         QUESTIONS AND ANSWERS ABOUT THE MAPQUEST/AMERICA ONLINE MERGER

Q:  Why are we proposing to merge? (see page 28)

A:  Our merger will result in MapQuest stockholders becoming stockholders of
    America Online through the exchange of their MapQuest common stock for
    America Online common stock on what the MapQuest board of directors
    believes are favorable terms.

   By combining with America Online, MapQuest can benefit from America Online's
   substantial human, financial, marketing and technological resources as well
   as its significant presence on the Internet and broad customer base. We
   expect this combination will:

  .  expand the reach of MapQuest products to new customers and into new
     markets, and

  .  provide new cross-promotion and branding opportunities for MapQuest and
     America Online

Q:  What will I receive in the merger? (see page 38)

A:  If the merger is completed, you will receive 0.31558 of a share of America
    Online common stock for each share of MapQuest common stock you own. This
    fraction is referred to as the "exchange ratio." The number of shares of
    America Online common stock to be issued for each share of MapQuest common
    stock is fixed and will not be adjusted based upon changes in the value of
    America Online's shares. As a result, the value of the shares you receive
    in the merger will not be known at the time you vote on the merger and may
    go up or down as the market price of America Online common stock goes up or
    down. MapQuest is not permitted to "walk away" from the merger or resolicit
    the vote of its stockholders based solely on changes in the value of
    America Online common stock. In addition, instead of issuing any fractional
    shares of common stock, America Online will pay you cash based on the
    average closing price per share of America Online common stock on the New
    York Stock Exchange for the 20 consecutive trading days ending on the third
    trading day before the completion of the merger.

Q:  What effect will America Online's proposed merger with Time Warner have on
    me?

A:  America Online and Time Warner have entered into a merger agreement
    pursuant to which America Online and Time Warner would become wholly owned
    subsidiaries of a new parent company called AOL Time Warner Inc. We expect
    to complete our merger before this proposed merger with Time Warner is
    completed. If that is the case, you would receive shares of America Online
    common stock in our merger and, if the merger with Time Warner is approved
    and completed, each of those shares would be converted into one share of
    common stock of AOL Time Warner. If the Time Warner merger is completed
    before our merger, we would still expect to complete our merger, subject to
    the terms and conditions of our merger agreement, but instead of America
    Online common stock, you would receive 0.31558 of a share of AOL Time
    Warner common stock in our merger.

Q:  What stockholder approvals are needed?

A:  For America Online, no approval of stockholders is needed and no vote will
    be taken.

  For MapQuest, the affirmative vote of the holders of at least a majority of
  the aggregate voting power of MapQuest's common stock outstanding and
  entitled to vote at the special meeting is required to adopt the merger
  agreement. Stockholders of MapQuest owning approximately 72.8% of the
  outstanding MapQuest common stock on the record date are parties to a
  stockholders agreement with America Online, in which they have agreed to
  vote all these shares in favor of the adoption of the merger agreement.
  Therefore, the approval of the proposal to adopt the merger agreement by a
  majority of the stockholders of MapQuest is certain.

Q: What do I need to do now?

A: After carefully reading and considering the information contained in this
   proxy statement/prospectus, please respond by completing, signing and dating
   your proxy card and returning it in the enclosed postage paid envelope, or,
   if available, by submitting your proxy by telephone or through the Internet,
   as soon as possible, so that your shares may be represented at the special
   meeting.

Q: What if I don't vote?

A: .If you fail to respond, it will have the same effect as a vote against the
   merger.

  . If you respond and do not indicate how you want to vote, your proxy will
    be counted as a vote in favor of the merger.

  . If you respond and abstain from voting, your proxy will have the same
    effect as a vote against the merger.

Q: Can I change my vote after I have delivered my proxy?

A: Yes. You can change your vote at any time before your proxy is voted at the
   special meeting. You can do this in one of three ways. First, you can revoke
   your proxy. Second, you can submit a new proxy. If you choose either of
   these two methods, you must submit your notice of revocation or your new
   proxy to the secretary of MapQuest before the special meeting. If your
   shares are held in an account at a brokerage firm or bank, you should
   contact your brokerage firm or bank to change your vote. Third, if you are a
   holder of record, you can attend the special meeting and vote in person. If
   you submit your proxy or voting instructions electronically through the
   Internet or by telephone, you can change your vote by submitting a proxy or
   voting at a later date, using the same procedures, in which case your later
   submitted proxy or vote will be recorded and your earlier proxy or vote
   revoked.

Q: Should I send in my stock certificates now?

A: No. After the merger is completed, you will receive written instructions
   from the exchange agent on how to exchange your stock certificates for
   shares of America Online. Please do not send in your stock certificates with
   your proxy.

Q: Who is the exchange agent for the merger?

A: EquiServe Trust Company, N.A. is the exchange agent.

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

A: We are working to complete the merger as quickly as possible. We expect to
   complete the merger in June 2000.

Q: Who can help answer my questions?

A: If you have any questions about the merger or how to submit your proxy, or
   if you need additional copies of this proxy statement/prospectus or the
   enclosed proxy card or voting instructions, you should contact:

leader in network computing products and services, to accelerate the growth of
electronic commerce. Through the alliance, the two companies develop and market
to business enterprises, client software and network application and server
software for electronic commerce, extended communities and connectivity,
including software based in part on the Netscape Enterprise Group code base, on
Sun code and technology and on certain America Online services features.

   Recent Developments. On March 17, 2000, America Online and Bertelsmann AG
announced a global alliance to expand the distribution of Bertelsmann's media
content and electronic commerce properties over America Online's interactive
brands worldwide. America Online and Bertelsmann also announced an agreement to
restructure their interests in the AOL Europe and AOL Australia joint ventures.
This restructuring consists of a put and call arrangement for America Online to
purchase, in two installments, Bertelsmann's 50% interest in AOL Europe for
consideration ranging from $6.75 billion to $8.25 billion, payable at America
Online's option in cash, America Online stock (or AOL Time Warner stock, if the
merger between America Online and Time Warner has closed) or a combination of
cash and stock. Bertelsmann has the right to require America Online to purchase
80% of its 50% interest in AOL Europe on January 31, 2002 for $5.3 billion and
the remainder on July 1, 2002 for $1.45 billion. If Bertelsmann fails to
exercise its put rights, America Online has the right to purchase 80% of
Bertelsmann's 50% interest in AOL Europe between January 15, 2002 and January
15, 2003 for $6.5 billion and the remainder between June 30, 2002 and June 30,
2003 for $1.75 billion. In addition, the parties agreed that America Online
would take immediate ownership of Bertelsmann's 50% interest in the parties'
AOL Australia joint venture, subject to receipt of necessary regulatory
approvals. Because Bertelsmann's first put option will not close until January
31, 2002, if exercised, America Online has not determined yet how it will fund
the payment of the purchase price for its purchases of Bertelsmann's interest
in AOL Europe. America Online cannot predict if Bertelsmann will exercise its
put rights and America Online's call rights are not exercisable unless
Bertelsmann fails to exercise its put rights. If Bertelsmann does not exercise
its put rights, America Online will consider all pertinent factors at such time
and during the exercisability period of its call rights in determining whether
to exercise its call rights, including the performance and perceived value of
AOL Europe at such time, conditions in the markets where AOL Europe operates,
financial market conditions and America Online's (or AOL Time Warner's)
business plans and financial situation. For the year ended June 30, 1999, AOL
Europe's revenues are less than 10% of America Online's revenues and AOL
Europe's net loss is less than 5% of American Online's net income. America

Online anticipates that the primary impact of the potential acquisition of
Bertelsmann's interest in AOL Europe on results of operations would be the
amortization of $1 billion to $1.5 billion of goodwill each year. America
Online does not anticipate an adverse impact from the potential acquisition on
America Online's financial position because it will have the ability to pay the
purchase price either in stock or cash, or a combination of the two, at its
option. America Online believes it will have adequate resources from its cash
reserves or from accessing the capital markets to make the required payment
upon exercise of a put or call right, should it decide to pay in cash, and that
following the Time Warner merger, AOL Time Warner will be in a stronger
position to make such payments than America Online alone would be.

   On January 10, 2000, America Online entered into a merger agreement with
Time Warner Inc. pursuant to which each of America Online and Time Warner would
become wholly owned subsidiaries of a new parent company named AOL Time Warner
Inc. In that merger, subject to the terms and conditions of the merger
agreement with Time Warner, each share of America Online common stock will be
converted into one share of AOL Time Warner common stock and each share of Time
Warner common stock and series common stock will be converted into 1.5 shares
of AOL Time Warner common stock and series common stock, respectively, and each
share of Time Warner preferred stock will be converted into a substantially
identical share of AOL Time Warner preferred stock. If both our merger and the
merger with Time Warner occur, you will become a stockholder of AOL Time
Warner, whose business will consist of the current businesses of America Online
and Time Warner.

   The merger with Time Warner is subject to a number of conditions and America
Online expects to complete its merger with MapQuest before its merger with Time
Warner. AOL Time Warner has filed a registration statement on Form S-4 relating
to the merger with Time Warner. You are encouraged to read that document and
the documents filed by America Online with the Securities and Exchange
Commission that are incorporated herein by reference. See "Where You Can Find
More Information" that begins on page 89.

   America Online has been named as a defendant in several class action
lawsuits that have been filed in state and federal courts. The complaints in
these lawsuits contend that consumers and competing Internet service providers
have been injured because of the default selection features in AOL 5.0. These
cases are at a preliminary stage, but America Online does not believe they have
merit and intends to contest them vigorously.

Summary of the Transaction

  Stockholder Actions Required for the Transaction To Be Completed (see page 22)

   The merger agreement must be adopted by MapQuest's stockholders for the
merger to occur. MapQuest has called the special meeting of stockholders to
which this proxy statement/prospectus relates so MapQuest stockholders can vote
on whether to adopt the merger agreement. The stockholders meeting will be held
on June 26, 2000 at 10:00 a.m. local time, at Mayer, Brown & Platt, 1675
Broadway, New York, New York.

   You may vote in person at the meeting or by proxy by following the
instructions provided. You will be entitled to one vote for each share of
MapQuest common stock you hold. Holders of shares representing a majority of
the aggregate voting power of the shares of MapQuest common stock entitled to
vote at the special meeting must vote in favor of the proposal to adopt the
merger agreement for the merger to occur. Consequently, abstentions, failures
to vote, and broker non-votes have the same effect as a vote against adoption
of the merger agreement. If the stockholders vote to adopt the merger agreement
and the merger

                                       6
<PAGE>

occurs, MapQuest common stock will be exchanged for shares of America Online
common stock based on the exchange ratio of 0.31558 of a share of America
Online common stock for each share of MapQuest common stock. Following the
merger, the exchange agent will send to each stockholder of record on the
closing date instructions on how to exchange the shares of MapQuest common
stock for the appropriate number of shares of America Online common stock.

  Recommendation of MapQuest's Board of Directors (see page 30)

   After careful consideration, MapQuest's board of directors unanimously
determined the merger to be fair to you and in your best interests, and
declared the merger advisable. MapQuest's board of directors unanimously
approved the merger agreement and recommends its adoption by you.

  Opinion of MapQuest's Financial Advisor (see page 30 and Annex D)

   On December 21, 1999, FleetBoston Robertson Stephens Inc. ("Robertson
Stephens"), MapQuest's financial advisor, delivered its oral opinion,
subsequently confirmed in writing as of December 21, 1999, to MapQuest's board
of directors that, as of the date of its opinion and subject to the
considerations described in its opinion, the exchange ratio in the merger
agreement was fair from a financial point of view to MapQuest stockholders. The
complete opinion of Robertson Stephens is attached as Annex D. We urge you to
read it in its entirety.

  Structure of the Transaction (see page 38)

   MapQuest will merge with MQ Acquisition, a subsidiary of America Online, and
become a wholly owned subsidiary of America Online. Based on the exchange
ratio, MapQuest common stock will be exchanged for shares of America Online
common stock. Following the merger, as a stockholder of America Online, you
will have an equity stake in MapQuest's parent company, but will no longer have
any direct interest in MapQuest alone.

  Completion and Effectiveness of the Merger (see page 38 and Annex A)

   If and when a majority of MapQuest's stockholders vote in favor of the
adoption of the merger agreement and when all of the other conditions to
complete the merger are satisfied or waived, the merger will become effective
when we file a certificate of merger with the Secretary of State of the State
of Delaware. The merger agreement is attached as Annex A. We urge you to read
it in its entirety.

  Conditions to Completion of the Merger (see page 43)

   Our respective obligations to complete the merger are subject to the prior
satisfaction or waiver of the conditions listed below. If either America Online
or MapQuest waives any of the conditions, MapQuest will consider the facts and
circumstances at that time and make a determination as to whether a
resolicitation of proxies from MapQuest stockholders is appropriate. The
conditions that must be satisfied or waived before the merger is completed
include the following:

  .  the merger agreement must be adopted by MapQuest's stockholders,

  .  all applicable approvals and consents required to complete the merger
     must be received and all applicable waiting periods under applicable
     antitrust laws must have expired or been terminated,

  .  no injunction or order preventing the completion of the merger may be in
     effect,

  .  our respective representations and warranties in the merger agreement
     must be true and correct, including the absence of material adverse
     changes in MapQuest's business,

  .  we must have complied with our respective covenants and agreements in
     the merger agreement,


                                       7
<PAGE>

  .  MapQuest must obtain any required consents from third parties relating
     to the merger, except where the failure to obtain these consents would
     not reasonably be expected to have a material adverse effect on
     MapQuest's business, condition, financial or otherwise, results of
     operations, assets, liabilities, properties or prospects of MapQuest and
     its subsidiaries, taken as a whole,

  .  we must each receive an opinion of tax counsel to the effect that the
     merger will qualify as a tax-free reorganization,

  .  America Online must be advised in writing by Ernst & Young LLP, its
     independent auditors, that they concur with America Online's conclusion
     that the merger can properly be accounted for as a pooling-of-interests
     business combination,

  .  the shares of America Online common stock to be issued to MapQuest
     stockholders in the merger must have been approved for listing on the
     New York Stock Exchange,

  .  specified related agreements must be in full force and effect as of the
     completion of the merger, and

  .  an employment offer letter between specified employees of MapQuest and
     America Online, or reasonably acceptable replacement employees, must be
     in full force and effect as of the completion of the merger.

  Termination of the Merger Agreement (see page 48)

   The merger agreement may be terminated at any time before the completion of
the merger under the circumstances summarized below.

   The merger agreement may be terminated by our mutual consent.

   The merger agreement may also be terminated by either America Online or
MapQuest if the conditions to completion of the merger would not be satisfied
because of a material breach of any agreement or covenant or any representation
or warranty in the merger agreement by the other becomes untrue or inaccurate
and cannot be cured or is not cured within 30 days.

   In addition, the merger agreement may be terminated by either of America
Online or MapQuest under any of the following circumstances:

  .  if the merger is not completed by June 30, 2000, although this date will
     be extended to September 30, 2000 if the applicable waiting periods and
     necessary approvals under the antitrust laws have not been received or
     have not expired or been terminated,

  .  if a final court order or governmental order prohibiting the merger is
     issued and is not appealable, or

  .  if the MapQuest stockholders do not adopt the merger agreement at the
     special meeting.

   Furthermore, America Online may terminate the merger agreement if MapQuest's
board of directors takes any of the following actions:

  .  approves or recommends, or proposes, resolves or announces an intention
     to approve or recommend, an extraordinary transaction of the nature
     specified in the merger agreement involving MapQuest and a party other
     than America Online, such as a merger, other business combination,
     issuance or acquisition of 20% or more of the outstanding voting capital
     stock of MapQuest or a sale of a significant portion of MapQuest's
     business or assets, including its intellectual property,

  .  fails to present the merger agreement to the MapQuest stockholders and
     recommend that the MapQuest stockholders adopt and approve the merger
     agreement, or withdraws or modifies its

                                       8
<PAGE>

     recommendation in a manner adverse to America Online, proposes, resolves
     or announces its intention to do so,

  .  fails to mail this proxy statement/prospectus when it is available for
     mailing or fails to include in it the board's recommendation of the
     merger, including the recommendation that the MapQuest stockholders vote
     in favor of the adoption of the merger agreement, or resolves or
     announces its intention to fail to do so,

  .  upon a request by America Online, fails to publicly reaffirm its
     approval and recommendation of the merger and the merger agreement, or
     resolves or announces its intention to fail to do so,

  .  takes any action prohibited by the covenant, described under
     "Solicitation of Other Proposals Involving MapQuest" below, or enters
     into any letter of intent, agreement in principle, acquisition agreement
     or other similar agreement related to an extraordinary transaction of
     the nature specified in the merger agreement involving MapQuest and a
     party other than America Online, such as a merger, other business
     combination, issuance or acquisition of 20% or more of the outstanding
     voting capital stock of MapQuest or a sale of a significant portion of
     MapQuest's assets, including its intellectual property, or resolves or
     announces its intention to do so, or

  .  materially breaches the stock option agreement (described under
     "MapQuest Has Entered into a Stock Option Agreement with America Online"
     below and attached as Annex B).

   America Online may also terminate the merger agreement if:

  .  a third party acquires 20% or more of the outstanding shares of capital
     stock or other equity interests of MapQuest, or

  .  there occurs a material breach of any representation, warranty, covenant
     or agreement contained in the stockholders agreement (described under
     "Some MapQuest Stockholders Have Entered into a Stockholders Agreement"
     below and attached as Annex C) by any of the stockholders of MapQuest
     who are parties to the stockholders agreement that would reasonably be
     expected to have a material adverse effect on or materially impede the
     ability of the parties to consummate the merger as contemplated by the
     merger agreement.

  Payment of Termination Fee and Expenses (see page 49)

   MapQuest has agreed to pay America Online a termination fee of $34.6 million
if the merger agreement is terminated by America Online because of any of the
following circumstances:

  .  the MapQuest stockholders do not adopt the merger agreement at the
     special meeting,

  .  MapQuest's board of directors takes any of the actions described in the
     fifth paragraph under "Termination of the Merger Agreement" above,

  .  a third party acquires beneficial ownership of 20% or more of the
     outstanding shares of capital stock or other equity interests of
     MapQuest,

  .  any of the stockholders of MapQuest who are parties to the stockholders
     agreement materially breach any representation, warranty, covenant or
     agreement contained in the stockholders agreement in a manner that would
     reasonably be expected to have a material adverse effect on or
     materially impede the ability of the parties to consummate the merger,
     or

  .  MapQuest willfully and materially breaches any covenant or agreement
     contained in the merger agreement.


                                       9
<PAGE>

   In addition, if the merger agreement is terminated in circumstances in which
the termination fee described above becomes payable or because MapQuest
materially breaches the merger agreement and such breach is not cured by
MapQuest within 30 days, MapQuest has agreed to pay America Online up to $2.5
million of fees and expenses actually incurred by America Online in connection
with the merger agreement and the merger.

  Solicitation of Other Proposals Involving MapQuest (see page 46)

   Until the merger is completed or the merger agreement is terminated,
MapQuest has agreed not to directly or indirectly take any of the following
actions:

  .  solicit, facilitate, initiate, entertain or encourage, or take any
     action to solicit, facilitate, initiate, entertain or encourage, any
     inquiries or communications or the making of any proposal or offer for
     any extraordinary transaction involving MapQuest and a party other than
     America Online of the nature specified in the merger agreement, such as
     a merger, other business combination, issuance or acquisition of 20% or
     more of the outstanding voting capital stock of MapQuest or a sale of
     any significant portion of MapQuest's business or assets, including its
     intellectual property, or

  .  with respect to any person, entity or group that is pursuing such an
     extraordinary transaction, participate or engage in any discussions or
     negotiation with, or provide any information relating to MapQuest or
     take any other action with the intent to facilitate the efforts of, any
     person, entity or group concerning any such proposal or offer.

   However, MapQuest may participate or engage in discussions or negotiations
or furnish information with respect to MapQuest if all of the following occur:

  .  the third party has submitted to MapQuest's board of directors an
     unsolicited, bona fide written proposal regarding an extraordinary
     transaction of the nature specified in the merger agreement,

  .  MapQuest has not violated its covenants regarding extraordinary
     transactions described above,

  .  MapQuest's board of directors determines in its good faith judgment,
     after consultation with outside counsel, that taking such action is
     required to satisfy the MapQuest board's fiduciary duties under
     applicable law, and

  .  MapQuest enters into a confidentiality agreement with the third party in
     connection with the disclosure of information relating to MapQuest and
     provides America Online with prior written notice of any action it
     takes.

   In addition, until the merger is completed or the merger agreement is
terminated, the board of directors of MapQuest has agreed not to take any of
the following actions:

  .  approve or recommend, or propose to approve or recommend, any proposal
     regarding an extraordinary transaction of the nature specified in the
     merger agreement, other than the merger,

  .  withdraw or modify or propose to withdraw or modify in a manner adverse
     to America Online its approval or recommendation of the merger, the
     merger agreement or the transactions contemplated by the merger
     agreement,

  .  upon a request by America Online to reaffirm its approval or
     recommendation of the merger, fail to do so within two business days
     after such request is made,

  .  approve, enter, or permit or cause MapQuest to enter, into any letter of
     intent, agreement in principle, acquisition agreement or other similar
     agreement related to any proposal regarding an extraordinary transaction
     of the nature specified in the merger agreement, or

  .  resolve or announce its intention to do any of the foregoing.

                                       10
<PAGE>


   However, if prior to the MapQuest stockholders' meeting the board of
directors of MapQuest receives a proposal to effect a merger, consolidation or
sale of all or substantially all of the assets or capital stock of MapQuest
which is on terms which the MapQuest board of directors determines in good
faith, based on the written opinion of its financial advisor that the
consideration provided in such proposal likely exceeds the value of the
consideration provided for in the merger, to be more favorable to MapQuest's
stockholders than the merger or any revised proposal made by America Online,
the MapQuest board of directors may take any of the following actions, if after
consultation with outside counsel, the MapQuest board of directors determines
in good faith that taking such action is required to satisfy the fiduciary
duties of the MapQuest board under applicable law:

  .  withdraw or modify, or propose to withdraw or modify, in a manner
     adverse to America Online, its approval or recommendation of the merger
     or the merger agreement,

  .  fail to reaffirm its approval or recommendation of the merger or the
     merger agreement after a request by America Online to do so, or

  .  resolve or announce its intention to take any of the foregoing actions.

  MapQuest Has Entered into a Stock Option Agreement with America Online (see
  page 53 and Annex B)

   MapQuest entered into a stock option agreement with America Online, which
grants America Online the option to buy up to 3,571,661 shares of MapQuest
common stock, which represents approximately 10.0% of the shares and
approximately 10.0% of the voting power of MapQuest common stock outstanding on
December 21, 1999 or approximately 9.1% of the shares and approximately 9.1% of
the voting power of the shares after issuance of the shares of MapQuest common
stock subject to the option. The exercise price of the option is $27.00 per
share. America Online's maximum profit under the stock option agreement is
$34.6 million, less any termination fee paid by MapQuest under the merger
agreement.

   America Online requested MapQuest to grant the option as a prerequisite to
entering into the merger agreement. The option may discourage third parties who
are interested in acquiring a significant stake in MapQuest and is intended by
America Online to increase the likelihood that the merger will be completed.

   The option is not currently exercisable and America Online may only exercise
the option if the merger agreement is terminated under circumstances in which
the termination fee is payable (as described under "Payment of Termination
Fees" on page 49). If the merger agreement is terminated under circumstances in
which the termination fee could not become payable, the option will terminate
and America Online may not exercise it.

   You are urged to read the stock option agreement in its entirety.

  Some MapQuest Stockholders Have Entered into a Stockholders Agreement (see
  page 54 and Annex C)

   Certain MapQuest stockholders have entered into a stockholders agreement
with America Online. The stockholders agreement requires these MapQuest
stockholders to vote all shares of MapQuest common stock beneficially owned by
them in favor of the adoption of the merger agreement. These MapQuest
stockholders were not paid additional consideration in connection with the
stockholders agreement.

   The MapQuest stockholders who entered into the stockholders agreement
collectively held approximately 72.8% of the outstanding MapQuest common stock
on the record date. Therefore, the approval of the proposal to adopt the merger
agreement by a majority of the stockholders of MapQuest is certain.

   You are urged to read the stockholders agreement in its entirety.

  America Online, Digital City, Inc., a Subsidiary of America Online, and
  MapQuest Have Entered into a Distribution Agreement (see page 55)

   America Online, Digital City and MapQuest entered into a distribution
agreement simultaneously with the merger agreement under which MapQuest will
provide America Online and Digital City the use and license of its mapping and
routing data and services for use over the AOL network and with the Digital
City service. The distribution agreement became effective on December 21, 1999.
America Online will pay MapQuest an annual fee based on the amount of revenue
generated as a result of the use of MapQuest's products and services. The
agreement has a term of five years with America Online having the right to
extend the term for up to three additional years except that, with respect to
specific services that MapQuest is to provide to Digital City, the agreement
will expire on March 31, 2001. The parties' obligations and rights under the
distribution agreement are independent of their rights and obligations under
the merger agreement or the other agreements related to the merger and will
remain in effect notwithstanding any termination or amendment of the merger
agreement or the other agreements related to the merger.

  Interests of Certain Persons in the Merger (see page 37)

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

   In particular, the three executive officers of MapQuest have signed letters
which contain offers of employment from America Online that will become
effective upon the completion of the merger. These officers are identified
under "Interests of Certain MapQuest Directors and Officers in the Merger" on
page 37. In addition, all unvested stock options granted under MapQuest's 1995
Stock Option Plan, including options granted to the executive officers of
MapQuest, vested upon the announcement of the merger in accordance with
existing plan provisions.

   As of May 16, 2000, directors and executive officers of MapQuest and their
affiliates beneficially owned 29,093,592 shares, including stock options
exercisable within 60 days of May 16, 2000, which number of shares represents
approximately 74.1% of the outstanding shares of MapQuest common stock as of
that date. Furthermore, certain MapQuest executive officers have signed, in
their capacity as stockholders, a stockholders agreement in which they have
agreed to vote their shares in favor of adopting the merger agreement.

  U.S. Federal Income Tax Consequences of the Merger (see page 39)

   We have structured the merger so that, in general, America Online, MapQuest
and their respective stockholders will not recognize gain or loss for United
States federal income tax purposes in connection with the merger, except with
respect to cash received by MapQuest stockholders instead of fractional shares.

  Accounting Treatment of the Merger (see page 41)

   We intend to account for the merger as a pooling-of-interests business
combination. It is a condition to completion of the merger that America Online
be advised in writing by Ernst & Young LLP that they concur with America
Online's conclusion that the merger can properly be accounted for as a pooling-
of-interests business combination. Although this condition may be waived by
America Online, it is unlikely that America Online would waive this condition.
Under the pooling-of-interests method of accounting, each of our historical
recorded assets and liabilities will be carried forward to the combined company
at their recorded amounts.

  Antitrust Approval Required to Complete the Merger (see page 41)

   The merger is subject to antitrust laws. We have made the required filings
with the Department of Justice and the Federal Trade Commission. In addition,
we have made the required filing in connection with the merger with regulatory
authorities in Germany. We are not permitted to complete the merger until the
applicable waiting periods have expired or been terminated. The applicable
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act expired
on February 27, 2000, and the regulatory authorities in Germany approved the
merger on May 5, 2000. The Department of Justice or the Federal Trade
Commission and any state antitrust authority may challenge the merger at any
time before its completion.

  Restrictions on the Ability to Sell America Online Stock (see page 41)

America Online, (2) selected unaudited pro forma consolidated financial data
giving effect to America Online's pending merger with Time Warner and (3)

   Significant Events Affecting America Online's Operating Trends. The
comparability of America Online's operating results is affected by a number of
significant and nonrecurring items recognized in some periods. For the nine
months ended March 31, 2000, America Online incurred a special charge of $5
million related to a

                                       14
<PAGE>


merger and gains of $386 million related to investments. In fiscal 1999,
America Online incurred special charges of $95 million related to mergers and a
restructuring, $25 million in transition costs and a net gain of $567 million
related to the sale of investments in Excite, Inc. In fiscal 1998, America
Online incurred special charges of $94 million for acquired in-process research
and development, $17 million related to settlements and $75 million related to
a merger and restructuring. In fiscal 1997, America Online incurred special
charges of $49 million related to a restructuring, $24 million for contract
terminations, $24 million for a legal settlement and $9 million related to
acquired in-process research and development. In fiscal 1996, America Online
incurred special charges of $17 million for acquired in-process research and
development, $8 million in merger related costs and $8 million for the
settlement of a class action lawsuit. In fiscal 1995, America Online incurred
special charges of $2 million for merger related costs and $50 million for
acquired in-process research and development.

   To assess meaningfully underlying operating trends from period to period,
America Online's management believes that the results of operations for each
period should be analyzed after excluding the effects of these significant
nonrecurring items. Where noted, the following summary adjusts America Online's
historical operating results to exclude the impact of these unusual items.
However, unusual items may occur in any period. Accordingly, investors and
other financial statement users should consider the types of events and
transactions for which adjustments have been made.

(1) EBITDA is defined as net income plus: (a) provision/(benefit) for income
  taxes, (b) interest, (c) depreciation and amortization and (d) special items.
  America Online considers EBITDA to be an important indicator of the
  operational strength and performance of its business, including its ability
  to provide cash flows to service its debt and fund capital expenditures.
  EBITDA, however, should not be considered an alternative to operating or net
  income as an indicator of America Online's performance, or as an alternative
  to cash flows from operating activities as a measure of liquidity, in each
  case determined in accordance with generally accepted accounting principles.
  In addition, this definition of EBITDA may not be comparable to similarly
  titled measures reported by other companies.

                                AOL TIME WARNER

            Selected Unaudited Pro Forma Consolidated Financial Data

   The selected unaudited pro forma consolidated financial data of AOL Time
Warner, the resulting company from America Online's proposed merger with Time
Warner, have been derived from the unaudited pro forma consolidated condensed
financial statements incorporated by reference in this proxy
statement/prospectus. Because America Online and Time Warner have different
fiscal years, and the combined company will adopt the calendar year-end of Time
Warner, pro forma operating results are presented on two different bases:

  .  a June 30 fiscal-year basis, which is consistent with America Online's
     historical fiscal year-end, and

  .  a December 31 calendar-year basis, which is consistent with both Time
     Warner's historical fiscal year-end and that of AOL Time Warner going
     forward.

We believe that it is meaningful to present pro forma financial information
based on the calendar year-end of the combined company to facilitate an
analysis of the pro forma effects of the merger between America Online and Time
Warner.

(1)  EBITDA consists of business segment operating income (loss) before
     depreciation and amortization. AOL Time Warner considers EBITDA to be an
     important indicator of the operational strength and performance of its
     businesses, including the ability to provide cash flows to service debt
     and fund capital expenditures. EBITDA, however, should not be considered
     an alternative to operating or net income as an indicator of the

     this definition of EBITDA may not be comparable to similarly titled
     measures reported by other companies.

(2)  EBITDA includes a number of significant and nonrecurring items. The

Comparative Per Share Market Price Data

   America Online common stock is traded on the New York Stock Exchange under
the symbol "AOL," and MapQuest common stock is traded on the Nasdaq National
Market under the symbol "MQST."

   The following table sets forth the closing prices per share of MapQuest
common stock as reported on the Nasdaq National Market and the closing prices
per share of America Online common stock as reported on the New York Stock
Exchange on (1) December 21, 1999, the last full trading day before the public
announcement that America Online and MapQuest had entered into the merger
agreement and (2) May 22, 2000, the last full trading day for which it was
practicable to obtain closing prices at the time of the printing of this
proxy statement/prospectus.

   The following table also sets forth, in the column titled "Equivalent Per
Share Price," the value you would have received for each share of MapQuest
common stock you own, if the merger had been completed and you had exchanged
your shares of MapQuest common stock for shares of America Online common stock,
on the dates listed. The value was calculated by multiplying the exchange ratio
by the closing price of America Online common stock on the dates listed below.

   Because the market price of America Online common stock may increase or

market quotations.

                                  RISK FACTORS

   In addition to the other information contained in or incorporated by
reference into this joint proxy statement-prospectus, you should carefully
consider the following risk factors in deciding whether to vote for adoption of
the merger agreement.

The Value of the America Online Common Stock You Receive in the Merger May Vary

   Upon completion of the merger, each share of MapQuest common stock will be
converted into 0.31558 of a share of America Online common stock. This exchange
ratio is fixed and there will be no adjustment in the event of fluctuation in
the market price of either MapQuest common stock or America Online Common
Stock, and neither party is permitted to "walk away" from the merger because of
changes in either party's stock price. As a result, the value of the shares you
receive in the merger will not be known at the time you vote on the merger and
may go up or down as the market price of America Online common stock goes up or
down. The specific dollar value of America Online common stock to be received
by you upon completion of the merger will depend on the market value of America
Online common stock at the time of completion of the merger. As of May 22,
2000, the last trading date for which it was practicable to obtain information
before the printing of this proxy statement/prospectus, the closing price of
America Online common stock was $52.25 per share. The share prices of both
MapQuest common stock and America Online common stock are by nature subject to
the general price fluctuations in the market for publicly traded equity
securities and have experienced significant volatility. No prediction can be
made as to the market prices of either MapQuest common stock or America Online
common stock at any time before the completion of the merger or as to the
market price of America Online common stock after the completion of the merger.

America Online Has Entered into a Merger Agreement with Time Warner

   America Online has entered into a merger agreement with Time Warner Inc.
pursuant to which each of America Online and Time Warner would become wholly
owned subsidiaries of a new parent company named AOL Time Warner. In that
merger, subject to the terms and conditions of the merger agreement with Time
Warner, each share of America Online common stock will be converted into one
share of AOL Time Warner common stock, and each share of Time Warner common
stock and series common stock will be converted into 1.5 shares of AOL Time
Warner common stock and series common stock, respectively, and each share of
Time Warner preferred stock will be converted into a substantially identical
share of AOL Time Warner preferred stock. If both our merger and the merger
with Time Warner occur, you will become a stockholder of AOL Time Warner, whose
business will consist of the current businesses of America Online and Time
Warner.

   The merger with Time Warner is subject to a number of conditions, and
America Online expects to complete its merger with MapQuest before its merger
with Time Warner. There can be no assurance that the merger with Time Warner
will occur or, if it does occur, of what effect it will have on the stock
price, results of operations or financial condition of America Online or AOL
Time Warner. AOL Time Warner has filed a registration statement on Form S-4
relating to America Online's merger with Time Warner. You are encouraged to
read that document and the documents filed by America Online with the
Securities and Exchange Commission that are incorporated herein by reference.
See "Where You Can Find More Information" on page 89.

MapQuest Officers and Directors Have Conflicts of Interest Relating to Their
Approval and Support of the Merger

   The directors and executive officers of MapQuest have interests in the
merger that are different from, or are in addition to, yours. In particular,
the three executive officers of MapQuest have signed letters containing offers
of employment from America Online that will become effective upon the
completion of the merger. These offer letters in the aggregate contain a
commitment to grant to these executive officers options to purchase a total of
400,000 shares of America Online common stock. These executive officers are
identified under "Interests of Certain MapQuest Directors and Officers in the
Merger" on page 37.

                                       19
<PAGE>

   The continuation of indemnification arrangements for current directors of
MapQuest following completion of the merger, may influence these directors in
making their recommendation that you vote in favor of the adoption of the
merger agreement.

   In addition, all unvested stock options granted under MapQuest's 1995 Stock
Option Plan to all executive officers and employees of MapQuest vested upon
the announcement of the merger in accordance with the existing plan
provisions. The number of shares of MapQuest common stock subject to unvested
options held by MapQuest's executive officers that vested upon announcement of
the merger totaled 972,001 on December 21, 1999. Unvested stock options
outstanding under MapQuest's 1999 Stock Plan did not vest upon the
announcement of the merger.

   Furthermore, certain MapQuest executive officers have signed, in their
capacity as stockholders, a stockholders agreement in which they have agreed
to vote their shares in favor of adopting the merger agreement.

   As of May 16, 2000, directors and executive officers of MapQuest and their
affiliates beneficially owned 29,093,592 shares, including stock options
exercisable within 60 days of May 16, 2000, which number of shares represents
approximately 74.1% of the outstanding shares of MapQuest common stock as of
that date.

Parties to Contracts With MapQuest May Be Competitors of America Online Which
May Impact Their Decision Whether to Renew Their Contracts with MapQuest

   MapQuest has contracts with parties which may be competitors or companies
affiliated with competitors of America Online. These contracts provide for:

  .  license of MapQuest software, data and services for use by Internet
     search and directory sites,

  .  display, marketing and distribution of MapQuest mapping and routing
     content on Internet search and directory sites, and

  .  link from third-party networks to MapQuest's website.

   The merger of MapQuest with America Online may affect the likelihood of
contract renewals or negotiation of new contracts between these parties and
MapQuest. Failure of these parties to renew or enter into new agreements with
MapQuest could impair America Online's ability to realize the expected
benefits of the merger.

Failure to Complete the Merger Could Negatively Impact MapQuest's Stock Price
and Future Business and Operations

   If the merger is not completed for any reason, MapQuest may be subject to
the following material risks:

  .  MapQuest may be required to pay America Online a termination fee of
     $34.6 million, plus up to $2.5 million of expenses incurred by America
     Online,

  .  the option exercisable for up to 3,571,661 shares of MapQuest common
     stock granted to America Online by MapQuest may become exercisable,

  .  the price of MapQuest common stock may decline to the extent that the
     current market price of MapQuest common stock reflects a market
     assumption that the merger will be completed, and

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

   If the merger is terminated and MapQuest's board of directors determines to
seek another merger or business combination, there can be no assurance that it
will be able to find a partner willing to pay an equivalent or more attractive
price than that which would be paid in the merger. In addition, while the
merger agreement is in effect and subject to the limited exceptions described
on page 46 of this proxy

                                      20
<PAGE>

statement/prospectus, MapQuest is prohibited from soliciting, initiating,
entertaining, encouraging or facilitating or entering into certain
extraordinary transactions, such as a merger, sale of assets or other business
combination with any party other than America Online. Furthermore, if the
merger agreement is terminated and America Online exercises its option to
purchase MapQuest common stock, MapQuest would not be able to account for
future transactions as a pooling-of-interests.

Year 2000 Matters

   America Online utilizes a significant number of computer software programs
and operating systems across its entire organization, including applications
used in operating its online services and Web sites, the proprietary software
of the AOL and CompuServe services, Netscape software products, member and
customer services, network access, content providers, joint ventures and
various administrative and billing functions.

   In 1997, America Online appointed a Year 2000 Task Force to perform an audit
to assess the scope of America Online's risks and bring its applications into
compliance. This Task Force has overseen testing and is continuing its
assessment of America Online's company-wide compliance. America Online's system
hardware components, client and host software, current versions of Netscape
software products and corporate business and information systems have been
tested and continue to be reviewed. To date, America Online has experienced few
problems related to Year 2000 compliance, and the problems that have been
identified either have been addressed or are in the process of being addressed.
America Online is not aware of any remaining significant problems related to
Year 2000 issues but is continuing to monitor the status of suppliers and
vendors. There can be no assurance that America Online or one of the entities
it does business with will not experience a Year 2000 problem that could have
an effect on America Online.

   MapQuest has dedicated both internal and external resources to make the
required modifications and test Year 2000 compliance. To date, MapQuest has
experienced few problems related to Year 2000 compliance, and the problems that
have been identified either have been addressed or are in the process of being
addressed. MapQuest is not aware of any remaining significant problems related
to Year 2000 issues but is continuing to monitor the status of suppliers and
vendors. There can be no assurance that MapQuest or one of the entities it does
business with will not experience a Year 2000 problem that could have an effect
on MapQuest.

Anti-Takeover Provisions

   America Online's restated certificate of incorporation and restated by-laws
contain provisions that could make it more difficult for a third party to
acquire, or could discourage a third party from attempting to acquire, control
of America Online. These provisions allow America Online to issue preferred
stock with rights senior to those of its common stock and impose various
procedural and non-procedural requirements that could make it more difficult
for America Online stockholders to effect certain corporate actions.

   In addition, under America Online's stockholder rights plan, holders of
America Online common stock are entitled to one preferred share purchase right
for each outstanding share of common stock they hold, exercisable under certain
defined circumstances involving a potential change of control, as discussed
beginning on page 86 of this proxy statement/prospectus. The preferred share
purchase rights have the anti-takeover effect of causing substantial dilution
to a person or group that attempts to acquire America Online on terms not
approved by America Online's board of directors.

   In connection with America Online's merger agreement with Time Warner,
America Online granted to Time Warner an option to acquire shares of America
Online common stock in certain circumstances. If the option becomes
exercisable, it could restrict the ability of another person to acquire America
Online in a pooling-of-interests transaction.

   The foregoing provisions could have a material adverse effect on the premium
that potential acquirors might be willing to pay in an acquisition or that
investors might be willing to pay in the future for shares of America Online
common stock. However, in connection with America Online's merger with Time
Warner, AOL Time Warner will not have many of these anti-takeover provisions.

                  THE SPECIAL MEETING OF MAPQUEST STOCKHOLDERS

Proxy Statement/Prospectus

   This proxy statement/prospectus is being furnished to you in connection with
the solicitation of proxies by MapQuest's board of directors in connection with
our proposed merger.

   This proxy statement/prospectus is first being furnished to stockholders of
MapQuest on or about May 25, 2000.

Date, Time and Place of the Special Meeting

   The special meeting of stockholders of MapQuest is scheduled to be held as
follows:

       June 26, 2000

       10:00 a.m., local time

       Mayer, Brown & Platt

       1675 Broadway

       New York, New York 10019

Purpose of the Special Meeting

   The special meeting is being held so that stockholders of MapQuest may
consider and vote upon a proposal to adopt the Agreement and Plan of Merger,
dated as of December 21, 1999, as amended, by and among America Online, MQ
Acquisition, Inc., a wholly owned subsidiary of America Online, and MapQuest,
and to transact any other business that properly comes before the special
meeting or any adjournment. Adoption of the merger agreement will also
constitute approval of the merger and the other transactions contemplated by
the merger agreement.

   If the stockholders of MapQuest adopt the merger agreement, MQ Acquisition
will merge with and into MapQuest, and MapQuest will survive the merger as a
wholly owned subsidiary of America Online. You will receive 0.31558 of a share
of America Online common stock for each share of MapQuest common stock you
hold.

Stockholder Record Date for the Special Meeting

   MapQuest's board of directors has fixed the close of business on April 27,
2000 as the record date for determination of MapQuest stockholders entitled to
notice of and to vote at the special meeting. On the record date, there were
36,513,067 shares of MapQuest common stock outstanding, held by approximately
7,171 holders of record.

Majority Vote of MapQuest Stockholders Required for Adoption of the Merger
Agreement

   A majority of the outstanding voting power of the shares of MapQuest common
stock entitled to vote at the special meeting must be represented, either in
person or by proxy, to constitute a quorum at the special meeting. The
affirmative vote of the holders of at least a majority of the aggregate voting
power of MapQuest's common stock outstanding and entitled to vote at the
special meeting is required to adopt the merger agreement. You are entitled to
one vote for each share of MapQuest common stock held by you on the record date
on each proposal to be presented to stockholders at the special meeting.

   The MapQuest stockholders who are parties to the stockholders agreement,
which includes certain MapQuest executive officers, in their capacity as
stockholders, with America Online have agreed, subject to the terms and
conditions of the stockholders agreement, to vote their shares of MapQuest
common stock in favor

                                       22
<PAGE>


of the adoption of the merger agreement. As of the record date, these
stockholders held approximately 26,586,545 shares of MapQuest common stock.
These share numbers represented approximately 72.8% of the outstanding shares
of MapQuest common stock and approximately 72.8% of the voting power of the
outstanding shares of MapQuest common stock entitled to vote as of the record
date at the special meeting. Therefore, the approval of the proposal to adopt
the merger agreement by a majority of the stockholders of MapQuest is certain.

   On the record date for the special meeting, directors and executive officers
of MapQuest and their affiliates held approximately 26,371,002 shares of
MapQuest common stock. These share numbers represented approximately 72.2% of
all outstanding shares of MapQuest common stock and approximately 72.2% of the
voting power of the outstanding shares of MapQuest common stock entitled to
vote as of the record date at the special meeting.

Proxies

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

   If a properly executed proxy is returned and the stockholder has abstained
from voting on adoption of the merger agreement, the MapQuest common stock
represented by the proxy will be considered present at the special meeting for
purposes of determining a quorum, but will not be considered to have been voted
in favor of adoption of the merger agreement. If your shares are held in an
account at a brokerage firm or bank, you must instruct it on how to vote your
shares. If an executed proxy card is returned by a broker holding shares in the
name of a brokerage firm or bank, which indicates that the broker or bank does
not have discretionary authority to vote on adoption of the merger agreement,
the shares will be considered present at the meeting for purposes of
determining the presence of a quorum, but will not be considered to have been
voted in favor of adoption of the merger agreement. Your broker or bank will
vote your shares only if you provide instructions on how to vote by following
the information provided to you by your broker or bank.

   Because adoption of the merger agreement requires the affirmative vote of at
least a majority of the voting power of MapQuest's common stock outstanding on
the record date, abstentions, failures to vote and broker non-votes will have
the same effect as a vote against adoption of the merger agreement.

   MapQuest does not expect that any matter other than adoption of the merger
agreement will be brought before the special meeting. If, however, other
matters are properly presented, the persons named as proxies will vote in
accordance with their judgment with respect to those matters, unless authority
to do so is withheld in the proxy.

   You may revoke your proxy at any time before it is voted by:

  .  notifying in writing the Secretary of MapQuest at 3710 Hempland Road,
     Mountville, Pennsylvania 17554,

  .  granting a subsequent proxy,

  .  appearing in person and voting at the special meeting, or

  .  if you voted electronically through the Internet or by telephone,
     changing your vote by voting again at a later date, using the same
     procedures.

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

   America Online and MapQuest will equally share the expenses incurred in
connection with the printing and mailing of this proxy statement/prospectus.
MapQuest will request banks, brokers and other intermediaries

                                       23
<PAGE>

holding shares beneficially owned by others to send this proxy
statement/prospectus to and obtain proxies from the beneficial owners and will
reimburse the holders for their reasonable expenses in so doing.

   You should not send in any stock certificates with your proxies. A
transmittal form with instructions for the surrender of stock certificates for
MapQuest common stock will be mailed to you as soon as practicable after
completion of the merger.

Voting Electronically or by Telephone

   Because Delaware, the state in which MapQuest is incorporated, permits
electronic submission of proxies through the Internet or by telephone, instead
of submitting proxies by mail on the enclosed proxy card or voting
instructions, many stockholders may vote electronically by submitting their
proxies or voting instructions through the Internet or by telephone. Please
note that there are separate arrangements for using the Internet and telephone
depending on whether your shares are registered in MapQuest's stock records in
your name or in the name of a brokerage firm or bank. You should check your
proxy card or voting instructions forwarded by your broker, bank or other
holder of record to see which options are available.

   The Internet and telephone procedures described below for submitting your
proxy or voting instructions are designed to authenticate stockholders'
identities, to allow stockholders to have their shares voted and to confirm
that their instructions have been properly recorded. MapQuest has been advised
by counsel that the procedures that have been put in place are consistent with
the requirements of Delaware law. Stockholders submitting proxies or voting
instructions via the Internet should understand that there may be costs
associated with electronic access, such as usage charges from Internet access
providers and telephone companies, that would be borne by the stockholder.

   MapQuest holders of record may submit their proxies:

  .  through the Internet by visiting a website established for that purpose
     at www.proxyvoting.com and following the instructions; or

  .  by telephone by calling the toll-free number 800-676-5925 and following
     the recorded instructions.

Solicitation of Proxies

   America Online and MapQuest will equally share the expenses incurred in
connection with the printing and mailing of this proxy statement/prospectus.
MapQuest will also request banks, brokers and other intermediaries holding
shares of MapQuest common stock beneficially owned by others to send this proxy
statement/prospectus to, and obtain proxies from, the beneficial owners and
will reimburse the holders for their reasonable expenses in so doing.
Solicitation of proxies by mail may be supplemented by telephone, telegram and
other electronic means, advertisements and personal solicitation by the
directors, officers or employees of MapQuest. No additional compensation will
be paid to directors, officers or employees for such solicitation.

   You should not send in any stock certificates with your proxy card. A
transmittal letter with instructions for the surrender of stock certificates
will be mailed to you as soon as practicable after completion of the merger.

                                   THE MERGER

   This section of the proxy statement/prospectus describes material aspects of
the proposed merger, including the merger agreement, the stock option agreement
and the stockholders agreement. While we believe that the description covers
the material terms of the merger, this summary may not contain all of the
information that is important to you. You should read this entire proxy
statement/prospectus and the other documents we refer to carefully for a more
complete understanding of the merger. In addition, we incorporate important
business and financial information about America Online into this proxy
statement/prospectus by reference. You may obtain the information incorporated
by reference into this proxy statement/prospectus without charge by following
the instructions in the section entitled "Where You Can Find More Information"
on page 89 of this proxy statement/prospectus.

Background of the Merger

   America Online and MapQuest have been familiar with each other's business
for several years. In November 1997, Digital City, Inc., a subsidiary of
America Online, and MapQuest entered into an agreement under which MapQuest was
paid by Digital City to provide mapping and routing information and services to
Digital City. One year later, that agreement was terminated. In April 1999,
Digital City and MapQuest entered into another agreement under which MapQuest
was paid by Digital City to provide mapping and routing information and
services to Digital City.

   In early September 1999, Michael J. Mulligan, Chief Executive Officer of
MapQuest, met with Paul DeBenedictis, President of Digital City, at America
Online's offices to discuss the merits of a possible strategic relationship
between America Online and MapQuest, including among other things, a possible
combination of the two companies.

   On September 10, 1999, Mr. Mulligan, James W. Thomas, Chief Financial
Officer of MapQuest, and William Muenster, Senior Vice President of Development
and Production of MapQuest, met with Mr. DeBenedictis, Fred Singer, Senior Vice
President, Interactive Properties, of America Online, and Jim Davidson, Vice
President, Technology, of Digital City, at MapQuest's Denver offices to conduct
further discussions regarding a possible business combination of America Online
and MapQuest.

   On September 20, 1999, Mr. Mulligan, Mr. Thomas, Mr. Muenster and other
members of MapQuest's management met at MapQuest's offices with Mr.
DeBenedictis, Mr. Singer, Mr. Davidson, Ron Grant, Vice President, Business
Affairs, of America Online, and Steve Chien, Director, Business Development and
Strategy, of Digital City, to begin a due diligence investigation of MapQuest.

   On October 5, 1999, MapQuest and America Online entered into a
Confidentiality and Non-Disclosure Agreement in which the parties agreed to
keep confidential any information received in the course of conducting their
respective due diligence investigation and negotiating the proposed
transaction. On that day and again on October 20, 1999, Mr. Mulligan met with
Mr. DeBenedictis and Donn Davis, Chief Operating Officer, Interactive
Properties, of America Online, to continue discussions regarding a possible
business combination of America Online and MapQuest.

   From October 5, 1999 through the date of the execution of the merger
agreement, America Online and its financial and legal advisors conducted due
diligence on MapQuest, and MapQuest and its financial advisors periodically
conducted financial due diligence on America Online.

   On October 22, 1999, the MapQuest board conducted a conference call to
obtain a status report with respect to the negotiation process with America
Online. MapQuest's management was instructed by the board to continue
discussions with all interested parties about a potential business combination
transaction and to commence price range discussions with America Online. After
the board conference call, Mr. Mulligan had discussions with representatives
from Robertson Stephens regarding that firm's possible role as MapQuest's

                                       25

investment banker in a potential business combination. Robertson Stephens had
been the co-manager of MapQuest's initial public offering in May 1999 and had
subsequently been engaged by MapQuest to seek out strategic acquisition
opportunities for MapQuest.

   On October 26, 1999, Mr. Mulligan and Mr. Thomas conducted an exploratory
meeting with the chief executive officer of another company to discuss a
possible business combination with MapQuest. This meeting did not result in a
formal offer for a business combination.

   On October 27, 1999, the MapQuest board met in New York to discuss a
possible business combination with America Online. This meeting was also
attended by representatives of Mayer, Brown & Platt and Robertson Stephens. The
MapQuest board received a briefing by Robertson Stephens with respect to
financial and stock market information about America Online and other potential
merger parties. The MapQuest board instructed MapQuest management to continue
to investigate and identify, through Robertson Stephens, other possible
transactions and other potential proposals. The MapQuest board asked Robertson
Stephens to conduct further inquiries and contact additional third parties. At
that board meeting, the MapQuest board also authorized MapQuest management,
pending the results of Robertson Stephens' inquiries into other possible
transactions or proposals, to enter into a non-solicitation agreement with
America Online.

   On November 1, 1999, Mr. Mulligan, Daniel Nova, a director of MapQuest, and
representatives of Robertson Stephens met with David Colburn, President,
Business Affairs, Mr. Davis, Lynda Clarizio, Vice President, Business Affairs,
and Michael McGowan, Vice President and Associate General Counsel, of America
Online to discuss exchange ratios and other principal terms of a possible
business combination, and similar discussions continued telephonically through
November 5, 1999.

   On November 5, 1999, at the request of America Online, MapQuest signed a
non-solicitation agreement with America Online, in which MapQuest agreed not to
solicit or engage in any discussions or negotiations with any other third party
regarding a potential business combination or acquisition involving MapQuest
prior to November 18, 1999. At that time, MapQuest was satisfied that a
transaction with America Online would be in its stockholders' best interests
and determined to pursue a transaction exclusively with America Online for a
two week period.

   From November 5, 1999 through November 12, 1999, members of management of
America Online and MapQuest, along with their respective legal and financial
advisors, met in New York and telephonically to continue to conduct due
diligence and negotiate the terms of the proposed merger between MapQuest and
America Online and the related agreements. During that time, the parties
negotiated the principal terms of the agreements and other related documents,
including the exchange ratio, restrictions on MapQuest's ability to pursue
alternative transactions, representations and warranties, covenants,
termination provisions and conditions to the closing of the merger.

   On November 9, 1999 and on November 22, 1999, the MapQuest board met
telephonically to obtain an update on the status of the negotiation process
with America Online.

   From November 23, 1999 through December 3, 1999, America Online continued to
conduct due diligence with respect to MapQuest, including participating with
MapQuest in discussions with certain suppliers regarding their contractual
arrangements with MapQuest, and continued to negotiate the terms of the merger
agreement and related agreements.

   On December 15, 1999 and December 16, 1999, the MapQuest board met
telephonically to obtain an update with respect to the status of the
negotiation process with America Online and to discuss possible transactions
with other third parties.

   From December 15, 1999 through December 21, 1999, members of management of
America Online and MapQuest, along with their respective legal and financial
advisors, resumed negotiation of the terms of the

                                       26
<PAGE>

proposed merger and the related agreements. During that time, the parties
continued to negotiate the principal terms of the agreements and other related
documents, including the exchange ratio, restrictions on MapQuest's ability to
pursue alternative transactions, representations and warranties, covenants,
termination provisions and conditions to the closing of the merger.

   On the afternoon of December 21, 1999, the MapQuest board of directors held
a telephonic meeting to consider the terms of the proposed transaction with
America Online. At this meeting, members of management of MapQuest discussed
the results of the negotiations with America Online and the terms of the
proposed merger, including status and timing of the transaction, pricing and
valuation of the proposed merger, strategic and business opportunities with
America Online, pros and cons of the merger, market changes since MapQuest's
initial public offering in May of 1999 and a review of MapQuest's financial
performance and prospects; representatives of Robertson Stephens reviewed and
discussed the alternative transactions investigated by Robertson Stephens at
the direction of the board of directors, presented an analysis of the financial
terms of the proposed merger and delivered its oral opinion, subsequently
confirmed in writing as of December 21, 1999, as to the fairness of the
exchange ratio, from a financial point of view as of such date, to the holders
of MapQuest common stock; and representatives of Mayer, Brown & Platt outlined
the terms of the proposed merger agreement, including restrictions on
MapQuest's ability to pursue alternative transactions, closing conditions and
termination provisions, the stock option agreement, the stockholders agreement,
the distribution agreement and the other related documents. Following these
presentations and the related discussions by the MapQuest board, the entire
MapQuest board unanimously concluded that the merger was in the best interests
of MapQuest and MapQuest's stockholders, declared the merger advisable,
unanimously approved the proposed terms of the merger and the merger agreement
in substantially the form presented, and authorized MapQuest's officers to
complete the negotiation and execution of the merger agreement and resolved to
recommend that MapQuest stockholders vote to adopt the merger agreement.

   Following the meeting of the MapQuest board of directors, the board of
directors of America Online held a meeting to review and consider the merger,
the merger agreement and the related transactions. Management of America Online
made a presentation to its board concerning the business, financial condition
and prospects of MapQuest and the terms of the merger agreement, the stock
option agreement, the stockholders agreement, the distribution agreement and
the other agreements to be executed in connection with the merger. Management
of America Online discussed with its board the course of negotiations with
MapQuest and its advisors and the due diligence investigation of MapQuest that
had been performed. Following discussion among America Online's board of
directors and America Online management concerning the transaction, the board
of directors of America Online unanimously approved the merger, the merger
agreement and all of the related agreements.

   In the evening of December 21, 1999, MapQuest and America Online entered
into the merger agreement and the stock option agreement and the MapQuest
stockholders identified on page 54 under the heading "Stockholders Agreement"
entered into the stockholders agreement with America Online. In addition, each
of the members of the board of directors, the executive officers and certain
stockholders of MapQuest entered into an affiliate agreement with America
Online. On the morning of December 22, 1999, America Online and MapQuest issued
a joint press release announcing the merger.

America Online's Reasons for the Merger

   America Online's board of directors believes that following the merger
America Online will have the potential to realize enhanced long-term operating
and financial results and an improved competitive position as a result of its
acquisition of MapQuest. America Online's board of directors considered
potential benefits of the merger that they believe will result from combining
MapQuest with America Online, including the following:

  .  enhancing the interactive experience for users across America Online's
     brands by adding maps and directions and new methods of customization to
     its online services and Web properties,

  .  enhancing the ability to create advertising and electronic commerce
     opportunities targeted at the fast-growing business of local interactive
     services,


                                       27
<PAGE>

  .  advancing America Online's "AOL Anywhere" strategy by providing location
     information, maps and directions on a range of devices such as handheld
     computers, cellular phones and other non-PC devices,

  .  increasing the reach of America Online's local interactive business, as
     well as expanding the reach of MapQuest to new customers,

  .  providing new cross-promotional and branding opportunities, and

  .  enabling America Online to expand the provision of interactive mapping
     and related functionalities both locally in the United States and
     internationally.

   America Online's board of directors also considered the terms of the merger
agreement, including the possible effects of the provisions regarding
termination fees, and the stock option agreement, stockholders agreement and
other related agreements. In addition, America Online's board of directors
noted that the merger is expected to be a tax-free transaction and accounted
for as a pooling-of-interests, such that no goodwill is expected to be created
on the books of America Online as a result of the merger.

   The foregoing discussion is not exhaustive of all of the factors considered
by America Online's board of directors. Each member of America Online's board
may have considered different factors, and America Online's board did not
quantify or otherwise assign relative weights to factors considered.

MapQuest's Reasons for the Merger

   MapQuest's board of directors considered potential benefits of the merger
that they believe may result from merging with America Online, including the
following:

  .  combining with America Online will allow MapQuest to expand its core
     online mapping and destination information business through the combined
     company's widespread brand recognition and expanded audience base,

  .  the merger will enhance the opportunity for the realization of
     MapQuest's strategic objectives of building brand awareness through
     access to America Online's expanded audience base,

  .  combining with America Online will increase the advertising and business
     and consumer customer relationships available to grow MapQuest's
     products and services,

  .  combining with America Online will substantially contribute to
     MapQuest's strategy of international expansion,

  .  combining with America Online will provide MapQuest with the opportunity
     to expand research and development targeted at its online and wireless
     products and services, enabling MapQuest to expand and enhance the
     MapQuest service,

  .  MapQuest's stockholders will have the opportunity to participate in the
     potential for growth of the combined company after the merger, and

  .  the America Online common stock to be received by MapQuest stockholders
     has historically enjoyed a great deal of liquidity and has been the
     subject of a large volume of published investment research and analysis.

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

  .  historical information concerning America Online's and MapQuest's
     respective businesses, financial performance and conditions, operations,
     technologies, managements and competitive positions, including public
     reports concerning results of operations during the most recent fiscal
     year and fiscal quarter for each company filed with the Securities and
     Exchange Commission,

                                       28
<PAGE>


  .  MapQuest management's view as to the financial condition, results of
     operations and businesses of America Online and MapQuest, before and
     after giving effect to the merger, based on management's due diligence,
     including a review of publicly available earnings estimates for both
     companies,

  .  current financial market conditions and historical market prices,
     volatility and trading information with respect to America Online common
     stock and MapQuest common stock,

  .  the consideration to be received by MapQuest stockholders in the merger
     and an analysis of the market value of the America Online common stock
     to be issued in exchange for each share of MapQuest common stock in
     light of comparable merger transactions,

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

  .  MapQuest management's review of MapQuest's financial performance and
     prospects as an independent company,

  .  MapQuest management's view as to the potential for other third parties
     to enter into strategic relationships with or to acquire MapQuest,

  .  Robertson Stephens' reports on its due diligence inquiries of potential
     third-party acquirors,

  .  detailed financial analysis and other information with respect to the
     companies presented by Robertson Stephens to the board and Robertson
     Stephens' opinion that, as of the date of its opinion and subject to the
     considerations described in its opinion, the exchange ratio pursuant to
     the merger agreement was fair, from a financial point of view, to the
     MapQuest stockholders, which opinion is attached as Annex D, and

  .  reports from management and MapQuest's advisors as to the results of
     their due diligence investigation of America Online.

   MapQuest's board of directors also considered the terms of the merger
agreement regarding MapQuest's rights and limits on its ability to consider and
negotiate other strategic transaction proposals, as well as the possible
effects of the provisions regarding termination fees and the stock option
agreement. In addition, MapQuest's board of directors noted that the merger is
expected to be a tax-free transaction, except as to cash paid for fractional
shares, and accounted for as a pooling-of-interests, such that no goodwill is
expected to be created on the books of the combined company as a result of the
merger. Furthermore, MapQuest's board of directors also considered various
alternatives to the merger, including combining with companies other than
America Online or remaining as an independent company.

   MapQuest's board of directors also identified and considered a variety of
potentially negative factors in its deliberations concerning the merger,
including, but not limited to:

  .  the risk that the potential benefits sought in the merger might not be
     fully realized,

  .  the possibility that the merger might not be consummated and the effect
     of public announcement of the merger on:

    .  MapQuest's sales and operating results,

    .  MapQuest's ability to attract and retain key management, marketing
       and technical personnel, and

    .  the progress of MapQuest's current development and marketing
       projects,

  .  the risk that some of MapQuest's portal customers may view America
     Online as their competitor,

  .  the fact that unvested options granted to MapQuest officers and
     employees under MapQuest's 1995 Stock Option Plan would vest upon the
     announcement of the merger,

  .  deal protection requirements and limitations on MapQuest and its
     directors and certain stockholders relating to their ability to pursue
     alternative transactions,

                                       29
<PAGE>

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

  .  the risk that despite the efforts of the combined company, key technical
     and management personnel might not remain employed,

  .  the terms and ramifications of the option agreement,

  .  the other risks described under "Risk Factors" beginning on page 19.

   After due consideration and discussion, MapQuest's board of directors
decided that these risks were outweighed by the potential benefits of the
merger.

   The foregoing discussion is not exhaustive of all of the factors considered
by MapQuest's board of directors. Each member of MapQuest's board may have
considered different factors, and MapQuest's board did not quantify or
otherwise assign relative weights to factors considered.

Recommendation of MapQuest's Board of Directors

   After careful consideration, MapQuest's board of directors unanimously
determined the merger to be fair to you and in your best interest, and declared
the merger advisable. MapQuest's board of directors unanimously approved the
merger agreement and unanimously recommends your adoption of the merger
agreement.

   In considering the recommendation of the MapQuest board of directors with
respect to the merger agreement, you should be aware that certain directors and
officers of MapQuest have certain interests in the merger that are different
from, or are in addition to, the interests of MapQuest stockholders generally.
Please see the section entitled "Interests of Certain MapQuest Directors and
Officers in the Merger" beginning on page 37 of this proxy
statement/prospectus.

Opinion of MapQuest's Financial Advisor

   MapQuest engaged Robertson Stephens to render an opinion as to the fairness
of the exchange ratio, from a financial point of view, to holders of shares of
MapQuest common stock other than America Online or any of its affiliates.

   On December 21, 1999, at a meeting of the MapQuest board held to evaluate
the proposed merger, Robertson Stephens delivered to the MapQuest board its
oral opinion, subsequently confirmed in writing as of December 21, 1999, that,
as of that date and based on the assumptions made, the matters considered and
the limitations on the review undertaken described in the opinion, the exchange
ratio was fair, from a financial point of view, to the holders of shares of
MapQuest common stock other than America Online or any of its affiliates. The
exchange ratio was determined through negotiations between the respective
managements of MapQuest and America Online. Although Robertson Stephens did
assist the management of MapQuest in these negotiations, it was not asked to,
and did not, recommend to MapQuest any specific exchange ratio as the
appropriate exchange ratio for the merger. Robertson Stephens assisted
MapQuest's management in the negotiations leading to an agreement on principal
structural terms of the merger.

   The full text of the Robertson Stephens opinion, which sets forth, among
other things, assumptions made, matters considered and limitations on the
review undertaken, is attached as Annex D and is incorporated in this proxy
statement/prospectus by reference. We urge MapQuest stockholders to read the
Robertson Stephens opinion in its entirety. The Robertson Stephens opinion was
prepared for the benefit and use of the MapQuest board in connection with its
evaluation of the merger and does not constitute a recommendation to
stockholders of MapQuest as to how they should vote, or take any other action,
with respect to the merger.


                                       30
<PAGE>

   The Robertson Stephens opinion does not address:

  .  the relative merits of the merger and the other business strategies that
     the MapQuest board has considered or may be considering; or

  .  the underlying business decision of the MapQuest board to proceed with
     the merger.

   The summary of the Robertson Stephens opinion set forth in this proxy
statement/prospectus is qualified in its entirety by reference to the full text
of the Robertson Stephens opinion.

   In connection with the preparation of the Robertson Stephens opinion,
Robertson Stephens, among other things:

     business and financial information of MapQuest and America Online,
     respectively,

     analysts relating to MapQuest,

     relating to America Online,

  .  held discussions with the respective managements of MapQuest and America
     Online concerning the businesses, past and current operations and
     financial condition of both MapQuest and America Online and also the
     future prospects of the combined businesses, including discussions with
     the managements of MapQuest and America Online concerning their views
     regarding the strategic rationale for the merger,

     the extent publicly available, of other transactions that it deemed

Stephens assumed and relied upon the accuracy and completeness of all of the
financial and other information provided to it, including information furnished
to it orally or otherwise discussed with it by the managements of MapQuest and
America Online, or publicly available and neither attempted to verify, nor
assumed responsibility for verifying, any of such information. Robertson
Stephens relied upon the assurances of MapQuest's management that they were not
aware of any facts that would make such information inaccurate or misleading.
Furthermore, Robertson Stephens did not obtain or make, or assume any
responsibility for obtaining or making, any independent evaluation or appraisal
of the properties, assets or liabilities, contingent or otherwise, of MapQuest
or America Online, nor was Robertson Stephens furnished with any such
evaluation or appraisal.

                                       31
<PAGE>

   Robertson Stephens reviewed publicly available financial analysts'
estimates, and the assumptions and bases therefor, concerning each of MapQuest
and America Online, and Robertson Stephens assumed that such forecasts and
projections:

  .  had been reasonably prepared in good faith on the basis of reasonable
     assumptions, and

  .  reflected the best available estimates and judgments as to the future
     financial condition and performance of MapQuest and America Online,
     respectively.

   In this regard, Robertson Stephens noted that each of MapQuest and America
Online face exposure to the Year 2000 problem. Robertson Stephens did not
undertake any independent analysis to evaluate the reliability or accuracy of
the assumptions made with respect to the potential effect that the Year 2000
problem might have on their respective forecasts.

   In addition, Robertson Stephens assumed that:

  .  the merger will be consummated upon the terms set forth in the merger
     agreement without material alteration thereof, including, among other
     things, that the merger will be accounted for as a "pooling-of-
     interests" business combination in accordance with U.S. generally
     accepted accounting principles ("U.S. GAAP"),

  .  the merger will be treated as a tax-free reorganization pursuant to the
     Internal Revenue Code of 1986, as amended, and

  .  the historical financial statements of each of MapQuest and America
     Online reviewed by it had been prepared and fairly presented in
     accordance with U.S. GAAP consistently applied.

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

   Although developments following the date of the Robertson Stephens opinion
may affect the opinion, Robertson Stephens assumed no obligation to update,
revise or reaffirm its opinion. The Robertson Stephens opinion is necessarily
based upon market, economic and other conditions as in effect on, and
information made available to Robertson Stephens as of December 21, 1999. It
should be understood that subsequent developments may affect the conclusion
expressed in the Robertson Stephens opinion and that Robertson Stephens
disclaims any undertaking or obligation to advise any person of any change in
any matter affecting the opinion which may come or be brought to its attention
after the date of the opinion. The Robertson Stephens opinion is limited to the
fairness, from a financial point of view and as of the date thereof, of the
exchange ratio to holders of shares of MapQuest common stock other than America
Online or any of its affiliates. Robertson Stephens does not express any
opinion as to:

  .  the value of any employee agreement or other arrangement entered into in
     connection with the merger,

  .  any tax or other consequences that might result from the merger, or

  .  what the value of America Online common stock will be when issued to
     MapQuest's stockholders pursuant to the merger or the price at which the
     shares of America Online common stock that are issued pursuant to the
     merger may be traded in the future.

   The following is a summary of the material financial analyses performed by
Robertson Stephens in connection with rendering its opinion. The summary of the
financial analyses is not a complete description of all of the analyses
performed by Robertson Stephens. Certain of the information in this section is
presented in tabular form. In order to better understand the financial analyses
performed by Robertson Stephens, these tables must be read together with the
text of each summary. The Robertson Stephens opinion is based upon the totality

   Multiples compared by Robertson Stephens included total capitalization to
estimated revenues for calendar years 1999 and 2000. All multiples were based
on closing stock prices as of December 17, 1999.

   Using the ranges of multiples set forth in the table below that Robertson
Stephens derived from multiples for the comparable companies, the following
MapQuest equity values and exchange ratios are implied based upon MapQuest's
1999 and 2000 estimated Internet revenues:

  Precedent Acquisition Analysis

   Using publicly available information, Robertson Stephens analyzed the
consideration offered, the premiums paid and the implied transaction value
multiples paid or proposed to be paid in selected acquisition transactions in
the Internet content and service industry, including:

  .  Isocor/Critical Path (October 21, 1999)

  .  Flycast Communications/CMGI (September 30, 1999)

  .  Earthlink Network/MindSpring Enterprises (September 23, 1999)

  .  Excite/AtHome (January 19, 1999)

  .  Starfish Software/Motorola (July 14, 1998)

   In analyzing these "precedent transactions", Robertson Stephens compared,
among other things, the total consideration in such transactions as a multiple
of estimated revenues for calendar years 1999 and 2000. All multiples for the
precedent transactions were based on public information available at the time
of the announcement. Based on this information and other publicly available
information, the following table illustrates the implied MapQuest equity
valuations and exchange ratios derived from applying a range of multiples that
Robertson Stephens derived from the precedent transactions to MapQuest's 1999
and 2000 estimated Internet revenues:

   2000 Internet revenues... 10.0x-25.0x 0.114x-0.263x  $391.3-$906.8 million
</TABLE>

   No company, business or transaction compared in the comparable companies
analysis or precedent transaction analysis is identical to MapQuest or America
Online. Accordingly, an analysis of the results of the

                                       34
<PAGE>

foregoing is not entirely mathematical; rather it involves complex
considerations and judgments concerning differences in financial and operating
characteristics and other factors that could affect the acquisition, public
trading and other values of the comparable companies, precedent transactions or
the business segment, company or transactions to which they are being compared.

   Based upon the foregoing equity value and exchange ratio ranges implied by
the comparable companies analysis and the precedent transaction analysis,
Robertson Stephens derived an average implied equity valuation range for
MapQuest's Internet business of $687.0 million-$1,194.7 million and an average
implied exchange ratio range for MapQuest's Internet business of 0.200x-0.347x.

  Digital Mapping Services Valuation

   Robertson Stephens also applied multiples to the digital mapping services
revenues of MapQuest. Using the ranges of multiples set forth in the table
below, the following MapQuest equity values and exchange ratios are implied for
MapQuest's DMS business:

<TABLE>
<CAPTION>
                                              Implied

   2000 DMS revenues.......   2.5x-3.5x    0.015x-0.020x   $50.0-$70.0 million

   Robertson Stephens added the above equity value range and exchange ratio
range implied by the digital mapping services valuation to the average equity
value range and exchange ratio range implied for MapQuest's Internet business
pursuant to the comparable companies analysis and precedent acquisition
analyses, as summarized above. The resulting average implied MapQuest equity
value range and exchange ratio range are set forth in the table below:

  Premiums Paid Analysis

   Robertson Stephens also considered the premiums paid in the precedent
transactions over the target's closing share price the day before the
transaction was announced and 30 days prior to the announcement. Based on this
information and other publicly available information, the following table
illustrates the implied MapQuest equity values and exchange ratios derived from
applying a range of premiums that Robertson Stephens derived from the precedent
transactions:

   Robertson Stephens combined the above equity value range and exchange ratio
range implied by the premiums paid analysis to the average equity value range

  Relative Contribution Analysis

   Based upon financial analyst estimates for MapQuest and America Online,
Robertson Stephens analyzed the respective contributions of the Internet
revenues of MapQuest and America Online to the estimated Internet revenues of
the combined company for fiscal years 2000 and 2001. The actual revenues
achieved may vary from the estimated revenues and the variations may be
material.

  Pro Forma Analysis

   Robertson Stephens analyzed certain pro forma effects resulting from the
merger, including, among other things, the impact of the merger on the
projected revenues per share and earnings per share of the combined company for
fiscal years 2000 and 2001. The following table summarizes the results of such
analysis:

<TABLE>
      <S>                                                               <C>

      Fiscal year 2001 estimated revenue per share accretion...........  0.5%
      Fiscal year 2001 estimated earnings per share
       accretion/(dilution)............................................ (0.6)%
</TABLE>

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

  Other Factors and Comparative Analyses

   In rendering its opinion, Robertson Stephens considered certain other
factors and conducted certain other comparative analyses, including, among
other things a review of:

  .  the history of trading prices and volume for MapQuest common stock for
     the period from May 4, 1999 to December 17, 1999; and

  .  the history of trading prices and volume for America Online common stock
     for the period from December 17, 1998 to December 17, 1999; and

  .  selected published analysts' reports on MapQuest and America Online.

   While the foregoing summary describes certain analyses and factors that
Robertson Stephens deemed material in its presentation to the MapQuest board,
it is not a comprehensive description of all analyses and factors considered by
Robertson Stephens. The preparation of a fairness opinion is a complex process
that involves various determinations as to the most appropriate and relevant
methods of financial analysis and the application of these methods to the
particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description. Robertson Stephens believes that its
analyses must be considered as a whole and that selecting portions of its
analyses and of the factors considered by it, without considering all analyses
and factors, would create an incomplete view of the evaluation process
underlying the Robertson Stephens opinion. Several analytical methodologies
were employed and no one method of analysis should be regarded as critical to
the overall conclusion reached by Robertson Stephens. Each analytical technique
has inherent strengths and weaknesses, and the nature of the available
information may further affect the value of particular techniques. The
conclusions reached by Robertson Stephens are based on all analyses and factors
taken as a whole and also on application of Robertson Stephens' own experience
and judgment. Such conclusions may involve significant elements of subjective
judgment and qualitative analysis. Robertson

                                       36
<PAGE>

Stephens therefore gives no opinion as to the value or merit standing alone of
any one or more parts of the analysis that it performed. In performing its
analyses, Robertson Stephens considered general economic, market and financial
conditions and other matters, many of which are beyond the control of MapQuest
and America Online. The analyses performed by Robertson Stephens are not
necessarily indicative of actual values or future results, which may be
significantly more or less favorable than those suggested by such analyses.
Accordingly, analyses relating to the value of a business do not purport to be
appraisals or to reflect the prices at which the business actually may be
purchased. Furthermore, no opinion is being expressed as to the prices at which
shares of MapQuest common stock or America Online common stock may be traded at
any future time.

   The engagement letter between Robertson Stephens and MapQuest provides that
Robertson Stephens is entitled to receive a fee for its services, a substantial
portion of which is contingent upon the consummation of the merger. MapQuest
has also agreed to reimburse Robertson Stephens for certain of its out-of-
pocket expenses, including legal fees, and to indemnify and hold harmless
Robertson Stephens and its affiliates and any director, employee or agent of
Robertson Stephens or any of its affiliates, or any person controlling
Robertson Stephens or its affiliates for certain losses, claims, damages,
expenses and liabilities relating to or arising out of services provided by
Robertson Stephens as financial advisor to MapQuest. The terms of the fee
arrangement with Robertson Stephens, which MapQuest and Robertson Stephens
believe are customary in transactions of this nature, were negotiated at arm's
length between MapQuest and Robertson Stephens, and the MapQuest board was
aware of such fee arrangements, including the fact that a significant portion
of the fees payable to Robertson Stephens is contingent upon completion of the
merger. In the past, Robertson Stephens has provided certain investment banking
services to MapQuest for which it has been paid fees, including acting as lead
manager of MapQuest's initial public offering. In the ordinary course of its
business, Robertson Stephens may trade in MapQuest's securities and America
Online's securities for its own account and the account of its customers and,
accordingly, may at any time hold a long or short position in MapQuest's
securities or America Online's securities.

   Robertson Stephens was retained by MapQuest based on Robertson Stephens'
experience as a financial advisor in connection with mergers and acquisitions
and in securities valuations generally, as well as Robertson Stephens'
investment banking relationship and familiarity with MapQuest.

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

Interests of Certain MapQuest Directors and Officers in the Merger

   When considering the recommendation of MapQuest's board of directors, you
should be aware that the MapQuest directors and the executive officers
identified below have interests in the merger that are different from, or are
in addition to, yours.

   In particular, the three executive officers of MapQuest, Michael Mulligan,
James Thomas and William Muenster, have signed letters containing offers of
employment from America Online that will become effective upon the completion
of the merger. Eight other members of MapQuest's management have also signed
similar letters containing offers of employment. These offer letters and the
offer letters for the three officers, in the aggregate, contain a commitment to
grant to these officers options to purchase a total of 670,000 shares of
America Online common stock.

   In addition, all unvested stock options granted under MapQuest's 1995 Stock
Option Plan to all executive officers and employees of MapQuest vested upon the
announcement of the merger in accordance with the existing plan provisions. The
number of shares of MapQuest common stock subject to unvested options held by
MapQuest's executive officers that vested upon announcement of the merger
totaled 972,001 on December 21, 1999. Unvested stock options outstanding under
MapQuest's 1999 Stock Plan do not vest upon the announcement of the merger.


                                       37
<PAGE>


   In addition, Michael Mulligan and James Thomas, in their capacity as
stockholders of MapQuest, have each signed the stockholders agreement,
described under "Stockholders Agreement" on page 54, and have agreed to vote
their shares in favor of adopting the merger agreement.

   The continuation of indemnification arrangements for current directors of
MapQuest following completion of the merger, may influence these directors in
making their recommendation that you vote in favor of the adoption of the
merger agreement.

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 the adoption of the merger agreement
by the stockholders of MapQuest. The merger will become effective upon the
filing of a certificate of merger with the Secretary of State of the State of
Delaware.

   We are working towards completing the merger as quickly as possible. We hope
to complete the merger in June 2000.

Structure of the Merger and Conversion of MapQuest Common Stock

   In accordance with the merger agreement and Delaware law, MQ Acquisition,
Inc., a newly formed and wholly owned subsidiary of America Online, will be
merged with and into MapQuest. As a result of the merger, the separate
corporate existence of MQ Acquisition will cease and MapQuest will survive the
merger as a wholly owned subsidiary of America Online.

   Upon completion of the merger, each outstanding share of MapQuest common
stock, other than shares held by us and our subsidiaries, will be converted
into the right to receive 0.31558 of a share of America Online common stock.

   The number of shares of America Online common stock issuable in the merger
will be proportionately adjusted for any future stock split, stock dividend or
similar event with respect to America Online common stock effected between the
date of the merger agreement and the completion of the merger.

   No certificate or scrip representing fractional shares of America Online
common stock will be issued in connection with the merger. Instead you will
receive cash, without interest, in lieu of a fraction of a share of America
Online common stock. Specifically, the exchange agent in the merger will sell a
number of shares of America Online common stock equal to the aggregate number
of fractional shares that would otherwise be issuable in the merger and will
remit to you an amount equal to your pro rata portion of the proceeds of these
sales.

Exchange of MapQuest Stock Certificates for America Online Stock Certificates

   When the merger is completed, the exchange agent will mail to you an
executed letter of transmittal and instructions for use in surrendering your
MapQuest stock certificates in exchange for America Online stock certificates.
When you deliver your MapQuest stock certificates to the exchange agent along
with a properly executed letter of transmittal and any other required
documents, your MapQuest stock certificates will be canceled and you will
receive America Online stock certificates representing the number of full
shares of America Online common stock to which you are entitled under the
merger agreement. You will receive payment in cash, without interest, in lieu
of any fractional shares of America Online common stock which would have been
otherwise issuable to you as a result of the merger.

   You should not submit your MapQuest stock certificates for exchange unless,
and until, you receive the transmittal instructions and a form of letter of
transmittal from the exchange agent.

                                       38
<PAGE>

   You are not entitled to receive any dividends or other distributions, if any
are declared on America Online common stock, until the merger is completed and
you have surrendered your MapQuest stock certificates in exchange for America
Online stock certificates.

   If there is any dividend or other distribution on America Online common
stock with a record date after the merger and a payment date prior to the date
you surrender your MapQuest stock certificates in exchange for America Online
stock certificates, you will receive such dividend or distribution with respect
to the whole shares of America Online common stock issued to you promptly after
they are issued. If there is any dividend or other distribution on America
Online common stock with a record date after the merger and a payment date
after the date you surrender your MapQuest stock certificates in exchange for
America Online stock certificates, you will receive such dividend or
distribution with respect to the whole shares of America Online common stock
issued to you promptly after the payment date.

   America Online will issue an America Online stock certificate or a check in
lieu of a fractional share in a name other than the name in which a surrendered
MapQuest stock certificate is registered only if you present the exchange agent
with all documents required to show and effect the unrecorded transfer of
ownership and show that you paid any applicable stock transfer taxes.

Material United States Federal Income Tax Consequences of the Merger

   The following summary discusses the material United States federal income
tax consequences of the merger, assuming that you hold your shares of MapQuest
common stock as capital assets. The following discussion is based on and
subject to the Internal Revenue Code of 1986, as amended, its legislative
history, applicable Treasury regulations, administrative rulings and court
decisions currently in effect, all of which are subject to change at any time,
possibly with retroactive effect, and assumptions, limitations, representations
and covenants, including those contained in certificates of officers of America
Online, MQ Acquisition and MapQuest. This discussion does not address all
aspects of United States federal income taxation that may be important to you
in light of your particular circumstances, or if you are subject to special
rules, such as rules relating to:

  .  stockholders who are not citizens or residents of the United States,

  .  financial institutions,

  .  tax-exempt organizations,

  .  insurance companies,

  .  dealers in securities,

  .  stockholders who acquired their shares of MapQuest common stock by
     exercising employee stock options or rights or otherwise as
     compensation, and

  .  stockholders who hold their shares of MapQuest common stock as part of a
     hedge, straddle or conversion transaction.

   Simpson Thacher & Bartlett, counsel to America Online, has delivered its
opinion to America Online and Mayer, Brown & Platt, counsel to MapQuest, has
delivered its opinion to MapQuest, to the effect that, for federal income tax
purposes:

  .  the merger will be treated as a reorganization within the meaning of
     Section 368(a) of the Internal Revenue Code,

  .  no gain or loss will be recognized by America Online, MapQuest and MQ
     Acquisition as a result of the merger,

                                       39
<PAGE>

  .  no gain or loss will be recognized by holders of MapQuest common stock
     who exchange all of their MapQuest common stock solely for America
     Online common stock in the merger, except that gain or loss may be
     recognized by such holders with respect to cash received in lieu of a
     fractional share interest in America Online common stock,

  .  the aggregate adjusted basis of the America Online common stock received
     by holders of MapQuest common stock in the merger (treating fractional
     share interests in America Online common stock as having been issued to
     such holders in the merger and then redeemed for cash) will be the same
     as such holders' aggregate tax basis in the MapQuest common stock
     surrendered in the merger, and

  .  the holding period of the America Online common stock that a holder of
     MapQuest common stock receives in the merger will include the period
     during which such holder held the MapQuest common stock surrendered in
     the merger.

   The Simpson Thacher & Bartlett opinion and the Mayer, Brown & Platt opinion
are attached hereto as Exhibits 8.1 and 8.2, respectively. These opinions (1)
will be based on facts, representations and assumptions set forth or referred
to in the closing tax opinions that are consistent with the facts existing at
the time that the merger occurs, (2) may rely on representations and covenants
including those contained in the merger agreement and certificates of officers
of America Online, MapQuest, MQ Acquisition and others, reasonably satisfactory
in form and substance to the counsel issuing such opinions, that, if incorrect
in certain material respects could jeopardize the conclusions reached by
counsel issuing these opinions and (3) to the extent they address consequences
to holders of MapQuest common stock, may not be fully applicable to
stockholders subject to special rules as listed above. The closing tax opinions
are not binding on the IRS or the courts, and we do not intend to request a
ruling from the IRS with respect to the merger. Accordingly, there can be no
assurance that the IRS will not challenge the conclusions set forth in the
closing tax opinions or that a court will not sustain such a challenge.

 Cash Instead of Fractional Shares

   If you receive in the merger cash instead of a fractional share interest in
America Online common stock and, immediately after the merger, (1) you hold a
minimal interest in America Online, (2) you exercise no control over America
Online and (3) as a result of the receipt of this cash payment and after giving
effect to certain constructive ownership rules, you experience an actual
reduction in your interest in America Online, then you will recognize gain or
loss for United States federal income tax purposes with respect to the cash
received measured by the difference between the amount of cash you receive and
the portion of the tax basis of your shares of MapQuest common stock allocable
to the fractional share interest. This gain or loss will be capital gain or
loss and will be long-term capital gain or loss if your shares of MapQuest
common stock have been held for more than one year at the time the merger is
completed. If the requirements set forth in (1) through (3) above are not met,
the cash payment will be taxable to you as a dividend.

 Backup Withholding

   Certain non-corporate MapQuest stockholders may be subject to backup
withholding at a 31% rate on cash payments received instead of fractional
shares of America Online common stock. Backup withholding will not apply,
however, to a MapQuest stockholder who:

  .  furnishes a correct taxpayer identification number and certifies that
     he, she or it is not subject to backup withholding on the substitute
     Form W-9 or successor form included in the letter of transmittal to be
     delivered to MapQuest stockholders following the date of completion of
     the merger,

  .  provides a certification of foreign status on Form W-8 or successor
     form, or

  .  is otherwise exempt from backup withholding.

                                       40

   This discussion does not address tax consequences which may vary with, or
are contingent on, your individual circumstances. Moreover, this discussion
does not address any non-income tax or any foreign, state or local tax
consequences of the merger. Accordingly, you are strongly urged to consult with
your tax advisor to determine the particular United States federal, state,
local or foreign income or other tax consequences to you of the merger.

Accounting Treatment of the Merger

   We intend to account for the merger as a pooling-of-interests business
combination. It is a condition to the completion of the merger that America
Online be advised in writing by Ernst & Young LLP that they concur with America
Online's conclusion that the transactions contemplated by the merger agreement
can properly be accounted for as a pooling-of-interests business combination,
although this condition may be waived by America Online. Under the pooling-of-
interests method of accounting, each of our historical recorded assets and
liabilities will be carried forward to the combined company at their recorded
amounts. America Online currently does not intend to waive the condition
relating to the receipt of such advice from Ernst & Young LLP.

Regulatory Filings and Approvals Required to Complete the Merger

   The merger is subject to the requirements of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, which prevents specified transactions
from being completed until required information and materials are furnished to
the Antitrust Division of the Department of Justice and the Federal Trade
Commission and certain waiting periods terminate or expire. We have already
filed the required information and materials with the Department of Justice and
the Federal Trade Commission and the applicable waiting period expired on
February 27, 2000. The requirements of Hart-Scott-Rodino will be satisfied if
the merger is completed within one year from the termination of the waiting
period.

   The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the merger on antitrust grounds, either before or
after expiration of the waiting period. Accordingly, at any time before or
after the completion of the merger, either the Antitrust Division of the
Department of Justice or the Federal Trade Commission could take action under
the antitrust laws as it deems necessary or desirable in the public interest,
or other persons could take action under the antitrust laws, including seeking
to enjoin the merger. Additionally, at any time before or after the completion
of the merger, notwithstanding that the applicable waiting period expired or
was terminated, any state could take action under the antitrust laws as it
deems necessary or desirable in the public interest. There can be no assurance
that a challenge to the merger will not be made or that, if a challenge is
made, we will prevail.

   In addition, we have made the required filing in connection with the merger
with regulatory authorities in Germany. The German regulatory authorities
approved the merger on May 5, 2000.

   Neither of us is aware of any other material governmental or regulatory
approval required for completion of the merger, other than compliance with the
applicable corporate law of Delaware.

Restrictions on Sales of Shares by Affiliates of MapQuest and America Online

   The shares of America Online common stock to be issued in connection with
the merger will be registered under the Securities Act of 1933, as amended, and
will be freely transferable under the Securities Act, except for shares of
America Online common stock issued to any person who is deemed to be an
"affiliate" of either of us at the time of the special meeting. Persons who may
be deemed to be affiliates include individuals or entities that control, are
controlled by, or are under the common control of either of us and may include
some of our officers and directors, as well as our principal stockholders.

                                       41
<PAGE>

   Affiliates may not sell their shares of America Online common stock acquired
in connection with the merger except pursuant to:

  .  an effective registration statement under the Securities Act covering
     the resale of those shares,

  .  an exemption under paragraph (d) of Rule 145 under the Securities Act,
     or

  .  any other applicable exemption under the Securities Act.

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

Listing on the New York Stock Exchange of America Online Common Stock to be
Issued in the Merger

   America Online will use reasonable best efforts to cause the shares of
America Online common stock to be issued in connection with the merger to be
approved for listing on the New York Stock Exchange, subject to official notice
of issuance, before the completion of the merger.

Dissenters' and Appraisal Rights

   You are not entitled to exercise dissenter's or appraisal rights as a result
of the merger or to demand payment for your shares under Delaware law.

Delisting and Deregistration of MapQuest Common Stock After the Merger

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

Operations After the Merger

   Following the merger, MapQuest will continue its operations as a wholly
owned subsidiary of America Online. The membership of the America Online board
of directors will remain unchanged as a result of the merger. Eleven members of
the management of MapQuest, including Michael Mulligan, James Thomas and
William Muenster, who are the three executive officers of MapQuest, have
entered into letters of offers of employment with America Online which become
effective upon the closing of the merger. The stockholders of MapQuest will
become stockholders of America Online, and their rights as stockholders will be
governed by the America Online Restated Certificate of Incorporation, the
America Online Restated By-laws and the laws of the State of Delaware. See
"Comparison of Rights of Holders of MapQuest Common Stock and America Online
Common Stock" that begins on page 79.

<PAGE>

  .  any third party consents or waivers shall have been obtained for those

   A "Material Adverse Effect" is any fact, event, change, development,

    .  would materially impair or delay MapQuest's ability to perform its
       obligations under the merger agreement or under the option
       agreement, and

  .  when such term is used in relation to America Online or MQ Acquisition,

    .  is materially adverse to the business, financial condition, results

     to have a material adverse effect on the ability of America Online or MQ

  MapQuest's Conduct of Business Before Completion of the Merger

Online consents in writing, MapQuest and its subsidiaries will operate their

<PAGE>

   The agreements related to the conduct of MapQuest's business in the merger
agreement are complicated and not easily summarized. You are urged to carefully
read the article of the merger agreement entitled "Conduct of Business Pending
the Merger."

   Solicitation of Other Proposals Involving MapQuest

   MapQuest has certain obligations with respect to "Acquisition Proposals."

   An "Acquisition Proposal" is any inquiry, proposal or offer from any person
other than America Online, MQ Acquisition or any of their affiliates to
MapQuest and its subsidiaries that relates to any of the following:

  .  a merger, consolidation, recapitalization, liquidation or other direct
     or indirect business combination involving MapQuest or its subsidiaries,

  .  the issuance or acquisition of 20% or more (by voting power) of the
     outstanding capital stock or equity interests of MapQuest or its
     subsidiaries,

  .  any tender offer or exchange offer that, if completed, would result in
     any person or its affiliates beneficially owning 20% or more (by voting
     power) of the outstanding capital stock or other equity securities of
     MapQuest or its subsidiaries,

  .  the sale, lease, exchange, license or other disposition of any
     significant portion of the business or other assets of MapQuest or its
     subsidiaries, or

  .  any other transaction that could reasonably be expected to impede,
     interfere with, prevent or materially delay the merger or would
     reasonably be expected to diminish significantly the benefits to America
     Online or its affiliates of the transactions contemplated by the merger
     agreement.

   Until the merger is completed or the merger agreement is terminated,
MapQuest has agreed not to take any of the following actions and has agreed not
to permit any of its affiliates, subsidiaries or representatives to take any of
the following actions:

  .  solicit, facilitate, initiate, entertain or encourage any Acquisition
     Proposal, or take any action to solicit, facilitate, initiate, entertain
     or encourage any inquiries or the making of any proposal or offer that
     constitutes or may constitute an Acquisition Proposal, or

  .  participate or engage in discussions or negotiations with, or provide
     any information to, any person concerning an Acquisition Proposal or
     concerning matters that might reasonably be expected to result in an
     Acquisition Proposal.

MapQuest also agreed to terminate any discussions or negotiations with any
third parties that were taking place when the merger agreement was signed, if
the discussions or negotiations could reasonably be expected to result in an
Acquisition Proposal. Furthermore, MapQuest has agreed to provide America
Online with detailed information about any Acquisition Proposal it receives.

   However, MapQuest may participate in any discussions or negotiations that
are otherwise prohibited, or furnish otherwise prohibited information regarding
MapQuest pursuant to a confidentiality agreement which must be on terms no less
favorable to MapQuest than those in effect between MapQuest and America Online,
if all of the following occur:

  .  a third person has submitted an unsolicited, bona fide written
     Acquisition Proposal to MapQuest's board of directors,

  .  neither MapQuest nor any of its representatives has violated any of the
     restrictions outlined in the foregoing paragraph,


                                       46
<PAGE>

  .  MapQuest's board of directors determines by majority vote and in good
     faith, based upon consultation with outside counsel to MapQuest, that
     taking such action is required to satisfy the fiduciary duties of the
     board under applicable law, and

  .  MapQuest's board of directors provides America Online with prior written
     notice of its decision to participate in such discussions or to furnish
     such information.

   Additionally, MapQuest's board of directors must comply with certain
limitations. Except as explained below, MapQuest's board of directors and any
board committee may not take any of the following actions:

  .  approve or recommend, or propose to approve or recommend, any
     Acquisition Proposal other than the merger,

  .  withdraw or modify, or propose to withdraw or modify, in a manner
     adverse to America Online, the board's approval or recommendation of the
     merger and the related transactions and agreements,

  .  upon request by America Online, fail to reaffirm the board's approval or
     recommendation of the merger agreement or the merger within two days of
     America Online's request for reaffirmation,

  .  approve, enter or permit or cause MapQuest to enter into any letter of
     intent, agreement in principle, acquisition agreement or other similar
     agreement related to an Acquisition Proposal, or

  .  resolve or announce its intention to do any of the foregoing.

However, MapQuest's board of directors may take certain actions described above
if it receives a superior proposal. A "superior proposal" is any bona fide
proposal to effect a merger, consolidation or sale of all or substantially all
of the assets or capital stock of MapQuest which is on terms that MapQuest's
board of directors determines by a majority vote and in good faith that will
result in a transaction more favorable to MapQuest's stockholders than the
merger; such decision must be based on the written opinion of MapQuest's
financial advisors and on other relevant factors including the superior
proposal's conditions, the form of consideration, the timing of the closing of
the proposal, the likelihood of consummation and the ability of the person
making the proposal to finance the transaction and any required approvals. If
MapQuest does receive such a proposal, then its board of directors may take any
of the following actions:

  .  withdraw or modify, or propose to withdraw or modify, in a manner
     adverse to America Online, the MapQuest board's approval or
     recommendation of the merger and the related transactions and
     agreements,

  .  fail to reaffirm the board's approval or recommendation of the merger
     agreement or the merger within two business days from America Online's
     request for reaffirmation, or

  .  resolve or announce its intention to do either of the foregoing.

   Prior to MapQuest's board of directors engaging in any of the three above
actions, it must determine by a majority vote and in good faith, after
consultation with outside counsel, that taking such action is required to
satisfy the fiduciary duties of the board under applicable laws. Additionally,
MapQuest must furnish America Online two business days' prior notice of its
intent to take such actions.

  Additional Agreements Made in the Merger Agreement

   Both MapQuest and America Online have agreed to use their reasonable best
efforts to take, or cause to be taken and to do or cause to be done, all
actions to assist and cooperate with each other in performing all things
necessary, proper and advisable to complete the merger and the related
transactions. Accordingly, MapQuest and America Online have agreed to use their
reasonable best efforts to:

  .  as promptly as practicable, obtain all necessary approvals and make all
     necessary filings under applicable laws relating to the merger agreement
     and the option agreement,


                                       47
<PAGE>

  .  furnish all information required for any application or other filing
     required to be made by Delaware law or any other law or applicable
     regulation in connection with the merger and the related transactions,

  .  lift, rescind or mitigate the effects of any injunction or other order
     adversely affecting the ability of either America Online or MapQuest to
     complete the merger, subject to certain limitations specified in the
     merger agreement, and

  .  satisfy or cause to be satisfied all of the conditions that must be
     satisfied prior to the merger being completed as have been outlined in
     the preceding section of the proxy statement/prospectus, "Conditions to
     Completion of the Merger".

However, America Online and its affiliates are not obligated to take either of
the following actions:

  .  make proposals, execute or carry out agreements, or submit to orders,
     (1) providing for the sale or other disposition of any of the assets of
     America Online, its affiliates, or its subsidiaries, or (2) imposing or
     seeking to impose any limitation on the ability of America Online, its
     affiliates or its subsidiaries to acquire, hold or exercise full rights
     of ownership of MapQuest's common stock, or

  .  take any steps to avoid or eliminate any impediment asserted under any
     antitrust law if taking such steps, in America Online's reasonable
     judgment, might result in a limitation of the benefit that America
     Online expects to derive as a result of the merger or might adversely
     affect MapQuest, America Online or America Online's affiliates.

Additionally, America Online and MapQuest have agreed to cooperate with one
another in the following manners:
  .  the preparation of this proxy statement/prospectus and the registration
     statement of which it is a part,

  .  the preparation of any filing required under applicable antitrust laws,

  .  the identification and seeking of any filings and consents that are
     required to complete,

  .  the listing on the NYSE of the America Online common stock that will be
     issued as part of the merger, and

  .  the facilitating of the achievement of the benefits reasonably
     anticipated by the merger.

   Termination of the Merger Agreement

   The merger agreement may be terminated at any time prior to completion of
the merger, whether before or after adoption of the merger agreement by
MapQuest stockholders:

  .  by mutual consent of America Online and MapQuest,

  .  by America Online or MapQuest, if the merger is not completed before
     June 30, 2000 unless the merger is not completed solely due to the
     applicable waiting periods under antitrust laws not having expired or
     being terminated, in which case such date shall be extended to September
     30, 2000, except that the right to terminate the merger agreement is not
     available to any party whose willful failure to fulfill any material
     obligation under the merger agreement has been the cause of the failure
     to complete the merger on or before such date,

  .  by America Online or MapQuest, if there is any final and nonappealable
     order, decree or ruling of a court or governmental authority permanently
     prohibiting the completion of the merger,

  .  by America Online or MapQuest, if the merger agreement fails to receive
     the requisite vote for adoption by the stockholders of MapQuest at the
     special meeting,

  .  by America Online, if MapQuest's board of directors:


                                       48
<PAGE>


    .  approves or recommends, or proposes to approve or recommend, any
       Acquisition Proposal other than the merger (see the definition of
       Acquisition Proposal on page 46 of this proxy statement/prospectus),

    .  fails to present and recommend approval and adoption of the merger
       agreement to the MapQuest stockholders, or withdraws or modifies, or
       proposes to withdraw or modify, its recommendation or approval in a
       manner adverse to America Online,

    .  fails to mail this proxy statement/prospectus to MapQuest's
       stockholders when it is available for mailing or fails to include in
       it MapQuest board' recommendation of the merger, including the
       recommendation that the MapQuest stockholders vote in favor of the
       adoption of the merger agreement,

    .  fails to publicly reaffirm its approval and recommendation that
       MapQuest stockholders adopt the merger agreement within two business
       days of a request by America Online,

    .  enters into any letter of intent, agreement in principle,
       acquisition agreement or other similar agreement related to any
       Acquisition Proposal, or takes any other prohibited actions with
       respect to negotiations involving MapQuest as described on pages 46-
       47 of this proxy statement/prospectus,

    .  materially breaches the stock option agreement, or

     obligations under the merger agreement, (1) if any of MapQuest's
     representations or warranties are or become untrue or inaccurate, or (2)
     if MapQuest has breached any of its covenants or agreements contained in
     the merger agreement, in each case so that the corresponding condition
     to completion of the merger would not be met, and in each case where
     such breach or inaccuracy, if curable, has not been cured within 30 days
     after notice to MapQuest of the breach or inaccuracy,

  .  by MapQuest, as long as it is not in material breach of any of its

     any of their covenants or agreements contained in the merger agreement,
     in each case so that the corresponding condition to completion of the
     merger would not be met, and in each case where such breach or
     inaccuracy, if curable, has not been cured within 30 days after notice
     to MapQuest of the breach or inaccuracy, and

  .  by America Online if any stockholder that is a party to the stockholders
     agreement has breached or failed to perform in any material respect its
     obligations under the stockholders agreement, unless such breach or
     failure, individually or in the aggregate, would not reasonably be
     expected to have a material adverse effect on or materially impede the
     parties' ability to consummate the merger.

   MapQuest will pay to America Online a termination fee of $34.6 million if

     completion of the merger would not be met, and when such breach or

     to MapQuest of the breach or inaccuracy, or

  .  any stockholder that is a party to the stockholders agreement has
     breached or failed to perform in any material respect its obligations
     under the stockholders agreement that individually or in the aggregate
     would reasonably be expected to have a material adverse effect on or
     materially impede the ability of the parties to consummate the merger.

   MapQuest has agreed to pay America Online up to $2.5 million of fees and
expenses actually incurred by America Online in connection with the merger
agreement and the merger:

  .  if the merger agreement is terminated in the circumstances identified
     above as giving rise to MapQuest's obligation to pay to America Online
     the termination fee, or

  .  if MapQuest has materially breached the merger agreement and such breach
     remains uncured.

  MapQuest's Employees

   Individuals who are employed by MapQuest or any of its subsidiaries when the
merger is completed will become employees of America Online or one of America
Online's subsidiaries, although America Online may terminate these employees at
any time. After the merger is completed and on a schedule determined by America
Online in connection with the integration of its business with that of
MapQuest's, the employees of MapQuest will be eligible to participate in the
employee benefit plans of America Online to the same extent as any similarly
situated and geographically located employees of America Online. MapQuest
employees will be allowed credit for their service with MapQuest for purposes
of vesting, calculating the number of vacation days to which they are entitled,
subject to a maximum of five incremental days, and participation only, and not
for entitlement, except as provided with respect to vacation, or benefit
accrual purposes, with respect to the America Online employee benefit plans in
which MapQuest employees are allowed to participate.

                                       50
<PAGE>

   If requested to do so by America Online, MapQuest will adopt, prior to the
merger's completion, resolutions to cease all contributions to the MapQuest
Retirement Savings Plan and to terminate the plan immediately prior to the
consummation of the merger. If requested by America Online, these resolutions
will also provide that all of the participants in the plan will be fully vested
in their account balances and that the participants will receive their account
balances as soon as practicable following the consummation of the merger.

  Treatment of MapQuest Stock Options

   America Online will assume each stock option issued by MapQuest, including
those options issued under MapQuest's 1995 Stock Option Plan and 1999 Stock
Plan, each as amended.

   Upon completion of the merger, each outstanding option to purchase MapQuest
common stock will be converted into an option to purchase the number of shares
of America Online common stock equal to 0.31558 multiplied by the number of
shares of MapQuest common stock that would have been obtained before the merger
upon the exercise of each option, rounded down to the nearest whole share. The
exercise price will be equal to the exercise price per share of MapQuest common
stock subject to the option before conversion divided by 0.31558, rounded up to
the nearest whole cent.

   The other terms of each MapQuest option referred to above will continue to
apply, including any provisions providing for acceleration of vesting.

   America Online will file a registration statement on Form S-8 for the shares
of America Online common stock issuable with respect to each MapQuest option
and will use its reasonable best efforts to maintain the effectiveness of that
registration statement for as long as any of the options remain outstanding.

   As of the date of the merger agreement, MapQuest must ensure that no
offerings or options are granted without the approval of America Online and
that MapQuest's employee stock purchase plan is not activated.

   The representations and warranties in the merger agreement are complicated
and not easily summarized. You are urged to carefully read the articles of the
merger agreement entitled "Representations and Warranties of the Company" and
"Representations and Warranties of Parent and Merger Sub."

  Extension, Waiver and Amendment of the Merger Agreement

   We may amend the merger agreement before completion of the merger. However,
after the MapQuest stockholders adopt the merger agreement, no change will be
made that will reduce the amount of or change the type of consideration into
which each share of MapQuest common stock will be converted upon completion of
the merger.

   Either of us 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. If
any of our conditions or other obligations are waived, we will consider the
facts and circumstances at that time and make a determination as to whether a
resolicitation of proxies is appropriate.

The Stock Option Agreement

   The following summary of the stock option agreement is qualified in its
entirety by reference to the complete text of the stock option agreement, which
is incorporated by reference and attached as Annex B to this proxy
statement/prospectus. We urge you to read the full text of the stock option
agreement.

   The stock option agreement grants America Online the option to buy up to
3,571,661 shares of MapQuest common stock at an exercise price of $27.00 per
share. The number of shares issuable upon exercise of the option and the
exercise price of the option are subject to adjustment to prevent dilution.
Based on the number of shares of MapQuest common stock outstanding on December
21, 1999, the option would be exercisable for approximately 10.0% of the
outstanding shares of MapQuest and approximately 9.1% of the outstanding shares
after giving effect to the exercise of the option.

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

   America Online may exercise the option, in whole or part, up to one year
from the date on which America Online first has the right to receive the
termination fee. The option will terminate and not become exercisable upon any
of the following:

  .  completion of the merger,

  .  America Online's written notice to MapQuest effecting the termination of
     the option agreement,

  .  the termination of the merger agreement under circumstances which cannot
     cause the option to become exercisable, or

  .  twelve months after termination of the merger agreement.

   However, if America Online exercises the option to purchase shares of
MapQuest common stock prior to the option's expiration, America Online will
return the right to purchase the shares subject to the option, even after the
option expires.

   If the merger agreement is terminated under circumstances that require
MapQuest to pay America Online a termination fee pursuant to the terms of the
merger agreement, then America Online has the right to require MapQuest to
repurchase the option or, if the option has been exercised by America Online
the shares issued

                                       53
<PAGE>

upon exercise of the option. The stock option agreement provides that in no
event will America Online's total profit under the stock option agreement, less
any termination fee paid by MapQuest under the merger agreement, exceed $34.6
million.

   The stock option agreement grants registration rights to America Online with
respect to the shares of MapQuest common stock represented by the option.

The Stockholders Agreement

   The following summary of the stockholders agreement is qualified in its
entirety by reference to the complete text of the stockholders agreement, which
is incorporated by reference and attached as Annex C to this proxy
statement/prospectus. You are urged to read the full text of the stockholders
agreement.

   The stockholders agreement requires the following MapQuest stockholders vote
all of the shares of MapQuest common stock beneficially owned by them in favor
of the merger:

  .  Trident Capital Partners Fund-I, L.P.,

  .  Trident Capital Partners Fund-I, C.V.,

  .  Highland Capital Partners III Limited Partnership,

  .  Highland Entrepreneurs' Fund III, L.P.,

  .  National Geographic Holdings, Inc.,

  .  Weston Presidio Capital II, L.P.,

  .  Michael J. Mulligan, and

  .  James W. Thomas.

   As of the record date, the MapQuest stockholders who entered into the
stockholders agreement collectively held approximately 26,586,545 shares of
MapQuest common stock, which represented approximately 72.8% of the voting
power of the outstanding shares of MapQuest common stock entitled to vote as of
the record date at the special meeting.

   Each MapQuest stockholder who is a party to the stockholders agreement has
agreed not to sell the MapQuest stock and options owned, controlled or
acquired, either before or after the date of the merger agreement, by that
person except for sales completed earlier than 30 days prior to the date that
the merger is consummated. Additionally, each stockholder agreed that it will
not do any of the following (and nor will it authorize any of its affiliates,
directors, officers, employees or representatives to do any of the following):

  .  solicit, facilitate, initiate or encourage any inquiries or
     communications or the making of any proposal or offer that constitutes,
     or may constitute, an Acquisition Proposal, or

  .  participate or engage in any discussion or negotiations with, or take
     any action with the intent to facilitate the efforts of, any third party
     concerning:

     .  any possible Acquisition Proposal, or

     .  any communication that might reasonably be expected to result in an
        Acquisition Proposal.

   The stockholders agreement will terminate upon the earlier to occur of (1)
the termination of the merger agreement in accordance with its terms, or (2)
the completion of the merger.

The Distribution Agreement

   America Online, Digital City and MapQuest entered into a distribution
agreement simultaneously with the merger agreement. Under the distribution
agreement, MapQuest will provide America Online and Digital City the use and
license of its mapping and routing data and services. America Online will
provide access to these data and services through its network. MapQuest also
will provide the use of certain business information to Digital City so that
visitors to Digital City's website may search the MapQuest databases by a
business or telephone number within a city or state.

   Under the distribution agreement, America Online will pay MapQuest an annual
fee based on the amount of revenue generated as a result of America Online's
use of MapQuest's products and services. The agreement has an initial term with
respect to the core services to be provided over the AOL network of five years,
and America Online has the right to extend the term for three additional one-
year terms, provided that either America Online or MapQuest may decide to
terminate the agreement if the other party has:

  .  materially breached the agreement and not cured such breach within 30
     days,

  .  ceased doing business in the normal course,

  .  been declared insolvent or bankrupt, or has been subjected to any
     proceeding relating to its liquidation.

The agreement with respect to Digital City's access to MapQuest's business
information database expires March 31, 2001. The distribution agreement became
effective upon signing. The parties' obligations and rights under the
distribution agreement are independent of their rights and obligations under
the merger agreement or the other agreements related to the merger and will
remain in effect notwithstanding any termination or amendment of the merger
agreement or the other agreements related to the merger.

                   SHARE OWNERSHIP BY PRINCIPAL STOCKHOLDERS,
                      MANAGEMENT AND DIRECTORS OF MAPQUEST

   The following table sets forth information concerning the beneficial
ownership of common stock of MapQuest as of May 16, 2000 for the following:

  .  each person or entity who is known by MapQuest to own beneficially more
     than 5% of the outstanding shares of MapQuest common stock,

  .  each of MapQuest's current directors,

  .  the chief executive officer and each of the other most highly
     compensated executive officers of MapQuest, and

  .  all directors and executive officers of MapQuest as a group.

   The number and percentage of shares beneficially owned is determined in
accordance with Rule 13d-3 of the Exchange Act and the information is not
necessarily indicative of beneficial ownership for any other purpose. Under
such rule, beneficial ownership includes any shares as to which the individual
or entity has voting power or investment power and any shares that the
individual has the right to acquire within 60 days of May 16, 2000 through the
exercise of any stock option or other right. Unless otherwise indicated in the
footnotes or table, each person or entity has sole voting and investment power
(or shares such powers with his or her spouse) with respect to the shares shown
as beneficially owned.

   The calculation of percentages in the "Percentage of Outstanding Shares"
column in the table below is based upon the number of shares of MapQuest common
stock issued and outstanding on May 16, 2000, plus shares of MapQuest common
stock subject to options held by the respective persons on May 16, 2000 and
exercisable within 60 days thereafter.

   Those stockholders of MapQuest in the table below who have entered into a
stockholders agreement with America Online, agreeing to vote their shares of
MapQuest common stock in favor of the proposed merger, are identified by
footnote.

Technology and Infrastructure

  Geographic Data

   MapQuest maintains a worldwide geographic database suitable for high quality
map production. MapQuest has licensed a significant portion of its data from a
number of sources through non-exclusive term contractual arrangements. MapQuest
currently relies on primary geographic data drawn from data supplied to it
under contract by Navigation Technologies Corporation (NavTech), Geographic
Data Technology, Inc. (GDT), Digital Mapping Technologies, Inc. (DMTI) and
other data suppliers. MapQuest obtains Western European street and major road
data from TeleAtlas, NavTech and AND Mapping BV. Major road data for the rest
of the world is obtained from AND Mapping BV. MapQuest's business relationships
with NavTech and other vendors are currently in good standing. However, should
MapQuest lose access to these sources of third-party data or should the terms
of these contractual arrangements materially change, MapQuest would need to
substitute potentially higher-priced alternatives, including expenses
associated with developing substitute data internally, and MapQuest's business,
financial condition and results of operations could be materially and adversely
affected.

   MapQuest's own proprietary data assets also support its online and
traditional digital mapping products and services. MapQuest has spent
approximately six years developing, and continues to enhance and update, its
USDB, a digital geographic United States database (including adjacent areas of
Canada and Mexico). MapQuest also maintains a graphical image database that
contains over 200,000 archived images, which serves as MapQuest's internal
reference library and is supported by a customized database management system
for image retrieval. In addition, MapQuest has developed a suite of
international city map data which includes over

                                       63
<PAGE>

300 metropolitan maps and over 500 downtown maps of most major international
tourist and business destinations.

   MapQuest plans to update its geographic databases periodically. However, in
view of the complexity of updating several different databases, revising
software and the need for third party geocoding, there can be no assurance that
MapQuest will be able to perform such updates on any fixed schedule.

  Software and Editing Tools

   MapQuest has developed numerous software tools and has customized existing
commercial applications to create and maintain its proprietary digital map
databases and produce its mapping products.

   MapQuest's proprietary software development toolkit, GeoLocate, employs
scalable object-oriented technology and comprises the core tools used to
perform high-speed mapping while maintaining high-quality cartographic display.
Designed with an open architecture, GeoLocate offers platform flexibility in
converting a variety of data formats. MapQuest's extensive investment in
GeoLocate has been leveraged for use in the development of MapQuest's Internet
technology, resulting in the creation of a uniquely scalable, high performance
platform that serves millions of routes and maps on a daily basis. Easy-to-use
consumer interface functionality overlays MapQuest's seamless integration of a
variety of data formats and personalization tools which enable consumers to
save and display maps in their preferred styles.

  System Architecture

   Web pages, maps, and driving directions delivered to MapQuest's customers
and users are generated utilizing a Solaris operating system, Apache web server
software and MapQuest's proprietary mapping applications. Traffic is
distributed and load-balanced across multiple servers via our proprietary
software and equipment provided by F5 Networks which maintain replicated, local
storage of underlying software and data, resulting in minimal interdependencies
between servers. Each server has its own local storage, and all data and
software is replicated across all servers. The system is designed as a
flexible, robust architecture which is dynamically scalable to meet anticipated
future demand. In addition to built-in redundancies, MapQuest operates
automated internal monitoring tools on a continual, full-time basis and
independent third-party monitoring of MapQuest's website is generated at all
times from at least thirty different cities on at least twelve different
national and international Internet backbone providers.

   MapQuest's network, hosting facilities, internal architecture and monitoring
have been deployed to provide high availability, efficiency and redundancy at
every level of the infrastructure. MapQuest's Internet map and route servicing
facilities are located in two Denver, Colorado data centers, a Qwest
Communications Cyber Center hosting facility tied to Qwest's nationwide,
dedicated high speed OC-48 IP network and an Inflow, Inc. hosting facility with
UUNet and other major carrier bandwidth provisioned exclusively for MapQuest's
use. MapQuest and its associated websites are tied to Qwest's and Inflow's
backbones via Cisco routers and multiplexors. Qwest and Inflow do not guarantee
that our Internet access will be uninterrupted, secure, or error free and
MapQuest's operations are dependent on Qwest's and Inflow's ability to protect
their and our systems against damage from fire, power loss, water damage,
telecommunications failure, vandalism, and other malicious acts. Any disruption
in the Internet access provided by Qwest or Inflow could have a material
adverse effect on MapQuest's business, financial condition and results of
operations.

Corporate History

   MapQuest was incorporated in Delaware on March 28, 1994, as GeoSystems
Global Corporation and changed its name to MapQuest.com, Inc. on January 27,
1999. On May 4, 1999, MapQuest completed its initial public offering of common
stock, receiving net proceeds of approximately $61.6 million. MapQuest's
service and product offerings are grouped into three lines of business:
Internet-related Products and Services for Business, Internet Consumer and
Traditional Digital Mapping Products and Services.

Competition

   The markets for MapQuest's products and services are highly competitive.
MapQuest competes for business customers and consumers with companies offering
Internet-based map-enabling technology and publishers and distributors of
traditional media (such as television, radio and print) that use or license
their content for use on the Internet, commercial publishing companies,
corporate materials and information market companies, and governmental
authorities.

   MapQuest expects competition to continue to increase because these markets,
particularly the markets for Internet-related products and services, pose no
substantial barriers to entry. Competition may also increase as a result of
industry consolidation. In addition, MapQuest's licensees may develop products
and services that are equal or superior to MapQuest's or that achieve greater
market acceptance than those of MapQuest. Similarly there can be no assurances
that MapQuest's data suppliers will not develop products and services
competitive with those of MapQuest. Increased competition could result in
reduced markets, loss of market share or less traffic to MapQuest's website,
any of which could have a material adverse effect on MapQuest's business,
financial condition and results of operations.

   MapQuest believes that its ability to compete depends upon many factors,
many of which are beyond its control. These factors include MapQuest's ability
to provide depth, quality and accuracy of destination information, to increase
its sales force and to implement its sales and marketing initiatives, the
introduction and acceptance of new and enhanced products and services developed
either by MapQuest or its competitors and the ease of use of products and
services developed either by MapQuest or its competitors.

Government Regulation

   There is an increasing number of laws and regulations pertaining to the
Internet. In addition, a number of legislative and regulatory proposals are
under consideration by federal, state, local and foreign governments and
agencies. Laws or regulations may be adopted with respect to the Internet
relating to liability for information retrieved from or transmitted over the
Internet, online content regulation, user privacy, taxation and quality of
products and services. Moreover, the applicability to the Internet of existing
laws governing issues such as intellectual property ownership and infringement,
copyright, trademark, trade secret, obscenity, libel, employment and personal
privacy is uncertain and developing. Any new legislation or regulation, or the
application or interpretation of existing laws, may decrease the growth in the
use of the Internet, which could in turn decrease the demand for MapQuest's
service, increase MapQuest's cost of doing business or otherwise have a
material adverse effect on MapQuest's business, financial condition and results
of operations.

  Liability for Information Retrieved from mapquest.com and from the Internet

   Content may be accessed on mapquest.com or on the websites of MapQuest's
distribution partners, and this content may be downloaded by users and
subsequently transmitted to others over the Internet. This could result in
claims against MapQuest based on a variety of theories, including negligence,
copyright or trademark infringement or other theories based on the nature,
publication and distribution of this content. These types of claims have been
brought, sometimes successfully, against providers of Internet services in the
past. MapQuest could also be exposed to liability with respect to third-party
content that may be posted by users in chat rooms or bulletin boards offered by
certain of MapQuest's distribution partners. It is also possible that if any
information, including information deemed to constitute professional advice
such as legal, medical, financial or investment advice, provided on
mapquest.com contains errors or false or misleading information, third parties
could make claims against MapQuest for losses incurred in reliance on such
information. The mapquest.com website contains over fifty human-filtered
annotated links to other websites. As a result, MapQuest may be subject to
claims alleging that, by directly or indirectly providing links to other
websites, MapQuest is liable for copyright or trademark infringement or the
wrongful actions of third parties through their respective websites. The
Communications Decency Act of 1996 provides that, under certain circumstances,
a provider of Internet services shall not be treated as a publisher or speaker
of any information provided by a third-party content provider. This safe harbor
has been interpreted to exempt certain activities of providers of Internet
services. MapQuest's activities may prevent it from being able to take
advantage of this safe harbor provision. While

                                       65
<PAGE>

MapQuest attempts to reduce its exposure to such potential liability through,
among other things, provisions in guide agreements, user policies and
disclaimers, the enforceability and effectiveness of such measures are
uncertain.

   MapQuest's general liability insurance may not cover all potential claims to
which MapQuest is exposed and may not be adequate to indemnify MapQuest for all
liability that may be imposed. Any imposition of liability that is not covered
by insurance or is in excess of insurance coverage could have a material
adverse effect on MapQuest's business, financial condition and results of
operations. Even to the extent that such claims do not result in liability to
MapQuest, MapQuest could incur significant costs in investigating and defending
against such claims. Potential liability for information disseminated through
mapquest.com could lead MapQuest to implement measures to reduce its exposure
to such liability, which may require the expenditure of substantial resources
and limit the attractiveness of MapQuest's service to users.

  Privacy Concerns

   The Federal Trade Commission (FTC) is considering adopting regulations
regarding the collection and use of personal identifying information obtained
from individuals when accessing websites. While MapQuest has implemented or
intends to implement programs designed to enhance the protection of the privacy
of its users, including children, there can be no assurance that such programs
will conform with any regulations adopted by the FTC. The FTC's regulatory and
enforcement efforts may adversely affect the ability to collect demographic and
personal information from users, which could have an adverse effect on
MapQuest's ability to provide highly targeted opportunities for advertisers and
e-commerce marketers. Any such developments would have a material adverse
effect on MapQuest's business, financial condition and results of operations.

   The European Union (EU) has adopted a directive that imposes restrictions on
the collection and use of personal data. This directive could, among other
things, affect U.S. companies that collect information over the Internet from
individuals in EU member countries, and may impose restrictions that are more
stringent than current Internet privacy standards in the United States. This
directive does not, however, define what standards of privacy are adequate. As
a result, there can be no assurance that this directive will not adversely
affect the activities of entities such as MapQuest that engage in data
collection from users in EU member countries.

  Internet Taxation

   A number of legislative proposals have been made at the federal, state and
local level, and by certain foreign governments, that would impose additional
taxes on the sale of goods and services over the Internet and certain states
have taken measures to tax Internet-related activities. Such legislation or
other attempts at regulating commerce over the Internet may substantially
impair the growth of commerce on the Internet and, as a result, adversely
affect MapQuest's opportunity to derive financial benefit from such activities.

  Domain Names

   Domain names are the user's Internet "addresses." The current system for
registering, allocating and managing domain names has been the subject of
litigation, including trademark litigation, and of proposed regulatory reform.
Although MapQuest has registered "mapquest.com" as a trademark, third parties
may bring claims for infringement against MapQuest for the use of this
trademark. There can be no assurance that MapQuest's domain names will not lose
their value, or that MapQuest will not have to obtain entirely new domain names
in addition to or in lieu of its current domain names if reform efforts result
in a restructuring in the current system.

  Jurisdictions

   Due to the global nature of the Internet, it is possible that, although
transmissions by MapQuest over the Internet originate primarily in Denver,
Colorado, the governments of other states and foreign countries might attempt
to regulate MapQuest, MapQuest's business activities, MapQuest's transmissions
or prosecute

                                       66
<PAGE>

MapQuest for violations of their laws which could have a material adverse
effect on MapQuest's business, financial condition and results of operations.
In addition, as MapQuest's service is available over the Internet in multiple
states and foreign countries, such jurisdictions may require MapQuest to
qualify to do business as a foreign corporation in each such state or foreign
country, which could subject MapQuest to taxes and penalties and could result
in the inability of MapQuest to enforce contracts in such jurisdictions.

Intellectual Property

   MapQuest regards its copyrights, trademarks, trade secrets and similar
intellectual property as critical to its success. MapQuest relies upon a
combination of trademark and copyright law, trade secret protection and
contractual restrictions with employees, customers, partners and others to
protect its proprietary rights. MapQuest does not currently hold any patents.
If MapQuest fails to adequately protect its proprietary rights, or if it
becomes involved in intellectual property litigation its business, financial
condition and results of operations could be materially and adversely affected.

   Despite MapQuest's efforts to protect our proprietary rights, third parties
may infringe or misappropriate these rights, which could result in a material
adverse effect on MapQuest's business, financial condition and results of
operations. In the ordinary course of business MapQuest has been, and expects
to continue to be, subject to claims, including claims of alleged infringement
of the trademarks and other proprietary rights of third parties. Furthermore,
the validity, enforceability and scope of protection of proprietary rights in
Internet-related industries are uncertain and still evolving. MapQuest expects
that infringement claims in its markets will increase in number as more
participants enter the market. Such claims and any resultant litigation, should
they occur, could subject MapQuest to significant liability for damages and
could result in the invalidation of its proprietary rights. In addition, even
if MapQuest prevails, such litigation could be time-consuming and expensive to
defend, and could result in the diversion of MapQuest's time and attention, any
of which could materially adversely affect its business, financial condition
and results of operations. Any claims from third parties may also result in
limitation on MapQuest's ability to use the trademarks and other intellectual
property subject to such claims unless it enters into agreements with the third
parties responsible for such claims, which may be unavailable on commercially
reasonable terms.

   MapQuest has also been approached by Unisys concerning a license under U.S.
Patent No. 4,558,302, which covers certain data compression technology commonly
referred to as the Lempel-Zev-Welch or ALZW@ algorithm. Unisys and MapQuest are
presently engaged in negotiations concerning a possible settlement. Unisys has
not filed a lawsuit, although it has suggested the possibility of litigation to
enforce the '302 patent if negotiations are unsuccessful. Under the terms of
the merger agreement, MapQuest may not settle certain claims without America
Online's consent.

Employees

   As of March 31, 2000, MapQuest employed 335 persons, including 56
cartographers, 13 GIS/database analysts, 97 software/systems/Internet
engineers, 108 persons in sales, marketing and customer-support, and 61 persons
in general and administrative areas. None of MapQuest's employees is
represented by a labor union and MapQuest believes it has good employee
relations.

   MapQuest believes that its future success will depend in part on its
continued ability to attract, integrate, retain and motivate highly qualified
sales, technical, and managerial personnel, and upon the continued service of
MapQuest's senior management and key sales and technical personnel. There can
be no assurance that MapQuest will successfully attract, integrate, retain and
motivate a sufficient number of qualified personnel to conduct its business in
the future.

Facilities

   MapQuest's headquarters are located in Mountville, Pennsylvania, where
MapQuest currently leases approximately 62,000 square feet under a ten-year
lease expiring in March 2007. In addition, MapQuest maintains executive offices
in New York, New York, where MapQuest leases approximately 9,000 square feet

                                       67
<PAGE>

under a nine-year lease expiring in May 2008. MapQuest also leases
approximately 7,200 square feet in Columbia, Maryland under a two-year lease
expiring in June 2000, approximately 19,400 square feet in Denver, Colorado
under a three-year lease expiring in November 2002, approximately 11,520 square
feet in Mount Joy, Pennsylvania under a three-year lease expiring in December
2000 and approximately 3,600 square feet in the Hague, Netherlands under a
sixteen-month lease expiring in December 2000. MapQuest also leases sales
office space in Redwood Shores, California, Wakefield, Massachusetts, Chicago,
Illinois, and Atlanta, Georgia. These offices are approximately 250 to 2,200
square feet with lease terms of one month to five years.

Legal Proceedings

   MapQuest has been approached by Unisys concerning a license under U.S.
Patent No. 4,558,302, which covers certain data compression technology commonly
referred to as the Lempel-Zev-Welch or ALZW@ algorithm. Unisys and MapQuest are
presently engaged in negotiations concerning a possible settlement. Unisys has
not filed a lawsuit, although it has suggested the possibility of litigation to
enforce the '302 patent if negotiations are unsuccessful. Under the terms of
the merger agreement, MapQuest may not settle certain claims without America
Online's consent.

   Universal Map Enterprises, Inc. filed a lawsuit against MapQuest and America
Online in the United States District Court in the Western District of New York.
In that lawsuit, Universal Map Enterprises alleges claims against MapQuest for
breach of contract, conversion and specific performance, and against America
Online for tortious interference with business arrangements, in connection with
an alleged agreement to sell MapQuest's online electronic commerce website,
MapStore.com, to Universal Map. Since the commencement of the action, Universal
Map has subsequently agreed to dismiss America Online from the action without
prejudice. Universal Map is seeking to recover $1,000,000 in damages and/or
specific performance of the alleged agreement, plus costs and fees. MapQuest
and Universal Map have entered into a stipulation whereby MapQuest has agreed
not to frustrate the ability of Universal Map to enforce a judgment for
specific performance against MapQuest if so rendered. On February 18, 2000,
Universal Map filed a motion for summary judgment with the court seeking
summary disposition of its claims prior to discovery and trial. MapQuest's
opposition to that motion has been filed, and the motion is fully briefed and
awaiting decision by the court. MapQuest denies liability and intends to
vigorously contest the motion and defend the action. Management does not expect
the claim will have a material adverse effect on MapQuest's financial position,
results of operations, or liquidity.

   On April 6, 2000, Furman Roth, Inc. filed a lawsuit against MapQuest in the
Supreme Court of the State of New York, County of New York. In the lawsuit,
Furman Roth alleges claims against MapQuest for breach of contract, fraud,
quantum meruit and unjust enrichment in connection with alleged services
rendered with respect to certain placement of advertising by MapQuest. Furman
Roth is seeking to recover $1,575,000 in damages, plus unspecified punitive
damages. MapQuest denies liability and intends to vigorously defend against the
complaint. Management does not expect the claim will have a material adverse
effect on MapQuest's financial position, results of operations, or liquidity.

Overview

   MapQuest is a leading online provider of mapping and destination
information. MapQuest provides comprehensive online mapping solutions to
businesses and provides customized maps, destination information and driving
directions to consumers. MapQuest has three lines of business: Internet
business products and services, Internet consumer products and services and
digital mapping products and services.

   Since 1967, MapQuest has provided traditional cartographic products and
services. In 1989, MapQuest began offering digital mapping products and
services. Beginning in 1991, MapQuest introduced map-generating products and
services which evolved into online mapping and routing applications. During the
first quarter of 1996, MapQuest launched mapquest.com and initiated sales and
marketing efforts to build brand awareness and to generate advertising revenues
from its website. In the third quarter of 1996, MapQuest began providing online
mapping and destination information products and services from its website to
companies with an Internet presence and to high-traffic websites offering users
a wide range of information and services on their websites, which are commonly
referred to as portal websites. In 1997, MapQuest increased its focus on its
Internet business and consumer lines of business by devoting significant
resources to the mapquest.com web site and to its other Internet products and
services. In 1998, MapQuest introduced its MapQuest Enterprise Server.
MapQuest's Enterprise Server is designed to provide mapping and routing
capability to high volume websites. In 1999, MapQuest began to focus on
developing wireless and voice applications that allow MapQuest users to access
driving directions and find information about various points of interest.

   MapQuest derives its revenues from three lines of business:

   Business Products and Services. MapQuest provides Internet products and
services to companies with an Internet presence and to portal web sites. These
companies typically contract for MapQuest's services on an annual basis in
consideration for a service fee based on usage and an initial set-up fee.
MapQuest recognizes service fees ratably over the period of the service.
Revenues from the set-up fee are recognized upon completion of the related
installation services. Revenues for software and data licenses relating to
MapQuest business products are recognized upon delivery of the product and if
no significant obligations remain outstanding. Otherwise, revenues are
recognized over the term of the related agreement. Further, under those
agreements where MapQuest has a maintenance or upgrade obligation, MapQuest
recognizes revenue for these obligations over the period of the obligation.
MapQuest has also historically provided business products and services for non-
Internet applications by licensing software and data and by providing
professional services on a time and material basis or a fixed-fee basis.

   Consumer Products and Services. Through mapquest.com, MapQuest derives
revenues primarily from the sale of advertising and sponsorships. Advertising
rates vary depending on whether the advertisements are

                                       69
<PAGE>

delivered to a general audience or a targeted audience based on specific
geographic location. Advertising revenues are typically recognized ratably over
the period in which the advertisements are displayed, provided that no
significant obligations remain and the collection of the resulting receivable
is likely. MapQuest may guarantee its advertisers a pre-set level of
impressions on mapquest.com. Impression refers to a delivery of an
advertisement to a user. If the guaranteed impressions are not met, MapQuest
defers recognition of the corresponding revenue until the guaranteed
impressions are achieved. Sponsorship contracts may have longer terms and may
allow sponsors to be exclusive sponsors of portions of mapquest.com or
particular advertising categories.

   Digital Mapping Products and Services. MapQuest derives revenues from
providing digital mapping services to businesses and from the sale of mapping
products to distributors, retailers, and corporate customers. MapQuest
typically receives fees and payments on a time and material basis or a fixed
fee basis. Revenues from these services are recognized when the projects are
completed. In addition, revenues from long-term contracts are recognized on the
percentage-of-completion method, measured as the number of hours incurred to
date as a percentage of estimated total labor hours for each contract. MapQuest
also licenses software and data for a license fee and/or royalties. License
fees are recognized upon delivery of the software and data and if no
significant obligations remain outstanding. Otherwise, revenues are recognized
over the term of the related agreement. Royalty revenue is recognized upon
receipt of payment or evidence royalties have been earned. With respect to the
sale of mapping products, MapQuest is paid negotiated amounts, depending on
volume, from retailers and distributors, subject to minimum sales and return
arrangements.

   As a result of MapQuest's relatively recent focus on the Internet and the
emerging nature of the Internet markets in which it competes, MapQuest is
limited in its ability to accurately forecast its revenue. MapQuest's current
and future expense levels are based largely on its estimates of future revenue
and are to a large extent fixed. Accordingly, MapQuest may be unable to adjust
spending in a timely manner to compensate for any unexpected revenue shortfall,
and a shortfall in revenue in relation to MapQuest's expectations could have a
material adverse effect on MapQuest's business, financial condition and results
of operations. In addition, MapQuest currently intends to significantly
increase its operating expenses to develop and enhance its technology, to
create, introduce and enhance its service offerings, to acquire and develop
content, to fund increased sales and marketing expenses and to enter into new
strategic agreements. To the extent that such expenses precede or are not
subsequently followed by increased revenue, MapQuest's business, financial
condition and results of operations could be materially adversely affected.

   MapQuest's annual operating results are likely to fluctuate significantly in
the future due to a variety of factors, many of which are outside MapQuest's
control. Factors that will influence MapQuest's operating results include:

  .  MapQuest's ability to retain existing portals and online clients, to
     attract new online clients at a steady rate and to maintain business
     customer and end-user satisfaction,

  .  the announcement or introduction of new websites, Web stores, services
     and products by MapQuest and its competitors,

  .  price competition and margin erosion,

  .  the rate at which the online market for the purchase of products and
     services continues to emerge,

  .  MapQuest's ability to upgrade and develop its systems and
     infrastructure,

  .  the termination of any account that represents a significant portion of
     its sales,

  .  technical difficulties or system downtime,

  .  MapQuest's ability to attract new personnel in a timely and effective
     manner,

  .  MapQuest's ability to increase the proportion of sales from portals and
     online clients,

  .  the failure of Internet bandwidth to increase over time and/or an
     increase in the cost to end-users of obtaining or utilizing Internet
     bandwidth, and

  .  certain U.S. and foreign government regulations.

                                       70
<PAGE>

   MapQuest also may, as inducement to obtain certain strategic contracts,
offer favorable pricing terms to portals, software publishers and online
retailers which would reduce its gross margins. As a result, MapQuest believes
that it will continue to incur operating losses in the future. Due to the
foregoing factors, MapQuest's annual operating results may fall below the
expectations of securities analysts and investors. In such event, the trading
price of the common stock would likely be materially adversely affected.

Three Months Ended March 31, 2000 as Compared to 1999

   Revenues

   Revenues were $6.2 million and $10.4 million for the three months ended
March 31, 1999 and 2000, respectively. The increase in revenues is primarily
attributable to increased business and consumer Internet related revenues. As a
result of MapQuest's increased focus on positioning itself as an Internet
company, the number of business customers using MapQuest's Internet mapping
services increased from 456 at March 31, 1999 to 1,301 at March 31, 2000, an
increase of 185%. The consumer segment also experienced increases in revenue as
a result of increased resources devoted to direct sales of advertising in
addition to MapQuest's third party advertising seller. These increases
reflected in 2000 were partially offset by lower digital mapping services
volume as compared to the same period in 1999. For the three months ended March
31, 2000, business and consumer related revenues and digital mapping revenues
were 71.5% and 28.5% percent of total revenues,

                                       71
<PAGE>


respectively, compared to 49.2% and 50.8% respectively for the three months
ended March 31, 1999. MapQuest expects its percentage of business and consumer
related revenues to continue to increase in the future.

   Cost of Revenues

   Cost of revenues consists primarily of compensation for operations personnel
and related operations costs, including depreciation of operating assets,
third-party data and royalties, print and paper costs for printed products, and
subcontractor costs. Cost of revenues increased from $4.5 million to $7.0
million for the three months ended March 31, 1999 and 2000, respectively. This
increase was primarily due to increased costs associated with adding staff and
related expenses to support the expansion of our Internet products and services
as traffic on the mapquest.com web site grew and as the number of business
clients increased.

   Business and consumer costs increased by $2.9 million, from $1.9 million for
the three months ended March 31, 1999 to $4.8 million for the three months
ended March 31, 2000. As a percent of business and consumer revenue, these
expenses were 64.8% for the three months ended March 31, 2000 compared to 63.6%
for the same period in 1999. The increase in business and consumer costs was
primarily related to increased costs associated with adding staff and related
expenses to support the expansion of our Internet products and services as
traffic on the mapquest.com web site grew and as the number of business clients
increased. Digital mapping services costs decreased by $0.3 million, from $2.5
million to $2.2 million for the three months ended March 31, 1999 and 2000,
respectively. As a percent of digital mapping services revenue, these expenses
were 75.3% for the three months ended March 31, 2000 compared to 81.2% for the
same period in 1999. The decrease in digital mapping services costs was
primarily related to decreased print and paper costs for printed products as a
result of lower digital mapping services revenue.

   Operating Expenses

   Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions, travel-related expenses, sales promotion expenses,
public relations expenses and costs of marketing materials. Sales and marketing
expenses were $6.2 million, or 59.9% of revenues, for the three months ended
March 31, 2000. For the three months ended March 31, 1999, sales and marketing
expenses were $2.8 million, or 45.6% of revenues. This period-to-period
increase was primarily attributable to MapQuest's marketing promotions and
advertising efforts as well as an increase in the number of sales and marketing
personnel and related expenses.

   Product Development. Product development expenses consist primarily of the
costs of developing new products and services and modifying existing products
and services, including software and data. These costs consist primarily of
salaries for product development personnel and related expenses, contract labor
expense and consulting fees. Product development expenses were $1.3 million for
the three months ended March 31, 2000, and $0.8 million for the three months
ended March 31, 1999. As a percentage of revenues, these expenses were 12.1%
and 12.7%, respectively, for the three months ended March 31, 2000 and 1999.
This period-to-period increase in dollar amount was primarily attributable to
MapQuest's commitment to continue to invest in the development of business and
consumer products. The decrease as a percentage of revenue is a result of
higher revenues in the first quarter of 2000 versus the first quarter of 1999.

   General and Administrative. General and administrative expenses consist
primarily of salaries and related expenses for general corporate functions,
including executive, accounting and administrative personnel, and legal
expenses. General and administrative expenses were $1.7 million and $0.9
million for the three months ended March 31, 2000 and 1999, respectively. As a
percentage of revenues, these expenses were 16.0% and 15.2%, respectively, for
the three months ended March 31, 2000 and 1999. This period-to-period increase
was primarily attributable to increased salaries, professional service fees and
other expenses as a result of company growth. Additional costs related to being
a publicly held entity, including additional personnel, as well as directors'
and officers' liability insurance and professional services fees were also
incurred in 2000.

   Income Taxes

   MapQuest paid no income taxes for the three months ended March 31, 1999 and
2000, as MapQuest incurred net operating losses for those periods. Due to the
uncertainty of future profitability, MapQuest has not recognized any potential
future tax benefits of net operating loss carryforwards.

Year Ended December 31, 1999 as Compared to 1998

   Revenues

   Total revenues increased by $9.8 million from $24.7 million in 1998 to $34.5
million in 1999. Revenue from MapQuest's top 10 customers decreased from 27.2%
of total revenues in 1998 to 22.3% in 1999.

   Business Revenues. Business revenues increased by $6.6 million from $6.5
million in 1998 to $13.1 million in 1999. As a result of MapQuest's increased
focus on positioning itself as an Internet company and selling its business-to-
business products and services, the number of customers using MapQuest's
Internet mapping services increased from 356 at year end 1998 to 1,014 at year
end 1999. As a percent of total revenues, business revenues increased from
26.4% in 1998 to 38.0% in 1999.

   Consumer Revenues. Consumer revenues increased by $5.2 million from $1.4
million in 1998 to $6.6 million in 1999. In 1999, MapQuest increased resources
devoted to direct sales of advertising on its consumer site. These additional
resources, combined with MapQuest's third-party advertising sales
representative organizations, were able to generate increased revenue. In
addition, during 1998 MapQuest changed its third-party advertising sales
representative organization and did not earn revenues from third-party sales
representative organizations during the transition. As a percent of total
revenues, consumer revenues increased from 5.6% in 1998 to 19.2% in 1999.

   Digital Mapping Revenues. Digital mapping revenues decreased by $2.0 million
from $16.8 million in 1998 to $14.8 million in 1999. This decrease was due to
both decreased sales of printed products of $1.1 million and decreased mapping
services volume of $0.9 million. As a percent of total revenues, digital
mapping revenues decreased from 68.0% in 1998 to 42.8% in 1999.

   Cost of Revenues

   Cost of revenues consists primarily of compensation for operations personnel
and related operations costs, including depreciation of operating assets,
third-party data and royalties, print and paper costs for printed products, and
subcontractor costs. Cost of revenues increased by $4.4 million, from $17.6
million in 1998 to $22.0 million in 1999. As a percent of revenue, these
expenses were 63.8% for the year ended December 31, 1999 compared to 71.4% for
the same period in 1998. Business and consumer costs increased by $5.8 million,
from $4.8 million in 1998 to $10.6 million in 1999. As a percent of business
and consumer revenue, these expenses were 53.9% for the year ended December 31,
1999 compared to 60.8% for the same period in 1998. The increases in business
and consumer costs were primarily related to increased costs associated with
adding staff and related expenses to support the expansion of our Internet
products and services as traffic on the mapquest.com web site grew and as the
number of business clients increased. Digital mapping services costs decreased
by $1.4 million, from $12.8 million in 1998 to $11.4 million in 1999. As a
percent of digital mapping services revenue, these expenses were 77.0% for the
year ended December 31, 1999 compared to 76.4% for the same period in 1998. The
decrease in digital mapping services costs was primarily related to decreased
print and paper costs for printed products as a result of lower digital mapping
services revenue.

   Operating Expenses

   Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions, travel-related expenses, sales promotion expenses,
public relations expenses and costs of marketing materials. Sales

                                       73
<PAGE>

and marketing expenses increased by $14.7 million from $5.2 million in 1998 to
$19.9 million in 1999. For the year ended December 31, 1999, sales and
marketing expenses were 57.7% of revenues, compared to 21.2% of revenues for
the year ended December 31, 1998. The period-to-period increases are primarily
attributable to MapQuest's marketing promotions and advertising efforts as well
as an increase in the number of sales and marketing personnel and related
expenses.

   Product Development. Product development expenses consist primarily of the
costs of developing new products and services and modifying existing products
and services, including software and data. These costs consist primarily of
salaries for product development personnel and related expenses, contract labor
expense and consulting fees. Product development expenses increased by $3.0
million from $3.0 million in 1998 to $6.0 million in 1999. As a percentage of
revenues, these expenses were 17.4% for the year ended December 31, 1999 and
12.0% for the comparable period in 1998. These period-to-period increases were
primarily attributable to increased business and consumer product development
expenses. MapQuest plans to continue its investment in the development of
business and consumer products in the future.

   General and Administrative. General and administrative expenses consist
primarily of salaries and related expenses for general corporate functions,
including executive, accounting and administrative personnel, and legal
expenses. These expenses increased by $4.6 million from $2.3 million in 1998 to
$6.9 million in 1999. As a percentage of revenues, these expenses were 20.1%
for the year ended December 31, 1999, compared to 9.4% for the same period in
1998. These period-to-period increases were primarily related to increased
salaries, professional service fees and other expenses as a result of company
growth and being a publicly held entity. In addition, MapQuest recorded $1.7
million of non-recurring expenses in the fourth quarter of 1999. These
consisted of charges related to transaction costs associated with potential
acquisitions that were not consummated and expenses associated with certain
third-party patented technology used by mapquest.com.

   Interest Income and Expense, Net

   Interest income was $1.7 million for the year ended December 31, 1999
compared to $0.1 million for the year ended December 31, 1998. This increase
was due to the placement of a large portion of the proceeds from MapQuest's
initial public offering in May of 1999 in cash equivalents and short-term
investments.

   Income Taxes

   MapQuest paid no income taxes in 1998 or 1999. Other than for the fiscal
year ended December 31, 1995, MapQuest has incurred a net loss for each period
since incorporation. As of December 31, 1999, MapQuest had approximately $44.3
million of net operating loss carryforwards for federal income tax purposes,
which expire beginning in 2009. Due to the uncertainty of future profitability,
a valuation allowance equal to the net deferred tax asset has been recorded.
Changes in ownership resulting from transactions among MapQuest's stockholders
and sales of common stock may limit the future annual realization of the tax
net operating loss carryforwards under Section 382 of the Internal Revenue Code
of 1986.


Year Ended December 31, 1998 as Compared to 1997

  Revenues

   Total revenues increased by $3.3 million from $21.4 million in 1997 to $24.7
million in 1998. Revenue for the top 10 customers of MapQuest as a percent of
total revenue decreased from 44.5% in 1997 to 27.2% in 1998.

   Business Revenues. Business revenues increased by $1.7 million from $4.8
million in 1997 to $6.5 million in 1998. This increase was primarily due to an
increase in the number of businesses using MapQuest's products and services and
the introduction of additional products and services. In addition, during 1998
MapQuest introduced its Enterprise Server products and services. As a percent
of total revenues, business revenues increased from 22.2% in 1997 to 26.4% in
1998.

                                       74
<PAGE>

   Consumer Revenues. Consumer revenues increased $0.1 million from $1.3
million in 1997 to $1.4 million in 1998. This increase was due to increased
advertising sales, including advertisements placed on MapQuest's website and
sponsorship advertisements. During 1998, MapQuest changed its third-party
advertising sales representative organization. Consequently, MapQuest did not
earn revenues from third-party advertising sales representative organizations
during this transition. As a percent of total revenues, consumer revenues
decreased from 6.0% in 1997 to 5.6% in 1998.

   Digital Mapping Revenues. Digital mapping revenues increased by $1.4 million
from $15.4 million in 1997 to $16.8 million in 1998. This increase was
primarily due to increased sales of printed products, including the National
Geographic Road Atlas and the National Geographic American Road Atlas. As a
percent of total revenues, digital mapping revenues decreased from 71.8% in
1997 to 68.0% in 1998.

  Cost of Revenues

   Cost of revenues consists primarily of compensation for operations personnel
and related operations costs, including depreciation of operating assets,
third-party data and royalties, print and paper costs for printed products, and
subcontractor costs. Cost of revenues increased by $2.3 million from $15.3
million in 1997 to $17.6 million in 1998. As a percent of revenue, these
expenses were 71.4% for the year ended December 31, 1998 and 71.4% for the same
period in 1997. Digital mapping services costs increased by $2.0 million, from
$10.8 million in 1997 to $12.8 million in 1998. As a percent of digital mapping
services revenue, these expenses were 76.4% for the year ended December 31,
1998 compared to 70.0% for the same period in 1997. The increase in digital
mapping services costs was primarily related to increased print and paper costs
for printed products as a result of higher digital mapping services revenue.
Business and consumer costs increased by $0.3 million, from $4.5 million in
1997 to $4.8 million in 1998. As a percent of business and consumer revenue,
these expenses were 60.8% for the year ended December 31, 1998 compared to
75.1% for the same period in 1997.

  Operating Expenses

   Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions, travel related expenses, sales promotion expenses,
public relations expenses and costs of marketing materials. Sales and marketing
expenses decreased by $2.1 million from $7.3 million in 1997 to $5.2 million in
1998. This decrease reflects lower promotional costs and personnel expenses as
MapQuest implemented expense reduction efforts in early 1998. These expense
reductions included a reduction in personnel, decreased travel expenses and
lower spending for sales promotions involving trade shows and public relations.
These expense reduction efforts were undertaken as MapQuest revised its
business strategy.

   Product Development. Product development expenses are primarily the costs of
developing new products and services and modifying existing products and
services, including software and data. These expenses consist primarily of
salaries for product development personnel and related expenses, contract labor
expense, and consulting fees. Product development expenses decreased by $2.0
million from $5.0 million in 1997 to $3.0 million in 1998. The decrease from
1997 to 1998 was primarily due to decreases in personnel and related expenses
as MapQuest implemented the expense reduction efforts described in the
preceding paragraph in early 1998.

   General and Administrative. General and administrative expenses consist
primarily of payroll and related expenses for MapQuest's executive, accounting
and administrative personnel, professional services and other general corporate
expenses. These expenses increased by $0.5 million from $1.8 million in 1997 to
$2.3 million in 1998. The increase from 1997 to 1998 was primarily due to costs
associated with the hiring of a new Chief Executive Officer and for additional
professional services.

                                       75

  Interest Income and Expense, Net

   Interest income was $0.1 million in both 1997 and 1998.

  Other Income

   Other income decreased $0.1 million from $0.3 million in 1997 to $0.2
million in 1998. This decrease was primarily due to lower equity in the
earnings of a joint venture that serves a number of automobile clubs with trip
routing services.

  Income Taxes

   MapQuest paid no income taxes in 1997 or 1998. Other than for the fiscal
year ended December 31, 1995, MapQuest has incurred a net loss for each period
since incorporation. As of December 31, 1998, MapQuest had approximately $11.7
million of net operating loss carryforwards for federal income tax purposes,
which expire beginning in 2009. Due to the uncertainty of future profitability,
a valuation allowance equal to the deferred tax asset has been recorded.
Changes in ownership resulting from transactions among MapQuest's stockholders
and sales of common stock may limit the future annual realization of the tax
net operating loss carryforwards under Section 382 of the Internal Revenue Code
of 1986.

Liquidity and Capital Resources, Three Months Ended March 31, 2000 and 1999

   MapQuest has financed its operations to date primarily through the sale of
common stock, private placement of equity securities, funds from operations and
bank borrowings. As of March 31, 2000, MapQuest had $36.9 million of cash and
cash equivalents and $2.0 million in short-term investments.

   MapQuest's days sales outstanding in accounts receivable, calculated on a
quarterly basis, were 84 days at March 31, 1999 and 99 days at March 31, 2000.
Due to quarter-to-quarter revenue fluctuations, days sales outstanding in
accounts receivable may periodically exceed 90 days. The average collection
period is a result of the payment practices of some of MapQuest's customers.


   Net cash used in operating activities was $0.7 million for the three months
ended March 31, 1999, and $4.7 million for the three months ended March 31,
2000. In both periods cash used by operating activities was primarily a result
of net losses.

   Net cash used in investing activities was $0.6 million for the three months
ended March 31, 1999. This resulted from the purchases of property and
equipment. Net cash provided by investing activities was $18.9 million for the
three months ended March 31, 2000. This resulted from net sales and maturities
of short-term investments of $21.6 million and property and equipment purchases
of $2.7 million, which included capitalization of software development costs of
$1.0 million.

   Net cash provided by financing activities was $0.9 million for the three
months ended March 31, 1999, and $3.3 million for the three months ended March
31, 2000. In 1999, the amount resulted primarily from borrowings under the
MapQuest line of credit and in 2000 the amount resulted from the exercise of
460,060 stock options.

   MapQuest believes its existing cash and cash equivalents, and short-term
investments, will be sufficient to meet its anticipated cash needs for working
capital and capital expenditures for at least the next twelve months.
MapQuest's future capital requirements will depend on many factors, including
the level of investment we make in new technologies and improvements to
existing technologies and the levels of monthly expenses required to launch new
products and services.

<PAGE>

Liquidity and Capital Resources, Years Ended December 31, 1999 and 1998

   MapQuest has financed its operations to date primarily through the public
sale of common stock, private placement of equity securities, funds from
operations and bank borrowings. As of December 31, 1999, MapQuest had $19.4
million of cash and cash equivalents and $23.6 million in short-term
investments.

   MapQuest's days sales outstanding in accounts receivable, calculated on a
quarterly basis, were 87 days at both December 31, 1998 and 1999. Due to
quarter-to-quarter revenue fluctuations, days sales outstanding in accounts
receivable may periodically exceed 90 days. The average collection period is a
result of the payment practices of some of MapQuest's customers.

   Net cash used in operating activities was $0.8 million for the fiscal year
1998 and $14.8 million for the fiscal year 1999, an increase of $14.0 million.
In 1999, the cash used in operating activities was primarily a result of the
net loss. In addition, trade receivables increased $6.0 million and prepaid
expenses increased $1.7 million, partially offset by increases in advance
billings on contracts, deferred revenue, and accrued personnel costs and other
liabilities of $1.0 million, $2.9 million, and $4.8 million, respectively. The
net cash used in operating activities in 1998 resulted primarily from the net
loss. Other significant operating activities in 1998 include an increase in
trade receivables of $1.5 million and an increase in deferred revenue of $0.7
million.

   Net cash used in investing activities was $1.1 million for the fiscal year
1998 and $28.2 million for the fiscal year 1999. This increase in 1999 is due
to the net purchase of short-term investments of $23.6 million and $4.7 million
in purchases of property and equipment compared to $1.1 million in purchases of
property and equipment during 1998.

   Net cash used in financing activities was less than $0.1 million for the
fiscal year 1998, and net cash provided by financing activities was $61.9
million for the fiscal year 1999. The increase in 1999 resulted primarily from
the issuance of common stock, net of the redemption of preferred stock.

   MapQuest's capital commitments for the fiscal year 1998 and the fiscal year
1999 consisted of obligations under operating leases. Management anticipates
that it will continue to invest in capital expenditures in order to meet its
anticipated growth in operations.

   In May 1999, MapQuest completed an initial public offering of 4,600,000
shares of its common stock at a public offering price of $15 per share, which
generated approximately $61.6 million in net proceeds to MapQuest.

   Upon the closing of MapQuest's initial public offering in May 1999, all of
the outstanding shares of MapQuest's series A and series C preferred stock were
converted into 27,122,455 shares of common stock and all of the outstanding
shares of MapQuest's series B preferred stock were redeemed for approximately
$8.7 million.

   During June 1999, the underwriters of MapQuest's initial public offering
exercised an over-allotment option for 597,990 shares of MapQuest's common
stock at the initial public offering price of $15 per share, which generated
approximately $8.3 million in net proceeds to MapQuest.

   MapQuest believes its existing cash and cash equivalents, and short-term
investments will be sufficient to meet its anticipated cash needs for working
capital and capital expenditures for at least the next twelve months.
MapQuest's future capital requirements will depend on many factors, including
the level of investment MapQuest intends to make in new technologies and
improvements to existing technologies and the levels of monthly expenses
required to launch new products and services.

Liquidity and Capital Resources, Years Ended December 31, 1998 and 1997

   Prior to the initial public offering, MapQuest financed its operations
primarily through the private placement of equity securities, funds from
operations and bank borrowings. As of December 31, 1998, MapQuest had $0.6
million of cash and cash equivalents.

   MapQuest's days sales outstanding in accounts receivable, calculated on a
quarterly basis, were 86 days and 87 days at December 31, 1997 and 1998,
respectively. However, due to revenues fluctuating on a quarter-to-quarter
basis, average days sales outstanding in accounts receivable may periodically
exceed 90 days. The average collection period is a result of the payment
practices of some of MapQuest's customers.

   Net cash used in operating activities was $9.5 million in 1997 and $0.8
million in 1998. In 1997, cash used by operating activities was primarily a
result of the net loss and increased working capital. In 1998, cash used by
operating activities was primarily a result of the net loss.

   Net cash provided by financing activities was $11.4 million in 1997. In
1997, cash provided by financing activities was primarily attributable to net
proceeds from the issuance of convertible preferred stock.

   Net cash used in investing activities was $1.3 million in 1997 and $1.1
million in 1998. Cash used in investing activities in each period was primarily
related to purchases of property and equipment.

New Accounting Pronouncements

   In December 1999, the Securities and Exchange Commission released Staff
Accounting Bulletin ("SAB") No. 101 "Revenue Recognition in Financial
Statements." SAB 101, as amended, provides additional guidance in applying
generally accepted accounting principles for revenue recognition in financial
statements. MapQuest plans to adopt any changes it believes to be mandated by
the SAB no later than the second quarter of 2000. MapQuest does not expect the
SAB to have a material impact on the financial position or results of
operations of MapQuest.

Quantitative and Qualitative Disclosures About Market Risk

   MapQuest does not hold derivative financial instruments or derivative equity
securities in its investment portfolio. MapQuest's policy is to invest excess
cash in debt instruments of the U.S. Government and its agencies, and of high
quality corporate issuers with maturities ranging primarily from one day to
less than six months. These securities are subject to interest-rate risk and
will decrease in value if interest rates increase. Due to the short-term nature
of these investments, MapQuest believes that the risk associated with interest-
rate fluctuations does not pose a material risk to it. MapQuest's operations
are conducted primarily in the United States and as such are not subject to
material foreign currency exchange rate risk.

          COMPARISON OF RIGHTS OF HOLDERS OF MAPQUEST COMMON STOCK AND
                          AMERICA ONLINE COMMON STOCK

   America Online and MapQuest are both organized under the laws of the State
of Delaware. Any differences, therefore, in the rights of holders of America
Online capital stock and MapQuest capital stock arise primarily from
differences in their respective certificates of incorporation and by-laws. Upon
completion of the merger, holders of MapQuest common stock will become holders
of America Online common stock and their rights will be governed by Delaware
law, the America Online restated certificate of incorporation and the America
Online restated by-laws.

   This section of the proxy statement/prospectus describes the material
differences between the rights of America Online stockholders and MapQuest
stockholders. This section does not include a complete description of all
differences among the rights of these stockholders, nor does it include a
complete description of the specific rights of these stockholders. In addition,
the identification of some of the differences in the rights of these
stockholders as material is not intended to indicate that other differences
that are equally important do not exist. You are urged to read carefully the
relevant provisions of Delaware law, as well as the restated certificate of
incorporation and restated by-laws of America Online and the certificate of
incorporation and by-laws of MapQuest.

Capitalization

  Common Stock

   Both MapQuest and America Online have only one class of common stock issued
and outstanding. All shares of America Online common stock are identical and
entitle each holder to identical rights and privileges.

   Holders of both America Online and MapQuest common stock have the right to
cast one vote for each share of their respective common stock held of record on
all matters submitted to a vote of stockholders, including the election of
directors. Neither holders of America Online common stock nor holders of
MapQuest common stock have cumulative voting rights.

  Preferred Stock

   Both of our certificates of incorporation provide that our boards of
directors are authorized to provide for the issuance of shares of undesignated
preferred stock in one or more series, and to fix the designations, powers,
preferences and rights of the shares of each series and any qualifications,
limitations or restrictions thereof.

   The number of authorized shares of America Online undesignated preferred
stock may be increased by the affirmative vote of the holders of a majority of
America Online's common stock, without a vote of the holders of preferred
stock, unless their vote is required pursuant to the terms of any preferred
stock then outstanding. The number of authorized shares of undesignated
preferred stock of America Online may be reduced or eliminated by the
affirmative vote of the holders of 80% of the outstanding capital stock of
America Online entitled to vote in the election of directors, voting together
as a single class.

Classified Board of Directors

   Delaware law provides that a corporation's board of directors may be divided
into various classes with staggered terms of office. Both MapQuest's and
America Online's boards of directors are divided into three classes, as nearly
equal in size as possible, with one class being elected annually. Members of
America Online's board of directors are elected to serve a term of three years
and until their successors are elected and qualified. America Online's
classified board of directors may make it more difficult for a third party to
gain control of America Online.

                                       79
<PAGE>

Number of Directors

   America Online's board of directors currently has eleven members. The number
of directors on America Online's board may only be changed by a vote of a
majority of the directors, subject to the rights of the holders of any
outstanding series of America Online preferred stock to elect additional
directors. There is currently no preferred stock of America Online outstanding.

   MapQuest's board of directors currently consists of five directors. The
number of directors on MapQuest's board shall not be less than three nor more
than nine, the exact number of which is fixed from time to time by the board of
directors.

Removal of Directors

   America Online directors, or the entire America Online board, may be removed
for cause by the affirmative vote of the holders of at least 80% of the
outstanding shares of capital stock of America Online entitled to vote in the
election of directors, voting together as one group.

   America Online's restated certificate of incorporation states that "cause"
means:

  .  conviction of a felony,

  .  declaration of unsound mind by order of a court,

  .  gross dereliction of duty, and

  .  commission of an action which constitutes intentional misconduct or a
     knowing violation of law if that action results in both an improper
     substantial personal benefit and a material injury to America Online.

   MapQuest directors, or the entire MapQuest board, may be removed for cause
by the affirmative vote of the holders of a majority of the MapQuest shares
then entitled to vote in the election of directors. Neither MapQuest's
certificate of incorporation nor by-laws defines "cause." Delaware law provides
that unless otherwise provided in the certificate of incorporation or by-laws
of a company, any director can be removed, with or without cause, by the
holders of a majority of the shares entitled to vote for the election of
directors of such company.

Filling Vacancies on the Board of Directors

   Vacancies in either of our boards of directors, including vacancies
resulting from newly created directorships resulting from any increase in the
authorized number of directors, may be filled only by a majority vote of the
directors then in office, though less than a quorum. Delaware law provides that
if, at the time of the filling of any vacancy or newly created directorship,
the directors then in office constitute less than a majority of the authorized
number of directors, the Delaware Court of Chancery may, upon application of
any stockholder or stockholders holding at least 10% of the total voting power
of the outstanding stock having the right to vote for such directors, order an
election to be held to fill the vacancy or replace the directors selected by
the directors then in office.

   Newly created directorships or decreases in directorships in both of our
boards of directors are to be apportioned among the classes of directors so as
to make all classes as nearly equal in number as practicable, provided that no
decreases in the number of directors on either of our board of directors may
shorten the term of any director then in office.

   To the extent reasonably possible, any newly created America Online
directorship will be added to the class of directors whose term of office is to
expire at the latest date following the creation of that directorship, unless
otherwise provided for by resolution of the majority of the directors then in
office. Any newly

                                       80
<PAGE>

eliminated America Online directorship will be subtracted from the class whose
office is to expire at the earliest date following the elimination of the
directorship, unless otherwise provided for by resolution of the majority of
the directors then in office.

Limits on Stockholder Action by Written Consent

   Delaware law provides that, unless otherwise stated in the certificate of
incorporation, any action which may be taken at an annual meeting or special
meeting of stockholders may be taken without a meeting, if a consent in writing
is signed by the holders of the outstanding stock having the minimum number of
votes necessary to authorize the action at a meeting of stockholders.

   The America Online restated certificate of incorporation limits
stockholders' ability to act by written consent by requiring any action by
written consent to be unanimous.

   MapQuest stockholders may not take action by written consent.

Ability to Call Special Meetings

   Special meetings of America Online stockholders may be called by America
Online's board of directors, by affirmative vote of a majority of the total
number of authorized directors, or by the chief executive officer.

   Special meetings of MapQuest stockholders may be called by a majority of
MapQuest's board of directors, by the chairman of the board, by its president
or at the request of stockholders holding at least 20% of the outstanding
MapQuest shares of stock generally entitled to vote.

Advance Notice Provisions for Stockholder Nominations and Proposals

   Under the America Online restated by-laws, in order for a stockholder to
nominate candidates for election to America Online's board of directors at any
annual or any special stockholder meeting at which the board of directors has
determined that directors will be elected, timely written notice must be given
to the Secretary of America Online before the annual or special meeting.
Similarly, in order for a stockholder to propose business to be brought before
any annual stockholder meeting, timely written notice must be given to the
Secretary of America Online before the annual meeting.

   Under America Online's restated by-laws, to be timely, notice of stockholder
nominations or proposals to be made at an annual stockholder meeting must be
received by the secretary of America Online no less than 60 days nor more than
90 days before the first anniversary of the preceding year's annual meeting. If
the date of the annual meeting is more than 30 days before or more than 60 days
after the anniversary of the preceding year's annual meeting, notice will also
be timely if delivered within 10 days of the date on which public announcement
of the meeting was first made by America Online. In the case of a special
meeting, notice of a stockholder nomination must be received no later than 60
days nor more than 90 days before a special meeting at which directors are to
be elected or within 10 days of the date on which public announcement of the
special meeting was first made by America Online.

   In addition, if the number of directors to be elected is increased and no
public announcement is made by America Online naming all of the nominees or
specifying the size of the increased board of directors at least 70 days before
the first anniversary of the preceding year's annual meeting, or, if the date
of the increase is more than 30 days before or 60 days after the anniversary of
the preceding year's annual meeting, at least 70 days before the annual
meeting, then a stockholder's notice will be considered timely, with respect to
the nominees for any new positions created by the increase, if it is delivered
to the secretary of America Online within 10 days of the date on which public
announcement of the meeting was first made by America Online.

   A stockholder's notice to America Online must set forth all of the
following:

  .  all information required to be disclosed in solicitations of proxies for
     election of directors, or information otherwise required by applicable
     law, relating to any person that the stockholder proposes

                                       81
<PAGE>

     to nominate for election or re-election as a director, including that
     person's written consent to being named in the proxy statement as a
     nominee and to serving as a director if elected,

  .  a brief description of the business the stockholder proposes to bring
     before the meeting, the reasons for conducting that business at that
     meeting and any material interest of the stockholder in the business
     proposed, and

  .  the stockholder's name and address as they appear on America Online's
     books and the class and number of shares of America Online which are
     beneficially owned by the stockholder.

   Stockholder nominations and proposals will not be brought before any
America Online stockholder meeting unless the nomination or proposal was
brought before the meeting in accordance with America Online's stockholder
advance notice procedure.

   The chairman of the America Online stockholder meeting has the power to
determine whether the nomination or proposal was made by the stockholder in
accordance with the advance notice procedures set forth in America Online's
restated by-laws. If the chairman determines that the nomination or proposal
is not in compliance with America Online's advance notice procedures, the
chairman may declare that the defective proposal or nomination will be
disregarded.

   The MapQuest by-laws allow stockholders to nominate candidates for election
to MapQuest's board of directors at any annual or any special stockholder
meeting at which the board of directors has determined that directors will be
elected. In addition, the by-laws allow stockholders to propose business to be
brought before any annual stockholder meeting. However, nominations and
proposals may only be made by a stockholder who has given timely written
notice to the secretary of MapQuest before the annual or special stockholder
meeting.

   Under MapQuest's by-laws, to be timely, notice of stockholder nominations
to be made at an annual stockholder meeting must be received by the secretary
of MapQuest no less than 60 days before the first anniversary of the preceding
year's annual stockholder meeting. If the date of the annual meeting is more
than 30 days before or more than 60 days after the anniversary of the
preceding year's annual stockholder meeting, notice will also be timely if
delivered within 10 days of the date on which public announcement of the
meeting was first made by MapQuest.

   Under MapQuest's by-laws, to be timely, notice of a stockholder nomination
for the election of directors to be made at a special stockholder meeting must
be received no less than 7 days following the date on which notice of the
special meeting was first made by MapQuest.

   In addition, under the by-laws, to be timely, notice of stockholder to
propose business must be received by the secretary of MapQuest no less than 60
days prior to the annual meeting. If notice is given less than 70 days or
prior public disclosure of the date of the meeting is given or made to
stockholders, notice to be timely must be received no later than 10 days
following the earlier of the day notice of the annual meeting was mailed or
publicly disclosed.

   A stockholder's notice to MapQuest must set forth all of the following:

  .  all information required to be disclosed in solicitations of proxies for
     election of directors, or information otherwise required by applicable
     law, relating to any person that the stockholder proposes to nominate
     for election or re-election as a director, including that person's
     written consent to being named in the proxy statement as a nominee and
     to serving as a director if elected,

  .  the name and address of the stockholder who intends to make the
     nomination and of the person or persons to be nominated,

  .  a representation that the stockholder is a holder of record of stock of
     the corporation entitled to vote at such meeting and intends to appear
     in person or by proxy at the meeting to nominate the person or persons
     specified in the notice,

                                      82
<PAGE>

  .  a description of all arrangements or understandings between the
     stockholder, each nominee or any other person or persons (naming such
     person or persons) pursuant to which the nomination or nominations are
     to be made by the stockholder, and

  .  a brief description of the business the stockholder proposes to bring
     before the meeting, the reasons for conducting that business at that
     meeting and any material interest of the stockholder in the business
     proposed.

   Stockholder nominations and business proposals will not be brought before
any MapQuest stockholder meeting unless the nominations or proposal was brought
before the meeting in accordance with MapQuest's stockholder advance notice
procedure.

Amendment of Certificate of Incorporation

   Under Delaware law, an amendment to the certificate of incorporation of a
corporation requires the approval of the corporation's board of directors and
the approval of holders of a majority of the outstanding stock entitled to vote
upon the proposed amendment, unless a higher vote is required by the
corporation's certificate of incorporation.

   America Online's restated certificate of incorporation provides that the
affirmative vote of the holders of at least 80% or more of the voting power of
all of the then outstanding America Online capital stock entitled to vote
generally in the election of directors, voting together as one group, is
required to:

  .  reduce or eliminate the number of authorized shares of America Online
     common stock or the number of authorized shares of America Online
     preferred stock, or

  .  amend, or repeal, or adopt provisions inconsistent with, the provisions
     of America Online's restated certificate of incorporation relating to:

    .  undesignated preferred stock,

    .  the board of directors, including the powers and authority expressly
       conferred upon the board of directors, the number of members, board
       classification, vacancies and removal,

    .  the manner in which stockholder action may be effected,

    .  amendments to America Online's restated by-laws,

    .  business combinations with interested stockholders of America
       Online,

    .  indemnification of officers and directors of America Online, and

    .  the personal liability of directors of America Online or its
       stockholders for breaches of fiduciary duty.

   MapQuest's certificate of incorporation does not contain a provision that
requires a vote greater than that required by Delaware law in order to amend
its certificate of incorporation.

Amendment of By-laws

   Under Delaware law, stockholders entitled to vote have the power to adopt,
amend or repeal by-laws. In addition, a corporation may, in its certificate of
incorporation, confer such power upon the board of directors. The stockholders
always have the power to adopt, amend or repeal the by-laws, even though the
board may also be delegated such power.

   America Online's restated certificate of incorporation authorizes the
America Online board of directors to adopt, amend or repeal any provision of
America Online's restated by-laws by the affirmative vote of a majority of the
total number of authorized directors. American Online's restated certificate of
incorporation

                                       83
<PAGE>

further provides that any provision of America Online's restated by-laws may be
adopted, amended and repealed by the affirmative vote of the holders of at
least 80% of the then outstanding shares of capital stock entitled to vote
generally in the election of directors, voting together as one group.

   MapQuest's board of directors and stockholders have concurrent power to
adopt, amend or repeal MapQuest's by-laws. All such modifications must be
approved by either a majority of the entire board of directors or the holders
of a majority of the aggregate voting power of the outstanding capital stock
entitled to vote.

State Anti-Takeover Statutes

   Under the business combination statute of Delaware law, a corporation is
prohibited from engaging in any business combination with an interested
stockholder who, together with its affiliates or associates, owns, or who is an
affiliate of the corporation and within a three-year period did own, 15% or
more of the corporation's voting stock for a three-year period following the
time the stockholder became an interested stockholder, unless:

  .  prior to the time the stockholder became an interested stockholder, the
     board of directors of the corporation approved either the business
     combination or the transaction which resulted in the stockholder
     becoming an interested stockholder;

  .  the interested stockholder owned at least 85% of the voting stock of the
     corporation, excluding specified shares, upon consummation of the
     transaction which resulted in the stockholder becoming an interested
     stockholder; or

  .  at or subsequent to the time the stockholder became an interested
     stockholder, the business combination is approved by the board of
     directors of the corporation and authorized by the affirmative vote, at
     an annual or special meeting and not by written consent, of at least 66
     2/3% of the outstanding voting shares of the corporation, excluding
     shares held by that interested stockholder.

   A business combination generally includes:

  .  mergers, consolidations and sales or other dispositions of 10% or more
     of the assets of a corporation to or with an interested stockholder;

  .  specified transactions resulting in the issuance or transfer to an
     interested stockholder of any capital stock of the corporation or its
     subsidiaries; and

  .  other transactions resulting in a disproportionate financial benefit to
     an interested stockholder.

   The provisions of the Delaware business combination statute do not apply to
a corporation if, subject to certain requirements, the certificate of
incorporation or by-laws of the corporation contain a provision expressly
electing not to be governed by the provisions of the statute or the corporation
does not have voting stock listed on a national securities exchange, authorized
for quotation on an inter-dealer quotation system of a registered national
securities association or held of record by more than 2,000 stockholders.

   Neither America Online nor MapQuest has adopted any provision in their
respective certificates of incorporation to "opt-out" of the Delaware business
combination statute, and so the statute is applicable to business combinations
involving either America Online or MapQuest.

Limitation on Personal Liability of Directors and Officers

   Delaware law provides that a corporation may include in its certificate of
incorporation a provision limiting or eliminating the liability of its
directors to the corporation and its stockholders for monetary damages arising
from a breach of fiduciary duty, except for:

  .  a breach of the duty of loyalty to the corporation or its stockholders;

                                       84
<PAGE>

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

  .  payment of a dividend or the repurchase or redemption of stock in
     violation of Delaware law; or

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

   Both of our respective certificates of incorporation provide that, to the
fullest extent Delaware law permits the limitation or elimination of the
liability of directors, none of our respective directors will be liable to
America Online or MapQuest, as applicable, or our respective stockholders for
monetary damages for breach of fiduciary duty as a director.

Indemnification of Directors and Officers

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

   In addition, Delaware law provides that a corporation may advance to a
director or officer expenses incurred in defending any action upon receipt of
an undertaking by the director or officer to repay the amount advanced if it is
ultimately determined that he or she is not entitled to indemnification.

   Our respective certificates of incorporation and by-laws provide that any
person who is or was a party or is threatened to be a party to, or is involved
in any action, suit, or proceeding, whether civil, criminal, administrative or
investigative, because that person is or was a director, officer or employee,
or is or was serving at the request of either of us as a director, officer,
employee or agent of another corporation or of a partnership, joint venture,
trust or other enterprise, will be indemnified against expenses, including
attorney's fees, and held harmless by each of us to the fullest extent
permitted by the Delaware General Corporation Law. The indemnification rights
conferred by each of us are not exclusive of any other right to which persons
seeking indemnification may be entitled under any statute, our respective
certificates of incorporation or by-laws, any agreement, vote of stockholders
or disinterested directors or otherwise. In addition, each of us is authorized
to purchase and maintain insurance on behalf of its directors and officers.

   Additionally, each of us may pay expenses incurred by our directors or
officers in defending a civil or criminal action, suit or proceeding because
that person is a director or officer, in advance of the final disposition of
that action, suit or proceeding. However, such payment will be made only if we
receive an undertaking by or on behalf of that director or officer to repay all
amounts advanced if it is ultimately determined that he or she is not entitled
to be indemnified by us, as authorized by our respective certificates of
incorporation and by-laws.

Fair Price Provision

   America Online's restated certificate of incorporation contains a "fair
price" provision which states that certain "business combinations" with any
"interested stockholder" may not be completed without an affirmative vote of
the holders of at least 80% of the voting power of all voting stock of America
Online, voting together as one group, in addition to any other vote required by
America Online's restated certificate of incorporation or Delaware law.

   This fair price provision does not apply if the business combination will
have been approved either by a majority of the directors of America Online who
are not affiliated with the interested stockholder, of which there must be at
least two, or if certain price and procedural requirements, set forth in detail
in America Online's restated certificate of incorporation, are met.


                                       85
<PAGE>

   The business combinations to which America Online's fair price provision
applies include:

  .  any merger or consolidation of America Online or any subsidiary with any
     interested stockholder or any other corporation, whether or not itself
     an interested stockholder, which is, or after the merger or
     consolidation, would be, an affiliate of an interested stockholder who
     was an interested stockholder before the transaction,

  .  any sale, lease, exchange, mortgage, pledge, transfer or other
     disposition, in one transaction or a series of transactions, to or with
     any interested stockholder or any affiliate of any interested
     stockholder, of any assets of America Online or any subsidiary having an
     aggregate fair market value, as determined in accordance with America
     Online's restated certificate of incorporation, equaling or exceeding
     10% or more of the assets of America Online,

  .  the issuance or transfer by America Online or any subsidiary, in one
     transaction or a series of transactions, of any securities of America
     Online or any subsidiary, to any interested stockholder or any affiliate
     of any interested stockholder in exchange for cash, securities or other
     property having an aggregate fair market value equaling or exceeding 10%
     of the combined fair market value of the outstanding shares of voting
     stock of America Online, except for any issuance or transfer pursuant to
     an employee benefit plan of America Online or any subsidiary,

  .  the adoption of any plan or proposal for the liquidation or dissolution
     of America Online proposed by or on behalf of an interested stockholder
     or any affiliate of any interested stockholder, and

  .  any reclassification of securities, including any reverse stock split,
     or recapitalization of America Online, or any merger or consolidation of
     America Online with any of its subsidiaries or any other transaction
     which has the effect, directly or indirectly, of increasing the
     proportionate amount of the outstanding shares of any class of equity or
     convertible securities of America Online or any subsidiary which is
     directly or indirectly owned by any interested stockholder or any
     affiliate of any interested stockholder.

   America Online's fair price provision defines an "interested stockholder" as
any person, other than America Online or any America Online holding company or
subsidiary, who or which:

  .  is the beneficial owner, directly or indirectly, of more than 15% of the
     voting power of the outstanding voting stock of America Online,

  .  is an affiliate of America Online and at any time within the two-year
     period immediately before the date in question was the beneficial owner,
     directly or indirectly, of 15% or more of the voting power of the
     outstanding voting stock of America Online, and

  .  is an assignee of or has otherwise succeeded to any shares of voting
     stock of America Online which were, at any time within the two-year
     period immediately before the date in question, beneficially owned by
     any interested stockholder, if the assignment or succession did not
     occur as part of an initial public offering.

   The "fair price" provision may deter a purchaser from using two-tiered
pricing and similar unfair or discriminatory tactics in an attempt to acquire
America Online. The provision could also have the effect of discouraging a
third party from making a tender or exchange offer for America Online, even
though an offer by a third party might be beneficial to America Online and its
stockholders.

   MapQuest's certificate of incorporation and by-laws do not contain a
provision similar to the fair price provision that is contained in America
Online's restated certificate of incorporation.

Stockholder Rights Plan

   In 1998, America Online adopted a stockholder rights plan pursuant to a
rights agreement with BankBoston, N.A., as rights agent. Set forth below is a
summary of the material provisions of the rights

                                       86
<PAGE>

agreement. The summary does not include a complete description of all of the
terms of the rights agreement. You are urged to read carefully the relevant
provisions of America Online's rights plan, copies of which will be sent to
America Online stockholders upon request. See "Where You Can Find More
Information."

   Exercisability of Rights. Under the America Online rights agreement, one
right, referred to as an America Online right, attaches to each share of
America Online common stock outstanding and, when exercisable, entitles the
registered holder to purchase from America Online one quarter of one one-
thousandth of a share of America Online series A-1 preferred stock at an
initial purchase price of $900, subject to customary antidilution adjustments.

   The America Online rights will not become exercisable until the earlier of:

  .  ten days following a public announcement that a person has become the
     beneficial owner of 15% or more of the America Online common stock then
     outstanding; and

  .  ten business days, or such later date as may be determined by the board
     of directors of America Online, following the commencement of, or the
     announcement of an intention to commence, a tender offer or exchange
     offer that would result in a person becoming the beneficial owner of 15%
     or more of the America Online common stock then outstanding.

   In connection with the proposed merger between America Online and
TimeWarner, the America Online rights agreement was amended to provide that the
America Online rights will not become exercisable solely by reason of the
merger agreement, the stock option agreements and the completion of the
transactions contemplated in the proposed merger between America Online and
TimeWarner.

   "Flip In" Feature. In the event a person becomes the beneficial owner of 15%
or more of the America Online common stock outstanding, each holder of an
America Online right, except for that person, will have the right to acquire,
upon exercise of the America Online right, instead of one quarter of one-
thousandth of a share of America Online series A-1 preferred stock, shares of
America Online common stock having a value equal to twice the exercise price of
the America Online right. For example, if we assume that the initial purchase
price of $900 is in effect on the date that the flip-in feature of the America
Online rights is exercised, any holder of an America Online right, except for
the person that has become the beneficial owner of 15% or more of the America
Online common stock then outstanding, may exercise his or her America Online
right by paying to America Online $900 in order to receive from America Online
shares of America Online common stock having a value equal to $1,800.

   "Exchange" Feature. At any time after a person becomes the beneficial owner
of 15% or more, but less than 50%, of the America Online common stock then
outstanding, the board of directors of America Online may, at its option,
exchange all or some of the America Online rights, except for those held by
such person, for America Online common stock at an exchange ratio of one share
of America Online common stock for each America Online right, subject to
adjustment, and cash instead of fractional shares, if any. Use of this exchange
feature means that eligible America Online rights holders would not have to pay
a purchase price before receiving shares of America Online common stock.

   "Flip Over" Feature. In the event that, after a person acquires 15% or more
of the America Online common stock then outstanding:

  .  America Online merges into another entity;

  .  another entity merges into America Online; or

  .  America Online sells more than 50% of its assets or earning power,

then each holder of an America Online right, except for a person that is the
beneficial owner of 15% or more of the America Online common stock then
outstanding, will have the right to receive, upon exercise of the

                                       87
<PAGE>

America Online right, the number of shares of the acquiring company's common
stock having a value equal to twice the exercise price of the America Online
right.

   Redemption of Rights. At any time prior to the earlier to occur of:

  .  any public announcement that a person has become the beneficial owner of
     15% or more of the America Online common stock then outstanding; and

  .  May 12, 2008,

the board of directors of America Online may redeem all of the America Online
rights at a redemption price of $0.001 per right, subject to adjustment. The
right to exercise the America Online rights will terminate upon redemption, and
at that time, the holders of the America Online rights will have the right to
receive only the redemption price for each America Online right they hold.

   Amendment of Rights. At any time before a person becomes the beneficial
owner of 15% or more of the America Online common stock then outstanding, the
terms of the existing America Online rights agreement may be amended by the
board of directors of America Online without the approval of the holders of the
rights. However, after the date any person acquires at least 15% of America
Online's outstanding common stock, the rights agreement may not be amended in
any manner that would adversely affect the interests of the holders of the
America Online rights, excluding the interests of the acquiror.

   Termination of Rights. If not previously exercised, the America Online
rights will expire on May 12, 2008, unless America Online earlier redeems or
exchanges the America Online rights or extends the expiration date.

   Anti-Takeover Effects. The America Online rights have anti-takeover effects.
Once the America Online rights have become exercisable, in most cases the
America Online rights will cause substantial dilution to a person that attempts
to acquire or merge with America Online. Accordingly, the existence of the
America Online rights may deter potential acquirors from making a takeover
proposal or a tender offer. The America Online rights should not interfere with
any merger or other business combination approved by the board of directors of
America Online because America Online may redeem the America Online rights and
because the America Online board of directors can amend the America Online
rights agreement so that a transaction approved by the America Online board of
directors would not cause the America Online rights to become exercisable.

   Series A-1 Preferred Stock. In connection with the creation of the America
Online rights, the board of directors of America Online authorized the issuance
of 500,000 shares of America Online preferred stock designated as America
Online series A-1 junior participating preferred stock.

   America Online designed the dividend, liquidation, voting and redemption
features of the America Online series A-1 preferred stock so that the value of
one quarter of one-thousandth of a share of America Online series A-1 preferred
stock approximates the value of one share of America Online common stock.
Shares of America Online series A-1 preferred stock may only be purchased after
the America Online rights have become exercisable.

   The rights of the America Online series A-1 preferred stock as to dividends,
liquidation and voting, and in the event of mergers or consolidations, are
protected by customary antidilution provisions.

   MapQuest has not entered into a stockholder's rights agreement.

                STATEMENTS REGARDING FORWARD-LOOKING INFORMATION

   The Securities and Exchange Commission encourages companies to disclose
forward-looking information so that investors can better understand a company's
future prospects and make informed investment decisions. This proxy
statement/prospectus contains such "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. These
statements may be made directly in this proxy statement/prospectus referring to
America Online and MapQuest, and they may also be made a part of this proxy
statement/prospectus by reference to other documents filed with the Securities
and Exchange Commission by America Online and MapQuest, which is known as
"incorporation by reference." These statements may include statements regarding
the period following completion of the merger.

   Words such as "anticipate," "estimate," "expect," "project," "intend,"
"plan," "believe" and words and terms of similar substance used in connection
with any discussion of future operating or financial performance, or the merger
of America Online and MapQuest, or the proposed merger between America Online
and Time Warner, identify forward-looking statements. All forward-looking
statements are management's present expectations of future events and are
subject to a number of factors and uncertainties that could cause actual
results to differ materially from those described in the forward-looking
statements. In addition to the risks related to their businesses, the following
factors relating to the mergers, among others, could cause actual results to
differ from those described in the forward-looking statements: the inability to
obtain, or meet conditions imposed for, governmental approvals of the mergers,
the failure of the MapQuest stockholders to approve our merger, the failure of
the America Online or Time Warner stockholders to approve the proposed Time
Warner merger, the costs related to the mergers, the inability to further
identify, develop and achieve commercial success for new products and services
and access and distribution technologies, increased competition and its effects
on pricing, spending, third-party relationships and the subscriber base and
revenues, the inability to establish and maintain relationship with commerce,
advertising, marketing, technology and content providers, the risk of accepting
warrants in certain agreements and the risks of new and changing regulation in
the United States and internationally. Stockholders are cautioned not to place
undue reliance on the forward-looking statements, which speak only of the date
of this proxy statement/prospectus or the date of the document incorporated by
reference in this proxy statement/prospectus. Neither America Online nor
MapQuest is under any obligation, and each expressly disclaims any obligation,
to update or alter any forward-looking statements, whether as a result of new
information, future events or otherwise.

   For additional information about factors that could cause actual results to
differ materially from those described in the forward-looking statements,
please see the quarterly reports on Form 10-Q and the annual reports on Form
10-K that America Online and MapQuest have filed with the Securities and
Exchange Commission.

   All subsequent forward-looking statements attributable to America Online or
MapQuest or any person acting on their behalf are expressly qualified in their
entirety by the cautionary statements contained or referred to in this section.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors
MapQuest.com, Inc.

   We have audited the accompanying balance sheets of MapQuest.com, Inc. as of
December 31, 1998 and 1999, and the related statements of operations, changes
in redeemable preferred stock, common stock, and other stockholders' equity
(deficit), and cash flows for each of the three years in the period ended
December 31, 1999. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of MapQuest.com, Inc. at
December 31, 1998 and 1999, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1999, in
conformity with accounting principles generally accepted in the United States.

                         NOTES TO FINANCIAL STATEMENTS

                               December 31, 1999

1. Business and Accounting Policies

 Business

   In January 1999, GeoSystems Global Corporation changed its name to
MapQuest.com, Inc. MapQuest.com, Inc. ("MapQuest" or the "Company") is an
online provider of mapping and destination information through its Website,
mapquest.com. MapQuest's proprietary integration and editing of geographic
databases enable it to provide comprehensive mapping solutions to businesses
and provide customized maps, destination information and driving directions to
consumers. Consumers can also purchase maps and cartography information from
MapQuest's MapStore located on mapquest.com. In 1999 MapQuest began to focus on
developing wireless and voice applications that allow MapQuest users to access
driving directions and find information about various points of interest.

   MapQuest is also a United States provider of traditional digital mapping
products and services to the educational, reference, directory, travel and
governmental markets. In addition, companies that incorporate call centers, CD-
ROMs or stand-alone driving direction kiosks into their information delivery
strategy require non-Internet customized mapping solutions. MapQuest has
developed its map-enabling software to promote the rapid development of mapping
applications in these environments.

 Revenue Recognition

   Contracts with businesses for Internet products and services are generally
entered into on an annual basis and consist of a one-time setup fee and annual
service or license fee. The one-time setup fee is based on costs incurred to
initially integrate the website connection and is recognized upon installation
of the connection. The remaining service or license fee is recognized ratably
over the contract period. Revenues recognized under this method are included in
the statements of operations as business revenues.

   Royalty revenues are recognized when earned based on the revenues generated
by the sale of a licensed product or based on the minimum royalty provisions in
the related contract. Revenues from the sale of licenses to its customers for
the use of MapQuest's geographic systems or products are generally recognized
upon delivery of the licensed systems or products if no significant obligations
exist. Revenues from maintenance or upgrade obligations are recognized ratably
over the obligation period. MapQuest's license agreements have terms generally
ranging from one to three years. Substantially all revenues recognized under
these methods are included in the statements of operations as business
revenues.

   Revenues from long-term fixed price contracts for the development of
customized geographic and cartographic data are recognized on the percentage of
completion method, measured by the percentage of labor hours incurred to date
to estimated total labor hours for each contract. Revenues recognized in excess
of amounts billed are classified as contract work in progress. Amounts billed
to clients for contracts in excess of revenues recognized to date are
classified as advance billings on contracts. Revenues recognized under this
method are included in the statements of operations as digital mapping
revenues.

   Advertising revenue is recognized ratably over the period in which the
advertisements are displayed, provided that no significant obligations remain
and collection of the resulting receivable is probable. The duration of
MapQuest's advertising arrangements may range from one month to one year.
MapQuest may guarantee its advertisers a pre-set level of impressions during
the contract period. To the extent minimum guaranteed impression levels are not
met ratably over the contract period, MapQuest defers recognition of the
corresponding pro-rata portion of the revenues relating to such unfulfilled
obligations until the guaranteed impression levels are achieved. Revenues
recognized under this method are included in the statements of operations as
consumer revenues.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                               December 31, 1999


   Barter revenues are recognized in connection with agreements in which
MapQuest receives advertising or other goods and services in exchange for
content or advertising on mapquest.com. Barter transactions are recorded at the
lower of estimated fair value of the goods or services received or the
estimated fair value of the content or advertisements given. Barter
transactions accounted for approximately 1%, 2% and 2% of revenues during 1997,
1998 and 1999, respectively. Revenues recognized under this method are included
in the statements of operations as consumer revenues.

   Revenues from all other services provided and products sold or licensed are
recognized when the services are rendered or delivery of the product is made
and no significant MapQuest obligations remain outstanding. Revenues recognized
under this method are included in the statements of operations as digital
mapping or business revenues.

 Product Development

   Product development expenses in the accompanying statements of operations
include the costs to develop new products and services and to modify existing
products and services, including software and data. These costs consist
primarily of salaries for product development personnel and related expenses,
contract labor expense, and consulting fees. Statement of Financial Accounting
Standards ("SFAS") No. 86, "Accounting for the Costs of Computer Software to be
Sold, Leased or Otherwise Marketed," requires capitalization of certain
software development costs subsequent to the establishment of technological
feasibility. Based upon MapQuest's product development process, technological
feasibility is established upon completion of a working model. Costs incurred
by MapQuest between completion of the working model and the point at which the
product is ready for general release were insignificant in 1997 and 1998. In
1999, MapQuest capitalized $298,178 of software development costs.

 Statements of Cash Flows

   For purposes of the statements of cash flows, MapQuest considers all cash
and highly liquid investments with a maturity of three months or less when
purchased to be cash equivalents.

 Investments

   The Company invests certain of its excess cash in debt instruments of the
U.S. Government and its agencies, and of high quality corporate issuers. All
highly liquid instruments with original maturities greater than three months
but less than twelve months when purchased are considered short-term
investments. In accordance with SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," MapQuest classifies its investment
securities as available-for-sale. Unrealized holding gains and losses at
December 31, 1999 were not significant.

 Fair Values of Financial Instruments

   The carrying amounts of cash and cash equivalents, short-term investments,
notes receivable and notes payable approximate fair value because of the short-
term maturity of these instruments.

 Inventories

   Inventories are carried at the lower of cost or market using the first-in,
first-out (FIFO) method.

                               December 31, 1999

 Property and Equipment

   Property and equipment consisting primarily of computer hardware are stated
at historical cost. Depreciation is computed principally using the straight-
line method over the estimated useful life of assets ranging from 3 to 5 years.

 Goodwill

   Goodwill, principally from the acquisition of Maryland Cartographics, Inc.
in July 1994, represents the excess of cost over fair value of net assets
acquired and is being amortized over 10 years using the straight-line method.

 Accounting for Stock-Based Compensation

   In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation." SFAS No. 123 prescribes accounting and reporting standards for
all stock-based compensation plans, including employee stock options,
restricted stock, employee stock purchase plans and stock appreciation rights.
SFAS No. 123 requires compensation expense to be recorded (i) using the new
fair value method or (ii) using existing accounting rules prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees", ("APB 25") and related interpretations with pro forma disclosure of
what net income and earnings per share would have been had the Company adopted
the fair value method. The Company accounts for its stock-based compensation
plans in accordance with the provisions of APB 25.

 Advertising Costs

   Advertising costs are expensed as incurred. Advertising costs for 1997, 1998
and 1999 amounted to approximately $779,000, $742,000 and $4,563,710,
respectively, and include barter advertising costs for 1997, 1998 and 1999 of
$148,000, $538,000 and $777,000, respectively.

 Investment in Joint Venture

   The Company's 50 percent-owned joint venture, Donnelly Spatial Data LP, is
accounted for by the equity method. The joint venture is engaged in providing,
among other things, highway trip routing products and services. Income from the
joint venture is included as a component of Other Income and was approximately
$256,000 in 1997, $292,000 in 1998 and $241,000 in 1999.

 Use of Estimates

   The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                               December 31, 1999

 General and Administrative Expenses

   The Company recorded $1.7 million of non-recurring expenses in the fourth
quarter of 1999. These consisted of charges related to transaction costs
associated with potential acquisitions that were not consummated, and expenses
associated with certain third-party patented technology used by mapquest.com.

 New Accounting Pronouncements

   In December 1999, the Securities and Exchange Commission released Staff
Accounting Bulletin ("SAB") No. 101 "Revenue Recognition in Financial
Statements." SAB 101, as amended, provides additional guidance in applying
generally accepted accounting principles for revenue recognition in financial
statements. MapQuest plans to adopt any changes it believes to be mandated by
the SAB no later than the second quarter of 2000. MapQuest does not expect the
SAB to have a material impact on the financial position or results of
operations of MapQuest.

2. Merger with America Online, Inc.

   On December 22, 1999, the Company announced that it will be acquired by
America Online in an all-stock transaction pursuant to a merger agreement
executed on December 21, 1999. Shareholders of MapQuest will receive 0.31558
shares of America Online common stock for each share of MapQuest common stock.
The transaction is expected to close in the spring of 2000, subject to various
conditions including customary regulatory approvals and the approval of
MapQuest shareholders. The transaction will be accounted for as a pooling-of-
interests by America Online.

3. Debt Arrangements

   MapQuest had a $5,000,000 secured line of credit with a financial
institution payable on demand. Borrowings under the line of credit were limited
to 80% of MapQuest's qualified accounts receivable that were within 90 days of
invoice. Under the agreement, MapQuest could choose an interest rate based on
the following options: prime rate, a fixed rate as offered by the bank from
time to time for varying periods up to 180 days, or at the LIBOR rate plus
1.75% for periods of 30, 60, 90 or 180 days. No amount was drawn on the line at
December 31, 1998 or 1999. As of December 31, 1999, the line of credit had
expired.

   MapQuest entered into a promissory note during 1997. Terms of repayment
required thirty consecutive monthly payments of principal and interest.
Interest on the outstanding principal was fixed at a rate of 9%. This note was
satisfied during 1999.

4. Inventories

   Inventories are comprised of the following:

5. Preferred Stock and Stockholders' Equity

 Restated Certificates of Incorporation

   On July 17, 1997, MapQuest filed a Restated Certificate of Incorporation
with the State of Delaware in conjunction with the purchase and sale of Series
C Preferred Stock. The Restated Certificate of Incorporation authorized
MapQuest to issue 35,000,000 shares, of which 20,000,000 shares were designated
Common Stock and 15,000,000 shares were designated Preferred Stock. Of the
Preferred Stock, 6,550,000 shares were designated Series A Preferred, 2,000,000
shares were designated Series B Preferred, 3,800,000 shares were designated
Series C Preferred and 2,650,000 shares were undesignated as to series.

   On April 27, 1999, MapQuest filed a Restated Certificate of Incorporation
with the State of Delaware in conjunction with the Company's initial public
offering. The Restated Certificate of Incorporation authorizes MapQuest to
issue 105,000,000 shares, of which 100,000,000 shares are designated Common
Stock and 5,000,000 shares are undesignated Preferred Stock. This Restated
Certificate of Incorporation became effective upon the effectiveness of
MapQuest's registration statement in connection with its initial public
offering.

 Initial Public Offering

   During April 1999, the Board of Directors and the stockholders authorized a
2.7-for-1 split of MapQuest's common stock. In addition, the Board of Directors
and the stockholders authorized and approved the amendment and restatement of
MapQuest's Certificate of Incorporation such that MapQuest has the authority to
issue an aggregate of 105,000,000 shares of capital stock, consisting of
100,000,000 shares of common stock, par value $0.001 per share and 5,000,000
shares of preferred stock, par value $0.01 per share. This amended and restated
Certificate of Incorporation became effective upon the effectiveness of
MapQuest's registration statement for its initial public offering. All
references to common shares, per common share, and par value per common share
in the financial statements give retroactive effect to the common stock split
and change in par value per common share. Upon the effectiveness of MapQuest's
registration statement for its initial public offering, MapQuest adopted the
1999 Stock Plan pursuant to which 3,645,000 shares of common stock were
reserved for future issuance and established an employee stock purchase plan
under which a total of 1,755,000 shares of common stock could be made available
for sale. In connection with the merger with America Online, Inc. (see Note 2),
MapQuest is precluded from implementing the employee stock purchase plan.

   In May 1999, MapQuest completed an initial public offering of 4,600,000
shares of its common stock at a public offering price of $15 per share, which
generated approximately $61.6 million in net proceeds to MapQuest.

   Upon the closing of MapQuest's initial public offering in May 1999, all of
the outstanding shares of MapQuest's Series A and Series C Preferred Stock were
converted into 27,122,455 shares of common stock and all of the outstanding

a redemption feature was added and the issued and outstanding shares were
reclassified outside of stockholders' equity. Each share of Series A Preferred
Stock automatically converted into 2.7 shares of Common Stock upon the closing
of MapQuest's initial public offering during May 1999. Each share of Series A
Preferred Stock issued and outstanding had a number of votes equal to the
number of shares into which such share of Series A Preferred Stock were then

holders under certain circumstances. No dividends could be paid on the Series A
Preferred Stock unless MapQuest had fulfilled its dividend obligations on the
Series B Preferred Stock and Series C Preferred Stock. The Series A Preferred
Stock had an annual cash dividend rate of $.075 per share when and as declared
by the Board of Directors.

   Pursuant to the terms of the stock purchase agreement dated October 31,
1994, MapQuest sold 215,000 shares of its Series A Preferred Stock at a

aggregate purchase price of $215,000 was paid $127,500 in cash and $87,500 in
notes due October 31, 1999. The notes bear interest at a rate of 7.5%
compounded annually. Payments are due annually in an amount that is the lesser
of one-fifth of the principal balance or 50% of any bonus to which each
employee is entitled. The notes are secured by the shares purchased, with
shares released to the extent each note is paid. At December 31, 1998 and 1999,
outstanding notes receivable in conjunction with this stock purchase were
$35,200 and $0, respectively.

October 31, 1994, the Company sold 35,000 shares of its Series A Preferred
Stock at a purchase price of $1 per share to a member of MapQuest's then
existing management. The aggregate purchase price of $35,000 was paid $3,500 in
cash and $31,500 in a note due October 31, 2000. The note bears interest at a
rate of 7.5% compounded annually. The repayment terms were modified pursuant to
a severance agreement in 1997. The payment of the note, inclusive of interest,
is due on the earlier of September 30, 2000 or the date on which the severed
employee transfers all shares of the employee's Series A Preferred Stock or
common stock into which they are converted. The note is secured by the shares

to December 31, 1997 and $.39975 per share with respect to dividends payable
after December 31, 1997. The dividend could be paid in cash or a combination of
cash and additional shares of Series B Preferred Stock; however, at least
13.33% of the dividend payable in any period on or prior to December 31, 1997
was payable in cash. As of December 31, 1998, there were no dividends in

$516,299 and $327,484, respectively, on Series B Preferred Stock. These
dividends included cash dividends of $74,506, $0 and $0, and stock dividends of
$484,306, $516,299 and $327,484, during 1997, 1998 and 1999, respectively. The
stock dividends were based on the issuance of additional shares of Series B

   During June 1998, MapQuest accelerated the vesting and extended the exercise
period of options in connection with a severance agreement for the former
President and recorded compensation expense of $38,000.

   The consummation of the initial public offering during May 1999 resulted in
the acceleration of the vesting of 1,484,954 options to purchase common stock
and the announcement of the merger with America Online, Inc., on December 22,
1999 resulted in the acceleration of the vesting of 2,273,051 of options to
purchase common stock in accordance with the provisions of the 1995 Stock
Option Plan and option grant agreements.

statement. No factor for volatility has been reflected in the option pricing
calculation for grants made prior to MapQuest's initial public offering. For
grants made subsequent to the initial public offering, MapQuest used a
volatility factor of 65.3%. The fair value of the options was estimated at date
of grant using a Black-Scholes option pricing model with the following
additional assumptions:

</TABLE>

   The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because MapQuest stock options have characteristics significantly different
from those of traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its stock options.

   For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. MapQuest's
pro forma information is as follows:

8. Income Taxes

   No provision for federal income taxes has been recorded as MapQuest has
incurred net operating losses during 1997, 1998 and 1999. A provision of less
than $1,000 has been recorded during 1999 for state income taxes.

   The tax effects of temporary differences and net operating loss and credit
carryforwards that give rise to MapQuest's deferred tax assets and liabilities
are as follows:

</TABLE>

   Due to the uncertainty of the realization of the deferred tax assets, a
valuation allowance has been provided. The valuation allowance was increased by
$2,618,565, $1,374,256 and $11,829,457 for the years ended December 31, 1997,
1998 and 1999, respectively.

   Of the total valuation allowance, $6,358,308 was the result of the exercise
of nonqualified stock options during 1999. The tax effect of these transactions
for the Company is a compensation deduction for tax purposes totaling the
difference between the exercise price and the fair value of the shares on the
date of exercise. The exercise of the nonqualified options gave rise to an
additional permanent tax deduction of approximately $17,152,000 for the year
ended December 31, 1999 included as part of the net operating loss
carryforward. In the future, any realized benefit of this amount will be
credited to additional paid-in capital and not the statement of operations.

   As of December 31, 1999, MapQuest has net operating loss carryforwards of
approximately $44,324,000, which expire between 2009 and 2019, and research and
development tax credit carryforwards of approximately $768,000, which expire
between 2010 and 2014 for federal tax purposes. The utilization of

$10,300,000 of such net operating loss carryforwards is subject to an annual
limitation of approximately $1,300,000, pursuant to Section 382 of the Internal
Revenue Code.

9. Segment Information

   MapQuest has two reportable segments: MapQuest Business/Consumer and Digital
Mapping Services. The MapQuest Business/Consumer segment provides products and
services to address the web-based destination information needs of both
businesses and consumers. Business and Consumer revenues and costs are combined
for this segment because a significant portion of the costs, primarily
compensation for operations personnel and related operations costs, are common
to both Business and Consumer revenues and are not allocated. The Digital
Mapping Services segment provides non-internet mapping products and services to
the education, reference, directory, travel and governmental markets as well as
providing customized mapping solutions to various other customers. Revenues are
derived principally from the United States.

   The accounting policies of the segments are the same as those described in
the summary of significant accounting policies. MapQuest evaluates performance
based on gross profit and does not allocate assets to the reportable segments
since management does not evaluate segment performance based on asset
information and common assets are used in the segments. Accordingly,
depreciation expense is not included in the information set forth below.

   MapQuest's reportable segments are strategic business units that offer
different products and services. They are managed separately because each
business requires different technology and marketing strategies.

contribution up to 3% of their salary. The expense incurred related to this
plan was $209,235, $189,512 and $297,143 during the years ended December 31,
1997, 1998 and 1999, respectively.

12. Related Party Transactions

   MapQuest paid a management fee of $75,000 to a stockholder during 1997. In

the $75,000 annual management fee arrangement was terminated effective July 17,
1997. MapQuest incurred rent expense of $35,591 and $16,597 related to leases

                               December 31, 1999


   MapQuest has a commitment to purchase minimum amounts of advertising
pursuant to an advertising agreement for $3,500,000 and $4,500,000 in 2000 and
2001, respectively.

  Contingencies

   Pursuant to an indemnity obligation, the Company defended Moore U.S.A.,
Inc., in a legal proceeding filed by Mark Tornetta on December 14, 1998 in the
United States District Court for the Eastern District of Pennsylvania. Mr.
Tornetta alleged that Moore U.S.A., Inc. infringed his patent describing a
specific method for searching real estate properties. This case was dismissed
without prejudice on April 30, 1999.

   Rand McNally has written a letter to National Geographic claiming that
National Geographic's laminated maps infringe upon one of its patents. The
Company has agreed to take responsibility pursuant to its indemnification
obligations and believes that this claim will be settled for approximately
$10,000.

   The Company has also been approached by Unisys concerning a license under
U.S. Patent No. 4,558,302, which covers certain data compression technology
commonly referred to as the Lempel-Zev-Welch or ALZW@algorithm. Unisys and the
Company are presently engaged in negotiations concerning a possible settlement.
Unisys has not filed a lawsuit, although it has suggested the possibility of
litigation to enforce the "302 patent if negotiations are unsuccessful. The
Company believes the ultimate resolution of this matter will not have a
material adverse effect on the Company's financial position, results of
operations, or liquidity. Under the terms of the merger agreement, as described
in Note 2, the Company may not settle certain claims without America Online's
consent.

   Universal Map Enterprises, Inc. filed a lawsuit against MapQuest and America
Online in the United States District Court in the Western District of New York.
In that lawsuit, Universal Map Enterprises alleges claims against the Company
for breach of contract, conversion and specific performance, and against
America Online for tortious interference with business arrangements, in
connection with an alleged agreement to sell the Company's online electronic
commerce website, MapStore.com, to Universal Map. Since the commencement of the
action, Universal Map has subsequently agreed to dismiss America Online from
the action without prejudice. Universal Map is seeking to recover $1,000,000 in
damages and/or specific performance of the alleged agreement, plus costs and
fees. The Company and Universal Map have entered into a stipulation whereby the
Company has agreed not to frustrate the ability of Universal Map to enforce a
judgment for specific performance against the Company if so rendered. On
February 18, 2000, Universal Map filed a motion for summary judgment with the
court seeking summary disposition of its claims prior to discovery and trial.
MapQuest's opposition to that motion is set to be filed with the court. The
Company denies liability and intends to vigorously contest the motion and
defend the action. Management does not expect the claim will have a material
adverse effect on MapQuest's financial position, results of operations, or
liquidity.

   MapQuest periodically receives notices of claims arising out of the normal
course of business. Management is not aware of any notices of claims that would
have a material adverse effect on MapQuest's financial position, results of
operations, or liquidity.

              NOTES TO UNAUDITED INTERIM FINANCIAL STATEMENTS

                              March 31, 2000

1. Merger with America Online, Inc.

   On December 22, 1999, the Company announced that it will be acquired by
America Online, Inc. in an all-stock transaction pursuant to a merger agreement
executed on December 21, 1999. Shareholders of MapQuest will receive 0.31558
shares of America Online common stock for each share of MapQuest common stock.
The transaction is expected to close in mid-2000, subject to various conditions
including customary regulatory approvals and the approval of MapQuest
shareholders. The transaction will be accounted for as a pooling-of-interests
by America Online.

2. Basis of Presentation

   The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting only of
normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three-month period ended March 31,
2000 are not necessarily indicative of the results that may be expected for the
year ended December 31, 2000.

   For further information, refer to the financial statements and footnotes
thereto for the year ended December 31, 1999 included elsewhere in this proxy
statement/prospectus.

3. Stockholders' Equity

   During April 1999, the Board of Directors and the stockholders authorized a
2.7 for 1 split of MapQuest's common stock. In addition, the Board of Directors
and the stockholders authorized and approved the amendment and restatement of
MapQuest's Certificate of Incorporation such that MapQuest has the authority to
issue an aggregate of 105,000,000 shares of capital stock, consisting of
100,000,000 shares of common stock, par value $0.001 per share and 5,000,000
shares of preferred stock, par value $0.01 per share. This amended and restated
Certificate of Incorporation became effective upon the effectiveness of
MapQuest's registration statement for its initial public offering. All
references to common shares, per common share, and par value per common share
in the financial statements for the periods prior to the initial public
offering in May 1999 give retroactive effect to the common stock split and
change in par value per common share. Upon the effectiveness of MapQuest's
registration statement for its initial public offering, MapQuest adopted the
1999 Stock Plan, pursuant to which 3,645,000 shares of common stock were
reserved for future issuance, and established an employee stock purchase plan
under which a total of 1,755,000 shares of common stock could be made available
for sale. In connection with the merger with America Online, Inc., MapQuest is
precluded from implementing the employee stock purchase plan.

   In May 1999, MapQuest completed an initial public offering of 4,600,000
shares of its common stock at a public offering price of $15 per share, which
generated approximately $61.6 million in net proceeds to MapQuest.

   Upon the closing of MapQuest's initial public offering in May 1999, all of
the outstanding shares of MapQuest's Series A and Series C Preferred Stock were
converted into 27,122,455 shares of common stock and all of the outstanding
shares of MapQuest's Series B Preferred Stock were redeemed for approximately
$8.7 million.

                            MAPQUEST.COM, INC.

       NOTES TO UNAUDITED INTERIM FINANCIAL STATEMENTS--(Continued)

                              March 31, 2000

   During June 1999, in connection with MapQuest's initial public offering, the
underwriters of the offering exercised an over-allotment option for 597,990
shares of MapQuest's common stock at the initial public offering price of $15
per share, which generated approximately $8.3 million in net proceeds to
MapQuest.

4. Investments

   The Company invests certain of its excess cash in debt instruments of the
U.S. Government and its agencies, and of high-quality corporate issuers. All
highly liquid instruments with an original maturity of three months or less
when purchased are considered cash equivalents; those with original maturities
greater than three months but less than twelve months when purchased are
considered short-term investments. In accordance with Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities," MapQuest classifies its investment securities as available-
for-sale. Unrealized holding gains and losses at March 31, 2000 were not
significant.

5. Inventories

   Inventories are comprised of the following:

   On December 21, 1999, MapQuest issued to America Online, Inc. an option and
reserved common stock in conjunction with the merger agreement for 3,571,661
shares at an exercise price of $27.00 per share. These options have been
excluded from the diluted per share computations as they are antidilutive.

7. Segment Information

   MapQuest has two reportable segments: MapQuest Business/Consumer and Digital
Mapping Services. The MapQuest Business/Consumer segment provides products and
services to address the web-based destination information needs of both
businesses and consumers. Business and Consumer revenues and costs are combined
for this segment because a significant portion of the costs, primarily
compensation for operations personnel and related operations costs, are common
to both Business and Consumer revenues and are not allocated. The Digital
Mapping Services segment provides non-Internet mapping products and services to
the education, reference, directory, travel and governmental markets as well as
providing customized mapping solutions to various other customers. Revenues are
derived principally from the United States.

   The accounting policies of the segments are the same as those described in
the summary of significant accounting policies in MapQuest's 1999 financial
statements included elsewhere in this proxy statement/ prospectus. MapQuest
evaluates performance based on gross profit and does not allocate assets to the
reportable segments since management does not evaluate segment performance
based on asset information and common assets are used in the segments.

   MapQuest's reportable segments are strategic business units that offer
different products and services. They are managed separately because each
business requires different technology and marketing strategies.

       NOTES TO UNAUDITED INTERIM FINANCIAL STATEMENTS--(Continued)

                              March 31, 2000

8. Contingent Matters

   MapQuest has been approached by Unisys Corporation ("Unisys") concerning a
license under U.S. Patent No. 4,558,302, which covers certain data compression
technology commonly referred to as the Lempel-Zev-Welch or ALZW@algorithm.
Unisys and MapQuest are presently engaged in negotiations concerning a possible
settlement. Unisys has not filed a lawsuit, although it has suggested the
possibility of litigation to enforce the "302 patent if negotiations are
unsuccessful. The Company believes the ultimate resolution of this matter will
not have a material adverse effect on the Company's financial position, results
of operations, or liquidity. Under the terms of MapQuest's merger agreement
with America Online entered into on December 21, 1999, MapQuest may not settle
certain claims without America Online's consent.

   Universal Map Enterprises, Inc. filed a lawsuit against MapQuest and America
Online in the United States District Court in the Western District of New York.
In that lawsuit, Universal Map Enterprises alleges claims against MapQuest for
breach of contract, conversion and specific performance, and against America
Online for tortious interference with business arrangements, in connection with
an alleged agreement to sell MapQuest's online electronic commerce website,
MapStore.com, to Universal Map. Since the commencement of the action, Universal
Map has subsequently agreed to dismiss America Online from the action without
prejudice. Universal Map is seeking to recover $1,000,000 in damages and/or
specific performance of the alleged agreement, plus costs and fees. MapQuest
and Universal Map have entered into a stipulation whereby MapQuest has agreed
not to frustrate the ability of Universal Map to enforce a judgment for
specific performance against MapQuest if so rendered. On February 18, 2000,
Universal Map filed a motion for summary judgment with the court seeking
summary disposition of its claims prior to discovery and trial. MapQuest's
opposition to that motion is set to be filed with the court. MapQuest denies
liability and intends to vigorously contest the motion and defend the action.
Management does not expect the claim will have a material adverse effect on
MapQuest's financial position, results of operations, or liquidity.

   On April 6, 2000, Furman Roth, Inc. filed a lawsuit against MapQuest in the
Supreme Court of the State of New York, County of New York. In the lawsuit,
Furman Roth alleges claims against MapQuest for breach of contract, fraud,
quantum meruit and unjust enrichment in connection with alleged services
rendered with respect to certain placement of advertising by MapQuest. Furman
Roth is seeking to recover $1,575,000 in damages, plus unspecified punitive
damages. MapQuest denies liability and intends vigorously to defend against the
complaint. Management does not expect the claim will have a material adverse
effect on MapQuest's financial position, results of operations, or liquidity.

   MapQuest periodically receives notices of claims arising out of the normal
course of business. Management is not aware of any notices of claims that would
have a material adverse effect on MapQuest's financial position, results of
operations, or liquidity.

9. New Accounting Pronouncements

   In December 1999, the Securities and Exchange Commission released Staff
Accounting Bulletin ("SAB") No. 101 "Revenue Recognition in Financial
Statements." SAB 101, as amended, provides additional guidance in applying
generally accepted accounting principles for revenue recognition in financial
statements. MapQuest plans to adopt any changes it believes to be mandated by
the SAB no later than the second quarter of 2000. MapQuest does not expect the
SAB to have a material impact on the reported financial position or results of
operations of MapQuest.

   AGREEMENT AND PLAN OF MERGER, dated as of December 21, 1999, as amended by
Amendment No. 1, dated as of February 10, 2000 (the "Agreement"), among AMERICA
ONLINE, INC., a Delaware corporation ("Parent"), MQ ACQUISITION, INC., a
Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"),
and MAPQUEST.COM, INC., a Delaware corporation (the "Company").

   WHEREAS, the Boards of Directors of Parent, Merger Sub and the Company have
each determined that it is in the best interests of their respective
Stockholders for Parent to acquire the Company upon the terms and subject to
the conditions set forth herein;

   WHEREAS, in furtherance of such acquisition, the Boards of Directors of
Parent, Merger Sub and the Company have each approved the merger (the "Merger")
of Merger Sub with and into the Company, in accordance with the General
Corporation Law of the State of Delaware (the "DGCL") and subject to the
conditions set forth herein, which Merger will result in, among other things,
the Company becoming a wholly owned subsidiary of Parent;

   WHEREAS, as a condition to the willingness of, and an inducement to, Parent
and Merger Sub to enter into this Agreement, contemporaneously with the
execution and delivery of this Agreement, certain holders of Company Common
Stock (as defined herein), are entering into an agreement dated as of the date
hereof (the "Stockholders Agreement") in the form of Exhibit A attached hereto,
providing for certain actions relating to the transactions contemplated by this
Agreement;

   WHEREAS, as a condition to the willingness of, and an inducement to, Parent
and Merger Sub to enter into this Agreement, contemporaneously with the
execution and delivery of this Agreement, the Company is entering into a Stock
Option Agreement dated as of the date hereof (the "Option Agreement") in the
form of Exhibit B attached hereto, granting Parent an irrevocable option to
purchase up to that number of shares of Company Common Stock as shall represent
10% (by voting power) of the total outstanding Company Common Stock, on the
terms and subject to the conditions set forth therein;

   WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a tax-free reorganization within the meaning of Section 368(a)
of the Internal Revenue Code of 1986, as amended (the "Code"); and

   WHEREAS, for accounting purposes, it is intended that the Merger shall
qualify for "pooling-of-interests" treatment.

   NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, Parent, Merger Sub and the Company hereby
agree as follows:

                                   ARTICLE I

                                   THE MERGER

                                      A-1
<PAGE>

   1.2. Effective Time. As promptly as practicable after the satisfaction or,
to the extent permitted hereunder, waiver of the conditions set forth in
Article VI, the parties hereto shall cause the Merger to be consummated by
filing a certificate of merger (the "Certificate of Merger") with the Secretary
of State of the State of Delaware, in such form as required by and executed in
accordance with the relevant provisions of the DGCL (the date and time of such
filing, or such later date and time as may be specified in the Certificate of
Merger by mutual agreement of Parent, Merger Sub and the Company, being the
"Effective Time").

   1.3 Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in the applicable provisions of the DGCL, including
Section 259 thereof. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time, all the assets, property, rights,

shall vest in the Surviving Corporation, and all debts, liabilities and duties
of the Company and Merger Sub shall become the debts, liabilities and duties of
the Surviving Corporation.

   1.4 Certification of Incorporation; Bylaws. Unless otherwise determined by
Parent prior to the Effective Time, at the Effective Time and without any
further action on the part of the parties hereto, (a) the Certificate of
Incorporation of Merger Sub shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended as provided by the DGCL;
provided that Article First of the Certificate of Incorporation of Merger Sub
shall be amended to read in its entirety as follows: "The name of the
corporation is MapQuest.com, Inc. and (b) the Bylaws of Merger Sub shall be the
Bylaws of the Surviving Corporation until thereafter amended as provided by the
DGCL.

   1.5 Directors and Officers. The directors of Merger Sub immediately prior to
the Effective Time shall be the initial directors of the Surviving Corporation,
each to hold office in accordance with the Certificate of Incorporation and the
Bylaws of the Surviving Corporation until their respective successors are duly
elected or appointed and qualified or until their earlier death, resignation or
removal in accordance with the Surviving Corporation's Certificate of
Incorporation and Bylaws. The officers of the Company immediately prior to the
Effective Time shall be the initial officers of the Surviving Corporation.

   1.6 Conversion of Company Common Stock, Etc. At the Effective Time, by
virtue of the Merger and without any action on the part of the parties hereto
or the holders of the following securities:

   (a) Subject to the provisions of this Article I, each share of Common Stock,
par value $.001 per share, of the Company (the "Company Common Stock") issued
and outstanding immediately prior to the Effective Time (other than any shares
of the Company Common Stock to be canceled pursuant to Section 1.7 and subject
to Section 1.10 and Section 1.1) will be converted automatically into the right
to receive 0.31558 of a fully paid and nonassessable share (the "Exchange
Ratio") of the Common Stock, par value $0.01 per share (the "Parent Common
Stock"), of Parent (and a related portion of a Parent Right in accordance with
Section 1.6(b) hereof)(the "Merger Consideration").

   (b) Each share of the Parent Common Stock to be issued upon conversion of
the Company Common Stock in accordance with Section 1.6(a) shall include the
corresponding percentage of a right (a "Parent Right") to purchase shares of
Series A-1 Junior Participating Preferred Stock, $.01 par value, of Parent
pursuant to the Rights Agreement dated as of May 12, 1998, as amended (the
"Parent Rights Agreement"), between Parent and BankBoston, N.A., as Rights
Agent. Prior to the Distribution Date (as defined in the Parent Rights
Agreement), all references in this Agreement to the Parent Common Stock shall
be deemed to include Parent Rights.

   (c) Each share of the Company Common Stock issued and outstanding
immediately prior to the Effective Time shall automatically be redeemed and
canceled and shall cease to exist, and each holder of a certificate
representing any such Company Common Stock shall cease to have any rights with
respect thereto, except the right to receive the Merger Consideration and any
cash in lieu of fractional shares of Parent Common Stock to be issued or paid
in consideration therefor upon surrender of such certificate in accordance with
Section 1.12 hereof, without interest.

                                      A-2
<PAGE>

   1.7 Cancellation of Treasury Stock and Parent-Owned Stock.

   (a) Each share of the Company Common Stock held in the treasury of the
Company, if any, and each share of Company Common Stock, if any, owned by
Parent or Merger Sub, in each case immediately prior to the Effective Time,
shall be canceled and extinguished without any conversion thereof and no
payment or distribution shall be made with respect thereto.

   1.8 Stock Options and Warrants.

   (a) At the Effective Time, all options to purchase Company Common Stock then
outstanding under the Company's 1995 Stock Option Plan, as amended (the "1995
Plan"), the Company's 1999 Stock Plan, as amended (the "1999 Plan" and,
together with the 1995 Plan, the "Option Plans") by virtue of the Merger and
without any action on the part of the holder thereof, shall be assumed by
Parent in accordance with Section 5.5.

   (b) The Company and its Board of Directors shall promptly take all actions
necessary to ensure that following the Effective Time no holder of any options
or other rights pursuant to, nor any participant in or party to, the Option
Plans or any other Employee Plan (as defined herein) or other plan, program,
arrangement, agreement or other commitment providing for the issuance or grant
of any interest in respect of the capital stock of the Company or any
Subsidiary of the Company will have any rights thereunder to acquire equity
securities, or any right to payment in respect of the equity securities, of
Parent, the Company, or the Surviving Corporation or any of their Subsidiaries,
except as provided herein.

   1.9 Capital Stock of Merger Sub. Each share of Common Stock, par value $0.01
per share, of Merger Sub (the "Merger Sub Common Stock") issued and outstanding
immediately prior to the Effective Time shall be automatically converted into
one validly issued, fully paid and nonassessable share of common stock of the
Surviving Corporation and shall thereafter constitute all of the issued and
outstanding capital stock of the Surviving Corporation. Each stock certificate
of Merger Sub evidencing ownership of any shares of Merger Sub Common Stock
shall continue to evidence ownership of such shares of capital stock of the
Surviving Corporation.

   1.10 Adjustments to Exchange Ratio. Without limiting any other provision of
this Agreement, the Exchange Ratio shall be adjusted to reflect fully the
effect of any stock split, reverse split, stock dividend (including any
dividend or distribution of securities convertible into Parent Common Stock or
Company Common Stock), reorganization, recapitalization or other like change
with respect to Parent Common Stock or Company Common Stock occurring after the
date hereof and prior to the Effective Time.

   1.11 Fractional Shares. No certificates or scrip representing fractional
shares of Parent Common Stock shall be issued in connection with the Merger,
and such fractional interests will not entitle the owner thereof to any rights
of a Stockholder of Parent. In lieu thereof, each holder of shares of Company
Common Stock exchanged pursuant to Section 1.6 or of options or warrants
exchanged pursuant to Section 1.8(b) who would otherwise be entitled to a
fraction of a share of Parent Common Stock (after aggregating all fractional
shares of Parent Common Stock to have been otherwise received by such holder)
shall receive from Parent an amount of cash (rounded down to the nearest whole
cent and without interest) equal to the product of such fractional part of a
share of Parent Common Stock multiplied by the average closing price per share
of Parent Common Stock (rounded to the nearest cent) on the New York Stock
Exchange, Inc. (the "NYSE") (as reported in the Wall Street Journal, or, if not
reported therein, any other authoritative source selected by Parent) for the 20
trading days ending on the third trading day immediately prior to (and
excluding the date of) the Effective Time.

   1.12 Surrender of Certificates.

   (a) Exchange Agent. Prior to the Effective Time, Parent shall designate a
bank or trust company to act as the Exchange Agent in the Merger.

   (b) Parent to Provide Common Stock. When and as needed, Parent shall make
available to the Exchange Agent for exchange in accordance with this Article I,
through such reasonable procedures as Parent may adopt, sufficient shares of
Parent Common Stock to be exchanged pursuant to Section 1.6.

                                      A-3
<PAGE>

   (c) Exchange Procedures. Promptly after the Effective Time, the Surviving
Corporation shall cause to be mailed to each holder of record of a certificate
or certificates (the "Certificates") that represented as of the Effective Time
outstanding shares of Company Common Stock to be exchanged pursuant to Section
1.6, a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
delivery of the Certificates to the Exchange Agent and shall be in such form
and have such other provisions as Parent may reasonably specify) and
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Parent Common Stock. Upon surrender of
a Certificate to the Exchange Agent, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions
thereto, and such other documents as may be required pursuant to such
instructions, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing the number of whole shares of
Parent Common Stock and payment in lieu of fractional shares which such holder
has the right to receive pursuant to Sections 1.6 and 1.11, after giving effect
to any required (as defined herein) Tax withholdings, and the Certificate so
surrendered shall forthwith be canceled. At any time following 6 months after
the Effective Time, all or any number of shares of Parent Common Stock (and any
or all cash payable in lieu of fractional shares of Parent Common Stock)
deposited with or made available to the Exchange Agent pursuant to Section
1.12(b), which remain undistributed to the holders of the Certificates
representing shares of Company Common Stock, shall be delivered to Parent upon
demand, and thereafter such holders of unexchanged shares of Company Common
Stock shall be entitled to look only to Parent (subject to abandoned property,
escheat or other similar laws) only as general creditors thereof with respect
to the shares of Parent Common Stock for payment upon due surrender of their
Certificates.

   (d) Distributions With Respect to Unexchanged Shares. No dividends or other
distributions declared or made after the Effective Time with respect to shares
of Parent Common Stock with a record date after the Effective Time will be paid
to the holder of any unsurrendered Certificate with respect to the whole shares
of Parent Common Stock represented thereby until the holder of record of such
Certificate shall surrender such Certificate. Subject to applicable law,
following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, at the time of such surrender,
the amount of dividends or other distributions with a record date after the
Effective Time and payable between the Effective Time and the time of such
surrender with respect to such whole shares of Parent Common Stock.

   (e) Transfers of Ownership. If any certificate for shares of Parent Common
Stock is to be issued in a name other than the name in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that (i) the Certificate so surrendered will be properly
endorsed and otherwise in proper form for transfer and that the Person
requesting such exchange will have paid any transfer or other Taxes required by
reason of the issuance of a certificate for shares of Parent Common Stock in a
name other than the name of the registered holder of the Certificate
surrendered or (ii) established to the satisfaction of Parent, or any agent
designated by Parent, that such Tax has been paid or is not applicable.

   (f) No Liability. Notwithstanding anything to the contrary in this
Agreement, none of the Exchange Agent, Parent, the Merger Sub or the Surviving
Corporation shall be liable to a holder of a Certificate for any Parent Common
Stock (and any cash payable for fractional shares of Parent Common Stock or any
other amount due, if any) that was properly delivered to a public official
pursuant to any applicable abandoned property, escheat or similar Law.

   (g) Withholding of Tax. Parent or the Exchange Agent will be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Company Common Stock such amounts as Parent (or any
Affiliate thereof) or the Exchange Agent shall determine in good faith they are
required to deduct and withhold with respect to the making of such payment
under the Code, or any provision of federal, state, local or foreign Tax Law.
To the extent that amounts are so withheld by Parent or the Exchange Agent,
such withheld amounts will be treated for all purposes of this Agreement as
having been paid to the holder of the Company Common Stock in respect of whom
such deduction and withholding were made by Parent.

                                      A-4
<PAGE>

   1.13 Further Ownership Rights in Company Common Stock. All shares of Parent
Common Stock issued upon the surrender for exchange of Company Common Stock in
accordance with the terms of this Article I (including any cash paid in respect
thereof) shall be deemed to have been issued in full satisfaction of all rights
pertaining to such Company Common Stock. At the Effective Time, the stock
transfer books of the Company shall be closed, and thereafter there shall be no
further registration of transfers of shares of Company Common Stock on the
records of the Surviving Corporation. From and after the Effective Time, the
holders of Certificates evidencing ownership of shares of Company Common Stock
outstanding shall cease to have any rights with respect to such shares of
Company Common Stock except as otherwise provided for herein. 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.

   1.14 Closing. Unless this Agreement shall have been terminated and the
transactions contemplated by this Agreement abandoned pursuant to the
provisions of Article VII, and subject to the provisions of Article VI, the
closing of the Merger (the "Closing") will take place at 10:00 a.m. (Eastern
time) on a date (the "Closing Date") to be mutually agreed upon by the parties,
which date shall be not later than the third Business Day after all the
conditions set forth in Article VI shall have been satisfied (or waived in
accordance with Section 7.5, to the extent the same may be waived), unless
another time and/or date is agreed by the parties hereto. The Closing shall
take place at the offices of Simpson Thacher & Bartlett, 425 Lexington Avenue,
New York, New York or such other place as the parties hereto otherwise agree.

   1.15 Lost, Stolen or Destroyed Certificates. In the event any Certificates
evidencing Company Common Stock shall have been lost, stolen or destroyed, the
Exchange Agent shall issue in exchange for such lost, stolen or destroyed
Certificates, upon the making of an affidavit of that fact by the holder
thereof, such shares of Parent Common Stock and cash for fractional shares, if
any, as may be required pursuant to Section 1.11; provided, however, that
Parent may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Parent or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

   1.16 Tax Consequences. For federal income tax purposes, the parties intend
that the Merger be treated as a reorganization within the meaning of Section
368(a) of the Code, and that this Agreement shall be, and is hereby, adopted as
a plan of reorganization for purposes of Section 368 of the Code. The parties
shall not take a position on any Tax Return (as defined herein) inconsistent
with this Section 1.16.

                                   ARTICLE II

licenses, permits, easements, consents, waivers, qualifications, certificates,
Orders (as defined herein) and approvals (collectively, "Approvals") necessary
to own, lease and operate its properties and to carry on its business as it is
now being conducted, except for such Approvals, the failure of the Company to
be in possession of could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect. The Company is duly qualified or
licensed as a foreign corporation to do business, and is in good standing, in
each jurisdiction where the character of the properties owned, leased or
operated by it or the nature of its activities makes such qualification or
licensing necessary, except where the failure to be so qualified could not,

Adverse Effect.


                                      A-5
<PAGE>

   (b) Each Subsidiary of the Company is a legal entity, duly organized,
validly existing and in good standing under the laws of its respective
jurisdiction of incorporation or organization and has all the requisite power

conducted. Each Subsidiary is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of the properties owned, leased or operated by it or the nature
of its activities makes such qualification or licensing necessary, except where
the failure to be so qualified could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

   (c) Section 2.1(c) of the Company Disclosure Schedule sets forth, as of the
date hereof, a true and complete list of all of the Company's directly and
indirectly owned Subsidiaries, together with the jurisdiction of incorporation
or organization of each Subsidiary and the percentage of each Subsidiary's
outstanding capital stock or other equity or other interest owned by the

   2.2 Certificate of Incorporation and Bylaws. The Company has heretofore
furnished to Parent a true and complete copy of each of its and each of its
Subsidiaries' Certificate of Incorporation and Bylaws or equivalent

and beneficially, by the Company or one of its direct or indirect Subsidiaries,
free and clear of all Liens whatsoever. Except as set forth in Section 2.3(b)

Schedule, as of the date hereof, there are no outstanding securities, options,
warrants, calls, rights, convertible or exchangeable securities, commitments,

   3.1 Organization and Qualification. Each of Parent and Merger Sub is a
corporation duly organized, validly existing and in good standing under the
laws of Delaware. Parent has all the requisite corporate power and authority,
and is in possession of all Approvals necessary to own, lease and operate its
properties and to carry on its business as it is now being conducted, except
where the failure to be so qualified, existing and in good standing or to have
such power, authority and Approvals could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. Each of
Parent and Merger Sub is duly qualified or licensed as a foreign corporation to
do business, and is in good standing, in each jurisdiction where the character
of the properties owned, leased or operated by it or the nature of its
activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that could
not, either individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. Merger Sub is a newly-formed single purpose entity
which has been formed solely for the

                                      A-21
<PAGE>

purposes of the Merger and will not carry on any business or engage in any
activities other than those reasonably related to the Merger.

   3.2 Capitalization.

   (a) As of the date hereof, the authorized capital stock of Parent consists
of (i) 6,000,000,000 shares of Parent Common Stock of which, as of December 21,
1999, approximately 2,270,342,472 shares were issued and outstanding, and (ii)
5,000,000 shares of preferred stock, par value $.01 per share, including
500,000 reserved for issuance under the Parent Rights Agreement, of which none
are issued or outstanding. All of the outstanding shares of Parent Common Stock
are, and all shares to be issued as part of the Merger Consideration will be,
when issued in accordance with the terms hereof, duly authorized, validly
issued, fully paid and nonassessable.

   (b) As of the date hereof, the authorized capital stock of Merger Sub
consists of 1,000 shares of Merger Sub Common Stock, of which 1,000 shares of
Merger Sub Common Stock are outstanding. All of the outstanding shares of
Merger Sub Common Stock are owned by Parent.

   3.3 Authority; Enforceability. Each of Parent and Merger Sub has all
requisite corporate power and authority to execute and deliver this Agreement
and each instrument required hereby to be executed and delivered by it at the
Closing, to perform its obligations hereunder and thereunder and to consummate
the transactions contemplated hereby and thereby. The execution and delivery by
each of Parent and Merger Sub of this Agreement and each instrument required
hereby to be executed and delivered by Parent and Merger Sub at the Closing and
the performance of their respective obligations hereunder and thereunder have
been duly and validly authorized by the Board of Directors of each of Parent
and Merger Sub and by Parent as the sole Stockholder of Merger Sub. Except for
filing of the Certificate of Merger, no other corporate proceedings on the part
of Parent or Merger Sub are necessary to authorize the consummation of the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by each of Parent and Merger Sub and, assuming due authorization,
execution and delivery hereof by the Company, constitutes a legal, valid and
binding obligation of each of Parent and Merger Sub, enforceable against each
of Parent and Merger Sub in accordance with its terms.

   3.4 No Conflict; Required Filings and Consents.

   (a) The execution and delivery by Parent and Merger Sub of this Agreement do
not, and the performance of this Agreement by Parent or Merger Sub shall not,
(i) conflict with or violate the Certificate of Incorporation or Bylaws of
Parent or the Certificate of Incorporation or Bylaws of Merger Sub, or (ii)
conflict with or violate any Law or Order in each case applicable to Parent or
Merger Sub or by which its or any of their respective properties is bound or
affected, except in the case of clause (ii) above, for any such conflicts or
violations that could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

   (b) The execution and delivery by Parent and Merger Sub of this Agreement do
not, and the performance by Parent and Merger Sub of this Agreement shall not,
require Parent or Merger Sub to obtain the Approval of, observe any waiting
period imposed by, or make any filing with or notification to, any Governmental
Authority, domestic or foreign, except for (A) compliance with applicable
requirements of the Securities Act, the Exchange Act, Blue Sky Laws, or the
pre-Merger notification requirements of the HSR Act or Foreign Competition
Laws, (B) the filing of the Certificate of Merger in accordance with Delaware
law, (C) the filing of a listing application or other documents as required by
the NYSE or (D) where the failure to obtain such Approvals, or to make such
filings or notifications, would not individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

   3.5 SEC Filings; Financial Statements.

   (a) Parent has filed all reports and documents required to be filed with the
SEC since January 1, 1999 (collectively, the "Parent SEC Reports") pursuant to
the federal securities Laws and Regulations of the SEC

                                      A-22
<PAGE>

promulgated thereunder, and all Parent SEC Reports have been filed in all
material respects on a timely basis. The Parent SEC Reports were prepared in
accordance, and complied as of their respective filing dates in all material
respects, with the requirements of the Exchange Act and the Regulations
promulgated thereunder and did not at the time they were filed (or if amended
or superseded by a filing prior to the date hereof, then on the date of such
filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

   (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in Parent SEC Reports (i) complied in all
material respects with applicable accounting requirements and the published
Regulations of the SEC with respect thereto, (ii) were prepared in accordance
with GAAP (except, in the case of unaudited statements, as permitted by Form
10-Q of the SEC) applied on a consistent basis throughout the periods involved
(except as may be expressly described in the notes thereto) and (iii) fairly
presents the consolidated financial position of Parent as at the respective
dates thereof and the consolidated results of its operations and cash flows for
the periods indicated, except that the unaudited interim financial statements
included in the Company's Form 10-Q reports were or are subject to normal and
recurring year-end adjustments that have not been and are not expected to be
material in amount to Parent.

   3.6 Absence of Litigation. Except as described in Section 3.6 of the Parent
Disclosure Schedule or expressly described in the Parent SEC Reports filed and
publicly available prior to the date hereof, there is no Litigation pending on
behalf of or against or, to the Knowledge of Parent, threatened against Parent,
any of its Subsidiaries, or any of their respective properties or rights,
before or subject to any Court or Governmental Authority which if adversely
determined would, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect. Neither Parent nor any of its Subsidiaries is
subject to any outstanding Litigation or Order which, individually or in the
aggregate, has had or could reasonably be expected to have a Material Adverse
Effect.

   3.7 Registration Statement; Proxy Statement/Prospectus. None of the
information supplied by Parent for inclusion in the Registration Statement
shall, at the time such document is filed, at the time amended or supplemented,
or at the time the Registration Statement is declared effective by the SEC,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. None of the information supplied by Parent for inclusion in the
Proxy Statement shall, on the date the Proxy Statement is first mailed to the
Stockholders of the Company, at the time of Company Stockholders' Meeting and
at the Effective Time, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not false or misleading. The Registration Statement will comply as to
form in all material respects with the provisions of the Securities Act.
Notwithstanding the foregoing, Parent makes no representation, warranty or
covenant with respect to any information supplied by the Company which is
contained in the Registration Statement or Proxy Statement.

   3.8 Pooling; Tax Matters. To the Knowledge of Parent, neither Parent and
Merger Sub nor any of their Affiliates has taken or agreed to take any action
or failed to take any action that would prevent (a) the Merger from being
treated for financial accounting purposes as a "pooling of interests" in
accordance with GAAP and the Regulations of the SEC or (b) the Merger from
constituting a reorganization within the meaning of Section 368(a) of the Code.

Representatives"), to directly or indirectly, (i) solicit, facilitate,

of any proposal or offer that constitutes or may constitute an Acquisition
Proposal (as defined herein) or (ii) participate or engage in any discussions
or negotiations with, or provide any information to or take any other action
with the intent to facilitate the efforts of, any Person concerning any

this Agreement, the term "Acquisition Proposal" shall mean any inquiry,
proposal or offer from any person (other than Parent, Merger Sub or any of
their Affiliates) relating to any merger, consolidation, recapitalization,
liquidation or other direct or indirect business combination, involving the
Company or any Material Subsidiary (as defined herein) or the issuance or
acquisition of shares of capital stock or other equity securities of the
Company or any Material Subsidiary representing 20% or more of the outstanding

Subsidiary, or the sale, lease, exchange, license (whether exclusive or not),

any significant portion of the business or other assets of the Company or any
Material Subsidiary, or any other transaction, the consummation of which could

the consummation of the transactions contemplated hereby or which would
reasonably be expected to diminish significantly the benefits to Parent or its
Affiliates of the transactions contemplated hereby. The Company shall
immediately cease and cause to be terminated, and shall cause its Subsidiaries
and all Company Representatives to immediately terminate and cause to be
terminated, all existing discussions or negotiations with any Persons conducted
heretofore with respect to, or that could reasonably be expected to lead to, an
Acquisition Proposal. The Company shall promptly notify each Company
Representative of its obligations under this Section 4.2. Without limiting the
foregoing, it is agreed that any violation of the restrictions set forth above
by any Affiliate or Subsidiary of the Company or any Company Representative,
whether or not such Person is purporting to act on behalf of the Company, shall
be deemed to be a breach of this Section 4.2(a) by the Company.

   (b) Notwithstanding the foregoing, the Company may participate in
discussions or negotiations with, or furnish information with respect to the
Company pursuant to a confidentiality agreement with terms no less

                                      A-26
<PAGE>

favorable to the Company than those in effect between the Company and Parent
to, any Person if and only if (x) such Person has submitted an unsolicited bona
fide written Acquisition Proposal to the Company's Board of Directors, (y)
neither the Company nor any of the Company Representatives shall have violated
Section 4.2(a) and (z) the Board of Directors of the Company (i) determines by
a majority vote in its good faith judgment, after consultation with outside
counsel, that taking such action is required to satisfy the fiduciary duties of
such Board under applicable Law and (ii) provides prior written notice to
Parent of its decision to so participate or furnish.

   (c) Except as set forth in the following sentence, neither the Board of
Directors of the Company nor any committee thereof shall (1) approve or
recommend, or propose to approve or recommend, any Acquisition Proposal other
than the Merger, (2) withdraw or modify or propose to withdraw or modify in a
manner adverse to Parent or Merger Sub its approval or recommendation of the
Merger, this Agreement or the transactions contemplated hereby, (3) upon a
request by Parent to reaffirm its approval or recommendation of this Agreement
or the Merger, fail to do so within two Business Days after such request is
made, (4) approve, enter, or permit or cause the Company or any Material
Subsidiary to enter, into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement related to any Acquisition
Proposal, or (5) resolve or announce its intention to do any of the foregoing.
The immediately preceding sentence notwithstanding, in the event that prior to
the Company Stockholders' Meeting the Board of Directors of the Company
receives a Superior Proposal (as defined herein), the Board of Directors of the
Company may (i) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to Parent or Merger Sub its approval or recommendation of the
Merger, this Agreement or the transactions contemplated hereby, (ii) fail to
reaffirm its approval or recommendation of this Agreement or the Merger within
two Business Days after a request by Parent to do so, or (iii) resolve or
announce its intention to do any of the actions set forth in the preceding
clauses (i) or (ii), if (x) after consultation with outside counsel, such Board
determines by a majority vote of directors in their good faith judgment that
taking such action is required to satisfy the fiduciary duties of such Board
under applicable Law and (y) the Company furnishes Parent two Business Days'
prior written notice of the taking of such action (which notice shall include a
description of the material terms and conditions of the Superior Proposal and
identify the person making the same). For purposes of this Agreement, (A)
"Material Subsidiary" means any Subsidiary of the Company whose consolidated
revenues, net income or assets constitute 20% or more of the revenues, net
income or assets of the Company and its Subsidiaries taken as a whole, and (B)
the term "Superior Proposal" means any bona fide Acquisition Proposal to effect
a merger, consolidation or sale of all or substantially all of the assets or
capital stock of the Company which is on terms which the Board of Directors of
the Company determines by a majority vote of its directors in their good faith
judgment (based on the written opinion, with only customary qualifications, of
a financial advisor of nationally recognized reputation that the consideration
provided in such Acquisition Proposal likely exceeds the value of the
consideration provided for in the Merger), after taking into account all
relevant factors, including any conditions to such Acquisition Proposal, the
form of consideration contemplated by such Acquisition Proposal, the timing of
the closing thereof, the risk of nonconsummation, the ability of the Person
making the Acquisition Proposal to finance the transactions contemplated
thereby and any required filings or Approvals, to be more favorable to the
Stockholders of the Company than the Merger (or any revised proposal made by
Parent).

   (d) In addition to the other obligations of the Company set forth in this
Section 4.2, the Company shall immediately advise Parent orally and in writing
of any request for information with respect to any Acquisition Proposal, or any
inquiry with respect to or which could result in an Acquisition Proposal, the
material terms and conditions of such request, Acquisition Proposal or inquiry,
and the identity of the Person making the same. The Company shall inform Parent
on a prompt and current basis of the status and content of any discussions
regarding any Acquisition Proposal with a third party and as promptly as
practicable of any change in the price, structure or form of the consideration
or material terms of and conditions regarding any Acquisition Proposal or of
any other developments or circumstances which could reasonably be expected to
culminate in the taking of any of the actions referred to in Section 4.2(c).
Nothing contained in this Section 4.2(d) shall prevent the Board of Directors
of the Company from complying with Rule 14d-9 and Rule 14e-2 promulgated under
the Exchange Act.

Unless the Company shall have taken action permitted by the second sentence of
Section 4.2(c), the Company shall not file with or supplementally provide to
the SEC or mail to its Stockholders the Proxy Statement or any amendment or
supplement thereto without Parent's prior consent, which consent shall not be

participation in the preparation of the Proxy Statement and any amendment or
supplement thereto and shall consult with Parent and its advisors concerning
any comments from the SEC with respect thereto.

   (b) Parent shall prepare and file with the SEC a Registration Statement on
Form S-4, in which the Proxy Statement shall be included as a prospectus, and
the parties hereto shall use all reasonable efforts to have the Registration
Statement declared effective by the SEC as promptly as practicable after such
filing. Parent shall obtain and furnish the information required to be included
in the Registration Statement and, after consultation with the Company, respond
promptly to any comments made by the SEC with respect to the Registration
Statement.

   (c) The Proxy Statement shall include the recommendation of the Board of
Directors of the Company in favor of approval and adoption of this Agreement
and the Merger, except to the extent that the Company shall have withdrawn or
modified its recommendation of this Agreement or the Merger as permitted by
Section 4.2(c).

   (d) Parent and the Company shall, as promptly as practicable, make all
necessary filings with respect to the Merger under the Securities Act and the

   (e) Each party hereto agrees to furnish all information concerning itself as
may be reasonably required to prepare the Proxy Statement or Registration
Statement or to make such filings pursuant to Section 5.1(d). Each party hereto

respect.

   5.2 Meeting of Company's Stockholders. The Company shall promptly after the
date hereof take all action necessary in accordance with the DGCL and its
Certificate of Incorporation and Bylaws to duly call, give notice of and
(unless Parent requests otherwise) hold the Company Stockholders Meeting as
soon as practicable following the date upon which the Registration Statement
becomes effective and shall consult with Parent in connection therewith. Once
the Company Stockholders' Meeting has been called and noticed, the Company
shall not postpone or adjourn (other than for the absence of a quorum and then
only to a future date specified by Parent) the Company Stockholders' Meeting
without the consent of Parent. The Board of Directors of the Company has
declared that this Agreement is advisable and, subject to Section 4.2(c), shall
recommend that this Agreement and the transactions contemplated hereby be
approved and authorized by the Stockholders of the Company and include in the
Registration Statement and Proxy Statement a copy of such recommendations;
provided, however, that the Board of Directors of the Company shall submit this
Agreement to the Stockholders of the Company whether or not the Board of
Directors of the Company at any time

4.2(c). The Company shall solicit from its Stockholders proxies in favor of the
Merger and shall take all other action necessary or advisable to secure the
vote or consent of its Stockholders to authorize and approve the Merger.
Without limiting the generality of the foregoing, (i) the Company agrees that

contemplated hereby or might adversely affect the Company or Parent or any of
Parent's Affiliates, including its Subsidiaries. Neither party hereto will take

agreements thereunder and other relevant documentation immediately prior to the
Effective Time, except that such Outstanding Employee Option will be
exercisable solely 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

                                      A-30
<PAGE>

purchasable under such Outstanding Employee 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 the per-share exercise price
for the shares of Parent Common Stock issuable upon exercise of such assumed
Outstanding Employee Option will be equal to the quotient determined by
dividing the exercise price per share of Company Common Stock at which such
Outstanding Employee Option was exercisable immediately prior to the Effective
Time by the Exchange Ratio, and rounding the resulting exercise price up to the
nearest whole cent.

   (b) Parent shall reserve for issuance a sufficient number of shares of
Parent Common Stock for delivery upon exercise of Outstanding Employee Options
assumed by Parent under this Agreement. Parent shall file as soon as
practicable after the Effective Date a registration statement on Form S-8 under
the Securities Act covering the shares of Parent Common Stock issuable upon the
exercise of the Outstanding Employee Options assumed by Parent pursuant to
Section 5.5(a), and shall use its reasonable efforts to cause such registration
statement to become effective as soon thereafter as practicable and to maintain
such registration in effect until the exercise or expiration of such assumed
Outstanding Employee Options.

   (c) The vesting of each Outstanding Employee Option shall not accelerate as
a result of, or in connection with, the transactions contemplated hereby,
except to the extent required by the existing terms of the 1995 Plan or option
agreement pursuant to which it was granted. In addition, the Company shall
ensure that no discretion is exercised by the Board of Directors or any
committee thereof or any other body or Person so as to cause the vesting of any
Outstanding Employee Option or any other warrant or right to acquire shares of
Company Common Stock to accelerate.

   (d) On and after the date hereof, the Company shall ensure that no offerings
are made with respect to the Purchase Plan, that no employee payroll deductions
are allowed under the Purchase Plan, and that no options to purchase Company
Common Stock shall be granted (or to be granted) under the Purchase Plan.

   (a) Parent agrees that individuals who are employed by the Company or any
Subsidiary of the Company immediately prior to the Effective Time shall become
employees of the Surviving Corporation or one of its Subsidiaries upon the
Effective Time (each such employee, a "Company Employee"); provided, however,
that this Section 5.6(a) shall not be construed to limit the ability of the
Company or any of its Subsidiaries to terminate the employment of any Company
Employee at any time.

   (b) After the Effective Time and on a schedule determined by Parent in
connection with its integration  of its business with that of the Company, the
Company Employees shall be eligible to participate in the employee benefit
plans of Parent to the same extent as any similarly situated and geographically
located employee of Parent. The Company Employees will be allowed credit for
their service with the Company and its Subsidiaries for purposes of vesting,
calculating the number of vacation days to which such employees are entitled,
subject to a maximum of five incremental days of vacation, and participation
only (and not for entitlement (except as provided with respect to vacation) or
benefit accrual purposes), with respect to the employee benefit plans in which
such Company Employees are allowed by Parent to participate following the
Effective Time.

   (c) If requested by Parent in writing prior to the Effective Time, the
Company shall cause to be adopted prior to the Effective Time resolutions of
the Company's Board of Directors to cease all contributions to the Company's
Retirement Savings Plan (the "401(k) Plan"), and to terminate the 401(k) Plan,
immediately prior to the Effective Time. Such resolutions shall provide (to the
extent required under Section 411 of the Code) that all participants shall be
fully vested in their account balances under the 401(k) Plan. Such resolutions
shall also authorize distributions of 401(k) Plan balances to participants (to
the extent permitted under Section 401(k) (10) of the Code) as soon as
practicable following the Company's receipt from the Internal Revenue Service
of a favorable determination letter regarding the tax-qualified status of the
401(k) Plan following its termination.

                                      A-31

soon as practicable following their adoption by Company's Board of Directors
and shall fully comply with such resolutions.

being treated (i) for financial accounting purposes as a "pooling of interests"
under GAAP; it being understood and agreed that if the Company's Accountants
advise the Company in writing that such an action would not prevent the Merger
from being so treated, such action will be conclusively deemed not to
constitute a breach of this Section 5.7 or (ii) as a "reorganization withing

under GAAP; it being understood and agreed that if Ernst & Young LLP, Parent's
independent accountants ("Parent's Accountants"), advises Parent in writing
that such an action would not prevent the Merger from being so treated, such
action will be conclusively deemed not to constitute a breach of this Section
5.7; or (ii) as a "reorganization" within the meaning of Section 368 of the
Code.

   (d) Parent shall use its reasonable efforts to obtain an executed affiliate
pooling agreement containing substantially the substance of the second and
third paragraphs of the Company Affiliate Pooling Agreement from each of the
Persons identified in Section 5.7(d) of the Parent Disclosure Schedule

agreements in accordance with their terms in existence on the date hereof,
shall, with respect to any matter existing or occurring at or prior to the
Effective Time (including the

                                      A-33
<PAGE>

transactions contemplated by this Agreement), survive the Effective Time for a
period of not less than six years.

   (b) Parent shall cause to be maintained for a period of six years from the
Effective Time the Company's current directors and officers insurance policy
(the "Company's D&O Insurance") to the extent that it provides coverage for
events occurring prior to the Effective Time for all Persons who are directors
and officers of the Company on the date of this Agreement, so long as the
annual premium therefor would not be in excess of 150% of the last annual
premium paid prior to the date of this Agreement (such amount, the "Maximum

directors and officers insurance provides (or is amended to provide)
substantially similar coverage for events occurring prior to the Effective Time

cause to be obtained as much directors and officers insurance as can be
obtained for the remainder of such period for an annualized premium not in
excess of the Maximum Premium, on terms and conditions no less advantageous
than the Company's D&O Insurance. The Company represents to Parent that the
last annual premium paid prior to the date of this Agreement is not greater
than $500,000.

   (c) The provisions of this Section 5.13 are intended to be for the benefit
of, and shall be enforceable by, each Person entitled to indemnification
hereunder and the heirs and representatives of such Person.

   5.14 Stockholders Agreement. The Company shall use its reasonable best
efforts, on behalf of Parent and pursuant to the request of Parent, to cause
each Stockholder of the Company named on the signature pages to the
Stockholders Agreement to execute and deliver to Parent, concurrently with the

Common Stock and provide such documentation and do such other things as may be
necessary to effectuate the provisions of such Stockholders Agreement.

Time, providing for, among other things, release of the Company, Parent and the
Surviving Corporation and their respective Affiliates from any and all claims,
known and unknown, that such Person has or may have against such Persons
through the Effective Time.

to cause each of the Persons identified in Section 5.17 of the Parent
Disclosure Schedule to execute and deliver a written acknowledgment, in form
and substance satisfactory to Parent, acknowledging that the options to

deemed in each case to be followed by the words "without limitation." The word

substance of the transactions contemplated hereby is not affected in any manner
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that transactions contemplated hereby are fulfilled to the extent possible.

   8.7 Entire Agreement. This Agreement and the Related Agreements (including
all exhibits and schedules hereto and thereto) and other documents and

them, with respect to the subject matter hereof and thereof.

   8.8 Assignment. This Agreement shall not be assigned by operation of Law or
otherwise, except that Parent and Merger Sub may assign all or any of their
rights hereunder to any Affiliate, provided, that no such assignment shall
relieve the assigning party of its obligations hereunder.

solely to the benefit of each party hereto, and, except as set forth in Section

whatsoever under or by reason of this Agreement.

   8.10 Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or
delay on the part of any party hereto in the exercise of any right hereunder
will impair such right or be construed to be a waiver of, or acquiescence in,
any breach of any representation, warranty or agreement herein, nor will any
single or partial exercise of any such right preclude other or further exercise
thereof or of any other right. All rights and remedies existing under this
Agreement are cumulative to, and not exclusive to, and not exclusive of, any
rights or remedies otherwise available.

   8.11 Governing Law; Enforcement. This Agreement and the rights and duties of
the parties hereunder shall be governed by, and construed in accordance with,
the Law of the State of New York. The parties agree that irreparable damage

Related Agreement were not performed in accordance with their specific terms or
were otherwise breached. It is accordingly agreed that the parties shall be
entitled to an injunction or injunctions to prevent breaches of this Agreement
or any Related Agreement and to enforce specifically the terms and provisions

<PAGE>

transaction contemplated hereby or thereby, (b) agrees that it will not attempt

leave from any such court, (c) agrees that it will not bring any action
relating to this Agreement or any Related Agreement or any transaction
contemplated hereby or thereby in the Federal District Court for the Southern
District of New York and (d) waives any right to trial by jury with respect to
any action related to or arising out of this Agreement or Related Agreement or
any transaction contemplated hereby or thereby.

   8.12 Counterparts. This Agreement may be executed in one or more
counterparts, and by the different parties hereto in separate counterparts,
each of which when executed shall be deemed to be an original but all of which
taken together shall constitute one and the same agreement.

   STOCK OPTION AGREEMENT, dated as of December 21, 1999 (the "Agreement"),
between AMERICA ONLINE, INC., a Delaware corporation ("Parent"), and
MAPQUEST.COM, INC., a Delaware corporation (the "Company").

   WHEREAS, Parent, the Company and MQ Acquisition, Inc., a Delaware
corporation and a wholly owned subsidiary of Parent ("Merger Sub"), are,
concurrently with the execution and delivery of this Agreement, entering into
an Agreement and Plan of Merger, dated as of the date hereof (the "Merger
Agreement;" capitalized terms used without definition herein having the
meanings assigned to them in the Merger Agreement), pursuant to which the
Merger Sub will merger with and into the Company (the "Merger"); and

   WHEREAS, as a condition to their willingness to enter into the Merger
Agreement, Parent and Merger Sub have required that the Company agree, and
believing it to be in the best interests of the Company, the Company has
agreed, among other things, to grant to Parent the Option (as hereinafter
defined) to purchase shares of common stock, par value $.001 per share, of the
Company ("Company Common Stock") at a price per share equal to the Exercise
Price (as hereinafter defined).

   NOW THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, the parties hereto agree as follows:

                                   ARTICLE I

                           OPTION TO PURCHASE SHARES

   1.1 Grant of Option.

   (a) The Company hereby grants to Parent an irrevocable option to purchase,
in whole or in part, an aggregate of up to 3,571,661 duly authorized, validly
issued, fully paid and nonassessable shares of Company Common Stock
(representing 10% of the outstanding shares of Company Common Stock as of the
date hereof) on the terms and subject to the conditions set forth herein (the
"Option"); provided, however, that in no event shall the number of shares of
Company Common Stock for which this Option is exercisable exceed 10% of the
issued and outstanding shares of Company Common Stock at the time of exercise
without giving effect to the issuance of any Option Shares (as hereinafter
defined). The number of shares of Company Common Stock that may be received
upon the exercise of the Option and the Exercise Price are subject to
adjustment as herein set forth.

   (b) In the event that any additional shares of Company Common Stock are
issued or otherwise become outstanding after the date of this Agreement (other
than pursuant to this Agreement and other than pursuant to an event described
in Section 3.1 hereof), the number of shares of Company Common Stock subject to
the Option shall be increased so that, after such issuance, such number
together with any shares of Company Common Stock previously issued pursuant
hereto, equals 10% of the number of shares of Company Common Stock then issued
and outstanding without giving effect to any shares subject or issued pursuant
to the Option. Nothing contained in this Section 1.1(b) or elsewhere in this
Agreement shall be deemed to authorize the Company to breach any provision of
the Merger Agreement. As used herein, the term "Option Shares" means the shares
of Company Common Stock issuable pursuant to the Option, as the number of such
shares shall be adjusted pursuant to the terms hereof.

   1.2 Exercise of Option.

   (a) The Option may be exercised by Parent, in whole or in part, at any time,
or from time to time, commencing upon the Exercise Date and prior to the
Expiration Date. As used herein, the term "Exercise Date" means the date on
which Parent becomes entitled to receive the Termination Fee pursuant to
Section

                                      B-1
<PAGE>

7.3(b) of the Merger Agreement. As used herein, the term "Expiration Date"
means the first to occur prior to Parent's exercise of the option pursuant to
Section 1.2(b) of:

     (i) the Effective Time;

     (ii) written notice of termination of this Agreement by Parent to the
  Company;

     (iii) the termination of the Merger Agreement under circumstances where
  the Termination Fee could not become payable; or

     (iv) the date that is twelve months from the date of termination of the
  Merger Agreement.

Notwithstanding the termination of the Option, Parent shall be entitled to
purchase those Option Shares with respect to which it may have exercised the
Option in accordance with the terms hereof prior to the Expiration Date, and
the termination of the Option will not affect any rights hereunder which by
their terms do not terminate or expire prior to or at the Expiration Date.

   (b) In the event Parent wishes to exercise the Option, Parent shall send a
written notice to the Company of its intention to so exercise the Option (a
"Notice"), specifying the number of Option Shares to be purchased (and the
denominations of the certificates, if more than one), whether the aggregate
Exercise Price will be paid in cash or by surrendering a portion of the Option
in accordance with Section 1.3(b) or a combination thereof, and the place in
the United States, time and date of the closing of such purchase (the "Option
Closing;" and the date of such Closing, the "Option Closing Date"), which date
shall not be less than two Business Days nor more than ten Business Days from
the date on which a Notice is delivered; provided, that the Option Closing
shall be held only if (i) such purchase would not otherwise violate or cause
the violation of, any applicable material Law (including the HSR Act or the
rules of the National Association of Securities Dealers, Inc. (the "NASD")) and
(ii) no material Law or Order shall have been promulgated, enacted, entered
into, or enforced by any Court or Governmental Authority which prohibits
delivery of the Option Shares, whether temporary, preliminary or permanent;
provided, however, that the parties hereto shall use their reasonable best
efforts to (x) make all necessary filings and obtain all Approvals and to
comply with any such applicable Law and (y) have any such Order vacated or
reversed). In the event the Option Closing is delayed pursuant to clause (i) or
(ii) above, the Option Closing shall be within five business days following the
cessation of such restriction, violation, Law or Order, as the case may be;
provided, further, that, notwithstanding any prior Notice, Parent shall be
entitled to rescind such Notice and shall not be obligated to purchase any
Option Shares in connection with such exercise upon written notice to such
effect to the Company.

   (c) At any Option Closing, (i) the Company shall deliver to Parent all of
the Option Shares to be purchased by delivery of a certificate or certificates
evidencing such Option Shares in the denominations designated by Parent in the
Notice, and (ii) if the Option is exercised in part and/or surrendered in part
to pay the aggregate Exercise Price, the Company and Parent shall execute and
deliver an amendment to this Agreement reflecting the Option Shares for which
the Option has not been exercised and/or surrendered. If at the time of
issuance of any Option Shares pursuant to an exercise of all or part of the
Option hereunder, the Company shall have issued any rights or other securities
which are attached to or otherwise associated with the Company Common Stock,
then each Option Share issued pursuant to such exercise shall also represent
such rights or other securities with terms substantially the same as and at
least as favorable to Parent as are provided under any shareholder rights
agreement or similar agreement of the Company then in effect. At the Option
Closing, Parent shall pay to the Company by wire transfer of immediately
available funds to an account specified by the Company to Parent in writing at
least two Business Days prior to the Option Closing an amount equal to the
Exercise Price multiplied by the number of Option Shares to be purchased for
cash pursuant to this Article I; provided that the failure or refusal of the
Company to specify an account shall not affect the Company's obligation to
issue the Option Shares.

   (d) Upon the delivery by Parent to the Company of the Notice and the tender
of the applicable aggregate Exercise Price in immediately available funds or
the requisite portion of the Option, Parent shall be deemed to be the holder of
record of the Option Shares issuable upon such exercise, notwithstanding that
the stock

                                      B-2
<PAGE>

transfer books of the Company may then be closed, that certificates
representing such Option Shares may not then have been actually delivered to
Parent, or the Company may have failed or refused to take any action required
of it hereunder. The Company shall pay all expenses that may be payable in
connection with the preparation, issuance and delivery of stock certificates
under this Section 1.2 in the name of Parent or its designees, stock
certificates or a substitute option agreement in the name of the assignee,
transferee or designee of Parent and any filing fees and other expenses arising
from the performance of the transactions contemplated hereby, including
pursuant to the HSR Act.

   1.3 Payments.

   (a) The purchase and sale of the Option Shares pursuant to Section 1.2 of
this Agreement shall be at a purchase price equal to $27.00 per Share (as such
amount may be adjusted pursuant to the terms hereof, the "Exercise Price"),
payable at Parent's option in cash, by surrender of a portion of the Option in
accordance with Section 1.3(b), or a combination thereof.

   (b) Parent may elect to purchase Option Shares issuable, and pay some or all
of the aggregate Exercise Price payable, upon an exercise of the Option by
surrendering a portion of the Option with respect to such number of Option
Shares as is determined by dividing the (i) aggregate Exercise Price payable in
respect of the number of Option Shares being purchased in such manner by (ii)
the excess of the Fair Market Value (as defined below) per share of Company
Common Stock as of the last trading day preceding the Option Closing Date over
the per share Exercise Price. The "Fair Market Value" per share of Company
Common Stock shall be (i) if the Company Common Stock is listed on the Nasdaq
National Market ("NASDAQ"), national securities exchange or other nationally
recognized exchange or trading system as of the Option Closing Date, the
average of last reported sale prices per share of Company Common Stock thereon
for the 10 trading days immediately preceding the Option Closing Date, or (ii)
if the Company Common Stock is not listed on the NASDAQ, any national
securities exchange or other nationally recognized exchange or trading system
as of the Option Closing Date, the amount determined by a mutually acceptable
independent investment banking firm as the value per share the Company Common
Stock would have if publicly traded on a nationally recognized exchange or
trading system (assuming the absence of unusual market conditions and no
discount for minority interest, illiquidity or restrictions on transfer.

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

   2.1 Representations and Warranties of Parent. Parent hereby represents and
warrants to the Company that any Option Shares acquired by Parent upon exercise
of the Option will not be taken with a view to the public distribution thereof
and will not be transferred or otherwise disposed of except in a transaction
registered or exempt from registration under the Securities Act.

   2.2 Representations and Warranties of the Company. The Company hereby
represents and warrants to Parent as follows:

   (a) Due Authorization; Good Standing. The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby
(including the issuance and exercise of the Option) have been duly and validly
authorized by the Board of Directors of the Company and no other corporate
proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the transactions contemplated hereby. This Agreement
has been duly and validly executed and delivered by the Company and constitutes
a legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has all requisite corporate power and authority to execute and
deliver this Agreement.

                                      B-3
<PAGE>

   (b) Option Shares. The Company has taken all necessary corporate and other
action to authorize and reserve for issuance, and to permit it to issue, the
Option Shares and all additional shares or other securities which may be issued
pursuant to Section 3.1 upon exercise of the Option, and, at all times from the
date hereof until such time as the obligation to deliver Option Shares
hereunder terminates, will have reserved for issuance upon exercise of the
Option the Option Shares and such other additional shares or securities, if
any. All of the Option Shares and all additional shares or other securities or
property which may be issuable pursuant to Section 3.1, upon exercise of the
Option and issuance pursuant hereto, shall be duly authorized, validly issued,
fully paid and nonassessable, shall be delivered free and clear of all Liens of
any nature whatsoever, and shall not be subject to any preemptive or similar
right of any Person.

   (c) No Conflict; Required Filings and Consents. The execution and delivery
by the Company of this Agreement do not, and the performance of this Agreement
shall not, (i) conflict with or violate the Certificate of Incorporation or
Bylaws of the Company, (ii) conflict with or violate any Law or Order in each
case applicable to the Company or by which its properties or assets is bound or
affected, or (iii) result in any breach or violation 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 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 on any of
the properties or assets of the Company pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which the Company is a party or by which the
Company or its properties or assets is bound or affected, except in the case of
clause (ii) or (iii) above, for any such conflicts, breaches, violations,
defaults or other occurrences that would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. The execution and
delivery by the Company of this Agreement do not, and the performance of this
Agreement shall not, require the Company to, obtain any Approval of any Person
or Approval of, observe any waiting period imposed by, or make any filing with
or notification to, any Governmental Authority, domestic or foreign, except for
compliance with applicable requirements of the Securities Act, the Exchange Act
and Blue Sky Laws, the pre-Merger notification requirements of the HSR Act or
Foreign Competition Laws or where the failure to obtain such Approvals, or to
make such filings or notifications, could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

   (d) Takeover Laws. The Board of Directors of the Company has, prior to the
date hereof, approved this Agreement, the Merger Agreement and the Merger and
the other transactions contemplated hereby and thereby and such approval is
sufficient to render inapplicable to this Agreement, the Merger Agreement, the
Merger and any other transactions contemplated hereby and thereby, the
restrictions of Section 203 of the DGCL. No Delaware law or other takeover
statute or similar Law and no provision of the Certificate of Incorporation or
Bylaws of the Company or any Material Agreement to which the Company is a party
(a) would or would purport to impose restrictions which might adversely affect
or delay the consummation of the transactions contemplated by this Agreement,
or (b) as a result of the consummation of the transactions contemplated by this
Agreement, the Company or the Surviving Corporation by Parent or Merger Sub (i)
would or would purport to restrict or impair the ability of Parent to vote or
otherwise exercise the rights of a shareholder with respect to securities of
the Company or any of its Subsidiaries that may be acquired or controlled by
Parent or (ii) would or would purport to entitle any Person to acquire
securities of the Company.

                                  ARTICLE III

                   ADJUSTMENT UPON CHANGES IN CAPITALIZATION

   3.1 Adjustment Upon Changes in Capitalization. In addition to the adjustment
in the number of shares of Company Common Stock that may be purchased upon
exercise of the Option pursuant to Section 1.1 of this Agreement, the number of
shares of Company Common Stock that may be purchased upon the exercise of the
Option and the Exercise Price shall be subject to adjustment from time to time
as provided in this Section 3.1. In the event of any change in the number of
issued and outstanding shares of Company Common Stock by reason of any stock
dividend, split-up, merger, recapitalization, combination, conversion, exchange
of shares, spin-off or other change in the corporate or capital structure of
the Company which would have the effect of diluting or otherwise diminishing
Parent's rights hereunder, the number and kind of Option Shares or other
securities subject to the Option and the Exercise Price therefor shall be
appropriately adjusted so that Parent shall receive upon exercise (or, if such
a change occurs between exercise and Option Closing, upon Option Closing) of
the Option the number and kind of shares or other securities or property that
Parent would have received in respect of the Option Shares that Parent is
entitled to purchase upon exercise of the Option if the Option had been
exercised (or the purchase thereunder had been consummated, as the case may be)
immediately prior to such event or the record date for such event, as
applicable. The rights of Parent under this Section shall be in addition to,
and shall in no way limit, its rights against the Company for breach of any
provision of the Merger Agreement.

                                   ARTICLE IV

                              REGISTRATION RIGHTS

   4.1 Registration of Option Shares Under the Securities Act.

   (a) If requested by Parent at any time and from time to time after receipt
by Parent of Option Shares (the "Registration Period"), the Company shall use
its reasonable best efforts, as promptly as practicable, to effect the
registration under the Securities Act and any applicable state law (a "Demand
Registration") of such number of Option Shares owned by or issuable to Parent
in accordance with the method of sale or other disposition contemplated by
Parent, including a "shelf" registration statement under Rule 415 of the
Securities Act or any successor provision, and to obtain all consents or
waivers of other parties that are required therefor. Except with respect to
such a "shelf" registration, the Company shall keep such Demand Registration
effective for a period of not less than nine months, unless, in the written
opinion of counsel to the Company, which opinion shall be delivered to Parent
and which shall be satisfactory in form and substance to Parent and its
counsel, such registration under the Securities Act is not required in order to
lawfully sell and distribute such Option Shares in the manner contemplated by
Parent. The Company shall only have the obligation to effect four Demand
Registrations pursuant to this Section 4.1; provided, that only requests
relating to a registration statement that has become effective under the
Securities Act shall be counted for purposes of determining the number of
Demand Registrations made. The Company shall be entitled to postpone for up to
90 days from receipt of Parent's request for a Demand Registration the filing
of any registration statement in connection therewith if the Board of Directors
of the Company determines in its good faith reasonable judgment, that such
registration would materially interfere with or require premature disclosure
of, and have a material adverse effect on, any material acquisition,
reorganization or other transaction involving the Company or any other material
contract under active negotiation by the Company; provided, that the Company
shall not have postponed any Demand Registration pursuant to this sentence
during the twelve month period immediately preceding the date of delivery of
Parent's request for a Demand Registration.

   (b) If the Company effects a registration under the Securities Act of
Company Common Stock for its own account or for any other stockholders of the
Company (other than on Form S-4 or Form S-8, or any successor form), Parent
shall have the right to participate in such registration (an "Incidental
Registration" and, together with a Demand Registration, a "Registration");
provided, however, that, if the managing underwriters of such

                                      B-5
<PAGE>

offering advise the Company in writing that in their opinion the number of
shares of Company Common Stock requested to be included in such Incidental
Registration exceeds the number which can be sold in such offering, the Company
shall include therein (i) first all shares proposed to be included therein by
the Company and (ii) second the shares requested to be included therein by
Parent pro rata with the shares intended to be included therein by any other
stockholder of the Company. Participation by Parent in any Incidental
Registration shall not affect the obligation of the Company to effect Demand
Registrations under this Section 4.1. The Company may withdraw any registration
under the Securities Act that gives rise to an Incidental Registration without
the consent of Parent.

   (c) In connection with any Registration pursuant to this Section 4.1, (i)
the Company and Parent shall provide each other and any underwriter of the
offering with customary representations, warranties, covenants, indemnification
and contribution obligations in connection with such Registration, and (ii) the
Company shall use reasonable best efforts to cause any Option Shares included
in such Registration to be approved for listing on NASDAQ or any national
securities exchange upon which the Company's securities are then listed,
subject to official notice of issuance, which notice shall be given by the
Company upon issuance. The costs and expenses incurred by the Company in
connection with any Registration pursuant to this Section 4.1 (including any
fees related to Blue Sky qualifications and SEC filing fees) (the "Registration
Expenses") shall be borne by the Company, excluding legal fees of Parent's
counsel and underwriting discounts or commissions with respect to Option Shares
to be sold by Parent included in a Registration.

                                   ARTICLE V

                     REPURCHASE RIGHTS; SUBSTITUTE OPTIONS

   5.1 Repurchase Rights.

   (a) Subject to Section 6.1, at any time on or after the Exercise Date and
prior to the Expiration Date, Parent shall have the right (the "Repurchase
Right") to require the Company to repurchase from Parent (i) the Option or any
part thereof as Parent shall designate at a price (the "Option Repurchase
Price") equal to the amount, subject at the sole discretion of Parent to clause
(iii) of Section 6.1(a), by which (A) the Market/Offer Price (as defined below)
exceeds (B) the Exercise Price, multiplied by the number of Option Shares as to
which the Option is to be repurchased and (ii) such number of the Option Shares
as Parent shall designate at a price (the "Option Share Repurchase Price")
equal to the Market/Offer Price multiplied by the number of Option Shares so
designated. The term "Market/Offer Price" shall mean the highest of (i) the
highest price per share of Company Common Stock offered or paid in any
Acquisition Proposal or any acquisition by any Person or group, in a single
transaction or a series of related transactions, after the date hereof of 10%
or more of the outstanding shares of capital stock of the Company, (ii) the
highest closing price for shares of Company Common Stock during the 30 trading
days immediately preceding the date Parent gives the Repurchase Notice (as
hereinafter defined), or (iii) in the event of a sale of all or substantially
all of the Company's assets, the sum of the net price paid in such sale for
such assets plus the current market value of the remaining net assets of the
Company as determined by a nationally recognized investment banking firm
selected by Parent and reasonably acceptable to the Company, divided by the
number of shares of Company Common Stock issued and outstanding at the time of
such sale, which determination, absent manifest error, shall be conclusive for
all purposes of this Agreement. In determining the Market/Offer Price, the
value of consideration other than cash shall be determined by a nationally
recognized investment banking firm selected by Parent and reasonably acceptable
to the Company, which determination, absent manifest error, shall be conclusive
for all purposes of this Agreement.

   (b) Parent shall exercise its Repurchase Right by delivering to the Company
written notice (a "Repurchase Notice") stating that Parent elects to require
the Company to repurchase all or a portion of the Option and/or the Option
Shares as specified therein. The closing of the Repurchase Right (the
"Repurchase Closing") shall take place in the United States at the place, time
and date specified in the Repurchase Notice, which date shall not be less than
two business days nor more than ten business days from the date on which the

                                      B-6
<PAGE>

Repurchase Notice is delivered. At the Repurchase Closing, subject to the
receipt of a writing evidencing the surrender of the Option and/or certificates
representing Option Shares, as the case may be, the Company shall deliver to
Parent the Option Repurchase Price therefor or the Option Share Repurchase
Price therefor, as the case may be, or the portion thereof that the Company is
not then prohibited under applicable law and regulation from so delivering. At
the Repurchase Closing, (i) the Company shall pay to Parent the Option
Repurchase Price for the portion of the Option which is to be repurchased or
the Option Shares Repurchase Price for the number of Option Shares to be
repurchased, as the case may be, by wire transfer of immediately available
funds to an account specified by Parent at least 24 hours prior to the
Repurchase Closing and (ii) if the Option is repurchased only in part, the
Company and Parent shall execute and deliver an amendment to this Agreement
reflecting the Option Shares for which the Option is not being repurchased.

   (c) To the extent that the Company is prohibited under applicable law or
regulation from repurchasing the portion of the Option or the Option Shares
designated in such Repurchase Notice, the Company shall immediately so notify
Parent and thereafter deliver, from time to time, to Parent the portion of the
Option Repurchase Price and the Option Share Repurchase Price, respectively,
that it is no longer prohibited from delivering, within five business days
after the date on which the Company is no longer so prohibited; provided,
however, that if the Company at any time after delivery of a Repurchase Notice
is prohibited under applicable Law from delivering to Parent the full amount of
the Option Repurchase Price and the Option Share Repurchase Price for the
Option or Option Shares to be repurchased, respectively, Parent may rescind the
exercise of the Repurchase Right, whether in whole, in part or to the extent of
the prohibition, and, to the extent rescinded, no part of the amounts, terms or
the rights with respect to the Option or Repurchase Right shall be changed or
affected as if such Repurchase Right was not exercised.

   5.2 Substitute Option.

   (a) In the event that the Company enters into an agreement (i) to
consolidate with or merge into any person, other than Parent or any Subsidiary
of Parent (each an "Excluded Person"), and the Company is not the continuing or
surviving corporation of such consolidation or merger, (ii) to permit any
Person, other than an Excluded Person, to merge into the Company and the
Company shall be the continuing or surviving or acquiring corporation, but, in
connection with such merger, the then outstanding shares of Company Common
Stock shall be changed into or exchanged for stock or other securities of any
other Person or cash or any other property or the then outstanding shares of
Company Common Stock shall after such merger represent less than 50% of the
outstanding shares and share equivalents of the merged or acquiring company, or
(iii) to sell or otherwise transfer all or substantially all of its assets to
any Person, other than an Excluded Person, then, and in each such case, the
agreement governing such transaction shall make proper provision so that,
unless earlier exercised by Parent, the Option shall, upon the consummation of
any such transaction and upon the terms and conditions set forth herein, be
converted into, or exchanged for, an option (the "Substitute Option") for
Substitute Option Shares (as hereinafter defined), at the election of Parent,
of either (x) the Acquiring Corporation (as hereinafter defined) or (y) any
Person that controls the Acquiring Corporation.

   (b) The Substitute Option shall have the same terms as the Option; provided,
however, that if the terms of the Substitute Option cannot, because of
applicable Law, be the same as the Option, such terms shall be as similar as
possible and in no event less advantageous to Parent than the Option. The
issuer of the Substitute Option shall enter into an agreement with Parent in
substantially the same form and terms as this Agreement (including the terms of
this Article V) to memorialize the terms of the Substitute Option. The
Substitute Option shall be exercisable for such number of Substitute Option
Shares as is equal to the Market/Offer Price multiplied by the number of shares
of Company Common Stock for which the Option was exercisable immediately prior
to the event described in the first sentence of Section 5.2(a), divided by the
Average Price (as hereinafter defined). The exercise price of the Substitute
Option per Substitute Option Share shall then be equal to the Exercise Price
multiplied by a fraction, the numerator of which shall be the number of shares
of Company Common Stock for which the Option was exercisable immediately prior
to the event described in the first sentence of Section 5.2(a) and the
denominator of which shall be the number of Substitute Option Shares for which
the Substitute Option is exercisable.


                                      B-7
<PAGE>

   (c) In addition to any other restrictions or covenants, the Company agrees
that it shall not enter or agree to enter into any transaction described in
Section 5.2(a) unless the Acquiring Corporation and any Person that controls

subsections, Schedules or Exhibits, such reference shall be to a Section,
subsection, Schedule or Exhibit to this Agreement unless otherwise indicated.
The words "include," "includes" and "including" when used herein shall be
deemed in each case to be followed by the words "without limitation." The word

way the meaning or interpretation of this Agreement.


   6.7 Severability. If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of Law, or public
policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
adverse to any party. Upon such determination that any term or other provision

that transactions contemplated hereby are fulfilled to the extent possible.


   6.8  Entire Agreement; No Third Party Beneficiaries. This Agreement

the parties hereto any rights or remedies hereunder.

   6.9 Amendments; Assignment. This Agreement may not be amended except by
written agreement by all the parties. This Agreement shall be binding upon and
inure to the benefit of the parties and their respective successors and
permitted assigns. Neither this Agreement nor any of the rights, interests or
obligations under this Agreement shall be assigned, in whole or in part, by any
of the parties without the prior written consent of the other parties, and any
purported assignment without such consent shall be void; provided, that Parent
may assign its rights and obligations hereunder to any direct or indirect
wholly owned subsidiary of Parent without such consent.

   6.10 Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or
delay on the part of any party hereto in the exercise of any right hereunder
will impair such right or be construed to be a waiver of,

                                      B-10
<PAGE>

or acquiescence in, any breach of any representation, warranty or agreement
herein, nor will any single or partial exercise of any such right preclude
other or further exercise thereof or of any other right. All rights and
remedies existing under this Agreement are cumulative to, and not exclusive to,
and not exclusive of, any rights or remedies otherwise available.

   6.11 Governing Law; Enforcement. This Agreement and the rights and duties of
the parties hereunder shall be governed by, and construed in accordance with,
the Law of the State of New York. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached.
It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in the Federal District Court for
the Southern District of New York, this being in addition to any other remedy
to which they are entitled at law or in equity. In addition, each of the
parties hereto, (a) consents to submit itself to the personal jurisdiction of

any dispute arises out of this Agreement or any transaction contemplated
hereby, (b) agrees that it will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court, (c)
agrees that it will not bring any action relating to this Agreement or any
transaction contemplated hereby in any court other than the Federal District
Court for the Southern District of New York and (d) waives any right to trial
by jury with respect to any action related to or arising out of this Agreement
or any transaction contemplated hereby.

   6.12 Counterparts. This Agreement may be executed in one or more

   STOCKHOLDERS AGREEMENT, dated as of December 21, 1999 (this "Agreement"),
among AMERICA ONLINE, INC., a Delaware corporation ("Parent"), MQ ACQUISITION,
INC., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger

and, collectively, the "Stockholders").

   WHEREAS, Parent, Merger Sub and the Company are, concurrently with the
execution and delivery of this Agreement, entering into an Agreement and Plan
of Merger, dated as of the date hereof (the "Merger Agreement;" capitalized
terms used without definition herein having the meanings assigned to them in
the Merger Agreement), pursuant to which Merger Sub will merge with and into
the Company (the "Merger");

   WHEREAS, as of the date hereof, each Stockholder is the record and
beneficial owner of the number of shares of Company Common Stock set forth on
the signature page hereof beneath such Stockholder's name (with respect to each
Stockholder, such Stockholder's "Existing Shares" and, together with any shares
of Company Common Stock acquired after the date hereof, whether upon the
exercise of warrants, options, conversion of convertible securities or
otherwise, such Stockholder's "Shares") and the record and beneficial owner of
options or warrants to purchase the number of shares of Company Common Stock
set forth on the signature page hereof beneath such Stockholder's name;

   WHEREAS, as an inducement and a condition to entering into the Merger
Agreement, Parent and Merger Sub have required that the Stockholders agree, and
the Stockholders have agreed, to enter into this Agreement;

   WHEREAS, among other things, the Stockholders, Parent and Merger Sub desire
to set forth their agreement with respect to the voting of the Shares in
connection with the Merger, upon the terms and subject to the conditions set
forth herein.

   NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, the parties hereto agree as follows:

                                   ARTICLE I

                                     VOTING

   1.1 Agreement to Vote. Each Stockholder hereby agrees, severally and not
jointly, that it shall, and shall cause the holder of record on any applicable
record date to, from time to time, at the request of Parent, at any meeting
(whether annual or special and whether or not an adjourned or postponed
meeting) of stockholders of the Company, however called, or in connection with
any written consent of the holders of Company Common Stock, (a) if a meeting is
held, appear at such meeting or otherwise cause the Shares to be counted as
present thereat for purposes of establishing a quorum, and (b) vote or consent
(or cause to be voted or consented), in person or by proxy, all Shares, and any
other voting securities of the Company (whether acquired heretofore or
hereafter) that are beneficially owned or held of record by such Stockholder or
as to which such Stockholder has, directly or indirectly, the right to vote or
direct the voting, in favor of the approval and adoption of the Merger
Agreement, the Merger and any action required in furtherance thereof.

   1.2 Grant of Proxy. In furtherance and not in limitation of the foregoing,
each Stockholder hereby grants to, and appoints, Parent and each of J. Michael
Kelly and Paul T. Cappuccio in their respective capacities as officers of
Parent, and any individual who shall hereafter succeed to any such officer of
Parent, and any other designee of Parent, each of them individually, its
irrevocable proxy and attorney-in-fact (with full power of substitution and
resubstitution) to vote the Shares as indicated in this Article I. Each
Stockholder intends this proxy to be irrevocable and coupled with an interest
and will take such further action and execute

                                      C-1
<PAGE>

such other instruments as may be necessary to effectuate the intent of this
proxy. Each Stockholder hereby revokes any and all previous proxies with
respect to such Stockholder's Shares or any other voting securities of the
Company that relate to the approval of the Merger Agreement.

   1.3 No Ownership Interest. Nothing contained in this Agreement shall be
deemed to vest in Parent any direct or indirect ownership or incidence of
ownership of or with respect to any Shares. All rights, ownership and economic
benefits of and relating to the Shares shall remain vested in and belong to the
Stockholders, and Parent shall have no authority to manage, direct,
superintend, restrict, regulate, govern, or administer any of the policies or
operations of the Company or exercise any power or authority to direct the
Stockholders in the voting of any of the Shares, except as otherwise provided
herein, or in the performance of the Stockholders' duties or responsibilities
as stockholders of the Company.

   1.4 Evaluation of Investment. Each Stockholder, by reason of its knowledge
and experience in financial and business matters, believes itself capable of
evaluating the merits and risks of the investment in shares of Parent Common
Stock contemplated by the Merger Agreement.

   1.5 Documents Delivered. Each Stockholder acknowledges receipt of copies of
the following documents: (a) the Merger Agreement and all exhibits and
schedules thereto, (b) the Option Agreement, (c) the Distribution Agreement,
dated as of the date hereof, between Parent and the Company, (d) Parent's
Annual Report on Form 10-K for the fiscal year ended June 30, 1999, (e)
Parent's Proxy Statement dated September 22, 1999, and (f) each report filed
with the SEC by Parent on Forms 8-K and 10-Q since June 30, 1999. Each
Stockholder also acknowledges that such Stockholder possesses all the
information relating to the Company which such Stockholder deems relevant or
material to such Stockholder's investment in Parent Common Stock should the
Merger be consummated and its entering into this Agreement.

   1.6 No Inconsistent Agreements. Each Stockholder hereby covenants and agrees
that, except as contemplated by this Agreement and the Merger Agreement, the
Stockholder (a) has not entered, and shall not enter at any time while this
Agreement remains in effect, into any voting agreement or voting trust with
respect to the Shares and (b) has not granted, and shall not grant at any time
while this Agreement remains in effect, a proxy or power of attorney with
respect to the Shares, in either case, which is inconsistent with such
Stockholder's obligations pursuant to this Agreement.

acceleration) under, any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, guarantee, other evidence of indebtedness, lease,

Shares and at all times during the term hereof and on the Closing Date will
have good and marketable title to its Shares, free and clear of all Liens, and,

therefor pursuant to the Merger Agreement, good and marketable title thereto,
free and clear of all Liens (other than any arising as a result of actions
taken or omitted by Merger Sub), will pass to Merger Sub.

   2.4 No Finder's Fees. Except as previously disclosed to Parent in writing,
no broker, investment banker, financial advisor or other Person is entitled to

   4.5 Interpretation. When a reference is made in this Agreement to Sections,
subsections, Schedules or Exhibits, such reference shall be to a Section,
subsection, Schedule or Exhibit to this Agreement unless otherwise indicated.
The words "include"," "includes" and "including" when used herein shall be
deemed in each case to be followed by the words "without limitation." The word
"herein" and similar references mean, except where a specific Section or
Article reference is expressly indicated, the entire Agreement rather than any
specific Section or Article. The table of contents and the headings contained
in this Agreement are for reference purposes only and shall not affect in any
way the meaning or interpretation of this Agreement.

   4.6 Severability. If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of Law, or public
policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions

                                      C-5
<PAGE>

contemplated hereby is not affected in any manner adverse to any party. Upon
such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the parties as
closely as possible in an acceptable manner to the end that transactions
contemplated hereby are fulfilled to the extent possible.


   4.7 Entire Agreement; No Third Party Beneficiaries. This Agreement, the
Merger Agreement and the other Related Agreements constitute the entire
agreement and supersedes all prior agreements and understandings (other than
the Confidentiality Agreement), both written and oral, among the parties with
respect to the subject matter hereof and thereof, and is not intended to confer
upon any Person other than the parties hereto any rights or remedies hereunder.

   4.8 Amendments; Assignment. This Agreement may not be amended except by
written agreement by all the parties. This Agreement shall be binding upon and
inure to the benefit of the parties and their respective successors and
permitted assigns. Neither this Agreement nor any of the rights, interests or
obligations under this Agreement shall be assigned, in whole or in part, by any
of the parties without the prior written consent of the other parties, and any
purported assignment without such consent shall be void; provided that Parent
may assign its rights and obligations hereunder to any direct or indirect
wholly owned subsidiary of Parent without such consent.

   4.9 Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or
delay on the part of any party hereto in the exercise of any right hereunder
will impair such right or be construed to be a waiver of, or acquiescence in,
any breach of any representation, warranty or agreement herein, nor will any
single or partial exercise of any such right preclude other or further exercise
thereof or of any other right. All rights and remedies existing under this
Agreement are cumulative to, and not exclusive to, and not exclusive of, any
rights or remedies otherwise available.

   4.10 Governing Law; Enforcement. This Agreement and the rights and duties of
the parties hereunder shall be governed by, and construed in accordance with,
the Law of the State of New York. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached.
It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in the Federal District Court for
the Southern District of New York, this being in addition to any other remedy
to which they are entitled at law or in equity. In addition, each of the
parties hereto, (a) consents to submit itself to the personal jurisdiction of
the Federal District Court for the Southern District of New York in the event
any dispute arises out of this Agreement or any transaction contemplated
hereby, (b) agrees that it will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court, (c)
agrees that it will not bring any action relating to this Agreement or any
transaction contemplated hereby in any court other than the Federal District
Court for the Southern District of New York and (d) waives any right to trial
by jury with respect to any action related to or arising out of this Agreement
or any transaction contemplated hereby.

   4.11 Counterparts. This Agreement may be executed in one or more
counterparts, and by the different parties hereto in separate counterparts,
each of which when executed shall be deemed to be an original but all of which
taken together shall constitute one and the same agreement.

                      FleetBoston Robertson Stephens Inc.

                                                               December 21, 1999

Board of Directors
MapQuest.com, Inc.
3710 Hempland Road
Mountville, Pennsylvania 17554

Members of the Board:

   We understand that MapQuest.com, Inc. (the "Company"), America Online, Inc.
("Acquiror") and MQ Acquisition, Inc. (a wholly owned subsidiary of Acquiror,
"Merger Sub") are proposing to enter into an Agreement and Plan of Merger
(together with the agreements attached thereto as exhibits, including the
Stockholders Agreement (the "Stockholders Agreement") and the Stock Option
Agreement, the "Agreement") which will provide, among other things, for the
merger (the "Merger") of Merger Sub with and into the Company. Upon
consummation of the Merger, the Company will become a wholly owned subsidiary
of Acquiror. Under the terms set forth in a draft of the Agreement dated
December 21, 1999 (the "Draft Agreement"), at the effective time of the Merger
(the "Effective Time"), each share of common stock of the Company, par value
$.001 per share ("Company Common Stock") issued and outstanding immediately
prior to the Effective Time, other than certain shares to be canceled pursuant
to the Agreement, will be converted into the right to receive 0.31558 of a
share (the "Exchange Ratio") of the common stock of Acquiror, par value $0.01
per share ("Acquiror Common Stock"). The terms and conditions of the Merger are
set out more fully in the Agreement.

   You have asked us whether, in our opinion, the Exchange Ratio is fair from a
financial point of view and as of the date hereof to the "Holders of Company
Common Stock". The "Holders of Company Common Stock" shall be defined as all
holders of Company Common Stock other than Acquiror, Merger Sub or any
affiliates of Acquiror or Merger Sub (holders of Company Common Stock will not
be considered to be affiliates of Acquiror or Merger Sub simply by virtue of
entering into the Stockholders Agreement).

   For purposes of this opinion we have, among other things:

     (i) reviewed certain publicly available financial statements and other
  business and financial information of the Company and Acquiror,
  respectively;

     (ii) reviewed with the Company certain publicly available estimates of
  research analysts relating to the Company;

     (iii) reviewed certain publicly available estimates of research analysts
  relating to Acquiror;

     (iv) held discussions with the respective managements of the Company and
  Acquiror concerning the businesses, past and current operations and
  financial condition of both the Company and Acquiror and also the future
  prospects of the combined company, including discussions with the
  managements of the Company and Acquiror concerning their views regarding
  the strategic rationale for the Merger;

     (v) reviewed the financial terms and conditions set forth in the Draft
  Agreement;

     (vi) reviewed the stock price and trading history of Company Common
  Stock and Acquiror Common Stock;

     (vii) compared the financial performance of the Company and the prices
  and trading activity of Company Common Stock with that of certain other
  publicly traded companies comparable with the Company;

     (viii) compared the financial terms of the Merger with the financial
  terms, to the extent publicly available, of other transactions that we
  deemed relevant;

                                      D-1
<PAGE>

     (ix) reviewed the pro forma impact of the Merger on Acquiror's revenue
  per share and earnings per share;

     (x) prepared an analysis of the relative contributions of the Company
  and Acquiror to the combined company;

     (xi) participated in discussions and negotiations among representatives
  of the Company and Acquiror and their financial and legal advisors; and

     (xii) made such other studies and inquiries, and reviewed such other
  data, as we deemed relevant.

In our review and analysis, and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and
other information provided to us (including information furnished to us orally
or otherwise discussed with us by the managements of the Company and Acquiror)
or publicly available and have neither attempted to verify, nor assumed
responsibility for verifying, any of such information. We have relied upon the
assurances of the Company's management that it is not aware of any facts that
would make such information inaccurate or misleading. Furthermore, we did not
obtain or make, or assume any responsibility for obtaining or making, any
independent evaluation or appraisal of the properties, assets or liabilities
(contingent or otherwise) of the Company or Acquiror, nor were we furnished
with any such evaluation or appraisal. With respect to the publicly available
estimates of research analysts (and the assumptions and bases therefor) for
each of the Company and Acquiror that we have reviewed, we have assumed that
such forecasts and projections have been reasonably prepared in good faith on
the basis of reasonable assumptions and reflect the best currently available
estimates and judgments as to the future financial condition and performance
of the Company and Acquiror, respectively. In this regard, we note that each
of the Company and Acquiror face exposure to the Year 2000 problem. We have
not undertaken any independent analysis to evaluate the reliability or
accuracy of the assumptions made with respect to the potential effect that the
Year 2000 problem might have on the Company's and Acquiror's respective
forecasts. The only financial forecasts and projections that we used in our
analysis were the publicly available estimates of research analysts. We have
assumed that the Merger will be consummated upon the terms set forth in the
Draft Agreement without material alteration thereof, including, among other
things, that the Merger will be accounted for as a "pooling-of-interests"
business combination in accordance with U.S. generally accepted accounting
principles ("GAAP") and that the Merger will be treated as a tax-free
reorganization pursuant to the Internal Revenue Code of 1986, as amended. In
addition, we have assumed that the historical financial statements of each of
the Company and Acquiror reviewed by us have been prepared and fairly
presented in accordance with U.S. GAAP consistently applied. We have relied as
to all legal matters relevant to rendering our opinion on the advice of
counsel.

   This opinion is necessarily based upon market, economic and other
conditions as in effect on, and information made available to us as of, the
date hereof. It should be understood that subsequent developments may affect
the conclusion expressed in this opinion and that we disclaim any undertaking
or obligation to advise any person of any change in any matter affecting this
opinion which may come or be brought to our attention after the date of this
opinion. Our opinion is limited to the fairness, from a financial point of
view and as to the date hereof, to the Holders of Company Common Stock of the
Exchange Ratio. We do not express any opinion as to (i) the value of any
employee agreement or other arrangement entered into in connection with the
Merger, (ii) any tax or other consequences that might result from the Merger
or (iii) what the value of Acquiror Common Stock will be when issued to the
Company's stockholders pursuant to the Merger or the price at which the shares
of Acquiror Common Stock that are issued pursuant to the Merger may be traded
in the future. Our opinion does not address the relative merits of the Merger
and the other business strategies that the Company's Board of Directors has
considered or may be considering, nor does it address the decision of the
Company's Board of Directors to proceed with the Merger.

   We are acting as financial advisor to the Company in connection with the
Merger and will receive (i) a fee contingent upon the delivery of this opinion
and (ii) an additional fee contingent upon the consummation of the Merger. In
addition, the Company has agreed to indemnify us for certain liabilities that
may arise out of our

                                      D-2
<PAGE>

engagement. In the past, we have provided certain investment banking services
to the Company for which we have been paid fees, including acting as lead
manager on the Company's initial public offering. We maintain a market in the
shares of Company Common Stock and Acquiror Common Stock. In the ordinary
course of business, we may trade in the Company's securities and Acquiror's
securities for our own account and the account of our customers and,
accordingly, may at any time hold a long or short position in the Company's
securities or Acquiror's securities.

   Our opinion expressed herein is provided for the information of the Board of
Directors of the Company in connection with its evaluation of the Merger. Our
opinion is not intended to be and does not constitute a recommendation to any
stockholder of the Company as to how such stockholder should vote, or take any
other action, with respect to the Merger. Except as may have otherwise been
agreed by us in writing, this opinion may not be summarized, described or
referred to or furnished to any party except with our express prior written
consent.

   Based upon and subject to the foregoing considerations, it is our opinion
that, as of the date hereof, the Exchange Ratio is fair to the Holders of
Company Common Stock from a financial point of view.

                                      Very truly yours,

                                      FleetBoston Robertson Stephens Inc.
