(1) Associated with the Common Stock are preferred stock purchase rights that
    will not be exercisable or be evidenced separately from the Common Stock
    prior to the occurrence of certain events.
 
(2) The number of shares of Common Stock and Series B Preferred Stock of the
    Registrant to be registered is based on the number of outstanding shares of
    the Registrant that the Registrant estimates will be issued and outstanding
    as of the closing date of the merger to which this Registration Statement
    relates. The number of shares of Common Stock to be registered also includes
    shares of Common Stock issuable upon conversion of the shares of Series B
    Preferred Stock of the Registrant and upon the exercise of the Warrants to
    purchase Common Stock (the "Warrants") to be issued in the merger. This
    Registration Statement also covers such indeterminate number of shares, if
    any, as shall be issuable from time to time as required pursuant to
    adjustments pursuant to the terms of the Series B Preferred Stock and the
    Warrants.
 
(3) Pursuant to Rule 457(f) under the Securities Act of 1933, the registration
    fee was computed on the basis of (i) the market value of the outstanding
    shares of the Registrant to be exchanged in the merger, computed in
    accordance with Rule 457(g) on the basis of the average of the high and low
    prices per share of such stock on January 11, 1999, as reported by The
    Nasdaq Stock Market, less the product of 5,097,000 and $2.06, representing
    cash to be paid by Xerox Corporation for shares of the Registrant in the
    merger, plus (ii) in accordance with Rule 457(f)(2), the book value of the
    securities of ScanSoft, Inc. to be received in the merger, which was
    $3,288,000 as of September 30, 1998, the most recent practicable date.
 
(4) A filing fee of $658 was previously paid by the Registrant pursuant to Rule
    14a-6 under the Securities Exchange Act of 1934 in connection with the
    filing of the preliminary proxy statement/prospectus on December 24, 1998.
    Pursuant to Rule 457(b) under the Securities Act of 1933, such fee is being
    credited against the registration fee and, accordingly, $4,236 is being paid
    in connection with the Registration Statement.
 
    THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF
THE SECURITIES ACT OF 1933 OR UNTIL THE REGISTRATION STATEMENT SHALL BECOME
EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(a),
MAY DETERMINE.

                                       OF
                                VISIONEER, INC.
 
To the Stockholders of Visioneer, Inc.:
 
     The board of directors of Visioneer, Inc. has approved the merger of
ScanSoft, Inc., an indirect wholly owned subsidiary of Xerox Corporation, and
Visioneer. Visioneer will be the Surviving Corporation. In the proposed merger,
you can choose to receive, for each of your shares, $2.06 in cash or one share
of Surviving Corporation common stock. The Surviving Corporation common stock
will be the same as your current shares, except that the name of the Surviving
Corporation will be changed to ScanSoft, Inc. The amount of cash that you may
receive in the merger will be subject to certain limitations and adjustments, as
described in this document. At least 5,097,000 shares of Visioneer common stock
will be exchanged for cash in the merger.
 
     Xerox Imaging Systems, Inc., a subsidiary of Xerox, is currently the sole
stockholder of ScanSoft. If the merger is completed, Xerox Imaging Systems will
own 45% of the outstanding common stock and all of the convertible Series B
preferred stock of the Surviving Corporation. The Series B preferred stock is
non-voting and will be convertible into Surviving Corporation common stock in
certain circumstances. All outstanding options to purchase ScanSoft stock will
become options to purchase Surviving Corporation common stock. Xerox will
receive a common stock warrant exercisable for that number of shares equal to
the number of assumed ScanSoft option shares that are forfeited from time to
time after the merger. On a fully-diluted basis, Xerox and the former ScanSoft
optionholders will own approximately 53.8% of the Surviving Corporation's
capital stock after the merger, subject to adjustment.
 
     The merger cannot be completed unless the holders of a majority of the
outstanding shares of Visioneer common stock on the record date vote to approve
the merger agreement and the merger, including an amendment to Visioneer's
certificate of incorporation. Visioneer's board of directors has called a
special meeting of stockholders to vote on the merger agreement and the merger
on:
 
                  February 23, 1999 at 10:00 a.m., local time
             at the principal executive offices of Visioneer, Inc.

                           Fremont, California 94555
 
     Whether or not you plan to attend the special meeting, please complete,

stockholders who held their shares of Visioneer common stock at the close of
business on January 12, 1999 will be entitled to vote on the merger agreement

to whom it would be unlawful to make an offer or solicitation. You should not
assume that the information contained in this proxy statement/prospectus is

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
Q: WHY IS VISIONEER PROPOSING THE MERGER? HOW WILL I BENEFIT?
 
A: We believe that the proposed merger will create a company well positioned to
   build upon Visioneer and ScanSoft's heritage of leadership in the digital
   imaging software market. We believe the combined company will have an
   effective cost structure, a strong development team and well-branded
   products, which we believe can create value for stockholders.
 
    To review the background and reasons for the merger in greater detail, see
pages 28-32.
 
Q: WHEN IS THE SPECIAL MEETING?
 
A: The special meeting will take place on February 23, 1999. At the special
   meeting, Visioneer stockholders will be asked to approve the merger and the
   related merger agreement signed by Visioneer and ScanSoft on December 2,
   1998. As part of the merger, Visioneer will also amend its certificate of
   incorporation. Xerox Imaging Systems, Inc., a subsidiary of Xerox Corporation
   and ScanSoft's sole stockholder, has already approved the merger agreement
   and the merger.
 
    For additional information regarding the special meeting, see page 25.
 
Q: WHAT DO I NEED TO DO NOW?
 
A: Please mail your signed proxy card in the enclosed return envelope as soon as
   possible, so that your shares may be represented at the special meeting. We
   prefer that you sign and return your completed proxy card whether or not you
   attend the special meeting in person. You must also fill out the enclosed
   cash election form to indicate whether you want to receive cash for your
   shares or if you want your shares to be converted into shares of Surviving
   Corporation common stock. You must send the following to U.S. Stock Transfer
   Corporation, Visioneer's exchange agent, at the address shown on the cash
   election form:
 
        - a completed cash election form and
 
        - all of your stock certificates, endorsed according to the instructions
          on the cash election form.
 
   If you do not return the cash election form and your endorsed stock
   certificates in the enclosed envelope to U.S. Stock Transfer Corporation by
   5:00 p.m. New York time (2:00 p.m. California time) on the date of the
   special meeting, your shares will be treated in the same manner as the shares
   that elect to be converted into shares of Surviving Corporation common stock,
   subject to the proration discussed below.
 
Q: WHAT IS THE DIFFERENCE BETWEEN SHARES OF SURVIVING CORPORATION COMMON STOCK
   AND VISIONEER COMMON STOCK?
 
A: They are the same. Visioneer will be the Surviving Corporation, although its
   name will be changed to "ScanSoft, Inc." Therefore, you should return any
   stock certificates with the "Visioneer, Inc." name so they can be replaced
   with new stock certificates with the name "ScanSoft, Inc."
 
Q: WHAT DO I DO IF I WANT TO CHANGE MY VOTE?
 
A: Just complete, date and sign a new proxy card and mail it to Visioneer. The
   new proxy card must arrive before the date of the special meeting. You can
   also attend the meeting in person and vote.
 
Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
   SHARES FOR ME?
 
A: Your broker will vote your shares only if you provide instructions on how to
   vote. You should instruct your broker to vote your shares, following the
   directions provided by your broker. Without instructions, your shares will
   not be voted. Shares which are not voted will have the same effect as votes
   against the merger.
 
Q: PLEASE EXPLAIN WHAT I WILL RECEIVE IN THE MERGER.
 
A: If the merger is completed, and subject to certain proration and book value
   adjustments discussed below, Visioneer stockholders who chose to convert
   their shares into cash will receive $2.06 per share. At least 5,097,000
   shares of Visioneer common stock will be exchanged for cash. Visioneer
   stockholders who chose
 
                                        3
<PAGE>   10
 
   not to receive cash but to receive shares of Surviving Corporation common
   stock will receive new stock certificates for shares of Surviving Corporation
   common stock.
 
    However, if holders of more than 5,097,000 shares of Visioneer common stock
    choose to receive cash, there will be a proration or pro rata cutback. Under
    this cutback, stockholders who elected to receive cash will only receive
    cash for a portion of their shares. Conversely, if holders of less than
    5,097,000 shares chose to receive cash, there will be a pro rata increase
    such that stockholders who elected to receive Surviving Corporation common
    stock will only be able to receive Surviving Corporation shares for some of
    their Visioneer shares and the remainder of their Visioneer shares will be
    converted into cash.
 
    In addition, the number of shares that will be converted into cash may be
    increased based on a provision in the merger agreement called the net book
    value adjustment. The actual number of shares converted into cash will
    depend upon the amount of the net book value adjustment.
 
    To review the consideration to be received by Visioneer and ScanSoft
    stockholders in the merger, along with the proration and book value
    adjustment calculations, see pages 37-40.
 
    Examples:
 
        - The exchange agent receives requests to convert exactly 5,097,000
          shares into cash.
 
           (A) You elected to convert all 100 of your shares into cash. You will
               receive $206.00 in exchange for your 100 shares at $2.06 per
               share.
 
           (B) You elected to receive shares of Surviving Corporation common
               stock and no cash for your 100 shares. You will receive 100
               shares of Surviving Corporation common stock in exchange for your
               100 shares of Visioneer common stock.
 
        - The exchange agent receives requests to convert 10,194,000 shares into
          cash.
 
           (A) You elected to convert all 100 of your shares into cash. Since
               the cash election is "oversubscribed" by twice the number of
               shares to be converted into cash, you will receive cash for 50 of
               your 100 shares, or $103.00, and 50 shares of Surviving
               Corporation common stock for the 50 shares that could not be
               converted into cash.
 
           (B) You elected to receive shares of Surviving Corporation common
               stock and no cash for your 100 shares. Because the cash election
               was oversubscribed, you will receive shares of Surviving
               Corporation common stock for all 100 of your shares.
 
        - The exchange agent receives requests to convert 4,000,000 shares into
          cash. The cash election is undersubscribed by 1,097,000 shares
          (5,097,000 - 4,000,000). For purposes of this example, we assume there
          are 19,852,952 shares of Visioneer common stock outstanding (the
          number of outstanding shares as of December 31, 1998).
 
           (A) You elected to convert all 100 of your shares into cash. Because
               the cash election is "undersubscribed," you will receive cash for
               all of your 100 shares, or $206.00.
 
           (B) You elected to receive 100 shares of Surviving Corporation common
               stock and no cash in exchange for your 100 shares. Because the
               cash election is undersubscribed by 1,097,000 shares,
               approximately 7% of the shares that were not requested to be
               exchanged for cash [1,097,000 / (19,852,952 - 4,000,000)] will be
               exchanged for cash. Thus, you will only be able to exchange 93 of
               your 100 shares into shares of Surviving Corporation common stock
               and the remaining 7 shares will be exchanged for cash at $2.06
               per share, or $14.42.
 
    Visioneer will not issue fractional shares. Instead, you will receive cash
    for any fractional share of Surviving Corporation common stock owed to you
    equal to such fraction multiplied by $2.06.
 
                                        4
<PAGE>   11
 
Q: WILL I OWE ANY FEDERAL INCOME TAX AS A RESULT OF THE MERGER?
 
A: Visioneer stockholders will be subject to federal income tax on any cash
   received for Visioneer shares, including fractional shares. No federal income
   tax will be due on the exchange of Visioneer shares for Surviving Corporation
   common stock.
 
    To review federal income tax consequences in greater detail, see page 41.
 
Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?
 
A: We are working toward completing the merger as quickly as possible. In
   addition to Visioneer stockholder approval, Visioneer and ScanSoft must also
   obtain U.S. antitrust approvals. We hope to complete the merger in the first
   quarter of 1999.
 
Q: WHOM SHOULD I CALL WITH QUESTIONS?
 
A: If you have any questions about the merger, please call J. Larry Smart,
   President and Chief Executive Officer of Visioneer, at (510) 608-0300.

THE COMPANIES (PAGES 55-63)
 
VISIONEER, INC.
34800 Campus Drive

Telephone: (510) 608-0300
 
     Visioneer designs, develops and markets intelligent paper and image
management software products which facilitate the imaging, manipulation,
distribution and storage of information on personal computers, multi-function
peripherals and from digital cameras. Visioneer's PaperPort software products
provide an easy-to-use, fast and cost-effective solution for document and image

     In January 1999, Visioneer sold its desktop and sheetfed scanner business
to a newly formed wholly-owned subsidiary of Primax Electronics, Ltd. Primax is
a leading worldwide manufacturer of scanners and is headquartered in Taiwan.
Primax also acquired the "Visioneer" brand name. Visioneer will have rights to
use the name until the effective time of the merger with ScanSoft. Visioneer and
Primax also entered into a software license agreement granting Primax certain
rights to "bundle," market and sell Visioneer PaperPort software with Primax
hardware products, including those purchased from Visioneer.
 
SCANSOFT, INC.

retail, OEM and corporate markets. ScanSoft's products capture and convert paper
documents and photos into digital documents and images, and enhance a user's
ability to organize and share digital documents and images in the office, at

to address the needs of consumers and businesses ranging from home office and
small businesses to medium enterprises and large corporations. All of the
outstanding shares of ScanSoft are owned by Xerox Imaging Systems, Inc., which
is owned by Xerox Corporation. ScanSoft also has outstanding options that are
held by its employees.
 
THE PROPOSED MERGER (PAGE 28)
 
     Visioneer and ScanSoft have entered into a merger agreement dated December
2, 1998. The merger agreement provides that ScanSoft will merge with and into
Visioneer, with Visioneer continuing as the surviving corporation but operating
under the name "ScanSoft, Inc." As part of the Merger, Visioneer will be
amending its certificate of incorporation in the form attached as Annex E to
this proxy statement/prospectus to increase the authorized shares of common and
preferred stock, and to authorize shares of Series B preferred stock to be
issued to Xerox Imaging Systems. The amended certificate of incorporation will
be the certificate of incorporation of the Surviving Corporation. If the merger
is completed, Xerox Imaging Systems, Inc. will acquire a substantial interest in
Visioneer.
 
     The merger agreement provides that the merger will take place only if,
among other things, (1) stockholders holding at least a majority of the
outstanding shares of Visioneer common stock approve the merger and merger
agreement at the special meeting of stockholders, and (2) federal antitrust
clearance is received.

WHAT VISIONEER AND SCANSOFT STOCKHOLDERS WILL RECEIVE IN THE MERGER (PAGE 37)
 
     If the merger is completed:
 
     Visioneer stockholders who choose to exchange their shares for cash will
receive $2.06 per share, and Visioneer stockholders who choose to receive shares
of Surviving Corporation common stock will receive new stock certificates for
shares of Surviving Corporation common stock, subject to proration discussed
below and on page 38. Visioneer stockholders may also elect to receive a
combination of cash and stock. The new stock certificates will have the name
"ScanSoft, Inc." but will otherwise represent the same shares of Visioneer
common stock that the stockholder held before, with the same rights as before.
See "Description of Capital Stock -- Capital Stock Following the Merger."
 
     As described below, the terms of the merger agreement require that the
total number of shares of Visioneer common stock to be exchanged for cash will
be 5,097,000, subject to the book value adjustment discussed on page 39. This
number represents approximately 25% of the outstanding shares of Visioneer.
 
     ScanSoft's shares will be converted into newly issued shares of the
Surviving Corporation's common stock and non-voting convertible Series B
preferred stock. All of ScanSoft's stock options will be converted into
Surviving Corporation stock options. After the merger, Xerox Imaging Systems
will own 45% of the outstanding Surviving Corporation common stock and, together
with the former ScanSoft optionholders, will own 53.8% of the total capital
stock of the Surviving Corporation, after taking into account outstanding
options. In addition, Xerox Imaging Systems will receive a warrant to purchase
approximately 1,836,000 shares of Surviving Corporation common stock. The
warrant will be exercisable only to the extent that any ScanSoft stock option to
be assumed by the Surviving Corporation in the merger is later forfeited.
 
CASH ELECTION AND PRORATION (PAGE 38)
 
     Visioneer stockholders can elect, on or before the date of the special
meeting, to receive cash in exchange for their shares of Visioneer common stock.
Stockholders who do not elect to receive cash will receive shares of Surviving
Corporation common stock in exchange for their shares of Visioneer common stock.
 
     The two companies have designated 5,097,000 as the number of shares of
Visioneer common stock that will be exchanged for cash. This "cash election
number" may be adjusted in certain circumstances to maintain the relative
ownership percentage of the former stockholders of Visioneer and ScanSoft in the
Surviving Corporation.
 
     If the number of shares electing to receive cash exceeds the cash election
number, then the amount of cash distributed to stockholders electing cash will
be proportionately reduced, and those stockholders will receive some shares of
Surviving Corporation common stock in exchange for some of their shares.
 
     If the number of shares electing to receive cash is less than the cash
election number, then the number of shares distributed to stockholders who elect
to receive shares of Surviving Corporation common stock will be proportionately
reduced, and those stockholders will receive cash in exchange for some of their
shares. For a more complete discussion of the proration formulas, see "The
Merger -- Merger Consideration -- Cash Election and Proration for Visioneer
Stockholders." Stockholders who receive cash in the case of a proration may owe
federal income tax on gain realized from shares exchanged for cash. See "Risk
Factors -- Merger-Related Risk Factors -- Federal Income Tax Consequences of
Certain Prorations." See also "The Merger -- Federal Income Tax Consequences."
 
CASH ELECTION PROCEDURE (PAGE 38)
 
     Visioneer stockholders must properly complete and sign the cash election
form, which is being mailed along with this proxy statement/prospectus. The cash
election form, together with all Visioneer Stock certificates duly endorsed in
blank or otherwise in form acceptable for transfer on the books of Visioneer (or
by appropriate guarantee of delivery, as described in stock the cash election
form), must be received by U.S. Stock Transfer Corporation (the "exchange
agent") at one of the addresses listed on the cash election form by 5:00 p.m.
New York time (2:00 p.m. California time) on the date of the special meeting,
February 23, 1999. Visioneer stockholders may change their cash election by
written notice received by the exchange agent prior to 5:00 p.m., New York time,
(2:00 p.m. California time) on February 23, 1999. See "The Merger -- Merger
Consideration-Cash Election Procedure."

FRACTIONAL SHARES (PAGE 40)
 
     Fractional shares of common stock will not be issued in the merger.
Stockholders otherwise entitled to receive a fractional share of common stock
following the merger will be paid cash in lieu of such fractional share, as
described in "The Merger -- Merger Consideration -- No Fractional Shares."
 
CONDITIONS TO THE CONSUMMATION OF THE MERGER (PAGE 81)
 
     The merger will be completed if certain conditions, including the
following, are met:
 
     - the approval of Visioneer stockholders;
 
     - the absence of legal restraints or prohibitions that prevent the
       completion of the merger, including federal antitrust laws; and
 
     - the absence of any inaccuracies made by Visioneer or ScanSoft in their
       representations and warranties in the merger agreement that would result
       in a material adverse effect on such company.
 
TERMINATION OF THE MERGER AGREEMENT (PAGE 83)
 
     The merger agreement may be terminated prior to the effective time of the
merger by mutual written consent or by either ScanSoft or Visioneer if:
 
     - the merger is not consummated by April 30, 1999;
 
     - the merger is prohibited or permanently enjoined by a governmental
       entity; or
 
     - the required number of votes from Visioneer's stockholders is not
       obtained at the special meeting.
 
     Subject to certain conditions, ScanSoft may terminate the merger agreement
if:
 
     - any of Visioneer's representations and warranties are not true and
       correct and cannot be cured within a specified period;
 
     - Visioneer fails to perform a material obligation under the merger
       agreement and such failure cannot be cured within a specified period; or
 
     - the Visioneer board fails to recommend, withdraws, modifies or publicly
       announces in a manner adverse to ScanSoft its approval or recommendation
       of the merger or merger agreement.
 
     Subject to certain conditions, Visioneer may terminate the merger agreement
if:
 
     - any of ScanSoft's representations and warranties are not true and correct
       and cannot be cured within a specified period; or
 
     - ScanSoft fails to perform a material obligation under the merger
       agreement, and such failure cannot be cured within a specified period.
 
TERMINATION FEES AND EXPENSES (PAGE 80)
 
     Visioneer must pay ScanSoft a termination fee of $1.7 million in cash if
the merger agreement is terminated in the following circumstances:
 
     - Visioneer stockholders do not approve the merger and Visioneer's board of
       directors withdrew or modified its recommendation in favor of the merger
       in a manner adverse to ScanSoft prior to the special meeting; or
 
     - Visioneer's board withdraws or modifies its recommendation in favor of
       the merger in a manner adverse to ScanSoft.
 
REGULATORY APPROVALS (PAGE 92)
 
     Visioneer and Xerox, as the parent of ScanSoft, are both required to make
filings with or obtain approvals from certain domestic and international
regulatory authorities in connection with the merger, including U.S. antitrust
authorities. We expect that Visioneer and Xerox will obtain all required
regulatory approvals prior to the special meeting. However, we cannot predict
whether Visioneer and Xerox will obtain all required regulatory approvals on
that timetable, or whether any approvals will include conditions that would be
detrimental to Visioneer or Xerox or the merger as negotiated by the parties.
 
STOCKHOLDERS MEETING (PAGE 25)
 
     Visioneer's board of directors has called a special meeting of its
stockholders to vote on the merger agreement and the merger. The meeting is
scheduled for February 23, 1999 at 10:00 a.m., local time, at Visioneer's
principal executive offices at 34800 Campus Drive, Fremont, California, 94555.
Visioneer is soliciting proxies from its stockholders prior to the stockholders
meeting.

RECORD DATE FOR VOTING ON THE MERGER AGREEMENT (PAGE 26)
 
     You may vote at the special meeting or sign a proxy card if you owned
shares of Visioneer common stock as of the close of business on January 12,
1999, the record date. On the record date 19,852,952 shares of Visioneer common
stock were outstanding. Visioneer stockholders will have one vote for each share
of Visioneer common stock they owned on the record date for purposes of voting
on the merger and merger agreement.
 
STOCKHOLDER VOTE REQUIRED TO APPROVE THE MERGER AND MERGER AGREEMENT (PAGE 26)
 
     The vote of Visioneer stockholders holding at least a majority of the
outstanding shares of Visioneer common stock is required to approve the merger
agreement and the merger. Xerox Imaging Systems, ScanSoft's sole stockholder,
has already approved the merger agreement and the merger.
 
STOCKHOLDERS VOTING AGREEMENT (PAGE 85)
 
     Under a voting agreement certain stockholders of Visioneer who, together,
hold approximately 29% of Visioneer's outstanding common stock, have agreed with
ScanSoft:
 
     - to vote their shares in favor of the merger agreement, the merger, and
       the amendment to Visioneer's certificate of incorporation;
 
     - to irrevocably grant to ScanSoft their proxies to vote their shares of
       common stock in favor of the merger agreement and the merger; and
 
     - to refrain, generally until the earlier of completion of the merger or
       termination of the merger agreement, from transferring their shares
       unless the transferee agrees to be bound by the terms of the voting
       agreement.
 
REVOCABILITY OF PROXIES (PAGE 26)
 
     You may revoke your proxy at any time prior to the special meeting by
executing a new proxy card prior to the stockholders meeting or by attending the
special meeting in person and voting. Merely attending the meeting will not
revoke your proxy.
 
COMPLETION OF MERGER (PAGE 40)
 
     Visioneer and ScanSoft expect to complete the merger as soon as practicable
after Visioneer stockholders approve the merger and the other conditions to the
merger have been met.
FAIRNESS OPINION OF FINANCIAL ADVISOR (PAGE 32)
 
     In deciding to approve the merger, Visioneer's board of directors
considered an opinion from its financial advisor, Broadview International LLC,
as to the fairness of the merger to its stockholders from a financial point of
view. This opinion is attached as Annex C to this proxy statement/prospectus. We
encourage you to read this opinion.
 
VISIONEER REASONS FOR THE MERGER;
RECOMMENDATION TO VISIONEER STOCKHOLDERS (PAGE 30)
 
     Visioneer's board of directors has determined that the terms of the merger
agreement and the merger are in the best interests of Visioneer and its
stockholders. In reaching its decision, Visioneer's board identified several
potential benefits of the merger. These benefits include:
 
     - accelerated expansion of Visioneer's software business;
 
     - greater market presence of the combined entities;
 
     - economies of scale; and
 
     - transition from low margin hardware business.
 
     However, Visioneer's board of directors also recognized that the potential
benefits of the merger may not be realized and that there are a number of other
risks and uncertainties related to the merger. VISIONEER'S BOARD OF DIRECTORS
RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER AGREEMENT AND THE MERGER.
 
RISKS OF THE MERGER (PAGE 16)
 
     In considering whether to approve the merger and merger agreement, you
should consider all of the risks of the merger, including the risks that the
potential benefits of the merger may not be realized, that the Surviving
Corporation's business may not be successful, and that the market price of
Visioneer's common stock may fluctuate and could decline in the future.
Stockholders who elect to receive cash for their common stock will lose the
opportunity to participate in future increases, if any, in the value of the
common stock.

<PAGE>   17
 
     WE ENCOURAGE YOU TO READ THE RISK FACTORS SET FORTH IN THIS PROXY
STATEMENT/PROSPECTUS BEGINNING ON PAGE 16.
 
     - to refrain from directly or indirectly soliciting, initiating or
       encouraging third party proposals to acquire Visioneer.
 
COMPARATIVE PER SHARE MARKET PRICE INFORMATION (PAGE 54)
 
     Visioneer's common stock is quoted on the Nasdaq National Market. On
December 2, 1998, the last trading day before the signing of the merger
agreement, Visioneer common stock closed at $1.50 per share. On January   ,
1999, the last trading day prior to the date of this proxy statement/prospectus,
Visioneer common stock closed at $     per share.
 
LISTING OF SURVIVING CORPORATION COMMON STOCK (PAGE 54)
 
     The shares of Surviving Corporation common stock will be listed on the
Nasdaq National Market under the symbol "SSFT."
 
OTHER INTERESTS OF VISIONEER OFFICERS AND DIRECTORS IN THE MERGER (PAGE 45)
 
     In considering the recommendation of Visioneer's board of directors that
you approve the merger agreement and the merger, you should note that the
officers and directors of Visioneer have interests in the merger that are
different from, or in addition to, your interests. Specifically, as a result of
or in connection with the merger, (1) Visioneer will make certain payments upon
consummation of the merger to certain executive officers totaling approximately
$310,000, (2) Visioneer will also accelerate certain options held by executive
officers and make payments to cash out all vested options of employees who will
not continue employment with Visioneer totaling approximately $200,000 and (3)
Visioneer's officers and directors who will cease to continue in that capacity
after the merger will receive continuing indemnification against certain
liabilities. As a result, Visioneer's directors and officers could be more
likely to vote to approve the merger agreement and the merger than Visioneer
stockholders generally.
 
NO SOLICITATION (PAGE 78)
 
     Visioneer has agreed, subject to some exceptions contained in the merger
agreement, not to initiate or engage in discussions regarding a business
combination with another party other than ScanSoft until the earlier of the
termination of the merger agreement or the date the merger closes.
 
DISSENTERS' RIGHTS (PAGE 26)
 
     If you do not vote for the merger agreement and the merger, you will have
the right under Delaware law to dissent to the merger and request an appraisal
of the value of your Visioneer common stock in connection with the merger.
 
     In order to preserve this right, you must follow the procedures discussed
in Annex D.
 
ACCOUNTING TREATMENT (PAGE 44)
 
     Visioneer and ScanSoft intend the merger to be accounted for as a purchase.
 
IMPORTANT FEDERAL INCOME TAX CONSEQUENCES (PAGE 41)
 
     Visioneer and ScanSoft expect that the exchange of Visioneer stock for
shares of Surviving Corporation common stock and the exchange of ScanSoft stock
for shares of Surviving Corporation common stock and preferred stock will be
tax-free for federal income tax purposes to the stockholders of Visioneer and
ScanSoft.
 
     However, Visioneer stockholders will be subject to federal income tax with
respect to cash received in exchange for Visioneer stock (including cash
received in lieu of fractional shares of Surviving Corporation common stock). In
certain circumstances, that cash may be taxable as ordinary income. Neither
Visioneer nor ScanSoft should become subject to federal income taxes solely as a
result of the merger.
 
     Tax matters are very complicated and the tax consequences to you from the
merger will depend on your own circumstances. You should consult your tax
advisors for a full understanding of all of the tax consequences to you from the
merger.

         UNAUDITED SELECTED PRO FORMA CONDENSED COMBINED FINANCIAL DATA
 
     The following unaudited Selected Pro Forma Condensed Combined Financial
Data are derived from the unaudited Pro Forma Condensed Combined Financial
Statements, appearing elsewhere in this proxy statement/prospectus, which give
effect to the sale of the hardware business of Visioneer to Primax and the
acquisition by Visioneer of ScanSoft on a purchase accounting basis, and should
be read in conjunction with such pro forma financial statements and notes
thereto. In preparing the Pro Forma Condensed Combined Statement of Operations
Data, the operations of the hardware component of Visioneer's business have been
excluded and the ScanSoft operations have been included as if these transactions
had occurred at the beginning of the earliest period presented. In preparing the
Pro Forma Condensed Combined Balance Sheet Data, the hardware assets have been
excluded and the ScanSoft assets have been included as if these transactions had
occurred on September 30, 1998. The pro forma information is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have occurred if the sale of the
hardware business of Visioneer or the acquisition of ScanSoft had been
consummated as of the beginning of the earliest period presented, nor is it
necessarily indicative of the future operating results or financial position of
the combined companies.

                                  RISK FACTORS
 
     This proxy statement/prospectus contains certain forward-looking statements
that involve risks and uncertainties. These statements relate to future plans,
objectives, expectations and intentions. These statements may be identified by
the use of words such as "expects," "believes," "anticipates," "intends" and
"plans" and similar expressions. Actual results could differ materially from
those discussed in these statements. Factors that could contribute to such
differences include, but are not limited to, those discussed below and elsewhere
in this proxy statement/prospectus.
 
MERGER-RELATED RISK FACTORS
 
  Difficulties of Integrating Two Companies
 
     The anticipated benefits of the proposed merger will depend in part on
whether the companies' operations and products can be integrated in an efficient
and effective manner. We cannot guarantee that this will occur. Successful
integration will require integration of each company's products and coordination
of each company's operating procedures, financial controls, development efforts
and sales and marketing efforts. This integration may be difficult to accomplish
smoothly or successfully, and may take longer than we expect. If serious
difficulties are encountered during integration, management will have to divert
its attention from normal business operations to address these issues, which
could have an adverse effect on the Surviving Corporation's business. In
addition, the announcement of the merger could cause potential customers to
cancel or delay orders as the result of uncertainty over the successful
integration of the two companies. Furthermore, there could be an adverse effect
on employee morale and on the ability of the Surviving Corporation to retain key
personnel. Failure to effectively accomplish the integration of the two
companies' operations could have a material adverse effect on the Surviving
Corporation's business, operating results and financial condition.
 
  Substantial Expenses Resulting From the Merger
 
     Visioneer and ScanSoft estimate that they will incur aggregate pre-tax
costs of approximately $2.5 million associated with the merger and the sale of
Visioneer's hardware business, as well as severance costs related to employees
of Visioneer of approximately $410,000, including approximately $310,000 to
certain executive officers. In addition, the Surviving Corporation expects to
incur certain costs in connection with the integration of the two companies.
Such costs cannot now be reasonably estimated, because they depend on future
decisions to be made by management of the Surviving Corporation, but they could
be material. Such costs could relate to the elimination of duplicate facilities
and operations, integration of internal and customer-related activities, and
cancellation and/or overlap of contractual obligations. These costs and expenses
will affect results of operations in the quarter in which the merger is
consummated.
 
     The merger will be accounted for as a purchase and, accordingly, the
acquired assets and liabilities of ScanSoft will be recorded at estimated fair
values. Under the purchase method of accounting, intangibles in the amount of
approximately $11.3 million will be capitalized and non-recurring charges of
approximately $4.2 million relating to in-process research and development will
be recorded in the quarter the merger is consummated. These amounts are
estimates that reflect the most recently available information but will be
affected by the completion of a valuation study that is currently in process.
The completion of the valuation study may result in significant differences from
the preliminary allocation. The amortization of other intangibles after the
merger will have an adverse effect on the results of operations of the Surviving
Corporation.
 
  Failure to Achieve Synergies Could Lead to Decline in Stock Price
 
     The market price of the common stock of the Surviving Corporation may
decline significantly if:
 
     - the integration of the combined companies is not successful;
 
     - the Surviving Corporation does not experience business synergies as
       quickly or to the extent expected by financial analysts; or
 
                                       16
<PAGE>   23
 
     - the effect of the merger on earnings per share and operating results is
       not in line with the expectations of financial analysts.
 
  Business Could Suffer Due to Announcement or Consummation of Merger
 
     The announcement or the consummation of the merger may increase the
likelihood of a number of changes to each of our businesses, any of which could
have a material adverse effect. These risks include the following:
 
     - We could lose key management, development or other personnel. Many of
       Visioneer's senior management have already or will join Primax in
       connection with the sale of Visioneer's hardware business. The senior
       management of the Surviving Corporation will be from ScanSoft.
 
     - Our relationships with our OEM distributors and resellers could
       deteriorate.
 
     - Product returns from customers could increase.
 
     - Product orders could decline.
 
     - Development of new products could be delayed.
 
     If the merger is not completed, each company could be materially and
adversely affected by these changes. Restoring our businesses to their
pre-announcement value could take a long time and be costly. As a result of the
risks outlined above, the failure to consummate the merger could have a material
adverse effect on our business, operating results, financial condition and stock
price.
 
  Potential Dilution of Visioneer Stockholders
 
     Following the merger, we intend to grant options to purchase (and could
grant or sell) additional shares of common stock to members of our management
and to employees. Any such grant or sale, or exercise of any stock option, will
dilute your holdings. See "The Merger--Effect on Visioneer and ScanSoft
Options."
 
  Federal Income Tax Consequences of Receipt of Cash Deemed Provided by
Visioneer
 
     In some circumstances, application of the so-called "constructive
ownership" rules of the federal income tax laws may cause cash, if any, received
by Visioneer stockholders from Visioneer as a result of the Book Value
Adjustment or in lieu of fractional shares to be taxed as ordinary income
(rather than capital gain), even where all of the Visioneer stock actually held
by a particular stockholder is converted into cash in the merger. In addition,
because of the possibility of proration, Visioneer stockholders may not be able
to assure themselves of receiving only cash by making a cash election for all
their shares of Visioneer common stock, nor of receiving only stock by making a
non-cash election for all of their shares of Visioneer common stock. See "The
Merger -- Federal Income Tax Consequences" for a more detailed discussion of the
tax consequences of the merger.
 
RISK FACTORS RELATED TO THE COMPANIES' BUSINESS AND OPERATIONS
 
  Dependence on Developing Market; Rapid Technological Change
 
     The market for digital imaging software and, in particular, for Visioneer's
and ScanSoft's products, is new and rapidly evolving. It is dependent on market
demand for color sheetfed and flatbed scanners, as well as for other paper input
systems. It is characterized by transforming technology and frequent new product
introductions. Developing new products and product enhancements is a complex and
uncertain process requiring high levels of innovation, as well as the accurate
anticipation of technological and market trends. Visioneer's PaperPort software
products and ScanSoft's Pagis and TextBridge products account for most of
Visioneer's and ScanSoft's respective revenues. The companies expect that these
products will continue to account for most of the Surviving Corporation's
revenues for the foreseeable future. Broad market acceptance
 
                                       17
<PAGE>   24
 
of these products is therefore critical to the Surviving Corporation's future
success and will depend in part on the following:
 
     - Our ability and that of our distributors and other industry suppliers to
       convince end users to adopt paper input systems and digital imaging
       software for the desktop.
 
     - Our ability to educate end users about the benefits of digital imaging
       products generally and the specific benefits of our products.
 
     - Our ability to adapt to emerging industry standards and respond to our
       competitors' product announcements.
 
     - Our ability to develop, introduce, upgrade and support competitive new
       products and product enhancements that meet changing customer
       requirements and emerging industry standards.
 
     - Our ability to maintain current market share for our products and
       increase brand-name recognition.
 
     If we are not successful in meeting the goals listed above, we may not be
able to gain broad market acceptance for our products. Further, a decline in
demand for digital imaging products generally, or for Paperport, Pagis and
TextBridge products, in particular, could occur as a result of competitive
technological change or other factors and would have a material adverse effect
on the Surviving Corporation's business, operating results and financial
condition.
 
  Difficulties Associated With Timing of New Product Introduction
 
     The digital imaging software market is characterized by rapid technological
change, evolving customer needs, frequent new product introductions and evolving
industry standards. Rapid product advancements could erode the market position
of the companies' products or render those products obsolete. Our success
depends on how well we are able to manage the transition to new products and new
versions of existing products. The life cycles of the companies' products are
difficult to estimate. Further, it is not unusual in personal computer software
life cycles for the sales volume of new products to increase in the first few
months after their introduction because distributors and resellers purchase
initial inventory during that time. As a product reaches the end of its life
cycle, however, demand for that product tends to fall in anticipation of new
replacement products. Consequently, announcements about new products at the end
of a product life cycle may cause our customers to defer purchasing existing
products, and we may be forced to lower the prices of older products in
anticipation of new releases. This may result in distributors claiming price
protection credits or returning older products to us, and as a result, our
revenues may decline. We cannot accurately predict the exact timing in which a
new product or version will be ready to ship. Moreover, in order to maintain
competitiveness, we must make substantial investments in product development and
testing. We cannot guarantee that we will have sufficient resources to make the
necessary investments or that we will be able to develop new products or new
product features quickly enough to meet market demand. Any delay in the
scheduled release of new products or features, or lack of market acceptance for
such new products or features, may have a material adverse impact on our
business, results of operations and financial condition.
 
  Disposition of Hardware Business: Need for Rebranding of Products; Need for
Services Agreement with Primax
 
     In January 1999, Visioneer sold its hardware business to a wholly owned
subsidiary of Primax Electronics Ltd., which was a principal manufacturer of
Visioneer's flatbed and sheetfed scanners and other hardware products. In this
transaction, Primax purchased substantially all of Visioneer's hardware business
(including the "Visioneer" brand and company name), and it assumed all known
liabilities associated with the hardware business. Upon consummation of the
proposed merger, the Surviving Corporation intends to take steps to rebrand all
Visioneer's software products carrying the Visioneer name so that in the future
all such products will be identified with a new software brand name, such as
ScanSoft or PaperPort. The Surviving Corporation will change its corporate name
to "ScanSoft, Inc." In the same way, Primax will rebrand any hardware products
that carry the PaperPort name so that in the future such products will be
identified with a different name. This rebranding may create confusion for the
Surviving Corporation's customers, including OEM
 
                                       18
<PAGE>   25
 
distributors and end-users, and there will necessarily be an adjustment period
following the sale of the hardware business during which time new brands will
need to be established. Additionally, in connection with the sale of Visioneer's
hardware business to Primax, since many of Visioneer's administrative employees
were hired by Primax, Visioneer intends to enter into an agreement with Primax
that requires Primax to provide the Surviving Corporation with certain ongoing
administrative services (such as office space at Visioneer's current location,
use of telephones, computer systems, payroll and accounting services and
customer and technical support services) for a period of time after the sale of
Visioneer's hardware business. If Primax is unwilling to fulfill its obligations
to provide the Surviving Corporation with interim administrative services, our
ability to conduct business immediately prior to and following the merger could
be adversely impacted.
 
  Dependence on Relationships with Primax and Other OEMs
 
     In connection with the sale of Visioneer's hardware business to Primax,
Visioneer entered into a software license agreement granting Primax certain
rights to "bundle" and sell Visioneer's software products with certain Primax
hardware products. Under the license, Primax must pay the Surviving Corporation
certain minimum annual royalties during the license term. Primax, however, is
not obligated to bundle or sell Visioneer's software products with its hardware
products. Other risks include whether Primax will give sufficient priority to
marketing Visioneer's products, whether Primax will continue to offer
Visioneer's products at all, and whether Primax will elect instead to bundle
software products of our competitors with its hardware products. Any of the
foregoing actions could adversely impact the Surviving Corporation's future
business, results of operations and financial condition since we expect Primax
to become an important OEM partner.
 
     We also rely on other OEM partners to bundle, market and sell our products
with their products. However, there are certain risks associated with such
relationships, including whether sufficient priority will be given by such OEM
partners to marketing our products. In addition, our OEM partners may not
continue to offer our products. If we do not maintain and build our OEM
relationships, our business, operating results and financial condition may
suffer.
 
  Competition
 
     The digital imaging market is highly competitive and subject to rapid
change, with frequent new product introductions and enhancements, and constant
pressure to reduce prices. We believe that the principal competitive factors in
the digital imaging software market include:
 
     - OCR accuracy;
 
     - ease of understanding and use;
 
     - product reliability;
 
     - tolerance for poor media;
 
     - product features and functions;
 
     - price/performance characteristics;
 
     - brand recognition; and
 
     - quality of product support.
 
     Our current competitors include developers of digital image processing
software (including photo-editing software), personal document management
software and scanning software suites and manufacturers of scanners and
multi-function peripheral devices. We also face competition in the market for
packaged OCR application programs and bundled OCR products, both in the retail
channel and in the OEM market. We experience significant price competition in
both the retail channel and the OEM market and expect this to continue. In
addition, our "bundled" OCR products themselves compete with our fully featured
shrinkwrap products. In addition to our current competitors, Microsoft
Corporation and MGI Software offer photo-editing products and could offer
products in this market segment in the future. Increased competition may force
us to
 
                                       19
<PAGE>   26
 
lower our prices, experience decreased gross margins or lose market acceptance.
We face the following challenges from our competitors:
 
     - Certain of our competitors offer products comparable to ours at retail
       prices that are lower than ours.
 
     - Many of our current and potential competitors have longer operating
       histories and significantly greater financial, technical, support, sales,
       marketing, recruiting and other resources.
 
     - Certain of our competitors have greater name recognition and larger
       customer bases than we do.
 
     - Certain of our competitors may be better able to withstand significant
       price decreases or devote greater resources to the development,
       promotion, sale and support of their products than we can.
 
     - Certain of our competitors may be able to develop digital image
       processing software with superior OCR accuracy, ease of understanding and
       use, product reliability, tolerance for poor media, product features and
       functions and price/performance characteristics.
 
     We may not be able to compete successfully against current and future
competitors, especially those with greater financial, technical, support, sales,
marketing, recruiting and other resources. If we are not successful in meeting
the challenges listed above, we may not be able to gain broad market acceptance
for our products and our business, financial condition and operating results may
suffer. Competitive pressures may materially affect our business, operating
results and financial condition.
 
     Further, we expect that some consolidation in the digital imaging software
industry will occur over the next few years through strategic acquisitions or
alliances. We expect increased competition from new entrants, including the
possibility that Microsoft will add digital imaging components to the Windows
operating system. In addition, according to PC Data, Inc., the average retail
price of scanners dropped by 47% for the nine months, ending September 30, 1998,
as compared to the same period in 1997. Based on this historical trend, we
expect that scanner prices will continue to decline in the future. We believe
that the downward price trend of scanners may reduce prices for digital imaging
software products. These changes in the market could result in price erosion,
reduced gross margins or loss of market share, any of which could have a
material adverse effect on our business, operating results and financial
condition.
 
  Pressure on Gross Margin
 
     We may suffer adverse operating results if our gross margin fluctuates.
Retail prices on software products drop quickly. In addition, our competitors
will attempt to offer products which meet or exceed our products' performance
and capabilities. We intend to introduce new software products, software
upgrades and software features in response to anticipated competitive price
pressures and new product introductions. If prices fall faster than we expect or
if we must reduce our prices for any reason, we may experience pressure on our
gross margin. In addition, our gross margin will depend in part on certain
factors listed below:
 
     - Our success in introducing new products to the market and easing out old
       ones.
 
     - Our competitors' prices, products and market share.
 
     - The amount of royalties we receive under our OEM arrangements.
 
     - General economic conditions.
 
     If we are not successful in meeting these challenges, our business,
operating results and financial condition may suffer.
 
  Management of Growth
 
     ScanSoft's business has grown rapidly in the last three years. Total net
revenues increased from $12.0 million in 1996 to $17.8 million in 1997 and $15.5
million in the nine months ended September 30, 1998. The growth of ScanSoft's
business and expansion of its customer base has placed a significant strain on
ScanSoft's management and operations. ScanSoft's expansion has resulted in
substantial growth in the number of its employees, the scope of its operating
and financial systems and the geographic area of its
 
                                       20
<PAGE>   27
 
operations, resulting in increased responsibility for both existing and new
management personnel. ScanSoft's ability to support the growth of its business
will be substantially dependent upon having in place sufficient resources to
conduct sales activity, product development, and customer support services.
 
  Dependence on Distributors and Resellers
 
     We expect to continue to receive a substantial portion of our revenues from
sales through our independent distributors and resellers, but we anticipate that
our dependence on any one independent distributor or reseller will decrease in
the future as we expand distribution channels. Our agreements with distributors
and resellers are not exclusive; many of our distributors and resellers offer
competitive products and are not required to give our products priority. Each of
our distributors and resellers can cease marketing our products with limited
notice and with little or no penalty. If we lose any one of our independent
distributors or resellers, we may not be able to recruit replacements. If our
distributors or resellers reduce or cease their marketing and sales efforts on
our behalf, our business, operating results and financial condition may suffer.
 
  International Sales Risks
 
     We plan to expand our international sales by establishing a more extensive
network of international distributors and resellers. We also plan to develop
versions of our products suitable to the market requirements of particular
foreign countries, such as different languages. We have limited experience in
developing international versions of our products and marketing, distributing,
servicing and supporting such products. We may not be able to develop new or
additional versions of our existing products or successfully market, sell,
deliver, service and support our products in international markets. In
conducting business outside of the United States, we are exposed to the risks
listed below:
 
     - Unexpected changes in regulatory requirements.
 
     - Import and export duties and restrictions.
 
     - Tariffs and other trade barriers.
 
     - Difficulties in staffing and managing foreign operations.
 
     - Longer payment cycles.
 
     - Uncertainties in connection with collecting accounts receivable.
 
     - Political instability.
 
     - Fluctuations in currency exchange rates.
 
     - Logistical difficulties in managing multinational operations.
 
     - Seasonal reductions in business activity during summer months in Europe
       and certain other parts of the world.
 
     - Potentially adverse tax consequences, including our inability to recover
       withholding taxes.
 
     If we are not successful in managing the risks listed above, our business,
operating results and financial condition may suffer. One or more of these
factors could have a material adverse effect on our international operations
and, consequently, on our business, operating results and financial condition.
 
  Quality Control Risks
 
     Our products are complex and may contain certain software errors or
failures which are detected only after we begin to ship a product, especially
when first introduced as new versions or when enhancements are released.
Although we conduct testing during product development, we have at times been
forced to delay commercial release of software until problems were corrected
and, in some cases, have provided enhancements to correct errors in released
software. If we do detect any errors before we ship a product, we might have to
limit product shipment for an extended period of time while we address the
problem. Delay in commercial
 
                                       21
<PAGE>   28
 
release, correction of errors or limiting product shipment could lead to loss of
revenues, credibility with customers and market acceptance of our products. We
would also be exposed to additional warranty and engineering expenses. Despite
our testing and testing by current and potential customers, errors may be found
in software or releases after commencement of commercial shipments, resulting in
loss or delay of revenue or delay in market acceptance, diversion of development
resources, damage to our reputation, or increased service and warranty costs. If
we do not successfully manage our quality control, our business, operating
results and financial condition may suffer.
 
  Dependence on Third-Party Licenses
 
     We rely on certain technology which we license from third parties,
including software which is integrated with our own software and used in our
products to perform key functions and provide additional functionality. Because
our products incorporate software developed and maintained by third parties, we
are, to a certain extent, dependent upon such third parties' ability to maintain
or enhance their current products, to develop new products on a timely and
cost-effective basis, and to respond to emerging industry standards and other
technological changes. Further, these third-party technology licenses may not
always be available to us on commercially reasonable terms.
 
     In the event that our agreements with third-party vendors should fail to be
renewed or the products licensed from such vendors should fail to address the
requirements of our software products, we would be required to find alternative
software products or technologies of equal performance or functionality. There
can be no assurance that we would be able to replace such functionality provided
by software that we currently license from third parties in the event that we
lose the license to such software, such software becomes obsolete or
incompatible with future versions of our products or is otherwise not adequately
maintained or updated. The absence of or any significant delay in the
replacement of that functionality could have a material adverse effect on our
business, operating results and financial condition. Moreover, if we were to
lose any of these technology licenses we might experience product shipment
delays or reductions until equivalent technology were identified, licensed and
used. If we do experience product shipping delays and reductions due to
licensing problems, our business, operating results and financial condition
would suffer.
 
  Risks Associated With Protection of Confidential Information and Proprietary
Rights
 
     We generally enter into confidentiality or license agreements with our
employees, consultants and vendors. We also generally control access to and
distribution of our software, documentation and other proprietary information.
We primarily rely on "shrink wrap" licenses that are not signed by the end-user
customer and, therefore, may not be enforceable under the laws of certain
jurisdictions. Unauthorized parties may attempt to copy aspects of our products
or to obtain and use information that we regard as proprietary. Policing
unauthorized use of our products is difficult and we may not be able to protect
our technology from unauthorized use. Additionally, our competitors may
independently develop technologies that are substantially the same or superior
to ours. In addition, the laws of some foreign countries do not protect our
proprietary rights to the same extent as the laws of the United States. Although
the source code for our proprietary software is protected both as a trade secret
and as a copyrighted work, litigation may be necessary to enforce our
intellectual property rights, to protect our trade secrets, to determine the
validity and scope of the proprietary rights of others, or to defend against
claims of infringement or invalidity. Litigation, regardless of the outcome, can
be very expensive and can divert management efforts. These risks, if not managed
successfully, could have a material adverse effect on our business, operating
results or financial condition.
 
  Dependence on Key Personnel; Risks Associated With Hiring and Retention of
Employees
 
     The companies' rely to a significant extent upon their senior management
teams and other key employees. Competition for such employees is intense. We
cannot guarantee that we will be able to retain our key employees following the
merger. The Surviving Corporation's operations could be materially and adversely
affected if it were unable to retain such key employees, or attract new ones.
From time to time, the Surviving Corporation will need to hire additional or
replacement employees. We may not be successful in hiring,
 
                                       22
<PAGE>   29
 
integrating or retaining new employees. If we are not successful in attracting
or retaining qualified personnel, our business, financial condition and
operating results could suffer.
 
  History of Losses; Fluctuations in Operating Results
 
     ScanSoft has net losses for 1996 and 1997 and for the nine months ended
September 30, 1998. Visioneer also had net losses for its fiscal 1996 and 1997
and for the nine months ended September 30, 1998, although a substantial portion
of those losses were attributable to the hardware business that was sold to
Primax in January 1999. On a pro forma basis, the combined companies had a net
loss for 1997 and for the nine months ended September 30, 1998. The Surviving
Corporation may never become or remain profitable.
 
     The companies' revenues frequently fluctuate from quarter to quarter due,
to a large extent, on the following:
 
     - volume, timing and filling of customer orders;
 
     - reduction in prices in response to competition;
 
     - increased expenditures to pursue new product or market opportunities;
 
     - fluctuation in sales orders, juxtaposed with a significant portion of our
       operating expenses being fixed in advance, based in large part on
       forecasts of future sales;
 
     - inability to adjust operating expenses to compensate for shortfall in
       sales orders against forecast;
 
     - price protection charges in excess of recorded allowances;
 
     - demand for products;
 
     - seasonality;
 
     - customer deferrals in anticipation of new versions of products;
 
     - introduction of new products by the Surviving Corporation or its
       competitors;
 
     - timing of new product acquisitions; and
 
     - timing of significant marketing and sales promotions.
 
     Further, backlog early in a quarter is generally not large enough to assure
than we will meet our revenue target for any particular quarter. A shortfall in
shipments at the end of any quarter may cause operating results for that quarter
to fall significantly short of anticipated levels.
 
     In addition, if we need to reduce our prices in response to price
competition, we will therefore be at a significant disadvantage with respect to
our competitors that have substantially greater resources. Such competitors may
more readily withstand an extended period of downward pricing pressure. In such
event, we may also incur price protection charges from our distributors and
resellers. Any price protection charges in excess of recorded allowances would
have a material adverse effect on our business, operating results and financial
condition.
 
     Due to the foregoing factors, among others, ScanSoft's and Visioneer's
revenues are difficult to forecast and, likewise, the Surviving Corporation's
revenues will be difficult to forecast. The Surviving Corporation intends to
base its expense levels in significant part on its expectations of future
revenue. As a result, the Surviving Corporation expects its expense levels to be
relatively fixed in the short term. The Surviving Corporation's failure to meet
revenue expectations would have a material adverse affect on its business,
operating results and financial condition. Further, an unanticipated decline in
revenue for a particular quarter may disproportionately affect the Surviving
Corporation's net income because a relatively small amount of the Surviving
Corporation's expenses are intended to vary with its revenue in the short term.
As a result, we believe that period-to-period comparisons of ScanSoft's,
Visioneer's or the Surviving Corporation's results of operations are not and
will not necessarily be meaningful, and you should not rely upon them as an
indication of future performance.

  Xerox As a Significant Stockholder
 
     ScanSoft is a wholly owned subsidiary of Xerox Imaging Systems, Inc., which
is a wholly owned subsidiary of Xerox Corporation. After the merger, Xerox will
own approximately 45% of the outstanding common stock of the Surviving
Corporation and all of the outstanding Series B preferred stock of the Surviving
Corporation. In addition, Xerox has the opportunity to acquire additional shares
of Surviving Corporation common stock pursuant to the warrant discussed below.
See "The Merger Agreement and Related Agreements -- Related
Agreements -- Warrant." Immediately after the merger, Xerox will be the largest
stockholder of the Surviving Corporation. Although Xerox will not control the
Surviving Corporation and is restricted for at least two years after the merger
from holding more than 50% of the voting power of the capital stock of the
Surviving Corporation, Xerox will have a strong influence over matters requiring
approval by the Surviving Corporation's stockholders. In addition, Xerox will
have representation on the board of directors which will make important
decisions with respect to the business and affairs of the Surviving Corporation.
 
     Xerox has advised the Surviving Corporation that its current intent is to
hold all of its shares of common stock to be acquired in the merger. However,
there can be no assurance concerning the periods of time during which time Xerox
will maintain its ownership of common stock and the Surviving Corporation.
 
  Year 2000 Risks
 
     Visioneer and ScanSoft both have a number of installed computer systems and
software products that are coded to accept only two digit entries in the date
code field. These date code fields will need to distinguish 21st century dates
from 20th century dates -- the "Year 2000 bug." The Year 2000 bug could lead to
system failures or miscalculations causing disruptions of operations including,
among other things, a temporary inability to process transactions, send
invoices, or engage in similar normal business activities. Visioneer and
ScanSoft are currently in the process of establishing procedures for evaluating
and managing the risks and costs associated with this problem. See "Information
About Visioneer," and "ScanSoft Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Certain Trends." Finally, many
of our customers' and suppliers' operations may be affected by Year 2000
complications. As such, the failure of these customers and suppliers to ensure
that their systems are Year 2000 compliant could have a material adverse effect
on our customers and suppliers, resulting in a material adverse effect on the
Surviving Corporation's business, operating results and financial condition.

                              THE SPECIAL MEETING
 
DATE, TIME AND PLACE OF MEETING
 
     The special meeting of the stockholders of Visioneer will be held at the
principal executive offices of Visioneer at 34800 Campus Drive, Fremont,
California 94555, on February 23, 1999 at 10:00 a.m., local time.
 
MATTERS TO BE CONSIDERED
 
     At the special meeting, the stockholders of Visioneer will be asked to
consider and vote upon a proposal to approve and adopt the merger agreement and
the merger, pursuant to which ScanSoft will merge with and into Visioneer, with
Visioneer as the Surviving Corporation. If the merger is approved, all
outstanding shares of capital stock of ScanSoft will be converted into newly
issued shares of Surviving Corporation common stock and Series B preferred
stock. As of the date of this proxy statement/prospectus, all shares of capital
stock of ScanSoft are owned by Xerox Imaging Systems, Inc. ("XIS"), a wholly
owned subsidiary of Xerox. Outstanding ScanSoft options which are held by
ScanSoft employees will be assumed by the Surviving Corporation and replaced
with options to purchase Surviving Corporation common stock. In addition, XIS
will receive a common stock warrant exercisable for the number of shares equal
to the number of ScanSoft options assumed by the Surviving Corporation which are
forfeited by the holders of those options from time to time after the merger.
XIS will own 45% of the Surviving Corporation common stock and all of the
Surviving Corporation Series B preferred stock outstanding immediately after the
merger. The Surviving Corporation common stock and convertible Series B
preferred stock held by XIS, along with Surviving Corporation common stock
options held by former ScanSoft option holders (and the related common stock
warrant held by XIS), will represent approximately 53.8% of the total equity
capital of the Surviving Corporation on a fully-diluted basis immediately after
the merger, including outstanding options, subject to adjustment as discussed
below under "The Merger -- Merger Consideration -- Book Value Adjustment."
 
     In addition, under the merger agreement, a minimum of 5,097,000 shares of
common stock currently held by the stockholders of Visioneer (representing
approximately 25% of the presently outstanding shares of Visioneer common stock)
will be converted into the right to receive $2.06 per share in cash. Xerox will
provide approximately $10.5 million to be used to acquire such shares. The
remaining 14,755,952 outstanding shares of Visioneer common stock (based on the
number of shares issued and outstanding as of December 31, 1998) will be
exchanged for an equivalent number of shares of Surviving Corporation common
stock upon consummation of the merger. The shares held by Visioneer stockholders
will represent 55% of the Surviving Corporation common stock outstanding
immediately after the merger and approximately 46.2% of the total equity capital
of the Surviving Corporation on a fully-diluted basis immediately after the
merger, including outstanding options, subject to adjustment as discussed below
under "The Merger -- Merger Consideration -- Book Value Adjustment."
 
     Immediately after the merger, based on 19,852,952 shares of Visioneer
common stock outstanding on December 31, 1998 and assuming no book value
adjustment and no transfers of outstanding ScanSoft shares or exercise of vested
ScanSoft options, the Surviving Corporation will have outstanding: (i)
approximately 26,830,000 shares of common stock (of which approximately
12,074,000 shares will be held by XIS and approximately 14,756,000 shares will
be held by Visioneer stockholders); (ii) approximately 3,759,000 shares of
Series B preferred stock (all of which will be held by XIS); (iii) options to
purchase approximately 1,836,000 shares of common stock held by former ScanSoft
optionholders; and (iv) options held by existing Visioneer employees which are
outstanding as of the merger. In addition, XIS will hold a warrant to purchase
approximately 1,836,000 shares of Surviving Corporation common stock
(representing any shares forfeited by ScanSoft optionholders). The merger
agreement is attached as Annex A to this proxy statement/prospectus. See "The
Merger" and "The Merger Agreement and Related Agreements."
 
     VISIONEER'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND RECOMMENDS A VOTE FOR APPROVAL OF THE MERGER AGREEMENT AND THE
MERGER.

REQUIRED VOTE
 
     The affirmative vote of at least a majority of the shares of Visioneer
common stock entitled to vote at the special meeting is required to approve the
merger agreement and the merger. Pursuant to a stockholders voting agreement,
certain investors, which beneficially owned, as of December 31, 1998, an
aggregate of approximately 29% of outstanding Visioneer common stock, have
agreed to vote all shares held by them in favor of the merger agreement and the
merger. A copy of the stockholders voting agreement is attached as Annex B to
this proxy statement/prospectus. See "The Merger Agreement and Related
Agreements -- Related Agreements-Stockholders Voting Agreement."
 
VOTING AND REVOCATION OF PROXIES
 
     Shares that are entitled to vote and are represented by a proxy properly
signed and received at or prior to the special meeting, unless subsequently
properly revoked, will be voted in accordance with the instructions indicated on
the proxy. If a proxy is signed and returned without indicating any voting
instructions, shares represented by such proxy will be voted FOR the proposal to
approve and adopt the merger agreement and the merger.
 
     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before the shares represented by such proxy are voted at
the special meeting by (i) attending and voting in person at the special
meeting, (ii) giving notice of revocation of the proxy at the special meeting,
or (iii) delivering to the Secretary of Visioneer (A) a written notice of
revocation or (B) a duly executed proxy relating to the same shares and matters
to be considered at the special meeting, bearing a date later than the proxy
previously executed. Attendance at the special meeting will not in and of itself
constitute a revocation of a proxy. All written notices of revocation and other
communications with respect to revocation of proxies should be addressed as
follows: Visioneer, Inc., 34800 Campus Drive, Fremont, California 94555,
Attention: President and Chief Executive Officer, and must be received before
the taking of the votes at the special meeting.
 
RECORD DATE; STOCK ENTITLED TO VOTE; QUORUM
 
     Only holders of common stock at the close of business on January 12, 1999
will be entitled to receive notice of and to vote at the special meeting. At the
close of business on the record date, Visioneer had outstanding 19,852,952
shares of common stock. The presence, in person or by proxy, at the special
meeting of the holders of at least a majority of the votes entitled to be cast
at the special meeting is necessary to constitute a quorum for the transaction
of business. Abstentions will be counted as present for the purposes of
determining whether a quorum is present but will not be counted as votes cast in
favor of the merger. Because the vote on the merger requires the approval of a
majority of the votes entitled to be cast by the holders of the outstanding
shares of common stock, abstentions will have the same effect as a negative vote
on the merger. Proxies relating to "street name" shares that are voted by
brokers will be counted as shares present for purposes of determining the
presence of a quorum on all matters, but will not be treated as shares having
voted at the special meeting as to any proposal as to which authority to vote is
withheld by the broker. Brokers will vote shares based upon instructions given
to them. Without instructions, shares held in "street name" will not be voted.
Shares which are not voted will have the same effect as votes against the
merger.
 
STOCKHOLDERS' APPRAISAL RIGHTS
 
     Each stockholder has a right to dissent from the merger, and, if the merger
is consummated, to receive "fair value" for his or her shares in cash by
complying with the provisions of Delaware law, including section 262 of the
Delaware General Corporation Law. A stockholder who wishes to exercise such
rights must deliver to Visioneer, prior to the vote being taken on the merger at
the special meeting, written notice of his or her intent to demand payment for
his or her shares if the merger is effected and dissenting stockholders must not
vote in favor of the merger. The full text of section 262 is attached as Annex D
to this proxy statement/prospectus. See "Stockholders' Appraisal Rights" for a
further discussion of such rights and the legal consequences of voting shares of
common stock in favor of the merger.

SOLICITATION OF PROXIES
 
     Visioneer will bear the cost of the solicitation of proxies and the cost of
printing and mailing this proxy statement/prospectus. In addition to
solicitation by mail, the directors, officers and employees of Visioneer may
solicit proxies from stockholders by telephone, telegram or by personal
interview. Such directors, officers and employees will not receive additional
compensation for any such solicitation but may be reimbursed for reasonable
out-of-pocket expenses. Arrangements will also be made with brokerage houses and
other custodians, nominees and fiduciaries for the forwarding of solicitation
material to the beneficial owners of shares held of record by such persons.
Visioneer will reimburse such custodians, nominees and fiduciaries for their
reasonable out-of-pocket expenses. Corporate Investor Communications, Inc. will
assist in the solicitation of proxies by Visioneer for an estimated fee of
$5,500 plus reasonable out-of-pocket expenses.

                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
     In June 1997, representatives of Visioneer and Xerox had the first of a
series of discussions regarding a possible business combination of the two
companies. In June 1997, Visioneer and Xerox entered into a confidentiality
agreement. These discussions continued through January 1998.
 
     On January 19, 1998, Visioneer retained Broadview International LLC
("Broadview") to investigate potential business combination transactions that
would complement Visioneer's existing business, increase stockholder value and
provide liquidity to Visioneer stockholders. Visioneer and Broadview
subsequently contacted a number of companies, including Xerox, that they
believed could be interested in a business combination with Visioneer.
 
     On January 28, 1998, representatives of Visioneer, Xerox and ScanSoft met
to discuss a possible business combination of Visioneer and ScanSoft. During the
period from January 30, 1998 through late February, Visioneer, through
Broadview, and Xerox, through its financial advisor, Merrill Lynch, exchanged
information regarding the current and past financial performance and business of
Visioneer and ScanSoft.
 
     At a March 3, 1998 board meeting, Visioneer's board of directors discussed
various alternatives to expand Visioneer's software business and exit from its
hardware business, and ScanSoft was discussed as a potential merger candidate.
 
     On March 16, 1998, Xerox proposed the terms on which Xerox was interested
in merging ScanSoft with Visioneer, which assumed Visioneer's disposition of its
hardware business. On April 16, 1998, Visioneer submitted a counter proposal,
which Xerox rejected on April 20, 1998. On June 3, 1998, Visioneer and ScanSoft
met to further discuss merger terms but were unable to reach agreement on price,
structure and other terms.
 
     At a meeting of Visioneer's board of directors on July 2, 1998, Broadview
summarized the status of recent discussions with Xerox and Visioneer's board
resolved to continue discussions with Xerox. On July 7, 1998, Broadview, on
behalf of Visioneer, submitted a new merger proposal to Merrill Lynch. From July
21, 1998 until early August 1998, Visioneer and Xerox, as well as Broadview and
Merrill Lynch, had various discussions regarding the terms of the proposed
merger and the valuation of ScanSoft. On August 5, 1998, Xerox and Visioneer
executed a mutual nondisclosure agreement.
 
     On August 5, 1998, Visioneer entered into a mutual nondisclosure agreement
with a third party interested in a business combination with Visioneer. On
August 11, 1998, Broadview held a telephone conference call with senior
management of such party to explore reasons for a possible business combination
with Visioneer.
 
     In mid-August 1998, Visioneer and ScanSoft discussed Visioneer's plans to
sell its hardware business and Visioneer requested that Broadview assist it in
such sale. On August 21, 1998, Xerox sent Visioneer a letter indicating that it
would consider two alternative structures resulting in a combination of
Visioneer and ScanSoft.
 
     On August 25, 1998, senior management of the third party met with senior
management of Visioneer to discuss the terms of a possible business combination
and to conduct preliminary due diligence on each business.
 
     On September 2, 1998, representatives of Xerox, ScanSoft and Merrill Lynch
met with representatives of Visioneer and Broadview to exchange management
presentations and to conduct business due diligence.
 
     On September 3, 1998, Broadview received a term sheet from the third party
proposing a business combination and on September 5, 1998, Broadview received a
new term sheet from such party modifying the prior term sheet.
 
     On September 8, 1998, Xerox submitted a revised proposal to Visioneer which
included as a condition the disposition of Visioneer's hardware business. On
September 10, 1998, Visioneer informed Xerox that it
 
                                       28
<PAGE>   35
 
would not accept the September 8, 1998 proposal. On September 17, 1998, Xerox
again submitted a revised proposal to Visioneer.
 
     On September 18, 1998, Visioneer held a meeting of its board of directors
at which Broadview reviewed the terms of the September 17, 1998 Xerox proposal
and the proposal from the interested third party and presented pro forma
comparisons of both proposed transactions. Visioneer's board discussed both
proposals and resolved to proceed with exclusive due diligence and negotiations
with the third party. On September 18, 1998, Visioneer informed Xerox and
Merrill Lynch that it would not be able to continue discussions with Xerox and
entered into an exclusivity agreement with the third party. Visioneer and the
third party subsequently met to further negotiate the terms of the proposed
business combination and commence the due diligence process.
 
     On October 8, 1998, Xerox submitted an unsolicited revised merger proposal
and Visioneer, in accordance with the terms of its exclusivity agreement with
the third party, informed Xerox on October 9, 1998 that it was not in a position
to respond. On October 9, 1998, Visioneer sent a letter to the third party at
their request outlining the terms of Xerox's offer.
 
     At an October 14, 1998 meeting of Visioneer's board of directors, Broadview
presented a comparative analysis of the revised Xerox proposal of October 8,
1998 and the proposal of the third party. The board received an update on the
status of negotiations and due diligence between Visioneer and the third party
and discussed various factors in evaluating such offers, including comparative
analyses of the current and future value of such offers and comparative risk
analysis regarding the possibility of consummating each offer. Visioneer's board
of directors also discussed the possibility of extending the exclusivity
agreement between Visioneer and the third party. On October 15, 1998, the
financial advisors of the third party informed Broadview of the third party's
unwillingness to negotiate certain terms, agreement on which was essential to
the third party in order to consummate the proposed combination with Visioneer.
 
     On October 16, 1998 Visioneer held a meeting of its board of directors, at
which Broadview was present, and discussed the revised terms of the third party
offer in comparison with the Xerox proposal of October 8, 1998. Visioneer's
board resolved not to extend the exclusivity agreement with the third party if
an agreement could not be reached. After the meeting, Visioneer and the third
party were unable to reach agreement on terms.
 
     On October 17, 1998, Visioneer reinitiated discussions with Xerox and
discussed modifications to the terms of the October 8, 1998 Xerox proposal that
were requested by Visioneer. On October 18, 1998, Xerox submitted a revised
proposal.
 
     At an October 19, 1998 meeting, Visioneer's board was informed that
discussions with the third party had been terminated. Visioneer's board then
discussed the terms of the revised Xerox proposal and a proposed exclusivity
agreement between Visioneer and Xerox. The board resolved to continue
discussions with Xerox and to execute an exclusivity agreement which was entered
into on October 19, 1998.
 
     On October 21, 1998, members of Xerox, ScanSoft and Visioneer management,
their respective legal advisors and accountants, and Merrill Lynch and Broadview
met to discuss the structure of the proposed transaction, the due diligence
process and the timing of the transaction. Later that day, representatives of
Xerox, ScanSoft and Visioneer commenced their due diligence investigations at
Visioneer's headquarters in Fremont, California.
 
     During the week of November 2, 1998, representatives of Visioneer, Xerox
and ScanSoft met at ScanSoft's facilities in Peabody, Massachusetts to conduct
due diligence. In addition, representatives of Visioneer, Xerox and ScanSoft, as
well as their legal, financial and accounting advisors, held various telephone
conferences to discuss various elements of the proposed transaction and agreed
on certain modifications to the structure of the transaction.
 
     The exclusivity agreement was subsequently extended several times, during
which Visioneer, Xerox, ScanSoft and their respective legal, financial and
accounting advisors continued to negotiate the terms and structure of the
proposed transaction. On November 25, 1998, Visioneer's board of directors held
a meeting at
 
                                       29
<PAGE>   36
 
which Broadview presented its financial analysis of the transaction and
delivered its written opinion that, as of November 25, 1998, the terms of the
proposed merger between Visioneer and ScanSoft were fair, from a financial point
of view, to Visioneer's stockholders. After considering Broadview's presentation
and the factors described in "The Merger -- Recommendation of Visioneer's Board
of Directors; Reasons for the Merger," Visioneer's board unanimously approved
the merger agreement and the merger.
 
     On December 2, 1998, Visioneer and ScanSoft executed the definitive merger
agreement and related agreements.
 
RECOMMENDATION OF VISIONEER'S BOARD OF DIRECTORS; REASONS FOR THE MERGER
 
     Visioneer's board of directors has determined that the merger is in the
best interests of Visioneer and its stockholders. Accordingly, Visioneer's board
has unanimously approved the merger agreement, and unanimously recommends that
Visioneer stockholders vote "FOR" the approval and adoption of the merger
agreement and the merger. In reaching its determination to approve the merger
agreement and the merger, Visioneer's board of directors considered a number of
factors, including:
 
  Expand Software Business
 
     The merger helps Visioneer accelerate the expansion of its software
business through ScanSoft's large number of registered users, established
distribution channels in the retail and OEM markets, and comprehensive product
family. Visioneer believes that ScanSoft's business is complementary to its own
and will enable it to expand its position in the growing digital imaging
software market.
 
  Increase Market Presence
 
     The strategic opportunities for Visioneer's software business are limited
in the market due to Visioneer's size and capital resources. Visioneer should
benefit from a merger with ScanSoft as the combined company will represent a
greater presence and should achieve greater visibility in the market.
 
  Achieve Greater Economies of Scale
 
     The digital imaging software market is becoming increasingly competitive
and price sensitive. By combining each company's engineering, marketing and
operational personnel, the combined company can more efficiently service its
products and customers.
 
  Transition from Hardware Business
 
     At the same time that Visioneer entered into the merger agreement with
ScanSoft, it entered into an agreement with Primax to sell its hardware business
to a new subsidiary of Primax. The sale of Visioneer's hardware assets to Primax
occurred on January 6, 1999. Visioneer's board of directors believes that the
merger enables Visioneer to transition from the hardware scanner business to the
software business. Visioneer's hardware business experienced significantly lower
margins than its software business, although it represented a substantial
portion of Visioneer's revenues. By combining Visioneer's transition from its
hardware business with the expansion of its software business through the
merger, Visioneer believes that it will be able to increase margins and increase
software revenues.
 
     Visioneer's board of directors views the merger as a means to increase the
value of the combined companies to Visioneer's stockholders. In evaluating the
proposed merger, the board considered and discussed a wide variety of factors,
including the details of the merger agreement, Visioneer's and ScanSoft's
respective products and the potential synergies between those products and
markets, the recent trading activity of Visioneer's stock and the financial
terms of the merger agreement. Visioneer's board also discussed each component
of the merger agreement in light of its fairness to Visioneer's stockholders,
projected dilution to existing Visioneer stockholders resulting from the
issuance of additional shares, and the impact of the merger on current employees
of Visioneer. In addition, Visioneer's board considered the advantages and
disadvantages that the merger would present to Visioneer's achievement of its
strategic objectives. As part of the evaluation
 
                                       30
<PAGE>   37
 
process, Visioneer's board reviewed information about the business, operations
and future prospects of both Visioneer and ScanSoft, including Visioneer's
recent operating results, the relative assets, revenues and results of
operations of Visioneer and ScanSoft, and the opinion of Visioneer's financial
advisor, Broadview.
 
     Visioneer's board of directors also considered the following potentially
negative factors:
 
     - the potential disruption of Visioneer's business that might result from
       both employee uncertainty and customer uncertainty as a result of the
       merger and during the combination of the operations of Visioneer and
       ScanSoft;
 
     - the risk that, despite the intentions and the efforts of the parties to
       reassure Visioneer's customers and distributors regarding the combined
       company's intention to support their future sales efforts, the
       announcement of the merger could result in decisions by such customers or
       distributors to delay or cancel purchases of Visioneer products;
 
     - the possibility that the merger might not be consummated, and the effects
       of the public announcement of the merger on Visioneer's revenues and
       operating results, and Visioneer's ability to attract and retain key
       management, marketing and technical personnel;
 
     - the risk that the anticipated benefits of the merger may not be realized;
       and
 
     - the other risks described above under "Risk Factors."
 
     After considering the foregoing factors, Visioneer's board of directors
unanimously approved the merger agreement and the merger, and recommended that
the stockholders of Visioneer approve and adopt the merger agreement and the
merger. In view of the wide variety of factors considered, both positive and
negative, Visioneer's board did not find it practicable to, and did not,
quantify or otherwise assign relative weights to the specific factors
considered.
 
XEROX'S REASONS FOR THE MERGER
 
     Xerox believes that the merger of Visioneer with ScanSoft represents a
means to both enhance Visioneer stockholder value and to realize the objectives
of Xerox's investment in ScanSoft. Xerox believes that the merger between
Visioneer and ScanSoft has the potential to produce benefits to the combined
company that would not be obtainable by either company on an independent basis.
These potential benefits include significant technology and cost synergies, the
rationalization and expansion of a number of key OEM relationships and an
expansion of retail channel opportunities. Xerox believes the merger will result
in a company better positioned to become a leader in software products for
document capture, recognition and communications. Xerox also believes that the
merger will produce significant benefits for ScanSoft's customers, as the
combined company will be better positioned to respond to customer demands for
products that are both powerful and easy to use.
 
SCANSOFT'S REASONS FOR THE MERGER
 
     ScanSoft expects the merger to benefit the newly formed company in a
variety of ways. The combined company may be able to offer products targeted to
a range of customers, including those in home and small office environments, and
enterprise customers who are just now being offered network scanning devices.
The combined company may also be able to introduce its products and technology
to millions of customers annually through relationships with a number of the
other party's OEMs not available to either company on an independent basis.
These OEM relationships include Brother, Agfa, Epson, Mustek, Xerox, Primax,
Canon, IBM, Apple, Symantec, and others. ScanSoft also expects the combination
will enhance international sales through ScanSoft's existing channels in the
United Kingdom, Germany and France, as well as Visioneer's channels in Asia. The
merger should also result in the optimization of North American product
distribution, as the combined company can leverage both companies' existing
retail channels of computer and office superstores.
 
     The merger will afford the newly combined company the additional advantage
of greater size and market presence. ScanSoft believes that this is necessary to
achieve market share goals as it competes for customers
 
                                       31
<PAGE>   38
 
against larger and better-funded competitors. Furthermore, ScanSoft believes the
increased size and the publicly traded equity of the combined company will
better enable the combined company to attract and retain qualified employees.
Additionally, ScanSoft believes that the increased size and visibility of the
newly combined company will provide additional distribution opportunities,
including Internet marketing.
 
OPINION OF VISIONEER'S FINANCIAL ADVISOR
 
     Visioneer engaged Broadview to act as its financial advisor and requested
that Broadview render an opinion regarding the fairness, from a financial point
of view, to Visioneer's stockholders, of the consideration to be received in the
merger by Visioneer stockholders. At the meeting of Visioneer's board of
directors held on November 25, 1998, Broadview rendered its written opinion
that, as of November 25, 1998, based upon and subject to the various factors and
assumptions set forth in its opinion, the consideration was fair, from a
financial point of view, to the Visioneer stockholders.
 
     The text of Broadview's opinion, which sets forth assumptions made, matters
considered, and limitations on the review undertaken, is attached as Annex C to
this proxy statement/prospectus. This summary of the opinion is qualified in its
entirety by reference to the full text of the opinion.
 
     In rendering its opinion, Broadview, among other actions:
 
     - reviewed the terms of the draft of the merger agreement dated November
       23, 1998 and the associated exhibits which contained the terms set forth
       in the definitive merger agreement relevant to Broadview's opinion;
 
     - reviewed the terms of the draft of the asset purchase agreement dated
       November 11, 1998 related to the sale of the hardware business and the
       associated exhibits which contained the terms set forth in the definitive
       asset purchase agreement relevant to Broadview's opinion;
 
     - reviewed Visioneer's annual report and Form 10-K for the fiscal year
       ended December 31, 1997, including the audited financial statements, and

       including the unaudited financial statements;
 
     - reviewed certain internal financial and operating information, including
       quarterly projections through December 31, 1999, relating to Visioneer
       and prepared and furnished by Visioneer management;
 
     - participated in discussions with Visioneer management concerning the
       operations, business strategy, current financial performance and
       prospects for Visioneer;
 
     - discussed with Visioneer management its view of the strategic rationale
       for the merger;
 
     - reviewed the recent reported closing prices and trading activity for
       Visioneer common stock;
 
     - compared certain aspects of the financial performance of Visioneer with
       public companies Broadview deemed comparable;
 
     - reviewed Xerox's annual report and Form 10-K for the fiscal year ended
       December 31, 1997, including the audited financial statements, and
       Xerox's Forms 10-Q and 10-QA for its quarterly period ended September 30,
       1998, including the unaudited financial statements;
 
     - reviewed ScanSoft's unaudited quarterly income statements for the fiscal
       year ended December 31, 1997 and ScanSoft's unaudited quarterly income
       statements for the nine months ended September 30, 1998, prepared by
       ScanSoft management;
 
     - reviewed certain internal financial and operating information, including
       projections through December 31, 1999, relating to ScanSoft prepared by
       ScanSoft management;
 
     - reviewed Visioneer management due diligence findings regarding ScanSoft's
       business;
 
     - participated in discussions with ScanSoft management concerning the
       operations, business strategy, financial performance and prospects for

                                       32
<PAGE>   39
 
     - discussed with ScanSoft management its view of the strategic rationale
       for the merger;
 
     - compared certain aspects of the projected financial performance of the
       surviving corporation with public companies Broadview deemed comparable;
 
     - analyzed available information, both public and private, concerning other
       mergers and acquisitions Broadview believed to be comparable in whole or
       in part to the merger;
 
     - reviewed recent equity analyst reports covering Visioneer and Xerox;
 
     - reviewed projections through December 31, 2003 for the surviving
       corporation prepared by ScanSoft management and provided by Xerox's
       financial advisors;
 
     - reviewed preliminary correspondence with the Commission and discussed
       issues with Visioneer management and Visioneer's tax and accounting
       advisors regarding the accounting treatment of the transaction;
 
     - participated in negotiations and discussions related to the merger among
       Visioneer, Xerox, ScanSoft and their financial and legal advisors; and
 
     - conducted other financial studies, analyses and investigations as
       Broadview deemed appropriate for purposes of its opinion.
 
     In rendering the opinion, Broadview relied, without independent
verification, on the accuracy and completeness of all the financial and other
information that was publicly available or furnished by Visioneer, ScanSoft, or
Merrill Lynch, including without limitation, the representations and warranties
contained in the merger agreement and the unaudited financials of ScanSoft.
Broadview assumed that the financial projections were reasonably prepared and
reflected the best available estimates and good faith judgments of the
management of Visioneer and ScanSoft as to the future performance of Visioneer,
ScanSoft, and the surviving corporation, as applicable. Broadview did not make
or obtain an independent appraisal or valuation of any of Visioneer's or
ScanSoft's assets. Broadview assumed that the hardware sale would be consummated
in accordance with its terms prior to or contemporaneously with the consummation
of the merger. Broadview also assumed that the merger would be accounted for as
a purchase transaction under generally accepted accounting principles, whereby
Visioneer is to be considered the buyer. With regard to any analyses relating to
valuations of comparable public companies, the share prices used were for the
close of trading on November 24, 1998, the last trading day before Visioneer's
board of directors met to give final consideration to the proposed merger.
 
     The following is a summary explanation of the various sources of
information and valuation methodologies employed by Broadview in conjunction
with rendering its opinion regarding the proposed merger. Note that as the sale
of Visioneer's hardware business to a third party is a condition to the merger,
Broadview's analysis was based on actual and projected results of Visioneer's
software business only and reflects the anticipated effects of the proposed sale
of Visioneer's hardware business. Accordingly, all references to Visioneer refer
only to the software business of Visioneer, Inc. as affected by the assumed sale
of the hardware business, unless otherwise noted. Historical operating results
were adjusted to reflect only the software business' operating history and were
prepared and provided to Broadview by Visioneer management. For analyses that
examine the historical prices and performance of Visioneer's publicly traded
common stock, Broadview used market prices, which necessarily included
considerations the public market made for Visioneer's hardware business.
 
  Present Value of Projected Share Price Analysis
 
     Based on results of the public company comparables analysis described
below, Broadview calculated the per share present value of Visioneer shares,
assuming pro rata conversion of Visioneer shares into shares in the surviving
corporation and that all holders of Visioneer shares elected to receive cash.
This analysis was performed based on projected 1999 financial results prepared
by ScanSoft management, with implied pro rata share prices discounted from
January 30, 2000 (assuming 1999 financial results are publicly announced thirty
days subsequent to year end) to November 24, 1998 at discount rates ranging from
25% to 40% assuming the
 
                                       33
<PAGE>   40
 
consummation of the merger. Based on this analysis, Broadview calculated
potential pro rata per share present values of shares to be received by holders
of Visioneer shares ranging from $0.68 to $1.14. In addition to performing this
analysis, Broadview calculated the pro rata cash merger consideration as $0.52
per Visioneer share, assuming all Visioneer stockholders elect to participate in
the cash election.
 
  Stock Performance Analysis
 
     For comparative purposes, Broadview examined the trading history of: (i)
Visioneer common stock from November 28, 1997 to November 24, 1998; and (ii) an
index of the aggregate set of public company comparables versus Visioneer and
the S&P 500 from November 28, 1997 to November 24, 1998.
 
  Public Company Comparables Analysis
 
     Total Market Capitalization/Revenue ("TMC/R"), Total Market
Capitalization/Gross Profit ("TMC/ GP"), Total Market Capitalization/EBIT
("TMC/EBIT"), and Price/Earnings ("P/E") multiples indicate the value public
markets place on companies in a particular market segment. Several public
companies are comparable to both Visioneer and the surviving corporation based
on products offered, business model and market focus. Broadview reviewed twelve
public company comparables in the personal productivity and systems management
software segments of the Information Technology ("IT") market providing data
exchange and image management/ processing products, with Trailing Twelve Month
("TTM") revenue between $10 million and $100 million, from a financial point of
view, including each company's TTM Revenue; TTM Revenue Growth; TTM Gross
Margin; TTM EBIT Margin; TTM Net Margin; Equity Market Capitalization; TTM TMC/R
ratio; TTM TMC/GP ratio; TTM TMC/EBIT ratio; and TTM P/E ratio. The public
company comparables were selected from the Broadview Barometer, a proprietary
database of publicly-traded IT companies maintained by Broadview and categorized
by industry segment. In order of descending TTM TMC/R, the public company
comparables for Visioneer and the surviving corporation consist of: (i)
MySoftware Company Inc.; (ii) Caere Corporation; (iii) Micrografx Inc.; (iv)
Puma Technology Inc.; (v) International Microcomputer Software Inc.; (vi) Smith
Micro Software Inc.; (vii) MetaCreations Corporation; (viii) MapInfo
Corporation; (ix) Jetfax Inc.; (x) Expert Software Inc.; (xi) Datawatch
Corporation; and (xii) Interleaf Inc. The aggregate set of comparables has:
 
     - a TTM TMC/R ratio range of 0.2 to 1.9 with a median of 0.9;
 
     - a TTM TMC/GP ratio range of 0.2 to 2.9 with a median of 1.2;
 
     - a TTM TMC/EBIT ratio range of 12.7 to 46.8 with a median of 15.8; and
 
     - a TTM P/E ratio range of 19.4 to 68.7 with a median of 26.1.
 
     To value Visioneer's ownership in the surviving corporation, Broadview
calculated a range of values for the surviving corporation based on projected
1999 financial results prepared by ScanSoft management. Carefully considering
factors affecting the values of Visioneer, ScanSoft, and the surviving
corporation, Broadview found it appropriate to apply the median values of the
aggregate set of the public company comparables, whose ranges and medians are
described above. Based on ScanSoft management's projected 1999 financial results
for the surviving corporation:
 
     - the range of future equity values for the surviving corporation implied
       by the TTM TMC/R multiples is $17.3 million to $93.5 million with a
       median implied value of $46.6 million;
 
     - the range of future equity values implied by the TTM TMC/GP multiples is
       $16.3 million to $98.2 million with a median implied value of $46.8
       million;
 
     - the range of future equity values implied by the TTM TMC/EBIT multiples
       is $56.2 million to $184.9 million with a median implied value of $68.1
       million; and
 
     - the range of future equity values implied by the TTM P/E multiples is
       $45.5 million to $160.9 million with a median implied value of $61.1
       million.
 
                                       34
<PAGE>   41
 
     Based on Visioneer's size, decreasing revenues over the last four quarters
and marginal profitability, as well as carefully weighting considerations both
positively and negatively affecting value, Broadview used multiples derived from
the lower half of the public company comparables for valuing Visioneer. The
lower half of the set of comparables has:
 
     - a TTM TMC/R ratio range of 0.2 to 0.9 with a median of 0.7;
 
     - a TTM TMC/GP ratio range of 0.2 to 1.2 with a median of 1.0;
 
     - a TTM TMC/EBIT ratio range of 12.7 to 15.7 with a median of 14.2; and
 
     - a TTM P/E ratio range of 19.4 to 25.7 with a median of 22.5.
 
     The per share valuation range of Visioneer implied by the TTM TMC/R
multiples is $0.65 to $1.15 with a median implied value of $1.00. The per share
valuation range implied by the TTM TMC/GP multiples is $0.64 to $1.17 with a
median implied value of $1.08. The per share valuation ranges of Visioneer
implied by the TTM TMC/EBIT and TTM P/E multiples are not considered meaningful
due to the fact that, as a division of a larger company, the cost structure of
Visioneer's software division is not comparable to the public company
comparables.
 
  Transaction Comparables Analysis
 
     Valuation statistics from transaction comparables indicate the Adjusted
Price/Revenue ("P/R") acquirers have paid for comparable companies in a
particular market segment. Broadview reviewed seven comparable public and
private company merger and acquisition transactions from January 1, 1996 through
November 24, 1998 that involved companies similar to Visioneer in products
offered, business model and market focus. Transactions were selected from
Broadview's proprietary database of published and confidential M&A transactions
in the IT industry. These transactions represent seven companies in the personal
productivity and enterprise applications software segments of the IT market
providing graphics and document management utility and application products,
with TTM revenues less than $50 million on the date the transaction was
announced. In order of descending P/R, the transactions used are the acquisition
of: (i) Imagemark Software Labs by Inso Corporation; (ii) Adobe Systems Inc.
(Mastersoft product line) by Inso Corporation; (iii) Southern Computer Systems
Inc. by Scan-Optics Inc.; (iv) Proactive Systems by Jetform Corporation; (v)
Software Publishing Corporation by Allegro New Media Inc.; (vi) Intrafed Inc.
(PowerScan and StageWorks product lines) by Star Technologies Inc.; and (vii)
IMI plc (IMI Computing business) by a management buyout group funded by Lloyd's
Development Capital. The P/R multiples of the seven public and private
transactions range from 0.3 to 2.2 with a median of 1.0. The Visioneer equity
value per share range implied by the P/R multiples of the seven public and
private transaction comparables is $0.76 to $2.14 with a median implied value of
$1.26.
 
  Transaction Premiums Paid Analysis
 
     Premiums paid in comparable public transactions indicate the amount of
consideration paid above a company's equity market capitalization. In this
analysis, the value of consideration paid in transactions involving stock is
computed using the closing stock price on the trading day immediately prior to
announcement. The equity market capitalization of the company receiving
consideration is measured one trading day prior and 20 trading days prior to
announcement. Broadview reviewed 24 comparable M&A transactions from Broadview's
proprietary database involving North American software vendors from January 1,
1997 to November 24, 1998 with total consideration between $20 million and $100
million. In order of descending premium paid 20 trading days prior to the date
of announcement, the software transactions used were the acquisition of: (i)
FullTime Software Inc. by Legato Systems Inc.; (ii) Sulcus Hospitality
Technologies Corporation by Eltrax Systems Inc.; (iii) Consilium Inc. by Applied
Materials Inc.; (iv) Concentra Corporation by Oracle Corporation; (v) Accugraph
Corporation by Architel Systems Corporation; (vi) CUSA Technologies by Fiserv
Inc.; (vii) TeleBackup Systems Inc. by VERITAS Software Corporation; (viii)
National Health Enhancement Systems Inc. by HBO & Company; (ix) Interactive
Group by Dataworks Corporation; (x) Prism Solutions Inc. by Ardent Software
Inc.; (xi) Kurzweil Applied Intelligence Inc. by Lernout & Hauspie Speech
Products NV; (xii) Globalink Inc. by Lernout & Hauspie
 
                                       35

Speech Products NV; (xiii) Learmonth & Burchett Management Systems Inc. by
PLATINUM Technology Inc.; (xiv) Medicus Systems by QuadraMed Corporation; (xv)
IQ Software Corporation by Information Advantage Software Inc.; (xvi) Andyne
Computing Ltd. by Hummingbird Communications Ltd.; (xvii) Quarterdeck
Corporation by Symantec Corporation; (xviii) Innovative Tech Systems Inc. by
Peregrine Systems Inc.; (xix) DataWorks Corporation by Platinum Software
Corporation; (xx) Red Brick Systems Inc. by Informix Corporation; (xxi) Compurad
Inc. by Lumisys Inc.; (xxii) Orcad Inc. by Summit Design; (xxiii) Fulcrum
Technologies Inc. by PC DOCS Group International Inc.; and (xxiv) FTP Software
Inc. by NetManage Inc. Based upon Broadview's analysis of premiums paid in
comparable software transactions, Broadview found that:
 
     - Premiums or discounts paid to companies' equity market capitalizations
       one trading day prior to announcement date ranged from a 31.7% discount
       to a 186.7% premium with a median premium of 20.5%;
 
     - Premiums or discounts paid to companies' equity market capitalizations 20
       trading days prior to announcement date ranged from a 26.3% discount to a
       326.6% premium with a median premium of 38.5%;
 
     - The per share valuation range implied by the premiums paid to the share
       prices one trading day prior to announcement date is $0.68 to $2.87 with
       a median implied value of $1.21; and
 
     - The per share valuation range implied by the premiums paid to the share
       prices 20 trading days prior to announcement date is $0.67 to $3.87 with
       a median implied value of $1.26.
 
  Relative Contribution Analysis
 
     A relative contribution analysis measures each of the merging companies'
contributions to items such as revenue and gross profit on a percentage basis.
Broadview examined Visioneer's and ScanSoft's stand-alone relative projected
contributions for 1998 and 1999, based on projections provided by each company's
respective management for revenue and gross profit. ScanSoft's projected
relative contribution for revenue was 60.0% for 1998 and 59.6% for 1999.
ScanSoft's projected relative contribution for gross profit was 60.0% for 1998
and 59.4% for 1999. To compare the relative contributions attributable to both
Visioneer and ScanSoft to their relative ownership of the surviving corporation,
Broadview calculated Visioneer's ownership in the surviving corporation based on
Visioneer's implied relative ownership excluding transactions pertaining to
shares to be redeemed for cash. Based on this analysis, ScanSoft's implied
ownership in the surviving corporation is 38%.
 
  Consideration of the Discounted Cash Flow Valuation Methodology
 
     While discounted cash flow is a commonly used valuation methodology,
Broadview did not employ such an analysis for the purposes of its opinion.
Discounted cash flow analysis is most appropriate for companies which exhibit
relatively steady or somewhat predictable streams of future cash flow. Given the
uncertainty in estimating both the surviving corporation's and Visioneer's
future cash flows and a sustainable long-term growth rate, Broadview considered
a discounted cash flow analysis inappropriate for valuing either the surviving
corporation or Visioneer.
 
  Summary of Valuation Analyses
 
     Taken together, the information and analyses employed by Broadview lead to
Broadview's overall opinion that the consideration to be paid in the merger is
fair to Visioneer stockholders from a financial point of view.
 
     Visioneer's board of directors selected Broadview as its financial advisor
on the basis of Broadview's reputation and experience in the information
technology sector and the computer software industry in particular. Pursuant to
the terms of an engagement letter between Visioneer and Broadview, the fees
payable by Visioneer to Broadview upon delivery of the opinion are fixed. A
substantial portion of Broadview's fee payable under the engagement letter is
contingent on the consummation of the merger. Broadview will be reimbursed by
Visioneer for certain of its expenses incurred in connection with its
engagement. The terms of
 
                                       36
<PAGE>   43
 
the fee arrangement with Broadview, which Visioneer and Broadview believe are
customary in transactions of this nature, were negotiated at arms' length
between Visioneer and Broadview, and Visioneer's board of directors was aware of
the nature of the fee arrangement.
 
     This summary of the presentations by Broadview to Visioneer's board of
directors does not purport to be a complete description of such presentations or
of all the advice rendered by Broadview. Broadview believes that its analyses
and the summary set forth above must be considered as a whole and that selecting
portions of its analyses, without considering all analyses, could create an
incomplete view of the process underlying the analyses set forth in Broadview's
presentations to Visioneer's board of directors and in Broadview's opinion.
Broadview's opinion is necessarily based upon market, economic, financial and
other conditions as they existed and could be evaluated as of the date of the
opinion. Broadview does not express an opinion as to the price at which
surviving corporation common stock will trade at any time. In performing its
analyses, Broadview made numerous assumptions with respect to software industry
performance, personal productivity, enterprise applications and systems
management industry performance and general economic conditions, many of which
are beyond the control of Visioneer, ScanSoft, or the surviving corporation. 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.
 
MERGER CONSIDERATION
 
  Conversion of ScanSoft Capital Stock
 
     All outstanding shares of capital stock of ScanSoft outstanding immediately
prior to the merger will be converted into newly issued shares of Surviving
Corporation common stock and Series B preferred stock. As of the date of this
proxy statement/prospectus, all shares of capital stock of ScanSoft are owned by
XIS. Outstanding ScanSoft options, which are held by ScanSoft employees, will be
assumed by the Surviving Corporation and replaced with options to purchase
Surviving Corporation common stock. In addition, XIS will hold a common stock
warrant exercisable for the number of shares equal to the number of ScanSoft
options assumed by the Surviving Corporation which are forfeited by the holders
of those options from time to time after the merger. Subject to the adjustments
described under "-- Book Value Adjustment" and assuming no transfers of
outstanding ScanSoft shares or exercises of vested ScanSoft options, XIS will
own 45% of the Surviving Corporation common stock and all of the Series B
preferred stock outstanding immediately after the merger. In addition, XIS will
hold a warrant to purchase approximately 1,836,0000 shares of the Surviving
Corporation's common stock (representing any shares forfeited by ScanSoft
optionholders). This will represent approximately 53.8% of the total equity of
the Surviving Corporation on a fully diluted basis immediately after the merger,
subject to the book value adjustment.
 
     Immediately after the merger, and based on 19,852,952 shares of Visioneer
common stock outstanding on December 31, 1998, and assuming no book value
adjustment and no transfers of outstanding ScanSoft shares or exercises of
vested ScanSoft options, the Surviving Corporation will have outstanding:
 
     - approximately 26,830,000 shares of common stock, of which 12,074,000
       shares will be held by XIS and 14,756,000 shares will be held by
       Visioneer stockholders;
 
     - approximately 3,759,000 shares of Series B preferred stock and a warrant
       to purchase approximately 1,836,000 shares of the Surviving Corporation
       common stock (representing any shares forfeited by ScanSoft
       optionholders);
 
     - options to purchase approximately 1,836,000 shares of common stock, which
       will be held by former ScanSoft optionholders; and
 
     - options held by existing Visioneer employees, which are still outstanding
       as of the merger.
 
     The merger agreement is attached as Annex A to this proxy
statement/prospectus. See "The Merger," and "The Merger Agreement and Related
Agreements."

  Cash Election and Proration for Visioneer Stockholders
 
     Visioneer stockholders as of the record date will be entitled to make an
unconditional election on or prior to the date of the special meeting to receive
$2.06 per share. If the number of shares exceeds the cash election number of
5,097,000 shares, then the number of shares receiving cash will be reduced to a
number determined by multiplying the total number of shares electing cash by a
proration factor determined by dividing 5,097,000 by the total number of shares
electing to receive cash. The balance of the shares electing cash will be
converted into shares of Surviving Corporation common stock.
 
     If the number of shares electing cash is less than 5,097,000, then all
shares electing cash will receive $2.06 per share and a certain number of shares
not electing cash, excluding any dissenting shares, will nevertheless receive
$2.06. That number will be determined by multiplying the total number of shares
of Visioneer common stock outstanding, other than shares electing cash and
dissenting shares, by a proration factor determined by dividing (x) the
difference between 5,097,000 and the number of shares electing cash by (y) the
total number of shares of Visioneer common stock outstanding, other than shares
electing cash and dissenting shares.
 
     If a Visioneer stockholder elects to receive shares of Surviving
Corporation common stock and receives cash as a result of the proration
procedures described above, such stockholder may receive dividend treatment
(rather than capital gain treatment) for any cash treated as received in the
merger from Visioneer as a result of such proration procedures (whether by
virtue of the Book Value Adjustment or cash in lieu of fractional shares). See
"Risk Factors -- Merger-Related Risk Factors -- Federal Income Tax Consequences
of Receipt of Cash Deemed Provided by Visioneer" and "The Merger -- Federal
Income Tax Consequences."
 
  Cash Election Procedure
 
     A cash election form is being mailed along with this proxy
statement/prospectus to Visioneer stockholders as of the record date. For a cash
election to be effective, stockholders must properly complete the form and
return it together with all certificates for shares of common stock held by such
holder, duly endorsed in blank or otherwise in form acceptable for transfer on
the books of Visioneer (or by appropriate guarantee of delivery as set forth in
the cash election form), to the exchange agent at one of the addresses listed on
the cash election form and not revoke the cash election, by 5:00 p.m. New York
time (2:00 p.m. California time) on February 23, 1999. A cash election form may
be changed by written notice received by the exchange agent prior to 5:00 p.m.,
New York time (2:00 p.m. California time) on February 23, 1999. The
determination of the exchange agent as to whether or not a cash election has
been properly made or revoked, and when such election or revocation was
received, will be binding.
 
  Conversion of Visioneer Common Stock
 
     Under the merger agreement, a minimum of 5,097,000 shares of common stock
currently held by the stockholders of Visioneer (representing approximately 25%
of the presently issued and outstanding shares of Visioneer common stock) will
be converted into the right to receive $2.06 per share in cash. Xerox will
provide approximately $10.5 million to be used to acquire such shares. The
remaining 14,755,952 issued and outstanding shares of Visioneer common stock
(based on the number of shares issued and outstanding as of December 31, 1998)
will be exchanged for an equivalent number of shares of Surviving Corporation
common stock upon consummation of the merger. These shares, held by the
Visioneer stockholders immediately prior to the merger, will represent 55% of
the Surviving Corporation common stock outstanding immediately after the merger
and approximately 46.2% of the total equity capital of the Surviving Corporation
on a fully diluted basis subject to the book value adjustment as discussed
below.
 
     In general, subject to certain exclusions and the book value adjustment
discussed below, each share of Visioneer common stock electing to receive cash
will receive $2.06 per share, and each share not electing to receive cash will
receive one share of Surviving Corporation common stock for each share of
Visioneer common stock. In the event that greater than 5,097,000 shares elect to
receive cash, then the approximately $10.5 million will be allocated ratably
among the electing shares, and the remaining shares will be converted into
Surviving Corporation common stock. Similarly, if less than 5,097,000 shares
elect to receive cash, then
 
                                       38
<PAGE>   45
 
any remaining balance from the approximately $10.5 million will be allocated
ratably among all shareholders electing to receive stock, and such cash payments
will be in lieu of shares. Visioneer stockholders may therefore experience a
range of actual outcomes, based upon their own actions and actions taken by
other stockholders, as well as the effect of the book value adjustment discussed
below.
 
     Stockholder A owns only 100 shares and elects to receive cash for all
shares. If the total number of shares electing to receive cash is less than or
equal to 5,097,000, stockholders making the cash election will receive cash for
all of such shares, and Stockholder A will receive $206 for his or her shares.
If the total number of shares electing to receive cash is more than 5,097,000,
then the cash election will be "oversubscribed," and the amount of cash
distributed to all stockholders making the election will be prorated as
described above. In that case, Stockholder A will receive cash for a portion of
his or her shares, and shares of Surviving Corporation common stock for the
balance.
 
     Stockholder B owns only 100 shares and elects to receive only shares of
Surviving Corporation. If the total number of shares electing to receive cash is
equal to or greater than 5,097,000, Stockholder B will receive shares of
Surviving Corporation common stock for all of his or her shares. If the total
number of shares electing to receive cash is less than 5,097,000, then the cash
election will be "undersubscribed," and the number of shares distributed to
stockholders electing to receive shares will be prorated. In this case,
Stockholder B will receive cash for a portion of his or her shares, and shares
of Surviving Corporation common stock for the balance. For example, if
stockholders in the aggregate elect to receive cash only with respect to
4,000,000 shares, Stockholder B would be able to receive approximately 93 shares
[14,755,952 / (19,852,952 - 4,000,000) x 100], and would receive cash for the
remaining 7 shares [1,097,000 / (19,852,952 - 4,000,000) x 100]. In the case of
maximum proration (i.e., no stockholder elects to receive cash), Stockholder B
would receive only 74 shares of Surviving Corporation common stock, and would
receive cash for the remaining 26 shares.
 
     Stockholder C owns only 100 shares and elects to receive cash for 50 shares
and shares of Surviving Corporation for 50 shares. If the total number of shares
electing to receive cash is exactly 5,097,000, then Stockholder C will receive
cash for 50 shares and shares of Surviving Corporation common stock for 50
shares. If the total number of shares electing to receive cash is
oversubscribed, then Stockholder C will receive proportionately more shares than
cash. If the total number of shares electing to receive cash is undersubscribed,
then Stockholder C will receive proportionately more cash than shares.
 
     Fractional shares of common stock will not be issued in the merger.
Stockholders otherwise entitled to a fractional share of common stock following
the merger will be paid cash in lieu of such fractional shares determined and
paid as described under "-- No Fractional Shares."
 
     Any shares of common stock owned by Visioneer or ScanSoft will
automatically be retired at the effective time and will cease to exist.
 
  Book Value Adjustment
 
     The number of shares of Visioneer common stock to be exchanged for cash and
the number of shares of Series B preferred stock to be received by XIS will be
subject to adjustment based upon the variance from a predetermined relationship
between the Visioneer net book value and the ScanSoft net book value, each
calculated on a date prior to the merger. If the difference between the
Visioneer net book value and the ScanSoft net book value is higher than the
predetermined variance, then the cash election number of 5,097,000 shares will
be increased by a number of shares equal to the excess of such variance divided
by $2.06. Such additional shares are referred to as the "Additional Cash
Election Shares." Alternatively, in the event that the difference between the
Visioneer net book value and the ScanSoft net book value is less than the
predetermined variance, then the cash election number of 5,097,000 will not
increase. Instead, Visioneer will issue to XIS that number of additional shares
of preferred stock equal to such shortfall divided by approximately $2.06.
 
     The purpose of this book value adjustment is to adjust the consideration
amounts to be received and the relative ownership percentages in the Surviving
Corporation that are contemplated by the merger agreement.
 
                                       39
<PAGE>   46
 
The book value adjustment compensates for changes in the value of either
Visioneer or ScanSoft that occur in the time period (which is expected to exceed
90 days) between the signing of the merger agreement, at which time the deal
terms were set, and the effective time of the merger.
 
  No Fractional Shares
 
     No fractional shares of Surviving Corporation common stock will be issued
in the merger, and the owner of such fractional share interests will not be
entitled to vote or to any rights of a stockholder of the Surviving Corporation
with respect to such fractional interest after the merger. Each stockholder who
would otherwise be entitled to receive a fractional share (after taking into
account all shares of common stock delivered by such holder) will receive, in
lieu thereof, a cash payment (without interest) equal to such fraction
multiplied by $2.06.
 
EFFECTIVE TIME OF THE MERGER
 
     The merger will become effective upon the filing of the Certificate of
Merger with the Secretary of State of Delaware or such later date as is
specified in such Certificate of Merger. The filing of the Certificate of Merger
will occur as soon as practicable on or after the satisfaction or waiver of the
conditions to the merger specified in the merger agreement unless another date
is agreed to in writing by Visioneer and ScanSoft. Subject to certain
limitations, the merger agreement may be terminated by either Visioneer or
ScanSoft if, among other reasons, the merger has not been consummated on or
before April 30, 1999. See "The Merger Agreement and Related
Agreements -- Conditions to the Consummation of the Merger" and
"-- Termination."
 
     As soon as practicable after the effective time, each holder of an
outstanding certificate which represented shares of Visioneer common stock will,
upon surrender to the exchange agent of such certificate and acceptance of the
certificate by the exchange agent, be entitled to receive either cash, a
certificate representing shares of Surviving Corporation common stock, or both,
as outlined above. The exchange agent will accept such certificates when duly
executed and completed in accordance with the instructions on the cash election
form, together with such other documents as may reasonably be required by the
exchange agent. After the effective time, there will be no further transfer on
the records of Visioneer or its transfer agent of certificates representing
shares of common stock which have been converted, in whole or in part, pursuant
to the merger agreement into the right to receive cash. If such certificates are
presented to Visioneer for transfer, they will be canceled against delivery of
cash and, if appropriate, certificates for Surviving Corporation common stock.
Until surrendered as contemplated by the merger agreement, each certificate for
shares of Visioneer common stock will be deemed at any time after the effective
time to represent only the right to receive upon such surrender the
consideration contemplated by the merger agreement. No interest will be paid or
will accrue on any cash payable as consideration in the merger or in lieu of any
fractional shares of retained common stock.
 
     No dividends or other distributions with respect to retained common stock
with a record date after the effective time will be paid to the holder of any
unsurrendered certificate for shares of common stock with respect to the shares
of retained common stock represented thereby and no cash payment in lieu of
fractional shares will be paid to any such holder pursuant to the merger
agreement until the surrender of such certificate in accordance with the merger
agreement. Subject to the effect of applicable laws, following surrender of any
such certificate, there shall be paid to the holder of the certificate
representing whole shares of retained common stock issued in connection
therewith, without interest, (i) at the time of such surrender or as promptly
thereafter as practicable, the amount of any cash payable in lieu of a
fractional share of retained common stock to which such holder is entitled
pursuant to the merger agreement and the proportionate amount of dividends or
other distributions, if any, with a record date after the effective time
theretofore paid with respect to such whole shares of retained common stock, and
(ii) at the appropriate payment date, the proportionate amount of dividends or
other distributions, if any, with a record date after the effective time but
prior to such surrender and a payment date subsequent to such surrender payable
with respect to such whole shares of retained common stock.

<PAGE>   47
 
FEDERAL INCOME TAX CONSEQUENCES
 
     Under currently applicable law, the following are the material U.S. federal
income tax considerations generally applicable to the merger. The tax treatment
described herein may vary depending upon each stockholder's particular
circumstances and tax position. Certain stockholders (including insurance
companies, tax-exempt organizations, financial institutions or broker-dealers,
foreign corporations, persons who are not citizens or residents of the United
States, stockholders who do not hold their shares as capital assets and
stockholders who have acquired their existing stock upon the exercise of options
or otherwise as compensation) may be subject to special rules not discussed
below. No ruling from the IRS nor opinion of counsel will be sought with respect
to the federal income tax consequences discussed herein and, accordingly, there
can be no assurance that the IRS will agree with the conclusions stated herein.
The discussion below is based upon the provisions of the Internal Revenue Code
of 1986, as amended (the "Code"), and regulations, rulings and judicial
decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked or modified so as to result in U.S. federal income tax
consequences different from those discussed below. In addition, this discussion
does not consider the effect of any applicable foreign, state, local or other
tax laws. Each stockholder should consult his or her own tax advisor as to the
particular tax consequences to him or her of the merger, including the
applicability and effect of any foreign, state, local or other tax laws.
 
  Characterization of the Merger for U.S. Federal Income Tax Purposes
 
     The merger is expected to qualify as a reorganization under section 368 of
the Code such that none of Visioneer, ScanSoft or the former ScanSoft
stockholders will recognize gain or loss as a result of the merger for U.S.
federal income tax purposes. In addition, no U.S. federal income tax
consequences will result from the receipt by Visioneer stockholders of shares of
Surviving Corporation common stock in exchange for their Visioneer common stock
(in effect, the retention of such shares of Visioneer common stock). If only
5,097,000 of cash election shares are converted into cash in the merger (i.e.,
there are no Additional Cash Election Shares, as defined in book value
adjustment, above), because that cash will be provided by Xerox, Visioneer
stockholders will be treated as having sold such shares to Xerox for $2.06 per
share. In the event there are Additional Cash Election Shares, then each
Visioneer stockholder receiving cash pursuant to a cash election (whether
pursuant to an actual election or by virtue of proration) will be treated as
having sold a portion of his or her Visioneer stock to Xerox and as having had a
portion of such stock redeemed by Visioneer. The parties intend to take the
position with the IRS that the percentage of a stockholder's Visioneer stock
converted into cash by virtue of a cash election which will be treated as sold
to Xerox will be equal to (i) 5,097,000 divided by (ii) the sum of 5,097,000 and
the number of Additional Cash Election Shares, if any. The remainder of such
stockholder's Visioneer stock converted into cash by virtue of a Cash Election
will be treated as redeemed by Visioneer. The IRS could, however, adopt a
different approach in determining the portion, if any, of a stockholder's
Visioneer stock which is treated as redeemed by Visioneer. See "-- Stockholders
Receiving Cash" below for a discussion of the consequences of cash being deemed
paid in redemption of Visioneer stock.
 
  Stockholders Receiving Cash
 
     As described more fully below, the U.S. federal income tax consequences of
the merger with respect to a particular Visioneer stockholder will depend upon,
among other things, (i) the extent to which a stockholder is deemed to have sold
his or her Visioneer stock to Xerox or is deemed to have had his or her
Visioneer stock redeemed by Visioneer and (ii) whether the redemption of a
holder's Visioneer stock by Visioneer will qualify as a sale or exchange under
section 302 of the Code. First, to the extent that a stockholder is considered
to have sold Visioneer stock to Xerox, such stockholder will recognize either
capital gain or loss (assuming the Visioneer stock is held by such stockholder
as a capital asset) equal to the difference between the amount realized on his
or her deemed sale of Visioneer stock to Xerox (i.e., the cash proceeds properly
allocated to such sale) and the stockholder's adjusted tax basis in such
Visioneer stock. Such gain or loss generally will be long-term capital gain or
loss if the Visioneer stock is held as a capital asset by the stockholder for
more than one year. Second, a stockholder also will recognize either capital
gain or loss equal to the difference between the cash proceeds allocable to the
redemption of such stockholder's Visioneer stock by Visioneer and the
 
                                       41
<PAGE>   48
 
stockholder's adjusted tax basis in such Visioneer stock, to the extent such
redemption is treated as a sale or exchange under section 302 of the Code with
respect to such stockholder and assuming Visioneer is not a collapsible
corporation. Such gain or loss generally will be long-term capital gain or loss
if the Visioneer stock is held as a capital asset by the stockholder for more
than one year. Under section 302 of the Code, a redemption of Visioneer stock
pursuant to the merger will, as a general rule, be treated as a sale or exchange
if such redemption (a) is "substantially disproportionate" with respect to the
stockholder, (b) results in a "complete redemption" of the stockholder's
interest in Visioneer or (c) is "not essentially equivalent to a dividend" with
respect to the stockholder.
 
     In determining whether any of these section 302 tests is satisfied,
stockholders must take into account not only the Visioneer stock that they
actually own, but also any Visioneer stock they are deemed to own under the
constructive ownership rules set forth in section 318 of the Code. Pursuant to
these constructive ownership rules, a stockholder is deemed to own
constructively any Visioneer stock that is owned by certain related individuals
or entities and any Visioneer stock that the stockholder has the right to
acquire by exercise of an option or by conversion or exchange of a security.
 
     The redemption of a stockholder's Visioneer stock will be "substantially
disproportionate" with respect to such stockholder if, among other things, the
percentage of Visioneer stock actually and constructively owned by such
stockholder immediately following the merger is less than 80% of the percentage
of Visioneer stock actually and constructively owned by such stockholder
immediately prior to the merger. Because of the substantial amount of Visioneer
stock which will be held by XIS following the merger, it is expected that the
conversion of Additional Cash Election Shares into cash in the merger will
result in a "substantially disproportionate" redemption of such shares by
Visioneer. Stockholders are nonetheless strongly urged to consult their own tax
advisors with respect to the application of the "substantially disproportionate"
test to their particular facts and circumstances, particularly in view of the
constructive ownership rules.
 
     The redemption of a stockholder's Visioneer stock will result in a
"complete redemption" of a stockholder's interest in Visioneer if either (i) all
the Visioneer stock actually and constructively owned by the stockholder is
redeemed or sold pursuant to the merger or (ii) all the Visioneer stock actually
owned by the stockholder is redeemed or sold pursuant to the merger and the
stockholder is eligible to waive, and does effectively waive in accordance with
section 302(c) of the Code, attribution of all Visioneer stock which otherwise
would be considered to be constructively owned by such stockholder. Because of
the proration procedures in the merger agreement, Visioneer stockholders may not
be able to assure that all their shares of Visioneer common stock will be
converted into cash in the merger, even if they affirmatively elect to receive
cash for all such shares.
 
     Even if the redemption of a stockholder's Visioneer stock fails to satisfy
the "substantially disproportionate" test or the "complete redemption" test
described above, the redemption of a stockholder's Visioneer stock may
nevertheless satisfy the "not essentially equivalent to a dividend" test if the
stockholder's redemption of Visioneer stock pursuant to the merger results in a
"meaningful reduction" in such stockholder's proportionate stock interest in
Visioneer. Whether the receipt of cash by a stockholder will be considered "not
essentially equivalent to a dividend" will depend upon such stockholder's facts
and circumstances. In certain circumstances, even a small reduction in a
stockholder's proportionate equity interest may satisfy this test. For example,
the IRS has indicated in a published ruling that a 3.3% reduction in the
proportionate equity interest of a small (substantially less than 1%)
stockholder in a publicly held corporation who exercises no control over
corporate affairs constitutes such a "meaningful reduction." Stockholders should
consult with their own tax advisors as to the application of this test in their
particular situations.
 
     A Visioneer stockholder may not be able to satisfy one of the above three
tests because of contemporaneous acquisitions of Visioneer stock by such
stockholder or a related party whose Visioneer stock would be attributed to such
stockholder under section 318 of the Code. Stockholders should consult their own
tax advisors regarding the tax consequences of such acquisitions in their
particular circumstances.
 
     If a stockholder cannot satisfy any of the three tests described above and
to the extent Visioneer has sufficient current or accumulated earnings and
profits, such stockholder will be treated as having received a
 
                                       42
<PAGE>   49
 
dividend which will be included in gross income (and treated as ordinary income)
in an amount equal to the cash received (without regard to gain or loss, if
any).
 
     In the case of a corporate stockholder, if the cash paid is treated as a
dividend, such dividend income may be eligible for the 70% dividends-received
deduction. The dividends-received deduction is subject to certain limitations,
and may not be available if the corporate stockholder does not satisfy certain
holding period requirements with respect to the Visioneer stock or if the
Visioneer stock is treated as "debt financed portfolio stock" within the meaning
of section 246A(c) of the Code. Additionally, if a dividends-received deduction
is available, the dividend may be treated as an "extraordinary dividend" under
section 1059(a) of the Code, in which case a corporate stockholder's adjusted
tax basis in the Visioneer stock retained by such stockholder would be reduced,
but not below zero, by the amount of the nontaxed portion of such dividend. By
virtue of section 1011 of the Taxpayer Relief Act of 1997, any amount of the
nontaxed portion of the dividend in excess of the corporate stockholder's
adjusted tax basis in the Visioneer stock retained by such stockholder is
immediately subject to tax in the taxable year of the ex dividend date for the
dividend. Corporate stockholders are urged to consult their own tax advisors as
to the effect of section 1059 of the Code on the adjusted tax basis of their
Visioneer stock.
 
  Foreign Stockholders
 
     The following is a general discussion of certain U.S. federal income tax
consequences of the merger to foreign stockholders. For this purpose, a foreign
stockholder is any person who is, for U.S. federal income tax purposes, a
foreign corporation, a nonresident alien individual, a foreign partnership or a
foreign estate or trust.
 
     Withholding. In the case of any foreign stockholder, the exchange agent
will withhold 30% of the amount treated as paid to redeem the Visioneer stock
(i.e., there are Additional Cash Election Shares) of such stockholder in order
to satisfy certain U.S. withholding requirements, unless such foreign
stockholder proves in a manner satisfactory to Visioneer and the exchange agent
that either (i) the redemption of his or her Visioneer stock pursuant to the
merger will qualify as a sale or exchange under section 302 of the Code, rather
than as a dividend for U.S. federal income tax purposes, in which case no
withholding will be required, (ii) the foreign stockholder is eligible for a
reduced tax treaty rate with respect to dividend income, in which case the
exchange agent will withhold at the reduced treaty rate or (iii) no U.S.
withholding is otherwise required. Foreign stockholders should consult their own
tax advisors regarding the application of these withholding rules.
 
     Information Reporting and Backup Withholding. Visioneer must report
annually to the IRS and to each stockholder the amount of dividends paid to such
stockholder and the backup withholding tax, if any, withheld with respect to
such dividends. Copies of these information returns also may be made available
to the tax authorities in the country in which a foreign stockholder resides
under the provisions of an applicable income tax treaty. Backup withholding
(which generally is a withholding tax imposed at the rate of 31% on certain
payments to persons that fail to furnish certain information under the United
States information reporting requirements) generally will not apply to dividends
paid to a foreign stockholder at an address outside the United States (unless
the payor has knowledge that the payee is a U.S. person). This so-called "mail
box" rule has been eliminated, but only with respect to dividends paid after
December 31, 1999.
 
     Payment of the proceeds of a sale of Visioneer stock by or through a United
States office of a broker is subject to both backup withholding and information
reporting unless the beneficial owner certifies under penalties of perjury that
it is a foreign stockholder and the payor does not have actual knowledge that
such owner is a U.S. person, or otherwise establishes an exemption. In general,
backup withholding and information reporting will not apply to a payment of the
proceeds of a sale of Visioneer stock by or through a foreign office of a
broker. If, however, such broker is, for United States federal income tax
purposes, a U.S. person, a controlled foreign corporation, or a foreign person
that derives 50% or more of his or her gross income for certain periods from the
conduct of a trade or business in the United States, such payments will not be
subject to backup withholding but will be subject to information reporting,
unless (i) such broker has documentary evidence in its records that the
beneficial owner is a foreign holder and certain other conditions are met or
(ii) the beneficial owner otherwise establishes an exemption.

     Any amounts withheld under the backup withholding rules may be allowed as a
refund or a credit against the holder's U.S. federal income tax liability
provided the required information is furnished to the IRS. The U.S. Treasury
Department has promulgated final regulations regarding the withholding and
information reporting rules discussed above, but the new rules are applicable to
payments made after December 31, 1999. In general, the final regulations do not
significantly alter the substantive withholding and information reporting
requirements but rather unify current certification procedures and forms and
clarify reliance standards. Foreign stockholders should consult their own tax
advisors with respect to the impact, if any, of the new final regulations.
 
     ALTHOUGH THE FOREGOING ARE THE MATERIAL U.S. FEDERAL INCOME TAX
CONSIDERATIONS GENERALLY APPLICABLE TO THE MERGER, THE DISCUSSION DOES NOT
ADDRESS EVERY FEDERAL INCOME TAX CONCERN WHICH MAY BE APPLICABLE TO A PARTICULAR
STOCKHOLDER. EACH STOCKHOLDER IS URGED TO CONSULT SUCH STOCKHOLDER'S OWN TAX
ADVISOR TO DETERMINE THE TAX CONSEQUENCES TO SUCH STOCKHOLDER, IN THE LIGHT OF
HIS OR HER PARTICULAR CIRCUMSTANCES, OF THE DISPOSITION OR RETENTION OF
VISIONEER STOCK PURSUANT TO THE MERGER.
 
ACCOUNTING TREATMENT
 
     The merger will be accounted for as a purchase, and accordingly, the
acquired assets and liabilities of ScanSoft will be recorded at estimated fair
values. Under the purchase method of accounting, intangibles in the amount of
approximately $11.4 million will be capitalized and non-recurring charges of
approximately $4.2 million relating to in-process research and development will
be recorded in the quarter the merger is consummated. These amounts are
estimates that reflect the most recently available information but will be
affected by the completion of a valuation study that is currently in process.
The completion of the valuation study may result in significant differences from
the preliminary allocation. The amortization of goodwill and other intangibles
after the merger will have an adverse effect on the results of operations of
Visioneer.
 
EFFECT ON VISIONEER AND SCANSOFT OPTIONS
 
     Visioneer plans to offer to employees whose employment is terminated by
Visioneer prior to the effective time of the merger the right to receive $0.20
per share for each option share held by such employee that is or would have
vested as of the effective time of the merger (including options that will be
accelerated prior to such time), provided that the employee agrees to terminate
all additional outstanding unvested options held by such employee. Options
outstanding at the effective time will remain outstanding after the effective
time in accordance with their terms. Visioneer's option and stock purchase plans
will also remain in effect after the effective time. See "Interests of Certain
Persons in the Merger and Related Matters -- Agreements with Visioneer's
Executive Officers."
 
     At the effective time of the merger, Visioneer will assume each outstanding
option to purchase common stock of ScanSoft issued pursuant to ScanSoft's 1998
Stock Option Plan, whether vested or unvested, and each assumed option will
constitute an option to acquire, on the same terms and conditions (including the
same vesting provisions) as were applicable under such option prior to the
effective time, that number of whole shares of Visioneer common stock equal to
the product of the number of shares of ScanSoft common stock subject to such
option multiplied by the implicit exchange ratio (rounded down to the nearest
whole number). Each assumed option will have an exercise price per share of
Visioneer common stock equal to the quotient obtained by dividing the exercise
price per share of the ScanSoft common stock subject to such option by the
implicit exchange ratio (rounded up to the nearest whole cent). All such
calculations will ignore whether or not such ScanSoft option is exercisable as
of the effective time. At and after the effective time, Visioneer will honor all
obligations under the ScanSoft options and as in effect on the effective date of
the merger agreement.

         INTERESTS OF CERTAIN PERSONS IN THE MERGER AND RELATED MATTERS
 
     In considering the recommendation of Visioneer's board of directors with
respect to the merger agreement and the transactions contemplated thereby,
stockholders should be aware that certain officers and directors of Visioneer
have interests in the merger that are different from, and in addition to, the
interests of stockholders of Visioneer.
 
AGREEMENTS WITH VISIONEER'S EXECUTIVE OFFICERS
 
     Three officers of Visioneer, J. Larry Smart, President and Chief Executive
Officer and a director, Murray Dennis, Vice President of Sales and Marketing,
and Gregory Elder, Controller, have executed employment and non-compete
agreements with Primax V Acquisition Corp., a wholly-owned subsidiary of Primax
Electronics Ltd. Following the closing of the hardware asset sale to Primax,
which occurred on January 6, 1999, Messrs. Dennis and Elder became employed by
Primax, and each received a signing bonus paid by Primax equal to six months of
their Visioneer salary as part of their new employment compensation package.
Each of these employees released Visioneer from its obligations under existing
employment agreements with Visioneer. Mr. Smart, however, will not commence
full-time employment with Primax until the earliest to occur of (i) the closing
of the merger, (ii) the day on which the merger agreement is terminated by
either Visioneer or ScanSoft, or (iii) March 31, 1999. Until such time, Mr.
Smart will continue to serve as President and Chief Executive Officer of
Visioneer and will render services to Primax on a consulting basis pursuant to a
management services agreement between Visioneer, Primax and Mr. Smart. Mr. Smart
will receive payment of six months additional salary by Visioneer upon his
termination of employment. Jay Hanson, Vice President of Engineering, will
receive a payment of six months additional salary upon termination of employment
by Visioneer. Michael T. Burt, Vice President of Operations, will receive a
payment of four months additional salary upon termination of employment by
Visioneer. Pursuant to an engagement letter dated August 11, 1998 between
Visioneer and The Brenner Group LLC, Richard Brenner serves as Visioneer's Chief
Financial Officer. Visioneer pays The Brenner Group hourly fees for Mr.
Brenner's services and has agreed to pay a success fee for completion of the
hardware sale and the merger. Visioneer anticipates that this success fee will
total approximately $90,000. The total amount of payments to Messrs. Smart,
Hanson and Brenner will be approximately $325,000.
 
     In November 1998, Visioneer's board of directors approved the acceleration
of vesting of 50% of unvested options held by Messrs. Dennis, Burt, Elder, and
Hanson upon each individual's termination of employment with Visioneer. Under
this plan, vesting of options to purchase a total of 75,530 shares were
accelerated for Messrs. Dennis and Elder, and vesting of options to purchase a
total of 77,618 shares will be accelerated for Messrs. Hanson and Burt, assuming
closing of the Merger on March 1, 1999. Visioneer will also accelerate the
vesting of certain options held by Mr. Smart in accordance with the vesting
schedules set forth in letter agreements between Visioneer and Mr. Smart dated
April 9, 1997, July 7, 1997 and October 6, 1997. Options to purchase a total of
approximately 151,787 shares held by Mr. Smart will be accelerated assuming
closing of the merger on March 1, 1999.
 
     In November 1998, Visioneer's board of directors also approved offering to
employees, including executive officers, whose employment is terminated by
Visioneer prior to the effective time of the merger the right to receive $0.20
per share for each option share held by such employee that is or would have
vested as of the effective time of the merger (including options that will be
accelerated prior to such time), provided that the employee agrees to terminate
all additional outstanding unvested options held by such employee. Accordingly,
Messrs. Dennis and Elder would receive approximately $30,500 and $3,900,
respectively, for options exercisable as of the date of the hardware sale to
Primax and options accelerated as a result of their termination of employment.
Similarly, Messrs. Smart, Hanson and Burt are expected to receive approximately
$134,000, $16,200, and $17,400 respectively, for options that would be
exercisable as of the closing of the merger (assuming the merger closes on March
1, 1999) and for options accelerated in connection with the closing of the
merger or their termination of employment.

DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE
 
     All Visioneer directors and officers have entered into indemnification
agreements with Visioneer which provide that Visioneer will maintain directors'
and officers' liability insurance and indemnify directors to the full extent
permitted by applicable law. Further, under the terms of the merger agreement,
for a period of six years after the effective time, Visioneer will cause the
Surviving Corporation to maintain the obligations set forth in the
indemnification agreements and to indemnify the current and former officers and
directors of Visioneer, to the extent provided in Visioneer's certificate of
incorporation and bylaws in effect at the date of execution of the merger
agreement. In addition, the Surviving Corporation shall use its reasonable
efforts to maintain for a period of six years directors' and officers' tail
liability insurance which provides at least the same coverage as would be
provided under Visioneer's current directors and officers' liability insurance;
provided, however, the Surviving Corporation will not be required to pay
aggregate premiums for such tail coverage in excess of $250,000.
 
BOARD OF DIRECTORS OF THE SURVIVING CORPORATION
 
     Pursuant to the merger agreement, Visioneer has agreed that, immediately
after the effective time, it will increase the size of its board of directors by
two. After the merger, the board of directors will include two directors
nominated by Xerox, two directors nominated by Visioneer, two independent
directors and Michael Tivnan, who will serve as the Chief Executive Officer of
the Surviving Corporation after the merger. See "The Merger Agreement and
Related Agreements -- Board of Directors and Officers of Surviving Corporation
Following the Merger" and "-- Related Agreements-Voting Agreement."

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
 
     The following unaudited pro forma condensed combined financial statements
give effect to the sale of the hardware assets of Visioneer and to the merger of
Visioneer and ScanSoft, using the purchase method of accounting in accordance
with generally accepted accounting principles. ScanSoft is a subsidiary of
Xerox; accordingly, the results of ScanSoft's operations on a stand-alone basis
may differ. The unaudited pro forma condensed combined financial statements are
based upon the historical financial statements of the respective companies. The
unaudited pro forma condensed combined balance sheet assumes that the merger
took place on September 30, 1998 and combines ScanSoft's September 30, 1998
audited historical balance sheet with Visioneer's September 30, 1998 unaudited
historical balance sheet. The unaudited pro forma condensed combined statements
of operations for the twelve months ended December 31, 1997 and the nine months
ended September 30, 1998 assume the merger took place as of January 1, 1997 and
combine Visioneer's statement of operations for the twelve months ended December
31, 1997 with ScanSoft's statement of operations for the twelve months ended
December 31, 1997 and Visioneer's unaudited condensed statement of operations
for the nine months ended September 30, 1998 with ScanSoft's condensed statement
of operations for the nine months ended September 30, 1998. The unaudited pro
forma condensed combined financial statements are based on the estimates and
assumptions set forth in the notes to such statements. The pro forma
adjustments, including the purchase price allocations, are based on a
preliminary valuation of ScanSoft that has yet to be finalized. The pro forma
adjustments have been made in connection with the development of the pro forma
information for illustrative purposes to comply with the disclosure requirements
of the Commission. The pro forma adjustments included in the unaudited pro forma
condensed combined financial statements are expected to be revised upon the
finalization of the valuation of the assets of ScanSoft acquired by Visioneer.
The unaudited pro forma condensed combined financial statements do not purport
to be indicative of the results of operations for future periods or the combined
financial position or results that would have been realized had the companies
been a single entity during these periods. These unaudited pro forma condensed
combined financial statements should be read in conjunction with the historical
financial statements and related notes thereto of ScanSoft, which are included
elsewhere herein, and the historical financial statements of Visioneer and
related notes thereto included in Visioneer's December 31, 1997 Annual Report on
Form 10-K and September 30, 1998 Quarterly Report on Form 10-Q previously filed
with the Commission and incorporated by reference herein.

                    CONDENSED COMBINED FINANCIAL STATEMENTS
 
 1. THE TRANSACTION
 
     The pro forma condensed combined financial statements reflect the sale of
the hardware assets of Visioneer to Primax, one of Visioneer's primary
manufacturing partners, for the net book value of these assets plus
approximately $1.1 million. In addition, the pro forma condensed combined
financial statements reflect the acquisition of ScanSoft for approximately 7.0
million shares of Visioneer's common stock and 3.8 million shares of Visioneer's
non-voting Series B preferred stock. Additionally, Visioneer will issue
approximately 1.8 million options in exchange for the ScanSoft outstanding
options. The Series B preferred stock is convertible into common stock on a
share for share basis at the election of the holder after two years; however,
the preferred stock is convertible immediately if the holder's ownership of
outstanding Surviving Corporation common stock is less than 30% unless such
conversion results in the holder owning more than 50% of the outstanding
Surviving Corporation common stock. The Series B preferred stock also carries
dividend preferences and has a liquidation preference of $1.30 per share.
Visioneer will grant XIS a ten-year warrant which allows XIS to acquire shares
equal to any vested or unvested options of former ScanSoft employees forfeited
after the merger. The exercise price and the number of shares subject to the
warrant would be the same as that held by the ScanSoft employee. The warrant is
exercisable at any time; however, Xerox may not exercise the warrant prior to
two years from the date of its initial issuance unless, immediately after such
exercise, Xerox owns directly or indirectly a number of outstanding shares of
Surviving Corporation common stock that represents less than 45% of the total
number of shares of Surviving Corporation common stock outstanding immediately
after such exercise. Also, as part of this transaction, at least 5,097,000
shares of Visioneer common stock will be exchanged for cash at $2.06 per share.
The purchase price of the acquisition of ScanSoft is estimated to be $19.7
million which has been determined as follows:

                                                              $19,678
                                                              =======
</TABLE>
 
     The purchase price for pro forma purposes has been allocated to tangible
assets acquired and liabilities assumed based on the book value of ScanSoft's
current assets and liabilities, which management believes approximates their
fair value. In addition, Visioneer management has engaged an independent
appraiser to value the intangible assets, including amounts allocable to
ScanSoft's in-process research and development. The appraisal process is
currently underway and, based on the preliminary appraisal, the value of the
acquired ScanSoft in-process research and development, which will be expensed
immediately, is $4.2 million. The actual amount of acquired in-process research
and development may differ from this estimate. The in-process research and
development relates to ScanSoft's products for which technological feasibility
has not been established and has been estimated utilizing a stage of completion
approach. The resulting estimated net cash flows have been discounted at a rate
of 25%. This discount rate was based on the estimated cost of capital plus an
additional discount for the increased risk associated with in-process
technology.
 
     The allocation of the purchase price is estimated as follows (in
thousands):

              CONDENSED COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
     The number of shares to be issued for the purchase of ScanSoft, and
therefore the purchase price, will be affected by the net book value of each of
Visioneer and ScanSoft on a date prior to the closing of the transaction. The
merger agreement provides for a net book value adjustment. Had the merger been
consummated on September 30, 1998, the effect of the net book value adjustment
would have resulted in the redemption of more than 5,097,000 shares of Visioneer
common stock. No net book value adjustment has been made to the pro forma
condensed combined balance sheet as of September 30, 1998, because such
adjustment is not expected to be representative of the net book value adjustment
that may result upon consummation of the merger.
 
 2. UNAUDITED PRO FORMA CONDENSED COMBINED BALANCE SHEET
 
     The following adjustments were applied to the historical balance sheet of
Visioneer and ScanSoft at September 30, 1998 to arrive at the pro forma
condensed combined balance sheet:
 
     (a)  To record intangible assets acquired at their fair values, which
          includes developed technology, customer base, trademark, trade name
          and workforce.
 
     (b) To record the estimated transaction costs related to the merger.
         Estimated costs include all costs directly incurred as a result of the
         merger agreement including, but not limited to, accountants and
         attorney fees, investment banker fees and other related costs.
 
     (c)  To reflect the estimated one time charge for acquired in-process
          research and development of $4.2 million.
 
     (d) To reflect the cash received from the sale of the hardware business,
         which is equal to the book value of the hardware business net assets
         plus $1.1 million.
 
     (e)  To record payment of outstanding short-term bank borrowings.
 
     (f)  To record the increase in stockholders' equity of Visioneer as a
          result of the issuance of common and preferred shares and valuation of
          the Visioneer options for the purchase of common stock and related
          warrants issued to ScanSoft option holders and XIS, respectively.
 
     (g)  To eliminate the stockholder's equity of ScanSoft as a result of the
          purchase transaction.
 
     (h) To reduce property, plant and equipment to its estimated fair value.
 
     (i)  To eliminate ScanSoft deferred revenue.
 
 3. UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS
 
     The following adjustments were applied to the historical statements of
operations for Visioneer and ScanSoft for the year ended December 31, 1997 and
the nine months ended September 30, 1998 to arrive at the unaudited pro forma
condensed combined statement of operations of the respective periods as though
the acquisition took place on January 1, 1997:
 
     (a) Adjustment to recognize amortization of identified intangibles arising
         from the merger over their estimated useful lives ranging from three to
         seven years.
 
     (b) Shares used in the per share calculation reflect approximately 7.0
         million shares of Visioneer voting common stock issued to stockholders
         of ScanSoft as if they were outstanding from the beginning of each
         period presented. Basic and diluted weighted average shares exclude the
         nonvoting preferred stock, employee stock options and warrants
         outstanding in each period because of the pro forma combined net loss.
 
     (c) Management of Visioneer has allocated the financial activity of
         Visioneer in the Unaudited Pro Forma Condensed Combined Statement of
         Operations for 1997 and the nine months ended
 
                                       52

                          NOTES TO UNAUDITED PRO FORMA
              CONDENSED COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
         September 30, 1998 between the hardware and software components of its
         business. These allocations have been made by Visioneer management
         based upon actual revenues or costs incurred to the extent practical,
         and reasonable estimations made by Visioneer management when actual
         identification was not possible. The allocation of net revenues and
         cost of revenues has been based primarily on specific identification of
         hardware and software revenues and related costs incurred and on
         specific identification of royalty and development revenues. Employees
         performing research and development activities are dedicated primarily
         to either hardware or software development and therefore such costs
         have been allocated primarily based on the number of individuals
         involved in hardware or software development. Sales and marketing costs
         have been allocated based primarily on the number of individuals
         involved in hardware or software related activities. General and
         administrative costs have been allocated by management based on the
         relative revenues of the hardware and software components of the
         business.
 
     The one time charge to expense the fair value of the in-process research
and development has been excluded from the unaudited pro forma condensed
combined statement of operations because of its nonrecurring nature.

     In January 1999 Visioneer sold its desktop and sheetfed scanner business to
a newly formed and wholly-owned subsidiary of Primax Electronics, Ltd. for
approximately $7.0 million. Primax is a leading worldwide manufacturer of
scanners and is headquartered in Taiwan. Primax also acquired the "Visioneer"
brand name, except that Visioneer will have rights to use the name until the
effective time of the merger. Visioneer and Primax also entered into a software
license agreement granting Primax certain rights to "bundle," market and sell
Visioneer PaperPort software with Primax hardware products, including those
purchased from Visioneer.
 
YEAR 2000 COMPLIANCE
 
     We are in the process of assessing the potential effects of the "Year 2000"
millennium change on our business systems and processes, including facilities,
software and components used by our employees, as well as our outsourcing
vendors and critical suppliers. Our Year 2000 project is proceeding on schedule.
The project goal is to ensure that our business is not impacted by the date
transitions associated with the Year 2000.
 
     Our Year 2000 project plan is coordinated by a team that reports to senior
management. The project team is evaluating the Year 2000 compliance of our
business systems and processes, including facilities, software and components
used by our employees, as well as our outsourcing vendors and critical suppliers
whom provide services relating to our business. Our Year 2000 project is
comprised of the following phases:
 
     - Phase 1 -- Inventory all of our business systems and processes, including
       facilities, software and components used by our employees in order to
       assign priorities to potentially impacted systems and services. We expect
       to complete this phase by January 31, 1999.
 
     - Phase 2 -- Assess the Year 2000 compliance of all inventoried business
       systems and processes, including facilities, software and components used
       by our employees and determine whether to renovate or replace any
       non-Year 2000 compliant systems and services. We expect to complete this
       assessment by March 31, 1999.
 
     - Phase 3 -- Complete remediation, if any is required, of any non-compliant
       business systems and processes, including facilities, software and
       components used by our employees and our outsourcing vendors. Conduct
       procurements to replace any other non-Year 2000 compliant business
       systems and processes, including facilities, software and components used
       by our employees and our outsourcing vendors that won't be remediated. We
       expect to complete all remediation efforts, if any are required, by June
       30, 1999.
 
     - Phase 4 -- Test and validate remediated and replacements systems, if any
       such remediation or replacement is required, to ensure inter-system
       compliance and mission critical system functionality. We expect to
       complete testing and validation efforts, if any are required, by July 31,
       1999.
 
                                       55
<PAGE>   62
 
     - Phase 5 -- Deploy and implement remediated and replacement systems, if
       any deployment or implementation is required, after the completion of
       successful testing and validation. We expect to complete the deployment
       and implementation of the remediated or replacement systems, if any is
       required, by September 30, 1999.
 
     - Phase 6 -- Design contingency plan and business continuation plans in the
       event of the failure of business systems and processes, facilities, data
       networking infrastructure, software and components used by our employees
       due to the Year 2000 millennium change. We expect that the initial
       contingency and business continuation plan will be in place by November
       30, 1999.
 
     Based on our inventory and assessment to date, we believe that our internal
mission critical systems are Year 2000 compliant.
 
     Based on our inventory and assessment to date, we believe that our
facilities can be Year 2000 compliant. In addition, we are seeking assurances
from our facilities' landlords and equipment vendors and data circuit providers
regarding the Year 2000 compliance of their facilities and equipment.
 
     At this time, we believe that our incremental remediation costs, if any,
needed to make our current business systems and processes, including facilities,
software and components used by our employees and our outsourcing vendors are
not material. While we are incurring some incremental costs, our costs through
September 30, 1998 are less than $40,000. Our expected total costs, including
remediation and replacements costs, if any, are estimated to between $100,000
and $150,000 over the life of the Year 2000 project.
 
     We are contacting our hardware and software vendors, other significant
suppliers, manufacturers, outsourcing service providers and other contracting
parties to determine the extent to which we are vulnerable to any one of their
failures to achieve Year 2000 compliance for their own systems. At the present
time, we do not expect Year 2000 issues of any such third parties to materially
affect our business.
 
     Should we fail to solve a Year 2000 compliance problem to our critical
business systems-and processes, the result could be a failure or interruption to
normal business operations. The reasonably likely worst case risks inherent in
our business are as follows:
 
     - Despite the assurances of our third-party suppliers, hardware and
       software vendors, and outsourcing service providers regarding the Year
       2000 compliance of their products and services, the potential exists that
       a Year 2000 problem relating to such third-party suppliers, vendors and
       outsourcing service providers products and services could have a material
       impact on our business. We are conducting monthly discussions with our
       critical outsourcing service providers to determine the progress of their
       Year 2000 compliance programs.
 
     - Despite extensive preparation and effort to ensure Year 2000 compliance,
       implementation of our business continuation contingency plan for a very
       short time may be required while we remediate the Year 2000 problem.
 
     Despite our belief that our mission critical computer software applications
and systems are Year 2000 compliant and our expectation that our enhancement
effort will result in Year 2000 compliant systems, we are currently developing a
business continuation contingency plan. We expect to finalize our initial
contingency plan and to complete the testing all existing systems by November
30, 1999.

                           INFORMATION ABOUT SCANSOFT
 
BUSINESS OF SCANSOFT
 
     In 1993, ScanSoft was established as a software business unit of Xerox
Imaging Systems, Inc. ("XIS") a wholly owned subsidiary of Xerox Corporation. On
September 16, 1996, XIS formed a wholly owned subsidiary, ScanSoft, Inc., in
order to focus on the software business. ScanSoft's subsidiary in the United
Kingdom, ScanSoft Europe, Ltd., markets and sells ScanSoft products in Europe.
 
     ScanSoft is a leading provider of digital imaging software products for
retail, OEM and corporate markets. ScanSoft's products capture and convert paper
documents and photos into digital documents and images, and enhance a user's
ability to organize and share digital documents and images in the office, at
home and on the Internet. ScanSoft's products are based on patented OCR and
image processing technologies designed to address the needs of a broad group of
users ranging from consumers and small office to medium-sized businesses and
large corporations.
 
     Growth in the digital imaging software market is driven by the increasing
need to create and use digital images. For example, on-line communication, such
as e-mail and Internet publishing, is driving the need for scanners and digital
cameras to convert existing printed or photographic information into digital
text and images. The desire to store paper by using the personal computer as a
digital filing cabinet is also driving demand for imaging devices. Individuals
can capture images of paper documents, store them in electronic folders, and
index the information so they can be quickly found. In addition, the
proliferation of high quality, low cost color printers is benefiting the digital
imaging industry. Because many personal computer users can now print color
documents and photos, they are able to make color copies at the office and make
high quality prints of captured photos conveniently at home. Other industry
trends that are having a positive effect on the digital imaging market are
increasing computer speeds and lower prices for computer memory (RAM).
 
     ScanSoft's strategy is to target the growing imaging device market through
its core business of consumer and small office/home office ("SOHO") imaging
software. According to InfoTrends Research Group, a market research and
consulting firm, the North American market for flatbed and sheetfed scanners is
expected to exceed six million units in 1998. According to InfoTrends Research
Group, this market is projected to grow by 42% to over nine million units in
1999. The imaging software market is also connected to the multifunction device
and digital camera markets, which are expected to grow rapidly over the next
three years.
 
     ScanSoft's software products include OCR, personal document management and
software suites that offer various combinations of these products and often
third party offerings. ScanSoft believes that its ability to achieve broad
market acceptance of its products will depend on several factors, including, but
not limited to, ease-of-use, OCR accuracy, speed, and overall functionality. In
addition, the ability of ScanSoft's software to integrate with desktop operating
systems, word processing applications, e-mail software, fax applications, image
editing products and Internet publishing tools will affect ScanSoft's ability to
achieve market acceptance for its products. In that regard, ScanSoft's strategy
is to maintain and enhance its technological position by investing in OCR and
image processing technology and strategic business and technology partnerships
with other leading companies.
 
     ScanSoft also provides software in two other emerging markets: enterprise
imaging and Internet imaging software. The enterprise imaging software market
includes high end OCR products and software targeted at the emerging network
scanning market. The network scanning and multifunction market includes devices
from Xerox, Canon, Ricoh, and Hewlett-Packard. Several network multifunction
devices offer scanning options that use client software to convert, edit,
organize and distribute digital documents via fax, e-mail and the Internet.
Currently, ScanSoft bundles client software with Xerox network multifunction
devices. ScanSoft plans to offer client/server software products in the future.
 
     The Internet imaging software market includes products that make it easier
to publish and share paper documents and photos via the Internet. Currently,
ScanSoft's products allow users to capture and convert paper-based documents to
Joint Photographic Experts Group ("JPEG"), Hypertext Mark-up Language
 
                                       57

("HTML") and Portable Document Format ("PDF") files and share photos and
documents via e-mail or as part of an Internet site. Based on the growth of the
Internet, and the increasing number of ways people and organizations are
leveraging the Internet for communication, ScanSoft expects revenue from, and
increased competition in, this market segment.

paper documents into formatted personal computer documents without retyping. It
also provides an image viewer with image editing, selection and annotation
tools. These tools help users enhance an image, select a portion of the image
they want to work with, and add highlights or notes to an image. For more
advanced image editing and photo projects, Pagis Pro integrates a third party
photo editor. Using the XIFF image format, Pagis Pro can store and send
high-quality color document image files that are a fraction of the size of
images saved in a standard image file format, such as Tagged Image File Format
("TIFF"). Pagis Pro supports Windows drag and drop to send images to Windows 95,
Windows 98 or Windows NT compliant applications. Pagis Pro drag and drop is
commonly used to e-mail and fax photos and documents using third party
communication software.
 
     OEM Products. ScanSoft bundles various versions of Pagis and TextBridge
with leading scanner and multifunction device manufacturers and leading
independent software vendors. OEM customers often require ScanSoft to integrate
products with other applications or customize existing products to meet specific
requirements. Therefore, ScanSoft offers OEM customers both packaged products to
bundle and a software developer's toolkit to facilitate the integration of OCR
functionality with other applications.
 
ENABLING TECHNOLOGY
 
     ScanSoft's software is developed using OCR and image processing
technologies, Application Programming Interfaces (APIs), object-oriented
development tools, and modern graphical user-interface designs. In
addition, ScanSoft's products employ commercial text-retrieval database systems,
electronic document format conversion toolkits, and standard scanner device
interfaces.
 
                                       58
<PAGE>   65
 
  API
 
     ScanSoft's TextBridge and PerfectScan APIs are the foundation for the
majority of ScanSoft's applications. These APIs provide an interface to the OCR
and image processing technologies and provide image-to-text conversion, image
processing and cleanup, scanner and digital camera control, image file format
read and write with image compression, and image printing.
 
  OCR
 
     ScanSoft's OCR technology provides image-to-text document conversion. This
technology provides high quality character recognition accuracy with page-layout
retention, including the ability to reconstruct headers, footers, columns,
paragraphs, embedded images, captions, inverted text and character font
attributes. Additionally, the OCR engine provides document export directly to
Rich Text Format ("RTF"), PDF, HTML and ASCII text, and many other industry
standard electronic document formats via third-party conversion technology. The
OCR engine employs a number of technologies to improve document recognition
accuracy. These technologies are described below:
 
     Character/Word Accuracy. Character accuracy refers specifically to
correctly identifying the actual characters in a page image. Traditional OCR
contains basic capabilities for identifying the shapes of the characters through
pattern recognition techniques. The TextBridge OCR engine employs a variety of
different recognition "experts," which work cooperatively in the OCR process.
 
     Segmentation. Segmentation is the process of differentiating between the
text and picture components of a given page image. The segmentation in
TextBridge performs that function as well as identifies the appropriate
lexicographical ordering of the regions of text on the page, so that the final
output will appear in correct read order.
 
     Output Formatting. TextBridge's formatting capabilities make it possible to
reconstruct most compound document formats, including multiple columns, cell
tables, pictures, captions, headers and footers, thereby saving the end-user
reformatting time and effort. The most recent additions to TextBridge's
reformatting abilities include reverse-video (white-on-black) text output and
insets.
 
     Image Processing. ScanSoft's image processing technology provides capture,
enhancement and compression techniques. The heart of the image processing core
engine is page segmentation capabilities which provide the ability to decompose
a page image into its components, including text, pictures, background tints,
and text color. The image processing core engine also provides efficient page
enhancement technologies such as auto-crop, auto-straighten, automatic picture
enhancement, high-speed rendering, line removal, speck removal, tint removal and
forms-field detection.
 
     ScanSoft's advanced image compression technologies employ wavelet, JPEG,
symbol-based and Huffman compression techniques to facilitate the process of
capturing high-quality compound color documents and store them in the compact
XIFF image format. XIFF images are a fraction of the size of images saved in a
standard image file format, such as TIFF. Moreover, the text is clean and
suitable for OCR, faxing or printing.
 
COMPETITION
 
     The digital imaging market is highly competitive and subject to rapid
change along with frequent new product introductions and enhancements, and
constant pressure to reduce prices. ScanSoft believes that the principal
competitive factors in this market include OCR accuracy, ease of understanding
and use, product reliability, product features and functions, price/performance
characteristics, brand recognition, and quality of product support. ScanSoft's
competition within the digital imaging software market ranges from large
corporations to small independent software vendors. ScanSoft also expects to
encounter continued competition, both from established companies and from new
companies that are now developing, or may develop, competing products.
 
     The TextBridge family of OCR products face competition in two markets: the
market for packaged OCR application programs and OEM bundled OCR products.
Several companies offer packaged OCR application
 
                                       59
<PAGE>   66
 
programs through the channel, including companies such as Caere Corporation and
Adobe Corporation and several small independent software vendors. ScanSoft faces
significant price pressure in the retail channel. In the OEM market in which
companies "bundle" the OCR technology with related hardware products, such as
scanners or multifunction peripherals or incorporate OCR technology into third
party application software products, competitors include Caere Corporation and
several small independent software vendors. ScanSoft experiences significant
price competition in the OEM market and expects this to continue. In addition,
the "bundled" OCR products themselves present competition to ScanSoft's fully
featured shrinkwrap products.
 
     The Pagis family of products competes with various products in the digital
imaging software marketplace. In the personal document management segment there
are several competitors, including Visioneer, DocuMagix, Inc. (a division of
JetFax Corporation), Caere Corporation, Newsoft (a subsidiary of UMAX
Corporation), and Eastman Software (a subsidiary of Kodak Corporation). With
decreasing prices driving affordable scanning solutions into the mainstream,
ScanSoft expects to face increasing competition in this product category from a
variety of software developers.
 
     In the scanning software suite segment, ScanSoft products include various
combinations of the products mentioned above and often include photo-editing
capabilities. Competitors include Visioneer and Adobe Corporation. Caere
Corporation has also announced plans to enter this market segment. Microsoft and
MGI Software offer photo-editing products and could offer products in this
market segment in the future.
 
     ScanSoft expects that some consolidation in the digital imaging software
industry will occur over the next few years through strategic acquisitions or
alliances, and ScanSoft expects increased competition from new entrants,
including the possibility that Microsoft will add digital imaging components to
its Windows operating system. In addition, according to PC Data, Inc., the
average retail price of scanners dropped by 47% for the nine months ending
September 30, 1998, as compared to the same period in 1997. Based on this
historical trend, ScanSoft expects that scanner prices will continue to decline
in the future. ScanSoft believes that the downward price trend of scanners may
reduce prices for digital imaging software products. These changes in the market
could result in price erosion, reduced gross margins or loss of market share,
any of which could have a material adverse effect on ScanSoft's business,
operating results and financial condition.
 
     There can be no assurance that ScanSoft will be able to compete
successfully against current and future competitors, especially those with
greater financial, marketing, recruiting, technical and other resources, or that
competitive pressures will not materially adversely affect ScanSoft's business,
operating results and financial condition.
 
MARKETING, SALES AND DISTRIBUTION
 
     ScanSoft derives the majority of its revenues from sales through its
independent distributors and resellers. Although ScanSoft has established
strategic software OEM partnerships, ScanSoft expects that sales through its
independent distributors and resellers will continue to account for a
substantial portion of its revenues for the foreseeable future.
 
     Domestically, ScanSoft markets its software products through distributors,
including Ingram Micro, Merisel, and Tech Data; computer superstores, such as
CompUSA and Fry's Electronics; consumer electronic stores, such as Best Buy and
Circuit City; mail order houses, such as PC Connection, MicroWarehouse, and
Computer Discount Warehouse; and office superstores, such as OfficeMax, Office
Depot and Staples. Tech Data represented 13%, 11% and 13% of total revenues and
Ingram Micro represented 31%, 35% and 43% of total revenues in 1996, 1997 and
for the nine months ended September 30, 1998, respectively. Accordingly,
ScanSoft will be dependent upon the continued reliability and financial
stability of such distributors and resellers, which are not under the control of
ScanSoft.
 
     Internationally, ScanSoft's products are sold primarily through
distributors and major retailers. As of November 30, 1998, ScanSoft has
distributors servicing Western European, Canada, Australia, New Zealand, Brazil,
Chile, Argentina, South Africa, Taiwan and Japan. European revenues in 1996 and
1997 represented 27% and 21% of total revenues in the respective periods.
European revenue represented 19% of total revenues for the nine months ended
September 30, 1998. ScanSoft's international revenues are subject to certain
risks,
 
                                       60
<PAGE>   67
 
such as currency fluctuations, export controls, import restrictions, longer
payment cycles, greater difficulties in accounts receivable collections and the
requirement of complying with a wide variety of foreign laws. Although ScanSoft
has not previously experienced any difficulties in exporting its products to
other countries, there can be no assurance that ScanSoft will not experience
such difficulties in the future. Any such difficulties would have a material
adverse effect on ScanSoft's international sales. ScanSoft is not currently
affected adversely by export controls or regulations and is not aware of pending
changes in export regulations that would adversely affect its international
business or its ability to collect foreign receivables. See "Risk
Factors -- Risk Factors Related to the Companies' Businesses and
Operations -- International Sales Risks."
 
     ScanSoft's agreements with its distributors generally provide for a limited
right of return, with the distributors receiving full credit of the product's
purchase price, less any discounts, against a purchase order of equal or greater
value. In addition, ScanSoft offers various end user rebate programs for its
products. ScanSoft accrues for expected returns, anticipated price reductions,
and anticipated rebate redemption in amounts that ScanSoft believes are
reasonable. However, there can be no assurance that these accruals will be
sufficient or that any future returns, price protection charges, or rebate
redemption will not have a material adverse effect on ScanSoft's business and
operating results.
 
     As of November 30, 1998, ScanSoft had approximately 44 full time employees
in sales, marketing and support. Domestically, full-featured software product
customers who register with ScanSoft currently receive limited hotline technical
support and product information at no cost. Additional technical support
services are available on a "fee for support" basis. ScanSoft currently offers
several technical support options to customers of packaged products. These
include telephone, fax or e-mail support by a customer support representative or
self-help by accessing ScanSoft's technical information bulletins or frequently
asked questions on the Internet. Outside of the U.S., full-featured software
product customers receive technical support from a third party company on both a
fee and non-fee basis.
 
     ScanSoft has established several strategic OEM relationships in order to
promote its Pagis and TextBridge brand names, expand the number of ScanSoft
registered users and upgrade customers to new or more fully-featured software.
This bundling strategy increased direct revenue, as a percentage of all revenue,
from 2% in 1997 to 13% for the nine months ended September 30, 1998. The success
of this strategy will depend upon a decision by a significant proportion of
customers who first receive software in a bundled form to upgrade with software
from ScanSoft. There can be no assurance that ScanSoft's upgrade strategy will
be successful. ScanSoft is pursuing, and may enter into additional OEM
agreements, with personal computer device manufacturers and software vendors, to
distribute ScanSoft's software products.
 
RESEARCH AND DEVELOPMENT
 
     As of November 1998, there were 53 full time employees on ScanSoft's
research and development staff. ScanSoft's research and development expenditures
in 1996 and 1997 were $4.0 and $5.1 million, respectively, and represented 33%
and 29% of net revenues in the respective periods. Research and development
expenses were $4.5 million and represented 29% of net revenues for the nine
months ended September 30, 1998.
 
     ScanSoft's growth and future financial performance will depend in part upon
its ability to enhance existing applications, develop and introduce new
applications that keep pace with technological advances, meet changing customer
requirements, respond to competitive products and achieve market acceptance. As
a result, ScanSoft expects that it will continue to commit substantial resources
to product development in the future.
 
     ScanSoft works closely with its customers and market research firms to
determine product requirements and to design enhancements and new products to
meet customer needs. ScanSoft's current development initiatives include feature
and function enhancements of existing products, the development of new
complementary products and the development of integrated packages of its
products tailored to the requirements of certain market segments. ScanSoft plans
to enhance its current product line, including new Internet/Intranet
capabilities, as well as support for additional stand-alone and network
connected scanning and image capture devices. There can be no assurance,
however, that such enhancements will result in increased sales or market

the Companies' Business and Operations -- Dependence on Developing Market; Rapid
Technological Change."
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
     ScanSoft relies primarily on a combination of copyright and trademark laws,
trade secrets, confidentiality procedures and contractual provisions to protect
its proprietary rights. ScanSoft seeks to protect its software, documentation
and other written materials under trade secret and copyright laws, which afford
only limited protection. ScanSoft has one image processing patent and three
patent applications pertaining to image processing technology. The patent
applications are still pending. There can be no assurance that any patent
covering ScanSoft's inventions will issue or that any patent, if issued, will
provide sufficiently broad protection or will prove enforceable in actions
against alleged infringers. Despite precautions taken by ScanSoft, it may be
possible for unauthorized third parties, to copy aspects of its products or
future products or to obtain and use information that ScanSoft regards as
proprietary. In particular, ScanSoft provides its licensees with access to its
data model and other proprietary information underlying its licensed
applications. ScanSoft makes source code available for certain of its products
and occasionally enters into source code escrow agreements with certain
customers for the balance of the source code. There can be no assurance that
ScanSoft's means of protecting its proprietary rights will be adequate or that
ScanSoft's competitors will not independently develop similar or superior
technology or design around any patents owned by ScanSoft. Litigation may be
necessary in the future to enforce ScanSoft's intellectual property rights, to
protect ScanSoft's trade secrets or to determine the validity and scope of the
proprietary rights of others. Such litigation could result in substantial costs
and diversion of resources and could have a material adverse effect on
ScanSoft's business, operating results and financial condition.
 
     As a part of the merger agreement, ScanSoft has entered into a license
agreement with Xerox which includes limited licenses and the assignment of
certain patents and trademarks. For a more complete description of the license
agreement, see "Information Regarding Sole Stockholder of ScanSoft -- License
Agreement."
 
     Policing unauthorized use of ScanSoft's products is difficult and, while
ScanSoft is unable to determine the extent to which piracy of its software
products exists, software piracy can be expected to be a persistent problem. In
addition, the laws of some foreign countries do not protect ScanSoft's
proprietary rights to the same extent as do the laws of the United States.
ScanSoft is not aware that any of its product offerings infringe the proprietary
rights of third parties. There can be no assurance however, that third parties
will not claim infringement by ScanSoft with respect to current or future
products. ScanSoft expects that software product developers will increasingly be
subject to infringement claims as the number of products and competitors in
ScanSoft's industry segment grows and the functionality of products in different
industry segments overlaps. Any such claims, with or without merit, could be
time-consuming, result in costly litigation, cause product shipment delays or
require ScanSoft to enter into royalty or licensing agreements. Such royalty or
licensing agreements, if required, may not be available on terms acceptable to
ScanSoft or at all, which could have a material adverse effect on ScanSoft's
business, operating results and financial condition.
 
     ScanSoft also relies on certain technology which it licenses from third
parties. Because ScanSoft's products incorporate software developed and
maintained by third parties, ScanSoft is, to a certain extent, dependent upon
such third parties' ability to maintain or enhance their current products, to
develop new products on a timely and cost-effective basis, and to respond to
emerging industry standards and other technological changes. In the event that
ScanSoft's agreements with its third-party vendors should fail to be renewed or
the products licensed from such vendors should fail to address the requirements
of ScanSoft's software products, ScanSoft would be required to find alternative
software products or technologies of equal performance or functionality. There
can be no assurance that ScanSoft would be able to replace such functionality
provided by the third party software currently licensed by ScanSoft in the event
that such software becomes obsolete or incompatible with future versions of
ScanSoft products or is otherwise not adequately maintained or updated. The
absence of or any significant delay in the replacement of that functionality
could have a material adverse effect on ScanSoft's business, operating results
and financial condition.

REVENUE
 
     ScanSoft's revenues are derived primarily from the sale of shrink-wrapped
software applications sold through the retail channel, direct sales of upgrade
products to its registered users base, and OEM partnerships with scanner and
multifunction device manufacturers. ScanSoft's net revenues increased from
$12,041,000 in fiscal 1996 to $17,790,000 in fiscal 1997 representing an
increase of approximately 48%. Net revenues for the nine month period ended
September 30, 1998 were $15,448,000. ScanSoft believes the increase from fiscal
1996 to 1997 was attributable to overall growth in the imaging device market
coupled with a full year of sales after its entry into the personal document
management market segment in November 1996.
 
     Channel revenues increased from $6,705,000 in fiscal 1996 to $9,051,000 in
fiscal 1997 representing an increase of approximately 35%. Channel revenues
accounted for 56% and 51% of net revenues for fiscal 1996 and 1997,
respectively. Channel revenues for the nine month period ended September 30,
1998 were $8,498,000, increasing to 55% of net revenues. ScanSoft attributes the
growth to an expansion in the number of retail outlets selling its products in
North America, and the overall unit growth in the sale of scanners. Scanner
growth was fueled by significantly lower prices in 1997.
 
     Direct revenues increased from $300,000 in fiscal 1997 to $2,060,000 in the
nine month period ended September 30, 1998. Direct revenues, as a percent of net
revenues, increased from 2% in fiscal 1997 to 13% in
 
                                       64
<PAGE>   71
 
the nine month period ended September 30, 1998. ScanSoft attributes this growth
to direct marketing activity of its growing registered customer database.
 
     OEM revenue increased from $5,336,000 in fiscal 1996 to $8,439,000 in
fiscal 1997, representing an increase of approximately 58%. The increase was due
to higher unit sales by ScanSoft's OEM partners. In addition, the growth was
aided by the first bundling arrangements for Pagis. OEM revenues for the nine
month period ended September 30, 1998 were $4,890,000. OEM revenues, as a
percent of net revenues, decreased from 44% in fiscal 1996 to 47% in fiscal 1997
and 32% for the nine month period ended September 30, 1998 due to higher growth
in North American channel sales and lower unit prices in OEM products.
 
     European revenues totaled approximately $3,268,000 and $3,727,000 in fiscal
years 1996 and 1997, respectively, accounting for approximately 27% and 21% of
net revenues, respectively, due to higher growth in North American channel
sales. European revenues in the nine month period ended September 30, 1998 were
approximately $2,946,000 and 19% of net revenues.
 
COST OF REVENUES
 
     Cost of revenues consists primarily of material costs, third party
royalties, amortization of capitalized software costs, fulfillment, and salaries
for product support personnel. ScanSoft offers "no-fee" product support for
registered customers during the warranty period. Product support costs were
$908,000, $1,141,000 and $984,000 for the fiscal years ended 1996, 1997 and the
nine month period ended September 30, 1998, respectively. As a percent of
revenue, product support costs represented 8% in fiscal 1996 and 6% in both
fiscal 1997 and the nine month period ended September 30, 1998. In accordance
with Financial Accounting Standards No. 86, ScanSoft amortized capitalized
software costs of $317,000, $311,000 and $480,000 in fiscal 1996, 1997 and the
nine month period ended September 30, 1998, respectively. Cost of revenues were
approximately $3,466,000 and $4,430,000 for each of the fiscal years ended
December 31, 1996 and 1997, respectively, representing 29% and 25% of net
revenues for each of the fiscal years ended 1996 and 1997, respectively. Cost of
revenues were approximately $4,466,000 representing 29% of net revenues for the
nine month period ended September 30, 1998. The increase in cost of revenues as
a percent of net revenues from 1997 to 1998 is based on those costs associated
with lower prices per unit.
 
OPERATING EXPENSES
 
     Overall expenses were higher for fiscal 1997 than fiscal 1996 primarily due
to increased marketing and sales costs in support of the increased channel and
direct revenues and higher product development.
 
     Sales and marketing expenses include salaries, commissions, advertising,
direct mail, public relations, trade shows, travel, and other sales and
marketing expenses. Sales and marketing expenses increased from $6,843,000 to
$8,766,000 for fiscal 1996 and fiscal 1997, respectively, representing 57% and
49% of net revenues for each year, respectively. Sales and marketing expenses
for the nine month period ended September 30, 1998 were $6,383,000 representing
41% of net revenues. The increase in sales and marketing was primarily
attributable to higher marketing costs in support of the channel, including
advertising and special promotional opportunities. The decrease in sales and
marketing expenses as a percentage of net revenues from fiscal 1996 to the nine
month period ended September 30, 1998 was principally due to the increased
effectiveness of advertising and other marketing programs and greater acceptance
of ScanSoft's products.
 
     Research and development ("R&D") expenses relate primarily to salary and
benefit costs of engineers. R&D expenses increased from $4,028,000 to $5,129,000
for fiscal 1996 and fiscal 1997, respectively, representing 33% and 29% of net
revenues for each year. R&D expenses for the nine month period ended September
30, 1998 were $4,499,000, representing 29% of net revenues. This decrease in R&D
expenses as a percentage of net revenues in 1997 compared to 1996 was
principally due to the growth of revenue and moderate additions to R&D
personnel. ScanSoft intends to continue to enhance its current products, as well
as develop new technologies for the future, and as such, expects that R&D will
continue to be a significant expense for ScanSoft. In accordance with Statement
of Financial Accounting Standards No. 86, ScanSoft
 
                                       65
<PAGE>   72
 
capitalized $512,000 of software development costs in fiscal 1996, compared to
$424,000 in fiscal 1997. For the nine month period ended September 30, 1998,
ScanSoft capitalized $422,000 of software development costs.
 
     General and administrative expenses include personnel costs for
administration, finance, human resources, and general management in addition to
legal and accounting expenses and other professional services. General and
administrative expenses decreased from $1,488,000 to $1,342,000 for fiscal 1996
and fiscal 1997, respectively. General and administrative expenses as a percent
of net revenues decreased from 12% in fiscal 1996 to 8% in fiscal 1997. General
and administrative expenses for the nine month period ended September 30, 1998
were $1,919,000, representing an increase to 12% of net revenues. The increase
was due in part to a $225,000 reserve for bad debt needed as a result of a
customer's recent bankruptcy filing, as well as an increase in audit fees
associated with the merger.
 
CERTAIN TRENDS
 
     ScanSoft's results in the future may be affected by factors over which it
has very little control. These include, but are not limited to, adverse changes
in the economic conditions in the United States and in international markets in
which it participates. In addition the computer software markets in which
ScanSoft participates are characterized by rapid change in technology. ScanSoft
may be affected by the development of new or improved technology by its existing
competitors (some of whom have greater financial resources) or new entrants
drawn to the market due to the overall increase in the unit volumes of scanners,
multifunction devices and digital cameras. ScanSoft may also be affected by the
actions of the scanner and multifunction manufacturers themselves. Scanner
prices have dropped significantly over the last 24 months. This has lead to
lower per unit revenue to ScanSoft from its OEM partners. In addition, it has
lead to some instability in the financial condition of several key scanner
manufacturers. The recent bankruptcy of one of ScanSoft's key OEMs is an example
of the impact that the lower pricing is having in the marketplace. There can be
no assurance that other ScanSoft OEMs would not also be so affected.
 
     In late 1997 ScanSoft upgraded most of its OEMs with bundled software that
encouraged electronic and/or Internet registration. This has led to an increase
in registered customers from 176,000 at December 31, 1997 to 427,000 at
September 30, 1998. ScanSoft plans to increase its direct and Internet marketing
activities to these customers and expects a higher percentage of its revenue to
come from direct upgrade activity in the future. There can be no assurance that
the combined companies will be able to maintain these relationships with these
OEMs or that registered customers will continue to upgrade.
 
     A significant portion of ScanSoft's net revenues is attributable to sales
through the distribution channel. ScanSoft's future operating results are
dependent on maintaining these relationships. There can be no assurance that the
combined company will be able to do so.
 
YEAR 2000 COMPLIANCE
 
     ScanSoft is in the process of assessing the potential effects of the "Year
2000" millennium change on its business systems and processes, including
facilities, software and components used by its employees, as well as its
outsourcing vendors and critical suppliers. ScanSoft's Year 2000 project is
proceeding on schedule. The project goal is to ensure that ScanSoft's business
is not impacted by the date transitions associated with the Year 2000.
 
     ScanSoft's Year 2000 project plan is coordinated by a team that reports to
senior management. The project team is evaluating the Year 2000 compliance of
ScanSoft's business systems and processes, including facilities, software and
components used by its employees, as well as its outsourcing vendors and
critical suppliers whom provide services relating to its business. ScanSoft's
Year 2000 project is comprised of the following phases:
 
     - Phase 1 -- Inventory all business systems and processes, including
       facilities, software and components used by ScanSoft's employees, in
       order to assign priorities to potentially impacted systems and services.
       This phase was completed by December 31, 1998.
 
                                       66
<PAGE>   73
 
     - Phase 2 -- Assess the Year 2000 compliance of all inventoried business
       systems and processes, including facilities, software and components used
       by ScanSoft's employees, and determine whether to renovate or replace any
       non-Year 2000 compliant systems and services. ScanSoft expects to
       complete this phase by March 31, 1999.
 
     - Phase 3 -- Complete replacement or renovation, if required, of any
       non-compliant business systems and processes, including facilities,
       software and components used by ScanSoft's employees and ScanSoft's
       outsourcing vendors. Conduct procurements to replace any other non-Year
       2000 compliant business systems and processes, including facilities,
       software and components used by ScanSoft's employees and ScanSoft's
       outsourcing vendors that will not be remediated. Test and validate
       remedied and replacements systems, if any such remediation or replacement
       is required, to ensure inter-system compliance and mission critical
       system functionality. ScanSoft expects to complete testing, remediation
       and validation efforts, if any are required, by June 30, 1999.
 
     - Phase 4 -- Deploy and implement remedied and replacement systems, if any
       deployment or implementation is required, after the completion of
       successful testing and validation. ScanSoft expects to complete the
       deployment and implementation of the remedied or replacement systems, if
       required, by September 30, 1999.
 
     - Phase 5 -- Design contingency plan and business continuation plans in the
       event of the failure of business systems and processes, facilities, data
       networking infrastructure, software and components used by ScanSoft's
       employees due to the Year 2000 millennium change. ScanSoft expects that
       the initial contingency and business continuation plan will be in place
       by November 30, 1999.
 
     Based on ScanSoft's inventory and assessment to date, it believes that its
facilities can be Year 2000 compliant. In addition, it is seeking assurances
from its facilities' landlords and equipment vendors and data circuit providers
regarding the Year 2000 compliance of their facilities and equipment.
 
     At this time, ScanSoft believes that its incremental remediation costs
needed to make its current business systems and processes, including facilities,
software and components used by its employees and its outsourcing vendors are
not material. While ScanSoft is incurring some incremental costs, its costs
through September 30, 1998 were less than $40,000. ScanSoft's expected total
costs, including remediation and replacements costs, if any, are estimated to be
between $50,000 and $75,000 over the life of the Year 2000 project.
 
     ScanSoft is contacting its hardware and software vendors, other significant
suppliers, manufacturers, outsourcing service providers and other contracting
parties to determine the extent to which it is vulnerable to any one of their
failures to achieve Year 2000 compliance for their own systems. At the present
time, ScanSoft does not expect Year 2000 issues of any such third parties to
materially affect its business.
 
     Should ScanSoft fail to solve a Year 2000 compliance problem critical to
its business systems and processes, the result could be a failure or
interruption to normal business operations. The reasonably likely worst case
risks inherent in ScanSoft's business are as follows:
 
     - Despite the assurances of ScanSoft's third-party suppliers, hardware and
       software vendors and outsourcing service providers regarding the Year
       2000 compliance of their products and services, the potential exists that
       a Year 2000 problem relating to such third-party suppliers, vendors and
       outsourcing service providers products and services could have a material
       impact on ScanSoft's business. ScanSoft is conducting monthly discussions
       with its critical outsourcing service providers to determine the progress
       of their Year 2000 compliance programs.
 
     - Despite extensive preparation and effort to ensure Year 2000 compliance,
       implementation of its business continuation contingency plan for a very
       short time may be required while ScanSoft remediates the Year 2000
       problem.
 
     Despite its belief that its mission critical computer software applications
and systems are Year 2000 compliant and its expectation that its enhancement
effort will result in Year 2000 compliant systems, ScanSoft is currently
developing a business continuation contingency plan. ScanSoft expects to
finalize its initial contingency plan to complete the testing all existing
systems by November 30, 1999.

  Forward-Looking Statements
 
     The foregoing Year 2000 discussion contains "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995. Such
statements, including without limitation, anticipated costs and the dates by
which certain actions are expected to be completed, are based on management's
best current estimates, which were derived utilizing numerous assumptions about
future events, including the continued availability of certain resources,
representations received from third parties and other factors. However, there
can be no guarantee that these estimates will be achieved, and actual results
could differ materially from those anticipated. Specific factors that might
cause such material differences include, but are not limited to, the ability to
identify and remediate all relevant systems, results of Year 2000 testing,
adequate resolution of Year 2000 issues by governmental agencies, businesses and
other third parties who are outsourcing service providers suppliers, and
vendors, unanticipated system costs, the adequacy of and ability to implement
contingency plans and similar uncertainties. The "forward-looking statements"
made in the foregoing Year 2000 discussion speak only as of the date on which
such statements are made, and management does not undertake any obligation to
update any forward-looking statement to reflect events or circumstances after
the date on which such statement is made or to reflect the occurrence of
unanticipated events.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     ScanSoft's operating activities used cash of $2,763,000 and $3,576,000 in
fiscal years 1996 and 1997, respectively. ScanSoft generated cash from
operations of $487,000 in the nine month period ended September 30, 1998.
ScanSoft maintains a "zero balance account" with Xerox for operating activities
in the United States. All cash transactions, deposits and disbursements are
recorded in an intercompany account with Xerox, which has been reflected in
ScanSoft's financial statements and notes. Disbursements in excess of deposits
are funded by Xerox, free of interest charges. Cash received in excess of
disbursements reduce the intercompany account with Xerox. ScanSoft used cash
from investing activities of ($1,110), ($1,426) and ($701) for the years ended
December 31, 1996 and 1997 and for the nine months ended September 30, 1998,
respectively, related to purchases of property and equipment and the
capitalization of software development costs. Cash provided by net transactions
with Xerox amounted to $5,196, $4,067 and $851 for the years ended December 31,
1996 and 1997 and for the nine months ended September 30, 1998, respectively.
 
     ScanSoft offers credit terms to qualifying customers and also sells on a
prepaid and credit card basis. With respect to credit sales, ScanSoft attempts
to control its bad debt exposure through monitoring of customer's
creditworthiness. With the exception of the recent bankruptcy filing of a
customer, ScanSoft has not experienced any significant write-offs of bad debts.
 
     ScanSoft has financed its operations to date through funds made available
by Xerox. There can be no assurance that such funds will be made available to
ScanSoft after consummation of the proposed transaction with Visioneer.

                        COMPARISON OF STOCKHOLDER RIGHTS
 
GENERAL
 
     The rights of Visioneer stockholders are currently governed by Delaware law
and the certificate of incorporation and bylaws of Visioneer. The rights of
ScanSoft stockholders are currently governed by Delaware law and the certificate
of incorporation and bylaws of ScanSoft. Upon consummation of the merger, the
rights of stockholders of the Surviving Corporation will be governed by Delaware
law, the Visioneer certificate of incorporation as it is amended, and the
Visioneer bylaws. The following is a summary of the principal differences
between the current rights of ScanSoft stockholders and those of Visioneer
stockholders following the merger.
 
     The following summary is not intended to be complete and is qualified in
its entirety by reference to Delaware law, the Visioneer certificate of
incorporation and bylaws, and the ScanSoft certificate of incorporation and
bylaws. The Visioneer certificate of incorporation and bylaws are incorporated
by reference herein. Any of these documents will be sent to stockholders upon
request. See "Where You Can Find More Information" on page 1.
 
COMPARISON OF CURRENT SCANSOFT STOCKHOLDER RIGHTS AND RIGHTS OF STOCKHOLDERS
FOLLOWING THE MERGER
 
     The Visioneer certificate of incorporation will be amended in connection
with the merger as set forth in Annex E and as discussed in "Description of
Capital Stock." The rights of Visioneer stockholders after the merger will be
the same as their rights prior to the merger.
 
     The rights of ScanSoft stockholders under Delaware law and the ScanSoft
certificate of incorporation and bylaws prior to the merger will be
substantially the same as the rights of stockholders under Delaware law and the
Surviving Corporation's certificate of incorporation and bylaws, with the
following principal exceptions.
 
  Authorized Capital Stock
 
     The authorized capital stock of ScanSoft consists of 27,000,000 shares of
common stock and 23,000,000 shares of preferred stock, par value $0.001 per
share (of which 16,000,000 shares are designated Series A participating
preferred stock (the "ScanSoft Series A Preferred Stock")). The authorized
capital stock of Visioneer is set forth under "Description of Capital
Stock -- Existing Capital Stock."
 
  Board of Directors
 
     The ScanSoft bylaws provide that the number of directors shall be
determined by resolution of a majority of the ScanSoft board. ScanSoft currently
has one director. The ScanSoft certificate of incorporation does not provide for
cumulative voting for the election of directors.
 
     Vacancies in the ScanSoft board may be filled by resolution of a majority
of the ScanSoft board (or a sole director, if applicable) or by the stockholders
at an annual meeting or special meeting called for that purpose, and any
director so appointed will hold office until the next annual election of
directors of that class. The ScanSoft bylaws provide that the directors may be
removed from office, but only for cause, by vote of the holders of a majority of
shares entitled to vote for the election of directors.
 
     The Visioneer bylaws provide that the number of directors shall be
determined by resolution of a majority of Visioneer's board of directors.
Visioneer currently has five directors. Under the Visioneer bylaws, Visioneer
directors are elected at the annual meeting of stockholders and each director
elected holds office until his/her successor is elected and qualified, unless
he/she shall resign, become disqualified, disabled or otherwise removed. Neither
the Visioneer certificate of incorporation nor the Visioneer bylaws provide for
cumulative voting for election of directors. Nominations of persons for election
to Visioneer's board of directors may be made by or at the direction of
Visioneer's board of directors, or by Visioneer stockholders according to the
procedures described in the Visioneer bylaws. Under the Visioneer bylaws,
vacancies in Visioneer's board of directors may be filled by resolution of a
majority of Visioneer's board of directors (or a sole director, if applicable),
and any director so appointed will hold office until the next annual meeting of
stockholders. The
 
                                       69
<PAGE>   76
 
bylaws provide that directors may be removed (with or without cause) by vote of
the holders of a majority of shares entitled to vote at an election of
directors.
 
     In connection with the merger, Xerox and certain affiliates of Visioneer
holding approximately 29% of Visioneer's voting stock as of the date of this
proxy statement/prospectus (the "Investors") have agreed to enter into a voting
agreement pursuant to which, among other things, they will vote to elect certain
nominees to the Surviving Corporation's board of directors. Xerox and the
Investors have agreed that as of the effective time of the merger, Visioneer's
bylaws will be amended to provide for a seven member board, and that two
nominees of Xerox as well as the Chief Executive Officer of the Surviving
Corporation will be elected to the board as of the first board meeting
thereafter. The voting agreement also provides that in any election of board
members, the parties to the voting agreement will vote their shares so as to
elect certain designees and describes the manner in which such designees will be
determined. See "The Merger Agreement and Related Agreements."
 
  Action Without a Meeting
 
     The Visioneer certificate of incorporation provides that no action required
to be taken or that may be taken at any annual or special meeting of the
stockholders may be taken without a meeting and that the power of the
stockholders to consent in writing, without a meeting, to the taking of any
action is specifically denied.
 
  Special Meetings of Stockholder
 
     The ScanSoft bylaws provide that special meetings of stockholders may be
called by the chairman, president, board of directors or the holders of not less
than 10% of all shares entitled to vote at the meeting. The Visioneer bylaws
provide that special meetings of stockholders may be called by the president and
shall be called by the president or secretary at the written request of a
majority of Visioneer's board of directors, or at the request in writing of
stockholders owning not less than 10% of the entire capital stock of the
corporation issued and outstanding and entitled to vote.
 
  Amendment of Certificate of Incorporation and Bylaws
 
     Both the Visioneer and ScanSoft certificates of incorporation reserve the
right of each company to amend, alter or change any provision contained in such
certificate of incorporation, in accordance with Delaware law. Pursuant to
Delaware law, amendment of a company's certificate of incorporation requires the
approval of a majority of the board of directors and the approval of the holders
of a majority of the outstanding capital stock. The ScanSoft certificate of
incorporation further provides that the affirmative vote of the majority of the
outstanding shares of ScanSoft Series A Preferred Stock is required for any
amendment to the ScanSoft certificate of incorporation that would materially
adversely affect the powers, preferences or special rights of such preferred
stockholders.
 
  Voting Rights
 
     Each outstanding share of ScanSoft common stock is entitled to one vote on
all matters submitted to ScanSoft stockholders. Each holder of ScanSoft Series A
Preferred Stock has full voting rights and powers equal to the voting rights and
powers of the holders of ScanSoft common stock and each outstanding share of
ScanSoft Series A Preferred Stock is entitled to one vote on all matters
submitted to ScanSoft stockholders.
 
     The outstanding voting securities of Visioneer are the shares of Visioneer
common stock. Under Delaware law, each share of Visioneer common stock is
entitled to one vote on all matters submitted to Visioneer stockholders.
 
  Removal of Officers
 
     The ScanSoft bylaws permit the removal of any officer by the ScanSoft board
with or without cause. The Visioneer bylaws permit Visioneer's board of
directors to remove any officer elected by the board at any time by the
affirmative vote of a majority of Visioneer's board of directors.
 
                                       70
<PAGE>   77
 
  Rights Plan
 
     Visioneer has entered into a Rights Agreement (as amended, the "Rights
Agreement"), with U.S. Stock Transfer Corporation N.A. as rights agent. Pursuant
to the Rights Agreement, rights attach to each share of Visioneer common stock
outstanding and entitle the registered holder to purchase from Visioneer a
fraction of a share of Series A Preferred Stock at a purchase price of $27.50
(the "Purchase Price"), subject to adjustment. Each share of Visioneer common
stock outstanding has one right attached.
 
     The rights will separate from the Visioneer common stock upon the earlier
of (A) 10 days following a public announcement that a person or group of
affiliated or associated persons (an "Acquiring Person") has acquired or
obtained the right to acquire beneficial ownership of 20% or more of the
outstanding shares of Visioneer common stock (the "Stock Acquisition Date") or
(B) 10 business days following the commencement of a tender offer or exchange
offer that would result in a person or group beneficially owning 20% or more of
such outstanding shares of Visioneer common stock, unless a later date is fixed
by Visioneer's board of directors (the date of any such event, the "Distribution
Date"). Until the Distribution Date, the rights will be evidenced by Visioneer
common stock certificates and will be transferred with and only with Visioneer
common stock certificates. New Visioneer common stock certificates will contain
a notation incorporating the Rights Agreement by reference and the transfer of
any certificates representing outstanding Visioneer common stock outstanding
will also constitute the transfer of the associated rights.
 
     In the event that an Acquiring Person becomes the beneficial owner of 20%
or more of the then outstanding shares of Visioneer common stock in an
acquisition which has not met certain requirements, each holder of a right
(other than the Acquiring Person) will thereafter have the right to receive upon
exercise Visioneer common stock having a value twice the exercise price of the
right.
 
     If, following a Stock Acquisition Date, Visioneer engages in a merger or
business combination transaction in which Visioneer is not the surviving
corporation (other than a transaction which has met certain requirements) each
holder of the right will thereafter have the right to receive, upon exercise of
the right, common stock of the acquiring party having a value twice the exercise
price of the right.
 
     The rights are not exercisable until the Distribution Date and will expire
at the close of business on October 23, 2006, unless earlier redeemed by
Visioneer as further described in the Rights Plan. At no time will the holder of
the rights as such have any voting power or any rights as a stockholder. Subject
to certain exceptions, any of the provisions of the Rights Agreement may be
amended by Visioneer's board of directors prior to the Distribution Date.
 
     Pursuant to the merger agreement, Visioneer has amended the Rights Plan
such that neither ScanSoft nor any of its Affiliates (as defined therein) shall
become an Acquiring Person, nor shall any Distribution Date or Shares
Acquisition Date occur, if ScanSoft or any of its Affiliates becomes a
beneficial owner of Visioneer common stock pursuant to and not in contravention
of the merger agreement and the transactions contemplated by the merger
agreement.
 
     The above summary of the Rights Agreement does not purport to be complete
and is qualified in its entirety by reference to the terms and conditions of the
Rights Agreement. See "Where You Can Find More Information" on page 1.
 
     ScanSoft does not have a Rights Plan.

                          DESCRIPTION OF CAPITAL STOCK
 
EXISTING CAPITAL STOCK
 
     Visioneer is authorized by its existing certificate of incorporation to
issue an aggregate of 50,000,000 shares of common stock, par value $0.001 per
share and 5,000,000 shares of preferred stock, par value $0.001 per share. As of
the record date, there were 19,852,952 shares of common stock outstanding that
were held of record by approximately 265 stockholders. The following is a
summary of certain of the rights, powers, preferences and limitations pertaining
to Visioneer's capital stock. For a full description of the common stock and
preferred stock, you should refer to the amended and restated certificate of
incorporation and the bylaws of Visioneer as currently in effect, copies of
which are on file with the Securities and Exchange Commission.
 
  Common Stock
 
     Holders of common stock are entitled to one vote per share on all matters
submitted to a vote of stockholders. Approval of matters brought before the
stockholders requires the affirmative vote of a majority of outstanding shares,
except as otherwise required by law. Subject to the rights of holders of
preferred stock, if any, all shares of common stock are entitled to share in
such dividends as the board of directors may from time to time declare from
sources legally available therefor. Subject to the rights of creditors and
holders of preferred stock, if any, holders of common stock are entitled to
share ratably in a distribution of assets of Visioneer upon any liquidation,
dissolution or winding-up of Visioneer.
 
  Existing Preferred Stock
 
     The board of directors of Visioneer is authorized to issue, by resolution
and without any action by stockholders, up to 5,000,000 shares of preferred
stock and may establish the voting rights, designations, preferences and
relative, participating, optional or other special rights of such series of
preferred stock.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF THE EXISTING CERTIFICATE OF INCORPORATION
AND DELAWARE LAW
 
  Certificate of Incorporation
 
     Under Visioneer's existing certificate of incorporation, the board of
directors has the power to authorize the issuance of up to 5,000,000 shares of
preferred stock and to determine the price, rights, preferences, privileges and
restrictions, including voting rights, of those shares without further vote or
action by the stockholders. The issuance of preferred stock, while providing
desirable flexibility in connection with possible acquisitions and other
corporate purposes, may have the effect of delaying, deferring or preventing a
change in control of Visioneer, may discourage bids for the common stock at a
premium over the market price of the common stock and may adversely affect the
market price of and the voting and other rights of the holders of the common
stock.
 
  Delaware Takeover Statute
 
     Visioneer is subject to section 203 of Delaware General Corporation Law,
which, subject to certain exceptions, prohibits a Delaware corporation from
engaging in any business combination with any interested stockholder for a
period of three years following the date that such stockholder became an
interested stockholder, unless: (i) prior to such date, the board of directors
of the corporation approved either the business combination or the transaction
that resulted in the stockholder becoming an interested stockholder; (ii) upon
consummation of the transaction that resulted in the stockholder becoming an
interested stockholder, the interested stockholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced, excluding for purposes of determining the number of shares
outstanding those shares owned (x) by persons who are directors and also
officers and (y) by employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
law will be tendered in a tender or exchange offer; or (iii) on or subsequent to
such date, the
 
                                       72
<PAGE>   79
 
business combination is approved by the board of directors and authorized at an
annual or special meeting of stockholders, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock that is not
owned by the interested stockholder.
 
     Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, lease, exchange, mortgage, pledge, transfer or other disposition of (in
one transaction or a series of transactions) 10% or more of the assets of the
corporation involving the interested stockholder; (iii) subject to certain
exceptions, any transaction that results in the issuance or transfer by the
corporation, or by any direct or indirect majority-owned subsidiary thereof, of
any stock of the corporation or such subsidiary to the interested stockholder;
(iv) any transaction involving the corporation, or any direct or indirect
majority-owned subsidiary thereof, that has the effect of increasing the
proportionate share of the stock of any class or series of the corporation or
any such subsidiary which is owned by the interested stockholder; or (v) the
receipt by the interested stockholder of the benefit, directly or indirectly, of
any loans, advances, guarantees, pledges or other financial benefits provided by
or through the corporation or any direct or indirect majority-owned subsidiary
thereof. In general, section 203 defines an interested stockholder as any entity
or person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.
 
CAPITAL STOCK FOLLOWING THE MERGER
 
     If the merger is approved by the requisite vote of the stockholders of
Visioneer at the special meeting, the certificate of incorporation of Visioneer
will be amended and restated at the effective time of the merger. The amended
and restated certificate of incorporation, in the form attached as Annex E to
this proxy statement/ prospectus and incorporated herein by reference, will be
that of the Surviving Corporation. The following is a summary of certain of the
rights, powers, preferences and limitations pertaining to the capital stock of
Visioneer after giving effect to the merger. For a full description of such
capital stock, see Annex E hereof.
 
     Pursuant to the proposed amendment and restatement to the certificate of
incorporation, the Surviving Corporation will be authorized to issue 70,000,000
shares of common stock and 20,000,000 shares of preferred stock, of which
15,000,000 shares will be designated as Series B preferred stock.
 
     Holders of common stock will be entitled to one vote per share on all
matters submitted to a vote of stockholders. Approval of matters brought before
the stockholders will require the affirmative vote of a majority of the holders
of the outstanding shares of common stock, except as otherwise required by
Delaware law. In addition, a supermajority vote of the common stock will be
required for certain matters, including:
 
     - the merger or sale of substantially all the assets of the Surviving
       Corporation;
 
     - the authorization or issuance of any equity security having a preference
       over or being on a parity with the Series B preferred stock with respect
       to voting, dividends, conversion or upon liquidation;
 
     - any alteration or change, in an adverse manner, to the rights,
       preferences and privileges of the Series B preferred stock;
 
     - any change in the total number of authorized shares of Series B preferred
       stock;
 
     - subject to certain exceptions, the redemption, purchase or acquisition of
       any shares of common stock or preferred stock;
 
     - the declaration or payment of dividends on the common stock or preferred
       stock; or
 
     - any amendment to the bylaws of the Surviving Corporation.
 
     Following the merger, the board of directors of the Surviving Corporation
will be authorized to issue, from time to time, by resolution and without any
action by stockholders, up to 20,000,000 shares of preferred stock, par value
$0.001 per share, in one or more classes and/or series and may establish the
powers, designations, preferences, rights and qualifications, limitations or
restrictions (which may differ with respect to each such class and/or series) of
such class and/or series. Of these shares, 15,000,000 will be designated Series
B preferred stock. The Series B preferred stock will be convertible into shares
of common stock of the
 
                                       73
<PAGE>   80
 
Surviving Corporation on a share for share basis at the execution of the holder
at any time after the second anniversary of the merger; however, the Series B
preferred stock is convertible immediately if the holder's ownership of
outstanding Surviving Corporation common stock is less than 30%, unless such
conversion results in the holder owning more than 50% of the outstanding
Surviving Corporation common stock.
 
     The Series B preferred stock will be entitled to dividends at the rate of
$0.065 per annum, payable when, as and if declared by the board of directors of
the Surviving Corporation but subject to availability of funds. Dividends will
be non-cumulative. The Series B preferred stock will have a liquidation
preference of $1.30 per share plus all declared but unpaid dividends.
 
     Holders of Series B preferred stock will not have any voting rights, except
for such rights as are provided under Delaware law.
 
     There is currently no other series of preferred stock authorized by
Visioneer's certificate of incorporation or outstanding. However, Visioneer has
authorized the creation of Series A preferred stock which may be issued pursuant
to Visioneer's Rights Plan, and the filing of a certificate of designation
setting forth the rights of the Series A preferred stock.
 
     Certain holders of capital stock are also entitled to certain registration
rights. See "The Merger Agreement and Related Agreements -- Related
Agreements -- Registration Rights Agreements."

                  THE MERGER AGREEMENT AND RELATED AGREEMENTS
 
     The following summary describes the material provisions of the merger
agreement, a copy of which is attached as Annex A to this proxy
statement/prospectus and is incorporated herein by reference. This summary is
qualified in its entirety by reference to the merger agreement.
 
THE MERGER
 
     The merger agreement provides that, following the approval of the merger
and the adoption of the merger agreement by the affirmative vote of the holders
of a majority of the outstanding shares of common stock of Visioneer entitled to
vote thereon, and the satisfaction or waiver of the other conditions to the
merger, ScanSoft will be merged with and into Visioneer, the separate corporate
existence of ScanSoft will cease, and Visioneer will continue as the surviving
corporation succeeding to and assuming all rights and obligations of ScanSoft
and Visioneer in accordance with Delaware law.
 
     If the conditions to the merger are satisfied or waived, a certificate of
merger will be filed with the Secretary of State of Delaware. The merger will
become effective upon the filing and acceptance thereof or at such date
thereafter as ScanSoft and Visioneer have agreed and have specified in the
certificate of merger.
 
     In the merger, each share of Visioneer common stock outstanding at the
effective time (other than shares held by Visioneer, which will be canceled and
retired and shall cease to exist, and any fractional shares and Dissenting
Shares) will be exchanged, based on the election made by each stockholder, for
cash or common stock of the Surviving Corporation, as more fully described under
"The Merger -- Merger Consideration" and "-- Cash Election and Proration for
Visioneer Stockholders." For a discussion of the treatment of fractional shares,
see "The Merger -- Fractional Shares," and for Dissenting Shares, see
"Stockholders' Appraisal Rights."
 
  Book Value Adjustment
 
     The number of shares of Visioneer common stock to be exchanged for cash and
the number of shares of Series B preferred stock to be received by XIS will be
subject to adjustment based upon the variance from a predetermined relationship
between the Visioneer net book value and the ScanSoft net book value, each
calculated on a date prior to the merger. If the difference between the
Visioneer net book value and the ScanSoft net book value is higher than the
predetermined variance, then the cash election number of 5,097,000 shares will
be increased by a number of shares equal to the excess of such variance divided
by $2.06. Such additional shares are referred to as the "Additional Cash
Election Shares." Alternatively, in the event that the difference between the
Visioneer net book value and the ScanSoft net book value is less than the
predetermined variance, then the cash election number of 5,097,000 will not
increase. Instead, Visioneer will issue to XIS that number of additional shares
of Series B preferred stock equal to such shortfall divided by approximately
$2.06.
 
     The purpose of this book value adjustment is to adjust the consideration
amounts to be received and the relative ownership percentages in the Surviving
Corporation that are contemplated by the merger agreement. The book value
adjustment compensates for changes in the value of either Visioneer or ScanSoft
that occur in the time period (which is expected to exceed 90 days) between the
signing of the merger agreement, at which time the deal terms were set, and the
effective time of the merger.

ordinary course in substantially the same manner as currently conducted and to
use all reasonable efforts to preserve intact its business organization, to keep
available the services of its present officers and key employees and to preserve

       the transactions provided for in the merger agreement; or
 
     - authorize, recommend, propose or announce an intention to do any of the
       foregoing.
 
  No Solicitation of Transaction
 
     Pursuant to the merger agreement, each of Visioneer and ScanSoft has agreed
that neither Visioneer nor ScanSoft nor any officer, director, employee,
stockholder, or agent of Visioneer or ScanSoft, will, directly or indirectly,
solicit, initiate, entertain, or encourage any proposals or offers from any
third party relating to an acquisition of their respective company or any
acquisition of a material portion of the assets or stock of their respective
company, whether through a merger, consolidation, stock purchase, purchase of
all or substantially all of its assets, or acquisition of all or substantially
all of its stock or other similar transaction (a "Takeover Proposal") or
participate in any discussions or negotiations regarding any Takeover Proposal,
provided that prior to the receipt of approval of the merger by the Visioneer
stockholders, Visioneer may, together with its officers, directors and financial
advisors, to the extent the Visioneer board of directors determines, in good
faith, after consultation with outside legal counsel, that it would be a breach
of the board's fiduciary duties to fail to do so, participate in discussions or
negotiations with and afford access to the properties, books or records of
Visioneer to any person, entity or group after such person, entity or group has
delivered to Visioneer in writing an unsolicited Superior Proposal (as defined
below) (which Superior Proposal has not been withdrawn).
 
     Neither the board of directors of Visioneer nor any committee thereof may
withdraw or modify, or propose publicly to withdraw or modify, in a manner
adverse to ScanSoft, the approval or recommendation by Visioneer's board of
directors of the merger or the merger agreement. The merger agreement does not
prevent Visioneer, at any time prior to the receipt of stockholder approval of
the merger, from: (A) modifying or withdrawing the recommendation of the board
of directors to approve the merger if the board of directors determines in good
faith that a Takeover Proposal is a Superior Proposal (as defined below) and,
after consultation with outside counsel, that it would be a breach of its
fiduciary responsibilities to not so modify or withdraw such recommendation; or
(B) to approve or recommend, or propose publicly to approve or recommend, such
Superior Proposal if the board of directors of Visioneer determines in good
faith, after consulting with outside counsel, that it would be a breach of its
fiduciary responsibilities to not approve or recommend such Superior Proposal. A
"Superior Proposal" is defined in the merger agreement as any
 
                                       78
<PAGE>   85
 
unsolicited written proposal determined by the Visioneer board of directors in
good faith, after consultation with outside legal counsel, to be a bona fide
proposal and made by a third party to acquire, directly or indirectly, for
consideration consisting of cash, property and/or securities, more than 50% of
the combined voting power of the shares of the Visioneer common stock then
outstanding or all or substantially all the assets of Visioneer and otherwise on
terms which the Visioneer board of directors determines in its good faith
judgment to be more favorable to Visioneer's stockholders than the merger, after
consultation with outside counsel and receipt of a written opinion of a
financial advisor of nationally recognized reputation that the terms of such
written proposal are more favorable from a financial point of view than the
merger.
 
     Visioneer must promptly notify ScanSoft in writing of the terms of any
third party inquiries or proposals involving a Takeover Proposal received by
Visioneer, identify the name of such third party and provide ScanSoft with a
copy of such Superior Proposal prior to taking the above action. Visioneer may
approve or recommend a Superior Proposal or terminate the merger agreement,
subject to the payment of specified termination fees. See "-- Additional
Agreements -- Fees and Expenses" below.
 
  Third Party Standstill Agreements and Rights Agreement
 
     The merger agreement provides that Visioneer will not terminate, amend,
modify or waive any provision of any confidentiality or standstill agreement to
which it is a party (other than any such agreement involving ScanSoft) or,
except for the amendment of the Rights Agreement in connection with the merger,
redeem, amend, modify or waive the rights or any provisions of the Rights
Agreement.
 
  Stock Plans
 
     The treatment in the merger of outstanding Visioneer stock options is
described in "The Merger -- Effect on Visioneer and ScanSoft Options."
 
  Commercially Reasonable Efforts
 
     Pursuant to the merger agreement, Visioneer, and ScanSoft have agreed to
use commercially reasonable efforts to effectuate the transactions contemplated
by the merger agreement and to take certain other actions, including (A)
obtaining from any governmental body any consents, licenses, permits, waivers,
approvals, authorizations or orders required to be obtained or made in
connection with the authorization, execution and delivery of the merger
agreement, including those required under the HSR Act, and (B) make all
necessary filings, and thereafter make any other required submissions, with
respect to the merger agreement and the merger required under the Securities Act
and the Exchange Act and any other applicable federal, state or foreign
securities laws.

agreed to the following additional covenants:
 
  Obligations of both Visioneer and ScanSoft

     - abide by the terms of the confidentiality agreement;
 
     - afford to each other and to the accountants, counsel, and other
       representatives of each party reasonable access to the properties, books,
       contracts, commitments, and records and all other information as may be
       needed;
 
     - not make any public announcements with respect to the merger except as
       required by law;
 
     - give prompt notice to the other of: (A) the occurrence or non-occurrence
       of any event, the occurrence or non-occurrence of which would be
       reasonably likely to cause any representation or warranty contained in
       the merger agreement to be untrue or inaccurate in any material respect,
       and (B) the
 
                                       79

       failure to comply with in any material respect or satisfy in any material
       respect any covenant, condition or agreement related to the merger.
 
  Obligations of Visioneer
 
     Pursuant to the terms of the merger agreement, Visioneer will:
 
     - comply with the securities and blue sky laws of all applicable
       jurisdictions;
 
     - file a notification form to list the shares of common stock to be issued
       in the merger on the Nasdaq National Market; and
 
     - use reasonable efforts to grant the necessary approvals if any "fair
       price" or "control share acquisition" statute or other similar statute or
       regulation shall become applicable to the merger agreement.
 
  Obligations of ScanSoft
 
     Pursuant to the terms of the merger agreement, ScanSoft will:
 
     - use its reasonable efforts to assist Visioneer as may be necessary to
       comply with the applicable securities and blue sky laws;

       Property Tax Act of 1980 ("FIRPTA") Notification Letter;
 
     - provide Visioneer a form of notice to the Internal Revenue Service in
       accordance with the requirements of Treasury Regulation section

  Maintenance of Indemnification Obligations
 
     Pursuant to the merger agreement, the Surviving Corporation will indemnify
and hold harmless each present and former director, officer, employee and agent
of Visioneer determined as of the effective time (the "Indemnified Parties") to
the extent provided in the bylaws or certificate of incorporation of Visioneer
and as provided in any surviving indemnification agreements between Visioneer
and an Indemnified Party. The Surviving Corporation will be obligated to pay
reasonable expenses, including reasonable attorney's fees that may be incurred
by such Indemnified Parties in connection with any claim, action, suit,
proceeding or investigation arising out of or pertaining to matters existing or
occurring at or prior to the effective time. The Surviving Corporation will also
advance any such expenses as incurred to the fullest extent permitted under the
bylaws or certificate of incorporation of Visioneer, subject to the undertaking
of such party to repay such advances in the event that it is ultimately
determined that such party is not entitled to indemnification.
 
     For a period of six years after the effective time, the Surviving
Corporation will maintain a policy of officers' and directors' tail liability
insurance for directors and officers of Visioneer who terminate or resign their
positions after the date of the merger agreement but on or prior to the
effective time. The coverage under such insurance must be at least as favorable
as Visioneer's existing directors' and officers' liability insurance coverage;
however, the Surviving Corporation will not be obligated to pay aggregate
premiums for such tail coverage in excess of $250,000.
 
  Fees and Expenses
 
     Visioneer has agreed to pay ScanSoft by wire transfer a termination fee in
an amount equal to $1,700,000 (1) if the merger agreement is terminated because
the board of directors of Visioneer or any committee thereof fails to recommend,
withdraws, modifies or publicly announces in a manner adverse to ScanSoft, its
approval or recommendation of the merger or the merger agreement or (2) if the
approval of Visioneer's stockholders of the merger agreement and the merger is
not obtained at a meeting held for the purpose of obtaining such approval or any
adjournment thereof and the board of directors of Visioneer has withdrawn or
modified or proposed publicly to withdraw or modify its approval or
recommendation of the merger or the merger agreement.
 
                                       80
<PAGE>   87
 
     Except as otherwise provided above, all fees and expenses incurred in
connection with the merger agreement and the merger will be paid by the party
incurring such expenses, whether or not the merger is consummated, except that
filing fees related to compliance with the HSR Act will be borne equally by
Visioneer and ScanSoft.
 
  State Takeover Laws
 
     Visioneer and its board of directors have agreed to use reasonable efforts
to grant the necessary approvals and take any necessary actions if any "fair
price" or "control share acquisition" statute or other similar statute or
regulation shall become applicable to the transactions contemplated by the
merger agreement.

     ScanSoft must deposit or cause to be deposited approximately $10,500,000
with the exchange agent on or prior to the closing date of the merger. The cash
will be provided by Xerox. Visioneer must deposit with the exchange agent on or
prior to the closing date of the merger an amount in cash equal to the excess of
Visioneer's net book value over its targeted amount. See "The Merger -- Merger
Consideration -- Book Value Adjustment." Visioneer shall provide cash in lieu of
fractional shares.
 
CONDITIONS TO THE CONSUMMATION OF THE MERGER
 
     The respective obligations of Visioneer and ScanSoft to consummate and

       foregoing be pending; nor shall there be any action taken, or any
       statute, rule, regulation or order enacted, entered, enforced or deemed

     The voting agreement will terminate upon the earliest to occur of: (1) the

merger into or consolidation with any other corporation or if Visioneer effects
any other transaction(s) in which more than 50% of its voting power is disposed
of; (2) such time as XIS owns less than 10% of Visioneer's outstanding voting
stock; or (3) such time as the non-Xerox parties to the voting agreement own, in
the aggregate, less than 7% of the Visioneer's outstanding voting stock,
provided, however, that if such time occurs prior to the second anniversary of
the effective time of the merger and XIS holds at such time shares of
Visioneer's Series B preferred stock, the voting agreement will not terminate
until the earlier of (x) the second anniversary of the effective time and (y)
the date on which XIS (together with its affiliates) no longer hold any shares
of Visioneer's preferred stock.
 
  Stockholders' Voting Agreement
 
     The following summary describes the material provisions of a Stockholders'
Voting Agreement between ScanSoft and the Investors. A copy of the Stockholders
Voting Agreement is attached as Annex B to this proxy statement/prospectus and
is incorporated herein by reference. This summary is qualified in its entirety
by reference to the Stockholders Voting Agreement.
 
     Voting Arrangements. Pursuant to the Stockholders Voting Agreement, the
Investors, severally and jointly, have agreed that at any meeting of the
Visioneer stockholders called to vote upon the merger agreement and the merger
or in any other circumstances upon which a vote, consent or other approval
(including by written consent) with respect to the merger agreement and the
merger is sought, each Investor shall vote the number of shares of Visioneer
common stock it owns (A) in favor of the merger and the adoption by Visioneer of
the merger agreement and (B) against (1) any merger agreement or merger (other
than the merger agreement and the merger), consolidation, combination, sale of
substantial assets (other than the sale of the hardware business),
reorganization, recapitalization, dissolution, liquidation or winding up of or
involving Visioneer; or (2) any amendment of Visioneer's certificate of
incorporation or bylaws or other proposal or transaction involving Visioneer,
which amendment or other proposal or transaction would in any manner impede,
frustrate, prevent, delay or nullify the merger, the merger agreement or any of
the other transactions contemplated by the merger agreement or change in any
manner the voting rights of any class of capital stock of Visioneer. The
Investors further agreed not to take any action inconsistent with the foregoing.
 
     Transfer Restriction. Under the Stockholders Voting Agreement, the
Investors have agreed not to: (1) transfer, sell, pledge, assign or otherwise
dispose of (including by gift), or enter into any contract, option or other
arrangement (including any profit sharing arrangement) with respect to the
transfer of, any of their shares of Visioneer common stock to any person, other
than pursuant to the terms of the merger, unless the transferee agrees to be
bound by the terms of the agreement; or (2) enter into any voting arrangement,
whether by proxy, power-of-attorney, voting agreement, voting trust or
otherwise, which restrictions terminate on the earlier of (A) the effective time
of the merger or (B) either the termination of the merger agreement or six
months thereafter, depending on the basis for termination of the merger
agreement.
 
     No Solicitation. During the term of the Stockholders Voting Agreement, the
Investors shall not, nor shall they permit any of their affiliates or any
director, officer, employee, investment banker, attorney or other adviser or
representative of any of the foregoing to: (1) directly or indirectly, solicit,
initiate or knowingly encourage the submission of, any Takeover Proposal; or (2)
directly or indirectly, participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to, or take any
other action to facilitate any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal.
 
     Grant of Irrevocable Proxy. Under the Stockholders Voting Agreement, the
Investors revoked all previous proxies (if any) with respect to their shares of
Visioneer common stock. Further, the Investors agreed that if they fail to
comply with the voting arrangements discussed above, such failure shall result,
without any further action by an Investor, in the irrevocable appointment of
ScanSoft, and any person or persons who may be designated by ScanSoft as
permitted under applicable law, and each of such person(s) individually, as the
 
                                       85
<PAGE>   92
 
Investor's proxy and attorney-in-fact (with full power of substitution), for and
in the name, place and stead of the Investor, to vote the Investor's shares of
Visioneer common stock, or grant a consent or approval in respect of such
shares, in favor of or against, as the case may be, the merger and any alternate
Takeover Proposals, and to execute and deliver an appropriate instrument
irrevocably granting such proxy. The proxy terminates upon any termination of
the Stockholders Voting Agreement in accordance with its terms.
 
     Termination. The Stockholders Voting Agreement will terminate as follows:
 
     - if the transactions contemplated by the merger agreement are not
       consummated, and the merger agreement is terminated because Visioneer's
       stockholders did not approve the merger agreement or Visioneer's board of
       directors failed to recommend the approval of the merger agreement (or
       withdrew or modified its recommendation), upon the six month anniversary
       of the date of termination of the merger agreement;
 
     - if the transactions contemplated by the merger agreement are not
       consummated, and the merger agreement is terminated for any reason other
       than as set forth above, as of the date of termination of the merger
       agreement; and
 
     - if the transactions contemplated by the merger agreement are consummated,
       upon the effective time of the merger.
 
     Notwithstanding the above, if Visioneer receives and publicly announces any
Takeover Proposal prior to the date of termination of the merger agreement and
the transactions contemplated by the merger agreement are not consummated
(regardless of the reason for the termination of the merger agreement), the
Stockholders Voting Agreement will terminate upon the later of (A) the six-month
anniversary of the date of termination of the merger agreement or (B) one month
following the date of the stockholder vote or consent taken in connection with
any such alternative Takeover Proposal.
 
  Registration Rights Agreement
 
     Visioneer and XIS will execute the Registration Rights Agreement, pursuant
to which XIS may demand registration under the Securities Act of some or all of
the shares of common stock to be owned by XIS upon consummation of the merger,
conversion of the Series B preferred stock owned by XIS or pursuant to the
exercise of the warrant. Each such registration will be at Visioneer's expense.
Visioneer may postpone such a demand under certain circumstances. In addition,
XIS may request Visioneer to include shares of common stock held by XIS in any
registration proposed by Visioneer of such common stock under the Securities
Act.
 
  Warrant
 
     At the effective time of the merger, Visioneer will issue to XIS a ten-year
warrant that allows XIS to acquire a number of shares of common stock equal to
the number of options (whether vested or unvested) that remain unexercised at
the termination of any ScanSoft option assumed by the Surviving Corporation in
the merger. The exercise price for each warrant share will be the same as the
exercise price of each assumed ScanSoft option, as adjusted by the exchange
ratio in the merger. If all of the assumed ScanSoft options terminate without
being exercised, XIS would be entitled to purchase approximately 1,836,000
shares of Surviving Corporation common stock. The warrant will be exercisable at
any time; however, XIS may not exercise the warrant prior to two years from the
date of its initial issuance unless, immediately after such exercise, XIS owns
directly or indirectly a number of outstanding shares of Surviving Corporation
common stock that represents less than 45% of the total number of shares of
Surviving Corporation common stock outstanding immediately after such exercise.
 
  Board of Directors and Officers of Surviving Corporation Following the Merger
 
     The merger agreement provides that the officers of ScanSoft immediately
prior to the effective time will be officers of the Surviving Corporation
following the merger until the earlier of their resignation or removal and until
their respective successors are duly elected and qualified, as the case may be.
 
                                       86
<PAGE>   93
 
     The merger agreement also provides that the directors of Visioneer
immediately prior to the effective time will be the directors of the Surviving
Corporation following the merger. As of the effective time, Visioneer's board of
directors shall be increased to include seven members. The following table sets
forth as of December 31, 1998, the name, age and position of each person who is
expected to serve as a director of the Surviving Corporation after the effective
time. Paul A. Ricci will serve as Chairman of the Surviving Corporation's board
of directors. In addition, one additional director will be appointed to the
board. Such candidate has not been identified at this time. After the effective
time, the board of directors will be subject to change from time to time.

    and the percentage of ownership of that person, shares of common stock
    subject to options held by that person that are currently exercisable or
    exercisable within 60 days of December 31, 1998 are deemed outstanding. Such
    shares, however, are not deemed outstanding for the purposes of computing
    the percentage ownership of each other person. The persons named in the

               INFORMATION REGARDING SOLE STOCKHOLDER OF SCANSOFT
 
     As of the date of this proxy statement/prospectus, Xerox Imaging Systems, a
wholly owned subsidiary of Xerox, owns all of the outstanding capital stock of
ScanSoft.
 
RELATIONSHIP WITH XEROX
 
     ScanSoft was originally established as a business unit of Xerox Imaging
Systems, Inc. in 1993 and became a wholly owned subsidiary of XIS in 1996.
Subject to the adjustments described under "The Merger -- Merger
Consideration -- Book Value Adjustment" and assuming no transfers of outstanding
ScanSoft shares or exercises of vested ScanSoft options, XIS will own 45% of the
Surviving Corporation common stock and all of the Series B preferred stock
outstanding immediately after the merger. In addition, XIS will hold a warrant
to purchase approximately 1,836,000 shares of Surviving Corporation common stock
(representing any shares forfeited by ScanSoft optionholders). This will
represent approximately 53.8% of the total equity capital of the Surviving
Corporation on a fully diluted basis immediately after the merger, subject to
the book value adjustment. Immediately following consummation of the merger, XIS
will be the largest stockholder of the Surviving Corporation and will likely
have a strong influence over the business and affairs of the Surviving
Corporation.
 
     For as long as XIS continues to be a significant stockholder of the
Surviving Corporation, XIS will be able, among other things, to strongly
influence the outcome of any corporate action requiring approval of holders of a
majority of the common stock, including the election of the Board of Directors
of the Surviving Corporation. In addition, through its representation on the
Board of Directors and ownership of common stock, XIS will be able to strongly
influence certain decisions, including decisions with respect to the Surviving
Corporation's dividend policy, the Surviving Corporation's access to capital
(including borrowing from third party lenders and the issuance of additional
equity securities), merger or other business combinations involving the
Surviving Corporation, the acquisition or disposition of assets by the Surviving
Corporation and any change in control of the Surviving Corporation.
 
     XIS has advised the Surviving Corporation that its current intent is to
hold all of its shares of common stock to be acquired in the merger. However,
there can be no assurance concerning the periods of time during which time XIS
will maintain its ownership of common stock.
 
     The Surviving Corporation's relationship with XIS will also be governed by
the voting agreement and a registration rights agreement, each of which were
described previously, and a license agreement, the material terms of which are
summarized below. The descriptions of agreements set forth below are intended to
be summaries and, while material terms of the agreements are set forth herein,
the descriptions are qualified by reference to the relevant agreements filed as
exhibits to the Registration Statement of which this proxy statement/prospectus
forms a part.
 
LICENSE AGREEMENT
 
     In connection with the merger agreement, Xerox and ScanSoft entered into a
License Agreement dated December 2, 1998, under which Xerox granted to ScanSoft
limited licenses to certain patents and know-how for use in the client or
client-server digital imaging software products that provide at least two of the
following: capture, editing, optical character recognition, communication or
management of digital images. In addition, Xerox assigned certain patents and
trademarks to ScanSoft, subject to a broad license granted back to Xerox. Xerox
also agreed to enter into negotiations with ScanSoft with respect to future
technology for use in the licensed field. Further, ScanSoft agreed to negotiate
an agreement with Xerox, at Xerox's request, providing Xerox with most favored
customer terms and conditions for the purchase or other acquisition of ScanSoft
products. The parties also agreed to enter into a trademark license under which
Xerox would license ScanSoft certain trademarks. The license agreement is
effective for the life of the licensed patents, unless terminated earlier by
Xerox for ScanSoft's breach, bankruptcy event or cessation of an active
business. The license agreement terminates immediately upon the termination of
the merger agreement.
 
OTHER TRANSACTIONS WITH XEROX
 
     ScanSoft currently subleases facilities from Xerox in Palo Alto,
California. In fiscal 1998, ScanSoft made lease payments of approximately
$61,000 to Xerox for the facilities.

                              REGULATORY APPROVALS
 
     The merger is subject to the expiration or termination of the applicable
waiting period under the HSR Act. Certain aspects of the merger will require
notification to, and filings with, certain securities and other authorities in
certain states, including jurisdictions where Visioneer currently operates.
 
ANTITRUST
 
     Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission, the merger may not be consummated until notifications have been
given and certain information has been furnished to the FTC and the Antitrust
Division and the applicable waiting period has expired or been terminated. At
any time before or after consummation of the merger, the Antitrust Division or
the FTC could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the consummation
of the merger or seeking divestiture of substantial assets of Visioneer. At any
time before or after the effective time, any state could take such action under
the antitrust laws as it deems necessary or desirable in the public interest.
Such action could include seeking to enjoin the consummation of the merger or
seeking divestiture of substantial assets of Visioneer. Private parties may also
seek to take legal action under the antitrust laws under certain circumstances.
 
     Based on information available to them, Visioneer and ScanSoft believe that
the merger can be effected in compliance with federal and state antitrust laws.
However, there can be no assurance that a challenge to the consummation of the
merger on antitrust grounds will not be made or that, if such a challenge were
made, Visioneer and ScanSoft would prevail or would not be required to accept
certain adverse conditions in order to consummate the merger.
 
OTHER
 
     The obligations of Visioneer and ScanSoft under the merger agreement are
also subject to the filing of all notices, reports and other requisite filings
and the receipt of all consents, registrations, approvals, permits and
authorizations required to be obtained prior to the effective time by Visioneer
or ScanSoft, or any of their respective subsidiaries, from any governmental
entity in connection with the execution and delivery of the merger agreement and
the consummation of the merger and the other transactions contemplated thereby
upon terms and conditions that are not reasonably likely to have a material
adverse effect on Visioneer or ScanSoft.

                         STOCKHOLDERS' APPRAISAL RIGHTS
 
     HOLDERS OF SHARES OF COMMON STOCK WHO DO NOT VOTE IN FAVOR OF OR CONSENT TO
THE MERGER AND WHO HAVE PROPERLY COMPLIED WITH THE REQUIREMENTS OF SECTION 262
OF THE DELAWARE GENERAL CORPORATION LAW WILL BE ENTITLED TO APPRAISAL RIGHTS
UNDER SECTION 262. SECTION 262 IS REPRINTED IN ITS ENTIRETY AS ANNEX D TO THIS
PROXY STATEMENT/PROSPECTUS. THE FOLLOWING DISCUSSION IS A SUMMARY OF THE LAW
RELATING TO APPRAISAL RIGHTS AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
ANNEX D. THIS DISCUSSION AND ANNEX D SHOULD BE REVIEWED CAREFULLY BY ANY HOLDER
WHO WISHES TO EXERCISE STATUTORY APPRAISAL RIGHTS, IF AVAILABLE, OR WHO WISHES
TO PRESERVE THE RIGHT TO DO SO, AS FAILURE TO COMPLY WITH THE PROCEDURES SET
FORTH HEREIN OR THEREIN WILL RESULT IN THE LOSS OF APPRAISAL RIGHTS, IF
AVAILABLE.
 
     A stockholder of Visioneer who makes the demand described below with
respect to its shares, who continuously is the record holder of such shares
through the effective time, who otherwise complies with the statutory
requirements of section 262 and who neither votes in favor of the merger
agreement nor consents thereto in writing may be entitled to an appraisal by the
Delaware Court of Chancery (the "Delaware Court") of the fair value of its
shares of common stock, exclusive of any element of value arising from the
accomplishment or expectation of the merger, together with a fair rate of
interest, if any, to be paid upon the amount determined to be the fair value.
Except as set forth herein, stockholders of Visioneer will not be entitled to
appraisal rights in connection with the merger.
 
     Under section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the special meeting, not less than 20 days prior
to the meeting, each constituent corporation must notify each of the holders of
its stock for which appraisal rights are available that such appraisal rights
are available and include in each such notice a copy of section 262. This proxy
statement/prospectus will constitute such notice to the stockholders of
Visioneer.
 
     STOCKHOLDERS OF VISIONEER WHO DESIRE TO EXERCISE THEIR APPRAISAL RIGHTS
MUST NOT VOTE IN FAVOR OF THE MERGER AGREEMENT OR THE MERGER AND MUST DELIVER A
SEPARATE WRITTEN DEMAND FOR APPRAISAL TO VISIONEER PRIOR TO THE VOTE BY THE
STOCKHOLDERS OF VISIONEER ON THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY, INCLUDING THE MERGER. A stockholder of Visioneer who signs
and returns a proxy without expressly directing by checking the applicable boxes
on the reverse side of the proxy enclosed herewith that its shares of common
stock be voted against the proposal or that an abstention be registered with
respect to its shares of common stock in connection with the proposal will
effectively have thereby waived its appraisal rights as to those shares of
common stock because, in the absence of express contrary instructions, such
shares of common stock will be voted in favor of the proposal. See "Special
Meeting -- Voting and Revocation of Proxies." Accordingly, a stockholder of
Visioneer who desires to perfect appraisal rights with respect to any of its
shares of common stock must, as one of the procedural steps involved in such
perfection, either (i) refrain from executing and returning the enclosed proxy
and from voting in person in favor of the proposal to approve the merger
agreement, or (ii) check either the "Against" or the "Abstain" box next to the
proposal on such card or affirmatively vote in person against the proposal or
register in person an abstention with respect thereto. A demand for appraisal
must be executed by or on behalf of the stockholder of Visioneer of record and
must reasonably inform Visioneer of the identity of the stockholder of Visioneer
of record and that such record stockholder of Visioneer intends thereby to
demand appraisal of the common stock. A person having a beneficial interest in
shares of common stock that are held of record in the name of another person,
such as a broker, fiduciary or other nominee, must act promptly to cause the
record holder to follow the steps summarized herein properly and in a timely
manner to perfect whatever appraisal rights are available. If the shares of
common stock are owned of record by a person other than the beneficial owner,
including a broker, fiduciary (such as a trustee, guardian or custodian) or
other nominee, such demand must be executed by or for the record owner. If the
shares of common stock are owned of record by more than one person, as in a
joint tenancy or tenancy in common, such 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 and expressly disclose the
fact that, in exercising the demand, such person is acting as agent for the
record owner. If a stockholder holds shares through a broker who in turn holds
the shares through a central securities depository nominee such as Cede & Co., a
demand
 
                                       93
<PAGE>   100
 
for appraisal of such shares must be made by or on behalf of the depository
nominee and must identify the depository nominee as record holder.
 
     A record owner, such as a broker, fiduciary or other nominee, who holds
shares of common stock as a nominee for others, may exercise appraisal rights
with respect to the shares held for all or less than all beneficial owners of
shares as to which such person is the record owner. In such case, the written
demand must set forth the number of shares covered by such demand. Where the
number of shares is not expressly stated, the demand will be presumed to cover
all shares of common stock outstanding in the name of such record owner.
 
     A stockholder of Visioneer who elects to exercise appraisal rights, if
available, should mail or deliver his or her written demand to: Visioneer, Inc.,
34800 Campus Drive, Fremont, California 94555, Attention: President and Chief
Executive Officer.
 
     The written demand for appraisal should specify the name and mailing
address of the stockholder of Visioneer, the number of shares of common stock
owned, and that the stockholder of Visioneer is thereby demanding appraisal of
its shares. A PROXY OR VOTE AGAINST THE MERGER AGREEMENT WILL NOT BY ITSELF
CONSTITUTE SUCH A DEMAND. Within ten days after the effective time, the
Surviving Corporation must provide notice of the effective time to all
stockholders of Visioneer who have complied with section 262.
 
     Within 120 days after the effective time, either the Surviving Corporation
or any stockholder of Visioneer who has complied with the required conditions of
section 262 may file a petition in the Delaware Court, with a copy served on the
Surviving Corporation in the case of a petition filed by a stockholder of
Visioneer, demanding a determination of the fair value of the shares of all
stockholders of Visioneer entitled to appraisal rights. There is no present
intent on the part of Visioneer to file an appraisal petition and stockholders
of Visioneer seeking to exercise appraisal rights should not assume that the
Surviving Corporation will file such a petition or that the Surviving
Corporation will initiate any negotiations with respect to the fair value of
such shares. Accordingly, stockholders of Visioneer who desire to have their
shares appraised should initiate any petitions necessary for the perfection of
their appraisal rights within the time periods and in the manner prescribed in
section 262. If appraisal rights are available, within 120 days after the
effective time, any stockholder of Visioneer who has theretofore complied with
the applicable provisions of section 262 will be entitled, upon written request,
to receive from the Surviving Corporation a statement setting forth the
aggregate number of shares of common stock not voting in favor of the merger
agreement and with respect to which demands for appraisal were received by
Visioneer and the number of holders of such shares. Such statement must be
mailed within 10 days after the written request therefor has been received by
the Surviving Corporation.
 
     If a petition for an appraisal is timely filed and assuming appraisal
rights are available, at the hearing on such petition, the Delaware Court will
determine which stockholders of Visioneer, if any, are entitled to appraisal
rights. The Delaware Court may require the stockholders of Visioneer who have
demanded an appraisal for their shares and who hold stock represented by
certificates to submit their certificates of stock to the Register in Chancery
for notation thereon of the pendency of the appraisal proceedings; and if any
stockholder of Visioneer fails to comply with such direction, the Delaware Court
may dismiss the proceedings as to such stockholder of Visioneer. Where
proceedings are not dismissed, the Delaware Court will appraise the shares of
common stock owned by such stockholders of Visioneer, determining the fair value
of such shares exclusive of any element of value arising from the accomplishment
or expectation of the merger, together with a fair rate of interest, if any, to
be paid upon the amount determined to be the fair value. In determining fair
value, the Delaware Court is to take into account all relevant factors. In
Weinberger v. UOP Inc., the Delaware Supreme Court discussed the factors that
could be considered in determining fair value in an appraisal proceeding,
stating that "proof of value by any techniques or methods which are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered, and that "fair price obviously requires
consideration of all relevant factors involving the value of a company." The
Delaware Supreme Court stated that in making this determination of fair value
the court must consider market value, asset value, dividends, earnings
prospects, the nature of the enterprise and any other facts which could be
ascertained as of the date of the merger which throw light on future prospects
of the merged
 
                                       94
<PAGE>   101
 
corporation. In Weinberger, the Delaware Supreme Court stated that "elements of
future value, including the nature of the enterprise, which are known or
susceptible of proof as of the date of the merger and not the product of
speculation, may be considered." Section 262, however, provides that fair value
is to be "exclusive of any element of value arising from the accomplishment or
expectation of the merger."
 
     Stockholders of Visioneer considering seeking appraisal should recognize
that the fair value of their shares determined under section 262 could be more
than, the same as or less than the consideration they are entitled to receive
pursuant to the merger agreement if they do not seek appraisal of their shares.
The cost of the appraisal proceeding may be determined by the Delaware Court and
taxed against the parties as the Delaware Court deems equitable in the
circumstances. Upon application of a stockholder of Visioneer entitled to
appraisal rights, the Delaware Court may order that all or a portion of the
expenses incurred by any stockholder of Visioneer entitled to appraisal rights
in connection with the appraisal proceeding, including, without limitation,
reasonable attorneys' fees and the fees and expenses of experts, be charged pro
rata against the value of all shares of common stock entitled to appraisal.
 
     Any stockholder of Visioneer who has duly demanded appraisal in compliance
with section 262 will not, after the effective time, be entitled to vote for any
purpose any shares subject to such demand or to receive payment of dividends or
other distributions on such shares, except for dividends or distributions
payable to stockholders of Visioneer of record at a date prior to the effective
time.
 
     At any time within 60 days after the effective time, any stockholder of
Visioneer will have the right to withdraw such demand for appraisal and to
accept the terms offered in the merger; after this period, the stockholder of
Visioneer may withdraw such demand for appraisal only with the consent of the
Surviving Corporation. If no petition for appraisal is filed with the Delaware
Court within 120 days after the effective time, stockholders' rights to
appraisal will cease, and stockholders of Visioneer will be entitled to receive
the merger consideration. Inasmuch as the Surviving Corporation has no
obligation to file such a petition, and Visioneer has no present intention to do
so, any stockholder of Visioneer who desires such a petition to be filed is
advised to file it on a timely basis. Any stockholder of Visioneer may withdraw
such demand for appraisal by delivering to the Surviving Corporation a written
withdrawal of its demand for appraisal and acceptance of the merger
consideration, except that any such attempt to withdraw made more than 60 days
after the effective time will require written approval of the Surviving
Corporation and that no appraisal proceeding in the Delaware Court will be
dismissed as to any stockholder of Visioneer without the approval of the
Delaware Court, and such approval may be conditioned upon such terms as the
Delaware Court deems just. Any stockholder of Visioneer who withdraws such
demand for appraisal or who fails to perfect such demand after the effective
time will be entitled to the merger consideration in accordance with the merger
agreement for each share of common stock owned by such stockholder.
 
                                 LEGAL MATTERS
 
     The validity of the Visioneer common stock issuable pursuant to the merger
and certain other legal matters relating thereto will be passed upon for
Visioneer by Venture Law Group, A Professional Corporation, Menlo Park,
California. Pillsbury Madison & Sutro LLP, Palo Alto, California, is acting as
counsel for Xerox and ScanSoft in connection with certain legal matters relating
to the merger and the transactions contemplated thereby. As of the date of this
proxy statement/prospectus, certain attorneys of Venture Law Group and
affiliated partnerships beneficially own an aggregate of 15,968 shares of
Visioneer common stock.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
ScanSoft, Inc. and Subsidiaries (a Wholly Owned Subsidiary of Xerox
Corporation):
 
     We have audited the accompanying consolidated balance sheets of ScanSoft,
Inc. and subsidiaries (a wholly owned subsidiary of Xerox Corporation) as of
December 31, 1997 and September 30, 1998, and the related consolidated
statements of operations, changes in stockholder's equity and cash flows for
each of the years in the two-year period ended December 31, 1997 and for the
nine months ended September 30, 1998. These consolidated financial statements
are the responsibility of ScanSoft's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of ScanSoft,
Inc. and subsidiaries (a wholly owned subsidiary of Xerox Corporation) as of
December 31, 1997 and September 30, 1998, and the results of their operations
and their cash flows for each of the years in the two-year period ended December
31, 1997 and for the nine months ended September 30, 1998, in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
                    SEPTEMBER 30, 1998 AND DECEMBER 31, 1997
 
(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
(a) THE COMPANY
 
     ScanSoft, Inc. and subsidiaries (the "Company") develops, markets,
distributes and supports systems and software that capture, communicate and
print documents at the desktop. These systems and software products incorporate
advanced technologies to improve document quality and communication, and are
marketed through retail channels, direct channels and strategic original
equipment manufacturer ("OEM") partnerships.
 
     The Company was originally part of the Imaging Systems division of the
Xerox Corporation ("Xerox" or "Parent"), and remains a wholly owned subsidiary
of Xerox.
 
     On September 16, 1996, ScanSoft was incorporated in the State of Delaware,
and all amounts due to Xerox were forgiven and recorded as net parent equity.
 
     On July 1, 1998, ScanSoft formed a wholly owned subsidiary for the purpose
of acquiring XIS UK Limited, a wholly owned sales subsidiary of Xerox
Corporation. Consideration paid on this date in excess of the historical
carrying value of the net assets of XIS UK Limited of approximately $750 has
been recorded as a reduction of equity in net transactions with parent as the
transaction occurred between companies under common control. The consolidated
financial statements include the operations of XIS UK Limited for all periods
presented.
 
(b) BASIS OF PRESENTATION AND RELATIONSHIP WITH XEROX CORPORATION
 
     The Company is a wholly owned subsidiary of Xerox. The accompanying
consolidated financial statements, which have been prepared as if ScanSoft had
operated as a separate stand-alone entity for all periods presented, include
only revenue and expenses attributable to ScanSoft's operations.
 
     Cash and cash equivalents in the accompanying December 31, 1997 and
September 30, 1998 consolidated balance sheets represent balances of ScanSoft's
foreign entities. All domestic cash receipts and disbursements and worldwide
intercompany charges related to ScanSoft's operations are charged or credited to
the Net Parent Equity account.
 
     The consolidated financial statements include certain allocations from
Xerox for certain research and development costs and general and administrative
expenses such as legal services. Management believes that the allocation method
used to allocate the costs and expenses is reasonable; however, such allocated
amounts may or may not necessarily be indicative of what actual expenses would
have been had ScanSoft operated independently of Xerox.
 
(c) USE OF ESTIMATES
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

                (A WHOLLY OWNED SUBSIDIARY OF XEROX CORPORATION)
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
                    SEPTEMBER 30, 1998 AND DECEMBER 31, 1997
 
(d) PRINCIPLES OF CONSOLIDATION
 
     The accompanying financial statements include the accounts of ScanSoft and
its wholly owned subsidiaries after elimination of significant intercompany
balances and transactions.
 
(e) FOREIGN CURRENCY TRANSLATION
 
     The financial statements of ScanSoft's foreign subsidiaries, where the
local currency is the functional currency, are translated using the exchange
rate in effect at the end of the period for assets and liabilities and average
exchange rates during the year for assets and liabilities, and average exchange
rates during the period for results of operations. The resulting currency
translation adjustments are recorded as adjustments of stockholder's equity.
 
(f) CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents consist of cash on deposit with banks and other
instruments with original maturities of 90 days or less.
 
(g) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The fair value of ScanSoft's cash and cash equivalents, accounts
receivable, and accounts payable approximates their respective carrying amounts,
due to their short-term nature.
 
(h) CONCENTRATION OF CREDIT RISK
 
     Financial assets that potentially subject ScanSoft to significant
concentrations of credit risk consist principally of cash, cash equivalents, and
trade accounts receivable. The Company's cash and cash equivalents are held with
a commercial bank. The Company markets and sells its product throughout the
world and performs ongoing credit evaluations of its customers. The Company
generally does not require collateral on accounts receivable, as many of its
customers are large, well-established companies. The Company maintains reserves
for potential credit losses but historically has not experienced any significant
losses related to individual customers or groups of customers in any particular
industry or geographic area.
 
(i) INVENTORIES
 
     Inventories, which consist principally of costs of product disks and
packaging, are stated at the lower of first-in, first-out cost or market.
 
(j) PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is provided over the estimated useful lives of the
respective assets, generally three to ten years, on a straight-line basis.
Leasehold improvements are amortized on a straight-line basis over the shorter
of the lease terms or the useful lives of the respective assets.
 
     In accordance with the provisions of Statement of Financial Accounting
Standards ("SFAS") No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed of, ScanSoft evaluates long-lived
assets whenever events or changes in circumstances indicate that the carrying
amount of an asset may not be recoverable. Under SFAS No. 121, an impairment
loss would be recognized when

estimated future cash flows expected to result from the use of the asset and its
eventual disposition are less than the carrying amount.
 
(k) SOFTWARE DEVELOPMENT COSTS
 
     In accordance with SFAS No. 86, Accounting for the Costs of Computer
Software to Be Sold, Leased or Otherwise Marketed, ScanSoft capitalizes software
development costs incurred subsequent to determining a product's technological
feasibility. Such costs are amortized on a straight-line basis over the
estimated useful life of the product, generally one to two years. Accumulated
amortization of capitalized software costs was $1,078 and $1,558 at December 31,
1997 and September 30, 1998, respectively. Amortization of capitalized software
development costs is included in cost of revenues and amounted to $317, $311,
and $480 for the year ended December 31, 1996 and 1997 and the nine months ended
September 30, 1998, respectively.
 
(l) REVENUE RECOGNITION
 
     Prior to January 1, 1998, revenue from product sales to customers was
generally recognized when the product was shipped, provided that no significant
obligations remained and collectibility was considered probable, in accordance
with SOP 91-1, Software Revenue Recognition. Effective January 1, 1998, ScanSoft
adopted the provisions of SOP 97-2, Software Revenue Recognition. For
transactions subsequent to January 1, 1998, revenue from product sales to
customers is generally recognized when (i) persuasive evidence of an arrangement
exists, (ii) delivery has occurred, (iii) ScanSoft's fee is fixed or
determinable, and (iv) collectibility is probable. There was no material change
to ScanSoft's accounting for revenue as a result of the adoption of SOP 97-2.
 
     Revenues from sales to distributors and authorized resellers are subject to
agreements allowing price protection and certain rights of return. Accordingly,
reserves for estimated future returns, exchanges and credits for price
protections are provided for upon revenue recognition. The Company has limited
control over the extent to which products sold to distributors and resellers are
sold through to end users. Accordingly, a portion of ScanSoft's sales may from
time to time result in increased inventory at its distributors and resellers,
which may result in returns or price protection allowances. The Company provides
related reserves which are based on ScanSoft's estimates of inventory held by
its distributors and resellers and the expected sell through of its products by
its distributors and resellers. Actual results could differ from these
estimates.
 
     Certain prepaid product license fees paid by OEMs are deferred and
recognized ratably over the license and maintenance period, typically twelve
months.
 
(m) STOCK-BASED COMPENSATION
 
     The Company applies SFAS No. 123, Accounting for Stock-Based Compensation,
which gives companies the option to adopt the fair value method for expense
recognition of employee stock options and other stock-based awards or to
continue to account for such items using the intrinsic value method as outlined
under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees ("APB 25") with pro forma disclosures of net income or loss as if the
fair value method had been applied. The Company has elected to continue to apply
APB 25 and related interpretations for stock options and other stock-based
awards and has disclosed pro forma net loss and net loss per share as if the
fair value method had been applied.

(n) INCOME TAXES
 
     As a wholly owned subsidiary of Xerox, ScanSoft's operations are included
in the U.S. federal consolidated tax return of Xerox. The provision for income
taxes includes ScanSoft's allocated share of Xerox's consolidated income tax
provision and is calculated on a separate company basis pursuant to the
requirements of SFAS No. 109, Accounting for Income Taxes. The terms of the cost
sharing agreement with Xerox require ScanSoft to pay for any liability that it
might have incurred on a separate basis. However, ScanSoft will not be
reimbursed for any losses which reduce the consolidated tax liability.
 
(o) EARNINGS PER SHARE
 
     The Company applies the provisions of SFAS No. 128, Earnings Per Share.
Basic EPS excludes dilution and is computed by dividing net loss available to
common stockholders by the weighted-average number of common shares outstanding
for the period. Diluted EPS is computed similarly to fully diluted EPS pursuant
to Accounting Principles Board Opinion ("APB") No. 15.
 
     Diluted loss per share has not been presented separately as the outstanding
stock options are anti-dilutive for each of the periods presented.
 
(p) RECENTLY ISSUED ACCOUNTING STANDARDS
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 131, Disclosures about Segments of an Enterprise and Related Information,
effective for ScanSoft as of January 1, 1998. SFAS No. 131 establishes annual
and interim reporting standards relating to the disclosure of an enterprise's
business segments, products, services, geographic areas, and major customers.
The Company operates in one segment.
 
     In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, which will be effective for ScanSoft
beginning with its year ending December 31, 2000. SFAS No. 133 establishes
accounting and reporting standards for derivative instruments embedded in other
contracts and for hedging activities. It requires that an entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The Company does not
expect this statement to have a material impact on its consolidated financial
position or results from operations.
 
     In March 1998, the AICPA issued SOP 98-1, Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use. This SOP applies to
software that is acquired or developed solely for an entity's internal use and
requires the capitalization of qualifying costs in software application
development activities, which include design, coding, installation hardware, and
testing. Qualifying capitalizable computer software costs includes the external
direct costs of materials and services and the payroll related costs of
employees who are directly involved with the internal project. All other costs
related to the project are expensed as incurred.
 
     SOP 98-1 will be effective for internal use computer software costs
incurred in future years commencing with 1999. The Company does not believe that
the adoption of SOP 98-1 will have a material effect on ScanSoft's consolidated
financial position or results of operations.
 
(q) ADVERTISING COSTS
 
     The Company generally expenses advertising costs as incurred, except for
certain costs associated with direct-response advertising, which are deferred
and charged to expense over periods which generally do not exceed 90 days.
Advertising expenses, including amounts reimbursed by ScanSoft for certain
advertising

(4) COMMITMENTS AND CONTINGENCIES
 
     The Company leases its facilities and warehouse space under various
noncancelable operating leases that expire in July 2002. As of December 31,
1998, future minimum lease payments under operating leases were as follows:

December 31, 1996 and 1997 and the nine months ended September 30, 1998,
respectively.
 
     Certain claims arise against ScanSoft in the normal course of business. The
Company believes that the ultimate resolution of these matters will not have a
material adverse effect on its consolidated financial position or results from
operations.

(5) STOCK COMPENSATION PLAN
 
     Effective June 1, 1998, ScanSoft implemented an employee stock option plan
which provides for the issuance of up to 4,000,000 incentive and nonqualified
stock options. Options granted under the Plan vest annually over a four-year
period and expire not more than ten years from the date of grant. Options which
are canceled become available for future grants. At September 30, 1998,
1,558,100 of authorized but unissued common shares were reserved and available
for granting additional options. The weighted-average contractual remaining life
of stock options outstanding at September 30, 1998 is 9.7 years.
 
  Stock Option Plan
 
     Activity in ScanSoft's stock option plan as of September 30, 1998 is as

</TABLE>
 
     The Company applies APB Opinion No. 25 and related interpretations in
accounting for its plan. Accordingly, no compensation costs have been recognized
for its fixed stock option plan. Had compensation cost for such plan been
determined consistent with SFAS No. 123, ScanSoft's reported net loss and loss
per share would not have differed materially from the pro forma amounts.
 
     The weighted-average grant-date fair value of $.09 for each option is
estimated using the Black-Scholes option-pricing model, with the following
weighted-average assumptions: dividend yield of 0%; expected volatility of 0%;
risk free interest rate of 5.5% and an expected life of four years.

</TABLE>
 
     In assessing the realizability of deferred tax assets, ScanSoft considers
whether it is more likely than not that some or all of the deferred tax assets
will not be realized. The Company believes that sufficient uncertainty exists
regarding the realizability of the deferred tax assets; accordingly, valuation
allowances of $804 and $914 have been established at December 31, 1997 and
September 30, 1998, respectively.
 
(7) STOCKHOLDER'S EQUITY
 
     The Company was initially incorporated with 1,000 shares of $1.00 par value
common stock on September 16, 1996. In 1998, ScanSoft's certificate of
incorporation was amended and restated to: (1) increase the number of shares
ScanSoft it is authorized to issue up to 50,000,000 shares, divided into
27,000,000 shares of common stock, par value $.001 per share, and 23,000,000
shares of Preferred Stock, par value $.001 per share; and (2) designate a new
Series A Preferred Stock.
 
     In 1998, ScanSoft issued 16,000,000 shares of Series A Convertible
Preferred Stock ("Series A Preferred Stock"), $.001 par value. The Series A
Preferred Stock is voting. Holders of Series A Preferred Stock are entitled to
dividends, when and if declared, at the rate of $.12 per share per annum and the
dividends are noncumulative. The Series A Preferred Stock is convertible into
common stock at any time by the holder at an initial conversion rate of one to
one. The Series A Preferred Stock automatically converts to common stock upon

     WHEREAS, the Board of Directors of the Company has determined that the
merger of ScanSoft with and into the Company, upon the terms and subject to the
conditions set forth in this Agreement, would be fair to and in the best
interests of the stockholders of the Company, and such Board of Directors and
the Board of Directors of ScanSoft have approved such merger (the "Merger"); and
 
     WHEREAS, the Merger and this Agreement require the affirmative vote of the
holders of a majority of the shares of Common Stock, par value $.001 per share,
of the Company (individually a "Share" and collectively the "Shares"), issued
and outstanding immediately prior to the Effective Time (as defined in Section
1.3) for the approval thereof (the "Company Stockholder Approval"); and
 
     WHEREAS, it is intended that the Merger be treated as a tax-free
reorganization pursuant to the provisions of section 368(a)(1)(A) of the
Internal Revenue Code of 1986, as amended (the "Code"):
 
     NOW, THEREFORE, in consideration of the premises and the representations,
warranties, covenants and agreements herein contained, the parties hereto hereby
agree as follows:
 
                                   ARTICLE I

     SECTION 1.1  The Merger.  Upon the terms and subject to the conditions
hereof, and in accordance with the General Corporation Law of the State of
Delaware (the "DGCL"), ScanSoft shall be merged with and into the Company at the
Effective Time (as defined in Section 1.3). Following the Merger, the separate
corporate existence of ScanSoft shall cease and the Company shall continue as
the surviving corporation (the "Surviving Corporation") and shall succeed to and

with the DGCL.
 
     SECTION 1.2  Closing.  Upon the terms and subject to the conditions of this

Article VII (other than those conditions that by their nature are to be
satisfied at the Closing, but subject to the fulfillment or waiver of those
conditions at Closing), at the offices of Pillsbury Madison & Sutro LLP, 2550
Hanover Street, Palo Alto, California, unless another date, time or place is
agreed to in writing by the parties hereto (the "Closing Date").
 
     SECTION 1.3  Effective Time.  The Merger shall become effective when a
Certificate of Merger (the "Certificate of Merger"), executed in accordance with
the relevant provisions of the DGCL, is duly filed with the Secretary of State
of the State of Delaware, or at such other time as ScanSoft and the Company
shall have agreed upon and specified in the Certificate of Merger. When used in
this Agreement, the term "Effective Time" shall mean the later of the date and
time at which the Certificate of Merger is duly filed with the Secretary of
State of the State of Delaware or such time established by the Certificate of
Merger. The filing of the Certificate of Merger shall be made as soon as
practicable on or after the Closing, provided that this Agreement shall not have

                    EFFECT OF THE MERGER ON THE STOCK OF THE
              CONSTITUENT CORPORATIONS; SURRENDER OF CERTIFICATES
 
     SECTION 2.1  Effect on Stock.  At the Effective Time, by virtue of the
Merger and without any action on the part of the holders of any securities of
ScanSoft or the Company:
 
     (a) Conversion of Shares.  Except as otherwise provided herein and subject
to Section 2.1(d), each Share issued and outstanding immediately prior to the
Effective Time, other than Shares to be retired pursuant to Section 2.1(b)
("Excluded Shares") and any Dissenting Shares (as defined in Section 2.1(i)),
shall be converted into the following (the "Merger Consideration"):
 
          (i) for each Share with respect to which an election to receive cash
     pursuant to Section 2.1(c) has been effectively made, and not revoked or
     lost (collectively, the "Electing Shares"), subject to Section 2.1(d)(ii),
     the right to receive in cash following the Merger an amount equal to $2.06
     (the "Cash Merger Consideration"); and
 
          (ii) for each Share (other than Electing Shares), the right to receive
     one fully paid and non-assessable share of Surviving Corporation Common
     Stock (a "Non-Cash Election Share" and, together with the Cash Merger
     Consideration, the "Merger Consideration"), subject to Section 2.1(d)(iii).
 
     (b) Treasury Stock.  Each Share issued and held in the Company's treasury
or owned by the Company shall be retired and no consideration shall be delivered
in exchange therefor.
 
     (c) Cash Elections.  Each person who, on or prior to the Election Date
referred to herein, is a record holder of Shares will be entitled, with respect
to all or any portion of such holder's Shares, subject to Section 2.1(d), to
make an unconditional election (a "Cash Election") on or prior to such Election
Date to receive the Cash Merger Consideration on the basis hereinafter set
forth.

     (d) Proration.
 
          (i) Notwithstanding anything in this Agreement to the contrary (but
     subject to the provisions of Section 2.4), the aggregate number of Shares
     that shall be converted into the right to receive the Cash Merger
     Consideration at the Effective Time shall be the sum of the Additional
     Share Number (as defined in Section 2.1(g)) and 5,097,000 (such sum, the
     "Cash Election Number").
 
          (ii) If the aggregate number of Electing Shares exceeds the Cash
     Election Number, then a portion of the Electing Shares covered by each Cash
     Election shall be converted into the right to receive Non-Cash Election
     Shares in accordance with the terms of Section 2.1(a) in the following
     manner:
 
             (A) A proration factor (the "Cash Proration Factor") shall be
        determined by dividing the Cash Election Number by the total number of
        Electing Shares.
 
             (B) The number of Electing Shares covered by each holder's Cash
        Election to be converted into the right to receive the Cash Merger
        Consideration shall be determined by multiplying the Cash Proration
        Factor set forth in Section 2.1(d)(ii)(A) above by the total number of
        Electing Shares covered by such Cash Election.
 
             (C) All Electing Shares, other than that number of shares converted
        into the right to receive the Cash Merger Consideration in accordance
        with Section 2.1(d)(ii)(B), shall be converted into the right to receive
        Non-Cash Election Shares (on a consistent basis among holders who made
        the election referred to in Section 2.1(a)(i), pro rata to the number of
        Shares as to which they made such election) as if such Shares were not
        Electing Shares in accordance with the terms of Section 2.1(a)(ii).
 
          (iii) If the number of Electing Shares is less than the Cash Election
     Number, then:
 
             (A) all Electing Shares shall be converted into the right to
        receive the Cash Merger Consideration in accordance with the terms of
        Section 2.1(a)(i);
 
             (B) additional Shares other than Electing Shares, Excluded Shares
        and Dissenting Shares shall be converted into the right to receive the
        Cash Merger Consideration in accordance with the terms of 2.1(a)(i) in
        the following manner:
 
                (1) a proration factor (the "Cash Proration Factor") shall be
           determined by dividing (x) the difference between the Cash Election
           Number and the number of Electing Shares, by (y) the total number of
           Shares other than Electing Shares, Excluded Shares and Dissenting
           Shares; and
 
                (2) the number of Shares in addition to Electing Shares to be
           converted into the right to receive the Cash Merger Consideration
           shall be determined by multiplying the Cash Proration Factor set
           forth in Section 2.1(d)(iii)(B)(1) above by the total number of
           Shares other than Electing Shares, Excluded Shares and Dissenting
           Shares; and
 
             (C) subject to Sections 2.1(e) and (g), Shares subject to clause
        (B) of this paragraph 2.1(d)(iii) shall be converted into the right to
        receive the Cash Merger Consideration in accordance with Section
        2.1(a)(i) (on a consistent basis among holders who held Shares as to
        which they did not make the election referred to in Section 2.1(a)(i),
        pro rata to the number of Shares as to which they did not make such
        election).
 
     (e) Cancellation of Shares.  As of the Effective Time, all Shares (other
than Dissenting Shares, Non-Cash Election Shares and Excluded Shares) issued and
outstanding immediately prior to the Effective Time shall no longer be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each holder of a certificate representing any Non-Cash Election
Shares and Excluded Shares shall, to the extent such certificate represents such
Shares, cease to have any rights with respect thereto, except the right to
receive Cash Merger Consideration upon surrender of such certificate in
accordance with Section 2.3.

     in Section 2.1(g)) of shares of Surviving Corporation Preferred Stock and

preceding the Closing Date (the "Prior Month") if the Closing Date is later than
the 15th day in the month in which the Closing occurs or (Y) of the month

respect to the Company) and consistent with the method of preparation of the
Company Unaudited Interim Balance Sheet (as defined in Section 3.4(b)) and the
ScanSoft Unaudited Interim Balance Sheet (as provided for in Section 4.4) (each,
a "Closing Balance Sheet"); provided, however, that any and all accounting,
legal and financial advisors, finders or brokers or similar fees (including, but
not limited to fees paid to The Brenner Group LLC and Broadview International
LLC) disclosed in Sections 3.11 and 3.26 of the Company Disclosure Schedule and
all Management Incentive Payments disclosed in Section 3.22 of the Company
Disclosure Schedule relating to the transactions contemplated by this Agreement
and the Asset Purchase Agreement shall be accrued if unpaid in the Company

Sheet shall be adjusted to exclude such asset. All such fees of ScanSoft
relating to the transactions contemplated by this Agreement as disclosed in
 
                                       A-5
<PAGE>   126
 
Sections 4.11 and 4.22 of the ScanSoft Disclosure Schedule shall be reflected in
the ScanSoft Closing Balance Sheet as paid or accrued. In addition, in the event
the transactions contemplated by the Asset Purchase Agreement shall have not
occurred as of the date of the Company Balance Sheet, such Balance Sheet shall
give pro forma effect to the closing contemplated by the Asset Purchase
Agreement. Each Closing Balance Sheet shall be completed and delivered to the
other party within ten (10) days prior to the Closing Date. The Company and
ScanSoft shall each prepare a computation of their respective book value as of
the date of the Closing Balance Sheet and shall submit such computation to the
other party in writing at the same time as copies of the Closing Balance Sheets
are delivered. If within five (5) days following delivery of the Closing Balance
Sheets, neither party has given notice of its objection to the Closing Balance
Sheet to the other party (such notice must contain a statement of the basis of
such party's objection), then the Closing Balance Sheets will be used in
computing the net book value. If either party gives such notice of objection,
then the issues in dispute will be submitted to an independent auditor to be
agreed upon between the Company and ScanSoft (the "Auditor") for resolution. If
issues in dispute are submitted to the Auditor for resolution, (i) each party
will furnish to the Auditor such workpapers and other documents and information
relating to the disputed issues as the Auditor may request and are available to
that party, and will be afforded the opportunity to present to the Auditor any
material relating to the determination and to discuss the determination with the
Auditor, and (ii) the determination by the Auditor, as set forth in a notice
delivered to both parties by the Auditor, will be binding and conclusive on the
parties. Each party will bear fifty percent (50%) of the fees of the Auditor for
the resolution of any disputes.
 
     (i) Shares of Dissenting Stockholders.  Notwithstanding anything in this
Agreement to the contrary, any issued and outstanding Shares held by a person (a
"Dissenting Stockholder") who shall not have voted in favor of the Merger or
consented thereto in writing and who shall have demanded properly in writing
appraisal for such Shares pursuant to section 262 of the DGCL and who shall not
have withdrawn such demand or otherwise have forfeited appraisal rights
("Dissenting Shares") shall not be converted into or represent the right to
receive the Merger Consideration. Such stockholders shall be entitled to receive
payment of the appraised value of such Shares in accordance with section 262 of
the DGCL, except that if, after the Effective Time, such Dissenting Stockholder
withdraws his demand for appraisal or fails to perfect or otherwise loses his
right of appraisal, in any case pursuant to the DGCL, his Shares shall be deemed
to be canceled as of the Effective Time and such Dissenting Stockholders shall
be deemed to have elected the right to receive the Merger Consideration as
provided in Section 2.1(a). The Company shall give ScanSoft (i) prompt notice of
any demands for appraisal of Shares received by the Company and (ii) the
opportunity to participate in and direct all negotiations and proceedings with
respect to any such demands. The Company shall not, without the prior written
consent of ScanSoft, make any payment with respect to, or settle, offer to
settle or otherwise negotiate, any such demands.
 
     (j) Fractional Shares.  Notwithstanding any other provision of this
Agreement, no fractional share of Surviving Corporation Common Stock shall be
issued in the Merger. All fractional shares of Surviving Corporation Common
Stock that a holder of Shares would otherwise be entitled to receive as a result
of the Merger shall be aggregated and, if a fractional share results from such
aggregation, such holder shall be entitled to receive, in lieu thereof, an
amount in cash determined by multiplying such fraction by the Cash Merger
Consideration.
 
     SECTION 2.2  Assumption of ScanSoft Options.
 
     (a) At the Effective Time, each outstanding option to purchase common stock
of ScanSoft issued by ScanSoft pursuant to the ScanSoft 1998 Stock Option Plan
(each, a "ScanSoft Option"), whether vested or unvested, shall be assumed by the
Company and constitute an option to acquire, on the same terms and conditions
(including, without limitation, vesting provisions) as were applicable under
such ScanSoft Option prior to the Effective Time, that number of whole shares of
Common Stock of the Surviving Corporation equal to the product of the number of
shares of ScanSoft Common Stock subject to such ScanSoft Option multiplied by
the Exchange Ratio (rounded down to the nearest whole number), and shall have an
exercise price per share of Common Stock of the Surviving Corporation equal to
the quotient obtained by dividing the exercise price per share of the ScanSoft
Common Stock subject to such ScanSoft Option by the Exchange Ratio (rounded up
to the nearest whole cent). All such calculations shall ignore whether or not
such ScanSoft
                                       A-6
<PAGE>   127
 
Option is exercisable as of the Effective Time. At and after the Effective Time,
the Company will honor all obligations with respect to such ScanSoft Options
under the terms of such ScanSoft Options and the ScanSoft Option Plans as in
effect on the date hereof.
 
     (b) As soon as practicable after the Effective Time (but in any event
within thirty (30) business days) the Company shall deliver to each holder of an
outstanding ScanSoft Option an appropriate notice setting forth such holder's
rights pursuant thereto, and such ScanSoft Option shall otherwise continue in
effect on the same terms and conditions as were in effect prior to the Effective
Time.
 
     SECTION 2.3  Surrender of Certificates.
 
     (a) Exchange Agent.  Prior to the record date for the Stockholder Meeting
(as defined in Section 6.1), ScanSoft shall designate a bank or trust company
who shall be reasonably satisfactory to the Company to act as paying agent in
the Merger (the "Exchange Agent"), and prior to the Effective Time, ScanSoft
shall cause to be deposited with the Exchange Agent $10,500,000 and the Company
shall deposit with the Exchange Agent an amount necessary for the payment of the
Excess Company Net Book Value as provided in Section 2.1 following surrender of
Certificates (as defined below) representing Shares as part of the Merger. Funds
made available to the Exchange Agent shall be invested by the Exchange Agent as
directed by the person depositing such funds (the "Depositor"), provided that
such investments shall only be in obligations of or guaranteed by the United
States of America, in commercial paper obligations rated A-1 or P-1 or better by
Moody's Investors Service, Inc. or Standard & Poor's Corporation, respectively,
or in certificates of deposit, bank repurchase agreements or banker's
acceptances of commercial banks whose commercial paper is rated A-1 or P-1 (it
being understood that any and all interest or income earned on funds made
available to the Exchange Agent pursuant to this Agreement shall be turned over
to the Depositor).
 
     (b) Exchange Procedure.  The Company shall prepare and mail a form of
election, which form shall be subject to the reasonable approval of ScanSoft
(the "Form of Election"), with the Proxy Statement (as defined in Section 3.8)
to the record holders of Shares (other than to holders of Excluded Shares) as of
the record date for the Stockholder Meeting (as defined in Section 6.1), which
Form of Election shall be used by each record holder of Shares to indicate the
form of Merger Consideration such holder elects to receive for any or all Shares
held by such holder. The Company will make the Form of Election and the Proxy
Statement available to all persons who become holders of Shares during the
period between the record date for the Stockholder Meeting and the Election Date
referred to below. The Form of Election shall specify that delivery shall be
effected, and risk of loss and title to each certificate or certificates
representing outstanding Shares (the "Certificates") shall pass, only upon
proper delivery of the Certificates to the Exchange Agent, shall be in a form
and have such other provisions as ScanSoft may reasonably specify and shall
contain instructions for use in effecting the surrender of Certificates in
exchange for Merger Consideration. Promptly following the Effective Time,
assuming surrender of a Certificate to the Exchange Agent or to such other agent
or agents as may be appointed by ScanSoft, together with such Form of Election,
duly executed and completed in accordance with the instructions thereto, and
such other documents as may reasonably be required by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor the
Merger Consideration for each Share formerly represented by such Certificate,
and the Certificate so surrendered shall forthwith be canceled. If payment of
the Cash Merger Consideration is to be made to a person other than the person in
whose name the Certificate so surrendered is registered, it shall be a condition
of payment that the Certificate so surrendered shall be properly endorsed or
otherwise be in proper form for transfer and that the person requesting such
payment shall pay any transfer or other taxes required by reason of the payment
of the Cash Merger Consideration to a person other than the registered holder of
the Certificate surrendered or shall have established to the satisfaction of the
Surviving Corporation that such tax has been paid or is not applicable. Until
surrendered as contemplated by this Section 2.3, each Certificate (other than
Certificates representing Dissenting Shares or Excluded Shares) shall be deemed
at any time after the Effective Time to represent only the right to receive upon
such surrender the Non-Cash Electing Shares or the Cash Merger Consideration,
without interest, into which the Shares theretofore represented by such
Certificate shall have been converted pursuant to Section 2.1. No interest will
be paid or will accrue on the Cash Merger Consideration payable upon the
surrender of any Certificate. The Exchange Agent shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement to
any holder of a
                                       A-7
<PAGE>   128
 
Certificate such amounts as the Exchange Agent is required to deduct and
withhold with respect to the making of payment under the Code (as hereinafter
defined) or under any provision of state, local or foreign tax law. To the
extent that amounts are so withheld by the Exchange Agent, such withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
holder of the Shares in respect of which such deduction and withholding was made
by the Exchange Agent.
 
     Any such holder's election with respect to the Merger Consideration shall
have been properly made only if the Exchange Agent (as defined in Section
2.3(a)) shall have received at its designated office by 5:00 p.m., New York City
time on the date of the Stockholder Meeting, a Form of Election properly
completed and signed and accompanied by certificates for the Shares to which
such Form of Election relates, duly endorsed in blank or otherwise in form
acceptable for transfer on the books of the Company (or by an appropriate
guarantee of delivery of such certificates as set forth in such Form of Election
from a firm which is a participant in the Security Transfer Agent's Medallion
Program, provided such certificates are in fact delivered to the Exchange Agent
within three (3) Nasdaq Stock Market trading days after the date of execution of
such guarantee of delivery).
 
     Any Form of Election may be changed by the holder submitting it to the
Exchange Agent only by written notice received by the Exchange Agent prior to
5:00 p.m., New York City time, on the Election Date (unless ScanSoft and the
Company determine not less than two (2) business days prior to the Election Date
that the Effective Time is not likely to occur within five (5) business days
following the date of the Stockholder Meeting, in which case the Form of
Election will remain revisable until a subsequent date which shall be a date
prior to the Effective Time determined by ScanSoft and the Company). In
addition, all Forms of Election shall automatically be revoked if the Exchange
Agent is notified in writing by ScanSoft and the Company that the Merger has
been abandoned. If a Form of Election is revoked in accordance with the
preceding sentence, the Certificate or Certificates (or guarantees of delivery,
as appropriate) for the Shares to which such Form of Election relates shall be
promptly returned to the holder submitting the same to the Exchange Agent.
 
     The determination of the Exchange Agent shall be binding as to whether or
not elections have been properly made, changed or revoked pursuant to this
Section 2.1 with respect to Shares and when elections, changes or revocations
were received by it. If the Exchange Agent determines that any election to
receive Cash Merger Consideration in exchange for Electing Shares was not
properly made with respect to Shares, such Shares shall be treated by the
Exchange Agent as Non-Cash Election Shares at the Effective Time. The Exchange
Agent shall also make all computations as to the allocation and the proration
contemplated by Section 2.1(d), and any such computation shall be conclusive and
binding on the holders of Shares. The Exchange Agent may, with the mutual
agreement of ScanSoft and the Company, make such rules as are consistent with
this Section 2.1 for the implementation of the elections provided for herein as
shall be necessary or desirable fully to effect such elections.
 
     (c) No Further Ownership Rights in Shares Exchanged for Cash.  All Cash
Merger Consideration paid upon the Closing in accordance with the terms of this
Article II shall be deemed to have been paid in full satisfaction of all rights
pertaining to the Cash Election Shares, prorated in accordance with Section
2.1(d) above, theretofore represented by such Certificates.
 
     (d) Closing of Transfer Books.  At the Effective Time, the stock transfer
books of the Company shall be closed, and there shall be no further registration
of transfers on the stock transfer books of the Surviving Corporation of the
Shares that were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation or
the Exchange Agent for any reason, they shall be canceled and exchanged as
provided in this Article II.
 
     (e) Distributions With Respect to Unexchanged Shares.  No cash payment in
lieu of fractional shares shall be paid to any holder of any unsurrendered
Certificate until the surrender of such Certificate in accordance with this
Article II. Subject to the effect of applicable laws, following surrender of any
such Certificate, there shall be paid to the holder of the Certificate
representing whole Non-Cash Election Shares issued in connection therewith,
without interest, at the time of such surrender or as promptly thereafter as
 
                                       A-8
<PAGE>   129
 
practicable, the amount of any cash payable in lieu of a fractional Non-Cash
Election Share to which such holder is entitled pursuant to Section 2.1(j).
 
     (f) Termination of Payment Fund.  Any portion of the funds made available
to the Exchange Agent which remains undistributed to the holders of Shares for
nine (9) months after the Effective Time shall be delivered to the Depositor,
upon demand, and any holders of Shares who have not theretofore complied with
this Article II and the instructions set forth in the Form of Election shall
thereafter look only to the Surviving Corporation (subject to abandoned
property, escheat or other similar laws) and only as general creditors thereof
for payment of their claim for cash (without interest), if any, Non-Cash
Election Shares, if any, or any cash in lieu of fractional Non-Cash Election
Shares to which such holders may be entitled.
 
     (g) No Liability.  None of ScanSoft, the Company, the Exchange Agent or any
other person shall be liable to any person in respect of any Non-Cash Election
Shares (or dividends or distribution with respect thereto) or cash delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law.
 
     (h) Lost Certificates.  In the event any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Company, the posting by such person of a bond in such reasonable amount as
the Company may direct as indemnity against any claim that may be made against
it with respect to such Certificate, the Exchange Agent shall issue in exchange
for such lost, stolen or destroyed Certificate the Merger Consideration to which
such person is entitled pursuant to this Agreement.
 
     (i) Affiliates.  Notwithstanding anything herein to the contrary,
Certificates surrendered for exchange by any "Affiliate" (as determined pursuant
to Section 3.19) of the Company shall not be exchanged until the Company has
received a written agreement from such person as provided in Section 3.19
hereof.
 
     (j) Exchange of Stock Certificates.  As soon as reasonably practicable
after the Effective Time, the Exchange Agent shall mail to each holder of record
of Non-Cash Election Shares new certificates representing such Non-Cash Election
Shares. Although certificates representing Non-Cash Election Shares which are
not so exchanged will be deemed for all purposes to represent validly issued and
outstanding shares of Surviving Corporation Common Stock, such certificates will
not be transferable on the books of the Company. Any holder of a certificate
which represents some Shares entitled to receive the Cash Merger Consideration
and some Non-Cash Election Shares shall receive in exchange therefor the Cash
Merger Consideration for the Electing Shares pursuant to Section 2.3(b) (subject
to the adjustments set forth in Section 2.1) and a new certificate for the
Non-Cash Election Shares pursuant to this Section 2.3(j).
 
     SECTION 2.4  Adjustments to Prevent Dilution.  In the event that prior to
the Effective Time there is a change in the number of Shares issued and
outstanding as a result of a reclassification, stock split (including a reverse
split), stock dividend or distribution, or other similar transaction, the Cash
Merger Consideration, Cash Election Number and Exchange Ratio shall be equitably
adjusted to eliminate the effects of such event.

registered or licensed to do business as a foreign corporation in any

otherwise acquire any shares of capital stock of the Company.
 
     SECTION 3.4  SEC Filings; Financial Statements.
 
     (a) The Company has delivered or made available to ScanSoft accurate and

or superseded by a later filing, then on the date of such filing): (i) each of
the Company SEC Documents filed with the SEC complied in all material respects
with the applicable requirements of the Securities Act or the Exchange Act and
the rules and regulations under either of them (as
 
                                      A-10
<PAGE>   131
 
the case may be) as of the date of such filing and any the Company SEC Documents
filed after the date hereof will so comply; and (ii) none of the Company SEC
Documents contained any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.
 
     (b) The financial statements (including any related notes) contained in the
Company SEC Documents filed with the SEC (the "Company Financial Statements"):
(i) complied as to form in all material respects with the published rules and
regulations of the SEC applicable thereto; (ii) were prepared in accordance with
GAAP applied on a consistent basis throughout the periods covered (except as may
be indicated in the notes to such financial statements or, in the case of
unaudited statements, as permitted by Form 10-Q of the SEC, and except that the
unaudited financial statements may not contain footnotes and other information
required for complete financial statements), and (iii) fairly present the
consolidated financial position of the Company as of the respective dates
thereof and the consolidated results of operations of the Company for the
periods covered thereby. All adjustments (consisting of recurring accruals)
considered necessary for a fair presentation of the financial statements have
been included. The audited consolidated balance sheet of the Company included in
the Company's Annual Report on Form 10-K for the year ended December 28, 1997 is
sometimes referred to herein as the "1997 Balance Sheet" and the unaudited
consolidated balance sheet of the Company as of September 27, 1998 is sometimes
referred to herein as the "the Company Unaudited Interim Balance Sheet." All
financial statements (including any related notes) contained in the Company SEC
Documents filed after the date hereof shall meet the conditions set forth in

accordance with GAAP and Statement of Position 97-2 entitled "Software Revenue
Recognition," (SOP 97-2) dated October 27, 1997, issued by the American
Institute of Certified Public Accountants. The Company recognizes revenue when
all of the following criteria are met: (i) persuasive evidence of an arrangement
exists; (ii) delivery has occurred; (iii) the Company's fee is fixed or
determinable; and (iv) collectibility is probable. Prior to January 1, 1998, the
Company recognized revenue in accordance with Statement of Position 91-1
entitled "Software Revenue Recognition." If the Company had used SOP 97-2 in
prior years, the Company's revenue would not be materially different than that
reported.

     SECTION 3.6  Leasehold; Equipment.  The Company does not own any real
property or any interest in real property, except for the leaseholds created
under the real property leases identified in Item 3.6 of the Company Disclosure
Schedule (which Item 3.6 indicates that such leaseholds are included as part of
the Purchased Assets). All such real property is being leased pursuant to lease
agreements that are in full force and effect, are valid and effective in
accordance with their respective terms, and there is not, under any of such
leases, any existing default or event of default (or event which with notice or
lapse of time, or both, would constitute a default). Item 3.6 of the Company
Disclosure Schedule accurately identifies all material equipment leased by the
Company and indicates whether such equipment constitutes Software Assets. All
material items of equipment and other tangible assets owned by or leased to the
Company are adequate for the uses to which they are being put, are in good
condition and repair (ordinary wear and tear excepted).
 
     SECTION 3.7  Title to Assets.  The Company owns, and has good, valid and
marketable title to, or in the case of leased properties and assets, valid
leasehold interests in, all of its tangible properties and assets, real,
personal and mixed. All of said assets are owned or leased by the Company free
and clear of any encumbrances, except for (x) any lien for current taxes not yet
due and payable, and (y) minor liens that have arisen in the ordinary course of
business and that do not (in any case or in the aggregate) materially detract
from the value of the assets subject thereto or materially impair the operations
of the Company. Item 3.7 sets forth a list of all material tangible personal
property and assets of the Company and which of such assets constitute Software
Assets.
 
     SECTION 3.8  Receivables; Significant Customers of the Business.
 
     (a) Item 3.8(a) of the Company Disclosure Schedule provides an accurate and
complete breakdown and aging of all accounts receivable of the Company as of the
date of the Company Unaudited Interim Balance Sheet. All such accounts
receivable are current, and the Company believes that there is reasonable basis
that such accounts receivable will be collected (net of the allowance of
doubtful accounts set forth on the Company Unaudited Interim Balance Sheet,
which allowance the Company believes is reasonable).
 
     (b) Item 3.8(b) of the Company Disclosure Schedule contains an accurate and
complete list as of date of this Agreement of all outstanding loans and advances
made by the Company to any employee, director, consultant or independent
contractor of the Company, other than routine travel or relocation advances made
to employees in the ordinary course of business. There are no such loans and
advances existing as of the Closing Date.
 
     (c) Item 3.8(c) of the Company Disclosure Schedule sets forth a complete
and accurate list of all Significant Customers of the Company's Software
Business and Hardware Business, respectively. For purposes of this Agreement,
"Significant Customers" are the thirty customers of the Company (including
without limitation original equipment manufacturers and royalty-paying
customers) that have effected the most purchases from the Company, in dollar
terms, and accounted for the most revenues for the Company, in dollar terms,
during the eight fiscal quarter period ended September 27, 1998. None of the
Company's Significant Customers has canceled or returned or, to the Company's
knowledge, is currently attempting or threatening to cancel or return, any
purchases from, orders to or services provided by the Company. The Company has
not received any material customer complaints concerning its products and/or
services.
 
     SECTION 3.9  Proprietary Assets.
 
     (a) Item 3.9(a) of the Company Disclosure Schedule sets forth a list of all
patents and patent applications, trademarks (whether or not registered),
trademark applications, trade names, fictitious business names, service marks
(whether or not registered), service mark applications, copyrights (whether or
not registered), copyright applications, maskworks, maskwork applications,
computer software, computer programs (in source and executable form) and
proprietary products of the Company and which of such Proprietary Assets are
Purchased Assets. Item 3.9(a) of the Company Disclosure Schedule indicates each
Proprietary Asset of the Company registered with any Governmental Body or for
which an application has been filed with any Governmental Body and the names of
the jurisdictions covered by the applicable registration or application. For
purposes of this Section 3.9, all Proprietary Assets of the Company that are not
Purchased Assets being sold to Primax pursuant to the Asset Agreement shall
hereinafter also be referred to
 
                                      A-13
<PAGE>   134
 
as "Software Proprietary Assets." The Company owns no Proprietary Assets
registered with any Governmental Body or for which an application has been filed
with any Governmental Body other than the Proprietary Assets set forth in Item
3.9(a) of the Company Disclosure Schedule. Item 3.9(a) of the Company Disclosure
Schedule identifies and provides a brief description of each Proprietary Asset
licensed to the Company by any Person (except for any Proprietary Asset that is
licensed to the Company under any third party software license generally
available to the public at a cost of less than $25,000), and identifies the
license agreement under which such Proprietary Asset is being licensed to the
Company. The Company has good and marketable title to all of the Proprietary
Assets identified in Item 3.9(a) of the Company Disclosure Schedule, free and
clear of all liens and other Encumbrances, and has a right to use all of the
Software Proprietary Assets. To the Company's knowledge, the Company is not
obligated to make any payment after the date of this Agreement to any Person for
the use of any Proprietary Asset. To the Company's knowledge, the Company has
not developed jointly with any other Person any Proprietary Asset with respect
to which such other Person has any rights.
 
     (b) The Company has taken all reasonable and appropriate steps to protect
and preserve all Trade Secrets. The use, possession or disclosure by the Company
of any Software Proprietary Assets used in its business but which are not owned
by the Company has been in compliance with the terms and conditions of a valid
and enforceable agreement between the Company and the owner of such Software
Proprietary Assets, or such use, possession or disclosure is otherwise lawful
under the circumstances. To the Company's knowledge, there has been no
unauthorized disclosures of any Trade Secrets, no unauthorized disclosures of
any Proprietary Assets of any third party by the Company or any of its
respective employees or consultants, and there has been no breach of any
confidentiality or nondisclosure agreements to which the Company is a party.
 
     (c) To the Company's knowledge, none of the Company's Software Proprietary
Assets infringes or conflicts with any Proprietary Asset owned or used by any
other Person and the Company is not infringing, misappropriating or making any
unlawful use of, and the Company has not at any time infringed, misappropriated
or made any unlawful use of, or received any notice or other communication (in
writing or otherwise) of any actual, alleged, possible or potential
infringement, misappropriation or unlawful use of, any Proprietary Asset owned
or used by any other Person. To the Company's knowledge, no other Person is
infringing, misappropriating or making any unlawful use of, and no Proprietary
Asset owned or used by any other Person infringes or conflicts with, any
Software Proprietary Asset of the Company.
 
     (d) There has not been any claim by any customer or other Person alleging
that any Software Proprietary Asset of the Company (including each version
thereof that has ever been licensed or otherwise made available by the Company
to any Person) does not conform in all material respects with any specification,
documentation, performance standard, representation or statement made or
provided by or on behalf of the Company. The Company has established adequate
reserves on the Company Unaudited Interim Balance Sheet to cover all costs that
the Company reasonably anticipates to be associated with any obligations that
the Company may have with respect to the correction or repair of programming
errors or other defects in the Proprietary Assets.
 
     (e) The Company's Proprietary Assets constitute all the Proprietary Assets
necessary to enable the Company to conduct its business in the manner in which
such business has been and is being conducted and the Software Proprietary
Assets constitute all software proprietary assets that are necessary to continue
the Software Business following consummation of transactions contemplated by the
Asset Purchase Agreement. The Company has not licensed any of the Proprietary
Assets to any Person on an exclusive basis, and the Company has not entered into
any covenant not to compete or Company Material Contract limiting its ability to
exploit fully any of its Proprietary Assets (including without limitation "most
favorable pricing" clauses in any Contracts) or to transact business in any
market or geographical area or with any Person.
 
     (f) All current and former employees have executed and delivered to the
Company an agreement (containing no exceptions to or exclusions from the scope
of its coverage) that is substantially identical to the form of confidential
information and invention assignment agreement previously delivered to ScanSoft.
All current and former consultants and independent contractors to the Company
have executed and delivered to the Company an agreement (containing no
exceptions to or exclusions from the scope of its coverage) that is
 
                                      A-14
<PAGE>   135
 
substantially identical to the form of consultant confidential information and
invention assignment agreement previously delivered to ScanSoft.
 
     SECTION 3.10  Contracts.
 
     (a) Item 3.10 of the Company Disclosure Schedule identifies each Contract
of the Company that constitutes a "Company Material Contract" and indicates
whether or not each such Contract is a Software Asset. For purposes of this
Agreement, each of the following shall be deemed to constitute a "Company
Material Contract":
 
          (i) (A) any Contract or outstanding offer relating to the employment
     of, or the performance of services by, any employee, (B) any Contract
     pursuant to which the Company is required to make any severance,
     termination or similar payment, bonus or relocation payment or any other
     payment (other than payments in respect of salary) to any current or former
     employee or director of the Company (if any such payment is disclosed on
     Item 3.10 of the Company Disclosure Schedule, such reference also states
     whether or not such payment is an Assumed Liability for purposes of the
     Asset Purchase Agreement) and (C) any Contract or Plan (including, without
     limitation, any stock option plan, stock appreciation plan or stock
     purchase plan), any of the benefits of which may be increased, or the
     vesting of benefits of which may be accelerated;
 
          (ii) any Contract (A) relating to the acquisition, transfer,
     development, sharing, license (to or by the Company), use or other
     exploitation of any Proprietary Asset (except for any Contract pursuant to
     which any Proprietary Asset is licensed to the Company under any third
     party software license generally available to the public); or (B) with
     respect to the distribution or marketing of any products of the Company, in
     each case the absence of which would have a Material Adverse Effect on the
     Company;
 
          (iii) any Contract which provides for indemnification of any officer,
     director, employee or agent of the Company;
 
          (iv) any Contract imposing any material restriction on the right or
     ability of the Company (A) to compete in any market or geographic area with
     any other Person, (B) to acquire any product or other asset or any services
     from any other Person, to sell any product or other asset to or perform any
     services for any other Person or to transact business or deal in any other
     manner with any other Person, or (C) to develop or distribute any

possession or disclosure by ScanSoft of any Proprietary Assets used in its
business but which are not owned by ScanSoft has been in compliance with the

disclosures of any Proprietary Assets of any third party by ScanSoft or any of
its respective employees or consultants, and there has been no breach of any
confidentiality or nondisclosure agreements to which ScanSoft is a party.
 
     (c) To ScanSoft's knowledge, none of ScanSoft's Proprietary Assets
infringes or conflicts with any proprietary asset owned or used by any other
Person and ScanSoft is not infringing, misappropriating or

otherwise shall not constitute a waiver of those rights.

                       IRREVOCABLE PROXY/VOTING AGREEMENT
 
     THIS IRREVOCABLE PROXY/VOTING AGREEMENT (this "Agreement") dated as of
December   , 1998, among SCANSOFT, INC., a Delaware corporation ("ScanSoft"), on
the one hand, and certain stockholders of VISIONEER, INC., a Delaware
corporation ("Visioneer"), listed on Schedule A hereto (each a "Stockholder"
and, collectively, the "Stockholders"), on the other hand,
 
                                  WITNESSETH:
 
     WHEREAS, ScanSoft and Visioneer propose to enter into an Agreement and Plan
of Merger dated as of the date hereof (as the same may be amended or
supplemented, the "Merger Agreement"; capitalized terms used but not defined
herein shall have the meanings set forth in the Merger Agreement) providing that
ScanSoft shall merge with and into Visioneer (the "Merger") upon the terms and
subject to the conditions set forth in the Merger Agreement;
 
     WHEREAS, each Stockholder owns beneficially or of record the number of
shares of Visioneer Common Stock, par value $0.001 per share, of Visioneer (the
"Visioneer Common Stock") set forth opposite its name on Schedule A attached
hereto (the "Subject Shares");
 
     WHEREAS, as a condition to its willingness to enter into the Merger
Agreement, ScanSoft has required that each Stockholder enter into this
Agreement.
 
     NOW, THEREFORE, to induce ScanSoft to enter into, and in consideration of
its entering into, the Merger Agreement, and in consideration of the premises
and the representations, warranties and agreements contained herein, the parties
agree as follows:
 
          1.  Representations and Warranties of Each Stockholder.  Each
     Stockholder hereby, severally and not jointly, represents and warrants to
     ScanSoft as of the date hereof in respect of itself as follows:
 
             (a) Authority.  The Stockholder has all requisite power and
        authority to enter into this Agreement and to consummate the
        transactions contemplated hereby. This Agreement has been duly
        authorized, executed and delivered by the Stockholder and constitutes a
        valid and binding obligation of the Stockholder enforceable in
        accordance with its terms, except that such enforceability (i) may be
        limited by bankruptcy, insolvency, moratorium or other similar laws
        affecting or relating to the enforcement of creditors' rights generally
        and (ii) is subject to general principles of equity. The execution and
        delivery of this Agreement does not, and the consummation of the
        transactions contemplated hereby and compliance with the terms hereof
        will not, conflict with, or result in any violation of, or default (with
        or without notice or lapse of time or both) under any provision of, any
        trust agreement, loan or credit agreement, note, bond, mortgage,
        indenture, lease or other agreement, instrument, permit, concession,
        franchise, license, judgment, order, notice, decree, statute, law,
        ordinance, rule or regulation applicable to the Stockholder or to the
        Stockholder's property or assets the effect of which, in any case, would
        be material and adverse to the ability of the Stockholder to consummate
        the transactions contemplated hereby or to comply with the terms hereof.
 
             (b) The Subject Shares.  The Stockholder is the record and
        beneficial owner of and has the sole right to vote the Subject Shares
        set forth opposite such Stockholder's name on Schedule A attached
        hereto. None of such Subject Shares is subject to any voting trust or
        other agreement, arrangement or restriction, except as contemplated by
        this Agreement.
 
          2.  Covenants of Each Stockholder.  Until the termination of this
     Agreement in accordance with Section 6, each Stockholder, severally and not
     jointly, agrees as follows:
 
             (a) Vote for the Merger.  At any meeting of stockholders of
        Visioneer called to vote upon the Merger and the Merger Agreement or at
        any adjournment thereof or in any other circumstances
                                      AA-1
<PAGE>   179
 
        upon which a vote, consent or other approval (including by written
        consent) with respect to the Merger and the Merger Agreement is sought,
        the Stockholder shall vote (or cause to be voted), or execute a written
        consent in respect of, the Subject Shares in favor of the Merger, the
        adoption by Visioneer of the Merger Agreement and the approval of the
        terms thereof and each of the other transactions contemplated by the
        Merger Agreement. Each Stockholder hereby waives any appraisal rights
        granted pursuant to Section 262 of the General Corporation Law of the
        State of Delaware (the "DGCL") (or any successor provision) to which it
        may otherwise be entitled as a result of the Merger or the other
        transactions contemplated by the Merger Agreement.
 
             (b) Vote Against Alternative Proposals.  At any meeting of
        stockholders of Visioneer or at any adjournment thereof or in any other
        circumstances upon which the stockholders' vote, consent or other
        approval is sought, the Stockholders shall be present (in person or by
        proxy) and shall vote (or cause to be voted) the Subject Shares against
        (i) any merger agreement or merger (other than the Merger Agreement and
        the Merger), consolidation, combination, sale of substantial assets
        (other than the Asset Purchase Agreement), reorganization,
        recapitalization, dissolution, liquidation or winding up of or involving
        Visioneer or (ii) any amendment of Visioneer's certificate of
        incorporation or by-laws or other proposal or transaction involving
        Visioneer or any of its subsidiaries, which amendment or other proposal
        or transaction would in any manner impede, frustrate, prevent, delay or
        nullify the Merger, the Merger Agreement or any of the other
        transactions contemplated by the Merger Agreement or change in any
        manner the voting rights of any class of capital stock of Visioneer.
        Each Stockholder further agrees not to commit or agree to take any
        action inconsistent with the foregoing.
 
             (c) No Transfer of Subject Shares.  Each Stockholder agrees not to
        (i) convert, transfer, sell, pledge, assign or otherwise dispose of
        (including by gift) (collectively, "Transfer"), or enter into any
        contract, option or other arrangement (including any profit sharing
        arrangement) with respect to the Transfer of, any of the Subject Shares
        to any person other than pursuant to the terms of the Merger or (ii)
        enter into any voting arrangement, whether by proxy, power-of-attorney,
        voting agreement, voting trust or otherwise. Notwithstanding the
        foregoing, each Stockholder may Transfer Subject Shares if the proposed
        transferee agrees to be bound by all of the terms of this Agreement and
        delivers a written instrument to ScanSoft evidencing such agreement
        prior to the date of the proposed Transfer.
 
             (d) No Solicitation.  During the terms of this Agreement, each
        Stockholder shall not, nor shall they permit any of their Affiliates or
        any director, officer, employee, investment banker, attorney or other
        advisor or representative of any of the foregoing to, (i) directly or
        indirectly, solicit, initiate or knowingly encourage the submission of,
        any Takeover Proposal (as defined in the Merger Agreement) related to or
        involving Visioneer or (ii) except as set forth in Section 8 of this
        Agreement, directly or indirectly participate in any discussions or
        negotiations regarding, or furnish to any person any information with
        respect to, or knowingly take any other action to facilitate any
        inquires or the making of any proposal that constitutes, or may
        reasonably be expected to lead to, any Takeover Proposal related to or
        involving Visioneer.
 
          3.  Grant of Irrevocable Proxy.
 
             (a) Existing Proxies Revoked.  Each Stockholder hereby represents
        that any proxies heretofore given in respect of the Subject Shares are
        not irrevocable, and that any such proxies are hereby revoked.
 
             (b) Grant of Irrevocable Proxy to ScanSoft.  Each Stockholder
        hereby agrees that, in the event Stockholder shall fail to comply with
        the provisions of Sections 2(a) and 2(b) hereof, as determined by
        ScanSoft in its sole discretion, such failure shall result, without any
        further action by Stockholder, in the irrevocable appointment of
        ScanSoft, and any person or persons who may hereafter be designated by
        ScanSoft as permitted under applicable law, and each of such person(s)
        individually, as the Stockholder's proxy and attorney-in-fact (with full
        power of substitution), for and in the name, place and stead of the
        Stockholder, to vote the Subject Shares, or grant a consent
                                      AA-2
<PAGE>   180
 
        or approval in respect of such Subject Shares, in favor of or against,
        as the case may be, the matters set forth in Sections 2(a) and 2(b). The
        proxy granted hereby shall terminate upon any termination of this
        Agreement in accordance with its terms.
 
             (c) Affirmations.  Each Stockholder hereby affirms that any
        irrevocable proxy granted pursuant to Section 3(b) will be given in
        connection with the execution of the Merger Agreement, and that such
        irrevocable proxy will be given to secure the performance of the duties
        of the Stockholders under this Agreement. If so granted, the
        Stockholders hereby ratify and confirm all that such irrevocable proxy
        may lawfully do or cause to be done by virtue thereof. This proxy and
        power of attorney is irrevocable and coupled with an interest and is
        intended to be irrevocable in accordance with the provisions of Section
        212(e) of the DGCL.
 
          4.  Further Assurances.  Each Stockholder will, from time to time,
     execute and deliver, or cause to be executed and delivered, such additional
     or further consents, documents and other instruments as ScanSoft may
     reasonably request for the purpose of effectively carrying out the
     transactions contemplated by this Agreement.
 
          5.  Assignment.  Except as provided herein, neither this Agreement nor
     any of the rights, interests or obligations hereunder shall be assigned by
     any of the parties hereto without the prior written consent of the other
     parties. Subject to the preceding sentence, this Agreement will be binding
     upon, inure to the benefit of and be enforceable by the parties and their
     respective successors and assigns.
 
          6.  Termination.  This Agreement shall terminate as follows: (i) if
     the transactions contemplated by the Merger Agreement are consummated, this
     Agreement shall terminate upon the Effective Time of the Merger; (ii) if
     the transactions contemplated by the Merger Agreement are not consummated,
     and the Merger Agreement is terminated in accordance with Section 8.1(a),
     Section 8.1(b)(i), Section 8.1(b)(ii), Section 8.1(c)(i), Section
     8.1(c)(ii), Section 8.1(d)(i) or Section 8.1(d)(ii) thereof, this Agreement
     shall terminate as of the date of termination of the Merger Agreement;
     (iii) if the transactions contemplated by the Merger Agreement are not
     consummated, and the Merger Agreement is terminated in accordance with
     Section 8.1(b)(iii) or Section 8.1(c)(iii) thereof, this Agreement shall
     terminate upon the six (6) month anniversary of the date of termination of
     the Merger Agreement; or (iv) notwithstanding anything in this Section 6 to
     the contrary, if the Company receives and publicly announces any Takeover
     Proposal prior to the date of termination of the Merger Agreement and the
     transactions contemplated by the Merger Agreement are not consummated and
     the Merger Agreement is terminated for any reason, this Agreement shall
     terminate upon the later of (A) the six (6) month anniversary of the date
     of termination of the Merger Agreement or (B) one month following the date
     of the stockholder vote or consent taken in connection with such Takeover
     Proposal.
 
          7.  General Provisions.
 
             (a) Amendments.  This Agreement may not be amended except by an
        instrument in writing signed by each of the parties hereto.
 
             (b) Notice.  All notices and other communications hereunder shall
        be in writing and shall be deemed given if delivered personally,
        telecopied (which is confirmed) or sent by overnight courier (providing
        proof of delivery) to ScanSoft in accordance with the notification
        provision contained in the Merger Agreement and to the Stockholders at
        their respective addresses set forth on the books of Visioneer (or at
        such other address for a party as shall be specified by like notice).
 
             (c) Interpretation.  When a reference is made in this Agreement to
        Sections, such reference shall be to a Section to this Agreement unless
        otherwise indicated. The headings contained in this Agreement are for
        reference purposes only and shall not affect in any way the meaning or
        interpretation of this Agreement. Wherever the words "include",
        "includes" or "including" are used in this Agreement, they shall be
        deemed to be followed by the words "without limitation".
 
             (d) Counterparts.  This Agreement may be executed in one or more
        counterparts, all of which shall be considered one and the same
        agreement, and shall become effective when one or more of the
 
                                      AA-3
<PAGE>   181
 
        counterparts have been signed by each of the parties hereto and
        delivered to the other parties, it being understood that each party need
        not sign the same counterpart.
 
             (e) Entire Agreement; No Third-Party Beneficiaries.  This Agreement
        (including the documents and instruments referred to herein) (i)
        constitutes the entire agreement and supersedes all prior agreements and
        understandings, both written and oral, among the parties with respect to
        the subject matter hereof and (ii) is not intended to confer upon any
        person other than the parties hereto, any rights or remedies hereunder.
 
             (f) Governing Law.  This 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 law thereof.
 
             (g) Severability.  If any term, provision, covenant or restriction
        herein, or the application thereof to any circumstance, shall, to any
        extent, be held by a court of competent jurisdiction to be invalid, void
        or unenforceable, the remainder of the terms, provisions, covenants and
        restrictions herein and the application thereof to any other
        circumstances, shall remain in full force and effect, shall not in any
        way be affected, impaired or invalidated, and shall be enforced to the
        fullest extent permitted by law, and the parties hereto shall reasonably
        negotiate in good faith a substitute term or provision that comes as
        close as possible to the invalidated and unenforceable term or
        provision, and that puts each party in a position as nearly comparable
        as possible to the position each such party would have been in but for
        the finding of invalidity or unenforceability, while remaining valid and
        enforceable.
 
          8.  Stockholder Representatives.  Each Stockholder signs solely in its
     capacity as the record holder and/or beneficial owner of such Stockholder's
     Subject Shares and nothing contained herein shall limit or affect any
     actions taken by any officer, director, partner, trustee, affiliate or
     representative of a Stockholder who is or becomes an officer or a director
     of Visioneer or serves Visioneer in any other fiduciary capacity in his or
     her capacity as an officer, director or other fiduciary of Visioneer and
     none of such actions in such capacity shall be deemed to constitute a
     breach of this Agreement.
 
          9.  Enforcement.  The parties agree that irreparable damage would
     occur in the event that any of the provisions of this Agreement were not
     performed in accordance with their specific terms or were otherwise
     breached. It is accordingly agreed that the parties shall be entitled to an
     injunction or injunctions to prevent breaches of this Agreement and to
     enforce specifically the terms and provisions of this Agreement in any
     court of the United States located in the State of Delaware or in a
     Delaware state court, this being in addition to any other remedy to which
     they are entitled at law or in equity. In addition, each of the parties
     hereto (i) consents to submit such party to the personal jurisdiction of
     any Federal court located in the State of Delaware or any Delaware state
     court in the event any dispute arises out of this Agreement or any of the
     transactions contemplated hereby, (ii) agrees that such party will not
     attempt to deny or defeat such personal jurisdiction by motion or other
     request for leave from any such court, (iii) agrees that such party will
     not bring any action relating to this Agreement or the transactions
     contemplated hereby in any court other than a Federal court sitting in the
     state of Delaware or a Delaware state court, (iv) waives any right to trial
     by jury with respect to any claim or proceeding related to or arising out
     of this Agreement or any of the transactions contemplated hereby, and (v)
     appoints The Corporation Trust Company as such party's agent for service of
     process in the state of Delaware.

              CERTIFICATE OF DESIGNATION OF RIGHTS AND PREFERENCES
                    OF SERIES B PREFERRED STOCK OF VISIONEER
 
     A.  Rights Preferences and Restrictions of Series B Preferred Stock.  The
Series B Preferred Stock shall have the voting power, preferences and relative,
participating, optional or other special rights, and the qualifications,
limitations or restrictions thereof, as follows:
 
     1.  Dividend Provisions.
 
     (a) The holders of shares of Series B Preferred Stock shall be entitled to
receive dividends, out of any assets legally available therefor, prior and in
preference to any declaration or payment of any dividend (payable other than in
Common Stock or other securities and rights convertible into or entitling the
holder thereof to receive, directly or indirectly, shares of Common Stock of
this corporation) on the Common Stock of this corporation, at the rate of $0.065
per share of Series B Preferred Stock per annum (as determined on a per annum
basis and an as converted basis for the Series B Preferred Stock) whenever funds
are legally available therefor, payable when, as and if declared by the Board of
Directors. Such dividends shall be non-cumulative. Unless full dividends on the
Series B Preferred Stock for the then current dividend period shall have been
paid or declared and a sum sufficient for the payment thereof set apart: (i) no
dividend whatsoever (other than a dividend payable solely in Common Stock or
other securities and rights convertible into or entitling the holder thereof to
receive, directly or indirectly, additional shares of Common Stock of this
corporation) shall be paid or declared, and no distribution shall be made, on
any Common Stock. Dividends, if declared, must be declared and paid with respect
to all series of Preferred Stock contemporaneously, and if less than full
dividends are declared, the same percentage of the dividend rate will be payable
to each series of Preferred Stock.
 
     (b) After payment of such dividends, any additional dividends or
distributions shall be distributed among all holders of Common Stock and all
holders of Series B Preferred Stock in proportion to the number of shares of
Common Stock which would be held by each such holder if all shares of Series B
Preferred Stock were converted to Common Stock at the then effective conversion
rate.
 
     2.  Liquidation Preference.
 
     (a) In the event of any liquidation, dissolution or winding up of this
corporation, either voluntary or involuntary, the holders of Series B Preferred
Stock shall be entitled to receive, prior and in preference to any distribution
of any of the assets of this corporation to the holders of Common Stock by
reason of their ownership thereof, an amount per share equal to (i) $1.30 for
each outstanding share of Series B Preferred Stock (the "Original Series B Issue
Price") plus an amount equal to all declared but unpaid dividends on each such
share. If upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Series B Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then the entire assets and funds of this corporation
legally available for distribution shall be distributed ratably among the
holders of the Series B Preferred Stock in proportion to the product of the
liquidation preference of each such share and the number of such shares owned by
each such holder.
 
     (b) After the distribution described in section (a) above has been paid,
the remaining assets of this corporation available for distribution to
stockholders shall be distributed among the holders of Common Stock pro rata
based on the number of shares of Common Stock held by each.
 
     3.  No Redemption.  No holder of Series B Preferred Stock shall have any
right to require the corporation or any "related person" (within the meaning of
section 351(g)(3)(B) of the Internal Revenue Code) to redeem or purchase any
shares of Series B Preferred Stock. Similarly, neither the corporation nor any
such related person shall have any right or option to redeem or purchase any
shares of Series B Preferred Stock from any holder thereof.

     4.  Conversion.  The holders of Series B Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):
 
     (a) Right to Convert; Automatic Conversion.
 
          (i) Subject to subsection (c), each share of Series B Preferred Stock
     shall be convertible, at the option of the holder thereof, during the
     periods specified in Section 4(a)(ii) below, at the office of this
     corporation or any transfer agent for the Series B Preferred Stock, into
     such number of fully paid and nonassessable shares of Common Stock as is
     determined by dividing the Original Series B Issue Price by the Conversion
     Price applicable to such shares in effect on the date the certificate for
     such share is surrendered for conversion. The initial Conversion Price per
     share for shares of Series B Preferred Stock shall be the Original Series B
     Issue Price; provided, however, that the Conversion Price for shares of
     Series B Preferred Stock shall be subject to adjustment as set forth in
     subsection 4(c) below.
 
          (ii) The shares of Series B Preferred Stock shall not be convertible
     into Common Stock prior to             , 2001; provided, however, that
     notwithstanding the foregoing, each share of Series B Preferred Stock shall
     be convertible into Common Stock, at the option of the holder thereof, at
     any time after the date on which such holder owns directly or indirectly a
     number of outstanding shares of Common Stock of this corporation that
     represents less than 30.0% of the total number of shares of Common Stock
     outstanding immediately prior to conversion of such share; and provided
     further, however, that such holder shall not be entitled to convert any
     share of Series B Preferred Stock pursuant to this Section 4(a)(ii) if the
     conversion of such share to Common Stock would result in such holder owning
     directly or indirectly a number of outstanding shares of Common Stock of
     this corporation that represents more than 45.0% of the total number of
     shares of Common Stock outstanding immediately after the conversion of such
     share.
 
          (iii) At any time after             , 2001 **[the date two years after
     the Closing Date]**, upon the written consent of the holders of at least
     66 2/3% of the then outstanding shares of Series B Preferred Stock, each
     share of Series B Preferred Stock shall automatically and immediately be
     converted into such number of fully paid and nonassessable shares of Common
     Stock as is determined by dividing the Original Series B Issue Price by the
     Conversion Price applicable to such shares in effect on the date the
     certificate for such share is surrendered for conversion. The initial
     Conversion Price per share for shares of Series B Preferred Stock shall be
     the Original Series B Issue Price; provided, however, that the Conversion
     Price for shares of Series B Preferred Stock shall be subject to adjustment
     as set forth in subsection 4(c) below.
 
     (b) Mechanics of Conversion.  Before any holder of shares of Series B
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, such holder shall surrender the certificate or certificates therefor,
duly endorsed, at the office of this corporation or of any transfer agent for
such Series B Preferred Stock, and shall give written notice by mail, postage
prepaid, to this corporation at its principal corporate office, of the election
to convert the same and shall state therein the name or names in which the
certificate or certificates for shares of Common Stock are to be issued. This
corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Series B Preferred Stock, or to the nominee or nominees
of such holder, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled as aforesaid. Such conversion shall
be deemed to have been made immediately prior to the close of business on the
date of such surrender of the shares of Series B Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date. If the
conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act of 1933, as amended, the conversion
may, at the option of any holder tendering Series B Preferred Stock for
conversion, be conditioned upon the closing with the underwriter(s) of the sale
of securities pursuant to such offering, in which event the person(s) entitled
to receive the Common Stock issuable upon such conversion of shares of Series B
Preferred Stock shall not be deemed to have converted such shares of Series B
Preferred Stock until immediately prior to the closing of such sale of
securities.

from time to time as follows:
 
          (i) In the event this corporation should at any time or from time to
     time after the date upon which any shares of Series B Preferred Stock were
     initially issued (a "Purchase Date") fix a record date for the effectuation
     of a split or subdivision of the outstanding shares of Common Stock or the
     determination of holders of Common Stock entitled to receive a dividend or
     other distribution payable in additional shares of Common Stock or other
     securities or rights convertible into, or entitling the holder thereof to
     receive directly or indirectly, additional shares of Common Stock
     (hereinafter referred to as "Common Stock Equivalents") without payment of
     any consideration by such holder for the additional shares of Common Stock
     or the Common Stock Equivalents (including the additional shares of Common
     Stock issuable upon conversion or exercise thereof), then as of such record
     date (or the date of such dividend distribution split or subdivision if no
     record date is fixed), the Conversion Price of the Series B Preferred Stock
     shall be appropriately decreased so that the number of shares of Common
     Stock issuable on conversion of each share of each such series shall be
     increased in proportion to such increase of outstanding shares.
 
          (ii) If the number of shares of Common Stock outstanding at any time
     after a Purchase Date is decreased by a combination of the outstanding
     shares of Common Stock, then, following the record date of such
     combination, the Conversion Price for the Series B Preferred Stock shall be
     appropriately increased so that the number of shares of Common Stock
     issuable on conversion of each share of each such series shall be decreased
     in proportion to such decrease in outstanding shares.
 
     (d) Other Distributions.  In the event this corporation shall declare a
distribution payable in securities of other persons, evidences of indebtedness
issued by this corporation or other persons, assets (excluding cash dividends)
or options or rights not referred to in subsection 4(c)(i), then, in each such
case for the purpose of this subsection 4(d), the holders of Series B Preferred
Stock shall be entitled to a proportionate share of any such distribution as
though they were the holders of the number of shares of Common Stock of this
corporation into which their shares of Series B Preferred Stock are convertible
as of the record date fixed for the determination of the holders of Common Stock
of this corporation entitled to receive such distribution.
 
     (e) Recapitalization.  If at any time or from time to time there shall be a
recapitalization of the Common Stock (other than a subdivision, combination or
merger or sale of assets transaction provided for elsewhere in this Section 4 or
Section 5), provision shall be made so that the holders of Series B Preferred
Stock shall thereafter be entitled to receive upon conversion of their Series B
Preferred Stock, the number of shares of stock or other securities or property
of this corporation or otherwise, to which a holder of Common Stock deliverable
upon conversion would have been entitled on such recapitalization. In any such
case, appropriate adjustment shall be made in the application of the provisions
of this Section 4 with respect to the rights of the holders of Series B
Preferred Stock after the recapitalization to the end that the provisions of
this Section 4 (including adjustment of the Conversion Price then in effect and
the number of shares purchasable upon conversion of the Series B Preferred
Stock) shall be applicable after that event as nearly equivalent as may be
practicable.
 
     (f) No Impairment.  This corporation will not, by amendment of its
Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by this
corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 4 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of the Series B Preferred Stock against impairment.
 
     (g) Fractional Shares and Certificate as to Adjustments.
 
          (i) No fractional shares shall be issued upon conversion of any share
     or shares of Series B Preferred Stock. All shares of Common Stock
     (including fractions thereof) issuable upon such conversion shall be
     aggregated for purposes of determining whether the conversion would result
     in the issuance of any
 
                                      AB-3
<PAGE>   190
 
     fractional share. If, after the aforementioned aggregation, the conversion
     would result in the issuance of a fraction of a share of Common Stock, the
     corporation shall, in lieu of issuing any fractional share, pay the holder
     otherwise entitled to such fraction a sum in cash equal to the fair market
     value of such fraction on the date of conversion (as determined in good
     faith by the Board of Directors).
 
          (ii) Upon the occurrence of each adjustment or readjustment of the
     Conversion Price of Series B Preferred Stock pursuant to this Section 4,
     this corporation, at its expense, shall promptly compute such adjustment or
     readjustment in accordance with the terms hereof and prepare and furnish to
     each holder of Series B Preferred Stock, a certificate setting forth such
     adjustment or readjustment and showing in detail the facts upon which such
     adjustment or readjustment is based. This corporation shall, upon the
     written request at any time of any holder of Series B Preferred Stock,
     furnish or cause to be furnished to such holder a like certificate setting
     forth (A) such adjustment and readjustment, (B) the Conversion Price for
     Series B Preferred Stock at the time in effect, and (C) the number of
     shares of Common Stock and the amount, if any, of other property which at
     the time would be received upon the conversion of a share of Series B
     Preferred Stock.
 
     (h) Notices of Record Date.  In the event of any taking by this corporation
of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a cash dividend) or other distribution, any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, this corporation shall
mail to each holder of Series B Preferred Stock, at least 20 days prior to the
date specified therein, a notice specifying the date on which any such record is
to be taken for the purpose of such dividend, distribution or right, and the
amount and character of such dividend, distribution or right.
 
     (i) Reservation of Stock Issuable Upon Conversion.  This corporation shall
at all times reserve and keep available out of its authorized but unissued
shares of Common Stock solely for the purpose of effecting the conversion of the
shares of Series B Preferred Stock such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series B Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of Series B Preferred Stock, in
addition to such other remedies as shall be available to the holder of Series B
Preferred Stock, this corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes.
 
     (j) Notices.  Any notice required by the provisions of this Section 4 to be
given to the holders of shares of any series of Preferred Stock shall be deemed
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at his address appearing on the books of this corporation.
 
     5.  Merger, Consolidation or Reorganization.
 
     (a) A consolidation, merger or other reorganization of this corporation
with or into another corporation or other entity or person in which this
corporation shall not be the continuing or surviving entity of such merger,
consolidation or reorganization, or the sale of all or substantially all of this
corporation's properties and assets to any other person, or any transaction or
series of related transactions by this corporation in which an excess of 50% of
this corporation's voting power is transferred shall be deemed to be a
liquidation for all purposes of Section 2 hereof, unless this corporation's
stockholders of record immediately prior to such merger, consolidation,
reorganization, sale or transaction are holders of more than 50% of the voting
equity securities of the surviving corporation.
 
     (b) In the event the requirements of subsection 5(a) are not complied with,
this corporation shall forthwith either:
 
          (i) cause such closing to be postponed until such time as the
     requirements of this Section 5 have been complied with, or
 
                                      AB-4
<PAGE>   191
 
          (ii) cancel such transaction, in which event the rights, preferences
     and privileges of the holders of the Series B Preferred Stock shall revert
     to and be the same as such rights, preferences and privileges existing
     immediately prior to the date of the first notice referred to in subsection
     5(c) hereof.
 
     (c) This corporation shall give each holder of record of Series B Preferred
Stock written notice of such impending transaction not later than 20 days prior
to the stockholders' meeting called to approve such transaction, or 20 days
prior to the closing of such transaction, whichever is earlier, and shall also
notify such holders in writing of the final approval of such transaction. The
first of such notices shall describe the material terms and conditions of the
impending transaction and the provisions of this Section 5, and this corporation
shall thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place earlier than 20 days after this
corporation has given the first notice provided for herein or earlier than ten
days after this corporation has given notice of any material changes provided
for herein; provided, however, that such periods may be shortened upon the
written consent of the holders of a majority of the shares of the Series B
Preferred Stock then outstanding.
 
     6.  Voting Rights.
 
     The holders of Series B Preferred Stock shall not be entitled to vote on
any matters except as expressly provided in Section 242(b)(2) of the Delaware
General Corporation Law. In such event, the holder of each share of Series B
Preferred Stock shall have the right to one vote for each share of Common Stock
into which such Series B Preferred Stock could then be converted. In all cases
any fractional share, determined on an aggregate as-converted basis, shall be
rounded to the nearest whole share (with one-half being rounded upward). If the
Series B Preferred Stockholders are entitled to vote, such holders shall be
entitled, notwithstanding any provision hereof, to notice in accordance with the
bylaws of this corporation of any stockholders' meeting that is called to
consider a matter as to which the Series B Preferred Stockholders would be
entitled to vote.
 
     7.  Status of Converted Stock.  In the event any shares of Series B
Preferred Stock shall be converted pursuant to Section 4 hereof, the shares so
converted shall be canceled and shall not be issuable by this corporation.
 
     8.  No Preemptive Rights.  The holders of the Series B Preferred Stock
shall not have any preemptive rights.

     THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE

                         COMMON STOCK PURCHASE WARRANT
 
                            ------------------------
 
     This certifies that, for good and valuable consideration, Visioneer, Inc.,
a Delaware corporation (the "Company"), grants to Xerox Corporation, a New York
corporation ("Xerox" or the "Warrantholder"), the right to subscribe for and
purchase from the Company the number of fully paid and nonassessable shares (the
"Warrant Shares") of the Company's Common Stock, $0.001 par value (the "Common
Stock") specified herein, at the purchase price per share (the "Exercise Price")
determined as set forth herein, exercisable, subject to the restrictions set
forth herein, during the period (the "Exercise Period") commencing on the date
hereof and ending on                , 200 [THE TENTH ANNIVERSARY OF THE DATE
HEREOF], all subject to the terms, conditions and adjustments herein set forth.
This Warrant is issued in connection with and pursuant to that certain Agreement
and Plan of Merger (the "Merger Agreement"), dated as of December   , 1998, by
and between the Company and ScanSoft, Inc., a Delaware corporation ("ScanSoft").
Capitalized terms used herein not otherwise defined herein shall have the
meanings assigned to them in the Merger Agreement.
 
     1.  Exercise of Warrant.
 
     1.1  Duration and Exercise of Warrant.
 
     (a) Cash Exercise.  This Warrant may be exercised by the Warrantholder by
(i) the surrender of this Warrant to the Company, with a duly executed Exercise
Form specifying the number of Warrant Shares to be purchased, during normal
business hours on any Business Day during the Exercise Period and (ii) the
delivery of payment to the Company, for the account of the Company, by wire
transfer of immediately available funds to a bank account specified by the
Company or by certified or bank cashier's check, of the Exercise Price for the
number of Warrant Shares specified in the Exercise Form in lawful money of the
United States of America. The Company agrees that such Warrant Shares shall be
deemed to be issued to the Warrantholder as the record holder of such Warrant
Shares as of the close of business on the date on which this Warrant shall have
been surrendered and payment made for the Warrant Shares as aforesaid. A stock
certificate or certificates for the Warrant Shares specified in the Exercise
Form shall be delivered to the Warrantholder as promptly as practicable. If this
Warrant shall have been exercised only in part, the Company shall, at the time
of delivery of the stock certificate or certificates, deliver to the
Warrantholder a new Warrant evidencing the rights to purchase the remaining
Warrant Shares, which new Warrant shall in all other respects be identical with
this Warrant. No adjustments shall be made on Warrant Shares issuable on the
exercise of this Warrant for any cash dividends paid or payable to holders of
record of Common Stock prior to the date as of which the Warrantholder shall be
deemed to be the record holder of such Warrant Shares.
 
     (b) Net Issue Exercise.  In lieu of exercising this Warrant pursuant to
Section 1.1(a), this Warrant may be exercised by the Warrantholder by the
surrender of this Warrant to the Company, with a duly executed Exercise Form
marked to reflect Net Issue Exercise and specifying the number of Warrant Shares
to be
                                      AC-1
<PAGE>   193
 
purchased, during normal business hours on any Business Day during the Exercise
Period. The Company agrees that such Warrant Shares shall be deemed to be issued
to the Warrantholder as the record holder of such Warrant Shares as of the close
of business on the date on which this Warrant shall have been surrendered as
aforesaid. Upon such exercise, the Warrantholder shall be entitled to receive
shares equal to the value of this Warrant (or the portion hereof being
exercised) computed as of the date of surrender of this Warrant to the Company
using the following formula:
 
                                X = Y X (A - B)
 
                                 --------------
                                          A
 
<TABLE>
<C>      <C>  <S>
Where X   =   the number of shares of Common Stock to be issued to
              Warrantholder under this Section 1.1(b);
      Y   =   the number of shares of Common Stock otherwise purchasable
              under this Warrant (at the date of such calculation);
 
      A   =   the fair market value of one share of Common Stock (at the
              date of such calculation);
 
      B   =   the Exercise Price (as adjusted to the date of such
              calculation).
</TABLE>
 
     (c) Fair Market Value.  For purposes of Section 1.1(b) "fair market value"
of one share of Common Stock shall mean:
 
          (i) the average closing price per share of the Common Stock on the
     principal national securities exchange on which the Common Stock is listed
     or admitted to trading for the ten (10) Trading Day period ending three (3)
     Trading Days prior to the date of exercise, or,
 
          (ii) if not listed or traded on any such exchange, the average last
     reported sales price per share of the Common Stock on the Nasdaq National
     Market or The Nasdaq SmallCap Market (collectively, "Nasdaq") for the ten
     (10) Trading Day period ending three (3) Trading Days prior to the date of
     exercise, or,
 
          (iii) if not listed or traded on any such exchange or Nasdaq, the
     average of the mean of the bid and asked prices per share of the Common
     Stock as reported in the OTC Bulletin Board or, if not so reported, in the
     "pink sheets" published by the National Quotation Bureau, Inc. for the ten
     (10) Trading Day period ending three (3) Trading Days prior to the date of
     exercise, or,
 
          (iv) if such quotations are not available, the fair market value per
     share of the Common Stock on the date such notice was received by the
     Company as reasonably determined by the Board of Directors of the Company.
 
     1.2  Number of Warrant Shares.  Subject to the limitations on
exercisability set forth in Section 1.4, upon the termination of any Assumed
ScanSoft Option, this Warrant shall entitle the Warrantholder to purchase that
number of Warrant Shares equal to the number of shares of Common Stock subject
to such Assumed ScanSoft Options that remain unexercised at the termination of
such Assumed ScanSoft Option (whether such option shares were vested or
unvested). Accordingly, if all Assumed ScanSoft Options terminate without being
exercised, the Warrantholder would be entitled to purchase an aggregate of
               shares of Common Stock, as such number shall be adjusted from
time to time prior to the termination of each Assumed ScanSoft Option pursuant
to the terms thereof and after such termination pursuant to Section 6 hereof. As
this Warrant becomes exercisable for Warrant Shares pursuant to the provisions
of this Section, the Warrantholder may exercise this Warrant at any time and
from time to time for such number of Warrant Shares as is then presently
exercisable in accordance with the terms of this Section and Section 1.4 hereof.
 
     1.3  Exercise Price.  The Exercise Price shall be equal to the exercise
price of the Assumed ScanSoft Options, as determined pursuant to Section 2.2(a)
of the Merger Agreement. From and after the Effective
 
                                      AC-2
<PAGE>   194
 
Time of the Merger, the Exercise Price shall be adjusted prior to the
termination of each Assumed ScanSoft Option in accordance with the terms thereof
and after such termination in accordance with Section 6 hereof.
 
     1.4  Term of Warrant and Exercisability.
 
     (a) Term of Warrant.  This Warrant shall terminate on                ,
200[9] [THE TENTH ANNIVERSARY OF THE INITIAL WARRANT ISSUANCE DATE].
 
     (b) Exercisability.  This Warrant shall be exercisable in whole or in part
during the Exercise Period; provided, however, that the Warrantholder may not
exercise this Warrant to purchase Warrant Shares prior to                ,
200[1] [THE 2ND ANNIVERSARY OF THE INITIAL WARRANT ISSUANCE DATE] unless,
immediately after such exercise, the Warrantholder owns directly or indirectly a
number of outstanding shares of Common Stock that represents less than 45.0% of
the total number of shares of Common Stock outstanding immediately after such
exercise.
 
     1.5  Payment of Taxes.  The issuance of certificates for Warrant Shares
shall be made without charge to the Warrantholder for any stock transfer or
other issuance tax in respect thereto; provided, however, that the Warrantholder
shall be required to pay any and all taxes which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Warrantholder as reflected upon the books of the
Company.
 
     1.6  Information.  Upon receipt of a written request from a Warrantholder,
the Company agrees to deliver promptly to such Warrantholder a copy of its
current publicly available financial statements and to provide such other
publicly available information concerning the Company as such Warrantholder may
reasonably request (if electronic access to such information via EDGAR is not
then generally available to the public) in order to assist the Warrantholder in
evaluating the merits and risks of exercising the Warrant and to make an
informed investment decision in connection with such exercise.
 
     2.  Restrictions on Transfer; Restrictive Legends.
 
     2.1  Restrictions on Transfer; Compliance with Securities Laws.  This
Warrant and the Warrant Shares issued upon the exercise of the Warrant may not
be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and transferee
(including the delivery of investment representation letters and legal opinions
reasonably satisfactory to the Company, if such are requested by the Company).
The Warrantholder, by acceptance hereof, acknowledges that this Warrant and the
Warrant Shares to be issued upon exercise hereof are being acquired solely for
the Warrantholder's own account and not as a nominee for any other party, and
for investment, and that the Warrantholder will not offer, sell or otherwise
dispose of any Warrant Shares to be issued upon exercise hereof except under
circumstances that will not result in a violation of the Securities Act or any
state securities laws. Upon exercise of this Warrant, the Warrantholder shall,
if requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the Warrant Shares so purchased are being acquired solely for the
Warrantholder's own account and not as a nominee for any other party, for
investment, and not with a view toward distribution or resale.
 
     2.2  Restrictive Legends.  This Warrant shall (and each Warrant issued upon
transfer in whole or in part of this Warrant pursuant to this Section 2 or
issued in substitution for this Warrant pursuant to Section 4 shall) be stamped
or otherwise imprinted with a legend in substantially the following form:
 
          "THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS
     WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED, AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT FILED UNDER SUCH ACT OR PURSUANT TO AN
     EXEMPTION FROM REGISTRATION UNDER SUCH ACT."
 
                                      AC-3
<PAGE>   195
 
Except as otherwise permitted by this Section 2, each stock certificate for
Warrant Shares issued upon the exercise of any Warrant and each stock
certificate issued upon the direct or indirect transfer of any such Warrant
Shares shall be stamped or otherwise imprinted with a legend in substantially
the following form:
 
          "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 EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
     STATEMENT FILED UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM
     REGISTRATION UNDER SUCH ACT."
 
     Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a stock certificate for Warrant Shares without a legend if (i) such
Warrant Shares, as the case may be, have been registered for resale under the
Securities Act or sold pursuant to Rule 144 under the Securities Act (or a
successor rule thereto) or (ii) the Warrantholder has received an opinion of
counsel reasonably satisfactory to the Company that such registration is not
required with respect to such Warrant Shares.
 
     3.  Reservation and Registration of Shares, Etc.
 
     The Company covenants and agrees that all Warrant Shares which are issuable
upon the exercise of this Warrant will, upon issuance, be validly issued, fully
paid and nonassessable and free from all taxes, liens, security interests,
charges and other encumbrances with respect to the issue thereof, other than
taxes in respect of any transfer occurring contemporaneously with such issue.
The Company further covenants and agrees that, during the Exercise Period, the
Company will at all times have authorized and reserved, and keep available free
from preemptive rights, a sufficient number of shares of Common Stock to provide
for the exercise of the rights represented by this Warrant and will, at its
expense, upon each such reservation of shares, procure such listing of such
shares of Common Stock (subject to issuance or notice of issuance) as then may
be required on all stock exchanges on which the Common Stock is then listed or
on Nasdaq.
 
     4.  Exchange, Loss or Destruction of Warrant.
 
     Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant and, in the case of loss, theft
or destruction, of such bond or indemnification as the Company may require, and,
in the case of such mutilation, upon surrender and cancellation of this Warrant,
the Company will execute and deliver a new Warrant of like tenor. The term
"Warrant" as used in this Agreement shall be deemed to include any Warrants
issued in substitution or exchange for this Warrant.
 
     5.  Ownership of Warrant.
 
     The Company may deem and treat the person in whose name this Warrant is
registered as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all
purposes and shall not be affected by any notice to the contrary.
 
     6.  Certain Adjustments.
 
     6.1  Adjustments.  As provided in Sections 1.2 and 1.3 hereof, after the
termination of each Assumed ScanSoft Option, the number of Warrant Shares
purchasable upon the exercise of this Warrant that relate to such terminated
Assumed ScanSoft Option and the Exercise Price shall be subject to adjustment as
follows:
 
          (a) Stock Dividends.  If at any time prior to the exercise of this
     Warrant in full (i) the Company shall fix a record date for the issuance of
     any stock dividend payable in shares of Common Stock or (ii) the number of
     shares of Common Stock shall have been increased by a subdivision or
     split-up of shares of Common Stock, then, on the record date fixed for the
     determination of holders of Common Stock entitled to receive such dividend
     or immediately after the effective date of subdivision or split-up, as the
     case may be, the number of shares of Common Stock to be delivered upon
     exercise of this Warrant will be increased so that the Warrantholder will
     be entitled to receive the number of shares of Common Stock that such
     Warrantholder would have owned immediately following such action had this
     Warrant been exercised immediately prior thereto, and the Exercise Price
     will be adjusted as provided below in paragraph (f).
                                      AC-4
<PAGE>   196
 
          (b) Combination of Stock.  If at any time prior to the exercise of
     this Warrant in full the number of shares of Common Stock outstanding shall
     have been decreased by a combination of the outstanding shares of Common
     Stock, then, immediately after the effective date of such combination, the
     number of shares of Common Stock to be delivered upon exercise of this
     Warrant will be decreased so that the Warrantholder thereafter will be
     entitled to receive the number of shares of Common Stock that such
     Warrantholder would have owned immediately following such action had this
     Warrant been exercised immediately prior thereto, and the Exercise Price
     will be adjusted as provided below in paragraph (f).
 
          (c) Reorganization, Etc.  If at any time prior to the exercise of this
     Warrant in full any capital reorganization of the Company, or any
     reclassification of the Common Stock, or any consolidation of the Company
     with or merger of the Company with or into any other person or any sale,
     lease or other transfer of all or substantially all of the assets of the
     Company to any other person, shall be effected in such a way that the
     holders of Common Stock shall be entitled to receive stock, other
     securities or assets (whether such stock, other securities or assets are
     issued or distributed by the Company or another person) with respect to or
     in exchange for Common Stock, then, upon exercise of this Warrant the
     Warrantholder shall have the right to receive the kind and amount of stock,
     other securities or assets receivable upon such reorganization,
     reclassification, consolidation, merger or sale, lease or other transfer by
     a holder of the number of shares of Common Stock that such Warrantholder
     would have been entitled to receive upon exercise of this Warrant had this
     Warrant been exercised immediately before such reorganization,
     reclassification, consolidation, merger or sale, lease or other transfer,
     subject to adjustments that shall be as nearly equivalent as may be
     practicable to the adjustments provided for in this Section 6.
 
          (d) Fractional Shares.  No fractional shares of Common Stock or scrip
     shall be issued to any Warrantholder in connection with the exercise of
     this Warrant. Instead of any fractional shares of Common Stock that would
     otherwise be issuable to such Warrantholder, the Company will pay to such
     Warrantholder a cash adjustment in respect of such fractional interest in
     an amount equal to that fractional interest of the fair market value of one
     share of Common Stock as of the date of exercise.
 
          (e) Carryover.  Notwithstanding any other provision of this Section 6,
     no adjustment shall be made to the number of shares of Common Stock to be
     delivered to the Warrantholder (or to the Exercise Price) if such
     adjustment represents less than 1% of the number of shares to be so
     delivered, but any lesser adjustment shall be carried forward and shall be
     made at the time and together with the next subsequent adjustment which
     together with any adjustments so carried forward shall amount to 1% or more
     of the number of shares to be so delivered.
 
          (f) Exercise Price Adjustment.  Whenever the number of Warrant Shares
     purchasable upon the exercise of the Warrant is adjusted, as herein
     provided, the Exercise Price payable upon the exercise of this Warrant
     shall be adjusted by multiplying such Exercise Price immediately prior to
     such adjustment by a fraction, of which the numerator shall be the number
     of Warrant Shares purchasable upon the exercise of the Warrant immediately
     prior to such adjustment, and of which the denominator shall be the number
     of Warrant Shares purchasable immediately thereafter.
 
          (g) No Duplicate Adjustments.  Notwithstanding anything else to the
     contrary contained herein, in no event will an adjustment be made under the
     provisions of this Section 6 to the number of Warrant Shares issuable upon
     exercise of this Warrant or the Exercise Price for any event if an
     adjustment having substantially the same effect to the Warrantholder as any
     adjustment that otherwise would be made under the provisions of this
     Section 6 is made by the Company for any such event to the number of shares
     of Common Stock (or other securities) issuable upon exercise of this
     Warrant.
 
     6.2  No Adjustment for Dividends.  Except as provided in Section 1 hereof
or Section 6.1 hereof, no adjustment in respect of any dividends shall be made
during the term of the Warrant or upon the exercise of this Warrant.
 
     6.3  Notice of Adjustment.  Whenever the number of Warrant Shares or the
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, notice of such adjustment or adjustments and a certificate of the
chief financial

Exercise Price of such Warrant Shares after such adjustment, setting forth a

                                VOTING AGREEMENT
 
     This Voting Agreement (the "Agreement") is made as of the   day of
          , 1999, by and among Visioneer, Inc., a Delaware corporation (the
"Company"), Xerox Corporation, a New York corporation ("Xerox"), and the current
holders of shares of the Company's Common Stock listed on Exhibit A
(collectively, the "Current Holders").
 
                                    RECITALS
 
     The Company and ScanSoft, Inc., a Delaware corporation ("ScanSoft") and a
wholly-owned subsidiary of Xerox, are concurrently with the execution of this
Agreement entering into an Agreement and Plan of Merger dated as of the date
hereof (the "Merger Agreement"). Section 6.12 of the Merger Agreement provides
that the Company, Xerox and the Current Holders enter into this Agreement to
provide for the nomination and election of the Company's Board of Directors.
Capitalized terms not otherwise defined herein shall have the meanings ascribed
to them in the Merger Agreement.
 
                                   AGREEMENT
 
     The parties agree as follows:
 
     1.  Election of Directors.
 
          1.1  Board Representation.  As of the Effective Time of the Merger
     Agreement, the Company's Bylaws shall provide for a Board of Directors
     comprised of seven (7) members. At the first meeting of the Board of
     Directors after the Effective Time, the current directors of the Company
     shall vote to appoint to the Board two (2) new directors based on
     nominations received from Xerox and the Company's new Chief Executive
     Officer (the "CEO"). Thereafter, at each annual meeting of the stockholders
     of the Company, or at any meeting of the stockholders of the Company at
     which members of the Board of Directors of the Company are to be elected,
     or whenever members of the Board of Directors are to be elected by written
     consent, Xerox and the Current Holders agree to vote or act with respect to
     their shares so as to elect the following directors:
 
             (a) so long as Xerox owns at least twenty percent (20%) of the
        Company's outstanding voting stock: (i) two (2) members of the Company's
        Board of Directors designated by Xerox; (ii) two (2) members of the
        Company's Board of Directors designated by the four members of the Board
        who were not nominated by Xerox and who are not the CEO (the
        "Non-Xerox/Non-CEO Directors"); (iii) the Company's then current CEO;
        and (iv) two (2) independent members of the Company's Board of Directors
        with relevant industry experience who are designated by at least four
        out of the five directors who are not considered independent directors;
        or
 
             (b) so long as Xerox owns at least ten percent (10%) of the
        Company's outstanding voting stock: (i) one (1) member of the Company's
        Board of Directors designated by Xerox; (ii) two (2) members of the
        Company's Board of Directors designated by the Non-Xerox/Non-CEO
        Directors; (iii) the Company's then current CEO; and (iv) three (3)
        independent members of the Company's Board of Directors with relevant
        industry experience who are designated by at least three out of the four
        directors who are not considered independent directors;
 
          1.2  Appointment of Directors.  In the event of the resignation,
     death, removal or disqualification of a director designated pursuant to
     Section 1.1 above, the party or parties who were authorized to nominate
     such director pursuant to Section 1.1 above shall promptly nominate a new
     director, and, after written notice of the nomination has been given by
     such nominating party or parties to the Company's
 
                                      AE-1
<PAGE>   203
 
     Board of Directors, then each party hereto shall vote its shares of capital
     stock of the Company to elect such nominee to the Board of Directors.
 
          1.3  Removal.  Any director may be removed hereunder only in
     accordance with the Bylaws of the Company and Delaware General Corporation
     Law; provided, however, that Xerox may remove its designated directors at
     any time and from time to time, with or without cause (subject to the
     Bylaws of the Company as in effect from time to time and any requirements
     of law), in its sole discretion, and after written notice to each of the
     parties hereto of the new nominee to replace such director, each party
     hereto shall promptly vote its shares of capital stock of the Company to
     elect such nominee to the Board of Directors.
 
     2.  Additional Representations and Covenants.
 
          2.1  No Revocation; Grant of Proxy.  The voting agreements contained
     herein are coupled with an interest and may not be revoked during the term
     of this Agreement. Should the provisions of this Agreement be construed to
     constitute the granting of proxies, such proxies shall be deemed to be
     coupled with an interest and are irrevocable for the term of this
     Agreement.
 
          2.2  Change in Number of Directors.  The parties hereto will not vote
     for any amendment or change to the Certificate of Incorporation or Bylaws
     providing for the election of more or less than seven (7) directors, or any
     other amendment or change to the Certificate of Incorporation or Bylaws
     inconsistent with the terms of this Agreement.
 
     3.  Termination.
 
          3.1  Termination Events.  This Agreement shall terminate upon the
     earlier of:
 
             (a) The sale, conveyance, disposal, or encumbrance of all or
        substantially all of the Company's property or business or the Company's
        merger into or consolidation with any other corporation (other than a
        wholly-owned subsidiary corporation) or if the Company effects any other
        transaction or series of related transactions in which more than fifty
        percent (50%) of the voting power of the Company is disposed of,
        provided that this Section 3.1(a) shall not apply to a merger effected
        exclusively for the purpose of changing the domicile of the Company;
 
             (b) Such time as Xerox owns less than twenty percent (20%) of the
        outstanding voting stock of the Company; or
 
             (c) Such time as the Current Holders own, in the aggregate, less
        than seven percent (7%) of the outstanding voting stock of the Company;
        provided, however, that if such time occurs prior to the second
        anniversary of the Effective Time and Xerox (or an affiliate thereof)
        holds at such time shares of the Company's Series B Preferred Stock,
        this Agreement shall not terminate pursuant to this Section 3.1(c) until
        the earlier of (X) the second anniversary of the Effective Time and (Y)
        the date on which Xerox (together with its affiliates) no longer hold
        any shares of the Company's Series B Preferred Stock.
 
     4.  Miscellaneous.

     Agreement shall inure to the benefit of and be binding upon the respective
     successors and assigns of the parties. Nothing in this Agreement, express
     or implied, is intended to confer upon any party other than the parties
     hereto or their respective successors and assigns any rights, remedies,
     obligations, or liabilities under or by reason of this Agreement, except as
     expressly provided in this Agreement.
 
          4.2  Amendments and Waivers.  Any term hereof may be amended or waived
     only with the written consent of the Company, Xerox and each of the Current

     held to be unenforceable under applicable law, the parties agree to
     renegotiate such provision in good faith. In the event that the parties
     cannot reach a mutually agreeable and enforceable replacement for such
     provision, then (a) such provision shall be excluded from this Agreement,
     (b) the balance of the Agreement shall be interpreted as if such provision
     were so excluded and (c) the balance of the Agreement shall be enforceable
     in accordance with its terms.

     this Agreement by any party hereto, that this Agreement shall be
     specifically enforceable, and that any breach or threatened breach of this
     Agreement shall be the proper subject of a temporary or permanent
     injunction or restraining order. Further, each party hereto waives any

                         REGISTRATION RIGHTS AGREEMENT
 
     THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made as of the
     th day of             , 1998 by and among VISIONEER, INC., a Delaware
corporation (the "Company") and XEROX CORPORATION, a New York corporation
("Xerox").
 
     WHEREAS, the Company and ScanSoft, Inc., a Delaware corporation and wholly
owned subsidiary of Xerox ("ScanSoft"), have entered into that certain Agreement
and Plan of Merger (the "Merger Agreement") of December   , 1998, whereby Xerox
will receive (i) shares (the "Shares") of Company common stock, $0.001 par value
(the "Common Stock"); (ii) shares of Convertible Preferred Stock of the Company
(the "Preferred Stock"); and (iii) a Warrant (the "Warrant") to purchase shares
of Common Stock (the "Warrant Shares"); and
 
     WHEREAS, the Company and Xerox desire to provide for the rights of Xerox
with respect to the registration of the Shares, the shares of Common Stock
issuable upon conversion of the Preferred Stock into Common Stock (the
"Preferred Shares") and the Warrant Shares and certain other matters according
to the terms of this Agreement.
 
     NOW THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:
 
     1. Registration Rights.
 
          1.1  Definitions.
 
             (a) The term "Commission" means the Securities and Exchange
        Commission or any other federal agency at the time administering the
        Securities Act.
 
             (b) The term "Exchange Act" means the Securities Exchange Act of
        1934, as amended, or any similar successor federal statute and the rules
        and regulations thereunder, all as the same shall be in effect from time
        to time.
 
             (c) The term "Holder" means Xerox, as a holder of Registrable
        Securities, and any holder of Registrable Securities to whom the
        registration rights conferred by this Agreement have been transferred in
        accordance with Section 1.9 hereof;
 
             (d) The term "Other Holders" shall mean persons who are holders of
        record of equity securities of the Company who subsequent to the date
        hereof acquire more than 5% of the outstanding shares of Common Stock
        pursuant to a transaction with the Company and to whom the Company
        grants registration rights pursuant to a written agreement in connection
        with such transaction.
 
             (e) The terms "register," "registered" and "registration" refer to
        a registration effected by preparing and filing a registration statement
        or similar document in compliance with the Securities Act, and the
        declaration or ordering of effectiveness of such registration statement
        or document by the Commission.
 
             (f) The term "Registrable Securities" means (i) the Shares, the
        Preferred Shares and the Warrant Shares, and (ii) Common Stock or
        Preferred Stock, as the case may be, issued as (or issuable upon the

        issued as) a dividend or other distribution with respect to, or in
        exchange for or in replacement of, such Common Stock or Preferred Stock,
        excluding in all cases, however, any Common Stock or Preferred Stock
        sold by a person in a transaction in which such person's registration
        rights are not assigned; provided, however, that any Shares, Preferred
        Shares, Warrant Shares or other securities referred to above that have
        been sold to the public pursuant to a registered public offering or Rule
        144 under the Securities Act shall cease to be Registrable Securities.
 
             (g) The term "Securities Act" means the Securities Act of 1933, as
        amended, or any similar successor federal statute and the rules and

<PAGE>   212
 
          1.2  Request for Registration.
 
             (a) If the Company shall receive a written request from the Holders
        of at least 30% of the Registrable Securities then outstanding that the
        Company file a registration statement under the Securities Act covering
        the registration of at least 10% of the Registrable Securities then
        outstanding (as such number may be appropriately adjusted for stock
        splits, combinations, and the like) or such lesser amount of shares as
        shall constitute all of the Registrable Securities then outstanding,
        then the Company shall, within ten days of the receipt thereof, give
        written notice of such request to all other Holders of Registrable
        Securities and shall, subject to the limitations of subsection 1.2(b),
        use all reasonable commercial efforts to effect as soon as practicable
        the registration under the Securities Act of all Registrable Securities
        that the Holders request to be registered within 20 days of the mailing
        of such notice by the Company in accordance with Section 2.2.
 
             (b) If the Holders of Registrable Securities initiating the
        registration request pursuant to subsection 1.2(a) ("Initiating
        Holders") intend to distribute the Registrable Securities covered by
        their request by means of an underwriting, they shall so advise the
        Company as a part of their request made pursuant to this Section 1.2 and
        the Company shall include such information in the written notice
        referred to in subsection 1.2(a). The underwriter or underwriters shall
        be selected by a majority in interest of the Initiating Holders and
        shall be reasonably acceptable to the Company. In such event, the right
        of any such Holder to include such Holder's Registrable Securities in
        such registration shall be conditioned upon such Holder's participation
        in such underwriting and the inclusion of such Holder's Registrable
        Securities in the underwriting (unless otherwise mutually agreed by a
        majority in interest of the Initiating Holders and such Holder) to the
        extent provided herein. All Holders proposing to distribute their
        securities through such underwriting shall (together with the Company as
        provided in Section 1.4(e)) enter into an underwriting agreement in
        customary form with the underwriter or underwriters selected for such
        underwriting. Notwithstanding any other provision of this Section 1.2,
        if the underwriter advises the Initiating Holders in writing that
        marketing factors require a limitation of the number of shares to be
        underwritten, then the Initiating Holders shall so advise all Holders of
        Registrable Securities that would otherwise be underwritten pursuant
        hereto, and the number of shares of Registrable Securities that may be
        included in the underwriting shall be allocated among all Holders
        thereof, including the Initiating Holders, in proportion (as nearly as
        practicable) to the amount of Registrable Securities owned by each
        Holder; provided, however, that the number of shares of Registrable
        Securities to be included in such underwriting shall not be reduced
        unless all other securities are first entirely excluded from the
        underwriting.
 
             (c) If the Company is qualified to use Form S-3 (or any comparable
        successor form or forms) at the time any registration statement is to be
        filed pursuant to this Section 1.2, such registration statement shall be
        filed on Form S-3. If the Company is not qualified to use Form S-3 at
        the time any registration statement is to be filed pursuant to this
        Section 1.2, such registration statement shall be filed on Form S-1 (or
        any comparable successor form or forms). The Company shall be obligated
        to effect up to two registrations per twelve month period on Form S-3.
        The Company shall be obligated to effect an aggregate of two
        registrations pursuant to this Section 1.2 on Form S-1; provided,
        however that if all or any portion of the Warrant is exercised, the
        Company shall be obligated to effect one additional registration
        pursuant to this Section 1.2 on Form S-1.
 
             (d) Notwithstanding the foregoing, if the Company shall furnish to
        the Initiating Holders a certificate signed by the President of the
        Company stating that in the good faith judgment of the Board of
        Directors of the Company it would be seriously detrimental to the
        Company for such registration statement to be filed and it is therefore
        essential to defer the filing of such registration statement, the
        Company shall have the right to defer such filing for a period of not
        more than 60 days after receipt of the request of the Initiating Holders
        (or, if the Company is engaged or has fixed plans to engage in a
        registered public offering as to which the Holders may include
        Registrable Securities pursuant to Section 1.3, not more than 180 days
        after the effective date of such offering);
 
                                      AF-2
<PAGE>   213
 
        provided, however, that the Company may not utilize this right more than
        once in any 12-month period.
 
          1.3  Company Registration.
 
             (a) If (but without any obligation to do so) the Company proposes
        to register (including for this purpose a registration effected by the
        Company for stockholders other than the Holders) any of its stock or
        other securities under the Securities Act in connection with the public
        offering of such securities solely for cash (other than a registration
        relating solely to the sale of securities to participants in a Company
        stock plan, or a registration on any form which does not include
        substantially the same information as would be required to be included
        in a registration statement covering the sale of the Registrable
        Securities), the Company shall, at such time, promptly give each Holder
        written notice of such registration. Upon the written request of each
        Holder given within 20 days after the mailing of such notice by the
        Company, the Company shall, subject to the provisions of subsection
        1.3(b), cause to be registered under the Securities Act all of the
        Registrable Securities that each such Holder has requested to be
        registered.
 
             (b) In connection with any offering involving an underwriting of
        shares being issued by the Company, the Company shall not be required
        under this Section 1.3 to include any of the Holders' securities in such
        underwriting unless they accept the terms of the underwriting as agreed
        upon between the Company and the underwriters selected by it (or by
        other persons entitled to select the underwriters), and then only in
        such quantity as will not, in the opinion of the underwriters,
        jeopardize the success of the offering by the Company. If the total
        amount of securities, including Registrable Securities, requested by
        stockholders to be included in such offering exceeds the amount of
        securities that the underwriters reasonably believe compatible with the
        success of the offering, then the Company will include in such
        registration (i) first, if the registration pursuant to this Section 1.3
        was initiated by Other Holders exercising demand registration rights,
        100% of the securities such Other Holders propose to sell (except to the
        extent the terms of such Other Holders' registration rights provide
        otherwise); (ii) second, 100% of the securities the Company proposes to
        sell for its own account; (iii) third, to the extent that the number of
        securities which such Other Holders exercising demand registration
        rights and the Company propose to sell is less than the number of
        securities which the Company has been advised can be sold in such
        offering without having the adverse effect referred to above, such
        number of Registrable Securities which the Holders have requested to be
        included in such registration pursuant to Section 1.3 hereof and which,
        in the opinion of such managing underwriter(s), can be sold without
        having the adverse effect referred to above; and (iv) fourth, to the
        extent that the number of securities which are to be included in such
        registration pursuant to clauses (i), (ii) and (iii) is, in the
        aggregate, less than the number of securities which the Company has been
        advised can be sold in such offering without having the adverse effect
        referred to above, such number of other securities requested to be
        included in the offering for the account of any Other Holders which, in
        the opinion of such managing underwriter(s), can be sold without having
        the adverse effect referred to above.
 
          1.4  Obligations of the Company.
 
          Whenever required under this Section 1 to effect the registration of
     any Registrable Securities, the Company shall, as expeditiously as
     reasonably possible:
 
             (a) Prepare and file with the Commission a registration statement
        with respect to such Registrable Securities and use all reasonable
        efforts to cause such registration statement to become effective, and,
        upon the request of the Holders of a majority of the Registrable
        Securities registered thereunder, keep such registration statement
        effective for a period (the "Effectiveness Period") of up to 120 days or
        until the distribution contemplated by the registration statement has
        been completed. In the event that, in the judgment of the Company, it is
        advisable to suspend use of the prospectus relating to such registration
        statement for a discrete period of time (a "Deferral Period") due to
        pending material corporate developments or similar material events that
        have not yet been publicly disclosed and as to which the Company
        believes public disclosure will be prejudicial to the
                                      AF-3
<PAGE>   214
 
        Company, the Company shall deliver a certified resolution of the Board
        of Directors of the Company, signed by a duly authorized officer of the
        Company, to each Holder, to the effect of the foregoing and, upon
        receipt of such certificate, such Holders agree not to dispose of such
        Holders' Registrable Securities covered by such registration or
        prospectus (other than in transactions exempt from the registration
        requirements under the Securities Act); provided, however, that such
        Deferral Period shall be no longer than 75 days. The Effectiveness
        Period shall be extended for a period of time equal to such Deferral
        Period.
 
             (b) Prepare and file with the Commission such amendments and
        supplements to such registration statement and the prospectus used in
        connection with such registration statement as may be necessary to
        comply with the provisions of the Securities Act with respect to the
        disposition of all securities covered by such registration statement.
 
             (c) Furnish to the Holders of the Registrable Securities covered by
        such registration statement such numbers of copies of a prospectus,
        including a preliminary prospectus, and any amendment or supplement
        thereto and a reasonable number of copies of the then-effective
        registration statement and any post-effective amendment thereto, all in
        conformity with the requirements of the Securities Act, and such other
        documents as they may reasonably request in order to facilitate the
        disposition of such Registrable Securities.
 
             (d) Use all reasonable commercial efforts to register and qualify
        the securities covered by such registration statement under such other
        securities or Blue Sky laws of such jurisdictions as shall be reasonably
        requested by the Holders thereof; provided that the Company shall not be
        required in connection therewith or as a condition thereto to qualify to
        do business or to file a general consent to service of process in any
        such states or jurisdictions.
 
             (e) In the event of any underwritten public offering, enter into
        and perform its obligations under an underwriting agreement, in usual
        and customary form, with the managing underwriter of such offering. Each
        Holder participating in such underwriting shall also enter into and
        perform its obligations under such an agreement.
 
             (f) Notify each Holder of Registrable Securities covered by such
        registration statement, at any time when a prospectus relating thereto
        is required to be delivered under the Securities Act, of the happening
        of any event as a result of which the prospectus included in such
        registration statement, as then in effect, includes an untrue statement
        of a material fact or omits to state a material fact required to be
        stated therein or necessary to make the statements therein, in the light
        of the circumstances under which they were made, not misleading, and at
        the request of any such Holder prepare and furnish to such Holder a
        reasonable number of copies of a supplement or an amendment to such
        prospectus as may be necessary so that, as thereafter delivered to the
        purchasers of such Registrable Securities, such prospectus shall not
        include an untrue statement of a material fact or omit to state a
        material fact required to be stated therein or necessary to make the
        statements therein not misleading in the light of the circumstances then
        existing.
 
             (g) Furnish, at the request of any Holder requesting registration
        of Registrable Securities pursuant to this Section 1, on the date that
        such Registrable Securities are delivered to the underwriters for sale
        in connection with a registration pursuant to this Section 1, if such
        securities are being sold through underwriters, or, if such securities
        are not being sold through underwriters, on the date that the
        registration statement with respect to such securities becomes
        effective, (i) an opinion, dated such date, of the counsel representing
        the Company for the purposes of such registration, in form and substance
        as is customarily given to underwriters in an underwritten public
        offering, addressed to the underwriters, if any, and to the Holders
        requesting registration of Registrable Securities and (ii) in the case
        of an underwritten public offering a letter dated such date, from the
        independent certified public accountants of the Company, in form and
        substance as is customarily given by independent certified public
        accountants to underwriters in an underwritten public offering,
        addressed to the underwriters.
 
                                      AF-4
<PAGE>   215
 
             (h) Cause all Registrable Securities covered by the registration
        statement to be listed on each securities exchange or automated
        quotation system on which shares of Common Stock are then listed. If any
        of such shares are not so listed, the Company shall cause such shares to
        be listed on the securities exchange or automated quotation system as
        may be reasonably requested by the Holders of a majority of the
        Registrable Securities being registered.
 
             (i) Permit a single firm of counsel designated as selling
        stockholders' counsel by the holders of a majority in interest of the
        Registrable Securities to review, at the Holders' expense, the
        registration statement and all amendments and supplements thereto a
        reasonable period of time prior to their filing with the Commission and
        state authorities, and shall not file any document in a form to which
        such counsel reasonably objects.
 
             (j) Cause the Company's officers, directors and independent
        certified public accountants to supply all information reasonably
        requested by a representative of any Holder of Registrable Securities,
        and any attorney or accountant retained by such Holder, in connection
        with such registration; provided, however, that such representatives,
        attorneys or accountants of the Holders enter into a confidentiality
        agreement, in form and substance reasonably satisfactory to the Company,
        prior to the release or disclosure of any such information.
 
          1.5  Obligations of the Holders.
 
             (a) It shall be a condition precedent to the obligations of the
        Company to take any action pursuant to this Agreement that the selling
        Holders shall furnish to the Company such information regarding
        themselves, the Registrable Securities held by them, and the intended
        method of disposition of such securities as shall be required to effect
        the registration of the Registrable Securities. The Company shall have
        no obligation with respect to any registration requested pursuant to
        Section 1.2 of this Agreement if the number of shares of Registrable
        Securities to be included in the requested registration does not equal
        or exceed the number of shares required to trigger the Company's
        obligation to initiate such registration as specified in subsection
        1.2(a) above.
 
             (b) Upon the receipt by a Holder of any notice from the Company of
        (i) the existence of any fact or the happening of any event as a result
        of which the prospectus included in a registration statement filed
        pursuant to the terms hereof, as such registration statement is then in
        effect, includes an untrue statement of a material fact or omits to
        state a material fact required to be stated therein or necessary to make
        the statements therein, in the light of the circumstances under which
        they were made, not misleading, (ii) the issuance by the Commission of
        any stop order or injunction suspending or enjoining the use or the
        effectiveness of such registration statement or the initiation of any
        proceedings for that purpose, or the taking of any similar action by the
        securities regulators of any state or other jurisdiction, or (iii) the
        request by the Commission or any other federal or state governmental
        agency for amendments or supplements to such registration statement or
        related prospectus or for additional information related thereto, such
        Holder shall forthwith discontinue disposition of such Holder's
        Registrable Securities covered by such registration or prospectus (other
        than in transactions exempt from the registration requirements under the
        Securities Act) until such Holder's receipt of the supplemented or
        amended prospectus or until such Holder is advised in writing by the
        Company that the use of the applicable prospectus may be resumed. In
        such a case, the Effectiveness Period shall be extended by the number of
        days from and including the date of the giving of such notice to and
        including the date when each Holder shall have received a copy of the
        supplemented or amended prospectus or when such Holder is advised in
        writing by the Company that the use of the applicable prospectus may be
        resumed. The Company shall use all reasonable commercial efforts to
        limit the duration of any discontinuance of disposition of Registrable
        Securities pursuant to this section.
 
          1.6  Expenses.
 
             (a) Except as set forth herein, the Company shall bear and pay all
        expenses incurred in connection with any registration, filing or
        qualification of Registrable Securities with respect to the
 
                                      AF-5
<PAGE>   216
 
        registrations pursuant to Section 1.2 and 1.3 hereof, including (without
        limitation) all registration, filing and qualification fees, printers'
        and accounting fees relating or apportionable thereto, fees and
        disbursements of counsel for the Company, blue sky fees and expenses,
        including fees and disbursements of counsel related to all blue sky
        matters, fees and expenses of listing any Registrable Securities on any
        securities exchange or automated quotation system on which shares of
        Common Stock are then listed, the expenses of providing materials
        pursuant to Section 1.4 hereof, but excluding stock transfer taxes that
        may be payable by the selling Holders, and all underwriting discounts
        and commissions relating to Registrable Securities covered by such
        registration, which shall be borne by the Holders.
 
             (b) Notwithstanding subsection 1.6(a), the Company shall not be
        required to pay for any expenses of any registration proceeding begun
        pursuant to Section 1.2 if the registration request is subsequently
        withdrawn at the request of the Holders of a majority of the Registrable
        Securities to be registered (in which case all participating Holders
        shall bear such expenses), unless the Holders of a majority of the
        Registrable Securities agree to forfeit their right to one demand
        registration pursuant to Section 1.2; provided, however, that if such
        withdrawal occurs prior to the date the registration statement shall
        have become effective and as of the time of such withdrawal, such
        Holders have learned of a material adverse change in the business,
        properties, results of operations or financial condition of the Company
        from that known to such Holders at the time of their request and have
        withdrawn the request with reasonable promptness following disclosure by
        the Company of such material adverse change, then the Holders shall not
        be required to pay any of such expenses and shall retain their rights
        pursuant to Section 1.2.
 
          1.7  Delay of Registration.  No Holder shall have any right to obtain
     or seek an injunction restraining or otherwise delaying any such
     registration as the result of any controversy that might arise with respect
     to the interpretation or implementation of this Section 1.
 
          1.8  Indemnification.
 
          In the event any Registrable Securities are included in a registration
     statement under this Section 1:
 
             (a) To the extent permitted by law, the Company will indemnify and
        hold harmless each Holder of such Registrable Securities, the officers
        and directors of each such Holder, any underwriter (as defined in the
        Securities Act) for such Holder and each person, if any, who controls
        such Holder or underwriter within the meaning of the Securities Act or
        the Exchange Act, against any losses, claims, damages or liabilities
        (joint or several) to which they may become subject under the Securities
        Act, the Exchange Act or other federal or state law, insofar as such
        losses, claims, damages or liabilities (or actions in respect thereof)
        arise out of or are based upon any of the following statements,
        omissions or violations (collectively, a "Violation"): (i) any untrue
        statement or alleged untrue statement of a material fact contained in
        such registration statement, including any preliminary prospectus or
        final prospectus contained therein or any amendments or supplements
        thereto, (ii) the omission or alleged omission to state therein a
        material fact required to be stated therein, or necessary to make the
        statements therein not misleading, or (iii) any violation or alleged
        violation by the Company of the Securities Act, the Exchange Act, any
        state securities law or any rule or regulation promulgated under the
        Securities Act, the Exchange Act or any state securities law; and the
        Company will reimburse each such Holder, officer or director,
        underwriter or controlling person for any legal or other expenses
        reasonably incurred by them in connection with investigating or
        defending any such loss, claim, damage, liability or action; provided,
        however, that the indemnity agreement contained in this subsection
        1.8(a) shall not apply to amounts paid in settlement of any such loss,
        claim, damage, liability or action if such settlement is effected
        without the consent of the Company (which consent shall not be
        unreasonably withheld), nor shall the Company be liable in any such case
        for any such loss, claim, damage, liability or action to the extent that
        it arises out of or is based upon a Violation that occurs in reliance
        upon and in conformity with written information furnished expressly for
        use in connection with such registration by any such Holder, officer,
        director, underwriter or controlling person.
 
                                      AF-6
<PAGE>   217
 
             (b) To the extent permitted by law, each selling Holder will
        indemnify and hold harmless the Company, each of its directors, each of
        its officers who have signed the registration statement, each person, if
        any, who controls the Company within the meaning of the Securities Act,
        any underwriter and any other Holder selling securities in such
        registration statement or any of its directors or officers or any person
        who controls such Holder, against any losses, claims, damages or
        liabilities (joint or several) to which the Company or any such
        director, officer, controlling person, or underwriter or controlling
        person, or other such Holder or director, officer or controlling person
        may become subject, under the Securities Act, the Exchange Act or other
        federal or state law, insofar as such losses, claims, damages or
        liabilities (or actions in respect thereto) arise out of or are based
        upon any Violation, in each case to the extent (and only to the extent)
        that such Violation occurs in reliance upon and in conformity with
        written information furnished by such Holder expressly for use in
        connection with such registration; and each such Holder will reimburse
        any legal or other expenses reasonably incurred by the Company or any
        such director, officer, controlling person, underwriter or controlling
        person, other Holder, officer, director, or controlling person in
        connection with investigating or defending any such loss, claim, damage,
        liability, or action; provided, however, that the indemnity agreement
        contained in this subsection 1.8(b) shall not apply to amounts paid in
        settlement of any such loss, claim, damage, liability or action if such
        settlement is effected without the consent of the Holder, which consent
        shall not be unreasonably withheld; provided, that, in no event shall
        any indemnity under this subsection 1.8(b) exceed the net proceeds from
        the sale of the Registrable Securities received by such Holder.
 
             (c) Promptly after receipt by an indemnified party under this
        Section 1.8 of notice of the commencement of any action (including any
        governmental action), such indemnified party will, if a claim in respect
        thereof is to be made against any indemnifying party under this Section
        1.8, deliver to the indemnifying party a written notice of the
        commencement thereof and the indemnifying party shall have the right to
        participate in, and, to the extent the indemnifying party so desires,
        jointly with any other indemnifying party similarly noticed, to assume
        the defense thereof with counsel mutually satisfactory to the parties;
        provided, however, that an indemnified party (together with all other
        indemnified parties which may be represented without conflict by one
        counsel) shall have the right to retain one separate counsel, with the
        fees and expenses to be paid by the indemnifying party, if
        representation of such indemnified party by the counsel retained by the
        indemnifying party would be inappropriate due to actual or potential
        differing interests between such indemnified party and any other party
        represented by such counsel in such proceeding. The failure to deliver
        written notice to the indemnifying party within a reasonable time of the
        commencement of any such action, if prejudicial to its ability to defend
        such action, shall relieve such indemnifying party of any liability to
        the indemnified party under this Section 1.8 to the extent the
        indemnifying party was actually damaged or suffered any loss or incurred
        any additional expense as a result thereof, but the omission so to
        deliver written notice to the indemnifying party will not relieve it of
        any liability that it may have to any indemnified party otherwise than
        under this Section 1.8. An indemnifying party shall not, without the
        prior written consent of the indemnified parties, settle, compromise or
        consent to the entry of any judgment with respect to any pending or
        threatened claim, action, suit or proceeding in respect of which
        indemnification may be sought hereunder by such indemnified parties
        (whether or not the indemnified parties are actual or potential parties
        to such claim or action) unless such settlement, compromise or consent
        includes a release of such indemnified party reasonably acceptable to
        such indemnified party from all liability arising out of such claim,
        action, suit or proceeding.
 
             (d) If the indemnification provided for in this Section 1.8 is held
        by a court of competent jurisdiction to be unavailable to an indemnified
        party with respect to any loss, liability, claim, damage, or expense
        referred to therein, then the indemnifying party, in lieu of
        indemnifying such indemnified party hereunder, shall contribute to the
        amount paid or payable by such indemnified party as a result of such
        loss, liability, claim, damage, or expense in such proportion as is
        appropriate to reflect the relative fault of the indemnifying party on
        the one hand and of the indemnified party on the other in connection
        with the statements or omissions that resulted in such loss, liability,
        claim,
                                      AF-7
<PAGE>   218
 
        damage, or expense as well as any other relevant equitable
        considerations. The relative fault of the indemnifying party and of the
        indemnified party shall be determined by reference to, among other
        things, whether the untrue or alleged untrue statement of a material
        fact or the omission to state a material fact relates to information
        supplied by the indemnifying party or by the indemnified party and the
        parties' relative intent, knowledge, access to information, and
        opportunity to correct or prevent such statement or omission.
 
             (e) Notwithstanding the foregoing, to the extent that the
        provisions on indemnification and contribution contained in the
        underwriting agreement entered into in connection with the underwritten
        public offering are in conflict with the foregoing provisions, the
        provisions in the underwriting agreement shall control.
 
             (f) The obligations of the Company and Holders under this Section
        1.8 shall survive the completion of any offering of Registrable
        Securities in a registration statement under this Section 1, and
        otherwise.
 
          1.9  Assignment of Registration Rights.  The rights to cause the
     Company to register Registrable Securities pursuant to this Section 1 may
     be transferred or assigned by a Holder, in whole or in part, without any
     prior written consent of the Company, to (a) a wholly-owned subsidiary of
     the Holder or a successor to substantially all the business or assets of
     the Holder or (b) a transferee or assignee of 10% or more of the then
     outstanding Registrable Securities; provided that the Company is, within a
     reasonable time after such transfer or assignment, furnished with written
     notice of the name and address of such transferee or assignee and the
     securities with respect to which such registration rights are being
     transferred or assigned; and provided, further, that the transferee or
     assignee of such rights assumes in writing the obligations of such Holder
     under this Section 1.
 
          1.10  Reports Under the Exchange Act.  With a view to making available
     to the Holders the benefits of Rule 144 under the Securities Act and any
     other rule or regulation of the Commission that may at any time permit a
     Holder to sell securities of the Company to the public without
     registration, the Company agrees to:

                       IRREVOCABLE PROXY/VOTING AGREEMENT
 
     THIS IRREVOCABLE PROXY/VOTING AGREEMENT (this "Agreement") dated as of
December 2, 1998, among SCANSOFT, INC., a Delaware corporation ("ScanSoft"), on
the one hand, and certain stockholders of VISIONEER, INC., a Delaware
corporation ("Visioneer"), listed on Schedule A hereto (each a "Stockholder"
and, collectively, the "Stockholders"), on the other hand,
 
                                  WITNESSETH:
 
     WHEREAS, ScanSoft and Visioneer propose to enter into an Agreement and Plan
of Merger dated as of the date hereof (as the same may be amended or
supplemented, the "Merger Agreement"; capitalized terms used but not defined
herein shall have the meanings set forth in the Merger Agreement) providing that
ScanSoft shall merge with and into Visioneer (the "Merger") upon the terms and
subject to the conditions set forth in the Merger Agreement;
 
     WHEREAS, each Stockholder owns beneficially or of record the number of
shares of Visioneer Common Stock, par value $0.001 per share, of Visioneer (the
"Visioneer Common Stock") set forth opposite its name on Schedule A attached
hereto (the "Subject Shares");
 
     WHEREAS, as a condition to its willingness to enter into the Merger
Agreement, ScanSoft has required that each Stockholder enter into this
Agreement.
 
     NOW, THEREFORE, to induce ScanSoft to enter into, and in consideration of
its entering into, the Merger Agreement, and in consideration of the premises
and the representations, warranties and agreements contained herein, the parties
agree as follows:
 
          1.  Representations and Warranties of Each Stockholder.  Each
     Stockholder hereby, severally and not jointly, represents and warrants to
     ScanSoft as of the date hereof in respect of itself as follows:
 
             (a) Authority.  The Stockholder has all requisite power and
        authority to enter into this Agreement and to consummate the
        transactions contemplated hereby. This Agreement has been duly
        authorized, executed and delivered by the Stockholder and constitutes a
        valid and binding obligation of the Stockholder enforceable in
        accordance with its terms, except that such enforceability (i) may be
        limited by bankruptcy, insolvency, moratorium or other similar laws
        affecting or relating to the enforcement of creditors' rights generally
        and (ii) is subject to general principles of equity. The execution and
        delivery of this Agreement does not, and the consummation of the
        transactions contemplated hereby and compliance with the terms hereof
        will not, conflict with, or result in any violation of, or default (with
        or without notice or lapse of time or both) under any provision of, any
        trust agreement, loan or credit agreement, note, bond, mortgage,
        indenture, lease or other agreement, instrument, permit, concession,
        franchise, license, judgment, order, notice, decree, statute, law,
        ordinance, rule or regulation applicable to the Stockholder or to the
        Stockholder's property or assets the effect of which, in any case, would
        be material and adverse to the ability of the Stockholder to consummate
        the transactions contemplated hereby or to comply with the terms hereof.
 
             (b) The Subject Shares.  The Stockholder is the record and
        beneficial owner of and has the sole right to vote the Subject Shares
        set forth opposite such Stockholder's name on Schedule A attached
        hereto. None of such Subject Shares is subject to any voting trust or
        other agreement, arrangement or restriction, except as contemplated by
        this Agreement.
 
          2.  Covenants of Each Stockholder.  Until the termination of this
     Agreement in accordance with Section 6, each Stockholder, severally and not
     jointly, agrees as follows:
 
             (a) Vote for the Merger.  At any meeting of stockholders of
        Visioneer called to vote upon the Merger and the Merger Agreement or at
        any adjournment thereof or in any other circumstances
 
                                       B-1
<PAGE>   222
 
        upon which a vote, consent or other approval (including by written
        consent) with respect to the Merger and the Merger Agreement is sought,
        the Stockholder shall vote (or cause to be voted), or execute a written
        consent in respect of, the Subject Shares in favor of the Merger, the
        adoption by Visioneer of the Merger Agreement and the approval of the
        terms thereof and each of the other transactions contemplated by the
        Merger Agreement. Each Stockholder hereby waives any appraisal rights
        granted pursuant to Section 262 of the General Corporation Law of the
        State of Delaware (the "DGCL") (or any successor provision) to which it
        may otherwise be entitled as a result of the Merger or the other
        transactions contemplated by the Merger Agreement.
 
             (b) Vote Against Alternative Proposals.  At any meeting of
        stockholders of Visioneer or at any adjournment thereof or in any other
        circumstances upon which the stockholders' vote, consent or other
        approval is sought, the Stockholders shall be present (in person or by
        proxy) and shall vote (or cause to be voted) the Subject Shares against
        (i) any merger agreement or merger (other than the Merger Agreement and
        the Merger), consolidation, combination, sale of substantial assets
        (other than the Asset Purchase Agreement), reorganization,
        recapitalization, dissolution, liquidation or winding up of or involving
        Visioneer or (ii) any amendment of Visioneer's certificate of
        incorporation or by-laws or other proposal or transaction involving
        Visioneer or any of its subsidiaries, which amendment or other proposal
        or transaction would in any manner impede, frustrate, prevent, delay or
        nullify the Merger, the Merger Agreement or any of the other
        transactions contemplated by the Merger Agreement or change in any
        manner the voting rights of any class of capital stock of Visioneer.
        Each Stockholder further agrees not to commit or agree to take any
        action inconsistent with the foregoing.
 
             (c) No Transfer of Subject Shares.  Each Stockholder agrees not to
        (i) convert, transfer, sell, pledge, assign or otherwise dispose of
        (including by gift) (collectively, "Transfer"), or enter into any
        contract, option or other arrangement (including any profit sharing
        arrangement) with respect to the Transfer of, any of the Subject Shares
        to any person other than pursuant to the terms of the Merger or (ii)
        enter into any voting arrangement, whether by proxy, power-of-attorney,
        voting agreement, voting trust or otherwise. Notwithstanding the
        foregoing, each Stockholder may Transfer Subject Shares if the proposed
        transferee agrees to be bound by all of the terms of this Agreement and
        delivers a written instrument to ScanSoft evidencing such agreement
        prior to the date of the proposed Transfer.
 
             (d) No Solicitation.  During the terms of this Agreement, each
        Stockholder shall not, nor shall they permit any of their Affiliates or
        any director, officer, employee, investment banker, attorney or other
        advisor or representative of any of the foregoing to, (i) directly or
        indirectly, solicit, initiate or knowingly encourage the submission of,
        any Takeover Proposal (as defined in the Merger Agreement) related to or
        involving Visioneer or (ii) except as set forth in Section 8 of this
        Agreement, directly or indirectly participate in any discussions or
        negotiations regarding, or furnish to any person any information with
        respect to, or knowingly take any other action to facilitate any
        inquires or the making of any proposal that constitutes, or may
        reasonably be expected to lead to, any Takeover Proposal related to or
        involving Visioneer.
 
        3.  Grant of Irrevocable Proxy.
 
             (a) Existing Proxies Revoked.  Each Stockholder hereby represents
        that any proxies heretofore given in respect of the Subject Shares are
        not irrevocable, and that any such proxies are hereby revoked.
 
             (b) Grant of Irrevocable Proxy to ScanSoft.  Each Stockholder
        hereby agrees that, in the event Stockholder shall fail to comply with
        the provisions of Sections 2(a) and 2(b) hereof, as determined by
        ScanSoft in its sole discretion, such failure shall result, without any
        further action by Stockholder, in the irrevocable appointment of
        ScanSoft, and any person or persons who may hereafter be designated by
        ScanSoft as permitted under applicable law, and each of such person(s)
        individually, as the Stockholder's proxy and attorney-in-fact (with full
        power of substitution), for and in the name, place and stead of the
        Stockholder, to vote the Subject Shares, or grant a consent
                                       B-2
<PAGE>   223
 
        or approval in respect of such Subject Shares, in favor of or against,
        as the case may be, the matters set forth in Sections 2(a) and 2(b). The
        proxy granted hereby shall terminate upon any termination of this
        Agreement in accordance with its terms.
 
             (c) Affirmations.  Each Stockholder hereby affirms that any
        irrevocable proxy granted pursuant to Section 3(b) will be given in
        connection with the execution of the Merger Agreement, and that such
        irrevocable proxy will be given to secure the performance of the duties
        of the Stockholders under this Agreement. If so granted, the
        Stockholders hereby ratify and confirm all that such irrevocable proxy
        may lawfully do or cause to be done by virtue thereof. This proxy and
        power of attorney is irrevocable and coupled with an interest and is
        intended to be irrevocable in accordance with the provisions of Section
        212(e) of the DGCL.
 
          4.  Further Assurances.  Each Stockholder will, from time to time,
     execute and deliver, or cause to be executed and delivered, such additional
     or further consents, documents and other instruments as ScanSoft may
     reasonably request for the purpose of effectively carrying out the
     transactions contemplated by this Agreement.
 
          5.  Assignment.  Except as provided herein, neither this Agreement nor
     any of the rights, interests or obligations hereunder shall be assigned by
     any of the parties hereto without the prior written consent of the other
     parties. Subject to the preceding sentence, this Agreement will be binding
     upon, inure to the benefit of and be enforceable by the parties and their
     respective successors and assigns.
 
          6.  Termination.  This Agreement shall terminate as follows: (i) if
     the transactions contemplated by the Merger Agreement are consummated, this
     Agreement shall terminate upon the Effective Time of the Merger; (ii) if

     the Merger Agreement; or (iv) notwithstanding anything in this Section 6 to
     the contrary, if the Company receives and publicly announces any Takeover
     Proposal prior to the date of termination of the Merger Agreement and the
     transactions contemplated by the Merger Agreement are not consummated and
     the Merger Agreement is terminated for any reason, this Agreement shall
     terminate upon the later of (A) the six (6) month anniversary of the date
     of termination of the Merger Agreement or (B) one month following the date

        the subject matter hereof and (ii) is not intended to confer upon any
        person other than the parties hereto, any rights or remedies hereunder.
 
             (f) Governing Law.  This 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 law thereof.
 
             (g) Severability.  If any term, provision, covenant or restriction
        herein, or the application thereof to any circumstance, shall, to any
        extent, be held by a court of competent jurisdiction to be invalid, void
        or unenforceable, the remainder of the terms, provisions, covenants and
        restrictions herein and the application thereof to any other
        circumstances, shall remain in full force and effect, shall not in any
        way be affected, impaired or invalidated, and shall be enforced to the
        fullest extent permitted by law, and the parties hereto shall reasonably
        negotiate in good faith a substitute term or provision that comes as
        close as possible to the invalidated and unenforceable term or
        provision, and that puts each party in a position as nearly comparable
        as possible to the position each such party would have been in but for
        the finding of invalidity or unenforceability, while remaining valid and
        enforceable.
 
          8.  Stockholder Representatives.  Each Stockholder signs solely in its
     capacity as the record holder and/or beneficial owner of such Stockholder's
     Subject Shares and nothing contained herein shall limit or affect any
     actions taken by any officer, director, partner, trustee, affiliate or
     representative of a Stockholder who is or becomes an officer or a director
     of Visioneer or serves Visioneer in any other fiduciary capacity in his or
     her capacity as an officer, director or other fiduciary of Visioneer and
     none of such actions in such capacity shall be deemed to constitute a
     breach of this Agreement.
 
          9.  Enforcement.  The parties agree that irreparable damage would
     occur in the event that any of the provisions of this Agreement were not
     performed in accordance with their specific terms or were otherwise
     breached. It is accordingly agreed that the parties shall be entitled to an
     injunction or injunctions to prevent breaches of this Agreement and to
     enforce specifically the terms and provisions of this Agreement in any
     court of the United States located in the State of Delaware or in a
     Delaware state court, this being in addition to any other remedy to which
     they are entitled at law or in equity. In addition, each of the parties
     hereto (i) consents to submit such party to the personal jurisdiction of
     any Federal court located in the State of Delaware or any Delaware state
     court in the event any dispute arises out of this Agreement or any of the
     transactions contemplated hereby, (ii) agrees that such party will not
     attempt to deny or defeat such personal jurisdiction by motion or other
     request for leave from any such court, (iii) agrees that such party will
     not bring any action relating to this Agreement or the transactions
     contemplated hereby in any court other than a Federal court sitting in the
     state of Delaware or a Delaware state court, (iv) waives any right to trial
     by jury with respect to any claim or proceeding related to or arising out
     of this Agreement or any of the transactions contemplated hereby, and (v)
     appoints The Corporation Trust Company as such party's agent for service of
     process in the state of Delaware.

                                  CONFIDENTIAL
 
Board of Directors
Visioneer, Inc.
34800 Campus Drive
Fremont, CA 94555
 
Dear Members of the Board:
 
     We understand that Visioneer, Inc. ("Visioneer") and ScanSoft, Inc.
("ScanSoft"), a subsidiary of Xerox Corporation ("Xerox"), propose to enter into
an Agreement and Plan of Merger (the "Agreement") pursuant to which, through the
merger of ScanSoft and Visioneer (the "Merger") with Visioneer surviving as the
surviving corporation (as such, the "Surviving Corporation"), the shares of
Visioneer common stock ("Visioneer Common Stock") outstanding immediately prior
to the Merger will be converted as follows: (i) 5,079,000 shares will be
converted into the right to receive $2.06 per share in cash ("Cash
Consideration") and (ii) each remaining share will be converted into the right
to receive one share of common stock of the Surviving Corporation ("Surviving
Corporation Common Stock") ("Stock Consideration"), subject to pro-rata
adjustment in the manner provided in the Agreement (in aggregate, the
"Consideration"). Upon consummation of the Merger, former holders of the
Visioneer Common Stock will own approximately 46.2% of the total number of
shares of Surviving Corporation Common Stock outstanding immediately following
the Merger on a fully-diluted basis, and the remainder (i.e., 53.8%) will be
held by the holders of ScanSoft common stock and other ScanSoft securities
outstanding immediately prior to the Merger through the issuance of shares of
Surviving Corporation Common Stock, Surviving Corporation preferred stock and
options to purchase additional shares of Surviving Corporation Common Stock to
such former holders of ScanSoft securities.
 
     The Merger is conditioned on, among other things, Visioneer consummating
the sale of its Hardware Division (as defined in the Agreement) to a third party
in accordance with the terms of the Asset Purchase Agreement (as defined in the
Agreement). The Merger is intended to be treated as a tax-free reorganization
pursuant to the provisions of section 368 of the 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 Consideration to be
received in the Merger is fair, from a financial point of view, to Visioneer
shareholders.
 
     Broadview International LLC focuses on providing merger and acquisition
advisory services to information technology ("IT") companies. In this capacity,
we are continually engaged in valuing such businesses, and we maintain an
extensive database of IT mergers and acquisitions for comparative purposes. We
are currently acting as financial advisor to Visioneer's Board of Directors and
will receive a fee from Visioneer upon the successful conclusion of the Merger.
 
     In rendering our opinion, we have, among other things:
 
          (1) reviewed the terms of the Agreement and the associated exhibits
     thereto dated November 23, 1998 furnished to us by Xerox's legal advisors
     on November 24, 1998 (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);
 
          (2) reviewed the terms of the Asset Purchase Agreement and the
     associated exhibits thereto furnished to us by Visioneer's legal advisors
     on November 11, 1998 (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);

     rationale for the Merger;

     with public companies we deemed comparable;
 
          (9) reviewed Xerox's annual report and Form 10-K for the fiscal year
     ended December 31, 1997, including the audited financial statements
     included therein, Xerox's Forms 10-Q and 10-QA for its quarterly period
     ended September 30, 1998, including the unaudited financial statements
     included therein;
 
          (10) reviewed ScanSoft's unaudited quarterly income statements for the
     fiscal year ended December 31, 1997 and ScanSoft's unaudited quarterly
     income statements for the nine months ended September 30, 1998, prepared by
     ScanSoft management and furnished to us by Xerox's financial advisors;
 
          (11) reviewed certain internal financial and operating information,
     including projections through December 31, 1999, relating to ScanSoft
     prepared by ScanSoft management and furnished to us by Xerox's financial
     advisors;
 
          (12) reviewed Visioneer management due diligence findings regarding
     ScanSoft's business;
 
          (13) participated in discussions with ScanSoft management concerning
     the operations, business strategy, financial performance and prospects for
     ScanSoft;
 
          (14) discussed with ScanSoft management its view of the strategic
     rationale for the Merger;
 
          (15) compared certain aspects of the projected financial performance
     of the Surviving Corporation with public companies we deemed comparable;
 
          (16) 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
 
          (17) reviewed recent equity analyst reports covering Visioneer and
     Xerox;
 
          (18) reviewed projections through December 31, 2003 for the Surviving
     Corporation prepared by ScanSoft management and provided to us by Xerox's
     financial advisors;
 
          (19) reviewed preliminary correspondence and discussed issues with
     Visioneer management and the Company's tax and accounting advisors
     regarding the accounting treatment of the transaction and a potential
     written opinion by the Securities and Exchange Commission;
 
          (20) participated in negotiations and discussions related to the
     Merger among Visioneer, ScanSoft and their financial and legal advisors;
     and
 
          (21) 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
 
                                       C-2
<PAGE>   232
 
warranties contained in the Agreement and the unaudited financials of ScanSoft)
that was publicly available or furnished to us by Visioneer, ScanSoft, or
Xerox's financial advisor. 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 Visioneer and
ScanSoft as to the future performance of Visioneer, ScanSoft and the Surviving
Corporation, as applicable. We have neither made nor obtained an independent
appraisal or valuation of any of Visioneer's or ScanSoft's assets. We have also
assumed that the Asset Purchase Agreement will have been consummated in
accordance with its terms prior to or contemporaneously with the consummation of
the Merger. We have also assumed that the Merger will be accounted for as a
purchase transaction under the United States Generally Accepted Accounting
Principles, whereby Visioneer is considered the buyer.
 
     Based upon and subject to the foregoing, we are of the opinion that the
Consideration to be received in the Merger is fair, from a financial point of
view, to Visioneer shareholders.
 
     The foregoing opinion relates to the aggregate consideration to be received
by Visioneer shareholders in the Merger, and no opinion is rendered herein with
respect to the allocation of the Consideration among Visioneer shareholders.
Such allocation is to be determined by elections made by Visioneer shareholders
as to whether to receive Cash Consideration or Stock Consideration, and may be
adjusted in accordance with the terms of the Agreement.
 
     For purposes of this opinion, we have assumed that neither Visioneer nor
ScanSoft is currently involved in any material transaction other than the
following: the Merger, other transactions of which we are aware (including those
relating to the Asset Purchase Agreement), 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 may impact this opinion. We express no opinion as to the price
at which the Surviving Corporation Common Stock will trade at any time.
 
     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 Visioneer in
connection with its consideration of the Merger and does not constitute a
recommendation to any Visioneer shareholder as to how such shareholder 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 International LLC hereby consents to references to and the
inclusion of this opinion in its entirety in the Proxy Statement/Prospectus to
be distributed to Visioneer shareholders in connection with the Merger.
 
                                          Sincerely,
 
                                          /s/ BROADVIEW INTERNATIONAL LLC

                               SECTION 262 OF THE
                        DELAWARE GENERAL CORPORATION LAW
 
     APPRAISAL RIGHTS. (a) Any stockholder of a corporation of this State who
holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to Section 228 of this title shall be entitled to an appraisal by the
Court of Chancery of the fair value of his shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Sections 251 (other than a merger effected pursuant to
subsection (g) of section 251), 252, 254, 257, 258, 263 or 264 of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the holders of the surviving corporation as
     provided in subsection (f) of Section 251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     Sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;
 
             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock or depository receipts at the
        effective date of the merger or consolidation will be either listed on a
        national securities exchange or designated as a national market system
        security on an interdealer quotation system by the National Association
        of Securities Dealers, Inc. or held of record by more than 2,000
        holders;
 
             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or
 
             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under Section 253 of this title is not owned by
     the parent corporation immediately prior to the merger, appraisal rights
     shall be available for the shares of the subsidiary Delaware corporation.
 
                                       D-1
<PAGE>   234
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to Section
     228 or Section 253 of this title, each constituent corporation, either
     before the effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within twenty days after the date of
     mailing of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given; provided that,
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given
 
                                       D-2
<PAGE>   235
 
     prior to the effective date, the record date shall be the close of business
     on the day next preceding the day on which the notice is given.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by one or more publications at
least one week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or
 
                                       D-3
<PAGE>   236
 
compound, as the Court may direct. Payment shall be so made to each such
stockholder, in the case of holders of uncertificated stock forthwith, and the
case of holders of shares represented by certificates upon the surrender to the
corporation of the certificates representing such stock. The Court's decree may
be enforced as other decrees in the Court of Chancery may be enforced, whether
such surviving or resulting corporation be a corporation of this State or of any
state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

Stock authorized by this Amended and Restated Certificate of Incorporation may
be issued from time to time in one or more series. The first series of Preferred
Stock shall be designated "Series B Preferred Stock" and shall consist of

wholly unissued series of Preferred Stock, within the limitations and
restrictions stated in this Amended and Restated Certificate of Incorporation,
to fix or alter the dividend rights, dividend rate, conversion rights, voting
rights, rights and terms of redemption (including sinking fund provisions), the
redemption price or prices, and the liquidation preferences of any wholly
unissued series of Preferred Stock, and the number of shares constituting any
such series and the designation thereof, or any of them, and to increase or
decrease the number of shares of any series subsequent to the issue of shares of
that series, but not below the number of shares of such series then outstanding.
In case the number of shares of any
 
                                       E-1
<PAGE>   238
 
series shall be so decreased, the shares constituting such decrease shall resume
the status that they had prior to the adoption of the resolution originally
fixing the number of shares of such series.
 
     1. Dividend Provisions.
 
          (a) The holders of shares of Series B Preferred Stock shall be
     entitled to receive dividends, out of any assets legally available
     therefor, prior and in preference to any declaration or payment of any
     dividend (payable other than in Common Stock or other securities and rights
     convertible into or entitling the holder thereof to receive, directly or
     indirectly, shares of Common Stock of this corporation) on the Common Stock
     of this corporation, at the rate of $0.065 per share of Series B Preferred
     Stock per annum (as determined on a per annum basis and an as converted
     basis for the Series B Preferred Stock) whenever funds are legally
     available therefor, payable when, as and if declared by the Board of
     Directors. Such dividends shall be non-cumulative. Unless full dividends on
     the Series B Preferred Stock for the then current dividend period shall
     have been paid or declared and a sum sufficient for the payment thereof set
     apart: (i) no dividend whatsoever (other than a dividend payable solely in
     Common Stock or other securities and rights convertible into or entitling
     the holder thereof to receive, directly or indirectly, additional shares of
     Common Stock of this corporation) shall be paid or declared, and no
     distribution shall be made, on any Common Stock. Dividends, if declared,
     must be declared and paid with respect to all series of Preferred Stock
     contemporaneously, and if less than full dividends are declared, the same
     percentage of the dividend rate will be payable to each series of Preferred
     Stock.
 
          (b) After payment of such dividends, any additional dividends or
     distributions shall be distributed among all holders of Common Stock and
     all holders of Series B Preferred Stock in proportion to the number of
     shares of Common Stock which would be held by each such holder if all
     shares of Series B Preferred Stock were converted to Common Stock at the
     then effective conversion rate.
 
     2. Liquidation Preference.
 
          (a) In the event of any liquidation, dissolution or winding up of this
     corporation, either voluntary or involuntary, the holders of Series B
     Preferred Stock shall be entitled to receive, prior and in preference to
     any distribution of any of the assets of this corporation to the holders of
     Common Stock by reason of their ownership thereof, an amount per share
     equal to (i) $1.30 for each outstanding share of Series B Preferred Stock
     (the "Original Series B Issue Price") plus an amount equal to all declared
     but unpaid dividends on each such share. If upon the occurrence of such
     event, the assets and funds thus distributed among the holders of the
     Series B Preferred Stock shall be insufficient to permit the payment to
     such holders of the full aforesaid preferential amounts, then the entire
     assets and funds of this corporation legally available for distribution
     shall be distributed ratably among the holders of the Series B Preferred
     Stock in proportion to the product of the liquidation preference of each
     such share and the number of such shares owned by each such holder.
 
          (b) After the distribution described in section (a) above has been
     paid, the remaining assets of this corporation available for distribution
     to stockholders shall be distributed among the holders of Common Stock pro
     rata based on the number of shares of Common Stock held by each.
 
     3. No Redemption. No holder of Series B Preferred Stock shall have any
right to require the corporation or any "related person" (within the meaning of
section 351(g)(3)(B) of the Internal Revenue Code) to redeem or purchase any
shares of Series B Preferred Stock. Similarly, neither the corporation nor any
such related person shall have any right or option to redeem or purchase any
shares of Series B Preferred Stock from any holder thereof.
 
     4. Conversion. The holders of Series B Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):
 
          (a) Right to Convert; Automatic Conversion.
 
             (i) Subject to subsection (c), each share of Series B Preferred
        Stock shall be convertible, at the option of the holder thereof, during
        the periods specified in Section 4(a)(ii) below, at the office of this
        corporation or any transfer agent for the Series B Preferred Stock, into
        such number of fully
                                       E-2
<PAGE>   239
 
        paid and nonassessable shares of Common Stock as is determined by
        dividing the Original Series B Issue Price by the Conversion Price
        applicable to such shares in effect on the date the certificate for such
        share is surrendered for conversion. The initial Conversion Price per
        share for shares of Series B Preferred Stock shall be the Original
        Series B Issue Price; provided, however, that the Conversion Price for
        shares of Series B Preferred Stock shall be subject to adjustment as set
        forth in subsection 4(c) below.
 
             (ii) The shares of Series B Preferred Stock shall not be
        convertible into Common Stock prior to             , 2001; provided,
        however, that notwithstanding the foregoing, each share of Series B
        Preferred Stock shall be convertible into Common Stock, at the option of
        the holder thereof, at any time after the date on which such holder owns
        directly or indirectly a number of outstanding shares of Common Stock of
        this corporation that represents less than 30.0% of the total number of
        shares of Common Stock outstanding immediately prior to conversion of
        such share; and provided further, however, that such holder shall not be
        entitled to convert any share of Series B Preferred Stock pursuant to
        this Section 4(a)(ii) if the conversion of such share to Common Stock
        would result in such holder owning directly or indirectly a number of
        outstanding shares of Common Stock of this corporation that represents
        more than 50.0% of the total number of shares of Common Stock
        outstanding immediately after the conversion of such share.
 
             (iii) At any time after             , 2001, upon the written
        consent of the holders of at least 66 2/3% of the then outstanding
        shares of Series B Preferred Stock, each share of Series B Preferred
        Stock shall automatically and immediately be converted into such number
        of fully paid and nonassessable shares of Common Stock as is determined
        by dividing the Original Series B Issue Price by the Conversion Price
        applicable to such shares in effect on the date the certificate for such
        share is surrendered for conversion. The initial Conversion Price per
        share for shares of Series B Preferred Stock shall be the Original
        Series B Issue Price; provided, however, that the Conversion Price for
        shares of Series B Preferred Stock shall be subject to adjustment as set
        forth in subsection 4(c) below.
 
          (b) Mechanics of Conversion. Before any holder of shares of Series B
     Preferred Stock shall be entitled to convert the same into shares of Common
     Stock, such holder shall surrender the certificate or certificates
     therefor, duly endorsed, at the office of this corporation or of any
     transfer agent for such Series B Preferred Stock, and shall give written
     notice by mail, postage prepaid, to this corporation at its principal
     corporate office, of the election to convert the same and shall state
     therein the name or names in which the certificate or certificates for
     shares of Common Stock are to be issued. This corporation shall, as soon as
     practicable thereafter, issue and deliver at such office to such holder of
     Series B Preferred Stock, or to the nominee or nominees of such holder, a
     certificate or certificates for the number of shares of Common Stock to
     which such holder shall be entitled as aforesaid. Such conversion shall be
     deemed to have been made immediately prior to the close of business on the
     date of such surrender of the shares of Series B Preferred Stock to be
     converted, and the person or persons entitled to receive the shares of
     Common Stock issuable upon such conversion shall be treated for all
     purposes as the record holder or holders of such shares of Common Stock as
     of such date. If the conversion is in connection with an underwritten
     offering of securities registered pursuant to the Securities Act of 1933,
     as amended, the conversion may, at the option of any holder tendering
     Series B Preferred Stock for conversion, be conditioned upon the closing
     with the underwriter(s) of the sale of securities pursuant to such
     offering, in which event the person(s) entitled to receive the Common Stock
     issuable upon such conversion of shares of Series B Preferred Stock shall
     not be deemed to have converted such shares of Series B Preferred Stock
     until immediately prior to the closing of such sale of securities.
 
          (c) Conversion Price Adjustments of Series B Preferred Stock. The
     Conversion Price of the Series B Preferred Stock shall be subject to
     adjustment from time to time as follows:
 
             (i) In the event this corporation should at any time or from time
        to time after the date upon which any shares of Series B Preferred Stock
        were initially issued (a "Purchase Date") fix a record date for the
        effectuation of a split or subdivision of the outstanding shares of
        Common Stock or the
 
                                       E-3
<PAGE>   240
 
        determination of holders of Common Stock entitled to receive a dividend
        or other distribution payable in additional shares of Common Stock or
        other securities or rights convertible into, or entitling the holder
        thereof to receive directly or indirectly, additional shares of Common
        Stock (hereinafter referred to as "Common Stock Equivalents") without
        payment of any consideration by such holder for the additional shares of
        Common Stock or the Common Stock Equivalents (including the additional
        shares of Common Stock issuable upon conversion or exercise thereof),
        then as of such record date (or the date of such dividend distribution
        split or subdivision if no record date is fixed), the Conversion Price
        of the Series B Preferred Stock shall be appropriately decreased so that
        the number of shares of Common Stock issuable on conversion of each
        share of each such series shall be increased in proportion to such
        increase of outstanding shares.
 
             (ii) If the number of shares of Common Stock outstanding at any
        time after a Purchase Date is decreased by a combination of the
        outstanding shares of Common Stock, then, following the record date of
        such combination, the Conversion Price for the Series B Preferred Stock
        shall be appropriately increased so that the number of shares of Common
        Stock issuable on conversion of each share of each such series shall be
        decreased in proportion to such decrease in outstanding shares.
 
          (d) Other Distributions. In the event this corporation shall declare a
     distribution payable in securities of other persons, evidences of
     indebtedness issued by this corporation or other persons, assets (excluding
     cash dividends) or options or rights not referred to in subsection 4(c)(i),
     then, in each such case for the purpose of this subsection 4(d), the
     holders of Series B Preferred Stock shall be entitled to a proportionate
     share of any such distribution as though they were the holders of the
     number of shares of Common Stock of this corporation into which their
     shares of Series B Preferred Stock are convertible as of the record date
     fixed for the determination of the holders of Common Stock of this
     corporation entitled to receive such distribution.
 
          (e) Recapitalization. If at any time or from time to time there shall
     be a recapitalization of the Common Stock (other than a subdivision,
     combination or merger or sale of assets transaction provided for elsewhere
     in this Section 4 or Section 5), provision shall be made so that the
     holders of Series B Preferred Stock shall thereafter be entitled to receive
     upon conversion of their Series B Preferred Stock, the number of shares of
     stock or other securities or property of this corporation or otherwise, to
     which a holder of Common Stock deliverable upon conversion would have been
     entitled on such recapitalization. In any such case, appropriate adjustment
     shall be made in the application of the provisions of this Section 4 with
     respect to the rights of the holders of Series B Preferred Stock after the
     recapitalization to the end that the provisions of this Section 4
     (including adjustment of the Conversion Price then in effect and the number
     of shares purchasable upon conversion of the Series B Preferred Stock)
     shall be applicable after that event as nearly equivalent as may be
     practicable.
 
          (f) No Impairment. This corporation will not, by amendment of its
     Certificate of Incorporation or through any reorganization,
     recapitalization, transfer of assets, consolidation, merger, dissolution,
     issue or sale of securities or any other voluntary action, avoid or seek to
     avoid the observance or performance of any of the terms to be observed or
     performed hereunder by this corporation, but will at all times in good
     faith assist in the carrying out of all the provisions of this Section 4
     and in the taking of all such action as may be necessary or appropriate in
     order to protect the Conversion Rights of the holders of the Series B
     Preferred Stock against impairment.
 
          (g) Fractional Shares and Certificate as to Adjustments.
 
             (i) No fractional shares shall be issued upon conversion of any
        share or shares of Series B Preferred Stock. All shares of Common Stock
        (including fractions thereof) issuable upon such conversion shall be
        aggregated for purposes of determining whether the conversion would
        result in the issuance of any fractional share. If, after the
        aforementioned aggregation, the conversion would result in the issuance
        of a fraction of a share of Common Stock, the corporation shall, in lieu
        of issuing any fractional share, pay the holder otherwise entitled to
        such fraction a sum in cash equal to
 
                                       E-4
<PAGE>   241
 
        the fair market value of such fraction on the date of conversion (as
        determined in good faith by the Board of Directors).
 
             (ii) Upon the occurrence of each adjustment or readjustment of the
        Conversion Price of Series B Preferred Stock pursuant to this Section 4,
        this corporation, at its expense, shall promptly compute such adjustment
        or readjustment in accordance with the terms hereof and prepare and
        furnish to each holder of Series B Preferred Stock, a certificate
        setting forth such adjustment or readjustment and showing in detail the
        facts upon which such adjustment or readjustment is based. This
        corporation shall, upon the written request at any time of any holder of
        Series B Preferred Stock, furnish or cause to be furnished to such
        holder a like certificate setting forth (A) such adjustment and
        readjustment, (B) the Conversion Price for Series B Preferred Stock at
        the time in effect, and (C) the number of shares of Common Stock and the
        amount, if any, of other property which at the time would be received
        upon the conversion of a share of Series B Preferred Stock.
 
          (h) Notices of Record Date. In the event of any taking by this
     corporation of a record of the holders of any class of securities for the
     purpose of determining the holders thereof who are entitled to receive any
     dividend (other than a cash dividend) or other distribution, any right to
     subscribe for, purchase or otherwise acquire any shares of stock of any
     class or any other securities or property, or to receive any other right,
     this corporation shall mail to each holder of Series B Preferred Stock, at
     least 20 days prior to the date specified therein, a notice specifying the
     date on which any such record is to be taken for the purpose of such
     dividend, distribution or right, and the amount and character of such
     dividend, distribution or right.
 
          (i) Reservation of Stock Issuable Upon Conversion. This corporation
     shall at all times reserve and keep available out of its authorized but
     unissued shares of Common Stock solely for the purpose of effecting the
     conversion of the shares of Series B Preferred Stock such number of its
     shares of Common Stock as shall from time to time be sufficient to effect
     the conversion of all outstanding shares of Series B Preferred Stock; and
     if at any time the number of authorized but unissued shares of Common Stock
     shall not be sufficient to effect the conversion of all then outstanding
     shares of Series B Preferred Stock, in addition to such other remedies as
     shall be available to the holder of Series B Preferred Stock, this
     corporation will take such corporate action as may, in the opinion of its
     counsel, be necessary to increase its authorized but unissued shares of
     Common Stock to such number of shares as shall be sufficient for such
     purposes.
 
          (j) Notices. Any notice required by the provisions of this Section 4
     to be given to the holders of shares of any series of Preferred Stock shall
     be deemed given if deposited in the United States mail, postage prepaid,
     and addressed to each holder of record at his address appearing on the
     books of this corporation.
 
     5. Merger, Consolidation or Reorganization.
 
          (a) A consolidation, merger or other reorganization of this
     corporation with or into another corporation or other entity or person in
     which this corporation shall not be the continuing or surviving entity of
     such merger, consolidation or reorganization, or the sale of all or
     substantially all of this corporation's properties and assets to any other
     person, or any transaction or series of related transactions by this
     corporation in which an excess of 50% of this corporation's voting power is
     transferred shall be deemed to be a liquidation for all purposes of Section
     2 hereof, unless this corporation's stockholders of record immediately
     prior to such merger, consolidation, reorganization, sale or transaction
     are holders of more than 50% of the voting equity securities of the
     surviving corporation.
 
          (b) In the event the requirements of subsection 5(a) are not complied
     with, this corporation shall forthwith either:
 
             (i) cause such closing to be postponed until such time as the
        requirements of this Section 5 have been complied with, or
 
                                       E-5
<PAGE>   242
 
             (ii) cancel such transaction, in which event the rights,
        preferences and privileges of the holders of the Series B Preferred
        Stock shall revert to and be the same as such rights, preferences and
        privileges existing immediately prior to the date of the first notice
        referred to in subsection 5(c) hereof.
 
          (c) This corporation shall give each holder of record of Series B
     Preferred Stock written notice of such impending transaction not later than
     20 days prior to the stockholders' meeting called to approve such
     transaction, or 20 days prior to the closing of such transaction, whichever
     is earlier, and shall also notify such holders in writing of the final
     approval of such transaction. The first of such notices shall describe the
     material terms and conditions of the impending transaction and the
     provisions of this Section 5, and this corporation shall thereafter give
     such holders prompt notice of any material changes. The transaction shall
     in no event take place earlier than 20 days after this corporation has
     given the first notice provided for herein or earlier than ten days after
     this corporation has given notice of any material changes provided for
     herein; provided, however, that such periods may be shortened upon the
     written consent of the holders of a majority of the shares of the Series B
     Preferred Stock then outstanding.
 
     6. Voting Rights. The holders of Series B Preferred Stock shall not be
entitled to vote on any matters except as expressly provided in Section
242(b)(2) of the Delaware General Corporation Law. In such event, the holder of
each share of Series B Preferred Stock shall have the right to one vote for each
share of Common Stock into which such Series B Preferred Stock could then be
converted. In all cases any fractional share, determined on an aggregate
as-converted basis, shall be rounded to the nearest whole share (with one-half
being rounded upward). If the Series B Preferred Stockholders are entitled to
vote, such holders shall be entitled, notwithstanding any provision hereof, to
notice in accordance with the bylaws of this corporation of any stockholders'
meeting that is called to consider a matter as to which the Series B Preferred
Stockholders would be entitled to vote.
 
     7. Status of Converted Stock. In the event any shares of Series B Preferred
Stock shall be converted pursuant to Section 4 hereof, the shares so converted
shall be canceled and shall not be issuable by this corporation.
 
     8. No Preemptive Rights. The holders of the Series B Preferred Stock shall
not have any preemptive rights.
 
     (C) Common Stock. This corporation shall not without first obtaining the
approval (by vote or written consent, as provided by law) of the holders of at
least sixty-six and two-thirds percent (66 2/3%) the then outstanding shares of
Common Stock, voting together as a separate class:
 
          1. sell, convey, or otherwise dispose of or encumber all or
     substantially all of its property or business or merge into or consolidate
     with any other corporation (other than a wholly-owned subsidiary
     corporation) or effect any other transaction or series of related
     transactions in which more than fifty percent (50%) of the voting power of
     the Corporation is disposed of, provided that this provision shall not
     apply to a merger effected exclusively for the purpose of changing the
     domicile of the Corporation;
 
          2. authorize or issue, or obligate itself to issue, any other equity
     security, including any other security convertible into or exercisable for
     any equity security, having a preference over, or being on a parity with,
     the Series B Preferred Stock with respect to voting, dividends, conversion
     or upon liquidation;
 
          3. alter or change the rights, preferences or privileges of the shares
     of Series B Preferred Stock so as to adversely affect them;
 
          4. increase or decrease (other than by conversion) the total number of
     authorized shares of Series B Preferred Stock;
 
          5. redeem, purchase or otherwise acquire (or pay into or set aside for
     a sinking fund for such purpose) any share or shares of Common Stock or
     Preferred Stock, provided however, that this restriction shall not apply to
     the repurchase of shares of Common Stock from employees, officers,
     directors, consultants or other persons performing services for this
     corporation or any subsidiary pursuant to
 
                                       E-6
<PAGE>   243
 
     agreements under which this corporation has the option to repurchase such
     shares at cost or at cost upon the occurrence of certain events, such as
     the termination of employment;
 
          6. declare or pay any dividends on its Common or Preferred Stock; or
 
          7. amend the Corporation's Bylaws.
 
                                   ARTICLE V
 
     Except as otherwise provided in this Amended and Restated Certificate of
Incorporation, in furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to make, repeal, alter,

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the DGCL permits Visioneer's board of directors to indemnify
any person against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with any threatened, pending or completed action, suit or proceeding
in which such person is made a party by reason of his or her being or having
been a director, officer, employee or agent of Visioneer, in terms sufficiently
broad to permit such indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under the Securities Act
of 1933, as amended (the "Act"). The statute provides that indemnification
pursuant to its provisions is not exclusive of other rights of indemnification
to which a person may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors, or otherwise.
 
     Article XI of Visioneer's Certificate of Incorporation provides for
indemnification of its directors, officers, employees and other agents to the
fullest extent permitted by law.
 
     As permitted by sections 102 and 145 of the DGCL, Visioneer's Certificate
of Incorporation eliminates a director's personal liability for monetary damages
to Visioneer and its stockholders arising from a breach or alleged breach of a
director's fiduciary duty except for liability under section 174 of the DGCL or
liability for any breach of the director's duty of loyalty to Visioneer or its
stockholders, for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law or for any transaction from
which the director derived an improper personal benefit.
 
     In addition, Visioneer maintains officers' and directors' insurance
covering certain liabilities that may be incurred by officers and directors in
the performance of their duties.
 
ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES
 
     (a) EXHIBITS
 
     See Exhibit Index for the list of exhibits following the Signature Page of
this Form S-4, which is incorporated herein by reference.
 
     (b) FINANCIAL STATEMENT SCHEDULES

ITEM 22. UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended (the
"Securities Act"), each filing of the registrant's annual report pursuant to
Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as
amended, (the "Exchange Act") (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that
is incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     The undersigned registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
                                      II-1
<PAGE>   246
 
     The registrant undertakes that every prospectus: (i) that is filed pursuant
to the paragraph 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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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 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.
 
     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the undersigned prospectus
pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of
receipt of such request, and to send the incorporated documents by first-class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.
 
     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                Amendment No. 1
                                       to
                        PREFERRED SHARES RIGHTS AGREEMENT
                          dated as of October 23, 1996


        This Amendment No. 1 (this "Amendment") to PREFERRED SHARES RIGHTS
AGREEMENT dated as of October 23, 1996 (the "Rights Agreement") is executed by
Visioneer, Inc. (the "Company") and U.S. Stock Transfer Corporation ("Rights
Agent") and is effective as of the 2nd day of December 1998.

        The parties hereto agree as follows:

        1. Definitions. Unless specifically designated otherwise, capitalized
terms used herein shall have the same meanings given them in the Rights
Agreement.

        2. Amendment. Section 1(a) of the Rights Agreement shall be amended and
restated in its entirety to read as follows:

                "(a) "Acquiring Person" shall mean any Person who or which,
        together with all Affiliates and Associates of such Person, shall be the
        Beneficial Owner of 20% or more of the Common Shares then outstanding,
        but shall not include the Company, any Subsidiary of the Company or any
        employee benefit plan of the Company or of any Subsidiary of the
        Company, or any entity holding Common Shares for or pursuant to the
        terms of any such plan. Notwithstanding the foregoing, no Person shall
        be deemed to be an Acquiring Person either (i) as the result of an
        acquisition of Common Shares by the Company which, by reducing the
        number of shares outstanding, increases the proportionate number of
        shares beneficially owned by such Person to 20% or more of the Common
        Shares of the Company then outstanding; provided, however, that if a
        Person shall become the Beneficial Owner of 20% or more of the Common
        Shares of the Company then outstanding by reason of share purchases by
        the Company and shall, after such share purchases by the Company, become
        the Beneficial Owner of any additional Common Shares of the Company,
        then such Person shall be deemed to be an Acquiring Person, or (ii) if
        within eight days after such Person would otherwise become an Acquiring
        Person (but for the operation of this clause (ii)), such Person notifies
        the Board of Directors that such Person did so inadvertently and within
        two days after such notification, such Person is the Beneficial Owner of
        less than 20% of the outstanding Common Shares. Notwithstanding the
        foregoing, neither ScanSoft, Inc. ("ScanSoft") nor any of its Affiliates
        set forth on Schedule 1 hereto 


                                      -1-
<PAGE>   2



        (collectively, the "Approved Persons") shall be considered an "Acquiring
        Person" in the event such Approved Person shall become the Beneficial
        Owner of Common Stock of the Company pursuant to and not in
        contravention of that certain Agreement and Plan of Merger between
        ScanSoft, Inc. and Visioneer, Inc. dated as of December 2, 1998 (the
        "ScanSoft Merger Agreement").

        Section 1(h) of the Rights Agreement shall be amended and restated in
its entirety to read as follows:

                "(h) "Distribution Date" shall mean the earlier of (i) the Close
        of Business on the tenth day (or such later date as may be determined by
        action of a majority of Continuing Directors then in office) after the
        Shares Acquisition Date (or, if the tenth day after the Shares
        Acquisition Date occurs before the Record Date, the Close of Business on
        the Record Date) or (ii) the Close of Business on the tenth day (or such
        later date as may be determined by action of a majority of Continuing
        Directors then in office) after the date that a tender or exchange offer
        by any Person (other than the Company, any Subsidiary of the Company,
        any employee benefit plan of the Company or of any Subsidiary of the
        Company, or any Person or entity organized, appointed or established by
        the Company for or pursuant to the terms of any such plan) is first
        published or sent or given within the meaning of Rule 14d-2(a) of the
        General Rules and Regulations under the Exchange Act, if, assuming the
        successful consummation thereof, such Person would be the Beneficial
        Owner of 20% or more of the shares of Common Stock then outstanding.
        Notwithstanding the foregoing, no Distribution Date shall occur in the
        event that any Approved Person shall become the Beneficial Owner of
        Common Stock of the Company pursuant to and not in contravention of the
        ScanSoft Merger Agreement.

        Section 1(u) of the Rights Agreement shall be amended and restated in
its entirety to read as follows:

                "(u) "Shares Acquisition Date" shall mean the first date of
        public announcement (which, for purposes of this definition, shall
        include, without limitation, a report filed pursuant to Section 13(d)
        under the Exchange Act) by the Company or an Acquiring Person that an
        Acquiring Person has become such; provided that, if such Person is
        determined not to have become an Acquiring Person pursuant to Section
        l(a)(ii) hereof, then no Shares Acquisition Date shall be deemed to have
        occurred. Notwithstanding the foregoing, no Shares Acquisition Date
        shall 

                                      -2-


<PAGE>   3

        occur in the event that any Approved Person shall become the Beneficial
        Owner of Common Stock of the Company pursuant to and not in
        contravention of the ScanSoft Merger Agreement.

        3. Effect of Amendment. Except as specifically set forth herein, the
terms and conditions contained in the Rights Agreement shall continue in full
force and effect.

        4. Miscellaneous.

               4.1 Governing Law. This Amendment shall be governed by and
construed under the laws of the State of Delaware in the United States of
America as applied to agreements among Delaware residents entered into and to be
performed entirely within such state.

               4.2 Counterparts. This Amendment may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

               4.4 Severability. If one or more provisions of this Amendment are
held to be unenforceable under applicable law, portions of such provisions, or
such provisions in their entirety, to the extent necessary, shall be severed
from this Amendment, and the balance of this Amendment shall be enforceable in
accordance with its terms.

        REGISTRATION STATEMENT ON FORM S-4 (FILE NO. 0-27038)

Ladies and Gentlemen:

        We have examined the Registration Statement on Form S-4 (No. 0-27038)
filed by you with the Securities and Exchange Commission (the "Commission") on
January 14, 1999 (the "Registration Statement"), in connection with the
registration under the Securities Act of 1933, as amended, of 37,516,898 shares
of your Common Stock and 7,179,495 shares of Series B Preferred Stock (the
"Shares"). As your counsel in connection with this transaction, we have examined
the proceedings taken and are familiar with the proceedings proposed to be taken
by you in connection with the issuance of the Shares.

        It is our opinion that upon conclusion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
shares, and upon completion of the proceedings being taken in order to permit
such transactions to be carried out in accordance with the securities laws of
the various states where required, the Shares when issued in the manner
described in the Registration Statement will be legally and validly issued,
fully paid and non-assessable.

        We consent to the use of this opinion as an exhibit to said Registration
Statement, and further consent to the use of our name wherever appearing in said
Registration Statement, including the Prospectus/Joint Proxy Statement
constituting a part thereof, and in any amendment thereto.

                                                   Very truly yours,

October 6, 1997


Mr. J. Larry Smart
21245 Comet Drive
Saratoga, California 95070

Dear Larry:

        The Board of Directors of Visioneer, Inc. (the "Company") is pleased to
offer you a full time employment position starting October 6, 1997 as permanent
President and CEO of Visioneer. You will report directly to the Board and all
Visioneer officers will report to you. Commencing on the date of this agreement,
your base salary will be $293,500 per year, payable in accordance with
Visioneer's standard payroll policy. You will be required to devote all of your
business time and attention to Visioneer's business, except that you may serve
on boards of directors of companies not competitive to Visioneer.

        You will be paid a bonus for the third-quarter of 1997 of $30,000. In
addition, commencing in the fourth quarter of 1997, you will be eligible for
quarterly bonuses based on the fulfillment of certain performance objectives
agreed to between you and the Board on a quarterly basis. The amount of such
quarterly bonuses paid during any twelve month period will not exceed 50% of
your base salary during such twelve month period. In addition, you will receive
up to $5,000 per year for expenses incurred in purchasing private medical (which
will be paid on a quarterly basis) and disability insurance coverage at a cost
greater that the Company's current medical and disability benefits plans.

        If at any time prior to January 6, 1998, your employment relationship
with Visioneer is terminated by the Company other than for Cause (as defined
below), you will continue to be paid your base salary from the date of
termination until January 6, 1998: "Cause" for purposes of this letter shall
mean unsatisfactory performance by you of your duties as determined by the Board
in its sole discretion, breaches of Visioneer policies or agreements,  the
conviction of a felony, committing an act of dishonesty, fraud or intentional
illegal conduct against Visioneer, the misappropriation of Visioneer property,
the breach by you of any other arrangement or relationship between you and
another entity which the Board determines in its sole discretion to be injurious
to Visioneer in a material manner.

        In addition to the above severance payment, which is applicable until
January 6, 1998, if at any time during the period of your employment
relationship with Visioneer, your relationship is terminated by the Company
other than for Cause, you will be entitled to a lump sum severance payment equal
to six months of your base salary existing at the time of such termination.

      The Company granted you on October 6, 1997 an option to purchase 500,000 
shares of Visioneer Common Stock at the price of $3 7/8 per share (the "October 
Option"). The October Option is in addition to the options granted to you in 
April and June of 1997 (the "April Option" and "June Option," respectively). 
The shares granted under the October Option will be incentive stock options 
under the Company's 1993 Incentive Stock Option Plan (the "Plan") to the 
maximum extent permitted by applicable IRS rules, with the balance of such 
options being nonstatutory stock options. These options will vest at the rate 
of 1/48th of the shares subject to the option per month commencing October 6, 
1997 for so long as you remain President and CEO of Visioneer.

      Upon the occurrence of a Change of Control (as defined below), 125,000 of 
the shares subject to the October Option which have not otherwise vested as of 
the effective date of the Change of Control shall immediately vest and may be 
exercised in accordance with the provisions of the October Option and the Plan 
(the "Automatic Accelerated Shares"). "Change of Control" for purposes of this 
letter shall mean a merger or consolidation of the Company in which the voting 
securities of the Company outstanding immediately prior thereto represent 
(either by remaining outstanding or by being converted into voting securities 
of the surviving entity) less than fifty percent (50%) of the total voting 
power represented by the voting securities of the Company or such surviving 
entity outstanding immediately after such merger or consolidation, the complete 
liquidation of the Company, or the sale or disposition by the Company of all or 
substantially all of the Company's assets.

In addition, if your relationship with Visioneer is terminated by the Company 
other than for Cause in connection with a Change of Control, the greater of (i) 
one-half of the unvested shares subject to the October Option that are not 
vested as of the effective date of the Change of Control, after vesting of the 
Automatic Accelerated Shares, or (ii) that number of shares subject to the 
October Option that would have vested if you had remained President and CEO of 
the Company for one year after the date of such termination, shall immediately 
vest and may be exercised in accordance with provisions of the October Option 
and the Plan.

      In addition, the Board has determined that you have achieved the 
performance milestones agreed to between you and the Board based on your 
performance through September 30, 1997, and therefore, in accordance with the 
July 7, 1997 letter agreement between you and Visioneer, the Board has 
accelerated vesting under the June Option (as defined in the July 7, 1997 
letter agreement) with respect to 45,000 shares. You acknowledge that all other 
provisions of the June Option, which provided for the acceleration of vesting 
of an additional 90,000 shares under the June Option under certain conditions 
are hereby terminated, and the June Option and July 7, 1997 letter agreement 
are hereby amended accordingly.

      As with the April Option (also as defined in the July 7, 1997 letter
agreement) and the June Option, the October Option will be subject to the
execution by you of an Option Agreement setting forth in detail these terms.
Under such Option Agreement you will be entitled to exercise the October Option
with respect to the shares that have vested as of the date of termination for 90
days after such date. Except as set forth in this letter agreement, you will not
be entitled to any acceleration of vesting under April Option, June Option or
October Option. You will also
<PAGE>   3


not be entitled to any severance payment in connection with your employment
relationship with the Company or any termination thereof except as set forth in
this agreement. The salary and severance provisions set forth in the April 1,
1997 letter agreement between you and Visioneer shall no longer apply.

        To the extent any severance and other benefits provided for in this
letter agreement constitute "parachute payments" within the meaning of Section
280G of the Internal Revenue Code (the "Code"), you will be entitled to either
(i) such benefits in full, or (ii) such lesser amount which would result in no
portion of such benefits being subject to excise tax under Section 4999 of the
Code, whichever of the foregoing amounts, taking into account the applicable
federal, state and local income taxes and such excise tax result in the receipt
by you on an after-tax basis, of the greatest amount of severance and other
benefits under this agreement.

        Your employment relationship with Visioneer will continue to be "at
will" and will be terminable by either you or Visioneer at any time for any
reason.

        We all look forward to a mutually profitable and enjoyable relationship
as we build Visioneer into a premier data input device company together.

Regards,

Business (the "Hardware Liabilities"), including:

                           (i) all liabilities and obligations relating to the

Total Accounts Payable of the Hardware Business as set forth on the Closing
Balance Sheet (as defined in Section 2.6 below; and

                           (iii) all liabilities and obligations included within

that arise after the Closing Date.

                   (b) OTHER INCLUDED LIABILITIES all liabilities and

Liabilities"). The Hardware Liabilities and Other Liabilities are collectively
referred to herein as the "Assumed Liabilities."

         2.4 EXCLUDED LIABILITIES. All liabilities and obligations of Seller
(whether actual, contingent or otherwise) which are not expressly assumed by
Buyer pursuant to Section 2.3 above shall be excluded from the Assumed
Liabilities, including without limitation the liabilities set forth on Schedule

         2.5 PURCHASE PRICE. Subject to the performance by Seller of all of its
obligations under this Agreement at or prior to the Closing, in consideration of
the acquisition of the Purchased Assets under Section 2.1 and the assumption of
the Assumed Liabilities under Section 2.3, Buyer agrees to deliver to Seller or
to an account or accounts designated by Seller (i) $1,100,000 plus (ii) the net
book value of the Purchased Assets (based on the Closing Balance 



                                      -4-
<PAGE>   5

Sheet (as defined in Section 2.6)) in immediately available funds denominated in
U.S. dollars (collectively, the "Purchase Price").

         2.6 DETERMINATION OF CLOSING BALANCE SHEET. No later than five (5)
business days prior to the Closing Date, Seller shall deliver to Buyer an
unaudited balance sheet of the Hardware Business prepared in accordance with
generally accepted accounting principles ("GAAP") consistently applied, which
shall include Seller's asset and liability accounts as of such date (the "Seller
Balance Sheet"). From the date of the Seller Balance Sheet to the Closing Date,
Buyer and Seller shall mutually monitor and maintain a ledger reflecting
Seller's receipt of payments for accounts receivable, the payment by Seller of
any accounts payable and events that impact any of Seller's other balance sheet
accounts. Based on such events, Buyer and Seller shall agree upon the
appropriate adjustments to be made to the Seller Balance Sheet and any change to
the net book value of the Purchased Assets since the date of the Seller Balance
Sheet. The resulting adjusted balance sheet of Seller, which shall include the
unaudited asset and liability accounts of the Business as of the Closing Date,
shall be known as the "Closing Balance Sheet." Notwithstanding the foregoing,
either party may deliver to the other party prior to the Closing Date written
notice (the "Objection Notice") of its disagreement as to the value of any item
included in the Seller Balance Sheet or in the calculation of any adjustment
thereto pursuant to this Section 2.6. The Objection Notice shall specify in
reasonable detail the nature of such disagreement and the basis and supporting
evidence for the objecting party's position with respect to the disputed
item(s). Seller and Buyer shall attempt in good faith to resolve any
disagreement prior to the Closing Date in order to determine the Closing Balance
Sheet. Buyer and Seller shall each be entitled to review all work papers and
other supporting documentation used in or relevant to the Seller Balance Sheet,
and the calculation of any adjustment thereto pursuant to this Section 2.6. If
Buyer and Seller are unable to reach agreement on the Closing Balance Sheet
prior to the Closing Date, they shall submit the disputed items to Arthur
Andersen L.L.P. (the "Arbitrator"), whose decision with respect to the matters
disputed in the Objection Notice shall be final and binding. Buyer and Seller
shall each promptly provide all information and documents within their
respective possession that the Arbitrator, in its sole discretion, deems
necessary in order to make its decision with respect to the disputed matters.
The fees and expenses of the Arbitrator shall be borne equally by Buyer and
Seller. The Arbitrator shall render its decision with respect to such matters
within 10 days after such matters are submitted to it and then deliver the
Closing Balance Sheet to Buyer and Seller at such time. The Closing shall take
place as soon as practicable thereafter. For purposes of Section 2.5, the net
book value of the Purchased Assets shall not include (i.e. shall be increased
by) liabilities and obligations included within Total Accrued Wages of the
Hardware Business, such as accrued payroll, federal and state income taxes,
commissions, 401(k) contributions made by employees, 401(k) loans payable to
employees, vacation, insurance, Section 125 contributions, and employee stock
purchase plan contributions, except to the extent the parties agree that such
liabilities shall constitute Assumed Liabilities.

         2.7 ALLOCATION OF PURCHASE PRICE. The Purchase Price shall be allocated
among the Purchased Assets as provided in a schedule to be prepared by Buyer
(Schedule 2.7 hereto) for purposes of complying with the requirements of Section
1060 of the Code and the regulations thereunder. As soon as practicable after
the delivery of the Closing Balance Sheet, Buyer shall 



                                      -5-
<PAGE>   6

deliver to Seller a revised allocation reflecting any adjustment to the Seller
Balance Sheet represented by the Closing Balance Sheet, which revised allocation
shall be reasonably consistent with the principles of the allocation set forth
in Schedule 2.7 as determined by Buyer in its good faith discretion. Buyer and
Seller agree to each prepare and file on a timely basis with the Internal
Revenue Service (and applicable state tax authorities) substantially identical
and supplemental Internal Revenue Service Forms 8594 (and corresponding state
tax forms) consistent with Buyer's allocation of the Purchase Price. If any Tax
authority challenges such allocation, the party receiving notice of such
challenge shall give the other prompt written notice thereof and the parties
shall cooperate in order to preserve the effectiveness of such allocation.

         2.8      CERTAIN UNASSIGNED CONTRACTS.

                  (a) Buyer and Seller agree that with respect to all
Distribution and Marketing Agreements listed in Part 4.10 (a)(ii)(B) of the
Disclosure Schedule which constitute a Purchased Asset and Assumed Liability for
which a Consent under such contract is required to assign the rights and
delegate the obligations under such contract to Buyer but not obtained on or
prior to the Closing Date (an "Unassigned Contract"), Seller and Buyer shall
take the following actions: Seller shall (i) promptly transfer to Buyer all
payments to the extent relating to the Hardware Business received from any
third-party under the Unassigned Contract, if applicable; (ii) take, at Buyer's
expense, all reasonable actions to enforce Buyer's rights relating to the
Hardware Business under the Unassigned Contract after prior consultation with
Buyer; and (iii) promptly provide Buyer with a copy of all correspondence,
notices, and other communications received by the third-party under the
Unassigned Contract that relate specifically to Buyer and the Hardware Business.
Buyer shall (i) perform all obligations under the Unassigned Contract which
Buyer would be required to perform thereunder if the Unassigned Contract were

to any third-party that would be required by Buyer; (ii) indemnify and reimburse
Seller for all expenses and costs incurred by Seller arising under or relating
to the Unassigned Contract, and (iii) hold harmless Seller for all expenses and
costs incurred by Buyer arising under or relating to the Unassigned Contract.
Buyer acknowledges that Seller shall not be required to obtain Consents for each
Unassigned Contract, however, Seller shall provide assistance and information
upon Buyer's reasonable request to assist Buyer in negotiating a new contract
with such third parties after the Closing Date.

                  (b) Buyer and Seller agree that with respect to all
Distribution and Marketing Agreements listed in Part 4.10 (a)(ii)(B) of the
Disclosure Schedule which are included as Purchased Assets (either because no
Consent to assignment is required or because such Consent has been obtained)
(each an "Assigned Contract"), Seller and Buyer shall take the following
actions: Buyer shall (i) promptly transfer to Seller all payments to the extent
relating to the Software Business received from any third-party under the
Assigned Contract, if applicable; (ii) take, at Seller's expense, all reasonable
actions to enforce Seller's rights relating to the Software Business under the
Assigned Contract after prior consultation with Seller; and (iii) promptly
provide Seller with a copy of all correspondence, notices, and other
communications received from any third-party under the Assigned Contract that
relates specifically to Seller and the Software Business. Seller shall (i)
perform all applicable 



                                      -6-
<PAGE>   7

obligations under the Assigned Contract which Seller would be required to
perform thereunder if the Assigned Contract had not been assigned to Buyer under
this Agreement, including making any payments directly to any third-party that
would be required by Buyer; (ii) indemnify and reimburse Buyer for all expenses
and costs incurred by Buyer arising under or relating to the Assigned Contract
that were undertaken on behalf of Seller or that relate to Seller's rights in
connection with the Software Business, and (iii) hold harmless Buyer for all
expenses and costs incurred by Seller arising under or relating to the Assigned
Contract. Seller acknowledges that Buyer shall not be required to assist Seller
in negotiating a new contract with such third parties after the Closing Date.

3.       CLOSING.

         3.1 CLOSING. The Closing shall take place at the offices of Venture Law

Affiliate(s) designated by Buyer pursuant to such Transfer Documents.

                  (b) THIRD PARTY CONSENTS AND ASSIGNMENTS. Seller shall deliver

will be required to obtain the consent of its stockholders to such Merger and
change of corporate name at a special meeting of stockholders to be held as soon
as practicable following the execution date of the Merger Agreement and prior to
the effective time of the Merger. Seller acknowledges that the Hardware Assets
include all of Seller's right, title and interest, including intellectual
property rights, in and to the name "Visioneer". Buyer acknowledges Seller's
desire to use the corporate name "Visioneer" after the Closing Date, on the
terms and subject to the below conditions. Effective as of the Closing Date,
Buyer hereby grants to Seller and the successor entity of Seller, if applicable,
a non-exclusive, worldwide, royalty-free, irrevocable, perpetual right and
license, under all of Buyer's intellectual property rights, to use, with right
of sublicense, the name "Visioneer" as the corporate name of Seller (the
"Corporate Name License"). The Corporate Name License shall terminate on the
earlier of (i) one week following the Effective Time of the Merger or (ii) April
30, 1999; provided, however, in the event the Merger does not close by April 30,
1999, Seller shall have the right to use the name "Visioneer" as its legal
corporate name, except that Seller shall do business with a name other than
"Visioneer," and Seller shall recommend to its stockholders at its next annual
meeting of stockholders that Seller change its legal corporate name to a name
not using the name "Visioneer." Seller shall provide to Buyer reasonable
evidence of Seller's change of corporate name in compliance with this Section
3.2(g). In addition, as of the Closing Date, Seller shall inform the California
Secretary of State of Seller's consent to Buyer's use of the name "Visioneer."

         Seller shall use its best efforts to ensure that each affiliate of
Seller listed in Part 4.19 of the Disclosure Schedule enters into a voting
agreement prior to the Closing Date providing that such affiliate agrees to vote
all shares of capital stock of Seller held by it in favor of Seller's
recommendation at its next annual meeting of stockholders to change its
corporate name to a name not using the name "Visioneer."

         Seller acknowledges that Buyer may commence use of the name "Visioneer"
as of the Closing. Buyer and Seller shall cooperate with regard to their
respective uses of the name "Visioneer" between Closing and the termination of
the License to prevent confusion between each of Seller and Buyer and their
respective customers, suppliers and other partners.

                  (h) PRODUCT NAME LICENSE GRANTED TO SELLER. Seller
acknowledges that the Hardware Assets include all of Seller's right, title and
interest, including intellectual property rights, in and to the trademarks of
Seller identified as Purchased Assets in Part 4.9(b) of the Disclosure Schedule.
Buyer acknowledges Seller's desire to use those trademarks on the terms and
subject to the below conditions. Effective as of the Closing Date, Buyer hereby
grants to Seller and the successor of Seller, if applicable, a non-exclusive,
worldwide, royalty-free, irrevocable right and license, under all of Buyer's
intellectual property rights related to Hardware Assets, to use those trademarks
identified as Purchased Assets in Part 4.9(b) of the Disclosure Schedule for the
purposes of marketing, selling and distributing Seller's software products alone
or bundled with third-party products (other than imaging hardware devices (as
that term is defined in the Software License Agreement) with a retail price less
than $300) under the same product name that such products were marketed, sold
and distributed immediately prior to the Closing Date (the "Product Name License
Granted to Seller"). The Product Name License Granted to Seller shall continue
for Seller, any successor of Seller, or any distributor, OEM or reseller
thereof, until March 31, 2000; provided that Seller shall use commercially
reasonable efforts to rename any products to which the Product Name License
Granted to Seller applies as soon as it is feasible to do so.

                  (i) PRODUCT NAME LICENSE GRANTED TO BUYER. Buyer acknowledges
that the Hardware Assets exclude all of Seller's right, title and interest,
including intellectual property rights, in and to the trademarks of Seller set
forth in Part 4.9(b) of the Disclosure Schedule that are identified as not being
Purchased Assets. Seller acknowledges Buyer's desire to use those trademarks on
the terms and subject to the below conditions. Effective as of the Closing Date,
Seller hereby grants to Buyer and its affiliates, if applicable, a
non-exclusive, worldwide, royalty-free, irrevocable right and license, under all
of Seller's intellectual property rights, to use those trademarks set forth in
Part 4.9(b) of the Disclosure Schedule that are identified as not being
Purchased Assets for the purposes of marketing, selling and distributing Buyer's
hardware products alone or bundled with third-party products (except paper
management or OCR software other than software provided by Seller or a successor
Seller) under the same product name that such products were marketed, sold and
distributed immediately prior to the Closing Date (the "Product Name License
Granted to Buyer"). The Product Name License Granted to Buyer shall continue for
Buyer, any successor Buyer, or any distributor, OEM or reseller thereof, until
March 31, 2000; provided that Buyer shall use commercially reasonable efforts to
rename any products to which the Product Name License Granted to Buyer applies
as soon as it is feasible to do so.

         4.6 LEASEHOLD; EQUIPMENT. Seller does not own any real property or any
interest in real property, except for the leaseholds created under the real
property leases identified in Part 4.6 of the Disclosure Schedule (which Part
4.6 indicates that such leaseholds are included as part of the Purchased Assets
hereunder). All such real property is being leased pursuant to lease agreements
that are in full force and effect, are valid and effective in accordance with
their respective terms, and there is not, under any of such leases, any existing
default or event of default (or event which with notice or lapse of time, or

and assets of Seller and identifies which of such assets constitute Purchased
Assets.

         4.8      RECEIVABLES; SIGNIFICANT CUSTOMERS OF THE BUSINESS.

                  (a) Part 4.8(a) of the Disclosure Schedule provides an
accurate and complete breakdown and aging of all accounts receivable of Seller
as of the date of the Seller Unaudited Interim Balance Sheet. All such accounts
receivable are current, and the Company believes that there is reasonable basis
that such accounts receivable will be collected (net of the allowance of
doubtful accounts set forth on the Company Unaudited Interim Balance Sheet,
which allowance the Company believes is reasonable).

                  (b) Part 4.8(b) of the Disclosure Schedule contains an
accurate and complete list as of date of this Agreement of all loans and
advances made by Seller to any employee, director, consultant or independent

Purchased Assets, except the loans and advances indicated on Part 4.8(b) that
were made by Seller to any employee, director, consultant or independent
contractor of Seller offered employment by Merger Party.

                  (c) Part 4.8(c) of the Disclosure Schedule sets forth a
complete and accurate list of all Significant Customers of the Business. For
purposes of this Agreement, "Significant Customers of the Business" are the
thirty (30) customers of the Seller (including without limitation original
equipment manufacturers and royalty-paying customers) that have effected the
most purchases from the Business, in dollar terms, and accounted for the most
revenues for the Business, in dollar terms, during the eight fiscal quarter
period ended September 27, 1998. None of the Company's Significant Customers of
the Business has canceled or returned or, to the knowledge of Seller, is
currently attempting or threatening to cancel or return, any purchases from,
orders to or services provided by the Seller. Seller has not received any
material customer complaints concerning its products and/or services.

         4.9      PROPRIETARY ASSETS.

                  (a) Part 4.9(a) of the Disclosure Schedule sets forth a list
of all patents and patent applications, trademarks (whether or not registered),
trademark applications, trade names, fictitious business names, service marks
(whether or not registered), service mark applications, copyrights (whether or
not registered), copyright applications, maskworks, maskwork applications,
computer software, computer programs (in source and executable form),
proprietary products of Seller and which of such Proprietary Assets are
Purchased Assets. Part 4.9(a) of the Disclosure Schedule indicates each
Proprietary Asset of Seller registered with any Governmental Body or for which
an application has been filed with any Governmental Body and the names of the
jurisdictions covered by the applicable registration or application. Seller owns
no Proprietary Assets registered with any Governmental Body or for which an
application has been filed with any Governmental Body other than the Proprietary
Assets set forth in Part 4.9(a) of the Disclosure Schedule. Part 4.9(a) of the
Disclosure Schedule identifies and provides a brief description of each
Proprietary Asset licensed to Seller by any Person (except for any Proprietary
Asset that is licensed to Seller under any third party software license
generally available to the 



                                      -14-
<PAGE>   15

public at a cost of less than $25,000), and identifies the license agreement
under which such Proprietary Asset is being licensed to Seller. Seller has good
and marketable title to all of the Proprietary Assets identified in Parts 4.9(a)
of the Disclosure Schedule, free and clear of all liens and other Encumbrances,
and has a right to use all of such Proprietary Assets that constitute Purchased
Assets. To Seller's knowledge, except as set forth in Part 4.9(a) of the
Disclosure Schedule, Seller is not obligated to make any payment after the date
of this Agreement to any Person for the use of any Proprietary Asset. To
Seller's knowledge, Seller has not developed jointly with any other Person any
Proprietary Asset with respect to which such other Person has any rights.

                  (b) Seller has taken all reasonable and appropriate steps to
protect and preserve all Seller Proprietary Assets that constitute Purchased
Assets that are not otherwise protected by patents, copyright or maskwork
registrations and that are not publicly known ("Trade Secrets"). The use,
possession or disclosure by Seller of any Proprietary Assets that constitute
Purchased Assets used in the Business but which are not owned by Seller has been
in compliance with the terms and conditions of a valid and enforceable agreement
between Seller and the owner of such Proprietary Assets that constitute
Purchased Assets, or such use, possession or disclosure is otherwise lawful
under the circumstances. To Seller's knowledge, there has been no unauthorized
disclosures of any Trade Secrets, no unauthorized disclosures of any Proprietary
Assets of any third party by Seller or any of its respective employees or
consultants, and there has been no breach of any confidentiality or
nondisclosure agreements to which Seller is a party.

                  (c) Except as set forth in Part 4.9(c) of the Disclosure
Schedule, to Seller's knowledge, none of Seller's Proprietary Assets that
constitute Purchased Assets infringes or conflicts with any Proprietary Asset
owned or used by any other Person and Seller is not infringing, misappropriating
or making any unlawful use of, and Seller has not at any time infringed,
misappropriated or made any unlawful use of, or received any notice or other
communication (in writing or otherwise) of any actual, alleged, possible or
potential infringement, misappropriation or unlawful use of, any Proprietary
Asset owned or used by any other Person. To Seller's knowledge, no other Person
is infringing, misappropriating or making any unlawful use of, and no
Proprietary Asset owned or used by any other Person infringes or conflicts with,
any Proprietary Asset of Seller that constitutes a Purchased Asset.

                  (d) There has not been any claim by any customer or other
Person alleging that any Proprietary Asset of Seller that constitutes a
Purchased Asset (including each version thereof that has ever been licensed or
otherwise made available by Seller to any Person) does not conform in all
material respects with any specification, documentation, performance standard,
representation or statement made or provided by or on behalf of Seller. Seller
has established adequate reserves on the Seller Unaudited Interim Balance Sheet
to cover all costs that Seller reasonably anticipates to be associated with any
obligations that Seller may have with respect to the correction or repair of
programming errors or other defects in the Proprietary Assets.

                  (e) Seller's Proprietary Assets constitute all the Proprietary
Assets necessary to enable Seller to conduct the Hardware Business in the manner
in which such Hardware 



                                      -15-
<PAGE>   16

Business has been and is being conducted. Except as set forth in Part 4.9(e) of
the Disclosure Schedule (which Part 4.9(e) indicates whether or not such
disclosure relates to the Purchased Assets), (i) Seller has not licensed any of
the Proprietary Assets to any Person on an exclusive basis, and (ii) Seller has
not entered into any material restriction on the right or ability of Seller (A)
to compete in any market or geographic area with any other Person, (B) to
acquire any product or other asset or any services from any other Person, to
sell any product or other asset to or perform any services for any other Person
or to transact business or deal in any other manner with any other Person, or
(C) to develop or distribute any technology.

                  (f) All current and former employees have executed and
delivered to Seller an agreement (containing no exceptions to or exclusions from
the scope of its coverage) that is substantially identical to the form of
confidential information and invention assignment agreement previously delivered
to Buyer and identified as satisfying the conditions of this Section 4.9(f). All
current and former consultants and independent contractors to Seller have
executed and delivered to Seller an agreement (containing no exceptions to or
exclusions from the scope of its coverage) that is substantially identical to
the form of consultant confidential information and invention assignment
agreement previously delivered to Buyer and identified as satisfying the
conditions of this Section 4.9(f).

         4.10     CONTRACTS.

                  (a) Part 4.10 of the Disclosure Schedule identifies each
Contract of Seller that constitutes a "Material Contract" and indicates whether
or not each such Contract is a Purchased Asset. For purposes of this Agreement,
each of the following shall be deemed to constitute a "Material Contract":

Schedule, such reference also states whether or not such payment is an Assumed
Liability for purposes of this Agreement) and (C) any Contract or Plan
(including, without limitation, any stock option plan, stock appreciation plan

any Proprietary Asset is licensed to Seller under any third party software
license generally available to the public); or (B) with respect to the
distribution or marketing of any products of Seller, in each case the absence of
which would have a Material Adverse Effect on Seller or the Hardware Business;

                  (e) No Person is renegotiating, or has a right pursuant to the
terms of any Material Contract to renegotiate, any amount paid or payable to
Seller under any Material Contract or any other material term or provision of

except for: (a) Liabilities identified as such in the "liabilities" column of
the Seller Unaudited Interim Balance Sheet; (b) normal and recurring liabilities

in which such business is currently being conducted. All Governmental
Authorizations held by Seller are valid and in full force and effect. Seller is,

requirements of such Governmental Authorizations. Seller has not received any
notice or other communication from any Governmental Body regarding (a) any
actual or possible violation of or failure to comply with any term or
requirement of any Governmental Authorization, or (b) any actual or possible

any Governmental Authorization.

         4.15     TAX MATTERS.

                  (a) All Tax Returns required to be filed by or on behalf of

financial statements.

                  (b) Seller's Financial Statements fully accrue all actual and

Closing Date or accrued in the Company's financial statements.

                  (c) Except as provided in Seller's Disclosure Schedules, no

other Person) that is still in effect, and no such extension or waiver is
currently being requested from Seller.

                  (d) No claim or Legal Proceeding is pending or, to the best of
the knowledge of Seller, has been threatened against or with respect to Seller
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 Seller 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 Seller and with
respect to which adequate reserves for payment have been established). There are
no liens for material Taxes upon any of the assets of any of Seller except liens

                  (e) Seller is not, nor has it ever been, a party to or bound
by any tax indemnity agreement, tax sharing agreement, tax allocation agreement
or similar Contract, other than agreements to which only the Seller is a party.

         4.16     EMPLOYEE AND LABOR MATTERS; BENEFIT PLANS.

                  (a) Part 4.16(a) of the Disclosure Schedule identifies each
salary, bonus, deferred compensation, incentive compensation, stock purchase,
stock option, severance pay, termination pay, hospitalization, medical, life or
other insurance, supplemental unemployment benefits, profit-sharing, pension or
retirement plan, program or agreement (collectively, the "Plans") sponsored,
maintained, contributed to or required to be contributed to by Seller for the
benefit of any current or former employee of Seller.

                  (b) Seller does not maintain, sponsor or contribute to, and
Seller has not 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"), whether or not
excluded from coverage under specific Titles or Merger Subtitles of ERISA) for
the benefit of its employees or former employees (a "Pension Plan"). None of the
Plans identified in Part 4.16(a) of the Disclosure Schedule is subject to Title
IV of ERISA or Section 412 of the Code.

                  (c) Seller does not maintain, sponsor or contribute to any:
(i) employee welfare benefit plan (as defined in Section 3(1) of ERISA, whether
or not excluded from coverage under specific Titles or Merger Subtitles of

Plan"), or (ii) self-funded medical, dental or other similar Plan. None of the
Plans identified in Part 4.16(a) of the Disclosure Schedule is a multi-employer
plan (within the meaning of Section 3(37) of ERISA).

                  (d) With respect to each Plan, Seller has made available to
Buyer: (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

each Summary of Material Modifications, if required under ERISA, with respect to




                                      -20-
<PAGE>   21

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; (v) accurate and complete copies
of all Contracts relating to such Plan, including service provider agreements,
insurance Contracts, minimum premium Contracts, stop-loss agreements, investment
management agreements, subscription and participation agreements and
recordkeeping agreements; and (vi) 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).

                  (e) Seller is not nor has it 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. Seller has never been a member of
an "affiliated service group" within the meaning of Section 414(m) of the Code.
Seller has never made a complete or partial withdrawal from a multi-employer
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).

                  (f) Seller does not have any plan or commitment to create any
Welfare Plan or any additional Pension Plan, or to modify or change any existing
Pension Plan (other than to comply with applicable law) in a manner that would
affect any of its employees.

                  (g) No Plan provides death, medical or health benefits
(whether or not insured) with respect to any current or former employee of
Seller after any such employee's termination of service (other than (i) benefit
coverage mandated by applicable law, including coverage provided pursuant to
Section 4980B of the Code, (ii) deferred compensation benefits accrued as
liabilities on the Seller Balance Sheet, and (iii) benefits the full cost of
which are borne by current or former employees of Seller (or the employees'
beneficiaries)).

                  (h) With respect to any Plan constituting a group health plan
within the meaning of Section 4980B(g)(2) of the Code, to the knowledge of the
Seller, the provisions of Section 4980B of the Code ("COBRA") have been complied
with in all material respects. Part 2.16(h) of the Disclosure Schedule describes
all obligations of Seller as of the date of this Agreement under any of the
provisions of COBRA.

                  (i) Each of the Plans has been operated and administered in
all material respects in accordance with applicable Legal Requirements,
including but not limited to ERISA and the Code.

                  (j) To the knowledge of the Seller, each of the Plans intended
to be qualified under Section 401(a) of the Code has received a favorable
determination from the Internal Revenue Service or has remaining a period of
time in which to file an application for such determination, and the Company is
not aware of any reason why any such determination letter should be revoked or
not issued.

                  (k) Neither the execution, delivery or performance of this
Agreement or the Merger Agreement, nor the consummation of the Merger thereunder
or the transaction contemplated by this Agreement, or any of the other
transactions contemplated by this Agreement or the Merger Agreement, will result
in any payment (including any bonus, golden parachute or severance payment) to
any current or former employee, consultant, or director of Seller (whether or
not under any Plan), or materially increase the benefits payable under any Plan,
or result in any acceleration of the time of payment or vesting of any such
benefits. If any such payment is disclosed in Part 4.16(k) of the Disclosure
Schedule, such reference also states whether or not such payment is an Assumed
Liability for purposes of this Agreement.

                  (l) Part 4.16(l) of the Disclosure Schedule contains a list of
all employees of Seller as of the date of this Agreement, and correctly
reflects, in all material respects, their base salaries, their targeted annual
bonus amounts, their dates of employment and their positions. Seller is not a
party to any collective bargaining Contract or other Contract with a labor union
involving any of its employees. All of Seller's employees are "at will"
employees under applicable law.

                  (m) Part 4.16(m) of the Disclosure Schedule identifies each
employee who is not fully available to perform work because of disability or
other leave and sets forth the basis of such leave and the anticipated date of
return to full service.

respects with all applicable Legal Requirements. To Seller's knowledge, Seller
is in compliance in all material respects with all Contracts relating to
employment, employment practices, wages, bonuses and terms and conditions of
employment, including employee compensation matters.

                  (o) Seller has good labor relations, and it has no knowledge
of any facts indicating that (i) the consummation of the Merger pursuant to the
Merger Agreement or the transaction contemplated by this Agreement or any of the
other transactions contemplated by this Agreement or the Merger Agreement will
have a Material Adverse Effect on the labor relations of Seller, or (ii) any of
the Hardware Employees (as defined in Section 7.1 below) intends to terminate
his or her employment with Seller prior to the Closing

         4.17 ENVIRONMENTAL MATTERS. Seller is in compliance in all material
respects with all applicable Environmental Laws, which compliance includes the
possession by Seller of all permits and other Governmental Authorizations
required under applicable Environmental Laws, and compliance with the terms and
conditions thereof. Seller has not received any notice or other communication
(in writing or otherwise), whether from a Governmental Body, citizens group,
employee or otherwise, that alleges that it is not in compliance with any
Environmental Law, and, to the best of the knowledge of Seller, there are no
circumstances that may prevent or interfere with the compliance by Seller with
any Environmental Law in the future. To the best of the knowledge of Seller, no
current or prior owner of any property leased or controlled by Seller has
received any notice or other communication (in writing or otherwise), whether
from a Government Body, citizens group, employee or otherwise, that alleges that
such current or prior owner or Seller is not in compliance with any
Environmental Law. To the best knowledge of 



                                      -22-
<PAGE>   23

Seller, all property that is leased to, controlled by or used by Seller, and all
surface water, groundwater and soil associated with or adjacent to such property
is in clean and healthful condition and is free of any material environmental
contamination of any nature.

         4.18 INSURANCE. Seller has delivered to Buyer a copy of each insurance
policy and each self insurance program relating to the business, assets or
operations of Seller. Each such insurance policy is in full force and effect.
Seller has not received any notice or other communication regarding any actual
or possible (a) cancellation or invalidation of any insurance policy, (b)
refusal of any coverage or rejection of any material claim under any insurance
policy, or (c) material adjustment in the amount of the premiums payable with
respect to any insurance policy. There is no pending claim (including any
workers' compensation claim) under or based upon any insurance policy of Seller;
and, to the best of the knowledge of Seller, no event has occurred, and no
condition or circumstance exists, that might (with or without notice or lapse of
time) directly or indirectly give rise to or serve as a basis for any such
claim.

         4.19 TRANSACTIONS WITH AFFILIATES. Except as set forth in the Seller
SEC Documents, since the date of the Seller's last proxy statement filed with
the SEC, no event has occurred that would be required to be reported by Seller
pursuant to Item 404 of Regulation S-K promulgated by the SEC. Part 4.19 of the
Disclosure Schedule identifies each Person who is an "affiliate" (as that term
is used in Rule 145 promulgated under the Securities Act) of Seller as of the
date of this Agreement.

         4.20 LEGAL PROCEEDINGS; ORDERS.

                  (a) There are no pending Legal Proceedings (including, to the
best knowledge of Seller, any investigation), and no Person has overtly
threatened to commence any Legal Proceeding, except as set forth in Part 4.20(a)
of the Disclosure Schedule (which Part 4.20(a) indicates whether or not such
Legal Proceedings are Purchased Assets or Purchased Liabilities): (i) that
involves Seller or any of the assets owned or used by Seller, including, without
limitation, any Proprietary Asset of Seller; or (ii) that challenges, or that
may have the effect of preventing, delaying, making illegal or otherwise
interfering with any of the transactions contemplated by this Agreement or the
Merger Agreement. To the best knowledge of Seller, no event has occurred, and no
claim, dispute or other condition or circumstance exists, that will, or that
could reasonably be expected to, give rise to or serve as a basis for the
commencement of any such Legal Proceeding. To the best knowledge of Seller, no
event has occurred, and no claim, dispute or other condition or circumstance
exists, that will, or that could reasonably be expected to, cause or provide a
basis for a director, officer or other Representative of Seller to seek
indemnification from, or commence a Legal Proceeding against or involving
Seller.

                  (b) There is no order, writ, injunction, judgment or decree to
which Seller, or any of the assets owned or used by Seller, is subject. To the
best knowledge of Seller, no officer or other employee of Seller is subject to
any order, writ, injunction, judgment or decree that prohibits such officer or
other employee from engaging in or continuing any conduct, activity or practice
relating to the business of Seller.

and by equitable principles.

         5.4 CONSENT AND APPROVALS. There is no requirement applicable to Buyer

6.       COVENANTS.

         6.1 ACCESS TO INFORMATION. Prior and subsequent to the Closing, Seller
will permit Buyer to make a full and complete investigation of the Purchased
Assets and Assumed Liabilities and to receive from Seller all information of
Seller relating to the Purchased Assets and Assumed Liabilities or reasonably
related to Seller's conduct of the hardware Business. Without limiting this
right, Seller will give to Buyer and its accountants, legal counsel, and other
representatives full access, during normal business hours, at a mutually
agreeable location arranged in advance, to all of the books, records, files,
documents, properties, and Contracts of Seller relating to the Purchased Assets
and Assumed Liabilities or reasonably related to Seller's conduct of the
Hardware Business and allow Buyer and any such representatives to make copies
thereof, all of which shall be made available in an organized fashion and so as
to facilitate an orderly review. This Section 6.1 shall not affect or be deemed
to modify any representation or warranty contained herein or the conditions to
the obligations of the parties to consummate the transactions contemplated by
this Agreement. Seller shall maintain and make available the information and
records specified in this Section 6.1(a) in the ordinary course of Seller's
business and document retention policies, as if the transactions contemplated by
this Agreement had not occurred.

         6.2 THIRD PARTY CONSENTS. Seller and Buyer shall use commercially
reasonable efforts to obtain, within the applicable time periods required, all
Consents, waivers, permits, consents and approvals and to effect all
registrations, filings and notices with or to third parties or Governmental
Entities which are necessary to consummate the transactions contemplated by this
Agreement so as to preserve all rights of and benefits to, and all obligations
of, the Buyer in the Purchased Assets and under the Assumed Liabilities,
respectively.

         6.3 CERTAIN NOTIFICATIONS. At all times prior to the Closing, Seller
and Buyer shall promptly notify the other party in writing of the occurrence of
any event which will result, or has a reasonable prospect of resulting, in the
failure to satisfy any of the conditions specified in Section 8 or Section 9 of
this Agreement.

         6.4 BEST EFFORTS. Except where otherwise expressly stated, Seller and
the Buyer shall use their best efforts to cause to be fulfilled and satisfied

respectively and to cause to be performed all of the matters required by them at
the Closing.

         6.5 SELLER'S CONDUCT OF THE BUSINESS PRIOR TO CLOSING. During the
period from the date of this Agreement to the Closing Date, Seller will conduct
the Business in its ordinary and usual course, consistent with past practice,
and will use all commercially reasonable efforts to preserve intact all rights,
privileges, franchises and other authority of the Business, to retain employees,
and to maintain favorable relationships with licensors, licensees, suppliers,
Contractors, distributors, customers, and others having relationships with the
Business. Seller shall promptly notify Buyer of any event or occurrence or
emergency not in the ordinary course of business, and any material event
involving the Hardware Business, the Purchased Assets or the Assumed
Liabilities. Without limiting the generality of the foregoing, and except as
approved in writing by Buyer in advance, prior to the Closing or as provided in
this Agreement, Seller:

                  (a) will not create, incur or assume (i) any borrowings under
capital leases, or (ii) any obligation which would in any material way affect
the Hardware Business, the Purchased Assets, the Assumed Liabilities or Buyer's
ability to conduct the Hardware Business in substantially the same manner and
condition as conducted by Seller on the date of this Agreement;

                  (b) will not change in any manner the compensation of, or
agree to provide additional benefits to, or enter into any employment agreement
with, any Hardware Employee;

                  (c) will maintain insurance coverage in amounts adequate to
cover the reasonably anticipated risks of the business conducted with the
Purchased Assets;

                  (d) will not acquire or agree to acquire by merging or
consolidating with, or by purchasing any assets or equity securities of, or by
any other manner, any business or any corporation, partnership, association or
other business organization or division thereof, or otherwise acquire or agree
to acquire any assets which are material, individually or in the aggregate, to
the Hardware Business;

                  (e) will not sell, dispose of or encumber any of the Purchased
Assets or license any Purchased Assets to any Person except for the sale of
Inventory in the normal course of business;

                  (f) will not enter into any agreements or commitments relating
to the Hardware Business, except on commercially reasonable terms in the
ordinary course of business of the Hardware Business;

                  (g) will comply in all material respects with all laws and
regulations applicable to the Business;

                  (h) will use reasonable efforts to assist Buyer in employing
the Hardware Employees;

                  (i) will not change or announce any change to the products or

                                      -28-
<PAGE>   29

                  (j) will not violate, amend or otherwise change in any
material way the terms of any of the Material Contracts that constitute
Purchased Assets;

                  (k) will not commence a lawsuit related to or involving the
Hardware Business, the Purchased Assets or the Assumed Liabilities other than
(a) for the routine collection of bills; (b) for injunctive relief on the
grounds that Seller has suffered immediate and irreparable harm not compensable
in money damages, provided that Seller has obtained the prior written consent of
Buyer, such consent not to be unreasonably withheld; or (c) for a breach of this
Agreement, the Merger Agreement or any of the transactions contemplated thereby;
or

                  (l) will not assign, sell or otherwise convey to any third
party, any of the accounts receivable relating to the Hardware Business prior to
the Closing Date.

         6.6 NO OTHER BIDS. Until the earlier to occur of (a) the Closing or (b)
the termination of this Agreement pursuant to its terms, Seller shall not, and
Seller shall not authorize any of its Representatives to, directly or
indirectly, (i) initiate, solicit or encourage (including by way of furnishing
information regarding the Hardware Business or the Purchased Assets) any
inquiries, or make any statements to third parties which may reasonably be
expected to lead to any proposal concerning the sale of the Hardware Business or
the Purchased Assets (other than to Merger Party and its Representatives in
connection with the Merger), or (ii) negotiate, engage in any substantive
discussions, or enters into any agreement, with any Person concerning the sale
of Seller, the Business or the Purchased Assets (other than with the Merger
Party and its Representatives). Notwithstanding the foregoing, if Seller or any
of its Representatives shall receive an unsolicited set of terms, expression of
interest, inquiry, proposal or offer from any Person, entity or group (other
than Buyer and its Representations) relating to possible acquisition of the
Business or the Hardware Business ( an "Alternative Proposal"), then, (i) Seller
will give Buyer Parent prompt written notice thereof, providing the identity of
the other Person, entity or group, and a detailed description of the material
terms of such Alternative Proposal, and (ii) to the extent the Board of
Directors of Seller believes in good faith that such Alternative Proposal
represents a Superior Offer, and the Board of Directors of Seller determines in
good faith after consultation with outside legal counsel that it is necessary
for the Board of Directors of Seller to comply with its fiduciary duties to
Seller's stockholders under applicable law, Seller and its Representatives may
furnish in connection therewith information and take such other actions
consistent with the fiduciary obligations of the Board of Directors of Seller,
and such actions shall not be considered a breach of any obligations of Seller
hereunder. Notwithstanding the foregoing, if Buyer delivers to Seller a detailed
written proposal within five (5) business days of Buyer's receipt of the
material terms of the Alternative Proposal, and for which the economic value to
Seller is substantively the same or better than the economic value of a Superior
Offer as determined in good faith by Seller's outside legal counsel and
financial advisors ("Buyer's Proposal"), Seller shall accept Buyer's Proposal
and shall not accept the Superior Offer, and Buyer and Seller shall in good
faith and within five (5) business days of Seller's acceptance of Buyer's
Proposal amend this Agreement or enter into any additional agreements to reflect
the terms of Buyer's Proposal. In the event Seller does not receive Buyer's
Proposal within such period of time, or if Seller does so receive Buyer's
Proposal and Buyer and Seller are unable to amend this Agreement or enter into
any additional agreements within such period of time, Seller 



                                      -29-
<PAGE>   30

shall have no further obligation to negotiate with Buyer under this Section 6.6,
and shall have the right to take such actions consistent with the fiduciary
obligations of the Board of Directors of Seller.

         6.7 TAX RETURNS. Seller shall, to the extent that failure to do so
could adversely affect the Business or the Purchased Assets following Closing,
provide reasonable assistance to Buyer upon its request to enable Buyer to file
in a timely manner all returns and reports relating to Taxes, and such returns
and reports shall be true, correct and complete and shall be subject to the
review and consent of Buyer which consent shall not be unreasonably withheld.

         6.8 NO POST-CLOSING RETENTION OF COPIES. Immediately after the Closing,
Seller shall deliver to Buyer or destroy copies of Purchased Assets in Seller's
possession that are in addition to copies delivered to Buyer as part of the
Closing, whether such copies are in paper form, on computer media or stored in
another form; provided, however, that Seller may retain and use copies of all
books, records, files and papers, whether in hard copy or electronic format,
used in the Hardware Business listed in Section 2.1(a)(xiii) above as well as
other documents required by law to be kept by Seller for the sole purpose of
preparing its statutory accounts; and provided further, that Seller may retain
copies of and use in a manner that is reasonably related to the conduct of its
business (other than for distribution, marketing or sale of an imaging hardware
device (as defined in the Software License Agreement) with a retail price of
$300 or less) the customer lists included in Section 2.1(a)(xiii) as Purchased
Assets.

         6.9 CONFIDENTIALITY; PUBLIC ANNOUNCEMENTS. Buyer and Seller acknowledge
that they previously executed a Mutual Nondisclosure Agreement, dated as of
September 29, 1998, and agree that such agreement will continue in full force
and effect in accordance with its terms. Buyer and Seller will have agreed to
the text of a joint press release announcing the signing of this Agreement and,
if required by Seller, the Merger Agreement. Buyer and Seller shall consult with
each other before issuing any other press release or otherwise making any public
statement with respect to this Agreement, the Merger, or any of the other
transactions contemplated by this Agreement or the Merger Agreement. Without
limiting the generality of the foregoing, neither party shall or shall permit
any of its Representatives to make any disclosure regarding this Agreement, the
Merger or any of the other transactions contemplated by this Agreement or the
Merger Agreement unless (a) the other party shall have approved such disclosure
or (b) the other party shall have been advised in writing by its outside legal
counsel that such disclosure is required by applicable law; provided that such
party notifies the other party prior to making such disclosure.

         6.10 POST-CLOSING ACTIONS. Subsequent to the Closing Date, Seller
shall, from time to time, execute and deliver, upon the request of Buyer, all
such other and further materials and documents and instruments of conveyance,
transfer or assignment as may reasonably be requested by Buyer to effect, record
or verify the transfer to, and vesting in Buyer, of Seller's right, title and
interest in and to the Purchased Assets, free and clear of all Liens, in
accordance with the terms of this Agreement.

attributable to the transactions contemplated by this Agreement. Buyer shall
provide Seller with a resale certificate within thirty (30) days following the

paid with regard to the transfer of the Purchased Assets to Buyer.

         6.13 FIRPTA COMPLIANCE. On or prior to the Closing Date, Buyer shall
deliver to Seller a properly executed statement in a form reasonably acceptable

bulk sales laws with respect to the transfer of the Purchased Assets and Assumed
Liabilities to Buyer.

shall negotiate in good faith to enter into a services agreement pursuant to
which Buyer shall provide to Seller certain administrative services to be agreed
upon between Buyer and Seller at Buyer's actual cost to enable Seller to
continue to operate its Software Business after the Closing Date and for a
period of six (6) months following the effective time of the Merger in a manner
substantially similar to the manner in which it was operated prior to the
Closing Date, which services shall include, among other things, office and
conference space at Seller's current facilities, provided Buyer maintains a
lease at such address; use of the telephone system, computer systems and other
infrastructure at Seller's current facilities; payroll services; accounting
services; and customer and technical support services (the "Services

Seller shall obtain an executed consent to assignment from its landlord in
connection with Seller's assignment to Buyer of that certain Lease Agreement

employees and consultants of Seller listed on Exhibit D (the "Hardware

The terms and conditions of such Offer to each Hardware Employee shall be in
writing, and, except as otherwise specifically agreed to by such Hardware
Employee, Buyer shall hire all Hardware Employees to whom it has made such an

Closing Date;

                           (ii) Buyer agrees not to terminate any Hired Employee
other than for Cause during the six month period following the Closing Date
unless it provides such terminated employee a severance benefit equal to the
remaining amount of salary such Hired Employee would have been paid if such

period. "Cause" means fraud, theft, the commission of any crime or similar act
or a material violation of any employment practice or policy of Buyer, any of
which result in material injury to Buyer;

                           (iii) Hired Employees shall be assigned to positions

initial employment by Buyer, be required to take a drug test or a physical
examination; and

                           (v) Hired Employees shall be eligible to participate
in the employee benefit plans offered to comparably situated employees of Buyer
beginning on the date of commencement of employment with Buyer in accordance

                  C. In connection with and at the time of the execution of the
Purchase Agreement, Mr. Smart, the current President and Chief Executive Officer
of Seller, has entered into that certain Employment and Non-Compete Agreement by
and between Mr. Smart and Buyer (the "Employment Agreement"), pursuant to which,
among other things, Buyer has agreed to employ Mr. Smart, and Mr. Smart has
agreed to accept employment with Buyer, in the capacity as the Chief Executive
Officer of Buyer, with such employment to commence upon the Employment
Commencement Date (as defined below). Until that time, Mr. Smart will retain his
current position with Seller, but will also render services to Buyer pursuant to
the terms of this Agreement.

                                    * * * * *

                  In consideration of the foregoing and the mutual covenants
contained herein, the parties hereto agree as follows:

         1. MANAGEMENT SERVICES. During the term of this agreement, Seller will
cause Mr. Smart to provide, and Mr. Smart hereby agrees that he will provide,
management services (the "Services") to Buyer as described on Exhibit A attached
to this Agreement. Seller shall use best efforts to cause Mr. Smart to perform
the Services in a manner satisfactory to Buyer.

         2. FEES; SUPPORT. As consideration for the Services to be provided
hereunder and other obligations, Buyer will compensate Seller for the services
of Mr. Smart in accordance with 


<PAGE>   2

the terms set forth in Exhibit B to this Agreement. In addition, Buyer will
provide Mr. Smart with such support facilities and space as may be required in
Buyer's judgment to enable him to properly perform the Services.

         3. EXPENSES. Buyer agrees to reimburse any and all expenses incurred by
Seller or Mr. Smart pursuant to the terms set forth in Exhibit B. As a condition
to receipt of reimbursement, Seller or Mr. Smart shall be required to submit to
Buyer reasonable evidence that the amount involved was expended and related to
the Services provided under this Agreement.

         4. TERM AND TERMINATION. The obligation to provide the Services
described hereunder shall commence at 12:01 a.m. on the day following the
Closing Date (as that term is defined in the Purchase Agreement) and shall
continue until the Employment Commencement Date, as defined herein (the
"Management Services Period").

         5. INDEPENDENT CONTRACTOR. The relationship of Seller and of Mr. Smart
to Buyer will be that of an independent contractor and not that of an employee.
Neither Seller nor Mr. Smart will be eligible for any employee benefits during
the Management Services Period, nor will Buyer make deductions from payments
made to Seller for taxes, all of which will be Seller's responsibility. Seller
agrees to indemnify and hold Buyer harmless from any liability for, or
assessment of, any such taxes imposed on Buyer by relevant taxing authorities.

         6. SUPERVISION OF MANAGEMENT SERVICES. All Management Services to be
performed hereunder will be as agreed between Seller or Mr. Smart on the one
hand and Raymond Liang of Buyer. Mr. Smart will be required to report to Mr.
Liang concerning the Management Services performed under this Agreement. The
nature and frequency of these reports will be left to the mutual agreement of
Mr. Liang and Mr. Smart.

         7. EMPLOYMENT COMMENCEMENT DATE. The Employment Commencement Date as
that term is used in this Agreement shall mean 12:01 a.m. on the day following
the earliest of (a) the Merger Closing Date, (b) any day prior to the Merger
Closing Date on which the Agreement and Plan of Merger referred to above is
terminated by either party in accordance with its terms, or (c) March 31, 1999.
On the Employment Commencement Date, Mr. Smart shall become a full-time employee
in accordance with the terms of the Employment Agreement, the employment of Mr.
Smart by Seller shall cease, and Mr. Smart shall resign any and all positions as
an officer of Seller or any successor to Seller.

         8.       MISCELLANEOUS.

                  (a) AMENDMENTS AND WAIVERS. Any term of this Agreement may be
amended or waived only with the written consent of the parties.

                  (b) SOLE AGREEMENT. This Agreement, including the Exhibits
hereto, constitutes the sole agreement of the parties and supersedes all oral
negotiations and prior writings with respect to the subject matter hereof.

                  (c) NOTICES. Any notice required or permitted by this
Agreement shall be in writing and shall be deemed sufficient upon receipt, when
delivered personally or by courier, overnight delivery service or confirmed
facsimile, or forty-eight (48) hours after being deposited in the regular mail
as certified or registered mail (airmail if sent internationally) with postage
prepaid, if such notice is addressed to the party to be notified at such party's
address or facsimile number as set forth below, or as subsequently modified by
written notice.

                  (d) CHOICE OF LAW. The validity, interpretation, construction
and performance of this Agreement shall be governed by the laws of the State of
California, without giving effect to the principles of conflict of laws.

                  (e) SEVERABILITY. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot
reach a mutually agreeable and enforceable replacement for such provision, then
(i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded and
(iii) the balance of the Agreement shall be enforceable in accordance with its
terms.

                  (f) COUNTERPARTS. This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
together will constitute one and the same instrument.

                  (g) ARBITRATION. Any dispute or claim arising out of or in
connection with any provision of this Agreement will be finally settled by
binding arbitration in San Jose, California in accordance with the rules of the
American Arbitration Association by one arbitrator appointed in accordance with
said rules. The arbitrator shall apply California law, without reference to
rules of conflicts of law or rules of statutory arbitration, to the resolution
of any dispute. Judgment on the award rendered by the arbitrator may be entered
in any court having jurisdiction thereof. Notwithstanding the foregoing, the
parties may apply to any court of competent jurisdiction for preliminary or
interim equitable relief, or to compel arbitration in accordance with this
paragraph, without breach of this arbitration provision. This Section 9(g) shall
not apply to the Confidentiality Agreement.

                  (h) ADVICE OF COUNSEL. EACH PARTY ACKNOWLEDGES THAT, IN
EXECUTING THIS AGREEMENT, SUCH PARTY HAS HAD THE OPPORTUNITY TO SEEK THE ADVICE
OF INDEPENDENT LEGAL COUNSEL, AND HAS READ AND UNDERSTOOD ALL OF THE TERMS AND
PROVISIONS OF THIS AGREEMENT. THIS AGREEMENT SHALL NOT BE CONSTRUED AGAINST ANY
PARTY BY REASON OF THE DRAFTING OR PREPARATION HEREOF.

                     SETTLEMENT AGREEMENT AND MUTUAL RELEASE

      This Settlement Agreement and Mutual Release ("Agreement") is entered
into by and between Visioneer, Inc. ("Visioneer"), Primax V Acquisition
Corp., a California company ("Purchaser"), Primax Electronics, Ltd., a
company organized under the laws of Taiwan ("Purchaser Parent") and Michael
T. Burt ("Employee").

      WHEREAS, Employee has been employed by Visioneer;

      WHEREAS, Visioneer, Purchaser and Purchaser Parent have entered into that
certain Asset Purchase Agreement dated December 2, 1998 (the "Purchase
Agreement") pursuant to which Visioneer has agreed to sell and transfer to
Purchaser and Purchaser has agreed to purchase and assume from Visioneer
substantially all of the assets and liabilities associated with Visioneer's
Hardware Business (as defined in the Purchase Agreement);

      WHEREAS, Visioneer and Employee have mutually agreed to terminate the
current employment relationship between Employee and Visioneer;

      WHEREAS, Purchaser, Purchaser Parent and Employee have mutually agreed not
to enter into any future employment relationship between Employee and either of
Purchaser or Purchaser Parent; and

      WHEREAS, Employee on the one hand, and Visioneer, Purchaser and Purchaser
Parent on the other hand, wish to release each other from any claims arising
from or related to any current or anticipated employment relationship;

      NOW, THEREFORE, in consideration of the mutual promises made herein,
Visioneer, Purchaser, Purchaser Parent and Employee (collectively referred to as
the "Parties") hereby agree as follows:

      1. Termination. The Parties acknowledge and agree that Employee's
employment relationship with Visioneer will terminate effective as of the
Closing Date (as defined in Section 3.1 of the Purchase Agreement) (the
"Termination Date").

      2. Consideration. In consideration for the release of claims set forth
below and other obligations under this Agreement, Visioneer, Purchaser and
Purchaser Parent collectively agree to pay Employee a lump sum amount of
$70,000.02, which is equal to six months of Employee's regular base salary (less
applicable tax withholding).

      3. Stock Options.

            (a) Acceleration of Vesting. Employee acknowledges and agrees that
in accordance with the terms of those certain stock options granted to Employee
under Visioneer's 1993 Incentive Stock Option Plan to purchase a total of
130,715 shares of Visioneer Common 

<PAGE>   2
Stock, as evidenced by Stock Option Agreements issued to Employee, 42,901 shares
will have vested as of the Termination Date and 87,814 shares will remain
unvested (the "Unvested Shares"). In further consideration for the release of
claims set forth below and other obligations under this Agreement, the Parties
agree that fifty percent (50%) of Employee's Unvested Shares shall become
immediately vested and exercisable as of the Termination Date. No additional
option shares shall vest after the Termination Date. In accordance with the
terms of the Option Agreements issued to Employee, vested options will be
exercisable for ninety (90) days following the Termination Date.

            (b) Option Buy-Back. The requirement that Employee continue to be
employed by Visioneer as of January 31, 1999 in order to qualify to sell any or
all of his vested, unexercised stock options back to Visioneer at a purchase
price of $0.20 per share is hereby waived, and Employee shall hereafter be
eligible to participate in the proposed Option Buy-Back (pursuant to its
specified terms) at his sole election.

      4. Benefits. Employee shall continue to receive Visioneer's standard
medical and dental insurance benefits at Visioneer's expense through the
Termination Date. After such date, Employee shall have the right to continue, at
his own expense, coverage under Visioneer's health insurance as provided by the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA").

      5. No Other Payments Due. Employee acknowledges and agrees that he has
received, or will receive as of the Termination Date, all salary, accrued
vacation, commissions, bonuses, compensation, shares of stock options therefore
or other such sums due to Employee other than the amounts to be paid pursuant to
Sections 2 and 3 of this Agreement. In light of all such payments by or on
behalf of Visioneer, Purchaser and/or Purchaser Parent of all wages due, or to
become due to the Employee, the Parties further acknowledge and agree that
California Labor Code Section 206.5 is not applicable to the Parties hereto.
That section provides in pertinent part as follows:

                  No employer shall require the execution of any release of any
                  claim or right on account of wages due, or to become due, or
                  made as an advance on wages to be earned, unless payment of
                  such wages has been made.

      6. Release of Claims. Employee agrees that the foregoing consideration
represents settlement in full of all outstanding obligations owed to Employee by
any of Visioneer, Purchaser and/or Purchaser Parent. Employee further agrees
that with respect to (i) any payment(s) made to Employee hereunder or (ii)
benefit(s) conferred upon Employee hereunder by either Visioneer, Purchaser or
Purchaser Parent, that the other two parties hereto (i.e., either (i) Visioneer
and Purchaser, or (ii) Purchaser and Purchaser Parent, or (iii) Visioneer and
Purchaser Parent) shall be deemed to be third-party beneficiaries of such
actions. Employee, on the one hand, and Visioneer, Purchaser and Purchaser
Parent, on the other hand, on behalf of themselves, and each of their respective
heirs, executors, officers, directors, employees, investors, shareholders,
administrators, predecessor and successor corporations and assigns, 

<PAGE>   3
hereby fully and forever release each other and their respective heirs,
executors, officers, directors, employees, investors, shareholders,
administrators, predecessor and successor corporations and assigns from any
claim duty, obligation or cause of action relating to any matters of any kind,
whether known or unknown, suspected or unsuspected, that either of them may
possess arising from any omissions, acts or facts that have occurred up until
and including the Effective Date of this Agreement including, without
limitation:

            (a) any and all claims relating to or arising from Employee's
employment relationship with Visioneer and termination of that relationship as
of the Termination Date, and any anticipated future employment relationship
between Employee and either of Purchaser or Purchaser Parent;

            (b) any and all claims relating to, or arising from, Employee's
right to purchase, or actual purchase of shares of stock of Visioneer (other
than as specifically set forth in Section 3 herein above);

            (c) any and all claims for wrongful discharge of employment; breach
of contract, both express and implied; breach of a covenant of good faith and
fair dealing, both express and implied; negligent or intentional infliction of
emotional distress; negligent or intentional misrepresentation; negligent or
intentional interference with contract or prospective economic advantage; and
defamation;

            (d) any and all claims for violation of any federal, state or
municipal statute, including, but not limited to, Title VII of the Civil Rights
Act of 1964, the Age Discrimination in Employment Act of 1967, and the
California Fair Employment and Housing Act;

            (e) any and all claims arising out of any other laws and regulations
relating to employment or employment discrimination; and

            (f) any and all claims for attorney's fees and costs.

The Parties agree that the release set forth in this section shall be and remain
in effect in all respects as a complete and general release as to the matters
released. This release does not extend to any obligations incurred under this
Agreement.

      7. Civil Code Section 1542. The Parties represent that they are not aware
of any claim by either of them other than the claims that are released by this
Agreement. Employee, on the one hand, and Visioneer, Purchaser and Purchaser
Parent, on the other hand, acknowledge that they are familiar with the
provisions of California Civil Code Section 1542, which provides as follows:

            A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
            NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING
            THE RELEASE,
<PAGE>   4
            WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT
            WITH THE DEBTOR.

      The Parties being aware of such code section, agree respectively to waive
any rights they may have thereunder, as well as under any other stature or
common law principles of similar effect.

      8. Acknowledgment of Waiver of Claims under ADEA. Employee acknowledges
that he is waiving and releasing any rights he may have under the Age
Discrimination in Employment Act of 1967 ("ADEA") and that the waiver and
release is knowing and voluntary. The Parties agree that the waiver and release
does not apply to any rights or claims that may arise under ADEA after the
Effective Date (as defined below) of this Agreement. Employee acknowledges that
the consideration given for this waiver and release Agreement is in addition to
anything of value to which Employee was already entitled. Employee further
acknowledges that he has been advised by the writing that (a) he should consult
with an attorney prior to executing this Agreement; (b) he has at least
twenty-one (21) days within which to consider this Agreement; (c) he has at
least seven (7) days following the execution of this Agreement by the Parties to
revoke this Agreement (the "Revocation Period"); and (d) this Agreement shall
not be effective until the Revocation Period has expired.

      9. Confidentiality. The Parties hereto each agree to use their best
efforts to maintain in confidence the existence of this Agreement, the contents
and terms of this Agreement, and the consideration for this Agreement
(hereinafter collectively referred to as "Settlement Information"). Each Party
hereto agrees to take every reasonable precaution to prevent disclosure of any
Settlement Information to third parties, and each agrees that there will be no
publicity, directly or indirectly, concerning any Settlement Information. The
Parties hereto agree to take every precaution to disclose Settlement Information
only to those employees, officers, directors, attorneys, accountants,
governmental entities, and family members who have a reasonable need to know of
such Settlement Information.

      10. Nondisclosure of Confidential and Proprietary Information. Employee
understands and agrees that his obligations to Visioneer under the Confidential
Information and Assignment of Inventions Agreement previously executed by
Employee and Visioneer shall survive termination of Employee's relationship with
Visioneer under this Agreement and that Employee shall continue to maintain the
confidentiality of all confidential and propriety information of Visioneer,
Purchaser and Purchaser Parent to which he has had access. Employee agrees that
at all times hereafter, Employee shall not intentionally divulge, furnish or
make available to any party any of the trade secrets, patents, patent
applications, price decisions or determinations, inventions, customers,
proprietary information or other intellectual property rights of Visioneer,
Purchaser or Purchaser Parent, until after such time as such information has
become publicly known otherwise than by an act of collusion of Employee.
Employee further agrees that he will return all property and confidential and
proprietary information of Visioneer, Purchaser and Purchaser Parent in his
possession to such Party within five business days after the Termination Date.

<PAGE>   5

      11. Breach of this Agreement. Employee acknowledges that upon breach of
the confidential and proprietary information provision contained in Section 10
of this Agreement, Visioneer, Purchaser and/or Purchaser Parent would sustain
irreparable harm from such breach, and, therefore, Employee agrees that in
addition to any other remedies which Visioneer, Purchaser and/or Purchaser
Parent may have for any breach of this Agreement or otherwise, including
termination of such Parties' respective obligations to provide benefits to
Employee as described in Sections 2, 3 and 4 of this Agreement, Visioneer,
Purchaser and Purchaser Parent shall be entitled to obtain equitable relief,
including specific performance and injunctions, restraining Employee from
committing or continuing any such violation of this Agreement.

      12. Non-Disparagement. Each Party agrees to refrain from any
disparagement, criticism, defamation, slander of the others, or tortious
interference with the contracts and relationships of the others.

      13.. No Admission of Liability. The Parties understand and acknowledge
that this Agreement constitutes a compromise and settlement of disputed claims.
No action taken by the Parties hereto, or either of them, either previously or
in connection with this Agreement shall be deemed or construed to be (a) an
admission of the truth or falsity of any claims heretofore made or (b) an
acknowledgment or admission by either party of any fault or liability whatsoever
to the other party or to any third party.

      14. Authority. Each of Visioneer, Purchaser and Purchaser Parent
represents and warrants that the undersigned have the authority to act on behalf
of Visioneer, Purchaser and Purchaser Parent, respectively, and to bind
Visioneer, Purchaser and Purchaser Parent, respectively, and all who may claim
through any of them to the terms and conditions of this Agreement. Employee
represents and warrants that he has the capacity to act on his own behalf and on
behalf of all who might claim through him to bind them to the terms and
conditions of this Agreement. Each Party warrants and represents that there are
no liens or claims of lien or assignments in law or equity or otherwise of or
against any of the claims or causes of action released herein.

      15. No Representations. Each Party represents that it has carefully read
and understands the scope and effect of the provisions of this Agreement. No
Party has relied upon any representations or statements made by the other
Parties which are not specifically set forth in this Agreement.

      16. Costs. The Parties shall each bear their own costs, attorneys' fees
and other fees incurred in connection with this Agreement.

      17. Severability. In the event that any provision hereof becomes or is
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement shall continue in full force and effect without said
provision.

      18. Entire Agreement. This Agreement represents the entire agreement and
understanding between the Parties concerning Employee's separation from
Visioneer and 

<PAGE>   6
supersedes and replaces any and all prior agreements and understandings
concerning Employee's relationship with any of Visioneer, Purchaser and/or
Purchaser Parent and his compensation by any of them other than any option
agreement as described in Section 3 and other than the Confidential Information
and Assignment of Inventions Agreement as described in Section 10.

      19. No Oral Modification. This Agreement may only be amended in writing
signed by each of the Parties.

      20. Governing Law. This Agreement shall be governed by the laws of the
State of California.

      21. Effective Date. This Agreement shall be effective upon the expiration
of the Revocation Period described in Section 8 and such date is referred to
herein as the "Effective Date".

      22. Counterparts. This Agreement may be executed in counterparts, and each
counterpart shall have the same force and effect as an original and shall

     This Election is subject to the terms and conditions set forth in the
Merger Agreement and the Proxy Statement/Prospectus, dated January 19, 1999 (the
"Proxy Statement/Prospectus"), furnished to stockholders of Visioneer in
connection with the Merger, all of which are incorporated herein by reference.
Receipt of the Proxy Statement/Prospectus, including the Merger Agreement
attached as Annex A thereto, is hereby acknowledged. Copies of the Proxy
Statement/Prospectus are available upon request from Visioneer (see Instruction
H(10)).
 
     It is understood that because pursuant to the Merger Agreement the number
of shares of Visioneer Common Stock to be exchanged for shares of Surviving
Corporation common stock in the Merger and the number of shares of Visioneer
Common Stock to be converted into the right to receive $2.06 per share in cash
in the Merger are subject to limitations, no assurance can be given that an
Election by any given stockholder, including this Election by the undersigned,
can be accommodated. Rather, the Election by each holder of Visioneer Common
Stock, including this Election by the undersigned, will be subject to the
results of the election and allocation procedures set forth in the Merger
Agreement and described in the Proxy Statement/ Prospectus under the caption
"The Merger-Merger Consideration" (the "Election and Allocation Procedures").

ACCOMPANIED BY STOCK CERTIFICATES (OR A PROPER GUARANTY OF DELIVERY, AS
DESCRIBED BELOW), NO LATER THAN 5:00 P.M., EASTERN TIME, ON FEBRUARY 23, 1999,
IN ORDER TO ASSURE THAT THEIR FORM OF ELECTION WILL BE RECEIVED BY THE ELECTION

pursuant to the following procedures: (1) Box E ("Guarantee of Delivery") must

     IF THE EXCHANGE AGENT HAS NOT RECEIVED YOUR PROPERLY COMPLETED FORM OF
ELECTION, ACCOMPANIED BY YOUR STOCK CERTIFICATES, BY THE ELECTION DEADLINE
(UNLESS BOX E (GUARANTY OF DELIVERY) HAS BEEN PROPERLY COMPLETED AND SUCH
CERTIFICATES ARE RECEIVED BY THE EXCHANGE AGENT BY THE GUARANTEED DELIVERY
DEADLINE), YOU WILL BE DEEMED TO HAVE MADE A NON-ELECTION.
 
     For instructions regarding changes of Election and the time in which such
changes can be made, see Instruction G(1) below.
 
B. ELECTIONS
 
     This Form of Election provides for your Election, subject to the Election
and Allocation Procedures and the other items and conditions set forth hereunder
and in the documents incorporated herein by reference, upon consummation of the
Merger to have the shares of Visioneer Common Stock covered by this Form of
Election (the "Visioneer Shares") converted into the right:
 
     - to receive $2.06 in cash for each Visioneer Share (a "Cash Election"); or
 
     - to receive Surviving Corporation Common Stock for each of the Visioneer
       Shares (a "Stock Election"); or
 
     - to receive $2.06 in cash for a desired percentage of the Visioneer Shares
       and Surviving Corporation Common Stock for each of the remaining
       Visioneer Shares (a "Mixed Election").
 
     A HOLDER OF SHARES OF VISIONEER COMMON STOCK THAT DOES NOT SUBMIT AN
EFFECTIVE FORM OF ELECTION PRIOR TO THE ELECTION DEADLINE WILL BE DEEMED TO HAVE
MADE A STOCK ELECTION.

     You should understand that your Election is subject to certain terms and
conditions that are set forth in the Merger Agreement and described in the Proxy
Statement/Prospectus. The Merger Agreement is included as Annex A to the Proxy
Statement/Prospectus. Copies of the Proxy Statement/Prospectus may be requested
from Visioneer (see Instruction H(10)). The delivery of this Form of Election to
the Exchange Agent constitutes acknowledgment of the receipt of the Proxy
Statement/Prospectus. EACH HOLDER OF VISIONEER COMMON STOCK IS STRONGLY
ENCOURAGED TO READ THE PROXY STATEMENT/PROSPECTUS IN ITS ENTIRETY AND TO DISCUSS
THE CONTENTS THEREOF, THE MERGER AND THIS FORM OF ELECTION WITH HIS OR HER
PERSONAL FINANCIAL AND TAX ADVISORS PRIOR TO DECIDING WHAT ELECTION TO MAKE. THE
TAX CONSEQUENCES TO A HOLDER OF VISIONEER COMMON STOCK WILL VARY DEPENDING UPON
A NUMBER OF FACTORS, INCLUDING WHETHER SUCH HOLDER RECEIVES SURVIVING
CORPORATION COMMON STOCK, CASH OR A COMBINATION THEREOF. FOR CERTAIN INFORMATION
REGARDING THE FEDERAL INCOME TAX CONSEQUENCES OF AN ELECTION, SEE "THE
MERGER -- FEDERAL INCOME TAX CONSEQUENCES" IN THE PROXY STATEMENT/ PROSPECTUS.
 
C. CASH ELECTION
 
     If you elect, subject to the Election and Allocation Procedures and the
other terms and conditions set forth in this Form of Election, including the
documents incorporated herein by reference, to receive cash for all of the
shares of Visioneer Common Stock covered by this Form of Election, you should
check the "Cash Election" box on the first page of this Form of Election.
 
D. STOCK ELECTION
 
     If you elect, subject to the Election and Allocation Procedures and the
other terms and conditions set forth in this Form of Election, including the
documents incorporated herein by reference, to receive Surviving Corporation
common stock for all of the shares of Visioneer Common Stock covered by this
Form of Election, you should check the "Stock Election" box on the first page of
this Form of Election.
 
E. MIXED ELECTION
 
     If you elect, subject to the Election and Allocation Procedures and other
terms and conditions set forth in this Form of Election, including the documents
incorporated herein by reference, to receive cash for some of the shares of
Visioneer Common Stock covered by this Form of Election and to receive Surviving
Corporation common stock for the remainder of the shares of Visioneer Common
Stock covered by this Form of Election, you should check the "Mixed Election"
box and complete the box immediately below such box on the first page of this
Form of Election.
 
     No fractional Surviving Corporation common stock will be issued in
connection with the Merger. A holder of Visioneer Common Stock who makes a Stock
Election or Mixed Election, or who would otherwise receive a fractional share of
Surviving Corporation common stock in connection with the Merger, will instead
receive a cash payment equal to such fraction multiplied by $2.06.
 
     If you have failed to make an effective Cash Election, Stock Election or
Mixed Election for all of the shares of Visioneer Common Stock required to be
covered by this Form of Election, or if your Election is deemed by the Exchange
Agent to be defective in any way, or if your Form of Election is not accompanied
by your certificates (unless Box E (Guaranty of Delivery) has been properly
completed and such certificates are received by the Exchange Agent by the
Guaranteed Delivery Deadline), you will be deemed to have made a Stock Election
for all of such shares.
 
G. SPECIAL CONDITIONS
 
     (1) Change of Election. An effective Election may be changed by the person
or persons making such Election by a written notice signed and dated by such
person or persons received by the Exchange Agent no later than 5:00 Eastern Time
on the Election Deadline.
                                       10
<PAGE>   11
 
     (2) Nullification of Election. All Forms of Election will be void and of no
effect if the Merger is not consummated, and certificates submitted therewith
shall be promptly returned to the persons submitting the same.
 
     (3) Elections Subject to Allocation. All Elections are subject to the
Election and Allocation Procedures set forth in the Merger Agreement and
described in the Proxy Statement/Prospectus under the caption "The Merger-Merger
Consideration" and to the other terms and conditions set forth thereunder and
hereunder, including the documents incorporated herein by reference.
 
     (4) Shares Held by Nominees, Trustees or other Representatives. Holders of
record of shares of Visioneer Common Stock who hold such shares as nominees,
trustees or in other representative or fiduciary capacities (a "Representative")
may submit one or more Forms of Election covering the aggregate number of shares
of Visioneer Common Stock held by such Representative for the beneficial owners
for whom the Representative is making an Election; provided, that such
Representative certifies that each such Form of Election covers all the shares
of Visioneer Common Stock held by such Representative for a particular
beneficial owner. Any Representative who makes an Election may be required to
provide the Exchange Agent with such documents and/or additional certifications,
if requested, in order to satisfy the Exchange Agent that such Representative
holds such shares of Visioneer Common Stock for a particular beneficial owner of
such shares. If any shares held by a Representative are not covered by an
effective Form of Election, they will be deemed to be covered by a Share
Election.
 
H. GENERAL
 
     (1) Execution and Delivery. In order to make an effective Election, you
must correctly fill out this Form of Election, or a facsimile thereof. After
dating and signing it, you are responsible for its delivery, accompanied by all
stock certificates representing Visioneer Common Stock currently held by you or
a proper Guaranty of Delivery of such stock certificates pursuant to Instruction
A, to the Exchange Agent at the address set forth on the front of this Form of
Election by the Election Deadline. YOU MAY CHOOSE ANY METHOD TO DELIVER THIS
FORM OF ELECTION; HOWEVER, YOU ASSUME ALL RISK OF NON-DELIVERY. IF YOU CHOOSE TO
USE THE MAIL, WE RECOMMEND THAT YOU USE REGISTERED MAIL, RETURN RECEIPT
REQUESTED, AND THAT YOU PROPERLY INSURE ALL STOCK CERTIFICATES.
 
     DELIVERY OF STOCK CERTIFICATES WILL BE DEEMED EFFECTIVE AND RISK OF LOSS
WITH RESPECT TO SUCH CERTIFICATES SHALL PASS ONLY WHEN SUCH CERTIFICATES ARE
ACTUALLY RECEIVED BY THE EXCHANGE AGENT.
 
     (2) Signatures. Except as otherwise permitted below, you must sign this
Form of Election exactly the way your name appears on the face of your
certificates. If the shares are owned by two or more persons, each must sign
exactly as his or her name appears on the face of the certificates. If shares of
Visioneer Common Stock have been assigned by the registered owner, this Form of
Election should be signed in exactly the same way as the name of the assignee
appearing on the certificates or transfer documents. See Instructions H(5)(a)
and H(5)(b).
 
     (3) Notice of Defects; Resolution of Disputes. Neither Visioneer nor the
Exchange Agent will be under any obligation to notify you or anyone else that
the Exchange Agent has not received a properly completed Form of Election or
that any Form of Election submitted is defective in any way.
 
     Any and all disputes with respect to Forms of Election or to Elections made
in respect of Visioneer Common Stock (including but not limited to matters
relating to the Election Deadline, time limits, defects or irregularities in the
surrender of any stock certificate, effectiveness of any Election and
computations of allocations) will be resolved by Visioneer and its decision will
be conclusive and binding on all concerned. Visioneer may delegate this function
to the Exchange Agent in whole or in part. Visioneer or the Exchange Agent shall
have the absolute right in its sole discretion to reject any and all Forms of
Election and surrenders of stock certificates which are deemed by either of them
to be not in proper form or to waive any immaterial irregularities in any Form
of Election or in the surrender of any stock certificate. Surrenders of stock
 
                                       11
<PAGE>   12
 
certificates will not be deemed to have been made until all defects or
irregularities that have not been waived have been cured.
 
     (4) Issuance of Payment Check(s) and New Certificate in Same Name. If the
certificate representing shares of Surviving Corporation Common Stock and/or the
Payment Check(s) are to be issued in the name of the registered holder(s) as
inscribed on the surrendered certificate(s), the surrendered certificate(s) need
not be endorsed and no guarantee of the signature on the Form of Election is
required. For corrections in name and change in name not involving changes in
ownership, see Instruction H(5)(c).
 
     (5) Issuance of Payment Check(s) and New Certificate in Different Name. If
the certificate representing shares of Surviving Corporation Common Stock and/or
the Payment Check(s) are to be issued in the name of someone other than the
registered holder(s) of the surrendered certificate(s), you must follow the
guidelines below. Note that in each circumstance listed below, stockholder(s)
must have signature(s) guaranteed in Box C and complete Box F.
 
          (a) Endorsement and Guarantee. The certificate(s) surrendered must be
     properly endorsed (or accompanied by appropriate stock powers properly
     executed) by the registered holder(s) of such certificate(s) to the person
     who is to receive the Surviving Corporation Common Stock and/or the Payment
     Check(s). The signature(s) of the registered holder(s) on the endorsement
     or stock powers must correspond with the name(s) written upon the face of
     the certificate(s) in every particular, with the signatures on the
     Certificate(s) (or stock powers) guaranteed by an eligible institution. An
     eligible institution is a bank, broker dealer, credit union, savings
     association or other entity which is a member in good standing of the
     Securities Transfer Agent's Medallion Program.
 
          (b) Transferee's Signature. The Form of Election must be signed by the
     transferee or assignee or his or her agent, and should not be signed by the
     transferor or assignor. See Box B entitled "Sign Here." The signature of
     such transferee or assignee must be guaranteed by an eligible institution
     as provided in Instruction H(5)(a).
 
          (c) Correction of or Change in Name. For a correction of name or for a
     change in name which does not involve a change in ownership, proceed as
     follows: For a change in name by marriage, etc., the Form of Election
     should be signed, e.g., "Mary Doe, now by marriage Mary Jones." For a
     correction in name, the Form of Election should be signed, e.g., "James E.
     Brown, incorrectly inscribed as J.E. Brown." The signature in each case
     should be guaranteed in the manner described in Instruction H(5)(a) above
     and Box F should be completed.
 
     You should consult your own tax advisor as to any possible tax consequences
resulting from the issuance of shares of Surviving Corporation common stock
certificate and/or Payment Check(s) in a name different from that of the
registered holder(s) of the surrendered certificate(s).
 
                                       12
<PAGE>   13
 
     (6) Supporting Evidence. In case any Form of Election, certificate
endorsement or stock power is executed by an agent, attorney, administrator,
executor, guardian, trustee or any person in any other fiduciary or
representative capacity, or by an officer of a corporation on behalf of the
corporation, there must be submitted (with the Form of Election, surrendered
certificate(s), and/or stock powers) documentary evidence of appointment and
authority to act in such capacity (including court orders and corporate
resolutions when necessary), as well as evidence of the authority of the person
making such execution to assign, sell or transfer the certificate(s). Such
documentary evidence of authority must be in form satisfactory to the Exchange
Agent.
 
     (7) Special Instructions for Delivery by the Exchange Agent. The
certificate representing Surviving Corporation common stock and/or the Payment
Check(s) will be mailed to the address of the registered holder(s) as indicated
under Box A entitled "Certificate Information," unless instructions to the
contrary are given in Box G entitled "Special Mailing Instructions."
 
     (8) Lost Certificates. If you are not able to locate your certificates
representing Visioneer Common Stock, you should contact U.S. Stock Transfer
Corporation, Visioneer's transfer agent, at: 1745 Gardena Avenue, Suite 200,
Glendale, California 91204, (818) 502-1404. In such event, U.S. Stock Transfer
will forward additional documentation which the shareholder must complete in
order to effectively surrender such lost or destroyed certificate(s). There may
be a fee to replace lost certificates.
 
     (9) Federal Income Tax Withholding. Under Federal income tax law, the
Exchange Agent is required to file a report with the Internal Revenue Service
disclosing any payments of cash being made to each holder of certificates
formerly representing shares of Visioneer Common Stock pursuant to the Merger
Agreement. In order to avoid "backup withholding" of Federal income tax on any
cash received upon the surrender of certificate(s), a holder thereof must,
unless an exemption applies, provide the Exchange Agent with his or her correct
taxpayer identification number ("TIN") on Substitute Form W-9, which is part of
this Form of Election (Box D), and certify, under penalties of perjury, that
such number is correct and that such holder is not otherwise subject to backup
withholding. If the correct TIN and certifications are not provided, a $50
penalty may be imposed by the Internal Revenue Service and payments made for
surrender of certificate(s) may be subject to backup withholding of 31%. In
addition, if a holder makes a false statement that results in no imposition of
backup withholding, and there was no reasonable basis for making such a
statement, a $500 penalty may also be imposed by the Internal Revenue Service.
 
     Backup withholding is not an additional Federal income tax. Rather, the
Federal income tax liability of a person subject to backup withholding will be
reduced by the amount of such tax withheld. If backup withholding results in an
overpayment of income taxes, a refund may be obtained from the Internal Revenue
Service.
 
     The TIN that must be provided on the Substitute Form W-9 is that of the
registered holder(s) of the certificate(s) at the Effective Time. The TIN for an
individual is his or her social security number. The box in Part II of the
Substitute Form W-9 may be checked if the person surrendering the certificates
has not been issued a TIN and has applied for a TIN or intends to apply for a
TIN in the near future. If the box in Part II has been checked, the person
surrendering the certificate(s) must also complete the Certificate of Awaiting
Taxpayer Identification Number in order to avoid backup withholding.
Notwithstanding that the box in Part II is checked (and the Certificate of
Awaiting Taxpayer Identification Number is completed), the Exchange Agent will
withhold 31% on all cash payments with respect to surrendered certificate(s)
made prior to the time it is provided with a properly certified TIN.
 
     Exempt persons (including, among others, corporations) are not subject to
backup withholding. A foreign individual may qualify as an exempt person by
submitting Form W-8 or a substitute Form W-8, signed under penalties of perjury,
certifying to such person's exempt status. A form of such statement can be
obtained from the Exchange Agent. A certificate holder should consult his or her
tax advisor as to such holder's qualification for an exemption from backup
withholding and the procedure for obtaining such exemption.

I. DELIVERY OF SHARE OF SURVIVING CORPORATION COMMON STOCK AND PAYMENT CHECKS
 
     As soon as practicable after the Merger becomes effective, the Exchange
Agent will make the allocations of cash and Surviving Corporation common stock
to be received by holders of Visioneer Common Stock or their designees in
accordance with the Election and Allocation Procedures. The Exchange Agent will
thereafter issue and mail to you a check for any cash and/or any certificate or

delivered the required certificates for your Visioneer Common Stock in

forward to you, as soon as practicable after the Merger becomes effective, a
Letter of Transmittal for you to use to send in your certificates for shares of
Visioneer Common Stock, containing appropriate instructions for surrendering
such certificates at that time. After the Exchange Agent receives your stock
certificates with a properly completed Letter of Transmittal, it will issue and
mail to you a check for any cash and/or any certificate or certificates for
shares of Surviving Corporation common stock to which you are entitled (and, if
applicable, a check in lieu of a fractional share), provided you have delivered
the required certificates for your Visioneer Common Stock in accordance with the
terms and conditions of the Letter of Transmittal, including the documents
incorporated therein by reference.
