merger is consummated, and they
must not vote for adoption of the merger agreement. If a stockholder returns a
signed proxy card but does not specify a vote against approval of the merger
agreement or a direction to abstain, the proxy will be voted for approval of the
merger agreement and that stockholder will have waived any applicable appraisal
rights.

    A demand for appraisal must be executed by or for the stockholder of record
as that stockholder's name appears on the stock certificate. If the stock is
owned of record in a fiduciary capacity, such as by a trustee, guardian or
custodian, the demand must be executed by or for the fiduciary. If the stock is
owned of record by or for more than one person, as in a joint tenancy or tenancy
in common, the demand must be executed by or for all joint owners. An authorized
agent, including an agent for two or more joint owners, may execute the demand
for appraisal for a stockholder of record; however, the agent must identify the
record owner or owners and expressly disclose the fact that, in executing the
demand, he or she is acting as agent for the record owner or owners.

    A stockholder who elects to exercise appraisal rights should mail or deliver
his or her written demand to the Clerk of Interleaf at 62 Fourth Avenue,
Waltham, Massachusetts 02451. The written demand for appraisal should specify
the stockholder's name and mailing address and that the stockholder is demanding
appraisal of his or her or its shares.

    If the merger agreement is approved at the special meeting, then within
10 days after the consummation of the merger, Interleaf must provide written
notice of the event to all stockholders who have complied with the dissenters'
rights provisions of the MBCL and have not voted for approval of the merger
agreement.

    Within 20 days after the date of mailing of the notice of consummation of
the merger, any stockholder who has satisfied the statutory dissenters' rights
requirements may deliver to Interleaf a written demand for payment for his or
her shares. Within 30 days after expiration of that 20-day period, Interleaf may
be obligated to pay to the stockholder the fair value of the stockholder's
shares. If, during that 30-day period, Interleaf and any demanding stockholder
fail to agree as to the value of the shares, either Interleaf or the stockholder
may, within four months after the expiration of the 30-day period, file a bill
in equity in Massachusetts Superior Court in Middlesex County demanding a
determination of the fair value of the shares of the dissenting stockholders. If
no bill is filed during the four-month period, the stockholder will have
forfeited his or her appraisal rights.

    Upon the filing of any appraisal rights bill by a stockholder, service of a
copy of the bill shall be made upon Interleaf which shall, within 20 days after
such service, file in the office of the court in

                                       76
<PAGE>
which the petition was filed, a duly verified list containing the names of all
stockholders who have demanded payment for their shares and with whom agreements
as to the value of their shares have not been reached by Interleaf. If the bill
shall be filed by Interleaf, the bill shall name each person.

    If a bill for an appraisal is filed in a timely fashion, after a hearing on
the bill, the court or an appointed special master will determine which
stockholders are entitled to appraisal rights and will appraise the shares owned
by those stockholders, determining the fair value of these shares as of the date
preceding the special meeting date, exclusive of any element of value arising
from the consummation or expectation of consummation of the merger, together
with a fair rate of interest to be paid from the special meeting date on the
amount determined to be the fair value. The fair value may be more or less than
the value of BroadVision common stock to be paid to other Interleaf stockholders
in the merger. The costs of the appraisal proceeding may be determined by the
court and taxed against the parties as the court deems equitable under the
circumstances.

    Under the MBCL, the appraisal remedy is an exclusive remedy and a
stockholder who does not perfect his or her appraisal rights through compliance
with the MBCL will be bound by the terms of the merger agreement, unless the
merger agreement is unlawful or fraudulent as to the stockholder. Any
stockholder contemplating the exercise of the right to demand appraisal is urged
to review carefully the text of Sections 85 to 98 of the MBCL attached to this
proxy statement/prospectus as Annex E, particularly with respect to procedural
steps required to perfect the right to appraisal. Appraisal rights may be lost
if the procedural requirements of the MBCL are not followed exactly.
Stockholders wishing to exercise their right to demand appraisal are urged to
consult legal counsel.

    Stockholders considering seeking appraisal of their shares should have in
mind that the fair value of their shares determined under the MBCL could be
more, the same or less than the consideration they would receive pursuant to the
merger agreement if they did not seek appraisal of their shares. Any stockholder
of Interleaf who has duly demanded appraisal in compliance with the MBCL will
not, after the closing of the merger, be entitled to vote for any purpose the
shares of Interleaf common stock subject to that demand or to receive payment of
dividends or other distributions on those shares, except for dividends or
distributions payable to stockholders of record at a date prior to the closing
of the merger. Any stockholder of Interleaf who has demanded appraisal, but
subsequently waives or forfeits appraisal rights, or who properly withdraws his
or her objection to the corporate action, shall have the rights of a stockholder
who did not demand appraisal of his or her shares.

                    DESCRIPTION OF BROADVISION CAPITAL STOCK

GENERAL

    The following describes certain of the provisions of the certificate of
incorporation and bylaws of BroadVision. BroadVision's certificate of
incorporation and bylaws are included as exhibits to the registration statement
of which this proxy statement/prospectus is a part. The authorized capital stock
of BroadVision consists of 500,000,000 shares of common stock, $0.0001 par
value, and 10,000,000 shares of preferred stock, $0.0001 par value.

BROADVISION COMMON STOCK

    As of March 1, 2000, there were 82,674,488 shares of common stock
outstanding held of record by 446 stockholders. The holders of common stock are
entitled to one vote for each share held of record on all matters submitted to a
vote of the stockholders. Subject to preferences that may be applicable to any
outstanding shares of the preferred stock, the holders of common stock are
entitled to receive ratably those dividends as may be declared by the board of
directors out of funds legally available for that purpose. In the event of a
liquidation, dissolution or winding up of BroadVision, holders of the common
stock are entitled to share ratably in all assets remaining after payment of
liabilities and the liquidation preferences of any outstanding shares of
preferred stock. Holders of common stock have no preemptive rights and no right
to convert their common stock into any other securities. There are no redemption
or sinking fund provisions applicable to the common stock. All outstanding
shares of common stock are, and all shares of common stock to be outstanding if
the merger is consummated will be, fully paid and nonassessable.

BROADVISION PREFERRED STOCK

    Pursuant to the restated certificate of incorporation, the board of
directors has the authority, without further action by the stockholders, to
issue up to 10,000,000 shares of preferred stock in one or more series and to
fix the designations, powers, preferences, privileges and relative
participating, optional or special rights and the qualifications, limitations or
restrictions thereof, including dividend rights, conversion rights, voting
rights, terms of redemption and liquidation preferences, any or all of which may
be greater than the rights of the common stock. The board of directors, without
stockholder approval, can issue preferred stock with voting, conversion or other
rights that could impair the voting power and other rights of the holders of
common stock. Preferred stock thus could be issued quickly with terms calculated
to delay or prevent a change in control or make removal of management more
difficult. Additionally, the issuance of preferred stock may have the effect of
decreasing the market price of the common stock and may adversely affect the
voting and other rights of the holders of common stock. No series of preferred
stock are designated, no shares of preferred stock are outstanding and
BroadVision has no current plans to issue any of the preferred stock.

TRANSFER AGENT AND REGISTRAR

    American Securities Transfer & Trust, Inc. has been appointed as the
transfer agent and registrar for the BroadVision common stock. Its telephone
number in the United States is (800) 962-4284.

                 COMPARATIVE RIGHTS OF BROADVISION STOCKHOLDERS
                           AND INTERLEAF STOCKHOLDERS

    After the merger, Interleaf's stockholders will become stockholders of
BroadVision and Interleaf stockholders' rights will cease to be defined and
governed by the MBCL and instead will be defined and governed by the Delaware
General Corporation Law, or DGCL. While the rights and privileges of
stockholders of a Delaware corporation such as BroadVision are, in many
instances, comparable to those of stockholders of a Massachusetts corporation
such as Interleaf, there are differences. Rights of Interleaf's stockholders
will no longer be defined and governed by Interleaf's restated articles of
organization, as amended, and by-laws, as amended. Instead, each stockholder
will become a new stockholder of BroadVision whose rights as a stockholder will
be defined and governed by BroadVision's certificate of incorporation and
bylaws. The following is a summary of the material differences between the
rights of holders of Interleaf common stock and the rights of holders of
BroadVision common stock at the date of this proxy statement/prospectus. These
differences arise from differences between Delaware law and Massachusetts law
and between the BroadVision certificate and the BroadVision bylaws, on the one
hand, and the Interleaf articles and the Interleaf by-laws, on the other hand.

SIZE OF THE BOARD OF DIRECTORS

    Under the MBCL law, the number of directors shall be fixed by or determined
in the manner provided in the by-laws. Enlargement in the number of directors of
a corporation generally must be approved by holders of a majority of the
outstanding shares entitled to vote on that matter, although a board of
directors may fix the exact number of directors if authorized to do so by the
by-laws. The DGCL permits a corporation's board of directors alone to change the
authorized number or range of directors by amendment of the corporation's
bylaws, unless otherwise prohibited by the corporation's certificate of
incorporation, in which case a change in the number of directors may be made
only upon approval of that change by the stockholders. In any case, no reduction
in the authorized number of directors may have the effect of removing any
director before that director's term of office expires. The ability of the board
of directors to alter the board's size without stockholder approval enables a
corporation to respond quickly to a potential opportunity to attract the
services of a qualified director or to eliminate a vacancy for which a suitable
candidate is not available.

    Interleaf's by-laws provide for a board of directors of not less than three
and not more than thirteen. The Interleaf board of directors currently consists
of six members. The BroadVision board of directors currently consists of seven
members. Directors are elected at each annual meeting of BroadVision
stockholders. The number of directors of the BroadVision board is currently set
at seven and may be fixed exclusively by one or more resolutions adopted by the
BroadVision board of directors.

CUMULATIVE VOTING

    The MBCL does not provide for cumulative voting. Under the DGCL, cumulative
voting is not mandatory, and a corporation's certificate of incorporation must
provide for cumulative voting rights if stockholders are to be entitled to such
rights. Neither Interleaf nor BroadVision has cumulative voting.

REMOVAL OF DIRECTORS

    Under the MBCL, any director or the entire board only may be removed for
cause with the approval of a majority of the outstanding shares entitled to vote
as to removal. The MBCL defines "cause" in this context to mean:

    - conviction of a felony;

                                       79
<PAGE>
    - declaration of unsound mind by order of court;

    - gross dereliction of duty;

    - commission of an act involving moral turpitude; or

    - commission of an act that constitutes intentional misconduct or knowing
      violation of the law if the act in either event results in both an
      improper substantial personal benefit and a material injury to the
      registered corporation.

Stockholders of a Delaware corporation holding a majority of the outstanding
shares entitled to vote for directors may remove a director with or without
cause, except in certain cases involving classified boards or where cumulative
voting is permitted.

    Interleaf's articles require a vote of holders of 80% of the outstanding
shares to remove directors with or without cause and provide that directors
elected by a particular class of stockholders may be removed solely by a vote of
the holders of a majority of shares of that class. These provisions are
ineffective, however, to the extent they conflict with the applicable MBCL
provision. The MBCL preempts this removal provision to the extent that it
provides for the removal of directors only for cause by vote of holders of a
majority of the outstanding shares entitled to vote on that matter. The
BroadVision bylaws provide for removal of directors with or without cause.

FILLING NEW SEATS OR VACANCIES ON THE BOARD OF DIRECTORS

    Under the MBCL, any vacancy in the board of directors, however created,
including a vacancy resulting from the enlargement of the board, may be filled
solely by the affirmative vote of a majority of the remaining directors then in
office, even though less than a quorum, unless otherwise provided in the
corporation's articles of organization or by-laws, or if the articles of
organization direct that a particular class is to fill that vacancy, in which
case any other directors elected by that class, or a sole remaining director,
shall fill that vacancy.

    Interleaf's by-laws provide that any vacancies may be filled only by the
affirmative vote of a majority of the directors then in office, even if less
than a quorum. The BroadVision certificate provides that new seats on the
BroadVision board of directors or vacancies occurring for any cause may be
filled by the affirmative vote of the majority of stockholders generally
entitled to vote in the election of directors, or by the affirmative vote of a
majority of the directors then in office, even though less than a quorum. Newly
created directorships resulting from any increase in the authorized number of
directors shall, unless the board determines by resolution that the position
shall be filled by the stockholders, be filled only by the affirmative vote of
the directors then in office, even though less than a quorum of the board.

INDEMNIFICATION AND LIMITATION OF LIABILITY

    The MBCL permits indemnification of present and former directors and
officers to the extent specified in or authorized by:

    - the articles of organization;

    - a by-law adopted by the stockholders;

    - a vote adopted by the holders of a majority of the shares of stock
      entitled to vote; or

    - in the case of officers who are not directors, the board of directors.

However, no indemnification shall be provided for any person with respect to any
matter as to which he or she shall have been adjudicated in any proceeding not
to have acted in good faith in the reasonable belief that his or her action was
in the best interests of the corporation. The statute also

                                       80
<PAGE>
provides that the absence of any express provision for indemnification shall not
limit any right of indemnification existing independently of the statute. The
MBCL provides that directors will not be personally liable for monetary damages
for breach of their fiduciary duties as directors, except liability for:

    - any breach of the duty of loyalty to the corporation or its stockholders;

    - acts or omissions not in good faith or that involve intentional misconduct
      or a knowing violation of law;

    - unlawful payments of dividends, unlawful stock repurchases or redemptions
      or unlawful loans to insiders; or

    - any transaction from which the director derived an improper personal
      benefit.

This statutory provision has no effect on any non-monetary remedies that may be
available to the corporation or its stockholders, nor does it relieve the
corporation or its officers or directors from compliance with federal or state
securities laws.

    Delaware law requires indemnification whether an action has been
successfully defended on the merits or otherwise. Delaware law generally permits
indemnification of expenses, including attorneys' fees, actually and reasonably
incurred in the defense or settlement of a derivative or third-party action,
provided there is a determination by a majority vote of a disinterested quorum
of the directors, independent legal counsel or a majority vote of a quorum of
the stockholders that the person seeking indemnification acted in good faith and
in a manner reasonably believed to be in the best interests of the corporation.
Without court approval, however, no indemnification may be made in respect of
any derivative action in which the person is adjudged liable for negligence or
misconduct in the performance of his or her duty to the corporation. Delaware
law requires indemnification of expenses when the individual being indemnified
has successfully defended any action, claim, issue or matter on the merits or
otherwise.

    Under Delaware law, expenses incurred by an officer or director in defending
an action may be paid in advance if that director or officer undertakes to repay
the amounts if it is ultimately determined that he or she is not entitled to
indemnification. In addition, Delaware law authorizes a corporation's purchase
of indemnity insurance for the benefit of its officers, directors, employees and
agents whether or not the corporation would have the power to indemnify against
the liability covered by the policy. Delaware law states that the
indemnification provided by statute shall not be deemed exclusive of any other
rights under any bylaw, agreement, vote of stockholders or of disinterested
directors or otherwise.

    Under the DGCL, a corporation may include in its certificate of
incorporation a provision that would, subject to the limitations described
below, limit or eliminate directors' liability for monetary damages for breaches
of their fiduciary duty of care. A director's liability cannot be limited or
eliminated for:

    - breaches of the duty of loyalty;

    - acts or omissions not in good faith or that involve intentional misconduct
      or a knowing violation of law;

    - the payment of unlawful dividends or expenditure of funds for unlawful
      stock purchases or redemptions; or

    - transactions from which the director derived an improper personal benefit.

In addition, the limitation of liability provisions may not restrict a
director's liability for violation of, or otherwise relieve the corporation or
its directors from, the necessity of complying with federal or state securities
laws or affect the availability of nonmonetary remedies such as injunctive
relief or rescission.

                                       81
<PAGE>
    Interleaf's by-laws provide that Interleaf shall, to the extent legally
permissible, indemnify each former or present director or officer against all
liabilities and expenses imposed upon or incurred by any of them in connection
with, or arising out of, the defense or disposition of any action, suit or other
proceeding, civil or criminal, in which he or she may be threatened or involved,
by reason of his or her having been a director or officer. However, Interleaf
may not provide any indemnification with respect to any matter as to which any
director or officer shall be finally adjudicated in an action, suit or
proceeding not to have acted in good faith in the reasonable belief that his or
her action was in Interleaf's best interests. If any action of this kind is
disposed of, on the merits or otherwise, without the disposition being adverse
to the director or officer and without an adjudication that the person did not
act in good faith in the reasonable belief that his or her action was in
Interleaf's best interests, the director or officer is entitled to
indemnification as a matter of right.

    In all other cases, indemnification shall be made as of right unless after
investigation by:

    - a majority vote of a quorum of disinterested directors;

    - if a quorum of disinterested directors is not obtainable or, even if
      obtainable, a quorum of disinterested directors so directs, written
      opinion of independent legal counsel, who may be Interleaf's regular
      counsel; or

    - a vote of the holders of a majority of outstanding stock entitled to vote,
      exclusive of stock owned by any interested directors or officers;

it shall be determined by clear and convincing evidence that the director or
officer did not act in good faith and in a manner reasonably believed to be in
or not opposed to Interleaf's best interest.

    Indemnification may include advancement of expenses of defending an action
upon receipt of an undertaking by the person indemnified to repay these advances
if it is ultimately determined that the person is not entitled to
indemnification under the by-laws. Interleaf's by-laws also state that the right
of indemnification provided in the by-laws is not exclusive of and does not
affect any other rights to which any director or officer may be entitled under
any agreement, statute, vote of stockholders or otherwise. Interleaf's
obligation to indemnify under the by-laws shall be offset to the extent of any
other source of indemnification or any otherwise applicable insurance coverage.
Interleaf has an insurance policy in place that provides coverage for its
officers and directors for claims against them with respect to actions taken in
their capacity as Interleaf's officers and directors.

    Interleaf has entered into an indemnification agreement with each of its
officers and directors. Pursuant to these agreements, Interleaf has agreed, to
the extent legally permissible, to indemnify those officers and directors
against all losses, including without limitation judgments, fines, penalties and
expenses, in which he or she may be involved by reason of his or her having been
a director or officer or by reason of any action taken or not taken in his or
her capacity as director or officer. However, no indemnification shall be
provided with respect to any matter as to which that person shall not have acted
in good faith in the reasonable belief that his or her action was in Interleaf's
best interests. If any claim, action, suit or proceeding is disposed of, on the
merits or otherwise, without the disposition being adverse to that person,
without a plea of guilty or NOLO CONTENDRE and without an adjudication that the
person did not act in good faith in the reasonable belief that his or her action
was in Interleaf's best interests, the director or officer is entitled to
indemnification as a matter of right.

    In all other cases, indemnification shall be made upon a determination that
the person's conduct was in good faith and in the reasonable belief that his
action was in Interleaf's best interests by:

    - a quorum of disinterested directors;

    - independent legal counsel, who may be Interleaf's regular counsel; or

                                       82
<PAGE>
    - the holders of a majority of outstanding stock entitled to vote (exclusive
      of stock owned by interested directors or officers).

    Under the indemnification agreement, expenses may be advanced by Interleaf
prior to any final disposition of any action upon receipt of an undertaking by
the indemnified person to repay the advances if it is ultimately determined that
the person is not entitled to indemnification under the agreement. Each
agreement provides that the right of indemnification provided in the agreement
is in addition to any rights to which the officer or director may be entitled by
other agreements or as a matter of law and shall inure to the benefit of the
heirs, executors and administrators of the indemnified person. The rights of
indemnification provided in each of the agreements are also in addition to any
rights under any insurance policy in effect, provided that to the extent any
claim is covered by any insurance policy, Interleaf will provide coverage after
the full coverage of the insurance policy is exhausted or otherwise unavailable.

    Interleaf's articles limit the liability of Interleaf's directors to the
fullest extent permitted by law. Interleaf's articles also provide that, to the
fullest extent permitted by the MBCL, Interleaf's directors shall not be
personally liable to Interleaf or its stockholders for monetary damages for
breach of fiduciary duty as a director, notwithstanding any provision of law
imposing liability.

    The BroadVision bylaws contain provisions indemnifying BroadVision's
directors to the fullest extent permitted by Delaware law, subject to certain
limitations. BroadVision has entered into indemnification agreements with each
of its directors. The indemnification agreements provide the directors with
further indemnification to the maximum extent permitted under Delaware law.
BroadVision also has obtained directors' and officers' insurance to insure its
directors and officers against certain liabilities, including liabilities under
the securities laws. The BroadVision certificate eliminates the liability of
directors to BroadVision or its stockholders for monetary damages for breach of
fiduciary duty as a director to the fullest extent permissible under Delaware
law, as the law exists currently and as it may be amended in the future.

INTERESTED DIRECTOR TRANSACTIONS

    Under Delaware law, certain contracts or transactions between the
corporation and one or more of its directors or officers, or between a Delaware
corporation and any other corporation, partnership, association or other
organization in which one or more of its directors or officers are directors or
officers or have a financial interest, is not void or voidable solely for that
reason or solely because the interested director or officer was present at or
participates in the board or board committee meeting that authorizes the
contract or transaction, or solely because the director's or officer's votes are
counted for that purpose, if:

    - the material facts as to the director's or officer's relationship or
      interest and as to the contract or transaction are disclosed or known to
      the board of directors or committee, and the board or committee in good
      faith authorizes the contract or transaction by the affirmative votes of a
      majority of the disinterested directors, even though the disinterested
      directors constitute less than a quorum; or

    - the material facts as to the director's or officer's relationship or
      interest and as to the contract or transaction are disclosed or known to
      the stockholders entitled to vote on the contract or transaction, and the
      contract or transaction is specifically approved in good faith by vote of
      the stockholders; or

    - the contract or transaction is fair as to the corporation as of the time
      it is authorized, approved or ratified by the board of directors, a board
      committee or the stockholders.

    Massachusetts has no comparable statutory provisions to these Delaware
provisions. Interleaf's articles and by-laws do not address this issue.

                                       83
<PAGE>
LOANS TO OFFICERS AND EMPLOYEES

    The MBCL permits a corporation to make loans to its officers, employees and
directors if the directors or stockholders have determined that the loan may
reasonably be expected to benefit the corporation. Under the DGCL, a corporation
may make loans to or guaranty the obligations of or otherwise assist its
officers or other employees and those of its subsidiaries, including directors
who are also officers or employees, when the loan, guaranty or assistance, in
the judgment of the directors, may reasonably be expected to benefit the
corporation.

STOCKHOLDER DERIVATIVE SUITS

    Under both the MBCL and the DGCL, a stockholder may bring a derivative
action on behalf of a corporation only if the stockholder owned stock in the
corporation at the time of transaction in question or his or her stock was
acquired thereafter by operation of law.

ELIMINATION OF ACTIONS BY WRITTEN CONSENT OF STOCKHOLDERS

    Under both the MBCL and the DGCL, stockholders may execute an action by
written consent in lieu of a stockholder meeting. In Massachusetts, no action
may be taken unless the consent is unanimous. Massachusetts law does not permit
a corporation to eliminate the ability of stockholders to take action by written
consent. Interleaf's by-laws permit stockholder action by unanimous written
consent of the holders of the outstanding shares entitled to vote. The DGCL does
not require unanimous written consent in order for an action to be taken by
stockholders without a meeting. The DGCL permits a corporation to eliminate the
ability of stockholders to take action by written consent. BroadVision's
certificate does not permit stockholder actions by written consent.

    Elimination of the ability of stockholders to act by written consent could
lengthen the amount of time required to take stockholder actions, since certain
actions by written consent are not subject to the minimum notice requirement of
a stockholders' meeting. In addition, the elimination of stockholder actions by
written consent could deter hostile takeover attempts. A holder or group of
holders controlling a majority voting interest of BroadVision's common stock
would be unable to amend the BroadVision certificate or bylaws or remove
directors pursuant to a stockholder action by written consent and instead would
have to call a stockholders' meeting and observe the notice periods determined
by the BroadVision board pursuant to the BroadVision bylaws prior to attempting
to obtain approval of any action.

POWER TO CALL SPECIAL MEETINGS OF STOCKHOLDERS

    Under the Interleaf by-laws, a special meeting of stockholders may be called
by the president, by the board of directors or upon written application of one
or more stockholders who or which are entitled to vote and hold at least 10% of
the stock entitled to vote at the meeting.

    Pursuant to the DGCL, special meetings of stockholders may be called by a
corporation's board of directors or any person or persons authorized by the
corporation's certificate of incorporation or bylaws. BroadVision's bylaws
provide that special meetings of stockholders may be called by the chairman of
the board of directors, the chief executive officer, the board of directors
pursuant to a resolution adopted by a majority of the total number of authorized
directors or the holders of shares entitled to cast not less than 10% of the
votes at the meeting. The BroadVision bylaws further provide that only business
specified in the notice of that meeting shall be conducted at a special meeting
of stockholders.

BUSINESS COMBINATIONS WITH INTERESTED STOCKHOLDERS

    Massachusetts law restricts certain business combination transactions
involving interested stockholders for a period of three years following the date
that the stockholder became an interested stockholder. An interested stockholder
is defined as any person or entity that:

    - is the beneficial owner of at least 5% of a corporation's outstanding
      voting stock;

    - is an affiliate or associate of the corporation and was the owner of 5% or
      more of the outstanding voting stock of the corporation at any time in the
      past three years; or

    - is an affiliate of any beneficial owner or affiliate or associate that is
      an interested stockholder.

This provision applies to all corporations except those that have expressly
elected to not be governed by it. Because Interleaf has not made this election,
the interested stockholder provision applies to Interleaf.

    Under Section 203 of DGCL, certain "business combinations" with "interested
stockholders" of Delaware corporations are subject to a three-year moratorium
unless specified conditions are met. Under Section 203, certain business
combinations with a majority stockholder require the delivery of a fairness
opinion.

    Section 203 prohibits a Delaware corporation from engaging in a business
combination with an interested stockholder for three years following the date
that the person becomes an interested stockholder. With certain exceptions, an
interested stockholder is a person or group that owns 15% or more of the
corporation's outstanding voting stock, including both rights to acquire stock
under an option, warrant, agreement, arrangement or understanding or upon the
exercise of conversion or exchange rights and stock with respect to which the
person or group has voting rights only, or is an affiliate or associate of the
corporation and was the owner of 15% or more of the voting stock at any time
within the previous three years.

    For purposes of Section 203, the term "business combination" is defined
broadly to include mergers with or caused by the interested stockholder; sales
or other dispositions to the interested stockholder, except proportionately with
the corporation's other stockholders, of assets of the corporation or a
subsidiary equal to 10% or more of the total market value of the corporation's
consolidated assets or its outstanding stock; the issuance or transfer by the
corporation or a subsidiary of stock of the corporation or the subsidiary to the
interested stockholder, except for transfers in a conversion or exchange or a
pro rata distribution or certain other transactions, none of which increase the
interested stockholder's proportionate ownership of any class or series of stock
of the corporation or that subsidiary; or receipt by the interested stockholder
of the benefit, except proportionately as a stockholder, directly or indirectly,
of any loans, advances, guarantees, pledges or other financial benefits provided
by or through the corporation or a subsidiary.

    The three-year moratorium imposed on business combinations by Section 203
does not apply if:

    - before the stockholder becomes an interested stockholder, the board of
      directors approves either the business combination or the transaction that
      resulted in the person becoming an interested stockholder;

    - the interested stockholder owns 85% of the corporation's voting stock upon
      completion of the transaction that made him or her an interested
      stockholder, excluding from the 85% calculation shares owned by directors
      who are also officers of the target corporation and shares held by
      employee stock plans that do not permit employees to decide confidentially
      whether to accept a tender or exchange offer; or

                                       85
<PAGE>
    - after the person becomes an interested stockholder, the board approves the
      business combination, and it is also approved at a stockholder meeting by
      66 2/3% of the voting stock not owned by the interested stockholder.

    Section 203 only applies to Delaware corporations that, like BroadVision,
have a class of voting stock listed on a national securities exchange, quoted on
an interdealer quotation system such as the Nasdaq National Market or held of
record by more than 2,000 stockholders. However, a Delaware corporation may
elect not to be governed by Section 203 in its original certificate of
incorporation or by certain amendments to its certificate of incorporation or
bylaws. BroadVision has not made this election, and therefore, Section 203
applies to BroadVision.

    Section 203 has been challenged in lawsuits arising out of takeover
disputes, and it is not clear whether and to what extent its constitutionality
ultimately will be upheld by the courts. Although the United States District
Court for the District of Delaware has consistently upheld the constitutionality
of Section 203, the Delaware Supreme Court has not yet considered the issue.
BroadVision believes that so long as the constitutionality of Section 203 is
upheld, Section 203 will encourage any potential acquirer to negotiate with the
BroadVision board. Section 203 also has the effect of limiting the ability of a
potential acquirer to make a two-tiered bid for BroadVision in which all
stockholders would not be treated equally. Interleaf shareholders should note
that the application of Section 203 to BroadVision will confer upon the
BroadVision board the power to reject a proposed business combination even
though a potential acquirer offered a substantial premium for BroadVision's
shares over the then-current market price, assuming the stock is then publicly
traded. Section 203 also may discourage certain potential acquirers unwilling to
comply with its provisions.

    Interleaf's articles contain a "fair price provision" that restricts some
business combinations involving an interested stockholder, defined to include a
person or entity that is the beneficial owner of at least 10% of the outstanding
voting stock of Interleaf or that had been such an owner at any time during the
past two years, or an affiliate of that person or entity. The "fair price
provision" dictates a minimum price, specific form of consideration and
procedural requirements for certain business combinations involving interested
stockholders. If the fair price requirements are not met, the affirmative vote
of holders of 80% of the outstanding shares entitled to vote is required to
approve the business combination. The "fair price provision" applies only to
business combinations involving 10% stockholders.

SHARE RESTRICTED FROM VOTING

    Massachusetts law also provides that any person who acquires 20% or more of
the outstanding voting stock of a corporation may not vote his or her stock
unless the stockholders of the corporation authorize the person to do so at an
annual or special meeting of stockholders. This provision applies to all
corporations except those that have expressly elected to not be governed by the
chapter. Because Interleaf has not made this election, this provision applies to
Interleaf.

SALE OF ASSETS AND MERGERS

    The MBCL generally provides that a vote of holders of two-thirds of the
shares of each class of stock outstanding and entitled to vote thereon is
required to authorize a sale, lease or exchange of all or substantially all of a
corporation's property and assets or a merger of the corporation with or into
any other corporation, unless the articles of organization require a lesser
amount. The MBCL does not require a stockholder vote of the surviving
corporation in a merger if:

    - the agreement of merger does not change the name, the amount of shares
      authorized of any class of stock or other provisions of the articles of
      organization of the corporation;

                                       86
<PAGE>
    - the authorized unissued shares or shares held in the treasury of the
      corporation of any class of stock of the corporation to be issued or
      delivered pursuant to the agreement of merger do not exceed 15% of the
      shares of the corporation of the same class outstanding immediately prior
      to the effective date of the merger; and

    - the issuance by vote of the directors pursuant to the agreement of merger
      is authorized by the by-laws or a vote of the stockholders.

    Delaware law generally requires that a majority of the outstanding shares of
each of the acquiring and target corporations that are constituent corporations
in a statutory merger approve the merger. Delaware law does not require a
stockholder vote of the surviving corporation in a merger if:

    - the merger agreement does not amend the existing certificate of
      incorporation;

    - each share of the surviving corporation outstanding before the merger is
      an identical outstanding share after the merger; and

    - the number of shares to be issued by the surviving corporation in the
      merger does not exceed 20% of the shares outstanding immediately before
      the merger.

Delaware law also requires that a sale of all or substantially all of the assets
of a corporation be approved by a majority of the voting shares of the
corporation transferring such assets.

Interleaf's articles require the affirmative vote of holders of a majority of
the shares outstanding and entitled to vote on the question to approve a merger
or sale of all or substantially all of Interleaf's assets.

APPRAISAL RIGHTS

    Under the MBCL, a properly dissenting stockholder is entitled to receive the
appraised value of his or her shares when the corporation votes to:

    - sell, lease or exchange all or substantially all of its property and
      assets;

    - adopt an amendment to its articles of organization which adversely affects
      the rights of the stockholder; or

    - merge or consolidate with another corporation.

See "Dissenters' Rights."

    Under the DGCL, a stockholder of a corporation participating in certain
major corporate transactions may, under varying circumstances, be entitled to
dissenters' rights pursuant to which the stockholder may receive cash in the
amount of the fair market value of his or her shares in lieu of the
consideration he or she would otherwise receive in the transaction. Under the
DGCL, dissenters' rights are not available:

    - with respect to the sale, lease or exchange of all or substantially all of
      the assets of a corporation;

    - with respect to a merger or consolidation by a corporation whose shares
      either are listed on a national securities exchange or are held of record
      by more than 2,000 holders, if the stockholders receive only shares of the
      surviving corporation or shares of any other corporation that either are
      listed on a national securities exchange or are held of record by more
      than 2,000 holders, plus cash in lieu of fractional shares; or

    - to stockholders of a corporation surviving a merger if, among other
      conditions, no vote of the stockholders of the surviving corporation is
      required to approve the merger because the merger agreement does not amend
      the existing certificate of incorporation, each share of the surviving

                                       87
<PAGE>
      corporation outstanding prior to the merger is an identical outstanding or
      treasury share after the merger, and the number of shares to be issued in
      the merger does not exceed 20% of the shares of the surviving corporation
      outstanding immediately prior to the merger.

    THIS SUMMARY OF THE MATERIAL DIFFERENCES IN THE CORPORATION LAWS OF
MASSACHUSETTS AND DELAWARE, THE INTERLEAF ARTICLES, THE BROADVISION CERTIFICATE,
THE INTERLEAF BY-LAWS AND THE BROADVISION BYLAWS DOES NOT PURPORT TO BE A
COMPLETE LISTING OF DIFFERENCES IN THE RIGHTS AND REMEDIES OF HOLDERS OF SHARES
OF MASSACHUSETTS AS OPPOSED TO DELAWARE CORPORATIONS AND STOCKHOLDERS OF
INTERLEAF AND STOCKHOLDERS OF BROADVISION IN PARTICULAR. THE DIFFERENCES CAN BE
DETERMINED IN FULL BY REFERENCE TO MASSACHUSETTS LAW, TO DELAWARE LAW, THE
INTERLEAF ARTICLES, THE BROADVISION CERTIFICATE, THE INTERLEAF BY-LAWS AND THE
BROADVISION BYLAWS. THE LAWS OF MASSACHUSETTS AND DELAWARE PROVIDE THAT SOME OF
THE STATUTORY PROVISIONS AS THEY AFFECT VARIOUS RIGHTS OF HOLDERS OF SHARES MAY
BE MODIFIED BY PROVISIONS IN THE ARTICLES OF ORGANIZATION FOR MASSACHUSETTS
CORPORATIONS, CERTIFICATE OF INCORPORATION FOR DELAWARE CORPORATIONS, BY-LAWS OR
BYLAWS OF THE CORPORATION.

    It is expected that representatives of PricewaterhouseCoopers LLP will be
present at the special meeting to respond to appropriate questions of

           (v) (x) the Finpiave Warrant (as defined in Section 2.3(b)), to the
       extent outstanding immediately prior to the Effective Time, shall be
       converted into the right to receive, upon the exercise thereof, the
       number of shares of Parent Common Stock that the holder thereof would
       have received had such holder exercised the Finpiave Warrant immediately
       prior to the Effective Time and the shares of Company Common Stock that
       would have been held by such holder upon such exercise were converted
       into Parent Common Stock pursuant to this Section 1.5; and (y) each of
       the Series D Warrants (as defined in Section 2.3(b)), to the extent
       outstanding immediately prior to the Effective Time, shall be converted
       into the right to receive, upon the exercise thereof, the number of
       shares of Parent Common Stock that the holder thereof would have received
       had such holder exercised such Series D Warrant and elected to convert
       the shares of Series D (as defined in Section 2.3(b)) issuable upon such
       exercise, in each case, immediately prior to the Effective Time, and the
       shares of Company Common Stock that would have been held by such holder
       upon such exercise and conversion were converted into Parent Common Stock
       pursuant to this Section 1.5.

The fraction of a share of Parent Common Stock specified in clause "(iii)" of
the preceding sentence (as such fraction may be adjusted in accordance with
Section 1.5(b)) is referred to as the "Exchange Ratio."

        (b) If, between the date of this Agreement and the Effective Time, the
    outstanding shares of Company Common Stock or Parent Common Stock are
    changed into a different number or class of shares by reason of any stock
    split, division or subdivision of shares, stock dividend, reverse

                                      A-2
<PAGE>
    stock split, reclassification, recapitalization or other similar
    transaction, then the Exchange Ratio shall be appropriately adjusted.

        (c) If any shares of Company Common Stock outstanding immediately prior
    to the Effective Time are unvested or are subject to a repurchase option,
    risk of forfeiture or other condition under any applicable restricted stock
    purchase agreement or other agreement with the Company or under which the
    Company has any rights, then, unless the terms governing such Company Common
    Stock provide that such restriction, repurchase right or risk of forfeiture
    will be automatically waived in connection with the transactions
    contemplated by this Agreement, the shares of Parent Common Stock issued in
    exchange for such shares of Company Common Stock will also be unvested and
    subject to the same repurchase option, risk of forfeiture or other
    condition, and the certificates representing such shares of Parent Common
    Stock may accordingly be marked with appropriate legends.

        (d) No fractional shares of Parent Common Stock shall be issued in
    connection with the Merger, and no certificates or scrip for any such
    fractional shares shall be issued. Any holder of Company Common Stock who
    would otherwise be entitled to receive a fraction of a share of Parent
    Common Stock (after aggregating all fractional shares of Parent Common Stock
    issuable to such holder) shall, in lieu of such fraction of a share and upon
    surrender of such holder's Company Stock Certificate(s) (as defined in
    Section 1.6), be paid in cash the dollar amount (rounded to the nearest
    whole cent), without interest, determined by multiplying such fraction by
    the closing price of a share of Parent Common Stock on the Nasdaq National
    Market on the date the Merger becomes effective.

    1.6  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At the Effective Time:
(a) all shares of Company Common Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist, and all holders of certificates representing shares of Company Common
Stock that were outstanding immediately prior to the Effective Time shall cease
to have any rights as stockholders of the Company; and (b) the stock transfer
books of the Company shall be closed with respect to all shares of Company
Common Stock outstanding immediately prior to the Effective Time. No further
transfer of any such shares of Company Common Stock shall be made on such stock
transfer books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any shares of Company Common Stock (a
"Company Stock Certificate") is presented to the Exchange Agent (as defined in
Section 1.7) or to the Surviving Corporation or Parent, such Company Stock
Certificate shall be canceled and shall be exchanged as provided in
Section 1.7.

    1.7  EXCHANGE OF CERTIFICATES.

        (a) On or prior to the Closing Date, Parent shall select a reputable
    bank or trust company to act as exchange agent in the Merger (the "Exchange
    Agent"). Promptly after the Effective Time, Parent shall deposit with the
    Exchange Agent (i) certificates representing the shares of Parent Common
    Stock issuable pursuant to this Section 1, and (ii) cash sufficient to make
    payments in lieu of fractional shares in accordance with Section 1.5(d). The
    shares of Parent Common Stock and cash amounts so deposited with the
    Exchange Agent, together with any dividends or distributions received by the
    Exchange Agent with respect to such shares, are referred to collectively as
    the "Exchange Fund."

        (b) As soon as reasonably practicable after the Effective Time, Parent
    will cause the Exchange Agent will mail to the record holders of Company
    Stock Certificates (i) a letter of transmittal in customary form and
    containing such provisions as Parent may reasonably specify (including a
    provision confirming that delivery of Company Stock Certificates shall be
    effected, and risk of loss and title to Company Stock Certificates shall
    pass, only upon delivery of such Company Stock Certificates to the Exchange
    Agent), and (ii) instructions for use in effecting the surrender of Company
    Stock Certificates in exchange for certificates representing Parent Common
    Stock.

                                      A-3
<PAGE>
    Upon surrender of a Company Stock Certificate to the Exchange Agent for
    exchange, together with a duly executed letter of transmittal and such other
    documents as may be reasonably required by the Exchange Agent or Parent,
    (A) the holder of such Company Stock Certificate shall be entitled to
    receive in exchange therefor a certificate representing the number of whole
    shares of Parent Common Stock that such holder has the right to receive
    pursuant to the provisions of Section 1.5 (and cash in lieu of any
    fractional share of Parent Common Stock), and (B) the Company Stock
    Certificate so surrendered shall be canceled. Until surrendered as
    contemplated by this Section 1.7(b), each Company Stock Certificate shall be
    deemed, from and after the Effective Time, to represent only the right to
    receive shares of Parent Common Stock (and cash in lieu of any fractional
    share of Parent Common Stock) as contemplated by Section 1. If any Company
    Stock Certificate shall have been lost, stolen or destroyed, Parent may, in
    its discretion and as a condition precedent to the issuance of any
    certificate representing Parent Common Stock, require the owner of such
    lost, stolen or destroyed Company Stock Certificate to provide an
    appropriate affidavit and to deliver a bond (in such sum as Parent may
    reasonably direct) as indemnity against any claim that may be made against
    the Exchange Agent, Parent or the Surviving Corporation with respect to such
    Company Stock Certificate.

        (c) No dividends or other distributions declared or made with respect to
    Parent Common Stock with a record date after the Effective Time shall be
    paid to the holder of any unsurrendered Company Stock Certificate with
    respect to the shares of Parent Common Stock that such holder has the right
    to receive in the Merger until such holder surrenders such Company Stock
    Certificate in accordance with this Section 1.7 (at which time such holder
    shall be entitled, subject to the effect of applicable escheat or similar
    laws, to receive all such dividends and distributions, without interest).

        (d) Any portion of the Exchange Fund that remains undistributed to
    holders of Company Stock Certificates as of the first anniversary of the
    date on which the Merger becomes effective shall be delivered to Parent upon
    demand, and any holders of Company Stock Certificates who have not
    theretofore surrendered their Company Stock Certificates in accordance with
    this Section 1.7 shall thereafter look only to Parent for satisfaction of
    their claims for Parent Common Stock, cash in lieu of fractional shares of
    Parent Common Stock and any dividends or distributions with respect to
    Parent Common Stock.

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

        (f) Neither Parent nor the Surviving Corporation shall be liable to any
    holder or former holder of Company Common Stock or to any other Person with
    respect to any shares of Parent Common Stock (or dividends or distributions
    with respect thereto), or for any cash amounts, delivered to any public
    official pursuant to any applicable abandoned property law, escheat law or
    similar Legal Requirement.

    1.8  DISSENTING SHARES.

        (a) Notwithstanding any provision of this Agreement to the contrary, the
    shares of any holder of Company Common Stock who has demanded and perfected
    appraisal rights for such shares in accordance with the MBCL and who, as of
    the Effective Time, has not effectively withdrawn or lost such appraisal
    rights (the "Dissenting Shares"), shall not be converted into or represent a
    right

                                      A-4
<PAGE>
    to receive Parent Common Stock pursuant to Section 1.5, but the holder
    thereof shall only be entitled to such rights as are granted by the MBCL.

        (b) Notwithstanding the foregoing, if any holder of shares of Company
    Common Stock who demands appraisal of such shares under the MBCL shall
    effectively withdraw the request for appraisal or lose the right to
    appraisal, then, as of the later of the Effective Time and the occurrence of
    such event, such holder's shares shall automatically be converted into and
    represent only the right to receive Parent Common Stock and cash in lieu of
    fractional shares, without interest thereon, upon surrender of the Company
    Stock Certificates representing such shares.

        (c) The Company shall give Parent (i) prompt notice of any written
    demands for appraisal of any shares of Company Common Stock, withdrawals of
    such demands and any other instruments served pursuant to the MBCL and
    received by Company, which relate to any such demand for appraisal and
    (ii) the opportunity to participate in all negotiations and proceedings
    which take place prior to the Effective Time with respect to demands for
    appraisal under the MBCL. Company shall not, except with the prior written
    consent of Parent or as may be required by applicable law, voluntarily make
    any payment with respect to any demands for appraisal of Company Common
    Stock or offer to settle or settle any such demands.

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

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

adequate for the uses to which they are being put, are in good and safe
condition and repair (ordinary wear and tear excepted) and are adequate for the
conduct of the business of the Acquired Corporations in the manner in which such
business is currently being conducted.

    2.9  PROPRIETARY ASSETS.

        (a) Part 2.9(a)(i) of the Company Disclosure Schedule sets forth, with
    respect to each Proprietary Asset owned by the Acquired Corporations and
    registered with any Governmental Body or for which an application has been
    filed with any Governmental Body, (i) a brief description of such
    Proprietary Asset, and (ii) the names of the jurisdictions covered by the
    applicable registration or application. Part 2.9(a)(ii) of the Company
    Disclosure Schedule identifies and provides a brief description of all other
    Proprietary Assets owned by the Acquired Corporations that are material to
    the business of the Acquired Corporations. Part 2.9(a)(iii) of the Company
    Disclosure Schedule identifies and provides a brief description of, and
    identifies any ongoing royalty or payment obligations in excess of $10,000
    per quarter with respect to, each Proprietary Asset that is licensed or
    otherwise made available to the Acquired Corporations by any Person and is
    material to the business of the Acquired Corporations (except for any
    Proprietary Asset that is licensed to the Acquired Corporations under any
    third party software license generally available to the public or that was
    at the time the license was entered into available on substantially similar
    terms to companies that are similarly situated), and identifies the Contract
    under which such Proprietary Asset is being licensed or otherwise made
    available to such Acquired Corporation. The Acquired Corporations have good
    and valid title to all of the Acquired Corporation Proprietary Assets owned
    by the Acquired Corporations, free and clear of all Encumbrances, except for
    (i) any lien for Taxes not yet due and payable, and (ii) minor liens that
    have arisen in the ordinary course of business and that do not (individually
    or in the aggregate) materially detract from the value of the assets subject
    thereto or materially impair the operations

                                      A-9
<PAGE>
    of either of the Acquired Corporations. The Acquired Corporations have a
    valid right to use, license and otherwise exploit all Proprietary Assets
    required to be identified in Part 2.9(a)(iii) of the Company Disclosure
    Schedule subject to the terms of any applicable Contracts. Except as set
    forth in Part 2.9(a)(iv) of the Company Disclosure Schedule, none of the
    Acquired Corporations has developed jointly with any other Person any
    Acquired Corporation Proprietary Asset that is material to the business of
    the Acquired Corporations with respect to which such other Person has any
    rights. There is no Acquired Corporation Contract (with the exception of end
    user license agreements in the form previously delivered or made available
    (at the offices of Skadden, Arps, Slate, Meagher & Flom LLP or Craig
    Newfield) by the Company to Parent) pursuant to which any Person has any
    right (whether or not currently exercisable) to use, license or otherwise
    exploit any Acquired Corporation Proprietary Asset, other than Acquired
    Corporation Contracts for the distribution of products of the Acquired
    Corporations by distributors, resellers and channel partners.

        (b) The Acquired Corporations have taken reasonable measures and
    precautions to protect and maintain the confidentiality, secrecy and value
    of all material Acquired Corporation Proprietary Assets (except Acquired
    Corporation Proprietary Assets whose value would be unimpaired by
    disclosure). Without limiting the generality of the foregoing, (i) all
    current and former employees of the Acquired Corporations who are or were
    involved in, or who have contributed to, the creation or development of any
    material Acquired Corporation Proprietary Asset have executed and delivered
    to the Acquired Corporations an agreement (containing no material exceptions
    to or exclusions from the scope of its coverage) that is substantially
    identical to the form of Invention and Nondisclosure Agreement previously
    delivered by the Company to Parent, and (ii) all current and former
    consultants and independent contractors to the Acquired Corporations who are
    or were involved in, or who have contributed to, the creation or development
    of any material Acquired Corporation Proprietary Asset have executed and
    delivered to the Company an agreement (containing no material exceptions to
    or exclusions from the scope of its coverage) that is substantially
    identical to one of the two forms of Contractor Agreements previously
    delivered to Parent. No current or former employee, officer, director,
    stockholder, consultant or independent contractor has any right, claim or
    interest in or with respect to any Acquired Corporation Proprietary Asset.

        (c) To the knowledge of the Company: (i) all patents, trademark
    registrations currently used in the business of the Acquired Corporations,
    service mark registrations currently used in the business of the Acquired
    Corporations and copyright registrations held by any of the Acquired
    Corporations are valid, enforceable and subsisting; (ii) none of the
    Acquired Corporation Proprietary Assets and no Proprietary Asset that is
    currently being developed by any of the Acquired Corporations (either by
    itself or with any other Person) infringes, misappropriates or conflicts
    with any rights in any Proprietary Asset owned or used by any other Person;
    (iii) none of the products that are or have been designed, created,
    developed, assembled, manufactured or sold by any of the Acquired
    Corporations is infringing, misappropriating or making any unlawful or
    unauthorized use of any Proprietary Asset owned or used by any other Person,
    and none of such products has at any time infringed, misappropriated or made
    any unlawful or unauthorized use of, and none of the Acquired Corporations
    has received any notice or other communication (in writing or otherwise) of
    any actual, alleged, possible or potential infringement, misappropriation or
    unlawful or unauthorized use of, any Proprietary Asset owned or used by any
    other Person; (iv) no other Person is materially infringing,
    misappropriating or making any unlawful or unauthorized use of, and no
    Proprietary Asset owned or used by any other Person materially infringes or
    conflicts with, any Acquired Corporation Proprietary Asset.

        (d) The Acquired Corporation Proprietary Assets constitute all the
    Proprietary Assets necessary to enable the Acquired Corporations to conduct
    their business in the manner in which

                                      A-10
<PAGE>
    such business has been and is being conducted. None of the Acquired
    Corporations has (i) licensed any of the material Acquired Corporation
    Proprietary Assets to any Person on an exclusive basis, or (ii) entered into
    any covenant not to compete or Contract limiting its ability to exploit
    fully any material Acquired Corporation Proprietary Assets or to transact
    business in any market or geographical area or with any Person.

        (e) None of the Acquired Corporations has disclosed or delivered to any
    Person, or permitted the disclosure or delivery to any escrow agent or other
    Person, of any Acquired Corporation Source Code. No event has occurred, and
    no circumstance or condition exists, that (with or without notice or lapse
    of time) will, or could reasonably be expected to, result in the disclosure
    or delivery to any Person of any Acquired Corporation Source Code. Part
    2.10(a)(ii) of the Company Disclosure Schedule identifies each Contract
    pursuant to which the Company has deposited or is required to deposit with
    an escrowholder or any other Person any Acquired Corporation Source Code,
    and further describes whether the execution of this Agreement or the
    consummation of any of the transactions contemplated hereby could reasonably
    be expected to result in the release or disclosure of any Acquired
    Corporation Source Code.

        (f) To the knowledge of the Company, each computer, computer program and
    other item of software (whether installed on a computer or on any other
    piece of equipment, including firmware) that is currently used by any of the
    Acquired Corporations and material for their internal business operations is
    Year 2000 Compliant. To the knowledge of the Company, each computer program
    and other item of software that is currently generally offered for sale or
    otherwise made available to any Person by any of the Acquired Corporations
    is Year 2000 Compliant. For purposes of this Section 2.9, a computer,
    computer program or other item of software shall be deemed to be "Year 2000
    Compliant" only if it meets the definition of "Year 2000 Compliant" set
    forth as of the date of this Agreement on the Company's web page under the
    heading "Year 2000 Statement."

        (g) Except with respect to demonstration or trial copies and except for
    security routines intended to restrict the end-user to use within the scope
    of such end-user's license, no product, system, program or software module
    designed, developed, sold, licensed or otherwise made available by any of
    the Acquired Corporations to any Person contains any "back door," "time
    bomb," "Trojan horse," "worm," "drop dead device," "virus" or other software
    routines or hardware components designed by or on behalf of any Acquired
    Corporation to permit unauthorized access or to disable or erase software,
    hardware or data without the consent of the user.

    2.10  CONTRACTS.

        (a) Part 2.10 of the Company Disclosure Schedule identifies each
    Acquired Corporation Contract that constitutes a "Material Contract." For
    purposes of this Agreement, each of the following shall be deemed to
    constitute a "Material Contract":

           (i) any Contract (A) pursuant to which any of the Acquired
       Corporations is or may become obligated to make any severance,
       termination or similar payment to any current or former officer or
       director, or (B) pursuant to which any of the Acquired Corporations is or
       may become obligated to make any bonus or similar payment (other than
       payments constituting base salary) in excess of $100,000 to any current
       or former employee or director;

           (ii) any Contract (A) relating to the acquisition, transfer,
       development, sharing or license of any Proprietary Asset (except for any
       Contract pursuant to which (1) any Proprietary Asset is licensed to the
       Acquired Corporations under any third party software license which is or
       was at the time the license was entered into generally available to the
       public or that is or was at the time the license was entered into
       available on substantially similar terms to companies

                                      A-11
<PAGE>
       that are similarly situated, or (2) any Proprietary Asset is licensed by
       any of the Acquired Corporations to any Person on a non-exclusive basis),
       or (B) of the type required to be set forth in Part 2.9 of the Company
       Disclosure Schedule;

          (iii) any Contract that provides for indemnification of any officer,
       director, employee or agent;

           (iv) any Contract imposing any restriction on the right or ability of
       any Acquired Corporation (A) to compete with any other Person, (B) to
       acquire any product or other asset or any services from any other Person,
       (C) to develop, sell, supply, distribute, offer, support or service any
       product or any technology or other asset to or for any other Person or
       (D) to perform services for any other Person;

           (v) any Contract relating to any currency hedging;

           (vi) any Contract to which any Governmental Body is a party;

          (vii) any other Contract, the breach of which by any Acquired
       Corporation could reasonably be expected to have a Material Adverse
       Effect on the Acquired Corporations.

The Company has delivered or made available (at the offices of Skadden, Arps,
Slate, Meagher & Flom LLP or Craig Newfield) to Parent an accurate and complete
copy of each Acquired Corporation Contract that constitutes a Material Contract.

        (b) Each Acquired Corporation Contract that constitutes a Material
    Contract is valid and in full force and effect, and is enforceable in
    accordance with its terms, subject to (i) laws of general application
    relating to bankruptcy, insolvency and the relief of debtors, and
    (ii) rules of law governing specific performance, injunctive relief and
    other equitable remedies.

        (c) None of the Acquired Corporations has violated or breached, or
    committed any default under, any Acquired Corporation Contract that
    constitutes a Material Contract, except for violations, breaches and
    defaults that have not had and would not reasonably be expected to have a
    Material Adverse Effect on the Acquired Corporations; and, to the knowledge
    of the Company, no other Person has violated or breached, or committed any
    default under, any Acquired Corporation Contract that constitutes a Material
    Contract, except for violations, breaches and defaults that have not had and
    would not reasonably be expected to have a Material Adverse Effect on the
    Acquired Corporations. To the knowledge of the Company, no event has
    occurred, and no circumstance or condition exists, that (with or without
    notice or lapse of time) will, or would reasonably be expected to,
    (A) result in a violation or breach of any of the provisions of any Acquired
    Corporation Contract that constitutes a Material Contract, (B) give any
    Person the right to declare a default or exercise any remedy under any
    Acquired Corporation Contract that constitutes a Material Contract,
    (C) give any Person the right to receive or require a rebate, chargeback,
    penalty or change in delivery schedule under any Acquired Corporation
    Contract that constitutes a Material Contract, (D) give any Person the right
    to accelerate the maturity or performance of any Acquired Corporation
    Contract that constitutes a Material Contract, (E) result in the disclosure,
    release or delivery of any Acquired Corporation Source Code, or (F) give any
    Person the right to cancel, terminate or modify any Acquired Corporation
    Contract that constitutes a Material Contract, except in each such case for
    defaults, acceleration rights, termination rights and other rights that have
    not had and would not reasonably be expected to have a Material Adverse
    Effect on the Acquired Corporations. Since September 30, 1999, none of the
    Acquired Corporations has received any written notice or other written
    (including electronic) communication regarding any actual or possible
    violation or breach of, or default under, any Acquired Corporation Contract
    that constitutes a Material Contract, except in each such case for defaults,
    acceleration rights, termination rights and other rights that have not had
    and would not reasonably be expected to have a Material Adverse Effect on
    the Acquired Corporations.

    2.11  SALE OF PRODUCTS; PERFORMANCE OF SERVICES.  Since September 30, 1999,
no customer or other Person has asserted or threatened in writing (including an
electronic communication) to assert any claim against any of the Acquired
Corporations (a) under or based upon any warranty provided by or on behalf of
any of the Acquired Corporations, or (b) based upon any services performed by
any of the Acquired Corporations.

(d) liabilities described in Part 2.12 of the Company Disclosure Schedule.

    2.13  COMPLIANCE WITH LEGAL REQUIREMENTS.  Each of the Acquired Corporations
is, and has at all times since January 1, 1998 been, in compliance with all
applicable Legal Requirements, except where the failure to comply with such
Legal Requirements has not had and would not reasonably be expected to have a
Material Adverse Effect on the Acquired Corporations. Since September 30, 1999,
none of the Acquired Corporations has received any written notice or other
written (including electronic) communication from any Governmental Body or other
Person regarding any actual or possible violation of, or failure to comply with,
any Legal Requirement.

    2.14  CERTAIN BUSINESS PRACTICES.  None of the Acquired Corporations, and
(to the knowledge of the Company) no director, officer, agent or employee of any
of the Acquired Corporations, has (a) used any funds for unlawful contributions,
gifts, entertainment or other unlawful expenses relating to political activity,
(b) made any unlawful payment to foreign or domestic government officials or
employees or to foreign or domestic political parties or campaigns or violated
any provision of the Foreign Corrupt Practices Act of 1977, as amended, or

        (a) The Acquired Corporations hold all Governmental Authorizations
    necessary to enable the Acquired Corporations to conduct their respective
    businesses in the manner in which such businesses are currently being
    conducted, except where the failure to hold such Governmental Authorizations
    has not had and would not reasonably be expected to have a Material Adverse
    Effect on the Acquired Corporations. All such Governmental Authorizations
    are valid and in full force and effect. Each Acquired Corporation is, and at
    all times since January 1, 1998 has been, in substantial compliance with the
    terms and requirements of such Governmental Authorizations, except where the
    failure to be in compliance with the terms and requirements of such
    Governmental Authorizations has not had and would not reasonably be expected
    to have a Material Adverse Effect on the Acquired Corporations. Since
    September 30, 1999, none of the Acquired Corporations has received any
    written notice or other written (including electronic) communication from
    any Governmental Body regarding (a) any actual or possible violation of or
    failure to comply with any term or requirement of any material Governmental
    Authorization, or (b) any actual or possible revocation, withdrawal,
    suspension, cancellation, termination or modification of any material
    Governmental Authorization.

        (b) No grant, incentive or subsidy has been provided or made available
    to or for the benefit of any of the Acquired Corporations by any U.S. or
    foreign Governmental Body or otherwise.

    2.16  TAX MATTERS.

        (a) Each of the material Tax Returns required to be filed by or on
    behalf of the respective Acquired Corporations with any Governmental Body
    with respect to any taxable period ending on or before the Closing Date (the
    "Acquired Corporation Returns") (i) has been or will be filed on

                                      A-13
<PAGE>

    respects in compliance with all applicable Legal Requirements. All amounts
    shown on the Acquired Corporation Returns to be due on or before the Closing
    Date have been or will be paid on or before the Closing Date.

        (b) The Unaudited Interim Balance Sheet accrues all actual and
    contingent liabilities for Taxes with respect to all periods through
    September 30, 1999 in accordance with generally accepted accounting
    principles. Each Acquired Corporation will establish, in the ordinary course
    of business and consistent with its past practices, reserves in accordance
    with generally accepted accounting principles for the payment of all Taxes
    for the period from September 30, 1999 through the Closing Date.

        (c) No Acquired Corporation Return is currently under examination or
    audit by any Governmental Body. No extension or waiver of the limitation
    period applicable to any of the Acquired Corporation Returns has been
    granted (by the Company or any other Person) that is still in effect, and no
    such extension or waiver has been requested from any Acquired Corporation
    that is still in effect.

        (d) No claim or Legal Proceeding is pending or, to the knowledge of the
    Company, has been threatened in writing against or with respect to any
    Acquired Corporation in respect of any material Tax. There are no
    unsatisfied liabilities for material Taxes (including liabilities for
    interest, additions to tax and penalties thereon and related expenses) with
    respect to any notice of deficiency or similar document received by any
    Acquired Corporation with respect to any material Tax (other than
    liabilities for Taxes asserted under any such notice of deficiency or
    similar document which are being contested in good faith by the Acquired
    Corporations and with respect to which reserves in accordance with generally
    accepted accounting principles for payment have been established on the
    Unaudited Interim Balance Sheet). None of the Acquired Corporations has
    been, and none of the Acquired Corporations will be, required to include any
    material adjustment in taxable income for any Tax period (or portion
    thereof) pursuant to Section 481 or 263A of the Code (or any comparable
    provision of state or foreign Tax laws) as a result of transactions or
    events occurring, or accounting methods employed, prior to the Closing.

        (e) The Company has delivered to Parent all documents relevant to all
    agreements, Plans, arrangements or other Contracts covering any employee or
    independent contractor or former employee or independent contractor of any
    of the Acquired Corporations that, considered individually or considered
    collectively with any other such Contracts, will, or could reasonably be
    expected to, give rise directly or indirectly to the payment of any amount
    that would not be deductible pursuant to Section 280G or Section 162 of the
    Code (or any comparable provision under state Tax laws). With respect to the
    documents provided pursuant to the preceding sentence, the Company has
    provided to Parent the following information: (i) the name of each person
    who the Company expects to be a "disqualified individual" within the meaning
    of Section 280G(c) of the Code; and (ii) the "base amount" within the
    meaning of Section 280G(b)(3) of the Code for each such individual.

        (f) None of the Acquired Corporations is, or has ever been, a party to
    or bound by any Tax indemnity agreement, Tax sharing agreement, Tax
    allocation agreement or similar Contract.

    2.17  EMPLOYEE AND LABOR MATTERS; BENEFIT PLANS.

        (a) Part 2.17(a) of the Company Disclosure Schedule identifies each
    bonus, vacation, deferred compensation, incentive compensation, stock
    purchase, stock option, severance pay, termination pay, death and disability
    benefits, hospitalization, medical, life or other insurance, flexible
    benefits, supplemental unemployment benefits, profit-sharing, pension or
    retirement plan, program or agreement and each other employee benefit plan
    or arrangement (collectively, the

                                      A-14
<PAGE>
    "Plans") sponsored, maintained, contributed to or required to be contributed
    to by any of the Acquired Corporations for the benefit of any current or
    former employee of any of the Acquired Corporations. None of the Acquired
    Corporations is obligated to make any severance, termination or similar
    payment to any current or former employee or director in excess of six
    months of such employee's or director's salary.

        (b) None of the Acquired Corporations maintains, sponsors or contributes
    to, and none of the Acquired Corporations has at any time in the past
    maintained, sponsored or contributed to, any employee pension benefit plan
    (as defined in Section 3(2) of the Employee Retirement Income Security Act
    of 1974, as amended ("ERISA"), or any similar pension benefit plan under the
    laws of any foreign jurisdiction, whether or not excluded from coverage
    under specific Titles or Subtitles of ERISA for the benefit of employees or
    former employees of any of the Acquired Corporations (a "Pension Plan").

        (c) With respect to each Plan, the Company has delivered or made
    available (at the offices of Skadden, Arps, Slate, Meagher & Flom LLP or
    Craig Newfield) to Parent: (i) an accurate and complete copy of such Plan
    (including all amendments thereto); (ii) an accurate and complete copy of
    the annual report, if required under ERISA, with respect to such Plan for
    the last two years; (iii) an accurate and complete copy of the most recent
    summary plan description, together with each summary of material
    modifications, if required under ERISA, with respect to such Plan, (iv) if
    such Plan is funded through a trust or any third party funding vehicle, an
    accurate and complete copy of the trust or other funding agreement
    (including all amendments thereto) and accurate and complete copies the most
    recent financial statements thereof; and (v) an accurate and complete copy
    of the most recent determination letter received from the Internal Revenue
    Service with respect to such Plan (if such Plan is intended to be qualified
    under Section 401(a) of the Code).

        (d) None of the Acquired Corporations is or has ever been required to be
    treated as a single employer with any other Person under Section
    4001(b)(1) of ERISA or Section 414(b), (c), (m) or (o) of the Code, except
    for the Acquired Corporations. None of the Acquired Corporations has ever
    been a member of an "affiliated service group" within the meaning of Section
    414(m) of the Code. None of the Plans identified in the Company Disclosure
    Schedule is a multiemployer plan (within the meaning of Section 3(37) of
    ERISA) or subject to Title IV of ERISA. None of the Acquired Corporations
    has ever made a complete or partial withdrawal from a multiemployer plan, as
    such term is defined in Section 3(37) of ERISA, resulting in "withdrawal
    liability," as such term is defined in Section 4201 of ERISA (without regard
    to subsequent reduction or waiver of such liability under either Section
    4207 or 4208 of ERISA).

        (e) None of the Acquired Corporations has any binding commitment to
    create any Welfare Plan or any Pension Plan, or to modify or change any
    existing Welfare Plan or Pension Plan (other than to comply with applicable
    law) in a manner that would affect any current or former employee or
    director of any of the Acquired Corporations.

        (f) No Plan provides death, medical or health benefits (whether or not
    insured) with respect to any current or former employee or director of any
    of the Acquired Corporations after any termination of service of such
    employee or director (other than benefit coverage mandated by applicable
    law, including coverage provided pursuant to Section 4980B of the Code).

        (g) Each of the Plans has been operated and administered in all material
    respects in accordance with its terms and with applicable Legal
    Requirements, including ERISA, the Code and applicable foreign Legal
    Requirements. Part 2.17(g) of the Company Disclosure Schedule lists (i) the
    former employees of the Acquired Corporations who, as of the date of this
    Agreement, have elected continuation coverage under Section 4980B of the
    Code with respect to themselves or their dependents and (ii) the qualified
    beneficiaries (within the meaning of Section 4980B(g)(1) of

                                      A-15
<PAGE>
    the Code) under the Plans who, as of the date of this Agreement, have
    elected continuation coverage under Section 4980B of the Code.

        (h) Each of the Plans intended to be qualified under Section 401(a) of
    the Code has received a favorable determination letter from the Internal
    Revenue Service, and nothing has occurred that could reasonably be expected
    to adversely affect such determination.

        (i) Neither the execution, delivery or performance of this Agreement,
    nor the consummation of the Merger or any of the other transactions
    contemplated by this Agreement, will result in any bonus, golden parachute,
    severance or other payment or obligation to any current or former employee
    or director of any of the Acquired Corporations (whether or not under any
    Plan), or materially increase the benefits payable or provided under any
    Plan, or result in any acceleration of the time of payment or vesting of any
    such benefits. Without limiting the generality of the foregoing (and except
    as set forth in Part 2.17(i) of the Company Disclosure Schedule), the
    consummation of the Merger will not result in the acceleration of vesting of
    any unvested Company Options.

        (j) Part 2.17(j) of the Company Disclosure Schedule contains a list of
    all salaried employees of each of the Acquired Corporations as of the date
    of this Agreement, and correctly reflects, in all material respects, their
    salaries, any other compensation payable to them (including compensation
    payable pursuant to bonus, deferred compensation or commission
    arrangements), their dates of employment and their positions. None of the
    Acquired Corporations is a party to any collective bargaining contract or

    Corporations are "at will" employees.

    funded through insurance, or the book reserve established for any unfunded
    Foreign Plan, together with any accrued contributions, is sufficient to

any written notice or other written (including electronic) communication,
whether from a Governmental Body, citizens group, Employee or otherwise, that
alleges that any of the Acquired Corporations is not in compliance with any
Environmental Law, and, to the knowledge of the Company, there are no
circumstances that may prevent or interfere with the compliance by any of the
Acquired Corporations with any Environmental Law in the future. To the knowledge

site that, pursuant to any applicable Environmental Law, (1) has been placed on

insurance programs and arrangements relating to the business, assets and
operations of the Acquired Corporations are in full force and effect and, when
taken together, provide adequate insurance coverage for the business, assets and
operations of the Acquired Corporations for all risks normally insured against
by a Person carrying on the same businesses as the Acquired Corporations.

    2.20  TRANSACTIONS WITH AFFILIATES.  Between the date of the Company's last

    or that may have the effect of preventing, delaying, making illegal or

    exists that could reasonably be expected to, give rise to or serve as a

                                      A-29
<PAGE>
    Parent Common Stock, and Parent shall assume each such Company Option in
    accordance with the terms (as in effect as of the date of this Agreement) of
    the stock option plan under which it was issued and the terms of the stock
    option agreement by which it is evidenced as set forth herein. From and
    after the Effective Time, (i) each Company Option assumed by Parent may be
    exercised solely for shares of Parent Common Stock, (ii) the number of
    shares of Parent Common Stock subject to each such Company Option shall be
    equal to the number of shares of Company Common Stock subject to such
    Company Option immediately prior to the Effective Time multiplied by the
    Exchange Ratio, rounding down to the nearest whole share, (iii) the per
    share exercise price under each such Company Option shall be adjusted by
    dividing the per share exercise price under such Company Option by the
    Exchange Ratio and rounding up to the nearest cent and (iv) any restriction
    on the exercise of any such Company Option shall continue in full force and
    effect and the term, exercisability, vesting schedule and other provisions
    of such Company Option shall otherwise remain unchanged, except to the
    extent that any restriction on exercise, term, exercisability, vesting
    schedule and other provisions of such Company Option are automatically
    waived in connection with the transactions contemplated by this Agreement;
    PROVIDED, HOWEVER, that each Company Option assumed by Parent in accordance
    with this Section 5.4(a) shall, in accordance with its terms, be subject to
    further adjustment as appropriate to reflect any stock split, stock
    dividend, reverse stock split, reclassification, recapitalization or other

    Parent Common Stock issuable with respect to the Company Options assumed by
    Parent in accordance with this Section 5.4(a). Notwithstanding any of the
    foregoing to the contrary, in lieu of assuming outstanding Company Options,
    Parent may, at its election, cause such outstanding Company Options to be

    (each, a "Substitute Option"). Each Substitute Option shall (i) be
    exercisable solely for shares of Parent Common Stock, (ii) cover a number of
    shares of Parent Common Stock equal to the number of shares of Company
    Common Stock covered by the Company Option for which it is substituted,
    multiplied by the Exchange Ratio, rounded down to the nearest whole share,
    (iii) have a per share exercise price equal to the per share exercise price
    of the Company Option for which it is substituted, divided by the Exchange
    Ratio, rounded up to the nearest whole cent and (iv) have substantially
    identical terms as the Company Option for which it is substituted including,
    without limitation, any restriction on the exercise of any such Company
    Option, the term, exercisability, vesting schedule and other provisions of
    such Company Option, except to the extent that any restriction on exercise,
    term, exercisability, vesting schedule and other provisions of such Company
    Option are automatically waived in connection with the transactions
    contemplated by this Agreement; PROVIDED, HOWEVER, that each Substituted
    Option shall be subject to further adjustment as appropriate to reflect any
    stock split, stock dividend, reverse stock split, reclassification,
    recapitalization or other similar transaction subsequent to the Effective
    Time.

        (b) All actions taken by the Company and Parent pursuant to Sections
    5.4(a) and (b) above with respect to Company Options that are incentive
    stock options within the meaning of Section 422 of the Code shall not
    adversely affect the tax status of such Company Options.

        (c) Prior to the Effective Time, the Company shall take all action that
    may be necessary (under the plans pursuant to which Company Options are
    outstanding and otherwise) to effectuate the provisions of this Section 5.4
    and to ensure that, from and after the Effective Time, holders of Company
    Options have no rights with respect thereto other than those specifically
    provided in this Section 5.4.

    5.5  EMPLOYEE BENEFITS.  Parent agrees that all employees of the Acquired
Corporations who are employed by Parent, the Surviving Corporation or any
Subsidiary of the Surviving Corporation immediately after the Effective Time
("Continuing Employees") shall be eligible to continue to

                                      A-30
<PAGE>
participate in the Surviving Corporation's health and/or welfare benefit plans
in accordance with the terms of such plans, which plans shall provide benefits
not materially less favorable in the aggregate to those provided to such
employees immediately prior to the Effective Time; PROVIDED, HOWEVER, that
(a) nothing in this Section 5.5 or elsewhere in this Agreement shall limit the
right of Parent or the Surviving Corporation to amend or terminate any such
health and/or welfare benefit plan at any time, and (b) if Parent or the
Surviving Corporation terminates any such health and/or welfare benefit plan,
then, subject to any appropriate transition period, the Continuing Employees
shall be eligible to participate in Parent's health, vacation and other
non-equity based employee benefit plans, to substantially the same extent as
similarly situated employees of Parent. Nothing in this Section 5.5 or elsewhere
in this Agreement shall be construed to create a right in any employee to
employment with Parent, the Surviving Corporation or any other Subsidiary of the
Surviving Corporation and, subject to any other binding agreement between an
employee and Parent, the Surviving Corporation or any Subsidiary of the
Surviving Corporation, the employment of each Continuing Employee shall be "at
will" employment. The Company agrees to take (or cause to be taken) all actions
necessary or appropriate to terminate, effective immediately prior to the
Effective Time, any employee benefit plan sponsored by any of the Acquired
Corporations (or in which any of the Acquired Corporations participate) that
contains a cash or deferred arrangement intended to qualify under section 401(k)
of the Code. To the extent permitted by Legal Requirements, following the
Effective Time, Continuing Employees shall be eligible to participate in any
employee benefit plan sponsored by the Parent that contains a cash or deferred
arrangement intended to qualify under section 401(k) of the Code to the same
extent as other similarly situated employees of Parent. Following the Effective
Time, with respect to each plan in which any Continuing Employee participates,
for purposes of determining eligibility to participate, vesting, and entitlement
to benefits, including for severance benefits and vacation entitlement (but not
for accrual of pension benefits), service with the Acquired Corporations (or
predecessor employers to the extent the Acquired Corporations provided past
service credit) shall be treated as service with Parent, the Surviving
Corporation or any affiliate of either; provided, however, that such service
shall not be recognized to the extent that such recognition would result in a
duplication of benefits. To the extent permitted by the applicable insurance
carrier, such service also shall apply for purposes of satisfying any waiting
periods, evidence of insurability requirements, or the application of any
preexisting condition limitations. To the extent permitted by the applicable
insurance carrier, each such plan shall waive pre-existing condition limitations
to the same extent waived under the applicable plan of the Acquired Corporation.
To the extent permitted by the applicable insurance carrier, Continuing
Employees shall be given credit under the applicable plan of Parent, the
Surviving Corporation or any affiliate of either for amounts paid under a
corresponding benefit plan during the same period for purposes of applying
deductibles, copayments and out-of-pocket maximums as though such amounts had
been paid in accordance with the terms and conditions of the successor or
replacement plan.

    5.6  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

        (a) All rights to indemnification existing in favor of any Person who is
    now, or had been at any time prior to the date of this Agreement or who
    becomes prior to the Effective Time, a director and officer of the Company
    (the "Indemnified Persons") for acts and omissions occurring prior to the
    Effective Time, as provided in the Company's bylaws (as in effect as of the
    date of this Agreement) and as provided in the indemnification agreements
    between the Company and said Indemnified Persons (as in effect as of the
    date of this Agreement) in the forms disclosed by the Company to Parent
    prior to the date of this Agreement, shall survive the Merger and shall be
    observed by the Surviving Corporation to the fullest extent available under
    Massachusetts law for a period of six years from the Effective Time. Parent
    hereby guarantees the observance of such rights to indemnification by the
    Surviving Corporation.

                                      A-31
<PAGE>
        (b) From the Effective Time until the third anniversary of the Effective
    Time, the Surviving Corporation shall maintain in effect, for the benefit of
    the Indemnified Persons with respect to acts or omissions occurring prior to
    the Effective Time, the existing policy of directors' and officers'
    liability insurance maintained by the Company as of the date of this
    Agreement in the form disclosed by the Company to Parent prior to the date
    of this Agreement (the "Existing Policy"); PROVIDED, HOWEVER, that (i) the
    Surviving Corporation may substitute for the Existing Policy a policy or
    policies of comparable coverage, and (ii) the Surviving Corporation shall
    not be required to pay annual premiums for the Existing Policy (or for any
    substitute policies) in excess of $300,000 in the aggregate. In the event
    any future annual premiums for the Existing Policy (or any substitute
    policies) exceeds $300,000 in the aggregate, the Surviving Corporation shall
    be entitled to reduce the amount of coverage of the Existing Policy (or any
    substitute policies) to the amount of coverage that can be obtained for an
    annual premium equal to $300,000.

        (c) This Section 5.6 shall survive the consummation of the Merger and is
    intended to benefit and may be enforced by the Indemnified Persons and shall
    be binding on all successors and assigns of Parent and Surviving
    Corporation.

    5.7  ADDITIONAL AGREEMENTS.

        (a) Subject to Section 5.7(b), Parent and the Company shall use all
    reasonable efforts to take, or cause to be taken, all actions necessary to
    consummate the Merger and make effective the other transactions contemplated
    by this Agreement. Without limiting the generality of the foregoing, but
    subject to Section 5.7(b), each party to this Agreement (i) shall make all

    by such party in connection with the Merger and the other transactions
    contemplated by this Agreement, (ii) shall use all reasonable efforts to
    obtain each Consent (if any) required to be obtained (pursuant to any
    applicable Legal Requirement or Contract, or otherwise) by such party in
    connection with the Merger or any of the other transactions contemplated by
    this Agreement, and (iii) shall use all reasonable efforts to lift any
    restraint, injunction or other legal bar to the Merger. The Company shall
    promptly deliver to Parent a copy of each such filing made, each such notice
    given and each such Consent obtained by the Company during the Pre-Closing
    Period.

        (b) Notwithstanding anything to the contrary contained in this
    Agreement, Parent shall not have any obligation under this Agreement: (i) to
    dispose of or transfer or cause any of its Subsidiaries to dispose of or
    transfer any assets, or to commit to cause any of the Acquired Corporations
    to dispose of any assets; (ii) to discontinue or cause any of its
    Subsidiaries to discontinue offering any product or service, or to commit to
    cause any of the Acquired Corporations to discontinue offering any product
    or service; (iii) to license or otherwise make available, or cause any of
    its Subsidiaries to license or otherwise make available, to any Person, any
    technology, software or other Proprietary Asset, or to commit to cause any
    of the Acquired Corporations to license or otherwise make available to any
    Person any technology, software or other Proprietary Asset; (iv) to hold
    separate or cause any of its Subsidiaries to hold separate any assets or
    operations (either before or after the Closing Date), or to commit to cause
    any of the Acquired Corporations to hold separate any assets or operations;
    or (v) to make or cause any of its Subsidiaries to make any commitment (to
    any Governmental Body or otherwise) regarding its future operations or the
    future operations of any of the Acquired Corporations.

    5.8  DISCLOSURE.  Parent and the Company shall consult with each other
before issuing any press release or otherwise making any public statement with
respect to the Merger or any of the other transactions contemplated by this
Agreement. Without limiting the generality of the foregoing, the Company shall
not, and shall not permit any of its Representative to, make any disclosure

                                      A-36
<PAGE>
    that the condition set forth in Section 7.1 would not be satisfied, or

    "(ii)" of the proviso to the first sentence of this Section 8.3(a) shall be
    made by the Company within two business days after such termination.

        (b) If this Agreement is terminated by Parent pursuant to Section
    8.1(e) or if Section 4.3(a)(B) or Section 5.2(c) so requires, then the
    Company shall pay to Parent, within two business days after such termination
    or at the time specified in Section 4.3(a)(B) or Section 5.2(c) as
    applicable, a nonrefundable cash fee in the amount of $30,000,000. Any fee
    required to be paid pursuant to this Section 8.3(b) shall be in addition to

                                      A-37
<PAGE>
        (c) If this Agreement is terminated by Parent or the Company pursuant to
    Section 8.1(d) and at the time of the Company Stockholders' Meeting an
    Acquisition Proposal disclosed, announced, commenced, submitted or made
    prior thereto shall remain outstanding (each such Acquisition Proposal a
    "Competing Proposal"), then the Company shall pay to Parent, at the time
    specified in the next sentence, a nonrefundable cash fee in the amount of
    $10,000,000. In the case of termination of this Agreement by the Company
    pursuant to Section 8.1(d), the fee referred to in the preceding sentence
    shall be paid by the Company prior to such termination, and in the case of
    termination of this Agreement by Parent pursuant to Section 8.1(d), the fee
    referred to in the preceding sentence shall be paid by the Company within
    two business days after such termination. Any fee required to be paid
    pursuant to this Section 8.3(c) shall be in addition to any payment required
    to be made pursuant to Section 8.3(a). Immediately upon the earlier of
    entering into a definitive agreement with respect to or consummation of, at
    any time within six months after the termination of this Agreement, any
    transaction contemplated by any Competing Proposal, the Company shall pay to
    Parent an additional nonrefundable cash fee in the amount of $20,000,000.
    Any fee required to be paid pursuant to this Section 8.3(c) shall be in
    addition to any payment required to be made pursuant to Section 8.3(a).

        (d) If this Agreement is terminated pursuant to Section 8.1(g) because
    of a breach by Parent of any representation, warranty or covenant, Parent
    shall pay to the Company, within two business days after such termination, a
    cash fee in the amount of $30,000,000 as liquidated damages and as the sole
    and exclusive remedy to the Company as a result of such breach. Parent and
    the Company agree that it would be extremely difficult or impracticable to
    determine the Company's actual damages in the event of such breach and that
    the cash fee required to be paid pursuant to this Section 8.3(d) is a
    reasonable estimate of the Company's damages and not a penalty.

respective boards of directors of the Company and Parent at any time (whether

                            NONCOMPETITION AGREEMENT

    THIS NONCOMPETITION AGREEMENT is being executed and delivered as of January
26, 2000 by _______________ (the "Stockholder") in favor of, and for the benefit
of BROADVISION, INC., a Delaware corporation (the "Parent") and INTERLEAF, INC.,
a Massachusetts corporation (the "Company"). Certain capitalized terms used in
this Noncompetition Agreement are defined in Section 19.

                                    RECITALS

    A.  As a stockholder and employee of the Company, the Stockholder has
obtained extensive and valuable knowledge and confidential information
concerning the businesses of the Company and its subsidiaries. (The Company and
its subsidiaries are referred to collectively herein as the 'Acquired
Companies.')

    B.  Pursuant to an Agreement and Plan of Merger and Reorganization dated as
of January ____, 2000 (the "Reorganization Agreement"), among Parent, the
Company, and Infiniti Acquisition Sub, Inc., a wholly owned subsidiary of
Purchaser ("Merger Sub"), Merger Sub will merge with and into the Company (the
"Merger"). The Reorganization Agreement contemplates that, upon consummation of
the Merger, (i) holders of shares of the common stock of the Company will
receive shares of common stock of Parent ("Parent Common Stock") in exchange for
their shares of common stock of the Company and (ii) the Company will become a
wholly owned subsidiary of Parent. It is accordingly contemplated that
Stockholder will receive shares of Parent Common Stock in the Merger.

    C.  In connection with the Merger (and as a condition to the consummation of
the Merger), and to enable Parent to secure more fully the benefits of acquiring
the Acquired Companies as wholly owned subsidiaries, Parent has required that
the Stockholder enter into this Noncompetition Agreement; and the Stockholder is
entering into this Noncompetition Agreement in order to induce Parent to
consummate the acquisitions contemplated by the Reorganization Agreement.

    D.  Parent, the Acquired Companies and Parent's other subsidiaries have
conducted and are conducting their respective businesses on a national basis.

                                   AGREEMENT

    In order to induce Parent to consummate the transactions contemplated by the
Reorganization Agreement, and for other good and valuable consideration, the
Stockholder agrees as follows:

    1.  RESTRICTION ON COMPETITION. The Stockholder agrees that, during the
Noncompetition Period, the Stockholder shall not, and shall not permit any of
his Affiliates to:

       (A) engage in Competition in any Restricted Territory; or

       (B) be or become an officer, director, stockholder, owner, co-owner,
           Affiliate, general or limited partner, promoter, employee, agent,
           representative, consultant, advisor, manager, licensor or sublicensor
           of, for or to, or otherwise be or become associated with or acquire
           or hold (of record, beneficially or otherwise) any direct or indirect
           interest in, any Person that engages in Competition in any Restricted
           Territory; PROVIDED, HOWEVER, that the Stockholder may, without
           violating this Section 1, own, as a passive investment, shares of
           capital stock of a publicly-held corporation that engages in
           Competition if (i) such shares are actively traded on an established
           national securities market in the United States, (ii) the number of
           shares of such corporation's capital stock that are owned
           beneficially (directly or indirectly) by the Stockholder and the
           number of shares of such corporation's capital stock that are owned
           beneficially (directly or indirectly) by the Stockholder's

                                     A-C-1
<PAGE>
           Affiliates collectively represent less than three percent of the
           total number of shares of such corporation's capital stock
           outstanding, and (iii) neither the Stockholder nor any Affiliate
           (excluding any Affiliate that is an individual) of the Stockholder is
           otherwise associated directly or indirectly with such corporation or
           with any Affiliate of such corporation. Stockholder may not take or
           permit any of his Affiliates to take any action indirectly that he or
           his Affiliates are prohibited by this Agreement from taking directly.

    2.  NO HIRING OR SOLICITATION OF EMPLOYEES. The Stockholder agrees that,
during the Noncompetition Period, the Stockholder shall not, and shall not
knowingly permit any of his Affiliates to: (a) hire any Specified Employee, or
(b) directly or indirectly, personally or through others, encourage, induce,
attempt to induce, solicit or attempt to solicit (on the Stockholder's own
behalf or on behalf of any other Person) any Specified Employee to leave his or
her employment with Parent, any of the Acquired Companies or any of Parent's
other subsidiaries. (For purposes of this Section 2, 'Specified Employee' shall
mean any individual who (i) is or was an employee of any of the Acquired
Companies on the date of this Noncompetition Agreement or during the 180-day
period ending on the date of this Noncompetition Agreement, and (ii) remains or
becomes an employee of Parent, any of the Acquired Companies or any of Parent's
other subsidiaries on the date of this Noncompetition Agreement or at any time
during the 180-day period thereafter.)

    3.  CONFIDENTIALITY. The Stockholder agrees that he shall hold all
Confidential Information in strict confidence and shall not at any time (whether
during or after the Noncompetition Period): (a) reveal, report, publish,
disclose or transfer any Confidential Information to any Person (other than
Parent or any Affiliate of Parent), except in the performance of his obligations
as an employee of Parent or an Affiliate or Parent; (b) use any Confidential
Information for any purpose, except in the performance of his obligations as an
employee of Parent or an Affiliate of Parent; or (c) use any Confidential
Information for the benefit of any Person (other than Parent or any Affiliate of
Parent). Notwithstanding the above, the Stockholder shall not be in violation of
this Section 3 with regard to a disclosure that was in response to a valid order
by a court or other governmental body, provided that the Stockholder provides
Parent with prior written notice of such disclosure in order to permit Parent to
seek confidential treatment of such information.

    4.  REPRESENTATIONS AND WARRANTIES. The Stockholder represents and warrants,
to and for the benefit of Parent and the Company, that: (a) he has full power
and capacity to execute and deliver, and to perform all of his obligations
under, this Noncompetition Agreement; and (b) neither the execution and delivery
of this Noncompetition Agreement nor the performance of this Noncompetition
Agreement will result directly or indirectly in a violation or breach of (i) any
agreement or obligation by which the Stockholder or any of his Affiliates is or
may be bound, or (ii) any law, rule or regulation. The Stockholder's
representations and warranties shall survive for the Noncompetition Period;
PROVIDED, HOWEVER that nothing herein shall relieve the Stockholder from any
liability or obligation arising from any breach of a representation or warranty
during the Noncompetition Period.

    5.  SPECIFIC PERFORMANCE. The Stockholder agrees that, in the event of any
breach or threatened breach by the Stockholder of any covenant or obligation
contained in this Noncompetition Agreement, each of Parent and the Company shall
be entitled (in addition to any other remedy that may be available to it,
including monetary damages) to seek and obtain (a) a decree or order of specific
performance to enforce the observance and performance of such covenant or
obligation, and (b) an injunction restraining such breach or threatened breach.

    6.  NON-EXCLUSIVITY. The rights and remedies of Parent and the Company under
this Noncompetition Agreement are not exclusive of or limited by any other
rights or remedies which they may have, whether at law, in equity, by contract
or otherwise, all of which shall be cumulative (and not alternative). Without
limiting the generality of the foregoing, the rights and remedies of Parent and
the Company under this Noncompetition Agreement, and the obligations and
liabilities of the Stockholder

                                     A-C-2
<PAGE>
under this Noncompetition Agreement, are in addition to their respective rights,
remedies, obligations and liabilities under the law of unfair competition, under
laws relating to misappropriation of trade secrets, under other laws and common
law requirements and under all applicable rules and regulations. Nothing in this
Noncompetition Agreement shall limit any of the Stockholder's obligations, or
the rights or remedies of Parent or the Company under the Reorganization
Agreement; and nothing in the Reorganization Agreement shall limit any of the
Stockholder's obligations, or any of the rights or remedies of Parent or the
Company under this Noncompetition Agreement. No breach on the part of Parent,
the Company or any other party of any covenant or obligation contained in the
Reorganization Agreement or any other agreement shall limit or otherwise affect
any right or remedy of Parent, the Company or any of the other Indeminitees
under this Noncompetition Agreement.

    7.  SEVERABILITY. If any provision of this Noncompetition Agreement or any
part of any such provision is held under any circumstances to be invalid or
unenforceable in any jurisdiction, then (a) such provision or part thereof
shall, with respect to such circumstances and in such jurisdiction, be deemed
amended to conform to applicable laws so as to be valid and enforceable to the
fullest possible extent, (b) the invalidity or unenforceability of such
provision or part thereof under such circumstances and in such jurisdiction
shall not affect the validity or enforceability of such provision or part
thereof under any other circumstances or in any other jurisdiction, and (c) the
invalidity or unenforceability of such provision or part thereof shall not
affect the validity or enforceability of the remainder of such provision or the
validity or enforceability of any other provision of this Noncompetition
Agreement. Each provision of this Noncompetition Agreement is separable from
every other provision of this Noncompetition Agreement, and each part of each
provision of this Noncompetition Agreement is separable from every other part of
such provision.

           and governed in all respects by, the laws of the State of

           Noncompetition Agreement or the enforcement of any provision of this

               or federal court located in the County of San Francisco,

                             STOCK OPTION AGREEMENT

    THIS STOCK OPTION AGREEMENT ("Option Agreement") is entered into as of
January 26, 2000, by and between INTERLEAF, INC., a Massachusetts corporation
(the "Company"), and BROADVISION, INC., a Delaware corporation (the "Grantee").

                                    RECITALS

    A. The Grantee, Infiniti Acquisition Sub, Inc., a Massachusetts corporation
and a wholly owned subsidiary of the Grantee ("Merger Sub"), and the Company are
entering into an Agreement and Plan of Merger and Reorganization of even date
herewith (as amended from time to time, the "Reorganization Agreement") which
provides (subject to the conditions set forth therein) for the merger of Merger
Sub into the Company (the "Merger").

    B.  In order to induce the Grantee to enter into the Reorganization
Agreement, the Company has agreed to enter into this Option Agreement.

                                   AGREEMENT

    The parties to this Option Agreement, intending to be legally bound, agree
as follows:

    1.  CERTAIN DEFINITIONS.  Capitalized terms used but not defined in this
Option Agreement shall have the meanings assigned to such terms in the
Reorganization Agreement.

    2.  GRANT OF OPTION.  The Company hereby grants to the Grantee an
irrevocable option (the "Option") to purchase, out of the authorized but
unissued Company Common Stock, a number of shares of Company Common Stock equal
to up to 19.9% of the number of shares of Company Common Stock outstanding as of
the date hereof (the shares of Company Common Stock purchasable pursuant to the
Option, as adjusted as set forth herein, being referred to as the "Option
Shares"), at a price per Option Share equal to the Exercise Price. For purposes
of this Option Agreement, the applicable "Exercise Price" shall be equal to the
lesser of (a) $52.69, or (b) the Exchange Ratio, MULTIPLIED by the average of
the closing sales price of a share of Parent Common Stock as reported on the
Nasdaq National Market for the 20 consecutive trading days ending on the second
trading day preceding the Notice Date (as defined in Section 4(c)).

    3.  TERM.  The Option shall terminate on the earliest of the following dates
(the "Termination Date"): (a) the date on which the Merger becomes effective;
(b) the date on which the Reorganization Agreement is terminated pursuant to
Section 8.1 thereof, if an Exercise Event (as defined in Section 4(b)) shall not
have occurred on or prior to such date; or (c) the date six months after the
date on which the Grantee receives written notice from the Company of the
occurrence of an Exercise Event (the "Exercise Event Notice Date"); PROVIDED,
HOWEVER, that if an Exercise Event occurs, and if, by reason of any applicable
Legal Requirement, order, judgment, decree or other legal impediment, the Option
cannot be exercised on the six month anniversary of the Exercise Event Notice
Date, then the Termination Date shall be extended until the date 30 days after
the date on which such impediment is removed. The rights of the Grantee and the
obligations of the Company set forth in Sections 7, 8, 9 and 10 shall not
terminate on the Termination Date, but shall survive beyond the Termination Date
as provided in those Sections.

    4.  EXERCISE OF OPTION.

        (a) The Grantee may exercise the Option, in whole or in part, at any
    time and from time to time on or before the Termination Date following the
    occurrence of an Exercise Event. If the Grantee exercises the Option with
    respect to any Option Shares prior to the Termination Date, then,
    notwithstanding anything to the contrary contained in this Option Agreement,
    the Grantee

                                      B-1
<PAGE>
    shall be entitled to purchase such Option Shares in accordance with the
    terms of this Option Agreement after the Termination Date.

        (b) For purposes of this Option Agreement, an "Exercise Event" shall be
    deemed to have occurred if:

           (i) either the Grantee or the Company shall have the right to
       terminate the Reorganization Agreement pursuant to Section 8.1(d) thereof
       and at the time of the Company's Stockholders' Meeting an Acquisition
       Proposal disclosed, announced, commenced, submitted or made prior thereto
       shall remain outstanding; or

           (ii) the Grantee shall have the right to terminate the Reorganization
       Agreement pursuant to Section 8.1(e) thereof.

        (c) To exercise the Option with respect to any Option Shares, the
    Grantee shall deliver to the Company a written notice (an "Exercise Notice")
    specifying: (i) the number of Option Shares the Grantee will purchase;
    (ii) the place at which such Option Shares are to be purchased; and
    (iii) the date on which such Option Shares are to be purchased, which shall
    not be sooner than three business days nor later than 20 business days after
    the date of delivery of such Exercise Notice to the Company. (The date of
    delivery of such Exercise Notice to the Company is referred to as the
    applicable "Notice Date," and the Option shall be deemed to have been
    validly exercised on such Notice Date with respect to the Option Shares
    referred to in such Exercise Notice.) The closing of the purchase of such
    Option Shares (the applicable "Closing") shall take place at the place
    specified in such Exercise Notice and on the date specified in such Exercise
    Notice (the applicable "Closing Date"); PROVIDED, HOWEVER, that: (A) if such
    purchase cannot be consummated on such Closing Date by reason of any
    applicable Legal Requirement, order, judgment, decree or other legal
    impediment, then the Grantee may extend the Closing Date to a date not more
    than 20 business days after the date on which such impediment is removed;
    and (B) if prior notification to or approval of any Governmental Body is
    required, or if any waiting period must expire or be terminated, in
    connection with such purchase, then (1) the Company shall promptly cause to
    be filed any required notice or application required to be filed by the
    Company and shall use all reasonable efforts to cause such notice or
    application to be processed as expeditiously as possible, (2) the Company
    shall cooperate with the Grantee in the filing of any such notice or
    application required to be filed by the Grantee and in the obtaining of any
    such approval required to be obtained by the Grantee, and (3) the Grantee
    may extend the Closing Date to a date not more than 20 business days after
    the latest date on which any required notification has been made, any
    required approval has been obtained or any required waiting period has
    expired or been terminated.

        (d) If the Grantee receives net proceeds in connection with any sale or
    other disposition of the Option or Option Shares (including, without
    limitation, any amounts received by the Grantee pursuant to Sections 7, 8 or
    9) which, together with any proceeds received by the Grantee in connection
    with any prior such sale or disposition, any dividends or distributions
    received by the Grantee on any Option Shares and any amount paid to the
    Grantee pursuant to Sections 8.3(b) and 8.3(c) of the Reorganization
    Agreement prior thereto or thereafter, are in excess of the Threshold Amount
    (as defined herein), then all net proceeds to the Grantee in excess of the
    Threshold Amount shall be remitted to the Company promptly following receipt
    thereof. As used herein, "Threshold Amount" shall mean the amount equal to
    the greater of (i) $35,000,000 or (ii) the product of (A) 200,000 and (B)
    the average of the closing sales price of a share of Parent Common Stock as
    reported on the Nasdaq National Market for the five consecutive trading days
    ending on the first trading day preceding the first occurrence of an
    Exercise Event.

                                      B-2
<PAGE>
    5.  PAYMENT AND DELIVERY OF CERTIFICATE.

        (a) On each Closing Date, the Grantee shall pay to the Company by wire
    in immediately available funds an amount equal to the applicable Exercise
    Price MULTIPLIED by the number of Option Shares to be purchased by the
    Grantee from the Company on such Closing Date.

        (b) At each Closing, simultaneously with the delivery of the available
    funds referred to in Section 5(a), the Company shall deliver to the Grantee
    a certificate representing the Option Shares being purchased at such
    Closing. The Company represents, warrants and covenants that such Option
    Shares will be duly authorized, validly issued, fully paid, nonassessable
    and free and clear of all Encumbrances, except as may be specifically
    provided in this Option Agreement.

        (c) The certificate representing the Option Shares delivered at each
    Closing shall be endorsed with a restrictive legend that shall read
    substantially as follows:

       THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
       THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR OTHERWISE
       TRANSFERRED UNLESS REGISTERED UNDER SAID ACT OR UNLESS AN EXEMPTION FROM
       THE REGISTRATION REQUIREMENTS OF SAID ACT IS AVAILABLE.

If at any time the Grantee delivers to the Company evidence (in the form of a
copy of a letter from the staff of the SEC or an opinion of counsel reasonably
satisfactory to the Company, or in some other form) that the legend referred to
above is not required for purposes of the Securities Act, then the Company shall
promptly replace such certificate with a certificate that does not include such
legend.

    6.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION, ETC.

        (a) If the outstanding shares of Company Common Stock are changed into a
    different number or class of shares or securities by reason of any stock
    split, division or subdivision of shares, stock dividend, reverse stock
    split, reclassification, recapitalization or other similar transaction, then
    the number or class of shares or other securities subject to the Option, the
    applicable Exercise Price, the Designated Price (as defined in Section 7(c))
    and the other numbers and dollar amounts referred to in this Option
    Agreement shall be adjusted appropriately, and the Company shall ensure that
    proper provision is made in the agreements and other documents governing
    such transaction so that the Grantee shall receive upon exercise of the
    Option the same number and class of outstanding shares or other securities
    that the Grantee would have received in respect of the Company Common Stock
    if the Option had been exercised immediately prior to such transaction or
    event or the record date for determining the stockholders entitled to
    participate in such transaction or event, as applicable.

        (b) If any additional shares of Company Common Stock are issued after
    the date of this Option Agreement (other than pursuant to a transaction or
    event described in Section 6(a)), then the number of shares of Company
    Common Stock then remaining subject to the Option shall be increased to the
    number by which (i) 19.9% of the number of shares of the Company Common
    Stock outstanding after the issuance of such additional shares exceeds
    (ii) the sum of (A) the number of Option Shares purchasable under the Option
    immediately prior to the issuance of such additional shares and (B) the
    number of shares of Company Common Stock issued upon the exercise of the
    Option prior to the issuance of such additional shares.

        (c) If the Company shall enter into an agreement (i) to consolidate,
    exchange shares or merge with any Person, other than the Grantee or one of
    the Grantee's Subsidiaries, or (ii) to sell, lease or otherwise transfer all
    or substantially all of its assets to any Person, other than the Grantee or
    one of the Grantee's Subsidiaries, then the Company shall ensure that proper
    provision is made in the agreements and other documents governing such
    transaction so that the Option shall, upon the consummation of such
    transaction, become exercisable for the stock, securities,

                                      B-3
<PAGE>
    cash or other property that would have been received by the Grantee if the
    Grantee had exercised the Option immediately prior to such transaction or
    the record date for determining the stockholders entitled to participate in
    such transaction, as appropriate.

        (d) The provisions of Sections 7, 8, 9 and 10 shall apply (with
    appropriate adjustments) to any securities for which the Option becomes
    exercisable pursuant to this Section 6.

    7.  REPURCHASE AT THE REQUEST OF THE GRANTEE.

        (a) If, at any time during the period commencing upon the occurrence of
    the first Exercise Event and ending on the date six months after the
    Exercise Event Notice Date, the Grantee delivers to the Company a notice
    stating that the Grantee is exercising its rights under this Section 7, then
    the Company shall repurchase from the Grantee (i) that portion of the Option
    that then remains unexercised, (ii) all of the shares of Company Common
    Stock beneficially owned by the Grantee that were previously purchased by
    the Grantee upon exercise of the Option, and (iii) the Grantee's right to
    receive all Option Shares with respect to which the Option was previously
    exercised but which have not yet been issued and delivered to the Grantee.
    (The date on which the Grantee delivers such notice to the Company is
    referred to as the "Grantee Request Date.") Such repurchase shall be at an
    aggregate price (the "Grantee Repurchase Consideration") equal to the sum
    of:

           (i) the aggregate number of Option Shares with respect to which the
       Option has been exercised on or prior to the Grantee Request Date and
       which are beneficially owned by the Grantee, MULTIPLIED by the Designated
       Price;

           (ii) the aggregate number of Option Shares with respect to which the
       Option has been exercised on or prior to the Request Date but which have
       not, as of the Grantee Request Date been issued and delivered to the
       Grantee, MULTIPLIED by the Designated Price; and

          (iii) the number of Option Shares with respect to which the Option has
       not been exercised on or prior to the Grantee Request Date MULTIPLIED by
       the amount (if any) by which the Designated Price exceeds the applicable
       Exercise Price.

        (b) If the Grantee exercises its rights under this Section 7, then the
    Company shall, within three business days after the Grantee Request Date,
    pay the Grantee Repurchase Consideration to the Grantee in immediately
    available funds, and the Grantee shall thereupon surrender to the Company
    the certificate or certificates evidencing the shares of Company Common
    Stock repurchased by the Company pursuant to this Section 7.

        (c) For purposes of this Option Agreement, the "Designated Price" means
    the highest of (i) the highest purchase price per share paid after the date
    of this Option Agreement and on or prior to the applicable Request Date
    pursuant to any tender or exchange offer made for shares of Company Common
    Stock, (ii) the highest price per share paid or to be paid by any Person for
    shares of Company Common Stock pursuant to any agreement contemplating a
    merger or other business combination transaction involving the Company that
    was entered into after the date of this Option Agreement and on or prior to
    the applicable Request Date, (iii) the highest bid price per share of
    Company Common Stock as quoted on the Nasdaq National Market (or if Company
    Common Stock is not quoted on the Nasdaq National Market, the highest bid
    price per share of Company Common Stock as quoted on any other market
    comprising a part of the Nasdaq Stock Market or, if the shares of Company
    Common Stock are not quoted thereon, on the principal trading market (as
    defined in Regulation M under the Exchange Act) on which such shares are
    traded as reported by a recognized source) during the 90-day period ending
    on the applicable Request Date, or (iv) the highest Exercise Price paid or
    payable for any Option Shares. If any portion of the consideration paid or
    to be paid pursuant to clause "(i)" or "(ii)" of the preceding sentence is
    in a form other than cash, then the value of the non-cash portion of such
    consideration shall be determined in good faith by an independent investment
    banking firm mutually acceptable

                                      B-4
<PAGE>
    to the Company and the Grantee, and such firm's determination of such value
    shall be final and conclusive for all purposes under this Option Agreement.

        (d) The Company hereby undertakes to use reasonable efforts to obtain
    all required regulatory and legal approvals and to file any required notices
    as promptly as practicable in order to accomplish any repurchase
    contemplated by this Section 7. Nonetheless, to the extent that the Company
    is prohibited under any applicable Legal Requirement from repurchasing the
    Option or the Option Shares in full, the Company shall immediately so notify
    the Grantee and thereafter deliver or cause to be delivered, from time to
    time, to the Grantee the portion of the Grantee Repurchase Consideration
    that is required to be delivered pursuant hereto and that it is no longer
    prohibited from delivering, within three business days after the date which
    the Company is no longer so prohibited, PROVIDED, HOWEVER, that if the
    Company at any time after delivery to it of a notice of repurchase pursuant
    to Section 7(a) is prohibited under any applicable Legal Requirement from
    delivering to the Grantee the Grantee Repurchase Consideration, the Grantee
    may revoke its notice of repurchase either in whole or in part whereupon, in
    the case of revocation in part, the Company shall promptly (i) deliver to
    the Grantee that portion of the Grantee Repurchase Consideration that the
    Company is not prohibited from delivering after taking into account any such
    revocation and (ii) deliver, as appropriate, to the Grantee, either (A) a
    new agreement evidencing the right of the Grantee to purchase that number of
    shares of Company Common Stock equal to the number of shares of Company
    Common Stock purchasable immediately prior to the delivery of the notice of
    repurchase less the number of shares of Company Common Stock covered by the
    portion of the Option repurchased and/or (B) a certificate for the number of
    Option Shares covered by the revocation.

        (e) In connection with any repurchase by the Company of any portion of
    the Option or shares of Company Common Stock pursuant to this Section 7, the
    Grantee will be required to represent and warrant to the Company that the
    Grantee has good and valid title to such portion of the Option or shares of
    Company Common Stock, free and clear of all adverse claims, immediately
    prior to the consummation of such repurchase.

    8.  REPURCHASE AT THE REQUEST OF THE COMPANY.

        (a) If the Grantee has acquired Option Shares pursuant to the exercise
    of the Option, then, at any time during the period beginning six months from
    the Exercise Event Notice Date and ending 12 months from the Exercise Event
    Notice Date (the "Purchase Period"), the Company may require the Grantee,
    upon delivery to the Grantee of a notice stating that the Company is
    exercising its rights under this Section 8, to sell to the Company all, but
    not less than all, of the Option Shares held by the Grantee. (The date on
    which the Company delivers such notice to the Grantee is referred to as the
    "Company Request Date.") Such repurchase shall be at an aggregate price (the
    "Company Repurchase Consideration") equal to the sum of the aggregate number
    of Option Shares held by the Grantee MULTIPLIED by the Designated Price.

        (b) The closing of any repurchase of Option Shares pursuant to this
    Section 8 shall take place on the date designated by the Company in the
    notice delivered pursuant to Section 8(a), which date shall be no more than
    20 and no less than three business days from the Company Request Date. On
    the closing date, the Company shall pay the Company Repurchase Consideration
    to the Grantee in immediately available funds, and the Grantee shall
    thereupon surrender to the Company the certificate or certificates
    evidencing the shares of Company Common Stock repurchased by the Company
    pursuant to this Section 8.

    9.  FIRST REFUSAL.

        (a) If the Grantee desires to sell, assign, transfer or otherwise
    dispose of all or any of the shares of Company Common Stock or other
    securities acquired by it pursuant to the exercise of the Option, it will
    give the Company written notice of the proposed transaction (the "Offeror's
    Notice"), identifying the proposed transferee, the proposed purchase price
    and the terms of such proposed transaction. For 10 business days following
    receipt of such notice, the Company shall have the option to elect by
    written notice to purchase all, but not less than all, of the shares
    specified in Offeror's Notice at the price and upon the terms set forth in
    such notice.

                                      B-5
<PAGE>
        (b) The closing of any repurchase of shares of Option Shares pursuant to
    this Section 9 shall take place within 10 business days of the Company's
    election to purchase such shares. On the closing date, the Company shall pay
    the purchase price to the Grantee in immediately available funds, and the
    Grantee shall thereupon surrender to the Company the certificate or
    certificates evidencing the shares of Company Common Stock repurchased by
    the Company pursuant to this Section 9.

        (c) If the Company does not elect to purchase the shares of Company
    Common Stock or other securities designated in the Offeror's Notice, the
    Grantee may, within 60 days from the date of the Offeror's Notice sell such
    shares of Company Common Stock or other securities to the proposed
    transferee at no less than the price specified and on terms not more
    favorable than those set forth in the Offeror's Notice, PROVIDED, HOWEVER,
    that the provisions of this Section 9(c) will not limit the rights the
    Grantee may otherwise have if the Company has elected to purchase such
    shares of Company Common Stock or other securities and wrongfully refuses to
    complete such purchase.

        (d) The requirements of this Section 9 will not apply to (i) any sale,
    assignment, transfer or disposition to an affiliate of the Grantee; PROVIDED
    that such affiliate agrees to be bound by the terms hereof or (ii) any sale,
    assignment, transfer or disposition as a result of which the proposed
    transferee would own beneficially not more than 2% of the outstanding voting
    power of the Company.

    10.  REGISTRATION RIGHTS.

        (a) The Company shall, if requested by the Grantee at any time and from
    time to time within two years after the first exercise of the Option (the
    "Registration Period"), as expeditiously as practicable, prepare, file and
    cause to be declared effective up to two registration statements under the
    Securities Act (including, at the sole discretion of the Company, a "shelf"
    registration statement under Rule 415 under the Securities Act or any
    successor provision), if registration under the Securities Act is (in the
    Grantee's good faith judgment) necessary or desirable in order to permit the
    offering, sale and delivery, in accordance with the intended method of sale
    or other disposition stated by the Grantee, of any or all shares of Company
    Common Stock or other securities that have been acquired or are issuable
    upon exercise of the Option. No other securities may be included in any such
    registration statement, without the Grantee's prior written consent. The
    Company shall use all reasonable efforts to cause each such registration
    statement to become effective, to obtain all consents or waivers of other
    parties that are required therefor and to keep such registration statement
    effective for such period as may be as reasonably necessary to effect such
    sale or other disposition. In addition, the Company shall use all reasonable
    efforts to register such shares or other securities under any applicable
    state securities laws. The obligations of the Company hereunder to file a
    registration statement and to maintain its effectiveness may be suspended
    for one or more periods of time not exceeding 90 days in the aggregate if
    the Board of Directors of the Company shall have determined in good faith
    that the filing of such registration statement or the maintenance of its
    effectiveness would require disclosure of material nonpublic information and
    that the disclosure thereof would materially and adversely affect the
    Company. For purposes of determining whether two requests have been made
    under this Section 10, only requests relating to a registration statement
    that has become effective under the Securities Act and that remained
    effective for a period ending on the earlier of 180 days after becoming
    effective or until the Grantee had disposed of all shares covered thereby
    shall be counted.

        (b) The expenses associated with the preparation and filing of any
    registration statement pursuant to this Section 10 and any sale covered
    thereby (including any fees related to blue sky qualifications and filing
    fees in respect of the National Association of Securities Dealers, Inc.)
    shall be borne and paid by, and shall be for the sole account of, the
    Company (except for underwriting

                                      B-6
<PAGE>
    discounts or commissions or brokers' fees in respect to shares to be sold by
    the Grantee and the fees and disbursement of the Grantee's counsel).

        (c) The Grantee shall provide all information reasonably requested by
    the Company for inclusion in any registration statement to be filed
    hereunder. If during the Registration Period the Company shall propose to
    register under the Securities Act the offering, sale and delivery of Company
    Common Stock by the Company for cash pursuant to a firm commitment
    underwriting, it shall (without limiting the Company's other obligations
    under this Section 10) allow the Grantee the right to participate in such
    registration provided that the Grantee participates in the underwriting;
    PROVIDED, HOWEVER, that, if the managing underwriter of such offering
    advises the Company in writing that in its opinion the number of shares of
    Company Common Stock requested to be included in such registration exceeds
    the number that can be sold in such offering, the Company shall, after fully
    including therein all securities to be sold by the Company, include the
    shares requested to be included therein by the Grantee pro rata (based on
    the number of shares intended to be included therein) with the shares
    intended to be included therein by Persons other than the Company. In
    connection with any offering, sale and delivery of Company Common Stock
    pursuant to a registration effected pursuant to this Section 10, the Company
    and the Grantee shall provide each other and each underwriter of the
    offering with customary representations, warranties and covenants, including
    covenants of indemnification and contribution.

    11.  LISTING.  If, at the time of the occurrence of an Exercise Event, the
Company Common Stock (or any other class of securities subject to the Option) is
quoted on the Nasdaq National Market or quoted or listed on any other market or
exchange, then the Company, upon the occurrence of such Exercise Event, shall
promptly file an application to quote on the Nasdaq National Market and quote or
list on any such other market or exchange the shares of the Company Common Stock
(or other securities subject to the Option) and shall use its best efforts to
cause such application to be approved as promptly as practicable.

    12.  REPLACEMENT OF AGREEMENT.  Upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Option Agreement and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification, and upon surrender and cancellation of
this Option Agreement, if mutilated, the Company will execute and deliver to the
Grantee a new Option Agreement of like tenor and date.

    13.  MISCELLANEOUS.

        (A)  WAIVER.  No failure on the part of any party to exercise any power,
right, privilege or remedy under this Option Agreement, and no delay on the part
of any party in exercising any power, right, privilege or remedy under this
Option Agreement, shall operate as a waiver of such power, right, privilege or
remedy; and no single or partial exercise of any such power, right, privilege or
remedy shall preclude any other or further exercise thereof or of any other
power, right, privilege or remedy. No party shall be deemed to have waived any
claim arising out of this Option Agreement, or any power, right, privilege or
remedy under this Option Agreement, unless the waiver of such claim, power,
right, privilege or remedy is expressly set forth in a written instrument duly
executed and delivered on behalf of such party; and any such waiver shall not be
applicable or have any effect except in the specific instance in which it is
given.

        (B)  NOTICES.  Any notice or other communication required or permitted
to be delivered to any party under this Option Agreement shall be in writing and
shall be deemed properly delivered, given and received (a) when delivered by
hand or (b) two business days after being sent by registered mail or by courier
or express delivery service or by facsimile to the address or facsimile
telephone number, respectively, set forth beneath the name of such party below
(or to such other address or facsimile telephone number, respectively, as such

        (D)  BINDING EFFECT; BENEFIT; ASSIGNMENT.  This Option Agreement shall
be binding upon, and shall be enforceable by and inure solely to the benefit of,
the parties hereto and their respective successors and assigns; PROVIDED,
HOWEVER, that neither this Option Agreement nor any of the rights, interest or
obligations hereunder may be assigned by either party without the prior written
consent of the other party, and any attempted assignment of this Option
Agreement or any of such rights, interest or obligations without such consent
shall be void and of no effect. Nothing in this Option Agreement, express or
implied, is intended to or shall confer upon any Person (other than the parties
hereto and any permitted successors and assigns) any right, benefit or remedy of
any nature under or by reason of this Option Agreement.

        (E)  AMENDMENT AND MODIFICATION.  This Option Agreement may be amended
with the approval of the respective boards of directors of the Company and the
Grantee at any time. This Option Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto.

        (F)  FURTHER ACTIONS.  The Company agrees to cooperate fully with the
Grantee and to execute and deliver such further documents, certificates,
agreements and instruments and to take such other actions as may be reasonably
requested by the Grantee to evidence or reflect the transactions

                                      B-8
<PAGE>
contemplated by this Option Agreement and to carry out the intent and purposes
of this Option Agreement.

        (G)  HEADINGS.  The bold-faced headings contained in this Option
Agreement are for convenience of reference only, shall not be deemed to be a
part of this Option Agreement and shall not be referred to in connection with
the construction or interpretation of this Option Agreement.

        (H)  APPLICABLE LAW; JURISDICTION.  This Option Agreement shall be
governed by, and construed in accordance with, the laws of the State of
Delaware, regardless of the laws that might otherwise govern under applicable
principles of conflicts of laws thereof. In any action between any of the
parties arising out of or relating to this Option Agreement or any of the
transactions contemplated by this Option Agreement: (a) each of the parties
irrevocably and unconditionally consents and submits to the jurisdiction and
venue of the state and federal courts located in the State of Delaware;
(b) each of the parties irrevocably waives the right to trial by jury; and
(c) each of the parties irrevocably consents to service of process by first
class certified mail, return receipt requested, postage prepaid, to the address
at which such party is to receive notice in accordance with Section 12(b).

        (I)  SEVERABILITY.  If any term, provision, covenant or restriction
contained in this Option Agreement is held by a court of competent jurisdiction
or other authority to be invalid, void, unenforceable or against its regulatory
policy, the remainder of the terms, provisions, covenants and restrictions
contained in this Option Agreement shall remain in full force and effect and
shall in no way be affected, impaired or invalidated.

        (J)  SPECIFIC PERFORMANCE.  The Company agrees that (i) in the event of
any breach or threatened breach by the Company of any covenant, obligation or
other provision set forth in this Option Agreement, the Grantee may be entitled
(in addition to any other remedy that may be available to it) to (A) a decree or
order of specific performance or mandamus to enforce the observance and
performance of such covenant, obligation or other provision, or (B) an
injunction restraining such breach or threatened breach, and (ii) neither the
Grantee nor any other Person shall be required to provide any bond or other
security in connection with any such decree, order or injunction or in
connection with any related action or proceeding.

        (K)  ATTORNEYS' FEES.  In any action at law or suit in equity to enforce
this Option Agreement or the rights of any of the parties hereunder, the
prevailing party in such action or suit shall be entitled to receive a
reasonable sum for its attorneys' fees and all other reasonable costs and
expenses incurred in such action or suit.

        (L)  NON-EXCLUSIVITY.  The rights and remedies of the Company and the
Grantee under this Option Agreement are not exclusive of or limited by any other
rights or remedies which either of them may have, whether at law, in equity, by
contract or otherwise, all of which shall be cumulative (and not alternative).
Without limiting the generality of the foregoing, the rights and remedies of the
Company and the Grantee under this Option Agreement, and the obligations and
liabilities of the Company and the Grantee under this Option Agreement, are in
addition to their respective rights, remedies, obligations and liabilities under
all applicable Legal Requirements and under the Reorganization Agreement. The
covenants and obligations of the Company set forth in this Option Agreement
shall be construed as independent of any other agreement or arrangement between
the Company, on the one hand, and the Grantee, on the other. The existence of
any claim or cause of action by the Company against the Grantee shall not
constitute a defense to the enforcement of any of such covenants or obligations
against the Company.

        (M)  CONSTRUCTION.

           (i) For purposes of this Agreement, whenever the context requires:
       the singular number shall include the plural, and vice versa; the
       masculine gender shall include the feminine and

                                      B-9
<PAGE>
       neuter genders; the feminine gender shall include the masculine and
       neuter genders; and the neuter gender shall include the masculine and
       feminine genders.

           (ii) The parties hereto agree that any rule of construction to the
       effect that ambiguities are to be resolved against the drafting party
       shall not be applied in the construction or interpretation of this
       Agreement.

          (iii) As used in this Agreement, the words "include" and "including"
       and variations thereof, shall not be deemed to be terms of limitation,
       but rather shall be deemed to be followed by the words "without
       limitation."

           (iv) Unless otherwise specified, references in this Agreement to
       "Sections" are intended to refer to Sections of this Agreement.

    IN WITNESS WHEREOF, the Company and the Grantee have caused this Option
Agreement to be executed as of the date first written above.

provision or part thereof under such circumstances and in such jurisdiction
shall not affect the validity or enforceability of such provision or part
thereof under any other circumstances or in any other jurisdiction, and (c) the

this Voting Agreement, and each part of each provision of this Voting Agreement
is separable from every other part of such provision.

    8.5 ENTIRE AGREEMENT.  This Voting Agreement, the Proxy and any other
documents delivered by the parties in connection herewith constitute the entire
agreement between the parties with respect to the subject matter hereof and

    8.7 SPECIFIC PERFORMANCE.  The parties agree that irreparable damage would
occur in the event that any of the provisions of this Voting Agreement or the
Proxy was not performed in accordance with its specific terms or was otherwise
breached. Stockholder agrees that, in the event of any breach or threatened
breach by Stockholder of any covenant or obligation contained in this Voting
Agreement or in the Proxy, Parent shall be entitled (in addition to any other
remedy that may be available to it, including monetary damages) to seek and
obtain (a) a decree or order of specific performance to enforce the observance
and performance of such covenant or obligation, and (b) an injunction
restraining such breach or threatened breach. Stockholder further agrees that
neither Parent nor any other Person shall be required to obtain, furnish or post
any bond or similar instrument in connection with or as a condition to obtaining
any remedy referred to in this Section 8.8, and Stockholder irrevocably waives
any right he may have to require the obtaining, furnishing or posting of any
such bond or similar instrument.

    8.8 NON-EXCLUSIVITY.  The rights and remedies of Parent under this Voting
Agreement are not exclusive of or limited by any other rights or remedies that
it may have, whether at law, in equity, by contract or otherwise, all of which
shall be cumulative (and not alternative). Without limiting the

           (ii) agrees that service of any process, summons, notice or document

       federal court located in the County of San Francisco, California, any
       claim that Stockholder is not subject personally to the jurisdiction of
       such court, that such legal proceeding has been brought in an
       inconvenient forum, that the venue of such proceeding is improper or that
       this Voting Agreement or the subject matter of this Voting Agreement may
       not be enforced in or by such court.

power, right, privilege or remedy under this Voting Agreement, and no delay on
the part of Parent in exercising any power, right, privilege or remedy under
this Voting Agreement, shall operate as a waiver of such power, right, privilege
or remedy; and no single or partial exercise of any such power, right, privilege
or remedy shall preclude any other or further exercise thereof or of any other
power, right, privilege or remedy. Parent shall not be deemed to have waived any
claim available to Parent arising out of this Voting Agreement, or any power,
right, privilege or remedy of Parent under this Voting Agreement, unless the
waiver of such claim, power, right, privilege or remedy is expressly set forth
in a written instrument duly executed and delivered on behalf of Parent; and any
such waiver shall not be applicable or have any effect except in the specific
instance in which it is given. If the Reorganization Agreement is terminated,

                           FORM OF IRREVOCABLE PROXY

    The undersigned stockholder of INTERLEAF, INC., a Massachusetts corporation
(the "Company"), hereby irrevocably (to the fullest extent permitted by law)
appoints and constitutes Randall Bolten, Scott Neely and BROADVISION, INC., a
Delaware corporation ("Parent"), and each of them, the attorneys and proxies of
the undersigned with full power of substitution and resubstitution, to the full
extent of the undersigned's rights with respect to (i) the outstanding shares of
capital stock of the Company owned of record by the undersigned as of the date
of this proxy, which shares are specified on the final page of this proxy, and
(ii) any and all other shares of capital stock of the Company which the
undersigned may acquire on or after the date hereof. (The shares of the capital
stock of the Company referred to in clauses "(i)" and "(ii)" of the immediately
preceding sentence are collectively referred to as the "Shares.") Upon the
execution hereof, all prior proxies given by the undersigned with respect to any
of the Shares are hereby revoked, and the undersigned agrees that no subsequent
proxies will be given with respect to any of the Shares.

    This proxy is irrevocable, is coupled with an interest and is granted in
connection with the Voting Agreement, dated as of the date hereof, between
Parent and the undersigned (the "Voting Agreement"), and is granted in
consideration of Parent entering into the Agreement and Plan of Merger and
Reorganization, dated as of the date hereof, among Parent, Infiniti Acquisition
Sub, Inc. and the Company (the "Reorganization Agreement"). This proxy shall be
automatically terminated as to any Subject Securities that are sold by the
undersigned pursuant to Section 2.1(b) of the Voting Agreement.

    The attorneys and proxies named above will be empowered, and may exercise
this proxy, to vote the Shares at any time until the earlier to occur of the
valid termination of the Reorganization Agreement or the effective time of the
merger contemplated thereby (the "Merger") at any meeting of the stockholders of
the Company, however called, or in connection with any solicitation of written
consents from stockholders of the Company, in favor of the approval and adoption
of the Reorganization Agreement and the approval of the Merger, and in favor of
each of the other actions contemplated by the Reorganization Agreement.

    The undersigned may vote the Shares on all other matters.

    This proxy shall be binding upon the heirs, estate, executors, personal
representatives, successors and assigns of the undersigned (including any
transferee of any of the Shares).

    If any provision of this proxy or any part of any such provision is held
under any circumstances to be invalid or unenforceable in any jurisdiction, then
(a) such provision or part thereof shall, with respect to such circumstances and
in such jurisdiction, be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible extent, (b) the invalidity or
unenforceability of such provision or part thereof under such circumstances and
in such jurisdiction shall not affect the validity or enforceability of such
provision or part thereof under any other circumstances or in any other
jurisdiction, and (c) the invalidity or unenforceability of such provision or
part thereof shall not affect the validity or enforceability of the remainder of
such provision or the validity or enforceability of any other provision of this
proxy. Each provision of this proxy is separable from every other provision of
this proxy, and each part of each provision of this proxy is separable from

                      BROADVIEW INTERNATIONAL LLC OPINION

                                                                January 26, 2000
                                                                    CONFIDENTIAL

Board of Directors
Interleaf, Inc.
62 Fourth Avenue
Waltham, MA 02154

Dear Members of the Board:

    We understand that Interleaf, Inc. ("Interleaf" or "Company"),
BroadVision, Inc. ("BroadVision" or "Parent") and Infiniti Acquisition
Sub, Inc., a wholly-owned subsidiary of Parent ("Merger Sub"), propose to enter
into an Agreement and Plan of Merger and Reorganization (the "Agreement")
pursuant to which, through the merger of Merger Sub with and into the Company
(the "Merger"), each outstanding share of common stock of the Company ("Company
Common Stock") will be converted into the right to receive 0.3465 (the "Exchange
Ratio") shares of common stock of the parent ("Parent Common Stock"). The Merger
is intended to qualify as a reorganization within the meaning of Section 368(a)
of the United States Internal Revenue Code of 1986, as amended. The terms and
conditions of the above described Merger are more fully detailed in the
Agreement.

    You have requested our opinion as to whether the Exchange Ratio is fair,
from a financial point of view, to Interleaf stockholders.

    Broadview International LLC ("Broadview") focuses on providing merger and
acquisition advisory services to information technology ("IT"), communications
and media companies. In this capacity, we are continually engaged in valuing
such businesses, and we maintain an extensive database of IT, communications and
media mergers and acquisitions for comparative purposes. We are currently acting
as financial advisor to Interleaf's Board of Directors and will receive a fee
from Interleaf upon the successful conclusion of the Merger.

    In rendering our opinion, we have, among other things:

 1.) reviewed the terms of a draft of the Agreement dated January 26, 2000
     furnished to us by the Company on January 26, 2000 (which, for the purposes
     of this opinion, we have assumed, with your permission, to be identical in
     all material respects to the Agreement to be executed, except that we have
     assumed with your permission that the Exchange Ratio is 0.3465);

 2.) reviewed Interleaf's annual report on Form 10-K for the fiscal year ended
     March 31, 1999, including the audited financial statements included
     therein, and Interleaf's quarterly report on Form 10-Q for the period ended
     September 30, 1999, including the unaudited financial statements included
     therein;

 3.) reviewed Interleaf's draft registration statement on Form S-3;

 4.) reviewed certain internal financial and operating information concerning
     Interleaf, including preliminary financial results for the three months
     ending December 31, 1999 and quarterly projections through March 31, 2002,
     relating to Interleaf, prepared and furnished to us by Interleaf
     management;

 5.) participated in discussions with Interleaf management concerning the
     operations, business strategy, current financial performance and prospects
     for Interleaf;

                                      D-1
<PAGE>
 6.) discussed with Interleaf management its view of the strategic rationale for
     the Merger;

 7.) reviewed the recent reported closing prices and trading activity for
     Company Common Stock;

 8.) compared certain aspects of the financial performance of Interleaf with
     public companies we deemed comparable;

 9.) analyzed available information, both public and private, concerning other
     mergers and acquisitions we believe to be comparable in whole or in part to
     the Merger;

 10.) reviewed recent equity research analyst reports covering Interleaf;

 11.) reviewed BroadVision's annual report on Form 10-K for the fiscal year
      ended December 31, 1998, including the audited financial statements
      included therein, and BroadVision's quarterly report on Form 10-Q for the
      period ended September 30, 1999, including the unaudited financial
      statements included therein;

 12.) reviewed BroadVision's prospectus on Form 424(B)(4);

 13.) participated in discussions with BroadVision management concerning the
      operations, business strategy, financial performance and prospects for
      BroadVision;

 14.) reviewed the recent reported closing prices and trading activity for
      BroadVision Common Stock;

 15.) discussed with BroadVision management its view of the strategic rationale
      for the Merger;

 16.) compared certain aspects of the financial performance of BroadVision with
      public companies we deemed comparable;

 17.) reviewed recent equity analyst reports covering BroadVision;

 18.) analyzed the anticipated effect of the Merger on the future financial
      performance of the combined entity;

 19.) participated in discussions related to the Merger with Interleaf,
      BroadVision and their respective advisors; and

 20.) conducted other financial studies, analyses and investigations as we
      deemed appropriate for purposes of this opinion.

    In rendering our opinion, we have relied, without independent verification,
on the accuracy and completeness of all the financial and other information
(including without limitation the representations and warranties contained in
the Agreement) that was publicly available or furnished to us by Interleaf or
BroadVision. With respect to the financial projections examined by us, we have
assumed that they were reasonably prepared and reflected the best available
estimates and good faith judgments of the management of Interleaf as to the
future performance of Interleaf. We have neither made nor obtained an
independent appraisal or valuation of any of Interleaf's assets.

    Based upon and subject to the foregoing, we are of the opinion that the
Exchange Ratio is fair, from a financial point of view, to Interleaf
stockholders.

    For purposes of this opinion, we have assumed that neither Interleaf nor
BroadVision is currently involved in any material transaction other than the
Merger, other publicly announced transactions, other preliminary discussions
confidentially disclosed to us, and those activities undertaken in the ordinary
course of conducting their respective businesses. Our opinion is necessarily
based upon market, economic, financial and other conditions as they exist and
can be evaluated as of the date of this opinion, and any change in such
conditions would require a reevaluation of this opinion. We express no opinion
as to the price at which BroadVision Common Stock will trade at any time in the
future.

    This opinion speaks only as of the date hereof. It is understood that this
opinion is for the information of the Board of Directors of Interleaf in
connection with its consideration of the Merger and does not constitute a
recommendation to any Interleaf stockholder as to how such stockholder should
vote on the Merger. This opinion may not be published or referred to, in whole
or part, without our prior written permission, which shall not be unreasonably
withheld. Broadview hereby consents to references to and the inclusion of this
opinion in its entirety in the Prospectus/Proxy Statement to be distributed to
Interleaf stockholders in connection with the Merger.

                                               Sincerely,
                                               Broadview International LLC

                                                                         ANNEX E

                             SECTIONS 85 THROUGH 98
                                   INCLUSIVE
                 OF THE MASSACHUSETTS BUSINESS CORPORATION LAW
                              (DISSENTERS' RIGHTS)

SECTION 85. DISSENTING STOCKHOLDER; RIGHT TO DEMAND PAYMENT FOR STOCK;
EXCEPTION.  A stockholder in any corporation organized under the laws of
Massachusetts which shall have duly voted to consolidate or merge with another
corporation or corporations under the provisions of sections seventy-eight or
seventy-nine who objects to such consolidation or merger may demand payment for
his stock from the resulting or surviving corporation and an appraisal in
accordance with the provisions of sections eighty-six to ninety-eight,
inclusive, and such stockholder and the resulting or surviving corporation shall
have the rights and duties and follow the procedure set forth in those sections.
This section shall not apply to the holders of any shares of stock of a
constituent corporation surviving a merger if, as permitted by subsection
(c) of section seventy-eight, the merger did not require for its approval a vote
of the stockholders of the surviving corporation.

SECTION 86. SELECTIONS APPLICABLE TO APPRAISAL; PREREQUISITES.  If a corporation
proposes to take a corporate action as to which any section of this chapter
provides that a stockholder who objects to such action shall have the right to
demand payment for his shares and an appraisal thereof, 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.

SECTION 87. STATEMENT OF RIGHTS OF OBJECTING STOCKHOLDERS IN NOTICE OF 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. The notice may be in such form as the directors
or officers calling the meeting deem advisable, but the following form of notice
shall be sufficient to comply with this section:

    "If the action proposed is approved by the stockholders at the meeting and
    effected by the corporation, any stockholder (1) who files with the
    corporation before the taking of the vote on the approval of such action,
    written objection to the proposed action stating that he intends to demand
    payment for his shares if the action is taken and (2) whose shares are not
    voted in favor of such action has or may have the right to demand in writing
    from the corporation (or, in the case of a consolidation or merger, the name
    of the resulting or surviving corporation shall be inserted), within twenty
    days after the date of mailing to him of notice in writing that the
    corporate action has become effective, payment for his shares and an
    appraisal of the value thereof. Such corporation and any such stockholder
    shall in such cases have the rights and duties and shall follow the
    procedure set forth in sections 88 to 98, inclusive, of chapter 156B of the
    General Laws of Massachusetts."

SECTION 88. NOTICE OF EFFECTIVENESS OF ACTION OBJECTED TO BY STOCKHOLDER.  The
corporation taking such action, or in the case of a merger or consolidation the
surviving or resulting corporation, shall, within ten days after the date on
which such corporate action became effective, notify each stockholder who

                                      E-1
<PAGE>
filed a written objection meeting the requirements of section eighty-six and
whose shares were not voted in favor of the approval of such action, that the
action approved at the meeting of the corporation of which he is a stockholder
has become effective. 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. The notice shall be sent by registered or certified mail, addressed to
the stockholder at his last known address as it appears in the records of the
corporation.

SECTION 89. DEMAND FOR PAYMENT; TIME FOR PAYMENT.  If within twenty days after
the date of mailing of a notice under subsection (e) of section eighty-two,
subsection (f) of section eighty-three, or section eighty-eight, any stockholder
to whom the corporation was required to give such notice shall demand in writing
from the corporation taking such action, or in the case of a consolidation or
merger from the resulting or surviving corporation, payment for his stock, the
corporation upon which such demand is made shall pay to him the fair value of
his stock within thirty days after the expiration of the period during which
such demand may be made.

SECTION 90. DEMAND FOR DETERMINATION OF VALUE; BILL IN EQUITY; VENUE.  If during
the period of thirty days provided for in section eighty-nine the corporation
upon which such demand is made and any such objecting stockholder fail to agree
as to the value of such stock, such corporation or any such stockholder may
within four months after the expiration of such thirty-day period demand a
determination of the value of the stock of all such objecting stockholders by a
bill in equity filed in the superior court in the county where the corporation
in which such objecting stockholder held stock had or has its principal office
in the commonwealth.

SECTION 91. PARTIES TO SUIT TO DETERMINE VALUE; SERVICE.  If the bill is filed
by the corporation, it shall name as parties respondent all stockholders who
have demanded payment for their shares and with whom the corporation has not
reached agreement as to the value thereof. If the bill is filed by a
stockholder, he shall bring the bill in his own behalf and in 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.

SECTION 92. DECREE DETERMINING VALUE AND ORDERING PAYMENT; VALUATION
DATE.  After hearing the court shall enter a decree determining the fair value
of the stock of those stockholders who have become entitled to the valuation of
and 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 representing such stock if certificated or, if uncertificated,
upon receipt of an instruction transferring such stock to the corporation. For
this purpose, the value of the shares shall be determined as of the day
preceding the date of the vote approving the proposed corporate action and shall
be exclusive of any element of value arising from the expectation or
accomplishment of the proposed corporate action.

                                      E-2
<PAGE>
SECTION 93. REFERENCE TO SPECIAL MASTER.  The court in its discretion may refer
the bill or any question arising 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.

SECTION 94. NOTATION ON STOCK CERTIFICATES OF PENDENCY OF BILL.  On motion the
court may order stockholder parties to the bill to submit their certificates of
stock to the corporation for the notation thereon of the pendency of the bill
and may order the corporation to note such pendency in its records with respect
to any uncertificated shares held by such stockholder parties, and may on motion
dismiss the bill as to any stockholder who fails to comply with such order.

SECTION 95. COSTS; INTEREST.  The costs of the bill, including the reasonable
compensation and expenses 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 the parties to the bill, or any of them, in such manner as
appears to be equitable, except that all costs of giving notice to stockholders
as provided in this chapter shall be paid by the corporation. Interest shall be
paid upon any award from the date of the vote approving the proposed corporate
action, and the court may on application of any interested party determine the
amount of interest to be paid in the case of any stockholder.

SECTION 96. DIVIDENDS AND VOTING RIGHTS AFTER DEMAND FOR PAYMENT.  Any
stockholder who has demanded payment for his stock as provided in this chapter
shall not thereafter be entitled to notice of any meeting of stockholders or to
vote such stock for any purpose and shall not be entitled to the payment of
dividends or other distribution on the stock (except dividends or other
distributions payable to stockholders of record at a date which is prior to the
date of the vote approving the proposed corporate action) unless:

    (1) A bill shall not be filed within the time provided in section ninety;

    (2) A bill, if filed, shall be dismissed as to such stockholder; or

    (3) Such stockholder shall with the written approval of the corporation, or
       in the case of a consolidation or merger, the resulting or surviving
       corporation, deliver to it a written withdrawal of his objections to and
       an acceptance of such corporate action.

    Notwithstanding the provisions of clauses (1) to (3), inclusive, said
stockholder shall have only the rights of a stockholder who did not so demand
payment for his stock as provided in this chapter.

SECTION 97. STATUS OF SHARES PAID FOR.  The shares of the corporation paid for
by the corporation pursuant to the provisions of this chapter shall have the
status of treasury stock, or in the case of a consolidation or merger the shares
or the securities of the resulting or surviving corporation into which the
shares of such objecting stockholder would have been converted had he not
objected to such consolidation or merger shall have the status of treasury stock
or securities.

SECTION 98. EXCLUSIVE REMEDY; EXCEPTION.  The enforcement by a stockholder of
his right to receive payment for his shares in the manner provided in this
chapter shall be an exclusive remedy except that this chapter shall not exclude
the right of such stockholder to bring or maintain an appropriate proceeding to
obtain relief on the ground that such corporate action will be or is illegal or
fraudulent as to him.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145 of the Delaware General Corporation Law, Article Sixth of
BroadVision's Restated Certificate of Incorporation, Article XI of BroadVision's
bylaws, as amended, and indemnification agreements entered into by BroadVision
with its directors provide for the exculpation of directors and the
indemnification of officers, directors, employees and agents under certain
circumstances.

    Set forth below is Article Sixth of BroadVision's Restated Certificate of
Incorporation pertaining to indemnification of officers, directors, employees
and agents and insurance:

       VI. A. A director of the corporation shall not be personally liable to
       the corporation or its stockholders for monetary damages for any breach
       of fiduciary duty as a director, except for liability (i) for any breach
       of the director's duty of loyalty to the corporation or its stockholders,
       (ii) for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law (iii) under Section 174 of the
       Delaware General Corporation Law, or (iv) for any transaction from which
       the director derived an improper personal benefit. If the Delaware
       General Corporation Law is amended after approval by the stockholders of
       this Article to authorize corporate action further eliminating or
       limiting the personal liability of directors, then the liability of a
       director shall be eliminated or limited to the fullest extent permitted
       by the Delaware General Corporation Law, as so amended.

Set forth below is Article XI of BroadVision's bylaws, as amended:

       "ARTICLE XI INDEMNIFICATION. Section 43. Indemnification of Directors,
       Executive Officers, Other Officers, Employees and Other Agents.
       (a) Directors. The corporation shall indemnify its directors to the
       fullest extent not prohibited by the Delaware General Corporation Law;
       provided, however, that the corporation may modify the extent of such
       indemnification by individual contracts with its directors; and,
       provided, further, that the corporation shall not be required to
       indemnify any director in connection with any proceeding (or part
       thereof) initiated by such person unless (i) such indemnification is
       expressly required to be made by law, (ii) the proceeding was authorized
       by the Board of Directors of the corporation, (iii) such indemnification
       is provided by the corporation, in its sole discretion, pursuant to the
       powers vested in the corporation under the Delaware General Corporation
       Law or (iv) such indemnification is required to be made under subsection
       (d).

       (b)  Other Officers, Employees and Other Agents. The corporation shall
       have power to indemnify its other officers, employees and other agents as
       set forth in the Delaware General Corporation Law.

       (c)  Expenses. The corporation shall advance to any person who was or is
       a party or is threatened to be made a party to any threatened, pending or
       completed action, suit or proceeding, whether civil, criminal,
       administrative or investigative, by reason of the fact that he is or was
       a director of the corporation, or is or was serving at the request of the
       corporation as a director or executive officer of another corporation,
       partnership, joint venture, trust or other enterprise, prior to the final
       disposition of any proceeding, promptly following request therefor, all
       expenses incurred by any director in connection with such proceeding upon
       receipt of an undertaking by or on behalf of such person to repay said
       amounts if it should be determined ultimately that such person is not
       entitled to be indemnified under this Bylaw or otherwise.

       Notwithstanding the foregoing, unless otherwise determined pursuant to
       paragraph (e) of this Bylaw, no advance shall be made by the corporation
       to an officer of the corporation (except

                                      II-1
<PAGE>
       by reason of the fact that such officer is or was a director of the
       corporation in which event this paragraph shall not apply) in any action,
       suit or proceeding, whether civil, criminal, administrative or
       investigative if a determination is reasonably and promptly made (i) by
       the Board of Directors by a majority vote of a quorum consisting of
       directors who were not parties to the proceeding, or (ii) if such quorum
       is not obtainable, or, even if obtainable, a quorum of disinterested
       directors so directs, by independent legal counsel in a written opinion,
       that the facts known to the decision-making party at the time such
       determination is made demonstrate clearly and convincingly that such
       person acted in bad faith or in a manner that such person did not believe
       to be in or not opposed to the best interests of the corporation.

       (d)  Enforcement. Without the necessity of entering into an express
       contract, all rights to indemnification and advances to directors under
       this Bylaw shall be deemed to be contractual rights and be effective to
       the same extent and as if provided for in a contract between the
       corporation and the director. Any right to indemnification or advances
       granted by this Bylaw to a director shall be enforceable by or on behalf
       of the person holding such right in any court of competent jurisdiction
       if (i) the claim for indemnification or advances is denied, in whole or
       in part, or (ii) no disposition of such claim is made within ninety
       (90) days of request therefor. The claimant in such enforcement action,
       if successful in whole or in part, shall be entitled to be paid also the
       expense of prosecuting his claim. In connection with any claim for
       indemnification, the corporation shall be entitled to raise as a defense
       to any such action that the claimant has not met the standards of conduct
       that make it permissible under the Delaware General Corporation Law for
       the corporation to indemnify the claimant for the amount claimed. Neither
       the failure of the corporation (including its Board of Directors,
       independent legal counsel or its stockholders) to have made a
       determination prior to the commencement of such action that
       indemnification of the claimant is proper in the circumstances because he
       has met the applicable standard of conduct set forth in the Delaware
       General Corporation Law, nor an actual determination by the corporation
       (including its Board of Directors, independent legal counsel or its
       stockholders) that the claimant has not met such applicable standard of
       conduct, shall be a defense to the action or create a presumption that
       claimant has not met the applicable standard of conduct.

       (e)  Non-Exclusivity of Rights. The rights conferred on any person by
       this Bylaw shall not be exclusive of any other right which such person
       may have or hereafter acquire under any statute, provision of the
       Certificate of Incorporation, Bylaws, agreement, vote of stockholders or
       disinterested directors or otherwise, both as to action in his official
       capacity and as to action in another capacity while holding office. The
       corporation is specifically authorized to enter into individual contracts
       with any or all of its directors, officers, employees or agents
       respecting indemnification and advances, to the fullest extent not
       prohibited by the Delaware General Corporation Law.

       (f)  Survival of Rights. The rights conferred on any person by this Bylaw
       shall continue as to a person who has ceased to be a director, officer,
       employee or other agent and shall inure to the benefit of the heirs,
       executors and administrators of such a person.

       (g)  Insurance. To the fullest extent permitted by the Delaware General
       Corporation Law, the corporation, upon approval by the Board of
       Directors, may purchase insurance on behalf of any person required or
       permitted to be indemnified pursuant to this Bylaw.

       (h)  Amendments. Any repeal or modification of this Bylaw shall only be
       prospective and shall not affect the rights under this Bylaw in effect at
       the time of the alleged occurrence of any action or omission to act that
       is the cause of any proceeding against any agent of the corporation.

                                      II-2
<PAGE>
       (i)  Saving Clause. If this Bylaw or any portion hereof shall be
       invalidated on any ground by any court of competent jurisdiction, then
       the corporation shall nevertheless indemnify each Director and executive
       officer to the full extent not prohibited by any applicable portion of
       this Bylaw that shall not have been invalidated, or by any other
       applicable law.

       (j)  Certain Definitions. For the purposes of this Bylaw, the following
       definitions shall apply:

           (i)  The term "proceeding" shall be broadly construed and shall
               include, without limitation, the investigation, preparation,
               prosecution, defense, settlement, arbitration and appeal of, and
               the giving of testimony in, any threatened, pending or completed
               action, suit or proceeding, whether civil, criminal,
               administrative or investigative.

           (ii) The term "expenses" shall be broadly construed and shall
               include, without limitation, court costs, attorneys' fees,
               witness fees, fines, amounts paid in settlement or judgment and
               any other costs and expenses of any nature or kind incurred in
               connection with any proceeding.

           (iii) The term the "corporation" shall include, in addition to the
               resulting corporation, any constituent corporation (including any
               constituent of a constituent) absorbed in a consolidation or
               merger which, if its separate existence had continued, would have
               had power and authority to indemnify its directors, officers, and
               employees or agents, so that any person who is or was a director,
               officer, employee or agent of such constituent corporation, or is
               or was serving at the request of such constituent corporation as
               a director, officer, employee or agent of another corporation,
               partnership, joint venture, trust or other enterprise, shall
               stand in the same position under the provisions of this Bylaw
               with respect to the resulting or surviving corporation as he
               would have with respect to such constituent corporation if its
               separate existence had continued.

           (iv) References to a "director," "officer," "employee," or "agent" of
               the corporation shall include, without limitation, situations
               where such person is serving at the request of the corporation as
               a director, officer, employee, trustee or agent of another
               corporation, partnership, joint venture, trust or other
               enterprise.

           (v) References to "other enterprises" shall include employee benefit
               plans; references to "fines" shall include any excise taxes
               assessed on a person with respect to an employee benefit plan;
               and references to "serving at the request of the corporation"
               shall include any service as a director, officer, employee or
               agent of the corporation which imposes duties on, or involves
               services by, such director, officer, employee, or agent with
               respect to an employee benefit plan, its participants, or
               beneficiaries; and a person who acted in good faith and in a
               manner he reasonably believed to be in the interest of the
               participants and beneficiaries of an employee benefit plan shall
               be deemed to have acted in a manner "not opposed to the best
               interests of the corporation" as referred to in this Bylaw."

    In addition, BroadVision has entered into indemnification agreements with
its directors and officers pursuant to which BroadVision has agreed to indemnify
such directors and officers in accordance with, and to the fullest extent
permitted by, the Delaware General Corporation Law, against any and all
expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by the indemnitee in connection with any proceeding in which
the indemnitee was or is made a party or was or is involved by reason of the
fact that the indemnitee is or was a director or an officer.

    BroadVision has also purchased liability insurance policies covering certain
directors and officers of BroadVision.

ITEM 22. UNDERTAKINGS.

    The undersigned Registrant hereby undertakes:

    (1)  To file, during any period in which offers or sales are being made, a
    post-effective amendment to this registration statement:

        (i) To include any prospectus required in Section 10(a) (3) of the
            Securities Act of 1933;

                                      II-4
<PAGE>
        (ii) To reflect in the prospectus any facts or events arising after the
             effective date of the registration statement (or the most recent
             post-effective amendment thereof) which, individually or in the
             aggregate, represent a fundamental change in the information set
             forth in the registration statement;

       (iii) To include any material information with respect to the plan of
             distribution not previously disclosed in the registration statement
             or any material change to such information in the registration
             statement;

    provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
    information required to be included in a post-effective amendment by those
    paragraphs is contained in periodic reports filed by the Registrant pursuant
    to section 13 or section 15(d) of the Securities Exchange Act of 1934 that
    are incorporated by reference in the registration statement;

    (2)  That, for the purpose 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)  To remove from registration by means of a post-effective amendment any
    of the securities being registered which remain unsold at the termination of
    the offering;

    (4)  That, for purposes of determining any liability under the Securities
    Act of 1933, each filing of the registrant's annual report pursuant to
    section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
    where appropriate, each filing of an employee benefit plan's annual report
    pursuant to section 15(d) of the Securities Exchange Act of 1934) that is
    incorporated by reference in the registration statement shall be deemed to
    be a new registration statement relating to the securities offered therein,
    and the offering of such securities at that time shall be deemed to be the
    initial bona tide offering thereof;

    (5)  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;

    (6)  That, prior to any public reoffering of the securities registered
    hereunder through use of a prospectus which is a part of this registration
    statement, by any person or party who is deemed to be an underwriter within
    the meaning of Rule 145(c), the issuer undertakes that such reoffering
    prospectus will contain the information called for by the applicable
    registration form with respect to reofferings by persons who may be deemed
    underwriters, in addition to the information called for by the other items
    of the applicable form;

    (7)  That every prospectus (i) that is filed pursuant to
    paragraph (6) immediately preceding, or (ii) that purports to meet the
    requirements of Section 10(a)(3) of the Securities Act and is used in
    connection with an offering of securities subject to Rule 415, will be filed
    as a part of an amendment to the registration statement and will not be used
    until such amendment is effective, and that, for purposes of determining any
    liability under the Securities Act, each such post-effective amendment shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof; and

    (8)  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.

                                      II-5
<PAGE>
    (9)  Insofar as 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 provisions described under Item 20 above,
    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 Securities 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 Securities Act and will be
    governed by the final adjudication of such issue.

Ladies and Gentlemen:

We have acted as counsel for BroadVision, Inc. (the "Company" or "BroadVision"),
in connection with the merger (the "Merger") and other transactions contemplated
by that certain Agreement and Plan of Merger and Reorganization, dated as of
January 26, 2000, by and among BroadVision, Infiniti Acquisition Sub, Inc., a
Massachusetts corporation and a wholly-owned subsidiary of BroadVision ("Merger
Sub"), and Interleaf, Inc., a Massachusetts corporation ("Interleaf"). This
opinion is being furnished in connection with a Registration Statement on Form
S-4 (the "Registration Statement") with the Securities and Exchange Commission
(the "Commission") covering the offer and sale of up to 14,108,498 shares of
common stock (the "Shares"), to be issued in connection with the merger of
Merger Sub with and into Interleaf.

In rendering this opinion, we have examined the following documents (i) the
Company's Certificate of Incorporation and Bylaws, as amended and restated since
the inception of the Company; (ii) the minutes of the Board of Directors'
meeting convened on January 25, 2000; (iii) the Registration Statement; and (iv)
such other documents, legal opinions, precedents, corporate and other records of
the Company, and certificates of public officials and officers of the Company
that we have deemed necessary or appropriate to provide the basis for the below
opinion.

We are of the opinion that the Shares, which are being offered and sold by the
Company pursuant to the Registration Statement, when sold in the manner and for
the consideration contemplated by the Registration Statement, will be validly
issued, fully paid and non-assessable.

We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to our firm under the heading "Legal Matters."

Very truly yours,
