               We are proposing a merger of InfoSpace and Go2Net

Q: What is the proposed merger? (see page 44)

A. In the proposed merger, a wholly-owned subsidiary of InfoSpace will merge
   with and into Go2Net. Go2Net will survive the merger as a wholly-owned
   subsidiary of InfoSpace. The merger agreement is attached to this joint
   proxy statement/prospectus as Annex A. You are encouraged to read it
   carefully.

Q: What will the Go2Net stockholders receive in the merger? (see page 70)

A. Following the merger:

   . Go2Net common stockholders will receive, in exchange for each of their
     Go2Net shares, 1.82 shares of InfoSpace common stock.

   . Each option to purchase Go2Net common stock outstanding immediately
     before the completion of the merger will automatically become an option
     to purchase shares of InfoSpace common stock. The number of shares of
     InfoSpace common stock which may be purchased under such option will be
     equal to the product of the number of Go2Net shares that were purchasable
     before the merger multiplied by 1.82. The exercise price per share will
     be the pre-merger exercise price divided by 1.82.

   . Instead of fractional shares in the merger, Go2Net stockholders will
     receive cash in an amount equal to such fraction multiplied by the
     average closing prices reported on the Nasdaq National Market for
     InfoSpace common stock for the five (5) trading days immediately
     preceding the effective date of the merger.

Q: When do you expect the merger to be completed?

A. InfoSpace and Go2Net are working toward completing the merger as quickly as
   possible. We hope to complete the merger no later than December 31, 2000.

Q: Are there risks involved in undertaking the merger?

A. Yes. In evaluating the merger, you should carefully consider the factors
   discussed in the section of the joint proxy statement/prospectus entitled
   "Risk Factors" beginning on page 10.

Q: What are the conditions to completion of the merger? (see page 76)

A. InfoSpace's and Go2Net's respective obligations to complete the merger are
   subject to the satisfaction or waiver of specified closing conditions. If
   either InfoSpace or Go2Net waives any conditions, each company will consider
   the facts and circumstances at that time and make a determination whether a
   resolicitation of proxies from its respective stockholders is appropriate.

Q: What stockholder approvals are required for approval of the merger? (see
   pages 38 and 41)

A. The holders of a majority of the shares of InfoSpace common stock (including
   the outstanding preferred stock which votes together with the common stock)
   present or represented by proxy at the stockholders' meeting must approve
   the issuance of InfoSpace common stock in the merger.

   The holders of a majority of the outstanding shares of Go2Net common stock
   (including shares of Go2Net preferred stock voting on an as-converted
   basis) and the holders of a majority of the Go2Net preferred stock (voting
   as a separate class) must adopt the merger agreement and approve the
   merger.

Q: Are there any stockholders already committed to voting in favor of the
   merger and the share issuance? (see pages 38 and 41)

A. Yes.

   . InfoSpace stockholders who collectively held approximately 24.1% of the
     outstanding InfoSpace common stock as of

                                       3
<PAGE>

     July 26, 2000 entered into voting agreements requiring them to vote all of
     their shares in favor of the issuance of InfoSpace common stock in the
     merger.

   . Go2Net stockholders who collectively held approximately 36.8% of the
     voting power of the Go2Net common stock (including shares of Go2Net
     preferred stock voting on an as-converted basis) outstanding as of
     July 26, 2000 entered into voting agreements requiring them to vote all
     of their shares in favor of adoption of the merger agreement.

Q: Who will be the directors of InfoSpace following the merger? (see page 65)

A. Following the merger, the board of directors of InfoSpace is expected to
   consist of five of the then current members of InfoSpace's board of
   directors, and Russell C. Horowitz, William D. Savoy and a designee of
   Messrs. Horowitz and Savoy acceptable to InfoSpace.

Q: Who will be the executive officers of InfoSpace following the merger?

A. Following the merger, the executive management team of InfoSpace is expected
   to include:

   . Naveen Jain, as Chairman;

   . Arun Sarin, as Vice Chairman and Chief Executive Officer;

   . Russell Horowitz, as Vice Chairman and President; and

   . Rand L. Rosenberg, as Chief Financial Officer.


          Our reasons for proposing the merger of InfoSpace and Go2Net

Q: Why are InfoSpace and Go2Net proposing the merger? (see page 44)

A. InfoSpace and Go2Net are proposing the merger to create an infrastructure
   services company to deliver an end-to-end integrated platform of
   applications and technologies for multiple platforms including narrowband
   and broadband PCs, TVs, personal digital assistants, pagers, cellular phones
   and other Web appliances.

Q: Does the board of directors of InfoSpace recommend voting in favor of
   issuing InfoSpace shares in the merger? (see page 46)

A. Yes. After careful consideration, InfoSpace's board of directors unanimously
   recommends that its stockholders vote in favor of the issuance of InfoSpace
   common stock to the stockholders of Go2Net in the merger.

Q: Does the board of directors of Go2Net recommend voting in favor of the
   merger agreement and the merger? (see page 48)

A. Yes. After careful consideration, Go2Net's board of directors unanimously
   recommends that its stockholders vote in favor of adoption of the merger
   agreement and the approval of the proposed merger.

Q: Do persons involved in the merger have interests which may conflict with
   mine? (see page 13)

A. Yes. When considering the recommendations of InfoSpace's and Go2Net's boards
   of directors, you should be aware that certain Go2Net directors and officers
   have interests in the merger that are different from, or are in addition to,
   yours. These interests include the employment of some Go2Net executive
   officers by InfoSpace after the merger, the appointment of some Go2Net
   directors to

                                       4
<PAGE>

   the InfoSpace board and the indemnification of directors and officers of
   Go2Net against certain liabilities both before and after the merger.

Q: Did InfoSpace's and Go2Net's financial advisors render favorable opinions
   concerning the merger? (see pages 50 and 56)

A. Yes.

   . In connection with the merger, InfoSpace's board of directors considered
     the opinion it received from the company's financial advisor, Morgan
     Stanley & Co. Incorporated, as to the fairness, from a financial point of
     view, to InfoSpace, of the exchange ratio provided for in the merger
     agreement.

   . Go2Net's board of directors considered the opinion it received from the
     company's financial advisor, Merrill Lynch Pierce Fenner & Smith
     Incorporated, as to the fairness, from a financial point of view, to the
     holders of Go2Net common stock, of the exchange ratio provided for in the
     merger agreement.

   . The full text of the written opinions of the financial advisors are
     attached to the back of this document as Annex B and Annex C, you should
     read them carefully in their entirety to understand the procedures
     followed, the assumptions made, matters considered and limitations on the
     review undertaken in providing the opinions. The opinion of Morgan
     Stanley & Co. Incorporated is directed to the InfoSpace board, and the
     opinion of Merrill Lynch is directed to the Go2Net board. These opinions
     do not address the prices at which InfoSpace's common stock will trade
     after the proposed merger and do not constitute a recommendation to any
     stockholder as to how to vote with respect to any matter relating to the
     proposed merger.

                             Steps for you to take

Q: What do I need to do now? (see page 38 or 41)

A. After carefully reading and considering the information contained in this
   joint proxy statement/prospectus, please mail your signed proxy card in the
   enclosed return envelope.

   If you do not include instructions on how to vote your properly signed
   proxy card, your common stock will be voted "FOR" approval of matters
   related to the merger.

   Your vote is important regardless of the number of shares that you own.

Q: Can I submit my proxy by telephone? (see page 40)

A. InfoSpace stockholders may be able to submit their proxy by telephone.
   InfoSpace stockholders should refer to the proxy card included with their
   materials for instructions about how to vote. If you vote by telephone, you
   do not need to complete and mail your proxy card.

Q: When and where will the vote take place? (see page 38 or 41)

A. Special meeting of InfoSpace stockholders. The InfoSpace special meeting
   will be held at the Hilton Bellevue located at 100 112th Avenue, Bellevue,
   Washington, 98004 on October 12, 2000, starting at 9:00 a.m., Pacific time.

   Special meeting of Go2Net stockholders. The Go2Net special meeting will be
   held at the Seattle Art Museum located at 100 University Street, Seattle,
   Washington, 98101 on October 12, 2000, starting at 9:00 a.m., Pacific time.

Q: Should I send in my Go2Net stock certificates now?

A. No. After the merger is completed, InfoSpace will send you written
   instructions for exchanging your Go2Net stock certificates for InfoSpace
   stock certificates.

                                       5
<PAGE>

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 by following the information provided to you by your broker.

Q: What do I do if I want to change my vote? (see page 38 or 41)

A. You can change your vote at any time before your proxy is voted at your
   special meeting. There are three ways for you to do this:

   1. Send written notice to the secretary of InfoSpace or Go2Net (as
      appropriate) that you wish to change or revoke your proxy,

   2. Sending a completed proxy bearing a later date than your original proxy
      prior to the vote at the special meeting, or

   3. Attend the stockholder meeting and vote in person.

Q: What happens if a Go2Net stockholder does not vote? (see page 42)

A. If a Go2Net stockholder fails to submit a proxy or vote at the special
   meeting, it will have the same effect as a vote against adoption of the
   merger agreement and approval of the merger.

   . If you return your proxy and do not indicate how you want to vote, your
     proxy will be counted as a vote to adopt the merger agreement and approve
     the merger.

   . If you submit a proxy and affirmatively elect to abstain from voting,
     your proxy will be counted as present for the purpose of determining the
     presence of a quorum but will not be voted at the special meeting.
     Consequently, your abstention will have the same effect as a vote against
     adoption of the merger agreement and approval of the merger.

Q: What happens if an InfoSpace stockholder doesn't vote? (see page 39)

A. If you are an InfoSpace stockholder and do not submit a proxy or vote at
   the special meeting, your shares will not be counted as present for
   purposes of determining the presence or absence of a quorum and will have
   no effect on the outcome of the proposal to approve the issuance of
   InfoSpace common stock in the merger.

   . If you submit a proxy and do not indicate how you want to vote, your
     proxy will be counted as a vote to approve the issuance of shares of
     InfoSpace common stock in connection with the merger.

   . If you submit a proxy and affirmatively elect to abstain from voting,
     your proxy will be counted as present for the purpose of determining the
     presence of a quorum but will not be voted at the special meeting.
     Consequently, your abstention will have the same effect as a vote against
     the issuance of InfoSpace's common stock in connection with the merger.

Q: Am I entitled to dissenters' or appraisal rights in connection with the
   merger? (see page 69)

A. No. Under Delaware law, neither stockholders of InfoSpace nor stockholders
   of Go2Net are entitled to dissenters' or appraisal rights in connection
   with the merger.

                           Other matters to consider

Q: How do the market prices of InfoSpace and Go2Net common stock compare?
   (see page 36)

A. Shares of InfoSpace common stock and Go2Net common stock are listed on the
   Nasdaq National Market. InfoSpace's trading symbol is "INSP," and Go2Net's
   trading symbol is "GNET." On July 26, 2000, the last full trading day prior
   to the public announcement of the proposed merger, the last reported sale
   prices were:

   . $47.75 per share of InfoSpace common stock, and

   . $60.5625 per share of Go2Net common stock.

   On September 5, 2000 the last reported sale prices were:

   . $43.1875 per share of InfoSpace common stock, and

   . $77.25 per share of Go2Net common stock.

   InfoSpace and Go2Net urge you to obtain current market quotations.

Q: What are the United States federal income tax consequences of the merger?
   (see page 66)

A. We expect that, in general, InfoSpace, Go2Net and Go2Net's stockholders will
   not recognize gain or loss for United States federal income tax purposes as
   a result of the merger, except for gain or loss attributable to cash
   received by Go2Net stockholders instead of fractional shares. It is a
   condition to the merger that both InfoSpace and Go2Net receive legal
   opinions to the effect that the merger will constitute a "reorganization"
   within the meaning of Section 368(a) of the Internal Revenue Code.

   Set forth in "The Merger--Material United States Federal Income Tax
   Considerations" is a description of the material current United States
   federal income tax consequences of the transaction. The tax consequences to
   each Go2Net stockholder will depend on the facts of that stockholder's own
   situation. Therefore, Go2Net stockholders are urged to consult their own
   tax advisors to determine their particular tax consequences.

Q: How will the merger be accounted for? (see page 68)

A. InfoSpace intends to account for the merger as a "pooling-of-interests" for
   financial accounting purposes, in accordance with accounting principles
   generally accepted in the United States of America. As a result, for
   accounting and financial reporting purposes, we will treat our companies as
   if they had always been one company.

Q: Does the merger agreement permit termination of the merger? (see page 77)

A. Yes. The merger agreement may be terminated by either InfoSpace or Go2Net
   prior to the effectiveness of the merger under some circumstances.

Q: Could payment of a termination fee be required in connection with the
   merger? (see page 78)

A. Yes. If the merger agreement is terminated upon some specified occurrences,
   Go2Net may be required to pay to InfoSpace a termination fee of
   $120,000,000. In addition, Go2Net granted InfoSpace an option to purchase
   the number of its shares of common stock equal to 19.9% of its shares
   outstanding as of July 26, 2000 for an exercise price of $84.28 per share.
   InfoSpace may exercise the option if specified events occur which give
   InfoSpace or Go2Net the right to terminate the merger agreement. However,
   the total profit that InfoSpace receives in connection with the termination
   fee and this option may not exceed $120,000,000.

                                       7
<PAGE>


Q: May Go2Net negotiate with other parties? (see page 73)

A. Generally, no. Go2Net agreed, subject to limited exceptions for responses
   to or negotiations in connection with unsolicited bona fide offers, not to
   initiate or engage in discussions with another party concerning a business
   combination with a party other than InfoSpace while the merger is pending.

Q: Are there restrictions on the ability to sell InfoSpace stock received as a
   result of the merger? (see page 69)

A. All InfoSpace common stock received by Go2Net stockholders in connection
   with the merger will be freely transferable unless the holder is considered
   an affiliate of either InfoSpace or Go2Net under the Securities Act of 1933,
   as amended. Shares of InfoSpace held by its affiliates may only be sold
   pursuant to a registration statement or an exemption from the registration
   requirements of the Securities Act.

   In addition, certain InfoSpace stockholders and Go2Net stockholders that
   will hold in the aggregate approximately 104,709,063 million shares of
   InfoSpace common stock following the merger have agreed not to sell or
   transfer such shares for a period ending on the date InfoSpace publicly
   announces financial results covering at least 30 days of combined operations
   of InfoSpace and Go2Net.

statement/prospectus. This joint proxy statement/prospectus contains forward-
looking statements that involve risks and uncertainties. InfoSpace and Go2Net

"intends," "may," "will," "should," "estimates," "predicts," "potential,"
"continue" and similar expressions to identify such forward-looking statements.
When used by InfoSpace or Go2Net in this joint proxy statement/prospectus,
these forward-looking statements include, but are not limited to statements
regarding:

   .  their business and growth strategy,

   .  the expected demand for and benefits of their services for their
      affiliates, advertisers, content providers and distribution partners,

   .  anticipated benefits from the businesses and technologies they have
      acquired or intend to acquire,

   .  future carriage fees,

   .  increased advertising and public relations expenditures,

   .  increased operating expenses and the reasons for such increases,

   .  expected operating losses,

   .  increased costs of revenues,

   .  increased product development expenses,

activity, performance, achievements and prospects to be materially different
from those expressed or implied by such forward-looking statements. These
risks, uncertainties and other factors include, among others, those identified
under "Risk Factors" and elsewhere in this joint proxy statement/prospectus.

                                  RISK FACTORS

  The merger involves a high degree of risk. By voting in favor of the merger
or the share issuance, as applicable, current Go2Net stockholders will be
choosing to invest in InfoSpace common stock, and current InfoSpace
stockholders will face dilution of their ownership interest in InfoSpace. An
investment in InfoSpace common stock involves a high degree of risk. In
addition to the other information contained in this joint proxy
statement/prospectus, you should carefully consider all of the following risk
factors relating to the proposed merger, the combined company, InfoSpace and
Go2Net in deciding whether to vote for the merger or the share issuance.

General Risks Related to the Merger

InfoSpace's stock price is volatile. The value of InfoSpace common stock issued
in the merger will depend on its market price at the time of the merger, and no
adjustment will be made as a result of changes in the market price of
InfoSpace's common stock.

  At the closing of the merger, each share of Go2Net common stock will be
exchanged for 1.82 shares of InfoSpace common stock. This exchange ratio will
not be adjusted for changes in the market price of InfoSpace common stock or
Go2Net common stock. In addition, neither InfoSpace nor Go2Net may terminate or
renegotiate the merger agreement, and Go2Net may not resolicit the vote of its
stockholders solely because of changes in the market price of InfoSpace common
stock or Go2Net common stock. Any reduction in InfoSpace's common stock price
will result in Go2Net stockholders receiving less value in the merger at
closing. Go2Net stockholders will not know the exact value of InfoSpace's
common stock to be issued to them in the merger at the time of the special
meeting of Go2Net stockholders.

  The market price of InfoSpace's common stock, like that of the shares of many
other technology and Internet companies, has been and is expected to continue
to be volatile. For example, since InfoSpace's initial public offering on
December 15, 1998, InfoSpace common stock traded as high as $138.50 per share
and as low as $1.88 per share.

  Recently, the stock market in general and the shares of Internet companies in
particular have experienced significant price fluctuations. The market price of
InfoSpace common stock is expected to continue to fluctuate significantly in
response to various factors, including:

  . actual or anticipated variations in quarterly results of operations;

  . the addition or loss of affiliates or content providers;

  . announcements of technological innovations, new products or services by
    InfoSpace or its competitors;

  . changes in financial estimates or recommendations by securities analysts;

  . conditions or trends in the Internet and online commerce industries;

  . changes in the market valuations of other Internet, online service or
    software companies;

  . InfoSpace's announcements of significant acquisitions, strategic
    partnerships, joint ventures or capital commitments;

  . additions or departures of key personnel;

  . sales of its common stock;

  . general market conditions; and

  . other events or factors, many of which are beyond InfoSpace's control.

  In addition, the stock market in general, and the Nasdaq National Market and
the market for Internet and technology companies in particular, have
experienced extreme price and volume fluctuations that have

                                       10
<PAGE>

often been unrelated or disproportionate to the operating performance of these
companies. These broad market and industry factors may materially and adversely
affect InfoSpace's stock price, regardless of its operating performance.

InfoSpace will face significant challenges in integrating InfoSpace and Go2Net
and, as a result, may not realize the expected benefits of the merger.
  Integrating the operations, systems and personnel of InfoSpace and Go2Net
will be a complex process, and InfoSpace is uncertain that the integration will
be completed in a timely manner or will achieve the anticipated benefits of the
merger. The challenges involved in this integration include:

  . retaining existing customers and strategic partners of each company;

  . retaining and integrating management and other key employees of both
    InfoSpace and Go2Net;

  . coordinating research and development activities to enhance introduction
    of new products, services and technologies;

  . combining product and service offerings effectively and quickly;

  . transitioning all systems to a common information technology system;

  . persuading employees that the business cultures of InfoSpace and Go2Net
    are compatible;

  . offering products and services of InfoSpace and Go2Net to each other's
    customers and partners;

  . bringing together the companies' marketing efforts so that the industry
    receives useful information about the merger; and

  . developing and maintaining uniform standards, controls, procedures and
    policies.

  It is not certain that InfoSpace and Go2Net can be successfully integrated in
a timely manner or at all or that any of the anticipated benefits will be
realized. Risks to successful integration of the companies include:

  . the impairment of relationships with employees, customers and business
    partners as a result of the integration of management and other key
    personnel;

  . the potential disruption of InfoSpace's ongoing business and distraction
    of its management;

  . the difficulty of incorporating acquired technology and rights into the
    product and service offerings of InfoSpace; and

  . unanticipated expenses related to integration of the two companies.

  InfoSpace may not succeed in addressing these risks or any other problems
encountered in connection with the merger. The diversion of the attention of
InfoSpace's management and any difficulties encountered in the process of
combining the companies could cause the disruption of, or a loss of momentum
in, the activities of InfoSpace's business. Further, neither InfoSpace nor
Go2Net can assure you that the growth rate of the combined company will equal
the historical growth rates experienced by InfoSpace or Go2Net.

If InfoSpace does not successfully integrate Go2Net or the merger's benefits do
not meet the expectations of investors or financial or industry analysts, the
market price of InfoSpace common stock may decline.

  The market price of InfoSpace common stock may decline as a result of the
merger if:

  . the combined company is unable to obtain additional capital on acceptable
    terms when required;

  . the integration of InfoSpace and Go2Net is not completed in a timely and
    efficient manner;

                                       11
<PAGE>

  . InfoSpace does not achieve the benefits of the merger as rapidly as, or
    to the extent, anticipated by financial or industry analysts;

  . InfoSpace's assumptions about Go2Net's business model and operations,
    considered on a stand-alone basis, such as the ability of Go2Net to
    distribute applications and infrastructure technologies through
    narrowband and broadband platforms and to continue to execute its
    strategic plan, prove incorrect, thereby requiring additional capital to
    fund the operating losses of such facilities;

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

  . significant stockholders of InfoSpace following the merger decide to
    dispose of their shares because the results of the merger are not
    consistent with their expectations.

Failure to complete the merger could negatively impact the market price of
Go2Net common stock and InfoSpace common stock.

  If the merger is not completed for any reason, Go2Net and InfoSpace will be
subject to a number of material risks, including:

  . the provision in the merger agreement that Go2Net could be required to
    pay InfoSpace a termination fee in the amount of $120 million;

  . the market price of Go2Net common stock and InfoSpace common stock may
    decline to the extent that the current market price of such shares
    reflects a market assumption that the merger will be completed;

  . costs related to the merger, such as legal and accounting fees and a
    portion of the investment banking fees, must be paid even if the merger
    is not completed;

  . benefits that InfoSpace expects to realize from the merger, such as the
    potentially enhanced financial and competitive position of the combined
    company, would not be realized;

  . Go2Net stockholders may experience dilution to their stock ownership
    because the stock option granted to InfoSpace by Go2Net may become
    exercisable;

  . Go2Net may no longer qualify as an entity that may be a party to a
    business combination for which pooling-of-interests accounting would be
    available; and

  . the diversion of management attention from the day-to-day business of
    Go2Net, the scaling back of marketing and capital spending and the
    unavoidable disruption to its employees and its relationships with
    customers and suppliers, during the period before consummation of the
    merger, may make it difficult for Go2Net to regain its financial and
    market position if the merger does not occur.

  If the merger is terminated and the Go2Net board of directors seeks another
merger or business combination, Go2Net stockholders cannot be certain that
Go2Net will be able to find a partner willing to pay an equivalent or more
attractive price than the price to be paid by InfoSpace in the merger.

During the pendency of the merger, Go2Net may not be able to enter into a
merger or business combination with another party at a favorable price because
of restrictions in the merger agreement.

  Until the merger is completed or the merger agreement is terminated, subject
to specified exceptions, Go2Net is prohibited from entering into or soliciting,
initiating or encouraging any inquiries or proposals that may lead to a
proposal or offer for a merger, consolidation, business combination, sale of
substantial assets, tender offer, sale of shares of capital stock or other
similar transactions with any person or entity other than InfoSpace. As a
result of these prohibitions, Go2Net may not be able to enter into an
alternative transaction at a favorable price.

                                       12
<PAGE>

Go2Net's officers and directors have conflicts of interest that may influence
them to support or approve the merger.

  The directors and officers of Go2Net participate in arrangements and have
continuing indemnification against liabilities that provide them with interests
in the merger that are different from, or in addition to, those of other Go2Net
stockholders, including the following:

  . directors and officers and their respective affiliates, representing a
    significant percentage of Go2Net stockholders, have agreed to vote in
    favor of the merger agreement and the merger;

  . upon completion of the merger, two current Go2Net directors, Russell C.
    Horowitz and William D. Savoy, and their designee acceptable to
    InfoSpace, will become directors of InfoSpace;

  . upon completion of the merger, the current chairman and chief executive
    officer of Go2Net, Russell C. Horowitz, will become vice chairman and
    president of InfoSpace;

  . upon completion of the merger, InfoSpace may enter into employment
    agreements with some executive officers of Go2Net; and

  . InfoSpace has agreed to cause the surviving corporation in the merger to
    indemnify each present and former Go2Net officer and director against
    liabilities arising out of such person's services as an officer or
    director. InfoSpace will cause the surviving corporation to maintain
    officers' and directors' liability insurance to cover any such
    liabilities for the next six years.

  The directors and officers of Go2Net may therefore have been and may be more
likely to vote to adopt the merger agreement and approve the merger than if
they did not have these interests. Go2Net stockholders should consider whether
these interests may have influenced these directors and officers to support or
recommend the merger. You should read more about these interests under "The
Merger--Interests of Certain Persons in the Merger" on page 65.

Uncertainties associated with the merger may cause Go2Net to lose key
personnel.

  Current and prospective Go2Net employees may experience uncertainty about
their future roles with InfoSpace. This uncertainty may adversely affect
Go2Net's ability to attract and retain key management, sales, marketing and
technical personnel.

The merger could adversely affect combined financial results.

  InfoSpace and Go2Net expect to incur direct transaction costs of
approximately $35.0 million in connection with the merger. If the benefits of
the merger do not exceed the costs associated with the merger, including any
dilution to InfoSpace stockholders resulting from the issuance of shares in
connection with the merger, InfoSpace's financial results, including earnings
per share, could be adversely affected. In addition, if the merger is not
accounted for as a pooling-of-interests, the combined company could experience
significant adverse impact to its net income due to the amortization of
goodwill and other intangibles in light of the impact of purchase accounting
for the merger.

Failure to qualify for pooling-of-interests accounting treatment may harm the
future operating results of the combined company.

  If, after completion of the merger, events occur that cause the merger to
fail to qualify for pooling-of-interests accounting treatment, the purchase
method of accounting would apply. Purchase accounting treatment would harm the
reported operating results of the combined company. Under purchase accounting,
InfoSpace would record the estimated fair value of InfoSpace common stock
issued in the merger as the cost of the merger. A portion of the purchase price
would be charged to in process research and development expense. The remainder
would be allocated to the net assets acquired, with the excess of the estimated
fair

                                       13
<PAGE>

value of InfoSpace common stock issued in the merger over the fair value of net
assets acquired recorded as goodwill or other intangible assets. This goodwill
would be amortized in future periods. The estimated fair value of the InfoSpace
common stock to be issued in the merger is much greater than the historical net
book value at which Go2Net carries assets in its accounts.

InfoSpace and Go2Net may not be able to obtain the required regulatory
approvals for completion of the merger.

  InfoSpace and Go2Net must obtain, as a condition to their obligation to
complete the merger, clearance under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976. On August 23, 2000, early termination of the waiting
period was granted to InfoSpace and Go2Net. Even though early termination was
granted, any federal, state or foreign governmental agency or private person
may challenge the merger at any time before or after its completion.

Risks Relating to InfoSpace

  InfoSpace operates in a rapidly emerging environment that involves many
risks, some of which are beyond InfoSpace's control. The following discussion
highlights some of these risks. In the following discussion of risks relating
to InfoSpace, references to "we," "us," "our" and "ours" refer to InfoSpace and
its consolidated subsidiaries.

We have a limited operating history and a history of losses.

  We have a limited operating history, which makes it difficult to evaluate our
business and prospects. We have incurred net losses from our inception in March
1996 through June 30, 2000. At June 30, 2000, we had an accumulated deficit of
approximately $213.5 million. We expect to incur operating losses on a
quarterly basis in the future. Our prospects must be considered in light of the
risks, expenses and difficulties frequently encountered by companies in their
early stage of development, particularly companies in new and rapidly evolving
markets such as Internet services. To address the risks we face and to be able
to achieve and sustain profitability, we must, among other things:

  . develop and maintain strategic relationships with potential affiliates,
    distribution partners and content providers;

  . identify and acquire the rights to additional content, technology and
    services;

  . successfully integrate new features with our consumer, merchant and
    wireless services;

  . expand our sales and marketing efforts, including relationships with
    third parties to sell our merchant services;

  . successfully expand into international markets;

  . retain and motivate qualified personnel; and

  . successfully respond to competitive developments.

  If we do not effectively address the risks we face, our business will suffer
and we may not sustain profitability. See "InfoSpace Selected Consolidated
Financial Data" and "InfoSpace Management's Discussion and Analysis of
Financial Condition and Results of Operations."

Our financial results are likely to fluctuate.

  Our financial results have varied on a quarterly basis and are likely to
fluctuate substantially in the future. These fluctuations may be caused by
several factors, many of which are beyond our control. These factors include:

  . the addition or loss of affiliates;

                                       14
<PAGE>

  . variable demand for our consumer, merchant and wireless services by our
    affiliates and distribution providers;

  . the cost of acquiring and the availability of content, technology and
    services;

  . the growth and overall level of demand for consumer, merchant and
    wireless services;

  . our ability to attract and retain advertisers, content providers,
    affiliates and distribution partners;

  . seasonal trends in Internet usage and advertising placements;

  . the amount and timing of fees we pay to our affiliates to include our
    information services on their Web sites and wireless devices;

  . the productivity of our direct sales force and the sales forces of our
    distribution partners;

  . the amount and timing of increased expenditures for expansion of our
    operations, including the hiring of new employees, capital expenditures
    and related costs;

  . our ability to continue to enhance, maintain and support our technology;

  . the result of litigation that is currently ongoing against InfoSpace, or
    any litigation that is filed against us in the future;

  . our ability to attract and retain personnel;

  . our ability to successfully integrate and manage newly acquired
    companies;

  . the introduction of new or enhanced services by us, our affiliates or
    distribution partners, or other companies that compete with us or our
    affiliates;

  . price competition or pricing changes in Internet information
    infrastructure services, such as ours;

  . technical difficulties, system downtime, system failures or Internet
    brown-outs;

  . political or economic events and governmental actions affecting Internet
    operations or content; and

  . general economic conditions and economic conditions specific to the
    Internet.

  If one or more of these factors or other factors occur, our business could
suffer.

  In addition, because InfoSpace only began operations in March 1996, and
because the market for Internet infrastructure services such as ours is new and
evolving, it is very difficult to predict future financial results. As a result
of our recent acquisitions and continued global expansion, we have
significantly increased our sales and marketing, research and development and
general and administrative expenses and intend to continue to do so for the
remainder of the year 2000. Our expenses are partially based on our
expectations regarding future revenues and estimated expenses from our
acquisitions, which are largely fixed in nature, particularly in the short
term. As a result, if our revenues in a period do not meet our expectations,
our financial results will likely suffer.

Pending and potential acquisitions involve risks.

  We have acquired complementary technologies or businesses in the past, and
intend to do so in the future. Acquisitions may involve potentially dilutive
issuances of stock, the incurrence of additional debt and contingent
liabilities or large one-time write-offs and amortization expenses related to
goodwill and other intangible assets. Any of these factors could adversely
affect our results of operations or stock price. Acquisitions involve numerous
risks, including:

  . difficulties in assimilating the operations, products, technology,
    information systems and personnel of the acquired company;

  . diverting management's attention from other business concerns;

                                       15
<PAGE>

  . impairing relationships with our employees, affiliates, content providers
    and distribution partners;

  . being unable to maintain uniform standards, controls, procedures and
    policies;

  . entering markets in which we have no direct prior experience; and

  . losing key employees of the acquired company.

  We may not be able to successfully integrate the technology and personnel we
have acquired or the other businesses, technologies or personnel that we
acquire in the future. We and the businesses acquired by us may require
substantial additional capital, and there can be no assurance as to the
availability of such capital when needed, nor as to the terms on which such
capital might be made available to us. We have retained, and may in the future
retain, existing management of acquired companies or technologies, under the
overall supervision of our senior management. The success of the operations of
these acquired companies and technologies will depend, to a great extent, on
the continued efforts of the management of the acquired companies.

We need to manage our growth and maintain procedures and controls.

  We have rapidly and significantly expanded our operations and anticipate
further significant expansion to accommodate expected growth in our customer
base and market opportunities. We have increased the number of employees from
15 at January 1, 1998 to 502 at June 30, 2000. We now have offices in Bellevue,
Washington; San Francisco, San Mateo and Mountain View, California; New York
City and Rochester, New York; Toronto and Ottawa, Canada; Papendrecht,
Netherlands; London, United Kingdom, and recently established offices in
Australia and Brazil. This expansion has placed, and is expected to continue to
place, a significant strain on our management and operational resources. We do
not have experience managing multiple offices with multiple facilities and
personnel in disparate locations. As a result, we may not be able to
effectively manage our resources, coordinate our efforts, supervise our
personnel or otherwise successfully manage our resources. We have recently
added a number of key managerial, technical and operations personnel and we
expect to add additional key personnel in the near future. We also plan to
continue to significantly increase our employee base. These additional
personnel may further strain our management resources.

  Our relationships with affiliates and distribution partners, content
providers and advertisers are subject to frequent change. Prior to implementing
procedures and controls in this area, these changes were often informal. In
particular, we may have failed to perform our obligations under certain
commercial contracts that may have been modified or terminated by verbal
agreement. We believe that any failure to perform our obligations was not
significant. This practice of the modification or termination of past written
agreements by verbal agreement has resulted, and may result in the future, in
disputes regarding the existence, interpretation and circumstances regarding
modification or termination of commercial contracts. If our relationships with
affiliates and distribution partners, content providers and advertisers evolve
in an adverse manner, if we get into contractual disputes with affiliates and
distribution partners, content providers or advertisers or if any agreements
with such persons are terminated, our business could suffer. See "InfoSpace
Business--Legal Proceedings."

  The rapid growth of our business has strained our ability to meet customer
demands and manage the growing number of affiliate relationships. In addition,
our affiliate relationships are also growing in their size and complexity of
services. As a result of the growth in the size, number, and complexity of our
relationships we may be unable to meet the demands of our customer
relationships, which could result in the loss of customers, subject us to
penalties under our affiliate agreements and harm our business reputation.

  To manage the expected growth of our operations and personnel, we must
continue maintaining and improving or replacing existing operational,
accounting and information systems, procedures and controls. Further, we must
manage effectively our relationships with various Internet content providers,
distribution partners, wireless carriers, advertisers, affiliates and other
third parties necessary to our business. If we are

                                       16
<PAGE>

unable to manage growth effectively, our business could suffer. See "--We are
subject to pending legal proceedings" and "InfoSpace Management's Discussion
and Analysis of Financial Condition and Results of Operations."

We depend on third parties for content.

  We typically do not create our own content. Rather, we acquire rights to
information from more than 85 third-party content providers, and our future
success is critically dependent upon our ability to maintain relationships with
these content providers and enter into new relationships with other content
providers.

  We typically license content under short-term arrangements that do not
require us to pay royalties or other fees for the use of the content. However,
we do enter into revenue-sharing arrangements with certain content providers,
and we pay certain content providers a one-time fee, a periodic fee or a fee
for each query from Web users. In the future, we expect that certain of our
content providers will likely demand a greater portion of advertising revenues
or increase the fees that they charge us for their content. If we fail to enter
into and maintain satisfactory arrangements with content providers, our
business will suffer. See "--We need to manage our growth and maintain
procedures and controls."

We depend on key personnel.

  Our performance depends on the continued services of our executive officers
and other key personnel, particularly within our merchant services and wireless
services business areas. We maintain key person life insurance on Naveen Jain,
our Chairman, in the amount of $5.0 million. We do not maintain key person life
insurance policies on any of our other employees. If we lose the services of
any of our executive officers or other key employees, our business could
suffer. See "InfoSpace Business--Employees" and "InfoSpace Management--
Executive Officers and Directors."

We need to hire additional personnel.

  Our future success depends on our ability to identify, attract, hire, train,
retain and motivate highly skilled technical, managerial, sales and marketing
and business development personnel. We intend to hire a significant number of
technical, sales and marketing, business development and administrative
personnel during the next year. Our services and the industries to which we
provide our services are relatively new, particularly with respect to our
wireless and merchant services. As a result, qualified technical personnel with
relevant experience to our business are scarce and therefore difficult to
recruit. If we fail to successfully attract, assimilate and retain a sufficient
number of qualified technical, managerial, sales and marketing, business
development and administrative personnel, our business could suffer.

Our international expansion plans involve risks.

  A key component of our strategy is expanding our operations into
international markets. We have entered into a joint venture agreement with
Thomson Directories Limited to replicate our infrastructure services in Europe.
The joint venture, TDL InfoSpace (Europe) Limited, launched content services in
the United Kingdom in the third quarter of 1998. On August 31, 2000, we
acquired all of the issued and outstanding stock of TDLI.com Limited. This gave
us complete control of TDL InfoSpace. In March 1999, we began providing
infrastructure services to Canadian affiliates through our wholly-owned
subsidiary, InfoSpaceCanada.com. We expect to launch InfoSpace.com India to
provide comprehensive localized consumer, merchant and wireless services to the
Indian market. In addition, with our acquisition of Saraide, we have begun to
expand our wireless services into Europe, Japan and Canada. We have also
entered into agreements to expand our services into Brazil, China and Australia
and are currently investigating other international opportunities.

  To date, we have limited experience in developing and syndicating localized
versions of our information infrastructure services internationally, and we may
not be able to successfully execute our business model in

                                       17
<PAGE>

these markets. In addition, international markets experience lower levels of
Internet usage and Internet advertising than the United States. We rely on our
business partner in Europe for U.K. directory information and local sales
forces and may enter into similar relationships if we expand into other
international markets. Accordingly, our success in these markets will be
directly linked to the success of our business partners in such activities. If
our business partners fail to successfully establish operations and sales and
marketing efforts in these markets, our business could suffer. See "InfoSpace
Business--International Expansion."

  In addition, we face a number of risks inherent in doing business in
international markets, including, among others:

  . unexpected changes in regulatory requirements;

  . potentially adverse tax consequences;

  . export controls relating to encryption technology;

  . tariffs and other trade barriers;

  . difficulties in staffing and managing foreign operations;

  . changing economic conditions;

  . exposures to different legal standards (particularly with respect to
    intellectual property, data privacy, distribution of information over the
    Internet and employment laws);

  . burdens of complying with a variety of foreign laws;

  . fluctuations in currency exchange rates; and

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

  If any of these risks occur, our business could suffer.

Our business is highly competitive.

  We operate in the Internet information infrastructure services market, which
is extremely competitive and is rapidly changing. Our current and prospective
competitors include many large companies that have substantially greater
resources than we have.

  Some of the companies we compete with are currently customers of ours, the
loss of which could harm our business. We may also face increased competition
from traditional media companies expanding onto the Internet. Many of our
current customers have established relationships with certain of our current
and potential future competitors. If our competitors develop Internet
information infrastructure services that are superior to ours or that achieve
greater market acceptance than ours, our business will suffer. For a
description of our competitors and competitive factors in our industry, see
"InfoSpace Business--Competition."

Our business relies on the performance of our systems.

  Our success depends, in part, on the performance, reliability and
availability of our consumer, merchant and wireless services. Our revenues
depend, in large part, on the number of users that access our consumer,
merchant and wireless services. We are currently transitioning our computer and
communications hardware from our former headquarters in Redmond, Washington to
our new headquarters in Bellevue, Washington.

  With the acquisitions of Prio and Saraide, we have data centers in Mountain
View, California serving the promotions technology and Papendrecht, Netherlands
serving wireless customers in Europe. None of

                                       18
<PAGE>

our data centers are currently redundant. Our success on a global basis will
depend in part on our ability to create carrier class infrastructure systems
and build network operations centers worldwide that can support the delivery of
integrated consumer, merchant and wireless services and the expected growth of
these services. We may be unable to develop or successfully manage the
infrastructure necessary to meet current or future demands for reliability and
scalability of our systems.

  The Company has entered into Service Level Agreements with certain merchant
services distributors including merchant banks and most of our wireless
customers. These agreements call for system up times and 24/7 support, and
include penalties for non-performance. We may be unable to fulfill these
commitments, which could subject us to penalties under our agreements, harm our
reputation and result in the loss of customers and distributors, which would
harm our business.

  Our systems and operations could be damaged or interrupted by fire, flood,
power loss, telecommunications failure, Internet breakdown, break-in,
earthquake and similar events. We do not have a formal disaster recovery plan,
and we do not carry business interruption insurance that is adequate to
compensate us for all the losses that may occur. In addition, systems that use
sophisticated software may contain bugs, which could also interrupt service.
Any system interruptions resulting in the unavailability of our consumer,
merchant and wireless services would reduce the volume of users able to access
our consumer, merchant and wireless services and the attractiveness of our
service offerings to our affiliates, advertisers and content providers, which
could harm our business.

We rely on advertising and transaction revenues.

  We have derived a significant amount of our revenues from the sale of
national and local advertisements, and transaction fees from our affiliates who
use our consumer services, and we expect this to continue into the third
quarter of 2000. Our ability to increase and diversify our revenues will depend
upon a number of factors, including the following:

  . the acceptance of the Internet as an advertising medium by national and
    local advertisers;

  . the acceptance and regular use of our information infrastructure services
    by a large number of users who have demographic characteristics that are
    attractive to advertisers;

  . the availability of attractive advertising space within our private label
    solutions;

  . the ability of our business development and sales personnel to
    effectively sell our broad suite of consumer, merchant and wireless
    services;

  . the development of the Internet as an attractive platform for electronic
    commerce;

  . the use of our integrated merchant tools by small and medium sized online
    and offline merchants;

  . the adoption of our wireless services and solutions by wireless carriers
    and device manufacturers; and

  . the use of our information services by subscribers on their wireless
    devices.

  Our ability to maintain or increase our advertising revenues will also be
affected by changes in fee levels and structures. Many of our advertising
contracts provide for fees to be paid for us on a cost per thousand impressions
(CPM) basis. If CPMs decrease in future contracts, or we fail to provide
required minimum levels of user impressions, our revenue growth may slow or
revenues may even decrease.

We rely on our relationships with affiliates.

  We will be able to continue generating revenues from advertising, transaction
fees and promotions only if we can secure and maintain distribution for our
information infrastructure services on acceptable commercial terms through a
wide range of affiliates. In particular, we expect that a limited number of our
affiliates, including America Online, Inc., its CompuServe and Digital City
divisions and its Netscape

                                       19
<PAGE>

Communications subsidiary and Microsoft Network, LLC, will account for a
substantial portion of our affiliate traffic. Our distribution arrangements
with our affiliates typically are for limited durations of between six months
and two years and automatically renew for successive terms thereafter, subject
to termination on short notice. We cannot assure you that such arrangements
will not be terminated or that such arrangements will be renewed upon
expiration of their terms. We generally share with each affiliate a portion of
the revenues generated by advertising on the Web pages that deliver our
content services. We pay carriage fees to certain affiliates, including AOL.
These relationships may not be profitable or result in benefits to us that
outweigh the costs of the relationships. In addition, if we lose a major
affiliate, we may be unable to timely or effectively replace the affiliate
with other affiliates with comparable traffic patterns and user demographics.
The loss of any major affiliate could harm our business.

Our affiliates may be unable to raise sufficient capital or may experience
adverse business conditions.

  As a result of unfavorable conditions in the public equity markets, some of
our affiliates may have difficulty raising sufficient capital to support their
long-term operations. As a result, these affiliates may not be able to pay us
some or all of the fees they are required to pay us under their existing
agreements. In addition, our affiliates may experience adverse business
conditions due to market conditions, industry conditions or other factors,
which may render them unable to fulfill their contractual obligations to us.
Such conditions may also prevent potential affiliates to enter into
contractual relationships or other strategic business relationships with us.

We rely on a small number of customers.

  We derive a substantial portion of our revenues from a small number of
customers. We expect that this will continue in the foreseeable future.

  Our top ten customers represented 53% of our revenues in the first six
months of 2000 and 57% of our revenues for fiscal year 1999. In particular,
Knight Ridder, Inc. and 800-U.S. Search, Inc. each accounted for approximately
11% of our revenues for the six months ended June 30, 2000, and 800-U.S.
Search, Inc. accounted for approximately 21% of our revenues for the year
ended December 31, 1999. If we lose any of these customers, or if any of these
customers are unable or unwilling to pay us amounts that they owe us, our
financial results will suffer.

Our industry is experiencing consolidation.

  The Internet industry has recently experienced substantial consolidation.
For example, AOL has acquired Netscape and has agreed to acquire Time Warner,
At Home has acquired Excite, and Compaq has
acquired ZIP2. We expect this consolidation to continue. These acquisitions
could affect us in a number of ways, including:

  . companies from whom we acquire content could be acquired by one of our
    competitors and stop licensing us content;

  . our customers could be acquired by one of our competitors and terminate
    their relationship with us; and

  . our customers could merge with other customers, which could reduce the
    size of our customer base.

  This consolidation in the Internet industry could harm our business.

We rely on internally developed software and systems.

  We have developed custom software for our network servers and our private
label solutions. This software may contain undetected errors, defects or bugs.
Although we have not suffered significant harm

                                      20
<PAGE>

from any errors or defects to date, we may discover significant errors or
defects in the future that we may or may not be able to fix. We must expand and
upgrade our technology, transaction-processing systems and network
infrastructure if the volume of traffic on our Web site or our affiliates' Web
sites increases substantially. In addition, as we continue to expand our
merchant and wireless services, we may have to significantly modify our
systems. We could experience periodic temporary capacity constraints, which may
cause unanticipated system disruptions, slower response times and lower levels
of customer service. We may be unable to accurately project the rate or timing
of increases, if any, in the use of our consumer, merchant and wireless
services or expand and upgrade our systems and infrastructure to accommodate
these increases in a timely manner. Any inability to do so could harm our
business.

Rapid technological change affects our business.

  Rapidly changing technology, evolving industry standards, evolving customer
demands and frequent new product and service introductions characterize our
market. Our market's early stage of development exacerbates these
characteristics. Our future success depends in significant part on our ability
to develop and introduce compelling services on a timely and competitive basis
and to improve the performance, content and reliability of our consumer,
merchant and wireless services in response to both the evolving demands of the
market and competitive product offerings. Our efforts in these areas may not be
successful. If a large number of affiliates adopt new Internet technologies or
standards, we may need to incur substantial expenditures modifying or adapting
our enabling technologies and Internet information infrastructure services.

We rely on the Internet system infrastructure.

  Our success depends, in large part, on other companies maintaining the
Internet system infrastructure. In particular, we rely on other companies to
maintain a reliable network backbone that provides adequate speed, data
capacity and security and to develop products that enable reliable Internet
access and services. If the Internet continues to experience significant growth
in the number of users, frequency of use and amount of data transmitted, the
Internet system infrastructure may be unable to support the demands placed on
it, and the Internet's performance or reliability may suffer as a result of
this continued growth. In addition, the Internet could lose its commercial
viability as a form of media due to delays in the development or adoption of
new standards and protocols to process increased levels of Internet activity.
Any such degradation of Internet performance or reliability could cause
advertisers to reduce their Internet expenditures. If other companies do not
develop the infrastructure or complementary products and services necessary to
establish and maintain the Internet as a viable commercial medium, or if the
Internet does not become a viable commercial medium or platform for
advertising, promotions and electronic commerce, our business could suffer.

We receive information that may subject us to liability.

  We obtain content and commerce information from third parties. When we
integrate and distribute this information over the Internet, we may be liable
for the data that is contained in that content. This could subject us to legal
liability for such things as defamation, negligence, intellectual property
infringement and product or service liability. Many of the agreements by which
we obtain content do not contain indemnity provisions in favor of us. Even if a
given contract does contain indemnity provisions, these provisions may not
cover a particular claim. We carry general business insurance, however, this
coverage may be inadequate.

  In addition, individuals whose names appear in our yellow pages and white
pages directories have occasionally contacted us. These individuals believed
that their phone numbers and addresses were unlisted, and our directories are
not always updated to delete phone numbers or addresses when they are changed
from listed to unlisted. While we have not received any claims from these
individuals, we may receive claims in the future. Any liability that we incur
as a result of content we receive from third parties could harm our financial
results.

                                       21
<PAGE>

  We also gather personal information from users in order to provide
personalized services. Gathering and processing this personal information may
subject us to legal liability for negligence, defamation, invasion of privacy,
product or service liability. We may also be subject to laws and regulations,
both in the United States and abroad, regarding user privacy. See "InfoSpace
Business--Governmental Regulation."

We may become subject to governmental regulation.

  Because of the increasing use of the Internet, the government may adopt laws
and regulations with regard to the Internet covering issues such as user
privacy, pricing, content, taxation, copyrights, distribution and product and
services quality. For a description of certain risks relating to government
regulation, see "InfoSpace Business--Governmental Regulation."

Our networks face security risks.

  Even though we have implemented security measures, our wireless and wireline
networks may be vulnerable to unauthorized access by hackers or others,
computer viruses and other disruptive problems. Someone who is able to
circumvent security measures could misappropriate our proprietary information
or cause interruptions in our Internet operations. Internet and online service
providers have in the past experienced, and may in the future experience,
interruptions in service as a result of the accidental or intentional actions
of Internet users, current and former employees or others. Our wireless
Internet services may present additional security risks that could lead to
interruptions in services, security breaches and related problems. We may need
to expend significant capital or other resources protecting against the threat
of security breaches or alleviating problems caused by breaches. Although we
intend to continue to implement industry-standard security measures, persons
may be able to circumvent the measures that we implement in the future.
Eliminating computer viruses and alleviating other security problems may
require interruptions, delays or cessation of service to users accessing Web
pages that deliver our content services, any of which could harm our business.
See "InfoSpace Business--Technology and Infrastructure--Data Network
Infrastructure."

  Users of online commerce services are highly concerned about the security of
transmissions over public networks. Concerns over security and the privacy of
users may inhibit the growth of the Internet and other online services
generally, and the Web in particular, especially as a means of conducting
commercial transactions. As we expand our merchant services, we intend to rely
on encryption and authentication technology licensed from third parties to
provide the security and authentication necessary to securely transmit
confidential information, such as member profiles and customer credit card
numbers. Users could possibly circumvent the measures we take to protect
customer transaction data. To the extent that our activities involve the
storage and transmission of proprietary information, such as credit card
numbers, security breaches could damage our reputation and expose us to a risk
of loss or litigation and possible liability. Any compromise of our security
could harm our business.

We may be unable to adequately protect or enforce our intellectual property
rights.

  Our success depends significantly upon our proprietary technology. To protect
our proprietary rights, we rely on a combination of copyright and trademark
laws, patents, trade secrets, confidentiality agreements with employees and
third parties and protective contractual provisions. Despite our efforts to
protect our proprietary rights, unauthorized parties may copy aspects of our
products or services or obtain and use information that we regard as
proprietary. In addition, others could possibly independently develop
substantially equivalent intellectual property. If we do not effectively
protect our intellectual property, our business could suffer.

  Companies in the computer industry have frequently resorted to litigation
regarding intellectual property rights. We may have to litigate to enforce our
intellectual property rights, to protect our trade

                                       22
<PAGE>


secrets or to determine the validity and scope of other parties' proprietary
rights. From time to time, we have received, and we may receive in the future,
notice of claims of infringement of other parties' proprietary rights. Any such
claims could be time-consuming, result in costly litigation, divert
management's attention, cause product or service release delays, require us to
redesign our products or services or require us to enter into royalty or
licensing agreements. These royalty or licensing agreements, if required, may
not be available on acceptable terms or at all. If a successful claim of
infringement were made against us and we could not develop non-infringing
technology or license the infringed or similar technology on a timely and cost-
effective basis, our business could suffer. See "InfoSpace Business--
Intellectual Property" and "InfoSpace Business--Legal Proceedings."

We are subject to pending legal proceedings.

  From time to time we have been, and expect to continue to be, subject to
legal proceedings and claims in the ordinary course of our business, including
claims of alleged infringement of third-party trademarks and other intellectual
property rights by us. Such claims, even if not meritorious, could require the
expenditure of significant financial and managerial resources, which could harm
our business.

  On February 8, 2000, we reached a settlement with an alleged former employee.
Under the terms of the settlement, we paid the alleged employee a cash payment
of $10.5 million.

  On December 15, 1999, a former employee filed a complaint against us alleging
claims for breach of contract, fraud, negligent misrepresentation, and
promissory estoppel. The former employee contends he agreed to work for us on
the basis of certain misrepresentations, that he entered into an agreement with
us that entitles him to an option to purchase 300,000 shares of our common
stock, and that he was terminated without cause. The former employee is seeking
the right to purchase the shares of stock, unspecified compensatory and
punitive damages, and litigation costs and attorney's fees.

  On December 23, 1998, we filed a complaint against Internet Yellow Pages,
Inc., or IYP, and Greg Crane, asserting claims for (a) account stated, (b)
breach of contract, and (c) fraud. IYP has asserted counterclaims against us
for breach of contract, fraud, extortion and violation of the Washington
Consumer Protection Act, and seeks relief consisting of $1,500,000 and other
unquantified money damages, punitive damages, treble damages and attorney's
fees.

  We believe we have meritorious defenses to all of these claims against us.
Nevertheless, litigation is inherently uncertain, and we may not prevail in
these suits.

  We had discussions with a number of individuals in the past regarding
employment by us and also hired and subsequently terminated a number of
individuals as employees or consultants. Furthermore, primarily during our
early stage of development, our procedures with respect to the manner of
granting options to new employees were not clearly documented. As a result of
these factors, and in light of the receipt of the above claims, we have in the
past received, and may in the future receive, similar claims from one or more
individuals asserting rights to acquire shares of our stock or to receive cash
compensation. We cannot predict whether such future claims will be made or the
ultimate resolution of any currently outstanding or future claim. See
"InfoSpace Business--Legal Proceedings."

We may require additional funding.

  Although we believe that our cash reserves and cash flows from operations
will be adequate to fund our operations for at least the next 12 months, such
sources may be inadequate. Consequently, we may require additional funds during
or after such period. Additional financing may not be available on favorable
terms or at all. If we raise additional funds by selling stock, the percentage
ownership of our then current stockholders will be reduced. If we cannot raise
adequate funds to satisfy our capital requirements, we may

                                       23
<PAGE>

have to limit our operations significantly. Our future capital requirements
depend upon many factors, including, but not limited to:

  . the rate at which we expand our sales and marketing operations;

  . the amount and timing of fees paid to affiliates to include our consumer,
    merchant and wireless services on their site or service;

  . the extent to which we expand our consumer, merchant and wireless
    services;

  . the extent to which we develop and upgrade our technology and data
    network infrastructure;

  . the occurrence, timing, size and success of acquisitions;

  . the cash requirements of entities we have acquired;

  . the number and amount of investments we make in privately held technology
    companies;

  . the rate at which we expand internationally; and

  . the response of competitors to our service offerings.

  See "InfoSpace Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."

Management owns a large percentage of our stock.

  As of July 31, 2000, our officers, directors and affiliated persons
beneficially owned approximately 32% of our common stock. Naveen Jain, our
Chairman, beneficially owned approximately 22% of our common stock as of that
date. As a result, our officers, directors and affiliated persons may
effectively be able to:

  . elect, or defeat the election of, our directors;

  . amend or prevent amendment of our Certificate of Incorporation or Bylaws;

  . effect or prevent a merger, sale of assets or other corporate
    transaction; and

  . control the outcome of any other matter submitted to the stockholders for
    vote.

  Our public stockholders may have little control over the outcome of such
transactions. Management's stock ownership may discourage a potential acquirer
from making a tender offer or otherwise attempting to obtain control of
InfoSpace, which in turn could reduce our stock price or prevent our
stockholders from realizing a premium over our stock price.

Risks Relating to Go2Net

  Go2Net operates in a rapidly changing environment that involves a number of
risks, some of which are beyond Go2Net's control. The following discussion
highlights some of these risks. These risks should be read in conjunction with
the "Factors Affecting Go2Net's Business, Operating Results and Financing
Condition" section included in Go2Net's Form 10-K for the fiscal year ended
September 30, 1999.

Go2Net's arrangements with advertisers and sponsors may expose it to
significant financial risks.

  Go2Net enters into advertising arrangements with third parties to provide
services on its Web sites, which involve a unique rate structure. Specifically,
Go2Net receives sponsorship fees and, under certain circumstances, a portion of
transaction revenues received by third party sponsors from users originated
through its Web sites, in return for minimum levels of user impressions or user
requests for additional information made by clicking on the promotional
hyperlink or advertisement. To the extent implemented, these arrangements
expose Go2Net to potentially significant financial risks, including the risk
that Go2Net

                                       24
<PAGE>

fails to deliver required minimum levels of user impressions (in which case,
these agreements typically provide for adjustments to the fees payable
thereunder or "make good" periods) and that third party sponsors do not renew
the agreements at the end of their terms. Some of these arrangements also
require Go2Net to integrate advertisers' or sponsors' content with its
services, which requires the dedication of resources and significant
programming and design efforts to accomplish. Go2Net cannot assure you that it
will be able to attract additional advertisers or sponsors or that it will be
able to renew existing advertising arrangements when they expire. In addition,
Go2Net has granted exclusivity provisions to some of its sponsors and may in
the future grant additional exclusivity provisions. These exclusivity
provisions may have the effect of preventing Go2Net, for the duration of the
exclusivity arrangements, from accepting advertising or sponsorship
arrangements within a particular subject matter in its Web sites or across its
entire service. Go2Net's inability to enter into further sponsorships or
advertising arrangements as a result of its exclusivity arrangements could have
a material adverse impact its business, financial condition and operating
results.

Risks relating to Go2Net's broadband services

  Go2Net's broadband business is unproven, and it may not achieve
profitability.

  Go2Net's broadband business is unproven, and it may not achieve widespread
consumer or commercial acceptance. Go2Net has had difficulty predicting whether
the pricing models or revenue sharing arrangements with its cable and other
high speed access providers for its broadband services will prove to be viable,
the level of demand for its broadband services at the prices these broadband
partners are anticipated to charge for its broadband services or whether
pricing levels will be sustainable. If these pricing levels are not achieved or
sustained or if its broadband services do not achieve or sustain broad market
acceptance, its business will be significantly harmed.

  Growth of Go2Net's broadband service may be inhibited by factors beyond its
control.

  Go2Net's ability to increase the number of subscribers to its broadband
service to achieve its business plans and generate future revenues will depend
on many factors which are beyond its control. For instance, some of Go2Net's
cable and other high speed access providers have not achieved the subscriber
levels that they had originally anticipated. Other factors include:

  . the rate at which Go2Net's current and future broadband partners upgrade
    their broadband infrastructures for two-way data services and the
    commercial availability of hardware and software necessary for these
    services;

  . Go2Net's ability and the ability of its broadband partners to coordinate
    timely and effective marketing campaigns with the availability of
    broadband infrastructure upgrades;

  . the success of its broadband partners in marketing and installing
    broadband service in their local service areas;

  . the prices that Go2Net's broadband partners set for broadband service and
    for its installation;

  . the speed at which Go2Net's broadband partners can complete the
    installations required to initiate service for new subscribers;

  . the commercial availability of self-installable, two-way modems that
    comply with the recently adopted interface standards known as DOCSIS, and
    the success of the roll-out of these products with broadband services;
    and

  . the quality of customer and technical support Go2Net's broadband partners
    provide.

                                       25
<PAGE>


  If Go2Net does not develop new and enhanced features, products and services
  for its broadband services, Go2Net may not be able to attract and retain a
  sufficient number of users.

  Because of the competitiveness of the broadband market, Go2Net believes it is
important to introduce additional or enhanced features, products and services
in the future in order to differentiate its services and attract users. If
Go2Net introduces a feature, product or service that is not favorably received,
people will not use its service, and they may choose a competing service.

  Go2Net will need to continually enhance its products and services to
incorporate rapidly changing technologies. Go2Net could incur substantial
development costs if Go2Net needs to modify its products, services or
infrastructure to adapt. Go2Net's business could be harmed if Go2Net incurs
significant costs to adapt to these changes. If Go2Net cannot adapt to these
changes, users may discontinue using its services.

  Go2Net may also experience difficulties that could delay or prevent it from
introducing its broadband features, products or services. Furthermore, these
features, products or services may contain errors that are discovered after the
feature, product or services are introduced. Go2Net may need to modify the
design of them significantly to correct these errors. In addition, Go2Net must
consult with and involve its principal cable partners in the development and
design of new features, products or services for its broadband services.
Therefore, the process of introducing new broadband features, products and
services is time consuming and if Go2Net's principal cable partners object to a
new feature, product or service, Go2Net could be prohibited from offering it in
particular areas. Go2Net's business could be adversely affected if Go2Net
experiences difficulties in introducing new products and services or if users
do not accept these new products or services.

Go2Net depends on continued growth in electronic commerce and Internet
infrastructure development.

  Use of the Internet by businesses and consumers as a medium for electronic
commerce is at an early stage of development and is subject to a level of
uncertainty. Go2Net depends on the growing use and acceptance of the Internet
as an effective medium of commerce by merchants and customers. The use of and
interest in the Internet is a relatively recent development. Go2Net cannot be
certain that acceptance and use of the Internet will continue to develop as a
medium for commerce or that a sufficiently broad base of merchants and
consumers will adopt, and continue to use, the Internet as a medium of
commerce.

  The emergence of the Internet as a commercial marketplace may occur more
slowly than anticipated for a number of reasons, including potentially
inadequate development of the necessary network infrastructure or delayed
development of enabling technologies and performance improvements. If the
number of Internet users or their use of Internet resources continues to grow,
it may overwhelm the existing Internet infrastructure. Delays in the
development or adoption of new standards and protocols required to handle
increased levels of Internet activity could also have a detrimental effect.
These factors could result in slower response times or adversely affect usage
of the Internet, resulting in lower numbers ecommerce transactions and lower
demand for Go2Net's services.

  Go2Net's success also depends on its ability to grow, or scale, its ecommerce
transaction systems to accommodate increases in the volume of traffic on its
systems, especially during peak periods of demand. Go2Net may not be able to
anticipate increases in the use of its systems and successfully expand the
capacity of its network infrastructure. Go2Net's inability to expand its
systems to handle increased traffic could result in system disruptions, slower
response times and other difficulties in providing services to its merchant
customers, which could materially harm its business.

                                       26
<PAGE>

Go2Net is exposed to electronic commerce security risks.

  A requirement of the continued growth of e-commerce is the secure
transmission of confidential information over public networks. Go2Net relies on
public key cryptography and digital certificate technology to provide the
security and authentication necessary for secure transmission of confidential
information. Various regulatory and export restrictions may prohibit Go2Net
from using the strongest and most secure cryptographic protection available and
thereby expose Go2Net to a risk of data interception. A party who is able to
circumvent Go2Net's security measures could misappropriate proprietary
information or interrupt its operations. Any such compromise or elimination of
Go2Net's security could reduce demand for its services.

The market for Go2Net's products and services has a low barrier of entry.

  The market for Internet-based products and services is relatively new,
intensely competitive and rapidly evolving. There are minimal barriers to
entry, and current and new competitors can launch new Internet sites at a
relatively low cost within relatively short time periods. In addition, Go2Net
competes for the time and attention of Internet users with thousands of non-
profit Internet sites operated by individuals, government and educational
institutions. Existing and potential competitors also include magazine and
newspaper publishers, cable television companies and start-up ventures
attracted to the Internet market. As a result, Go2Net expects competition to
persist and intensify and the number of competitors to increase significantly
in the future. As Go2Net attempts to expand the scope of its Internet sites and
product offerings, Go2Net will compete with a greater number of Internet sites
and other companies. Because the operations and strategic plans of existing and
future competitors are undergoing rapid change, it is extremely difficult for
Go2Net to anticipate which companies are likely to offer competitive products
and services in the future. There can be no assurance that Go2Net's Internet
sites will compete successfully.

Go2Net's success depends on its ability to maintain advertising, licensing and
electronic commerce revenues.

  Go2Net derives a significant portion of its revenues from the sale of
advertising on its Internet sites. Go2Net will not be able to maintain or
increase its advertising revenues in the future if its advertising customers
move their advertising to competing Internet sites or to traditional forms of
media. Additionally, in selling Internet-based advertising, Go2Net depends in
part on advertising agencies, which exercise substantial control over the
placement of advertising for their clients. Go2Net derives a significant
portion of its revenues from licensing and electronic commerce. Go2Net depends
on its ability to continue to license its technology and applications to third
parties. Additionally, Go2Net must increase the number of merchants that use
its payment process platform and increase the volume of transactions that it
processes. Go2Net's success will depend on its ability to retain, broaden and
diversify its future base of advertising, licensing and electronic commerce
customers.

Alliances may make it more difficult to access Go2Net's products and media
properties.

  The acquisitions and alliances among Go2Net's competitors will result in
greater competition as more users of the Internet consolidate on fewer services
that incorporate search and retrieval features. In addition, providers of
software and other Internet products and services are incorporating search and
retrieval features into their offerings. For example, Web browsers offered by
Netscape and Microsoft increasingly incorporate prominent search buttons that
direct search traffic to competing services. These features could make it more
difficult for Internet users to find and use Go2Net's products and services. In
the future, Netscape, Microsoft and other browser suppliers may also more
tightly integrate products and services similar to Go2Net into their browsers
or their browsers' pre-set home pages. Any of these companies could take
actions that would make it more difficult for consumers to find and use
Go2Net's services. Microsoft signed a long term partnership with LookSmart to
provide directory services in the Microsoft Network and other Microsoft online
properties. These search services may be tightly integrated into future
versions of the Microsoft operating system, the

                                       27
<PAGE>

Internet Explorer browser, and other software applications, and Microsoft may
promote these services within the Microsoft Network or through other Microsoft
affiliated end-user services such as MSNBC or WebTV Networks. Each of these
situations creates a potential competitive advantage over Go2Net because their
Internet navigational offerings may be more conveniently accessed by users.

Go2Net's competitors have greater resources than Go2Net does.

  Many, if not all, of Go2Net's competitors have significantly greater
resources than Go2Net does. In particular, Go2Net's competitors have greater
financial, editorial, technical and marketing resources, longer operating
histories, greater name recognition, and greater experience than Go2Net does.
Additionally, Go2Net's competitors have established relationships with more
advertisers and advertising agencies. And they are able to undertake more
extensive marketing campaigns, adopt more aggressive advertising and
subscription price policies and devote substantially more resources to
developing Internet-based products and services than Go2Net is. There can be no
assurance that Go2Net will be able to compete successfully against current or
future competitors or that competitive pressures faced by Go2Net will not
materially adversely affect Go2Net's business, financial condition and
operating results.

Increased competition may exert downward pricing pressure on advertising
contracts.

  Go2Net competes with online services, other Web site operators and
advertising networks, as well as traditional offline media such as television,
radio and print for a share of advertisers' total advertising budgets. Go2Net
believes that the number of companies selling Web-based advertising and the
available inventory of advertising space has recently increased substantially.
Accordingly, Go2Net may face increased pricing pressure for the sale of
advertisements, which could reduce its advertising revenues. In addition,
Go2Net's sales may be adversely affected to the extent that its competitors
offer superior advertising services that better target users or provide better
reporting of advertising results.

Go2Net must develop and maintain a "brand identity" for its products.

  Go2Net believes that maintaining and building the Go2Net brand is a critical
aspect of its efforts to attract an Internet audience. In addition, Go2Net
believes that the importance of brand recognition will increase due to the
anticipated increase in the number of Internet sites and the relatively low
barriers to entry to providing Internet-based products and services. Promoting
the Go2Net brand name will depend on Go2Net's continued ability to develop and
deliver original and compelling Internet-based products and services. If
Internet users do not continue to perceive Go2Net's Internet sites to be of
sufficient interest and usefulness, Go2Net will be unsuccessful in promoting
and maintaining its brand. If Go2Net expands the focus of its operations beyond
providing its current Internet sites, Go2Net risks diluting its brand,
confusing users and advertisers, and decreasing the attractiveness of its
audience to advertisers. In order to respond to competitive pressures, Go2Net
may find it necessary to increase its budget for developing its products and
services or otherwise to increase substantially its financial commitment to
creating and maintaining a distinct brand loyalty among users. If Go2Net is
unable to provide internet-based products and services or otherwise fails to
promote and maintain the Go2Net brand, or if Go2Net incurs significant expenses
in an attempt to improve its products and services or promote and maintain its
brand, its business, financial condition and operating results will be
adversely affected.

The Internet is characterized by rapid technological changes, and Go2Net must
adapt quickly to these changes to compete effectively.

  The market for Internet products and services is characterized by rapid
technological developments, evolving industry standards and customer demands,
and frequent new product introductions and enhancements. For example, to the
extent that higher bandwidth Internet access becomes more widely available,
Go2Net may be required to make significant changes to the design and content of
its products and

                                       28
<PAGE>

media properties. Failure to effectively adapt to these or any other
technological developments could adversely affect Go2Net's business, operating
results and financial condition.

Go2Net may have difficulty managing its growth and integrating recently
acquired companies.

  Go2Net's recent growth has placed a significant strain on its managerial,
operational, and financial resources. To manage its growth, Go2Net must
continue to implement and improve its operational and financial systems and to
expand, train, and manage its employee base. Any inability to manage growth
effectively could have a material adverse effect on Go2Net's business,
operating results, and financial condition.

Go2Net depends upon third parties for critical elements of its business.

  Go2Net depends upon third parties in order to advertise its Internet sites on
other Internet sites. In addition, the willingness of the owners and operators
of these sites to direct users to Go2Net's Internet sites through hypertext
links are critical to the success of its Internet operations. There can be no
assurance that Go2Net will establish or maintain such arrangements in the
future.

Go2Net depends on third parties for content development of its Internet sites.

  Go2Net's ability to develop original and compelling Internet-based products
and services is also dependent on maintaining relationships with and using
products provided by third-party vendors. Developing and maintaining
satisfactory relationships with third parties could become more difficult and
more expensive as competition increases among Internet sites. If Go2Net is
unable to develop and maintain satisfactory relationships with third parties on
terms acceptable to Go2Net, or if Go2Net's competitors are better able to
leverage these relationships, its business, financial condition and operating
results will be materially adversely affected. Go2Net has relied, and will
continue to rely substantially, on the product and service development efforts
of third parties. For example, Go2Net relies on S&P Comstock, Dow Jones &
Company, Inc., New York Stock Exchange, Inc., The Nasdaq Stock Market, Inc.,
Reuters and Market Guide, Inc. to provide a significant portion of the
information included on Go2Net's Internet sites. There can be no assurance
Go2Net will maintain its relationships in the future. Any failure of third
parties to provide this information to Go2Net could have a material adverse
effect on its business, financial condition and operating results.

Go2Net's performance depends on the success of the Metacrawler license.

  Go2Net entered into a License Agreement with Netbot, Inc. (the "MetaCrawler
License Agreement"), in which Netbot, Inc. granted Go2Net an exclusive (subject
to some limited exceptions), worldwide license to provide the MetaCrawler
Service. As part of the MetaCrawler License Agreement, Go2Net has the exclusive
right to operate, modify and reproduce the MetaCrawler Service (including,
without limitation, the exclusive right to use, modify and reproduce the name
"MetaCrawler" and the MetaCrawler URL in connection with the operation of the
MetaCrawler Service). A material portion of the traffic to Go2Net's Internet
sites is currently derived from users of the MetaCrawler Service. A termination
of the MetaCrawler License Agreement or the inability of Go2Net to continue to
provide access to the search engines included in the MetaCrawler Service, could
have a material adverse effect on Go2Net's business, financial condition and
operating results. Netbot has licensed the MetaCrawler Service and the other
intellectual property rights associated therewith from the University of
Washington on an exclusive basis. The license has been granted to Go2Net by
Netbot on an exclusive basis, but Netbot has reserved the right to use, modify,
reproduce and license the MetaCrawler search engine for any purpose other than
the provision of the MetaCrawler Service. The license is subject to the rights
of the University of Washington to use, modify and reproduce the MetaCrawler
search engine and derivatives of the MetaCrawler site to operate Internet sites
for internal purposes within the University of Washington domain and to use,
modify and reproduce any of the licensed

                                       29
<PAGE>

technologies for research, instructional and academic purposes. The search
technology underlying the MetaCrawler Service and the MetaCrawler trademark is
licensed to or owned by Netbot and sublicensed to Go2Net pursuant to the
MetaCrawler License Agreement.

Go2Net is subject to U.S. and foreign government regulation of the Internet,
the impact of which is difficult to predict.

  There are currently few laws or regulations directly applicable to the
Internet. The application of existing laws and regulations to Go2Net relating
to issues such as user privacy, defamation, pricing, advertising, taxation,
gambling, sweepstakes, promotions, content regulation, quality of products and
services, and intellectual property ownership and infringement can be unclear.
In addition, Go2Net will also be subject to new laws and regulations directly
applicable to its activities. Any existing or new legislation applicable to
Go2Net could expose Go2Net to substantial liability, including significant
expenses necessary to comply with these laws and regulations, and dampen the
growth in use of the Web.

  Other nations, including Germany, have taken actions to restrict the free
flow of material deemed to be objectionable on the Web. The European Union has
recently adopted privacy and copyright directives that may impose additional
burdens and costs on Go2Net's international operations. In addition, several
telecommunications carriers, including America's Carriers' Telecommunications
Association, are seeking to have telecommunications over the Web regulated by
the FCC in the same manner as other telecommunications services. Many areas
with high Web use have begun to experience interruptions in phone service, and
local telephone carriers, such as Pacific Bell, have petitioned the FCC to
regulate ISPs and OSPs and to impose access fees. A number of proposals have
been made at the federal, state and local level that would impose additional
taxes on the sale of goods and services through the Internet. If any such
proposals are adopted, it could substantially impair the growth of the Internet
and adversely affect Go2Net.

  Several recently passed federal laws could have an impact on Go2Net's
business. The Digital Millennium Copyright Act is intended to reduce the
liability of online service providers for listing or linking to third-party Web
sites that include materials that infringe copyrights or other rights of
others. The Children's Online Protection Act and the Children's Online Privacy
Protection Act are intended to restrict the distribution of materials deemed
harmful to children and impose additional restrictions on the ability of online
services to collect user information from minors. In addition, the Protection
of Children From Sexual Predators Act of 1998 requires online service providers
to report evidence of violations of federal child pornography laws under some
circumstances. Such legislation may impose significant additional costs on
Go2Net's business or subject Go2Net to additional liabilities.

  Due to the global nature of the Web, it is possible that the governments of
other states and foreign countries might attempt to regulate its transmissions
or prosecute Go2Net for violations of their laws. Go2Net might unintentionally
violate these laws. These laws may be modified, or new laws enacted, in the
future. Any such developments could have a material adverse effect on Go2Net's
business, results of operations, and financial condition.

Go2Net may be subject to a variety of legal uncertainties that impair its
business.

  As a publisher and a distributor of content over the Internet, Go2Net faces
potential liability for defamation, negligence, copyright, patent or trademark
infringement and other claims based on the nature and content of the materials
that Go2Net publishes or distributes. In addition, Go2Net could be exposed to
liability with respect to the content or unauthorized duplication of material
indexed in its search services. Although Go2Net carries liability insurance,
its insurance may not cover potential claims of this type or may not be
adequate to indemnify Go2Net for all liability that may be imposed.

  Go2Net hosts a wide variety of services that enable individuals to exchange
information, generate content, conduct business and engage in various online
activities, including services relating to online

                                       30
<PAGE>

auctions and the homesteading and other services. The law relating to the
liability of providers of these online services for activities of their users
is currently unsettled. Claims could be made against Go2Net for defamation,
negligence, copyright or trademark infringement, unlawful activity, tort,
including personal injury, fraud or other theories based on the nature and
content of information that Go2Net provides links to or that may be posted
online or generated by its users or with respect to auctioned materials. These
types of claims have been brought, and sometimes successfully prosecuted,
against online service providers in the past. In addition, Go2Net is aware that
governmental agencies are currently investigating the conduct of online
auctions.

  Go2Net also periodically enters into arrangements to offer third-party
products, services, or content under the Go2Net brand or via distribution on
Go2Net's properties, including stock quotes and trading information. Go2Net may
be subject to claims concerning these products, services or content by virtue
of its involvement in marketing, branding, broadcasting or providing access to
them, even if Go2Net does not itself host, operate, provide, or provide access
to these products, services or content. While Go2Net's agreements with these
parties often provide that Go2Net will be indemnified against such liabilities,
such indemnification may not be adequate.

  It is also possible that, if any information provided directly by Go2Net
contains errors or is otherwise negligently provided to users, third parties
could make claims against it. For example, Go2Net offers Web-based email
services, which expose Go2Net to potential risks, such as liabilities or claims
resulting from unsolicited email, lost or misdirected messages, illegal or
fraudulent use of email, or interruptions or delays in email service.

Go2Net is subject to pending legal proceedings.

  From time to time, Go2Net is, and expects to continue to be, subject to legal
proceedings and claims in the ordinary course of its business, including claims
of alleged infringement of third-party trademarks and other intellectual
property rights by Go2Net. These claims, even if not meritorious, could require
the expenditure of significant financial and managerial resources which could
harm Go2Net's business.

  Authorize.Net Corporation, a subsidiary of Go2Net, has been named as a
defendant in a suit filed in June 2000 which purports to be a class action
brought on behalf of persons who leased "virtual terminals" from Authorize.Net
among a myriad of other non-Authorize.Net products in connection with actual or
proposed internet businesses. The leases were allegedly financed by a third-
party unaffiliated leasing company in connection with sales efforts by a third-
party unaffiliated reseller. The suit, insofar as it relates to Authorize.Net,
alleges that the leases of the products at issue were actually sales and that
they were financed by the leasing company at usurious rates. The suit further
alleges that the reseller was acting as an agent of Authorize.Net in these
activities. Go2Net believes that Authorize.Net has meritorious defenses to this
claim against it. Nevertheless, litigation is inherently uncertain, and
Authorize.Net may not prevail in this suit.

Go2Net's success depends on its ability to protect its proprietary technology.

  Go2Net's success is dependent upon its ability to protect and leverage the
value of its original Internet technologies, software, content and its
trademarks, trade names, service marks, domain names and other proprietary
rights Go2Net either currently has or may have in the future. Go2Net has filed
service marks for its logo and name, as well as for the names of each of its
sites. In addition, given the uncertain application of existing copyright and
trademark laws to the Internet, there can be no assurance that existing laws
will provide adequate protection for Go2Net's technologies, sites or domain
names. Policing unauthorized use of Go2Net's technologies, content and other
intellectual property rights entails significant expenses and could otherwise
be difficult or impossible to do given the global nature of the Internet.
Actions of other parties in enforcing their intellectual property rights could
prohibit us from offering new products that are complementary to our business
model.

                           COMPARATIVE PER SHARE DATA

  The following table reflects (a) the historical net loss and book value per
share of InfoSpace common stock and the historical net loss and book value per
share of Go2Net common stock in comparison with the unaudited pro forma net
loss and book value per share after giving effect to the proposed merger of a
wholly-owned subsidiary of InfoSpace with and into Go2Net, and (b) the
equivalent historical net loss and book value per share attributable to 1.82
shares of InfoSpace common stock which will be received for each share of
Go2Net common stock.

  The historical book value per share is computed by dividing stockholders'
equity, by the actual common stock outstanding. The pro forma per share net
loss from continuing operations is computed by dividing the pro forma net loss
from continuing operations by the pro forma weighted average number of shares
outstanding, assuming InfoSpace had merged with Go2Net at the beginning of the
earliest period presented and Go2Net shares were converted to InfoSpace shares
at an exchange ratio of 1.82. The pro forma combined book value per share is
computed by dividing total pro forma stockholders' equity by the pro forma
number of common shares outstanding, assuming the merger (and conversion of
shares) had occurred on that date.

  The following information should be read in conjunction with the separate
audited historical consolidated financial statements and related notes of
InfoSpace and Go2Net, the unaudited pro forma condensed combined financial
information and related notes of InfoSpace and the selected historical and
selected unaudited pro forma financial data included elsewhere in this joint
proxy statement/prospectus. 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 merger of
InfoSpace and Go2Net 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 company.

  Go2Net stockholders are advised to obtain current market quotations for
InfoSpace common stock and Go2Net common stock. No assurance can be given as to
the market prices of InfoSpace common stock or Go2Net common stock at any time
before the consummation of the merger or as to the market price of InfoSpace
common stock at any time after the merger. Because the exchange ratio is fixed,
the exchange

                                       36
<PAGE>

ratio will not be adjusted to compensate Go2Net stockholders for decreases in
the market price of InfoSpace common stock which have and could occur before
the merger becomes effective. In the event the market price of InfoSpace common
stock decreases or increases prior to the consummation of the merger, the value
of the InfoSpace common stock to be received in the merger in exchange for
Go2Net common stock would correspondingly decrease or increase.

Dividends

  Neither InfoSpace nor Go2Net has ever declared or paid cash dividends on its
capital stock. Pursuant to the merger agreement, each of InfoSpace and Go2Net
has agreed not to pay cash dividends pending the consummation of the merger,
without the written consent of the other. If the merger is not consummated, the
Go2Net board anticipates that it would continue its policy of retaining any and
all earnings to finance the expansion of its business. InfoSpace expects to
retain any and all earnings for use in the operation and expansion of its
business and does not anticipate paying any cash dividends before or after the
merger.

                             9:00 a.m. Pacific Time

                             100 112th Avenue

                        Bellevue, Washington 98004

Purpose of the special meeting

  InfoSpace is furnishing this joint proxy statement/prospectus to its
stockholders in connection with the solicitation of proxies by InfoSpace's
board of directors. The InfoSpace board of directors will use the proxies at
the special meeting of stockholders of InfoSpace to be held on October 12, 2000
and at any adjournment or postponement thereof.

  The special meeting is being held so that InfoSpace stockholders may consider
and vote upon the following proposals:

  1. To approve the issuance of shares of InfoSpace common stock in the
     proposed merger of a wholly-owned subsidiary of InfoSpace with and into
     Go2Net, Inc., as contemplated by the Agreement and Plan of
     Reorganization dated as of July 26, 2000, by and among InfoSpace, Go2Net
     and a wholly-owned subsidiary of InfoSpace. InfoSpace will issue 1.82
     shares of common stock in exchange for each share of outstanding common
     stock of Go2Net and Go2Net will become a wholly-owned subsidiary of
     InfoSpace.

  2. To transact any other business that properly comes before the special
     meeting or any adjournments or postponements thereof.

Record date and outstanding shares

  InfoSpace's board of directors has fixed the close of business on August 28,
2000 as the record date for the special meeting. Only holders of record of
InfoSpace's common stock at the close of business on the record date are
entitled to notice of and to vote at the meeting. As of August 28, there were
233,598,517 shares of common stock outstanding and entitled to vote. These
shares were held of record by approximately 813 stockholders, although
InfoSpace has been informed that there are in excess of 190,000 beneficial
owners of its common stock.

Vote and quorum required

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

  As of July 31, 2000, directors, executive officers and affiliates of
InfoSpace as a group beneficially owned 107,224,105 shares of common stock,
which represents approximately 45.9% of the total voting power represented by
InfoSpace's outstanding common stock. Three affiliated stockholders of
InfoSpace have entered into voting agreements with Go2Net that obligates them
to vote all of their shares, a total of approximately 24.1% of the total voting
power represented by InfoSpace's common stock outstanding as of July 26, 2000,
in favor of approval of the issuance of common stock in connection with the
merger.

                                       38
<PAGE>

Abstentions; broker non-votes

  Any abstention will be counted for purposes of determining a quorum, and will
have no effect on the outcome of the proposal to approve the issuance of
InfoSpace common stock in the merger.

  In the event that a broker, bank, custodian, nominee or other record holder
of InfoSpace's common stock indicates on a proxy that it does not have
discretionary authority to vote certain shares on a particular matter, which is
called a "broker non-vote," those shares will not be considered for purposes of
determining the number of shares entitled to vote with respect to a particular
proposal on which the broker has expressly not voted, but will be counted for
purposes of determining the presence or absence of a quorum for the transaction
of business.

Expenses of proxy solicitation

  InfoSpace will pay the expenses of soliciting proxies to be voted at the
meeting, except that Go2Net will share equally the expenses incurred in
connection with filing and printing this joint proxy statement/prospectus.
Following the original mailing of the proxies and other soliciting materials,
InfoSpace will request brokers, custodians, nominees and other record holders
of InfoSpace common stock to forward copies of the proxy and other soliciting
materials to persons for whom they hold shares of InfoSpace common stock and to
request authority for the exercise of proxies. In such cases, upon the request
of the record holders, InfoSpace will reimburse such holders for their
reasonable expenses.

  InfoSpace has retained D.F. King & Co., Inc. to aid in the solicitation of
proxies and to verify records relating to the solicitations. D.F. King will
receive $9,000 and customary expense reimbursement for these services. In
addition to solicitation by mail, directors, officers and key employees of
InfoSpace may solicit proxies in person or by telephone, telegram or other
means of communication. These persons will receive no additional compensation
for solicitation of proxies but may be reimbursed for reasonable out-of-pocket
expenses.

Voting of proxies

  The proxy accompanying this joint proxy statement/prospectus is solicited on
behalf of the InfoSpace board of directors for use at the meeting. Please
complete, date and sign the accompanying proxy and promptly return it in the
enclosed envelope or otherwise mail it to InfoSpace. All properly signed
proxies that InfoSpace receives prior to the vote at the meeting and that are
not revoked will be voted at the meeting according to the instructions
indicated on the proxies or, if no direction is indicated, such proxies will be
voted FOR each of the proposals to be considered at the special meeting. You
may revoke your proxy at any time before it is exercised at the meeting by
taking any of the following actions:

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

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

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

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

your proxy card.

Recommendation of the board of directors

  The board of directors of InfoSpace has unanimously determined that the terms
of the merger agreement and the issuance of common stock in the merger are in
the best interests of InfoSpace and the InfoSpace stockholders. Accordingly,
the InfoSpace board of directors unanimously recommends that InfoSpace
stockholders vote FOR the proposal to approve the issuance of common stock in
the merger.

     and into Go2Net, Inc. and to adopt the merger agreement among InfoSpace,
     Inc., Giants Acquisition Corp., a wholly owned subsidiary of InfoSpace,
     Inc., and Go2Net, Inc., under which each outstanding share of Go2Net
     common stock will be converted into the right to receive 1.82 shares of
     InfoSpace common stock; and

  2. To transact such other business as may properly come before the special
     meeting or any adjournment or postponement thereof.

Record date and outstanding shares

  The Go2Net board of directors has fixed the close of business on August 28,
2000 as the record date for the special meeting. Only holders of record of
Go2Net common stock and series A preferred stock on the record date are
entitled to notice of and to vote at the special meeting. As of August 28,
2000, Go2Net had outstanding and entitled to vote 40,464,956 shares of common
stock (including shares of series A preferred stock on an as converted basis),
held of record by approximately 318 stockholders although Go2Net has been
informed that there are in excess of 52,000 beneficial owners of common stock.
At the close of business on this date, Go2Net had outstanding and entitled to
vote 300,000 shares of preferred stock held of record by one stockholder.

Vote and quorum required

  Holders of Go2Net common stock are entitled to one vote for each share held
as of the record date. Each record holder of preferred stock will be entitled
to one vote for each share of common stock into which the holder's preferred
stock may be converted. Approval of the merger and adoption of the merger
agreement will require the affirmative vote of a majority of the outstanding
shares of Go2Net common stock (including shares of Go2Net common stock issuable
upon conversion of shares of Go2Net preferred stock) as well as a majority of
the outstanding shares of Go2Net preferred stock voting as a separate class.
Attendance at the meeting in person or by proxy of the shares representing a
majority of the shares of Go2Net common stock (including shares of Go2Net
common stock issuable upon conversion of share of Go2Net preferred stock)
issued and outstanding on the record date is required for a quorum.

  On August 28, 2000, directors and executive officers of Go2Net and their
affiliates beneficially owned, and were entitled to vote, 18,011,984 shares of
Go2Net common stock (including shares of Go2Net common stock issuable upon
conversion of shares of Go2Net preferred stock), or approximately 44.5% of the

                                       41
<PAGE>


outstanding voting shares. Four affiliated stockholders of Go2Net who as of
July 26, 2000 together owned a total of approximately 36.8% of the voting power
of Go2Net capital stock (including shares of common stock issuable upon
conversion of shares of Go2Net preferred stock), have entered into voting
agreements and have agreed to vote in favor of the adoption of the merger
agreement. In order to receive the required number of votes to approve the
merger and adopt the merger agreement, holders of approximately 21% of the
Go2Net common stock who are not party to the voting agreements must vote their
shares in favor of the approval of the merger and adoption of the merger
agreement.

Abstentions and broker non-votes

  Abstentions and broker non-votes each will be included in determining the
number of shares present and voting at the meeting for the purpose of
determining the presence of a quorum. Because approval of the merger and
adoption of the merger agreement requires the affirmative vote of a majority of
the outstanding shares of Go2Net common stock (including shares of common stock
issuable upon conversion of shares of Go2Net preferred stock) entitled to vote
and of a majority of the outstanding shares of Go2Net preferred stock entitled
to vote, abstentions and broker non-votes will have the same effect as votes
against the approval of the merger and adoption of the merger agreement. In
addition, the failure of a Go2Net stockholder to return a proxy or vote in
person will have the effect of a vote against the approval of the merger and
adoption of the merger agreement. Brokers holding shares for beneficial owners
cannot vote on the actions proposed in this joint proxy statement/prospectus
without the owners' specific instructions. Accordingly, Go2Net stockholders are
urged to return the enclosed proxy card marked to indicate their vote.

Expenses of proxy solicitation

  Go2Net will pay the costs of soliciting proxies to be voted at the Go2Net
special meeting, except that InfoSpace will share equally the expenses incurred
in connection with filing and printing this joint proxy statement/prospectus.
Following the original mailing of the proxies and other soliciting materials,
Go2Net will request brokers, custodians, nominees and other record holders of
Go2Net stock to forward copies of the proxy and other soliciting materials to
persons for whom they hold shares of Go2Net stock and to request authority for
the exercise of proxies. In such cases, upon the request of the record holders,
Go2Net will reimburse such holders for their reasonable expenses.

  Go2Net retained D.F. King & Co. Inc. to aid in the solicitation of proxies
and to verify records relating to the solicitations. D.F. King will receive
$6,500 and customary expense reimbursement for these services. In addition to
solicitation by mail, directors, officers and key employees of Go2Net may
solicit proxies in person or by telephone, telegram or other means of
communication. These persons will receive no additional compensation for
solicitation of proxies but may be reimbursed for reasonable out-of-pocket
expenses.

Voting of proxies

  The proxy accompanying this joint proxy statement/prospectus is solicited on
behalf of the Go2Net board of directors for use at the special meeting. Please
complete, date and sign the accompanying proxy and promptly return it in the
enclosed envelope or otherwise mail it to Go2Net. All properly signed proxies
that Go2Net receives prior to the vote at the meeting and that are not revoked
will be voted at the meeting according to the instructions indicated on the
proxies or, if no direction is indicated, such proxies will be voted FOR each
of the proposals to be considered at the special meeting. Brokers will provide
directions on how to instruct the broker to vote the shares to the beneficial
owners of such shares. You may revoke your proxy at any time before it is
exercised at the meeting by taking any of the following actions:

  . delivering a written notice to the secretary of Go2Net by any means,
    including facsimile, bearing a date later than the date of the proxy,
    stating that the proxy is revoked;

                                       42
<PAGE>

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

  Go2Net's board of directors does not know of any matter that is not referred
to in this joint proxy statement/prospectus to be presented for action at the
meeting. If any other matters are properly brought before the meeting, the
persons named in the proxies will have discretion to vote on such matters in
accordance with their best judgment.

Recommendations

  The Go2Net board has determined that the merger and the reorganization
agreement are advisable and fair to and in the best interests of Go2Net and its
stockholders. Accordingly after careful consideration, the Go2Net board
unanimously has approved the merger and the merger agreement and unanimously
recommends that the stockholders vote for the approval of the merger and the
adoption of the merger agreement.

  Do not send in any stock certificates with your proxy. The exchange agent
will mail transmittal forms with instructions for the surrender of stock
certificates for Go2Net shares to former Go2Net stockholders as soon as
practicable after the completion of the merger.


   To assure that your shares are represented at the meeting, please
 complete, date and sign the enclosed proxy and mail it promptly in the
 postage-paid envelope provided, whether or not you plan to attend the
 meeting. You may revoke your proxy at any time before it is voted.

                                   THE MERGER

  This section of the joint proxy statement/prospectus describes the proposed
merger. While InfoSpace and Go2Net believe that the description covers the
material terms of the merger and the related transactions, this summary may not
contain all of the information that is important to you. You should carefully
read this entire document and the other documents InfoSpace and Go2Net referred
to for a more complete understanding of the merger.

Background of the merger

  Naveen Jain, Chairman of InfoSpace, and Russell C. Horowitz, Chief Executive
Officer of Go2Net, have met periodically since the fall of 1997 to discuss
potential business development activities between the two companies. In late
fall of 1999, Mr. Horowitz and Mr. Jain discussed generally the synergies and
the low degree of redundancy between the two businesses.

  At this meeting in the fall of 1999, Mr. Horowitz and Mr. Jain exchanged
preliminary due diligence information between the two companies.

  In December of 1999, InfoSpace experienced a material increase in its stock
price, and, therefore, the parties agreed to terminate their discussions about
a potential combination of the two companies at that time.

  In May 2000, Mr. Horowitz and Mr. Jain discussed potential business
development opportunities between Go2Net payment processing technologies and
InfoSpace storefront technology. Mr. Horowitz and Mr. Jain also discussed
business opportunities along the lines of distribution of a Go2Net desktop
portal through InfoSpace's wireless distribution network. Mr. Horowitz and Mr.
Jain agreed to meet in person to continue the discussions around the business
development of these two ideas.

  Mr. Horowitz and Mr. Jain met in late May 2000. At the meeting, Mr. Jain
introduced Arun Sarin, the new Chief Executive Officer of InfoSpace, to Mr.
Horowitz. While continuing the earlier discussion of potential business
development opportunities, Mr. Sarin suggested that rather than pursue business
development opportunities, the two companies should consider a merger. Mr.
Horowitz agreed that while conceptually a merger was a logical conclusion, no
discussions along these lines could be had unless InfoSpace was willing to
consider a transaction at a consideration amount that would be compelling to
the Go2Net stockholders.

  In late June 2000, Mr. Jain and Mr. Sarin phoned Mr. Horowitz and indicated
that InfoSpace would be interested in pursuing a business combination with
Go2Net. During the week of July 3, the parties engaged in preliminary
discussions regarding the proposed business combination.

  On July 7, 2000, Mr. Horowitz sent an informal e-mail memo to the Go2Net
board of directors soliciting their approval to move forward with negotiations
regarding a possible business combination of Go2Net and InfoSpace.

  Also on July 7, 2000, representatives of InfoSpace presented a draft non-
disclosure agreement. The parties negotiated the non-disclosure agreement over
the next several days and signed it on July 12, 2000.

  Also on July 7, 2000, InfoSpace retained Morgan Stanley & Co., Incorporated
as its financial advisor with respect to the merger. InfoSpace's board
subsequently ratified this engagement and InfoSpace entered into an engagement
letter with Morgan Stanley & Co. dated July 24, 2000.

  On July 9, 2000, Messrs. Horowitz, Jain and Sarin as well as Rand Rosenberg,
Chief Financial Officer of InfoSpace, met to explore a potential strategic
transaction further.

  On July 10, 2000, Mr. Rosenberg had a teleconference with Michael J. Riccio,
Jr., Chief Operating Officer of Go2Net, to discuss conducting due diligence.

                                       44
<PAGE>

  Also on July 10, 2000, Go2Net met with representatives of Merrill Lynch & Co.
to discuss the possibility of Merrill Lynch acting as its financial advisor
with respect to the merger. Go2Net's board subsequently ratified this
engagement, and Go2Net entered into an engagement letter with Merrill Lynch &
Co. dated July 17, 2000.

  In the period between July 12 and July 17, a series of meetings were held
between the executives of both companies for the purpose of conducting due
diligence. Representatives of Morgan Stanley & Co. and Merrill Lynch & Co.
attended these meetings.

  On July 12, 2000, Wilson Sonsini Goodrich & Rosati, as legal representative
of InfoSpace, and Hutchins, Wheeler & Dittmar, as legal representative of
Go2Net, participated in several conference calls regarding the logistics of
conducting the due diligence process. Representatives of both parties conducted
their business, legal, accounting and financial due diligence in Seattle
between July 12 and July 23, 2000. During this period, senior management of
both companies held numerous discussions regarding various business, financial,
operational and technical issues.

  On July 14, 2000, the InfoSpace board of directors met to discuss the merger.
Representatives of Wilson Sonsini Goodrich & Rosati attended the meeting, which
included a presentation of the financial analysis performed by Morgan Stanley &
Co. regarding the merger.

  On July 18, 2000, Go2Net's board of directors, together with senior
management of Go2Net and representatives of Hutchins, Wheeler & Dittmar and
Merrill Lynch & Co., held an extensive discussion regarding some of the
relative merits and risks of the potential transaction, including financial
analyses of the two companies and the possible synergies of the potential
combined company. Hutchins, Wheeler & Dittmar outlined the directors' legal
duties and responsibilities in connection with considering the merger. The
Go2Net board decided to continue discussions with InfoSpace about a possible
transaction.

  On July 18, 2000, Wilson Sonsini Goodrich & Rosati distributed a draft of the
merger agreement and related agreements.

  On July 19, 2000, Messrs. Jain, Sarin, Rosenberg, Horowitz and Riccio, as
well as representatives of Morgan Stanley & Co. met in San Mateo, California to
discuss potential synergies that might be present in the combined company.
Merrill Lynch & Co. separately held extensive discussions with members of
Go2Net management regarding potential synergies that might result from the
merger.

  On July 20, 2000, Hutchins, Wheeler & Dittmar provided its initial comments
on the draft merger agreement. From July 20, 2000 until July 26, 2000,
representatives of Wilson Sonsini Goodrich & Rosati and Hutchins, Wheeler &
Dittmar participated in a series of negotiations on the terms of the merger
agreement and related agreements.

  On July 21, 2000, the InfoSpace board of directors met to further discuss the
merger and the financial analyses performed by Morgan Stanley & Co. regarding
the merger. Management of InfoSpace presented the results of their due
diligence and Wilson Sonsini Goodrich & Rosati discussed the status of
negotiations regarding the merger agreement.

  On July 22, 2000, Go2Net's board members held a telephonic board meeting to
review drafts of the merger agreement and related agreements. During the call,
representatives of Merrill Lynch & Co. and Hutchins, Wheeler & Dittmar reviewed
and discussed with Go2Net's board the material terms of the draft merger
agreement. In particular, Go2Net's board reviewed the proposed termination
fees, opportunity to entertain alternative proposals and termination rights.
Representatives of Merrill Lynch & Co. made a presentation to Go2Net's board
regarding the financial analyses Merrill Lynch & Co. had performed regarding
Go2Net, InfoSpace and the merger. The Go2Net board reviewed the status of the
negotiations and directed management to continue negotiations with InfoSpace.

  On July 25, 2000, the InfoSpace board met to further discuss the financial
analyses prepared by Morgan Stanley & Co. regarding the merger. Mr. Rosenberg
discussed the results of financial due diligence

                                       45
<PAGE>

performed at Go2Net, and Wilson Sonsini Goodrich & Rosati discussed the
fiduciary duties of the board and legal issues related to the merger.

  On July 26, 2000, the InfoSpace board held a special meeting and approved the
proposed exchange ratio of the transaction, the issuance of the InfoSpace
common stock in the merger, the merger agreement and related agreements. Morgan
Stanley & Co. rendered an oral opinion, subsequently confirmed by delivery of a
written opinion, dated July 26, 2000, that, as of such date, the exchange ratio
provided in the merger agreement was fair to InfoSpace from a financial point
of view.

  On July 26, 2000, Go2Net's board also held a special meeting to analyze and
approve the final terms of the merger agreement and related agreements. Merrill
Lynch & Co. rendered an oral opinion, subsequently confirmed by delivery of a
written opinion dated July 26, 2000, that, as of that date, the exchange ratio
provided in the merger agreement was fair to the Go2Net stockholders, other
than InfoSpace and its affiliates, from a financial point of view. Go2Net's
board unanimously approved the final terms of the merger agreement and the
related agreements and resolved to recommend that the Go2Net stockholders adopt
the merger agreement and approve the merger.

  The merger agreement and related documents were signed by the parties on July
26, 2000. On the evening of July 26, 2000, after the close of the market,
InfoSpace and Go2Net issued a joint press release announcing the transaction.

Recommendation of InfoSpace's board of directors and InfoSpace's reasons for
the merger

  At a meeting held on July 26, 2000, the board of directors of InfoSpace
concluded that the merger was in the best interests of InfoSpace and its
stockholders and determined to recommend that the InfoSpace stockholders
approve the issuance of the shares of InfoSpace common stock in the merger. The
summary set forth below briefly describes certain of the reasons, factors and
information taken into account by the InfoSpace board in reaching its
conclusion. The InfoSpace board did not assign any relative or specific weights
to the factors considered in reaching such determination, and individual
directors may have given differing weights to different factors.

  In reaching its determination, the InfoSpace board consulted with InfoSpace's
management and legal and financial advisors, and carefully considered a number
of factors, including:

  . The potential strategic benefits of the merger;

  . Historical information concerning InfoSpace's and Go2Net's respective
    businesses, prospects, financial performance and condition, operations,
    technology, management and competitive position, including public reports
    concerning results of operations for each company filed with the SEC;

  . InfoSpace management's view of the financial condition, results of
    operations and businesses of InfoSpace and Go2Net before and after giving
    effect to the merger;

  . Current financial market conditions and historical market prices,
    volatility and trading information with respect to InfoSpace's common
    stock and Go2Net's common stock;

  . The benefits to be received by InfoSpace and the dilution to InfoSpace's
    stockholders in the merger and the relationship between the current and
    historical market values of InfoSpace's common stock and Go2Net's common
    stock and a comparison of comparable merger transactions;

  . The belief that the terms of the merger agreement, including the parties'
    respective representations, warranties and covenants, and the conditions
    to their respective obligations, are reasonable;

  . The prospects of InfoSpace independent of Go2Net;

  . The potential for other parties to enter into strategic relationships
    with or to acquire InfoSpace or Go2Net;

                                       46
<PAGE>

  . Detailed financial analysis and pro forma and other information with
    respect to the companies presented to the board, including the opinion of
    Morgan Stanley that the exchange ratio pursuant to the merger was fair
    from a financial point of view to InfoSpace. This opinion is subject to
    assumptions and limitations noted in the opinion and described under
    "Opinion of InfoSpace's Financial Advisor," and you should carefully read
    both that section and the opinion that is attached to this document as
    Annex B;

  . The expectation that the merger will be treated as a tax-free
    reorganization for federal income tax purposes;

  . The impact of the merger on InfoSpace's customers and employees; and

  . Reports from management, legal and financial advisors as to the results
    of the due diligence investigation of Go2Net.

  In its decision to recommend and approve the merger and the share issuance,
the most important benefits identified by the board of directors of InfoSpace
were the following:

  . InfoSpace management believes that, given the complementary nature of the
    technologies and business strategies of InfoSpace and Go2Net, the merger
    will enhance the opportunity for the potential realization of InfoSpace's
    strategic objectives;

  . InfoSpace's stockholders would have the opportunity to participate in the
    potential for growth of the combined company after the merger;

  . The combination of Go2Net's applications and technology infrastructure
    for both narrowband and broadband with InfoSpace's merchant and consumer
    infrastructure services for wireless and other platforms will allow the
    combined company to offer an end-to-end integrated platform of
    applications and technologies across the narrowband and broadband
    platforms;

  . The combination of InfoSpace's and Go2Net's merchant bases and merchant
    services will allow the combined company to distribute a more complete
    solution to a wider merchant network;

  . Go2Net's broadband technologies and applications will facilitate
    InfoSpace's entry into the broadband market;

  . The broader customer base of the combined company will allow it to
    mitigate the risk of customer concentration to which InfoSpace is
    currently exposed;

  . The stronger financial position of the combined company; and

  . The depth of experience provided by the combined management team.

  Potential risks or other negative factors identified by the InfoSpace board
of directors include the following:

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

  . The challenges of integrating the management teams, strategies, cultures
    and organizations of the two companies;

  . The risk of disruption of sales momentum as a result of uncertainties
    created by the announcement of the merger;

  . The risk that the merger might not be consummated despite the parties'
    efforts, even if approved by each company's stockholders;

  . If the merger is not accounted for as a pooling-of-interests, the
    significant adverse impact to the net income of the combined company that
    will arise due to the amortization of goodwill and other intangibles in
    light of the impact of purchase accounting for the merger;

                                       47
<PAGE>

  . The substantial charges to be incurred in connection with the merger,
    including costs of integrating the businesses and transaction expenses
    arising from the merger;

  . The effect of public announcement of the merger and the possibility that
    the merger might not be consummated on (a) InfoSpace's sales and
    operating results, (b) InfoSpace's ability to attract and retain key
    management, marketing and technical personnel and (c) progress of certain
    development projects; and

  . Other applicable risks described in the section of this joint proxy
    statement/prospectus entitled "Risk Factors" (see page 10).

  The foregoing discussion of the information and factors considered by the
InfoSpace board of directors is not intended to be exhaustive but includes
material factors considered by the InfoSpace board of directors. In view of the
complexity and wide variety of information and factors, both positive and
negative, considered by the InfoSpace board of directors, it did not find it
practical to quantify, rank or otherwise assign relative or specific weights to
the factors considered. In addition, the InfoSpace board did not reach any
specific conclusion with respect to each of the factors considered, or any
aspect of any particular factor. Instead, the InfoSpace board of directors
conducted an overall analysis of the factors described above, including
discussions with InfoSpace's management and legal, financial and accounting
advisors. In considering the factors described above, individual members of the
InfoSpace board of directors may have given different weight to different
factors.

  The InfoSpace board considered all these factors as a whole and believed the
factors supported its determination to approve the merger.

  After taking into consideration all of the factors set forth above,
InfoSpace's board of directors unanimously concluded that the merger was fair
to, and in the best interests of, InfoSpace and its stockholders and that
InfoSpace should proceed with the merger.

Recommendation of Go2Net's board of directors and Go2Net's reasons for the
merger

  The board of directors of Go2Net unanimously concluded that the merger
agreement and the merger are fair to and in the best interests of Go2Net and
its stockholders. The Go2Net board determined to recommend that the
stockholders approve the merger and adopt the merger agreement. This decision
was based upon several potential benefits of the merger that Go2Net's board
believes will contribute to the success of the combined company compared to
Go2Net continuing to operate as an independent business. The Go2Net board
believes that reasons the merger will be beneficial to Go2Net and its
stockholders include the following:

  . the ability of the two companies to combine their product lines to create
    a leading infrastructure provider offering an end-to-end integrated
    platform of applications across narrowband and broadband platforms;

  . InfoSpace's wireless technologies and applications will facilitate
    Go2Net's entry into the wireless market;

  . the increased customer base of the combined company;

  . the potential revenue synergies including cross-selling opportunities for
    the products of both companies;

  . Go2Net's stockholders would have the opportunity to participate in the
    future growth potential for the combined company following the merger;

  . Go2Net management believes that, given the complementary nature of the
    technologies and business strategies of Go2Net and InfoSpace, the merger
    will enhance the opportunity for the potential realization of Go2Net's
    strategic objectives;

                                       48
<PAGE>

  . the strong financial position of the combined company; and

  . the premium over the market price for their Go2Net common stock
    immediately prior to the announcement of the merger that Go2Net
    stockholders would have an opportunity to receive.

  Go2Net's board reviewed a number of factors in evaluating the merger,
including, but not limited to, the following:

  . information concerning InfoSpace's business, financial performance and
    condition, operations and management;

  . information concerning the financial condition, results of operations and
    businesses of InfoSpace and Go2Net before and after giving effect to the
    merger;

  . current financial market conditions and historical market prices,
    volatility and trading information with respect to InfoSpace common stock
    and Go2Net common stock;

  . the consideration InfoSpace will issue in the merger in light of
    comparable merger transactions;

  . the belief that the terms of the merger agreement and related agreements
    are reasonable;

  . the ability of Go2Net's board, in exercise of its fiduciary duties in
    accordance with the merger agreement, to authorize Go2Net to provide
    information to, engage in negotiations with and, subject to the payment
    of a termination fee, enter into a transaction with another party as
    described under "The Merger Agreement;"

  . the impact of the merger on the customers and employees of Go2Net and the
    combined company;

  . results of the due diligence investigation conducted by Go2Net's
    management, financial advisors and legal counsel; and

  . the analyses and presentations prepared by Merrill Lynch & Co. and
    Merrill Lynch's written opinion (the full text of which is attached as
    Annex C to this joint proxy statement/prospectus) to the effect that, as
    of July 26, 2000, and based upon and subject to the qualifications,
    assumptions and limitations set forth in its opinion, the exchange ratio
    was fair to Go2Net's stockholders, other than InfoSpace and its
    affiliates, from a financial point of view.

  The Go2Net board also identified and considered a number of potentially
negative factors in its deliberations concerning the merger including the
following:

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

  . the risk that the merger may not be consummated, notwithstanding the
    voting agreements obtained from holders of Go2Net capital stock and
    holders of InfoSpace common stock;

  . the risk of management and employee disruption associated with the
    merger, including that despite the efforts of the combined company, key
    technical, sales and management personnel might not remain employed by
    the combined company; and

  . other applicable risks described in this joint proxy statement/prospectus
    under "Risk Factors."

  The foregoing discussion of the information and factors considered by the
Go2Net board of directors is not intended to be exhaustive but includes
material factors considered by the Go2Net board of directors. In view of the
complexity and wide variety of information and factors, both positive and
negative, considered by the Go2Net board of directors, it did not find it
practical to quantify, rank or otherwise assign relative or specific weights to
the factors considered. In addition, the Go2Net board did not reach any
specific conclusion with respect to each of the factors considered, or any
aspect of any particular factor. Instead, the Go2Net board of directors
conducted an overall analysis of the factors described above, including
discussions with Go2Net's management and legal, financial and accounting
advisors. In considering the factors described above, individual members of the
Go2Net board of directors may have given different weight to different factors.

                                       49
<PAGE>

  The Go2Net board considered all these factors as a whole and believed the
factors supported its determination to approve the merger.

  After taking into consideration all of the factors set forth above, Go2Net's
board of directors unanimously concluded that the merger was fair to, and to
the best interests of, Go2Net and its stockholders (other than InfoSpace and
its affiliates) and that Go2Net should proceed with the merger.

Opinion of InfoSpace's financial advisor

  Under an engagement letter dated July 24, 2000, InfoSpace retained Morgan
Stanley & Co. Incorporated to provide financial advisory services and a
financial fairness opinion in connection with the merger. InfoSpace's board of
directors selected Morgan Stanley to act as InfoSpace's financial advisor based
on Morgan Stanley's qualifications, expertise and reputation and its knowledge
of Internet and Internet infrastructure industries. At a telephonic meeting of
InfoSpace's board of directors on July 26, 2000, Morgan Stanley rendered its
oral opinion, subsequently confirmed in writing, that, as of July 26, 2000 and
based upon and subject to the various considerations set forth in the written
opinion, the exchange ratio pursuant to the merger agreement was fair to
InfoSpace from a financial point of view.

  The full text of the written opinion of Morgan Stanley, dated July 26, 2000,
is attached as Annex B to this document and sets forth, among other things, the
assumptions made, procedures followed, matters considered and limitations on
the scope of the review undertaken by Morgan Stanley in rendering its opinion.
InfoSpace stockholders are urged to, and should, read the opinion carefully and
in its entirety. Morgan Stanley's opinion is directed to InfoSpace's board of
directors and addresses only the fairness to InfoSpace from a financial point
of view of the exchange ratio pursuant to the merger agreement as of the date
of the opinion. It does not address any other aspect of the merger and does not
constitute a recommendation to any holder of InfoSpace common stock or Go2Net
common stock as to how to vote at either the InfoSpace special meeting or the
Go2Net special meeting.

The summary of the opinion of Morgan Stanley set forth in this document is
qualified in its entirety by reference to the full text of the written opinion.

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

  (i)     reviewed certain publicly available financial statements and other
          information of Go2Net and InfoSpace;

  (ii)    reviewed certain internal financial statements and other financial
          and operating data concerning Go2Net prepared by the management of
          Go2Net;

  (iii)   reviewed certain financial projections prepared by the management
          of Go2Net;

  (iv)    reviewed certain internal financial statements and other financial
          and operating data concerning InfoSpace prepared by the management
          of InfoSpace;

  (v)     reviewed certain financial projections prepared by the management
          of InfoSpace;

  (vi)    reviewed the past and current operations and financial condition
          and the prospects of Go2Net and InfoSpace, including information
          relating to certain strategic, financial and operational benefits
          anticipated from the merger, with senior executives of Go2Net and
          InfoSpace, respectively;

  (vii)   reviewed the pro forma impact of the merger on InfoSpace's
          financial performance, including revenue per share and earnings per
          share;

  (viii)  reviewed the reported prices and trading activity for Go2Net common
          stock and InfoSpace common stock;

                                       50
<PAGE>

  (ix)    compared the financial performance of Go2Net and InfoSpace and the
          prices and trading activity of Go2Net common stock and InfoSpace
          common stock with that of certain other publicly-traded companies
          comparable with Go2Net and InfoSpace, respectively, and their
          securities;

  (x)     reviewed the financial terms, to the extent publicly available, of
          certain comparable acquisition transactions;

  (xi)    participated in discussions and negotiations among representatives
          of Go2Net and InfoSpace and their financial and legal advisors;

  (xii)   reviewed a draft of the merger agreement dated July 26, 2000, and
          certain related documents; and

  (xiii)  performed such other analyses and considered such other factors as
          we have deemed appropriate.

  Morgan Stanley assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by it for the purposes of
its opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from the merger, Morgan Stanley assumed that they were reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance of Go2Net and InfoSpace, respectively. In
addition, Morgan Stanley assumed that the merger will be consummated in
accordance with the terms set forth in the draft merger agreement dated July
26, 2000, including that the merger will be treated as a tax-free
reorganization and/or exchange, each pursuant to the Internal Revenue Code of
1986.

  Morgan Stanley relied upon, without independent verification, the assessment
by the management of Go2Net and InfoSpace of the strategic benefits expected to
result from the transaction. Morgan Stanley also relied upon, without
independent verification, the assessment by the management of Go2Net and
InfoSpace of the technologies and products of Go2Net and InfoSpace, the timing
and risks associated with the integration of Go2Net and InfoSpace and the
validity of, and risks associated with, Go2Net's and InfoSpace's existing and
future products and technologies.

  Morgan Stanley did not make any independent valuation or appraisal of the
assets or liabilities of Go2Net or InfoSpace, nor was Morgan Stanley furnished
with any such appraisals. Morgan Stanley's opinion is necessarily based on
financial, economic, market and other conditions as in effect on, and the
information made available to Morgan Stanley as of, the date of its opinion.

  The following is a brief summary of certain of the analyses performed by
Morgan Stanley in connection with its oral opinion and the preparation of its
written opinion dated July 26, 2000. Certain of these summaries of financial
analyses include information presented in tabular format. In order to
understand fully the financial analyses used by Morgan Stanley, the tables must
be read together with the text of each summary. The tables alone do not
constitute a complete description of the financial analyses.

  Exchange Ratio Analysis. Morgan Stanley reviewed the ratios of the closing
prices of Go2Net common stock to the corresponding closing prices of InfoSpace
common stock over various periods from July 24, 1999 through July 24, 2000.
Morgan Stanley examined the premiums represented by the exchange ratio of
1.820x over the averages of these daily ratios over various periods:

Go2Net

  Trading Range. Morgan Stanley reviewed the range of closing prices of Go2Net
common stock prior to July 24, 2000. Morgan Stanley observed the following:

  Comparable Company Trading Analysis. Morgan Stanley compared certain publicly
available financial information of Go2Net with publicly available information
for selected companies comparable to the business or businesses of Go2Net. The
following table lists the relevant comparable companies analyzed by Morgan
Stanley:

Go2Net Comparable Companies

  America Online, Inc.
  Yahoo! Inc.
  Excite@Home Corporation
  OpenTV Corp.
  Exodus Communications, Inc.
  Inktomi Corporation
  Critical Path, Inc.

  In conducting its analysis, Morgan Stanley applied the relevant financial
multiples of the comparable companies to publicly available securities research
analyst estimates of various financial statistics for Go2Net. Morgan Stanley
then estimated the implied value per share of Go2Net as of July 24, 2000.
Morgan Stanley estimated the following:

<TABLE>

     2001 Estimated Revenues................   15.0x-40.0x        $53-$128
</TABLE>

  Based on the comparable company analysis, Morgan Stanley estimated an implied
value range per share of Go2Net of $50 to $126.

  No company utilized in the comparable company analysis is identical to Go2Net
or InfoSpace. In evaluating the comparable companies, Morgan Stanley made
judgments and assumptions with regard to industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of Go2Net and InfoSpace, such as the impact of
competition on the businesses of Go2Net or InfoSpace and the industry in
general, industry growth and the absence of any material adverse change in the
financial condition and prospects of Go2Net or InfoSpace or the industry or in
the financial markets in general. Mathematical analysis, such as determining
the average or median, is not in itself a meaningful method of using comparable
company data.

  Precedent Transactions Analysis. Based on publicly available information as
of July 24, 2000, Morgan Stanley compared the premiums paid in selected
precedent merger and acquisition transactions to the relevant financial
statistics for Go2Net implied by the exchange ratio and the share price of
InfoSpace common stock as of July 24, 2000. The following table presents
certain of the precedent transactions analyzed by Morgan Stanley:

   90-day Average Exchange Ratio................ 10.0%-80.0%      $47-$77
</TABLE>

  No transaction utilized in the precedent transactions analysis is identical
to the merger. In evaluating the transactions listed above, Morgan Stanley made
judgments and assumptions with regard to industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of InfoSpace and Go2Net, such as the impact of
competition on the businesses of Go2Net or InfoSpace and the industry in
general, industry growth and the absence of any material adverse change in the
financial condition and prospects of InfoSpace or Go2Net or the industry or in
the financial markets in general. Mathematical analysis, such as determining
the average or median, is not in itself a meaningful method of using comparable
transaction data.

  Relative Contribution. Morgan Stanley analyzed the relative contributions of
certain financial statistics of Go2Net and InfoSpace to the pro forma financial
performance of the combined company based on selected financial statistics. The
relevant information for Go2Net and InfoSpace was obtained from selected
research analyst estimates available as of July 24, 2000. Morgan Stanley then
compared the pro forma ownership of Go2Net implied by the relative contribution
analysis to the pro forma ownership of Go2Net implied by the exchange ratio.
Morgan Stanley observed the following:

value analysis to estimate the present value per share of Go2Net. The
projections of financial performance were based on securities research analyst
estimates available as of July 24, 2000.

the merger on InfoSpace's combined projected revenues per share and earnings
per share for the calendar year 2000 and 2001 and for each quarter from
calendar fourth quarter 2000 through calendar fourth quarter 2001. Such
analysis was based on projections by securities research analysts for InfoSpace

  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Morgan Stanley considered the results of all of its analyses as
a whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, Morgan Stanley believes that selecting any
portion of its analyses, without considering all analyses, would create an
incomplete view of the process underlying its opinion. In addition, Morgan
Stanley may have given various analyses and factors more or less weight than
other analyses and factors, and may have deemed various assumptions more or
less probable than other assumptions, so that the ranges of valuations
resulting from any particular analysis described above should not be taken to
be Morgan Stanley's view of the actual value of InfoSpace or Go2Net. In
performing its analyses, Morgan Stanley made numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, many of which are beyond the control of InfoSpace or Go2Net. Any
estimates contained in Morgan Stanley's analyses are not necessarily indicative
of future results or actual values, which may be significantly more or less
favorable than those suggested by such estimates.

  The analyses performed were prepared solely as part of Morgan Stanley's
analysis of the fairness from a financial point of view to InfoSpace of the
exchange ratio pursuant to the merger agreement and were conducted in
connection with the delivery of Morgan Stanley's opinion. The analyses do not
purport to be appraisals or to reflect the prices at which InfoSpace or Go2Net
might actually be sold.

  The exchange ratio pursuant to the merger agreement was determined through
arm's-length negotiations between InfoSpace and Go2Net and was approved by the
InfoSpace board of directors. Morgan Stanley provided advice to InfoSpace
during such negotiations; however, Morgan Stanley did not recommend any
specific form or amount of consideration to InfoSpace or that any specific form
or amount of consideration constituted the only appropriate form or amount of
consideration in connection with the merger.

                                       55
<PAGE>

  In addition, Morgan Stanley's opinion and presentation to the InfoSpace board
of directors was one of many factors taken into consideration by InfoSpace's
board of directors in making its decision to approve the merger. Consequently,
the Morgan Stanley analyses as described above should not be viewed as
determinative of the opinion of the InfoSpace board of directors with respect
to the merger or of whether the InfoSpace board of directors would have been
willing to agree to a transaction with a different form or amount of
consideration.

  The InfoSpace board of directors retained Morgan Stanley based upon Morgan
Stanley's qualifications, experience and expertise. Morgan Stanley is an
internationally recognized investment banking and advisory firm. Morgan
Stanley, as part of its investment banking business, is continuously engaged in
the valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate, estate and other purposes. In the ordinary course of
Morgan Stanley's trading and brokerage activities, Morgan Stanley or its
affiliates may at any time hold long or short positions, may trade or otherwise
effect transactions, for its own account or for the account of customers in the
securities of InfoSpace, Go2Net or any of the other parties to the transaction.

  Under the engagement letter, Morgan Stanley provided financial advisory
services and the financial fairness opinion in connection with the merger, and
InfoSpace agreed to pay Morgan Stanley a customary fee. In addition, InfoSpace
has agreed to reimburse Morgan Stanley for any out-of-pocket expenses incurred
by Morgan Stanley in connection with its engagement and to indemnify Morgan
Stanley and its affiliates, their respective directors, officers, agents and
employees and each person, if any, controlling Morgan Stanley or any of its
affiliates against certain liabilities and expenses, including certain
liabilities under the federal securities laws, related to or arising out of
Morgan Stanley's engagement.

Opinion of Go2Net's financial advisor

  Go2Net retained Merrill Lynch, Pierce, Fenner & Smith Incorporated to act as
its financial advisor with respect to the merger. In connection with that
engagement, Go2Net requested that Merrill Lynch evaluate the fairness, from a
financial point of view, to the holders of shares of Go2Net common stock (other
than InfoSpace and its affiliates) of the exchange ratio in the merger. At the
meeting of the board of directors of Go2Net on July 26, 2000, Merrill Lynch
rendered its oral opinion to the board of directors of Go2Net, subsequently
confirmed in writing, that as of July 26, 2000, based upon the assumptions
made, matters considered and limits of such review, as set forth in its
opinion, the exchange ratio in the merger was fair to the holders of shares of
Go2Net common stock (other than InfoSpace and its affiliates), from a financial
point of view.

  The full text of Merrill Lynch's opinion, which sets forth material
information relating to Merrill Lynch's opinion that the exchange ratio was
fair, from a financial point of view, to holders of Go2Net common stock (other
than InfoSpace and its affiliates), including the assumptions made, matters
considered and qualifications and limitations on the scope of review undertaken
by Merrill Lynch, is attached as Annex C and is incorporated in this joint
proxy statement/prospectus by reference. This description of Merrill Lynch's
opinion should be reviewed together with the full text of the opinion, and
stockholders of Go2Net are urged to read the opinion and consider it carefully.
Merrill Lynch's opinion is addressed to Go2Net's board of directors and
addresses only the fairness, from a financial point of view, of the exchange
ratio in the merger to the holders of Go2Net common stock (other than InfoSpace
and its affiliates). The terms of the merger, including the exchange ratio,
were determined through negotiations between Go2Net and InfoSpace and were not
determined or recommended by Merrill Lynch. Merrill Lynch's opinion does not
address the merits of the underlying decision of Go2Net to engage in the merger
and does not constitute, nor should it be construed as, a recommendation to any
stockholder of Go2Net or InfoSpace as to how to vote on the merger or any
matter related to the merger.

  In arriving at its opinion, Merrill Lynch, among other things:

  (1) Reviewed certain publicly available business and financial information
      relating to Go2Net and InfoSpace that Merrill Lynch deemed to be
      relevant;

  (2) Reviewed certain information, including financial forecasts, relating
      to the business, earnings, cash flow, assets and liabilities and
      prospects of Go2Net and InfoSpace, furnished to it or discussed with it
      by Go2Net and InfoSpace;

  (3) Conducted discussions with members of senior management of Go2Net and
      InfoSpace concerning their respective businesses and prospects, and
      potential financial benefits of the merger;

  (4) Reviewed the historical market prices and trading activity for Go2Net
      common stock and InfoSpace common stock and compared them with that of
      certain publicly traded companies which Merrill Lynch deemed to be
      reasonably similar to Go2Net and InfoSpace, respectively;

  (5) Compared the results of operations of Go2Net and InfoSpace with those
      of certain companies which Merrill Lynch deemed to be reasonably
      similar to Go2Net and InfoSpace, respectively;

  (6) Compared the proposed financial terms of the transactions contemplated
      by the merger agreement with the financial terms of certain other
      mergers and acquisitions which Merrill Lynch deemed to be relevant;

  (7) Reviewed the merger agreement; and

  (8) Reviewed such other financial studies and analyses and performed such
      other investigations and took into account such other matters as
      Merrill Lynch deemed necessary, including its assessment of general
      economic, market and monetary conditions.

  In preparing its opinion, Merrill Lynch assumed and relied on the accuracy
and completeness of all information supplied or otherwise made available to it,
discussed with or reviewed by or for it, or publicly available, and Merrill
Lynch did not assume any responsibility for independently verifying such
information or undertaking an independent evaluation or appraisal of any of the
assets or liabilities of InfoSpace or Go2Net, nor was Merrill Lynch furnished
with any such evaluation or appraisal. In addition, Merrill Lynch did not
assume any obligation to conduct, nor did Merrill Lynch conduct any physical
inspection of the properties or facilities of InfoSpace or Go2Net. Neither
Go2Net nor InfoSpace made available to Merrill Lynch any internal management
forecasts of future financial performance. For purposes of its analysis,
Merrill Lynch used the publicly available estimates of certain research
analysts and Merrill Lynch assumed, with consent of the respective managements
of Go2Net and InfoSpace, that such estimates had been reasonably prepared and
reflected the best then available estimates of Go2Net's and InfoSpace's future
financial performance. Merrill Lynch further assumed that the merger would
qualify as a tax-free reorganization for United States federal income tax
purposes. Merrill Lynch also assumed that the final form of the merger
agreement would be substantially similar to the drafts made available to and
reviewed by Merrill Lynch.

  Merrill Lynch's opinion was necessarily based upon market, economic and other
conditions as they existed and could be evaluated on the date of the Merrill
Lynch opinion, and on the information made available to Merrill Lynch as of the
date of the opinion. According to the terms of its engagement by Go2Net,
Merrill Lynch has no obligation to update its opinion to take into account
events occurring after the date that its opinion was delivered to Go2Net's
board of directors. As a result, circumstances could develop prior to
consummation of the merger that, if known at the time Merrill Lynch rendered
its opinion, would have altered such opinion. Merrill Lynch expresses no
opinion as to the prices at which shares of Go2Net common stock or InfoSpace
common stock will trade following the announcement or consummation of the
merger.

  The matters considered by Merrill Lynch in arriving at its opinion are based
on numerous macroeconomic, operating and financial assumptions with respect to
industry performance, general business and economic conditions, many of which
are beyond the control of InfoSpace and Go2Net, and involve the

                                       57
<PAGE>

application of complex methodologies and educated judgment. Any estimates
incorporated in the analyses performed by Merrill Lynch are not necessarily
indicative of actual past or future results or values, which may be
significantly more or less favorable than these estimates. Estimated values do
not purport to be appraisals and do not necessarily reflect the prices at which
businesses or companies may be sold in the future.

  At the meeting of Go2Net's board of directors held on July 26, 2000, Merrill
Lynch presented certain financial analyses accompanied by written materials in
connection with the delivery of its oral opinion at that meeting and its
subsequent written opinion. The following is a summary of certain material
financial analyses performed by Merrill Lynch in arriving at its opinion.

Premiums Analysis

  Premium to Historical Stock Price and Exchange Ratio. Merrill Lynch reviewed,
over various periods, both the average closing stock price of Go2Net as well as
the average historical exchange ratio of the Go2Net common share price to that
of the Infospace common share price. Merrill Lynch then reviewed the premiums
represented by the implied transaction offer price ($84.29) to the average
closing stock prices of Go2Net and the premiums represented by the transaction
exchange ratio (1.820x) to the average historical exchange ratios over such
periods:

</TABLE>

  Merrill Lynch observed that the implied offer price and the transaction
exchange ratio represented a premium range of 31.8% to 74.6% and 35.7% to
102.6% to the average closing price of Go2Net common stock and the historical
exchange ratio, respectively for the one day, ten day, one, three and six month
periods.

Go2Net

  Trading Analysis. Merrill Lynch reviewed the recent trading performance of
shares of Go2Net common stock. The per share closing price trading data for the
six, three and one month periods prior to and including the day prior to
announcement on July 26, 2000 are summarized in the table below:

<TABLE>
<CAPTION>
   Period                                                       Low ($) High ($)

   6 Months....................................................  36.00   97.00
   3 Months....................................................  36.00   62.13
   1 Month.....................................................  43.75   62.13
</TABLE>

  Merrill Lynch observed that the implied offer price for Go2Net was in the
range of the six month trading range and above the three and one month trading
performance of the Go2Net stock.

  Selected Public Trading Multiples. Using publicly available Wall Street
equity analyst forecasts and other information, Merrill Lynch compared selected
financial data of Go2Net with similar data for selected publicly traded
companies engaged in businesses that Merrill Lynch judged to be reasonably
comparable to Go2Net. These companies were:

  OpenTV, Corp.
  Yahoo!, Inc.
  Liberate Technologies, Inc.

                                       58
<PAGE>

  Lycos, Inc.
  LookSmart, Ltd.
  America Online, Inc.
  GoTo.com, Inc.
  Excite@Home Corporation
  AskJeeves, Inc.

  Merrill Lynch selected these companies because they engage in businesses
reasonably comparable to those of Go2Net. Merrill Lynch used publicly available
financial projections by equity analysts covering each comparable company to
determine the ratio of market capitalization to projected revenues for calendar
years 2000 and 2001 for each of these companies. The following table presents a
comparison of the mean and median revenue multiples of the comparable
companies.

<TABLE>
<CAPTION>
                                                                   Mean  Median
                                                                   ----- ------
   <S>                                                             <C>   <C>
   2000 Revenue Multiple.......................................... 34.8x 18.3x
   2001 Revenue Multiple.......................................... 22.5x 13.3x
</TABLE>

  Merrill Lynch observed that the implied multiples of 2000 and 2001 forecasted
revenue of Go2Net being paid by InfoSpace exceeded the mean and median of the
comparable company revenue multiples for each of 2000 and 2001.

  It should be noted that no company utilized in the analysis above is
identical to Go2Net. In evaluating companies identified by Merrill Lynch as
comparable to Go2Net, Merrill Lynch made judgments and assumptions with regard
to industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Go2Net,
such as the impact of competition on the business of Go2Net and the industry
generally, industry growth and the absence of any material change in the
financial condition and prospects of Go2Net or the industry or in the financial
markets in general. A complete analysis involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the comparable companies and other factors that could affect the public trading
values of such comparable companies to which they are being compared;
mathematical analysis (such as determining the mean or the median) is not in
itself a meaningful method of using selected company data.

  Equity Analyst Research Review. Using publicly available Wall Street equity
research analyst forecasts and other information, Merrill Lynch reviewed the
twelve-month stock price target estimates of certain Wall Street equity
research analysts. Utilizing a discount rate of 22.5% Merrill Lynch calculated
the implied current value of the Go2Net stock price based on such estimates.

<TABLE>
<CAPTION>
                                                             Low ($) High ($)

   Implied Current Wall Street Equity Research Value for
    Go2Net per Share........................................  61.25   106.25
</TABLE>

  Merrill Lynch observed that the implied offer price for Go2Net was in the
range of the implied current Wall Street equity research value for Go2Net per
share.

  Comparable Transaction Analysis. Using publicly available Wall Street equity
research analyst forecasts and other information, Merrill Lynch examined the
following transactions that Merrill Lynch deemed to be relevant to determine
the ratio of transaction value to projected next calendar year revenues where
"transaction value" is generally defined as the sum of the per share offer
price for the target company multiplied by the number of company shares
outstanding and the number of target company options outstanding, net of option
proceeds, plus the preferred equity at liquidation, if any, the short-term
debt, the long-term debt and any minority interests, less cash, marketable
securities and exercisable option proceeds. Merrill Lynch also calculated the
premiums paid to the one month average stock price of the companies acquired in
such transactions:

  SoftAware Networks/Digital Island, Inc.
  Lycos, Inc./Terra Networks, S.A.

                                       59

  Broadcast.com, Inc./Yahoo!, Inc.
  MovieFone, Inc./America Online, Inc.
  GeoCities/Yahoo!, Inc.
  Excite, Inc./@Home Corporation
  Shopping.com/Compaq Computer Corporation/AltaVista Company

  All multiples and premiums paid for the selected transactions were based on
public information available at the time of public announcement, and Merrill
Lynch's analysis did not take into account different market and other
conditions during the period in which the selected transactions occurred. The
comparable transaction analysis yielded the following mean and median multiples
of projected next calendar year revenues and premiums paid to the one month
average closing stock price of the acquired company:

<TABLE>
<CAPTION>
                                                                    Mean  Median
                                                                    ----  ------
   <S>                                                              <C>   <C>
   Transaction Value/Next CY Revenue............................... 23.6x  18.6x
   Premium Paid to 1 Month Average Closing Stock Price............. 57.0%  54.3%
</TABLE>

  Merrill Lynch observed that the implied transaction value to next calendar
year's revenue multiple for Go2Net as well as the implied offer price premium
over the one month average closing price of Go2Net's share price exceeded the
mean and median of the comparable transaction revenue multiples for next
calendar year and the premiums paid of the comparable transactions.

  It should be noted that no transaction utilized in the analysis above is
identical to the Go2Net-InfoSpace merger. A complete analysis involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies involved in these transactions and other
factors that could affect the transaction multiples or premiums paid in such
comparable transactions to which the merger is being compared; mathematical
analysis (such as determining the mean or the median) is not in itself a
meaningful method of using selected transaction data.

  Discounted Cash Flow Analysis. Merrill Lynch performed a discounted cash flow
analysis of Go2Net, without giving effect to the merger, for the years 2001
through 2005. Merrill Lynch calculated a range of equity values per share for
Go2Net based upon the sum of the discounted net present value of Go2Net's five-
year stream of projected unlevered free cash flows plus the discounted net
present value of the terminal value based on a range of multiples of its
projected 2006 revenue.

                                       60
<PAGE>

  Using discount rates ranging from 20% to 25% and terminal value multiples of
estimated 2006 revenue ranging from 10.0x to 15.0x, Merrill Lynch calculated
the following range of implied equity values per share for Go2Net common stock:

<TABLE>
<CAPTION>
                                                              Low ($) High ($)
                                                              ------- --------
   <S>                                                        <C>     <C>
   Implied Equity Value Per Share of Go2Net Common Stock.....  56.25   89.50
</TABLE>


  Merrill Lynch observed that the implied offer price for Go2Net was near the
high end of the range of the implied equity value per share of Go2Net common
stock as determined by the discounted cash flow analysis.

InfoSpace

  Trading Analysis. Merrill Lynch reviewed the recent common stock trading
performance of shares of InfoSpace. The per share closing price trading data
for the six, three and one month periods prior to and including the day prior
to announcement on July 26, 2000 are summarized in the table below:

<TABLE>
<CAPTION>

   3 Months....................................................  41.50    72.00
   1 Month.....................................................  43.38    59.25
</TABLE>

  Merrill Lynch observed that the InfoSpace share price one day prior to the
transaction announcement date, was in the low end of the range of the six
month, three and one month trading performance of the InfoSpace stock.

  Selected Public Trading Multiples. Using publicly available Wall Street
equity analyst forecasts and other information, Merrill Lynch compared selected
financial data of InfoSpace with similar data for selected publicly traded
companies engaged in businesses that Merrill Lynch judged to be reasonably
comparable to InfoSpace. These companies were:

  Aether Systems, Inc.
  Akamai Technologies, Inc.
  VeriSign, Inc.
  Software.com, Inc.
  Phone.com, Inc.
  Inktomi Corporation
  Portal Software, Inc.

  Merrill Lynch selected these companies because they engage in businesses
reasonably comparable to those of InfoSpace. Merrill Lynch used publicly
available financial projections by equity analysts covering each comparable
company to determine the ratio of market capitalization to projected calendar
year revenues for 2000 and 2001 for each of these companies. The following
table presents a comparison of the median revenue multiples of the comparable
companies.

<TABLE>
<CAPTION>
                                                                   Mean  Median

   2000 Revenue Multiple.......................................... 87.3x 65.2x
   2001 Revenue Multiple.......................................... 43.7x 43.8x
</TABLE>

  Merrill Lynch observed that the trading multiple of InfoSpace exceeded the
median and mean of the comparable company revenue multiples for each of 2000
and 2001.

  It should be noted that no company utilized in the analysis above is
identical to InfoSpace. In evaluating companies identified by Merrill Lynch as
comparable to InfoSpace, Merrill Lynch made judgments and

                                       61
<PAGE>

assumptions with regard to industry performance, general business, economic,
market and financial conditions and other matters, many of which are beyond the
control of InfoSpace, such as the impact of competition on the business of
InfoSpace and the industry generally, industry growth and the absence of any
material change in the financial condition and prospects of InfoSpace or the
industry or in the financial markets in general. A complete analysis involves
complex considerations and judgments concerning differences in financial and
operating characteristics of the comparable companies and other factors that
could affect the public trading values of such comparable companies to which
they are being compared; mathematical analysis (such as determining the mean or
the median) is not in itself a meaningful method of using selected company
data.

  Equity Analyst Research Review. Using publicly available Wall Street equity
analyst forecasts and other information, Merrill Lynch reviewed the twelve-
month stock price target estimates of certain Wall Street equity research
analysts. Utilizing a discount rate of 22.5% Merrill Lynch calculated the
implied current value of the InfoSpace stock price based on such estimates.

<TABLE>

   Implied Current Wall Street Equity Research Value for
    InfoSpace Per Share.....................................  81.75   126.50
</TABLE>

  Merrill Lynch observed that the InfoSpace share price, the day prior to the
transaction announcement, was below the range of the implied current value
share price as observed by Wall Street equity research analysts.

  Discounted Cash Flow Analysis. Merrill Lynch performed a discounted cash flow
analysis of InfoSpace, without giving effect to the merger, for the years 2001
through 2005. Merrill Lynch calculated a range of equity values per share for
InfoSpace based upon the sum of the discounted net present value of InfoSpace's
five-year stream of projected unlevered free cash flows plus the discounted net
present value of the terminal value based on a range of multiples of its
projected 2006 revenue.

  Using discount rates ranging from 20% to 25% and terminal value multiples of
estimated 2006 revenue ranging from 30.0x to 50.0x, Merrill Lynch calculated
the following range of implied equity values per share for InfoSpace common
stock:

<TABLE>

  Merrill Lynch observed that the InfoSpace share price, the day prior to the
transaction announcement, was within the low end of the range of the implied
equity value per share of InfoSpace common stock as determined by the
discounted cash flow analysis.

Relative Valuation Analysis

  Relative Historical Exchange Ratio Analysis. Merrill Lynch reviewed the
historical stock prices of Go2Net and InfoSpace common stock and the implied
market exchange ratios determined by dividing the closing price per share of
Go2Net common stock by the price per share of InfoSpace common stock. The
implied exchange ratios for the six, three and one month period up to and
including the day prior to the announcement on July 26, 2000 are summarized in
the table below:

of Go2Net common stock by the price per share of InfoSpace common stock for the
six, three and one month periods.

  Relative Equity Analyst Research Review. Merrill Lynch calculated the
exchange ratio implied by dividing the Implied Wall Street Equity research
current value per share of Go2Net by the implied Wall Street equity research
current value of InfoSpace per share (as calculated above). The implied low and
high exchange ratios are summarized as follows:

<TABLE>
<CAPTION>
                                                                  Low    High
                                                                 ------ ------
   <S>                                                           <C>    <C>
   Implied Exchange Ratio....................................... 0.484x 1.300x
</TABLE>

  Merrill Lynch observed that the offer exchange ratio exceeded the range of
implied exchange ratios determined by dividing the Implied Wall Street equity
research current value of Go2Net per share by the implied Wall Street equity
research current value of InfoSpace per share.

  Relative Contribution to Operating Results. Merrill Lynch analyzed the
relative contributions of revenue and earnings before interest, taxes,
depreciation and amortization, commonly known as EBITDA, for the forecasted
years 2001 and 2005 of Go2Net and InfoSpace to the combined entity. These
analyses were performed without taking into account any potential synergies
resulting from the merger. Using the forecasted revenue and EBITDA projections
and the treasury stock method of calculating shares outstanding for each
company Merrill Lynch observed the following range of implied exchange ratios:

<TABLE>
<CAPTION>
                                                                Low   High(1)
                                                               ------ -------
   <S>                                                         <C>    <C>
   Implied Exchange Ratio -- Contribution of 2001 and 2005
    Revenue and EBITDA........................................ 1.943x 4.327x
</TABLE>

  Merrill Lynch observed that the offer exchange ratio was below the range of
implied exchange ratios as calculated by the contribution of operating results
to the combined entity.

  Relative Growth Contribution to Operating Results. Merrill Lynch calculated
the relative contributions of the growth in revenue and EBITDA for the
forecasted period from 2001 to 2005 of Go2Net and InfoSpace to the combined
entity. Using the forecasted revenue and EBITDA projections for each company
Merrill Lynch observed the following range of implied exchange ratios:

<TABLE>
<CAPTION>
                                                                 Low    High
                                                                ------ ------

   Implied Exchange Ratio -- Revenue and EBITDA Growth
    Contribution from 2001 to 2005............................. 1.503x 3.005x
</TABLE>

  Merrill Lynch observed that the offer exchange ratio was in the range of the
implied exchange ratio as calculated by the growth contribution of operating
results to the combined entity.

  Comparable Transaction Exchange Premiums Analysis. Using publicly available
information, Merrill Lynch examined the following comparable transactions to
determine the premiums paid to the one-month average exchange ratio of the
companies acquired in such transactions:

  SoftAware Networks/Digital Island, Inc.
  Lycos, Inc./Terra Networks, S.A.
  Octane Software, Inc./E.piphany, Inc.

  The comparable transaction analysis yielded the following mean and median
percentage premiums paid:

                                                                    Mean  Median
                                                                    ----  ------

   Percentage Premiums Paid to One Month
    Average Exchange Ratio......................................... 47.7%  37.3%
</TABLE>

  Merrill Lynch observed that percentage premium to the one-month average
exchange ratio of Go2Net share price divided by InfoSpace share price was in
excess of both the mean and median premiums paid in comparable transactions. A
complete analysis involves complex considerations and judgments concerning
differences in financial and operating characteristics of the companies
involved in comparable transactions and other factors that could affect the
exchange ratio premiums in such comparable transactions to which the merger is
being compared; mathematical analysis (such as determining the mean or the
median) is not in itself a meaningful method of using selected company data.

  Relative Discounted Cash Flow Analysis. Merrill Lynch, utilizing the
standalone discounted cash flow analyses (as described in this section)
calculated the implied exchange ratio, by the division of the discounted cash
flow equity value per share of Go2Net by the discounted equity value per share
of InfoSpace. Based upon this analysis, Merrill Lynch calculated the following
implied exchange ratio range:

<TABLE>
<CAPTION>
                                                                    Low    High
                                                                   ------ ------

   Implied Discounted Cash Flow
    Analysis Exchange Ratio....................................... 0.636x 2.009x

  Merrill Lynch observed that the offer exchange ratio was in the range of the
implied discounted cash flow exchange ratio.

Other items

  The summary set forth above does not purport to be a complete description of
the analyses performed by Merrill Lynch in arriving at its opinion. The
preparation of a fairness opinion is a complex process involving various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of those methods to the particular circumstances
and, therefore; such an opinion is not readily susceptible to partial analysis
or summary description, and taking portions of the analyses set out above,
without considering the analysis as a whole, would, in the view of Merrill
Lynch, create an

                                       64
<PAGE>

incomplete and misleading picture of the processes underlying the analyses
considered in rendering Merrill Lynch's opinion. In arriving at its opinion,
Merrill Lynch did not attribute any particular weight to any analysis or factor
considered by it, but rather made qualitative judgments as to the significance
and relevance of each analysis and factor. Accordingly, Merrill Lynch believes
that its analyses must be considered as a whole and that selecting portions of
its analyses and of the factors considered by it, without considering all
factors and analyses, could create a misleading view of the analyses underlying
Merrill Lynch's opinion.

  Go2Net retained Merrill Lynch based upon Merrill Lynch's experience and
expertise. Merrill Lynch is an internationally recognized investment banking
firm with substantial experience in transactions similar to the merger. Merrill
Lynch, as part of its investment banking business, is continually engaged in
the valuation of businesses and securities in connection with mergers and
acquisitions and for other purposes and has substantial experience in
transactions similar to the merger.

  Under the terms of the engagement letter between Merrill Lynch and Go2Net,
Merrill Lynch provided financial advisory services and the financial fairness
opinion in connection with the merger, and Go2Net agreed to pay Merrill Lynch a
customary fee. In addition, Go2Net has agreed to indemnify Merrill Lynch and
its affiliates, their respective directors, officers, agents and employees and
each person, if any, controlling, Merrill Lynch or any of its affiliates
against certain liabilities and expenses, including certain liabilities under
the federal securities laws, related to or arising out of Merrill Lynch's
engagement.

  In the ordinary course of its business, Merrill Lynch may actively trade in
the securities of Go2Net and InfoSpace, for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or
short position in such securities.

Interests of certain persons in the merger

  When considering the recommendations of Go2Net's board of directors, you
should be aware that the directors and officers of Go2Net have interests in the
merger and have arrangements that are different from, or are in addition to,
those of Go2Net stockholders generally. These include:

  . Directors. Three new directors, including Russell Horowitz, William Savoy
    and a third director designated by Messrs. Horowitz and Savoy and
    acceptable to InfoSpace, will be appointed to the InfoSpace board of
    directors.

  . Employment. Some executive officers of Go2Net have employment agreements
    under which they will be entitled to salary continuation and accelerated
    vesting of their outstanding options, including the Go2Net options
    assumed by InfoSpace in the merger, in the event that they are not
    offered employment by InfoSpace in a comparable position and at a
    comparable salary, or their employment is terminated by InfoSpace without
    cause during the term of their employment agreement. In addition, some
    executive officers of Go2Net will become executive officers of InfoSpace.

  . Indemnification. Go2Net directors and executive officers have customary
    rights to indemnification against losses incurred as a result of actions
    or omissions occurring prior to the effective time of the merger. In
    addition, the merger agreement provides that for a period of six years
    after the effective time, InfoSpace will maintain directors' and
    officers' liability insurance covering persons who are covered by
    Go2Net's directors' and officers' insurance policy.

  As a result, these directors, executive officers and stockholders could be
more likely to vote in favor of recommending the merger agreement and the
merger than if they did not have these interests.

Completion and effectiveness of the merger

  The merger will be completed when all of the conditions to completion of the
merger are satisfied or waived, including adoption of the merger agreement and
approval of the merger by the stockholders of

                                       65
<PAGE>

Go2Net and approval of the issuance of InfoSpace common stock in the merger by
the stockholders of InfoSpace. The merger will become effective upon the filing
of the certificate of merger with the Secretary of State of the State of
Delaware.

Structure of the merger and conversion of Go2Net common stock

  Pursuant to the merger agreement, Giants Acquisition Corp., a wholly-owned
Delaware subsidiary of InfoSpace, will merge with and into Go2Net. Immediately
following this merger, Go2Net will be a wholly-owned subsidiary of InfoSpace.

  Upon completion of the merger, each outstanding share of Go2Net common stock
will be converted into the right to receive 1.82 shares of InfoSpace common
stock. No fractional shares of InfoSpace common stock will be issued pursuant
to the merger. In lieu of the issuance of any fractional shares of InfoSpace
common stock, InfoSpace will pay a cash amount equal to the product of such
fractional share amount, after aggregating all fractional shares to which a
former holder of Go2Net common stock would be entitled, and the average closing
price of InfoSpace common stock as reported on Nasdaq for the five trading days
immediately preceding the effective time of the merger.

Exchange of Go2Net stock certificates for InfoSpace stock certificates

  When the merger is completed, InfoSpace's exchange agent will mail to Go2Net
stockholders a letter of transmittal and instructions for use in surrendering
Go2Net stock certificates in exchange for InfoSpace stock certificates. When
former Go2Net stockholders deliver their Go2Net stock certificates to the
exchange agent along with an executed letter of transmittal and any other
required documents, the Go2Net stock certificates will be canceled, and former
Go2Net stockholders will receive InfoSpace stock certificates representing the
number of full shares of InfoSpace common stock to which they are entitled
under the merger agreement. They will receive payment in cash, without
interest, in lieu of any fractional shares of InfoSpace common stock which
would have been otherwise issuable to them in the merger.

  Go2Net stockholders should not submit their Go2Net stock certificates for
exchange until they receive the transmittal instructions and a form of letter
of transmittal from the exchange agent.

No dividends

  Go2Net stockholders are not entitled to receive any dividends or other
distributions on InfoSpace common stock until the merger is completed and they
have surrendered their Go2Net stock certificates in exchange for InfoSpace
stock certificates.

  Subject to the effect of applicable laws, promptly following surrender of
Go2Net stock certificates and the issuance of the corresponding InfoSpace
certificates, Go2Net stockholders will be paid the amount of dividends or other
distributions, without interest, with a record date after the completion of the
merger which were previously paid with respect to their whole shares of
InfoSpace common stock.

  InfoSpace will only issue Go2Net stockholders an InfoSpace stock certificate
or a check in lieu of a fractional share in the name in which the surrendered
Go2Net stock certificate is registered. If Go2Net stockholders wish to have
their certificates issued in another name they must present the exchange agent
with all documents required to show and effect the unrecorded transfer of
ownership and show that they paid any applicable stock transfer taxes.

Material United States federal income tax considerations

  The following is a summary description of the material current United States
federal income tax consequences of the merger generally applicable to holders
of Go2Net common stock who, pursuant to the merger,

                                       66
<PAGE>

exchange their Go2Net common stock for InfoSpace common stock, assuming that
the merger is effected pursuant to applicable state law and as described in the
merger agreement and in this joint proxy statement/prospectus. This summary is
not a comprehensive description of all of the tax consequences that may be
relevant to Go2Net stockholders. For example, this discussion does not describe
tax consequences that arise from rules that apply to some classes of taxpayers.
This discussion also does not describe tax consequences that are generally
assumed to be known by investors.

  The following discussion is based on and subject to the Internal Revenue
Code, as amended, the regulations promulgated under the Internal Revenue Code,
and existing administrative rulings and court decisions, all as in effect on
the date of this joint proxy statement/prospectus and all of which are subject
to change, possibly with retroactive effect. This discussion also is based upon
assumptions, limitations, representations and covenants, including those
contained in certificates of InfoSpace, Giants Acquisition Corp., and Go2Net,
and may not be relied upon if any of such assumptions, limitations,
representations or covenants are, or later become, inaccurate.

  In addition, this discussion assumes that Go2Net stockholders hold their
shares of common stock as a capital asset and does not address all the United
States federal income tax consequences that may be relevant to Go2Net
stockholders in light of their particular circumstances or if Go2Net
stockholders are persons subject to special rules, such as rules applicable to:

  . banks and other financial institutions;

  . tax-exempt organizations and pension funds;

  . insurance companies;

  . dealers or traders in securities;

  . Go2Net stockholders who received their Go2Net common stock through the
    exercise of employee stock options or similar derivative securities or
    otherwise as compensation;

  . Go2Net stockholders who are subject to the alternative minimum tax
    provisions of the Internal Revenue Code;

  . Go2Net stockholders whose functional currency is not the United States
    dollar;

  . Go2Net stockholders who are not citizens or residents of the United
    States; and

  . Go2Net stockholders who held Go2Net common stock as part of a hedge,
    appreciated financial position, straddle or conversion transaction.

  This discussion does not address any consequences arising under the laws of
any state, locality or foreign jurisdiction. This discussion also does not
address the tax consequences of an exchange or conversion of options or
warrants for Go2Net common stock into options or warrants for InfoSpace common
stock.

  Completion of the merger is conditioned on the receipt by InfoSpace of an
opinion from Wilson Sonsini Goodrich & Rosati, Professional Corporation,
InfoSpace's tax counsel, and the receipt by Go2Net of an opinion from Hutchins,
Wheeler & Dittmar, A Professional Corporation, Go2Net's tax counsel, stating
that the merger will be a reorganization within the meaning of Section 368(a)
of the Internal Revenue Code. These opinions will be based upon the existing
law and the continuing truth and accuracy of the representations of Go2Net and
InfoSpace described above, and will be subject to certain assumptions and
qualifications, including the assumption that the merger will be effected
pursuant to applicable state law and otherwise completed according to the terms
of the merger agreement. The tax opinions are not binding on the Internal
Revenue Service or the courts, and there can be no assurance that the Internal
Revenue Service or the courts will not take a contrary view. No ruling from the
Internal Revenue Service has been or will be sought. Future legislative,
judicial or administrative changes or interpretations could alter or modify the
statements and conclusions set forth herein, and any such changes or
interpretations could be retroactive and could affect the tax consequences of
the merger to InfoSpace, Go2Net, or the stockholders of Go2Net.

                                       67
<PAGE>

  Counsel to InfoSpace and Go2Net have stated in writing to InfoSpace and
Go2Net, respectively, their respective views that the discussion in the five
bullet points below fairly presents the material current United States federal
income tax consequences generally applicable to the merger, based upon the
opinions of counsel described above and the foregoing assumptions:

  . no gain or loss will be recognized by InfoSpace or Go2Net as a result of
    the merger;

  . no gain or loss will be recognized by Go2Net stockholders upon the
    receipt of InfoSpace common stock solely in exchange for Go2Net common
    stock in the merger, except to the extent of cash received in lieu of a
    fractional share of InfoSpace;

  . cash payments received by Go2Net stockholders in lieu of a fractional
    share of InfoSpace common stock will result in capital gain (or loss)
    measured by the difference between the cash payment received and the
    portion of the aggregate adjusted tax basis in the shares of Go2Net
    common stock surrendered that is allocable to such fractional share. Such
    gain (or loss) will be long-term capital gain (or loss) if the holding
    period of the Go2Net common stock deemed to have been exchanged for the
    fractional share of InfoSpace common stock is more than one year at the
    effective time of the merger;

  . the aggregate tax basis of the InfoSpace common stock received by Go2Net
    stockholders in the merger will be the same as the aggregate adjusted tax
    basis of the Go2Net common stock surrendered in exchange, reduced by any
    tax basis allocable to a fractional share for which cash is received; and

  . the holding period of InfoSpace common stock received by each Go2Net
    stockholder in the merger will include the holding period of the Go2Net
    common stock surrendered in exchange.

  A successful Internal Revenue Service challenge to the "reorganization"
status of the merger would result in a Go2Net stockholder recognizing gain or
loss with respect to each share of Go2Net common stock surrendered in the
merger, equal to the difference between the Go2Net stockholder's adjusted tax
basis in such share and the fair market value, as of the effective time of the
merger, of the InfoSpace common stock received in exchange. In such event, a
Go2Net stockholder's aggregate tax basis in the InfoSpace common stock received
would equal its fair market value as of the effective time of the merger, and
the Go2Net stockholder's holding period for such stock would begin the day
after the merger.

  Tax matters are very complicated, and the tax consequences of the merger to
Go2Net stockholders will depend on their particular situation. Go2Net
stockholders are encouraged to consult their own tax advisor regarding the
specific tax consequences of the merger, including tax return reporting
requirements, the applicability of federal, state, local and foreign tax laws
and the effect of any proposed change in the tax laws. This discussion is not
intended to be a complete analysis or description of all potential tax
consequences of the merger.

Accounting treatment for the merger

  InfoSpace intends to account for the merger as a "pooling-of-interests" for
financial reporting and accounting purposes, under United States generally
accepted accounting principles. This accounting method means that after the
merger Infospace will report financial results as if Go2Net had always been
combined with InfoSpace.

Regulatory filings and approvals required to complete the merger

  This merger is subject to review by the Department of Justice and the Federal
Trade Commission to determine whether it is in compliance with applicable
antitrust laws. Under the provisions of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, the merger may not be consummated until
the specified waiting period requirements of that Act have been satisfied.
InfoSpace and Go2Net filed

                                       68
<PAGE>


notification reports, together with requests for early termination of the
waiting period, with the Department of Justice and the Federal Trade Commission
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, on
August 8, 2000. Two Go2Net affiliates also filed notification reports with the
Federal Trade Commission. On August 23, 2000, early termination of the waiting
period was granted to InfoSpace and Go2Net and both of the Go2Net affiliates.
In addition, the completion of this merger is subject to the effectiveness of
the registration statement of which this joint proxy statement/prospectus is a
part and compliance with applicable corporate laws of the State of Delaware.

Certain securities laws considerations

  The issuance of the shares of InfoSpace common stock to be issued in the
merger will be registered under the Securities Act of 1933, as amended. These
shares will be freely transferable under the Securities Act, except for
InfoSpace common stock issued to any person who is deemed to be an affiliate of
Go2Net. Persons who may be deemed to be affiliates include individuals or
entities that control, are controlled by, or are under common control with
Go2Net and may include some of Go2Net's officers and directors, as well as its
principal stockholders. Go2Net's affiliates may not sell their InfoSpace common
stock acquired in the merger except pursuant to (1) an effective registration
statement under the Securities Act covering the resale of those shares, (2) an
exemption under paragraph (d) of Rule 145 under the Securities Act or (3) any
other applicable exemption under the Securities Act.

No appraisal rights

  Under Delaware corporate law, holders of InfoSpace common stock and holders
of Go2Net common stock are not entitled to appraisal rights in connection with
the merger because, on the record date, Go2Net common stock was designated and
quoted for trading on the Nasdaq National Market and will be converted into
shares of InfoSpace common stock which at the effective time of the merger will
be listed on the Nasdaq National Market.

Listing on the Nasdaq National Market of InfoSpace common stock to be issued in
the merger

  InfoSpace has agreed to cause the shares of InfoSpace common stock to be
issued in the merger to be approved for listing on the Nasdaq National Market,
subject to official notice of issuance prior to the effective time of the
merger.

Delisting and deregistration of Go2Net common stock after the merger

  If the merger is completed, Go2Net's common stock will be delisted from the
Nasdaq National Market and will be deregistered under the Securities Exchange
Act of 1934, as amended.

Conduct of business if merger is not completed

  If the merger is not consummated, Go2Net will carry on its business in the
usual, regular and ordinary course consistent with past practice.

                              THE MERGER AGREEMENT

  This section of the joint proxy statement/prospectus describes the merger
agreement. While InfoSpace and Go2Net believe that the description covers the
material terms of the merger agreement, this summary may not contain all of the
information that is important to you. The merger agreement is attached to this
joint proxy statement/prospectus as Annex A, and InfoSpace and Go2Net urge you
to read it carefully.

General

  Following the adoption of the merger agreement and approval of the merger by
Go2Net stockholders, the approval of the share issuance by the InfoSpace
stockholders and the satisfaction or waiver of the other conditions to the
merger, the transitory subsidiary, a wholly-owned subsidiary of InfoSpace, will
merge with and into Go2Net. Go2Net will survive the merger as a wholly-owned
subsidiary of InfoSpace. If all conditions to the merger are satisfied or
waived, the merger will become effective at the time of the filing by Go2Net of
a duly executed certificate of merger with the Secretary of State of the State
of Delaware.

The exchange ratio and treatment of Go2Net preferred stock and common stock

  Immediately prior to the effective time of the merger, each issued and
outstanding share of Go2Net preferred stock will be converted into 30.2526
shares of Go2Net common stock. At the effective time of the merger, each issued
and outstanding share of Go2Net common stock will be converted into the right
to receive 1.82 shares of InfoSpace common stock. However, any shares owned by
Go2Net or any of its wholly-owned subsidiaries will be cancelled without
conversion. InfoSpace will adjust the exchange ratio to reflect any
reclassification, stock split, stock dividend, reorganization or other similar
change with respect to InfoSpace common stock or Go2Net common stock occurring
before the effective time of the merger.

  Based on the exchange ratio of 1.82, and based on the number of shares of
Go2Net common stock, preferred stock and vested options to purchase Go2Net
common stock outstanding as of August 28, 2000, a total of approximately
80,346,246 shares of InfoSpace common stock and options to purchase InfoSpace
common stock will be issued or granted in the merger.

Treatment of restricted stock of Go2Net

  Any shares of Go2Net capital stock outstanding at the effective time of the
merger which are subject to a repurchase option, risk of forfeiture or other
condition under any restricted stock purchase agreement or other arrangements
will be converted into unvested shares of InfoSpace common stock based on the
exchange ratio and will remain subject to the same terms, restrictions and
vesting schedules as were applicable prior to the effective time of the merger.
InfoSpace will assume any rights Go2Net held prior to the effective time of the
merger to repurchase these unvested shares.

Treatment of Go2Net stock options

  At the effective time of the merger, InfoSpace will assume each outstanding
option, whether vested or unvested, to purchase shares of Go2Net common stock
and convert them into options to purchase InfoSpace common stock subject to the
same terms and conditions as were applicable prior to the effective time of the
merger, including, without limitation, any repurchase rights or vesting
provisions. The number of shares of InfoSpace common stock issuable upon the
exercise of these stock options will be adjusted based on the exchange ratio.
Any fractional share of InfoSpace common stock resulting from such adjustment
will be rounded down to the nearest whole number. The exercise price per share
of InfoSpace common stock issuable under each Go2Net option will equal the
exercise price per share of the Go2Net common stock purchasable under the
Go2Net option divided by the exchange ratio. The exercise price will be rounded
up to the nearest whole cent.

                                       70
<PAGE>

  InfoSpace will reserve for issuance a sufficient number of shares of its
common stock for delivery upon a Go2Net optionholder's exercise of his or her
option. InfoSpace will file a registration statement on Form S-8 with respect
to the assumed Go2Net stock options.

  As of the effective time of the merger, Go2Net's Employee Stock Purchase Plan
will be terminated, and participants of that plan will become participants in
InfoSpace's Employee Stock Purchase Plan.

Exchange of certificates

  Exchange Agent; Exchange Procedures; No Further Ownership Rights. After the
effective time of the merger, InfoSpace's exchange agent will mail to each
record holder of Go2Net common stock a letter of transmittal and instructions
for surrendering their certificates. Only those holders who properly surrender
their certificates in accordance with the instructions will receive
certificates representing InfoSpace common stock, cash in lieu of any
fractional InfoSpace common stock and any dividends or distributions to which
they are entitled. The surrendered certificates representing shares of Go2Net
common stock will be cancelled. After the effective time of the merger, each
certificate representing shares of Go2Net common stock that have not been
surrendered will only represent (1) the number of whole shares of common stock
of InfoSpace into which such shares have been converted, (2) the right to
receive cash in lieu of any fractional share of InfoSpace common stock and (3)
any dividends or distributions that may be applicable. Following the effective
time of the merger, Go2Net will not register any transfers of Go2Net common
stock on its stock transfer books.

  No Fractional Shares. InfoSpace will not issue any fractional shares of
common stock in the merger. Instead, each holder of shares of Go2Net common
stock exchanged in the merger who would otherwise be entitled to receive a
fraction of a share of common stock of InfoSpace will receive cash, without
interest, equal to such fraction multiplied by the average closing price per
share of InfoSpace common stock on the Nasdaq National Market for the five
trading days immediately preceding the effective time of the merger.

  Distributions With Respect to Unexchanged Shares. After the effective date of
the merger, dividends or other distributions declared or made after the closing
of the merger with respect to InfoSpace common stock will be paid to the holder
of any unsurrendered Go2Net certificate when the holder surrenders its Go2Net
certificate in accordance with the letter of transmittal.

  Lost Certificates. If any Go2Net common stock certificate is lost, stolen or
destroyed, a Go2Net stockholder must provide an appropriate affidavit
certifying that fact. InfoSpace may require a Go2Net stockholder to deliver a
bond as indemnity against any claim that may be made against InfoSpace with
respect to any lost, stolen or destroyed certificate.

  Holders of Go2Net common stock should not send in their certificates until
they receive a letter of transmittal from the exchange agent.

Conduct of business before completion of the merger

the merger or termination of the merger agreement or unless the other consents
in writing, each company will use its commercially reasonable efforts
consistent with past practices and policies to:

  . preserve intact its present business organization;

                                       72
<PAGE>

  . keep available the services of its present officers and employees; and

  . preserve its relationships with customers, suppliers, distributors,
    licensors, licensees, and others with which it has business dealings.

  . revaluation of assets or changing of accounting policies and procedures;

  . actions which could be expected to impact treatment of the merger as a
    "reorganization" under the Internal Revenue Code; and

  . making of tax elections.

  The agreements related to the conduct of Go2Net's and InfoSpace's businesses
in the merger agreement are complicated and not easily summarized. You are
urged to carefully read the sections of the merger agreement entitled "Conduct
of Business by Company," relating to Go2Net and "Conduct of Business By
Parent," relating to InfoSpace.

No solicitation by Go2Net

  Go2Net further agreed to cease, as of the date of the merger agreement, any
and all existing activities, discussions or negotiations with any parties
conducted prior to that date with respect to any Acquisition Proposal (as
defined below).

  Until the merger is completed or the merger agreement is terminated, Go2Net
and its subsidiaries agreed not to directly or indirectly take any of the
following actions:

  . solicit, initiate, encourage or induce the making, submission or
    announcement of any Acquisition Proposal;

  . except as provided below with respect to an unsolicited bona fide
    proposal, furnish to any person any non-public information with respect
    to any Acquisition Proposal;

  . 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
    Acquisition Proposal;

                                       73
<PAGE>

  . except as provided below with respect to an unsolicited bona fide
    proposal, engage in discussions or negotiations with any person with
    respect to any Acquisition Proposal;

  . subject to limited exceptions, approve, endorse or recommend any
    Acquisition Proposal; or

  . enter into any contract relating to any Acquisition Transaction.

  Go2Net's board of directors may, without breaching the merger agreement,
respond to an unsolicited, bona fide written Acquisition Proposal by discussing
the proposal with the party making the proposal, furnishing information to the
party making the proposal, recommending a Superior Offer to Go2Net's
stockholders or terminating the merger agreement with InfoSpace in order to
immediately thereafter enter into a Superior Offer (as defined below), if
certain of the following conditions are met:

  . Go2Net's board determines in good faith, after consulting with its
    outside legal counsel, that this action is necessary to comply with its
    fiduciary obligations under applicable laws;

  . Go2Net receives from such person an executed confidentiality agreement;

  . Go2Net gives prior written notice to InfoSpace of discussions or
    negotiations with, or furnishing of information to, the party making the
    proposal;

  . when furnishing nonpublic information to the party making the proposal,
    Go2Net contemporaneously furnishes the same information to InfoSpace, to
    the extent it has not already been received by InfoSpace;

  . neither Go2Net nor any representative of Go2Net or its subsidiaries shall
    have violated any of the non-solicitation provisions contained in the
    merger agreement; and

  . in the case of a termination of the merger agreement or a change of
    recommendation, Go2Net's board concludes in good faith that the proposal
    constitutes a Superior Offer.

  For purposes of the foregoing, any action by any officer, director, affiliate
or employee of Go2Net or any investment banker, attorney or other advisor or
representative of Go2Net is deemed to be an action by Go2Net.

  An "Acquisition Proposal" is any offer, inquiry or proposal relating to any
Acquisition Transaction, other than an offer, inquiry or proposal from
InfoSpace.

  An "Acquisition Transaction" is any transaction or series of related
transactions, other than the InfoSpace/Go2Net merger, involving any of the
following:

  . the acquisition or purchase from Go2Net of more than a 15% interest in
    the total outstanding voting securities of Go2Net or any of its
    subsidiaries;

  . any tender offer or exchange offer that if consummated would result in
    any person or group beneficially owning 15% or more of the total
    outstanding voting securities of Go2Net or any of its subsidiaries;

  . any merger, consolidation, business combination or similar transaction
    involving Go2Net pursuant to which the stockholders of Go2Net immediately
    preceding such transaction hold less than 85% of the equity interests in
    the surviving or resulting entity;

  . any sale, lease outside the ordinary course of business, exchange,
    transfer, license outside the ordinary course of business, acquisition or
    disposition of more than 15% of the assets of Go2Net; or

  . any liquidation or dissolution of Go2Net.

  A "Superior Offer" is an unsolicited, bona fide written offer made by a third
party to consummate any of the following transactions, and which Go2Net's board
of directors determines in its reasonable judgment

                                       74
<PAGE>

(based on written advice of its nationally recognized financial advisor) is
more favorable to its stockholders from a financial point of view than the
merger with InfoSpace:

  . a merger, consolidation, business combination, recapitalization,
    liquidation, dissolution or similar transaction involving Go2Net in which
    the stockholders Go2Net just prior to the transaction would hold less
    than 51% of the equity interest in the resulting entity after the
    transaction;

  . a sale or disposition by Go2Net of assets, excluding inventory and used
    equipment sold in the ordinary course of business, which comprise more
    than 51% of the market value of Go2Net's business just prior to the sale;
    or

  . the acquisition of beneficial ownership of more than 51% of the voting
    power of Go2Net's outstanding stock.

  Go2Net has agreed to promptly inform InfoSpace of any request for information
that Go2Net reasonably believes would lead to an Acquisition Proposal, or of
any Acquisition Proposal, or any inquiry with respect to or which Go2Net
reasonably believes would lead to any Acquisition Proposal, the material terms
and conditions of such request, Acquisition Proposal or inquiry, and the
identity of the person or group making any such request, Acquisition Proposal
or inquiry. Go2Net further agreed to keep InfoSpace informed in all material
respects of the status and details, including material amendments or proposed
amendments, of any such request, Acquisition Proposal or inquiry, and to
provide InfoSpace with advance notice of any meeting of the Go2Net board of
directors at which the board of directors is reasonably expected to consider an
Acquisition Proposal or recommend a Superior Proposal to Go2Net's stockholders.

Go2Net stockholder's meeting

  Regardless of whether there has been a Superior Offer, unless the merger
agreement has been terminated, Go2Net is obligated to hold and convene the
Go2Net special meeting of stockholders for purposes of voting for adoption of
the merger agreement and approval of the merger. Go2Net's board of directors
will recommend that Go2Net's stockholders vote in favor of adoption of the
merger agreement and approval of the merger; provided, however, that the board
can withhold, withdraw, amend or modify its recommendation if:

  . a Superior Offer is made to Go2Net;

  . neither Go2Net nor any of its representatives have violated the non-
    solicitation provisions and thereby breached the merger agreement;

  . Go2Net's board determines in good faith, after consulting with its
    outside legal counsel, that this action is necessary to comply with its
    fiduciary obligations under applicable laws; and

  . Go2Net gives InfoSpace at least forty-eight (48) hours notice and the
    opportunity to meet with Go2Net and its legal counsel.

InfoSpace stockholder's meeting

  Unless the merger agreement is terminated, InfoSpace is obligated under the
merger agreement to hold and convene the InfoSpace special meeting of
stockholders for purposes of voting on the issuance of shares of InfoSpace
common stock in the merger. InfoSpace's board of directors will recommend that
InfoSpace's stockholders vote in favor of the issuance of InfoSpace's shares in
connection with the merger.

Employee benefits matters

  Individuals who continue to be employed by Go2Net after the merger is
completed who become participants or are subject to InfoSpace's employee
benefit plans will, subject to certain qualifications, receive credit for
length of service with Go2Net prior to the merger for eligibility and vesting
purposes.

  . by InfoSpace or Go2Net, if the merger is not completed before January 31,
    2001 except that this right to terminate the merger agreement is not

    or before January 31, 2001 and this action or failure to act constitutes
    a material breach of the merger agreement;

  . by InfoSpace or Go2Net, if there is any final and nonappealable action of
    a court or governmental authority having jurisdiction over either
    InfoSpace or Go2Net permanently restraining, enjoining or prohibiting the
    completion of the merger;

  . by InfoSpace or Go2Net, if the stockholders of Go2Net fail to adopt the

    meeting, or if the stockholders of InfoSpace fail to approve the share
    issuance at an InfoSpace stockholders' meeting, except that this right to

    party's action or failure to act which constitutes a breach of the merger
    agreement;

  . by Go2Net, upon InfoSpace's breach of any covenant or agreement in the
    merger agreement, or if any of InfoSpace's representations or warranties
    are or become untrue so that the corresponding condition to completion of

    curable by InfoSpace, and InfoSpace exercises commercially reasonable
    efforts to cure the breach, Go2Net may not terminate the merger agreement
    for 30 days after delivery of written notice from Go2Net to InfoSpace of
    the breach;

  . by InfoSpace, upon Go2Net's breach of any covenant or agreement in the

    by Go2Net and Go2Net exercises commercially reasonable efforts to cure
    the breach, InfoSpace may not terminate the merger agreement for 30 days
    after delivery of written notice from InfoSpace to Go2Net of the breach;

  . by InfoSpace if any of the following shall have occurred:

   --Go2Net's board of directors withdraws, modifies or changes its
     recommendation of the merger agreement or the merger in a manner
     adverse to InfoSpace or its stockholders;

   --Go2Net's board of directors approves or recommends any Acquisition

     Acquisition Proposal;

                                       77
<PAGE>

   --Go2Net breaches any of the non-solicitation provisions of the merger
     agreement; or

   --an Acquisition Proposal is announced or becomes publicly known to
     Go2Net's board of directors, or a tender offer or exchange offer
     relating to at least 15% of Go2Net's outstanding capital stock is
     commenced and, in either case, Go2Net's board of directors fails to
     recommend against that proposal or fails to reconfirm its approval and
     recommendation of the merger agreement and the merger, within ten
     business days; or

  . by Go2Net before the vote of its stockholders on the merger agreement, if
    after receiving a Superior Offer and in the absence of any breach of the
    non-solicitation provisions of the merger agreement, the Go2Net board of
    directors determines in good faith, after consulting with its outside
    legal counsel, that termination of the merger agreement is necessary to
    comply with its fiduciary duties under applicable law. Go2Net may not
    terminate the merger agreement, however, until two business days after
    notifying InfoSpace of the Go2Net board's determination and until Go2Net
    has paid InfoSpace the termination fee set forth in the merger agreement.

Payment of termination fee by Go2Net

  Go2Net will pay InfoSpace a termination fee of $120 million if any of the
following conditions occur:

  . InfoSpace terminates the merger agreement because of any of the
    following:

     Proposal;

   --Go2Net breaches any of the non-solicitation provisions of the merger
     agreement;

   --an Acquisition Proposal is announced or becomes publicly known to
     Go2Net's board of directors, or a tender offer or exchange offer
     relating to at least 15% of Go2Net's outstanding capital stock is
     commenced and, in either case, Go2Net's board of directors fails to
     recommend against that proposal or fails to reconfirm its approval and
     recommendation of the merger agreement and the merger, within ten
     business days; or

  . Go2Net terminates the merger agreement prior to the vote of its
    stockholders, because it received a Superior Offer which the Go2Net board
    of directors determined in good faith, after consulting with its outside
    legal counsel, necessitated terminating the merger agreement in order to
    comply with its fiduciary duties under applicable law.

  Further, Go2Net will pay to InfoSpace the termination fee of $120 million if
the merger agreement is terminated because the merger is not consummated by
January 31, 2001 or Go2Net's stockholders do not approve the merger agreement
and:

  . prior to termination a third party announces an Acquisition Proposal; and

  . within twelve months following the termination of the merger agreement
    any of the following is consummated or Go2Net enters into an agreement or
    binding letter of intent providing for any of the following transactions
    (which transaction is subsequently consummated):

   --a merger, consolidation, business combination, recapitalization,
     liquidation, dissolution or similar transaction involving Go2Net
     pursuant to which stockholders of Go2Net immediately prior to the
     transaction hold less than 60% of the aggregate equity interests of the
     resulting entity;

   --a sale or disposition by Go2Net of assets representing greater than 60%
     of the market value of its business immediately before that sale; or

   --the acquisition of beneficial ownership of greater than 50% of the
     voting power of Go2Net's outstanding capital stock.

                                       78
<PAGE>

  Additionally, Go2Net granted InfoSpace an option to purchase such number of
shares equal to 19.9% of Go2Net's common stock outstanding as of July 26, 2000
for an exercise price of $84.28 per share. This option is exercisable by
InfoSpace upon the occurrence of any event which causes the termination fee to
become payable by Go2Net to InfoSpace under the merger agreement. For more
information regarding the option, you should refer to the "Option Agreement"
included as Exhibit B to the merger agreement and see page 81 of this joint
proxy statement/prospectus.

Operations after the merger

  Following the merger, it is expected that Go2Net will continue its operations
as a wholly-owned subsidiary of InfoSpace. The stockholders of Go2Net will
become stockholders of InfoSpace, and their rights as stockholders will be
governed by the InfoSpace certificate of incorporation and bylaws, as currently
in effect, and the laws of Delaware. See "Comparison of Stockholder Rights and
Corporate Governance Matters" on page 142 of this joint proxy
statement/prospectus.

Extension, waiver and amendment of the merger agreement

  InfoSpace and Go2Net may amend the merger agreement before completion of the
merger by mutual written consent. In addition, either InfoSpace or Go2Net may
extend the other's time for the performance of any of the obligations or other
acts under the merger agreement, waive any inaccuracies in the other's
representations and warranties and waive compliance by the other with any of
the agreements or conditions contained in the merger agreement.

officers, directors and stockholders agreed not to transfer or otherwise reduce
their risk relative to any shares of InfoSpace common stock during the period
from the date 30 days prior to the merger effective date until InfoSpace
publicly announces financial results covering at least 30 days of combined
operations of InfoSpace and Go2Net. In accordance with the affiliate
agreements, InfoSpace will be entitled to issue stop transfer instructions to
the transfer agent for the InfoSpace common stock held by these directors,
officers and significant stockholders. The form of InfoSpace affiliate
agreement is attached as Exhibit C-2 to the merger agreement which is attached
to this joint proxy statement/prospectus as Annex A, and you are urged to read
it in its entirety.

Go2Net Affiliate Agreements

  Each member of the Go2Net board of directors, each executive officer of
Go2Net and certain significant stockholders of Go2Net have each executed an
affiliate agreement. Under the affiliate agreements, these Go2Net officers,
directors and stockholders agreed not to transfer or otherwise reduce their
risk relative to any shares of Go2Net common stock during the period from the
date 30 days prior to the merger effective date until InfoSpace publicly
announces financial results covering at least 30 days of combined operations of
InfoSpace and Go2Net. Further, these persons have also acknowledged the resale
restrictions imposed by Rule 145 under the Securities Act on shares of
InfoSpace common stock to be received by them in the merger. In accordance with
the affiliate agreements, InfoSpace will be entitled to place appropriate
legends on these Go2Net stockholders' certificates evidencing any InfoSpace
common stock to be received by them and to issue stop transfer instructions to
the transfer agent for the InfoSpace common stock held by them. The form of
Go2Net affiliate agreement is attached as Exhibit C-1 to the merger agreement
which is attached to this joint proxy statement/prospectus as Annex A, and you

Option Agreement

  As a condition to InfoSpace's willingness to enter into the merger agreement,
Go2Net granted to InfoSpace an irrevocable option to acquire up to 6,239,917
shares of common stock, which was equal to 19.9% of Go2Net's outstanding shares
as of July 26, 2000. The exercise price payable for these shares is $84.28 per
share, payable in cash. The number of shares issuable upon exercise of the
option and the exercise price of the option are subject to adjustment to
prevent dilution. The form of option agreement is attached as Exhibit B to the
merger agreement, which is attached to this proxy statement/prospectus as Annex
A, and you are urged to read it in its entirety.

  The option is intended to increase the likelihood that the merger will be
completed. Some of the aspects of the stock option agreement may have the
effect of discouraging persons who might now or at any time be interested in
acquiring all or a significant interest in Go2Net or its assets before
completion of the merger.

                                       81
<PAGE>

    Go2Net's stockholders other than the transaction contemplated by the
    merger agreement;

  --Go2Net enters into any agreement or contract accepting any Acquisition
    Proposal other than the transaction contemplated by the merger
    agreement;

  --a tender or exchange offer relating to at least 15% of Go2Net's
    outstanding stock is commenced by a third party, and Go2Net fails to
    recommend rejection of such offer within 10 business days; or

  --an acquisition proposal is publicly announced and Go2Net fails to
    reaffirm its recommendation within ten days of InfoSpace's request;

  . the termination of the merger agreement by Go2Net after it receives a
    Superior Offer;

  . the termination of the merger agreement by InfoSpace if Go2Net fails to
    comply with the provisions in the merger agreement regarding
    nonsolicitation; or

  . the termination of the merger agreement because the required approval of
    the Go2Net stockholders has not been obtained and prior to this
    transaction a bona fide acquisition proposal was announced or otherwise
    became publicly known and within 12 months after such termination, Go2Net
    enters into a binding letter of intent or definitive acquisition
    agreement providing for an acquisition of Go2Net or an acquisition of
    Go2Net is consummated, other than the acquisition contemplated by the
    merger agreement.

  Termination. The option will terminate and cease to be exercisable upon the
earliest of any of the following:

  . the completion of the merger;

  . 12 months after termination of the merger agreement based on a failure of
    the merger to be consummated by January 31, 2001 or the failure to obtain
    the required approval of Go2Net stockholders if no event causing the
    termination fee to become payable has occurred;

  . 12 months after termination of the merger agreement based on Go2Net's:

   --board of directors' withdrawing, modifying or changing its
     recommendation regarding the merger adverse to InfoSpace;

   --board of directors' recommendation of another Acquisition Proposal;

   --failure to comply with the nonsolicitation provisions;

                                       82
<PAGE>

   --board of directors' failure to recommend against acceptance and
     reconfirm its approval of the merger agreement and related transactions
     after the public announcement of a bona fide Acquisition Proposal or
     other public knowledge of such an acquisition;

   --entering into any agreement or contract accepting any acquisition
     proposal other than the transaction contemplated by the merger
     agreement;

     to at least 15% of Go2Net's outstanding stock by a third party within
     10 business days; or

   --termination of the merger agreement after receiving a Superior Offer;

  . 12 months after payment of the termination fee in connection with a
    termination of the merger agreement based on a failure of the merger to
    have been consummated by January 31, 2001 or failure to obtain the
    required approval of Go2Net's stockholders; and

  . the date on which the merger agreement is otherwise terminated.

  Repurchase at the Option of InfoSpace. During the period when the option is
exercisable, InfoSpace may require Go2Net to repurchase from InfoSpace the
unexercised portion of the option at a price, referred to as the Market/Tender
Offer Price, equal to the difference between: (a) the higher of (i) the highest
price per share offered pursuant to any acquisition proposal and (ii) the
highest closing sale price of Go2Net common stock on the Nasdaq National Market
for the 20 preceding trading days; and (b) the option exercise price. InfoSpace
can also require Go2Net to repurchase from InfoSpace shares that InfoSpace
purchased upon exercise of the option at a repurchase price equal to the
exercise price plus the difference between the Market/Tender Offer Price and
the option exercise price multiplied by the number of shares purchased. In no
event will Go2Net be required to pay in excess of an aggregate of $120,000,000
minus the amount of the total termination fee paid by Go2Net to InfoSpace
pursuant to the merger agreement.

  Economic Benefit to InfoSpace is Limited. The option agreement limits the
maximum profit to InfoSpace, including the amount, if any, paid to InfoSpace as
a termination fee under the merger agreement, which may be received by
InfoSpace to $120 million.

  Registration Rights. The option agreement grants registration rights to
InfoSpace with respect to the shares of Go2Net common stock represented by the
option, including the right to demand that Go2Net register all or part of such
shares with the Securities and Exchange Commission, provided that InfoSpace
will only be able to make two such demands, and has the right to register all
or part of such shares if Go2Net otherwise register effects a registration for
its own account.

                               INFOSPACE BUSINESS

  In this section, InfoSpace Business, references to "we," "us," "our" and
"ours" refer to InfoSpace and its consolidated subsidiaries.

Overview

  InfoSpace is an international information infrastructure services company.
InfoSpace provides commerce, information and communication infrastructure
services for wireless devices, merchants and Web sites. Our affiliates utilize
and distribute these services through a network of wireless and other non-PC
devices including PCs, cellular phones, pagers, screen telephones, television
set-top boxes, online kiosks, and personal digital assistants as well as PC-
based Web sites. We have relationships with AT&T Wireless, Verizon Wireless,
Vodafone AirTouch, ALLTEL, SBC, VoiceStream, Qwest, Intel, Ericsson, Nokia,
Mitsui and Acer America. InfoSpace's affiliate network also consists of more
than 3,100 Web sites that include America Online, Microsoft's MSN, Disney's GO
Network, NBC's Snap, Lycos, Go2Net and ABC LocalNet, among others.

Our Infrastructure Services

  We have developed a scalable, flexible technology platform that enables us to
deliver a broad, integrated suite of services to Web sites, merchants and
wireless carriers. All of our consumer, merchant and wireless services utilize
the same core technology platform within the same operational infrastructure.
Our consumer services are designed for the end user and are distributed through
wireless devices and Web sites. These services include four main components:
(1) unified communication services, including device-independent email and
instant messaging; (2) information services, such as integrated directory,
news, and lifestyle information; (3) community services, including the "sticky"
services such as online address books and calendars; and (4) the ability to
offer collaboration services, including real-time document sharing. We target
merchant services to local merchants (including service-based merchants such as
restaurants and dry cleaners) and distribute these services through our
relationships with the regional bell operating companies (RBOCs), merchant
banks and other financial institutions and other local media networks,
including newspapers and television and radio stations. These services include
commerce services such as online storebuilding and technology that promotes
merchant services. We target wireless services to mobile users, whether on a
cellular phone, personal digital assistant (or PDA), pager or other non-PC
device, and distribute these services through our relationships with wireless
carriers and device manufacturers. These services include the ability to
conduct secure commerce using single-click buying, integrated information
services such as real-time stock quotes and traffic reports, and services that
manage users' lives, including online address books and calendars.

  We design our infrastructure services to be highly flexible and customizable,
enabling affiliates to select from among our broad range of consumer, merchant
and wireless services. One of our principal strengths is our internally
developed technology, which enables us to easily and rapidly add new affiliates
and distribution partners by employing a distributed, scalable architecture
adapted specifically to our Internet-based infrastructure services. We help our
affiliates and distribution partners build and maintain their brands by
delivering our consumer, merchant and wireless services with the look and feel
and navigation features specific to each affiliate's delivery platform and
format, including the growing number of emerging wireless devices.

  We have built a large distribution network through our direct sales force and
through reseller channels. Our reseller channels are based on distribution
agreements with online advertising networks, such as DoubleClick and Flycast,
who offer both our consumer and merchant services to their network of thousands
of Web sites; reseller agreements with RBOCs, including BellSouth, SBC, Verizon
and Qwest; merchant banks such as American Express and Bank of America; and
other local media networks who provide our services to local merchants.

                                       84
<PAGE>

  A key component of our strategy is expanding our operations into
international markets. Through a joint venture, we began providing content
services in the United Kingdom in the third quarter of 1998. In March 1999 we
began providing infrastructure services to Canadian affiliates through a
Canadian subsidiary. In addition, with our acquisition of Saraide, we have
begun to expand our wireless services into Europe, Japan and Canada. We expect
to launch our subsidiary in India to provide comprehensive, localized consumer,
merchant and wireless services to the India market. We have also entered into
agreements to expand our services into Brazil, China and Australia and are
currently investigating other international opportunities.

Consumer Services

 Information Services

  We provide information of broad appeal to users of wireless devices and PCs,
including maps, directories, financial data, traffic reports, sports, news and
entertainment. In most cases, we receive regular data feeds from our content
providers and store the content on our Web servers in order to maintain its
reliability and increase its accessibility. In other cases, our proprietary
technology allows Web users to transparently access content that is stored
directly on the content provider's system. In either case, our technology
enables us to integrate heterogeneous content from multiple sources and make it
appear as if it comes from one source, which is then delivered to our
affiliates. Our technology pulls the information dynamically into a Web page or
device output display that maintains the look and feel and navigation features
of each affiliate's Web site or wireless device.

  We have acquired rights to third-party content pursuant to more than 85
license agreements, typically having terms of one to five years. The license
agreements require the content provider to update content on a regular basis,
the frequency of which varies depending on the type of content. In certain
arrangements, the content provider pays us a carriage fee for syndication of
its content to our network of affiliates. In other instances, we share with the
content provider advertising revenues attributable to end-user access of the
provider's content. For certain of our content, including our core directory
and map content, we pay a one-time or periodic fee or fee per content query to
the content provider. We typically enter into nonexclusive arrangements with
our content providers. However, in certain instances we have entered into
exclusive relationships, which may limit our ability to enter into additional
content agreements.

  For our directory services, we integrate our yellow pages and white pages
information with each other and utilize yellow pages category headings in
combination with a natural word search feature to provide a user-friendly
interface and navigation vehicle within our directory services. We also
typically include maps and directions for addresses included in our directory
services. We further enhance the relevance and accuracy of responses to user
queries by employing a radial search feature to our directory services, which
allows users to specify the geographic scope within a radial distance of a
specific address, rather than more conventional methods of searching by zip
code or city and county.

  In addition to our directory services, we distribute other valuable
information of broad appeal with everyday significance, such as classifieds,
news, travel and city guide information, real-time stock quotes and financial
information, Web directories and entertainment.

  Our future success will depend on our ability to continue to integrate and
distribute information services of broad appeal. Our ability to maintain our
relationships with content providers and to build new relationships with
additional content providers is critical to the success of our business.

 Community and Communications Services

  We offer an extensive and integrated platform of consumer services that
includes community services and communication services.

                                       85
<PAGE>

  Community-building services that we offer our affiliates include the "sticky"
services that are designed to keep a user on an affiliates' site. These include
personalized Web-based address books and calendars, personal home pages, online
chat and message boards.

  We also offer unified communication services including device-independent
email and instant messaging. We integrate these services into the community-
building services we offer, making it easy for users to send email and instant
messages directly from their address book from any device and also view "buddy
lists" on any device.

 Our Affiliate Network

  We offer our infrastructure services to wireless device manufacturers such as
Nokia and Ericcson, wireless carriers such as AT&T Wireless, Verizon Wireless,
Voicestream and USWest (now part of Qwest) and wireless service providers such
as AvantGo. Our PC-based affiliate network now consists of over 3,100 portals
and affinity sites, including 4 of the top 5 most trafficked sites, according
to Media Metrix. In addition, we believe our affiliate network now reaches over
90% of all Internet users based on data as of March 31, 2000, provided by Media
Metrix.

  Our consumer services revenue is derived from advertising, licensing fees and
guaranteed transaction fees in lieu of revenue share.

Merchant Services

  Our merchant services give merchants the ability to create, promote, sell and
distribute their products and services across multiple channels through our
broad distribution network. We have reseller agreements with RBOCs, including
BellSouth, SBC, Bell Atlantic and Qwest, merchant banks and other local media
networks, such as newspapers, who provide our services to local merchants
worldwide.

  Based on a broad platform of technology, we can deliver a broad array of
merchant services such as:

  . the online delivery to any device of promotions that can be used online
    and offline;

  . single-click buying from any Web site directly from a wireless device;

  . Page Express, which enables local merchants to create a Web presence;

  . StoreBuilder, which enables merchants to build online stores;

  . ActivePromotion, which enables merchants to create targeted product
    promotions and distribute them across our network; and

  . ActiveShopper, which provides an open marketplace where consumers can
    find, research and purchase products from our merchant network.

  Due to a recent acquisition, we can now integrate online promotion
technologies with an offline merchant's existing credit card processing
infrastructure, bridging the gap between the online and offline worlds. Our
enhanced commerce infrastructure will be designed to target and deliver online
promotions to consumers on their wireless devices or while they are looking for
goods and services on Web sites. To take advantage of the promotion, the user
can purchase the goods online, through a catalog or at a physical retail store.

  Through our acquisition of Millet Software (PrivacyBank.com), we believe we
will be able to provide a server-based technology that enables wireless
Internet devices to become commerce-enabled devices by giving mobile users the
ability to press one key to make on-the-spot purchases from virtually any Web
site. This is possible through a patent-pending secure technology that provides
an automated process for completing payment forms, eliminating the need to
continually enter in payment or shipping information, register at sites or
enter any specific passwords.

                                       86
<PAGE>

  Buyers can also purchase multiple products from multiple merchants, using
our shopping cart that provides the convenience of single-click purchasing.

  Currently, over 600,000 merchants use our merchant service offerings.

Wireless Services

  Our wireless services are comprised of an integrated suite of wireless
portal services that provide mobile users with relevant information services,
such as real-time stock quotes and traffic reports, the ability to conduct
secure commerce transactions from a wireless device, including single-click
buying, communication services such as device-independent instant messaging
and email, personalization capabilities and location-based services that
enable users to search for location-based information, such as the restaurant
closest to the mobile user's current location.

  As a result of our acquisition of Saraide, we have begun to expand our
wireless services into Europe, Japan and Canada.

  Our wireless services are distributed through the following wireless
carriers, device manufacturers and software providers.


  Wireless Carriers                          AT&T Wireless, Verizon Wireless,
                                             Vodafone AirTouch, ALLTEL, SBC,
                                             VoiceStream, Qwest

  Wireless Software Application              AvantGo, JP Systems, WolfeTech,
   Developers                                Phone.com

  Wireless Device Manufacturers              Nokia and Ericcson

  Pagers                                     Motorola

  Web Appliances                             Intel


  Our platform of wireless services includes:

  . Form-filling instant buying technology, which allows mobile users to
    press a single key to conduct transactions from virtually any Web site.

  . Promotions technology, which allows mobile users to find and receive
    real-time promotions on wireless devices from retailers and service-based
    merchants, such as dry cleaners and restaurants, that can be used online
    and offline. To take advantage of the promotion, the user can either
    purchase the goods online, go to the retail store or simply utilize the
    service. Promotions are seamlessly matched and automatically credited to
    the user's credit card statement through secure back-end transaction
    processing.

  . Location-based directory services, that enable mobile users to search for
    information, such as finding an Italian restaurant closest to where they
    are when they conduct the search.

  . Secure wireless commerce through a collaboration with VeriSign to deliver
    a broad range of services aimed at facilitating trusted and secure
    commerce applications across the wired and wireless Internet. By
    incorporating VeriSign's strengths in Internet authentication, validation
    and payment services, we will be able to offer a broad range of secure
    services tailored to the wireless market.

  Our wireless Internet services are device-independent and provide a platform
which enables our wireless carriers to support HDML and SMTP and a variety of
emerging protocols such as WAP, VXML and PQA's for Palm VII. Our services are
compatible with a variety of gateway technologies including WAP gateways from
Nokia, Phone.com and Ericsson.

  Our wireless services are private-labeled for each carrier, preserving the
brand of the carrier and their relationship with their customer and helping to
create a barrier to switch. Revenues are primarily generated from the carrier
and include licensing fees, per subscriber/per month fees in the United States
and per

                                      87
<PAGE>

query/per message fees in Europe. In addition, we receive commerce revenue for
the transactions completed on the wireless devices.

International Expansion

  We intend to capitalize on what we perceive to be a significant opportunity
for our services in international markets. We currently maintain offices in the
United States, Canada, the Netherlands, France, the United Kingdom, Australia
and Brazil. Our wholly-owned subsidiary, InfoSpaceCanada.com, was formed in
early 1999 and has affiliate relationships with canada.com, a leading Canadian
Web site and search engine, as well as AOL Canada, MSN Canada and Sprint
Canada. InfoSpace.com India was formed as a result of our December 1999
acquisition of privately-held Zephyr Software and its wholly-owned subsidiary,
Zephyr Software (India) Private Limited.

  In 1998, we entered into a joint venture with TDLI.com Limited, a subsidiary
of Thomson Directories Limited, to form TDL InfoSpace to replicate our
infrastructure services in Europe. TDL InfoSpace has targeted the United
Kingdom as its first market, and content services were launched in the third
quarter of 1998. Under the license agreement between Thomson and TDL InfoSpace,
Thomson licenses its U.K. directory information database to TDL InfoSpace.
Under the Web site services agreement between Thomson and TDL InfoSpace,
Thomson also sells Internet yellow pages advertising for the joint venture
through its local sales force. Under our license agreement with TDL InfoSpace,
we license our technology and provide hosting services to TDL InfoSpace. On
August 31, 2000, we acquired all of the issued and outstanding capital stock of
TDLI.com Limited. This acquisition gave us 100% control of TDL InfoSpace.

  With our acquisition of Saraide Inc. in March 2000, we have begun to expand
our wireless services into Europe, Japan and Canada. We have also entered into
agreements to expand our services into Brazil, China and Australia and are
currently investigating additional international opportunities. The expansion
into international markets involves a number of risks. See "Risk Factors--Risks
Relating to InfoSpace--Our international expansion plans involve risks" for a
description of these risks.

Revenue Sources

  We have derived substantially all of our revenues for our consumer, merchant,
and wireless services from national and local advertising, licensing fees,
commerce transaction fees, and guaranteed transaction fees in lieu of revenue
share.

 Advertising

  National Advertising

  Throughout our consumer services, we sell banner advertisements based on
costs per thousand impressions (CPMs) and other CPM-based national advertising.
Our national advertising agreements generally have terms of less than six
months and guarantee a minimum number of impressions. Actual CPMs depend on a
variety of factors, including, without limitation, the degree of targeting, the
duration of the advertising contract and the number of impressions purchased,
and are often negotiated on a case-by-case basis. Because of these factors,
actual CPMs may fluctuate. Our guarantee of minimum levels of impressions
exposes us to potentially significant financial risks, including the risk that
we may fail to deliver required minimum levels of user impressions, in which
case we typically continue to provide advertising without compensation until
such levels are met.

  Local Internet Yellow Pages Advertising

  We generate a basic Internet yellow pages listing free of charge for all U.S.
local business listings. Similar to traditional yellow pages industry
practices, we generate revenues by selling enhancements to this

                                       88
<PAGE>

basic listing. Internet yellow pages advertising agreements provide for terms
of one year with costs to the local advertisers ranging from $50 to $300 or
greater per year, depending on the types of enhancements selected.

 Subscription Fees

  We receive subscription fees from some of our consumer, merchant and wireless
services. Subscription fees are derived from the distribution of our consumer
services to many of the affiliates in our network. Subscription fees from
merchant services are derived through our reseller relationships with wireless
carriers, device manufacturers, RBOCs, merchant banks and other local media
networks, and include per store/per month fees and per service/per month fees.
Subscription fee agreements for our consumer and merchant services generally
range from one to three years in duration.

 Commerce Fees

  We generate commerce fees from links and completed transactions through our
merchant services delivered on wireless devices and the PC. Under our merchant
services arrangements, merchants agree to pay us a commission-based transaction
fee when a user clicks through to their site and purchases a product. These
commissions typically range from 5 to 25 percent of the purchase amount. These
fees are generally paid to us monthly or quarterly, after the merchant has
collected its payment from the user.

 Guaranteed Transaction Fees

  We have agreements with some affiliates and merchants under which they agree
to pay us guaranteed transaction fees. These arrangements are individually
negotiated and have a range of specially adapted features involving various
compensation structures. These are often based on the range and extent of
customization rather than on CPMs. These arrangements vary in terms and
duration, but generally have longer terms than arrangements for our CPM-based
advertising. In some of these arrangements, we may also receive transaction
revenues when transactions exceed the guaranteed minimum payments. If the
merchant offers a commerce opportunity in its promotion, we may derive
transaction revenues based on the number of transactions made through the
promotion.

  We also have arrangements with wireless carriers, device manufacturers and
software providers whereby we receive guaranteed transaction fees as well as
transaction revenues on a per-subscriber and per-query basis on existing
devices, such as pagers, in excess of the guaranteed minimum payments.

  We generate a significant amount of our revenues from advertising and
guaranteed transaction fees from our affiliates who use our consumer services,
which involves a number of risks. For additional information about these risks,
see "Risk Factors--Risks Relating to InfoSpace--We rely on advertising and
transaction revenues."

Technology and Infrastructure

  One of our principal strengths is our internally developed technology, which
we have designed specifically for our Internet-based consumer, merchant and
wireless services. Our technology architecture features specially adapted
capabilities to enhance performance, reliability and scalability, consisting of
multiple proprietary software modules that support the core functions of our
operations. Our technology includes Web Server Technology, Database Technology,
a Web Scraping Engine, Gateway Technology and database network infrastructure.

 Web Server Technology

  We designed our Web Server Technology to enable rapid development and
deployment of information over multiple platforms and formats. It incorporates
an automated publishing engine that dynamically builds

                                       89
<PAGE>

a page to conform to the look and feel and navigation features of each
affiliate. Our wireless Internet services are device-independent and provide a
platform which enables our wireless carriers to support HDML and SMTP and a
variety of emerging protocols such as WAP, VXML and PQA's for Palm VII. Our
services are compatible with a variety of gateway technologies including WAP
gateways from Nokia, Phone.com and Ericsson.

  Our Web Server Technology includes other features designed to optimize the
performance of our information infrastructure services, including:

  . an HTML compressor that enables modifications of file content to reduce
    size, thereby reducing download time for users;

  . an "Adaptive Keep-Alive" feature that maximizes the time during which
    client server connections are kept open, based on current server load,
    thereby increasing user navigation and Web site traversal speed; and

  . a Proxy Server that provides the capability for real-time integration and
    branding of content that resides remotely with third-party content
    providers.

 Database Technology

  We have developed proprietary database technology to address the specific
requirements of our business strategy and information infrastructure services.
We designed our Co-operative Database Architecture to function with a high
degree of efficiency within the unique operating parameters of the Internet, as
opposed to commonly used database systems that were developed prior to the
widespread acceptance of the Internet. The architecture is tightly integrated
with our Web Server Technology and incorporates the following features:

  Our Heterogeneous Database Clustering allows disparate data sources to be
combined and accessed through a single uniform interface, regardless of data
structure or content. These clusters facilitate database bridging, which allows
a single database query to produce a single result set containing data
extracted from multiple databases, a vital component of our ability to
aggregate content from multiple sources. Database clustering in this manner
reduces dependence on single data sources, facilitates easy data updates and
reduces integration efforts. In addition, our pre-search and post-search
processing capabilities enable users to modify search parameters in real time
before and after querying a database.

  Our Dynamic Parallel Index Traversal mechanism utilizes the search parameters
supplied by the user to determine the appropriate database index (from among
multiple indices) to efficiently locate the data requested. Further, an index
compression mechanism allows us to achieve an efficient balance between disk
space and compression/decompression when storing or accessing data.

  In a response to a database query, conventional databases access previously
displayed results in order to display successive results to a given query, thus
increasing response time by performing redundant operations. Our Automatic
Query State Recovery mechanism decreases response time by maintaining the state
of a query to allow the prompt access of successive results. This feature is
particularly important, for example, when an end-user query retrieves a large
number of results.

  We incorporate a natural word search interpreter, which successfully utilizes
familiar category and topic headings traditional to print directory media to
generate relevant and related results to information queries. By incorporating
a familiar navigation feature into our services, we believe we provide end
users with a more intuitive mechanism to search for and locate information.

  For our merchant services we have developed a comprehensive enterprise-wide
data warehouse. This data warehouse contains information relating to merchants,
products, services, users, customers, profiles,

                                       90
<PAGE>

storefronts, purchases, site traffic and metrics. The aggregation of this
information in one place allows us to leverage our development efforts and
reduce redundant information.

 Web Scraping Engine

  We have developed our Web Scraping Engine to allow data from a variety of
sources on the Internet to be retrieved, parsed and presented as a single
virtual database result, either in real-time or at predetermined intervals. Our
State Machine-Based Profiling system catalogs the data on each source site,
which is later accessed by our Web Scraping Engine for real-time retrieval.
Data results can be internally cached to reduce network traffic and deliver the
fastest possible results to the end user.

  The Web Scraping Engine has numerous applications, one of which is collecting
real-time information from multiple sources in a manner that eliminates the
need for a data provider to perform any local modifications. This technology is
currently being applied in the price comparison feature of our ActiveShopper
merchant service. Various other potential uses of the technology have been
identified, including the collection and real-time updating of event data such
as concert information, performing arts schedules and sporting events, and the
aggregation of classified listings, such as employment listings from corporate
Web sites.

 Gateway Technology

  Our Gateway Technology allows us to take content from one source protocol and
forward it to a device destination that does not include any of the hardware or
software necessary for establishing an Internet connection. The content can be
sent directly or may have some processing performed before transmission to the
destination. This can be used for a single message, or multiple messages sent
on a timed basis such as weather, stock quotes, news and horoscopes. Messages
may be sent to a single user or group of users.

 Data Network Infrastructure

  We maintain a carrier-class data network center designed to ensure high-level
performance and reliability of our information services. We connect directly to
the Internet from our facilities in Bellevue and, until the transition of our
data center is complete, Redmond, Washington through redundant, dedicated DS-3
communication lines provided by multiple telecommunication service providers.
Our hardware resides in a secure climate-controlled room. As we expand our
operations, we expect to locate server facilities at various strategic
geographic locations.

  With the acquisitions of Prio and Saraide, we have data centers in Mountain
View, California serving the promotions technology and Papendrecht, Netherlands
serving wireless customers in Europe.

 Product Development

  We believe that our technology platform is essential to successfully
implement our strategy of expanding our affiliate network, acquiring value-
added content to add to our consumer, merchant and wireless services, expanding
internationally and into other services and maintaining the attractiveness and
competitiveness of our private label solutions. We have invested significant
time and resources in creating our proprietary technology. Product development
expenses were $10.4 million for the six months ended June 30, 2000, $11.3
million for the year ended December 31, 1999, $7.6 million for the year ended
December 31, 1998 and $4.6 million for the year ended December 31, 1997.

  Rapidly changing technology, evolving industry standards, evolving customer
demands and frequent new product and service introductions characterize our
market. See "Risk Factors--Risks Relating to InfoSpace--Rapid technological
change affects our business" for a discussion of certain risks in this regard.

                                       91
<PAGE>

Intellectual Property

  Our success depends significantly upon our proprietary technology. To protect
our proprietary rights, we rely on a combination of copyright and trademark
laws, patents, trade secrets, confidentiality agreements with employees and
third parties and protective contractual provisions. All of our employees have
executed confidentiality and nonuse agreements that transfer any rights they
may have in copyrightable works or patentable technologies to us. In addition,
prior to entering into discussions with potential content providers and
affiliates regarding our business and technologies, we generally require that
such parties enter into nondisclosure agreements with us. If these discussions
result in a license or other business relationship, we also generally require
that the agreement setting forth the parties' respective rights and obligations
include provisions for the protection of our intellectual property rights. For
example, our standard affiliate agreement provides that we retain ownership of
all patents and copyrights in our technology and requires our customers to
display our copyright and trademark notices.

  "InfoSpace" and "ActiveShopper" are registered trademarks of ours. We also
have applied for registration of certain other service marks and trademarks,
including "ActivePromotion" and the "InfoSpace" logo in the United States and
in other countries, and will seek to register additional service marks and
trademarks, as appropriate. We may not be successful in obtaining the service
marks and trademarks for which we have applied. We have been issued one U.S.
patent and have filed 35 U.S. patent applications relating to various aspects
of our technology for querying and developing databases, for developing and
constructing web pages, for electronic commerce for on-line directory services
and for web scraping. Our issued patent covers private-label commerce solutions
and tracking the purchase of products, services and information on the Internet
and on wireless devices. We are preparing additional patent applications on
other features of our technology. We have instituted a formal patent program
and anticipate on-going patent application activity in the future. Patents with
respect to our technology may not be granted, and, if granted, patents may be
challenged or invalidated. In addition, issued patents may not provide us with
any competitive advantages and may be challenged by third parties.

  Despite our efforts to protect our proprietary rights, unauthorized parties
may copy aspects of our products or services or obtain and use information that
we regard as proprietary. The laws of some foreign countries do not protect
proprietary rights to as great an extent as do the laws of the United States.
In addition, others could possibly independently develop substantially
equivalent intellectual property. If we do not effectively protect our
intellectual property, our business could suffer.

  Companies in the Internet services industry have frequently resorted to
litigation regarding intellectual property rights. We may have to litigate to
enforce our intellectual property rights, to protect our trade secrets or to
determine the validity and scope of other parties' proprietary rights. From
time to time, we have received, and may receive in the future, notice of claims
of infringement of other parties' proprietary rights. Any such claims could be
time-consuming, result in costly litigation, divert management's attention,
cause product or service release delays, require us to redesign our products or
services or require us to enter into royalty or licensing agreements. These
royalty or licensing agreements, if required, may not be available on
acceptable terms or at all. If a successful claim of infringement were made
against us and we could not develop non-infringing technology or license the
infringed or similar technology on a timely and cost-effective basis, our
business could suffer. See "--Legal Proceedings."

Competition

  We operate in the Internet information infrastructure services market, which
is extremely competitive and is rapidly changing. Our current and prospective
competitors include many large companies that have substantially greater
resources than we have. We believe that the primary competitive factors in the
market for Internet information infrastructure services are:

  . the ability to provide information of broad appeal, which is likely to
    result in increased user traffic and increase the brand name value of the
    Web sites and wireless devices to which the services are provided;

                                       92
<PAGE>

  . the ability to meet the specific information and service demands of a
    particular Web site or wireless device;

  . the cost-effectiveness and reliability of the consumer, merchant or
    wireless information services;

  . the ability to provide consumer, merchant or wireless information
    services that are attractive to advertisers and end users;

  . the ability to achieve comprehensive coverage of a particular category of
    information or services; and

  . the ability to integrate related information to increase the utility of
    the consumer, merchant or wireless information services offered.

  We compete, directly or indirectly, in the following ways, among others:

  . our directory services compete with AnyWho? (a division of AT&T), GTE
    SuperPages, Switchboard, ZIP2 (which was acquired by Compaq), various
    RBOCs' directory services, infoUSA's Lookup USA, City Search's Sidewalk
    and Yahoo! Yellow Pages and White Pages;

  . other information services we provide, such as classifieds, horoscopes
    and real-time stock quotes, compete with specialized content providers;

  . our U.K. operations compete with British Telecom's YELL service and Scoot
    (UK) Limited in directory services; Inktomi and Autonomy in
    infrastructure services, Excite, Yahoo! and MSN in syndication;
    Shopguide, Shopsmart and Yahoo! shopping for merchant services and
    various specialized content providers for information services;

  . our community and communication services compete with services offered by
    Internet portals such as AOL, Yahoo!, and Excite, as well as specialized
    content service providers such as Hotmail;

  . our merchant services compete with e-tailers such as Amazon.com, portals
    such as AOL, Yahoo! and MSN, merchant aggregators such as Big Step and
    Microsoft's Bcentral and infrastructure providers such as Inktomi; and

  . our wireless services compete with portals such as AOL, Yahoo!, MSN and
    Lycos, with specialized content providers, and with software companies
    like Phone.com (which recently agreed to merge with Software.com).

  We expect that in the future we will experience competition from other
Internet services companies and providers of Internet software, including
Microsoft, Yahoo!, AOL, Excite, Disney, Lycos and NBC's Snap. Some of these
companies are currently customers of ours, the loss of which could harm our
business. We may also face increased competition from traditional media
companies expanding onto the Internet.

  Many of our current customers have established relationships with certain of
our current and potential future competitors. If our competitors develop
information infrastructure services that are superior to ours or that achieve
greater market acceptance than ours, our business will suffer.

Governmental Regulation

  Because of the increasing use of the Internet, U.S. and foreign governments
have adopted or may in the future adopt laws and regulations relating to the
Internet, addressing issues such as user privacy, pricing, content, taxation,
copyrights, distribution and product and services quality.

  Recent concerns regarding Internet user privacy has led to the introduction
of U.S. federal and state legislation to protect Internet user privacy.
Existing laws regarding user privacy that we may be subject to include the
Children's Online Privacy Protection Act, which regulates the online collection
of personal information from children under 13, and the Gramm-Leach-Bliley Act,
which regulates the collection and processing of personal financial
information. In addition, the Federal Trade Commission has initiated

                                       93
<PAGE>

investigations and hearings regarding Internet user privacy which could result
in rules or regulations that could adversely affect our business. As a result,
we could become subject to new laws and regulations that could limit our
ability to conduct targeted advertising, or to distribute or collect user
information.

  European legislation to protect Internet user privacy has not heretofore
greatly impacted us. In October 1998, the European Union adopted a directive
that may limit our collection and use of information regarding Internet users
in Europe. European countries may pass new laws in accordance with the
directive, or may seek to more strictly enforce existing legislation, which may
prevent us from offering some or all of our services in some European
countries.

  We may be subject to provisions of the Federal Trade Commission Act that
regulate advertising in all media, including the Internet, and require
advertisers to substantiate advertising claims before disseminating
advertising. The Federal Trade Commission has the power to enforce this Act. It
has recently brought several actions charging deceptive advertising via the
Internet and is actively seeking new cases involving advertising via the
Internet.

  We may also be subject to the provisions of the recently enacted
Communications Decency Act. This Act imposes substantial monetary fines and/or
criminal penalties on anyone who distributes or displays certain prohibited
material over the Internet. Also recently enacted was the Children's Online
Protection Act, which restricts the distribution of certain materials deemed
harmful to children. Although some court decisions have cast doubt on the
constitutionality of these Acts, they could subject us to substantial
liability.

  These or any other laws or regulations that may be enacted in the future
could have several adverse effects on our business. These effects include:

  .  we may be subject to substantial liability, including fines and criminal
     penalties;

  .  we may incur substantial expense in order to comply with such laws and
     regulations;

  .  we could be prevented from offering certain products or services; and

  .  the growth in Internet usage could be substantially limited.

  There is substantial uncertainty as to how existing laws and regulations,
including those relating to privacy, taxation and intellectual property, apply
to activities conducted on the Internet. Also, due to the global nature of the
Internet, it is possible that governments of states or countries in which we
did not knowingly conduct business may attempt to regulate our activities of
prosecute us for violations of their laws. To the extent that there is
uncertainty in the application of existing laws, or that new laws are enacted
in the future, we cannot predict the impact these laws may have on our
business.

Employees

  At June 30, 2000, we had 502 employees. None of our employees is represented
by a labor union, and we consider our employee relations to be good.
Competition for qualified personnel in our industry is intense, particularly
for software development and other technical staff and for personnel with
experience in wireless services. We believe that our future success will depend
in part on our continued ability to attract, hire and retain qualified
personnel. See "Risk Factors--Risks Relating to InfoSpace--We need to manage
our growth and maintain procedures and controls" and "--We depend on key
personnel" and "--We need to hire additional personnel."

Facilities

  In June 2000 we relocated to significantly larger facilities under a lease
for a new principal administrative, engineering, marketing and sales facility
located in Bellevue, Washington totaling approximately 131,118 square feet.
Under the five-year lease, we will pay a monthly base rent of $250,825

                                       94
<PAGE>

per month during the first year, $252,647 per month during the second year,
$263,551 per month during the third year, $265,373 per month during the fourth
year and $276,276 per month during the final year.

  Previously, our principal administrative, engineering, marketing and sales
facilities totaled approximately 16,864 square feet and were located in
Redmond, Washington. Under that lease, which commenced on July 13, 1998, and
expires on August 31, 2003, we pay a monthly base rent of $19,775 through
August 2001 and $22,030 during the final two years of the lease. Subsequent to
our move to Bellevue, we continue to maintain our data center in Redmond and
have sublet the remaining space to third parties.

  We maintain a sales office housed in an approximately 2,271-square-foot space
in San Francisco, California under a lease that expires on November 30, 2001
with a monthly base rent of $5,299. We also maintain a sales office in New York
City for 1,900 square feet with a monthly base rent of $3,667, under a lease
that expires April 2004. We do not own any real estate.

  With the acquisitions of Saraide and Prio, we now have facilities in Mountain
View and San Mateo, California; Ottawa, Canada; Papendrecht, Netherlands; and
London, United Kingdom. Also, we recently established offices in Australia and
Brazil.

  We are currently transitioning our computer and communications hardware from
our facilities in Redmond, Washington to our new headquarters in Bellevue,
Washington. We intend to install additional hardware and high-speed Internet
connections at a location outside the West Coast as well as in the
United Kingdom.

  Our systems and operations at these locations are vulnerable to damage or
interruption from fire, flood, power loss, telecommunications failure, break-
ins, earthquake and similar events. See "Risk Factors--Risks Relating to
InfoSpace--Our business relies on the performance of our systems."

Legal Proceedings

  From time to time we have been, and expect to continue to be, subject to
legal proceedings and claims in the ordinary course of our business, including
claims of alleged infringement of third-party trademarks and other intellectual
property rights by us. These claims, even if not meritorious, could require the
expenditure of significant financial and managerial resources.

  On December 15, 1999, a former employee filed a complaint against us in
federal court in New Jersey alleging claims for breach of contract, breach of
the covenant of good faith and fair dealing, fraud, negligent
misrepresentation, and promissory estoppel. The former employee contends he
agreed to work for InfoSpace on the basis of certain misrepresentations, that
he entered into an agreement with us that entitles him to an option to purchase
300,000 shares of our common stock, and that he was terminated without cause.
The former employee seeks (1) the right to purchase 300,000 shares of our
common stock, (2) unspecified compensatory and punitive damages, and (3)
litigation costs and attorney's fees. On January 31, 2000, we answered the
complaint, denying the claims. Discovery is complete. The case has been
transferred to the United States District Court for the Western District of
Washington, and trial has not yet been set. We are currently investigating the
claims at issue and believe we have meritorious defenses to such claims.
Nevertheless, litigation is uncertain and we may not prevail in this suit.

  On February 18, 1999, a former consultant filed a complaint in the Superior
Court for Santa Clara County, California alleging, among other things, that he
had the right in connection with his consulting to the company to purchase
56,924 shares of our common stock. We settled this lawsuit in September 1999.
Under the settlement, we permitted the former consultant to purchase 33,012
shares of our common stock at a price of $.05 per share.

  On January 26, 1999, Civix-DDI, LLC filed a complaint in the U.S. District
Court in Colorado against us and 19 other defendants for infringement of two
patents relating to electronic mapping systems. In July

                                       95
<PAGE>

1999 we settled this litigation by entering into a license agreement for these
patents, pursuant to which we made a single lump sum royalty payment.

  On December 23, 1998, we initiated litigation against Internet Yellow Pages,
Inc. ("IYP") by filing suit in United States District Court for the Western
District of Washington. On February 3, 1999, we served a first amended
complaint on IYP and Greg Crane, an agent of IYP, in which we asserted claims
for (a) account stated, (b) breach of contract, and (c) fraud. On March 5,
1999, IYP answered our complaint in the Washington action, and asserted claims
for breach of contract, fraud, extortion and Consumer Protection Act
violations. IYP seeks relief consisting of approximately $1,500,000 and other
unquantified money damages, treble damages under the CPA, and attorneys' fees.
Discovery is complete. We are currently investigating the claims at issue and
believe we have meritorious defenses to such claims. Nevertheless, litigation
is uncertain and we may not prevail in these suits. The case is scheduled for a
streamlined mini-trial before a federal magistrate on October 2, 2000.

  On December 7, 1998, a complaint was filed against us on behalf of an alleged
former employee in Superior Court for Suffolk County in the Commonwealth of
Massachusetts alleging that he was terminated without cause and that he entered
into an agreement with us that entitles him to an option to purchase 4,000,000
shares of our common stock or 10% of our equity. We settled this lawsuit in
February 2000. Under the settlement, we made a cash payment of $10.5 million.

  On April 16, 1998, one of our former employees filed a complaint in the
Superior Court for Santa Clara County, California alleging, among other things,
that he had the right in connection with his employment to purchase shares of
our common stock representing up to 5% of our equity as of an unspecified date.
We settled this lawsuit in February 1999. Under the settlement, we made a cash
payment of $4.5 million.

  We had discussions with a number of individuals in the past regarding
employment by us and also hired and subsequently terminated a number of
individuals as employees or consultants. Furthermore, primarily during our
early stage of development, our procedures with respect to the manner of
granting options to new employees were not clearly documented. As a result of
these factors, and in light of the receipt of the above claims, we have in the
past received, and may in the future receive, similar claims from one or more
individuals asserting rights to acquire shares of our stock or to receive cash
compensation. We cannot predict whether such future claims will be made or the
ultimate resolution of any currently outstanding or future claim.

Overview

  InfoSpace, Inc. is an international information infrastructure services
company. InfoSpace provides commerce, information and communication
infrastructure services for wireless devices, merchants and Web sites. We began
operations in March 1996. During the period from inception through December 31,
1996, we had insignificant revenues and were primarily engaged in the
development of technology for the aggregation, integration and distribution of
Internet content and the hiring of employees. In 1997, we expanded our
operations, adding business development and sales personnel in order to
capitalize on the opportunity to generate Internet advertising revenues. We
began generating material revenues in 1997 with our consumer services. Revenues
in 1998 were also primarily generated through our consumer services. Throughout
1999 and the first half of 2000, we have expanded our infrastructure services
to enhance our consumer, merchant and wireless services. At June 30, 2000, we
had 502 employees. The following provides greater detail on each of our service
offerings:

  Consumer Services: We provide information of broad appeal to users of
wireless devices and PC's including directories, sports, news and
entertainment, financial data and traffic reports. We also offer an integrated
platform of consumer services that includes community building services such as
online address books, calendars, online chat and message boards, and
communication services including device independent e-mail and instant
messaging. Our consumer services are designed for the end user and are
distributed through wireless devices and Web sites. Our affiliate network
consists of more than 3,100 portals and affinity Web sites.

  Revenues from our consumer services are generated from advertising,
subscriber fees and guaranteed transaction fees in lieu of revenue share.

  Merchant Services: We provide comprehensive end-to-end merchant services and
an extensive distribution network that includes regional bell operating
companies (known as RBOCs), merchant banks and other local media networks. Our
end-to-end merchant services give merchants the ability to create, promote,
sell and distribute their products and services across multiple channels
through our broad distribution network. We have extensive reseller agreements
with RBOCs, including BellSouth, SBC, Verizon, and Qwest, merchant banks such
as American Express and Bank of America and other local media networks such as
newspapers and television and radio stations who provide our services to
millions of local merchants worldwide.

                                       97
<PAGE>

  Our merchant services consist of a comprehensive platform of technology that
enables us to deliver unique services such as:

  . the online delivery of promotions to any device that can be used online
    and offline;

  . buying from any Web site directly from a wireless device with a single
    click;

  . PageExpress(TM) which enables local merchants to create a Web presence;

  . StoreBuilder which enables merchants to build online stores;

  . ActivePromotion(TM) which enables merchants to create targeted product
    promotions and distribute them across our network;

  . ActiveShopper(TM) which provides an open marketplace where consumers can
    find, research and purchase products from our merchant network; and

  . Yellow page listings and enhanced listings.

  Revenues from our merchant services are primarily generated from commerce
fees and subscriber fees, including per store/per month or per promotion/per
month fees. Our national and local merchant network consists of more than
600,000 local and national merchants.

  Wireless Services: Our wireless services are comprised of a comprehensive,
integrated suite of wireless portal services that provide mobile users relevant
information services such as real-time stock quotes and traffic reports, the
ability to conduct secure commerce transactions including single click buying,
communication services such as device-independent instant messaging and e-mail,
personalization capabilities and location-based services that enable the user
to search for location-based information such as the restaurant closest to the
mobile user's current location. These services are distributed through wireless
carriers, device manufacturers and software providers. Our wireless affiliates
include Verizon Wireless, AT&T Wireless, SBC and ALLTELL.

  Our wireless services are private-labeled for each carrier, preserving the
brand of the carrier and their relationship with their customer and creating a
barrier to switch. Revenues are primarily generated from the carrier and
include licensing fees, per subscriber/per month fees in the U.S. and per
query/per message fees in Europe and Japan. In addition we receive commerce
revenue for the transactions delivered on the wireless devices.

  All of our services are built on our core technology platform and use the
same operational infrastructure. We do not allocate development or operating
costs to any of these services.

Recent Acquisitions

  In May 1997, we acquired Yellow Pages on the Internet, LLC, or YPI, a
Washington limited liability company that provided Internet yellow pages
directory information. In June 1998, we acquired Outpost, a Washington
corporation engaged primarily in electronic commerce through the sale of cards
and gifts via the Internet. In June 1999, we acquired the MyAgent technology
and related assets from Active Voice Corporation. In October 1999, we acquired
Union-Street.com, a provider of business services including private label e-
mail, address book, calendar, personal home page, chat and message boards. In
December 1999, we acquired eComLive.com, Inc., a provider of Web-based real-
time collaboration and interaction solutions specialized for consumer-to-
consumer, business-to-business and business-to-consumer vertical markets and
Zephyr Software Inc., an infrastructure services company for the Indian market.
These acquisitions were accounted for under the purchase method and,
accordingly, are included in our operating results from the date of acquisition
forward. The impact of the YPI acquisition on our consolidated statement of
operations was not substantial. The acquisitions of Outpost, MyAgent, Union-
Street and eComLive resulted in write-offs of in-process research and
development and the recording of goodwill, assembled

                                       98
<PAGE>

workforce and core technology. The acquisition of Zephyr Software resulted in
the recording of goodwill. We have integrated these businesses and the acquired
technologies with our other products and services.

  In October 1999, we acquired INEX Corporation, a developer of Internet
commerce solutions designed for small and medium-sized merchants. This
transaction was accounted for as a pooling-of-interests. The consolidated
financial statements for the three years ended December 31, 1999 and the
accompanying notes reflect the Company's financial position and results of
operations as if INEX was a wholly-owned subsidiary since inception.

  In February 2000, we acquired Prio, Inc., a provider of commerce solutions
specializing in the development of strategic partnerships, technologies and
programs that drive commerce in both traditional and online shopping
environments. The consolidated financial statements and accompanying notes
reflect the Company's financial position and results of operations as if Prio
was a wholly-owned subsidiary since inception. In March 2000, we acquired an
eighty-percent interest in Saraide Inc. (formerly saraide.com, inc), a provider
of wireless Internet services in Europe, Japan and Canada. Also in March 2000,
we acquired Millet Software (privacybank.com). Millet developed secure
technology that provides an automated process for filling in payment forms. The
acquisitions of Saraide and Millet are accounted for as purchases and their
results of operations are included in the consolidated financial statements
from the date of acquisition.

  In July 1998, we entered into a joint venture agreement with TDLI.com
Limited, a subsidiary of Thomson Directories Limited, to form TDL InfoSpace to
replicate our content, community and consumer services in Europe. TDL InfoSpace
launched content services in the United Kingdom in the third quarter of 1998.
Under the Web site services agreement, Thomson provides its directory
information to TDL InfoSpace and sells Internet yellow pages advertising for
the joint venture through its local sales forces. We also license our
technology and provide hosting services to TDL InfoSpace. Thomson and we each
purchased a 50% interest in TDL InfoSpace and are required to provide
reasonable working capital to TDL InfoSpace. As of December 31, 1999, we had
contributed $496,000 to the joint venture. We account for our investment in the
joint venture under the equity method. For the years ended December 31, 1999
and 1998, we recorded losses from the joint venture of $12,000 and $125,000,
respectively. On August 31, 2000, we acquired all of the issued and outstanding
capital stock of TDLI.com Limited. This acquisition gave us 100% control of TDL
InfoSpace.

  We have incurred losses since our inception and, as of June 30, 2000, we had
an accumulated deficit of approximately $213.5 million. For the six months
ended June 30, 2000, our net loss totaled $114.9 million, including
amortization of intangibles of $27.4 million, $86.6 million in acquisition and
related charges associated with the acquisitions of Prio, Saraide and Millet
and $2.9 million in other non-recurring charges related to warrants issued by
Prio for services provided. For the year ended December 31, 1999, our net loss
totaled $57.6 million, including $13.4 million in acquisition and related
charges and $11.4 million in other non-recurring charges. See "--Acquisitions"
and "InfoSpace Business--Legal Proceedings."

  We believe that our future success will depend largely on our ability to
continue to offer consumer, merchant and wireless solutions that are attractive
to our existing and potential future affiliates and distribution partners.
Accordingly, we plan to significantly increase our operating expenses in order
to, among other things:

  . expand our affiliate network, which may require us to pay additional
    carriage fees to certain affiliates;

  . expand our business development and marketing operations and hire more
    sales and business development personnel;

  . increase our advertising and promotional activities;

  . develop and upgrade our technology and purchase equipment for our
    operations and network infrastructure;

                                       99
<PAGE>

  . expand internationally; and

  . expand our commerce, merchant and wireless services.

  After giving effect to our recent acquisitions, we expect to incur
significant operating losses on a quarterly basis in the future. In light of
the rapidly evolving nature of our business and limited operating history, we
believe that period-to-period comparisons of our revenues and operating results
are not necessarily meaningful, and you should not rely upon them as
indications of future performance. Although we have experienced sequential
quarterly growth in revenues over the past twelve quarters, we do not believe
that our historical growth rates are necessarily sustainable or indicative of
future growth. For information on recent and pending acquisitions see "--
Acquisitions."

</TABLE>

Results of Operations for the Years Ended December 31, 1997, 1998 and 1999 and
Six Months Ended June 30, 1999 and 2000

  Revenues. Currently our revenues are derived from our consumer, merchant and
wireless services. These include advertising, subscriber fees, commerce
transaction fees, and guaranteed transaction fees in lieu of revenue share. We
tailor agreements to fit the needs of our customers, affiliates and
distribution partners, and under any one agreement we may earn revenue from a
combination of these sources. We also have agreements that utilize services
from more than one of our areas of service. Revenues were $37.4 million the
year ended December 31, 1999, $9.6 million the year ended December 31, 1998 and
$1.8 million for the year ended December 31, 1997. The increases are primarily
due to significant growth in our consumer and merchant services as a result of
increased expansion of our affiliate network, increased traffic to our
affiliate network that results in increased page views, increased use of our
consumer, merchant and wireless services, as well as larger and longer term
agreements with advertisers, affiliates and

                                      100
<PAGE>

distribution partners. We entered into 286 new agreements with advertisers,
affiliates and distribution partners during the year ended December 31, 1999.

  Revenues increased $31.3 million, or 256%, to $43.6 million in the six-month
period ended June 30, 2000 from the comparable period in 1999. This increase is
due primarily to significant growth in our consumer and merchant services as a
result of the expansion of our affiliate network, which consists of more than
3,100 Web sites and wireless devices and increased use of our consumer,
merchant and wireless services, as well as larger and longer term agreements
with advertisers, affiliates and distribution partners.

  Cost of Revenues. Cost of revenues consists of expenses associated with the
enhancement, maintenance and support of our consumer, merchant and wireless
services, including direct personnel expenses, communication costs such as
high-speed Internet access, server equipment depreciation, and content license
fees. Cost of revenues were $7.3 million, or 19% of revenues, for the year
ended December 31, 1999 compared to $2.3 million, or 24% of revenues, for the
year ended December 31, 1998 and $493,000, or 27% of revenues, for the year
ended December 31, 1997. Cost of revenues were $7.6 million, or 17% of
revenues, for the six-month period ended June 30, 2000 compared to $3.0
million, or 24% of revenues, for the six-month period ended June 30, 1999. The
absolute dollar increases are primarily attributable to personnel costs and
other costs incurred in order to support greatly increased delivery of our
consumer, merchant and wireless solutions, including communication lines, data
licenses and equipment. We expect the absolute dollars spent on personnel,
enhanced content and expanded communications will continue to increase in the
foreseeable future. We currently anticipate that cost of revenues will be in
the high teens as a percentage of revenues for the remainder of 2000.

  Product Development Expenses. Product development expenses consist
principally of personnel costs for research, design and development of the
proprietary technology we use to integrate and distribute our consumer,
merchant and wireless services. Product development expenses were $11.3 million
or 30% of revenues for the year ended December 31, 1999, compared to $7.6
million or 79% of revenues, for the year ended December 31, 1998 and $4.6
million, or 251% of revenues, for the year ended December 31, 1997. Product
development expenses increased $5.5 million to $10.4 million in the six-month
period ended June 30, 2000, from $4.9 million for the comparable period in
1999. The increases in absolute dollars are primarily attributable to increases
in engineering personnel needed for continued development of our products and
service offerings. We believe that significant investments in technology are
necessary to remain competitive. Accordingly, we expect product development
expenses to continue to increase in absolute dollars as we hire additional
personnel who will develop and enhance our proprietary technology.

  Sales, General and Administrative Expenses. Sales, general and administrative
expenses consist primarily of salaries and related benefits for sales, general
and administrative personnel, advertising and promotion expenses, carriage
fees, professional service fees, occupancy and general office expenses and
travel expenses. Sales, general and administrative expenses were $60.1 million
or 161% of revenues, for the year ended December 31, 1999 compared to $18.2
million or 189% of revenues, for the year ended December 31, 1998 and $6.5
million or 360% of revenues, for the year ended December 31, 1997. The absolute
dollar increases from the prior year were primarily due to increased staffing
levels necessary to manage and support our sales and operations teams, carriage
fees paid to certain affiliates, increased advertising and expansion of our
facilities and professional services. Sales, general and administrative
expenses were $35.5 million, or 81% in the six-month period ended June 30,
2000, compared to $18.7 million or 153% for the comparable period in 1999. The
absolute dollar increase is primarily due to increased personnel costs,
carriage fees paid to certain affiliates to include our content services on
their Web sites and travel expenses. Included in the 1999 expense is $17.7
million of expense recorded for the fair market value of warrants issued by
Prio, Inc. Prio had issued warrants for services provided.

  Amortization of Intangibles. Amortization of intangibles includes
amortization of goodwill, core technology, purchased domain names, trademark,
contract lists and assembled workforce. Amortization of intangibles was $3.2
million in 1999, compared to $710,000 in 1998 and $64,000 in 1997. Amortization
of

                                      101
<PAGE>

intangibles was $27.4 million in the six months ended June 30, 2000, compared
to $604,000 in the six months ended June 30, 1999. The increases are a result
of amortization of intangibles recorded from the acquisitions of Saraide and
Millet Software in March 2000, Zephyr Software and eComLive in December of
1999, Union-Street in October 1999, the MyAgent technology acquisition in June
1999 and Outpost Network in July 1998. With the exception of Zephyr,
intangibles of applicable goodwill, core technology, contract list and acquired
workforce for each acquisition are being amortized over five years. The
amortization of goodwill for Zephyr is over three years. We acquired IQOrder on
July 3, 2000. Amortization expense for the intangibles acquired in this
transaction will be included in the third quarter of 2000. In the event that we
complete additional acquisitions, which we expect to do, expenses relating to
the amortization of intangibles could increase in the future.

  Acquisition and Related Charges. Acquisition and other related charges
consist of in-process research and development and other one-time charges
related directly to acquisitions, such as legal and accounting fees. The
acquisition and related charges in 1999 were one-time in-process research and
development charges and costs incurred in the purchase acquisitions of
eComLive, Union-Street and the My Agent technology. Also included in
acquisition and other related charges in 1999 are the costs incurred in the
acquisition of INEX, which was accounted for as a pooling-of-interests. Total
in-process research and development charges in 1999 were $9.2 million. The
acquisition and related charges in the six months ended June 30, 2000 were one-
time in-process research and development charges and costs incurred in the
purchase acquisitions of Saraide and Millet Software. Also included in
acquisition and other related charges in 2000 are the costs incurred in the
acquisition of Prio, which was accounted for as a pooling of interests
transaction. Total in-process research and development charges in the first six
months of 2000 was $74.1 million. We expect to continue to pursue an aggressive
growth strategy to enhance and expand our consumer, merchant and wireless
services. In the event we complete additional acquisitions, we could incur
additional acquisition and related charges in the future.

  Other Non-Recurring Charges. Other non-recurring charges in 1999 consist of
costs associated with litigation settlements. In February 2000, we reached a
settlement with an alleged employee in a lawsuit for a cash payment of $10.5
million. We accrued and expensed this liability in 1999. On July 23, 1999, we
settled a patent infringement claim in exchange for a lump sum royalty payment
of $209,500. This expense was recorded in 1999. On February 22, 1999, we
reached a settlement with a former employee for a cash payment of $4.5 million.
We accrued and expensed this liability in 1998.

  In the six months ended June 30, 2000 other non-recurring charges consisted
of an expense recorded for the fair market value of warrants issued by Prio.
Prio had previously issued warrants for services provided. These warrants were
accounted for under variable plan accounting. Subsequent to the acquisition of
Prio, the agreement pursuant to which these warrants were granted was
terminated and the remaining unvested warrants accelerated to full vesting. For
1999 the warrant expense was $17,652,693 and for the six months ended June 30,
2000 the warrant expense was $2,887,609. As these warrants are fully vested, no
additional expense for these warrants will be recorded in future periods.

  Unrealized Gain on Investments Held. Unrealized gain on investments held
represents the unrealized gain on the investments in the InfoSpace Venture
Capital Fund 2000 of which InfoSpace owned 59.2% as of June 30, 2000. In
accordance with Accounting for Investments in Venture Capital Funds, the
investments are recorded at their market value and the unrealized gains are
reflected in the income statement in the Fund, which is fully consolidated. The
unrealized gain recognized in the six months ended June 30, 2000 is not
necessarily indicative of future results.

  Minority Interest in Venture Capital Fund. As the majority holder in the
InfoSpace Venture Capital Fund 2000, we have recorded 100% of the balance sheet
and statement of operations in our consolidated financial statements. The non-
InfoSpace portion of the net income in the fund has been reflected as minority
interest. As of June 30, 2000, InfoSpace owned 59.2% of the fund, our employees
owned the remaining 40.8% of the fund.

                                      102
<PAGE>

  Restructuring Charges. Restructuring charges of $2.2 million for the six
months ended June 30, 2000 reflect actual and estimated costs associated with
the closure of our Dallas, Texas facility. These costs are primarily comprised
of the write off of leasehold improvements, early lease termination penalties,
relocation costs and other personnel costs. We acquired this facility in the
acquisition of Saraide, Inc in March of 2000. Our decision to close this office
was primarily due to duplicated efforts in this facility and our other
locations and the forecasted cost savings from the closure of the facility.

  Other Income, Net. Other income consists primarily of interest income for all
periods. Other income was $11.7 million in 1999, $593,000 in 1998 and $39,000
in 1997. Other income was $6.0 million in the six months ended June 30, 2000,
compared to $4.6 million from the comparable period of 1999. The increase from
the prior years is primarily due to interest earned on higher average cash
balances resulting from private financings in July and August of 1998, the net
proceeds from our initial public offering completed in December 1998, and the
net proceeds from our follow-on offering, which closed in April 1999.

  We have reinvested and will continue to reinvest part of our fixed income
securities in equity investments. We anticipate that our expansion plans may
require greater cash uses in the remainder 2000 than in prior years. With these
two factors, we anticipate that our interest income from our fixed securities
will decrease in the remainder 2000, compared with 1999.

  Provision for Income Taxes and Income Tax Expense. Net operating losses have
been incurred to date on a cumulative basis, and no tax benefit has been
recorded, as sufficient uncertainty exists regarding the realizability of the
deferred tax assets. The income tax expense in the six months ended June 30,
2000 is from our international operations in Europe.

Balance Sheet Commentary

  Accounts Receivable. As we enter into agreements for larger amounts with
larger, well established companies, we periodically must provide extended
payment terms beyond our standard 15 to 30 day terms to allow for the
customer's internal approval and payment processing systems. In addition, we
are issuing single invoices for larger dollar amounts. For example, at June 30,
2000 the receivable from one customer represented 23% of the accounts
receivable balance. This amount was received within payment terms subsequent to
period end.

  Allowance for Doubtful Accounts. We specifically reserve all accounts sixty
days or more past due. In addition, we reserve an amount based on revenues and
the accounts receivable balance for accounts not specifically identified.

  We have a stringent credit review process and require payment in advance from
those customers that do not qualify under our trade credit guidelines.

  Deferred Revenue. The increase in the six months ending June 30, 2000 was
primarily due to prepayment under two new large contracts closed during the
quarter and our policy put in place at the beginning of the year of obtaining
payment from customers in advance of delivering services whenever practicable.

Liquidity and Capital Resources

  From our inception in March 1996 through May 1998, we funded operations with
approximately $1.5 million in equity financing and, to a lesser extent, from
revenues generated for services performed. In May 1998, we completed a $5.1
million private placement of our common stock, and in July and August 1998, we
completed an additional private placement of our common stock for $8.2 million.
Sales of our common stock to employees pursuant to our 1998 Stock Purchase
Rights Plan also raised $1.7 million in July 1998. Our initial public offering
in December 1998 yielded net proceeds of $77.8 million and a follow-on

                                      103
<PAGE>

public offering in April 1999 yielded net proceeds of $185.0 million. As of
June 30, 2000, we had cash, cash equivalents and short-term investments of
$146.7 million and long-term investments of $76.5 million.

  Net cash used by operating activities was $34.9 million in 1999. Cash used in
operating activities for the year ended December 31, 1999 consisted primarily
of net operating losses and increases in accounts receivable, notes receivable
and prepaid expenses. These uses of cash were partially offset by increases in
accrued expenses. Net cash used by operating activities was $13.6 million in
1998. Cash used in operating activities in 1998 consisted primarily of net
operating losses and increases in accounts receivable and prepaid expenses.
These uses of cash were partially offset by increases in accrued expenses. Net
cash used by operating activities was $7.3 million in 1997, which was primarily
comprised of the net loss. Net cash used by operating activities was $21.1
million in the six months ended June 30, 2000, consisting primarily of net
operating losses and decreases in accounts payable. Net cash used by operating
activities of $13.5 million during the six months ended June 30, 1999 consisted
primarily of net operating losses.

  Net cash used by investing activities was $159.7 million in the year ended
December 31, 1999. For 1999, cash used in investing activities was primarily
comprised of business acquisitions, securities investments, other investments
and purchase of fixed assets. The change in securities investments is primarily
a result of investing proceeds from our follow-on offering in short and long-
term investments. Net cash used in investing activities in 1998 was $83.7
million. This was primarily a result of investing the cash proceeds from the
initial public offering in short and long-term investments. Net cash used by
investing activities in 1997 was $958,000 and was primarily for the purchase of
fixed assets. Net cash provided by investing activities was $23.9 million in
the six months ended June 30, 2000. For this period, cash provided by investing
activities was primarily comprised of the reduction of short-term and long-term
investments and inclusion of minority interest. This cash increase was offset
by business acquisition costs, issuance of notes receivable and additional
investments. Net cash used by investing activities during the six months ended
June 30, 1999 was $104.4 million. This was primarily a result of investing the
cash proceeds from the initial public offering in short and long-term
investments.

  Cash provided by financing activities in 1999 was $192.6 million and was
primarily comprised of our net proceeds from our follow-on offering in April
1999. Cash provided by financing activities in 1998 was $125.3 million. The
1998 net proceeds were primarily from our initial public offering and, to a
lesser extent, from private placements of common stock. Cash provided by
financing activities in 1997 was primarily from private placements of our
common stock. Cash used in financing activities in the six months ended June
30, 2000 of $4.8 million was primarily comprised of the payoff of debt assumed
in the acquisition of Saraide and was offset by proceeds from the exercise of
stock options, warrants and issuance of shares under our 1998 Employee Stock
Purchase Plan. Cash provided by financing activities in the six months ended
June 30, 1999 of $187.8 was primarily comprised of proceeds from the sale of
common stock in our follow-on offering in April 1999.

  We plan to use our cash for strategic investments and acquisitions,
investments in internally developed technology, global expansion of our
services and continued build-out of infrastructure in Europe, Asia and South
America.

  We believe that existing cash balances, cash equivalents and cash generated
from operations will be sufficient to meet our anticipated cash needs for
working capital and capital expenditures for at least the next 12 months.
However, the underlying assumed levels of revenues and expenses may not prove
to be accurate. We may seek additional funding through public or private
financings or other arrangements prior to such time. Adequate funds may not be
available when needed or may not be available on favorable terms. If we raise
additional funds by issuing equity securities, dilution to existing
stockholders will result. If funding is insufficient at any time in the future,
we may be unable to develop or enhance our products or services, take advantage
of business opportunities or respond to competitive pressures, any of which
could harm our business. See "Risk Factors--Risks Relating to InfoSpace--We may
require additional funding."

Acquisitions

  Orchest, Inc. On August 4, 2000 we acquired all of the outstanding capital
stock of Orchest, Inc., a privately held company based in Cupertino,
California, for a purchase consideration of 255,288 shares of our common stock.
Orchest is an online provider of financial services that enables users to
access a consolidated view of their personal financial information from
multiple institutions. The acquisition was accounted for as a purchase.

  IQorder.com, Inc. On July 3, 2000, we acquired Tempe, Arizona-based
IQorder.com, a company that has developed technology that allows consumers to
enter in a model number, UPC code, part number, barcode or ISBN to locate a
product, compare prices and make an instant purchase. Under the terms of the
acquisition, which will be accounted for as a purchase, we exchanged 989,959
shares of our common stock for all of IQorder's outstanding shares, warrants
and options valued at $58 million.

  Millet Software. On March 31, 2000 we acquired all of the common stock of
Millet Software, a privately held company, for a purchase consideration of
488,224 shares of our common stock and acquisition expenses of $54,531. The
acquisition was accounted for as a purchase in accordance with the provisions
of APB No. 16.

  In this transaction, we assumed net assets of $5.9 million. This includes
$6.0 million in purchased technology which includes in-process research and
development, $170,000 of acquired workforce and $294,020 in net liabilities. We
issued shares with a fair value of $29.6 million and incurred acquisition costs
of $54,531. This resulted in $18.5 million of goodwill.

  We recorded a non-recurring charge of $2.4 million for in-process research
and development that had not yet reached technological feasibility and had no
alternative future use. Among the factors we considered in determining the
amount of the allocation of the purchase price to in-process research and
development the estimated stage of development of each module of the
technology, including the complexity and technical obstacles to overcome,
estimating the estimated expected life of each module, estimated cash flows
resulting from the expected revenues, margins, and operating expenses generated
from each module, and discounted the present value of cash flows associated
with the in-process technologies. Considering the inherent difficulty in
developing estimates of future performance for emerging technologies such as
the Millet Software applications, we utilized a relatively high rate of return
(30%) to discount to present value the cash flows associated with the in-
process technologies.

  Within the Millet Software technology there are three technologies, Form L,
Smart Mapper and Screen Walking. As of the date of acquisition, we estimated
that the Form L, Smart Mapper and Screen Walking technologies were 100%, 85%
and 65% completed, respectively. The percentage completed pre-acquisition for
each application was based primarily on the evaluation of two major factors:
time-based data and complexity-based data. The core technology reliance for the
Smart Mapper and Screen Walking technologies was 40% and 20%, respectively.

  We expect to fully integrate these technologies into our full suite of
Internet information infrastructure service offerings. Further, the modules
will not be distinguishable market segments for financial reporting purposes or
for management purposes. Consequently, there will be no separate and
distinguishable allocations or utilizations of net working capital, and no
specific charges for use of contributory assets. None of our operating expenses
are allocated to specific service offerings. The expected life of the modules
being developed was assumed to be five years, after which substantial
modification and enhancement would be required for the modules to remain
competitive.

  Our revenue assumptions for these modules were based on the subscription and
transaction revenue we expect to generate from our shopping services. Our
expense assumptions for these modules included cost of revenues, which we
estimated to be 3% of revenues as we will incur minimal costs to deliver this
technology

                                      105

on the platforms already developed and in use by us. Sales and marketing
expenses combined with general and administrative expenses were estimated to be
35% in the first two years, and thereafter to range between 30% to 35% as a
percentage of revenues. However, cost of revenues, sales and marketing expenses
and general and administrative expenses may vary, both in absolute dollars and
as a percentage of revenues.

  While we believe that the assumptions discussed above were made in good faith
and were reasonable when made, such assumptions remain largely untested, as the
three modules are not yet in service. Accordingly, the assumptions we made may
prove to be inaccurate, and there can be no assurance that we will realize the
revenues, gross profit, growth rates, expense levels or other variables set
forth in such assumptions.

  We do not expect to have the ability to calculate revenues specifically and
exclusively attributable to the integrated Millet technology. Further, the
absence of such attribution will not be material to any module's success. The
amount that we can charge customers for access and use of these modules will be
greatly influenced by market forces and competitor's pricing of their own
packaged and integrated offerings.

  Saraide Inc. On March 10, 2000 we acquired eighty percent of the common stock
of Saraide, a privately held company, for a purchase consideration of 9,233,672
shares and acquisition expenses of $340,489. The acquisition was accounted for
as a purchase in accordance with the provisions of APB No. 16.

  In this transaction, we assumed net liabilities of $16.2 million. The
purchase includes $97.0 million in purchased technology which includes in-
process research and development, $16.0 million of contract list, $2.1 million
of acquired workforce and $16.2 million in net liabilities.

  We issued shares with a fair value of $347.0 million and incurred acquisition
costs of $340,489. This resulted in $248.4 million of goodwill.

  We recorded a non-recurring charge of $71.7 million for in-process research
and development that had not yet reached technological feasibility and had no
alternative future use. Among the factors we considered in determining the
amount of the allocation of the purchase price to in-process research and
development were various factors such as estimating the stage of development of
each module of the technology, including the complexity and technical obstacles
to overcome, estimating the expected life of each module, estimating cash flows
resulting from the expected revenues, margins, and operating expenses generated
from each module, and discounting to present value the cash flows associated
with the in-process technologies.

  At the date of acquisition, Sariade had eight technologies which had not yet
reached technological feasibility: (1) asynchronous bridges, (2) lookup
service/persistent cache services, (3) transaction services, (4) open standards
application provider interface ("API"), (5) SS7 signaling functionality, (6)
security infrastructure, (7) location enabler, and (8) commerce enabler. With
the exception of the asynchronous bridges, all projects were estimated to be
commercially deployable in 2000. Once complete, these projects will provide the
fundamental operating system and infrastructure for the distributed networked
system platform ("DNSP"), Saraide's value added service platform under
development.

  The expected life of the modules being developed was assumed to be five to
seven years, after which substantial modification and enhancement would be
required for the modules to remain competitive.

  Our revenue assumptions for these modules were based on the number of
carriers in Europe and North America we estimated would utilize these services,
and the number of messages per month for Europe and the number of subscribers
per month for North America signed up with these carriers that would utilize
these services.

  Our expense assumptions for these modules included cost of revenues, which we
estimated to be 65% for 2000 and decreasing to 43% of revenues as we will incur
costs to deploy the technology globally.

                                      106
<PAGE>

Research and development costs were estimated to be 4.4% of revenues in 2000,
decreasing to 2.2%. Sales and marketing expenses combined with general and
administrative expenses were estimated to be 70% for 2000, and thereafter
decreasing to 20% as a percentage of revenues in line with industry levels as
the Company capitalizes on economies of scale. However, cost of revenues, sales
and marketing expenses and general and administrative expenses may vary, both
in absolute dollars and as a percentage of revenues.

  While we believe that the assumptions discussed above were made in good faith
and were reasonable when made, such assumptions remain largely untested, as the
technologies are in the process of being integrated and released with our full
suite of integrated Internet information infrastructure technologies and
services for wireless devices. Accordingly, the assumptions we made may prove
to be inaccurate, and there can be no assurance that we will realize the
revenues, gross profit, growth rates, expense levels or other variables set
forth in such assumptions. Considering the inherent difficulty in developing
estimates of future performance for emerging technologies such as the Saraide
technologies, we utilized a relatively high rate of return (35.0% to 37.5%) to
discount to present value the cash flows associated with the in-process
technologies.

  We do not expect to have the ability to calculate revenues specifically and
exclusively attributable to the integrated Saraide technology. Further, the
absence of such attribution will not be material to any module's success. The
amount that we can charge the wireless carriers and device manufacturers for
access and use of these modules will be greatly influenced by market forces and
by our competitor's pricing of their own packaged and integrated offerings.

  Prio, Inc. On February 14, 2000, we consummated the acquisition, pursuant to
an Agreement and Plan of Acquisition and Amalgamation, of Prio, a privately
held company. The combination was accounted for as a pooling of interests. We
issued 9,322,418 shares of our common stock in exchange for all the outstanding
common and preferred stock of Prio.

  Prio provides commerce solutions specializing in the development of strategic
partnerships, technologies and programs that drive commerce in both traditional
and online shopping environments and Internet commerce applications that
deliver solutions designed for small and medium-sized merchants to build,
manage and promote online storefronts. We have added these service offerings to
our merchant services. The consolidated financial statements and the
accompanying notes reflect our financial position and the results of operations
as if Prio was our wholly-owned subsidiary since inception.

  Zephyr Software Inc.: On December 29, 1999, we acquired all of the common
stock of Zephyr Software Inc., a privately held company, and its wholly owned
subsidiary Zephyr Software (India) Private Limited for a purchase consideration
of 651,392 shares of our common stock and acquisition expenses of $539,512. The
acquisition was accounted for as a purchase in accordance with Accounting
Principles Board ("APB") No. 16. Results of operations for Zephyr have been
included with our results of operations for the period subsequent to the date
of acquisition.

  In this transaction, we assumed net liabilities of $20,690, issued shares
with a fair value of $8,643,105 and incurred acquisition costs of $539,512.
This acquisition resulted in our recording $9,203,307 of goodwill.

  eComLive.com, Inc.: On December 16, 1999, we acquired all of the common stock
of eComLive.com, Inc., a privately held company, for a purchase consideration
of 1,372,712 shares and acquisition expenses of $582,246. The acquisition was
accounted for as a purchase in accordance with the provisions of APB No. 16.

  In this transaction, we assumed net assets of $5,439,075. This includes
$5,300,000 in purchased technology which includes in-process research and
development, $140,000 of acquired workforce and $925 in net liabilities. We
issued shares with a fair value of $31,995,220 and incurred acquisition costs
of $582,246. This acquisition resulted in our recording $27,138,391 of
goodwill.

                                      107
<PAGE>

  We recorded a non-recurring charge of $2.0 million for in-process research
and development that had not yet reached technological feasibility and had no
alternative future use.

  The eComLive technology is built on client-server architecture. There are
three main applications, Interactive eComLive for the Consumer to Consumer
(C2C) market, Business eComLive targeted to the Business to Business (B2B)
market and Consumer eComLive for the Business to Consumer (B2C) market. We have
the ability to integrate the C2C eComLive technology into the InfoSpace Web
site and launch this technology with our consumer services. We also plan to
offer a co-branded version to our affiliates as part of our suite of co-branded
service offerings. The expected life of the modules being developed was assumed
to be five years, after which substantial modification and enhancement would be
required for the modules to remain competitive.

  Union-Street: On October 14, 1999 we acquired all of the common stock of
Union-Street, a privately held company, for a purchase consideration of
1,746,588 shares and acquisition expenses of $395,656. The acquisition was
accounted for as a purchase in accordance with the provisions of APB No. 16.

  In this transaction, we assumed net assets of $5,352,781. This includes
$5,300,000 in purchased technology which includes in-process research and
development, $160,000 of acquired workforce and $107,219 in net liabilities. We
issued shares with a fair value of $20,487,518 and incurred acquisition costs
of $395,656. This acquisition resulted in our recording $15,530,393 of
goodwill.

  We recorded a non-recurring charge of $3.3 million for in-process research
and development that had not yet reached technological feasibility and had no
alternative future use.

  The Union-Street technology called Traction Series 3.0 is comprised of six
modules that promote inter-activity on the customer's Web site. Businesses can
integrate individual modules onto their sites or integrate all of the modules
to form a comprehensive community solution. The modules include (1) Web Site
Creator, (2) Event Manager, (3) Relationship Manager, (4) Forums, (5) Chat and
(6) Email. We have integrated most of the Union-Street technology into the
InfoSpace Web site and have launched the technology with our consumer services.
We also plan to offer a co-branded version to our affiliates as part of our
suite of co-branded service offerings. The expected life of the modules being
developed was assumed to be five years, after which substantial modification
and enhancement would be required for the modules to remain competitive.

  INEX Corporation: On October 14, 1999, we consummated an Agreement and Plan
of Acquisition and Amalgamation with INEX Corporation, a privately held
company. The combination was accounted for as a pooling of interests. We issued
3,600,000 shares of our common stock (1) directly to those INEX stockholders
who elected to receive our common stock in exchange for their INEX shares at
the closing of the combination, (2) upon the exchange or redemption of the
exchangeable shares of InfoSpace.com Canada Holdings Inc., an indirect
subsidiary of ours, which exchangeable shares were issued to those INEX
stockholders who elected to receive exchangeable shares, or who did not make an
election to receive shares of our common stock at the closing, and (3) upon the
exercise of outstanding warrants and options to purchase INEX common shares,
which we assumed and which will become exercisable for shares of our common
stock.

  INEX developed and marketed Internet commerce applications that deliver
solutions designed for small and medium-sized merchants to build, manage and
promote online storefronts. We have added these products to our merchant
services. The consolidated financial statements for the three years ended
December 31, 1999 and the accompanying notes reflect our financial position and
the results of operations as if INEX were our wholly-owned subsidiary since
inception.

  MyAgent(TM) Technology: On June 30, 1999, we acquired the MyAgent technology
and related assets from Active Voice Corporation for a cash payment of $18
million. In addition, we hired six employees who

                                      108
<PAGE>

comprised the MyAgent development team at Active Voice. The acquisition was
accounted for as a purchase in accordance with the provisions of APB No. 16.
Other than the MyAgent technology modules, no other assets or liabilities were
assumed as part of this acquisition.

  The total purchase price of the acquisition of the MyAgent technology was
$18.1 million including direct acquisition expenses of $83,054. In this
transaction, we assumed net assets of $4,380,000. This includes $4,300,000 in
purchased technology, which includes in-process research and development, and
$80,000 of acquired workforce. This acquisition resulted in our recording
$13,703,054 of goodwill.

  We recorded a non-recurring charge of $3.9 million for in-process research
and development that had not yet reached technological feasibility and had no
alternative future use. Separately, we recorded a one-time charge of $1.0
million for expenses related to bonus payments made to the Active Voice MyAgent
team employees who accepted employment with us on the date of the MyAgent
technology acquisition, but who have no obligation to continue their employment
with us.

  Within the MyAgent technology there are three main modules, the Client,
Server Intelligence, and Web Interface. We integrated the MyAgent technology
into the InfoSpace Web site and launched the technology with our desktop
portal. We also plan to offer a co-branded version to our affiliates as part of
our suite of co-branded service offerings. The Client and Server Intelligence
and Web interface were released in the fourth quarter of 1999.

  Technology from Outpost: In June 1998, we acquired Outpost, which included
the acquisition of the Outpost technology and the hiring of approximately ten
employees. In the second quarter of 1998, we wrote off approximately $2.8
million of in-process research and development in connection with the Outpost
acquisition.

  Within the acquired Outpost technology (smart-shopping services) there are
four main modules:

  . integrated content that provides users with product pricing and merchant
    information;

  . transaction proxy that allows us to track sales transactions from
    beginning to end and to receive confirmation reports from the retailers;

  . branding that allows users to travel to affiliate Web sites without
    leaving the InfoSpace.com Web site; and

  . universal shopping cart that allows users to make multiple purchases at
    different retailers in one execution.

  These modules have been integrated into our full suite of Internet service
offerings. The integrated content module was completed and integrated into our
Web site in the third quarter of 1998. Relevant portions of the transaction
proxy, branding and shopping cart modules were completed and integrated into
our ActiveShopper(TM) electronic commerce private label solution that was
launched in 1999.

  Our quarterly and annual revenue, expenses and operating results have
fluctuated in the past and are likely to fluctuate significantly in the future
due to a variety of factors, many of which are beyond our control. Because of
these fluctuations, we believe that period-to-period comparisons are not a good
indication of our future financial performance. We may not be able to sustain
or increase our level of revenue or our rate of revenue growth on a quarterly
or annual basis. Our quarterly or annual operating results may not meet the
expectations of investors. If this happens, the price of our stock could
decline. See "Risk Factors--Risks Relating to InfoSpace--Our financial results
are likely to fluctuate" and "Risk Factors--General Risks Related to the
Merger--InfoSpace's stock is volatile."

Recent Accounting Pronouncements

  In December 1999, the Securities and Exchange Commission staff issued Staff
Accounting Bulletin (SAB) 101, Revenue Recognition in Financial Statements. We
adopted SAB 101 on January 1, 2000. Prior to January 1, 2000 and implementation
of the SAB, we recorded gross revenues from customers for development fees,
implementation fees and/or integration fees when the service was completed. If
this revenue were recognized on a straight-line basis, in accordance with SAB
101, we would have deferred $719,216 as of January 1, 2000. In accordance with
SAB 101, we recorded a cumulative effect of change in accounting principle of
$719,216. We recorded $367,896 in revenue in the six months ended June 30, 2000
related to this deferred revenue. The remaining balance will be recognized from
July 2000 through November 2001.

  In June 1998, the FASB issued SFAS No. 133, Accounting for Derivatives and
Hedging Activities. SFAS 133, as amended by SFAS 137, establishes accounting
and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. Because the Company has never used
nor currently intends to use derivatives, management does not anticipate that
the adoption of this new standard will have a significant effect on earnings or
the financial position of the Company.

Quantitative and Qualitative Disclosures About Market Risk

  We are exposed to financial market risks, including changes in interest rates
and equity price fluctuations.

  Interest Rate Risk: We invest our excess cash in high-quality corporate
issuers, and in debt instruments of the U.S. Government and its agencies. By
policy, we limit our credit exposure to any one issuer. We do not have any
derivative instruments in our investment portfolio. We protect and preserve
invested funds by limiting default, market and reinvestment risk. Investment in
both fixed rate and floating rate interest earning instruments carries a degree
of interest rate risk. Fixed rate securities may have their fair market value
adversely impacted due to a rise in interest rates, while floating rate
securities may produce less income than expected if interest rates fall. Due in
part to these factors, the Company's future investment income may fall short of
expectations due to changes in interest rates or the Company may suffer losses
in principal if forced to sell securities which have declined in market value
due to changes in interest rates.

  Equity Investment Risk The Company invests in equity instruments of public
and privately-held technology companies for business and strategic purposes.
These investments are recorded as long-term assets and are classified as
available-for-sale. For the privately-held investments, our policy is to
regularly review the assumptions underlying the operating performance and cash
flow forecasts in assessing the carrying value. For our publicly-held
investments, we are subject to significant fluctuations in fair market value
due to the volatility of the stock market. Changes in fair market value are
recorded as a component of other comprehensive income and do not effect net
income until the securities are sold and a realized gain or loss is incurred.

Compensation Committee reviews and approves the compensation and benefits for
our executive officers, administers our Stock Incentive Plan and makes
recommendations to the board of directors regarding such matters.

  The Audit Committee consists of Messrs. Currie, House and Stork. Among other
functions, the Audit Committee makes recommendations to our board of directors
regarding the selection of independent auditors, reviews the results and scope
of the audit and other services provided by our independent auditors, reviews
our balance sheet, statement of operations and cash flows and reviews and
evaluates our internal control functions.

Compensation Committee Interlocks and Insider Participation

  No member of our board of directors or of the Compensation Committee serves
as a member of the board of directors or compensation committee of any entity
that has one or more executive officers serving as a member of our board of
directors or Compensation Committee.

Director Compensation

  We pay directors $750 for each board of directors meeting attended in person,
$500 for each board of directors meeting attended by telephone and $500 for
each committee meeting attended. We also reimburse directors for travel
expenses incurred to attend meetings of the board of directors or committee
meetings.

Directors are eligible to participate in the Stock Incentive Plan. See "--
Benefit Plans--Stock Option Program for Nonemployee Directors."

Limitation of Liability and Indemnification Matters

  Our Restated Certificate of Incorporation limits the liability of our
directors to the fullest extent permitted by Delaware law. Delaware law
provides that a corporation's certificate of incorporation may contain a
provision eliminating or limiting the personal liability of directors for
monetary damages for breach of their fiduciary duties as directors, except for
liability:

  . for any breach of their duty of loyalty to the corporation or its
    stockholders;

  . for acts or omissions not in good faith or which involve intentional
    misconduct or a knowing violation of law;

  . for unlawful payments of dividends or unlawful stock repurchases or
    redemptions as provided in Section 174 of the Delaware General
    Corporation Law; or

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

  Our Restated Bylaws provide that we shall indemnify our directors and
officers and may indemnify our employees and agents to the fullest extent
permitted by law. We believe that indemnification under our Restated Bylaws
covers at least negligence and gross negligence on the part of indemnified
parties. We have also entered into agreements to indemnify our directors and
executive officers. Pursuant to these agreements, among other things, we have
agreed to indemnify our directors and officers for certain expenses (including
attorneys' fees), judgments, fines and settlement amounts incurred by them in
any action or proceeding arising out of their services as a director or
officer. We believe that these agreements are necessary to attract and retain
qualified directors and officers.

  On December 11, 1998, InfoSpace, all of our directors and Naveen Jain, our
Chief Executive Officer at the time, entered into an Indemnification Agreement
whereby Mr. Jain placed 8,000,000 shares of our common stock beneficially owned
by him in an escrow account to indemnify us and our directors for certain known
and unknown liabilities that may have arisen prior to September 30, 1998. See "
InfoSpace Business--Legal Proceedings."

Compensation of Executive Officers

  The following table sets forth information concerning the compensation we
paid to Naveen Jain, our chief executive officer, and the three other executive
officers of InfoSpace as of December 31, 1999 who earned compensation in excess
of $100,000 during 1999 (collectively, the "Named Executive Officers").

Employment Agreement

  We entered into an employment agreement dated as of December 16, 1999 with
Bernee D.L. Strom, pursuant to which Ms. Strom served as InfoSpace's President
and Chief Operating Officer through December 31, 1999, and as President of our
venture capital division from January 1, 2000 through June 30, 2000. This
employment agreement superseded a prior employment agreement with Ms. Strom
entered into in December 1998. Among other things, the employment agreement
provided that we would continue to provide Ms. Strom with salary and benefits
equal to those granted under her prior employment agreement, including an
annual salary of $250,000 and insurance and other employee benefits and option
grants previously made to Ms. Strom pursuant to her prior employment agreement
through June 30, 2000. In addition, the employment agreement provided for a
severance payment of $250,000 to Ms. Strom on June 30, 2000 and, under certain
circumstances, reimbursement of certain expenses incurred by Ms. Strom in
connection with her relocation to the Seattle, Washington area.

  In connection with this employment agreement, we loaned Ms. Strom $10 million
for her exercise of stock options and payment of federal taxes thereon. The
loan is due and payable on December 16, 2001 and accrues interest at the prime
rate.

Benefit Plans

  The following is a brief summary of plans in effect during 1999 under which
our executive officers and directors received benefits:

 Restated 1996 Flexible Stock Incentive Plan

  The purpose of the Stock Incentive Plan is to provide an opportunity for our
employees, officers, directors, independent contractors and consultants to
acquire our common stock. The Stock Incentive Plan provides for grants of stock
options, stock appreciation rights, or SARs, and stock awards. We have
authorized an aggregate of 45,967,866 shares of common stock for issuance under
the Stock Incentive Plan. As of June 30, 2000, options to purchase 25,510,699
shares of common stock were outstanding under the Stock Incentive Plan at a
weighted average exercise price of $29.0398 per share, and options to purchase
11,334,009 shares were available for future grant.

 Stock Option Program for Nonemployee Directors

  Under the Stock Incentive Plan, we grant a nonqualified stock option to
purchase 20,000 shares of common stock to each nonemployee director on the date
the director is first appointed or elected to our board of directors.
Nonemployee directors serving at the time of the adoption of the program each
received an option to purchase 5,000 shares of common stock. On November 19,
1998, each nonemployee director received a supplemental option to purchase
80,000 shares of common stock. We grant to each nonemployee director an
additional nonqualified stock option to purchase 15,000 shares of common stock
immediately following each Annual Meeting of Stockholders, except for those
nonemployee directors who were newly elected to the board of directors at such
Annual Meeting of Stockholders or within the three-month period prior to such
Annual Meeting of Stockholders. All options granted under the program for
nonemployee directors fully vest on the first anniversary of the date of such
grant.

 1998 Employee Stock Purchase Plan

  We adopted the 1998 Employee Stock Purchase Plan in August 1998. The Purchase
Plan is intended to qualify under Section 423 of the Code and permits eligible
employees to purchase our common stock through payroll deductions of up to 15%
of their compensation. Under the Purchase Plan, no employee may purchase stock
worth more than $25,000 in any calendar year, valued as of the first day of
each offering period. We have authorized an aggregate of 3,600,000 shares of
common stock for issuance under the Purchase Plan.

                                      118
<PAGE>

  The Purchase Plan is implemented with six-month offering periods. Offering
periods begin on each February 1 and August 1. Participants purchase common
stock under the Purchase Plan at a price equal to the lesser of 85% of their
fair market value on the first day of an offering period and 85% of the fair
market value on the last day of an offering period. As of June 30, 2000,
189,278 shares of common stock have been issued under the Purchase Plan.

 InfoSpace, Inc. and Saraide Inc. 2000 Stock Plan

  InfoSpace, Inc. and Saraide each adopted the 2000 Stock Plan effective April
17, 2000. The purpose of the 2000 Stock Plan is to attract, retain and provide
incentives to employees, directors and consultants of Saraide. The 2000 Stock
Plan provides for grants of both Saraide options and InfoSpace options;
optionees will have the right to exercise either set of options as they vest.
When an optionee exercises a number of Saraide options, this will automatically
cancel a proportional number of the optionee's InfoSpace options, and
similarly, when an optionee exercises a number of InfoSpace options, this will
automatically cancel a proportional number of the optionee's Saraide options.
InfoSpace has authorized an aggregate of 10,000,000 shares of InfoSpace common
stock for issuance under the 2000 Stock Plan, and Saraide has authorized an
aggregate of 10,000,000 shares of Saraide common stock for issuance under the
2000 Stock Plan.

  As of June 30, 2000, options to purchase 6,528,700 shares of InfoSpace common
stock were outstanding under the 2000 Stock Plan at a weighted average exercise
price of $45.4375 per share, and options to purchase 3,471,300 shares of
InfoSpace common stock were available for future grant.

                  INFOSPACE TRANSACTIONS WITH RELATED PARTIES

  In this section, InfoSpace Transactions with Related Parties, references to
"we," "us," "our" and "ours" refer to InfoSpace and its consolidated
subsidiaries.

  Acorn Ventures-IS, LLC and John E. and Carolyn Cunningham are entitled to
certain registration rights with respect to the shares of our common stock and
our common stock issuable upon exercise of warrants purchased in private
placements completed in 1998. Rufus W. Lumry, III, one of our directors, is the
principal stockholder, sole director and president of Acorn Ventures, Inc., the
sole member of Acorn Ventures-IS, LLC. John E. Cunningham is also one of our
directors.

  On May 21, 1998, we entered into Consulting Agreements with Acorn Ventures
and John E. Cunningham, IV, pursuant to which we are required to pay reasonable
out-of-pocket expenses incurred by them in connection with their services as
consultants. In addition, we have entered into agreements to indemnify Acorn
Ventures-IS, LLC and John E. Cunningham, IV against expenses (including
attorneys' fees), judgments, fines and settlement amounts incurred by them in
any action or proceeding in which they are parties or participants arising out
of their services as consultants. These consulting services include assistance
in defining our business strategy, identifying and meeting with sources of
financing and assisting us in structuring and negotiating such financings. The
Consulting Agreements have terms of five years and are terminable by either
party upon breach of the Consulting Agreement by the other party or on 30 days'
notice. Other than the reimbursement of out-of-pocket expenses, there is no
cash compensation due under the Consulting Agreements. We anticipate that the
Consulting Agreements will be terminated in the third quarter of 2000.

  In July 1998, we entered into a joint venture agreement with TDLI.com
Limited, a subsidiary of Thomson Directories Limited, to form TDL InfoSpace to
replicate our infrastructure services in Europe. TDL InfoSpace has been
providing content services in the United Kingdom since the third quarter of
1998. Under the Web site services agreement, Thomson provides its directory
information to TDL InfoSpace and sells Internet yellow pages advertising for
the joint venture through its local sales forces. We also license our
technology and provide hosting services to TDL InfoSpace. Thomson and InfoSpace
each purchased a 50% interest in TDL InfoSpace and are required to provide
reasonable working capital to TDL InfoSpace. As of December 31, 1999, we had
contributed $496,000 to the joint venture. Gary C. List, formerly one of our
directors, is Chairman of Thomson Directories Limited and Chief Executive of
its parent company, TDL Group Limited. On July 26, 2000, we entered into a
definitive agreement to acquire all of the issued and outstanding stock of
TDLI.com Limited. This will give us complete control of TDL InfoSpace.

  In January 2000, we entered into contracts to provide content and promotional
services to ImageX.com, Inc., pursuant to which we may earn up to $1.2 million
in fees over a one-year period. Rufus W. Lumry, III, one of our directors, is
President of Acorn Ventures, Inc., which directly and through affiliated
entities beneficially owns over 12% of the common stock of ImageX.com, Inc. as
of February 29, 2000 (based on information filed with the SEC by ImageX.com,
Inc.).

  During 1999, we entered into a technology license and development agreement
for the development of online shopping cart technology with TEOCO Corporation.
Under the terms of the agreement, we paid a development fee to TEOCO
Corporation of $400,000. We own all rights to the technology and have granted a
perpetual license to TEOCO Corporation to use the developed technology for
certain limited uses. Atul Jain, the President and majority stockholder of
TEOCO Corporation, is the brother of Naveen Jain, our Chairman.

  We believe that all the transactions set forth above were made on terms no
less favorable to us than could have been obtained from unaffiliated third
parties. Any future transactions, including loans, between us and our officers,
directors and principal stockholders and their affiliates will be approved by a
majority of

                                      122
<PAGE>

the board of directors, including a majority of the independent and
disinterested directors, and will be on terms no less favorable to us than
could be obtained from unaffiliated third parties.

  We have entered into indemnification agreements with each of our executive
officers and directors.

  On December 11, 1998, we, all of our current and future directors and Naveen
Jain entered into an Indemnification Agreement whereby Mr. Jain placed
8,000,000 shares of our common stock beneficially owned by him into an escrow
account to indemnify us and our directors for a period of five years for
certain known and unknown liabilities that may have arisen prior to September
30, 1998. The indemnification agreement, however, did not provide for
indemnification for certain matters known by the Board prior to September 30,
1998 or losses less than $100,000. On February 10, 2000, in exchange for the
release of such shares, Mr. Jain entered in a Noncompetition Agreement with us.
In addition to noncompetition, nondisclosure and invention release provisions
which apply during his employment, the Noncompetition Agreement also provides
that Mr. Jain will not engage in activities which compete with our business
during the two years after termination of his employment with us for any
reason.

  In connection with our Employment Agreement dated as of December 16, 1999
with Bernee D. L. Strom, we loaned $10 million to Ms. Strom for the purpose of
exercising stock options and paying federal taxes thereon. The loan will be due
and payable two years from the date of the Employment Agreement, and accrues
interest at the prime rate. The largest amount outstanding since the date of
the Employment Agreement was $10 million, which was the outstanding balance of
the loan as of June 30, 2000. For a further description of the Employment
Agreement, see "InfoSpace Management--Employment Agreement."

(1) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission. In computing the number of shares
    beneficially owned by a person and the percentage ownership of that person,
    shares of common stock subject to options held by that person that are
    currently exercisable, or become exercisable within 60 days from August 28,
    2000, are deemed outstanding. However, such shares are not deemed
    outstanding for purposes of computing the percentage ownership of any other
    person. Percentage ownership is based on 40,464,956 shares of common stock
    outstanding as of August 28, 2000 which includes shares of Series A

         UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS

Overview

  On July 26, 2000, InfoSpace entered into an agreement to merge with Go2Net in
a transaction which is intended to be accounted for under the pooling-of-
interests method of accounting. The terms of the merger agreement require
InfoSpace to issue 1.82 shares of InfoSpace common stock for each share of
Go2Net common stock share outstanding as of the effective date of the merger.

  The accompanying unaudited pro forma combined consolidated balance sheets as
of fiscal year end 1999 and June 30, 2000, assumes that the merger took place
as of the earliest date presented. The unaudited pro forma combined
consolidated balance sheets combine the unaudited consolidated balance sheet of
InfoSpace as of December 31, 1999 and June 30, 2000 and the unaudited
consolidated balance sheets of Go2Net as of September 30, 1999 and June 30,
2000.

  The accompanying unaudited pro forma combined consolidated statements of
operations present the results of operations of InfoSpace for: (i) the six
months ended June 30, 2000 combined with the consolidated statement of
operations for Go2Net for the six months ended June 30, 2000; (ii) the six
months ended June 30, 1999, combined with the consolidated statement of
operations for Go2Net for the six months ended June 30, 1999; (iii) the year
ended December 31, 1999, combined with the consolidated statement of operations
for Go2Net for the fiscal year ended September 30, 1999; (iv) the year ended
December 31, 1998, combined with the consolidated statement of operations for
Go2Net for the fiscal year ended September 30, 1998; and (v) the year ended
December 31, 1997, combined with the consolidated statement of operations for
Go2Net for the fiscal year ended September 30, 1997. The unaudited pro forma
combined consolidated statements of operations give effect to the merger as if
it had occurred as of the earliest period presented.

  The unaudited pro forma combined consolidated balance sheet and statements of
operations are not necessarily indicative of the financial position and
operating results that would have been achieved had the transaction been in
effect as of the dates indicated and should not be construed as being a
representation of financial position or future operating results of the
combined companies.

  The unaudited pro forma combined consolidated financial information should be
read in conjunction with the audited consolidated financial statements and
related notes of InfoSpace and Go2Net which are included elsewhere in this
registration statement.

                       CONSOLIDATED FINANCIAL STATEMENTS

1. The Periods Combined

  The InfoSpace, Inc. consolidated balance sheets as of December 31, 1999 and
June 30, 2000 have been combined with the Go2Net, Inc. consolidated balance
sheets as of September 30, 1999 and June 30, 2000.

  The InfoSpace, Inc. consolidated statements of operations for the years ended
December 31, 1997, 1998 and 1999 and for the six months ended June 30, 1999 and
2000 have been combined with the Go2Net, Inc. statements of operations for the
periods from October 1, 1996 to September 30, 1997, October 1, 1997 to
September 30, 1998, October 1, 1998 to September 30, 1999 and the six months
ended June 30, 1999 and 2000, as if the merger had occurred as of the beginning
of the period. Go2Net reported results on a fiscal year ending September 30.

  InfoSpace has a fiscal year end of December 31, and Go2Net has a fiscal year
end of September 30. The unaudited pro forma statements of operation for the
fiscal years ended 1999, 1998 and 1997 combine the different fiscal year ends.
The unaudited pro forma statements of operation for the six months ended
June 30, 2000 and 1999, present the combined information for the six months
ended June 30, 2000 and 1999. As such, the statement of operations of Go2Net
for the first quarter of fiscal year end September 30, 2000 is not presented.
Go2Net had revenues of $14.0 million and a net loss of $11.3 million for the
first quarter of fiscal year ended September 30, 2000.

2. Pro Forma Basis of Presentation

  The pro forma adjustments made in connection with the development of the pro
forma information have been made solely for purposes of developing such pro
forma information as necessary to comply with the disclosure requirements of
the Securities and Exchange Commission. The Unaudited Pro Forma Combined
Consolidated Financial Statements do not purport to be indicative of the
combined financial position or results of operations of future periods or
indicative of the results of operations of future periods or indicative of the
results that actually would have been realized had the entities been a single
entity during these periods.

  The Unaudited Pro Forma Combined Financial Statements reflect the issuance of
shares of InfoSpace, Inc. common stock in exchange for all of the outstanding
stock, warrants, and options of Go2Net, Inc. InfoSpace will issue 1.82 shares
of InfoSpace common stock for each share of Go2Net Common Stock. The pro forma
adjustments reflect the additional shares that would be used in computing basic
and diluted earnings per share as if the merger had occurred at the earliest
period presented.

3. Pro Forma Earnings Per Share

  The Unaudited Pro Forma Combined Consolidated Financial Statements for
InfoSpace, Inc. have been prepared as if the merger was completed at the
earliest periods presented. The pro forma basic net loss per share is based on
the combined weighted average number of shares of InfoSpace, Inc. Common Stock
outstanding during the period and the number of InfoSpace, Inc. Common Stock to
be issued in exchange as discussed in Note 2.

  The Pro Forma diluted loss per share is computed using the weighted average
number of InfoSpace, Inc. common stock and dilutive common equivalent shares
outstanding during the period and the number of shares of InfoSpace, Inc.
common stock to be issued in exchange. Common equivalent shares consist of the
incremental common shares issuable upon conversion of the exercise of stock
options and warrants using the treasury stock method. Common equivalent shares
are excluded from the computation if their effect is

antidilutive. The combined Company had a pro forma net loss for all periods
presented herein; therefore, none of the options and warrants outstanding
during each of the periods presented were included in the computation of pro
forma dilutive earnings per share as they were antidilutive.

4. Pro Forma Adjustments

  The objective of the pro forma information is to show what the significant
effects on the historical financial information might have been had the
Companies been merged for the periods presented. The Pro Forma adjustments are
preliminary and based on management's best estimates.

  Pro Forma Adjustment represents the issuance of 1.82 shares of InfoSpace,
Inc. Common Stock in exchange for each share of Go2Net, Inc. including shares
issued and outstanding, vested warrants and vested stock options. The pro forma
adjustments reflect the additional shares that would be used in computing basic
and diluted earnings per share as if the Merger had occurred at the beginning
of each period.

  Pro Forma adjustments include certain reclassifications to conform to
combined presentation.

  Go2Net had reflected a tax benefit of approximately $715,000 in the fiscal
year ending September 30, 1999. On a combined basis this benefit would not be
realized as the combined company does not project sufficient taxable income
with which to realize this benefit. A Pro Forma adjustment was recorded to
reverse this $715,000 benefit.

  All intercompany transactions between InfoSpace, Inc. and Go2Net, Inc. have
been eliminated for all periods presented.

  Pro Forma adjustments reflect the conversion of 300,000 shares of preferred
stock converted to common stock of Go2Net, Inc. at a conversion ratio 30.2526.
These shares are adjusted for the exchange of 1.82 shares of InfoSpace, Inc.
common stock.

                     DESCRIPTION OF INFOSPACE CAPITAL STOCK

  Our authorized capital stock consists of 900,000,000 shares of common stock,
$0.0001 par value per share, and 15,000,000 shares of preferred stock, $0.0001
par value per share. The following summary of certain provisions of our common
stock and preferred stock does not purport to be complete and is subject to,
and qualified in its entirety by reference to, the provisions of our
certificate of incorporation and by the applicable provisions of Delaware law.

Common Stock

  As of August 28, 2000, there were 233,598,517 shares of our common stock
outstanding held by approximately 813 holders of record.

  The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders. There are no
cumulative voting rights. Subject to preferences that may be applicable to any
outstanding shares of preferred stock, the holders of common stock are entitled
to receive ratably such dividends, if any, as may be declared by the board of
directors out of funds legally available for the payment of dividends. In the
event of a liquidation, dissolution or winding up of InfoSpace, the holders of
common stock are entitled to share ratably in all assets remaining after
payment of liabilities and liquidation preferences of any outstanding shares of
preferred stock. Holders of common stock have no preemptive rights or rights to
convert their common stock into any other securities. There are no redemption
or sinking fund provisions applicable to the common stock. All outstanding
shares of common stock are fully paid and nonassessable, and the shares of
common stock to be issued upon completion of this offering will be fully paid
and nonassessable. See "Risk Factors--Risks Relating to InfoSpace--Management
owns a large percentage of our stock" and "Market Price and Dividend
Information--Dividends."

Preferred Stock

  Pursuant to our Certificate of Incorporation, our board of directors has the
authority, without further action by our stockholders, to issue up to
15,000,000 shares of preferred stock in one or more series and to fix the
designations, powers, preferences, privileges and relative, participating,
optional or special rights and the qualifications, limitations or restrictions
thereof, including dividend rights, conversion rights, voting rights, terms of
redemption and liquidation preferences, any or all of which may be greater than
the rights of the common stock. Our board of directors, without stockholder
approval, can issue preferred stock with voting, conversion or other rights
that could adversely affect the voting power and other rights of the holders of
common stock. Preferred stock could thus be issued quickly with terms
calculated to delay or prevent a change of control or make removal of
management more difficult. Additionally, the issuance of preferred stock may
have the effect of decreasing the market price of the common stock, and may
adversely affect the voting and other rights of the holders of common stock.

Voting Share

  A single share of series A preferred stock, the voting share, was issued in
connection with the INEX Corporation acquisition and the voting and exchange
trust agreement entered into by and among InfoSpace, InfoSpace.com Canada
Holdings and Montreal Trust Company of Canada. The voting share was issued to
Montreal Trust Company of Canada, as trustee, to hold for the benefit of the
holders of exchangeable shares that were issued by an indirect subsidiary of
InfoSpace to complete this transaction. The trustee is entitled to the number
of votes equal to the number of votes the holders of the outstanding
exchangeable shares, not held directly or indirectly by InfoSpace or its
subsidiaries, would be entitled to if the exchangeable shares were exchanged
for shares of InfoSpace's common stock. As of August 28, 2000, there were
846,570 outstanding exchangeable shares not held by InfoSpace or its
subsidiaries, which gives the trustee 846,570 votes to exercise on behalf of
the exchangeable shareholders.

  The holders of the exchangeable shares have the right to require
InfoSpace.com Canada Holdings to redeem any or all of their exchangeable shares
for an amount per share equal to the current market price of

                                      137
<PAGE>

one share of InfoSpace common stock, which shall be paid in full by delivering
one share of InfoSpace common stock for each exchangeable share presented to be
redeemed. The certificate of the powers, designation, preferences and rights of
the series A preferred stock provide that the voting share and the common stock
shall vote together as a single class.

  The voting share will not entitle the trustee to receive dividends. In the
event of our dissolution, liquidation or the winding up of our affairs, the
trustee will receive an amount equal to $1.00, together with payment to any
class of stock ranking equally with the Series A preferred and before payment
shall be made to the holders of stock ranking junior. This amount will be
adjusted to reflect the effect of any stock split, stock dividend, combination
or similar change on the voting share. When there are no longer any outstanding
exchangeable shares other than those exchangeable shares which are held by us
or our subsidiaries, the voting share will cease to have any rights. In such
event, we will redeem the voting share for an amount equal to the par value of
the voting share and it will automatically return to being an authorized but
unissued share of our preferred stock. There are no sinking fund provisions or
preemptive rights applicable to the voting share.

Warrants

  As of August 31, 2000, there were outstanding warrants to purchase 18,866,056
shares of our common stock. Two investors hold warrants to purchase an
aggregate of 13,673,584 and 242,880 shares of common stock, which expire on May
21, 2008 and August 6, 2008, respectively, at a weighted average exercise price
of $0.73 per share. On August 24, 1998, in connection with the agreement
relating to our white pages directory services, we issued to AOL warrants to
purchase up to 7,919,328 shares of common stock, which warrants vest in 16
equal quarterly installments over four years, based on the delivery by AOL of a
minimum number of searches on our white pages directory service. As of August
31, 2000, AOL had 4,949,592 outstanding warrants. The warrants have an exercise
price of $1.50 per share.

  Upon consummation of our combination with INEX, we assumed warrants that are
exercisable for approximately 288,808 shares of our common stock.

Antitakeover Effects of Certain Provisions of Certificate of Incorporation and
Washington and Delaware Law; Right of First Negotiation

  As noted above, our board of directors, without stockholder approval, has the
authority under our Certificate of Incorporation to issue preferred stock with
rights superior to the rights of the holders of common stock. As a result, we
could issue preferred stock quickly and easily, which could adversely affect
the rights of holders of common stock and could be issued with terms calculated
to delay or prevent a change of control or make removal of management more
difficult.

  Election and Removal of Directors. Our bylaws provide for the division of our
board of directors into three classes, as nearly equal in number as possible,
with the directors in each class serving for a three-year term, and one class
being elected each year by our stockholders. See "InfoSpace Management--board
of directors." Directors may be removed only for cause. This system of electing
and removing directors may tend to discourage a third party from making a
tender offer or otherwise attempting to obtain control of InfoSpace and may
maintain the incumbency of the board of directors, as it generally makes it
more difficult for stockholders to replace a majority of directors.

  Approval of Certain Business Combinations. Our certificate of incorporation
requires that certain business combinations (including a merger, share exchange
and the sale, lease, exchange, mortgage, pledge, transfer or other disposition
or encumbrance of a substantial part of our assets other than in the usual and
regular course of business) be approved by the holders of not less than two-
thirds of the outstanding shares, unless such business combination has been
approved by a majority of the board of directors, in which case the affirmative
vote required shall be a majority of the outstanding shares.

                                      138
<PAGE>

  Stockholder Meetings. Under our certificate of incorporation and bylaws, our
stockholders may call a special meeting only upon the request of holders of at
least 30% of our outstanding shares. Additionally, our board of directors,
Chairman of the Board or our President may call special meetings of
stockholders.

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

  Washington Statute. The laws of Washington, where our principal executive
offices are located, impose restrictions on certain transactions between
certain foreign corporations and significant stockholders. Chapter 23B.19 of
the Washington Business Corporation Act, or the WBCA, prohibits a "Target
Corporation," with certain exceptions, from engaging in certain "Significant
Business Transactions" with a person or group of persons which beneficially
owns 10% or more of the voting securities of the Target Corporation (an
"Acquiring Person") for a period of five years after such acquisition, unless
the transaction or acquisition of shares is approved by a majority of the
members of the Target Corporation's board of directors prior to the time of
acquisition. Such prohibited transactions include, among other things, a merger
or consolidation with, disposition of assets to, or issuance or redemption of
stock to or from, the Acquiring Person, termination of 5% or more of the
employees of the Target Corporation as a result of the Acquiring Person's
acquisition of 10% or more of the shares or allowing the Acquiring Person to
receive any disproportionate benefit as a stockholder. After the five-year
period, a Significant Business Transaction may take place as long as it
complies with certain fair price provisions of the statute or is approved at an
annual or special meeting of stockholders.

  A Target Corporation includes a foreign corporation if:

   . the corporation has a class of voting stock registered pursuant to
     Section 12 or 15 of the Securities Exchange Act of 1934;

   . the corporation's principal executive office is located in Washington;

   . any of:

    . more than 10% of the corporation's stockholders of record are
      Washington residents;

    . more than 10% of its shares of record are owned by Washington
      residents; or

    . 1,000 or more of its stockholders of record are Washington residents;

   . a majority of the corporation's employees are Washington residents or
     more than 1,000 Washington residents are employees of the corporation;
     and

   . a majority of the corporation's tangible assets are located in
     Washington or the corporation has more than $50 million of tangible
     assets located in Washington.

  A corporation may not "opt out" of this statute. If we meet the definition of
a Target Corporation, Chapter 23B.19 of the WBCA may have the effect of
delaying, deferring or preventing a change of control of InfoSpace.

  Delaware Statute. We are subject to Section 203 of the Delaware General
Corporation law, which prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless:

  . prior to such date, the board of directors of the corporation approves
    either the business combination or the transaction that resulted in the
    stockholder's becoming an interested stockholder;

                                      139
<PAGE>

  . upon consummation of the transaction that resulted in the stockholder's
    becoming an interested stockholder, the interested stockholder owns at
    least 85% of the outstanding voting stock, excluding shares held by
    directors, officers and certain employee stock plans; or

  . on or after the consummation date the business combination is approved by
    the board of directors and by the affirmative vote at an annual or
    special meeting of stockholders of at least two-thirds of the outstanding
    voting stock that is not owned by the interested stockholder.

  For purposes of Section 203, a "business combination" includes, among other
things, a merger, asset sale or other transaction resulting in a financial
benefit to the interested stockholder, and an "interested stockholder" is
generally a person who, together with affiliates and associates of such person:

  . owns 15% or more of the corporation's voting stock; or

  . is an affiliate or associate of the corporation and was the owner of 15%
    or more of the outstanding voting stock of the corporation at any time
    within the prior three years.

  AOL Agreement. Pursuant to certain agreements with AOL, if we receive an
unsolicited proposal, or we determine to solicit proposals or otherwise enter
into discussions that would result in a sale of a controlling interest in
InfoSpace or other merger, asset sale or other disposition that effectively
results in a change of control (a "Disposition"), then we are required to give
written notice to AOL, and AOL has seven days to provide notice to us of its
desire to negotiate in good faith with us regarding a Disposition involving
AOL. In the event that AOL timely delivers such a notice, then we must
negotiate exclusively and in good faith with AOL regarding a Disposition for a
period of 30 days from the date of delivery of our initial notice to AOL, after
which we will be free to negotiate a Disposition with other third parties if we
and AOL cannot in good faith come to terms. If such a Disposition is not
consummated within five months from the date of delivery of our initial notice
to AOL, the process described above will again apply. AOL's right of first
negotiation could have the effect of delaying, deterring or preventing a change
of control.

  These charter provisions, provisions of Washington and Delaware law and AOL's
right of first negotiation may have the effect of delaying, deterring or
preventing a change of control.

                        COMPARISON OF STOCKHOLDER RIGHTS
                        AND CORPORATE GOVERNANCE MATTERS

  This section of the joint proxy statement/prospectus describes the material
differences between the rights of holders of Go2Net common stock and holders of
InfoSpace common stock. While InfoSpace and Go2Net believe that the description
covers the material differences between the two, this summary may not contain
all of the information that is important to you. This summary is not intended
to be a complete discussion of the respective certificates of incorporation and
bylaws of InfoSpace and Go2Net and it is qualified in its entirety to
applicable Delaware law as well as to InfoSpace's and Go2Net's respective
certificates of incorporation and bylaws. You should carefully read this entire
summary and the other documents we refer to for a more complete understanding
of the differences between being a stockholder of Go2Net and being a
stockholder of InfoSpace. InfoSpace's and Go2Net's respective certificates of
incorporation and bylaws are on file with the SEC and will also be sent to you
upon request. See "Where You Can Find More Information."

  Both InfoSpace and Go2Net are incorporated under the laws of the State of
Delaware. Accordingly the rights of their stockholders are governed by Delaware
law and by their respective certificates of incorporation and bylaws. If the
merger is completed, stockholders of Go2Net will become stockholders of
InfoSpace and the rights of such former stockholders of Go2Net will be governed
by Delaware law, the InfoSpace certificate of incorporation and the InfoSpace
bylaws. The following summarizes differences in the charter documents of Go2Net
and InfoSpace that could materially affect the rights of stockholders of Go2Net
after completion of the merger. A number of the provisions of InfoSpace's
charter documents may have the effect of delaying, deferring or preventing a
future change in control of InfoSpace.

           SUMMARY OF MATERIAL DIFFERENCES BETWEEN CURRENT RIGHTS OF
         GO2NET STOCKHOLDERS AND RIGHTS THOSE STOCKHOLDERS WILL HAVE AS
                  INFOSPACE STOCKHOLDERS FOLLOWING THE MERGER

April 30, 2001. Proposals of InfoSpace stockholders intended to be presented
for consideration at the InfoSpace 2001 annual meeting of stockholders must be
received by InfoSpace no later than December 26, 2000, in order that they may
be included in the proxy statement and form of proxy relating to that meeting.

  Although it is expected that the closing of the merger with InfoSpace will
occur promptly after the stockholders' special meetings, in the event the
closing of the merger is delayed, and Go2Net is required to hold an annual
meeting in 2001, it is expected that such annual meeting will be held on or
about March 15, 2001. In such event, stockholder proposals for inclusion in the
proxy material for Go2Net's 2001 annual meeting of stockholders should be
submitted to the secretary of Go2Net in writing and received at the executive
offices of Go2Net on or about October 7, 2000. Such proposals must also have
met the other requirements of the rules of the Securities and Exchange
Commission relating to stockholder proposals and must have satisfied the notice
procedures for stockholder proposals set forth in the Go2Net bylaws. If Go2Net
is not notified of a stockholder proposal by December 21, 2000, then proxies
held by management of Go2Net provide discretionary authority to vote on such
stockholder proposal, even though the proposal is not discussed in the related
Proxy Statement.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of InfoSpace
Redmond, Washington

  We have audited the accompanying consolidated balance sheets of InfoSpace,
Inc. and subsidiaries (the Company) as of December 31, 1999 and 1998, and the
related consolidated statements of operations, changes in stockholders' equity
and accumulated other comprehensive income, and cash flows for the years ended
December 31, 1999, 1998 and 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits. The consolidated
financial statements give retroactive effect to the merger of the Company and
Prio, Inc. (Prio), which has been accounted for as a pooling of interests as
described in Note 7 to the consolidated financial statements. We did not audit
the financial statements of Prio for the years ended December 31, 1998 and
1997, which statements reflect total revenues of $9,000 and $74,000,
respectively, net loss of $14,150,000 and $8,283,000 for the respective years
then ended, and total assets of $30,665,000 as of December 31, 1998. Those
financial statements were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to the amounts included
for Prio for such periods, is based solely on the report of such other
auditors.

  We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits and the report of the other auditors provide a reasonable basis for our
opinion.

  In our opinion, based on our audits and the report of the other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of InfoSpace, Inc. and subsidiaries
as of December 31, 1999 and 1998, and results of their operations and their
cash flows for the years ended December 31, 1999, 1998 and 1997, in conformity
with accounting principles generally accepted in the United States of America.

The Board of Directors
Prio, Inc.:

  We have audited the balance sheet of Prio, Inc. (the Company), formerly
SaveSmart, Inc., (a development stage enterprise) as of December 31, 1998, and
related statements of operations, shareholders' deficiency, and cash flows for
each of the years in the two-year period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence

also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Prio, Inc. (a development
stage enterprise) as of December 31, 1998, and the results of its operations
and its cash flows for each of the years in the two-year period ended December
31, 1998, in conformity with generally accepted accounting principles.

Note 1: Summary of Significant Accounting Policies

  Description of business: InfoSpace, Inc., (the Company or InfoSpace),
previously known as InfoSpace.com, Inc., a Delaware corporation, was founded in
March 1996. The Company is an international Internet information infrastructure
services company that provides enabling technologies and Internet services to
Web sites, merchants and wireless devices.

  Principles of consolidation: The consolidated financial statements include
the accounts of the Company and its subsidiaries. All significant intercompany
accounts and transactions have been eliminated.

  Business combinations: Business combinations accounted for under the purchase
method of accounting include the results of operations of the acquired business
from the date of acquisition. Net assets of the companies acquired are recorded
at their fair value at the date of acquisition. Amounts allocated to in-process
research and development are expensed in the period of acquisition.

  Business combinations accounted for under the pooling-of-interests method of
accounting include the financial position and results of operations as if the
acquired company had been a wholly-owned subsidiary since inception. In such
cases, the assets, liabilities and stockholders' equity of the acquired
entities were combined with the Company's respective amounts at their recorded
values. The equity of the acquired entity is reflected on an as-if-converted
basis to InfoSpace equity at the time of issuance. Prior period financial
statements have been recast to give effect to the merger. Certain
reclassifications have been made to the financial statements of the pooled
entities to conform with the Company.

  Unaudited information: The accompanying unaudited consolidated financial
statements include all adjustments, consisting of normal recurring adjustments
that, in the opinion of management, are necessary to present fairly the
financial information set forth therein. Prior period financial statements have
been recast to give effect to mergers accounted for as a pooling of interests.
Results of operations for the three and six-month periods ended June 30, 2000
are not necessarily indicative of future financial results.

  Cash and cash equivalents: The Company considers all highly liquid debt
instruments with an original maturity of 90 days or less to be cash
equivalents. Cash and cash equivalents are carried at cost, which approximates
market.

  Investments: The Company principally invests its available cash in high-
quality corporate issuers, and in debt instruments of the U.S. Government and
its agencies. All debt instruments with original maturities greater than three
months up to one year from the balance sheet date are considered short-term
investments. Investments maturing after twelve months from the balance sheet
date are considered long-term. The Company accounts for investments in
accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and
Equity Securities." The Company's short-term and long-term investments are
classified as held-to-maturity as of the balance sheet date as the company has
both the ability and the intent to hold the investments to maturity and are
reported at amortized cost.

  Property and equipment: Property and equipment are stated at cost.
Depreciation is computed under the straight-line method over the following
estimated useful lives:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  On January 1, 1999, the Company adopted Statement of Position 98-1,
Accounting for the Costs of Computer Software developed or Obtained for
Internal Use. This requires capitalization of certain costs incurred in
connection with developing or obtaining internal use software and amortization
of these costs over future periods, which prior to the adoption of SOP 98-1,
were expensed. For the year ended December 31, 1999, the Company has
capitalized $478,304 of costs associated with internally developed software.
These costs are included in property and equipment on the accompanying balance
sheet and are generally amortized over five years.

  Intangible assets: Goodwill, purchased technology and other intangibles are
amortized on a straight-line basis over their estimated useful lives. Goodwill
and purchased technology are generally amortized over three to five years.
Other intangibles, primarily consisting of purchased trademarks and domain name
licenses are amortized over an estimated useful life of three years.

  Other investments: The Company invests in equity investments of public and
privately-held technology companies for business and strategic purposes. These
investments are included in long-term assets and are classified as available-
for-sale. Investments in companies whose securities are not publicly traded are
recorded at cost. Investments in companies whose securities are publicly traded
are recorded at fair value. Unrealized gains or losses on these investments are
recorded as comprehensive income in the Company's stockholders' equity.
Realized gains or losses are recorded based on the identified cost of the
investment sold.

  Other long-lived assets: Management periodically evaluates long-lived assets,
consisting primarily of purchased technology, goodwill, property and equipment,
to determine whether there has been any impairment of the value of these assets
and the appropriateness of their estimated remaining life. No impairment loss
has been recognized through December 31, 1999.

  Revenue recognition: The Company's revenues are derived from its consumer,
merchant and wireless services. These include advertising, content carriage,
licensing fees, e-commerce fees and guaranteed transaction fees in lieu of
revenue share.

  Advertising: Revenues from contracts based on the number of impressions
displayed or click throughs provided are recognized as services are rendered.

  Content carriage: Revenues from fixed fee content carriage agreements are
recognized ratably over the related contract term. For content carriage fee
contracts that are performance based with an established maximum, the Company
recognizes revenues as the services are rendered, not to exceed the maximum
amount over the fixed term.

  Licensing fees: Revenue from licensed services is recognized ratably over the
term of the license agreement.

  Commerce fees: Transaction fees are recognized in the period the transaction
occurred and was reported to the Company by the content providers or online
merchants.

  Guaranteed transaction fees: Guaranteed minimum payments are recognized
ratably over the term of the agreements. Revenues earned above the guaranteed
minimum payments are recognized ratably over the remaining term of the
agreements.

  Also included in revenues are barter revenues generated from exchanging
banners for banners, banners for content or banners for print or other
advertising. Barter revenues are recorded at the lower of the estimated fair
market value of goods and services received or impressions given, and are
recognized when

                                INFOSPACE, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

the Company's advertisements are run. For barter agreements, the Company
records a receivable or liability at the end of the reporting period for the
difference in the fair value of the services provided or received.

  Cost of revenues: Cost of revenues consists of expenses associated with the
enhancement, maintenance and support of our content services, including direct
personnel expenses, communication costs such as high-speed Internet access,
server equipment depreciation and content license fees. Fees paid for content
licenses are capitalized and amortized over the license period.

  Product development: Product development expenses consist principally of
personnel costs for research, design, development, enhancement and maintenance
of the proprietary technology used to integrate and distribute the Company's
consumer, merchant and wireless services. These expenses are net of capitalized
internally developed software costs.

  Advertising costs: Costs for print advertising are recorded as expense when
the advertisement appears. Advertising costs related to electronic impressions
are recorded as expense as impressions are provided. Advertising expense
totaled approximately $5,369,000, $1,280,000 and $263,000 for the years ended
December 31, 1999, 1998 and 1997, respectively.

  Unearned compensation: Unearned compensation represents the unamortized
difference between the option exercise price and the fair market value of the
Company's common stock for shares subject to grant at the grant date, for
options issued under the Company's stock incentive plan (Note 5). The
amortization of unearned compensation is charged to operations and is amortized
over the vesting period of the options.

  Deferred expense-warrants: Deferred expense-warrants represents the fair
value of the warrants that were issued and is expensed ratably over the four
year vesting period. The amortization of deferred warrant expense is charged to
sales and marketing expense.

  Acquisition and other related charges: Acquisition and other related charges
consist of in-process research and development and other one-time charges
related directly to the acquisitions, such as legal and accounting fees.

  Other non-recurring charges: Other non-recurring charges in the first quarter
of 2000 consist of expense recorded for the fair market value of warrants
issued by Prio, Inc. Prio had previously issued warrants for services provided.
These warrants were accounted for under variable plan accounting. Subsequent to
the acquisition of Prio, the agreement with these warrants was terminated and
the remaining unvested warrants accelerated to full vesting. Other non-
recurring charges in 1999 consist of costs associated with litigation
settlements.

  Foreign currencies: Assets and liabilities denominated in foreign currencies
are translated at the exchange rate on the balance sheet date. Translation
adjustments resulting from this process are charged or credited to other
comprehensive income. Revenue and expenses are translated at average rates of
exchange prevailing during the period. Gains and losses on foreign currency
transactions are included in Other income, net.

  Concentration of credit risk: Financial instruments that potentially subject
the Company to concentrations of credit risk consist primarily of cash
equivalents, short-term investments, and trade receivables. These instruments
are generally unsecured and uninsured. The Company places its cash equivalents
and investments with major financial institutions. The Company operates in one
business segment and sells advertising to various companies across several
industries. Accounts receivable are typically

                                      F-11
<PAGE>

                                INFOSPACE, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

unsecured and are derived from revenues earned from customers primarily located
in the United States operating in a wide variety of industries and geographic
areas. The Company performs ongoing credit evaluations of its customers and
maintains reserves for potential credit losses. For the years ended December
31, 1999 and 1998, one customer accounted for approximately 21% and 20% of
revenues, respectively. For the year ended December 31, 1997, no one customer
accounted for more than 10% of revenues. At December 31, 1999, one customer
accounted for approximately 14% of accounts receivable. At December 31, 1998,
one customer accounted for approximately 26% of accounts receivable.

  Income taxes: The Company has adopted Statement of Financial Accounting
Standards (SFAS) No. 109, Accounting for Income Taxes. Under SFAS No. 109,
deferred tax assets, including net operating loss carryforwards, and
liabilities are determined based on temporary differences between the book and
tax basis of assets and liabilities. The Company believes sufficient
uncertainty exists regarding the realizability of the deferred tax assets such
that a full valuation allowance is required.

  Reclassification: Certain reclassifications have been made to the 1998 and
1997 balances to conform with the 1999 presentation.

  Reverse stock split: A one-for-two reverse stock split of the Company's
common stock was effected on August 25, 1998. All references in the financial
statements to shares, share prices, per share amounts and stock plans have been
adjusted retroactively for the one-for-two reverse stock split.

  Stock splits: A two-for-one stock split of the Company's common stock was
effected in May 1999. A second two-for-one stock split of the Company's common
stock was effected in January 2000. A third two-for-one stock split of the
Company's common stock was effected in April 2000. All references in the
financial statements to shares, share prices, per share amounts and stock plans
have been adjusted retroactively for these stock splits.

  Use of estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual amounts may differ from estimates.

  Recent accounting pronouncements: In December 1999, the Securities and
Exchange Commission staff issued Staff Accounting Bulletin (SAB) 101, Revenue
Recognition in Financial Statements. The Company adopted SAB 101 on January 1,
2000. Prior to January 1, 2000 and implementation of the SAB, the Company
recorded revenues from customers for development fees, implementation fees
and/or integration fees when the service was completed. If this revenue was
recognized on a straight-line basis over the term of the related service
agreements, in accordance with SAB 101, the Company would have deferred
$719,216 as of January 2000. In accordance with SAB 101, the Company recorded a
cumulative effect of change in accounting principle of $719,216. The Company
recorded $367,896 in revenue in the six months ended June 30, 2000 (unaudited)
related to this deferred revenue. The remaining balance will be recognized from
July 2000 through November 2001.

  In June 1998, the FASB issued SFAS No. 133, Accounting for Derivatives and
Hedging Activities. SFAS 133, as amended by SFAS 137, establishes accounting
and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. Because the Company has never used
nor currently intends to use derivatives, management does not anticipate that
the adoption of this new standard will have a significant effect on earnings or
the financial position of the Company.

  In January 1996, the Company executed a demand note with a commercial entity
in the amount of $250,000, which is the amount outstanding as of December 31,
1999. The note bears interest at LIBOR (5.82% as of December 31, 1999) plus 1%
per annum, and the full principal amount plus interest is due on demand. The
note may be converted into shares of the Company's preferred stock at the then
prevailing conversion or market price, until the note is paid in full. In
January 2000, the Company exercised its right to repay the demand note in
accordance with the terms of the note payable (the "Terms"), by sending a check
for full amount of principal and accrued interest. Lender attempted to reject
the repayment on the grounds that it had attempted to convert the note in early
1998. Management believes that such lender's claim is without merit based on
the Terms and intends to defend its claim vigorously.

  In June 1997, the Company entered into a loan and security agreement (the
"Agreement," as amended in September 1998) with Phoenix Leasing Incorporated.
The Agreement provides the Company with
available borrowings not to exceed $2,124,000, in aggregate, $2,099,000 of
which was drawn through December 31, 1999. Principal and interest are due in 36
equal monthly installments with a final payment equal to 15% of the original
principal amount due on the 37th month from the time of the borrowing. The
notes bear interest at effective rates ranging from 15.0% to 16.4% per annum.
Principal repayments for the borrowings are due as follows: 2000, $607,000;
2001, $561,000; and 2002, $50,000.

  In October 1997, the Company entered into a joint venture agreement (the
Joint Agreement) with DataCard to form DSIPL. Pursuant to the terms of the
Joint Agreement, DSIPL will perform development services for DataCard and the
Company. In connection with the Joint Agreement, DataCard loaned Prio $500,000,
the proceeds of which were used by Prio to fund DSIPL. DataCard had the option
to convert $250,000 of the notes payable into 50% ownership interest in DSIPL,
which was exercised by DataCard in May 1998. The remaining amount of the note
of $144,000 was paid in full during 1999.

Note 5:  Other Investments

  The Company invests in equity instruments of public and privately-held
technology companies for business and strategic purposes. These investments are
recorded as long-term assets and are classified as available-for-sale
securities.

  The Company also holds warrants in public and privately-held technology
companies for business and strategic purposes. Certain of these warrant
agreements contain provisions that require the Company to meet specific
performance criteria for the warrants to vest. When the Company meets its
performance obligations it records revenue equal to the difference in the
exercise price of the warrant and the fair market value of the underlying
security. The Company recorded revenue in the amount of $1,895,325 for vesting
in performance warrants and stock for the year ended December 31, 1999.

  Restated 1996 Flexible Stock Incentive Plan: On June 3, 1998, the Board of
Directors approved the Restated 1996 Flexible Stock Incentive Plan (the Plan).
The Plan provides employees (including officers and directors who are
employees) of the Company an opportunity to purchase shares of stock pursuant
to options which may qualify as incentive stock options under Section 422 of
the Internal Revenue Code of 1986, as amended (the Code), and employees,
officers, directors, independent contractors and consultants of the Company an
opportunity to purchase shares of stock pursuant to options which are not
described in Section 422 of the Code (nonqualified stock options). The Plan
also provides for the sale or bonus of stock to eligible individuals in
connection with the performance of service for the Company. Finally, the Plan
authorizes the grant of stock appreciation rights, either separately or in
tandem with stock options, which

entitle holders to cash compensation measured by appreciation in the value of
the stock. Not more than 3,000,000 shares of stock shall be available for the
grant of options or the issuance of stock under the Plan. If an option is
surrendered or for any other reason ceases to be exercisable in whole or in
part, the shares which were subject to option but on which the option has not
been exercised shall continue to be available under the Plan. The Plan is
administered by the Board of Directors. Options granted under the Plan
typically vest over four years, 25% one year from the date of grant and ratably
thereafter on a monthly basis. Additional options have been granted to retain
certain existing employees, which options vest monthly over four years.

  On June 3, 1998, the Board of Directors approved the Option Exchange Program
and the Option Replacement Program, allowing employees of the Company to
exchange their nonqualified stock options for incentive stock options.
Nonqualified stock options to purchase a total of 2,900,424 shares were
exchanged for incentive stock options to purchase the equivalent number of
shares with an exercise price equal to the fair market value at the date of
exchange.

  On May 24, 1999, the stockholders approved an amendment to the Plan to
increase the number of shares of Common Stock reserved for issuance thereunder
by 8,000,000 shares. On January 21, 2000, the Board of Directors approved the
deletion of this limitation.

  On May 24, 1999, the stockholders approved an amendment to the Plan to
annually increase the number of shares reserved for issuance on the first day
of the Company's fiscal year beginning January 1, 2000 by an amount equal to
the lesser of (A) 8,000,000 shares, (B) three percent of the Company's
outstanding shares at the end of the Company's preceding fiscal year, and (C) a
lesser amount determined by the Board of Directors.

  On May 24, 1999, the stockholders approved an amendment to the Plan to limit
the number of shares of Common Stock that may be granted to any one individual
pursuant to stock options in any fiscal year of the Company to 8,000,000
shares, plus an additional 8,000,000 shares in connection with his or her
initial employment with the Company, which grant shall not count against the
limit.

  Included in the table below as outstanding at December 31, 1999 are options
to purchase 1,630,675 shares that were issued outside of the Plan, of which

  The Company granted 3,067,527 options in the first quarter of 2000 at
exercise prices equal to market prices. The weighted average exercise price and
fair market value of these options is $85.45 and $88.28, respectively.

  The Company has elected to follow the measurement provisions of Accounting
Principles Board Opinion No. 25, under which no recognition of expense is
required in accounting for stock options granted to employees for which the
exercise price equals or exceeds the fair market value of the stock at the
grant date. In those cases where options have been granted when the option
price is below fair market value, the Company recognizes compensation expense
over the vesting period using the aggregated percentage of compensation accrued
method as prescribed by Financial Standards Accounting Board Interpretation
No. 28. Compensation expense of $884,714, $1,246,132, and $143,922, was
recognized during the years

ended December 31, 1999, 1998 and 1997, respectively, and $510,037 for the six
months ended June 30, 2000 for options granted with exercise prices less than
grant date fair market value.

  To estimate compensation expense which would be recognized under SFAS No.
123, Accounting for Stock-based Compensation, the Company uses the modified
Black-Scholes option-pricing model with the following weighted-average
assumptions for options granted through December 31, 1999: risk-free interest
rate ranging from 4.24% to 6.56%; expected dividend yield of 0-%; 121%
volatility; and an expected life of five years for 1999 and six years for 1998
and prior.

  Had compensation expense for the Plan been determined based on fair value at
the grant dates for awards under the Plan consistent with SFAS No. 123,
Accounting for Stock-Based Compensation, the Company's net losses for the years
ended December 31, 1999, 1998 and 1997, and six months ended June 30, 2000

  In July 1998, the Company issued warrants to purchase 3,823,736 shares of
common stock at an exercise price of $.003 to a former consultant in
conjunction with the acquisition of Outpost (Note 4). All of these warrants
were exercised in 1999.

  On August 24, 1998, the Company issued to AOL warrants to purchase up to
7,919,328 shares of common stock, which warrants vest in 16 equal quarterly
installments over four years, conditioned on the delivery by AOL of a minimum
number of searches each quarter on the Company's white pages directory service.
The warrants have an exercise price of $1.50 per share. The warrants were
valued using the fair value method, as required under SFAS No. 123. The fair
value of the warrants was approximately $3,300,000 at the date of grant, and is
being amortized ratably over the four-year vesting period. The underlying
assumptions used to determine the value of the warrants are an expected life of
six years and a 5.5% risk-free interest rate.

  The Company assumed warrants to purchase 288,808 shares of the Company's
common stock as a result of the acquisition of INEX Corporation (Note 7). These
warrants were issued to seven third-party participants. Two of the third party
participants exercised 24,486 of the warrants in December 1999. The remaining
warrants expire between January 29, 2000 and July 31, 2000. The range of
exercise prices and number outstanding at December 31, 1999 are as follows:

  The Company assumed warrants to purchase 474,203 shares of the Company's
stock as a result of the acquisition of Prio, Inc. with an exercise price of
$9.97 per share. The warrants were issued to a third-party participant in
December of 1998 and are exercisable over a maximum of a 48 month period, based
on achievement of performance milestones and other criteria as defined in the
warrant agreement. In 1999, Prio recorded warrant expense for all the warrants
issued, of which 118,551 were unvested at December 31, 1999, of $18 million
based on the fair value of these warrants using the Black-Scholes option
pricing model with the following assumptions: dividend yield of 0%; expected
volatility of 75%; contractual life of nine years; and risk-free interest rate
of 6.37%. The compensation cost for the unvested warrants was remeasured when
vesting occurred and additional warrant expense of $2.9 million was recognized
in the six months ended June 30, 2000.

  Stock purchase rights plan: On June 26, 1998, the Board of Directors approved
the InfoSpace Stock Purchase Rights Plan. The plan was offered to employees of
the Company and its subsidiaries. The purpose of the plan was to provide an
opportunity for employees to invest in the Company and increase their incentive
to remain with the Company. A maximum of 4,000,000 shares of common stock were
available for issuance under the plan. During July 1998, the Company offered
shares to employees under the plan, resulting in the sale of 1,786,008 shares
at $.94 per share. The plan was terminated on August 24, 1998.

  1998 Employee Stock Purchase Plan: The Company adopted the 1998 Employee
Stock Purchase Plan (the ESPP) in August 1998. The ESPP was implemented upon
the effectiveness of the initial public offering. The ESPP is intended to
qualify under Section 423 of the Code, and permits eligible employees of the
Company and its subsidiaries to purchase common stock through payroll
deductions of up to 15% of their compensation. Under the ESPP, no employee may
purchase common stock worth more than $25,000 in any calendar year, valued as
of the first day of each offering period. In addition, owners of 5% or more of
the Company or subsidiary's common stock and the Company's executives may not
participate in the ESPP. An aggregate of 3,600,000 shares of common stock are
authorized for issuance under the ESPP.

  The ESPP was implemented with six-month offering periods, with the first such
period commencing upon the effectiveness of the initial public offering and
ending July 31, 1999. Thereafter, offering periods will begin on each February
1 and August 1. The price of common stock purchased under the ESPP will be the
lesser of 85% of the fair market value on the first day of an offering period
and 85% of the fair market value on the last day of an offering period, except
that the purchase price for the first offering period was equal to the lesser
of 100% of the initial public offering price of the common stock offered hereby
and 85% of the fair market value on July 31, 1999. The ESPP does not have a
fixed expiration date, but may be terminated by the Company's Board of
Directors at any time. There were 152,580 shares issued for the first ESPP
offering period which ended on July 31, 1999.

Note 7: Business Combinations

  Millet Software (unaudited): On March 31, 2000 the Company acquired all of
the common stock of Millet Software (privacybank.com) for purchase
consideration of 488,224 shares of the Company's common stock and acquisition
expenses of $54,531. Millet was a privately held company that developed secure
technology that provides an automated process for filling in payment forms. The
acquisition was accounted for as a purchase in accordance with Accounting
Principles Board Opinion ("APB") No. 16. Results of operations for Millet have
been included with those of the Company for the period subsequent to the date
of acquisition.

  The purchase price was allocated to the assets acquired and liabilities
assumed based on their estimated fair values as follows:

  The $6,000,000 value of purchased technology includes purchased in-process
research and development for future InfoSpace products. Generally accepted
accounting principles in the U.S. require purchased in-process research and
development with no alternative future use to be recorded and charged to
expense in the period acquired. Accordingly, the results of operations for the
quarter ended March 31, 2000, include the write-off of $2,400,000 of purchased

  Litigation: On December 15, 1999, a complaint was filed against the Company
on behalf of a former employee in federal court in New Jersey alleging claims
for breach of contract, breach of the covenant of good faith and fair dealing,
fraud, negligent misrepresentation, and promissory estoppel. The former
employee contends he agreed to work for InfoSpace on the basis of certain
misrepresentations, that he entered into an agreement with the Company that
entitles him to an option to purchase 300,000 shares of the Company's common
stock, and that he was terminated without cause. The former employee seeks
(1) the right to purchase the shares of stock, (2) unspecified compensatory and
punitive damages, and (3) litigation costs and attorney's fees. On January 31,
2000, the Company answered the complaint. Discovery is complete. The case has
been transferred to the United States District Court for the Western District
of Washington and a trial date has not yet been set. The Company is currently
investigating the claims at issue and believes the Company has meritorious
defenses to such claims. Nevertheless, litigation is uncertain and the Company
may not prevail in this suit.

  One of the shareholders of INEX Corporation filed a complaint on September
22, 1999 alleging that the original shareholders of INEX and INEX itself were
bound by a shareholders agreement that entitled it to pre-emptive rights and
rights of first refusal. The complaint alleges that INEX improperly made
private placements, issued employee options and permitted share transfers after
February 1997. The complainant alleges it should have acquired rights in
approximately 88% of the INEX share capital, which would be less than one
percent of our common stock. The complaint also alleges other breaches of
contract, breach of fiduciary duty, corporate oppression, unlawful interference
with economic relations and conspiracy. The complaint was amended on December
20, 1999 to allege that the Company assumed the obligations of

INEX under the alleged shareholders agreement as a result of our acquisition of
INEX on October 14, 1999. The complaint seeks damages against the Company and
named former INEX shareholders for the difference between the issue or sale
price of INEX shares issued or transferred after February 1997 and before
October 14, 1999 and the highest trading value of shares of the Company's
common stock received or receivable in exchange attained before the date of
trial. In the alternative, the complaint seeks special damages in the amount of
$50,000,000 Canadian. The complaint also seeks $500,000 in punitive damages and
constructive trusts, equitable liens and tracing remedies in both INEX shares
formerly held by certain shareholders and shares of the Company's common stock
received by those shareholders in exchange for their INEX shares. 435,134
shares of the Company's common stock and shares exchangeable into the Company's
common stock that were part of the INEX purchase price which are held to
satisfy this claim. The Company is currently investigating the claims at issue
and believes the Company has meritorious defenses to such claims. Nevertheless,
litigation is uncertain and the Company may not prevail in this suit.

  On December 23, 1998, the Company initiated litigation against Internet
Yellow Pages, Inc., or IYP, by filing suit in United States District Court for
the Western District of Washington. On February 3, 1999, the Company served a
first amended complaint on IYP and Greg Crane, an agent of IYP, in which the
Company asserted claims for (a) account stated, (b) breach of contract, and (c)
fraud. On March 5, 1999, IYP answered the Company's complaint in the Washington
action, and asserted claims for breach of contract, fraud, extortion and
Consumer Protection Act violations. IYP seeks relief consisting of
approximately $1,500,000 and other unquantified money damages and treble
damages for the CPA and attorneys' fees. Discovery is complete. The Company is
currently investigating the claims at issue and believes the Company has
meritorious defenses to such claims. Nevertheless, litigation is uncertain and
the Company may not prevail in these suits. The case is scheduled for a
streamlined mini-trial before a federal magistrate on July 31, 2000.

  Settlement of litigation: On February 8, 2000, the Company reached a
settlement with an alleged former employee. Under the terms of the settlement,
the alleged former employee received a cash payment of $10.5 million. As this
subsequent event was settled prior to the issuance of the financial statements,
the expense has been recorded in the fourth quarter of 1999 in Other non-
recurring expense.


  On February 22, 1999, the Company reached a settlement with a former
employee. Under the terms of the settlement the former employee received a cash
payment of $4.5 million. As this subsequent event was settled after December
31, 1998 but prior to the issuance of the financial statements, the expense was
recorded in the fourth quarter of 1998 in Other non-recurring expense.

  Contingencies: In the Company's early stage of development, the Company did
not clearly document arrangements with employees and consultants, including
matters relating to the issuance of stock options. As a result of this
incomplete documentation, the Company may receive claims in the future
asserting rights to acquire common stock.

  At December 31, 1999, 1998 and 1997, the Company fully reserved its deferred
tax assets. The Company believes sufficient uncertainty exists regarding the
realizability of the deferred tax assets such that a full valuation allowance
is required. The net change in the valuation allowance during the years ended
December 31, 1999, 1998 and 1997, was $33,423,000, $9,575,000 and $3,080,000,
respectively.

  As of December 31, 1999, the Company's federal net operating loss
carryforward for income tax purposes was approximately $70 million. If not
utilized, the federal net operating loss carryforwards will begin to expire
between 2011 and 2019. Changes in ownership, as defined by Section 382 of the
Code, may limit the amount of net operating loss carryforwards used in any one
year. The Company's federal research tax credit carryforwards for income tax
purposes are approximately $1,492,000. If not utilized, the federal tax credit
carryforwards will begin to expire between 2011 and 2019.

  Deferred tax assets of approximately $17.5 million as of December 31, 1999
pertain to certain net operating loss carryforwards and credit carryforwards
resulting from the exercise of employee stock options. When recognized, the tax
benefit of these loss and credit carryforwards are accounted for as a credit to
additional paid-in capital rather than a reduction of the income tax provision.

  The Company acquired Prio, Inc. in February 2000. As of the date of
acquisition, the availability of Prio's tax attributes consisting primarily of
net operating loss carryforwards and credit carryforwards will be limited under
Federal and California tax laws. As of December 31, 1998, Prio, Inc. has
federal net operating loss carryforwards of $20,750,000, which will expire
between 2009 and 2019 and California net operating loss carryforwards of
$21,033,000 which will expire from 2001 through 2004. Prio also has available
research tax credit carryforwards of $1,120,000, which will expire between 2011
and 2019 and California research and manufacturing credits of $693,000 which
will carry forward indefinitely.

Note 10: Net Loss Per Share

  The Company has adopted SFAS No. 128, Earnings per Share. Basic earnings per
share is computed using the weighted average number of common shares
outstanding during the period. Diluted earnings per share is computed using the
weighted average number of common and common equivalent shares outstanding
during the period. Common equivalent shares consist of the incremental common
shares issuable upon conversion of the exercise of stock options and warrants
(using the treasury stock method). Common equivalent shares are excluded from
the computation if their effect is antidilutive. The Company had a net loss for
all periods presented herein; therefore, none of the options and warrants
outstanding during each of the periods presented, as discussed in Note 5, were
included in the computation of diluted loss per share as they were
antidilutive. Options and warrants to purchase a total of 31,909,169,
12,757,182 and 5,517,716 shares of common stock were excluded from the
calculations of diluted loss per share for the years ended December 31, 1999,
1998 and 1997, respectively. 680,000 contingently issuable shares of common
stock have been excluded from the calculation of basic earnings per share for
the year ended December 31, 1997 (Note 6).

Note 11: Information on Products and Services

  In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, SFAS No. 131 establishes standards for the
way that companies report information about operating segments in annual
financial statements. It also establishes standards for related disclosures
about products and services, geographic areas, and major customers as well as
the reporting of selected information about operating segments in interim
financial statements for the year ended December 31, 1998. The adoption of SFAS
131 did not have a material effect on the Company's primary consolidated
financial statements but did affect the Company's disclosures.

  The Company generates substantially all of its revenues through integrated
technology and services delivered through a common physical infrastructure, and
therefore the Company has only one reportable segment. Substantially all
revenues are generated from domestic sources. Substantially all of the
Company's long-lived assets are physically located within the United States.

  Total operating expenses are controlled centrally based on established
budgets by operating department. Operating departments include product
development, sales and marketing, account management and customer service, and
finance and administration. Assets, technology, and personnel resources of the
Company are shared and utilized for all of the Company's service offerings.
These resources are allocated based on contractual requirements, the
identification of enhancements to the current service offerings, and other non-
financial criteria. The Company does not prepare operating statements by
revenue source. The Company does not account for, and does not report to
management, its assets or capital expenditures by revenue source.

affiliate for consulting services provided by the affiliate to Prio. The total
expense for such consulting services amounted to $100,000 and $270,000 for the
years ended December 31, 1999 and 1998, respectively.

  The outstanding current portion of the advance is $187,000 and $100,000 as of
December 31, 1999 and 1998, respectively. The long-term portion of $50,000 as
of December 31, 1999 is included in Other Assets.

Note 13: Investments in Joint Ventures

  In 1998, the Company entered into a joint venture with Thomson Directories
Limited to form TDL InfoSpace to replicate the Company's infrastructure
services in Europe. TDL InfoSpace has targeted the United Kingdom as its first

the license agreement between Thomson and TDL InfoSpace, Thomson licenses its
U.K. directory information database to TDL InfoSpace. Under the Web site
services agreement between Thomson and TDL InfoSpace, Thomson also sells
Internet yellow pages advertising for the joint venture through its local sales
force. Under the Company's license agreement with TDL InfoSpace, the Company

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and shareholders of
Saraide, Inc. and Subsidiaries
San Mateo, California

  We have audited the accompanying consolidated balance sheets of Saraide, Inc.
and subsidiaries (collectively, the "Company") as of December 31, 1999 and
1998, and the related consolidated statements of operations, stockholders'
equity and cash flows for the year ended December 31, 1999, and the period from
inception (June 30, 1998) to December 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

  We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

  In our opinion, such consolidated financial statements present fairly, in all
material respects, the consolidated financial position of the Company as of
December 31, 1999 and 1998, and the results of its operations and its cash
flows for the year ended December 31, 1999, and the period from inception
(June 30, 1998) to December 31, 1998, in conformity with accounting principles
generally accepted in the United States of America.

  The Company was in the development stage at December 31, 1998; during the
year ended December 31, 1999, the Company completed its development activities
and commenced its planned principal operations.

                         SARAIDE, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  Year Ended December 31, 1999 and Period from
              Inception (June 30, 1998) Through December 31, 1998

Note 1: Nature of Business and Subsequent Event

  Business--Saraide, Inc. (a Delaware corporation) and its subsidiaries
(collectively, the "Company") develops processing and transmission engines and
establishes relationships with data or information providers for the purposes
of developing, improving and distributing services that enable wireless
carriers and internet content providers to create and deliver wireless internet
services via both Short Message Service ("SMS") and Wireless Application
Protocol ("WAP") technologies.

  During the period from its inception (June 30, 1998) to December 31, 1998,
the Company devoted substantially all of its efforts to recruiting personnel to
conduct research, product development, and sales and marketing and did not
generate revenues from services. During the year ended December 31, 1999, the
Company completed its development activities and commenced its planned
principal operations.

  Subsequent Events--On March 10, 2000, the Company was acquired by InfoSpace,
Inc. (formerly InfoSpace.com, Inc.), a global Internet information
infrastructure services company. Under the terms of the Reorganization
Agreement, InfoSpace's wireless services were merged with and into the Company,
and InfoSpace issued 9,590,864 shares (or options to purchase shares), as
adjusted for a subsequent 2:1 stock split, of its common stock in exchange for
eighty-percent (80%) of the then outstanding shares of the Company's common and
preferred stock, and options to purchase shares of common stock.

Note 2: Summary of Significant Accounting Policies

  Basis of Presentation--The consolidated financial statements include the
accounts of Saraide, Inc. and its wholly-owned subsidiaries Saraide.com Ltd.
(Canada), GSM Information Network, b.v. (GIN) and Saraide Sarl (France). All
intercompany balances and transactions have been eliminated.

  Business combinations--The acquisition of GIN (Note 3) was accounted for
under the purchase method of accounting in accordance with the provisions of
Accounting Principles Board Opinion ("APB") No. 16, "Business Combinations",
and the consolidated financial statements include the results of operations of
GIN from the date of acquisition. Net assets of GIN were recorded at their fair
value at the date of acquisition with the excess of the purchase price over
such fair values allocated to goodwill.

  Use of Estimates in Preparation of Financial Statements--The preparation of
financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosures of contingent
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

  Cash and Cash Equivalents--The Company considers all highly liquid
investments with an original maturity of three months or less to be cash
equivalents. Cash and cash equivalents include amounts held in bank demand
accounts and highly liquid money market funds. The carrying amount of money
market funds approximates fair value due to the short maturity of these
instruments. The Company's policy is to place its cash and cash equivalents
with high credit quality financial institutions, government agencies and
corporate entities.

  Property and Equipment--Property and equipment are recorded at cost and
depreciated using the straight-line method over their estimated useful lives.
Computer equipment, computer software, computer licenses and other property,
plant and equipment are depreciated over periods ranging from 3 to 5 years.

                                      F-38

                         SARAIDE, INC. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Leasehold improvements are amortized over the shorter of their estimated lives,
being 3 years, or the lease term, including option periods, as appropriate.

  Intangible Assets--Intangible assets, consisting of the rights and title to
Northern Telecom Ltd.'s DNSP developed software, goodwill and other intangible
assets associated with the acquisition of GIN (Note 3), are amortized using the
straight-line basis over their estimated useful lives of five years.
Accumulated amortization was $2,153,000 and $200,000 at December 31, 1999 and
1998, respectively.

  Long-Lived Assets--In accordance with 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", the Company reviews for the
impairment of long-lived assets and certain identifiable intangibles whenever
events or changes in circumstances indicate that the carrying amount of an
asset may not be recoverable. Under SFAS 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 is less than its carrying amount. No
such impairment losses were identified by the Company for the years ended
December 31, 1999 and in the period from inception to December 31, 1998.

  Revenue Recognition--Revenue recognition policies for each revenue source are
as follows:

  .  Services--Service revenues are comprised of amounts earned for the
     delivery of messaging services to wireless carriers. Revenue for these
     services is recognized as incurred and billed. Fees billed to mobile
     phone carriers for the set-up and integration of service agreements are
     deferred and recognized ratably over the contract period.

  .  Consulting--Consulting revenues are recognized upon delivery of services
     to end users.

  Research and Development--Research and development expenses are charged to
operations as incurred.

  Foreign Currency--The functional currencies of the foreign subsidiaries are
the local currencies. Assets and liabilities denominated in foreign currencies
are translated at the exchange rate at the balance sheet date. Translation
adjustments resulting from this process are charged or credited to Other
Comprehensive Income (Loss). Revenue and expenses are translated at average
rates of exchange prevailing during the period. Gains and losses on foreign
currency transactions are included in Other Expense (Income).

  Comprehensive Income (Loss)--At December 31, 1999 and 1998, accumulated other
comprehensive loss consisted of unrealized exchange rate losses.

  Concentration of credit risk--Financial instruments that potentially subject
the Company to concentrations of credit risk consist primarily of cash
equivalents and trade receivables. These instruments are generally unsecured
and uninsured. Accounts receivables are typically unsecured and are derived
from revenues earned from wireless carriers located primarily in the
Netherlands. The Company performs ongoing credit evaluations of its customers
and maintains reserves for potential credit losses. For the years ended
December 31, 1999, four customers accounted for approximately 33%, 17%, 13% and
10% of revenues. At December 31, 1999, three customers accounted for
approximately 20%, 18% and 16% of account receivables.

  Stock-Based Compensation--As permitted by SFAS No. 123, "Accounting for
Stock-Based Compensation", the Company has elected to account for stock-based
awards to employees using the intrinsic value method in accordance with
Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock
Issued to Employees." Options granted to non-employees are accounted for using
the minimum value method prescribed by SFAS 123.

                         SARAIDE, INC. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  Unearned compensation--Unearned compensation represents the unamortized
difference between the option exercise price and the fair value of the
Company's common stock for shares subject to grant at the grant date, for
options issued under the Company's stock incentive plan (Note 7). Amortization
of unearned compensation is charged to operations over the vesting period of
the options.

  Income Taxes--The Company accounts for income taxes using the asset and
liability approach for financial reporting purposes. Under SFAS No. 109
"Accounting for Income Taxes", deferred tax assets, including net operating
loss carryforwards, and liabilities are determined based on temporary
differences between the book and tax basis of assets and liabilities. The
Company has fully provided for its net operating loss carry forwards as
realization is not assured.

  Recent Accounting Pronouncements--In June 1998, the FASB issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133
requires that all derivative instruments be recorded on the balance sheet at
their fair value. Changes in the fair value of derivatives are recorded each
period in current earnings or other comprehensive income, depending on whether
a derivative is designated as part of a hedge transaction and, if it is, the
type of hedge transaction. The Company is required to adopt SFAS No. 133 for
its fiscal year ending December 31, 2001. Management anticipates the adoption
of SFAS No. 133 will not have a significant effect, if any, on the Company's
financial position or results of operations.

  Effective January 1, 1999, the Company adopted Statement of Position No. 98-1
("SOP 98-1"), "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use." Accordingly, in 1999 the Company capitalized direct
payroll costs totaling $1,345,661. No depreciation of such costs was recorded
in fiscal 1999 as the projects were in progress at year-end. Prior to adoption
of SOP 98-1, such software development costs were expensed as incurred.

Note 3: Purchase Business Combinations

  On May 25, 1999, the Company acquired all of the common stock of GIN, a
privately held company, for a purchase consideration of $16,775,000, consisting
of $7,500,000 in cash ($2,500,000 paid in September 1999 and $5,000,000 to be
paid in May 2000); and $9,275,000 representing 1,666,667 shares of Series B
Preferred Stock at $4.50 per share, and warrants to purchase a total of 500,000
shares of Series B Preferred Stock, at $1.00 per share.

  The purchase price was allocated to the assets acquired and liabilities
assumed based on their estimated fair values as follows:

</TABLE>

  Accounting principles generally accepted in the United States of America
require purchased in-process research and development with no alternative
future use to be recorded and charged to expense in the period acquired.
Accordingly, the results of operations for the year ended December 31, 1999,
include the write-off of $3,460,000 of purchased in-process research and
development.

shareholders warrants ("Warrants") expiring December 31, 2004 or on the
occurrence of a liquidity event, as defined, and exercisable for shares of
Series A at a rate of 50,000 shares per $1 million of principal amount of the
applicable Promissory Note, at a purchase price of either (i) $10.00 per share
if the Next Financing were not to have occurred on or prior to December 31,
1999 or (ii) the price per share of the Company's most senior equity securities
issued and sold at the Next Financing if this event were to have occurred on or
prior to December 31, 1999. No beneficial conversion feature was attributed to
the warrants as the $10 per share represent management's best estimate of the
fair value of the Next Financing. The estimated value of the warrants was
$2,795,000 when issued. Such amount was recognized as an addition to
shareholders equity with an offsetting discount against the $10,000,000 face
amount of the first bridge loan. The discount is being amortized to interest
expense over the term of the loan agreements. Such amortization totaled
approximately $745,000 for the year ended December 31, 1999.

  On December 13, 1999, the Company entered into an Election and Termination
Agreement in which the shareholders elected not to convert the Promissory Notes
into equity and to terminate the Warrants in exchange for the Company's promise
to repay the bridge loans as soon as practicable following the closing of the
transactions contemplated by the Reorganization Agreement (Note 1). As a
result, the bridge loans were repaid immediately following the acquisition of
the Company by InfoSpace, Inc., on March 10, 2000.

Note 7: Shareholders' Equity

  Significant terms of the Series A and B preferred shares, which are not
redeemable, are as follows:

  Conversion Rights--Each share of Series A and B is convertible (1) at the
option of the holder into a number of common shares determined by dividing the
Conversion Price, as defined, by the $1.00 and $4.50 Issue Prices,
respectively, and (2) will automatically convert into shares of common stock
upon the closing of a firmly underwritten public offering by the Company
resulting in gross proceeds to the Company of not less than $25,000,000 at a
price per share equal to at least $10.00, as adjusted for dilution, provided
that the valuation of the Company prior to such offering is not less than
$75,000,000 ("Qualified Public Offering"). The Conversion Price is subject to
adjustments for certain dilutive issuances, splits and combinations, as
defined.

  Liquidation Preferences--Upon any dissolution, liquidation or winding up of
the Company, whether voluntary or involuntary, Series A and B holders are
entitled to receive a distribution in the amount per share equal to the Issue
Price as adjusted for stock splits, combinations, recapitalizations or
Preferred Dividends, prior and in preference to any payments to common
stockholders. After payment of these preferences, any remaining assets shall be
distributed ratably to common stock holders.

  Dividend Rights--No dividends or other distributions on common stock unless
the Series A and B holders simultaneously receive a distribution at least equal
to the per share amount to be declared, paid or set aside for the common stock,
multiplied by the number of shares of common stock into which such Series A and
B shares is then convertible.

  Voting Rights--The Series A and B holders have the number of votes equal to
the number of shares of common stock into which such Series A and B shares are
then convertible, and vote together with the common stock holders as a single
class.

Stock Option Plans

  In December 1998, the Board of Directors approved the 1998 Equity Incentive
Plan (the Plan). The Plan provides employees (including officers and directors
who are employees) of the Company an

opportunity to purchase shares of stock pursuant to options which may qualify
as incentive stock options under Section 422 of the Internal Revenue Code of
1986, as amended (the Code), and employees, officers, directors, independent
contractors and consultants of the Company an opportunity to purchase shares of
stock pursuant to options which are not described in Section 422 of the Code
(nonqualified stock options). Not more than 4,185,000 shares of stock shall be
available for the grant of options under the Plan. If an option is surrendered
or for any other reason ceases to be exercisable in whole or in part, the
shares which were subject to option but on which the options have not been
exercised shall continue to be available under the Plan. The Plan is
administered by a committee appointed by the Board of Directors. This committee
has the authority to determine the employees, officers, independent contractors
and consultants (excluding member(s) of the committee) to whom awards will be
made, the amount of the awards, and the other terms and conditions of the
awards. Options granted under the Plan typically vest over four years, ratably
on a quarterly basis.

  If the continuous service of a participant in the Plan terminates due to an
involuntary termination without cause or due to a constructive termination, as
defined, within one month before, or eighteen months after a Change of Control,
as defined, the vesting and exercisability of all stock option awards of the
participant are accelerated in full. The transaction with InfoSpace described
in Note 1 resulted in a Change in Control.

  The following transactions have occurred in the Plan from its adoption
through December 31, 1999:

Additional Stock Plan Information

  As discussed in Note 1, the Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with APB No. 25,
"Accounting for Stock Issued to Employees," and its related

                                      F-43

interpretations. Accordingly, no compensation expense has been recognized in
the financial statements for employee stock awards granted at fair market
value.

  SFAS No. 123, "Accounting for Stock-Based Compensation," requires the
disclosure of pro forma net income as if the Company had adopted the fair value
method. Under SFAS No. 123, the fair value of stock-based awards to employees
is calculated through the use of the minimum value method, which requires
subjective assumptions, including the expected time to exercise, which affect
the calculated values. The Company's calculations were made using the minimum
value method with the following weighted average assumptions for 1999 and 1998,
respectively: no dividends during the expected term; risk-free interest rates
ranging from 4.80% to 5.82%, and expected life of five years. The Company's
calculations are based on a multiple option valuation approach and forfeitures
are recognized as they occur. If the computed fair value of the employee awards
had been amortized to expense over the vesting period of the employee awards,
pro forma net loss would have been $28,566,000 for the fiscal year ended
December 31, 1999 and would not have been materially different from the net
loss for the period from inception through December 31, 1998.

  At December 31, 1999, the Company has available federal and California state
net operating loss carryforwards of approximately $16,934,000 and $2,625,000,
respectively, to offset future taxable income through 2019 and 2003,
respectively. The Company also has net operating loss carryforwards for
Canadian tax purposes of approximately $6,834,000 which will begin to expire in
2005. In addition, the Company has Canadian investment tax credits of
approximately $170,000 available to be carried forward. The investment tax
credits will expire beginning in 2008. At December 31, 1999, the deferred tax
assets have been fully reserved due to the uncertainty surrounding the
realization of such benefits.

  Current tax laws impose substantial restrictions on the utilization of net
operating loss and credit carryforwards in the event of an "ownership change,"
as defined by the Internal Revenue Code. The events described under Note 1 may
limit the Company's ability to utilize its carryforwards.

Note 9: Commitments and Contingencies

  Leases and Third Party Service Agreements--The Company's offices are leased
under various noncancelable operating lease arrangements. The agreements expire
at various dates through May 2004, and certain of the leases contain renewal
options. The Company also leases certain equipment under various

  During 1999, the Company adopted a 401(k) Profit Sharing Plan. Qualified
employees as defined under the Plan are eligible to participate and may make
voluntary contributions subject to the limitation set forth by the Plan or
applicable tax laws. Employee salary contributions are fully vested. The
Company may make discretionary contributions as determined by the Company's
management. There were no contributions made during 1999.

representations set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
the parties agree as follows:

                                   ARTICLE I

                                   THE MERGER

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

  1.2 Effective Time; Closing. Subject to the provisions of this Agreement, the
parties hereto shall cause the Merger to be consummated by filing a Certificate
of Merger with the Secretary of State of the State of Delaware in accordance
with the relevant provisions of Delaware Law (the "Certificate of Merger") (the
time of such filing (or such later time as may be agreed in writing by Company
and Parent and specified in the Certificate of Merger) being the "Effective
Time") as soon as practicable on or after the Closing Date (as herein defined).
The closing of the Merger (the "Closing") shall take place at the offices of
Wilson Sonsini Goodrich & Rosati, Professional Corporation, at a time and date
to be specified by the parties, which shall be no later than the second
business day after the satisfaction or waiver of the conditions set forth in
Article VI, or at such other time, date and location as the parties hereto
agree in writing (the "Closing Date").

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

  1.4 Certificate of Incorporation; Bylaws.

    (a) At the Effective Time, subject to the provisions of Section 5.10, the
  Certificate of Incorporation of Merger Sub shall be the Certificate of
  Incorporation of the Surviving Corporation; provided, however, that the
  Certificate of Incorporation of the Surviving Corporation shall be amended
  so that the name of the Surviving Corporation shall be "Go2Net, Inc.".

    (b) Subject to the provisions of Section 5.10, the Bylaws of Merger Sub,
  as in effect immediately prior to the Effective Time, shall be, at the
  effective time, the Bylaws of the Surviving Corporation.

  1.5 Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Merger Sub immediately prior to the
Effective Time until their successors shall have been duly elected and
qualified. The initial officers of the Surviving Corporation shall be the
officers of Merger Sub immediately prior to the Effective Time.

  1.6 Effect on Capital Stock. Subject to the terms and conditions of this
Agreement, at the Effective Time, by virtue of the Merger and without any
action on the part of Parent, Merger Sub, Company or the holders of any of the
following securities, the following shall occur:

    (a) Conversion of Company Common Stock. In accordance with the
  Certificate of Designation of the Company, each share of Preferred Stock,
  par value $0.01 per share (the "Company Preferred Stock") issued and
  outstanding immediately prior to the Effective Time will automatically be
  converted into 30.2526 shares of Common Stock, par value $0.01 per share,
  of Company (the "Company

                                      A-6
<PAGE>

  Common Stock"). Each share of Company Common Stock issued and outstanding
  immediately prior to the Effective Time (including shares of Preferred
  Stock converted into Company Common Stock, but excluding any share of
  Company Common Stock to be canceled and extinguished pursuant to Section
  1.6(b)) will be automatically converted (subject to Sections 1.6(e) and
  (f)) into 1.82 (the "Exchange Ratio") of a share of Common Stock, par value
  $0.001 per share, of Parent (the "Parent Common Stock"), which shall be
  referred to in this Agreement as the "Merger Consideration." If any shares
  of Company Common Stock outstanding immediately prior to the Effective Time
  are unvested or are subject to a repurchase option, risk of forfeiture or
  other condition under any applicable restricted stock purchase agreement or
  other agreement with Company, then the shares of Parent Common Stock issued
  in exchange for such shares of Company Common Stock will also be unvested
  and subject to the same repurchase option, risk of forfeiture or other
  condition, and the certificates representing such shares of Parent Common
  Stock may accordingly be marked with appropriate legends.

    (b) Cancellation of Company-Owned Stock. Each share of Company Common
  Stock held by Company or any direct or indirect wholly-owned subsidiary of
  Company immediately prior to the Effective Time shall be canceled and
  extinguished without any conversion thereof.

    (c) Stock Options; Employee Stock Purchase Plans. At the Effective Time,
  all options to purchase Company Common Stock then outstanding under
  Company's 2000 Stock Option Plan and 1996 Stock Option Plan, the
  Authorize.Net Corporation 1999 Stock Incentive Plan, the Silicon Investor,
  Inc. 1996 Plan, the Web 21 Stock Option Plan, the Haggle Online, Inc. Non-
  qualified Stock Option Agreement and the IQC Option to Purchase Common
  Stock (collectively, the "Company Option Plans"), and Company Option Plans
  themselves, shall be assumed by Parent in accordance with Section 5.8. At
  the Effective Time, Company's 1999 Employee Stock Purchase Plan (the
  "ESPP") will be terminated in accordance with Section 5.8.

    (d) Capital Stock of Merger Sub. Each share of Common Stock, $0.001 par
  value per share, of Merger Sub (the "Merger Sub Common Stock") issued and
  outstanding immediately prior to the Effective Time shall be converted into
  one validly issued, fully paid and nonassessable share of Common Stock,
  $0.001 par value per share, of the Surviving Corporation. Each certificate
  evidencing ownership of shares of Merger Sub Common Stock shall evidence
  ownership of such shares of capital stock of the Surviving Corporation.

    (e) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted
  to reflect appropriately the effect of any stock split, reverse stock
  split, stock dividend (including any dividend or distribution of securities
  convertible into or exercisable or exchangeable for Parent Common Stock or
  Company Common Stock), extraordinary cash dividend, reorganization,
  recapitalization, reclassification, combination, exchange of shares or
  other like change with respect to Parent Common Stock or Company Common
  Stock occurring or having a record date on or after the date hereof and
  prior to the Effective Time.

    (f) Fractional Shares. No fraction of a share of Parent Common Stock will
  be issued by virtue of the Merger, but in lieu thereof each holder of
  shares of Company Common Stock who would otherwise be entitled to receive a
  fraction of a share of Parent Common Stock (after aggregating all
  fractional shares of Parent Common Stock that otherwise would be received
  by such holder) shall, upon surrender of such holder's Certificates(s) (as
  defined in Section 1.7(c)) receive from Parent an amount of cash (rounded
  to the nearest whole cent), without interest, equal to the product of (i)
  such fraction, multiplied by (ii) the average closing price of one share of
  Parent Common Stock for the five (5) most recent days that Parent Common
  Stock has traded ending on the trading day immediately prior to the
  Effective Time, as reported on the Nasdaq National Market ("Nasdaq").

                                      A-7
<PAGE>

  1.7 Surrender of Certificates.

    (a) Exchange Agent. Prior to the Effective Time, Parent shall select a
  bank or trust company reasonably acceptable to Company to act as the
  exchange agent (the "Exchange Agent") in the Merger.

    (b) Parent to Provide Common Stock. Promptly after the Effective Time,
  Parent shall make available to the Exchange Agent for exchange in
  accordance with this Article I, the shares of Parent Common Stock issuable
  pursuant to Section 1.6(a) in exchange for outstanding shares of Company
  Common Stock, and cash in an amount sufficient for payment in lieu of
  fractional shares pursuant to Section 1.6(f) and any dividends or
  distributions to which holders of shares of Company Common Stock may be
  entitled pursuant to Section 1.7(d).

    (c) Exchange Procedures. As soon as practicable after the Effective Time,
  and in no event later than fifteen (15) days thereafter, Parent shall cause
  the Exchange Agent to mail to each holder of record (as of the Effective
  Time) of a certificate or certificates, which immediately prior to the
  Effective Time represented outstanding shares of Company Common Stock (the
  "Certificates") (i) a letter of transmittal in customary form (which shall
  specify that delivery shall be effected, and risk of loss and title to the
  Certificates shall pass, only upon delivery of the Certificates to the
  Exchange Agent and (ii) instructions for use in effecting the surrender of
  the Certificates in exchange for certificates representing shares of Parent
  Common Stock pursuant to Section 1.6(a), cash in lieu of any fractional
  shares pursuant to Section 1.6(f) and any dividends or other distributions
  pursuant to Section 1.7(d). Upon surrender of Certificates for cancellation
  to the Exchange Agent or to such other agent or agents as may be appointed
  by Parent, together with such letter of transmittal, duly completed and
  validly executed in accordance with the instructions thereto, the holders
  of such Certificates shall be entitled to receive in exchange therefor
  certificates representing the number of whole shares of Parent Common Stock
  into which their shares of Company Common Stock were converted pursuant to
  Section 1.6(a), payment in lieu of fractional shares which such holders
  have the right to receive pursuant to Section 1.6(f) and any dividends or
  other distributions payable pursuant to Section 1.7(d), and the
  Certificates so surrendered shall forthwith be canceled. Until so
  surrendered, outstanding Certificates will be deemed, from and after the
  Effective Time, to evidence only the ownership of the number of whole
  shares of Parent Common Stock into which such shares of Company Common
  Stock shall have been so converted (including any voting, notice or other
  rights associated with the ownership of such shares of Parent Common Stock
  under the Certificate of Incorporation or Bylaws of Parent or under
  Delaware Law) and the right to receive an amount in cash in lieu of the
  issuance of any fractional shares in accordance with Section 1.6(f) and any
  dividends or other distributions payable pursuant to Section 1.7(d).

    (d) Distributions With Respect to Unexchanged Shares. Dividends or other
  distributions declared or made after the date of this Agreement with
  respect to Parent Common Stock with a record date after the Effective Time
  will be paid to the holders of any unsurrendered Certificates with respect
  to the shares of Parent Common Stock represented thereby when the holders
  of record of such Certificates surrender such Certificates.

    (e) Transfers of Ownership. If certificates representing shares of Parent
  Common Stock are to be issued in a name other than that in which the
  Certificates surrendered in exchange therefor are registered, it will be a
  condition of the issuance thereof that the Certificates so surrendered will
  be properly endorsed and otherwise in proper form for transfer and that the
  persons requesting such exchange will have (i) paid to Parent or any agent
  designated by it any transfer or other taxes required by reason of the
  issuance of certificates representing shares of Parent Common Stock in any
  name other than that of the registered holder of the Certificates
  surrendered, or (ii) established to the satisfaction of Parent or any agent
  designated by it that such tax has been paid or is not payable.

    (f) Required Withholding. Each of the Exchange Agent, Parent and the
  Surviving Corporation shall be entitled to deduct and withhold from any
  consideration payable or otherwise deliverable

                                      A-8
<PAGE>

  pursuant to this Agreement to any holder or former holder of Company Common
  Stock such amounts as may be required to be deducted or withheld therefrom
  under the Code or state, local or foreign law. To the extent such amounts
  are so deducted or withheld, such amounts shall be treated for all purposes
  under this Agreement as having been paid to the person to whom such amounts
  would otherwise have been paid.

    (g) No Liability. Notwithstanding anything to the contrary in this
  Section 1.7, neither the Exchange Agent, Parent, the Surviving Corporation
  nor any party hereto shall be liable to a holder of shares of Parent Common
  Stock or Company Common Stock for any amount properly paid to a public
  official pursuant to any applicable abandoned property, escheat or similar
  law.

  1.8 No Further Ownership Rights in Company Common Stock. All shares of Parent
Common Stock issued in accordance with the terms hereof (including any cash
paid in respect thereof pursuant to Sections 1.6(f) and 1.7(d)) shall be deemed
to have been issued in full satisfaction of all rights pertaining to such
shares of Company Common Stock. There shall be no further registration of
transfers on the records of the Surviving Corporation of shares of Company
Common Stock which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article I.

  1.9 Lost, Stolen or Destroyed Certificates. In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent
shall issue and pay in exchange for such lost, stolen or destroyed
Certificates, upon the making of an affidavit of that fact by the holder
thereof, certificates representing the shares of Parent Common Stock into which
the shares of Company Common Stock represented by such Certificates were
converted pursuant to Section 1.6(a), cash for fractional shares, if any, as
may be required pursuant to Section 1.6(f) and any dividends or distributions
payable pursuant to Section 1.7(d); provided, however, that the Exchange Agent,
may, in its discretion and as a condition precedent to the issuance of such
certificates representing shares of Parent Common Stock and the payment of cash
and other distributions, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent, the Surviving
Corporation or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

  1.10 Tax and Accounting Consequences.

    (a) It is intended by the parties hereto that the Merger shall constitute
  a reorganization within the meaning of Section 368(a) of the Code. The
  parties hereto adopt this Agreement as a "plan of reorganization" within
  the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States
  Treasury Regulations. Accordingly, both prior to and after the Closing,
  each party's books and records shall be maintained and all federal, state
  and local income tax returns and schedules thereto shall be filed in a
  manner consistent with the Merger being qualified as a reverse triangular
  merger under Section 368(a)(2)(E) of the Code. Each party shall provide to
  each other such information, reports, returns or schedules as may be
  reasonably required to assist such party in accounting for and reporting
  the Merger being so qualified.

    (b) It is intended by the parties hereto that the Merger shall qualify as
  a pooling of interests for accounting purposes.

  1.11 Taking of Necessary Action; Further Action.  If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Company and Merger Sub, the officers and directors of Parent
and the Surviving Corporation shall be fully authorized (in the name of Merger
Sub, Company, the Surviving Corporation and otherwise) to take all such
necessary action.

    (b) Each Company Plan has been maintained and administered in all
  material respects in compliance with its terms and with the requirements

  trust intended to qualify under Section 501(a) of the Code (i) has either
  obtained a favorable determination, notification, advisory and/or opinion
  letter, as applicable, as to its qualified status from the IRS or still has
  a remaining period of time under applicable Treasury Regulations or IRS
  pronouncements in which to apply for such letter and to make any amendments
  necessary to obtain a favorable determination, and (ii) incorporates or has
  been amended to incorporate all provisions required to comply with the Tax
  Reform Act of 1986 and subsequent legislation. To the knowledge of Company,
  no condition or circumstance exists giving rise to a material likelihood
  that any such Company Plan would not be treated as qualified by the IRS.
  Company does not have any plan or commitment to establish any new Company
  Plan, to modify any Company Plan (except to the extent required by law or
  to conform any such Company Plan to the requirements of any applicable law,
  in each case as previously disclosed to Parent in writing, or as required
  by the terms of any Company Plan or this Agreement), or to enter into any
  new Company Plan. Each Company Plan can be amended, terminated or otherwise
  discontinued after the Effective Time in accordance with its terms, without
  liability to Parent, Company or any of its ERISA Affiliates (other than
  ordinary administration expenses).

    (c) Neither Company, any of its subsidiaries, nor any of their ERISA
  Affiliates has at any time ever maintained, established, sponsored,
  participated in, or contributed to any plan subject to Title IV of ERISA or
  Section 412 of the Code and at no time has Company contributed to or been
  requested to contribute to any "multiemployer plan," as such term is
  defined in ERISA. Neither Company, any of its subsidiaries, nor any officer
  or director of Company or any of its subsidiaries is subject to any
  material liability or penalty under Section 4975 through 4980B of the Code
  or Title I of ERISA. No "prohibited transaction," within the meaning of
  Section 4975 of the Code or Sections 406 and 407 of ERISA, and not
  otherwise exempt under Section 4975 of the Code and Section 408 of ERISA,
  has occurred with respect to any Company Plan which could subject Company
  or its ERISA Affiliates to material liability.

  other retiree welfare benefits to any person except as required by
  applicable law, and neither Company nor any of its subsidiaries has
  represented, promised or contracted (whether in oral or written form) to
  provide such retiree benefits to any Company Employee, former employee,
  director, consultant or other person, except to the extent required by
  statute.

    (e) Except as would not have a Material Adverse Effect, Company is in
  compliance in all material respects with all applicable material foreign,
  federal, state and local laws, rules and regulations respecting employment,
  employment practices, terms and conditions of employment and wages and
  hours.

    (f) Neither the execution and delivery of this Agreement nor the
  consummation of the transactions contemplated hereby will (i) result in any
  payment (including severance, unemployment compensation, golden parachute,
  bonus or otherwise) becoming due to any stockholder, director or Company
  Employee or any of its subsidiaries under any Company Plan or otherwise,
  (ii) materially increase any benefits otherwise payable under any Company
  Plan, or (iii) result in the acceleration of the time of payment or vesting
  of any such benefits.

  2.13 Absence of Liens and Encumbrances. Company and each of its subsidiaries

valid leasehold interests in, all of its material tangible properties and
assets, real, personal and mixed, used in its business, free and clear of any
liens or encumbrances except as reflected in the Company Financials and except
for liens for taxes not yet due and payable and such imperfections of title and
encumbrances, if any, which would not be material to Company.

  likely to result in a material liability to Company (in any individual case

  transported, stored, used, manufactured, disposed of, released or exposed
  its employees or others to pollutants, contaminants, wastes, any toxic,

  is pending or threatened against Parent or its subsidiaries, nor has any
  Governmental Entity indicated in writing an intention to conduct the same.

proceeding, claim, arbitration or investigation pending, or as to which Parent

  3.12 Employee Benefit Plans.

    (a) All employee compensation, incentive, fringe or benefit plans,
  programs, policies, commitments, agreements or other arrangements (whether
  or not set forth in a written document and including, without limitation,

  covering any active or former employee, director or consultant of Parent
  ("Parent Employee" which shall for this purpose mean an employee of Company
  or any ERISA Affiliate (as defined below)), any subsidiary of Parent or any
  trade or business (whether or not incorporated) which is an ERISA
  Affiliate, or with respect to which Parent has or, to its knowledge, may in
  the future have liability, are listed in Section 3.12(a) of the Parent
  Schedule (the "Parent Plans"). Parent has provided or will make available

    (b) Each Parent Plan has been maintained and administered in all material
  respects in compliance with its terms and with the requirements prescribed
  by any and all statutes, orders, rules and regulations (foreign or
  domestic), including but not limited to ERISA and the Code, which are
  applicable to such Parent Plans. No suit, action or other litigation
  (excluding claims for benefits incurred in the ordinary course of Parent
  Plan activities) has been brought, or to the knowledge of Parent, is
  threatened, against or with respect to any such Parent Plan. There are no
  audits, inquiries or proceedings pending or, to the knowledge of Parent,
  threatened by the IRS or the DOL with respect to any Parent Plans. All
  contributions, reserves or premium payments required to be made or accrued
  as of the date hereof to the Parent Plans have been timely made or accrued.
  Any Parent Plan intended to be qualified under Section 401(a) of the Code
  and each trust intended to qualify under Section 501(a) of the Code (i) has
  either obtained a favorable determination, notification, advisory and/or
  opinion letter, as applicable, as to its qualified status from the IRS or
  still has a remaining period of time under applicable Treasury Regulations
  or IRS pronouncements in which to apply for such letter and to make any
  amendments necessary to obtain a favorable determination, and (ii)
  incorporates or has been amended to incorporate all provisions required to
  comply with the Tax Reform Act of 1986 and subsequent legislation. To the
  knowledge of Parent, no condition or circumstance exists giving rise to a
  material likelihood that any such Parent Plan would not be treated as
  qualified by the IRS. Parent does not have any plan or commitment to
  establish any new Parent Plan, to modify any Parent Plan (except to the
  extent required by law or to conform any such Parent Plan to the
  requirements of any applicable law, in each case as previously disclosed to
  Company in writing, or as required by the terms of any Parent Plan or this
  Agreement), or to enter into any new Parent Plan. Each Parent Plan can be
  amended, terminated or otherwise discontinued after the Effective Time in
  accordance with its terms, without liability to Company, Parent or any of
  its ERISA Affiliates (other than ordinary administration expenses).

    (c) Neither Parent, any of its subsidiaries, nor any of their ERISA
  Affiliates has at any time ever maintained, established, sponsored,
  participated in, or contributed to any plan subject to Title IV of ERISA or
  Section 412 of the Code and at no time has Parent contributed to or been
  requested to contribute to any "multiemployer plan," as such term is
  defined in ERISA. Neither Parent, any of its subsidiaries, nor any officer
  or director of Parent or any of its subsidiaries is subject to any material
  liability or penalty under Section 4975 through 4980B of the Code or Title
  I of ERISA. No "prohibited transaction," within the meaning of Section 4975
  of the Code or Sections 406 and 407 of ERISA, and not otherwise exempt
  under Section 4975 of the Code and Section 408 of ERISA, has occurred with
  respect to any Parent Plan which could subject Parent or its ERISA
  Affiliates to material liability.

    (d) None of the Parent Plans promises or provides retiree medical or
  other retiree welfare benefits to any person except as required by
  applicable law, and neither Parent nor any of its subsidiaries has
  represented, promised or contracted (whether in oral or written form) to
  provide such retiree benefits to any Parent Employee, former employee,
  director, consultant or other person, except to the extent required by
  statute.

    (e) Except as would not have a Material Adverse Effect, Parent is in
  compliance in all material respects with all applicable material foreign,
  federal, state and local laws, rules and regulations respecting employment,
  employment practices, terms and conditions of employment and wages and
  hours.

    (f) Neither the execution and delivery of this Agreement nor the
  consummation of the transactions contemplated hereby will (i) result in any
  payment (including severance, unemployment compensation, golden parachute,
  bonus or otherwise) becoming due to any stockholder, director or Parent
  Employee or any of its subsidiaries under any Parent Plan or otherwise,
  (ii) materially increase any benefits otherwise payable under any Parent
  Plan, or (iii) result in the acceleration of the time of payment or vesting
  of any such benefits.

encumbrances, if any, which would not be material to Parent.

  its employees or others to Hazardous Materials in violation of any law in
  effect on or before the Closing Date, and (ii) neither Parent nor any of
  its subsidiaries has engaged in Hazardous Materials Activities in violation
  of any rule, regulation, treaty or statute promulgated by any Governmental

    (b) Environmental Liabilities. No action, proceeding, revocation
  proceeding, amendment procedure, writ, injunction or claim is pending, or
  to Parent's knowledge, threatened concerning any Parent Permit relating to
  any environmental matter, Hazardous Material or any Hazardous Materials
  Activity of Parent or any of its subsidiaries. Parent is not aware of any
  fact or circumstance which could involve Parent or any of its subsidiaries
  in any environmental litigation or impose upon Parent or any of its
  subsidiaries any environmental liability.

  3.15 Labor Matters. (i) There are no controversies pending or, to the

which could reasonably be expected to result in a cash payment obligation by
Parent in excess of $250,000; (ii) as of the date of this Agreement, neither
Parent nor any of its subsidiaries is a party to any collective bargaining
agreement or other labor union contract applicable to persons employed by
Parent or its subsidiaries nor does Parent or its subsidiaries know of any

  (i) the prospectus forming part of the registration statement on the S-4
  and (ii) the Joint Proxy Statement/Prospectus. Each of the parties hereto
  shall use all commercially reasonable efforts to cause the S-4 to become
  effective as promptly as practicable after the date hereof, and, prior to
  the effective date of the S- 4, the parties hereto shall take all action
  required under any applicable laws in connection with the issuance of
  shares of Parent Common Stock pursuant to the Merger. Each of Parent and
  Company shall provide promptly to the other such information concerning its
  business and financial statements and affairs as, in the reasonable
  judgment of the providing party or its counsel, may be required or
  appropriate for inclusion in the Joint Proxy Statement/Prospectus and the
  S-4, or in any amendments or supplements thereto, and cause its counsel and
  auditors to cooperate with the other's counsel and auditors in the
  preparation of the Joint Proxy Statement/Prospectus and the S-4. As
  promptly as practicable after the effective date of the S-4, the Joint
  Proxy Statement/Prospectus shall be mailed to the stockholders of Company
  and of Parent. Each of the parties hereto shall cause the Joint Proxy
  Statement/Prospectus to comply as to form and substance with respect to
  such party in all material respects with the applicable requirements of (i)
  the Exchange Act, (ii) the Securities Act, (iii) the rules and regulations
  of the Nasdaq. As promptly as practicable after the date of this Agreement,
  each of Company and Parent will prepare and file any other filings required
  to be filed by it under the Exchange Act, the Securities Act or any other
  Federal, foreign or Blue Sky or related laws relating to the Merger and the
  transactions contemplated by this Agreement (the "Other Filings"). Prior to
  the Effective Time, Parent shall use its commercially reasonable efforts to
  obtain all regulatory approvals needed to ensure that the Parent Common
  Stock to be issued in the Merger will be registered or qualified under the
  securities law of every jurisdiction in the United States in which any
  registered holder of Company Common Stock has an address of record on the
  record date for determining the stockholders entitled to notice of and to
  vote at the Company Stockholders' Meeting; provided that Parent shall not
  be required to consent generally to the service of process in any
  jurisdiction in which it is not so subject. Each of Company and Parent will
  notify the other promptly upon the receipt of any comments from the SEC or
  its staff or any other government officials of the receipt of notice that
  the S-4 has become effective, of the issuance of any stop order, of the
  suspension of the qualification of the Parent Common Stock issuable in
  connection with the Merger for offering or sale in any jurisdiction, or of
  any request by the SEC or its staff or any other government officials for
  amendments or supplements to the S-4, the Joint Proxy Statement/Prospectus
  or any Other Filing or for additional information and, except as may be
  prohibited by any Governmental Entity or by

                                      A-35
<PAGE>

  any Legal Requirement, will supply the other with copies of all
  correspondence between such party or any of its representatives, on the one
  hand, and the SEC or its staff or any other government officials, on the
  other hand, with respect to the S-4, the Joint Proxy Statement/Prospectus,
  the Merger or any Other Filing. Each of Company and Parent will cause all
  documents that it is responsible for filing with the SEC or other
  regulatory authorities under this Section 5.2(a) to comply in all material
  respects with all applicable requirements of law and the rules and
  regulations promulgated thereunder.

    (b) The Joint Proxy Statement/Prospectus shall (i) solicit the approval
  of this Agreement and the Merger and include the recommendation of the
  Board of Directors of Company to Company's stockholders that they vote in
  favor of approval of this Agreement and the Merger, subject to the right of
  the Board of Directors of Company to withdraw its recommendation and
  recommend a Superior Offer in compliance with Section 5.2(c) of this
  Agreement, and (ii) include the opinion of Merrill Lynch & Co. referred to
  in Section 2.19; provided, however, that the Board of Directors of Company
  shall submit this Agreement to Company's stockholders whether or not at any
  time subsequent to the date hereof such board determines that it can no
  longer make such recommendation. The Joint Proxy Statement/Prospectus shall
  (A) solicit the approval of the Share Issuance and include the
  recommendation of the Board of Directors of Parent to Parent's stockholders
  that they vote in favor of approval of the Share Issuance, and (B) include
  the opinion of Morgan Stanley & Co. Incorporated referred to in Section
  3.12. Nothing contained in this Agreement shall prevent the Board of
  Directors of Company from complying with Rule 14d-9 and Rule 14e-2 under
  the Exchange Act.

    (c) Each of Parent and Company shall promptly inform the other of any
  event which is required to be set forth in an amendment or supplement to
  the Joint Proxy Statement/Prospectus, the S-4 or any Other Filing and each
  of Parent and Company shall amend or supplement the Joint Proxy
  Statement/Prospectus to the extent required by law to do so. No amendment
  or supplement to the Joint Proxy Statement/Prospectus or the S-4 shall be
  made without the approval of Parent and Company, which approval shall not
  be unreasonably withheld or delayed. Each of the parties hereto shall
  advise the other parties hereto, promptly after it receives notice thereof,
  of the time when the S-4 has become effective or any supplement or
  amendment has been filed, of the issuance of any stop order, of the
  suspension of the qualification of the Parent Common Stock issuable in
  connection with the Merger for offering or sale in any jurisdiction, or of
  any request by the SEC for amendment of the Joint Proxy
  Statement/Prospectus or the S-4 or comments thereon and responses thereto
  or requests by the SEC for additional information.

  5.2 Stockholder Meetings.

    (a) Company shall call and hold the Company Stockholders' Meeting and
  Parent shall call and hold the Parent Stockholders' Meeting as promptly as
  practicable after the date hereof for the purpose of voting upon the
  approval of this Agreement and the Merger or the Share Issuance, as the
  case may be, pursuant to the Joint Proxy Statement/Prospectus, and Company
  and Parent shall use commercially reasonable efforts to hold the Company
  Stockholders' Meeting and the Parent Stockholders' Meeting on the same day
  and as soon as practicable after the date on which the S-4 becomes
  effective. Nothing herein shall prevent Company or Parent from adjourning
  or postponing the Company Stockholders' Meeting or the Parent Stockholders'
  Meeting, as the case may be, if there are insufficient shares of Company
  Common Stock or Parent Common Stock, as the case may be, necessary to
  conduct business at their respective meetings of the stockholders. Unless
  Company's Board of Directors has withdrawn its recommendation of this
  Agreement and the Merger in compliance with Section 5.2(c), Company shall
  use commercially reasonable efforts to solicit from its stockholders
  proxies in favor of the approval of this Agreement and the Merger pursuant
  to the Joint Proxy Statement/Prospectus and shall take all other action
  necessary or advisable to secure the vote or consent of stockholders
  required by Delaware Law or applicable stock exchange requirements to
  obtain such approval. Parent shall use commercially reasonable efforts to
  solicit from its stockholders proxies in favor of the Share Issuance
  pursuant to the Joint Proxy Statement/Prospectus and shall take all other
  action necessary or advisable to secure the

                                      A-36
<PAGE>

  vote or consent of stockholders required by Delaware Law or applicable
  stock exchange requirements to obtain such approval. Unless Company's Board
  of Directors has withdrawn its recommendation of this Agreement and the
  Merger in compliance with Section 5.2(c), each of the parties hereto shall
  take all other action reasonably necessary or advisable to promptly and
  expeditiously secure any vote or consent of stockholders required by
  applicable Law and such party's Certificate of Incorporation and Bylaws to
  effect the Merger. Company's obligation to call, give notice of, convene
  and hold the Company Stockholders' Meeting in accordance with this Section
  5.2(a) shall not be limited to or otherwise affected by the commencement,
  disclosure, announcement or submission to Company of any Acquisition
  Proposal or any change in the Board of Directors recommendation regarding
  the Merger.

    (b) Subject to Section 5.2(c): (i) the Board of Directors of Company
  shall recommend that Company's stockholders vote in favor of and adopt and
  approve this Agreement and the Merger at the Company Stockholders' Meeting;
  (ii) the Joint Proxy Statement/Prospectus shall include a statement to the
  effect that the Board of Directors of Company has recommended that
  Company's stockholders vote in favor of and adopt and approve this
  Agreement and the Merger at the Company Stockholders' Meeting; and (iii)
  neither the Board of Directors of Company nor any committee thereof shall
  withdraw, amend or modify, or propose or resolve to withdraw, amend or
  modify in a manner adverse to Parent, the recommendation of the Board of
  Directors of Company that Company's stockholders vote in favor of and adopt
  and approve this Agreement and the Merger.

    (c) Nothing in this Agreement shall prevent the Board of Directors of
  Company from withholding, withdrawing, amending or modifying its
  recommendation in favor of adopting and approving this Agreement and the
  Merger or from not including its recommendation in favor of adopting and
  approving this Agreement and the Merger in the Joint Proxy
  Statement/Prospectus if (i) a Superior Offer (as defined below) is made to
  Company and not withdrawn, (ii) neither Company nor any of its
  representatives shall have violated any of the restrictions set forth in
  Section 5.4 and Company is not then in breach of this Agreement, and (iii)
  the Board of Directors of Company concludes in good faith, after
  consultation with and receiving advice from its outside counsel, that, in
  light of such Superior Offer, the withholding, withdrawal, amendment or
  modification of such recommendation is necessary in order for the Board of
  Directors of Company to comply with its fiduciary obligations to Company's
  stockholders under applicable law; provided, however, that prior to any
  commencement thereof Company shall have given Parent at least forty eight
  (48) hours notice thereof and the opportunity to meet with Company and its
  counsel. Nothing contained in this Section 5.2 shall limit Company's
  obligation to hold and convene the Company Stockholders' Meeting
  (regardless of whether the recommendation of the Board of Directors of
  Company shall have been withdrawn, amended or modified). For purposes of
  this Agreement, "Superior Offer" shall mean an unsolicited, bona fide
  written offer made by a third party to consummate any of the following
  transactions: (i) a merger, consolidation, business combination,
  recapitalization, liquidation, dissolution or similar transaction involving
  Company pursuant to which the stockholders of Company immediately preceding
  such transaction hold less than 51% of the equity interest in the surviving
  or resulting entity of such transaction; (ii) a sale or other disposition
  by Company of assets (excluding inventory and used equipment sold in the
  ordinary course of business) representing in excess of 51% of the fair
  market value of Company's business immediately prior to such sale, or (iii)
  the acquisition by any person or group (including by way of a tender offer
  or an exchange offer or issuance by Company), directly or indirectly, of
  beneficial ownership or a right to acquire beneficial ownership of shares
  representing in excess of 51% of the voting power of the then outstanding
  shares of capital stock of Company, in each case on terms that the Board of
  Directors of Company determines, in its reasonable judgment (based on
  written advice of a financial advisor of nationally recognized reputation)
  to be more favorable to Company stockholders from a financial point of view
  than the terms of the Merger; provided, however, that any such offer shall
  not be deemed to be a "Superior Offer" if any financing required to
  consummate the transaction contemplated by such offer is not committed and
  is not likely in the judgment of Company's Board of Directors to be
  obtained by such third party on a timely basis.

  termination of this Agreement pursuant to Article VII, Company and its
  subsidiaries will not, nor will they authorize or permit any of their

  banker, attorney or other advisor or representative retained by any of them
  to, directly or indirectly (i) solicit, initiate, encourage or induce the
  making, submission or announcement of any Acquisition Proposal (as defined
  below), (ii) participate in any discussions or negotiations regarding, or

  with, any person or group in response to a Superior Offer submitted by such
  person or group (and not withdrawn), (B) taking the actions described in

  and its subsidiaries shall have violated any of the restrictions set forth
  in this Section 5.4, (2) the Board of Directors of Company concludes in
  good faith, after consultation with its outside legal counsel, that such
  action is necessary in order for the Board of Directors of Company to
  comply with its fiduciary obligations to Company's stockholders under
  applicable law, (3) (x) at least two business days prior to furnishing any
  such nonpublic information to, or entering into discussions or negotiations
  with, such person or group, Company gives Parent written notice of the
  identity of such person or group and of Company's intention to furnish

<PAGE>

  (4) contemporaneously with furnishing any such information to such person
  or group, Company furnishes such information to Parent (to the extent such
  information has not been previously furnished by Company to Parent).
  Nothing in this Section 5.4(a) shall prevent Company or its Board of
  Directors from complying with Rule 14e-2 promulgated under the Exchange Act
  with regard to an Acquisition Proposal with respect to which no violation
  of this Section 5.4 shall have occurred. Company and its subsidiaries will
  immediately cease any and all existing activities, discussions or
  negotiations with any parties conducted heretofore with respect to any
  Acquisition Proposal. Without limiting the foregoing, it is understood that
  any violation of the restrictions set forth in the preceding two sentences
  by any officer or director of Company or any of its subsidiaries or any
  investment banker, attorney or other advisor or representative of Company
  or any of its subsidiaries shall be deemed to be a breach of this Section
  5.4 by Company. In addition to the foregoing, Company shall (i) provide
  Parent with at least twenty four (24) hours prior notice (or such lesser
  prior notice as provided to the members of Company's Board of Directors) of
  any meeting of Company's Board of Directors at which Company's Board of
  Directors is reasonably expected to consider a Superior Offer.

Section 13(d) of the Exchange Act and the rules and regulations thereunder) of
more than a 15% interest in the total outstanding voting securities of Company
or any of its subsidiaries or any tender offer or exchange offer that if
consummated would result in any person or "group" (as defined under Section
13(d) of the Exchange Act and the rules and regulations thereunder)
beneficially owning 15% or more of the total outstanding voting securities of
Company or any of its subsidiaries or any merger, consolidation, business
combination or similar transaction involving Company pursuant to which the
stockholders of Company immediately preceding such transaction hold less than
85% of the equity interests in the surviving or resulting entity of such
transaction; (B) any sale, lease (other than in the ordinary course of
business), exchange, transfer, license (other than in the ordinary course of
business), acquisition or disposition of more than 15% of the assets of
Company; or (C) any liquidation or dissolution of Company.

    (b) In addition to the obligations of Company set forth in paragraph (a)
  of this Section 5.4, Company as promptly as practicable shall advise Parent
  orally and in writing of any request received by Company for information
  which Company reasonably believes would lead to an Acquisition Proposal or
  of any Acquisition Proposal, or any inquiry received by Company with
  respect to, or which Company reasonably believes would lead to any
  Acquisition Proposal, the material terms and conditions of such request,
  Acquisition Proposal or inquiry, and the identity of the person or group
  making any such request, Acquisition Proposal or inquiry. Company will keep
  Parent informed in all material respects of the status and details
  (including material amendments or proposed amendments) of any such request,
  Acquisition Proposal or inquiry.

to the extent practicable, agree, before issuing any press release or otherwise
making any public statement with respect to the Merger, this Agreement or an
Acquisition Proposal and will not issue any such press release or make any such
public statement prior to such consultation, except as may be required by law
or any listing agreement with a national securities exchange or Nasdaq, in
which case reasonable efforts to consult with the other party will be made
prior to such release or public statement. The parties have agreed to the text
of the joint press release announcing the signing of this Agreement.

  5.6 Commercially Reasonable Efforts; Notification.

    (a) Upon the terms and subject to the conditions set forth in this
  Agreement, each of the parties agrees to use reasonable commercially
  reasonable efforts to take, or cause to be taken, all actions, and to do,
  or cause to be done, and to assist and cooperate with the other parties in
  doing, all things

                                      A-39
<PAGE>

  necessary, proper or advisable to consummate and make effective, in the
  most expeditious manner practicable, the Merger and the other transactions
  contemplated by this Agreement, including to accomplish the following: (i)
  causing the conditions precedent set forth in Article VI to be satisfied;
  (ii) obtaining all necessary actions or nonactions, waivers, consents,
  approvals, orders and authorizations from Governmental Entities; (iii)
  making all necessary registrations, declarations and filings (including
  registrations, declarations and filings with Governmental Entities, if
  any); (iv) avoiding any suit, claim, action, investigation or proceeding by
  any Governmental Entity challenging the Merger or any other transaction
  contemplated by this Agreement; (v) obtaining all consents, approvals or
  waivers from third parties required as a result of the transactions
  contemplated in this Agreement; (vi) defending any suits, claims, actions,
  investigations or proceedings, whether judicial or administrative,
  challenging this Agreement or the consummation of the transactions
  contemplated hereby, including seeking to have any stay or temporary
  restraining order entered by any court or other Governmental Entity vacated
  or reversed; and (vii) executing or delivering any additional instruments
  reasonably necessary to consummate the transactions contemplated by, and to
  fully carry out the purposes of, this Agreement. In connection with and
  without limiting the foregoing, subject to the other terms and conditions
  hereof, Company and its Board of Directors shall, if any state takeover
  statute or similar statute or regulation is or becomes applicable to the
  Merger, this Agreement or any of the transactions contemplated by this
  Agreement, use commercially reasonable efforts and take all acts necessary
  to ensure that the Merger and the other transactions contemplated by this
  Agreement may be consummated as promptly as practicable on the terms
  contemplated by this Agreement and otherwise to minimize the effect of such
  statute or regulation on the Merger, this Agreement and the transactions
  contemplated hereby. Notwithstanding anything herein to the contrary,
  nothing in this Agreement shall be deemed to require Parent or Company or
  any subsidiary or affiliate thereof to agree to any divestiture by itself
  or any of its affiliates of shares of capital stock or of any business,
  assets or property, or the imposition of any material limitation on the
  ability of any of them to conduct their business or to own or exercise
  control of such assets, properties and stock.

    (b) Company shall give prompt notice to Parent upon becoming aware that
  any representation or warranty made by it contained in this Agreement has
  become untrue or inaccurate, or of any failure of Company to comply with or
  satisfy in any material respect any covenant, condition or agreement to be
  complied with or satisfied by it under this Agreement, in each case, where
  the conditions set forth in Section 6.3(a) or Section 6.3(b) would not be
  satisfied as a result thereof; provided, however, that no such notification

    (a) Stock Options. At the Effective Time, each outstanding option to
  purchase shares of Company Common Stock (each, a "Company Stock Option")
  under the Company Option Plans, whether or not vested, shall be assumed by
  Parent. Each Company Stock Option so assumed by Parent

                                      A-40
<PAGE>

  under this Agreement will continue to have, and be subject to, the same
  terms and conditions of such Company Stock Options immediately prior to the
  Effective Time (including, without limitation, any repurchase rights or
  vesting provisions and provisions regarding the acceleration of vesting on
  certain transactions, other than the transactions contemplated by this
  Agreement), except that (i) each Company Stock Option will be exercisable
  (or will become exercisable in accordance with its terms) for that number
  of whole shares of Parent Common Stock equal to the product of the number
  of shares of Company Common Stock that were issuable upon exercise of such
  Company Stock Option immediately prior to the Effective Time multiplied by
  the Exchange Ratio, rounded down to the nearest whole number of shares of
  Parent Common Stock and (ii) the per share exercise price for the shares of
  Parent Common Stock issuable upon exercise of such assumed Company Stock
  Option will be equal to the quotient determined by dividing the exercise
  price per share of Company Common Stock at which such Company Stock Option
  was exercisable immediately prior to the Effective Time by the Exchange
  Ratio, rounded up to the nearest whole cent. Parent shall comply with the
  terms of all such Company Stock Options and use its best efforts to ensure,
  to the extent required by and subject to the provisions of, the Company
  Option Plans, and to the extent permitted under the Code, that any Company
  Stock Options that qualified for tax treatment as incentive stock options
  under Section 422 of the Code prior to the Effective Time continue to so
  qualify after the Effective Time. Parent shall take all corporate actions
  necessary to reserve for issuance a sufficient number of shares of Parent
  Common Stock for delivery upon exercise of assumed Company Stock Options on
  the terms set forth in this Section 5.8 (a).

    (b) ESPP. As of the Effective Time, the ESPP shall be terminated. The
  rights of participants in the ESPP with respect to any offering period then
  underway under the ESPP shall be determined by treating the last business
  day prior to the Effective Time as the last day of such offering period and
  by making such other pro rata adjustments as may be necessary to reflect
  the shortened offering period but otherwise treating such shortened
  offering period as a fully effective and completed offering period for all
  purposes under the ESPP. Prior to the Effective Time, Company shall take
  all commercially reasonable actions (including but not limited to, if
  appropriate, amending the ESPP) that are necessary to give effect to the
  transaction contemplated by this Section 5.8(b). As of the Effective Time,
  participants in the ESPP ("ESPP Participants") shall become participants in
  Parent's Employee Stock Purchase Plan ("Parent ESPP"). An offering period
  for the ESPP Participant's under the Parent ESPP shall begin as of the
  Effective Time and continue through January 31, 2000. As of February 1,
  2000, ESPP Participants will proceed with participation in Parent's ESPP
  according to the provisions of the Parent ESPP. Prior to the Effective
  Time, Parent shall take commercially reasonable efforts (including, but not
  limited to, if required, amending the Parent ESPP) that are necessary to
  give effect to the transaction contemplated by this Section 5.8(b).

    (c) 401(k). Company shall terminate, effective as of the day immediately
  preceding the Effective Time, any and all 401(k) plans sponsored or
  maintained by Company unless Parent provides written notice to Company
  prior to the Effective Time that any such 401(k) plan shall not be
  terminated. Parent shall receive from Company evidence that Company's
  plan(s) and / or program(s) have been terminated pursuant to resolutions of
  Company's Board of Directors (the form and substance of such resolutions
  shall be subject to review and approval of Parent), effective as of the day
  immediately preceding the Effective Time. Company employees shall be
  eligible to participate in a 401(k) plan sponsored by Parent as soon as
  administratively practicable after the Effective Time.

    (d) Benefits; Prior Service. From and after the Effective Time, Company
  employees shall be provided with employee benefits that are the same as
  those provided to employees of Parent who are similarly situated. Parent
  shall cause employees of Company and its subsidiaries to be credited with
  service with Company and each of its subsidiaries for purposes of
  eligibility, vesting and accrual of vacation days, personal days and sick
  leave under each employee benefit plan maintained by Parent or its
  subsidiaries prior to the Effective Time. Parent shall have the absolute
  discretion to (i) cash-out Company employees accrued and unused vacation,
  personal and sick leave days or to (ii) carry over

                                      A-41
<PAGE>

  Company employees' accrued but unused vacation, personal and sick leave
  days; provided, that, such service shall not be recognized to the extent
  that such recognition would result in duplication of benefits.

  5.9 Form S-8. Parent agrees to file a registration statement on Form S-8 for
the shares of Parent Common Stock issuable with respect to assumed Company
Stock Options as soon as is reasonably practicable, and in any event within
three (3) business days, after the Effective Time. Prior to Closing, Company
shall use commercially reasonable efforts to provide Parent with all
information required or reasonably requested by Parent to be included in the
Form S-8.

  5.10 Indemnification.

    (a) From and after the Effective Time, Parent will cause the Surviving
  Corporation to fulfill and honor in all respects the obligations of Company
  (or any predecessor corporation) pursuant to (i) each indemnification
  agreement between Company and its directors or officers in effect
  immediately prior to the Effective Time (the "Indemnified Parties") and
  (ii) any indemnification provision under the Company Charter Documents as
  in effect on the date hereof. The Certificate of Incorporation and Bylaws
  of the Surviving Corporation will contain provisions with respect to
  exculpation and indemnification that are at least as favorable to the
  Indemnified Parties as those contained in the Company Charter Documents as
  in effect on the date hereof, which provisions will not be amended,
  repealed or otherwise modified for a period of six (6) years from the
  Effective Time in any manner that would adversely affect the rights
  thereunder of any Indemnified Party or of individuals who, immediately
  prior to the Effective Time, were employees or agents of Company, unless
  such modification is required by law.

    (b) For a period of six (6) years after the Effective Time, Surviving
  Corporation shall, and Parent shall cause Surviving Corporation to maintain
  in effect policies of directors' and officers' liability insurance with
  coverage in amount and scope at least as favorable as Company's existing
  policies with respect to claims arising from facts or events that occurred
  prior to the Effective Time; provided, however, that during such period,
  Surviving Corporation shall in no event be required to expend pursuant to
  this Section 5.10(b) more than an amount per year equal to 150% of current
  premiums paid by Company for such insurance, which current premium amount
  is set forth in Section 5.10(b) of the Company Disclosure Schedule.

  respective successors or assigns (i) consolidates with or merges into any
  other person and shall not be the continuing or surviving corporation or
  entity of such consolidation or merger or (ii) transfers a material amount
  of its properties and assets to any person in a single transaction or a
  series of transactions, then, and in each such case, Parent will make or
  cause to be made proper provision so that the successors and assigns of
  Company or the Surviving Corporation, as the case may be, assume the
  indemnification obligations described herein for the benefit of the
  Indemnified Parties.

    (d) The provisions of this Section 5.10 shall survive the Effective Time
  and are (i) intended to be for the benefit of, and will be enforceable by,

  provide Parent with such information and documents as Parent reasonably
  requests for purposes of reviewing such list. Company will use its

  Stock, consistent with the terms of the Company Affiliate Agreement.

comparable pre-merger notification forms required by the merger notification or
control laws and regulations of any other applicable jurisdiction, as agreed to
by the parties. Company and Parent each shall each use all reasonable efforts
to obtain early termination of any waiting period under HSR and Company and

of Parent's subsidiaries or affiliates of shares of capital stock or of any
business, assets or property of Parent or its subsidiaries or affiliates or of
Company, its affiliates, or the imposition of any material limitation on the
ability of any of them to conduct their businesses or to own or exercise
control of such assets, properties and stock.

  5.13 Action by Board of Directors. Prior to the Effective Time, the Board of

thereof, shall adopt a resolution consistent with the interpretative guidance
of the SEC so that (i) the assumption of Company Stock Options by Company
Insiders (as defined below) pursuant to this Agreement, and (ii) the receipt by
Company Insiders of Parent Common Stock in exchange for Company Common Stock
pursuant to the Merger, shall in each case be an exempt transaction for
purposes of Section 16 of the Exchange Act by any officer or director of
Company who may become a covered person of Parent for purposes of Section 16 of
the Exchange Act (a "Company Insider").

  5.14 Parent of Board of Directors. Prior to the Effective Time, the Board of

for so long as he serves as an employee of Parent and (B) Mr. Savoy's
designation (or any replacement designated by Vulcan Ventures Incorporated) for
so long as Vulcan

                                      A-43

    (a) Company shall use all commercially reasonable efforts to receive from
  KPMG LLP, independent auditors for Company, a copy of a letter addressed to
  Company dated as of the Closing Date in substance reasonably satisfactory
  to Parent (which may contain customary qualifications and assumptions) to
  the effect that KPMG LLP concurs with Company management's conclusion that
  no conditions exist related to Company that would preclude Company from
  being a party to a business combination for which the "pooling-of-interest"
  method of accounting is used.

    (b) Parent shall use all commercially reasonable efforts to receive from
  Deloitte & Touche LLP, independent accountants for Parent, a copy of a
  letter addressed to Parent dated as of the Closing Date in substance

(i) to take any action (or to cause the Surviving Company or any Affiliate of
Parent or Merger Sub to take any action), and (ii) to fail to take any action
(or to cause the Surviving Company or any Affiliates of Parent or Merger Sub
not to fail to take any action), which if taken or not taken, as the case may
be, would reasonably be expected to prevent, the Merger from qualifying as a
reorganization within the meaning of Section 368(a) of the Code.

  employees of Parent and its subsidiaries who have not already entered into
  Parent's standard form of Non-Disclosure, Invention Release and Non-
  Competition Agreement to enter into such agreement prior to the Closing.

  Parent of written notice of such determination of Company (which written
  notice will inform Parent of the material terms and conditions of the
  Superior Offer); provided, further, that such termination under this
  Section 7.1(h) shall not be effective until Company has made payment to
  Parent of the amounts required to be paid pursuant to Section 7.3(b)(i).

  7.2 Notice of Termination; Effect of Termination. Any termination of this
Agreement under Section 7.1 will be effective immediately upon (or if the
termination is pursuant to Section 7.1(e) or 7.1(f) and the proviso therein is
applicable, thirty (30) days after) the delivery of written notice thereof by
the terminating party to the other parties hereto. In the event of the
termination of this Agreement as provided in Section 7.1, this Agreement shall
be of no further force or effect, with no liability of either party to the
other, except (i) as set forth in this Section 7.2, Section 7.3 and Article 8
(General Provisions), each of which shall survive the termination of this
Agreement, and (ii) nothing herein shall relieve any party from liability for
any intentional or willful breach of this Agreement. No termination of this
Agreement shall affect the obligations of the parties contained in the
Confidentiality Agreement, all of which obligations shall survive termination
of this Agreement in accordance with their terms.

  7.3 Fees and Expenses.

    (a) General. Except as set forth in this Section 7.3, all fees and
  expenses incurred in connection with this Agreement and the transactions
  contemplated hereby shall be paid by the party incurring such fees and
  expenses whether or not the Merger is consummated; provided, however, that
  Parent and Company shall share equally all fees and expenses, other than
  attorneys' and accountants fees and expenses, incurred in connection with
  the printing and filing (with the SEC) of the Joint Proxy
  Statement/Prospectus (including any preliminary materials related thereto)
  and the S-4 (including financial statements and exhibits) and any
  amendments or supplements thereto and any fees required to be paid under
  the HSR Act.

    (b) Company Payments.

      (i) Company shall pay to Parent in immediately available funds,
    within one (1) business day after demand by Parent (or prior to, and a
    condition to the effectiveness of, termination of this Agreement
    pursuant to Section 7.1(h)), an amount equal to $120,000,000 (the
    "Termination Fee") if this Agreement is terminated by Parent pursuant
    to Section 7.1(g) or by Company pursuant to Section 7.1(h).

      (ii) If (A) this Agreement is terminated by Parent or Company, as
    applicable, pursuant to Sections 7.1(b) or (d)(i), (B) prior to such
    termination a third party shall have announced an Acquisition Proposal
    and (C) within twelve (12) months following the termination of this
    Agreement a Company Acquisition (as defined below) is consummated or
    Company enters into an agreement or binding letter of intent providing
    for a Company Acquisition, then Company shall pay Parent in immediately
    available funds at or prior to consummating such Company Acquisition an
    amount equal to the Termination Fee.

      (iii) Company acknowledges that the agreements contained in this
    Section 7.3(b) are an integral part of the transactions contemplated by
    this Agreement, and that, without these agreements, Parent would not
    enter into this Agreement; accordingly, if Company fails to pay in a
    timely manner the amounts due pursuant to this Section 7.3(b) and, in
    order to obtain such payment, Parent makes a claim that results in a
    judgment against Company for the amounts set forth in this Section
    7.3(b), Company shall pay to Parent its reasonable costs and expenses
    (including reasonable attorneys' fees and expenses) in connection with
    such suit, together with interest on the amounts set forth in this
    Section 7.3(b) at the prime rate of Citibank, N.A. in effect on the
    date such payment was required to be made. Payment of the fees
    described in this Section 7.3(b) shall not be in lieu of damages
    incurred in the event of breach of this Agreement. For the purposes of
    this Agreement, "Company Acquisition" shall mean any of the following
    transactions (other than the transactions contemplated by this
    Agreement): (i) a merger,

                                      A-48
<PAGE>

    consolidation, business combination, recapitalization, liquidation,
    dissolution or similar transaction involving Company pursuant to which
    the stockholders of Company immediately preceding such transaction hold
    less than 60% of the aggregate equity interests in the surviving or
    resulting entity of such transaction, (ii) a sale or other disposition
    by Company of assets representing in excess of 60% of the aggregate
    fair market value of Company's business immediately prior to such sale
    or (iii) the acquisition by any person or group (including by way of a
    tender offer or an exchange offer or issuance by Company), directly or
    indirectly, of beneficial ownership or a right to acquire beneficial
    ownership of shares representing in excess of 50% of the voting power
    of the then outstanding shares of capital stock of Company.

  7.4 Amendment. Subject to applicable law, this Agreement may be amended by
the parties hereto at any time by execution of an instrument in writing signed
on behalf of each of Parent and Company.

  7.5 Extension; Waiver. At any time prior to the Effective Time, any party
hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties
hereto, (ii) waive any inaccuracies in the representations and warranties made
to such party contained herein or in any document delivered pursuant hereto and
(iii) waive compliance with any of the agreements or conditions for the benefit
of such party contained herein. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party. Delay in exercising any right under
this Agreement shall not constitute a waiver of such right.

  8.5 Entire Agreement; Third Party Beneficiaries. This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Company Schedule and the
Parent Schedule (a) constitute the entire agreement among the parties with

  8.6 Severability. In the event that any provision of this Agreement, or the
application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as
reasonably to effect the intent of the parties hereto. The parties further
agree to replace such void or unenforceable provision of this Agreement with a
valid and enforceable provision that will achieve, to the extent possible, the
economic, business and other purposes of such void or unenforceable provision.

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 seek an injunction or injunctions to prevent
breaches of this Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having jurisdiction, this

suit shall be entitled to receive a reasonable sum for its attorneys' fees and

rights, interests, or obligations hereunder without the prior written approval
of the other parties. Subject to the preceding sentence, this Agreement shall
be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

                            COMPANY VOTING AGREEMENT

  THIS VOTING AGREEMENT (this "Agreement") is made and entered into as of July
26, 2000, among INFOSPACE, INC., a Delaware corporation ("Parent"), and the
undersigned stockholder (the "Stockholder") of Go2Net, INC., a Delaware

                                    RECITALS

  A. The Company, Merger Sub (as defined below) and Parent have entered into an
Agreement and Plan of Reorganization of even date herewith (the "Reorganization
Agreement"), which provides for the merger (the "Merger") of Giants Acquisition
Corp., a wholly-owned subsidiary of Parent ("Merger Sub"), with and into the
Company. Pursuant to the Merger, all outstanding capital stock of the Company
shall be converted into common stock of Parent, as set forth in the
Reorganization Agreement;

  B. Stockholder is the beneficial owner (as defined in Rule 13d-3 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) of such
number of shares of the outstanding capital stock of the Company and shares
subject to outstanding options as is indicated on the signature page of this
Agreement; and

  C. In consideration of the execution of the Reorganization Agreement by
Parent, Stockholder (in his or her capacity as such) agrees to vote the Shares
(as defined below) and other such shares of capital stock of the Company over
which Stockholder has voting power so as to facilitate consummation of the
Merger.

  NOW, THEREFORE, intending to be legally bound, the parties hereto agree as
follows:

  1. Certain Definitions. Capitalized terms not defined herein shall have the
meanings ascribed to them in the Reorganization Agreement. For purposes of this
Agreement:

    (a) "Expiration Date" shall mean the earlier to occur of (i) such date
  and time as the Reorganization Agreement shall have been terminated
  pursuant to Article VII thereof, or (ii) such date and time as the Merger
  shall become effective in accordance with the terms and provisions of the
  Reorganization Agreement.

    (b) "Person" shall mean any (i) individual, (ii) corporation, limited
  liability company, partnership or other entity, or (iii) governmental
  authority.

    (c) "Shares" shall mean: (i) all securities of the Company (including all
  shares of Company Common Stock, Company Preferred Stock and all options,
  warrants and other rights to acquire shares of Company Common Stock and
  Company Preferred Stock) owned by Stockholder as of the date of this
  Agreement; and (ii) all additional securities of the Company (including all
  additional shares of Company Common Stock and Company Preferred Stock and
  all additional options, warrants and other rights to acquire shares of
  Company Common Stock and Company Preferred Stock) of which Stockholder
  acquires ownership during the period from the date of this Agreement
  through the Expiration Date.

    (d) Transfer. A Person shall be deemed to have effected a "Transfer" of a
  security if such person directly or indirectly: (i) sells, pledges,
  encumbers, grants an option with respect to, transfers or disposes of such
  security or any interest in such security; or (ii) enters into an agreement
  or commitment providing for the sale of, pledge of, encumbrance of, grant
  of an option with respect to, transfer of or disposition of such security
  or any interest therein.

  2. Transfer of Shares.

    (a) Transferee of Shares to be Bound by this Agreement. Stockholder
  agrees that, during the period from the date of this Agreement through the
  Expiration Date, Stockholder shall not cause or

                                    A-A-1-1
<PAGE>

  permit any Transfer of any of the Shares to be effected unless each Person
  to which any of such Shares, or any interest in any of such Shares, is or
  may be transferred shall have: (a) executed a counterpart of this Agreement
  and a proxy in the form attached hereto as Exhibit A (with such
  modifications as Parent may reasonably request); and (b) agreed in writing
  to hold such Shares (or interest in such Shares) subject to all of the
  terms and provisions of this Agreement.

    (b) Transfer of Voting Rights. Stockholder agrees that, during the period
  from the date of this Agreement through the Expiration Date, Stockholder
  shall not deposit (or permit the deposit of) any Shares in a voting trust
  or grant any proxy or enter into any voting agreement or similar agreement
  in contravention of the obligations of Stockholder under this Agreement
  with respect to any of the Shares.

  3. Agreement to Vote Shares. At every meeting of the stockholders of the
Company called, and at every adjournment thereof, and on every action or
approval by written consent of the stockholders of the Company, Stockholder (in
his or her capacity as such) shall cause the Shares to be voted in favor of
adoption of the Reorganization Agreement. Notwithstanding any provision of this
Agreement to the contrary, nothing in this Agreement shall limit or restrict
Stockholder from acting in Stockholder's capacity as a director or officer of
Company (it being understood that this Agreement shall apply to Stockholder
solely in Stockholder's capacity as a stockholder of Company) or voting in
Stockholder's sole discretion on any matter other than those matters referred
to in the preceding sentence.

  4. Irrevocable Proxy. Concurrently with the execution of this Agreement,
Stockholder agrees to deliver to Parent a proxy in the form attached hereto as
Exhibit A (the "Proxy"), which shall be irrevocable to the fullest extent
permissible by law, with respect to the Shares.

beneficial owner of the shares of Company Common Stock and Company Preferred

adverse claims, charges or other encumbrances (except any such encumbrances
arising under securities laws); (ii) does not beneficially own any securities
of the Company other than the shares of Company Common Stock, shares of Company
Preferred Stock and options to purchase shares of Company Common Stock
indicated on the signature page of this Agreement; and (iii) has full power and
authority to make, enter into and carry out the terms of this Agreement and the
Proxy.

  6. Additional Documents. Stockholder (in his or her capacity as such) and
Parent hereby covenant and agree to execute and deliver any additional
documents necessary or desirable, in the reasonable opinion of Parent, to carry
out the intent of this Agreement.

  7. Legending of Shares. If so requested by Parent, Stockholder agrees that
the Shares shall bear a legend stating that they are subject to this Agreement
and to an irrevocable proxy.

  8. Termination. This Agreement and the Proxy delivered in connection herewith
shall terminate and shall have no further force or effect as of the Expiration
Date.

  9. Miscellaneous.

    (a) Severability. If any term, provision, covenant or restriction of this
  Agreement is held by a court of competent jurisdiction to be invalid, void
  or unenforceable, then the remainder of the terms, provisions, covenants
  and restrictions of this Agreement shall remain in full force and effect
  and shall in no way be affected, impaired or invalidated.

    (b) Binding Effect and Assignment. This Agreement and all of the
  provisions hereof shall be binding upon and inure to the benefit of the
  parties hereto and their respective successors and

                                    A-A-1-2

  amended, altered or supplemented except upon the execution and delivery of
  a written agreement executed by the parties hereto.

    (d) Specific Performance; Injunctive Relief. The parties hereto
  acknowledge that Parent shall be irreparably harmed and that there shall be
  no adequate remedy at law for a violation of any of the covenants or
  agreements of Stockholder set forth herein. Therefore, it is agreed that,
  in addition to any other remedies that may be available to Parent upon any
  such violation, Parent shall have the right to enforce such covenants and
  agreements by specific performance, injunctive relief or by any other means
  available to Parent at law or in equity.

  Agreement shall be in writing and deemed to be sufficient if contained in a

Stockholder has voting power so as to facilitate consummation of the Merger.

  NOW, THEREFORE, intending to be legally bound, the parties hereto agree as

meanings ascribed to them in the Reorganization Agreement. For purposes of this
Agreement:

    (a) "Expiration Date" shall mean the earlier to occur of (i) such date

nothing in this Agreement shall limit or restrict Stockholder from acting in

as a stockholder of Parent) or voting in Stockholder's sole discretion on any
matter other than those matters referred to in the preceding sentence.

                          STOCK OPTION AGREEMENT

  THIS STOCK OPTION AGREEMENT (this "Agreement") is made and entered into as of
July 26, 2000, among InfoSpace, Inc., a Delaware corporation ("Parent"), and
Go2Net, Inc., a Delaware corporation (the "Company"). Capitalized terms used
but not otherwise defined herein will have the meanings ascribed to them in the
Reorganization Agreement (as defined below).

                                    RECITALS

  A. The Company, Merger Sub (as defined below) and Parent have entered into an
Agreement and Plan of Reorganization (the "Reorganization Agreement") which
provides for the merger (the "Merger") of a wholly-owned subsidiary of Parent
("Merger Sub") with and into the Company. Pursuant to the Merger, all
outstanding capital stock of the Company will be converted into the right to
receive Parent Common Stock.

  B. As a condition to Parent's willingness to enter into the Reorganization
Agreement, Parent has requested that Company agree, and Company has so agreed,
to grant to Parent an option to acquire shares of Company's Common Stock, $.01
par value per share (the "Company Shares"), upon the terms and subject to the
conditions set forth herein.

  NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants
and agreements set forth herein and in the Reorganization Agreement and for
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto agree as follows:

  1. Grant of Option. The Company hereby grants to Parent an irrevocable option
(the "Option") to acquire up to a number of Company Shares equal to 19.9% of
the issued and outstanding shares as of the date of this Agreement (the "Option
Shares"), in the manner set forth below by paying cash at a price per share
equal to the product of the Exchange Ratio and the closing price of one share
of Parent Common Stock on the last completed Nasdaq trading day prior to
execution of this Agreement (the "Exercise Price").

  2. Exercise of Option.

    (a) The Option may be exercised by Parent, in whole or in part, at any
  time or from time to time (i) after termination of the Reorganization
  Agreement pursuant to Section 7.1(g) or 7.1(h) thereof or (ii) upon the
  occurrence of any event causing the Termination Fee to become payable
  pursuant to Section 7.3(b)(ii) of the Reorganization Agreement (any of the
  events described in clause (i) and (ii) of this sentence being referred to
  herein as an "Exercise Event"). In the event Parent wishes to exercise the
  Option, Parent will deliver to the Company a written notice (each an
  "Exercise Notice") specifying the total number of Option Shares it wishes
  to acquire. Each closing of a purchase of Option Shares (a "Closing") will
  occur on a date and at a time prior to the termination of the Option
  designated by Parent in an Exercise Notice delivered at least two (2)
  business days prior to the date of such Closing, which Closing will be held
  at the principal offices of the Company.

    (b) The Option will terminate upon the earliest of (i) the Effective
  Time, (ii) twelve (12) months following the date on which the
  Reorganization Agreement is terminated pursuant to Section 7.1(b) or
  7.1(d)(i) thereof, if no event causing the Termination Fee to become
  payable pursuant to Section 7.3(b)(ii) of the Reorganization Agreement has
  occurred, (iii) twelve (12) months following the date on which the
  Reorganization Agreement is terminated pursuant to Section 7.1(g) or 7.1(h)
  thereof, (iv) in the event the Reorganization Agreement has been terminated
  pursuant to Section 7.1(b) or 7.1(d)(i) thereof and the Termination Fee
  became payable pursuant to Section 7.3(b)(ii) thereof, twelve (12) months
  after payment of the Termination Fee; and (v) the date on which the
  Reorganization Agreement is terminated other than pursuant to Sections
  7.1(b), 7.1(d)(i), 7.1(g) or 7.1(h); provided, however, that if the Option
  cannot be exercised by reason of any applicable government order or because
  the waiting period related to the issuance of the Option Shares under the
  HSR Act will not

                                     A-B-1
<PAGE>

  have expired or been terminated, then the Option will not terminate until
  the tenth business day after such impediment to exercise will have been
  removed or will have become final and not subject to appeal.

  3. Conditions to Closing. The obligation of Company to issue Option Shares to
Parent hereunder is subject to the conditions that (A) any waiting period under
the HSR Act applicable to the issuance of the Option Shares hereunder will have
expired or been terminated; (B) all material consents, approvals, orders or
authorizations of, or registrations, declarations or filings with, any Federal,
state or local administrative agency or commission or other Federal state or
local governmental authority or instrumentality, if any, required in connection
with the issuance of the Option Shares hereunder will have been obtained or
made, as the case may be; and (C) no preliminary or permanent injunction or
other order by any court of competent jurisdiction prohibiting or otherwise
restraining such issuance will be in effect. It is understood and agreed that
at any time during which the Option is exercisable, the parties will use their
respective best efforts to satisfy all conditions to Closing, so that a Closing
may take place as promptly as practicable.

  4. Closing. At any Closing, (A) the Company will deliver to Parent a single
certificate in definitive form representing the number of Company Shares
designated by Parent in its Exercise Notice, such certificate to be registered
in the name of Parent and to bear the legend set forth in Section 12 hereof,
against delivery of (B) payment by Parent to the Company of the aggregate
purchase price for the Company Shares so designated and being purchased by
delivery of a certified check or bank check.

  5. Representations and Warranties of the Company. Company represents and
warrants to Parent that (A) Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and has
the corporate power and authority to enter into this Agreement and to carry out
its obligations hereunder; (B) the execution and delivery of this Agreement by
the Company and consummation by the Company of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of the Company and no other corporate proceedings on the part of the Company
are necessary to authorize this Agreement or any of the transactions
contemplated hereby; (C) this Agreement has been duly executed and delivered by
the Company and constitutes a legal, valid and binding obligation of the
Company and, assuming this Agreement constitutes a legal, valid and binding
obligation of Parent, is enforceable against the Company in accordance with its
terms; (D) except for any filings required under the HSR Act, the Company has
taken all necessary corporate and other action to authorize and reserve for
issuance and to permit it to issue upon exercise of the Option, and at all
times from the date hereof until the termination of the Option will have
reserved for issuance, a sufficient number of unissued Company Shares for
Parent to exercise the Option in full and will take all necessary corporate or
other action to authorize and reserve for issuance all additional Company
Shares or other securities which may be issuable pursuant to Section 11(a) upon
exercise of the Option, all of which, upon their issuance and delivery in
accordance with the terms of this Agreement, will be validly issued, fully paid
and nonassessable; (E) upon delivery of the Company Shares and any other

by the Company will not, (i) conflict with or violate the Certificate of
Incorporation or Bylaws or equivalent organizational documents of the Company
or any of its subsidiaries, (ii) conflict with or violate any law, rule,
regulation, order, judgment or decree applicable to the Company or any of its
subsidiaries or by which its or any of their respective properties is bound or
affected or (iii) result in any breach of or constitute a default (or an event
that with notice or lapse of time or both would become a default) under, or
impair the Company's or any of its subsidiaries' rights or alter the rights or
obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or encumbrance on any of the properties or assets of the

mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which the Company or any of its subsidiaries
is a party or by which the Company or any of its subsidiaries or its or any of
their respective properties are

                                     A-B-2
<PAGE>

bound or affected; and (G) the execution and delivery of this Agreement by the
Company does not, and the performance of this Agreement by the Company will
not, require any consent, approval, authorization or permit of, or filing with,
or notification to, any Governmental Entity except pursuant to the HSR Act.

  6. Representations and Warranties of Parent. Parent represents and warrants

  7.  Certain Rights.

    (a) Parent Put. At the request of and upon notice by Parent (the "Put
  Notice"), at any time during the period during which the Option is
  exercisable pursuant to Section 2 (the "Purchase Period"), the Company (or
  any successor entity thereof) will purchase from Parent all or any portion
  of the Option, to the extent not previously exercised, at the price set
  forth in subparagraph (i) below, and all or any portion of the Option
  Shares, if any, acquired by Parent pursuant thereto, at the price set forth
  in subparagraph (ii) below:

      (i) The difference between the "Market/Tender Offer Price" for the
    Company Shares as of the date Parent gives notice of its intent to
    exercise its rights under this Section 7(a) (defined as the higher of
    (A) the highest price per share offered as of such date pursuant to any
    Acquisition Proposal which was made prior to such date and (B) the
    highest closing sale price of Company Shares then on the Nasdaq
    National Market during the twenty (20) trading days ending on the
    trading day immediately preceding such date) and the Exercise Price,
    multiplied by the number of Company Shares purchasable pursuant to the
    Option, but only if the Market/Tender Offer Price is greater than the
    Exercise Price. For purposes of determining the highest price offered
    pursuant to any Acquisition Proposal which involves consideration other
    than cash, the value of such consideration will be equal to the higher
    of (x) if securities of the same class of the proponent as such
    consideration are traded on any national securities exchange or by any
    registered securities association, a value based on the closing sale
    price or asked price for such securities on their principal trading
    market on such date and (y) the value ascribed to such consideration by
    the proponent of such Acquisition Proposal, or if no such value is
    ascribed, a value determined in good faith by the Board of Directors of
    the Company.

                                     A-B-3
<PAGE>

    (ii) The Exercise Price paid by Parent for Company Shares acquired
    pursuant to the Option plus the difference between the Market/Tender
    Offer Price and such Exercise Price (but only if the Market/Tender
    Offer Price is greater than the Exercise Price) multiplied by the
    number of Company Shares so purchased.

  8. Payment and Redelivery of Option or Shares. In the event Parent exercises
its rights under Section 7(a) by delivery of a Put Notice, the Company will,
within five (5) business days after Parent delivers such notice, pay the
required amount to Parent in immediately available funds and Parent will
surrender to the Company all or such portion of the Option with respect to
which the Put Notice relates and the certificates evidencing the Company Shares
purchased by Parent pursuant to such Put Notice.

  9. Registration Rights.

    (a) Following the termination of the Reorganization Agreement, Parent
  (sometimes referred to herein as the "Holder") may by written notice (a
  "Registration Notice") to the Company (the "Registrant") request the
  Registrant to register under the Securities Act all or any part of the
  shares acquired by the Holder pursuant to this Agreement (such shares
  requested to be registered, the "Registrable Securities") in order to
  permit the sale or other disposition of any or all shares of the
  Registrable Securities that have been acquired by or are issuable to Holder
  upon exercise of the Option in accordance with the intended method of sale
  or other disposition stated by Holder, including a "shelf" registration
  statement under Rule 415 under the Securities Act or any successor
  provision. Holder agrees to cause, and to cause any underwriters of any
  sale or other disposition to cause, any sale or other disposition pursuant
  to such registration statement to be effected on a widely distributed basis
  so that upon consummation thereof no purchaser or transferee will own
  beneficially more than 5.0% of the then-outstanding voting power of
  Registrant. Upon a request for registration, the Registrant will have the
  option exercisable by written notice delivered to the Holder within ten
  (10) business days after the receipt of the Registration Notice,
  irrevocably to agree to purchase all or any part of the Registrable
  Securities for cash at a price (the "Option Price") equal to the product of
  (i) the number of Registrable Securities so purchased and (ii) the per
  share average of the closing sale prices of the Registrant's Common Stock
  on the Nasdaq National Market for the ten (10) trading days immediately
  preceding the date of the Registration Notice. Any such purchase of
  Registrable Securities by the Registrant hereunder will take place at a
  closing to be held at the principle executive offices of the Registrant or
  its counsel at any reasonable date and time designated by the Registrant in
  such notice within ten business days after delivery of such notice. The
  payment for the shares to be purchased will be made by delivery at the time
  of such closing of the Option Price in immediately available funds.

    (b) If the Registrant does not elect to exercise its option to purchase
  pursuant to Section 7(a) with respect to all Registrable Securities, the
  Registrant will use all reasonable efforts to effect, as promptly as
  practicable, the registration under the Securities Act of the unpurchased
  Registrable Securities requested to be registered in the Registration
  Notice and to keep such registration statement effective for such period
  not in excess of 120 calendar days from the day such registration statement
  first becomes effective as may be reasonably necessary to effect such sale
  or other disposition; provided, however, that the Holder will not be
  entitled to more than an aggregate of two (2) effective registration
  statements hereunder. The obligations of Registrant hereunder to file a
  registration statement and to maintain its effectiveness may be suspended
  for up to 120 calendar days in the aggregate if the Board of Directors of
  Registrant shall have determined that the filing of such registration
  statement or the maintenance of its effectiveness would require premature
  disclosure of material nonpublic information that would materially and
  adversely affect Registrant or otherwise interfere with or adversely affect
  any pending or proposed offering of securities of Registrant or any other
  material transaction involving Registrant. If consummation of the sale of
  any Registrable Securities pursuant to a registration hereunder does not
  occur within 120 days after the filing with the SEC of the initial
  registration statement therefor, the provisions of this Section 9 will
  again be applicable to any proposed

                                     A-B-4
<PAGE>

  registration. The Registrant will use all reasonable efforts to cause any
  Registrable Securities registered pursuant to this Section 9 to be
  qualified for sale under the securities or blue sky laws of such
  jurisdictions as the Holder may reasonably request and will continue such
  registration or qualification in effect in such jurisdictions; provided,
  however, that the Registrant will not be required to qualify to do business
  in, or consent to general service of process in, any jurisdiction by reason
  of this provision. If Registrant effects a registration under the
  Securities Act of Company Common Stock for its own account or for any other
  stockholders of Registrant (other than on Form S-4 or Form S-8, or any
  successor form), it will allow Holder the right to participate in such
  registration by selling its Registrable Securities, and such participation
  will not affect the obligation of Registrant to effect demand registration
  statements for Holder under this Section 9; provided that, if the managing
  underwriters of such offering advise Registrant in writing that in their
  opinion the number of shares of Company Common Stock requested to be
  included in such registration exceeds the number which can be sold in such
  offering, Registrant will include the shares requested to be included
  therein by Holder pro rata with the shares intended to be included therein
  by Registrant.

    (c) The registration rights set forth in this Section 9 are subject to
  the condition that the Holder will provide the Registrant with such
  information with respect to the Holder's Registrable Securities, the plan
  for distribution thereof, and such other information with respect to the
  Holder as, in the reasonable judgment of counsel for the Registrant, is
  necessary to enable the Registrant to include in a registration statement
  all facts required to be disclosed with respect to a registration
  thereunder.

    (d) A registration effected under this Section 9 will be effected at the
  Registrant's expense, except for underwriting discounts and commissions and
  the fees and expenses of counsel to the Holder, and the Registrant will
  provide to the underwriters such documentation (including certificates,
  opinions of counsel and "comfort" letters from auditors) as are customary
  in connection with underwritten public offerings and as such underwriters
  may reasonably require. In connection with any registration, the Holder and
  the Registrant agree to enter into an underwriting agreement reasonably
  acceptable to each such party, in form and substance customary for
  transactions of this type with the underwriters participating in such
  offering.

    (e) Indemnification.

      (i) The Registrant will indemnify the Holder, each of its directors
    and officers and each person who controls the Holder within the meaning
    of Section 15 of the Securities Act, and each underwriter of the
    Registrant's securities, with respect to any registration,
    qualification or compliance which has been effected pursuant to this
    Agreement, against all expenses, claims, losses, damages or liabilities
    (or actions in respect thereof), including any of the foregoing
    incurred in settlement of any litigation, commenced or threatened,
    arising out of or based on any untrue statement (or alleged untrue
    statement) of a material fact contained in any registration statement,
    prospectus, offering circular or other document, or any amendment or
    supplement thereto, incident to any such registration, qualification or
    compliance, or based on any omission (or alleged omission) to state
    therein a material fact required to be stated therein or necessary to
    make the statements therein, in light of the circumstances in which
    they were made, not misleading, or any violation by the Registrant of
    any rule or regulation promulgated under the Securities Act applicable
    to the Registrant in connection with any such registration,
    qualification or compliance, and the Registrant will reimburse the
    Holder and, each of its directors and officers and each person who
    controls the Holder within the meaning of Section 15 of the Securities
    Act, and each underwriter for any legal and any other expenses
    reasonably incurred in connection with investigating, preparing or
    defending any such claim, loss, damage, liability or action; provided,
    that the Registrant will not be liable in any such case to the extent
    that any such claim, loss, damage, liability or expense arises out of
    or is based on any untrue statement or omission or alleged untrue
    statement or omission, made in reliance upon and in conformity with
    written

                                     A-B-5
<PAGE>

    information furnished to the Registrant by such Holder or director or
    officer or controlling person or underwriter seeking indemnification.

      (ii) The Holder will indemnify the Registrant, each of its directors
    and officers and each underwriter of the Registrant's securities
    covered by such registration statement and each person who controls the
    Registrant within the meaning of Section 15 of the Securities Act,
    against all expenses, claims, losses, damages and liabilities (or
    actions in respect thereof), including any of the foregoing incurred in
    settlement of any litigation, commenced or threatened, arising out of
    or based on any untrue statement (or alleged untrue statement) of a
    material fact contained in any such registration statement, prospectus,
    offering circular or other document, or any 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
    any violation by the Holder of any rule or regulation promulgated under
    the Securities Act applicable to the Holder in connection with any such
    registration, qualification or compliance, and will reimburse the
    Registrant, such directors, officers or control persons or underwriters
    for any legal or any other expenses reasonably incurred in connection
    with investigating, preparing or defending any such claim, loss,
    damage, liability or action, in each case to the extent, but only to
    the extent, that such untrue statement (or alleged untrue statement) or
    omission (or alleged omission) is made in such registration statement,
    prospectus, offering circular or other document in reliance upon and in
    conformity with written information furnished to the Registrant by the
    Holder for use therein; provided, that in no event will any indemnity
    under this Section 9(e) exceed the net proceeds of the offering
    received by the Holder.

      (iii) Each party entitled to indemnification under this Section 9(e)
    (the "Indemnified Party") will give notice to the party required to
    provide indemnification (the "Indemnifying Party") promptly after such
    Indemnified Party has actual knowledge of any claim as to which
    indemnity may be sought, and will permit the Indemnifying Party to
    assume the defense of any such claim or any litigation resulting
    therefrom, provided, that counsel for the Indemnifying Party, who will
    conduct the defense of such claim or litigation, will be approved by
    the Indemnified Party (whose approval will not unreasonably be
    withheld), and the Indemnified Party may participate in such defense at
    such party's expense; provided, however, that the Indemnifying Party
    will pay such expense if representation of the Indemnified Party by
    counsel retained by the Indemnifying Party would be inappropriate due
    to actual or potential differing interests between the Indemnified
    Party and any other party represented by such counsel in such
    proceeding, and provided further, however, that the failure of any
    Indemnified Party to give notice as provided herein will not relieve
    the Indemnifying Party of its obligations under this Section 9(e)
    unless the failure to give such notice is materially prejudicial to an
    Indemnifying Party's ability to defend such action. No Indemnifying
    Party, in the defense of any such claim or litigation will, except with
    the consent of each Indemnified Party, consent to entry of any judgment
    or enter into any settlement which does not include as an unconditional
    term thereof the giving by the claimant or plaintiff to such
    Indemnified Party of a release from all liability in respect to such
    claim or litigation. No Indemnifying Party will be required to
    indemnify any Indemnified Party with respect to any settlement entered
    into without such Indemnifying Party's prior consent (which will not be
    unreasonably withheld).

  10. Profit Limitation.

    (a) Notwithstanding any other provision in this Agreement or the
  Reorganization Agreement, in no event shall Parent's Total Profit (as
  defined below) exceed $120,000,000 (the "Maximum Profit") and, if Parent's
  Total Profit otherwise would exceed the Maximum Profit, Parent, at its sole
  discretion shall either (i) reduce the number of Option Shares subject to
  the Option, (ii) deliver to the Company for cancellation Option Shares (or
  other securities into which such Option Shares are converted or exchanged)
  previously purchased by Parent, (iii) pay cash to the Company, or (iv) any
  combination of

                                     A-B-6
<PAGE>

  the foregoing, so that Parent's actual realized Total Profit shall not
  exceed the Maximum Profit after taking into account the foregoing actions;
  provided, however, that to the extent the payment by the Company of cash to
  Parent in satisfaction of the Termination Fee pursuant to Section 7.3 of
  the Reorganization Agreement would cause Parent's Total Profit to exceed
  the Maximum Profit (after Parent has had an opportunity to reduce Parent's
  Total Profit pursuant to this Section 10(a)), then the Company need not pay
  such cash portion of the Termination Fee.

    (b) For purposes of this Agreement, "Total Profit" shall mean: (i) the
  aggregate amount of (A) any excess of (x) the net cash amounts or fair
  market value of any property received by Parent pursuant to a sale of
  Option Shares (or securities into which such shares are converted or
  exchanged) over (y) Parent's aggregate purchase price for such Option
  Shares (or other securities), plus (B) any amounts received by Parent on
  the repurchase of the Option by the Company pursuant to Section 7, plus
  (C) any Termination Fee paid by the Company and received by Parent pursuant
  to the Reorganization Agreement, minus (ii) the amounts of any cash
  previously paid by Parent to the Company pursuant to this Section 10 plus
  the value of the Option Shares (or other securities) previously delivered
  to the Company for cancellation pursuant to this Section 10.

    (c) For purposes of Section 10(a) and clause (i) of Section 10(b), the
  value of any Option Shares delivered by Parent to the Company shall be the
  Market/Tender Offer Price of such Options Shares.

  11. Adjustment Upon Changes in Capitalization.

    (a) In the event of any change in the Company Shares by reason of stock
  dividends, stock splits, reverse stock splits, mergers (other than the
  Merger), recapitalizations, combinations, exchanges of shares and the like,
  the type and number of shares or securities subject to the Option, and the
  Exercise Price will be adjusted appropriately, and proper provision will be
  made in the agreements governing such transaction so that Parent will
  receive, upon exercise of the Option, the number and class of shares or
  other securities or property that Parent would have received in respect of
  the Company Shares if the Option had been exercised immediately prior to
  such event or the record date therefor, as applicable.

    (b) Without limiting the parties' relative rights and obligations under
  the Reorganization Agreement if the number of outstanding shares of Company
  Common Stock increases after the date of this Agreement (other than
  pursuant to an event described in Section 11(a)), the number of shares of
  Company Common Stock subject to the Option (including those Option Shares
  which may have already been exercised) will be adjusted so that it equals
  19.9% of the number of shares of Company Common Stock then issued and
  outstanding, without giving effect to any Option Shares.

  12. Restrictive Legends. Each certificate representing Option Shares issued
to Parent hereunder will include a legend in substantially the following form:

    THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
    UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR
    SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
    AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS
    ON TRANSFER AS SET FORTH IN THE STOCK OPTION AGREEMENT DATED AS OF JULY
    26, 2000, A COPY OF WHICH MAY BE OBTAINED FROM THE ISSUER.

  It is understood and agreed that (i) the reference to restrictions arising
under the Securities Act in the above legend will be removed by delivery of
substitute certificate(s) without such reference if such Option Shares have
been registered pursuant to the Securities Act, such Option Shares have been
sold in reliance on and in accordance with Rule 144 under the Securities Act or
Holder has delivered to Registrant a copy of a letter from the staff of the
SEC, or an opinion of counsel in form and substance reasonably satisfactory to
Registrant and its counsel, to the effect that such legend is not required for
purposes of the Securities Act

                                     A-B-7
<PAGE>

and (ii) the reference to restrictions pursuant to this Agreement in the above
legend will be removed by delivery of substitute certificate(s) without such
reference if the Option Shares evidenced by certificate(s) containing such
reference have been sold or transferred in compliance with the provisions of
this Agreement under circumstances that do not require the retention of such
reference.

  13. Listing and HSR Filing. The Company, upon the request of Parent, will
promptly file an application to list the Company Shares to be acquired upon
exercise of the Option for quotation on the Nasdaq National Market and will use
its best efforts to obtain approval of such listing as soon as practicable.
Promptly after the date hereof, each of the parties hereto will promptly file
with the Federal Trade Commission and the Antitrust Division of the United
States Department of Justice all required premerger notification and report
forms and other documents and exhibits required to be filed under the HSR Act
to permit the acquisition of the Company Shares subject to the Option at the
earliest possible date.

  14. Binding Effect. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors and permitted
assigns. Nothing contained in this Agreement, express or implied, is intended
to confer upon any person other than the parties hereto and their respective
successors and permitted assigns any rights or remedies of any nature
whatsoever by reason of this Agreement. Any shares sold by a party in
compliance with the provisions of Section 9 will, upon consummation of such
sale, be free of the restrictions imposed with respect to such shares by this
Agreement and any transferee of such shares will not be entitled to the rights
of such party. Certificates representing shares sold in a registered public
offering pursuant to Section 9 will not be required to bear the legend set
forth in Section 12.

  15. Specific Performance. The parties hereto recognize and agree that if for
any reason any of the provisions of this Agreement are not performed in
accordance with their specific terms or are otherwise breached, immediate and
irreparable harm or injury would be caused for which money damages would not be
an adequate remedy. Accordingly, each party hereto agrees that in addition to
other remedies the other party hereto will be entitled to an injunction
restraining any violation or threatened violation of the provisions of this
Agreement or the right to enforce any of the covenants or agreements set forth
herein by specific performance. In the event that any action will be brought in
equity to enforce the provisions of the Agreement, neither party hereto will
allege, and each party hereto hereby waives the defense, that there is an
adequate remedy at law.

  16. Entire Agreement. This Agreement and the Reorganization Agreement
(including the appendices thereto) constitute the entire agreement between the
parties hereto with respect to the subject matter hereof and supersede all
other prior agreements and understandings, both written and oral, between the
parties hereto with respect to the subject matter hereof.

  17. Further Assurances. Each party hereto will execute and deliver all such
further documents and instruments and take all such further action as may be
necessary in order to consummate the transactions contemplated hereby.

  18. Validity. The invalidity or unenforceability of any provision of this
Agreement will not affect the validity or enforceability of the other
provisions of this Agreement, which will remain in full force and effect. In
the event any Governmental Entity of competent jurisdiction holds any provision
of this Agreement to be null, void or unenforceable, the parties hereto will
negotiate in good faith and will execute and deliver an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the extent
permitted by law, the intent of the parties hereto with respect to such
provision.

  19. Notices. All notices and other communications hereunder will be in
writing and will be deemed given if delivered personally or by commercial
delivery service, or sent via telecopy (receipt confirmed) to

                          COMPANY AFFILIATE AGREEMENT

  THIS COMPANY AFFILIATE AGREEMENT (this "Agreement") is made and entered into
as of July 26, 2000, between InfoSpace, Inc., a Delaware corporation
("Parent"), and the undersigned stockholder of Go2Net, Inc., a Delaware
corporation ("Company"), who may be deemed an affiliate ("Affiliate") of
Company. Capitalized terms used but not otherwise defined herein shall have
the meanings ascribed to them in the Reorganization Agreement (as defined
below).

                                   RECITALS

  A. The Company, Merger Sub (as defined below) and Parent have entered into
an Agreement and Plan of Reorganization (the "Reorganization Agreement") which
provides for the merger (the "Merger") of Giants Acquisition Corp., a wholly-
owned subsidiary of Parent ("Merger Sub"), with and into the Company. Pursuant
to the Merger, all issued and outstanding capital stock of the Company (the
"Company Capital Stock") as of the Effective Time (as defined in the
Reorganization Agreement) will be converted into Common Stock of Parent as set
forth in the Reorganization Agreement;

  B. The execution and delivery of this Agreement by Affiliate is a material
inducement to Parent to enter into the Reorganization Agreement; and

  C. Affiliate has been advised that Affiliate may be deemed to be an
"affiliate" of Parent after the Merger as the term "affiliate" is used (i) for
purposes of Rule 144 of the Rules and Regulations (the "Rules and
Regulations") of the Securities and Exchange Commission (the "Commission") and
(ii) in Accounting Series Releases 130 and 135, as amended, although nothing
contained herein shall be construed as an admission by Affiliate that
Affiliate is in fact an "affiliate" of Parent.

  NOW, THEREFORE, intending to be legally bound, the parties hereto agree as
follows:

  1. Acknowledgments by Affiliate. Affiliate acknowledges and understands that
the representations, warranties and covenants by Affiliate set forth herein
will be relied upon by Parent, the Company and their respective affiliates,
counsel and accounting firms for purposes of determining Parent's eligibility
to account for the Merger as a "pooling of interests." Affiliate has carefully
read this Agreement and the Reorganization Agreement and has had the
opportunity to discuss the requirements of this Agreement with Affiliate's
professional advisors, who Affiliate believes are qualified to advise
Affiliate with regard to such matters.

  2. Beneficial Ownership of Company Capital Stock. The Affiliate is the sole
beneficial owner of the number of shares of Company Capital Stock set forth
next to its name on the signature page hereto (the "Shares"). There are no
options, warrants, calls, rights, commitments or agreements of any character,
written or oral, to which the Affiliate is party or by which it is bound
obligating the Affiliate to issue, deliver, sell or redeem prior to the end of
the Restricted Period (as defined in Section 3 below), or cause to be issued,
delivered, sold or redeemed prior to the end of the Restricted Period, any
Shares or obligating the Affiliate to grant or enter into any such option,
warrant, call, right, commitment or agreement prior to the end of the
Restricted Period. The Affiliate has the sole right to transfer such Shares.
The Shares constitute all shares of Company Capital Stock owned, beneficially
or of record, by the Affiliate. The Affiliate has not engaged in any sale or
other transfer of the Shares in contemplation of the Merger. All shares of
Company Capital Stock and common stock of Parent ("Parent Common Stock")
acquired by Affiliate subsequent to the date hereof (including shares of
Parent Common Stock acquired in the Merger) shall be subject to the provisions
of this Agreement, to the extent such provisions are then still applicable, as
if held by Affiliate as of the date hereof.

  3. Covenants Related to Pooling of Interests. In accordance with Staff
Accounting Bulletin No. 65, during the period from the date 30 days prior to
the Effective Time until the day Parent publicly announces

                                    A-C-1-1
<PAGE>

financial results covering at least 30 days of combined operations of Parent
and the Company (the "Restricted Period"), Affiliate shall not sell, exchange,
transfer, pledge, distribute, make any gift or otherwise dispose of or grant
any option, establish any "short" or put-equivalent position with respect to or
enter into any similar transaction (through derivatives or otherwise) intended
or having the effect, directly or indirectly, to reduce Affiliate's risk
relative to any shares of Parent Common Stock or Company Capital Stock
(including the Shares). Parent may, at its discretion, place a stock transfer
notice consistent with the foregoing, with respect to Affiliate's shares of
Parent Common Stock provided that such notice shall be countermanded as soon as
practicable upon expiration of the necessity therefor.

  4. Compliance with Rule 145 and the Securities Act.

    (a) Affiliate has been advised that (i) the issuance of shares of Parent
  Common Stock in connection with the Merger is expected to be effected
  pursuant to a registration statement on Form S-4 promulgated under the
  Securities Act of 1933, as amended (the "Securities Act"), and the resale
  of such shares shall be subject to restrictions set forth in Rule 145 under
  the Securities Act, and (ii) Affiliate may be deemed to be an affiliate of
  the Company. Affiliate accordingly agrees not to sell, transfer or
  otherwise dispose of any Parent Common Stock issued to Affiliate in the
  Merger unless (i) such sale, transfer or other disposition is made in
  conformity with the requirements of Rule 145(d) promulgated under the
  Securities Act, (ii) such sale, transfer or other disposition is made
  pursuant to an effective registration statement under the Securities Act or
  an appropriate exemption from registration, (iii) Affiliate delivers to
  Parent a written opinion of counsel, reasonably acceptable to Parent in
  form and substance, that such sale, transfer or other disposition is
  otherwise exempt from registration under the Securities Act or (iv) an
  authorized representative of the Commission shall have rendered written
  advice to Affiliate to the effect that the Commission would take no action,
  or that the staff of the Commission would not recommend that the Commission
  take any action, with respect to the proposed disposition if consummated
  (the "No Action Correspondence").

    (b) Parent shall give stop transfer instructions to its transfer agent
  with respect to any Parent Common Stock received by Affiliate in the Merger
  and there shall be placed on the certificates representing such Common
  Stock, or any substitutions therefor issued prior to the end of the
  Restricted Period, a legend stating in substance:

      "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
    TRANSACTION TO WHICH RULE 145 APPLIES AND MAY ONLY BE TRANSFERRED (A)
    IN CONFORMITY WITH RULE 145(d), OR (B) PURSUANT TO AN EFFECTIVE
    REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
    (C) IN ACCORDANCE WITH A WRITTEN OPINION OF COUNSEL, REASONABLY
    ACCEPTABLE TO THE ISSUER IN FORM AND SUBSTANCE, THAT SUCH TRANSFER IS
    EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED."

  The legend set forth above shall be removed (by delivery of a substitute
certificate without such legend) and Parent shall instruct its transfer agent
to remove such legend, if Affiliate delivers to Parent (i) satisfactory written
evidence that the shares have been sold in compliance with Rule 145 (in which
case, the substitute certificate shall be issued in the name of the
transferee), (ii) the No Action Correspondence, (iii) an opinion of counsel, in
form and substance reasonably satisfactory to Parent, to the effect that public
sale of the shares by the holder thereof is no longer subject to Rule 145, or
(iv) a written request for removal of such legend after the first anniversary
of the Effective Time.

  5. Termination.

    (a) This Agreement shall be terminated and shall be of no further force
  and effect in the event of the termination of the Reorganization Agreement
  pursuant to Article VII of the Reorganization Agreement.

                                    A-C-1-2
<PAGE>

    (b) If at any time prior to the effective time, Parent determines in its
  sole discretion that the Merger may not be accounted for as a "pooling of
  interests," or, if at any time after the Effective Time, the Merger is not
  be accounted for as a "pooling of interests," then the restrictions set
  forth in Section 3 of this Agreement shall terminate and shall be of no
  further force and effect.

  6. Miscellaneous.

    (a) Waiver; Severability. No waiver by any party hereto of any condition
  or of any breach of any provision of this Agreement shall be effective
  unless in writing and signed by each party hereto. In the event that any
  provision of this Agreement, or the application of any such provision to
  any person, entity or set of circumstances, shall be determined to be
  invalid, unlawful, void or unenforceable to any extent, the remainder of
  this Agreement, and the application of such provision to persons, entities
  or circumstances other than those as to which it is determined to be
  invalid, unlawful, void or unenforceable, shall not be impaired or
  otherwise affected and shall continue to be valid and enforceable to the
  fullest extent permitted by law.

    (b) Binding Effect and Assignment. This Agreement and all of the
  provisions hereof shall be binding upon and inure to the benefit of the
  parties hereto and their respective successors and permitted assigns, but,
  except as otherwise specifically provided herein, neither this Agreement
  nor any of the rights, interests or obligations of the parties hereto may
  be assigned by either of the parties without prior written consent of the
  other party hereto.

    (c) Amendments and Modification. This Agreement may not be modified,
  amended, altered or supplemented except upon the execution and delivery of
  a written agreement executed by the parties hereto.

    (d) Injunctive Relief. Each of the parties acknowledge that (i) the
  covenants and the restrictions contained in this Agreement are necessary,
  fundamental, and required for the protection of Parent and the Company and
  to preserve for Parent the benefits of the Merger; (ii) such covenants
  relate to matters which are of a special, unique, and extraordinary
  character that gives each of such covenants a special, unique, and
  extraordinary value; and (iii) a breach of any such covenants or any other
  provision of this Agreement shall result in irreparable harm and damages to
  Parent and the Company which cannot be adequately compensated by a monetary
  award. Accordingly, it is expressly agreed that in addition to all other
  remedies available at law or in equity, Parent and the Company shall be
  entitled to the immediate remedy of a temporary restraining order,
  preliminary injunction, or such other form of injunctive or equitable
  relief as may be used by any court of competent jurisdiction to restrain or
  enjoin any of the parties hereto from breaching any such covenant or
  provision or to specifically enforce the provisions hereof.

    (e) Governing Law. This Agreement shall be governed by and construed,
  interpreted and enforced in accordance with the internal laws of the State
  of Delaware without giving effect to any choice or conflict of law
  provision or rule (whether of the State of Delaware or any other
  jurisdiction) that would cause the application of the laws of any
  jurisdiction other than the State of Delaware.

    (f) Entire Agreement. This Agreement sets forth the entire understanding
  of Affiliate and Parent relating to the subject matter hereof and
  supersedes all prior agreements and understandings between Affiliate and
  Parent relating to the subject matter hereof.

    (g) Attorneys' Fees. In the event of any legal actions or proceeding to
  enforce or interpret the provisions hereof, the prevailing party shall be
  entitled to reasonable attorneys' fees, whether or not the proceeding
  results in a final judgment.

    (h) Further Assurances. Affiliate shall execute and/or cause to be
  delivered to Parent such instruments and other documents and shall take
  such other actions as Parent may reasonably request to effectuate the
  intent and purposes of this Agreement.

    (i) Third Party Reliance. Counsel to and independent auditors for Parent
  and the Company shall be entitled to rely upon this Affiliate Agreement.

    (j) Survival. The representations, warranties, covenants and other
  provisions contained in this Agreement shall survive the Merger.

    (k) Notices. All notices and other communications pursuant to this
  Agreement shall be in writing and deemed to be sufficient if contained in a
  written instrument and shall be deemed given if delivered personally,
  telecopied, sent by nationally-recognized overnight courier or mailed by

Board of Directors
Infospace, Inc.
601-108th Avenue NE
Suite 1200
Bellevue, WA 98004

Members of the Board:

  We understand that Go2Net, Inc. ("Go2Net" or the "Company"), Infospace, Inc.
("Infospace") and Giants Acquisition Corp., a wholly-owned subsidiary of
Infospace ("Merger Sub"), propose to enter into an Agreement and Plan of
Reorganization, substantially in the form of the draft dated July 26, 2000
(the "Merger Agreement"), which provides, among other things, for the merger
(the "Merger") of Merger Sub with and into the Company. Pursuant to the
Merger, the Company will become a wholly-owned subsidiary of Infospace and
each issued and outstanding share of common stock, par value $0.01 per share,
of Go2Net ("Go2Net Common Stock"), other than shares held in treasury or held
by Infospace, Merger Sub or any direct or indirect wholly-owned subsidiary of
the Company or Infospace, together with any associated rights to purchase
Go2Net Common Stock will be converted into the right to receive 1.820 shares
(the "Exchange Ratio") of common stock, par value $0.0001 per share, of
Infospace ("Infospace Common Stock"). The terms and conditions of the Merger
are more fully set forth in the Merger Agreement.

  You have asked for our opinion as to whether the Exchange Ratio pursuant to
the Merger Agreement is fair from a financial point of view to Infospace.

  For purposes of the opinion set forth herein, we have:

    (i) reviewed certain publicly available financial statements and other
  information of the Company and Infospace;

    (ii) reviewed certain internal financial statements and other financial
  and operating data concerning the Company prepared by the management of the
  Company;

    (iii) reviewed certain financial projections prepared by the management
  of the Company;

    (iv) reviewed certain internal financial statements and other financial
  and operating data concerning Infospace prepared by the management of
  Infospace;

    (v) reviewed certain financial projections prepared by the management of
  Infospace;

    (vi) reviewed the past and current operations and financial condition and
  the prospects of the Company and Infospace, including information relating
  to certain strategic, financial and operational benefits anticipated from
  the Merger, with senior executives of the Company and Infospace,
  respectively;

    (vii) reviewed the pro forma impact of the Merger on Infospace's
  financial performance, including revenue per share and earnings per share;

    (viii) reviewed the reported prices and trading activity for Go2Net
  Common Stock and Infospace Common Stock;

    (ix) compared the financial performance of the Company and Infospace and
  the prices and trading activity of Go2Net Common Stock and Infospace Common
  Stock with that of certain other publicly-traded companies comparable with
  the Company and Infospace, respectively, and their securities;

    (x) reviewed the financial terms, to the extent publicly available, of
  certain comparable acquisition transactions;

                                      B-1
<PAGE>

    (xi) participated in discussions and negotiations among representatives
  of the Company and Infospace and their financial and legal advisors;

    (xii) reviewed a draft of the Merger Agreement dated July 26, 2000, and
  certain related documents; and

    (xiii) performed such other analyses and considered such other factors as
  we have deemed appropriate.

  We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from the Merger, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance of the Company and Infospace, respectively. In
addition, we have assumed that the Merger will be consummated in accordance
with the terms set forth in the draft Merger Agreement dated July 26, 2000,
including that the Merger will be treated as a tax-free reorganization and/or
exchange, each pursuant to the Internal Revenue Code of 1986. We have relied
upon, without independent verification, the assessment by the management of the
Company and Infospace of the strategic benefits expected to result from the
transaction. We have also relied upon, without independent verification, the
assessment by the management of the Company and Infospace of the technologies
and products of the Company and Infospace, the timing and risks associated with
the integration of the Company and Infospace and the validity of, and risks
associated with, the Company's and Infospace's existing and future products and
technologies.

  We have not made any independent valuation or appraisal of the assets or
liabilities of the Company or Infospace, nor have we been furnished with any
such appraisals. Our opinion is necessarily based on financial, economic,
market and other conditions as in effect on, and the information made available
to us as of, the date hereof.

  We have acted as financial advisor to the Board of Directors of Infospace in
connection with this transaction and will receive a fee for our services. In
addition, in the ordinary course of our business we may actively trade the
securities of Infospace for our own account and for the accounts of our
customers and, accordingly, may at any time hold a long or short position in
such securities.

  It is understood that this letter is for the information of the Board of
Directors of Infospace and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its entirety
in any filing made by Infospace in respect of the transaction with the
Securities and Exchange Commission. In addition, this opinion does not in any
manner address the prices at which Infospace Common Stock will trade following
the consummation of the Merger.

  Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a
financial point of view to Infospace.

                                          Very truly yours,

                                          Morgan Stanley & Co. Incorporated

[LETTERHEAD OF MERRILL LYNCH & CO.]

                                                                  July 26, 2000

Board of Directors
Go2Net, Inc.
999 Third Avenue, Suite 4700
Seattle, WA 98104

Ladies and Gentlemen:

  Go2Net, Inc. (the "Company") , InfoSpace, Inc. (the "Parent") and Giants
Acquisition Corp., a wholly owned subsidiary of the Parent (the "Merger Sub"),
propose to enter into an agreement (the "Agreement") pursuant to which the
Merger Sub will be merged with and into the Company in a transaction (the
"Merger") in which each outstanding share of the Company's common stock, par
value $0.01 per share (the "Shares"), will be converted into the right to
receive 1.82 shares (the "Exchange Ratio") of the common stock of the Parent,
par value $0.0001 per share (the "Parent Shares"). The Merger is expected to
be considered by the shareholders of the Company at a special meeting of
shareholders to be held on or before November 15, 2000 and consummated on or
shortly after the date of such meeting.

  You have asked us whether, in our opinion, the Exchange Ratio is fair to the
holders of Shares (other than the Parent and its affiliates) from a financial
point of view.

  In arriving at the opinion set forth below, we have, among other things:

    (1) Reviewed certain publicly available business and financial
  information relating to the Company and the Parent that we deemed to be
  relevant;

    (2) Reviewed certain information, including financial forecasts, relating
  to the business, earnings, cash flow, assets and liabilities and prospects
  of the Company and the Parent, furnished to us or discussed with us by the
  Company and the Parent;

    (3) Conducted discussions with members of senior management of the
  Company and the Parent concerning their respective businesses and
  prospects, and potential financial benefits of the Merger;

    (4) Reviewed the historical market prices and trading activity for the
  Shares and the Parent Shares and compared them with that of certain
  publicly traded companies which we deemed to be reasonably similar to the
  Company and the Parent, respectively;

    (5) Compared the results of operations of the Company and the Parent with
  those of certain companies which we deemed to be reasonably similar to the
  Company and the Parent, respectively;

    (6) Compared the proposed financial terms of the transactions
  contemplated by the Agreement with the financial terms of certain other
  mergers and acquisitions which we deemed to be relevant;

    (7) Reviewed the Agreement; and

    (8) Reviewed such other financial studies and analyses and performed such
  other investigations and took into account such other matters as we deemed
  necessary, including our assessment of general economic, market and
  monetary conditions.

  In preparing our opinion, we have relied on the accuracy and completeness of
all information supplied or otherwise made available to us by the Company and
the Parent, and we have not independently verified such information or
undertaken an independent appraisal of the assets of the Company or the
Parent. With respect to the financial forecasts furnished by the Company and
the Parent, we have assumed that they have

                                      C-1
<PAGE>

been reasonably prepared and reflect the best currently available estimates and
judgment of the Company's or the Parent's management as to the expected future
financial performance of the Company or the Parent, as the case may be. For the
purposes of this opinion, we have assumed that neither the Company nor the
Parent is a party to any pending transactions, including external financings,
recapitalizations or material merger discussions other than the 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 letter and
any change in such conditions would require a reevaluation of this opinion. In
rendering this opinion, we have assumed that the Merger will be consummated
substantially on the terms set forth in the Agreement, without any waiver of
any material terms or conditions by any party thereto.

  We have, in the past, provided financial advisory and/or financing services
to the Company and/or its affiliates and the Parent and may continue to do so.
We are acting as financial advisor to the Company in connection with the Merger
and will receive a fee for our services, substantially all of which is
contingent upon the consummation of the Merger. In addition, the Company has
agreed to indemnify us for certain liabilities arising out of our engagement.
In the ordinary course of business, we may actively trade in the securities of
the Company and the Parent for our own account and for the accounts of our
customers and, accordingly, may at any time hold a long or short position in
such securities.

  On the basis of, and subject to the foregoing, we are of the opinion that, as
of the date hereof, the Exchange Ratio is fair to the holders of the Shares
(other than the Parent and its affiliates) from a financial point of view.

                                          Very truly yours,

                                          Merrill Lynch, Pierce, Fenner &
                                                     Smith Incorporated

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

  Section 145 of the Delaware General Corporation Law permits a corporation to
include in its charter documents, and in agreements between the corporation and
its directors and officers, provisions expanding the scope of indemnification
beyond that specifically provided by such section.

  The Registrant's restated certificate of incorporation provides for the
indemnification of directors to the fullest extent permissible under Delaware
law.

  The Registrant's bylaws provides for the indemnification of officers,
directors and third parties acting on behalf of the Registrant if such person
acted in good faith and in a manner reasonably believed to be in and not
opposed to the best interest of the Registrant, and, with respect to any
criminal action or proceeding, the indemnified party had no reason to believe
his or her conduct was unlawful.

  The Registrant has entered into indemnification agreements with its directors
and executive officers and intends to enter into indemnification agreements
with any new directors and executive officers in the future.

  The Registrant has director and officer liability insurance that covers
matters, including matters arising under the Securities Act.

Item 22. Undertakings

  (1) The undersigned Registrant hereby undertakes as follows: that prior to
any public offering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
undersigned Registrant undertakes that such offering prospectus will contain
the information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other Items of the applicable form.

  (2) The Registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

  (3) Insofar as the indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to Directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

  (4) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through
the date of responding to the request.

  (5) 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.

                                      II-3

  (6) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
